    Full Text Available Durante as pesquisas de campo em arqueologia, pesquisadores vêm constatando uma crescente apropriação e ressignificação dos vestígios arqueológicos pelas comunidades locais, não só como testemunhos da sua história, mas também como elementos importantes nas demandas pelo reconhecimento de territórios e melhorias de condição de vida. Tendo em vista esta demanda, os arqueólogos têm discutido estratégias metodológicas participativas e colaborativas como alternativas para uma maior interação com os interlocutores, de forma que sejam beneficiados ambos lados interessados na pesquisa. Situado neste contexto, o presente artigo busca refletir sobre estas metodologias a partir da experiência de pesquisa na Comunidade Quilombola de Cinco Chagas do Matapi,Amapá. Em especial, são abordados aspectos caros à prática da etnografia no que diz respeito a relação do pesquisador com os interlocutores, como a relação de alteridade, dialogia e autoridade. Estas reflexões estão relacionadas, também, à metodologias educativas alternativas, onde as diferentes formas de transmissão do conhecimento local são veículos importantes para entendermos os diferentes significados dos vestígios arqueológicos para as comunidades, bem como são essenciais para uma relação de comunicação mais inclusiva entre pesquisador e interlocutores.

    Paulo José Carvalho da Silva

    Full Text Available Propõe-se analisar as noções de dor enquanto paixão presente em alguns escritos expressivos do pensamento pré-cartesiano e da medicina anterior às especializações contemporâneas. Em suma, a dor seria uma paixão própria do humano, manifestando-se no corpo e na alma, sempre referida ou misturada ao prazer, seu contrário por definição. Propõe-se também um breve paralelo com o pensamento freudiano sobre a dor.

    Full Text Available A crescente expansão urbana vem interferindo significativamente na distribuição de áreas verdes nas cidades; essas têm a função de aprimorar a saúde, melhorando a qualidade de vida das pessoas. Objetivo: caracterizar as áreas verdes existentes na zona urbana do município e identificar potencialidades, enquanto ambiente para promoção da saúde. Método: estudo quali-quantitativo e descritivo, realizado na cidade de Santo Ângelo/RS. Foram caracterizadas cada uma das áreas verdes públicas urbanas (praças existentes no município, através de levantamento da vegetação arbórea, além de investigar a existência de plantas medicinais. Para a classificação dos vegetais, foram utilizadas bibliografias já existentes. Quanto à constatação das plantas autorizadas pelo SUS, realizou-se uma busca no site da Secretaria Nacional da Saúde, para a posterior verificação. Resultados e Considerações Finais: constatou-se que, na cidade de Santo Ângelo/RS, existem 8 (oito áreas verdes públicas, onde observou-se a existência de um número menor de espécies nativas em relação às exóticas. O número total de espécies existentes em cada praça varia de 14 a 26; para as espécies nativas, este número encontra-se entre 4 a 15, enquanto que para as espécies exóticas oscila de 8 a 14. Ainda foram encontradas diversas espécies arbóreas que apresentam potencial medicinal, sendo estes os mais variados. Dentre as 58 espécies encontradas algumas estão citadas na lista de plantas medicinais de interesse do Sistema Único de Saúde (SUS, como é o caso da Bahuinia Variegata, Eugenia uniflora, Persea americana e Psidium guajava, que auxiliam na promoção da saúde.

  6. A enfermagem enquanto disciplina, profissão e trabalho

    Directory of Open Access Journals (Sweden)

    Denise Pires

    Full Text Available Ensaio com objetivo de articular aspectos teórico-conceituais de profissão, disciplina e trabalho contribuindo para a reflexão acerca do saber disciplinar e da prática profissional de enfermagem exercida no contexto do trabalho coletivo em saúde. Resgata conceitos da teoria sociológica e da epistemologia para analisar a enfermagem no cenário da ciência, da sociologia das profissões e da teorização sobre processo de trabalho em saúde. Argumenta que a enfermagem tem atributos de uma profissão e de uma disciplina científica, e que os limites da prática precisam ser contextualizados histórica e socialmente. Conclui que a enfermagem, enquanto pratica social e disciplina, enfrenta desafios científicos e políticos demandando um processo permanente de construção.

  7. Corpocidade: arte enquanto micro-resistência urbana

    Directory of Open Access Journals (Sweden)

    Fabiana Dultra Britto

    2009-08-01

    Full Text Available Partimos de uma crítica à atual espetacularização das cidades e propomos a necessidade de restituir o caráter político do espaço público por meio da valorização da experiência corporal das cidades, apresentando a idéia de corpografia como uma possibilidade de micro resistência a esse processo segregador e apolítico. O espaço público, se reconhecido, por excelência, como locus do conflito, inclui agentes e mobiliza agenciamentos muito mais diversos e contraditórios do que se desejaria ou se costuma identificar. Enquanto a arte, se reconhecida como locus da experiência, promove percepções espaço-temporais muito mais complexas do que sugerem os efeitos moralizadores e individualistas normalmente atribuídos à contemplação cenográfica.

    2001-04-01

    SCK-CEN's research and development programme on instrumentation involves the assessment and the development of sensitive measurement systems used within a radiation environment. Particular emphasis is on the assessment of optical fibre components and their adaptability to radiation environments. The evaluation of ageing processes of instrumentation in fission plants, the development of specific data evaluation strategies to compensate for ageing induced degradation of sensors and cable performance form part of these activities. In 2000, particular emphasis was on in-core reactor instrumentation applied to fusion, accelerator driven and water-cooled fission reactors. This involved the development of high performance instrumentation for irradiation experiments in the BR2 reactor in support of new instrumentation needs for MYRRHA, and for diagnostic systems for the ITER reactor.

    Full Text Available Este artigo pretende discutir alguns trechos do primeiro volume da obra literária de Marcel Proust Em busca do tempo perdido: No caminho de Swann, relacionando-os à psicanálise. Lembremos que tanto Proust como Freud deram uma atenção especial ao adormecer, ao devaneio, e, de certa forma, inauguraram um novo modo de escrita. Quiçá possamos dizer que, enquanto Proust buscava uma gramática da existência, Freud trabalhava em uma gramática do inconsciente. Como fundamentação teórica deste artigo, utilizaremos principalmente o escritor e psicanalista Phillipe Willemart.

    Full Text Available A raíz de los cambios constitucionales en Venezuela (1998-2000, ha habido también cambios en la configuración institutional del gobierno de la ciudad de Caracas, capital del país. Destaca el surgimiento legal y formal de un ‘distrito metropolitano’ como nivel intermedio de gobierno. En el ensayo se presentan las razones y antecendentes de esta nueva figura institucional, pasando por las formas de coordinación que surgieron en el período 1989-1999. Finalmente se evalúa la contribución cualitativa que la ‘alcaldía metropolitana’ agrega a la gestión urbana. Se concluye que los problemas de coordinación metropolitana aún no han sido resueltos y que el Distrito Metropolitano es, hasta el momento, una nueva jerarquía que agrega poca capacidad para coordinar y se alínea más bien dentro del contexto de la lucha intergubernamental por el poder en la ciudadWithin the constitutional changes in course in Venezuela (1998-2000, there have been important changes in the institutional framework of the government of the capital city of Caracas. The ‘Metropolitan District’ is a new legal and formal addition as an intermediate level of government. In this paper the reasons and antecedents are presented, going through the coordination arrangements practised in the period 1989-1999. Finally, an evaluation is made of the qualitative contribution of the ‘metropolitan mayor office’ adds to urban management in Caracas. It is concluded that the problems of metropolitan coordination are not yet solved, and that the Metropolitan District is -until now, a new hierarchy that brings little coordination capacity-. It is more an instrument in the intergovernmental struggle to gain political power in the city

    Full Text Available Apresenta a hemeroteca e as práticas inerentes à mesma, de modo a buscar a compreensão de contextos e processos relacionáveis à construção dos fluxos informacionais elaborados a partir de tais conjuntos. Subjacente a essa proposta inicial teve-se a ambição de destacar os etnotextos, dentro de uma linguagem jornalística ancorada por ‘formações de discursos’ e ‘discursos’, por Michel Foucault. Nesse processo, o presente trabalho tem a finalidade de registrar o referencial teórico para a nossa reflexão sobre o papel da hemeroteca enquanto espaço de memória, preservação e acesso ao conhecimento, na tentativa de compreender e reconstituir a maneira pela qual o espaço informacional se configurou no passado. A pesquisa possibilitou verificar a importância dos acervos das hemerotecas como fonte de pesquisa e sua constituição como lugar de memória.

  17. Análise de bases de dados e termos de busca para estudos bibliométricos e monitoramento científico em nanocelulose

    Directory of Open Access Journals (Sweden)

    Douglas Henrique Milanez

    2014-12-01

    Full Text Available O presente estudo objetiva selecionar bases de dados e analisar termos de uma expressão de busca com vistas ao monitoramento científico da nanocelulose. Esse nanomaterial destaca-se por ser sustentável e de grande importância para o contexto científico brasileiro e mundial. O método de seleção envolve a escolha de bases bibliográficas pertencentes à subárea de Engenharia de Materiais e Metalúrgica, do Portal de Periódicos Capes/MEC, e a aplicação de critérios pertinentes ao monitoramento científico. Para a expressão de busca, analisa-se o papel de cada termo separadamente. Os resultados mostram que bases multidisciplinares possuem respostas similares aos critérios de seleção, enquanto bases específicas divergem consideravelmente. Constata-se que publicações com os termos de busca com o radical “nano” crescem apenas a partir de 2001. Conclui-se que a sistematização de seleção e análise proposta gera insights e contribuições para o avanço do monitoramento científico em áreas complexas, emergentes e interdisciplinares, e, sobretudo, em nanocelulose.

    Full Text Available Celebrando os 100 anos da publicação de Em busca do tempo perdido, de Marcel Proust, é feita uma leitura de algumas relações entre esse clássico da literatura mundial e o pensamento arquitetônico, à luz da prática que se ensina na FAUUSP. A importância das inovações estilísticas de Proust é vista por reflexos no pensamento da Arquitetura brasileira, ao aceitar-se o papel dessa arte como linguagem do mundo que nos cerca. A imbricação de tempo e espaço permite a transposição da busca da reminiscência para a procura dos espaços de fruição da Arquitetura moderna.

    2015-12-01

    Full Text Available Resumo Este texto trata de uma parcela da juventude brasileira contemporânea que tem vivenciado singularidades no processo de transição para a vida adulta ocasionadas pelas migrações internacionais. São jovens moradores de um município rural marcado pelo transnacionalismo. Nosso objetivo é problematizar a condição juvenil nesse contexto, buscando evidenciar os elementos empíricos do transnacionalismo e sua influência na vida dos jovens, na transição para a vida adulta e na busca de reconhecimento. Os dados utilizados na análise são resultados de um estudo com jovens de famílias transnacionais, aqui identificados como filhos da migração. O estudo foi desenvolvido entre 2009 e 2013 por meio de uma etnografia, utilizando como principais formas de coleta de dados a observação direta e participante. A pesquisa de campo foi desenvolvida durante oito meses, em um município rural da região mineira de Governador Valadares, quando também foram aplicados questionários e entrevistas individuais e coletivas. Os resultados apresentados neste artigo evidenciam: as principais características do transnacionalismo nesse local de origem das migrações internacionais; aspectos da condição juvenil, das famílias transnacionais, da transição para a vida adulta e a busca dos jovens por ser alguém na vida, compreendida como expressão da busca por reconhecimento.

Os dados, obtidos através de entrevistas com inscritos no Programa Primeiro Emprego/RS, revelam que o desemprego afeta os processos de filiação social dos jovens e provoca uma produção de subjetividade marcada pelo sofrimento decorrente do aplacamento da vontade de potência.

  1. DE PROUST A BARTHES: A BUSCA PELA LITERATURA

    Directory of Open Access Journals (Sweden)

    Carla Cavalcanti e Silva

    2015-12-01

    Full Text Available Em seu ensaio "Durante muito tempo, fui dormir cedo", publicado em o Rumor da língua, Barthes ressalta uma das características mais importantes da obra proustiana: não se trata nem de Romance, nem de Ensaio, mas de uma terceira forma. Essa forma seria a única possível a dar estrutura ao romance proustiano, que destaca, dentre outros elementos, a busca do próprio narrador por tornar-se escritor. Ao discorrer sobre essa nova lógica proustiana, Barthes se identifica com Marcel Proust, pois naquele momento, o crítico busca uma nova forma de escrever (a literatura tendo como ponto de partida seu estado de luto, ou para usarmos um termo barthesiano, de acedia. O intuito desta comunicação é percorrer os escritos barthesianos que discorrem notadamente sobre Marcel Proust para analisar a importância do escritor francês na produção crítica e na escrita de Roland Barthes. Para tanto, propomos comentar fundamentalmente as obras: Novos ensaios críticos, O rumor da língua e APreparação do romance.

    Cássio Diniz Hiro

    2013-05-01

    Full Text Available Este presente artigo tem como objetivo oferecer uma pequena contribuição ao debate acerca do processo de proletarização do docente na educação brasileira. Tornou-se comum em parte dos debatedores assinalarem que o professor não pode se caracterizar enquanto um trabalhador em educação, ou seja, como parte integrante da classe social dos trabalhadores, classificando-os enquanto membros de uma dita “classe média”. Neste artigo procuramos apontar que as transformações sócio-econômicas e o desenvolvimento do modo de produção capitalista no Brasil provocaram uma profunda metamorfose no âmbito do papel social do decente brasileiro. Para isso, apresentamos algumas análises baseadas no referencial teórico marxista, fruto das contribuições ao materialismo histórico-dialético ao legado de Marx e Engels.

  6. A sala de anatomia enquanto espaço de convívio com a morte

    Directory of Open Access Journals (Sweden)

    Sílvia Helena Valente

    Full Text Available Durante o percurso de um programa de Iniciação Científica a autora teve sua atenção direcionada para a sala de anatomia, enquanto espaço acadêmico importante na formação dos profissionais de saúde. O estudo teve como proposta compreender o primeiro contato que estudantes da área médica e de enfermagem têm com a morte nessa sala e foi conduzido segundo a metodologia de investigação fenomenológica. Foram obtidos depoimentos dos estudantes quando cursavam a disciplina de Anatomia. A análise dos dados evidenciou sua grande preocupação em se apropriar dos conhecimentos acerca das peças anatômicas, focalizadas enquanto fragmentos de um corpo biológico, em detrimento de uma visão global do corpo humano. Nesse sentido, muitos relegam sentimentos de medo e tristeza, adaptando-se rapidamente com vistas ao aprimoramento técnico científico. O estudo atenta para a necessidade de se utilizar esse espaço acadêmico para discussões sobre a morte como via de acesso à uma assistência humanista por parte destes profissionais.

  7. Em Busca de Uma Experiência Extraordinária em Serviços de Restaurante

    Directory of Open Access Journals (Sweden)

    Maria de Lourdes de Azevedo Barbosa

    2012-11-01

    Full Text Available O artigo tem como objetivo propor um esquema teórico para melhor compreender como a oferta de serviços oferecidos pelos restaurantes podem passar de experiências ordinárias (utilitárias a experiências extraordinárias (hedônicas. Busca-se entender o processo de criação de uma experiência e conhecer o que leva a experiência a ser considerada como extraordinária pelo consumidor, enquanto processo de formação dinâmico. Essa abordagem pode contribuir para a obtenção de conhecimentos que deverão colaborar para enriquecer a pesquisa sobre comportamento de consumo no âmbito do setor de alimentação, na medida em que procura relativizar o aporte do modelo pessoa-objeto-situação, integrando as vantagens das relações durante a experiência de compra, em função do tipo de consumidor e do lugar da venda. O esquema teórico apresentado fornece uma visão holística do processo da experiência em serviços de restaurante e demonstra que, para que este possa ser considerado como extraordinário, é preciso existir uma interação entre o que é ofertado e a vivência do consumidor durante o processo de aquisição de um serviço.

  8. CONSTRUÇÃO DE IDENTIDADE(S NA VELHICE: OS TERRITÓRIOS ENQUANTO MARCOS IDENTITÁRIOS

    Directory of Open Access Journals (Sweden)

    Marcia Regina Medeiros Veiga

    Full Text Available RESUMO Este artigo tem por objetivo refletir sobre o contributo específico dos territórios - a casa, a rua, o entorno - enquanto referência fundamental na construção identitária de pessoas idosas. Nossa base reflexiva foi construída a partir de observações e descrições do território conhecido como "Alta", no casco histórico de Coimbra, Portugal; entrevistas semiestruturadas, com 12 de seus residentes; e com notas de campo, sistematizadas num diário de bordo da pesquisa, construído para o efeito. A construção identitária de grande parte das pessoas idosas encontra-se profundamente ancorada nos territórios onde vivem, principalmente quando estas pessoas residem há muito tempo em um mesmo espaço geográfico, no qual vivenciam uma parte muito substantiva do seu cotidiano. Esta centralidade é, ainda, reforçada quando apresentam mobilidades reduzidas ou condicionadas, quer pelas dificuldades de acessibilidade dos próprios territórios, quer por limitações pessoais, iniciadas e/ou acentuadas na velhice.

    Engelmann Arno

    1997-01-01

    Full Text Available No conhecimento científico atual, duas ocorrências são autênticas: (1 o desenvolvimento rápido da ciência empírica e (2 o uno e momentâneo da consciência. Denominei essa consciência de consciência-imediata. Em toda a aquisição de um conhecimento científico empírico ou natural, passo de uma observação individual e momentânea a um universo coletivo e temporal. É a alteração de uma verdade absoluta por um conhecimento probabilístico. Sete hipóteses básicas são apresentadas para permitir o conhecimento desse universo probabilístico. Na descrição desse universo, opto por uma explicação emergentista, isto é, uma explicação evolucionista em termos de níveis crescentes. Há a explicação presente dos vários níveis, mas, ao mesmo tempo, há a interação causal entre estes mesmos níveis. Portanto, o universo é um só. Na maioria dos animais há um nível de organismo, o nível que abarca o animal como um todo. No organismo dos seres humanos e de muitos outros animais, há uma pequena parte que pode conhecer-se a si mesma. Essa parte denominei de consciência-mediata. A consciência-mediata pode ser constituída pelo passado do próprio observador, consciência-mediata-do-observador, ou ser parte do organismo de outras pessoas ou outros animais não-humanos, consciência-mediata-de-outros. A consciência-mediata-de-outros pode ser pesquisada da mesma forma como quaisquer outras partes dos animais. A consciência-mediata-de-outros é uma das partes do universo em relação à qual há uma busca contínua.

  10. A GESTÃO DA CRIATIVIDADE ENQUANTO FONTE DE INOVAÇÃO EM UMA PEQUENA EMPRESA DA ALTA MODA

    Directory of Open Access Journals (Sweden)

    Ana Sílvia Rocha Ipiranga

    2011-06-01

    Full Text Available O cenário atual apresenta novos desafios, como uma maior independência dos consumidores, o proliferar dos concorrentes e o acirramento da competição, e por conseqüência, uma constante necessidade de inovação e uma adequada gestão da marca e da empresa. Este processo é indiscutível e ininterrupto nas empresas do sistema da moda, já que este setor tem como diferencial a cultura da criatividade e a necessidade de inovação contínua dos produtos e dos processos, caracterizando a essência da moda. Nesse contexto, o presente trabalho teve como objetivo analisar a gestão da criatividade enquanto fonte de inovação em uma pequena empresa de alta moda, por meio de um estudo de caso. Concluiu-se que para a compreensão da gestão da criatividade em uma pequena empresa da alta moda devem-se evidenciar necessariamente diversos e diferentes contextos, entre estes: o do indivíduo criativo, do grupo idealizador, destacando a posição do líder por representar a figura impulsionadora da criatividade coletiva e o dos processos de gestão adotados. As narrativas analisadas evidenciaram, ainda, que a idealização da inovação passa pelas idéias criativas das pessoas que souberam imprimir uma capacidade de inovação contínua e criaram uma forte atração de mercado para o produto.

    Full Text Available O presente estudo pretende averiguar como o Direito da Criança e do Adolescente estabelece estratégias de ação no sistema de garantias de direitos para a prevenção e erradicação do trabalho infantil, notadamente quanto às políticas públicas. Neste trabalho abordar-se-á o Serviço de Convivência e Fortalecimento de Vínculos para Adolescentes e Jovens de 15 a 17 anos (Projovem Adolescente, enquanto política pública efetiva e impactante para recuperar o desenvolvimento humano de jovens explorados pelo trabalho precoce. A técnica de pesquisa utilizada no decorrer da pesquisa foi a bibliográfica (artigos e livros e o método utilizado foi o hipotético-dedutivo. Ao longo do trabalho é possível constatar que a integração entre os programas sociais, característica marcante do Projovem Adolescente, tem se mostrado uma ferramenta interessante e eficaz no combate à exploração da mão de obra de crianças e adolescentes. Contudo, para garantir maior abrangência das políticas públicas direcionadas à infância ainda é necessária uma colaboração mais eficaz entre família, Estado e sociedade, conforme preconiza o art. 227 da Constituição Federal.

    Leonardo de Sousa Fortes

    Full Text Available RESUMO Introdução: Parece que a busca pela muscularidade pode ter relação com os transtornos alimentares (TA em atletas do sexo masculino. Todavia, de acordo com nosso conhecimento, não existem estudos sobre esse tema. Objetivo: Analisar a relação da busca pela muscularidade e estado de humor com os transtornos alimentares nessa população. Métodos: Participaram do estudo 112 competidores de diversas modalidades esportivas, pertencentes a federações do sudeste brasileiro. Utilizou-se o Eating Attitudes Test (EAT-26, Drive for Muscularity Scale (DFM e a Escala de Humor de Brunel (BRUMS para avaliar, respectivamente, os comportamentos alimentares de risco de TA, a busca pela muscularidade e o estado de humor. Resultados: Os achados dos modelos de regressão hierárquica não demonstraram relação da busca pela muscularidade (p > 0,05 e do estado de humor (p > 0,05 com os transtornos alimentares. Todavia, os resultados indicaram diferença de busca pela muscularidade em razão das classificações do EAT-26 (p 0,05. Conclusão: Concluiu-se que tanto o estado de humor quanto a busca pela muscularidade não se relacionaram com os transtornos alimentares em atletas do sexo masculino.

    Carlos Eduardo Pimentel

    Full Text Available Este estudo objetivou conhecer a correlação entre preferência musical e busca de sensações, testando modelos de mediação e moderação. Participaram 279 estudantes do ensino médio, com média de idade de 17 anos e igualmente distribuídos por sexo, que responderam a Escala de Preferência Musical, o Inventário de Arnett de Busca de Sensações e questões demográficas. Observou-se correlação da preferência por estilos musicais alternativos (positiva, como, por exemplo, rock, música eletrônica e convencional (negativa, como, por exemplo, música clássica, música religiosa com o fator intensidade de busca de sensações. Constatou-se também que as relações entre o fator novidade e os estilos alternativos e convencionais foram mediadas pela busca por intensidade. Testou-se a moderação da busca por novidade na relação entre intensidade e música alternativa, que não foi confirmada. Tais resultados foram discutidos com base na literatura sobre correlatos da busca de sensações, e sugere-se estudos que contribuam para entender seu efeito na preferência musical.

