Geochemical and Microbiological Characterization of the Historic Waste Rock Piles at the Detour Lake Gold Mine
(University of Waterloo, 2016-09-16)Four of the historic waste rock stockpiles (WRS #1-#4) at the Detour Lake mine site were studied to determine the potential for generation of acid rock drainage (ARD). The stockpiles were constructed during the original ... -
Geochemical Characterization and Assessment of Stabilization Mechanisms for Mercury-Contaminated Riverbank Sediments from the South River, Virginia (USA)
(University of Waterloo, 2013-04-29)Elevated concentrations of mercury (Hg) in aquatic systems can be a threat to ecosystems and human health. Mercury-bearing sediment particles from eroding riverbanks can be an ongoing source of bioavailable Hg to aquatic ... -
Geochemical Characterization and Longevity Estimates of a Permeable Reactive Barrier System Remediating a 90Sr plume
(University of Waterloo, 2013-01-25)In 1998, a permeable reactive barrier system was installed at the Atomic Energy of Canada Ltd. (AECL) Chalk River Laboratories in Chalk River, Ontario, to prevent the discharge of a 90Sr plume into a nearby swamp. The ... -
Geochemical Characterization of Groundwaters, Surface Waters and Water-Rock Interaction in an Area of Continuous Permafrost Adjacent to the Greenland Ice Sheet, Kangerlussuaq, Southwest Greenland
(University of Waterloo, 2016-01-21)Continental scale glaciations, such as those that covered much of Canada and Northern Europe during the last glacial maximum (26,000 to 19,000 y BP), can be expected to cause large disturbances to both the surficial and ... -
Geochemical Evolution of Fracture Filling Minerals from the Chalk River Laboratory Site, Ontario, Canada
(University of Waterloo, 2016-02-18)The isotope geochemistry combined with fluid inclusion studies of several generations of fracture minerals from the Chalk River Laboratory site (CRL) has been applied to investigate the past fluid evolution including ... -
A Geochemical Study of the Mineralization at the Hopper Property, Yukon: A Case Study of an Atypical Copper Occurrence
(University of Waterloo, 2010-07-19)The Hopper property is located in the Yukon Tanana terrane in the southwestern Yukon. It is characterized by granodiorite-hosted copper and molybdenum mineralization that is related to propylitic alteration and shearing. ... -
Geodesic Convex Analysis of Group Scaling for the Paulsen Problem and the Tensor Normal Model
(University of Waterloo, 2021-11-18)The framework of scaling problems has recently had much interest in the theoretical computer science community due to its variety of applications, from algebraic complexity to machine learning. In this thesis, our main ... -
Geographic and Demographic Suitability of Cycling in North American Cities
(University of Waterloo, 2022-09-13)With interest in cycling increasing in recent decades, local authorities and planners have been eager to enact policies to expedite a mode shift from driving to more sustainable, equitable and accessible transportation ... -
A Geographic Exploratory Analysis of Health and Crime in Toronto Neighbourhoods
(University of Waterloo, 2016-08-12)Crime impacts may pose a health risk to victims and result in potential demands on healthcare services. However, the impacts from crime on health are complex and diverse. It is difficult to measure and quantify such impacts, ... -
The Geographical and Spatial Imaginings of Islamist Extremism/Terrorism
(University of Waterloo, 2005)The contemporary Islamist extremist/terrorist phenomenon has emerged as one of the most significant threats to both regional and international peace, security, and stability. As the international community struggles to ... -
Geographically Distributed Database Management at the Cloud's Edge
(University of Waterloo, 2017-08-24)Request latency resulting from the geographic separation between clients and remote application servers is a challenge for cloud-hosted web and mobile applications. Numerous studies have shown the importance of low latency ... -
Geographies of Urban Filth
(University of Waterloo, 2019-01-23)This thesis studies how our cultural understanding of dirt and cleanliness are bound to issues of class and race and how they are manifested within urban and spatial design. Boundaries are formed between clean and dirty, ... -
Geologic Control: Studies on the Colonial Afterlife of Limestone in Montreal, Quebec Through Artifact
