Fall 2010
A study was conducted to evaluate the properties and processes influencing the rate and magnitude of volume decrease and strength gain for oil sand fine tailings resulting from a change in bitumen extraction process (caustic versus non-caustic) and the effect of adding a coagulant to caustic fine...

Variation in xylem structure and function has been extensively studied across different species with a wide taxonomic, geographical and ecological coverage. In contrast, our understanding of how xylem of a single species can adjust to different growing conditions remains limited. In this thesis,...

Studies on frost heave indicate that significant frost heave observed in the field or laboratory is attributed to ice lens formation associated with water migration to the freezing front and the segregational ice that develops. Hence frost heave prediction models require ice lens initiation...

Sodium hydroxide (NaOH) is used as a chemical additive to enhance bitumen recovery from oil sands by surface-mining extraction process. The addition of NaOH adjusts the pH of the slurry water to pH ~8.5 (approximate pH of process water). The change in pH of oil sand slurry affects the process...
