In order to determine the value of immunohistochemical staining methods for the morphologic diagnosis, we studied 949 histologic specimens sent for consultation to the Immunohistochemistry Laboratory of Department of Pathology of the Medical School of Botucatu in the period 1984-1989. All case were submitted to the immunoperoxidase staining with the methods PAP or ABC. Immunohistochemical stains confirmed the original morphologic diagnosis in 468 cases (49.3%); made the definitive diagnosis from a list of differential diagnostic possibilities in 244 cases (25.7%); provided contributory information in 74 cases (7.8%); were non-contributory in 114 cases (12%) and rendered an unsuspected diagnosis in 49 cases (5.2%). In some cases with non-contributory information the differences in methods of fixation might have led to suboptimal preservation of tissue antigens. The immunohistochemical staining may provide important and sometimes essential informations for definitive diagnosis. This technique was particularly useful for differential diagnosis between carcinoma, lymphoma and melanoma.

No presente artigo, conforme o entendimento de que modelos te- óricos subsidiam a compreensão de fenômenos investigativos, objetivou-se elucidar os conceitos da teoria sociológica de Norbert Elias, considerando-se que esta é uma excelente fonte de análise para se compreender o universo do ser professor, apesar de o autor não abordar diretamente questões relacionadas ao campo da educação. A partir do conceito de configuração, é possível dizer que a constituição do ser professor resulta das diferentes configurações nas quais ele está imerso, pois, de acordo com Elias, as pessoas (professores, pais, gestores, ministros, alunos etc.) modelam suas ideias a partir de todas as suas experiências e, essencialmente, das experiências vividas no interior do próprio grupo. É observável que as configurações, formadas por grupos interdependentes de pessoas, e não por indivíduos singulares, apresentam-se cada vez mais ampliadas nos contextos escolares, com funções especializadas e específicas (professores, alunos, diretores, coordenadores, supervisores, secretários etc.), em grupos que se tornam cada vez mais funcionalmente dependentes. As cadeias de interdependência estão mais diferenciadas e, consequentemente, mais opacas e dificilmente controláveis por parte de quaisquer grupos ou indiví- duos. Portanto, uma melhor compreensão será possível quando se estudar empiricamente as configurações que estão em jogo na educação brasileira. Daí se justifica a análise das configurações e das teias de interdependência em que os professores estão envolvidos. Enfim, a aplicação dos modelos de competição abordados por Elias possibilita evidenciar as problemáticas sociológicas do ser professor, tornando-as mais evidentes e facilitando o entendimento do jogo para reorganizá-lo em termos de equilíbrio na teia social.

The aim of this paper is to present the effects of social impacts of Petrobras/Six mining of oil shales over the rural community Dois Irmãos, located at Sao Mateus do Sul city, Paraná state. For making mining areas, PETROBRAS/SIX needs to expropriate areas of its interest. In 2010, for the implementation of the mine Dois Irmão, the last one, 90 families were evicted and they directly suffered the impacts of mining. Of these, 62 families were interviewed in order to investigate the main effects suffered with the expropriation. These results showed that the community had difficulties in upgrading its way of life in new places, experiencing how different types of problems were triggered from the loss of the lands.

The search for a dialogical interpretation on the concept theory is the purpose of this paper. It uses the concept of dialogism, proposed by Bakhtin, which refers to the interaction occurring among the social actors in the process of (re)construction of language. Starting from the analysis of texts on concept theory authored by Dahlberg, Hjorland, Tennis and Tennis and Sutton, the convergent, divergent and complementary aspects related to the concepts advocated by the authors are discussed. The analysis revealed that, although these concepts have been built individually, they are reflections of distinct currents of thought and of the historical moments that have influenced each author's ideas. It can be argued, therefore, that the studied concepts were developed on dialogue with other authors and among themselves.

In the present work, the basic concepts of radiometric, photometric and colorimetric calibration are presented, which were applied to three light-emitting diodes (LEDs) used to compose the different color sensations that the human eye perceives in the visible region of the electromagnetic spectrum. In this sense, an experimental setup comprising a LED drive circuit and a home-made integrating sphere was assembled for the initial radiometric and photometric calibration as well as to obtain a set of intensity and spectral combinations associated to different colorimetric CIE (Commission Internationale de l'Eclairage) coordinates. The reader can, therefore, understand, in a simple manner, the process of color composition inside a color monitor or display picture element (pixel ). © Sociedade Brasileira de Física.
