abstract: Ni-Ceria (Ni-CeO2) nanoparticles (NPs) are promising nanocatalysts for water splitting and water gas shift reactions due to the ability of ceria to temporarily donate oxygen to the catalytic reaction and accept oxygen after the reaction is completed. Therefore, elucidating how different properties of the nanoparticles, such as structure, size, composition, and electronic structure, relate to the activity and selectivity of the catalytic reaction is crucial for developing novel catalysts. In this thesis, we focus on the computational investigation of Ni-Ceria NPs to shed light on their structure/property relationships. From the fundamental point of view, the computational investigation of Ni-CeO2 systems presents a high degree of complexity because they are characterized by strong electron correlation, and it is known that first-principles calculations, such as Density Functional Theory (DFT), may fail to treat the correlation properly. To fill that gap, and with the motivation of increasing the functionality of the deMon2k software, we implemented the Hubbard model, commonly known as +U, in the framework of Auxiliary Density Functional Theory (ADFT) to treat the correlation explicitly. The formulation and implementation of our “ADFT+U” model are discussed in Chapter 3. On the other hand, in Chapter 4, we introduce new auxiliary functions for pseudo-potentials addressing the shortcomings of the auxiliary functions in previous versions of deMon2k, and validate ADFT for Ni-Ceria systems. It is known that the global optimization of nanoparticles characterized by complex potential energy surfaces with many local minima, such as Ni-Ceria NPs, remains challenging and time-consuming. In Chapter 5, we use machine learning (ML) regression and its uncertainty -- an active-learning (AL) strategy -- for the global optimization of the nanoparticles using DFT calculations. The method allows the learned structure-energy relationships to improve iteratively when more data are obtained from DFT calculations of promising structures indicated by the AL. Additionally, further investigation of the NPs by mass-scaled parallel-tempering Born-Oppenheimer molecular dynamics (PT-BOMD) resulted in the same global minima (GM) structures found by AL, demonstrating the robustness of our AL search. This AL strategy has shown to be a powerful tool for learning from small datasets and assists in the global optimization of complex electronic structure systems, such as Ni-Ceria NPs, allowing us to determine the structures of Ce(y-x)NixO(2y-x), with (x=1, 2, 3; y=4) and Ce10Ni3O26 NPs for the first time. Finally, in Chapter 6, we present a novel AL model to search for the catalytic sites of the NPs based on single-point calculations, which is an essential step to explore the reaction over the nanoparticle surface. In summary, this thesis provides crucial insights into the relationships between the structures, the electronic structures, and the catalytic properties of Ni-Ceria NPs for the water-splitting reaction. For instance, we found that Ni-Ceria NPs with a 3Ni/1Ce ratio exhibit a more favourable adsorption energy, which relates to the electronic properties of the cluster, with a computed HOMO-LUMO gap of about 2 eV, and so, better catalytic properties for the water-splitting reaction.

abstract: It is acknowledged that Full Waveform Inversion (FWI) techniques are sensitive to the set of model parameters that we choose for the minimization procedure. This model parametrization and sensitivity analysis for FWI has been extensively studied for acoustic and isotropic-elastic media. In order to obtain an accurate image of subsurface earth, it is necessary to include both anisotropy and attenuation in inversion procedures as subsurface materials are far from being isotropic or elastic. In this thesis, we formulate the sensitivity analysis for FWI in viscoelastic-isotropic/anisotropic media. To develop such analysis, we construct a framework based on the first order perturbation theory called the Born approximation to find the sensitivity of the FWI to isotropic, anelastic and anisotropic parameters. Sensitivities are, essentially, radiation patterns induced by scattering of the seismic waves from inclusions in medium properties in an isotropic background. Most importantly, we investigate the effect of the inhomogeneity angle which is unique to viscoelastic waves, on these radiation patterns (scattering potentials) and also on amplitude-variation-with-offset or azimuth (AVO/AVAz) analysis. By decomposition of the scattering potentials into isotropic, viscoelastic and anisotropic components, we specify the effects of anelasticity, inhomogeneity of wave and anisotropy on radiation patterns and the linearized AVO/AVAz equations. Moreover, we show how the obtained scattering potentials reduce to the linearized AVO/AVAz equations without using the solution of Zoeppritz equations.  This analysis is the starting point for any FWI strategy in a complex media exhibiting both attenuation and anisotropy, as the scattering potentials that we obtained can be effectively implemented to choose a suitable model parametrization.

subject: Architecture Education--Religious

abstract: Our current century is fraught with disconnection. Extreme accessibility and connectivity facilitated by social media platforms and instant communication has given birth to a paradox: we are more connected than ever before, and increasingly distant - not only from one another, but also, and more detrimentally, from ourselves. Our sense of belonging often rests in our public networks, with our ability to self-actualize built upon external determinants and fluctuating opinions. The result is a void within each of us that hungers for deeper meaning, more powerful connections, and extraordinary experiences. I believe that architecture is uniquely and favorably positioned to meet these needs. This thesis seeks to address some key questions in the field of research surrounding sacred space/ spiritual architecture. Presently these include the following: what is the historical place of sacred/ spiritual architecture in society and how is it defined/ exemplified? What common elements are present in transcendental experiences of space? What elements of space move us emotionally, physically, psychologically and spiritually? And finally, can we consciously create the sacred and the intangible with tangible materials, or does spiritual experience lie in the intersection of seeming opposite: what is seen, and what is felt. This thesis argues that the buildings we create must supersede their mathematical and structural components. Our environments cannot be composed of brick and mortar only, but must extend themselves to encompass the realms of emotion and experience. This results in structures that impart feelings of delight, and offer experiences which return us to moments of childlike wonder.

