Discutimos as implicações da noção de adaptação que é uma noção chave para a teoria da evolução clássica. Em lugar de obstinar-se em considerar os organismos como coleção de traços adaptados, propomos buscar estudar a evolução por meio de um quadro teórico onde prevalece uma outra ontologia que destaca o fato de que os organismos e as circunstâncias são totalmente integrados. A etapa preliminar necessária para esta reconsideração consiste em passar de uma lógica prescritiva para uma lógica proscritiva. Isto é, da idéia de que tudo que não é permitido, é proibido; à idéia que o que não é proibido, é permitido. Propomos que a idéia de que os sistemas vivos especificam o mundo no qual eles vivem pode modificar nossa maneira de encarar os processos adaptativos.

This work came from a research question, namely authorizing a child to learn, lifted from the care of a child of 09 years in the school service of a private university located in Natal, whose complaint referred to a learning disorder more specifically, not the formalization of reading and writing. To undertake a survey of the Lacanian psychoanalytic - Freudian literature on learning, we find the concept of knowledge as fundamental to the analysis of this issue which led us to investigate the history of its co nstruction in Freud and Lacan, with a view to shed light on their relationship to learn. This is a theoretical type of research with the proposal to revisit the concept of knowledge in the work of Freud and Lacan's teaching, in which case only served as th e trigger point of this work. We found that in both these authors, the concept of knowledge is associated to the unconscious exclusively and can be hinged to learn the way of the desire to know. It concludes that learning is a process that involves the unconscious knowledge. Consequently, learning disorders may be linked to the impossible into play in the know about the desire to find himself alienated the significant of what operates as forbidden to know when not referred only or also of teaching and / or educational aspects. This shows us that the complaints that come to the clinic can illustrate dilemmas experienced by the speaking, related to subjective questions. Deviations from the possibility of learning may indicate in these cases, a manifestation of what is singular and very impossibility of generalization when it comes to subjects. With this, also attest that the relations of the subject with knowledge effect in learning processes.

Considering the social and economic importance that the milk has, the objective of this study was to evaluate the incidence and quantifying antimicrobial residues in the food. The samples were collected in dairy industry of southwestern Paraná state and thus they were able to cover all ten municipalities in the region of Pato Branco. The work focused on the development of appropriate models for the identification and quantification of analytes: tetracycline, sulfamethazine, sulfadimethoxine, chloramphenicol and ampicillin, all antimicrobials with health interest. For the calibration procedure and validation of the models was used the Infrared Spectroscopy Fourier Transform associated with chemometric method based on Partial Least Squares regression (PLS - Partial Least Squares). To prepare a work solution antimicrobials, the five analytes of interest were used in increasing doses, namely tetracycline from 0 to 0.60 ppm, sulfamethazine 0 to 0.12 ppm, sulfadimethoxine 0 to 2.40 ppm chloramphenicol 0 1.20 ppm and ampicillin 0 to 1.80 ppm to perform the work with the interest in multiresidues analysis. The performance of the models constructed was evaluated through the figures of merit: mean square error of calibration and cross-validation, correlation coefficients and offset performance ratio. For the purposes of applicability in this work, it is considered that the models generated for Tetracycline, Sulfadimethoxine and Chloramphenicol were considered viable, with the greatest predictive power and efficiency, then were employed to evaluate the quality of raw milk from the region of Pato Branco . Among the analyzed samples by NIR, 70% were in conformity with sanitary legislation, and 5% of these samples had concentrations below the Maximum Residue permitted, and is also satisfactory. However 30% of the sample set showed unsatisfactory results when evaluating the contamination with antimicrobials residues, which is non conformity related to the presence of antimicrobial unauthorized use or concentrations above the permitted limits. With the development of this work can be said that laboratory tests in the food area, using infrared spectroscopy with multivariate calibration was also good, fast in analysis, reduced costs and with minimum generation of laboratory waste. Thus, the alternative method proposed meets the quality concerns and desired efficiency by industrial sectors and society in general.

Neste trabalho avaliamos os resultados macroeconômicos recentes da economia brasileira por meio de um instrumental analítico baseado em uma extensão geométrica e algébrica do artigo seminal de Kaldor (1971), que levou à criação do quadrado mágico. Essa abordagem permite a comparação do desempenho pré-crise (2007-2008) e durante a crise (2009-2010). Nossa análise levanta algumas dúvidas sobre as medidas de política econômica adotadas na busca por contornar a presente crise e reduzir obstáculos estruturais no processo de desenvolvimento econômico no Brasil. Concluímos que a complexidade da gestão macroeconômica tem sido subestimada. No que tange às estratégias econômicas, nossa abordagem está centrada na controvérsia entre export-led growth vs consumption-led growth. _________________________________________________________________________________ RESUMEN

Resumo: Predição da concentração de baixo risco de diflubenzuron para organismos aquáticos e avaliação da argila e brita na redução da toxicidade. O diflubenzuron é um inseticida que além de ser usado agricultura, tem sido amplamente empregado na piscicultura, apesar do seu uso ser proibido nesta atividade. Este composto não consta na lista da legislação brasileira que estabelece limites máximos permissíveis em corpos de água para a proteção das comunidades aquáticas. No presente trabalho, a partir da toxicidade do diflubenzuron em organismos não-alvo, foi calculada a concentração de risco para somente 5% das espécies (HC5). O valor deste parâmetro foi estimado em aproximadamente 7 x 10-6 mg L-1 . Este baixo valor é devido à extremamente alta toxicidade do diflubenzuron para dafnídeos e à grande variação de sensibilidade entre as espécies testadas. Dois matérias de relativamente baixo custo se mostraram eficientes na remoção da toxicidade do diflubenzuron de soluções contendo este composto. Dentre esses materiais, a argila expandida promoveu a redução em aproximadamente 50% da toxicidade de uma solução contendo diflubenzuron. Os resultados podem contribuir para políticas públicas no Brasil relacionadas ao estabelecimento de limites máximos permissíveis de xenobióticos no compartimento aquático. Também, para a pesquisa de matérias inertes e de baixo custo com potencial de remoção de xenobióticos presentes em efluentes da aquicultura ou da agricultura. Abstract: Diflubenzuron is an insecticide that, besides being used in the agriculture, has been widely used in fish farming. However, its use is prohibited in this activity. Diflubenzuron is not in the list of Brazilian legislation establishing maximum permissible limits in water bodies for the protection of aquatic communities. In this paper, according toxicity data of diflubenzuron in non-target organisms, it was calculated an hazardous concentration for only 5% of the species (HC5) of the aquatic community. This parameter value was estimated to be about 7 x 10 -6 mg L -1 . The low value is due to the extreme high toxicity of diflubenzuron to daphnids and to the large variation in sensitivity among the species tested. Two relatively low cost and inert materials were efficient in removing the diflubenzuron from solutions containing this compound. Among these materials, expanded clay shown to promote reduction of approximately 50% of the toxicity of a solution containing diflubenzuron. The results may contribute to the establishment of public policies in Brazil associated to the definition of maximum permissible limits of xenobiotics in the aquatic compartment. This study is also relevant to the search of low cost and inert materials for xenobiotics removal from aquaculture or agricultural effluents.
