    The present work shows the implementation of the scheme of predictive control IMC (Internal Model Control) in order to control the level of the deareador of a combined cycle thermoelectric power station of (C.C.T.S.). The implementation has the purpose of looking for alternative strategies of control to the classic ones (PID`s) that more efficiently control the variables of interest, in addition to getting into the new control techniques of control. Following the philosophy of predictive control IMC the form to applying this technique is shown, as well as the implementation of this type of controllers. A comparison of predictive control IMC is made with the scheme of conventional control (three control elements PID`s ) used at present to control the level of the deareador in the Combined Cycle Thermoelectric Power stations of Dos Bocas, Veracruz, Mexico and of Gomez Palacio, Durango, Mexico.

    1995-02-01

    Tetrachlorohydroquinone (TCHQ) was determined by two methods: iodometry and cerimetry. Tritation with aqueous ceric ammonium sulphate using potentiometric end-point detection proved to be the method of choice on account of its coefficient of variation (CV=0.475%) and its excellent accuracy. Chloranil (TCQ) was quantified by titration with aqueous ascorbic acid in acetone-water-hexamethylene tetramine (HMT), the golden-yellow color of the TCQ-HMT complex disappearing at the end point. This method is accurate and has CV=0.396%. [Spanish] Se cuantifico la tetraclorohidroquinona (TCHQ) mediante una tecnica yodometrica y un metodo potenciometrico, basado en el uso de sulfato cerico amoniacal. Se concluyo que el metodo potenciometrico es el mejor, ya que tiene un coeficiente de variacion (CV) de 0.475%, y una exactitud muy aceptable. Se desarrollo un tecnica para cuantificar el Cloranilo (TCQ) por titulacion con Acido Ascorbico en presencia de Hexametilentetramina (HMT) en medio acetona-agua; el punto final se determino por la separacion del color amarillo oro del complejo TCQ-HMT. Esta tecnica presenta un coeficiente de variacion (CV) de 0.396% y una exactitud aceptable. Se realizaron pruebas de hipotesis para verificar la exactitud de los metodos elegidos.

    2010-06-01

    Full Text Available Encontra-se espalhada pela obra de Kant uma série de teses que dizem respeito ao que hoje é conhecido por hermenêutica, isto é, a arte ou a técnica da interpretação. Apesar da clara e marcante influência dessas teses sobre Fr. Schlegel e Schleiermacher, que devem ser reconhecidos como os verdadeiros fundadores da hermenêutica moderna, elas não são devidamente levadas em consideração pelos historiadores da hermenêutica. O presente trabalho visa recuperar a memória histórica destas conexões, no intuito de chegar a uma imagem mais justa do desenvolvimento da hermenêutica moderna.There are throughout Kant's work many propositions concerning to what is today called hermeneutics, i. e., the art or the technique of interpretation. Notwithstanding the clear influence of these propositions on Fr. Schlegel and Schleiermacher, who should be recognized as the founders of modern hermeneutics, they aren't duly taken in account by the historians of hermeneutics. The present paper proposes to recover the historical memory of these connections, in order to attain a fair picture of the development of modern hermeneutics.

    Full Text Available Recibido 23 de marzo de 2009 • Aceptado 29 de abril de 2009 • Corregido 28 de julio de 2009   En la actualidad, el gerente educativo, o director, dispone de una serie de herramientas de la administración moderna que permiten guiar la institución educativa hacia la calidad. Para ello, debe cumplir con una serie de funciones que se enmarcan dentro del proceso administrativo, tales como: planear, organizar, dirigir y controlar las actividades del centro a educativo. Este escrito tiene como objetivo dar a conocer algunos de estos aportes y la manera en que el gerente educativo puede utilizarlos para mejorar la institución educativa. La administración moderna pone a disposición de éste diferentes concepciones, que ayudan a visualizar la forma en que se debe gerenciar la institución. La principal conclusión que se extrae es que no existe un cuerpo teórico único que garantice el éxito a un gerente educativo, sino que se debe utilizar lo mejor de cada una de las concepciones que aporta la administración moderna, y adaptarlas, de acuerdo con las circunstancias.

    Full Text Available Este artigo teve como objetivo compreender as formas de controle invisível apresentadas nas organizações modernas e pós-modernas, tendo como ponto de partida a cultura organizacional. Deste modo, um ensaio teórico foi realizado buscando respostas na relação da cultura organizacional com os mecanismos de controle, dentre eles foram abordados a burocracia, poder, ideologia e mediação. Dos resultados, obteve-se que as formas de dominação e controle social apresentam-se tanto na modernidade como na pós-modernidade, fazendo uma transição criativa dos artifícios de controle, enquanto na organização burocrática os controles invisíveis estão nos aspectos formais, como manuais e regulamentos, nas pós-burocráticas os controles são internalizados pelos indivíduos pelos valores compartilhados e pelos pressupostos básicos, ou seja, tornando-se cada vez mais inconscientes.

    Full Text Available L'elettronica reca un contributo essenziale alla tecnica
    aerospaziale in ogni fase di qualsiasi sua realizzazione.
    In fase di progetto è fondamentale l'impiego del calcolo analogico o
    digitale, di quello analogico-digitale e delle tecniche di simulazione.
    Nel volo spaziale la guida e la stabilizzazione si basano sull'uso di
    sistemi elettronici che sono anche impiegati largamente nella essenziale fase
    di preparazione al volo.
    Così pure le comunicazioni coi passeggeri e le telemisure sono possibili
    soltanto grazie all'impiego delle tecniche più avanzate delle telecomunicazioni.
    Si esamina infine la situazione attuale per ciò che si riferisce al grado
    di affidamento delle apparecchiature elettroniche in conseguenza della loro
    crescente complessità: l'impiego di elementi allo stato solido e di adeguate
    tecniche circuitali consente di conservarlo ad un valore accettabile nonostante
    la crescente complicazione degli apparati in conseguenza delle sempre più

    2000-09-01

    Full Text Available Os enfoques administrativos oriundos da modernidade estão, cada vez mais, se tornando obsoletos face às necessidades das organizações, sobretudo, daquelas prestadoras de serviços como é o caso das instituições de saúde, bem como de seu capital humano. Sendo a racionalidade o elemento essencial na consecução dos objetivos organizacionais, a ética moderna exige apenas que os trabalhadores se ajustem aos cargos descritos e às normas de desempenho no cumprimento de suas tarefas. A pós-modernidade é caracterizada pela saturação de informação e consumo, pelo prazer de usar bens e serviços, pela ausência de valores e de sentido para a vida, refletindo a apatia pós-moderna. Sem projetos, a vida interior do homem é sem substância. As organizações de saúde estão sofrendo fortes influências deste contexto. Nesse sentido, a ética precisa ser tratada de maneira nova. Assim sendo, nosso propósito é abordar a liderança da enfermeira à luz da ética pós-moderna.

