CHARACTERIZATION OF XYLANASE ENZYME PRODUCED BY Bacillus subtilis. Dimpal J Aghera & Jigna H Patel
Department of Biochemistry
The M. S. University of Baroda, Vadodara 390002
Xylanase is a class of enzymes which is produced by microorganisms. Xylanase degrades xylan
into monomers of various sizes by catalysing, possessing potential in wide industrial applications,
along with uses in agriculture and for human health. Xylanase has applications in the food and
paper making industries. There are different types of xylanases produced by different type of
microorganisms. These enzymes act under different conditions, such as different pH levels,
different salt levels, and different temperatures, different salts and different solvents. Xylanase is
industrially important enzyme which is produced by natural resources like agricultural waste.
Bacillus subtilis is a Gram-positive bacterium which is isolated from farm soil. Xylanase enzyme
produced by Bacillus subtilis was partially purified by 70% ammonium sulphate saturation.
Different temperatures (20°C,30°C,40°C,50°C,60°C,70°C), pH (4,5,6,7,8,9,10), salt concentration
(0%,1%,2%,5%,10%,15%,20%) different metal salts like BaCl2, CaCl2, FeCl3, HgCl2, KCl,
MnCl2, NaCl, MgSO4, different inhibitors like SDS, EDTA, CTAB, Urea and different solvents
like methanol, ethanol, butanol, acetone, isoamyl alcohol, chloroform, isopropanol, n-hexane were
experimented for the characterization of enzyme. Enzyme is found to be stable at various
conditions.
ANTIMICROBIAL AND ENZYMATIC POTENTIAL OF ACTINOBACTERIA
ASSOCIATED WITH SEA WEED DICTYOPTERIS SP. Krishna B. Bhutiya and Sangeeta D. Gohel
Department of Biochemistry
The M. S. University of Baroda, Vadodara 390002
Seaweeds are sessile multicellular photosynthetic eukaryotes that are differentiated from plants by
their lack of specialized tissues. The seaweeds are ecologically important primary producers,
competitors, and ecosystem engineers that play a central role in coastal habitats ranging from kelp
forests to coral reefs. They are the part of highly productive ecosystems and are habitats of
numerous bioactive compounds producing microorganisms. Actinobacteria are one of the active
marine bacteria which are heterogeneous group of gram positive, high G+C bacteria noted for a
filamentous and branching growth pattern. Thus, the present study focused on actinobacteria
species associated with Dictyopteris sp. Total10 actinobacterial strains were isolated from
Dictyopteris sp. from the coastal region of Veraval, Gujarat, India. The selected actinobacterial
strains displayed consistent antimicrobial and antifungal activity along with enzymatic potential.
The actinobacteria strain Ds-11 showed comparatively batter antimicrobial activity against E. coli,
Proteus sp., Shigella sp., B. subtilis, B. megaterium, B. cereus and E. faecalis and antifungal
7
activity against A. niger and A. flavus. Whereas, actinobacteria strain Ds-11 secreted
comparatively high protease on gelatin agar medium supplemented with 0-10 % NaCl (w/v). The
effect of various physical and chemical parameters such as pH, temperature and salt on the growth
and protease production was studied in liquid culture medium. The actinobacteria strain Ds-11
produced protease even at 10% NaCl (w/v) in liquid culture media while the protease production
was optimum at 6% NaCl (w/v).

The Value of Learning Science Beyond the potential scientific breakthroughs, there are individual
benefits to learning science, such as developing our ability to ask questions, collect information,
organize and test our ideas, solve problems, and apply what we learn.
Insulin is very important for the metabolism of glucose in the body. If its amount increases or
decreases, some defects occur in the body. for example, Diabetes. This insulin is first obtained
from the pancreas of cattle taken to the slaughterhouse but is not in pure form, which can lead to
many diseases. To prevent this, biotechnology was invented using science platforms. Man-made
insulin was then made. Thus, science always provides a platform to learn something new.
Sonam Wangchuck has recently set up a tent in Ladakh for the Indian Army, which is very useful
for soldiers. Thus, Science always provides a platform to learn and do something new.
Just as water is universal, so is science universal. Science has a vast ocean.

CYTOGENETIC STUDY IN CRIMINALS (MURDERERS): ROLE OF XYY CHROMOSOME IN
CRIMINALITY
Yash Darji & Nikunj Parmar
Dr. Vikram Sarabhai Institute of Cell & Molecular Biology
The M. S. University of Baroda, Vadodara-390002
Crime & criminals are a curse to society. All types of advanced scientific methods should be used
for detection of crime to prove the guilt of criminal and also to see that innocent subjects are not
victimized. Although there are many methods of detecting crime, cytogenetic study has a unique
character of its own in its application to forensic science. The crime rates in India are increasing
and approximately 5% of the criminals are murderers. the famous Danish `Adoption Studies`
states that in addition to socio-economic factors, hereditary plays an important role in the
determination of criminality. In this study an attempt has been made to find out if there is any
definite association between the criminality and chromosomal aberrations. Hence the individuals
who were convicted by the court of law under IPC 302 as murderers are subjected to that there is
a definite association between the criminal behaviour and XYY chromosome. It's also suggested
that this positive association should be studied in a large population before this observation can
be used as a biological indicator of criminality.
AGEING AT CELLULAR LEVEL: ROLE OF TELOMERES AND GENES
Dhruva Bhatt
Dr. Vikram Sarabhai Institute of Cell & Molecular Biology
The M. S. University of Baroda, Vadodara 390002
Ageing occurs when intrinsic processes and interactions with the environment that leads to the
failure of the whole organism.
One of the most prominent causes of ageing at a cellular level is the shortening of telomeres and
subsequent formation of senescent cells. Mitotic somatic cells divide continuously till they reach
their programmed cell death. This programmed cell death happens after the cell undergoes a certain
number of divisions called the Hayflick Limit. The cause lies in the telomeres, originally made
from telomerase enzyme during zygote stage. Every time a cell divides, the telomeres on
chromosomes are a bit shorter than those in the parent cell. This occurs due to the intrinsic inability
of DNA polymerases to completely replicate the telomere C-rich lagging-strand. During the
process of lagging-strand synthesis, RNA primers come into play allowing DNA polymerases to
initiate DNA replication. However, upon removal of the last primer at the 3′ end, the newly
synthesized strand will inevitably be a few nucleotides shorter, resulting in loss of telomere
repeats. First hypothesized independently by Olonikov and Watson, this phenomenon was
confirmed experimentally in nineties. When the telomeres become so short that further division
may cause damage to coding sequence of DNA, the cell reaches replicative senescence and
becomes a senescent cell. They decrease effective tissue and organ function and may lead to age
related diseases.
10
Furthermore, genes are essential in determining the age of an organism. In a research conducted
by Cynthia Kenyon on C. elegans suggested that a single gene DAF-2 caused them to age and
when mutated, worms lived twice as long. In humans, research is focused upon one gene that
produces a growth hormone called the IGF-1 gene. In experiments done on mice, it was observed
that silencing this gene increased the lifespan by 33%, however there have been no human trials.
It was also suggested that calorie intake stimulates IGF-1 to direct food and energy towards growth,
shifting the metabolism from maintaining the existing cells and building resistance; to growing
Some ways to slow down/reverse the aforementioned processes can be observed in stem and
cancer cells that have their own telomerase and can divide indefinitely without their chromosomes
getting damaged. Due to risk of potential tumor, injecting telomerase to cells could be done
following proper research and experimentation. Scientists have also tried to genetically engineer
mice so they can destroy their senescent cells when they pleased, leading to an increase in survival
up to 30%.

HOW CARBOHYDRATES CAN BE TARGETED FOR VACCINE DEVELOPMENT? Pooja Sandip Shah, Roshni Janakkumar Patel, Ruchi Rajendrabhai Patel
Dr. Vikram Sarabhai Institute of Cell & Molecular Biology
The M. S. University of Baroda, Vadodara 390002
Carbohydrates structures decorate the surface of the pathogens and malignant cells and could be
exploited as potential targets for vaccine design. Indeed, most vaccines against the bacterial
infections are carbohydrate vaccines.
The steady increase in drug resistance has catalysed a renewed interest in carbohydrate vaccine
development against wide range of pathogens as well as cancer.
A number of challenges are associated with targeting glycan structure in a vaccine context.
Generally speaking, the main challenges include the poor immunogenicity of carbohydrates, low
affinity of protein-carbohydrate interactions, and structural diversity of glycans between species
or strains and micro-heterogenicity.
Using carbohydrates to induce immunity is relatively a new strategy.
The poor quality of the antibody responses to carbohydrate is one of the many obstacles with
developing carbohydrate-based vaccines and is largely attributed to T-cell independent immune
response, which are typically triggered by repetitive carbohydrate antigens.
B cell receptor cross linking through binding repetitive motifs activate antigen-specify B cells
independent of CD4- helper T cells. Such T cells independent responses are less robust, short lived
and primarily consist of IgM antibodies. By contrast, CD4- T cells, which are typically generated
in response to proteins, enable the generation of high affinity; class- switched antibodies and
subsequently, long lived antibody mediated protection. Zwitter ionic capsular polysaccharide from
some bacteria is exception as these carbohydrates, like proteins, can be processed and presented
on major histocompatibility complex class2 molecules for activation of CD4 – helper T cells and
the generation of T cells dependent immune responses. To recruit CD4 T cells for antibody
responses against the vast majority of glycans, exogenous CD4 T cell epitopes must be provided,
usually in the form of a carrier protein. Bacteria capsular polysaccharide repeats associated with
particular species (and serotypes).
As early as 1931, Avery and Goedel reported that conjugation of glycans to a suitable protein
scaffold enhanced to immunogenicity of carbohydrates. It is now well known that immunisation
with neoglyco-conjugates composed of capsular polysaccharide - derived glycans covalently
coupled to an immunogenic protein carrier (conjugate vaccines) induces long - lasting protection
against encapsulated bacteria.

DESIGNER BABY
Dwisha Raval, Sneh bhalani &Shreya Basu
Dr. Vikram Sarabhai Institute of Cell & Molecular Biology
The M. S. University of Baroda, Vadodara 390002.
The term 'designer baby' refers to a baby that has been given special traits through genetic
engineering. This is done by altering the genes of the egg, sperm, or the embryo. These traits can,
in theory, vary from lower resistance to diseases to even gender selection.
Adam Nash is considered to be the first designer baby, born in 2000 using in vitro fertilization
with pre-implantation genetic diagnosis, a technique used to choose desired characters
When you alter a baby’s genetic makeup to remove a particular gene(s) associated with a disease,
you successfully create a designer baby. One way is to use a process is called preimplantation
genetic diagnosis. This process analyses a wide range of human embryos associated with a
particular disease and selecting seeds that have the desired genetic makeup.
Another less popular method is called Germline engineering, which enables altering a baby’s
genetic information before birth. The desired genetic material is introduced into the embryo itself
or the sperm and egg cells, either by delivering the selected genes directly into the cell or using
the gene-editing technology.
Genetic editing is done either by removing small sections of the existing genome or by introducing
new segments of DNA into the genome. CRISPR (Clustered Regularly Interspaced Short
Palindromic Repeats) is a genome editing technology introduced by researchers Emmanuelle
Charpentier and Jennifer Doudna. The technology allows scientists to cheaply and very rapidly
alter the genome of almost any organism. CRISPR makes use of an enzyme called Cas-9, which
is used to cut out selected sections of DNA or and add new units to existing DNA.
For example the eye colour of the embryo can be designed by following conditions-(enrolment of
eye colour selection program)
parents carry the genetic codes, or “building blocks” of the eye colour they wish to choose for their
child, undergoing the actual fertility procedure that will allow the scientists and physicians to
examine the embryos you produce with in vitro fertilization to determine which of the embryos
carry the genes necessary to greatly increase the chance of the chosen eye colour.
Over generations, gene editing could affect entire gene pools. For screening of Down Syndrome
in kids in Britain, promote vaccines to eliminate illnesses, and now there is embryo testing for
eradicating genetic conditions.
It gives an opportunity to the parents to give their child a better shot at a healthy lifestyle, Prevents
genetic diseases such as Down Syndrome, Alzheimer’s, Huntington’s Disease, Spinal Muscular
Atrophy, and many others. Reduces risk of inherited medical conditions such as obesity, anaemia,
diabetes, cancer, etc.

INJECTABLE OXYGEN MICROPARTICLES
Shruti Panchal, Rushali Mehta & Yeshaba Zala
Dr. Vikram Sarabhai Institute of Cell & Molecular Biology
The M. S. University of Baroda, Vadodara 390002
Scientists have developed an injectable foam suspension containing self-assembling, lipid base
microparticles encapsulating the core of pure oxygen gas for Intravenous injection.
The microparticles used to package oxygen gas, covered by a layer of fatty molecules and
stabilizing agents. Lipidic oxygen containing microparticles are called LOM. They usually store
energy or serve as a component to cell membranes.
Upon contact with the oxygen-poor Red blood cells, it releases Oxygen, which rapidly bind to the
cell. The lipid shell is metabolized by the body. The study details the development of an Oxygen
gas filled microparticles that could keep us alive, even if we can’t perform the physical act of
breathing for 15 minutes. There are several theoretical approaches rapidly increasing arterial
Oxygen content in the setting of an emergency. The most obvious may be directly bubbling
Oxygen gas into bloodstream. Historically, direct infusion of free Oxygen gas into bloodstream
has resulted in pulmonary emboli. At extremely low infusion rates corresponding to only 8% of
measured oxygen consumption of a healthy human adult. Due to the introduction of nanoparticles
or microparticles of Oxygen, the pulmonary emboli can be prevented.
The plot for Oxyhaemoglobin Vs Time gives all the useful information regarding the experiment.
CELLS' SENSE AND ADAPTIBILITY TO OXYGEN AVAILIBILITY
Rahul Patel, Maitreyi Rohra & Juhi Shah
Dr. Vikram Sarabhai Institute of Cell & Molecular Biology
The M. S. University of Baroda, Vadodara 390002
In this project we are going to try to understand how cells sense and adapt to the oxygen
availability in the environment by identifying the molecular machinery that regulates the activity
of genes in response to varying levels of oxygen.
We will be discussing how this seminal discovery has revealed the mechanism for one of life's
most essential adaptive processes by establishing the basis for our understanding of how oxygen
levels affect cellular metabolism and physiological function. And we will be also looking for how
it has paved the way for new strategies to fight anemia, cancer and many other diseases.
As we know till now, various mechanisms have been developed in the course of time through
evolution in our body which ensure sufficient supply of oxygen to the tissues and cells.
The discoveries in 1938 by Corneille Heymans which won the Nobel Prize in Physiology and
medicine was about How the blood oxygen levels were sensed via a specialized cell adjacent to
the large blood vessels on both the sides of our neck called the carotid cells controlled the
respiratory rate by communicating directly with the brain. In addition to carotid body-controlled
hypoxia there are other fundamental physiological adaptations such as rise in the level of the
14
hormone erythropoietin which leads to the increased production of red blood cells, which is
increased erythropoiesis. The importance of the hormonal control of erythropoiesis was already
known at the beginning of 20 century but how this process was itself controlled by oxygen was
discovered in 2019 by William G. Kaelin Jr., Sir Peter J. Ratcliffe and Gregg L. Semenza in their
various studies of the EPO gene, the HIF factor and etc.
Thus, we will be exploring all the responsible factors, genes, mechanisms which play a role in the
sensing and adaptation of our cells in response to the availability of oxygen.

