    1998-02-01

    Full Text Available RESUMEN   Cuando las organizaciones se configuran y definen sus objetivos, definen también el sistema interno de interacción social y las relaciones sociales que les van a servir para cumplir con sus objetivos, que son la función social de la organización empresarial. El sistema que adoptan es estructurado con una racionalidad predeterminada. Esto quiere decir que quienes han pensado en esta actividad, han elaborado un conjunto de concepciones, creencias y percepciones, sobre las características del mercado, la relación con otras instituciones y la forma como se valora el ser humano. Con base en los criterios y valores de los fundadores de la organización se considera, así mismo, si quiénes colaboran son únicamente unidades productivas o por el contrario talentos humanos. Dependiendo de los valores que se adopten, las organizaciones asumen dos formas de racionalidad en las organizaciones: una racionalidad instrumental teleológica, dirigida hacia el logro de los objetivos o una racionalidad comunicativa constructivista que apunta hacia los fines de la organización

    Full Text Available Este trabalho de cunho qualitativo se propôs compreender como se entrelaçam as racionalidades substantiva e instrumental no cotidiano dos gestores de primeira linha de uma multinacional e alguns funcionários de alto escalão de um órgão público na região do quadrilátero ferrífero em Minas Gerais. A coleta de dados ocorreu por meio da entrevista semiestruturada, que foram gravadas, transcritas e posteriormente analisadas via Análise de Conteúdo de Bardin (2006. A base teórica que fomentou as análises foram os trabalhos de Guerreiro Ramos (1981 e Maurício Serva (1996. Diante disso foi possível identificar 11 rubricas previstas por Serva (1996, entendidas nas análises como unidades de sentido; estas foram classificadas por proporção conforme sua aparição nos relatos; são elas: valores e objetivos, satisfação individual, reflexão, controle, tomada de decisão, divisão do trabalho, hierarquia e normas, conflito, ação social, relações interpessoais e dimensão simbólica. A presença da racionalidade instrumental ainda é latente no cotidiano analisado, sendo necessária alguma evolução para que esse modelo reificado do ser humano se altere. Todavia, tal pesquisa se mostra relevante, pois permitiu verificar uma manifestação considerável da racionalidade substantiva em um ambiente supostamente instrumental.   This qualitative study was proposed to understand how the substantive and instrumental rationalities are interwoven in the daily life of first-line managers of a multinational and some high-ranking officials from a public agency in the iron quadrilateral region of Minas Gerais. The data were collected through semi-structured interviews, which were recorded, transcribed and analyzed through Bardin Content Analysis (2006. A theoretical basis that fostered as analyzes were the works of Guerreiro Ramos (1981 and Maurício Serva (1996. Thus, it was possible to identify 11 items predicted by Serva (1996, understood in

    Carlos Alberto Mourthé Junior

    2017-12-01

    Full Text Available Sustentado em uma prática educacional construtivista, dialógica e baseada em competência, este artigo discute uma tradição racionalista/objetivista de ensino-aprendizagem. Expressões artísticas, especialmente cinematográficas, são apresentadas como disparadores educacionais. Educandos organizados em pequenos grupos compartilham, correlacionam e conversam sobre suas emoções, possibilitando uma melhor compreensão das racionalidades envolvidas no processo de aprendizagem. Como os grupos apresentam diferentes estágios de problematização das emoções, propomos categorias para apoiar docentes e integrantes na identificação da natureza conversacional dos grupos, favorecendo suas intervenções e contribuições para o desenvolvimento individual e social dos participantes, com referência a um perfil de competência.

    Eugênio Ávila Pedrozo

    2008-04-01

    Full Text Available Com base na premissa de que a tomada de decisão é um processo lógico, fruto da inteligência e racionalidade humana, objetiva-se com esse trabalho verificar se os agricultores orgânicos cooperados da Ecocitrus, ao decidirem pelo cultivo orgânico, estavam mais inclinados a uma motivação substantiva ou instrumental e, por conseguinte, se a cooperativa pode ser considerada hoje uma organização substantiva ou não. Este artigo baseou-se no modelo de aplicação teórica sobre racionalidade de Mauricio Serva (1993, 1997 e na proposta de organizações substantivas de Guerreiro Ramos (1989. O método utilizado é essencialmente qualitativo, com caráter exploratório-descritivo. Os sujeitos da pesquisa são produtores de bergamota orgânica, cooperados da Ecocitrus. Os dados foram levantados em julho e agosto de 2005, por meio de entrevistas semi-estruturadas e aplicação de questionários fechados. Por fim, os resultados permitiram caracterizar a Ecocitrus como uma organização substantiva de intensidade elevada.

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available The debates about rationality and its concepts are classical in management studies. Nevertheless, research on the meanings attributed to work, from psychology, are from the 1970s. When studying the meanings of work, authors have not referred to the issue of instrumental and substantive rationality, but have prioritized the identification of that which characterizes work with meaning/sense. In this theoretical essay, the presumption is that the meanings attributed to work are related to the types of rationality present in society and work organizations. As such, the aim is to identify approximations between the features that characterize the meanings attributed to work and instrumental and substantive rationality. Elements that describe the meanings of work are presented, based on psychological references and focusing on research by Morin (1996, 2001; as well as studies that characterize the constitutive features of instrumental and substantive rationality, traditionally studied in management, with emphasis on Serva (1993, 1996, 1997a, 1997b. This possible articulation allowed for the development of work meaning/sense conception of the instrumental type and work meaning/sense of the substantive type; highlighting that there is an overlap between both types of senses in organizations.

  7. A flexibilização do trabalho e da gestão de pessoas limitadas pela racionalidade instrumental

    Directory of Open Access Journals (Sweden)

    Clesar Luiz Loch

    2004-01-01

    Full Text Available This essay aims to discuss the flexibility of work and the people’s management in a context that prevails the instrumental rationality, proper from the enterprises. The work can take positive connotations like its emancipating and transforming character, as it can takes its opposite: alienation and suffering. In the Capitalism, work is organized according to the interests of those who have capital. The people’s management is in tune with the changes in today’s capitalist economy and becomes more flexible through innovative practices, which intend to restore the subjectivity of human nature. This flexibility develops within a context in which the instrumental rationality prevails. It is believed that the people’s management, when based on a substantive view and characterized by an ethical code of conduct, with important values, tends to improve the participation of the workers. In this case, work itself could be able to develop the human potential and assume a creative, transforming and emancipating character.

  10. EMPREENDEDORISMO E RACIONALIDADE

    Directory of Open Access Journals (Sweden)

    Geraldo Magela Rodrigues Vasconcelos

    2011-12-01

    Full Text Available O fenômeno do empreendedorismo tem sido tema relevante na ciência econômica, com repercussão em outras ciências, que procuram esclarecer qual efetivamente o papel desempenhado pelo empreendedor no desenvolvimento social. Os estudos procuram esclarecer como este indivíduo opera a partir do ponto de vista da criação de negócios, da identificação de oportunidades e da busca do lucro, e também do ponto vista pessoal, em termos de processo de decisão e de escolhas, e seus mecanismos. Este artigo apresenta uma breve discussão dos motivos que levaram os autores neoclássicos a “abandonarem” a figura do empreendedor, o que transformou-se no principal debate entre os neoclássicos e seus críticos, especialmente Schumpeter. Posteriormente, destaca o contexto decisório em que o empreendedor opera, tanto do ponto de vista pessoal, quanto do ambiente em que trabalha. Finalizando, discute a questão da racionalidade nesse processo, apresentando as considerações finais e questões para discussão e estudo.

  11. APONTAMENTOS PARA CONSTRUÇÃO DA RACIONALIDADE AMBIENTAL

    Directory of Open Access Journals (Sweden)

    Munir Jorge Felício

    2015-12-01

    Full Text Available Os apontamentos para construção da racionalidade ambiental propostos nesse texto foram reunidos das contribuições presentes nas análises da fenomenologia, da epistemologia e da ontologia do ser social em Marx. Essa iniciativa almeja ampliar e aprofundar a compreensão da problemática ambiental cujas mudanças globais provocam desafios principalmente para comunidade científica. Trata-se de problematizar o desenvolvimento da racionalidade econômica, a partir das degradações dos recursos naturais engendradas pelo atual avanço do modelo de desenvolvimento socioeconômico. Modelo que se baseia na majoração da produtividade, se apóia na expansão tecnológica e se sustenta da exploração como se os recursos naturais fossem ainda considerados abundantes e ilimitados. A transição dessa racionalidade econômica para a racionalidade ambiental é um empreendimento buscado pelas possibilidades de conhecimento advindo das análises da fenomenologia. Entre essas possibilidades, a interdisciplinaridade indicada como necessária pela epistemologia ambiental, pode se tornar uma interessante estratégia de pesquisa, desde que, tenha como ponto de partida, as demandas externas onde se encontram os elementos da atual questão ambiental e de seus desdobramentos.

  12. A perspectiva pragmática nas pesquisas sobre prática instrumental: condições e implicações procedimentais A pragmatic perspective in instrumental practice research: conditions and procedural implications

    Directory of Open Access Journals (Sweden)

    Regina Antunes Teixeira dos Santos

    2009-01-01

    Full Text Available Pesquisas em prática instrumental evidenciam tendências que expressam certos aspectos de racionalidade calculada da ação e apontam para uma perspectiva pragmática de engajamento pessoal frente às situações de prática. Sistematizações sobre modos intencionais de proceder na prática instrumental em conexão com níveis de especialização músico-instrumental encontram-se não somente nos resultados dessas pesquisas, mas também implícitos nos conceitos de prática. Assim, o presente artigo discute a natureza e a finalidade das condições procedimentais implícitas nos conceitos e resultados de pesquisas em prática instrumental. Implicações procedimentais apresentam-se também nas discussões referentes à quantidade e a qualidade na prática, e justificam a existência de níveis diferenciados de especialização músico-instrumental na prática. O presente artigo aborda ainda a relação entre procedimentos e estratégias de prática.Research in instrumental practice has shown some trends that express certain aspects of calculated rationality, and point out to a pragmatic regime of personal commitment during practice. The systematization of the intentional procedures of the performer in order to improve and to refine one's music expertise level is present in research as well as in the concepts of instrumental practice. Thus, the present article discusses the nature and the goals of the procedimental conditions implicit in the concepts and research results in instrumental practice. Procedimental implications are also present in the discussion of the role of quantity and quality in the practice and justify the existence of different levels of instrumental expertise in the practice. This article also raises the relationship between procedures and strategies of practice.

    2000-01-01

    Full Text Available En este trabajo se discute acerca de la distinción entre razón y racionalidad, pues se le ha colmado con prejuicios, imaginarios y mitos. Sin embargo, la comprensión del concepto de racionalidad lleva a la interpretación moderna del mundo y debido a la conexión entre teoría de la racionalidad y de la modernidad se puede construir una teoría de la sociedad. Para el análisis se recuperan aquellos autores que han enfatizado la ponencia crítica de la razón, para cuestionar como plantea Habermas las aporías de la razón y reivindicar el proyecto emancipador de la propia razón, rescatar el mundo de la vida de la racionalidad instrumental para crear la posibilidad de una sociedad verdaderamente humana.

  14. Al rescate de la racionalidad

    Directory of Open Access Journals (Sweden)

    Gabriel Costantino

    2004-01-01

    Full Text Available Es un lugar común en la historia del pensamiento ubicar el origen de la racionalidad cerca del siglo VI a. C., en las zonas de influencia griega. Muchos trabajos ilustrados se han realizado sobre este acontecimiento, su relación con el pensamiento mítico, la solidaridad con la estructura institucional de la polis, sus características distintivas, etc. En este artículo se analizan algunos de esos debates en torno a esa idea de racionalidad nacida hace más de 2500 años. En este sentido, volver a La Tradición configurada por Sócrates, Platón y Aristóteles, nos puede decir mucho acerca de diferentes planteamientos modernos y contemporáneos; de la Ilustración a Jürgen Habermas, de los derechos humanos a John Rawls y Ronald Dworkin, las razones e ideales de La Tradición se vuelven a presentar, e iluminan lo que está puesto en juego.

  15. Sobre o estatuto epistemológico da racionalidade econômica segundo Karl Popper

    Directory of Open Access Journals (Sweden)

    Brena Paula Magno Fernandez

    2014-12-01

    Full Text Available Três tipos de críticas são comumente levantadas contra a utilização do postulado da racionalidade na ciência econômica. A primeira delas associa-se ao argumento da circularidade, a segunda diz respeito à blindagem da teoria contra a refutação e a terceira - e mais importante delas - refere-se à inadequação empírica. O presente artigo busca encaminhar esta última, à luz do tratamento dado por Popper ao longo de sua carreira para a questão de qual seria o estatuto epistemológico do princípio da racionalidade nas teorias econômicas. Três possíveis respostas a esta questão são aqui examinadas, explicitando-se suas respectivas estruturas lógicas. A primeira delas propõe que o postulado da racionalidade desempenhe o papel de lei geral do comportamento humano. A segunda requer que ele funcione como um axioma da teoria. Finalmente, a terceira proposta sugere que o postulado da racionalidade seja entendido como regra metodológica. Conclui-se o artigo sugerindo que esta última solução satisfaz ao apelo que o tipo de crítica aqui examinada faz ao conceito de racionalidade. Não obstante, ao situar-se no contexto metateórico, o postulado da racionalidade mantém importância inegável na teoria econômica. Sem ele, não se disporia de instrumentos que conduzissem à seleção de dados empíricos voltados ao teste das teorias.

  16. Mercados e racionalidades: a perspectiva de Alberto Guerreiro Ramos e Cornelius Castoriadis

    Directory of Open Access Journals (Sweden)

    Manoel Fernandes Nery

    Full Text Available Mercados e racionalidades são duas categorias das Ciências Sociais bastante discutidas na academia. Considera-se Max Weber um dos pioneiros no estudo da categoria racionalidades, da qual teria se originado grande parte das interpretações dominantes nas Ciências Sociais, em particular da Sociologia. Os autores que descrevem o mercado enfatizam diferentes aspectos, e os relatos sobre seu aparecimento histórico são também divergentes. Não existe, portanto, nas Ciências Sociais, uma interpretação única sobre as funções e a historicidade do mercado, bem como não há unanimidade em relação às formas de racionalidades dominantes. Este ensaio teórico traz a perspectiva de dois autores sobre mercados e racionalidades, sem a intenção de absolutizar seu pensamento ou limitar suas contribuições aos temas. Ramos (1981 concebe a razão como uma força inerente ao indivíduo, a qual denomina razão substantiva, assinalando que, com Thomas Hobbes, a razão configura um cálculo utilitário de consequências. Adicionalmente, Ramos (1981 vê o mercado como uma ameaça à liberdade e autonomia dos indivíduos. Para Castoriadis (1992b, 1996, 1999b, a razão está presente em um coletivo social anônimo, sendo homem e sociedade inseparáveis do contexto sócio-histórico. Já o mercado, bem ou mal, funciona, apesar da manipulação dos consumidores e da violência contra os trabalhadores. Em comum, os autores defendem a liberdade e a autonomia dos indivíduos. Conclui-se o ensaio corroborando a visão de Alves (2007, pois as elucidações apresentadas ao longo do texto indicam que as divergências não estão nas teorias e nos métodos, mas na natureza do objeto estudado.

    Directory of Open Access Journals (Sweden)

    Silvia Maria de Araújo

    2006-08-01

    Full Text Available A condução da vida por uma racionalidade capitalista-instrumental é o tema aqui discutido sob o prisma de reconhecê-la em manifestações da vida, sem desconhecer o quanto afeta o chamado mundo do trabalho. A subjetividade comprometida do trabalhador nesse processo é um dos seus maiores efeitos. A construção do texto resgata as idéias weberianas sobre um processo racional-instrumental que absorve a vida moderna, apresentando, em seguida, o novo paradigma habermasiano da razão comunicativa como alternativa às conseqüências dessa lógica tipicamente capitalista. Ao analisar a invasão do mundo sistêmico sobre o mundo da vida e a continuidade desse processo, o artigo elabora uma reflexão sobre a racionalidade, colocando a indagação: nas condições da moderna produção flexível, marca das grandes e médias indústrias de caráter transnacional, está-se diante de uma racionalidade ou irracionalidade capitalista?The instrumental-capitalist rationality that occupies the world of life is here discussed in a labor’s point of view. The commitment of worker’s subjectivity is one of the biggest results of the technological, technical and scientific transformation occurred in the last century and it is disposed to the capitalist accumulation, moreover after the adoption of the flexible production method. The modern automotive industry assembled in Curitiba, since the beginning of the year 1990, is one of this transitions example. The intense social transformations of the last three decades in the world of work were provoked by the innovations in the labor and production organization area. The text begins with a discussion of Weber ideas about a rational-instrumental process that emerges in modernity, presents Habermas’s communicative paradigm proposition as an alternative to the consequences of this hegemonic logic. Analyzing the advancement of the systemic world over the world of life, this paper builds up a critic to the

  18. Racionalidad y deliberación en la acción colectiva

    Directory of Open Access Journals (Sweden)

    Noguera, José Antonio

    2007-04-01

    Full Text Available The theory of collective action formulated by Mancur Olson in 1965 was based on an instrumental-strategic concept of rationality that has been generally used by standard rational choice theory. Different social theorists (such as Habermas or Elster have tried to challenge this view by defending an alternative concept of rationality based on deliberation or rational argumentation. In this article I discuss to what extent these challenges have been successful in offering a real theoretical alternative to strategic rationality as a mechanism for the production and coordination of collective actions. For that purpose, three questions will be addressed: 1 Is communicative or deliberative rationality conceptually different from strategic rationality? 2 Is it empirically plausible as an explanatory principle for collective actions (and specially for those of social movements? 3 Is it more defensible from a normative point of view?

