abstract: One of the most popular types of fuel cells is the polymer electrolyte fuel cell (PEFC) with hydrogen as fuel. This generation of the fuel cell is used extensively to convert chemical energy of hydrogen fuel to electricity. It can be used in various applications, from stationary applications to vehicles, due to its small size, low temperature, and pressure. However, the cost and durability of PEFCs remain a barrier to large-scale commercialization. The central R&D target for large-scale PEFC commercialization focuses on lowering the cost without compromising its performance. A significant part of the price and performance of PEFC is linked directly to the catalyst layers. The performance of the catalyst layer is strongly influenced by the ionomer, an ionically charged polymer. This is due to the undeniable influence of ionomers on material transport (oxygen and proton). The ionic moiety, located on the ionomer side chains, helps in proton transport. In addition, oxygen molecules diffuse through the ionomer agglomerates. Therefore, the ionomer local structure has a noticeable influence on ion and oxygen transport. Since the fabrication process of the catalyst layer can affect the ionomer structure in electrodes of PEFCs, this process has a significant impact on the performance of the catalyst layers. As a result, the catalyst layer fabrication process has a considerable effect on the performance of PEFCs. Instead of empirically guided electrode fabrication, a theory-based knowledge of ionomer morphology alteration throughout the catalyst layer fabrication process is required for establishing a manufacturing guideline for high-performance electrodes for PEFCs. For this purpose, the Nafion ionomer, the most commercialized fluorinated ionomer for PEFCs, is modelled during the catalyst layer fabrication steps by the molecular dynamics method (MD) in this thesis. Herein, we study the Nafion ionomer morphology changes at three main stages of catalyst layer fabrication, which are Nafion structure in dispersion media, Nafion orientation in catalyst ink, and evolution of Nafion ionomer morphology during the drying of catalyst ink in the transformation process of catalyst ink to the catalyst layer. First, the molecular assembly of Nafion ionomer in a variety of solvents with various dielectric constants (ε=2.38 to 109) is modelled using all atomistic molecular dynamics to study the aggregate structure of Nafion in practical dispersion systems. Our investigation demonstrates that a range of morphologies exists based on the solvent polarity, unlike the common assumption that Nafion aggregates have an elongated form in all dispersion media. The presence and clustering of ion pairs in Nafion dispersions, which is not previously observed in PFSA ionomer dispersions, is demonstrated in this work. A new aggregation phase diagram for different Nafion dispersion systems is introduced for the first time. Based on this diagram, Nafion can have three different morphology types depending on the dielectric constant of the applied solvent. I. In the low polar solvents (εr ≤ 45), the ionic clusters of side chains cause cross-linked ionomer aggregations. II. In medium polar solvents (εr ~ 57), Nafion has a two-dimensional lamella-like structure. III. The high polar solvents (εr ≥ 78) generates tightly packed elongated aggregates. Also, a novel phenomenon of solvent microphase segregation in water/IPA mixture caused by PFSA's surfactant-like hydrophilic/hydrophobic properties is discovered. We also studied the assembly of the Nafion ionomer on planar Pt, planar graphite, and graphite/Pt nanoparticles substrates in water, IPA, and water/IPA to gain a better understanding of the macroscopic, microscopic structures of Nafion ionomer found in popular catalyst inks. The Pt surface causes the creation of ion-pairs on the substrate in high dielectric solvents such as water, while sulfonic acid is fully dissociated in the water dispersion system. Herein, we showed that the interaction of ionomers with graphite is solvent independent. Nonetheless, ionomer coverage for planar Pt varies considerably, ranging from 72 percent for pure water to 28 percent for pure IPA. Furthermore, increasing the aqueous concentration results in more homogeneous ionomer coverage on the Pt surface. Adding Pt NPs to the surface of graphite reduces the ionomer coverage of graphite in IPA and water/IPA environments by 12 to 15%. Pt NPs have a lower ionomer coverage than planar Pt in aqueous media. As a result, while modelling catalyst ink or catalyst layer problems, the combination of graphite/Pt and the surface shape of the catalyst must be explored. In IPA, some NPs are completely covered by ionomer; however, some are bare. By adding water to the environment, the ionomer coverage of Pt NPs becomes more homogeneous. In the last part of this work, we used fully atomistic molecular dynamics to simulate the dynamic changing of the ionomer structure during solvent evaporation. The examined solvents in this study are pure water, a 50/50 blend of water and IPA, and pure IPA. To investigate the structure of ionomers on the catalyst, we simulated a drying process of ionomer dispersion on a platinum (111) substrate. This work examines ionomer surface coverage, sulfonic group abundance at the interface, ionic clusters' existence and their sizes, and polymer density variation from Pt/ionomer to polymer/fluid interfaces throughout the drying process. Surface coverage analyses show that the ionomer has the lowest coverage (20-48 percent) on the platinum substrate in pure IPA during and after drying. The ionomer surface coverage changes dramatically (from 25% to 82%) in the water/IPA sample because of a change in the nature of the solvent since IPA is more volatile compared to water.

abstract: Stroke, the interruption in blood flow to the brain, initiates a neurotoxic cascade that leads to cell death. The aim of this thesis was to determine the role of Panx 1 channels in the neurotoxic cascade induced by ischemia in the rat hippocampus. Two approaches were taken: (1) the link between Panxl opening and MPT activation was investigated by monitoring dye efflux using live cell fluorescence microscopy, (2) the involvement of Panxl in cell death was determined by Western blot analysis of cleaved cytoskeletal protein, a-fodrin. Ischemia induced opening of the MPT was prevented by blocking calcium influx through Panxl channels. Panxl opening during ischemia also induced calpain proteolysis. This cleavage was prevented when either Panxl or the MPT were blocked. Therefore, opening of Panxl during ischemia activates the MPT and calpain proteases via calcium influx, indicating that Panxl channels induce neuronal death through mitochondria dysfunction and degradation of the cytoskeleton.

