    2014-12-01

    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.

  2. A dor enquanto paixão

    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.

  4. A enfermagem enquanto disciplina, profissão e trabalho

    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.

    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.

  12. Melancolia e náusea: do destino enquanto fundamento do caráter trágico ao absurdo existencial

    Directory of Open Access Journals (Sweden)

    Thiago Rodrigues

    2014-08-01

    Full Text Available A partir da perspectiva intelectualista grega, na qual o dualismo entre corpo e alma requer o primado do discurso racional [lógos] em detrimento do páthos filosófico, busca-se com este artigo associar a noção de "desmedida" [hybris] com a noção de melancolia. Essa associação ganha ainda mais relevo, quando a aproximamos da interpretação de Simone Weil para o poema épico de Homero, a Ilíada. Se essa aproximação se justifica, então é patente a aproximação entre o caráter trágico que o destino adquire, na perspectiva clássica, e a noção de contingência enquanto fundamento do absurdo existencial, no pensamento existencialista.

    Full Text Available This article aims to review the literature on the term interdisciplinarity, from the perspective of great researchers of the subject and show the main hurdles in the quest for interdisciplinarity school. The terminterdisciplinarity comes from the expression discipline, then the understanding of interdisciplinarity is necessary to explain the discipline. The positivist principle is guiding the division of knowledge in specific areas in order topromote a greater depth in a more restricted area of knowledge, so the term discipline in the epistemological fieldor in the educational field, represents an imposition of limits of performance, methodologies own, languages,among others. These limits fragment knowledge and reality which makes a more global and totalitarian reality. In literature the term interdisciplinarity has no single definition, but it seems a consensus among many authors asMorin, Fazenda, Pombo, Lenoir among others, that interdisciplinarity is presented as an alternative in thefragmentation of knowledge and interdisciplinary projects do not pass between the extinction disciplines, but the search for reconnection between the knowledge contained in each knowledge area, revitalizing the intersectionsand interrelationships between them, either through an interdisciplinary approach as advocated by Fazenda or theway of thinking as advocated Morin.O presente artigo se propõe a fazer uma revisão da literatura, acerca do termo interdisciplinaridade, à luz de grandes estudiosos do tema e mostrar os principais obstáculos na busca pela interdisciplinaridade escolar. O termo interdisciplinaridade apresenta como núcleo central a expressão disciplina, logo a compreensão de interdisciplinaridade passa necessariamente pelo entendimento de disciplina. O princípio positivista se norteia na divisão do conhecimento em áreas específicas, a fim de promover uma profundidade maior em uma área mais restrita do conhecimento, assim o termo disciplina

  15. Charles Sanders Peirce: ciência enquanto semiótica

    Directory of Open Access Journals (Sweden)

    Lauro Frederico Barbosa da Silveira

    1989-01-01

    Full Text Available O diagrama do signo, quando aplicado no entendimento da ciência, dá lugar a uma correlação original entre abdução, dedução e indução. A união da abdução e da dedução consiste numa Forma geral de possibilidade lógica. Enquanto que a indução estabelece, no decorrer da experiência, a razão de freqüência no universo dos fatos das conseqüências previstas na representação geral. Como uma construção formal, a ciência enquanto semiótica sustenta-se, mesmo tendo por objeto um universo do puro acaso. Todavia, no interior do conjunto total do sistema filosófico de Peirce, a ciência só adquire significado se corresponder à realidade da Natureza. A garantia desta correspondência estatisticamente relevante seria o fato de o instinto humano pertencer ao mesmo estágio de evolução do universo todo.

    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. EDUCAÇÃO ESCOLAR ENQUANTO UNIDADE SIGNIFICADO SOCIAL/SENTIDO PESSOAL

    Directory of Open Access Journals (Sweden)

    Andréa Maturano Longarezi

    2013-04-01

    Full Text Available O artigo analisa as condições objetivas para efetivação de uma educação escolar que se constitua em processo de humanização pela unidade significado social/sentido pessoal. Tal discussão se alicerça sob as bases do materialismo histórico-dialético presente nas teorias histórico-cultural e da atividade. O processo de humanização, nas condições epistemológicas tratadas, pressupõe a unidade significação/sentido. A chave para a compreensão das possibilidades de uma educação escolar enquanto unidade significado/sentido encontra-se na relação dialética entre educaçãodesenvolvimento-atividade. Em se tratando de educação escolar, sua função humanizadora se concretiza pela via do desenvolvimento integral dos estudantes, o que implica o desenvolvimento de um tipo especial de pensamento que somente a escola poderá formar: o pensamento teórico. Pela apropriação das produções humano-genéricas para-si, no sentido tratado por Heller e Duarte, a escola contribuirá para a constituição de individualidades para-si. Esse é o caminho para a unidade, porque por ele, os sentidos poderão aproximar-se das significações sociais, condição sine qua non para humanização, enquanto processo de desalienação da sociedade. O desenvolvimento da atividade psíquica do homem que permita uma imersão na realidade operando mentalmente com princípios teóricos, podendo pensar e agir sobre a mesma com base nas produções humano-genéricas para-si é que possibilitará aproximar o indivíduo da coletividade, constituir-se humano em sociedade, isso pela via da unidade significado/sentido. Essa convergência encontra-se no campo conceitual da atividade, entendida no sentido tratado por A. N. Leontiev. Se é pela atividade que o homem se desenvolve e é nela que objeto e motivo coincidem, o sentido só se encontrará no significado se constituir-se em atividade. A educação escolar tem papel fundamental neste processo porque a ela

    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.

    Sílvia Helena Valente

    2000-03-01

    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.

  2. Educação, trabalho e proletarização: o professor enquanto trabalhador docente

    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.

    2011-10-01

    Full Text Available http://dx.doi.org/10.5007/2175-7917.2011v16n2p41 O objetivo do presente trabalho é descrever, discutir e analisar o surgimento do conto enquanto gênero de ficção, tendo como ponto de partida uma reflexão a respeito de Review of Twice-Told Tales, resenhas críticas de Edgar Allan Poe sobre os contos de um de seus contemporâneos, o escritor Nathaniel Hawthorne. Em tais textos, Poe apresenta a teoria da unidade de efeito, juntamente com a tese de que o conto poderia ser o veículo apropriado para a expressão máxima dos talentos de um artista. Além disso, será analisado o contexto literário norte-americano de princípios do século XIX, período no qual Poe produziu sua obra e que assistiu à consolidação do conto enquanto gênero ficcional. Neste sentido, serão abordados alguns aspectos do referencial teórico existente sobre narrativas curtas, a fim de problematizar alguns aspectos suscitados pela análise de Poe. Por último, serão feitas algumas considerações a respeito das ressonâncias de Poe na crítica literária, considerando que Mário de Andrade, Machado de Assis e Julio Cortázar retomam, rediscutem e reelaboram algumas noções propostas por Poe a respeito do conto.

  4. Busca de estruturas em grandes escalas em altos redshifts

    2003-08-01

    A busca por estruturas em grandes escalas (aglomerados de galáxias, por exemplo) é um ativo tópico de pesquisas hoje em dia, pois a detecção de um único aglomerado em altos redshifts pode por vínculos fortes sobre os modelos cosmológicos. Neste projeto estamos fazendo uma busca de estruturas distantes em campos contendo pares de quasares próximos entre si em z Â3 0.9. Os pares de quasares foram extraídos do catálogo de Véron-Cetty & Véron (2001) e estão sendo observados com os telescópios: 2,2m da University of Hawaii (UH), 2,5m do Observatório de Las Campanas e com o GEMINI. Apresentamos aqui a análise preliminar de um par de quasares observado nos filtros i'(7800 Å) e z'(9500 Å) com o GEMINI. A cor (i'-z') mostrou-se útil para detectar objetos "early-type" em redshifts menores que 1.1. No estudo do par 131046+0006/J131055+0008, com redshift ~ 0.9, o uso deste método possibilitou a detecção de sete objetos candidatos a galáxias "early-type". Num mapa da distribuição projetada dos objetos para 22 < i' < 25 observou-se que estas galáxias estão localizadas próximas a um dos quasares e há indícios de que estejam aglomeradas dentro de um área de ~ 6 arcmin2. Se esse for o caso, estes objetos seriam membros de uma estrutura em grande escala. Um outro argumento em favor dessa hipótese é que eles obedecem uma relação do tipo Kormendy (raio equivalente X brilho superficial dentro desse raio), como a apresentada pelas galáxias elípticas em z = 0.

    Full Text Available Na véspera da Conferência sobre desenvolvimento social em Copenhague (1995, o autor defende novas estratégias condizentes com uma axiologia do desenvolvimento. Para ele, não há desenvolvimento sem crescimento equilibrado dentro de cada país e nas relações Norte-Sul. Por outro lado, não se pode prescindir da ecologia. Finalmente o objetivo do desenvolvimento é o homem, sua cultura própria, seus valores universais: o direito à inserção produtiva e à participação enquanto cidadão, o que supõe um Estado democrático, regulador de uma economia mista. No plano jurídico, o autor sugere a criação de um foro internacional independente.On the eve of the International Social Conference in Copenhagen (1995, the author defends new strategies, suitable for a development axiology. According to him, there is no development without a balanced growth within each country and in the North-South relations. On the other hand, one cannot ignore ecology. Finally, the target of development is man, his own culture, his universal values: the right to a productive insertion and to the participation as a citizen. This pressuposes a democratic State, regulator of a mixed economy. At the juridic level, the author suggests the creation of an independent international forum.

    2014-05-01

    Full Text Available Stanislavski diz a seus atores: o Estúdio é para a Vida. Meyerhold acrescenta: o Teatro é a arte do Homem. Craig prevê um novo ator: Hoje ele personifica e interpreta; amanhã ele precisará representar e interpretar, e no terceiro dia ele irá criar. Grotowski e Barba aproveitam as forças do teatro oriental na epifania do Performer. Finalmente suprimindo a dependência do autor para criar a partir de si mesmo, o novo Performer obtém autonomia artística. Além disso: ao contrário de outros artistas, ele cria através de si mesmo, sem o uso de um meio. O papel do Diretor pressupõe uma fase intermediária: sem a base estável e unificadora do texto do Autor a autonomia arduamente adquirida pelo Performer poderia degenerar-se em individualismo centrado no ego. Segundo a neurociência, a ação precede a consciência. Fora de seu ato criativo como artista e dentro dele como matéria-prima, o Performer desafia limites. Ele é um sujeito-objeto, uma busca pelo Ser Humano não programado.

    2015-03-01

    Full Text Available Este texto versa sobre a supervisão enquanto dispositivo, ao apresentar o quadro teórico-conceitual que norteou a atuação e sua metodologia. Ao se debruçar sobre três campos de estágio, explicita o desafio de promover não apenas a saúde do trabalhador de saúde, mas, também, construir uma práxis questionadora da relação universidade-sociedade e formação. A partir da narrativa docente do estágio profissional em Psicologia do Trabalho, dimensiona-se como se constituiu a pesquisa-intervenção em bases interdisciplinares capazes de deslocar o saber centrado no expert para tencionar ações de coletivos transformadores, que, mediante a aproximação e o diálogo, oportunizassem o forjar de solidariedades e cooperação. Elementos profícuos para a ressignificação dessas esferas foram: a construção do diagnóstico institucional vinculado à demanda e o dispositivo supervisão, capaz de produzir narrativas originais para construir experiências de protagonização – correspondentes aos princípios da Política de Humanização.

  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.

    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.

    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.

  11. Preferência musical e busca de sensações entre jovens

    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.

Nessa direção, interpreta o filme como um discurso inserido no debate de sua época, de constituição do Brasil enquanto nação, que permeava várias dimensões da vida e do pensamento brasileiro nos anos 20-30 do século passado. Em consonância com o que se discutia na literatura e nas artes plásticas, o filme de Reis é cuidadosamente montado, utilizando-se para isso inúmeras cenas de filmes anteriores seus, no sentido de explicitar visualmente uma nação não em vias de constituição, mas, ao contrário, com seu território pacificado no interior, o que lhe daria estatuto de civilidade e, portanto, de uma nação inserida do processo civilizatório, ao mesmo tempo em que segura em suas fronteiras, pela presença visual incessante e inquestionável das instituições fundantes do Estado moderno, a família e o Estado, este último por meio de suas reconhecíveis instituições: a escola, a polícia e o exército, entre outras, realidade muito diferente de sua efetividade prática na época.This article analyses the movie Ao Redor do Brasil, from Thomaz Reis, taking as theoretical main references Paulo Arantes's, 'O sentido da formação', and Foucault's 'A ordem do discurso'.

In parallel do what was being discussed in literature and plastic arts, the movie is carefully assembled, using several scenes from Reis's previous movies to visually denote a Nation, not in its way to consolidate itself, but with a countryside already pacified, which would give it a label of civility, therefore

    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.

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.

