abstract: Patients with esophageal and gastric cancer typically present with an advanced tumour formation and severe symptoms such as progressive dysphagia, nausea, and weight loss (J. Lagergren & Lagergren, 2010; Zali, Rezaei-tavirani, & Azodi, 2011). Surgical treatment is the preference for both diagnoses, however often results in functional digestive complications (Bhargava & Chasen, 2010). Given the myriad of symptoms pre and post treatment, it is clear that health related quality of life (HRQL) is affected for these patients. PA has consistently and repeatedly improved HRQL in cancer patients (Ferrer, Huedo-Medina, Johnson, Ryan, & Pescatello, 2011). Only a few studies have identified potential PA effects in gastric and/or esophageal cancers, with inconsistent results (Bhargava & Chasen, 2010; Feeney, Reynolds, & Hussey, 2011; Lee et al., 2010; Na, Kim, Kim, Ha, & Yoon, 2000; Tatematsu, Park, Tanaka, Sakai, & Tsuboyama, 2013; Tatematsu, Ezoe, et al., 2013; Zalina, Lee, & Kandiah, 2012). To further explore the relationship between PA and HRQL in gastric and esophageal cancers, a cross-sectional one-time survey was completed in a GI outpatient clinic in Calgary, AB. Pearson correlations revealed a positive moderate association between total PA minutes and HRQL (r=.40, p=.03). Future research should consider interventions (education or programming) that promote PA participation in this unique population.

abstract: Extensive studies exist on various aspects of travel behaviour of the general population; however, few works explore the commuting behaviour of university commuters. This thesis investigates university commuters' commuting habits/attitudes to better understand their commuting behaviour and compares predictive models' performances on university commuters' transportation mode choices. For this research, an online survey was administered in March 2020 among the University of Calgary members to shed light on the current travel choice preferences of the university commuters, investigate factors affecting their mode choice, examine their satisfaction level toward various modes, and uncover ways to encourage more sustainable transportation. Further, the data is used to develop traditional discrete choice models and novel machine learning algorithms to predict commuters' transportation mode choice and examine the importance of various factors on their mode choice. The aggregated transportation mode share of the survey respondents shows that 57.89% of survey respondents are either public transit or active mode users, indicating a high percentage of sustainable transportation mode users among university commuters. Various characteristics of survey respondents were shown to be important in their travel behaviour, such as socio-demographic, household and geographical location. It is shown that both age and income level positively affect car usage while negatively affect public transit usage. The geographical analysis also indicates that travel distance and accessibility to transit facilities influence university commuters' mode choice decisions. As travel distance increases and accessibility to transit facilities decreases, university commuters prefer to use more cars than public transit and active modes. Further, it is shown that university members have various satisfaction levels of using different transportation modes and consider various barriers to use them. It is shown that university status and socio-demographics affect commuters' attitudes toward satisfaction level and barriers to use sustainable modes. Overall, employees are shown to be highly concerned about the environmental footprint of using cars; although, they are mainly car commuters. In contrast, students are determined to be more concerned about driving costs and parking availability. In terms of transit, travel time commuting and consistency are determined to be common concerns of university commuters. Similar to transit, the weather condition is determined to be the most important concern for using active modes. The results of the descriptive analysis are further used for policy recommendations to different university administrations to encourage more use of sustainable transportation. Besides descriptive analysis, the prediction performance of various machine learning classifiers is compared with the traditional multinomial logit model on predicting the University of Calgary commuters' transportation modes. The comparison results show that the Extreme Gradient Boosting (XGBoost) method performs better in travel mode choice prediction of the university commuters for higher overall accuracy and F1-score. In addition to the performance comparison, this thesis estimates the relative importance of explanatory variables on various models and shows how they relate to mode choices. This research shows that travel-related information is more influential on machine learning algorithms, while socio-demographic and household characteristics have more effect on the utility functions of the multinomial logit model.

abstract:
In survival analysis, a number of regression models can be used to estimate the effects of covariates on the censored survival outcome. When covariates can be naturally grouped, group selection is important in these models. Motivated by the group bridge approach for variable selection in a multiple linear regression model, we consider group selection in a semiparametric accelerated failure time (AFT) model using Stute's weighted least squares and a group bridge penalty. This method is able to simultaneously carry out feature selection at both the group and within-group individual variable levels and enjoys the powerful oracle group selection property. Although the group bridge penalized approach can effectively remove unimportant groups, it cannot effectively remove unimportant variables within the important groups. To overcome this limitation, the adaptive group bridge method is proposed. We show that the adaptive group bridge method obtains the oracle property. Simulation studies indicate that the group bridge and adaptive group bridge approaches for the AFT model can correctly identify important groups and variables even with high censoring rates. A real data analysis is provided to illustrate the application of the proposed methods.

We further study a nonparametric accelerated failure time additive regression (NP-AFT-AR) model whose covariates have nonparametric effects on the survival time. The proposed model is more flexible than the linear model and can be fitted to high-dimensional censored data when some components are unknown non-linear functions. B-splines are used to approximate the nonparametric components. A group bridge penalized variable selection approach based on the inverse probability-of-censoring weighted least squares is developed to select nonparametric components. The proposed approach is able to distinguish the nonzero components from the zero components and estimate the nonzero components simultaneously. Computational algorithms and theoretical properties of the proposed method are established. Simulation studies indicate that the proposed method has satisfactory performance even with relatively high censoring rates. Two real data analyses are used to illustrate the application of the proposed method to survival data analysis.

abstract: Fairness, i.e., lack of bias during a decision-making process is a desirable property in any software system that is used to make critical decisions (e.g., mortgage approval). However, with the rise of Machine Learning (ML) systems, the concern for unfair systems is also growing rapidly as ML systems are inherently difficult to understand and debug. Moreover, datasets that contain various types of biases can be drastic to the users and systems that utilize these datasets. We have already seen evidence of the drastic influence of bias in various cases, ranging from job recruitment to parole approval. As a result, fairness metrics and mitigation approaches are being increasingly necessary to deal with this issue. Given the growing importance of bias detection and mitigation approaches for ML software systems, it is important to learn how bias is detected and mitigated in ML software systems and datasets and how we could assist in the detection and mitigation of such biases using novel toolkits. In this thesis, we explore this topic from two dimensions: (1) First, we qualitatively study how fairness APIs (i.e. software libraries) are used in the wild (i.e., in open-source ML software systems) to detect and mitigate diverse use cases. (2) Second, we develop a suite of toolkits to support the detection and mitigation of labeling inconsistency bias in sentiment analysis datasets for software engineering (SE). A labeling inconsistency arises when two similar sentences in the datasets have different labels, whereas they should ideally have the same labels. Our major observations in this thesis are: (1) Fairness APIs are increasingly being used in diverse real- world use cases, but developers find it challenging to properly use the APIs. (2) Despite having several fairness APIs, we still need new toolkit support besides the fairness APIs to address a bias like labeling inconsistency in sentiment analysis for software engineering (SA4SE) datasets. Our developed toolkits can aid in this task. (3) Our developed toolkits can be adapted to address labeling inconsistency bias problems in any textual datasets that are used to build classification-based ML models.

