abstract: Spatial and statistical analyses are becoming more commonplace in planning for conservation and land-use programs. I used specific spatial and statistical analyses to examine their potential for answering questions posed by stakeholders in the boreal plain ecoregion regarding the strategic placement of protected areas and forestry cutblocks on the retention of ecological integrity. I found that neither strategic placement nor size significantly affect the retention of ecological integrity within protected areas. Additionally, I found that clustering new forestry cutblocks near existing disturbances did not significantly affect the loss of connectivity, though doubling the expected area of harvest did increase the loss of certain connectivity metrics. The conclusions drawn from this thesis are relevant to landscape planners and conservation managers, but should be paired with the results of biological studies to better represent the reality of complex ecosystems.

abstract: Property boundaries in Alberta that are defined by rivers are subject to the doctrine of accretion. A review of the history and development of this doctrine reveals that it accommodates all types of river channel change, including episodic movement, and that it is the overall progress of the change rather than the moment to moment process that should be considered when addressing whether an event is accretionary or avulsive. A behavioural model developed here for wandering gravel-bed rivers in southern Alberta indicates that change to these rivers is largely episodic and is mainly due to non-overbank peak seasonal flows rather than floods, but that rapid change can occur in response to certain events. Application of the behavioural model and the interpretation of the doctrine of accretion developed here to the 2000 Robertson v Wallace court case supports the judge’s rulings in all three disputed reaches.

abstract: Family presence during resuscitation, while discussed and championed by numerous health care organizations remains an inconsistent practice in many emergency departments, including the one examined in this study. Nurses who participated in this grounded theory study reported support and advocacy for family presence. Family members were regarded a valuable resources for the patient and health care team. The nurses discussed the importance of families being together and working together with the health care team in the resuscitation effort. The social process that emerged from the study was connecting in crisis. Facilitating family presence via policy development was not palatable to the participants. Rather, an overarching belief in the importance of family presence and a situational assessment of resuscitation, patient, family, and team was deemed as necessary prior to family inclusion.

abstract: This study examined the relationship between the Canadian Cognitive Abilities Test (CCAT) and the Wechsler Intelligence Scale for Children - Third Edition (WISC-III) using archival data pertaining to a sample of 279 students with learning difficulties. A significant correlation (r =.43) was found between the CCAT Composite Standard Age Score (SAS) and WISC-III Full Scale IQ. Significant correlations between Verbal and Nonverbal CCAT SASs and WISC-III Verbal and Performance IQs were .35 and .42, respectively. Significant correlations between Verbal, Nonverbal, and Quantitative CCAT SASs and corresponding WISC-111 Index scores were .31, .43, and .31. WISC-111 mean IQ/Index scores were significantly higher than CCAT mean SASs for composite, verbal and nonverbal comparisons, while the CCAT Quantitative SAS mean did not differ significantly from the WISC-III Freedom from Distractibility Index mean. Discrepancies between participants' CCAT and WISC-III composite scores are reported. Directions for future research and implications for practice are discussed.

abstract: In the 21st century there is a need to provide sustainable transportation systems in cities to ensure that they remain centres of innovation, quality of life, and economic development. Public transit is often framed as a high potential mode of sustainable urban travel and while much research has been done on other modes of travel, comprehensive research into its sustainability benefits of public transit has been limited. This thesis first reviews the literature on sustainability and sustainable transport to develop a framework to analyze public transit and then applies the framework to 33 mass transit systems from the USA using the National Transit Database. The Public Transit Sustainable Mobility Analysis Project (PTSMAP) framework developed in this thesis utilizes environmental, economic, social and system effectiveness factors to compare the relative performance of Heavy Rail and Light rail systems while demonstrating how composite sustainability index techniques can be applied to public transit analysis. An application of this framework to a real world transit planning scenario is also presented using data from the TransLink UBC Line Phase 2 study report. Both demonstrations of the PTSMAP framework demonstrate a new way to analyze transit based on sustainability and aid in future research and decision making scenarios.

abstract: Quaternary paleoecological data is still relatively scarce for southwestern Alberta. Accordingly, the objective of this research is to provide information on the post-glacial paleoenvironmental history of the Morley Flats and Kananaskis Valley region of southwestern Alberta. In pursuit of this goal, a radiometrically and tephrachronologically dated core from a small bog near the Yamnuska Centre on the Morley Flats and a radiometrically and tephrachronologically dated lacustrine sediment section from Wedge Lake in the Kananaskis Valley are examined in terms of several paleoecological parameters. Sediment grain size distribution and carbonate content are assessed to provide details of the depositional history for each study site. Palynological analysis is utilized to reconstruct the vegetational history of the region. Fossil molluscan faunal analysis is employed to provide data on environmental variation in the aquatic environment of each study site. In addition, a number of descriptive, preliminary, bivariate and multi-variate statistical techniques are examined in terms of their applicability to the paleoecological data. The empirical interpretation of the results of this research provides a detailed assessment of the post-glacial paleoenvironmental history of the study site. Immediately following deglaciation of the Morley Flats, a tundra-like vegetation was able to colonize the cold and dry region. By at least 10,400 110 B.P. (GSC-2965) the major portion of the Kananaskis Valley, including Wedge Lake, was ice-free and coniferous forests were establishing themselves in the area. A significant trend of climatic amelioration continued from this period until shortly after the deposition of a pyroclastic layer which is tentatively identified as Mazama Tephra. This period of warm and dry conditions was interrupted once by an episode of climatic deterioration which occurred after 9395 + 215 B.P. (GX-6767) and prior to 6600 B.P. Following the deposition of the tephra layer, conditions deteriorated significantly. This episode was followed by a period of renewed climatic amelioration. By 1140 + 70 B.P. (Beta-1282) cool and moist conditions again became prevalent.

abstract: Tumor endothelial marker 8 (TEM8) is highly expressed in tumor vasculature, but not in other endothelial cells including those involved in normal physiological angiogenesis such as wound healing and corpus luteum formation. It has not been reported whether this is due to some intrinsic characteristic of the tumor endothelium or secondary to tumor microenvironmental factors. Screening of TEM8 levels in various cancer and endothelial cell lines used in this project revealed variable transcript level. Changes in level of expression of TEM8 transcripts in human umbilical vein endothelial cells (HUVECs) were examined under the influence of such microenvironmental factors as hypoxia and vascular endothelial growth factor (VEGF), the most potent pro-angiogenic agent. While hypoxia dramatically increased the levels of TEM8 in HUVECs, VEGF seemed to do so only moderately. TEM8 mRNA levels were elevated in HUVECs cocultured with some breast cancer cell lines including, Hs578T, MDA MB 468, MDA MB 453s, MDA MB 231 and MDA MB 436. Contrary to that however, HUVECs co-cultured with the breast cancer cell lines, SKBR3, MCF-7 and BT-474 had no significant changes in TEM8 transcription. Induction of TEM8 was due to direct cell-cell contact rather than to secretion of soluble factors by the tumor cells. Interestingly, the TEM8 inducing breast cancer cell lines have a more aggressive phenotype than the non-inducing group. TEM8 may therefore be a marker of aggressiveness in breast cancer. Overexpression of TEM8 in HUVECs led to more rapid endothelial cell growth and, in contrast down-regulating the gene by AdshRNA resulted in reduced cell growth. Together, these data suggest that endothelial cell expression of TEM8 is a function of the tumor microenvironment. Its upregulation in tumor-associated endothelial cells encourages their growth.

