Seted in the context of the educational actions of Casa Renascer, a non-governmental organization, located in Natal city, which had as its primary purpose the care with children and adolescent girls in vulnerable situations, this research is based on describing and analysis on the topic in the creative process developed by Asmarias Theatre Company from 1993 to 2003, a process that culminated in the assembly of the dramatic text, Mateus e Mateusa, of Qorpo-Santo. In this research is focused on the route of the Theatre Company has done so much theater in its early history (1993), with the practice of reading and dramatic writing in the preparation of didactic material called Primer of Inventions, as in the procedures with theater street and forum theater (1997 to 2000) to the reunion in 2001 of seven teenagers which articulated the last group formation next to the assembly's text Qorpo-Santo (2002- 2003). During the development on this learning, the evolution of the creative process based on institutional theme when asked if one can provide moments of educational experiences through the traditional form of theater, with reference to the issues inherent in the dramatic texts considered classics. The debate on the issue through research and analysis in its descriptions and finds in the interim between his past and present indications that lead to conclusive guises. The methodology, which is guided by research, is based in theatrical archeology (PAVIS, 2005), the evidential paradigm (GINZBURG, 1989) and the second approaches the experiences narrated by Benjamin (1985). We selected documents in formats of written texts, photographic and filmed, and identified in these files, marks and tracks which took us to understand the subject in the creative process of Asmarias Theatre Company during the tests with the dramatic text, Mateus and Mateusa, of Qorpo-Santo. In this theatrical practice, located in the field of the theater pedagogy, it appears that the actions across thematic theater in the Casa Renascer and allowed the formation of critical aesthetic perspective and personal social dimension of the subjects involved. The theme has gained a significant proportion in the theatrical activity as a guiding point of the creative process of Theatre Company, taking in the theatrical art form. In this sense, the creative process with the dramatic and classic texts won the educational dimension to address the issue in the movement of the drama as the focus of individual creation which added to the collective universe of the interactive game

Lima Barreto has built an educational conception of women in his fictional productions despite nuances inciting scholars to debate his writings and label him as misogynist and philogynist. Thus, the objective of this study is to comprehend, through signs present in his literary works, how women used to be educated in early twentieth century to accomplish the historical differences in gender relations. The main reason for this extract is the periodicity of his publications that started in 1900 by means of chronicles in newspapers and ended in 1922 after his death. For this, we identified codes and rules forged in the social processes to be assimilated by children through diverse institutions, aiming to incite the production of behaviors and social practices represented by the existence men and women in an ever changing society. Gender relations are analyzed within a society for their configuration concept by Nobert Elias (1970) as interdependence bonds among individuals. An investigative method proposed by Ginzburg (1989) was the most adequate to conduct the research on the work of Lima Barreto because it enables us to reconstruct the education concept for women. The dramas and novels analyzed point out the construction of categories such as women education, family, love and seduction revealing the engagement of Lima Barreto with the social problems of the period investigated. It was concluded that gender differentiation has come from family education which kept men and women in opposing sides giving them a marriage perspective that, after consummated, would bring frustration to women causing them to adopt confronting practices against domination strategies through celibacy or adultery. This research constitutes a reflection based on determined representations like justice, respect and duties that were the ideas defended by Lima Barreto in his writings, concerning both broader situations in social life and particular gender relations

Tomamos como un fenómeno a ser estudiado en nuestra investigación las prácticas educativas del Lições de Cidadania. O Lições fue creado como un proyecto y más tarde transformado en un Programa de extensión que se centra en la Educación Popular y los Derechos Humanos, forjado en la reflexión - acción - reflexión. Contribuyó a la reorganización de la formación juridica, extensión universitaria y la situación política de la Universidad Federal de Río Grande do Norte. Circunscribiendo nuestro estudio entre los años 2005 y 2013, tuvo como objetivo identificar, analizar y sistematizar los procesos educativos del Lições que tuvieron lugar durante este período en UFRN y en las comunidades que han dialogado con los sujetos de extensión. Nos guiamos durante la investigación en dos preguntas: ¿Cuáles son las bases educativas del Lições de Cidadania? Y, como el Lições de Cidadania hay operado en el mundo? Estas cuestiones sulearam largo de nuestro estudio y nos llevaron a tomar el paradigma Indiciário señalado por Ginzburg, en su obra: Mitos, Emblemas, Signos: Morfología e Historia (1989). Como una estrategia de investigación, se utilizó la entrevista conversacional libre para el diálogo directo con los chicos y chicas que construyeron el Lições de Cidadania, además de recurrir a la extensa documentación de investigación, principalmente a través de correos electrónicos y actas de las reuniones de planificación del Lições. Llamamos a la rueda de la conversación, el concepto de tránsito en Freire, Vivência y Zona de Desarrollo Próximo de Vygotsky y Peregrinación y Itinerancia en Barbosa Jr. y Tavares. Después de la búsqueda para entender las prácticas educativas del Lições a través de la palabra auténtica de las personas y de los documentos, hemos sido capaces de comprender más profundamente la estructura y la acción del Proyecto a lo largo de su existencia, indicando, para nosotros, que, en realidad, fue un Proyecto de extensión que en la promoción de contacto directo de los estudiantes con las comunidades, también promovió cambios significativos en la manera de ser y vivir de los estudiantes

