This paper studies modern houses built in the neighborhoods of Cabo Branco, Tambaú and Manaíra by the seafront in Joao Pessoa, built between 1960 and 1974. We start from the already widespread notion that Brazilian Modern Architecture was inspired by foreign ways, mainly European but also American here recast, adapted, often innovating repertoire and ideas received (Y. BRUAND, 2005; H. SEGAWA, 2002; C. E. COMAS, 2002; C. E. COMAS, 2002; M. M. ACAYABA e S. FICHER, 1982; M. B. C. ARANHA, 2008; F. C. L. LARA, 2001; R. V. ZEIN, 2005; L. E. AMORIM, 1999, C. V. STINCO, 2010). With this look, after a field study, we collected 61 specimens in the collection of the Central Archive of João Pessoa City Hall, in order to identify which reformulations, adaptations or innovations would exist in modern houses built along the coast in João Pessoa. As we try to analyze the houses by what the bibliography had suggested (G. C. ARGAN, 1992; L. CORBUSIER, 2002; C.E.D. e M. ADRIÀ, 2007; K. FRAMPTON, 1997; H. H. HITCHCOCK, 1976; L. BENEVOLO, 2004; R. DE FUSCO, 1992, N . PEVSNER, 2002; M. RAGON, 1986; B. RISEBERO, 1982; E. ROBBINS, 1997; W. J. R. CURTIS, 1982; V. SCULLY, 2003; B. ZEVI, 1984; D. DUNST, 1999; A. COLQUHOUN, 2002; R. WESTON, 2005; A. IÑAKI, 2006; J. PETER, 1994) the starting idea seemed to us not sufficiently developed. So we decided, first, to undertake a literature review comparing speech and image of modern houses most often cited by international and national literature, following a script freely inspired the Vitruvian triad: the functional and spatial (sectorization, guidance, spatiality, movement); constructive aspects (structural elements, modulation, deck, sealing), and aesthetic aspects (composition, apertures, ornaments) (Cap.1), then cast a look under this same route in 61 specimens obtained initially, trying to verify any specificities they would have (Cap.2). Failing to deepen the analysis of all these examples, we chose 10 projects which were redesigned and described in more detail to which we supplement with the aspects of place - location / lot location, access, axiality. (E. C. MAHFUZ, 2002; J. C. MIGUEL, 2000; E. C. CHEREGATI, 2007; M. COTRIM, 2007). (Cap. 3). The documentation and description resulting allowed us to approach some related questions about the canonical transcripts hybridizing, adoptions and any vernacular innovations of modern houses along the coast, We conclude that the appellants and anachronistic elements isolates found in each of the studied bind to the Brazilian Modern Architecture

Sustainability in buildings, while reducing the impact on the environment, contributes to the promotion of social welfare, to increase the health and productivity of occupants. The search for a way of build that meets the aspirations and development of humanity without, however, represent degradation of the environment, has become the great challenge of contemporary architecture. It is considered that the incorporation of principles that provide a sustainable building with careful choices of design solutions contribute to a better economic and thermal performance of the building, as well as functional and psychological comfort to its users. Based on this general understanding, this paper presents an architecture project aimed to health care whose the solutions adopted follow carefully the relevant legislation and sets his sights on the theme of sustainability. The methodology began with studies on the themes of verification service of deaths, sustainability and those application in construction developed through research in academic studies and analysis of architectural projects, using them like reference for the solutions adopted. Within the project analysis was performed a visit to the verification service of deaths in the city of Palmas in Tocantins, subsidizing information that, plus the relevant legislation, led to functional programming and pre-dimensional of the building to be designed. The result of this programming environments were individual records with information from environmental restrictions, space required for the development of activities, desirable flow and sustainability strategies, that can be considered as the first product of relevance of the professional master's degree. Finally we have outlined the basic design architecture of a Verification Service of Death SVO/RN (in portuguese), whose process of projecting defined as a guiding line of work four points: the use of bioclimatic architecture as the main feature projectual, the use of resources would provide minimal harm to the environment, the use of modulation and structure to the building as a form of rationalization and finally the search for solutions that ensure environmental and psychological comfort to users. Importantly to highlight that, besides owning a rare theme in literature that refers to architectural projects, the whole project was drawn up with foundations in projective criteria that contribute to environmental sustainability, with emphasis on thermal performance, energy efficiency and reuse of rainwater

