Solar Ultraviolet Radiation and Breast Cancer Risk
Background: A moderate amount of time spent in the sun has been hypothesized to be protective against several internal cancers, including breast cancer. This project summarized and synthesized existing literature on this ... -
“Planned to bring life back into living”
This thesis examines East Kilbride between 1968-1979. East Kilbride was the first New Town in Scotland, a postwar reform initiated by the British government in 1946 to relocate residents of Britain’s over-crowded cities ... -
Types and Number of Traumas Associated With Suicidal Ideation and Suicide Attempts in PTSD: Findings From a U.S. Nationally Representative Sample
(2015-06)Posttraumatic stress disorder (PTSD) is associated with suicidal ideation and suicide attempt; however, research has largely focused on specific samples and a limited range of traumas. We examined suicidal ideation and ... -
Exploring Physical Activity Opportunities for Adolescents in Secondary Schools in Antigua
Despite the known benefits of physical activity (PA), only 22% of adolescents in Antigua are meeting the World Health Organization’s (WHO) 60 minute a day moderate to vigorous physical activity (MVPA) guidelines (Aguilar-Farias ... -
The Development and Use of a Test Facility for Large Diameter Pipes
This thesis examines the performance of a new deep burial facility through numerical modelling and physical experiments. A numerical investigation was conducted to investigate the influence of the loading scheme and boundary ... -
Targeted Messages Increase Dairy Consumption in Adults: a Randomized Controlled Trial
(Oxford University Press (OUP), 2017-02-01)Background Dairy consumption amongst North Americans aged 30–50 has been declining. Targeted messages have been identified as a cost-efficient method through which to increase health-enhancing behavior, such as dairy intake. ... -
Substructuring verification of a rear fuselage mounted twin-engine aircraft
(Elsevier BV, 2019-10-01)Dynamic substructuring allows for the reduction of large complex structures into substructures to increase computational efficiency and to isolate the local dynamic behaviors of concern. However, errors such as truncation, ... -
A mechanism and thermodynamic model for the interaction of silicate minerals with lead-assisted gold electro-oxidation in a dilute cyanide medium
(Elsevier BV, 2019-07-22)Gold (Au) oxidation kinetics in cyanide (CN) solutions can be increased by the addition of low concentrations of aqueous lead [Pb(II)]. However, the Pb(II) addition is not always effective in improving Au oxidation kinetics. ... -
Phase transformation and microstructural changes during the hydriding and aging processes in dual phase Zr alloy
(Elsevier BV, 2019-06-01)The Zr-2.5 wt%Nb alloy was studied in order to elucidate phase transformations and the distribution/redistribution of hydrogen. The study focuses on understanding the stability of the ZrH system; surface hydride formation ... -
Transparent Omniphobic Coating with Glass-Like Wear Resistance and Polymer-Like Bendability
(Wiley, 2019-07-02)Transparent omniphobic or anti-smudge coatings with glass-like wear resistance and polymer-like bendability have many potential applications but there are no reports of such materials. We Report herein a molecular composite ... -
Hays Gone By: The Proto-Feminism of Pre-Code Hollywood and the Films of Mae West
Pre-Code Hollywood has famously been described as an alternative universe of American cinema, as looser censorship restrictions allowed filmmakers to explore adult themes of violence and sexuality far more openly than would ... -
Study of Back-Stress and Void Damage in Dual Phase Steels Subjected to In-Plane Shear
The objective of this thesis is two-fold: to study the relationship between microstructural parameters and the work hardening and back-stress that develops in dual-phase (DP) steels using an in-plane shear test, and to use ... -
A Study of Immigrant International Medical Graduates’ Re-Licensing in Ontario: Their Experiences, Reflections, and Recommendations
This study is about the lived re-licensing experiences of immigrant international physicians in Ontario who are commonly referred to as International Medical Graduates (IMGs). The study had a two-fold purpose, the first ... -
Vocal behaviour of Song and Swamp sparrows upon arrival on shared breeding grounds
Closely related species interact often, typically competitively, aggressively, and asymmetrically, with a consistent dominance hierarchy among species. Competition for resources appears to be a rate-limiting step in ... -
The Multidimensional Forgiveness Inventory: Developing a Dimensional Measure of Forgiveness
The present research sought to develop a dimensional model of forgiveness, and develop a questionnaire consistent with this model. Drawing from the tripartite theory of attitudes, this dimensional model focused on three ... -
Evaluating the relationship between the RET receptor tyrosine kinase and TMEM127
Pheochromocytomas (PCC) are highly heritable neoplasms of the adrenal gland, carrying germline mutations in approximately 40% of cases. PCC susceptibility genes have been subdivided into two clusters: hypoxia-related genes, ... -
Dielectric Resonator Antenna on Printed Circuit Board
With the increased demand for high efficiency wireless communication systems, there is a requirement to develop the antenna systems that are effective and dependable. Instead of a traditional metallic antenna, a dielectric ... -
Polymeric Liquid Behavior in Oscillatory Shear Flow
One of the great challenges in chemical engineering is to predict physical properties from molecular structure. Predicting transport properties presents special challenges, especially for macromolecular structures. This ... -
Uncharted Paths: The Use of Traditional, Complementary and Alternative Medicine (TCAM) among Sub-Saharan Africans living in the Greater Toronto Area (GTA)
The appeal of traditional, complementary, and alternative medicine (TACM) is growing among persons living in developed countries. Personal beliefs and traditional values about health and healthcare are deemed significant ... -