abstract: Competency by design is changing the surgical landscape. Virtual reality simulation appears to be a promising training tool to assist in achieving surgical competency. This study was designed to determine if a boot camp style virtual reality (VR) mastoidectomy drilling course could be developed to improve a novice learner’s mastoidectomy drilling technique. Forty medical students were randomized to a traditional curriculum (control) group or a VR curriculum (intervention) group. Participants performed pre- and post-intervention knowledge testing, and mastoidectomy drilling sessions. Results of the study are an encouraging first step in demonstrating that a VR simulation boot camp course may improve a novice learners’: (i) understanding of the temporal bone anatomy as demonstrated by a significant difference between pre- and post-intervention knowledge testing (p < 0.01), (ii) drilling technique, as demonstrated by a significant difference between pre- and post-intervention drilling testing (p < 0.01), and (iii) ability to recognize dangerous or red flag areas in drilling a temporal bone. Future directions include a recommendation to implement a mastoidectomy VR simulation boot camp course at the annual Canadian Oto-HNS boot camp.

abstract: WiFi has become a widely used medium for delivery of video content. At the same time, there is a proliferation of WiFi capable devices such as mobile phones and portable computers with the capability of consuming video content using WiFi as the access technology. Due to the proliferation of such devices, there is a probability of reduced video Quality of Experience (QoE) due to wireless channel impairments. Wireless channel impairments are a challenging problem for WiFi which uses the license-free ISM band. Even though most devices using the WiFi frequencies will adhere to the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol, there are other devices which do not use this protocol and thus cause interference. Another issue that impairs the wireless channel is reduced Signal to Interference plus Noise Ratio (SINR) due to the access point (AP) to user equipment (UE) distance, or obstruction. Also, when the number of users in a radio range increase, there is an increased probability of collisions. These impairment mechanisms will consequently reduce the video QoE served to a user. The QoE is reduced because of the need for retransmissions, which reduces the channel throughput. Also, because of impairments, the modulation and coding scheme (MCS) selected by the rate adaptation algorithm for WiFi is restricted to combinations which are more robust against these impairments. To improve the QoE served to a user, this research pursues two main approaches: (1) Evaluate methods of estimating QoE for streaming  video (2) Use a Rate Adaptation (RA) algorithm in conjunction with Application Layer Forward Error Correction (AL-FEC) to improve air efficiency. This research utilizes a mathematical model which considers the reduced video resolution during impairments, and effects of stalled video, on the QoE. To reduce the effects of retransmissions, and increase the air efficiency, this study investigates the use of Application Layer Forward Error Correction (AL-FEC), in coordination with Rate Adaptation. FEC schemes are investigated, and a theoretical and experimental evaluation of a AL-FEC scheme is validated, for each MCS selection. Further, a scheme is proposed whereby the wireless channel is regarded as the lowest bandwidth of the path between the video source and consumer. The video source will signal to the WiFi AP for the desired MCS, based on the AL-FEC capabilities, and AL-FEC success rate at the user. The desired MCS is determined by the user and sent via a feedback channel to the video source. The rate adaptation algorithm is evaluated using a Markov model to estimate the gains achieved when using AL-FEC aware Rate Adaptation. Finally an end-to-end algorithm is proposed which selects the optimal AL-FEC scheme based on the current channel conditions. The QoE is compared for critical insight into the gains obtained when using the AL-FEC aware Rate Adaptation Algorithm, and AL-FEC, in order to improve the user Quality of Experience.

abstract: The problem of universals is an extremely old one that has lost none of its original interest or importance. Essentially, the problem is in how to best understand the nature of properties. Realism asserts that properties are abstract entities which are capable of being possessed by several concrete objects found in the world. Moderate nominalism asserts that properties are concrete entities which are only capable of being possessed by single concrete objects. Extreme nominalism simply denies that there are properties. I begin the thesis by arguing that however we think of properties, we must regard the problem of universals as a metaphysical problem. Linguistic solutions offered by people like Frege are entirely inadequate. We cannot make metaphysical headway by considerations of how we speak. In chapter three, I argue that the problem consists in trying to decide how to explain the fact that objects can 'agree' in their attributes. How is it that two apples can both be red? The extreme nominalist denies that there literally are such facts. The moderate nominalist answers that each apple possesses a concrete property and these properties are similar to each other. The realist claims that each apple both possess a numerically identical property. That property cannot, by itself and in its entirety, be locatable in space and time, at least in any obvious sense. Therefore it is an abstract entity. There are no special metaphysical problems with this view. In chapter four I argue that the concept of existence is a primitive one, applicable just as much to abstract entities as to concrete ones. With the three positions understood, I go on to show that we are rationally bound to accept the realist's solution. The extreme nominalist's position is simply implausible and inadequate. Moderate nominalism is less economical and less simple than realism. Realism is simple, economical, coherent, and plausible. Therefore, in the absence of any better theory, we are rationally bound to adopt realism. I conclude the thesis by looking at two historically important and influential theories of universals. The first, from Plato's early dialogues, is an immanent theory of universals. The second, Plato's famous Theory of Forms, is a transcendent one. I do not decide which of these theories is better, but by looking at them we gain a greater understanding of the realist's solution to the problem of universals.

abstract: Incel is a short term used to reference involuntary celibates, a group once created to afford lonely people a place to exist without judgement, but now, co-opted into an ideologically motivated extremist community, existing under a misogynistic belief system (Ging 2019; Kelly and Aunspach 2020). While this community operates primarily within the online realm, their impact through discursive means has proved to be destructive, promoting a violent anti-feminist view through a multitude of open access forums. This thesis explores the content collected from the forum incels.is, utilizing a critical discourse analysis to help identify trends within the acquired data set to explore how users on this site operate as a gendered discursive online community. Disclosed themes throughout the analysis concern the topics of: (1) Gender Essentialism, (2) “Fuel” as an Idealized Masculine Emotional Response, (3) Ambiguous Discourse x Anonymity, and (4) “Saint Elliot”, an incel hero. Through a feminist lens, and informed through existing literature surrounding popular misogyny, platform affordances, and the “manosphere”, I argue that incels.is manipulates their ability to grow and influence the opinions of others, specifically in extremist fashions, by using media platforms and discursive tactics to their advantage (Gotell and Dutton 2016; Massanari 2017; Banet-Weiser 2018).

