Mathematical modeling of HIV-1 therapeutic initiatives: shock and kill strategy in the brain and the natural control of the virus in the plasma
DownloadSpring 2024
This thesis is based on four main studies. The first two studies present a detailed methodology for completing dynamical system parameter estimation using Bayesian inference. The next two studies are about using this methodology to investigate critical human immunodeficiency virus-1 therapeutic...

Quantification of Coarse TiN-rich Precipitates in High Ti Microalloyed Steels Using EMPA Mapping and SEM/EDX
DownloadSpring 2024
Microalloyed steels are high strength steels with low alloying additions of Ti, Nb, and V. These microalloying elements form carbonitride precipitates during thermomechanical controlled processing (TMCP), which enhance the mechanical properties of steel. TiN is one of the first precipitates to...

Improving Utilization of Ir-Based Catalyst Layers in Proton Exchange Membrane Water Electrolyzers
DownloadSpring 2024
In order to store large quantities of intermittent renewable energy, proton exchange membrane water electrolyzers (PEMWE) can be used to produce hydrogen which can then be used in a fuel cells to retrieve the energy. One limitation of PEMWE is that the catalysts used, commonly platinum and...

Tears at the Heart of Things: Moral Distress Among Principals of Canadian-Accredited Schools in China
DownloadSpring 2024
Moral distress arises when a person is aware of a moral problem, acknowledges a moral responsibility to act, yet is constrained from following a course of action congruent with their own moral judgement (Nathaniel, 2006; Jameton, 1984). Being hindered from doing what one believes to be morally...

Ichnology and geochemistry: an integrated approach to early marine diagenesis in the Arabian Gulf
DownloadSpring 2024
Neoichnological studies in carbonate-dominated tropical latitudes are sparse. Moreso, the coupling of diagenetic research utilizing ichnology has been largely limited to ancient successions. This thesis combines geochemical analyses with modern ichnological observations to better understand the...