  10. A metafísica na ciência moderna: uma discussão heideggeriana

    Directory of Open Access Journals (Sweden)

    Flávio Oliveira Silva

    2015-07-01

    Full Text Available O artigo apresenta duas teses de Heidegger: a interpretação da Crítica da Razão Pura como metafísica e a afirmação da permanência da metafísica na ciência moderna. Em seguida analisa as objeções que Loparic apresenta a essas teses no artigo A metafísica e o processo de objetificação,para enfim argumentar que suas contestações não se sustentam. Loparic afirma que  a Crítica da Razão Pura não se destina a investigar a quididade dos entes, mas as condições nas quais os juízos sintéticos a priori podem ser verdadeiros ou falsos, de modo que o problema tratado por Kant não seria ontológico, mas semântico. Loparic afirma ainda que a ciência moderna deixou o quadro ontológico da metafísica aristotélica, na medida em que não mais se destina a estudar os entes como tais, isto é, como uma coisa em si, mas tão somente investigar a resposta da natureza, mediante intervenção técnica no curso dos processos naturais e, portanto não há sequer resquício da metafísica na ciência moderna. Essas objeções apresentam dificuldades na medida em que o autor se utiliza do conceito tradicional de metafísica para tratar da filosofia de Heidegger. Argumenta-se que o sentido de metafísica para Heidegger não se restringe à concepção de metafísica da tradição, de modo que, constitui um equívoco analisar as teses heideggerianas em conformidade com a leitura da tradição.  Heidegger se pauta na indicação de que Kant se ocupa das condições de possibilidade da compreensão, isto é, do Dasein, enquanto o ente que coloca a pergunta sobre o ser e é nesta dimensão que a Crítica da Razão Pura é recepcionada como metafísica. No tocante à ciência, o filósofo afirma que, mesmo a ciência moderna tendo abandonado a representação de objetos, ela não renunciou e nem poderia renunciar à necessidade de a natureza fornecer dados que se possa calcular e de continuar sendo um sistema disponível de informação, de modo

    La medicina premoderna se ocupó tempranamente de la locura. Sin embargo, no supo proporcionar un concepto sólido de enfermedad mental a la psiquiatría naciente, que permaneció atrapada en las contradicciones de la forma sujeto moderna con la que nace. Este texto reconstruye algunos conceptos básicos de la medicina premoderna para mostrar cómo dan expresión metafórica a ciertas características de la estructura ontológica humana necesarias para comprender la enfermedad mental: escisión, individ...

  16. Algunas reflexiones acerca de cuestiones de método, inmanencia y evidencia en la filosofía moderna

    Directory of Open Access Journals (Sweden)

    Gustavo SARMIENTO

    2014-03-01

    Full Text Available En este trabajo se expone una crítica a la perspectiva de la conciencia, propia de la filosofía moderna: A partir de una errada interpretación del método de las matemáticas, Descartes y la filosofía moderna piensan que el conocimiento filosófico cierto se basa en la evidencia de un principio, la del yo existo, lo evidente dado a ese yo, más lo que se siga de ello. Como consecuencia de este error inicial, la doctrina moderna de la percepción sensible reduce toda la inmediatez del ente dado al cognoscente humano a la inmediatez de lo dado a la percepción sensible, negando que pueda haber otra inmediatez, entendida como la ausencia de representaciones, en la relación del hombre con las cosas, entre las cuales él estaría. Con esto, solo quedan el yo reducido a conciencia y sus representaciones y se niega el conocimiento inmediato de las cosas mismas, desembocando en la doctrina de la inmanencia de la conciencia.

    Full Text Available No início do século XX, o campo das artes vive uma saudável reconfiguração e, nas artes brasileiras, a Semana de Arte Moderna, em 1922, evidencia a necessidade de absorção de novos valores estéticos, porém estas reformulações deveriam torná-las autenticamente nacionais. A fotografia não fez parte da semana, e, sua ausência é um indicativo de certo distanciamento que ela teve durante sua evolução dentro do campo das artes. Mais tarde, porém, com o advento dos fotoclubes, ela pode se inserir em tal contexto, conectando-se com a ideia de modernidade. Este artigo pretende apresentar os primeiros passos daquilo que podemos chamar de fotografia moderna, e para tanto, apresentaremos dois dos seus principais nomes, Thomaz Farkas e José Oiticica Filho.

    Koyré, Alexandre

    1992-01-01

    I temi affrontati in questo libro da uno dei più autorevoli storici della scienza, Alexandre Koyré, sono oggetto di un vivace interesse da parte della nostra cultura. Koyré discute qui l'origine, la natura e la valutazione delle macchine e degli strumenti scientifici, considerati nei loro riflessi umani e sociali, più ancora che nelle loro caratteristiche tecniche. La sua analisi chiarisce i termini di alcune questioni fondamentali per la storia della tecnologia e della scienza, e del loro rapporto storico; perché ad esempio la scienza greca, scopritrice di fondamentali principi poi applicati trionfalmente dalla fisica moderna, non abbia cercato di tradurli in innovazioni tecniche; perché i notevolissimi ritrovati tecnici delle civiltà orientali e del Medioevo abbiano fallito a questo scopo; perché la rivoluzione scientifica dell'età moderna ci abbia dato col suo concetto dell'esperienza gli strumenti che sono alla base della civiltà industriale; quale sia infine il rapporto tra tecnica e scienza pu...

    Goldstein, Herbert

    1971-01-01

    Un corso avanzato di Meccanica classica ha costituito, per lungo tempo, una parte importante del curriculum di studi per la laurea in Fisica; al giorno d'oggi però si potrebbe metterne in dubbio la funzionalità. Questo tipo di corso infatti non introduce alcun concetto fisico nuovo e non porta lo studente a contatto diretto con la problematica corrente della ricerca fisica, né lo aiuta, sostanzialmente, a risolvere i problemi pratici di Meccanica che incontra in laboratorio. Ciò nonostante, la Meccanica classica resta parte indispensabile del bagaglio culturale di un fisico. Essa gioca un duplice ruolo nel preparare lo studente allo studio della Fisica moderna. In primo luogo, la Meccanica classica, nell'una o nell'altra delle sue formulazioni più avanzate, serve come trampolino per i diversi rami della Fisica moderna. Così, la tecnica delle variabili azione-angolo risulta necessaria nella vecchia teoria dei quanti, l'equazione di Hamilton-Jacobi e il principio di minima azione forniscono la base per il...

    Directory of Open Access Journals (Sweden)

    Bosco, Michele

    2014-02-01

    Full Text Available Da oltre un ventennio, il tema della guerra da corsa e quello del commercio dei captivi nel Mediterraneo di età moderna, ad esso strettamente connesso, sono oggetto di rinnovato interesse da parte della storiografia internazionale. Soprattutto in Italia, Spagna e Francia (ma anche altrove, ricerche sistematiche hanno permesso di ricostruire diversi aspetti della schiavitù nel Mediterraneo di età moderna: modalità della cattura, condizioni di vita dei prigionieri, riscatti, conversioni. Non solo storici, ma anche antropologi, economisti, storici delle religioni e del diritto hanno dato il loro contributo alla ricerca, tradottosi in raccolte di saggi o in volumi monografici; tale abbondante produzione ha innanzitutto mostrato chiaramente come la guerra da corsa e il commercio dei captivi abbiano rappresentato a lungo un elemento cruciale della storia dei paesi che si affacciano sul Mediterraneo, dal medioevo all’età moderna, giungendo fino ai primi decenni del secolo XIX. Nelle prossime pagine proveremo a ricostruire, a grandi linee, l’evoluzione del dibattito storiografico sull’argomento, in modo da far emergere le questioni ancora aperte e di individuare nuovi possibili percorsi di indagine, che sfruttino in particolare le serie documentarie ancora scarsamente utilizzate o meritevoli di ulteriori ricerche.

    Directory of Open Access Journals (Sweden)

    Nicolás Olszevicki

    2017-07-01

    Full Text Available En este artículo, analizamos la distancia que separa el supuesto proyecto novelístico de Denis Diderot, esbozado en su « Éloge de Richardson » (1762, de su praxis concreta como novelista. En primera instancia, reconstruimos el lugar excéntrico que ocupa la novela en el pensamiento del philosophe y las dificultades a las que se enfrenta la crítica para comprender sus usos. Luego, argumentamos que la puesta en crisis de esa forma narrativa por parte del codirector de la Encyclopédie, específicamente en Jacques le fataliste et son maître (publicada por primera vez de manera completa póstumamente, en 1796,  no apunta solo contra formas perimidas del roman a la usanza medieval y temprano-moderna, como podría sugerir una lectura del « Éloge » qua poética del autor, sino, incluso, contra el propio género que ese texto vindica, la novela sentimental. Esta crítica se ilumina si se la lee en consonancia con las propuestas epistemológicas a la vez escépticas y eclécticas que, desde fines de la década del 40, Diderot defiende, y permite rescatar a nuestro autor como un ineludible precursor, a menudo soslayado, de la novelística moderna.

