Amelioration of Plant Drought Stress by Plant Growth-Promoting Bacteria
(University of Waterloo, 2017-04-28)Plant growth-promoting bacteria (PGPB) that contain the enzyme (1-aminocyclopropane-1-carboxylate) ACC deaminase protect a variety of plants against damage from various biotic and abiotic stresses. Here, the ability of ... -
Amended Model of Large Scale Dark Matter Structure
(University of Waterloo, 2020-09-03)Dark matter makes up around a quarter of the total energy density in the universe, but its identity remains elusive. Current ways of studying dark matter have centered around its macroscopic properties, such as density ... -
Ammonia-oxidizing archaea and complete ammonia-oxidizing bacteria in a municipal wastewater treatment plant
(University of Waterloo, 2018-09-25)High levels of ammonia in aquatic environments can lead to eutrophication, oxygen depletion, and toxicity to aquatic animals. An important goal of municipal wastewater treatment plants (WWTPs) is to remove ammonia from ... -
Ammonium Attenuation and Nitrogen Dynamics in Groundwater Impacted By a Poultry Manure Lagoon
(University of Waterloo, 2011-06-21)Fertilizer application and manure use practice in agriculture has become one of the most common sources of dissolved nitrogen species to both ground and surface waters. Nitrogen, released as nitrate (NO3-), ammonium (NH4+) ... -
Analysis of Cyanobacteria and its Abundance in the Turkey Lakes Watershed using Molecular Techniques
(University of Waterloo, 2023-12-21)Toxic cyanobacterial blooms continue to pose a threat to the quality and safety of drinking water globally by producing toxins and forming dense surface blooms. Forested watersheds naturally provide high quality drinking ... -
An Analysis of Glacial Sediment Dispersion with Applications to Diamond Exploration, Lac de Gras, Northwest Territories
(University of Waterloo, 2020-09-21)Diamond exploration is important to the economy of the Northwest Territories and Canada. In recent years, however, there has been a marked decline in the discovery rate of large diamond deposits. Emphasis is being put on ... -
Analysis of heat shock-, sodium arsenite- and proteasome inhibitor-induced heat shock protein gene expression in Xenopus laevis
(University of Waterloo, 2009-05-01)Previous studies have focused on the effect of individual stressors on hsp gene expression in eukaryotic organisms. In the present study, I examined the effect of concurrent low doses of sodium arsenite and mild heat shock ... -
Analysis of Immune System and Stress Parameters of Oncorhynchus mykiss in Response to Juvenile Thermal Preconditioning or Thermal-Based Parental Selection
(University of Waterloo, 2021-09-20)Higher water temperatures and pathogens are both significant factors that negatively affect the welfare of teleost fish. In aquaculture, compared to natural populations, these problems are especially exacerbated, as the ... -
Analysis of premature loss of the extraembryonic Amnioserosa in Drosophila morphogenetic mutants
(University of Waterloo, 2009-01-23)During Drosophila embryogenesis, an extra-embryonic tissue, known as the amnioserosa (AS), is required for the morphogenetic processes of germ band retraction (GBR) and dorsal closure (DC). Being extra-embryonic, the AS ... -
Analysis of Programmed Cell Death in the Amnioserosa, an Extra-embryonic Epithelium in Drosophila melanogaster
(University of Waterloo, 2008-01-24)The amnioserosa (AS) is an epithelium that plays major roles in two crucial morphogenetic processes during Drosophila embryogenesis: Germ Band Retraction (GBR) and Dorsal Closure (DC). The AS is extraembryonic and as such, ... -
Analysis of Temporal Changes in Estrogenic Compounds Released from Municipal Wastewater Treatment Plants
(University of Waterloo, 2019-09-26)Wastewater treatment plants (WWTPs) are traditionally designed to target the removal of contaminants such as total suspended solids, phosphorous, biological oxygen demand, and ammonia. Recent changes to the Federal ... -
Analysis of the Behaviour of Long-Runout Rock Avalanches Using Simple Energy Models
(University of Waterloo, 2021-05-06)Rock avalanches are a natural hazard of fragmented rock with extreme geomorphological impact and cause significant amounts of damage to the human population. This thesis develops and evaluates simple physics-based energy ... -
Analysis of the structural determinants for voltage-dependent G protein modulation of synaptic Cav2 channels
(University of Waterloo, 2008-08-28)Specialized voltage-gated calcium channels in the Cav2 channel class (such as Cav2.2, N-type) mediate neurotransmitter release from presynaptic nerve terminals. Cav2.2 channels are exquisitely sensitive to inhibition by ... -
Analysis of the Thermal Fisher Information in 2+1 Dimensional Black Hole Spacetimes
(University of Waterloo, 2023-01-24)In the past decade, relativistic quantum information (RQI) has presented itself as a promising avenue for examining the interaction between relativistic and quantum effects. This is most commonly achieved by coupling ... -
Analytical and Numerical Studies of 2D XY Models with Ring Exchange
(University of Waterloo, 2012-08-31)In this thesis we take several different analytic and numerical approaches to studying the classical J-K model. This model describes an interacting many-body system of spins with continuous symmetry which interact via ... -
Analytical Investigation of Gas Production from Methane Hydrates upon Thermal Stimulation
(University of Waterloo, 2020-02-14)In this study, analytical models are developed to investigate methane hydrate dissociation in porous media upon thermal stimulation employing wellbore heating. This work investigates how the wellbore’s external and internal ... -
Antioxidant Defence Response in Non-Target Fishes Following Pharmaceutical Wastewater Effluent Exposure
(University of Waterloo, 2022-05-05)The Grand River watershed extends throughout the majority of Southern Ontario with its final outlet at Lake Erie and accommodates thirty wastewater treatment plants (WWTP) with varying types and degrees of treatment. ... -
Antiviral responses of Xela DS2 and Xela VS2, two newly established Xenopus laevis skin epithelial-like cell lines, to viral dsRNA and Frog Virus 3
(University of Waterloo, 2019-09-27)There is a current decline in amphibian populations, wherein the emerging pathogen Frog Virus 3 (FV3) is believed to be a proximate cause. The conservation of frog species is thus important as population declines would ... -
