The functional significance of the alternative first exons of the Arabidopsis thaliana APT1 gene
(University of Waterloo, 2009-09-30)In plants, adenine nucleotides are essential for nucleic acid synthesis, as cofactors for biochemical reactions, and as precursors for the biosynthesis of the phytohormone cytokinin. Adenine nucleotides, such as AMP, are ... -
Functional Study of a Protein (UnkG) in Pseudomonas putida UW4
(University of Waterloo, 2011-07-20)The role played by the protein UnkG from the plant growth-promoting bacterium Pseudomonas putida UW4 in the ability of the bacterium to facilitate plant growth was studied. Previous work showed that over-expressing UnkG ... -
A Functional Study of Major Histocompatibility Expression and Immune Function in Rainbow Trout, (Oncorhynchus mykiss)
(University of Waterloo, 2006)Major Histocompatibility Complex (MHC) receptors serve a critical role in self/non-self recognition through the presentation of peptide antigen to circulating T lymphocytes and are also believed to play a role in mate ... -
A Functional Study of the Major Histocompatibility Class I Antigen Presentation Pathway in Rainbow Trout (Oncorhynchus mykiss)
(University of Waterloo, 2014-01-09)Major Histocompatibility Complex (MHC) class I receptors are glycoproteins which play a critical role in anti-viral immunity by displaying foreign peptides to cytotoxic T cell lymphocytes. The loading of high affinity ... -
Functionalization of spᶟ-Hybridized Carbon Centers through Carbon-Carbon σ Bond Cleavage Methods
(University of Waterloo, 2013-02-07)Methods for the modification and functionalization of spᶟ-hybridized carbon centers via cleavage of unstrained carbon-carbon σ bonds are proposed. The bond breaking/forming reactions are promoted by Lewis acids and transition ... -
Fundamental Tests of Quantum Mechanics using Two-Photon Entanglement
(University of Waterloo, 2014-04-30)In this thesis, we experimentally test fundamental properties of quantum mechanics, namely non-locality (in the form of three new families of Bell's inequalities) and the symmetry of envariance. To accomplish these we ... -
Fundamentals of Protein Adsorption at the Solid-Liquid Interface over Short Time Periods
(University of Waterloo, 2014-12-16)Purpose: To directly measure the quantity and degree of denaturation of biomaterial- adsorbed proteins over short time periods. Methods: Contact lenses were used as model biomaterials as they are widely used, readily ... -
Fundamentals of SPME extraction of tissue and plasma: experimental and in-silico approaches
(University of Waterloo, 2021-12-15)Over the last three decades, solid-phase microextraction (SPME) has continuously evolved and received recognition as a useful tool in various scientific fields. Notable applications have been published including environmental ... -
Further Development of Atmospheric Pressure, Self-Igniting Microplasma Devices (MPDs) for Elemental Analysis of Liquid Microsamples Using Atomic Emission Spectrometry (AES)
(University of Waterloo, 2011-05-26)The present elemental analysis workhorse worldwide is Inductively Coupled Plasma (ICP) Atomic Emission Spectrometry (AES) and Mass Spectrometry (MS). Due to the high power requirements, large gas consumption and the more ... -
G-Quadruplex DNA for Fluorescent and Colorimetric Detection of Thallium(I)
(American Chemical Society, 2016-02-26)Thallium is a highly toxic heavy metal, but its 495 nm FRET sensing is underexplored compared to its neighboring elements Blue in the periodic table: lead and mercury. Thallium has two " oxidation states. A DNAzyme-based ... -
Gaits and Their Development in the Infraorder Pecora
(University of Waterloo, 1967-02)The gaits of twenty-eight species of the Infraorder Pecora are analyzed from motion picture sequences comprising over 45,000 frames. For each gait the percentage time spent on the various supporting legs during each stride ... -
Galactic Molecular Dust Clumps using SCUBA-2 - Effects of HII Regions on Star Formation
(University of Waterloo, 2018-09-21)I present findings from a broad array of SCUBA-2 observations. The sample consists of 38 SCUBA-2 images targeted near mature, galactic, HII regions of the Sharpless "Sh-2" or Blitz-Stark-Fich "BFS" catalogue. In 31 of those ... -
Galaxy Formation at Redshift ~0.75: A Low Mass Survey & The Role of Environment
(University of Waterloo, 2011-09-29)The majority of galaxy formation studies which explore beyond local redshifts do not typically probe down to the dwarf galaxy stellar mass range of ∼ 10^9 Msun . Thus trends in the observed evolution or characteristics of ... -
Galaxy Morphology In Cluster Environments
(University of Waterloo, 2017-08-25)It is a well known fact that cluster environments favour early-type galaxies over late- type. However, the physical origin of the correlation remains uncertain. We focus specifically on the external environmental mechanisms ... -
Galaxy Transformations in the Last 5 Billion Years
(University of Waterloo, 2010-09-01)It has become clear that the global star formation rate in the Universe has been decreasing since at least z~1, and blue, star-forming galaxies are transformed into red, passive galaxies through one or more processes. The ... -
Gallium isotope fractionation during adsorption on clay and oxide minerals: implications for using gallium isotopes as a geochemical tracer
(University of Waterloo, 2022-05-02)Increasing climate change leads to the imbalance between silicate, sulfide, and carbonate weathering fluxes, influencing the global carbon budget. Thus, understanding this balance is critical for understanding future global ... -
Game play in virtual reality driving simulation involving head-mounted display and comparison to desktop display
(Springer, 2019-11-28)Previous studies have reported the effect of driving simulator games on simulator sickness and eye symptoms experienced by users; however, empirical results regarding the game experience using commercial virtual reality ... -
Garnet fractionation, progressive melt loss and bulk composition variations in anatectic metabasites: Complications for interpreting the geodynamic significance of TTGs
(Elsevier, 2020-05)Tonalite-trondhjemite-granodiorite (TTG) suites constitute a large proportion of the Archean geological record; however, the geodynamic processes that generated them, and Archean continental crust in general, remain a ... -