    Full Text Available Il contributo presenta in modo sintetico il quadro concettuale all'interno del quale uno studio dei prezzi dei libri nella prima età moderna dovrebbe muoversi, così come i problemi metodologici da affrontare. Nonostante la natura di manufatto semi-industriale ponga il libro a stampa in una classe merceologica del tutto particolare nell'economia pre-industriale, è possibile utilizzare le categorie generali di domanda e offerta per identificare alcuni fattori atti ad impostare specifici percorsi di ricerca basati sull'analisi storico-economica. La storia del libro può essere quindi messa in relazione con alcuni temi classici della storia economica, allo scopo di inserire il problema del commercio librario e dei prezzi dei libri in un dibattito storiografico più ampio. Tra le fonti disponibili per lo studio dei prezzi dei libri nella prima età moderna, l'inventario di bottega di Bernardo Giunti (Department of Special Collections, UCLA, Collection 170/622 è una chiara testimonianza del fiorente mercato librario allora esistente a Venezia. Le quasi 12.000 registrazioni incluse nella lista dei libri in vendita riflettono gli scopi e gli obiettivi dell’azienda. La struttura di questo documento è decisamente complessa, frutto di più di venti anni di uso continuo (1600-1620 c.. Lungo questo periodo di tempo, il documento sembra essere evoluto da un semplice elenco o catalogo ad uso del personale interno a un importante strumento per la gestione della bottega e del suo magazzino.

    The effect of temperature and processing time during post-oxidation on hardness and corrosion resistance of AISI 1045 samples treated through nitriding and post-oxidation in a pulsed plasma discharge is evaluated in this paper. Also, a comparative analysis of the mechanical properties obtained with the dual nitriding - post oxidation process versus those properties of typical hard chrome coatings was performed with an aim to propose an alternative technique to the processes of galvanic coatings. The latter revealed that the process of ion nitriding and post-oxidation provides similar properties in hardness and improves the corrosion resistance compared to the hard chrome case. It is conclude that the technique of ion nitriding and post-oxidation is a non environmental harmful technology with strong potential to replace highly polluting electroplating techniques for application of hard chrome coatings. [Spanish] En el presente trabajo se evalua el efecto del tiempo y la temperatura de post-oxidacion sobre las propiedades de dureza y resistencia a la corrosion de muestras de acero AISI 1045 sometido al proceso de nitruracion post-oxidacion ionica en plasmas pulsados. Asi mismo, con el objetivo de fundamentar la propuesta de utilizacion de la nitruracion post-oxidacion ionica como una tecnica alternativa a los procesos galvanicos para aplicacion de recubrimientos de cromo duro, se realizo un analisis comparativo de propiedades, evidenciando que, mediante el proceso nitruracion postoxidacion ionica, es posible obtener caracteristicas similares en dureza y mejores en resistencia a la corrosion que las tipicas obtenidas para el cromo duro. Los resultados obtenidos permiten postular una tecnica que no dana al medio ambiente, como lo es la nitruracion post-oxidacion ionica, como candidata potencial para sustituir las tecnicas galvanicas altamente contaminantes para aplicacion de cromo duro.

Si bien dicha disciplina se expresó de diversas formas en los países desarrollados, al paso de los años y gracias a trabajos teóricos y prácticos de ingenieros y arquitectos alemanes, fue adquiriendo una estructura, objetivos y metodologías propias. Esos profesionales finalmente formaron toda una escuela que trascendió a otros países, para sentar las bases del movimiento llamado planeación moderna de ciudades, al cual se plegaron quienes orientaron las primeras acciones de planeación en ciudades mexicanas, desde los inicios del siglo XX.

    O objetivo deste trabalho é analisar as relações entre o funk carioca enquanto gênero musical e a teoria sobre as condições de uma economia política moderna no estágio contemporâneo, em que a acumulação flexível e os rápidos giros nos ciclos do capital se desdobram em uma sociabilidade e em aspectos culturais de mobilidade, risco, incerteza, crise, fluidez, portabilidade e interconexão. O referencial teórico é baseado principalmente nas obras de Harvey (2006, Lyotard (2003 e Anderson (1999. A primeira seção discute, com base nestes autores, a conjuntura pós-moderna; a segunda apresenta alguns exemplos dos desdobramentos das características classificadas como pós-modernas na música massiva/popular; a terceira discute algumas características do funk carioca como gênero musical e como cena cultural, inserindo-o no contexto político-econômico do Rio de Janeiro contemporâneo.

Se identifican varias areas de investigacion que pueden ser desarrolladas, utilizando las tecnologias nucleares, como por ejemplo en la reproduccion, nutricion, diagnostico y control de enfermedades, monitoreo ambiental y certificacion de la calidad de productos. En lo concerniente a nuestra acuicultura, se requieren investigaciones que ameritan el uso de estas tecnicas. Por ejemplo: 1) Produccion de agentes inductores autoctonos, mediante radioinmunoensayos (RIA) para determinar la actividad de las gonadotropinas provenientes de las hipofisis de los peces cultivados con la finalidad de recolectar las glandulas en el momento optimo, desencadenantes de la maduracion final y desove en especies autoctonas. 2) Mejoramiento genetico de especies cultivadas a traves del conocimiento de la carga genetica de diferentes lineas y razas encontradas en el medio natural y lograr su mantenimiento para resolver los problemas de endogamia, tanto en especies autoctonas como exoticas, con el uso de tecnicas de marcaje del ADE, RFLA y tecnicas de microsatelites. 3) Estudios nutricionales y de alimentacion de las especies sometidas a cultivo comercial, especialmente sobre el efecto de las aflatoxinas sobre los insumos o la racion, sustancias que influyen negativamente en la nutricion acuicola. En este caso se usan inmunoensayos competitivos de enzimas ligadas (ELISA) y radioinmunoensayos. 4) Diagnostico de enfermedades, mediante el kit ELISA, especificamente de las enfermedades mas comunes

    Directory of Open Access Journals (Sweden)

    CARLOS MOYA VALGAÑÓN

    1979-01-01

    Full Text Available T. Hobbes inventó el concepto moderno de estado y el discurso político racional. En Leviatán se equipara razón con gobierno. Se examina la historia occidental que precedió la redacción de Leviatán, comenzando con la cristianización progresiva de los reinos bárbaros. Fue la noción secularizada de razón, en contraposición al reinado de Dios sobre el mundo, la que proporcionó a la burguesía el fundamento epistemológico necesario para su ascensión social. La monarquía absoluta se convirtió en la primera forma del estado moderno. El desarrollo de la imprenta fue el instrumento tecnológico-industrial de la moderna revolución burguesa en la cristiandad occidental. La Reforma Protestante surgió de la nueva libertad para leer libros otrora prohibidos, constituyendo el primer ímpetu para el crecimiento industrial y el desarrollo de la empresa. Así, las revelaciones de la Santa Escritura dieron paso a la investigación científica y a la ciencia moderna.

