Biogas Purification: H2S Removal using Biofiltration
(University of Waterloo, 2010-08-31)Biogas, composed principally of methane, has limited use in energy generation due to the presence of hydrogen sulphide (H2S). Biogas cannot be burned directly in an engine as H2S present causes corrosion in the reaction ... -
Biogeochemical cycling of nutrient silicon in a human-impacted large lake nearshore environment (Hamilton Harbour Area of Concern, Lake Ontario, Canada)
(University of Waterloo, 2017-12-14)The biogeochemical cycling of nutrient silicon (Si) through rivers, wetlands, lakes, and artificial reservoirs regulates the magnitude and bioavailability of Si delivered downstream and to the ocean (Frings et al. 2014; ... -
Biogeochemical Hotspots: Role of Small Water Bodies in Landscape Nutrient Processing
(University of Waterloo, 2017-05-09)Increased loading of nitrogen and phosphorus from agricultural and urban intensification has led to severe degradation of inland and coastal waters. Lakes, reservoirs, wetlands, and streams retain and transform these ... -
Biogeochemical Signatures of the Great Lakes Watersheds
(University of Waterloo, 2018-08-21)Water quality in many regions of the Great Lakes Basin (GLB) has deteriorated due to numerous anthropogenic drivers, including increases in agricultural area, increased fertilizer use, intensive livestock production, and ... -
Biogeochemistry Across Spatiotemporal Scales: The Role of Reactive Interfaces in Modulating Landscape Scale Contaminant Fluxes
(University of Waterloo, 2022-09-09)The intensification of agricultural and urban activities has been accompanied by increased fluxes of nutrients to inland and coastal waters, leading to concerns of eutrophication and drinking water contamination. Certain ... -
Bioinformatic insights into the diversity and evolution of bacterial toxins
(University of Waterloo, 2020-01-24)Bacterial toxins are a broad category of molecules ranging from small organic compounds and peptides to large multi-domain or multi-meric enzymes. Several important diseases are caused primarily by bacterial toxins including ... -
Bioinformatic Insights into the Impacts of External Stimuli on the Human Airway
(University of Waterloo, 2021-12-21)The airway epithelium represents a critical component of the human lung that helps orchestrate defences against inhaled substances including air pollution, allergens, bacteria, and viruses. To manage these continuous ... -
Biointerface Topography for Enhanced Nonviral Gene Delivery
(University of Waterloo, 2023-12-11)Substrate-mediated nonviral gene delivery (SMD) represents a burgeoning area of interest in the field of tissue engineering due to its potential to facilitate localized transfection while providing the scaffolding for ... -
Biological Control of Disease Vectors: A Case Study Evaluating the Efficacy of Fathead Minnows (Pimephales promelas) for Mosquito Control in Northeast Wyoming
(University of Waterloo, 2016-01-12)West Nile virus (WNv) has become a significant and increasing threat to wildlife populations and human health throughout North America. Mosquito control is an important and potentially effective means of controlling the ... -
Biological Plausibility in Modern Hopfield Networks
(University of Waterloo, 2022-12-19)Modern Hopfield Networks (HNs) have the ability to store a large number of target memories (e.g. binary patterns) and then recall a memory in its entirety when prompted by a sub-set or perturbed version of it; in this ... -
Biological responses in rainbow darter (Etheostoma caeruleum) to changes in municipal wastewater quality in the Grand River
(University of Waterloo, 2017-09-27)This thesis is a synthesis of studies that explore the effects of urbanization on a small-bodied fish species, rainbow darter (Etheostoma caeruleum), in the central Grand River (Ontario, Canada) over time. This watershed ... -
Biologically Active Filtration Media Properties: Practical and Mechanistic Implications
(University of Waterloo, 2017-01-16)Biologically active filtration [BAF] can be used to concurrently remove particles and natural organic matter during drinking water treatment. The selection of a given media type for use in BAF can impact filter performance, ... -
