abstract: Solvent-based processes such as vapor extraction (VAPEX) can be another technology that has potential to enhance heavy oil recovery in a more cost-efficient and environment friendly way. Extensive experimental and simulation studies have been conducted to evaluate VAPEX. However, theoretical modeling has not gained much progress in the past two decades. This thesis aims at adopting a series of mathematical models for a new theoretical analysis of comprehensively evaluating solvent-based recovery processes and also attempts to develop a new process to enhance production. This thesis first develops a comprehensive theoretical analysis method for VAPEX, which considers all the major recovery mechanisms such as dynamic mass transfer, gravity drainage, multiphase flow, and boundary movement in the model. Both constant and variable diffusivity have been studied in this model, and the latter justified in the progressive change of properties such as viscosity in the media within the diffusion layer. A hot solvent injection process takes advantages of both thermal recovery processes (quick heat conduction and large viscosity reduction) and solvent-based processes (lower energy consumption and less green-house gas emission). This thesis then develops a transient mass transfer model to analyze the cold heavy oil–hot solvent mixing process during a hot solvent injection process. This mass transfer model is then incorporated into the VAPEX model to evaluate the performance of a hot solvent injection process. Key indicators such as oil production profile, injection pressure, injection temperature, solvent oil ratio, etc. have been studied to find out a quantitatively correlation. A new hybrid process, SAVE, is proposed to enhance heavy oil recovery. In this process, a short-slug steam and a long-slug solvent are alternately injected to extract heavy oil. Simulation results show that the cumulative steam-oil ratio of SAVE is 37.26% of that of SAGD. In comparison with VAPEX, SAVE produces oil 8.4 times faster than VAPEX and its cumulative solvent-oil ratio of SAVE is only 26% of that of VAPEX. SAVE performs relatively better in thinner formations than in thicker ones.

abstract: This thesis examines the haptic and sensuous registers of French director Céline Sciamma’s feature works and their embodiment of the sensuous and affective registers of cinema, exemplifying an alternative to the male gaze. Considered one of French cinema’s most prominent contemporary feminist filmmaker, Sciamma’s works are relatively new and thus underexplored within Anglo-Western feminist, media and film studies. This thesis relies on the theoretical frameworks outlined by seminal film phenomenologists Vivian Sobchack, Jennifer Barker, Laura Marks while also making reference to foundational scholars of Western ocularcentric thought and psychoanalysis: Jean-Paul Sartre, Jacques Lacan and Sigmund Freud. Films researched comprises of Sciamma’s directorial oeuvre up to the year 2020, Water Lilies (2007), Tomboy (2011), Girlhood (2013), and Portrait of a Lady on Fire (2019). This thesis argues that the male gaze relies on vision’s privileged place atop the sensual hierarchy in Western thought, thus the corporeal, affective registers palpable Sciamma’s works allow for an alternative to the male gaze. This thesis also briefly explores the implications of such a filmmaker within the current landscapes of cinema and feminism in France and sparks new scholarship within this intersection.

abstract: After knee ligament injury, specifically anterior cruciate ligament (ACL) injury, the articular surface frequently becomes damaged and can lead to post-traumatic osteoarthritis (PTOA). PTOA is a common joint disease and involves the breakdown of the cartilage that covers the ends of the articular joint-bone interface. PTOA development can be attributed to many factors, two of which may be altered kinematics and joint inflammation. Presently, no treatment options are effective in slowing PTOA progression. Therefore, it is crucial to better understand both joint biomechanics and inflammation. Further, studying interventions that have the potential to mitigate inflammation is necessary to find strategies that may prevent the damage from setting in. Therefore, the rationale for this thesis was to 1) determine if partial ACL (p-ACL) transection (Tx) model leads to PTOA (Project A), 2) determine if p-ACL Tx leads to kinematic alterations (Project B), and 3) determine if p-ACL Tx induced joint inflammation can be modified by glucocorticoid (GC) treatment (Project C). We hypothesized that early inflammation following p-ACL Tx in an ovine model would initiate degeneration of the knee joint and that methylprednisolone acetate (MPA; Depo-Medrol®) treatment would mitigate injury-related PTOA development. Furthermore, MPA would provide a mechanism of long-term prevention to joint damage by suppressing acute inflammation. The results showed that p-ACL Tx led to significantly more combined gross damage at 40 weeks post p-ACL Tx than the control group. There was considerable inter-subject variability following p-ACL knee injury within animals. There were consistent changes in medial-lateral, posterior-anterior, and inferior-superior translations at 40 weeks from intact to after p-ACL Tx. In normal explants, MPA treatment suppressed IL-1β induced mRNA levels for matrix metalloproteinases (MMPs) in articular cartilage, synovium, and infrapatellar fat pad (IPFP) and was found to be tissue-, location-, and gene-specific. Although the gross damage was not significant at 20 weeks post p-ACL Tx compared to the control group, there were trends indicating that the damage was progressive over time and that MPA mitigated gross damage at 20 weeks post p-ACL Tx. The in vivo 20 week studies provided efficacy to determine if we could detect changes early. However, perhaps a greater differential in PTOA damage is necessary to see an impact of GC treatment in a long- term model, comparable to that observed in the 40 weeks post p-ACL Tx group. Last, there were no significant bone changes at either the early 20 weeks post p-ACL Tx or the advanced 40 weeks post p-ACL Tx, compared to non-operative control tibias in any of the subchondral bone layers, thus suggesting the degree of joint instability (full ACL Tx vs. p-ACL Tx) appears to influence the response in bone microarchitecture.