abstract: Water allocation regimes in the Western United States and Alberta are compared to determine the applicability of the United States’ Indian reserved water rights doctrine, also known as the Winters doctrine, in the Treaty 7 area of Alberta. It is established that a significant difference in the division of powers between states and the federal government in the U.S., and provinces and the federal government in Canada, prevents application of the Winters doctrine in Canada. It is argued that the assumption of control over the Aboriginal interest in surface waters associated with Indian reserves through the North-west Irrigation Act, 1894 and the recognition and affirmation of Aboriginal and treaty rights in section 35 of the Constitution Act, 1982 give rise to an obligation on the part of the Crown in right of Alberta to furnish priority water allocations for use on reserves in Treaty 7.

abstract: Two design strategies were investigated to enhance proton conductivity of a proton conducting MOF named β-PCMOF2. First design strategy was isomorphous ligand replacement where an entire C3-symmetric trisulfonate ligand was substituted with a C3-symmetric tris(hydrogen phosphonate) ligand to yield PCMOF2½, which had its proton conductivity raised 1.5 orders of magnitude, to 2.1 × 10-2 S cm-1 at 85 °C and 90% relative humidity compared to the parent material, while maintaining the parent MOF structure. To further enhance the proton conductivity of PCMOF2½, isomorphous ligand replacement was paired with heterocycle doping. Seven new PCMOFs were synthesized and investigated. One resulting material, PCMOF2½(Pyrazole), had its proton conductivity raised 1.9 orders of magnitude compared to the parent material, to 1.1 × 10-1 S cm-1 at 85 °C and 90% relative humidity, while maintaining the parent MOF structure. In addition, the exact mechanism of isomorphous ligand replacement synthesis was elucidated to be a thermodynamically driven solid state reaction.

This discussion of Community Development (CD) is offered to provide some insight into the worldview of practitioners as theorists and educators. The CD community is explored through an examination of conferences, using participant observation, surveys and interviews. The conference community is interpreted as a microcosm of the larger society and used as a context to identify issues in CD theory, planning and practice. It discusses how CD practitioners conceptualize their social, institutional and personal environments, and their encounters with those who are poor, elderly, and/or disabled. A literature review of CD is provided, that describes planning and adult education approaches. A descriptive analysis and a rich description of the research findings follow. Finally, there is the discussion of research results, and recommendations. Suggestions for future research are included.

abstract:
Development of gross motor skills and fundamental movement skills, are essential in the growth and development of the child.  If a child does not have the proper development, nor the mastery of gross motor skills, it could hinder their growth and development, and lead to a higher rate of disengagement from activity and sport, and increase sedentary behaviour.  With a larger emphasis being placed on to the recreation and education sectors to ensure children meet the minimum requirements of physical activity and create a healthier population, programs need to be effective in aiding the growth, development and mastery of these skills.  The objective of the study is to determine if a specialised recreation program, designed with the intention to introduce children between the ages of 4 and 5, to multiple activities in multiple environments, aid in the development of fundamental movement skills when compared to their standard recreation counterparts.
A sample of 59-59 children, completed an eight-month, recreation centre-based study.  Twenty-four participants acted as the control group, and were enrolled into parent-selected activities, which would run eight-weeks in length per program.  Thirty-five participants acted as the intervention group, and were enrolled into the specialised program, which swapped between four-environments.  All participants were assessed at two time-points, pre- and post-program, using the Test of Gross Motor Development, 3rd Edition, and the Bruininks-Oseretsky Test of Motor Proficiency, 2nd Edition, which measures locomotor, object-control and balance skills.
The three-way multivariate analysis of variance with one repeated measure and two confounding variables, demonstrated that all participants, regardless of program type, increased significantly from the pre-assessment measures to the post-assessment measures in all skills.  The 3-way MANCOVA also demonstrated that a gender difference was apparent at both the pre-assessment measures, as well as the post-assessment measures, specifically in object-control, wherein males outperformed females.  However,However, there was no significant difference when comparing group.
These findings suggest that regardless of program type, child enrolment does elicit significant improvements of gross motor skill and fundamental movement skill development, over the course of an eight-month intervention.

abstract: Throughout the islet transplantation process, many islets die due to removal from their native environment. Studies suggest that select extracellular matrices (ECMs) have the potential to support islet survival throughout transplantation. However, there is currently no overview evaluating ECM interactions with pseudoislets. In this study, three common methods of quantifying cell survival were applied to aggregates encapsulated in thin hydrogel sheets and their effectiveness was evaluated. Next, a Design of Experiments approach was used to evaluate composite hydrogel ECMs as a method of improving the survival of INS1 and primary human pseudoislets post-isolation. Encapsulating INS1 pseudoislets in [alginate] = 2wt/v%, [collagen I] ~ 4mg/mL, and [Matrigel] ~ 4mg/mL improved INS1 survival and proliferation when cultured for 3 days. Similarly, collagen I and Matrigel were found to have a neutral or positive effect on primary human pseudoislet survival when encapsulated in 2 wt/v% alginate gels and cultured for 5 days.

abstract: This study focuses on issues and approaches related to economic development in three Metis Settlements in north-central Alberta. Residents of these centres view the lack of an economic base as the main reason underlying their social problems and their dependency on government. This study recommends specific economic incentives to address this concern and to advance community well-being and self-determination. A review of regional development literature shows that traditional approaches (e.g., industrial location grants) have largely bypassed remote communities. Instead, this study advocates the targetting of incentives directly to the client group. A combination of jobs, training and business services is advised as the most direct way to facilitate economic improvements. This advice is given together with the need to understand the diversity of Metis Settlement culture in making economic prescriptions. The study profiles socio-cultural differences so that residents' objectives (and problems) may be dealt with as they exist, not as they might be perceived by outside agencies. A set of policy recommendations is developed that weighs public costs against distributional concerns. A process of administrative transfer (led by the transfer of economic program budgets) is advanced as a cost-effective step in Metis job and business creation. By assuming more control over economic planning, the Settlements become partners in development, not simply clients of an end product. A regional, Metis-operated employment service agency is recommended as the mechanism to achieve this. A major economic proposal for the Metis Settlements is analysed as a case study. A tri-Settlement wood-products plant is critiqued from the perspective of local employment concerns.