    Full Text Available EXPERIÊNCIA E OBJETIVOS: Foram avaliados os riscos da contaminação de propofol 2%, remifentanil e pantoprazol e os efeitos desses agentes in vitro no crescimento de agentes infecciosos comuns em unidades de terapia intensiva. MÉTODOS: Para a detecção do risco de contaminação, foram testados agentes preparados para uso imediato em condições de unidade de terapia intensiva. Também foram investigados os efeitos desses três agentes no crescimento bacteriano. Os agentes foram preparados nas concentrações utilizadas na unidade de terapia intensiva e inoculados com patógenos comuns; em seguida, foram incubados a 4ºC, 22ºC e 36ºC. Foram obtidas subculturas a 0, 2, 4 e 8 h e avaliadas as contagens de colônias. Foram determinados os valores de concentração inibitória mínima para todos os agentes a 4ºC, 22ºC e 36ºC. RESULTADOS: Não foi observado crescimento nos agentes preparados na unidade de terapia intensiva. Propofol tendeu a suportar o crescimento, enquanto que remifentanil inibiu o crescimento bacteriano. O efeito de pantoprazol foi variável, dependendo com a bactéria testada. Nenhum dos agentes demonstrou atividade antibacteriana nas concentrações máximas que podem ser alcançadas no sangue dos pacientes. CONCLUSÃO: Propofol sustenta vigorosamente o crescimento dos microrganismos testados, o que não ocorre com remifentanil e pantoprazol. Portanto, é importante que sejam praticadas técnicas assépticas rígidas na preparação de propofol.

Enquanto Calliott defende uma perspectiva holista de ética ambiental, na qual o valor moral da ação depende de quanto ela constribui para o bem da comunidade bioética em sua totalidade, Taylor apresenta como moralmente relevantes as ações que contribuem para promover ou proteger o "bem próprio" de cada entidade viva individual. O objetivo deste estudo é analidar ambas as teorias e indicar qual delas mais se aproxima de um ideal de ética ambiental.

Em primeiro lugar, tentarei discutir o atual modelo de formação docente em Educação Física e abordar a importância da prática como instrumento de análise e a reflexão do professor como alternativa ao paradigma dominante da raciona-idade técnica. Em segundo lugar, tratarei da necessidade de se construir uma nova concepção da prática docente que eleja a dimensão reflexiva como componente fundamental da atividade do professor. E, finalmente, abordarei a questão da função social do professor como intelectual transformador no interior da escola e da universidade. PALAVRAS-CHAVE: Formação de professores – Educação Física – Educação The main idea of this article is to discuss the Physical Education teachers’ formation from a teacher’ s conception as an intelectual – reflective – transformer. First I will try to discuss the current model of the Physical Education teachers’ formation and to approach the importance of the pratice as a teacher’s instrument of analysis and reflection as an alternative to the dominant paradigm of the technic rationality. Second, I will discuss the necessity of construction of a new conception of the teacher’s pratice which selects the reflective dimension as an essencial component of the teacher’s pratice. And finally, I will present the teacher’s social function as a transformer intelectual inside the school and the university. KEY WORDS: Teacher’s formation – physical education – education

A liberdade para empreender essa busca somente é possível com o advento da proposta de novos modelos de tratamento, em especial o de se acompanhar a série de imagens do inconsciente, sejam elas pintadas, modeladas, encenadas ou escritas. O método de conscientizar as palavras, empregado nessa busca pela língua original, encontra-se, portanto, inextricavelmente unido à novidade, na época, de se tratar as pessoas em locais que não cerceiam a liberdade e que incentivam a livre expressão.

    NERSC recently undertook a project to access and analyze Secure Shell (SSH) related data. This includes authentication data such as user names and key fingerprints, interactive session data such as keystrokes and responses, and information about noninteractive sessions such as commands executed and files transferred. Historically, this data has been inaccessible with traditional network monitoring techniques, but with a modification to the SSH daemon, this data can be passed directly to intrusion detection systems for analysis. The instrumented version of SSH is now running on all NERSC production systems. This paper describes the project, details about how SSH was instrumented, and the initial results of putting this in production.

    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.

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.

Caracterizada como uma pesquisa qualitativa e descritiva procurou inicialmente explorar o cenário internacional da área de Representação Descritiva e sua relação com a Recuperação da Informação. Inserida nos estudos de Organização da Informação, traz conceitos relativos aos catálogos, suas definições e um breve histórico. A partir dos questionamentos de Borgman (1986, 1996 investigou a literatura publicada em revistas centrais da Ciência da Informação acerca dos OPACs, no intervalo de 1996 e 2010. Utiliza como framework conceitual a Teoria Bibliográfica de Svenonius (2000, que compreende a organização e representação da informação em um contexto histórico-filosófico e desenvolve os fundamentos relacionados aos objetivos bibliográficos. Utilizou a literatura como corpus empírico indireto para perceber quais objetivos bibliográficos estavam subjacentes a estes estudos e analisando-os à luz da Teoria Bibliográfica. Conclui-se que os objetivos bibliográficos estavam subjacentes às pesquisas sobre catálogos no período estudado, mais especificamente o objetivo de organizar. Sugere que a partir do quadro conceitual desenhado para este estudo acrescente-se uma nova camada de conceitos que explorem as linguagens de assunto em termos de objetivos bibliográficos, compilando suas características, princípios relacionados e ampliando o corpus de análise, investigando os objetivos que tangenciam estas linguagens.

  1. 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.

Adotou-se como objeto, as manifestações da criança acerca de suas experiências dentro do contexto de uma pré-escola, não por meio do discurso adulto, mas sim pela fala, pelo olhar, pelos gestos, pelas histórias, pelos desenhos, de quem a vivencia no momento - a criança. Desse modo, apoiando-se nos pressupostos teóricos da Sociologia da Infância, buscou-se examinar as manifestações expressivas das crianças com seus pares, adotando os seguintes objetivos específicos: apreender e analisar as concepções das crianças acerca da instituição de Educação Infantil que frequentam; apontar e refletir sobre possíveis direções que propiciem um ambiente agradável que as cuidem e eduquem respeitando mais os seus desejos, as suas necessidades e particularidades. Para tanto, o estudo com abordagem qualitativa, teve como participantes crianças que se encontram na faixa etária entre o quinto e o sexto ano de vida, de um agrupamento de Pré II, de uma instituição de Educação Infantil no município de Corumbá-MS. Nesse sentido, foram determinados os seguintes procedimentos metodológicos julgados condizentes para a busca das percepções dos sujeitos pesquisados: observação participante (com registros no diário de campo; conversa informal (gravada em áudio; desenhos (com direcionamentos temáticos produzidos pelas crianças; visita guiada (gravada em áudio; e a história para completar (gravada em áudio.

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.

    Full Text Available O campo científico da comunicação vive uma verdadeira encruzilhada: ou se perde no empirismo do estudo dos media; ou, numa recusa a tal empirismo, se lança numa busca teórica voraz, o que ameaça, por vastidão e frouxidão, seu estatuto científico, inclusive por colocar em suspenso a cientificidade dos estudos realizados no campo. 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.

Aborda as características desse processo, entre elas as etapas do projeto de pesquisa em que realizam a busca de informação, quem geralmente faz esta atividade, quais os tipos de fontes utilizadas assim como o local preferido para a realização da busca de informação. Foi aplicado um questionário semi-estruturado, aplicado através de uma entrevista, que possibilitou traçar um perfil do comportamento de busca de informação realizado pelos professores/pesquisadores, quais as características desse processo e as barreiras encontradas. Constata-se que os professores/pesquisadores utilizam preferencialmente as bases de dados em CD-ROM ou on-line para realizar a busca de informações, não utilizando-se mais os abstracts impressos. Os periódicos impressos nacionais e internacionais possuem boa aceitação entre os professores/pesquisadores, o que não ocorre com os periódicos eletrônicos, ainda pouco conhecidos. Os serviços propiciados pela internet são muito utilizados, principalmente o correio eletrônico e os diretórios de busca, o que não ocorre com as listas de discussão. As fontes pessoais são utilizadas para intercâmbio de conhecimentos entre pesquisadores não somente da própria instituição como de outras. As barreiras encontradas na busca de informação foram categorizadas em Barreiras Pessoais, Barreiras Institucionais e Barreiras do Ambiente ou da Tecnologia.

Entende-se a intersemiose como a mistura das linguagens, sendo a hibridização sua característica principal. O conceito de tradução, apropriado de Jackobson, engloba a transmutação do signo dentro de uma língua (intralingual, de uma língua para outra (interlingual, ou a tradução propriamente dita, e entre uma linguagem e outra (intersemiótica. Outro conceito incorporado na pesquisa foi a tradução intrassemiótica, dentro da matriz visual, para colaborar com a análise da linguagem visual, que tem a forma como eixo de inteligibilidade e a figura como representação do visível.Resultados: O comportamento intersemiótico dos dois buscadores demonstrou-se, de maneira geral, satisfatório.Conclusões: O aprendizado da linguagem pela máquina faz diferença entre os níveis de tradução, entre o igual e o parecido, sobre o princípio de similaridade da forma, seja de uma língua, seja de uma imagem.

    Horner, Andrew B.; Beauchamp, James W.

    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.

    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.

    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.

La novela traza un imaginario de la región relacionado intertextualmente con otras representaciones históricas y literarias de este espacio que se revisan. Dichas representaciones, procedentes principalmente de la narrativa europea promueven su definición literaria y política que la novela desnaturaliza. La tierra del fuego rememora los modos con que Inglaterra escribe y describe la Patagonia en el siglo XIX como espacio subalterno, y recuerda también la problemática inscripción de este territorio en la cartografía política nacional. La novela da cuenta de la geográfica imaginaria de la región como una construcción ideológica y discursiva que se reconfigura desde distintas perspectivas: personaje narrador, prensa escrita, y demás personajes para legitimar la presencia e intervención de los ingleses en el territorio, sin dejar de lado las estrategias que describe y narra la naturaleza patagónica y la cultura de los habitantes autóctonos de la región.

    The Visible Integral-Field Replicable Unit Spectrograph (VIRUS) instrument will be installed at the Hobby-Eberly Telescope† in the near future. The instrument will be housed in two enclosures that are mounted adjacent to the telescope, via the VIRUS Support Structure (VSS). We have designed the enclosures to support and protect the instrument, to enable servicing of the instrument, and to cool the instrument appropriately while not adversely affecting the dome environment. The system uses simple HVAC air handling techniques in conjunction with thermoelectric and standard glycol heat exchangers to provide efficient heat removal. The enclosures also provide power and data transfer to and from each VIRUS unit, liquid nitrogen cooling to the detectors, and environmental monitoring of the instrument and dome environments. In this paper, we describe the design and fabrication of the VIRUS enclosures and their subsystems.

    Manuel Vicente Ribeiro Veiga Junior

    Full Text Available Música se relaciona com religião de várias maneiras, quer nos sistemas de crença, quer no controle do poder. Ambas são universais da cultura. Como não temos conhecimento dos universais empíricos da própria música, o estudo abrangente de sua associação com o sagrado é um duplo desafio. Concentrando-se no homem e para entendê-lo melhor, optou-se pela busca de origens possivelmente comuns, um processo que não enfatiza os monumentos musicais das religiões propriamente ditas e dos caminhos de salvação, Ocidente e Oriente não esquecidos. A volta ao passado mais remoto, aos milênios em que sons humanamente organizados se articularam em símbolos, é o ponto crucial. Os ângulos, as concepções, as revisões e os métodos de abordagem da parca evidência disponível constituem as variações de nosso título. Do ponto de vista etnomusicológico, as questões que ressurgem não são sobre que tipo de música foi feita, nem sobre os processos pelo quais a música foi primeiramente criada, mas as razões, isto é, sua necessidade de existência (suas funções.

    This essay proposes that our understanding of medical instruments might benefit from adding a more forthright concern with their immediate presence to the current historical focus on simply decoding their meanings and context. This approach is applied to the intriguingly tricky question of what...... actually is meant by a "medical instrument." It is suggested that a pragmatic part of the answer might lie simply in reconsidering the holdings of medical museums, where the significance of the physical actuality of instruments comes readily to hand....

    Full Text Available Surgical instruments are the group of tools used in surgical procedures. They are very expensive and sophisticated. Consequently, a standardized and meticulous care is essential; they should go through the decontamination, cleaning and sterilization process. These instruments are designed in order to provide surgeons with tools that help them to perform a basic surgical procedure; there are multiple variations and the design depends on their function. This paper aims at showing all surgical instruments that can be used in an operating room during surgery and are not generally included in the medical literature.

    Cooks, R. G.; Hoke, S. H., II; Morand, K. L.; Lammert, S. A.

