    Full Text Available O presente artigo busca derivar, a partir da Dialética do Senhor e do Escravo, da Fenomenologia do Espírito de Hegel, a sociologia moderna enquanto ciência essencialmente humana. Assim, a partir do conceito de intersubjetividade que Hegel desenvolve através de sua filosofia do espírito, pretende-se analisar os fundamentos filosóficos dos pensamentos sociológicos de Karl Marx e de Max Weber. Conclui-se, portanto, que tanto o viés revolucionário do Manifesto Comunista, quanto o viés conservador da Ética Protestante, partem, fundamentalmente, do legado filosófico hegeliano.

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.

  3. BUSCA-JUN91 reference manual

    Ramsdale, S.A.; Guentay, S.; Friederichs, H.G.

    1995-02-01

    BUSCA models the decontamination of a bubble as it rises through a water pool. The bubble may contain a mixture of non-condensable gases, steam, iodine vapor and aerosol particles. The bubble thermal-hydraulics are modeled as well as the removal of soluble vapor and aerosol contaminants. The code was originally developed at SRD (part of the UK Atomic Energy Authority) during the mid 1980's. A description of an early version of the code was presented in the BUSCA-JUN90 Reference Manual. Since then, the code has been further enhanced by collaboration within the European Pool Scrubbing Group and additional mechanisms included in its calculations. In particular, PSI (Paul Scherrer Institute, Wuerenlingen) has converted the original FACSIMILE code into FORTRAN and added different bubble initial volume, geometry and bubble rise speed options, UPM (Universidad Politecnica de Madrid) has added the bubble breakup modelling and SRD has added the cluster and plume features. This report describes the BUSCA code version JUN91 which treats the bubble hydrodynamics and removal of aerosol particles and soluble gas in an attempt to calculate the decontamination factor (mass in/mass out), including its input and output requirements. It must be stressed that the development of BUSCA is an on-going project. Currently SRD and PSI have added additional models in their own versions. (author) 3 figs., 39 refs

  4. Simulation of pool scrubbing experiments using BUSCA

    International Nuclear Information System (INIS)

    1994-01-01

    BUSCA-PSI is a computer code which predicts the aerosol scrubbing taking place when gas bubbles containing fission products rise through stagnant pools of water after a postulated severe accident. A Lagrangian formulation is adopted to follow the path of a bubble as it rises toward the surface of the pool. The BUSCA model includes most aerosol removal mechanisms which are thought to be significant, namely: Jet Impaction at tile orifice, Convection/Diffusiophoresis during steam condensation, Thermophoresis, Sedimentation, Centrifugal Impaction during bubble rise, and Brownian Diffusion. The hydraulic modelling offers a variety of options for the initial globule volume, the stable bubble size, tile bubble rise velocity, and the bubble shape. The heat and mass transfer part of tile model uses correlations found in the relevant literature. BUSCA simulations were performed to determine the decontamination factor (DF) dependence on key aerosol and thermal hydraulic parameters. The decontamination factor increases with height, pool temperature subcooling, and steam content. The decontamination factor exhibits a parabolic dependence on the particle radius. At low particle sizes, the DF is high due to Brownian Diffusion which is the dominant removal mechanism. The DF hits a minimum and then increases with particle size as Centrifugal Impaction and Sedimentation become important. In separate calculations, BUSCA was used to the simulate the aerosol scrubbing experiments performed by EPRI. For cold pool tests, the predicted scrubbing efficiencies were in a good, conservative agreement with the data for both Tin and CsI, and the discrepancies were within the reported measurement errors. For hot pool tests, the code systematically underpredicted the scrubbing DF's; this is potentially due to condensation in the gas space above the pool, a situation not currently modelled by BUSCA. The code was also tested against data produced by the Tepco-Toshiba-Hitachi experiments. The

    A proper measurement of the relevant single and two-phase flow parameters is the basis for the understanding of many complex thermal-hydraulic processes. Reliable instrumentation is therefore necessary for the interaction between analysis and experiment especially in the field of nuclear safety research where postulated accident scenarios have to be simulated in experimental facilities and predicted by complex computer code systems. The so-called conventional instrumentation for the measurement of e. g. pressures, temperatures, pressure differences and single phase flow velocities is still a solid basis for the investigation and interpretation of many phenomena and especially for the understanding of the overall system behavior. Measurement data from such instrumentation still serves in many cases as a database for thermal-hydraulic system codes. However some special instrumentation such as online concentration measurement for boric acid in the water phase or for non-condensibles in steam atmosphere as well as flow visualization techniques were further developed and successfully applied during the recent years. Concerning the modeling needs for advanced thermal-hydraulic codes, significant advances have been accomplished in the last few years in the local instrumentation technology for two-phase flow by the application of new sensor techniques, optical or beam methods and electronic technology. This paper will give insight into the current state of instrumentation technology for safety-related thermohydraulic experiments. Advantages and limitations of some measurement processes and systems will be indicated as well as trends and possibilities for further development. Aspects of instrumentation in operating reactors will also be mentioned.

    This chapter reviews the parameters which are important to positron-imaging instruments. It summarizes the options which various groups have explored in designing tomographs and the methods which have been developed to overcome some of the limitations inherent in the technique as well as in present instruments. The chapter is not presented as a defense of positron imaging versus single-photon or other imaging modality, neither does it contain a description of various existing instruments, but rather stresses their common properties and problems. Design parameters which are considered are resolution, sampling requirements, sensitivity, methods of eliminating scattered radiation, random coincidences and attenuation. The implementation of these parameters is considered, with special reference to sampling, choice of detector material, detector ring diameter and shielding and variations in point spread function. Quantitation problems discussed are normalization, and attenuation and random corrections. Present developments mentioned are noise reduction through time-of-flight-assisted tomography and signal to noise improvements through high intrinsic resolution. Extensive bibliography. (U.K.)

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.

    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.

    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 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.

    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.

    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.

    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.

    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.

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

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

    Full Text Available O fenômeno das condutas juvenis tem sido alvo de interesse na ciência social e humana, principalmente aquelas que conduzem à delinqüência. Apesar de inúmeras variáveis conseguirem explicá-lo, o construto busca de sensações vem contribuindo muito para isso, pois ele enfatiza as diferenças individuais. A partir da perspectiva personalística, aponta a avaliação do grau com que os jovens pretendem viver experiências em correr riscos e sua predisposição a sensações de novidades e intensidades. 504 jovens, entre 11 e 20 anos, responderam o questionário de condutas anti-sociais e delitivas e de busca de sensação, de Arnett. Observou-se que a busca de intensidade e de novidades se relacionaram diretamente às condutas anti-sociais e delitivas. Esses resultados permitem supor que as variáveis personalísticas ainda têm bastante contribuição quando se pretende explicar a conduta juvenil delinqüente a partir da orientação de atitudes frente à excitação e ao investimento de atividades permeadoras de risco.

    2015-11-01

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

    Full Text Available Busca em grafos é uma das técnicas mais utilizadas para o projeto de algoritmos em grafos. Em tais buscas, a ordem em que os vértices de um grafo são visitados definem uma enumeração nos vértices do grafo e uma caracterização dessas enumerações que, de acordo com a estratégia usada na busca, tem se mostrado importante nas aplicações de algoritmos em grafos. Neste trabalho generalizamos o conceito de busca e as caracterizações, bem conhecidas no caso de grafos, para o caso de hipergrafo.

    Full Text Available A evolução das tecnologias de comunicação e informação – TIC’s inauguram uma era de crescimento e disseminação exponencial de conteúdo relevante. Com a expansão da ubiqüidade on-line, o crescimento e a facilidade de acesso à web móvel, via dispositivos portáteis, “a busca” popularizou-se e os mecanismos de busca cresceram e se sofisticaram. O presente artigo tem como foco fazer uma atualização das publicações mais recentes das Estratégias de Marketing Digital, ampliando a visibilidade de conceitos e tendências importantes: i evolução da web 2.0 para web semântica ii Marketing de busca, Estratégias SEM e SEO iii móbile tagging, QR codes e Realidade Aumentada. Trata-se de uma pesquisa exploratória e uma investigação secundária, sobretudo bibliográfica, privilegiando publicações em sites especializados, notadamente no período de 1995 a 2010. Algumas inovações tecnológicas se tornaram marcantes e se transformaram em fortes tendências, impactando os profissionais de marketing e de Tecnologia de Informação (TI. A migração do consumo para a web, as facilidades dos mecanismos de buscas por melhores produtos e referências e o aumento do consumo em tempo real, assumem-se como tendências irreversíveis, que exigem das organizações estratégias mercadológicas eficientes. Assim, torna-se imperativo gerenciar a comunicação empresarial na “Era da busca” exigindo uma postura de atualização permanente e estratégias de marketing dirigidas e sustentáveis.

    Full Text Available O paradigma do protagonismo juvenil reconhece nos adolescentes potencialidades e valores de mobilização e participação, os quais podem contribuir para a promoção da saúde e melhor qualidade de vida desta população. O objetivo desta investigação foi conhecer e analisar a participação de adolescentes escolares em atividades de educação em saúde na escola e a sua inserção enquanto sujeitos protagonistas na referidas atividades. O estudo foi realizado em duas escolas municipais de ensino fundamental de Ribeirão Preto, São Paulo, Brasil, no período de fevereiro a junho de 2007. Estudo transversal, a partir de uma abordagem quantitativa, cujos dados incluíram respostas a um questionário com instrumentos validados, e a análise estatística se constituiu basicamente da categorização de variáveis e obtenção das listagens de frequências, realizadas através do Programa Epi Info 3.3.2 (Centers for Disease Control and Prevention, Atlanta, Estados Unidos. Os adolescentes entrevistados apontam que ainda permanecem em uma relação de dependência da escola e dos educadores para a realização e participação de atividades educativas em saúde no espaço escolar. Isto significa dizer que esses adolescentes ainda convivem com uma relação educador-educando unilateral, pouco participativa, indicando uma urgente necessidade de se promover a inclusão desses adolescentes como atores ativos do mundo escolar.

    2017-06-01

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

    2013-12-01

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

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

  2. Instrumentation development

    Ubbes, W.F.; Yow, J.L. Jr.

    1988-01-01

    Instrumentation is developed for the Civilian Radioactive Waste Management Program to meet several different (and sometimes conflicting) objectives. This paper addresses instrumentation development for data needs that are related either directly or indirectly to a repository site, but does not touch on instrumentation for work with waste forms or other materials. Consequently, this implies a relatively large scale for the measurements, and an in situ setting for instrument performance. In this context, instruments are needed for site characterization to define phenomena, develop models, and obtain parameter values, and for later design and performance confirmation testing in the constructed repository. The former set of applications is more immediate, and is driven by the needs of program design and performance assessment activities. A host of general technical and nontechnical issues have arisen to challenge instrumentation development. Instruments can be classed into geomechanical, geohydrologic, or other specialty categories, but these issues cut across artificial classifications. These issues are outlined. Despite this imposing list of issues, several case histories are cited to evaluate progress in the area

  6. 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.

Deste modo, o indivíduo percebe-se como único e capaz de escolher e de sofrer as consequências das suas próprias escolhas e, por isso, o homem se apresenta como inevitavelmente angustiado. Demonstram-se, por conseguinte, os estágios da existência e sua relação com o Cristianismo, contrapondo-se o homem natural ao sobrenatural. Objetiva-se a condução e percepção concreta do homem com sua subjetividade e abertura ao Absoluto.

