Les barrages hydroélectriques permettent de fournir une énergie renouvelable. Leur construction implique d’inonder une vaste zone en amont du barrage. Le fait d’inonder un territoire engendre des émissions de gaz à effets de serre dans l’atmosphère. Calculer le bilan carbone des réservoirs hydroélectriques implantés en forêt boréale est difficile, puisque les forêts sont affectées régulièrement […]

The overall goal of our work is to use novel genetically modified rodent models to determine how two gene regulatory proteins known as ‘TIPARP’ and ‘AHR’ interact to influence mammalian responses to an important class of chemical toxicants that are found in certain foods and in the environment. These include the potential pesticide contaminant dioxin […]

In Canada’s mountains, climate change is leading to the retreat of glaciers, permafrost thawing and accelerated snowmelt. These factors contribute to a significant increase in slope stability hazards and the risk of landslides, placing numerous communities and critical infrastructure at risk. Volcanoes are particularly vulnerable as they are commonly hydrothermally altered and weakened, thereby compounding […]

What effect do urban trees have on the livability in our cities? What is the economic value of a single urban tree and which ecosystem services does it provide? Where are potential hot spots of invasion by forest invasive alien species? These and many more questions about urban trees are becoming increasingly prominent due to […]

Characterization of the energy distribution of ions generated by the plasma in an Inductively Coupled Plasma Mass Spectrometer (ICP-MS) instrument is necessary for a new ion source in that it influences the ion sampling process, transmission efficiency, focusing, and mass analysis in ICP-MS. These energy distribution phenomena are also analogous to the ion beam that […]

Air quality is a major issue worldwide and has both health and cost implications. Major concerns deal with health issues due to noxious effects of nanoparticles and gaseous pollutant emitted by road traffic (including cardiovascular diseases, enhancement of allergies, pulmonary diseases etc.).It is well-know that transportation systems are a major contributor to pollutant emissions, being […]

Dans le cadre de mon mémoire de maîtrise, j’entreprends d’étudier la contribution capitale apportée par le philosophe, mathématicien et physicien allemand, Gottfried Wilhelm Leibniz, au problème métaphysique de l’application des mathématiques aux phénomènes réels. L’intérêt de ce projet est à la fois historique : donner une image fidèle de la pensée du philosophe d’Hanovre sous […]

Ring-billed gulls (Larus delawarensis) living in the metropolitan area of Montreal (QC, Canada) have been documented to be highly exposed to a class of industrial and potentially toxic contaminants, the halogenated flame retardants (HFRs), that might also negatively affect humans. Interestingly, those gulls showed intraspecific variations in tissular concentrations in HFRs, related to their foraging […]

The overall objective for this project is to support the research of two master’s students who would help advance the methods for modelling energy-climate policies, a field in which EMRG in the School of Resource and Environmental Management at SFU is one of the leading research units in the country and in which Navius Research […]

During this internship, my goal is to create a dinitrogen molecule that fits into the frustrated Lewis pair model. This molecule will be used to replace currently existing polluting fertilizers. To achieve this goal, the internship is divided into three steps: -The first consists of synthesizing a molecule containing N2. -Next, we will try to […]

Numerical simulation is a cornerstone of modern science and industry, and is used in many facets of our everyday lives. While many of us are familiar with short-term weather forecasting, substantially more computational effort is dedicated to longer-term simulations of the Earth’s ocean and atmosphere, for climate and other reasons. In such simulations, certain properties […]

According to evolutionary biology, adaptation of a population to a new environment results from an equilibrium between various trends. Adaptation is shaped by selection forces, such as fecundity, mortality and competition for resources, by migration, and by the generation of diversity at reproduction. The type of reproduction, whether it is mainly clonal (asexual) or it […]