    La teoría de la acción colectiva, tal y como fue formulada por Mancur Olson en 1965, se basaba en un concepto instrumental-estratégico de la racionalidad que ha sido el habitualmente utilizado en la teoría de la elección racional estándar. Diversos teóricos sociales (como Habermas o Elster han tratado de desafiar esta concepción postulando un concepto alternativo de racionalidad que se base en la deliberación o la argumentación racional. En este artículo se discute hasta qué punto tales intentos han tenido éxito a la hora de ofrecer una alternativa teórica real a la racionalidad estratégica como mecanismo de generación y coordinación de las acciones colectivas. Para ello se plantearán tres cuestiones: 1 ¿Es la racionalidad comunicativa o deliberativa conceptualmente diferente de la racionalidad estratégica? 2 ¿Es empíricamente plausible como principio explicativo de las acciones colectivas, y especialmente de las de los movimientos sociales? 3 ¿Es normativamente más defendible?

    Directory of Open Access Journals (Sweden)

    Jaylson Jair da Silveira

    2003-12-01

    Full Text Available O presente trabalho toma como ponto de partida o modelo macrodinâmico de Richard M. Goodwin, apresentado no clássico artigo “A Growth Cycle” (1967. Neste modelo a interação entre distribuição de renda e acumulação de capital gera um ciclo de crescimento que oscila em torno de uma trajetória de crescimento equilibrado. O objetivo do presente trabalho é investigar a possibilidade de existência de ciclos goodwinianos com heterogeneidade de salários e de taxas de lucro. Essa análise é realizada considerando o processo de concorrência entre trabalhadores num ambiente de racionalidade limitada. Para formalizar o processo de concorrência entre trabalhadores foram utilizados dois recursos: (i a “alegoria das ilhas”, que tem sido amplamente adotada na macroeconomia moderna, a fim de apreender situações de informação imperfeita; e (ii os instrumentos analíticos desenvolvidos pela teoria dos jogos evolucionários aplicada a ambientes sociais. O modelo construído combina o modelo de Goodwin com uma formalização estilizada do fluxo de trabalho como um processo de imitação num ambiente de racionalidade limitada (dinâmica de replicação num contexto social. Neste modelo demonstra-se a possibilidade de o sistema econômico não convergir para um estado de equilíbrio de longo prazo e a possibilidade do sistema econômico convergir para um ciclo goodwiniano caracterizado por heterogeneidade de salários e de taxas de lucro.This paper starts from the macrodynamical model developed by Richard M. Goodwin, which was first shown in the seminal paper “A Growth Cycle” (Goodwin, 1967. In this model it was described an interaction between income-distribution and capital accumulation that generates a growth cycle swinging along a balanced growth path. The objective of this work is to investigate the possibility of existence of goodwinian cycles with heterogeneity in wage and in profit rates. This task is carried out considering the

    Directory of Open Access Journals (Sweden)

    Eda Terezinha de Oliveira Tassara

    Full Text Available Resumo: Este ensaio visa refletir sobre como superar obstáculos que se antepõem à capacidade de pensar de forma racional, a capacidade intelectual que envolve a abstração reflexiva e sua elaboração em correspondente argumentação. Parte da constatação de que, se se observa, de um lado, um crescimento na complexidade lógica do pensamento coloquial verbalizado, de outro, percebe-se uma ausência de competência nas operações intelectuais de análise dos processos racionais a ele subjacentes. Ou seja, a racionalidade contemporânea, alimentada pelos processos e produtos de conhecimento gerados através do pensamento abstrato e dedutivo do campo técnico-científico, comunicar-se-ia com a sociedade de maneira naturalizada, sob forma de representação social e, portanto, eivada de aportes ideológicos, de irracionalidades e/ou racionalizações acríticas. Visa-se refletir, então, sobre como subsidiar a superação de obstáculos à universalização do pleno exercício da razão e/ou da hermenêutica da racionalidade, instrumentalizando contrapontos aos impedimentos gerados pela ignorância ou pelas negatividades ou pelos núcleos dogmáticos do pensamento.

    2016-02-01

    Full Text Available Trata-se de um recorte de tese de doutorado que utilizou o Interacionismo Simbólico como referencial teórico e a Teoria Fundamentada dos Dados como método, para compreender as interpretações e os sentidos atribuídos aos instrumentos utilizados nas ações locais de vigilância sanitária e como eles interferem na identificação do risco e nas escolhas das intervenções. O profissional utiliza um conjunto de referências técnicas, empíricas e instrumentais que lhe permite interpretar as possibilidades de ações e as condições situacionais. Utilizando a legislação sanitária, o conhecimento e a experiência, o profissional identifica e avalia o risco. Estes instrumentos estruturam os saberes e as ações, compondo um processo objetivado racionalmente que utiliza o conhecimento técnico e interpretações críticas, mas que envolve decisões subjetivas baseadas na experiência e nas interpretações. A intervenção é a representação da existência do risco e da ação protetora. É definida em um contexto específico, constituindo um sistema com objetivo de modificar uma situação problemática. Não basta identificar o risco, mas definir como e quais meios podem ser mobilizados para controlá-lo. Intervir constitui-se, portanto, em um desafio científico e político para o profissional. ============================================== This article is part of a doctoral thesis that uses both Symbolic Interactionism as a theoretical framework, and Grounded Theory as a method, to understand the interpretations and meanings attributed to the instruments used in local actions of health surveillance; also to comprehend how these instruments interfere with risk identification and decision-making processes of interventions. The professional uses a set of empirical techniques and instrumental references that allow him to interpret possibilities for actions and situational conditions.

  6. RACIONALIDADE ECONÔMICA, TRABALHO E ECOLOGIA EM ANDRÉ GORZ

    Directory of Open Access Journals (Sweden)

    André Langer

    Full Text Available O presente artigo tem por objetivo apresentar a análise crítica de André Gorz sobre o trabalho e a ecologia política a partir da centralidade que o conceito de racionalidade econômica no capitalismo adquire em seu pensamento. Para ele, a extensão ilimitada da racionalidade econômica ao trabalho e à natureza é considerada sem futuro do ponto de vista da sociedade. Gorz reconhece a íntima relação entre a crítica do capitalismo e a tarefa da ecologia política. Outro aspecto presente em sua obra, menos explorado, é a relação entre trabalho e crise ecológica. O capitalismo apropria-se do trabalho ou emprego não apenas para os seus interesses, mas também os transforma em instrumentos de destruição da natureza. Este paper objetiva também, fiel ao espírito do próprio Gorz, embora de maneira sucinta, indicar alguns horizontes alternativos.

    2002-08-01

    Full Text Available Las amenazas a la vida en el planeta, los hechos que han “asaltado al dogma económico” (Daly y Cobb, 1993 tienen mucho que ver con una doble toma de conciencia en la sociedad contemporánea. La primera, sobre lo restringida y esterilizante que resulta una visión economicista para enfrentar los problemas que más preocupan al ser humano hoy: las heridas infligidas al ecosistema, el aumento de la pobreza y la desigualdad, y el crecimiento desproporcionado de la actividad humana en relación a las posibilidades de la biosfera.La segunda, implicada en la anterior, la de darse cuenta que esa limitación está asociada al concepto de suyo estrecho y parcial de racionalidad económica. Enfrentamos aquí el problema del reduccionismo transmitido en el discurso y en la práctica misma de la disciplina económica que, sin embargo, no es exclusivo de ésta ni es atribuible sólo a deficiencias internas de los profesionales que la practican. Existe toda una larga tradición dentro de la cual se ha ido reduciendo de manera progresiva el concepto de razón humana y se ha ido produciendo ese concepto estrecho de racionalidad del que ahora la humanidad realiza esfuerzos por librarse.

These works reveal enough connections among themselves, so as to be able to assemble them under the common name of “19th Century Brick Architecture”, a name beyond nuances of style characteristic of each region or country. This article analyzes those most significant values of the Brick Architecture which allow it to be understood as a step towards modernity.

    El análisis de las obras de Arquitectura construidas con ladrillo en Europa, entre mediados del siglo XIX y principios del XX, demuestra que explotaban las posibilidades técnicas y formales del material, y seguían la corriente de racionalidad constructiva imperante en los inicios de la era industrial. Estas obras revelan suficientes conexiones entre sí, para poderlas agrupar bajo la denominación común de ''Arquitectura de Ladrillos del siglo XIX", por encima de matices estilísticos propios de cada región o país. En el artículo se analizan aquellos valores más significativos de la Arquitectura de Ladrillos, que permiten entenderla como un paso hacia la modernidad.

    Full Text Available The levels of uncertainty perceived by managers as having the perspective of the theoretical support of the Information Uncertainty, focusing on the multidimensional approach proposed by Milliken (1987, which supports the existence of three types of uncertainty: uncertainty of state, uncertainty effect and response uncertainty. The levels of rationality of managers were estimated to construct a second order from the uncertainties of effect and response uncertainty, with the theoretical support in the definitions of the concept of bounded rationality proposed by Simon (1957. The data collected from the 118 employees of the banking sector in the State of São Paulo were analyzed using Structural Equation Modeling with the Software Smart PLS. The results indicated a significant influence of the state uncertainty on the  level of rationality of managers and bring important methodological and conceptual contributions to the advancement of studies on the subject of uncertainty in decision makingEsta pesquisa foi desenvolvida com o objetivo de avaliar o impacto da incerteza percebida no ambiente sobre os níveis de racionalidade dos gestores do setor financeiro.

    Full Text Available La racionalidad económica es uno de los principales rasgos de la modernidad. Esta racionalidad es, aparentemente, resultado de la ruptura con la vieja superstición religiosa. Sin embargo, sus raíces están en ese mundo religioso, que cree haber superado. en este sentido, el proceso de secularización, del que nace la moderna racionalidad, no es más que la interiorización de los valores religiosos del cristianismo. La creencia de que el individuo, siguiendo sus propios intereses, da lugar a un mundo ordenado, es el rasgo característico de la racionalidad económica. Esta creencia tiene sus raíces en la doctrina cristiana en más de un mundo providencia. El desarrollo de la racionalidad económica no constituye a la superstición religiosa, sino que ella misma, como una nueva forma de superstición, se desarrolla en paralelo con ella.

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

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

Este trabajo parte del análisis de tres movimientos que resisten a proyectos de infraestructura hidroenergética en Chile (Koz Koz, Colombia (Asoquimbo y Argentina (Mesa Provincial No a las Represas. ¿En qué medida estos movimientos sociales proponen una alternativa a la racionalidad instrumental que nos hace maximizadores de utilidad o beneficio? La hipótesis propuesta es que estos movimientos están contribuyendo a la construcción de una racionalidad reproductiva-ambiental, que sitúa en el centro la reproducción ampliada de la vida, y no del capital. Esta investigación se apoya en un extensivo trabajo de campo con entrevistas, observación participativa y con análisis de fuentes primarias y secundarias.

    Full Text Available OBJETIVO: Caracterizar os principais elementos processuais, médico-científicos e sanitários que respaldam as decisões das demandas judiciais individuais por medicamentos consideradas essenciais. MÉTODOS: Estudo descritivo retrospectivo com base em 27 ações julgadas em 2ª instância no Estado do Rio de Janeiro em 2006. Os processos originais foram solicitados ao Arquivo Central do Tribunal de Justiça do Estado do Rio de Janeiro, fotografados e analisados na íntegra. RESULTADOS: Todas as ações incluíram prescrição e atestado médicos. As prescrições estavam em desacordo com a legislação. Não houve perícia médica em nenhuma das ações e em 7,4% constavam exames complementares. Apesar da escassa informação médica contida nos autos, todos os pedidos foram deferidos. CONCLUSÕES: O acolhimento de demandas judiciais carentes de subsídios clínicos e diagnósticos traz embaraços de ordem gerencial e sanitária ao sistema de saúde, pois comprometem a assistência farmacêutica regular e fomentam o uso irracional de medicamentos.

    Full Text Available O artigo reafirma a importância das racionalidades leigas produzidas em Saúde Mental como expressões válidas de saber, com especial atenção aos aspectos éticos relacionados aos usos sociais dos conhecimentos gerados. Defende-se a ideia de que devem servir à criação de estratégias inovadoras que respondam efetivamente às necessidades das pessoas e como contrapoderes às lógicas hegemônicas. O contexto da governação da Saúde Mental em Portugal e as características estruturais da sociedade portuguesa refletem-se nos serviços efetivamente implementados e na percepção dos usuários a respeito da sua condição. A valorização das racionalidades leigas em um cenário hegemonicamente tecnicista e biomédico possibilita reafirmar a diversidade como condição humana. Nessa direção, insere-se como fundamento para a abordagem em realidades complexas e plurais como a Saúde Mental, incorporando a dimensão cultural às ações desenvolvidas.

    Full Text Available Com vistas a uma análise crítica das proposições de uma pedagogia dita empreendedora, o presente artigo tenciona trazer à baila o papel da racionalidade pedagógica moderna na constituição de determinadas formas de governo de si e dos outros, segundo as quais o indivíduo converte-se em capital de si mesmo, e sua própria vida, em ocasião de investimentos formativos ininterruptos. Elegendo Michel Foucault como interlocutor teórico principal, o estudo investiga algumas modulações do poder pastoral e da governamentalidade operadas em textoschave de Pestalozzi, Froebel, Herbart e, em especial, em Os anos de aprendizado, de Wilhelm Meister, romance de formação de Goethe. As reflexões assinalam o fato de que a modernidade pedagógica, em confluência aos preceitos do pietismo, forja um nexo indissociável entre querer, obedecer e empreender, convertendo-se em matriz de certos modos de veridicção/subjetivação correntes

Verificou-se a existência de concepção hegemônica acerca do fenômeno da dependência de drogas e do modo de intervenção no fenômeno, síntese de racionalidades diversas e, algumas vezes, contraditórias entre si. Tal concepção centra seu modelo na noção de doença, na meta da abstinência, no busca do controle sobre a adição, operando dispositivos médico-terapêuticos e morais. Nas raízes desta concepção, encontra-se uma perspectiva subjetivista, moralista e psicopatologizante, constituindo-se em visão ahistórica e pouco crítica da produção social em torno do uso de drogas, pautada numa racionalidade de predomínio metafísico, ainda que mesclado com outras racionalidades como a científica. Discute-se a importância de correlacionar o "horizonte de racionalidade" dos serviços de saúde com a problemática da eficácia e eficiência dos tratamentos na área da dependência de drogas.This article refers to the research discussion based on methodology of content analysis, which aims at making explicit the horizon of rationality of the services provided for alcohol users and other drugs in the Great Florianópolis region, to contribute to the establishment of qualitative parameters in the evaluation of health services.

    2012-03-01

    Full Text Available Este artigo discute o trabalho com a ética na escola (ensinos fundamental e médio a partir de uma crítica ao modelo de racionalidade demonstrativa, predominante desde o advento da modernidade. Como alternativa, apresenta outro modelo, a racionalidade argumentativa, discutida com base nas abordagens feitas por Chaïm Perelman, Lucie Olbrechts-Tyteca e Michel Meyer. Os dois primeiros autores formularam uma teoria da argumentação cujo objetivo é subsidiar os raciocínios próprios das ciências humanas e sociais, áreas do conhecimento nas quais procedimentos típicos da racionalidade demonstrativa, como a dedução e o cálculo, não se aplicam. Já Meyer salienta a natureza problematizadora da racionalidade argumentativa, situando a retórica como meio de negociar as distâncias existentes entre os indivíduos a propósito de determinadas questões. Esse quadro teórico é complementado pela filosofia do pluralismo, apontada por Perelman como contraponto às visões de mundo alicerçadas sobre concepções unitárias da verdade, denominadas monismos. Nos marcos desses referenciais, a concepção ética universalista de Immanuel Kant e o relativismo proposto pela ética da estética defendida por Michel Maffesoli são discutidos. Em um segundo tópico, a ética na educação escolar é problematizada tendo em vista a seguinte questão: como formar o caráter do aluno sem recair em algum tipo de doutrinação? Na medida em que ética e moral dizem respeito a essa questão, discutimos como os dois termos vêm sendo compreendidos e propomos tomá-los como instâncias intercambiáveis. As conclusões que apresentamos com base nessas discussões não objetivam solucionar os problemas inerentes aos hábitos e às atitudes dos discentes, mas colocam-se como contribuições para a reflexão dos docentes acerca de suas práticas pedagógicas.This article discusses the work on ethics in school (primary and secondary education with basis on a critique

    1984-01-01

    The Numerical Aerodynamic Simulation (NAS) Program is designed to provide a leading-edge computational capability to the aerospace community. It was recognized early in the program that, in addition to more advanced computers, the entire computational process ranging from problem formulation to publication of results needed to be improved to realize the full impact of computational aerodynamics. Therefore, the NAS Program has been structured to focus on the development of a complete system that can be upgraded periodically with minimum impact on the user and on the inventory of applications software. The implementation phase of the program is now under way. It is based upon nearly 8 yr of study and should culminate in an initial operational capability before 1986. The objective of this paper is fivefold: 1) to discuss the factors motivating the NAS program, 2) to provide a history of the activity, 3) to describe each of the elements of the processing-system network, 4) to outline the proposed allocation of time to users of the facility, and 5) to describe some of the candidate problems being considered for the first benchmark codes

    Full Text Available A ciência é uma forma de conhecimento que foi instituída como a forma de conhecer a verdade única e universalmente válida, assente nas questões epistemológicas e nos critérios de rigor metodológico. O saber leigo, popular, que preenche a vida e orienta a ação quotidiana, busca o significado através do simbólico cultural, no que é o oposto do conhecimento científico. A questão das possibilidades de conhecimento sobre a realidade social situou o debate nos modos de produção de conhecimento e na consequente contingência dessas mesmas produções, o que sustenta a afirmação de que todas as formas de conhecimentos são válidas nos seus contextos de produção. Em matéria de saúde e doença, a produção sociológica tem desvendado os conteúdos do saber leigo e a sua incontestável presença na experiência individual, desde a percepção dos fenômenos no corpo até a relação com a instituição médica. Este texto parte de uma reflexão sociológica sobre a questão do conhecimento. Em seguida, revê o essencial da literatura sociológica sobre o saber leigo de saúde e doença. Finaliza com uma proposta de compreensão dos processos do saber leigo como racionalidades que, na forma de configurações de elementos interdependentes, sustentam as práticas de saúde na vida quotidiana.Science is the form of knowledge that has been established as a way to know the only and universally valid truth, based on the epistemological questions and criteria of methodological rigor. The lay knowledge that fills life and guides daily actions, seeks meaning through the symbolic cultural, as opposed to scientific knowledge. The issue of knowledge possibilities about the social reality placed the debate on ways of knowledge production and the consequent contingency of those productions, which substantiates the claim that all forms of knowledge are valid in their context of production.

