13. Geometria e simetrias do emaranhamento
In the present work we present a geometric method to identify and measure the degree of entanglement of a two-qubit state. It is based on writing a map of the system state, from a non-unitary transformation. By introducing new parameters for such 4X4 matrix, the product of eigenvalues, two by two, acquire the form of squared 4D distances, having a Minkowski

14. Percepções de médicos sobre o papel do pedagogo no trabalho com crianças hospitalizadas: o caso do Hospital das Clínicas da UFBA.
This study aimed to understand the social representations that paediatricians have about the work of the teacher in the hospital environment. The realization of this research was developed through a qualitative approach that was to guide the Theory of Social Representations. The data collection instruments used were participant observation and semistructured

15. Diferenciação automática de matrizes Hessianas / Automatic differentiation of hessian matrices
In the context of nonlinear programming, many algorithms boil down to the application of Newton s method to the system constituted by the first order Lagrangian conditions. The calculation of Hessian matrices is necessary in this class of solvers. Our focus is on the exact calculation, within machine precision, of Hessian matrices through automatic different

16. Família Contemporânea: complexidades e desafios atuais
The present study sought to understand the place that parents take in the process of raising children, as well as their perception about this process. One of the features that are observed contemporarily are the diversity and the complexity of the interpersonal relationships. In this sense, we live in a moment of doubt on what concerns being in the world, wh

17. Distance education and Aberta University of Brazil when the mercantilization of teaching and the precariousness of teaching reach a new height / EducaÃÃo à DistÃncia e Universidade Aberta do Brasil: quando a mercantilizaÃÃo do ensino e a precarizaÃÃo da docÃncia alcanÃam um novo Ãpice?
Taking as reference onto-methodological the Marxist critique of the capitalist system, we will explain the current moment of capitalism, from the contributions of IstuÃn MÃszÃros about what he calls sociometabolic system of the capital. At the structural crisis of this system the production is characterized as destructive being growing the context of the

18. A wavelet-based approach for analyzing industrial stochastic textures with applications
Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced and the manufacturing processes involved. However, it is often difficult to measure objectively the similarity among industrial stochastic

19. Operational Tau approximation for a general class of fractional integro-differential equations
In this work, an extension of the algebraic formulation of the operational Tau method (OTM) for the numerical solution of the linear and nonlinear fractional integro-differential equations (FIDEs) is proposed. The main idea behind the OTM is to convert the fractional differential and integral parts of the desired FIDE to some operational matrices. Then the F

20. Estado e relações internacionais : uma comparação crítica entre Hans Morgenthau e Nicos Poulantzas / State and international relations : a critical comparison between Hans Morgenthau and Nicos Poulantzas
This work aims the analysis of the concept of State and the function of this institution in international relations. It seeks critically compare the concept of the state used by Hans Morgenthau, acclaimed author of the realist theory of international relations, with the marxist theory of the state systematized by Nicos Poulantzas in Power Politic and Social

21. A class of convex preferences without concave representation
Eu demonstro que uma relação de preferências contínua e convexa que tem curvas de indiferença afins não tem representação côncava se existirem pelo menos duas curvas de indiferença não paralelas. Em outras palavras, uma relação de preferências com curvas de indiferença afins que tem representação côncava tem na verdade uma representação l

22. Representatividade adequada nos processos coletivos / Adequacy of representation on class actions
The main goal of this study is the adequacy of representation analysis, to contribute to enlarge the protection of the collective rights, especially because this very important institute is not a principle of the collective suits in Brazil. Transindividual rights have begun to been studied from the time people became aware of their status as individuals livi

After reading the novel, Recordações do escrivão Isaías Caminha, by the writer Lima Barreto, the work tries to discuss its representation made by the press as a scope of power. . In the first chapter the author presents what she considers to be the most important in the fortune critique of the romance since its publication until nowadays. In the next cha
