In recent years, with increased urbanization, the beneficial role of urban trees and forests has become critical for Canadian residents. Despite this recognition, there is little knowledge of the extent of urban forestry activities being performed across the country; one of the reasons for this is that urban foresry is happening under different labels. In […]

Most of the thermobarometric methods available to measure the pressure and temperature of metamorphism rely on the assumption of thermodynamic equilibrium and knowledge of the partitioning of elements between minerals. The pressure estimates obtained from these methods could be affected by chemical diffusion and/or variation in stress distribution, common during metamorphism. Furthermore, they also may […]

Crosswell seismic tomography is a geophysical survey method in which the propagation of sound waves through the Earth’s crust is used to infer geological structure. An array of acoustic sources and receivers are placed into separate boreholes, and full waveform recordings are made of the response to each source, measured at each receivers, the objective […]

Nitrate is a major contaminant of modern groundwater and terrestrial ecosystems. It is also involved in the generation and destruction of nitrogen bearing greenhouse gasses. In order to assess how nitrate is cycled in the Earth surface environment, as well as in recent Earth history , it requires the generation of pristine records that record […]

L’objectif général de ce projet est de développer une méthode de traitement électrolytique d’oxydation avancée (EOA) et d’optimiser son mode de fonctionnement pour le traitement d’eaux de rejets chargées en micropolluants bio-réfractaires tels que les effluents issus de l’industrie pharmaceutique. Ce procédé implique la mise en œuvre de la réduction de l’oxygène pour promouvoir le […]

Many of the Harrison River tributaries no longer support historic levels of salmon productivity because of barriers to fish passage, loss of in-stream structural complexity, and ingress of invasive species. The Sts’ailes Fisheries Group has identified the need for an investigation of the historic and current stream characteristic to identify future fisheries restoration opportunities along […]

L’exploitation souterraine par la méthode de la charge concentrée ou VCR (vertical crater retreat) consiste en la création d’un vide qu’on vient par la suite remplir par un matériau constitué d’un mélange de résidus miniers, d’un agent liant (ciment) et de l’eau. Ce matériau est appelé remblai en pâte cimenté. Ce dernier doit développer une […]

Li-ion batteries (LIBs) are currently the most important power source for a wide variety of applications such as cell phones, laptops, computers and other portable electronics. They are also considered as very promising storage/power systems for future electric/hybrid-electric powered transportation. Although clever cell design and improvements in cell subcomponents can bear potential for volume and […]

In the backcountry, avalanche risk is managed by first assessing avalanche hazard and subsequently carefully choosing terrain and travel procedures accordingly to mitigate the identified hazard. What are suitable terrain choices under different types of avalanche conditions and how are choices made? With this project, we quantitatively examine large-scale terrain choices in two commercial backcountry […]

Les gisements profonds sont exploités selon différentes méthodes de minage dépendamment de la qualité de la roche encaissante. Une des méthodes d’exploitation en souterrain la plus sécuritaire et la plus fiable est la méthode par chambre remblayée. Elle consiste à remblayer la chambre (chantier ouvert) qui contenait le minerai. Le remblai minier le plus efficace […]

In dendrochronology, tree-ring widths are used in environment and climate reconstructions. In addition to tree-ring width, wood anatomy and tree-ring anomalies are becoming increasingly valuable as sources of proxy data. The disruption of normal tree growth resulting in various tree-ring anomalies including frost rings, false rings or light rings have been related to climate events […]

E-waste is one of the fastest growing waste streams in the world in terms of volume and its environmental impact on the planet. Printed circuit boards represent a major portion of the e-waste that contains higher values. The metal fraction from the circuit boards is extracted for its value while the non-metal fraction is often […]
