Crosstalk Signaling Between cAMP and Calcium on the Leading Edge of Migrating Human Arterial Vascular Smooth Muscle Cells
Vascular smooth muscle cells (VSMCs) are phenotypically plastic. Thus, while the VSMCs in healthy blood vessels are ‘contractile’ and control vascular tone, these cells can increase their synthetic, migratory and proliferative ... -
Sustainable Masonry: Mortar Containing Biochar and Recycled Aggregate in Concrete Blocks
The building and construction industry is the third-largest producer of CO2 in Canada. Additionally, emissions from this industry are expected to go up by more than nine megatonnes of carbon dioxide equivalent (Mt CO2 eq) ... -
Advanced Devolatilisation model for Lagrangian particles in OpenFOAM
To study the devolatilisation process associated with coal combustion, computational fluid dynamics (CFD) is a very useful tool. The aim of this thesis is to accurately model coal devolatilisation at high temperatures ... -
Partial Molecular and Biochemical Characterization of a Sandhoff Mouse Model
Sandhoff Disease (SD) is a rare genetic disorder which results in progressive neurodegeneration. SD is caused by a build-up of GM2 Gangliosides, a lipid which is stored in the lysosome of neurons. It can occur in infantile, ... -
Witnessing Public Drinking and its Relevance to Discrimination Against Individuals Living With Alcohol Use Disorders
Objective: The primary goal of this study was to determine if a relationship existed between how often a person perceives public drinking in their neighbourhood and if they discriminate against individuals living with ... -
Expert Tattooing: The Development of a Profession in Canada, 1891-1986
Expert Tattooing: The Development of a Profession in Canada, 1891-1986 examines professional tattooing in Canada from the late nineteenth century to the mid 1980s, a period that saw the practice’s emergence, expansion, and ... -
Electrical Double Layer in Polar and Nonpolar Media in the Presence of Surfactants
The objective of this thesis is to improve our understanding of the concept of electrical double layer (EDL). The EDL is the basis of all electrokinetic phenomena. Despite numerous studies in the span of over a century, ... -
Evaluation of the hemostatic stress response in Type 1 von Willebrand Disease
Type 1 von Willebrand Disease (VWD) is an inherited bleeding disorder resulting from a quantitative deficiency in the procoagulant protein von Willebrand factor (VWF). Diagnosis is dependent on a reduction in VWF levels ... -
Motor Memories in Manipulation Tasks are Linked to Contact Events Between Objects
Humans have the remarkable ability to learn and perform motor skills, often involving the manipulation of different objects or tools, such as swinging a hammer or a tennis racket. The objects that we manipulate are usually ... -
Picking up good vibrations: Discrepant vibrator use, sexual functioning, and sexual well-being in women with male partners
(Taylor & Francis, 2019)Vibrator use is thought to be associated with positive sexual functioning for women with female or male partners. Vibrator use that is discrepant across contexts (i.e. the individual uses a vibrator in solitary but not ... -
Transfer of chirality from light to a Disperse Red 1 molecular glass surface
(Optical Society of America, 2017-08-30)Chiral structures and materials interact with light in well-documented ways, but light can also interact with achiral materials to generate chirality by inscribing its asymmetric configuration on photoresponsive materials, ... -
Structural, Optical, Electrochemical and Photovoltaic Studies of Spider Web like Silver Indium Diselenide Quantum dots Synthesized by Ligand Mediated Colloidal Sol-gel Approach
(Elsevier, 2017-08-04)Silver indium diselenide quantum dots were successively synthesized by colloidal sol-gel method by chelating with organic ligand oleylamine (OLA). The particle size was studied by transmission electron microscopy (TEM) and ... -
Investigating Chronic Pain Management Among Emerging Adults
Background: Emerging adulthood is the age between late teens into mid to late 20s. This transition is characterized by a lack of role permanence, where self-reliance and independence are sought. During this period, emerging ... -
Efficiency enhancement of ternary blend organic photovoltaic cells with molecular glasses as guest acceptors
(Organic Electronics, 2017-11-06)Previously reported glass-forming perylenediimide (PDI-glass) and diketopyrrolopyrrole (DPP-glass) acceptors were used as ternary components to modulate the morphology and electron transport properties of bulk heterojunctions ... -
Searching for Evidence of Optical Rectification: Optically-Induced Nonlinear Photovoltage in a Capacitor Configuration
(Optical Society of America, 2018-12-12)A current challenge in photonics is to design new versatile photodetectors based on optical rectification induced photo-voltage; these ones are more attractive than classical photodetectors because they do not rely on band ... -
Deceleration of thermal ring closure in a glass-forming mexylaminotriazine-substituted merocyanine (MC) linked to intramolecular hydrogen bonding
(RSC, 2016-12-21)The design and synthesis of a glass-forming nitrobenzospiropyran (SP) functionalized with a mexylaminotriazine group is reported herein. The title compound was synthesized in 63% overall yield by the carbamylation of a ... -
Fabrication of planar heterojunction CsPbBr2I perovskite solar cells using ZnO as an electron transport layer and improved solar energy conversion efficiency
(RSC, 2018-06-26)Inorganic lead halide perovskite solar cells with mixed halides have achieved reasonable power conversion efficiency with the advantage of an enhanced stability. In this work, we report the fabrication of an all inorganic ...
