Nelson Mandela has been an example of fighting and going over the adversities since his prison in 1962 until his election to be the president of South Africa in 1994. His effort against the apartheid in South Africa might be compared to a classical hero according to the anthropological view of Eliade (1972), Campbell (1991; 2007) and Propp’s structuralist perspective (1984). His journey toward heroism and his strategies to get the adhesion of the white minority (Afrikaners) to his purposes of joining the races in South Africa will be analyzed in this article with the theoretical support of the Greimasian semiotics, Propp’s studies (1984) and anthropology. The movie Invictus will be the object of analysis as it shows the moment of Mandela’s social-political fight as the president, with the support of the local rugby team in order to have the racial integration in the country and the political support of the white minority.

Introdução: Os processos industriais geram grandes quantidades de resíduos, representando um grande desperdício de matéria prima e causando impactos negativos ao meio ambiente. No caso dos resíduos gerados pelas fábricas de pás eólicas para aerogeradores de Sorocaba-S.P., eles podem ser reaproveitados na incorporação em cimento Portland. O interesse é utilizá-los na construção civil como blocos sem fins estruturais para construção de muros, guias, calçadas, pisos, etc. Os corpos confeccionados devem obedecer às normas técnicas brasileiras e as suas propriedades relativas à resistência, compressão, absorção de água e distribuição espacial dos resíduos nestes corpos devem ser avaliadas. Objetivos: Devido à importância de se conhecer as propriedades dos corpos produzidos com a incorporação de resíduos de pás eólicas, este trabalho faz uma avaliação através de imagens de raios X de sua distribuição espacial para verificar a viabilidade do emprego desta técnica no estudo da incorporação de resíduos para, futuramente, em conjunto com outras pesquisas que estão sendo realizadas, verificar a relação desta distribuição com as propriedades mecânicas dos corpos produzidos. Métodos: Objetivando a incorporação desse resíduo como substituto parcial dos agregados miúdos em argamassa, foram fabricados corpos de prova (CPs) seguindo as normas da ABNT-NBR 5738. Todos os corpos foram desmoldados após 24 horas de sua confecção e imersos em água por 28 dias para a cura. Utilizou-se o traço 3:1, areia e cimento, em relação a massa dos componentes, ou seja, para cada 300 g de areia adicionou-se 100 g de cimento. Na confecção de argamassa com resíduo utilizou-se o mesmo traço, porém com a substituição de parte da areia pelo resíduo. Foram fabricados CPs com 5%, 15%, 50% e 0% de resíduo para que este sirva de referência. Como os corpos possuem um formato cilíndrico, foram obtidas imagens em duas projeções: frontal e superior utilizando um equipamento digital com os seguintes parâmetros: 83 kVp e 16 mAs e, 85 kVp e 30 mAs, respectivamente. Resultados: As imagens mostram que na projeção frontal é possível verificar que a distribuição do resíduo nos corpos é homogênea, o que pode proporcionar uniformidade nos resultados de testes de resistência à compressão que serão realizados futuramente. Porém, na projeção superior ainda será necessário um estudo dos parâmetros que deverão ser utilizados no equipamento de raios X para melhorar a sua qualidade. Além disso, métodos de processamento digital de imagens poderão ser aplicados nas imagens para auxiliar na visualização dos resíduos incorporados. Também pode ser visto nas imagens que a forma utilizada para a incorporação do resíduo resulta na sua distribuição uniforme, compatível com o que se deseja neste tipo de incorporação.

Currently has few studies today concerning the behavior of the ethyl alcohol hydrated combustible in the geological environment, results of eventual spill or leaks in a wide transport chain and distribution. This work discusses the results of an experiment in laboratorial scale, that involves the monitoring of alterations in physical properties a simulate leak of alcohol in a tank with sand saturated in water, during 4920 hours. Are applied electrical resistivity, induced polarization and spontaneous potential geophysical methods. The electric resistivity is clearly correlating to the ethanol degradation pattern. The chargeability demonstrated sensibility to this pattern, while the natural electric potential revealed direct association with the oscillations of groundwater level. The variability of the physical parameters monitoring probable control for ethanol degradation process in environment study.