abstract:
The goal of this thesis is to develop a methodology for enhancing fracture detection and correctly delineating reservoirs with fractures. The thesis deeply explores the mechanical formation of fractures and fractured media, presents an enhanced fracture detection technique that uses a new finite-difference scheme to accurately model fractures and analyze the fracture response in seismic traveltime and amplitude, and develops a method for accurate reservoir delineation by deriving new AVO fracture equations to correctly estimate the properties of the fractured medium, the host medium and fractured medium with impedance contrast.
With the long wavelength assumption, a linear slip interface is equivalent to a fracture interface that satisfies the nonwelded contact boundary conditions. Therefore, the fractured medium can be regarded as a combination of a fracture, or a set of fractures, and a host medium: a horizontally fractured medium is effectively composed of a horizontal fracture embedded into a homogeneous isotropic host medium; and a vertically fractured medium is effectively formed by inserting a vertical fracture into a homogeneous isotropic host medium; an orthogonally fractured medium is effectively assembled from a vertical fracture and a homogeneous VTI host medium, or a horizontal fracture and a homogeneous HTI host medium, or two orthorhombic fractures and a homogeneous isotropic host medium.
New finite-difference schemes for horizontal, vertical and orthorhombic fractures are implemented to generate seismograms that precisely illustrate the fracture representations in seismic data. The results indicate that the fractures are detectable, even though the fractured medium does not have impedance contrasts, and that the fractured medium can be characterized as a transversely isotropic medium. Through an analysis of how fractures are represented in seismic data can help in fracture detection in geoscience.
New exact equations for the reflection and transmission coefficients of a fractured medium with impedance contrast are derived that take into account the azimuthal parameter and the nonwelded contact boundary conditions. New approximate AVO equations that include fracture parameters are derived. Therefore, the fracture, the host medium and the fractured medium with impedance contrast properties can be estimated from seismic data to correctly delineate the reservoir characterization.

Gassy soils

abstract: Gassy sandy soils commonly occur in offshore regions, and slope failures during unloading are often inevitable in such soils as gas bubbles affect the compressibility of the pore fluid and integrity of the soil matrix. The ratio of pore water pressure to total dissolved gas pressure (PTDG) controls if and when free gas forms during unloading. PTDG has commonly been assumed equal to the pore water pressure, which may result in incorrect estimates during modeling and prediction of gassy soil induced failures. In this thesis, both total dissolved gas pressure and pore water pressure in gassy sandy soils were measured in a specially designed laboratory program that involved pressure reductions with undrained rebound conditions. It was concluded that PTDG and pore water pressure are not equal for sometime after the pressure reduction takes place. This difference in the two pressures accounts for the capillary pressure or surface tension effects.

abstract:
This research investigates the problem of analyzing radio astronomical surveys (RAS) to automatically identify groups of objects forming patterns that astronomers are interested to find. The visual inspection of RAS to find these interesting patterns requires a lot of time and effort to go through thousands of images in RAS. Moreover, the visual process can be infeasible in very crowded and noisy images. To tackle this problem, this research presents AIRAS: the first reported system for the automatic inspection of RAS.
AIRAS consists of two main stages; (i) STAGE 1: Object finding where all objects in RAS are found and presented in a graph-based representation called the astronomy graph (AG), and (ii) STAGE 2: Pattern querying and retrieval where astronomers specify the characteristics of interesting patterns in a query form. Afterwards, AIRAS finds patterns matching these characteristics in the AG and presents them to astronomers for further investigation.
Astronomers can use AIRAS to detect patterns known to be suspicious (i.e. they consist of false astronomical objects or artifacts). Among these patterns are the hexagonal pattern (HP) and the zigzag pattern (ZP). In the HP, objects form a hexagon shape with an object in the middle, similar to the shape of the front end of the Arecibo telescope horn. In the ZP, objects are aligned in an orientation with the horizontal axis similar to the scanning line of the radio telescope. These two patterns are used as case studies to evaluate AIRAS performance using images from the GALFACTS project; a project carried out at the University of Calgary in cooperation with several research institutes worldwide.
The experimental studies show that AIRAS is a promising system that finds patterns in
RAS in response to astronomers’ queries with an acceptable accuracy. Additionally, AIRAS can be extended to connect the patterns found with their physical signals to provide more insights about the nature of these patterns.

abstract: The Gore Point Member is a mixed carbonate-siliciclastic unit deposited in the Sverdup Basin (Canadian Arctic Islands) during the Carnian (Late Triassic). While mixed carbonate-siliciclastic deposits are not rare within the global rock record, the Gore Point Member is unique in that it is the only unit with meaningful amounts of carbonate material within the Mesozoic succession of the Sverdrup Basin. However, as detailed sedimentological or sequence stratigraphic studies of the Gore Point Member have been yet to be undertaken, the existence of this anomalous unit remains unexplained. This study applies thin section microscopy and microfacies analysis of 285 samples from 12 sites across western Ellesmere Island, and lithofacies analysis of one core on Mackenzie King Island, to interpret the depositional setting of the Gore Point Member. These observations reveal fine-grained quartz-dominated siliciclastics and heterozoan carbonate material deposited in a ramp setting in an arid, cool-temperate environment. Integration of sedimentological trends with subsurface wireline well logs throughout the Sverdrup Basin reveals deposition across three fourth-order transgressive-regressive sequences. It is postulated that the arid climate along with tectonic quiescence reduced siliciclastic input, providing a window of opportunity for heterozoan biota to propagate. The Gore Point Member is significant as it is one of very few examples globally of a ramp-type carbonate deposit from the Triassic, and the highest latitude and most cool-water example recognized thus far.

