Quality of Care Transitions for Rehabilitation Patients with Musculoskeletal Disorders
(University of Waterloo, 2010-08-24)Background: Care transitions are a common and frequently adverse aspect of health care, resulting in a high-risk period for both care quality and patient safety (Coleman, 2003; Forster et al., 2003; Picker Institute 1999; ... -
The quality of citizen scientists’ bee observations: An evaluation of PollinatorWatch at Royal Botanical Gardens and the rare Charitable Research Reserve
(University of Waterloo, 2014-02-12)Citizen science engages members of the nonscientific community in academic research, contributing to our collective knowledge of the natural environment through biological monitoring and environmental observations. Observation ... -
A Quality-Driven Approach to Enable Decision-Making in Self-Adaptive Software
(University of Waterloo, 2010-01-21)Self-adaptive software systems are increasingly in demand. The driving forces are changes in the software “self” and “context”, particularly in distributed and pervasive applications. These systems provide self-* properties ... -
Quality-Driven Cross-Layer Protocols for Video Streaming over Vehicular Ad-Hoc Networks
(University of Waterloo, 2011-08-31)The emerging vehicular ad-hoc networks (VANETs) offer a variety of applications and new potential markets related to safety, convenience and entertainment, however, they suffer from a number of challenges not shared so ... -
Quantification and Evaluation of Physical Shoulder Exposures in Police Mobile Data Terminal Operators
(University of Waterloo, 2009-09-30)Mobile police officers perform many of their daily duties within vehicles. Combined workspace inflexibility and prolonged driving exposure creates a risk for developing musculoskeletal issues. Limited research exists that ... -
Quantification and Profiling of Hepatic Retinoids in Freshwater Fishes by Liquid Chromatography – Tandem Mass Spectrometry
(University of Waterloo, 2018-03-26)Retinoids (vitamin A1) are a class of compounds essential for a number of physiological processes including vision and immune system function. They are stored as biologically inactive retinyl esters which are mobilized ... -
Quantification of Flare Combustion Efficiency through Mid-Wavelength Infrared Spectroscopy
(University of Waterloo, 2022-08-26)Flares convert unwanted hydrocarbon emissions into carbon dioxide to be disposed into the atmosphere. Although this conversion reduces the oil and gas industry’s greenhouse gas inventory, it is still responsible for ... -
Quantification of Oxygen Dynamics in the Grand River Using a Stable Isotope Approach
(University of Waterloo, 2010-04-30)The current study monitored DO, stable isotopes of O2 (δ18O-O2 and δ18O-H2O) along with water quality parameters on both a diel and day-time only basis in the Grand River over several seasons and locations. A dynamic dual ... -
Quantification of PFAS Fate in Sludge Handling Systems
(University of Waterloo, 2023-08-14)Per- and polyfluoroalkyl substances (PFAS) have been detected in biosolids, raising concerns regarding their potential leaching into soils, groundwater, and plants when biosolids are land applied. In this study, the fate ... -
Quantification of spine stability: Assessing the role of muscles and their links to eigenvalues and stability
(University of Waterloo, 2011-12-21)Approximately 50% - 80% of the population will experience disabling low back pain at some point in their life. Assessing and developing interventions based on “lumbar stability” and/or joint stiffness to reduce low back ... -
Quantification of the Long-Term Effects from Nutrient Reductions on Groundwater Nitrate Concentrations in an Agricultural Setting
(University of Waterloo, 2008-06-06)The Ontario Nutrient Management Act (2002) recommends agricultural Beneficial Management Practices (BMPs) that involve reductions in nutrient applications of nitrogen (N) to fields to improve underlying groundwater quality, ... -
Quantification of Upper Extremity Physical Exposures of Materials Handling Tasks in Seated and Standing Configurations
(University of Waterloo, 2014-04-30)Prolonged periods in sitting or standing may negatively influence worker health. Integration of sit-stand workstations has attempted to mitigate these deleterious effects, and has generated positive results in terms of ... -
Quantifying and Modelling Post-Wildfire Sediment Production in Waterton Lakes National Park
(University of Waterloo, 2021-12-16)High-severity wildfires can increase sediment mobility and erosion rates in burned landscapes which increase the delivery of fine sediment to receiving streams. The downstream propagation of these pyrogenic materials can ... -
Quantifying and predicting upper limb capability and dysfunction of breast cancer survivors
(University of Waterloo, 2014-12-15)Breast cancer will affect one in every nine Canadian women during their lifetime. As diagnostic and treatment methods improve, survival rates are approaching 90%. However, an alarming 30-82% of survivors suffer from ... -
Quantifying Aquatic Carbon and Nitrogen Dynamics and Greenhouse Gas Mitigation Potential in Riparian Agroforestry Zones
(University of Waterloo, 2023-03-27)Agricultural intensification in Canada has led to a loss of riparian areas, which has resulted in the degradation of freshwater aquatic ecosystems due to an increasing amount of fertilizer and nutrients being introduced ... -
Quantifying coniferous subalpine tree transpiration and source water under seasonal and hydrological stress in the Canadian Rocky Mountains, Kananaskis, Alberta
(University of Waterloo, 2019-06-04)Fresh water supplies in mountainous regions are at risk as snow and ice stores continue to decline under rising global temperatures, earlier winter snowmelt and changing climate regimes. Alpine forests are of particular ... -