  14. MBAs: cinco discursos em busca de uma nova narrativa

    Directory of Open Access Journals (Sweden)

    Thomaz Wood Jr

    Full Text Available A indústria do management evoluiu significativamente no Brasil, desde os anos 1990, disseminando ideias e modelos de gestão. O fenômeno despertou o interesse de pesquisadores, que desenvolveram estudos sobre seus "pilares": as empresas de consultoria, a mídia de negócios, os gurus de gestão e as escolas de negócios - este último, objeto de estudo neste trabalho. Nas últimas décadas, multiplicaram-se no Brasil os programas de pós-graduação em formação gerencial: os chamados MBAs. Nos Estados Unidos e na Europa, tais programas têm sido alvo de escrutínio e de estudos científicos de natureza reflexiva e crítica. No Brasil, entretanto, poucos estudos foram realizados a respeito. Este artigo almeja preencher essa lacuna. Para isso, identificamos e apresentamos os discursos mais salientes produzidos sobre tais cursos: o discurso da crítica instrumental, o discurso da defesa instrumental, o discurso crítico de emancipação e o discurso da redenção da mídia de negócios. Além disso, também apresentamos o discurso dos alunos. Para isso, realizamos uma pesquisa com alunos de três programas brasileiros e captamos suas percepções. Concluímos que MBA pode ser visto como um campo institucional aberto, no qual diferentes agentes empregam distintas estratégias discursivas, de acordo com suas perspectivas ontológicas e seus interesses. Observamos que há pouca interação ou disputa direta entre os discursos. Entretanto, podemos identificar elementos para uma renovação da "narrativa do MBA". A nova narrativa tem como personagem um indivíduo socialmente consciente e responsável, dotado de uma ambição de mudança pessoal e profissional e que aspira a uma posição sênior de liderança ou, alternativamente, o empreendedorismo. Esse indivíduo passa por experiências que unem teoria e prática, que compreendem contextos culturais diversos e o desenvolvimento de uma visão crítica sobre as organizações e a atividade

    Full Text Available Introdução: A busca pela "muscularidade" parece estar associada a diversas variáveis que impactam a saúde e a qualidade de vida dos sujeitos. No entanto, há uma carência de estudos sobre o construto, um baixo número de instrumentos de medida específicos para sua avaliação, além de reduzida avaliação de indivíduos do sexo masculino. Objetivo: Avaliar a busca pela "muscularidade" e associá-la a sintomas depressivos, autoestima, comportamentos de risco de transtornos alimentares e ao grau de comprometimento psicológico com o exercício físico. Métodos: Realizou-se um estudo transversal com 246 jovens adultos do sexo masculino. Foram utilizados instrumentos de autorrelato para avaliar a busca pela "muscularidade" (Drive for Muscularity Scale, autoestima (Rosenberg Self-Esteem Scale, sintomas depressivos (Beck Depression Inventory, comportamentos de risco de transtornos alimentares (Eating Attitudes Test-26 e o grau de comprometimento psicológico com o exercício físico (Commitment Exercise Scale. Foi utilizado o teste de associação de Pearson para verificar relação entre as variáveis do estudo e Análise de Regressão Linear Múltipla (forward para verificação do quanto as variáveis do estudo influenciam na busca pela "muscularidade". Resultados: A busca pela "muscularidade" esteve associada à autoestima (rpearson = 0,13; p < 0,05, aos comportamentos de risco de transtornos alimentares (rpearson = 0,20; p < 0,05 e ao grau de comprometimento psicológico ao exercício (rpearson = 0,62; p < 0,05. O grau de comprometimento psicológico com o exercício explicou 38,4% da variância total da busca pela "muscularidade", 12,3% da insatisfação com a "muscularidade" e 51,0% dos comportamentos orientados para a "muscularidade". Conclusão: A busca pela "muscularidade" está associada à baixa autoestima, aos comportamentos de risco de transtornos alimentares e, em especial, ao grau de comprometimento psicológico com o exerc

    Full Text Available Os mecanismos de busca consolidaram a pesquisa por informação na internet,sendo os mecanismos de busca acadêmicos (MBAs, hoje, os principais meios para alcançar fontes científicas, como artigos de eventos ou periódicos. Ao invés de gastar horas em uma biblioteca, os MBAs ganham em popularidade pela facilidade de automatizar uma busca e acessar inúmeras bases de dados simultaneamente. Contudo, o caráter incremental das bases de materiais científicos e dos diversos MBAs existentes impõe um desafio aos pesquisadores, que é determinar um MBA que melhor atenda aos seus anseios de pesquisa. Nesse contexto, uma análise quantitativa dos recursos providos pelos MBAs foi realizada com objetivo de determinar quais são os melhores para facilitar as buscas por conteúdo científico, considerando recursos de busca, de refinamento e auxiliares. Dentre um grupo de 40 MBAs iniciais, sete apresentaram-se com σ = 0,5 acima da média nos critérios utilizados, na seguinte ordem: 1o Web of Knowledge; 2o Engineering Village; 3o Scopus SciVerse; 4o IEEE Xplore; 5o ACM Digital Library; 6o Science Direct; e 7o Springer Link. Esses MBAs deveriam ser melhor explorados pelos pesquisadores pois tem inúmeros recursos capazes de facilitar sobremaneira e elevar a qualidade do trabalho de pesquisa.

    2015-11-01

    Full Text Available A tortura, enquanto ato de impor a terceiros sofrimentos físicos e/ou psicológicos para obtenção de respostas a questões que se deseja respondidas, sempre foi uma forma corriqueira entre os humanos. Esse ato se tornou mais danoso quando assumiu a dimensão institucionalizada por parte do leviatã. Forma usual, mas em decadência com a ocorrência do desenvolvimento social, político, econômico e jurídico do Século XX. Esse trabalho apresenta uma sucinta discussão sobre a tortura enquanto violação dos direitos humanos. Mostra que contra essa violação os organismos internacionais elaboraram convenções, normas, tratados e protocolos que visam  reduzir, quando não extinguir a pratica de atos violentos contra os direitos da humanidade, em especial, contra a vida. Relata que o Brasil assinou as convenções, mas vem apresentando uma sensível lentidão na implementação de mecanismo que efetivamente coíbam a pratica da tortura. No entanto, os mecanismos criados têm forçado ao ajustamento das normas e mecanismos internos as demandas sociais potencializados pelos foros internacionais, em particular, a Corte internacional de Direitos Humanos. A metodologia constituiu-se de uma pesquisa bibliográfica em livros e artigos sobre o tema em tela. Conclui com a constatação de que ainda irá demorar muito para o Brasil ajustar e tornar efetiva a ação dos mecanismos de combate a tortura, garantindo a plenitude dos direitos da humanidade, em especial o de não ser torturado.

    Full Text Available Resumo O artigo lança um olhar para os Guna a partir da casa de residência, espaço privilegiado de comunhão e compartilhamento de recursos. Meu objetivo é demonstrar que a residência em Gunayala movimenta uma economia doméstica dos pensamentos: os Guna dizem que a pessoa preguiçosa (wiegala não pensa nos outros (binsaed suli. Ela é considerada sunnasuli - "não é parente de verdade" ou, simplesmente, "malvada". O dom é a linguagem utilizada para dar conta das transações que ocorrem no registro da intimidade. Procuro explorar as consequências da ética da convivialidade guna no que se refere à masculinidade, na medida em que os homens são levados a pensar em sua esposa como condição de fixação e permanência na casa dos afins. O problema da troca é examinado a partir das raízes mitológicas, rituais e sociológicas da uxorilocalidade, permitindo compreender o esforço de consanguinização da afinidade nos termos de um drama residencial: o drama da aliança ou a aliança enquanto drama.

    Directory of Open Access Journals (Sweden)

    Ivan Paula Santos Machado Dantas

    2015-06-01

    Full Text Available O presente trabalho busca discutir a importância do Concerto para Violino de György Ligeti e sua relevância dentre as obras do estilo tardio do compositor. Para isso são apontadas as principais características da música de Ligeti em suas diversas fases, desde sua música textural em peças como “Atmosphères” até seu recente “Hamburg Concerto”, e as peculiaridades do que o próprio Ligeti chama de estilo “não-atonal”. Uma análise do Concerto permite, então, criar relações com as características e singularidades deste estilo tardio, tais quais a utilização de tríades fora de um contexto tonal, uso simultâneo de sistemas de afinação distintos, uso de formas tradicionais como Passacaglia e Hoquetus, e trazer um entendimento mais amplo e contextualizado da obra. A análise divide-se por movimentos do concerto e tenta mostrar aspectos diversos da construção da obra, não se fixando a uma única ferramenta analítica ou teoria. Esta análise do material, da instrumentação e da textura podem servir ao propósito da interpretação da obra.

    Every neutron scattering experiment requires the choice of a suited neutron diffractometer (or spectrometer in the case of inelastic scattering) with its optimal configuration in order to accomplish the experimental tasks in the most successful way. Most generally, the compromise between the incident neutron flux and the instrumental resolution has to be considered, which is depending on a number of optical devices which are positioned in the neutron beam path. In this chapter the basic instrumental principles of neutron diffraction will be explained. Examples of different types of experiments and their respective expectable results will be shown. Furthermore, the production and use of polarized neutrons will be stressed.

    Full Text Available O livro de Lipovetsky é um passeio sobre as novas caracterizações da leveza da vida na sociedade contemporânea. Na edição, os capítulos não foram enumerados. Mas na resenha são. O livro começa com uma boa apresentação de Juremir Machado da Silva, professor da PUC-RS, que dá uma visão panorâmica do pensamento do autor. Capítulo 1 é a introdução das hipóteses, primeiro de hipermodernidade, em seguida a hipótese sobre a busca da leveza. Capítulo 2 é sobre as transformações no padrão de consumo e no comportamento do hiperconsumidor. Capítulo 3 trata do desejo de ter um corpo jovem e saudável, o que é uma voluntária adesão à ditadura do corpo magro e esbelto. Capítulo 4 tem a análise da economia que oferta os produtos para satisfazer o desejo de leveza. Capítulo 5 é uma atualização da análise sobre moda. Capítulos 6 e 7 são sobre o impacto do crescente desejo de leveza  na arte e na arquitetura. Capítulo 8 é uma análise sobre a psicologia das pessoas que buscam a leveza como felicidade, com resultados paradoxais. Capítulo 9 é sobre como o desejo por uma vida mais livre, leve e ética afeta o comportamento dos cidadãos. A ausência de um capítulo conclusivo revela que é difícil analisar um mundo em transição. O autor limitou-se a descrever a busca da leveza como uma nova tendência, com impacto sobre comportamento dos indivíduos e a economia e política da sociedade.

    Shea, T. J.; Witkover, R. L.

    1998-12-01

    The Relativistic Heavy Ion Collider (RHIC) consists of two 3.8 km circumference rings utilizing 396 superconducting dipoles and 492 superconducting quadrupoles. Each ring will accelerate approximately 60 bunches of 1011 protons to 250 GeV, or 109 fully stripped gold ions to 100 GeV/nucleon. Commissioning is scheduled for early 1999 with detectors for some of the 6 intersection regions scheduled for initial operation later in the year. The injection line instrumentation includes: 52 beam position monitor (BPM) channels, 56 beam loss monitor (BLM) channels, 5 fast integrating current transformers and 12 video beam profile monitors. The collider ring instrumentation includes: 667 BPM channels, 400 BLM channels, wall current monitors, DC current transformers, ionization profile monitors (IPMs), transverse feedback systems, and resonant Schottky monitors. The use of superconducting magnets affected the beam instrumentation design. The BPM electrodes must function in a cryogenic environment and the BLM system must prevent magnet quenches from either fast or slow losses with widely different rates. RHIC is the first superconducting accelerator to cross transition, requiring close monitoring of beam parameters at this time. High space-charge due to the fully stripped gold ions required the IPM to collect magnetically guided electrons rather than the conventional ions. Since polarized beams will also be accelerated in RHIC, additional constraints were put on the instrumentation. The orbit must be well controlled to minimize depolarizing resonance strengths. Also, the position monitors must accommodate large orbit displacements within the Siberian snakes and spin rotators. The design of the instrumentation will be presented along with results obtained during bench tests, the injection line commissioning, and the first sextant test.

    2011-12-01

    Full Text Available O debate sobre a problemática do ensino médio se intensificou. Não se trata de um debate novo. Porém, nestes últimos anos, ganhou novo fôlego, repercutindo inclusive nos meios de comunicação de massa. No intuito de contribuir para este debate, o texto traz informações de caráter histórico e considerações teóricas. Defende a tese de que o trabalho é o princípio educativo geral de todo o sistema escolar. A especificidade pedagógica do ensino médio decorre do momento vivido pelo jovem em busca de sua definição moral, intelectual e social. Por ser a fase final do ensino básico, é de caráter formativo não profissionalizante. A atual apologia e expansão da profissionalização precoce é uma declaração da falência e do abandono do ensino médio público, humanista, "culturalmente desinteressado", destinado a preparar dirigentes.

    2013-12-01

    Full Text Available O estudo busca estabelecer os fundamentos ontológicos do pensamento de Vygotsky, indicando que a construção teórica erigida pelo e autor está centrada no trabalho, como o complexo que deu origem ao homem como ser social. Tal postulado seria consistente com os princípios do marxismo recuperado por Lukács como uma ontologia do ser social, superadora da tradição metafísica e idealista, firmando, nesse sentido, o caráter radicalmente histórico da essência humana. Apontam-se os equívocos fundamentais operado pelo neovygotskianismo, o qual, tratando as categorias vygotskianas da linguagem, cultura e interação apartadas do princípio marxiano do trabalho, acaba por isolar Vygotsky do campo ontológico e, por extensão, do projeto socialista. Reafirma-se, por fim, que, não obstante a explícita relevância atribuída à dimensão metodológica do marxismo, está pressuposto na obra de Vygotsky, o substrato ontológico sobre o qual se funda o método de Marx.

    Full Text Available O presente artigo tem como temática a abordagem dos Direitos Humanos, de modo a demonstrar como a visibilidade histórica dos atos deflagrados pelas gerações passadas serve como intermédio na construção de uma sociedade mais humana e igualitária. Seu principal intuito não é trazer à baila o desespero, a amargura ou desejo de vingança, é, contudo, tratar sobre os perigos em que o ser humano pode incorrer ante sua busca desmesurada por poder. Nesse intuito é que se tratará sobre o genocídio Armênio que foi um dos primeiros atos que quase exterminou grande parcela de um povo, genocídio executado pelos atos de imposição do antigo exército Turco-Otomano; essa importância advém do fato de que esse acontecimento é pouco ou quase nada conhecido na sociedade, logo, sua existência e reconhecimento não servem para manchar a histórica da atual Turquia, mas para expor os erros passados e modificar o presente.

    1986-04-08

    An instrument is described for intercepting a carbon dioxide incident laser beam after it has energized a desired surgical target site but before it energizes material adjacent to the surgical target site. The instrument consists of: a substrate means for transmitting energy received from a laser beam away from a surgical target site, the substrate means having a high thermal conductivity and an exterior surface; a coating means for absorbing laser energy at the wavelength of a carbon dioxide laser, the coating means covering substantially the entirety of the exterior surface of the substrate means and having a high absorptivity for energy at the wavelength of the incident laser beam; and, the coating means having thickness which is large enough to provide high absorptivity but small enough to permit absorbed energy to be readily transferred to the high conductivity substrate means, and the thickness of the coating means being not greater than 0.001 inch.

    Full Text Available In the search for Justice, equity, whose roots date back to Antiquity, and the new rhetoric, proposed by Chaim Perelman in the work Ethics and Law, should be used as guiding instruments for the application of rules to specific cases. In order to assure a fair and balanced social coexistence in a society with an increasing and rapid evolution, whose legislation is not always able to follow this same evolution, it is necessary that the interpreters of the Law make use of ethical values. Justice is an aspiration of the human being who intends to find the Justice that is possible to be achieved, having the Law as a means to achieve this purpose, through the establishment of rules of conduct that assure peace and social harmony. However, Justice is an unfinished idea, since society is always in constant transformation and evolution, seeking to improve what it considers as fair and good.>Na busca da Justiça, deve-se utilizar da eqüidade, cujas raízes remontam à Antigüidade, e da lógica do razoável, proposta por Chaim Perelman na obra Ética e Direito, como instrumentos norteadores da aplicação das normas aos casos concretos. É preciso garantir um convívio social justo e equilibrado numa sociedade em crescente e acelerada evolução, porém as leis nem sempre conseguem acompanhar, então é necessário que os intérpretes do Direito se utilizem de valores éticos. A Justiça é uma aspiração do ser humano que procura encontrar aquela Justiça possível de ser concretizada, e o Direito é um vetor na consecução deste objetivo, mediante o estabelecimento de regras de conduta que garantam a paz e a harmonia social. Porém, a Justiça é uma idéia inacabada, uma vez que a sociedade está sempre em constante transformação e evolução, e busca aprimorar o que considera como justo e bom.

    Full Text Available Neste artigo apresentamos heurísticas usando o conceito da meta-heurística Busca Dispersa (BD, desenvolvidas para a solução do Problema de Roteamento de Veículos (PRV Clássico, detalhando cada uma de suas etapas básicas quando aplicadas ao problema em questão. A Busca Dispersa é um método evolutivo que combina soluções com a finalidade de criar novas soluções de melhor qualidade; ainda que apresente similaridades com os algoritmos genéticos difere dos mesmos em princípios fundamentais. Um aspecto importante da BD é formar soluções com alta qualidade para dirigir a busca a regiões promissoras. Experimentos computacionais foram realizados em quatro conjuntos de dados disponíveis na literatura. Os resultados mostram que a BD é robusta e competitiva em termos de qualidade das soluções obtidas e tempo computacional para o PRV Clássico, para os conjuntos de dados testados.In this paper we present a Scatter Search algorithm designed for the solution of the Classical Vehicle Routing Problem, giving details of each of its basic phases when applied to the routing problem. Scatter Search is an evolutionary meta-heuristic that combines solutions with the objective of obtaining new solutions of higher quality; even though there are similarities between Scatter Search and Genetic Algorithms, the two methods differ in basic principles. An important aspect of Scatter Search is to construct high quality solutions in order to direct the search to promising regions. Computational experiments were conducted using four data sets available in the literature. The results show that Scatter Search is robust and competitive in terms of both the quality of solutions and computational times, for the VRP data sets we used.

  9. Sobre a observação enquanto procedimento metodológico na análise do comportamento: positivismo lógico, operacionismo e behaviorismo radical

    Directory of Open Access Journals (Sweden)

    Alexandre Dittrich

    Full Text Available A Análise do Comportamento adota duas posições distintas sobre a observação enquanto procedimento metodológico. Na análise experimental, tende-se a aceitar apenas a descrição de relações funcionais entre variáveis observáveis. Na análise interpretativa, contudo, relações funcionais entre variáveis observáveis e não-observáveis são inferidas. A posição da filosofia behaviorista radical sobre a questão torna-se mais clara quando examinada a partir da influência do operacionismo sobre a Psicologia, em especial nas décadas de 30 e 40. O presente artigo propõe-se a realizar tal exame, apoiando-se na literatura dedicada ao assunto e nos escritos de Skinner. Concluiu-se que a análise de eventos privados, proposta por Skinner: (1 é de natureza interpretativa; (2 refere-se, pelo menos em parte, a eventos inobserváveis publicamente; (3 lança mão, em alguma medida, da introspecção enquanto método; (4 lança mão, em alguma medida, de inferências sobre o mundo privado do outro.

    Full Text Available Agostinho é filósofo cristão e Padre da Igreja de corrente latina. Ele contribuiu muitíssimo para a formação do pensamento cristão no Ocidente, constituin- do-se num verdadeiro Mestre do Ocidente. Agostinho investigou os aspectos fundamentais de uma pedagogia de estatuto religioso e lhe deu soluções significativas pela espessura cultural, pelo vigor teórico e pelo significado espiritual. Conhecimento e fé constituem a meta do processo educativo. A fé é um princípio, mas não um termo definitivo, isto é, um convite a empreender novas especulações, que já não serão tão só da razão, mas serão orientadas e dirigidas pela fé: Intellige ut credas. Crede ut intelligas. No De Magistro, Agostinho defende a ideia de que a ascensão a Deus é um processo de autoeducação, de crescimento interior que deve se realizar sob a direção do próprio indivíduo, da sua vontade e da sua racionalidade, capaz de corrigir o erro, de modo a purificar os olhos da mente e libertá-la da atração enganadora dos sentidos, para atingir a contemplação das realidades superiores imutáveis. Do processo autoeducativo, seguindo o método pedagógico perguntas e respostas, analisar-se-á a obra Solilóquios à luz de três objetivos principais: a Solilóquios é um falar consigo mesmo, mas não se constitui num monólogo interior de um eu fechado em sua identidade monádica, já que Agostinho articula seus pensamentos de forma coerente na busca da verdade; b Solilóquios é um diálogo em que a razão faz o papel tanto de instrutora como de discípula; c Solilóquios não é um mergulho do Eu na própria essência do ser em seu subjetivismo abstrato, mas a busca do Tu que coabita essa mesma interioridade, ou seja, constitui-se na busca do Outro de si

Para isso, utiliza-se da teoria do direito enquanto integridade de Ronald Dworkin, demonstrando que se para os crimes contra o patrimônio público o benefício é a extinção da punibilidade, então para os crimes contra o patrimônio privado deve haver pelo menos este mesmo benefício.

Este ensaio identifica essa encruzilhada como duas faces de uma mesma moeda. Para superá-la, propõe a distinção entre a comunicação como problema e a problemática do campo específico da Comunicação, o que se realiza como uma tarefa de construção de uma ontologia do processo comunicacional.

    The earliest astronomical instruments used in India were the gnomon and the water clock. In the early seventh century, Brahmagupta described ten types of instruments, which were adopted by all subsequent writers with minor modifications. Contact with Islamic astronomy in the second millennium AD led to a radical change. Sanskrit texts began to lay emphasis on the importance of observational instruments. Exclusive texts on instruments were composed. Islamic instruments like the astrolabe were adopted and some new types of instruments were developed. Production and use of these traditional instruments continued, along with the cultivation of traditional astronomy, up to the end of the nineteenth century.

    Full Text Available A presente pesquisa objetivou identificar o comportamento de busca de informação na Internet de bibliotecários e estudantes de ensino médio em oito escolas particulares dos municípios de Itajaí e Florianópolis, estado de Santa Catarina, Brasil. Este estudo entende que o desafio crítico para as escolas é possibilitar o aprendizado a partir de uma variedade de fontes de informação, pois a tecnologia, particularmente a Internet, modifica o ambiente de aprendizagem na escola. Os objetivos desta pesquisa foram averiguar como os bibliotecários compreendem o processo de busca de informação na Internet pelos estudantes e como prestam auxílio a eles, bem como averiguar como se processa a busca de informação pelos estudantes. Os instrumentos de coleta de dados utilizados na pesquisa foram um questionário aplicado a 8 bibliotecários, mais um questionário e um roteiro aplicados a 38 estudantes. A pesquisa teve abordagem quanti-qualitativa e análise de conteúdo. Emprega os pressupostos teóricos do Information Search Process de Carol Kuhlthau para investigar como os estudantes buscam a informação. As análises dos dados permitiram inferir que os bibliotecários avaliam que a busca de informação realizada pelos estudantes é um processo que desenvolvem de forma autônoma e com facilidade, que estes atingiram uma percepção mais acurada da Internet, e que são otimistas em relação à informação que recuperam, ainda que incerteza e dúvida sejam sentimentos presentes no decorrer da busca de informação.

    Hélio Afonso de Aguilar Filho

    2017-11-01

    Full Text Available RESUMO Longe de ser uma reconstrução sintética de autores e ideias, a história do pensamento econômico se apresenta mais como narrativas entrecortadas por perspectivas distintas. Uma mostra disso pode ser encontrada em Keynes, que construiu sua teoria geral ao se opor ao que no seu entendimento seria a Escola Clássica, mas que abrangia a teoria neoclássica. Apesar das objeções ao solecismo de Keynes, a história das ideias econômicas passou, sem muitas ressalvas, a ser contada incorporando sua definição. Esse artigo busca sistematizar as principais contribuições à Macroeconomia a partir de duas perspectivas analíticas distintas, a de Keynes e a convencional, sumarizada por Joan Robinson. Sustentar-se-á que as diferentes classificações operadas por estas distintas abordagens geram indefinições na análise a respeito dos aspectos coincidentes e contraditórios das diversas teorias macroeconômicas.

    Full Text Available Este artigo discute a importância da experiência na construção de novos conhecimentos, destacando a evolução histórica do conceito e o seu papel na aprendizagem, bem como no desenvolvimento de competências para buscar e usar informações para a produção de conhecimento científico. Parte do pressuposto de que, quanto mais experiência de qualidade os pesquisadores adquirirem com a busca e uso da informação, maior será o impacto no conhecimento produzido. Considera que a consciência da experiência pode ser uma forma de tornar o ser humano responsável eticamente pelo ciclo de produção científica, visto que as modificações ou transformações propiciadas pela ciência ocorrem em um mundo inseparável do ser, parte do corpo humano em que a mente se insere. Por isso, a discussão sobre experiência envolve os aspectos cognitivos e a dimensão ética de como o homem se relaciona com a natureza e a transforma.

    During the 1970s and 1980s, before synthesizers based on direct sampling of musical sounds became popular, replicating musical instruments using frequency modulation (FM) or wavetable synthesis was one of the “holy grails” of music synthesis. Synthesizers such as the Yamaha DX7 allowed users great flexibility in mixing and matching sounds, but were notoriously difficult to coerce into producing sounds like those of a given instrument. Instrument design wizards practiced the mysteries of FM instrument design.

Tem por base uma revisão da literatura especializada dos subsídios teóricos da Psicologia Positiva e da Logoterapia, segundo os quais é possível aprender a ser resiliente, como também aumentar, fortalecer e desenvolver o nível de resiliência, por meio do desenvolvimento de recursos internos, tendo em vista que os desafios que o velho encontra ao longo da vida podem ser reconhecidos como oportunidades para a adoção de decisões melhores e mais responsáveis, mantendo-se íntegro nas adversidades, não só superando-as, mas se transformando, crescendo e reinventando-se a partir das mesmas. Infere-se que a proposta de atuação do psicólogo na velhice visa à ajuda na construção conjunta de estratégias alternativas para o enfrentamento dos desafios da vida cotidiana, já que esse último estágio do ciclo de vida é marcado por inúmeras perdas nos âmbitos biopsicosociocultural, o que torna imprescindível tanto o resgate do bem-estar psicológico, como a busca de sentido de vida do indivíduo velho.

    2012-12-01

    Full Text Available O artigo é parte de minha pesquisa de pós-doutorado sobre sexualidade em mulheres idosas. O objetivo central é pensar o seguinte nó teórico: por um lado, a sexualidade tem sido alardeada como fundamental para um bom envelhecimento, por outro, torna-se um discurso normativo que associa “velhice saudável” com sexualidade, o que, além de criar a imagem de uma “idosa ideal” – aquela que tem vida sexual ativa – responsabiliza e culpabiliza as mulheres que não aderem a este modelo.