abstract: Les écoles d’immersion française ont été introduites au Canada anglais dans les années 1970, suivant l’établissement officiel du bilinguisme national. La reconnaissance au niveau fédéral des droits linguistiques des Franco-Canadiens a découlé de l’état désavantageux de ces derniers sur le plan économique. Il fallait équilibrer les possibilités entre les anglophones et les francophones, en adoptant le bilinguisme le plus possible dans la société canadienne. Un des buts donc de l’éducation bilingue – comme toute tentative de bilinguisation de la population canadienne – était celui de rapprocher les opportunités pour les deux groupes de langues officielles. En principe, enlever les barrières linguistiques entre eux permet aux anglophones et aux francophones de se parler aussi. Qu’est-ce qu’un pays en solidarité sinon un pays où les citoyens partagent la parole? Ce mémoire explore les représentations sociolinguistiques des élèves qui sont formés dans le système d’immersion française en Alberta. Étant donné le contexte anglophone de cette province, quelles seront les ramifications d’une éducation en français sur leurs identités linguistiques et culturelles? Les données analysées ont été recueillies lors d’une période d’observation participante (méthode ethnographique), et des interviews interactives avec des étudiants du même groupe. Si les écoles d’immersion française étaient censées résoudre un problème socioculturel – équilibrer et créer une solidarité entre les « deux solitudes » – comment les diplômés du système se comprennent-ils par rapport à cet idéal?

abstract:
Type 1 diabetes is a disease of the pancreas in which the beta islet (endocrine) cells, which are responsible for insulin production, are destroyed by the immune system.

   The expansion in bioreactors and subsequent transplantation of endocrine cells could revolutionize the treatment for Type 1 diabetes using the "world-famous" Edmonton Protocol. Consequently, the aim of this study was to develop a scaleable process to expand mammalian pancreatic endocrine tissue in suspension bioreactors. Issues regarding cell culture medium conditions and cell handling protocols were investigated. Experiments in suspension bioreactors for 9 days showed a greater than 7-fold increase in the number of insulin-positive cells. Furthermore, aggregates were islet-like, as all of the endocrine cell types were present. Most importantly, cells exhibited glucose-responsive behavior and thus functionality..

These results represent a major milestone on the path to effective expansion and clinical use of bioreactor-produced islet-like structures in the treatment of Type 1 diabetes.

abstract:
Spouted beds are widely used as gas-solid contactors in various physical and chemical processes. In order to improve the design of spouted beds for efficient gas-solid contact, a better understanding of the complex flow field of granular solids is required. The recognition of flow regimes is also very important in the application of spouted beds.
In this thesis, numerical modeling using FLUENT 6.3 commercial software was utilized to study the flow in a slot-rectangular spouted bed. Two-phase gas-solid flows in the bed were simulated with the computational fluid dynamics (CFD) technique using the two-phase Eulerian-Eulerian granular model. Two-dimensional computer simulations were performed to investigate the effects of physical parameters on the hydrodynamic behavior of slot-rectangular spouted beds. The fountain height and pressure drop were evaluated for various superficial gas velocities, bed heights, and solid particle sizes. The numerical results of the fountain height were in good agreement with the experimental data reported elsewhere.
The numerical simulations were applied to predict different flow regimes and construct flow regime maps. The constructed flow regime map for a bed containing solid particles with a diameter of 1.44 mm was in good agreement with an experimental map previously reported elsewhere. With this successful numerical mapping, a flow regime map for particles with a diameter of 3.77 mm was constructed for various superficial gas velocities and static bed heights. The map was composed of six distinct flow patterns, i.e., fixed bed, internal jet, jet-in-fluidized-bed, spouting, incoherent spouting, and slugging. The slugging flow regime occurred at large values for the static bed height and air inlet velocity, while the spouting regime arose by increasing the air inlet velocity at low values of static bed height. Unlike the spouting regime, large pressure drop fluctuations were observed in the incoherent spouting regime.

abstract:
Zero (Ø) has been a phonological tool for over a century used to explain linguistic phenomena where language-specific rules either under or over-apply. This tool has often been argued to be 'dangerous' since it gives 'additional power to the system' (Stanley 1967). This long-standing controversy has lead to many authors arguing against analyses of phenomena that rely on Ø. This opposition to Ø often leads those authors to relegate a given phenomenon to the lexicon rather than maintaining a phonological explanation for a given sound change.
While the skepticism of those authors may be warranted, what is lacking from the field is a list of criteria by which to evaluate proposals of Ø. This thesis examines cases of proposed Øs in several languages to propose a list of four criteria which can be used as a general guideline for either warranting or eliminating Ø in a particular phonological analysis.

abstract: Tourism discourse has been affirmed to be a site where tourist destinations are constantly invented, reinvented, produced and reproduced. More importantly, tourism discourse constantly undergoes variation along with the changing social context and the unfixed power relations between host and guest society. By using critical discourse analysis to analyze the New York Times travel writings covering Shanghai and tracing the evolving discourse, it is discovered that the newspaper increasingly projects the image of Shanghai as a metropolis for diverse consumption by adopting commercialized language, and consequently cultivates a homogenized discourse and routinized ways of viewing Shanghai. It is concluded that the changing discourse suggests the newspaper’s closer relationship with the tourism industry, and the travel writings have become the product of consensual marketing for profitability and reflect the collaborative relationship between the newspaper and the tourism industry of Shanghai.