Tal relação só pode ser desvendada numa modernidade que se apresenta hegemonizada por um "racionalismo de domínio do mundo". Procurarei evidenciá-la relacionando o caráter trágico da cultura ao método racionalista, às racionalizações modernas e à responsabilidade ética.The text argues that there is a close relationship between rationality and tragedy in Weberian thought. Such a relationship can only be understood in the context of modernity which is ruled by a "world domination rationalism". I will try to make this relationship evident by relating the tragic character of culture to the rationalistic method, to modern rationalizations and, finally, to ethical responsibility.

    Full Text Available Resumo Este artigo se propõe a discutir a ideia de racionalidade que está no coração das abordagens deliberacionistas de democracia. Essa discussão embasa a realização de um estudo empírico focado em um banco de dados com 2.375 comentários sobre direitos LGBT em quatro arenas online: Youtube, Facebook, comentários de notícias e Votenaweb. O objetivo é discutir os principais fatores a influenciar no incremento do provimento de razões por postagens nessas arenas. Na análise, testamos cinco hipóteses: (H1 A chance de postagens apresentarem justificativas depende da plataforma em que se encontram essas postagens; (H2 A chance de postagens apresentarem justificativas é maior em debates em que há equilíbrio entre as posições defendidas; (H3 A chance de postagens apresentarem justificativas tende a ser maior quando há mais reciprocidade; (H4 A chance de postagens apresentarem justificativas é menor se o nível de desrespeito é maior; e (H5 A chance de postagens apresentarem justificativas é menor em mensagens enviadas por anônimos. Os resultados indicam que, entre as variáveis testadas, a "plataforma" e a "presença de respeito" são as mais importantes para induzir o provimento de justificativas.

Para ello, procuraremos describir un procedimiento discursivo singular en el relato mediático a raíz de los resultados de nuestro trabajo de campo: la víctima de un delito, en caso de tener antecedentes penales, será configurado como victimario. Operación discursiva que cristaliza una de las tantas manifestaciones de una racionalidad mediática-penal neoliberal donde por una parte, se condena justificando la muerte de la víctima por pertenecer a un sector social que no merece vivir y por otro, construye la figura de una víctima que pronto será victimario de si-mismo. [en] In this paper we propose, as a general objective, inquiring about media constructions around the figure of the “dangerous individual” in the discoruse of local press media, taking the case of the newspaper La Capital of Rosario. For that, we will describe a singular process: if a victim of crime have criminal records, will be configured as a victimizer. Discursive operation that cristalice one of the many manifestations of a neo-liberal-penal-media rationality where on the one hand, condemn justifying the death of the victim for belong to a social sector that does not deserve to live and on the other, builds the victim figure that will be soon a victimizer of himself.

    Full Text Available A partir dos processos de reforma gerencial colocados em prática em âmbito mundial, desencadearam-se propostas de reformas seguindo esta mesma lógica, também em nível estadual. O programa Choque de Gestão, implementado no Estado de Minas Gerais, é um exemplo deste tipo de proposta e merece destaque por ser avaliado de maneira bastante positiva na literatura especializada. Neste sentido, o objetivo do presente trabalho é analisar em que medida o programa Choque de Gestão, do Governo do Estado de Minas Gerais, compreende as diferentes dimensões de desempenho. Para tal, propõe-se um modelo teórico que relacione os conceitos de racionalidade instrumental e racionalidade substantiva, conforme analisadas por Ramos (1989, com o paradigma multidimensional proposto por Sander (1995. Para este último, a noção de desempenho deve ser pensada de forma mais ampla, tendo como base os critérios de eficiência, eficácia, efetividade e relevância. Aos conceitos de eficiência e eficácia relaciona-se o de racionalidade instrumental, baseada no cálculo utilitário das conseqüências, e aos de efetividade e relevância, o de racionalidade substantiva, fundamentada em valores. A relação entre os conceitos representa o quadro referencial de análise da pesquisa. Optou-se pela pesquisa qualitativa e os dados foram coletados por meio de pesquisa documental e analisados por meio do método de análise argumentativa. Para a realização da análise, foram utilizadas as categorias de substantividade e instrumentalidade, e foram criados indicadores, com base no referencial teórico, de acordo com as categorias trabalhadas. Por meio destes indicadores, analisou-se o documento Plano Mineiro de Desenvolvimento Integrado (PMDI, que consiste no planejamento de longo prazo do programa Choque de Gestão. A partir da análise realizada, pode-se observar que o conceito de desenvolvimento orientador do PMDI está impregnado de elementos substantivos, como a

Para tanto tentamos definir um possível conceito de ativismo judicial e as suas origens na tradição jurídica estadunidense. Nesse primeiro momento utilizamos o método histórico analítico para contextualizar historicamente as categorias conceituais em estudo e o momento de surgimento do fenômeno nos Estados Unidos. Em seguida, passamos a estudar, com base no método crítico-comparativo, os elementos fundamentais que caracterizam a racionalidade política e a racionalidade jurídica. Ao final, discutimos as perspectivas para um juiz ativista no Brasil, especialmente quando atue na proteção dos direitos fundamentais e na garantia da supremacia da Constituição. Em termos gerais, nossas conclusões apontam critérios que permitam a definição do que seria um ativismo judicial positivo, em detrimento da sua espécie nociva à saúde da ordem constitucional.This article has as general goal to find parameters in order to determine when the judicial activism leaves the field of legal argumentation and becomes an instrument of political decision.

    Full Text Available Resumo O presente artigo teve por objetivo analisar a racionalidade política que rege o sistema prisional brasileiro na atualidade. Para isso, tomou-se como objeto de pesquisa os relatórios de inspeções realizadas em estabelecimentos penais brasileiros pelo Conselho Nacional de Política Criminal e Penitenciária (CNPCP nos anos de 2011 e 2012. A análise da superlotação da população encarcerada possibilitou inferir a lógica não somente limitada às prisões, mas expandida por todo o corpo social, direcionada principalmente àqueles à margem da produção e do consumo e, por isso, a prisão tal como se observou, funciona como efeito que conserva a função de reprodução desta racionalidade.

    Full Text Available A responsabilidade social das organizações compreende ações concretas expostas publicamente para anunciar uma nova postura dos dirigentes dos sistemas de produção frente às contradições e às tensões provocadas pelo capitalismo na sociedade. A partir dos conhecimentos da psicossociologia, nosso objetivo é refletir sobre a emergência desse tema para além do discurso positivista tradicional. Primeiramente analisaremos o assunto como parte da "nova ordem social" afirmada com a globalização. Nesse sentido, consideraremos a importância de observá-la em sua complexidade, compreendida, simultaneamente, enquanto ordem e desordem, racionalidade e subjetividade do sistema capitalista que a criou. Posteriormente, destacaremos a responsabilidade social nas organizações, reveladora da sua preocupação com a sustentabilidade social, mas também como meio de remissão da culpa pela destruição que o sistema produtivo impõe à imensa maioria da humanidade.

    2008-06-01

    Full Text Available Este artigo faz uma revisão das pesquisas acadêmicas sobre o Hip Hop, apontando a preponderância do conceito de identidade nas referidas teorizações. Neste sentido, pretende-se contextualizar a ascensão do conceito de identidade nas visões sobre o Hip Hop, em direção a sua conjugação com o conceito de cidadania. Tal lógica identitária está intimamente ligada à construção da noção de categorias desviantes. Forjada sob o pano de fundo da urbanização, a lógica identitária é a expressão acadêmica de uma racionalidade a que denominamos de paradigma preventivo, cuja função é antecipar-se a uma eventual potência violenta que os jovens moradores de periferia representariam. Portanto, trata-se de entender a fabricação do subúrbio e da juventude como problema social, analisando, assim, as concepções que dão sustentação aos ideais corretivos e moralizantes que as abordagens sobre o Hip Hop expressam através de uma ênfase nos seus benefícios identitários.

Procura mostrar a necessidade em que o filósofo se vê de superar a separação entre o domínio da "sensibilidade" e do "entendimento", como condição para redefinir o problema da racionalidade. Procura mostrar ainda que a "reflexão radical" proposta por Merleau-Ponty, em oposição à reflexão idealista, leva-o a retomar as tarefas que outrora cabiam à metafísica clássica.This paper investigates Merleau-Ponty's criticism of modern idealism, which stems from the reflective model adopted by the latter. It aims at showing the need the philosopher has of going beyond the separation between the realm of "sensitivity" and the one of "understanding", as a condition to redefine the problem of rationality. It aims also at showing that the "radical reflection" proposed by Merleau-Ponty, as opposed to idealistic reflection, leads him to resume the tasks that used to be dealt with by classical metaphysics.

    Full Text Available : Las encuestas llevadas a cabo durante el régimen militar pusieron de manifiesto que las evaluaciones de diferentes políticas públicas correlacionan muy poco entre sí, son particularmente bajas entre analfabetos y encuestados con niveles educativos bajos, y no constituyen buenos predictores de la intención de voto y de las preferencias partidistas. Sin embargo, datos procedentes de una amplia encuesta domiciliar preelectoral en el Distrito Federal, con una muestra aleatoria estratificada, contradicen estos resultados; existe correlación entre evaluaciones de distintas políticas públicas, la magnitud de las correlaciones entre evaluaciones de políticas públicas no sigue un patrón de relación con los niveles educativos y constituyen una excelente predictor de las preferencias de voto para las elecciones a gobernador. Las disparidades que arrojan estos resultados pudieran ser resultado de cambios reales en la población a lo largo de los últimos quince años, a especificidades del Distrito Federal (niveles de renta per cápita más altos y uno de los más altos niveles educativos del país, a una elección en la que el candidato de la gobernación saliente compite contra un exgobernador, al énfasis de la campaña del gobernador saliente, a características del régimen militar o a una combinación de todas ellas. Cualquiera que sea la explicación, las elecciones de 1998 mostraron la existencia de una racionalidad que conecta la intención de voto con la evaluación de políticas públicas. No obstante, este vínculo pudiera ser específico y no generalizable a otros niveles electorales ni a preferencias partidistas.

This article aims to examine training and employment programmes for the young (more specifically, the Spanish Social Guarantee Schemes—Programas de Garantía Social in relation to neoliberal political rationalities. We believe the introduction of neoliberal policies to have been greater and faster precisely in the periphery of the educational system. To that end, we intend to make teachers' participation in the operation of the policies conceptually visible. The professionals’ discourse about the socio-labour integration of the young –a discourse that legitimises their daily work – will be analysed on the basis of qualitative materials from in-depth interviews. This analysis allows us to: 1 show the new ways of defining and valuing the teaching activity required and generated by these practical and institutional changes; 2 the analysis evidences some of the effects of the emerging discourses as well as the strategic roles they play in connection with neoliberal governance styles.

    In this study, new and feasible UV-visible spectrophotometric and multivariate spectrophotometric methods were described for the simultaneous determination of hydrochlorothiazide (HCTZ), hydralazine hydrochloride (H.HCl), and reserpine (RES) in combined pharmaceutical tablets. Methanol was used as a solvent for analysis and the whole UV region was scanned from 200-400 nm. The resolution was obtained by using multivariate methods such as the net analyte signal method (NAS), principal component analysis (PCA), and net analyte signal-principal component analysis (NAS-PCA) applied to the UV spectra of the mixture. The results obtained from all of the three methods were compared. NAS-PCA showed a lot of resolved data as compared to NAS and PCA. Thus, the NAS-PCA technique is a combination of NAS and PCA methods which is advantageous to obtain the information from overlapping results.

  2. Racionalidad del terror

    Sauquillo, Julián

    2012-06-01

    Full Text Available Contemporary terrorism is not an ancestral, irrational, oriental, phenomenon. Nor is it a fanatical reaction of the religions that vindicate a backward society as against the developed societies of the first world. The terrorism of today is a thoroughly modern phenomenon: one of the worst monstrosities of modern society, supplied with rational planning of objectives. A captious interpretation of the Islamic religion endows terrorism with a universal projection among the multitudinous audience of the discontented with the might of that diffuse power that we know as the developed Western world. Al Qaeda does not hesitate to present its war against the West as «a war without quarter» lasting until the infidel Christians are eliminated and the world is subjugated to Islam In the meantime, in a similar conflictive sense, the theoretical campaign of Samuel Huntington across the entire planet responds with a paradigmatic post-cold war, capable of inflaming the international conflict, in a sense no less belligerent with the Anti-Occident than that employed by the radical Imams. As has been pointed out by Amartya Sen, to give priority in this way to the religious identity, the response of the West to international terrorism in calling it «islamic terrorism» is very clumsy, as it magnifies the importance of the religious authorities in detriment to governmental ways and means in the solving of problems.

    El terrorismo contemporáneo no es un fenómeno ancestral, irracional y oriental. Tampoco es una reacción fanática de las religiones que reivindican una sociedad atrasada frente a las sociedades desarrolladas del primer mundo. El terrorismo actual es un fenómeno plenamente moderno: uno de los peores engendros de la sociedad moderna, dotado de una planificación racional de objetivos. Una interpretación capciosa de la religión islámica dota al terrorismo de una proyección universal entre la numerosa audiencia de descontentos con el poderío de esa potencia difusa que conocemos como el Occidente desarrollado. Al Qaeda no duda en presentar su guerra con Occidente como una «guerra sin cuartel» hasta eliminar a los cristianos infieles y someter al mundo al Islam. Mientras tanto, en similar sentido conflictual, la campaña teórica de Samuel Huntington por todo el planeta, responde con un paradigma postguerra fría capaz de inflamar el conflicto internacional en un sentido no menos beligerante con anti-Occidente que el empleado por los imanes radicales. Como ha señalado Amartya Sen, al priorizar de esta forma la identidad religiosa, la respuesta de Occidente al terrorismo internacional como «terrorismo islámico» es muy torpe pues se magnifica la importancia de las autoridades religiosas en detrimento de los cauces gubernativos en la resolución de los problemas.

Canclini (1991; 1995, o consumo serve para "pensar". A articulação entre seis racionalidades - cultural, dos desejos, dos aspectos simbólicos e estéticos, de interação sociopolítica, de integração social (CANCLINI, 1991 – seria um modo de refletir sobre as condições de consumo e cidadania. Nos anos 1990, o autor propunha pensar sobre o consumo como a construção de um subcampo de estudos. O texto aborda teorias da Antropologia do consumo para entender a produção de sentido.

MÉTODOS: Estudo descritivo retrospectivo com base em 27 ações julgadas em 2ª instância no Estado do Rio de Janeiro em 2006. Os processos originais foram solicitados ao Arquivo Central do Tribunal de Justiça do Estado do Rio de Janeiro, fotografados e analisados na íntegra. RESULTADOS: Todas as ações incluíram prescrição e atestado médicos. As prescrições estavam em desacordo com a legislação. Não houve perícia médica em nenhuma das ações e em 7,4% constavam exames complementares. Apesar da escassa informação médica contida nos autos, todos os pedidos foram deferidos. CONCLUSÕES: O acolhimento de demandas judiciais carentes de subsídios clínicos e diagnósticos traz embaraços de ordem gerencial e sanitária ao sistema de saúde, pois comprometem a assistência farmacêutica regular e fomentam o uso irracional de medicamentos.OBJETIVO: Caracterizar los principales elementos procesales, medico-científicos y sanitarios que respaldan las decisiones de las demandas judiciales individuales por medicamentos consideradas esenciales.

