Deformation History of the Black Bay Fault, Northwest Territories, Canada
(University of Waterloo, 2018-09-10)The Black Bay Fault is a major Paleoproterozoic, NE-SW-trending, crustal-scale feature that separates different tectonometamorphic domains of the southern Rae craton in the Canadian Shield. This structure extends from the ... -
Degradable starch nanoparticle assisted ethanol precipitation of DNA
(Elsevier, 2014-04-18)Precipitation of DNA from a large volume of aqueous solution is an important step in many molecular biology and analytical chemistry experiments. Currently, this is mainly achieved by ethanol precipitation, where a long-term ... -
Degradation of Chlorinated Butenes and Butadienes by Granular Iron
(University of Waterloo, 2007-09-18)Sites where 2-chlorobutadiene-1,3 (chloroprene) and 2,3-dichlorobutadiene-1,3 (DCBD) are synthesized for use in chlorobutyl rubber have the potential to release a mixture of at least five chlorinated butenes and butadienes ... -
Delineating Base Flow Contribution Areas for Streams: A Model Comparison
(University of Waterloo, 2012-06-21)This study extends the methodology for the delineation of capture zones to base flow contribution areas for stream reaches under the assumption of constant average annual base flow in the stream. The methodology is applied ... -
Demonstration and Validation of the Use of Passive Samplers for Monitoring Soil Vapor Intrusion to Indoor Air
(University of Waterloo, 2014-08-18)This thesis documents a demonstration/validation of passive diffusive samplers for assessing soil vapor, indoor air and outdoor air concentrations of volatile organic compounds (VOCs) at sites with potential human health ... -
Demonstration of a Tunable Coupler Suitable for Investigating Ultra-strong Coupling Light-matter Interactions in Superconducting Devices
(University of Waterloo, 2022-05-02)One of the most ubiquitous processes in nature is the interaction of matter and an electromagnetic field which is well described using the spin-boson model. These light- matter interactions are specified by an interaction ... -
Demonstration of Nitrate-Enhanced In Situ Bioremediation at a Petroleum Hydrocarbon Contaminated Site
(University of Waterloo, 2011-10-28)Alternative strategies involving in situ remediation technologies have been developed to assist with property clean up, however, cost-effectiveness and discrepancies in success rates and timeliness continue. The objective ... -
Density Functional Theory Calculations on the Sorption of Organoarsenicals onto Hydrated Iron (III) Oxyhydroxide Clusters
(University of Waterloo, 2017-01-23)Organic forms of arsenic are introduced into the environment by natural and anthropogenic processes and they pose a threat to human health. The fate of these pollutants depends on their interactions with reactive soils ... -
The Dependence of Halo Mass on Galaxy Size at Fixed Stellar Mass Using Weak Lensing
(University of Waterloo, 2017-04-24)Stellar mass has been shown to correlate with halo mass, but with significant scatter. The stellar mass-size and luminosity-size relationships of galaxies also show significant scatter in galaxy sizes for a fixed stellar ... -
The Dependence of Radio-Mode Feedback on Baryonic and Halo Mass
(University of Waterloo, 2014-08-26)Supermassive black holes launch powerful radio-synchrotron jets into the hot atmospheres of galaxy clusters, creating bubbles of displaced gas and driving shock fronts. These jets output a tremendous amount of energy, ... -
Depletion gels from dense soft colloids: Rheology and thermoreversible melting
(American Institute of Physics, 2014-08-01)Upon addition of small nonadsorbing linear polymers, colloidal glasses composed of large hard spheres melt and eventually revitrify into the so-called attractive glass regime. We show that, when replacing the hard spheres ... -
