Stability and chemistry of boron containing cations, anions, and neutrals
Creators: name: Walrond, Lisa
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Chemistry, General.

description: The structure, thermochemistry, isomerization and dissociation of the CH2BH2 and CH3BH radicals, cations and anions have been explored with a wide range of ab initio levels of computational theory and their formation has been probed by tandem mass spectrometry and RRKM kinetic theory. Calculations predict that CH2B H2&ceilr0;+ is not an equilibrium structure on the potential energy surface. The CH3B H&ceilr0;+ was characterized by its collision-induced dissociation mass spectrum and neutralization-reionization (NR) mass spectrometry was used to generate the CH3B H&ceilr0;• radical. While both CH2B H2&ceilr0;• and CH3B H&ceilr0;• are stable with respect to isomerization and dissociation, a relatively low barrier to the 1,2-hydrogen shift means that pure CH3B H&ceilr0;• can only be made cold, and so the above NR experiment likely produces a mixture of neutrals, of which only CH3B H&ceilr0;• can be reionized. Vertical electron attachment to CH3B H&ceilr0;• is endothermic which means the CH3B H&ceilr0;- anion is unlikely to be made from the cation or radical. In addition, the anion lies in a shallow well of only 48 kJ mol-1 and will undergo fast isomerization to CH2B H2&ceilr0;- below the dissociation limit. The B(N(CH3)2)3 radical cation and dication structures and dissociation products have been investigated by high level ab initio calculations and experimentally characterized by tandem mass spectrometry. The KER was measured for the metastable dissociation products of the B(N(CH 3)2)3 dication. There were four observed dissociation channels, two involving neutral losses and two involving charge separations. The neutral loss channels successfully compete with the charge separations, the dominant process actually being neutral loss of H2. The KER for the four metastable dissociations were determined to be T0.5(141++) = 368 +/- 18 meV, T0.5(127++) = 144 +/- 12 meV, Th (99+) = 2365 +/- 156 meV, Th(44+) = 2046 +/- 279 meV, and Th(128+) = 1942 +/- 332 meV.
Swarm intelligence-based image segmentation

Subjects: subject: Computer Science.

description: One of the major difficulties met in image segmentation lies in the varying degrees of homogeneousness of the different regions in a given image. Hence, it is more efficient to adopt adaptive threshold type methodologies to identify the regions in the images. Throughout the last decade, many image processing tools and techniques have emerged based on the former technology which we called conventional and new technologies such as intelligent-based image processing techniques and algorithm. In some cases, a combination of both technologies is adapted to form a hybrid image processing technique. Intelligent-based techniques are increasing nowadays. Due to the rapid growth of agent-based technology's environments which are adopting numerous agent-based applications, tools, models and softwares to enhance and improve the quality of the agent based approach. In case of intelligent techniques to doing image processing; swarm intelligence techniques rarely have been used in term of image segmentation or boundary detection. However, there are many factors that make this task challenging. These factors include not only the limited such increasing number of agents in the environment, and the presence of techniques., but also how to efficiently find the right threshold in the image, develop a flexible design, and fully autonomous system that support different platform. A flexible architecture and tools need to be defined that overcomes these problems and permits a smooth and valuable image processing based on these new techniques in image processing. It would satisfy the needs of end users. This thesis illustrates the theoretical background, design, swarm based intelligent techniques and implementation of a fully agent-based model system that is called SIBIS (Swarm Intelligent Based Image Segmentation).

Dropping out and in: Returning to high school in rural Canada
Creators: name: George, Anne L
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Education, Adult and Continuing.
subject: Education, Secondary.

description: This qualitative study explored the personal and educational experiences of five adult education students who returned to high school in rural Ontario. Examining the voices of the rural adult education students led to a greater understanding of the meaning of dropping out and returning to high school. A framework for the participants' journey is presented using a lifecourse trajectory perspective. The findings and implications of this study suggest that rural adult students face unique challenges, and that a dialogue around existing policy and practices might strengthen the program even further.
"Ce lexique sied-il à Dieu"? Analyse diachronique des usages du verbe seoir
Creators: name: Clark, G. Aileen
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2003
Subjects: subject: Language, Linguistics.

