O ator que canta um conto: a manipulação de parâmetros musicais na voz do ator

This research started with an investigation about the theatrical speaking. Through an empirical methodology that analyzed a practical experience of creating a play and bibliographical research, the actress/researcher investigated ways to manipulate musical parameters as tools in the creation process of the actor s voice. The actress/researcher attempted to connect theory and practice, moved by the desire to find a vocal expression in theater that unfolds as living and transforming movement. This dissertation also contains the report of pedagogical experiences, in which the actress/researcher explored strategies to teach the appropriation of musical parameters in the construction of the vocal work of the actor. Considering that speaking in theater is closer to singing than everyday speech, she concluded that the actor may compose music as a music composer does in the elaborating process of building vocal scores. Therefore, she demonstrated that it is of fundamental importance a musical training in the development of the actor.

A religiosidade em pessoa

Le Poète Fernando Pessoa (1888-1935), l un des artistes les plus controversés du XXème siècle, se déclarait comme un chrétien gnostique. Malgré cela, il ne s est aligné sur aucune institution et/ou doctrine établie. Mais, il a eu dans la dimension religieuse sa thématique préférée. La proposition de ce travail est de comprendre la religiosité chez Pessoa par le moyen de la lecture d images suscitées à partir de la lecture de son oeuvre, et ainsi, mettre en évidence dans sa vaste production, des significations poétiques qui peuvent être associées à des signes de religiosité, soit dans son contenu manifeste, soit dans le contenu latent de son oeuvre. Ceci, en comprenant que Pessoa, dans tous ses personnages créés par l intermédiaire de l hétéronymie, a fait usage dans son écriture du langage symbolique des univers religieux les plus distincts pour composer sa propre forme de religiosité. Il apparaît que celle-ci est pluriforme et a peut-être com objectif de contrarier les limites sociales établies pour l exercice de la foi

Frankenstein, o prometeu moderno ciência, literatura e educação

À partir des études de l'anthropologue Bruno Latour, dans lesquelles on montre l'importance de la rhétorique et des stratégies institutionnelles dans la fabrication des vérités scientifiques; des hypothèses concernant la nature ambiguë des sciences dressées par Isabelle Stengers et des idées d'Edgar Morin sur la nécessité de combattre la pensée fragmenteuse et de relier culture scientifique et culture humanistique, la thèse aborde la relation de l'homme avec ses artefacts, le défi des descriptions des phénomènes et de leurs propriétés, du dialogue entre les humains et les plusieures dimensions de la matière, et de la responsabilité qui devrait venir avec tous les progrès scientifiques. Victor Frankenstein, sa créature, Brown-Séquard et la testostérone synthétique, sont des acteurs qui aident à composer le panorama cognitif de la recherche qui étend les limites de la science et du social au collectif de non-humains et revendique une réforme de la pensée et de l'éducation que les inclut

Análise de onda completa de superfície seletiva em freqüência do tipo anteparo duplo

This work presents a theoretical analysis and numerical and experimental results of the scattering characteristics of frequency selective surfaces, using elements of type patch perfectly conductor. The structures are composed of two frequency selective surfaces on isotropic dielectric substrates cascaded, separated by a layer of air. The analysis is performed using the method of equivalent transmission line in combination with the Galerkin method, to determine the transmission and reflection characteristics of the structures analyzed. Specifically, the analysis uses the impedance method, which models the structure by an equivalent circuit, and applies the theory of transmission lines to determine the dyadic Green's function for the cascade structure. This function relates the incident field and surface current densities. These fields are determined algebraically by means of potential incidents and the imposition of the continuity of the fields in the dielectric interfaces. The Galerkin method is applied to the numerical determination of the unknown weight coefficients and hence the unknown densities of surface currents, which are expanded in terms of known basis functions multiplied by these weight coefficients. From the determination of these functions, it becomes possible to obtain numerical scattered fields at the top and bottom of the structures and characteristics of transmission and reflection of these structures. At work, we present numerical and experimental results for the characteristics of transmission and reflection. Comparisons were made with other results presented in literature, and it was observed a good agreement in the cases presented suggestions continuity of the work are presented

Estudo do equilíbrio líquido-vapor do sistema água+etanol+líquido iônico visando a separação do álcool anidro

Anhydrous ethanol is used in chemical, pharmaceutical and fuel industries. However, current processes for obtaining it involve high cost, high energy demand and use of toxic and pollutant solvents. This problem occurs due to the formation of an azeotropic mixture of ethanol + water, which does not allow the complete separation by conventional methods such as simple distillation. As an alternative to currently used processes, this study proposes the use of ionic liquids as solvents in extractive distillation. These are organic salts which are liquids at low temperatures (under 373,15 K). They exhibit characteristics such as low volatility (almost zero/ low vapor ), thermal stability and low corrosiveness, which make them interesting for applications such as catalysts and as entrainers. In this work, experimental data for the vapor pressure of pure ethanol and water in the pressure range of 20 to 101 kPa were obtained as well as for vapor-liquid equilibrium (VLE) of the system ethanol + water at atmospheric pressure; and equilibrium data of ethanol + water + 2-HDEAA (2- hydroxydiethanolamine acetate) at strategic points in the diagram. The device used for these experiments was the Fischer ebulliometer, together with density measurements to determine phase compositions. The experimental data were consistent with literature data and presented thermodynamic consistency, thus the methodology was properly validated. The results were favorable, with the increase of ethanol concentration in the vapor phase, but the increase was not shown to be pronounced. The predictive model COSMO-SAC (COnductor-like Screening MOdels Segment Activity Coefficient) proposed by Lin & Sandler (2002) was studied for calculations to predict vapor-liquid equilibrium of systems ethanol + water + ionic liquids at atmospheric pressure. This is an alternative for predicting phase equilibrium, especially for substances of recent interest, such as ionic liquids. This is so because no experimental data nor any parameters of functional groups (as in the UNIFAC method) are needed