abstract: Lymnaea stagnalis is a pond snail that has proven useful for studies of learning and memory of aerial respiration. Aerial respiration is an easily quantified behaviour that is controlled by a central pattern generator whose necessity and sufficiency has been directly demonstrated. If snails are exposed to an aversive chemical stimulus ( causes a defensive behaviour without causing permanent harm) before or after conditioning, a training schedule that normally only results in intermediate-term memory, causes longÂterm memory persisting at least 24 hours. A single application of an aversive chemical stressor is also capable of forming long-term memory if the application is contingent with pneumostome opening. Therefore training related to stress or a particularly aversive stimulus is enhanced and, therefore, results in long-term memory. This memory has many of the same characteristics as memory from more extensive training but is, in general, more resistant to manipulation after consolidation.

abstract: Human and murine hosts have a dynamic relationship with the microbes that colonize their bodily surfaces. Shifts in composition of the community of microbes, or their function, are implicated in many chronic and/or inflammatory conditions. There are currently gaps in understanding whether these shifts cause disease phenotypes or are artefacts of changed host conditions due to disease. The ability to tease apart these dynamics by generating bacterial tools that limited bacterial exposure of germ-free mice to a certain time-period was explored in this thesis. I target genes in synthesis pathways of two uniquely-bacterial amino acids, meso-diaminopimelic acid (mDAP) and D-Alanine (D-Ala) in a species of interest, Bacteroides thetaiotaomicron. These amino acids are incorporated into the peptidoglycan, or cell wall, of most bacteria, like B. thetaiotaomicron. This study builds on concepts from a previously developed E. coli strain called HA107, where disruption of these two synthesis pathways generated an auxotrophic mutant that grew if supplemented with said amino acids, however, did not proliferate and persist in germ-free murine gastrointestinal tracts. I designed deletion alleles that would exchange with the functional allele of target genes, and transferred the allelic exchange vector, pExchange, containing the deletion allele into B. thetaiotaomicron through conjugation. The double and triple gene deletion mutants failed to grow when not supplemented with mDAP and D-Ala. This mutation strategy may be adapted to genetically manipulate other notable Bacteroides species. The generated auxotrophic mutants from this study will be useful tools in answering questions regarding how timing or dosage of bacterial exposure affect health or disease outcomes in germ-free mice.

Soil exhibits creep behavior, in which the deformation of soil develops with time at a state of constant effective stress. It is of significance to investigate the creep behavior of soil for geotechnical applications wherein the long-term deformation of soil is concerned. In this study, the aspects of laboratory testing and numerical modelling of soil creep were investigated.

On laboratory testing aspect, a series of one-dimensional and triaxial compression creep tests were performed on clayey and sandy soils, including kaolinite, Ottawa sand, till and oil sands, to investigate the creep behavior of the soils under different conditions.  The dependencies of creep rate on time, stress and inelastic strain were investigated in the creep tests.

On numerical modelling aspect, several issues on modelling soil creep were investigated. It was concluded that the potential for plastic flow is also applicable to describe soil creep from experimental observations and mechanistic pictures. An elasticviscoplastic creep model for soil was proposed to describe soil creep under complex conditions. In the model, the creep rate of soil was formulated as a function of inelastic strain and effective stresses, following the way of Eulerian description of motion. Based on the proposed creep model, a methodology to accelerate creep test was developed. The energy aspect and examples of this methodology were presented as well. Moreover, numerical simulations were performed to investigate the influence of soil creep on the long-term ground settlements above a tunnel in till and on the time-dependent stress redistribution in oil sand due to cavity expansion.

abstract: Preterm infants are a unique population of patients, as prematurity is the leading cause of death in children under 5 years of age, and survivors are extremely challenged during their early and future life 1. Due to prematurity on every system, challenges faced by preterm infant early and later in life include, and are not limited to respiratory, digestive, immune, neurological, and growth-related conditions that can lead to life threatening complications and an increased risk to several diseases later in life 2-4. Probiotic strains are increasingly used in preterm infants due to their potential to reduce mortality and morbidities in this population. However, due to reduced evidence on safety and efficacy, these are not routinely used in extremely premature infants. The infant gut undergoes important developmental stages that are dependent upon the colonization with microorganism, beginning at birth 5.  While it is well established that the premature gut microbiome exhibits profound alterations, the ecological patterns of microbial assembly and succession in preterm infants remained understudied and have only included bacteria. Moreover, it is not well understood how these processes are impacted by probiotics. The goal of my MSc research is to determine if probiotics use changes gut colonization patterns of the gut microbiome during and after treatment, and if the probiotic strains can persist in the gut of extremely premature infants. We showed a successful colonization of probiotics strains in the gut of extremely low birth weight preterm infants in addition to significant ecological changes of bacterial and fungal microbiome during the probiotic’s consumption and up to 6 months after treatment cessation. Our results confirmed that early life colonization with healthy bacteria beneficially impacts the future microbiome in extremely preterm infants.

abstract: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders that occur due to defects in the steroidogenesis pathway within the adrenal glands. CAH is characterized by numerous clinical manifestations resulting from dysregulation of various enzymes in the steroidogenesis pathway. Approximately 90% of CAH cases can be diagnosed by the measurement of serum 17-hydroxyprogesterone alone. However, the quantification of six additional steroids, cortisol, 21-deoxycortisol, 11-deoxycortisol, androstenedione, pregnenolone and dehydroepiandrosterone could significantly improve CAH laboratory diagnosis. Although clinical laboratories predominantly use immunoassays to measure some of the above steroids, these assays are hampered by low specificity due to cross reactivity of antibodies to molecules with similar structures and high cost of antibodies used in the system. As CAH is diagnosed in neonates, using dried blood spot (DBS) as specimen of choice can further improve patient care due to the very small sample volume. This study aimed to develop a more specific and rapid assay to measure seven steroids using liquid chromatography mass spectrometry (LC-MS/MS) in DBS. An optimized DBS sample preparation method was employed without the need of derivatization. A LC-MS/MS assay was developed and optimized using reverse phase-ultra performance liquid chromatography (RP-UPLC) system combined with a triple quadrupole mass spectrometry using positive electrospray ionization (+ESI) mode. Each steroid was quantified using its deuterated or isotopically labelled internal standard. Calibration curve and quality control specimens were prepared in saline-washed erythrocytes mixed with steroid free serum to achieve a 55±1% hematocrit level. Prepared specimens were enriched with predetermined concentrations of the seven steroids and spotted onto Whatman 903® filter papers. The assay was validated according to CLSI analytical guidelines, including limit of detection (LOD) and lower limit of quantification (LLOQ), linearity, precision, and method comparison. The analytical measuring range of the method for all steroids was 2.5 were 0.11-1.8 ng/ml, 0.001-6.4 ng/ml, 1.8–11.5%, and 5.3-13.8%, respectively. This robust and inexpensive assay can be readily implemented in clinical laboratories equipped with LC-MS/MS and can provides superior analytical performance over traditional immunoassays for the diagnosis of CAH.

