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

    The "Bonn University Simultaneous CAmera" (BUSCA) is a CCD camera system which allows simultaneous direct imaging of the same sky area in four colors. The optics are designed for an f/8 beam and four 4Kx4K CCDs with 15m pixels covering a field of view of 12 arcmin x 12 arcmin at a 2m class telescope. In September 1998 BUSCA has seen "First Light". The instrument is based on three dichroic beam splitters which separate optical wavelength bands such (at 430nm, 540nm, 730nm) that standard astronomical intermediate-band filter systems can be used. The dichroics are made of plane-parallel glass plates mounted at an angle of 45 degrees. Astigmatism in the transmitted beams (f/8) is completely cancelled by identical plane-parallel glass plates of suitable orientation. BUSCA offers new perspectives in astronomical multicolor photometry: i) The broadband spectral properties (e.g. color indices) of astronomical objects in the optical can be determined with high reliability even in non-photometric atmospheric conditions...

  3. Corpocidade: arte enquanto micro-resistência urbana

    2009-08-01

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

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

    2014-12-01

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

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

    2015-12-01

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

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

    Directory of Open Access Journals (Sweden)

    Maria de Lourdes de Azevedo Barbosa

    2012-11-01

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

    1997-01-01

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

  11. BUSCA-JUN91. Reference manual for the calculation of radionuclide scrubbing in water pools

    International Nuclear Information System (INIS)

    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 modelled as well as the removal of soluble vapour 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 Reference. 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. (orig.)

    Full Text Available Criatividade, intuição, imaginação, determinação, ambição compreendem atributos que podem caracterizar um intelecto humano. As pessoas, no dia-a-dia, fazem uso desses ingredientes em variados momentos onde precisam tomar decisões e/ou prover soluções a problemas, além de empregá-las no processo de inovação. Entretanto, ao observar o ‘caminhar’ das pessoas e das organizações, percebe-se que o momento atual e vindouro é enriquecido e apoiado por intensos mecanismos de comunicação. A comunicação é essencial para solucão de problemas, para educação e uma miríade de atividades. Todavia, num momento da busca de solução ou num momento criativo, a reclusão pode constituir um diferencial. Nesse sentido, este artigo discute e explora esse paradoxo (se assim puder ser denominado de querer estar junto (com intensa comunicação ou recluso na busca do momento criativo ou solução de problema.

    2015-06-01

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

    2013-12-01

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

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

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

Experimentos computacionais foram realizados em quatro conjuntos de dados disponíveis na literatura. Os resultados mostram que a BD é robusta e competitiva em termos de qualidade das soluções obtidas e tempo computacional para o PRV Clássico, para os conjuntos de dados testados.In this paper we present a Scatter Search algorithm designed for the solution of the Classical Vehicle Routing Problem, giving details of each of its basic phases when applied to the routing problem. Scatter Search is an evolutionary meta-heuristic that combines solutions with the objective of obtaining new solutions of higher quality; even though there are similarities between Scatter Search and Genetic Algorithms, the two methods differ in basic principles. An important aspect of Scatter Search is to construct high quality solutions in order to direct the search to promising regions. Computational experiments were conducted using four data sets available in the literature. The results show that Scatter Search is robust and competitive in terms of both the quality of solutions and computational times, for the VRP data sets we used.

  4. Seismic instrumentation

    International Nuclear Information System (INIS)

    For better understanding of the specification for seismic instrumentation of a nuclear power plant, the lecture gives some fundamental remarks to the seismic risk in the Federal Republic of Germany and to the data characterizing an earthquake event. Coming from the geophysical properties of an earthquake, the quantities are explained which are used in the design process of nuclear power plants. This process is shortly described in order to find the requirements for the specification of the seismic instrumentation. In addition the demands of licensing authorities are given. As an example the seismic instrumentation of KKP-1, BWR, is shown. The paper deals with kind and number of instruments, their location in the plant and their sensitivity and calibration. Final considerations deal with the evaluation of measured data and with plant operation after an earthquake. Some experience concerning the earthquake behaviour of equipment not designed to withstand earthquake loads is mentioned. This experience has initiated studies directed to quantification of the degree of conservatism of the assumptions in the seismic design of nuclear power plants. A final garget of these studies are more realistic design rules. (RW)

  5. RHIC instrumentation

    International Nuclear Information System (INIS)

    The Relativistic Heavy Ion Collider (RHIC) consists of two 3.8 km circumference rings utilizing 396 superconducting dipoles and 492 superconducting quadrupoles. Each ring will accelerate approximately 60 bunches of 1011 protons to 250 GeV, or 109 fully stripped gold ions to 100 GeV/nucleon. Commissioning is scheduled for early 1999 with detectors for some of the 6 intersection regions scheduled for initial operation later in the year. The injection line instrumentation includes: 52 beam position monitor (BPM) channels, 56 beam loss monitor (BLM) channels, 5 fast integrating current transformers and 12 video beam profile monitors. The collider ring instrumentation includes: 667 BPM channels, 400 BLM channels, wall current monitors, DC current transformers, ionization profile monitors (IPMs), transverse feedback systems, and resonant Schottky monitors. The use of superconducting magnets affected the beam instrumentation design. The BPM electrodes must function in a cryogenic environment and the BLM system must prevent magnet quenches from either fast or slow losses with widely different rates. RHIC is the first superconducting accelerator to cross transition, requiring close monitoring of beam parameters at this time. High space-charge due to the fully stripped gold ions required the IPM to collect magnetically guided electrons rather than the conventional ions. Since polarized beams will also be accelerated in RHIC, additional constraints were put on the instrumentation. The orbit must be well controlled to minimize depolarizing resonance strengths. Also, the position monitors must accommodate large orbit displacements within the Siberian snakes and spin rotators. The design of the instrumentation will be presented along with results obtained during bench tests, the injection line commissioning, and the first sextant test. copyright 1998 American Institute of Physics

    Nodari, Paulo César

    2011-01-01

    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.

From that model came out meaningful insights about market structure and technological change relationship. Despite the improvements made by evolutionary models that have arisen since Nelson and Winter's book, this stream of models still shares some of the original limitations from Nelson and Winter's model. All of those limitations are related to the technological search part of the model. Thus, this article aims to build a new technological search model with properties (technological cumulativeness, asymmetrical R&D spillovers and knowledge accumulation and intertemporal depreciation that are capable to solve those limitations.

    As hortas urbanas são uma contribuição única para o espaço urbano. São uma memória do que o campo terá sido – uma paisagem ruralizada, ainda acessível no coração da cidade, um espaço onde se tem a ilusão de estar no campo. Uma paisagem ruralizada, tranquila mas partilhada.Em comum com outros tipos de agricultura urbana, as hortas urbanas desafiam as noções convencionais de cidade e de campo como espaços urbanos produtivos em crescimento.

    Full Text Available INTRODUÇÃO: O estudo foi desenvolvido com o objetivo de avaliar a situação da hanseníase na população adulta do Município de Buriticupu, MA. MÉTODOS: Foi empregado o método de busca ativa na identificação de casos novos, no período de 2005 a 2007. Baciloscopia de raspado intradérmico foi feita em todos os pacientes com lesões de pele compatíveis com hanseníase, enquanto exame histopatológico foi feito naqueles em que havia dúvidas na definição da forma clínica. RESULTADOS: Participaram do estudo 15.409 indivíduos, tendo o exame clínico definido o diagnóstico de hanseníase em 62 pacientes, o que representa um coeficiente de detecção de 40,23/10.000. A baciloscopia foi positiva em seis pacientes, sendo predominante a forma clínica tuberculóide, em 31 casos, seguida da forma indeterminada em 20, dimorfa em 10 e virchowiana em um. O estudo permitiu, ainda, a identificação de outras doenças da pele, tais como pitiríase versicolor, dermatofitose, escabiose, vitiligo e carcinoma de pele. CONCLUSÕES: O elevado coeficiente de detecção define o município como hiperendêmico para a hanseníase. A busca ativa de casos é um método importante para o controle da doença.INTRODUCTION: This study aimed to analyze the leprosy situation, focusing on the adult population of the town of Buriticupu, State of Maranhão.

    Full Text Available Inventar e reinventar a língua implica conceber a possibilidade de um sujeito (entendido aqui como aquele que se institui como tal em um ato de enunciação agir com e sobre a língua. A constituição da identidade desse sujeito pressupõe o reconhecimento do outro, num processo de intersubjetividade, por natureza condicionada à dialogicidade, princípios basilares do processo enunciativo. Os estudos lingüísticos pós-saussurianos, que nas últimas décadas se têm ocupado da atividade lingüística e compõem a chamada lingüística da enunciação, têm recebido, por suas diferenciadas abordagens dessa atividade, múltíplas sitematizações: Bakhtin o fez pela proposição da tese do diálogismo lingüístico e pelas formas da voz de outrem; Benveniste, pela proposição da subjetividade na língua, analisando os indicadores de subjetividade e sistematizando o aparelho formal da enunciação. Recortes bakhtinianos e benvenistianos entendidos nesta busca como complementares para a definição de uma concepção lingüística capaz de dar conta do processo interlocutivo constituem, pois, o objeto de estudo deste artigo.

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.

No texto são explorados os conceitos de sentido, compreensão, ação, ação social, relação social dentre outros. São apresentados também a tipologia da ação e os dois níveis de análise sociológica (microssocial e macrossocial na concepção de Weber, para quem a ação é fruto da subjetividade. Já para Schutz, a ação é intersubjetiva, socializada e a compreensão está por detrás da ação, quer para o sentido que o ator dá a sua própria ação (subjetivo, quer para a ação de seu semelhante (intersubjetivo. Tendo em vista essas teorias, este trabalho apresenta os pontos divergentes e convergentes entre elas, mas acima de tudo, registra o quanto são complementares na busca de compreensão do sentido da ação social.  Além dos preceitos conceituais, o texto discute a construção e a aplicação do modelo “tipo ideal” (TI amparados numa concepção schutziana.