    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

Este texto tem por objetivo cercar determinados “usos do primitivismo” na arquitetura sul-americana, que coincidem com a presença de materiais naturais, como a pedra e o barro, e de técnicas construtivas pré-industriais. Embora essa presença possa ser discutida apenas nos termos de uma relação com o “vernáculo”, adota-se propositalmente a noção de “primitivismo”, por exibir um impasse (de certa forma indiferente ao vernáculo de uma ligação intelectual, e não natural, com a tradição.

El mantenimiento preventivo se basa en la revision periodica de los equipos, mediante listas de inspeccion, donde la idea es detectar problemas que provoquen posibles fallas y realizar la reparacion o ajusted necesarios para evitarlo. Sin embargo enfrenta a la posibilidad de que el equipo este en perfecto estado y al estar en revision, tenga retrasos y problemas de arranque posteriores. El mantenimiento predictivo se basa en tecnicas que permiten la deteccion e identificacion de fallas incipientes en los equipos. Las tecnicas recomendadas en esta tesis son: Analisis de vibraciones; Evaluacion no destructivas e Inspeccion boroscopica. La estructura de la tesis consta de los capitulos siguientes: El capitulo uno describe la importancia de los programas y estrategias del mantenimiento, sus ventajas y desventajas al aplicarlas en las plantas de proceso continuo.

    Full Text Available A medicina moderna tem realizado muitas coisas nos campos de doenças infecciosas e de emergências para assistir a cura. Na maior parte dos outros campos, ela visa, sobretudo, ao controle, que é outro nome para o tratamento paliativo. A farmacologia, na qual se inclui a psicofarmacologia, é igualmente dirigida ao controle e ao alívio. Está na hora de profissionais da área e pesquisadores voltarem-se decisivamente para a prevenção e para a cura. Ademais, o outro grande desafio da medicina moderna é a longevidade aliada ao bem-estar. Avanços em vacinas contra hipertensão, diabetes, câncer etc. merecem atenção, bem como o papel da meditação, yoga, espiritualidade etc. na prevenção de doenças em vários níveis. Pesquisas sobre longevidade, mudanças no estilo de vida e centenários saudáveis merecem um exame especialmente minucioso na busca dos fatores que contribuem para a longevidade com bem-estar. Um olhar de perto para a medicina complementar e alternativa é necessário para encontrar modelos apropriados que esta possa vir a ter, à parte seus grandes discursos ou sua hostilidade para com o cuidado médico tradicional. A medicina é uma manifestação do Eros humano, e não deve tornar-se instrumento de seu Tanatos. Ela deve realizar seu verdadeiro potencial, de forma que Eros prevaleça, e Tanatos prevaleça apenas finalmente, não prematuramente.

In order to minimize the matrix effect, a model for correcting LIBS data by taking into account the plasma temperature experimentally determined both in the unknown and in the standard sample was introduced. Preliminary results showed a considerable improvement in the correlation coefficients for corrected LIBS data. Once the model validity is proven for different elements used in the plasma temperature determination, which is possible once known all the parameters of Boltzmann equation for experimental intensity spectral line, it is quite general and can be applied on all the samples and for all the elements. [Italian] Il LIBS (Laser induced breakdown spectroscopy) e' una tecnica spettroscopica sperimentale che trova applicazione nell'analisi di campioni di interesse ambientale, quali suoli e rocce, ed industriali, come leghe metalliche. In questo rapporto sono presentati i risultati dell'applicazione della tecnica a campioni eterogenei di suoli certificati dal Joint Research Centre di Ispra (Varese) per la valutazione delle concentrazioni di metalli pesanti di interesse agronomico (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn). Nella tecnica LIBS, un impulso laser d'alta potenza e' focalizzato sul campione in modo da provocare sulla superficie dello stesso un piccolo volume di plasma. Le emissioni delle singole specie atomiche sono raccolte da fibra ottica e analizzate da un monocromatore e da un analizzatore ottico (iCCD). Il riconoscimento e l'assegnazione delle emissioni spettrali corrispondenti ai singoli elementi atomici permette di riconoscere la

    Full Text Available Molti studi ormai hanno messo in evidenza la persistenza del fenomeno della schiavitù in epoca moderna sull’una e l’altra sponda del mar Mediterraneo, frutto di azioni di pirateria o di corsa che alimentavano un fiorente mercato. Il saggio analizza la presenza di schiavi cosiddetti ‘turchi’ a Firenze a partire dal XVII secolo fino a metà del XVIII, sulla base degli attestati di battesimo. Sebbene la natura della fonte impedisca una ricostruzione completa del quadro, permette però alcune interessanti osservazioni sui luoghi di origine degli schiavi, la loro età al momento del battesimo, e l’identità assunta dopo la cerimonia religiosa: particolarmente significativo il rinvenimento dei matrimoni tra alcuni neofiti e cristiani dalla nascita, che attesta la possibilità che si apriva ai primi, attraverso la conversione, di un pieno inserimento nella società cristiana.

    Full Text Available Este texto, que indaga sobre la producción crítica de Mário Pedrosa en torno a la arquitectura moderna brasileña, toma en consideración tres núcleos de análisis: el diferencial brasileño en relación con las propuestas del estilo moderno y las pervivencias de la tradición nativa y barroca, la conceptualización de Brasilia y las críticas y contradicciones vinculadas a la representación simbólica del poder estatal. Este trabajo sostiene que Pedrosa —entendiendo Latinoamérica como el espacio de relocalización del poder transformador de las vanguardias— invistió al desarrollo de la arquitectura moderna en Brasil como un fenómeno capaz de reactivar la utopía de un arte total.

La producción arquitectónica lograda en el período, en el presente de valor patrimonial, no cuenta con acciones gubernamentales ni legislación de protección. Esto se debe a dos razones concurrentes: La primera, desde el imaginario social el recorte temporal de lo patrimonial finaliza con la arquitectura de los años ’20 del siglo pasado. La segunda razón, la estética y la vigencia funcional de estas obras impiden poner la distancia crítica que requiere toda mirada histórica, aún más desde lo cultural. Vamos a revisar algunos autores a partir de sus trayectorias y su producción arquitectónica, con el objetivo de descubrir las singularidades de la producción local, haciendo aportes para la valoración de estos bienes y por ende para su patrimonialización.

La rápida pérdida de la biodiversidad y recursos naturales del Perú justifican la urgencia de apoyar aquellas investigaciones que ayuden a identificar, describir y caracterizar a la biodiversidad en la brevedad posible, para que se puedan tomar las debidas medidas de conservación y mitigación. Enfatizamos la importancia del uso de técnicas modernas dentro del modelo de estudio de la taxonomía integradora, incluyendo el estudio de los procesos evolutivos asociados a áreas con mayor diversidad y endemismo y los efectos del cambio climático sobre la biodiversidad peruana. Asimismo, es esencial que las entidades gubernamentales encargadas de evaluar los planes, solicitudes y requisitos asociados a las investigaciones de la biodiversidad del Perú reconozcan y apoyen el enfoque de la taxonomía integradora. El uso de técnicas modernas dentro del modelo de la taxonomía integradora, junto a procedimientos administrativos eficientes, puede convertirse en la mejor herramienta para proteger la biodiversidad peruana.

