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...

Regulation of digestive tract and progenitor cell homeostasis by intestinal bacteria in Drosophila melanogaster
DownloadFall 2020
The digestive tract facilitates nutrient uptake in the presence of a heterogenous cohort of symbiotic microbes. These microbes along with their collective genetic material form the intestinal microbiome and contribute to animal phenotypes. Similar to mammals, the microbiome of insects forms a...

Removal of model waste-water bacteria by magnetite in water and waste-water treatment processes
DownloadFall 2012
Conventional disinfection processes used for water and waste-water treatment such as chlorination, and ozonation produce disinfection by products which are carcinogenic. The use of magnetite as an alternative method of removing pathogenic microorganisms from the water streams was proposed as it...

The centrifugal particle mass analyzer (CPMA)-electrometer system has been proposed as an alternative method of calibration for devices that measure black carbon. This system is proposed to replace the current calibration standard of NIOSH 5040. The repeatability and intermediate precision of the...

Fall 2012
The size distribution, volatile mass fraction, effective density, mass concentration and mass-mobility exponent of particles from an inverted burner and a McKenna burner were measured with a Differential Mobility Analyzer (DMA) and a Centrifugal Particle Mass Analyzer (CPMA). Based on these...

A bacterial colony constitutes a complex microcosm which is equipped with a wide range of defensive adaptations that allow the colony to survive adverse environmental conditions and predation. The extreme resilience of bacteria in colonies has been a subject of continued research for nearly two...

Infectious respiratory diseases, caused by viruses and bacteria that attack the respiratory system, constitute a serious threat in public health around the world. Pathogens can be transmitted in the air though large droplets or aerosols. As aerosols can linger in the environment for a prolonged...

Fall 2013
The inactivation fluence of a target wastewater plant in Alberta, Canada was determined in the laboratory and was found to be close to that reported by the target wastewater plant. The effect of inactivation fluence, effective reactivation fluence, temperature, and river water on the percent...

Bacterial conjugation is the process of plasmid DNA transfer from a donor cell to a recipient cell. This process is mediated in F-like plasmids by proteins expressed by the tra operon. The relaxosome forms at oriT (origin of transfer), where the nicking and unwinding of a single-stranded copy of...

Study of Enhanced Deposition due to Magnetic Field Alignment of Ellipsoid Particles Using Direct Numerical Simulations
DownloadFall 2012
A recent in vitro study demonstrated a non invasive method to enhance local deposition in a small airway by controlling the angular position of magnetic high aspect ratio particles. This technique could mitigate the challenge of providing sufficient therapeutic effects when using aerosolized...
