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 ... -
Gauge Models of Topological Phases and Applications to Quantum Gravity
(University of Waterloo, 2018-06-26)In 2+1 dimensions, gravity is an SU(2) topological gauge theory that can be written as BF theory. In the condensed matter literature, the Hamiltonian realization of BF theory for finite groups is known as the Kitaev model. ... -
Gauge Theory Dynamics and Calabi-Yau Moduli
(University of Waterloo, 2014-07-02)We compute the exact partition function of two dimensional N=(2,2) supersymmetric gauge theories on S². For theories with SU(2|1)_A invariance, the partition function admits two equivalent representations corresponding to ... -
Gaze strategies for coping with glare under intense contra light viewing conditions – A pilot study
(University of Waterloo, 2011-09-30)Purpose: This is a pilot study to investigate gaze strategies for coping with glare when performing a simple visual task under intense contra light viewing conditions. Method: Twenty-four normally sighted participants ... -
Gem-Difluorination of α-Diazo Amides Using (Difluoroiodo)toluene
(University of Waterloo, 2017-09-25)Fluorination chemistry is a branch of study that appeals to the pharmaceutical and agricultural industries. Drawbacks of popular methods of forming carbon-fluorine bonds include high cost or hazardous conditions that are ... -
Generalized holographic dualities for metric gravity & Quantum geometry based on area variables
(University of Waterloo, 2020-09-18)Holography holds promise for simplifying computations in quantum gravity. In part I of this thesis, we construct holographic boundary theories for linearized gravity, for a general family of finite or quasi-local boundaries, ... -
Generating Functionals for Spin Foam Amplitudes
(University of Waterloo, 2014-09-25)Various approaches to Quantum Gravity such as Loop Quantum Gravity, Spin Foam Models and Tensor-Group Field theories use invariant tensors on a group, called intertwiners, as the basic building block of transition amplitudes. ... -
Generation of Short Laser Pulses by Using Hollow Fibre and Chirped Mirror Compressor System
(University of Waterloo, 2017-10-23)A FEMTOLASERS hollow core silicon fibre of length 1 m and 250μm inner diameter was set up in the lab in Waterloo with the purpose of generating sub 10fs pulses for Coulomb Explosion Imaging (CEI). The input laser was a new ... -
Generational Effects of Bisphenol A on Growth and Stress Performance in Rainbow Trout
(University of Waterloo, 2014-06-25)The aquatic environment is severely impacted by xenobiotics that are released due to anthropogenic activities, threatening ecosystem health. Some of these contaminants accumulate in lipophilic fish tissues and are maternally ... -
Genesis of a giant Paleoproterozoic strata-bound magnesite deposit: Constraints from Mg isotopes
(Elsevier, 2016-08-01)Giant strata-bound magnesite deposits are absent in modern and most Phanerozoic sedimentary environments but occur predominantly in Precambrian strata. These deposits may have formed directly through precipitation of evolved ... -
The Genetic Analysis of Autophagy-Dependent Caspase Activation in Drosophila melanogaster
(University of Waterloo, 2009-10-23)During Drosophila melanogaster pupation, groups of undifferentiated adult cells proliferate and undergo regulated cell shape changes, while larval tissues are eliminated by programmed cell death (PCD). PCD is most commonly ... -
Genome analysis reveals unexpected absence of oxygen metabolic capacity in helminths
(University of Waterloo, 2022-07-06)Oxygen metabolism in parasitic helminths differs significantly from that of most aerobic eukaryotes, as these organisms must be able to switch between aerobic and anaerobic metabolisms depending on their life-cycle stage. ...