  16. Uma heurística de busca tabu simples para o problema de carregamento de paletes do produtor

    Full Text Available O problema de carregamento de paletes do produtor consiste em arranjar, ortogonalmente e sem sobreposição, o máximo número de caixas de dimensões (l,w ou (w,l, sobre um palete retangular de dimensões (L,W. Este problema vem sendo tratado com sucesso por heurísticas de blocos, onde são gerados padrões de carregamento compostos por um ou mais blocos, cujas peças possuem a mesma orientação. Uma característica desses métodos é que os padrões gerados estão limitados aos chamados padrões não-guilhotinados de primeira ordem. Neste trabalho é proposta uma abordagem baseada na incorporação de busca tabu simples (sem estruturas de memória de longo prazo em heurísticas de bloco. Partindo-se de uma solução inicial, são realizados movimentos de aumento de blocos, que resultam na diminuição, eliminação e criação de outros blocos. Resultados computacionais indicam que esta abordagem é capaz de gerar padrões ótimos de ordem superior em problemas de difícil resolução para outros métodos da literatura.The manufacturer's pallet loading problem consists in arranging, orthogonally and without overlapping, the maximum number of boxes with dimensions (l,w or (w,l onto a rectangular pallet with dimensions (L,W. This problem has been handled successfully by block heuristics, which generate loading patterns composed by one or more blocks where the pieces have the same orientation. A feature of such methods is that the patterns are limited to the so called 1st order non-guillotine patterns. In this work we propose an approach based on the incorporation of simple tabu search (without longer term memory structures in block heuristics. Starting from an initial pattern, the algorithm performs moves that increase the size of selected blocks in the current pattern; as a result, other blocks are decreased, eliminated or created. Computational results indicate that the approach is capable of generating superior order optimal patterns for

    2014-03-01

    Sterilization of endoscopic instruments is an important but often ignored topic. The purpose of this article is to review the current literature on the sterilization of endoscopic instruments and elaborate on the appropriate sterilization practices. Autoclaving is an economic and excellent method of sterilizing the instruments that are not heat sensitive. Heat sensitive instruments may get damaged with hot sterilization methods. Several new endoscopic instruments such as flexible ureteroscopes, chip on tip endoscopes, are added in urologists armamentarium. Many of these instruments are heat sensitive and hence alternative efficacious methods of sterilization are necessary. Although ethylene oxide and hydrogen peroxide are excellent methods of sterilization, they have some drawbacks. Gamma irradiation is mainly for disposable items. Various chemical agents are widely used even though they achieve high-level disinfection rather than sterilization. This article reviews various methods of endoscopic instrument sterilization with their advantages and drawbacks. If appropriate sterilization methods are adopted, then it not only will protect patients from procedure-related infections but prevent hypersensitive allergic reactions. It will also protect instruments from damage and increase its longevity.

    Bader, Rolf; Hansen, Uwe

    Signal processing techniques in acoustics address many concerns. Included are such things as wave propagation variables, amplitude considerations, spectral content, wavelength, and phase. Phase is primarily of concern when waves interact with each other, as well as with a medium, and the imposition of boundary conditions leads to normal mode vibrations. Such conditions are prevalent in all musical instruments, and thus relevant signal processing techniques are essential to both understanding and modeling the structure of musical instruments and the sound radiated.

  8. Future of radiological instrumentation

    Energy Technology Data Exchange (ETDEWEB)

    1988-08-01

    Future trends in the development of radiation protection instrumentation can be expected to be closely related to current trends in political and social activity that drive legislation, rule-making, and standard practice, with assistance provided by trends in material and electronic technology. Wide-range performance will be emphasized to arm the daily worker with instruments that routinely log background rates and, at the same time, are prepared to measure accident rates. Separate and simultaneous accumulation of data from several sensors to ensure complete coverage of the radiation types will be common. Mathematical manipulation of data will provide for summary data logging and, in some cases, solutions to integral equations to provide corrections to experimental data. Instruments will become more reliable by way of self-checking and correction. Miniaturization and large-scale integration of measuring instruments will provide some instrumentation for the people at large. To be effective, the instruments will necessarily cover a wide range and be very reliable. The net result of these several trends will provide for a widespread understanding of radiation protection and an implementation of as low as reasonably achievable among large segments of the population.

  9. [The instrument for thermography].

    Science.gov (United States)

    Hamaguchi, Shinsuke

    2014-07-01

    Thermography is an imaging method using the instrument to detect infrared rays emitted from the body surface, and to plot them as a distribution diagram of the temperature information. Therefore, a thermographic instrument can be assumed to measure the skin temperature of the diseased region. Such an instrument is a useful device for noninvasive and objective assessment of various diseases. Examination using a thermographic instrument can assess the autonomic dysfunction by measuring the skin blood flow involved with the sympathetic innervation. Thermography is useful in assisting the determination of the therapeutic effect. However, autonomic dysfunction should be confirmed correctly with the assessment of thermatome that shows abnormal thermal distribution in the region of the disease. Thermography should make noticeable the difference between the body temperature of abnormal and normal sites, and show the alteration of temperature. Monitoring using thermography is useful to determine the effect of sympathetic nerve block. If a thermographic instrument is used, it is important that examiners should understand the function of the instrument, as well as its advantages and disadvantages.

    The Aethalometer is an instrument that provides a real-time readout of the concentration of “Black” or “Elemental” carbon aerosol particles (BC or E) in an air stream (see Figure 1 and Figure 2). It is a self-contained instrument that measures the rate of change of optical transmission through a spot on a filter where aerosol is being continuously collected and uses the information to calculate the concentration of optically absorbing material in the sampled air stream. The instrument measures the transmitted light intensities through the “sensing” portion of the filter, on which the aerosol spot is being collected, and a “reference” portion of the filter as a check on the stability of the optical source. A mass flowmeter monitors the sample air flow rate. The data from these three measurements is used to determine the mean BC content of the air stream.

    2011-01-01

    Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of

    A fire at a nuclear power plant (NPP) has the potential to damage structures, systems, and components important to safety, if not promptly detected and suppressed. At Browns Ferry Nuclear Power Plant on March 22, 1975, a fire in the reactor building damaged electrical power and control systems. Damage to instrumentation cables impeded the function of both normal and standby reactor coolant systems, and degraded the operators’ plant monitoring capability. This event resulted in additional NRC involvement with utilities to ensure that NPPs are properly protected from fire as intended by the NRC principle design criteria (i.e., general design criteria 3, Fire Protection). Current guidance and methods for both deterministic and performance based approaches typically make conservative (bounding) assumptions regarding the fire-induced failure modes of instrumentation cables and those failure modes effects on component and system response. Numerous fire testing programs have been conducted in the past to evaluate the failure modes and effects of electrical cables exposed to severe thermal conditions. However, that testing has primarily focused on control circuits with only a limited number of tests performed on instrumentation circuits. In 2001, the Nuclear Energy Institute (NEI) and the Electric Power Research Institute (EPRI) conducted a series of cable fire tests designed to address specific aspects of the cable failure and circuit fault issues of concern1. The NRC was invited to observe and participate in that program. The NRC sponsored Sandia National Laboratories to support this participation, whom among other things, added a 4-20 mA instrumentation circuit and instrumentation cabling to six of the tests. Although limited, one insight drawn from those instrumentation circuits tests was that the failure characteristics appeared to depend on the cable insulation material. The results showed that for thermoset insulated cables, the instrument reading tended to drift

    A spectroelectrochemical instrument has been developed for measuring the total organic carbon (TOC) content of an aqueous solution. Measurements of TOC are frequently performed in environmental, clinical, and industrial settings. Until now, techniques for performing such measurements have included, various ly, the use of hazardous reagents, ultraviolet light, or ovens, to promote reactions in which the carbon contents are oxidized. The instrument now being developed is intended to be a safer, more economical means of oxidizing organic carbon and determining the TOC levels of aqueous solutions and for providing a low power/mass unit for use in planetary missions.

    2016-03-01

    The Integrating Nephelometer (Figure 1) is an instrument that measures aerosol light scattering. It measures aerosol optical scattering properties by detecting (with a wide angular integration – from 7 to 170°) the light scattered by the aerosol and subtracting the light scattered by the carrier gas, the instrument walls and the background noise in the detector (zeroing). Zeroing is typically performed for 5 minutes every day at midnight UTC. The scattered light is split into red (700 nm), green (550 nm), and blue (450 nm) wavelengths and captured by three photomultiplier tubes. The instrument can measure total scatter as well as backscatter only (from 90 to 170°) (Heintzenberg and Charlson 1996; Anderson et al. 1996; Anderson and Ogren 1998; TSI 3563 2015) At ARM (Atmospheric Radiation Measurement), two identical Nephelometers are usually run in series with a sample relative humidity (RH) conditioner between them. This is possible because Nephelometer sampling is non-destructive and the sample can be passed on to another instrument. The sample RH conditioner scans through multiple RH values in cycles, treating the sample. This kind of setup allows to study how aerosol particles’ light scattering properties are affected by humidification (Anderson et al. 1996). For historical reasons, the two Nephelometers in this setup are labeled “wet” and “dry”, with the “dry” Nephelometer usually being the one before the conditioner and sampling ambient air (the names are switched for the MAOS measurement site due to the high RH of the ambient air).

    In the October 1994 round of proposals at the ILL, the external biology review sub- committee was asked to allocate neutron beam time to a wide range of experiments, on almost half the total number of scheduled neutron instruments: on 3 diffractometers, on 3 small angle scattering instruments, and on some 6 inelastic scattering spectrometers. In the 3.5 years since the temporary reactor shutdown, the ILL`s management structure has been optimized, budgets and staff have been trimmed, the ILL reactor has been re-built, and many of the instruments up-graded, many powerful (mainly Unix) workstations have been introduced, and the neighboring European Synchrotron Radiation Facility has established itself as the leading synchrotron radiation source and has started its official user program. The ILL reactor remains the world`s most intense dedicated neutron source. In this challenging context, it is of interest to review briefly the park of ILL instruments used to study the structure and energetics of small and large biological systems. A brief summary will be made of each class of experiments actually proposed in the latest ILL proposal round.

    Full Text Available The theory of justice as equity from John Rawls is based in the use of two basics principles that ensure individual freedoms and reduction of social inequalities, legitimazing the existence of a democratic society. Accordingly, this principles assist in the maintenance of social peace, but often they are not enough for this, so the mediation as a public policy in the conflict¿s treatment is a mechanism helper of dialogue, solves conflicts consensually and prevents occurrence of other conflicts. So, as mediation is not the imposition of a decisión, but its construction by the parties themselves, it becomes a instrument of achieving the principles established by John Rawls, because it is based in the principles of equality and freedom.

    Calibration of NASA's Deep Impact spacecraft instruments allows reliable scientific interpretation of the images and spectra returned from comet Tempel 1. Calibrations of the four onboard remote sensing imaging instruments have been performed in the areas of geometric calibration, spatial resolution, spectral resolution, and radiometric response. Error sources such as noise (random, coherent, encoding, data compression), detector readout artifacts, scattered light, and radiation interactions have been quantified. The point spread functions (PSFs) of the medium resolution instrument and its twin impactor targeting sensor are near the theoretical minimum [~1.7 pixels full width at half maximum (FWHM)]. However, the high resolution instrument camera was found to be out of focus with a PSF FWHM of ~9 pixels. The charge coupled device (CCD) read noise is ~1 DN. Electrical cross-talk between the CCD detector quadrants is correctable to <2 DN. The IR spectrometer response nonlinearity is correctable to ~1%. Spectrometer read noise is ~2 DN. The variation in zero-exposure signal level with time and spectrometer temperature is not fully characterized; currently corrections are good to ~10 DN at best. Wavelength mapping onto the detector is known within 1 pixel; spectral lines have a FWHM of ~2 pixels. About 1% of the IR detector pixels behave badly and remain uncalibrated. The spectrometer exhibits a faint ghost image from reflection off a beamsplitter. Instrument absolute radiometric calibration accuracies were determined generally to <10% using star imaging. Flat-field calibration reduces pixel-to-pixel response differences to ~0.5% for the cameras and <2% for the spectrometer. A standard calibration image processing pipeline is used to produce archival image files for analysis by researchers.

    Netherlands Hydrological Modeling Instrument A decision support system for water basin management. J.C. Hoogewoud , W.J. de Lange ,A. Veldhuizen , G. Prinsen , The Netherlands Hydrological modeling Instrument (NHI) is the center point of a framework of models, to coherently model the hydrological system and the multitude of functions it supports. Dutch hydrological institutes Deltares, Alterra, Netherlands Environmental Assessment Agency, RWS Waterdienst, STOWA and Vewin are cooperating in enhancing the NHI for adequate decision support. The instrument is used by three different ministries involved in national water policy matters, for instance the WFD, drought management, manure policy and climate change issues. The basis of the modeling instrument is a state-of-the-art on-line coupling of the groundwater system (MODFLOW), the unsaturated zone (metaSWAP) and the surface water system (MOZART-DM). It brings together hydro(geo)logical processes from the column to the basin scale, ranging from 250x250m plots to the river Rhine and includes salt water flow. The NHI is validated with an eight year run (1998-2006) with dry and wet periods. For this run different parts of the hydrology have been compared with measurements. For instance, water demands in dry periods (e.g. for irrigation), discharges at outlets, groundwater levels and evaporation. A validation alone is not enough to get support from stakeholders. Involvement from stakeholders in the modeling process is needed. There fore to gain sufficient support and trust in the instrument on different (policy) levels a couple of actions have been taken: 1. a transparent evaluation of modeling-results has been set up 2. an extensive program is running to cooperate with regional waterboards and suppliers of drinking water in improving the NHI 3. sharing (hydrological) data via newly setup Modeling Database for local and national models 4. Enhancing the NHI with "local" information. The NHI is and has been used for many

  16. Developments in analytical instrumentation

    Petrie, G.

    The situation regarding photogrammetric instrumentation has changed quite dramatically over the last 2 or 3 years with the withdrawal of most analogue stereo-plotting machines from the market place and their replacement by analytically based instrumentation. While there have been few new developments in the field of comparators, there has been an explosive development in the area of small, relatively inexpensive analytical stereo-plotters based on the use of microcomputers. In particular, a number of new instruments have been introduced by manufacturers who mostly have not been associated previously with photogrammetry. Several innovative concepts have been introduced in these small but capable instruments, many of which are aimed at specialised applications, e.g. in close-range photogrammetry (using small-format cameras); for thematic mapping (by organisations engaged in environmental monitoring or resources exploitation); for map revision, etc. Another innovative and possibly significant development has been the production of conversion kits to convert suitable analogue stereo-plotting machines such as the Topocart, PG-2 and B-8 into fully fledged analytical plotters. The larger and more sophisticated analytical stereo-plotters are mostly being produced by the traditional mainstream photogrammetric systems suppliers with several new instruments and developments being introduced at the top end of the market. These include the use of enlarged photo stages to handle images up to 25 × 50 cm format; the complete integration of graphics workstations into the analytical plotter design; the introduction of graphics superimposition and stereo-superimposition; the addition of correlators for the automatic measurement of height, etc. The software associated with this new analytical instrumentation is now undergoing extensive re-development with the need to supply photogrammetric data as input to the more sophisticated G.I.S. systems now being installed by clients, instead

    Full Text Available Responsible business notion is more and more present in Polish economy, however the results of the research carried out in Polish business still shows a low level of CRS idea knowledge, especially in small and medium companies. Although responsible business notion is generally known, its details, ways of preparing strategy, instruments and what is more its benefits are still narrowly spread. Many business people face the lack of knowledge and information, which on one hand make it easier to spread and deepen wrong stereotypes connected with this notion and on the other hand make business people unwilling to implement CRS in their companies. The subjects of this article are examples of instruments which are responsible for realization of social responsibility strategy.

    The technology and instrumentation for neuroendoscopy are described: endoscopes (principles, designs, applications), light sources, instruments, accessories, holders, and navigation. Procedures for cleaning, sterilizing, and storing are included. The description is based on the author's own technical development and neuroendoscopic experience, published technology and devices, and publications on endoscopic surgery. The main work horses in neuroendoscopy are rigid glass rod endoscopes (Hopkins optics) due to the optical quality, which allows full high-definition video imaging, different angles of view, and autoclavability, which is especially important in neuroendoscopy due to the risk of Creutzfeldt-Jakob disease infection. Applications are endoscopy assistance to microsurgery, stand-alone endoscopy controlled approaches such as transnasal skull base, ventriculoscopy, and cystoscopy in the cranium. Rigid glass rod optics are also applicable in spinal endoscopy and peripheral nerve decompression using special tubes and cannulas. Rigid minifiberoptics with less resolution may be used in less complex procedures (ventriculoscopy, cystoscopy, endoscopy assistance with pen-designs) and have the advantages of smaller diameters and disposable designs. Flexible fiberoptics are usually used in combination with rigid scopes and can be steered, e.g. through the ventricles, in spinal procedures for indications including syringomyelia and multicystic hydrocephalus. Upcoming flexible chip endoscopes ("chip-in-the-tip") may replace flexible fiberoptics in the future, offering higher resolution and cold LED-illumination, and may provide for stereoscopic neuroendoscopy. Various instruments (mechanical, coagulation, laser guides, ultrasonic aspirators) and holders are available. Certified methods for cleaning and sterilization, with special requirements in neuroapplications, are important. Neuroendoscopic instrumentation is now an established technique in neurosurgical practice and

    This Technology Status Report describes research and accomplishments for the Instrumentation and Diagnostics (I D) Projects within the Advanced Research and Technology Development (AR TD) Program of the United States Department of Energy (DOE) Office of Fossil Energy (FE). Process understanding and control can be improved through the development of advanced instrumentation and diagnostics. The thrust of the I D Projects is to further develop existing measurement and control techniques for application to advanced coal-based technologies. Project highlights are: an inductively coupled plasma (ICP) instrument has been developed to analyze trace elements in gasification and combustion process streams. An in situ two-color Mie scattering technique with LSS can simultaneously measure the size, velocity, and elemental composition of coal particles during combustion. A high-temperature, fluorescence thermometry technique has accurately measured gas temperatures during field testing in combustion and gasification environments. Expert systems have been developed to improve the control of advanced coal-based processes. Capacitance flowmeters were developed to determine the mass flowrate, solid volume fraction, and particle velocities of coal slurries. 32 refs., 9 figs.

  7. Simulation visualization through dynamic instrumentation

    Energy Technology Data Exchange (ETDEWEB)

    Bisset, K.R.

    1998-09-01

    The goal of the instrument composition system is to allow a simulation user to dynamically create instruments as a simulation executes. Instruments can include graphical displays, data collectors, and debugging aides. Instruments are made up of small building blocks which can be easily combined into larger, more complex instruments. Through the sue of an Attribute Server (a distributed publication/subscription mechanism), the actors and instruments in a simulation can interact without direct knowledge of each other. Instead, each actor publishes the attributes which it has available. An instrument subscribes to the attributes in which it is interested, and is notified whenever the value of one of these attribute changes. An instrument can also publish attributes for use by other instruments. Since the Attribute Server is distributed, the publisher of an attribute need not execute on the same machine as the subscriber. This allows CPU intensive data visualization to execute on separate machines from the simulation, minimizing the impact on the simulation.

  8. FHR Process Instruments

    Energy Technology Data Exchange (ETDEWEB)

    Holcomb, David Eugene [ORNL

    2015-01-01

    Fluoride salt-cooled High temperature Reactors (FHRs) are entering into early phase engineering development. Initial candidate technologies have been identified to measure all of the required process variables. The purpose of this paper is to describe the proposed measurement techniques in sufficient detail to enable assessment of the proposed instrumentation suite and to support development of the component technologies. This paper builds upon the instrumentation chapter of the recently published FHR technology development roadmap. Locating instruments outside of the intense core radiation and high-temperature fluoride salt environment significantly decreases their environmental tolerance requirements. Under operating conditions, FHR primary coolant salt is a transparent, low-vapor-pressure liquid. Consequently, FHRs can employ standoff optical measurements from above the salt pool to assess in-vessel conditions. For example, the core outlet temperature can be measured by observing the fuel s blackbody emission. Similarly, the intensity of the core s Cerenkov glow indicates the fission power level. Short-lived activation of the primary coolant provides another means for standoff measurements of process variables. The primary coolant flow and neutron flux can be measured using gamma spectroscopy along the primary coolant piping. FHR operation entails a number of process measurements. Reactor thermal power and core reactivity are the most significant variables for process control. Thermal power can be determined by measuring the primary coolant mass flow rate and temperature rise across the core. The leading candidate technologies for primary coolant temperature measurement are Au-Pt thermocouples and Johnson noise thermometry. Clamp-on ultrasonic flow measurement, that includes high-temperature tolerant standoffs, is a potential coolant flow measurement technique. Also, the salt redox condition will be monitored as an indicator of its corrosiveness. Both

    This paper gives an overview of the CARMENES instrument and of the survey that will be carried out with it during the first years of operation. CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) is a next-generation radial-velocity instrument under construction for the 3.5m telescope at the Calar Alto Observatory by a consortium of eleven Spanish and German institutions. The scientific goal of the project is conducting a 600-night exoplanet survey targeting ~ 300 M dwarfs with the completed instrument. The CARMENES instrument consists of two separate echelle spectrographs covering the wavelength range from 0.55 to 1.7 μm at a spectral resolution of R = 82,000, fed by fibers from the Cassegrain focus of the telescope. The spectrographs are housed in vacuum tanks providing the temperature-stabilized environments necessary to enable a 1 m/s radial velocity precision employing a simultaneous calibration with an emission-line lamp or with a Fabry-Perot etalon. For mid-M to late-M spectral types, the wavelength range around 1.0 μm (Y band) is the most important wavelength region for radial velocity work. Therefore, the efficiency of CARMENES has been optimized in this range. The CARMENES instrument consists of two spectrographs, one equipped with a 4k x 4k pixel CCD for the range 0.55 - 1.05 μm, and one with two 2k x 2k pixel HgCdTe detectors for the range from 0.95 - 1.7μm. Each spectrograph will be coupled to the 3.5m telescope with two optical fibers, one for the target, and one for calibration light. The front end contains a dichroic beam splitter and an atmospheric dispersion corrector, to feed the light into the fibers leading to the spectrographs. Guiding is performed with a separate camera; on-axis as well as off-axis guiding modes are implemented. Fibers with octagonal cross-section are employed to ensure good stability of the output in the presence of residual guiding errors. The

    Full Text Available O artigo identifica as instâncias subjetivas do que leva o ser humano à busca por experiências de cunho espiritual e religioso. Situa a contemporânea busca religiosa e a crise de sentido que afeta a humanidade como uma busca de realização espiritual e do ser-si-próprio, diante de um mundo onde a potencialidade espiritual se encontra cada vez mais devastada. Viktor Frankl, Karl Jaspers, Paul Tillich, todos originários das contribuições da fenomenologia, são os principais autores a sustentar a reflexão em torno do tema. Frankl sustenta a ideia de um inconsciente espiritual, de uma transcendência da consciência, e Jaspers e Tillich se ocupam com a análise da “situação espiritual do nosso tempo”, uma era cujos reflexos colhemos sobremodo no terceiro milênio. Todos tratam de decifrar a intrínseca relação da não realização espiritual, da busca de um sentido do ser humano para a sua existência com a crise mais generalizada no mundo ocidental. A conclusão do texto segue na perspectiva de que a busca espiritual é inerente ao ser humano, pois se trata da realização do ser humano como ser-si-próprio no mundo. A impossibilidade de realização desta dimensão leva a uma profunda frustração existencial cujas consequências são patentes no modo de vida da humanidade na contemporaneidade.

During this time, considerable progress has been made in the development and fabrication of micromechanical gyroscopes, accelerometers, and acoustic sensors. Inertial instruments have become a worldwide research and commercial topic. Draper gyroscopes and accelerometers have been fabricated with measurement ranges from 50 to 500 deg/s and 10 to 100,000 g, respectively. In gyroscopes, stabilities are 20 deg/h in room temperature tests and 4.4 deg/h applying 0.3 degrees C thermal control. For accelerometers, less than 1 mg has been demonstrated in room temperature tests. These units have performed successfully across a temperature range of -40 to 85 degrees C, and have survived 80,000- to 120,000-g shock tests along all axes. Continuing development activities are expected to yield over an order of magnitude in performance enhancement. These micromechanical instruments are built using a silicon wafer process that results in crystal silicon structures that are anodically bonded on a Pyrex substrate that contains sensing and control electrodes. This silicon-on-glass configuration has low stray capacitance, and is ideally suited for hybrid or flip-chip bonding technology. Draper's inertial sensors incorporate excellent fabrication, however, building the silicon and Pyrex sensor chip is only one of many important contributions in a complete sensor system. Other equally important steps include: 1) electronics and application-specific integrated circuits (ASICs) 2) packaging, 3) test, and 4) modeling and analysis. This presentation focuses on sensor fabrication. Draper's accelerometers and gyroscopes and the dissolved wafer fabrication process are described. The evolution of gyro design, fabrication, and performance is summarized. Garnered through experience in both conventional and

    The Low Energy Ion Ring (LEIR) is central to the “Ions for LHC” project. Its role is to transform a serie of long low intensity ion pulses from Linac 3, into short high density pulses, which will be further accelerated in the PS and SPS rings, before injection into LHC. To do so the injected pulses are stacked and phase space cooled using electron cooling, before acceleration to the ejection energy of 72 MEV/u. This note describes different types of instruments which will be installed in the LEIR ring and transfer lines.

    Think of guitars and you think of rock and country music, or the vigorous rhythms of the gypsy flamenco, or perhaps the classical strumming of a Segovia. About the last thing you would associate with guitars is aerospace technology. Yet there is a connection. A whole family of quality guitars is an outgrowth of helicopter rotor research conducted for the military services and NASA by an aerospace contractor. These musical spinoffs, commercially available and rapidly gaining in popularity, are the Ovation guitar line, manufactured by Ovation Instruments, Inc., Bloomfield, Connecticut. Ovation Instruments is a subsidiary of Kaman Corporation, a diversified company originally formed to develop and build helicopters. A helicopter's rotor system, with thousands of moving parts, is highly susceptible to vibration. For rotor efficiency, vibration must be "dampened," or reduced. Like other helicopter builders, Kaman Corporation spent years of research toward that end. The technology thus developed, together with the availability of staff experts in vibration engineering, sparked an idea in the mind of the company's president and founder, Charles H. Karnan. A guitarist of professional caliber, Kaman reasoned that vibration-dampening technology could be turned around to enhance vibration and thereby produce a guitar with superior sound.