METHODS: Retrospective descriptive study based on 27 cases ruled on by the Court of Appeals in Rio de Janeiro, Southeastern Brazil, in 2006. The original proceedings were solicited from the Central Archive of the Court of Justice of the State of Rio de Janeiro and were photographed and analyzed in full. RESULTS: Prescriptions and medical certificates were present in 100% of the lawsuits. All prescriptions lacked conformity to legislation. No expert medical reports were added, and only 7.4% of the lawsuits presented complementary examinations. In spite of the scarcity of medical information present in the records, all of the demands were granted. CONCLUSIONS: The admission of judicial demands devoid of clinical and diagnostic substantiation results in managerial and health-related constraints on the health system. Besides creating havoc in standard pharmaceutical services, badly justified medicine demands may compromise rational drug use.

    Full Text Available En el campo de la salud las revisiones sistemáticas y el metaanálisis (MA han cobrado auge, ya que permiten congregar estudios de características similares y generar indicadores que describan el riesgo o el beneficio de intervenciones clínicas asociadas a la presencia de un problema de salud. Para interpretar el MA y darle su justa dimensión, es necesario tomar en cuenta la racionalidad del marco teórico que lo sustenta, sus criterios metodológicos y la posible relación causal entre exposición y evento, además del contextualizar la información. Actualmente, un gran reto constituye el análisis y la síntesis de la mayor cantidad de información para tomar decisiones de manera rápida y asertiva Este artículo hace un breve recorrido por la racionalidad científica y su aplicación en la teoría causal en el marco de la epidemiología, para sentar los cimientos que permitan evaluar la pertinencia y validez de las decisiones que se tomen con base en estos análisis.Currently, the challenge is to analyze and synthesize as much information as possible in order to make quick, correct decisions. Systematic reviews and meta-analysis have quickly arisen in the health field because they allow researchers to congregate studies of similar characteristics to generate estimators that describe the risk or benefit of practices related to health problems. To understand and attach the appropriate importance to meta-analyses, it is necessary to consider the rationale of the theoretical framework, the methodological criteria, and the possible causal relationship between exposure and outcome, besides contextualizing the information. This paper briefly explores scientific rationality and its application in causal theory within an epidemiological framework, to set the basis that allows decision-makers and health professionals to evaluate the appropriateness and validity of conclusions derived from this type of analyses.

Ante la persistencia de una cuestión social, ahora a nivel global, que se vuelve cada vez más una cuestión antropológica, se requiere ampliar el concepto de racionalidad económica. The pope Benedict XVI propose in Caritas in veritate to broaden the concept of reason. In view of the seriousness of the social question, especially at global level, that became an anthropolical question, it needs to broaden the concept of economic rationality. It is posible a dialogue between economics, ethics and theology? This paper explore some anthropological suppositions of economy theory by N. G. Mankiw, the concept of homo economicus, his economic's rationality. R. González F. critizes from ethics the homo economicus moral. In view of a complex scarcity, its means scarcity of economics goods and scarcity of moral goods, the person needs a complex rationality. The ethics is essential in the economics decisions. The Holy Father in Caritas in veritate wants to illuminate the economy with the theological anthropology and with a personalist ethics. He propose to broaden the concept of economic rationality, he point out a logic of gratuitousness that complement with a logic of market. Thus the complex of this rationalities in the economy makes necessary to do a interdisciplinary dialogue at human service. The University is the place to do this dialogue.

    During the early decades of the twentieth century, urban elites in Mexico City pursued ideals of modernity and hygiene following a rationale inspired on positivist values which later served as the foundations for establishing urban planning practice as an instrument of power. Even when the transfer of urban models was an extended practice throughout Latin America, the transformation of the capital city resulted not only from the application of those models, but from the actual generation of innovations and new urban technologies. Although it was argued that the displacement of poor inhabitants from high value potential real estate areas was part of the “civilizing process”, the construction and reconstruction of residential districts, parks and large infrastructure works finally exacerbated urban segregation and social polarization.

  5. Instrumentation development

    International Nuclear Information System (INIS)

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

    1988-01-01

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

    Full Text Available The objective of this article is to explore some aspects related to the origin of modern education rationality. The study is based on the analysis of different dimensions of the dialectical interaction historically established between the rational logic behind the structural changes of the capitalist society and the construction of the modern liberal education perspective. With the purpose of defining the keys to the process, the first section provides a brief reference to the foundations of the origin of rational thinking and those of modernity, which was caused by the secularization process suffered by the universe of the renaissance culture. In the second part we discuss some dimensions of illustrations and the encyclopedia as basic cultural and education projects in the rational organization of society in the XVIII century. The third section explores some dimensions of the connection between capitalist modernization and educational rationality through some of the main historical factors: the creation of State-nations, nationality and citizenship, the rationality of liberal capitalism, the universality and ethnocentrism of the elite culture, the instrumental reason and the view of progress as technical evolution. In addition, we highlight the State’s adoption of education as part of the construction of the public sphere by emphasizing the rational and legitimating role that lies at the basis of these historical processes. Finally, the fourth section analyzes how the creation of modern rationality takes on a historical view of social progress neglecting humanistic ethics. This process influences the emergence of an educational rationality based on the ideological justification of inequality and on a meritocratic view of the rational society, as Tourine has defined it (1993.

    At this year's particle physics conference at Brighton, a parallel session was given over to instrumentation and detector development. While this work is vital to the health of research and its continued progress, its share of prime international conference time is limited. Instrumentation can be innovative three times — first when a new idea is outlined, secondly when it is shown to be feasible, and finally when it becomes productive in a real experiment, amassing useful data rather than operational experience. Hyams' examples showed that it can take a long time for a new idea to filter through these successive stages, if it ever makes it at all

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

    Full Text Available O processo da área da construção civil é bastante heterogêneo, contemplando diferentes âmbitos de organização produtiva e de formas de comercialização de seus produtos finais, as construções. Nas construções, a complexidade e a indispensabilidade de planejamento e gerenciamento são agravadas pela crescente busca do mercado por maior qualidade em seu desenvolvimento e melhor desempenho do produto final. Isso pode não direcionar a comunicação entre os agentes envolvidos e racionalizar a construção e a edificação, mas também mostrar alternativas inteligentes e sustentáveis que respondam à necessidade de minimização dos impactos ambientais. A discussão que envolve os conceitos de construções inteligentes e sustentáveis, apesar de ser vista no meio acadêmico, parece ainda não encerrada e engloba os diferentes níveis de organização do indivíduo e dasociedade. O presente estudo tem como objetivo discutir o uso desses conceitos no processo construtivo e em seu resultado final, com a finalidade de identificar possíveis relações entre os mesmos e as suas contribuições no contexto da sustentabilidade da construção civil. Observou-se que as inovações tecnológicas dispostas nas várias etapas do processo (construção até o produto final, geraram soluções sustentáveis que deixam sua contribuição para amenizar os impactos no meio ambiente. O trabalho contribui para uma reflexão sobre conceitos de sustentabilidade dentro de uma visão mais integral para a arquitetura, abordando o processo e o produto da produção da arquitetura.

Uma delas, minoritária, baseia-se na prerrogativa do Estado na gestão do dia a dia prisional. A outra é relativa à negociação da pacificação do presídio entre o Estado e as lideranças dos presos. Embora, no primeiro caso, a prerrogativa do Estado possa ser vinculada às condições institucionais adequadas e, no segundo (negociação entre o estado e as lideranças dos presos às condições precárias dos presídios, como superlotação, número reduzido de agentes penitenciários, entre outros, a análise apontou que ambas as modalidades traduzem formas de relacionamentos e interações sociais historicamente produzidas entre o Estado e a sociedade, que remetem à fundação da República, recriadas através do habitus dos atores sociais, não se restringindo exclusivamente ao espaço social das prisões.

    1976-09-01

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

Sin embargo, datos procedentes de una amplia encuesta domiciliar preelectoral en el Distrito Federal, con una muestra aleatoria estratificada, contradicen estos resultados; existe correlación entre evaluaciones de distintas políticas públicas, la magnitud de las correlaciones entre evaluaciones de políticas públicas no sigue un patrón de relación con los niveles educativos y constituyen una excelente predictor de las preferencias de voto para las elecciones a gobernador. Las disparidades que arrojan estos resultados pudieran ser resultado de cambios reales en la población a lo largo de los últimos quince años, a especificidades del Distrito Federal (niveles de renta per cápita más altos y uno de los más altos niveles educativos del país, a una elección en la que el candidato de la gobernación saliente compite contra un exgobernador, al énfasis de la campaña del gobernador saliente, a características del régimen militar o a una combinación de todas ellas. Cualquiera que sea la explicación, las elecciones de 1998 mostraron la existencia de una racionalidad que conecta la intención de voto con la evaluación de políticas públicas.

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

    The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration in the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability (SSI), Human Systems Integration (HSI), and Communications (Comm), and Certification to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Detect and Avoid (DAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project is conducting a series of human-in-the-loop (HITL) and flight test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity, and

And it is from this instrument that many other tests are obtained later in the course of criminal investigations or criminal proceedings. It must be, therefore, that research objective finds alternatives to limit and adapt the instrument to the Federal Constitution, which can be done from a rationality of principles. A rationality of principles that takes into account the historical and theoretical tradition of Premial right recognized everywhere, but its effects in the sphere of criminal proceedings. Effects that can affect a number of other rights, such as the right to silence, to legal defense, proportionality, retribution, equality of arms. It must be, therefore, a new appreciation about this institute, so that it is used in exceptional situations, respecting always the ideas of voluntariness and subsidiarity, so that the Federal Constitution and the fundamental principles of criminal procedure are respected.

Este hecho supone que el puesto y la función de la mujer en la Iglesia quedaron afectados cuando se declaró a Santa Teresa Doctora de la Iglesia. Camino de Perfección es la primera obra impresa de Santa Teresa, en el año 1583 quiere ser un libro guía para las comunidades. Es un itinerario de conversión recorrido con una determinada "racionalidad apasionada" que desenmascara todo lo que no está al servicio del Reino. El presente estudio pretende ayudar a detectar la racionalidad teológica de Teresa desde la relación razón y amor en su obra Camino de perfección. En él se comienza a descubrir la propia sistematicidad del pensar de esta autora. Teresa ha ido vertiendo sus ideas respecto a la realidad de todo lo humano. Lo hace de un modo experiencial y sin atenerse, demasiado, a las normas de uso de los grandes conceptos en su épocaSt. Theresa of Avila is one of the great figures of the mysticism of the Spanish "Golden Age". Paul VI declared her a Doctor of the Church on September 27th, 1970. This fact presupposes that the place and function of women in the Church were influenced when St. Theresa was declared Doctor of the Church. Road of Perfection is the first printed work of St. Theresa's, in the year 1583, and was intended to be a guide for communities. It is an itinerary of conversion traveled through with a determined "passionate rationality" that unmasks everything not at the service of the Kingdom. The present study intends to help detect the theological rationality of Theresa from the reason-love relationship in her work Road of Perfection. In it the author's own systematic thought begins to be discovered, depositing her ideas in relation to the reality of all that is human. She does this in an experiential way and without overly depending upon the norms of the

    The Numerical Aerodynamic Simulation (NAS) Systems Division received an Intel Touchstone Sigma prototype model Paragon XP/S- 15 in February, 1993. The i860 XP microprocessor with an integrated floating point unit and operating in dual -instruction mode gives peak performance of 75 million floating point operations (NIFLOPS) per second for 64 bit floating point arithmetic. It is used in the Paragon XP/S-15 which has been installed at NAS, NASA Ames Research Center. The NAS Paragon has 208 nodes and its peak performance is 15.6 GFLOPS. Here, we will report on early experience using the Paragon XP/S- 15. We have tested its performance using both kernels and applications of interest to NAS. We have measured the performance of BLAS 1, 2 and 3 both assembly-coded and Fortran coded on NAS Paragon XP/S- 15. Furthermore, we have investigated the performance of a single node one-dimensional FFT, a distributed two-dimensional FFT and a distributed three-dimensional FFT Finally, we measured the performance of NAS Parallel Benchmarks (NPB) on the Paragon and compare it with the performance obtained on other highly parallel machines, such as CM-5, CRAY T3D, IBM SP I, etc. In particular, we investigated the following issues, which can strongly affect the performance of the Paragon: a. Impact of the operating system: Intel currently uses as a default an operating system OSF/1 AD from the Open Software Foundation. The paging of Open Software Foundation (OSF) server at 22 MB to make more memory available for the application degrades the performance. We found that when the limit of 26 NIB per node out of 32 MB available is reached, the application is paged out of main memory using virtual memory. When the application starts paging, the performance is considerably reduced. We found that dynamic memory allocation can help applications performance under certain circumstances. b. Impact of data cache on the i860/XP: We measured the performance of the BLAS both assembly coded and Fortran

La deficiencia congénita o adquirida de proteínas de la coagulación, como las proteínas C y S, se asocia con eventos trombóticos antes de los 30 o 40 años. La trombosis venosa profunda es considerada la manifestación clínica más frecuente, aunque también puede verse asociada con enfermedad cerebro vascular, pérdidas recurrentes de embarazos y otros estados isquémicos. En la actualidad, las enfermedades trombóticas constituyen una de las primeras causas de fallecimiento en el mundo; la morbimortalidad anual por trombosis, ya sea arterial o venosa, es de aproximadamente dos millones de personas. Presentamos un caso con antecedentes de pérdidas recurrentes de embarazos y trombosis venosa profunda en miembros inferiores con deficiencia combinada de proteínas C y S.

    Full Text Available O objetivo do presente artigo é analisar criticamente o discurso elaborado pela literatura de autoajuda financeira (LAF no contexto geral do processo de financeirização. Esta análise utiliza como material empírico publicações próprias deste género disponíveis no mercado editorial português, desenvolvendo‑se de acordo com a grelha teórica dos estudos sobre governamentalidade (governmentality studies de inspiração foucaultiana. Na primeira secção é revisto o conceito de financeirização, apontando para as suas debilidades e forças teóricas e empíricas. A falta de atenção aos aspetos microssociológicos é precisamente uma das debilidades que justifica a necessidade de explorar, numa segunda secção, o tipo de subjetividade relacionada com o capitalismo financeirizado. A terceira secção analisa as dimensões centrais dessa subjetividade tal como é apresentada pela LAF, o que inclui um enquadramento das características destas publicações assim como o estudo do motivo, do objetivo e da forma de fazer aquilo que a autoajuda aconselha. A última secção centra‑se na base social dos textos como ferramentas discursivas próprias de uma racionalidade política neoliberal.

    Sarma, Sreeramula Rajeswara

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

    Full Text Available Instrumental rationality built the concept of technology appropriated by the capitalist system. This has become a strategic factor for economic development and instrument of externalities control by artificial state of natural processes, creating serious social and ecological problems. However, through economic inaccessibility and due to severe environmental costs, it was necessary to build palliative mechanisms that promote the transition from the traditional technique to modern technology. In this context, the concept of alternative technologies arises and, differentiated by the emphasis on low cost and efficient use of locally abundant resources, is defined by social accessibility and ecological efficiency. This model, inspired by the environmental rationality with emphasis on supplying the needs of rural communities, has been the foundation of the actions of institutions that produce and diffuse these technologies focused on the development of family farming in Brazil. This paper presents the vision of family farmers about the difficulties encountered in the production process and the results obtained through the agency of one of these institutions, the Service of Alternative Technologies (SERTA, specifically, from the analysis of their activities in semi-arid region of Pernambuco (Brazil, in the unit located in Ibimirim-PE.

    We report the highest mobility values above 2000 cm 2 /Vs in Si doped GaNAs film grown by molecular beam epitaxy. To understand the feature of the origin which limits the electron mobility in GaNAs, temperature dependences of mobility were measured for high mobility GaNAs and referential low mobility GaInNAs. Temperature dependent mobility for high mobility GaNAs is similar to the GaAs case, while that for low mobility GaInNAs shows large decrease in lower temperature region. The electron mobility of high quality GaNAs can be explained by intrinsic limiting factor of random alloy scattering and extrinsic factor of ionized impurity scattering.

    Full Text Available This paper discusses the influence of spiritual values in the insertion of socio-environmental dimensions in management processes. A critical analysis of the socio-economic experience named Communion Economy is presented, which highlights the spiritual, ethical and moral values in this economy as inherent motivators of social and environmental considerations. It is a sui generis experience, born within the limits of a religious movement, the Movement of Focolares. It is currently active in 735 companies, mostly small ones, located in several countries, which operate in various economic activities and aggregate a dimension of solidarity to their formal market activity. The considerations presented here reveal a management form based not only on criteria of instrumental rationality (effectiveness, income and performance but also on dimensions of substantive rationality (ethical, aesthetic and moral.

