Sap Research Grant Applications
Background
Certain trees (maple, birch, walnut, . . . )are very different from other species inthe following sense:
high sap sugar content (' 1%)capable of generating high stem pressurewhen in a leafless statecertain unusual structural characteristics
This makes harvesting their sap forhuman consumption viable
We resolved a long-standing controversyover the physical mechanism responsiblefor freeze/thaw-induced sap exudation inmaple and walnut:

– my PIMS–CSC Seminar talk on October 14

Mathematical Model – Microscale
This is a multiphysics, multiscale problem! On the cellular ormicro-scale, we solve a reference cell problem . . .
Simple (1D) radial geometry
Stefan condition governing movingsolid/liquid interface
Heat equation, but quasi-steadyapproximation reduces to lineartemperature
Porous flow through cell walls
Henry’s law governing gasdissolution
Osmosis due to sugarconcentration differences

Mathematical Model – Macroscale
Then on an entire tree stem, we solve a macro-scale problem:
Cylindrical geometry
Mixed temperature-enthalpy formof the heat equation
Homogenization couples micro-and macro-scales:
integral source term in heatequationsolution-dependent thermaldiffusion coefficient

Basic Research Plan
Current state of affairs:
Multiscale model for free/thaw mechanism:captures physical processes on the cellular scale (coupledsystem of PDAEs)uses periodic homogenization to “up-scale” heat transport tothe tree stem (2D cross-section)gives new biological/physiological insights into the essentialprocesses governing exudationvalidated against controlled lab experiments on black walnut
Maryam: comparing numerical simulations to experiments onred/sugar maple (University of Vermont)
Bebart: PDE models for (1) transpiration-driven flow and (2)heat transport in a tapered tree stem – paper(s) in preparation
Isabell: just submitted a theoretical paper on homogenizationresults to IMA J. Appl. Math.

Future Plans
Continue experimental validation work, submit paper toTree Physiology (now)
Extend multiscale model to 3D, add taphole BC, applyvacuum pressure (1 yr)
Use models/codes to perform parameter studies and optimizesap yield under various harvesting and climate scenarios(2-3 yrs)
Apply to bigleaf maple: unclear whether freeze/thaw cyclesare required (2 yrs)
Extend to white birch: pressure is generated in roots, notstem (2-5 yrs)
More fundamental studies of sap flow, with and withouttranspiration (5+ yrs)

Tree Sap Industry
Sugar maple: 9.5M gals, $400M, 70% from QC (2014)
Bigleaf maple: <1,000 gals (Vancouver Island)10,000 times smaller!
White birch: ∼1,000 gals, 5× price (Alaska)
Odd features of maple (and other specialty) syrup industries:
Most are small family operations (individual “farmers”) ANDthey’re in remote areas.
A few industry associations have small amounts of research funding:NAMSC (1¢/container), OMSPA, Citadelle (?).
Any other funding comes from provincial agriculture agencies.
Potential for birch syrup production is enormous!

Identifying Potential Funders
Research granting programs:
Familiarize yourself with programs of NSERC, Mitacs, . . .
Talk to someone in your Office of Research Services. At SFU,check “databases” available athttp://www.sfu.ca/ors/fundingopportunities.html.
Do a Google search.
Industrial partners:
Mitacs: check internship projects list, contact a BusinessDevelopment Officer.
NSERC: check list of eligible partner organizations andfunders of CRD grants.
Read local newspapers and business magazines.
Do a Google search.

Writing Grant Applications
Consider similar questions as you would for journal papers,scholarships, etc.:
What do you propose to do?Why is it novel or important?How does it fit the program guidelines or objectives?Why are you the one to be doing this?Has the area been studied before? If so, what’s been done?Why do think your plan is feasible?What will you do if your initial approach fails?What resources and expertise are available at your institution?What special issues or constraints surround your specifictarget funding organization or program?

Grant-writing Tips
Follow instructions carefully, paying special attention toeligibility and budget requirements.
In particular, stick to formatting instructions: margins, fonts,headers/footers, page restrictions.
Make sure spelling and grammar are perfect.
Keep aims short/punchy, and use emphasis where needed.
Avoid acronyms and excessive technical terminology.
Include numbers and details, but don’t overdo it.
Try to leverage various sources of funds.
Keep your audience in mind!
Don’t include everything you want to do! Restrict yourself toa list that is doable/believable/exciting/relevant.

Basic vs. Applied Research
If you are applying for a grant from a government or industrialfunding source, then keep the following in mind:
There are surely some (many?) readers who won’t bespecialists in your field, or even scientists.
Funders are more concerned about deliverables: reports,software, concrete improvements to products or processes, . . .
Timelines tend to be shorter (months instead of years).
Intellectual property can be a major issue.
Your university may take an overhead cut: up to 25% inCanada, 50% in the USA.
Make sure that expectations regarding publication are clear.
If possible, discuss with an agency representative beforestarting your application.
An industrial grant application reads very differently from anacademic one!

Industrial Mathematics: Final Words of Advice
Just because you can apply for money (and succeed) doesn’tmean that you should.
When formulating objectives, include at least a few thatyou’ve nearly completed or else are easy to accomplish.(the dirty secret)
Knowing how to talk to industrialists is an acquired skill.
Aim for those funders that will permit you the freedom to doat least some fundamental research.
Try to turn any consulting opportunities into funding forstudents (avoids taxes). (Mitacs Accelerate internships)
