25. Impacts of a relationship model on informational technology governance: an analysis of managerial perceptions in Brazil
The aim of this article is to analyze the impacts, based on the perceptions of managers, of the deployment of a model to govern the relationship between business areas and IT in a large Brazilian financial organization. To undertake the case study of this deployment, the research firstly performed documental analyses of the process and then sent electronic

26. Bond Graph modeling of the human esophagus and analysis considering the interference in the fullness of an individual by reducing mechanical esophageal flow
INTRODUCTION: This paper shows a proposal for the mathematical modeling of the human esophagus using Bond Graph formalism and the interference in the satiation of an individual by way of an Esophageal Flow Controller (EFC). Therefore, it was evaluated that there is a significant change in fall time that affects the process of human satiety when the diameter

27. The forensic accounting and corporate fraud
This study is aimed at analyzing the characteristics of forensic accounting services performed by accounting firms in Brazil, using an exploratory approach. At the end of the study, there is a discourse analysis of a speech made by the CEO of one of the key players in forensic accounting services (Kroll) in Brazil. In order to guide this reflection, we pose

28. Fibras cuánticas para sistemas clásicos: introducción a la cuantificación geométrica
In this article, We shall introduce the formalism of canonical quantization called "geometric quantization". Since this formalism let us understand quantum mechanics as a geometric extension of classical mechanics, we shall identify the insufficiencies of the latter that are resolved by such an extension. We shall show that geometric quantization permits us

29. Un nuevo esquema conceptual para la interpretación de las mezclas impropias en mecánica cuántica
In this article, we analyze the meaning of density matrices within the formalism of quantum mechanics. We discuss the problem of compound systems in the context of quantum logic as well as the interpretation of improper mixtures. Taking into account the development of convex quantum logic, we present an analysis of the formal structure of the theory which we

30. Application of the rigid finite element method to modelling ropes
Two-dimensional motion of a rope fixed at one end is considered. The Rigid Finite Element Method (RFEM) is reviewed and applied to obtain a model of the rope, including its elastic and dissipative properties. Equations of motion are derived without the small displacement assumption, using the Lagrange equations. The resulting model is compared to another one

31. Non-linear dynamics of a hanging rope
Two-dimensional motion of a hanging rope is considered. A multibody system with elastic-dissipative joints is used for modelling of the rope. The mathematical model based on the Lagrange formalism is presented. Results of some numerical simulations are shown for the mechanical system with kinematic excitation. Basic tools are used to qualify dynamics of the

32. Estudo teórico da estrutura eletrônica e da dinâmica induzida por lasers da molécula de HCl
Potential energy and dipole moment curves for the HCl molecule were computed. Calculations were performed at different levels of theory (DFT, MRCI). Spectroscopic properties are reported and compared with experimental data, for validating the theoretical approaches. Interaction of infrared radiation with HCl is simulated using the wave packet formalism. The

33. Proposal of a new approach for BER evaluation of multirate, multiservice OCDMA systems / Proposta de uma nova abordagem para o cálculo da BER de sistemas OCDMA de múltiplas taxas e multiserviços
The continuous evolution of the optical communication technology in the last few years has allowed the growing users demand for higher bandwidth to be satisfactorily attended. This new demand is mainly attributed to the growing popularity of bandwidth-intensive networking applications, such as Internet protocol television (IPTV), high-definition television (

34. Conversa de Bois, by João Guimarães Rosa: a reading in the light of the authors poetics / \"Conversa de bois\", de João Guimarães Rosa: uma leitura à luz poética do próprio autor
O objetivo deste trabalho, num primeiro momento, foi extrair das 65 cartas que João Guimarães Rosa remeteu à sua tradutora para o inglês, Harriet de Onís, durante a tradução de Sagarana, as linhas gerais que configuram sua poética. Um breve panorama da gênese e da recepção deste livro, seguidos pelos comentários às mencionadas cartas, abriu noss

35. Quantum realism and quantum surrealism
In this thesis we explore the question: whats strange about quantum mechanics? This exploration is divided in two parts: in the first, we prove that there is in fact something strange about quantum mechanics, by showing that it is not possible to conciliate quantum theory with various different definitions of what should be a normal theory, that is, a theory

36. THE CONCEPT OF FORMALISM AND MODERN ARCHITECTURE: A CONTRIBUTION FOR A CRITICAL REVIEW OF THE WORK OF OSCAR NIEMEYER / O CONCEITO DE FORMALISMO E ARQUITETURA MODERNA: CONTRIBUIÇÃO PARA UMA REVISÃO CRÍTICA DA OBRA DE OSCAR NIEMEYER
Percebendo uma dificuldade quase generalizada de se desenvolver uma análise crítica da obra do arquiteto Oscar Niemeyer, e verificando que o discurso corrente se consolidou numa polarização entre detratores e enaltecedores, pautados respectivamente na idéia de um formalismo gratuito ou de uma exuberância criativa, buscou-se inicialmente esclarecer as r
