Avaliação dos processos de redestilação e purificação com carvão ativado nas qualidades sensoriais e físico-químicas da cachaça

A cachaça é uma bebida exclusivamente brasileira que vem conquistando espaço no mercado dentre as bebidas alcoólicas destiladas. Porém, o Brasil é responsável pelo consumo de 99% do total produzido por ano e apenas 1% é exportado. Isso se deve à falta de padronização na produção e de conhecimento por parte dos produtores, que levam a contaminação por compostos indesejáveis produzindo uma bebida de baixa qualidade, tanto físico-química quanto sensorialmente. Os métodos de redestilação e filtração em carvão ativado vêm sendo alternativas para melhoria da qualidade. Amostras de cachaças foram submetidas a esses métodos e avaliadas quanto à composição química e a qualidade sensorial. As análises químicas de acidez volátil, aldeídos, ésteres, metanol, álcoois superiores e carbamato de etila foram realizadas em triplicatas utilizando cromatografia gasosa. Para a análise sensorial, as amostras foram submetidas ao Teste de Aceitação utilizando escala hedônica híbrida de nove pontos e avaliadas pelo Teste de Kruskal-Wallis. Foi aplicado também o Teste de Ordenação para avaliar a preferência entre as amostras e a Intenção de Compra foi avaliada utilizando-se uma escala de cinco pontos, de certamente não compraria a certamente compraria. A redestilação reduziu os níveis de acidez volátil, cobre e carbamato de etila enquanto a filtração diminuiu as concentrações de aldeídos e ésteres. Os processos de redestilação e filtração em carvão ativado não alteraram a aceitação da bebida, mantendo seu perfil sensorial e melhoraram a composição química.

Padronização de testes para avaliação do estado de mania e potencial anti-maníaco de um agonista do receptor NOP

Bipolar disorder is characterized by mood impairment, alternating between mania/hypomania and depression, and its exact pathophysiology is already unknown. The treatment of bipolar disorder is based on prevention of the manic and depressive episodes using mood stabilizers. Nociceptin/orfanin FQ (N/OFQ) is an endogenous heptadecapeptide which binds as an agonist to NOP receptor, which is a G-coupled inhibitory receptor. N/OFQ and its receptor modulate a lot of functions in the organism, including emotional processes. It is known that the plasmatic concentration of N/OFQ is altered in patients in both phases depressive and manic of bipolar disorder and it is assumed that this system has a role on the etiology of this disorder. Concerning mania, the animal models used in research tend to focus in an unique aspect of the manic behavior, as hyperactivity or agressivity. In the 60’s, the hole board test was proposed, and it consists of an apparatus with holes where a behavior known as head-dippings is measured. High levels of head-dippings are suggestive of neophilia, while low levels can be characteristic of an anxious-like behavior. As the increase of exploratory and goal-directed behavior are characteristics of manic behavior, this test could help in mania research. Thus, this work was organized in 3 steps and aims to: (1) investigate the induction of a manic-like state promoted by ouabain, a Na+/K+-ATPase inhibitor, in the mouse open field test; (2) set up the hole board as a test to measure manic-like behaviors; and (3) investigate the N/OFQ effects in prevention of this kind of behavior on hole board. Male Swiss mice were used in this study, and they take part of only one of the described steps. Depending on the step performed, mice received one or more of the following treatments: (1) ouabain 10-6 , 10-5 , 10-4 , 10-3 or 10-2 M, intracerebroventricular (icv); (2) sodium valproate 300 mg/kg, intraperitoneal (ip); (3) sodium valproate 400 mg/kg, ip; (4) diazepam 1 mg/kg, ip; (5) methylphenidate 10 mg/kg, ip; and (6) N/OFQ 0,1 or 1 nmol, icv. The results suggest that hole board can be used to evaluate a manic state, through analysis of different animal behaviors. However, it was not possible to standard the model of Na+ /K+ -ATPase dysfunction through ouabain administration in mice. Moreover, the data suggest that N/OFQ, at the doses tested, has not affected the methylphenidate-induced mania-like behavior. Taken together, the results point to a new approach of manic research, through the hole board using. However, more studies are necessary in order to verify the role of N/OFQ system on bipolar disorder.

Implementação LEAN: padronização e auditorias numa linha de pintura industrial

O presente relatório centra-se na aplicação de um sistema de padronização numa célula de pintura industrial. Assim, e como a célula estudada não tinha no momento um sistema de padronização implementado, a principal motivação deste trabalho prendeu-se com a obtenção de benefícios que a normalização de boas práticas pode trazer aos processos, principalmente em indústrias extremamente competitivas, como é o caso do setor em que a empresa em estudo se insere. Para sustentar a implementação da padronização na célula de pintura foi primariamente realizado um estudo teórico sobre a metodologia de base: o LEAN, assim como sobre algumas das suas principais ferramentas. Em particular, destaca-se o Standard Work, ou Padronização, e a Auditoria. Fazendo uso deste levantamento bibliográfico e dos recursos presentes na empresa de acolhimento, foi assim gerado e implementado um sistema padronizado na célula de pintura, composto essencialmente por padrões de tarefas e documentação. Estes têm como principal função criar fundações de base fiável e íntegra, servindo de apoio ao controlo da qualidade, resolução de problemas, e implementação de melhorias no futuro industrial da célula visada. De modo complementar, foi também produzido um conjunto de propostas de implementações de novos métodos, incidindo principalmente na melhoria da qualidade de execução das operações de setup.

