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 ... -
Quantifying Greenhouse Gas Mitigation Measures during Provincial Highway Design, Construction, and Maintenance Activities
(University of Waterloo, 2020-12-18)In response to the increasing need to address global climate change, departments of transportation have adopted and promoted diverse mitigation measures to reduce source and enhance sinks of the greenhouse gas (GHG) emissions ... -
Quantifying Groundwater Recharge Under Dynamic Seasonality in Cold Climates
(University of Waterloo, 2018-01-18)Estimating groundwater recharge in cold climates during periods of dynamic seasonality such as winter melt periods and spring freshets is challenging due to subsurface heterogeneities and the complexity of vadose zone ... -
Quantifying Human Mental States in Physical Human-Robot Interaction
(University of Waterloo, 2024-04-23)To support independent living among older adults, we propose the introduction of robots as domestic service providers capable of assisting with daily activities like showering, toileting, and transferring. These tasks ... -
Quantifying Isothermal Solidification Kinetics during Transient Liquid Phase Bonding using Differential Scanning Calorimetry
(University of Waterloo, 2006)The problem of inaccurate measurement techniques for quantifying isothermal solidification kinetics during transient liquid phase (TLP) bonding in binary and ternary systems; and resulting uncertainty in the accuracy of ... -
Quantifying Location Privacy In Location-based Services
(University of Waterloo, 2018-10-24)Mobile devices (e.g., smart phones) are widely used in people's daily lives. When users rely on location-based services in mobile applications, plenty of location records are exposed to the service providers. This causes ... -
Quantifying Pavement Sustainability For Ontario Highways
(University of Waterloo, 2010-08-26)With the emerging trend of sustainability, sustainable infrastructure is highly regarded by the general public. Sustainable pavement is also a concept that has driven many research motivations today. These motivations ... -
Quantifying regional pectoralis major fatigue and its influence on performance of activities of daily living