    1992-09-01

    Developments in mass spectrometry instrumentation over the past three years are reviewed. The subject is characterized by an enormous diversity of designs, a high degree of competition between different laboratories working with either different or similar techniques and by extremely rapid progress in improving analytical performance. Instruments can be grouped into genealogical charts based on their physical and conceptual interrelationships. This is illustrated using mass analyzers of different types. The time course of development of particular instrumental concepts is illustrated in terms of the s-curves typical of cell growth. Examples are given of instruments which are at the exponential, linear and mature growth stages. The prime examples used are respectively: (i) hybrid instruments designed to study reactive collisions of ions with surfaces: (ii) the Paul ion trap; and (iii) the triple quadrupole mass spectrometer. In the area of ion/surface collisions, reactive collisions such as hydrogen radical abstraction from the surface by the impinging ion are studied. They are shown to depend upon the chemical nature of the surface through the use of experiments which utilize self-assembled monolayers as surfaces. The internal energy deposited during surface-induced dissociation upon collision with different surfaces in a BEEQ instrument is also discussed. Attention is also given to a second area of emerging instrumentation, namely technology which allows mass spectrometers to be used for on-line monitoring of fluid streams. A summary of recent improvements in the performance of the rapidly developing quadrupole ion trap instrument illustrates this stage of instrument development. Improvements in resolution and mass range and their application to the characterization of biomolecules are described. The interaction of theory with experiment is illustrated through the role of simulations of ion motion in the ion trap. It is emphasized that mature instruments play a

    Full Text Available Este relato é um recorte de extensa pesquisa que buscou identificar a rede de representações sociais (RS estabelecida em torno do ser mulher na família. Centra-se na questão da conjugalidade e busca verificar se a vivência conjugal e familiar sofreu modificações significativas num intervalo de aproximadamente 3 décadas. Foram realizadas 20 entrevistas narrativas, semiestruturadas, com mulheres de estrato socioeconômico médio e baixo: 10 que tiveram filhos nos anos 1960 (1ª geração e 10 nos anos 1990 (2ª geração, filhas das primeiras. A entrevista permitiu às participantes falarem de suas experiências e práticas cotidianas em relação aos contextos familiar e conjugal. Visando agregar procedimentos complementares, os dados foram organizados/analisados a partir de adaptação do método fenomenológico para investigação psicológica e do software Alceste. Os resultados evidenciaram tanto continuidades quanto rupturas entre as gerações, podendo ser destacadas mudanças expressivas de uma geração à outra em relação a importantes aspectos do relacionamento conjugal como: a manutenção do casamento que deixa de ser o objetivo principal; as relações conjugais, de forma geral, tornam-se mais abertas; há redução de interdições em relação à mulher; e o investimento feminino no casamento passa a dividir espaço com o maior envolvimento masculino.This report is an extract of an extensive research which attempted to identify the social representation (SR net established around being a woman in the family.

    Werner, K

    2010-01-01

    We describe telescopes and instruments that were developed and used for astronomical research in the ultraviolet (UV) and extreme ultraviolet (EUV) regions of the electromagnetic spectrum. The wavelength ranges covered by these bands are not uniquely defined. We use the following convention here: The EUV and UV span the regions ~100-912 and 912-3000 Angstroem respectively. The limitation between both ranges is a natural choice, because the hydrogen Lyman absorption edge is located at 912 Angstroem. At smaller wavelengths, astronomical sources are strongly absorbed by the interstellar medium. It also marks a technical limit, because telescopes and instruments are of different design. In the EUV range, the technology is strongly related to that utilized in X-ray astronomy, while in the UV range the instruments in many cases have their roots in optical astronomy. We will, therefore, describe the UV and EUV instruments in appropriate conciseness and refer to the respective chapters of this volume for more technic...

    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.

    2014-06-01

    Now that the field of performing arts medicine has been in existence for over three decades, we are approaching a key point: we should start to see more articles that bring together the data that have been collected from several studies in order to draw more robust conclusions. Review articles and their more structured relative, the meta-analysis, can help to improve our understanding of a particular topic, comparing and synthesizing the results of previous research that has been done on that subject area. One way this could be done would be to review the research that has been carried out on the performance-related problems associated with playing a particular instrument or group of instruments. While I am not going to do that myself, I hope that others will. In this editorial, I will do a very selective review of the playing-related musculoskeletal disorders (PRMDs) associated with one instrument group (the keyboard instruments), focusing on the most played instrument in that group (the piano;).

    In this Chapter we review the challenges of, and opportunities for, 3D spectroscopy, and how these have lead to new and different approaches to sampling astronomical information. We describe and categorize existing instruments on 4m and 10m telescopes. Our primary focus is on grating-dispersed spectrographs. We discuss how to optimize dispersive elements, such as VPH gratings, to achieve adequate spectral resolution, high throughput, and efficient data packing to maximize spatial sampling for 3D spectroscopy. We review and compare the various coupling methods that make these spectrographs ``3D,'' including fibers, lenslets, slicers, and filtered multi-slits. We also describe Fabry-Perot and spatial-heterodyne interferometers, pointing out their advantages as field-widened systems relative to conventional, grating-dispersed spectrographs. We explore the parameter space all these instruments sample, highlighting regimes open for exploitation. Present instruments provide a foil for future development. We give an...

But the issuers remain companies incorporated under Company Law of 1990. Such dual regulations need increased attention in order to observe the legal status of the issuers/companies and financial instruments/shares. Romanian legislator has chosen to implement in Capital Market Law special rules regarding the administration of the issuers of financial instruments, not only rules regarding admitting and maintaining to a regulated market.

    Davidson, W. F.

    1986-01-01

    An electronics circuit which provides for the recording of instrumentation data on an optical disk is disclosed. The optical disk is formatted in a spiral format instead of concentric tracks. The spiral format allows data to be recorded without the gaps that would be associated with concentric tracks. The instrumentation system provides each channel with a program instrumentation amplifier, a six pole lowpass switched capacitor filter, a sample and hold amplifier, and a digital to analog converter to provide automatic offset capability. Since each channel has its own components, simultaneous samples of every channel can be captured. All of the input signal's channel variables can be captured. All of the input signal's channel variables can be changed under software control without hardware changes. A single board computer is used for a system controller.

  2. Virtual Sensor Test Instrumentation

    Wang, Roy

    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 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.

    2011-01-01

    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.

    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.

    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

    For the stable high-luminosity operation and luminosity increase, the electron and positron storage rings of the KEK B-Factory (KEKB) is equipped with various beam instrumentations, which have been working well since the start of the commissioning in December, 1998. Details and performance of the beam-position monitor system based on the spectrum analysis using DSPs, the turn-by-turn BPM with four-dimensional function available for measurements of the individual bunch position, phase and intensity, the parametric beam-DCCTs designed so as to avoid the magnetic-core-selection problems for the parametric flux modulation, the bunch-by-bunch feedback system indispensable to suppress the strong multibunch instabilities in KEKB, the various optical beam diagnostic systems, such as synchrotron radiation interferometers for precise beam-size measurement, the tune meters, the bunch length monitors and the beam-loss monitors are described. Delicate machine tuning of KEKB is strongly supported by these instrumentations.

  3. Solar radioastronomical instruments

    Science.gov (United States)

    Gonze, R.

    Instruments for detecting and recording the radio emissions of the sun are required to cover the entire electromagnetic spectrum, measure intensity and polarization, as well as the region of the emissions, and display high resolution in both space and time. Radioheliographic images of the sun are made from wavelengths outside of the visible, and yield images based on a grid of relative intensities of varying fineness of resolution. Radioelectric isophote contours can be generated using radiotelescopes at specific receptive frequencies, and interferometric techniques permit the employment of multiple paraboloidal receivers to construct a synthetic image of greater resolution than possible with a single antenna. Dynamic radiospectrography is used to examine transitory solar radio emissions where fine structures are produced in frequency bands covering at least an octave. Multichannel radiospectrographic equipment with many receptors tuned to discrete frequencies and regularly adjusted permits coverage of broad frequency bands, with digital control to augment the dynamics of the instruments.

    The physician has, for whatever reasons, diminished his or her level of involvement on the team dedicated to developing, refining, and evaluating medical technology. As a result, the challenge confronting the physician and the technology development team today is to orchestrate a team structure that will ensure the greatest input and commitment from physicians and other professionals during current and future technology development. The charges of cost escalation and dehumanization in our system of health care delivery will also be discussed, as will the lack of, or confusion about, access to data concerning cost of a given instrument, and fuzzy semantics and perspectives on technology and instrumentation. The author suggests answers to, or means to ameliorate, the problems.

    One of the tasks specified in the NASA Langley controlled impact demonstration (CID) work package was to furnish dynamic instrumentation sensors. The types of instrumentation sensors required were accelerometers for aircraft structural loads measurements, seat belt load cells to measure anthropomorphic dummy responses to the aircraft impact, and strain gage bending bridges to measure the aircraft fuselage and wing bending during impact. The objective in the selection of dynamic instrumentation for the CID was to provide 352 of the highest quality transducers and remain within budget allocation. The transducers that were selected for the CID evaluation process were each subjected to rigorous laboratory acceptance tests and to aircraft fuselage section drop tests at the LaRC Impact Dynamics Research Facility. Data compiled from this series of tests showed the selected transducers to be best suited for the CID mission requirement. The transducers installation technique on the airframe proved successful. The transducer quality assurance was guaranteed through rigorous acceptance testing. Data acquired was 97.0%.

    2011-06-01

    We describe the design of an instrument that can fully implement a new nanopatterning method called ice lithography, where ice is used as the resist. Water vapor is introduced into a scanning electron microscope (SEM) vacuum chamber above a sample cooled down to 110 K. The vapor condenses, covering the sample with an amorphous layer of ice. To form a lift-off mask, ice is removed by the SEM electron beam (e-beam) guided by an e-beam lithography system. Without breaking vacuum, the sample with the ice mask is then transferred into a metal deposition chamber where metals are deposited by sputtering. The cold sample is then unloaded from the vacuum system and immersed in isopropanol at room temperature. As the ice melts, metal deposited on the ice disperses while the metals deposited on the sample where the ice had been removed by the e-beam remains. The instrument combines a high beam-current thermal field emission SEM fitted with an e-beam lithography system, cryogenic systems, and a high vacuum metal deposition system in a design that optimizes ice lithography for high throughput nanodevice fabrication. The nanoscale capability of the instrument is demonstrated with the fabrication of nanoscale metal lines.

  8. FHR Process Instruments

    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

    The past year's contribution from Dr. Kaukler's experimental effort consists of these 5 parts: a) Construction and proof-of-concept testing of a novel shearing plate viscometer designed to produce small shear rates and operate at elevated temperatures; b) Preparing nonlinear polymeric materials to serve as standards of nonlinear Theological behavior; c) Measurements and evaluation of above materials for nonlinear rheometric behavior at room temperature using commercial spinning cone and plate viscometers available in the lab; d) Preparing specimens from various forms of pitch for quantitative comparative testing in a Dynamic Mechanical Analyzer, Thermal Mechanical Analyzer; and Archeological Analyzer; e) Arranging to have sets of pitch specimens tested using the various instruments listed above, from different manufacturers, to form a baseline of the viscosity variation with temperature using the different test modes offered by these instruments by compiling the data collected from the various test results. Our focus in this project is the shear thinning behavior of ZBLAN glass over a wide range of temperature. Experimentally, there are no standard techniques to perform such measurements on glasses, particularly at elevated temperatures. Literature reviews to date have shown that shear thinning in certain glasses appears to occur, but no data is available for ZBLAN glass. The best techniques to find shear thinning behavior require the application of very low rates of shear. In addition, because the onset of the thinning behavior occurs at an unknown elevated temperature, the instruments used in this study must provide controlled low rates of shear and do so for temperatures approaching 600 C. In this regard, a novel shearing parallel plate viscometer was designed and a prototype built and tested.

    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 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.

    The Astronomical Instrumentation System Markup Language (AISML) is an Extensible Markup Language (XML) based file format for maintaining and exchanging information about astronomical instrumentation. The factors behind the need for an AISML are first discussed followed by the reasons why XML was chosen as the format. Next it's shown how XML also provides the framework for a more precise definition of an astronomical instrument and how these instruments can be combined to form an Astronomical Instrumentation System (AIS). AISML files for several instruments as well as one for a sample AIS are provided. The files demonstrate how AISML can be utilized for various tasks from web page generation and programming interface to instrument maintenance and quality management. The advantages of widespread adoption of AISML are discussed.

    The international Muon Ionization Cooling Experiment (MICE) will carry out a systematic investigation of ionization cooling of a muon beam. As the emittance measurement will be done on a particle-by-particle basis, sophisticated beam instrumentation is needed to measure particle coordinates and timing vs RF. A PID system based on three time-of-flight stations, two Aerogel Cerenkov detectors and a KLOE-like calorimeter has been constructed in order to keep beam contamination ($e, \\pi$) well below 1%. The MICE time-of-flight system will measure timing with a resolution better than 70 ps per plane, in a harsh environment due to high particle rates, fringe magnetic fields and electron backgrounds from RF dark current.

    1994-03-01

    This paper describes the design and operation of a fast, flexible, non-contact, eye-safe laser ranging instrument useful in a variety of industrial metrology situations, such as in-process machining control and part inspection. The system has variable computer-controlled standoff and depth of field, and can obtain 3-D images of surfaces within a range of from 1.5 ft to almost 10 ft from the final optical element. The minimum depth of field is about 3.5 in. at 1.5 ft and about 26 in. at the far range. The largest depth of field for which useful data are available is about 41 in. Resolution, with appropriate averaging, is about one part in 4000 of the depth of field, which implies a best case resolution for this prototype of 0.00075 in. System flexibility is achieved by computer controlled relative positioning of optical components.