    The far ultraviolet (FUV) spectral range (from about 115 nm to 180 nm) is one of the most useful spectral regions for characterizing the upper atmosphere (thermosphere and ionosphere). The principal advantages are that there are FUV signatures of the major constituents of the upper atmosphere as well as the signatures of the high-latitude energy inputs. Because of the absorption by thermospheric O2, the FUV signatures are seen against a "black" background, i.e., one that is not affected by ground albedo or clouds and, as a consequence, can make useful observations of the aurora during the day or when the Moon is above the horizon. In this paper we discuss the uses of FUV remote sensing, summarize the various techniques, and discuss the technological challenges. Our focus is on a particular type of FUV instrument, the scanning imaging spectrograph or SIS: an instrument exemplified by the Defense Meteorological Satellite Program Special Sensor Ultraviolet Imager and Thermosphere Ionosphere Mesosphere Energetics and Dynamics Global Ultraviolet Imager. The SIS combines spatial imaging of the disk with limb profiles as well as spectral information at each point in the scan.

    The Q/U Imaging ExperimenT (QUIET) is designed to measure polarization in the Cosmic Microwave Background, targeting the imprint of inflationary gravitational waves at large angular scales ({approx}1{sup o}). Between 2008 October and 2010 December, two independent receiver arrays were deployed sequentially on a 1.4m side-fed Dragonian telescope. The polarimeters which form the focal planes use a highly compact design based on High Electron Mobility Transistors (HEMTs) that provides simultaneous measurements of the Stokes parameters Q, U, and I in a single module. The 17-element Q-band polarimeter array, with a central frequency of 43.1 GHz, has the best sensitivity (69 {mu}Ks{sup 1/2}) and the lowest instrumental systematic errors ever achieved in this band, contributing to the tensor-to-scalar ratio at r < 0:1. The 84-element W-band polarimeter array has a sensitivity of 87 {mu}Ks{sup 1/2} at a central frequency of 94.5 GHz. It has the lowest systematic errors to date, contributing at r < 0:01. The two arrays together cover multipoles in the range {ell} {approx} 25 -- 975. These are the largest HEMT-based arrays deployed to date. This article describes the design, calibration, performance of, and sources of systematic error for the instrument.

Com o propósito de superar pontos de estrangulamentos que limitavam a expansão do setor produtivo, o governo estadual investiu nas áreas de educação, transporte, energia, sistema de crédito e agricultura e os resultados alcançados nesse decênio se refletiram na expansão no número de salas de aulas, ginásios de esporte, qualificação de professores, tempo de estudo de alunos, implantação e reformas de rodovias, expansão da oferta de energia, criação de sistema de crédito estadual, aumento da oferta agrícola, integração de produtores rurais, entre outros. Os dados coletados revelam que ao fim desse período, Santa Catarina pode contar com melhores condições infraestruturais para participar do movimento de crescimento da economia nacional. Em consequência disso, os resultados da pesquisa de maneira geral apontam que os ideais defendidos pela corrente desenvolvimentista, ou seja, aquela que entende que o Estado é o agente responsável pela garantia da criação das condições favoráveis à expansão das atividades produtivas e, consequentemente, pelo avanço em relação aos indicadores de desenvolvimento, ficam fortalecidos.  This paper describe the result of a descriptive and exploratory study that refers to an predominantly qualitative research about the experiences of economic planning carried out by the government of Santa Catarina (Brazil during the period between 1961 and 1970 and which became known as PLAMEG I and PLAMEG II.  In order to overcome the limits to the expansion of the productive sector, the government has invested in education, transportation, energy and agriculture credit system. The results were more classrooms, gymnasiums, qualification of teachers, more highways, expanding the supply of energy and also integration of rural producers.  After this time, the State of Santa Catarina can count on better structure to participate in the movement of national economic growth. The search results show that the goals planned by the people who understand that the government is an agent that must ensure the creation of favorable conditions for the expansion of productive activities as a way to improve the development.

    Full Text Available O estudo faz uma reflexão acerca do sistema de informação de AIDS, dando visibilidade às potencialidades e limitações deste sistema no contexto atual da epidemia e numa perspectiva mais ampliada de vigilância epidemiológica. Buscou-se fazer uma descrição do sistema, considerando seus diversos componentes. Além disso, tratou-se do resultado referente ao levantamento nas fichas de notificação/investigação de AIDS no período de 1985 a 1995, e, em uma atualização da base de dados como contribuição para a qualidade do sistema. Os resultados mostraram melhora na consistência do banco de dados de AIDS, em particular das variáveis: ocupação, bairro, escolaridade e categoria de exposição, embora tenham sido identificadas limitações concretas na concepção e na estrutura do sistema para dar conta da complexidade e heterogeneidade da vigilância da AIDS. Daí ter sido apontada a necessidade de estruturação de um eficiente sistema de vigilância do HIV/AIDS, tomando-se como referência os indicadores epidemiológicos direcionados ao monitoramento e à avaliação mediante acompanhamento das mudanças no padrão epidemiológico, como da análise do impacto na morbi-mortalidade decorrente do acesso a formas mais eficientes de prevenção, aos novos tratamentos e terapêuticas.This study analyzes the Rio de Janeiro Municipal AIDS Information System, specifically the system's strengths and limitations in the epidemic's current context, from a broader perspective of epidemiological surveillance. The objective was to provide a brief description of the system, considering its different components. The authors further analyzed records pertaining to the reporting and investigation of AIDS cases from 1985 to 1995 and an update of the database as a contribution to the system's quality. The results showed improvement in the consistency of the AIDS database, particularly for the following variables: occupation, neighborhood, school, and exposure category, although the study found concrete limitations in the system's design and structure for dealing with the complexity and heterogeneity of AIDS surveillance. The study thus identified the need to construct an efficient HIV/AIDS surveillance system, based on epidemiological indicators aimed at monitoring and evaluating changes in the epidemiological pattern and analysis of the impact on morbidity and mortality resulting from access to more efficient forms of prevention and new treatments.

    1998-01-01

    The Instrument Remote Control (IRC) project ongoing at NASA's Goddard Space Flight Center's (GSFC) Information Systems Center (ISC) supports NASA's mission by defining an adaptive intranet-based framework that provides robust interactive and distributed control and monitoring of remote instruments. An astronomical IRC architecture that combines the platform-independent processing capabilities of Java with the power of Extensible Markup Language (XML) to express hierarchical data in an equally platform-independent, as well as human readable manner, has been developed. This architecture is implemented using a variety of XML support tools and Application Programming Interfaces (API) written in Java. IRC will enable trusted astronomers from around the world to easily access infrared instruments (e.g., telescopes, cameras, and spectrometers) located in remote, inhospitable environments, such as the South Pole, a high Chilean mountaintop, or an airborne observatory aboard a Boeing 747. Using IRC's frameworks, an astronomer or other scientist can easily define the type of onboard instrument, control the instrument remotely, and return monitoring data all through the intranet. The Astronomical Instrument Markup Language (AIML) is the first implementation of the more general Instrument Markup Language (IML). The key aspects of our approach to instrument description and control applies to many domains, from medical instruments to machine assembly lines. The concepts behind AIML apply equally well to the description and control of instruments in general. IRC enables us to apply our techniques to several instruments, preferably from different observatories.

    A multi-purpose instrument for measuring neutron flux, coolant flow rate, and coolant temperature in a nuclear reactor is described. The device consists essentially of a hollow thimble containing a heat conducting element protruding from the inner wall, the element containing on its innermost end an amount of fissionsble materinl to function as a heat source when subjected to neutron flux irradiation. Thermocouple type temperature sensing means are placed on the heat conducting element adjacent the fissionable material and at a point spaced therefrom, and at a point on the thimble which is in contact with the coolant fluid. The temperature differentials measured between the thermocouples are determinative of the neutron flux, coolant flow, and temperature being measured. The device may be utilized as a probe or may be incorporated in a reactor core. (AE C)

Este artigo relata três casos de óbito de bebês após o uso dessa técnica. MÉTODOS: Um total de 26 casos de engasgamento causado por aspiração de corpos estranhos nas vias respiratórias superiores e inferiores envolvendo crianças menores de 11 anos submetidas a autopsia no Departamento de Medicina Forense da Universidade da Jordânia entre 1996 e 2006 foram revisados. RESULTADOS: O uso de busca às cegas com os dedos para retirar corpos estranhos de faringe foi relatado em três bebês durante o choro. Todas as crianças eram menores de 1 ano e haviam se engasgado com grãos-de-bico, uma bola de gude e um lápis curto. A diversidade, o tamanho, a forma, e a maciez da superfície são as principais características que fazem com que esses corpos estranhos sejam mais difíceis de ser removidos com os dedos e facilitam sua entrada via respiratória.

    Full Text Available Objectives: The goal of this project was to develop the first disease-specific instrument for the evaluation of quality of life in chronic pancreatitis. Methods: Focus groups and interview sessions were conducted, with chronic pancreatitis patients, to identify items felt to impact quality of life which were subsequently formatted into a paper-and-pencil instrument. This instrument was used to conduct an online survey by an expert panel of pancreatologists to evaluate its content validity. Finally, the modified instrument was presented to patients during precognitive testing interviews to evaluate its clarity and appropriateness. Results: In total, 10 patients were enrolled in the focus groups and interview sessions where they identified 50 items. Once redundant items were removed, the 40 remaining items were made into a paper-and-pencil instrument referred to as the Pancreatitis Quality of Life Instrument. Through the processes of content validation and precognitive testing, the number of items in the instrument was reduced to 24. Conclusions: This marks the development of the first disease-specific instrument to evaluate quality of life in chronic pancreatitis. It includes unique features not found in generic instruments (economic factors, stigma, and spiritual factors. Although this marks a giant step forward, psychometric evaluation is still needed prior to its clinical use.

A partir dessa tipologia, os buscadores são exemplificados e discutidos, abarcando esse cenário de múltiplas sintaxes de indexação e busca da informação e conhecimento no ciberespaço e ao mesmo tempo construindo uma ontologia desse objeto. O ciberespaço sempre terá e trará o problema da taxonomia do conhecimento e da multiplicidade dos signos, seja em sua representação ou organização.

  18. MIKHAIL BULGÁKOV E YESHUA HA-NOTZRI: Evidências da primeira busca do "Jesus histórico" na literatura soviética

    Alexander ZHEBIT

    Full Text Available RESUMO O romance O Mestre e Margarida de Mikhail Bulgákov põe em evidência o conflito das diferentes abordagens do problema do "Jesus histórico". A referida obra do escritor e dramaturgo soviético, que se insere em um contexto político e social do stalinismo, é analisada do ponto de vista da apresentação da figura de Cristo como personagem histórica e é contemporizada com publicações sobre a religião, sob ângulos da evolução histórica da sociedade russa e soviética, na época da escrita do romance. Os núcleos separados da análise do conteúdo dos Evangelhos, segundo a narrativa de Bulgákov, ressaltando o crime, o castigo e a vingança, enfatizam a natureza humana de Cristo, seu discurso e seus sentimentos e levam a conclusões sobre uma busca do "Jesus histórico" por meio da literatura soviética.

    Full Text Available O objetivo deste estudo de caráter etnográfico foi analisar o significado da busca de tratamento por mulheres com transtorno depressivo atendidas em um Núcleo de Atenção Psicossocial do município de Santos, São Paulo, Brasil. Foram identificados, neste contexto: o tratamento da depressão no serviço (do encaminhamento ao atendimento, as noções de doença elaboradas pelas mulheres e o consumo de medicamentos. Ficaram evidentes: a banalização da depressão, a importância do psiquiatra e do uso de antidepressivos e ansiolíticos no tratamento. Os padrões encontrados de consumo dos medicamentos pelas mulheres sugerem a ocorrência de uma "toxicomania medicamentosa". O uso de medicamentos, além da ação farmacológica, possui uma ação simbólica, no sentido de conforto e cuidado. O trabalho aponta para a necessidade de se articularem o significado das experiências das mulheres e as abordagens terapêuticas da depressão na construção das políticas públicas de saúde mental.

    To improve the quantitative description of precipitation processes in climate models, the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility has been collecting observations of the drop size spectra of rain events since early in 2006. Impact disdrometers were the initial choice due to their reliability, ease of maintenance, and relatively low cost. Each of the two units deployed was accompanied by a nearby tipping bucket. In 2010, the tipping buckets were replaced by weighing buckets rain gauges. Five video disdrometers were subsequently purchased and are described in ARM’s VDIS Handbook.1 As of April 2011, three of the weighing bucket instruments were deployed, one was to travel with the second ARM Mobile Facility, and the fifth was a spare. Two of the video disdrometers were deployed, a third was to be deployed later in the spring of 2011, one was to travel with the second ARM Mobile Facility, and the last was a spare. Detailed descriptions of impact disdrometers and their datastreams are provided in this document.

    This article presents recent developments in actuated musical instruments created by the authors, who also describe an ecosystemic model of actuated performance activities that blur traditional boundaries between the physical and virtual elements of musical interfaces. Actuated musical instruments...... are physical instruments that have been endowed with virtual qualities controlled by a computer in real-time but which are nevertheless tangible. These instruments provide intuitive and engaging new forms of interaction. They are different from traditional (acoustic) and fully automated (robotic) instruments...... in that they produce sound via vibrating element(s) that are co-manipulated by humans and electromechanical systems. We examine the possibilities that arise when such instruments are played in different performative environments and music-making scenarios, and we postulate that such designs may give rise to new...

Neste estudo, argumenta-se que a combinação desses instrumentos com o uso de incentivos governamentais pode ser mais eficaz para promover essa melhoria. A questão que direcionou este estudo foi: "Quais incentivos governamentais, se implementados, seriam os mais promissores para influenciar a alta administração das organizações na melhoria da SST?". Metodologia:Na busca de respostas para essa questão foram entrevistados membros da alta administração de cinco companhias que operam 11 terminais marítimos para granéis líquidos no país. Utilizou-se um questionário contendo 43 questões que permitiu coletar informações sobre seis tipos de incentivos: flexibilização das alíquotas de contribuição do seguro acidente do trabalho (SAT, flexibilização da ocorrência das fiscalizações programadas dos ambientes e condições de trabalho, reconhecimento público em SST, publicidade negativa em SST, publicidade de dados comparativos do desempenho da SST entre organizações do mesmo segmento e estabelecimento de requisitos de SST nas licitações públicas. RESULTADOS E CONCLUSÃO: Os incentivos estudados têm potencial para exercer influência nas decisões dos entrevistados, com exceção do incentivo na forma de estabelecimento de requisitos de SST nas licitações públicas, pois essas companhias não possuem relações comerciais com o governo. Os incentivos na forma de flexibilização das alíquotas do SAT e na forma de flexibilização da ocorrência das fiscalizações programadas foram apontados como os mais promissores para promover a melhoria da SST.INTRODUCTION: Regulation and inspection have been the main government instruments to promote the improvement of occupational health and safety (OHS.

    Frontal recess dissection proposes many challenges to the surgeon. These challenges stem from its highly variable nature, small caliber, difficult visualization, and proximity to vital structures such as the skull base and orbit. As such, delicate mucosal-sparing dissection of the frontal recess with proper instrumentation is paramount to minimize scar formation and ensure patency. Here, the article explores key instrumentation in frontal recess surgery with an emphasis on hand instruments and adjunctive technologies. Copyright © 2016 Elsevier Inc. All rights reserved.

    The MISR Interactive eXplorer (MINX) software functions both as a general-purpose tool to visualize Multiangle Imaging SpectroRadiometer (MISR) instrument data, and as a specialized tool to analyze properties of smoke, dust, and volcanic plumes. It includes high-level options to create map views of MISR orbit locations; scrollable, single-camera RGB (red-greenblue) images of MISR level 1B2 (L1B2) radiance data; and animations of the nine MISR camera images that provide a 3D perspective of the scenes that MISR has acquired. NASA Tech Briefs, September 2008 55 The plume height capability provides an accurate estimate of the injection height of plumes that is needed by air quality and climate modelers. MISR provides global high-quality stereo height information, and this program uses that information to perform detailed height retrievals of aerosol plumes. Users can interactively digitize smoke, dust, or volcanic plumes and automatically retrieve heights and winds, and can also archive MISR albedos and aerosol properties, as well as fire power and brightness temperatures associated with smoke plumes derived from Moderate Resolution Imaging Spectroradiometer (MODIS) data. Some of the specialized options in MINX enable the user to do other tasks. Users can display plots of top-of-atmosphere bidirectional reflectance factors (BRFs) versus camera-angle for selected pixels. Images and animations can be saved to disk in various formats. Also, users can apply a geometric registration correction to warp camera images when the standard processing correction is inadequate. It is possible to difference the images of two MISR orbits that share a path (identical ground track), as well as to construct pseudo-color images by assigning different combinations of MISR channels (angle or spectral band) to the RGB display channels. This software is an interactive application written in IDL and compiled into an IDL Virtual Machine (VM) ".sav" file.

    The astronomically interested Duke Ernst II von Sachsen-Gotha-Altenburg (1745-1804) hired Baron Franz Xaver von Zach (1754-1832) as court astronomer in 1786. Immediatedly Zach started to make plans for instrumentation for a new observatory. But first they travelled with their instruments (a 2-foot Ramsden transit instrument, the Sisson quadrant, three Hadley sextants, two achromatic refractors and chronometers) to southern France. In Hyàres a tower of the wall around the town was converted into an observatory in 1787. For the building of the new observatory Zach had chosen a place outside of Gotha on the top of the Seeberg. The three main instruments were an 8-foot transit instrument made by Ramsden, a northern and southern mural quadrant made by Sisson and a zenith sector made by Cary, in addition an 8-foot circle made by Ramsden. By analysing the whole instrumentation of Gotha observatory, we can see a change around 1800 in the kind of instruments, from quadrants and sextants to the full circles and from the transit instrument to the meridian circle. The decline of the Gotha observatory started with the early death of the Duke in 1804 and the subsequent departure of Zach in 1806.

    2014-09-04

    Like many new fields, implementation science has become vulnerable to instrumentation issues that potentially threaten the strength of the developing knowledge base. For instance, many implementation studies report findings based on instruments that do not have established psychometric properties. This article aims to review six pressing instrumentation issues, discuss the impact of these issues on the field, and provide practical recommendations. This debate centers on the impact of the following instrumentation issues: use of frameworks, theories, and models; role of psychometric properties; use of 'home-grown' and adapted instruments; choosing the most appropriate evaluation method and approach; practicality; and need for decision-making tools. Practical recommendations include: use of consensus definitions for key implementation constructs; reporting standards (e.g., regarding psychometrics, instrument adaptation); when to use multiple forms of observation and mixed methods; and accessing instrument repositories and decision aid tools. This debate provides an overview of six key instrumentation issues and offers several courses of action to limit the impact of these issues on the field. With careful attention to these issues, the field of implementation science can potentially move forward at the rapid pace that is respectfully demanded by community stakeholders.

    2016-05-27

    Resilience benefits from the use of protective factors, as opposed to risk factors, which are associated with vulnerability. Considerable research and instrument development has been conducted in clinical settings for patients. The need existed for an instrument to be developed in a workplace setting to measure resilience of employees. This study developed and tested a resilience instrument for employees in the workplace. The research instrument was distributed to executives and nurses working in the United States in hospital settings. Five-hundred-forty completed and usable responses were obtained. The instrument contained an inventory of workplace resilience, a job stress questionnaire, and relevant demographics. The resilience items were written based on previous work by the lead author and inspired by Weick's [1] sense-making theory. A four-factor model yielded an instrument having psychometric properties showing good model fit. Twenty items were retained for the resulting Workplace Resilience Instrument (WRI). Parallel analysis was conducted with successive iterations of exploratory and confirmatory factor analyses. Respondents were classified based on their employment with either a rural or an urban hospital. Executives had significantly higher WRI scores than nurses, controlling for gender. WRI scores were positively and significantly correlated with years of experience and the Brief Job Stress Questionnaire. An instrument to measure individual resilience in the workplace (WRI) was developed. The WRI's four factors identify dimensions of workplace resilience for use in subsequent investigations: Active Problem-Solving, Team Efficacy, Confident Sense-Making, and Bricolage.

  3. Instrumental variables and Mendelian randomization with invalid instruments

    Science.gov (United States)

    Kang, Hyunseung

    Instrumental variables (IV) methods have been widely used to determine the causal effect of a treatment, exposure, policy, or an intervention on an outcome of interest. The IV method relies on having a valid instrument, a variable that is (A1) associated with the exposure, (A2) has no direct effect on the outcome, and (A3) is unrelated to the unmeasured confounders associated with the exposure and the outcome. However, in practice, finding a valid instrument, especially those that satisfy (A2) and (A3), can be challenging. For example, in Mendelian randomization studies where genetic markers are used as instruments, complete knowledge about instruments' validity is equivalent to complete knowledge about the involved genes' functions. The dissertation explores the theory, methods, and application of IV methods when invalid instruments are present. First, when we have multiple candidate instruments, we establish a theoretical bound whereby causal effects are only identified as long as less than 50% of instruments are invalid, without knowing which of the instruments are invalid. We also propose a fast penalized method, called sisVIVE, to estimate the causal effect. We find that sisVIVE outperforms traditional IV methods when invalid instruments are present both in simulation studies as well as in real data analysis. Second, we propose a robust confidence interval under the multiple invalid IV setting. This work is an extension of our work on sisVIVE. However, unlike sisVIVE which is robust to violations of (A2) and (A3), our confidence interval procedure provides honest coverage even if all three assumptions, (A1)-(A3), are violated. Third, we study the single IV setting where the one IV we have may actually be invalid. We propose a nonparametric IV estimation method based on full matching, a technique popular in causal inference for observational data, that leverages observed covariates to make the instrument more valid. We propose an estimator along with

    With the advent of microprocessors and digital-processing technologies as catalyst, classical sensors capable of simple signal conditioning operations have evolved rapidly to take on higher and more specialized functions including validation, compensation, and classification. This new category of sensor expands the scope of incorporating intelligence into instrumentation systems, yet with such rapid changes, there has developed no universal standard for design, definition, or requirement with which to unify intelligent instrumentation. Explaining the underlying design methodologies of intelligent instrumentation, Intelligent Instrumentation: Principles and Applications provides a comprehensive and authoritative resource on the scientific foundations from which to coordinate and advance the field. Employing a textbook-like language, this book translates methodologies to more than 80 numerical examples, and provides applications in 14 case studies for a complete and working understanding of the material.

  1. INSTRUMENTATION FOR FAR INFRARED SPECTROSCOPY.

    Energy Technology Data Exchange (ETDEWEB)

    GRIFFITHS, P.R.; HOMES, C.

    2001-05-04

    Fourier transform spectrometers developed in three distinct spectral regions in the early 1960s. Pierre Connes and his coworkers in France developed remarkably sophisticated step-scan interferometers that permitted near-infrared spectra to be measured with a resolution of better than 0.0 1 cm{sup {minus}1}. These instruments may be considered the forerunners of the step-scan interferometers made by Bruker, Bio-Rad (Cambridge, MA, USA) and Nicolet although their principal application was in the field of astronomy. Low-resolution rapid-scanning interferometers were developed by Larry Mertz and his colleagues at Block Engineering (Cambridge, MA, USA) for remote sensing. Nonetheless, the FT-IR spectrometers that are so prevalent in chemical laboratories today are direct descendants of these instruments. The interferometers that were developed for far-infrared spectrometry in Gebbie's laboratory ,have had no commercial counterparts for at least 15 years. However, it could be argued that these instruments did as much to demonstrate the power of Fourier transform spectroscopy to the chemical community as any of the instruments developed for mid- and near-infrared spectrometry. Their performance was every bit as good as today's rapid-scanning interferometers. However, the market for these instruments is so small today that it has proved more lucrative to modify rapid-scanning interferometers that were originally designed for mid-infrared spectrometry than to compete with these instruments with slow continuous scan or step-scan interferometers.

    The Sulfur Dioxide Analyzer measures sulfur dioxide based on absorbance of UV light at one wavelength by SO2 molecules which then decay to a lower energy state by emitting UV light at a longer wavelength. Specifically, SO2 + hυ1 →SO2 *→SO2 + hυ2 The emitted light is proportional to the concentration of SO2 in the optical cell. External communication with the analyzer is available through an Ethernet port configured through the instrument network of the AOS systems. The Model 43i-TLE is part of the i-series of Thermo Scientific instruments. The i-series instruments are designed to interface with external computers through the proprietary Thermo Scientific iPort Software. However, this software is somewhat cumbersome and inflexible. Brookhaven National Laboratory (BNL) has written an interface program in National Instruments LabView that both controls the Model 43i-TLE Analyzer AND queries the unit for all measurement and housekeeping data. The LabView vi (the software program written by BNL) ingests all raw data from the instrument and outputs raw data files in a uniform data format similar to other instruments in the AOS and described more fully in Section 6.0 below.

