description: In the petroleum industry, accurately simulating wellbore heat loss through hot fluid injection remains a critical problem as heat transfer and fluid dynamics within the annulus space is complicated. In this study a 2D transient mathematical model is proposed for the conjugate natural convection and radiation within wellbore annuli. The governing equations consist of a vorticity transfer equation, a stream function equation, an energy balance equation and a radiative transfer equation. A finite volume approach with second order upwind scheme is implemented for discretization. Newton-Raphson iteration is deployed for linearization. The algorithm is validated by consistency in simulation results compared with literature. Parameters such as the aspect ratio, radius ratio, radiation and dimensionless time are examined. A case study on vacuum insulated tubing heat transfer using Marlin Well A-6 data showed the merits of the developed program by the consistency of simulation results compared with field measurements.

description: This is the second paper in a series aiming at the analysis of nitrogen abundances in O-type stars, to enable further constraints on the early evolution of massive stars. We investigate the NIV lambda4058 emission line formation, provide nitrogen abundances for a substantial O-star sample in the LMC, and compare our findings with recent predictions from stellar evolutionary models. Stellar and wind parameters are determined by line profile fitting of hydrogen, helium and nitrogen lines, based on synthetic spectra calculated by FASTWIND. We derive nitrogen abundances for 20 O- and 5 B-stars, by analyzing all nitrogen lines present in the available optical spectra. The dominating process responsible for emission at NIV lambda4058 in O-stars is the strong depopulation of the lower level of the transition, which increases as a function of Mdot. Unlike the NIII triplet emission, resonance lines do not play a role for typical mass-loss rates and below. The bulk of our sample O-stars seems to be strongly nitrogen-enriched, and a clear correlation of nitrogen and helium enrichment is found. By comparing the nitrogen abundances as a function of vsini ('Hunter-plot') with tailored evolutionary calculations, we identify a considerable number of highly enriched objects at low rotation. Due to the low initial abundance, the detection of strong Nitrogen enrichment in the bulk of O-stars indicates that efficient mixing takes place already during the very early phases of stellar evolution of LMC O-stars.

description: We report on the evolution of ferromagnetic domain walls during magnetization reversal in elastically coupled ferromagnetic-ferroelectric heterostructures. Using optical polarization microscopy and micromagnetic simulations, we demonstrate that the spin rotation and width of ferromagnetic domain walls can be accurately controlled by the strength of the applied magnetic field if the ferromagnetic walls are pinned onto 90 degrees ferroelectric domain boundaries. Moreover, reversible switching between magnetically charged and uncharged domain walls is initiated by magnetic field rotation. Switching between both wall types reverses the wall chirality and abruptly changes the width of the ferromagnetic domain walls by up to 1000%.

description: This paper aims to set out the role of using aerial remote sensing and marine hazard can play in informing responses to global challenges of coastal cultural heritage and enhancing the sustainable development of coastal zones. Aerial remote sensing and photogrammetric approaches are an integral part of modern archaeological research. In the last two decades of the century, a significant change in approaches to archaeological research has taken place: from direct fieldwork and excavation to remote sensing. In Bulgaria, this scientific discipline is quite new and it is in its infancy. However, during the last few years, the Institute of Oceanology – BAS conducted such types of investigations and a lot of new data have been collected. For this initial survey has been chosen a heritage site on the Bulgarian seashore. The studied area is the archaeological site Caron Limen/Caria at the Cape Shabla and it is determined as highly hazardous to coastal erosion. A systematic archaeological study of the topographic evolution of the coast in association with the functionality of case study area and other coastal facilities during Late Antiquity and Medieval Ages provides new data on the development of coastal life and especially the nature of sea exploitation in the context of maritime commerce.

