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 ... -
Dissocation of Subjective and Objective Health Status in the Chinese Population
(University of Waterloo, 2011)As the general Chinese population becomes more overweight, pressure mounts to explore the reasons behind this trend. Pooling four waves of the Chinese Health and Nutrition Survey (CHNS) into two groups—2004 with 2006 and ... -
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 ... -
Dissociation and Degradation of Thiol-Modified DNA on Gold Nanoparticles in Aqueous and Organic Solvents
(American Chemical Society, 2011-05-17)Gold nanoparticles functionalized with thiol-modified DNA have been widely used in making various nanostructures, colorimetric biosensors, and drug delivery vehicles. Over the past 15 years, significant progress has been ... -
Dissolved inorganic carbon and alkalinity fluxes from coastal marine sediments: model estimates for different shelf environments and sensitivity to global change
(European Geosciences Union, 2013-01-24)We present a one-dimensional reactive transport model to estimate benthic fluxes of dissolved inorganic carbon (DIC) and alkalinity (AT) from coastal marine sediments. The model incorporates the transport processes of ... -
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 ... -
Dissolved organic carbon concentration and character in northern hardwood-dominated headwater catchments: A paired-catchment investigation of legacy harvesting impacts
(University of Waterloo, 2023-08-01)The water quality of forested source water regions can be degraded by natural and anthropogenic landscape disturbances such as wildfires and forest harvesting, the latter an economically important primary industry in Canada ... -
Dissolved organic carbon production and transport in a constructed watershed in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2018-01-23)Within the Western Boreal Plains, a significant amount of surface cover has been removed through open-pit oil sands mining activities, which includes fen peatlands. Fen construction has been performed on the post-oil sands ... -
Dissolved Organic Matter in the Anthropogenically Impacted Grand River and Natural Burnt River Watersheds
(University of Waterloo, 2012-01-03)Dissolved organic carbon (DOM) is one of the largest cycled organic carbon pools on Earth and an important biogeochemical factor in aquatic systems. DOM can act as an energy source for microorganisms, alter the depth of ... -
Dissolved Organic Matter in the Canadian Arctic & Sub-Arctic: Importance of DOM Quality & Quantity in a Warming Climate
(University of Waterloo, 2019-08-28)Dissolved organic matter (DOM) is a ubiquitous component of aquatic and terrestrial systems and an important constituent that can influence aquatic health and drinking water quality. For instance, DOM can act as an important ... -
Dissolved Oxygen Dynamics in the Dunnville Marsh on the Grand River, Ontario, Canada
(University of Waterloo, 2009-02-19)Dissolved oxygen (DO) is one of the most important environmental factors necessary to sustain aquatic life. The Southern Grand River is characterized with extensive marshes. This study focuses on the Dunnville Marsh in ... -
Dissonant Child: Grassroots Interfaith in a Multicultural Canada
(University of Waterloo, 2012-06-19)While Canada's increasing ethnic and racial diversity have received a great deal of attention in recent years, the pluralization of its religious makeup has been largely ignored. As a result, political and societal responses ... -
Distance Measurement-Based Cooperative Source Localization: A Convex Range-Free Approach
(University of Waterloo, 2013-08-19)One of the most essential objectives in WSNs is to determine the spatial coordinates of a source or a sensor node having information. In this study, the problem of range measurement-based localization of a signal source ... -
Distance Measures for Probabilistic Patterns
(University of Waterloo, 2020-01-07)Numerical measures of pattern dissimilarity are at the heart of pattern recognition and classification. Applications of pattern recognition grow more sophisticated every year, and consequently we require distance measures ... -
Distance, Gaze and the Intimacy Equilibrium Model in Audio/Video-Mediated and Face-to-Face Dyads
(University of Waterloo, 2023-10)This experiment, from 1976 but until now unpublished, focused on the Argyle-Dean Intimacy Equilibrium Model, to consider gaze and social distance in face-to-face and audio/video-mediated dyads. It was found that, during ... -

Distance-Biregular Graphs and Orthogonal Polynomials
(University of Waterloo, 2023-09-15)This thesis is about distance-biregular graphs– when they exist, what algebraic and structural properties they have, and how they arise in extremal problems. We develop a set of necessary conditions for a distance-biregular ... -
Distant agricultural landscapes
(Springer, 2015-04-01)This paper examines the relationship between the development of the dominant industrial food system and its associated global economic drivers and the environmental sustainability of agricultural landscapes. It makes the ... -
Distinction of Individual Lanthanide Ions with a DNAzyme Beacon Array
(American Chemical Society, 2016-06-24)Developing chemical probes to distinguish each lanthanide ion is a long-standing challenge. Aside from its analytical applications, solving this problem will also enhance our knowledge in metal ligand design. Using in vitro ... -