Interesses da habitação social : políticas e processos no Rio Grande do Norte

En 2003, le gouvernement brésilien (gestion Lula) a initié une nouvelle phase dans son histoire de l habitation, en intensifiant les constructions de logements sociaux au Brésil. Un tel accroissement a eut des répercussions tant en ville comme à la campagne, et fût marqué dans le Rio Grande do Norte, par la production a grande échelle d ensembles d habitations, dans les programmes de Gouvernement. Afin de viabiliser ces transformations, des instruments politiques, financiers et de gestion ont étés articulés conjointement, utilisant la répétition d une typologie d édification, comme modèle, accompagnée de la reproduction d une morphologie dans les constructions de logements sociaux. Afin de comprendre ce processus nous introduisons une recherche urbanistique et socio-économique du problème du logement social au Brésil, en cherchant à mettre en relation les aspects techniques avec les questions historique, professionnelles et culturelles, éléments complémentaires. Notre analyse cherche a identifier comment les politiques de gestion et financement officielles (administrées dans sa grande majorité par la Caisse Économique Fédérale -CEF-), influencent le processus de conception de projets, en provoquant les répétitions de type/morphologiques, déjà citées. Basée sur l observation directe au cour de deux expériences différenciées pour du logement social en milieu rural, au Rio Grande do Norte, nous montrerons aussi certaines limitations et possibilités des acteurs sociaux, face aux agents et politiques officielles pour le logement social au Brésil, proposant des solutions alternatives standardisées qui caractérisent le résultat des projets financées et gérés par la CEF.

Processos naturais de biodegradação do petróleo em reservatórios

Petroleum biodegradation in reservoirs is a process caused by different microorganisms affecting many oil deposits which modifies the oil composition in a quasi-stepwise process starting from n-alkanes and isoprenoids through to diasteranes. This causes oil souring and increased viscosity, sulfur and metal content, having a direct impact on oil production and refining costs.

The final extraction yield without enzyme treatment was higher (24.28%) compared to the enzyme-treated material (19.03%), with an enhanced aglycones anthocyanin ratio as determined by HPLC- DAD and LC-MS with direct infusion.

Classificação e padronização dos tomates cv. Carmem e Débora dentro da CEAGESP - SP

The creation of the Brazilian Program for the Modernization of the Horticulture by the Secretariat of Agriculture and Supplying of the State of São Paulo at CEAGESP, determined the standardization of fruit and vegetables in the follow aspects: degree of coloration, format, calibers, defects and packing. Therefore, the main goal of this research is to correlate the classification given by the Brazilian Program with the one used by the wholesalers at CEAGESP, verifying if the established norms are being fulfilled for cultivar Carmen and Debora (SAKATA SEED). The results showed, that for cultivar Carmem, for the averages of the observed values it does not move away from the norms created by the Program for sizes small and medium. However, for the case of cultivar Debora, the results showed differences between the adopted classifications. The tomatoes were devaluated, because had been commercialized below of the standardization indicated for the Brazilian Program.

FORMAÇÕES DISCURSIVAS E PROCESSOS IDENTIFICATÓRIOS NA AQUISIÇÃO DE LÍNGUAS

This paper discusses theoretical results of the research project Linguistic Identity and Identification: A Study of Functions of Second Language in Enunciating Subject Constitution. Non-cognitive factors that have a crucial incidence in the degree of success and ways of accomplishment of second language acquisition process are focused. A transdisciplinary perspective is adopted, mobilising categories from Discourse Analysis and Psychoanalysis. The most relevant ones are: discursive formation, intradiscourse, interdiscourse, forgetting n° 1, forgetting n° 2 (Pêcheux, 1982), identity, identification (Freud, 1966; Lacan, 1977; Nasio, 1995). Revuz s views (1991) are discussed. Her main claim is that during the process of learning a foreign language, the foundations of psychical structure, and consequently first language, are required. After examining how nomination and predication processes work in first and second languages, components of identity and identification processes are focused on, in an attempt to show how second language acquisition strategies depend on them. It is stated that methodological affairs of language teaching, learner s explicit motivation and the like are subordinated to the comprehension of deeper non-cognitive factors that determine the accomplishment of the second language acquisition process. It is also pointed out that those factors are to be approached, questioning the bipolar biological-social conception of subjectivity in the study of language acquisition and use and including in the analysis symbolic and significant dimensions of the discourse constitution process.