    Full Text Available O presente artigo insere-se em projeto de pesquisa-intervenção sobre a música e suas articulações identitárias nas corporações musicais da região dos Campos das Vertentes, em especial São João del-Rei e cidades vizinhas. Nessa região, a música tem papel significativo na formação da identidade cultural dos cidadãos e na história dos municípios. O recorte atual apresenta uma investigação sobre determinações de gênero, visando conhecer como se dá a participação de musicistas nas bandas e orquestras da região. Para tanto, utilizou-se a análise arqueológica do discurso, a fim de contrapor falas de musicistas às falas de músicos das corporações e, também, às falas masculinas presentes na filosofia e ao discurso utópico sobre a mulher. Observou-se que as diferenças de gênero tradicionais conservam-se encobertas no cotidiano das corporações musicais. Entretanto, observou-se também que as musicistas começam a ser reconhecidas nas corporações e, sobretudo, reconhecem-se como capazes de, nelas, alçarem voos.

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

    A liquid metal cooled nuclear reactor is described which has an equal number of fuel sub-assemblies and sensing instruments. Each instrument senses temperature and rate of coolant flow of a coolant derived from a group of three sub-assemblies so that an abnormal value for one sub-assembly will be indicated on three instruments thereby providing for redundancy of up to two of the three instruments. The abnormal value may be a precurser to unstable boiling of coolant

    Consiglio, Maria C.; Chamberlain, James P.; Munoz, Cesar A.; Hoffler, Keith D.

    2012-01-01

    One of the major challenges facing the integration of Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is the lack of an onboard pilot that can comply with the legal requirement identified in the US Code of Federal Regulations (CFR) that pilots see and avoid other aircraft. UAS will be expected to demonstrate the means to perform the function of see and avoid while preserving the safety level of the airspace and the efficiency of the air traffic system. This paper introduces a Sense and Avoid (SAA) concept for integration of UAS into the NAS that is currently being developed by the National Aeronautics and Space Administration (NASA) and identifies areas that require additional experimental evaluation to further inform various elements of the concept. The concept design rests on interoperability principles that take into account both the Air Traffic Control (ATC) environment as well as existing systems such as the Traffic Alert and Collision Avoidance System (TCAS). Specifically, the concept addresses the determination of well clear values that are large enough to avoid issuance of TCAS corrective Resolution Advisories, undue concern by pilots of proximate aircraft and issuance of controller traffic alerts. The concept also addresses appropriate declaration times for projected losses of well clear conditions and maneuvers to regain well clear separation.

    Full Text Available El objetivo del artículo es mostrar que el problema central detrás del debate sostenido entre Daniel Kahneman y Gerd Gigerenzer acerca del papel del razonamiento heurístico en nuestra comprensión de la racionalidad humana es cómo caracterizar el razonamiento normativo. Para ello, muestro que en la literatura sobre razonamiento heurístico se ha asumido una distinción tajante –incluso en muchos casos se asume una oposición– entre razonamiento formal y razonamiento heurístico. Argumento que la discusión se ha centrado en cuál de estos tipos de razonamientos debe ser considerado como modelo de nuestro razonar; hago ver que analizando textos de George Pólya y de Herbert A. Simon podemos rastrear este problema. Este análisis nos permitirá hacer notar la relevancia de dicho debate, que muchas veces ha sido una mera disputa semántica. In this paper I argue that the central problem behind the debate between Daniel Kahneman and Gerd Gigerenzer regarding the role of heuristic reasoning in our comprehension of human rationality is the way in which we characterize normative reasoning. To this end, I show how, in the recent literature about heuristic reasoning, a sharp distinction has been drawn –in certain cases, even an opposition– between formal and heuristic reasoning. I argue that the discussion has focused on which one of these kinds of reasoning should be taken as the right model of our reasoning. I show that this point may be tracked by analyzing the texts of George Pólya and Herbert A. Simon. This analysis will allow us to notice the relevance of said debate, which has, often times, been considered a mere semantic dispute.

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

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

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

    International Nuclear Information System (INIS)

    Swinth, K.L.

    1993-03-01

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

The operational aspects of ROA flight, while similar, are not entirely identical to their manned counterparts and may not have been considered within the time-horizons of the automation tools. This analysis was performed to determine if flight characteristics of ROAs would be compatible with current and future NAS automation tools. Improvements to existing systems / processes are recommended that would give Air Traffic Controllers an indication that a particular aircraft is an ROA and modifications to IFR flight plan processing algorithms and / or designation of airspace where an ROA will be operating for long periods of time.

La entrada de rotavirus a las células parece estar mediado por interacciones secuenciales entre las proteínas estructurales virales y algunas moléculas de la superficie celular. Sin embargo, los mecanismos por los cuales el rotavirus infecta la célula diana aún no se comprenden bien. Existe alguna evidencia que muestra que las proteínas estructurales de rotavirus VP5* y VP8* interactúan con algunas moléculas de la superficie celular. La disponibilidad de las proteínas estructurales de rotavirus recombinantes en cantidad suficiente se ha convertido en un aspecto importante para la identificación de las interacciones específicas de los receptores virus-célula durante los eventos tempranos del proceso infeccioso. Objetivo. El propósito del presente trabajo es realizar un análisis de las interacciones entre las proteínas estructurales de rotavirus recombinante VP5*, VP8* y VP6, y las proteínas celulares Hsc70 y PDI utilizando sus versiones recombinantes purificadas. Materiales y métodos. Las proteínas recombinantes de rotavirus VP5* y VP8* y las proteínas recombinantes celulares Hsc70 y PDI se expresaron en E. coli BL21 (DE3, mientras que VP6 se expresó en células MA104 con virus vaccinia recombinante transfectada. La interacción entre el rotavirus y las proteínas celulares se estudió mediante ELISA, co-inmunoprecipitación y SDS-PAGE/ Western. Resultados. Las condiciones óptimas para la expresión de proteínas recombinantes se determinaron y se generaron anticuerpos contra ellas. Los resultados sugirieron que las proteínas virales rVP5* y rVP6 interactúan con Hsc70 y PDI in vitro. También se encontró que éstas proteínas virales recombinantes interactúan con Hsc70 en las balsas lipídicas (“Rafts” en un cultivo celular. El tratamiento de las células, ya sea con DLP o rVP6 produjo significativamente la inhibición de la infección por rotavirus. Conclusión. Los resultados permiten concluir que r

    Full Text Available As normas internacionais vigentes evidenciam a necessidade do julgamento e tomada de decisão dos profissionais da contabilidade nas questões que envolvem o reconhecimento e a mensuração dos fatos contábeis. O objetivo deste estudo é avaliar a capacidade de julgamento e tomada de decisão de acadêmicos de ciências contábeis na resolução de questões que envolvem as normas internacionais. Em função das características do estudo, buscou-se, no desenvolvimento da análise, a associação com as heurísticas clássicas da tomada de decisão: representatividade, disponibilidade, ancoragem e ajuste. A pesquisa caracteriza-se como um estudo exploratório, survey com abordagem quantitativa. A amostra consistiu de 97 alunos do curso de graduação em Ciências Contábeis de uma universidade de Santa Catarina. O questionário selecionou 6 questões que envolvem julgamento e tomada de decisão e integram provas do Conselho Federal de Contabilidade. Na análise das heurísticas, que envolvem o julgamento e a tomada de decisão, constatou-se maior uso das heurísticas da disponibilidade e ancoragem e ajuste nas questões analisadas. A média percentual de acertos nas seis questões foi considerada baixa, contudo, não invalida os resultados, mas chama a atenção para o grau de racionalidade limitada nas decisões. É preciso ressaltar que os vieses cognitivos podem ser provocados pelo uso das heurísticas. Os achados da pesquisa revelam pontos significativos e que reforçam a importância do julgamento e tomada de decisão na formação acadêmica, como habilidade do Contador. The current international standards emphasize the need for judgment and decision making of accounting professionals on issues involving the recognition and measurement of financial facts. The aim of this study is to evaluate the judgment and decision making of accountancy academic professionals in resolving issues involving international standards. Depending on the

    Full Text Available Nos anos recentes, as emoções chamaram a atenção das pesquisas sobre ação coletiva. A partir de uma concepção racional desta última, foi desenvolvida uma visão cognitiva da emoção- baseada em uma tradição ocidental que opõe racional a irracional, mente a corpo, privado a público- segundo a qual as emoções seriam fatores motivacionais. Neste artigo, elaboro uma revisão de parte de meu estudo etnográfico sobre fábricas recuperadas em Buenos Aires para analisar as emoções como práticas políticas. Proponho deslocar o debate sobre a irracionalidade/ racionalidade da ação e introduzir uma compreensão das práticas políticas como experiência encarnada. Com este objetivo, analiso a descrição que as/os trabalhadores/trabalhadores fizeram do momento da ocupação. Esta reconstrução demonstra a importância das emoções para articular a experiência e definir as reivindicações. O processo de construção de demandas implicou uma objetivação desta experiência e, ao mesmo tempo, de exposição pública de certas emoções e sentimentos.Emotions have achieved a certain prominence in recent studies of collective action. Based on a rationalist conception of the latter, many of the authors concerned have developed a cognitive view of emotion adhering to a western tradition of thought that divorces the rational from the irrational, mind from body and private from public. Emotions thereby become factors capable of explaining people's motivations in collective actions. In this article I review part of my ethnographic study of recovered factories in Buenos Aires in order to analyze emotions as political practices. I suggest shifting the debate away from irrational/rational action and towards an understanding of political practices as embodied experience. This aim in mind I analyze the workers' descriptions of the moment of occupation. This reconstruction shows us the importance of emotion in articulating the experience and in

    Full Text Available El artículo se enmarca en el debate en torno al concepto de riesgo que se da desde las ciencias sociales y humanas entre la denominada corriente realista –que tiende a asumir que las conductas que implican riesgo son irracionales y que aquellas que lo evitan son producto de la racionalidad– y la posición que, desde el constructivismo social, apunta a interpretar la toma de riesgo no como un hecho aislado e irracional sino como respuesta a lógicas complejas y particulares del contexto sociocultural en que se genera dicha decisión. Apoyando la última posición, este texto elabora parte de los resultados de un estudio doctoral en sociología, de corte etnográfico, entre jóvenes caleños y caleñas para (1 caracterizar las lógicas de racionalidad que sustentan ciertas prácticas en torno a la sexualidad, a la luz de factores como género y estrato socio-económico, y (2 analizar la concepción del riesgo más allá de su tradicional acepción negativa, para explorar las posibles funciones y valoraciones positivas asignadas por los sujetos en coherencia con su entorno socio-cultural. A partir de las nociones de análisis de género (en sus dimensiones de relacionalidad, historicidad y estructuras de poder y de estrato socio-económico (asumido como una categoría que supera los aspectos estrictamente económicos, se ha podido identificar que elementos como la valoración positiva del no uso del condón, las diferencias de género en la elección de la pareja sexual y los beneficios que representa tener un hijo o una hija a temprana edad, entre otros, juegan un papel fundamental en los procesos de negociación del riesgo. En este sentido, se argumenta que las conductas de riesgo están insertas en densos entramados de significación de fuerte vinculación a lo social y contextual.

    1999-01-01

    This paper presents and discusses the first Deep-Level transient spectroscopy (DLTS) data obtained from measurements carried out on both Schottky barriers and homojunction devices of GaInNAs. The effect of N and In doping on the electrical properties of the GaNInAs devices, which results in structural defects and interface states, has been investigated. Moreover, the location and densities of deep levels related to the presence of N, In, and N+In are identified and correlated with the device performance. The data confirmed that the presence of N alone creates a high density of shallow hole traps related to the N atom and structural defects in the device. Doping by In, if present alone, also creates low-density deep traps (related to the In atom and structural defects) and extremely deep interface states. On the other hand, the co-presence of In and N eliminates both the interface states and levels related to structural defects. However, the device still has a high density of the shallow and deep traps that are responsible for the photocurrent loss in the GaNInAs device, together with the possible short diffusion length. copyright 1999 American Institute of Physics

    1982-05-01

    The trend to develop a cheap electrochemical electric battery and the development of the Na/S system are discussed. The main element in this type of battery is the beta Al2O3 solid electrolyte. Characteristics for this material of first importance are: specific surface, density of green and of sintered material, absence of cracks, gas permeability, resistance to flexion, purity, electrical conductivity, crystal structure and dimensions. Influence of production method on all these characteristics were investigated, e.g., method of compacting powder, tunnel kiln sintering versus static chamber furnace sintering, sintering inside a container or not, and type of kiln material when sintering in a container. In the stationary chamber furnace, beta alumina ceramics were produced with a density of 3.2 g/cm3, a mechanical strength higher than 160 MPa, and an electrical conductivity of about 0.125 Ohm-1cm-1 at 300 C. The best kiln material proved to be MgO and MgAl2O3.MgO ceramics.

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

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

Según el artículo, el libre juego de las fuerzas del mercado no conduce a una distribución satisfactoria y si bien dicho mercado puede ser eficiente, es posible que no se caracterice por su equidad o justicia distributiva. Una alternativa planteada es la descentralización de las decisiones de los planificadores del estado hacia productores individuales y una mayor aproximación de la producción a la demanda,  con una intervención del estado en la creación de incentivos a la rentabilidad de las empresas. En últimas se plantea la combinación de mecanismos propios de economías socialistas con la economía capitalista que nos caracteriza.

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

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

    Introduction Neonatal abstinence syndrome (NAS) is withdrawal syndrome in newborns following birth and is primarily caused by maternal drug use during pregnancy. This study examines trends, population correlates, and policy implications of NAS in two Southwest border states. Materials and Methods A cross-sectional analysis of Hospital Inpatient Discharge Data (HIDD) was utilized to examine the incidence of NAS in the Southwest border states of Arizona (AZ) and New Mexico (NM). All inpatient hospital births in AZ and NM from January 1, 2008 through December 31, 2013 with ICD9-CM codes for NAS (779.5), cocaine (760.72), or narcotics (760.75) were extracted. Results During 2008-2013 there were 1472 NAS cases in AZ and 888 in NM. The overall NAS rate during this period was 2.83 per 1000 births (95% CI 2.68-2.97) in AZ and 5.31 (95% CI 4.96-5.66) in NM. NAS rates increased 157% in AZ and 174% in NM. NAS newborns were more likely to have low birth weight, have respiratory distress, more likely to have feeding difficulties, and more likely to be on state Medicaid insurance. AZ border region (border with Mexico) had NAS rates significantly higher than the state rate (4.06 per 1000 births [95% CI 3.68-4.44] vs. 2.83 [95% CI 2.68-2.97], respectively). In NM, the border region rate (2.09 per 1000 births [95% CI 1.48-2.69]) was significantly lower than the state rate (5.31 [95% CI 4.96-5.66]). Conclusions Despite a dramatic increase in the incidence of NAS in the U.S. and, in particular, the Southwest border states of AZ and NM, there is still scant research on the overall incidence of NAS, its assessment in the southwest border, and associated long-term outcomes. The Healthy Border (HB) 2020 binational initiative of the U.S.-Mexico Border Health Commission is an initiative that addresses several public health priorities that not only include chronic and degenerative diseases, infectious diseases, injury prevention, maternal and child health but also mental health and

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

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

    1988-01-01

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

    Full Text Available Os interesses transindividuais reclamam a adaptação das regras do tradicional processo civil, pensado e elaborado para tutelar o interesse particular. Neste artigo, será abordada a litispendência nas ações coletivas, suas características, efeitos e particularidades. Litispendência  é  a repetição de ação em curso. Em relação às ações coletivas, este fenômeno processual pode existir mesmo que a segunda ação seja proposta por  autor diverso. Isso porque, no pólo ativo da  demanda coletiva, a parte está em juízo defendendo interesse alheio, de grupo determinável ou indeterminável. Então, ainda que haja legitimadosdiversos no pólo ativo, buscando o mesmo interesse coletivo, na verdade, ambos os autores estão em juízo representando a mesma coletividade. É que,  no campo da legitimação extraordinária, ainda que a ação seja proposta por autor diferente, o titular do direito material estará igualmente representado,  havendo, portanto, repetição da causa em juízo. Com isso, pode-se afirmar haver litispendência dessas ações. Apesar de haver litispendência, o intuito do processo coletivo é a busca da verdade real e, por isso, seria prejudicial a extinção de uma das demandas. Portanto,  o que se quer provar é que o efeito típico da conexão pode ser aqui aplicado, ou seja, o efeito de reunião das ações para julgamento conjunto. Esta é a solução que mais atende ao resultado útil do processo na tutela coletiva.

    Full Text Available O estudo das fi nanças comportamentais vem ganhando destaque e sendo objeto de diversos trabalhos acadêmicos. Muitos conceitos tradicionais de economia, sobre o homem econômico, têm sido questionados, ao se considerarem aspectos observados na prática. Principalmente, a partir dos modernos estudos de economia comportamental, aponta-se que o homem se comporta de maneira enviesada e irracional, para tomar suas decisões. É infl uenciado por detalhes que podem levá-lo a fazer escolhas menos vantajosas, relacionadas ao seu dinheiro, e nem mesmo se dar conta disso. O efeito chamariz refere-se à infl uência que um item, a ser escolhido, exerce sobre aqueles que farão uma escolha, inclusive levando- os a tomar uma decisão que, anteriormente, era duvidosa, ou até mesmo a mudar uma escolha anterior. Esse efeito mostra como o homem cria falsas bases de comparação, para simplifi car um ambiente de escolha entre opções. O trabalho faz uma pesquisa sobre uma decisão de investimento, em que há duas situações, com a presença ou não de um chamariz, algo que pode infl uenciar a decisão fi nal dos investidores. Participaram da pesquisa 386 alunos de graduação do curso de Ciências Contábeis, de cinco universidades, do Distrito Federal. Os alunos foram considerados investidores capazes de analisar índices de liquidez e de julgar qual seria a melhor opção para investir. Viu-se que as pessoas se sentem incentivadas a investir em empresas nas quais foi criada uma falsa base de comparação, pela presença do chamariz. Esse efeito é observado com maior intensidade em alguns grupos específi cos de investidores. Sugere-se a elaboração de novas pesquisas na área, com o objetivo de observar esse efeito em outras situações e de divulgar o estudo das fi nanças comportamentais.

