Examining oil sands dissolved carbon and microbial degradation using stable isotope analysis
(University of Waterloo, 2007-05-22)Oil sands mining operations in northeastern Alberta are rapidly expanding. Upgrading and extracting the bitumen from the sand requires large volumes of water generating large quantities of oil sands process water/materials ... -
Examining the growth and stable isotopes of phytoplankton and periphyton communities exposed to oil sands reclamation strategies
(University of Waterloo, 2013-01-28)The impacts of oil sands processed materials (OSPM) on phytoplankton and periphyton community growth and stable carbon and nitrogen isotopes were examined. Estimates of plankton and periphyton community growth, measured ... -
Examining the taxonomic identity of the green alga Oophila amblystomatis (Chlamydomonadales), the biogeography of its symbiont Ambystoma maculatum (Amphibia), and the response of the green alga to two herbicides
(University of Waterloo, 2016-09-02)The yellow spotted salamander (Ambystoma maculatum) shares a unique endosymbiotic relationship with the unicellular green alga Oophila amblystomatis. Though a number of studies have isolated and identified O. amblystomatis, ... -
Exercise-Induced Fatigue and Caffeine Supplementation Affect Psychomotor Performance but Not Covert Visuo-Spatial Attention
(Public Library of Science, 2016-10-21)Fatigue resulting from strenuous exercise can impair cognition and oculomotor control. These impairments can be prevented by administering psychostimulants such as caffeine. This study used two experiments to explore the ... -
Exodermal Function and Suberin Chemistry
(University of Waterloo, 2010-05-18)The thesis work concerns the multiseriate exodermis (MEX), an outermost cortical layer (two or more cell layers thick) characterized by Casparian bands and suberin lamellae. Diverse aspects of Iris germanica's MEX were ... -
Exotic Circuits for Enhanced Quantum Algorithms and Computation
(University of Waterloo, 2023-08-09)Quantum circuits play an essential role in many disciplines of quantum information science. They can not only be represented in the traditional gate-based paradigm, but also an alternative measurement-based paradigm. The ... -
An expanded shale δ98Mo record permits recurrent shallow marine oxygenation during the Neoarchean
(Elsevier, 2020-01-20)Multiple attempts have been made using the ancient shale record to track the molybdenum isotope composition (δ98Mo) of seawater during the final two-hundred million years of the Archean Eon (2.7 to 2.5 billion-years-ago, ... -
Expanding the bionanotechnology toolbox using an engineered bacteriophage M13 platform
(University of Waterloo, 2015-01-15)M13 is a filamentous virus which has received recent attention as a component for device and material applications. M13 phages have measurements of approximately 6 nm in width and 900 nm in length. M13 is composed of the ... -
Experimental and theoretical demonstration of the feasibility of global quantum cryptography using satellites
(University of Waterloo, 2014-10-15)Information security is a growing concern in our modern world, where almost everything can be done online. To protect security, classical encryption protocols, such as RSA, are used. These encryption protocols are almost ... -
Experimental and theoretical investigations of radio-frequency and optical trapping potentials for atomic ions
(University of Waterloo, 2020-10-08)Over the years, trapped ion have emerged as one of the premier candidates for universal quantum simulation due to its long coherence time, low initialization and detection errors, robust high-fidelity gate sets and fully ... -
Experimental characterization of a catalytically active flagellin variant in Clostridium haemolyticum
(University of Waterloo, 2017-04-18)The bacterial flagellum is made up of approximately 20,000 subunits of the monomeric protein, flagellin, and plays a role in cell motility and pathogenesis. The extreme sequence diversity within the hypervariable region ... -
Experimental determination of the extent of Fe(III) reduction and Fe isotope fractionation during microbial reduction of ferrihydrite in freshwater systems by sulfate-reducing bacteria
(University of Waterloo, 2017-12-15)Traditionally, sulfur was thought to have little influence on Fe cycling in freshwater systems because of the low sulfate concentrations (average ~ 0.2 mM) in such waters. However, a recent study suggested that a cryptic ... -