    Dentro da produção da UPA, estúdio que buscou rivalizar esteticamente com os preceitos da Disney no cinema de animação nos anos 1950, Gerald McBoing-Boing é a personagem mais emblemática, estrelando quatro curtas de animação que representam os preceitos do estúdio. No entanto, o mote narrativo de McBoing-Boing é que ele não se comunica com sons, mas sim por efeitos sonoros, e se fazendo entender. Para entender quais são as possibilidades linguísticas desse uso sonoro e como ele não nos aparece enquanto algo surreal, analisaremos tal representação à luz da segunda filosofia de Ludwig Wittgenstein, cuja obra-chave são as Investigações Filosóficas. Concentrando no §528, o objetivo é mostrar como McBoing-Boing se encaixa em um fenômeno language-like, representando um ponto central na crítica estética da UPA.

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

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

    This book contains a selection of papers and articles in instrumentation previously pub­ lished in technical periodicals and journals of learned societies. Our selection has been made to illustrate aspects of current practice and applications of instrumentation. The book does not attempt to be encyclopaedic in its coverage of the subject, but to provide some examples of general transduction techniques, of the sensing of particular measurands, of components of instrumentation systems and of instrumentation practice in two very different environments, the food industry and the nuclear power industry. We have made the selection particularly to provide papers appropriate to the study of the Open University course T292 Instrumentation. The papers have been chosen so that the book covers a wide spectrum of instrumentation techniques. Because of this, the book should be of value not only to students of instrumen­ tation, but also to practising engineers and scientists wishing to glean ideas from areas of instrumen...

    It is pointed out that no instrument is sensitive to only one oceanographic variable; rather, each responds to a combination of atmospheric and oceanic phenomena. This complicates data interpretation and usually requires that a number of observations, each sensitive to somewhat different phenomena, be combined to provide unambiguous information. The distinction between active and passive instruments is described. A block diagram illustrating the steps necessary to convert data from satellite instruments into oceanographic information is included, as is a diagram illustrating the operation of a radio-frequency radiometer. Attention is also given to the satellites that carry the various oceanographic instruments.

    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.

    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.

    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. Palavras-chave: Espiritual. Busca de vida. Psicologia da religião. Viktor Frankl. Karl Jaspers.

    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....

    1992-09-01

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

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

    2014-06-01

    Full Text Available In most of the cases, the materials are tested in laboratories and designs are based on assumptions that the same results will be met with, during actual construction. As there are always large variations in materials, their properties, construction methods and their control, the actual product defers from the original assumptions. In this paper, instruments required to check the behaviour and stability of dams are discussed with their necessity, use and operation. These instruments prove to be much useful in proper maintenance of dam, and hence they should be installed under the guidance of experts at appropriate places in the dam. A conclusion has been arrived that there should be close co-operation between the designers, instrumentation specialist, expert analysis and site authorities to achieve the goal of instrumentation.

    Bader, Rolf; Hansen, Uwe

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

  14. Water level instrumentation simulation

    International Nuclear Information System (INIS)

    Through simulation, evaluations of system performance can be made to increase efficiency, reduce costs, enhance safety and provide effective training. A full function simulation for evaluating water level measurement requires modeling the physical process, the process instrumentation response and where appropriate, the human input/response. This paper examines a full function application simulating the primary system water level in a Boiling Water Reactor (BWR). The physical processes associated with BWR vessel level response are modeled with the Modular Accident Analysis Program (MAAP). The MAAP code is used as the basis for providing primary system and containment thermal-hydraulic response to a compendium of expected plant transients. The BWR vessel level instruments is modeled with the FAI developed Instrumentation PACkage (IPAC). With the thermal-hydraulic input from MAAP, the IPAC software models the various phenomena associated with water level measurements including the effects due to: (1) instrument channel calibration, (2) instrument drift and (3) containment (drywell) environmental effects. This paper discusses the IPAC models (instrumentation components) along with the factors which influence the mass balance of water in the downcomer region. A comparison of the BWR vessel water level complete simulation package to data from a simulated BWR plant transient culminates the discussion of this paper. The full function simulation package presented in this paper, enables a software-based representation of the BWR vessel level to be evaluated under various hypothetical plant conditions including normal, accident, and severe accident events.

    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.

    International Nuclear Information System (INIS)

    In the last few years a much greater emphasis has been placed upon understanding, controlling and monitoring the environmental effects of the advancing technologies. This has resulted in rapid advances in techniques for environmental monitoring. To aid the concerned scientist in keeping abreast of these developments, the Lawrence Berkeley Laboratory publishes a collection of volumes entitled Instrumentation for Environmental Monitoring. Separated into four volumes covering four media, AIR, WATER, RADIATION, and BIOMEDICAL, they provide a source book for three types of material: (1) Monitoring Rationale. They describe the characteristics, forms, and effects of a wide variety of pollutants and the means of controlling them. Federal regulations are explained and summarized. (2) Analytical Techniques. Methods of determining specific pollutants are described with special emphasis on the principles that form the basis of instrumental methods. (3) Commercial Instrumentation. The features of most commercially available instrumentation used for the determination and monitoring of each pollutant are presented in a manner that facilitates instrumental comparisons. Examples of the types of material in the volumes and the use of the volumes are presented

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

    Due to alterations made, the present reactor instrumentation is a mixture of old electron tube and modern semiconductor techniques. This mixture and the limited space in the control console, a non-modular system etc. render the making of service, maintenance and improvements difficult. Problems concerning the obtaining of spare parts for the old instrumentation are also expected. The present cabling will not be satisfactory in the long run and the risk of fires is significant. There is one common high voltage source for all four neutron detectors and no redundancy. Separate HV supplies including trip actuators are recommended for the nuclear channels. The water activity measurement system (with a GM tube) in the primary circuit is insufficient. Some modifications and replacements have been made in the present instrumentation, but it can hardly be used 10-20 years ahead without extensive replacements. It has been decided to renew the whole instrumentation in 1981. Much emphasis will be laid on standardization, flexibility, reliability, service and repair possibilities. The new instrumentation will be based on modern industrial standard modular units, cards etc. (including standardized signal output ranges, electronic testing possibilities, the use of isolation amplifiers etc.). Since the development in electronics is rapid, provisions should be made for some changes in the future. Standard unit and module systems make it easier to carry out such changes

    2009-01-01

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

    Recent interest in reprocessing nuclear fuel in the U.S. has led to advanced separations processes that employ continuous processing and multiple extraction steps. These advanced plants will need to be designed with state-of-the-art instrumentation for materials accountancy and control. This research examines the current and upcoming instrumentation for nuclear materials accountancy for those most suited to the reprocessing environment. Though this topic has received attention time and again in the past, new technologies and changing world conditions require a renewed look and this subject. The needs for the advanced UREX+ separations concept are first identified, and then a literature review of current and upcoming measuring techniques is presented. The report concludes with a preliminary list of recommended instruments and measurement locations.

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.

  5. Characteristics of protective instrumentation

    International Nuclear Information System (INIS)

    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.)

  6. Ozone Monitoring Instrument

    Science.gov (United States)

    de Vries, Johan

    The Ozone Monitoring Instrument is a trace gas monitoring instrument in the line of GOME (ERS-2) and Sciamachy (ENVISAT). Following these instruments, OMI provides UV-visible spectroscopy with a resolution sufficient to separate out the various absorbing trace gases (using DOAS or `Full' retrieval), but shaped as an imaging spectrometer. This means that a two dimensional detector is used where one dimension records the spectrum and the other images the swath. The scanning mechanism from the GOME and Sciamachy is not required anymore and there are considerable advantages with respect to simultaneous measurement of swath pixels, polarisation and obtainable swath width. The OMI consortium for a phase B is formed by Fokker Space & Systems and TPD in the Netherlands and VTT in Finland. In the presentation UV-visible atmospheric remote sensing will be placed in perspective and the OMI will be explaned.

  7. Eigenvalues and musical instruments

    Howle, V. E.; Trefethen, Lloyd N.

    2001-10-01

    Most musical instruments are built from physical systems that oscillate at certain natural frequencies. The frequencies are the imaginary parts of the eigenvalues of a linear operator, and the decay rates are the negatives of the real parts, so it ought to be possible to give an approximate idea of the sound of a musical instrument by a single plot of points in the complex plane. Nevertheless, the authors are unaware of any such picture that has ever appeared in print. This paper attempts to fill that gap by plotting eigenvalues for simple models of a guitar string, a flute, a clarinet, a kettledrum, and a musical bell. For the drum and the bell, simple idealized models have eigenvalues that are irrationally related, but as the actual instruments have evolved over the generations, the leading five or six eigenvalues have moved around the complex plane so that their relative positions are musically pleasing.

    2011-01-01

    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.

  1. Power station instrumentation

    International Nuclear Information System (INIS)

    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.

  9. Radiation monitoring instruments

    International Nuclear Information System (INIS)

    Radiation exposure to humans can be broadly classified as internal and external exposure. Sealed sources, which are unlikely to cause internal exposure, are used almost exclusively in radiotherapy. This chapter deals with the monitoring of external exposures. 1) External exposure monitoring refers to measuring: Radiation levels in and around work areas; Radiation levels around radiotherapy equipment or source containers; . Equivalent doses received by individuals working with radiation. 2) Radiation monitoring is carried out: to assess workplace conditions and individual exposures; To ensure acceptably safe and satisfactory radiological conditions in the workplace; to keep records of monitoring, over a long period of time, for the purposes of regulation or good practice. 3) Radiation monitoring instruments are used both for area monitoring and for individual monitoring. The instruments used for measuring radiation levels are referred to as area survey meters (or area monitors) and the instruments used for recording the equivalent doses received by individuals working with radiation are referred to as personal dosimeters (or individual dosimeters). All instruments must be calibrated in terms of the appropriate quantities used in radiation protection

    Uin, J. [Brookhaven National Lab. (BNL), Upton, NY (United States)

    2016-03-01

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

    1996-12-01

    As a result of a pre-phase a study, founded by ESA, this paper presents the definition of a spaceborne Rain Radar, candidate instrument for earth explorer precipitation mission. Based upon the description of user requirements for such a dedicated mission, a mission analysis defines the most suitable space segment. At system level, a parametric analysis compares pros and cons of instrument concepts associated with rain rate retrieval algorithms in order to select the most performing one. Several trade-off analysis at subsystem level leads then to the definition of the proposed design. In particular, as pulse compression is implemented in order to increase the radar sensitivity, the selected method to achieve a pulse response with a side-lobe level below--60 dB is presented. Antenna is another critical rain radar subsystem and several designs are com pared: direct radiating array, single or dual reflector illuminated by single or dual feed arrays. At least, feasibility of centralized amplification using TWTA is compared with criticality of Tx/Rx modules for distributed amplification. Mass and power budgets of the designed instrument are summarized as well as standard deviations and bias of simulated rain rate retrieval profiles. The feasibility of a compliant rain radar instrument is therefore demonstrated.