abstract:
Undesirable water-in-oil emulsions often form during oil processes. Chemical treatment is a common method for breaking down these emulsions; however, this technique is not always effective. In order to improve the chemical treatment of emulsions, it is useful to have an understanding of emulsion stability. The stability of water-in-oil emulsions depends in part on the surface properties. The surface is composed of natural material present in the produced oil, such as asphaltenes, resins, clays and surfactants, which adsorb on the water-oil interface. Asphaltenes play an important role in stabilizing the emulsion since they irreversibly adsorb at the interface of the water droplets and form a steric barrier or rigid skin that prevents coalescence. An effective demulsifier must disrupt this film in order to accelerate coalescence. However, the chemical treatment design is still done by trial and error partly because the effect of surfactants on interfacial films is poorly understood.
This thesis focuses on emulsions stabilized by asphaltene films. It was previously found that the stability of these emulsions could be predicted from both the compressibility and crumpling film ratio of irreversibly adsorbed asphaltene films. In this study, the effect of surfactants on asphaltene interfacial films is analyzed through the change in film properties. Surface pressure isotherms were measured at 23 °C for model interfaces between aqueous surfactant solutions and asphaltenes dissolved in toluene and heptane:toluene mixtures. Compressibility, crumpling film ratio and surface pressure were determined from the surface pressure isothe1ms. The stability of water-in-oil emulsions was determined for the same systems based on the free water resolved after repeated treatment involving heating at 60°C and centrifugation. Experimental variables included concentration of asphaltenes (5 and 10 kg/m³), concentration and type of surfactant (Aerosol OT, nonylphenol ethoxylates, dodecylbenzene sulfonic acids, sodium naphthenate) and aging time (from 10 min to 4 h). The effect of surfactants on film properties and emulsion stability was found to divide in two distinct behaviours.  1) surfactants that fom1ed reversible films and destabilized emulsions and 2) surfactants that maintained the irreversible adsorption at the interface and could enhance emulsion stability.

abstract:
This research investigates one online professional development program for K-12 teachers to determine if it impacted teaching practice. To do so, it employed the traditions of ethnography (Patton, 1990), case study research (Merriam, 1998) and frame and code analysis (Goffman, 1959, 1974) in an attempt to provide a holistic account of the real-life experience of online professional development for online educators.
 The research methods include the use of digital audio clips to maintain interview authenticity and accuracy. Supported by evidence from the literature of teacher change, teacher professional development, the requirements of online educators and the experiences of the ePD participants, the findings of this research suggest that the ePD program did have an impact on the teaching practice of its participants. This impact was described and interpreted across five frames and their associated codes, which were supported by the literature and validated by the experiences of the interviewees. The frames include: (1) Fundamentals, (2) Change and Impact, (3) Program Design, (4) Implementation and Use, and (5) Learning Culture and Sense of Community. Further, this research suggests that the online teaching and learning environment has different characteristics and possibilities than those previously available in traditional educational settings (Reyes-Mendez et al, 2003).
Consequently, as teachers are now being asked to create online learning opportunities for their students (Advisory Committee for Online Learning, 2001), in an environment they are not familiar with (Stein et al. 1999), they will need support in order to develop their own potential for working online. The ePD program offered by the Calgary Board of Education in Alberta, Canada appeared to be a model that attempts to provide this type of support.

abstract: In the line of duty, public safety personnel (PSP) experience operational stress that may negatively impact their lives at home. While targeted psychosocial interventions are offered to PSP, research indicates that PSP often turn to their spouse/partners for informal psychosocial support (Carleton et al., 2019). Accordingly, spouse/partners may experience secondary stress related to their PSP partner’s occupation while simultaneously managing their family’s needs. Spouse/partners may benefit from resources and support, although no evidence-based intervention programs are presently offered for their unique needs. For the purposes of informing the development of a PSP family program, the current study collected 131 survey responses (51 female; Mage = 42.57) from both PSP and spouse/partners to explore relative strengths and needs. Exploratory factor analysis revealed three underlying dimensions in survey item responses: Parenting and Communication (F1), Family/Peer Support (F2), and Operational Stress and Resources (F3). Analysis of variance examined differences between factors on several demographic variables, including PSP/PSP spouse, sex, police/non-police, family size (i.e., number of children), and municipality size. Spouse/partners consistently expressed greater intervention needs compared to PSP in F1, F2, and F3 scores; female respondents expressed greater intervention needs compared to male respondents in F1 and F2 scores; no differences were found when comparing police to non-police on any factor scores. Planned comparisons yielded between-group differences based on family size and municipality. Families with no children expressed greater intervention needs compared to families with three or more children in F2 scores. Respondents from towns or smaller municipalities expressed greater intervention needs in F1 and F2 scores compared to those residing in cities. Results are discussed in terms of family systems theory and the available literature on PSP families and similar groups.

abstract: Windthrow is a natural disturbance that can result in significant impacts on forests. Modelling of basin-scale patterns of wind speed in subalpine forests of the Canadian Rockies and evaluation of terrain susceptibility to windthrow of trees in these forests have not previously been undertaken. The present study uses the numerical model, WindStation, to simulate wind speed patterns in two mountainous drainage basins in Kananaskis, Canadian Rockies. Locations and associated terrain characteristics where wind speeds for major wind events exceed the threshold of 42 m s-1 are evaluated. Results show that locations where wind speeds exceed the threshold for windthrow and are also treed are limited in spatial extent, occurring mainly at the upper parts of drainage basins close to the drainage divide. Understanding terrain susceptibility to windthrow provides important information about the types of disturbance that control forest dynamics in the subalpine forests of the Canadian Rockies.

abstract: The present study examined the best friendships and the social, emotional, and behavioural functioning of youth from Canadian military families. Further, it examined how the positive and negative qualities of these friendships were related to the behavioural and mental health outcomes measured. Online surveys were administered to 31 military-connected youth to assess internalizing, externalizing, overall problems, and the characteristics and qualities of their best friendships. The results revealed that the average scores for all outcomes were comparable to civilian peers. However, a large minority of participants had elevated internalizing scores. Further, it was found that the best friendships of these military-connected youth were characterized by more positive qualities than negative qualities. Finally, both positive and negative friendship qualities predicted externalizing scores, but they did not predict internalizing scores. Interpretations, implications and limitation of these findings are presented, as are suggestions for future research.