Bioprinting technology has emerged as a powerful tool for building tissue and organ structures in
the field of tissue engineering. This technology allows precise placement of cells, biomaterials and
biomolecules in spatially predefined locations within confined three-dimensional (3D) structures.
Various bioprinting technologies have been developed and utilized for applications in life sciences,
ranging from studying cellular mechanisms to constructing tissues and organs for implantation,
including heart valve, myocardial tissue, trachea and blood vessels. Here I have taken, the general
information of the most widely used bioprinting technologies. Application-based research focused

As many of us know that the field cell and molecular biology is very scopeful and less competitive
field. But there are a lot many students/people who are not at all aware about this field. They don’t
know about how interesting this field is and its expediency. So, through my topic (poster-video) I
am trying to make people/students aware about this field. Cell and Molecular Biology studies the
structure and function of the cell, which is the basic unit of life. Cell biology is concerned with the
physiological properties, metabolic processes, signaling pathways, life cycle, chemical
composition and interactions of the cell with their environment. This is done both on a microscopic
and molecular level as it encompasses prokaryotic cells and eukaryotic cells. Knowing the
components of cells and how cells work is fundamental to all biological sciences; it is also essential
for research in bio-medical fields such as cancer, and other diseases. Research in cell biology is
closely related to genetics, biochemistry, molecular biology, immunology and cytochemistry.
CMB provides students with a solid foundation in cell biology, molecular biology, microbiology,
biochemistry, and molecular genetics. Further, experiential learning is an integral part of this
15
degree program. This training will enable students to make meaningful contributions to global
medical and environmental issues including the study of the molecular basis of cancer and
infectious disease, heart disease, the development of next generation biofuels, and the genetic
engineering of crops for increased productivity and improved disease resistance. I hope that my
message aware all students/people.
ASPECTS OF HUMAN CLONING
Dhara Patel, Shriya Varma, Shaliha Pathan
Dr. Vikram Sarabhai Institute of Cell & Molecular Biology

Cloning is the process of producing individuals with identical or virtually identical DNA, either
naturally or artificially. In nature, many organisms produce clones through asexual reproduction.
Cloning in biotechnology refers to the process of creating clones of organisms or copies of cell.
There are three different types of artificial cloning: gene cloning, reproductive cloning and
therapeutic cloning. Gene cloning produces copies of genes or segments of DNA. Reproductive
cloning produces copies of whole animals. Therapeutic cloning produces embryonic stem cells for
experiments aimed at creating tissues to replace injured or diseased tissues. In reproductive
cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they
wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or
oocyte, that has had its own DNA-containing nucleus removed. Researchers can add the DNA
from the somatic cell to the empty egg in two different ways. Several mammalian species have
been cloned by transferring nuclei from various adult somatic cells into enucleated oocytes. The
cloning procedure is still inefficient, and only one in a hundred of manipulated oocytes develop to
adulthood. Reasons for the low efficiency of cloning are unknown and are probably both technical
and biological. The incomplete or incorrect reprogramming of the donor nuclear genome — its
inability to completely adapt and function in the new environment — is the most significant factor
contributing to low cloning efficiency. The cloning of large farm animals from genetically
manipulated donor nuclei will have significant practical benefits. Benefits of cloning include
being able to create tissue and organs that doctors can use when needed for surgery on the
original. Other benefits include growing stem cells, cloning lab mice genetically engineered for
the specific study, bringing back extinct species, reproducing a pet that died and cloning
livestock for food.
Several risks involved in of human cloning are
It risks the possibility of faster aging and It interferes with nature.
It can bring forth a reduced sense of individuality.
It can cause a divide among people.
It might decrease the overall value of human life.
It goes against religious ethics.
It might be used for exploitation.

CRYO-ELECTRON MICROSCOPY: 2017 NOBLE PRIZE
Rohan. M. Dhomse & Kavan Chauhan
Department of Chemistry
The M.S. University of Baroda, Vadodara 390002
The 2017 Nobel Prize in Chemistry was awarded to the following three pioneers: Dr. Joachim
Frank, Dr. Jacques Dubochet, and Dr. Richard Henderson. They all contributed to the development
of a Cryo-electron microscopy (EM) technique for determining the high-resolution structures of
bio molecules in solution, particularly without crystal and with much less amount of bio molecules
than X-ray crystallography.
Cryo-EM is a suitable technique for visualizing radiation-sensitive specimen like biological
macromolecules or soft matter materials consisting of light atoms such as organic polymers. In the
cryo-EM procedure, specimens are created by rapid freezing of biomolecules in solution and
loaded into the column of an electron microscope operating at high-vacuum and at low temperature
to keep the ice in amorphous state and to reduce the effect of radiation damage. Unlike X-ray
crystallography and NMR spectroscopy, cryo-EM requires a much smaller amount of sample and
it accepts a larger variation of specimen types, such as single protein molecules, large protein
complexes, thin-protein crystals, virus particles, helical fibre complexes, bacteria, cells and even
entire tissue sections.
Modern cryo-electron microscopy (cryo-EM) began with the introduction of a unique specimen
preparation method by Dubochet and co-workers in the 1980s resulting in the preservation of
biological specimens at near native condition within a thin amorphous ice film, which allowed
direct observation on a low dose transmission electron microscope operating at liquid nitrogen
temperature or below.
This technique has an advantage in that it can be used to view and characterize a wide range of
samples. Using cryo-electron microscopy, it becomes possible to view cells, cell organelles as well
as macromolecules complexes of well over 500 kD.
Disadvantages: -Very low signal to noise ratio & Tilt Imaging
Here, we give a review of cryo-EM and introduce the technique as one of the modalities for
studying molecular dynamics in proteins and protein complexes. Compared with other methods,
cryo-EM covers a larger range of molecular weights and sample conditions. Even the structure of
proteins inside the cell can now be analysed. Cryo-EM, a just recently matured technique, is a
strong contender to contribute novel insights for the study of molecular dynamics of proteins in
the future.

ELEPHANT TOOTHPASTE

Department of Chemistry

Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen
peroxide using potassium iodide or yeast and warm water as a catalyst.This experiment shows the
catalysed decomposition of hydrogen peroxide. Hydrogen peroxide (H2O2) decomposes into
water and oxygen gas, these bubbles of Oxygen would usually escape from the liquid and pop
quickly. But adding a little dish soap provides additional surface tension, allowing the bubbles to
get trapped and creating lots of foam. This foam looks like a giant squeeze of toothpaste—almost
big enough for an elephant!
In normal conditions, this reaction takes place very slowly, therefore a catalyst is added to speed
up the reaction, which will result in rapid formation of foam. The iodide ion from potassium iodide
acts as a catalyst and speeds up the reaction while remaining chemically unchanged in the reaction
process.
The reaction is exothermic.
GLOW STICK EXPERIMENT
Patel Ajaykumar Manibhai, Mayuri Shaiwale, Varsha Bharadwaj
Department of Chemistry
The M. S. University of Baroda, Vadodara 390002
Glow sticks consist of two separate compartments with
two different chemical solutions. One solution,
contained within an inner glass cylinder, is
18
hydrogen peroxide. In the case of most glow sticks, the
other solution surrounding the glass cylinder contains a
diphenyl oxalate compound along with a fluorescent dye.
The inner glass cylinder keeps the two solutions separated
to prevent their reaction. The action of snapping the glow
stick breaks the glass cylinder, allowing the two solutions
to mix and initiate the chemical reaction. The reaction
occurs between the H2O2 (hydrogen peroxide) and the
diphenyl oxalate. When the two solutions are mixed,
hydrogen peroxide oxidizes the diphenyl oxalate ester,
which produces phenol plus an unstable compound called
1,2- dioxetanedione. This unstable ester breaks apart
releasing energy and CO2. The energy gets transferred to
the dye molecule causing the electrons to jump to higher
levels. The dye molecule finally relaxes back to the ground
state, with the release of a photon of light at a specific
frequency which our eyes can see because it falls in the
visible range of the electromagnetic spectrum
BLUE BOTTLE EXPERIMENT
Samridhi Parayil
Department of Chemistry
The M.S. University of Baroda, Vadodara 390002
The blue bottle experiment is a color changing, redox chemical reaction.
This experiment only requires 3 reagents; methylene blue, glucose solution and sodium hydroxide.
These reagents are mixed and then the flask is covered shut.
Glucose (an aldohexose sugar) in alkaline medium gets slowly converted into gluconic acid by
oxygen present in the atmosphere:
CH2OH-(CHOH)4-CHO + ½O2 → CH2OH-(CHOH)4-CO2H
In the presence of NaOH, gluconic acid is converted into gluconate. Methylene blue speeds up the
reaction furthermore acting as an oxygen transfer agent.
The initial colour of the solutions is blue, as the reaction proceeds, the alkaline glucose solution
reduces the methylene blue to a colourless leuco methylene blue, and the blue colour of the solution
gradually fades and then disappears.
19
On shaking the flask again, the colour changes back to the initial blue colour.
This happens because of the oxidation of leuco methylene back to methylene blue, as the shaking
causes oxygen from the head space air dissolve in the solution. On standing the solution again it
becomes colorless.
This reaction can be repeated couple of more times.
CARBON DIOXIDE: FIRE EXTINGUISHER
Rushik Vasava and Komal Kolte
Department of Chemistry
The M. S. University of Baroda, Vadodara 390002
Carbon dioxide, which weighs more than oxygen. Fire needs oxygen and fuel to burn. These three
components are called the fire triangle or the combustion triangle. Taking just one of these things
away will make the fire go out. Oxygen is a gas present in the atmosphere. When we placed the
carbon dioxide over the flame, the carbon dioxide replaced the oxygen. This caused the fire to die
because it was not getting oxygen.
The (sodium bicarbonate) is a base and vinegar (acetic acid) is weak acid. When they combine,
the immediate reaction creates carbonic acid. However, carbonic acid is very unstable and it
quickly decomposes into and water (H2O). A carbon dioxide (CO2) gas that is heavier than oxygen
(O2), it stays in the bottle.
As it pours out of the bottle, it pushes the lighter oxygen away from the candle. The fire, now
deprived of oxygen, can no longer burn.
ACETONE FLASHLIGHT

Acetone flashlight experiment is based on the catalytic oxidation of acetone by copper exothermic
process regeneration of original copper metal. A copper wire is heated and suspended above the
surface of acetone in a beaker, the copper surface of the hot wire catalyzes the oxidation of acetone.
Hot copper reacts with oxygen in the air to produce a coating of copper oxide, CuO. The copper
oxide reacts with acetone, producing ketene and methane and regenerating copper metal. Reaction
20
with acetone, the copper surface becomes bright because of the transfer of the oxygen and begins
to glow red hot because of the energy that's released from the reaction. In this reaction a great deal
of heat is released, so the copper wire does not cool down, and heats up even more, which explains
why it glows. This exotherm keeps the wire glowing. In the absence of oxides on the copper
surface the copper glows yellow in the reducing gas mixture. The flicking on the surface of the
wire is caused by the changing of temperature. As the vapor touches the surface, the copper wire
alternately cools down and then glows again.

Drugs or pharmaceuticals are those chemicals which are used as medicines to cure, halt or prevent
diseases; ease symptoms; or help in diagnosis of illnesses. Nowadays, these chemicals are very
important in one’s life. There are many industries all over the world which produces tons of
medicines over a year. These are often excreted unchanged and can reach the environment.
Throughout developed countries, the pharmaceuticals in the aquatic environment are in the same
range (µg L-1 and below); however, it is not clear whether this holds for developing countries too.
This can cause water pollution and we can denote it by pharmaceutical pollution.
In this video, a detailed explanation about pharmaceutical pollution is given. These can reach to
water sources by excretion or directly as a waste without any treatment. As bioavailability of drugs
can’t be 100%, most of the ingested drugs go to the sewage. This increases TDS, BOD, COD and
other water quality parameters. Although there is no proper evidence, this can lead human health
to risk and chances of getting ill may be increased. This drug pollution can affect fertility of
agricultural land and also aquatic lives. We need to aware people about and how to prevent this is
discussed precisely in the video.
In addition to drug pollution, drug addiction is explained here. Reasons to get addicted, common
drugs which are utilized by drug addicts, their mental, biological and social effects and how to
surmount this situation is also briefly described.

What do you think what would happen if I decided to light a piece of paper??
You were right, it would burn!! But here the case is little different…
21
When the currency note is soaked into the solution of 50ml of ethyl alcohol and 50ml of water, the
water molecule soaked into the currency note, while alcohol remains on the surface. When the
match is put to the currency note, the alcohol is what actually burns. The temperature at which
alcohol burns is not high enough to evaporate the water and burs the currency note. So after the
alcohol has burned, the currency note is slightly wet and fire goes out.
Here the combustion reaction is:
C2H5OH + 4O2 --------> 2CO2 +3H2O + Heat Energy
Here we also add different metal salts into the solution of alcohol and water so we get its
corresponding flames.
For example: Lithium salts: Red flame, copper salts: blue flame, Barium salts: apple green flame
CHEMICAL TRAFFIC LIGHT

Department of Chemistry

The chemical traffic light is a color-changing redox reaction that consists of glucose, sodium
hydroxide, indigo carmine, and water. When all chemicals are added together then the color
appears yellow. After shaking, the color turns green and then changes to red after it is left
untouched.
This reaction occurs by oxidation and reduction of the solution where alkaline glucose solution is
acting as a reducing agent. When the glucose solution is added to the solution containing indicator
(dye indigo carmine) the color changes occur. When solution is shaken, oxygen dissolves in the
22
solution and oxidizes indigo carmine. Solution becomes red if a small amount of oxygen is
dissolved, and green if all of indigo carmine is oxidized. The solution will turn back to original
yellow color when the concentration of oxygen level drops. Due to this reversible color change
this reaction is called chemical traffic light.

Magnesium silicide can be made by heating magnesium power (5 g) and an excess of white sand
(10 g) in a soda-glass test tube over a roaring Bunsen flame. After a short time an exothermic
reaction takes place, producing intense heat and a red glow accompanied by a loud pop. The first
product is silicon, which reacts with magnesium to produce Mg2Si Interestingly, the glass also
contains silica and becomes involved in the reaction. After the test tube has cooled it can be broken
with a gentle blow from a hammer to expose the Mg2Si(s). A mixture of hydrides of silicon,
containing up to six silicon atoms in a chain can then be obtained by tipping the magnesium silicide
into 150 Cm3 of 20% HCl in water. This gives sparkles in dark.

A volcano is an opening on a planet’s surface or crust which allow hot magma, volcano ash and
gases to escape from below the surface. Some well-known volcanoes around the world are Mount
Rainier, USA, Mount Etna, Italy; Mauna Loa, Hawaii, USA; Sakurajima, Japan. A volcano in
Iceland called Eyjafjallajokull erupted in March 2010. It happens when the hot magma finds cracks
on the surface of the planet and forces up or erupts. I made a model using a chemical reaction
between baking soda and vinegar to simulated the gasses and magma flow. When the baking
soda(base) and react with vinegar (acid) it forms the gas, carbon dioxide. The gas expands and
escapes through the opening of the bottle. The gas, flour and food coloring make foam which looks
like the glowing magma in a volcano.
MERCURY BEATING HEART
Vedaang Suresh Krishnan
Department of Chemistry

The Mercury beating heart experiment is a quaint demonstration of the redox principle. A small
drop of mercury (Hg) is placed in a watch glass. The Hg drop is immersed in a solution of dil.
H2SO4 and potassium dichromate. When an iron nail is brought near the Hg drop, a pulsating
motion is observed, resembling a beating heart. The contraction and relaxation of the mercury is
due to changes in the surface tension of, and charge on, the mercury drop. When the mercury is
not in contact with the iron nail, its surface becomes oxidized and the positive mercury ions repel
each other, causing the mercury pool to relax (to lower its surface tension). The relaxation causes
24
the mercury to come into contact with the iron nail, which has a sufficiently negative
electrochemical potential to reduce the mercury ions to mercury metal. The surface tension of the
mercury increases and the pool contracts, causing the contact with the nail to be broken. The
mercury surface reacts with the acid and becomes oxidized again, thereby, completing one cycle
of the oscillation.