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

    1976-09-01

    It is essential to any research activity that accurate and efficient measurements be made for the experimental parameters under consideration for each individual experiment or test. Satisfactory measurements in turn depend upon having the necessary instruments and the capability of ensuring that they are performing within their intended specifications. This latter requirement can only be achieved by providing an adequate maintenance facility, staffed with personnel competent to understand the problems associated with instrument adjustment and repair. The Instrument Repair Shop at the Lawrence Berkeley Laboratory is designed to achieve this end. The organization, staffing and operation of this system is discussed. Maintenance policy should be based on studies of (1) preventive vs. catastrophic maintenance, (2) records indicating when equipment should be replaced rather than repaired and (3) priorities established to indicate the order in which equipment should be repaired. Upon establishing a workable maintenance policy, the staff should be instructed so that they may provide appropriate scheduled preventive maintenance, calibration and corrective procedures, and emergency repairs. The education, training and experience of the maintenance staff is discussed along with the organization for an efficient operation. The layout of the various repair shops is described in the light of laboratory space and financial constraints

    Full Text Available This article represents part of a master’s dissertation, whose main objective is to analyze the pedagogical practice of the Biology teacher as an “ecological person” under the aspect of the dimensions that characterize the educational process in Environmental Education - dimension of knowledge, ethical and aesthetic values and political dimension. We conducted semi-structured interviews for the collection of data, supplemented by documentary analysis; a qualitative assessment involving public school teachers was developed in order to explore their personal and professional relationship with the environmental thematic. The data indicated a close relationship between teachers’ degree of proximity to characteristics of the “ecological person” and the dimensions that characterize the Environmental Education expressed in their teaching practice, besides highlighting the opportunities for training teachers as environmental educators. Este artigo apresenta um recorte dos estudos realizados durante o mestrado buscando analisar a prática pedagógica do professor de Biologia enquanto “sujeito ecológico” sob o aspecto das dimensões que caracterizam o processo educativo em Educação Ambiental - dimensão dos conhecimentos, dos valores éticos e estéticos e dimensão política. Por meio do emprego de entrevistas semiestruturadas complementadas por análise documental, desenvolvemos uma pesquisa qualitativa envolvendo docentes do ensino público, no intuito de explorar seu relacionamento pessoal e profissional com a temática ambiental. Os dados obtidos revelaram uma estreita relação entre o grau de aproximação do professor em relação às características que compõem o “sujeito ecológico” e as dimensões que caracterizam os trabalhos em Educação Ambiental expressas em sua prática docente além de apontar caminhos para a formação dos professores enquanto educadores ambientais.

    Full Text Available Introdução: O processo de busca faz parte da sociedade atual e os mecanismos de busca são os responsáveis pela indexação e elaboração dos índices contemporâneos no ciberespaço.Objetivo: Neste trabalho, a tradução intersemiótica verbo-visual do Google Images e oSKope, considerados híbridos por misturar linguagens, foi analisada visando avaliar o nível de equivalência dos signos nos resultados.Metodologia: A partir da categorização dos mecanismos, o paradigma semiótico vem sendo perscrutado, visando entender as matrizes da linguagem-pensamento, de Santaella, no funcionamento dos buscadores. 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.

    Full Text Available Verifica as características do processo de busca de informação realizado por professores/pesquisadores da área da Psicologia, da Universidade do Vale do Rio dos Sinos - Unisinos. 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.

    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.

    International Nuclear Information System (INIS)

    Kronenberg, S.; McLaughlin, W.L.; Seibentritt, C.R. Jr.

    1986-01-01

    An instrument is described for measuring radiation, particularly nuclear radiation, comprising: a radiation sensitive structure pivoted toward one end and including a pair of elongated solid members contiguously joined together along their length dimensions and having a common planar interface therebetween. One of the pairs of members is comprised of radiochromic material whose index of refraction changes due to anomolous dispersion as a result of being exposed to nuclear radiation. The pair of members further has mutually different indices of refraction with the member having the larger index of refraction further being transparent for the passage of light and of energy therethrough; means located toward the other end of the structure for varying the angle of longitudinal elevation of the pair of members; means for generating and projecting a beam of light into one end of the member having the larger index of refraction. The beam of light is projected toward the planar interface where it is reflected out of the other end of the same member as a first output beam; means projecting a portion of the beam of light into one end of the member having the larger index of refraction where it traverses therethrough without reflection and out of the other end of the same member as a second output beam; and means adjacent the structure for receiving the first and second output beams, whereby a calibrated change in the angle of elevation of the structure between positions of equal intensity of the first and second output beams prior to and following exposure provides a measure of the radiation sensed due to a change of refraction of the radiochromic material

    Full Text Available Este trabajo examina la construcción narrativa de la Patagonia en la obra La tierra del fuego (1998 de Sylvia Iparraguirre. 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.

    2016-07-01

    Full Text Available O trabalho objetiva investigar de que maneira o indivíduo, principalmente, o velho, pode enfrentar de modo eficaz e adequado os desafios que se apresentam no decorrer do caminho da existência. Tem por base uma revisão da literatura especializada dos subsídios teóricos da Psicologia Positiva e da Logoterapia, segundo os quais é possível aprender a ser resiliente, como também aumentar, fortalecer e desenvolver o nível de resiliência, por meio do desenvolvimento de recursos internos, tendo em vista que os desafios que o velho encontra ao longo da vida podem ser reconhecidos como oportunidades para a adoção de decisões melhores e mais responsáveis, mantendo-se íntegro nas adversidades, não só superando-as, mas se transformando, crescendo e reinventando-se a partir das mesmas. Infere-se que a proposta de atuação do psicólogo na velhice visa à ajuda na construção conjunta de estratégias alternativas para o enfrentamento dos desafios da vida cotidiana, já que esse último estágio do ciclo de vida é marcado por inúmeras perdas nos âmbitos biopsicosociocultural, o que torna imprescindível tanto o resgate do bem-estar psicológico, como a busca de sentido de vida do indivíduo velho.

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

    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.

    In considering the appropriate use of the terms "science" and "scientific instrument," tracing the history of "mathematical instruments" in the early modern period is offered as an illuminating alternative to the historian's natural instinct to follow the guiding lights of originality and innovation, even if the trail transgresses contemporary boundaries. The mathematical instrument was a well-defined category, shared across the academic, artisanal, and commercial aspects of instrumentation, and its narrative from the sixteenth to the eighteenth century was largely independent from other classes of device, in a period when a "scientific" instrument was unheard of.

    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.

    Westinghouse Hanford Company Project W-211 is responsible for providing the system capabilities to remove radioactive waste from ten double-shell tanks used to store radioactive wastes on the Hanford Site in Richland, Washington. The project is also responsible for measuring tank waste slurry properties prior to injection into pipeline systems, including the Replacement of Cross-Site Transfer System. This report summarizes studies of the appropriateness of the instrumentation specified for use in Project W-211. The instruments were evaluated in a test loop with simulated slurries that covered the range of properties specified in the functional design criteria. The results of the study indicate that the compact nature of the baseline Project W-211 loop does not result in reduced instrumental accuracy resulting from poor flow profile development. Of the baseline instrumentation, the Micromotion densimeter, the Moore Industries thermocouple, the Fischer and Porter magnetic flow meter, and the Red Valve Pressure transducer meet the desired instrumental accuracy. An alternate magnetic flow meter (Yokagawa) gave nearly identical results as the baseline fischer and Porter. The Micromotion flow meter did not meet the desired instrument accuracy but could potentially be calibrated so that it would meet the criteria. The Nametre on-line viscometer did not meet the desired instrumental accuracy and is not recommended as a quantitative instrument although it does provide qualitative information. The recommended minimum set of instrumentation necessary to ensure the slurry meets the Project W-058 acceptance criteria is the Micromotion mass flow meter and delta pressure cells

    Deficiencies exist in both the performance and the quality of health physics instruments. Recognizing the implications of such deficiencies for the protection of workers and the public, in the early 1980s the DOE and the NRC encouraged the development of a performance standard and established a program to test a series of instruments against criteria in the standard. The purpose of the testing was to establish the practicality of the criteria in the standard, to determine the performance of a cross section of available instruments, and to establish a testing capability. Over 100 instruments were tested, resulting in a practical standard and an understanding of the deficiencies in available instruments. In parallel with the instrument testing, a value-impact study clearly established the benefits of implementing a formal testing program. An ad hoc committee also met several times to establish recommendations for the voluntary implementation of a testing program based on the studies and the performance standard. For several reasons, a formal program did not materialize. Ongoing tests and studies have supported the development of specific instruments and have helped specific clients understand the performance of their instruments. The purpose of this presentation is to trace the history of instrument testing to date and suggest the benefits of a centralized formal program

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

A pesquisa foi conduzida segundo a abordagem qualitativa, com base na Fenomenologia. A coleta de dados ocorreu por meio de entrevistas individuais, adotando-se para o processo analítico, o método proposto por Giorgi (1985, composto de quatro passos e que parte dos depoimentos da experiência vivida para chegar à compreensão do fenômeno. Os resultados obtidos indicaram que o trabalho assume para cada indivíduo, um significado, uma função, relacionada aos seus desejos e necessidades, o que o transforma, portanto, num instrumento para realização dessas pessoas. O estudo permitiu ainda a identificação de 10 categorias de significado, que vão ao encontro dos resultados obtidos pelo Meaning of Working – MOW (1987 – sobre o tema. Constatou-se também que à medida que o trabalho consegue cumprir sua função, ou seja, quando é provido de significado para o indivíduo, há um sentimento de gratificação e prazer, o que leva à reflexão sobre a importância de estudos sobre o Significado do Trabalho, cujos resultados beneficiam: 1 os profissionais, pois as investigações levam a um questionar-se e, portanto, à busca de um maior conhecimento dos próprios desejos e necessidades, com conseqüente envolvimento com as atividades mais significativas; 2 as empresas, que podem buscar um maior ajuste entre os objetivos organizacionais e as expectativas dos indivíduos, resultando em qualidade, sinergia e eficácia.ABSTRACTThe present article is derived from of a study accomplished in a group of managers which objective aimed at understanding the meaning attributed by them to the work they perform.

    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 OBJETIVO: Em situações estressantes, as pessoas geralmente usam os dedos para retirar corpos estranhos de faringe da boca. 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.

    A properly conditioned AC power supply is necessary for reliable functioning of instruments. Electric mains power is produced primarily for industry, workshops, lighting and household uses. Its quality is adjusted to these uses. In areas sand countries with a fast growing demand for electric power, these requirements are far from being met. Electronic instruments and computers, especially in these countries, need protection against disturbances of the mains supply. A clean and dry environment is needed for reliable functioning and long life of instruments. High humidity, specially at higher temperatures, changes the characteristics of electronic components. Moreover, under these conditions fungal growth causes leakage of currents and corrosion causes poor contacts. The presence of dust enhances these effects. They give rise to malfunction of instruments, particularly of high voltage equipment

    This paper reports on Nuclear Instrument Technician (NIT) training that has developed at an accelerated rate over the past three decades. During the 1960's commercial nuclear power plants were in their infancy. For that reason, there is little wonder that NIT training had little structure and little creditability. NIT training, in many early plants, was little more than On-The Job Training (OJT). The seventies brought changes in Instrumentation and Controls as well as emphasis on the requirements for more in depth training and documentation. As in the seventies, the eighties saw not only changes in technologies but tighter requirements, standardized training and the development of accredited Nuclear Instrument Training; thus the conclusion: Nuclear Instrument Training Isn't What It Used To Be

    The science objectives for proposed NASA missions for the next decades push the state of the art in sensitivity and spatial resolution over a wide range of wavelengths, including the x-ray to the submillimeter. While some of the proposed missions are larger and more sensitive versions of familiar concepts, such as the next generation space telescope, others use concepts, common on the Earth, but new to space, such as optical interferometry, in order to provide spatial resolutions impossible with other concepts. However, despite their architecture, the performance of all of the proposed missions depends critically on the back-end instruments that process the collected energy to produce scientifically interesting outputs. The Advanced Optical Instruments Technology panel was chartered with defining technology development plans that would best improve optical instrument performance for future astrophysics missions. At this workshop the optical instrument was defined as the set of optical components that reimage the light from the telescope onto the detectors to provide information about the spatial, spectral, and polarization properties of the light. This definition was used to distinguish the optical instrument technology issues from those associated with the telescope, which were covered by a separate panel. The panel identified several areas for optical component technology development: diffraction gratings; tunable filters; interferometric beam combiners; optical materials; and fiber optics. The panel also determined that stray light suppression instruments, such as coronagraphs and nulling interferometers, were in need of general development to support future astrophysics needs.