abstract:
In recent decades, growing concerns about the increasing atmospheric carbon dioxide (CO2) levels have led to a global push towards the mitigation of anthropogenic CO2 emissions from fossil fuels. Clean coal technologies such as the calcium looping cycle show potential for capturing CO2. In this research, the thermodynamic and kinetic simulations of the CO2 capture process on calcium-based sorbent of calcined dolomite were investigated using Aspen Plus software. Furthermore, the performance of dolomite was compared with that of Cadomin limestone in the temperature range of 600-750°C. The experimental data and model results both illustrated a shift in the reaction mechanism with respect to temperature at 650°C.
Novel mixed catalyst-sorbent pellets were prepared with different contents of potassium carbonate and calcium oxide as the catalyst and sorbent, respectively. Experiments were performed on the steam gasification of two different types of coal with these pellets in a fixed-bed reactor. Boundary Dam lignite coal (low-rank coal) demonstrated a higher reactivity than the Genesee subbituminous coal (medium rank). A maximum hydrogen fraction of 80% (dry basis with nitrogen) was obtained from steam gasification of lignite using composite pellets with 50% catalyst at 700°C.
A modified catalytic hydrogen production reaction integrated novel gasification (M-HyPr-RING) process was then developed for high-purity hydrogen production from the steam gasification of ash-free coal. The steam gasification experiments were conducted in the same reactor with different catalyst loadings with and without sorbent. A maximum hydrogen molar fraction of 85% was observed with 20wt% catalyst and a calcium oxide to carbon ratio of 2 at 675°C under nearly atmospheric pressure.
High-purity hydrogen production from the steam-only gasification of woody biomass integrated with CO2 capture was also explored through process simulation in Aspen Plus software, in order to determine the effect of CO2 capture on gasification at a demonstration plant scale. The model was validated with experimental data available in the literature, and a reversible carbonation/calcination reaction of calcium oxide with CO2 was added. The CO2 capture was predicted to enhance hydrogen purity, which in turn improved the higher heating values by 3 times and the cold gas efficiency by 28%.

abstract: In this thesis we examine the properties of the absolute Norlund Summability (ANS) method and its application to Fourier Series of a function f(x), periodic with period 2π and integrable L. In chapter II we discuss the various consistency theorems for ANS. Chapter III consists of a theorem on the ANS of Fourier Series of a function f(x) belonging to the class Lip α. Chapter IV contains a result on the ANS of Fourier Series when ∅(t)= ½{f(x-t)} is of bounded variation in the interval (O, π). In 1959 Varshney [16] proved a theorem on the absolute harmonic summability of a series related to Fourier Series of f(x) when ϕ(t) is of bounded variation in the interval (O,π). In Chapter V we prove a theorem on the ANS of Fourier Series when cp(t) is of bounded variation which generalises the result on absolute harmonic summability due to Varshney and includes the result given in Chapter IV. In Chapter VI we prove a theorem on the ANS of Fourier Series under the condition φ(□(1/t))|ϕ(t)| = 0(1) where φ(n) is a monotonic increasing function.

abstract: Inflammatory bowel disease is characterized by chronic inflammation of the gastrointestinal tract. The pathogenesis is thought to be due to a dysregulated immune response to intestinal microbiota. Approximately 15% of the risk is genetically linked and approximately 85% is attributed to environmental exposures. Dietary factors like retinoic acid (RA), a vitamin A metabolite, have been linked to the onset of IBD by influencing intestinal immune function. RA induces Tregs and inhibits the actions of proinflammatory Th-17 cells. We have previously described decreased CD103+ DCs numbers in the intestinal compartments of RARα-deficient mice (RARαvillin mice). We sought to generate an experimental system to identify signaling pathway(s) or mechanism(s) that might be governing these effects, specifically RA signaling, as this data suggested there might be contributing factors intrinsic to IECs. We chose to establish a knockout cell line using the CRISPR/Cas9 system, given its affordability and efficiency compared to other in vitro models, and used it to study the effects of RAR⍺ ablation in IECs. Thus, our hypothesis was that RA signaling regulates the expression of lymphokines and other immune mediators (e.g., TSLP) by IECs, which then modulate the intestinal immune compartment. We hypothesized TSLP could be contributing to the decrease in CD103+ DCs as it is an important cytokine involved in TH2-type immunity and plays a key role in the maintenance of peripheral CD4+ T cell homeostasis by modulating the activation/maturation of myeloid cells. We used the CRISPR/Cas9 system to examine the effects of RARα ablation and its role in regulating intestinal epithelial TSLP expression. We found that TSLP expression is controlled by RARα in IECs where it may act as a repressor of TSLP promoter transactivation. This suggests an important role for RA signaling on myeloid/T cell function via effects on TSLP gene expression.

abstract: The present study explored the phenomenon of living with military-related (M-R) Posttraumatic Stress Disorder (PTSD). What it is like and what it means for the (M-R) traumatized person to live with PTSD in everyday living was the research question. The study follows the hermeneutic phenomenological methodology as developed by Max van Manen (1997). The study was conducted both in Canada and in Israel: Thirteen male military veterans, five Canadian former peacekeepers in Bosnia or Somalia (six to twelve years after traumas) and eight Israeli veterans who took part in Israel's wars and/or military operations (six to thirty six years after the traumas), participated in the study. Hermeneutic phenomenological interviewing was the study's main method for collecting lived-experience descriptions. With each of the Canadian participants, a two hour interview was conducted, and with each of the Israelis - one to seven hour interviewing, in one to three meetings. The interviews were taped, transcribed, and translated (if necessary). Phenomenological thematic reflection as a way to uncover the meaningdimensions of the phenomenon was done by researcher, sometimes in collaboration with the participants. Etymological reflection was another method used to disclose the meaning of the phenomenon. A line-by-line thematic analysis of the lived experience descriptions was done, as well as a wholistic approach. Four major themes emerged from the inquiry: trauma remembering, the encounter with death, being hypervigilant in an unsafe world, and being another to oneself and others. It is hoped that the research will contribute to mental health care of (M-R) traumatized persons, as well as to a better understanding of the phenomenon in society at large.