description: In northern Alberta, mining operations to obtain bitumen from the oil sands generates large volumes of tailings. These are a mixture of sand, clay, water, organic solvents and residual bitumen that are deposited into old open pits, creating tailings ponds, where they are allowed to settle with the final goal of land reclamation. To speed up the sedimentation process, the addition of gypsum (CaSO4 ∙ 2H2O) is currently a management approach used bysome companies. This creates a deep watery mud line with very low oxygen permeability and enough sulfate to support the growth of anaerobic microbial communities. In this thesis work, the microbial physiology and communities associated with oil sands tailings ponds were assessed. Chemical, physiological, and molecular biology approaches were used to determine the key microbial processes (methanogenesis, sulfate reduction/oxidation), identify key substrates, and determine the dominant microbial community members in the anaerobic and aerobic zones of tailings ponds. Microbial community analysis showed that in the anaerobic zone of tailings, the sulfate-reducing/disproportionating bacterium Desulfocapsa. and the sulfide oxidizer/iron reducer Thiobacillus sp. are among the most prevalent organisms when sulfate is present. After sulfate is depleted, methanogenic Archaea become predominantly active and Methanosaeta and Methanolinea in association with Syntrophus dominate in the ponds, presumably interacting to biodegrade the available organic compounds. The residual naphtha components that constitute part of the tailings composition are the preferred electron donors in anaerobic zones (in comparison to naphthenic acids) based on enrichment culture studies. In naphtha-amended laboratory cultures, a variety of methanogens in association with Thauera sp. and Desulfocapsa sp. became enriched as the dominant organisms. Overall, microbial community composition as a function of depth in tailings ponds paralleled key iii microbial processes that were measured (sulfate reduction and methanogenesis). In the aerobic surface water, other microbes with known metabolic capabilities to degrade hydrocarbon-derived compounds such as naphthenic acids were found. The results of this work also showed that operational changes to tailings ponds shift the microbial community structure and functions. For example, pond closure resulted in a shift from a predominantly methanogenic and sulfate-reducing environment to one dominated by putative hydrocarbon degraders, indicating a positive management outcome in microbial activity associated with pond closure.

description: (Abriged) We present analytic models for the formation and evolution of tidal tails and related structures following impulsive disturbances in galaxy collisions. Since the epicyclic approximation is not valid for large radial excursions, we use orbital equations of the form we call p-ellipses. These have been shown to provide accurate representations of orbits in power-law halo potentials. In the case of a purely tidal disturbance the resulting tidal tails have simple structure. Scalings for their maximum lengths and other characteristics as functions of the tidal amplitude and the exponent of the power-law potentials are described. The analytic model shows that azimuthal caustics (orbit crossing zones) are produced generically in these tails at a fixed azimuth relative to the point of closest approach. Long tails, with high order caustics at their base are also produced at larger amplitudes. The analysis is extended to nonlinear disturbances and multiple encounters, which break the symmetries of tidal perturbations. As the strength of the nonlinear terms is varied the structure of the resulting forms varies from symmetric tails to one-armed plumes. Cases with two or more impulse disturbances are also considered as the simplest analytic models distinguishing between prograde and retrograde encounters. A specific mechanism for the formation of tidal dwarf galaxies at the end of tails is suggested as a consequence of resonance effects in prolonged encounters. Qualitative comparisons to Arp Atlas systems suggest that the limiting analytic cases are realized in real systems. We identify a few Arp systems which may have swallowtail caustics, where dissipative gas streams converge and trigger star formation. UV and optical images reveal luminous knots of young stars at these 'hinge clump' locations.

description: The lived experiences of transcultural sexually fluid identities (TSFI) within Canada’s diverse transnational communities remain an unexplored area of individuality and difference. TSFI fits within the general referencing of non-heteronormative sexual identities. In spite of Canada’s projected diversity and accommodating laws for human differences, there is still a stigma attached to non-traditional sexual expressions. Across the diverse Canadian landscape, there are numerous interpretations and understandings of same gender sex (SGS) engagement. In this study, interpretations of TSFI are viewed through a blended theoretical lens of borderland theory (Anzaldúa, 1993) and liminality theory (Turner, 1969). This fused theoretical lens informs a deeper understanding of TSFI and allows for an examination of the many identities that exist within the spectrum of non-heteronormative sexual identities. The non-heteronormative sexual identity context is a fluid spectrum of diversity consisting of various sexual identity labels residing in a space that are referenced in this research as fluidsexuality. Fluidsexuality is a term created for this research and refers to the range of sexual identities present between the binary constructs of heterosexuality and homosexuality. The combined poles of these binary concepts are premised by another term created for this research henceforth referenced as binarysexuality. Within the span of these opposite poles, lies an array of same-gender-sex (SGS) sexually fluid labels. In examining the plethora of emerging SGS labels, this research was guided by autoethnographic methodology through which I explored TSFI identities across Canada. This study investigated the lived experiences of TSFIs and how their lives can inform knowledge development that may result in a rejuvenated adult learning pedagogy focused on diversity and difference.

