Direct Brønsted acid-catalyzed functionalization of benzhydryl alcohols and 2-ethoxytetrahydrofuran using potassium trifluoroborate salts
(2016-06-01)Metal-free transformations of organotrifluoroborates are advantageous since they avoid using frequently expensive and sensitive transition metals. Lewis acid-catalyzed reactions involving organotrifluoroborates have emerged ... -
Discovery of trend dependencies over time-series
(2023-11-01)We improve constraint-based data quality using trend dependency (TD) discovery, extending existing order dependencies (ODs) to allow variations and exceptions. Unlike ODs, TDs capture approximate functional mappings between ... -
Discrete optimization of upgrade scheduling
(2022-08-01)A primary objective of the mission to meet climate change goals of reducing greenhouse gas (GHG) emissions is to transition from fossil fuels to zero-emission energy. Fossil fuel production and transportation account for ... -
DistGALO: Distributed system for query problem determination
(2019-12-01)Query optimization is a quintessential element of modern Database Management Systems(DBMSs). Compile-time driven estimates and heuristics aid the compiler in selecting what is deemed the lowest cost Access Plan for a given ... -
Do extroverts create stronger passwords?
(2018-04-01)We investigate the relationship between personality types and the strength of created and selected passwords. For this purpose, we conducted an experiment on Amazon’s Mechanical Turk, with 510 participants. Participants ... -
Dynamical effects in crystalline solid state systems: theory of temperature dependent optical response of bulk gaAs and vibrational modification of C(111) 2 x 1 Surface in Comparison to Experiment
(2009-08-01)This thesis presents a new theoretical formalism which incorporates dynamical effects in atomistic electronic structure and related calculations. This research, fundamental by nature, brings about a deeper understanding ... -
E-fencing detection: mining online classified ad websites for stolen property.
(2014-09-01)With the emergence of e-fencing, there presents a need to automate both the detection of ads selling stolen property and the reporting process for victims. This thesis presents a framework that dynamically retrieves and ... -
Echo: reconstructing gameplay sessions for analysis
(2021-04-01)We created Echo, a tool designed to help bridge the gap between game analytics and video footage analysis. Echo reconstructs gameplay sessions from recorded data and presents them with their original graphics. A comparative ... -
Effect of copper contamination at the cathode in Cu-Cl electrolyzers for hydrogen production
(2020-04-01)In this work the effects of copper contamination on the coulombic and voltage efficiency of the hydrogen evolution reaction (HER) via the Cu-Cl thermochemical cycle are investigated. A novel proton pump configuration was ... -
Effect of iron content on electrodeposited Fe-MnOx catalysts for water oxidation
(2018-04-01)MnOx materials are earth-abundant and known to be efficient catalysts for the water oxidation reaction (WOR). I present the exploration of an optimal method of cathodically electrodepositing MnOx catalysts on an FTO ... -
Effects of chronic exposure to ibuprofen and naproxen on Florida flagfish (Jordanella floridae) over one complete life-cycle
(2011-08-01)Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of drugs prescribed to relieve pain, fever and inflammation, and are among the most commonly consumed medications in Ontario. Approximately 70% of the ingested dose ... -
Effects of endosulfan on human MCF-7 breast cancer cells
(2011-08-01)Organochlorine pesticides (OCs) are environmental toxicants with important links to human health. They have been found to activate signalling pathways within cells and thereby affect cell survival and proliferation. Receptor ... -
The effects of Hydroxypropyl-β-Cyclodextrin on the American Flagfish (Jordanella floridae) over one complete life-cycle
(2013-08-01)Understanding the impacts of pharmaceuticals and personal care products (PPCPs) on aquatic ecosystems is an important issue in aquatic toxicology. Many PPCPs have been shown to cause effects on aquatic biota within detected ... -
Effects of ibuprofen on Rainbow Trout (Oncorhynchus mykiss) following acute and chronic waterborne exposures
(2011-08-01)Pharmaceuticals and personal care products are a growing concern in the aquatic environment. Compounds from the class of non-steroidal anti-inflammatory drugs are commonly detected in surface waters and have the potential ... -
Effects of per-and polyfluoroalkyl substances (PFAS) on the freshwater gastropod (Planorbella pilsbryi) in the laboratory and in situ integrating a multi-omic approach
(2023-09-01)Per- and polyfluoroalkyl substances (PFAS) are anthropogenic chemicals that are globally used in consumer and industrial applications. Specifically, perfluorooctane sulfonate (PFOS) has been under scrutiny due to its ... -
Effects of prebiotic fibre diets on rat mucosal intestinal and systemic immunity and in vitro mechanistic analysis of anti-inflammatory effects of lactobacillus strains on rat and human intestinal epithelial cells
(2012-08-01)Probiotics and prebiotics are emerging household terms, whose claimed health benefits share commonality. Their attributed health benefits include the production or induction of short chain fatty acids, maintaining bowel ... -
The effects of select non-steroidal anti-inflammatory drugs on green and brown hydra
(2014-04-01)Effluent pharmaceuticals are released at low concentrations into aquatic ecosystems through waste water treatment plants (WWTPs). Non-steroidal anti-inflammatory drugs (NSAIDs) are important contaminants in water cycles. ... -