abstract:
Obesity is a significant public health problem in Canada. Increasingly, factors that are beyond the individual are being identified as important drivers of the current obesity epidemic. Drivers like prices, taxes, and government policy are jointly identified as population-level determinants of obesity that have resulted in its rapid growth. While these population-level determinants have been identified as important, their impact has not been explicitly quantified in Canada. The geographic distribution of obesity prevalence in Canada is one issue that could potentially highlight the important role that population-level determinants of obesity play.
This dissertation’s objective is to assess the importance of population-level determinants of obesity in Canada by quantifying their impact on individuals living in different regions of the country. Canada has, roughly, an east to west gradient of obesity, with the Atlantic provinces exhibiting the highest prevalence of obesity. I characterize the difference between the Atlantic provinces and other regions of Canada (Quebec, Ontario, the Prairies, and British Columbia) in two ways: the difference in average body mass index (BMI) and the difference in BMI distributions. To estimate the contribution of the population-level determinants to these differences I apply Blinder-Oaxaca decompositions and quantile regression to national level data from the Canadian Community Health Survey. I show that the population-level determinants are important in describing cross-regional differences in obesity in Canada and their importance becomes larger at high percentiles of the BMI distribution, especially in females. I explain how this is consistent with the ecological model of obesity’s portrayal of the population-level determinants of obesity.
Parallel to meeting the overall objective of this dissertation, I assess the added value of corrected BMI values in obesity research. Correction equations are generally used to adjust self-

reported BMI values so they resemble measured BMI values on aggregate. I assess their usefulness by establishing a new correction equation and comparing that correction to established Canadian correction equations, measured BMI, and self-reported BMI. I determine that corrected BMI is not always superior to self-reported BMI and discuss the settings where corrected BMI is useful.

abstract: A verification and validation analysis of two widely-used open-source compressible-flow solvers, rhoCentralFoam and SU2, is performed for several flow problems relevant to the supersonic aerodynamics of small-scale, autonomous aircraft concepts. Vehicle concepts used as research platforms to test new aerospace technologies, such as advanced propulsion systems or large sensor payloads, require major modifications to conventional, large-scale, manned, supersonic airframe design. High-fidelity numerical simulation of these concepts in academic settings often requires the use of in-house or available open-source tools instead of expensive commercial software or those with export-control restrictions. The one-dimensional shock tube problem, two-dimensional supersonic turbulent boundary layer, and three-dimensional delta wing are simulated with both solvers. The effects of flux scheme, flux limiters, and Courant-Friedrichs-Lewy (CFL) number on solution accuracy, stability, and solver speed are assessed. The solvers' limitations and their usefulness as supersonic aircraft design tools in a holistic sense are discussed.

subject: General GNSS high-sensitivity receiver

abstract:
GNSS have established themselves as the dominant positioning technology to provide location and navigation solutions with high reliability and accuracy with low-cost portable user devices. However, receiver performance can be significantly affected by operational environments. High attenuation and severe multipath fading degrade the signal tracking performance and limit the use of GNSS in indoor and urban environments. Therefore, this thesis focuses on enhancements of a context-aware high sensitivity software GNSS receiver.
To improve the GNSS signal tracking sensitivity, three levels of effort have been made. Firstly, four signal integrators, namely bit aiding coherent integrator, bit extracting coherent integrator, magnitude non-coherent integrator and squaring non-coherent integrator are developed and tested in the high sensitivity GNSS software receiver GSNRx-hsTM to increase the processing gain. While bit aiding coherent integrator utilizes time-tagged external data bit aiding, others do not require external data bit aiding. Secondly, three multi-correlator based frequency estimators, namely the FFT-based maximum-likelihood frequency estimator, the fast-slow frequency discriminator and the power-based frequency discriminator, are developed to improve the weak carrier tracking. Simulations show that these frequency estimators can provide about 4 to 5 dB gain compared to the traditional phase-different discriminators. The third effort is the development of the centralized vector-based tracking loops, the decentralized vector-based tracking loop, and the navigation-domain tracking loop. Using a GPS only constellation, it is shown that vector tracking can provide 2 to 6 dB improvements over scalar tracking. From tests with hardware simulated data, even without data bit aiding, the developed centralized and decentralized vector-based tracking loops with the multi-correlator frequency discriminator and the navigation-domain tracking loops can track signals as low as 8 dB-Hz. Field test conducted in a typical North American house shown that the centralized vector-based tracking loop and the scalar-based tracking loop can successfully track signals in a basement and provide metre-level position.
As the high sensitivity tracking techniques developed herein are different from conventional tracking methods, metrics that can be used to indicate the environment change and allow the receiver to have context-awareness are proposed and explored. From experiments conducted in residential homes, it is found that the sole use of C/N0 values to detect the transition between outdoors and indoors is optimistic; in contrast, it is found that the Ricean K-factor, can detect outdoor-to-indoor transitions by capturing the C/N0 variation due to multipath fading and allow the receiver to adjust the processing strategy before the transition happen.

abstract: Due to the variety of NoSQL databases and database models, along with their schemaless nature, it has been a challenge to develop a framework that can enforce fine-grained access control policies and can be applicable to multiple NoSQL databases ranging over a variety of database models. In this thesis we present SUDO: Semi- / Unstructured Data Organization Framework for defining pseudo-dynamic schemata. The SUDO framework is comprised of four main features. i) SUDO is designed to be applicable to multiple NoSQL database technologies and models. ii) SUDO operates between the database and the application layer. iii) SUDO provides the tools for defining a pseudo-dynamic schema for databases with semi-structured or unstructured data. The pseudo-dynamic schema is based on Description Logic ontology. iv) SUDO provides the tools for validating database queries against that pseudo-dynamic schema and weaving queries and access control policies to simultaneously evaluate and authorize the query results.We present the SUDO framework in three parts. First, we present AReBAC, an attribute-supporting ReBAC model for Neo4j, a graph database. AReBAC focuses on weaving queries and policies for efficient authorization. AReBAC is also accompanied by GP-Eval, a query evaluation algorithm that surprisingly performs orders of magnitudes faster than the Cypher query evaluation engine provided by Neo4j, and introduces a new constraint satisfaction programming technique that we dubbed Live-End Backjumping. Next, we present SUDO as a framework for MongoDB, a document-based database. At this stage we focus on defining a pseudo-dynamic schema for a MongoDB state, and validating database queries against the pseudo-dynamic schema. Finally, we further extend SUDO by presenting a set of relations between queries and polices required to weave the two together and form a query that simultaneously evaluates and authorizes the query results. We also present a set of tests to verify if a query and a policy are compatible with each other, and identify the reason for incompatibility (if any). We then generalize SUDO so that it is not only specific to MongoDB, by presenting AReBAC as an extension of SUDO, and applying SUDO to Cassandra, a wide-column database.

abstract: Newer model vehicles are often equipped with or capable of supporting hands-free systems that use voice-recognition technology. Although voice-recognition technology is viewed favourably among the public, it is not clear whether these systems should be considered safe alternatives to traditional handheld phones and visual-manual integrated systems. To answer this question, an exhaustive search was conducted to capture all experimental studies involving secondary tasks with voice-recognition systems where driving performance was measured. Meta-analyses for the performance measures of detection, reaction time, lateral control and longitudinal control were conducted with 43 studies meeting inclusion criteria. Some driving performance benefits were observed relative to visual-manual systems, but there were also considerable impairments relative to baseline driving. The results of the study indicate that voice-recognition systems, despite minimizing eyes-off-road time, have a distraction cost. Implications for driver education, voice-recognition system design and future research are also discussed.

