Impacts of COVID-19 on Ontario's Electricity Market
(University of Waterloo, 2022-01-05)The COVID-19 outbreak has not only threatened global health but has also significantly affected the energy sector. Most countries around the world have faced sudden changes in the electricity load as a result of the strict ... -
The Impacts of Diamond Mining to Peatlands in the James Bay Lowlands
(University of Waterloo, 2013-02-21)Approximately 7000 to 8000 years ago when Hudson Bay became ice-free the Tyrrell Sea flooded the Hudson basin and deposited fine grained marine sediments overlaying the previous glacial tills. Coincident with the ablation ... -
Impacts of Dredging and Brush Cutting of Paired Agricultural Drainage Ditches on GHG Emissions and Nutrient Filtration Capacity
(University of Waterloo, 2023-01-04)Agriculture provides many beneficial and essential ecosystem services. Along with these beneficial services, the conversion of natural ecosystems into heavily modified agricultural ecosystems is also a source of ... -
Impacts of Ethanol in Gasoline on Subsurface Contamination
(University of Waterloo, 2009-10-09)The increasing use of ethanol as a gasoline additive has raised concerns over the potential impacts ethanol might have on groundwater contamination. In North America, 10% ethanol is commonly being added to gasoline (termed ... -
Impacts of freeze-thaw processes on phosphorus release from a variety of cover crop species in a temperate climate
(University of Waterloo, 2018-04-30)Cover crops (CC) are grown by farmers as an agricultural best management practice (BMP) to improve soil health during the non-growing season (NGS), and potentially reduce soil erosion. Some managers have cautioned against ... -
The Impacts of Gameful and Interactive Technologies on Hindering or Promoting Self-regulation
(University of Waterloo, 2021-04-14)Self-regulation is the essential component of goal pursuit that allows us to make better decisions and resist temptation of unwanted desires, which ultimately impacts our well-being. It is essential to identify and ... -
Impacts of historical and projected climate changes on ice surfaces of the Tibbitt to Contwoyto Winter Road, Northwest Territories, Canada
(University of Waterloo, 2014-10-27)Seasonal ice and winter roads are a historically important part of the Canadian arctic transportation network. Constructed over frozen lakes, rivers, permafrost zones, and seasonally frozen ground, the roads service rural ... -
Impacts of Hydromodification and Sediment Supply Alterations on Bedload Transport and Bed Morphology in Urbanizing Gravel-bed Rivers
(University of Waterloo, 2017-08-18)Urbanization is known to change the hydrologic and sediment supply regimes of rivers, causing more frequent, flashier flood events (hydromodification) and a reduction and redistribution of sediment sources. Presently, the ... -
Impacts of implicit normative evaluations on stereotyping and prejudice
(University of Waterloo, 2009-09-22)The present research examined how other people’s evaluations towards social groups will develop and how these evaluations will affect discriminatory behaviour outside of conscious effort. By living in a society people are ... -
Impacts of Mixtures of Copper and 1,2-dihydroxyanthraquinone on Physiology and Gene Expression in Lemna gibba L.G-3
(University of Waterloo, 2008-08-21)Polycyclic aromatic hydrocarbons (PAHs) and metals are co-contaminants of aquatic environments near industrial and urbanized areas. Mixtures could result in synergistic toxicity impairing macrophyte growth and potentially ... -
Impacts of Psychrophilic Conditions on Anaerobic Membrane Bioreactors Treating Municipal Wastewater
(University of Waterloo, 2019-05-27)Three 5 L AnMBRs that incorporated submerged ZeeWeed® hollow fibre PVDF membranes with a nominal pore size of 0.04 µm and a nominal membrane surface area of 0.047 m2 were employed. The AnMBRs were operated at a solids ... -
Impacts of resource access road crossings on ecohydrology and carbon dynamics of boreal peatlands
(University of Waterloo, 2019-09-04)Resource access road crossings are expected to alter peatland ecohydrological properties by obstructing surface and sub-surface water flows, providing favorable conditions to stimulate microbial activity, and ultimately ... -
Impacts of seismic line restoration on CO2, CH4, and biomass
(University of Waterloo, 2021-10-21)Oil and gas exploration has resulted in over 300,000 km of linear disturbances, known as seismic lines, throughout boreal peatlands across Canada. Sites are left with altered hydrologic and topographic conditions that ... -
Impacts Of Seismic Line Restoration Techniques On Nutrient Biogeochemical Processes In A Boreal Fen
(University of Waterloo, 2021-12-23)Peatlands contain 40 cm or more of partially-decomposed plant matter and sequester carbon and nutrients. The disturbance of peatlands alters these ecological functions. Seismic lines, long cutlines in the forest created ... -
The Impacts of Solvents, Heat Treatments and Hole Injection Layers on the Electroluminescent Lifetime of Organic Light-Emitting Devices
(University of Waterloo, 2019-05-15)Since their invention over three decades ago, organic light-emitting devices (OLEDs) have attracted tremendous interest for display and solid-state lighting applications and have already been commercialized in smartphones, ... -
The Impacts of Stormwater Management on Hydromodification and Bedload Sediment Transport in a Gravel-bed Stream
(University of Waterloo, 2017-09-27)Global trends of increasing urbanization have led many researchers to attempt to quantify the resulting impacts on channel morphology and on the ecological health of urban channels. Overall, there has been a lack of research ... -
