Catalytic decomposition of ammonia and tar for hot gas cleanup in biomass gasification using activated carbon supported catalysts and natural limonite ores
(2009)Biomass gasification produces a gas (or syngas) containing primarily CO2, H2, CO, CH4 and (C2+C3), as well as some contaminants such as tars, NH3, H2S and SO2. In order to achieve better efficiencies of the syngas applications, ... -
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 ... -
Causes and consequences of population changes in Black Bay Steelhead, Lake Superior
(2019)Understanding species interactions is an important component of fisheries resource management. Like the other Great Lakes, Lake Superior’s fish species composition (and therefore interactions among species) has been changing ... -

(2020)"The CCF is not a 'Class' Party”: Labour and Politics at the Lakehead, 1944-1963” is a study of the organized labour movement in the Lakehead from 1944 to 1963. This study analyzes the new sophistication of the organized ... -
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 ... -
Challenged by compassion: an exploration of the lived experience of compassion fatigue among Canadian nurses who worked during COVID-19
(2023)The experience of compassion fatigue is a serious challenge within caregiving professions. Scholars agree that although the symptoms of compassion fatigue are similar to burnout and secondary stress disorder, there is ... -
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 ... -
Characteristics, functions, and body investment of non–suicidal self–injury in individuals of Middle Eastern and European ethnicity
(2021)The objective of the study was to investigate differences in non–suicidal self–injury (NSSI) characteristics, NSSI functions, and body investment for individuals of Middle Eastern and European descent recruited from ... -
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 alteration and mineralization of the Moss gold deposit, Shebandowan greenstone belt, Northwestern Ontario
(2024)The Moss Au deposit is an orogenic-style gold deposit hosted in felsic to intermediate rocks of the western Shebandowan Greenstone Belt, close to the terrane boundary between the Wawa-Abitibi terrane and the Quetico ... -
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 ...
