Avaliação dos processos de tratamento do glicerol proveniente da produção do biodiesel

The substitution of diesel by biodiesel meets the current scenario to increase the consumption of alternative energy sources promoting sustainable development of a country. However, the production of biodiesel concurrently generates the formation of glycerine in the process is a by-product. The main application of glycerine is in the food industry, cosmetics, soaps, pharmaceuticals, among others, but these segments are not capable of absorbing the generated volume of glycerine, whereas the total volume of the biodiesel produced about 10% correspond to glycerine. Glycerine obtained from the transesterification reaction (necessary for production of biodiesel) triglycerides and alcohol contains certain impurities such as water, salts, esters, alcohol, and residual oil, which decrease the value. Thus, the purification process or the direct use of glycerine become essential to make it competitive biodiesel production process. This work aims to evaluate the different processes of purification and the use of glycerine obtained as by-product in the production of biodiesel. The research was theoretical, based on technical articles and theses published on this subject, and from these databases was established a summary of the most important processes

ENGA: trajetória, memória e perspectivas

A Geografia brasileira ainda carece de sua história. Nos anos mais recentes, numerosos artigos têm aparecido, tentando recuperar essa falha, mas nota-se, ainda, a falta de um documento mais abrangente, que recupere os momentos fundamentais, os acertos e os erros, os avanços e as crises no progresso do conhecimento geográfico desenvolvido entre nós. E a lacuna se faz sentir, também, em termos de informações precisas sobre pesquisas, eventos, trabalhos publicados e teses defendidas, sem as quais não se pode reconstruir, de forma segura, a trajetória da Geografia brasileira. (DINIZ et al., 1987, p. 3)

Espaço, território e paisagem: uma leitura teóricometodológica da Geografia Agrária brasileira na pós-graduação a partir dos anos 1970

The aim of this study was to propose a reading of theoretical and methodological geography of Brazilian agriculture in Post-Graduate Studies in Geography (PPGE's) from the Southeast, from the 1970s, trying to present a discussion of the analysis categories (space, territory, landscape, region and place) that has been unleashed over the meetings of Agrarian Geography (ENGA's) and in three meetings of the Research Groups of Agrarian Geography (2005, 2006, 2007). So, we started with the hypothesis that the relativization of scientific concepts may impair development of spatial concepts only. To accomplish our objective we carried out a survey of dissertations and theses supported in the period 1970 to 2009, in Post-Graduate in Geography and UFU UFMG (Minas Gerais), UFRJ, UFF and UERJ (Rio de Janeiro) and USP, UNESP / Rio Claro, UNESP / Presidente Prudente (Sao Paulo). The evaluation dealt with the quantitative and drew a profile of Agrarian Geography. Qualitatively, further analysis, crossing information, contextualizing the themes and especially evaluating the theoretical set referenced in the works, an indication of the possible paths followed by this branch of the Brazilian Geography for which it is observed that the references to the categories space and, more specifically the organization of space, was prioritized in the 1980s and the territory as a reference work after 1990.

A metáfora fundamental do discurso de John Dewey

This work aims to identify the rootmetaphor of John Dewey’s philosophical and educational discourse, by means of rhetorical analyses parameters. This methodology is founded in Aristotle and in the works of Chaïm Perelman and other contemporary authors involved in the revision of Aristotelian philosophy. The article examines the essays “The philosophical work of Herbert Spencer” and “The influence of darwinism on philosophy”, published by John Dewey respectively in 1904 e 1909. They were written in the early years of Dewey in Columbia University, which intellectual environment was not dominated by Pragmatism, and for this reason they can be considered seminal in the structuring of the author’s arguments. The analysis reveals that Dewey is favorable to Darwinian evolutionism thesis and opposite to Spencer’s one. This positioning suggests that Dewey’s discourse is bound to the metaphor “undetermined route” because it situates evolution as a process devoid of previously listed purposes at a pre-determined plan, subject only to the relations that are established, so unpredictable, between organisms and the environmental conditions that surround. Analyzing Dewey’s ideas about education, the article concludes that “undetermined route” is the rootmetaphor of Dewey’s discourse, hypothesis that can contribute to discuss Dewey in the context of contemporary philosophy.

Orçamento Participativo (OP) após vinte anos de experiências no Brasil: mais qualidade na gestão orçamentária municipal?

This article consists on an analysis of dissertations and thesis on Participatory Budget (PB) in post-graduation courses in Brazil (from the CAPES data bank), from 2000 to 2009. It also makes the evolution of works explicit, the institutions where they were carried out, and the area in which they were produced. Results show that the Participatory Budget has not been often evaluated, understood and explained in terms of its finance and budget technical dimension, in spite of there are two decades studies have been carried out regarding this method on budget management in Brazil. Finally, the importance of understanding aspects on PB must be taken into consideration when carrying out new studies.

O estudo das práticas de professores alfabetizadores no ensino da leitura e da escrita (1980 a 2005): o mudar é muito difícil

Neste artigo, apresentamos os resultados de um estudo que investigou o que as pesquisas dos Programas de Pós-Graduação em Educação do Estado de São Paulo produzidas entre 1980 e 2005, com foco nas práticas de professores alfabetizadores, dizem a respeito dos procedimentos, práticas e saberes que caracterizam a atuação desses docentes. Primeiramente, fazemos uma breve contextualização da alfabetização. Em seguida, destacamos a análise do corpus (8 teses e 32 dissertações) nos focos temáticos: procedimentos de alfabetização, práticas docentes e saberes docentes. Os dados apresentados neste artigo permitem apontar permanências e indícios de alterações nas práticas dos alfabetizadores e, consequentemente, nas pesquisas sobre essas práticas.

