1-AMINOCYCLOPROPANE-1-CARBOXYLATE (ACC) DEAMINASE GENES IN RHIZOBIA: ISOLATION AND CHARACTERIZATION
(University of Waterloo, 2007-05-14)A collection of 233 putative Rhizobia strains from 30 different sites across Saskatchewan, Canada was assayed for ACC deaminase activity, with 27 of the strains displaying activity. When all 27 strains were characterized ... -
1H MAS NMR Study of Water on Pd-MCM-41
(University of Waterloo, 2015-06-18)Hydrogen spillover represents one of the most promising avenues to achieve hydrogen storage at the density required for transportation applications. The spillover phenomenon, however, is a topic of much debate, with many ... -
3-Phenylpyrazino[1,2-a]indol-1(2H)-ones as dual cholinesterase and amyloid aggregation inhibitors
(University of Waterloo, 2017-05-10)The year 2017, marks the 110th anniversary of the discovery of Alzheimer’s disease (AD)- a devastating neurodegenerative disease. Regardless of the significant advances made in the past century on the pathology of AD, the ... -
3D printing of soft hydrogels incorporating functional nanomaterials
(University of Waterloo, 2017-01-10)Tissue engineering (TE) scaffolds are required to closely mimic the human body environment to enable the study of cell behavior in vitro and allow the fabrication of artificial tissue constructs. The scaffolds should possess ... -
400 kHz Spectral Domain Optical Coherence Tomography for Corneal Imaging
(University of Waterloo, 2021-12-23)The cornea is the transparent, outermost layer of the human eye that contributes approximately 70% of the refractive power of the eye in air. It is composed of five major tissue layers: the epithelium, the Bowman’s membrane, ... -
A 4d Lorentzian Spin Foam Model With Timelike Surfaces
(University of Waterloo, 2010-10-07)We construct a 4d Lorentzian spin foam model capable of describing both spacelike and timelike surfaces. To do so we use a coherent state approach inspired by the Riemannian FK model. Using the coherent state method we ... -
Above Bandgap Hyperpolarization Mechanism in Isotopically Purified Silicon and Optimal Bayesian Experiment Design for $T_1$ Estimation
(University of Waterloo, 2018-05-24)This thesis is concerned with the mechanism underlying the above bandgap illumination Dynamic Nuclear Polarization (DNP) of phosphorus donors in isotopically purified silicon-28. Two proposed DNP models are introduced and ... -
Abundance Matching with the Galaxies of the Virgo Cluster and the Stellar-to-Halo Mass Relation
(University of Waterloo, 2012-09-27)Using data from the Next Generation Virgo Cluster Survey and high-resolution simulations of Virgo cluster-like halos, we determine the stellar-to-halo mass relation (SHMR) for subhalos, using the technique of abundance ... -
Achievable Polarization for Heat-Bath Algorithmic Cooling
(University of Waterloo, 2015-08-17)Highly pure quantum states play a central role in applications of quantum information science, both as initial states for quantum algorithms and as resources for quantum error correction. Controlled preparation of pure ... -
Action Mechanism and Structural Studies on the Lipopeptide Antibiotic Daptomycin
(University of Waterloo, 2019-07-02)Daptomycin (dap) is calcium-dependent lipopeptide antibiotic that is used clinically to treat systemic infections caused by Gram-positive pathogens. It is thought that dap brings about its antimicrobial effect by binding ... -
Adaptation to near addition lenses - Effect of AV/A ratio and age
(University of Waterloo, 2007-05-17)AIM: The primary purpose of this thesis was to evaluate the pattern of changes to accommodation and phoria when pre-presbyopic individuals perform near work for 20 minutes with +2D lenses. In addition, the thesis also ... -
Advanced research on Lithium-Sulfur battery : studies of lithium polysulfides.
(University of Waterloo, 2013-10-03)This thesis was devised as a fundamental study of the Li-S system by the use of 7Li Magic Angle Spinning (MAS) Nuclear Magnetic Resonance (NMR), X-ray Absorption Near- Edge Structure (XANES), and Non-Resonant Inelastic ... -
Advances in Rock Core VOC Analyses for High Resolution Characterization of Chlorinated Solvent Contamination in a Dolostone Aquifer
(University of Waterloo, 2008-05-14)The current understanding of contaminant migration in fractured sedimentary rock aquifers is inadequate due to the difficulty in describing the geologic and hydrogeologic controls on contaminant fate and transport with ... -
Age Determination and Growth of Rainbow Darter (Etheostoma caeruleum) in the Grand River, Ontario
(University of Waterloo, 2016-05-31)The accurate determination and validation of age is an important tool in fisheries management. Age profiles allow insight into population dynamics, mortality rates and growth rates, which are important factors in many ... -
Algal priming mediates the effects of light and nutrients on organic matter processing: insights from artificial and natural streams
(University of Waterloo, 2023-10-31)Environmental factors such as light and nutrients may play important roles in determining detrital decomposition through their effects on primary production. Thus, human activities that alter the availabilities of light ... -