We present explicit examples of such solutions with special attention paid to thermodynamics of black M-waves (KK-waves), intersecting/interpolating black branes with KK-waves, M2/M5 branes and their descents. We find the conditions on charges and numbers of branes in intersections, under which the dielectric effect of brane polarization becomes manifest on the supergravity side. We also briefly discuss the shear viscosity per entropy bound of M5 and D4 black branes within the AdS/CFT hydrodynamical limit.

Year: 2019

description: Taiwan’s university-level vocational education is faced with a growing need to strengthen students’ soft skills as a means to increase job market eligibility. Students in Taiwan are usually not equipped with group learning skills in junior and senior high school education. These learning skills, however, are an essential component of a successful PBL course, according to past research. This case study describes how a PBL course that adopted various scaffolding strategies helped vocational students improve soft skills associated with real-life issues in the workplace. The adult learners participating in the tailored PBL course were PBL novices, yet their feedback on PBL effectiveness was positive. The success of the PBL course was attributed to 1) the use of effective scaffolding strategies, and 2) learner readiness in the skills needed for group learning.

description: In Primary Care Networks (PCNs) family physicians refer to multidisciplinary teams that provide complimentary services for patients requiring assistance with complex issues or illness. Exercise specialists are a recent addition to these teams, and can support patients through physical activity counselling, education and the appropriate exercise prescription. By utilizing grounded theory methodology and interview techniques, the processes and context of physicians’ considerations of exercise specialists have been explored and summarized within this study. Ten physicians were purposively sampled from Calgary PCNs, and the constant comparative method was applied to code the transcripts and construct analytic categories to saturation. The core category states that although physicians are receptive to a professional who promotes physical activity and wellness to their patients, exercise specialists are currently “hidden” from PCN family physicians in Calgary. This core category is supported by three subcategories: Exercise Specialist Factors, Access, and Relationships.

Our primary aim is to develop efficient methods to compute perturbative corrections to correlation functions. This analysis also allows us to examine potential subtleties which may arise when calculating off-shell quantities in light-cone gauge. We comment on the intriguing possibility that the manifest N=4 supersymmetry in this approach may allow for a compact description of entire multiplets and their correlation functions.

description: Nonostante la Imagem da vida cristã del frate gerolamino Heitor Pinto sia stata una delle opere più celebri della letteratura portoghese del XVI, sono ancora molte le questioni irrisolte riguardo al testo, in particolare per ciò che concerne la cronologia e il luogo di pubblicazione delle innumerevoli traduzioni castigliane. Oltre a fare luce sulla questione, questo contributo prende in esame la traduzione castigliana manoscritta della Imagem da vida cristã di Frey Heitor Pinto, conservata nella biblioteca dell’Escorial di Madrid, sulla quale attualmente non esiste alcuno studio critico, se non le poche osservazioni di Ricard (1972). In particolare, verrà analizzato il prologo del traduttore, assente in tutte le altre edizioni a stampa. Although the Imagem da vida cristã by the Hieronymite friar Heitor Pinto was one of the most famous works of Portuguese literature of the 16th century, there are still many unresolved questions regarding the text, particularly concerning the chronology and place of publication of the countless Castilian translations. In addition to shedding light on the issue, this contribution examines the Castilian manuscript translation of Frey Heitor Pinto's Imagem da vida cristã, preserved in the Escorial Library in Madrid, on which no critical study currently exists, apart from Ricard's (1972) few observations. In particular, the translator's prologue, absent in all other printed editions, will be analyzed.