    We report a photoconductive switch using low temperature grown GaNAsSb as the active material. The GaNAsSb layer was grown at 200 °C by molecular beam epitaxy in conjunction with a radio frequency plasma-assisted nitrogen source and a valved antimony cracker source. The low temperature growth of the GaNAsSb layer increased the dark resistivity of the switch and shortened the carrier lifetime. The switch exhibited a dark resistivity of 10{sup 7} Ω cm, a photo-absorption of up to 2.1 μm, and a carrier lifetime of ∼1.3 ps. These results strongly support the suitability of low temperature grown GaNAsSb in the photoconductive switch application.

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

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

    2011-01-01

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

    In the past few years, GaInNAsSb has been found to be a potentially superior material to both GaInNAs and InGaAsP for communications wavelength laser applications. It has been observed that due to the surfactant role of antimony during epitaxy, higher quality material can be grown over the entire 1.2-1.6 μm range on GaAs substrates. In addition, it has been discovered that antimony in GaInNAsSb also works as a constituent that significantly modifies the valence band. These findings motivated a systematic study of GaInNAsSb alloys with widely varying compositions. Our recent progress in growth and materials development of GaInNAsSb alloys and our fabrication of 1.5-1.6 μm lasers are discussed in this paper. We review our recent studies of the conduction band offset in (Ga,In) (N,As,Sb)/GaAs quantum wells and discuss the growth challenges of GaInNAsSb alloys. Finally, we report record setting long wavelength edge emitting lasers and the first monolithic VCSELs operating at 1.5 μm based on GaInNAsSb QWs grown on GaAs. Successful development of GaInNAsSb alloys for lasers has led to a much broader range of potential applications for this material including: solar cells, electroabsorption modulators, saturable absorbers and far infrared optoelectronic devices and these are also briefly discussed in this paper.

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

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

    Recognizing that the University Reactor Instrumentation Program was developed in response to widespread needs in the academic community for modernization and improvement of research and training reactors at institutions such as the University of Florida, the items proposed to be supported by this grant over its two year period have been selected as those most likely to reduce foreed outages, to meet regulatory concerns that had been expressed in recent years by Nuclear Regulatory Commission inspectors or to correct other facility problems and limitations. Department of Energy Grant Number DE-FG07-90ER129969 was provided to the University of Florida Training Reactor(UFTR) facility through the US Department of Energy's University Reactor Instrumentation Program. The original proposal submitted in February, 1990 requested support for UFTR facility instrumentation and equipment upgrades for seven items in the amount of $107,530 with $13,800 of this amount to be the subject of cost sharing by the University of Florida and $93,730 requested as support from the Department of Energy. A breakdown of the items requested and total cost for the proposed UFTR facility instrumentation and equipment improvements is presented

    1994-12-31

    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.

    Energy Technology Data Exchange (ETDEWEB)

    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).

    Full Text Available The studies of Mehrabian and Russell (1974, (researchers in the field of environmental psychology, have been instrumental in spreading the idea that the environmental features at the point of sale cause emotional reactions that lead to behavior that is hard to explain from a cognitive standpoint. For this reason, merchandising implementation plays a key role, since its aim is to provide an appropriate store atmosphere and display products in a way that encourages buying activity. This paper investigates the effects of merchandising factors on retail sales.The study was carried out in two types of stores: experimental – where merchandising factors were employed, and control - where the design features of merchandising remained unchanged.The analysis of the results confirmed the income effect. . The increase in revenue can be an indicator that merchandising factors have an influence on the consumer´s store choice criteria and his/her behavior within a determined sales environment.

  8. Testing New Programming Paradigms with NAS Parallel Benchmarks

    2000-01-01

    Over the past decade, high performance computing has evolved rapidly, not only in hardware architectures but also with increasing complexity of real applications. Technologies have been developing to aim at scaling up to thousands of processors on both distributed and shared memory systems. Development of parallel programs on these computers is always a challenging task. Today, writing parallel programs with message passing (e.g. MPI) is the most popular way of achieving scalability and high performance. However, writing message passing programs is difficult and error prone. Recent years new effort has been made in defining new parallel programming paradigms. The best examples are: HPF (based on data parallelism) and OpenMP (based on shared memory parallelism). Both provide simple and clear extensions to sequential programs, thus greatly simplify the tedious tasks encountered in writing message passing programs. HPF is independent of memory hierarchy, however, due to the immaturity of compiler technology its performance is still questionable. Although use of parallel compiler directives is not new, OpenMP offers a portable solution in the shared-memory domain. Another important development involves the tremendous progress in the internet and its associated technology. Although still in its infancy, Java promisses portability in a heterogeneous environment and offers possibility to "compile once and run anywhere." In light of testing these new technologies, we implemented new parallel versions of the NAS Parallel Benchmarks (NPBs) with HPF and OpenMP directives, and extended the work with Java and Java-threads. The purpose of this study is to examine the effectiveness of alternative programming paradigms. NPBs consist of five kernels and three simulated applications that mimic the computation and data movement of large scale computational fluid dynamics (CFD) applications. We started with the serial version included in NPB2.3. Optimization of memory and cache usage

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

    Petrie, G.

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

    Neonatal abstinence syndrome (NAS) occurs in neonates whose mothers have taken addictive drugs or were under substitution therapy during pregnancy. Incidence numbers of NAS are on the rise globally, even in Austria NAS is not rare anymore. The aim of our survey was to reveal the status quo of dealing with NAS in Austria. A questionnaire was sent to 20 neonatology departments all over Austria, items included questions on scoring, therapy, breast-feeding and follow-up procedures. The response rate was 95%, of which 94.7% had written guidelines concerning NAS. The median number of children being treated per year for NAS was 4. Finnegan scoring system is used in 100% of the responding departments. Morphine is being used most often, in opiate abuse (100%) as well as in multiple substance abuse (44.4%). The most frequent forms of morphine preparation are morphine and diluted tincture of opium. Frequency as well as dosage of medication vary broadly. 61.1% of the departments supported breast-feeding, regulations concerned participation in a substitution programme and general contraindications (HIV, HCV, HBV). Our results revealed that there is a big west-east gradient in patients being treated per year. NAS is not a rare entity anymore in Austria (up to 50 cases per year in Vienna). Our survey showed that most neonatology departments in Austria treat their patients following written guidelines. Although all of them base these guidelines on international recommendations there is no national consensus. © Georg Thieme Verlag KG Stuttgart · New York.

    Armitage, D. Bruce

    1999-02-01

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

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

    A highly sensitive and compactly structured radiation measuring instrument for detecting ionizing radiation, in particular for measuring dose rates and contamination. The laminar structure of the associated counter tube, using only a few, simple plastic parts and a highly elastic counter wire, makes it possible to use the simplest manufacturing techniques. The service life of the counter tube construction, which is completely and permanently sealed and filled with gas, is expected to be more than 12 years. The described counter tube can be adapted in optimal fashion to the available space in a pocket instrument if it is used in combination with a specialized high-voltage generator which is low in interference voltage and with a pulse evaluation circuit having a means of compensating for interference voltage

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

    Cohen, David J.; Rossing, Thomas D.

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

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

    NASA currently is working with industry and the Federal Aviation Administration (FAA) to establish future requirements for Unmanned Aircraft Systems (UAS) flying in the National Airspace System (NAS). To work these issues NASA has established a multi-center "UAS Integration in the NAS" project. In order to establish Ground Control Station requirements for UAS, the perspective of each of the major players in NAS operations was desired. Three on-line surveys were administered that focused on Air Traffic Controllers (ATC), pilots of manned aircraft, and pilots of UAS. Follow-up telephone interviews were conducted with some survey respondents. The survey questions addressed UAS control, navigation, and communications from the perspective of small and large unmanned aircraft. Questions also addressed issues of UAS equipage, especially with regard to sense and avoid capabilities. From the civilian ATC and military ATC perspectives, of particular interest are how mixed operations (manned / UAS) have worked in the past and the role of aircraft equipage. Knowledge gained from this information is expected to assist the NASA UAS Integration in the NAS project in directing research foci thus assisting the FAA in the development of rules, regulations, and policies related to UAS in the NAS.

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

    Logan, Michael J.

    2012-01-01

    This paper discusses a proposed framework for the safe integration of small unmanned aerial systems (sUAS) into the National Airspace System (NAS). The paper briefly examines the potential uses of sUAS to build an understanding of the location and frequency of potential future flight operations based on the future applications of the sUAS systems. The paper then examines the types of systems that would be required to meet the application-level demand to determine "classes" of platforms and operations. A framework for categorization of the "intelligence" level of the UAS is postulated for purposes of NAS integration. Finally, constraints on the intelligent systems are postulated to ensure their ease of integration into the NAS.

    The effect of UV-activated hydrogenation on the performance of GaInNAs solar cells is presented. A proof-of-principle investigation was performed on non-optimum GaInNAs cells, which allowed a clearer investigation of the role of passivation on the intrinsic nitrogen-related defects in these materials. Upon optimized hydrogenation of GaInNAs, a significant reduction in the presence of defect and impurity based luminescence is observed as compared to that of unpassivated reference material. This improvement in the optical properties is directly transferred to an improved performance in solar cell operation, with a more than two-fold improvement in the external quantum efficiency and short circuit current density upon hydrogenation. Temperature dependent photovoltaic measurements indicate a strong contribution of carrier localization and detrapping processes, with non-radiative processes dominating in the reference materials, and evidence for additional strong radiative losses in the hydrogenated solar cells

    2012-07-01

    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.

    1989-01-01

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

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

    1998-01-01

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

    Full Text Available O artigo reflete sobre como a questão habitacional produzida historicamente no capitalismo caracteriza-se a partir de dois elementos: a propriedade privada e a sua centralidade como mercadoria, expressando-se no território desde sua origem a partir da lógica especulativa. Ao ser assentada sobre território hegemonizado pelo capital, produz entraves profundos para a afirmação do direito à moradia de forma universal. A hipótese que norteia o trabalho é que a questão da moradia, nas suas contradições aparentes, apresenta-se como mais uma solução para a acumulação do capital, conforme contribuição de autores clássicos e contemporâneos do campo da teoria social crítica. Reflete sobre elementos estruturais que desafiam a garantia do direito à moradia em particular no Brasil, sendo que os limites da conformação da questão habitacional e das formas históricas de resposta do Estado no Brasil necessitam ser compreendidas no contexto mais amplo da dinâmica da acumulação

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

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

    The ion mobility spectrometer-mass spectrometer (IMS-MS) is described and consists of two separate instruments coupled in tandem: an ion mobility spectrometer coupled to a quadrupole mass spectrometer. The two insturments operate at different pressures in a synergistic manner, supplying both drift time and mass information about ions which are formed at atmospheric pressure in the ion mobility spectrometer tube. Two types of ion intensity signals are presented to the data processor. The IMS produces an analog voltage with major components from dc to 5 KHz. The mass spectrometer signal output resides in the pulse count rate derived from a series of TTL level pulses where each pulse represents the arrival of a single ion. The hardware, software, interfacing capabilities and basic data acquisition program are described in detail

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

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

    2015-01-01

    The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration in the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability (SSI), Human Systems Integration (HSI), and Communication to support reducing the barriers of UAS access to the NAS. This research was broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Sense and Avoid (SAA) performance standards, command and control performance standards, and human systems integration. The focus of the Test Infrastructure theme was to enable development and validation of airspace integration procedures and performance standards, including the execution of integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project developed an adaptable, scalable, and schedulable relevant test environment incorporating live, virtual, and constructive elements capable of validating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project planned to conduct three integrated events: a Human-in-the-Loop simulation and two Flight Test series that integrated key concepts, technologies and/or procedures in a relevant air traffic environment.

    Backes, Carl H.; Backes, Carl R.; Gardner, Debra; Nankervis, Craig A.; Giannone, Peter J.; Cordero, Leandro

    2013-01-01

    Background Each year in the US approximately 50,000 neonates receive inpatient pharmacotherapy for the treatment of neonatal abstinence syndrome (NAS). Objective To compare the safety and efficacy of a traditional inpatient only approach with a combined inpatient and outpatient methadone treatment program. Design/Methods Retrospective review (2007-9). Infants were born to mothers maintained on methadone or buprenorphine in an antenatal substance abuse program. All infants received methadone for NAS treatment as inpatient. Methadone weaning for the traditional group (75 pts) was inpatient while the combined group (46 pts) was outpatient. Results Infants in the traditional and combined groups were similar in demographics, obstetrical risk factors, birth weight, GA and the incidence of prematurity (34 & 31%). Hospital stay was shorter in the combined than in the traditional group (13 vs 25d; p < 0.01). Although the duration of treatment was longer for infants in the combined group (37 vs 21d, p<0.01), the cumulative methadone dose was similar (3.6 vs 3.1mg/kg, p 0.42). Follow-up: Information was available for 80% of infants in the traditional and 100% of infants in the combined group. All infants in the combined group were seen ≤ 72 hours from hospital discharge. Breast feeding was more common among infants in the combined group (24 vs. 8% p<0.05). Following discharge there were no differences between the two groups in hospital readmissions for NAS. Prematurity (<37w GA) was the only predictor for hospital readmission for NAS in both groups (p 0.02, OR 5). Average hospital cost for each infant in the combined group was $13,817 less than in the traditional group. Conclusions A combined inpatient and outpatient methadone treatment in the management of NAS decreases hospital stay and substantially reduces cost. Additional studies are needed to evaluate the potential long term benefits of the combined approach on infants and their families. PMID:21852772

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

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

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

  2. 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.

  5. An Integrated Gate Turnaround Management Concept Leveraging Big Data Analytics for NAS Performance Improvements

    Science.gov (United States)

    Chung, William W.; Ingram, Carla D.; Ahlquist, Douglas Kurt; Chachad, Girish H.

    2016-01-01

    "Gate Turnaround" plays a key role in the National Air Space (NAS) gate-to-gate performance by receiving aircraft when they reach their destination airport, and delivering aircraft into the NAS upon departing from the gate and subsequent takeoff. The time spent at the gate in meeting the planned departure time is influenced by many factors and often with considerable uncertainties. Uncertainties such as weather, early or late arrivals, disembarking and boarding passengers, unloading/reloading cargo, aircraft logistics/maintenance services and ground handling, traffic in ramp and movement areas for taxi-in and taxi-out, and departure queue management for takeoff are likely encountered on the daily basis. The Integrated Gate Turnaround Management (IGTM) concept is leveraging relevant historical data to support optimization of the gate operations, which include arrival, at the gate, departure based on constraints (e.g., available gates at the arrival, ground crew and equipment for the gate turnaround, and over capacity demand upon departure), and collaborative decision-making. The IGTM concept provides effective information services and decision tools to the stakeholders, such as airline dispatchers, gate agents, airport operators, ramp controllers, and air traffic control (ATC) traffic managers and ground controllers to mitigate uncertainties arising from both nominal and off-nominal airport gate operations. IGTM will provide NAS stakeholders customized decision making tools through a User Interface (UI) by leveraging historical data (Big Data), net-enabled Air Traffic Management (ATM) live data, and analytics according to dependencies among NAS parameters for the stakeholders to manage and optimize the NAS performance in the gate turnaround domain. The application will give stakeholders predictable results based on the past and current NAS performance according to selected decision trees through the UI. The predictable results are generated based on analysis of the

However, few studies have investigated the diversity of environmental nitrate assimilating bacteria (NAB. In this study, the diversity and biogeographical distribution of NAB in several global oceans and particularly in the western Pacific marginal seas were investigated using both cultivation and culture-independent molecular approaches. Phylogenetic analyses based on 16S rRNA and nasA (encoding the large subunit of the assimilatory nitrate reductase gene sequences indicated that the cultivable NAB in South China Sea belonged to the α-Proteobacteria, γ-Proteobacteria and CFB (Cytophaga-Flavobacteria-Bacteroides bacterial groups. In all the environmental samples of the present study, α-Proteobacteria, γ-Proteobacteria and Bacteroidetes were found to be the dominant nasA-harboring bacteria. Almost all of the α-Proteobacteria OTUs were classified into three Roseobacter-like groups (I to III. Clone library analysis revealed previously underestimated nasA diversity; e.g. the nasA gene sequences affiliated with β-Proteobacteria, ε-Proteobacteria and Lentisphaerae were observed in the field investigation for the first time, to the best of our knowledge. The geographical and vertical distributions of seawater nasA-harboring bacteria indicated that NAB were highly diverse and ubiquitously distributed in the studied marginal seas and world oceans. Niche adaptation and separation and/or limited dispersal might mediate the NAB composition and community structure in different water bodies. In the shallow-water Kueishantao hydrothermal vent environment, chemolithoautotrophic sulfur-oxidizing bacteria were the primary NAB, indicating a unique nitrate-assimilating community in this extreme environment. In the coastal water of the East China Sea, the relative abundance of Alteromonas and Roseobacter-like nasA gene sequences responded closely to algal blooms, indicating

    2016-05-27

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

    Full Text Available Quantum Aesthetics phenomenon was formed in Spain, at the end of the twentieth centure. The paper analyzes this movement in the context of Algis Mickūnas phenomenological cosmic philosophy. Movement initiator is a Spanish novelist Gregorio Morales. The study is divided into two parts: the first part presents aesthetic principles of the quantum, relationship between new aesthetics and theories of quantum mechanics, physics and other sciences. The paper also examines the similarities of quantum aesthetics and New Age movements. The second part presents cosmic - phenomenological reflection of quantum theory of beauty. Mickūnas philosophical position combines theory of "eternal recurrence", "the bodily nature of consciousness", "the cosmic dance", theory of "dynamic fields" and quantum approach to aesthetics and the Universe. Summa Summarum he writes that "the conception of quantum aesthetics is involved in the composition of the rhythmic, cyclical and mood dimensioned and tensed world".

