Aspects of Polymer Chain Dynamics in Solution Studied by Fluorescence
(University of Waterloo, 2008-04-14)Several pyrene-labeled polymers and polypeptides were synthesized and their chain dynamics were characterized using steady-state and time-resolved fluorescence techniques. Firstly, four series of pyrene-labeled polystyrenes ... -
Aspects of Quantum Field Theory with Boundary Conditions
(University of Waterloo, 2019-08-02)This thesis has two modest goals. The primary goal is to deliver three results involving particle detectors interacting with a quantum field in presence of non-trivial boundary conditions (Dirichlet, Neumann, periodic; ... -
Aspects of Quantum Information and AdS/CFT Duality
(University of Waterloo, 2021-05-17)This thesis considers four different aspects of quantum information, AdS/CFT duality, and the interplay between them. First, we study the holographic complexity conjectures in detail for rotating black holes. We focus ... -
Aspects of Scattering Amplitudes and Moduli Space Localization
(University of Waterloo, 2019-08-19)We propose that intersection numbers of certain cohomology classes on the moduli space of genus-zero Riemann surfaces with $n$ punctures, $\mathcal{M}_{0,n}$, compute tree-level scattering amplitudes in quantum field ... -
Assembly of DNA-Functionalized Gold Nanoparticles with Gaps and Overhangs in Linker DNA
(American Chemical Society, 2011-04-28)DNA-directed assembly of gold nanoparticles (AuNPs) has been extensively studied because of its important applications in analytical chemistry, materials science, and nanomedicine. In a typical system, two DNA-functionalized ... -
Assembly of DNA-Functionalized Nanoparticles in Alcoholic Solvents Reveals Opposite Thermodynamic and Kinetic Trends for DNA Hybridization
(American Chemical Society, 2010-05-12)DNA has been a key molecule in biotechnology and nanotechnology. To date, the majority of the experiments involving DNA have been performed in aqueous solutions, which may be related to the perception that DNA hybridization ... -
Assessing hydrological processes controlling the water balance of lakes in the Peace-Athabasca Delta, Alberta, Canada using water isotope tracers
(University of Waterloo, 2007-05-22)One of the world’s largest freshwater deltas (~4000 km2), the Peace-Athabasca Delta (PAD), is located at the convergence of the Peace and Athabasca rivers and Lake Athabasca in northern Alberta, Canada. Since the early ... -
Assessing Medication Adherence in Older Adults with Memory Concerns in a Primary Care-Based Memory Clinic
(University of Waterloo, 2015-10-02)There is an increasing prevalence of cognitive impairment in the rapidly ageing population. Cognitive impairment has been shown to be a unique barrier to medication adherence in older adults coupled with an increased number ... -
Assessing Microbial Viability and Biodegradation Capabilities in Sandstone
(University of Waterloo, 2017-11-17)Environmental practitioners have demonstrated enhanced in situ bioremediation (EISB) in homogeneous unconsolidated soils to remediate chlorinated solvents. However, EISB has not been fully investigated in bedrock environments. ... -
Assessing Physicochemical Properties of Drug Molecules via Microsolvation Measurements with Differential Mobility Spectrometry
(American Chemical Society, 2017-02-22)The microsolvated state of a molecule, represented by its interactions with only a small number of solvent molecules, can play a key role in determining the observable bulk properties of the molecule. This is especially ... -
Assessing reasons for changes in the condition of Deception Bay Arctic charr (Salvelinus alpinus)
(University of Waterloo, 2019-01-24)The Raglan Mine sport fishing program has collected biological fish data in Deception Bay, Nunavik, Québec, Canada since 1998 in collaboration with local committees, small scale sampling programs, and government agencies ... -
Assessing relations among multiple environmental gradients for shallow lakes in Old Crow Flats, Yukon, using hydrological, limnological and community-collaborative research approaches
(University of Waterloo, 2018-01-09)Shallow freshwater ecosystems are undergoing marked hydrological changes associated with a warming Arctic, which causes concern for remote northern communities that access these regions to maintain their traditional ... -
Assessing Sensitivity of Subsurface Mine-Dewatering Activities to Climate Change
(University of Waterloo, 2023-09-01)Underground mining activities require constant removal of groundwater from their void spaces to maintain dry and safely accessible excavations for ore extraction in a process known as dewatering. The nature and degree ... -
Assessing Stratigraphic Controls on the Secondary Detrital Footprint from Buried Mineralization and Alteration at the Highland Valley Copper Mine, British Columbia
(University of Waterloo, 2020-01-24)Mineral exploration is progressively shifting to deeper targets, including those buried under thick unconsolidated sediments. It is thus becoming increasingly important to understand the sedimentary successions of the ... -
Assessing Taxonomic Issues with the Genera Anabaena, Aphanizomenon and Nostoc Using Morphology, 16S rRNA and efp genes
(University of Waterloo, 2009-01-08)Cyanobacteria are an ancient lineage of gram-negative photosynthetic prokaryotes that play an important role in the nitrogen cycle in terrestrial and aquatic systems. Widespread cyanobacterial blooms have prompted numerous ... -
Assessing the Accuracy of Cosmological Parameters Estimated from Velocity – Density Comparisons
(University of Waterloo, 2024-01-10)A promising method for measuring the cosmological parameter combination fσ₈ is to compare observed peculiar velocities with peculiar velocities predicted from a galaxy density field using linear perturbation theory, known ... -
Assessing the biodegradability of dissolved organic carbon in freshwater systems
(University of Waterloo, 2024-06-18)Dissolved organic carbon (DOC) is an important contributor to both carbon (C) cycling and other biogeochemical processes in aquatic ecosystems as it is the most mobile fraction of organic matter. The biodegradable fraction ... -