description: The origin and delineation of organizational identity (OI) as a construct has been well studied and documented by researchers. This research has suggested that insufficient study has been conducted on how organizational identity formation takes place from organizational inception, which factors influence this formation (Gioia, Price, Hamilton, & Thomas, 2010), and that there is a limited understanding of how organizational identity forms. More specifically, there is limited knowledge of how organizational members perceptions of leadership, and of professional identity, impact organizational identity formation. This descriptive, single case study grounded in the interpretive qualitative paradigm and featuring a sample of thirty-five organizational members of a virtual education organization, examines organizational identity formation in a virtual education organization, and advances rich data regarding such an organization’s identity formation. Data were collected using interviews and through the examination of organizational documents. Analysis of the data used case study procedures and the constant comparative method borrowed from grounded theory. Findings indicated that organizational identity formation is impacted by the members’ perceptions of formal and informal leaders and their leadership style, but that organizational identity resides in an amalgam of referents that are difficult to isolate as a function of a single impactful influence such as organizational leaders/leadership The perceived ability to establish a professional identity also influenced organizational identity formation. Organizational complexity negatively impacted the members’ abilities to develop professional identities, and influenced their perceptions of the organization’s culture and influenced the organizational identity formation.

description: Anxiety is a common presenting concern for individuals at clinical high risk (CHR) for psychosis and one treatment that may be effective for anxiety is heart rate variability (HRV) biofeedback. The aim of this study was to test the efficacy of HRV biofeedback in reducing anxiety and distress in those at CHR. Twenty participants who met minimum scores for anxiety and distress completed four weeks of a HRV biofeedback intervention and received pre and post intervention assessments. There was a significant decrease in presentation of dysphoric mood and impaired ability to tolerate normal stressors. There was no change on self-report measures of anxiety and distress. Feedback and adherence were generally good. HRV biofeedback may be a feasible treatment option for individuals at CHR who have concerns with impaired stress tolerance and dysphoric mood. Future studies with a randomized controlled trial design will be necessary to further determine efficacy.
Hot subdwarf stars in close-up view - II. Rotational properties of single and wide binary subdwarf B stars

description: Subluminous B stars (sdBs) form the extremely hot end of the horizontal branch and are therefore related to the blue horizontal branch (BHB) stars. While the rotational properties of BHB stars have been investigated extensively, studies of sdB stars have concentrated on close binaries that are influenced by tidal interactions between their components. Here we present a study of 105 sdB stars, which are either single stars or in wide binaries where tidal effects become negligible. The projected rotational velocities have been determined by measuring the broadening of metal lines using high-resolution optical spectra. All stars in our sample are slow rotators (${v_{\rm rot}\sin{i}}<10\,{\rm km\,s^{-1}}$). Furthermore, the $v_{\rm rot}\sin{i}$-distributions of single sdBs are similar to those of hot subdwarfs in wide binaries with main-sequence companions as well as close binary systems with unseen companions and periods exceeding $\simeq1.2\,{\rm d}$. We show that blue horizontal and extreme horizontal branch stars are also related in terms of surface rotation and angular momentum. Hot blue horizontal branch stars ($T_{\rm eff}>11\,500\,{\rm K}$) with diffusion-dominated atmospheres are slow rotators like the hot subdwarf stars located on the extreme horizontal branch, which lost more envelope and therefore angular momentum in the red-giant phase. The uniform rotation distributions of single and wide binary sdBs pose a challenge to our understanding of hot subdwarf formation. Especially the high fraction of helium white dwarf mergers predicted by theory seems to be inconsistent with the results presented here.

description: Albert Einstein's real "biggest blunder" was not the 1917 introduction into his gravitational field equations of a cosmological constant term Λ, rather was his failure in 1916 to distinguish between the entirely different concepts of active gravitational mass and passive gravitational mass. Had he made the distinction, and followed David Hilbert's lead in deriving field equations from a variational principle, he might have discovered a true (not a cut and paste) Einstein-Rosen bridge and a cosmological model that would have allowed him to predict, long before such phenomena were imagined by others, inflation, a big bounce (not a big bang), an accelerating expansion of the universe, dark matter, and the existence of cosmic voids, walls, filaments, and nodes.

