The warm vaporized solvent injection process has been proposed as a more environmentally friendly alternative to steam-based technologies for bitumen recovery. The process typically involves injecting heated solvent vapor into a horizontal injector; the solvent condenses and dissolves into...

Application of manure from cattle fed with different diets affects soil properties and greenhouse gas emissions
DownloadSpring 2019
Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

Beyond mountain pine beetle: soil carbon storage a decade after tree mortality and the possible influence of soil fungi
DownloadSpring 2024
Mountain pine beetle (MPB; Dendroctonus ponderosae) disturbances, amplified by climate change, have led to extensive tree mortality and ecosystem succession in boreal forests across western Canada. Often following attack, former ectomycorrhizal (EM) pine stands in Alberta are replaced by...

Biodiversity of soil arthropods in a native grassland in Alberta, Canada: obscure associations and effects of simulated climate change
DownloadFall 2013
Soils have traditionally been treated as a “black box” due to the challenges of studying this complex medium. The living component of soil consists of a complex network of roots and mostly very small, highly abundant, and extremely diverse group of microbes, protists, and other invertebrates. In...

I investigated cellular mechanisms of ion and acid-base transport in rainbow trout (Oncorhyncus mykiss), crabs (Neohelice granulata), zebrafish (Danio rerio), Pacific hagfish (Eptatretus stoutii), and mosquito larvae (Aedes aegypti) with a primary focus on discerning the mechanisms governing ion...

Conductive Atomic Force Microscopy Study of Electron Transport Through Diazonium Derived Films and Mixed – Mode Bonded Layers on Gold and Carbon Surfaces
DownloadSpring 2012
For Molecular Electronics to become a viable replacement or complitment to current elec- tronic devices a fundamental understanding of device operation and functionality is needed. This work explores electron transport through diazonium derived molecular junctions via conductive atomic force...

Effects of long-term nitrogen and sulfur deposition on soil microbial communities and soil properties in the Athabasca oil sands region in northern Alberta, Canada
DownloadFall 2016
Intensified oil sands activities have resulted in elevated levels of nitrogen (N) and sulfur (S) deposition in the mixedwood boreal forest in the Athabasca oil sands region (AOSR) of northern Alberta, Canada. The deposition of N and S can affect the surrounding ecosystem and it is important to...

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...

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...

Influence of Soil Cap Depth and Vegetation on Reclamation of Phosphogypsum Stacks in Fort Saskatchewan, Alberta
DownloadSpring 2013
This study quantified environmental parameters to develop reclamation strategies for phosphogypsum stacks. Research was conducted on phosphogypsum stack experimental plots established in 2006 (6 soil cap depths, 5 vegetation treatments), and soil capped slopes seeded in 1998. Significant root...