description: En France, lorsqu'on parle d'un comportement qui sied, on sous-entend un comportement social qui se définit en fonction de l'idéologie qui gouverne la société. Le verbe seoir constitue alors le noeud sémantique du champ lexical de la conduite sociale en France. Le but de cette thèse est d'étudier l'évolution des usages du verbe seoir, du XII e au XXe siècle, la principale hypothèse étant que l'usage du verbe dans les textes littéraires reflète les différents comportements valorisés par la société. La méthode d'analyse consiste a relever les éléments syntaxiques et sémantiques qui paraissent avec seoir pour ensuite etudier comment ces éléments changent au cours des siècles. Cette étude est composée de deux parties, d'une bibliographie limitée aux ouvrages et articles cités dans la recherche. Les occurrences supplémentaires qui suivent le même modèle que celles qui sont traitées dans l'analyse se trouvent en annexe. La première partie, intitulée "Critique et Méthodologie," comprend six chapitres. Après une introduction a la thèse, le chapitre un délimite le champ lexical et les concepts théoriques qui s'y rapportent. Le deuxième chapitre offre un aperçu lexicologique sur seoir. Dans le chapitre trois, nous discutons du rapport intime entre la langue, la littérature et la société. Le quatrième chapitre traite de la méthode linguistique utilisée pour faire l'analyse de seoir. Le chapitre cinq presente les différentes bases de données informatisées (ARTFL et TFA) qui constituent le corpus d'étude ainsi que les outils informatisés qui facilitent le travail de recherche (TACT et FileMaker). La deuxième partie constitue l'analyse des usages du verbe seoir. Après une introduction à l'analyse (chapitre 6), les chapitres traitent de l'analyse de seoir par période de temps: Moyen Age (chapitre 7), XVIe siècle (chapitre 8), XVIIe siècle (chapitre 9), XVIII e siècle (chapitre 10), XIXe siècle (chapitre 11), XXe siècle (chapitre 12). La conclusion propose un résumé de l'analyse. Cette étude montre que l'usage de seoir reflète effectivement différentes tendances sociales au cours des siècles: la désacralisation de la société francaise, l'élargissement de l'élite sociale, l'ascension de la bourgeoisie, le phénomène de l'agisme et la théâtralité de l'individu. Ce travail montre également que le verbe seoir est de moins en moins employé au XXe siècle parce qu'il reflète la tendance vers la démocratisation sociale en France.
Investigation of the yttria stabilized zirconia (100) surface by X-ray photoelectron spectroscopy and scanning probe microscopy: Development of a model catalyst support

description: Techniques and methodologies developed to reproducibly prepare and characterize yttria stabilized zirconia (YSZ) for use as a model catalyst support are presented. Analysis of a large number of YSZ(100) single crystals are examined by ambient atomic force microscopy (AFM), and x-ray photoelectron spectroscopy (XPS), in order to understand sources of variability and irreproducibility in the YSZ literature. The knowledge gained by ambient studies is then utilized to guide development of instrumentation and techniques to characterize YSZ under ultrahigh vacuum, and to prepare the (100) surface for self-consistent model catalyst studies. In ambient conditions the complex interaction of impurities and defects are demonstrated to produce an inhomogeneous defect layer composed of stoichiometric and oxygen deficient regions. Introduction of oxygen vacancies modifies the lattice constant of YSZ, causing it to dewet and self organize at high temperature. Furthermore, stoichiometric and defective surface regions are shown to interact with metal deposited through e-beam evaporation in vastly different manners. Therefore variation in the defect layer can produce large dispersion in deposited metal location and dimension. In-situ UHV scanning tunneling microscopy (STM) is used for the first time to study the surface of a bulk YSZ single crystal, images are presented in combination with XPS results. These techniques are used to characterize surface impurities and their interaction with YSZ. Cationic impurities are shown to accumulate at the upper surface region, but can be removed by heating to approximately 450°C, whereas silicon requires heating to at least 900°C. Carbon is found to react with YSZ(100) in complicated ways. Initial defect structure, in the form of oxygen vacancies and solubilized/surface carbon, can provide the conditions at elevated temperature to allow the reduction of zirconia to zirconium carbide. This carbide may be removed, along with the specific defect structure that provides the pathway for carbide formation, through thermal oxidation. STM shows that the clean and stoichiometric YSZ(100) surface may reconstruct under tip induced or thermally reductive conditions to form large clusters. With the removal of kinetic hindrance through heat, the clusters can self organize in a manner similar to that observed in ambient conditions.

