Aplicações recentes de satélites artificiais com finalidades geodinâmicas requerem órbitas determinadas com bastante precisão. Em particular marés terrestres influenciam o potencial terrestre causando perturbações adicionais no movimento de satélites artificiais, as quais tem sido medidas por diversos processos. A atração exercida pela lua e pelo sol sobre a terra produz deslocamentos elásticos em seu interior e uma protuberância em sua superfície. O resultado é uma pequena variação na distribuição da massa na terra, consequentemente no geopotencial. As perturbações nos elementos orbitais de satélites artificiais terrestres devidas a maré terrestre podem ser estudadas a partir das equações de Lagrange, considerando-se um conveniente potencial. Por outro lado, como tem sido feito pelo IERS, as mudanças induzidas pela maré terrestre no geopotencial podem ser convenientemente modeladas como variações nos coeficientes Cnm e Snm do geopotencial. As duas teorias ainda não foram comparados para um mesmo satélite. Neste trabalho são apresentadas e comparadas as variações de longo período e seculares nas perturbações orbitais devidas à maré terrestre, calculadas por um modelo simples, o de Kozai, e pelo modelo do IERS. Resultados preliminares mostram, para os satélites SCD2 e CBERS1, e para a Lua em movimento elíptico e precessionando, as perturbações seculares no argumento do perigeu e na longitude do nodo ascendente.

The accurate identification of the nursing diagnoses and the corresponding measurement of their indicators will depend on the elements in the standardized language systems. To analyze the correspondence between elements of four NANDA-I nursing diagnoses and outcomes suggested by the nursing outcomes classification (NOC) for the resolution of these diagnoses. A methodological study consisting of cross-mapping was performed in the first stage between definitions, defining characteristics (DCs), and related factors (RFs) of impaired oral mucous membrane, impaired tissue integrity, spiritual distress, and delayed surgical recovery and outcome definitions and indicators to measure results of diagnoses resolution and an analysis of its relevance by experts in the second stage. It found partial correspondence between outcome indicators, DCs, RFs, and definitions. The data evidence the relevance of this review for a reliable application of these taxonomies and demonstrated partial correspondence between concepts analyzed. A identificação precisa dos diagnósticos de enfermagem e a medida correspondente dos seus indicadores dependerá dos elementos nos sistemas de linguagem padronizados. Foi analisar a correspondência entre os elementos de quatro NANDA-I diagnósticos de enfermagem e os resultados sugeridos pelo NOC para a resolução destes diagnósticos. MÉTODO: um estudo metodológico que consiste em cross-mapping foi realizado em uma primeira fase entre as definições, características definidoras e fatores relacionados de Mucosa oral prejudicada, Integridade tissular prejudicada, Sofrimento espiritual e Recuperação cirúrgica retardada e as definições dos resultados indicados para a resolução destes diagnósticos; na segunda fase, foi realizada uma análise desta concordância por especialistas. RESULTADOS: correspondência parcial entre as definições dos diagnósticos e dos resultados, características definidoras e fatores relacionados. CONCLUSÃO: Os resultados evidenciam a relevância dessa avaliação para uma aplicação confiável destas taxonomias e demonstrou a correspondência parcial entre os conceitos analisados. © 2016 NANDA International, Inc.

Uso de modelos mecânicos em curso informal de astronomia para deficientes visuais. Resgate de uma experiência

Tavares, E. T., Jr.; Klafke, J. C.

2003-08-01

O presente trabalho propõe-se a resgatar uma experiência que teve lugar no Planetário de São Paulo nos anos 60. Em 1962, o Sr. Acácio, então com 37 anos, deficiente visual desde os 27, passou a assistir às aulas ministradas pelo Prof. Aristóteles Orsini aos integrantes do corpo de servidores do Planetário. O Sr. Acácio era o único deficiente da turma e, embora possuísse conhecimentos básicos e relativamente avançados de matemática, enfrentava dificuldades na compreensão e acompanhamento da exposição, como também em estudos posteriores. Com o intuito de auxiliá-lo na superação desses problemas, o Prof. Orsini solicitou a construção de modelos mecânicos que, através do sentido do tato, permitissem o acompanhamento das aulas e a transposição do modelo para o "constructo" mental. Essa prática mostrou-se tão eficaz que facilitou sobejamente o aprendizado da matéria pelo sujeito. O Sr. Acácio passou a integrar o corpo de professores do Planetário/Escola Municipal de Astrofísica, tendo ficado responsável pelo curso de "Introdução à Astronomia" por vários anos. Além disso, a experiência foi tão bem sucedida que alguns dos modelos tiveram seus elementos constitutivos pintados diferencialmente para serem utilizados em cursos regulares do Planetário, tornando-se parte integrante do conjunto de recursos didáticos da instituição. É pensando nessa eficácia, tanto em seu objetivo original permitir o aprendizado de um deficiente visual quanto no subsidiário recurso didático sistemático da instituição que decidimos resgatar essa experiência. Estribados nela, acreditamos ser extremamente produtivo, em termos educacionais, o aperfeiçoamento dos modelos originais, agora resgatados e restaurados, e a criação de outros que pudessem ser utilizados no ensino dessa ciência a deficientes visuais.

A análise do conteúdo estelar de galáxias próximas através da fotometria das suas estrelas resolvidas nos fornece informações importantes sobre a história de formação estelar e os processos de formação estelar em galáxias, que estão diretamente ligados ao estudo de evolução de galáxias. Quando nenhuma estrela puder ser resolvida o método mais poderoso consiste na análise do conteúdo estelar integrado das galáxias através das suas cores integradas em conjunto com informação espectroscópica que combinados com modelos de síntese evolutiva podem restringir simultaneamente a função de massa inicial (IMF) e a taxa de formação estelar (SFR). Nesse contexto, galáxias do tipo tardio, em particular, irregulares, são relevantes por várias razões: elas são objetos relativamente simples, com alta atividade de formação estelar e são objetos relativamente jovens (geralmente apresentam baixas abundâncias de elementos pesados e grande quantidade de gás). Apresentamos uma análise fotométrica de uma amostra de 7 galáxias do tipo tardio do universo local (NGC 2366, NGC 4395, NGC 4656, NGC 4214, NGC 4236, HOII, IC2574) que foram observadas com uma boa resolução espacial nas bandas B, V e R no telescópio Isaac Newton de 2.5m de Roque de los Muchachos nas Ilhas Canárias, Espanha. A distribuição espacial da população estelar jovem dessas galáxias é discutida sobre os pontos de vista dos íindices de cor integrados e dos seus diagramas cor magnitude, que comparados com isócronas teóricas, nos fornecem informações sobre os eventos de formação estelar, como por exemplo, indicações sobre a idade dos mesmos. As principais conclusões do trabalho podem ser resumidas em: (i) As galáxias irregulares possuem formação estelar recente (FE) espalhada ocorrendo nos últimos 50 Manos; (ii) A formação estelar em galáxias irregulares não é auto-propagante em escalas globais ( > 100 pc) ; (iii) A FE pode ser auto-regulável em escalas espaciais de poucas dezenas de parsec; (iv) As galáxias irregulares sofreram um evento principal de FE há 1010 anos atrás, o que implica que houve um momento na evolução do universo onde a maior parte das estrelas se formaram em galáxias.

The research presented in this article is about the way science teachers from Elementary School think about astronomical elements. Its methodology is based on semi-structured interviews, which were video recorded. The research is centered in a three-dimensional perspective of astronomical Earth, the Sun, the Moon, the planets and the stars, and also the conceptions about sky and Universe. The esults indicate a Universe that contains: Sun, stars, planets and Moon; where the Solar System is a little part of the whole. Sometimes they think that the Solar System is the Universe. The objects are in the sky or in the Universe, which, for many of them, is only the space above the Earth. The flat shape of astronomical objects and the spatial structure of the Universe are striking features. Many of them think that Sun and stars are different: the Sun is a hot object and the stars are cold ones. These results worry us and they certainly indicate how urgent it is to plan Professional Development in Astronomy for teachers, after all the PCN's emphasize that this subject is important to be taught. El objeto de investigación de este artículo es la manera de pensar sobre los elementos de la Astronomía de los profesores de Ciencias en la enseñanza fundamental. La metodología consiste en entrevistas semi-estructuradas, filmadas en video y centradas en la tridimensionalidad de los elementos astronómicos, para posibilitar un mapeamiento de las concepciones sobre las formas y dimensiones de la Tierra, del Sol, de la Luna, de los planetas y de las estrellas, como también de la concepción de cielo y de Universo en su totalidad. Los resultados indican un Universo conteniendo: Sol, estrellas, planetas y Luna, donde el Sistema Solar se ubica como parte. Algunas veces, el Universo es concebido como el propio Sistema Solar. Los objetos están en el cielo o en el Universo, que, para muchos, se restringe al espacio que está arriba de la Tierra. La forma plana de los objetos astronómicos y la estructura espacial del montaje del Universo son características fundamentales. Muchos indican Sol y estrellas como cosas distintas: el Sol es un objeto caliente y las estrellas son frías. Esos resultados nos preocupan y ciertamente señalan una urgencia de programas de formación continuada para profesores en el contenido de astronomía, pues los PCN's (Parámetros Curriculares Nacionales) recomiendan con énfasis la enseñanza de este contenido. O modo de pensar dos professores de Ciências do ensino fundamental sobre os elementos da Astronomia é o objeto de pesquisa presente neste artigo, cuja metodologia consiste em entrevistas semiestruturadas, filmadas em vídeo e centradas numa perspectiva tridimensional dos elementos astronômicos, possibilitando um mapeamento das concepções das formas e das dimensões da Terra, do Sol, da Lua, dos planetas e das estrelas, bem como da concepção de céu e de Universo como um todo. Os resultados indicam um Universo contendo: Sol, estrelas, planetas e Lua, onde o Sistema Solar é parte do todo. Algumas vezes o Universo é concebido como o próprio Sistema Solar. Os objetos estão no céu ou no Universo o qual, para muitos, se restringe ao espaço que está acima da Terra. A forma plana dos objetos astronômicos e a estrutura espacial da montagem do Universo são características marcantes. Muitos indicam Sol e estrelas como coisas diferentes: Sol é um objeto quente e as estrelas são frias. Esses resultados nos preocupam e certamente sinalizam uma urgência de programas de formação continuada para professores no conteúdo de astronomia, uma vez que os PCN's indicam fortemente o ensino desse conteúdo.