  6. Portable musical instrument amplifier

    Christian, David E. (Danbury, CT)

    1990-07-24

    The present invention relates to a musical instrument amplifier which is particularly useful for electric guitars. The amplifier has a rigid body for housing both the electronic system for amplifying and processing signals from the guitar and the system's power supply. An input plug connected to and projecting from the body is electrically coupled to the signal amplifying and processing system. When the plug is inserted into an output jack for an electric guitar, the body is rigidly carried by the guitar, and the guitar is operatively connected to the electrical amplifying and signal processing system without use of a loose interconnection cable. The amplifier is provided with an output jack, into which headphones are plugged to receive amplified signals from the guitar. By eliminating the conventional interconnection cable, the amplifier of the present invention can be used by musicians with increased flexibility and greater freedom of movement.

    The use of nickel-titanium rotary instrument systems has gained popularity over the past 10 years. One of these instrument systems is the LightSpeed (LightSpeed Technology, Inc, San Antonio, TX). One drawback for all nickel-titanium rotary instruments is the incidence of instrument separation. The purpose of this study was to evaluate the incidence of nonretrievable instrument separation using the LightSpeed system in a clinical setting. A total of 3543 canals were treated over a 24 month period and during that time, 46 LightSpeed instruments were separated and found to be nonretrievable, resulting in a separation rate of 1.30%. This rate was lower than previous reported studies.

    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.

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. CONCLUSÃO: Esses casos mostraram que a busca às cegas com os dedos na boca de bebês durante o choro não é somente uma manobra perigosa, mas também pode ser fatal.OBJECTIVE: In stressful situations, people usually use finger sweep to remove pharyngeal foreign bodies from the mouth.

    The recent successes of the Galileo solid-state imaging (SSI) experiment at the Moon and Gaspra show the utility of multispectral imaging of planetary objects. 'Clementine' is the planetary community's 'code name' for the SDIO (Space Defense Initiative Organization), mission to the Moon and the asteroid Geographos. This mission is designed as a long term stressing test on sensors and space systems developed for SDIO. In the course of this test Clementine will obtain science data using a varied and powerful array of remote sensing instruments which were developed by or for Lawrence Livermore National Laboratory in Livermore, California. Clementine carries five cameras, one for navigation and four for science experiments. In addition, a laser ranger is included which will serve as a laser altimeter. The Clementine cameras cover a wider range of spatial resolutions and wavelength range than did Galileo and are almost ideally suited to mapping of mafic rock types as are present on the Moon and expected at Geographos. Calibration of the cameras will occur at the sensor calibration laboratory at LLNL. In flight calibrations, using standard stars and other standards should improve the stated accuracies. Signal-to-noise ratios (SNRs) include the following noise sources: shot noise, calibration error, digitization noise, readout noise, and frame transfer noise (where applicable). The achieved SNRs are a balance between detector saturation and acceptable image smear. The 'worst' case uses the longest possible integration times.

  2. Halo vest instrumentation

    1996-05-01

    The halo vest is a head and neck immobilization system that is often used on patients that are recovering from cervical trauma or surgery. The halo vest system consists of a rigid halo that is firmly attached to the skull, an upright support structure for stabilization and immobilization, and a torso-enveloping vest. The main purpose of this study was to measure the forces that are carried by the halo-vest structure as the subject undergoes various activities of daily living and external loading for different vest designs. A tethered strain gage load cell based instrumentation system was used to take these load measurements on ten different subjects. Three different halo-vest systems were evaluated. The primary difference between the vests was the amount of torso coverage and the use of shoulder straps. The loads were measured, analyzed and used to compare the vests and to create a model of halo-vest-neck mechanics. Future applications of this technology to standalone data logging, pin-load measuring and biofeedback applications are discussed.

  3. Detectors for Tomorrow's Instruments

    2009-01-01

    Cryogenically cooled superconducting detectors have become essential tools for a wide range of measurement applications, ranging from quantum limited heterodyne detection in the millimeter range to direct searches for dark matter with superconducting phonon detectors operating at 20 mK. Superconducting detectors have several fundamental and practical advantages which have resulted in their rapid adoption by experimenters. Their excellent performance arises in part from reductions in noise resulting from their low operating temperatures, but unique superconducting properties provide a wide range of mechanisms for detection. For example, the steep dependence of resistance with temperature on the superconductor/normal transition provides a sensitive thermometer for calorimetric and bolometric applications. Parametric changes in the properties of superconducting resonators provides a mechanism for high sensitivity detection of submillimeter photons. From a practical point of view, the use of superconducting detectors has grown rapidly because many of these devices couple well to SQUID amplifiers, which are easily integrated with the detectors. These SQUID-based amplifiers and multiplexers have matured with the detectors; they are convenient to use, and have excellent noise performance. The first generation of fully integrated large scale superconducting detection systems are now being deployed. I will discuss the prospects for a new generation of instruments designed to take full advantage of the revolution in detector technology.

En este enfoque, la escucha clínica se inclinará a la forma como el sujeto cuenta y elabora su experiencia, de manera que una repentina sensación de extrañamiento o desrealización puede dar hogar a un enriquecimiento subjetivo. Este artículo se compara dos situaciones de perplejidad. La primera serie de escenas se refiere a Un trastorno de la memoria en la Acrópolis (Freud, 1936/1990, en lo cual un hombre transforma la perplejidad en un saber acerca de él. La segunda situación se refiere a las escenas del personaje Stephen Dedalus en Retrato del artista adolescente (Joyce, 1917/2006 que, en un episodio, vive sus propios sentimientos acerca de sí mismo y de otros como extraños para, en otro momento, tomar el extrañamiento como un método para trabajar el lenguaje. ¿Podemos extrañar la propia lengua, en el sentido de sentir a nosotros o a la lengua misma como extraña? En este caso, la extrañeza se convierte en un método de creación poética: se puede jugar con el lenguaje a través del desmontaje y montaje de las palabras para descubrir nuevos extrañamientos. El análisis de estas dos situaciones nos lleva a la distinción entre la ficción del caso creada por el psicoanalista y la ficción del personaje creado por el autor.

    A method has been developed for caging science instrumentation to protect from pyro-shock and EDL (entry, descent, and landing) acceleration damage. Caging can be achieved by immersing the instrument (or its critical parts) in a liquid and solidifying the liquid by cooling. After the launch shock and/or after the payload has landed, the solid is heated up and evaporated.

    Here we describe our ongoing efforts to develop high-performance and sensitive instrumentation for use in the search for extra-terrestrial intelligence (SETI). These efforts include our recently deployed Search for Extraterrestrial Emissions from Nearby Developed Intelligent Populations Spectrometer (SERENDIP V.v) and two instruments currently under development; the Heterogeneous Radio SETI Spectrometer (HRSS) for SETI observations in the radio spectrum and the Optical SETI Fast Photometer (OSFP) for SETI observations in the optical band. We will discuss the basic SERENDIP V.v instrument design and initial analysis methodology, along with instrument architectures and observation strategies for OSFP and HRSS. In addition, we will demonstrate how these instruments may be built using low-cost, modular components and programmed and operated by students using common languages, e.g. ANSI C.

El Estado impulsó la industrialización, la modernización agraria y la ampliación de la infraestructura productiva y los sectores sociales. Fue un ciclo estadocéntrico, basado en el enfoque estructuralista, agotado en los años setenta. Después de la crisis de la deuda en lo-s ochenta, se reemplazó por el enfoque neoliberal del Consenso de Washington, orientado a la estabilidad financiera, el mercado y la apertura externa, lo que daría lugar al desarrollo.

A tese central, ainda que como conclusão provisória, é que, num mundo fragmentado e secularizado, pessoas, especialmente jovens, buscam orientação de vida e fé em formas religiosas identificadas com o passado, pois estas ofereceriam segurança e proteção diante de uma sociedade e igreja cada vez mais secularizadas e sem um dossel sagrado determiná-las. Assim, analisamos a tendência pósmoderna de se voltar a costumes, liturgias e doutrinas mais rígidas ou conservadoras, justa e paradoxalmente no intuito de resistir à pós-modernidade ou à racionalidade moderna. Nosso estudo tem como pano de fundo o movimento da Toca de Assis e, até certo ponto, as teorias sociológicas de Peter Berger. Assim, a metodologia deste estudo é a sociológica.Palavras-chave: Igreja Católica; Jovens; Movimentos eclesiais.ABSTRACTThis article aims to present some sociological theories that can explain the present emergence of Catholic ecclesiastical movements of a “traditional” nature, which rescue religious life styles identified with the past, that is, with the Church before Vatican Council II. The central thesis, though inconclusive, is that, in a fragmented and secularized world, people, especially the young, would search for life guidance and faith in religious forms identified with the past, as they would offer security and protection in a society and in a church rendered more and more secular, and deprived of a sacred canopy to define them. Thus, it analyzes the post-modern trend to return to more rigid or conservative habits, liturgies and doctrines, precisely – and paradoxically – as a form of resistance to post-modernity or modern rationality. The article is based on the movement of Toca de Assis (St. Francis of Assisi’s Burrow Fraternity and, up to certain point, on Peter Berger’s sociological theories. Thus, the study methodology is sociological.Key words: Catholic Church; The young; Ecclesiastical movements.

  2. 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

When this creation is built in two possible levels of fiction, it generates a mythic-symbolic scene, whose structure is presented in the text as the ritual of going back to sacred origins, which is an endless ritual. Such an aspect can be situated in both human and discursive instances. Keywords: Culture. Guimarães Rosa. Symbolic level.

A busca por métodos para condicionar estas cerâmicas tem estimulado inúmeros trabalhos científicos. O tratamento da superfície cerâmica, a descontaminação da superfície e a escolha dos agentes de união e cimentação estão entre os itens considerados importantes. As pesquisas dos últimos cinco anos mostram que ainda não há um protocolo definido de cimentação, contudo os resultados apontam para uma associação de métodos para que a união adesiva seja obtida.The elimination of the glassy phase of dental ceramics made them resistant to fracture but also acid resistant, which makes it difficult in the latter case the adhesive resin cement. The search for methods to condition these ceramics has stimulated many scientific papers. The ceramic surface treatment, decontamination of the surface and the choice of coupling agents and cement are among the items considered important. Researches in the last five years show that there is still no established protocol for cement, but the results point to a combination of methods for the adhesive bond is obtained.

Esse trabalho objetiva resgatar o sujeito moderno de todas as influências cabíveis, provenientes da mídia, por meio das metáforas presentes na obra; e foi executado a partir da leitura do livro “o conto da ilha desconhecida”, com base em anotações e pesquisas feitas ao longo da leitura, e posteriormente, discussões a respeito das ideias presentes na obra. Percebeu-se que Saramago faz uma crítica implícita aos níveis da sociedade, utilizando personagens anônimos, mas com alto poder de decisão, que pode ser facilmente substituído por qualquer um de nós. Conclui-se que, apesar de pertencer a uma classe menos favorecida, em momento algum, deve-se desistir dos nossos sonhos e objetivos, obstáculos sempre existiram para nos fortalecer e nos preparamos para quando nos deparamos com problemas ainda maiores.

    Full Text Available No Brasil, a realização de interrupção legal de gestação consequente à violência sexual é permitida por lei. O objetivo deste estudo foi relatar vivências de mulheres após a violência sexual, no diagnóstico de gravidez, na busca pelo serviço de interrupção legal da gestação e durante a internação em um hospital universitário. Foi realizada pesquisa qualitativa com entrevistas semiestruturadas em dez mulheres de 18-38 anos e escolaridade ≥ 8 anos, após 1-5 anos da interrupção legal da gestação. As mulheres desconheciam o direito à interrupção legal da gestação, sentiram a violência sexual como experiência vergonhosa, mantiveram segredo e não procuraram qualquer atendimento imediato. O diagnóstico de gravidez provocou sentimentos de angústia e desejo de abortar. Para as mulheres que procuraram o setor de saúde suplementar as orientações foram precárias ou não aconteceram. O atendimento dos profissionais mostrou-se relevante para assimilação da experiência do aborto. É necessário divulgar o direito à interrupção legal da gestação e a existência de serviços que a realizam, e capacitar profissionais de saúde e segurança pública para atender esses casos.

    Full Text Available Tendo-se em vista a tendência da estabilidade das rotinas da contabilidade gerencial e a dificuldade da introdução prática de novas abordagens conceituais, este estudo tem como objetivo identificar características fundamentais de hábitos e rotinas da contabilidade gerencial. A pesquisa buscou estudar os hábitos e rotinas existentes, bem como novos hábitos e rotinas surgidos a partir da instalação de um processo de mudança nos sistemas de custos e preços de uma empresa comercial familiar de porte médio. Considerando a necessidade de entendimento da situação da empresa antes do processo de mudanças, durante o processo e após a implantação, optou-se pela metodologia de pesquisa–ação. A busca por respostas às questões levantadas durante as observações deu-se com base no arcabouço das teorias institucional e da contingência. Em relação aos resultados do caso estudado, destacam-se: 1. a análise dos impactos de contingências ambientais, tornando ineficazes os hábitos e rotinas de contabilidade gerencial existentes; 2. a dificuldade de mudança nos velhos hábitos e rotinas institucionalizados, empregados de forma inconsciente; 3. o emprego de diferentes estratégias para a institucionalização dos novos conceitos gerenciais.