Missing the Link: A Gendered Perspective on Labour Regulation in Global Value Chains
Creators: name: Stewart, Ann
Publisher: name: feminists@law
Year: 2013

description: This paper argues that feminist scholarship has a aluable contribution to make to GVC analysis. It builds on the approach develoepd in my recent monograph, Gender, Law and Justice in a Global Market (Cambridge UP, 2011), to consider the way in which contextually specific 'gender contracts' relating to responsibilities for work and care contribute to the way in which women engage with labour markets. Women's association with the socially reproductive sphere contributes to the risks they face as well as the flexibility they embody. Feminist critiques of labour law which address the way in which it constructs boundaries between unvalued, unregulated social reproductive activiteis and employment have particular resonance for GVC analysis with its concern to trace the way in which each stage in the process of production (including formal and informal working) contributes to the distribution of value and the creation of risk for workers. These critiques have also revealed the gendered consequences of the commercialisation of labour relationships associated with the provision of services particularly in relation to body work and the challenges these developments pose for the conceptual basis for labour law. However the paper extends its analysis to address the generalised private standard setting which has emerged as governance at firm level and the macroeconomic regulatory contexts that contribute to the distribution of value within the chains. The international women's rights movement in conjunction with labour activists have developed a framework for implementation of increasingly substantive rights for women. If national economic policies are increasingly dominated by global and regional trade regimes on the one hand and governance through private standards on the other, what happens to any wider state-based gender strategy? Is there transference of 'rights' discourse from the state and incorporation into the market governance of trade and private standard setting? The paper therefore argues that bringing gender into the social context is essential.

Modern Workplaces and Modern Families: Revising the Work-Family Concept
Creators: name: Weldon-Johns, Michelle
Publisher: name: feminists@law
Year: 2013

description: The recent government response to the Consultation on Modern Workplaces proposes revisions to the current administration and concept of parental leave alongside extending the right to request flexible working to other employees. These proposals in many ways reflect the package of rights available in Sweden. While the experience in Sweden suggests that this may encourage greater utilisation of parental leave, and in particular, increase fathers' uptake of such rights, it is unlikely to fundamentally challenge their underpinning gendered nature. In this paper it is argued that instead of focusing on re-branding the current package of rights, the legislation should instead re-envision the concept of the family. The traditional male breadwinner and dual breadwinner families have been the typical focus of these rights, so this approach will be critically contrasted with a focus on a wider understanding of the family encompassing intergenerational, multi-household and other atypical family care models. It is argued that such an approach may offer a more appropriate understanding of the work-family conflict which better addresses the cmpeting needs of working carers and atypical family forms.

Passing the Buck: Unpaid Care, Precarious Work and the Children and Families Bill 2013
Creators: name: Grabham, Emily
Publisher: name: feminists@law
Year: 2013

description: My current research focuses on gaps in UK law which exclude women in precarious work from using work-life balance mechanisms. UK government policy-makers currently use two key strategies to address women's care commitments and participation in the paid labour market. First, recent New Labour and Coalition governments have promoted flexible work as a means of managing unpaid care commitments alongside paid employment. Yet flexibility often produces precarious work conditions and does very little to resolve underlying gender inequalities in the quality, remuneration, and longevity of women's paid work. Second, women and other carers have been provided with employment equality rights, for example to request flexible work, with the aim of changing working environments to accommodate a wider range of working patterns. Yet, these rights consistently benefit women in relatively permanent, professional jobs and for legal and other reasons, exclude the workers who need them most: precarious workers, whose status within the workplace is often low and whose ability to negotiate work around care is compromised. This is even more of a problem for those entering the labour market as a result of conditionality requirements in new welfare legislation. I am working on a three-year, ESRC-funded project, which combines doctrinal analysis of UK labour and equality law with empirical socio-legal research on the experiences of female precarious workers in managing work and care. In this paper, I outline preliminary findings from the research, focusing in particular on legal gaps in work-life balance provision, with the hope of analysing those gaps in context once empirical research is complete. My aim overall is to asess how work-life balance measures operate (or not) for those who need them the most.

