Evaluation Of Serogroup C And Acwy Meningococcal Vaccine Programs: Projected Impact On Disease Burden According To A Stochastic Two-Strain Dynamic Model
(Elsevier, 2015-01-01)Objective: Advisory committees in Canada and the United States have updated recommendations for quadrivalent meningococcal conjugate vaccines against serogroups A, C, W135, and Y. Our objective was to evaluate optimally ... -
Evaluation of the online Beverage Frequency Questionnaire (BFQ)
(Springer, 2018-08)Background The contribution of beverages to overall diet is of increasing interest to researchers and policymakers, particularly in terms of consumption of drinks high in added sugars; however, few tools to assess beverage ... -
Evaporation induced wrinkling of graphene oxide at the nanoparticle interface
(Royal Society of Chemistry, 2015-01-21)With the thickness of only a single atomic layer, graphene displays many interesting surface properties. A general observation is that wrinkles are formed on graphene oxide (GO) when it is dried in the presence of adsorbed ... -
Even pairs and prism corners in square-free Berge graphs
(Elsevier, 2018-07)Let G be a Berge graph such that no induced subgraph is a 4-cycle or a line-graph of a bipartite subdivision of K4. We show that every such graph G either is a complete graph or has an even pair. -
Event-based model calibration approaches for selecting representative distributed parameters in semi-urban watersheds
(Elsevier, 2018-08-01)The objective of this study is to propose an event-based calibration approach for selecting representative semi-distributed hydrologic model parameters and to enhance peak flow prediction at multiple sites of a semi-urban ... -
Evolution of a summer research/writing workshop for first‐year university students
(Emerald, 2008)Purpose: To describe a framework for a summer research/writing workshop for new university students, and its evolution over time and across institutions. Design/Methodology/Approach: The University of Toronto at Scarborough ... -
The Evolving Role of Liaison Librarians: Supporting Researchers in the Systematic Review Process
(2014-06-16)From the summer of 2013 to early 2014, four University of Waterloo librarians surveyed Health Sciences faculty and PhD students to gather data on their current and future systematic review work. Data provided insight into ... -
Ex-situ dissolution of CO2 for carbon sequestration
(Elsevier, 2013)In this paper, a model for diffusion-controlled dissolution of CO2 droplets during co-current (CO2-brine) horizontal turbulent pipe flow is presented. The objective is to evaluate the feasibility of ex-situ dissolution of ... -
An examination of how age of onset for alcohol, cannabis, and tobacco are associated with physical activity, screen time and BMI as students are preparing to graduate from high school
(Elsevier, 2019-09)Introduction In this study we examined the co-occurrence of alcohol, cannabis, and tobacco among a large cohort of grade 12 students in Canada, and then explored if the age of initiation of these substances was associated ... -
An Examination of Keyes Universal Chart: 50 Years Later
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2016-01)From the late 1940's to the late 1960's, significant efforts were made by ASHVE and then ASHRAE to evaluate and quantify the impact of window shading. In the context of the now defunct Shading Coefficient, well known ... -
Examining the Hospital Elder Life Program in a rehabilitation setting: a pilot feasibility study
(BioMed Central, 2016-07-18)Background: The Hospital Elder Life Program (HELP) has been shown to effectively prevent delirium and functional decline in older patients in acute care, but has not been examined in a rehabilitation setting. This pilot ... -
Examining the impact of timing of alcohol use initiation on changes to body weight and weight status among students in the COMPASS study
(Elsevier, 2019-12)Obesity rates among Canadian youth continue to be a concern, as weight issues during adolescence can transfer into adulthood, leading to long-term health problems. Current evidence lacks a consistent relationship between ... -
Executive functioning moderates associations between shyness and pragmatic abilities
(Wiley, 2020-09-26)While elevated shyness is associated with weaker pragmatic language abilities for some children, not all shy children demonstrate pragmatic challenges. Understanding the factors that may account for this variability is ... -
Exercise-Induced Fatigue and Caffeine Supplementation Affect Psychomotor Performance but Not Covert Visuo-Spatial Attention
(Public Library of Science, 2016-10-21)Fatigue resulting from strenuous exercise can impair cognition and oculomotor control. These impairments can be prevented by administering psychostimulants such as caffeine. This study used two experiments to explore the ... -
Existence and uniqueness of weak homotopy moment maps
(Elsevier, 2018-09-01)We show that the classical results on the existence and uniqueness of moment maps in symplectic geometry generalize directly to weak homotopy moment maps in multisymplectic geometry. In particular, we show that their ... -
An expanded shale δ98Mo record permits recurrent shallow marine oxygenation during the Neoarchean
(Elsevier, 2020-01-20)Multiple attempts have been made using the ancient shale record to track the molybdenum isotope composition (δ98Mo) of seawater during the final two-hundred million years of the Archean Eon (2.7 to 2.5 billion-years-ago, ... -
Expansion und Dynastische Politik in Pontos: Zwei neue Ären unter Pharnakes I.
(Steiner Verlag, Stuttgart, Germany, 2022-01-01)The most heated debates on early-Pontic history surround the treaty of alliance made between Pharnakes I and the citizens of Chersonesos in year 157 (IOSPE I2 402 = III3 103). About a half of the present generation of ... -
Expected utility of the drawdown-based regime-switching risk model with state-dependent termination
(Elsevier, 2018-03-01)In this paper, we model an entity’s surplus process X using the drawdown-based regime-switching (DBRS) dynamics proposed in Landriault et al. (2015a). We introduce the state-dependent termination time to the model, and ... -
Experiences of Food Insecurity Among Undergraduate Students: “You Can’t Starve Yourself Through School”
(Canadian Society for the Study of Higher Education, 2019-03)Canadian post-secondary students are vulnerable to food insecurity, yet lack of examination of this issue has prevented identification of policy and program solutions. This mixed-methods study aimed to characterize the ... -
Experimental and kinetic study of vacuum residue cracking over zirconium based catalysts
(Springer, 2022-04-01)In this study, thermal cracking and catalytic cracking over zirconium-based catalysts of the vacuum residue were achieved in the presence of supercritical steam at 400-450 degrees C, 20 bar, and 2-4 h. Two different catalysts ...
