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, ... -
Purification and determination of oxidative modifications of the thermostable alcohol dehydrogenase from Thermococcus guaymasensis
(University of Waterloo, 2019-09-13)Hyperthermophiles are microorganisms that grow optimally at 80°C and above. They have been found to be resilient to extremes of pH, redox potential, pressure and salinity. Moreover, they can utilize a wide range of ... -
Toxicity and bioaccumulation kinetics of cadmium and potassium permanganate in two clades within the 𝘏𝘺𝘢𝘭𝘦𝘭𝘭𝘢 𝘢𝘻𝘵𝘦𝘤𝘢 species complex
(University of Waterloo, 2019-09-12)The freshwater amphipod 𝘏𝘺𝘢𝘭𝘦𝘭𝘭𝘢 𝘢𝘻𝘵𝘦𝘤𝘢 has been frequently used in toxicology since the 1980s due to its general sensitivity, ease of culture, and North America-wide geographic range. Over the past 20 years, ... -
Exploring microbial diversity across a Southern Ontario landfill
(University of Waterloo, 2019-09-11)Sanitary landfills are highly engineered environments that receive a heterogeneous mixture of organic waste, metals, and plastics. Global waste production continues to grow every year and waste management is an increasing ... -
Development of Solid Phase Microextraction Methodologies for the Determination of Anthropogenic Contaminants from Fatty Food Matrices
(University of Waterloo, 2019-09-03)Anthropogenic contaminants have been on the rise worldwide due to global industrialization. The world is now faced with the consequences of the pollution caused by the exposure of man-made chemicals in the environment. ... -
Benthic-pelagic coupling and spatial dynamics of nutrient availability for benthic nuisance algae in the rocky nearshore zone of eastern Lake Erie
(University of Waterloo, 2019-09-03)Nuisance Cladophora growth in the nearshore during the summer growing season tends to imply nutrient, particularly phosphorus (P), enrichment in the benthos, especially where there is adequate light and hard substrate that ... -
Tunable three-body interactions between superconducting flux qubits for quantum annealing
(University of Waterloo, 2019-09-03)The field of quantum information has been a fast growing field of research in the last few decades. The reason for this development is the potentially immense power of quantum computers, capable of solving hard problems ... -
Probing universality with entanglement entropy via quantum Monte Carlo
(University of Waterloo, 2019-08-30)Our understanding of physical phenomena hinges on finding universal core mechanisms that unite them. The concept of universality is deeply ingrained in the study of quantum many-body systems. At zero temperature, microscopically ... -
Bioenergetics of mixotrophic metabolisms: A theoretical analysis
(University of Waterloo, 2019-08-29)Many biogeochemical reactions controlling surface water and groundwater quality, as well as greenhouse gas emissions and carbon turnover rates, are catalyzed by microorganisms. Representing the thermodynamic (or bioenergetic) ... -
Effects of Temperature on the Proliferation of Human and Fish Lens Epithelial Cells
(University of Waterloo, 2019-08-29)Crystallins are proteins that confer refractive properties to the crystalline lens. All vertebrate lenses contain α- and β-crystallins, and often a third major crystallin. Crystallins can have additional non-refractive ... -
Optical Resonators Integrated into a Hollow Core Photonic Crystal Fiber for Enhanced Light-Matter Interactions
(University of Waterloo, 2019-08-29)The focus of this thesis is to investigate and fabricate a platform that can facilitate the enhancement of light-matter interactions. By tightly confining the photons and atoms to the same region of space, the probability ... -
Equilibrium Phase Behaviour of Liquid Crystalline Polymer Brushes
(University of Waterloo, 2019-08-29)Using self-consistent field theory of worm-like chains with Maier-Saupe interactions we study the equilibrium phase behaviour of liquid crystalline (LC) polymer brushes. In a good solvent the brush extends out normal to ... -
Dissolved Organic Matter in the Canadian Arctic & Sub-Arctic: Importance of DOM Quality & Quantity in a Warming Climate
(University of Waterloo, 2019-08-28)Dissolved organic matter (DOM) is a ubiquitous component of aquatic and terrestrial systems and an important constituent that can influence aquatic health and drinking water quality. For instance, DOM can act as an important ... -
Hydrophobic Modification of Starch
(University of Waterloo, 2019-08-27)Starch is a very common polysaccharide with multiple applications in the industry, but the range of physical properties exhibited by that material is relatively limited due to its strongly hydrophilic character. The work ... -
Estimation of Heading direction Using Optic Flow
(University of Waterloo, 2019-08-26)Background The purpose of this study was to investigate the effect of the reduction of the uniocular light luminance as well as the effect of unequal retinal image sizes by using uniocular size lenses, on the heading ... -
Machine Learning Topological Defects of Liquid Crystals in Two Dimensions
(University of Waterloo, 2019-08-26)Over the recent few years, condensed matter physics has keenly been testing out the compelling techniques from the toolbox of machine learning. Order parameters, phase transitions, and other thermodynamic quantities have ... -
MicroRNAs and their role within the teleost (Oncorhynchus mykiss) stress response
(University of Waterloo, 2019-08-26)The stress response is a highly conserved signalling cascade that signals between tissues to increase energy availability. Changes in glucose regulation are studied extensively due to the glucose intolerant phenotype of ... -
