(University of Waterloo, 2018-10-22)OBJECTIVE: The successful perception of a target location is critical for everyday reaching behaviours. Visually-guided goal-directed action involves successful coordination of both eyes and upper limb movement execution. ... -
The Effect of Season of Fire on Post-fire Legacies in Northwestern Ontario Red Pine (<em>Pinus resinosa</em>) Mixedwoods
(University of Waterloo, 2005)Prescribed burns are employed in the southern boreal forest of northwest Ontario, Canada, as a method of re-instating fire in this fire-dependent landscape. They are also used to manage fuel loads associated with tree ... -
The Effect of Selected Coagulants on Chloride-to-Sulfate Mass Ratio for Lead Control and on Organics Removal in Two Source Waters
(University of Waterloo, 2009-01-22)Lead is a known toxin, with the ability to accumulate in the human body from as early as fetal development. Lead exposure is known to cause a myriad of health effects which are more prominent among children. Health effects ... -
The Effect of Several Tradeoffs in the Implementation of Large Displays on the Performance of the Users of the Displays
(University of Waterloo, 2015-10-05)A large display can be constructed in two different ways: 1. a rectangular grid, or tiling, of many small screens with seams, or bezels, at the boundaries between the screens and 2. one large screen with no bezel inside ... -
The Effect of Shock Metamorphism on Zircon of the Huronian Supergroup in proximity to the Sudbury Impact, Ontario, Canada
(University of Waterloo, 2019-09-26)U-Pb geochronology of zircon is a widely used tool, but damage to the crystal lattice of zircon and loss of Pb by impact-related shock metamorphism can affect the interpretation of U-Pb isotope data. Five samples of the ... -
The Effect of Shot-peening on the Fatigue Limits of Four Connecting Rod Steels
(University of Waterloo, 2010-08-31)This work was carried out to study the effect of shot-peening on the fatigue behaviour of carbon steels. Differently heat treated medium and high carbon steel specimens were selected. Medium carbon steels, AISI 1141 and ... -
Effect of Silica Nanoparticles on Interfacial Tension and Crystallization of Poly(lactic acid) in Supercritical Carbon Dioxide
(University of Waterloo, 2016-04-12)In this thesis, the effect of silica nanoparticles on two of the most important parameters in the foaming of poly (lactic acid) (PLA) was studied: interfacial tension and crystallization. According to classical nucleation ... -
The Effect of Socializing During Exercise on Psychological Need Satisfaction, Motivation to Exercise, and Wellbeing
(University of Waterloo, 2013-06-20)Previous research has indicated that exercising with other people improves interest and engagement in physical activity (e.g., Christensen, Schmidt, Budtz-Jorgensen, & Avlund, 2006; Estabrooks & Carron, 1999). However, the ... -
The effect of soil moisture and oxygen content on naphthalene biodegradation
(Global Water Futures, 2023-05-15)Petroleum hydrocarbon (PHC) contamination of soil and groundwater is a serious threat to ecosystems and natural resources worldwide. Biodegradation is a key process contributing to the natural attenuation and remediation ... -
The Effect of Solids Residence Time on Phosphorus Uptake in Co-precipitation Systems Targeting Low Phosphorus Concentrations
(University of Waterloo, 2015-04-07)Chemical phosphorus (P) removal is generally considered to be necessary when attempting to achieve ultra low P concentrations (i.e. < 50 μg/L) in wastewater treatment. However, the impact of aging of chemical solids (i.e. ... -
The Effect of Spironolactone on Cerebral Blood Flow and Cognition
(University of Waterloo, 2018-03-23)Hypertension and arterial stiffness are associated with structural and functional changes in cerebral circulation and cognitive function, but based on existing evidence the effects are potentially reversible by spironolactone ... -
The Effect of Strategic Language on Perceptions of Actions and Speakers
(University of Waterloo, 2023-07-31)Describing the actions of others (or oneself) necessitates that a speaker make linguistic choices, as multiple terms can often be used to describe the same act. The present work investigates the consequences of these ... -