abstract:
SAGD process is used in reservoirs with continuous sand body and high vertical permeability. In western Canada, most of top tier SAGD candidates have already been developed. Many lower tier pools with interbedded shale layers (such as IHS) are available in which current SAGD practices may not deliver an efficient recovery method. The suggested method is to perform a multi-stage fracturing treatment on the injector to open up barriers with vertical hydraulic fractures before steaming. If successful, steam can pass through the barriers, effectively heat the otherwise isolated oil and recover it.
This research has two major components. First, the flow mechanism and recovery response of a fractured SAGD well are discussed to show that the suggested process can improve production rate and recovery factor. The desired fracture properties and expected production rates are obtained by using analytical and numerical reservoir engineering techniques. Through numerical simulation, a matrix of sensitivity cases is made on key fracture parameters. It is shown that fractures with short half-length but high conductivity are required. Using the sensitivity results, an optimum range of the key fracturing parameters and general design criteria are determined using a new dimensionless fracture conductivity definition.
In the second part, some geomechanical topics to be encountered are discussed, starting with a review of relevant hydraulic fracturing field trials in oil sands. Some interface crossing criteria are reviewed and the extended Renshaw and Pollard criterion is used to study fracture propagation through sand-shale interfaces. These results are then compared to results from a coupled reservoir-geomechanics-fracturing simulation software. It is shown that tensile hydraulic fractures can be created in the oil sands, and fractures can cross sand-shale interfaces and be filled with desired concentration of proppant. It is also shown that small but high conductivity fractures (required for success of the proposed method) can be generated by using currently available proppants and fluid systems. The design considerations for various liner systems that can combine fracturing process and SAGD phase are discussed and a few new designs are proposed. Finally, a step by step roadmap for field implementation of this novel method is presented.

abstract: n rural communities, such as Olds, Alberta, energy may be produced though anaerobic codigestion of municipal, agricultural and agro-industrial wastes. An inventory within a 40km radius of Olds revealed that almost 600,000 tonnes of waste are generated annually (98.4% manure) with an electrical potential of 83 GWh. Analysis of beef, hog, dairy and poultry manure, offal, food, grass and biosolids identified the potential for waste blending to optimize solids content and nutrient balance. In laborat01y tests, biogas yield increased from 0.382 m3/kg volatile solid (VS) with beef manure to 0.513 m3/kg VS with co-digestion of 30% hog manure, and 0.500 m3/kg VS with 30% offal. In pilot tests, methane content was increased from 58% to 63% through co-digestion of beef manure with beef manure. The increased yield observed in the laboratory tests was not confirmed due to process inhibition and the limited capability for process control in the pilot digesters.

subject:
Literature--Medieval
Mio Cid

abstract: The research presented in this thesis deals with the first extensive narrative work in Spanish literature, that is, the Cantar de Mio Cid (XII - XIII centuries). The research interest focuses on the jokes and humorous language found in the work. The study focuses on an in-depth analysis of these same elements, to date largely unexplored, or generally carried out superficially. This may be a result of the controversy that concerns their true presence in the Cantar. However, the thesis and arguments presented herein argue the validity of the methodological approach; that is, regardless of the conscious or unconscious inclusion of these elements in the Cantar, the fact remains that they exist in the text and are closely related to burlesque humour. Those jokes and humorous language have a clear proselytizing and warlike function and intent, and include the subtle fostering of a certain hatred and anti-Semitism latent in the period. The arguments and analysis presented in the course of this work are corroborated by the results of a textual, historical, and sociocultural interpretation of the Cantar de Mio Cid, as well as the theory of jokes, according to Sigmund Freud.

abstract:
Success...how can we define and achieve a recognizable, compelling and admirable success? Many studies done by different researchers indicated that there is no definite general agreement on the definition of success or the contributing factors. On the other hand, there is not much disagreement on the definition of failure.
A persistent high rate of projects that were unsuccessful in meeting their targets has haunted many industries and organizations, posing the research main question: Why do many projects fail to meet targets of budget, schedule, quality or performance in spite of the fact that management methods and techniques are widely available, applied science and technologies are rapidly improving and advancing?
Research has shown that a large number of projects were managed mainly as technical systems rather than behavioural system, with relatively little attention being paid to the human factor.
Literature examining soft aspect management is scarce; however, a new trend in research began to recognize the critical importance of the human factor, thus, the first part of the eight chapters in the body of this thesis is dedicated to developing in-depth understanding of the human factor effect and identifying relevant and critical strategic success factors.
The area of focus is the front-end planning, in particular, the strategic pre-planning stage. The second main part in this thesis presents a modern management model including significant numerical weighting values. This model was structured based on literature findings, relevant knowledge obtained from social, culture, psychological and behavioural sciences, results and analyses of an undertaken survey and interviews for the purpose of this research.
The triangulation approach as the strategy of choice is well suited for the thesis objectives and offers great benefits through the application of multi-methods, including qualitative (grounded theory) and quantitative analysis. Data collection, analyses and validation progressed consistently aided by multiple rounds of Delphi technique.
Thesis deliverables included a new practical definition for success and a novel management model featuring a systematic evolutionary methodology designed to modernize management philosophy, generate optimum strategic management decisions and increase the probability of success and achievement.

abstract:
Objectives: To determine the continuing medical education (CME) needs of Canadian and Calgary nephrologists.
Methods: A mixed-methods approach was taken to determine the educational needs of Canadian and Calgary nephrologists. Data collected included a survey of members of the Canadian Society of Nephrology, individual interviews with Calgary nephrologists, individual interviews with editors of nephrology journals, maintenance of certification data from the Royal College of Physicians and Surgeons of Canada, and administrative data on hospital admissions from the Foothills Medical Centre (Calgary, Canada) nephrology inpatient service.
Results: In general, nephrologists participate in traditional CME, both locally and at national/international conferences, and perceive CME as serving multiple functions, including identifying learning needs, improving learning, and providing opportunities for networking and socializing with colleagues. Although they rate the quality of their current CME activities highly, there are diverse opinions on the ideal content and format of CME. Most, however, appear to prefer in-person to on-line activities and are interested in content areas that they do not encounter frequently while attending on clinical service. A mixed methods approach helped identify key similarities and differences that spanned two or more data sets in the domains of local CME/CPD planning, content characteristics, content topics, format, collegial interactions and barriers.
Conclusions: A mixed methods approach to the determination of educational needs of nephrologists provided data that will enable the development of a local CME/CPD program for nephrologists.

