Effect of Reclining on Retinal Thickness in Diabetes
(University of Waterloo, 2015-01-20)Purpose: Previous studies have shown diurnal variation in retinal thickness in patients with diabetic macular edema (DME) over the course of the day but the cause, presence and magnitude of this variation is controversial. ... -
The Effect of Religious Participation on Cognitive Function in Middle- and Old-Aged Adults: A Sequential Explanatory Mixed Methods Study of the Canadian Longitudinal Study on Aging
(University of Waterloo, 2019-12-05)Background: Preserving cognitive health is a crucial aspect of successful aging. Atypical cognitive decline is linked to the onset of dementia disorders such as Alzheimer’s disease. Even normal cognitive deterioration can ... -
The Effect of Sagittal Plane Mechanics on Anterior Cruciate Ligament Strain During Jump Landing
(University of Waterloo, 2015-01-09)The Anterior cruciate ligament (ACL) is an important ligament in the knee. Non-contact ACL injuries are a common occurrence among athletes, leading to large financial burdens and long term physical concerns. The underlying ... -
The Effect of Salient and Neutral Distractors on Hand-Eye Coordination during Goal-Directed Reaching
(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 ... -
