E=ELIPATP
Experiment
Life science
The aerobic world relies on the presence of O2. When deprived of O2 for
an extended period of time, cell metabolisms experience serious and irreversible
effects, as is the case during transplantation, for example. I therefore
tried to reproduce cell ischemia, while ensuring that the cells remain
alive and that their metabolisms continue to function, by introducing
ATP liposomes.
Jean-Sébastien Sauvé

Our project consists of studying melittin, a small
peptide found in bee venom. I studied the way in which this molecule
destabilizes cell membranes, resulting in their destruction. I verified
the hypothesis that melittin creates holes.
Julie Désaliers
Fighting off the cold
Experiment
Life science
There are two types of wheat: winter wheat and spring wheat. After
conducting experiments at school and at UQAM, I observed that winter
wheat is more
resistant to cold. This difference is observed on a genetic level and
expressed through protein synthesis.
Guillaume Labbé and Éric Pouliot
A shower a day . . .
Experiment
Physical science
We built a reactor to eliminate the offensive odours produced by pulp
and paper plants. This reactor eliminates a gas (H2S) using a system
that resembles a shower. Since we succeeded in eliminating this gas,
our experiment was a success.

Applied science and technology
After observing a number of similarities between mathematical functions
and the concepts of artificial intelligence, I decided that the aim of
this project would be to use analogical reasoning to discover the extent
of these similarities, up to the level of differential calculus. A computer
program, Newton, applies these extraordinary discoveries, which have
the potential to correct errors.
Olivier Adam
Pendulum . . . pendulum . . .
Experiment
Physical science
Since chaotic behaviour occurs in the case of forced oscillation, I asked
myself the following question: Are forced oscillations, governed by the
equation x” + Bx’ + P(x) = S(t), subject to the same chaotic
behaviour? I will begin by studying pendulum theory and then analyze
the chaotic behaviour of pendulums.
Guillaume Roy and Pierre-Laurence Marchand

Is it possible that each part of a plant forms a highly complex architectural
and mathematical arrangement? How is this arrangement formed? Why does
this phenomenon occur? These are the questions that piqued my curiosity
and led me to present a project on plant phyllotaxy.
Isabelle Côté and Isabelle Raiche
What’s in your milk?
Experiment
Physical science
We conducted an experiment that demonstrated the usefulness of pasteurization.

Membrane receptor
Experiment
Life science
Green Fluorescent Protein (GFP) has the property of emitting green light.
This characteristic enabled us to use it to observe the cell location
of the TGF-ß type I receptor by combining it with a protein that
tolerates fusion: GFP. To do so, we will construct a molecule (containing
the receptor fused with GFP) and transfect it to Cos-1 and L-17 cells
in order to observe these cells using fluorescence microscopy.
Dave Barriault and Michel Boulianne
Creating water
Experiment

Since we chose to discuss the creation of water, we had to create some.
Using two simples processes—photosynthesis and the chemical reaction
between an acid and a metal—we obtained two gases: dihydrogen and
dioxygen. We used a spark to produce a reaction that enabled us to create
the final product. This report contains a short history of Lavoisier,
the aim of this experiment, the protocols used for each step of the experiment
and a discussion.

The secret’s in the bowl
Experiment
Life science
On the basis of the law of conservation of mass formulated by the
chemist Antoine Laurent Lavoisier stating that “the mass of the
reactants is equal to the mass of the products”, we formulated
the following hypothesis: If the mass of the reactants is equal to the
mass of the products, a living plant in an enclosed space should be able
to meet its essential needs. To support our hypothesis, we observed the
development of green plants in an enclosed and an open space over several
months.
