Levantamento bibliográfico sobre o método SODIS de desinformação solar da água

Frente ao desafio de prover água de melhor qualidade para o uso humano a um custo acessível e de simples execução, muitos métodos tem sido desenvolvidos e estudados. Uma metodologia que tem se destacado atualmente, é o método SODIS, sigla em inglês que significa, desinfecção da água por meio da luz solar. Essa metodologia tem como princípio a inativação de uma variada gama de microrganismos patogênicos a partir da ação dos raios solares. Essa metodologia consiste em submeter garrafas de água a um banho de luz solar por algumas horas. Para a realização do método SODIS pode-se utilizar garrafas PET (politereftalato de etileno), sendo que sua execução é simples e rápida além de possuir mínimos riscos envolvidos. A fim de comprovar a eficácia desse método, muitos estudos tem investigado os mecanismos e fatores importantes envolvidos no processo de inativação. Da compreensão desses mecanismos e fatores críticos, preconizou-se ações que visam garantir e maximizar a eficiência do método em variadas situações e condições climáticas sem que o método se torne complexo ou oneroso. O método SODIS se mostrou eficaz na inativação de várias espécies de fungos, vírus, bactérias e até protozoários. Estudos de campo revelaram a sua eficácia prática, ocasionando uma diminuição expressiva nas ocorrências referentes a quadros de diarréia e diarréia severa nas populações estudadas

Sistema de iluminação inteligente através de redes de sensores wireless

The objective of this project is to collaborate with the society, working on a subject that is directly linked to issues of sustainability and environmental preservation. For this, a survey is being developed in order to make possible the creation of an intelligent mechanism, with the use of wireless solutions for the control of energy consumption in order to meet the needs of quality of life and reduce the average consumption of electrical energy. An intelligent lighting system can be explained simply, as an interconnected network of lamps in order to meet needs such as light intensity, the location of it, the moment will turn on or turn off the lights, among other possibilities. This network of lamps is controlled by algorithms implemented using microcontrollers, which may or may not have changed its characteristics. This can be automatic (pre-programmed by the administrator) or manual (controlled via a remote control, phones, etc.), and will depend upon the manager himself and also the characteristics imposed on the project. However, it is important to note that after the search is complete, decisions will be consistent with the Brazilian reality, ie, this system can only be feasible if it has all the characteristics described above, but with an affordable price so that people can acquire it

Qualidade microbiológica de lanches e salgados comercializados em Botucatu, SP

A entrada das mulheres no mercado de trabalho, a dificuldade de locomoção do local de trabalho até a residência, a falta de tempo para o preparo das refeições e o preço mais acessível fez com que a escolha por lanches e refeições rápidas tenha crescido muito, nos últimos anos. Entretanto, esses alimentos estão sujeitos a contaminação desde seu preparo até o momento do consumo, além da manutenção em temperaturas inadequadas. Assim, o objetivo do trabalho foi avaliar microbiológica lanches e salgados comercializados em lanchonetes, “lojas de conveniência” e trailers das principais áreas da cidade de Botucatu, deacordo com os padrões estabelecidos pela ANVISA (RDC N º 12, 2001). As análises foram realizadas de acordo com o Compendium (APHA, 2001). Foram analisadas 122 amostras de salgados de carne, coxinhas, risoles de queijo, camarão e palmito, enrolado de salsicha além de salgado de frios e sanduíches, das quais 17 (13,9%) excederam aos limites microbiológicos. Excesso de coliformes termotolerantes foram encontrados 2 coxinhas, 2 risoles de palmito e 6 salgados de carne, no total de 10 amostras (8,2%). A presença Salmonella spp. foi detectada em duas amostras (1,6%) e clostrídios sulfito redutores apresentaram concentrações acima dos limites em somente uma (0,8%) amostra de salgado de carne. Não foram encontradas amostras com excesso de Bacillus cereus. Staphyloccocus aureus foi observado em valores acima dos permitidos em 8 amostras (6,6%) (5 coxinhas, 2 risoles de frios e 1 salgado). A partir das amostras analisadas, os resultados obtidos indicam que a maioria dos salgados estava dentro dos limites microbiológicos estabelecidos pela ANVISA (2001). Entretanto, 9% das amostras apresentaram patógenos, expondo a população a riscos. É necessária maior vigilância das autoridades competentes e, principalmente, conscientização por parte dos vendedores