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

    Many radiological surveillance instruments are in use at DOE facilities throughout the country. These instruments are an essential part of all health physics programs, and poor instrument performance can increase program costs or compromise program effectiveness. Generic data from simple tests on newly purchased instruments shows that many instruments will not meet requirements due to manufacturing defects. In other cases, lack of consideration of instrument use has resulted in poor acceptance of instruments and poor reliability. The performance of instruments is highly variable for electronic and mechanical performance, radiation response, susceptibility to interferences and response to environmental factors. Poor instrument performance in these areas can lead to errors or poor accuracy in measurements

Foram identificados, neste contexto: o tratamento da depressão no serviço (do encaminhamento ao atendimento, as noções de doença elaboradas pelas mulheres e o consumo de medicamentos. Ficaram evidentes: a banalização da depressão, a importância do psiquiatra e do uso de antidepressivos e ansiolíticos no tratamento. Os padrões encontrados de consumo dos medicamentos pelas mulheres sugerem a ocorrência de uma "toxicomania medicamentosa". O uso de medicamentos, além da ação farmacológica, possui uma ação simbólica, no sentido de conforto e cuidado. O trabalho aponta para a necessidade de se articularem o significado das experiências das mulheres e as abordagens terapêuticas da depressão na construção das políticas públicas de saúde mental.

    The widespread release of activity and the resultant spread of contamination after the Chernobyl accident resulted in requests to NRPB to provide instruments for, and expertise in, the measurement of radiation. The most common request was for advice on the usefulness of existing instruments, but Board staff were also involved in their adaptation or in the development of new instruments specially to meet the circumstances of the accident. The accident occurred on 26 April. On 1 May, NRPB was involved at Heathrow Airport in the monitoring of the British students who had returned from Kiev and Minsk. The main purpose was to reassure the students by checking that their persons and belongings did not have significant surface contamination. Additional measurements were also made of iodine activity in thyroid using hand-held detectors or a mobile body monitor. This operation was arranged with the Foreign and Commonwealth Office, which had also received numerous requests for instruments from embassies and consulates in countries close to the scene of the accident. There was concern for the well-being of staff and other United Kingdom nationals who resided in or intended to visit the most affected countries. The board supplied suitable instruments, and the FCO distributed them to embassies. The frequency of environmental monitoring was increased from 29 April in anticipation of contamination and appropriate Board instrumentation was deployed. After the Chernobyl cloud arrived in the UK on 2 May, there were numerous requests from local government, public authorities, private companies and members of the public for information and advice on monitoring equipment and procedures. Some of these requirements could be met with existing equipment but members of the public were usually advised not to proceed. At a later stage, the contamination of foodstuffs and livestock required the development of an instrument capable of detecting low levels of {sup 137}Cs and {sup 134}Cs in food

  13. Reactor instrumentation and control

    1980-01-01

    The methods for measuring radiation are shortly reviewed. The instrumentation for neutron flux measurement is classified into out-of-core and in-core instrumentation. The out-of-core instrumentation monitors the operational range from the subcritical reactor to full power. This large range is covered by several measurement channels which derive their signals from counter tubes and ionization chambers. The in-core instrumentation provides more detailed information on the power distribution in the core. The self-powered neutron detectors and the aeroball system in PWR reactors are discussed. Temperature and pressure measurement devices are briefly discussed. The different methods for leak detection are described. In concluding the plant instrumentation part some new monitoring systems and analysis methods are presented: early failure detection methods by noise analysis, acoustic monitoring and vibration monitoring. The presentation of the control starts from an qualitative assessment of the reactor dynamics. The chosen control strategy leads to the definition of the part-load diagram, which provides the set-points for the different control systems. The tasks and the functions of these control systems are described. In additiion to the control, a number of limiting systems is employed to keep the reactor in a safe operating region. Finally, an outlook is given on future developments in control, concerning mainly the increased application of process computers. (orig./RW)

  14. Instrumental analysis, second edition

    International Nuclear Information System (INIS)

    Christian, G.D.; O'Reilly, J.E.

    1988-01-01

    The second edition of Instrumental Analysis is a survey of the major instrument-based methods of chemical analysis. It appears to be aimed at undergraduates but would be equally useful in a graduate course. The volume explores all of the classical quantitative methods and contains sections on techniques that usually are not included in a semester course in instrumentation (such as electron spectroscopy and the kinetic methods). Adequate coverage of all of the methods contained in this book would require several semesters of focused study. The 25 chapters were written by different authors, yet the style throughout the book is more uniform than in the earlier edition. With the exception of a two-chapter course in analog and digital circuits, the book purports to de-emphasize instrumentation, focusing more on the theory behind the methods and the application of the methods to analytical problems. However, a detailed analysis of the instruments used in each method is by no means absent. The book has the favor of a user's guide to analysis

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

    1982-01-01

    Protective Instrumentation (PI) for Nuclear Power Plants (NPP) is a general term for an highly reliable instrumentation, which provides information for keeping the system within safe limits, for initation of countermeasures in the case of an incident or for mitigation of consequences of an accident. In German NPPs one can find a hierarchical structure of protective instrumentation, wherein the Reactor Protection System (RPS) has the highest priority. To meet the reliability requirements different design principles are used, like - redundancy - diversity - fail safe - decoupling. The presentation gives an overview about the different design principles and characterizes their reliability aspects. As an example for the technical realization the RPS of a German NPP is discussed in some detail. Furthermore some information about other type of PI is given and reliability aspects of the interaction of operating personell with these systems are mentioned. (orig.)

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

    Full Text Available The rules laid down by Romanian Capital Market Law and the regulations put in force for its implementation apply to issuers of financial instruments admitted to trading on the regulated market established in Romania. 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. Thus issuers are, in Romanian Law perspective, special company that should comply special rule regarding board of administration and general shareholders meeting.

    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.

    The Advanced Nuclear Technology Group of the Los Alamos National Laboratory is now using intelligent data-acquisition and analysis instrumentation for determining the multiplication of nuclear material. Earlier instrumentation, such as the large NIM-crate systems, depended on house power and required additional computation to determine multiplication or to estimate error. The portable, battery-powered multiplication measurement unit, with advanced computational power, acquires data, calculates multiplication, and completes error analysis automatically. Thus, the multiplication is determined easily and an available error estimate enables the user to judge the significance of results

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

    Power stations are characterized by a wide variety of mechanical and electrical plant operating with structures, liquids and gases working at high pressures and temperatures and with large mass flows. The voltages and currents are also the highest that occur in most industries. In order to achieve maximum economy, the plant is operated with relatively small margins from conditions that can cause rapid plant damage, safety implications, and very high financial penalties. In common with other process industries, power stations depend heavily on control and instrumentation. These systems have become particularly significant, in the cost-conscious privatized environment, for providing the means to implement the automation implicit in maintaining safety standards, improving generation efficiency and reducing operating manpower costs. This book is for professional instrumentation engineers who need to known about their use in power stations and power station engineers requiring information about the principles and choice of instrumentation available. There are 8 chapters; chapter 4 on instrumentation for nuclear steam supply systems is indexed separately. (Author)

    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.

    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).

    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

  15. Developments in analytical instrumentation

    Science.gov (United States)

    Petrie, G.

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

    Armitage, D. Bruce

    1999-02-01

    This simulator was developed to help students beginning the study of gas chromatographic instruments to understand their operation. It is not meant to teach chromatographic theory. The instrument simulator is divided into 5 sections. One is for sample preparation. Another is used to manage carrier gases and choose a detector and column. The third sets the conditions for either isothermal or programmed temperature operation. A fourth section models manual injections, and the fifth is the autosampler. The operator has a choice among 6 columns of differing diameters and packing polarities and a choice of either isothermal or simple one-stage temperature programming. The simulator can be operated in either single-sample mode or as a 10-sample autosampler. The integrator has two modes of operation, a "dumb" mode in which only the retention time, area of the peak, and percentage area are listed and a "smart" mode that also lists the components' identities. The identities are obtained from a list of names and retention times created by the operator. Without this list only the percentages and areas are listed. The percentages are based on the areas obtained from the chromatogram and not on the actual percentages assigned during sample preparation. The data files for the compounds used in the simulator are ASCII files and can be edited easily to add more compounds than the 11 included with the simulator. A maximum of 10 components can be used in any one sample. Sample mixtures can be made on a percent-by-volume basis, but not by mass of sample per volume of solvent. A maximum of 30 compounds can be present in any one file, but the number of files is limited only by the operating system. (I suggest that not more than 20 compounds be used in any one file, as scrolling through large numbers of compounds is annoying to say the least.) File construction and layout are discussed in detail in the User's Manual. Chromatograms are generated by calculating a retention time based on

Although responsible business notion is generally known, its details, ways of preparing strategy, instruments and what is more its benefits are still narrowly spread. Many business people face the lack of knowledge and information, which on one hand make it easier to spread and deepen wrong stereotypes connected with this notion and on the other hand make business people unwilling to implement CRS in their companies.

    The core safety during operation is linked, in particular, to the respect of criteria related to the heat generated in fuel rods and to the heat exchange between the rods and the coolant. This local power information is linked to the power distribution in the core. In order to evaluate the core power distribution, the EPR TM reactor relies on several types of neutron detectors: - ionization chambers located outside the vessel and used for protection and monitoring - a fixed in-core instrumentation based on Cobalt Self Powered Neutron Detectors used for protection and monitoring - a mobile reference in-core instrumentation based on Vanadium aero-balls This document provides a description of this instrumentation and its use in core protection, limitation, monitoring and control functions. In particular, a description of the detectors and the principles of their signal generation is supplied as well as the description of the treatments related to these detectors in the EPR TM reactor I and C systems (including periodical calibration).

  4. Mandolin Family Instruments

    Science.gov (United States)

    Cohen, David J.; Rossing, Thomas D.

    The mandolin family of instruments consists of plucked chordophones, each having eight strings in four double courses. With the exception of the mandobass, the courses are tuned in intervals of fifths, as are the strings in violin family instruments. The soprano member of the family is the mandolin, tuned G3-D4-A4-E5. The alto member of the family is the mandola, tuned C3-G3-D4-A4. The mandola is usually referred to simply as the mandola in the USA, but is called the tenor mandola in Europe. The tenor member of the family is the octave mandolin, tuned G2-D3-A3-E4. It is referred to as the octave mandolin in the USA, and as the octave mandola in Europe. The baritone member of the family is the mandocello, or mandoloncello, tuned C2-G2-D3-A3. A variant of the mandocello not common in the USA is the five-course liuto moderno, or simply liuto, designed for solo repertoire. Its courses are tuned C2-G2-D3-A3-E4. A mandobass was also made by more than one manufacturer during the early twentieth century, though none are manufactured today. They were fretted instruments with single string courses tuned E1-A1-D2-G2. There are currently a few luthiers making piccolo mandolins, tuned C4-G4-D5-A5.

    Reference is made to the instrumentation of liquid metal cooled fast reactors. In order to ensure the safe operation of such reactors it is necessary to constantly monitor the coolant flowing through the fuel assemblies for temperature and rate of flow, requiring a large number of sensors. An improved and simplified arrangement is claimed in which the fuel assemblies feed a fraction of coolant to three instrument units arranged to sense the temperature and rate of flow of samples of coolant. Each instrument unit comprises a sleeve housing a sensing unit and has a number of inlet ducts arranged for receiving coolant from a fuel assembly together with a single outlet. The sensing unit has three thermocouple hot junctions connected in series, the hot junctions and inlet ducts being arranged in pairs. Electromagnetic windings around an inductive core are arranged to sense variation in flow of liquid metal by flux distortion. Fission product sensing means may also be provided. Full constructional details are given. (U.K.)