Anísio Teixeira e a psicologia: o diálogo com a psicanálise

This paper analyses the ideas and the work of Anísio Teixeira in the first years of the 1930s, focusing his conceptions concerning the value of Psychoanalysis for Educational Reform in Brazil. Whereas the ideas and practices Teixeira should be understood in the historical context in which they were developed, the work presents the history of the introduction of the psychoanalytic knowledge in the Brazilian Renovator Educational Movement, highlighting the relevance of hygienism in the dissemination of Freud's theses in education. The findings indicate that Teixeira interacted with the concepts of Psychoanalysis through the hygienist movement and the ideas of Arthur Ramos, considering the individual as being linked to the social environment.

Criopreservação de sêmen equino: uma revisão

A utilização do sêmen resfriado na espécie equina é amplamente difundida, no entanto, quando se trata do sêmen congelado existem certos entraves, os quais tornam o emprego desta biotécnica limitado. Porém seu uso está crescendo e com isso pesquisas com meios diluidores e protocolos de congelação têm sido realizados, a fim de se estabelecer um protocolo que seja eficiente para a congelação do sêmen da maioria dos garanhões. Essa revisão sistemática tem como objetivo a análise de estudos que tratam da congelabilidade do sêmen equino, bem como os principais componentes de um meio diluidor, a fim de demonstrar suas funções e fornecer alternativas para a substituição ou associação, principalmente de crioprotetores. Para tanto, foram utilizadas bases de dados com a seguinte estratégia: criopreservação, congelamento, diluentes, crioprotetores, glicerol, leite, sêmen e equino, presentes no título ou resumo. Dentre os artigos encontrados foram selecionados 15 artigos nas línguas portuguesa, espanhola e inglesa, publicados em revistas científicas ou teses de mestrado, doutorado e trabalhos de conclusão de curso. Tais artigos permitiram concluir que não existem protocolos de congelamento definidos para grupos de animais, mas que deve ser observado cada indivíduo, ressaltando sua peculiaridade e estabelecendo o melhor diluente e protocolo

Fragmentos de experiências no campo da Saúde Mental e Atenção Psicossocial

Neste artigo, reflito sobre a minha experiência como psicóloga e docente-supervisora de estágio do curso de Psicologia de uma Universidade pública. Através de fragmentos de registros mnêmicos das produções registradas em relatórios, comunicações e artigos científicos, dissertação de mestrado, teses de doutorado e de livre docente, entre outros, procurei analisar a efetivação das políticas públicas e os desdobramentos na construção de um novo modelo de saúde mental, denominado de Atenção Psicossocial. Observei que atualmente as Políticas Públicas para Saúde Mental, construídas a partir do Movimento da Reforma Psiquiátrica, vêm propiciando mudanças significativas para o cuidado dos usuários. No entanto, o estado atual da assistência em saúde mental, no país, é marcado por muitos problemas e desafios. Entre eles se destaca a necessidade dos novos serviços oferecerem uma atenção integral ao usuário, norteada na interdisciplinariedade, interprofissionalidade e intersetorialidade.

A autoconfrontação e seus usos no campo da linguística aplicada ao estudo do trabalho do professor

The objective of this study was to present the use of selfconfrontation in applied linguistics (AL) research on teachers’ activities. Selfconfrontation was developed by Faïta (1997), and improved by Clot (2006) within the context of Activity Clinics. It is a device that attempts to capture the multiple discourses around an activity and enable its transformation by workers. Thus, a qualitative research approach was employed and documental analysis of theses, dissertations and papers abstracts produced in Brazil (1987 to 2011), available in the electronic site of CAPES, was performed. The results demonstrated that selfconfrontation is used in a fragmented manner in AL studies that examine teachers’ activities, being primarily used for the collection of data, with little emphasis being placed on the transformation of the labor process.

O trabalho como dispositivo de atenção em saúde mental: trajetória histórica e reflexões sobre sua atual utilização

The partnership between Mental Health (MH) and work is present throughout the history of psychiatry. Capitalist society has used and uses the fitness or unfitness for work not only as one of the elements to the definition of "normality", but also as a treatment strategy. In this perspective, one can find a position healing and, more recently, a different proposal put forward by the psychiatric reform that considers also make / produce, the construction of meaning in the work as crucial for subjectivity. This sense is present in therapeutic workshops that seek to value the uniqueness, not to override the differences. The objective of this paper is to reflect on the relationship between Attention in SM / Work. Initially presents three theses, from which this relationship is built historically: 1 - Work as a means of avoiding idleness returning productively to society; 2 - Work as a healing practice, from the prescription, and 3 - Work as a strategy for care and social inclusion. Below, we discuss some questions about therapeutic workshops and income generation in the mental health care as a device for attention and social inclusion.

O dispositivo metodológico e interventivo autoconfrontação e seus usos em pesquisas de educação

This article presents an academic and scientific study about the use of the device methodological and intervening of selfconfrontation in research in post-graduate studies in Education in Brazil. The self-confrontation is a device created by linguist Daniel Faïta and perfected by psychologist Yves Clot. She seeks to capture the multiple discourses and perspectives around a particular craft, integrating researcher and workers to facilitate the installation of a dialectical movement of analysis and production of knowledge about the work, ownership of these knowledge workers and the collective transformation of labor activity. We chose a qualitative approach and the realization of documental analysis of the abstracts of researches that resulted in the production of doctoral theses and dissertations held in Brazil between 1987 and 2011. Were examined studies that had their abstracts gathered and made available by the Coordenadoria de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) on its website. The results show that self-confrontation is used piecemeal studies produced in the area of Education, used primarily to collect data and to give less emphasis to the transformation of the labor process.
