(University of Waterloo, 2017-03-29)Large amounts of salts are applied every winter to highways, streets, parking lots and sidewalks. Despite its effectiveness, the use of salt has increasingly become a public concern because of the detrimental effect it has ... -
Evaluation of the Performance of Pervious Concrete Pavement in the Canadian Climate
(University of Waterloo, 2012-04-30)Pervious concrete pavement has the capacity to perform as two types of infrastructure: a pavement; and a stormwater management solution. It is a low impact development as it does not alter the natural hydrological cycle ... -
An evaluation of the potential effectiveness of tobacco-related health messages among Inuit in Nunavut, Canada: What types of messages work best at promoting smoking cessation among Inuit smokers?
(University of Waterloo, 2013-07-19)Background. Inuit experience some of the highest rates of tobacco use and of tobacco-related diseases in Canada. Communication strategies, such as health warnings on tobacco products, are seen as a necessary means of ... -
An Evaluation of the Reintroduction of Atlantic Salmon to Lake Ontario and its Tributaries
(University of Waterloo, 2010-09-22)As the field of restoration continues to develop, it is important that initiatives are evaluated for their effectiveness and to explore the motivations and justifications behind the projects‘ designs. Current restoration ... -
Evaluation of the Removal of Perfluoroalkyl Substances from Aqueous Matrices in the Presence of Zerovalent Iron
(University of Waterloo, 2018-01-17)Per- and polyfluoroalkyl substances (PFASs) are a class of persistent organic pollutants present in the environment that pose a threat to human health. PFASs primarily reside within aqueous phases and are present in ... -
Evaluation of the Role of Phospholipids in Fatty Acid Delivery to the Fetus During Pregnancy
(University of Waterloo, 2013-07-26)Docosahexaenoic acid (DHA) is an omega-3 highly unsaturated fatty acid that plays an important role in fetal brain development. The fetal demand for DHA appears to be met by placental transport and various maternal ... -
An Evaluation of the Safety and Operational Impacts of a Candidate Variable Speed Limit Control Strategy on an Urban Freeway
(University of Waterloo, 2006)Variable Speed Limit Sign (VSLS) systems enable transportation managers to dynamically change the posted speed limit in response to prevailing traffic and/or weather conditions. VSLS are thought to improve safety and ... -
An Evaluation of the Technical and Economic Performance of Weigh-In-Motion Sensing Technology
(University of Waterloo, 2007-09-11)Deteriorating roadway conditions have drawn attention to the need to develop an accurate and practical system to control increasing excessive traffic volumes and traffic loads. In practice, traffic volumes often exceed ... -
An evaluation of the water balance and moisture dynamics within Sphagnum mosses following the restoration (rewetting) of an abandoned block-cut bog
(University of Waterloo, 2011-09-30)Artificial drainage networks established throughout peatlands during the peat extraction process often remain active following abandonment, maintaining a water table relatively far from the surface of the peat and hindering ... -
Evaluation of Thoracic Response in Side Impact Crash
(University of Waterloo, 2010-11-29)Mitigating injury in side impact has been an important topic of research for decades. In the mid 1980’s the American government began a program intended to improve the crashworthiness of vehicles in side impact. This ... -
Evaluation of Traditional Hydrogeologic Characterization Approaches in a Highly Heterogeneous Glaciofluvial Aquifer/Aquitard System
(University of Waterloo, 2009-05-22)The purpose of this study was to evaluate the effectiveness of traditional hydrogeologic characterization approaches in a highly heterogeneous glaciofluvial aquifer at the North Campus Research Site (NCRS), situated on the ... -
An Evaluation of Trend and Anomalies of Arctic Sea Ice Concentration, 1979-2006
(University of Waterloo, 2013-05-23)As a part of the Cyrosphere ecosystem, Arctic sea ice is one of the focal points when studying Arctic climate change. Arctic sea ice image has been documented by remotely sensed data since the 1970s. By examining these ... -
Evaluation of two multi-component interventions for integrating smoking cessation treatments into routine primary care practice: a cluster randomized trial
(University of Waterloo, 2011-01-19)Background and Rationale: There is a well-documented practice gap in the rates at which evidence-based smoking cessation treatments are delivered to patients in primary care settings. Multi-component intervention that ... -
