This research aims at the study of treatment of clothes washing water through biological treatment, for the purpose of evaluating the reduction of phosphorus to make it suitable for a posterior treatment of physical-chemical. For this purpose it was employed a sequencing batch reactor, consisting of aerobic and anaerobic phases. During the project it was verified not only the reduction of phosphorus (removal of 30 to 50%) but also the reduction of BOD, COD, Turbidity and Nitrate (removal of 38 to 36%, 34 to 41%, 72,3 to 75% and 57,8 to 60% respectively), which demonstrates that the proposed treatment can assist advanced treatments of water for its non potable reuse

Kaposi´s sarcoma associated herpesvirus (KSHV) or human herpesvirus 8 (HHV-8) is a gammaherpesvirus essential for the development of all forms of Kaposi´s sarcoma (KS). The KSHV’s life cycle is basically divided into latent and lytic phases, which have distinct viral gene expression profiles. Some important oncogenic products of KSHV are expressed during the lytic phase, including the viral K1 protein. As an effect of interfer-ence with intracellular signaling, K1 expression increases proliferation and survival of KSHV-infected cells. Due to its high level of genetic variability compared to other re-gions of the viral genome, the K1-encoding ORF (ORF-K1) is commonly evaluated for KSHV genotyping. It remains unclear whether different viral genotypes have particular biological effects that might modify the KSHV oncogenicity. The present study aimed to contribute to the establishment of an experimental in vitro model for evaluation of the K1 protein from common KSHV genotypes. Recombinant expression vectors with the ORF-K1 from KSHV genotypes A, B and C were prepared by genetic cloning. The recombi-nant vectors pKSHVOK1 obtained by cloning were sequenced for structural validation. After that, HEK293 cell line was transfected with the recombinant vectors, and proteins were extracted for expression analysis by Western blot technique, for K1 functional vali-dation. Results showed that ORF-K1 vectors containing KSHV ORF-K1 from the A, B and C genotypes were produced and structurally validated by DNA sequencing. The K1 expression at the protein level was also confirmed by immunoblots using an antibody for FLAG detection, an epitope from the vector that binds to K1. Based on presented re-sults, it´s possible to conclude that the recombinant vectors will be able to be used in future studies of K1 protein biological properties from distinct KSHV genotypes

Currently the market requires companies to adapt for they can have the lowest possible cost in their manufacturing, be it a good or service, thus obtaining a greater profit. For this profit the Toyota Production System applies lean manufacturing practices actions with reduced spending, smaller lots and stocks, generated by market demand. The technique allows SMED with few actions, changes and investments that time does not exceed one digit on your total time. This case study shows that only with standardization and use of inexpensive improvements, could reduce setup time on a machine for 70 minutes to time of approximately 48 minutes with little investment, demonstrating the viability of the tool presented

Nos últimos anos, as pesquisas com células-tronco têm despertado um grande interesse nos meios de comunicação, levando a população a encarar esse novo conhecimento científico como sendo um método promissor para a cura de inúmeras doenças até agora, tidas como incuráveis. Deste modo, mostra-se fundamental que o ensino de Biologia se volte para o desenvolvimento de competências que permitam ao aluno entender, discutir, questionar, analisar, adquirir um posicionamento crítico diante das informações postas e fazendo uso dos conhecimentos adquiridos, servir como multiplicadores do conhecimento científico. Este trabalho tem como objetivo central a produção de um material didático contendo informações a respeito das células-tronco, quanto aos tipos, características, classificações, métodos de coleta e as terapias desenvolvidas no Brasil. Informações estas que servem como auxílio para professores de Ciências e Biologia, na compreensão e atualização perante as inovações científicas relacionadas às células-tronco. O capítulo 6 vem como uma sugestão de atividades possíveis a serem desenvolvidas a partir desse tema. Apresenta ainda um CD-ROM contendo uma síntese do assunto proposto a servir como suporte no preparo de aulas didáticas relacionadas ao tema

Considering fragments of the haroldian poem A Máquina do Mundo Repensada, this paper approximates Drummond and Haroldo de Campos. In this poem, the poetic person’s unquietness conducts him to very peculiar displacements: the one that concerns to the end of millennium, marked by the utopia’s collapse, by the subjectivity fragmentation, by the frontiers’ reconfiguration between people and places. Assuming what the drummondian fatigued eyes have seen, the poet Haroldo de Campos will (re)think his world disharmony

Machine translation systems have been increasingly used for translation of large volumes of specialized texts. The efficiency of these systems depends directly on the implementation of strategies for controlling lexical use of source texts as a way to guarantee machine performance and, ultimately, human revision and post-edition work. This paper presents a brief history of application of machine translation, introduces the concept of lexicon and ambiguity and focuses on some of the lexical control strategies presently used, discussing their possible implications for the production and reading of specialized texts.

In this article we aim to discuss the treatment given to religiosity and sacral in the poem A Máquina do Mundo Repensada (AMMR), published in 2000. In spite of the existence of Bible transcriations made by Haroldo de Campos, especially in the last years of his life, we have made an option to discuss this in the poem because in its pages the religiosity and the sacral amalgamate with the poetic, revealing an interesting creative work.

A predição da resposta do tumor a radioterapia e a questão mais importante durante o tratamento de pacientes com câncer. Como consequência, a predição de genes que sejam responsivos a radiação ionizante e uma possibilidade para a melhoria dos resultados clínicos e a otimização das doses as quais os pacientes são submetidos ao longo do tratamento. Juntamente com esses dados, é possível obter respostas sobre os mecanismos de resistência a radiação dos tumores e até mesmo a identificação de biomarcadores responsáveis pela resistência a radiação ionizante que podem ser potenciais para o desenvolvimento de novas drogas visando a proteção de tecidos saudáveis. A determinação experimental dos genes que sejam responsivos à radiação ionizante é algo caro e que demanda muito tempo e trabalho; porém, se utilizarmos uma forma computacional de direcionar os estudos experimentais diretamente aos genes que têm mais potencial para serem responsivos à radiação ionizante, as pesquisas podem ser mais direcionadas e específicas. Para determinar essa característica, construímos, analisamos e determinamos os dados da topologia da rede integrada de interações moleculares entre genes humanos, contendo interações físicas entre proteínas, interações metabólicas e interações de regulação transcricional. Os dados topológicos foram utilizados como atributos de treinamento para o aprendizado de máquina, no qual os genes conhecidamente responsivos à radiação ionizante foram apresentados a um algoritmo de árvore de decisão que gerou modelos de predição com índices de sensibilidade e precisão de 5% e 72%, respectivamente. Os índices de acerto obtidos para os conjuntos de teste foram satisfatórios, retornando 91% dos genes conhecidos como responsiveis à radiação ionizante utilizados para o treinamento da árvore de decisão. Nós aplicamos o modelo de predição na rede integrada e atribuímos probabilidades ...

This study aims to structurally evaluate a support of graphite pastille for the lubrication of railway wheels. The proper lubrication of wheel flanges of the railway extends the life of this component, so it is very important that this occurs lubrication to reduce the costs involved in railway maintenance. To prepar the evaluation structural will be used to International Electrotechnical Comission standard (IEC 61373) establishing which load cases should be applied to this component. The applied loads on the support (accordance with IEC) are random accelerations and accelerations due to shocks, thus simulating the conditions that exist along the route of the train. The structural analyzes are performed by the finite element method, with the aid of the Cosmos software. Thus, it is possible to determine the stresses acting on the support, and so the allowable stresses compared with the standard proposed by the AISC. The stress in the structural analyzes are lower than allowable therefore considered for the configuration presented, unexpected structural problems