    Full Text Available A condição cultural contemporânea desafia a vivência religiosa. Vivemos um momento de nova demanda: busca-se hoje, uma relação com o dogma e uma vivência religiosa mais livres. Corre-se o risco, todavia, que esse desejo, que é de fato um dos grandes valores de nossa cultura, acabe se satisfazendo com propostas espirituais superficiais. A partir dessa preocupação, e entendendo que a mística, enquanto processo vivido pelo sujeito rumo ao encontro com o Mistério Santo, tem contribuições importantes para essa problemática, procuraremos empreender uma reflexão sobre a relação entre mística e teologia, o desencontro moderno e os sinais de reencontro que já se pode visualizar na atualidade. Refletiremos sobre a marginalização e mística, ocorrida na modernidade, as suspeitas que pairaram sobre os místicos, a divisão entre espiritualidade e teologia que adveio do triunfo do racionalismo e finalmente sobre o novo interesse pela mística que vai se esboçando na teologia contemporânea a partir da afirmação de uma nova concepção de revelação no contexto de renovação conciliar. Palavras-chaves: Mística. Espiritualidade. Teologia.   Abstract Our contemporary cultural condition challenges our religion experience. As a result, we live in a moment of a new spiritual demand: people are seeking a relationship with the dogma and at the same time a less strict religious experience. However, we are taking a risk with this new spiritual desire, which is in fact one of the strongest values in our culture; this might lead to religious satisfaction via superficial spiritual propositions. This concern, along with the mysticism involved in the process of one’s path towards the acceptance of the holy mysticism, has indeed contributed to this issue. We shall reflect upon the relationship between mysticism and theology and its modern mismatch, as well as on the signs of reunion that we can already visualize nowadays. We shall reflect

  4. On Representative Spaceflight Instrument and Associated Instrument Sensor Web Framework

    2007-01-01

    Sensor Web-based adaptation and sharing of space flight mission resources, including those of the Space-Ground and Control-User communication segment, could greatly benefit from utilization of heritage Internet Protocols and devices applied for Spaceflight (SpaceIP). This had been successfully demonstrated by a few recent spaceflight experiments. However, while terrestrial applications of Internet protocols are well developed and understood (mostly due to billions of dollars in investments by the military and industry), the spaceflight application of Internet protocols is still in its infancy. Progress in the developments of SpaceIP-enabled instrument components will largely determine the SpaceIP utilization of those investments and acceptance in years to come. Likewise SpaceIP, the development of commercial real-time and instrument colocated computational resources, data compression and storage, can be enabled on-board a spacecraft and, in turn, support a powerful application to Sensor Web-based design of a spaceflight instrument. Sensor Web-enabled reconfiguration and adaptation of structures for hardware resources and information systems will commence application of Field Programmable Arrays (FPGA) and other aerospace programmable logic devices for what this technology was intended. These are a few obvious potential benefits of Sensor Web technologies for spaceflight applications. However, they are still waiting to be explored. This is because there is a need for a new approach to spaceflight instrumentation in order to make these mature sensor web technologies applicable for spaceflight. In this paper we present an approach in developing related and enabling spaceflight instrument-level technologies based on the new concept of a representative spaceflight Instrument Sensor Web (ISW).

    Cao, Shuai; Chen, Xiang

    2014-01-01

    A portable instrument for arteriosclerosis assessment containing sensor module, acquisition board and embedded module was developed for home care in this paper. The sensor module consists of one ECG module and three pulse wave extraction modules, synchronously acquiring human ECG and pulse wave signal of carotid, radial, and dorsal, respectively. The acquisition board converts the sensor module's analog output signals into digital signals and transmits them to the embedded module. The embedded module realizes the functions including signal display, storage and the calculation and output of pulse wave velocity. The structure of the proposed portable instrument is simple, easy to use, and easy to expand. Small size, low cost, and low power consumption are also the advantages of this device. Experimental results demonstrated that the proposed portable instrument for arteriosclerosis assessment has high accuracy, good repeatability and can assess the degree of atherosclerosis appropriately.

    Clark, P. E.; Millar, P. S.; Yeh, P. S.; Feng, S.; Brigham, D.; Beaman, B.

    We are developing a small cold temperature instrument package concept that integrates a cold temperature power system with ultra low temperature ultra low power electronics components and power supplies now under development into a 'cold temperature surface operational' version of a planetary surface instrument package. We are already in the process of developing a lower power lower temperature version for an instrument of mutual interest to SMD and ESMD to support the search for volatiles (the mass spectrometer VAPoR, Volatile Analysis by Pyrolysis of Regolith) both as a stand alone instrument and as part of an environmental monitoring package. We build on our previous work to develop strategies for incorporating Ultra Low Temperature/Ultra Low Power (ULT/ULP) electronics, lower voltage power supplies, as well as innovative thermal design concepts for instrument packages. Cryotesting has indicated that our small Si RHBD CMOS chips can deliver >80% of room temperature performance at 40K (nominal minimum lunar surface temperature). We leverage collaborations, past and current, with the JPL battery development program to increase power system efficiency in extreme environments. We harness advances in MOSFET technology that provide lower voltage thresholds for power switching circuits incorporated into our low voltage power supply concept. Conventional power conversion has a lower efficiency. Our low power circuit concept based on 'synchronous rectification' could produce stable voltages as low as 0.6 V with 85% efficiency. Our distributed micro-battery-based power supply concept incorporates cold temperature power supplies operating with a 4 V or 8 V battery. This work will allow us to provide guidelines for applying the low temperature, low power system approaches generically to the widest range of surface instruments.

  7. Mobile Instruments Measure Atmospheric Pollutants

    Science.gov (United States)

    2009-01-01

    As a part of NASA's active research of the Earth s atmosphere, which has included missions such as the Atmospheric Laboratory of Applications and Science (ATLAS, launched in 1992) and the Total Ozone Mapping Spectrometer (TOMS, launched on the Earth Probe satellite in 1996), the Agency also performs ground-based air pollution research. The ability to measure trace amounts of airborne pollutants precisely and quickly is important for determining natural patterns and human effects on global warming and air pollution, but until recent advances in field-grade spectroscopic instrumentation, this rapid, accurate data collection was limited and extremely difficult. In order to understand causes of climate change and airborne pollution, NASA has supported the development of compact, low power, rapid response instruments operating in the mid-infrared "molecular fingerprint" portion of the electromagnetic spectrum. These instruments, which measure atmospheric trace gases and airborne particles, can be deployed in mobile laboratories - customized ground vehicles, typically - to map distributions of pollutants in real time. The instruments must be rugged enough to operate rapidly and accurately, despite frequent jostling that can misalign, damage, or disconnect sensitive components. By measuring quickly while moving through an environment, a mobile laboratory can correlate data and geographic points, revealing patterns in the environment s pollutants. Rapid pollutant measurements also enable direct determination of pollutant sources and sinks (mechanisms that remove greenhouse gases and pollutants), providing information critical to understanding and managing atmospheric greenhouse gas and air pollutant concentrations.

Na instituição analisada, a resolução deste problema é feita manualmente, tornando o processo árduo e demorado, além de frequentemente não produzir soluções que atendam a todas as restrições do problema. Desta forma, faz-se necessário automatizar o processo de alocação e, além disso, recorrer a estratégias computacionais que proporcionem soluções de qualidade e baixo custo. Devido à natureza combinatória do problema, recorreu-se à metaheurística Busca Tabu, que tem se mostrado adequada para a resolução desta classe de problemas. O algoritmo proposto parte de uma solução inicial gerada por um procedimento construtivo, o qual é capaz de produzir soluções viáveis em menos de um segundo. A seguir, esta solução é refinada pela Busca Tabu usando-se movimentos de realocação e troca de aulas entre salas para explorar o espaço de busca. O algoritmo proposto foi testado usando-se dados relativos à alocação de aulas de um semestre letivo e demonstrou ser bastante eficiente, tendo gerado soluções de alta qualidade quando comparado com a solução manual.

A partir da consideração dos processos de violação de seus direitos humanos, sistematicamente comprometidos devido a estigmas e processos discriminatórios, busca-se evidenciar a necessidade de uma política de saúde específica a esta população, na perspectiva da integralidade da atenção e da eqüidade no sistema de saúde. O desafio da construção de uma política de atenção integral à saúde dessa população, tal como prevista no programa de governo federal Brasil sem Homofobia, implica a complexificação e alargamento do que se compreende por direitos sexuais e reprodutivos para a efetiva promoção da eqüidade e universalidade do acesso aos bens e serviços.This paper discusses whether a specific health policy for Gays, Lesbians, Bisexuals, Transvestites and Transsexuals is a good way to improve their lives and health situation, recognizing that their human rights are systematically violated by prejudice and discrimination processes. A health policy could be a strong political and technical instrument for achieving integrality in health care and equity in the health system. Building a health policy according to the constitutional right of universality and integrality in health care is proposed by the Federal Government's program called No Homophobia in Brazil. For its consolidation, we need to broaden what we understand by sexual and reproductive rights.

    Cementa Slite Power Station is a heat recovery steam generator (HRSG) with moderate steam data; 3.0 MPa and 420 deg C. The heat is recovered from Cementa, a cement industry, without any usage of auxiliary fuel. The Power station commenced operation in 2001. The layout of the plant is unusual, there are no similar in Sweden and very few world-wide, so the operational experiences are limited. In connection with the commissioning of the power plant a R and D project was identified with the objective to minimise the manpower needed for chemistry management of the plant. The lean chemistry management is based on robust instrumentation and chemical-free water treatment plant. The concept with robust instrumentation consists of the following components; choice of on-line instrumentation with a minimum of O and M and a chemical-free water treatment. The parameters are specific conductivity, cation conductivity, oxygen and pH. In addition to that, two fairly new on-line instruments were included; corrosion monitors and differential pH calculated from specific and cation conductivity. The chemical-free water treatment plant consists of softening, reverse osmosis and electro-deionisation. The operational experience shows that the cycle chemistry is not within the guidelines due to major problems with the operation of the power plant. These problems have made it impossible to reach steady state and thereby not viable to fully verify and validate the concept with robust instrumentation. From readings on the panel of the online analysers some conclusions may be drawn, e.g. the differential pH measurements have fulfilled the expectations. The other on-line analysers have been working satisfactorily apart from contamination with turbine oil, which has been noticed at least twice. The corrosion monitors seem to be working but the lack of trend curves from the mainframe computer system makes it hard to draw any clear conclusions. The chemical-free water treatment has met all

    Our recent work has concentrated on the development of high-resolution PET instrumentation reflecting in part the growing importance of PET in nuclear medicine imaging. We have developed a number of positron imaging instruments and have the distinction that every instrument has been placed in operation and has had an extensive history of application for basic research and clinical study. The present program is a logical continuation of these earlier successes. PCR-I, a single ring positron tomograph was the first demonstration of analog coding using BGO. It employed 4 mm detectors and is currently being used for a wide range of biological studies. These are of immense importance in guiding the direction for future instruments. In particular, PCR-II, a volume sensitive positron tomograph with 3 mm spatial resolution has benefited greatly from the studies using PCR-I. PCR-II is currently in the final stages of assembly and testing and will shortly be placed in operation for imaging phantoms, animals and ultimately humans. Perhaps the most important finding resulting from our previous study is that resolution and sensitivity must be carefully balanced to achieve a practical high resolution system. PCR-II has been designed to have the detection characteristics required to achieve 3 mm resolution in human brain under practical imaging situations. The development of algorithms by the group headed by Dr. Chesler is based on a long history of prior study including his joint work with Drs. Pelc and Reiderer and Stearns. This body of expertise will be applied to the processing of data from PCR-II when it becomes operational.

    The Soil Moisture Active Passive (SMAP) mission, scheduled for launch by the end of 2014, is being developed to measure the soil moisture and soil freeze/thaw state on a global scale over a three-year period. The accuracy, resolution, and global coverage of SMAP measurements are invaluable across many science and applications disciplines including hydrology, climate, carbon cycle, and the meteorological, environment, and ecology applications communities. The SMAP observatory is composed of a despun bus and a spinning instrument platform that includes both a deployable 6 meter aperture low structural frequency Astromesh reflector and a spin control system. The instrument section has engendered challenging mechanical system issues associated with the antenna deployment, flexible antenna pointing in the context of a multitude of disturbances, spun section mass properties, spin control system development, and overall integration with the flight system on both mechanical and control system levels. Moreover, the multitude of organizations involved, including two major vendors providing the spin subsystem and reflector boom assembly plus the flight system mechanical and guidance, navigation, and control teams, has led to several unique system engineering challenges. Capturing the key physics associated with the function of the flight system has been challenging due to the many different domains that are applicable. Key interfaces and operational concepts have led to complex negotiations because of the large number of organizations that integrate with the instrument mechanical system. Additionally, the verification and validation concerns associated with the mechanical system have had required far-reaching involvement from both the flight system and other subsystems. The SMAP instrument mechanical systems engineering issues and their solutions are described in this paper.

    Dennis, B. R.; Koczan, S. P.; Stephani, E. L.

    1985-10-01

    A new method of extracting natural heat from the Earth's crust was invented at the Los Alamos National Laboratory in 1970. It uses fluid pressures (hydraulic fracturing) to produce cracks that connect two boreholes drilled into hot rock formations of low initial permeability. Pressurized water is then circulated through this connected underground loop to extract heat from the rock and bring it to the surface. The creation of the fracture reservior began with drilling boreholes deep within the Precambrian basement rock at the Fenton Hill Test Site. Hydraulic fracturing, flow testing, and well-completion operations required unique wellbore measurements using downhole instrumentation systems that would survive the very high borehole temperatures, 320(0)C (610(0)F). These instruments were not available in the oil and gas industrial complex, so the Los Alamos National Laboratory initiated an intense program upgrading existing technology where applicable, subcontracting materials and equipment development to industrial manufactures, and using the Laboratory resources to develop the necessary downhole instruments to meet programmatic schedules.

    The Plasma Wave Instrument on the Polar spacecraft is designed to provide measurements of plasma waves in the Earth's polar regions over the frequency range from 0.1 Hz to 800 kHz. Three orthogonal electric dipole antennas are used to detect electric fields, two in the spin plane and one aligned along the spacecraft spin axis. A magnetic loop antenna and a triaxial magnetic search coil antenna are used to detect magnetic fields. Signals from these antennas are processed by five receiver systems: a wideband receiver, a high-frequency waveform receiver, a low-frequency waveform receiver, two multichannel analyzers; and a pair of sweep frequency receivers. Compared to previous plasma wave instruments, the Polar plasma wave instrument has several new capabilities. These include (1) an expanded frequency range to improve coverage of both low- and high-frequency wave phenomena, (2) the ability to simultaneously capture signals from six orthogonal electric and magnetic field sensors, and (3) a digital wideband receiver with up to 8-bit resolution and sample rates as high as 249k samples s(exp -1).

    The Strontium Iodide Radiation Instrumentation (SIRI) is designed to space-qualify new gamma-ray detector technology for space-based astrophysical and defense applications. This new technology offers improved energy resolution, lower power consumption and reduced size compared to similar systems. The SIRI instrument consists of a single europiumdoped strontium iodide (SrI2:Eu) scintillation detector. The crystal has an energy resolution of 3% at 662 keV compared to the 6.5% of traditional sodium iodide and was developed for terrestrial-based weapons of mass destruction (WMD) detection. SIRI's objective is to study the internal activation of the SrI2:Eu material and measure the performance of the silicon photomultiplier (SiPM) readouts over a 1-year mission. The combined detector and readout measure the gammaray spectrum over the energy range of 0.04 - 4 MeV. The SIRI mission payoff is a space-qualified compact, highsensitivity gamma-ray spectrometer with improved energy resolution relative to previous sensors. Scientific applications in solar physics and astrophysics include solar flares, Gamma Ray Bursts, novae, supernovae, and the synthesis of the elements. Department of Defense (DoD) and security applications are also possible. Construction of the SIRI instrument has been completed, and it is currently awaiting integration onto the spacecraft. The expected launch date is May 2018 onboard STPSat-5. This work discusses the objectives, design details and the STPSat-5 mission concept of operations of the SIRI spectrometer.

    Full Text Available As pesquisas tradicionais sobre liderança fazem uso de uma abordagem atomizada, que desconsidera os efeitos de diferentes padrões (gestalts do construto e prioriza a lógica de uma variável por vez. A partir dessa crítica, o objetivo no presente trabalho é analisar a relação de distintas gestalts (configurações de liderança transformacional com o comprometimento organizacional. Para a consecução desse objetivo, foram analisados 331 questionários de funcionários de oito organizações do setor de serviços. O método de pesquisa é classificado como levantamento (survey, com amostragem não probabilística por conveniência. Para o tratamento dos dados, fez-se uso da técnica de modelagem de equações estruturais no processo de análise da validade e confiabilidade das escalas. Na sequência, a análise de cluster evidenciou três configurações de liderança, denominadas: desorientação, subliderança e conversão. Para a verificação da influência dessas gestalts sobre o comprometimento organizacional, foi testado um modelo linear generalizado - MANCOVA fatorial. Os resultados indicaram a relação entre as configurações de liderança transformacional e as dimensões afetiva, instrumental e normativa do comprometimento; entretanto, para o comprometimento instrumental, a relação é mediada pelo grau de instrução dos liderados. Por fim, são discutidas as implicações dos achados empíricos.

    2009-08-01

    A retrospective clinical review. To review the use of modern instrumentation of the spine for congenital spinal deformities. Spinal instrumentation has evolved since the advent of the Harrington rod. There is a paucity of literature, which discusses the use of modern spinal instrumentation in congenital spine deformity cases. This review focuses on modern instrumentation techniques for congenital scoliosis and kyphosis. A systematic review was performed of the literature to discuss spinal implant use for congenital deformities. Spinal instrumentation may be safely and effectively used in cases of congenital spinal deformity. Spinal surgeons taking care of children with congenital spine deformities need to be trained in all aspects of modern spinal instrumentation.

    1992-09-01

    The prevention and control of biohazards arising from the use of laboratory instruments have become increasingly important in clinical and research applications. Centrifuges can be susceptible to contamination because of intense wear on primary containers (specimen tubes and bottles), worn O-ring container seals, or rotors and buckets lacking tight seals. A recent study by the Center for Applied Microbiology and Research, Porton Down, UK, has determined the biological safety of certain rotors in various speed ranges. This paper presents and discusses these findings.

    Full Text Available Este artigo relata os resultados de uma pesquisa de Mestrado da Escola de Ciência da Informação da UFMG que teve como objetivo investigar o comportamento de busca e uso de informação sobre o ambiente organizacional externo, por parte dos gestores das empresas de micro e pequeno portes do segmento de biotecnologia de Belo Horizonte/Minas Gerais. Com esta pesquisa procurou-se responder às seguintes questões: se é fato que as organizações devem interagir com o ambiente externo para desenvolver e manter sua competitividade, qual é a importância do processo de busca e uso de informações externas? Sob que condições o uso das informações coletadas torna-se um redutor de incertezas para as organizações de micro e pequeno portes? Esta pesquisa foi desenvolvida utilizando-se da análise qualitativa, obtida com a realização de entrevistas com gestores de empresas de biotecnologia mais especificamente ligadas ao segmento de saúde humana da área de diagnóstico, na região de Belo Horizonte, Minas Gerais. Os resultados levam-nos a concluir que ambientes, cenários e pessoas diferentes têm necessidades, comportamentos, análises e usos de informações diferenciados. Não existe um padrão único de comportamento de busca e uso de informações externas, e a redução das incertezas independe da quantidade de informação coletada e ou mesmo processos estruturados. A redução da incerteza se concentra nos indivíduos e na sua capacidade pessoal de adicionar valor à “informação”, informação esta que poderá ser utilizada para responder a uma pergunta, resolver um problema, tomar uma decisão, negociar uma posição ou compreender uma situação.

    In a companion paper, we have reported a >5σ detection of degree scale B-mode polarization at 150 GHz by the Bicep2 experiment. Here we provide a detailed study of potential instrumental systematic contamination to that measurement. We focus extensively on spurious polarization that can potentially arise from beam imperfections. We present a heuristic classification of beam imperfections according to their symmetries and uniformities, and discuss how resulting contamination adds or cancels in maps that combine observations made at multiple orientations of the telescope about its boresight axis. We introduce a technique, which we call “deprojection,” for filtering the leading order beam-induced contamination from time-ordered data, and show that it reduces power in Bicep2's actual and null-test BB spectra consistent with predictions using high signal-to-noise beam shape measurements. We detail the simulation pipeline that we use to directly simulate instrumental systematics and the calibration data used as input to that pipeline. Finally, we present the constraints on BB contamination from individual sources of potential systematics. We find that systematics contribute BB power that is a factor of ∼10× below Bicep2's three-year statistical uncertainty, and negligible compared to the observed BB signal. The contribution to the best-fit tensor/scalar ratio is at a level equivalent to r = (3–6) × 10{sup −3}.

  14. Instrumentation for mass spectrometry: 1997

    Energy Technology Data Exchange (ETDEWEB)

    McLuckey, S.A.

    1997-08-01

    All mass spectrometry experiments involve the manipulation of material, an interface with the mass spectrometer, ionization, ion manipulation/analysis, detection and data collection/reduction. Each of these elements involve instrumentation. The wide range of species now amenable to mass spectrometry and the diverse areas of physical science in which it plays a role have led to a seemingly unlimited array of instrumental combinations. However, only a limited number of mass analyzers, and their combinations, dominate. The dominant analyzers include time-of-flight, Fourier transform ion cyclotron resonance, the Paul trap, the mass filter, and the sector mass spectrometer. Why there are so few (or so many, depending upon one`s point of view) can be understood upon consideration of a set of mass analyzer figures of merit. These include mass resolution, mass accuracy, mass range, dynamic range, abundance sensitivity, precision, efficiency, speed, MS{sup n} capability, compatibility with the ionizer, cost, and size. The most appropriate form of mass spectrometry is determined by the priorities of the particular measurement placed on the various mass analyzer characteristics and the relative strengths of the analyzers in meeting the requirements. Each of the analyzer types has a unique set of figures of merit that makes it optimally suited for particular applications. This paper discusses these figures of merit, provides data illustrating recent developments for each analyzer type, and gives the figures of merit of each type of analyzer as they stand in 1997. 101 refs., 24 figs.

    The Copernicus Sentinel 5 Precursor (S5P), scheduled for launch in 2016, is the first of the sentinels dedicated to monitoring of the atmospheric composition. The main application areas of the mission are air quality, climate and the ozone layer. The single payload of the S5P mission is TROPOspheric Monitoring Instrument (TROPOMI). TROPOMI is a nadir viewing shortwave spectrometer that will measure in the UV-visible wavelength range (270-500 nm), the near infrared (710-770 nm) and the shortwave infrared (2314-2382 nm). TROPOMI will have an unprecedented spatial resolution of about 7x7 km2 at nadir. The spatial resolution is combined with a wide swath to allow for daily global coverage. The high spatial resolution serves two goals: (1) emissions sources can be detected with more accuracy and (2) the number of cloud-free ground pixels will increase substantially. The TROPOMI/S5P geophysical (Level 2) data products include nitrogen dioxide, carbon monoxide, ozone (total column, tropospheric column & profile), methane, sulphur dioxide, formaldehyde and aerosol and cloud parameters. In this contribution we will present the TROPOMI instrument performance and the new science opportunities that it will enable.

    2002-01-01

    Several attempts have been made recently to apply techniques such as model checking and theorem proving to the analysis of programs. This shall be seen as a current trend to analyze real software systems instead of just their designs. This includes our own effort to develop a model checker for Java, the Java PathFinder 1, one of the very first of its kind in 1998. However, model checking cannot handle very large programs without some kind of abstraction of the program. This paper describes a complementary scalable technique to handle such large programs. Our interest is turned on the observation part of the equation: How much information can be extracted about a program from observing a single execution trace? It is our intention to develop a technology that can be applied automatically and to large full-size applications, with minimal modification to the code. We present a tool, Java PathExplorer (JPaX), for exploring execution traces of Java programs. The tool prioritizes scalability for completeness, and is directed towards detecting errors in programs, not to prove correctness. One core element in JPaX is an instrumentation package that allows to instrument Java byte code files to log various events when executed. The instrumentation is driven by a user provided script that specifies what information to log. Examples of instructions that such a script can contain are: 'report name and arguments of all called methods defined in class C, together with a timestamp'; 'report all updates to all variables'; and 'report all acquisitions and releases of locks'. In more complex instructions one can specify that certain expressions should be evaluated and even that certain code should be executed under various conditions. The instrumentation package can hence be seen as implementing Aspect Oriented Programming for Java in the sense that one can add functionality to a Java program without explicitly changing the code of the original program, but one rather writes an

    Full Text Available As protection of innovation is possible using a variety of intellectual property instruments, the current paper aims at emphasizing the vulnerabilities of these instruments in order to facilitate the right choice in terms of protection, exploitation and dissemination of innovation. Based on a review of the intellectual property instruments and their related risk factors, the study identifies and formulates specific proactive strategies which arise from the fact that an instrument alone does not allow for effective protection, exploitation and dissemination and oftentimes the owners of innovation should combine traditional and alternative instruments. Therefore, the results of this analysis represent a helpful tool for managers in the decisional process.

A total of 86.8% were identified in the census and 0.2% in the Mortality Information System. Of those identified, 1,716 were interviewed, representing a follow-up rate of 71.4%. In this study, the school census proved to be an effective method for finding students.

