Characterizing Net Life Cycle Greenhouse Gas Emissions and Environmental Performance of Organic Field Crops in Ontario and Quebec
(University of Waterloo, 2023-01-20)Food production systems are at the heart of one of humankind’s greatest challenges – meeting the nutritional demands of a population expected to reach 10 billion by 2050 while limiting contributions to environmental ... -
Characterizing Noise in Quantum Systems
(University of Waterloo, 2012-07-26)In practice, quantum systems are not completely isolated from their environment and the resulting system-environment interaction can lead to information leakage from the system. As a result, if a quantum system is to be ... -
Characterizing poly-substance use and its associations with anxiety and depression among a sample of Canadian high school students
(University of Waterloo, 2022-01-05)In any given year, one in five Canadians experience mental illness. The majority of mental illnesses originate in adolescence or young adulthood. Many complex factors can contribute to this, including substance use. However, ... -
Characterizing Polymers with Complex Architecture using Pyrene Excimer Fluorescence
(University of Waterloo, 2021-09-29)This thesis combines two different models, namely the model free analysis (MFA) and the fluorescence blob model (FBM), that were used to study the conformation and internal dynamics of two highly branched macromolecules, ... -
Characterizing sediment transport and stability in remote river systems
(University of Waterloo, 2020-05-26)Canada is a large country with vast networks of linear infrastructure, such as roads and pipelines, that unavoidably intersect with waterways. Engineers must be able to characterize geomorphologic processes and channel ... -
Characterizing Sex Differences in Lipid Metabolism during an Acute, 30-Minute Bout of Moderate- Intensity Continuous (MIC) Exercise
(University of Waterloo, 2021-01-05)INTRODUCTION: Increased intramyocellular lipid (IMCL) size and storage in the subsarcolemmal region of the myocyte are associated with insulin resistance (IR) and the development of type 2 diabetes (T2D). Women have a ... -
Characterizing Sex Differences in Skeletal Muscle Anaerobic Metabolism during an Acute Bout of High Intensity Interval Exercise
(University of Waterloo, 2020-09-03)INTRODUCTION: Exercise is known to improve insulin sensitivity (IS); however, its effectiveness may be absent or blunted in women, particularly following high intensity interval (HII) training. Sex differences in anaerobic ... -
Characterizing Single Photon Emission From Quantum Dots in Nanowires
(University of Waterloo, 2019-05-28)Bright sources of highly indistinguishable single photons are desirable for diverse applications in quantum technology, including quantum cryptographic protocols, information processing, and metrology. The most common ... -
Characterizing site-specific body composition of older adults and their associations with strength, functional capacity, and metabolic health
(University of Waterloo, 2021-06-03)Background: Ageing is associated with skeletal muscle atrophy and increased intramuscular adipose tissue. Emerging evidence indicates that specific muscle groups may be largely responsible for the ageing-related degradation ... -
Characterizing Spatial and Temporal Variations in Nutrient and CO2 Dynamics Within and Across Peatlands in the Western Boreal Plain, Canada
(University of Waterloo, 2015-02-10)Peatlands are found extensively throughout the Western Boreal Plain, a region under pressure due to persistent drought conditions and industrial development (especially oil and gas, and oil sands development). Our ability ... -
Characterizing the Associations and Roles of DDK and Mcm2-7 DNA Replication Proteins in Saccharomyces Cerevisiae
(University of Waterloo, 2014-05-21)The essential cell cycle kinase Dbf4/Cdc7 (DDK) triggers DNA replication through phosphorylation of the Mcm2-7 helicase at replication origins. Prior work has implicated various Mcm2-7 subunits as targets of DDK, however ... -
Characterizing the Biomechanical Exposures Associated with Common and High Demand Personal Support Worker Tasks
(University of Waterloo, 2023-08-31)Background: The physical demands that personal support workers (PSWs) are exposed to are increasing as our population ages and our society is increasingly shifting to at-home care, resulting in increases in workload ... -
Characterizing the Constitutive Behaviour and Austenite Decomposition of an 1,800 MPa Press Hardenable Boron Steel
(University of Waterloo, 2024-02-02)The mechanical behaviour of a new 1,800 MPa strength grade of Al-Si coated, 37MnB5 press-hardenable steel, designated PHS 1800, was investigated under hot stamping conditions. Prior to mechanical testing, a novel heat ... -
Characterizing the deformation response of a unidirectional non-crimp fabric for the development of computational draping simulation models
(University of Waterloo, 2020-06-01)In several countries around the world, including Canada, government incentives have been put in place to improve the fuel efficiency of vehicles and reduce CO2 emissions. Improvements in composites manufacturing technology, ... -
Characterizing the Dimer Interface and Thermal Unfolding of Reduced, Zinc Bound Superoxide Dismutase-1
(University of Waterloo, 2018-04-30)Superoxide dismutase 1 (SOD1) is a ubiquitously expressed metalloenzyme that reduces oxidative stress in cells by catalyzing the dismutation of superoxide radicals. Mutations in the gene encoding for SOD1 have been linked ... -
Characterizing the Dynamics of Otto Glacier, Ellesmere Island, Canadian High Arctic: 1992-2020
(University of Waterloo, 2023-09-22)The mass loss observed from glaciers in the Canadian Arctic is unprecedented over recent decades (Hugonnet et al., 2021) and is the third largest contributor to global sea level rise (Derksen et al., 2019). One way in which ... -
Characterizing the dynamics of vestibular reflex gain modulation using balance-relevant sensory conflict
(University of Waterloo, 2023-09-21)Electrical vestibular stimulation (EVS) can be used to evoke reflexive body sways as a probe of vestibular control of balance. However, EVS introduces sensory conflict by decoupling vestibular input from actual body motion, ... -
