Em perspectiva histórica, esta tese analisa a trajetória da Rua Direita com base em fontes primárias inéditas e jamais seriadas dessa forma. Como uma metonímia, em que a parte representa a dinâmica do todo, por meio do estudo da transformação da rua buscou-se analisar o processo de transformação do Centro Histórico de São Paulo em suas interfaces com a cidade. Partindo dos Maços de População e das Décimas Urbanas, foram inventariados - lote a lote - proprietários, usuários, tipologia e usos, desde o século XVIII, quando ali moravam em casas de taipa de pilão os mais ricos comerciantes de São Paulo que geralmente vendiam tecidos para vestuário (as chamadas \'fazendas secas\'). Resultado da grande expansão da economia cafeeira, no século XIX observamos uma profunda alteração na arquitetura da rua, reconstituída com base nos documentos da Série Obras Particulares do Arquivo Histórico de São Paulo. Para consecução dos objetivos, elaboramos uma metodologia inédita de cruzamento de fontes conexas e diversas, envolvendo as supracitadas além de fotos, mapas, almanaques, memoriais, inventários post-mortem, etc. A ideia era espacializar o processo de mudança, sem perder de vista as permanências ao longo do tempo. No início do século XX, a Rua Direita passou a ser o centro das atenções e negócios novos da Metrópole do Café que alteraram seu perfil e sua arquitetura. Cresceu em comprimento e em movimento com a implantação do Viaduto do Chá e depois foi encurtada, mas valorizada, com a abertura da Praça do Patriarca. Nas décadas de 1920 a 1950 retomou sua vocação inicial de polarizadora do comércio de tecidos finos, mas, com o advento do Centro Novo, declinou em importância. Pouco se verticalizou até a década de 1950, mantendo a maioria dos imóveis, mas alterando aos poucos o perfil dos usos e usuários novamente, transformando-se um eixo de comércio de vestuário de baixo preço. Entre 1950 e 1977, voltou a se verticalizar ganhando oito arranhacéus de uso misto, com conjuntos de salas e lojas no térreo, numa época em que a Avenida Paulista e a Avenida Faria Lima estavam apenas se insinuando no cenário. De 1988 a 1991 foram tombados seus principais edifícios pelo Conpresp, assim como os das imediações, acompanhando a tendência iniciada com o Pátio do Colégio em prosseguimento às iniciativas do Condephaat. / In historical perspective, this thesis analyzes the history of Rua Direita based on unpublished primary sources never previously ordered in this way. As a metonymy, in which a part stands for the dynamics of the whole, the aim of studying the transformation of this street was to analyze the process of transformation of São Paulo\'s historic center and its interfaces with the city. Based on census and tithe data (Maços de População and Décimas Urbanas) a lot-by-lot inventory was compiled for owners, users, types and uses, from the 18th century when São Paulo\'s richest merchants lived on Rua Direita in houses made from pressed earth and usually sold fabrics for clothing (called \'dry goods\'). The 19th-century boom in the coffee economy led to far-reaching changes in the street\'s architecture, which have been reconstituted based on documents from São Paulo\'s Historic Archive. We developed a new method to cross-check different sources, involving the above data and photographs, maps, almanacs, memoirs, postmortem inventories, etc. The idea was to spatialize the change process without losing sight of continuities over time. In the early 20th century, Rua Direita became the center of attention and new business for the city now named the \'coffee metropolis\', modifying its profile and architecture. It was lengthened and bore more traffic when a bridge was added (Viaduto do Chá) and then shortened, although gaining value, when a new plaza (Praça do Patriarca) was laid out. From the 1920s through the 1950s, it regained its original purpose as a center for fine fabric traders but later declined in importance when a new downtown district (Centro Novo) was built. There were few high buildings until the 1950s; most properties remained unaltered but profiles of uses and users gradually changed again as it became an area for the low-price garment trade. From 1950 through 1977, 8 more high-rise buildings were erected for mixeduse office suites and stores on the ground floor, at a time when Paulista and Faria Lima Avenue were just beginning to show on the scenario. From 1988 to 1991, the street\'s main buildings were listed by municipal heritage entity Conpresp, as were its surroundings, following a trend that had started when the founding fathers\' building (Pátio do Colégio) was listed by the state heritage entity Condephaat.