    2007-11-01

    Remote science operations require automated systems that can both act and react with minimal human intervention. One such vision is that of an intelligent instrument that collects data in an automated fashion, and based on what it learns, decides which new measurements to take. This innovation implements experimental design and unites it with data analysis in such a way that it completes the cycle of learning. This cycle is the basis of the Scientific Method. The three basic steps of this cycle are hypothesis generation, inquiry, and inference. Hypothesis generation is implemented by artificially supplying the instrument with a parameterized set of possible hypotheses that might be used to describe the physical system. The act of inquiry is handled by an inquiry engine that relies on Bayesian adaptive exploration where the optimal experiment is chosen as the one which maximizes the expected information gain. The inference engine is implemented using the nested sampling algorithm, which provides the inquiry engine with a set of posterior samples from which the expected information gain can be estimated. With these computational structures in place, the instrument will refine its hypotheses, and repeat the learning cycle by taking measurements until the system under study is described within a pre-specified tolerance. We will demonstrate our first attempts toward achieving this goal with an intelligent instrument constructed using the LEGO MINDSTORMS NXT robotics platform.

    International Nuclear Information System (INIS)

    The wide variety of science that can be presented with neutron scattering essentially boils down to determine two vectors, the momentum k of the neutron before it hits the sample and after it leaves the sample. All experimentally obtainable information is contained in the probability distribution W(k,k') of a neutron to undergo scattering takes it from k to k'. In this paper we will introduce the principles and concepts to understand what one is doing if one perform an experiment on a certain instrument We will describe the components of which almost all neutron scattering instruments are made up and their functions and show how these components can be combined to contribute in the best possible way to the solution of questions in a large number of scientific areas

  10. Embedded instrumentation systems architecture

    Science.gov (United States)

    Visnevski, Nikita A.

    2007-04-01

    This paper describes the operational concept of the Embedded Instrumentation Systems Architecture (EISA) that is being developed for Test and Evaluation (T&E) applications. The architecture addresses such future T&E requirements as interoperability, flexibility, and non-intrusiveness. These are the ultimate requirements that support continuous T&E objectives. In this paper, we demonstrate that these objectives can be met by decoupling the Embedded Instrumentation (EI) system into an on-board and an off-board component. An on-board component is responsible for sampling, pre-processing, buffering, and transmitting data to the off-board component. The latter is responsible for aggregating, post-processing, and storing test data as well as providing access to the data via a clearly defined interface including such aspects as security, user authentication and access control. The power of the EISA architecture approach is in its inherent ability to support virtual instrumentation as well as enabling interoperability with such important T&E systems as Integrated Network-Enhanced Telemetry (iNET), Test and Training Enabling Architecture (TENA) and other relevant Department of Defense initiatives.

  11. Tank depletion flow instruments

    International Nuclear Information System (INIS)

    A new flowmetering system is developed to measure and control flow without the need for an inline flowmeter. Flowrate is determined from the rate of level change in reference vessel. This system is unique in its use of balance pots for zero suppression to enable range amplification. The result is an accuracy in flow measurement and control as good as $plus or minus$1%. The system uses state-of-the-art digital integrated circuits with a crystal time base in conjunction with the time-proven pneumatic bubbler probe low range transmitters. The benefits are (1) reduced radiation exposure to personnel during maintenance of flowmeters for radioactive streams since instruments are all located in an operating area isolated from the process by four feet of concrete, (2) reduced volume of solid nuclear wastes through processing efficiencies, (3) reduced cost of chemicals involved, (4) increased speed of flowrate determination, (5) reduced maintenance time and material cost to correct flow instrument component failures, (6) no obstruction to flow in the process stream, and (7) reduced cost of instrumentation to determine flowrate. A disadvantage is the requirement that flow must be related to tank level thus only one unknown flow into or out of a given vessel at a time may be metered and controlled. 1 ref

  12. FHR Process Instruments

    Energy Technology Data Exchange (ETDEWEB)

    Holcomb, David Eugene [ORNL

    2015-01-01

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

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

    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.

  5. Radiation instrumentation: radiological chemistry

    International Nuclear Information System (INIS)

    Program efforts were concentrated in the following areas: development of low-level radiochemical laboratory techniques, in situ monitoring techniques, and activation analysis technology. Four different techniques were evaluated for borehole analysis of uranium and thorium ores. These involved the detection of fission product photons after 252Cf activation, the detection of low-energy gamma rays, the direct measurement of the 1001 keV photon from /sup 242m/Pa, a 238U daughter, and isotopic excitation x-ray fluorescence spectroscopy. X-ray fluorescence spectroscopy and detection of uranium daughter photons allowed 0.01% uranium to be detected. X-ray spectrometry of rare earth elements following activation analysis also allowed better elemental detection sensitivities to be obtained than did the detection of high-energy photons identified with a Ge(Li) detector in typical instrumental neutron activation analysis. An activation analysis facility is under development utilizing 252Cf in a 235U-fueled subcritical assembly. This assembly will be used to develop cyclic activation analysis techniques for some 65 elements in environmental matrices with sensitivities varying from parts per million to parts per billion. A study was initiated to identify instrumentation required for the measurement of transuranium elements associated with power reactor fuels. Transuranium isotopes, 237Pu, 238Pu, 239Pu, 241Am, 243Am, and 244Cm can be identified through low energy photons or x-rays emitted following alpha emission with planar intrinsic Ge detectors

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

    Although the promise of new positron emission tomography (PET) imaging agents is great, the process of bringing these agents to commercialization remains in its infancy. There are no PET products today that have gone through the full clinical and chemistry development process required to gain marketing approval by the US Food and Drug Administration (Fda). The purpose of this paper was to review validation from the perspective of the chemistry, manufacturing and controls (CMC) section of an Fda filing, as well as the validation requirements described in Fda good manufacturing practice (GMP) regulations, guidance documents and general chapters of the US Pharmacopoeia (Usp). The review includes discussion of validation from development to commercial production of PET radiopharmaceuticals with a special emphasis on equipment and instrumentation used in production and testing. The goal is to stimulate a dialog that leads to the standardization of industry practices and regulatory requirements for validation practices in PET.

    Energy Technology Data Exchange (ETDEWEB)

    Christian, David E. (Danbury, CT)

    1990-07-24

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

  14. Instrumentation Working Group Summary

    1999-01-01

    The Instrumentation Working Group compiled a summary of measurement techniques applicable to gas turbine engine aerosol precursors and particulates. An assessment was made of the limits, accuracy, applicability, and technology readiness of the various techniques. Despite advances made in emissions characterization of aircraft engines, uncertainties still exist in the mechanisms by which aerosols and particulates are produced in the near-field engine exhaust. To adequately assess current understanding of the formation of sulfuric acid aerosols in the exhaust plumes of gas turbine engines, measurements are required to determine the degree and importance of sulfur oxidation in the turbine and at the engine exit. Ideally, concentrations of all sulfur species would be acquired, with emphasis on SO2 and SO3. Numerous options exist for extractive and non-extractive measurement of SO2 at the engine exit, most of which are well developed. SO2 measurements should be performed first to place an upper bound on the percentage of SO2 oxidation. If extractive and non-extractive techniques indicate that a large amount of the fuel sulfur is not detected as SO2, then efforts are needed to improve techniques for SO3 measurements. Additional work will be required to account for the fuel sulfur in the engine exhaust. Chemical Ionization Mass Spectrometry (CI-MS) measurements need to be pursued, although a careful assessment needs to be made of the sampling line impact on the extracted sample composition. Efforts should also be placed on implementing non-intrusive techniques and extending their capabilities by maximizing exhaust coverage for line-of-sight measurements, as well as development of 2-D techniques, where feasible. Recommendations were made to continue engine exit and combustor measurements of particulates. Particulate measurements should include particle size distribution, mass fraction, hydration properties, and volatile fraction. However, methods to ensure that unaltered

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

    Full text: Promising students had a foretaste of the latest laboratory techniques at the ICFA 1993 India School on Instrumentation in High Energy Physics held from February 15-26 and hosted by the Tata Institute of Fundamental Research (TIFR), Bombay. The scientific programme was put together by the ICFA Panel for Future Instrumentation, Innovation and Development, chaired by Tord Ekelof (Uppsala). The programme included lectures and topical seminars covering a wide range of detector subjects. In small groups, students got acquainted with modern detector technologies in the laboratory sessions, using experimental setups assembled in various institutes world-wide and shipped to Bombay for the School. The techniques covered included multiwire proportional chambers for detection of particles and photons, gaseous detectors for UV photons and X-ray imaging, the study of charge drift in silicon detectors, measurement of the muon lifetime using liquid scintillators, tracking using scintillating fibres, and electronics for sensitive detectors. The India School was attended by around 80 students from 20 countries; 34 came from Indian universities. It was the fifth in this series, previous Schools having been at Trieste (1987, 1989 and 1991) organized by the ICFA Panel and hosted and sponsored by the International Centre for Theoretical Physics, and in 1990, organized at Rio de Janeiro in collaboration with the Centro Brasileiro de Pesquisas Fisicas. The School was jointly directed by Suresh Tonwar (TIFR), Fabio Sauli (CERN) and Marleigh Sheaff (University of Wisconsin), and sponsored by TIFR and DAE (India), CERN (Switzerland), ICTP and INFN (Italy), British Council and RAL (UK), NSF and DOE (USA), KEK (Japan), IPP (Canada) and DESY (Germany)

Se conoce muy poco acerca de los procesos de aprendizaje en anfibios, y aún menos respecto de las relaciones cerebro-aprendizaje. Recientemente hemos comenzado el estudio sistemático del aprendizaje instrumental en el sapo Bufo arenarum dentro de un marco comparativo. Se observaron diversos fenómenos de aprendizaje comunes a una amplia variedad de vertebrados, tales como la adquisición bajo condiciones de entrenamiento masivo y espaciado, la extinción, la recuperación espontánea, el efecto subsiguiente al refuerzo, y el efecto en al adquisición de la magnitud del reforzamiento. Además, comenzamos el análisis de los efectos sobre el aprendizaje de las lesiones del pallium medial (estructura postulada como homóloga al hipocampo de los mamíferos. La lesión del paIlium medial no tuvo efectos sobre el desempeño ni sobre la tasa de captación de agua durante la adquisición. Pero retardó significativamente la extinción de la respuesta instrumental en un corredor recto. Estos datos sugieren que el palli um medial de los sapos juega un papel en la inhibición de respuestas previamente aprendidas. Los resultados de nuestros estudios en el sapo Bufo arenarum aportan datos origi na1es a la limitada información disponible sobre aprendizaje en anfibios.