abstract: Steam-based thermal recovery process is the most commonly used recovery process for bitumen production from oil sands reservoirs.  The most used thermal methods are Steam Flooding (SF), Cyclic Steam Stimulation (CSS), and Steam Assisted Gravity Drainage (SAGD). The choice of method depends on the geology, initial reservoir conditions, and the viscosity of the oil.  In the research documented here, a detailed examination of the Liaohe heavy oil operation is analyzed from field data. The analysis relies on from a construction of detailed geological and reservoir models and a history match of the CSS and steam-injection gravity drainage operation.  The model is then used to evaluate steam flooding and automated control of the recovery process.  Also, a submodel from the history-matched reservoir model is used to understand, at fine scale, the dynamics of CSS.  The results show that conducting steam flooding post CSS provides an effective means to achieve greater recovery factors at reasonable steam-to-oil ratios.  Also, automated control by using proportional-integral-derivative control can yield further improvements of the process performance.  The results of the detailed ultra-refined CSS models demonstrate that CSS dynamics are complex due to steam-based dilation and steam condensation.  The overall results of the research reveal that CSS is an effective thermal recovery method that can be used with post-CSS processes to produce the majority of oil from the reservoir.

abstract: Vitamin D deficiency (<50nmol/L 25-hydroxy vitamin D)  affects more than 1 billion people worldwide. Furthermore, cardiovascular disease (CVD) is a common cause of mortality globally. Observational studies have shown that vitamin D deficiency and CVD are associated, specifically in the chronic kidney disease (CKD) population whom are burdened with both increased risk of CVD-related death and vitamin D deficiency, though whether this relationship is causal in nature is not clear. Electrocardiogram recordings are used to quantify sympathetic and parasympathetic (vagal) control over the heart (cardiac autonomic tone, CAT), which has been shown to predict CVD-related outcomes.  A series of studies was conducted across a range of populations with varying kidney function to assess the impact of vitamin D deficiency and supplementation on CAT. In healthy humans undergoing an angiotensin II (AngII) vascular stress test prior to vitamin D supplementation, subjects with low 1,25(OH)2 vitamin D experienced withdrawal of cardioprotective vagal tone and an upwards shift in overall cardiosympathovagal activity [(∆HF from baseline = -6.98±3, p=0.05; ∆LF:HF from baseline = 0.34±0.1, p=0.043 vs. above 25th percentile]. Following 4 weeks of oral vitamin D3 supplementation, vagal activity during the same AngII stressor was restored (∆HF from baseline 9.5±5 vs. -2.8±3, p=0.07 vs. pre-supplementation).  The same study with vitamin D deficient IgA nephropathy (IgAN) subjects yielded similar results. The VITAH Trial then aimed to assess whether a causal relationship existed between activated vitamin D supplementation and CAT in end-stage kidney disease (ESKD) patients requiring hemodialysis. In contrast to healthy and IgAN subjects, six weeks of oral 1,25(OH)2 D supplementation (0.25mcg alfacalcidol 3x per week) or combined activated and nutritional supplementation (additional 50,000IU ergocalciferol 1x per week) enhanced cardiosympathovagal balance during hemodialysis in vitamin D deficient subjects (activated: n=13, ∆LF:HF: 0.20 ± 0.06, p<0.001 vs. ∆LF:HF in non-deficient; combined: n=8, deficient: ∆LF:HF: 0.15 ± 0.06, p<0.001 vs. ∆LF:HF in non-deficient). These novel findings indicate that vitamin D deficiency impairs the regulatory capabilities of the autonomic nervous system during vascular stress, and that vitamin D supplementation may mitigate the risk of CVD-related mortality in humans specifically in the setting of advanced CKD.

abstract: Borrelia burgdorferi and other spirochetes that cause Lyme disease effectively evade the acquired immune response through antigenic variation. The VlsE antigen is expressed on the spirochete surface during mammalian infection. Virtually unlimited numbers of variants are generated through segmental gene conversion events at the vlsE gene from a series of nearby silent cassette sequences that are homologous to the variable region of vlsE. In contrast to other antigenic variation systems, the molecular mechanism for this switching is unknown. Switching at vlsE is dependent on mammalian host factors and the only known requirement is the RuvAB branch migrase; RecA and many of the other homologous recombination proteins in B. burgdorferi are not required. In this study, we developed a new assay for switching at vlsE based on PacBio sequencing and an analytical pipeline that allows the analysis of tens of thousands of full-length variants. We developed the first fully-automated and unbiased method to accurately identify switch events and non-templated mutations from sequence data. This software also contains a large suite of dataset management and analysis tools to quantify many aspects of switch events and the switching process in the dataset. Following a time-course of B. burgdorferi infection in immunocompetent and immunocompromised mice in a variety of tissues, we uncover a series of new insights into recombinational switching at vlsE. We demonstrate that although switching requires mammalian host factors, the rate of vlsE switching is unaffected by the presence or absence of the required immune system. We identify residues that undergo diversifying and stabilizing selection in the VlsE protein in the presence of acquired immunity. We also report accurate rates of recombination and nontemplated mutation, the size and origin of switch events, a role for local sequence homology in promoting switching, and that switch events accumulate in a clustered rather than uniform fashion. We also quantify a secondary mechanism of sequence variation by demonstrating that polymerase slippage generates in-frame, surface-localized insertions and deletions that contribute to VlsE variability.