This thesis analyses the poetry of João Lins Caldas (1888-1967), in Brazilian literature context, aiming at describing and understanding the main features of his poetry. Thus, this research presents a corpus to be worked on: the poems in Poeira do céu e outros poemas (2009). Our study is characterized by a biographical, historiographical and critical tendency, by trying to organize the manuscripts of the author and biographical aspects while analyzing his poems. It is showed the relation between Brazilian poetry written by some authors, since the parnasianism and symbolism period until the twentieth century. On the one hand, our analysis is based on the ideas and criticism by Antonio Candido (2006; 2002; 1985), discussing the process of formation of Brazilian literature and the procedure to analyse poetry. It is also based on the concept of poetry and resistance, developed by Alfredo Bosi (2000; 2002), and the notion of Brazilian matter, identified by Roberto Schwarz (1987, 1997, 1999). On the other hand, this work focuses on melancholy under the theoretical ideas of authors such as Aristotle (1998), Walter Benjamin (1984), Jaime Ginzburg (1997) and Moacyr Scliar (2003). This focus on melancholy contributes to a better understanding of one of the main themes found in the poems analysed. By studying the poetry of João Lins Caldas, it was perceived the relevance of melancholy and resistance in his verses. This can be seen in his dissonant language, characterized by the broken syntax in his verses, as well as contradictory images and complex meanings in his poetry. This causes the effect of unfamiliarity on the reader. His poetry is the result of a style that finds its place in the best moment of modern Brazilian poetry and reveals its singularity through the inverted syntax with powerful themes such as love, death, pain, delusion, loss, memory, nature and God. All of them are aspects of Brazilian historicity. Finally, the work of João Lins Caldas is part of a multifaceted poetry

The standard kinetic theory for a nonrelativistic diluted gas is generalized in the spirit of the nonextensive statistic distribution introduced by Tsallis. The new formalism depends on an arbitrary q parameter measuring the degree of nonextensivity. In the limit q = 1, the extensive Maxwell-Boltzmann theory is recovered. Starting from a purely kinetic deduction of the velocity q-distribution function, the Boltzmann H-teorem is generalized for including the possibility of nonextensive out of equilibrium effects. Based on this investigation, it is proved that Tsallis' distribution is the necessary and sufficient condition defining a thermodynamic equilibrium state in the nonextensive context. This result follows naturally from the generalized transport equation and also from the extended H-theorem. Two physical applications of the nonextensive effects have been considered. Closed analytic expressions were obtained for the Doppler broadening of spectral lines from an excited gas, as well as, for the dispersion relations describing the eletrostatic oscillations in a diluted electronic plasma. In the later case, a comparison with the experimental results strongly suggests a Tsallis distribution with the q parameter smaller than unity. A complementary study is related to the thermodynamic behavior of a relativistic imperfect simple fluid. Using nonequilibrium thermodynamics, we show how the basic primary variables, namely: the energy momentum tensor, the particle and entropy fluxes depend on the several dissipative processes present in the fluid. The temperature variation law for this moving imperfect fluid is also obtained, and the Eckart and Landau-Lifshitz formulations are recovered as particular cases

We address the generalization of thermodynamic quantity q-deformed by q-algebra that describes a general algebra for bosons and fermions . The motivation for our study stems from an interest to strengthen our initial ideas, and a possible experimental application. On our journey, we met a generalization of the recently proposed formalism of the q-calculus, which is the application of a generalized sequence described by two parameters deformation positive real independent and q1 and q2, known for Fibonacci oscillators . We apply the wellknown problem of Landau diamagnetism immersed in a space D-dimensional, which still generates good discussions by its nature, and dependence with the number of dimensions D, enables us future extend its application to systems extra-dimensional, such as Modern Cosmology, Particle Physics and String Theory. We compare our results with some experimentally obtained performing major equity. We also use the formalism of the oscillators to Einstein and Debye solid, strengthening the interpretation of the q-deformation acting as a factor of disturbance or impurity in a given system, modifying the properties of the same. Our results show that the insertion of two parameters of disorder, allowed a wider range of adjustment , i.e., enabling change only the desired property, e.g., the thermal conductivity of a same element without the waste essence

