M. Phil. (Personal, Interpersonal and Professional Leadership) / Orientation: Personal experience of the phenomenon of transcendence and a preliminary literature review indicates that the phenomenon of transcendence can be better integrated within the Personal, Interpersonal and Professional Leadership (PPL) framework as well as within other leadership theories. Research purpose: The aim of the study is to conceptualise transcendence within PPL and leadership in general using auto-ethnography research methodology. Motivation for the study: Current leadership literature within PPL does not include the integration of the phenomenon of transcendence as a model towards spirituality and leadership. This gap can contextualise spirituality and leadership through transcendence. Research design: The research approach within this study was based a postmodernist qualitative philosophy. Auto-ethnography was used as methodology and also included a life history of another person to verify the auto-ethnographic data. Main findings: The study yielded an auto-ethnographic story with a rich and varied description of how a person can experience transcendence within the personal leadership field. The analysis of the collected data has revealed themes that can possibly contribute towards spirituality and leadership. Practical implications: The findings of this study might bring insight into the human ability of transcendence despite difficulty or suffering, and that can contribute to spirituality and leadership. Anticipated contribution: The study provides some understanding of how a person can still develop into a leader despite difficulties or hardship. This understanding can contribute to leadership development interventions, which can also be explored further in future.

Aplicamos este método a diversas configurações de circuitos, inclusive os com densidade de corrente superficial ou volumétrica, utilizando as fórmulas de Neumann, Weber, Maxwell e Graneau. Comparamos os resultados obtidos através do nosso método com os resultados obtidos por métodos de aproximação usuais. Concluímos que o nosso método é superior a estes últimos por possibilitar resultados algébricos com a ordem de aproximação que se queira. Para a auto-indutância de um circuito de corrente fechado de qualquer forma generalizamos a equivalência entre as quatro fórmulas citadas acima. A força entre elementos de corrente foi analisada na segunda parte deste trabalho. Através do aperfeiçoamento de um método de cálculo de força entre partes em contato de um circuito único, comparamos as expressões de Ampère e Grassmann em diversas configurações, também incluindo aquelas com densidade de corrente superficial ou volumétrica. Concluímos que estas duas expressões são equivalentes em todas as situações de circuito de corrente fechado. Apresentamos uma demonstração deste fato. Por último, analisamos a existência de força longitudinal entre condutores de corrente com a força de Weber, e concluímos que ela não é capaz de explicar a ordem de grandeza dos resultados experimentais com explosão de fios, no caso estacionário / Abstract: In this work we present a method for inductance calculation. We apply this method to various configurations of circuits, including the ones with surface or volumetric current density, using the formulas of Neumann, Weber, Maxwell and Graneau. We compare the results obtained with our method to the ones obtained with the usual approximation methods. We conclude that our method is more powerful than the last ones, because it allows one to obtain algebraic results with the degree of approximation desired. For the self-inductance of a closed circuit with arbitrary shape we generalize the equivalence between the four formulas cited above. The force between current elements was analized in the second part of this work. We improved a method for force calculation between parts in contact of a single circuit, and use it to compare the expression of Ampere to the expression of Grassmann in various configurations of circuits, also including the ones with surface and volumetric current density. We conclude that these two expressions for force between current elements are equivalent to one another in all situations of closed circuits. We present a demonstration of this fact. Finishing, we analyze the existence of longitudinal force between current carrying conductors with Weber's force, and we conclude that it is not able to explain the magnitude of the experimental results with exploding wires, in steady state / Doutorado / Física / Doutor em Ciências

