O artigo trabalha a noção de amizade em Foucault como um modo de vida que se opõe ao processo de normalização empreendido pelo biopoder. Inicia com uma caracterização acerca do Estado Moderno. Logo após, aborda a historicidade dos processos de subjetivação e de como a atitude frente a estes implica estados de maior autonomia ou sujeição. em seguida, aborda a amizade como resistência à normalização, situando-a em relação ao prazer e à sexualidade. Por fim, discute o papel da filosofia no processo de constituição da amizade, particularmente quanto à possibilidade de pensá-la por meio de uma teoria das relações.

The connections in the wood structures are the places with high concentrations of stresses and therefore are more fragile than the rest of the structure. The connections between pieces of wood can be made by metal pins (nails or screws). The compression and embedment strength has significant influence on the calculation of the connections. The main aim of this work was to evaluate the compression and embedment strength in the directions parallel, inclined at 45° and normal to the grain, using standard specimens according to ABNT NBR 7190/1997 standard. The compression and embedment strength were initially evaluated according to ABNT NBR 7190/1997, which admits the deformation of 2‰ as limit of embedment and the ratio between the ultimate strength and the area of application of load in the specimen for the compressive strength. Afterward, the embedment strength was evaluated by the EUROCEDE 5 /1995 European standard, which use the limit of 5 mm of the displacement for the embedment. Specimens of Pinus oocarpa, Cumaru and Pinus taeda were used in tests to calibration of equipment and specimens of Pinus taeda and Eucalipto citriodora were used to compare the results of strength. The results of strength were evaluated based on statistical analysis. The results of compressive strength for the Pinus taeda showed no significant differences in embedment strength in the directions parallel and normal to the grain. For the Eucalipto citriodora only in the direction parallel to grain the compression strength was not significant compared with the embedment strength. For both species, only the parallel compression strength and inclined at 45o to the grain, which were to the grain, which were admitted the strain of 2‰ were not significantly different compared with the compression strength determined according to ABNT NBR 7190/1997. The normal compression strength obtained according to ABNT NBR 7190/1997 and ultimate compression strength not ...

Given the increasing demand for fossil fuels to power the engines of the global economy, and also the slow process of synthesis of oil, it becomes necessary to develop new sources of renewable energy in addition to improve promising sources that already exist, turning them competitive. Based on this, biomass is shown very promising between the most popular energy sources due to its availability, applicability, and above all, the fact of not emitting green house gases when analyzing the whole carbon cycle. In this sense, this work presents, through an environmental, technical and economic analysis, the impact in an aluminum mill of replacing the use of electricity, in one process, by a boiler fueled with biomass from waste process of packaging the finished product with pallets. Thus, besides the reduction of CO2 emissions, financial gains are targeted, since the main goal of the corporations that require such power is to maximize its profits

O município de Rio Claro, localizado na região central do estado de São Paulo, durante o auge da era do café, da imigração tanto estrangeira como regional e da instalação de várias empresas, dentre elas a Companhia Paulista de Estradas de Ferro se urbanizou num acelerado ritmo, assim como tantas outras cidades do Brasil. Como resultado o aglomerado urbano cresceu, necessitando que seu perímetro expandisse para a zona rural, comprometendo tanto o seu patrimônio histórico quanto o cultural. Antigas propriedades datadas do final do século XIX que resistem à ação do tempo e mantém viva a riqueza e a cultura da época dão lugar à cidade. Esse processo é observado no bairro rural do Sobrado, localizado na região norte de Rio Claro, que vem sofrendo diretamente com a expansão urbana através da criação de novos loteamentos residenciais e comerciais. Portanto, o avanço da urbanização tem provocado à degradação e/ou desaparecimento dos fatos históricos e culturais ainda presentes nos bairros rurais do município

In this research, we discuss important aspects related to the scope of the adult female prostitution in a municipality located in the State of São Paulo, Brazil. We rely on the theoretical contributions provided by the Cultural Studies, the Queer Theory and other aspects referenced by gender studies, by sexualities and other subjective processes, in parallel with the analysis of the reported life stories of two women linked to the context of commercial sexual practice in the studied city. From the presented informations, we observed multiple stories of women in the process of resistance to some standards of femininity, and come to the conclusion that the economic factor is not always preponderant for the entry/residence in female commercial sex practice, especially today, when relationships tend be established by the confluence of multiple interests.

This article approaches the questions about the sexes, genders, desires and sexual standardization practices, starting from the appearance of new sexual identities that can be classified as queer – travesty, transsexual and transgender people. Still, we problematize how the manners of established forms of subjectivity and the hegemonic institutions marginalize such forms of existences, because of the immense difficulty in the encounter with the stranger, the different and the unusual. With those analyses, we are trying to provide the creation of devices to reduce the intensities of the discrimination, of the stigmatization, of the violence, so frequently lived by the people dissident from the heterosexual gender normative, what was reported about their own lived experiences.

Crop species with the C-4 photosynthetic pathway are more efficient in assimilating N than C-3 plants, which results in different N amounts prone to be washed from its straw by rain water. Such differences may affect N recycling in agricultural systems where these species are grown as cover crops. In this experiment, phytomass production and N leaching from the straw of grasses with different photosynthetic pathways were studied in response to N application. Pearl millet (Pennisetum glaucum) and congo grass (Brachiaria ruziziensis) with the C-4 photosynthetic pathway, and black oat (Arena Strigosa) and triticale (X Triticosecale), with the C-3 photosynthetic pathway, were grown for 47 days. After determining dry matter yields and N and C contents, a 30 mm rainfall was simulated over 8 t ha(-1) of dry matter of each plant residue and the leached amounts of ammonium and nitrate were determined. C-4 grasses responded to higher fertilizer rates, whereas N contents in plant tissue were lower. The amount of N leached from C-4 grass residues was lower, probably because the C/N ratio is higher and N is more tightly bound to organic compounds. When planning a crop rotation system it is important to take into account the difference in N release of different plant residues which may affect N nutrition of the subsequent crop.

A resistência do solo à penetração é relacionada com a textura, compactação e umidade do solo. No presente trabalho se estudou o efeito da interação desses fatores sobre o crescimento de raízes de milho. Materiais de solo com 22, 30, 34, 41 e 48% de argila foram acondicionados em tubos de PVC de 10 cm com 4,3 cm de diâmetro interno, nas densidades globais de 1,07, 1,18, 1,36 e 1,53 g cm-3, em três tensões de água: -0,034, -0,106 e -0,640 MPa. Plântulas de milho foram cultivadas nos tubos por 48 horas. Quando a densidade do solo é baixa, a textura tem papel preponderante no crescimento radicular. Esse efeito é menor à medida que aumenta a densidade global. O aumento da resistência do solo à penetração causa diminuição no comprimento e número de raízes seminais adventícias; a raiz seminal primária mostra menor capacidade de penetração do que as raízes seminais adventícias. Resistências do solo à penetração da ordem de 1,3 MPa reduzem à metade o crescimento das raízes seminais adventícias do milho.
