description: An immense quantity of hydrocarbon fuel is trapped in the fractured reservoirs, which is challenging to recover due to a number of issues such as heterogeneity of the reservoir’s properties, higher permeability of fractures than that of the matrix, and multiphase flow through the fractures. On average, the recovery of oil from these reservoirs is relatively low and there is a requirement to improve the performance of recovery processes in these systems. The research documented in this thesis deals with multiphase flow, in particular parallel flow of oil and water, in fractures, modelled as a single narrow gap Hele-Shaw cell. The effects of additives such as polymer, surfactant, and rod-like nanoparticles have been examined to determine how they impact the nature of the interfaces between the oil and water and the amount of oil displaced from the gap. Differential pressure, flow rates and images of the flow structures were acquired to provide a basis for both quantitative and qualitative analyses of the flows. In the case of co-injection of water and oil, different flow structures observed changed with phase flow rates – oil entrapment occurred in several forms including trapped connected oil as well as irregular and immobile droplets. The relative permeability and hysteresis observed in the experiments demonstrated the dependence of the flow on the direction of wetting phase saturation change. Surfactant (sodium dodecyl sulfate) addition to the water revealed that with the associated interfacial tension reduction, oil displacement improved and oil droplets formed at the oil-water interface. The addition of polymer (polyethylene oxide) to the water raised the viscosity of the aqueous phase which in turn improved the displacement of oil. Another key observation was the adsorption of polymer on the plates of the Hele-Shaw cell which changed the wettability of the plates leading to enhanced oil displacement. The addition of cellulose nanocrystals (CNC) to the water significantly improved oil displacement due to viscosity enhancement of the aqueous phase as well as reduction of the interfacial tension. Microscope observation also revealed the formation of a microemulsion adjacent to the oil-water interface.

description: We report that upon excitation by a single pulse, the classical harmonic oscillator immersed in classical electromagnetic zero-point radiation, as described by random electrodynamics, exhibits a quantized excitation spectrum in agreement to that of the quantum harmonic oscillator. This numerical result is interesting in view of the generally accepted idea that classical theories do not support quantized energy spectra.

description: We reexamine, within the nonrelativistic constituent quark model (NRCQM), a recent claim that the current data on the strangeness form factors indicates that the uuds\bar{s} component in the proton is such that the uuds subsystem has the mixed spatial symmetry [31]_X and flavor spin symmetry [4]_{FS}[22]_F[22]_S, with \bar{s} in S state (configuration I). We find this claim to be invalid if corrected expressions for the contributions of the transition current to G_A^s and G_E^s are used. We show that, instead, it is the lowest-lying uuds\bar{s} configuration with uuds subsystem of completely symmetric spatial symmetry [4]_X and flavor spin symmetry [4]_{FS}[22]_F[22]_S, with \bar{s} in P state (configuration II), which could account for the empirical signs of all form factors G_E^s, G_M^s, and G_A^s. Further, we find that removing the center-of-mass motion of the clusters will considerably enhance the contributions of the transition current. We also demonstrate that it is possible to give a reasonable description of the existing form factors data with a tiny probability P_{s\bar{s}}=0.025% for the uuds\bar{s} component. We further see that with a small admixture of configuration I, the agreement of our prediction with data for G_A^s at low-q^2 region can be markedly improved. We find that without removing CM motion, P_{s\bar{s}} would be overestimated by about a factor of four in the case when transition current dominates. We also explore the consequence of a recent estimate reached from analyzing existing data on \bar{d} -\bar{u}, s +\bar{s}, and \bar{u} + \bar{d} - s -\bar{s}, that P_{s\bar{s}} lies between 2.4-2.9%. It would lead to a large size for the five-quark system and a small bump in both G_E^s+ηG_M^s and G_E^s in the region of q^2<=0.1 GeV^2 within the considered model.

