2012 — Exploring the Way Servant Leaders Foster Employee Development: A Qualitative Study of Servant Leaders in Non-Profit OrganizationsAbstract
The literature on servant leadership in third sector organizations is in dire need of further research for documenting the developmental effects of servant leadership on employees in non-profit organizations (Schneider & George, 2011). The purpose of this qualitative phenomenological study was to explore how servant leaders in non-profit organizations perceived their role cultivating their employees’ personal and professional development. The population under investigation constituted six Saskatchewan executive directors and managers, who worked for non-profit organizations, had more than 10 years experience in leadership roles, and identified as servant leaders within that timeframe. A modified van Kaam method utilized a servant … Read more

2012 — Modeling and Measuring Association for Ordinal DataAbstract
We propose the modified Pearson goodness-of-fit statistic and consider it in the cumulative contingency tables. For the non-cumulative tables, we provide the scoring systems and the variance minimization correction term to Pearson goodness-of-fit statistic. We also put forward the average of individual odds ratios as the common odds ratio and modify the Mantel-Haenszel estimator of common odds ratio in a K x K ordinal contingency table where the category numbers of the variables are the same. The M[superscript2] statistic with scoring systems is also introduced. From the simulation results, we figure out that the chi-square statistics do not work except … Read more

2012 — “That’s the Life of a Gangster”: analyzing the media representations of Daniel Wolfe.Abstract
Daniel Wolfe has been represented by the news media as one of Saskatchewan and Manitoba’s most “notorious gang members.”1 Wolfe first made headlines at the age of 31 after he instigated a fatal home invasion in the rural community of Fort Qu’Appelle, northeast of Regina.2 Later that year, while on remand at the Regina jail, Wolfe and five other Aboriginal inmates staged an elaborate break-out which received extensive national media coverage.3 Two years later Wolfe was killed in prison. His death, although tragic, was regarded by media and experts as an “obvious conclusion” to a gangster’s story.4 Through an interdisciplinary … Read more

2012 — Corrosion Evaluation for Absorption - Based CO2 Capture Process Using Single and Blended AminesAbstract
One of the major problems associated with the amine-based carbon dioxide (CO2) capture process is corrosion of process components, which results in unexpected downtime, production loss, and even major fatalities. Most of the published corrosion literature is on conventional monoethanolamine (MEA) solvent, and there have been very few corrosion studies conducted on other single amines like methyldiethanolamine (MDEA), diethanolamine (DEA), 2-amino-2-methyl-1-propanol (AMP), and some blended amines. Although there has been extensive research conducted on the kinetics of concentrated piperazine (PZ) as an attractive solvent for the CO2 absorption process, no corrosion studies have been conducted for this solvent. This work … Read more

2012 — Inquiring into inquiry learning in secondary science education.Abstract
This research study investigates the creation, use, and effectiveness of inquiry lab activities in a secondary science classroom. The study begins by reflecting on what leads the teacher-researcher to convert traditional, step-bystep lab activities into student-centered inquiries by turning them inside-out and gains momentum as positive student-participant feedback is obtained. Using the reflective practice and narrative inquiry influenced approaches as the central research tools teacher-researcher and student-participants can provide one another with feedback into their experiences with both traditional and inquiry approaches to lab activities. The two-way communication between teacher-researcher and student-participants is illustrated within the thesis text itself as … Read more

2012 — An Empirical Study of Health Professionals' Beliefs about Personhood in Dementia and Their Influence on Intended Patient CareAbstract
Three studies were conducted to measure health providers' beliefs about the personhood of long-term care residents with dementia, and the influence of these beliefs on health providers' intended actions toward patients in the long-term care contexts. In Study I, a Likert-format measure of health providers' beliefs about the personhood of long-term care residents with dementia (the Personhood in Dementia Questionnaire) was created after reviewing relevant literature and consulting with health providers. In Study II, this questionnaire was administered to a pilot sample of nurses and continuing care assistants. Psychometric analysis and subject matter expert review were used to reduce the … Read more