A Influência da Escola e da Mídia na Obtenção dos Conhecimentos Astronômicos

O universo em que vivemos possui segredos jamais imaginados pelo homem, fruto da pequena proporção que ocupamos diante de um cosmos infinito. A astronomia funciona como um instrumento que sacia a sede humana em desvendar esses segredos, estudando as galáxias, quasares, pulsares além da existência de todos os elementos que preenchem o espaço cósmico, o vácuo, não mais vazio como se pensou em outros tempos. A mídia explora esse campo de forma mística e também científica. A difusão adequada e dentro dos padrões educacionais vigentes, de conceitos astronômicos, se faz necessária, devido sua presença nos conteúdos escolares, centros de ciência e na mídia, de modo geral. A reforma do Currículo Básico da Escola Pública da maioria dos Estados brasileiros introduziu conceitos astronômicos desde a pré-escola até o Ensino Médio. Num estudo realizado com 1.032 alunos do Ensino Médio de seis escolas estaduais, revelou-se através da aplicação de um questionário que abordava conheciment os básicos em astronomia, como estes foram adquiridos e qual era a infra-estrutura oferecida pela escola: para 66,2% dos entrevistados o professor já fez alguma apresentação a respeito de astronomia. O presente estudo revelou também que 44,5% dos alunos entrevistados adquiriram seus conhecimentos astronômicos na escola, 28,1% através da televisão e 27,4% afirmaram que seus conhecimentos foram obtidos através de outros tipos de mídia (internet, filmes e revistas). Embora o estudo revele claramente que há certo equilíbrio na forma em que os alunos obtiveram seus conhecimentos astronômicos, a mídia ainda explora e muitas vezes desperta o interesse pela astronomia com assuntos que não fazem parte de nosso cotidiano como, por exemplo, o homem na Lua, os projetos espaciais e a primeira viagem de um astronauta brasileiro no espaço. Porém, em certos casos, a mídia pode promover conhecimentos incompletos ou mesmo equivocados sobre os conceitos que envolvam a astronomia, como por exemplo a propagação do som no vácuo observado na maioria dos filmes de f icção científica ou da existência das estações do ano em função da distância da Terra ao Sol, em conformidade com o questionário aplicado.

Characterisation of gas and particle emissions from wildfires =

NASA Astrophysics Data System (ADS)

Vicente, Ana Margarida Proenca

Os incendios florestais sao uma importante fonte de emissao de compostos gasosos e de aerossois. Em Portugal, onde a maioria dos incendios ocorre no norte e centro do pais, os incendios destroem todos os anos milhares de hectares, com importantes perdas em termos economicos, de vidas humanas e qualidade ambiental. As emissoes podem alterar consideravelmente a quimica da atmosfera, degradar a qualidade do ar e alterar o clima. Contudo, a informacao sobre as carateristicas das emissoes dos incendios florestais nos paises do Mediterrâneo e limitada. Tanto a nivel nacional como internacional, existe um interesse crescente na elaboracao de inventarios de emissoes e de regulamentos sobre as emissoes de carbono para a atmosfera. Do ponto de vista atmosferico da monitorizacao atmosferica, os incendios sao considerados um desafio, dada a sua variabilidade temporal e espacial, sendo de esperar um aumento da sua frequencia, dimensao e severidade, e tambem porque as estimativas de emissoes dependem das carateristicas dos biocombustiveis e da fase de combustao. O objetivo deste estudo foi quantificar e caraterizar as emissoes de gases e aerossois de alguns dos mais representativos incendios florestais que ocorreram no centro de Portugal nos veroes de 2009 e de 2010. Efetuou-se a colheita de amostras de gases e de duas fracoes de particulas (PM2.5 e PM2.5-10) nas plumas de fumo em sacos Tedlar e em filtros de quartzo acoplados a um amostrador de elevado volume, respetivamente. Os hidrocarbonetos totais (THC) e oxidos de carbono (CO e CO2) nas amostras gasosas foram analisados em instrumentos automaticos de ionizacao de chama e detetores nao dispersivos de infravermelhos, respetivamente. Para algumas amostras, foram tambem quantificados alguns compostos de carbonilo apos reamostragem do gas dos sacos Tedlar em cartuchos de silica gel revestidos com 2,4-dinitrofenilhidrazina (DNPH), seguida de analise por cromatografia liquida de alta resolucao. Nas particulas, analisou-se o carbono orgânico e elementar (tecnica termo-optica), ioes soluveis em agua (cromatografia ionica) e elementos (espectrometria de massa com plasma acoplado por inducao ou analise instrumental por ativacao com neutroes). A especiacao orgânica foi obtida por cromatografia gasosa acoplada a espectrometria de massa apos extracao com recurso a varios solventes e separacao dos extratos orgânicos em diversas classes de diferentes polaridades atraves do fracionamento com silica gel. Tendo em conta que a estimativa das emissoes dos incendios florestais requer um conhecimento de fatores de emissao apropriados para cada biocombustivel, a base de dados abrangente obtida neste estudo e potencialmente util para atualizar os inventarios de emissoes. Tem vindo a ser observado que a fase de combustao latente sem chama, a qual pode ocorrer simultaneamente com a fase de chama e durar varias horas ou dias, pode contribuir para uma quantidade consideravel de poluentes atmosfericos, pelo que os fatores de emissao correspondentes devem ser considerados no calculo das emissoes globais de incendios florestais. Devido a falta de informacao detalhada sobre perfis quimicos de emissao, a base de dados obtida neste estudo pode tambem ser util para a aplicacao de modelos no recetor no sul da Europa.

This work presents the elaboration of an answer to the question "Is the dark side of the moon ever illuminated by the sun?", in which issues related to the students' conceptions, how they arise, and the core elements that constitute a "good answer" are considered. These issues are initially elaborated from a literature review of the research in the field; then, and also based on this review, a didactic model that involves the relative motions of the Earth - Moon - Sun system is proposed. A description of the application of this model in a learning environment within middle school students is described. This work confirms the students' initial concepts described in the literature; on the other hand, the questions asked by students during the activity provide evidence that meaningful learning, at least to some degree, has occurred. Este trabalho apresenta a elaboração de uma resposta à pergunta "O lado escuro da Lua nunca apanha sol?" na qual são consideradas questões relacionadas às concepções iniciais dos alunos, de onde elas surgem e os elementos centrais que constituem uma "boa resposta". Essas questões são tratadas, inicialmente, a partir de uma revisão da literatura sobre pesquisas na área e, em seguida, também com base nessa revisão, um objeto modelo didático que envolve os movimentos relativos do sistema Terra - Lua - Sol é proposto. Uma descrição detalhada da aplicação deste modelo em um ambiente de aprendizagem com alunos do ensino fundamental é relatada. As concepções iniciais apresentadas na literatura se confirmam e os questionamentos feitos pelos estudantes por ocasião da aplicação do modelo fornecem indícios de que uma aprendizagem significativa, pelo menos em algum grau, ocorreu. El artículo se presenta el desarrollo de una respuesta a la pregunta "¿El lado oscuro de la luna nunca toma sol?", en la que se consideran algunas cuestiones vinculadas que se refieren a las concepciones iniciales de los estudiantes, dónde surgen y los elementos básicos que componen una "respuesta correcta". Estas cuestiones se tratan inicialmente a partir de una revisión bibliográfica de la investigación en el área; seguidamente, y también sobre la base de ésta revisión, se propone un modelo didáctico que ejemplifica los movimientos relativos del sistema Tierra - Luna - Sol. Se describe a continuación una aplicación de este modelo en un entorno de aprendizaje con alumnos del ciclo primario. Los conceptos iniciales presentados en la literatura se confirman y las cuestiones planteadas por los estudiantes durante la implementación del modelo proporcionan evidencia de que se ha producido un aprendizaje significativo, al menos en cierta medida.

Comportamiento del Helio en estrellas químicamente peculiares

NASA Astrophysics Data System (ADS)

Malaroda, S. M.; López García, Z.; Leone, F.; Catalano, F.

Las estrellas químicamente peculiares (CP) se caracterizan por tener deficiencias y sobreabundancias de algunos elementos químicos de hasta 106 veces la abundancia solar. Además presentan variaciones en las líneas espectrales. Se piensa que ello se debe a que los campos magnéticos presentes en este tipo de estrellas son principalmente dipolares, con un eje de simetría diferente del eje de rotación. La distribución de los elementos sobreabundantes y deficientes no es homogénea sobre la superficie estelar y las variaciones observadas serían una consecuencia directa de la rotación estelar. Entre los elementos con abundancia anómala se encuentra el Helio, cuyas líneas tienen intensidades que no son consistentes con una abundancia normal, que no puede ser determinada del modo usual, o sea, considerando una atmósfera con composición solar. Con el fin de determinar la abundancia de este elemento, se inició un estudio de estrellas anómalas de Helio, Hew y He strong. Además se determinarán las abundancias de otros elementos anómalos como ser el Si, Cr, Mg, Mn y Fe. Las mismas se determinan del modo tradicional, o sea: a) medida de los anchos equivalentes de las líneas de los distintos elementos analizados; b) adopción de la temperatura efectiva, gravedad y abundancia del Helio; c) cálculo del modelo de atmósfera d) comparación con las observaciones y reinicio de un proceso iterativo hasta lograr un acuerdo entre todos los parámetros analizados. Las observaciones se llevaron a cabo en el Complejo Astronómico El Leoncito. Se observaron setenta y ocho estrellas anómalas de Helio. En este momento se está procediendo a calcular las abundancias correspondientes a los distintos elementos químicos. Para ello se hace uso de los modelos de Kurucz, ATLAS9. Los cálculos NLTE de las líneas de Helio se llevan a cabo con el programa MULTI y se compararán con los realizados con el programa WIDTH9 de Kurucz (LTE), con el objeto de resaltar la importancia de los efectos NLTE.