description: Hot stamping is a well-established and frequently used manufacturing process in automotive body construction. The number of components manufactured in this way is continuously increasing. Hot stamping is used to produce components with a completely martensitic structure, resulting in high strength and hardness. These components are mainly used in safety-relevant areas of the passenger cell, such as the A-pillar, B-pillar, tunnel and sill. For hot-stamping processes, it is necessary to austenitize the blanks. Heating the sheet metal up to 930 °C in a furnace is very energy-intensive. In large-scale industrial applications, the sheets are generally heated in gas-fired roller hearth furnaces up to 60 m long. Apart from the poor energy balance and the high CO2 emissions of such furnaces, they are associated with high investment and maintenance costs, large space requirements and a long heating time. Rapid heating by means of the Joule effect and direct current instead of alternating current offer an energy-efficient and environmentally friendly alternative for sheet metal heating. Therefore, this technology can make a major contribution to environmental protection and resource saving. Within the scope of this work, parts were rapid-heated and subsequently hot-stamped by means of a novel heating system based on direct current with energy savings of up to 80 %. Using electricity guarantees a good CO2 balance. In addition, resistance heating with a new type of DC-heating system and an adapted process chain is compared with conventional furnace heating. In thermographic images and microstructural examinations of the hot-stamped parts, it can be demonstrated that this direct-current technique is well suited for achieving homogeneous hardness and strength in the whole sheet metal. Thus, this new heating system can enhance the efficiency of the hot-stamping technology.

Can a Long Nanoflare Storm Explain the Observed Emission Measure Distributions in Active Region Cores?

description: All theories that attempt to explain the heating of the high temperature plasma observed in the solar corona are based on short bursts of energy. The intensities and velocities measured in the cores of quiescent active regions, however, can be steady over many hours of observation. One heating scenario that has been proposed to reconcile such observations with impulsive heating models is the "long nanoflare storm," where short duration heating events occur infrequently on many sub-resolutions strands; the emission of the strands is then averaged together to explain the observed steady structures. In this Letter, we examine the emission measure distribution predicted for such a long nanoflare storm by modeling an arcade of strands in an active region core. Comparisons of the computed emission measure distributions with recent observations indicate that that the long nanoflare storm scenario implies greater than 5 times more 1 MK emission than is actually observed for all plausible combinations of loop lengths, heating rates, and abundances. We conjecture that if the plasma had "super coronal" abundances, the model may be able to match the observations at low temperatures.

The epidemiology of methamphetamine use among street youth and injection drug users
Creators: name: Marshall, Brandon David Lewis
Publisher: name: University of British Columbia
Year: 2010

description: Background: Given the limited understanding of the epidemiology of methamphetamine (MA) use among street-involved youth and injection drug users (IDU), this thesis sought to: systematically characterise the evidence base demonstrating associations between MA use and adverse health outcomes among young people; examine the incidence and predictors of MA injection initiation among a cohort of IDU in Vancouver; describe the prevalence and correlates of MA use among sexual minority drug users; determine whether frequent MA injection predicts emergency department (ED) utilisation; and finally, explore the pathways through which MA use drives injection-related risk behaviour including syringe sharing. Methods: Street-involved youth and IDU participating in three open prospective cohort studies were asked to complete semi-annual interviewer-administered questionnaires, provide blood samples for HIV testing, and consent to hospital database linkages. A variety of longitudinal techniques were used to investigate the association between self-reported MA-related outcomes (e.g., initiation, frequent use) and individual, social, and structural determinants of interest. Results: A systematic review identified consistent associations between MA use and a number of health outcomes, including depression, suicidal ideation, and psychosis. Scientific evidence to suggest an association between MA use and a number of previously suggested harms (e.g., infectious disease transmission, dental problems) is equivocal. Some subpopulations, including sexual minority drug users, are more likely to use MA, which appears to exacerbate exposure to HIV-related risks and other vulnerabilities. Longitudinal analysis revealed that young people, non-injection stimulant users, homeless individuals, and those involved in the city’s open drug scene are most likely to initiate MA injection. The injection of MA, particularly frequently, was associated with a number of health and behavioural outcomes, including an increased hazard of ED utilisation and syringe sharing. Barriers to accessing harm reduction and HIV prevention services likely account for many of these relationships. Conclusions: Methamphetamine use is increasingly common among street youth and IDU in Vancouver. Its use and resultant harms appear to be driven by intersecting individual, social, and structural factors. Comprehensive interventions that are based upon sound scientific evidence and that address existing health and social inequities among marginalised populations are required.