    The figure shows an instrument incorporating an infrared camera for detecting small hydrogen fires. The instrument has been developed as an improved replacement for prior infrared and ultraviolet instruments used to detect hydrogen fires. The need for this or any such instrument arises because hydrogen fires (e.g., those associated with leaks from tanks, valves, and ducts) pose a great danger, yet they emit so little visible light that they are mostly undetectable by the unaided human eye. The main performance advantage offered by the present instrument over prior hydrogen-fire-detecting instruments lies in its greater ability to avoid false alarms by discriminating against reflected infrared light, including that originating in (1) the Sun, (2) welding torches, and (3) deliberately ignited hydrogen flames (e.g., ullage-burn-off flames) that are nearby but outside the field of view intended to be monitored by the instrument. Like prior such instruments, this instrument is based mostly on the principle of detecting infrared emission above a threshold level. However, in addition, this instrument utilizes information on the spatial distribution of infrared light from a source that it detects. Because the combination of spatial and threshold information about a flame tends to constitute a unique signature that differs from that of reflected infrared light originating in a source not in the field of view, the incidence of false alarms is reduced substantially below that of related prior threshold- based instruments.

    Full Text Available Online personalization of hearing instruments refers to learning preferred tuning parameter values from user feedback through a control wheel (or remote control, during normal operation of the hearing aid. We perform hearing aid parameter steering by applying a linear map from acoustic features to tuning parameters. We formulate personalization of the steering parameters as the maximization of an expected utility function. A sparse Bayesian approach is then investigated for its suitability to find efficient feature representations. The feasibility of our approach is demonstrated in an application to online personalization of a noise reduction algorithm. A patient trial indicates that the acoustic features chosen for learning noise control are meaningful, that environmental steering of noise reduction makes sense, and that our personalization algorithm learns proper values for tuning parameters.

    2003-01-01

    The key science instrument on the Bering satellite mission is a relative small telescope with an entrance aperture of 300 mm and a focal length between 500 and 1000 mm. The detection of potential targets is performed by one of the target scanning advanced stellar compasses (ASCs). This procedure...... results in a simple prioritized list of right ascension, declination, proper motion and intensity of each prospective target. The telescope itself has a dedicated ASC Camera Head Unit (CHU) mounted on the secondary mirror, largely co-aligned with the telescope. This CHU accurately determines the telescope......'s pointing direction. To achieve fast tracking over a large solid angle, the telescope pointing is achieved by means of a folding mirror in the optical pathway. When a prospective target approaches the telescope FOV, the ASC on the secondary will guide the folding mirror into position such that the target...

    Asteroid surface material is expected to become photoelectrically charged, and is likely to be transported through electrostatic levitation. Understanding any movement of the surface material is relevant to proposed space missions to return samples to Earth for detailed isotopic analysis. Motivated by preparations for the Marco Polo sample return mission, we present electrostatic modelling for a real asteroid, Itokawa, for which detailed shape information is available, and verify that charging effects are likely to be significant at the terminator and at the edges of shadow regions for the Marco Polo baseline asteroid, 1999JU3. We also describe the Asteroid Charge Experiment electric field instrumentation intended for Marco Polo. Finally, we find that the differing asteroid and spacecraft potentials on landing could perturb sample collection for the short landing time of 20min that is currently planned.

    Two special calorimeters are foreseen for the instrumentation of the very forward region of the ILC detector, a luminometer designed to measure the rate of low angle Bhabha scattering events with a precision better than 10-3 and a low polar angle calorimeter, adjacent to the beam-pipe. The latter will be hit by a large amount of beamstrahlung remnants. The amount and shape of these depositions will allow a fast luminosity estimate and the determination of beam parameters. The sensors of this calorimeter must be radiation hard. Both devices will improve the hermeticity of the detector in the search for new particles. Finely segmented and very compact calorimeters will match the requirements. Due to the high occupancy fast front-end electronics is needed. The design of the calorimeters developed and optimised with Monte Carlo simulations is presented. Sensors and readout electronics ASICs have been designed and prototypes are available. Results on the performance of these major components are summarised.

    Fiber optic sensing technology has emerged in recent years offering tremendous advantages over conventional aircraft instrumentation systems. The advantages of fiber optic sensors over their conventional counterparts are well established; they are lighter, smaller, and can provide enormous numbers of measurements at a fraction of the total sensor weight. After a brief overview of conventional and fiber-optic sensing technology, this paper presents an overview of the research that has been conducted at NASA Dryden Flight Research Center in recent years to advance this promising new technology. Research and development areas include system and algorithm development, sensor characterization and attachment, and real-time experimentally-derived parameter monitoring for ground- and flight-based applications. The vision of fiber optic smart structure technology is presented and its potential benefits to aerospace vehicles throughout the lifecycle, from preliminary design to final retirement, are presented.

    Full Text Available Problems related to water management in Costa Rica have an economic origin. Partly, as a consequence of a natural condition of water richness, as well as the concept of public service with fees that don´t promote neither investment nor efficiency of water resource use. Solutions must be targeted toward the economic conditions generating pollution, little efficiency, and lesser infiltration area. Water social cost regarding its use and pollution must be recognized and paid. The water user fee and pollution fee represent a step forward. A higher application of this kind of instruments will generate profit-benefit to the economy and might encourage the protection of the environment and natural resources.

    2006-10-01

    Full Text Available The qualifying of supervision as “prudential” is used to differentiate it from other forms of supervision, which regards issues related to banking consumer protection. In order to achieve its goal, prudential supervision needs relevant information, provided mostly by the credit institutions their selves. Hence, the existence of a reporting system is essential, a system capable to insure, on the one hand, homogenity of the provided data and, on the other hand, its efficient processing. One indirect instrument which was used more and more during the last decade in banking supervision is represented by credit registers. The first system is directly associated either to the central bank or the supervision authority, and is, in most of cases, managed by the latter. The second system, the so called credit bureau, is mostly operated by private banks.

    Full Text Available INTRODUCTION : Laparoscopic splenectomy (LS is an accepted procedure for elective splenectomy. Advancement in technology has extended the possibility of LS in massive splenomegaly [Choy et al., J Laparoendosc Adv Surg Tech A 14(4, 197-200 (2004], trauma [Ren et al., Surg Endosc 15(3, 324 (2001; Mostafa et al., Surg Laparosc Endosc Percutan Tech 12(4, 283-286 (2002], and cirrhosis with portal hypertension [Hashizume et al., Hepatogastroenterology 49(45, 847-852 (2002]. In a developing country, these advanced gadgets may not be always available. We performed LS using conventional and reusable instruments in a public teaching the hospital without the use of the advanced technology. The technique of LS and the outcome in these patients is reported. MATERIALS AND METHODS : Patients undergoing LS for various hematological disorders from 1998 to 2004 were included. Electrocoagulation, clips, and intracorporeal knotting were the techniques used for tackling short-gastric vessels and splenic pedicle. Specimen was delivered through a Pfannensteil incision. RESULTS : A total of 26 patients underwent LS. Twenty-two (85% of patients had spleen size more than 500 g (average weight being 942.55 g. Mean operative time was 214 min (45-390 min. The conversion rate was 11.5% ( n = 3. Average duration of stay was 5.65 days (3-30 days. Accessory spleen was detected and successfully removed in two patients. One patient developed subphrenic abscess. There was no mortality. There was no recurrence of hematological disease. CONCLUSION : Laparoscopic splenectomy using conventional equipment and instruments is safe and effective. Advanced technology has a definite advantage but is not a deterrent to the practice of LS.

    In 1981 and 1985, two editions of a catalog of non-destructive nuclear measurement instrumentation, and material control and surveillance equipment, were published by Brookhaven National Laboratory (BNL). The last edition of the catalog included one hundred and twenty-five entries covering a wide range of devices developed in the US and abroad. More than ten years have elapsed since the publication of the more recent Catalog. Devices described in it have undergone significant modifications, and new devices have been developed. Therefore, in order to assist specialists in the field of Material Control and Accounting (MC and A), a new catalog has been created. Work on this instrumentation catalog started in 1997 as a cooperative effort of Brookhaven National Laboratory (BNL), operated by Brookhaven Science Associates under contract to the US Department of Energy, and the All-Russian Research Institute of Automatics (VNIIA), subordinate institute of the Atomic Energy Ministry of the Russian Federation, within the collaborative US-Russia Material Protection, Control, and Accounting (MPC and A) Program. Most of the equipment included in the Catalog are non-destructive assay (NDA) measurement devices employed for purposes of accounting, confirmation, and verification of nuclear materials. Other devices also included in the Catalog are employed in the detection and deterrence of unauthorized access to or removal of nuclear materials (material control: containment and surveillance). Equipment found in the Catalog comprises either: (1) complete devices or systems that can be used for MC and A applications; or (2) parts or components of complete systems, such as multi-channel analyzers, detectors, neutron generators, and software. All devices are categorized by their status of development--from prototype to serial production.

    Turbulence Heating ObserveR (THOR) is the first mission ever flown in space dedicated to plasma turbulence. The Electric Field Instrument (EFI) is to measure the electric field vector in the frequency range 0-200 kHz. EFI consists of two sets of sensors: Spin-plane Double Probes (EFI-SDP) providing high sensitivity DC electric field in the spacecraft spin plane (2D), and the High-Frequency Antenna (EFI-HFA) providing 3D electric field at frequencies above 1 kHz. EFI-SDP consists of 4 biased spherical probes extended on 50 m long wire booms, 90 degrees apart in the spin plane, giving a 100 m baseline for each of the two spin-plane electric field components. EFI-HFA consists of 6 x 1.25 m long monopoles, forming 3 dipolar antennas crossed at 90 degrees to each other. In addition to the sensors, EFI contains HFA and SDP pre-amplifiers, as well as bias electronics boards (BEBs) hosted in the man electronics box of the Field and Wave processor (FWP). As THOR spacecraft has a sun-pointing spin axis, EFI-SDP measures the electric field in the plane approximately orthogonal to the sun using long wire booms. The sun-pointing attitude greatly reduces errors due to wake effects and asymmetric photoelectron clouds, enabling the highly accurate in comparison to earlier missions ±0.1 mV/m near-DC electric field measurements. Interferometry using the electric field probes can be used to infer wavelengths and scale sizes at the smallest scales in the plasma. EFI also measures the floating potential of the satellite, which can be used to estimate the plasma density at very high time resolution (up to a few hundred Hz). The sun-pointing attitude greatly reduces changes in the illuminated area, and hence the associated spin-dependent errors. In combination with densities derived from the observed plasma frequency emission line, EFI monitors the plasma density from DC to a few hundred Hz. EFI measurements characterize electric field and density variations associated with kinetic

    2003-01-01

    Method and apparatus are provided for a non-invasive bubble measuring instrument operable for detecting, distinguishing, and counting gaseous embolisms such as bubbles over a selectable range of bubble sizes of interest. A selected measurement volume in which bubbles may be detected is insonified by two distinct frequencies from a pump transducer and an image transducer, respectively. The image transducer frequency is much higher than the pump transducer frequency. The relatively low-frequency pump signal is used to excite bubbles to resonate at a frequency related to their diameter. The image transducer is operated in a pulse-echo mode at a controllable repetition rate that transmits bursts of high-frequency ultrasonic signal to the measurement volume in which bubbles may be detected and then receives the echo. From the echo or received signal, a beat signal related to the repetition rate may be extracted and used to indicate the presence or absence of a resonant bubble. In a preferred embodiment, software control maintains the beat signal at a preselected frequency while varying the pump transducer frequency to excite bubbles of different diameters to resonate depending on the range of bubble diameters selected for investigation.

    Abundant and affordable energy is required for U.S. economic stability and national security. Advanced nuclear power plants offer the best near-term potential to generate abundant, affordable, and sustainable electricity and hydrogen without appreciable generation of greenhouse gases. To that end, Idaho National Laboratory (INL) has been charged with leading the revitalization of nuclear power in the U.S. The INL vision is to become the preeminent nuclear energy laboratory with synergistic, world-class, multi-program capabilities and partnerships by 2015. The vision focuses on four essential destinations: (1) Be the preeminent internationally-recognized nuclear energy research, development, and demonstration laboratory; (2) Be a major center for national security technology development and demonstration; (3) Be a multi-program national laboratory with world-class capabilities; (4) Foster academic, industry, government, and international collaborations to produce the needed investment, programs, and expertise. Crucial to that effort is the inclusion of research in advanced instrumentation, control, and intelligent systems (ICIS) for use in current and advanced power and energy security systems to enable increased performance, reliability, security, and safety. For nuclear energy plants, ICIS will extend the lifetime of power plant systems, increase performance and power output, and ensure reliable operation within the system's safety margin; for national security applications, ICIS will enable increased protection of our nation's critical infrastructure. In general, ICIS will cost-effectively increase performance for all energy security systems.

    The successful research man is the one who asks himself the right question. Research must go on primarily in the mind and only secondarily in the physical and biological world. It is only too easy to confuse the choice of a proper tool and the choice of a proper question. Some tools are quite unsuited to certain questions and some questions cannot be answered without the appropriate tool.There has been in recent years a large amount of discussion about whether the high costs and the extensive time period required for experimental watershed* research is really worth the investment. Recent discussions of this matter have cited as major criticisms of the instrumented basin that they are expensive, they leak water, they are unrepresentative, they produce changes too small for detection, and it is difficult to transfer the results. (See Hewlett, Lull, and Reinhart, 1969.) These are all questions worth talking about, but in one sense they tend to obscure the main issue. The main issue is what do we want to learn? If we can decide what it is we want to know, then we can logically ask ourselves what is the best way of going about obtaining that knowledge. It is in this context that we are most likely to place the experimental watershed in a useful and logical position in a classification of research methods.

    LISA Pathfinder (LPF) is an ESA-launched demonstration mission of key technologies required for the joint NASA-ESA gravitational wave observatory in space, LISA. As part of the LPF interferometry investigations, analytic models of noise sources and corresponding noise subtraction techniques have been developed to correct for effects like the coupling of test mass jitter into displacement readout, and fluctuations of the laser frequency or optical pathlength difference. Ground testing of pre-flight hardware of the Optical Metrology subsystem is currently ongoing at the Albert Einstein Institute Hannover. In collaboration with NASA Goddard Space Flight Center, the LPF mission data analysis tool LTPDA is being used to analyze the data product of these tests. Furthermore, the noise subtraction techniques and in-flight experiment runs for noise characterization are being defined as part of the mission experiment master plan. We will present the data analysis outcome of preflight hardware ground tests and possible noise subtraction strategies for in-flight instrument operations.

    The Juno mission's primary science objectives include the investigation of Jupiter interior structure via the determination of its gravitational field. Juno will provide more accurate determination of Jupiter's gravity harmonics that will provide new constraints on interior structure models. Juno will also measure the gravitational response from tides raised on Jupiter by Galilean satellites. This is accomplished by utilizing Gravity Science instrumentation to support measurements of the Doppler shift of the Juno radio signal by NASA's Deep Space Network at two radio frequencies. The Doppler data measure the changes in the spacecraft velocity in the direction to Earth caused by the Jupiter gravity field. Doppler measurements at X-band (˜ 8 GHz) are supported by the spacecraft telecommunications subsystem for command and telemetry and are used for spacecraft navigation as well as Gravity Science. The spacecraft also includes a Ka-band (˜ 32 GHz) translator and amplifier specifically for the Gravity Science investigation contributed by the Italian Space Agency. The use of two radio frequencies allows for improved accuracy by removal of noise due to charged particles along the radio signal path.

    The sample collection technology and instrument concept for the Sample of Comet Coma Earth Return Mission (SOCCER) are described. The scientific goals of this Flyby Sample Return are to return to coma dust and volatile samples from a known comet source, which will permit accurate elemental and isotopic measurements for thousands of individual solid particles and volatiles, detailed analysis of the dust structure, morphology, and mineralogy of the intact samples, and identification of the biogenic elements or compounds in the solid and volatile samples. Having these intact samples, morphologic, petrographic, and phase structural features can be determined. Information on dust particle size, shape, and density can be ascertained by analyzing penetration holes and tracks in the capture medium. Time and spatial data of dust capture will provide understanding of the flux dynamics of the coma and the jets. Additional information will include the identification of cosmic ray tracks in the cometary grains, which can provide a particle's process history and perhaps even the age of the comet. The measurements will be made with the same equipment used for studying micrometeorites for decades past; hence, the results can be directly compared without extrapolation or modification. The data will provide a powerful and direct technique for comparing the cometary samples with all known types of meteorites and interplanetary dust. This sample collection system will provide the first sample return from a specifically identified primitive body and will allow, for the first time, a direct method of matching meteoritic materials captured on Earth with known parent bodies.

  2. European Languages: Instruments and Symbols

    Further, the role of Latin as the single most important European language over the centuries and as a unifying feature of European culture is discussed. Parallels are drawn between Latin as the historical European lingua franca on the one hand and English as the modern language of international communication on the other: the importance of both languages started growing after substantial territorial expansion of their speakers and it was especially the political and economic power associated to these languages that played a significant role in their diffusion and long-term influence. Taking into consideration the instrumental as well as the symbolic function of languages, the question about the relationship between English and other European languages in today’s Europe is dealt with; it is suggested that the European languages are in principle not endangered as a result of the spread of English, with the exception of those instances in which English has been taking over the functions they have traditionally performed as national or community languages. It is emphasized that the future of Europe lies in the promotion of biand multilingualism, which have, in actual fact, been present on this continent throughout its history, and which in the cases of some European languages (e.g. Catalan, Basque, Irish, etc. have been successfully enhanced over the past decades.

  3. Attention is necessary for subliminal instrumental conditioning.

    The capacity of humans and other animals to provide appropriate responses to stimuli anticipating motivationally significant events is exemplified by instrumental conditioning. Interestingly, in humans instrumental conditioning can occur also for subliminal outcome-predicting stimuli. However, it remains unclear whether attention is necessary for subliminal instrumental conditioning to take place. In two experiments, human participants had to learn to collect rewards (monetary gains) while avoiding punishments (monetary losses), on the basis of subliminal outcome-predicting cues. We found that instrumental conditioning can proceed subconsciously only if spatial attention is aligned with the subliminal cue. Conversely, if spatial attention is briefly diverted from the subliminal cue, then instrumental conditioning is blocked. In humans, attention but not awareness is therefore mandatory for instrumental conditioning, thus revealing a dissociation between awareness and attention in the control of motivated behavior.

  14. Instruments for subsurface monitoring of geothermal subsidence

    Energy Technology Data Exchange (ETDEWEB)

    O' Rourke, J.E.; Ranson, B.B.

    1979-07-01

    The requirements for a subsurface geothermal subsidence instrument were reviewed. Available instruments for monitoring subsurface displacements, both vertical and horizontal, were studied and the most capable instruments identified. Techniques and materials for improving existing or developing new instruments were evaluated. Elements of sensor and signal technology with potential for high temperature monitoring of subsidence were identified. Drawing from these studies, methods to adapt production wells for monitoring were proposed and several new instrumentation systems were conceptually designed. Finally, four instrumentation systems were selected for future development. These systems are: triple sensor induction sensor probe (with casing collar markers); triple sensor gamma ray detector probe (with radioactive markers); triple sensor reed switch probe (with magnet markers); and triple sensor oscillator-type magnet detector probe (with magnet markers). All are designed for use in well casing incorporating slip couplings or bellows sections, although the gamma ray detector probe may also be used in unlined holes. These systems all measure vertical moement. Instruments to measure horizontal displacement due to geothermal subsidence were studied and the required instrument performance was judged to be beyond the state-of-the-art. Thus, no conceptual designs for instruments to monitor horizontal movement are included.

  15. [What's new in instrumental dermatology?].

    Science.gov (United States)

    Amici, J-M

    2014-12-01

    This "What's new in instrumental dermatology" focuses on cutaneous oncologic surgery, base on a review of the 2012-2014 literature. First, the ability of dermatologists to make a good "oncologic reading of tumors" is the key of radical surgical treatment. Advantages and disadvantages of the biopsy are discussed. Then, the second message is the management of anticoagulants, that should not be interrupted for skin surgery. Despite recommendations, this practice is not followed in 40% of cases; this point is critical because bleeding complications are minor compared to potential morbidity of thrombotic events when stopping these medications. Regarding infection, nasal carriage of Staphylococcus aureus is identified as a risk factor for wound infection. A preoperative shower with chlorhexidine and mupirocin topical decolonization of nostril reduces this risk. Surgical techniques are trying to reach minimalism, by reducing undermining and scarring. On the trunk, using deep slow resorbable sutures improve scarring. In addition using adhesive sutures (strip) reduce the wideness of scar. On the face, the lower third of the nose is the most challenging because of the free edges, which are deformable. In this location bilobed or trilobed transposition flap offer the advantage of remaining in the nasal aesthetic unit and not disturbing the free edges of the nasal orifices. Regarding scarring, early hypertrophic scar is now well defined and linked with transposition flaps of the nasal region. An early treatment with intralesional corticosteroid injection appears to be effective. Finally, the biological mechanism of the effectiveness of compression in the prevention and treatment of dystrophic scar is now clear. The mechanotransduction explain how a mechanical stress of the skin activates biological cell pathways, which regulate the quality of collagen synthesis and the arrangement of skin fibrosis.

    Full Text Available OBJECTIVE: Doubts, competitiveness and preparation for the residency examination increase stress and insecurity at the end of medical course. Well-being is very important at this point, but it is known that medical students are reluctant to seek help, particularly for emotional problems. This study investigated the relationship among well-being, perceived needs and help-seeking in final-year students. METHODS: Well-being was assessed using Beck's Inventories of Anxiety (BAI and Depression (BDI and the WHOQOL-brief (quality of life. A questionnaire was used to assess perceived needs and medical school support resources. RESULTS: The students reported good quality of life (68% but presented anxiety (27%, depression (20% and impaired social functioning. Fifty-one percent of the students acknowledged academic needs and 25% psychological needs. Only a portion of the students with anxiety and depression or bad quality of life used the institutional support. Female gender, perceived psychological needs and anxiety symptoms were associated to the use of the Mental Health Service. Satisfaction with mentoring relationships and positive changes were associated to Mentoring attendance. CONCLUSION: There are different factors involved in help-seeking and identifying specificities in the use of institutional support resources can help to develop strategies to sensitize students about help-seeking during the medical courseOBJETIVO: Dúvidas, competição e o exame de residência aumentam o estresse e a insegurança ao final do curso; entretanto, sabe-se que alunos de Medicina são resistentes a procurar ajuda, especialmente para problemas emocionais.

    1999-05-01

    Numerous evaluation tools have been developed to document various aspects of wound status or appearance of pressure ulcers. These include the Pressure Sore Status Tool (PSST), Pressure Ulcer Scale for Healing (PUSH Tool), Sussman Wound Healing Tool (SWHT), Sessing scale, and the Wound Healing Scale (WHS). A critical appraisal of the literature was undertaken to examine the purpose and methods for the development of each instrument, the extent to which the instruments have been validated to date, the practicality of their use, and the work that remains to be done to establish their suitability for clinical and/or research purposes. All of these instruments have been developed to describe and evaluate change in pressure ulcer status over time with the exception of the WHS, which was developed as an alternative to reverse staging. More of the validation parameters have been addressed for the PSST and the Sessing scale than for the PUSH Tool, the SWHT, and the WHS. All of the instruments can be completed within approximately 5 minutes except the PSST, which requires 10 to 15 minutes to complete. For all instruments, experience with wounds and training in the use of the instrument are required to improve reliability. For each of the measurement instruments, suggestions are made that would complete necessary validation procedures and thus prepare the instruments for clinical and/or research purposes.

    2002-02-01

    The Measurements Of Pollution In The Troposphere (MOPITT) instrument is one of five instruments flying on NASA's Terra (formerly EOS-AM1) spacecraft that was launched in December 1999. This paper describes the MOPITT instrument mechanical configuration and how it was derived based on system considerations and spacecraft interfaces. These system level considerations include contamination control, EMC/EMI, thermal, optical and structural behavior. The key spacecraft interfaces include mechanical mounting, optical field-of-view (FOV), and thermal transfer. In addition, a detailed discussion is provided for the cryogenic region of the instrument that contains detectors, cold optics, warm optics, and active coolers. Special test fixtures were designed and incorporated in this region of the instrument to permit cooling of the detectors during ambient atmospheric conditions. Some of these test fixtures were designed to fly due to the difficulty in removing them. This utility of operating the instrument's cryogenic detectors within the laboratory environment was extremely beneficial during the instrument optical alignment, EMC testing, and special optical system tests. Final configuring (or closeout) of the instrument's cryogenic region for flight was performed to balance contamination and EMC risks. On-orbit data about the effectiveness of this closeout is provided.

  2. The nonlinear physics of musical instruments

    Science.gov (United States)

    Fletcher, N. H.

    1999-05-01

    Musical instruments are often thought of as linear harmonic systems, and a first-order description of their operation can indeed be given on this basis, once we recognise a few inharmonic exceptions such as drums and bells. A closer examination, however, shows that the reality is very different from this. Sustained-tone instruments, such as violins, flutes and trumpets, have resonators that are only approximately harmonic, and their operation and harmonic sound spectrum both rely upon the extreme nonlinearity of their driving mechanisms. Such instruments might be described as `essentially nonlinear'. In impulsively excited instruments, such as pianos, guitars, gongs and cymbals, however, the nonlinearity is `incidental', although it may produce striking aural results, including transitions to chaotic behaviour. This paper reviews the basic physics of a wide variety of musical instruments and investigates the role of nonlinearity in their operation.