abstract: Avian Reovirus (ARV), Chicken Astrovirus (CAstV), and Hemorrhagic Enteritis Virus (HEV) are important enteric pathogens affecting poultry production around the world. These agents are the causative agents of Viral Arthritis (VA), White Chick Syndrome (WCS), and Hemorrhagic Enteritis (HE), respectively. In meat-type chickens, pathogenic strains of ARV can replicate in the joints leading to edema, inflammatory cell infiltrate, and fibrosis, which results in rupture of tendons. Similarly, pathogenic strains of CAstV can cause transient increase in mid to late embryo mortality, reducing hatchability between 4-68%, with some hatched birds exhibiting pale plumage; these “white chicks” (WCS) usually die within the first week of life. In turkeys, HEV infection has two presentations: 1) A clinical disease consisting on gastrointestinal hemorrhages, depression and immunosuppression (Clinical HE); and 2) subclinical infection, consisting in immunosuppression and causing economical losses due to secondary infections and plant condemnations. In recent years, these diseases have gained importance in western Canada as a result of the economic losses sustained from these infections in: a) feed conversion, b) high number of culls/first week mortality, c) secondary bacterial infections, c) processing plant condemnations; and d) costly disruptions to the Canadian Supply Management system. This thesis focuses on molecular characterization of ARV, CAstV, and HEV obtained either from clinical samples (ARV, CAstV), or from cases suspected to have subclinical infection (HEV) in poultry farms located in western Canada. The biological samples from chickens (ARV, CAStV) and turkeys (HEV) were collected from cases submitted for post-mortem examination and diagnosis to Poultry Health Services (PHS), a private poultry consulting firm, located in Airdrie, Alberta, western Canada. Further studies are required to assess the virulence of these isolates for understanding their impact in the western Canada Poultry Industry and for the implementation or enhancement of vaccination practices.

abstract: Abnormalities in sperm function at the submicroscopic level (not detectable during routine semen evaluation) influence bull fertility and therefore the efficiency of cattle production. New knowledge regarding the molecular basis of spermatogenesis and sperm function will enable us to develop evidence-based approaches for improving fertility. The overall aim of this thesis was to investigate role of Na/K-ATPase (the sodium pump) isoforms in sperm function, Sertoli cell function and male fertility. In fresh bovine sperm, I identified two distinct pools (raft and non-raft) of the testis-specific isoform of Na/K-ATPase (ATP1A4) in the plasma membrane. The raft pool of ATP1A4 interacted with caveolin-1 and EGFR, whereas the non-raft pool of ATP1A4 interacted with EGFR, Src and ERK1/2 in capacitated sperm. In addition, a comprehensive analysis revealed that the ATP1A4 interactome differed between raft and non-raft fractions of capacitated sperm. Specifically, ATP1A4 interacted and co-localised with plakoglobin (member of β-catenin family of proteins involved in cell adhesion) in the equatorial segment of capacitated sperm; this suggests a potential role for these proteins in sperm-oolemma fusion. During investigation of ATP1A4 involvement in lipid rafts, I determined that ATP1A4 content and activity were increased during capacitation, perhaps due to translation of ATP1A4 mRNA in mitochondrial or mitochondrial-type ribosomes. In frozen-thawed sperm, content and activity of ATP1A4 was greater in high- versus low-fertility bulls and significantly correlated with fertility. Additionally, ATP1A4-induced ROS, calcium, actin polymerization and tyrosine phosphorylation were also involved in regulating post-thaw sperm function in these bulls. My results also demonstrated that prepubertal rat Sertoli cells expressed ATP1A1 (the ubiquitous isoform of Na/K-ATPase) and that ATP1A1-ouabain interaction regulated formation (modulation of claudin 11 and connexin 43 expression) and function (transepithelial electric resistance) of Sertoli cell junctional complexes through Src-EGFR-ERK1/2- CREB pathway in a dose-dependent manner. Overall, results demonstrated that isoforms of Na/K-ATPase have unique roles in controlling several aspects of sperm and Sertoli cell physiology, acting through its well-established enzyme activity and signaling functions. Consequently, isoforms of Na/K-ATPase are potential candidates for reversible male contraception and a biomarker for male fertility.

abstract: Digital information has become immensely abundant and ubiquitous in our lives. During work or leisure, we traverse search results, news items, and status updates for a wide range of purposes. Typically, information is displayed as lists ordered by relevance or recency, which may be sufficient for displaying a few items. However, considering the substantial increases in complexity and scale of many information spaces, lists are of limited use for discerning how resources are related or what a collection contains. In contrast, information visualization can utilize our perception to reveal patterns and provide overviews of large datasets.  This dissertation investigates the potential of visualization for navigating growing information spaces, and presents methods for arranging and accessing digital information. Unlike most information seeking models that emphasize informational deficiencies, the approach taken here highlights information practices characterized by curiosity. Picturing the searcher as an information flaneur with an exploratory attitude, we can envision innovative interfaces for accessing information.  Three design studies are presented that are aimed to support casual exploration while attending to the challenges and opportunities of informational abundance. Addressing the diversity of relationships in many datasets, EdgeMaps combines spatialization with graph-drawing techniques. Using an integrated representation it is possible to see the semantic or temporal extent of influence, for example, among philosophers or musicians. Visual Backchannel is motivated by highly dynamic communication channels during large events and integrates evolving visualizations for topics, participants, and photos of ongoing conversations. Approaching the difference in scale between large result sets and individual items, Fluid Views narrows the gap between overview and detail in a zoomable search environment, in which results portray similarity via position and relevance via size and level of detail.  The research is validated by prototype implementations, a large-scale Web study study, deployment during conferences, and consultations with search experts. The dissertation ends with a critical reflection about the role of values in information visualization. The insights gained from empirical and theoretical methods suggest novel forms of information seeking and raise challenges for research and design.

abstract: More than ever, engineering students must be prepared for social responsibility. The 20th-century saw unprecedented social and technical advancement, leading to population growth and depleting natural resources. As a result, engineering educators have been called upon to prepare students for these professional social responsibilities. However, social responsibility is more discretionary and interpretive than legal and ethical responsibilities, and educators lack clarity on what exactly social responsibility entails and how to design effective learning experiences for it. This thesis explores the relationship between student participation in various engineering learning experiences and social responsibility. Results of this study show that fourth- year students were likely to have higher social responsibility measures than first-year students, especially in a professional capacity. Participation in certain learning experiences corresponded to increased social responsibility measures, while others did not. Lastly, the results show that social responsibility measures could be correlated with three professional graduate attributes.