Análise cinemática bi-dimensional dos núcleos de NGC 4051 e NGC 4941

Estudos recentes da cinemática da região dentro de 1 kpc do núcleo de galaxias Seyfert próximas usando espectroscopia de fenda longa com alta resolução espacial (~ 100 pc ou melhores) encontraram uma queda na dispersão de velocidades nas regiões centrais dentro de um raio de ~ 300 pc do núcleo. Essa queda vem sendo tentativamente explicada por um cenário evolutivo em que um evento de formação estelar recente cria as estrelas da região central em um disco de dimensões 300 pc. Desde sua criação, tais estrelas não tiveram tempo de "virializar", ou seja, seguir a distribuição radial de dispersões de velocidades determinada pelo campo gavitacional da galáxia e, portanto, a dispersão de velocidades medida nessa região do bojo acaba sendo menor do que a dispersão medida nas vizinhanças. No presente trabalho investigamos a cinemática estelar no núcleo das galáxias Seyfert NGC 4051 e NGC 4941 usando o tripleto do Ca ii (8500 Å) em absorção. Os dados foram obtidos com o IFU GMOS no telescópio Gemini. O elemento de resolução espacial nas galáxias é da ordem de 30 pc. No intervalo espectral coberto pelo espectrografo a linha [S iii] (9068 Å) também é visível, o que permite estudar a cinemática do gás na mesma região. Serão apresentados mapas bi-dimensionais da velocidade e dispersão de velocidades das estrelas e do gás, além de imagens na linha [S iii] que mapeia o gás de alta excitação.

To estimate the direct medical costs of advanced non-small cell lung cancer care. We assessed a cohort of 277 patients treated in the Brazilian National Cancer Institute in 2011. The costs were estimated from the perspective of the hospital as a service provider of reference for the Brazilian Unified Health System. The materials and procedures used were identified and quantified, per patient, and we assigned to them monetary values, consolidated in phases of the assistance defined. The analyses had a descriptive character with costs in Real (R$). Overall, the cohort represented a cost of R$2,473,559.91, being 71.5% related to outpatient care and 28.5% to hospitalizations. In the outpatient care, costs with radiotherapy (34%) and chemotherapy (22%) predominated. The results pointed to lower costs in the initial phase of treatment (7.2%) and very high costs in the maintenance phase (61.6%). Finally, we identified statistically significant differences of average cost by age groups, education levels, physical performance, and histological type. This study provides a current, useful, and relevant picture of the costs of patients with non-small cell lung cancer treated in a public hospital of reference and it provides information on the magnitude of the problem of cancer in the context of public health. The results confirm the importance of radiation treatment and hospitalizations as the main components of the cost of treatment. Despite some losses of follow-up, we assess that, for approximately 80% of the patients included in the study, the estimates presented herein are satisfactory for the care of the disease, from the perspective of a service provider of reference of the Brazilian Unified Health System, as it provides elements for the management of the service, as well as for studies that result in more rational forms of resource allocation. Estimar os custos médicos diretos da assistência ao câncer de pulmão não pequenas células avançado. Foi avaliada uma coorte de 277 pacientes matriculados no Instituto Nacional do Câncer em 2011. Os custos foram estimados sob a perspectiva do hospital como prestador de serviços de referência para o SUS. Insumos e procedimentos utilizados foram identificados e quantificados, por paciente, sendo a eles atribuídos valores monetários, consolidados por fases da assistência definidas. As análises tiveram caráter descritivo com custos em reais (R$). Em termos globais, a coorte representou um custo de R$2.473.559,91, sendo 71,5% relacionados à atenção ambulatorial e 28,5% as internações. Na atenção ambulatorial, predominaram os custos com radioterapia (34%) e quimioterapia (22%). Os resultados apontaram para custos menores na fase inicial de tratamento (7,2%) e custos muito elevados na fase de manutenção (61,6%). Por fim, identificaram-se diferenças estatisticamente significativas das médias dos custos por faixas etárias, níveis de escolaridade, desempenho físico e tipo histológico. Este estudo fornece um retrato atual, útil e relevante sobre os custos de pacientes com câncer de pulmão não pequenas células assistidos em um hospital público de referência e provê elementos sobre a magnitude do problema do câncer no âmbito da saúde pública. Os resultados ratificam a importância do tratamento radioterápico e das internações como principais componentes de custo do tratamento. Apesar de algumas perdas de seguimento avalia-se que, para cerca de 80% dos pacientes incluídos no estudo, as estimativas aqui apresentadas sejam satisfatoriamente fidedignas ao cuidado da doença, sob a perspectiva de um prestador de referência do SUS, fornecendo elementos para a gestão do serviço, bem como para estudos que redundem em formas mais racionais de alocação de recursos.

Este trabalho é parte integrante da pesquisa de mestrado acadêmico em ensino de ciências. Nele, busca-se apresentar os resultados da pesquisa realizada entre os 106 alunos do curso superior de tecnologia em automação industrial do Instituto Federal de Educação, Ciência e Tecnologia de São Paulo campus Cubatão, divididos em cinco turmas, duas no período matutino e três no período noturno. A análise dos resultados deste pré questionárioconstatou a falta de conhecimento básico dos discentes, sobre assuntos relacionados à astronomia, o que pode ser atribuído ao ineficiente processo de aprendizado pelo qual eles passaram tanto no ensino médio como no ensino fundamental, em escolas municipais, estaduais e particulares onde estudaram. No ensino de astronomia, têm-se diagnosticado constantemente diversas dificuldades conceituais tanto por parte de alunos como de professores de todas as áreas e níveis de ensino e poucos de fato a compreendem (ALBRECHT; VOELZKE, 2010). Demonstra-se as duas etapas concluídas do trabalho. A primeira etapa indica a análise dos conhecimentos prévios sobre conceitos astronômicos, através do questionário com 25 perguntas. A fim de corrigir as falhas constatadas, experimentalmente ministrou-se, externo ao conteúdo programático, um curso básico em astronomia, com diferentes estratégias de ensino, tais como, utilização de aulas expositivas dialogadas, recursos audiovisuais e palestras, para corrigir as dificuldades diagnosticadas. Essas estratégias de ensino se comprovaram adequadas às necessidades dos alunos e os conceitos foram finalmente compreendidos. Ao término do curso, completado o interstício de 120 dias, para caracterizar que houve a aprendizagem significativa, realizou-se uma nova pesquisa, quando, exatamente os mesmos 106 alunos responderam as mesmas 25 questões aplicadas na primeira etapa. Constata-se na segunda etapa, após análise, que em todas as questões, houve maior compreensão dos assuntos abordados e os alunos obtiveram uma melhora significativa no aprendizado dos conceitos relacionados à astronomia. Nota-se que a astronomia está presente e é elemento importante dos parâmetros curriculares nacionais e que há muito interesse por parte dos alunos com relação ao tema. Diante dos resultados obtidos no pós-curso, pode-se afirmar que o curso básico em astronomia, realizado na própria escola, mas externo ao conteúdo programático, proporcionou uma integração entre os alunos, estreitando os laços de amizade e do conhecimento entre eles não importando a turma ou o período pois a dificuldade inicial foi vencida por todos, com muita dedicação e comprometimento entre todos; hoje estes alunos podem seguramente continuar estudando estes conceitos de astronomia.