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.

    Full Text Available Um estudo clínico-epidemiológico, do tipo relato de casos, avaliou o sistema de vigilância e busca ativa de casos suspeitos de dengue hemorrágico/síndrome de choque do dengue (DH/SCD durante uma epidemia de dengue no Município de Ribeirão Preto, Estado de São Paulo, Brasil, que ocorreu entre novembro de 1990 e março de 1991. Tratou-se da primeira epidemia de dengue registrada nessa região. Embora o dengue seja um problema de saúde pública crescente no Brasil e o DH/SCD pareça tratar-se de um problema em evolução nas Américas, os serviços de saúde pública demonstram uma atitude passiva diante da ocorrência da doença, em parte como fruto da falta de experiência. A divulgação da ocorrência desta enfermidade, tanto na forma de casos esporádicos como na forma epidêmica, é essencial para a redução da letalidade. Os dados utilizados na presente análise foram coletados pelo sistema oficial de vigilância epidemiológica do Município de Ribeirão Preto durante o período da epidemia. Entre 2 521 casos confirmados de dengue foram identificados 36 casos suspeitos de DH/SCD -- 34 casos de doença febril aguda com manifestações hemorrágicas e 2 óbitos associados ao dengue. Desse conjunto, 12 casos de dengue com manifestações hemorrágicas foram confirmados laboratorialmente. A análise dos dados clínicos, epidemiológicos, laboratoriais e de autópsia dos óbitos associados ao dengue sugeriu tratarem-se de casos de DH/SCD primário. O estudo aqui descrito evidenciou a dificuldade do sistema assistencial de saúde em estabelecer a suspeita clínica de DH/SCD. Isto acarretou demora e inadequação na conduta clínica. Além disso, ficou confirmada a necessidade de um sistema de vigilância epidemiológica ativa permanente, que possibilite a identificação precoce dos casos suspeitos de DH/SCD e viabilize uma ação de controle rápida e adequada.

    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

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

    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 neutron instrumentation system of this invention can greatly reduce the possibility that the shutdown flux is increased greater than a predetermiend value to cause scram due to vibrations caused by earthquakes or shocks in the neutron instrumentation system without injuring the reactor safety. That is, a sensor having a zero sensitivity to a neutron flux which is an object to be detected by the sensor (dummy sensor) is used together with a conventional sensor (a sensor having predetermined sensitivity to a neutron flux as an object to be measured ----- true sensor). Further, identical signal transmission cables, connector and the signal processing circuits are used for both of true sensor and the dummy sensor. The signal from the dummy sensor is subtracted from the signal from the true sensor at the output of the signal processing circuit. Since the output of the dummy sensor is zero during normal operation, the subtracted value is the same as the value from the true sensor. If the true sensor causes an output with the reason other than the neutron flux, this is outputted also from the dummy sensor but does not appear in the subtracted value. (I.S.)

In addition, an information processing section comprising a man-machine function program formed so as to recognize the content of the operation indication for the incore measurement by touching and let the control section to conduct it is disposed to the outside by way of a communication interface. In addition, a programming device is disposed for forming and rewriting the program of the man-machine function relative to the information processing section. Then, when various indication operations are conducted upon performing incore measurement, a view point can be concentrated to one predetermined point thereby enabling to improve the operationability without danger. In addition, the programming of the man-machine function does not apply unnecessary load to the control section in the incore instrumentation device. (N.H.)

    1998-01-01

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

    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 Fusion Materials Irradiation Test facility (FMIT) cw prototype accelerator has noninterceptive beamline instrumentation to measure beam parameters. The transverse emittances and beam profiles are measured with an array of photodiode sensors viewing light emitted from the beam region. Tomographic reconstructions of both spatial-density distributions and of transverse-emittance distributions are performed throughout a quadrupole focusing section. Beam bunches passing through capacitive probes produce bipolar waveforms whose zero crossing corresponds to the bunch's longitudinal centroid. By measuring the time required for a bunch to travel the known distance between two probes, velocity and energy are determined. A toroidal transformer measures the average ac beam current. Beam spill is measured by a set of movable jaws that intercept the beam edges. Each jaw contains a water flow channel whose flow rate and differential temperature are measured to derive a transverse power distribution. Beam centroid position is measured by a four-lobe, magnetic-loop pickup. 5 refs., 6 figs

    2007-12-01

    Comments on the article by J. T. Jost, which argued that the end-of-ideology claims that emerged in the aftermath of World War II were both incorrect and detrimental to the field of political psychology. M. Glassman and D. Karno make three critical points. First, Jost objectified ideology as a grand strategy implemented at the individual level, rather than as an instrument used for a specific purpose in activity. In doing so, he set ideology up as an "object" that guides human behavior rather than as a rational part of human experience. Second, they take issue with the idea that, because somebody acts in a manner that can be categorized as ideological, there actually is such a thing as ideology separate from that event and/or political experience and that psychologists ought to understand the meaning of ideology in order to understand future human activities as outside observers. Third, Jost seems to see this objective ideology as a unidirectional, causal mechanism for activity, a mechanism that assumes individuals act according to ideology, which eclipses the possibility that immediate ideological positions are the residue of purposeful activity. Glassman and Karno suggest that it may be better to take a pluralistic view of ideology in human action. Where ideology does exist, it is as a purposeful instrument--part of a logically based action to meet some ends-in-view--a mixture of immediate goals tied to secondary belief systems (which have been integrated to serve the material purposes of the purveyors of these ideologies). So if we are to understand ideology, we can only understand it through its use in human activity. (Copyright) 2007 APA.

    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.

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

  9. TFTR CAMAC instrumentation system

    1983-01-01

    The TFTR Central Instrumentation Control and Data Acquisition (CICADA) system makes extensive use of CAMAC equipment. The system consists of eight CAMAC highways operating from eight Gould 75/32 computers. Links up to 3.5 miles in length with more than fifty CAMAC crates have been implemented and are currently in use. Data transfer along the highway is implemented in bit serial format. The link speed is run at 5MHz. The length and complexity of the link requires the reformatting of the NRZ input/output format of the L-2 crate controller. U-Port adapter modules are used to interface the modified serial highway to the L-2 controllers. The modified serial highway uses a transmission technique that requires the distribution of both Bi-Phase encoded data and a 5MHz clock. The Serial Driver interfaces to the GOULD computer through use of a High Speed Data (HSD) interface board which attaches to the computers internal bus. All transfers to and from the computer are accomplished by direct memory access (DMA). In addition to the standard CAMAC link the system also includes a Block Transfer (BT) system. This system provides an alternate path for transferring data between the computers and the CAMAC modules. The BT system is interfaced to the host computers through HSD boards and to the CAMAC crates through use of an auxiliary crate controllers

  10. Detectors for Tomorrow's Instruments

    Moseley, Harvey

    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.

    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.

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

    2016-05-27

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

    The advances in the field of computer and communications are leading to the development of smart embedded nuclear instruments. These instruments have highly sophisticated signal-processing algorithms based on FPGA and ASICS, provisions of present day connectivity and user interfaces. The developments in the connectivity, standards and bus technologies have made possible to access these instruments on LAN and WAN with suitable reliability and security. To get rid of wires i.e. in order to access these instruments, without wires at any place, wireless technology has evolved and become integral part of day-to-day activities. The environment monitoring can be done remotely, if smart antennas are incorporated on these instruments

  4. How discriminating are discriminative instruments?

    Hankins, Matthew

    2008-05-27

    The McMaster framework introduced by Kirshner & Guyatt is the dominant paradigm for the development of measures of health status and health-related quality of life (HRQL). The framework defines the functions of such instruments as evaluative, predictive or discriminative. Evaluative instruments are required to be sensitive to change (responsiveness), but there is no corresponding index of the degree to which discriminative instruments are sensitive to cross-sectional differences. This paper argues that indices of validity and reliability are not sufficient to demonstrate that a discriminative instrument performs its function of discriminating between individuals, and that the McMaster framework would be augmented by the addition of a separate index of discrimination. The coefficient proposed by Ferguson (Delta) is easily adapted to HRQL instruments and is a direct, non-parametric index of the degree to which an instrument distinguishes between individuals. While Delta should prove useful in the development and evaluation of discriminative instruments, further research is required to elucidate the relationship between the measurement properties of discrimination, reliability and responsiveness.

    1986-01-01

    There can be many reasons for applying retrofit designs to existing power plants. Whatever the reasons, care in planning and instrument design will be required in order to derive the full benefits afforded by today's technology. Specifically, the availability of microprocessors and their related integrated circuits make possible capabilities, accuracies, reliabilities, maintainability and user interfaces not achievable when original equipment was designed. Some of the motives for the replacement of current instrumentation are examined and the various benefits and pitfalls of applying present day microprocessor technology to new designs are discussed. From this, a set of design objectives can be formulated that can best take advantage of modern technology. General Electric's design solution, a family of instruments called NUMAC (Nuclear Measurement, Analysis and Control) is described, followed by descriptions of instruments currently in production and those contemplated for design in the near future

    A joint International Chamber of Commerce (ICC)/World Energy Council (WEC) Working Group has been studying a range of policy instruments which are being used or considered for use to address the question of ever increasing energy demand versus environmental protection, and pollution reduction. Economic instruments for such environmental protection include direct regulation, market-based instruments, and voluntary approaches. No single policy or device was likely to suffice in addressing the diversity of environmental problems currently faced. Altering energy prices must be seen in a social context, but some direct regulation may also be inevitable. Generally economic instruments of change were preferred as these were viewed as more flexible and cost-effective. (UK)

    2016-05-01

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

    In the steel industry, though the investment in isotope-equipped measuring instruments is small as compared with that in machinery, they play important role in the moisture measurement in sintering and blast furnaces, the thickness measurement in rolling process and others in automatic control systems. The economic aspect of the isotope-equipped measuring instruments is described on the basis of the practices in Kimitsu Works of Nippon Steel Corporation: distribution of such instruments, evaluation of economic effects, usefulness evaluation in view of raising the accuracy, and usefulness evaluation viewed from the failure of the isotope instruments. The evaluation of economic effects was made under the premise that the isotope-equipped measuring instruments are not employed. Then, the effects of raising the accuracy are evaluated for a γ-ray plate thickness gauge and a neutron moisture gauge for coke in a blast furnace. Finally, the usefulness was evaluated, assuming possible failure of the isotope-equipped measuring instruments. (J.P.N.)

