Bitumen mining and upgrading operations in the Athabasca Bituminous Sands Region (ABSR) may lead to increased concentrations of trace elements in the surrounding environment. Elevated concentrations of potentially toxic trace elements could pose a risk to local indigenous communities through the...

Steam assisted gravity drainage (SAGD) method is the main oil extraction method in Alberta that produces a huge volume of waste water. This thesis is focused on investigating the viability of membrane processes, as emerging water treatment technologies, for treatment of SAGD produced water. Three...

Adhesion of frozen granular materials on solid surfaces creates various problems for surface cleaning, reduces the carrying capacity of vehicles, and increases energy consumption for inland transportation. Here in the first part of this thesis, water content demonstrates to determine the adhesion...

The degree to which predator and prey distributions overlap in space influences the probability of encounters between predator and prey, kills of prey, and consequently, how each species’ abundance varies in time and in space. Predator and prey attempt to increase or decrease overlap respectively...