abstract: There has been an increasing usage of fossil energy due to our current way of life. This has led to our late realization of major problems such as global warming and the inevitable depletion of our fossil energy resources which has pushed the world to direct its attention towards renewable energy resources such as wind and tidal energy. Since our planet is mostly covered in water, there are many opportunities for exploring the great potential of tidal energy as a renewable energy resource. In an attempt to cope with these developments, the work presented in this thesis is intended to provide high-fidelity computational tools which are capable of modelling complex flow phenomena in the marine engineering sector. Such computational tools can help engineers create better designs and push the boundaries of the current state-of-the-art technology. In this thesis, we provide a numerical formulation capable of modelling pure-hydrodynamic flows, multi-phase flows and multi-fluid flows over complex marine devices. The set of equations governing our multi-phase, multi-fluid flow consists of the Navier\textendash Stokes equations together with a transport equation governing the water-vapor volume fraction in the computational domain, and a conservation equation of a geometric function, namely, the signed-distance-function describing the air-water interface in the context of the level-set method. For applications on moving marine devices, we adopt an Arbitrary-Lagrangian-Eulerian (ALE) description of the continuum where domain motions occur independently of the fluid flow. Moreover, the variational multi-scale method (VMS) is used for turbulence modelling resulting in the so-called ALE-VMS formulation. The formulation is first used for investigating the performance of vertical-axis hydrokinetic turbines installed in in-line arrays in a pure hydrodynamic flow. Second, multi-fluid flow simulations are performed to investigate the effects of the free-surface phenomenon on the performance of hydrokinetic turbines with the aid of the level-set method. Third, the multi-phase modelling capabilities are validated against challenging benchmark problems, namely, the cavitating flow over hemispherical fore-bodies, and the cavitating flow over the INSEAN-E779A marine propeller.  As a proof of concept, the stability of the numerical solver is tested in a simulation of a hydrokinetic turbine under severe cavitation conditions. Our results show robustness of the presented formulation over a range of complex applications.

abstract: This research addresses how governments consider and implement policy in Canada. Specifically, it assesses what factors influence policy success by exploring the market-based instrument (MBI) implementation gap in environmental management in Alberta. Due to the increased complexity of environmental issues and increased expectations that non-state actors will have a role in environmental management, the Government of Alberta made many commitments to use MBIs. However, of the 57 MBI commitments made by the Alberta Ministry of Environment (MoE) during the study period, 2000 to 2015, only 13 were implemented and only 7 are uniquely new. Results reveal that the values, beliefs, and behaviours of policy actors, both internal in the MoE and external stakeholders, influence their social acceptance and the institutional fit of MBIs. However, these factors are not reflected in policy design and implementation processes. Observations and interviews with local knowledge experts revealed issues of accountability and legitimacy contribute to the MBI gap. Further, a Q methodology study revealed prevalent social discourses on water management issues and suggested directions for local solutions. Five distinct discourses were identified around water management issues and four distinct discourses on the use of MBIs as solutions. A number of MBI researchers and designers have made assumptions about how people behave based on traditional economics. This study shows that many such design criteria and objectives do not represent how policies are implemented in real-life scenarios, building on economic principles and taking an interdisciplinary approach to understand how and why policy actors behave the way they do. This research suggests a broadening of policy processes to include social acceptability and informal institutional measures to capture important factors that can influence environmental policy success.

abstract: Justice motive theory provides an account of people’s reactions to violations of their belief in a just world and the variable ways they will attempt to maintain their view of the world as just. Work in the area has extensively examined observer reactions to the fates of others.  Less is known about how people react to injustice associated with their own outcomes. The present research examines justice relevant factors associated with experiencing injury or illness including fairness, deservingness, and the potential moderating effects of severity and responsibility. To assess these factors correlational, regression and MANOVA analysis were used. The potential for injury and illness to give rise to fairness and deservingness concerns was apparent for many but not all participants. In addition the hypothesized just world protective strategies of self-blame, self-derogation, compensatory cognition, and reevaluating the outcome were evident in participants’ reactions to infirmities.

abstract: Botulinum toxin type A (BtA) injections to reduce spasticity for children with cerebral palsy (CP) are often accompanied by physical therapy (PT) treatment.  This series of studies examined current PT strategies across Canada using survey methodology, and evaluated outcomes after PT and BtA injections using single subject methodology.  Survey results revealed that variation in therapy most often related to the child’s functional level and the goals of the intervention.  Outcomes after PT and BtA injection indicated that PT may help prolong the effect of BtA on range of motion, but long term functional improvements were not sustained.  Care pathways for PT treatment were developed, incorporating the literature, current practice and study results.  More work is needed to identify the effectiveness of specific PT treatments for children with CP after lower limb BtA injections; this work will support ongoing updates and reviews of existing care pathways.

abstract: Proteoglycan 4 (PRG4) is a glycoprotein in synovial fluid (SF) and on the articular cartilage surface, where it acts as a boundary lubricant. Hyaluronan (HA) is another SF constituent that acts as a boundary lubricant at the cartilage-cartilage biointerface and interacts with PRG4 to synergistically lower friction. The meniscus is a fibrocartilaginous pad in the knee, on which PRG4 exists, that is critical for joint health. This thesis aimed to develop an in vitro lubrication test to determine the boundary lubricating ability of PRG4 and HA, alone and in combination, at the cartilage-meniscus biointerface, and assess the surface adsorption of recombinant human PRG4 (rhPRG4). A novel cartilage-meniscus test demonstrated that (rh)PRG4 and HA, alone and in combination, act as effective boundary lubricants at this biointerface. rhPRG4 adsorbed to the meniscal surface. This work contributes to the understanding of meniscus lubrication and potential development of osteoarthritis biotherapeutic treatments.

abstract: The study of wartime popular sheet music produced by Anglo-Canadians is vitally important, as it illustrates what was popular in society and demonstrates how Canadians reacted to the world around them. During the First World War, the medium of patriotic sheet music catalysed the management of morale during on the home front, as it offered an emotional outlet for thousands of people in desperate need of a diversion from the grim reality and toll of the war overseas. The cover illustrations, lyrics, and musical scores of hundreds of patriotic songs offer a useful lens into contemporary Anglo-Canadian society in the late nineteenth and early twentieth centuries, as composers immortalized popular conceptions of war, identity, and responsibility on the pages of their songs. Patriotic sheet music therefore demonstrates the popular trends that led so many young boys to war in 1914, and helps to explain how Canadians reacted to the war on the home front.