Nowadays is widely well know that the potato is an important vegetable crop at Brazíl. It is grown on about 173.000 ha, with total yield of 2.6 million tons year-1. The average yield is 15 t ha-1. This level is very low because degeneration of crop is rapid under high temperature and high viruses pressure. Therefore seed potato propagation and production is principal on consumption potato production. This is why we found it necessary to develop it. The latossolo vermelho soil-farmyard manure- burnt rice straw-fertilizer 4N:14P:8K greenhouse pot trial was set up at the National Vegetable Crops Research Center, Brasília-DF, Brazíl in 1990. The methods of the experiments were soil x farmyard manure x burnt rice straw, soil x 4N:14P:8K fertilizer and soil x farmyard manure x burnt rice straw x 4N:14P:8K fertilizer on randomized block design in total 29 combination of treatments in 5, 5 and 3 repetitions with in a total parcel of 116. According to chemical analysis of the a., soil, b., farmyard manure and c., burnt rice straw the agrochemistry parameters were as follows (estimated datas): a., latossolo vermelho soil: CaCO3 0.3-0.7%, humo 0.9-1.0%, pH (H2O) 5.3, pH (KCl) 4.5, AL- P2O5 3.2-3.5 mg kg-1, AL- K2O 180 mg kg-1, Mg (KCl) 70 mg kg-1, EDTA-Zn 0.5-0.8 mg kg-1, EDTA-Cu 0.5-0.6 mg kg-1, b., farmyard manure: N 1.8 g kg-1, P2O5 2.0 g kg-1, K2O 4.0 g kg-1, c., burnt rice straw: N 0.8 g kg-1, P2O5 7.0 g kg-1, K2O 4.5 g kg-1. The experimental datas were estimated by analysis of variance, ANOVA and MANOVA. The main conclusions were as follows: 1. Mixture of 80% latossolo vermelho, 10% burnt rice straw and 10% farmyard manure were shown best performance on seed potato productivity. The piece of tubers with a 0-20 mm (consumption seeds) was increased by 77%. 2. Total seed potato number was reached maximum at 10.8 g pot-1 4N:14P:8K fertilizer regarding to average of treatments with a 33%. 3. Dry biomassa production plant-1 was decreased by high dose of 4N:14P:8K fertilizer (18.0 g pot-1) with a hard effect (57%). Our results are shown that it was possible developing of the seed potato production under tropical greenhouse conditions by optimalised soil-organic matter-fertilizer system. This datas should be as indicators to sustainable field potato advisory systems. Keywords: potato (Solanum tuberosum L.), greenhouse, latossolo vermelho soil, farmyard manure, burnt rice straw, 4N:14P:8K fertilizer, sustainability, yield Introducáo: Importância e situação actual em produção da batata no Brazíl A batata é atualmente uma das hortaliças de maior importância no Brasíl (Márton 2000a., 2000b.) com um cultivo annual médio de 173.000 ha e uma produção de 2600000 t. A produtividade médio nacional é de 15 t ha-1, muito baixa se considerar que é possivel a obtenção de rendimentos acima de 40 t ha-1. Observa- se também, que existe variação no produtividade entre regiões e estados. E importante como fonte de alimento pelo seu alto valor nutricional a quantidade produzida muito superior por unidade de área a tempo, se comparada com diversas outras culturas (László 2000b., 2000c.). Os estados que tradicionalmente produzem batata em maior ou menor escala são indicados em seguente: Pernambuco, Ceará, Sergipe, Goiás, Mato Grosso, Mato Grosso do Sul, Rondonia e Acre. Os plantios predominantes são o das águas e das secas, sendo o de inverno bem menos expressivo, pois poucas áreas permitem o seu cultivo, na maioria dos casos necessitando- se de irrigação. Considerando as três épocas de plantio e diferentes condições climaticas brasileiras, podemos definir de um modo geral o plantio de batata no Brasíl da seguinte maneira: Nordeste e Centro- Oeste- plantio de inverno, Sudeste- plantio das águas, secas e inverno, Sul- plantio das aguas, secas e inverno. Sendo este último em áreas muito limitadas. Dentre as hortaliças a batata é uma das culturas mais estudadas actualmente. Os principais problemas que afetam a cultura da batata podem ser de ordem agronómica, economica e comercial. Como exemplos destes podem ser citados: o uso racional de matérias orgânicos, esterco de curral e inorgânico fertilizantes. Efeito de materias orgnicânicos e N, P, K elementos minerais para produção da batata As necessidades em N, P, e K elementos minerais da batata são superidas pela aplicação apropriada de matérias orgânicos, esterco de currals, fertilizantes ao solo, combinada com a ambiente (Márton 2001a., 2001b.), época adequada e posição ideal de aplicá- lo. Efeito da materias orgânicos O suprimento de N á batateira provém principalmente da matéria orgânica do solo e do fertilizante aplicado (László 2000a., Márton et all. 2000.). Embora não seja muito praticado no Brasíl, a incorporação de esterco ao solo é fator de aumento da produção de tuberculos. Este resultado favorável poderia ser atribuído ao melhoramento da estrutura do solo, á maior retenção de água pelo e mesmo favorecendo o melhor desenvolvimento do sistema radicular da planta. A batata pode ser cultivada em todo tipo de solo desde que tenha boa drenagem e seja bem estruturado. Isto é tem que ser bem aerado e permitir o bom desenvolvimento dos órgãos subterráneos da batateira. Sem de matéria orgânicos e esterco de curral a tendencia de determinados solos formar crosta, oferecendo uma alta resisténcia mecánica á emergéncia das plantas, pode ser um determinante de stands desuniformes. A cause primaria da formação de crostas é a destruição dos agregados do solo pela excessiva manipulação mecánica resultando em aeração reduzida e aumento da densidade e coesão das particulas do solo. O encrostamento do solo pode ser reduzido através com matérias orgânicos. De maneira geral, a produção de tuberculos em solo de baixa potencialidade (aqueles em que a penetração das raizes é dificultada pela compactação, textura argilosa ou com camadas no solo) será menor do que nagueles com alta potencialidade (boa textura e adequada retenção de agua). Efeito do nitrogênio No Brazíl em todas regiões onde se cultiva batata é raro encontrar solos com elevado teor de nitrogênio e que não precisam de quantidades desta elemento. É o elemento que governa o padrão de desenvolvimento da planta, estimulando principalmente o crescimento da parte aérea (Kádár et all. 2000., László 2000.). Para se obter rendimento de tubérculos é necessário um rápido e curto periodo de desenvolvimento da parte aérea e uma fase de acúmulo maior possível. Para tanto, devem ser evitadas doses muito altas de nitrogênio e, principalmente, se aplicadas tardiamente, pois haverá demasiado desenvolvimento de folhas que demorarão mais a finalizar seu crescimento e maturação. Isto implicará na redução do periodo de intenso desenvolvimento dos tubérculos e armazenagem do amido, resultando em menor produção. Há risco para a saúde na ingestão de alimentos com altos teores de nitrato e nitrito, havendo preocupação com o efeito de doses mais altas de nitrogênio sobre os teores dos mesmos nos tuberculos. Embora haja diferenças entre cultivares, localidades e períodos de armazenamento, há estudos mostrando que a fertilização com até 150 kg ha-1 de nitrogênio não foi suficiente para propiciar niveis preocupantes de nitrato nos tuberculos colhidos. Efeito do fósforo A grande maioria dos solos brasileiros cultivados com batata apresentam limitações ao bom desenvolvimento e produção da cultura em função dos baixos níveis de fósforo. Isto significa que aumentos de produção quase sempre ocorrem quando o solo recebe adubação fosfatada (László 2001a.). Estes aumentos são mais marcantes em solos nunca antes adubados ou com baixo teor de fósforo. Nestes, dificilmente alcanca- se a produção máxima com níveis reduzidos de fósforo. Não seria exagerado supor níveis de 600 a 800 kg ha-1 de P2O5, como sendo aqueles que iriam proporcionar produção máximas, principalmente em solos mais ácidos e pobres em matéria orgânico. A adubação fosfatada é muito importante no crescimento inicial da planta e, além de aumentar a produção de tuberculos em peso e números, aumenta também a quantidade e qualidade do amido neles contidos e reduz perdas durante o armazenamento dos mesmos. A quantidade de fósforo a aplicar dependerá da análise do solo considerando- se principalmente o nível de P existente e a textura do solo. Solos de textura média e arenosa necessitam maior conteúdo de fósforo do que os de textura argilosa para serem considerandos solos de baixo, médio ou alto teor de fósfato. Efeito da potássica Embora seja o elemento mais absorbido pela batateira, nem sempre há resposta positiva da aduba potássica sobre o rendimento da cultura. Provavelmente isto esteja relacionado com níveis elevados deste elemento no solo (Kurnik et all. 2001.). Entretanto, em solos com médios e baixos teores de potássio, aumentos significativos são conseguidos. Por isto, as recomendações de adubação com potássio, nas diversas regiões do mundo, variam de 50-300 kg ha-1 de K2O. Resultados de trabalhos em brasiléiros têm demonstrado que a aduba potássica pode ser substituída pela aplicação de 150 m3 ha-1 de vinhaça de cana de açúcar. Ao elevar- se a dose de fertilização potássica deverá haver precaução para que a adubação magnesiana seja suficiente. O K além de aumentar a produção, em solos deficientes, aumenta também o tamanho dos tubérculos produzidos, e a proporção de tubérculos grandes. Deficiência no suprimento de potássio á planta pode acarretar produção de tubérculos com elevada susceptibilidade aos danos mecánicos pós-colheita. Os tubérculos injuriados enegrecem facilmente e este enegrecimento é inversamente proporcional á quantidade de potássio nos tuberculos. Ademais, quando fritos dão origem a um produto escuro, de baixa valor comercial. Manejo de adubação Diversos fatores como potencial de produção do solo, modo de aplicação do fertilizante dentre outro fatores afetam a resposta da batateira á aplicação de fertilizantes (Refschneider 1987.). Depreende- se pois que no estabelecimento de um nivel ideal de fertilização as variáveis planta, solo e condições climaticas devem ser visualizadas como um sistema pouco provável de ser homogeneo mesmo em nivel de fazenda. Como tal, generalizações a respeito de doses ou niveis de fertlização são difíceis de serem feitas, recomendações exigem julgamento hábil por parte do fazendeiro ou do tecnico responsavel pela cultura (Márton 2001a., 2001b.). Este julgamento será mais preciso conhecendo- se pontos que serão rápidamente discutidos a seguir. A taxa de absorção de nutrientes é governada pela concentração externa ou suprimento de nutrientes pelo solo e a demanda do nutriente criada pelo desenvolvimento e funcinamento normal dos diversos órgãos das plantas. O nivel de nutrientes na solução do solo deve ser suficiamente alto para que suas taxas de absorção não sejam limitantes ao crescimento. Por outro lado, não deve ser demasiado para causar excessiva absorção de outros nutrientes. Forte associação existe entre a absorção de nutrientes e o desenvolvimento da planta. De maneira geral, a fase de rapido desenvolvimento da cultura é acompanhada por um grande aumento na absorção de nutrientes com a taxa de absorção declinado quando a taxa de crescimento diminuiu. Normalmente todos os fertilizantes potássicos e fosfatados são adicionados ao solo na época do plantio. O nitrogênio normalmente é parcelado. Cerca de 2 por 3 do nível recomendado é colocado no sulco de plantio e o restante adicionado por ocasião da amontoa. É uma prática tradicinal e com pouco suporte experimental no condiõces brasileiras. Espera -se que a aplicação parcelada do nitrogênio e mesmo do potássio possem ser benéficas quando houver chuva excessiva ou irrigações mal executadas principalmente em solos mais arenosos onde poderá ocorrer a lixiviacão dos mesmos (Márton 2001a., 2001b.). O parcelamento poderá também ser benéfico quando elevados níveis de fertilizantes porém recomendandos e a aplicação por feita nos sulcos de plantio, pois evitar-se ia assim, elevada concentração salina em torno dos tubérculos plantados, embora a aplicação á lanco, em toda área, possa ser opção vantajosa. Quantidades corretas de fertilizantes, posição ideal e época certa de aplicação, combinadas adequadamente, definem o programa de adubação da batata. Esse programa é variável de acordo com o solo, a batata e condisões ambientais (Márton 2001a.). A dose de um elemento a ser aplicada em batata, é função da quantidade desse elemento suprida pelo solo e da percentagem de recuperação do elemento adicionado ao solo como fertilizante. Resultados experimentais comparando a aplicação de fertilizante á lanco ou localizado mostram respostas variadas sobre a produção. E possivel encontrar resultados iguais em ambos os métodos, de supremacia da aplicação á lanco ou da aplicação localizada (Kurnik et all. 2001.). Parece que baixas quantidades de fertilizantes são mais eficiemente utilizadas quando aplicação nos sulcos de plantios. Entretanto o potancial de produção pode ser aumentando com alta ou mesmo moderada quantidade de fertilizantes aplicados á lanço. A recomendação geral de colocar o adubo no sulco de plantio da batata merece ser questionada. É uma recomendação válida ao entender- se que a batata responde bastante á aplicação de fósforo, que os solos brasileiros tem alta capacidade de absorção de fósforo e que haverá maior proliferação de raízes na área fertilizada. Uma indagação aparece: um solo com baxa disponibilidade de fósforo fora da zona fertilizada permitiria o desenvolvimento ótimo da planta. Algumas evidéncias mostram, para outras espécies, que grande parte do sistema radicular, deve estar exposta ao fósforo para suprir as necessidades das plantas. Ademais, há um determinado valor de concentração de fósforo, na solução do solo, acima da qual a taxa de absorção não é aumentada. Essas considerações suscitam a possibilidade de questionar se a aplicação de fósforo em sulcos seria a forma mais eficiente de usá-lo quando se pretende alcancar elevadas produções. Deve-se lembrar entretanto, que solos tropicais, ainda com baixos teores fósforo e alta capacidade de adsorção, seria necessária dose muito elevada de P, quando aplicada á lanço, em todo o terreno. Se a aplicação localizada do fósforo pode, em parte, ser explicada, a do nitrogênio e potássio não são facilmente justificadas sob o aspecto de eficiéncia de utilização. Pelo contrário, ela pode ser questionada, principalmente pelas suas caracteristicas de difusão, pelo efeito que altas concentração de amónio e cloreto podem ter sobre a pressão osmotica da solução do solo junto aos tubérculos plantados, pelo efeito negativo do cloreto sobre a absorção de fósforo e também sobre a capacidade produtiva das plantas. Portanto, existe a possibilidade de ocorrer toxidez de amónio e de cloreto ao se aplicar doses altas dos fertilizantes nos sulcos de plantios. Isto pode determinar uma menor eficiéncia no uso dos fertilizantes. Materiais e Metodos: Nos desenvolverémos os três experimentos (i.e.: 1., 2., 3.) para aumentár-se do produção e produtividade da batata (Solanum tuberosum L.) semente pré- básica no casa de vegetação com diferentes doságens do latossolo vermelho novo, do esterco de curral e do adubo fórmula 4N:14P:8K no Empresa Brasileira de Pesquisa Agropecuaria- Centro Nacional de Pesquisas de Hortaliças, da Brazília-DF no 1990.