abstract:
In-situ combustion is an effective thermal recovery method and provides an important alternative to steam injection, but it is yet to be widely applied. A factor that has limited the application of ISC (in-situ combustion) is a lack of predictability at both the laboratory and field scales. The ISC process is very complex, and its modeling work requires an understanding of the behaviour of different physical phenomena including phase change, heat and mass transfer, and chemical reactions. A proper experimental kinetic analysis such as ramped temperature oxidation (RTO) provides critical parameters for modeling. In this study, the focus is to model appropriate kinetics and improve reaction models for this process.
Different chemical reactions occur during ISC in different temperature ranges (Nader et al., 2007). For heavy oils and oil sands low temperature oxidation (LTO) dominates below 260°C, yielding partially oxygenated compounds and increasing the viscosity of oil, and as a result, limits the success of ISC. Negative temperature gradient (NTG) is observed from 280°C to 380°C, which is also named the middle temperature oxidation (MTO) or fuel deposition. This temperature range includes thermal decomposition and pyrolysis/cracking of hydrocarbons. Above 400°C, combustion reaction dominates, known as high temperature oxidation (HTO), producing carbon oxides and water.
The objective of this study is to develop reaction kinetic models that can be used to describe the reactions of hydrocarbon fractions at various temperature conditions during the ISC of Athabasca bitumen. In this work, a set of improved kinetic models including LTO, MTO, and HTO reactions based on Saturates, Aromatics, Resins, and Asphaltenes (SARA) fractions in the crude oil are established. These kinetic models are used to reproduce the RTO experimental results through numerical simulation and to obtain successful history matched results. These models are developed using more data sets than what is currently available in the literature.
An important feature of the improved models that differentiates the results of this study from those of previous studies is their ability to handle the whole combustion process starting from LTO to MTO to HTO for the Athabasca bitumen. This research will significantly increase the understanding of different chemical reactions occurring in heavy oil during the entire ISC process, and contribute to the development of reliable numerical models that can accurately predict ISC performance in different temperature scenarios.

abstract: Evidence of the long-toed salamander, Ambystoma macrodactylum, was obtained at nine of thirteen study sites within Waterton Lakes National Park, located in the southwest corner of Alberta. Distribution was scattered throughout the park at elevations ranging from 1280 to 1930 metres. Breeding activity of salamanders in the park occurs from early April to late June, depending on location. Development of salamander larvae in lakes or ponds is usually completed in one season (ie. during one summer); however, the occurrence of two-season development was indicated at Summit Lake (elev. 1930 m). Surrounding terrestrial habitat varied from aspen parkland to subalpine coniferous forest. Using the Schumacher-Eschmeyer estimator, the size of the Linnet Lake adult salamander population based on 1994 field work was estimated at between 3,274 and 4,690 adults (95% confidence interval). During the breeding period in April and May, greater numbers of salamanders migrated on nights when there was surf ace moisture or rainfall, particularly after short dry periods. An unusual 3: 1 (464 females: 155 males) sex ratio was obtained. Females spent an average of 19 days near and at Linnet Lake during breeding activity; males spent an average of 27 days. Several management issues were identified. Included are roadway mortality of salamanders at Linnet Lake, the need for a water quality monitoring program, and potential contamination of breeding sites due to roadsalt and acidification. Measurements indicated that pH values of the aquatic habitat have decreased substantially within the past twenty-five years. The global problem of acid precipitation may be a contributing factor.

abstract: The ecotourism project at Boabeng-Fiema Monkey Sanctuary (BFMS) is a Community-based Ecotourism (CBE) project that has become a popular and fast-growing environmentally friendly segment of the tourism industry in Central Ghana, Africa. The Boabeng-Fiema Monkey Sanctuary’s Community-based Ecotourism project is managed and controlled mainly by the community members in the communities of Boabeng and Fiema. This study examines the relationship between the visitor experience and sustainable ecotourism practices at BFMS. This research expands on the literature concerning the ecotourism project at the site and its sustainability by assessing its 1) socio-cultural sustainability, in terms of improvement of social wellbeing of local people and conserving the local culture; 2) economic sustainability, in terms of income generation and creation of employment opportunities; and 3) environmental sustainability, in terms of protecting the monkey species, the white-thighed colobus and the Campbell’s mona monkey, and the forest. Using participatory observation, interviews, and focus group discussions, the relationship between the visitors experience and sustainable ecotourism practices at BFMS is examined based of on four key features: 1) visitor motivations, 2) visitor activities, 3) visitor satisfaction, and 4) visitor experiences that contribute to economic, socio-cultural, and environmental sustainability. Results of this study show that a better understanding of the visitors’ experience in terms of their motivations, activities and satisfactions can lead to improvements with regards to: a) economic sustainability; b) social-cultural sustainability; and c) environmental sustainability. This research emphasizes the need to improve the visitors’ experience in terms of their connection with the cultural, social, and environmental aspects of community-based ecotourism for the ecotourism practice at BFMS to be sustainable in the long-term.

abstract: This thesis reevaluates Operation Market Garden, the failed Allied airborne invasion of German-occupied Holland in September 1944 by comparing the combat doctrines and practices of the British and German forces that engaged in the campaign, particularly with regards to command and control and the employment of firepower, and seeks to assess the degree to which each force was actually suited to the circumstances that they faced during the operation. The study concludes that German combat doctrine and training, based around a highly decentralized and proactive command ethos and a high level of small-unit tactical proficiency, was a major factor in their ability to effectively cope with the unexpected Allied attack and the confused combat situation it created. Conversely, the British forces were hampered by the fact that their own doctrine, based around rigid centralized control, cautious set-piece battle planning and the maximal use of artillery and aerial firepower, proved itself ineffective in adapting to the confused and fast moving situation that their own surprise offensive created, ensuring that they were unable to achieve their objectives.

subject: Engineering--Petroleum EOR

abstract:
It is widely accepted that thermal methods have become the most effective techniques for Alberta heavy oil reservoirs. However, thermal techniques cannot be applied to many reservoirs, such as deep reservoir or reservoir with thin pay because heat losses will be too severe. Water flooding is an alternative but it can only achieve a very low oil recovery due to severe viscous fingering. Hence, research into other non-thermal recovery methods is necessary.