  17. Da Revolução: Arendt, uma moderna?

    2013-12-01

    Full Text Available Em Da Revolução, Arendt aponta para o vigor da política que renasce por meio das iniciativas revolucionárias. Por outro lado, é preciso atentar para o fato de que várias outras características presentes em Da Revolução apontam para aspectos críticos e negativos da modernidade que estão presentes dentro do âmago das próprias revoluções. O objetivo deste texto consiste em analisar os elementos modernos presentes nas revoluções que são admirados por Arendt, bem como os retornos que ela faz à antiguidade, de modo que seja possível contrapô-los e mostrar que, apesar de a autora louvar os feitos modernos das revoluções, o faz tendo Atenas e Roma como referências, já que a forma de participação dos conselhos provenientes das revoluções lembra, em grande escala, a polis grega, e a liberdade pública exaltada pelas revoluções (neste caso, a americana corresponde à liberdade dos antigos, da mesma maneira como o ato de fundação da república americana lembra com grande vigor a fundação da "cidade eterna". O objetivo, longe de enquadrar Arendt em alguma das categorias que seus comentadores já fizeram, está em perceber a relevância de não negar a importância que os antigos legaram para as considerações "modernas" de Arendt, assim como voltar os olhares para essa autora como alguém que realmente pensou seu tempo tendo os antigos como alguns parâmetros, mas não considerando isso de forma inteiramente negativa. Em outras palavras, trata-se de tentar assumir esse caráter presente na obra de Arendt, sem que ele seja tomado como um defeito.

    En pasadas publicaciones me he referido a la necesidad de revisar los planes de estudio y de reorientar la precaria condición de la educación médica colombiana, tan seriamente afectada, entre otros factores, por la crisis del sistema hospitalario público, sistema que ha sido el eje de la educación tanto de pregrado como de postgrado, y por las recientes disposiciones legales que han reformado los sistemas de salud y de seguridad social en Colombia (Patiño 1991,1992a,b,1993a,b,1998.

    Hace diez años Jiménez Arango se refería a los escenarios educativos en los servicios de salud y en los hospitales públicos, de tan mala calidad por su extrema pobreza y atraso tecnológico, que no constituían un ambiente favorable para una sólida formación en las ciencias clínicas. Hoy, en medio de la profunda crisis que afecta al sector hospitalario y al sector de la salud en general, la situación no ha mejorado y, por el contrario, aparece aún más deteriorada.

    En cuanto a los planes de estudios de las facultades de medicina, he planteado que un curriculum adecuado debe partir de la premisa de que el enorme volumen de conocimiento biomédico actual no puede ser transmitido en su totalidad al estudiante y que, forzosamente, se debe aceptar la imposibilidad de formar un médico que “sepa de todo”, mediante un curriculum único y rígido. Más bien deben identificarse los campos de acción que son previsibles en el ejercicio futuro de la medicina, y diseñar planes de estudio flexibles, diversificados y versátiles destinados a capacitar a los médicos para las diferentes áreas de la actividad profesional a través de programas que ofrezcan áreas de concentración o de “especialización” en el pregrado. Entre ellas, la principal sería la de la medicina familiar, que es la versión moderna de la medicina general (Patiño 1991, 1992a,b,1993ab.

Fundamentada nos conceitos de sedução, fascínio e servidão voluntária e trabalhando na instância mítica, esta pesquisa apresenta uma nova leitura do imaginário moderno e do discurso organizacional. A metodologia empregada foi de pesquisa qualitativa por meio de entrevistas semi-estruturadas com executivos de duas empresas modernas, líderes em suas organizações, que foram submetidas à categorização e à análise de discurso. Como resultado, foram apresentadas as descrições das relações dos executivos com os seus discursos organizacionais por meio de três categorias: submissão à vontade do dono, os preciosos recursos humanos e a supervalorização dos próprios predicados. Algumas das conclusões obtidas revelam que o executivo contribui para a construção do discurso organizacional, sujeitando-se de forma voluntária, simplesmente porque é favorável; assim como, pela mesma razão, contribui efetivamente para a adesão dos seus empregados, que ocorre por habitualidade, pelo comprometimento e pelo sonho do sucesso.ABSTRACTThis article describes the relationship between the executive and the organizational discourse of the modern company as it presents itself: how can the executive interfere with its creation, and the executive’s degree of acceptance and contribution in disseminating the organizational discourse amongst employees. Based on concepts of seduction, fascination, submission, and voluntary servitude and working in the mythical instance, this research presents a new reading of modern imaginary and organizational discourse.

    Full Text Available Regarding school curricula as social constructions, in this paper we analyze the building up of a tradition, which goes back to the 1960s, related to the introduction of Algebra in elementary school. This tradition is presented as an inheritance of the modern mathematics movement and it is argued that the analysis of curricular innovation processes should not take into account only their proclaimed purposes, but should consider broader effects related to the breakdown of older traditions. Keywords: History of Mathematics Education. Curriculum. Modern Mathematics. Teaching of Algebra.Na linha dos estudos que investigam os currículos escolares como construções sociais, este artigo examina a constituição de uma tradição relativa à iniciação em Álgebra na escola, cuja origem remonta aos anos 1960. Ao apresentar essa tradição como uma herança do movimento da matemática moderna, argumenta que os processos de inovação curricular não devem ser analisados apenas no confronto com suas intenções anunciadas, mas pelos efeitos mais amplos que produzem de desconstituição das tradições mais antigas. Palavras-chave: História da Educação Matemática. Currículo. Matemática Moderna. Ensino de Álgebra.

    Full Text Available Partiendo de una variedad de materiales textuales, el trabajo propone analizar los discursos de bailarinas y coreógrafas de danza moderna, así como su participación en la escena artística argentina durante las décadas de 1940 y 1950. El estudio de las moralidades vinculadas a verbalizaciones sobre el cuerpo en movimiento y el cuerpo en escena en las narrativas de “las pioneras”, nos informa sobre la emergencia de modelos de feminidad alternativos al de la bailarina clásica y la mujer tradicional occidental. Se busca abordar antropológicamente el estudio de estos procesos, explorando los modos en que las personas construyen sus elecciones en determinados contextos y configuraciones de ideas, sentimientos y creencias.

    Full Text Available La legislación de la Edad Moderna, como parte del discurso dominante, situó a las mujeres en una posición de inferioridad con respecto a los hombres. Esta discriminación se manifestó incluso en las normativas impuestas al cuerpo femenino. Aquí se analizan dos aspectos de esas normativas: el referido a la necesidad de cubrir el cuerpo de una determinada manera y el que concierne a la virginidad, cuya exigencia es consecuencia del control de la sexualidad femenina por parte del hombre.Law in Early Modern Times, as a part of the the prevailing discourse, put women in a position of inferiority in relation to men. This discrimination became apparent even in the rules imposed on women's body. The article analyses two aspects of these rules: the exigence for women to cover their body in a concrete way and the exigence of virginity, as a consequence of men's control of feminine sexuality