O AGV/LCA foi projetado para aplicações no meio industrial, fazendo parte de um sistema de transporte flexível, servindo como meio de integração de matéria-prima e ferramentas. O sistema de orientação utiliza fitas refletivasfixadas no piso e o veículo tem o seu controle através de um programa executado em um microcomputador compatível com um PC/AT - 386 Sx, a bordo do AGV. Os sistemas de tração e direção são baseados em motores de indução trifásicos do tipo gaiola de esquilo, alimentados por inversores do tipo fonte de tensão, configurados topologicamente em ponte trifásica. Este trabalho tem como objetívo principal a integração entre os diversos subsistemas -aquisição de dados, controle de tração e controle de direção -através de um programa que faz o controle das operações do AGV. São mostradas as funções implementadas para garantir o bom desempenho do sistema, como a compensação de tensão dos motores operando em baixas frequências e o perfil suave de variação de velocidade do carro. São feitas a modelagem do sistema e o projeto do controlador através da técnica de alocação de pólos e são mostrados resultados de simulações em computador digital com o sistema em malha fechada, de forma a validar as considerações feitas no projeto do sistema de controle e também para se obter referências para a implementação prática / Abstract: The Computer Engineering and Industrial Automation Laboratory of the UNICAMP's Electrical Engineering Faculty (LCA/FEE), has been developping the design and implementation of an Automated Guided Vehicle -AGV. The AGV/LCA was designed to work in industrial environment as a Flexible Transportation System, integrating raw material and tools. The track is based on a reflectivetape on the floor and the AGV's control is made by a microcomputer PCIAT -386 SX, aboard the vehicle. The traction and steering are based on three phase squirrel-cage induction motors, fed by voltage source inverters, topologically configurated in a three phase bridge. The main purpose of this work is to integrate the subsystems -data acquisition, track control and steering control -by a software that controls alI operations. We show the implemented functions to guarantee the desired performance, such as the motors voltage compensation when operating in low frequencies and the vehicle's speed variation behavior. The system modeling, and the control design by the pole placement method are made, and closed loop system's simulation in a digital computer are shown, in order to make valid the theoretical considerations and to obtain practical implementation references / Mestrado / Mestre em Engenharia Elétrica

Les anticorps sont des protéines en forme de Y, trouvées comme composant du sérum circulant, qui aident le système immunitaire à cibler et à répondre aux agents pathogènes et aux molécules étrangères, mais peuvent aussi contribuer à la maladie en réagissant aux protéines constitutives. Les anticorps sont produits par des Plasmocytes, qui les sécrètent dans la circulation. Parce qu'il n'y a pas de lien physique entre les plasmocytes et leurs anticorps sécrétés, la détection d'anticorps spécifiques d’un antigène est problématique. Dans cette thèse, j'explore l'utilisation de la microfluidique en gouttelettes pour générer et manipuler des compartiments aqueux homogènes dans lesquels des cellules sécrétant anticorps peuvent être isolées et analysées à haut débit a'échelle d'une seule cellule. Pour caractériser les cellules sécrétant des anticorps à l'intérieur des gouttelettes, j'utilise un nouveau test qui permet d'interroger les cellules en fonction de la spécificité de leur sécrétion. Ces compartiments de gouttelettes peuvent être triés pour le séquençage d'anticorps, ou analysés au cours du temps pour obtenir des informations cinétiques de l'interaction anticorps-antigène à l'intérieur de chaque gouttelette. En utilisant une nouvelle technologie, j'ai pu obtenir le répertoire d'anticorps de souris immunisées contre deux antigènes différents à partir de cellules sécrétant des anticorps spécifiques d’un antigène, avec des capacités égales ou supérieures aux technologies disponibles actuelles. Aussi, j'ai pu suivre le processus de maturation d'affinité des anticorps à l'échelle de la cellule unique, à la fois dans l'immunisation et la maladie auto-immune. Avec ces outils, je démontre comment la microfluidique peut être utilisée pour caractériser les réponses immunitaires et auto-immunes à travers l'évaluation de cellules sécrétant des anticorps. / Antibodies are Y shaped proteins, found as a component of circulating serum, that help the immune system target and respond to pathogens and foreign molecules, but can also contribute to disease when reacting to constitutive self-proteins. Antibodies are produced Plasma Cells, which secrete them into circulation. Because there’s no physical link between Plasma Cells and their secreted antibodies, the detection of antigen-specific antibodies is problematic. In this thesis I explore the use of droplet microfluidics to generate and manipulate homogeneous aqueous compartments in which single antibody secreting cells can be isolated and analyzed in a high-throughput manner. To characterize single antibody secreting cells inside the droplets I use a novel assay that allows to interrogate cells based on the specificity of their secretion. These droplet compartments can be sorted for single cell antibody sequencing, or analyzed over time to obtain kinetic information of the antibody-antigen interaction inside each droplet. Using new established technology I was able to obtain the antibody repertoire of mice immunized against two different antigens from single antigen-specific antibody secreting cells, with equal or better capacities than current available technologies. Also, I was able to follow the affinity maturation process of antibodies at the single-cell level, both in immunization and autoimmune disease. With these tools I demonstrate how microfluidics can be used to characterize the immune and the autoimmune responses through the evaluation of single antibody secreting cells.

