Characterization and utilization of fly ash derived from the co-combustion of biomass and coal as a mineral admixture for ordinary Portland cement
(2009)Co-firing coal with renewable/waste biomass for power generation can mitigate the atmospheric discharge of pollutants (e.g., SO2) and green-house gases. Wide-spread application of this technology is impeded, however, by ... -
Characterization of an arsenite-oxidizing caballeronia sp. soil bacterium and its mutualistic relationship with trifolium pratense for arsenic remediation
(2021)The proposed application of the mutualistic interaction between a native arsenicoxidizing soil bacteria and Trifolium pratense in Northwestern Ontario mine sites is a novel approach to remediation. This thesis studies the ... -
Characterization of CdZnTe semiconductor for applications in advanced computed tomography
(2017)Cadmium zinc telluride (CdZnTe) is currently the only single crystalline semiconductor used in direct conversion gamma-cameras since CdZnTe can operate at room temperature, unlike other materials (e.g., germanium) that ... -
Characterization of novel cellulase and glucose isomerase-producing bacteria and optimization of the enzyme production conditions and their potential applications in environment and industry
(2022)Cellulases and glucose isomerases are vital enzymes in converting cellulose into fructose. Cellulases catalyze cellulose conversion to glucose, while glucose isomerase catalyzes the reversible isomerization of glucose ... -
Characterization of rainbow trout (Oncorhynchus mykiss) and fathead minnow (Pimephales promelas) cell lines as models to study pulp and paper effluent effects in fish
(2012-11-10)The effects of aquatic toxicants on fish growth and development have been well-documented, in contrast to the changes in gene expression that necessarily precede them. Many of these toxicants are exogenous compounds that ... -
Characterization of rooting patterns in mixedwood forests of white spruce and trembling aspen: Is competition reduced belowground?
(2012-11-10)This study examined the rooting patterns of white spruce (Sw, Picea glauca (Moench) Voss) and trembling aspen (Pt, Populus tremuloides Michx.), and the effect of stand type upon such patterns. Specifically, contrasts were ... -
Characterization of sediment, sewage and 0157 E. coli: a comparison of their virulence genes, biofilm forming capacities, antibiotic resistance and level of reactive oxygen species (ROS)
(2018)Even though sediment Escherichia coli is a common source of contamination in freshwater environments, their virulence and physiological characteristics are not well studied. The goal of this study was to compare the virulence ... -
Characterization of the MAX porphyry Mo deposit using trace element geochemistry in hydrothermal alteration minerals, Trout Lake, B.C.
(2016)Over the last few decades it has become increasingly difficult to discover new ore deposits and as existing deposits are exhausted, techniques for improving exploration success are becoming vital. In this study I ... -
Characterizing the flow regime in Brook Trout (Salvelinus fontinalis) incubation habitats and the implications for management in a hydro-regulated river
(2018)Hydropower accounts for more than one third of Ontario Power Generation’s electrical production. Hydroelectric development often occurs on rivers that also support recreational fisheries. The construction and operation of ... -
Characterizing the microbial degradation of kraft lignin and lignin-derived compounds
(2014-12-12)Analytical methods for characterizing the microbial degradation of Kraft lignin and lignin-derived compounds were utilized with the goal of biologically generating demethylated lignin for subsequent industrial applications. ... -
Charcoal in North American boreal forests: implications for carbon storage and management
(2014-01-22)Charcoal plays an important role in boreal soil function and carbon storage, and is present in most boreal forest soils as a result of naturally recurring wildfires. Charcoal management has been proposed as a potentially ... -
Chemical and electrochemical modification of kraft lignin to value-added products
(2012-11-10)Lignin is one of the most abundant biopolymers on earth, constituting approximately 30% of the dry weight of softwoods and 20% of hardwoods. It is a renewable, non-toxic, commercially available and low cost natural resource ... -
Chemical de-polymerization for reuse of polyethylene terephthalate (PET) towards a circular economy
(2022)Sustainable and effective waste management is very important to address environmental pollution. This is especially the case for plastics as their inherent resistance to breakdown leads to their accumulation the environment. ... -
Chemoreception in invasive rusty crayfish (Orconectes rusticus): learning and adaptation in aquatic ecosystems of Northwestern Ontario
(2012-11-10)Crayfish utilize chemosensory cues, in addition to other sensory inputs, to mediate a variety of fundamental life processes. Exotic species, like the rusty crayfish (Orconectes rusticus), are known to employ a broader ... -
Childhood adversity and functional impairment in emerging adulthood: the role of executive function
(2021)Emerging adulthood (EA; ages 18-29) is a unique developmental period when individuals transition from their teenage years into adulthood, experiencing increased demands associated with independence. For some, there are ... -
Children with an identified learning disability and their understanding of the social world
(2012-11-10)Social skills are learned behaviours. Individuals with identified learning disabilities frequently have difficulty demonstrating, acquiring, and understanding the importance of behaviours that are deemed social skills and ... -
Children’s views of the learning environment: a study exploring the Reggio Emilia principle of the environment as the third teacher
(2016)The purpose of this research study was to explore the concept of the environment as the third teacher and how students in a Reggio Emilia inspired school view their classroom and its ability to help them learn. The research ... -
