O estudo procura avaliar decisões de produção de uma unidade de negócios partindo de conceitos de finanças corporativas como teoria de portfólio, modelo CAPM e a security market line. Em particular, buscou-se avaliar as opções de decisões de investimentos, buscando maximizar o valor da unidade, observando o risco percebido para cada linha de produtos da unidade de negócios. Através do cálculo da geração de caixa e dos investimentos necessários em capital de giro e ativos fixos para cada linha de produto, buscou-se criar a fronteira eficiente da unidade. A partir desta análise, avaliou-se também, dentro dos fatores estudados, quais mais afetam a variabilidade dos resultados apresentados. Foi feita também uma análise para determinar qual seria o efeito, sobre o resultado da unidade, caso o fator mais relevante encontrado fosse minimizado (melhorado). Demonstrando-se assim a relevância que uma determina ação pode ter sobre os resultados da empresa. Por último, criou-se um esboço de possíveis fatores externos ao estudo, como por exemplo, questões estratégicas, que devem ser avaliadas, em conjunto aos dados apresentados, como forma de se obter uma visão mais global da empresa. A metodologia desenvolvida na presente dissertação foi apresentada à empresa, no contexto das suas atividades. Além de ter obtido uma boa receptividade, foi possível identificar ações a serem empreendidas para deslocar o mix de atividades em direção à fronteira eficiente.

Até os dias de hoje, a abordagem estática tem sido a usualmente empregada para a avaliação da resposta de cabos de Linhas de Transmissão (LTs), apesar da resposta dinâmica ser, em muitos casos, reconhecidamente importante na avaliação do desempenho dos cabos. Para uma análise completa, não se pode desconhecer a natureza dinâmica da maioria dos fenômenos a que as LTs estão submetidas, sendo exemplos típicos as excitações mecânicas causadas pela ação do vento (carregamentos de baixa e alta freqüência) e a ruptura de cabos. Cabe salientar que mesmo a análise estática empregada tem sido simplificada, considerando normalmente apenas casos contemplados com soluções analíticas. A justificativa para emprego da análise estática baseia-se no menor esforço numérico exigido. Entretanto, essa justificativa já não se sustenta dado os grandes avanços na área computacional, possibilitando o estudo do desempenho de LTs na ocorrência de fenômenos que provocam carregamentos dinâmicos. Adicionalmente, há uma crescente demanda para que se obtenha um melhor entendimento de muitas questões relativas ao comportamento dinâmico das LTs, que possam explicar desempenhos observados e/ou sustentar o desenvolvimento de novas alternativas mais arrojadas de projeto e construção Entre os diversos métodos utilizados na engenharia estrutural, a integração direta das equações do movimento, através de métodos numéricos como as diferenças finitas centrais, se constitui numa poderosa ferramenta de cálculo. Esta ferramenta possibilita o tratamento de problemas envolvendo não linearidades geométricas e do material, como são os casos onde se avalia a resposta de cabos suspensos submetidos a carregamentos variáveis no tempo. Esta pesquisa objetiva a aplicação do método da integração direta das equações do movimento na análise de feixes de cabos de LT, quando submetidos à ação de carregamentos mecânicos variáveis no tempo, principalmente à excitação de ventos oriundos de fenômenos com natureza complexa (tormentas elétricas, por exemplo). É apresentado um método para determinar a resposta dinâmica de feixes que considera a interação entre o vento incidente e o movimento do condutor. A solução é obtida por integração numérica, no domínio do tempo, das equações de movimento de um modelo tridimensional não-linear discreto de feixe, as quais definem as forças nos espaçadores e cabos através de coeficientes aerodinâmicos obtidos experimentalmente. Também são apresentados modelos dos fenômenos meteorológicos mais comuns em nosso país (Brasil): tormenta extratropical (EPS) e tormenta elétrica (TS) Como ilustração, são apresentados exemplos de modelagem de vãos de LTs com condutor singelo e com feixes de condutores. Os exemplos demonstram a capacidade de avaliação de Estados Limites relacionados à distância relativa entre subcondutores, à estabilidade do feixe, à representação das suas propriedades e ao comportamento dinâmico, bem como aos carregamentos transmitidos às estruturas. A análise emprega conhecidas relações constitutivas para representar o comportamento tensão-deformação dos cabos. O enfoque utilizado possibilita a avaliação mais precisa de casos reais que ainda não podiam ser convenientemente tratados, além de permitir a extensão para estudos bem mais complexos, tais como feixes com disposições assimétricas.