  3. Instrumental Divergence and the Value of Control.

    Science.gov (United States)

    Mistry, Prachi; Liljeholm, Mimi

    2016-11-04

    A critical aspect of flexible choice is that alternative actions yield distinct consequences: Only when available action alternatives produce distinct outcome states does discrimination and selection between actions allow an agent to flexibly obtain the currently most desired outcome. Here, we use instrumental divergence - the degree to which alternative actions differ with respect to their outcome probability distributions - as an index of flexible instrumental control, and assess the influence of this novel decision variable on choice preference. In Experiment 1, when other decision variables, such as expected value and outcome entropy, were held constant, we found a significant preference for high instrumental divergence. In Experiment 2, we used an "auto- vs. self-play" manipulation to eliminate outcome diversity as a source of behavioral preferences, and to contrast flexible instrumental control with the complete absence of voluntary choice.

    Full Text Available This review article presents an overview of instruments available on the market for measurement of particulate matter. The main instruments and methods of measuring concentration (gravimetric, optical, and microbalance and size distribution Scanning Mobility Particle Sizer (SMPS, Electrical Low Pressure Impactor (ELPI, and others were described and compared. The aim of this work was to help researchers choose the most suitable equipment to measure particulate matter. When choosing a measuring instrument, a researcher must clearly define the purpose of the study and determine whether it meets the main specifications of the equipment. ELPI and SMPS are the suitable devices for measuring fine particles; the ELPI works in real time. In health-related studies, a Diffusion Charger is the instrument that best characterizes the surface of ultrafine particles. Several methods and different particle measuring instruments should be used to confirm the values obtained during sampling.

    The Sample Analysis at Mars Instrument Simulator (SAMSIM) is a numerical model dedicated to plan and validate operations of the Sample Analysis at Mars (SAM) instrument on the surface of Mars. The SAM instrument suite, currently operating on the Mars Science Laboratory (MSL), is an analytical laboratory designed to investigate the chemical and isotopic composition of the atmosphere and volatiles extracted from solid samples. SAMSIM was developed using Matlab and Simulink libraries of MathWorks Inc. to provide MSL mission planners with accurate predictions of the instrument electrical, thermal, mechanical, and fluid responses to scripted commands. This tool is a first example of a multi-purpose, full-scale numerical modeling of a flight instrument with the purpose of supplementing or even eliminating entirely the need for a hardware engineer model during instrument development and operation. SAMSIM simulates the complex interactions that occur between the instrument Command and Data Handling unit (C&DH) and all subsystems during the execution of experiment sequences. A typical SAM experiment takes many hours to complete and involves hundreds of components. During the simulation, the electrical, mechanical, thermal, and gas dynamics states of each hardware component are accurately modeled and propagated within the simulation environment at faster than real time. This allows the simulation, in just a few minutes, of experiment sequences that takes many hours to execute on the real instrument. The SAMSIM model is divided into five distinct but interacting modules: software, mechanical, thermal, gas flow, and electrical modules. The software module simulates the instrument C&DH by executing a customized version of the instrument flight software in a Matlab environment. The inputs and outputs to this synthetic C&DH are mapped to virtual sensors and command lines that mimic in their structure and connectivity the layout of the instrument harnesses. This module executes

  9. Aquarius Instrument and Salinity Retrieval

    2011-01-01

    Aquarius has been designed to map the surface salinity field of the global ocean from space a parameter important for understanding ocean circulation and its relationship to climate and the global water cycle. Salinity is measured remotely from space by measuring the thermal emission from the ocean surface. This is done at the low frequency end of the microwave spectrum (e.g. 1.4 GHz) where the emission is sufficiently sensitive to changes in salinity to be detected with sophisticated radiometers. The goal is to monitor the seasonal and interannual variation of the large scale features of the surface salinity field in the open ocean by providing maps on a monthly basis with a spatial resolution of 150 km and an accuracy of 0.2 psu. These are challenging requirements that have led to some unique features of the instrument. These include: a) The addition of a co-located scatterometer to help provide a correction for roughness; b) The addition of a polarimetric channel (third Stokes parameter) to the radiometer to help correct for Faraday rotation; c) Asun-synchronous orbit with a 6 pm ascending equatorial crossing to minimize Faraday rotation and with the antennas looking away from the sun toward the nighttime side to minimize contamination by radiation from the sun; and d) An antenna designed to limit side lobes in the direction of rays from the sun. In addition, achieving the accuracy goal of 0.2 psu requires averaging over one month and to do this requires a highly stable radiometer. Aquarius has three separate radiometers that image in pushbroom fashion with the three antenna beams looking across track. The antenna is a 2.5-m diameter, offset parabolic reflector with three feed horns and the three beams are arranged to image with the boresight aligned to look across track, roughly perpendicular to the spacecraft heading and pointing away from the Sun. The three beams point at angles of theta = 25.8 deg., 33.8 deg. and 40.3 deg. with respect to the spacecraft

    2013-01-01

    High intraoral pressure generated when playing some wind instruments has been linked to a variety of health issues. Prior research has focused on Western classical instruments, but no work has been published on ethnic wind instruments. This study measured intraoral pressure when playing six classes of ethnic wind instruments (N = 149): Native American flutes (n = 71) and smaller samples of ethnic duct flutes, reed instruments, reedpipes, overtone whistles, and overtone flutes. Results are presented in the context of a survey of prior studies, providing a composite view of the intraoral pressure requirements of a broad range of wind instruments. Mean intraoral pressure was 8.37 mBar across all ethnic wind instruments and 5.21 +/- 2.16 mBar for Native American flutes. The range of pressure in Native American flutes closely matches pressure reported in other studies for normal speech, and the maximum intraoral pressure, 20.55 mBar, is below the highest subglottal pressure reported in other studies during singing...

  11. How To Control Color Appearance With Instrumentation

    Science.gov (United States)

    Burns, Margaret E.

    1980-05-01

    Colorimetry, as defined by the International Commission on Illumination, is the measurement of colors, made possible by the properties of the eye and based on a set of conventions. Instrumentation for measuring object color, therefore, must be based on a human observer. The intent is to design an instrument that in effect responds as a person would, so that research development, production control and quality control areas have some means of assessing the acceptability of the appearance of a product. Investigations of a human observer's psychological response to color, and the manner in which visual observations are made, give the instrument designer and manufacturer data necessary to answer two questions: a. How can we put numbers (instrument read-out) on a perception that occurs in the brain of the observer? b. What can we learn from examination of a visual observing situation that will guide us in our design of an instrumental simulation of this situation? Involving as it does our own daily, almost unconscious, practice of making judgments concerning the things we see, the design and manufacture of color measurement instruments is an exceedingly interesting field. The advances being made concurrently today in research concerning human color vision and in optical and electronic technology will make possible increasingly useful instrumentation for quality control of product color.

    Inter-calibration of satellite instruments is critical for detection and quantification of changes in the Earth’s environment, weather forecasting, understanding climate processes, and monitoring climate and land cover change. These applications use data from many satellites; for the data to be inter-operable, the instruments must be cross-calibrated. To meet the stringent needs of such applications requires that instruments provide reliable, accurate, and consistent measurements over time. Robust techniques are required to ensure that observations from different instruments can be normalized to a common scale that the community agrees on. The long-term reliability of this process needs to be sustained in accordance with established reference standards and best practices. Furthermore, establishing physical meaning to the information through robust Système International d'unités (SI) traceable Calibration and Validation (Cal/Val) is essential to fully understand the parameters under observation. The processes of calibration, correction, stability monitoring, and quality assurance need to be underpinned and evidenced by comparison with “peer instruments” and, ideally, highly calibrated in-orbit reference instruments. Inter-calibration between instruments is a central pillar of the Cal/Val strategies of many national and international satellite remote sensing organizations. Inter-calibration techniques as outlined in this paper not only provide a practical means of identifying and correcting relative biases in radiometric calibration between instruments but also enable potential data gaps between measurement records in a critical time series to be bridged. Use of a robust set of internationally agreed upon and coordinated inter-calibration techniques will lead to significant improvement in the consistency between satellite instruments and facilitate accurate monitoring of the Earth’s climate at uncertainty levels needed to detect and attribute the mechanisms

    In preparation for the Astro 2020 Decadal Survey NASA has commissioned the study four flagship missions spanning to a wide range of observable wavelengths: the Origins Space Telescope (OST, formerly the Far-Infrared Surveyor), Lynx (formerly the X-ray Surveyor), the Large UV/Optical/Infrared Surveyor (LUVOIR) and the Habitable Exoplanet Imager (HabEx). One of the key scientific objectives of the latter two is the detection and characterization of the earth-like planets around nearby stars using the direct imaging technique (along with a broad range of investigations regarding the architecture of and atmospheric composition exoplanetary systems using this technique). As a consequence dedicated exoplanet instruments are being studied for these mission concepts. This paper discusses the design of the coronagraph instrument for the architecture "A" (15 meters aperture) of LUVOIR. The material presented in this paper is aimed at providing an overview of the LUVOIR coronagraph instrument. It is the result of four months of discussions with various community stakeholders (scientists and technologists) regarding the instrument's basic parameters followed by meticulous design work by the the GSFC Instrument Design Laboratory team. In the first section we review the main science drivers, presents the overall parameters of the instrument (general architecture and backend instrument) and delve into the details of the currently envisioned coronagraph masks along with a description of the wavefront control architecture. Throughout the manuscript we describe the trades we made during the design process. Because the vocation of this study is to provide a baseline design for the most ambitious earth-like finding instrument that could be possibly launched into the 2030's, we have designed an complex system privileged that meets the ambitious science goals out team was chartered by the LUVOIR STDT exoplanet Working Group.

    Instrumental variables analysis is a methodology to mitigate the effects of measured and unmeasured confounding in observational studies of treatment effects. Geographic area is increasingly used as an instrument. We conducted a literature review to determine the properties of geographic area in studies of cancer treatments. We identified cancer studies performed in the United States which incorporated instrumental variable analysis with area-wide treatment rate within a geographic region as the instrument. We assessed the degree of treatment variability between geographic regions, assessed balance of measured confounders afforded by geographic area and compared the results of instrumental variable analysis to those of multivariable methods. Geographic region as an instrument was relatively common, with 22 eligible studies identified, many of which were published in high-impact journals. Treatment rates did not vary greatly by geographic region. Covariates were not balanced by the instrument in the majority of studies. Eight out of eleven studies found statistically significant effects of treatment on multivariable analysis but not for instrumental variables, with the central estimates of the instrumental variables analysis generally being closer to the null. We recommend caution and an investigation of IV assumptions when considering the use of geographic region as an instrument in observational studies of cancer treatments. The value of geographic region as an instrument should be critically evaluated in other areas of medicine. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Low-light level night vision device and thermal infrared imaging binocular photoelectric instrument are used widely. The maladjustment of binocular instrument ocular axises parallelism will cause the observer the symptom such as dizziness, nausea, when use for a long time. Binocular photoelectric equipment digital calibration instrument is developed for detecting ocular axises parallelism. And the quantitative value of optical axis deviation can be quantitatively measured. As a testing instrument, the precision must be much higher than the standard of test instrument. Analyzes the factors that influence the accuracy of detection. Factors exist in each testing process link which affect the precision of the detecting instrument. They can be divided into two categories, one category is factors which directly affect the position of reticle image, the other category is factors which affect the calculation the center of reticle image. And the Synthesize error is calculated out. And further distribute the errors reasonably to ensure the accuracy of calibration instruments.

    This slide presentation reviews the results of a study on the use of wireless instrumentation and sensors on future launch vehicles. The use of wireless technologies would if feasible would allow for fewer wires, and allow for more flexibility. However, it was generally concluded that wireless solutions are not currently ready to replace wired technologies for launch vehicles. The recommendations of the study were to continue to use wired sensors as the primary choice for vehicle instrumentation, and to continue to assess needs and use wireless instrumentation where appropriate. The future work includes support efforts for wireless technologies, and continue to monitor the development of wireless solutions.

    Although speech and vocal music are consistently shown to impair serial recall for visually presented items, instrumental music does not always produce a significant disruption. This study investigated the features of instrumental music that would modulate the disruption in serial recall. 24 students were presented sequences of nine digits and required to recall the digits in order of presentation. Instrumental music as played either forward or backward during the task. Forward music caused significantly more disruption than did silence, whereas the reversed music did not. Some higher-order factor may be at work in the effect of background music on serial recall.

    The development of an instrument to measure the concentration of particles in gas is described in this report. An in situ instrument was designed and constructed which sizes individual particles and counts the number of occurrences for several size classes. Although this instrument was designed to detect the size distribution of slag and seed particles generated at an experimental coal-fired magnetohydrodynamic power facility, it can be used as a nonintrusive diagnostic tool for other hostile industrial processes involving the formation and growth of particulates. Two of the techniques developed are extensions of the widely used crossed beam velocimeter, providing simultaneous measurement of the size distribution and velocity of articles.

    The application of Superheated Droplet Detectors in dark matter searches by the SIMPLE project uses an acoustic instrumentation sensitive to the shock wave generated by the bubble nucleation of the refrigerant droplets. Previous instrumentation has been unable to distinguish between true nucleation and background noise events in the device, in particular microleaks associated with the escape of overpressuring nitrogen gas into the surrounding water bath. We here describe the development of an improved instrumentation which is shown to provide this discrimination capacity through a reduced noise level of the transducer amplification circuitry.

    The spectrum acquired at the sample phototnultiplier tube of a fluorescence spectrophotometer is a product of the sample spectrum and the instrument function. The determination of the instrument function and its removal from the acquired spectrum is often critical to the accurate determination of the physical properties of the sample. Methods are discussed for the determination and removal of the instrument function from excitation and emission spectra. Methods considered include quantum counters and ratio circuits for excitation correction, and emission correction against calibrated excitation systems, calibrated tungsten lamps, and NBS standard quinine sulfate.

    2016-01-01

    Understanding the causal impact of beliefs on contributions in Threshold Public Goods (TPGs) is particularly important since the social optimum can be supported as a Nash Equilibrium and best-response contributions are a function of beliefs. Unfortunately, investigations of the impact of beliefs on behavior are plagued with endogeneity concerns. We create a set of instruments by cleanly and exogenously manipulating beliefs without deception. Tests indicate that the instruments are valid and relevant. Perhaps surprisingly, we fail to find evidence that beliefs are endogenous in either the one-shot or repeated-decision settings. TPG allocations are determined by a base contribution and beliefs in a one shot-setting. In the repeated-decision environment, once we instrument for first-round allocations, we find that second-round allocations are driven equally by beliefs and history. Moreover, we find that failing to instrument prior decisions overstates their importance.

Nine neutron-scattering instruments will come into operation within the first year, seven of them are situated at neutron guides. The electronics and software required for the various instruments are standardized as far as possible. The SINQ instrument control software (SICS) is implemented as a client server system. The SICS server is implemented in ANSI-C on a digital Unix platform and uses only Posix compliant system calls for maximum portability. Clients provide the user interface, which may be either of the traditional command line type or a more modern graphical user interface. Communication with the front-end electronics is via the TCP/IP internet protocol. Measured data are stored in the NeXus format, a common data exchange format for neutron scattering and X-ray instruments.

    Over the last ten years, a team at Lawrence Livermore National Laboratory created fieldable instruments that performed identification/quantification via bioassays. These instruments have been based on molecular surface-recognition assays, such as immunoassays, and on nucleic-acid-based assays, such as the polymerase chain reaction. In 1996, we participated in the Joint Field Trials 3, employing both immunoassays as well as the polymerase chair reaction. In 1998, we participated in the Joint Field Trials 4, using only the real-time polymerase chain reaction, as implemented on a 10-chamber instrument. Our hand-held, real-time PCR instrument, known as HANAA has been commercialized as the Bioseeq{reg_sign}, by Smiths Detection. More recently, teams from LLNL have built and fielded an autonomous pathogen detection system (APDS).

    Since the introduction of robotic surgery for radical prostatectomy, the cost-benefit of this technology has been under scrutiny. While robotic surgery professes to offer multiple advantages, including reduced blood loss, reduced length of stay, and expedient recovery, the associated costs tend to be significantly higher, secondary to the fixed cost of the robot as well as the variable costs associated with instrumentation. This study provides a simple framework for the careful consideration of costs during the selection of equipment and materials. Two experienced robotic surgeons at our institution as well as several at other institutions were queried about their preferred instrument usage for robot-assisted prostatectomy. Costs of instruments and materials were obtained and clustered by type and price. A minimal set of instruments was identified and compared against alternative instrumentation. A retrospective review of 125 patients who underwent robotically assisted laparoscopic prostatectomy for prostate cancer at our institution was performed to compare estimated blood loss (EBL), operative times, and intraoperative complications for both surgeons. Our surgeons now conceptualize instrument costs as proportional changes to the cost of the baseline minimal combination. Robotic costs at our institution were reduced by eliminating an energy source like the Ligasure or vessel sealer, exploiting instrument versatility, and utilizing inexpensive tools such as Hem-o-lok clips. Such modifications reduced surgeon 1's cost of instrumentation to ∼40% less compared with surgeon 2 and up to 32% less than instrumentation used by surgeons at other institutions. Surgeon 1's combination may not be optimal for all robotic surgeons; however, it establishes a minimally viable toolbox for our institution through a rudimentary cost analysis. A similar analysis may aid others in better conceptualizing long-term costs not as nominal, often unwieldy prices, but as percent changes in

    2015-03-01

    A robust identification of the instrument currently used by the surgeon is crucial for the automatic modeling and analysis of surgical procedures. Various approaches for intra-operative surgical instrument identification have been presented, mostly based on radio-frequency identification (RFID) or endoscopic video analysis. A novel approach is to identify the instruments on the instrument table of the scrub nurse with a combination of video and weight information. In a previous article, we successfully followed this approach and applied it to multiple instances of an ear, nose and throat (ENT) procedure and the surgical tray used therein. In this article, we present a metric for the suitability of the instruments of a surgical tray for identification by video and weight analysis and apply it to twelve trays of four different surgical domains (abdominal surgery, neurosurgery, orthopedics and urology). The used trays were digitized at the central sterile services department of the hospital. The results illustrate that surgical trays differ in their suitability for the approach. In general, additional weight information can significantly contribute to the successful identification of surgical instruments. Additionally, for ten different surgical instruments, ten exemplars of each instrument were tested for their weight differences. The samples indicate high weight variability in instruments with identical brand and model number. The results present a new metric for approaches aiming towards intra-operative surgical instrument detection and imply consequences for algorithms exploiting video and weight information for identification purposes.

  14. Temporal integration and instrumental conditioned reinforcement.

    2014-09-01

    Stimuli associated with primary reinforcement for instrumental behavior are widely believed to acquire the capacity to function as conditioned reinforcers via Pavlovian conditioning. Some Pavlovian conditioning studies suggest that animals learn the important temporal relations between stimuli and integrate such temporal information over separate experiences to form a temporal map. The present experiment examined whether Pavlovian conditioning can establish a positive instrumental conditioned reinforcer through such temporal integration. Two groups of rats received either delay or trace appetitive conditioning in which a neutral stimulus predicted response-independent food deliveries (CS1→US). Both groups then experienced one session of backward second-order conditioning of the training CS1 and a novel CS2 (CS1-CS2 pairing). Finally, the ability of CS2 to function as a conditioned reinforcer for a new instrumental response (leverpressing) was assessed. Consistent with the previous demonstrations of temporal integration in fear conditioning, a CS2 previously trained in a trace-conditioning protocol served as a better instrumental conditioned reinforcer after backward second-order conditioning than did a CS2 previously trained in a delay protocol. These results suggest that an instrumental conditioned reinforcer can be established via temporal integration and raise challenges for existing quantitative accounts of instrumental conditioned reinforcement.

  15. Influence of musical instruments on tooth positions.

    Science.gov (United States)

    Herman, E

    1981-08-01

    A 2-year longitudinal investigation was conducted at five New York City junior high schools on 11- to 13-year-old children starting instrumental music education to determine what tooth movement, if any, resulted from the playing of certain musical instruments. Questionnaires, interviews, oral examinations, and dental casts were used at the start of instrumental study, after one year, and then after a second year. Statistically significant anterior tooth movements occurred in an overwhelming majority of the instrumentalists, while negligible movements were recorded for the controls over this period. As a result of this study, certain recommendations can be made by dentists when they are asked to suggest instruments which are dentally suited for children. In most cases they can suggest more than one instrument which would be of benefit dentally to the individual child, especially in the increase or reduction of overjet and overbite. The playing of the correct musical instrument can serve as an adjunct to the dentist or orthodontist in trying to accomplish certain tooth movements.

  16. Instrumental variable methods for causal inference.

    Baiocchi, Michael; Cheng, Jing; Small, Dylan S

    2014-06-15

    A goal of many health studies is to determine the causal effect of a treatment or intervention on health outcomes. Often, it is not ethically or practically possible to conduct a perfectly randomized experiment, and instead, an observational study must be used. A major challenge to the validity of observational studies is the possibility of unmeasured confounding (i.e., unmeasured ways in which the treatment and control groups differ before treatment administration, which also affect the outcome). Instrumental variables analysis is a method for controlling for unmeasured confounding. This type of analysis requires the measurement of a valid instrumental variable, which is a variable that (i) is independent of the unmeasured confounding; (ii) affects the treatment; and (iii) affects the outcome only indirectly through its effect on the treatment. This tutorial discusses the types of causal effects that can be estimated by instrumental variables analysis; the assumptions needed for instrumental variables analysis to provide valid estimates of causal effects and sensitivity analysis for those assumptions; methods of estimation of causal effects using instrumental variables; and sources of instrumental variables in health studies.

    2017-01-01

    Dermatologic surgery requires precision and accuracy given the delicate nature of procedures performed. The use of the most appropriate instrument for each action helps optimize both functionality and cosmetic outcome. To review the history of surgical instruments used in dermatology, with a focus on mechanism and evolution to the instruments that are used in current practice. A comprehensive literature search was conducted via textbook and journal research for historic references while review of current references was conducted online using multiple search engines and PubMed. There are a number of articles that review instruments in dermatology, but this article adds a unique perspective in classifying their evolution, while also presenting them as levers that serve to increase human dexterity during the course of surgery. Surgical instruments allow fine manipulation of tissue, which in turn produces optimal outcomes. Surgical tools have been around since the dawn of man, and their evolution parallels the extent to which human civilization has specialized over time. This article describes the evolution of instruments from the general surgical armamentaria to the specialized tools that are used today.

    2015-01-01

    In this paper we present a GEO instrument concept dedicated to monitoring the Earth's global spectral reflectance with a high revisit rate. Based on our measurement goals, the ideal instrument needs to be highly sensitive (SNR greater than 100) and to achieve global coverage with spectral sampling (less than or equal to 10nm) and spatial sampling (less than or equal to 1km) over a large bandwidth (380-2510 nm) with a revisit time (greater than or equal to greater than or equal to 3x/day) sufficient to fully measure the spectral-radiometric-spatial evolution of clouds and confounding factor during daytime. After a brief study of existing instruments and their capabilities, we choose to use a GEO constellation of up to 6 satellites as a platform for this instrument concept in order to achieve the revisit time requirement with a single launch. We derive the main parameters of the instrument and show the above requirements can be fulfilled while retaining an instrument architecture as compact as possible by controlling the telescope aperture size and using a passively cooled detector.

    2016-03-01

    The Sulfur Dioxide Analyzer measures sulfur dioxide based on absorbance of UV light at one wavelength by SO2 molecules which then decay to a lower energy state by emitting UV light at a longer wavelength. Specifically, SO2 + hυ1 →SO2 *→SO2 + hυ2 The emitted light is proportional to the concentration of SO2 in the optical cell. External communication with the analyzer is available through an Ethernet port configured through the instrument network of the AOS systems. The Model 43i-TLE is part of the i-series of Thermo Scientific instruments. The i-series instruments are designed to interface with external computers through the proprietary Thermo Scientific iPort Software. However, this software is somewhat cumbersome and inflexible. BNL has written an interface program in National Instruments LabView that both controls the Model 43i-TLE Analyzer AND queries the unit for all measurement and housekeeping data. The LabView vi (the software program written by BNL) ingests all raw data from the instrument and outputs raw data files in a uniform data format similar to other instruments in the AOS and described more fully in Section 6.0 below.

    The Compact Lightweight Surgery Robot from the University of Hawaii includes two teleoperated instruments and one endoscope manipulator which act in accord to perform assisted interventional medicine. The relative positions and orientations of the robotic instruments and endoscope must be known to the teleoperation system so that the directions of the instrument motions can be controlled to correspond closely to the directions of the motions of the master manipulators, as seen by the the endoscope and displayed to the surgeon. If the manipulator bases are mounted in known locations and all manipulator joint variables are known, then the necessary coordinate transformations between the master and slave manipulators can be easily computed. The versatility and ease of use of the system can be increased, however, by allowing the endoscope or instrument manipulator bases to be moved to arbitrary positions and orientations without reinitializing each manipulator or remeasuring their relative positions. The aim of this work is to find the pose of the instrument end effectors using the video image from the endoscope camera. The P3P pose estimation algorithm is used with a Levenberg-Marquardt optimization to ensure convergence. The correct transformations between the master and slave coordinate frames can then be calculated and updated when the bases of the endoscope or instrument manipulators are moved to new, unknown, positions at any time before or during surgical procedures.

  1. Increased Science Instrumentation Funding Strengthens Mars Program

    Science.gov (United States)

    Graham, Lee D.; Graff, T. G.