    Full Text Available Resumen: Se estudian los principales problemas que presenta la concepción moderna de libertad frente a la naturaleza. Primero, surge el problema de la liberación respecto del mundo objetivo, la cual trae aparejado la destrucción del entorno y el cuestionamiento de la viabilidad de la especie. Segundo, se presenta el problema de la complejizacion de lo social, frente al que sucumbe, en gran medida, el tema de la liberación política. Se concluye con la búsqueda de algunas alternativas ante estos dilemas. Abstract The article analyzes the problems posed by the modern conception of freedom before nature. The first to arise is the problem posed by the modern conception of freedom before nature. The first to arise is the problem of the emancipation from the objective world which brings along the destruction of the environment and the questioning about the viability of the species. The second problem is the complex character of the social life before whom succumbs, largely the issue of political emancipation. The article concludes which the search of some alternatives to these dilemmas.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Recentemente, o uso de chás medicinais - infusões, decoctos, tisanas, tinturas - ou medicamentos de origem vegetal vem sendo retomado de maneira sistemática e crescente na profilaxia e tratamento das doenças, ao lado da terapêutica convencional, na maioria dos países ocidentais. A presente revisão objetiva analisar as principais plantas que serviram como base de progresso para a moderna terapêutica anestesiológica através de sua utilização como modelos moleculares para síntese orgânica na moderna química fina de ponta, bem como fornecer mais embasamento sobre benefícios, potenciais efeitos adversos, interações e risco de efeitos colaterais que possam afetar o ato anestésico no paciente cirúrgico usuário habitual de fitoterapia. CONTEÚDO: Considerações anestesiológicas selecionadas são discutidas focalizando uma pequena revisão sobre ervas medicinais mais populares que foram essenciais no desenvolvimento de uma farmacologia anestesiológica e, ainda, as potenciais interações de plantas medicinais usadas por pacientes para tratar suas doenças ou controlar seus sintomas com drogas sintéticas usadas na anestesia. CONCLUSÕES: Enquanto a Medicina especializada fascina-se cada vez mais com a tecnologia avançada de novos fármacos e de fantásticos monitores, cresce em vários países o número de pacientes que desejam uma abordagem mais holística com rejeição dos modernos métodos de tratamento, optando por chás, meditações, dietas vegetarianas, anti-oxidantes, entre outros. Cabe ao anestesiologista avaliar quanto o conhecimento de farmacognosia e de farmacobotânica pode ajudá-lo na prática anestésica e, principalmente, na segurança de seu paciente.JUSTIFICATIVA Y OBJETIVOS: Recientemente, el uso de tés medicinales - infusiones, decocciones, tisanas, tinturas - o medicamentos de origen vegetal viene siendo retomado de manera sistemática y creciente en la profilaxis y tratamiento

    The coatings applied by thermal projection have an important number of applications in different industries (chemical, oil, electric, nuclear, etc.). The main purpose of the protection by means of coatings is to alter the surface characteristics of a component so as to resist corrosive environments, abrasion and erosion, among others. The coatings can be applied by different methods, but due to the fact that its characteristics appreciably differ from the base metal, it is important the knowledge of its properties when a coating is selected for a specific use. In this article the characteristics of the applied coatings by thermal projection, the factors that affect its performance and the principal application techniques, are described.

  14. RETRATANDO SUEÑOS. FOTOGRAFÍAS DE MAQUETAS DE ARQUITECTURA MODERNA EN ESPAÑA / Portraying dreams. Photographs of Modern Architecture models in Spain

    Directory of Open Access Journals (Sweden)

    Iñaki Bergera Serrano

    2016-11-01

    Full Text Available RESUMEN Referirse a la fotografía de maquetas implica enfrentarse a un desatendido subgénero fotográfico. Si la fotografía como disciplina, en relación con la arquitectura, no ha despertado hasta tiempos recientes la atención historiográfica y teórica que merece, cuando se trata de fotografía de maquetas, la genérica condición instrumental de esta la confina a los márgenes del discurso de la representación, alejada de las narrativas canónicas tanto de la arquitectura como de la fotografía. Rescatar y plantear un primer y explícito análisis, en el contexto de la arquitectura moderna en España, de este amplio y particular legado fotográfico —hasta la fecha nunca atendido y valorado como tal— plantea el reto de ver en qué medida es posible trazar los mimbres de un discurso reivindicativo que haga justicia con la fortuna crítica de ambas, fotografías y maquetas, como canales de visualización de la arquitectura moderna mediante un discurso autónomo que trasciende su mera naturaleza documental. Subsidiariamente esta revisión apunta a una posible historia paralela de la arquitectura moderna española a través de sus maquetas y refiere por tanto no ya a la historia transitada sino a aquella otra —en aletargada miniatura— que podría haber sido. SUMMARY To consider the photography of architectural models is to confront one of its most neglected sub-genres. The discipline of the photography of architecture has not captured until recently the attention of scholars and historians that it deserves. Its generic functionality seems to confine it to the margins of any discourse on representation, far removed from the canonical narratives of both architecture and photography. To reevaluate and make the first explicit analysis of such an extensive and unique photographic legacy in the context of modern architecture in Spain — up to now underrated and ignored — poses the challenge of seeing how far it is possible to sketch out

  16. La definición de las trayectorias literarias en dos escritoras chilenas modernas: María Flora Yáñez y Marta Brunet

    Directory of Open Access Journals (Sweden)

    Natalia Cisterna

    2014-05-01

    Full Text Available El artículo se propone analizar la configuración de la trayectoria literaria en dos escritoras chilenas modernas, María Flora Yáñez y Marta Brunet, considerando que sus distintas inserciones en el campo cultural de su época están determinadas por sus respectivos orígenes sociales y las normas de género sexual. María Flora Yáñez y Marta Brunet son parte de una generación de autoras profesionales que entienden su ejercicio escritural como una actividad pública, reconociendo en ella características propias, distintas a otras prácticas discursivas y que debe ser perfeccionada a través del tiempo a partir de una labor permanente de lectura, escritura y divulgación de sus obras. Para las mujeres, sin embargo, la profesionalización se experimentó con dificultades producto de la persistencia de discursos que limitaban su ingreso en las esferas públicas y, por tanto, culturales. El silencio letrado al que históricamente ha sido sometido el género femenino impulsó el surgimiento de voces críticas que leían con desconfianza o rechazo el trabajo de las autoras modernas, lo que las obligó a definir trayectorias literarias a partir de distintas estrategias que posibilitarán su reconocimiento en los campos culturales. Estas estrategias dieron lugar a un campo profesional femenino heterogéneo, en donde el habitus de clase social y las normas de género jugaron un papel fundamental al configurar sus particulares relaciones con el campo cultural y, en definitiva, sus trayectorias.

    Directory of Open Access Journals (Sweden)

    Viviane da Silva Araujo

    2015-03-01

    Full Text Available No Rio de Janeiro, os primeiros anos do século XX foram marcados por uma série de reformas urbanas vinculadas aos objetivos das classes dirigentes de construir uma capital compatível com o nível de civilidade e cosmopolitismo que permitisse inserir não apenas a cidade, como também o país que ela era incumbida de representar, no rol do mundo moderno. Entretanto, o crescimento urbano não acarretou apenas efeitos entendidos como progressos, mas gerou uma cidade ainda mais complexa, heterogênea e conflituosa, características que cada vez mais definiriam a vida na cidade moderna. Este artigo analisa as fotografias de Augusto Malta desde a destruição dos cortiços até o surgimento das primeiras favelas no Rio de Janeiro, com o objetivo de refletir sobre o embate entre as expectativas de construção de um futuro moderno e civilizado e a apreensão de uma realidade multifacetada que parecia cada vez mais imprevisível.

    2017-03-01

    Full Text Available DOI: 10.12957/periferia.2016.24747O artigo tem como objetivo mostrar ao leitor uma estrutura de estudos, que levaram a uma teoria universal e estruturalista do desenvolvimento moral das pessoas e da sociedade, e ao mesmo tempo demonstrar a que ponto chegamos. São apresentados estudos que contemplam desde a formação de uma moral universal e estruturalista, com o pensamento do filósofo Immanuel Kant e sua influência para a teoria de Piaget e Kholberg, no desenvolvimento moral de uma pessoa dividida em seus específicos estágios, até os estudos atuais que mostram as conclusões de Bauman sobre a sociedade pós-moderna e suas implicações no âmbito social e pessoal. As consequências de uma fragmentação social em vários aspectos são colocadas à mostra a fim de chamar a atenção do leitor para ter consciência e percepção de sua existência. Um excesso de contradições é posto para o leitor confrontar com a pós-modernidade um quadro negativo de ações presentes, e levar à reflexão do que pode ser alcançado diante do que nós temos atualmente na nossa sociedade.