    2015-01-01

    We have systematically studied the temperature dependence of incorporation characteristics of nitrogen (N) and indium (In) in growing GaInNAs films. With the implementation of Monte-Carlo simulation, the low N adsorption energy (−0.10 eV) is demonstrated. To understand the atomic incorporation mechanism, temperature dependence of interactions between Group-III and V elements are subsequently discussed. We find that the In incorporation behaviors rather than that of N are more sensitive to the T g , which can be experimentally verified by exploring the compositional modulation and structural changes of the GaInNAs films by means of high-resolution X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscope, and secondary ion mass spectroscopy

    2015-01-01

    Full Text Available Density functional theory (DFT calculations with the local density approximation (LDA functional are employed to investigate the band alignment of dilute-As GaNAs alloys with respect to the GaN alloy. Conduction and valence band positions of dilute-As GaNAs alloy with respect to the GaN alloy on an absolute energy scale are determined from the combination of bulk and surface DFT calculations. The resulting GaN / GaNAs conduction to valence band offset ratio is found as approximately 5:95. Our theoretical finding is in good agreement with experimental observation, indicating the upward movements of valence band at low-As content dilute-As GaNAs are mainly responsible for the drastic reduction of the GaN energy band gap. In addition, type-I band alignment of GaN / GaNAs is suggested as a reasonable approach for future device implementation with dilute-As GaNAs quantum well, and possible type-II quantum well active region can be formed by using InGaN / dilute-As GaNAs heterostructure.

    Yizhakevych, O. M.; Andruk, V. M.; Pakuliak, L. K.

    We present the results of photographic observations' processing of Saturn's moons, Uranus, Neptune and their moons on the basis of MAO NAS of Ukraine photographic observational archive. The analysis of the results is given. Observations were obtained using 4 telescopes: Double Long-Focus Astrograph (DLFA, D/F = 400/5500), Zeiss Double Astrograph (DAZ, D/F= 400/3000), Reflector Zeiss-600 (D/F= 600/7500), Wideangle Astrograph, (DWA, D/F= 400/2000). Observations were carried out during 1961 - 1990 (http://gua.db.ukrvo. org). Digitizing of plates has been done by EPSON EXPRESSION 10000XL (EE) flatbed scanner in 16-bit gray color range with resolution 1200dpi.(Andruk et al.: 2005, 2012; Golovnja et al.: 2010;. Protsyuk et al. 2014a, 2014b). The reduction of plates was made using the software developed in MAO NASU in the enhanced LINUX-MIDAS software kit. (Andruk V. et al.: 2016a, 2016b). Tycho2 was used as a reference system. The internal accuracy of the reduction for the first three instruments is ±0.08 - ±0.13 arcsec for both coordinates. For the wide angle astrograph DWA, RMS errors appeared 2 - 2.5 times higher. The total amount of processed plates with images of Saturn's moons is 209 (511 frames), 33 plates contain the images of Uranus and U1,U2,U3,U4 moons, 29 plates have images of Neptune and N1 moon (Yizhakevych et al., 2015, 2016, 2017; Protsyuk et al., 2015). The online comparison of calculated positions of objects with IMCCE ephemeris data was made (http://lnfm1.sai.msu.ru/neb/nss/nssephmf.htm).

    On July 5, 1994, an IBM Scalable POWER parallel System (IBM SP2) with 64 nodes, was installed at the Numerical Aerodynamic Simulation (NAS) Facility Each node of NAS IBM SP2 is a "wide node" consisting of a RISC 6000/590 workstation module with a clock of 66.5 MHz which can perform four floating point operations per clock with a peak performance of 266 Mflop/s. By the end of 1994, 64 nodes of IBM SP2 will be upgraded to 160 nodes with a peak performance of 42.5 Gflop/s. An overview of the IBM SP2 hardware is presented. The basic understanding of architectural details of RS 6000/590 will help application scientists the porting, optimizing, and tuning of codes from other machines such as the CRAY C90 and the Paragon to the NAS SP2. Optimization techniques such as quad-word loading, effective utilization of two floating point units, and data cache optimization of RS 6000/590 is illustrated, with examples giving performance gains at each optimization step. The conversion of codes using Intel's message passing library NX to codes using native Message Passing Library (MPL) and the Message Passing Interface (NMI) library available on the IBM SP2 is illustrated. In particular, we will present the performance of Fast Fourier Transform (FFT) kernel from NAS Parallel Benchmarks (NPB) under MPL and MPI. We have also optimized some of Fortran BLAS 2 and BLAS 3 routines, e.g., the optimized Fortran DAXPY runs at 175 Mflop/s and optimized Fortran DGEMM runs at 230 Mflop/s per node. The performance of the NPB (Class B) on the IBM SP2 is compared with the CRAY C90, Intel Paragon, TMC CM-5E, and the CRAY T3D.

  6. Functional Requirements Document for HALE UAS Operations in the NAS: Step 1. Version 3

    Science.gov (United States)

    2006-01-01

    The purpose of this Functional Requirements Document (FRD) is to compile the functional requirements needed to achieve the Access 5 Vision of "operating High Altitude, Long Endurance (HALE) Unmanned Aircraft Systems (UAS) routinely, safely, and reliably in the national airspace system (NAS)" for Step 1. These functional requirements could support the development of a minimum set of policies, procedures and standards by the Federal Aviation Administration (FAA) and various standards organizations. It is envisioned that this comprehensive body of work will enable the FAA to establish and approve regulations to govern safe operation of UAS in the NAS on a routine or daily "file and fly" basis. The approach used to derive the functional requirements found within this FRD was to decompose the operational requirements and objectives identified within the Access 5 Concept of Operations (CONOPS) into the functions needed to routinely and safely operate a HALE UAS in the NAS. As a result, four major functional areas evolved to enable routine and safe UAS operations for an on-demand basis in the NAS. These four major functions are: Aviate, Navigate, Communicate, and Avoid Hazards. All of the functional requirements within this document can be directly traceable to one of these four major functions. Some functions, however, are traceable to several, or even all, of these four major functions. These cross-cutting functional requirements support the "Command / Control: function as well as the "Manage Contingencies" function. The requirements associated to these high-level functions and all of their supporting low-level functions are addressed in subsequent sections of this document.

    2017-12-11

    We present a Density Functional Theory (DFT) analysis of the optical properties of dilute-As GaN 1-x As x alloys with arsenic (As) content ranging from 0% up to 12.5%. The real and imaginary parts of the dielectric function are investigated, and the results are compared to experimental and theoretical values for GaN. The analysis extends to present the complex refractive index and the normal-incidence reflectivity. The refractive index difference between GaN and GaNAs alloys can be engineered to be up to ~0.35 in the visible regime by inserting relatively low amounts of As-content into the GaN system. Thus, the analysis elucidates on the birefringence of the dilute-As GaNAs alloys and comparison to other experimentally characterized III-nitride systems is drawn. Our findings indicate the potential of GaNAs alloys for III-nitride based waveguide and photonic circuit design applications.

  11. How discriminating are discriminative instruments?

    Hankins, Matthew

    2008-05-27

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

The next generation of elementary particle physics experiments would depend vitally on new ideas in instrumentation. This is a field where creativity and imagination play a major role and large budgets are not a prerequisite. One of the unique features was the presentation of four laboratory experiments using modern techniques and instrumentation. Refs, figs and tabs

    Radiation protection instruments are used in daily measurement of dose and activities in workplaces and environments for safety management. The requirements for calibration certificates with traceability are increasing for these instruments to ensure the consistency and reliabilities of the measurement results. The present traceability scheme of radiation protection instruments for dose and activity measurements is described with related IEC/ISO requirements. Some examples of desirable future calibration systems with recent new technologies are also discussed to establish the traceability with reasonable costs and reliabilities.

    Admittance spectroscopy has been performed to investigate the effect of antimony (Sb) on GaInNAs material in relation to the deep-level defects in this material. Two electron traps, E1 and E2 at an energy level 0.12 and 0.41 eV below the conduction band (E{sub C}), respectively, were found in undoped GaInNAs. Bias-voltage dependent admittance confirmed that E1 is an interface-type defect being spatially localized at the GaInNAs/GaAs interface, while E2 is a bulk-type defect located around mid-gap of GaInNAs layer. Introduction of Sb improved the material quality which was evident from the reduction of both the interface and bulk-type defects.

    1986-01-01

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

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

    Springston, Stephen R. [Brookhaven National Lab. (BNL), Upton, NY (United States)

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

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

    Full Text Available Abstract Background and objective: NAS is a combination of signs and symptoms that due to physical and mental dependency, develops in neonates born from drug addicted mothers. The onset of NAS varies in accordance with the type, amount, frequency and duration of substance used. Because of diverse and unclear pattern of substance abuse in Iranian addicted pregnant mothers in comparison with western countries, this multi-center study has been designed to evaluate NAS in neonates born from drug addicted mothers. Material and method: A cross sectional study was carried out on newborns of narcotic addicted mothers during the first six months of 2008. The newborn’s status and clinical signs were checked by physical examination and scored by the Finnegan scoring system. Results: In this study 100 neonates born from narcotic addicted mothers were examined; the most used narcotic was crack (36%. 60% of neonates showed signs of NAS. The most prevalent signs of NAS were increased muscle tonicity (60%/7, irritability (59%/6 and increased moro reflex (51%/8. Neonates born from crack abusers, in comparison with other drugs, were significantly at risk of NAS (100% vs.87%, p

    2012-01-01

    As a result of the FAA Modernization and Reform Act of 2012, Unmanned Aerial Systems (UAS) are expected to be integrated into the National Airspace System (NAS) by 2015. Several human factors challenges need to be addressed before UAS can safely and routinely fly in the NAS with manned aircraft. Perhaps the most significant challenge is for the UAS to be non-disruptive to the air traffic management system. Another human factors challenge is how to provide UAS pilots with intuitive traffic information in order to support situation awareness (SA) of their airspace environment as well as a see-and-avoid capability comparable to manned aircraft so that a UAS pilot could safely maneuver the aircraft to maintain separation and collision avoidance if necessary. A simulation experiment was conducted to examine baseline compliance of UAS operations in the current airspace system. Researchers also examined the effects of introducing a Cockpit Situation Display (CSD) into a UAS Ground Control Station (GCS) on UAS pilot performance, workload and situation awareness while flying in a positively controlled sector. Pilots were tasked with conducting a highway patrol police mission with a Medium Altitude Long Endurance (MALE) UAS in L.A. Center airspace with two mission objectives: 1) to reroute the UAS when issued new instructions from their commander, and 2) to communicate with Air Traffic Control (ATC) to negotiate flight plan changes and respond to vectoring and altitude change instructions. Objective aircraft separation data, workload ratings, SA data, and subjective ratings regarding UAS operations in the NAS were collected. Results indicate that UAS pilots were able to comply appropriately with ATC instructions. In addition, the introduction of the CSD improved pilot SA and reduced workload associated with UAS and ATC interactions.

  4. The CAS-NAS forum for new leaders in space science

    Science.gov (United States)

    Smith, David H.

    The space science community is thoroughly international, with numerous nations now capable of launching scientific payloads into space either independently or in concert with others. As such, it is important for national space-science advisory groups to engage with like-minded groups in other spacefaring nations. The Space Studies Board of the US National Academy of Sciences' (NAS') National Research Council has provided scientific and technical advice to NASA for more than 50 years. Over this period, the Board has developed important multilateral and bilateral partnerships with space scientists around the world. The primary multilateral partner is COSPAR, for which the Board serves as the US national committee. The Board's primary bilateral relationship is with the European Science Foundation’s European Space Science Committee. Burgeoning Chinese space activities have resulted in several attempts in the past decade to open a dialogue between the Board and space scientists in China. On each occasion, the external political environment was not conducive to success. The most recent efforts to engage the Chinese space researchers began in 2011 and have proved particularly successful. Although NASA is currently prohibited from engaging in bilateral activities with China, the Board has established a fruitful dialogue with its counterpart in the Chinese Academy of Sciences (CAS). A joint NAS-CAS activity, the Forum for New Leaders in Space Science, has been established to provide opportunities for a highly select group of young space scientists from China and the United States to discuss their research activities in an intimate and collegial environment at meetings to be held in both nations. The presentation will describe the current state of US-China space relations, discuss the goals of the joint NAS-CAS undertaking and report on the activities at the May, 2014, Forum in Beijing and the planning for the November, 2014, Forum in Irvine, California.

Dicha lipólisis es catalizada por la lipoproteína lipasa y se produce en pasos sucesivos, de manera que los productos son heterogéneos. Su concentración plasmática en ayunas es pequeña en pacientes normolipémicos y aumenta en el estado post-prandial. Las alteraciones genéticas en subtipos de su componente Apo-E aumentan notablemente su concentración plasmática y producen el fenotipo de disbetalipoproteinemia. Se las considera aterogénicas porque injurian el endotelio, sufren estrés oxidativo, son captadas por los macrófagos en el subendotelio vascular y generan las células espumosas que son precursoras de ateromas. Su origen metabólico, como productos de varios tipos de lipoproteínas, explican su estructura heterogénea, sus concentraciones plasmáticas variables y las dificultades metodológicas que dificultan su inclusión en el perfil lipoproteico como parte de los estudios epidemiológicos. Los últimos avances en los estudios metabólicos y la actualización de su papel clínico, justifican una revisión de los conocimientos actuales.

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

  12. Photoluminescence and magnetophotoluminescence studies in GaInNAs/GaAs quantum wells

    Science.gov (United States)

    Segura, J.; Garro, N.; Cantarero, A.; Miguel-Sánchez, J.; Guzmán, A.; Hierro, A.

    2007-04-01

    We investigate the effects of electron and hole localization in the emission of a GaInNAs/GaAs single quantum well at low temperatures. Photoluminescence measurements varying the excitation density and under magnetic fields up to 14 T have been carried out. The results indicate that electrons are strongly localized in these systems due to small fluctuations in the nitrogen content of the quaternary alloy. The low linear diamagnetic shift of the emission points out the weakness of the Coulomb correlation between electrons and holes and suggests an additional partial localization of the holes.

    Full Text Available RESUMO O tempo de deslocamento de casa ao trabalho tem se elevado substancialmente nas regiões metropolitanas brasileiras durante a última década. Esse fenômeno tem implicações fortes sobre o bem-estar dos indivíduos, porém as consequências desse problema não se distribuem uniformemente entre a população. O presente trabalho visa contribuir para o debate sobre a questão da mobilidade urbana nas metrópoles brasileiras analisando a evolução do tempo de deslocamento entre 1992 e 2013 e suas diferenças de acordo com características do trabalhador, como sexo, cor e renda per capita , e do posto de trabalho. Verifica-se que o aumento do tempo médio de deslocamento ocorreu a partir de 2003, caracterizando uma questão particularmente importante para as metrópoles brasileiras no terceiro milênio. Os trabalhadores com maiores tempos médios de deslocamento residem nas regiões metropolitanas do Rio de Janeiro e de São Paulo. Entretanto, as maiores taxas de crescimento ocorreram nas metrópoles do Pará, Salvador e Recife, sugerindo a necessidade de melhor direcionamento e planejamento de políticas públicas na mobilidade urbana. Considerando as diferenças socioeconômicas, destaca-se que os mais pobres e os mais ricos (extremos da distribuição de renda tendem a apresentar tempos de deslocamento menores do que os trabalhadores de famílias de renda média. Esse padrão se mantém ao longo do tempo, com aumento do tempo médio de deslocamento entre os mais pobres, mostrando uma face da desigualdade. Porém, o maior aumento ocorreu entre os mais ricos, colocando a questão da mobilidade urbana para além dos problemas de exclusão social.

