Corundum formation by metasomatic reactions in Archean metapelite, SW Greenland: Exploration vectors for ruby deposits within high-grade greenstone belts
(Elsevier, 2018-05-01)Corundum (ruby-sapphire) is known to have formed in situ within Archean metamorphic rocks at several localities in the North Atlantic Craton of Greenland. Here we present two case studies for such occurrences: (1) Maniitsoq ... -
Cosmic Acceleration As Quantum Gravity Phenomenology
(University of Waterloo, 2010-09-22)The discovery of cosmic acceleration has prompted the need for a new understanding of cosmology. The presence of this acceleration is often described as the dark energy problem or the Lambda problem.The simplest explanation ... -
Cosmic Atoms: from Causal Sets to Clusters
(University of Waterloo, 2014-08-19)This thesis is a collection of works which seek to address certain aspects of the following puzzles: quantum gravity, initial conditions of the universe, the cosmological constant problem, and baryonic processes in clusters ... -
Cosmological beam plasma instabilities
(University of Waterloo, 2017-08-24)Blazars are the main source of extragalactic very high energy gamma-rays. These gamma rays annihilate on the extragalactic background light, producing electron-positron pair beams with TeV energies. The pair beams are very ... -
Cosmological Results and Implications in Effective DGP
(University of Waterloo, 2009-01-26)We study a simple extension of the decoupling limit of boundary effctive actions for the Dvali-Gabadadze-Porrati model, by covariantizing the π lagrangian and coupling to gravity in the usual way. This extension agrees ... -
Cosmological Tests of Causal Set Phenomenology
(University of Waterloo, 2017-09-20)Causal Set Theory is an approach to Quantum Gravity that postulates that the fundamental structure of a spacetime manifold is a Lorentz Invariant discrete structure endowed with a causal order from which the geometry and ... -
Cosmology with Cluster Structural Properties
(University of Waterloo, 2023-06-23)Galaxy clusters are massive objects composed of hundreds or thousands of galaxies, hot gas and an extended dark matter (DM) halo. They are the largest gravitationally bound structures in the Universe. As such, they result ... -
Cost-effectiveness of Chimeric Antigen Receptor T-cell Therapy for Treating Large B-cell Lymphoma Patients in Canada
(University of Waterloo, 2020-01-21)Background/Aim: Chimeric antigen receptor (CAR) T-cell therapy is a novel cell therapy for treating hematological cancers including multiply relapsed large B-cell lymphoma in adults. Although for some patients it can ... -
Coupling of two natural complex systems: earthquake-triggered landslides
(University of Waterloo, 2012-04-30)This thesis contains two main parts. The first part presents a database compiling 137 landslide-triggering earthquakes (LTEs) worldwide, with magnitudes greater than the minimum observed threshold for causing landslides ... -
Coupling reactive transport and travel time modeling at the watershed scale
(University of Waterloo, 2018-09-25)Nonpoint source pollution poses the greatest threat to water quality in developed countries. Modeling this type of pollution is a challenge for reactive transport models because of the change in scale: moving from a local ... -
Coupling solid phase microextraction to complementary separation platforms for metabotyping of E. coli metabolome in response to natural antibacterial agents
(Springer, 2016-11-02)Introduction Essential oils are known to possess antimicrobial activity; thus, their use has played an important role over the years in medicine and for food preservation purposes. Objective The effect of clove oil and its ... -
Covalent linking DNA to graphene oxide and its comparison with physisorbed probes for Hg2+ detection
(Elsevier, 2016-05-15)Graphene oxide (GO) has attracted extensive research interest as a platform for DNA adsorption and biosensor development. While most researchers use simple physisorption of fluorescently labeled DNA, covalent sensors are ... -
Cr3+ Binding to DNA Backbone Phosphate and Bases: Slow Ligand Exchange Rates and Metal Hydrolysis
(American Chemical Society, 2017-06-07)The interaction between chromium ions and DNA is of great interest in inorganic chemistry, toxicology, and analytical chemistry. Most previous studies focused on in situ reduction of Cr(VI), producing Cr3+ for DNA binding. ... -
Creating and probing laser-cooled atomic ensembles inside a hollow-core optical fibre
(University of Waterloo, 2024-01-26)A laser-cooled atomic ensemble confined inside a hollow-core optical fiber offers a unique platform for enhanced light-matter interactions and their applications. At the same time, transferring a cloud of laser-cooled ... -
A critical review of solid phase microextraction for analysis of water samples
(Elsevier, 2016-12-01)The review summarizes applications of solid phase microextraction (SPME) for water sample analysis. Official methods and standards of SPME in water research and inter-laboratory validation are discussed. A comparison of ... -