I propose with this paper a reflection on the experiences contained in the creation of the body- in-art (FERRACINI, 2006a, b) that originated the show Rosmaninhos... This process was developed within the coletivo UZUME teatro from João Pessoa PB, through recreations and resignifications of the corporeity and physicality contained in the steps, loas, aboios, songs and choreography observed in the manners that Mestre Zequinha plays in his group of Cavalo Marinho (Sea Horse), resident in the city of Bayeux - PB, and starting from the appropriation of the text Hamlet of William Shakespeare. The body-in-art is understood in this work as a vectorial body that dilates its daily functionality, recognizing a potential learning area capable to generate creative escape lines that destabilize the "subject centered in an individuality and identity" (FOUCAULT apud FERRACINI, 2006b, p.14), being open to the differentiation of itself, indicating the possible existence of an itself-other and of the exchange-in-art space. This process of construction of the body-in-art based on Master Zequinha s ways of playing the Cavalo Marinho was methodically guided by the appropriation of the coletivo UZUME teatro of the stages of Observation, Codification and Theatricalization contained in the technique of corporal mimeses proposed by the LUME Teatro (Campinas - SP). That use resulted in two phases: Active Observation and Composition of the body-in-art. Through the repetition of these aesthetic matrixes of the Cavalo Marinho, the actors discovered actions that when, codified and organized, can configure their body-in-art, which created a vectorial exchange-in-art space to what was found in the Cavalo Marinho party. This search proposed the means of potentiating the actors' work when it comes to a preparation that allowed to dilate the scenic presence and stimulated the production of actions, which culminated in the mounting of the show Rosmaninhos...

Dengue, amongst the virus illnesses one can get by vectorial transmission, is the one that causes more impact in the morbidity and mortality of world s population. The resistance to the insecticides has caused difficulties to control of vector insect (Aedes aegypti) and has stimulated a search for vegetables with larvicidal activity. The biodiversity of Caatinga is barely known and it is potential of use even less. Some plants of this biome are commercialized in free fairs northeast of Brazil, because of its phytotherapics properties. The vegetables in this study had been selected by means of a questionnaire applied between grass salesmen and natives of the Serido region from Rio Grande do Norte state; culicids eggs had been acquired with traps and placed in container with water for the larva birth. Thirty larvae had been used in each group (a group control and five experimental groups), with four repetitions four times. The vegetables had been submitted to the processes of decoction, infusion and maceration in the standard concentration of 100g of the vegetable of study in 1l of H2O and analyzed after ½, 1, 2, 4, 8, 12, 24 and 48 hours for verification of the average lethal dose (LD50) from the groups with thirty larva. The LD50 was analyzed in different concentrations (50g/l, 100g/l, 150g/l, 200g/l e 300g/l) of Aspidosperma pyrifolium Mart. 48 extracts of rind, leaf and stem of the seven vegetal species: Aspidosperma pyrifolium Mart., Mimosa verrucosa Benth, Mimosa hostilis (Mart.) Benth., Myracrodruon urundeuva Allemão, Ximenia americana L, Bumelia sartorum Mart Zizyphus joazeiro Mart, had been analyzed. The extracts proceeding from the three methods were submitted to the freezedrying, to evaluate and to quantify substances extracted in each process. The results had shown that Aspidosperma pyrifolium Mart. and Myracrodruon urundeuva Allemão are the species that are more distinguished as larvicidal after 24 hours of experiment, in all used processes of extraction in the assays. The Zizyphus joazeiro Mart species has not shown larvicidal activity in none of the assays. In relation to the extraction method, the decoction was the most efficient method in the mortality tax of the A. aegypti larvae

In this study, a BCR-ABL expressing human chronic myelogenous leukaemia cell line (K562) was used to investigate the antitumoral potential of a novel lectin (CvL) purified from the marine sponge Cliona varians. CvL inhibited the growth of K562 cells with an IC50 value of 70 g/ml, but was ineffective to normal human peripheral blood lymphocytes in the same range of concentrations tested (180 g/ml). Cell death occurred after 72 h of exposure to the lectin and with sign of apoptosis as analysed by DAPI staining. Investigation of the possible effectors of this process showed that cell death occurred in the presence of Bcl-2 and Bax expression, and involved a caspase-independent pathway. Confocal fluorescence microscopy indicated a major role for the lysosomal protease cathepsin B in mediating cell death. Accordingly, pre-incubation of K562 cells with the cathepsin inhibitor L-trans-epoxysuccinyl-L-leucylamido-(4-guanidino)butane (E-64) abolished the cytotoxic effect of CvL. Furthermore, we found upregulation of tumor necrosis factor receptor 1 (TNFR1) and down-modulation of p65 subunit of nuclear factor kappa B (NFB) expression in CvL-treated cells. These effects were accompanied by increased levels of p21 and downmodulation of pRb, suggesting that CvL is capable of cell cycle arrest. Collectively, these findings suggest that cathepsin B acts as death mediator in CvL-induced cytotoxicity possibly in a still uncharacterized connection with the membrane death receptor pathway