abstract: Methanotrophs house enzymes capable of methane oxidation, act as a sink for atmospheric methane and play a key role in the global carbon cycle. This study conducted multiple studies on methanotrophs, including: examination of the evolutionary history of copper membrane monooxygenases (CuMMOs), application of methanotrophic communities in protocol design for monitoring methane biofilter systems, and the analyses of single cell genomes containing new CuMMO-encoding genes. CuMMOs are encoded by three genes, usually in an operon of xmoCAB, and oxidize ammonia, methane, and short chain alkanes and alkenes. To examine the evolutionary history of CuMMOs, phylogenetic inferences and compositional genome analyses were applied to a set of 66 genomes. Individual phylogeny of all genes xmoA, xmoB, and xmoC closely matched in almost all genomes, indicating this operon evolved as a unit. However in Verrucomicrobia pmoB has a distinct phylogeny from pmoA and pmoC. The gammaproteobacteria AMO (Nitrosococcus spp.), the gammaproteobacterial Pxm, the thaumarcheotal AMO and the NC10 pMMO showed little or no compositional bias in the xmo operon indicating similar compositional biases to its genome. Based on the analysis, possible lateral gene transfer events of xmoCAB genes were predicted. The nitrifying bacterium Nitrosococcus postulated as the donor of pmoCAB to both the alpha- and gammaproteobacterial methanotrophs. To design a monitoring protocol that would allow a simple, cost effective and accurate estimation of whether a methane biofilter is operating efficiently, microcosms using compost as a biofilter material were tested via growth and starvation experiments for long periods. Analysis of 16S rRNA gene sequences suggested that non-methanotrophic methylotrophic bacteria belonging the family Methylophilaceae showed a rapid response to biofilter methane oxidation activity and may be a good monitoring target. A monitoring system based on these “methanotroph-associated methylotrophs” is proposed and a ratio of Methylophilaceae to Methylococcaceae of 0.35 was related to high methane activity and 0.1 to low activity. Novel copper membrane monooxygenase encoding operons (xmoCAB) were detected while screening metagenomes obtained from oil sands environments. Quantitative PCR assays were developed for detection of xmoCAB genes in methane, ethane and propane enrichment cultures from environmental samples. Single cell genomes were sequenced from the xmoCAB positive sorted cells of a propane enrichment culture. Screening the genomes identified Polaromonas and Rhodoferax as containing multiple xmoCAB operons. Potential propane oxidation pathways were predicted based on enzymes present in single cell genomes of these two genera.

abstract:
An important goal in elementary mathematics classrooms is for teachers to employ instructional practices that engage students to develop sustainable and deep conceptual mathematics understanding. In preservice education, this often requires transforming student teachers’ beliefs about teaching mathematics, and their knowledge of mathematics content and pedagogy. This study involved preservice teachers from two mathematics methods courses and specifically examined teaching and learning experiences that contributed to their development in: 1) content knowledge, 2) teacher efficacy, and 3) pedagogy. Building capacity across these three constructs was considered significant in the preservice mathematics courses. This research focused on identifying the factors which influenced students’ development in these three constructs with the view to enhance preservice mathematics programs.
    The theoretical framework for this research was underpinned by several theories: mathematical knowledge for teaching theory, self-efficacy theory, constructivist learning theory, and adult learning theory. These selected theories were deemed to be highly pertinent to the phenomena of preservice mathematics teacher development and drew upon a range of theorists such as: Ball, Thames, and Phelps, 2008; Bandura, 1986; Dewey, 1938; Knowles, 1984; Mezirow, 1991; Piaget, 1952; and Vygotsky, 1978.
    Through a mixed methods approach, this study utilized quantitative data related to student teachers’ mathematics content knowledge, teacher efficacy, and anxiety. The qualitative data included student teachers’ journals, interviews, and the researcher-instructor’s journals. The five broad themes that emerged from the converged data were: 1) importance of the instructor’s role in mathematics teacher development; 2) problem solving to support conceptual understanding; 3) building confidence as a mathematics teacher; 4) working towards constructivist pedagogy; and 5) classroom management.
    Two models were developed from the findings in this study. Model one highlights the differentiating mathematics needs of preservice teachers and ways to support their needs prior to the start of their teacher education program; and model two addresses conceptualizations of coherence and how this can be achieved across the dimensions of mathematics preservice education. These models and this study’s significant findings will be of interest to those seeking to enhance preservice elementary mathematics teacher education through building coherence and implementing strategies to meet the varying backgrounds of student teachers.

abstract:
Sub-pore scale modeling of flow in porous media is gaining momentum. The concept of Digital Core Analysis deals with measurements of virtual core and the purpose of such modeling is to replace conventional and special core analysis when the latter are not feasible. One of the challenging concepts in micro-scale simulation of porous media is consideration of phase change phenomena. Mass and heat transfer equations have to be considered simultaneously to capture complexities involved in the evaporation and condensation processes. Therefore, a numerical scheme based on the Volume-of-Fluid method was implemented using the OpenFOAM open-source CFD package along with four phase change models.
The aforementioned approach is extended in the modeling of phase change within a porous medium. Surface roughness is introduced by the incorporation of wedges of variable density and amplitude on the grain surface. A further introduced complication is that the individual grains are of different mineralogy and thus of different wettability. It is observed that steam condenses first in the smallest of wedges, which act as nucleation sites. A condensate film was generated around high roughness density areas and the amount of condensate being generated in the roughened medium was significantly larger than the generated condensate in smooth surface.  Water spreads on water-wet surfaces. Snap-off is observed in several cases leading to temporary trapping of vapor. Grid size effects are also addressed.
The application of this modeling effort is the condensation of steam in thermal recovery methods. The effect of temperature on bitumen viscosity reduction during steam flooding operation as well as steam condensation, trapping of the oil behind the steam front and finally countercurrent flow of steam and condensate-bitumen due to gravity effects.

