Um estudo sobre a preparação metalográfica da liga de aluminio AA7075-T6

The increasing technological innovation and demand for materials with better properties boosts research into new materials and new alloys. To do so, aluminum alloys are being developed, among them the AA7075-T6, having many applications in aerospace and military industries, machinery and equipment, molds for plastic injection and structures. To study and understand the properties, characteristics and especially the microstructure of the material, the metallographic preparation is essential. This paper presents new methodologies to achieve the metallography of samples of scrap alloy AA7075-T6, with emphasis on methods of polishing. For the five samples, the best results were those with specific grinding, the samples only going down on the sander. For polishing, the most effective method so far has been using the polishing cloth 16.3, of ATM enterprise, solution of diamond 3 μm, solution of diamond 1 μm, and colloidal solution of OP-S. For the etching, the reactive agent used was phosphoric acid (H3PO4) 85% P.A., as 90% in the proportion of distilled water to 10% acid. The best results were obtained in the attacks of 300 and 240 seconds, revealing the grain boundaries in most areas. Methodologies need more studies and more tests, but the results have proved to be satisfactory

O grupo cervejeiro nacional petrópolis na evolução do capitalismo brasileiro: concorrência e expansão territorial

The processes resulting from globalization are backdrop for the work. On the other hand the Regulation Theory is theoretical north that drives research directions. Considering these two basis, we studied the formation of economic groups as a consequence of the processes of concentration and centralization of capital, giving more emphasis on their national character. We see how they went through the restructuring process in the transition from Fordist accumulation regime to a flexible system of accumulation. We 'll discuss the brewery industry and how major industry groups are currently creating a sector overview, ranging from the productive process to the forms of competition among large companies. Specifically we will see the Petrópolis Group this framework and how the company relates to the territory, and what answers we have of this relationship in terms of local development in the territories where the group entered, and territorial changes which have occurred there

Relações conjugais na literatura de Tostói: análise de duas obras

Existem representações sociais diversas sobre padrões definidores de normalidade que direcionam o erotismo humano, incluindo aí concepções sobre casamento e relacionamento conjugal. A literatura pode ser um modo de evidenciar esses padrões, por isso, este estudo qualitativo, tipo documental, teve por objetivo analisar a temática das relações conjugais em duas obras do autor russo Lev Tolstói: “Felicidade Conjugal” e “A Sonata a Kreutzer”. A partir da análise de conteúdo, os resultados discutem as seguintes categorias: 1) A relação conjugal como sinônimo de posse; 2) O desejo sexual como mercadoria, 3) Enamoramento e Amor e 4) Casamento e Fidelidade e 5) Relacionamento e gênero. Nas duas narrativas as dificuldades nos relacionamentos conjugais são apresentadas de modo a explicitar o enamoramento e o cotidiano tendo como pano de fundo as relações de posse entre as pessoas; a crítica evidente diz respeito ao principio de individuação, que tem como base a propriedade privada, inclusive nos relacionamentos amorosos e sexuais. Conclui-se que a análise dessas obras de Tolstói contribui para refletir sobre como os relacionamentos conjugais se configuram também na atualidade; além disso, ressalta-se que a literatura é um instrumento interessante para problematizar e refletir certos padrões de conduta em sexualidade e que poderia ser usada em propostas intencionais de educação sexual.

Parlamento do Mercosul, integração e déficit democrático

Parlamento do Mercosul: mudança ou continuidade?

The parliamentary representation in the Southern Cone integration is the main issue in this article, which analyzes some implications of the institutionalization of Mercosur Parliament (Parlasur). Consolidation and deepening of the integration process are related to the very weakness of congressional action under the Joint Parliamentary Committee and even the Parlasur. The hypothesis is that the creation of the Mercosur Parliament could contribute to the integration process only insofar as it could overcome the limitations experienced by the Joint Parliamentary Commission and go forward in building a democratic and representative body of regional integration.

Considerações sobre a atualidade da formação cultural/educacional: novos desafios para a pesquisa

This paper aims to draw some outlines of what I understand to be background for possible investigations that examine the cultural / educational problems in Brazil from the perspective of Critical Theory. Under the light of these outlines I intend to present two directions of research which are the main objectives of the research project I develop within the Department of Educational Psychology of College of Sciences and Letters of Unesp in Araraquara. In particular, it is necessary to understand the internal deformation that education suffers as a concrete substance of the teaching process in schools, which makes an empirical investigation how the cultural industry’s schemes become present in the “didactic pedagogical scene” necessary. On the other hand, the elucidation of this problem requires a theoretical investigation about the broader process of constitution of today’s subjectivity under the impact of that industry. Both goals set forth herein are intended to provide subsidies to make readings about new educational demands possible in Brazil.

História da ciência no ensino de Física: um estudo sobre o ensino de atração gravitacional desenvolvido com futuros professores

We report here some outcomes of a research related to a didactical experience aiming to integrate the History of Science to the Physics Teaching, taking as background the historical development of the gravitational attraction. The research, of qualitative approach, is a case study and it was carried out in a sample of eleven students belonging to an undergraduate physics program (called licenciatura in Brazil) designed to from High School physics teachers in a São Paulo State Public University. We tried initially to reveal prospective teachers’ conceptions in order to provide a prepare that was used to guide the activities from the reality’s diagnosis. The aim was to promote discussions on the existence and persistence of alternative conceptions, on the historical evolution of the subject gravitational attraction, through readings and debates of texts contemplating recent subjects on the Science Education research, in order to generate dissatisfaction with traditional teaching models. The future High School physics teachers were asked to construct their own teaching proposal, through the development, in real situations, in a High School, of a minicourse based on: debates and synthesis developed in University classroom, the History of the Science and the student’s alternative conceptions. In this paper we will analyze future teachers’ alternative conceptions, the development of the course proposed, and details of the mini-courses taught by the prospective teachers in real situations, among High School students, its coherence and the posture changes observed in them.