description: Increased maternal fetal attachment (MFA) is associated to improved health practices. A tool to measure MFA within an Arab cultural context was developed to help health care providers identify and help women with low MFA. Muller’s 21-item Prenatal Attachment Inventory (PAI) was translated from English into Arabic and tested on 250 pregnant Arab women in Riyadh, Saudi Arabia to measure its psychometric properties and appropriateness within an Arab cultural context. A cross-sectional quantitative study was conducted in two phases. First, the tool was translated using the Universal Translation Approach and assessed for content validity. In this phase there were four new items added to the original tool and their validity was tested in the second phase. In the second phase, the tool was tested on the study population, descriptive statistics were developed, association tests were used to explore associations between demographic variables and MFA, factor analysis was conducted and reliability was assessed using Cronbach’s alpha coefficient. Associations between MFA and maternal variables were found such as downloading an application to follow the baby’s growth, planning to breastfeed the baby and parity. The Arabic tool could serve Arab-speaking countries and help researchers explore new associations between MFA and the social determinants of health for Arab mothers and babies.

It shows that the starting materials have an obvious effect on the impurity phases in final superconducting tapes. Compared with the other samples, the samples fabricated by SmAs, FeO, Fe2As, and SmF3 have the smallest arsenide impurity phase and voids. As a result, these samples possess much denser structure and better grain connectivity. Moreover, among the three kinds of samples fabricated in this work, this kind of sample has the highest zero-resistivity temperature ~40 K and largest critical current density ~4600 A/cm^2 in self-field at 4.2 K. This is the highest Jc values reported so far for SmFeAsO1-xFx wires and tapes.

Quantifying the Limitations of using Time Domain Airborne Electromagnetic Methods for Characterizing Heterogeneity in the Edmonton-Calgary Corridor

description: As part of a regional groundwater mapping project the Alberta Geologic Survey commissioned a time domain airborne electromagnetic survey of the Edmonton-Calgary Corridor. To analyze the suitability of data for groundwater mapping, research was carried out on a subset of the data. An analysis of geophysical logs from twelve boreholes indicates clay has a higher conductivity than sand, but the relationship is non-unique so supplementary data may be required for interpretation. An analysis of TEM data uncertainty shows measurements can be imprecise because they are affected by non-geologic noise, but it is possible to use secondary sources of data, such as resistivity logs, to recalibrate TEM measurements and improve accuracy. Finally, benefits and limitations of TEM inversion were examined, suggesting TEM can only resolve large scale changes in conductivity structure. As a result it is not an appropriate tool for mapping small scale changes in conductivity associated with groundwater mapping.

description: Magnetization reversal using circularly polarized light provides a new way to control magnetization without any external magnetic field and has the potential to revolutionize magnetic data storage. However, in order to reach ultra-high density data storage, high anisotropy media providing thermal stability are needed. Here, we evidence all-optical magnetization switching for different TbxCo1-x ferrimagnetic alloy composition and demonstrate all-optical switching for films with anisotropy fields reaching 6 T corresponding to anisotropy constants of 3x106 ergs/cm3. Optical magnetization switching is observed only for alloys which compensation temperature can be reached through sample heating.
Perceptions of Risk and Coping Mechanisms Among Victims of Domestic Violence

description: Given evolving technological advances, GPS technology has increasingly been applied to domestic violence situations. In Central Alberta, a project was undertaken to equip high-risk domestic violence offenders with GPS tracking technologies. In addition to this, a GPS tracking device, equipped with an alert button, has also been made available to victims of domestic violence. This study examined perceptions of risk and coping mechanisms among victims of domestic violence, with a specific focus on GPS technology and the nature of victim protection in the context of technologies proposed to increase perceptions of safety in circumstances of domestic violence. Overall, the study found that the devices did not appear to create a false sense of security, but were rather seen as another tool the women were able to use in order to manage their risk of abuse.
The role of the protein tyrosine phosphatase PRL-3 in regulating cell signaling in cancerous and non-cancerous cell lines
Creators: name: Bessette, Darrell Christopher