abstract: Precise information about the temporal mode of  optical states is crucial for optimizing their interaction efficiency between themselves and/or with matter in various quantum communication devices. Here we propose and experimentally demonstrate a method of determining both the real and imaginary components of a single photon's temporal density matrix by measuring the autocorrelation function of the photocurrent from a balanced homodyne detector at multiple local oscillator frequencies. We lay the theoretical foundation for our work and describe the experimental methods involved in detail. We show the results of testing our method on single photons heralded from bi-photons generated via four-wave mixing in an atomic vapor. We develop an appropriate theoretical model for our experimental settings and describe the involved calculations explicitly. The obtained experimental results show excellent agreement with theoretical predictions for the various settings involved.

abstract:
The objective of this research was to explore strategic options for alternative boundary dispute resolution (ABDR) mechanisms that improve non-treaty boundary determination for First Nations in Canada by rebalancing the power relationships with government to relieve the comprehensive claims backlog.
The comprehensive claims process concerns the negotiation of modern treaties between First Nations and the Canadian government and includes boundary determination.
Boundary determination needs to balance the land interests of Aboriginal Peoples and government. This is informed by the seminal case, Tsilhqot’in Nation v. British Columbia, [2014] SCC 44, where the Supreme Court of Canada said that traditional use informed boundary determination and relied on non-treaty boundary determination to grant Aboriginal title within Canada’s cadastre for the first time.
A review of the literature found that a Canadian Alternative Boundary Dispute Resolution (ABDR) mechanism may assist boundary determination in comprehensive claims if it is structured to (i) include expert panels, (ii) apply both common law and Indigenous legal principles, and (iii) innovate by accommodating Aboriginal legal boundary principals. A graduated spectrum of diminishing rights was also described as a framework for Aboriginal traditional use lands within ABDR.
The method of Barry (1999) that coupled induction with a descriptive narrative method was adapted to this research using twenty-two semi-structured interviews of seven First Nations in Canada and fifteen non-Aboriginal Canadians familiar with non-treaty boundary determination. Responses were coded into themes and ranked using an ordinal scale to support interpretation of the interview data and triangulation between the participants.
It was found that a quasi-judicial framework may be established that is only reviewable by superior courts of appeal by developing a novel ABDR mechanism that empanels experts on Aboriginal law and issues who are culturally sensitive to Aboriginal Peoples. It should also utilize land surveyors in the field to walk the boundaries. By induction, it also found that a quasi-judicial ABDR mechanism may be viable within the Surveyor General Branch if this department is moved out of Natural Resources Canada where it could be expected to have greater autonomy and perceived independence by Aboriginal Peoples.

abstract: The goal of a biometric recognition system is to make a human-like decision on individuals’ identity by recognizing their physiological and/or behavioral traits. Nevertheless, decision-making process by either a human or a biometric recognition system can be highly complicated due to low quality of data or an uncertain environment. Human brain has an advantage over computer system due to its ability to perform a massive parallel processing of auxiliary information such as visual cues, cognitive and social interactions, contextual and spatio-temporal data. Similarly to a human brain, social behavioral cues can aid the reliable decision-making of an automated biometric system. Being an integral part of human behavior, social interactions are likely to possess unique behavioral patterns. However, the significance of social behavior for automated user recognition has been noted in the scientific community only recently. In this doctoral thesis, a novel person recognition approach is presented that relies on the knowledge of individuals’ social behavior in order to enhance the performance of a traditional biometric system. The social behavioral information of individuals’ has been mined from an Online Social Network (OSN) and fused with traditional face and ear biometrics. This research identified a set of Social Behavioral Biometric (SBB) features from the online social information and proposed a framework to utilize these features for an automated person recognition for the first time. Extensive experiments confirm that human social behavior expressed through OSN can provide a unique insight onto person recognition. Performance of the proposed multimodal approach has been evaluated to determine the effectiveness of fusing social behavioral information. Experimental results on virtual and semi-real databases demonstrate significant performance gain in the proposed method over traditional biometric system. This doctoral research contributes to an emerging research direction in biometric domain as well as opens new frontier of studying social behavior in virtual domain.

abstract: Emilio ‘Indio’ Fernández (1904-1986) was a prominent film director of the Golden Age of Mexican Cinema (1936-1956). Central to his work was the representation of the Mexican national identity, which was expressed through the narrative and visual elements of his films. Music was also central  in Emilio Fernández’s work, but the soundtracks have only been passingly addressed by the critical literature devoted to Fernández's films. This thesis attempts to address this issue through a discussion of the role of music in three movies that span Fernández’s main nationalistic concerns: the Mexican revolution, the life of the Mexico's indigenous people, and social life in Mexico's urban centers. In chapter one this thesis examines the historical events that led Mexico to become a leading Spanish-language film producer during the period between 1936 and 1956 — known familiarly as the Golden Age of Mexican Cinema. Chapter two is devoted to Emilio Fernández and his ideas of ‘national cinema,’ as well as the director’s relationship with the composers (Francisco Dominguez and Antonio Diaz Conde) that wrote the music for some of the most significant films of his career. Chapter three discusses the music in Flor Silvestre (1943),  a film devoted to the cinematic representation of the Mexican revolution. Chapter four is dedicated to the music in María Candelaria (1944) — a film in which Emilio Fernández portrays a stylized image of the Mexican indigenous people. Finally, Chapter five explores the musical life of Mexico City in the 1940s as presented in the movie Salón México (1948). This thesis traces the origin of the musical genres included in the selected movies. This is to evaluate how these genres are representative of the Mexican musical traditions. In addition, this thesis explores the dramatic function of both diegetic (onscreen) and non-diegetic (background) music in relation to the narrative and visual elements of the films.

abstract: The pollution of groundwater as a result of intensive agriculture has become a major concern for rural areas. This thesis examines the relative cost-effectiveness of implementing a buy and lease policy and a nitrogen standard policy as a means of reducing nitrate concentration from agricultural sources at the Thornton production wells, located in the County of Oxford, Ontario. In order to find the minimum social cost of implementing these two policies, two models are developed, the buy and lease model and the nitrogen standard model. Both models involve a linear programming technique. After simulating each policy for the Thornton Well Field and applying the two models it is evident that the buy and lease policy is more cost-effective. The results also show how optimal implementation of each policy reflects the agricultural productivity of various fields along with physical parameters of the aquifer, such as time of travel and infiltration rates.

