The use of plant functional traits to detect changes in urban wetland management regimes within Kitchener, ON
(University of Waterloo, 2019-08-14)Humans have modified their surrounding environment in ways that often lead to changes in ecosystem structure and function. Ecosystem management efforts are necessary to bring back functioning attributes of ecosystems for ... -
The use of plant growth promoting rhizobacteria to enhance phytoremediation of petroleum hydrocarbon-impacted soils
(University of Waterloo, 2011-09-30)Phytoremediation is a cost-effective and environmentally conscious technology that utilizes plants to remediate a variety of contaminants from the soil. Petroleum hydrocarbons (PHC), as a result of their widespread use are ... -
The Use of Plant Growth-Promoting Rhizobacteria (PGPR) and an Arbuscular Mycorrhizal Fungus (AMF) to Improve Plant Growth in Saline Soils for Phytoremediation
(University of Waterloo, 2008-01-18)Upstream oil and gas production has caused soil salinity problems across western Canada. In this work we investigated the use of ACC (1-aminocyclopropane-1-carboxylate) deaminase-producing plant growth-promoting rhizobacteria ... -
Use of prospective and retrospective risk assessment methods that simplify chemical mixtures associated with treated domestic wastewater discharges
(Wiley, 2018-03-01)A framework is presented that is intended to facilitate the evaluation of potential aquatic ecological risks resulting from discharges of down-the-drain chemicals. A scenario is presented using representatives of many of ... -
Use of rainbow trout cell lines to delineate the roles of p53 in fish and to evaluate the toxicity of emerging environmental contaminants, benzotriazoles and benzothiazoles
(University of Waterloo, 2015-05-01)Epithelial cell lines, RTgill-W1 and RTL-W1 from respectively the gill and liver of rainbow trout, Onchorhynchus mykiss (Walbum), were used to investigate the role of p53 in the cellular survival pathways of fish and to ... -
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 random forests to classify amyloid brain PET
(Wolters Kluwer Health, 2019-10)Purpose: To evaluate random forests (RFs) as a supervised machine learning algorithm to classify amyloid brain PET as positive or negative for amyloid deposition and identify key regions of interest for stratification. Methods: ... -
The Use of Random Forests to Identify Brain Regions on Amyloid and FDG PET Associated With MoCA Score
(Wolters Kluwer Health, 2020-06)Purpose: The aim of this study was to evaluate random forests (RFs) to identify ROIs on 18F-florbetapir and 18F-FDG PET associated with Montreal Cognitive Assessment (MoCA) score. Materials and Methods: Fifty-seven subjects ... -
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 ... -