2012 — Reducing Provincial Drug Plan Costs Through Regional Pooled-Purchasing AgreementsAbstract
Canada’s provincial health ministries are facing rising provincial drug plan costs that can be attributed to rising medication costs and increasing drug plan claims. Provinces currently employ a collection of policy tools that have not proven to be effective in reducing the cost of these essential programs. Current policy tools are generally designed and implemented unilaterally and are not conducive to inter-provincial collaboration. The result is that small provinces are hampered in their ability to lower drug costs as manufacturers will first attempt to set price levels in larger provinces. A new policy tool is needed that will enable both … Read more

2012 — Geotechnical Investigation of Uranium TailingsAbstract
With the increasing uranium demand for power generation, the mining industry is considering expansion of existing facilities. The management of tailings, generated as a by-product of ore beneficiation, in containment structures is particularly important to minimize the environmental footprint. A clear understanding of slurry behavior is required at the onset of deposition in the containment facility. The main purpose of this research was to understand the geotechnical behaviour (index properties, segregation, dewatering) of uranium tailings under field and laboratory conditions. The historical data of tailings characteristics in the Deilmann Tailings Management Facility (DTMF) at Key Lake, Saskatchewan, were analyzed to … Read more

2012 — Engineering Properties of Badlands in Semi-Arid RegionsAbstract
Geology and seasonal weather variations govern the engineering properties of Avonlea badlands in Saskatchewan, Canada. Three surface sediments exhibiting distinct lithologic variations were found: a steep and fissured sandstone; a mildly-sloped and popcorntextured mudrock; and a flat and eroded pediment. The variation in material composition and the water availability conditions increase the saturation-desaturation cycle that ultimately affect material behavior. The fines content increased from dry to wet state with 17% to 33% for sandstone, 4% to 98% for mudrock, and 21% to 42% for pediment. The water adsorption capacity was found to be highest for mudrock (wl = 96% and … Read more

2012 — Kinetic Study of Catalytic Partial Oxidation of Synthetic Diesel for Hydrogen ProductionAbstract
The focus of this research is to study the kinetics of the catalytic partial oxidation (CPOX) of synthetic diesel (SD) for hydrogen production. The kinetic experiments were done in a packed bed tubular reactor (PBTR) over a 5wt.%Ni/Ce[subscript 0.5Z]r[subscript 0.33]Ca0.085Y[subscript 0.085] (5N/CZCaY) catalyst prepared by a surfactant-assisted route. The SD is composed of 75 vol.% saturated hydrocarbons and 25 vol.% aromatic hydrocarbons, with an average chemical formula resembling commercial diesel C[subscript 12.87]H[subscript 24.81]. The kinetic experiments were conducted at atmospheric pressure, in the temperature range of 1123-1223K (850- 950 degrees C), with oxygen/synthetic diesel (O2/SD) ratio in the range of … Read more

2012 — Identification, distribution and evolution of three type III secretion systems and their effectors in the pathogen, Pantoea stewartii sp. stewartii DC283Abstract
The type III secretion system (T3SS) is an extracellular appendage used primarily by bacteria for pathogenesis in both plants and animals, including humans. Related to the bacterial flagellum, this nanomachine uses an extracellular pilus to actively transport effector proteins from Gram-negative bacteria directly into the host cell to cause disease. One genus that uses the T3SS is Pantoea, which comprises several well-studied plant pathogenic species, as well as opportunistic human pathogenic species. Three T3SSs were identified in a diverse collection of Pantoea representing plant, clinical and environmental samples: a plant-specific T3SS Hrc 1, and two animal-specific T3SSs, SPI-1 and SPI-2. … Read more