Para produção aplicarémos sistema de proteção de plantas como usados no Brasíl. Ambiente foi controlado com ventilação automatizado. Temperatura médio foi 22 0C e humidade médio foi 68% durante de experimento. A data de colheta foi 04.07.1990. As pesagens foram feitos como peso fresco. Os resultados foram submetidos a analise de variáncia, ANOVA. As doságens de adubo foram como a seguir no Tabela 2. Experimento 3. Efeito de latossolo vermelho novo, palha de arroz queimado e adubo 4N:14P:8K para produção da batata semente pré- básica em casa de vegetação Para pesquisar estes efeitos o experimento tipo de (2 x 6) foi instalado considerando-se as combinações entre duas misturas (i.e.: 1., 2.) e seis doságens de adubo complexo 4N:14P:8K, com três repetições, no delineamento experimental de bloco ao acaso, sendo 1 vaso (3000 cm3 volume de capacidade de vasos preto) por parcela na mésas experimentais em casa de vegetação. O adubo foi posicionando no solo de 4 cm abaixo de superficie do solo. A cultivar utilizada foi Baraka e o tamanho de tuberculos foi com 0-20 mm. A data de plantio foi 25.09.1990. Plantarémos em cada vaso 3-3 tuberculos com embaixo de 4cm de superficie da mistura no vasos. Irrigarémos com 12 mm quantidade da augua 2 vezes por semana. Para produção aplicarémos sistema de proteção de plantas como usados no Brasíl. Ambiente foi controlado ventilação automatizado. Temperatura médio foi 21 0C é humidade médio foi 66% durante de experimento. A data de colheta foi 14.12.1990. As pesagens foram feitos como peso fresco e matéria seca. Os resultados foram submetidos a analise de variáncia, MANOVA. Os manejos foram como a seguir no Tabela 3. Resultados e Discuscáo Experimento 1. Efeito de diferentes misturas para produção da batata semente pré- básica em casa de vegetação O tratamento 3. i.e.: mistura de 80% latossolo vermelho novo, 10% palha de arroz queimado e 10% esterco de curral, apresentou os maiores valores para numero de tuberculos com 0-20 mm (tamanho de comercial), peso de tuberculos com 0-20 mm e peso total de tuberculos por vaso. Porém, não houve diferencas significativas para o numero tuberculos comerciais, i.e.: com 0-20 mm, para os tratamentos 2., 3., 4., e 5. Portanto, a mistura poderá ter uma composição entre 60 a 90% de latossolo vermelho novo, 6 a 24% de palha de arroz queimado e de 4 a 16% de esterco de curral. Não houve diferenca significativa entre a mistura padrão utilizada e as misturas incluidas nos extremos indicados anteriormente. Porém, a mistura padrão recebeu adubação quimica de 4N:14P:8K (3.6 grama vaso-1) e calcário na dosagem de 4.2 grama vaso-1, o que não aconteceu com as parcelas das misturas em analise. Experimento 2. Efeito de adubo 4N:14P:8K para produção da batata semente pré- básica em casa de vegetação Há um efeito crescente das dóses de 4N:14P:8K nos caracteres observados. Porém, a maior dóse não chegou a ultrapassar a mistura padrão. Experimento 3. Efeito de latossolo vermelho novo, palha de arroz queimado e adubo 4N:14P:8K para produção da batata semente pré- básica em casa de vegetação Efeitos de misturas As duas misturas (i.e.: 1 e 2) deram resultados significativos mais alto que a mistura padrão, em média 54 %. Entre as misturas 1 e 2, foi melhor a 2. (80% latossolo vermelho novo, 10% palha de arroz queimado, 10% esterco de curral). Examinando-se 15 fatores, entre 11 casos afirmou-se a mistura como para melhor que a mistura 1. (70% latossolo vermelho novo, 20% palha de arroz queimado, 10% esterco de curral). Em caso de número de tuberculos 0-20 mm com a mistura 2. foi possivel aumentar geralmente os números de tuberculos em 77% que a mistura padrão. Efeitos de adubação 1. Área da folhas por planta entre manejo foi melhor de modo significativo a doságem de 3.6 grama vaso-1 adubo complexo (3103 cm2 plantas-1). 2. Peso fresco da folhas e de hastes por plantas as tendencias foram parecidos com o da área de folhas. 3. Peso fresco de raizis por planta até 7.2 grama vaso-1 diminuiu depois aumentou. 4. Peso fresco total de tuberculos por planta as crescentes doságens de um modo forte diminuiram a produção de tuberculos de 0 e 18.0 grama vaso-1 em 160% em os dois caso da mistura. 5. Peso de fitomassa fresco por planta foi melhor a 3.6 g vaso-1 (239 grama planta-1 em médio da dois mistura), depois os dados diminuirám. 6. Produção de biomassa fresco por planta a maxima produção (188 grama planta-1) foi obtida com 3.6 grama vaso-1. Deste ponto de modo forte caiu a produção. 7. Peso da matéria seca de folhas, hastes e raizis por planta somente em caso de mistura padrão o resultado foi significativo em relação aos outros tratamentos. 8. Péso da matéria seca de tuberculos total por planta modo significativo diminuiu a produção (0 e 18.0 grama vaso-1 = 360%) em médio da duas misturas. 9. Biomassa produção de materia seca por planta modo significativo diminuiu para efeito de alta dosagens de adubo complexo (0 e 18.0 grama vaso-1 = 158%) em médio da duas misturas. 10. Peso fresco de tuberculos com 0-20 mm as crescentes dosagens de 0 e 18.0 grama vaso-1 diminuiram a produção em 213% em médio da duas misturas. 11. Peso fresco de tuberculos com 20 mm-1 as crescentes dosagens de 0 e 18.0 grama vaso-1 diminuiram a produção assima de 250% em médio da duas misturas. 12. Numero de tuberculos 0-20 mm e 20 mm- por planta com os manejos de 0 e 18.0 grama vaso-1 foi possível aumentar em media 200% sobre a mistura padrão. Os manejo de 18.0 grama de adubo vaso-1 já causaram importante diminuição em relação caso a absoluto controle. 13. Numero total de tuberculos por planta entre manejos foi melhor a dosagem de 7.2 grama vaso-1 adubo complexo 4N:14P:8K comparando da mistura padrão. Nos verificamos-se que a mistura padrão sempre deu menor rasultados do que as outras misturas (i.e.: 1 e 2). Entre as misturas 1 e 2 a melhor foi a número 2. (80% latossolo vermelho novo, 10% palha de arroz queimado, 10% esterco de curral). Com esta mistura e com relação a mistura padrão, foi possível aumentar o número de tuberculos 0-20 mm com 77%. No caso do adubação, verificamos que grande quantidades de adubo acima de 7.2 grama vaso-1, de modo rigoroso diminuiu a produção de batata-semente pré- básica. Este fato deve ser considerado para a eleição das dosagens de adubos. Deve-se indicar o caso de número de tuberculos acima 20 mm-, onde em relação mistura padrão foi possivel aumentar em média 73% os resultados.

TENDINOPATHY AND OBESITY.

Castro, Adham do Amaral E; Skare, Thelma Larocca; Nassif, Paulo Afonso Nunes; Sakuma, Alexandre Kaue; Barros, Wagner Haese

Tendinopathies and tendon tears account for over 30% of all musculoskeletal consultations. Obesity, which is becoming one of the world´s most prevalent public health issues, may be associated with this condition. To review the literature about tendinopathies and obesity association. This is a descriptive exploratory study using the portal Medline. Literature in English language from 2006 to 2014 were reviewed. The pathogenesis of tendinopathies includes inflammatory, regenerative and degenerative processes that happen simultaneously from early to late phases of the disease. Mechanical stress upon tendons seems to be one of the most important factors to initiate the inflammatory response, but it´s not the only one that can deflagrate it: there are other extrinsic, genetic and metabolic factors that may be involved. Therefore, tendinopathies in obese patients can be due to tendon overload because of the excess of weight, but also because of increased production of pro-inflammatory mediators related to fat tissue such as adipokines. This pro-inflammatory state that obese people can suffer is known as adiposopathy, or sick fat syndrome. Weight loss is associated with decrease in adipokines and improvement of musculoskeletal symptoms. The relation of obesity and tendinopathies is supported by evidences of recent studies, exemplified in this review of literature. As tendinopatias e as fissuras em tendões respondem por 30% de todas as consultas médicas. A obesidade, que está se tornando um dos problemas de saúde pública mais prevalentes no mundo, pode estar associada com esta condição. Revisar a literatura acerca da associação entre obesidade e tendinopatias. Este é um estudo exploratório e descritivo utilizando artigos em língua inglesa do portal médico Medline, do período de 2006 a 2014. Na patogênese das tendinopatias incluem-se elementos inflamatórios, regenerativos e degenerativos que aparecem de maneira simultânea em todos os estágios da doença. O estresse mecânico sobre os tendões parece ser um dos mais importantes na promoção do processo inflamatório inicial. Todavia não é o único. Existem fatores ambientais, genéticos e metabólicos atuando de maneira ativa. Portanto, as tendinopatias em indivíduos obesos podem se dever à sobrecarga mecânica pelo excesso de peso, mas, também, pelo aumento na produção de mediadores pró-inflamatórios relacionados ao tecido adiposo, como as adipocinas. O estado pró-inflamatório existente no indivíduo obeso é conhecido como adiposopatia ou síndrome da "gordura doente". A perda de peso está associada com decréscimo das adipocinas e diminuição da sintomatologia musculoesquelética. A associação da obesidade com tendinopatias tem sido fundamentada em estudos recentes como os desta revisão de literatura.