abstract: The prevalence of diabetes continues to rise, making inpatient management of diabetes an increasingly relevant issue. In teaching hospitals such as those affiliated with the University of Calgary, inpatient management of diabetes is often the responsibility of learners including residents and medical students. Several studies have demonstrated that learners lack knowledge and confidence in inpatient insulin management. To improve the way learners are taught about inpatient insulin titration, we sought to elucidate what contextual factors and mechanisms of an educational intervention are more likely to improve glycemic outcomes, and what factors, both conscious and subconscious, learners consider when making decisions about insulin titration. To determine the contextual factors and mechanisms of successful diabetes educational interventions, we conducted a realist synthesis. After analysing 21 studies, we found that interventions that improve the insulin prescribing process are necessary but not sufficient to improve glycemic outcomes. In-person, group, prescriber-specific interventions with a reinforcing intervention are more likely to be successful. To study the factors that learners consider when titrating insulin, we conducted a mixed methods study using a case-based survey loosely modelled on script concordance testing. We found that medical students prescribed insulin with greater concordance with staff endocrinologists than residents, yet residents had more confidence than medical students in their prescribing practices. Overall, the residents prescribed larger doses of insulin. The residents were susceptible to the subconscious influence of the seniority of the nurse asking for an insulin dose, yet the medical students were not. Both groups of learners prescribed more insulin in the presence of ketones and less when the patient had hypoglycemia unawareness. Residents prescribed less insulin when patients had T2DM compared to T1DM and medical students prescribed more when the blood sugar crossed the 20mmol/L threshold. We concluded that patient, prescriber, and systems factors ultimately influenced insulin prescribing practices. Overall, we concluded that a successful educational intervention to improve inpatient glycemic control would likely need to address prescribing practices in a prescriber-specific fashion and be followed with a reinforcing intervention. We proposed that medical students and residents may need different teaching methods to address possibly different cognitive processing methods.

abstract: The cytoskeleton is the structural framework of the cell, and plays an important role in cell motility, signalling pathways, and cell behaviour. It is composed of various proteins that form a dynamic network of filaments and tubules to mechanically support the cell. Commonly, cytoskeletal proteins such as β-actin are used as controls or references in many laboratory techniques because they are assumed to remain stable across various conditions. However, most of the research to date has been performed on 2D monolayers of cells adhered to plastic. Recently, 3D cell culture techniques have become more feasible and increasingly popular as they better represent the physiological microenvironment found in the body. As more research shifts from 2D to 3D culture, the changes in cytoskeleton due to culture conditions need to be better characterized. To study gene expression, eleven human cell lines were cultured in 2D and 3D, and reverse-transcriptase quantitative polymerase chain reaction (RT-qPCR) was performed. For analysis, ten control genes were evaluated for stability, and the geometric mean of the three most stable genes was used for normalization. The results show a significant downregulation of several cytoskeletal genes such as β-actin, vimentin, and keratin in 3D compared to 2D. Similarly, key cytoskeletal proteins were also found to be downregulated in 3D using Western blots normalized to total protein. These results demonstrate that the microenvironmental differences between culture conditions can considerably influence cytoskeletal component levels across various cell types. Integrating these findings with the published literature, we suspect that the supra-physiological stiff surface in plastic-adherent culture leads to overexpression of cytoskeletal proteins – presumably also impacting many other pathways and cell behaviour. These findings challenge the assumption that β-actin provides a consistently stable reference gene/protein, emphasize the importance of physiologically relevant culture systems, and highlight the need to select appropriate controls for specific experimental conditions.

abstract: The molecular mechanism of selective ion binding and following modulation of protein function has interested researchers for decades. It is known that cells require metal ions for virtually any imaginable biochemical activity. There are many potential applications of selective ion binding in biology and in bio- and nano-technology, such as cell volume management or proper electric signalling. A particularly important example of selective ion binding can be found in secondary membrane transporters. Secondary transporters are a very large family of integral membrane proteins utilizing electrochemically driven transport of cargo against its concentration gradient. Secondary transporters can be found in every tissue type participating in cell signaling, control of synaptic transmission, cell volume and delivery of key nutrients. With a number of readily available crystal structures, this family of membrane proteins represent an ideal and medically important grounds for studies of selective ion transport. Current understanding of the underlying complex thermodynamics of the ligand or ion binding and the subsequent transport across the cellular membrane is very limited. I used available theoretical methods (Molecular Dynamics, Free Energy and Monte-Carlo simulations) to study different factors, which govern ion binding to secondary transporters. The Free Energy Simulations together with the developed statistical-mechanical model were used to explain the role of the protein matrix in ion binding and selectivity of the sodium-dependent aspartate transporter (GltPh) crystallographic sites Na1 and Na2. I was able to show that only one site is functionally important and capable of selective ion binding. I quantify different factors (cavity size, chemical composition, surrounding protein residues, polarization effects) in defining selective binding. The findings are important for a general design of Na-selective sites with potential applications ranging far beyond single transporter protein. I have extended Grand-Canonical Monte-Carlo simulations to the problem of finding functional ion sites, which may be missing in the low-resolution crystal structures. The problem represents a significant challenge, since many of the functionally important sites have very low binding affinity and thus may be missing in available structures. Theoretical results were blind-tested by experimental work in the collaborating lab of Peter Larsson in Miami. From these computations and experimental measurements a new selective binding site was identified and a transport mechanism has been proposed. The quantum effects have been proposed to be important for selective ion binding to protein sites in secondary transporters. I was the first to develop Quantum Mechanics/Molecular Mechanics (QM/MM) for Free Energy Simulations of selective ion binding to model sites. The method was developed in collaboration with the Dennis Salahub group. A proof-of-principles QM/MM FEP study of ion selectivity with CHARMM-deMon was done in collaboration with Dr. Benoît Roux. This methodological section of my thesis extends the available arsenal to studies of selective binding to membrane proteins.