Are Research Data a 'Common' Resource?
Creators: name: Mauthner, Natasha
Publisher: name: feminists@law
Year: 2012

description: This article explores the implicit philosophical framework that underpins, and provides the moral and political justification for, the move towards treating data as a so-called common resource. It begins by tracing the emergence of the idea of viewing data as an open access common resource. It then outlines the regulatory, policy and legislative mechanisms that have been instituted to encourage and ensure that researchers comply with data sharing requirements, and that are institutionalising new ownership regimes away from research data being treated de facto as private property towards it becoming public property. It also spells out the case being made for treating data as a public good, including scientific, moral, economic and political arguments. The article then moves on to suggest that positioning data as a common resource is dependent on a Cartesian and representational understanding of data, their production, and their use in the making of knowledge, drawing in particular on the work of Karen Barad. Barad’s critique of classical Cartesian and Newtonian metaphysical assumptions helps to reveal the positionality of the assumed universalism of treating research data as a given and a priori common resource. The final section of the article considers what treating data as a common resource and public good, and the exclusion of the labour and relations of data producers that it depends on, does ontologically, epistemologically, morally and politically. In particular, it suggests that emerging regulatory, policy, legislative and discursive practices reinforce, institutionalise and legitimise power differentials and inequalities precisely along the lines that feminist scholars have been contesting for over four decades.

Women Workers: Is Equality Enough?
Creators: name: Fudge, Judy
Publisher: name: feminists@law
Year: 2012

description: This is the text of an Open Lecture delivered by Professor Judy Fudge at the University of Kent on 16 January 2013. By focusing on the patterns of change and continuity in women’s work the lecture traces the profound transformations in national and transnational labour markets that have been driven by global capitalism, while questioning the normative goal of women’s claims for equality in employment. The lecture aims to historicize the narrative of the expansion of the legal definition of equality and women’s employment – to recontexutalise and re-interpret this progressive narrative in light of changes in the labour market and political discourse. Women’s claims to equality in employment have become more nuanced and complex as the contours of the gender order have been redrawn to reflect the growing diversity between women and a deterioration in what has been the normative or standard employment relationship for men. Using Canada and the United Kingdom to illustrate the changes in the labour market and gender order, the lecture calls into question the potential of equality norms, however expansive, to solve the problems women workers face in the wake of global austerity.

In Defence of Experience
Creators: name: Oksala, Johanna
Publisher: name: feminists@law
Year: 2012

description: This paper studies our philosophical understanding of experience in order to question the current political and theoretical dismissal of women's experiential accounts in feminist theory. The focus is on Joan Scott's critique of experience, but the philosophical issues motivating the discussion go beyond Scott's work and concern the future of feminist theory and politics more generally. I ask what it means for feminist theory to redefine experience as a linguistic event the way Scott suggests. I attempt to demonstrate that the consequences that she draws form such a theoretical move are both philosophically and politically problematic. A critical study of the evidence of experience does not have to imply metaphysical or epistemological foundationalism as Scott claims, but on the contrary, such a study is indispensable for challenging them. It is my contention we must hold on to experience as an important resource for contesting sexist discourses and oppressive conceptual schemas.

Values Beyond Value? Is Anything Safe from being Subsumed by the Logic of Capitalism?
Creators: name: Skeggs, Beverley
Publisher: name: feminists@law
Year: 2013

description: There has been a great deal of interest recently in how capital has intervened in almost every area of life, leading some to propose new forms of capital eg ‘emotional capitalism’ (Illouz), and others to suggest that processes of valuation are now the major method for understanding the social world (Arviddson, Adkins and Lury). Whilst, no doubt, capital behaves according to its own logic, finding new lines of flight, converting affects such as sentiment and suffering into value, making multi-culturalism marketable, generating new forms of bio-capital, and making many of our actions subject to the logic of calculation (our writing for instance), I want to explore what is left behind. If we only understand the world from the perspective of the logic of capital does anything remain? I’ve been caught in Bourdieu’s paradox for some time. Is it possible to escape? Are there any values beyond valuation?