This present paper has as its main focus the study of the straight and of the circumference under a vector approach. Initially the necessary vectors concepts are introduced so the subject can be comprehended under de nitions and propositions, so the reader (high school's student) take ownership of the vector's ideas in plan and space and, above all, understand all the main vectors' properties, with which will be de ned the equations of the straight and of the circumference. It introduces the de nition of the equipolency given by Giusto Bellavitis see it at [2] (that is basically the vector's de nition that is known nowadays) and also the de nition of linear dependence and independence, angle between two vectors, opposite vectors and internal product. It is also observed that all de nitions and mentioned properties in the plan are valid in space R3. Finally it is de ned the straight's equation (using the idea of product by scale) and, the circumference equation (using the rule de nition). / De acordo com [1] o estudo de vetores, retas e planos é bastante útil aos estudantes do último ano do ensino secundário (hoje Ensino Médio), principalmente àqueles que desejam cursar engenharia, física, matemática ou química. Esse trabalho tem como objetivo o estudo da reta e da circunferência sob uma abordagem vetorial. Inicialmente são introduzidos os conceitos vetoriais necessários à compreensão do assunto, sob forma de de nições e proposições, para que o leitor (aluno do Ensino Médio e ou professor) se aproprie das ideias de vetores no plano e no espaço e, sobretudo, entenda as principais propriedades de vetores, com as quais serão de nidas as equações da reta e da circunferência. Introduz-se a de nição de equipolência dada por Giusto Bellavitis, veja [2] (que é basicamente a de nição de vetor que se conhece nos dias atuais) e também as de nições de dependência e independência lineares, ângulo entre dois vetores, vetores opostos e produto interno. É também observado que todas as de nições e propriedades mencionadas no plano são válidas no espaço R3. Por m é de nida a equação da reta (usando a ideia de produto por escalar) e, a equação da circunferência (usando a de nição de norma).

Mapa conceitual (MC) é uma técnica de organização e representação do conhecimento através de uma rede proposicional. Ainda que utilizado no âmbito da educação formal poucos trabalhos mencionam a importância e necessidade da capacitação na técnica para que se possa desfrutar de seus benefícios. Este estudo desenvolveu um instrumento para avaliar o nível de conhecimento de mapeadores após o processo de capacitação em MCs. A tabela de clareza proposicional, o MC semiestruturado e a aprendizagem colaborativa expandida foram três estratégias instrucionais desenvolvidas a fim de permitir que os alunos compreendessem os quatro conceitos centrais do mapeamento conceitual: proposição, questão focal, recursividade e hierarquia. Um questionário (escala Likert 5-níveis) contendo cinco afirmações foi desenvolvido, validado (? de Cronbach 0,902) e aplicado para medir a compreensão dos alunos sobre os MCs. Os questionários (n = 232) foram coletados na última aula da disciplina Ciências da Natureza, oferecida aos alunos ingressantes da Escola de Artes, Ciências e Humanidades (EACH/USP Leste) em 2009 e 2010. Quatro turmas receberam treinamento sistemático em MCs (grupo experimental) enquanto uma turma não recebeu o mesmo treinamento (grupo controle). A análise dos dados envolveu o tratamento estatístico de comparação entre médias por teste-t de Student e a estatística multivariada exploratória com métodos de reconhecimento de padrões através das análises hierárquica de agrupamentos (HCA) e de componentes principais (PCA). O resultado do teste-t confirmou que o questionário foi capaz de diferenciar alunos do grupo experimental em relação ao grupo controle. A HCA agrupou os alunos de acordo com seu nível de entendimento em mapeamento conceitual e a PCA, além de corroborar com os resultados da HCA, indicou que o entendimento da clareza semântica de proposições e da importância da pergunta focal são críticos para se tornar proficiente na técnica. / Concept Map (Cmap) is a technique to organize and represent knowledge through a propositional net. Although the fact that concept maps are used in formal education context few papers has mentioned the importance and necessity of a straight-forward training session on the technique, which allow to enjoy its benefits. This