abstract: Substantial resources are spent annually to reduce phosphorus (P) and nitrogen (N) in entering rivers and to mitigate eutrophication. To achieve a more detailed understanding of the nutrient dynamics in a river reach, the nutrient interactions between different river compartments were examined. A focus of this study was the relationship between the aquatic biomass (macrophytes and epilithic algae) compartment and river flow (including extreme events) and wastewater treatment plant (WWTP) effluent loading. Aquatic biomass growth was strongly affected by both, river flow and WWTP effluent. The mixing process between the effluent and the river influenced the spatial distribution of biomass growth. Biomass recovery after disturbances proceeded relatively quickly but depended on the magnitude of the disturbance. WWTP effluent is a more continuous disturbance than flooding and the relationship is not as straightforward as with flow. Nutrient limitation differed for the different aquatic communities and varied in space and on seasonal and inter-annual time scales. A time lag between effluent loading reductions and macrophyte biomass decline suggested the occurrence of “legacy” sediment stores in the river reach. The other part of the thesis involved quantification of nutrient stores and export in the different river compartments to further examine their interactions. Surficial sediment stored more than 98% of nutrients over an m2 of river bed but surface water was the major driver in nutrient export out of the reach. WWTP effluent mass fluxes showed an impact on both N and P storage, so both nutrients should be considered for effluent quality management of aquatic biomass within the reach studied. Co-limitation of aquatic biomass and differing inter-compartment exchange reactions of the two nutrients further support the statement of considering both N and P in management decisions. Correlation analysis indicated that rivers compartments are intrinsically connected with respect to nutrient fluxes, suggesting that multiple nutrient compartments should be considered when establishing nutrient loading criteria and drawing conclusions about the nutrient limitation of biomass.

abstract:
Reservoir heterogeneities (i.e., lean zones or shale layers) impact the performance of SAGD (steam assisted gravity drainage) processes. The lean zones, which have a water saturation of more than 50%, have been reported by several oil sands fieldsduring the development of oil sand reservoirs in the Athabasca area in western Canada. They reported that the lean zones severely affected the production of SAGD processes. Therefore, an ES-SAGD (expanding solvent SAGD) process has been introduced into this type of reservoir to improve the production performance.
Simulation studies are conducted to investigate the mechanisms of how lean zones influence the two processes by comparing their bottom, middle, and top locations in a reservoir. Moreover, the thickness, location, water saturation of lean zones and reservoir permeability are also investigated to understand the impacts of lean zones further on these processes.  A heterogeneous reservoir model, which contains lean zones, is carried out to study the production performance of the SAGD and ES-SAGD processes.

abstract: During the past decade, there has been an enormous increase in the applications utilizing fully autonomous Unmanned Aerial Vehicles (UAVs). Initially these applications were mostly restricted to military fields like border surveillance, troops enforcement, combat, target, and decoy. More recently they have been extended to many civilian applications, such as firefighting, traffic monitoring, and commercial UAVs. This wide variety of applications makes the UAVs autonomous navigation a challenging task. The UAVs mainly depend on the integration of Global Navigation Satellite Systems (GNSS) and Inertial Navigation System (INS) to navigate autonomously but during the lack or unavailability of the GNSS signals, the UAVs lose their ability to navigate autonomously, due to the massive drift exhibited by the INS when working in dead reckoning mode. GNSS signals may be unavailable due to jamming, spoofing, blockage, or multipath. So, another aiding system must be integrated with the INS, to yield a reliable navigation solution that makes the UAV capable of fulfilling its assigned tasks in a wider range of working conditions. Different sensors and methods were utilized to aid the navigation solution during GNSS outage. Light Detection and Ranging sensor (LiDAR) is one of the main sensors integrated with INS during these periods. The main drawback in the use of LiDAR with small and micro UAVs, is the weight, size, power consumption, and high computational cost. Camera is also considered as a viable solution to aid in navigation during the GNSS outage periods, as it is characterized by features that make it suitable for small and micro UAVs like light weight, small size, and low power consumption, also it provides rich information like features and colors. Visual information provided by a camera can be used for 3D surrounding construction, obstacle avoidance, and position estimation. One of the algorithms mostly used for exploiting camera in UAV navigation is Visual Odometry (VO), which depends on the extraction of the vehicle velocity from matching features of successive images. One of the biggest problems facing the use of a single camera is the loss of scale information. Although this issue can usually be resolved by using stereo/multiple cameras, such a solution is not so effective for small and micro UAVs, because its accuracy mainly depends on the base distance between the cameras, which is necessarily limited in such cases. Regardless of using single/multiple cameras, this sensor performance is still greatly sensitive to certain environmental factors, like light variation or featureless scenes. Radar sensor is much more superior to cameras or LiDAR, due to its immunity to environmental changes. Previously Radar’s weight, size, and power consumption were not adequate for small/micro UAVs. Ultra-Wide Band (UWB) devices have been recently considered in several UAV aided navigation works. Although their great potential to aid the UAV during loss of GNSS signals (absolute positions), due to their limited power, they can only be used in small areas (like indoors). In order to use them outdoors, a huge infrastructure is required, in addition to the availability of beacons with known positions in the flight area is not always guaranteed. So other methods or approaches that do not cost the UAV additional size, weight, cost, or power consumption is essential to achieve a robust and accurate navigation system that is able to fulfill different tasks in all circumstances with acceptable performance. First approach taken during the research is the Vehicle Dynamic Model (VDM) enhanced navigation system. The VDM is the relation between the actuators and vehicle states (accelerations and rotations). We accommodate such approach because it will not cost the UAV any additional weight, size, power, or cost. The main drawback of accommodating this approach is the requirement for a special equipment to estimate the mathematical model parameter of the UAV. Any perturbations during this modelling process will make this approach unable to aid the UAV during GNSS signals outage. In order to avoid such drawback a Machine Learning (ML) approach is adopted to take advantage of the available data from previous flights. Although this VDM- machine learning approach greatly enhanced the navigation solution compared to low-cost INS solution, but the model formed with the aid of the ML approach is specific for this UAV with this configuration, this leads to the second accommodated approach, which is enhanced UAV navigation using micro-Radar as a way to find a more robust aiding approach that’s suitable for most UAVs. Radar as a sensor is more immune to environmental changes (e.g. rain, fog, light conditions), but its weight, size, and power requirement makes it not suitable for such small UAVs. Nowadays micro Radars is available due to the advancement in technologies, which makes it a good candidate to aid small UAVs navigation system during GNSS signals outage. However, low-cost Radars come with more challenges with regards to the extraction of useful information, due to its poor performance, and the existence of large amount of clutters especially at low altitudes. Typical radar targets extractions algorithms are not suitable, especially in our case where the Radar is mounted on board of the UAV, so there is no significant difference between the targets and the background. In order to efficiently extract the targets and estimate the UAV’s velocity a computer vision-based approach is accommodated instead of the typical Radar approaches, our approach consider the output of the radar (range and velocity) as image. This approach greatly enhances the navigation solution during six minutes of complete GNSS signal outage, which reached a 2D RMSE of 5.81 m compared to INS RMSE which reached hundreds of meters. Although micro-Radar system greatly enhance the navigation solution but it’s power requirement, weight, and cost are still a burden on small UAVs. So, the Radar based navigation is followed by other approach that respect all the UAVs limitation and efficiently estimate the UAVs velocity. This final approach is based on manipulating the typical use of two sensors (Hall-effect magnetic sensor, and Mass-flow meter). Both sensors are used to efficiently estimate the velocity of a drone while respecting small drones’ limitations. By utilizing these two sensors the navigation solution is greatly enhanced during GNSS signal outage compared to low-cost INS. These two sensors specifications facilitate the ability to be merged with other sensors like camera or LiDAR to enhance the navigation solution even more.