abstract: This work presents experimental and simulation studies to design and optimize urea solutions to improve bitumen recovery. Initially, the solubility of ammonia in Athabasca bitumen was measured at vapor-liquid equilibrium (VLE) condition at different temperatures and pressures ranging from 348 to 463 K (75 to 190 ℃) and 1 to 4 MPa, respectively. The liquid phase density of ammonia-saturated bitumen was measured. The experimental solubility and density data were modeled using the Peng-Robinson equation of state (PR-EoS) by tuning the binary interaction coefficient and volume shift parameters of ammonia, respectively.  The modeling results revealed that PR-EoS gives an acceptable prediction of ammonia solubility in bitumen and density of ammonia saturated-bitumen. Additionally, 1-D sand pack flooding experiments were conducted to recover heated bitumen at 423 K and 3.447 MPa pore pressure by injecting two different concentrations of urea solutions (5 and 10 wt %) at 1 cm3/min injection rate. Another flooding experiment was conducted by flooding sand pack with fresh water at the same flooding condition to be used as a baseline of urea solution flooding experiments. Supplementary experiments such as interfacial tension (IFT) measurements, emulsion viscosity measurements, total acid number (TAN) measurements, and Fourier-transform infrared (FTIR) measurements were conducted to prove the generation of in situ surfactants through the flooding process. The results of these flooding experiments (at 423 K) showed that flooding with urea solutions improves the oil recovery efficiency, highlighting the synergy between the reduction in viscosity of bitumen and the generation of in situ surfactants. Besides the reduction in viscosity of bitumen resulting from the heat, the generated in situ surfactants emulsify the oleic phase leading to the generation of W/O emulsion at the displacement front. This emulsion makes the displacement front more stable due to the attenuation of the viscous fingering. The supplementary experiments confirmed the generation of in situ surfactants, as evidenced by the reduction in the interfacial tension and total acid number measurements, and confirmed the results with FTIR analysis. Along with flooding experiments, a fine grid numerical simulation was conducted to model the experimental oil recovery data to obtain relative permeability curves through history matching technique. The history matching results revealed the efficiency of urea solutions to change the rock wettability toward more water-wet and suppress viscous fingering phenomenon. After confirming the mechanism of urea solutions in recovering bitumen, several 1-D sand pack flooding experiments were conducted by injecting hot urea solutions into cold sand packs at room temperature to optimize the injection rate, injection temperature, and urea solution concentration. Three injection rates (4, 8, and 12 cm3/min), four injection temperatures (453, 473, 493, and 513 K), and three urea solution concentrations (5, 10, and 15 wt %) were investigated in these flooding experiments. The flooding experiments of cold sand packs revealed an optimum flow rate that leads to more efficient displacement of oil by urea solutions. The optimum flow rate is attributed to the balance between the retention time and heat delivered to the oil sands through the flooding process. The results show higher oil recovery at higher concentrations of urea.  Furthermore, the results reveal that while higher injection temperature accelerates the oil recovery initially, it reduces the ultimate oil recovery.

abstract: Research suggests that depressed individuals experience more difficulty disengaging attention from negative information (e.g., Everaert et al., 2012; Joormann & D’Avanzato, 2010; Koster, et al., 2011), although not all studies have reached this conclusion (e.g., Karparova et al., 2005; Wisco et al., 2012). In the present study, differences in attention disengagement were examined in currently, remitted, and never depressed women. Eighty participants completed an attention disengagement task while viewing emotional images. The time taken to shift their gaze away from the image was used as the measure of attention disengagement. For remitted and never depressed women, the disengagement task was completed before and after a sad mood induction (MI). Currently depressed participants were not found to disengage more slowly from negative images than never depressed participants. There was evidence that the sad MI affected disengagement for the remitted depressed participants who were most affected by the sad MI. The implications of these findings are discussed.

abstract: The ever-growing oil and gas industry has led to the high demand for technologies which accurately sense defects in underground pipelines. Creating a cost-efficient, real-time monitoring system is very challenging. Radio frequency identification (RFID) based sensors are a hot topic for use with buried pipelines because they do not require batteries and are very affordable. Most RFID systems do not function optimally in the presence of magnetic materials especially carbon steel pipes that are prevalent in the Oil and Gas industry. This thesis proposes a passive RFID sensor platform which can be attached to buried pipes. Using magnetic induction-based communication, the designed platform intends to function correctly no matter the soil composition. Simulated, and experimental results are presented and compared. Different communication methods are detailed, and a new sequential-based method is introduced which shows great immunity to the interference effects of metal on conventional RFID systems.

abstract: "Broken Treaties" offers a comparative assessment of Indian treaty implementation focusing on the U.S.-Lakota Treaty of 1868 and Treaty Six (1876) between Canada and the Plains Cree, through 1885. The thesis is that the label of "broken treaties," imposed by nineteenth-century observers and perpetuated in the historical literature, has obscured the implementation experience of both Aboriginal and non-Aboriginal participants and distorted understanding of the relationships between them. This has led to the erasure of the viable relationship through which the United States and the Lakota effectively mediated the cultural divide between them in the period 1868-1875, and stifled appreciation for the broader context of U.S. politics that undermined a treaty solution to the Black Hills crisis of 1876. In Canada, the "broken treaties" tradition has obscured the fact that Canada and the Plains Cree held different understandings of the treaty - contract versus covenant - and that failure to appreciate each other's position fostered the friction exposed in the events and aftermath of the 1885 Rebellion.

