Wettability Alteration by Chemical Agents at Elevated Temperatures and Pressures to Improve Heavy-Oil Recovery
DownloadFall 2017
The thermal method is the primary method used to improve the recovery from reservoirs with heavy or extra-heavy oil. However, the efficiency and economic costliness of the traditional thermal process are limited by the unfavorable interfacial properties of heavy oil/water (steam)/rock system....

Fall 2014
Abstract Abundant hydrocarbon resources in low-permeability formations are now accessible due to technological advances in multi-lateral horizontal drilling and multi-stage hydraulic fracturing operations. The recovery of hydrocarbons is enhanced by the creation of extensive fracture networks....

Spring 2018
Superhydrophobic interfaces, due to their unique water repellent and self-cleaning properties, are attracting a wide-spread interest for implementation in a variety of applications, including self-assembly based fabrication methods, nano/microfluidics, and solar energy harvesting. To facilitate...

Spring 2013
This thesis is concerned with the effect of mechanical wear on superhydrophobic surfaces (SHS). This work, for the first time, systematically details the simultaneous surface topography and wetting behavior changes upon abrasion of SHS. The process of physical abrasion was also simulated on the...

What are people doing in our parks? Understanding, comparing, and predicting the low-impact camping practices of Canadian Provincial Park over-night visitors
DownloadFall 2016
Canadian provincial parks attract millions of visitors every year; and while these visitors come to parks to enjoy their natural beauty, experience cultural and natural heritage, and participate in outdoor recreation they are also simultaneously having a negative impact on the park ecosystems....

What are the Experiences of Family Caregivers Participating in an Arts-based (Collage) Intervention? A Secondary Analysis
DownloadFall 2017
Current social and demographic trends include a shift toward an elderly population, an increase in life expectancy and an increase in chronic disease, all of which contribute to increased care needs. Family members are depended upon to take on the caregiving role for those with physical or...

What can Foucault tell us about Fun in Sport? A Foucauldian Critical Examination of the Discursive Production and Deployment of Fun within Varsity Coaching Contexts
DownloadFall 2014
Fun is a concept of growing importance in sport and in sport coaching research (e.g., Bigelow et al. 2001; Mastrich, 2002; Small, 2002; Smoll et al., 1988; Thompson, 1997; 2003). Fun, and especially fun in sport, is generally understood not only as being unproblematic but also as being inherently...
