Disinfection By-Product Formation in Drinking Water Treated with Chlorine Following UV Photolysis & UV/H<sub>2</sub>O<sub>2</sub>
(University of Waterloo, 2005)ABSTRACT As far back as the early 1900?s when it was discovered that water could be a mode of transmitting diseases, chlorine was used to disinfect water. In the 1970?s, the formation of disinfection by-products ... -
Disk-based Indexing for NIR-Trees using Polygon Overlays
(University of Waterloo, 2024-01-23)This thesis presents the NIR+-Tree, a disk-resident R-Tree variant that eliminates overlap among its minimum bounding rectangles (MBRs). The NIR+-Tree is an extension of the main-memory NIR-Tree, adopting techniques for ... -
Dislocation Dynamics for High Strain-Rate Plasticity: Inertial and Thermal Effects
(University of Waterloo, 2017-07-26)There has been a trend of miniaturization in recent technological advances, particularly through the development of microelectromechanical systems (MEMS). To cope with the demand for increasing performance from ever smaller ... -
Disorder, Geometric Frustration and the Dipolar Interaction in Rare-Earth Magnets
(University of Waterloo, 2010-08-30)This thesis will present research that studies the role of disorder, geometric frustration and the long range dipolar interaction on the collective behaviour of several insulating, rare earth magnets. Experiments were ... -
Disorder-based Electromagnetic Devices
(University of Waterloo, 2019-01-23)Engineered complex media with unusual and exotic electrical properties, realized through subwavelength building blocks, are leading to the development of new applications and improved functionalities in a variety of fields. ... -
Dispatching Work: Finding the best dispatching method for real job-shops
(University of Waterloo, 2014-11-11)Motivated by a situation observed by our industry partner, we test if changing dispatch methods within a job-shop can reduce the percentage of late jobs while not reducing the maximum lateness across all jobs, the two ... -
Dispersion-cancelled imaging with chirped laser pulses
(University of Waterloo, 2013-06-20)This thesis deals with chirped-pulse interferometry, an interferometric imaging technique with a resolution which is unaffected by the normally detrimental effects of sample dispersion. The thesis begins with some important ... -
Displace and Urbanized: Or Why We Build
(University of Waterloo, 2019-01-11)I embarked on this research with the aim to study the relationship between the city and the flood, understanding the waterfront as some blurred edge where wild and human forces mix. My hope was to propose a design strategy ... -
Displays of Adaptive Body Image by Others: Examining Their Influence on College Women's Body Image
(University of Waterloo, 2021-03-10)The negative impact of interacting with others who display maladaptive body image has been well documented. Only recently have researchers started to examine adaptive body image, thus the interpersonal impact of displays ... -
Disposable rocking bioreactors for recombinant protein production in Escherichia coli: Physical characterization and assessment of therapeutic protein expression
(University of Waterloo, 2013-09-26)Disposable technology has gained increasing acceptance in the biopharmaceutical industry over the last decade, and provides many advantages over conventional stainless steel equipment. Disposable rocking bioreactors (RBs) ... -
The Disposal of Mine Tailings Material
(University of Waterloo, 2014-04-29)The mining industry is an important component of the Canadian economy. The principal waste material from this industry is tailings. Numerous failures of tailings dams have caused loss of life and serious pollution ... -
Dispositional Pathways to Trust: The Interactive Effects of Self-Esteem and Agreeableness on Trust and Negative Emotional Disclosure
(University of Waterloo, 2015-09-24)Expressing our innermost thoughts and feelings is critical to the development of intimacy (Reis & Shaver, 1988), but also risks negative evaluation and rejection. According to risk regulation theory (Murray, Holmes, & ... -
Dissimilar joining of Carbon/Carbon composites to Ti6Al4V and copper by reactive resistance spot welding
(University of Waterloo, 2017-08-30)This study aims to develop an innovative and user-friendly method for dissimilar joining of the carbon/carbon (C/C) composites to Ti6Al4V and copper through reactive resistance spot welding to form the hybrid structures. ... -
Dissimilar laser welding of NiTi shape memory alloys
(University of Waterloo, 2021-12-20)Welding of NiTi shape memory alloys has a great importance since it has a wide application in the medical industry due to the NiTi unique biocompatibility, superelasticity and shape memory effect. Laser microwelding is one ... -
Dissociating Response Prepotency and Response Conflict within Tasks of Action Inhibition among Individuals Scoring High on the Schizotypal Personality Questionnaire
(University of Waterloo, 2010-08-30)Theories embedded within evolutionary neurobiology offer useful frameworks within which to understand cognitive impairment in schizophrenia (SCZ). The current research invokes the Dual Trends Theory (DTT), an evolutionary ... -
Dissolved inorganic nitrogen cycling in a river receiving wastewater: the response to changes in wastewater treatment effluent
(University of Waterloo, 2016-01-27)Nitrogen is an essential element for all life forms, but when in excess in an aquatic ecosystem, it can cause an imbalance in the trophic status. A significant amount of nitrogen is released into the environment by wastewater ... -