2012 — Recovered Accounts of Saskatchewan Adult Education: A Governance MomentAbstract
While a good deal is known about the history and governance structures within the Saskatchewan K-12 system, very little is known about the adult education and training sector. Faris (Cassidy & Faris, 1987) indicates that, given the magnitude and importance of the sector, the low status and remarkably little attention paid to the field of adult education is puzzling. Accordingly, the purpose of this study is to understand and synthesize the lived-experiences of key decision-makers in order to make recommendations to improve the governance of the Saskatchewan adult education and training sector. Moreover, it is disturbing to find that the … Read more

2012 — The measurement of stride-to-stride fluctuations in the gait of young and older adults using a body-fixed, tri-axial accelerometer.Abstract
Falls represent one of the most significant health problems that affect older adults. Having the ability to accurately analyze and screen the gait of individuals who may be at risk of falling is an essential step to improving their health. Research has shown that there are numerous age-related changes in gait and that these changes may increase the risk of falling. More important than mean spatiotemporal parameters of gait, are the stride-to-stride fluctuations inherent in these measures. Both gait variability (i.e., the standard deviation of spatiotemporal gait parameters) and fractal dynamics (i.e., the patterning of fluctuations observed over a larger … Read more

2012 — Stratigraphic architecture and facies analysis of the Lower Cretaceous Dina Member of the Mannville Group in Northwest Saskatchewan.Abstract
The Dina Member in northwest Saskatchewan was deposited unconformably on top of the underlying Devonian Elk Point Group with the thickest Dina sandstones residing within paleo-topographic lows on the unconformity surface. The Dina Member was extensively eroded by Pleistocene glacial processes and is unconformably overlain by Pleistocene glacial tills. Analysis of 83 stratigraphic test hole drill cores and 255 geophysical well log suites has revealed 8 recurring facies and 5 facies associations. The facies are comprised of siliciclastic sediments, including sandstones, siltstones, mudstones and in rare instances, coal. These facies are predominantly non-marine in origin, including fluvial sediments and associated … Read more

2012 — Cartographic visualization of Saskatchewan’s population using dasymetric mapping.Abstract
Maps of population density are commonly displayed using the choropleth method. Although choropleth maps are popular in mapping population density, strictly speaking, they are often incorrect due to non-conforming boundaries of populated places and administrative areas. This thesis looks at the dasymetric concept as an alternative to the choropleth map and investigates how it can be applied to display Saskatchewan’s population. Using ancillary data, the dasymetric method can redistribute statistical population data exclusively to areas identified as populated. As a basis for the research, 12 existing dasymetric methods were reviewed and evaluated for their applicability to Saskatchewan. Based on this … Read more

2012 — The Fundamental Modules of the Classical Lie AlgebrasAbstract
The main objective of this Thesis is the construction of the fundamental modules of the classical Lie algebras. Weyl’s Theorem shows that if L is a semisimple Lie algebra, then any finite dimensional L−module is a direct sum of irreducible L−modules. Since the classical algebras are semisimple, we just need the irreducible modules in order to obtain the others. On the other hand, the fundamental modules give us every irreducible L− module and, therefore, every finite dimensional L−module. Read more

2012 — Applicability of Hot Water-Alternate- CO2 Flooding in Heavy Oil Reservoirs,Abstract
Increasing world energy demand and depletion of conventional oil reservoirs is forcing scientists and industry to seek new – unconventional – sources of hydrocarbons. While conventional crude oil accounts for 1.0 trillion barrels, the amount of heavy oil and bitumen is five times larger – 5.4 trillion barrels (Herron 2006). A huge part of these extremely high and difficult to extract hydrocarbons is deposited in Canada. In such heavy oil reservoirs, waterflooding has proved to be inefficient due to unfavourable mobility ratio between displacing and displaced fluids that leads to low sweep efficiency and early breakthrough. This results in high … Read more

