Application of Deuterium Isotope Effects on NMR Parameters as a Method of Intramolecular Hydrogen Bond Characterization in Enolic Forms of 1,3-diketones in the Solid State
DownloadFall 2022
The application of deuterium isotope effects on 13C NMR chemical shifts to study the nature of intramolecular hydrogen bonding in the enolic forms of two 1,3-diketones, tetraacetylethane (TAE) and avobenzone, in the solid state is reported. Carbon-13 NMR spectra of natural abundance TAE and...

Forest Tree Population Response to Climate Variability and Climate Change: Implications for Reforestation
DownloadFall 2022
This dissertation aims to quantify the sensitivity and adaptive capacity of forest tree species to climate change in Canada and North America, with applications of guiding sustainable forest management through case studies focusing on Alberta. The general idea is that management interventions...

The role of Receptor Interacting Serine/Threonine Kinase 2 (RIPK2) in inflammatory breast cancer (IBC)
DownloadFall 2022
Inflammatory breast cancer (IBC) is a rare but aggressive type of breast cancer characterized by early and rapid metastasis leading to poor clinical outcomes. The tumor microenvironment (TME), including immune cells, fibroblasts and endothelial cells, has emerged as a major regulator of IBC...

Nuanced Effects of Decision Effort on Decision Confidence in Matters of Quality versus Matters of Taste
DownloadSpring 2022
Consumers are largely considered cognitive misers because of their general aversion toward exerting mental effort in decision making. Prior research suggests that engaging in effortful decision tasks tends to undermine consumers’ decision confidence by increasing metacognitive difficulty. In the...