The coating or staining of metal is widely used in conductive material preparation. Specifically
silver staining have attracted huge attention due to its applications in
silver printing, lithography, e-textile technologies, wearable
electronics, conductive material preparation and solar applicants.
Only few techniques are reported and used technically to obtain
metallic coating mainly film formation is obtained by staining
material or spray deposition of solution and vapor phase deposition.
These procedures have main drawback that it results into staining over
entire area or fabric, apart from that it requires huge techniques and
high temperature conditions. Thus we have developed a simple law
coast method to obtain staining over substrate in selective
area by modifying sublimation method using phenol
derivative.
The Silver ammine complex solution was added on the substrate (paper and/or cotton), which is
colorless and kept in the center part of sublimation assembly as shown in figure 1. After heating
Sublimated 2,4-di-tert-butylphenol comes into the contact of silver ammine complex, where the
C-C coupling reaction of phenol accurse. The resultant metallic silver stains only selectively over
that area only and results into metallic silver staining, one of the photographs after staining is
shown in figure 2. This coated silver was found chemically stable and conductive in nature, which
is admirable and coast effective.
Ultimately this method has open up the corridor to obtain silver staining which can be useful for
silver printing or lithography in comparative mild conditions, which have main advantage of
selective area staining. To present
it interestingly we have
represented reagent as magical
water. By keeping this paper in
empty assembly due to heating it
results into black silver oxide
formation but by putting it into
another magical assembly
containing phenol results into metallic silver staining over paper.

GRAPHENE-TITANIA NANOCOMPOSITE CONTROLLING AIR POLLUTION Haldankar Shruti Abhijit Chauhan Digant & Parikh Adhwaita
Department of Environmental science
The M. S. University of Baroda, Vadodara 390002
As we all know ‘Graphene’ is our coming future. It is such a material with indigenous properties,
which can be applied to solve several problems and to make existing systems more efficient. Here
is one of its applications. Graphene-titania nanocomposite is a photocatalyst which can convert air
pollutants such as nitrogen oxides, sulphur dioxides, VOCs, etc. into harmless compounds. Air
pollution is becoming a growing worldwide issue. To tackle this problem, a group of scientists
working under the ‘Graphene Flagship’ initiative has developed this nanocomposite, which is
proven to be effective at downgrading at least 70% more NOx than current methods can achieve.
For this purpose, researchers created graphene via the process of liquid-phase exfoliation of
graphite, which they did in the presence of nanoparticles of Titania, and in the absence of any other
materials apart from water. This process formed a new graphene-titania nanocomposite. This
nanocomposite is used to create a coating which can be applied to various surfaces and resulting
into passive photo degradation of air pollutants. In summary, the products of photo degradation
then sit on the coating until they are washed off by wind or rain factors. According to the scientists
working under ‘Graphene Flagship’ project, this nanocomposite is found to be successful at
downgrading 70% more NOx and 40% more rhodamine B (used as a model for volatile organic
pollutants) than current photocatalytic coatings. Graphene-titania nanocomposite was found to be
in powder form and is predicted that this powder can be easily coated on various composite
materials including concrete. Even though this project has some drawbacks but science never stops
further investigations, experiments and research will surely overcome the problems. Ambient air
pollution accounts for an estimated 4.2 million deaths per year due to stroke, heart disease, lung
cancer and chronic respiratory diseases. Around 91% of the world's population lives in places
where air quality levels exceed WHO limits. To change this scenario, we should now walk out
with solution. Hence this project is a big hope to have sustainable development and sustainable
health too.

Importance of patch quality for amphibians is overlooked in distribution models. A study was
carried out to demonstrate relationship between individual species and their microhabitat. The
authors collected data in two monsoon seasons for 21 amphibian taxa from 14 lateritic plateaus.
12 taxa had significant associations with microhabitat. Microhabitat distribution was spatially
structured and driven by climate and human activity. 44 % high elevation taxa were associated
with woody plants while water bodies associated with 67% of low-elevation taxa. Rocks were
important for 3 caecilians. Anthropogenic activities, edaphic and macroclimate affect their
availability. The authors concluded that amphibian distribution varies on plateaus that are
individualistic patches whose habitat quality is defined by their microhabitats. Amphibian
conservation should therefore include preservation of these plateaus.
FOAM IN THE AQUATIC ENVIRONMENT- AN UNSOLVED RIDDLE
Nisha M. Talati and Harsha L R
Department of Environmental Studies
Faculty of Science, The M. S. University of Baroda, Vadodara 390002
Surface water contamination is a serious issue all over the world. Foaming in the streams, rivers,
lakes and sea water is now increasing. They often are assumed to be anthropogenic in origin as
they are aesthetically unpleasant, but they may be indicating a natural origin. Surfactants like
substances from these sources combined with turbulence and water are the main cause of foam
formation. The natural cause of foaming is due to decomposition of algae, macrophytes etc.
Phaeocystis globosa is one such marine phytoplankton that can cause foam in the water bodies.
Untreated discharge of sewage, industrial effluents, and agricultural runoff leads to nutrient
enrichment that triggers foam formation. This foaming has negative impacts like oxygen depletion
in water, affecting aquatic organisms etc. Some solutions to these problems exist but
implementation is less. Not controlling this problem may have unforeseen effects in future.

While analysing the principal topic “Science – an ever-learning platform for better future”, the
first thing that comes to my mind is what purpose does a dynamic field like geography serve
towards new innovations backing science. The most vibrant and ever reformative GIS plays a
key role. And speaking of being an ever-learning platform, what better field to test it around being
one of the most challenging periods of human evolution time, this Covid-19 pandemic. Therefore,
my topic, “Role of Geospatial Technology in Health GIS with the current case study of Covid-
19”. Geospatial technology can be used to overcome the greatest challenge in war against any
disease. The disease surveillance and health information management is one of the important
areas where it is tried to understand the disease related parameters and how the information
systems can be developed. It is said that if disease travels faster, information has to travel even
more faster so because of the geospatial technology all these things can be really taken in a real-
time mode and one can provide lot of solutions in order to eradicate these types of epidemics
INTRODUCTION TO GREENREVOLUTION
Upasani Nandini
T.Y B.Sc., Department of Geography

The Green Revolution in India refers to a period in India when agriculture was converted into an
industrial system due to the adoption of modern methods and technology, such as the use of high
yielding variety (HYV) seeds, tractors, irrigation facilities, pesticides, and fertilizers.
The initiatives resulted in the adoption of new technologies, including high-yielding varieties
(HYVs) of cereals, especially dwarf wheat and rice. It was associated with chemical fertilizers,
agrochemicals, and controlled water-supply (usually involving irrigation) and newer methods of
cultivation, including mechanization.
Although the Green Revolution has been able to improve agricultural output in some regions in
the world, there was and is still room for improvement. As a result, many organizations continue
to invent new ways to improve the techniques already used in the Green Revolution. Frequently
quoted inventions are the system of Rice Intensification, marker-assisted selection, agro ecology,
and applying existing technologies to agricultural problems of the developing world. There were
problems with both perspectives on the green revolution policies. Critics avoided providing
realistic alternatives for solving national food deficits, poor individuals continued to be hungry,
despite the increased supplies.
The green revolution was a change in agricultural practices with secondary social and political
effects. Both industrialized and less-industrialized countries adopted the practices. Almost all
wheat and rice grown today originated in the green revolution.

We are known that the person who protect us and world to the enemy and problems they called as
"HERO”. We are known them and we give respect, honor, award etc. But we forget who is our
real heros.do you know who protect our earth? That is "TREE" who protect us without any
selfness. They are help to reducing heat produced by industries. It’s also filter harmful dust and
gases such as ozone, carbon monoxide and Sulphur dioxide etc. If a tree observed 1 ton of carbon
over its lifespan, it's like erasing 11,000 million of car emissions. One hundred natural tree can
capture up to 100,000 gallons of rainfall per year reduce runoff and filtering water. Plants are
reduced landscape. They are also used for our health and it’s had a different medical property.
According to Morton Arboretum, the since of tree reduced blood pressure, exposure to tree makes
children less stressed.
Without trees survival is almost impossible as there will be no food for animals or for us to it.

The M. S. University of Baroda, Vadodara 390002
The critical development was made independently and almost simultaneously by John Hadley in England and by Thomas Godfrey, a Philadelphia glazier, about 1731. The fundamental idea is to use of two mirrors to make a doubly reflecting instrument—the forerunner of the modern sextant. Box sextant is a small pocket instrument which looks like a sextant enclosed in a box and is 75mm in diameter. Similar to the nautical instrument, it is also used for measuring both the horizontal and vertical angles. Box sextant is a very small and handy instrument which is easy to carry. A sextant is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. Mainly used at sea, the tool is so named because its arc is one-sixth of a circle – 60 degrees. It adheres to the principle of double reflection hence it can measure angles up to 120 degrees.

Cyclicity is the whole of erupted materials, inside volcanic structure, which are generated during
one volcanic activity period, and is generally formed through the erupted volcanic rocks overlaid
from several edifices and sedimentary rocks between different volcanic Edifices. The volcanic
eruption-cyclicity framework is under magma-migration joint control, evacuation and filling in of
magma chambers, reflecting the entire volcanic activities, process from starting time to peak time,
then into recession time and dormant time. The thickness variation and framework spatial
geometrical shapes are related to the volcanic eruption mode and the eruption center position. The
thickness of the high value zone shows that the eruption center is near and the eruption has large
scale characteristics high frequency long lastic time and an abundant supplement of eruption
material. The low value zone shows a long distance far from the eruption center, the eruptive
material supplement is relatively poor, the rock thickness is low and is in depression area between
volcanic edifices. Framework shapes represent volcanic eruption modes and volcanic rock spatial
distribution patterns, generally under the fracture-eruption type the formed volcanic stratum is
independent or is bead spread along fault belts, which shows cone shape apparent features, moundy
shape and strata thickness varies greatly.
FLOODS IN BARODA

A flood is an overflow of water that submerges land that is usually dry.Flooding may occur as an
overflow of water from a water body such as a river, lake or an ocean, in which the river overtops
or breaks the levees, resulting in some of the water escaping its usual channels. It may also occur
due to the accumulation of rainwater. Floods can occur in rivers when the flow rate exceeds the
capacity of the river channel. Floods cause damage to life and property, particularly in flood plains.
In Vadodara, a city in Gujarat India, floods are a common phenomenon in monsoon. Majority of
the in this city are caused on the VISHWAMITRI river which is a tributary of river DHADAR. A
very recent example of such event is the 2019 Vadodara flood.
Due to heavy rainfall in the month of July and August, Vadodara city and the surrounding districts
were severely affected. The resulting flood took a toll on several lives. Various economic sectors
were hindered because of the same. The schools and colleges were shut for 2-3 days. The low-
lying areas of the city such as SAYAJIGUNJ, AKOTA and PARSHURAM BHATTA were almost
submerged under 10 fts. of water. The transportation facilities were interrupted, including public
and private transports. Electricity supply was interrupted for 48 and many people faced life
challenging situations.
32
To conclude, floods are such catastrophic events that can cause major economic setback to the
affected areas. Hence, flood preventions and mitigation strategies should be set up to avoid all the
above losses.

Disaster Management refers to the conservation of lives and property during natural or manmade
disasters. Disaster management plans are multi-layered and are planned to address issues such as
floods, hurricanes, fires, mass failure of utilities, rapid spread of disease and droughts. India is
especially vulnerable to natural disasters because of its unique geo - climatic condition, having
recurrent floods, droughts, cyclones, earthquakes, and landslides.
33
As India is a very large country, different regions are vulnerable to different natural disasters. For
example, during rainy season the peninsular regions of South India is mostly affected by cyclones
and states of West India experience severe drought during summer.
The steps being taken by the Government emanate from the approach has been outlined above.
The approach has been translated into a National Disaster Framework (a roadmap) covering
institutional mechanisms, disaster prevention strategy, early warning systems, disaster mitigation,
preparedness and response, and human resource development. The expected inputs, areas of
intervention and agencies to be involved at the National, State and district levels have been
identified and listed in the roadmap.
This roadmap has been shared with all the State governments and Union Territory Administrations.
Ministries and Departments of the Government of India and the State Governments/Union
Territory Administrations have been advised to develop their respective roadmaps taking the
national roadmap as a broad guideline. There is, therefore, now a common strategy underpinning
the action being taken by all the participating organizations/stakeholders.
DRAINAGE SYSTEM OF INDIA

T.Y. B.Sc., Department of Geography
The M. S. University of Baroda, Vadodara 390002
1. The Indian Drainage System is divided into 3 categories: (1) Major River Basin with
catchment area up to 20000 sq. km. and above, accounts for 83% of the total run off and
are 13 in number in India. (2) Medium River Basin with catchment area of 2000-20000
sq. km. and above accounts of 8% of the total run off all the rivers and are 45 in India. (3)
Minor River Basin with catchment area up to 2000 sq. km. It accounts for 9% of the total
run off among all the rivers with 55 basins in India.
2. On the basis of physiographic origin, the Indian drainage may be distinguished as the
Himalayan drainage and the peninsular drainage. Himalayan drainage system mainly
comprises the basin areas of the Indus, the Ganga and the Brahmaputra. These are mostly
perennial and youth having gorges, V-shaped valley and depositional like Deltas
3. Many of the rivers are older than the Himalayas and cut across it. Whereas Peninsular
Rivers is much older and includes numerous rivers. Rivers are matured with almost graded
Profiles and mostly superimposed in nature i.e., follow the gradient or fault valley. These
are devoid of meanders and have fixed course unlike Himalayan drainage.
4. River Indus flows through Ladakh and Zaskar Range. Gilgit is a right bank tributary of
Indus.
5. Ganga River enters into plain at Haridwar. The number of tributaries of the River Ganga
is more in Avadh Plain as compared to that in Rohilkhand Plain. Bhagirathi and Alaknanda
meet at Devprayag and after that it takes the name of river Ganga.
6. Brahmaputra or Tsangpo flows through Tibet, India and Bangladesh and forms the largest
delta of the world along with Ganga.
7. Important tributaries are Subansiri, Kameng, Dhansiri, Dihang, Lohit, Tista, Manas, etc.
River Brahmaputra is called as Sikiang in Arunachal Pradesh and Jamuna in Bangladesh.
34
8. East flowing rivers of Peninsular India are Mahanadi, Godavari, Krishna and Cauvery and
West flowing rivers are Narmada, Tapi, Mahi, Kalinadi and other small rivers.
9. Mahanadi originates from Sihawa North foot hills of Dandakarnaya. Godavari originates
from Trimbak Plateau of North Sahyadri near Nasik and Godavari makes boundary
between Maharashtra and Andhra Pradesh.
10. Krishna originates North of Mahabaleshwar in the Western Ghat and along with Godavari
it forms the 2nd largest delta in India. Koleru Lake lies in this delta.
11. Cauvery rises in Brahmagiri Range in Western Ghat. This is the only Perennial River in
Peninsular India and creates contention among Kerala, Tamil Nadu, and Karnataka.
Cauvery forms a quadrilateral delta at its mouth.