This thesis presents a laboratory-scale investigation of heavy oil recovery by polymer flooding, ASP (alkali-Surfactant-Polymer) flooding and ASP-foam flooding. The production mechanisms involved in heavy oil chemical flooding and foam-flooding were studied. Several sandpacks saturated with the heavy oil were first waterflooded. Then either polymer, ASP or ASP-foam flooding was conducted. The recovery performance of these displacements was evaluated and compared. The effect of injection rates was also studied. ASP flooding at low injection rate achieved the highest oil recovery. Under the high injection rate, polymer flooding, ASP flooding and, ASP-foam flooding recovered similar amounts of oil. Oil recoveries of polymer-flooding were insensitive to injection rate. Besides, ASP foam flooding of a water saturated core (oil-free) was also conducted. A comparison between the displacements of the oil-free core with that of the previous displacement tests suggested that foam stability was destroyed in the presence of heavy oil.

abstract: Personal navigation is one of the fastest developing fields due to ever changing needs of consumers. Most recently, GPS-based systems have gained popularity in commercial navigation systems. However, a problem arises when the GPS is unable to provide positions due to interruptions in the signals. One way to solve this problem is by using inertial sensors that do not require any outside signals. The thesis deals with the issues related to the design specifications for a completely portable navigation system (PNS). A PNS is defined as a navigation module that is completely transferable from vehicle to vehicle and from one mode of transit to the other and should be able to provide navigation information even for short GPS signal outages. The PNS requires calibration and alignment before navigation can be started. These two topics require different implementation methods to accommodate for the special needs associated with portability. A new method was proposed that can perform calibration of the sensors without any requirement on the PNS shape. Alignment is not required if six sensors are part of the system, however, partial sensor system will require some alignment criteria. For low-cost commercial system, signal sampling requirement is also important as the choice of micro processor, memory card and DAQ card are all cost defining factors. A frequency of 50Hz and timing errors of up to 1 ms did not degrade the navigation results, however, 10 bits resolution produced significant degradation. It was also determined that a heading gyro and a dual axis accelerometer in the horizontal plane with velocity aiding produced comparable results to six sensors unit without any aiding, and hence can be used for low-cost navigation. As a PNS can be used either by a person on-foot or in-vehicle, one of the important issues is to identify the correct mode of transit to apply the most appropriate navigation equations. Consequently, an algorithm was developed and tested to detect mode of transit when the system was attached on the belt of the user. A levelled ground walking scenario produced the best results and the average accuracies of other cases stayed over 90%.

subject: Engineering--Petroleum Recovery Bitumen Solvent Oil Optimization Cyclic

abstract:
Vapour extraction (VAPEX) process has a low production rate and is not suitable for thin reservoirs due to lack of efficient gravity drainage. Cyclic solvent process (CSP) has been proposed to improve the production rate of solvent processes. A major problem of CSP is that during production, the reservoir pressure has to be greatly reduced in order for the solvent gas drive to occur during which oil regains its high viscosity because a significant amount of solvent gas evolves out of oil. Also, at low-to-intermediate pressures, the methane solubility in the oil is not high. Additionally, continuous free gas saturation during early production results in high gas mobility and the pressure, and thus, the drive energy can be quickly depleted by gas production. To overcome the problems of VAPEX and CSP, a new process for in-situ heavy-oil recovery- Enhanced CSP (ECSP) is developed in this study. ECSP effectively utilizes the viscosity reduction and solvent gas drive mechanisms during the production.
ECSP experiments are performed to analyze the mechanisms and develop the optimal combination of two solvent slugs and injection/production strategy to optimize the injection process for improving the CSP in thin heavy-oil reservoirs. It is also shown that other ways of improving CSP is either to repressurize the system using water injection, i.e., conducting cyclic gas-alternating-water injection, or to conduct surfactant-enhanced CSP. Various aspects of ECSP are investigated under different injection sequences of two gas slugs. The impact of foamy solution gas drive mechanism on ECSP is also investigated. Then, phase behavior simulation is carried out for different heavy oil-solvent systems to predict the phase behavior of gas/gas mixtures with heavy-oil. Using a validated simulation model, the impacts of various parameters on ECSP are examined to analyze the mechanisms and illustrate the possible optimum ECSP designs.
This study has produced experimental results for CSP, ECSP, cyclic gas-alternating-water injection, surfactant-enhanced CSP, extended waterflood, PVT data and phase behavior simulation, detailed cyclic solvent injection technique, PVT and simulation models for evaluation and optimization of ECSP, history-match and parametric study of ECSP, and guideline of ECSP for thin heavy-oil reservoirs.

abstract: Soap holes manifest as localized areas of water-saturated, weak sediments which render farmland uncroppable and hazardous. The formation mechanisms and global distribution are largely unknown, despite being inferred as groundwater discharge phenomena on the Alberta prairies over 50 years ago. Here, the first conceptual model for soap hole development and persistence is created using time-series hydraulic and temperature data, electrical resistivity tomography, sediment analyses, and geochemical data (sediment and groundwater) from two locations in Alberta, Canada. The soap holes developed in smectite-rich, dominantly colloidal-size glacial sediments under strong flowing artesian conditions, resulting in quick conditions and liquefaction. Geoelectric and hydraulic conductivity contrasts (2-5 orders of magnitude), as well as groundwater geochemistry, suggest preferential groundwater flow of artesian aquifer provenance through a low permeability confining layer. In addition to natural occurrences, a proportion of soap holes may be the consequence of explosive-source seismic conducted for oil and gas exploration in Alberta.

abstract: The purpose of this study is to describe how the Intensive Care (I.C.U.) social worker responds to the delineated needs of the long-term, chronically, critically ill (C.C.I.) adult patient and their families in I.C.U., and to define and describe appropriate social work roles, functions and protocols required by that specific patient population. This thesis demonstrates that generic social work roles, functions and values are congruent with I.C.U. philosophy and combined with their own and other existing multi-disciplinary protocols can enhance the holistic care of the C.C.I. patient and family. This thesis emphasizes I.C.U. social work as a program priority. The study also describes the acute patient in I.C.U. (before 15 days) and the related crisis interventive work, thus documenting the need for social work interventions at the earliest point in the patients hospitalization. This thesis draws a portrait of the psychosocial, environmental, spiritual and physiological needs of the C.C.I. patient and family. C.C.I. patients have not been addressed in social work literature although it is documented that they make up a proportion of the social work interventions in intensive care. Forty-five percent (approximately) of all public general hospitals in Canada report social work involvement in I.C.U. A unified needs based treatment approach has been put forth with existing social work treatment and protocols in I.C.U. for this specific group. Increased utilization, cost and specialization in I.C.U. plus shifting population groups, illness/ disease patterns have brought a parallel extension of the social work role. Preventative treatment approaches must now concentrate on I.C.U. Syndrome/psychosis patient isolation, communication aids and team strategies to coordinate interventions. The acute care and lifesaving crises that daily occur require psycho-emotional support. This is compounded for the C.C.I. patient by the high incidence of utilization of breathing support equipment which limits communicative interaction between patient and staff. This has definite ramifications on the kinds of psychosocial interventions and therapies normally addressed by social workers. Social work training to date does not include a review of I.C.U. equipment and facilities which necessitates on-the-job orientation to technical terminology. This vital information enables the worker to knowledgeably assist the patient and family and access appropriate professionals in practice. Today, a new, aggressive treatment approach to the long-term C.C.I. patient has been established. This Critical Care Model with its final, common, systems-failure pathway demonstrates that the illlllediate psychosocial, physical and instrumental issues for the C.C.I. patient will arise from the complications, crises and dilemmas of their long term hospitalization rather than their initial illness typology. Synthesis of this information has resulted in sixteen social work protocols pertaining to systems from pre-admission to discharge planning and self-care. This thesis, through its utilization of relevant crossdisciplinary literature and practice data, recommends the inclusion of interdisciplinary education in social work training for intensive care or a combined field/practicum setting, plus initiation of research.