Estas reflexões tiveram origem em uma experiência de estágio supervisionado na educação infantil do curso de Pedagogia, momento este caracterizado pelo encontro com as crianças pequenas e práticas educativas que marcam a vida das crianças e adultos que ali atuam. Diante disto, elegemos neste artigo algumas temáticas que marcaram este período e que consideramos importante para aprofundamento e reflexão na área da educação infantil. Esta experiência teve início na 7ª fase do curso de Pedagogia da UFSC com a habilitação em Educação Infantil, e teve como objetivo aproximar teoria e prática por meio da inserção em instituições de educação infantil públicas. Imersas no cotidiano da educação infantil, nos utilizamos das ferramentas pedagógicas de observação e registro, que orientaram, juntamente com a produção teórica sobre a educação infantil, as proposições na 8ª fase. Tendo como base um projeto que considera as crianças como referência da dinâmica das relações pedagógicas, tornando-as ponto de partida para a orientação das práticas educativa, elegemos três eixos norteadores para refletir sobre nossa inserção em campo, são elas: estágio, prática pedagógica e participação infantil.

    Beneduzi, Luís Fernando

    2015-01-01

    Full Text Available Na década seguinte à Primeira Guerra Mundial, observa-se na realidade latino-americana uma forte transformação na percepção da Europa enquanto modelo de civilização. Novas leituras artísticas e literárias começam a repensar as identidades nacionais na América Latina e, em maneira transversal, nasce uma crítica à importação de conceitos europeus de civilidade. Este processo de mudança pode ser observado em profundidade na obra de Gabriela Mistral que mostra, na sua escritura, essa transformação continental, através da análise do mar Mediterrâneo, que vive uma passagem de um espaço de latinidade a outro, de mestiçagem. Nos textos de Mistral, percebe-se uma duplicidade de cruzamentos analíticos entre as relações Norte e Sul, quando a autora fala dos contrastes europeus, fala, também, daqueles do continente americano. Neste contexto, o velho mundo, ou a parte mais meridional do mesmo, empresta sua experiência histórica para justificar a positividade do novo homem latinoamericano: multiétnico

    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

    Since the beginning of the VLT operations in 1998, substantial effort has been put in the development of automatic data reduction tools for the VLT instruments. A VLT instrument pipeline is a complex system that has to be able to identify and classify each produced FITS file, optionally retrieve calibration files from a database, use an image processing software to reduce the data, compute and log quality control parameters, produce FITS images or tables with the correct headers, optionally display them in the control room and send them to the archive. Each instrument has its own dedicated pipeline, based on a common infrastructure and installed with the VLT Data Flow System (DFS). With the increase in the number and the complexity of supported instruments and in the rate of produced data, these pipelines are becoming vital for both the VLT operations and the users, and request more and more resources for development and maintenance. This paper describes the different pipeline tasks with some real examples. It also explains how the development process has been improved to both decrease its cost and increase the pipelines quality using the lessons learned from the first instruments pipelines development.

    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.

    2008-01-01

    An improved self-validating thermocouple (SVT) instrumentation system not only acquires readings from a thermocouple but is also capable of detecting deterioration and a variety of discrete faults in the thermocouple and its lead wires. Prime examples of detectable discrete faults and deterioration include open- and short-circuit conditions and debonding of the thermocouple junction from the object, the temperature of which one seeks to measure. Debonding is the most common cause of errors in thermocouple measurements, but most prior SVT instrumentation systems have not been capable of detecting debonding. The improved SVT instrumentation system includes power circuitry, a cold-junction compensator, signal-conditioning circuitry, pulse-width-modulation (PWM) thermocouple-excitation circuitry, an analog-to-digital converter (ADC), a digital data processor, and a universal serial bus (USB) interface. The system can operate in any of the following three modes: temperature measurement, thermocouple validation, and bonding/debonding detection. The software running in the processor includes components that implement statistical algorithms to evaluate the state of the thermocouple and the instrumentation system. When the power is first turned on, the user can elect to start a diagnosis/ monitoring sequence, in which the PWM is used to estimate the characteristic times corresponding to the correct configuration. The user also has the option of using previous diagnostic values, which are stored in an electrically erasable, programmable read-only memory so that they are available every time the power is turned on.

    1. Three different quaternary ammonium compound solutions remained bactericidal against specific vegetative bacteria in three orthodontic offices over a ten day working period. However, no spore formers or viruses were tested. 2. Bacterial contaminants were cultured on pliers and scalers at the chair at least once in each of three orthodontic offices sampled twice a day for ten working days. 3. Sampled chairside instruments wiped with an alcohol sponge only, between patients, were contaminated an excessive 32.5% of the time, too frequently to be seriously considered for routine disinfection of pliers. 4. Chairside instruments, sampled regardless of other means of disinfection or sterilization used, were contaminated from 3.5 to 15% of the time. Therefore, storage and handling of orthodontic instruments must be evaluated and upgraded to prevent recontamination of previously sterilized instruments. 5. Staff personnel need courses in sterilization and disinfection procedures to prevent cross contamination from patient to patient and to protect themselves. These courses should be related specifically to orthodontic practice procedures.

    Full Text Available Este artigo tem como objetivo problematizar a pertinência de uma política de saúde para a população de Gays, Lésbicas, Bissexuais, Travestis e Transexuais - GLBT. 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.

    1975-01-01

    The current "Energy Crisis" has dramatically increased our potential need for coal, the worlds most abundant fossil fuel. This will probably lead to a greater use of automation and instrumentation in the coal mining industry. The presence of methane in coal mines and in the coal itself plus the presence of coal dust, both of which can form an explosive atmosphere in air, means that the possibility of a gas or coal dust ignition must be considered when designing, purchasing and installing new equipment in this industry. In addition, many metallurgical processes involve the use of potentially explosive substances against which similar safety precautions must be taken. This paper outlines the various methods of protection currently in use and proposed for electrical instruments in explosive atmospheres, with particular emphasis on the work of the International Electrotechnical Commission.

    Although India has a long experience in ship-borne experiments and oceanographic instrumentation, the atmospheric component has not received much attention in the past. In this paper, the basis of the atmospheric instrumentation system assembled for use on board ORV Sagar Kanya for the BOBMEX- Pilot experiment is described along with some representative results. Wherever possible, Woods Hole's IMET recommendations for meteorological sensors for applications in the marine environment have been followed to keep our measurements in par with international standards. The sensors were tested during the BOBMEX-Pilot experiment and all sensors worked well. Velocity, humidity and temperature data have been successfully collected using fast sensors. It is shown that the component due to the ship's pitching motion can be removed from the measured vertical velocity by making use of an accelerometer. This makes it possible to calculate the surface fluxes by direct methods.

  14. High resolution tomographic instrument development

    Energy Technology Data Exchange (ETDEWEB)

    1992-08-01

    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.

    The APEX-SZ instrument is a millimeter-wave cryogenic receiver designed to observe galaxy clusters via the Sunyaev-Zel'dovich effect from the 12 m APEX telescope on the Atacama plateau in Chile. The receiver contains a focal plane of 280 superconducting transition-edge sensor (TES) bolometers instrumented with a frequency-domain multiplexed readout system. The bolometers are cooled to 280 mK via a three-stage helium sorption refrigerator and a mechanical pulse-tube cooler. Three warm mirrors, two 4 K lenses, and a horn array couple the TES bolometers to the telescope. APEX-SZ observes in a single frequency band at 150 GHz with 1' angular resolution and a 22' field-of-view, all well suited for cluster mapping. The APEX-SZ receiver has played a key role in the introduction of several new technologies including TES bolometers, the frequency-domain multiplexed readout, and the use of a pulse-tube cooler with bolometers. As a result of these new technologies, the instrument has a higher instantaneous sensitivity a...

Corporate reputation itself has been identified as one of the key intangible assets which create the company’s added value. Understanding of the importance of corporate reputation has been determined as a significant component of the company’s competitiveness, that is, of its competitive edge. Reputation is a normal part of our life and an integral part of our society. Our interest in the honesty and integrity of others is firmly established in all cultures and nowadays the focus of this interest is switching increasingly on companies. Corporate reputation can be acquired by means of strong, well-developed strategies, which are crucial for the opinion of stakeholders regarding future stability and competitive sustainability of the company. On the other hand, it should be emphasized that in order to manage it, corporate reputation has to be measured first. However, although the concept of corporate reputation is universally accepted and its significance has been recognized especially in the last two decades, the process of its measurement is still at an early stage and there is no universally accepted instrument for its measurement. Therefore, the author of this paper gives an overview of the instruments used for the measurement of corporate reputation which have gained a foothold through former practical usage.

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.

    The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the Universe using the Baryon Acoustic Oscillation technique. The spectra of 40 million galaxies over 14,000 sq deg will be measured during the life of the experiment. A new prime focus corrector for the KPNO Mayall telescope will deliver light to 5,000 fiber optic positioners. The fibers in turn feed ten broad-band spectrographs. We present the design details of the instrument mechanism control systems for the spectrographs. Each spectrograph has a stand-alone mechanism control box that operates the unit's four remotely-operated mechanisms (two shutters and two Hartmannn doors), and provides a suite of temperature and humidity sensors. Each control box is highly modular, and is operated by a dedicated on-board Linux computer to provide all of the control and monitoring functions. We describe our solution for integrating a number of network-connected devices within each unit spectrograph, and describe the basic software architecture.

  4. Instrumentation for mass spectrometry: 1997

    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.

    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}.

    This paper provides a historical review of the evolution of the technologies that led to modern microcomputer-based medical instrumentation. I review the history of the microprocessor-based system because of the importance of the microprocessor in the design of modern medical instruments. I then give some examples of medical instruments in which the microprocessor has played a key role and in some cases has even empowered us to develop new instruments that were not possible before. I include a discussion of the role of the microprocessor-based personal computer in development of medical instruments.

    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.

    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.

    Resumo: Este artigo apresenta uma nova abordagem para a resolução do Problema de Programação de Tripulações no Sistema de Transporte Público (PPT. O modelo se baseia na metaheurística GRASP cuja busca local é realizada pelo método da Busca em Vizinhança de Grande Porte, conhecida na literatura como Very Large-Scale Neighborhood Search. O grande diferencial da aplicação desta técnica de busca para o PPT é que, além de incorporar os movimentos de realocação e troca de tarefas, realizados tradicionalmente, ela também permite considerar trocas do tipo 3-optimal, 4-optimal, até o limite de n-optimal, para uma solução com n tripulações. A implementação da heurística proposta foi testada com dados de problemas reais de uma empresa que opera em Belo Horizonte, e os resultados foram comparados com as soluções adotadas pela empresa. Desta forma foi possível observar que o modelo apresentado neste trabalho produziu soluções mais econômicas do que aquelas praticadas pela empresa.

    Abstract: This paper presents a new approach to solve the Crew Scheduling Problem (CSP for public mass transport system. The proposed model is based on the GRASP metaheuristic framework, where the local search is performed by the Very Large-Scale Neighborhood (VLSN search technique. The great differential of this search technique applied to the CSP is that, in addition to task reassigning and swapping movements, adopted in previous work, it also allows considering 3-optimal, 4-optimal, up to n-optimal task movements, for a solution with n crews, yielding to improved solutions. The proposed heuristic was tested with data from real problems of a bus company operating in the city of Belo Horizonte, and the results compared to the manual solution adopted by the company. Thus it was observed that the model presented in this work have produced more economical solutions than those used by the company.

    The purpose of this article is to discuss the different types of instruments of innovation policy, to examine how governments and public agencies in different countries and different times have used these instruments differently, to explore the political nature of instrument choice and design (and...... associated issues), and to elaborate a set of criteria for the selection and design of the instruments in relation to the formulation of innovation policy. The article argues that innovation policy instruments must be designed and combined into mixes in ways that address the problems of the innovation system....... These mixes are often called “policy mix”. The problem-oriented nature of the design of instrument mixes is what makes innovation policy instruments ‘systemic’....

    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.

    2008-01-01

    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.

    2012-01-01

    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.

    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.

    Full Text Available We present a mobile instrumentation toolkit, AWARE, an open-source effort to develop an extensible and reusable platform for capturing, inferring, and generating context on mobile devices. Mobile phones are sensor-rich but resource-constrained, and therefore several considerations need to be addressed when creating a research tool that ensures problem-free context collection. We demonstrate how AWARE can mitigate researchers’ effort when building mobile data-logging tools and context-aware applications, with minimal battery impact. By encapsulating implementation details of sensor data retrieval and exposing the sensed context as higher-level abstractions, AWARE shifts the focus from software development to data analysis, both quantitative and qualitative. We have evaluated AWARE in several case studies and discuss its use, power consumption, and scalability.

    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.