abstract: Remyelination is the generation of new myelin sheaths after injury, and is accomplished by oligodendrocyte precursor cells (OPCs) that proliferate, migrate, and differentiate into myelin-forming oligodendrocytes. A number of lesion-associated factors have been identified that interfere with the remyelination response. Chondroitin sulfate proteoglycans (CSPGs) are a family of extracellular matrix molecules that provide structural rigidity to tissues and act as signalling molecules to neurons and glia in the developing nervous system. After injury, CSPGs become highly upregulated by astrocytes as part of the glial scar and restrict axonal regeneration. The role of injury-induced CSPG deposition on OPCs and remyelination is far less understood. In this thesis, I characterized a potent inhibitory phenotype of murine OPC adhesion and process outgrowth cultured on CSPGs in vitro. I explored the various mechanisms underlying this inhibitory response, including candidate receptors, downstream signalling molecules, and structural ligands on CSPGs through selective enzymatic degradation. I screened 245 orally available, Health Canada approved medicines for their ability to overcome OPC process outgrowth in the presence of CSPGs, and found a persistent inhibitory phenotype for all drugs tested. Lastly, I assessed the utility of a novel CSPG synthesis inhibitor, fluorosamine, and found that it reduced CSPG synthesis by astrocytes, resulting in a more permissive environment for OPC growth in vitro. Following experimental demyelination with lysolecithin in vivo, fluorosamine treatment reduced the deposition of CSPGs and enhanced OPC maturation and remyelination. Altering the inhibitory microenvironment after injury may be beneficial for promoting repair in a number of neurological diseases.

abstract: English Language Learners (ELLs) are an increasing presence in Canadian schools. However, little research has been done to examine certain skills of ELL students, such as written expression. The purpose of this study was to explore contributing factors to ELL students’ writing quality. The present study gathered written samples from ELL students from Western Canadian elementary charter schools. Students’ expressive vocabulary was also assessed using a norm-referenced measure. Writing samples were Factors such as vocabulary, printing quality, and spelling skills will were considered in this study. It was determined that vocabulary was a significant contributor to overall writing quality of ELL students. More specifically, lexical reach and vocabulary diversity were the greatest contributors. These findings have important implications for educators and school districts to consider when teaching written expression to ELL students, ensuring they receive equitable education.

abstract: Dendritic cell (DC) interaction with infectious prions (PrPSc) represents an important part of prion pathogenesis. Previous studies have shown that DCs are likely among the first immune cells to interact with PrPSc after oral exposure. This study looks at the initial exposure of PrPSc on DC activation by measuring TNFα and IL-12 production. There was no significant production of TNFα or IL-12 by bone marrow derived DCs (BMDC) after exposure to PrPSc infected brain homogenate, however, BMDCs had lower capacity to produce IL-12 after secondary stimulation with LPS. Semi-purified PrPSc also did not activate BMDCs, however, the recombinant MoPrP 23-231 and MoPrP 90-231 elicited TNFα and IL-12 production. These results may not be surprising since PrPSc closely resembles cellular PrPC and therefore, DCs recognized PrP in brain homogenates as self-antigens. However, MoPrP 23-231 and MoPrP 90-231 were recognized as foreign antigens since the proteins were produced in bacteria.

The work involved ice core drilling and collection of snow and fiord water samples. These have been the subject of conductivity (SEC)-salinity, 180, tritium, ice density and ice texture analysis. Accorct;ng to these parameters, ten ice types have been identified (Tables 5.12A and 5.12B) and each is found in or adjacent to the ice shelves and plays a role in their growth and structure (Fig. 5.40). Ward Hunt Ice Shelf is largely composed of three types of basement ice, which are the product of a sequence of processes which transform first-year sea ice to very old multiyear sea ice, in the absence of 18 O depleted meltwater. Milne Ice Shelf is largely composed of glacier tongues which flowed into and coalesced in Milne Fjord. The ice tongues and the basement ice acted as stable platforms for further ice shelf thickening through snow and ice accumulation. The latter involved percolation and refreezing of meltwater, with attending isotopic homogenization and enrichment from snow o values of -31 .0 0 loo to ice o values of -29.2 0 loo. During periods of negative surface mass balance, meltwater accumulates in meltwater lakes in the summer and refreezes to trough ice (o 18 o, -24.0 °100) in the winter. The ice shelves act as dams creating stratified conditions of freshwater (runoff) overlying seawater (Arctic surface water and/or Atlantic water) in Disraeli Fjord and inner Milne Fjord. The freshwater just above the halocline is supercooled; frazil ice forms and floats to the surface and accretes as a freshwater fjord ice with a o1 8 O value of -26.0 0 loo. During a climatic amelioration ea. 250012000 BP to ea. 1600 BP, an extensive freshwater flow beneath Ward Hunt Ice Shelf led to the accretion of a freshwater, 18 O depleted ice (-25.5 0 loo), which originated with frazil ice growth, and is now sandwiched between basement ice layers. The conductivity and o18o value of this ice indicates that frazil ice growth and accretion at the bottom of the ice shelves does not lead to "brackish" basement ice growth as suggested by Lyons et al. (1971). The re-entrant (or multiyear) sea ice that has grown at the front of Milne Ice Shelf is the closest analogy to "brackish" ice. In this ice, salinity ranges from zero to 2.84 °100, and o18 o ranges from -23.8 0 loo to -4.2 0 loo. This variation, which is manifested as seasonal and 10 year fluctuations of salinity and 18 0, arises from similar variation in the water beneath the ice. Each summer, 180 depleted meltwater dilutes the underlying seawater. At the end of the summer a low salinity-low 180 ice freezes first and is followed by higher salinity-higher 180 winter ice. The annual and 10 year stratification leads to an interfingering of fresh, brackish and saline ice which resembles "brackish ice". Re-entrant ice is influenced by 18 O depleted meltwater, but basement ice is not. The ice shelves have experienced two periods of expansion and two periods of wastage. Re-entrant ice, which precedes basement ice growth, is forming during the present period of ice wastage. If the climate deteriorates, re-entrant ice might be succeeded by basement ice growth and further ice shelf expansion and thickening.