Gradientes radiais de abundância são observados no disco de nossa Galáxia e também em outras galáxias espirais. No caso da Galáxia, o principal problema relativo aos gradientes é sua variação temporal, que constitui um dos principais vínculos aos modelos de evolução química da Galáxia. As nebulosas planetárias são particularmente interessantes no estudo dos gradientes e suas variações, tanto espaciais como temporais. São objetos brilhantes, podendo ser observadas a grandes distâncias, e têm abundâncias relativamente precisas de diversos elementos químicos. Além disso, sendo originadas de estrelas com massas entre 0.8 e 8 massas solares na sequência principal, incluem objetos com idades e populações diferentes, o que as torna especialmente interessantes ao estudo da variação temporal dos gradientes. Neste trabalho, apresentamos resultados recentes sobre a variação temporal do gradiente de O/H a partir de uma amostra contendo cerca de 200 nebulosas, para as quais obtivemos distâncias por métodos estatísticos. As abundâncias foram parcialmente obtidas a partir de observações em Itajubá e La Silla, sendo as restantes obtidas da literatura. Os resultados mostram, pela primeira vez, evidências de um achatamento do gradiente de O/H, de -0.11 dex/kpc para -0.06 dex/kpc nos últimos 9 giga-anos ou de -0.08 dex/kpc para -0.06 dex/kpc nos últimos 5 giga-anos. Esses valores apresentam um bom acordo com alguns modelos recentes para a evolução química da Galáxia. (FAPESP/CNPq)

Active corrosion protection of AA2024 by sol-gel coatings with corrosion inhibitors =

NASA Astrophysics Data System (ADS)

Yasakau, Kiryl

A industria aeronautica utiliza ligas de aluminio de alta resistencia para o fabrico dos elementos estruturais dos avioes. As ligas usadas possuem excelentes propriedades mecanicas mas apresentam simultaneamente uma grande tendencia para a corrosao. Por esta razao essas ligas necessitam de proteccao anticorrosiva eficaz para poderem ser utilizadas com seguranca. Ate a data, os sistemas anticorrosivos mais eficazes para ligas de aluminio contem cromio hexavalente na sua composicao, sejam pre-tratamentos, camadas de conversao ou pigmentos anticorrosivos. O reconhecimento dos efeitos carcinogenicos do cromio hexavalente levou ao aparecimento de legislacao banindo o uso desta forma de cromio pela industria. Esta decisao trouxe a necessidade de encontrar alternativas ambientalmente inocuas mas igualmente eficazes. O principal objectivo do presente trabalho e o desenvolvimento de pretratamentos anticorrosivos activos para a liga de aluminio 2024, baseados em revestimentos hibridos produzidos pelo metodo sol-gel. Estes revestimentos deverao possuir boa aderencia ao substrato metalico, boas propriedades barreira e capacidade anticorrosiva activa. A proteccao activa pode ser alcancada atraves da incorporacao de inibidores anticorrosivos no pretratamento. O objectivo foi atingido atraves de uma sucessao de etapas. Primeiro investigou-se em detalhe a corrosao localizada (por picada) da liga de aluminio 2024. Os resultados obtidos permitiram uma melhor compreensao da susceptibilidade desta liga a processos de corrosao localizada. Estudaram-se tambem varios possiveis inibidores de corrosao usando tecnicas electroquimicas e microestruturais. Numa segunda etapa desenvolveram-se revestimentos anticorrosivos hibridos organico-inorganico baseados no metodo sol-gel. Compostos derivados de titania e zirconia foram combinados com siloxanos organofuncionais a fim de obter-se boa aderencia entre o revestimento e o substrato metalico assim como boas propriedades barreira. Testes industriais mostraram que estes novos revestimentos sao compativeis com os esquemas de pintura convencionais actualmente em uso. A estabilidade e o prazo de validade das formulacoes foram optimizados modificando a temperatura de armazenamento e a quantidade de agua usada durante a sintese. As formulacoes sol-gel foram dopadas com os inibidores seleccionados durante a primeira etapa e as propriedades anticorrosivas passivas e activas dos revestimentos obtidos foram estudadas numa terceira etapa do trabalho. Os resultados comprovam a influencia dos inibidores nas propriedades anticorrosivas dos revestimentos sol-gel. Em alguns casos a accao activa dos inibidores combinou-se com a proteccao passiva dada pelo revestimento mas noutros casos tera ocorrido interaccao quimica entre o inibidor e a matriz de sol-gel, de onde resultou a perda de propriedades protectoras do sistema combinado. Atendendo aos problemas provocados pela adicao directa dos inibidores na formulacao sol-gel procurou-se, numa quarta etapa, formas alternativas de incorporacao. Na primeira, produziu-se uma camada de titania nanoporosa na superficie da liga metalica que serviu de reservatorio para os inibidores. O revestimento sol-gel foi aplicado por cima da camada nanoporosa. Os inibidores armazenados nos poros actuam quando o substrato fica exposto ao ambiente agressivo. Numa segunda, os inibidores foram armazenados em nano-reservatorios de silica ou em nanoargilas (halloysite), os quais foram revestidos por polielectrolitos montados camada a camada. A terceira alternativa consistiu no uso de nano-fios de molibdato de cerio amorfo como inibidores anticorrosivos nanoparticulados. Os nano-reservatorios foram incorporados durante a sintese do sol-gel. Qualquer das abordagens permitiu eliminar o efeito negativo do inibidor sobre a estabilidade da matriz do sol-gel. Os revestimentos sol-gel desenvolvidos neste trabalho apresentaram proteccao anticorrosiva activa e capacidade de auto-reparacao. Os resultados obtidos mostraram o elevado potencial destes revestimentos para a proteccao anticorrosiva da liga de aluminio 2024.

Epidemiology is the study of occurrence, distribution and determinants of health-related events, including the application of that knowledge to the prevention and control of health problems. However, epidemiological studies, in most cases, have limited their research questions to determinants of health outcomes. Research related to the application of knowledge for prevention and control of diseases have been neglected. In this comment, we present a description of how population attributable fraction estimates can provide important elements for planning of prevention and control of diseases in Brazil. RESUMO Epidemiologia é o estudo da ocorrência, distribuição e determinantes de eventos relacionados à saúde da população, incluindo a aplicação desse conhecimento para a prevenção e o controle dos problemas de saúde. Entretanto, estudos epidemiológicos, na maioria das vezes, têm limitado suas perguntas de pesquisa aos fatores determinantes de desfechos em saúde. Pesquisas relacionadas à aplicação do conhecimento para ações de prevenção e controle de doenças têm sido negligenciadas. Nesse comentário, apresentamos uma descrição de como as estimativas de fração atribuível populacional podem fornecer importantes elementos para planejamento de ações de prevenção e controle de doenças no Brasil.

Coerência espectroscópica de famílias de asteróides

2003-08-01

As Famílias de asteróides são caracterizadas como agrupamentos de objetos provenientes da quebra por colisão de corpos precursores. Desta forma, seus membros devem preservar relações genéticas que podem ser traduzidas sob a análise de suas características espectrais. Neste trabalho é apresentado o primeiro estudo espectroscópico de todas as famílias de asteróides do cinturão principal. Para tal, a divisão em famílias foi refeita utilizando-se o método HCM com uma base de elementos próprios analíticos (Knezevic e Milani, Jun 2001) e para o estudo espectroscópico foram utilizadas diversas campanhas de observação espectroscópica, tais o S3OS2 e o SMASSII, bem como outros dados disponíveis na literatura. A homogeneidade espectroscópica de cada família foi avaliada através da verificação das classes espectroscópicas presentes, bem como da comparação destes espectros com os de objetos de fundo, localizados na vizinhança da família. Vinte e duas famílias foram analisadas (as que possuíam mais do que 3 membros com espectro) e, dentre as principais conclusões pode-se citar a homogeneidade espectroscópica e, provavelmente mineralógica das famílias de Vesta, Eunomia, Hoffmeister, Dora, Merxia, Agnia, Koronis e Veritas. Esta última em particular, foi tida como uma família não homogênea espectroscopicamente em trabalho anterior (Di Martino et al. 1997). Outro resultado interessante é, por um lado, a aparente falta de homogeneidade dos membros da família de Eos, e por outro sua forte distinção dos objetos de fundo. O oposto ocorre na família de Themis, esta apresentando-se espectroscopicamente compatível com os objetos de fundo, mas com grande homogeneidade taxonômica entre seus membros. Algumas das famílias apresentam asteróides "intrusos" (objetos cujas características físicas não são compatíveis com aquelas dos membros da família) que, de modo geral desaparecem ao se considerarem níveis mais baixos de corte para a divisão da família no HCM, sem prejuízo para o agrupamento dos demais membros.

Health and innovation: economic dynamics and Welfare State in Brazil.

Gadelha, Carlos Augusto Grabois; Braga, Patrícia Seixas da Costa

The effective enforcement of the access to healthcare as fundamental right requires an important theoretical and political effort at linking the often contradictory economic and social dimensions of development. This study suggests the need for a systemic view of policies related to the industrial base and innovation in health and the construction of the Brazilian Unified National Health System (SUS). The authors investigate the relations between health, innovation, and development, seeking to show and update the political, economic, and social determinants of the recent Brazilian experience with the Health Economic-Industrial Complex (HEIC). They discuss how the agenda for innovation and domestic industrial production in health gained a central place in the project for construction of the SUS. The article thus seeks to link inherent issues from the agenda for development, production, and innovation to social policy in healthcare, as observed in recent years, and based on this analysis, points to political and conceptual challenges for implementing the SUS, especially as regards strengthening its technological and industrial base. As a byproduct, the article develops an analytical and factual focus on the consolidation of the HEIC in Brazil, both as a dynamic vector of industrial development, generating investment, income, employment, and innovations, and as a decisive element for reducing vulnerability and structural dependence in health. The authors aim to show that strengthening the SUS and orienting it to social needs is an essential part of building a social Welfare State in Brazil. Resumo: A efetivação da saúde como um direito fundamental exige importante esforço, teórico e político, de articulação das dimensões econômicas e sociais, por vezes contraditórias, do desenvolvimento. Este trabalho indica a necessidade de um olhar sistêmico das políticas relacionadas à base produtiva e de inovação em saúde e à construção do Sistema Único de Saúde (SUS). Investiga as relações entre saúde, inovação e desenvolvimento, buscando mostrar e atualizar os determinantes políticos, econômicos e sociais da experiência brasileira recente relacionada ao Complexo Econômico-Industrial da Saúde (CEIS). Mostra como a agenda da inovação e da produção nacional em saúde ganhou centralidade no projeto de construção do SUS. O artigo procura, assim, articular questões inerentes à agenda do desenvolvimento, da produção e da inovação com a política social em saúde, tal como observado nos últimos anos e, valendo-se de sua análise, aponta desafios políticos e conceituais para a efetivação do SUS, em especial no que se refere ao fortalecimento de sua base tecnológica e produtiva. Como desdobramento, desenvolve um enfoque analítico e factual que relaciona a consolidação do CEIS no Brasil tanto como um vetor dinâmico do desenvolvimento industrial, gerando investimento, renda, emprego e inovações, quanto como elemento decisivo para a redução da vulnerabilidade e da dependência estrutural em saúde. Procura mostrar que seu fortalecimento e direcionamento para as necessidades sociais é parte essencial da construção de um Estado de Bem-Estar Social no Brasi.