Definition: - A Volcanic Eruption occurs when magma is released from a volcano. Volcanic
eruptions can be quite calm and effusive, or they can be explosive.
A Volcanic Eruption occurs when hot materials from the Earth’s Interior are thrown out of a
volcano.
For example:
In 2020, erupting volcanoes included Taal Volcano in the Philippines, La Cumbre in the
Galapagos, Mount Shishadin in Alaska, Pacaya Volcano in Guatemala, Mount Semeru and Mount
Sinabung in Indonesia, Piton de la Fournaise on Réunion Island, Mount Etna in Sicily.
• CAUSES OF VOLCANIC ERUPTION
Major causes of volcanic eruption:
- Tectonic movement.
- Sea floor spreading.
- Earthquake.
- Tsunami.
- Subsurface magma movement.
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing
substance called Magma. Since it is lighter than the solid rock around it, Magma rises and collects
in magma chambers. It is a geological event where the magma erupts from the Earth’s events. This
occurs due to the Earth’s Internal Energy sourced from three things.
- Radio Activity of heavy material within the Earth’s Crust.
- Due to Earth’s Gravitational Energy converted into Heat Energy.
35
- Primordial Solar Energy (Energy trapped interior of the Earth)
1). Disintegration of radioactive elements deep within the earth bed causes the heated rock to take
the shape of molten lava.
2). Origin of Magma because reduction in the pressure due to splitting of plates and their
movement in different direction.
3). Origin of gases and vapor due to heating of water which reaches underground through
percolation of rain water and snow melt water.
• BENEFITS OF VOLCANIC ERUPTION.
1. Volcanic materials ultimately break down and weather to form some of the most fertile
soils on Earth, cultivation of which has produced abundant food and fostered civilizations.
2. The Internal heat associated with young volcanic systems has been harnessed to produce
geothermal energy.
3. Most of the metallic minerals mined in the world – such as gold, silver, copper, lead and
zinc are associated with magmas found deep within the roots of extinct volcanoes.

Solar energy is good renewable source for our society. It is essential source of renewable energy.
Active solar technique includes the use of photovoltaic systems, concentrated solar power, solar
water heating. Solar power is conversation of sunlight into electricity. In U.S. has some of the
richest solar resources in the world. And also, Gujarat state is the top in India for domestic rooftop
solar installations. Gujarat has already achieved 11,000 MW of production capacity and has set a
target of producing 30,000 MW of green energy by 2022, which will largely include wind and
solar energy. Moreover, Gujarat has successfully implemented the Solar Rooftop Scheme and is
currently generating around 800 MW of solar energy from it. In 2017 the international energy
agency showed that solar had become the world's fastest growing source of power Solar energy
more useful than all other source of energy. Solar energy helpful for clean economy, reduce
electricity bill, low maintenance costs. It is reduced pollution and clean environment we use
electric vehicles charge through solar power so maintain pollution. Why the government increase
a cost of fuels? because government think when more people use electric vehicles and control the
level of pollution.

The desire of sustainable development is not new. Humans are constantly finding ways that leads
to sustainable living. With this, the concept of green houses became popular. But these types of
savings are not enough. We have to go beyond and study our nature and earth more precisely. It is
evident that whenever humans moved against nature, it always ended with huge losses. For
instances, poor town planning invites many disasters. Infrastructures without proper planning and
execution are now the prime factors of increasing health problems. Therefore, it’s a high time we
need to spend time to understand earth.

Arsenic is a natural component of the earth’s crust. It exists in the form of oxides in the soil,
sediments, and water. It is highly toxic in its inorganic form and causes Arsenicosis including
pigmentation changes, skin lesions, hard patches on the palms and soles of the feet
(hyperkeratosis), and eventually results to skin and bladder cancer. Arsenic contamination in
groundwater is one of the most major challenge faced by humankind. The groundwater of at
least107 countries are arsenic affected. In India, the states of West Bengal, Bihar, Jharkhand, Uttar
Pradesh, Assam, Manipur and Chhattisgarh are reported to be most affected by arsenic
contamination of groundwater above the permissible limit (10 ppb), i.e. regions along the parts of
Gangetic and Brahmaputra river plains are severely affected because of natural cause, mostly
concentrated to eastern and few north-eastern parts of India.It also depends upon local geological
factors and human activities such as irrigation and disposal of industrial chemical wastes to water.
Therefore, it becomes necessary to treat Arsenic for the safe consumption of water. Looking to the
shortcomings of existing technologies for Arsenic mitigation, we develop an Arsenic Filtration
Unit based on magnetic treatment of Arsenic (along with other metallic contaminants) from water
by applying magnetic field which performs with maximum efficiency and sustainability, minimum
consumption and infrastructure without wasting single drop of water. It’s easy to operate &
maintain, and is affordable & reachable to every section of community with best quality of drinking
water.

The sun is the source of most energy on the earth and is a primary factor in determining the thermal
environment of a locality. The challenge about technical consideration on the effect of solar
radiation could be as a result of incompetency of the engineers that may not be able to make
estimates of solar radiation intensity and know how to make simple solar radiation measurements.
It could also be that the instruments that are used for solar radiation measurement are not accurate
thereby leading to a false result.
The main aim of the study is to examine technical consideration of the effect of solar radiation.
Other specific objectives of the study include;
1. to determine the extent to which technical radiation affects solar radiation in Nigeria.
2. to determine the impact of technical consideration on solar radiation in Nigeria.
38
3. to determine the factors affecting technical consideration on solar radiation in Nigeria.
4. to proffer possible solutions to the problems
The study on the technical consideration of the effect of solar radiation will be of immense benefit
to the entire Nigeria in the sense that it will enable the solar technical engineers to be well equipped
in order for them to be able to handle challenges of any sorts that has to do with solar radiation.
The study will also educate the government to be fully aware of the kind of people they employ
into this sector for the benefit of the citizens in the country. Finally, the study will contribute to
the body of existing literature and knowledge to this field of studies and basis for further research.
THE SHRINKING OF ARAL SEA (DESCRIPTION, HISTORY, DEMISE, & FACTS)

Aral Sea is a huge terminal lake which is located in the desert of Central Asia. This lake has
repeatedly filled and dried due to both natural and human causes over the past 10 millennia. Aral
Sea has gone through a drastic shrinkage during the past century, from more than 68,000 km2 in
1960s to less than 10,000 km2 in 2015. The desiccation was highly severe in 2009 and 2014 due
to the west basin changed to an exposed bottom for several months. The Aral Sea depression was
formed toward the end of the Neogene Period (which lasted from about 23 to 2.6 million years
ago). The Aral Sea area is characterized by a desert-continental climate that features wide-ranging
diurnal air temperatures, cold winters, hot summers, and sparse rainfall. The rate of precipitation—
an annual average of 4 inches (100 mm) in all, occurring mainly in the spring and autumn—is only
a tiny fraction of the lake’s traditional rate of evaporation. The rapid shrinkage of the Aral Sea led
to numerous environmental problems in the region. The salt and mineral content of the lake rose
drastically because of that, making the water unfit for drinking purposes and killing off the once-
abundant supplies of sturgeon, carp, barbell, roach, and other fishes in the lake. The fishing
industry along the Aral Sea was thus virtually destroyed.

Agriculture is an important sector of Indian economy. More than 50% of the rural households
depend on agriculture. It contributes about 17% to the total GDP and provides employment to
over 60% of the population.
In recent day satellite based optical Remote Sensing images are widely used in the monitoring of
agriculture. It uses visible, near infrared and short-wave infrared sensors. Optical bands are very
helpful in the identification of crop land. Vegetation indices like NDVI, EVI, SVI etc. arc widely
used method for identification of crop. In the optical Remote sensing NIR band (0.85 – 0.88 μm),
Red band (0.64 – 0.67 μm) and sometimes Green Band (0.53 - 0.59 μm) are very useful band for
the crop identification.
In this study an attempt has been made to identify the crop type using Supervised Maximum
Likelihood Classification with the help of training data of the crop type. For this analysis NIR
band of Sentinel Satellite Images was used. The area under study was Bara Tract region, Bharuch
district. The main crop of this region is cotton and tur. Analysis of the results states that the overall
classification accuracy of the method was satisfactory. The highest accuracy was found in cotton
crop whereas the lowest accuracy was found in tur crop.

regulating the global carbon budget but because of the degradation the global carbon budget has
been disturbed. Amazon rainforest plays an important role in stabilizing global climate and rainfall.
INTRODUCTION TO CARBON FOOTPRINT

T.Y. B.Sc
Department of Geography

A carbon footprint is the total amount of greenhouse emissions that result directly and indirectly
either from an individual's lifestyle.
Carbon footprints can be reduced through improving energy efficiency and changing lifestyles and
purchasing habits. Switching one’s energy and transportation use can have an impact on primary
carbon footprints. For example, using public transportation, such as buses and trains, reduces an
individual carbon footprint when compared with driving.
Individuals and corporations can reduce their respective carbon footprints by installing energy
efficient lighting, adding insulation in buildings, renewable energy sources to generate the
electricity they require. For example, electricity generation from wind power produces no direct
carbon emissions. Additional lifestyle choices that can lower an individual’s secondary carbon
footprint include reducing one’s consumption of meat and switching one’s purchasing habits to
products that require fewer carbon emissions to produce and transport.
Large carbon foot prints deplete resources on large and small scales, from a country’s
deforestation. Activities to one home increased use of air conditioning. The more those with large
carbon footprints use resources, the more greenhouse gases increase and spur further climate
change.
Carbon emissions affect the planet significantly, as they are the greenhouse gas with the highest.
Levels of emissions in the atmosphere. This, of course, causes global warming and ultimately,
climate change. This warming causes extreme weather events like tropical storms, wildfires, severe
droughts and heat waves.

GLOBAL WARMING
Dashrath Luva
Department of Geography
The M. S. University of Baroda, Vadodara 390002
Global warming is the cumulative rise in average global temperatures on earth Measured over a
long period. It has been attributed to the large-scale deforestation by Man for different purposes.
We consume a lot of fuel annually. With an increase in the Human population, it has become
impossible to meet people’s fuel requirements. Natural resources are limited, and we must use
them judiciously. If we exploit natural resources like forests and water bodies, it will create an
imbalance in the ecosystem. Global warming is not limited to the rise in temperature. It has other
effects too. Many parts of the world are witnessing natural disasters like hurricanes, floods, and
Avalanches. All these phenomena are a direct result of global warming. To prevent our
Environment from the harmful effects of global warming, we must restore us Ecosystem. Man has
been exploiting natural resources without giving the environment anything in return. This needs
to be stopped. We must all join forces to make this world a better place for our future generations
who deserve this planet as much as we do. The basic step that we can follow to increase the overall
health of our planet is planting trees. Afforestation should be our primary goal. The earth can
become a better place if we pledge to plant as many trees as we can in our lifetime.
GLACIER STUDIES USING REMOTE SENSING DATA

In the recent years, the Himalayan glaciers have acquired a lot of value as they play a significant
and active part in the climate change scenario. As a result, it has become crucial to preserve the
repository of these strong freshwater resources in the form of the Digital Glacier Inventory.
Using Resourcesat-1 satellite data, a systematic inventory of all the glaciers in the Eastern
Himalayan region covering the north-eastern state of Sikkim and the Kingdom of Bhutan was
carried out on a scale of 1:50,000. Geocoded satellite data at the end of the ablation season (July
to September) was used to map the glacial features using FCC (False Colour Composite) with
standard band combination 2 (0.52-0.59 µm), 3 (0.62-0.68 µm) and 4 (0.77-0.86 µm) and
additional SWIR band 5 (1.55-1.70 µm). The tabular glacier inventory data sheet was designed in
the GIS environment to provide insight into parameters such as glacier location, dimensions,
elevation, moraine dammed lakes, supra glacial lakes, etc. To understand the characteristics of the
glacial systems, intra basin level analysis of glacier inventory data was carried out.
An insight into the behavior and overall health of the glaciers can be provided by critical review
of the glacier inventory data. Glaciers with a higher accumulation area are said to be more stable,
since even after summer melt, glaciers have an immense volume of water preserved within them.
Similarly, glaciers with more debris serves as a shielding layer against glacier melt. Therefore, the
region under study had large areas of accumulation and large debris areas, thereby contributing to
the glaciers' good health. For both the areas under study in the Eastern Himalayan Region, the
general orientation of the glaciers, independent of the geographic distribution, was north-east and
east.
HOW SCIENTISTS CAPTURED THE FIRST IMAGE OF A BLACK HOLE
Suthar Jaymin
Department of Geography
The M. S. University of Baroda, Vadodara 390002
Scientists have obtained the first image of a black hole, using Event Horizon Telescope
observations of the center of the galaxy M87. The image shows a bright ring formed as light bends
in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun.
Though scientists had theorized they could image black holes by capturing their silhouettes against
their glowing surroundings, the ability to image an object so distant still eluded them. A team
formed to take on the challenge, creating a network of telescopes known as the Event Horizon
Telescope, or the EHT. They set out to capture an image of a black hole by improving upon a
technique that allows for the imaging of far-away objects, known as Very Long Baseline
Interferometry, or VLBI.
Telescopes of all types are used to see distant objects. The larger the diameter, or aperture, of the
telescope, the greater its ability to gather more light and the higher its resolution (or ability to
image fine details). To see details in objects that are far away and appear small and dim from Earth,
we need to gather as much light as possible with very high resolution, so we need to use a telescope
with a large aperture.
43
That’s why the VLBI technique was essential to capturing the black hole image. VLBI works by
creating an array of smaller telescopes that can be synchronized to focus on the same object at the
same time and act as a giant virtual telescope. In some cases, the smaller telescopes are also an
array of multiple telescopes. This technique has been used to track spacecraft and to image distant
cosmic radio sources, such as quasars.
The aperture of a giant virtual telescope such as the Event Horizon Telescope is as large as the
distance between the two farthest-apart telescope stations – for the EHT, those two stations are at
the South Pole and in Spain, creating an aperture that’s nearly the same as the diameter of Earth.
Each telescope in the array focuses on the target, in this case the black hole, and collects data from
its location on Earth, providing a portion of the EHT’s full view. The more telescopes in the array
that are widely spaced, the better the image resolution.
To test VLBI for imaging a black hole and a number of computer algorithms for sorting and
synchronizing data, the Event Horizon Telescope team decided on two targets, each offering
unique challenges.

