Mechanisms of over-active endothelium-derived contracting factor signaling causing common carotid artery endothelial vasomotor dysfunction in hypertension and aging
(University of Waterloo, 2011-03-09)Background and Purpose: The endothelium is a single-cell layer positioned at the blood-vascular wall interface, where in response to blood-borne signals and hemodynamic forces, endothelial cells act as central regulators ... -
Mechanisms of the Aging-Related Positivity Effect in Memory and Attention
(University of Waterloo, 2012-05-16)According to the Socioemotional Selectivity Theory (SST), the normal aging process is associated with a greater emphasis on self-regulation of emotional states, and this fosters a bias in cognitive processing for information ... -
A mechanistic approach to assessment of the geochemical evolution of low sulfide mine-waste rock
(University of Waterloo, 2019-01-04)The potential for mine wastes to generate elevated concentrations of solutes including metals, sulfate, and reduced pH exists wherever mine-waste rock is stockpiled at the Earth’s surface representing one of the world’s ... -
A Mechanistic Derivation of The Monod Equation For Biofilm in Porous Media
(University of Waterloo, 2021-12-20)A mechanistic derivation of the Monod bioreaction equation is presented. The numerical model developed for this derivation involves four processes. 1)On the pore scale, substrate diffuses from the bulk aqueous phase crossing ... -
Mechanistic Framework for Risk Assessment of Cast Iron Water Main Fractures due to Moisture-Induced Soil Expansion
(University of Waterloo, 2021-07-09)North American water distribution networks are at significant risk of failure due to aging cast iron pipes. For instance, of the 650,000 kilometers of cast-iron pipes in active service in the United States and Canada, ... -
A mechanistic model of motion processing in the early visual system
(University of Waterloo, 2012-12-05)A prerequisite for the perception of motion in primates is the transformation of varying intensities of light on the retina into an estimation of position, direction and speed of coherent objects. The neuro-computational ... -
Mechanistic Role of ARNT/HIF-1β in the Regulation of Glucose-Stimulated Insulin Secretion
(University of Waterloo, 2014-04-29)Loss of glucose-stimulated insulin secretion (GSIS) from the pancreatic beta-cells is one of the earliest detectable defects in the pathogenesis of type 2 diabetes. However, despite its relevance, the mechanisms that govern ... -
Mechanistic Studies of Interface Formation Between AA3003 and AA4045 Alloys During Fusion™ Casting
(University of Waterloo, 2015-04-30)Fusion™ casting is a unique Direct Chill (DC) continuous casting process whereby two different alloys can be cast simultaneously, producing a laminated aluminum ingot. Empirically derived operating ranges exist for Fusion™ ... -
Mechano-chemical synthesis of amorphous manganese borohydride, the effect of catalytic additives on its hydrogen generation properties, and crystallization during solvent extraction
(University of Waterloo, 2016-10-13)Abstract This thesis forms one of the final parts of an extended study on the hydrogen storage and generation properties of metal borohydrides. Manganese borohydride, Mn(BH4)2, which is expected to be formed by the ... -
Mechatronic Design, Dynamics, Controls, and Metrology of a Long-Stroke Linear Nano-Positioner
(University of Waterloo, 2016-12-01)Precision motion systems find a broad range of application in various fields such as micro/nano machining tools, lithography scanners, testing and metrology machines, micro-assembly, biotechnology, optics manufacturing, ... -
Media multitasking and performance on attentionally demanding tasks
(University of Waterloo, 2017-07-31)This dissertation examined the behaviour of media multitasking, with a specific focus on three broad goals. The first goal, explored in Chapter 2, was to examine whether individual differences in the propensity to media ... -
Media multitasking and sustained attention
(University of Waterloo, 2014-08-25)Media multitasking describes a common, everyday behaviour that involves dividing or switching attention between multiple sources of media-based information. In the work reported here, I investigate the relation between ... -
Mediation: Resonating between the Organic and Inorganic
(University of Waterloo, 2020-05-29)This thesis emerges from the desire of unity between the intuitive and empirical expressions of nature. It argues for a greater understanding of 'patterns' inherent in nature and advocates for the need to see things as a ... -
Mediations of Shattered Water: Environmental Intimacy & the Dissolution of the Self
(University of Waterloo, 2017-05-09)In a time of accelerated environmental degradation, a human-centric approach to engagement has engendered a pervasive cultural passivity towards the environment. This fatalistic detachment amplified by technological advances ... -
The Medical Practice and Licencing of Women in the Late Medieval Kingdom of Naples
(University of Waterloo, 2020-10-21)This paper analyzes the medical licences of women from the Angevin Kingdom of Naples between the late thirteenth to early fifteenth century. While the Kingdom of Naples was home to the first known medical regulatory measures ... -