A criação artística é proposta como um processo de pensamento na filosofia de Gilles Deleuze. Com este enfoque, a hibridação com a tecnologia digital é vista como uma estratégia potencializadora da criação e da produção na área artística a partir da geração de linhas de fuga - desencadeadoras de desterritoria/izações e reterritoria/izações na produção de sentidos no universo de sala de aula de uma disciplina teórico-prática na graduação. Uma cartografia dos acontecimentos experimentados pelos alunos permitiu flagrar linhas de fuga geradas pela hibridação no p/ano de composição (processo de criação e fruição) e no p/ano teórico (que envolve os planos científico e filosófico) com a tecnologia digital. A hibridação foi incrementada e visualizada por meio de atividades teóricopráticas em pequenos grupos, que foram retomadas em grande grupo a partir do processo de fruição da produção de aula.

The organizations are characterized as dynamic spaces, they are being revisited and redefined, because they constitute structural human spaces and new vain outlines won expression. As it begins, of the non consensus in its conception, it is explicit the complexity degree that is identified in the plurality and diversity, brought by the people that compose them, characterizing it as accomplishment space, of happiness and also of conflict, of relationships of power and organizational limits and from birth and burial of faiths, values, norms, symbols, knowledge and rituals, therefore, deeply human. In that way, to know the administration of the organization is preponderant condition for the format of the human relationships to be delineated in its living. Like this the work makes an option in knowing the social administration, this work tries to know and analyze the values and beginnings of the social administration; revealling characteristics and specificities of the organizational performance of UNIPOP that contribute to the formation of the conception of Social Administration, it tends as source of the information the managers of the institution; to identify the formative values of UNIPOP that contribute to the youths' partner-political action in the community, tends for reference the current students of the organization and last to evaluate values structurates and supporting that interconnection between the organizational Administration, formation youth's program, participation and autonomy and attendance, starting from the existences gained by the exits, of that program. This way, the research will be qualitative, looking for understanding starting from their documents, the existence of those values

I propose with this paper a reflection on the experiences contained in the creation of the body- in-art (FERRACINI, 2006a, b) that originated the show Rosmaninhos... This process was developed within the coletivo UZUME teatro from João Pessoa PB, through recreations and resignifications of the corporeity and physicality contained in the steps, loas, aboios, songs and choreography observed in the manners that Mestre Zequinha plays in his group of Cavalo Marinho (Sea Horse), resident in the city of Bayeux - PB, and starting from the appropriation of the text Hamlet of William Shakespeare. The body-in-art is understood in this work as a vectorial body that dilates its daily functionality, recognizing a potential learning area capable to generate creative escape lines that destabilize the "subject centered in an individuality and identity" (FOUCAULT apud FERRACINI, 2006b, p.14), being open to the differentiation of itself, indicating the possible existence of an itself-other and of the exchange-in-art space. This process of construction of the body-in-art based on Master Zequinha s ways of playing the Cavalo Marinho was methodically guided by the appropriation of the coletivo UZUME teatro of the stages of Observation, Codification and Theatricalization contained in the technique of corporal mimeses proposed by the LUME Teatro (Campinas - SP). That use resulted in two phases: Active Observation and Composition of the body-in-art. Through the repetition of these aesthetic matrixes of the Cavalo Marinho, the actors discovered actions that when, codified and organized, can configure their body-in-art, which created a vectorial exchange-in-art space to what was found in the Cavalo Marinho party. This search proposed the means of potentiating the actors' work when it comes to a preparation that allowed to dilate the scenic presence and stimulated the production of actions, which culminated in the mounting of the show Rosmaninhos...

