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 Full Text: ELECTROCHEMICAL CHARACTERIZATION OF GIARDIA INTESTINALIS CYTOCHROMES b5 A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Masters of Science in the Faculty of Arts and Science TRENT …

Abstract: <p>The present thesis explores the cold flow properties of biodiesel and the effect of vegetable oil derived compounds on the crystallization path as well as the mechanisms at play at different stages and length scales. Model systems including triacylglycerol (TAG) oils and their derivatives, and a polymer were tested with biodiesel. The goal was to acquire the fundamental knowledge that… more Full Text: MITIGATING COLD FLOW PROBLEMS OF BIODIESEL: STRATEGIES WITH ADDITIVES A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Doctor of Philosophy in the Faculty of Arts and Science 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 Full Text: WITCHES AND BAWDS AS ELDERLY WOMEN IN ENGLAND, 1680-1730 A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Arts in the Faculty of Arts and Science.

Abstract: <p>This thesis explores the use of 1-butene cross metathesized palm oil (PMTAG) as a feedstock for preparation of polyols which can be used to prepare rigid and flexible polyurethane foams. PMTAG is advantageous over its precursor feedstock, palm oil, for synthesizing polyols, especially for the preparation of rigid foams, because of the reduction of dangling chain effects associated with… more Full Text: Synthesis of Lipid Based Polyols from 1-butene Metathesized Palm Oil for Use in Polyurethane Foam Applications A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Doctor of Philosophy in the Faculty …

Abstract: <p>This thesis investigates the organization and development of water management systems in a sample of past tropical societies in Southeast Asia and Mesoamerica. A comparative approach is employed to show how water management affected the trajectories of the ancient states of Angkor, Cambodia, Bagan, Myanmar, Sukhothai, Thailand, Central and East Java, and Caracol, Belize. Differing types… more Full Text: WATER MANAGEMENT AMONGST THE ANCIENT STATES OF CAMBODIA, MYANMAR, THAILAND, JAVA AND BELIZE: A STUDY IN ENTANGLEMENT AND RESILIENCY A Thesis Submitted to the Committee on Graduate Studies In Partial Fulfillment of the Requirements for the Degree of Master …

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 Full Text: IN THE WILDERNESS AT FÖHRENWALD: J E W I S H R E F U G E E S I N O C C U P I E D U P P E R B AVA R I A , 1945–47 A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfilment of the Requirements for the Degree of Master of Arts in the …

Abstract: <p>In the context of Real-Time Bidding (RTB) the machine learning problems of</p><p>imbalanced classes and model selection are investigated. Synthetic Minority Oversampling Technique (SMOTE) is commonly used to combat imbalanced classes but a shortcoming is identified. Use of a distance threshold is identified as a solution and testing in a live RTB environment shows significant… more Full Text: SMOTE AND PERFORMANCE MEASURES FOR MACHINE LEARNING APPLIED TO REAL-TIME BIDDING A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science …

Abstract: <p>Structure-property relationships are increasingly valued for the identification of specifically engineered materials with properties optimized for targeted application(s). In this work, linear and branched diesters for use in lubricant formulations are prepared from lipid-based oleochemicals and their structure-property relationships reported. It is shown that the branched diesters… more Full Text: NOVEL ALIPHATIC LIPID-BASED DIESTERS FOR USE IN LUBRICANT FORMULATIONS: STRUCTURE PROPERTY INVESTIGATIONS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the …