A caracterização ambiental da microbacia estudada foi realizada com o objetivo de criar um conjunto de planos de informação (PI's), de modo a permitir um conhecimento apropriado do local pela equipe do projeto, o planejamento de atividades de pesquisa e a identificação de áreas de risco. A microbacia do Córrego Espraiado está localizada entre os municípios de Ribeirão Preto e Cravinhos. As informações básicas utilizadas na caracterização ambiental foram: I) conjunto de cartas planialtimétricas, escala 1:10.000 (IGC, 1992); II) mapa de solos, escala 1:25.000 (MIKLOS, 1996); III) imagem de satélite LANDSAT TM 5, passagem 01/09/93, bandas 3, 4 e 5. A partir destas informações foram gerados os planos: limite da microbacia, redes de drenagem e viária, modelo numérico de terreno (MNT), classes de declive, uso da terra (1995) e solos. Outros planos foram gerados a partir do cruzamento dos anteriores: potencial de infiltração e escoamento superficial da água, potencial natural de erosão, perdas de solo e expectativa de erosão. A versão do IDRISI utilizada foi a 4.1 (DOS). Para a entrada de dados vetoriais foi utilizado o TOSCA 2.12. Na geração dos mapas foi utilizado o COREL DRAW 4. Os planos foram exportados do IDRISI para o COREL DRAW no formato TIF. O limite da microbacia foi traçado sobre as cartas planialtimétricas e posteriormente digitalizado. Com este PI foi construída uma máscara, utilizada para extrair as células que não pertenciam à microbacia em vários procedimentos posteriores. As redes de drenagem e viária foram digitalizadas a partir das informações contidas nas cartas planialtimétricas e rasterizadas pelo módulo LINERAS, gerando os PI's correspondentes. As informações de altimetria passaram por processo semelhante ao anterior, porém na rasterização foi também usado o módulo POINTRAS. Posteriormente as informações de altimetria, já rasterizadas foram interpoladas de modo a preencher todas as células (módulo INTERCON), gerando o MNT da microbacia. Para eliminar os defeitos nas bordas da microbacia, foram também digitalizadas algumas informações de altitude fora do limite da microbacia. Finalmente, para excluir os resultados da interpolação, fora da área de interesse, foi utilizada a máscara realizando-se uma multiplicação entre planos, função presente no módulo OVERLAY. As classes de declive foram obtidas após o calculo da declividade por meio de função presente no módulo SURFECE e o MNT, resultando em um PI intermediário com os valores de declividade em cada célula. Então, utilizou-se o módulo RECLASS para agrupar as células em 7 classes. A imagem em "falsa cor" (composição colorida) foi obtida usando-se o módulo COMPOSIT e posteriormente registrada por meio do módulo RESAMPLE. As coordenadas UTM dos pontos de controle foram extraídos das cartas planialtimetricas. O PI-Uso Atual, foi obtido das informações também retiradas das cartas planialtimetricas, análise da imagem de satélite e de visitas ao campo, realizadas no ano de 1995. O arquivo vetorial produzido foi editado no TOSCA e os polígonos gerados, com o uso do módulo CYCLE. Finalmente o arquivo com os polígonos foi rasterizado (POLYRAS). O PI-Solos foi gerado da digitalização do mapa de solos semidetalhado produzido por MIKLOS (1996). Novamente foi utilizado o TOSCA, seguido dos módulos CYCLE e POLYRAS para produzir o arquivo matricial correspondente. O PI-Potencial de infiltração e Escoamento Superficial da Água foi obtido pelo cruzamento das informações de condutividade hidráulica dos solos e da declividade do terreno. Este PI e um passo intermediário de um método proposto para a identificação das áreas de risco de contaminação por agrotóxicos, apresentado em LUIS (1996) e GOMES (1996). Foram também gerados alguns PI's relacionados com o estudo de erosão na microbacia, utilizando a Equação Universal de Perdas de Solo - EUPS. O IDRISI forneceu os recursos necessários aos objetivos do trabalho. As principais deficiências encontradas são a interface homem/máquina e a criação dos polígonos com a TOSCA, onde há necessidade de informar para cada arco digitado os identificadores dos polígonos por ele dividido. Esta operação consome um esforço considerável e está sujeita a freqüentes erros.

A Dengue constitui-se em importante problema de saúde pública, em todo mundo e em especial no Brasil, em que sua prevalência está em elevação. Por ocasião do diagnóstico situacional, observou-se que a elevada prevalência de dengue é o principal problema da ESF Kwait. O objetivo deste trabalho consiste em elaborar um plano de ação com vistas a diminuir o índice vetorial do mosquito Aedes Aegypti e o número de casos de Dengue na área de abrangência da ESF Kwait, Sete Lagoas, MG. O plano de ação foi realizado conforme o Plano Estratégico Situacional (PES). Realizou-se também revisão narrativa da literatura em periódicos indexados na Biblioteca Virtual em Saúde (BVS), na base de dados Scientific Eletronic Library Online (SciELO). Os principais resultados esperados com este estudo são reduzir as prevalências de Dengue no local e melhorar a qualidade de vida da população.