The aim of this work is to derive theWard Identity for the low energy effective theory of a fermionic system in the presence of a hyperbolic Fermi surface coupled with a U(1) gauge field in 2+1 dimensions. These identities are important because they establish requirements for the theory to be gauge invariant. We will see that the identity associated Ward Identity (WI) of the model is not preserved at 1-loop order. This feature signalizes the presence of a quantum anomaly. In other words, a classical symmetry is broken dynamically by quantum fluctuations. Furthermore, we are considering that the system is close to a Quantum Phase Transitions and in vicinity of a Quantum Critical Point the fermionic excitations near the Fermi surface, decay through a Landau damping mechanism. All this ingredients need to be take explicitly to account and this leads us to calculate the vertex corrections as well as self energies effects, which in this way lead to one particle propagators which have a non-trivial frequency dependence

The objective of this work is to understand some of the modifications caused for the phenomenon of the westernization in the hinterland of the Capitania do Rio Grande e in the life of the indians populations that inhabited there during the Colonial Period. We break of the quarrel of Serge Gruzinski concerning the westernization, understood while immersed phenomenon in the context of the expansion of the commercial capitalism and that, for the imposition of the culture occidental person to the alteridades of the New World, emprende the conquest of its territories, bodies and souls. The space clipping has covered the hinterland of the Capitania do Rio Grande, specifically the colonial territory of the Freguesia da Gloriosa Senhora Santa Ana do Seridó. The chosen chronological limit for the research corresponds to the Colonial Period and part of the Imperial one. However, the emphasis falls again on the period that it initiates in 1670, year of the oldest concession of would sesmaria known until the moment in the hinterland of the Rio Grande, extending itself until the decade of 1840. Sources of written by hand nature, cartographic printed and compose the used document roll: official correspondence and legislation, petitions of would sesmaria, inventories post-mortem, justifications of debt, registers of parish, maps, action civil court jurisdiction, notes of notary's office, land landmarks. We take the method, analyzed for Carlo Ginzburg, to cross these sources between itself and to detect its implied particularitities and ideas in the space between lineses, but, attributing it status to they of a colonial speech, fruit of the bureaucracy of where it was originated and of the social place of who produced it. We look for to demonstrate, throughout the work, that the phenomenon of the westernization desestruturou the aboriginal societies and its habitat, constructing, over its rubbles, a colonial territory that found in the cartography of the Freguesia de Santa Ana an efficient instrument of control of the space and the population. On the other hand, if the imposition of the culture occidental person exterminou great part of the native population that inhabited the hinterland of the Rio Grande, the remainders of these indians and the mestizos of descending them had survived in diverse ways in the freguesia: in the condition of captives of war or in regimen of servile work, as living or assistants in the farms, populations and village; rambling without route in the fields and the population spots; as mediating agents between the world occidental person and the native, exerting military or civil positions and still appealing to Justice in search of its rights of inheritance. Experiences of slavery, servitude, errância and mediation, but, also of resistance, adaptation, mestization in the Freguesia de Santa Ana

To build an Portuguese America, after discovering at the beginning of XVI century, the Europeans used the physic, politic colonization and also a space ideological domain using write texts, chronicles, and started making a conceive America that was more European than American. One of those chronicles was the Society of Jesus Chronicle written by father Simão de Vasconcelos, a Jesuit. So our object is recognizing in this chronicle the ways that this father had imagined the America. We are looking to answer how the Jesuit use some references to Classic Antiquity (meanly Aristotle and Samuel) because how this action until happen in the Renascence (XVII century) the intellectual production certainly involve renascent topoi. To get this we used some authors that study Intellectual/ Cultural History like Burckhardt e Ginzburg and some authors from Speech Analyses like Certeau and Foucault, to, in the end, can understand how Simão de Vasconcelos created his Brazil

In this study we simulate numerically the Reynolds' experiment for the transition from laminar to turbulent flow in a pipe. We present a discussion of the results from a dynamical systems perspective when a control parameter, the Reynolds number, is increased. The Landau scenario, where the transition is described by the excitation of infinite oscillatory modes within the fluid, is not observed. Instead what happens is best explained by the Ruelle-Takens scenario in terms of strange attractors. The Lyapunov exponent and fractal dimension for the attractor are calculated together with a measure of complex behaviour called the Lempel-Ziv complexity. (C) 2001 Elsevier B.V. B.V.

The teleparallel versions of the Einstein and the Landau-Lifshitz energy-momentum complexes of the gravitational field are obtained. By using these complexes, the total energy of the universe, which includes the energy of both the matter and the gravitational fields, is then obtained. It is shown that in the case of a closed universe, the total energy vanishes independently of the pseudotensor used, as well as of the three dimensionless coupling constants of teleparallel gravity.
