The Statistical Derivation of Environmental Quality Guidelines
(University of Waterloo, 2015-04-30)The thesis investigated statistical tools to improve the derivation of direct and indirect environmental quality guidelines (EQGs). Direct EQGs use measurements taken directly from the environmental matrix or phase of ... -
The Statistical Fingerprints of Quantum Gravity
(University of Waterloo, 2008-09-29)In this thesis some equilibrium and non-equilibrium statistical methods are implied on two different versions of non-perturbative quantum gravity. Firstly, we report a novel statistical mechanics in which a class ... -
Statistical Muon Tracking: A Study of Cosmic Backgrounds in the PROSPECT Experiment
(University of Waterloo, 2021-09-30)The Precision Reactor Oscillation and Spectrum Experiment (PROSPECT) has successfully demonstrated novel particle identification strategies with minimal protection from cosmic events. Located at the High Flux Isotope Reactor ... -
Stereocoherence thresholds as a measure of global stereopsis
(University of Waterloo, 2017-06-14)Purpose: The purpose of this study was to develop a robust and reliable clinical test of stereopsis that is complementary to the conventional disparity threshold tests. Methods: Random dot stereograms containing ... -
Stille Coupling of α-Acyloxybenzylstannanes with Acid Chlorides
(University of Waterloo, 2016-08-19)Two widely-accepted models (open- and cyclic- transmetalation) are applied to explain the stereochemical outcome of the Stille coupling with organotin compounds containing an sp3 chiral center. However, it is still not ... -
Stille Coupling of α-Alkoxybenzylstannanes: Optimization Study and Stereochemical Outcome
(University of Waterloo, 2011-08-24)In order to make the stereospecific palladium-catalyzed cross-coupling of α-alkoxybenzyl-stannanes a useful synthetic methodology, optimization was undertaken to improve the coupling yields between these stannanes and ... -
Stille Coupling Reactions Involving α-Alkoxybenzylstannanes
(University of Waterloo, 2007-12-20)The Stille reaction has established itself as one of the two most general and most selective palladium-catalyzed cross-coupling reactions, along with the Suzuki cross-coupling of organoboron compounds. The Stille coupling ... -
Stimulating In Situ Denitrification in an Aerobic, Highly Conductive Municipal Drinking Water Aquifer
(University of Waterloo, 2010-04-14)Best or beneficial management practices (BMPs) are often relied upon as a mitigation strategy for nitrate contamination throughout Canada. At a regional scale, reducing the quantity of nutrients applied to agricultural ... -
Stimuli-responsive releasing of gold nanoparticles and liposomes from aptamer-functionalized hydrogels
(Institute of Physics, 2011-11-21)Controlled release of therapeutic agents is important for improving drug efficacy and reducing toxicity. Recently, hydrogels have been used for controlled release applications. While the majority of the previous work focused ... -
Stimulus characteristics of a novel air-based multiple stimulus aesthesiometer
(University of Waterloo, 2022-01-05)Purpose: To (1) develop a novel air-based aesthesiometer capable of producing and applying multiple stimuli separated either by time or space; (2) identify the stimulus airflow characteristics and confirm the consistency ... -
Strategies for the Direct Coupling of Solid Phase Microextraction to Mass Spectrometry
(University of Waterloo, 2017-09-27)In recent years, advances in direct sample to mass spectrometry (MS) techniques have allowed for the application of these methods towards quantitative analysis in complex matrices such as biofluids and tissue. However, the ... -
Strategies to Improve Solid Phase Microextraction Sensitivity: Temperature, Geometry and Sorbent Effects
(University of Waterloo, 2013-04-24)Solid phase microextraction (SPME) has been widely used in a variety of sample matrices and proven to be a simple, fast and solvent-free sample preparation technique. A challenging limitation in the further development of ... -
Strategies Towards Asymmetric Conjugate Trifluoromethylation of α,β-Unsaturated Ketones and the Asymmetric Conjugate Addition of Boronates to β-Trifluoromethyl α,β-Unsaturated Ketones
(University of Waterloo, 2014-09-02)Currently, there are no reported methods in the literature for the conjugate addition of the trifluoromethyl group to α,β-unsaturated ketones. A bulk of this thesis focused on developing a method to overcome this problem. ... -
Stratigraphy, Structure and Geochronology of Archean Lode Gold Deposits in the Southeastern Rice Lake Greenstone Belt, Southeast Manitoba
(University of Waterloo, 2017-01-24)The Central Manitoba mine trend is one of the most important lode gold camps in the Rice Lake greenstone-granitoid belt of the western Uchi Subprovince within the western Superior Province, Manitoba, Canada. Neoarchean ... -
Streptococcus agalactiae CAMP factor: Functional Roles of N- and C-terminal Domains & Target Membrane Effect on Toxin Activity
(University of Waterloo, 2018-05-22)CAMP factor is a well-known pore-forming toxin secreted by Streptococcus agalactiae that forms discrete pores on susceptible membranes whether natural or artificial. This work reports haemolysis and liposome permeabilization ... -
Stress and metabolic responses to municipal wastewater effluent exposure in rainbow trout effluent
(University of Waterloo, 2011-08-30)Municipal wastewater effluent (MWWE) is an important source of pollution in the aquatic environment impacting fish. MWWE is a complex mixture of chemicals including pharmaceuticals, personal care products, industrial ... -
Stress Physiology of Bears: Cortisol Dynamics and Identification of Novel Serum Proteins
