    Identification and Quantification of Organic Selenium Species Produced by Microbiological Activity in Freshwater Environments

    Year: 2016, 2016
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): LeBlanc, Kelly Lynn, Thesis advisor (ths): Wallschlaeger, Dirk, Degree committee member (dgc): Evans, R. Douglas, Degree committee member (dgc): Belzile, Nelson, Degree granting institution (dgg): Trent University
    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

    Name(s): Creator (cre): Maya, Nicholas, Thesis advisor (ths): Metcalfe, Chris D, Degree committee member (dgc): Yargeau, Viviane, Degree committee member (dgc): Wallschläger, Dirk, Degree granting institution (dgg): Trent University
    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

    Why not give up? A study on the role of resourcefulness in goal pursuit

    Name(s): Creator (cre): Smith, Patricia, Thesis advisor (ths): Kennett, Deborah, Degree committee member (dgc): Summerfeldt, Laura, Degree committee member (dgc): Coughlan, Rory, Degree granting institution (dgg): Trent University
    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. My… more

    Bio-based Polymers from Epoxidized Vegetable Oils Modified by Metathesis

    Name(s): Creator (cre): Brinkmann, Beke, Thesis advisor (ths): Schaefer, James A., Degree committee member (dgc): Pond, Bruce A., Degree committee member (dgc): Nol, Erica, Degree granting institution (dgg): Trent University
    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

    Electrochemical Characterization of Giardia Intestinalis Cytochromes b5

    Year: 2016, 2016
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Yang, Zhen (Alice), Thesis advisor (ths): Rafferty, Steven P, Degree committee member (dgc): Vreugdenhil, Andrew J, Degree committee member (dgc): Saville, Barry J, Degree granting institution (dgg): Trent University
    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

    Name(s): Creator (cre): McMorrow, Erin, Thesis advisor (ths): Hurl-Eamon, Jennine, Degree committee member (dgc): Siena, Kevin, Degree committee member (dgc): Harris-Stoertz, Fiona, Degree granting institution (dgg): Trent University
    Abstract: <p>Many print sources from 1680 to 1730 depicted bawds and witches as figures of transgressive elderly femininity. They were often described as having roughly the same anti-social behaviour, age, and gender. Both witches and bawds were seen as seducing innocents into a life of sin, associating with the </p><p>devil, and acting lustful and unmotherly. Furthermore, they were… more

    In the Wilderness at Föhrenwald: Jewish Refugees in Occupied Upper Bavaria, 1945–47

    Name(s): Creator (cre): McPherson, Alexander, Thesis advisor (ths): Kay, Carolyn, Degree committee member (dgc): Andriewsky, Olga, Degree committee member (dgc): Cazorla Sánchez, Antonio, Degree granting institution (dgg): Trent University
    Abstract: <p>In 1945, few refugee cases were as complicated as those of the Jewish survivors of the Holocaust who found themselves stranded in defeated Germany but could neither return home due to antisemitic violence nor immigrate to most countries due to extant prewar visa restrictions. Between 1945 and 1947, some 150,000 Jews fleeing ongoing antisemitic violence joined them in American-occupied… more

    Name(s): Creator (cre): Nixon, Katrina Leigh, Thesis advisor (ths): Pond, Bruce A, Thesis advisor (ths): Patterson, Brent R, Degree committee member (dgc): Schaefer, James, Degree granting institution (dgg): Trent University
    Abstract: <p>Livestock predation by wild predators is a frequent and complicated issue, often cited as a significant factor in the decline of livestock production and justification for killing predators. Coyotes (Canis latrans) are the primary predators of sheep in Ontario. Some farms appear to be more susceptible to predation than others, despite the use of mitigation techniques. I explored land… more

    Correlating density of states features with localization strength in disordered interacting systems

    Year: 2015, 2015
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Perera, Jayanayana Lakmali, Thesis advisor (ths): Wortis, Rachel, Degree committee member (dgc): Atkinson, Bill, Degree granting institution (dgg): Trent University
    Abstract: <p>Johri and Bhatt found singular behavior near the band edge in the density of states as well as in the inverse participation ratio of the Anderson model. These singularities mark a transition to an energy range dominated by resonant states. We study the interacting case using an ensemble of two-site Anderson-Hubbard systems. We find the ensemble-averaged density of states and generalized… more

    Abstract: <p>Since the end of the Second World War, artists of Native descent have engaged with the Fine Art world where their work has come to be placed in the category of Native art. As a result of my journey, I have come to realize that in the Fine Art world the term Native art tends to be associated with the practices of our ancestors in times past obscuring our contemporary nature. In the… more

    Abstract: <p>Environmental factors play a critical role in the health and well-being of people worldwide and the distribution of the burden of disease associated with environmental causes is disproportionately high in marginalized populations, including First Nations. In this way, environmental health problems are as much social and political problems as environmental and must be addressed as such.… more

    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Ellington, Edward Hance, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Schaefer, James A, Degree committee member (dgc): Patterson, Brent R, Degree granting institution (dgg): Trent University
    Abstract: <p>My objective was to understand how individual variation, in conjunction with variation in habitat, can affect individual and population-level variation in animal space use. I used coyotes (Canis latrans) as a model species to investigate the roles of hybridization, an inherited intrinsic factor, and spatial memory, a learned intrinsic factor, on space use. I used a diversity of methods… more