  1. Virtual instrument simulator for CERES

    Chapman, John J.

    1997-12-01

    A benchtop virtual instrument simulator for CERES (clouds and the Earth's radiant energy system) has been built at NASA, Langley Research Center in Hampton, Virginia. The CERES instruments will fly on several earth orbiting platforms notably NASDA's tropical rainfall measurement mission (TRMM) and NASA's Earth observing system (EOS) satellites. CERES measures top of the atmosphere radiative fluxes using microprocessor controlled scanning radiometers. The CERES virtual instrument simulator consists of electronic circuitry identical to the flight unit's twin microprocessors and telemetry interface to the supporting spacecraft electronics and two personal computers (PC) connected to the I/O ports that control azimuth and elevation gimbals. Software consists of the unmodified TRW developed flight code and ground support software which serves as the instrument monitor and NASA/TRW developed engineering models of the scanners. The CERES instrument simulator will serve as a testbed for testing of custom instrument commands intended to solve in-flight anomalies of the instruments which could arise during the CERES mission. One of the supporting computers supports the telemetry display which monitors the simulator microprocessors during the development and testing of custom instrument commands. The CERES engineering development software models have been modified to provide a virtual instrument running on a second supporting computer linked in real time to the instrument flight microprocessor control ports. The CERES instrument simulator will be used to verify memory uploads by the CERES flight operations TEAM at NASA. Plots of the virtual scanner models match the actual instrument scan plots. A high speed logic analyzer has been used to track the performance of the flight microprocessor. The concept of using an identical but non-flight qualified microprocessor and electronics ensemble linked to a virtual instrument with identical system software affords a relatively

    Tissue mechanical properties reflect extracellular matrix composition and organization, and as such, their changes can be a signature of disease. Examples of such diseases include intervertebral disk degeneration, cancer, atherosclerosis, osteoarthritis, osteoporosis, and tooth decay. Here we introduce the tissue diagnostic instrument (TDI), a device designed to probe the mechanical properties of normal and diseased soft and hard tissues not only in the laboratory but also in patients. The TDI can distinguish between the nucleus and the annulus of spinal disks, between young and degenerated cartilage, and between normal and cancerous mammary glands. It can quantify the elastic modulus and hardness of the wet dentin left in a cavity after excavation. It can perform an indentation test of bone tissue, quantifying the indentation depth increase and other mechanical parameters. With local anesthesia and disposable, sterile, probe assemblies, there has been neither pain nor complications in tests on patients. We anticipate that this unique device will facilitate research on many tissue systems in living organisms, including plants, leading to new insights into disease mechanisms and methods for their early detection.

  12. Detectors for Tomorrow's Instruments

    2009-01-01

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

    2015-05-01

    Cleaning, decontaminating, and handling instructions for instruments vary widely based on the type of instrument and the manufacturer. Processing instruments in accordance with the manufacturer's instructions can help prevent damage and keep devices in good working order. Most importantly, proper cleaning and disinfection may prevent transmission of pathogenic organisms from a contaminated device to a patient or health care worker. The updated AORN "Guideline for cleaning and care of surgical instruments" provides guidance on cleaning, decontaminating, transporting, inspecting, and storing instruments. This article focuses on key points of the guideline to help perioperative personnel implement appropriate instrument care protocols in their practice settings. The key points address timely cleaning and decontamination of instruments after use; appropriate heating, ventilation, and air conditioning parameters for the decontamination area; processing of ophthalmic instruments and laryngoscopes; and precautions to take with instruments used in cases of suspected prion disease. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures. PMID:25946180

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.

    After analyzing and comparing the traditional automobile instrument, the onboard instrument based on virtual instrument technology is designed in this paper. The PC/104 computer was employed as the core processing unit of the onboard instrument, and the several intelligent data acquisition nodes are set and connected by the CAN bus, through which the nodes can communicate with the core processing unit. The information of the vehicle's working condition can be displayed synthetically by adopting virtual instrument technology. When the working condition goes beyond its limit, the system can emit an alarm, record and storage the abnormal condition automatically, and suggest how to deal with the abnormity urgently. The development background and design idea of onboard information system were elaborated in the paper. The software, the hardware architecture and the principle of onboard information system were introduced in detail.

  17. Tuning the instrument

    International Nuclear Information System (INIS)

    The Clean Development Mechanism (CDM) has been vital in implementing the Kyoto Protocol. Its achievements are remarkable - particularly since the climate regime had no market experience just five years ago. The Protocol's market mechanisms are the United Nations' first attempt to create and regulate a global commodity. But the Protocol was never intended as the solution to climate change, nor were its market mechanisms seen as final products. The Protocol is limited in its global emission reduction target, in its timeframe, and in the countries that participate. Given the scale of the climate challenge, it can only be a preamble to an extended and enhanced effort - continuing to rely heavily on market mechanisms which may have to evolve to leverage the necessary capital and technology transfer. The Stern Review estimates that $20-30 billion per year must be invested to cover the incremental costs of decarbonisation. The annual deployment of capital through primary CDM transactions doubled from $2.4 billion to $4.8 billion between 2005 and 2006, and is doubling again in 2007. But this is still only a fraction of what is needed. The CDM can, and must, do better. For industrialized countries the CDM's purpose is to cut enough emissions to lower the cost of their reduction commitments under the Protocol. The CDM has registered over 900 projects with a potential of delivering up to 1 billion tonnes of CO2 by the end of 2012. At least another 1800 projects - which could deliver another 1.5 billion tonnes by then - are in the pipeline. For developing countries, the CDM has two purposes: to promote domestic sustainable development and to help stabilize global greenhouse gas concentrations in the atmosphere. These goals require it to be an effective instrument for decarbonising developing countries' trajectories of production and consumption. Here it has not performed quite so well

  18. Zach's instruments and their characteristics

    Wolfschmidt, Gudrun

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

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

  2. Smart antennas for nuclear instruments

    International Nuclear Information System (INIS)

    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

  3. Instrumental variables and Mendelian randomization with invalid instruments

    Science.gov (United States)

    Kang, Hyunseung

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

    There are several microwave instruments in low Earth orbit (LEO) that are used for atmospheric temperature and humidity sounding in conjunction with companion IR sounders as well as by themselves. These instruments have achieved a certain degree of maturity and undergoing a redesign to minimize their size, mass, and power from the previous generation instruments. An example of these instruments is the AMSU-A series, now flying on POES and AQUA spacecraft with the IR sounders HIRS and AIRS. These older microwave instruments are going to be replaced by the ATMS instruments that will fly on NPP and NPOESS satellites with the CrIS sounder. A number of techniques learned from the ATMS project in instrument hardware design and data processing are directly applicable to a similar microwave sounder on a geosynchronous platform. These techniques can significantly simplify the design of a Geostationary orbit (GEO) microwave instrument, avoiding costly development and minimizing the risk of not being able to meet the scientific requirements. In fact, some of the 'enabling' technology, such as the use of MMIC microwave components (which is the basis for the ATMS' much reduced volume) can be directly applied to a GEO sounder. The benefits of microwave sounders are well known; for example, they penetrate non-precipitating cloud cover and allow for use of colocated IR observations in up to 80% cloud cover. The key advantages of a microwave instrument in GEO will be the ability to provide high temporal resolution as well as uniform spatial resolution and extend the utility of a colocated advanced IR sounder to cases in which partial cloud cover exists. A footprint of the order of 100 km by 100 km resolution with hemispherical coverage within one hour can be easily achieved for sounding channels in the 50 to 59 GHz range. A GEO microwave sounder will also allow mesoscale sampling of select regions.

    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.

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

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

    International Nuclear Information System (INIS)

    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

  15. Instrumented testing of BCR Specimens

    International Nuclear Information System (INIS)

    Two times two reference batches of BCR material with nominal energies of 80J and 160J were impact tested on an instrumented machine. A good agreement was found between the friction-corrected dial energy and the integrated energy. Systematic differences have been detected between the two 80J batches: these differences do not occur in the typical force values and are a consequence of a post-maximum event. A small calibration difference exists for the 80J batches: this seems a consequence of the higher impact forces involved and suggests the influence of dynamic effects on the calibration (static, in-situ). The next step is to test similar batches on a non-instrumented impact tester to detect an eventual influence of the physical presence of instrumentation on the impact pot. It is expected that this effect will be minor

    A proposed optoelectronic instrument would perform several different spectroscopic and imaging functions that, heretofore, have been performed by separate instruments. The functions would be reflectance, fluorescence, and Raman spectroscopies; variable-color confocal imaging at two different resolutions; and wide-field color imaging. The instrument was conceived for use in examination of minerals on remote planets. It could also be used on Earth to characterize material specimens. The conceptual design of the instrument emphasizes compactness and economy, to be achieved largely through sharing of components among subsystems that perform different imaging and spectrometric functions. The input optics for the various functions would be mounted in a single optical head. With the exception of a targeting lens, the input optics would all be aimed at the same spot on a specimen, thereby both (1) eliminating the need to reposition the specimen to perform different imaging and/or spectroscopic observations and (2) ensuring that data from such observations can be correlated with respect to known positions on the specimen. The figure schematically depicts the principal components and subsystems of the instrument. The targeting lens would collect light into a multimode optical fiber, which would guide the light through a fiber-selection switch to a reflection/ fluorescence spectrometer. The switch would have four positions, enabling selection of spectrometer input from the targeting lens, from either of one or two multimode optical fibers coming from a reflectance/fluorescence- microspectrometer optical head, or from a dark calibration position (no fiber). The switch would be the only moving part within the instrument.