The relation between man and his surrounding is continuously changing. It is extremely important
and interesting to cohere the natural changes to other fields of study. To observe, learn and apply
this natural change for mankind, curriculum setters have included ‘field survey’ as one important
aspects of Geography. There are different methods and tools for field survey. There should be prior
planning before proceeding towards selected field. Topographical map, geology, geomorphology
and agricultural geography are some of the important areas for field survey. There are different
methods and tools to carry out field survey. Prismatic compass, Theodolite, Dumpy level or spirit

Deforestation is the permanent removal of a trees to make room for something besides forest. This
can be include clearing the land for agriculture and grazing or using the woods for a fuel,
construction or manufacturing and other causes like mining, forest fires, overpopulation etc.
Forests cover more than 30% of the Earth’s land surface but they are disappearing at an alarming
rate. These forested areas can provide food, medicine and fuel for more than a billion people.
Worldwide, forests provide 13.4 million people with jobs in the forest sector.
44
Today most deforestation is happening in the tropics. Areas that were inaccessible in the past are
now within reach as new roads are constructed through dense forests. The World Bank estimated
that about 3.9 million square miles of forest have been lost since the beginning of the 20th century.
The Guardian reported that every second, a chunk of forest equivalent to the size of the soccer
field is lost. Forests can be found from the tropics to the high-latitude areas. They are home to 80%
terrestrial biodiversity, containing a wide array of trees, plants, animals, and microbes. They are
also an important resource for many living species around the World. Trees also absorb carbon
dioxide, mitigating greenhouse gas emission produce by human activities. We need trees for a
variety reasons not least of which is that they absorb not only the carbon dioxide that we exhale
but also heat trapping greenhouse gases that human activities emit. Many effects of deforestation
like climate change, increasing in Green house gases, soil erosion, floods, loss in bio-diversity.
The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and
laws to govern it. Reforestation and Afforestation is also a good solution, last skinned of its tree
cover for urban settlements should be urged to plant trees in the vicinity and replace the cut trees.
Reducing in a usage of paper is also a solution or use recycled paper and finally educate others
because still many are entirely unaware of global warming problem Educate community by sharing
the deforestation facts. indeed “Save trees, save life”.

Water cycle is one of the most important processes in the world. Describe the storage
and movement of water between the: Biosphere, Atmosphere, Lithosphere, and Hydrosphere. The
Water cycle is composed of the following components: Evaporation, Transpiration, Sublimation,
Condensation, Precipitation, Run-Off, Infiltration and percolation, and Ground water. Process of
Hydrological cycle start with ocean water in oceans, gets evaporated dye to heat energy provided
by solar radiation and forms water vapor. This water vapor moves upwards to higher altitudes
forming clouds. Most of the clouds condense and precipitate in any form like rain, hail, snow,
sleet. A part of cloud is driven to land by winds, precipitation while falling to the ground, some
part of it evaporates back to atmosphere. Portion of water that reaches the ground, enters the earth’s
surface infiltrating various strata of soil and enhancing the moisture content as well as water table.
Vegetation sends a portion of water from earth’s surface back to atmosphere through the process
of transpiration. Once water percolation and infiltrates the earth’s surface, runoff is formed over
the land, flowing through the contours of land heading towards river and takes and finally joins
into oceans after many years. Some amount of water is retained as depression storage. Further
again the process of the hydrological cycle continues by blowing into water vapor then clouds
getting condensed and precipitates as rain fall. Similarly, then water gets percolated into soil,
increasing water table then formation of runoff waters heading forwards water bodies thus the
cyclic process continues. The Hydrological cycle is important because it is how water reaches
plants, animals and us! Besides providing people, animals and plants with water, it also moves
things like nutrients, pathogens and sediment in and out of aquatic ecosystems.

Science has made immense contribution in uplifting human society, filling our minds with
knowledge and intelligence. It helped us notice the marvels of mother nature to which we were
previously oblivious. It also reminded us that we are just an infinitesimally small part of this ever-
expanding universe. Right from invention of wheels to building a supercomputer, science has made
our lives easier while we enjoy the comfort of everyday life. Below are few of the many areas
where science has played an important role
Preventing Outbreak of Deadly Diseases In early 14th century, ‘plague’ wiped out nearly a third
of entire human population. In 2009, a similar pandemic called ‘swine flu’ was brought under
control before it could cause significant damage (Source: Wikipedia). Even diseases such as
cancer, HIV are curable when detected in early stage. Reason: Advancement in medical
technology, Availability of medical facilities, Improved disease prevention mechanism like
vaccinations.
Pandemic (H1N1) 2009
Early warning against Natural Disasters
In 1999, super cyclone ‘05B’ lashed the east Indian state of Orissa killing more than 15000 people
and leaving an estimated 1.5 million people homeless with damages amounting $4.4 billion. It was
the strongest cyclone ever recorded in the north Indian ocean with wind speed reaching 260 kmph
(Source: Wikipedia). After 13 years a similar cyclone hit Orissa, but this time the casualties were
close to 40. How did India manage to reduce this number?
Reason: Improved weather forecasting from Remote sensing and meteorological satellites
launched after 1999 helped in developing an early warning system.
How India went from 15,000 cyclone deaths in 1999 to just 38 last year Uninhabitable lands turned
into modern day Oasis. Although 71% of Earth’s surface is covered with water, less than 1% is
drinkable and not every available land on earth is cultivable. However, desserts of middle east with
the dry and hot climatic conditions have managed to become global finance and tourism hubs.
These gulf countries with depleting water resources have installed several desalination plants to
tackle and prolong impending water crisis. Moreover, countries like Israel have managed to turn
their barren lands into productive fertile agricultural fields that feeds millions of people. Reason:
Innovation in the field of Agriculture, Improved crop storage facilities, Water harvesting
techniques.
For UAE, hope in deep ocean water desalination
12 top ways Israel feeds the world Science has become an integral part of our existence. Moreover,
in the 21st century it is more embedded into our life than it was ever before. It has made things
easier for us by providing comfort and security. But does it mean we can’t survive if someday we
are thrown back to the stone age? Yes, we most certainly can because that’s what our ancestors
did thousands of years ago and they lived a happier life even before the advent of science. So,
Science has a important role but there is more to life than science itself.

The Maharaja Sayajirao University Of Baroda
A Volcano is a rupture in the crust of a planetary mass object, such as
Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the
surface. On Earth, volcanoes are most often where tectonic plates are diverging or converging, and
most are found underwater.
Strictly speaking there are two broad types of Volcanoes:-
a stratovolcano and a shield Volcano, although there are lots of volcanic features that can form
from erupted magma ( such as cinder cones, or as lava domes ) as well processes that shape
volcanoes.
REMOTE SENSING APPLICATIONS USING IN AGRICULTURE
Ramjiyani Drashti Laxmichand and Shaikh Nameera Sulemanbhai
Department of Geography, Faculty of Science
What is remote sensing applications?
Remote sensing is the process of acquiring information, detecting, analysing, and monitoring the
physical characteristics of an area by recording. It is reflected and emitted radiation energy
without having any physical contact with the object under study. This is done by the capturing
the reflected radiation energy.
☆ Applications of remote sensing in agriculture
1 Identifying crop conditions => satellite imagery and normalized difference vegetation index
NDVI technologies are used in order to monitor global food supplies. Healthy crop area reflects
green whereas other areas reflect red and blue.
2 Increasing precision farming => The health of crops can be measured using remote sensing
applications.
3 Determining the soil moisture content => Active and passive sensor of a satellite in space are
used in order to determine the soil moisture content.
4 water content determination of the field crop => Apart from determining the soil moisture
content.
49
As per upper applications remote sensing are very useful in agriculture nowadays, as we know in
India 70% livelihood is based on agricultural activity and it contributes 35 % of the net national
product. Remote sensing can provide valuable information for land and water management.
Knowledge of food grains production before harvesting, helps country to manage shortage,
buffer stock, imports and fixing of support price.
As we know nowadays technology is overcome in every sector, by using technology our work
became easier. Currently under FASAL (forecasting agricultural output using space agro
meteorology and land based observations) project, national state level multiple forecasts are
being issued for 5 crops – rice (kharif – rabi ) jute rapeseed and mustard winter potatoes and
wheat. Precision farming is an integration of various technologies such as RS, GPS,GIS and field
equipment. By this way we use RS applications to get better future for farmers and steps
towards a developed nation.

The Maharaja Sayajirao University of Baroda.
We all are aware about the atmospheric layers of the earth but what do we know about the
interior of the earth? In the video, the earth’s internal structure is explained that involves the
discussion on three principal layers of the earth. The first and outermost layer of the earth, the
‘crust’ is thinnest of all and has the lowest density. The second layer, ‘mantle’ is in molten state
which is composed of silicate rocks that are rich in iron and magnesium. The innermost layer,
‘core’ has a composition of iron and nickel in general. Core is further divided into inner core and
outer core that are in solid and liquid states, respectively. The video also throws light on how
these layers are discovered.

Faculty of Science,
Rocks! We generally find the rocks all around us. In earth science, the rocks are considered to be
of most importance since they are the geologists’ clock to infer the earth’s history. In the video,
three main type of rocks are discussed with respect to their origin, namely, igneous, sedimentary
and metamorphic. Rock cycle is one of the fundamental concepts of geology that explains the
transition between three basic type of rocks given above. Igneous rocks are considered as
primary rocks. They are formed from the crystallization of magma and lava. They are divided
into two sub-categories viz. plutonic igneous rocks and volcanic igneous rocks with respect to
their depth of formation. Sedimentary rocks are secondary rocks that are formed when sediments
broken from primary rocks on account of weathering and erosion are bound by natural cement
and lithified further. The third basic type of rocks is metamorphic, yet they are not considered as
tertiary kind of rocks! Metamorphic rocks can be formed either from igneous or sedimentary
rocks. Here, the processes and agents that are responsible for the formation of all three type of
rocks are discussed. The formation of these basic type of rocks is the endless cycle that goes on.
Hence, A ROCK CYCLE!

The applications of single and multiple integration in real life are described by considering their
few examples in our routine life. In the first section, the applications of single integration in various
fields are given. The procedure of calculating the area of a circular garden using integration is
described. In general, the process of calculating the area of any curved land using integration is
described. The fabric required for making a designer masterpiece can be guessed using the process
of integration and hence the approximate cost of the fabric can be obtained.
In the second section, it has been shown that how use the of double integration simplifies
the task of computing the areas of different regions and finding the volume of a solid bounded by
a specific region. The use of the integration in modern architectures is also given.

The objective of this presentation is to emphasize the importance of The Pigeonhole Principle. It
was published by Peter Gustav Dirichlet in 1834, but was used since the early 1600s. In the video,
we show that it is an intuitive concept that is easy to understand. The concept, while being one of
the simplest ideas, is applied to many different areas of Discrete Mathematics and is a crucial
proving technique. To demonstrate this, we first ask the question: If we select any five natural
numbers, will we find a pair of numbers whose difference is divisible by a number less than five,
say the number four? We wanted to explain that if you consider n objects (pigeons) and distribute
them among n-1 containers (pigeonholes), then we will always find one container with at least two
objects. To explain the basic idea of this principle, we approached an easy example in three ways.
First, we picked three random cards from a deck and observed that at least two cards were of the
same colour. Second, we picked five random cards, considered the suit and reached a similar
conclusion. Finally, we observe the suit when picking 10 random cards. This leads to the general
definition of the the Pigeonhole Principle. We revisit the aforementioned applications and explain
the steps that lead to our final result. Lastly, we address our initial question of selecting any 5
natural numbers and also explain it in a general form with the intention to show an indirect
application of The Pigeonhole Principle.

We can easily find the area of closed shape made up of straight lines using triangle & square which
is known to us. But we can’t use this in general for finding area of a curved shape. So in this video,
we will see how to find the area of curved shape. The idea for this comes from the concept of limit.
This also involves Calculus (a branch of mathematics) and integration. We will use method of
exhaustion for finding area of circle with the help of a regular polygon. Similarly, for parabola, we
will use triangle shape. Every time it is difficult to find such a shape, so that our shape is exhausted.
So, we should find a general shape for this. Rectangle plays a vital role in this.

We have a square cardboard. Our goal is to make a box from this by cutting square from each
corner such that the volume of the box is maximum. For this, we will form a function for volume
of the box and our aim is to maximize it. From calculus , we know the method to find a value of
variable for which the function attains maximum or minimum value. For 60x60 square cardboard,
we will use this to find the square to be removed from each corner so that the volume of the box
obtained is maximum.

KAPAREKAR’S CONSTANT NUMBER
Parmar Jaydip
Department of Mathematics,
The M.S. University of Baroda, Vadodara 390002.
We chose any four digits number. For example, we take 𝟖𝟎𝟏𝟓.Then we write this number’s digit
in decreasing order. So, we get 𝒂𝟏 = 𝟖𝟓𝟏𝟎 and similarly we write this number in increasing order
we get 𝒃𝟏 = 𝟎𝟏𝟓𝟖. Then we take difference 𝒂𝟏 − 𝒃𝟏 = 𝟖𝟑𝟓𝟐. Similarly, in this way we get
𝒂𝟐 = 𝟖𝟓𝟑𝟐 and 𝒃𝟐 = 𝟐𝟑𝟓𝟖. And 𝒂𝟐 − 𝒃𝟐 = 𝟔𝟏𝟕𝟒. Similarly, we get 𝒂𝟑 = 𝟕𝟔𝟒𝟏 and 𝒃𝟑 =𝟏𝟒𝟔𝟕 and 𝒂𝟑 − 𝒃𝟑 = 𝟔𝟏𝟕𝟒. We notice that 𝟔𝟏𝟕𝟒 is repeat. The number 𝟔𝟏𝟕𝟒 known as
kaparekar constant number. He was an Indian mathematician.
The number of the type 𝟒𝟐𝟎, 𝟑𝟐𝟏, 𝟐𝟐𝟐, 𝟏𝟐𝟑, 𝟎𝟐𝟒 for e.g., 𝟒𝟐𝟎 type means we get 𝒂𝟏 = 𝒂𝒃𝒄𝒅
and 𝒂 − 𝒃 = 𝟒, 𝒃 − 𝒄 = 𝟐, 𝒄 − 𝒅 = 𝟎. We reach the kaparekar numbers directly one step of the
above process by the above type numbers.

Puzzles can be regarded as problem-solving games. It enhances the problem-solving ability and
logical thinking.
(1) Finding the missing number/word:
The logic behind this type of puzzle is that the numbers are arranged in a particular sequence and you
have to identify that sequence. In this method students practice their addition,
subtraction, multiplication and division skills by searching for hidden math equations. It can be
adapted to any skill and promotes a solid understanding of basic math facts.
(2) Matchstick type puzzle:
This type of puzzle seems simple, but it just might stump you. After setting up sticks in the required
order, challenge is to make it as a given shape by moving just few matchsticks.
(3) Join the dots:
This puzzle challenges students to connect all the dots using only some straight lines. Here the
challenge is that you can use only a few straight lines.
(4) Counting squares:
In this type of puzzle, you have to count all possible squares. i.e. to count from the grid 1x1 to n x n.
62
Math puzzles allow students to develop foundational skills in a number of key areas, and can influence
how students approach math practically and abstractly. You can also tie them into strategies.

This video is based on the mathematics in the Rubik’s cube. This Rubik’s cube is made by an
engineer, Erno Rubik. It has 6 sides with 9 individual pieces on each. This cube has total 43
quintillion possible positions and only one is the correct one. In this Rubik cube there is a
involvement of group theory. In the case of the Rubik’s cube, the elements are the faces of the toy.
To be called a group, the elements satisfy all the four properties of group i.e., Closure, associativity,
identity, inverse properties. Therefore, elements of Rubik’s cube form a group. Infact, they form a
permutation group. And since it is a permutation group, it is not a commutative group. The Rubik’s
cube can be connected to fractions, ratios, and proportional reasoning for the school level of
understanding.

