Abstract: <p>Arctic terrestrial ecosystems have experienced substantial structural and compositional changes in response to warming climate in recent decades, especially the expansion of shrub species in Arctic tundra. Climatic and vegetation changes could feedback to the global climate by changing the carbon balance of Arctic tundra. The objective of this thesis was to investigate the influence of… more Year: 2016, 2016

Abstract: <p>Despite being an essential nutrient at trace levels, selenium can be devastating to aquatic environments when present in excess. There is no apparent correlation between total aqueous selenium concentrations and observed toxic effects because bioaccumulation varies over several orders of magnitude depending on the chemical species of selenium and the biological species present in the… more Year: 2016, 2016

Abstract: <p>Micropollutants are discharged into the aquatic environment with industrial and domestic wastewater and these compounds may cause toxic effects in aquatic organisms. In this study, the toxic effects to fish of micropollutants extracted from ozonated and nonozonated municipal wastewater effluent (MWWE) were measured in order to assess the effectiveness of ozonation in reducing toxicity.… more Year: 2016, 2016

Abstract: <p>Past research suggests that taking a process oriented approach, setting clear and concrete goals, and using both conscious planning and proactive coping are the best methods to be successful with goal pursuit. Also the literature has found that individuals scoring higher in general resourcefulness tend to be more successful at achieving goals than their less resourceful counterparts.

Abstract: <p>The epoxides of oligomeric self-metathesized soybean oil (MSBO) and cross-metathesized palm oil (PMTAG) and canola oil (CMTAG) containing terminal double bonds were used to produce nonisocyanate polyurethanes (NIPUs) as well as anhydride, amine and thiol-cured epoxies. </p><p>The synthesized NIPUs displayed metal adhesive properties for CMTAG and MSBO with MSBO being favoured… more Year: 2016, 2016

Abstract: <p>A species of concern is caribou (Rangifer tarandus), a species in decline across most of the circumpolar North, including the island of Newfoundland. Resource exploitation across caribou ranges is projected to accelerate in the coming decades as oil extraction, roads, forest harvesting, and mining encroach upon their habitat. Hydroelectric corridors, in particular, are anticipated to… more Year: 2016, 2016

Abstract: <p>Giardia intestinalis is a protozoan parasite that causes waterborne diarrheal disease in animals and humans. It is an unusual eukaryote as it lacks the capacity for heme biosynthesis; nonetheless it encodes heme proteins, including three cytochrome b5 isotypes (gCYTB5s) of similar size. Homology modelling of their structures predicts increased heme pocket polarity compared to mammalian… more Year: 2016, 2016

Abstract: <p>Interseeding legume cover crops in grain corn may improve the environmental sustainability of corn production system in Southern Ontario. This study aimed to assess the effects of legume species, nitrogen (N) fertilizer rate and arbuscular mycorrhizal fungi (AMF) inoculation on biomass and N requirement in a corn-legume system. Corn was grown with red clover (RCl), microclover (MCl),… more Year: 2016, 2016

The ontological question is elaborated in terms of a theory of the spatial-temporal structure of the aesthetic or sensible realm. This… more Year: 2016, 2016

The films being studied are El Sol del Membrillo by Victor Erice and Rivers and Tides by Thomas Riedelsheimer. My approach to critical topography in the thesis is twofold: first, I have traced the topical motifs that have appeared to me as I looked at the two films; second, I… more Year: 2016, 2016

Abstract: <p>Since British colonization of North America and the beginning of Anglo-speaking Euro-Canada and the United States, myth-making or representations of the forests have witnessed degradation and loss of old-growth forest ecosystems or intact sylvan landscapes. Canadian and American versions of the story of the North American Forests shared the same trajectory: forests as 'wasted-land… more Year: 2016, 2016

Abstract: <p>The aim of this work was to identify the DNA sequences recognized by the Giardia TBP (gTBP) in vivo by using a chromatin immunoprecipitation assay (ChIP). Since a specific antibody for the protein of interest is required for this assay, a company was contracted to produce and purify a custom polyclonal antibody from the immunization of rabbits. Recombinant GST-gTBP was produced at a… more Year: 2016, 2016

I used Redside Dace (Clinostomus elongatus) as a focal species to examine the utility of novel monitoring approaches, and to understand historical and contemporary processes that have influenced their present distribution.

Abstract: <p>The 1980s in the United States have come into focus as years of extensive ideological and socioeconomic fracture. A conservative movement arose to counter the progressive gains of previous decades, neoliberalism became the nation's economic mantra, and détente was jettisoned in favour of military build-up. Such developments materialized out of a multitude of conflicts, a cultural… more Year: 2016, 2016

Abstract: <p>The goal of the present study was to explore the overall discourse within media articles regarding Aboriginal health issues. The present research aimed to answer the following questions: What Aboriginal health issues are being discussed in the media? How are Aboriginal health issues being discussed in the media? And, does the media propagate power imbalances between Aboriginal and non-… more Year: 2016, 2016

Abstract: <p>Urban agriculture (UA) is becoming increasingly prevalent in Canadian cities. Despite this municipal zoning by-laws often do not address UA explicitly. Using eleven interviews of urban agricultural participants a case study of the City of Peterborough's zoning by-laws and the barriers they might present to UA was conducted. Research suggests that UA can provide many benefits to… more Year: 2016, 2016

Abstract: <p>This research considers the historic context of power that planning operates within, and looks at the ways in which certain community members are marginalized by traditional planning processes. Participatory planning, which has theoretical roots in communicative planning theory, may have the potential to shift the legacy of power and marginalization within planning processes, resulting… more Year: 2016, 2016

Abstract: <p>This thesis is intended to support dependent-on-crops farmers to hedge the price risks of their crops. Firstly, we applied one-factor model, which incorporated a deterministic function and a stochastic process, to predict the future prices of crops (soybean). A discrete form was employed for one-month-ahead prediction. For general prediction, de-trending and de-cyclicality were used to… more Year: 2016, 2016

Abstract: <p>Sustainable development is normative - making decisions in the present that construct the experience of place for the future. It is primarily driven by global measures developed to meet the needs of the present while ensuring future generations can meet their own needs. These measures attempt to balance economic prosperity, social justice, and environmental stewardship in many nations.… more Year: 2016, 2016

Abstract: <p>This study assesses the ability of a unicellular protist, Euglena gracilis, to remove Cu and Ni from solution in mono- and bi-metallic systems. Living Euglena cells and non-living Euglena biomass were examined for their capacity to sorb metal ions. Adsorption isotherms were used in batch systems to describe the kinetic and equilibrium characteristics of metal removal. In living systems… more