  1. Recent developments in nuclear instruments

    International Nuclear Information System (INIS)

    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

  8. Enhanced radiological detection instrument training

    International Nuclear Information System (INIS)

    Full text: Whether ensuring the security and safe use of recorded radioactive materials, or detecting, identifying and responding to radioactive materials out of regulatory control the provision of an ever increasing range of radiological dosimeters, survey meters and spectrometers does not, in itself, enhance nuclear security. These tools are only as good as the ability of deployed personnel to operate them correctly. It is therefore: essential that training in the coordinated use of such instruments be as realistic and comprehensive as possible. However, there is an inherent difficulty in using the real radiological detection instruments for training because such devices require radiological sources to generate response. Systems that simulate radioactive materials using ultrasound, electromagnetic, or fluorescent, powders/liquids are already firmly established within the radiological instrument training community. These simulated radioactive sources/materials create a response in simulation detection instruments, or simulation probes attached to real detection instruments, to enable the opportunity to provide safe instruction in the use of specific devices as well as the correct procedures during their deployment. In order to extend the opportunities for the comprehensive training of multiple personnel using multiple simulation instruments in a wide area field exercise scenario the PlumeSIM system has been developed by Argon Electronics LLP. RAD PlumeSIM is a dedicated element within the broader PlumeSIM product family, enabling instructor management of the response of radiological simulator instruments to fully configurable 'virtual plumes and hot spots', in real time, over a training area defined by user selected mapping. Instructors are provided with the ability to select the parameters for the exercise (including the type of radiation hazard, the release of single sod multiple sources, and a full range of environmental conditions), and record the actions of

  13. Mobile Instruments Measure Atmospheric Pollutants

    Science.gov (United States)

    2009-01-01

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

  16. Maintenance of nuclear medicine instruments

    International Nuclear Information System (INIS)

    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. These trends of the instrument design should be taken into consideration when a policy has to be developed for the repairs of the hospital based equipment

    Perotti, Jose; Santiago, Josephine; Mata, Carlos; Vokrot, Peter; Zavala, Carlos; Burns, Bradley

    2008-01-01

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

  13. Regeneration in brass wind instruments

    Science.gov (United States)

    Elliott, S. J.; Bowsher, J. M.

    1982-07-01

    This paper is concerned with the production of musical notes by the interaction between the lips of a player and a brass wind instrument. The mechanism of this non-linear oscillation, together with that in the voice and for woodwind instruments, is discussed and past theories reviewed. Each element in the interaction is then carefully delineated and reasonable approximations to the governing equations for the lip dynamics and flow conditions through the lip opening are deduced: the acoustic parameters of the instrument and pressure source from the lungs can be experimentally determined. In contrast to the case of woodwind instruments, for example, many of the important parameters controlling the interaction can vary over a wide range and are under the complete control of the player. The expressions describing each component of the interaction are then combined to form an overall theory of regeneration, following Helmholtz, which leads to a description of the conditions necessary for a note to be sustained, and to an expression describing the characteristic waveform of the mouthpiece pressure at low frequencies. Experimental measurements of this mouthpiece pressure are presented, together with measurements of the steady and alternating components of the pressure in the mouth, and of the velocity in the mouthpiece for blown notes on a trombone and trumpet. Good agreement was observed between the harmonics of the measured mouthpiece pressure and those deduced from theory. Measurements are presented of the intonation of a trombone, and the range and characteristics of notes "buzzed" on a mouthpiece alone are discussed. Finally the steady pressure in the mouth and the average flow down the instrument are used to calculate the average lip opening, and hence the effective mass of the moving parts of the lips for a variety of notes played on a trombone and trumpet.

    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.

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.

  2. Robust Instrumentation[Water treatment for power plant]; Robust Instrumentering

    Energy Technology Data Exchange (ETDEWEB)

    Wik, Anders [Vattenfall Utveckling AB, Stockholm (Sweden)

    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

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

    Full Text Available There are three main environmental management strategies so far developed to deal with the environmental quality concerns: command-and-control (CAC strategy, voluntary measures strategy (VM and economic instruments (EI or market type environmental management tools strategy. For an effective environmental management all these strategies should be utilized in a harmonized manner depending on the strengths and weaknesses of the surrounding economic, social and institutional circumstances of the societies such as availability of financial funds, status of internal market and citizen awareness over environmental issues. Individually all of these strategies do have their own superiorities and disadvantages as a tool to upgrade the environmental quality and to maintain it. However, when compared, it is observed that the environmental management tools which are mainly economic and financial in nature are gaining more recognition due to their efficiency and effectiveness. The article tries to introduce the economic and financial instruments of environmental management.

  5. Nuclear instrumentation for radiation measurement

    International Nuclear Information System (INIS)

    Nuclear radiation cannot be detected by human senses. Nuclear detectors and associated electronics facilitate detection and measurement of different types of radiation like alpha particles, beta particles, gamma radiation, and detection of neutrons. 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

    International Nuclear Information System (INIS)

    Fuji Electric developed a new type detector for gamma thickness gauges, inner-mill housing gamma thickness gauges at hot plate mills and tube-wall thickness gauges at hot seamless tube mills. This detector attained much higher gamma counting and much lower drift than our former detectors. We plan to apply this detector to our new type thickness gauges and also renewal of now working thickness gauges at customer's site. In addition, we developed a soil mass measuring instrument for on-line measurement of cutting soil mass in a waste water tube in shield tunneling. This instrument is free from legal control and can be used in every field of civil engineering. (author)

    2000-06-01

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

  9. Holy Trinity of Instrumentation Development

    International Nuclear Information System (INIS)

    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

    2005-01-01

    Small ions are part of the atmospheric aerosol spectrum, and study of ion-aerosol interactions is fundamental in atmospheric physics. Air ion physics and instrumentation are reviewed, including the historical context. A miniaturised Gerdien condenser for ion measurement, operating in situ to minimise inlet errors, is described. Two operating modes using independent current and voltage decay measurements are employed. A more sophisticated self-calibrating and fully programmable ion mobility spectrometer (PIMS) based on the same principles, is also discussed. Detailed analysis of error terms and application of new technology is demonstrated to greatly improve its capability. Self-consistent experimental approaches, including ionisation and ion concentration instruments, are used for calibration. In developing and characterising the individual components of the PIMS, favourable and unfavourable operating regimes are identified: this approach can also be applied to other aspiration ion counting techniques. Use of...

    International Nuclear Information System (INIS)

    A supplemental stress analysis of the LOFT Downcomer Instrumentation Assembly (DIA) has been completed in accordance with the stress requirements of Section III of the ASME Code. Both thermal loads, due to LOCE and operating conditions, and fluid loads were considered. The following conclusions were made: (1) Inconel 600 is an acceptable material for the pressure tubes. (2) The flowmeter can be attached to the DIA with 1/4-inch diameter, SA-193 type B8M screws. They should be lubricated with two coats of Neolube and torqued to 1.25 ft-lbs. This applies to all of the screws attaching the flowmeter to the DIA. As an alterative, SA-453, grade 600 screws may be used. They should be coated with 2 coats of Neolube and torqued to 4.9 ft-lbs (4.5 ft-lbs is acceptable). (3) The method of mounting the instrument leads and the pressure tubes is adequate

    1992-08-01

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

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

  12. Geotechnical instrumentation for repository shafts

    International Nuclear Information System (INIS)

    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

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.

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

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

Results of the studies were used to specify and procure an instrument with improved characteristics. The purpose of this paper is to describe the results of the studies and the design of the instrument. 6 refs., 6 figs., 4 tabs

  19. Multimodality instrument for tissue characterization

    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.

    Plescia, Carl T. (Inventor); Gamble, Donald W. (Inventor)

    1987-01-01

    A closed loop system reduces pointing errors in one or more spacecraft instruments. Associated with each instrument is a electronics package (3) for commanding motion in that instrument and a pointing control system (5) for imparting motion in that instrument in response to a command (4) from the commanding package (3). Spacecraft motion compensation logic (25) compensates for instrument pointing errors caused by instrument-motion-induced spacecraft motion. Any finite number of instruments can be so compensated, by providing each pointing control system (5) and each commanding package (3), for the instruments desired to be compensated, with a link to the spacecraft motion compensation logic (25). The spacecraft motion compensation logic (25) is an electronic manifestation of the algebraic negative of a model of the dynamics of motion of the spacecraft. An example of a suitable model, and computer-simulated results, are presented.

    With the aid of microcomputer hardware and software for the introductory physics laboratory, I have developed several experiments dealing with the properties of brass musical instruments that could be used when covering sound anywhere from an introductory physics laboratory to a course in musical acoustics, or even independent studies. The results of these experiments demonstrate in a quantitative fashion the effects of the mouthpiece and bell on the frequencies of the sound waves and thus the musical pitches produced. Most introductory sources only discuss these effects qualitatively.

  11. Rapidly Adaptable Instrumentation Tester (RAIT)

    International Nuclear Information System (INIS)

    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

  2. Instrumenting the Intelligence Analysis Process

    Energy Technology Data Exchange (ETDEWEB)

    Hampson, Ernest; Cowley, Paula J.