abstract: Intestinal roundworms cause chronic debilitating disease in humans and livestock. The lack of vaccines and the emerging drug resistance only increase the need to better understand worm-host interactions. H. polygyrus larvae induce an intestinal granuloma response whereby immune cells, mostly alternatively activated macrophages and eosinophils, accumulate around the tissue encysted parasites. In vitro, these cells and antibodies immobilize, damage/kill worms within the granuloma. This is yet to be confirmed in vivo. We focused on understanding: the mechanisms underlying effective granulomas (chapter 1), the role of resistin like molecule (RELM) alpha, a protein shown to downregulate Th2 immunity (chapter 2), and eosinophils, an enigmatic cell type whose role in anti-worm immunity remains controversial (chapter 3). C57Bl/6 mice are susceptible to H. polygyrus infection. However, mice that are infected using a more natural approach (multiple low doses – (trickle) - as opposed to one large dose (bolus)), had fewer adult worms with more granulomas. Their granulomas had decreased RELM- expression, increased anti-parasitic RELM- and fibrotic gene expression as well as a stronger IgG1 accumulation. In the absence of RELM-, granulomas from trickle-infected mice remained more protective, with upregulated genes involved in eosinophil chemotaxis. Despite this increased eosinophil recruitment, the granulomas from RELM--/- mice were not as protective as those from wild type animals highlighting the need for RELM- for maximal granuloma efficiency. In WT mice, we found eosinophils accumulated around tissue encysted H. polygyrus during acute and chronic infections. The spleen, mesenteric lymph nodes and Peyer’s patches (PP) had increased eosinophilia, with resident and recruited eosinophil surface markers. In addition, eosinophils accumulated around the protozoan parasite Toxoplasma gondii indicating that intestinal eosinophils may represent a key cell type in immunity to different types of incoming parasites. T. gondii infection did not increase eosinophil numbers in the intestine or PP. However, eosinophils showed an inflammatory phenotype marked by increased MHC II and CD101 expression. These findings highlight that the granuloma is a key, complex site of anti-worm immunity and that trickle infection models provide us with a novel tool to study the mechanisms at play within granulomas.

abstract: The topic of humans altered and improved through advanced cyborg technology—technology that amalgamates animal and machine—has long been of interest in science fiction, gaining popularity in most Western countries and Japan. This paper examines two graphic novel series, Robert Venditti’s The Surrogates and Yukito Kishiro’s Battle Angel Alita, in relation to cyborg humans and the theoretical concept of posthumanism, defined as a state that transcends the limitations of human existence with the help of cutting-edge technologies. The posthuman theory of Donna Haraway suggests that the cyborg has the potential to change humanity for the better, to challenge essentialist dichotomies and harmful identity politics. However, theorists like Katherine Hayles warn about the dangers inherent in technologies that allow humanity to “master” the body—and mortality—completely. This paper critically examines both perspectives and, ultimately, the viability of a utopic posthuman state.

abstract: Several industrial processes involve the precipitation, aggregation, and settling of asphaltenes from solvent diluted bitumen. Models and data that include the effect of solvent type, concentration, shear, and contact time on asphaltene precipitation and settling are required to design and optimize these processes but are lacking or are specific for conventional oils. In this thesis, the kinetics of asphaltene precipitation, aggregation and settling were investigated for n-heptane and n-pentane diluted bitumens at ambient conditions. The onset and amount of precipitation were measured in air and nitrogen. The size distribution, fractal dimension, and settling rates of the aggregates were also measured. Asphaltene aggregates were found to be fused fractal structures that are insensitive to shear once formed. A semi-empirical correlation for their fractal dimension was proposed. Asphaltene precipitation in a nitrogen atmosphere was found to be time-dependent but reached an apparent equilibrium after tens of hours. A previously developed population balance model was adapted to include both nucleation and flocculation mechanisms and was tuned to match both precipitation amounts and aggregate sizes. Asphaltene precipitation in air did not reach an equilibrium likely because oxygen altered the asphaltenes. An oxidation rate term was introduced into the population balance model to match the precipitation data in air. The proposed model matched both yields and aggregate sizes over time for several bitumens and conventional oils to within 15% in nitrogen and 20% in air. Asphaltene aggregates were found to have an approximately log normal size distribution but settled as a zone; that is, all aggregates settled at the same rate. The average aggregate size and fractal dimension reached a maximum at an n-alkane content of approximately 75 wt%. Settling rates are a function of the aggregate size and fractal dimension and reached a maximum at approximately the same n-alkane content. The settling rates were modeled with Stokes’ law modified to include the fractal dimension of the aggregates and using the Sauter mean diameter for all aggregates. The model matched settling rates to within 20% of the maximum settling rate.

abstract:
Botulinum toxin type-A (BTX-A) injections have become a common treatment modality for a
variety of neuromuscular disorders with the primary aim to relax spastic muscles, for example, in
children with cerebral palsy, or following a stroke. Once injected, BTX-A prevents acetylcholine
release at the motor nerve endings, thereby producing a dose-dependent muscle paralysis.
Despite an exponential growth of patients receiving BTX-A treatment, there has been no
systematic evaluation of the effects of the toxin on target and non-target muscles. Therefore, the
general purpose of this PhD project was to evaluate muscle mass, strength, and contractile
material in injected and contralateral non-injected quadriceps muscles of New Zealand White
(NZW) rabbits following single and repeated BTX-A injections. Muscle mass was assessed as
the wet weight of muscles following sacrifice, strength was assessed by stimulating the knee
extensor muscles via femoral nerve stimulation and quantifying the knee extensor force, the
amount of contractile material was quantified histologically.
We found that six-monthly BTX-A injections into the quadriceps caused substantial muscle
weakness, atrophy, and contractile material loss in the injected and the contralateral non-injected
muscles. Adding direct electrical muscle stimulation during the BTX-A injection help to
alleviate muscle mass, strength and contractile material loss and the injected and contralateralnon
injected muscles, and finally, BTX-A injections had long lasting effects that were not fully
recovered at six months following the end of the injection protocol.
We concluded from the results of this series of studies that BTX-A treatment resulted in adverse
effects on the injected and contralateral non-injected musculature up to six months following the
iii
injection protocol. Future studies should be aimed at identifying strategies that minimize/prevent
adverse effects of BTX-A injections on target and non-target muscles.

abstract: This document details a five-part research project inspired by the divide between the sciences and theatre. It begins with research into this divide, historical examples of connections between science and theatre, and strategies for reconnecting science and theatre. Next is the analysis of interviews with professionals working at this nexus, conducted by the researcher, and a workshop built to test strategies for exciting artists about science. The fourth section details the devising of a plant science and mycology inspired theatre production designed to re-excite people about the natural world and increase their interest in interdisciplinary work. The final section analyses feedback from the cast, workshop participants, and audience members to determine the impact of the process, workshop, and production, and to identify useful strategies for science communication through theatre. Though the divide between theatre and science is understandable, there is incredible potential in connecting these disparate disciplines. When a powerful communication tool like theatre is combined with a scientific subject that encourages critical thinking, the product can inspire deeper thought about the world around us and encourage deeper connections with that world and its inhabitants.

