Analysis of peptide production by Lactobacillus species and evaluation of their antihypertensive and immunomodulatory activities
(2015-08-01)Cardiovascular disease (CVD) is the leading cause of death among Canadian adults. Research has demonstrated an inverse relationship between the consumption of fermented dairy products and a decreased risk of CVD due to ... -
Analysis of resistance nodulation division efflux pumps in Acinetobacter baumannii
(2015-01-01)Strains from Canadian hospitals were classified as A. baumannii, A. pitti, or A. osocomialis and the most commonly expressed resistance nodulation division (RND) efflux pump was adeFGH. A collection of A. baumannii isolates ... -
The analysis of the entomological and chemical decomposition of human remains to ultimately assess the viability of the domestic pig as a substitute in forensic applications
(2022-09-01)Death investigations often rely on the minimum post mortem interval (minPMI) estimations provided by forensic entomologists. The models accepted by courts in Canada are not based on research involving humans but rather on ... -
Analysis of the volatile organic compounds produced by the decomposition of pig carcasses and human remains
(2013-03-01)Complex processes of decomposition produce a variety of chemicals as soft tissues and their component parts are degraded. Among others, these decomposition by-products include volatile organic compounds (VOCs) responsible ... -
Anodic alcohol fuel cell reactions at platinum active sites on doped metal oxide supports
(2022-12-01)Fuel cells produce electrical energy via chemical reactions, which take place on the carbon supported platinum catalyst (Pt/C). As attractive as these devices may seem, their practicality is often limited by the functionality ... -
An anomaly detection model utilizing attributes of low powered networks, IEEE 802.15.4e/TSCH and machine learning methods
(2019-12-01)The rapid growth in sensors, low-power integrated circuits, and wireless communication standards has enabled a new generation of applications based on ultra-low powered wireless sensor networks. These are employed in many ... -
The anti-estrogenic and liver metabolic effects of DHAA in rainbow trout (oncorhynchus mykiss)
(2011-08-01)Recent studies have shown that dehydroabietic acid (DHAA), a resin acid present in pulp and paper mills, may have anti-estrogenic effects in fish. A chronic-exposure toxicity experiment using immature rainbow trout (Oncorhynchus ... -
Applications and numerical investigation of differential-algebraic equations
(2010-05-01)Differential-algebraic equations (DAEs) result in many areas of science and engineer- ing. In this thesis, numerical methods for solving DAEs are compared for two prob- lems, energy-economic models and traffic flow models. ... -
Approaching Humanities Questions Using Slow Visual Search Interfaces
(2021-06-01)In this paper we discuss a visual search system that was designed and implemented for humanities scholars to ask questions of large document corpora. The system allows searches to be specified through traditional search, ... -
Arthropod successionin Whitehorse, Yukon Territory and compared development of protophormia terraenovae (R. -D.) from Beringia and the Great Lakes Region
(2012-07-01)Forensic medicocriminal entomology is used in the estimation of post-mortem intervals in death investigations, by means of arthropod succession patterns and the development rates of individual insect species. The purpose ... -
Assessing nearshore water quality and biological condition in the Kawartha Lakes using a community science approach
(2022-08-01)The Kawartha Lakes, located in south-central Ontario, are a popular tourist destination, with a growing permanent resident population. Consequently, land development in its watersheds continues, and the specific land-use ... -
Assessing the influence of geological and land-use gradients on zooplankton and phytoplankton biodiversity in the land between ecotone
(2021-11-01)The Land Between (TLB) is an ecotone in south-central Ontario that represents a transition from limestone-dominated bedrock to granite-dominated bedrock, creating notable calcium and land-use gradients across this unique ... -
Assessing the memorability of familiar vocabulary for system assigned passphrases
(2021-08-01)Text-based secrets are still the most commonly used authentication mechanism in information systems. Initially introduced as more secure authentication keys that people could recall, passphrases are tokens consisting of ... -
Assessing the use of DNA expert evidence, by justice system participants, in Ontario criminal courts
(2017-08-01)What happens to forensic DNA opinion evidence when the expert witness is not present in the courtroom? Research addressing this issue has largely been focused on polling lawyers regarding their perceptions of DNA evidence, ... -
Assessment of wastewater algae for use in biofuel production
(2013-08-01)Although new technologies have allowed the attainment of previously untapped fossil fuels these practises are unsustainable and harmful to the environment. Part of the solution to ease the fuel burden is through renewable ... -
Augmenting free-form annotations with digital metadata for close reading of poetry
(2015-12-01)Many people, literary critics in particular, practice close reading, making annotations by hand while performing a detailed analysis of a text. Current digital tools for literary criticism,however, have many limitations ... -
Autism Serious Game Framework (ASGF) for Developing Games for Children with Autism
(2019-12-01)Autism spectrum disorder (ASD) is characterized by impaired social communication and interaction, and by restricted, repetitive interests and behaviours. The mean clinical age of diagnosis is still four to five years, ... -