Until the early 90s, the simulation of fluid flow in oil reservoir basically used the numerical technique of finite differences. Since then, there was a big development in simulation technology based on streamlines, so that nowadays it is being used in several cases and it can represent the physical mechanisms that influence the fluid flow, such as compressibility, capillarity and gravitational segregation. Streamline-based flow simulation is a tool that can help enough in waterflood project management, because it provides important information not available through traditional simulation of finite differences and shows, in a direct way, the influence between injector well and producer well. This work presents the application of a methodology published in literature for optimizing water injection projects in modeling of a Brazilian Potiguar Basin reservoir that has a large number of wells. This methodology considers changes of injection well rates over time, based on information available through streamline simulation. This methodology reduces injection rates in wells of lower efficiency and increases injection rates in more efficient wells. In the proposed model, the methodology was effective. The optimized alternatives presented higher oil recovery associated with a lower water injection volume. This shows better efficiency and, consequently, reduction in costs. Considering the wide use of the water injection in oil fields, the positive outcome of the modeling is important, because it shows a case study of increasing of oil recovery achieved simply through better distribution of water injection rates

The thesis describes parallel possibilities between the knowledge built in theatre and in Science. The narrative is constructed through a reflexive observation of the process of making a threatical play, specifically O Tempo da Chuva by Grupo Beira de Teatro , in analogy to the process of making a scientific theory, specifically the one described by Werner Heisenberg in his book Physics and Beyond: encounters and conversations . It sets a dialog with authors/actors from various areas of knowledge, such as Edgar Morin, Werner Heisenberg, René Descartes, Paul Feyerabend, Paul Caro, Juremir Machado da Silva, Maria da Conceição de Almeida, Renato Ferracini, among others. It discusses the hypothesis that Science is the process of building and the theatrical process of building a play can also be systematized, likewise science. The thesis defends, as the complexities science may suggest, a method as a strategy. Developed throughout the process, such method could only be verified at the end, when the elements of the setting of atomic physics theories and theatre were correlated. Questions such as: the place of theatre and science in our contemporary society and the political and ethical role of artists and scientists are at the episthemological basis of this narrative which we have started, but it is not even close to a conclusion

This study is concerned with analyzing the letters sent by the devotees tothe religious patriarch, Father Cicero, checking as is the relationship of linguistic exchanges between the pilgrims and the Father Cicero through the issuance of letters; and, between the Church and the pilgrims, through homilies uttered these devotees, focusing on the appeals contained therein, for, then, to define a parameter between the requirements contained in the letters and the religious discourse of the Church workers in the liturgical celebrations in view of social and religious demands of the market in question. Our purposes resided in understanding the causes that lead to the production of the letters by devotees, holding us in prayers of intercession to the Father Cicero. Finally, check and understand how is the process of inter - relationship between the writing of devotee and the clerical discourse, with regard to meeting this demand, noting especially the game force a religious field, based on postulates of Pierre Bourdieu (2008), to conceive the communicative act as linguistic exchanges, surpassing the sign and therefore decipherable speech character as well as the interactive strength of the wording and voice advocated by Paul Zumthor (2010) e Bakhtin (2006). Regarding the composition of the corpus, were determined, as the universe of research, letters of pilgrims, sent to Father Cicero, deposited in his own tomb, as well as in the Church of the Horto (Gethsemane) in Juazeiro do Norte-CE (Brazil); beyond religious sermons intended for pilgrims during the massin pilgrimage time

Body and writing: Lines and between-lines of production of knowledge in the classroom it is an ethnographic research, longitudinal character, based on experience while experienced educator of the Escola Municipal Professor Amadeu Araújo, located in the city of Natal-RN, from which are made reflections about texts written by students who have distorted age/education level, in the process of literacy. Here as initial goal: to discuss the production of students writing as a process body, considering the record of experiences and the impressions they have made during the teaching process. We initially by a conception of phenomenological body, by understanding it in its complexity, a phenomenon that is made from its relationship with the world and with the Other. The records examined were produced between the year 2000 and 2005 involving writings of 106 students, constituting a universe of 136 texts, from which, delimited a corpus of 27 texts. The relevance with respect to the theme and recurrence in which they were detected, were up to elements that allowed a systematization methodology, defining the following units of analysis: Body, written in everyday; body, written and sexuality; body, written and enjoyment poetics; body, writing and other stories. We used the techniques of search, participant observation, based on the actions and interactions body expressed during the experiment and the analysis of documents that consisted of students in the texts and secondary sources, among them, the records of daily class, reports and projects developed, as well as reports of my pedagogical practice, as a researcher inserted in the investigative process. The experience developed, showed a writing school able to express nuances of human complexity, showing that learning is made in the action body, crossed by various forms of language and pointing to the relevance of a pedagogical work able to articulate the dialogue between the written and registrations body of the students, as subjects of learning