    2012-01-01

    As the strategic knowledge gaps mature for the exploration of Mars, Mars sample return (MSR), and Phobos/Deimos missions, one approach that becomes more probable involves smaller science instrumentation and integrated science suites. Recent technological advances provide the foundation for a significant evolution of instrumentation; however, the funding support is currently too small to fully utilize these advances. We propose that an increase in funding for instrumentation development occur in the near-term so that these foundational technologies can be applied. These instruments would directly address the significant knowledge gaps for humans to Mars orbit, humans to the Martian surface, and humans to Phobos/ Deimos. They would also address the topics covered by the Decadal Survey and the Mars scientific goals, objectives, investigations and priorities as stated by the MEPAG. We argue that an increase of science instrumentation funding would be of great benefit to the Mars program as well as the potential for human exploration of the Mars system. If the total non-Earth-related planetary science instrumentation budget were increased 100% it would not add an appreciable amount to the overall NASA budget and would provide the real potential for future breakthroughs. If such an approach were implemented in the near-term, NASA would benefit greatly in terms of science knowledge of the Mars, Phobos/Deimos system, exploration risk mitigation, technology development, and public interest.

  11. The observatories and instruments of Tycho Brahe

    Science.gov (United States)

    Wolfschmidt, Gudrun

    Tycho Brahe (1546-1601) was the most important observational astronomer until the invention of the telescope in 1608. By construction new instruments and devising new observing methods, Tycho succeeded in significantly increasing measurement accuracy: He increased the size of his instruments (e.g. a large wooden quadrant of diameter 5.4 m and a mural quadrant); he used metal and masonry rather than wood; he modified construction techniques to achieve greater stability; to provide shelter from the wind, his instruments were in subterranean nooks; his instruments were permanently and solidly mounted; for better angular readings, he developed new subdivisions and diopters (Tycho used transversals to obtain the greatest possible angular resolution readings. His instrumental sights (diopters) were specially designed to minimize errors); he carefully analysed all the errors (Tycho's aim was to reduce thethe uncertainty to less than one minute of arc); he used fundamental stars for the first time; he preferred measuring equatorial coordinates directly instead of using the zodiacal system, i.e. using the equatorial armillary sphere instead of the zodiacal armillary sphere; he tried a new measuring method with clocks and his mural quadrant (1582) for determining the right ascension; he took atmospheric refraction into account. Most of his high-accuracy instruments have been distroyed. Only two sextants, made by Jost Bürgi and Erasmus Habermel around 1600, still exist in the Narodny Technicky Muzeum (NTM) [National Technical Museum] in Prague. A model of the wooden quadrant is in the old observatory in Copenhagen, in the round tower. But we have good descriptions of the instruments (half circles of 2.3 m radius, quadrants up to 2 m radius including the mural quadrant, sextants up to 1.6 m, armillary spheres of 1.5 m radius and the great equatorial armillary sphere of 2.7 m, triquetrum and celestial globe of 1.5 m) in Tycho's book Astronomiae instauratae mechanica

    Full Text Available A Economia Solidária é hoje um movimento dividido em duas correntes teóricas, que dão ensejo a dois projetos políticos distintos: um conservador, de inserção de trabalhadores na economia capitalista, e outro radical, de transformação da economia e estabelecimento de novos valores sociais. Com relação ao projeto radical, vários desafios se interpõem no percurso, desafios estes que se ligam principalmente à dificuldade de modificar os valores que sustentam as novas práticas. Nesse sentido, este trabalho busca demonstrar a contribuição da noção de Imaginário Social na mudança de valores e efetivação de um projeto radical de Economia Solidária. Acredita-se que o entrelaçamento entre estrutura e cultura, entre práticas e valores, deve ser indissociável, e ter, como pano de fundo e força motriz, o imaginário social. --- Solidary Economy and the Issue of the Imaginary: in search of new perspectives --- Abstract: --- The Solidary Economy is now a movement in two theoretical currents, giving rise to two different political projects: a conservative, the inclusion of workers in the capitalist economy, and other radical, transformation of the economy and establishment of new social values. With the radical project, several challenges are practices in the way, these challenges that are linked mainly to the difficulty of changing the values that sustain the new practices. Accordingly, this paper aims to demonstrate the contribution of the concept of Social Imaginary in changing values and execution of a project of radical Solidary Economy. It is believed that the links between structure and culture, between practices and values should be inseparable, and have, as a background and driving force, the social imaginary.

    2008-09-01

    Full Text Available Apesar de predominar junto à população a idéia de que a violência sexual é praticada por pessoas desconhecidas, na realidade a maioria desses crimes é praticada por pessoa identificável pela vítima. Além de conseqüências físicas e psicológicas, também há risco em adquirir o vírus HIV. Para prevenção deste, em situação de risco, há orientação para uso da quimioprofilaxia anti-retroviral. Esse uso, por 28 dias, pode trazer efeitos adversos com intensidades variáveis. O conhecimento da sorologia anti-HIV do agressor torna-se fundamental para manter, ou suspender, com segurança, essa indicação. Este estudo descritivo, realizado no Conjunto Hospitalar de Sorocaba, teve como objetivo identificar os agressores e suas respectivas sorologias. Foi realizado a partir de fichas de notificação e os prontuários no período de julho de 2003 a dezembro de 2005. Encontraram-se 920 vítimas de violência sexual, com idades entre oito meses e 77 anos, havendo predomínio do sexo feminino (86,5%. Dentre os agressores, 76% foram referidos como identificáveis. Indicou-se profilaxia anti-retroviral para 24,9% das vítimas. Para 80 (33,2% agressores localizados, a busca foi realizada através de contato telefônico. Encontrou-se 52,5% em seus domicílios, 45% em Presídio/Delegacia e 2,5% no Pronto Socorro. Um agressor (1,3% apresentou sorologia positiva para HIV. As buscas encerraram-se, em sua maioria, em até seis dias (80%, possibilitando a suspensão da quimioprofilaxia em 30,6% dos casos. Concluiu-se que a busca ao denunciado permitiu conhecer sua sorologia anti-HIV e suspender, para um terço das vítimas, o uso da quimioprofilaxia anti-retroviral, diminuindo, com isso, a possibilidade de efeitos adversos.Although people believe that sexual violence is practiced by unknown people, most crimes are actually practiced by someone close to the victim. Besides physical and psychological consequences, there is the risk of acquiring the

    2009-03-01

    This white paper offers cautionary observations about the planning and development of new, large radio astronomy instruments. Complexity is a strong cost driver so every effort should be made to assign differing science requirements to different instruments and probably different sites. The appeal of shared resources is generally not realized in practice and can often be counterproductive. Instrument optimization is much more difficult with longer lists of requirements, and the development process is longer and less efficient. More complex instruments are necessarily further behind the technology state of the art because of longer development times. Including technology R&D in the construction phase of projects is a growing trend that leads to higher risks, cost overruns, schedule delays, and project de-scoping. There are no technology breakthroughs just over the horizon that will suddenly bring down the cost of collecting area. Advances come largely through careful attention to detail in the adoption of new technology provided by industry and the commercial market. Radio astronomy instrumentation has a very bright future, but a vigorous long-term R&D program not tied directly to specific projects needs to be restored, fostered, and preserved.

    Full Text Available The rapid increase and availability of mathematics software, either for classroom or individual learning activities, presents a challenge for teachers. It has been argued that many products are limited in quality. Some of the more commonly used software products have been criticized for poor content, activities which fail to address some learning issues, poor graphics presentation, inadequate documentation, and other technical problems. The challenge for schools is to ensure that the educational software used in classrooms is appropriate and effective in supporting intended outcomes and goals. This paper aimed to develop instrument for evaluating mathematics educational software in order to help teachers in selecting the appropriate software. The instrument considers the notion of educational including content, teaching and learning skill, interaction, and feedback and error correction; and technical aspects of educational software including design, clarity, assessment and documentation, cost and hardware and software interdependence. The instrument use a checklist approach, the easier and effective methods in assessing the quality of educational software, thus the user needs to put tick in each criteria. The criteria in this instrument are adapted and extended from standard evaluation instrument in several references.   Keywords: mathematics educational software, educational aspect, technical aspect.

    DeMario, Edmund E.; Lawson, Charles N.

    1993-01-01

    A nuclear fuel assembly for a pressurized water nuclear reactor has a spring and dimple structure formed in a non-radioactive insert tube placed in the top of a sensor receiving instrumentation tube thimble disposed in the fuel assembly and attached at a top nozzle, a bottom nozzle, and intermediate grids. The instrumentation tube thimble is open at the top, where the sensor or its connection extends through the cooling water for coupling to a sensor signal processor. The spring and dimple insert tube is mounted within the instrumentation tube thimble and extends downwardly adjacent the top. The springs and dimples restrain the sensor and its connections against lateral displacement causing impact with the instrumentation tube thimble due to the strong axial flow of cooling water. The instrumentation tube has a stainless steel outer sleeve and a zirconium alloy inner sleeve below the insert tube adjacent the top. The insert tube is relatively non-radioactivated inconel alloy. The opposed springs and dimples are formed on diametrically opposite inner walls of the insert tube, the springs being formed as spaced axial cuts in the insert tube, with a web of the insert tube between the cuts bowed radially inwardly for forming the spring, and the dimples being formed as radially inward protrusions opposed to the springs.

    2017-09-29

    Lumbar spinal stenosis (LSS) is primarily found in an older population. This is a similar demographic group that develops both osteoporosis and vertebral compression fractures (VCF). This report reviewed a series of patients treated for VCF that had previous lumbar surgery for symptomatic spinal stenosis. Patients that only underwent laminectomy or fusion without instrumentation had a similar distribution of VCF as the non-surgical population in the mid-thoracic, or lower thoracic and upper lumbar spine. However, in the patients that had previous short-segment spinal instrumentation, fractures were found to be located more commonly in the mid-lumbar spine or sacrum adjacent to or within one or two spinal segments of the spinal instrumentation. Adjacent-level fractures that occur due to vertebral osteoporosis after long spinal segment instrumentation has been discussed in the literature. The purpose of this report is to highlight the previously unreported finding of frequent lumbar and sacral osteoporotic fractures in post-lumbar instrumentation surgery patients. Important additional factors found were lack of preventative medical treatment for osteoporosis, and secondary effects related to inactivity, especially during the first year after surgery.

    2017-11-03

    Stigmatization is the assignment of negative perceptions to an individual because of a perceived difference from the population at large. Skin conditions are frequently the reason of social rejection with a consequent negative influence on the personal and social life of patients. The aim of the current study was to review the available instruments that can be successfully utilized to measure the stigmatization level among dermatological patients. We performed our search on PubMed up to November 2016 and utilized combinations of key phrases containing such words as stigmatization, skin, dermatology, names of various skin conditions (psoriasis, vitiligo, acne, etc.), measurement. The search found a considerable number of articles - 548. After filtering them through a precise selection process, 58 articles remained. We concentrated only on the methodological aspects to assess stigmatization in various dermatoses. The review ascertained that there exist numerous instruments in the form of questionnaires. They were utilized in various researches in order to assess the stigmatization level in patients with skin problems. We divided them into two main groups: dermatology specific instruments (6 questionnaires) and dermatosis/disease specific ones (8 questionnaires). It is recommended to use dermatology-specific instruments to compare the stigmatization level in various skin conditions. They can be utilized as well as a first line tools to study the feeling of stigmatization in specific skin diseases; however, where it is possible, they should be supplemented with the disease-specific instrument for deeper analysis of both qualities of life and stigmatization.

    The second edition of Electronic Imaging in Astronomy: Detectors and Instrumentation describes the remarkable developments that have taken place in astronomical detectors and instrumentation in recent years – from the invention of the charge-coupled device (CCD) in 1970 to the current era of very large telescopes, such as the Keck 10-meter telescopes in Hawaii with their laser guide-star adaptive optics which rival the image quality of the Hubble Space Telescope. Authored by one of the world’s foremost experts on the design and development of electronic imaging systems for astronomy, this book has been written on several levels to appeal to a broad readership. Mathematical expositions are designed to encourage a wider audience, especially among the growing community of amateur astronomers with small telescopes with CCD cameras. The book can be used at the college level for an introductory course on modern astronomical detectors and instruments, and as a supplement for a practical or laboratory class.

    The purpose of this paper is to provide an accurate overview of the development and structure of the program established by the Health Physics Society (HPS) for accrediting instrument calibration laboratories relative to their ability to accurately calibrate portable health physics instrumentation. The purpose of the program is to provide radiation protection professionals more meaningful direct and indirect access to the National Institute of Standards and Technology (NIST) national standards, thus introducing a means for improving the uniformity, accuracy, and quality of ionizing radiation field measurements. The process is designed to recognize and document the continuing capability of each accredited laboratory to accurately perform instrument calibration. There is no intent to monitor the laboratory to the extent that each calibration can be guaranteed by the program; this responsibility rests solely with the accredited laboratory.

    In the study of long-run economic growth, it is common to use historical or geographical variables as instruments for contemporary endogenous regressors. We study the interpretation of these conventional instrumental variable (IV) regressions in a general, yet simple, framework. Our aim...... is to estimate the long-run causal effect of changes in the endogenous explanatory variable. We find that conventional IV regressions generally cannot recover this parameter of interest. To estimate this parameter, therefore, we develop an augmented IV estimator that combines the conventional regression...... with a separate regression estimating the degree of persistence in the endogenous regressor. Importantly, our estimator can overcome a particular violation of the exclusion restriction that can arise when there is a time gap between the instrument and the endogenous explanatory variable. We apply our results...

    2017-01-01

    At the end of James Webb Space Telescope (JWST) OTIS (Optical Telescope Element-OTE-Integrated Science Instrument Module-ISIM) cryogenic vacuum testing in NASA Johnson Space Centers (JSCs) thermal vacuum (TV) Chamber A, contamination control (CC) engineers are mooting the idea that chamber particulate material stirred up by the repressurization process may be kept from falling into the ISIM interior to some degree by activating instrument purge flows over some initial period before opening the chamber valves. This memo describes development of a series of models designed to describe this process. These are strung together in tandem to estimate overpressure evolution from which net outflow velocity behavior may be obtained. Creeping flow assumptions are then used to determine the maximum particle size that may be kept suspended above the ISIM aperture, keeping smaller particles from settling within the instrument module.

    The Department of Energy (DOE) designated the Advanced Test Reactor (ATR) as a National Scientific User Facility (NSUF) in April 2007 to support U.S. leadership in nuclear science and technology. By attracting new research users - universities, laboratories, and industry - the ATR will support basic and applied nuclear research and development, further advancing the nation's energy security needs. A key component of the ATR NSUF effort is to prove new in-pile instrumentation techniques that are capable of providing real-time measurements of key parameters during irradiation. To address this need, an assessment of instrumentation available and under-development at other test reactors has been completed. Based on this review, recommendations are made with respect to what instrumentation is needed at the ATR and a strategy has been developed for obtaining these sensors. Progress toward implementing this strategy is reported in this document. It is anticipated that this report will be updated on an annual basis.

    The LHC under commissioning at CERN will be the world's largest superconducting accelerator and therefore makes extensive use of cryogenic instruments. These instruments are installed in the tunnel and therefore have to withstand the LHC environment that imposes radiation-tolerant design and construction. Most of the instruments require individual calibration; some of them exhibit several variants as concerns measuring span; all relevant data are therefore stored in an Oracle® database. Those data are used for the various quality assurance procedures defined for installation and commissioning, as well as for generating tables used by the control system to configure automatically the input/output channels. This paper describes the commissioning of the sensors and the corresponding electronics, the first measurement results during the cool-down of one machine sector; it discusses the different encountered problems and their corresponding solutions.

    A gas monitor detector was implemented and characterized at the Soft X-ray Research (SXR) instrument to measure the average, absolute and pulse-resolved photon flux of the LCLS beam in the energy range between 280 and 2000 eV. The detector is placed after the monochromator and addresses the need to provide reliable absolute pulse energy as well as pulse-resolved measurements for the various experiments at this instrument. This detector provides a reliable non-invasive measurement for determining flux levels on the samples in the downstream experimental chamber and for optimizing signal levels of secondary detectors and for the essential need of data normalization. The design, integration into the instrument and operation are described, and examples of its performance are given.

    2009-12-01

    The high precision radio pulsar timing required for gravitational wave detection experiments (like NANOGrav) and gravitational theory or neutron star equation-of-state tests demands that pulse phase be measured to precisions of 0.01% of the pulse period, or tens to hundreds of nano-seconds for millisecond pulsars (MSPs). This requirement means high precision instrumentation. At NRAO we are developing a state-of-the-art pulsar backend called GUPPI for these scientific problems. GUPPI provides wide bandwidth (up to 800 MHz), high dynamic range (8-bit sampling), substantially improved interference resistance (compared to all other GBT pulsar instruments), and full polarization capabilities. Currently it is being commissioned as a fully supported facility instrument for the GBT in a digital filterbank (i.e. incoherent dedispersion) mode. Within the next six months full coherent dedispersion capabilities are planned.

    Full Text Available The complexity of the Regin malware underlines the importance of reverse engineering in modern incident response. The present study shows that such complexity can be overcome: substantial information about adversary tactics, techniques and procedures is obtained from reverse engineering. An introduction to the Regin development framework is provided along with instrumentation guidelines. Such instrumentation enables experimentation with malware modules. So analysis can derectly leverage malware’s own code without the need to program an analysis toolkit. As an application of the presented instrumentation, the underlying botnet architecture is analysed. Finally conclusions from different perspectives are provided: defense, attack and counter intelligence.

  1. [Interventions during labor for reducing instrumental deliveries].

    Schmitz, T; Meunier, E

    2008-12-01

    Several interventions have been demonstrated, with high evidence levels (EL), to be associated with reduced instrumental deliveries and should therefore be undertaken during labor for increasing spontaneous vaginal deliveries. Using a partogram (EL1) and continuous support during labor and childbirth (EL1) lead to fewer operative vaginal deliveries. Systematic early amniotomy increases the frequency of fetal heart rate abnormalities (EL2) without decreasing the incidence of instrumental deliveries (EL1) and should thus be avoided. Early oxytocin in dysfunctional labor (EL2) and manual rotation of posterior and transverse presentations (EL3) may reduce operative vaginal deliveries. Even without epidural analgesia, any upright or lateral positions compared to supine or lithotomy positions do not reduce instrumental deliveries (EL2). Epidural analgesia alters significantly instrumental delivery rates and therefore patient management in the labor ward. Indeed, when used with high concentration of local anesthetic, epidural analgesia is associated with increased operative vaginal deliveries (EL1), at least in part because of increased posterior presentations (EL2). However, the effect of epidural analgesia on instrumental delivery rates closely depends from the type of anesthetic and concentrations used. This effect is reduced when low concentrations of local anesthetic are used in combination with fat-soluble morphinated agent (EL1). Finally, for nulliparous women with continuous epidural analgesia, unless irresistible urge to push or medical indication to shorten second stage of labor, delayed pushing is associated with reduced difficult instrumental deliveries (EL1). Fundal pressure maneuvers should be prohibited because of their inefficiency (EL2) and dangerousness (EL4).

    The Primordial Ination Explorer (PIXIE) uses a nulling Fourier Transform Spectrometer to measure the absoluteintensity and linear polarization of the cosmic microwave background and diuse astrophysical foregrounds.PIXIE will search for the signature of primordial ination and will characterize distortions from a blackbodyspectrum, both to precision of a few parts per billion. Rigorous control of potential instrumental eects isrequired to take advantage of the raw sensitivity. PIXIE employs a highly symmetric design using multipledierential nulling to reduce the instrumental signature to negligible levels. We discuss the systematic errorbudget and mitigation strategies for the PIXIE mission.

    Full Text Available The paper approaches the low-level details of the code generated by compilers whose format permits outside actions. Binary code modifications are manually done when the internal format is known and understood, or automatically by certain tools developed to process the binary code. The binary code instrumentation goals may be various from security increasing and bug fixing to development of malicious software. The paper highlights the binary code instrumentation techniques by code injection to increase the security and reliability of a software application. Also, the paper offers examples for binary code formats understanding and how the binary code injection may be applied.

    The primary measurement output from the Thermo Scientific Ozone Analyzer is the concentration of the analyte (O3) reported at 1-s resolution in units of ppbv in ambient air. Note that because of internal pneumatic switching limitations the instrument only makes an independent measurement every 4 seconds. Thus, the same concentration number is repeated roughly 4 times at the uniform, monotonic 1-s time base used in the AOS systems. Accompanying instrument outputs include sample temperatures, flows, chamber pressure, lamp intensities and a multiplicity of housekeeping information. There is also a field for operator comments made at any time while data is being collected.

  14. Elizabethan Instrument Makers - The Origins of the London Trade in Precision Instrument Making

    Europe in the sixteenth century experienced a period of unprecedented vitality and innovation in the spheres of science and commerce. The Americas had been discovered and the colonizing nations had an urgent need for mathematical instruments for navigation and surveying. In 1540 the Elizabethan age saw the establishment of the precision instrument-making trade in London, a trade that would become world-famous in the succeeding two centuries. The mathematical instruments needed by astronomers, navigators, and surveyors owe much of their development to the work of the Flemish mathematician and astronomer, Gemma Frisius, and to the map and globe maker, Gerard Mercator, both of whom studied at Louvain. However it was Thomas Gemini who is credited with starting the London trade in 1540: his reputation came from making the plates for his own printing of the Anatomy of Vesalius, and the astrolabs he made and presented to Edward VI and Elizabeth I, which survive today. He was followed by Humphrey Cole, and other makers whose instruments have survived, including Ryther, Knyvyn, and Whitwell. This book first describes the context in which the Elizabethan trade began, and the influence of the instruments taken to Florence by Sir Robert Dudley in 1606. The second part catalogues in detail every surviving instrument from this period, signed and unsigned, that has been traced. The catalogue is accompanied by fine photographs which illustrate both the instruments and the techniques used to identify unsigned instruments.

    In spite of the established benefits of anterolateral decompression and instrumentation (ALDI) for thoracolumbar burst fractures (TLBF), the indications for supplementary posterior instrumentation remain unclear. A retrospective review of clinical and radiographic data of a prospective cohort of 73 patients who underwent ALDI for TLBF from T12 to L4. The mean age of the cohort was 42 ± 15 years, with 49 males and 24 females. Forty-six patients had neurological deficit, and 27 were intact. Owing to symptomatic settling, supplemental posterior instrumentation was performed in 7 out of 73 patients. The age of patients requiring supplemental posterior instrumentation (59 ± 14 years) exceeded that of patients who did not (41 ± 16, p=0.004). Otherwise, the patients who required posterior instrumentation were comparable to those treated with ALDI in terms of body mass index (BMI), American Spinal Injury Association (ASIA) scores on admission and follow-up, residual spinal canal, and local kyphosis on admission and follow-up. The posterior ligamentous complex (PLC) integrity was assessed in 38 patients in whom the MRI scans were retrievable, 31 successfully treated with ALDI, and all 7 undergoing supplementary posterior instrumentation. Subgroup analysis demonstrated that there was no difference in the incidence of PLC disruption between the 2 groups (p=0.257). Secondary supplemental posterior instrumentation was deemed necessary in 10% of cases following ALDI. Age was the only significant risk factor predicating supplemental posterior instrumentation.

  19. Instrumental traditions and theories of light the uses of instruments in the optical revolution

    CERN Document Server

    Chen, Xiang

    2000-01-01

    An analysis of the optical revolution in the context of early 19th century Britain. Far from merely involving the replacement of one optical theory by another, the revolution also involved substantial changes in instruments and the practices that surrounded them. People's judgements about classification, explanation and evaluation were affected by the way they used such optical instruments as spectroscopes, telescopes, polarisers, photometers, gratings, prisms and apertures. There were two instrumental traditions in this historical period, each of which nurtured a body of practice that exemplified how optical instruments should be operated, and especially how the eye should be used. These traditions functioned just like paradigms, shaping perspectives and even world views. Readership: Scholars and graduate students in the history of science, history of instrument, philosophy of science and science studies. Can also be used as a textbook in graduate courses on 19th century physics.

    Full Text Available Acolher demandas e assistir mulheres que sofrem violência é parte dos direitos em saúde, embora a assistência não esteja estruturada e ocorra pouca detecção de casos. Buscou-se um diagnóstico de situação em serviços, avaliando-se a emergência de demandas referidas à violência por parte das usuárias de uma unidade básica da rede pública, contrastando-se a demanda espontânea com a busca ativa de casos. Realizou-se um primeiro estudo por técnicas de observação participante, seguida de estudo de prontuário, com 142 mulheres sendo acompanhadas; num segundo estudo, em uma amostra de 322 usuárias, aplicou-se entrevista. Em atividades grupais observou-se relatos espontâneos e nos prontuários médicos registros de demandas espontâneas; o mesmo não ocorreu em consultas individuais. A entrevista detectou uma prevalência de casos muito maior. Então, a possibilidade de detecção de casos, seu acolhimento e algumas respostas do serviço, requer especificidade de abordagem e cuidados próprios para que a violência contra mulheres possa emergir como parte da demanda usual na saúde.In spite of poorly structured assistance and the fact that only a few instances of abuse are detected, the response to women's demands and assisting those who have been victims of violence is part of their right to healthcare. This work attempts to diagnose the situation regarding health services through the assessment of the degree of emergency in violence-related demands coming from users of a healthcare facility of the public network through the comparison of results from spontaneous demands with results obtained when actively searching for cases. A first study was conducted with the utilization of participatory observation techniques, followed by the study of patient files, with the follow-up of 142 women; a second study, with a sample of 322 users, was based on an assessment screening. Spontaneous expression occurred during group activities and was
