Les changements climatiques entraînent une évolution de la répartition des cas de maladies transmises aux humains par les moustiques. Par exemple, le virus du Nil occidental, qui fait partie des préoccupations de santé publique au Québec. En étudiant le cycle de vie des moustiques, leurs habitats et les conditions météorologiques qui leurs sont favorables, il […]

Le lac Saint-Charles est un réservoir d’eau potable qui est soumis à un vieillissement prématuré qui est causé par l’accroissement de la population sur son bassin versant. Il en résulte une dégradation de la qualité de l’eau et de son intégrité écologique. Nous pensons que les eaux usées générées par les humains sur son bassin […]

Lamps and lighting products are the most commonly used electrical product around the globe. With the improvement in lamp technologies, from incandescent bulb to compact fluorescent lamp to LED bulbs, the products have grown complex and hence they require an improved recycling process. In general, lamps consist of various valuable metals such as iron, copper, […]

The efficient monitoring of soil and crop parameters is essential for crop stress evaluation and yield forecast in agriculture, yet most remote sensing studies focus on regional-scale soil and crop parameters estimation using satellite data. Satellite remote sensing is difficult to obtain both high spatial and temporal resolution data with a low-cost in field-scale. Currently, […]

The physicochemical character of the hydrological regime that formed Carlin-type Au-deposits (CTGDs) are poorly understood and represents a critical knowledge gap relating to their genesis. We are undertaking an integrated geological and geochemical study of the Nadaleen trend of CTGDs in the Yukon to better define the hydrological regime that controlled their formation. The proposed […]

The goal of this project is to develop instrumentation and software that will enable more efficient and safe mining practices. We will focus on the development of (1) vision-based instrumentation; (2) methods to increase situational awareness; and (3) techniques for automated data acquisition. This research will result in the design of a prototype vision system […]

Recent advances in hydrogeomorphology promote a sustainable, holistic approach to river management based on the concepts of working with nature, where mobility and flood zones are defined to give more space to rivers for fluvial processes and associated ecosystem services to operate. This sustainable and proactive restoration vision, termed “the freedom space for river” concept, […]

Copper and palladium (Cu-Pd) mineralization at the Marathon Deposit are associated with gabbro rocks. It is fundamentally important to be able to distinguish among the different types of gabbros, because only those of the Marathon Series are host to mineralization. This is accomplished through logging drill core, whole rock geochemistry and mineralogy. Mineralization at the […]

Nearshore marine ecosystems are undergoing change, with ecological, economical and cultural ramifications. Yet, we lack empirical understanding and observation of the nature of this change, over long periods of time and across continental coastlines. Additionally, the drivers of change in coastal systems are numerous: climatic forcing, predator recovery, and development of foreshore areas, amongst others. […]

Sudbury represents the site of a meteorite impact structure originally greater than 200 km in diameter and that formed 1.85 billion years ago. Despite the proven and potential economic benefits of resource development at Sudbury, there are still major outstanding questions concerning our understanding of the structure and its ore deposits. A series of objectives […]

Une grande partie des rejets produits par l’industrie minière est souvent entreposée en surface. En contact avec l’oxygène atmosphérique et l’eau, les minéraux sulfureux contenus dans ces rejets s’oxydent et génèrent un drainage minier acide (DMA) comportant des contaminants préjudiciables pour l’environnement. Une des techniques utilisées pour contrôler ce phénomène est les recouvrements à plusieurs […]

The regeneration of the moss layer after a disturbance has been studied in different ecosystems, for example in harvested and burned forests, in borrow pits for road construction, on mine tailings and in peatlands. Bryophytes play a key role in the soil formation, particularly in terms of the considerable amount of terrestrial biomass they represent […]