abstract: The Cretaceous Grand Rapids Formation in east-central Alberta is comprised ofprograding deltaic to marginal marine deposits incised by fluvial to marine-influenced fluvial bodies at several stratigraphic levels. Facies mapping and a high-resolution allostratigraphic framework are used to map the 3D distribution of marginal marine units and fluvial bodies. A confined fluvial meander belt in the Colony Allomember is studied in detail using a high-resolution data set of densely spaced wells and seismic time slices. Sediment distribution within the meander belt is particularly fine-grained (i.e., siltstone-dominated), despite indications that discharge was substantial due to the large scale of channels and point bars imaged in seismic data. The fine-grained character of the meander belt is likely a result of: (1) a propensity for muddy counter point bar preservation at the expense of sandy point bar deposits; and (2) limited supply of sand to the depositional system.

abstract:
A simplified multi-step optimization approach for the correction of violating transmission voltages is developed and analyzed in this thesis. The contribution of this thesis are two fold.

A receding horizon multi-step optimization (RHMSO) controller which utilizes a linearized system model is developed. This linear system model is derived from the non-linear steady state power flow equations based on sensitivity analysis. A comparison is made with single step optimization based on Model Predictive Control  (MPC) to test the performance of the proposed multi step approach. Results show significant reduction in load shedding with a smoother system response.

In addition, the concept of bias based error correction is introduced in the linear system model mentioned above. A comparison is made between the bias and non-bias based controllers. The results show that the bias based RHMSO with linear system model provides decrease in settling time and significant reduction in load curtailment, thus achieving better system performance.

abstract:
One of the conceptual developments in the field of resilience is the recognition that individuals have the potential to actually benefit and thrive from adversity. Hence, the concept of four levels of resilience has been suggested - succumbing, surviving, recovering, thriving. Numerous
variables have been postulated to account for individual differences in level of resilience; one that has not received attention is self-talk. Resilient self-talk is introduced as a specific type of positive self-talk utilized during difficult times in our lives ( e.g., "Everything happens for a reason"). University students (N = 291) completed a questionnaire that assessed their (a) self-perceived level of personal resilience (the 4 levels); (b) frequency of engaging in resilient self-talk and its importance to them; ( c) variables related to use of resilient self-talk, including 25
characteristics of resilient individuals ( e.g., optimism, problem-solving ability); reasons for engaging in resilient self-talk (e.g., motivation, focus), experience of life difficulty; and (d) demographic information. The relationship between frequency of self-talk and perceived level
of resilience is considerably stronger than for importance; e.g. frequency (but not importance) of self-talk distinguishes between levels of resilience. A number of variables were also related to the use of resilient self-talk, particularly reframing and social support ( characteristics of
resilience), and motivation (a reason for using resilient self-talk).

abstract:
In order to conduct a successful in situ combustion oil recovery project, sustained propagation of the combustion front within the reservoirs is a must.  Sufficient air must be supplied to maintain the propagating combustion front in the carbon oxide forming mode otherwise unfavorable low temperature oxidation reactions will consume oxygen and not mobilize oil.  When this happens, the combustion process is deemed to be exhausted.
Quantification of the minimum air flux required for sustaining combustion zone propagation is needed to properly match the capacity of the air injection facility to the volume of reservoir which is to be swept by the thermal zone.
One-dimensional combustion tubes are conventionally used to obtain important combustion parameters required for designing an air injection project.  Due to the high heat capacity of laboratory equipment designed for elevated temperature and pressure operation, oxygen addition reactions are promoted by the heat transfer through the core holder walls when the laboratory tests are performed at low air injection rates.  Therefore, when operated at elevated pressures, the combustion tubes are unable to operate at the low air fluxes required to establish the minimum possible air injection flux while maintaining the combustion reactions in an effective mode.
In an attempt to address this issue, a state of the art combustion cell was conceived and utilized as a way of addressing the above mentioned constraints associated with high pressure one-dimensional combustion tubes. The new design enables continuous air flux reductions without having to adjust the air injection rate and as such allows for determination of the minimum flux for specific oils under conditions which are representative of a field scale operation. This research proves that experiments involving core from a typical Athabasca Oil Sands reservoir showed air injection processes, when operated at favorable conditions have the ability to propagate through the heavy oil reservoirs at high temperatures and at injection air fluxes (based on the air injection rate and area at the downstream front location) of under 1 sm3/m2•h.
This thesis presents a new approach to studying in situ combustion processes. It describes the nature of the combustion zone under a variety of conditions and air fluxes approaching those experienced in field projects and provides important information on the nature of reactions and the physics of the process which must be considered when attempting to predict combustion front exhaustion using a numerical simulator. It also gives insight into the limitations in laboratory investigations of in situ combustion as well as the expected behavior of field applications of the in situ combustion process.

abstract: This study addresses the effects that policymakers’ mindsets have upon equity in the policy and practice of math education. It looks beyond math education culture to the general culture, examining the way mindset is constructed and sustained through its discursive expressions in written and spoken language and identifying the positioning it entails and its consequences for learners, educators and policymakers. I explore the notion that due to their similar experience as learners, Israeli math education policymakers hold similar beliefs about math ability. Mapping the mindset behind these shared perceptions, I trace its existence within policy (where it gains authority), as well as its positioning of learners in ways that strengthen and support cultural perceptions while hindering equity. My research addresses complex issues at the personal, social, and political levels. Discourse provides the underlying methodological cornerstone for this study. Discourse analysis serves both for excavation and interpretation of dispositions and mindsets embedded in policy, as well as for the negotiation and re-conceptualization of identities, positions, and policy. Looking at policymakers’ commitment and passion for math education and its promotion, alongside the difficulty in addressing learners whose experience of math is very different from their own, there may be a need for special support in the process of policy and curriculum creation. There may be need for a greater variety of voices in the math education committees, voices that are as passionate about math education and the possibility of promoting it among learners of different dispositions, voices that should echo the position and outlook of different learners.