description: Differential categories are now a well-studied abstract setting for differentiation. However not much attention has been given to the process which is inverse to differentiation: integration. This thesis presents an analogous study of integral categories. Integral categories give an abstraction of integration by axiomatizing extra structure on a symmetric monoidal categories with a coalgebra modality using the primary rules of integration. The axioms for integrations include the analogues of integration by parts rule, also called the Rota-Baxter rule, the independence of the order of iterated integrals and that integral of any constant map is linear. We expect consequences of the compatible interaction between integration and differentiation to include the two fundamental theorems of calculus. A differential category with integration which satisfies these two theorem in a suitable sense is what we call a calculus category.
An exploratory study of social aspects of task-based information seeking behavior
Creators: name: Rha, Eun Youp
Publisher: name: No Publisher Supplied
Year: 2020

description: This dissertation aims to explore social aspects of task-based information seeking behavior. It examines how individuals are influenced by their social context when they engage in a task and information seeking for the task. The main theoretical framework of the study is cognitive sociology that recognizes individuals’ mental acts as socially shaped. The study is designed as a qualitative case study using a cross-context comparative approach, which compares cognition and behavior of individuals in different social contexts. Data were collected from twelve individual scholars in two academic disciplines as the type of social contexts: natural sciences and humanities, using either one-on-one interviews or a diary study. A specific task type commonly performed in the two groups was chosen for the inquiry of their task-related cognition and behavior: writing a research proposal to gain external funding for one’s scholarship. The qualitative data were analyzed through the open coding process and compared between the two groups. The findings reveal that the process of individuals’ task-based information seeking is influenced by their disciplines. Specifically, social norms and social practices of the disciplines affected how the individuals perceive a task, attend to information problems of the task, and seek and use information for the task. These findings suggest individuals’ socio-cognitive activities that occur in the process of task-based information seeking: socially constructed understanding of a task and relevance to a task. Based on the findings, a novel model of task-based information seeking behavior was developed, which highlights social factors (social norms, social practices) and socio-cognitive factors (social understanding, social relevance). This exploratory study generates a new idea of cognitive sociological aspects of information seeking behavior by showing the existence of influences of the social context on individuals’ cognitive activities while interacting with a task and information. This new approach to information seeking behavior helps advance understanding of the relationships between information seeking behavior and social contexts. It further contributes to developing information systems for specific sociocultural communities with particular focus on their collective cognitive structures related to information seeking and use.

description: Adsorption is a commonly used technique for removing contaminants from wastewater, such as hexavalent chromium (Cr(VI)) from the wastewater of a chrome plating plant. Chitosan, a prevalent polymeric biomass that is used industrially as a wastewater treatment adsorbent, was crosslinked and functionalized with a low-cost phosphonium salt to enhance its adsorption capacity for Cr(VI). At Cr(VI) concentrations below 130 ppm, the phosphonium-crosslinked chitosan (PCC) adsorbed more than double the amount of Cr(VI) than the unmodified chitosan. The low-cost method for manufacturing PCC may provide a cost-effective alternative to simply increasing the amount of chitosan used in a process. Additionally, PCC was regenerated using magnesium sulfate for repeated use. The recovered Cr(VI) may be recycled back into a chrome plating process.