description: Protein tyrosine phosphorylation is an important mechanism that regulates complex intracellular signaling pathways that determine many cellular activities, such as proliferation, growth, and differentiation. Phosphorylation is regulated by the concerted activities of protein tyrosine kinases and protein tyrosine phosphatases (PTPs), which respectively add and remove phosphate to and from proteins. PRL-3 is a member of a novel subfamily of PTPs that possess prenylation motifs at the C-terminus, thus effecting membrane targeting of these proteins. High PRL-3 expression is an indicator of disease progression and poor prognosis in a number of carcinomas. While some of the biology of PRL-3 has been determined, the molecular mechanisms by which PRL-3 can impart enhanced malignancy to cells and tumours, and the means by which it is upregulated in these cancers are not well understood. I established three independent cell systems to investigate the role of PRL-3 in signaling: an inducible system expressing wild-type and catalytically-inactive Flag-tagged PRL-3 in HEK 293 (293) cells, a constitutive system expressing EGFP-tagged wild-type, catalytically-inactive and prenylation-deficient PRL-3 in LNCaP prostate carcinoma cells, and a shRNA-mediated stable knockdown of PRL-3 in LNCaP, C4-2 and DU-145 prostate carcinoma cells. I examined the effect of altering PRL-3 expression in these cell systems upon phenotypic characteristics of proliferation, migration, and invasion, and on modulating the expression or activation of a number of signaling molecules. PRL-3 was found to promote invasion and/or migration of 293 and prostate carcinoma cells. PRL-3 limited the proliferation of LNCaP cells, but had no effect on the proliferation of the other cell types. PRL-3 expression reduced E-cadherin expression in 293 cells but did not alter this or other EMT marker expression in prostate cancer cells. While PRL-3 expression had little effect on cell signaling in untreated 293 or prostate cancer cells, iii overexpression of PRL-3 in growth factor-stimulated 293 cells regulated Mek-dependent Erk activity. PRL-3 localized at the plasma membrane with adherens junction proteins but did not alter E-cadherin, β- catenin or α-catenin expression or interactions. These studies support the findings that PRL-3 imparts metastasis-associated properties upon different cell types but the molecular mechanisms behind this behaviour remain unresolved.
Predicting the Risk of Intracerebral Haemorrhage in Patients with Acute Ischemic Stroke Receiving IV-alteplase with or Without Endovascular Thrombectomy

description: Intracerebral Haemorrhage (ICH) is a devastating complication of acute ischemic stroke (AIS) treatment with no known effective management protocols. The need to identify patients at risk of developing this condition is becoming increasingly recognized among the stroke community. Computed tomography perfusion (CTP) is a powerful diagnostic imaging tool that measures blood flow in the brain. This tool can also be used to provide information regarding the integrity of the blood-brain barrier (BBB). Severe brain ischemia and consequent disruption of the BBB are probable mechanisms for why ICH occurs after AIS treatment. The goal of my research is to investigate the potential role of CTP primarily and other imaging and clinical parameters in predicting ICH secondary to AIS treatment in patients.

Focus+Context via Snaking Paths

description: Focus+context visualizations reveal specific structures in high detail while effectively depicting its surroundings, often relying on transitions between the two areas to provide context. We present an approach to generate focus+context visualizations depicting cylindrical structures along snaking paths that enables the structures themselves to become the transitions and focal areas, simultaneously. A method to automatically create a snaking path through space by applying a path finding algorithm is presented. A 3D curve is created based on the 2D snaking path. We describe a process to deform cylindrical structures in segmented volumetric models to match the curve and provide preliminary geometric models as templates for artists to build upon. Structures are discovered using our constrained volumetric sculpting method that enables removal of occluding material while leaving them intact. We find the resulting visualizations effectively mimic a set of motivating illustrations and discuss some limitations of the automatic approach.

description: We study the decay K^+ -> pi^+ pi^0 e^+ e^-, currently under analysis by the NA62 Collaboration at CERN. In particular, we provide a detailed analysis of the Dalitz plot for the long-distance, gamma^*-mediated, contributions (Bremsstrahlung, direct emission and its interference). We also examine a set of asymmetries to isolate genuine short-distance effects. While we show that charge asymmetries are not required to test short distances, they provide the best environment for its detection. This constitutes by itself a strong motivation for NA62 to study K^- decays in the future. We therefore provide a detailed study of different charge asymmetries and the corresponding estimated signals. Whenever possible, we make contact with the related processes K^+ -> pi^+ pi^0 gamma and K_L -> pi^+ pi^- e^+ e^- and discuss the advantages of K^+ -> pi^+ pi^0 e^+ e^- over them.