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

    Instruments are essential for accounting, for surveillance and for protection of nuclear materials. The development and application of such instrumentation is reviewed, with special attention to international safeguards applications. Active and passive nondestructive assay techniques are some 25 years of age. The important advances have been in learning how to use them effectively for specific applications, accompanied by major advances in radiation detectors, electronics, and, more recently, in mini-computers. The progress in seals has been disappointingly slow. Surveillance cameras have been widely used for many applications other than safeguards. The revolution in TV technology will have important implications. More sophisticated containment/surveillance equipment is being developed but has yet to be exploited. On the basis of this history, some expectations for instrumentation in the near future are presented

    An at-line solution assay instrument (SAI) has been developed and installed in a plutonium purification and americium recovery process area in the Los Alamos Plutonium Processing Facility. The instrument was designed for accurate, timely, and simultaneous nondestructive analysis of plutonium and americium in process solutions that have a wide range of concentrations and americium/plutonium ratios and for routine operation by process technicians who lack instrumentation background. The SAI, based on transmission-corrected, high-resolution gamma-ray spectroscopy, has two measurement stations attached to a single multichannel analyzer/computer system. To ensure the quality of assay results, the SAI has an internal measurement control program, which requires daily and weekly check runs and monitors key aspects of all assay runs. For a 25-ml sample, the assay precision is 5 g/l within a 2000-s count time

    Full text : Nuclear Instrumentation is a field of vital importance for DAE. It has important applications in many areas of interest such as Reactor Monitoring and control, Accelerator based research, Laser and nuclear physics experiments, Health and environmental monitoring, Astrophysics experiments etc. It is a specialized field involving expertise in detection of radioactivity down to the level of few events per minute as well as processing and analysis of signals which can be as small as few hundred micro volts embedded in noise. Some applications involve digitizing and processing these signals with 0.001% accuracy and timing accuracies of a fraction of nano sec. Rapid developments in semiconductor related technologies have influenced the field of nuclear instrumentation. Development of FPGA's and ASIC's have made it possible to develop miniaturized smart and portable instruments for field applications. Advancements in field of computers, communications and various field buses have been successfully utilized for smart, portable and DSP based instrumentation. Smart sensor with detector and front-end electronics on a single silicon chip is now a reality. These instruments are also made intelligent by addition of fuzzy logic, artificial neural networks and expert systems. Electronics Division of BARC has made significant contribution to the field of nuclear instrumentation to achieve self-reliance in this area. This has also led to development of several new methods, which have been published in international journals and appreciated worldwide. As a step towards achieving complete self-reliance a programme for development of FPGA's, HMC's and ASIC's has been undertaken and is being followed with special emphasis. This also includes development of detector and front- end electronics on a single chip. This talk brings out details of these developments and describes the 'state of art' work done in India

    The Advanced Nuclear Technology Group of the Los Alamos National Laboratory is now using intelligent data-acquisition and analysis instrumentation for determining the multiplication of nuclear material. Earlier instrumentation, such as the large NIM-crate systems, depended on house power and required additional computation to determine multiplication or to estimate error. The portable, battery-powered multiplication measurement unit, with advanced computational power, acquires data, calculates multiplication, and completes error analysis automatically. Thus, the multiplication is determined easily and an available error estimate enables the user to judge the significance of results.

    Astronomers have always attempted to build very stable instruments. They fight all that can cause mechanical deformation or image motion. This has led to well established technologies (autoguide, active optics, thermal control, tip/tilt correction), as well as observing methods based on the use of controlled motion (scanning, micro scanning, shift and add, chopping and nodding). Formation flying disturbs this practice. It is neither possible to reduce the relative motion to very small amplitudes, nor to control it at will. Some impacts on Simbol-X instrument design, and operation are presented.

    Though a century old, the radiation protection is actual by its purpose: a dose as low as reasonable achievable is to be received either by involved professionals or population. This threshold is dependent on the technical progress. Some major developments like surface mounted device technology, consumer almost ideal operational amplifiers, microcontrollers and the news signal digital processing techniques, offer the opportunity to design improved instruments for radioprotection. To put in a light portable instrument both the whole measuring system and the 'intelligence' - a microcontroller and the associated software - are the main ideas applied by the authors. The result is presented: a family of eight members, at least, based on two parents. (authors)

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

    Maintenance of instruments is generally of two kinds: (a) corrective maintenance, on a non-scheduled basis, to restore equipment to a functional status by repairs; (b) preventive maintenance, to keep equipment in a specified functional condition by providing systematic inspection, quality control, detection and correction of early malfunctions. Most of the instruments used in nuclear medicine are rather complex systems built from mechanical, electrical and electronic parts. Any one of these components is liable to fail at some time or other. Repair could be done only by a specialist who is able to evaluate the condition of the various parts ranging from cables to connectors, from scintillators to photomultipliers, from microprocessors to microswitches. The knowledge of the intricacies of the various electronic components required for their repairs is quite wide and varied. The electronics industry turns out more and more multi-purpose chips which can carry out the functions of many parts used in the instruments of the earlier generation. This provides protection against unauthorized copying of the circuits but it serves another purpose as well of inhibiting repairs by non-factory personnel.

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.

    Pott, J.; Brechtel, C.E.

    1992-01-01

    In situ thermomechanical experiments are planned as part of the Yucca Mountain Site Characterization Project that require instruments to measure stress and displacement at temperatures that exceed the typical specifications of existing geotechnical instruments. A high degree of instrument reliability will also be required to satisfy the objectives of the experiments, therefore a study was undertaken to identify areas where improvement in instrument performance was required. A preliminary list of instruments required for the experiments was developed, based on existing test planning and analysis. Projected temperature requirements were compared to specifications of existing instruments to identify instrumentation development needs. Different instrument technologies, not currently employed in geotechnical instrumentation, were reviewed to identify potential improvements of existing designs for the high temperature environment. Technologies with strong potentials to improve instrument performance with relatively high reliability include graphite fiber composite materials, fiber optics, and video imagery

    It is necessary that development requirements, techniques to be developed, and development tasks and approach are established to develop the SMART instrumentation system. It is important to establish the development strategies for input for developing SMART instrumentation system. To meet above needs, the industry general and nuclear instrumentation techniques were analyzed and reviewed, respectively, based on the classification of instrumentation to analyze the industrial instrumentation techniques, and analysis results which described the inherent merits and demerits of each technique can be used for inputs to select the instruments for SMART. For the instrumentation techniques for nuclear environments, the major instrumentation techniques were reviewed, and the instrumentation system were established. The following development approaches were established based on the development requirements and the analysis results of research and development trends of industrial and nuclear instrumentation techniques.

  15. The history of thoracic surgical instruments and instrumentation.

    2000-02-01

    Thoracic surgical practice has evolved from the innovations of its pioneers. Beginning with the stethoscope discovered by Laënnec with his system of auscultation, to the tools we use in the dissection and control of the hilum of the lung for resection, our practice of thoracic surgery has been entwined with the development of instruments and instrumentation. The development of strategies to prevent death from the open pneumothorax began with manual control of the mediastinum and progressed through differential pressure to, finally, the technique of intubation and the methods of positive-pressure and insufflation anesthesia. The instruments we place in our hands are not enough to define our art. Entry into the chest would not be possible without the use of rib retractors, rib shears, and even periosteal elevators. Finally, to the present day of minimally invasive techniques and the application of thoracoscopy for therapeutic purposes, we find the efforts of our predecessors well developed. For the progression from the fear of the open pneumothorax to the present-day state of the ease of thoracotomy for lung resection we are indebted to those who gave so much of their time and, for some, their lives to death from tuberculosis, to allow the advancement of our practice of surgery. These great people should be remembered not only for their acceptance of novel ideas but also, more importantly, for their lack of fear of testing them.

    2003-08-01

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

    2005-01-01

    When research and test reactors wish to further understand the Fuel Elements behavior when operating as well as mastering their irradiation conditions, operators carry out neutron and thermo hydraulic analysis. For thermal calculation, the codes used have to be preliminary validated, at least in the range of the reactor safety operational limits. When some further investigations are requested either by safety authorities or for its own reactor needs, instrumented tools are the ultimate solution for providing representative measurements. Such measurements can be conducted for validating thermal calculation codes, at nominal operating condition as well as during transients ones, or for providing numerous and useful data in the frame of a new products qualification program. CERCA, with many years of experience for implanting thermocouples in various products design, states in this poster his manufacturing background on instrumented elements, plates or targets. (author)

Nuclear instrumentation has evolved greatly since the discovery of radioactivity. There has been tremendous advancement in detector technology, electronics, computer technology, and development of efficient algorithms and methods for spectral processing to extract precisely qualitative and quantitative information of the radiation. Various types of detectors and nuclear instruments are presently available and are used for different applications. This paper describes nuclear radiation, its detection and measurement and associated electronics, spectral information extraction, and advances in these fields. The paper also describes challenges in this field

    We have built new general purpose cards for data acquisition taking advantage of recent developments in electronics. At the end of the year, most scheduled instruments at the ILL will be running under UNIX with VME electronics front-end. As the VME electronics of the ILL was designed at the beginning of the eighties, the instrument control section (SCI) at ILL has prepared a renewal plan for two reasons: - first, all the processor cards of the Institute are based on MIZAR processor boards and MIZAR stopped the production of this card last year, as the market was shrinking; - in addition, processors and programmable electronics are now 10 times faster. The electronics services want to take full advantage of these new performances. (author)

    2005-01-01

    A framework for quantitatively evaluating current and proposed gamma-ray search instrument designs has been developed. The framework is designed to generate a large library of ''virtual neighborhoods'' that can be used to test and evaluate nearly any gamma-ray sensor type. Calculating nuisance-source emissions and combining various sources to create a large number of random virtual scenes places a significant computational burden on the development of the framework. To reduce this burden, a number of radiation transport simplifications have been made which maintain the essential physics ingredients for the quantitative assessment of search instruments while significantly reducing computational times. The various components of the framework, from the simulation and benchmarking of nuisance source emissions to the computational engine for generating the gigabytes of simulated search scenes, are discussed

    The paper proposes an audio indication method for presenting to a pilot the information regarding the relative positions of an aircraft in the tasks of precision piloting. The implementation of the method is presented, the use of such parameters of audio signal as loudness, frequency and modulation are discussed. To confirm the operability of the audio indication channel the experiments using modern aircraft simulation facility were carried out. The simulated performed the instrument landing using the proposed audio method to indicate the aircraft deviations in relation to the slide path. The results proved compatible with the simulated instrumental landings using the traditional glidescope pointers. It inspires to develop the method in order to solve other precision piloting tasks.

    Instrumentation required for uranium exploration may be broadly classified based on surface and sub-surface measurement of gamma-ray intensity. Surface measurement of gross and spectral gamma intensity are carried out by employing portable Geiger Mueller/scintillation counters and four-channel spectrometers. Measurement of thoron ( 220 Rn) and radon ( 222 Rn) in the soil gas is being carried out by closed circuit technique using radon measuring system. Radiometric mapping of trenches, pits and mine-faces are carried out using shielded probe with 2π source geometry, whereas logging sonde with instruments through the steel armoured cable are employed for point to 4π geometry. Spectral borehole logging system with built-in multi-channel analyser (MCA) has been developed for the uranium exploration programme for AMD. Note-book PC based high sensitivity air-borne gamma-ray spectrometric survey system has been designed, developed and test flown. (author)

    The advent of pulsed neutron sources makes available high epithermal neutron fluxes (in the energy range between 500 meV and 100 eV). New dedicated instrumentation, such as Resonance Detectors, was developed at ISIS spallation neutron source in the last years to apply the specific properties of this kind of neutron beam to the study of condensed matter. New detection strategies like Filter Difference method and Foil Cycling Technique were also developed in parallel to the detector improvement at the VESUVIO beamline. Recently, epithermal neutron beams were also used at the INES beamline to study elemental and isotopic composition of materials, with special application to cultural heritage studies. In this paper we review a series of epithermal neutron instrumentation developed at ISIS, their evolution over time and main results obtained

    Ursic, Rok; Solar, Borut

    2004-01-01

    Being user friendly should be the main guidance, beside the self-understood high performance, in today's instrumentation development. Here we identify three components of the user-friendly policy: the all-in-one concept, customization, and connectivity. All-in-one is the concept of unification of various building blocks and thus various functionalities in one product. The customization is enabled by the product's reconfigurability that allows a product to grow and support new requirements and applications without changing hardware. The consequence of the two is the capacity of the single instrument to perform a variety of tasks that before were split among different devices. The last of the three is connectivity that improves the relationship between controls and beam diagnostics, brings out-of-the-crate freedom, and opens unforeseen possibilities for intra-accelerator cooperation and remote technical support

Nessa perspectiva, o gerenciamento da informação passou a ser uma atividade imprescindível para as organizações, ou seja, prospectar e monitorar informações que propiciem decisões e ações estratégicas, de maneira a propiciar diferenciais competitivos organizacionais. As condições de acesso e busca para a apropriação e uso de informações no contexto organizacional tornou-se uma atividade complexa devido à subjetividade da informação, característica esta que impõe ao gestor da informação desenvolver uma percepção aguçada no que tange ao mundo informacional, de maneira a atender as necessidades e demandas informacionais eficazmente.