2012 — National Security Crises and the Expanding American PresidencyAbstract
The Constitution is meant to protect the rights of American citizens, while providing the United States with a strong and responsible government. During times of crisis, the executive branch of the government has often expanded its authority claiming that it requires extra powers to defend the nation. After the September 11 terrorist attacks, the George W. Bush administration expanded executive power and Congress did not object. For example, Congress passed the USA PATRIOT Act and President Bush signed it into law on October 26, 2001, allowing law enforcement agencies to obtain records and conduct surveillance on anyone suspected of terrorism-related … Read more

2012 — Hydroclimatic Scenarios Using Dendroclimatic, Historical and GCM-Based Records Over the Northwestern Great PlainsAbstract
Historically, the Canadian Prairies have been highly susceptible to extreme drought and pluvial events, resulting in economic hardship. There are strong associations between large-scale circulation patterns (i.e. teleconnections), such as the low frequency Pacific Decadal Oscillation (PDO), and higher frequency El Niño-Southern Oscillation (ENSO) and North Atlantic Oscillation/Arctic Oscillation (NAO/AO), and the interannual to multi-decadal hydroclimatic variations over western North American. Archives of the longest instrumental period of record (~100 to 150 years) are unlikely to capture the full range of hydroclimatic variability (50-70 years) or enable full assessment of the links between the large-scale circulation patterns and the regional … Read more

2012 — Heavy Gas Cherenkov Detector Construction for Hall C at Thomas Jefferson National Accelerator FacilityAbstract
The Thomas Jefferson National Accelerator Facility (JLab) has undertaken the 12 GeV Upgrade to double the accelerating energy of its electron beam. This attracts many interesting proposals to probe the quark-gluon nature of nuclear matter at higher energy, therefore a new set of equipment is required. Experimental Hall C of JLab has planned to construct a new Super High Momentum Spectrometer (SHMS) to replace the existing Short Orbit Spectrometer (SOS). The University of Regina is assigned to construct the Heavy Gas Cˇ erenkov (HGC) Detector as part of the SHMS focal plane detectors. This detector will be used as critical … Read more

2012 — Coupling of Hydrocarbon Solvents of Hot Water for Enhanced Heavy Oil RecoveryAbstract
Abundant heavy oil reserves and increasing demands for energy have encouraged more and more interest in the exploitation of heavy oil. The recovery of heavy oil is challenging due to its high viscosity. The thermal recovery process has been widely used to reduce the viscosity and increase the mobility of heavy oil, namely cyclic steam stimulation (CSS), in situ combustion (ISC) and steam-assisted gravity drainage (SAGD). Among them, SAGD is the most popular method for recovering heavy oil. However, SAGD usually causes large heat loss and requires a huge amount of water and extensive surface facilities. Also it becomes inefficient … Read more

2012 — Liberal Value Pluralism: A Study of the Political Ideas of Michael IgnatieffAbstract
This thesis looks at the writings of Michael Ignatieff to try to answer whether the value pluralist philosophy he espouses is compatible with his doctrine of human rights. Value pluralism is a political and ethical philosophy first developed by Isaiah Berlin that believes the values we hold to be plural. This plurality of values is fundamentally irreducible or incommmensurable. In other words, there is no common measure by which we can reliably compare values. A further aspect of value pluralism is that values change and people value different things. That is, values are social and historical. And since values are … Read more

2012 — Structural Style and Regional Comparison of the Paleoproterozoic Ketyet River Group in the Region North-Northwest of Baker Lake, NunavutAbstract
Archean to Paleoproterozoic rocks of the Rae Craton, Western Churchill Province, have been affected by polyphase deformation and metamorphism causing structural complexity and confusion regarding the age and affiliation of rock units. This study improves the stratigraphic and structural understanding of the Paleoproterozoic Ketyet River group and immediately subjacent Neoarchean rocks through detailed mapping of four areas north and west of Baker Lake: “Nipterk Lake”, “Ukalik Lake”, “Bar Lake” and Kiggavik, north of the uranium deposits. This improves knowledge of the basement rocks marginal to the late Paleoproterozoic Thelon Basin for unconformity-related uranium exploration. In 2010 and 2011, detailed mapping … Read more