abstract: Nonstationary wavelet simulation and estimation methods are closely related to nonstationary seismic modeling and nonstationary deconvolution. Conventional wavelet estimation and deconvolution do not deal with the nonstationarity of the wavelet. This thesis begins with an investigation of the methods for nonstationary wavelet simulation that can be used to generate realistic synthetic seismograms. Then this thesis examines methods of wavelet estimation using I-D attenuated synthetic data and real data. These estimation approaches are the basis for Wiener deconvolution (time domain), Wiener deconvolution (frequency domain), and Gabor deconvolution. For comparison, the wavelet is also estimated from downgoing waves isolated from a VSP experiment which gives direct recordings of the nonstationary wavelet. Finally, a new approach is provided for evaluating the accuracy of the nonstationary wavelet estimates by the VSP downgoing wavelets. This result shows that the wavelets estimated from Gabor deconvolution are more stable and closer to the wavelet estimates from VSP data than those from multi-window Wiener and frequency-domain spiking deconvolution.

abstract: In the past decade, Western Canada has seen the emergence of an unconventional resource known as tight oil. In 2017, oil production from this resource reached 430 thousand barrels per day, accounting for approximately 10% of all Canadian crude produced. Despite rapid development, the environmental impacts associated with the production and use of this resource are still being understood. Production is spread widely across multiple provinces, varying in production characteristics and facing unique environmental and operational challenges. The objective of this thesis is to investigate the environmental impacts associated with the production and use of Western Canadian tight oil. Three environmental impacts are considered in the comparison of thirteen different tight oil formations; life cycle ‘well to wheels’ (WTW) greenhouse gas (GHG) emissions intensity, freshwater use and induced seismicity. The impacts are assessed spatially and the trade-offs between the formations are considered. An attempt is made to address the drawbacks of previous crude oil life cycle assessments (LCAs), through the consideration of multiple impacts and a rigorous evaluation of resource variability. A tool is developed using public data, enabling the estimation of upstream emissions intensities for a broad range of Canadian resources down to the individual producing well. Annual emissions from tight oil production are forecast, and the influence of uncertain factors such as economics, regulations and sweet spot targeting (targeting different areas of the resource) are investigated. The results show the complex relationships between physical characteristics, operational characteristics and environmental performance, and demonstrate the need for more comprehensive modelling to facilitate better decision-making in the development of Canadian resources.

abstract: Accused persons in Canada who are found “not criminally responsible” (NCR) on account of mental disorder are excused from criminal liability, as they have no moral blameworthiness for their action leading to the criminal charge. However, persons found NCR are not acquitted. They are transferred to the jurisdiction of a provincial review board, where they remain under supervision and conditions unless or until they are found to not pose a significant threat to the safety of the public. NCR accused may be detained in hospital during their review board supervision, or face other deprivations of liberties. There is no maximum period that NCR accused may be under the jurisdiction of a review board. Accordingly, a person found NCR could be subject to deprivations of liberty for the rest of their lives, even if found NCR on a relatively minor offence. This can be a disincentive for accused persons considering the NCR verdict, particularly when they would face a finite, non-custodial or short custodial sentence on conviction. This thesis considers the need for limiting mechanisms on the duration of NCR dispositions. First, the options for proceeding through the criminal justice system that may be available to accused persons with mental disabilities are reviewed. The history of the NCR verdict and NCR dispositions is then considered, including legal and legislative changes that have culminated in the current disposition provisions. This is then contrasted with empirical studies regarding NCR dispositions and the impact of such dispositions on NCR accused. The contrast allows for a comparison of the “law-on-the-books” to the “law-in-action”. Emphasis is placed on the discrepancy between the stated goals of NCR dispositions, which are allegedly not punitive because NCR accused are not morally blameworthy, and the potential punitive effect of indefinite dispositions. This thesis asserts that additional limiting mechanisms are required on disposition provisions. Capping provisions are the central limiting mechanism analyzed and recommended. A mandatory "verdict inquiry” when an accused person applies for, or consents to, an NCR verdict is also recommended. The thesis concludes with proposed next steps and topics for further discussion.

abstract: Proteoglycan-4 (PRG4) and hyaluronan (HA) are biological macromolecules with varied and diverse functions distributed throughout the body. In synovial fluid (SF), PRG4 and HA provide independent and synergistic contributions to tissue health and cartilage boundary lubrication. The biological consequences of joint injury or disease such as osteoarthritis (OA) may include altered concentration, structure, and function of PRG4 and HA, leading to degraded SF quality and function, changes which are not fully understood. Furthermore, the effects of joint disease on circulating (serum) PRG4 and HA, both of unknown origin and function in blood, requires clarification. Monitoring changes to PRG4 and HA to elucidate the effects on SF and serum may facilitate the development of therapeutics, biomarkers, or novel biomaterials to restore joint health and function. The objectives of this thesis were to 1) investigate clinically relevant changes to PRG4 and HA composition in SF and serum, and SF biomechanical function from equine cases of joint disease and injury, 2) to investigate the effect of exercise on equine serum PRG4, and 3) to characterize the effect of recombinant human PRG4 (rhPRG4) integration on the biomechanical, architectural, and biological aspects of a collagen-based scaffold for cartilage repair. A combination of novel and previously characterized biochemical and biomechanical techniques were used to evaluate SF and serum composition, the lubricating ability of SF and tissue-engineered collagen-scaffolds, and the in vitro bioactivity of rhPRG4-integrated collagen-scaffolds. The composition of equine SF changed in acute joint injury compared to SF from normal horses. Both PRG4 concentration and HA molecular weight were altered, with decreased SF viscosity, yet no associated detectable effects on serum PRG4. The concentration of serum PRG4 in a group of racehorses decreased significantly five minutes post-exercise, perhaps clearing from the circulation. Hence, serum PRG4 and HA concentrations alone may not be useful biomarkers for equine joint disease. rhPRG4-integrated scaffolds had enhanced lubricating properties, a highly porous architecture, and supported cell infiltration and growth across most concentrations tested. Collectively these results indicate that PRG4 is an essential lubricant, an indicator for injury, and a promising therapeutic for integration within cartilage repair biomaterials.

