Biodegradation of Hydrocarbons in Bitumen: Exploring Plant-Assisted and Microbial Stimulation Techniques
DownloadFall 2020
While bitumen is one of the oldest construction materials in the world and currently provides an important fuel needed to sustain our modern lifestyle, the disturbances caused by extracting and refining this material are considerable, with 895 km2 of land being disturbed in Alberta as of 2018...

Can caffeine alter blood potassium concentration or the perception of pain and fatigue after a 1 km cycling sprint?
DownloadSpring 2013
Caffeine is used by some athletes to improve endurance performance, however, the mechanism(s) by which caffeine elicits performance improvements have been unclear. The purpose of this study was to investigate the effects of caffeine on pain perception, fatigue perception, plasma catecholamine...

Canadian Writers, McClelland & Stewart, and the Paperback Book: Remediation, Publishing, and Cultural Context
DownloadSpring 2014
This dissertation analyzes the relationship between literature and new media through an investigation of the book in a Canadian context and draws on book history and new media studies. To better understand the relationship between print and digital forms of publishing, I look backwards to a...

Coupled effects on the transport and deposition of biocolloidal particles in saturated porous media
DownloadSpring 2016
The transport and deposition of biocolloidal particles in porous media is a crucial phenomenon in understanding environmental challenges from pathogen contamination to bioremediation of soil and water. The fate and transport of biocolloidal particles in porous media is influenced by many factors...

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%...

Spring 2022
Coal is mined for energy generation around the world, resulting in extensive disturbances to soil health and vegetation, and producing large amounts of waste. Heavy metals enter the environment through coal industry activities before being transmitted to the food chain. Reclaiming post mining...

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...

Remediation of bitumen-contaminated sand grains: development of a protocol for washing performance evaluation
DownloadSpring 2010
In the development of a non-aqueous bitumen extraction process, a major obstacle is solvent loss due to hydrocarbon attachment to the reject sand grains. A proposed solution to this problem is to wash (i.e. remediate) the oil-contaminated sand grains with water and surfactants. This research is...