Elaboração e aplicação de uma estratégia de ensino sobre os conceitos de calor e de temperatura

This piece of work has investigated the alternative conceptions shown by students of secondary school, concerned to the concepts of warmth and temperature, aiming the elaboration and application of a learning strategy as of the diagnose risen from the conceptions present in students. The learning strategy was built up by a sequence of activities that involve History of Science and experiments, put in a course that had as a base the proposal of the Group of Redevelopment of Physics Teaching (GREF). We have used as the conductor wire of our research the development of thermo dynamics since the development of the first thermo machines, passing by the Industrial Revolution and the evolution of concepts of warmth and temperature. The learning strategy was applied to a group of second grade of secondary school in a public school in Mossoró (RN). By doing these activities we tried to become the concepts, which are part of thermo dynamics, more meaningful to the students. We have estimated that the application of the strategy has represented some profits to the students of the group, concerning to learning of laws and concepts of thermo dynamics (specifically the concepts of warmth and temperature), as well as what it is referred to the overcoming of its initial conceptions

A coleção mossoroense e a construção dos mitos: Dix-Sept Rosado, o herói imolado

This research comprises a study on the values and ideals attributed to Dix-sept Rosado, by the Coleção Mossoroense journal. Local researchers demonstrate how the Coleção Mossoroense constructs an image of Mossoró, forming in the members of the city an identity with the place, a social cohesion or creating one forms to see and to say about the Mossoró city. The Coleção Mossoroense, through Vingt-un Rosado together with its family, established a form of seeing and identifying of the Mossoró s population with the city, just because it associated and it was, at the same time, a movement at the same time social (civic parties for example), political (the domination of the Rosado s family) and cultural (the books and theatrical parties about the city). The conjunction of the Coleção Mossoroense as and with a social movement, cultural and political was capable to establish a social identity, a subjective constituent . With this background, it was possible to make a study of the image attributed to Dix-sept Rosado, by the Coleção Mossoroense, through an analysis of the inherent discourse in the works by Bakhtin (1989) and Bourdieu (2000), of and on Dix-sept Rosado in the Coleção Mossoroense based on. The image of Dix-sept Rosado was constructed by the Coleção Mossoroense after its death, and the responsible for this was Vingt-un Rosado, which was the chief-editor of the Coleção Mossoroense up to 2006, year of its death. The Coleção Mossoroense built an image of Dix-sept Rosado as an enterprising man, progressive and innovator, of great capacity of leadership and oratory (a conductor of the crowds ), popular and charismatic, an honest and dynamic politician. This image made by the Coleção Mossoroense, although when enhancing in surplus the qualities of Dix-sept Rosado have as objective to transmit an image of a heroic personage, it has some relation with the reality. Dix-sept Rosado was a man identified with its locality. This can resemble a regional nationalism. The attitudes of Dix-sept Rosado must be understood inside of a broader social context, of a time marked by the populist politics. Qualities also appreciated and developed inside of a specific historical context and determined both national and locally. The Coleção Mossoroense enhances the qualities of Dix-sept Rosado so that the current politicians of the Rosado s family can establish a link of continuity in its contemporary political practice

Uma abordagem anotativa para gerência de variabilidade em linhas de processos de software: concepção, implementação e avaliação

Nowadays, the importance of using software processes is already consolidated and is considered fundamental to the success of software development projects. Large and medium software projects demand the definition and continuous improvement of software processes in order to promote the productive development of high-quality software. Customizing and evolving existing software processes to address the variety of scenarios, technologies, culture and scale is a recurrent challenge required by the software industry. It involves the adaptation of software process models for the reality of their projects. Besides, it must also promote the reuse of past experiences in the definition and development of software processes for the new projects. The adequate management and execution of software processes can bring a better quality and productivity to the produced software systems. This work aimed to explore the use and adaptation of consolidated software product lines techniques to promote the management of the variabilities of software process families. In order to achieve this aim: (i) a systematic literature review is conducted to identify and characterize variability management approaches for software processes; (ii) an annotative approach for the variability management of software process lines is proposed and developed; and finally (iii) empirical studies and a controlled experiment assess and compare the proposed annotative approach against a compositional one. One study a comparative qualitative study analyzed the annotative and compositional approaches from different perspectives, such as: modularity, traceability, error detection, granularity, uniformity, adoption, and systematic variability management. Another study a comparative quantitative study has considered internal attributes of the specification of software process lines, such as modularity, size and complexity. Finally, the last study a controlled experiment evaluated the effort to use and the understandability of the investigated approaches when modeling and evolving specifications of software process lines. The studies bring evidences of several benefits of the annotative approach, and the potential of integration with the compositional approach, to assist the variability management of software process lines