Organoids derived from stem cells or tissues in culture can develop into structures that resemble
the in vivo anatomy and physiology of intact organs. Organoids are generally used to study human
disease models, drug development and drug testing. The liver is a vital organ essential for digesting
food and removing toxic substances from the body. The liver is susceptible to many life-
threatening diseases and many of which are inherited. Liver problems can also be caused by a
variety of factors like viruses, alcohol use and obesity. Over time, conditions that damage the liver
can lead to cirrhosis, which can lead to liver failure, a life-threatening condition. Liver organoids
are now being established for multiple species from induced pluripotent stem cells, embryonic
stem cells, hepatoblasts, and adult tissue derived cells. “Liver medicine” refers to all the diagnostic
and treatment strategies of the disease that cause liver failure directly or indirectly. Effective liver
medicines are needed for some of the liver diseases that provide more effective therapeutic
advantages to patients. Despite significant advances in the field of liver medicine, improved tools
are needed for some of the liver disease. Liver organoids facilitate drug testing and personalized
therapy. Next generation cell culture system has immense potential to be further improved by
genome editing and bioengineering technologies to encourage the development of patient specific
therapeutic options for clinical applications.
ARE WE READY TO EAT LIVE MICROBES?
Afiya Shaikh, Kajal Acharya and Tuhina Bhattacharya
Department of Microbiology and Biotechnology Centre,
The M. S. University of Baroda, Vadodara 390002
Microorganisms have been used as food and fodder for centuries. Saccharomyces cerevisiae
(Baker’s and Brewer’s yeast) has been used in fermentation to make alcoholic beverages by the
64
ancient Egyptian civilizations, and by the Germans as an edible protein source during World War
II. Algae have supported the lives of historic communities living close to the shores for millennia,
providing a constant source of protein and vitamins. Lactobacillus and other bacteria have been
used as starter cultures in the traditional preparations of cheese and various dairy products.
Microorganisms have always been central in basic food processing techniques, for instance
converting fibres into edible food when fermenting dough to produce bread, or milk into cheese,
allowing its long-term preservation. They have been often used as a direct food source, as is the
case for yeast or algae.
In recent times, when the conventional production of food crops is leaving a substantial
environmental footprint, it should be made evident that microbial proteins and biomass are the
future to a sustainable food supply. This will be more cost-efficient, less wastage, and most
importantly the aftermath will lead to a low carbon footprint.
Microbial protein (MP) is an alternative source of high-quality single-cell protein (SCP) able to
replace animal protein in livestock nutrition and aquaculture. Going one step higher in the food
chain, MP is meeting the FAO/WHO requirements in terms of essential amino acid scoring
patterns for human nutrition, and therefore, humans could benefit greatly from the use of MP
directly as food. Mycoproteins are another example of MP derived from fungal species, they aid
with lots of health benefits and can use methane and CO2 as feedstock. A single cell protein that
has a high nutritional value, Spirulina has been used as a protein-rich dietary source for animal
feed as well as humans, keeping in mind the various health benefits of the cyanobacterium species.
Furthermore, the ingestion of live microbes that mediate health benefits through interactions with
the host gut as well as the resident gut microbiota, is also practiced. These, termed Probiotics, are
considered to be generally safe for most people as they allow for colonization of the gut with
beneficial microorganisms.
In conclusion, we live in a world where these tiny organisms are ubiquitous, existing even in our
own bodies and resulting in maintaining a functioning, symbiotic ecosystem like the gut
microbiome. Hence, microbial protein qualifies as an excellent source of nutritive proteins, but
other cellular components can also be of increasing importance, driving new developments for
microbial-based by-products. In the context of the need to generate new biotechnological processes
and products, this line of research and development should be explored with great care.
PROSPECTS OF MICROALGAE IN CONTEMPORARY WORLD Suryaudaysinh Rana, Kunal Chavan and Devang Barot
Department of Microbiology and Biotechnology Centre
The M.S. University of Baroda, Vadodara 390002
Microalgae are simple unicellular organisms, which usually grow in freshwater and marine water
systems. Microalgae is in the trend nowadays due to their utilities in various fields. Researches
have shown that this organism can produce certain medically important substances such as
Docosahexaenoic acid, omega-3 and omega-6 fatty acids, and beta-1, 3 glucans, which can help
to solve certain health issues such as malnutrition, diabetes, liver disorders, proteinuria,
atherosclerosis, etc. These organisms have also shown effective results in the remediation of
polluted water and the generation of biofuels. Species such as Chlorella, Chlamydomonas,
65
Scenedesmus, etc. have shown the production of biofuels. So, microalgae that were used for
bioremediation of polluted water can also be used for extraction of oils and diesel. An important
observation is that the production and cultivation of microalgae do not cause any harm to the
environment and hence, these are completely eco-friendly. In addition to that, microalgae use CO2
present in the environment and produce O2 in return. Approximately 40% of global photosynthesis
is due to these microorganisms. So, biofuel production using microalgae can be beneficial to the
environment as well as living organisms. Also, these microalgae can be a promising alternative to
antibiotics, as certain types of microalgae have shown the production of antimicrobial substances
that can inhibit the growth of some human pathogens such as Staphylococcus aureus, Micrococcus
luteus, B. subtilis, etc. Thus, these microorganisms can be considered as a better comrade to the
environment to satisfy the needs of mankind.
BIOLUMINESCENCE: A VISION FROM STREET LIGHTS TO TREE LIGHTS Shivam Pandey and Shalini Mondal
Department of Microbiology and Biotechnology Centre The M. S. University of Baroda, Vadodara 390002
Bioluminescence is light emitted by living things through chemical reactions in their bodies.
Today, scientists and engineers are trying to harness the radiance of living things. Roads, in the
future could be lit by glowing trees instead of streetlamps, thanks to the breakthrough creation of
bioluminescent plants. Imagine: No more street lamps with broken bulbs or dimly-lit alleys. Instead, your evening stroll
is illuminated by luminous trees giving off a calming blue hue.
But why? Street lights are incredibly expensive. Also, lighting a city contributes to a lot of
emissions. Bioluminescent trees would be greener alternatives.
The goal is to isolate the genes that cause some creatures to glow, and use those genes to
genetically engineer trees to do the same thing. The real advantage of using plants is that they only
need carbon dioxide, sunlight and water. The light is ultimately powered by the energy metabolism
of the plant itself. The light-emitting protein, called luciferin, reacts with oxygen in the presence
of an enzyme called luciferase, along with other reagents. In contrast to fire and electrically
generated light, bioluminescence is "cold light"—the reactions that create this light waste very
little energy as heat.
Experts injected specialized nanoparticles into the leaves of a watercress plant, which caused it to
give off a dim light for nearly four hours. The nanoparticles helped reach the enzyme and its
substrate to the right part of the plant and also prevented them from building to concentrations that
could be toxic to the plants. Researchers believe with further tweaking, the technology could be
used to provide lights bright enough to illuminate an entire street, as well as a switch mechanism
to turn on and off the tree light.
So, are you ready for a mini-tour: FROM STREETLIGHTS TO TREELIGHTS?

Artificial intelligence (AI) has been termed the machine for the fourth industrial revolution. One
of the main challenges in drug discovery and development is the time and costs required to sustain
the drug development pipeline. It is estimated to cost over 2.6 billion USD and take over a decade
to develop therapeutics like cancer. This is primarily due to the high numbers of candidate drugs
failing at late drug development stages. Many sizable pharmaceutical and biotech companies have
made considerable investments in AI. This is primarily due to recent advancements in AI, which
have displayed the possibility of rapid low-cost drug discovery and development.
MICROPLASTICS IN HUMAN PLACENTA

Microplastics are particles smaller than five millimetres deriving from the degradation of plastic
objects present in the environment. Microplastics can move from the environment to living
organisms, including mammals. There are several reports of MPs in food, and in seafood, sea salt,
and in drinking water. Microplastics have also been detected in the gastrointestinal tract of marine
animals, and also human intestine. Inside tissues, MPs are considered as foreign bodies by the host
organism and, as such, trigger local immunoreactions. Furthermore, MPs can act as carriers for
other chemicals, such as environmental pollutants and plastic additives, which may be released
and are known for their harmful effects.
"For the first time microplastics were detected by Raman micro-spectroscopy in human
placentas."
Raman Micro-spectroscopy is a well-assessed vibrational technique, widely and successfully
applied in the biomedical field, to characterize both biological samples.
The potential presence of man-made MPs in placenta may harm the delicate response of
differentiation between self and non-self with a series of related consequences on embryo
development that need to be defined.

The major challenge for the future is increasing the CO2 concentration in atmosphere, leads to
many undesirable changes. As plants can fix the CO2 with the help of a catalytic enzyme -
RubisCo. But the rate of fixation of CO2 is very low.
The motivation behind this research is to find a new way to fix CO2 at a speedy rate and there
are always chances to improve the existing biology with synthetic biology.
ECR: an enzyme which fixes carbon dioxide at very efficient rate. ECR enzymes are much
more efficient than RubisCO, are taken from different organisms.
By taking 17 such enzymes from 9 different organisms and to bring them together and
harmonize them to work as a team to get CETCH cycle. These synthetically combined enzymes
later put into the plant cells.
So that it can enhance the CO2 fixation mechanism.

Recent advancements in gene editing technology with use of programmable nucleases (ZFNs,
TALENs, CRISPR – Cas 9) has opened up new possibilities in targeting specific genes / DNA
sequences. This has increased the accuracy of gene manipulation for research and clinical purpose
in eukaryotes.
Traditional cancer therapy methods caused damage to normal somatic cells along with tumor cell.
Using these gene editing tools, mutant cancer-causing genes can be selectively targeted and
knocked out or replaced with wild-type normal gene. Much research is now being done on
engineering stem cells and developing anti-tumor T cells.

One of the most severe public health issues in the world is the Human Immunodeficiency Virus
(HIV), the virus that causes Acquired Immunodeficiency Syndrome. HIV-AIDS remains one of
the most difficult conditions to treat in the 21st century. However, multiple antiretroviral
medications are present in the present situation, rendering the disease chronic rather than worse,
68
which helps to improve the survival rate. Antiretroviral drugs are manageable, but bioavailability,
poorer permeability; bad medication half-life restricts potent operation. High dose drug
administration leads to greater toxicity, which induces side reactions and develops resistance to
the strain of HIV. There is a lack of potent drug targeting owing to its volatility, chemical
degradation, and restriction of the tissue barrier. The use of nanotechnology to produce anti-
retroviral medications has the potential to treat AIDS. Nanocarrier's effective nanotechnology
delivery system (liposomes, dendrimers, nanoparticles, polymeric micelles, nano-emulsion,
nanovesicles) plays a vital role in the delivery of drugs. Nanocarrier has revolutionized the area of
pharmaceuticals in the world of drug distribution in a living system. This analysis reveals the nano-
based potent systems that are incorporated or enclosed with ARV drugs to improve their efficacy
or effectiveness with a low adverse effect on HIV abortion.

It’s hard to predict which drug would work best on your body. OOC is a multichannel 3D
microfluidic cell culture cell, engineered in layer and channel, that stimulates the activities,
mechanisms, physiological responses of entire organ. Virtual human on a chip can be created by
interconnecting various chips for better response. Till now several chips have been developed
including heart, kidney, liver, gut, lungs, mammary gland, lymph node, brain and eye.

APPLICATION OF FERMENTATIVE YEAST IN WINE PRODUCTION Gaurav Madhukar Patekar
Department of Microbiology and Biotechnology centre,
The M.S. University of Baroda, Vadodara 390002
In alcoholic fermentation, glucose is converted to ethanol by the yeast, a unicellular fungus. The
mechanism involves the conversion of glucose to pyruvate by EMP pathway and then
decarboxylation to form aldehyde which in turn is converted to ethanol by NADH reduction. The
best-known organism to perform this reaction is Saccharomyces cerevisiae commonly known as
Baker’s yeast. Demonstration of alcohol fermentation can be carried out by adding simple sugar
i.e., glucose to warm water followed by addition of Baker’s yeast in a bottle. In order to check for
the CO2 production as a by-product, we can tie a balloon at the neck of the bottle. In other two
bottles, controls will be kept in which no yeast and no sugar is added. The presence of CO2 in
balloon will indicate alcoholic fermentation by yeast, while its absence will infer no fermentation.
The same process is utilized in the industry for the production of beer, wine and also in baking.
Naturally, yeast is found on ripe fruits, which can cause the spontaneous fermentation to produce
Grape-wine. Thus, yeast is of great economic importance.
The wine production can be demonstrated by using the principle of fermentation in a glass jar. The
grapes will be cleaned and crushed and transferred into the jar. The activated yeast and sugar
70
solution will be added in it. The contents of the wine jar will be mixed thoroughly twice a day and
kept at 25°C. Later, mixing is discontinued for anaerobic conditions which will favour alcoholic
fermentation. After 3-5 days, wine is filtered and allowed for secondary fermentation for 7-11 days
at 25°C. The broth can be smelled to check for presence of alcohol. The wine can be aged to
develop new flavours and aroma.
BACTERIAL PROTEIN MEDIATED HEAVY METAL WATER CONTAMINATION
DETECTION Shrutika Padwal & Harshita Sharma
Department of Microbiology and Biotechnology Centre,
The M.S. University of Baroda, Vadodara 390002.
Heavy metals are toxic metals having density five times greater than water. The main threats to
human health from heavy metals are associated with exposure to lead, cadmium, mercury and
arsenic. These metals have been extensively studied and their effects on human health are regularly
reviewed by international bodies such as the WHO. Long-term exposure to arsenic in drinking-
water is mainly related to increased risks of cancers, neurological and cardiovascular defects, as
well as skin lesions such as hyperkeratosis and pigmentation changes. Health threshold limit in
drinking water, specified by the WHO, is 10 µg/L (equivalent to 10 ppb or 0.13 µM). Precise
determination of such a low concentration in a stationary laboratory environment is performed
using sophisticated instrumentation like inductively coupled plasma mass spectrometry, atomic
absorption spectroscopy or liquid chromatography tandem mass spectrometry, which are
inherently not suitable for field testing on the other hand commercially available colorimetric tests
are usually based on the highly sensitive and specific Gutzeit reaction, but their major disadvantage
is that they require hazardous HgBr2 to be used. In the last two decades both cell-free (DNA- or
protein-based) and cell-based sensing layers have been developed. Some of the whole-cell based
sensors reach the maximum allowable concentration (MAC) limit and are highly selective.
Moreover, field-application of these sensors cannot meet practical requirements in general, due to
their nature of being living organisms.
As environmentally friendly alternatives, electrochemical detection methods can be combined with
various sensing layers in affordable portable devices. Direct electrical output of these devices is
convenient to handle and analyse. Moreover, the detection of low concentration toxicants by
electrochemical methods can be combined with various signal amplifier methods or microsystem
technology on electrochemical nano-biochips enabling the construction of hand-held equipment
for field monitoring. Flagellin is the principal component of bacterial flagellum, and is present in
large amounts on nearly all flagellated bacteria. A sensing system can be designed with genetically
engineered flagellin proteins and used along with electrochemical detection systems for field
monitoring.