  17. High resolution tomographic instrument development

    International Nuclear Information System (INIS)

    1992-01-01

    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

  20. Peer Learning in Instrumental Practicing

    Nielsen, Siw G.; Johansen, Guro G.; Jørgensen, Harald

    2018-01-01

    In higher music education (HME), the notion of “private teaching, private learning” has a long tradition, where the learning part rests on the student's individual practicing between instrumental lessons. However, recent research suggests that collaborative learning among peers is beneficial in several aspects, such as sense of belonging, motivation and self-efficacy. This is consistent with the concept of vicarious learning. In this study, we conducted a survey among bachelor music students in church music, performance or music education programs enrolled in a music academy (N = 96), where parts of the questionnaire addressed peer learning and peer's influence on the students's instrumental practicing, and the degree of satisfaction with their practicing. These issues were seen in relation to gender, musical genre and study program. Overall, the students reported engaging in peer learning related to their instrumental practicing, to various degrees. This involved discussing practicing matters with peers, and practicing together with peers. However, student's reports of their views on peer learning, show that they perceive it more beneficial than the amount of time reported doing it would indicate. No significant gender differences were found, but students within improvised music/jazz engaged the most in peer learning, and church music students the least. Neither the degree of engaging in peer learning nor reported influence from peers correlated significantly with the degree of satisfaction. We discuss whether a general dissatisfaction is caused by being in a competitive learning environment combined with a privatized culture for learning. Finally, we suggest that collaborative forums for instrumental practicing within HME institutions can function as constructive and supportive arenas to enhance students learning and inner motivation.

    In higher music education (HME), the notion of "private teaching, private learning" has a long tradition, where the learning part rests on the student's individual practicing between instrumental lessons. However, recent research suggests that collaborative learning among peers is beneficial in several aspects, such as sense of belonging, motivation and self-efficacy.

    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.

    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.

  10. Geotechnical instrumentation for repository shafts

    International Nuclear Information System (INIS)

    Lentell, R.L.; Byrne, J.

    1993-01-01

    The US Congress passed the Nuclear Waste Policy Act in 1980, which required that three distinctly different geologic media be investigated as potential candidate sites for the permanent disposal of high-level nuclear waste. The three media that were selected for study were basalt (WA), salt (TX, LA, MS, UT), and tuff (NV). Preliminary Exploratory Shaft Facilities (ESF) designs were prepared for seven candidate salt sites, including bedded and domal salt environments. A bedded-salt site was selected in Deaf Smith County, TX for detailed site characterization studies and ESF Final Design. Although Congress terminated the Salt Repository Program in 1988, Final Design for the Deaf Smith ESF was completed, and much of the design rationale can be applied to subsequent deep repository shafts. This paper presents the rationale for the geotechnical instrumentation that was designed for construction and operational performance monitoring of the deep shafts of the in-situ test facility. The instrumentation design described herein can be used as a general framework in designing subsequent instrumentation programs for future high-level nuclear waste repository shafts

    The author has been engaged in the development of fast reactors over the last 30 years with both an involvement with the early technology development on the experimental breeder reactor Joyo, and latterly continuing this work on the prototype breeder reactor, Monju. In order to pass on this experience to younger engineers this paper is produced to outline this experience in the sincere hope that the information given will be utilised in future educational training material. The paper discusses the wide diversity on the associated instrument technology which the fast breeder reactor requires. The first chapter outlines the fast reactor system, followed by discussions on reactor instrumentation, measurement principles, temperature dependencies, and verification response characteristics from various viewpoints, are discussed in chapters two and three. The important issues of failed fuel location detection, and sodium leak detection from steam generators are discussed in chapters 4 and 5 respectively. Appended to this report is an explanation on the methods of measuring response characteristics on instrumentation systems using error analysis, random signal theory and measuring method of response characteristic by AR (autoregressive) model on which it appears is becoming an indispensable problem for persons involved with this technology in the future.

  12. Measuring instruments of corporate reputation

    2008-12-01

    Full Text Available The subject of this paper is focused on the instruments for the measurement of corporate reputation. Recent research of the elements which influence the success of a company shows a growing interest in intangible values. 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.

    Directory of Open Access Journals (Sweden)

    Grün Roberto

    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.

  18. Multimodality instrument for tissue characterization

    Science.gov (United States)

    Mah, Robert W. (Inventor); Andrews, Russell J. (Inventor)

    2004-01-01

    A system with multimodality instrument for tissue identification includes a computer-controlled motor driven heuristic probe with a multisensory tip. For neurosurgical applications, the instrument is mounted on a stereotactic frame for the probe to penetrate the brain in a precisely controlled fashion. The resistance of the brain tissue being penetrated is continually monitored by a miniaturized strain gauge attached to the probe tip. Other modality sensors may be mounted near the probe tip to provide real-time tissue characterizations and the ability to detect the proximity of blood vessels, thus eliminating errors normally associated with registration of pre-operative scans, tissue swelling, elastic tissue deformation, human judgement, etc., and rendering surgical procedures safer, more accurate, and efficient. A neural network program adaptively learns the information on resistance and other characteristic features of normal brain tissue during the surgery and provides near real-time modeling. A fuzzy logic interface to the neural network program incorporates expert medical knowledge in the learning process. Identification of abnormal brain tissue is determined by the detection of change and comparison with previously learned models of abnormal brain tissues. The operation of the instrument is controlled through a user friendly graphical interface. Patient data is presented in a 3D stereographics display. Acoustic feedback of selected information may optionally be provided. Upon detection of the close proximity to blood vessels or abnormal brain tissue, the computer-controlled motor immediately stops probe penetration. The use of this system will make surgical procedures safer, more accurate, and more efficient. Other applications of this system include the detection, prognosis and treatment of breast cancer, prostate cancer, spinal diseases, and use in general exploratory surgery.

    Emerging technologies in the field of ''Test ampersand Measurement'' have recently enabled the development of the Rapidly Adaptable Instrumentation Tester (RAIT). Based on software developed with LabVIEW, the RAIT design enables quick reconfiguration to test and calibrate a wide variety of telemetry systems. The consequences of inadequate testing could be devastating if a telemetry system were to fail during an expensive flight mission. Supporting both open-bench testing as well as automated test sequences, the RAIT has significantly lowered total time required to test and calibrate a system. This has resulted in an overall lower per unit testing cost than has been achievable in the past

    International Nuclear Information System (INIS)

    Kessler, F. M.; Connell, T. J.; Ryan, M. P.

    1992-01-01

    I and C upgrades are comprised of a varying range of content, complexity, expansiveness, and criticality. There are common threads in all upgrades which can be simplified by the development of a long term I and C upgrade plan. The development of a such a plan can establish effective ground rules for upgrades, large and small. It can be the basis from which to begin an upgrade evaluation and the standard which is used to compare the degree of compliance of any upgrade regarding the plan or to define the differences from the plan and an individual upgrade. Primary motivation for I and C upgrades are obsolescence and unavailability of spare parts. Numerous other areas of consideration are also involved in an upgrade. Today's technology results in most upgrades largely or totally utilizing digital equipment. The use of digital equipment is fairly new in many I and C applications and requires an elaborate evaluation from functional, qualification, operational, and licensing perspectives as well as others. A well defined upgrade plan developed as a basis for I and C upgrades is a significant start to ensuring an effective upgrade process. Properly developed and implemented, the plan will support I and C upgrade efforts to ensure that the intricacies associated with such tasks eliminate the existing problems which require the upgrade to be performed. The upgrade plan also results in ensuring the maximum benefit from all perspectives of the plant enhancements being carried out and considered for future implementation. Instrumentation and controls aging and replacement are issues of growing importance due to the potential for significant impact on plant operation and efficiency. Obsolescence and unavailability of spare parts are major drivers towards evaluating the cost benefits of upgrading current equipment. In addition to these two primary factors, the advantages of utilizing digital equipment have also become of prime importance when evaluating instrumentation and

    International Nuclear Information System (INIS)

    Wakayama, N.; Ara, K.; Terada, H.; Yamagishi, H.; Tomoda, T.

    1982-06-01

    This paper describes developmental works on the instrumentation of the Experimental VHTR. In the area of the nuclear instrumentation for the reactor control, high temperature fission counter-chambers have been developed. These withstood the accelerated irradiation life tests at 600 deg. C, the long term in-reactor operating test at 600 deg. C and the 800 deg. C-operating tests for several hundred hours in a simulated accident condition. Platinum-Molybdenum alloy thermocouples have been studied as a neutron-irradiation-resistant high-temperature thermocouple for the in-core temperature distribution monitoring of the VHTR in the temperature range between 1000 deg. C and 1350 deg. C. The instability problems of the Pt-5% Mo/Pt-0.1% Mo thermocouple seem to be overcome by introducing a double sheath structure and adopting a better material to the inner sheath. A local failure and abnormality monitoring method for the HTR fuel is also studied using a gas-sweeping irradiation rig for the CPF compacts. This study aims mainly at the development of a method to compensate for the dependency of the FP-release rate on the fuel temperature, the neutron flux density, the burn-up and others, in order to increase the detection sensitivity of fuel failures.

  15. Economic instruments for waste management

    International Nuclear Information System (INIS)

    Malaman, R.

    1991-01-01

    Economic instruments for the implementation of environmental policies distinguish themselves from traditional tools (the 'command and control' type) for the reason that: they influence the costs and the benefits of the economic agents in question; they change the behaviour of the subjects in question in a way that they guarantee behaviour trends less harmful to the environment; they guarantee the assignment of adequate prices to the natural resources that traditionally don't have a price and therefore are consumed excessively by the economic subjects; normally they impose the transfer of economic resources to the disadvantage of the subjects responsible for the phenomena of pollution; certain objective pollution reduction data guarantee the minimization of the social costs of pollution abatement, that is, of the total costs on the economic system in general (economists define this characteristic as the 'static efficiency'); they guarantee what is called in economical jargon, the dynamic efficiency, i.e., in practice, they determine a continuous incentive for the reduction of the emission of the various pollutants and for the realization of the technological innovations that are able to control the pollution; they are more flexible than the instruments of direct regulation, because they leave the subjects a freedom of choice under different price conditions than in the past; they are flexible as well for the reason that the public operator can intervene rapidly to change the way of application

    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 −3

  18. Instrument for measuring flow velocities

    International Nuclear Information System (INIS)

    Griffo, J.

    1977-01-01

    The design described here means to produce a 'more satisfying instrument with less cost' than comparable instruments known up to now. Instead of one single turbine rotor, two similar ones but with opposite blade inclination and sense of rotation are to be used. A cylindrical measuring body is carrying in its axis two bearing blocks whose shape is offering little flow resistance. On the shaft, supported by them, the two rotors run in opposite direction a relatively small axial distance apart. The speed of each rotor is picked up as pulse recurrence frequency by a transmitter and fed to an electronic measuring unit. Measuring errors as they are caused for single rotors by turbulent flow, profile distortion of the velocity, or viscous flow are to be eliminated by means of the contrarotating turbines and the subsequently added electronic unit, because in these cases the adulterating increase of the angular velocity of one rotor is compensated by a corresponding deceleration of the other rotor. The mean value then indicated by the electronic unit has high accurancy of measurement. (RW) [de

    The dual feed astrometric instrument software of PRIMA (PACMAN) that is currently being integrated at the VLTI will use two spatially modulated fringe sensor units and a laser metrology system to carry out differential astrometry. Its software and hardware compromises a distributed system involving many real time computers and workstations operating in a synchronized manner. Its architecture has been designed to allow the construction of efficient and flexible calibration and observation procedures. In parallel, a novel scheme of integrating M-code (MATLAB/OCTAVE) with standard VLT (Very Large Telescope) control software applications had to be devised in order to support numerically intensive operations and to have the capacity of adapting to fast varying strategies and algorithms. This paper presents the instrument software, including the current operational sequences for the laboratory calibration and sky calibration. Finally, a detailed description of the algorithms with their implementation, both under M and C code, are shown together with a comparative analysis of their performance and maintainability.