    2005-05-02

    The Advanced Research and Development Activity initiated the Novel Intelligence from Massive Data (NIMD) program to develop advanced analytic technologies and methodologies. In order to support this objective, researchers and developers need to understand what analysts do and how they do it. In the past, this knowledge generally was acquired through subjective feedback from analysts. NIMD established the innovative Glass Box Analysis (GBA) Project to instrument a live intelligence mission and unobtrusively capture and objectively study the analysis process. Instrumenting the analysis process requires tailor-made software hooks that grab data from a myriad of disparate application operations and feed into a complex relational database and hierarchical file store to collect, store, retrieve, and distribute analytic data in a manner that maximizes researchers’ understanding. A key to success is determining the correct data to collect and aggregate low-level data into meaningful analytic events. This paper will examine how the GBA team solved some of these challenges, continues to address others, and supports a growing user community in establishing their own GBA environments and/or studying the data generated by GBA analysts working in the Glass Box.

  4. Nuclear instrumentation for societal applications

    International Nuclear Information System (INIS)

    Every Nuclear Instrumentation System (NIS) is basically configured keeping in mind the target radiations that one is after and the end goals that the NIS has to meet. Target radiations could include, either individually or in combination, photons (γ), electrons (e-), positrons (e+), protons (p), neutrons (n), muons (μ), pions (π), alpha (α), ions (x+), neutrinos and so on. By a proper choice of front end detectors (such as a gas based ionization chamber, a solid state detector, a scintillator backed up by a photomultiplier tube, a nuclear reaction based detector and so on) supported by suitable electronics as well as software to process the output electrical signals, the designer has to ensure that the end goals of NIS are realised. Over the past few decades NI systems have seen remarkable advances and while areas related to nuclear energy, particle accelerators, radiation surveillance applications etc., which are the primary thrust of this 'National Symposium on Nuclear Instrumentation', will be covered by other speakers, in this talk we will endeavour to address use of NIS that are directly linked to societal benefits. In particular, we will cover applications in the areas of medical diagnosis, agriculture, mineral and oil prospecting investigation, hydrological and geochemical studies etc. Building NI systems for such applications, however, not only pose new challenges, but also offer tremendous opportunities, which will be highlighted during the talk.

  5. Pile Instrumentation Using Retrievable Sensors

    Directory of Open Access Journals (Sweden)

    Faisal H. Ali

    2008-01-01

    Full Text Available Strain gauges are normally used to monitor the shortening or compression of pile during static pile load test. For concrete spun pile, the technique used either by incorporating high temperature-resistant strain gauges into the heat-cured production process of the spun piles or by installing an instrumented steel pipe into the hollow core of the spun piles followed by cement grout infilling. The former is extremely unpopular due to high cost of these gauges and the uncertainty over their ability to survive the pile production and driving processes. The shortcoming of the other technique is the infilling of cement grout substantially alters the structural properties of the piles, thus rendering their load-response behaviour significantly different from that of the actual working piles. To address the difficulties of the above techniques a new method was recently developed by the authors, which uses retrieval sensors instead of strain gauges (which have to be sacrificed in every test. The method also has the ability to monitor loads and displacements at various levels along the pile shaft and toe of instrumented piles. Results of field tests show high quality, reliable and consistent data, clearly far exceeding the capability of both conventional and approximate methods of using strain gauges.

  6. Economic instruments for waste management

    International Nuclear Information System (INIS)

    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

    We describe a portable luminescence reader suitable for use in remote localities in the field. The instrument weighs about 8kg and is based around a 30mm bialkali photomultiplier detecting signals through a glass filter centered on 340nm. Stimulation is by 470nm blue LEDs (24W in total) operating...... in both continuous wave and pulsed mode; photon counting can be gated such that it is active only during the pulse off-period.

  8. In-core measuring instruments

    International Nuclear Information System (INIS)

    Purpose: To detect sounds generated in the reactor at high sensitivity and over in a wide frequency band and to accurately detect at which position boiling is generated. Constitution: In-core instruments are accommodated in a liquid of the same quality as the coolant in a guide tube corresponding to each of fuel assemblies. The measuring instruments are constituted by piezoelectric element, acoustic detector, thermoelectric couple, eddy-current type flowmeter and the like. When a boiling phenomenon appears in one of the fuel assemblies, the acoustic detector detects the temperature and the flow fluctuation of the coolant propagating the liquid, and sends out the output voltages of the same frequency from the M1 cable to the processing device. The processing device compares the output voltage signal with the memory of the acoustic signal in the normal state, and detects malfunction of the core to discriminate fuel assemblies in which boiling occurs. The fluctuations in the temperature and flow quantity due to the boiling phenomenon are detected by the eddy-current type flowmeter and thermoelectric couple, thus the malfunction of the core being detected rapidly.

  9. Program Instrumentation and Trace Analysis

    Science.gov (United States)

    Havelund, Klaus; Goldberg, Allen; Filman, Robert; Rosu, Grigore; Koga, Dennis (Technical Monitor)

    2002-01-01

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

  10. The HYDICE instrument design and its application to planetary instruments

    Science.gov (United States)

    Basedow, R.; Silverglate, P.; Rappoport, W.; Rockwell, R.; Rosenberg, D.; Shu, K.; Whittlesey, R.; Zalewski, E.

    The Hyperspectral Digital Imagery Collection Experiment (HYDICE) instrument represents a significant advance in the state of the art in hyperspectral sensors. It combines a higher signal-to-noise ratio (SNR) and significantly better spatial and spectral resolution and radio metric accuracy than systems flying on aircraft today. The need for 'clean' data, i.e., data free of sampling artifacts and excessive spatial or spectral noise, is a key driver behind the difficult combination of performance requirements laid out for HYDICE. Most of these involve the sensor optics and detector. This paper presents an optimized approach to those requirements, one that comprises push broom scanning, a single, mechanically cooled focal plane, a double-pass prism spectrometer, and an easily fabricated yet wide-field telescope. Central to the approach is a detector array that covers the entire spectrum from 0.4 to 2.5 microns. Among the major benefits conferred by such a design are optical and mechanical simplicity, low polarization sensitivity, and coverage of the entire spectrum without suffering the spectral gaps caused by beam splitters. The overall system minimizes interfaces to the C-141 aircraft on which it will be flown, can be calibrated on the ground and in flight to accuracies better than those required, and is designed for simple, push-button operation. Only unprocessed data are recorded during flight. A ground data processing station provides quick-look, calibration correction, and archiving capabilities, with a throughput better than the requirements. Overall performance of the system is expected to provide the solid database required to evaluate the potential of hyperspectral imagery in a wide variety of applications. HYDICE can be regarded as a test bed for future planetary instruments. The ability to spectrally image a wide field of view over multiple spectral octaves offers obvious advantages and is expected to maximize science return for the required cost and

  11. Probabilistic design verification of instrumented protection functions

    International Nuclear Information System (INIS)

    IEC 61508 supports performance based instrumentation design using probabilistic analysis of critical failure modes. This risk based approach has been used quite extensively in several industries and is applicable to nuclear designs as well. The IEC 61513 group of nuclear instrumentation standards mentions the subject but does not discuss detail. Probabilistic analysis of instrumentation requires inclusion of many important variables including the failure rates as a function of failure mode for all instruments, proof testing schedules and effectiveness, and common cause for all redundant components. This presentation will discuss methods and tools used to probabilistic failure analysis of instrumentation. (author)

    2014-11-01

    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.

  14. Role of microprocessors in nuclear instrumentation

    International Nuclear Information System (INIS)

    Like all the other kinds of electronic instruments, nuclear instrumentation has been more and more designed with built-in microprocessors, which give elaborated computed results in terms of user's units, control the sequence of successive tasks and introduce parallel actions in distributed systems. Compared to previous logic design, instrument dialog is better, recording facilities are increased and the price becomes lower. Microprocessors allow for a sophisticated self-made instrumentation by a small team, but this requires powerful tools for hardware and software debugging facilities, as well as a good knowledge. Three typical examples of applications are given: a nuclear counting automat, a programmable instrument and a simple distributed system. (author)

  15. Instrumentation for international safeguards. Present and future

    International Nuclear Information System (INIS)

    On-site inspection supported by instrumentation has become the primary verification mode for international safeguards. The custom designed instrumentation for measurement, monitoring, sealing and containment has become the essential tools to support inspectors. At present, 76 instruments or instrumental systems are authorized for inspection use by IAEA. The global summary of IAEA safeguard statistics for 1992 is shown. Also field instrumentation use is shown. The Agency is in the transitional mode for optical surveillance from films to CCTV units. One-time use seals are predominantly employed, but the use of in-situ verifiable seals is increasing. It is noted that instrumentation has become an essential tool for safeguard effectiveness. Instrumentation is generally 'dumb' in the sense that it provides inspectors with specific information that must be interpreted and integrated with other data before drawing safeguard conclusion. The positive features of in-situ instrumentation are shown. A prime example of in-situ instruments is core discharge monitor. Also high count rate gamma spectrometry system and improved Cerenkov viewing device are described. As the equipment carried by inspectors to facilities, miniature CdTe detector probe is shown. Safeguard instrumentation needs for future and the instrumentation activities presently underway are described. (K.I.)

    The response of a borehole strain meter to hydrostatic and shear deformations in an isotropic medium is calculated to facilitate optimum instrument design and produce instrument response factors for parameters typically encountered in installed instruments. Results for an empty borehole are first compared with results for an instrument in intimate contact with the surrounding rock. The effects of the grout used to install the instrument are then examined. Where possible, analytic forms for the response factors are given. Results for typical installations are then presented in graphical form for optimizing instrument design in an environment of known elastic parameters. Alternatively, the results may be applied in the measurement of unknown strain signals, to correct for instrument response or to provide in-situ estimates of the elastic properties of the environment by examination of observed strain response to known strain signals.

  17. The Choice of Innovation Policy Instruments

    DEFF Research Database (Denmark)

    Borrás, Susana; Edquist, Charles

    2013-01-01

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

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

    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.

    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.

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

    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.

