Mines generate large quantity of tailings. In most cases, they are transported by pipes and deposited in tailings ponds and confined by dams. To limit the footprint and land area of tailings pond, the dams have to be uplifted progressively with the increase in the tailings level. Several methods exist to uplift the tailings dams. […]

Cette demande porte sur les changements de végétation anticipés sous l’effet des changements climatiques, à la jonction entre le domaine de la sapinière à bouleau jaune (forêt tempérée) et celui de la sapinière à bouleau blanc (forêt boréale) (Figures 1 et 2). Nous quantifierons les différences entre le climat actuel et celui qui prévaudra dans […]

Le recyclage des enrobés bitumineux gagne en popularité. Cette procédure permet de réhabiliter les chaussées flexibles dans un esprit de développement durable. Ce projet de recherche porte sur l’influence d’ajout de granulats bitumineux recyclés (GBR) dans des enrobés neufs. Plus précisément, l’impact de l’ajout de GBR sur la rigidité et sur la résistance à fatigue […]

Brown marmorated stink bug (BMSB) (Halyomorpha halys (Stål)) is an invasive pest with a large host range that includes many economically important fruits, vegetables, and row crops. Native to Asia, BMSB was first detected in North America in 1998 and since has become established in British Columbia, Quebec, and Ontario; and 44 American states. In […]

Lake St. Charles is the primary drinking water reservoir of Quebec City, Canada, providing water to about 300,000 people. Over the past decade, several occurrences of blue-green algae (cyanobacteria) bloom have been recorded, affecting the quality of water in this strategic reservoir. Evaluation of observed data collected over the past decade indicates that the water […]

Mounting evidence shows that boreal and mountain forests are not solely driven by high severity fires that kill most of the above-ground vegetation (i.e. stand-replacing fires). Indeed, wildfire severity can be highly heterogeneous, leading to spatially complex forest landscapes, with multiple species and uneven ages. Many existing fire dynamics models do not explicitly consider the […]

Prairie wetlands are intricately linked with climate and hydrology. Future climate change, such as warmer conditions, changes in precipitation amount and intermittency, may both benefit and threaten the wetlands over the Canadian Prairies. During the same time, large-scale land use changes have been occurring such as the conversion of natural wetlands to agriculture lands. Understanding […]

While technologies exist for cleaning up marine oil spills, they become decreasingly effective with increased lag-time between spill and initiation of remediation efforts. Rapid-deploy chemicals could potentially reduce the spreading of marine oil spills, increasing the time available for teams to clean it up. The hybrid spill-treating agents (STAs) under development by BC Research Inc. […]

The proposed research project falls within what is called process intensification (PI). PI consists in novel devices and techniques that bring striking changes to chemical engineering processes by significantly decreasing the equipment’s size to production ratio, energy consumption and waste production, which result in smaller, cheaper, cleaner and more efficient technologies. Catalytic nanoparticles, with a […]