description: Nonreciprocity, arising from the breaking of time-reversal symmetry, has become a fundamental tool in diverse quantum technology applications. It enables directional flow of signals and efficient noise suppression, constituting a key element in the architecture of current quantum information and computing systems. Here we explore its potential in optimizing the charging dynamics of a quantum battery. By introducing nonreciprocity through reservoir engineering during the charging process, we induce a directed energy flow from the quantum charger to the battery, resulting in a substantial increase in energy accumulation. Despite local dissipation, the nonreciprocal approach demonstrates a fourfold increase in battery energy compared to conventional charger-battery systems. We demonstrate that employing a shared reservoir can establish an optimal condition where nonreciprocity enhances charging efficiency and elevates energy storage in the battery. This effect is observed in the stationary limit and remains applicable even in overdamped coupling regimes, eliminating the need for precise temporal control over evolution parameters. Our result can be extended to a chiral network of quantum nodes, serving as a multi-cell quantum battery system to enhance storage capacity. The proposed approach is straightforward to implement using current state-of-the-art quantum circuits, both in photonics and superconducting quantum systems. In a broader context, the concept of nonreciprocal charging has significant implications for sensing, energy capture, and storage technologies or studying quantum thermodynamics.

A new approach to the Rough Set multicriteria optimisation method
Creators: name: Vafaeyan, Shadi
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Engineering, Chemical.

description: In the recent years, enormous amount of attention has been given to multicriteria optimisation problems. These are problems with conflicting objectives, to which it is impossible to obtain an optimum solution that contains the best value for every criterion simultaneously, therefore the decision maker must decide on a reasonable compromise. There have been numerous developments of optimisation methods to aid the decision-maker in addressing such problems. These methods can be divided to two categories based on the use or not of the Pareto domain (PD). The Pareto domain is the set of all non-dominated solutions to the multicriteria problem, where no solution is better or worse than any other in the set when all the criteria are considered equal in importance. This thesis is a collection of two papers that focuses on a new approach to the Rough Set multicriteria optimisation technique. Rough Set method (RSM) requires the determination of the PD as the first step to the optimisation process. In the suggested new approach to RSM, a more systematic way in the selection of points from the PD, that is given to the expert for ranking and then the generation of rules by which the entire PD is ranked, is presented. The RSM that operates based on this new approach was applied to three case studies in paper 1 and to "Beer quality optimisation" in the second paper. The results were compared to the ones obtained by the traditional RSM, Net Flow method and the simple Least Squares method. In conclusion, the new RSM showed to be the most reliable and robust method of all.

description: Current scholarship on migrant sex work warns us to avoid viewing female migrant sex workers as either passive "victims" of male dominated trafficking schemes or ruthless villains who chose prostitution and illegal migration. This thesis concentrates on the print media in two democratic states, Canada and the United Kingdom in order to investigate how the public is being educated on migrant sex work. Specifically, this thesis analyzes representations of female migrant sex workers in news articles published by the British newspaper The Guardian, and the Canadian newspaper The Globe and Mail . A total of 100 articles are selected by keyword search from the years 2000-2008. They are analyzed by using frame analysis. Overall, this thesis concludes that the audiences of The Globe and Mail and The Guardian are provided with a partial account of who migrant sex workers are and how or why they end up in the sex trade.
Performance Evaluation and Comparison of Routing Protocols in Wireless Sensor Network with Mobile Sinks

Year: 2010
Subjects: subject: Engineering, Electronics and Electrical.

description: Wireless Sensor Networks (WSNs) usually consist of a large number of sensors which have the ability to detect events, generate reports and transmit them to the sink which collects the data reports. The mobile sink has been adopted to improve network performance of WSNs. It is necessary to inform sensors of a topological or location change of a moving sink, however frequent location updates from mobile sinks can lead to high energy consumption of sensors, and therefore shorten the network lifetime. Many protocols have been proposed in the past few years trying to achieve the energy efficiency goal in WSNs with mobile sinks. This thesis investigates six protocols: TTDD, Locator, LURP, Efficient Routing, TwinRoute and Dual-Sink. First, they are implemented in ns-2, then extensive performance evaluations are conducted. Furthermore, the experimental results are compared and analyzed. This thesis reveals both the advantages and performance issues of these protocols, and it provides the basis for future research.