abstract: Social media is an important part of our lives. It is hard to ignore the role of social media in our everyday lives and during disastrous events. During emergencies, emergency personnel need to make strategic decisions in a short amount of time, coordinate actions and prioritize tasks. Social media can be a powerful source of information that comes directly from the public; it can reflect public sentiment, needs, and questions. In this research, I performed an interview study to find the use cases and challenges that emergency-related organizations encounter when dealing with social media. The findings reveal the needs of practitioners for designing social media monitoring tools to help them find the information they need. One of the main challenges for practitioners is that commercial tools are not designed for emergency response, and academic approaches do not consider their requirements. This dissertation brings insight into the design of expert-informed machine learning solutions for identifying relevant information from social media by following a human-centered design approach. By actively being involved with emergency practitioners throughout three years, I designed, developed, and evaluated a social media monitoring tool for emergency response. The evaluation results show the effectiveness of bringing analysts into the classification loop to train and get feedback to machine learning classifiers. It also shows that analysts would like to combine the training tasks with their response tasks. Another aspect of this research is exploring the significance of various categories of features and machine learning algorithms and automatically identifying situational awareness information in different emergency event datasets. Results show that significant features vary across different events which indicates that training should happen during the event.

abstract:
Inner city suburbs throughout North American cities are currently being pressured by the constantly increasing demands for expansion of the Central Business Districts. There is a growing desire by residents of these communities to retain what are essentially vital, rehabilitating, socially satisfying neighbourhoods. The objective of this Masters Degree Project was to test the hypothesis that citizens can be motivated, organized and educated to establish goals and objectives, to identify and design solutions to problems and set guidelines for the conservation and future development of such connnunities.
A thirteen month study was conducted in the Rideau-Roxboro community of Calgary, Alberta, 1976/77. An overall "continuous" planning process model was designed as were processes and techniques for the animation and education of the community and a two-way connnunications system to allow for an on-going feedback component. The community was studied in detail and its objectives and concerns identified and analysed. A community plan, articulated in a Policy Report, reviewed the existing conditions and made policy recommendations for the foreseeable future.
Three development proposals about to impact upon the community were analysed. Alternative solutions were formulated and specific criteria generated for evaluation of the alternatives. An adaptation of the Delphi forecasting technique proved superior to traditional rating and scaling devices as a means to include citizen input in the evaluation process.
The role and responsibilities of the connnunity planner were identified and an assessment made of the effectiveness of the Rideau-Roxboro planning exercise in advancing the cause of citizen participation in community decision-making.

abstract: Bacterial biofilms are surface adhered communities of microorganisms encased in a protective polysaccharide layer. These resilient structures present significant challenges for effective host immune cell clearance or clinical interventions, frequently resulting in recurrent infections in cattle, humans, and other animals. Fusobacterium necrophorum and Porphyromonas levii are two species of anaerobic, Gram-negative, opportunistic pathogens that have been described as etiological agents in a variety of necrotic, recalcitrant infections. With antimicrobial resistance on the rise, it is important to elucidate the reasons why biofilm-associated infections are so difficult to eradicate. Neutrophils are critical first responder cells that are recruited to a site of bacterial colonization to initiate the inflammatory response. In this dissertation research, an in vitro system for the growth of mixed-species anaerobic biofilms was employed to investigate bovine neutrophil responses to biofilm bacteria compared to planktonic cultures of the same two species. Neutrophils exposed to biofilm soluble factors generated reduced oxidative and chemotactic responses compared to neutrophils exposed to planktonic bacteria-generated products. Ultra-filtration revealed that a <3kDa molecule is differentially expressed in the bacterial supernatants and allows biofilm-bacteria to inhibit neutrophil responses. Intensive heat, protease, lipase, or nuclease treatment of the <3kDa fractions prior to exposure to bovine neutrophils did not alter the differential oxidative responses. This led to an investigation of small, heat stable compounds and our results suggest that the accumulation of protoporphyrin IX in the biofilm mode of growth attenuates neutrophil chemotaxis and reactive oxygen species production. This work provides evidence for a mechanism by which these biofilm bacteria evade host immune cells and understanding such mechanisms is important to reduce the persistent inflammation and negative clinical outcomes associated with chronic biofilm-mediated disease.

abstract: A fake real quadratic order is defined based on an imaginary quadratic field and a prime p but behaves similarly to real quadratic orders. Two conjectures regarding fake real quadratic orders are discussed in the thesis. The first one is the Cohen-Lenstra heuristic. Our computation showed that for fixed p, the proportion of fake real quadratic orders for which the odd part of the class number is one converges to C=0.754458..., which equals exactly the proportion of real quadratic fields for which the odd part of the class number is one. The second one is the Ankeny-Artin-Chowla conjecture, which states that D∤b where b is the second coefficient of the fundamental unit in the real quadratic field Q(√D). No counterexamples have been found in real quadratic fields but we found numerous counterexamples in fake real quadratic orders and this is evidence that the conjecture is false for real quadratic fields.

abstract: Scene parsing is to densely label the pixels in an image with the semantic categories. In this thesis, we present a scene parsing framework which can work on both images and point clouds. To this end, we develop two separate pipelines for images and point clouds. For point clouds, a coarse segmentation is implemented to obtain an initial distribution for the objects. For images, superpixel segmentation is implemented and StructureTransfer is carried out. StructureTransfer is a model to find similar regions across scenes. The two pipelines converge at the inference step. Several novel potentials, representing point cloud constraints and StructureTransfer scores, are introduced into a traditional Markov Random Field (MRF) for the inference. The parsing accuracy of the proposed method is close to state-of-the-art algorithms on images. With the point clouds, the accuracy is significantly enhanced. The proposed framework shows remarkable prospect in real-world applications.