abstract: Retroelements are mobile elements that are capable of transposing into new loci within genomes via an RNA intermediate. Various types of retroelements have been identified from both eukaryotic and prokaryotic organisms. This dissertation includes four individual projects that focus on using bioinformatic tools to analyse retroelements in bacteria, especially group II introns and diversity-generating retroelements (DGRs). The introductory Chapter I gives an overview of several newly-identified retroelements in eukaryotes and prokaryotes. In Chapter II, a general search for bacterial RTs from the GenBank DNA sequenced database was performed using automated methods. It not only enlarged the collection of bacterial reverse transcriptases (RTs), but also revealed several new classes of RTs. In Chapter III, another automated search was performed to identify group II introns. All predicted introns were automatically folded and then manually refined. Other information, such as multiple copies and non-standard intron organisations, were also identified. Next, all introns were subjected in several analyses in order to depict common properties for each class, such as preferences in target sites and DNA strands. Using this enlarged dataset, Chapter IV aimed to resolve the phylogeny of group II introns and investigate whether the intron-encoded protein (IEP) and RNA portions coevolved. Among trees constructed from various datasets, such as using different sequence masks, smaller sampled subsets or morphological features, the hypothesis that the IEP and RNA coevolved was supported by comparisons among most trees, even though it seemed to be rejected by formal topology tests. Finally, Chapter V compiled and systematically classified the most recent set of DGRs, which can be used as a reliable reference to direct future DGR-related studies and experimental designs.

abstract:
Cell-to-cell interactions are important in determining the electrophysiological behavior of cardiac tissue. In this research, computer modeling is used to investigate the importance of these interactions in two different contexts: 1) how to adjust parameters in single cell models to accurately reproduce tissue behavior, and 2) determining requirements for successful conduction at the interface between different tissue types, specifically from the sinoatrial node (SAN) to the atrium.

Membrane resistance (Rm), the inverse of the slope of the current-voltage (I/V) relationship for a cardiac myocyte, is an important
determinant of electrical cell-to-cell interactions. Experimentally, Rm can be measured by applying a small current and measuring the resulting change in membrane voltage. To investigate the importance of Rm, a multi-objective genetic algorithm approach was developed for enhancing the fitting of action potentials (APs) in single cell models. Rm was fit at several points during the AP along with AP morphology. The results demonstrate that including Rm as a fitting criterion yields improved convergence, reduced variability in parameter estimates,
and improved robustness, while specifically improving the ability of the model to
reproduce tissue behavior.

Bioengineered pacemakers are cellular constructs intended to replace the SAN pacemaker function. The interface between the SAN and atrium appears to have features designed to facilitate conduction. Depending on the species, these features involve gradual transitions  (gradients) in ion channel densities and coupling conductance, or insulating boundaries with
conduction at discrete exit points only. We used simulations to determine the importance of each of these features, with the aim to provide guidance to future development of bioengineered pacemakers. We found that gradients in ionic conductance (specifically ICaL) are required in rabbit SAN. There is narrow range of coupling for which the SAN is able to propagate towards atrium without coupling gradients. In canine SAN, these gradients support conduction. However, gradients are not required, provided conduction from SAN to atrium is restricted to discrete exit points. This suggests two possible strategies for successful conduction at the interface between a bioengineered pacemaker and the atrium: 1) engineer the construct to have appropriate ionic current and intercellular coupling gradients, or 2) functionally insulate a homogeneous construct from the atrium with conduction only at discrete points.

abstract: Colloidal particles can be manipulated under the gradient of an external field to transport them in the system toward desired locations. The motion of colloidal particles resulting from an imposed or self-generated concentration gradient is called diffusiophoresis which has been used in a wide range of applications such as drug delivery, wastewater treatment, and enhanced oil recovery. This phenomenon provides a low-cost and easy portable method to manipulate particles. Previous works investigated the diffusiophoretic motion of non-porous particles in microfluidic channels both experimentally and theoretically. However, the migration of porous particles under the effect of concentration gradient has not been studied experimentally. In this work, we have used a dead-end pore microfluidic channel to explore the diffusiophoretic motion of porous particles. For this purpose, we first study the migration of non-porous particles in the dead-end pore channel with and without the presence of background concentration gradients. Our results indicate a temporary self-generated concentration gradient is generated in the channel resulting from the interfacial interaction of PDMS walls with the ions present in DI water without introducing any background concentration gradient. In the presence of an electrolyte concentration gradient, the relative difference in the ions' diffusivity (β) and particles’ zeta potential are two main effective factors on the diffusiophoretic motion of non-porous particles. In the next section, we study the diffusiophoretic motion of porous particles, and differences in the case of non-porous particles are investigated. In contrast to non-porous particles, porous particles’ migration under the influence of concentration gradient is a function of pore size, surface area, and surface charge density. The surface charge density of porous particles can change significantly because of counterions diffusion into the porous particles which can result in inversion of motion direction. Therefore, the effect of the interior microstructure of colloidal particles is crucial in controlling their diffusiophoretic motion.