2012 — Riddlehoard,Abstract
Riddlehoard is a collection of literary riddles inspired by the Old English Riddles of the Exeter Book. Riddlehoard describes objects that fall into three categories: objects accessible to the Anglo-Saxons, often because they pertain to the natural world; technological items largely unique to the twentieth and twenty-first centuries; and objects that self-consciously reflect on the act of riddling. Riddlehoard explores metaphor as interactive, mysterious, and playful and suggests an underlying absurdity to subjective human experience. Read more

2012 — Aboriginal Communities in Canada and HIV/Aids: The Voices Must Be HeardAbstract
The purpose of this research was to develop a theory grounded in the life experiences of Aboriginal community members in Canada that describes the ways in which they have been affected by HIV/AIDS. This theory has incorporated the effects of colonization within Aboriginal communities; although historical, effects of colonization have been linked by researchers to many health challenges confronting Aboriginal communities today. This thesis has reviewed the research evidence that suggests the higher prevalence and incidence of HIV/AIDS in Aboriginal communities has roots in historical colonization. The qualitative data collected provides experiential information documenting present-day experience of community members who … Read more

2012 — The Different Stories of Cree Woman, Daleen Kay Bosse (Muskego) and Dakota-Sioux Woman, Amber Tara-Lynn Redman: Understanding Their Disappearances and Murders through Media Re-Presentations and Family Members' NarrativesAbstract
Mainstream media re-presentations continue to position Aboriginal women as naturally hypersexual and immoral. This discursive strategy justifies, enables, and incites violence against Aboriginal women (Keating, 2006; LaRocque, 1990). In order to explore 1) how media outlets and agents can be responsive to family and friends of disappeared and murdered Aboriginal women and 2) how media re-presentations can effectively disrupt rather than re-produce white masculine and colonial hegemony, I conducted this thesis project with my co-researchers, Pauline Muskego and Gwenda Yuzicappi. Pauline is the mother of Daleen Kay Bosse (Muskego), a Cree woman from Onion Lake First Nation who disappeared in … Read more

2012 — Disability, Poverty and Welfare Policy: A Critical Disability Theory Analysis of Alberta’s Assured Income for the Severely Handicapped and Implications for SaskatchewanAbstract
Throughout modern history, people with disabilities have been socially and economically excluded and subject to intrusive, segregated services. The systemic exclusion of people with disabilities from mainstream society is a product of entrenched discrimination and the devaluing of their lives. The majority of people with disabilities are left with limited options, forcing them to rely on family members, charity and/or state programs to meet their financial and daily living needs. Disability activists have challenged the hegemonic belief that disability is an individual problem, labeling this the ‘individual pathology’ model of disability. They propose an alternative framework, ‘the social model’ which … Read more

2012 — The Gang Alternative: A Participant PerspectiveAbstract
Gang activity has increased in Regina over the past ten to fifteen years and has attracted considerable attention ostensibly contributing to higher crime rates and the abundance of drugs. As a result the public pressure on government to slow and reverse this proliferation of gangs is also growing. This is not a phenomenon unique to Regina yet the factors leading to gang proliferation in Regina among Aboriginal youth are vaguely understood at best. This results in an increased likelihood of faulty theorizing as to what are these risk factors and ineffective prevention and intervention programs. Through interviews with gang involved … Read more

2012 — Discovering the Meaning of the Experience of Interacting with Horses.Abstract
The literature on the human-animal bond is vast and has focused mainly on the bond between humans and their pets or small companion animals. However, within the literature, few studies exist that explore the human-horse interaction. Furthermore, studies that specifically examine the human partner’s perceived meaning of human-horse interactions are limited. Thus, the purpose of this qualitative, phenomenological study is to explore the lived experiences of adults who have interacted with horses. The intent of the study is to: 1) explore the essence or meaning of human-horse interactions, and 2) examine how this essence may contribute to a perceived sense … Read more