Subjects: subject: Engineering, Electronics and Electrical.

description: There are over 40,000 strokes in Canada each year, with a 75% rate of physical impairment. Virtual Rehabilitation was proposed as an alternative for recovering stroke patients, since conventional rehabilitative methods limit patients with time constraints. Our research presents a virtual rehabilitation system, consisting of a series of applications and using the Immersion CyberForceRTM system. The system is designed to improve patients' abilities to perform everyday tasks, such as drinking tea, as per the feedback of occupational therapists. It also includes an interface for occupational therapists to configure each exercise. We designed a progress measurement component for automated advancements without requiring an occupational therapist to analyze performance results. An LSR Analyzer normalizes the raw sensor values read from the Immersion CyberGlove, for better sensor readings to be fed into an Artificial Neural Network. This is used to minimize the requirements of the calibration process. Analysis of all results and feedback is presented.

Subjects: subject: Health Sciences, Pharmacy.

description: Objective. This thesis tests the validity of a randomized controlled trial variant, the enrichment-discontinuation design (also called a randomized discontinuation design) against gold-standard classic RCT's using published trials of psychiatric drug therapy. Methods. A series of systematic reviews were conducted to identify all maintenance trials of mood stabilizers and antidepressants. Planned comparisons between enrichment discontinuation trials and gold standard classic RCT's were conducted. Finally, a sample of research literature was reviewed to identify the extent to which the limits of enrichment discontinuation trials were identified. Results. There was a non-statistically significant trend favoring drugs used in open phases vs classic RCT's. The lack of extended classic RCT's of psychiatric drugs is poorly recognized. Conclusion. Enrichment discontinuation designs dominated the evidence base supporting psychiatric drug maintenance. Bias cannot be ruled out. Limits to the design are poorly recognized in the literature.

description: L'intérêt ultime de cette thèse est d'observer si et comment les rapports entre l'État et les citoyens se transforment à l'ère du néolibéralisme et de la société du risque. Pour ce faire, nous avons privilégié un laboratoire particulier soit le débat politique concernant la mise sur pied de la Banque nationale de données génétiques. Compte tenu de sa centralité dans la définition du rapport entre l'État et les citoyens, nous avons questionné notre matériau pour découvrir la place faite à la présomption d'innocence dans le débat entourant l'instauration de cette technologie. Concrètement, la question qui guide notre recherche est: Comment les différents groupes de pression intervenus dans le processus législatif menant à l'adoption de la Banque nationale de données génétiques se représentent-ils la présomption d'innocence? Dans les mémoires des groupes de pression, nous avons analyse comment, à travers ce que les groupes disent, on peut percevoir leur conception de la présomption d'innocence. Nous avons pu dégager trois configurations, ou trois idéaux-types, des représentations de la présomption d'innocence: une présomption de risque, une présomption d'innocence relevant du libéralisme classique et une conception intermédiaire de la présomption d'innocence. Cette recherche, nous l'espérons, participe à combler un manque de connaissances empiriques sur la question de l'ADN en tant qu'objet sociologique et plus précisément sur l'ADN dans la justice criminelle.
Feminists Researching Fathering: What do we see through a reconciliation lens?

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Philosophy.

description: A reading of the fathering discourses in the Canadian equality feminist communities and the profeminist fathering communities reveals conflicting interests and beliefs, despite a shared goal of "gender equality." This thesis argues that identity conflict theory, most often applied to intractable ethnic and religious conflict, is relevant to the epistemological conflict between equality feminist and profeminist fathering communities. Further to this, it is demonstrated that the literature on the reconciliation of identity conflict can illuminate the challenges and potential for the uptake of a feminist research model focused on reconciliation of this gender-based conflict. Movement along the path toward a reconciliation approach can be seen within equality feminist research communities. The use of a peace and conflict lens to examine gender conflict in Canada draws attention to work being done by reconciliation scholars. This work may provide a map for forward movement toward the reconciliation of gender issues.
Microcystin production and the dominance of toxigenic strains of cyanobacteria in lake and culture studies