abstract: In this study, a non-intrusive multi-view measurement technique is used for tracking ascending air bubbles in a highly-viscous fluid (glycerin) and for tracking the injection of a lower-density mixture into a vertical flow of glycerin. Digital image processing was used to reduce light reflection due to back illumination in the multi-view measurement system. Combinations of convolution kernels and thresholding methods perform boundary detection, light reflection corrections and geometrical parameter measurements in the software ImageJ (Fiji). Receiver Operating Characteristics (ROC) plots based on a True Positive Rate (TPR) analysis are used to statistically quantify the effectiveness of the boundary detection and the light reflection reduction. The experimental scenarios in this study include: an opaque solid sphere ascending in a continuous highly-viscous liquid, air bubbles rising in a continuous highly-viscous liquid (glycerin), air bubbles rising in a stratified fluid with dense glycerin capped by a less dense 50%(w) water-glycerin mixture, and a colored 50%(w) water-glycerin mixture injected into a vertical flow of glycerin. The bubble volume calculation was performed using a “wedge” approximation. Bubble volume had errors as low as -0.3% compared to Ground Truth data. For the experiment of the injection of a colored 50%(w) water-glycerin mixture, light intensity analysis was examined as a method to determine parameters of injected liquid including position, length and segmentation which has the potential to be applied to the study of drag-reducing agent injection into a bulk flow.

abstract: This thesis is an examination of the Mexicanization of the Methodist Episcopal Church. It uses the Methodist newspaper El Abogado Cristiano Ilustrado (The Illustrated Christian Advocate) as its principal source. As the mouthpiece of the Methodist Episcopal Church, El Abogado reported on political, social, cultural, and religious events in Mexico. The Methodists learned, from past experiences, that in order to survive and thrive they had to adapt, evolve, and persevere. They achieved this in Mexico through the process of Mexicanization, using Mexican-born ministers and linking themselves with liberalism, which they viewed as the emerging aspirations of the Mexican nation. The symbiotic relationship between liberalism and Methodism becomes key to understanding how Methodism survived and grew in Mexico. Mexican Liberals desired economic development, modernization, individualism, democracy, anti-clericalism, and nationalism. These tenets closely resembled the ideologies and theologies of the Methodists.

abstract: The control of the flow over a cluster of three rotating cylinders arranged in a triangular configuration (pinball-configuration) is simulated using 2D URANS. The free stream flow impinges onto the front cylinder at Reynolds number of 2054 based on the diameter. Open-loop and closed-loop controls change the flow behavior because the rotating surfaces of the cylinders directly modify the vorticity flux into the wake. For the open-loop control, the leeward cylinders are counter-rotating at a constant rate. In the open-loop control, the strength of the shear layers from the leeward cylinders and the central gap flow change and even reverse as the rotation rate varies. As a result, different and unique flow states were realized. The fluctuation of the flow reaches a minimum at certain rotation ratio (angular velocity of a cylinder non-dimensionalized by free-stream flow velocity). In the closed-loop control, the fluctuating lift of each cylinder is used as a feedback signal to control an oscillatory rotation rate about the mean that is set to match an open-loop configuration. The physical model describing the rotation-induced-lift by oscillatory rotation is developed and reveals a phase lag between 0 to pi from the steady-state-lift. Based on this mechanism, a closed-loop controller is designed such that the rotation-induced-lift partially cancels the lift from the natural vortex shedding. This results in lift attenuation. The closed-loop control is tested on the single cylinder case, revealing that the shear layers are elongated and the strength of the vorticity flux across each shear layer is reduced. The closed-loop control is then applied to the pinball-configuration. The same elongation of the shear layers and the reduction in the strength of vorticity flux are observed. Additionally, the closed-loop control changes the central gap flow, which slightly shifts the flow characteristics accordingly.

abstract: Spontaneous jet ignition, consisting of ignition during early, transient stages of gaseous fuel outflow, like hydrogen, due to a sudden rupture of a high pressure reservoir into atmosphere, was first observed by Wolanski and Wojcicki in 1973. The phenomenon clearly has an important role in hydrogen safety, increasing the risk of explosions. One potential explanation is that the combined effect of heat and mass diffusion at the contact surface, separating the expanded and cooled hydrogen from shocked hence compressed and heated air, leads to ignition. Experimental and numerical evidence shows that the size of the release opening is a crucial parameter with ignition being more likely for larger openings. The structures of the shock and contact surface are multi-dimensional which makes the numerical attempts limited to computational capabilities. However, for constant pressure and planar geometry this process was analyzed by Linan and Crespo in the limit of high activation energy for single step Arrhenius kinetics and unity Lewis number. In the current study, the analysis is extended to account for different fuel mass diffusivities and expansion due to evolution of the shock. The analysis shows that ignition can occur for fuels with higher mass diffusivity like hydrogen, with Lewis number less than unity, but that it does not occur for fuels such as hydrocarbons, with Lewis number greater than unity. In the former case, it also identifies a critical value for expansion, separating situations whereby ignition is inhibited from cases in which ignition will occur.

