The Investigation of Tear Film Osmolality as a Clinical Instrument Used in Assessments of the Tear Film and Dry Eye Disease
(University of Waterloo, 2010-01-11)Introduction: Tear film osmolality is a product of the varying concentrations of dissolved solutes (proteins, lipids and mucins) in the tear fluid. Research suggests that a hyperosmotic tear film is a trait common to ... -
An Investigation of the Abundance and Key Habitat Parameters of the Northern Map Turtle (Graptemys geographica) in an Eastern Ontario Bay - A Baseline Study
(University of Waterloo, 2007-05-16)This study assessed the principles of ecosystem management and utilized the Northern Map turtle, a species at risk, as a key indicator species to illustrate the importance of preserving riparian habitats and island complexes ... -
An investigation of the biomechanical factors influencing knee joint function following total knee replacement
(University of Waterloo, 2009-12-22)Knee replacement surgery is often performed in cases where the pain due to knee osteoarthritis can no longer be effectively controlled by conservative measures. The surgery—which replaces the articular surfaces of the ... -
Investigation of the effect mutations of CaM have upon in vitro and ex vivo function
(University of Waterloo, 2010-01-22)Calmodulin (CaM) is a calcium-binding protein that has promiscuous regulatory interactions with over three hundred intracellular protein targets. The focus of this study was to characterize the functional role of phosphorylated ... -
Investigation of the Effects of Coagulation on Membrane Filtration of Moving Bed Biofilm Reactor Effluent
(University of Waterloo, 2010-05-19)The combination of moving bed biofilm reactors and membrane bioreactors (MBBR-MR) can compensate for the drawbacks of both of these systems and further increase their acceptance and application in wastewater treatment ... -
Investigation of the Efficacy of in situ Degradation Methods for Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonic Acid (PFOS) in Groundwater
(University of Waterloo, 2018-01-17)Per- and polyfluoroalkyl substances (PFASs) are a group of emerging contaminants that include perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). PFASs can be released into groundwater through the ... -
Investigation of the Electronic Structure and Magnetic Properties of CeO2-X
(University of Waterloo, 2023-09-19)In literature, it has been reported that undoped CeO2 exhibits a room-temperature ferromagnetic-like ordering that does not follow Curie-type behaviour, typically found in magnetic materials. However, none of the proposed ... -
Investigation of the Impact of Mixing Intensity on Dissolved Oxygen Half Velocity Constants in a Sidestream Deammonification Environment
(University of Waterloo, 2017-12-18)The liquid waste (centrate) from the dewatering stage in the solids treatment stream (sidestream) of a wastewater treatment plant is typically rich in ammonium. If this centrate is recycled to the wastewater treatment ... -
Investigation of the Impacts of Thermal Activated Sludge Pretreatment and Development of a Pretreatment Model
(University of Waterloo, 2012-12-03)Waste activated sludge (WAS) pretreatment technologies are typically evaluated in terms of the associated improvement in biogas and sludge production during digestion and post-digestion dewaterability. However, WAS ... -
Investigation of the Interaction of Particulate Matter with the Gas Diffusion Layer
(University of Waterloo, 2017-06-14)Rapid global industrialization has resulted in an unprecedented level of energy consumption. Transportation comprises a significant portion of the demand for energy, and special attention has recently been paid to green ... -