  4. Care and sterilization of endourologic instruments.

    1988-08-01

    All endourologic instruments must be handled properly if they are to continue to function properly. Care must be taken in washing and sterilizing of this equipment, as not all endoscopic equipment can endure all methods, and people who are working with these instruments must be taught the proper care and sterilization methods of each. For example, fiberoptic telescopes and light cables must never be autoclaved; ethylene oxide is the method of choice. Disinfectant is an alternative. Loops, sheaths, high-frequency cables, resectoscopes, and working elements should be sterilized by ethylene oxide. Loops and high-frequency cables should not be soaked in a disinfectant, but other instruments may be soaked. All instruments should be dried before sterilization. Too much emphasis cannot be placed on the importance of proper storage of these very fragile fiberoptic instruments. With proper care and sterilization, these instruments will need fewer repairs and function properly for a longer time.

    On the ground of an analysis into properties of titanium and its alloys the fields of their possible utilization for making various medical instruments are proposed. Because of their insufficient hardness and wear-resistance the titanium alloys cannot be recommended for making medical instruments with thin cutting edges. For the reasons of their insufficient strength, low wear-resistance and substandard modulus of elasticity, it is inexpedient to use titanium alloys in making many types of clamping medical instruments. Nor is it advisable to employ titanium alloys in handles of the instruments, for this may lead to a contact corrosion of their working parts. The use of titanium alloys is recommended for making bone-joining members, retracting medical instruments, of the spatula and speculum types, some kinds of non-magnetic pincers and ultrasonic medical instruments.

O objetivo deste estudo foi demonstrar a sensibilidade no diagnóstico da desnutrição protéico-calórica realizado pelas equipes de Saúde da Família, quando são utilizados apenas dados primários como instrumentos de busca da adequação e posterior informação destes, via SIAB, e por meio da busca ativa de crianças de 0 a 23 meses e 29 dias e obtenção de seus dados antropométricos delas. Trata-se de estudo seccional, realizado no município de Patos de Minas (MG, de janeiro a abril de 2005. As prevalências de desnutrição protéico-calórica informadas no SIAB foram 2,35% e 2,5%, nas equipes A e B, respectivamente. As prevalências de desnutrição encontradas a partir da busca ativa, dos dados antropométricos e do cálculo dos índices peso-idade foram 14,12% e 13,75% nas equipes A e B, respectivamente. Essas foram superiores à prevalência descrita pela Pesquisa Nacional de Demografia e Saúde, cuja prevalência foi 5,7%. As prevalências de desnutrição protéico-calórica com base no índice peso-idade, mediante exclusivamente a utilização do SIAB como fonte de dados, levam ao subdiagnóstico do problema.

    In this paper we describe the main characteristics of the JEM-EUSO instrument. The Extreme Universe Space Observatory on the Japanese Experiment Module (JEM-EUSO) of the International Space Station (ISS) will observe Ultra High-Energy Cosmic Rays (UHECR) from space. It will detect UV-light of Extensive Air Showers (EAS) produced by UHECRs traversing the Earth's atmosphere. For each event, the detector will determine the energy, arrival direction and the type of the primary particle. The advantage of a space-borne detector resides in the large field of view, using a target volume of about 1012 tons of atmosphere, far greater than what is achievable from ground. Another advantage is a nearly uniform sampling of the whole celestial sphere. The corresponding increase in statistics will help to clarify the origin and sources of UHECRs and characterize the environment traversed during their production and propagation. JEM-EUSO is a 1.1 ton refractor telescope using an optics of 2.5 m diameter Fresnel lenses to focus the UV-light from EAS on a focal surface composed of about 5,000 multi-anode photomultipliers, for a total of ≃3ṡ105 channels. A multi-layer parallel architecture handles front-end acquisition, selecting and storing valid triggers. Each processing level filters the events with increasingly complex algorithms using FPGAs and DSPs to reject spurious events and reduce the data rate to a value compatible with downlink constraints.

  11. Development of autonomous triggering instrumentation

    Watkins, Steve E.; Swift, Theresa M.; Fonda, James W.

    2008-03-01

    Triggering instrumentation for autonomous monitoring of load-induced strain is described for economical, fast bridge inspection. The development addresses one aspect for the management of transportation infrastructure - bridge monitoring and inspection. The objectives are to provide quantitative performance information from a load test, to minimize the setup time at the bridge, and to minimize the closure time to traffic. Multiple or networked measurements can be made for a prescribed loading sequence. The proposed smart system consists of in-situ strain sensors, an embedded data acquisition module, and a measurement triggering system. A companion control unit is mounted on the truck serving as the load. As the truck moves to the proper position, the desired measurement is automatically relayed back to the control unit. In this work, the testing protocol is developed and the performance parameters for the triggering and data acquisition are measured. The test system uses a dedicated wireless sensor mote and an infrared positioning system. The electronic procedure offers improvements in available information and economics.

    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.

    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{sup -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. (orig.)

    Pickup elements for string instruments, in particular for electric guitars, represent a new application area for magnetoresistive sensors. Recently we developed a sensor configuration with permanent magnets for this purpose. For the first experiments we used commercial anisotropic magnetoresistance sensors (Philips KMZ10) mounted on small ferrite bias magnets. Recently we equipped an electric guitar with prototypes comprising giant magnetoresistance (GMR) sensors. These prototype MR pickup elements showed several clear advantages compared to the presently commonly used inductive pickup units. They are much less sensitive to disturbing electromagnetic fields (>1000×at 5 kHz), mainly because their active sensor area is several orders of magnitude smaller (a few mm2 instead of cm2). Also the larger freedom in the choice of the permanent magnets (due to the larger sensitivity of the GMR elements) is advantageous: employing smaller magnets reduces the damping and thus significantly improves the sustain, the magnets can be less expensive and more stable magnet materials can be chosen so that aging effects are eliminated.

    Nagai, T; Sleege, G; Petry, D

    2007-01-01

    VERITAS is a new atmospheric Cherenkov imaging telescope array to detect very high energy gamma rays above 100 GeV. The array is located in southern Arizona, USA, at an altitude of 1268m above sea level. The array consists of four 12-m telescopes of Davies-Cotton design and structurally resembling the Whipple 10-m telescope. The four focal plane instruments are equipped with high-resolution (499 pixels) fast photo-multiplier-tube (PMT) cameras covering a 3.5 degree field of view with 0.15 degree pixel separation. Light concentrators reduce the dead-space between PMTs to 25% and shield the PMTs from ambient light. The PMTs are connected to high-speed preamplifiers allowing operation at modest anode current and giving good single photoelectron peaks in situ. Electronics in the focus box provides real-time monitoring of the anode currents for each pixel and ambient environmental conditions. A charge injection subsystem installed in the focus box allows daytime testing of the trigger and data acquisition system b...

    Many atmospheric and climatic criteria have to be taken into account for the selection of a suitable site for the next generation of imaging air-shower Cherenkov telescopes, the "Cherenkov Telescope Array" CTA. Such data are not available with sufficient precision or the comparability to allow for a comprehensive characterization of the proposed sites to be made. Identical cross-calibrated instruments have been developed which allow for precise comparison between sites, the cross-validation of existing data, and the ground-validation of satellite data. The site characterization work package of the CTA consortium opted to construct and deploy 9 copies of an autonomous multi-purpose weather sensor, incorporating an infrared cloud sensor a newly developed sensor for measuring the light of the night sky, and an All-Sky-Camera, the whole referred to as Autonomous Tool for Measuring Observatory Site COnditions PrEcisely (ATMOSCOPE).

  19. Instruments for subsurface monitoring of geothermal subsidence

    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.

  20. Policy Instruments towards a Sustainable Waste Management

    2013-02-01

    Full Text Available The aim of this paper is to suggest and discuss policy instruments that could lead towards a more sustainable waste management. The paper is based on evaluations from a large scale multi-disciplinary Swedish research program. The evaluations focus on environmental and economic impacts as well as social acceptance. The focus is on the Swedish waste management system but the results should be relevant also for other countries. Through the assessments and lessons learned during the research program we conclude that several policy instruments can be effective and possible to implement. Particularly, we put forward the following policy instruments: “Information”; “Compulsory recycling of recyclable materials”; “Weight-based waste fee in combination with information and developed recycling systems”; “Mandatory labeling of products containing hazardous chemicals”, “Advertisements on request only and other waste minimization measures”; and “Differentiated VAT and subsidies for some services”. Compulsory recycling of recyclable materials is the policy instrument that has the largest potential for decreasing the environmental impacts with the configurations studied here. The effects of the other policy instruments studied may be more limited and they typically need to be implemented in combination in order to have more significant impacts. Furthermore, policy makers need to take into account market and international aspects when implementing new instruments. In the more long term perspective, the above set of policy instruments may also need to be complemented with more transformational policy instruments that can significantly decrease the generation of waste.

  12. Intonation and Compensation of Fretted String Instruments

    CERN Document Server

    Varieschi, Gabriele U

    2009-01-01

    In this paper we present mathematical models and we analyze the physics related to the problem of intonation of musical instruments such as guitars, mandolins and similar, i.e., we study how to produce perfectly in tune notes on these instruments. This analysis begins with the correct fret placement on the instrument fingerboard, following precise mathematical laws, but then it becomes increasingly complicated due to the geometrical deformation of the strings when these instruments are played, and also due to the inharmonic characteristics of the same strings. As a consequence of these factors, perfect intonation of all the notes on the instrument can never be achieved, but complex compensation procedures are introduced and studied to minimize the problem. To test the validity of these compensation procedures, we have performed extensive measurements using standard monochord sonometers and other basic acoustical devices, which confirm the correctness of our theoretical models. In particular, these experimenta...

    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.

    Full Text Available A capacidade de processar simultaneamente vários estágios cognitivos ainda é motivo de discordância entre os modelos que tentam compreender o processamento da informação visual. Muitos resultados experimentais apontam basicamente duas maneiras possíveis de fluxo da informação entre estágios de processamento: uma discreta e outra contínua. No presente estudo, dois experimentos foram delineados para investigar se a informação inicialmente descartada, em um estágio pré-atentivo, pode influenciar o processamento atentivo da informação selecionada em uma tarefa de busca visual. De maneira geral, os resultados observados nestes experimentos mostram que os estímulos inicialmente descartados em um processo automático de seleção não interferem no processamento atentivo dos estímulos na tarefa de busca visual. Este resultado apóia os modelos que predizem uma seleção precoce dos elementos relevantes para o processamento atentivo e uma transmissão discreta da informação entre os estágios cognitivos de processamento.The capacity of processing several cognitive stages simultaneously still generates a considerable disagreement among models that try to understand the processing of visual information. Many experimental results suggest two main possibilities for the information flow between information processing stages: a discrete or a continuous flow. Two experiments have in the present study to investigate were designed attentional processing whether the information at first discarded in a pre-attentive state can influence the of selected information in a visual search task. The results show that the stimuli initially discarded in an automatic process of selection do not interfere in the attention all processing of stimuli in a visual search. The results support the models that predict an early selection of the relevant stimuli and a discrete transmission of the information between the cognitive processing stages.

    2013-01-01

    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

    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...

  20. Aquarius Instrument and Salinity Retrieval

    Le Vine, D. M.

    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

  1. Overview of intercalibration of satellite instruments

    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

    2010-01-01

    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.

    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.

    Continuous quality improvement (CQI) activities depend on valid and reliable instruments to generate data. An evaluation of internal and external customer satisfaction is one of the pillars of the CQI process. This article describes the development of a valid and reliable instrument for measuring physicians' satisfaction with the orthopedic nursing units at a major medical trauma center. The physician satisfaction survey instrument was found to be internally consistent (alpha = .95). Confirmatory factor analysis revealed that 68% of the variance in physician satisfaction scores (eigenvalue = 8.14) was explained by using a single-factor model.

    1997-06-01

    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.

  11. Cryogenic Detectors (Narrow Field Instruments)

    Science.gov (United States)

    Hoevers, H.; Verhoeve, P.

    Two cryogenic imaging spectrometer arrays are currently considered as focal plane instruments for XEUS. The narrow field imager 1 (NFI 1) will cover the energy range from 0.05 to 3 keV with an energy resolution of 2 eV, or better, at 500 eV. A second narrow field imager (NFI 2) covers the energy range from 1 to 15 keV with an energy resolution of 2 eV (at 1 keV) and 5 eV (at 7 keV), creating some overlap with part of the NFI 1 energy window. Both narrow field imagers have a 0.5 arcmin field of view. Their imaging capabilities are matched to the XEUS optics of 2 to 5 arcsec leading to 1 arcsec pixels. The detector arrays will be cooled by a closed cycle system comprising a mechanical cooler with a base temperature of 2.5 K and either a low temperature 3He sorption pump providing the very low temperature stage and/or an Adiabatic Demagnetization Refrigerator (ADR). The ADR cooler is explicitly needed to cool the NFI 2 array. The narrow field imager 1} Currently a 48 times 48 element array of superconducting tunnel junctions (STJ) is envisaged. Its operating temperature is in the range between 30 and 350 mK. Small, single Ta STJs (20-50 mum on a side) have shown 3.5 eV (FWHM) resolution at E = 525 eV and small arrays have been successfully demonstrated (6 times 6 pixels), or are currently tested (10 times 12 pixels). Alternatively, a prototype Distributed Read-Out Imaging Device (DROID), consisting of a linear superconducting Ta absorber of 20 times 100 mum2, including a 20 times 20 mum STJ for readout at either end, has shown a measured energy resolution of 2.4 eV (FWHM) at E = 500 eV. Simulations involving the diffusion properties as well as loss and tunnel rates have shown that the performance can be further improved by slight modifications in the geometry, and that the size of the DROIDS can be increased to 0.5-1.0 mm without loss in energy resolution. The relatively large areas and good energy resolution compared to single STJs make DROIDS good candidates for the

  13. Thermal vacuum chamber repressurization with instrument purging

    Woronowicz, Michael S.

