The genus Solidago L. (Astereae, Asteraceae) in South America and related taxa in North America
(University of Waterloo, 2009-05-14)The goldenrod genus Solidago L. is one of the larger genera in the flowering plant family Asteraceae. The genus is primarily North American and was recently revised in Flora of North America. In contrast, Solidago in South ... -
Geochemical and microbiological characterization of effluent and pore water from low-sulfide content waste rock
(University of Waterloo, 2013-04-22)Laboratory and field studies were completed to characterize the geochemistry and microbiology of drainage emanating from low-S content waste-rock test piles at the Diavik Diamond Mine (Diavik) from 2007 through 2010. The ... -
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. ... -
Geology, geochemistry and Cr-Ni-Cu-PGE mineralization of the Bird River sill: Evidence for a multiple intrusion model
(University of Waterloo, 2008-05-09)The Bird River sill (BRS) is composed of layered mafic-ultramafic intrusive bodies which intruded the Bird River greenstone belt in southeastern Manitoba. Layered intrusions, such as those that collectively make-up the ... -
Geometry of Quantum States from Symmetric Informationally Complete Probabilities
(University of Waterloo, 2013-08-06)It is usually taken for granted that the natural mathematical framework for quantum mechanics is the theory of Hilbert spaces, where pure states of a quantum system correspond to complex vectors of unit length. These vectors ... -
Geophysical response to simulated methane migration in groundwater based on a controlled injection experiment in a sandy unconfined aquifer
(Elsevier, 2019-09)Geophysical methods have the capacity to detect and characterize gas-phase dynamics in groundwater. Suitable methods can be deployed at surface or within boreholes depending on the required depth of investigation, ... -
Geotechnics and hydrology of landslides in Thompson River Valley, near Ashcroft, British Columbia
(University of Waterloo, 2008-08-21)Landslides in Pleistocene sediments along the Thompson River, south of Ashcroft, British Columbia have been known since before the Canadian Pacific (CP) railway was built through the valley in the 1880s. The Canadian ... -
Gibberellin Biosynthesis in Bradyrhizobium japonicum USDA110
(University of Waterloo, 2014-10-28)Biosynthesis of gibberellin (GA) by bacteria has been studied for nearly 50 years. Early on, bacterial culture extracts were analyzed for the presence of bioactive compounds, thought to be gibberellins. In the 1980s, ... -
Gibbs Energy Dynamic Yield Method (GEDYM): Predicting microbial growth yields under energy-limiting conditions
(Elsevier, 2018-11-15)Biomass-explicit biogeochemical models assign microbial growth yields (Y) using values measured in the laboratory or predicted using thermodynamics-based methods. However, Y values are rarely measured under the low energy ... -
Glacial Dispersion at the Canadian Malartic Gold Deposit
(University of Waterloo, 2024-04-19)A novel drift prospecting approach detected components from previously established bedrock footprints at the world-class Canadian Malartic gold deposit within the site’s surrounding Quaternary sediments. The measured glacial ... -
Glassy States in Asymmetric Mixtures of Soft and Hard Colloids
(APS Physics, 2013-11-14)By employing rheological experiments, mode coupling theory, and computer simulations based on realistic coarse-grained models, we investigate the effects of small, hard colloids on the glassy states formed by large, soft ... -