    High-resolution x-ray diffraction (HRXRD) and photoreflectance (PR) spectroscopy were used to independently determine the In and N concentrations in GaInNAs alloys grown by solid-source molecular beam epitaxy (SSMBE). The lattice constant and bandgap energy can be expressed as two independent equations in terms of the In and N concentrations, respectively. The HRXRD measurement provided the lattice constant and the PR measurement extracted the bandgap energy. By simultaneously solving these two equations, we have determined the In and N concentrations with the error as small as 0.001

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

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

    1994-01-01

    We present views and analysis of the execution of several PVM (Parallel Virtual Machine) codes for Computational Fluid Dynamics on a networks of Sparcstations, including: (1) NAS Parallel Benchmarks CG and MG; (2) a multi-partitioning algorithm for NAS Parallel Benchmark SP; and (3) an overset grid flowsolver. These views and analysis were obtained using our Automated Instrumentation and Monitoring System (AIMS) version 3.0, a toolkit for debugging the performance of PVM programs. We will describe the architecture, operation and application of AIMS. The AIMS toolkit contains: (1) Xinstrument, which can automatically instrument various computational and communication constructs in message-passing parallel programs; (2) Monitor, a library of runtime trace-collection routines; (3) VK (Visual Kernel), an execution-animation tool with source-code clickback; and (4) Tally, a tool for statistical analysis of execution profiles. Currently, Xinstrument can handle C and Fortran 77 programs using PVM 3.2.x; Monitor has been implemented and tested on Sun 4 systems running SunOS 4.1.2; and VK uses XIIR5 and Motif 1.2. Data and views obtained using AIMS clearly illustrate several characteristic features of executing parallel programs on networked workstations: (1) the impact of long message latencies; (2) the impact of multiprogramming overheads and associated load imbalance; (3) cache and virtual-memory effects; and (4) significant skews between workstation clocks. Interestingly, AIMS can compensate for constant skew (zero drift) by calibrating the skew between a parent and its spawned children. In addition, AIMS' skew-compensation algorithm can adjust timestamps in a way that eliminates physically impossible communications (e.g., messages going backwards in time). Our current efforts are directed toward creating new views to explain the observed performance of PVM programs. Some of the features planned for the near future include: (1) ConfigView, showing the physical topology

    2015-01-01

    The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration into the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability, Human Systems Integration (HSI), and Communication to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Sense and Avoid (SAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including the integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project will conduct a series of Human-in-the-Loop and Flight Test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity and complexity of the previous tests and

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

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

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

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

    Control and instrumentation systems have seen significant changes from pneumatic to electronic with the advent of transistors and integrated circuits. Miniaturization was realised. With the introduction of microprocessors there has been a revolutionary change in the approach in instrumentation and control systems in the areas of sensors, data acquisition/transmission, processing for control, and presentation of the information to the operator. An effort is made to give some insight into these areas, with some idea of the advantages to which these systems are being put to use in the nuclear facilities, particularly nuclear power reactors.

    Full Text Available O comportamento proativo é definido como um conjunto de comportamentos extrapapel em que o trabalhador busca espontaneamente mudanças no seu ambiente de trabalho, soluciona e antecipa-se aos problemas, visando a metas de longo prazo que beneficiam a organização. Este estudo teve por objetivo investigar a relação entre os valores pessoais e o comportamento proativo nas organizações. Foram utilizados como instrumentos de medida o Personal Values Questionnaire e a Escala de Comportamento Proativo nas Organizações, ambos já validados para o Brasil. Após a eliminação dos casos extremos, a amostra ficou constituída por 325 funcionários de diferentes organizações. A análise de regressão linear revelou que os valores predizem significativamente os comportamentos proativos, apontando uma relação positiva do tipo motivacional estimulação (B= 0,205, p<0,01 e universalismo/benevolência (B=0,302, p<0,01 com proatividade, e negativa com o tipo motivacional tradição (B= -0,189, p<0,01, de acordo com o previsto pelo referencial teórico. As implicações para os estudos na área são discutidas.

    Full Text Available http://dx.doi.org/10.5007/2175-7968.2013v1n31p103 O objetivo deste artigo é discutir as narrativas indianas nas línguas bhashas, as línguas vernáculas do subcontinente indiano a través de uma política e poética da tradução que da voz e visibilidade a culturas que, de outro modo, estariam restringidas às diversas culturas onde são produzidas. Dessa maneira, não só as literaturas do “front yard”, ou seja as narrativas indianas escritas na língua inglesa da diáspora ganham visibilidade, mas também as narrativas escritas do “backyard” nas línguas vernáculas  da Índia. Nesse processo, o termo “vernáculo” ganha um novo significado no sentido que o que é realmente “vernacularizado” é a língua  inglesa porque se torna um veículo por meio do que as literaturas bhasha tornam-se conhecidas. Para ilustrar esse processo o artigo traz uma análise do conto “Thayyaal” escrito na língua Tamil, do sul da Índia.

Essas tensões dizem respeito ao golpe militar que inibiu melhorias no setor educacional, ao estudo exclusivo nas escolas de obras consideradas canônicas e ao estudo conteudista de literatura exigido pelos exames vestibulares. Esse é um debate importante, pois o ensino atual de literatura nas escolas impede a formação de estudantes capazes de analisar e interpretar um texto literário e de compreender o contexto histórico e sociológico de um país. Iremos, portanto, detalhar esses problemas e apresentaremos como o ensino de literatura brasileira pode ser importante para a percepção por parte dos alunos dos problemas sociais e consequentemente criar estudantes críticos.

Pautado no conceito de experiência (MICCOLI, 2010, buscamos compreender quais experiências emergem dessas narrativas e como elas influenciam na prática de ensino dos professores. Ademais, intentamos analisar como os professores de Inglês se veem e quais desafios ele enfrentam nos seus contextos de trabalho. Os resultados desse estudo mostraram que, apesar de todas as experiências de dificuldades e indisciplina reveladas nas narrativas, duas delas parecem ainda encontrar motivação e esperança quanto à sua profissão. Além disso, percebemos que o modo como os professores veem sua realidade, seus alunos e seu trabalho são importantes para caracterizar sua prática profissional. Assim, acreditamos que o contexto e as experiências retratados nas narrativas podem ser caminhos que direcionem as ações desses professores em sala de aula e, consequentemente, possibilitem reflexões e mudanças no seu papel como educador.

    Full Text Available Partindo do pressuposto de que a teoria social elaborada por Habermas em muito se assemelha àquela construída por M. Weber, procedeu-se a um estudo comparativo com a intenção de identificar as formas pelas quais Weber e Habermas elaboraram o conceito de compreensão, ao mesmo tempo em que e o elegeram, cada um a seu modo, como instrumento metodológico adequado às dificuldades da produção de conhecimento científico nas Ciências Sociais. Tanto para Weber, como para Habermas, o conhecimento nas Ciências Sociais não consegue escapar das influências diretas da subjetividade do cientista, como também não é capaz de se proteger das contingências histórico-culturais aos quais inevitavelmente toda ação humana está vinculada. Por isso, fundamentados em suas próprias razões, tanto Weber quanto Habermas apontam a compreensão como a forma possível de conhecimento, o que implica a renúncia às pretensões explicativas e à produção de teorias gerais de fundamentação última, que são típicas das ciências convencionais.

    Full Text Available This study aims to analyse the process of harmonization of national accounting standards of the Republic of Moldova to the international standards. It highlights the main advantages, disadvantages, risks and opportunities regarding the implementation of the new standards. A major step for the Republic of Moldova was the implementation of IFRS, which has become mandatory for all public interest entities from 1 January 2012 and the adoption of new NAS in accordance with EU Directives and IFRS for small and medium-sized entities, for which the transition to IFRS was difficult due to high costs involved. The new NAS came into force on 1 January 2014 as a recommendation, but starting with 1st January 2015 it will be mandatory for all entities. The paper includes a practical analysis of the impact of transition to IFRS on the financial results of a public interest entity- Moldova Agroindbank, which is the largest commercial bank, with the highest market share in the banking sector of the Republic of Moldova. A result of the analysis of primary and secondary indicators calculated on the base of the financial statements prepared by commercial bank at 31.12.11, we found that the transition to IFRS has resulted in the growth of all financial indicators.

    In the Main Astronomical Observatory of NAS of Ukraine is proposed and implemented the concept of the imaging Stokes polarimeter [1-5]. This device allows carrying out measurements of the four Stokes vector components at the same time, in a wide field, and without any restrictions on the relative aperture of the optical system. Its scheme is developed so that only by turning wheel with replaceable elements, photopolarimeter could be transformed into a low resolution spectropolarimeter. The device has four film's polarizers with positional angles 0°, 45°, 90°, 135°. The device uses a system of special deflecting prisms in each channel. These prisms were achromatizing in the spectral range of 420-850 nm [2], the distortion of the polarimeter optical system is less than 0.65%. In manufacturing version of spectropolarimeter provided for the possibility of using working on passing the diffraction grating with a frequency up to 100 lines/mm. Has begun the laboratory testing of instrument. References. 1. Sinyavskii I.I., Ivanov Yu. S., Vidmachenko Anatoliy P., Karpov N.V.

    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.

    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 1 fig., 1 tab

For comparison purposes, the tests were also run on Lomax, a 400 MHz Origin 2000 with R12K processors. The BT, LU, and SP application benchmarks in the NAS Parallel Benchmark Suite and the kernel benchmark FT were chosen to measure system performance. Having been written to measure performance on Computational Fluid Dynamics applications, these benchmarks are assumed appropriate to represent the NAS workload. Since the NAS runs both message passing (MPI) and shared-memory, compiler directive type codes, both MPI and OpenMP versions of the benchmarks were used. The MPI versions used were the latest official release of the NAS Parallel Benchmarks, version 2.3. The OpenMP versions used were PBN3b2, a beta version that is in the process of being released. NPB 2.3 and PBN3b2 are technically different benchmarks, and NPB results are not directly comparable to PBN results.

    To understand microscopic mechanisms of charge and discharge reactions in Na-S batteries, there has been increasing needs to study fundamental atomic and electronic structures of elemental S as well as that of Na-S phases. The most stable form of S is known to be an orthorhombic α-S crystal at ambient temperature and pressure, and α-S consists of puckered S8 rings which crystallize in space group Fddd . In this study, the crystal structure of α-S is examined by using first-principles calculations with and without the van der Waals interaction corrections of Grimme's method, and results clearly show that the van der Waals interactions between the S8 rings have crucial roles on cohesion of α-S. We also study structure stabilities of Na2S, NaS, NaS2, and Na2S5 phases with reported crystal structures. Using calculated total energies of the crystal structure models, we estimate discharge voltages assuming discharge reactions from 2Na+ xS -->Na2Sx, and discharge reactions in Na/S battery systems are discussed by comparing with experimental results.

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

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

    Incremental approaches to air transportation system development inherit current architectural constraints, which, in turn, place hard bounds on system capacity, efficiency of performance, and complexity. To enable airspace operations of the future, a clean-slate (ab initio) airspace design(s) must be considered. This ab initio National Airspace System (NAS) must be capable of accommodating increased traffic density, a broader diversity of aircraft, and on-demand mobility. System and subsystem designs should scale to accommodate the inevitable demand for airspace services that include large numbers of autonomous Unmanned Aerial Vehicles and a paradigm shift in general aviation (e.g., personal air vehicles) in addition to more traditional aerial vehicles such as commercial jetliners and weather balloons. The complex and adaptive nature of ab initio designs for the future NAS requires new approaches to validation, adding a significant physical experimentation component to analytical and simulation tools. In addition to software modeling and simulation, the ability to exercise system solutions in a flight environment will be an essential aspect of validation. The NASA Langley Research Center (LaRC) Autonomy Incubator seeks to develop a flight simulation infrastructure for ab initio modeling and simulation that assumes no specific NAS architecture and models vehicle-to-vehicle behavior to examine interactions and emergent behaviors among hundreds of intelligent aerial agents exhibiting collaborative, cooperative, coordinative, selfish, and malicious behaviors. The air transportation system of the future will be a complex adaptive system (CAS) characterized by complex and sometimes unpredictable (or unpredicted) behaviors that result from temporal and spatial interactions among large numbers of participants. A CAS not only evolves with a changing environment and adapts to it, it is closely coupled to all systems that constitute the environment. Thus, the ecosystem that

    Full Text Available This work is focused on the development of o/w salad dressing-type emulsions stabilized by tuna proteins. The influence of protein conservation methods after the extraction process (freezing or liofilization on the rheological properties and microstructure of these emulsions was analyzed. Processing variables during emulsification were also evaluated. Stable emulsions with adequate rheological and microstructural characteristics were prepared using 70% oil and 0.50% tuna proteins. From the experimental results obtained, we may conclude that emulsion rheological properties are not significantly affected by the protein conservation method selected. On the contrary, an increase in homogenization speed favours an increase in the values of the linear viscoelastic functions. Less significant is the fact that as agitation speed increases further, mean droplet size steadily decreases.

    El presente trabajo se ha centrado en el desarrollo de emulsiones alimentarias aceite-en-agua estabilizadas con proteínas de atún. Específicamente, se ha analizado la influencia del método de conservación de las proteínas aisladas (liofilización, congelación y de las condiciones de procesado seleccionadas sobre el comportamiento reológico y la microestructura de dichas emulsiones. Se han preparado emulsiones aceite en agua (con un contenido del 70% en peso de aceite estabilizadas con proteínas de atún. La concentración de emulsionante usada ha sido 0,50% en peso. El comportamiento reológico de estas emulsiones no depende significativamente del método de conservación de la proteína empleado. Por otra parte, un aumento de la velocidad de agitación durante el proceso de manufactura de la emulsión da lugar a una disminución continua del tamaño medio de gota y a un aumento de las funciones viscoelásticas dinámicas, menos significativo a medida que aumenta dicha velocidad de agitación.

    Full Text Available Introdução: é tema atual a realização de procedimentos cirúrgicos por minitoracotomias que, inicialmente utilizadas para operações de revascularização do miocárdio, têm sido também propostas como acesso às operações valvares. O objetivo deste trabalho é analisar resultados da minitoracotomia em relação à técnica tradicional nas intervenções valvares, em estudo prospectivo. Casuística e métodos: entre novembro de 1996 e fevereiro de 1998, dois grupos, 8 pacientes operados por minitoracotomia (Grupo 1 e 8 controles (Grupo 2 equiparáveis nas variáveis sexo, idade, peso/altura, classe funcional pré-operatória, doença de base e operação proposta, foram submetidos a reparo ou troca valvar aórtica ou mitral. Os pacientes do Grupo 1 foram operados através de incisão paraesternal direita de até 8 cm, com circulação extracorpórea (CEC estabelecida através de canulação arterial e venosa femorais e os do Grupo 2 (controles por esternotomia mediana. Ambos os grupos foram acompanhados até a alta hospitalar. Resultados: Os parâmetros avaliados no trans-operatório e pós-operatório, bem como a análise estatística constam nas Tabelas 1 e 2. Não ocorreram óbitos imediatos. Duas complicações foram registradas: um infarto per-operatório e um acidente vascular cerebral no Grupo 2. Conclusão: os resultados parciais permitem inferir que a abordagem através de pequenas toracotomias é factível sem aumento na morbimortalidade, do tempo cirúrgico ou da estadia hospitalar. Possíveis vantagens objetivas de um método em relação a outro, exceto o aspecto estético, não estão evidentes até esta etapa do estudo.

    Spectroscopic studies have been carried out on the quantum levels in GaInNAs/GaAs single quantum wells (SQWs). Photoluminescence (PL), PL excitation (PLE), photoreflectance (PR), and high-density-excited PL (HDE-PL) were measured on high quality GaInNAs SQWs, Ga 0.65 In 0.35 N 0.01 As 0.99 /GaAs (well thickness: l z =10 nm) and Ga 0.65 In 0.35 N 0.005 As 0.995 /GaAs (l z =3∝10 nm), grown by molecular-beam epitaxy. For Ga 0.65 In 0.35 N 0.01 As 0.99 /GaAs (l z =10 nm), PL at 8 K exhibited a peak at 1.07 eV due to the exciton-related transition between quantum levels of ground states (e1-hh1). Both PR and PLE exhibited three transitions (1.17, 1.20 and 1.32 eV), and the former two transitions were assigned to as either of e1-lh1 and e2-hh2 transitions, while the transition at 1.32 eV was assigned to as the e2-lh2 transition. For HDE-PL, a new PL peak was observed at about 1.2 eV, and it was assigned to the unresolved e1-lh1 and e2-hh2 transitions. Similar optical measurements have been done on the Ga 0.65 In 0.35 N 0.005 As 0.995 /GaAs with various l z (3∝10 nm). Dependence of optical spectra and energies of quantum levels on l z have been studied. It has been found that HDE-PL in combination with PLE is a good tool for the study of the quantum level of GaInNAs SQW. (copyright 2006 WILEY-VCH Verlag GmbH and Co.

  11. The history of thoracic surgical instruments and instrumentation.

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

    2014-01-01

    The LaSRS++ high-fidelity vehicle simulation was extended in 2012 to support a NAS-wide simulation mode. Since the initial proof-of-concept, the LaSRS++ NAS-wide simulation is maturing into a research-ready tool. A primary benefit of this new capability is the consolidation of the two modeling paradigms under a single framework to save cost, facilitate iterative concept testing between the two tools, and to promote communication and model sharing between user communities at Langley. Specific benefits of each type of modeling are discussed along with the expected benefits of the unified framework. Current capability details of the LaSRS++ NAS-wide simulations are provided, including the visualization tool, live data interface, trajectory generators, terminal routing for arrivals and departures, maneuvering, re-routing, navigation, winds, and turbulence. The plan for future development is also described.

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

    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
