An experimental set up based on a diffusion bridge is developed to accurately determine the in-plane and through-plane permeability, Knudsen diffusivity and effective molecular diffusivity of gas diffusion layers used in PEFC. The parameters are estimated under various compression levels in...

Exploring how soil fungi can be used to restore native trees on reclaimed substrates containing petroleum hydrocarbons
DownloadSpring 2023
As part of reclaiming landscapes mined for bitumen, ecosystems must be revegetated to restore self-sustaining ecosystems in the boreal forest of western Canada. Current reclamation practices can involve the construction of large landforms, sometimes from overburden containing up to 8%...

Arsenic is a proven human carcinogen and associated with a myriad of other adverse health effects. This metalloid is methylated in human liver to monomethylarsonic acid (MMAV), monomethylarsonous acid (MMAIII), dimethylarsinic acid (DMAV), and dimethylarsinous acid (DMAIII) and eliminated...

Bacteria of the genus Lactobacillus can be found associated with plants, insects and vertebrate hosts, and their lifestyle can range from free-living to strictly host specific. Of the lactobacilli associated with vertebrates, the lifestyle of L. reuteri is particularly well understood. The...

Synthetic polymers are still widely used in today’s life despite all environmental issues attributed to them. Replacing synthetic polymers with natural biodegradable polymers has been considered as a way of reducing these environmental impacts partially, if not completely. Hydroxyporpyl xylan...

Long Term Dynamics And Potential Remediation Of Fine Textured Soils And Ground Water Contaminated With Chlorinated Organic Compounds And Salts
DownloadFall 2019
Contamination of land, water, and air is a widespread concern often associated with anthropogenic activities. Remediation of contaminated sites is necessary to minimize negative impacts on human health and the environment and allow for safe, productive use of land. Although contaminated sites...

Methane Production and Emission Mitigation in Oil Sands Tailings Concurrent with Hydrocarbon Degradation under Nitrogen Limited Conditions
DownloadFall 2020
Alberta’s oil sands generate large volumes of tailings from bitumen ore processing. These tailings ponds produce biogenic methane, which can be measured across 60-80% of the tailings surface. Based on current surface area data and emissions studies, tailings ponds could account for 8% of Canada’s...

Collins, Catherine Elizabeth Victoria
Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

Microbial biodeterioration of human skeletal material from Tell Leilan, Syria (2900 – 1900 BCE)
DownloadSpring 2011
Human bone is considered one of the most direct and insightful sources of information on peoples of the past. As a result, curation protocols have been developed to ensure that the integrity of human skeletal collections is maintained. Although collections are generally considered safe when these...
