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...

Modeling the transport of cryoprotective agents in articular cartilage for cryopreservation
DownloadSpring 2011
Loading vitrifiable concentrations of cryoprotective agents is an important step for cryopreservation of biological tissues by vitrification for research and transplantation purposes. This may be done by immersing the tissue in a cryoprotective agent (CPA) solution, and increasing the...

The Dual Failure Restorability (DFR) problems involve the design of network topology to be restorable in the event of single and dual failures scenarios. We developed new integer linear programming (ILP) models to optimally design mesh topology networks with various survivability schemes; span...

Nano-scale studies of the assembly, structure and properties of hybrid organic-silicon systems
DownloadFall 2011
Advancements in the field of electronics might be achieved by future molecular scale devices. Hybrid organic-silicon structures have the potential to overcome many challenges facing the use of molecules as devices while maintaining the ability to interface with traditional silicon technology. The...

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...

Fall 2009
An agricultural land was adversely affected by salt released by the oil and gas industry. Remediation was needed to recover the land to agricultural productivity. Field-scale and laboratory-scale experiments were conducted to identify a practical and reliable remediation technique that could be...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...

This study examines the effects of Pseudomonas aeruginosa (PAO1) biofilm, with a concentration of cells similar to that reported for saturated aquifers, on the transport of poly(acrylic acid) stabilized nanoscale zero valent iron (pnZVI) in 14 cm long, saturated, laboratory packed columns, with...