description: Hot forging is a complex process involving the mutual influence of numerous thermo-mechanical-metallurgical material phenomena. In particular, the strains of transformation-induced plasticity (TRIP) have a significant influence on the distortions and residual stresses of the components. The TRIP strains refer to the anisotropic strains depending on the orientation and significance of the stress conditions during cooling superimposed to the phase transformation. With the use of numerical models, the impact of this effect can be investigated in order to ensure the production of high quality components. However, an experimental determination of the characteristic values of TRIP is challenging, which is why only few corresponding data are available in the literature. Therefore, this paper presents an experimental and numerical methodology as well as the results of studies on the interaction between stresses and phase transformations in the materials AISI 4140 and AISI 52100. The investigations of the TRIP strains are carried out using hollow specimens, which are thermo-mechanically treated in the physical forming simulator Gleeble 3800-GTC. The specimens are austenitised, quenched to test temperature and held there while diffusion controlled phase transformation takes place. The extent of TRIP as a result of different superimposed tensile or compressive loads is determined by means of dilatometry. In addition, the extent of TRIP for diffusionless martensitic phase transformations was investigated by continuous cooling tests under tensile and compressive loads. It was found that the transformation plasticity varies depending on the material, the phase type, the temperature and the tensile or compressive stresses. Subsequently, simulations of the physical experiments using the FE software Simufact. Forming verified the determined phase specific values of TRIP.

Microbially-Enhanced Oil Recovery through Activity of Alkylbenzene-Oxidizing Nitrate-Reducing Bacteria

Subjects: subject: Microbiology
subject: FOS: Biological sciences

description: Heterotrophic nitrate reducing bacteria (hNRB) of the genera Thauera and Pseudomonas can use alkylbenzenes as electron donors for nitrate reduction. The reduction of nitrate by these bacteria increases with the increase in alkylbenzene concentrations of oils especially toluene. The potential of hNRB in microbially enhanced oil recovery (MEOR) was evaluated using sand pack model columns. The concentrations of alkylbenzenes are low in heavy oils. Therefore, water flooded columns were injected with 2-5.6 mM or 1.5 mM of aqueous toluene or ethylbenzene to increase the alkylbenzene content of residual oil in place (ROIP). This was followed by injection of high nitrate (80 mM) to stimulate oil emulsification by hNRB. The hNRB were either cultivated batchwise or in continuous cultures. Injection of sand-packs containing 0.5 pore volumes (PV) of alkylbenzene-amended ROIP with nitrate and a hNRB consortium gave up to 0.10 PV of additional ROIP. Additional oil production was associated with oxidation of alkylbenzenes in the oil phase and reduction of nitrate in the aqueous phase. The dominant microbial species of Thauera and Pseudomonas were isolated from continuous cultures. The isolates were tested for their ability to reduce nitrate with acetate, benzoate, toluene or ethylbenzene as electron donors. Interestingly, only up to 20 mM nitrate was completely reduced to N2 by these isolates with excess toluene or ethylbenzene. Nitrite formed upon reduction of nitrate concentrations of more than 20 mM and was not reduced further to N2. Similar observations were made with the hNRB consortia. Both the isolates had similar MEOR potential either individually or together.

description: In this note we explore the constraints imposed by the existence of equilibrium partition on parity violating charged fluids in 1+1 dimensions at zero derivative order. We write the equilibrium partition function consistent with 1+1 dimensional CPT invariance and which reproduces the correct anomaly in the charge current. The constraints on constitutive relations obtained in this way matches precisely with those obtained using the second law of thermodynamics.
Adult Beginning Learners’ Engagement in Learning Mandarin as An Additional Language at a Canadian Post-secondary Institute

subject: Mandarin as an additional language

subject: curriculum and teaching practice

description: This research investigates the Mandarin learning experience of both heritage and non-heritage beginners in a Canadian post-secondary institution to understand students’ engagement in learning Mandarin as an additional language (MAL). It integrates the complexity theory with an ecological perspective on second language education to capture the dynamic relationship between the learning context and the learners’ engagement in learning MAL. The case study methodology was chosen for the research purpose, and data were collected through classroom observations, focused group conversations and individual interviews. Research findings are presented from two perspectives: the learning experience and the classroom teaching and learning practices. Issues related to student engagement were discussed, including motivation, identity, curriculum, and teaching practice. Analysis on the findings reveals the complexity and ambivalence of Chineseness to heritage and non-heritage MAL learners, which must be understood in their particular socio-cultural context. It also advocates for promoting learner agency through the development of their own “Chinese voice”. In addition, in order to encourage students’ long-term engagement in learning MAL, it is important for the curriculum designers to allocate more time for students to practice Mandarin, make the teaching content more relevant to students’ knowledge and experiences, and develop an assessment system that values learner difference while remaining fair to both heritage and non-heritage students. Implications for MAL education are discussed at the end of the thesis.