abstract: The concept and description of the visco-skin, and it's effect on heavy oil productivity is introduced here. A numerical simulation study was conducted to quantify the visco-skin that develops in the near wellbore region for a typical heavy oil reservoir in Alberta, Canada. The simulator was also used to predict the effect of visco-skin on heavy oil production rate, inflow performance relationship (IPR) curves, the presence of gas on oil relative permeability and well productivity as a function of the visco-skin parameters. Two analytical models are developed. The first model can be used to calculate the flow rate from a reservoir if the visco-skin parameters are known and the second model can be used to calculate the visco-skin factor. The analytical models were compared to numerical simulation and found suitably accurate for first approximation calculations. The numerical simulator was finally used to study the effect of well productivity when the visco-skin was melted away using an electromagnetic heating technique. It was found that the visco-skin depends primarily on two parameters, the live oil viscosity at the bubble point, and the dead oil viscosity, for a given reservoir. Both of these parameters are measurable in the lab. It was also found that the visco-skin develops within one meter of the near wellbore region in a short period of time and does not progress further into the reservoir, even after one year of primary production. Results from the simulation studies indicate that the viscoskin can decrease well productivity by a factor of two for the heavy oil reservoir used in this study. Also that the use of heat produced by electromagnetic stimulation, to melt the visco-skin, results in immediate enhancement of oil productivity by a factor equivalent to the visco-skin. The simulation results for electromagnetic stimulations are verified by actual field data.

abstract: NAFLD includes a spectrum of disease from minor steatosis to hepatic inflammation, and can develop into fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Due to the obesity epidemic, NAFLD is rapidly emerging as the most common chronic liver disease worldwide. Although the exact pathogenic progression of NAFLD is ambiguous, the evolution from steatosis to NAFLD is currently considered a multi-hit approach involving inflammation that may promote progression of the disease, although there is very little data regarding immune response to pathogens in the context of NAFLD.  The hypothesis states the immune response to viral infection in the context of fatty liver is hyperinflammatory, resulting in accelerated and increased liver damage. Intravital microscopy (IVM) is a sophisticated imaging approach that allows us to see cellular interactions and behaviours in real-time in vivo. IVM of the fatty liver revealed anatomical changes to the liver after high fat diet (HFD) and a pro-inflammatory resident macrophage phenotype. After infection with S. aureus, HFD mice had decreased platelets and NETs in the liver, while plasma IL-17 was increased compared to control. However, NAFLD mice showed similar bacterial loads and alanine aminotransferase (ALT) levels compared to control. Infection with adenovirus resulted in a delayed GFP expression but increased liver damage as assessed by ALTs. Importantly, flow cytometric analysis showed exhausted T cells from NAFLD mice that did not activate as well as control T cells after stimulation, while IVM revealed no behavioural dysfunction of T cells from NAFLD mice post-viral infection. Overall, these results reveal small but important alterations in the immune response to both bacterial and viral infection in the context of NAFLD.

abstract: Dynamic information in the environment often stems from multiple modalities, such as auditory and visual (audiovisual; AV). The ability to detect and integrate AV information draws attention to salient information, allows for efficient processing, and helps individuals learn sound-object associations, which can impact language development. In this dissertation, I explore stimulus characteristics that affect how AV information is integrated and processed in 4-and 5-year-olds and the relation to their receptive language (RL). In Chapter 2, I examine whether 4-and 5-year-old’s integrate AV stimuli resulting in faster and more accurately responses to matched AV compared to mismatched AV and unisensory stimuli. This was the case. I further hypothesized that responses to matching AV stimuli would predict children’s RL, which was not supported. Moreover, I hypothesized that children’s executive functioning would predict responses to mismatched stimuli, which was the case. Thus, children integrate AV information and their broader skills impact how quickly and effectively they respond to information in their environment. In Chapter 3, I use EEG to investigate 4-and 5-year-old’s processing of AV synchronous/ asynchronous human/ monkey videos. I found increased processing for mouth movements paired with vocalizations (i.e., synchronous), compared to mouth movements alone, and for auditory human, compared to monkey, vocalizations. Synchrony and species affected AV processing differently based on the modality (i.e., auditory or visual) being examined. In Chapter 4, I expand on the work in Chapter 3 to examine whether children’s neural responses are related to their RL. Here I found that 4-year-old’s processing of visual synchronous and 666ms asynchronous stimuli were related to their RL. However, no significant relation was found for the 5-year-olds. For both ages, reduced processing for auditory stimuli, iii regardless of synchrony and species, was related to higher RL. This may suggest that children who reduce processing to nonsense vocalization have more cognitive resources to process meaningful information and had higher RL. I conclude by discussing the importance of understanding the nuances of AV integration and processing in early childhood as these foundational skills are related to their development. This provides a base for future research to explore AV integration in atypical development.

abstract: This thesis uses a survey conducted in the summer 1997 to provide an economic valuation of recreation users for the reach of the Bow River below the Ghost Dam to Highway 22. The survey responses indicate that a single site travel cost model is appropriate to estimate the value for these users. Groups surveyed include; canoeists, rafters, and kayakers. The quality of recreation experience is both directly and indirectly related to instream flow. Thus to effectively understand management trade-offs for competing uses of a river, economic valuation for recreation users is required to demonstrate a need for river obstructions such as hydroelectric dams to manage instream flow rates for multiple users.

abstract: Zinc is found in multiple brain areas where it can act as a neuromodulator of postsynaptic receptors. There is evidence for the existence of zinc in the SCN as well as its vesicle transporter (ZnT3) in the retina. However, its presence in other circadian areas has not been examined. This study observed the anatomical distribution of zinc in the SCN and IGL as well as ZnT3 in the retinal ganglion cells that project to these areas. The role of zinc in photic entrainment was also examined. The IGL contained considerable amounts of zinc while ZnT3 was present in retinal cells that are able to project to the IGL. Nevertheless zinc in the IGL was not implicated in the photic entrainment pathway and the retina was shown not to be a necessary zinc input source. Together, these results present the first report of zinc in the IGL and circadian retinal projections.

abstract: The current study examined the relationships between in-service and pre-service school psychologists’ knowledge of ADHD, ADHD stigma perceptions, and level of education and experience. Forty-five in-service school psychologists and 27 pre-service school psychologists completed online self-report measures. Results indicate that in-service school psychologists have significantly higher ADHD knowledge than pre-service; however, these groups did not differ in their ADHD stigma perceptions. Results also suggest that it is only ADHD-specific experience, and not knowledge of ADHD, years of experience, or education, that relate to ADHD stigma perceptions. These findings have implications for the training of school psychologists, as well as possible interventions for improving knowledge and perceptions of stigma in ADHD.