study develops an instrument to assess the level of knowledge of mappers after the straight-forward training session. The propositional clarity table, the half structured Cmap and the expanded collaborative learning were the three strategies responsible to guarantee the understanding of four central concepts in conceptual mapping: proposition, focal question, recursivity revision and hierarchy. Five statements\' questionnaire (five-level Likert\'s scale) was developed, validated (Cronbach\'s alpha 0.902) and tested to assess the students\' understanding about Cmaps. Those questionnaires (n = 232) was collected on the last class of Natural Science course offered to first year\'s students of the Escola de Artes, Ciências e Humanidades (School of Arts, Science and Humanities - University of São Paulo) in 2009 and 2010. Four classes was systematic trained (experimental group) and one class does not received the same training (control group). The data analysis involved the statistical treatment to comparison between the means by Student\'s t-test and non-supervised exploratory multivariate analysis for pattern recognition by Hierarchical Cluster Analysis (HCA) and Principal Component Analysis (PCA). The results of t-test confirmed the questionnaire capability to distinguish the students of experimental from control group. HCA clustered the students according to their knowlodge level in concept mapping. PCA not only agree with the HCA results but also demonstrated that the understanding of propositional clarity semantic and the importance of focal question are critical to students that desire to be proficiencies in Cmaps.

A inserção de gotejadores em uma tubulação modifica as linhas de fluxo, provocando turbulência local, que resulta em perdas de carga adicionais maiores que as perdas contínuas na tubulação. Para avaliar a perda total de carga, ao longo da linha lateral de gotejadores, as perdas contínuas e as localizadas, devidas à presença dos emissores no tubo, devem ser consideradas. Este trabalho apresenta os resultados de um experimento conduzido para avaliar as perdas localizadas de carga em gotejadores coaxiais integrados em tubos de polietileno. A perda de carga para diferentes vazões foi determinada em quatro modelos de tubos gotejadores, com sete repetições. Cada segmento de tubo utilizado continha 11 gotejadores. Para cada vazão, a perda localizada de carga foi calculada pela diferença entre a perda de carga no tubo com emissor e a perda de carga continua no tubo uniforme, estimada pela equação de Darcy-Weisbach. Aproximações matemáticas foram sugeridas para calcular a perda de carga com base no coeficiente de carga cinética (K) e em um valor constante de comprimento equivalente (Le). Para cada modelo de tubo gotejador, o coeficiente K foi praticamente independente do número de Reynolds, para R > 10 000, sugerindo que cada gotejador pode ser caracterizado por um valor médio de K, obtido em função de um índice de obstrução. Em decorrência, propôs-se uma alternativa para calcular a perda localizada de carga, provocada por gotejadores coaxiais integrados a tubos de polietileno, em função de relações geométricas entre a área de escoamento através do gotejador e a da seção do tubo. Os resultados encontrados possibilitam concluir que: (a) maior variabilidade dos valores de K ocorreu para os gotejadores não-autocompensados e a maior perda localizada de carga para os autocompesados; (b) o aumento do grau de obstrução (1 - Ag/At) proporcionou o aumento na perda localizada de carga. Considerando a vazão de 20 x 10-5 m3 s-1, nos tubos gotejadores Amanco, observou-se que o aumento de 1,79 vez no grau de obstrução resultou no aumento de 3 vezes na perda localizada de carga; já nos gotejadores Naandan, o aumento de 2,2 vezes no grau de obstrução proporcionou o aumento de 8,9 vezes na perda de carga; (c) a consideração da perda localizada de carga é um critério relevante no dimensionamento de linhas laterais de gotejamento, especialmente quando se utilizam gotejadores autocompensados. A desconsideração da perda localizada de carga levou à superestimativa do comprimento máximo da linha lateral de até 25,7%, para os gotejadores autocompensados, e de 9,5%, para os não-autocompensados; (d) o cálculo da perda localizada de carga, utilizando o modelo potencial para estimar o valor de K em função do índice de obstrução, mostrou bons resultados, comparáveis àqueles obtidos com o valor de K ajustado pelos dados observados