Ecosystem oxygen metabolism in an impacted temperate river network: Application of the δ18O-DO approach
(University of Waterloo, 2013-04-22)Ecosystem metabolism is an important indicator of aquatic ecosystem function. This thesis concerns ecosystem metabolism as recorded by daily variation in dissolved oxygen (DO) and δ18O-DO in an impacted temperate river ... -
Ecosystem Services: Linking ecohydrology with economic valuation
(University of Waterloo, 2018-10-17)Economic valuation of ecosystem services has become a dominant model for environmental management at local, regional and global scales. However, policy-makers at all scales take these value estimates with a pinch of salt. ... -
Edge Modes and Carrollian Hydrodynamics on Stretched Horizons
(University of Waterloo, 2022-09-27)The first part of this thesis is aimed at investigating the crucial role played by emergent boundary degrees of freedom, called edge modes, in gauge theories defined in spacetimes with boundaries. We propose a simple and ... -
Effect of a Mobile Phone Intervention on Quitting Smoking in a Young Adult Population of Smokers: Randomized Controlled Trial
(JMIR, 2018-10-23)Background: Digital mobile technology presents a promising medium for reaching young adults with smoking cessation interventions because they are the heaviest users of this technology. Objective: The aim of this study ... -
The effect of a protein-restricted diet during pregnancy on the expression of the amino acid transporter System B0,+ in early rat embryos
(University of Waterloo, 2010-01-04)Epidemiological studies have shown that human adults have a higher chance of developing various metabolic disorders, such as type II diabetes and hypertension, due to maternal under nutrition. The concept that conditions ... -
The Effect of a Source Change for an Active Pharmaceutical Ingredient (API) or Excipient on the Finished Drug Product
(University of Waterloo, 2016-08-10)The global cost of health care is increasing year after year, and one of the ways governments and health care providers are looking to reduce cost is by reducing the cost of drug products. The generic industry is under ... -
Effect of aging on measures of visual attention using dual tasks and visual search
(University of Waterloo, 2010-01-19)In Canada, as baby boomers age, there will be an increase in the percentage of seniors within the general population (Statistics Canada, 2006). Seniors often have difficulty in performing certain everyday tasks and have ... -
Effect of ambient humidity on the Cochet-Bonnet aesthesiometer
(Springer Nature, 2018-06-19)Purpose: The Cochet–Bonnet (COBO) aesthesiometer is the current standard in corneal sensitivity assessment. This study investigates the influence of ambient room humidity levels on the stimulus force exerted by the ... -
Effect of Background Water Matrices on Pharmaceutical and Personal Care Product Removal by UV-LED/TiO2
(Multidisciplinary Digital Publishing Institute, 2021-04-30)In this study, we evaluated the effectiveness of UV-LED-irradiated TiO2 in removing 24 commonly detected PPCPs in two water matrices (municipal wastewater effluent and Suwannee River NOM–synthetic water) and compared their ... -
Effect of chain stiffness on the entropic segregation of chain ends to the surface of a polymer melt
(2019)Entropic segregation of chain ends to the surface of a monodisperse polymer melt and its effect on surface tension is examined using self-consistent field theory (SCFT). In order to assess the dependence on chain stiffness, ... -
Effect of combined sodium arsenite and cadmium chloride treatment on heat shock protein gene expression in Xenopus laevis A6 kidney epithelial cells
(University of Waterloo, 2013-09-26)Sodium arsenite and cadmium chloride are two widespread environmental toxicants which have deleterious effects on living organisms. At the cellular level, sodium arsenite and cadmium chloride cause oxidative stress, ... -
Effect of composting and amendment with biochar and woodchips on the fate and leachability of pharmaceuticals in biosolids destined for land application
(Elsevier, 2022-03)Land application of biosolids can improve soil fertility and enhance crop production. However, the occurrence and persistence of pharmaceutical compounds in the biosolids may result in leaching of these contaminants to ... -
Effect of Dissipation on the Dynamics of Superconducting Single Electron Transistors
(University of Waterloo, 2012-08-30)In this thesis, I will present the experimental results of the dynamics of superconducting single electron transistors (sSETs), under the influence of tunable dissipation. The sSET, consisting of two dc SQUIDs in series ... -
Effect of ethanol on BTEX biodegradation in aerobic aquifer systems
(University of Waterloo, 2008-01-04)Ethanol can affect the biodegradation of gasoline hydrocarbons in groundwater. High concentrations of ethanol can be toxic to subsurface microorganisms that are otherwise capable of degrading hydrocarbons, such as benzene, ... -
Effect of Fuel Ethanol on Subsurface Microorganisms and its Influence on Biodegradation of BTEX Compounds.
(University of Waterloo, 2000)Ethanol is used as fuel in neat form in some countries (Brazil and India) or blended with gasoline (Europe, Canada and the United States). The benefits of ethanol use include octane enhancement, a cleaner environment and ... -
Effect of Gemini Surfactants on Amyloid Beta Aggregation
(University of Waterloo, 2013-09-27)Alzheimer’s disease (AD) is a progressive dementia affecting cognition, behavior, and functional status and there is no cure which exists for it. In AD, Amyloid Beta (Aβ) peptides form aggregates that are neurotoxic in the ... -