2012 — A New Approach to Face Recognition Based on Generalized Hough Transform and Local Image DescriptorsAbstract
In this thesis a new approach to face recognition is presented. Face recognition is one of the most proli c research elds and also one of the most demanding. It is in uenced not only by face-related attributes such as pose, position, scale, facial expression, accessories and physiognomy changes, but also by environmental factors like illumination, background, occluding objects, and, lastly, camera characteristics. The generalized Hough transform is improved so that it can nd the image region that best matches the template face image. Its reference point and hit rate are later used to discriminate between faces. The transform takes … Read more

2012 — PTSD Personality Subtypes in Women Exposed to Intimate Partner ViolenceAbstract
There is considerable research indicating that intimate partner violence (IPV) is a particularly detrimental traumatic experience that seriously compromises women’s physical, emotional, social, and mental health (Alexander, 2011; Campbell et al., 2002; Pico-Alfonso et al., 2006). A common reaction to IPV exposure is posttraumatic stress disorder (PTSD; Golding, 1999), which, though categorized singly, has a significantly heterogeneous presentation (Dickstein, Suvak, Litz, & Adler, 2010). Researchers have suggested underlying personality characteristics as potential reasons for differences in the expression of PTSD (Miller, Greif, & Smith, 2003). Specifically, a model with three personality subtypes (i.e., externalizing, internalizing, and simple) has been proposed … Read more

2012 — Studying Female Prostitution in Eighteenth-Century London: An Historiographical AnalysisAbstract
Prostitution has become an increasingly popular topic within the field of history, due largely to a growing interest in resurrecting the lives and voices of those who were never able to leave their own records. This has become known as social history, or “history from the bottom up,” in which individuals such as peasants, workers, women, and racial minorities take center focus. Subjects such as the prostitute are also ideal candidates for its study, as they were usually female and of extremely low social status. Though these individuals left very few records of their own, they were the subject of … Read more

2012 — The Structure of Operator Systems on Finite-Dimensional Hilbert SpacesAbstract
The purpose of this thesis is to describe in detail the structure of arbitrary operator systems S B(H), where H is assumed to be of finite dimension, using Arveson's non-commutative Choquet theory, and to determine the C* -envelope of S in certain special cases of interest. Arveson classifies these operator systems as either reduced or non-reduced, and we look at these classifications in detail. S is said to be reduced when its boundary ideal is {0} and non-reduced otherwise. We will give examples of 2-dimensional and 3-dimensional operator systems; show what Arveson's parametrization would be in such cases; and determine … Read more

2012 — Phylogenetic Analysis and Characterization of Plant, Environmental, and Clinical Strains of PantoeaAbstract
Multihost bacterial pathogens are an increasing concern as more bacterial species are found to cause harm to humans. Pantoea is recognized as a multihost pathogen, colonizing various hosts including plants, insects, and humans; however it is unknown how these strains are related, and the extent of their specific host ranges. Multilocus sequence analysis (MLSA) on six housekeeping genes of Pantoea revealed that some species are mixed, and contain plant, clinical, and environmental strains, while other species groups are composed of only plant or only clinical strains. Comparative growth assays in maize, onion, and fruit flies revealed that all plant, clinical, … Read more

2012 — Development of a mechanistic corrosion model for carbon steel in MEA-based CO2 absorption process.Abstract
This work developed a mechanistic corrosion model that can be used to predict corrosion rate of carbon steel in the carbon dioxide (CO2) absorption processes using aqueous solutions of monoethanolamine (MEA). The developed model enhances the capacity of the existing corrosion model developed by Veawab (2000) by incorporating three additional features including the presence of iron carbonate (FeCO3) on the metal surface and the presence of dissolved oxygen (O2) and heat-stable salts (HSSs) in the aqueous MEA solutions. The model was developed in Matlab, and comprises three sub-models, i.e. vapour-liquid equilibrium (VLE), species diffusion through a porous film, and electrode … Read more

