Comparative analysis and visualization of microbial gene neighborhoods: applications to pathogen genomics
(University of Waterloo, 2023-12-20)Gene neighborhoods are clusters of genes that are encoded together within the same genomic region, and may share similarity in expression and/or function. Bioinformatic analysis of gene neighborhoods is a powerful approach ... -
Medication Review in Cognitive Impairment and Dementia: Comparison of Instruments
(University of Waterloo, 2023-12-19)Background: - Cognitive impairment (CI) and dementia are significant concerns in older adults in Canada. Drug-related problems (DRPs) are common and can cause up to 30% of hospitalizations in older individuals, including ... -
EVOLUTION OF MULTI-ARC ACCRETION SYSTEMS: A CASE STUDY FROM THE SOUTHERN BEISHAN OROGEN, CENTRAL ASIAN OROGENIC BELT, NW CHINA
(University of Waterloo, 2023-12-18)The Central Asian Orogenic Belt (CAOB) is characterized as an accretionary orogen, evolved for ca. 800 m.y from late Mesoproterozoic to early Mesozoic. Its terminal collision and accretion generally commenced in the west ... -
Facilitating the Formation of Intermetallic Compounds in Al-Si Coatings on Steel during Hot Stamping
(University of Waterloo, 2023-12-14)Hot-stamped ultrahigh strength steel (UHSS) components are pivotal to automotive light-weighting. Steel blanks, often coated with an aluminum-silicon (Al-Si) layer to protect them from oxidation and decarburization, are ... -
Application of Environmental Metabolomics for Assessment of Aquatic Invertebrate Sensitivity to Naphthenic Acids
(University of Waterloo, 2023-12-14)Naphthenic acids (NAs) are a class of chemicals found in oil sands process waters (OSPW) from the extraction of bitumen from surface mined oil sand. In Alberta, Canada, OSPW is currently stored indefinitely in tailing ponds ... -
Hydride Generation as a Sample Introduction Technique for Detection of Arsenic by Microplasma
(University of Waterloo, 2023-12-08)Microplasma can be used as a portable analytical instrument for elemental analysis of samples due to their small size, low power consumption, low carrier gas consumption, and low cost. This is specifically important for ... -
Investigation of Crystal Structures and Ultra-Low Thermal Conductivities in Novel Group 14 and 15 Chalcogenides
(University of Waterloo, 2023-12-04)The crystal structures and physical properties of several new group 14 and 15 chalcogenides are discussed in this thesis. The thesis discusses the chalcoantimonates TlLa2Sb3Se9 and La12+zSb9-ySe38-z (simplified as La12Sb9Se38). ... -
The Role of Melatonin in Amyloid Interactions with the Model Neuronal Membranes
(University of Waterloo, 2023-11-29)The amyloid cascade hypothesis has long directed research efforts in understanding the pathogenesis of Alzheimer’s disease (AD), ever since it was first proposed through clinical evidence by Hardy and Higgins in 1992. ... -
Neutron Scattering Investigations of Three-Dimensional Topological States
(University of Waterloo, 2023-11-13)Topological magnets represent a unique class of quantum materials in which a nontrivial Berry curvature in real- or momentum-space couples to the magnetic properties of the topological electronic or spin system. Magnetic ... -
Algal priming mediates the effects of light and nutrients on organic matter processing: insights from artificial and natural streams
(University of Waterloo, 2023-10-31)Environmental factors such as light and nutrients may play important roles in determining detrital decomposition through their effects on primary production. Thus, human activities that alter the availabilities of light ... -
The Role of Transverse Faults in Late Gold Mineralization: A Structural Study of the Maskinonge Lake Fault, Michipicoten Greenstone Belt, Ontario
(University of Waterloo, 2023-10-25)The Maskinonge Lake fault is a late NW-striking fault that occurs at a high angle to the structural features of the gold-producing Goudreau Lake Deformation Zone (GLDZ) in the Michipicoten greenstone belt. The fault is ... -