This thesis develops a combined GPS L1, L2C and L5 KF based tracking loop by
exploiting the dispersive nature of the ionosphere and signal structure of the
GPS signals. This results in a robust tracking loop suitable for a scintillation
monitoring receiver. It also incorporates an adaptive algorithm that has
adaptive bandwidth depending on scintillation level. Performance of combined
KF based tracking algorithm compared with that of single frequency KF based
tracking algorithm for both adaptive and non-adaptive cases are analysed and
compared.
A semi-analytic model is used to analyze the effect of scintillation on the
tracking loop to perform faster and provide a reliable platform for analyzing the
scintillation effects on the receiver performance. Results obtained from
simulation data and real data show better performance for the adaptive multifrequency
KF based tracking loop than that of the single frequency KF based
tracking loop and the non-adaptive KF tracking loop.

abstract: Given evolving technological advances, GPS technology has increasingly been applied to domestic violence situations. In Central Alberta, a project was undertaken to equip high-risk domestic violence offenders with GPS tracking technologies. In addition to this, a GPS tracking device, equipped with an alert button, has also been made available to victims of domestic violence. This study examined perceptions of risk and coping mechanisms among victims of domestic violence, with a specific focus on GPS technology and the nature of victim protection in the context of technologies proposed to increase perceptions of safety in circumstances of domestic violence. Overall, the study found that the devices did not appear to create a false sense of security, but were rather seen as another tool the women were able to use in order to manage their risk of abuse.

abstract: We live in a postmodern world, characterized by rapid dissemination of information through technology, the decline of the factory system, decentralized decision-making, and workplace intensification (Hargreaves, 1994). In such a context, so different from the modern industrial world, some question the relevance of unions (Verma & Kochan, 2004). In this thesis, I argue that unions-and teacher unions in particular-are not only relevant in this postmodern world, but crucial. As the world adapts to shifts in global power, immigration, work, and resource allocation (Canton, 2006; Friedman, 2007; Gratton, 2011; OECD, 2008; Quinlan, 2011), and as those shifts influence education (Toole & Seashore Louis, 2002), teacher unions are needed to meet both the traditional industrial and professional interests of their membership and also to address broader democratic and social justice issues affecting those within and beyond their membership. However, to meet those demands and to be viable organizations in today's postmodern world, teacher unions must be confident.  This exploratory multiple case study, conducted in the Interpretive tradition, is based on Rosabeth Moss Kanter' s (2006) Theory of Confidence, which asserts that confident or winning organizations exhibit or promote accountability, collaboration, and initiative. The study sought to determine the extent to which the members of one teacher union in Ontario, Canada-the Ontario English Catholic Teachers Association (OECTA)-perceived their union as confident. Data were collected through observations; an examination of the documents on OECTA's website; and interviews with thirty OECTA members, including provincial executives, local executives, staff representatives, and rank-and-file members. The results of the study indicated that OECT A generally demonstrates accountability, collaboration, and initiative, and thus is a confident organization; however, like many organizations, it can improve in these areas in the short, mid, and long term.

abstract: The use of polymer flooding as an enhanced oil recovery (EOR) method to achieve a more uniform volumetric sweep of the reservoir has increased over the past ten years. However, chemical, thermal and mechanical degradation of the polymers reduce their viscosity, which affects their performance. Nanoparticles (NPs) have been proposed as additives to make polymer flooding economical in challenging reservoirs or harsh conditions. NPs in polymer solutions (nanopolymer sols) are, nevertheless, an emerging class of materials. A more structured approach is needed to properly understand the physical and chemical interactions between the NPs and the polymer solutions. In the first stage of this study, nanopolymer sols were prepared by adding silicon oxide (SiO2), aluminium oxide (Al2O3), and titanium oxide (TiO2) NPs, and in-situ prepared iron hydroxide (Fe(OH)3) NPs to polymer solutions of partially hydrolyzed polyacrylamide (HPAM) and xanthan gum (XG). In the second stage, the surface of the NPs were modified by chemical grafting with carboxylic acids, silanes, and polyacrylamide. The modified NPs were characterized using transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and energy-dispersive X-ray spectroscopy (EDX). All prepared nanopolymer sols were evaluated to determine their effectiveness in improving heavy oil recovery by studying their rheological properties at different shear rates and NP concentrations, colloidal stability, interfacial tension (IFT), and contact angle.  Finally, a selected set of nanopolymer sols were evaluated by conducting oil recovery tests in a Hele-Shaw cell and linear sand-packs. According to the observations in Hele-Shaw cell, the fingering patterns of XG and XG/1.0-2.0wt% of NPs were characterized by the formation of branched structures (at earlier growth stage) which by merging and coalescing formed stable interfaces. However, HPAM and HPAM/1.0-2.0wt% of NPs exhibited different fingering patterns with tip-splitting or suppressed tip-splitting and side-branching. Only XG polymer solutions, modified with 1.0 and 2.0 wt.% of unmodified NPs improved areal sweep efficiency between 5 - 7%. For the displacements in the linear sand-pack, the NP concentration was reduced from 1.0 wt.% to 0.2 wt.% to improve the transport of the NPs into the porous media. The incorporation of 0.2 wt.% of unmodified and modified SiO2 NPs increased the viscosity of the XG solution at all salinities, whereas the high XG adsorption onto the surface of the Fe(OH)3, Al2O3, and TiO2 NPs reduced the viscosity. Adsorption of the NPs, SDS molecules, NP-SDS complexes and NP-polymer-SDS complexes onto the oil-nanofluid interface reduced the IFT of the XG solutions. Also, the NPs changed the wettability of the glass from oil-wet to intermediate-wet. The NPs increased the cumulative oil recovery of the salt-free XG solution between 3 and 9%. At 1.0 wt% NaCl, the NPs reduced oil recovery by XG solution between 5-12%, except for Fe(OH)3 and TiO2 NPs. These NPs increased the oil recovery between 2-3% by virtue of reduced polymer adsorption caused by the alkalinity of these nanopolymer sols. Additionally, the surface properties of SiO2, TiO2 and Al2O3 NPs were improved by polymer grafting. The HPAM nanopolymer sols exhibited lower IFT and ability to alter the wettability of the glass substrate from oil-wet to intermediate-wet. The thickening behavior of the HPAM solution was improved by the addition of 0.2 and 0.4 wt % TiO2-PAM NPs at all salinities. The displacement experiments demonstrated that the addition of TiO2-PAM NPs increased the cumulative oil recovery by 2% while the addition of SiO2-PAM and Al2O3-PAM NPs reduced it between 3 and 7% at 1.0 wt.% NaCl. At higher concentration, TiO2-PAM NPs can enhance oil recovery between 5 and 7%, independent of the salinity. It was also observed that the surface modified SiO2 NPs with silanes and carboxylic acids cannot improve the performance of the HPAM solutions. To conclude, the HPAM/TiO2-PAM, the XG/Fe(OH)3 and XG/TiO2 nanopolymer sols exhibited the best performance in displacing viscous oil in the linear sand-pack tests. The original contributions to knowledge from this research are 1) development of new polymer nanohybrids which enhanced heavy oil recovery, 2) formulation of new synthesis routes for polymer nanohybrids which improved the dispersivity of the NPs into the polymer solutions and the resistance of the polymer solutions to salinity and temperature, and 3) better understanding of the mechanisms contributing to the success of nanohybrids in chemical flooding.