abstract: Bioanalytical techniques that can be employed to obtain health-relevant information from biological fluids (i.e. erythrocytes) are urgently needed to gain new insight into the bioinorganic chemistry of non-essential metal species in the human body. To this end, a metallomics method was developed to probe the interaction of Cd2+, Hg2+, CH3Hg+ and thimerosal in the erythrocyte based on the direct analysis of erythrocyte lysate by size exclusion chromatography coupled on-line to an inductively coupled plasma atomic emission spectrometer (SEC-ICP-AES). This method development entailed systematic investigations into the sample preparation of the erythrocyte lysate (i.e. filtration to remove cell debris) as well into the identification of the ideal stationary phase and mobile phase. Filtering (0.45 μm pore-size Millex syringe-driven filers) and diluting (5-fold with corresponding buffer) resulted in the most consistent and reproducible results for the analysis of the erythrocyte lysate. A Superdex 75TM Increase 10/300 GL (300 x 10 mm I.D., 8.6 μm particle size) column that offers a fractionation range of 3 – 70 kDa was best suited for the separation of the major Cu, Fe and Zn metallospecies that are present in the erythrocyte lysate. 100 mM Tris(hydroxymethyl)-aminomethane  (Tris) buffer (pH 7.4) was identified as the optimal mobile phase as it allowed for the separation of all the metallospecies of interest and gave the highest metal recovery of all the mobile phases (Zn: 95.8 ± 2.8% , Fe: 88.0 ± 7.2%). This developed metallomics method was subsequently employed to probe the comparative interaction of Cd2+, Hg2+, CH3Hg+ and thimerosal in erythrocyte lysate over a 6 h time period. The results that were obtained at time points ≥2 h revealed that ~85% of Cd2+ weakly interacted with hemoglobin (Hb), while ~13% eluted as (GS)xCd and ~2% bound to a ≥70 kDa Cd-binding protein. In contrast, ~6% of Hg2+ co-eluted with Hb at all time points, while ~94% eluted as (GS)xHg. The results for CH3Hg+ showed that ~5% of Hg co-eluted with Hb (constant over the 6 h time period), while for thimerosal (THI), this percentage gradually increased to 12% over the 6 h time period. The remaining Hg eluted as GS–HgCH3 and GS–HgCH2CH3, respectively. The co-elution of Hg with Hb – regardless of whether Hg2+, CH3Hg+ or THI was added – indicates that these interactions may adversely affect the function of Hb. The results demonstrate that the developed metallomics tool provided is ideally suited to obtain new insight into the bioinorganic chemistry and the toxicology of non-essential metal species within erythrocytes.

Equations of state

abstract: An inconsistency in thermodynamic property prediction using the Trebble- Bishnoi equation of state was recently identified by scientists at the Shell research center in Amsterdam. Specifically, it was found that the Trebble-Bishnoi equation of state predicted negative values of isochoric heat capacity and imaginary values for speed of sound at extremely low temperatures. Subsequent investigation has led to the conclusion that any temperature dependence whatsoever in the covolume term of van der Waals type equations will re~ult in anomalies in the predicted thermodynamic properties of pure fluids at extreme conditions. This work presents a discussion of the implication of temperature dependence in the Trebble-Bishnoi equation of state parameters and describes a modification to the equation in which temperature dependence is completely removed from the covolume term. By altering the temperature dependence in the attractive parameter, it is possible to correlate liquid-vapor phase behaviour with the modified equation more accurately than with the original equation, and the inconsistency has been corrected. The _modified equation was examined further through the calculation of eight thermodynamic properties in liquid-vapor regions over a very broad range of temperature and pressure. Predictions of second virial coefficients, internal energy, enthalpy, entropy, isobaric and isochoric heat capacities, speed of sound, and Joule-Thomson coefficients were compared to experimental data and to properties calculated using the Peng-Robinson equation of state. Results from the modified equation are of reasonable accuracy and are comparable to those obtained from the Peng-Robinson equation. No thermodynamic anomalies were detected for either equation of state apart from the fact that an infinite value for isochoric heat capacity is not predicted at the critical point. Having developed a satisfactory model for describing liquid-vapor regions, it was desirable to extend the equation of state to pure solids so that consistent calculation of solid-vapor equilibria could also be achieved. Based on correct thermophysical constraints and utilizing solid heat capacity, solid density and heat of sublimation at the triple point, a methodology is presented for extending the use of the equation of state to pure solids. The methodology is tested through the predictions of PVT behaviour and isobaric heat capacities for solids from their triple points to very low reduced temperatures. It is found that there are no negative heat capacity predictions and that an equation of state with at least four parameters is required to provide good prediction of solid-vapor phase behavior. Also discussed is the estimation of binary interaction parameters for binary solid-supercritical fluid systems using classical equation of state mixing rules and a common flash algorithm.

abstract: Recently, the application of nanoparticles for enhancing oil recovery in carbonate reservoirs has received great attention from various researchers across the oil and gas industry. In contrast to sandstone reservoirs, carbonates are naturally neutral-wet or preferentially oil-wet. Understanding the mechanisms associated with wettability alteration of these reservoirs, especially to strongly water-wet, is of great importance during various stages of oil production. Altering the reservoir wettability towards water-wet enhances the spontaneous imbibition of water, resulting in improved oil recovery. In this study, a novel surfactant-free aluminum silicate-based nanofluid is synthesised and tested for its efficiency to alter the wettability of Austin Chalk carbonate rocks from oil-wet to strongly water-wet. Characterization techniques, such as SEM, BET, XRD, DLS, and Z-potential were conducted on the synthesized nanoparticles to confirm their surface identity, functionality, stability, and morphology. The prepared nanofluids from the synthesized nanoparticles were tested in comparison to brine for their EOR efficiency in carbonate cores. The EOR performance was investigated by interfacial tension (IFT), contact angle, spontaneous imbibition, and displacement tests. The results showed that compared to brine alone, nanofluids could notably alter the rock wettability from oil-wet to water-wet. To confirm this, a core flooding test was performed which further reiterated the capability of the aluminum silicate-based nanofluids to act as effective EOR agents in hydrocarbon carbonate reservoirs by recovering an additional 9.23% of residual oil in comparison to low-salinity brine.

abstract: Chronic Wasting Disease (CWD) is a fatal neurological disease affecting cervids caused by prions. Infected cervids shed the CWD prion in bodily fluids and excrement, contaminating the environment and creating an agricultural and ecological calamity. Preclinical antemortem CWD testing method is demanded by CWD risk management programs.  In vitro PrP-conversion assays have been developed as potential tools for such an approach with increasing sensitivity for prion detection. However, no method has been routinely employed thus far. Timing recombinant-PrP conversion into amyloid fibrils, seeded by elk CWD prion, as a diagnostic method is presented herein. The assay, termed “RePLICA”, is at least as sensitive for detecting elk CWD in brain tissues as Tg(CerPrP-M132)1536+/- and Tg(CerPrP-E226)5037+/- mouse bioassay models. The assay performs within a period of 35 hours, is consistently reproducible, and functions on elk brain and tonsil tissues. There are indications RePLICA has the potential to titre CWD infectivity.

