The use of stable carbon and oxygen isotopes to examine the fate of dissolved organic matter in two small, oligotrophic Canadian Shield lakes.
(University of Waterloo, 2010-02-12)Allochthonous carbon can be a large proportion of the carbon budget in northern temperate and boreal lakes. This thesis uses stable carbon and oxygen isotopes to examine the fate of allochthonous dissolved organic matter ... -
The use of stable isotopes to assess the controls on pelagic carbon basal resources in Canadian Shield lakes
(University of Waterloo, 2021-06-02)Freshwater lakes are often natural sources of greenhouse gases (GHGs) such as carbon dioxide (CO₂) and methane (CH₄) to the atmosphere, and therefore it is important to examine carbon and nutrient cycling in these complex ... -
The use of stable nitrogen and carbon isotopes to examine the sources, sinks and cycling of nitrogen in a small, artificially eutrophic Boreal lake
(University of Waterloo, 2012-05-22)This research examines components of nitrogen cycling in the artificially eutrophic Lake 227 at the Experimental Lakes Area. The components are: 1) the atmospheric sources of nitrogen to the lake through precipitation and ... -
Use of Supercritical Propylene to Produce Polypropylene/Clay Nanocomposites via in situ Polymerization
(University of Waterloo, 2014-05-02)Nanocomposites have been receiving a lot the attention in the last decade from both industry and academia, since a small amount of nanofiller can significantly improve the materials properties. In the field of thermoplastics, ... -
Use of Technological Tools for Supporting Interpersonal Trust: From Modelling to Fostering Trust Through Design
(University of Waterloo, 2014-05-15)Trust is a core construct of our social lives, influencing how we interact with other individuals that are part of our social circle. Whether at work, in teams, or with friends and family, trust influences how much information ... -
The Use of Temperature and Environmental Isotopes as Tools to Characterize Groundwater Discharge to the Grand River, Ontario, Canada
(University of Waterloo, 2013-01-25)The Grand River Watershed, in southern Ontario, is home to approximately 900,000 people and one of the fastest growing regions in Canada; specifically, in the urban areas of Guelph, Cambridge, Kitchener, and Waterloo. ... -
The Use of the Internet in Distributing Packaged Software
(University of Waterloo, 2006)To reflect common practice in the software industry and extend transaction cost theory, this research developed building on previous research and empirically tested a model based on to identify conditions in which software ... -
Use of the interRAI Acute Care Assessment Instrument to Predict Adverse Outcomes Among the Hospitalized Elderly
(University of Waterloo, 2010-09-01)Abstract Objectives: This research project was undertaken to review two commonly used screening instruments for the elderly who attend at hospital emergency departments in Ontario. These instruments were then contrasted ... -
Use of the interRAI CHESS Scale to Predict Mortality among Persons with Neurological Conditions in Three Care Settings
(Public LIbrary of Science, 2014-06-10)Background: Persons with certain neurological conditions have higher mortality rates than the population without neurological conditions, but the risk factors for increased mortality within diagnostic groups are less well ... -
A Use of the Theory of Planned Behaviour to Determine the Social Barriers to the Implementation of Stormwater Green Infrastructure on Private Properties in Dundas, Hamilton, Ontario
(University of Waterloo, 2017-12-22)Climate change has resulted in more extreme rainfall events and most municipalities’ stormwater infrastructure is not prepared to deal with the increased flooding instances that may be associated with the increased rainfall. ... -
The Use of Traditional Environmental Knowledge to Assess the Impact of Climate Change on Subsistence Fishing in the James Bay Region, Ontario, Canada
(University of Waterloo, 2010-05-21)This thesis used traditional environmental knowledge (TEK) to assess the impacts of climate change on food security for First Nations communities located in the western James Bay region of northern Ontario. In addition, ... -
Use of Water Isotope Tracers to Characterize the Hydrology of Prairie Wetlands in Alberta
(University of Waterloo, 2018-01-22)Our understanding of prairie wetland hydrology comes primarily from a handful of long-term research stations, but generalizing from a few intensively monitored areas to the entire prairie pothole region requires assumptions ... -
Use of water isotope tracers to elucidate hydrological conditions of lakes in the Peace-Athabasca Delta over space and time: A foundation for lake ecosystem monitoring
(University of Waterloo, 2022-01-17)Hydrological monitoring in complex, dynamic northern floodplain landscapes is challenging but increasingly important as these ecosystems come under threat from multiple stressors, including climate-driven decline in ... -
Use-Bounded Strong Reducibilities
(University of Waterloo, 2009-08-20)We study the degree structures of the strong reducibilities $(\leq_{ibT})$ and $(\leq_{cl})$, as well as $(\leq_{rK})$ and $(\leq_{wtt})$. We show that any noncomputable c.e. set is part of a uniformly c.e. copy of ... -
USER EXPERIENCE WITH MEDICATION ADHERENCE TECHNOLOGY: DETERMINING USABILITY BY CAPABILITIES
(University of Waterloo, 2024-05-27)Background: As populations worldwide grow older, the prevalence of chronic conditions and the complexity of managing multiple medications significantly increase. This challenge is further complicated by a range of barriers ... -
User Interface Design and Validation for the Automated Rehabilitation System
(University of Waterloo, 2015-10-27)In current physical rehabilitation protocols, patients typically perform exercises with intermittent feedback or guidance following the initial demonstrations from the physiotherapist. Although many patient-centered systems ... -
