Detection of Nitroaromatics Using the Excimer Fluorescence of Pyrene-Labeled Starch Nanoparticles
(American Chemical Society, 2019-09-09)Starch nanoparticles (SNPs) were hydrophobically modified using 1-pyrenebutyric acid (PyBA) with degrees of substitution (DS) between 0.0006 and 0.11. Fluorescence quenching studies were conducted on the pyrene-labeled ... -
Detectors, Reference Frames, and Time
(University of Waterloo, 2017-11-08)This thesis is divided into three parts. Part I investigates the behaviour of Unruh-DeWitt detectors on curved spacetimes admitting a Wightman function and the associated measurement model is identified. These detectors ... -
Determination of Geosmin and 2-Methylisoborneol in Fish using In-vivo Solid Phase Microextraction
(University of Waterloo, 2012-08-31)The presence of off-flavor compounds in fish represents one of the significant economic problems encountered in aquaculture. These off-flavor compounds are due to the absorption of substances produced by microorganisms. ... -
Determination of Polycyclic Aromatic Hydrocarbons in Sediment by Pressure-Balanced Cold Fiber Solid Phase Microextraction
(American Chemical Society, 2017-09-20)An improved performance of the cold fiber solid phase micro extraction (CF-SPME) technique was accomplished with the use of the pressure balanced procedure. In order to obtain a pressure-balanced state during extraction ... -
Determination of the relationship between vancomycin trough concentrations and the AUC/MIC Dosing
(University of Waterloo, 2020-07-15)Rationale: The recently revised guidelines for the therapeutic monitoring of vancomycin recommend targeting an AUC/MIC of 400-600 for serious methicillin-resistant Staphylococcus aureus (MRSA) infections. The feasibility ... -
Determining Analytical Potential Energy Functions of Diatomic Molecules by Direct Fitting
(University of Waterloo, 2001)The fully quantum mechanical 'direct-potential-fit' (DPF) method has become increasingly widely used in the reduction of diatomic spectra. The central problem of this method is the representation of the potential energy ... -
Determining food web impacts on experimental aquatic systems from the disposal of oil sands process-affected waste materials.
(University of Waterloo, 2006)Current mining operators in the Athabasca oil sands deposit of Alberta, Canada have made commitments to zero discharge of oil sands process-affected waste materials (OSPM) from the mine site and rehabilitation of mined ... -
Determining Molecular Physicochemical Properties Using Differential Mobility Spectrometry
(University of Waterloo, 2019-09-26)This thesis aims to explore the usage of differential mobility spectrometry (DMS) and quantum chemical calculations to separate and identify drug compounds, as well as the use of machine learning (ML) to predict physicochemical ... -
Determining the habitat occupancy of young of year Arctic Grayling (Thymallus arcticus) in sub-Arctic tundra streams while accounting for imperfect detection
(University of Waterloo, 2016-01-22)I developed multi-state, multi season occupancy models to determine how a number of interacting ecological variables influence the occurrence of young-of-year (YOY) Arctic Grayling (Thymallus arcticus) in nine streams on ... -
Determining the native and nonnative effects of myristoylation on the folding and switching of hisactophilin
(University of Waterloo, 2012-09-26)Myristoylation, the covalent linkage of a C14 saturated fatty acyl chain to the N-terminal glycine in a protein, plays an important role in reversible membrane and protein binding in cellular signaling by the modified ... -
