Social Justice Mathematics: Supporting and Encouraging Teaching Mathematics through a Social Justice Lens
(2021-04)The purpose of this project was to create a research-informed resource to help educators of Grade 4-6 students effectively integrate issues of social justice into their mathematics teaching. The Ontario mathematics ... -
Liquid Phase Exfoliation of Graphite into Graphene Nanoplatelets using Graphene Oxide as Surfactant
In this study, graphene nanoplatelets (GNP) are prepared using graphene oxide (GO), a derivative of graphene, as the dispersing agent in the liquid phase exfoliation of raw fake graphite. Graphene oxide has similar properties ... -
A Series and Parallel Tuned DC-DC Resonant Converter with Hybrid Modulation
Series and parallel tuned resonant converters have traditionally been operated at a constant frequency by employing Phase-Shift Modulation (PSM). It provides excellent efficiency from full - load to near no - load while ... -
Temperature’s Effect on the Speed of Light
(2021-05-04)In this experiment, our group investigates the effect of temperature on the speed of light by experimentally measuring the change in the angle of refraction through common glass over a 100C range in temperature while ... -
The enhanced Forward Presence: innovating NATO's deployment model for collective defence
(NATO Defense College, 2019-10) -
Desiring, Departing, and Dying, Affectively Speaking: Epithymia in Philippians
(The Bible and Critical Theory, 2019)In a text that has caused no shortage of speculation and consternation, Paul links “desire” (epithymia) with “death” in writing of his “desire to depart and be with Christ” (Phil. 1:23). While “desire” has mostly negative ... -
For Boredom: A Conceptual Network of Cultural Objects
(Capacious: Journal for Emerging Affect Inquiry, 2020) -
Dynamic Modelling for the Design of Head-Neck Load Carriage Systems
Head load-carriage systems have broad application, allowing people to carry awkward or heavy loads, but can cause chronic pain when the neck is loaded improperly. Studies have identified military helicopter crew neck pain ... -
Capacitance performance of NiO thin films synthesized by direct and pulse potentiostatic methods
(Springer, 2019-07-20)Transition metal oxides have applications into energy storage devices such as electrochemical supercapacitors. We deposited nickel oxide (NiO) thin films using electrodeposition under direct and pulse potentiometry. The ... -
Enhancement of the capacitance properties and the photoelectrochemical performances of P3HT film by incorporation of nickel oxide nanoparticles
(Springer, 2018-11-15)P3HT films were modified by incorporation of different amounts of nickel oxide (NiO). The nickel oxide powder was synthe- sized by chronoamperometry. The composites were further dissolved and deposited by the spin-coating ... -
Photonic crystal based broadband graphene saturable absorber
(OSA Publishing, 2019-10-01)The enhanced saturable absorption (SA) of a one- dimensional (1D) photonic crystal (PC) made from polymers and graphene composites by spin-coating is observed. It shows obvious bandgaps at two wavelengths in transmittance. ... -
Voyageur Philosophers: Exploring Canoe Expedition Pedagogy
In Canada, the canoe is an integral part of the history and development of nationhood (Raffan, 1999), a vital part of its leisure and tourism industry (Stebbins, 2005), and a central focus of many summer camps and outdoor ... -
Synthesis and properties of alumina-hydroxyapatite composites from natural phosphate for phenol removal from water
(Elsevier, 2019-07-01)Phenol is very abundant in the aquatic environment and therefore requires an effective treatment using porous and low-cost adsorbents. Alumina-hydroxyapatite composites were prepared from natural phosphate ore in the ... -
Development of sulfonate-functionalized hydroxyapatite nanoparticles for cadmium removal from aqueous solutions
(Elsevier, 2019-05-01)Sulfonate-functionalized hydroxyapatite was successfully synthesized by organo- functionalization using natural phosphate and Benzenedisulfonate molecules. The modified apatites were characterized using multiple techniques, ... -
The Practice of Tax in Canada: Understanding the Community, the Work and Structural Initiatives of an Emergent Profession
Considering it as a distinct occupation, I investigate the practice of tax in Canada through three separate studies. My first study examines the community of tax practitioners. Using a mixed-method approach, I integrate ... -
Detecting changes in cognitive load through audified EEG
Concussion is an increasing concern in society, especially with the popularity of contact sports. New research continues to show the dangers of letting concussions go undetected and untreated. Current assessment methods ... -
How early career experiences shape teachers' approaches to classroom assessment
In order to enhance the use of high-quality assessment practices to support student learning, it is critical to understand how early career experiences influence teachers’ approaches to assessment. Early career experiences ... -
CHARACTERIZATION OF THE AGE-DEPENDENT CHANGES IN HUMAN HEMATOPOIETIC STEM AND PROGENITOR CELLS
Biological aging leads to a reduced capacity of hematopoietic stem/progenitor cells (HSPCs) to efficiently produce blood and immune cells, which contributes to various age-related pathologies. Further understanding of this ... -
Efficacy of recreational watercraft decontamination practices to prevent the spread of aquatic invasive species.
The spread of aquatic invasive species (AIS) is a threat to the biodiversity and ecosystem services of invaded environments, and human activities largely facilitate their dissemination. Recreational boating activities ...
