D’après plusieurs données climatiques, on observe que les précipitations enregistrées au Québec augmentent considérablement de l’ouest vers l’est, et un peu moins du nord vers le sud. Connaissant le rôle majeur que jouent les feux dans la dynamique de la végétation en forêts boréales, nous nous interrogeons donc sur l’influence qu’auraient les variations climatiques en […]

This research will focus on using lakes sediments to determine the amount of marine derived nutrients and contaminants that Alewife (Gaspereau) transfer into Gaspereau Lake, Kings County, Nova Scotia. Lake sediment records form an archive that preserves environmental change that has occurred in lakes. In this project lake sediment cores will be collected and analyzed […]

NORAM Engineering and Constructors have a technology called salt splitting. This technology is used to produce caustic soda and sulfuric acid. However, the presence of fluoride in this technology can cause the breakdown of the coating on the titanium anode, which can cause premature anode failure. As replacing these titanium anodes can incur significant costs, […]

L’étude métallurgique est une étape essentielle de tout projet minier. Cette étape permet de concevoir un procédé afin d’extraire un métal d’intérêt (c.-à-d. l’or dans le cadre de ce projet) des roches. Ce procédé dépend des types de minéraux qui renferment l’or et tient compte des polluants que peuvent contenir ces minéraux. L’étude métallurgique s’appuie […]

Antimony is classified as a strategic element due to its high relevance for many military and technical applications, e.g. its use in fire suppressants and lead-acid batteries. Canada has currently no operational mine to produce antimony and about 90% of the world production originates from China and east Asia. This project will develop a geophysical […]

A two-year study on brazing technologies used for sintered tungsten carbide tiles is proposed to address the following technical objectives: 1) brazing metallurgy for sintered tungsten carbide and substrate high strength steel, 2) adherence mechanisms between different braze compositions and carbide tiles, 3) brazing parameters for optimized brazed joint performance, and 4) the mechanical stresses […]

Thus far Steam-Assisted Gravity Drainage (SAGD) has been the sole commercially viable in-situ recovery method to extract Canadian oil sands that are too deep for mining. It involves high pressure steam injection and bitumen production using horizontal well pairs located near the base of oil sands formations. While it has enabled conversion of significant resources […]

Chaque stade glaciaire modifie le paysage. Lorsque les glaces se retirent, le nouveau paysage émerge, le niveau marin augment et les eaux glaciomarines envahissent et submergent les anciens terrains glaciaires. Tracer la limite marine postglaciaire peut révéler d’importantes connectivités hydrologiques et des échanges entre les écosystèmes terrestres et marins qui ont eu lieu et qui […]

L’écologie de la reproduction de l’épinette noire dans les forêts nordique est peu compris. En particulier, il existe un manque général de données sur la production et la maturation des cônes / graines en fonction des variables climatiques, des caractéristiques abiotiques et des caractéristiques biotiques. Aucune étude n’existe actuellement pour quantifier ces différences sur un […]

Water is vital for life; it is a resource we interact with daily and rely on implicitly. Our reliance on water resources is why water pollution is a global concern. One risk to water quality is elevated levels of toxic trace metals. While metals occur naturally in aquatic environments, human activities can increase natural concentrations […]

The Mottled Duskywing is an endangered butterfly species in Canada. In order to reverse the decline of this species, research is required to fill in knowledge gaps regarding the species biology and life history. There are currently no data available on population size, survival rates of adult or juvenile life stages, dispersal, or optimal habitat […]