  7. Laboratory radiochemical and instrumental methods

    International Nuclear Information System (INIS)

    During the past 10 yr, the basic radiological laboratory support requirements had to be responsive to a number of industrial and regulatory concerns. In the latter part of the 1970s, the US Nuclear Regulatory Commission (NRC) issued generic radiological effluent technical specifications (10CFR50 Appendix I), which provided guidance on the minimum acceptable environmental radiation surveillance program requirements for the nuclear power industry. In the early 1980s, the Environmental Protection Agency (EPA) issued Radioactivity in Drinking Water Standards, and instituted a certification program for state and commercial laboratory processors, providing radioanalytical services in support of the EPA standard. In late December 1982, the NRC issued specific requirements (10CFR61) for licensing land disposal of low-level radioactive wastes containing licensed material. The presentation provides an overview of the typical radiochemical procedures and radiation detection instrumentation employed to process the various media and quantitate the radionuclides associated with the aforementioned programs

  8. Optimal calibration of nuclear instrumentation

    International Nuclear Information System (INIS)

    Accurate knowledge of core power level is essential for the safe and efficient operation of nuclear power plants. Ionization chambers located outside the reactor core have the necessary reliability and response time characteristics and have been used extensively to indicate power level. The calibration of the ion chamber, and associated nuclear instrumentation (NI), has traditionally been based on the thermal power in the secondary coolant system. The usual NI calibration procedure consists of establishing steady-state operating conditions, calorimetrically determining the power at the secondary side of the steam generator, and adjusting the NI output to correspond to the measured thermal power. This study addresses certain questions including; (a) what sampling rate should be employed, (b) how many measurements are required, and (c) how can additional power level related information such as primary coolant loop measurements and knowledge of plant dynamics be included in the calibration procedure

    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.

    Though the primary role of lasers in urology has always been in the treatment of urolithiasis, there are several other indications for their use. There are many different types of lasers currently available, each with unique properties conducive to treating certain disorders. As such, it is critical that today's urologist understands each laser's characteristics in order to optimize patient selection and treatment. The lasers which are primarily used in urologic applications include the carbon dioxide (CO2) laser; the Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG); the Potassium Titanyl Phosphate (KTP) laser and the Holmium:YAG (Ho:YAG) laser. This review focuses on the unique characteristics of each of these lasers as well as the instrumentation needed utilize and deploy these tools in the urinary tract. PMID:19140577

    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.

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

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

    Time-to-science is an important figure of merit for digital instrumentation serving the astronomical community. A digital signal processing (DSP) community is forming that uses shared hardware development, signal processing libraries, and instrument architectures to reduce development time of digital instrumentation and to improve time-to-science for a wide variety of projects. We suggest prioritizing technological development supporting the needs of this nascent DSP community. After outlining several instrument classes that are relying on digital instrumentation development to achieve new science objectives, we identify key areas where technologies pertaining to interoperability and processing flexibility will reduce the time, risk, and cost of developing the digital instrumentation for radio astronomy. These areas represent focus points where support of general-purpose, open-source development for a DSP community should be prioritized in the next decade. Contributors to such technological development may be...

    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.

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

  15. Electronic instrumentation for smart structures

    Blanar, George J.

    1995-04-01

    The requirements of electronic instrumentation for smart structures are similar to those of data acquisition systems at our national particle physics laboratories. Modern high energy and heavy ion physics experiments may have tens of thousands of channels of data sources producing data that must be converted to digital form, compacted, stored and interpreted. In parallel, multiple sensors distributed in and around smart structures generate either binary or analog signals that are voltage, charge, or time like in their information content. In all cases, they must be transmitted, converted and preserved into a unified digital format for real-time processing. This paper will review the current status of practical large scale electronic measurement systems with special attention to architectures and physical organization. Brief surveys of the current state of the art will include preamplifiers and amplifiers, comparators and discriminators, voltage or charge analog-to-digital converters, time internal meters or time-to-digital converters, and finally, counting or scalar systems. The paper will conclude by integrating all of these ideas in a concept for an all-digital readout of a smart structure using the latest techniques used in physics research today.

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

    Nagai, T; Sleege, G; Petry, D

    2007-01-01

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

    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.

  19. Optical infrared sky survey instrumentation

    Craine, E. R.

    1979-01-01

    An unusual, highly modified, Baker reflector-corrector class telescope has been adapted for wide field survey photography in the near infrared. This optical system uses a full field corrector plate and a field flattening lens to provide a flat field subtending about 4.5 deg on the sky. The small aperture telescope (20 inch primary) has been modified for use in the Newtonian focus configuration while preserving the optical elements of the Prime focus configuration. The telescope has been further modified to accept a very large format (146mm diameter photocathode) image intensifier camera to serve as a detector. The camera output is recorded photographically on film rather than glass plates. This unique instrument system is used in a program of sky survey photography in the optical infrared (8000-9000A bandpass) supplemented by visual bandpass photography. The photographs obtained with this system are of value not only for the extreme redness of the band but also because of their high resolution and their freedom from hydrogen emission.

    International Nuclear Information System (INIS)

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

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

  2. Forward instrumentation for ILC detectors

    International Nuclear Information System (INIS)

    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.)

    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.

  5. Tokamak x ray diagnostic instrumentation

    International Nuclear Information System (INIS)

    Three classes of x-ray diagnostic instruments enable measurement of a variety of tokamak physics parameters from different features of the x-ray emission spectrum. (1) The soft x-ray (1 to 50 keV) pulse-height-analysis (PHA) diagnostic measures impurity concentrations from characteristic line intensities and the continuum enhancement, and measures the electron temperature from the continuum slope. (2) The Bragg x-ray crystal spectrometer (XCS) measures the ion temperature and neutral-beam-induced toroidal rotation velocity from the Doppler broadening and wavelength shift, respectively, of spectral lines of medium-Z impurity ions. Impurity charge state distributions, precise wavelengths, and inner-shell excitation and recombination rates can also be studied. X rays are diffracted and focused by a bent crystal onto a position-sensitive detector. The spectral resolving power E/ΔE is greater than 104 and time resolution is 10 ms. (3) The x-ray imaging system (XIS) measures the spatial structure of rapid fluctuations (0.1 to 100 kHZ) providing information on MHD phenomena, impurity transport rates, toroidal rotation velocity, plasma position, and the electron temperature profile. It uses an array of silicon surface-barrier diodes which view different chords of the plasma through a common slot aperture and operate in current (as opposed to counting) mode. The effectiveness of shields to protect detectors from fusion-neutron radiation effects has been studied both theoretically and experimentally

  6. Fixed type incore instrumentation system

    International Nuclear Information System (INIS)

    The present invention concerns a fixed type incore instrumentation system for use in BWR type reactor. A sensitivity ratio of an axially disposed gamma thermometer detection portions is determined based on output signals when the heater incorporated in the gamma thermometer generates heat or when it does not generate heat, and the ratio of gamma heat generation amount of the detection portions is determined based on the above-mentioned sensitivity ratio. The absolute value of the gamma heat generation amount is determine so as to agree with radial components of the power distribution of the reactor core obtained using a physical model of the reactor core, and also determined so as to correspond to the output distribution just after disposing neutron detectors. It is monitored whether the change of the sensitivity ratio of the gamma thermometer detection portions is uniform for detection portions in axial direction or it is increased only in a certain detection portion to judge failure of incorporated heater or that of sensors. The detection portion as a standard of the sensitivity ratio is adapted to have the maximum output signal in the axial direction so as to minimize the error of output signals. (N.H.)

  8. Instruments for subsurface monitoring of geothermal subsidence

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

    1979-07-01

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

    Instrumented hip implants were proposed as a method to monitor and predict the biomechanical and thermal environment surrounding such implants. Nowadays, they are being developed as active implants with the ability to prevent failures by loosening. The generation of electric energy to power active mechanisms of instrumented hip implants remains a question. Instrumented implants cannot be implemented without effective electric power systems. This paper surveys the power supply systems of seventeen implant architectures already implanted in-vivo, namely from instrumented hip joint replacements and instrumented fracture stabilizers. Only inductive power links and batteries were used in-vivo to power the implants. The energy harvesting systems, which were already designed to power instrumented hip implants, were also analyzed focusing their potential to overcome the disadvantages of both inductive-based and battery-based power supply systems. From comparative and critical analyses of the methods to power instrumented implants, one can conclude that: inductive powering and batteries constrain the full operation of instrumented implants; motion-driven electromagnetic energy harvesting is a promising method to power instrumented passive and active hip implants.

    Verification of the geolocation assigned to individual ground pixels as measured by the Ozone Monitoring Instrument (OMI) aboard the NASA EOS-Aura satellite was performed by comparing geophysical Earth surface details as observed in OMI false color images with the high-resolution continental outline vector map as provided by the Interactive Data Language (IDL) software tool from ITT Visual Information Solutions. The OMI false color images are generated from the OMI visible channel by integration over 20-nm-wide spectral bands of the Earth radiance intensity around 484 nm, 420 nm, and 360 nm wavelength per ground pixel. Proportional to the integrated intensity, we assign color values composed of CRT standard red, green, and blue to the OMI ground pixels. Earth surface details studied are mostly high-contrast coast lines where arid land or desert meets deep blue ocean. The IDL high-resolution vector map is based on the 1993 CIA World Database II Map with a 1-km accuracy. Our results indicate that the average OMI geolocation offset over the years 2005-2006 is 0.79 km in latitude and 0.29 km in longitude, with a standard deviation of 1.64 km in latitude and 2.04 km in longitude, respectively. Relative to the OMI nadir pixel size, one obtains mean displacements of ˜6.1% in latitude and ˜1.2% in longitude, with standard deviations of 12.6% and 7.9%, respectively. We conclude that the geolocation assigned to individual OMI ground pixels is sufficiently accurate to support scientific studies of atmospheric features as observed in OMI level 2 satellite data products, such as air quality issues on urban scales or volcanic eruptions and its plumes, that occur on spatial scales comparable to or smaller than OMI nadir pixels.

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

    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.

