L’état de santé des rivières qui se déversent dans le lac Saint-Charles, est peu connu. Grâce à ce projet de recherche, l’Association pour la Protection du Lac Saint-Charles et des Marais-du-Nord (l’APEL), en lien avec l’Université Laval, développera un indice qui permettra de classer l’état de santé des rivièrescomme étant excellent, bon, assez bon, pauvre […]

An emerging strategy for managing natural resources such as Canada’s forests more sustainably and responsibly is to use knowledge of how Mother Nature has done it to help guide our hand. This so-called ‘ecosystem-based” approach has gained favour with provincial and federal governments, as well as national and international certification agencies. One of the foundations […]

Blending carbonaceous materials with thermoplastic materials can lead to a significant improvement of the resulting electrical, mechanical, thermal, and gas barrier properties compared with the unfilled polymer. Graphene, the name given to a material consisting of two-dimension layers of carbon atoms arranged in a hexagonal lattice, has extraordinary properties which make possible to produce a […]

Unconventional shale gas has become a common source of hydrocarbons in the past few decades with advances in extraction techniques such as hydraulic fracturing and horizontal drilling. Many hydrocarbon-bearing rocks that were once unobtainable are now available for oil and gas production; the Nordegg Member in northeastern British Columbia is one of these rocks units. […]

Les barrages sont équipés d’évacuateurs de crue, dont le canal d’évacuation est la plupart du temps excavé dans le roc. L’écoulement intensif de l’eau peut conduire à l’érosion du roc, qui peut potentiellement affecter la stabilité des ouvrages hydrauliques. Afin d’assurer la pérennité de ses ouvrages hydrauliques, la compagnie Hydro-Québec souhaite disposer d’une méthode fiable […]