Parallel tiled Nussinov RNA folding loop nest generated using both dependence graph transitive closure and loop skewing.

RNA secondary structure prediction is a compute intensive task that lies at the core of several search algorithms in bioinformatics. Fortunately, the RNA folding approaches, such as the Nussinov base pair maximization, involve mathematical operations over affine control loops whose iteration space can be represented by the polyhedral model. Polyhedral compilation techniques have proven to be a powerful tool for optimization of dense array codes. However, classical affine loop nest transformations used with these techniques do not optimize effectively codes of dynamic programming of RNA structure predictions. The purpose of this paper is to present a novel approach allowing for generation of a parallel tiled Nussinov RNA loop nest exposing significantly higher performance than that of known related code. This effect is achieved due to improving code locality and calculation parallelization. In order to improve code locality, we apply our previously published technique of automatic loop nest tiling to all the three loops of the Nussinov loop nest. This approach first forms original rectangular 3D tiles and then corrects them to establish their validity by means of applying the transitive closure of a dependence graph. To produce parallel code, we apply the loop skewing technique to a tiled Nussinov loop nest. The technique is implemented as a part of the publicly available polyhedral source-to-source TRACO compiler. Generated code was run on modern Intel multi-core processors and coprocessors. We present the speed-up factor of generated Nussinov RNA parallel code and demonstrate that it is considerably faster than related codes in which only the two outer loops of the Nussinov loop nest are tiled.

Elastoplasticidad anisotropa de metales en grandes deformaciones

NASA Astrophysics Data System (ADS)

Caminero Torija, Miguel Angel

El objetivo de este trabajo es el desarrollo de modelos y algoritmos numericos que simulen el comportamiento del material bajo estas condiciones en el contexto de programas de elementos finitos, dando como resultado predicciones mas precisas de los procesos de conformado y deformacion plastica en general. Para lograr este objetivo se han desarrollado diversas tareas destinadas a mejorar las predicciones en tres aspectos fundamentales. El primer aspecto consiste en la mejora de la descripcion del endurecimiento cinematico anisotropo en pequenas deformaciones, lo cual se ha realizado a traves de modelos y algoritmos implicitos de superficies multiples. Ha sido estudiada la consistencia de este tipo de modelos tanto si estan basados en una regla implicita similar a la de Mroz o en la regla de Prager. Ademas se han simulado los ensayos de Lamba y Sidebottom, obteniendo, en contra de la creencia general, muy buenas predicciones con la regla de Prager. Dichos modelos podrian ser extendidos de forma relativamente facil para considerar grandes deformaciones a traves de procedimientos en deformaciones logaritmicas, similares a los desarrollados en esta tesis y detallados a continuacion. El segundo aspecto consiste en la descripcion de la anisotropia elastoplastica inicial. Esto se ha conseguido mediante el desarrollo de modelos y algoritmos para plasticidad anisotropa en grandes deformaciones, bien ignorando la posible anisotropia elastica, bien considerandola simultaneamente con la anisotropia plastica. Para ello ha sido necesario desarrollar primero un nuevo algoritmo de elastoplasticidad anisotropa en pequenas deformaciones consistentemente linealizado y sin despreciar ningun termino, de tal forma que se conserve la convergencia cuadratica de los metodos de Newton. Este algoritmo en pequenas deformaciones ha servido para realizar la correccion plastica de dos algoritmos en grandes deformaciones. El primero de estos algoritmos es una variacion del clasico algoritmo de Eterovic y Bathe para incluir la posibilidad de plasticidad anisotropa con endurecimiento mixto. Este primer algoritmo esta restringido a casos de isotropia elastica. La isotropia elastica es una hipotesis bastante habitual en plasticidad anisotropa y tiene la ventaja de que permite el uso de formulaciones mixtas u/p. El segundo algoritmo, mas complejo y general, incluye la posibilidad de elasticidad anisotropa, plasticidad anisotropa y endurecimiento mixto. Este algoritmo supone una contribucion importante ya que esta basado en hipotesis comunmente aceptadas y utilizadas en elastoplasticidad isotropa: descomposicion multiplicativa del gradiente de deformaciones en parte elastica y parte plastica, descripcion hiperelastica sencilla en funcion de deformaciones logaritmicas e integracion exponencial que conserva el volumen. Ademas, la estructura final del algoritmo es modular y relativamente sencilla, consistiendo en un pre- y un postprocesador geometrico y una correccion plastica realizada en pequenas deformaciones. El algoritmo esta consistentemente linealizado para conservar la convergencia cuadratica asintotica de los metodos de Newton y la forma final que toma dicha linealizacion es similar al caso de isotropia elastoplastica implementado; consiste en el modulo tangente algoritmico de pequenas deformaciones sobre el que se aplica una transformacion para convertirlo en el de grandes deformaciones. Todos estos modelos han sido implementados en un codigo propio de elementos finitos denominado DULCINEA, el cual tiene formulaciones lagrangianas totales y actualizadas para grandes deformaciones. Una de las tareas necesarias para poder realizar las simulaciones, ha sido el estudio e implementacion de diferentes elementos que no sufran el bloqueo volumetrico severo que se observa en formulaciones estandar basadas en desplazamientos. Este bloqueo se debe a la condicion de quasi-incompresibilidad que imponen los modelos de plasticidad desviadores y consiste en una respuesta exageradamente rigida de la solucion obtenida por el metodo de los elementos finitos estandar. Entre los elementos implementados cabe destacar el basado en la formulacion mixta u/p, que contiene una interpolacion adicional de grados de libertad de presion. Estos grados de libertad adicionales habitualmente son internos al elemento en mecanica de solidos. En este trabajo se ha desarrollado e implementado en DULCINEA una familia de elementos tridimensionales mixtos en grandes deformaciones que incluye el caso particular BMIX 27/27/4, basado en la formulacion u/p, constituido por 27 nudos, con 27 puntos de integracion estandar y 4 grados de libertad de presiones, y que pasa la condicion Inf-Sup o de Babuska-Brezzi. Sin embargo, se ha observado que la formulacion u/p presenta ciertas limitaciones bajo las hipotesis conjuntas de anisotropia elastica y anisotropia plastica. (Abstract shortened by UMI.)

To define the antecedents, consequents, and attributes of spiritual coping. Rodgers' evolutionary model for concept analysis was used to guide an integrative literature review of qualitative research. Six qualitative articles were included and elements that define and contextualize the concept were identified. Three new nursing diagnoses are proposed, based on qualitative findings. These new diagnoses should be submitted to clinical validation in different cultural and religious backgrounds, but the inclusion in the taxonomy highlights a holistic perspective concerning the spiritual dimension of patients' responses in life and health transitions, and so, bringing the approach to spirituality into nursing practice. Definir os antecedentes, os consequentes e os atributos de coping espiritual. MÉTODOS: Modelo evolucionário de análise de conceitos de Beth Rodgers baseado numa revisão integrativa de literatura de pesquisa qualitativa. Seis pesquisas qualitativas foram incluídas e os elementos que definem e contextualizam o conceito foram identificados. CONCLUSÕES: São propostos três novos diagnósticos de enfermagem, baseados na evidência de estudos qualitativos. IMPLICAÇÕES PARA A PRÁTICA: Estes novos diagnósticos devem ser submetidos a estudos de validação clínica em diferentes contextos culturais e religiosos, e quando incluídos na taxonomia estarão a enfatizar uma perspectiva holística das respostas dos pacientes relacionada à dimensão espiritual e, assim, promovendo a inclusão da espiritualidade na prática clínica. © 2017 NANDA International, Inc.

Datação do disco galáctico pela nucleocosmocronologia do [Th/Eu

NASA Astrophysics Data System (ADS)

del Peloso, E. F.; da Silva, L.; Arany-Prado, L. I.

2003-08-01

A nucleocosmocronologia emprega abundâncias de nuclídeos radioativos na datação de escalas de tempo astrofísicas. O 232Th é um nuclídeo radioativo com meia-vida de 14 Gano, enquanto que os dois isótopos mais abundantes do Eu são estáveis. O decaimento radioativo do Th modifica as razões de abundâncias [Th/Eu], fornecendo assim um meio de sondar a escala de formação das populações estelares. O objetivo deste trabalho é averiguar a possibilidade de estimar uma idade para o disco Galáctico através da nucleocosmocronologia do [Th/Eu] e investigar o nível de incerteza associado a esta estimativa. Para tanto, foi selecionada uma amostra de 20 estrelas anãs ou subgigantes de tipos espectrais F5 a G9, com -1,00 £ [Fe/H] £ +0,30 e idade(Gano) £ 13. As abundâncias de Th e Eu foram obtidas por síntese espectral das linhas localizadas em 4019,1 Å e 4129,7 Å, respectivamente. Uma comparação destas abundâncias com outros resultados da literatura demonstra que nossos valores apresentam dispersão 2 a 3 vezes menor que qualquer trabalho anterior. Os parâmetros atmosféricos e abundâncias dos elementos que contaminam as regiões espectrais destas linhas foram determinados por nós, de maneira totalmente autoconsistente, através de análise espectral detalhada diferencial em relação ao Sol. As idades estelares individuais foram determinadas através de curvas isócronas teóricas no diagrama HR. Foi realizada, então, uma análise cronológica dos gráficos [Th/Eu] vs. [Fe/H] e [Th/Eu] vs. idade. Os dados estelares foram comparados a curvas calculadas para 3 idades do disco Galáctico - 9, 12, 15 Gano - e foi estudada a sensibilidade à idade assumida no cálculo do ajuste destas curvas aos dados. Estas curvas foram calculadas com base num modelo analítico de evolução química da Galáxia que leva em consideração a formação de refugos, que são compostos pelos remanescentes da evolução estelar, pelos resíduos da formação de estrelas de baixa massa (planetas, cometas, etc.) e por quaisquer outros objetos de massa não-estelar. A formação de resíduos tem o efeito indireto de diluir o meio interestelar, levando a um enriquecimento mais lento deste e a um bom ajuste de diversos vínculos da evolução química da Galáxia, como a distribuição de anãs-G e a relação idade-metalicidade. Os efeitos da destruição do Th por reações fotonucleares em interiores estelares também foram considerados.

