Use of Rainbow Trout Liver Cell Line (RTL-W1) to evaluate the toxicity of Heavy Fuel Oil 7102
(University of Waterloo, 2013-02-25)A rainbow trout liver cell line, RTL-W1, was used to evaluate the toxic potential of a heavy fuel oil (HFO) HFO 7102, and its fractions, which together with the HFO are referred to as the oil samples. The fractions were ... -
The Use of Risk Analysis Techniques to Determine the Probability of Producing Non-Compliant Drinking Water: Focusing on Dual Media Rapid Gravity Filtration
(University of Waterloo, 2006)The main goal of a drinking water treatment plant is to provide safe drinking water for its consumers. Historically, this was accomplished through monitoring the influent and effluent water quality to ensure that the ... -
THE USE OF SCIENCE IN ENVIRONMENTAL POLICY MAKING AND THE IMPLICATIONS FOR HEALTH: A CASE STUDY OF BISMUTH SHOTSHELLS
(University of Waterloo, 2005)Scientific information is required to make environmental policy that will enhance and protect the health of ecosystems. The issues placed on the policy agenda come from the interactions amongst stakeholders, decision ... -
Use of Sensors for Fire Detection and Monitoring
(University of Waterloo, 2019-05-17)The ultimate goal of placing fire detection systems in buildings and structures is to allow for the rapid detection of fire and accurate prediction of ensuing fire behavior. Through a-priori prediction of how a fire might ... -
The Use of Shear Wave Elastography to Estimate the Mechanical Properties of the Soft Tissues Surrounding the Proximal Femur
(University of Waterloo, 2023-08-28)Introduction: Falls are the leading cause of injury, morbidity, and mortality amongst older adults nationally and worldwide, with 95% resulting in hip fractures. Previous studies have found that the soft tissues (subcutaneous ... -
Use of Slip Prediction for Learning Grasp-Stability Policies in Robotic-Grasp Simulation
(University of Waterloo, 2023-07-04)The purpose of prosthetic hands is to restore a portion of dexterity lost through upper limb amputation. However, a key capability of human grasping that is missing from most currently available prosthetic hands is the ... -
Use of Smart Technology Tools for Supporting Public Health Surveillance: From Development of a Mobile Health Platform to Application in Stress Prediction
(University of Waterloo, 2023-08-10)BACKGROUND Traditional public health data collection methods are typically based on self-reported data and may be subject to limitations such as biases, delays between collection and reporting, costs, and logistics. These ... -
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 ... -
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. ... -
