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.

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

Análise dos efeitos adversos dos benefícios concedidos às Microempresas e Empresas de Pequeno Porte (EPP) nas licitações públicas brasileiras

The Micro and Small Enterprises are in a special group of companies it given potential for development, employability, and integration into society. Although in Brazil they have high mortality rates, resulted to creation of the Statute of Micro and Small Enterprise in order to encourage it through tax benefits and advantages in public procurement processes. However, the other side of the debate, the public procurement process is the moment when the Public Sector relates to the Private Sector to materialize works, services and shopping. These procurement processes have itself weaknesses, such as excessive bureaucracy, delays and corruption, leading us to inquire: is a good idea promotes the development of micro and small enterprises through weaknesses procurement process? This discussion using theoretical framework, and an analysis of two case studies where the winners of procurement were two enterprises benefited from the Statute of Micro and Small Enterprises

Sexualidade e gênero: processos emancipatórios na relação entre universidade e comunidade

This article presents and analyzes the configuration of a project of university extension, developed in partnership with public schools, which has as themes sexuality and gender issues. We seek to understand to which extent sexuality and gender issues contributes to the continuity of the trio teaching / research / extension, while acting as promoter of knowledge of emancipation of those envolved (under graduates, faculty and the community). We based our presuppositions on action research, with document analysis and questionnaires responded to by participants in the project during the period 2005 to 2011 as the instrument of data collection. We constituted that formative processes that disrupt the predominant perspectives in the educational processes of a stereotypical, biologizing and heteronormative nature of sexuality and gender issues were favoured. Moreover, the experience of inseparability of teaching/research/extension was favoured, based on the understanding of knowledge as something constructed in and through social relations.

Memória, infância e brincar em escritos de Walter Benjamin: cultura lúdica e processos de formação e prática docente

This text aims to present some ideas of the philosopher Walter Benjamin, one of the most intriguing intellectuals of our time, trying to outline in his work the relationship that the author establishes between childhood playing and ludic culture, more precisely regarding the memory of playing, childhood, culture, history and memory in contemporary society after the twentieth century. Thus, in order to identify reinterpreted experiments, as places, forms of playing and types of toys made out of this paradigm, we were guided by the notes, essays, translations and articles in which Benjamin identified conceptions of childhood and ludic culture. Benjamin's view of childhood is not childish, simplistic or reductive. His works allow us to discuss and justify the need for a more detailed analysis on the phenomenon of development and teaching practice within the everyday schoolchildren. By revisiting the original ideas, and irreverent criticism of Benjamin, thinking education from his account, we hope to contribute with other studies in the field of education, by elucidating the process of development and teaching practice in relation to the ludic childhood culture, specifically regarding childhood and the places of childhood in the contemporary context.

Travestis, escolas e processos de subjetivação

In this paper, we analyze transvestites’ reports regarding their experiences at schools. It is a cartography that focuses on negative and positive aspects which call to consideration difficulties from the operators of the education in dealing with this population. Such cartography clarifies the urgent need for opening to a broaden debate to increase the educational actions in the perspective of the protection of the Sexual and Human Rights with strategies of inclusion and defense of citizenship. In spite of the transvestites’ difficulties in enduring and concluding their studies, it is possible to locate some schools in which the transvestites can be welcomed and respected in consideration to their personal choices. Thus, it clarifies the lines that composes their subjectivation processes.