    2016-09-01

    At the conclusion of cryogenic vacuum testing of the James Webb Space Telescope Optical Telescope Element Integrated Science Instrument Module (JWST-OTIS) in NASA Johnson Space Center's (JSCs) thermal vacuum (TV) Chamber A, contamination control (CC) engineers are postulating that chamber particulate material stirred up by the repressurization process may be kept from falling into the Integrated Science Instrument Module (ISIM) interior to some degree by activating instrument purge flows over some initial period before opening the chamber valves. This manuscript describes development of a series of models designed to describe this process. The models are strung together in tandem with a fictitious set of conditions 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.

  14. Splinting for adaptation of musical instruments.

    Science.gov (United States)

    Boyette, Jennifer

    2005-01-01

    Classic instrument design does not always match the physical capacity of the musician, as instruments are often chosen because of the pleasing sound and not the ease of play. Devices that are commercially available to create a more ergonomic structure may not address the specific needs of a musician with a chronic condition. Through basic splinting of the musician with an injury, these physical stressors can be reduced, allowing the continuation of musical practice and performance. Appropriate design modification requires a solid understanding of upper extremity anatomy, splint design technique, and the biomechanic principles of playing the instrument. Through knowledge of music theory and appreciation, one may modify the instrument while protecting tonal flexibility, resonance, mechanical freedom, and sound quality. Two case studies present a range of splint design, from small to large, static to dynamic, and for congenital or chronic conditions.

  16. Instrumenting Beliefs in Threshold Public Goods.

    de Oliveira, Angela C M; Spraggon, John M; Denny, Matthew J

    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.

    2009-01-01

    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 ...

    Virtual instruments based on Monte-Carlo techniques are now integral part of novel instrumentation development and the existing codes (McSTAS and Vitess) are extensively used to define and optimise novel instrumental concepts. Neutron spectrometers, however, involve a large number of parameters and their optimisation is often a complex and tedious procedure. Artificial intelligence algorithms are proving increasingly useful in such situations. Here, we present an automatic, reliable and scalable numerical optimisation concept based on the canonical genetic algorithm (GA). The algorithm was used to optimise the 3D magnetic field profile of the NSE spectrometer SPAN, at the HMI. We discuss the potential of the GA which combined with the existing Monte-Carlo codes (Vitess, McSTAS, etc.) leads to a very powerful tool for automated global optimisation of a general neutron scattering instrument, avoiding local optimum configurations.

    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).

    Full Text Available The objective was to validate the content of an instrument on nasogastric intubation skills based on Pasquali's model of content validation. This was a methodological study conducted with 23 nursing teachers in public higher education institutions in Rio Grande do Norte. The Content Validation Index (CVI and Kappa Index was applied. In the overall evaluation, the instrument obtained a CVI with values above 0.75 with a total CVI of 0.95 and a total Kappa of 0.91. However, some changes were made on the instructional sequence requirements of the topics, and to vocabulary. The instrument proved to be reliable and trustworthy in facilitating nursing care quality and can be used for health services and educational institutions to assess skill levels of professionals and undergraduate students. However, the instrument requires additional stages for a more precise and specific content validation.

  11. The SINQ instrument control software system

    Science.gov (United States)

    Heer, H.; Könnecke, M.; Maden, D.

    The spallation neutron source SINQ at Villigen, Switzerland, is a continuous source with a flux of about 10 14 n/s cm 2. 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.

    Full Text Available Objective: This study was designed to evaluate the efficiency of microwave sterilization of orthodontic instruments and molar bands immersed in plain distilled water with and without oral rinse, and to ascertain the minimum time of exposure required to sterilize. Materials and Methods: The orthodontic instruments (hinged and nonhinged, molar bands and mouth mirrors used in the patient′s mouth were selected for the study. The instruments were divided into two groups - Group I with oral rinse-set A (0.01% chlorhexidine gluconate and set B (0.025% betadine and Group II (included sets C and D without oral rinse. The instruments of set A, B and C were microwaved at 2,450 MHz, 800 W for 5 min, whereas, set D was microwaved for 10 min at the same above mentioned specifications. The efficacy of sterilization was assessed by stab inoculation of the instruments onto trypticase soya agar plates. The plates were checked for bacterial growth following incubation at 37°C for 24 h. For sterility control, Geobacillus stearothermophilus (MTCC 1518 was included. Results: No growth was observed in the plates that were inoculated with the microwaved orthodontic instruments of sets A, B and D, whereas scanty bacterial growth was observed in the plates inoculated with the microwaved set C instruments. Conclusion: Effective sterilization was achieved when the orthodontic instruments and molar bands were immersed in distilled water without oral rinse and microwaved for 10 min as also for those that were immersed in distilled water with oral rinse and microwaved for 5 min.

    Many applications today require the Fourier-transform (FT) spectrometer to perform close to its limitations, such as taking many quantitative measurements in the visible and in the near infrared wavelength regions. In such cases, the instrument should not be considered as a perfect ""black box."" Knowing where the limitations of performance arise and which components must be improved are crucial to obtaining repeatable and accurate results. One of the objectives of this book is to help the user identify the instrument's bottleneck.

  7. Surgical instrument similarity metrics and tray analysis for multi-sensor instrument identification

    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.

  18. Influence of musical instruments on tooth positions.

    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.

    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.

  20. Increased Science Instrumentation Funding Strengthens Mars Program

    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.

  1. Survivorship analysis of pedicle spinal instrumentation.

    McAfee, P C; Weiland, D J; Carlow, J J

    1991-08-01

    Between 1985 and 1989, the senior author performed 120 consecutive pedicle instrumentation cases--78 Steffee (VSP) procedures and 42 procedures using Cotrel-Dubousset instrumentation. Posterolateral or posterior fusions using autogenous iliac bone graft were performed across the instrumented vertebrae in all cases. Survivorship analysis was used to calculate a predicted cumulative rate of success for this series of patients over 10 years postoperative follow-up. The criteria of failure of pedicular instrumentation or "death" of an implant were defined as 1) screw bending, 2) screw breakage, 3) infection, 4) loosening of implants, 5) any rod or plate hardware problems, or 6) removal of hardware due to a neurologic complication. Out of 526 pedicle screws (175 Cotrel-Dubousset screws, 351 VSP screws) there were 22 problem screws (22/526 = 4.18%). Six screws had bent, none were infected, 16 screws had broken, and none were loose. The 22 problem screw events occurred in 12 patients. In seven patients, the instrumentation failure was an incidental radiographic finding, in that patients had a solid posterolateral fusion. The remaining five patients had screw breakage in association with a pseudarthrosis. Life table calculations predicted the survivorship of instrumentation without complications would be 80% at 10 years postoperative follow-up. Actuarial analysis predicted the survivorship of solid posterolateral fusion at 90% at 10 years follow-up. This survivorship rate is similar to those predicted at 10 years follow-up for other more widely used orthopedic surgical implants such as total hip arthroplasty components.

    2000-01-01

    Full Text Available The article describes some new ways in which the Brazilian middle classes fit socially into the "world of neoliberalism". In recent years these layers of society have been prompted to believe that the traditional civil service job or, more recently, careers with large companies are no longer possible or desirable. These former pretensions have been replaced by the idea that franchising is the thing of the future. On the other side, the notion of "employability" has gained ground: through carefully thought-out career management and the accumulation of knowledge and skills, the agent can become "economically viable". In cognitive terms, the latter trend is the opposite of the former and gains stability through its negation. In analyzing the evidence, the author focuses on the historical antecedents and symbolic operations that work to lend the situation coherence. He also endeavors to identify connections with the economic sphere.

    Background Wound infection following spinal instrumented surgery is a frequent complication.The optimal treatment of acute deep wound infection following spinal instrumentation fusion remains controversial because of variability in cohort identification,definition of an infection,and the instrument used to measure outcomes.This retrospective study evaluated the clinical curative effect for postoperative spinal infection after instrumented spine fusion with extensive debridement,or implant removal.Methods From January 2004 to October 2009,851 patients were identified who underwent surgical treatment of spinal diseases.The medical records of patients who developed infections were reviewed in detail.Results Of 851 patients,41 (4.9%) developed an infection.Thirty-three were acute,and eight were delayed.Acute infected cases were managed with antibiotic therapy,and aggressive debridement of the wound and soft tissues leaving all instrumentation in situ in all but one patient.The most common symptoms of acute infection included:posterior incisional drainage (26 of 33 patients),back pain (22 of 33 patients) and fever (13 of 33 patients).Among patients with delayed onset infection,five of eight patients had local pain,four of eight patients had incision drainage,and one patient had a prolonged period of intermittent fever.The most frequent causative organism for postoperative spinal infection following spine surgery is Staphylococcus aureus.Pseudarthrosis was noted in long-term follow-up in four of 41 patients.Conclusions We recommend irrigation and debridement,no instrumentation removal,and,if necessary,repeat debridement followed by delayed primary closure for the treatment of acute deep infection with instrumentation.

    2010-03-01

    Full Text Available Parece existir um consenso na comunidade contábil de que leis e normas de alta qualidade resultam na melhora da confiança dos usuários das demonstrações contábeis, o que é fundamental para o desenvolvimento dos mercados e, consequentemente, para a alocação de recursos na economia. Mas, até que ponto uma norma ou lei deve exigir a divulgação de informações aos usuários? Quais critérios devem ser levados em conta pelos órgãos normatizadores? A resposta para essas questões passam, fundamentalmente, pelo entendimento da relação entre o direito e a contabilidade. Isso ocorre, porque a contabilidade é, também, alvo de regulação. Contudo, diferentemente do que acontece na economia, a regulação é, todavia, pouca estudada na área contábil. Dentro desse contexto, o presente trabalho busca discutir questões relacionadas à regulação contábil e está organizado em três seções: (i primeiramente, discute-se a discricionariedade inerente à prática contábil, que gera o chamado “gerenciamento de resultados ou lucros”; (ii em seguida, busca-se compreender quaisseriam as justificativas e os objetivos da regulação contábil; (iii por último, discute-se o processo de convergência da contabilidade brasileira, com a migração para as normas internacionais e seus respectivos impactos.There seems to be a consensus among the accounting community that high quality accounting standards improve the level of confidence of financial statements users, which is essential for financial markets’ development, and consequently, for resources’ distribution economy. However, to what extend should regulators require the users to provide information disclosure? Which criteria should be taken into consideration by the regulating institutions? The answer to these questions relies mainly on the understanding of the relation between accounting and law. That occurs because accounting is also regulated by laws. On the other hand

    2013-03-01

    Full Text Available Introduction and Objective: The aim of this study was to review the literature on the systems used to decontaminate the implant’s surface. Different instruments have been proposed, but there is no agreement in the literature about which methods would be more efficient with no damage to the implant surface. It was reported the use of plastic, carbon fiber, stainless-steel and titanium curettes and also the use of other systems such as ultrasonic points with different tips, rubber cups and air abrasion. Literature review: In most of the studies, the injury caused on the titanium surface at the time of instrumentation was examined. In others, the cell adhesion on the titanium dental implants following instrumentation of the implant surface was observed. Moreover, to enhance cleaning around implants, ultrasonic systems were recently tested. Conclusion: Metal instruments can lead to major damage to implant surface, therefore, they are not indicated for decontamination of dental implants surfaces. Furthermore, non-metallic instruments, such as plastic curettes, rubber cups, air abrasion and some ultrasonic systems seem to be better choices to remove calculus and plaque of the sub- and supra-gingival peri-implant area. It is noteworthy that more studies evaluating the effects of these systems are required to establish best practices to be used in the treatment of patients with dental implants.

    2000-01-01

    A new financial instrument (a new kind of a loan) is introduced. The loan-stock instrument (LSI) combines fixed rate instruments (loans, etc.) with other financial instruments that have higher volatilities and returns (stocks, mutual funds, currencies, derivatives, options, etc.). This new loan depends on the value of underlying security (for example, stock) in such a way that when underlying security increases, the value of loan decreases and backwards. The procedure to create a risk free portfolio and a technique to fairly price the LSI is described. The philosophy behind this procedure is quite similar to the Black-Scholes formalism in option theory. Creation of the risk free portfolio is possible because the change in the underlying security offsets the change in the value of the loan (or the amount that the borrower has to repay). The new financial instrument takes an advantage of the fact that on average the stock market grows in time. It is beneficial for both the borrower and the lender. The LSI is mo...