description: Cyanobacteria produce toxic compounds with the hepatotoxic microcystins being the most commonly encountered in freshwater. Microcystins are produced by several cyanobacterial genera and show large spatial and temporal variation in aquatic ecosystems as both toxigenic and non-toxigenic strains may co-exist and reach bloom levels. The regulation of microcystin production, the ecological or physiological role(s) of microcystins, and the factors that specifically promote toxic cyanobacterial blooms are not yet well understood. The first part of this thesis tested the role of light intensity in regulating the production and composition of microcystin congeners using laboratory culture experiments. The second part, using field observations and a lake enclosure experiment, examined the effects of physical, chemical and biological variables on microcystin concentrations and the growth of toxigenic cyanobacteria in a shallow, mesotrophic lake. Throughout, chemical and molecular based methods were utilized along with traditional culture and limnological methods in order to measure microcystin production and the presence of toxigenic cyanobacteria. Light intensity had a significant effect on microcystin concentrations and congener composition. However, there were no clear advantages of either toxigenic or non-toxigenic strains in terms of their ability to grow, compete for light resources, or dominate in a mixed-culture setting. The response of each strain of Microcystis aeruginosa was unique such that generalizations could not be made between toxigenic and non-toxigenic strains in terms of their competitive ability in nature; microcystin production did not appear to impair the competitive ability of toxigenic strains. In field studies of a shallow mesotrophic lake over two years, the number of microcystin gene copy numbers (mcyD) did not correlate well with microcystin concentrations. Both within the lake and across a nutrient gradient established in in situ enclosures, the best predictor of the presence of toxigenic strains was the actual biomass of potentially toxigenic genera (mainly Anabaena and Microcystis ), rather than any particular chemical or physical variable such as light. However, both environmental and biological variables were significant in predicting actual microcystin concentrations. The combination of molecular, chemical, and taxonomic data appears necessary to understand and predict toxic cyanobacterial blooms.

Simulation of axisymmetric round jet with and without coflow using vortex-in-cell method
Creators: name: Alatawi, Eid

Subjects: subject: Engineering, Mechanical.

description: The vortex-in-cell is developed to simulate an axisymmetric round jet with and without coflow. For an incompressible and viscous jet, the method consists in three fractional steps. The first fractional step describes the convection of interacting vortex elements. The second and third fractional steps simulate the diffusion of vorticity using the diffusion velocity method and the deterministic diffusion, respectively. For the jet with no coflow, the methodology is tested by initializing the vorticity field with one vortex sheet, multiple vortex sheets and with the Stokes stream function using one and multiple vortex sheets. Two inflow profiles are tested, the top hat profile and the jet self similar profiles. The sensitivity of the results to the number of vortex elements and grid size are presented and compared. Also, the effect of perturbing the top hat inflow velocity profile is investigated. The jet with coflow is investigated using top hat inflow velocity profile with one and multiple vortex sheets. The mean centerline velocity, streamwise mean velocity profile, vorticity contour, instantaneous distribution of vortex elements, root-mean-square longitudinal and lateral velocity fluctuations, cross-stream correlation are presented. The results are compared with previous experimental measurements and numerical simulation using vortex method.
The lived experience of being a trauma nurse: "Seeing through cloudy situations"

description: From the time of admission through rehabilitation, trauma nurses are faced with the challenges of caring for the survivors of traumatic injuries (Neff & Stinson-Kidd, 1993). Trauma unit nurses are responsible for detailed assessments, documentation of all events, management of crisis situations and providing continued emotional support of patients and family members. Research shows that care of the trauma patient places great cognitive, emotional and physical demands on the trauma nurse. However, the literature review indicated that limited work had been done which captured the perspectives of trauma nurses and no studies could be found which explored the meaning of being a trauma nurse. Therefore, a qualitative study using interpretive phenomenology was undertaken to describe the lived experience of being a trauma nurse. Four themes were revealed in the data analysis: "Being on guard all of the time," "Being caught up short," "Facing the challenge," and "Sharing the journey." The seven participants agreed that the essence of being a trauma nurse was captured in the metaphorical statement: "Seeing through cloudy situations." Despite the many challenges participants faced on a daily basis, they were able to see through the cloudy situations and find meaning and satisfaction in being trauma nurses. The negative aspects about being a trauma nurse were offset by the positive moments. (Abstract shortened by UMI.)
Treatment of dilute aircraft deicing fluid (ADP) using an anaerobic baffled reactor (ABR)