There is a need for practical tools to facilitate exercise, an important component of type 2 diabetes (T2D) management. Thesis objectives included: 1) determine the accuracy of the MyWellness Key (MWK) accelerometer in people with T2D; 2) complete a systematic review and meta-analysis of resistance band training (RBT) in T2D; and 3) propose and initiate a randomized exercise trial utilizing MWK accelerometers and RBT.
The MWK accelerometer was validated against objective treadmill testing and physical activity diaries in people with T2D (n=35). The waist-mounted MWK was quite accurate at determining exercise volume and discriminating between exercise intensities, however the bra MWK consistently underestimated exercise intensity. The meta-analysis of seven trials showed that RBT non-significantly improved glycemic control and significantly increased strength in the lower, but not the upper, extremities in people with T2D.

abstract: Detection of biological agents by traditional bench-top instrumentation is insufficient for purposes of real time on-site analysis, which is imperative for biodefense applications. Unlike radiological and chemical warfare agents, sophisticated detection systems have not yet been designed for immediate sensing of biological agents. Development of field-deployable biosensors is a response to fulfill this gap, specifically, the demand for immediate recognition of samples of unknown origin requiring broad-based detection capabilities. Our research group has been pursuing this venture by creating an electrochemical biosensor that is able to detect the bacterial endotoxin, lipopolysaccharide (LPS), produced by gram negative bacteria. Our biosensor utilizes Toll-like Receptor 4 (TLR4) immunoproteins as the biorecognition element. These immunoproteins are surface immobilized via ternary alkanethiolate self-assembled monolayers (SAMs) deposited on polycrystalline Au surfaces. These SAMs possess a uniquely low interfacial resistance (? 1 k?) due to the presence of a Ferrocenyl-thiolate component, which mediates electron transfer from dissolved Fe(CN)64- to the underlying Au substrate. The work presented in this thesis focuses on the problem, and its subsequent solution, encountered with the SAM electrochemistry portion of the TLR4 sensor assembly. The issue was initially detected by false positive responses of the sensor in the absence of LPS-containing bacterial lysate, exhibiting an increase in resistance of similar intensity in both the absence and presence of heat-killed Salmonella typhimurium (HKST) bacterial lysate. The primary cause of the TLR4 sensor drift was determined here to be the instability of the Fc+ group, which is generated repeatedly during the mediation of the Fe(CN)64- oxidation process. This is consistent with past literature that alluded to the irreversible redox deactivation of the Fc+ group under non-optimal conditions. This problem was remedied in this work by replacing phosphate ions from the buffer solution by perchlorate, but as proteins such as TLR4 should be kept in neutral conditions, another solution was sought. This involved replacing the original Fc-thiol molecule (i.e., 11-mercaptodecyl-ferrocenylcarboxamide (Fc-amide)) with 11-(ferrocenyl)undecanethiol (FcC¬11).These novel ternary SAMs containing the stable FcC11 component were then used to prepare a new generation of TLR4-based sensors, which showed negligible drift and were able to reliably detect LPS from 0.0128 to 5000 µg/mL. This demonstrates that utilizing Fc-thiolate SAMs is now a viable method to prepare low-resistance biosensors for use as field-deployable systems.

abstract: Dentition is vital to our understanding of mammalian evolution. In this thesis, I use dental morphology as a basis for investigating various phenomena in mammalian dentition. First, I investigate the utility of shape, form, and linear measurement when differentiating species of the genus Mesodma – part of an early group of mammals known as the multituberculates. I found that shape and size metrics reveal different classifications of species. I conclude this chapter by suggesting these methods of differentiation should be investigated further along with the genus. Second, I investigate if cusp shape covariation across the premolar-molar boundary can highlight dental morphology covariance patterns that may contribute to the evolution of molarization in mammals. I found a significant difference in the cusp shape modularity among the two extant orders of hoofed mammals. I infer there are differences in the mechanism of molarization contributing to this differentiation. Further studies are required to infer a mechanism. The studies I present in these chapters showcase how dentition continues to provide important discoveries in the history of mammalian evolution.

abstract: The vaporization of Swan Hill Crude Oil in the displac ement process by enriched gas was investigated. This study mainly investigated the compositional effect and the displacement pressure effect on the interphase mass transfer when gas was introduced to mix with the crude oil at reservoir conditions. The study indicates that vaporization of c+ 5 material is directly proportional to the richness of the injected gas. Using ah enriched gas(SO mole% of c; ), the condensing drive vaporized about 40-50% of the c+ 5 from the crude oil after 2.5 pore volumes had been injected. The vaporization of the c+ 5 will decrease as the methane component increases in concentration in the injected gas. When the methane composition is increased to 95 mole%, the vaporization will amount to approximately 10% at an injected pore volumes of 2 . 5. Al so, this study indicates that displacement pressure has a dominating effect on the degree of vaporization. When the operating pressure is increased from 2,500 psia to 3000 psia ,the vaporization of the c+ 5 is increased from 32% to about 50% when an intermediate rich gas (37.32 mole per cent c+ 2 ) is used. In this study, composition of the twd phases at equilibrium were predicted, by a minimum free energy concept in conjuction with the modified Redlich-Kwong equation of state for the gas phase and the dilated Van Laar model for the liquid phase in the calculation of phase fugai cities as proposed by Prausnitz et al(l968) ~ The binary interaction constants or parameters for the heavy ends were calculated and adjusted based on the available compositional analysis of the equilibrium mixture of Swan Hill crude oil and injected gas at various gas oil mixing ratio. The predicted composition for the vapor and liquid in the equilibrium show an absolute deviation of less than 10% for the system mixture of Swan Hill crude oil and enriched gas at 2,500 psi and 225°F. In order to simulate the steady state displacement process, a multicell separation model was used. This model incorporates the constraint of constant volume for each cell and the option of fluid transport according to the phase mobility. Recovery calculated based on this simplified model shows a good agreement with avail able experimental data in the case of condensing gas drive. For condensing gas drive, two important factors are learned to be important: vaporization and condensation. Vaporization takes place for the heavy ends and condensation for the other components. Combination of these two mechanisms accounts for the high recovery in the order of 90 to 110% as experienced in the linear sand pack displacement test, where the methane composition used in the injected gas stream varies from 45 to 55 mole percent.