  20. Tamper indicating radiation surveillance instrumentation

    International Nuclear Information System (INIS)

    Chambers, W.H.; Ney, J.F.

    1975-01-01

    Prototype personnel and shipping dock portal monitors suitable for unattended use were fabricated and tested. The requirement for continuous operation with only periodic inspection along with a desire for minimum costs and minimum interference with normal plant operation imposed unique design constraints. The design, operation, and performance of the detection and data recording instrumentation are described, as well as the tamper indicating techniques required to protect the collected data. The essential elements of either of the two instruments include a gamma detector array, signal conditioning electronics, digital alarm logic circuitry, power supplies, a microwave occupancy monitor, surveillance camera, irreversible electromechanical counters, and the appropriate tamper indicating envelope protecting these elements. Attempts to penetrate the tamper indicating envelope require material removal, and undetectable repair is very difficult, if not impossible. The techniques for joining major subassemblies and providing unique seals are also described. The personnel doorway uses a double pole array of NaI(Tl) detectors, and outputs are taken from a single channel pulse height analyzer with a window set at 60 to 250 keV and the lower level discriminator at greater than 60 keV. A sliding interval counter is used to make comparisons to an accumulated background at the 4sigma level. Logic design, sensitivity for special nuclear materials, false alarm data, and test procedures are described in detail. The shipping dock monitor had different design constraints and therefore uses a single, long, cylindrical plastic scintillator. Some differences in signal conditioning and processing are also described. (auth)

  1. Instrumentation for mass spectrometry: 1997

    Energy Technology Data Exchange (ETDEWEB)

    McLuckey, S.A.

    1997-08-01

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

    Full Text Available Este trabalho tem como objetivo analisar dois tipos de abordagem – tradicional e alternativa – utilizadas nos estudos de usuário. Para isso, adotou-se os instrumentos de coleta de dados adequados a cada tipo de abordagem: o questionário, na abordagem tradicional, e a entrevista, na abordagem alternativa. Percebeu-se que o primeiro não permite estabelecer um diálogo mais estreito com o usuário, devido à limitação das respostas, uma vez que já estavam definidas. Já a entrevista possibilitou conhecer com mais detalhes as necessidades informacionais de cada usuário e como se efetiva seu processo de busca e uso. Assim, verificou-se através de quais portais eletrônicos os usuários buscam essa informação, procurando entender se esses portais são os mesmos que possuem vinculados os provedores de seus e-mails, visto que esses portais eletrônicos deveriam possibilitar também o suprimento de suas necessidades informacionais. Concluiu-se que a maioria dos sujeitos desta pesquisa não utiliza, por diversos motivos, seus provedores de e-mail principal para buscar informação. A partir dos resultados, observou-se que a primeira abordagem não reconhece as necessidades individuais de cada usuário, limitando-se à objetividade de um tratamento estatístico. Em contrapartida, a segunda abordagem reconhece a subjetividade e as necessidades desses usuários.

    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.

    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.

    For several years Los Alamos has incorporated microprocessors into instruments to expand the capability of portable survey type equipment. Beginning with portable pulse height analyzers, the developments have expanded to small dedicated instruments which handle the measurement and interpretation of various radiation fields. So far, instruments to measure gamma rays, neutrons, and beta particles have been produced. The computer capability built into these instruments provides significant computational power into the instruments. Capability unheard of a few years ago in small portable instruments is routine today. Large computer-based laboratory measurement systems which required much space and electrical power can now be incorporated in a portable hand-held instrument. The microprocessor developments at Los Alamos are now restricted to radiation monitoring equipment but can be expanded to chemical and biological applications as well. Applications for radiation monitoring equipment and others are discussed

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

    1989-01-01

    The present invention concerns a nuclear reactor instrumentation power monitor that can be used in, for example, BWR type nuclear power plants. Signals from multi-channel detectors disposed on field units are converted respectively by LPRM signal circuits. Then, the converted signals are further converted by a multiplexer into digital signals and transmitted as serial data to a central monitor unit. The thus transmitted serial data are converted into parallel data in the signal processing section of the central monitor unit. Then, LPRM signals are taken out from each of channel detectors to conduct mathematical processing such as trip judgment or averaging. Accordingly, the field unit and the central monitor unit can be connected by way of only one data transmission cable thereby enabling to reduce the number of cables. Further, since the data are transmitted on digital form, it less undergoes effect of noises. (I.S.)

All patients kept the diary...... for one to eight months. The clinical and diary diagnosis of migraine with and without aura was the same in, respectively, 72 and 87% of the patients. Nausea, photophobia and phonophobia tended to be more pronounced at the clinical interview. The diary identified 20 more cases of episodic tension......-type headache and 15 fewer cases of chronic tension-type headache than the clinical interview. Two blinded observers always made the same IHS diagnoses when interpreting the diagnostic headache diary. A combination of a clinical interview and the diagnostic headache diary gives a qualitatively...

    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. Results on the performance of these major components are summarised. (orig.)

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

  10. Online Personalization of Hearing Instruments

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

    The 6-meter Atacama Cosmology Telescope (ACT) is making detailed maps of the Cosmic Microwave Background at Cerro Toco in northern Chile. In this talk, I focus on the design and operation of the telescope and its commissioning instrument, the Millimeter Bolometer Array Camera. The camera contains three independent sets of optics that operate at 148 GHz, 217 GHz, and 277 GHz with arcminute resolution, each of which couples to a 1024-element array of Transition Edge Sensor (TES) bolometers. I will report on the camera performance, including the beam patterns, optical efficiencies, and detector sensitivities. Under development for ACT is a new polarimeter based on feedhorn-coupled TES devices that have improved sensitivity and are planned to operate at 0.1 K.

    The Electric Power Research Institute has developed instruments capable of verifying time responses of power plant pressure sensors and temperature sensors. A patent is pending on the pressure-sensor device, and the temperature-sensor device is already commercially available. The devices, EPRI's first hardware products to be marketed, are the result of research to find technological solutions to the problems of knowing the time period when temperature and pressure changes occur in light water reactors. The hydraulic pressure-sensor device is a portable unit that can conveniently test equipment in place. Utilities can obtain detailed information from EPRI's project report to construct their own. The loop current step response (LCSR), measuring resistance temperature, is also a compact system suitable for in-plant testing

    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.

  18. Hybrid microcircuits for nuclear instrumentation

    Kulkarni, R.G.

    2005-01-01

    Hybrid microcircuits (HMCs) have distinct advantages over their rival products like printed circuit boards (PCBs) and integrated circuits (ICs), and are able to survive the onslaught of Moore's law, by retaining the niche market for themselves. The ASIC development cost is normally huge and when the volumes are small (less than ten thousand or so), the prohibitively high unit cost deters the potential customers. However the HMCs can be developed at a small fraction of an ASIC development cost and thus they are attractive when the volumes are small, as in the case of professional electronics industries like defense, broadcast, or instrumentation industries. The hybrid microcircuit (HMC) technology can involve one of the two processes: thick-film and thin- film. Broadly the thick-film process consists of printing and firing of, conductor and resistor pastes, on an Alumina substrate. The thin-film process consists of photo lithographic etching of, conductor and resistor patterns, on a metal/resistor sputtered high purity Alumina substrate. The active devices, either in die-form or in surface-mount form, are attached to the thick-film or the thin-film substrate. The passive devices like chip inductors and chip capacitors are also attached to the substrate. This paper discusses in detail the thick-film and the thin-film processes and their relative merits and demerits. The associated qualification and screening procedures followed to provide reliable HMCs to the customer are described. The existing HMC facilities and the product range available in Bharat Electronics including the HMCs developed for nuclear instrumentation are presented. (author)

Para realizar o cuidado domiciliar nos sistemas de saúde, principalmente na perspectiva do serviço público, devem ser considerados alguns aspectos referentes à organização e à formação dos profissionais de saúde. O sucesso do cuidado domiciliar está em olhar o indivíduo e sua família em seu contexto, visualizando e considerando seu meio social, suas inserções, seu local de moradia, seus hábitos e relações e qualquer outra coisa ou situação que façam parte de seu existir e estar no mundo. Autonomia, para os indivíduos e familiares terem condições para desenvolverem o cuidado no domicílio numa situação de adoecimento, é a possibilidade de estar capacitado a realizar o cuidado com ajuda do sistema de saúde, com profissionais que ensinem, orientem e acompanhem e principalmente com uma enfermeira que tenha sensibilidade e capacidade técnica-científica para estabelecer metas de cuidado factíveis à realidade de saúde-doença vivenciada.The objective of this essay is to reflect on the possibility of searching for individual and family's autonomy in public health services through health professionals, mainly nurses in the development of home care.

    Electromagnetic flow meters, level gauges and differential pressure gauges are among the main measurement instruments designed and tested at the Commissariat a l'Energie Atomique (CEA) for sodium reactors. The main characteristics of the flow meters used with RAPSODIE are indicated. The instruments used in this connection are of the permanent -magnet or electromagnet type (in the primary circuits). A description is given of the calibration methods employed - use is made of diaphragms or Venturi tubes as standard flow meters - and information is given on the results measured for maximum sodium flows of 400 m{sup 3}/h. Three types of continuous level gauge have been studied. Resistance gauge. Two varieties used for the 1 - and 10-MW test circuits of RAPSODIE are described. In one there is a compensation resistance along the whole height of the measuring element (the continuous gauges used with the RAPSODIE reactor are at present of this type). In the other type of gauge a device is incorporated to heat the measurement element and prevent the formation of conducting deposits (prototype sodium tests have been completed). Induction gauge. This type has two coupled coils and is fitted with a device to compensate for temperature effects. A description is given of a prototype which has been built and the results obtained in the course of sodium tests are described. Ultrasonic gauge. With this type, a transmitter is fitted on top of the outside of the sodium container; there is also a vertical wave guide, the bottom of which is immersed in the liquid metal and possesses a reflector system which returns the ultrasonic beam towards the surface. Fixed reference marks provide a permanent means of calibration and the whole apparatus is welded. This type of gauge is now being constructed. The differential pressure gauges that have been built, and used in particular with Venturi tube flow meters, are modified versions of the devices employed with the 1 - and 10-MW test circuits of

    In the last 15 years the CEGB has experienced progressive plant development, integration and changes in operating regime through nine nuclear (gas-cooled reactor) power stations with corresponding instrumentation advances leading towards more refined centralized control. Operation and reliability experience with reactor instrumentation is reported in this paper with reference to the progressive changes related to the early magnox, late magnox and AGR periods. Data on instrumentation reliability in terms of reactor forced outages are presented and show that the instrumentation contributions to loss of generating plant availability are small. Reactor safety circuits, neutron flux and temperature measurements, gas analysis and vibration monitoring are discussed. In reviewing the reactor instrumentation the emphasis is on reporting recent experience, particularly on AGR equipment, but overall performance and changes to magnox equipment are included so that some appreciation can be obtained of instrumentation requirements with respect to plant lifetimes.

    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.

    The vigor with which a participant performs actions that produce valuable outcomes is subject to a complex set of motivational influences. Many of these are believed to involve the amygdala and the nucleus accumbens, which act as an interface between limbic and motor systems. One prominent class of influences is called pavlovian-instrumental transfer (PIT), in which the motivational characteristics of a predictor influence the vigor of an action with respect to which it is formally completely independent. We provide a demonstration of behavioral PIT in humans, with an audiovisual predictor of the noncontingent delivery of money inducing participants to perform more avidly an action involving squeezing a handgrip to earn money. Furthermore, using functional magnetic resonance imaging, we show that this enhanced motivation was associated with a trial-by-trial correlation with the blood oxygenation level-dependent (BOLD) signal in the nucleus accumbens and a subject-by-subject correlation with the BOLD signal in the amygdala. Our data dovetails well with the animal literature and sheds light on the neural control of vigor.