Diabetes is a chronic disease that currently affects 171 million individuals approximately worldwide, with projection to reach 366 million people in 2030, increasing the prevalence of 2.8% in 2000 to 4.4%. The dyslipidemia is certainly one of the associated metabolic alterations most important, if we consider the main cause of death in Diabetes - the cardiovascular disease (CVD). One of the prevention and help factors in the Diabetes treatment and in the fall of associated complications is the physical exercise, which contributes to a better life quality to the diabetic. The main objective of the work was to evaluate the effect of a mixed physical exercises training program (aerobic/anaerobic with pause-active), including walking exercises, weightlifting and swiss ball, about possible changes in the blood lipid profile of adult individuals type 2 diabetics. The methodology used an experimental model of pre-test and post-test applied to the group. The data were first analyzed in a descriptive way for the normalization and the elaboration of averages and sample diversions. The sample was subdivided in two moments, being one pre and other post then weeks of training. After these procedures, the results of the values of the lipidic profile and glycemia were compared between the pairs pre and post training (test T Student, pair data), non-parametric. With the study, we can conclude that in despite of the low uptake of participants in the search, for reasons already cited, and the great age difference between them, the found results were partially satisfactory, because we achieved significant changes only in the glycemic variables, but we suggest future studies in the molds here proposed.

This experiment report refers to the project named “Sarauzinho”, which is linked to the extension “Workshops of Psychoanalysis and Artistics Gatherings” project. “Sarauzinho” was a partnership between UNESP and CREAS, created with the aim to assist children victims of sexual violence though a playful and artistic method and to implement a psychoanalytic listening of demands that appeared during the working group implementation. At the same time, the parents/responsible person who took the children to the meetings also received psychotherapeutic service at the waiting room, in an operative group format with psychoanalytic listening. The project has happened in 11 sessions (once a week, two hours each), with 4 kids and 4 caregivers participating. The service for the kids was organized in workshop models (open and free) and in little gatherings, with preprogrammed contents (playful and artistic). The initiative was inspired by the “Green houses”, a creation of the French psychoanalyst Françoise Dolto, and by the Museum “Imagens do Inconsciente do Centro Psiquiátrico Pedro II”, in Nise da Silveira, Rio de Janeiro city. This university extension activity has enabled the students to access some of the children’s traumas, as well as to obtain a better understanding of an infantile group psychotherapeutic service, with psychoanalytic listening. Besides, it has provided a playful and artistic environment to listen to the children and enable them to create new meanings of their traumas. For the adult participants, the meetings were moments to talk about their anxieties and to receive new guidance and instructions about their children’s education, especially about sexuality. The results, either related to the children’s meeting, as to the adult’s meeting, were favorable to the continuity of the project.

The land use conservation planning requires knowledge of the soil characteristics, natural susceptibility to erosion and the soil loss limit. In this context, the objectives of this study were to perform a detailed soil survey of Ribeirão das Perobas watershed, located in Santa Cruz do Rio Pardo, São Paulo State and to determine and map the erodibility and soil loss tolerance of the soil classes found in the survey. The following techniques were used to perform the detailed soil survey: photopedology, field sampling, physical analysis, chemical analysis, and morphological description of the soil samples and profiles. The erodibility was determined by the methods described by Denardin (1990) and Mannigel et al. (2002), and the determination of soil loss tolerance followed the methodology of Mannigel et al. (2002). The results of erodibility determined by the methodology of Denardin (1990) were not discrepant and they did not distinguish soils that are known to have different susceptibility to erosion., w\Whereas, using the methodology of Mannigel et al. (2002), very high or very low erodibility values were observed in soils with extreme contents of sand silt or clay. The most influent variable to the soil loss tolerance results was the correction factor for the textural gradient of clay between soil horizons.