This research was developed in the light of Albert Bandura' Social-Cognitive Theory. This Social-Cognitive Theory was once labeled as Social Learning Theory. This modification helped holding off it from existing theories of learning and emphasize the role that cognition plays on people's ability. Therefore, self-efficacy beliefs are beginning to be studied as an important factor on the development of people in solving tasks. Seventy nine students took part in this research, divided among the ninth year of elementary school (45 students) and the third year of high school (34 students), of both sexes, aged between fourteen and eighteen. The tools used were: 1) self-efficacy scale; 2) math's self-efficacy exam; 3) mathematic exams with arithmetic and geometry content; 4) semi-structured interviews with students who had higher and lower self-efficacy beliefs of each grade. The analyzed results demonstrate that: 1) Students who have higher self-efficacy beliefs have better performance in solving problems and in everyday school life, 2) Students who believe more in their ability to solve mathematical problems have better performance in problem solving; 3) There were no significant contrast between beliefs of self-efficacy and p...

Advanced combustion concepts are required to meet the increasing global energy demand and stringent emission regulations imposed by the governments on automobile manufacturers. Improvement in efficiency and reduction in emissions can be achieved by downsizing the Spark Ignition (SI) engines. The operating range of SI engine is limited by occurrence of knock, pre-ignition and the following super-knock due to boosting of intake pressure, to account for the reduction of power, as a result of downsizing the engine. Super-knock, which represents high momentary pressure accompanied with pressure oscillations, is known to permanently damage the moving component of the engines. Therefore fundamental comprehensive understanding of the mechanism involved in pre-ignition and super-knock are required to design highly efficient spark ignition engines with lower emissions that can meet the increasing government regulations. \nThe thesis focuses on auto-ignition characteristics of endgas and the bulk mixture properties that favor transition of pre-ignition to super-knock. Direct numerical studies indicate that super-knock occurs to due to initiation of premature flame front that transition into detonation. In literature, many sources are reported to trigger pre-ignition. Due to the uncertainty of the information on the sources that trigger pre-ignition, it is extremely difficult to predict and control pre-ignition event in SI engines. Since the information on the source of pre-ignition is not available, the main focus of this work is to understand the physical and chemical mechanisms involved in super-knock, factors that influence super-knock and methods to predict super-knock. \n
Pre-ignition was initiated at known locations and crank angle using a hotspot of known size and strength. Different parametric cases were studied and the location and timing of pre-ignition initiation is found to be extremely important in determining the transition of pre-ignition event to super-knock. Pre-ignition increases the temperature of the endgas and the overall bulk mixture, that transitions the pre-ignition flame front to a detonation. The transition of the flame propagation mode from deflagration to detonation was investigated with different type of analysis methods and all results confirmed the transition of pre-ignition flame front to detonation that results in super- knock.

Evidence exists today which indicates that our present motor carrier regulatory system, rather than "protect the public interest", might actually inhibit the efficient provision of transportation services to the economy. Accepting such a view of the regulated motor transport market as valid, this thesis could serve as a model from which legislators might begin to re-write our motor carrier act. It is assumed throughout this work that such an undertaking is well overdue. The possible use of this thesis for such a purpose is its primary justification for existence. In order to serve as a basis for such a legislative revision, the model and recommendations contained herein should be designed to maximize the potential benefits which might accrue to the industry and the shipping public. The philosophical bias flowing throughout this work is the conviction that this maximization of benefits could best be realized through increased competition among firms, coupled with the minimization, through reduced regulation, of any economic threats to the stability of the national transportation system. Thus, the attempt is made in the model to be presented to provide for an increased level of industry competition while retaining those essential elements of regulation upon which the national transportation policy was originally based. The approach taken in this work is one of review, description, analysis, model-building and commentary. The current regulatory issues of concern to the motor transportation industry are reviewed in chapter 2. The market structure is described in chapter 3, followed by an analysis of price and output determination in chapter 4. The framework for a new approach to price determination in this industry is developed in chapters 5 and 6. The model presented is intended to replace many of the regulatory procedures in use today. Chapter 7 contains comments on the relevance to the industry of the model constructed in chapters 5 and 6, to include a discussion of its probable impact upon several of the most perplexing problems facing regulators today. The appendix was added to enhance the reader' s und er-st.and.i.ng of the extent to which present-day regulated motor transport rate structures fail to represent rational and economically justifiable charges for services rendered. This thesis will not continue in the modern trend of regulatory literature--that is, resorting to emotionalism and allegations aimed at removing regulation from the transport industry (16). Nor is its purpose to justify the oontinued existence of the Interstate Commerce Commission. Rather, the admittedly ambitious goal of this work is to present what is felt to be a much-needed new format for regulation in this field--one based upon the ideals of economic theory, the tenets of national transportation policy, and the restraints of present-day market realities. With this goal in mind, every attempt will be made to announce assumptions, identify opinions and employ rigid economic analysis whenever possible.