em laboratório, o que resultou em pequenas variações na estimativa do comprimento máximo da linha lateral por esses dois procedimentos. Considera-se, assim, que a perda localizada de carga em gotejadores coaxiais, pode ser calculada utilizando-se um coeficiente de carga cinética calculada em função do índice de obstrução. / The insert of the drip in a pipe modifies the flow line, causing local turbulance, which results in more additional head loss than the continued loss in pipes. In order to evaluate the local head loss, along the drip irrigation laterals, the continued and localized loss due the presence of these emitters inside the pipes must be considered. This work shows the results of an experiment carried out to evaluate the local head loss in coaxial drippers integrated to polyethylene pipes. The head loss for different discharges was determined using four drip pipe models, using seven repetitions. Each pipe segment contained 11 drips. For each discharge, the local head loss was calculated by the difference between head loss in the pipe with emitters and the continued head loss in the uniform pipe, estimated by Darcy-Weisbach equation. Mathematical approaches were proposed to calculate the head loss based on the kinetic head coefficient (k) and in a equivalent length of pipe constant value (le). For each drip pipe model, the k coefficient was considered independent from Reynolds number, R >10.000. It can be concluded that each drip can be characterized by an average k, obtained in function from a obstruction index. As a result, it was proposed an alternative to calculate the local head loss caused by coaxial drip integrated to polyethylene pipes, according to geometric relationship between the flow area through the drip and the pipe section. According to the results can be concluded that: (a) the not self-compensated pressure emitters showed more variability in k values and the self-compensated showed greater local head loss; (b) the obstruction index increase (1 ag/at) caused an increase in the total head loss. Considering a discharge 20 x 10 -5 m3 s-1, it was observed in Amanco drip that a 1,79 times increase in obstruction index, resulting in 3 times the head loss and in Naandan drip, it was observed that 2,2 times increase in obstruction index, resulting in 8,9 times the head loss; (c) the head loss is a relevant criterion in the drip laterals design, especially for self-compensated drips. The disregard of the local head loss resulted in a over-estimate of 25,7% in the maximum length lateral, for self-compensated drips, and until 9,5% for not self-compensated drips; (d) the calculation of the local head loss using the potential model to estimate k value, according to the obstruction index, showed good results when comparing to those obtained using k factor adjusted to the observed data in the laboratory. Resulting in few variations in the maximum length lateral estimation for both procedures. It is considered that the local head loss, caused by the integrated drip on drip lateral, can be calculated using kinetic head coefficient according to obstruction index.

This diploma thesis deals with the impact of legislation on information system in a particular bank institution. Based on the proposal of European Market Infrastructure Regulation it identifies areas where the bank institution does not fulfill the regulation requirements. The thesis also tries to suggest existing processes adjustment and guarantee for them the support of information systems. During the existing processes investigation it discovers other weaknesses and suggests solutions leading to their elimination. These solutions would also lead to acceleration and increase in efficiency within the Straightthrough Processing model. The thesis devotes to all points of European regulation which should be fulfilled in the bank institution's point of view. First the current situation and then the solution of the particular point are mentioned. The thesis looks more detailed into central clearing. There are analyzed possible options in the process point of view. The impacts on the information system are specified for the chosen and most appropriate option. In order to secure the compact understanding of investigated issues, the thesis includes relations of European Market Infrastructure Regulation to the BASEL III concept, regulation supervision authorities in the European Union or introduction to functioning and core of financial derivatives.