abstract: This thesis presents novel solutions of altimetry-gravimetry boundary value problems (AGBVPs) with compatibility (smoothness) conditions along the coastline for geoid determination. After an analysis of the state of the art for AGBVPs it was found that a lot of work has already been done in terms of theoretical problem formulation and solution investigation of AGBVPs. The conditions under which the solutions of different AGBVPs exist and are unique have been provided. It has been shown that without additional compatibility conditions along the coastline a solution with higher level of regularity does not exist. This was the starting point of this work and, after three preliminary experiments, it was found that the effect of smoothness along the coast line is significant for cm-geoid determination. Further theoretical investigations by the author resulted in the following achievements and contributions to local and regional determination of the geoid. The theory of spherical pseudo-differential operators (PDOs), spherical wavelets and spherical harmonics was combined for local and regional geoid determination in coastal areas. Using the theory of PDOs, it has been proven that the fixed AGBVP II has a unique solution and different methods applied to solve this problem yield the same solution. It has been shown that the compatibility conditions given by Svensson (1988) are equivalent to the condition that the data and their first and second order gradients coincide with each other along the coastline. It has been proven that PDOs are uniformly Lipschitz α in this case, they can be combined with wavelets that are locally Lipschitz α to increase the regularity (smoothness) of the solution along the coastline. A modified algorithm for reconstruction of a signal using wavelet modulus maxima points is suggested to detect and to smooth existing discrepancies and irregularities along the coastline. Any kind of functionals of disturbing potential is presented in a discrete form, which allows spherical PDOs and wavelets to be applied numerically; even the compatibility conditions are expressed in an explicit form in discrete form as a sum of two functionals described above. Final numerical solution with spherical HShannon wavelets was proposed and conclusions are drawn about its advantages from an application point of view. Finally, as a result of the proposed procedure a smooth transition of the geoid from land to sea can be achieved, which will result in an improved geoid model in coastal areas.

abstract:
Individuals embarking on their journey to become professional social workers often state they feel as if they know nothing upon entering their practice.  Regardless of the number of years critical social workers have practiced, they are also thought to know nothing.
By utilizing a philosophical hermeneutic approach for my research I chose to recognize that new critical social work ideas, theories and practices come from something and somewhere (Moules, 2002).  This research approach involved interviewing six social workers who graduated in the last three years from two social work schools in Canada with a declared critical orientation.  I asked these budding new professionals to describe what happens when they begin working in organizations that may or may not support a critical ideology and how this impacts their practice.
Interpretations of the participant experiences suggest that this nothing is not an empty space.  Instead, it is the in-between space where new critical social work graduates might feel abandoned and unsupported, scrambling for time and resources, and anxious to find the right words.  This is the space where much of their practice involves the frustration of being dismissed because they are both new and unconventional in their thinking.  However, it is also the space in which new critical social work graduates experience the joy of finding a language to express what they already knew before beginning their schooling.  It is the space they sometimes create by insinuating themselves and their ideas into their agencies in a delicate curvilinear manner.  Finally, this nothing is also where new graduates might find solace both in themselves and the Other.

Arguments are made on the need for critical social work practitioners and researchers to provide leadership to human service organizations, educational institutions, and the field in general by researching, supporting, and celebrating those critical practices that do embody the cultural mores and values of our work.

abstract: At the urban scale, creativity is a function of diverse cultural resources, and the creative ethos of urban managers, industries, and residents. This MDP applies the Creative City approach in a conceptual and practical manner utilizing Winnipeg's Exchange District as a case study. As a National Historic Site, the Exchange District is characterized by historic architecture, diverse land uses, cultural organizations, and creative industries. This creative milieu has largely evolved organically. However, recent development pressure has necessitated the need for a planning response that is sympathetic to the area's historical significance and creative character. The Cycle of Urban Creativity served as an analytic tool to evaluate strengths, weaknesses, opportunities, and threats of the Exchange District's current institutions and policy environment relative to fostering creativity. Based on this analysis, recommendations have been provided that address identified weaknesses in the current planning framework, and the capacity of Winnipeg's policy institutions to generate, cultivate, and market creative ideas and projects.

abstract:
Large wall displays have become increasingly widespread, and they can be used in diverse environments to support information sharing and collaboration. Wall displays can also be easily incorporated into multi-display environments, allowing for information exchange between the wall display and personal devices, such as tablets. However, traditional input devices such as the mouse and keyboard present challenges for these types of displays, including problems with window and task management, navigation, as well as selecting individual regions or items. Different techniques should be investigated in order to effectively interact with these large displays.

In this thesis we perform a study comparing the effectiveness of interaction techniques with large wall displays including body-centric techniques (i.e. proxemics and mid-air gestures) and interaction involving secondary devices (i.e. tablets). Participants were given tasks involving different permutations of these interaction techniques, and the results were evaluated using a quantitative measure of task completion time, and qualitative data gathered from post-study interviews and questionnaires. We found that the fastest interaction technique was touch interaction with a tablet, where the tablet was used to control the large wall display. The study also showed that touch selection was most preferred by users in terms of usability.

abstract:
Portfolio optimization is the process of making investment decisions on holding a set of financial assets to meet various criteria. A variety of investment assets around the world make this multi-faceted decision problem very complicated. Econometric and statistical models as well as machine learning and data mining techniques have been used by many researchers and analysts to propose heuristic solutions for portfolio optimization.
However, a literature review shows that the existing models are still not practical as they do not always perform better than even the naïve strategy of investing in all available assets in the market. The methodology proposed in this thesis is an alternative heuristic solution to help investors make stock investment decisions through a semi-automated process. The proposed solution is based on the fact that the investment decision cannot be
fully automated because investors’ preferences that are the key factors in making investment decision, vary among different people. For this purpose, a semi-automated framework called SMPOpt (Stock Market Portfolio Optimizer) has been designed and implemented. In the proposed framework, the goal is to learn from the historical
fundamental analysis of companies to discover the optimum portfolio by considering
investors’ preferences. The Portfolio optimization problem is formulated and broken
down into steps to be able to apply data mining techniques such as Clustering and
Ranking, and Social Network Analysis. Some of these techniques are customized based
on the temporal behaviour of financial datasets. For instance, the ranking algorithm based on Support Vector Machine (SVMRank) is modified and a new algorithm called Time-
Series SVMRank is proposed. A comprehensive experimental study has been conducted
using the real stock exchange market datasets from the past recent decades to evaluate the proposed portfolio optimization solution. The obtained results confirmed the strength of
the proposed methodology.

