Generation of Short Laser Pulses by Using Hollow Fibre and Chirped Mirror Compressor System
(University of Waterloo, 2017-10-23)A FEMTOLASERS hollow core silicon fibre of length 1 m and 250μm inner diameter was set up in the lab in Waterloo with the purpose of generating sub 10fs pulses for Coulomb Explosion Imaging (CEI). The input laser was a new ... -
Generational Effects of Bisphenol A on Growth and Stress Performance in Rainbow Trout
(University of Waterloo, 2014-06-25)The aquatic environment is severely impacted by xenobiotics that are released due to anthropogenic activities, threatening ecosystem health. Some of these contaminants accumulate in lipophilic fish tissues and are maternally ... -
Genesis of a giant Paleoproterozoic strata-bound magnesite deposit: Constraints from Mg isotopes
(Elsevier, 2016-08-01)Giant strata-bound magnesite deposits are absent in modern and most Phanerozoic sedimentary environments but occur predominantly in Precambrian strata. These deposits may have formed directly through precipitation of evolved ... -
The Genetic Analysis of Autophagy-Dependent Caspase Activation in Drosophila melanogaster
(University of Waterloo, 2009-10-23)During Drosophila melanogaster pupation, groups of undifferentiated adult cells proliferate and undergo regulated cell shape changes, while larval tissues are eliminated by programmed cell death (PCD). PCD is most commonly ... -
Genome analysis reveals unexpected absence of oxygen metabolic capacity in helminths
(University of Waterloo, 2022-07-06)Oxygen metabolism in parasitic helminths differs significantly from that of most aerobic eukaryotes, as these organisms must be able to switch between aerobic and anaerobic metabolisms depending on their life-cycle stage. ... -
A genomic study of the invasive red alga Bangia atropurpurea (Mertens ex Roth) C. Agardh
(University of Waterloo, 2022-04-13)The phylum Rhodophyta comprises the red algae, which are morphologically diverse organisms present in marine and freshwater environments. The red algae order, Bangiales, is an ancient lineage and molecular studies have ... -
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