The study compared an experimental group (n=26) who participated in weekly SIS sessions as an adjunct to existing treatment protocols for a period of 6-8 weeks, to a control group (n=14) who matriculated in treatment without the addition of SIS training for a period of 6-8 weeks. Subjects completed a battery of questionnaires at the beginning of the measurement period and at the end of the measurement period. The SASSI-2, The McMaster Family Assessment Device (FAD), and the Rotter Internal-External Locus of Control Scale were used to measure groups on recovery related variables at Pre-Test and Post-Test. Results demonstrated a consistent pattern of improvement over the time measure. The results of the interaction of group and time demonstrated a pattern of gains which did not reach statistical significance, partially as an artifact of the small sample size. An investigation of effect sizes was conducted to detect the effect of SIS training. The training was found to have a moderate effect size, which was consistent with other research using SIS training. Some areas for possible future research were addressed.

Mycenean society on mainland Greece started to decline with the collapse of the palatial system during the 13th century BC. Following the collapse was a big change in the ceramic repertoire of the Aegean area, this new period was later named the post-palatial period or late helladic IIIC which was based on the types of ceramics found during the period. The changes in the societies of the Aegean can be seen in the ceramics, which is one of the best-preserved materials from Mycenaean society. The changes are believed to have had a major impact on both the production and consumption of ceramic containers, which can be seen in the styles that were typical of the Greek mainland, but also in the spatial distribution and the use of ceramics. The purpose of this study is to analyze a ceramic object (an alabastron) from Uppsala University Museum Gustavianums antiquities collection and through the study find out how the object fits into the changes that took place in Mycenaean society around 1200 BC. The essay and the questions are mainly based on the ceramic object analyzed in the main part of the essay, where the purpose is to document and then analyze the vessel's manufacture, function, shape, decoration and the context. In this essay, theory and method is based on Panofskys’ framework for studies of iconography and iconology.

Background: Low back pain (LBP) is often associated with lumbar spinal instability (LSI). The multifidus muscle is considered a stabilizer of the spine and has been studied extensively with Rehabilitative Ultrasound Imaging (RUSI). There may be a relationshipbetween clinical signs of LSI, decreased cross-sectional area (CSA) of the multifidus and weakness. Having the ability to detect multifidus weakness without the use of RUSI may serve to be invaluable to the clinician in detecting multifidus weakness.Purpose: To investigate the relationship between the modified prone straight leg raise test (MPSLR) and CSA of the multifidusmuscle as measured by RUSI and to investigate the relationship between MPSLR and RUSI findings with the presence of low back pain symptoms that interfere with regular daily activities. Subjects: Participants consisted of two groups of subjects. One group (n=30, 87% male) comprised individuals in general good health, aged 18-55, without history of back pain. The second group (n=36, 56% male) comprised individuals aged 18-55, with history of low back pain within the past 12 months. Methodology: Subjects performed a MPSLR test to identify multifidus weakness. All subjects repeated the same test with concurrent RUSI to visualize the multifidusand measure its CSA. Results: A significant association between a positive MPSLR, asymmetry of the multifidus, and pain was observed (p r = .049, p = .696) was not observed. A sensitivity of 94% and a specificity of 63% was also discovered in the ability of the MPSLR test to detect asymmetry of themultifidus muscle within subjects. A positive MPSLR combined with a high Oswestry score of 25-30 further reinforced the probability of pain (p < .001) Conclusion: The MPSLR test demonstrated a strong association between a positive test and asymmetry of themultifidus muscle within subjects. Clinical Relevance: The MPSLR test can be used to identify patients at risk for LBP symptoms due to asymmetrical changes in the multifidus muscle of the lumbar spine, and aid in directing an appropriate rehabilitation approach to those patients in need of specific multifidus exercise prescription.