    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.)

    Guzman, Felipe

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

  11. Internal communication: challenges and instruments

    Mike Hughes, the publisher for Publicity Express once said that 'Without Public Relations a terrible thing happens: nothing'. The term 'Public Relations' describes the efficient and coherent organization of external and internal communication. A company has an external public and an internal one as well. The employees of an organization are important carriers of the message the organization wants to transmit, but moreover, they are the driving engine behind the success of an enterprise. Better informed employees are more confident and prepared to get involved in challenging tasks such as obtaining public support for nuclear power. Internal communication is the continuous flux of information on all hierarchic levels both horizontally and vertically. The efficient usage of internal communication tools brings great advantages and benefits for the managers and the personnel of an organization. Despite this, organizing an integrated internal communication strategy is a challenging effort for any PR department. The paper deals with the instruments of internal communication, the obstacles usually encountered and the possibilities to apply an integrated strategy in large companies operating in the nuclear field.

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

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

    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.

  16. European Languages: Instruments and Symbols

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

    Scientific investigations involving the use of neutron beams have been centered at reactor sources for the last 35 years. Recently, there has been considerable interest in using the neutrons produced by accelerator driven (pulsed) sources. Such installations are in operation in England, Japan, and the United States. In this article a brief survey is given of how the neutron beams are produced and how they can be optimized for neutron scattering experiments. A detailed description is then given of the various types of instruments that have been, or are planned, at pulsed sources. Numerous examples of the scientific results that are emerging are given. An attempt is made throughout the article to compare the scientific opportunities at pulsed sources with the proven performance of reactor installations, and some familiarity with the latter and the general field of neutron scattering is assumed. New areas are being opened up by pulsed sources, particularly with the intense epithermal neutron beams, which promise to be several orders of magnitude more intense than can be obtained from a thermal reactor

    The Stratospheric Wind Interferometer for Transport studies (SWIFT) instrument is a proposed limb-viewing satellite instrument that employs the method of Doppler Michelson interferometry to measure stratospheric wind velocities and ozone densities in the altitude range of 15–45 km. The values of the main instrument parameters including filter system parameters and Michelson interferometer parameters are derived using simulations and analyses. The system design requirements for the instrument and spacecraft are presented and discussed. Some of the retrieval-imposed design requirements are also discussed. Critical design issues are identified. The design optimization process is described. The sensitivity of wind measurements to instrument characteristics is investigated including the impact on critical design issues. Using sensitivity analyses, the instrument parameters were iteratively optimized in order to meet the science objectives. It is shown that wind measurements are sensitive to the thermal sensitivity of the instrument components, especially the narrow filter and the Michelson interferometer. The optimized values of the main system parameters including Michelson interferometer optical path difference, instrument visibility, instrument responsivity and knowledge of spacecraft velocity are reported. This work also shows that the filter thermal drift and the Michelson thermal drift are two main technical risks. (paper)

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

    Amici, J-M

    2014-12-01

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

    Terrestrial gamma-ray flashes (TGFs) are brief MeV gamma-ray flashes that are associated with thunderstorms, around 12km in altitude, and are viewed by orbiting satellites. These bright flashes of high energy photons were discovered in 1994. The two major models for TGFs that originate in thunderstorms are the Lightning Leader and Relativistic Feedback Discharge (RFD) model. Both depend on energetic electrons radiating via bremsstrahlung emission. The Lightning Leader model theorizes that lightning step leaders can accelerate electrons to relativistic speeds. The RFD model states that an energetic seed particle can be accelerated to relativistic speeds by strong electric fields inside of a thunderstorm. The main difference in the results of the two models is as follows; the Lightning Leader model results in a wider beam of gamma-rays than the RFD model because the electric field of a thunderstorm is more structured than that of lightning. The TRYAD mission will be the first to fly two detectors, inside CubeSats, in formation to detect TGFs from multiple points in the sky. The data from the CubeSats and the World Wide Lightning Location Network (WWLLN) will likely provide enough insight to constrain or eliminate some of the existing models for TGFs.This summer was spent testing components and constructing the engineering model of the scientific instrument that will be used to detect TGFs. The detector is made up of four lead-doped plastic scintillators which are coupled to arrays of Silicon Photomultipliers (SiPM). The signal from the SiPM array is then fed into a discriminator where a lower energy estimate can be determined and photon counts are recorded. I will present the progress made over the summer constructing the engineering model.

    When two instruments, both having replicated measurements, are used to measure the same set of items, between instrument information may be used to augment the within instrument precision estimate. A method is presented which combines the within and between instrument information to obtain an unbiased and minimum variance estimate of instrument precision. The method does not assume the instruments have equal precision

  3. Vision though afocal instruments: generalized magnification and eye-instrument interaction

    Science.gov (United States)

    Harris, William F.; Evans, Tanya

    2018-04-01

    In Gaussian optics all observers experience the same magnification, the instrument's angular magnification, when viewing distant objects though a telescope or other afocal instruments. However, analysis in linear optics shows that this is not necessarily so in the presence of astigmatism. Because astigmatism may distort and rotate images it is appropriate to work with generalized angular magnification represented by a 2 × 2 matrix. An expression is derived for the generalized magnification for an arbitrary eye looking through an arbitrary afocal instrument. With afocal instruments containing astigmatic refracting elements not all eyes experience the same generalized magnification; there is interaction between eye and instrument. Eye-instrument interaction may change as the instrument is rotated about its longitudinal axis, there being no interaction in particular orientations. A simple numerical example is given. For sake of completeness, expressions for generalized magnification are also presented in the case of instruments that are not afocal and objects that are not distant.

  1. Health physics instrumentation - a progress report

    International Nuclear Information System (INIS)

    Maushart, R.

    1992-01-01

    Health Physics Instruments have changed rather dramatically in the past decade. On the one hand, technological innovations like Microprocessors, data storage facilities and imaging displays have altered shape, size and appearance of the classical devices, particularly the hand-held ones. On the other hand, instruments are increasingly being considered as an integral part of Radiation Protection procedures and organizations, supporting a smooth and reliable implementation of all necessary measures. This implies ease of operation, and extensive self-checking and performance control features. Since there are different categories of users with quite different degrees of motivation and training, the measuring instruments of the future will have to be adapted to specific types of users. Instruments for 'professional' radiation protection - for example in nuclear power plants and nuclear technology - will differ from instruments used in the radionuclide laboratory, where radiation protection will necessarily have to be done as a 'side-job'.

  2. Technological considerations in emergency instrument preparedness

    International Nuclear Information System (INIS)

    Selby, J.M.

    1976-01-01

    Emergency preparedness has been emphasized during the development of the nuclear industry. Existing instrumentation technology has been effectively applied to minimizing the probability of accidents. Radiological instrumentation provided for the measurement of ambient radiation levels or routine releases of radioactive material is usually adequate to provide an early warning that an accident is occurring. In contrast, radiological instrumentation capable of providing a reasonable measure of the source term which could be involved in a severe accident has not received enough attention. In emergency planning the capability should be established for identifying as promptly as possible the need for evasive action out in the plant environs and for minimizing the consequences of an accident in terms of resultant human exposure. Therefore instrumentation is required to measure the source term no matter where the point of release might be, together with instrumentation for obtaining meteorological data sufficient to establish the path of the release in the environment

    Object: To permit satisfactory output measurement by preventing the bending of a in-core instrument tube within a reactor due to vibrations by means of a spring and thereby preventing mechanical damage of an adjacent fuel channel box. Structure: At a corner of a channel box of a fuel assembly, a in-core instrument tube is arranged along a channel box and has its surface provided with a plurality of removable leaf springs arranged in the direction of axis of the in-core instrument tube and each having an arcular tip. Thus, when the in-core instrument tube is inserted into the reactor, the arcular tip portions of the leaf springs are brought into plane contact with the corner of the channel box so that the in-core instrument tube is elastically supported on the channel box. Thus, there is no possibility of causing damage to the adjacent fuel channel box. (Kamimura, M.)

    Full Text Available Instruments of promotion as a part of marketing mix are usually associated with companies but more and more countries use this instrument in order to boost their exports. These foreign trade promotion instruments are now popular in many countries in the world since their use is not opposed to any World Trade Organization rules. Marketing instruments of trade promotions are the most important. They include National Exhibitions and National labels of origin and quality. In order to coordinate the application of these instruments countries have established national bodies for trade promotion. Many studies in the past had argued that national Agencies established to promote export did not had any real success, but recent studies indicate that they could have a significant impact on country export promotion. The result of this rise in impact of national export promotion agencies is due to international effort spearheaded by International Trade Center. The aim of this paper is to point out types and methods of marketing instruments application in trade promotion and to present the effectiveness of these instruments applications.

    A number of new, ultra-low-powered radiation instruments have recently been developed at Los Alamos. Among these are two instruments which use a novel power source to eliminate costly batteries. The newly developed gamma detecting radiac, nicknamed the Firefly, and the alpha particle detecting instrument, called the Simple Cordless Alpha Monitor, both use recent advances in miniaturization and powersaving electronics to yield devices which are small, rugged, and very power-frugal. The two instruments consume so little power that the need for batteries to run them is eliminated. They are, instead, powered by a charged capacitor which will operate the instruments for an hour or more. Use of a capacitor as a power source eliminates many problems commonly associated with battery-operated instruments, such as having to open the case to change batteries, battery storage life, availability of batteries in the field, and some savings in weight. Both line power and mechanical sources are used to charge the storage capacitors which power the instruments

  13. How To Control Color Appearance With Instrumentation

    Science.gov (United States)

    Burns, Margaret E.

    1980-05-01

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

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

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

    PC based data-acquisition has emerged as a rapidly developing area particularly with respect to process instrumentation. Computer based data acquisition in process instrumentation combined with Supervisory Control and Data Acquisition (SCADA) software has introduced extensive possibilities with respect to formats for presentation of information. The concept of presenting data using any instrument format with the help of software tools to simulate the instrument on screen, needs to be understood, in order to be able to make use of its vast potential. The purpose of this paper is to present the significant features of the Virtual Instrumentation concept and discuss its application in the instrumentation and control system of containment studies facility (CSF). Factors involved in the development of the virtual instrumentation based I and C system for CSF are detailed and a functional overview of the system configuration is given. (author)

    Random fluctuations of neutron flux, temperature, and pressure in a reactor provide multifrequency excitation of the corresponding instrumentation chains. Mathematical descriptors suitable for characterizing the output, or noise, of the instrumentation are reviewed with a view toward using such noise in detecting instrument faults. Demonstrations of the feasibility of this approach in a number of reactors provide illustrative examples. Comparisons with traditional surveillance testing are made, and a number of advantages and some disadvantages of using noise analysis as a supplementary technique are pointed out

    A Monte Carlo simulation is an important computational tool used in many areas of science and engineering. The use of Monte Carlo techniques for simulating neutron scattering instruments is discussed. The basic ideas, techniques and approximations are presented. Since the construction of a neutron scattering instrument is very expensive, Monte Carlo software used for design of instruments have to be validated and tested extensively. The McStas software was designed with these aspects in mind and some of the basic principles of the McStas software will be discussed. Finally, some future prospects are discussed for using Monte Carlo simulations in optimizing neutron scattering experiments. (R.P.)

  19. Particle size distribution instrument. Topical report 13

    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.

  20. CRITICAL ANALYSIS OF THEIR RISK FINANCIAL INSTRUMENTS

    Full Text Available In the last decade, accounting for financial instruments has experienced a revolution, following the publication of accounting rules on recognition and measurement of these instruments saddle. Need to develop standards for financial instruments appeared on the background of explosion using derivatives and the markets in which they are traded, and as a result of numerous financial scandals that rocked developed countries in the last decade. These were based, among other causes, improper use of derivatives and hiding their disastrous effects of poor management by keeping them off balance and failure to provide related information in the notes of the financial statements.