To analyze the care provided to tuberculosis cases in primary health care services according to the elements of the Chronic Care Model. Cross-sectional study conducted in a capital city of the northeastern region of Brazil involving 83 Family Health Strategy professionals.A structured tool adapted to tuberculosis-related care in Brazil was applied.Analysis was based on the development of indicators with capacity to produce care varying between limited and optimum. The organization of care for tuberculosis and supported self-care presented reasonable capacity.In the coordination with the community, the presence of the community agent presented optimum capacity.Partnership with organizations of the community and involvement of experts presented limited capacity.The qualification of professionals, the system for scheduling and monitoring tuberculosis in the community, and the clinical information system presented basic capacity. The capacity of the primary health care services to produce tuberculosis-related care according to the elements of the Chronic Care Model is still limited.Overcoming the fragmentation of care and prioritizing a systemic operation between actions and services of the health care network remains as a major challenge. Analisar,segundo os elementos doChronicCareModel,a produção do cuidado aos casos de tuberculose nos serviços de Atenção Primária à Saúde. Estudo transversal, realizado em capital do nordeste brasileiro, envolvendo 83 profissionais da Estratégia Saúde da Família. Aplicou-se um instrumento estruturado, adaptado para atenção à tuberculose no Brasil. A análise pautou-se na construção de indicadores, cujacapacidade para produção de cuidados variou entre limitada a ótima. A organização da atenção à tuberculose e o autocuidado apoiado apresentaram capacidade razoável. Na articulação com a comunidade, a presençadoagente comunitário de saúde apresentou capacidade ótima. A parceria com organizações da comunidade e o envolvimento de especialistas obtiveram capacidade limitada. A capacitação dos profissionais, o sistema de agendamento e monitoramento da tuberculose na comunidade e o sistema de informação clínica alcançaram capacidade básica. A capacidade dos serviços da Atenção Primária à Saúde para produção do cuidado aos casos de tuberculose,segundo os elementos doChronicCareModel,ainda é limitada.Superar a fragmentação do cuidado e priorizar um funcionamento sistêmico entre ações e serviços da rede de atenção à saúde é ainda um grande desafio.

Determinação da composição química em nebulosas planetárias na direção do anticentro galáctico

NASA Astrophysics Data System (ADS)

Costa, R. D. D.; Uchida, M. M. M.; Maciel, W. J.

2003-08-01

Existe um gradiente radial de abundâncias no disco galáctico, cujo comportamento é razoavelmente bem conhecido para distâncias galactocêntricas entre 3 e 10 kpc. Foi obtido a partir de resultados derivados de nebulosas planetárias, regiões HII e estrelas, como as estrelas quentes de tipo O, B e aglomerados abertos. Com o objetivo de investigar o comportamento deste gradiente radial na região externa do disco, conhecida como anticentro galáctico, reportamos aqui os resultados finais da análise de uma amostra de nebulosas planetárias na direção do anticentro, observadas no LNA e no ESO entre 1995 e 2000. O uso de nebulosas planetárias permite o cálculo das abundâncias de elementos traçadores da evolução química do disco como oxigênio, argônio e neônio com o uso de técnicas de espectroscopia nebular. Os resultados indicam uma distribuição de abundâncias distinta daquela encontrada na vizinhança solar, mostrando que o gradiente radial diminui sensivelmente para distâncias galactocêntricas maiores que 10 kpc. Este resultado está de acordo com os mais recentes modelos de evolução química do disco, que prevêem uma diminuição ou mesmo um desaparecimento do gradiente radial no bordo externo do disco galáctico.

López García, Z.; Malaroda, S. M.; Faraggiana, R.

Se determinan las abundancias químicas de los elementos más livianos presentes en dos estrellas CP del grupo HgMn, μ Lep y 53 Tau, utilizando espectros IUE de alta resolución y técnicas de cálculo de espectros sintéticos. Para el cálculo de las líneas se utiliza la lista mas completa de datos atómicos disponible y el programa SYNTHE. Para el cálculo de la abundancia de un elemento se comparan, para cada imagen, los perfiles observados del mayor número de líneas presentes con los perfiles calculados obtenidos por variación de las abundancias iniciales, reteniendo la abundancia para la cual el acuerdo entre las líneas observadas y calculadas es considerado visualmente el mejor. Los resultados obtenidos son comparados con los estimados por la teoría de la difusión.

Projeto do sistema anti-ressonante da fiação dos transdutores para o detector Mario Schenberg

NASA Astrophysics Data System (ADS)

Vieira, S. J.., Jr.; Melo, J. L.

2003-08-01

O detector de ondas gravitacionais Mario Schenberg está sendo projetado e construído pelo grupo Gráviton. Sua construção está ocorrendo no Laboratório de Estado Sólido e Baixas Temperaturas (LESBT) da Universidade de São Paulo, na cidade de São Paulo. Esse detector possui uma massa ressonante esférica de cobre-alumínio, com 65 cm de diâmetro, pesando aproximadamente 1150 Kg, suspensa por um sistema de isolamento vibracional, que se encontra em fase de testes preliminares. A real eficácia desse sistema, entretanto, só poderá ser comprovada quando o detector estiver aparelhado com, pelo menos, um transdutor eletromecânico de altíssima sensibilidade acoplado à massa ressonante. Neste momento, não só este sistema de isolamento vibracional será posto em teste, como o do projeto da fiação que transporta os sinais de microondas até os transdutores e destes para a pré-amplificação. Apesar dessa fiação ter sido projetada para não apresentar nenhum contato com a superfície esférica da antena, de maneira a não haver nenhuma transmissão de ruído vibracional do laboratório para esta, deve-se minimizar o ruído microfônico produzido nessa fiação por oscilações mecânicas, uma vez que ela não utiliza nenhum sistema de isolamento vibracional. Com o intuito de resolver este problema, projetamos uma estrutura, formada por pequenos cilindros conectados por barras, a qual não terá nenhuma ressonância mecânica na faixa de freqüências de interesse para detecção (3000 - 3400 Hz). Desta forma, as vibrações nessa faixa não serão amplificadas. O projeto foi feito usando iterativamente, de maneira a otimizar os resultados obtidos, o programa de elementos finitos Msc/Nastran. Através de simulações feitas neste programa, determinamos os parâmetros geométricos ideais a serem utilizados, os quais proporcionam a maior região espectral de interesse livre de ressonâncias.

This paper describes the development process of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines) based on an integrated approach to pharmaceutical services, science, technology and innovation. It starts by contextualizing health and development in Brazil and features elements of the National Policy for Science, Technology and Innovation in Health in Brazil and the National Policy for Pharmaceutical Services. On presenting pharmaceutical policy guidelines, it stresses the lack of nationwide data. This survey, commissioned by the Brazilian Ministry of Health, has two components: household survey and evaluation of pharmaceutical services in primary care. The findings point to perspectives that represent, besides the enhancement of public policy for pharmaceutical services and public health, results of government action aimed at developing the economic and industrial health care complex to improve the health conditions of the Brazilian population. RESUMO O artigo apresenta o processo de construção da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamento a partir de uma concepção integradora da Assistência Farmacêutica, Ciência, Tecnologia e Inovação. Inicia-se contextualizando a saúde e o desenvolvimento no País e apresenta elementos da Política Nacional de Ciência Tecnologia e Inovação em Saúde no Brasil e da Política Nacional de Assistência Farmacêutica. Ao apresentar as diretrizes das Políticas Farmacêuticas, destaca-se a carência de dados de abrangência nacional. A presente pesquisa, encomendada pelo Ministério da Saúde, foi estruturada em dois componentes: inquérito domiciliar e avaliação dos serviços de assistência farmacêutica na atenção básica. As perspectivas dos resultados representam, além do incremento das políticas públicas farmacêuticas e de saúde pública, resultados de ações governamentais voltadas ao desenvolvimento do complexo econômico-industrial da saúde, visando a melhoria das condições de saúde da população brasileira.

Resumen El protocolo de un ensayo clínico es la base para planificar, ejecutar, publicar y evaluar el ensayo. Sin embargo, los protocolos y las guías que existen para su elaboración varían enormemente en cuanto a su calidad y contenido. En este artículo se describe la elaboración sistemática y el alcance de la Declaración SPIRIT 2013 (denominada así por la sigla en inglés de Standard Protocol items: Recommendations for Interventional Trials o Elementos estándares de un protocolo: recomendaciones para los ensayos de intervención), una guía en la que se establecen los contenidos mínimos que debe tener el protocolo de un ensayo clínico. La lista de comprobación de la declaración SPIRIT, que consta de 33 elementos, se aplica a los protocolos de todos los ensayos clínicos y se centra más en el contenido que en el formato. En esta lista se recomienda hacer una descripción completa de lo que se ha planificado, aunque no se establece cómo diseñar o ejecutar un ensayo. Al brindar orientación sobre los contenidos fundamentales, las recomendaciones SPIRIT procuran facilitar la redacción de protocolos de alta calidad. El cumplimiento de las recomendaciones SPIRIT debería mejorar la transparencia y la exhaustividad de los protocolos de los ensayos en beneficio de los investigadores, los participantes, los pacientes, los patrocinadores, los financiadores, los comités de ética de la investigación o las juntas de revisión institucionales, los revisores, las revistas biomédicas, los registros de ensayos, los formuladores de políticas, los organismos reguladores y otras partes interesadas clave.
