Why a Scientific Format?Why a Scientific Format?
• It is a means of efficiently communicating
scientific findings to the broad community
scientists in a uniform manner.
• It allows the paper to be read at several
different levels. At whatever level a
person reads your paper, they will likely get
the key results and conclusions.

Evaluating abstracts: Abstract 1-Environmental Science about the Evaluating abstracts: Abstract 1-Environmental Science about the estimation of natural rechargeestimation of natural recharge
Natural ground water recharge is estimated using the injected tracer technique in
the Bairasagara watershed of Kolar district, Karnataka (India) comprising of
medium grained granite and granatic gneiss with weathering/fracturing up to 46 m
depth. On a macroscopic scale, it is estimated that the weathered granites act as a
uniform body having a recharge capacity of about six to 200 mm per annum for an
average value of rainfall of 968 mm. Marked differences of infiltration rates (nil to
130 cm/year) were observed under cultivated and dry areas. The water level
fluctuation and recharge are found to be minimum in the ayacut area as compared
to the catchment area. Studies helped in demarcating recharge and discharge
areas. Qualitative correlation studies of estimated natural ground water recharge
have been carried out with depth to basement, resistivity of subsurface layers, and
water level fluctuations.
An attempt has been made to get empirical relationships between the recharge
versus depth to basement, and recharge versus water level fluctuations. This paper
discusses the studies carried out, the results obtained the importance of such
studies in the evaluation of groundwater resources.

Evaluating abstracts: Abstract 2- BiologyEvaluating abstracts: Abstract 2- BiologyStimulus-induced oscillations in plant cell cytosolic free calcium. Ca2+ is implicated
as a second messenger in the response of stomata to a range of stimuli. However,
the mechanism by which stimulus-induced increases in guard cell cytosolic free Ca2+
([Ca2+] are transduced into different physiological responses remains to be
explained. Oscillations in [Ca2+] may provide one way in which this can occur. We
used photometric and imaging techniques to examine this hypothesis in guard cells
of Commelina communis. External Ca2+ ([Ca2+]e), which causes an increase in [Ca2+],
was used as a closing stimulus. The total increase in [Ca2+] was directly related to
the concentration of [Ca2+]e, both of which correlated closely with the degree of
stomatal closure. Increases were oscillatory in nature, with the pattern of the
oscillations being dependent on the concentration of [Ca2+]e. At 0.1 mM, [Ca2+]e
induced symmetrical oscillations. In contrast, 1.0 mM [Ca2+]e induced asymmetric
oscillations. Oscillations were stimulus-dependent and modulated by changing
[Ca2+]e. Experiments using Ca2+ channel blockers and Mn2+-quenching studies
suggested a role for Ca2+ influx during the oscillatory behavior without excluding
the possible involvement of Ca2+ release from intracellular stores. These data
suggest a mechanism for encoding the information required to distinguish between
a number of different Ca2+-mobilizing stimuli in guard cells, using stimulus-specific
patterns of oscillations in [Ca2+].

Evaluating abstracts: Abstract (3) StatisticsEvaluating abstracts: Abstract (3) Statistics
Non-parametric ecological regression and spatial variation Ecological studies aim
to analyse the variation of disease risk in relation to exposure variables that are
measured at an area unit level. In practice it is rarely possible to use the
exposure variables themselves, either because the corresponding data are not
available or because the causes of the disease are not fully understood. It is
therefore quite common to use crude proxies of the real exposure to the disease
in question. These proxies are rarely able to explain the disease variation and
hence additional area level random effects are introduced to account for the
residual variation. In this paper we investigate the possibility to model the effect
of ecological covariates non-parametrically, with and without additional random
effects for the residual spatial variation. We illustrate the issues arising through
analyses of simulated and real data on larynx cancer mortality in Germany,
during the years of 1986 to 1990, where we use the corresponding lung cancer
rates as a proxy for smoking consumption.