The M. S. University of Baroda, Vadodara – 390002
Cultivation of microorganisms from different habitats such as water bodies, soil surfaces and air
can be carried out using simple experiments. Microbes such as bacteria, fungi, viruses are present
everywhere and found on every surface and hence they are ubiquitous. For example, fungi as
fungal spores and viruses as viral particles, which can travel as bioaerosol. These bioaerosols are
basically atmospheric particles, mist of dust of µm range, associated with metabolically active or
inactive viable particles that may vary considerably in size and composition depending on a variety
of factors including the type of microorganism or toxin, the type of particles to which they are
associated. Common sources of aerosols include soil, water and sewage. Although microorganisms
are responsible for most of the infections, not all microorganisms present in the air cause infection.
Microorganisms present in the atmosphere mix with water during rainfall and are mixed with soil
and water bodies. To check their presence, we can perform simple experiments using things that
are easily available at home such as potato sugar and gelatine. Growth of the invisible microbes
can be visualised using homemade crude potato medium. For this, potatoes are boiled till they get
moist and then potato water is filtered, mixed with sugar solution followed by addition of
agar/Gelatine powder, and poured into plates. Then, a sample is added, and observed for the growth
of microbes upon sufficient incubation.
The Growth of different microbes with varying morphology on the crude potato medium may
clearly give an indication about their existence in our nearby surroundings to which we are exposed
on a daily basis.

TOTAL INTERNAL REFLECTION ON A ROUGH SURFACE OF A ROCK WITH THE
HELP OF CARBON SOOT Divya Barmeda
Department of Physics
The M. S. University of Baroda, Vadodara 390002.
Usually, reflection is not seen over a rough surface under any circumstances. But, by accumulating
fine powdery substances which are hydrophobic in nature, like carbon soot produced due to
incomplete combustion, over that rough surface, phenomenon like total internal reflection can be
reproduced by dipping that surface in some watery solution. This, happens due to formation of
very thin layer of air over the surface due to hydrophobic nature of carbon soot that is accumulated
over that surface. Here, fine powder of carbon soot, when seen microscopically, can be considered
as a landscape having dips at few places and peaks other places, now the water forms a uniform
layer (due to the essence of surface tension) across the peaks leaving some space in between where
dips are located. In this space air is present, as a result of which the surface separating air and water
acts as a center for total internal reflection. Total internal reflection occurs when light travels from
a denser medium to rarer medium if and only if the angle of incident light is greater than
arcsine(r/d), where “r” is refractive index of rarer medium and “d” is refractive index of denser
medium. If the angle of incident light is less than this then the light penetrates into the rarer medium
and would get absorbed by the soot and the surface would be seen black when seen from outside.
Also, here the uniform surfaces of water that formed are from peak to peaks of carbon soot
landscape whose heights vary at different places, as a result of which the overall surface as seen
on zooming out at microscopic level will have a texture similar to that of a crumpled paper.
Considering this, if no object is present in the vicinity of this surface (in the watery medium side),
the overall surface will be seeming to be silver-ish (i.e., due to non-uniformed shining) in color.
But if some object is in vicinity of that surface a slight hue of that object’s color can be seen over
that surface.

A STUDY OF PARTICLE ACCELERATORS Aritri Mohanta & Ashish Solanki
Department of Physics
The M.S. University of Baroda, Vadodara 390002
Our project is about Particle accelerators. As the name suggests, a particle accelerator is a machine
that can accelerate charged particles to very high speeds and energies. It uses electromagnetic
fields to propel charged particles or ions to very high speeds and contains them into sharp beams.
The basic principle is that the energy and speed of a charged particle can be increased by passing
it through a potential difference again and again. The need for an article accelerator was felt in
order to be able to study the properties of atomic nuclei and subatomic particles. There are many
different types of particle accelerators that have evolved over time, such as Linear Accelerator,
Cyclotron, Synchrocyclotron, Synchrotron and Betatron.
It all started when Cockroft and E. Walton, E. Rutherford's collaborators, started studying methods
to accelerate a particle beam to energies of hundreds of KV. They finally produced, in 1932, what
is believed to be the first true particle accelerator, delivering a 400 KV collimated beam. Ernest O.
Lawrence was awarded the Nobel Prize in 1939 for the invention of the Cyclotron using which he
later managed to accelerate a proton to 1.1 MeV with an 11-inch cyclotron.
However, there were certain limitations to a cyclotron such as its inability to accelerate a positive
ion beyond a certain limit, and its incapacity to accelerate electrons. Hence the Synchrocyclotron
and the Betatron were developed to overcome these limitations respectively.
Particle accelerators have applications in both theoretical physics as well in medical sciences. Ion
beams from cyclotrons are used in proton therapy, to penetrate the body and kill tumours by
radiation damage. Furthermore, Synchrotron light sources are used in DNA research to define how
the ribosome translates DNA information into life. In addition, LHC (Large Hadron Collider) was
responsible for discovering Higgs Boson.
LHC can achieve an energy that no other particle accelerator can reach. The aim of the LHC's
detectors is to allow physicists to test the predictions of different theories of particle physics,
including measuring the properties of the Higgs boson and searching for the large family of new
particles as well as other unsolved questions of physics.
Physicists hope that LHC helps answer some fundamental physics questions such as the nature of
the Dark Matter, existence of extra dimensions, asymmetry between matter and antimatter, etc.

Tyndall effect
Abhishek,
Department of Physics, Facuty of Science
The Tyndall effect is light scattering by particles in a colloid orin a very fine
suspension. Also known as Tyndall scattering, it is similar to Rayleigh scattering, in
that the intensity of the scattered light is inversely proportional to the fourth power
of the wavelength, so blue light is scattered much more strongly than red light. An
example in everyday life is the blue colour sometimes seen in the smoke emitted by
motorcycles, in particular two-stroke machines where the burnt engine oil provides
these particles. Under the Tyndall effect, the longer wavelengths are more transmitted
while the shorter wavelengths are more diffusely reflected via scattering. The Tyndall
effect is seen when light-scattering particulate matter is dispersed in an otherwise
light- transmitting medium, when the diameter of an individual particle is the range
of roughly between 40 and 900 nm, i.e. somewhat below or near the wavelengths of
visible light (400–750 nm). It is particularly applicable to colloidal mixtures and fine
suspensions; for example, the Tyndall effect is used in nephelometers to determine
the size and d density particles in aerosols and other colloidal matter (see
ultramicroscope and turbidimeter).It is named after the 19th-century physicist John
Tyndall. Rayleigh scattering is defined by a mathematical formula that requires the
light-scattering particles to be far smaller than the wavelength of the light. For a
dispersion of particles to qualify for the Rayleigh formula, the particle sizes need to
be below roughly 40 nanometres (for visible light), and the particles may be
individual molecules. Colloidal particles are bigger, and are in the rough vicinity of
the size of a wavelength of light. Tyndall scattering, i.e. colloidal particle scattering,
is much more intense than Rayleigh scattering due to the bigger particle sizes
involved. The importance of the particle size factor for intensity can be seen in the
75
large exponent it has in the mathematical statement of the intensity of Rayleigh
scattering. If the colloid particles are spheroid, Tyndall scattering can be
mathematically analyzed in terms of Mie theory, which admits particle sizes in the
rough vicinity of the wavelength of light. Light scattering by particles of complex
shape are described by the T-matrix method. A blue iris in an eye is due to Tyndall
scattering in a translucent layer in the iris. Brown and black irises have the same layer except
with more melanin in it. The melanin absorbs light. In the absence of melanin, the layer is
translucent (i.e. the light passing through is randomly and diffusely scattered) and a noticeable
portion of the light that enters this translucent layer re-emerges via a scattered path. That is,
there is backscatter, the redirection of the light waves back out to the open air. Scattering
takes place to a greater extent at the shorter wavelengths. The longer wavelengths tend to pass
straight through the translucent layer with unaltered paths, and then encounter the next layer
further back in the iris, which is a light absorber. Thus, the longer wavelengths are not
reflected (by scattering) back to the open air as much as the shorter wavelengths are. Because
the shorter wavelengths are the blue wavelengths, this gives rise to a blue hue in the light that
comes out of the eye. The blue iris is an example of a structural color, in contrast to a pigment
color. When the days sky is overcast, sunlight passes through the turbid layer of the clouds,
resulting in scattered, diffuse light on the ground. This exhibits Mie scattering instead of
Tyndall scattering because the cloud droplets are larger than the wavelength of the light and
scatters all colors approximately equally. When the daytime sky is cloudless, the sky's color
is blue due to Rayleigh scattering instead of Tyndall scattering because the scattering particles
are the air molecules, which are much smaller than the wavelengths of visible light. On
occasion, the term.Tyndall effect is incorrectly applied to light scattering by large
(macroscopic) dust particles in the air.
Plasma Globe
Aritri Mohanta, Somya Shree Sahu, Bhargavsoni
Department of Physics, Faculty of Science, The Maharaja Sayajirao University of Baroda
76
A plasma is created whenever atoms of a gas are heated up so they are extremely hot. The
atoms have so much energy that when they collide, the electrons get knocked off. Therefore, a
plasma is a bunch of electrons and ions.
The plasma globe is a miniature Tesla coil. Inside the ball is a coil of wires that have
electrons going through them oscillating at a very high frequency. This shakes the atoms around
the wires so hard that their electrons start to fall off! Inside the glass globe is a partial vacuum.
This just means that some of the air has been sucked out. Because there is not as much air in there,
it is easier to make electric sparks that can be seen.
The electrons then travel out into the air from the glass ball. We know this because the
plasma ball lights up the light bulb. If you touch the plasma ball, all of the electrons will go through
you to the ground. You see only one big spark inside the ball where you put your hand. If you
stand on a stool, you are insulated from the ground and get filled with electrons. This means you
can light up a fluorescent light bulb
THE DIFFUISION CLOUD CHAMBER
Aritri Mohanta, Somya Shree Sahu, Bhargav Soni
Department of Physics, Faculty of Science, The Maharaja Sayajirao University of Baroda
A cloud chamber is a device that makes visible the paths of particles emitted as a result of
radioactive decay. When subatomic particles enter the cloud chamber they bump into air or alcohol
molecules producing free ions. The ions serve as a starting point for the growth of visible droplets
in the space that contains more condensed vapour than usual. The droplets form the visible trails.
The cloud chamber provides a supersaturated atmosphere in which this is possible.
In the diffusion cloud chamber a large difference in temperature is maintained between the
top and the bottom of the chamber, usually by cooling the bottom with dry ice. The gas in the
77
chamber, in this case air, is saturated with a vapour, usually alcohol. The air-vapour mixture cools
as it diffuses to the frigid bottom, creating a supersaturated environment, the cloud.
MATERIALS Required: IPA(isopropyl alcohol), sponge, glass aquarium, metal plate with black
base, a radioactive source(here Thorium) and dry ice.
Magnetic levitation
Somya Sahu, Aritri Mohanta and Bhargav Soni
Department of Physics, faculty of Science, The Maharaja Sayajirao University of Baroda
78
The principle of magnetic levitation is that a vehicle can be suspended and propelled on a
guidance track made with magnets. The vehicle on top of the track may be propelled with the help
of a linear induction motor. Although the vehicle does not use steel wheels on a steel rail they are
still referred to as trains as by definition they are a long chain of vehicles which travel in the same
direction. This is the definition of a MAGLEV train.As the frictional parts are minimum in this
type of technology, the MAGLEV trains are known to have more speed, smoothness and less
sound.
The train will be floating
about 10mm above the
magnetic guiding track.
The train will be propelled to
move by the guide way
itself. Thus, there is no need
of any engine inside he train.
The detailed working of
MAGLEV train is shown
in the figure below. The
train is propelled by
the changing in magnetic
fields. As soon as the train starts to move, the magnetic field changes sections by switching method
and thus the train is again pulled forward. The whole guide way is run by electromagnets so as to
provide the magnetic effect.Thus the power needed for the whole process is less when compared
to a conventional electric train. Amongst the power used, only a little is used for the levitation
process. But a higher percentage of power is needed to overcome air friction.
Spintronics: A future vision of electronics
Kishan H. Mali*, Rushikesh Pokar
Department of Physics, Faculty of Science
Electronic devices utilize the charge of electrons to store information. Maintaining the data
stored in 0 or 1 logic in these devices for a long time, high heat dissipation, low switching speed
were major problems in the electronic devices. These problems are overcome in devices based on
spintronics, in which the spin property of electrons instead of charge is exploited to store
79
information. Since the discovery of TMR in 1975 and GMR in 1988 various spin-based effects
have been observed and utilized in memory storage and switching devices such as MRAM,
magnetic hard-drives, spin-based transistors, magnetic field sensors, and spin filters. The field of
spintronics has evolved exponentially in the last decade providing the ability to design smaller,
faster, and much more efficient memory storage devices compared to conventional electronic
devices.
DARK MATTER & DARK ENERGY
Nitya Parikh, Annapurnasingh,
Department of Physics, Faculty of Science
From the tiny atom to everything visible to human eye, is classified as ordinary matter. We can
see these things because of the light reflected by the objects is captured by the light receptors
present in the human eyes. Surprisingly our universe is made of only 5% ordinary matter &
remaining 95% comprises of 25% dark matter & 70% dark energy, which are invisible. This
implies whatever we, the humans, experience is just a very small portion of the reality. So how did
this dark matter & dark energy being discovered? Swiss born astronomer, Fritz Zwicky, studied
the images of roughly 1000 galaxies that make up the COMA CLUSTER. To his astonishment, he
found that the galaxies move so fast, that they should have simply flown apart; which isn’t the
case. This is where he speculated that something acts as a belt & named this “belt” as dark matter.
Initially this wasn’t accepted by the astronomers, since agreeing to him meant to oppose the laws
of Newton. So they rejected his ideas by saying that there had been some kind of mistake in his
research. However after 27 years, in 1960, a female astronomer named Vera Rubin, found the
similar results while studying our neighbouring Andromeda galaxy. This led to the acceptance of
the dark matter theory. Dark matter interacts with gravity on the other hand dark energy opposes
the gravity. Dark energy is the mysterious force causing the universe’s expansion to accelerate,
with the passage of time. It’s the unknown form of energy affecting the universe on the largest
scales. Their discovery refuted the earlier studies regarding the universe that was based on the
newton’s laws; which stated that “Universe’s expansion would decelerate resulting in the
retraction leading to its collapse. However“THE RED SHIFT” concept by Edward Hubble, proved
the expanding of universe.This discovery led to the further conclusion that dark matter is an

A microphone is a device which converts acoustical energy(sound waves) into electrical energy.
Several types of microphone are used today, which employ different methods to convert the air
80
pressure variations of a sound wave to an electrical signal. The most common are the dynamic
microphone, which uses a coil of wire suspended in a magnetic field.
Apparatus: Cardboard box(small), Graphite (or Pencil leads), Crocodile Wires, 9v Battery, A
sharp Knife and Speaker wires (or Earphone).
Circuit
Principle:
It works on the principle of Simple Harmonic Motion. The varying pressure in air vibrates the
graphite lead up and down, causing change in resistance. Due to this change in resistance,
potential drop on the speaker changes. Hence pressure variations are converted into electrical
signals.
Applications:
Microphones are used in many applications such as telephones, hearing aid, public address
systems, for concert halls and public events, motion picture production, live and recorded audio
engineering, sound recording, two-way radios, megaphones, radio and television broadcasting.
They are also used in computers for recording voice and speech recognition.

