O objetivo do presente trabalho foi avaliar a eficiência do tratamento da manipueira de extração de fécula de mandioca, em separado da água de lavagem das raízes, através de biodigestores anaeróbicos de fluxo ascendente, com separação das fases, sem controle de temperatura ou adição de produtos químicos e, avaliar sua adequabilidade, através de suas características físicas e químicas para lançamento em corpo receptor, sistema público coletor de esgotos ou, aplicação em processod e fertirrigação. Depois dos reatores estabilizados, foram realizados ensaios variando a vazão de alimentação com 8,0; 12,0 e 16,0 L/d, correspondentes a um tempo de retenção hidráulica de 8,17; 5,44 e 4,08 dias, respectivamente. Os melhores resultados para redução da carga orgânica foram obtidos com os tempos de retenção hidráulica (TRH) de 8,17 e 5,44 dias com eficiências médias de 89,8% e 80,9%, respectivamente. As características físicas e químicas dos efluentes tratados foram comparadas com os valores estabelecidos na legislação estadual, federal e, com os parâmetros utilizados pelo orgão ambiental fiscalizador. Os resultados obtidos mostraram que o efluente tratado atende parcialmente aos requisitos legais para o lançamento em corpos receptores, devido ao teor elevado de nitrogênio amoniacal. Por outro lado, foram atendidos integralmente os requisitos legais para o lançamento na rede pública coletora de esgotos. O efluente tratado não atendeu às recomendações requeridas pelo orgão ambiental fiscalizador para a sua disposição através do processo de fertirrigação devido aos teores elevados de ferro (Fe) e de fluoretos (F). Considerando os resultados obtidos, concluímos que, devido à simplicidade do sistema utilizado, com a implantação de melhorias como um pós-tratamento, poderiam ser atingidos os parâmetros que atenderiam integralmente a legislação.

One of the oldest segments in operations management, whose models are always subject to development efforts, for academics and productive organizations, is the management of production and work organization. Proposals for strategic management principles that seek to bring production to streamline processes reduce costs and add value, identifying problems with material flow and information while reducing the response time. This is realized through the pursuit of the best actions to achieve goals and targets established in a successful Planning and Production Control. This article aims to identify and implement actions that increase the speed of supply of goods produced in a enterprise cutlery; positively influencing the perception of customers. Such attitudes benefit all actors involved in the network, a fact which is expressed in the production chain. To lay the foundations of research and validate the data obtained, it was a study drawing on action research methodology. The goods produced are sold, mainly to wholesalers. Was proved seven aspects to improve and enhance the competitiveness of the organization, among them the complete design of the network, integrating upstream and downstream actors.

The aim of this paper is to present a historical review of the implementation process of the political pedagogical project (PPP) of Londrina (PR). The study used interviews with some agents who participated in the construction of the PPP (teachers, school, supervisors and employees of the Regional Education Center) and investigated the absorption of proposals from the base (school) for the offices of political power. The results showed that although the democratic discourse has always been present in official documents the construction of the PPP had discrete popular participation and projects, as a rule, incorporated the bureaucratic forms issued by official powers.

Based on systemic-cybernetic-new paradigm vision and social constructionism, the paper is an invitation to reflect on the importance of language in the maintenance and the possibility of changing unequal relational patterns, mainly related to issues of gender. Studies on language and verbal behavior of women and men, besides their representation in the media, are examples to illustrate the need advocated here, to changing patterns of inequality guided by gender differences that influence and are influenced by the culture, conveyed in our social network. This paper is a contribution for the clinical work with families and couples, from the perspective of the current behaviors, based on refrains spread by the media which became popular, since it is based on clinical and nonclinical observations about human relationships and its representation in the media and artistic productions.

A Rede Nacional de Televisão Pública Digital3 (RNTPD), antes prevista para ser implantada por meio de um Operador de Rede Público, passa agora a ser estudada para ser efetivada por meio da malha de fibra óptica da Telebrás (banda larga), empresa que apresentou projeto com possibilidade de redução em 50% dos gastos da implantação da rede. Com a previsão da parceria, a meta da implantação da rede deve atingir cerca 4,3 mil cidades em quatro anos, chegando a aproximadamente 80% dos municípios brasileiros. Por meio de uma pesquisa exploratória, este artigo tem o objetivo de apresentar alguns conceitos de televisão pública discutidos pela sociedade civil organizada e academia para a RNTPD.

This paper shows the modeling and control of a single-phase full-bridge inverter with high-frequency transformer that may be used as part of a two-stage converter with transformerless DC-DC side or as a single-stage converter (simple DC-AC converter) for grid-connected PV applications. The inverter is modeled in order to obtain a small-signal transfer function used to design the P+Resonant current controller. A highfrequency step-up transformer results in reduced voltage switches and better efficiency compared with converters in which the transformer is used on the DC-DC side. Simulations and experimental results with a 200 W prototype are shown. 1

The purpose of this article is to reflect on the movement of professionalization of teaching, emphasizing the importance given to vocational training (initial and continuing) in this context. The research is qualitative in that it sought in the testimonies of eight physical education teachers, the São Paulo public state educacional, to elucidate the reflections from the literature review. It was found that although the social and political discourses glimpse the teacher as the main agent of social transformation, this possibility still presents far for this group, especially in view of the heavy workload and poor remuneration, hindering investment in training. It was concluded that this group is immersed in speeches ambiguous and contradictory processes, characterizing a movement of professionalization and concomitant deprofessionalization in teaching.

Given the objective of the Educational Observatory Program of putting in conjunction the efforts of graduation and basic school in order to improve the quality of the latter, are sought possibilities offered by such an arrangement for teacher education. The assumed action research methodology is designed as a collective rethinking about the social practice in which participants were immersed. It is identified strong correlation among the school/graduation interaction and the nature of the underlying teacher education design. The constitution of research questions accomplished inside the school and the centrality of Small Research Groups in a broad network of interactions were determinants.