The article analyzes the use of elements of Lean production in the Russian Federation and the experience introduction of elements of Lean production in domestic and foreign enterprises. However, there are many theoretical and practical methods for dealing with risks, which can manifest themselves in various production processes, for example, standardization or replacement of obsolete equipment, reduction of production downtime, etc. Today the preference is given to the concept of Lean production. Based on the empirical and theoretical studies, the article gives recommendations on the implementation of Lean production elements in the most “convenient” sectors of the economy in the Khanty-Mansi Autonomous Okrug – Ugra.

description: Cardiac output is an important hemodynamic parameter in critical care and has proven difficult to measure accurately, non-invasively, and without a highly skilled operator. Microwave technologies have been shown to be a possible alternative to current methods for cardiac output determination. However, previously reported microwave systems had limitations including low signal change over the cardiac cycle. In this thesis, we specifically address improving signal change over the cardiac cycle by introducing an ultra-wideband transmission system. We characterize the system using heart models and show that wave propagation through the chest is complex, making the system sensitive to antenna placement. Additionally, a semi-dynamic heart model for characterization of the system in hardware and in simulation is developed. This model shows comparable performance to a complex MRI based heart model. On a human test subject, ultra-wideband readings showed up to 6 dB of magnitude variation over the cardiac cycle.

description: Планирование и осуществление бюджетных расходов в условиях ограниченности финансовых ресурсов, которые государство способно привлечь для выполнения своих целей, задач и функций, требует оценки с точки зрения эффективности этих расходов. Критериями эффективности представляется оправданным признать достижение цели бюджетных расходов, имея в виду повышение уровня жизни населения, рост и развитие отраслей экономики и другие задачи общегосударственного масштаба, качественность целеполагания, позволяющую точно оценить ожидаемую отдачу от профинансированных расходов и подконтрольность бюджетных расходов, которая, в свою очередь, должна характеризоваться эффективностью самого контроля. Обозначенные критерии имеют достаточные основания для применения в юридической теории и практике.

description: Hot-forming tools are subjected to high thermal and mechanical stresses during their application. Therefore, a suitable design of the tool die is important to ensure a long tool life. For this purpose, numerical simulations can be used to calculate the occurring stresses and the temperature development in the tools during the course of a stroke or over several forging cycles. The aim of this research is to investigate the effect of different radii on the resulting stresses in the lower die of the forming tools. Furthermore, the temperature evolution over several cycles is analysed to determine their effect on the temperature. When investigating the stress, it was found that a larger radius leads to a reduction in stresses. In addition, it could be numerically proven that the base temperature of the die levels off after a certain number of cycles. These findings will be used in further research dealing with the service life calculation of dies subjected to thermo-mechanical alternating stresses.
Investigating basketball Twitter: a community examination of serious leisure information practices
Creators: name: Sanchez, Jacob
Publisher: name: No Publisher Supplied
Year: 2020

description: Serious leisure studies in Library and Information Science have focused on the educational and work contexts to the detriment of leisure contexts (Stebbins, 2009). The metatheoretical position to support this view is based in social constructivism (Taljia, Tuominen, & Savolainen, 2005). A synthesis of key claims in serious leisure research is used to create the base knowledge of the serious leisure community. By identifying gaps in the research at the theoretical, topic, contextual, and methodological levels, this following research seeks to address the following research problem: What can we learn about serious leisure in library and information science in the online community of basketball twitter? The proposed dissertation investigates: (1) the serious leisure practices of the basketball twitter community; (2) the positive and negative impacts of the serious leisure information practices in the community; and (3) how, if at all, do these information practices shape the power structure of different groups in the community. Findings are examined in relation to the fields of human information behavior and practices, serious leisure, sport, and social media.
Effective potential for Lifshitz type z=3 gauge theories

description: We consider the one-loop effective potential at zero temperature in field theories with anisotropic space-time scaling, with critical exponent $z=3$, including scalar, fermion and gauge fields. The fermion determinant generates a symmetry breaking term at one loop in the effective potential and a local minimum appears, for non zero scalar field, for every value of the Yukawa coupling. Depending on the relative strength of the coupling constants for the scalar and the gauge field, we find a second symmetry breaking local minimum in the effective potential for a bigger value of the scalar field.