2012 — The [Re]Construction of a Learner Self: A Phenomenological Study with Youth and Young Adults Postinvolvement in Criminal BehaviourAbstract
This phenomenological research study had as its focus the concept of „self as learner‟ as an internal, complex process of self-discovery within human experience. It sought to illuminate, firstly, the meanings youth and young adults who had engaged in criminal behaviour and been unsuccessful in the K – 12 system had drawn from being part of the schooling experience and their perception of „self as a learner‟; and secondly, the meanings they had drawn from their current experiences of being learners after involvement in the development of a portfolio that represented in a concrete way their own personal knowledge, skills … Read more

2012 — An Exploration of How Homelessness Affects Indigenous WomenAbstract
This thesis is an exploration of how homelessness affects Indigenous women. This study was conducted using an Indigenous research paradigm and executed from an Indigenous world view. Seven Indigenous women who were currently or had lived experiences with homelessness shared their stories and experiences with the researcher. Narrative inquiry using storytelling and thematic grouping were used. The medicine wheel concept was used to discuss the themes that arose from the stories. The storytellers where affected in all areas of the medicine wheel by their experiences with homelessness. Finding quality affordable housing, recovering from addictions, and practising cultural traditions were significant … Read more

2012 — Optical Transitions in Amorphous SemiconductorsAbstract
In this thesis, a quantitative analysis of the optical response of an amorphous semiconductor is presented. The entire analysis is cast within the framework of an empirical model for the valence band and conduction band density of states functions, that captures the basic features expected of these functions. A novel aspect of this analysis is the introduction of the density of localized valence band and conduction band electronic states and the establishment of a means of evaluating these densities from knowledge of the density of states functions coupled with the locations of the valence band and conduction band mobility edges. … Read more

2012 — Experimental Investigation of Viscosity Ratio Effect on Displacement Performance of Polymer Systems During Heavy Oil RecoveryAbstract
Heavy oil production during secondary recovery is often plagued by high producing water/oil ratios; this is a direct result of the unfavourable viscosity ratio that leads to viscous instability at the displacement front between the injected water and the more viscous oil. Polymer flooding has proven to be an exceptionally efficient enhanced oil recovery (EOR) technique that increases the stability of the displacing front, accelerating the pore displacement efficiency and improving the vertical and areal macroscale sweep efficiencies. This is especially important in heavy oil reservoirs, where recovery factors tend to be less than 10 % of original-oil-in-place (OOIP) The … Read more

2012 — Role of β-galactofuranose and β-glucan in Aspergillus nidulans hyphal cell wall ultrastructure and physical propertiesAbstract
The fungal cell wall is a first line of defence from the external environment or chemical treatments. Glucan, chitin and mannan are the main components of the Aspergillus nidulans hyphal cell wall. The sugar β-galactofuranose is a minor component of the cell wall and thought to be responsible for cross-linking of the other cell wall components, therefore responsible for maintaining cell wall structural integrity. We investigated the role of β-galactofuranose on the structure and physical properties of the hyphal cell wall. Based on its unique capacity to image live samples, atomic force microscopy was used to determine both the ultrastructure … Read more

2012 — Transformations: Treatment for Alcohol Addiction as a Process of Consciousness ExpansionAbstract
A body of research has suggested that an understanding of the lived experience of addicted individuals is an important yet neglected part of developing effective treatments for addictions. In an attempt to further understand the subjective experience of addiction, a phenomenological study was undertaken with the aim of understanding if consciousness studies could inform and enrich current treatments for addiction. Specifically, the study examined the utility of conceptualizing an addiction as a problem of restricted consciousness and its treatment as a process of consciousness expansion. This study attempted to further understanding related to changes in consciousness, and the development of … Read more