    1994-07-01

    In order to compare three radiographic techniques -pneumocolon, barium enema and double contrast- in the large intestine of the dog, three radiographic series in ventrodorsal and right lateral projections were taken. Six healthy adult dogs of both sexes with an approximate weight between 5 to 10 kg were used. Three enemas were administered 24, 12 and 2 hrs. before the series of radiographs were taken. Then dogs were anaesthetized with sodium tiopental (20 mg/kg iv) and the contrast media were introduced. Pneumocolon was carried out in the first series introducing air (20 cc/kg) in the large intestine through a Foley rectal catheter. Radiographs were taken in both projections, after 5 and 15min. respectively. Barium enema was performed in the second series introducing barium sulfate (18%) in the large intestine through a Foley rectal catheter (25 cc/kg); 5 and 15 min. later, the radiographs were taken. In the third series -double contrast- the barium sulfate, which was obtained from each dog using a catheter, was substituted by a volume of air equal to that obtained from the contrast medium. Later the radiographs were taken in both projections. The radiographic plates of each series were analized comparing the characteristics of: radiographic density, outline and volume. With the pneumocolon barium enema and double contrast, the radiographic density was, in most cases, low, high and inter-mediate respectively. The radiographic outline was, in most cases, regular for the three techniques. Thee radiographic volume was similar in all of the series. From the results obtained, it is concluded that double contrast best outlines the intestinal mucosa and more information can be obtained from it [Spanish] Con la finalidad de comparar tres tecnicas radiograficas del intestino grueso del perro -neumocolon, enema baritado y doble contraste-, se tomaron tres series radiograficas en proyeccion ventrodorsal y lateral derecha en 6 perros adultos, de 5 a 10 kg de peso, que

    Directory of Open Access Journals (Sweden)

    Juliana Cardoso Nery

    2016-12-01

    Full Text Available Este artículo se basa en resultados de la investigación que analizó un corpus de 225 ediciones de las revistas A CASA y ARQUITETURA E URBANISMO, publicado entre 1923 y 1942, cuyo fin consistió en identificar a través de los textos e imáge- nes divulgados las transformaciones de los significados y formas de expresión de “lo moderno”. Se busca, de este modo, entender cómo este término que albergaba una gama diversificada de expresiones se convirtió en una línea hegemó- nica, bastante definida en la arquitectura brasileña, que incluso admitió la denominación de Movimiento Moderno para ser identificado. El “estylo” moderno aparece en las revistas brasileñas a partir de la Exposición de Artes Industriales y Decorativas Modernas de 1925 en París, donde se presentaron diversas manifestaciones arquitectónicas que fueron, por cierto, identificadas indistintamente como “modernas” en las revistas analizadas. Estas variadas expresiones de lo moder- no, ignoradas por la mayoría de las narrativas históricas, fueron precisamente las responsables de conquistar y fertilizar -en gran parte debido a publicaciones de revistas especializadas- un campo árido en el cual florecerían luego las excep- cionales obras de la arquitectura moderna brasileña de matriz corbusiana, celebradas a nivel nacional e internacional.

    Full Text Available RESUMEN: La historia rural de la España oriental durante la Edad Moderna: un estado de la cuestión. En este artículo se traza un estado de la cuestión de la historia agraria de los territorios de la antigua Corona de Aragón y la región murciana durante la Edad Moderna. Se analiza en primer lugar la evolución cronológica de ciertas variables fundamentales, como son la población y los indicadores de producción agraria, repasándose las consecuencias de ciertos acontecimientos considerados puntos de ruptura fundamentales, como la sentencia arbitral de Guadalupe o la expulsión de los moriscos. Seguidamente se estudian los aspectos esenciales de la historia agraria propiamente dicha, como son los cultivos, la ganadería, el bosque, el regadío y las técnicas agrarias. Finalmente se dedica un tercer y último apartado a la historia social agraria, en el que se trata el señorío, la propiedad, las formas de cesión y explotación de la tierra, los procesos de diferenciación social, las normas hereditarias y la confl ictividad social.ABSTRACT: The Rural History of Oriental Spain during the Early Modern Period: a State of the Art.

    achievements in technical cooperation in each of the regions in 2007, describing regional emphases and responses to national priorities. As the Millennium Development Goals remain a key area of focus, the report demonstrates how the IAEA is making a contribution to global efforts to fight poverty, hunger and disease, as well as to support environmental sustainability and the health of mothers and children. Health in Asia was addressed in 2007, for example, through regional projects to train new medical staff, while in Europe, radiotherapy services were being upgraded in the Balkans. In Africa, projects on better animal health and improved crop productivity contributed to the fight against hunger, and in Latin America, activities in food fortification and the determination of vitamin deficiency helped to improve the health of mothers and children. Ensuring sustainable socioeconomic development in the future will depend on a reliable energy supply. Among the energy-related technical cooperation projects in Africa in 2007, support to energy planning helped to train national energy planning teams in Burkina Faso, Chad, Cote d'Ivoire, Mauritania and Niger. Assistance was also being provided to several African countries to help with the different stages of planning a nuclear power programme. In Asia and the Pacific, RCA Member States received support in the application of Agency-developed analytical tools for energy planning. In Latin America, energy security is seen as a priority issue. In 2007, the Agency provided assistance to the conversion of Europe's older research reactors from high to low enriched uranium. In Asia and the Pacific, the Agency provided advice on the development of nuclear power, based on the latest Agency guidelines and the document 'Milestones in the Development of a National Infrastructure for Nuclear Power'.

  2. From city’s station to station city. An integrative spatial approach to the (redevelopment of station areas

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Since its origin, the railway station has had a complicated relationship with the city, demanding periodical updates, particularly regarding spatial issues. With the aim of improving the liveability of station areas, current redevelopment projects are reconceptualising them as balanced transport ‘nodes’ and ‘places’ in the city. However, the proposed spatial solutions do not fully support the sought after economic, social and environmental performances. These intentions continue to be predominantly bounded with the (abstract planological level, not finding appropriate translation at the (concrete spatial design level. Further, the interdisciplinary nature of the highly complex planning and design processes of station areas, which should contribute to enhance the performance of their spaces, reinforces constraints and relegates architecture to a marginal role in this quest. It is thus necessary to understand how architecture can contribute to the improvement of the spatial performance of contemporary stations areas, supporting their current reconceptualization. To gain this understanding, the research explored the factors which influence the spatial definition and performance of European High Speed Train station areas, using “design research” and “research by design”. Via a theoretical integrative framework, synthesized from knowledge developed by architecture and other sciences, case studies of ‘through’ stations were analysed and compared. Six cases, encapsulating the most recurrent relative positions of the railway (infrastructure and the station building towards the(ir direct built environment, were chosen out of a large sample. For each category (cases with railway tracks at (a ground level, (b elevated level and (c underground level, two cases, featuring an adapted station building and a newly built one, were studied. Their physical and functional characteristics were mapped at several scales and moments (in history, as

    Full Text Available Este texto estudia la constitución de mujeres modernas durante el siglo XIX en Colombia, y ahonda en los cambios que en los años de 1930 y 1940 inflamaron el debate sobre este tópico, justamente cuando aumentaron las reivindicaciones de igualdad entre los sexos, se agudizaron las luchas por la emancipación femenina y diversas transformaciones sociales hicieron inminente revisar la doctrina sobre la educación de las mujeres. Al margen de las diferencias expresadas respecto a la conveniencia de que las mujeres adquirieran el derecho al voto y ampliaran su educación escolar y su participación en la vida pública, tanto promotores como detractores de estas transformaciones coincidieron en proteger el núcleo básico de la educación de la mujer, constituido en el siglo XIX en sus expresiones de ama de casa, madre y esposa. Durante estos años se sumó la belleza al conjunto de deberes de la feminidad, que de don natural pasó a ser asequible mediante el consumo y el esfuerzo acumulados en el capital corporal femenino.