Dosimetria ambiental do gás 222Rn: um exemplo de estudo das águas da região de Presidente Prudente – SP e considerações sobre abordagem do tema através do Banco Internacional de Objetos Educacionais – BIOE

Over the years, the concern with the detection of the levels of radionuclides in the environment has increased, given that they are carcinogenic to the human respiratory system. Present in the air, waters, soil and building materials, among other substances, radionuclides are unknown by most of the population. In this paper, we present the radioactive gas 222Rn, predominant element among all others and one way of detecting it in an example study of the waters of the Presidente Prudente - SP, through the plastic detector called CR-39. Likewise, we realized the need to approach this issue more broadly in schools and even in higher education, since this field of modern physics and environmental physics usually appears only in master's and doctorate. Thus, we attempted to perform the didactic transposition schooluniversity, through the construction of an object Educational, OE, to be placed on the Bank for International Educational Objects - bioethanol and by developing this contribute to the knowledge and understanding of the importance of monitoring of radioactivity in a way accessible to the population as a whole

Urbanização de favelas: da espontaneidade à cidade formal

O presente Trabalho Final de Graduação analisou projetos de urbanização de favelas em paralelo com algumas urbanizações feitas nos tecido das cidades medievais que também possuem um traçado inicial de origem espontânea. A partir dessa análise, a pesquisa teve como objetivo a busca de experiências técnicas e de gestão, a partir de bases bibliográficas e visitas em campo, nesses locais de diferentes contextos e, a partir disso, discutir soluções urbanísticas que foram bem‐resolvidas ou dificuldades encontradas nas intervenções. A metodologia empregada para a análise baseou‐se na revisão bibliográfica através das bibliotecas da Universidade Estadual Paulista, da Universidade de São Paulo e do Centro de Documentação da Câmara Municipal de Évora, além do acesso a bibliotecas digitais, como a Base Dedalus da Universidade de São Paulo, a Biblioteca Digital da Universidade Federal de Minas Gerais, a BAE da Universidade Estadual de Campinas, a Minerva da Universidade Federal do Rio de Janeiro, a BU da Universidade Federal de Santa Catarina, BIB da Universidade de Évora e a Biblioteca Nacional de Portugal. Os resultados que foram obtidos buscaram responder perguntas como: quais as questões interessantes a se considerar a partir da análise do projeto – técnicas e de gestão? No caso das favelas, quando houve a remoção, isso foi feito por motivos técnicos pertinentes? E a questão da acessibilidade diante de casos de uma ocupação em encostas com acessos perpendiculares às curvas de nível? Como tornar o local acessível a todos? Isso já foi alguma vez pensado e solucionado? Quais as situações que devem ser observadas para se determinar se deverá ter ou não uma realocação das famílias? A partir dessa avaliação buscou‐se criar, ainda que minimamente, subsídios teóricos para novos projetos de urbanização e entender a efetiva importância sociológica na construção do “habitat humano”

Obtenção e caracterização de compósitos via RTM com alta fração de fibras de carbono processados à temperatura ambiente

