Catalytic gasification of biomass for the production of syngas with reduced tar formation
(2009)With increased concerns over greenhouse gas emission and decreasing fossil fuel supplies, biomass is increasingly seen as an alternative option for energy and chemical production. There are several technologies available ... -
Catastrophe theory, symmetry breaking and the pseudo Jahn-Teller effect
(2019)This research focuses on the structural symmetry breaking observed in hypovalent silicon containing compounds. The structural symmetry breaking was studied from the perspective of the pseudo Jahn-Teller effect (pJTE). A ... -
A Century of change : documenting ecological landscape patterns in Northwestern Yunnan
(2009)This thesis provides a biogeographical analysis of the ecological landscape changes that have occurred in northwestern Yunnan over the past century. The practical purpose of this dissertation is to evaluate the major changes ... -
CFD Modeling of an activated sludge bubble column
(2017)The bubble columns are widely used in different industries such as wastewater treatment, chemical, petrochemical, and biochemical. The current design of the bubble columns including but not limited to the geometry and ... -
Challenges faced by young adult African students with Refugee Status in Ontario schools
(2014-12-05)This qualitative study explores the common challenges faced by African young adult refugee students in regard to their academic achievement in Ontario secondary schools. It also considers, using the participants' ideas and ... -
Changes in winter habitat use by mammals following commercial thinning of lodgepole pine (Pinus contorta) in west central Alberta
(2010)In 1996, Millar Western Forest Products initiated an adaptive management experiment to assess the potential benefits of commercial thinning and to monitor its effects on winter habitat use by multiple mammalian species, ... -
Changing subcultures from old roles to new identities : an analysis of gender through the emergence of women in drag racing / by Amanda R. Sundell.
(2009)This is a study in interpretive and critical sociology of the experiences of women in drag racing. The purpose of this study is to examine and give voice to women's gendered experiences in drag racing. The methodology ... -
Characteristics of connectivity between harvested landscapes and fixed-width riparian buffers
(2013-02-03)Fixed-width riparian buffers are a common best management policy enforced in forested landscapes on first and higher order streams. These buffer areas are delineated along stream banks in the field, based on the presence ... -
Characteristics of the boreal mixedwood forest associated with subnivean access by the American Marten (Martes americana)
(2012-11-10)Habitat selection by the American marten (Martes americana ), in studies throughout its range, has been associated with forest types that offer higher structural complexity. Such structure has been proposed to facilitate ... -
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 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 ... -
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 ... -