Evaluating abstracts: Abstract 4-Environmental ScienceEvaluating abstracts: Abstract 4-Environmental Science
Geomorphology and pollution: the environmental impacts of lead mining,
Leadhills, Scotland The Glengonnar Water has experienced severe
environmental pollution resulting from historic lead mining operations.
Though now abandoned, the legacy of the mining era remains in the form of
river and floodplain sediments grossly polluted with metals, particularly lead
which exhibits surface concentrations in excess of 75 000 mg kg total Pb.
Geomorphological investigations link the most important mining period to a
major phase of floodplain degradation, which acted as an efficient sink for
particulate bound metals. The pattern of metal contamination within the
floodplain has been complicated by subsequent fluvial entrenchment.
However, preliminary evidence indicates that lateral and vertical variations of
metals [both total and available] can be accounted for in terms of the age of
deposit, distance downstream and local hydraulic conditions. The
effectiveness of floodplains to interrupt the delivery of sediment-bound
contaminants was highlighted by a metals budget developed for the main
channel length. This confirmed that channel bank erosion of contaminated

High frequency digital power line transmission for terrestrial and marine networks
The aim of this work was to investigate a feasibility study based on an appropriate method of propagation results, analysing suitability of communication through power line transmission channels. With this as the main aim the emphasis of the work has been placed on: initially the design of simulators resulted from the modelling of the channel, followed by low complexity protocols and modulation schemes, and the real time performance evaluation of point to point multimedia kit designed and tested for application on a QinetiQ project.
This thesis describes the work carried out in the areas of propagation, modulation design, duplex protocol, modelling and simulation and real time channel evaluation. Also presented herein is the design and implementation of conditioning units “Coupling Devices” together with implementation of remote/local control mechanism to aid the project requirement” remote control of the vessel via power line.
The effectiveness of these devices, and various measurements and real time trials of the simulators, and the multi media kit, is the prim importance throughout this thesis. Simulation results, while assessing the effectiveness of an OFDM COSSAP model, mainly are tried over an AWGN channel, and later on over a Rayliegh fading channel and subsequently over AWCN, with appropriate for power line channel, are used to illustrate and support this work. The most important results are the successful outcome of the multi media multiplexed kit trials on board RV TRITON a QinetiQ vessel, and similarly at the power line laboratory, where real time text, audio and video, as well as duplex conferencing were demonstrated with modems connecting at 33.6 kbits/s.
Finally, investigation of the three-phase 440V power line channel resulted in lodging a patent that uses the STD/STC techniques. These techniques, whilst in their field are not new, however with the diversity gain achieved when using smart power line modem design will enhance data throughputs in multiples of the presently achievable rate.

Bone mineral density and bone turnover markers in children with chronic renal failure
•Bone mineral density (BMD) at lumbar spine (L2-L4) was measured by dual energy X-ray absorptiometry (DEXA) in 21 children with predialysis chronic renal failure (CRF) and 44 children with end stage renal failure (ESRF) on regular hemodialysis. BMD results were expressed as Z-scores. Osteopenia was documented in 13 predialysis patients (61.9%) and 26 patients (59.1%) of children with ESRF. No significant correlation was observed between Z-scores and the duration of CRF or estimated creatinine clearance. In osteopenic children there was a negative correlation between Z-scores and serum phosphorus (r= -0.61, p= 0.004), intact parathyroid hormone (r=- 0.47, p= 0.03), bone specific alkaline phosphatase (r= -0.52, p= 0.02) and positive correlation with total calcium (r= 0.41, p= 0.07) and 25 hydroxy cholicalciferol (r= 0.53, p= 0.02). Osteopenic children who had iPTH values 200 pg/ml were more osteopenic than those who had lower iPTH levels (p=0.006). In conclusion osteopenia, assessed by DEXA, is frequent in children with CRF. It occurs early irrespective of the duration or the severity of CRF. In children with ESRF the degree of osteopenia is correlated to the laboratory markers of renal osteodystrophy and patients with biochemical findings of secondary hyperparathyroidism are more osteopenic than the others.