abstract: Recent technological advancements have led to unprecedented amounts of 3D data becoming available about the Earth. With this, technologies that facilitate the efficient integration and management of geospatial data are becoming increasingly important. Hierarchical partitionings of the surface of the Earth, known as Discrete Global Grid Systems (DGGS), have proven to be useful tools for integrating data on the Earth's surface; however, they have no native support for 3D data. Instead, a 3D version of this data structure is needed. An Earth-centric 3D DGGS that respects the spherical nature of the planet is desirable, but this approach introduces the problem of reduced cell size and compactness near the centre of the grid. In this thesis, we explore a particular class of refinement methods, which we term semiregular degenerate, as a potential solution to these issues. We propose both a modification of an existing 3D DGGS to improve its volume preservation properties and a general framework for extending any existing DGGS to the third dimension. We also derive a set of mapping functions that facilitate efficient encoding and decoding algorithms for both these methods. Grid properties and algorithm runtimes are evaluated quantitatively, and a series of use cases are used to evaluate the grid extension methodology by creating a 3D DGGS explicitly tailored for each example application.

abstract: Considerable attention has been given to characterizing the relationship between fluids and plate boundary fault systems at convergent margins, yet comparatively little is known about the hydrogeology of submerged transform boundaries. Following the 2012 M7.8 earthquake off western Haida Gwaii, an international scientific partnership was established between US and Canadian scientists to study the Queen Charlotte Fault – a ~1200 km transform fault between the Pacific and North American plates, where ~ 900 km lies offshore. Scientific expeditions onboard the R/V John P. Tully in 2015 and 2017 identified numerous water column anomalies (i.e seeps), mud volcanoes, microbial mats, and indicators of seabed fluid flow along the QCF. Analyses of pore fluids recovered from the 2017 cruise revealed abundant overprinting signatures of carbonate precipitation, anaerobic oxidation of methane, and particulate organic carbon sulfate reduction processes that dictate the chemistry of the observed pore waters. These chemical processes promote the formation of carbonates and iron sulfides that fuel microbial mats and diverse chemosynthetic communities at the seafloor. Analyses of water isotopes and chloride concentrations suggest that certain locations in proximity to the QCF may be influenced by meteoric water, or some currently unknown isotopic depletion process. Strontium isotopes reveal a non-radiogenic strontium signature at depth, suggesting basalt-fluid interaction and/or a diagenetic overprinting of sedimentary ash alteration. Fluids collected from CTD casts in the southern portion of the QCF suggest that actively seeping fluids have been influenced by the formation of gas hydrates. Taken together, the results presented in this investigation imply a significant flux of hydrocarbons (primarily methane) is occurring from buried sediments, in combination with high productivity in the water column contributing organic material during sedimentation. A general overall signature of authigenic carbonate precipitation is found at most sites along the entire length of the QCF, acting as a major sink for calcium, magnesium, and strontium between the ocean and seafloor sediments. Migration of fluids within the QCF is complex and varied from the northern region to the south – this study provides an overall preliminary insight to the inner workings of the QCF that merit ongoing investigation.

abstract:
In this thesis, I study the space complexity of the implementation of test-and-set and renaming problems from atomic multi-reader/multi-writer registers in distributed synchronous systems with n processes.
Previously, Giakkoupis and Woelfel as well as Styer and Peterson showed that at least Omega(log n) registers are required to implement one-shot test-and-set objects. First, I show a deterministic obstruction-free test-and-set algorithm using O(sqrt n) unbounded registers. Next, I present a deterministic obstruction-free implementation of a one-shot test-and-set object from Theta(log n) registers of size Theta(log n) bits, which closes the gap between the upper and lower bound.

The problem of assigning unique names to processes from a set of size f(k) is called f-adaptive renaming, where k is the number of participating processes. Long-lived f-adaptive renaming allows each process to acquire and then release a name any number of times. One-shot adaptive renaming allows each process to get a name at most once. Let f: {1, ... ,n} -> N be a non-decreasing function satisfying f(1) <= n-1 and let d = max{x | f(x) <= n-1}. I show a lower bound of d + 1 registers for any non-deterministic solo-terminating long-lived f-adaptive renaming task. Furthermore, I observe that, this is a tight lower bound for long-lived (k+c)-adaptive renaming.  However, for any non-deterministic solo-terminating one-shot (k+c)-adaptive renaming, I prove a lower bound of floor{2(n - c)/(c+2)} registers. I also provide two one-shot renaming algorithms: a wait-free one-shot (3k^2/2)-adaptive renaming algorithm from ceil{sqrt n} + 1 registers, and an obstruction-free one-shot f-adaptive renaming algorithm from min{n, x | f(x) >= 2n} + 1 registers.

abstract: Since 2014, several democratic States across the world have descended into crisis under Far Right populist leaderships that vilify immigrants to forward their ethnonationalist, religio-political, and masculinist agendas. I studied the ways in which pro and anti-immigration social movement discourse was shaped, reified, and promoted online. I historicised and examined online discourse pertaining to four social movements across two distinct national contexts, and across the political aisles in each context: Pro-immigration movement in India (anti-CAA/NRC); Anti-immigration movement in India (pro-CAA/NRC); Pro-immigration movement in USA (Families belong together protests to Abolish ICE); Anti-immigration movement in USA (Build the wall). I conducted a multimethod study beginning with a Qualitative Content Analysis (QCA) (6,000 tweets) followed by a Critical Discourse Analysis (CDA) of 600 tweets. Findings indicated that the anti-immigration movement discourse in both countries: propagated nationalistic emotion via structured weaponisation and counter-framing of “Love” for one’s country; displayed a masculinist spatial rejection of women’s dissent and support for Statist brutalities against dissidents; and engaged in historical revisionism in favour of majoritised groups, re-historicising to discursively establish masculinist hindu-nationalism in the Indian context and white supremacism in the US context. Whereas, the pro-immigration movement discourses in both countries: highlighted women led sit-ins; claimed a fight for the “soul” of India and the USA; actively historicised their own movements as well as Statist brutalities faced by immigrants and activists; and highlighted erasure of certain marginalised groups from mainstream movement discourse. Simultaneously, the use of social media technologies and tools in order to forward movement discourse were discussed in relation to each movement, embedded alongside the analysis of each movement's discourse. My work uncovers the networked ways in which social media technologies impact social movement discourse, especially in the Global South, and will contribute to social movement scholarship by employing a Southern imaginary to dismantle academic tendencies to use theories from the Global North to study data from the Global South.