Subjects: subject: Engineering, Chemical.

description: Successful treatment of low strength aircraft deicing fluid (ADF) was achieved using the Anaerobic Baffled Reactor (ABR), under different hydrological retention times (HRT) and COD influent concentrations. A total of 17 experimental runs were conducted in continuous mode, achieving COD removal efficiencies of over 75% for most of the conditions tested. During this experiment different ADF concentrations (0.04%, 0.07%, and 0.13% v/v) were continuously fed at different HRTs (24, 12, 6 and 3 hrs) at organic loading rates (OLR) varying between 0.3 and 6 kg COD/m3/d. The performance of the reactor was determined by the COD removal efficiency at the different OLRs. The best COD removal was reached at high COD influent concentrations and HRTs, for the lowest HRTs essayed COD removal efficiency dropped to an average of 65% for the 3 COD influent concentrations tested. Methane production potential were close to the theoretical value of 0.39 L CH4/g COD removed at 35°C. The effect of biomass pre-acclimation was also evaluated and it was found to be effective in increasing specific acetoclastic activity for this type of wastewater in order to reduce the time needed for acclimation.

description: This work focuses on the technological environment of M-Commerce, and highlights some technological reasons slowing the penetration of this technology in North America1. The purpose is to provide some closure and present a potential solution that would improve the North American M-Commerce adoption level. The determined research hypotheses are: (1) Lack of adequate government regulations; (2) Lack of adequate spectrum; (3) Lack of adequate technologies; (4) Lack of adequate standardization process. An analysis and a comparison of these variables in the respective poles---Western Europe, Japan, North America---using their respective technology---GSM, I-Mode, CDMA is conducted. More specifically this in-depth comparative analysis helps determine if and how these variables impact the QoS2 and therefore the M-Commerce adoption outcome. The lack of adequate spectrum and the lack of adequate standardization process, in North America show to be the primary reasons for the slow adoption of M-Commerce. Hence, the conclusion of this work proposes an alternative solution. This proposal provides a new revised model of the North American M-Commerce value chain. This model would eliminate the identified issues and increase the Quality of Service, as well as the customer's satisfaction, resulting in higher adoption level. Furthermore, this potential new strategy gives North America the opportunity to reposition itself. 1North America: We define North America by Canada and The United States. However throughout this work we often used cases and examples related to the United States. The reason being, that the United States is leading the wireless telecommunication in North America. 2QoS: Quality of Service
Function of the cell surface receptor component integrin beta1 in human tumour cells

description: The work presented herein examines the potential impact of extracellular matrix (ECM) protein-integrin receptor interactions on tumour cell chemotherapeutic sensitivity, proliferation and anchorage-independent growth. First, a screen was performed to assess the impact of ECM proteins on the survival of various tumour cell lines treated with different chemotherapeutic agents, however no significant modulation by ECM was detected. To more specifically understand potential influences of ECM on tumour cell phenotypes, a siRNA approach targeting integrin beta1, an important ECM receptor component, was employed. Integrin beta1 depletion studies conducted in paired cisplatin sensitive and resistant ovarian cancer cells did not support a role for ECM-integrin receptor binding in drug sensitivity. Similarly, reduction of integrin beta1 protein using the siRNA approach did not impact the adhesion or adherent growth of the cancer cell lines studied. However, integrin beta1 was shown to be necessary for the anchorage-independent growth of all tumour cell lines tested in soft agarose colony formation assays. The importance of integrin beta1 for anchorage-independent growth of PC3 cells was further confirmed using both neutralizing antibodies to the receptor subunit and a signaling-impaired splice variant of integrin beta1. Depletion of the integrin ligand, fibronectin, from the tumour cell culture medium similarly reduced soft agarose colony formation, suggesting that ligation of beta1 integrins is necessary for anchorage-independence. Co-immunoprecipitation studies revealed the formation of a de novo interaction between beta catenin and integrin beta1 when tumour cells were transitioned to grow anchorage-independently. These findings suggest a model whereby ligation of the beta1 integrin-containing receptors by soluble fibronectin drives the anchorage-independent growth of tumor cells through a beta catenin signaling pathway.