abstract: The overall objective of reservoir modeling is to reduce the uncertainty of production forecasts by including all available data into the model. Most importantly, the model must be able to match the historical production while preserving geological data. In this work, some new techniques are developed to model the impact of geological uncertainty on history matching and optimization problems. Most of traditional history matching and optimization methods are based on some forms of trial and error schemes. These methods are not usually designed to include and/or preserve the geological continuity of the facies. The Probability Perturbation Method (PPM) is a pixel-based data integration method, which employs the power of multiple-point geostatistics (MPS), to match production data while being constrained to other reservoir data including prior geological information. Using the PPM, one can systematically perturb a spatial distribution of reservoir properties while maintaining the pattern and consistency of the geological information. One of the shortcomings of the original PPM is that there is no straightforward approach to intelligently explore the space of uncertainty (the variability between realizations). In this work, a cluster-aided probability perturbation method (CAPPM) is developed, which can efficiently search the space of uncertainty by clustering the generated realizations. This method allows us to navigate through realizations and approximate the uncertainty bounds with fewer iterations and, consequently, less computational cost. In addition, a new segmentation method, which does not require flow simulation, is presented that allows different parts of the reservoir to be perturbed separately. This method improves the robustness, efficiency, and the convergence speed of the PPM. Three examples with synthetic, realistic and real training images are used to illustrate and validate the developed techniques for various types of reservoirs with different levels of geological complexities.Additionally, this work extends the applicability of MPS techniques for modelling some critical heterogeneities (i.e., complex fracture networks) present in unconventional tight and shale reservoirs. This extension allows us to apply the developed cluster-aided workflow for history matching the production data from multiple-fractured horizontal wells in future studies. Therefore, it is attempted to model complex fracture networks around primary hydraulic fractures using multiple-point geostatistical algorithms. Secondary probability maps, which can be derived from microseismic events, are also included in the modelling process to account for the variability in the extent of the induced and existing fracture networks within a stimulated reservoir volume near the primary hydraulic fractures. A sensitivity study is performed to understand the effect of different parameters on the well flow performance given different fracture network models. Optimization of subsurface flow processes can result in more economical projects. However, ignoring the uncertainty of geological realizations in the optimization process can lead to suboptimal outcomes that can be considerably different from the actual optimal solutions. A robust optimization workflow for the SAGD (steam assisted gravity drainage) process is presented that considers the geological uncertainties by optimizing over a subset of representative realizations obtained from three model ranking techniques. The first method is by applying the base case well locations and operating constraints to all the realizations and running simulations. The realizations are then ordered according to their resulting Net Present Values (NPVs). In the second ranking method, the clustering of a low-dimensional cumulative steam-oil ratio is employed as the feature vector for the SAGD process. Finally, the third method relies on kernel-clustering of permeability realizations using multidimensional scaling and similarity metrics. Although the best solution is obtained by the second ranking approach using the simulation results, the third method is more appealing as it provides competitive results using the static data only.

abstract: The demands for accurate positioning and navigation applications in complex indoor environments such as emergency call positioning, fire-fighting services, and rescue operations are increasing continuously. Global Navigation Satellite Systems (GNSS) receivers, while ubiquitous in outdoor positioning, are not effective indoors. One of the best solutions to solve this problem and increase the accuracy of the user's position in indoor areas is to apply other sensors. This research takes advantage of Bluetooth Low Energy (BLE) technology, vision systems, and Artificial Neural Networks (ANNs) to improve the accuracy of the position solutions in indoor environments for pedestrian applications. BLE technology faces challenges related to the Received Signal Strength Indicator (RSSI) fluctuations caused by human body shadowing. This thesis presents methods to compensate for losses in the RSSI values by applying ANN algorithms to RSSI measurements from three BLE advertising channels. The resulting improved RSSI values are then converted into ranges using path loss models and trilateration is applied to obtain indoor positions. Two neural network algorithms were implemented. The first used only the RSSI values while the second incorporated a wearable camera as an additional source of information about the presence or absence of human obstacles. The results showed that the two proposed artificial-based systems could enhance RSSI due to human body shadowing and provide significantly better ranging and positioning solutions than fingerprinting and trilateration techniques with uncorrected RSSI values. Two proposed systems provided 3.7 m and 6.7 m positioning accuracy in 90 % of the time in a complex environment with the presence of the human body, nevertheless, the fingerprinting and the classic algorithms offered 8.7 m and 12.3 m position accuracy in the same situation, respectively.

abstract: Bovine spongiform encephalopathy (BSE) is a transmissible, neurologic disease of cattle that decimated the cattle industry in many countries when it was discovered to be zoonotic. This disease is caused by a unique pathogen believed to be entirely composed of a misfolded, degradation-resistant form of a host-encoded protein. No therapies or cure currently exist for BSE, and so understanding the pathogenesis and host genes involved in this process could guide work to find ways to prevent or treat this invariably fatal disease. To identify genes playing a role in BSE susceptibility in cattle, genetic analysis was carried out on cattle that were experimentally-infected with BSE and showed variable disease outcomes. Chapter 2 explores potential genetic reasons for an abnormal outcome following oral BSE challenge. This analysis found that breed composition contributes to BSE outcomes in these experimental animals as well as in Canadian BSE field case cattle. In Chapter 3, an in-depth single nucleotide polymorphism (SNP) chip was used to genotype more than 200 experimental BSE challenged cattle with variable disease outcomes. Several genes with the potential to impact cellular calcium levels were identified as contributing to BSE susceptibility. The results also indicated that relatedness of the animals and breed composition are playing a role in the disease status. With several genomic targets identified as important, the research in Chapter 4 explored these genomic regions with targeted next generation sequencing. This analysis flagged additional SNPs in or near genes that can potentially alter the expression of genes involved in BSE pathogenesis. Experimental BSE susceptibility appears to be polygenic, with several genes each contributing a small amount, and this seems to be linked to relatedness and breed. The genes identified are highly expressed in the central nervous system and play a role in the function, maintenance, and survival of cells critical to this tissue. Several genes are linked to intracellular calcium homeostasis, a critical process playing a role in prion and other protein misfolding, neurodegenerative diseases. Additional work to decipher the contribution of the host breed and the breed of the BSE inoculum is warranted to understand the observed breed effects.