abstract:
A characterization study was carried out to determine the moisture content, proximate and ultimate compositions, heating value, and thermal weight loss behavior of fourteen different municipal solid wastes (MSW).
An empirical model was developed for the high heating value (HHV) estimation of MSW: HHV (MJ/kg) = 0.350 C + 1.01 H - 0.0826 O, which is expressed in terms of weight percentages on a dry basis of carbon (C), hydrogen (H) and oxygen (O). The validation results suggest that this model was effective in producing accurate outputs that were close to the experimental values.
A series of experiments pyrolysing coffee cups were also performed using zeolite type catalysts. In the presence of Ga/HZSM-5 in the mixed bed reaction, the pyrolysis oil’s effective hydrogen-to-carbon molar ratio (H/Ceff) was markedly increased, from 0.49 to 1.11. Valuable phenolic compounds were observed to be the main species in the pyrolysis oil.

abstract: Increased awareness of the signs of stroke and better stroke management has increased survival rate close to 90% in Canada. However, this means each year close to 4000 Albertans require rehabilitation to re-learn skills for performing daily activities. A major challenge for therapists carrying out rehabilitation is the assessment of motor and sensory functions, especially of the upper extremities. Assessment tools range from therapists using simplistic observer based ordinal scales to more quantitative research-based tools such as the NEOFECT data gloves, using which patients can perform virtual reality-based exercises displayed on a computer screen or using virtual reality headsets. However, existing smart-gloves are marketed towards a clinic, not home, environment. Apart from their high initial $15,000USD cost, they require additional interfacing including costly and precise installation of cameras/base-stations for position tracking in addition to headsets to interact with the virtual reality environments. We propose a prototype of a data glove and arm tracking system with a variety of low-cost, position, orientation, and feedback sensors to supplement clinic assessments, and enable their continued use at home. Preliminary results for gamified rehabilitation exercises to encourage participation in a wider variety of motor and sensory tasks using smart-glove monitoring will be presented. Covid-19 restrictions have limited the ability to evaluate the accuracy and effectiveness of the glove monitoring by comparison to existing assessment approaches for both simplistic and complex therapeutic activities in the clinic. An initial optimization of the real-time capture of smart-glove measurements will initiate our longer term research goal of implementing machine learning models for user’s hand performance evaluation. We believe our prototype has the potential to lead to a new device that could assist therapists, patients, and families by enabling an adjunctive route for monitoring and evaluating stroke rehabilitation and recovery of the post-stroke hand when used in home-based environments.

abstract: Despite the growing urgency for the preservation and revitalization of, and education in Indigenous languages, very little research has been done on effective pedagogical practices that promote strong bilingual development for early learners. This study investigates the effects of an early bilingual play-based intervention among Chakma youngsters in a small rural community of Bangladesh. A case study research approach is adopted to glean deep qualitative insights into various dimensions of the program and its implementation. Photographic evidence, field notes and a reflective journal, interview data, and artefacts of children’s learning constitute the data, analyzed holistically for emergent themes. Three key themes are identified in the findings: (1) the centrality of the teacher, (2) the value of the first language and culture in accounting for a number of outcomes, and (3) the importance of play as a space for engaging children in purposeful, meaningful ‘work’ that promotes the goals of early childhood learning – especially in setting the foundations of language and early literacy learning yet to come. Five promising practices evolve from the data, most important of which are early intervention and a play-based approach that provides a context for culturally responsive practices. Cautions include the transitional nature of the program that threatens the stability of the children’s first language. This may lead to subtractive bilingualism, leaving these children linguistically and, in turn, educationally vulnerable for life.

abstract: The purpose of this research was to examine the readiness of schools within a large urban school district to implement Alberta Education’s inclusive education policy. Through the investigation, the degree to which four factors supporting inclusive education environments were evident in these schools was examined: (a) a shared understanding of inclusive education, (b) inclusive leadership, (c) capacity building, and (d) parent engagement. An evaluative case study (Merriam 1998; 2009) was conducted to examine readiness for inclusive education in randomly selected schools in the district. Data were collected through 7 semi-structured individual interviews and 2 online surveys of staff and parents from participating schools. The data were analyzed using category construction (Merriam, 2009). Five findings emerged from the analysis of the data: (a) definitions of inclusive education vary among stakeholders; (b) ways to support implementation need to be discussed with stakeholders; (c) challenges exist to building staffs’ understanding of inclusive education; (d) decision-making on students’ needs is based on the staff member’s role; and (e) parent input is not being sought in creating an inclusive environment. These findings are significant in four important respects. The study provides evidence that (a) the district is ready to develop inclusive education environments and to facilitate inclusive practices within its schools; (b) stakeholders demonstrate a clear interest in being involved in the process; (c) there is still work to be done by the district in developing a shared understanding of inclusive education; and (d) more effective communication about inclusive education is needed.

abstract: A recent petrophysical formulation states that all the storage mechanisms present in shale reservoirs are best represented by a quintuple porosity system that is further fed by dissolved gas in the solid kerogen. The quintuple porosity system is made up of: 1) adsorbed gas in the pore walls of the organic matter, 2) free gas stored in the inorganic matrix porosity, 3) free gas stored in natural fractures (microfractures and slot porosity), 4) free gas stored in the hydraulic fractures created around the wellbore by the stimulation job, and 5) free gas stored in the organic nanopores. This thesis presents a new material balance methodology for shale gas and shale condensate reservoirs that considers all the aforementioned storage mechanisms. Results lead to the conclusion that ignoring the effects of gas diffusion from kerogen in shale material balance calculations can lead to pessimistic estimates of both OGIP and production forecasts.
