Spring 2016
The study of methanogenesis in wastewater biofilms and various aggregated methanogenic environmental samples with high spatial resolution can be achieved by using microbiosensor techniques. In this study, the fabrication of a microbiosensor for methane detection was studied. This microbiosensor...

A Multi-Objective Optimization Workflow for Steam-Alternating-Solvent Heavy Oil Recovery Process Design
DownloadSpring 2020
Coimbra Paniagua, Luis Eduardo
The steam alternating solvent (SAS) process involves multiple cycles of steam and solvent (e.g. propane) being injected into a horizontal well pair to produce the heavy oil. Companies are interested in these solvent-based methods, as they entail a smaller environmental footprint with reduced...

Antimicrobial applications of treatments using light pulses emitted from light emitting diodes (LED)
DownloadSpring 2022
Low water activity (aw) foods have been associated with several foodborne outbreaks and recalls. Eradication of foodborne microorganisms like Salmonella and Escherichia coli from low aw foods is challenging, as they are resistant to conventional decontamination practices. High intensity light...

Fall 2021
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...

Spring 2017
One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...

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...

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...

Determination of biokinetic parameters of wastewater biofilms from oxygen concentration profiles
DownloadFall 2011
The process of scale-up and rational optimization of biofilm processes for effective wastewater treatment and reuse require better understanding of the biokinetic behavior of microorganisms in the biofilms. At present, no fast and accurate methods exist for determining kinetic parameters for...

Fall 2011
Microelectrodes can be used for profiling environmental biofilms. Currently there is no sulfate microelectrode available for studying sulfate reduction in biofilms. In this study, a sulfate microelectrode was fabricated and tested in measurement of environmental biofilms for the first time. The...

Development of Solvent Selection Criteria Based on Diffusion Rate, Mixing Quality, and Solvent Retrieval for Optimal Heavy-Oil and Bitumen Recovery at Different Temperatures
DownloadFall 2015
Heavy-oil and bitumen recovery requires high recovery factors to offset the extreme high cost of the process. Attention has been given to solvent injection for this purpose and it has been observed that high recoveries are achievable when combined with steam injection. Heavier (“liquid”) solvents...