    1.1 This practice defines the basic steps of Instrumented Indentation Testing (IIT) and establishes the requirements, accuracies, and capabilities needed by an instrument to successfully perform the test and produce the data that can be used for the determination of indentation hardness and other material characteristics. IIT is a mechanical test that measures the response of a material to the imposed stress and strain of a shaped indenter by forcing the indenter into a material and monitoring the force on, and displacement of, the indenter as a function of time during the full loading-unloading test cycle. 1.2 The operational features of an IIT instrument, as well as requirements for Instrument Verification Annex A1), Standardized Reference Blocks (Annex A2) and Indenter Requirements (Annex A3) are defined. This practice is not intended to be a complete purchase specification for an IIT instrument. 1.3 With the exception of the non-mandatory Appendix X4, this practice does not define the analysis necessary...

    2004-10-01

    The Neutron Instrument Simulation Package (NISP) performs complete source-to-detector simulations of neutron instruments, including neutrons that do not follow the expected path. The original user interface (MC_Web) is a web-based application, http://strider.lansce.lanl.gov/NISP/Welcome.html. This report describes in detail the newer stand-alone Windows version, NISP_Win. Instruments are assembled from menu-selected elements, including neutron sources, collimation and transport elements, samples, analyzers, and detectors. Magnetic field regions may also be specified for the propagation of polarized neutrons including spin precession. Either interface writes a geometry file that is used as input to the Monte Carlo engine (MC_Run) in the user's computer. Both the interface and the engine rely on a subroutine library, MCLIB. The package is completely open source. New features include capillary optics, temperature dependence of Al and Be, revised source files for ISIS, and visualization of neutron trajectories at run time. Also, a single-crystal sample type has been successfully imported from McStas (with more generalized geometry), demonstrating the capability of including algorithms from other sources, and NISP_Win may render the instrument in a virtual reality file. Results are shown for two instruments under development.

    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.

    Overcoming the complexity of cheese matrix to reliably analyze cheese composition, flavor, and ripening changes has been a challenge. Several sample isolation or fractionation methods, chemical and enzymatic assays, and instrumental methods have been developed over the decades. While some of the methods are well established standard methods, some still need to be researched and improved. This chapter reviews the chemical and instrumental methods available to determine cheese composition and monitor biochemical events (e.g., glycolysis, lipolysis, and proteolysis) during cheese ripening that lead to the formation of cheese flavor. Chemical and enzymatic methods available for analysis of cheese composition (fat, protein, lactose, salt, nitrogen content, moisture, etc.) are presented. Electrophoretic, chromatographic, and spectroscopic techniques are also reviewed in the light of their application to monitor cheese ripening and flavor compounds. Novel instrumental methods based on Fourier-transform infrared spectroscopy that are currently being researched and applied to cheese analysis are introduced.

    Full Text Available A set of features is evaluated for recognition of musical instruments out of monophonic musical signals. Aiming to achieve a compact representation, the adopted features regard only spectral characteristics of sound and are limited in number. On top of these descriptors, various classification methods are implemented and tested. Over a dataset of 1007 tones from 27 musical instruments, support vector machines and quadratic discriminant analysis show comparable results with success rates close to 70% of successful classifications. Canonical discriminant analysis never had momentous results, while nearest neighbours performed on average among the employed classifiers. Strings have been the most misclassified instrument family, while very satisfactory results have been obtained with brass and woodwinds. The most relevant features are demonstrated to be the inharmonicity, the spectral centroid, and the energy contained in the first partial.

    2008-08-01

    Over centuries and millennia, our ancestors worldwide found the most appropriate materials for increasingly complex acoustical applications. In the temperate climate of Europe, where the instruments of the Western symphony orchestra were developed and perfected, instrument makers still primarily take advantage of the unique property combination and the aesthetic appeal of wood. In all other continents, one material dominates and is frequently chosen for the manufacture of wind, string, and percussion instruments: the grass bamboo. Here, we review from a materials science perspective bamboo's and wood's unique and highly optimized structure and properties. Using material property charts plotting acoustic properties such as the speed of sound, the characteristic impedance, the sound radiation coefficient, and the loss coefficient against one another, we analyze and explain why bamboo and specific wood species are ideally suited for the manufacture of xylophone bars and chimes, flutes and organs, violins and zithers, violin bows, and even strings.

    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.

    Common displays such as CRT or LCD screens have limited capabilities in displaying most color spectra correctly. The main disadvantage of these devices is that they work with three primaries and the colors displayed are the mixture of these three colours. Consequently these devices can be confusing in testing human color identification, because the spectral distribution of the colors displayed is the combined spectrum of the three primaries. We have developed a new instrument for spectrally correct color vision measurement. This instrument uses light emitting diodes (LEDs) and is capable of producing all spectra of perceivable colors, thus with appropriate test methods this instrument can be a reliable and useful tool in testing human color vision and in verifying color vision correction.

    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.

    Barbarotto, R; Capitani, E; Laiacona, M

    2001-01-01

    In the literature about category effects in semantic memory, body parts and musical instruments are often considered atypical, because in cases with a disproportionate impairment of living categories body parts are relatively spared, while musical instruments are often severely defective. In this study the performance of 57 subjects affected by diseases generally associated with lexical-semantic impairment, for the most part Alzheimer's disease and other forms of cortical degeneration, but also herpetic encephalitis and traumatic brain damage are analyzed. The subjects were given a picture naming task tapping eight categories: three living categories (animals, fruits and vegetables) and three non-living categories (tools, furniture and vehicles), plus body parts and musical instruments. On a preliminary analysis at the group level, body parts were the least impaired category and musical instruments the most severely impaired, the six living and non-living categories being intermediate. However, these differences disappeared after covariance for lexical frequency, name agreement and age of acquisition. The relationship between living categories, non-living categories, musical instruments and body parts was investigated by means of a Lisrel model of Confirmatory Factor Analysis. Two latent variables related to living and non-living categories respectively were defined, and it was found that both body parts and musical instruments were significantly related only with non-living categories. The results showed that the definition of the latent variable expressing the substrate of non-living categories was less satisfactory than that expressing the living categories. On this basis, the conclusions of this study appear statistically definite but their psychological interpretation is less straightforward.

    A library of Monte Carlo subroutines has been developed for the purpose of design of neutron scattering instruments. Using small-angle scattering as an example, the philosophy and structure of the library are described and the programs are used to compare instruments at continuous wave (CW) and long-pulse spallation source (LPSS) neutron facilities. The Monte Carlo results give a count-rate gain of a factor between 2 and 4 using time-of-flight analysis. This is comparable to scaling arguments based on the ratio of wavelength bandwidth to resolution width.

    Transanal excision of rectal polyps with laparoscopic instrumentation and a single incision laparoscopic port is a novel technique that uses technology originally developed for abdominal procedures from the natural orifice of the rectum. Transanal endoscopic microsurgery (TEM) is a well established surgical approach for certain benign or early malignant lesions of the rectum, under specific indications. Our technique is a hybrid technique of transanal surgery, a reasonable method for polyp resection without the need of the sophisticated and expensive instrumentation of TEM which can be applied whenever endoscopic or conventional transanal surgical removal is not feasible.

    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.

    Downing, Kenneth H

    2013-01-01

    Advances in instrumentation have proceeded at an impressive rate since the invention of the electron microscope. These advances have produced a continuous expansion of the capabilities and range of application of electron microscopy. In order to provide some insights on how continuing advances may enhance cryo-electron microscopy and electron crystallography, we review some of the active areas of instrumentation development. There is strong momentum in areas including detectors, phase contrast devices, and aberration correctors that may have substantial impact on the productivity and expectations of electron crystallographers.

    QUBIC is a unique instrument that crosses the barriers between classical imaging architectures and interferometry taking advantage from both for high sensitivity and systematics mitigation. The scientific target is the detection of the primordial gravitational waves imprint on the Cosmic Microwave Background which are the proof of inflation, holy grail of modern cosmology. In this paper, we show the latest advances in the development of the architecture and the sub-systems of the first module of this instrument to be deployed in Dome Charlie Concordia base - Antarctica in 2015.

    This article introduces a development of pulsed neutron uranium logging instrument. By analyzing the temporal distribution of epithermal neutrons generated from the thermal fission of {sup 235}U, we propose a new method with a uranium-bearing index to calculate the uranium content in the formation. An instrument employing a D-T neutron generator and two epithermal neutron detectors has been developed. The logging response is studied using Monte Carlo simulation and experiments in calibration wells. The simulation and experimental results show that the uranium-bearing index is linearly correlated with the uranium content, and the porosity and thermal neutron lifetime of the formation can be acquired simultaneously.

    The High Efficiency and Resolution Multi Element Spectrograph, HERMES, was an approximately $12 million dollar project to provide a new facility class instrument for the Anglo-Australian Telescope (AAT). It was commissioned in Q4 2013. This paper examines how software challenges presented by HERMES were handled, including: minimizing cost through reusing the existing AAT 2dF/AAOmega facility software as far as possible; using instrument and data simulators to ensure new software was almost ready before any hardware had been seen; extensive upgrading of our fiber data reduction software; dealing with the tighter calibration and alignment tolerances of a high-resolution spectrograph.

The mission scientific drivers correspond to some of the deep questions identified in the Canadian LRP2010, and are also of great interest for the Canadian scientists. Given that there is also a great interest in having an international collaboration in this mission, the Canadian Space Agency awarded two contracts to study a Canadian participation in the mission, one related to each instrument. This paper presents a summary of the technical contributions that were considered for a Canadian contribution to the coronagraph and wide field instruments.

  13. 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.

    2017-01-01

    We have designed and built two spectrographs for use in undergraduate astronomy laboratories at the University of Iowa. The first, a low cost (appx. $500) low resolution (R ~ 150 - 300) grating-prism (grism) spectrometer consists of five optical elements and is easily modified to other telescope optics. The grism spectrometer is designed to be used in a modified filter wheel. This type of spectrometer allows students to undertake projects requiring sensitive spectral measurements, such as determining the redshifts of quasars. The second instrument is a high resolution (R ~ 8000), moderate cost (appx. $5000) fiber fed echelle spectrometer. The echelle spectrometer will allow students to conduct Doppler measurements such as those used to study spectroscopic binaries. Both systems are designed to be used with robotic telescope systems. The availability of 3D printing enables both of these spectrographs to be constructed in hands-on instrumentation courses where students build and commission their own instruments. Additionally, these instruments enable introductory majors and non-majors laboratory students to gain experience conducting their own spectroscopic observations.

    An instrument for measurement of exposure rates between 0.1 and 20 R/h was fabricated. The instrument will be used in connection wtth radiation therapy of gynecologic cancer. A lithium-drifted silicon detector is used. The registered pulse information is treated in the instrument so that the exposure rate may be read directly in R/h. The instrument accumulates pulses during one second, and the repetition time is one second, The error is plus or minus 10% at 0.1 R/h, plus or minus 3% at 1 R/h and less than plus or minus 1% at 10 R/h. The repetition time may be altered to 10 sec. at calibration. This means that it is possible to measure 0.01 R/h with the accuracy 10% and 0.1 R/h with the accuracy 3%. The stability with time and temperature, linearity, energy dependence, direction dependence and lifetime was investigated. (SW

    The Spallation Neutron Source (SNS) vacuum instrumentation and control systems are being designed at Lawrence Berkeley National Laboratory (LBNL), Brookhaven National Laboratory (BNL), Thomas Jefferson National Accelerator facility (TJNAF) and Los Alamos National Laboratory (LANL). Each participating lab is responsible for a different section of the machine: LBNL for the Front-End section, LANL for the warm LINAC section, TJNAF for the cold LINAC section and BNL for the Ring and transfer line sections. The vacuum instrumentation and control systems are scheduled to be installed and be in operation at Oak Ridge National Laboratory in 2004 or 2005. Although the requirements vary for different sections of the machine, a collaborative effort has been made to standardize vacuum instrumentation components and the global control system interfaces. This paper summarizes the design of each sub-section of vacuum instrumentation and control system and discusses SNS standards for Ion Pump and Gauge controllers, Programmable Logic Controller (PLC) interfaces, Ladder Logic programming and the SNS global control system interfaces.

    2009-04-01

    The Phoenix Lander landed successfully on the Martian northern polar region. The mission is part of the National Aeronautics and Space Administration's (NASA's) Scout program. Pressure observations onboard the Phoenix lander were performed by an FMI (Finnish Meteorological Institute) instrument, based on a silicon diaphragm sensor head manufactured by Vaisala Inc., combined with MDA data processing electronics. The pressure instrument performed successfully throughout the Phoenix mission. The pressure instrument had 3 pressure sensor heads. One of these was the primary sensor head and the other two were used for monitoring the condition of the primary sensor head during the mission. During the mission the primary sensor was read with a sampling interval of 2 s and the other two were read less frequently as a check of instrument health. The pressure sensor system had a real-time data-processing and calibration algorithm that allowed the removal of temperature dependent calibration effects. In the same manner as the temperature sensor, a total of 256 data records (8.53 min) were buffered and they could either be stored at full resolution, or processed to provide mean, standard deviation, maximum and minimum values for storage on the Phoenix Lander's Meteorological (MET) unit.The time constant was approximately 3s due to locational constraints and dust filtering requirements. Using algorithms compensating for the time constant effect the temporal resolution was good enough to detect pressure drops associated with the passage of nearby dust devils.