abstract: One challenge facing Western Canada is the limited capacity to transport bitumen through pipelines. Bitumen has a high density and viscosity that both exceed pipeline specifications. It must be diluted for transport, but the diluent occupies a capacity that would otherwise be available for the bitumen. One possible solution is to reduce the amount of diluent by decreasing the density and viscosity of the bitumen through a combination of de-asphalting and visbreaking processes. Visbreaking reduces the viscosity of the oil, however, if carried too far, this process can destabilize the oil (cause asphaltene precipitation and coke formation). De-asphalting decreases the oil density and can allow more intensive visbreaking without destabilizing the oil. These processes can be applied to both bitumen and vacuum bottom feeds. In all cases, it is necessary to predict the product properties and stability to optimize the process design. This thesis aims to measure and model the effect of visbreaking on the density, viscosity, and stability of a bitumen, a vacuum bottom, and a de-asphalted oil. Each oil was visbroken at two different severities (combinations of temperature and residence time) in an in-house continuous visbreaker. The feeds and their products were separated into distillates, saturates, aromatics, resins, and asphaltenes, and the properties (molecular weight, density, viscosity, and solubility) of each fraction were measured. Previously developed correlations for molecular weight, density model parameters, viscosity model parameters, and solubility parameters were updated. The density of the oils was determined with a volumetric mixing rule and their viscosity with the Expanded Fluid viscosity model. Their stability versus asphaltene precipitation was determined with the Modified Regular Solution phase equilibrium model. The average deviation of the modelled densities and viscosities were 2 kg/m³ and 19%, respectively. The average deviation in the modelled onset of asphaltene precipitation (solvent content at which precipitation first occurred) was 4.4 wt% n-heptane. The average deviation of the modeled asphaltene yield (mass of precipitated asphaltenes divided by the mass of feed oil) was 2.3 wt%.

abstract: The economic use of offer restatements in the restructured Alberta electricity market can be seen as an exercise of market power. By using this mechanism to alter their energy offer, a supplier can withhold supply from the market leading to a significant price effect. This thesis examines this behaviour in the first half of 2006. Evidence is provided that the locking restatement in particular is used to economically withhold capacity from the market. It is shown that in some instances the impact on pool price from this withholding of capacity is more than $300/MWh and the associated transfer of wealth from load to supply, more than 3 million dollars in a single hour. It is also shown that this exercise of market power is carried out repeatedly during the six month period examined and a large fraction of the instances can be attributed to a single participant.

abstract: The dominant mechanism of enhanced heavy oil recovery by chemical flooding is studied by conducting various chemical slug injections into a two-dimensional physical model. A total of sixteen tests including seven single-slug tests, seven two-slug tests and two tests with chemical slug alternated with air slugs were conducted to test the contribution of alkaline, surfactant, polymer and their combinations to enhanced heavy oil recovery. The relationship between the tertiary oil recovery and the pressure drop of the seven single-slug floods was analyzed, and it was discovered that the two have a good correlation. Comparison of the tertiary oil recoveries of different chemical slug tests shows that the improved recovery for the heavy oil used in this study is mainly due to the plugging of water channels, or the reduction of water mobility. The results of two-slug tests show that after regular alkaline/surfactant/polymer flooding, the second polymer slug injection can recover more oil, if a water slug injection is applied between the two chemical slugs. Experimental results and conclusions were further studied in the field application of polymer flooding, based on simulation results using actual geological and reservoir data and the production history data from Pelican Lake reservoir.

abstract: In this thesis, we present three innovations that can be used to simulate quantum dynamics on both quantum and classical computers. Our primary innovation is an efficient quantum algorithm for simulating time-dependent Hamiltonian evolution of general input states on a quantum computer. Given conditions on the smoothness of the Hamiltonian, the complexity of the algorithm is close to linear in the evolution time, and therefore is comparable to algorithms for time-independent Hamiltonians. In addition, we show how the complexity can be reduced by optimizing the time steps. The complexity of the algorithm is quantified by calls to an oracle, which yields information about the Hamiltonian. In contrast to previous work, which allowed an oracle query to yield an arbitrary number of bits or qubits, we assign a cost for each bit or qubit accessed, revealing hitherto unnoticed simulation costs. We also account for discretization errors in the time and the representation of the Hamiltonian. This work is enabled by our development of a decomposition scheme based on Lie-Trotter- Suzuki product formulae for ordered operator exponentials. We show, by counterexample, that Lie-Trotter-Suzuki approximations may be lower order than expected when applied to problems that have singularities or discontinuous derivatives of appropriate order. We address this problem by presenting a set of criteria that is sufficient for the validity of these approximations, prove convergence and provide upper bounds for the approximation error. We also provide a new analysis of the evolution of quantum adiabatic systems in this thesis. Our work contains the tightest upper bounds that are currently known, and the first tight lower bounds, for the error in the adiabatic approximation applied to fixed Hamiltonians in the limit of slow evolution. We use our results to address the Marzlin- Sanders counterexample Hamiltonian. Specifically, we provide sufficiency conditions for the validity of the adiabatic approximation and demonstrate that the Marzlin-Sanders counterexample fails to satisfy them. We also find a new class of time-dependent Hamiltonians that are related to the Marzlin0Sanders counterexample Hamiltonian, but nonetheless obey the adiabatic approximation for sufficiently slow evolutions.

abstract:
The aim of this research is to use a novel approach with less technical and analytic limitations in liquid solvent-bitumen diffusion studies. Taylor dispersion technique has been selected in this work due to its convenient short run-time experiments and reliable data analysis to find molecular diffusion coefficients in hexane-bitumen system.
For the first time, the infinite dilution molecular diffusion coefficients of bitumen in hexane were measured in both cases of presence and relative absence of asphaltene particles in the solution. As the first result, polydisperse nature of bitumen is clearly revealed. Results were compared with common predictive tools and the most reliable correlation is proposed. Also, it is found that asphaltene particles presumably have surface charge in hexane solvent.
Moreover, through concentration dependency investigations it was found that the molecular diffusion coefficients monotonically decrease as the viscosity of mixture increases within the concentration range studied.
In conclusion, Taylor dispersion technique showed a great potential in diffusion studies of liquid solvent-bitumen systems.

abstract: The study of Diophantine equations, and in particular the erroneously-named Pell equation, has a long and intriguing history.  In this work, we investigate solutions to the Pell equation and to a closely related quantity called the fundamental unit.  Though it is somewhat simple to show these equations have non-trivial solutions, finding unconditionally correct solutions and being able to express them is extremely challenging, both from a theoretical and a computational perspective.  We develop improvements to the algorithm presented by de Haan, Jacobson, and Williams [21, 22] which unconditionally verifies the regulator of a real quadratic number field and refinements to the concept of a compact representation of a quadratic integer, originally given by Buchmann, Thiel, and Williams [12].  In addition, we consider the well-known applications of this theory to principal ideal testing, finding integer points on elliptic curves, finding solutions to Diophantine equations, and some particular cryptographic applications.