After confirming the high specific mechanical properties of composite materials by scientific studies conducted over the last decades, one of the challenges of this new class of materials is the ability to achieve mass production at a more affordable cost, which has become indispensable. The Resin Transfer Molding (RTM) is an excellent method for manufacturing composite materials. Despite being a process widely used by international companies in the production of high performance structural composites, only a short time the national aviation industry has shown interest in implementing this type of processing to more complex structures and greater structural responsibility. In aeronautical projects, the reproducibility and the relative low cost of this process, several studies have been performed in Brazil for learning and perfecting this technique. This process is suitable for producing polymer components both simple as complex geometry, and allows to achieve consistent thickness, with high quality finish and without limiting range. Polymeric composite components for the high mechanical stress applications such as aircraft structures, satellites, etc., require a strict control of volume fractions of the composite constituents, beyond the knowledge of their mechanical and thermal properties. Therefore, in this experimental work degree study on the mechanical, thermal and of porosity composites processed by RTM processed characterization was performed. This characterization was performed targeting a possible aerospace application of this composite material. For the production of composites, process equipment (RTM RTM injector Radius 2100cc) was used. The processed carbono/epoxy composites were characterized via flexure tests mechanically and thermally analysis via DMA, DSC and TGA. To determine the volume fraction of fibers, the composite samples were analyzed via matrix digestion (ASTM D3171) ... (Complete abstract click electronic access below)

Gêneros do discurso, ciência e mídia: a divulgação científica em questão

This work’s main purpose is to research how the scientific speech is outlined on the Revista Língua Portuguesa in statements made by linguists. Statements issued in the previously mentioned magazine have been analyzed. In order to achieve the proposal, the research was based on the following questions: how both the scientific and the scientific divulgation speeches are formed in the magazine, and whether the opinion texts written by scholars and researchers in the linguistic field identify themselves with opinion articles, scientific articles or scientific divulgation texts. Those questions were discussed from the theoretical-methodological bakhtinian perspective, taking the notion of dialogism, the human activity sphere, genres of discourse and style as conceptual elements. It has been detected that there is a complexity in the construction of the genres in the magazine, always taking into account the journalistic and scientific spheres of circulation. The analyzed statements presented themselves as a confluence of many genres’ characteristics, showing a point of view, a scientific subject, a researcher-author and a language adjustment to the magazine reader, making it more accessible. The analysis showed that the discussed statements resemble opinion articles, scientific articles, and reviews, besides being scientific divulgation at the same time

The Invisible Blackness of Harryette Mullen's Poetry: Writing, Miscegenation, and What Remains to Be Seen

This essay addresses the poetics of Harryette Mullen, an awarded African-American female poet whose work questions the boundaries that shape the expectations for accessible intelligibility in African-American literature. Mullen’s poems skirt the edges of intelligibility by going beyond the expectations for a visible/intelligible form of language that would embrace the experience of blackness. I argue that writing in Mullen’s poetry works as process of miscegenation by playing on the illegibility of blackness, beyond a visible line of distinction between what is or should be considered part of blackness itself, which engages new forms of reflection on poetry as a politically meaningful tool for rethinking the role of the black (female) poet within the black diaspora.

Mais ou menos negra? Questões de negritude, tradução e a poesia de Harryette Mullen

This paper addresses issues regarding my translation of selected poems by Harryette Mullen, a rising African-American contemporary poet, whose dense poetry works on the black oral tradition, the experimentalism of writing, the (African-American) pop music, in addition to delving into issues such as the representation of (black) female sexuality. One of the complex aspects of her poetry is the notion of miscegenation, conceived as an aesthetic argument and as a constitutive condition of the identity of multiracial Americans. This concept establishes a textuality that questions the accessible intelligibility generally expected from black American poetry, insofar as a mosaic of dissonant voices are brought to light in her text, which makes it difficult to categorize. In Brazil, especially among politically engaged Afro-Brazilians, there has been criticism towards the praise of miscegenation, since the latter has been considered to support of the myth of racial democracy. Building on these aspects, we investigate the extent to which it is a challenge to translate her poetry – based on miscegenation and hybridity as aesthetic constructs – especially when taking into account the discursive locus of readers identified with an Afro-Brazilian aesthetic, particularly critical of miscegenation. From the point of view of translation, we evaluate the extent to which her poetry could be read by the predominant cultural discourse in Brazil, inclined to favor miscegenation as an integral concept of national identity, as a seductively experimental poetry. In view of this, one wonders whether this perspective makes hers poetry “less black” for Afro-Brazilian literary standards.