    Two public policy concepts - modernization of governance and environmental policy integration - serve as the basis for this work. The author links them up with environmental communication (EC) as an integration instrument approach, and tests application at the local level in Latvia. Totally 30 case studies were analysed and survey methods used to interview over 70 people. The article verifies driving forces affecting the internal and external integration of environmental policy, explicates EC instrumentality for integration by assessing policy instruments and stakeholders. The final conclusions affirm that, in order to integrate environmental management into municipal development, it is necessary to establish a complementary set of policy instruments, what might be enabled by wise use of all EC components in their interactivity. The complementarity of EC instruments and stakeholder group efforts forms synergy and enhances better environmental policy integration.

  17. Intonation and Compensation of Fretted String Instruments

    CERN Document Server

    Varieschi, Gabriele U

    2009-01-01

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

    Retrospective and prospective studies were used to assess the numbers, types and persistence of microbes that contaminate wind instruments. All previously played instruments (n = 20) harbored viable bacteria as well as mold and/or yeast. Reedinstruments consistently carried higher microbial loads than did flutes or trumpets. Instruments played within the previous three days bore typical mouth flora, while bacteria recovered after 72 h following play consisted of normal environmental flora. Prospective studies tested survival of potentially pathogenic bacteria (Staphylococcus, Streptococcus, Moraxella, Escherichia coli and attenuated Mycobacterium tuberculosis) when applied to reeds or following simulated 'play' of a clarinet. All species survived for a maximum of 24-48 h on reeds, except Mycobacterium, which persisted through 13 days. In simulated play experiments, test bacteria could persist for up to five days. These findings support the establishment of guidelines for decontamination of wind instruments and for sharing or transfer of these instruments among players. PMID:21745020

  19. Health physics instrumentation - a progress report

    International Nuclear Information System (INIS)

    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'.

    2009-08-01

    The relationship between psychopathy and violence is well established. However, the extent to which psychopathy is related to different types of violent behavior warrants further study. We examined the relationship between instrumental violence, psychopathy, and psychopathic traits among 248 European American and African American adult male county jail inmates. We assessed instrumentality based on subjective motivations for respondent-identified acts of violence. Psychopathy was assessed using the PCL-R based on interview and file review. We controlled for potentially important covariates, namely IQ and prior violence. Results were in part consistent with findings from studies with adolescents, in that we identified a positive relationship between instrumentality of violence and manipulative interpersonal style. Results differed from youth studies with regard to relationships between instrumentality and other facets of psychopathy. The implications of our study are discussed with regard to treatment and the developmental stability of the relationship between psychopathic traits and instrumental violence. PMID:19663661

  2. The nonlinear physics of musical instruments

    Fletcher, N. H.

    1999-05-01

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

    2013-01-01

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

  5. Intraoral Pressure in Ethnic Wind Instruments

    2013-01-01

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

    This study aimed to evaluate effects of torsional loading on the mechanical properties of endodontic instruments using the nanoindentation technique. ProFile (PF; size 30, taper 04; Dentsply Maillefer, Switzerland) and stainless steel (SS; size 30, taper 02; Mani, Japan) instruments were subjected to torsional test. Nanoindentation was then performed adjacent to the edge of fracture (edge) and at the cutting part beside the shank (shank). Hardness and elastic modulus were measured under 100-mN force on 100 locations at each region, and compared to those obtained from the same regions on new instruments. It showed that PF and SS instruments failed at 559 ± 67 and 596 ± 73 rotation degrees and mean maximum torque of 0.90 ± 0.07 and 0.99 ± 0.05 N-cm, respectively. Hardness and elastic modulus ranged 4.8-6.7 and 118-339 GPa in SS, and 2.7-3.2 and 52-81 GPa in PF. Significant differences between torsion-fractured and new instruments in hardness and elastic modulus were detected in the SS system used. While in PF system, the edge region after torsional fracture had significantly lower hardness and elastic modulus compared to new instruments. The local hardness and modulus of elasticity of endodontic instruments adjacent to the fracture edge are significantly reduced by torsional loading. PMID:24610598

  7. Instrument systems for environmental radiation and radioactivity

    International Nuclear Information System (INIS)

    Assessment of impact of low level radiation calls for development of techniques and instrumentation for dosimetric purposes. The specifications for such instruments are quite stringent since these have to be operated in a hostile environment on a real time basis often requiring to meet very low sensitivities. Though the basic measurement systems may seem rudimentary in some cases, the automation and refinement required to meet the specifications pose challenges. The challenges have been met successfully to a large extent. The paper describes the indigenous development of various instruments for measurement of environmental radiation and radioactivity.

    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.

    Full Text Available INTRODUÇÃO: A avaliação da taxa de prevalência de transtornos mentais na infância e adolescência contribui para o aumento do conhecimento de sua distribuição numa dada população e fornece dados para o planejamento, execução e avaliação dos serviços de saúde. Objetivou-se avaliar queixas referidas a "problemas dos nervos" na população de 1 a 19 anos, como forma de aproximação à questão da prevalência da doença mental nessa faixa etária. MÉTODOS: Foi estudado um grupo de 141 crianças e adolescentes com queixas referidas a "problemas dos nervos" a partir de um levantamento populacional realizado numa amostra de 3.158 indivíduos, residentes na região sudoeste da Grande São Paulo, de julho de 1989 a julho 1990. Foram analisados: tipos de queixas, causas referidas, idade, sexo e conduta. RESULTADOS: A prevalência obtida foi de 4,7%. Houve crescimento das queixas com o aumento da idade, predomínio do sexo masculino nos mais jovens e do feminino a partir dos 14 anos. A busca de ajuda foi referida em 22,6% dos casos e o preditor mais importante foi a gravidade da queixa. CONCLUSÕES: A taxa de prevalência encontrada referiu-se à capacidade de reconhecimento dos transtornos mentais pela população, refletindo a representação que a família tem destes problemas. Foi encontrada baixa procura de atendimento; foram apontadas as possíveis causas e discutidos mecanismos possíveis de intervenção para o resgate da necessidade não atendida.INTRODUCTION: Determining the prevalence of mental disturbances in childhood and adolescence gives us a better knowledge of their distribution in a given age group and provide us data for planning, implementing and evaluating health care programs.

    Full Text Available Este trabalho teve como objetivos desenvolver e testar um algoritmo com base na metaheurística busca tabu (BT, para a solução de problemas de gerenciamento florestal com restrições de inteireza. Os problemas avaliados tinham entre 93 e 423 variáveis de decisão, sujeitos às restrições de singularidade, produção mínima e produção máxima periódicas. Todos os problemas tiveram como objetivo a maximização do valor presente líquido. O algoritmo para implementação da BT foi codificado em ambiente delphi 5.0 e os testes foram efetuados em um microcomputador AMD K6II 500 MHZ, com memória RAM de 64 MB e disco rígido de 15GB. O desempenho da BT foi avaliado de acordo com as medidas de eficácia e eficiência. Os diferentes valores ou categorias dos parâmetros da BT foram testados e comparados quanto aos seus efeitos na eficácia do algoritmo. A seleção da melhor configuração de parâmetros foi feita com o teste L&O, a 1% de probabilidade, e as análises através de estatísticas descritivas. A melhor configuração de parâmetros propiciou à BT eficácia média de 95,97%, valor mínimo igual a 90,39% e valor máximo igual a 98,84%, com um coeficiente de variação de 2,48% do ótimo matemático. Para o problema de maior porte, a eficiência da BT foi duas vezes superior à eficiência do algoritmo exato branch and bound, apresentando-se como uma abordagem muito atrativa para solução de importantes problemas de gerenciamento florestal.This work aimed to develop and test an algorithm based on Tabu Search (TS metaheuristics; to solve problems of forest management with integer constraints.

    Full Text Available Há algumas décadas, busca-se compreender melhor o processo subjacente ao comportamento de procura de tratamento por usuários que fazem uso nocivo ou são dependentes de substâncias psicoativas. Os modelos atualmente propostos baseiam-se principalmente na análise epidemiológica de certas características individuais quanto ao poder que têm de influenciar esse comportamento de disposição para tratamento. OBJETIVOS: Interpretar e compreender possíveis significados pessoais associados a alterações psicopatológicas, sobre como podem se relacionar à procura de tratamento, na visão dos próprios pacientes. MÉTODO: Pesquisa qualitativa com entrevistas semidirigidas com amostra intencional de 13 dependentes de substâncias que procuraram tratamento. RESULTADOS: Houve relatos espontâneos de alterações de forma, curso e conteúdo de pensamento e juízo de realidade, alterações de sensopercepção, de atenção, memória e linguagem. Os membros da amostra pareceram relacioná-las à motivação para tratamento. Os dados foram interpretados considerando o contexto psicocultural dos entrevistados e seus quadros clínicos de síndrome de dependência, de abstinência e de comorbidade. CONCLUSÕES: Pesquisas qualitativas contribuem para aprimorar os modelos explicativos sobre procura de tratamento por dependentes de substâncias. Investigar clinicamente alterações psicopatológicas parece poder contribuir para motivar pacientes para tratamentos específicos do uso disfuncional de substâncias.During the last few decades it is aimed to better understand the process underlying treatment seeking behavior by harmful or dependent psychoactive substances users. The currently proposed models are mainly based on the epidemiological analysis of certain number of individual characteristics, as they have the power to influence this behavior of readiness for treatment. OBJECTIVES: To interpret and understand possible personal meanings associated with

  13. Cryogenic Detectors (Narrow Field Instruments)

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

  14. The Journey to Fielded BioInstrumentation

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

  15. Carbon foils for space plasma instrumentation

    Carbon foils have been successfully used for several decades in space plasma instruments to detect ions and neutral atoms. These instruments take advantage of two properties of the particle-foil interaction: charge conversion of neutral atoms and/or secondary electron emission. This interaction also creates several adverse effects for the projectile exiting the foil, such as angular scattering and energy straggling, which usually act to reduce the sensitivity and overall performance of an instrument. The magnitude of these effects mainly varies with the incident angle, energy, and mass of the incoming projectile and the foil thickness. In this paper, we describe these effects and the properties of the interaction. We also summarize results from recent studies with graphene foils, which can be made thinner than carbon foils due to their superior strength. Graphene foils may soon replace carbon foils in space plasma instruments and open new opportunities for space research in the future.