Perseverance, nicknamed Percy is a carsized Mars rover designed to explore the Jezero
Crater on Mars as part of NASA's Mars 2020 mission. It was manufactured by the Jet Propulsion
Laboratory and launched on 30 July 2020 at 11:50:00 Confirmation that the rover successfully
landed on Mars was received on 18 February 2021 at 20:55. As of 26 February
2021, Perseverance has been on Mars for 7 sols (8 Earth days). Perseverance has a similar design
to its predecessor rover, Curiosity, from which it was moderately upgraded; it carries seven
primary payload instruments, 19 cameras, and two microphones. The rover is also carrying the
mini-helicopter Ingenuity, an experimental aircraft that will attempt the first powered flight on
another planet.The rover's goals include identifying ancient Martian environments capable of
supporting life, seeking out evidence if microbial life existed in those environments, collecting
rock and soil samples to store on the Martian surface, and testing oxygen production from the
Martian atmosphere to prepare for future crewed missions [1].
Swati Mohanis an Indian origin and play important role in this NASA mars mission. Swati Mohan
led the attitude control of mars mission during operations and was the lead systems engineer
throughout development. The attitude control system points the vehicle where it needs to be and
help figure out where the spacecraft is oriented in space [2]. She completed her B.S from Cornell
University in Mechanical & Aerospace Engineering, and her M.S. and Ph.D. from MIT in
Aeronautics/Astronautics. She has worked on multiple missions such as Cassini (mission to
Saturn) and GRAIL (a pair of formation flown spacecraft to the Moon). She has worked on Mars
2020 since almost the beginning of the project in 2013. She is currently the Mars 2020 Guidance,
Navigation, and Controls Operations Lead, at NASA's Jet Propulsion Laboratory in Pasadena, CA.

This project is based on data science. In this project we have presented a demonstration showing
what is statistics, what statistician do with the data and how statistics works to draw conclusions.
There are 6 stages involved in data processing.
First stage is framing of the problem. In this project we want to know how the novel pandemic
affected the life of people.
Second stage is collection of data. In this we have first prepared the questionary to collect
necessary data which can be used to analyse and draw some conclusion. We have used google
based form. The questionary involves gender, age group, relationship status, to which working
occupation the belongs to, did people got proper facilities to work or study from home from home
or not , their satisfaction from online services , how they spend their lockdown time, their working
status, their situation during lockdown, their physical health, did they avail their daily needs like
grocery, medicines, sanitizer, etc., did they received help from government or non-government
programs or not, how much time they spend at home and their overall experience. We have
collected 90 responses.
Third stage is organization of data. In this we have cleaned the raw data and have transformed it
into tabular form.
Fourth stage is presentation of data. In this we have explored the data and have examined it
carefully to draw hidden relationships. For this we have used pie chart, bar diagram, horizontal bar
diagram.
Fifth stage is analysis using statistical methods. We have used inferential methods. We have used
statistical tools like fitting of distribution and testing of hypothesis.
Sixth stage is interpretation and conclusion. Here, after performing all the above stages we
conclude that there is association between age group and situation during COVID-19 pandemic.
83
So, situation of people depends on their age group. Also, we have shown that the person we select
from the population would have neutral or better experience during pandemic.

The demand to predict stock prices are Extremely high, hence it is the need for stock market
analysis. It is Analysis and Prediction of project on technical analysis, visualization and prediction
using data provided by Google Finance. The purpose of this project is to comparatively analyse
the effectiveness of prediction algorithms on stock market data through visualization to predict
future stock behaviour and value at risk for each stock. Thus, we can say that stock market is such
a wide field that we can have good trade in it and many people invest and find good opportunity
for doing business. As every coin has two side even stock market has two side.
Sometimes investor may have good income and sometimes due to low SENSEX it may happen
that they might have to take loan and debt themselves. We have to make opportunity by ourself
and they need to think about future. Hence, we can conclude that it is such a wide imaginary world
where people get lost and sometimes due to over pressure they might get in depression and if they
have good profit in stocks due to greediness also, they might forget their family members and
others so deeply that they feel loneliness. Statistics is such a huge field which involves almost all
the surroundings and we use it regularly for our prediction and analysis.

How happy Barodians are: A Happiness survey on Vadodara Citizens
Kinjal Kanwar and Komal Patil
Department of Statistics
In today’s fast moving and highly stressful life, we all are running after materialistic things and
are trying to find happiness in it. But do we actually know what happiness is and if we know how
to define it then, can we measure it in any way. To find the answers to such questions there have
been numerous studies around the world. A breakthrough in quantifying happiness or wellbeing
was made by Bhutan by calculating their country’s Gross National Happiness (GNH) instead of
Gross National Product (GNP). The term GNH was coined by the 4th King of Bhutan Jigme Singye
Wangchuk. Since then there have been different studies and researches conducted by various
organizations like United Nations Sustainable Development Solutions Network which publishes
World Happiness Report every year since 2012.
According to which, India is ranked on 144th position out of 156 countries in 2020. So, it becomes
quite alarming to study about various factors responsible for happiness. Hence, we have conducted
a study: “How happy barodians are: A happiness survey on Vadodara Citizens”. This study was
conducted before covid-19 breakdown. Happiness is an abstract concept which can not be
measured but psychologists and researchers have long tried various ways to quantify it and have
given different definitions for happiness ,all of which could be summarized as : Happiness is being
satisfied with life, being in a good mood, feeling positive emotions, feeling enjoyment, etc.
Researchers have identified various contributors of happiness like physical health, income, social
relationships etc. In study of Gross National Happiness by Bhutan government, they have
identified 9 domains and 33 indicators of happiness like education, health, psychological wellbeing
etc.
Similarly, in our study we have measured happiness based on 7 domains -health, marriage, family,
education, social relationships, occupation, general life satisfaction. We have further identified 28
indicators based on these domains and have asked a question regarding all of them, in which
respondents have answered based on a 5-point scale from highly agree to highly disagree. For our
study, we have taken a random sample of 315 people from 4 wards of Vadodara, and asked them
to fill the questionnaire.
Based on their responses we have calculated an average happiness score of each individual by
using weighted average method. In calculation of GNH, Bhutanese have given equal weights to
all the 9 domains. Since all the indicators are not equally important for an individual’s happiness
but each of them are important to some person at a given point of time. So, using some statistical
techniques we have given weights to different domains and then using these weights we have
calculated the average happiness scores and according to them we have divided the people into 3
categories; unhappy, happy and extremely happy.
From our study we have found that 86% female respondents are happy and 83% of the male
respondents are happy. Among married and unmarried people, we have seen that 85% of the
married are happy while 84% of the unmarried are happy. Since family is an important factor for
85
happiness so we have also asked the people about the family type they are currently living in; and
we found that 87 % of the people living in nuclear families are happy while 82% of the people
living in joint families are happy.
We have also calculated an overall happiness index for Vadodara city. For finding this index we
have used two thresholds: sufficiency threshold, happiness threshold. If a person’s weighted
average score is 7 or above in particular domain then he / she is considered sufficient in that
domain. And if the person enjoys sufficiency in 4 out of 6 domains then he / she is considered
happy. To calculate GNH we need no. of happy and not yet happy people so in our study we had
(255 out of 315) i.e. 80.95% people in the sample were happy and (60 out of 315) i.e. 19.04%
people in sample were not - yet - happy. So overall happiness index of Vadodara city came
to be 8.83 out of 10. So, we can see that barodians are quite happy.
BAYESIAN BRAIN
Amisha Yadhav and Srishti sen
Department of Statistics
Suppose you are going to a market and you see a dog-like creature running towards you, your
belief that it will attack you may be 34%; if you recognize that it’s a Doberman, your belief that
you’ll be attacked may rise to 78%; if it starts barking, 92%; if another barking dog passes you
from behind, the probability of your attack-belief being true drops again. From this example we
can see that how your certainty of a belief may change as you gain new evidence.
Initial belief + new evidence = updated belief.
To explain such type of phenomena scientist gave an idea called Bayesian brain that uses a
mathematical model to describe how the brain works. It explains how the brain is influenced by
the past experience, their moods and all sorts of other factors. Since everyone has lived a
different life , everyone’s brain is different.
Bayes’ law is the mathematical formalization of that idea: P(B|E)=P(E|B)*P(B)/P(E), which
calculates the conditional probability of your belief B being true, given evidence E. This is what
the brain approximates4 during predictive processing. In particular, your brain updates its
statistical model of the world by integrating prediction errors in accordance with Bayes’
theorem; hence the name Bayesian brain.
The crucial point in understanding the Bayesian brain is that: the internal model of the world
within the brain suggests that processes in the brain model processes in the physical world. In
order to successfully predict the future, the brain needs to run simulations of the world on its own
hardware. These processes need to follow a causality similar to that of the external world, and a
world of its own comes alive in the brain observing it.

Background: WHO declared COVID-19 as a pandemic on 11 March 2020 due to its large-scale
spread across the world. The spread of the pandemic COVID-19 has posed a great public health
challenge globally. In India, Gujarat is one of the leading states in terms of number of deaths
wherein all the districts have been already affected by the spread of the disease. Ahmedabad, Surat,
Vadodara, Rajkot, districts contribute the large number cases from Gujarat. There is a need for a
focused plan to reduce the deaths and spread of the disease.
Objectives: The study attempt to examine the progress of COVID 19 cases till 22nd Feb 2021 long
with the trend of case fatality and positivity rate in Gujarat.
Data source and Methodology: The data available on COVID-19 portal given by the Government
of India has been used to show the status of COVID 19 pandemic. Case Fatality Rate (CFR) and
Positivity Rate (PR) has been calculated from the given data. Correlation coefficient has been used
to show the causal relationship between PR and CFR.
Results: A total of 267104 COVID-19 infected cases and 4405 deaths were found in Gujarat (With
2.3% PR and 1.6% CFR). June month represent as a highest (9.8%) and January 2021 (1.42%) as
a low positivity rate in Gujarat. Whereas highest CFR (6.65%) taken place in the month of May
and low in the month of January 2021 (0. 49%).From the Month of August CFR and PR both
started decline in Gujarat. A positive correlation exists (+0.88) between PR and CFR. 1731 active
case is there in Gujarat as on date.
Conclusion: Although PR and CFR shows a decline trend, but COVID-19 has become a major
public health challenge all over the world as well as India and Gujarat. So government and people
should take precaution to stop the spread until the vaccination covered in whole population

Theories Regarding Experiment:
Definitions
1. Probabitity : Probability is the measure of the likelihood that an event will
occur in a Random Experiment. Probability is quantified as a number
between 0 and 1, where, loosely speaking, 0 indicates impossibility and 1
indicates certainty. The higher the probability of an event, the more likely it is
that event will occur.
2. Bias : In statistics, the bias of an estimator is the difference between this
estimator’s expected and true value of the parameter being estimated.
3. Unbiased : An estimation or decision rule with zero bias is called unbiased.
4. Estimation : Estimation statistics is a data analysis framework that uses a
confidence intervals, precision planning, and meta-analysis to plan
experiments, analyze data and interpret results. It is distinct from null
hypothesis. There are mainly two types of estimation.
1. Point Estimation : In statistics estimation involves the use of sample data
to calculate a parameter at the point. Than that estimation is known as the
point estimation.
2. Interval Estimation: In statistics estimation involves the use of sample
data to calculate a parameter at interval/Range. Than that estimation is
known as interval estimation.

For years, doctors and researchers have turned to the world around them to try and find
cures for diseases, to alleviate pain and provide all kinds of services to patients. In fact, there is a
branch of the scientific world known as entomology that studies the relationship between insects
and humans. That means that scientists in this area study the ways insects can be used as food and
in religious rituals. However, one particularly fascinating area of entomology is the study of
medical uses for insects.

“Poop”- What comes to your mind after hearing this? Waste material? Well, it turns out that it is
actually beneficial. In the following video presentation, 7 species of animals have been selected
which are associated with weird and scientifically important poop facts. Here, you will get to learn
about poop being used as coffee, as gunpowder, as perfumes, as fertilizers, as water purifiers and
poop that smells so good that it can refresh your mood. More importantly, poop, which is readily
available and yet ignored, has ecological importance to it-Like contributing to Carbon cycle,
Sulphur cycle, Nitrogen cycle and keeping greenhouse gases like Methane in check. Therefore,
this topic has been chosen to create awareness among people about poop and its implications to
the future of this planet. Also, the importance of these species in the overall well-being of their
ecosystems and how poop plays a role in it has been discussed.

Garbage arising from human or animal activities, that is abandoned as unwanted and useless is
referred as solid waste. Generally, it is generated from industrial, residential and commercial
activities in a given area, and may be handled in a variety of ways. However, waste can be
categorized based on materials such as paper, plastic, glass, metal and organic waste. Solid waste
disposal must be managed systematically to ensure environmental best practices. Solid waste
disposal and management is a critical aspect of environmental hygiene and it needs to be
incorporated into environmental planning.
Solid waste disposal management is usually referred to the process of collecting and treating solid
wastes. It provides solutions for recycling items that do not belong to garbage or trash. Solid waste
management can be described as how solid waste can be changed and used as a valuable resource.
Improper disposal of municipal solid waste can create unsanitary conditions, and these conditions
in turn lead to pollution of the environment. Diseases can be spread by rodents and insects. The
tasks of solid waste disposal management are complex technical challenges. They can also pose a
wide variety of economic, administrative and social problems that must be changed and solved.
1) To devise a system of storage of waste and segregation of recyclable waste at source & improve
system of primary collection of waste.
2) To devise more efficient system of day-to-day cleaning, conventionally and mechanically.
3) To eliminate manual handling of waste and open transportation vehicles.
4) To improve the system of transportation of waste by ensuring "handling waste only once".
5) To reduce quantity of waste going to landfill site by adopting suitable technology.
8) To ensure safe disposal of waste including bio medical waste, C&D Waste, E-Waste and another
Special category waste
.
So, I have prepared model on modern waste management techniques and new modern landfill. For
this I virtually visited Antony Lara Enviro Solutions Pvt. Ltd. There I found various new
techniques which they have implanted for waste management and disposal in Mumbai. The
processing and machineries are unique. I have explained all processing, working of machineries
and preparation/blueprint of modern landfill and its working in the video in detail.
DIGESTIVE SYSTEM IN DIFFERENT ORGANISMS
Anjali Singh & K.D.V. Sriya
Department of Zoology
The M.S University of Baroda, Vadodara 390002
Digestion is the breakdown of large insoluble food molecules into small water-soluble food
molecules so that they can be absorbed into the watery blood plasma. It is important for breaking
down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink
90
must be changed into smaller molecules of nutrients before the blood absorbs them and carries
them to cells throughout the body. Different species of animals are better able to digest certain
types of foods than others. This difference occurs because of the various types of digestive systems
found in animals. There are four basic types of digestive systems: monogastric, avian, ruminant,
and pseudo-ruminant.
In this project we are going to compare different digestive systems of different organisms by also
differentiating their average digestion time. Here we have taken major four organisms representing
each system: a pigeon, a cow, a rabbit, and human beings. Depending on their food habits and
consumption digestion time depends. Generally, bird digestion is faster compared to other
organisms. Whereas cow digestion takes time due to the regurgitation process. We also tried to
research their average digestion time. Some organs involved in digestion are different in some
species and in some they may be new organs too. Like in cows, we could observe that it is having
four chambered stomach which includes: rumen, reticulum, omasum, abomasum, likewise in
pigeon the parts include gizzard and corp.
We can write that digestive systems of all species have been shaped by environmental time
pressures over long evolutionary time spans. Nevertheless, all digestive systems must achieve the
same end points, the ingestion of biological material and its conversion to molecules that serve as
energy substrates and structural components of tissues.
Through this project, we would explain why digestion is important and how evolution made magic
and brought up wonderful organism human beings with well-developed organ systems.

As my topic itself says, I am going to present and reflect ideas about what actually adaptation is
and why it is necessary and what are the types and aspects of it. I think most of you are aware
about term adaptation but to study in detail might be boring so I have come up with interesting
idea to know and understand adaptation in various organisms in my ppt/ video.