description: Information on the Omega-3 Index (O3I) in the United Kingdom (UK) are scarce. The UK-Biobank (UKBB) contains data on total plasma omega-3 polyunsaturated fatty acids (n3-PUFA%) and DHA% measured by NMR. The aim of our study was to create an equation to estimate the O3I (eO3I) from these data. We first performed an interlaboratory experiment with 250 random blood samples in which the O3I was measured in erythrocytes by gas chromatography, and total n3% and DHA% were measured in plasma by NMR. The best predictor of eO3I included both DHA% and a derived metric, the total n3%-DHA%. Together these explained 65% of the variability (r=0.832, p<0.0001). We then estimated the O3I in 117, 108 UKBB subjects and correlated it with demographic and lifestyle variables in multivariable adjusted models. The mean (SD) eO3I was 5.58% (2.35%) this UKBB cohort. Several predictors were significantly correlated with eO3I (all p<0.0001). In general order of impact and with directionality (- = inverse, + = direct): oily-fish consumption (+), fish oil supplement use (+), female sex (+), older age (+), alcohol use (+), smoking (-), higher waist circumference and BMI (-), lower socioeconomic status and less education (-). Only 20.5% of eO3I variability could be explained by predictors investigated, and oily-fish consumption accounted for 7.0% of that. With the availability of the eO3I in the UKBB cohort we will be in a position to link risk for a variety of diseases with this commonly-used and well-documented marker of n3-PUFA biostatus.

description: This document describes the machine learning models and data fusion techniques included in EIFFEL tools for spatial augmentation of Copernicus datasets and developed during the first 18 months of the project. These tools will be used to provide spatially augmented datasets in the service of EIFFEL pilot CC adaptation and mitigation applications. Five individual spatial augmentation tools will be developed: (i) Sentinel 2 super resolution to increase the spatial resolution of the coarser bands of Sentinel 2 to the resolution of the finer bands. (ii) Thermal Sharpening of Sentinel 3 SLSTR using Sentinel 2 Data. (iii) Spatio-temporal fusion of Sentinel 2 and Sentinel 3 OLCI and SYNERGY data to create data with fine spatial resolution and high temporal resolution. (iv) Sentinel-3 OLCI and SYNERGY data super resolution and (v) fusion of Sentinel 5p data with Sentinel 2, proxy and in-situ data if available.

description: A closer look was taken at a spray binder and the properties of the preforms made with said binder and non-crimp carbon fiber textiles. First the spray process was analyzed, then T-peel and three point flexural tests were carried out to compare the spray binder to other binder systems. While the spray binder showed higher peel strength than most binders found in literature, the measured flexural strength was lower than the values found for powder.
Polarization of synchrotron emission from relativistic reconfinement shocks with ordered magnetic fields

description: We calculate the polarization of synchrotron radiation produced at the relativistic reconfinement shocks, taking into account globally ordered magnetic field components, in particular toroidal and helical fields. In these shocks, toroidal fields produce high parallel polarization (electric vectors parallel to the projected jet axis), while chaotic fields generate moderate perpendicular polarization. Helical fields result in a non-axisymmetric distribution of the total and polarized brightness. For a diverging downstream velocity field, the Stokes parameter U does not vanish and the average polarization is neither strictly parallel nor perpendicular. A distance at which the downstream flow is changing from diverging to converging can be easily identified on polarization maps as the turning point, at which polarization vectors switch, e.g., from clockwise to counterclockwise.

description: Renormalization of composite three-quark operators in dimensional regularization is complicated by the mixing of physical and unphysical (evanescent) operators. This mixing must be taken into account in a consistent subtraction scheme. In this work we propose a particular scheme that allows one to avoid the necessity of additional finite renormalization and is convenient in QCD applications. As an illustration, we calculate the two-loop anomalous dimensions of local three-quark operators in this scheme.