Sujetas a una fuerte presión ideológica, no son los discursos, sino sus contradicciones lo que más repercute en su vida diaria. Realidad que no impide que, en la Edad Moderna, se produzcan cambios positivos y que la práctica social les fuera abriendo esferas de actuación que la ley no contemplaba. Por ello, así como resulta imposible abordar la historia de las mujeres sin. hacer referencia a la evolución de la familia de un modelo jerárquico y patriarcal, a otro, también patriarcal, pero de relaciones asentadas sobre el afecto, tampoco se puede entender el porqué de esta transformación sin integrar ni manejar las categorías analíticas adecuadas.ABSTRACT: Even though gender and family are complementary views, both terms are not used at the same time, and the result is that cultural conditions that makes particular women's situation in the family are often omitted. Under a heavy ideological pressure, the contradictions were what most strongly influenced a woman everyday's life. -This fact does not mean that there were no positive changes in early modern age. Some spheres of activity were opened to women aside from the prevailing legal principles. That is to say that Women History can not be approached without considering the evolution in family as a institution, which from patriarchal and hierarchical patterns turned into a patriarchal one in which relationship is based on affection. This change can not be understood without and using suitable analitic categories.

    In this work, a study was conducted of the flooding and dehydration processes of a PEM fuel cell using the EIS technique. The experiments were conducted in a 50 cm{sup 2} cell. The gradual flooding of the system was induced by operating the cell at a potential of 0.3 V and maintaining the gas outlet closed (that is, stoichiometry of 1 for the anode (H{sub 2}) and the cathode (O{sub 2})) to enable the water produced by the reaction to accumulate inside. The gradual dehydration was induced by operating the cell at a potential of 0.3V and establishing a oxidized gas flow at a stoichiometry of 4. EIS tests were applied throughout both processes. The results showed that the EIS technique is highly sensitive for the analysis of the different degrees of the flooding processes by monitoring variations in the imaginary components of total impedance (Z{sup )} or the phase angle ({theta}). For low degrees of flooding, the technique had good sensitivity, between 1 and 6 Hz, while at high degrees of flooding the technique's greatest sensitivity was limited to a range between 1 and 2 Hz. In the case of the dehydration process of the system, the results showed that this type of process can be analyzed for variations in the value of the real component (Z{sup '}) as well as for the imaginary component of total impedance and variations in the phase angle. The analysis of dehydration with Z{sup '} was possible at a rather wide range, from 100 to 1000 Hz; with Z{sup }or {theta} it was only possible at a range of 20 to 200 Hz.

En este sentido, busca una discusión de dos vías que trae a colación varias contradicciones presentes en la invocación de esta ciencia en los aspectos modernos. Primero, el artículo enfatiza las dificultades de unir clínica y ciencia; adicionalmente sugiere que las visiones de la hipnosis pueden ser aplicables también, de forma general, a la psicología clínica, que a su vez supone que los pensamientos evocados por la hipnosis todavía tienen una pertinencia considerable para esta asociación, clínica y ciencia. Segundo, el artículo también postula que las instituciones involucradas en la formación de la Psicología tuvieron un papel crucial en la determinación de una visión distorsionada no sólo de la hipnosis sino de lo que podría o no considerarse científico. Finalmente, el artículo propone que aunque el estudio de la hipnosis no muestra una gran cantidad de respuestas en el sentido moderno, todavía es pertinente al invocar preguntas importantes sobre la construcción de dicha ciencia. Algunas de estas preguntas están relacionadas con las deformaciones históricas hechas por los procesos institucionales y por el aspecto científico de la práctica clínica.

    Rogério Ferrer Koff

    2018-04-01

    Full Text Available O texto problematiza a noção moderna de humanidade, enquanto gênero universal, baseada em uma certa visão da natureza humana, em uma cultura de fundamentos e em uma profunda convicção na existência de uma essência universal do homem. A crise da noção de essência faz surgir a historicidade como a forma cabal do pensamento no século XIX, o que teria quebrado o caráter unívoco da palavra “ciência”. O pensamento do Século XX e do alvorecer do novo milênio nos parecem herdeiros desta crise. A relativização da ordem da verdade e a consequente ideia de um caráter provisório do conhecimento e da moral obteve abrigo no pensamento pós-moderno, caracterizado pela rejeição da tradição racionalista inaugurada no pensamento grego clássico e vigente até o Iluminismo. A experiência moderna e sua ênfase na universalidade do gênero humano passou a ser considerada positivista e etnocêntrica. No lugar de verdades absolutas, emergiram as categorias de heterogeneidade, diferença e relativismo.   PALAVRAS-CHAVE: Modernidade; Relativização; humanismo.     ABSTRACT The text problematizes the modern notion of humanity as a universal genre based on a certain vision of human nature, a culture of foundations and a deep conviction in the existence of a universal essence of man. The crisis of the notion of essence gives rise to historicity as the full form of thought in the nineteenth century, which would have broken the univocal character of the word "science." The thought of the twentieth century and the dawn of the new millennium seem to us inheritors of this crisis. The relativization of the order of truth and the consequent idea of ​​a provisional character of knowledge and morality gained shelter in postmodern thought, characterized by the rejection of the rationalist tradition inaugurated in classical Greek thought and in force up to the Enlightenment.

    This paper introduces the Japanese experiment module (JEM) in developing a space station. The JEM consists of systems of a pressurizing section, an exposure section, a pressurizing portion of a supply section, a manipulator and an exposure portion of the supply section. The pressurizing section circulates and controls air so that crews can perform experiments under pressurized environment. The exposure section is a part in which experiments are carried out under exposure environment. The supply section runs between a station and the ground, with required devices loaded on it. The manipulator performs attaching a payload for the exposure section and replaces experimental samples. The JEM undergoes a schedule of fabricating an engineering model, testing for a certification a prototype flight model, and putting the model on a flight. The pressurizing section, exposure section and manipulator are at the stage of system tests. Surveillance of the JEM and control of the experiments are carried out at the Tsukuba Space Center. The Center is composed of a space experiment building, a zero-gravity environment testing building, an astronaut training building, a space station operating building, and a space station testing building. 7 figs., 2 tabs.

    1998-12-01

    Full Text Available A geografia moderna nasceu com expressiva característica dualística, evidenciada pelo tratamento da natureza por um lado e, por outro, pelo da sociedade e de suas dinâmicas. Com o aprofundamento destes dois ramos no século XX e com o desenvolvimento do pensamento crítico dentro da ciência, através do qual ressaltou-se o caráter ideológico do pensamento científico, o dualismo geográfico foi alçado à condição de dicotomia. Dualidade e dicotomia da geografia tornaram-se então, sobretudo depois da década de cinquenta, temas de acirrados debates na academia e nas entidades de congregação de geógrafos. Este tipo de debate intensificou-se dentro da geografia brasileira a partir do final dos anos setenta, tendo promovido um considerável distanciamento entre geógrafos físicos e geógrafos humanos.

  20. Station Set Residual: Event Classification Using Historical Distribution of Observing Stations

    Science.gov (United States)

    Procopio, Mike; Lewis, Jennifer; Young, Chris

    2010-05-01

    Analysts working at the International Data Centre in support of treaty monitoring through the Comprehensive Nuclear-Test-Ban Treaty Organization spend a significant amount of time reviewing hypothesized seismic events produced by an automatic processing system. When reviewing these events to determine their legitimacy, analysts take a variety of approaches that rely heavily on training and past experience. One method used by analysts to gauge the validity of an event involves examining the set of stations involved in the detection of an event. In particular, leveraging past experience, an analyst can say that an event located in a certain part of the world is expected to be detected by Stations A, B, and C. Implicit in this statement is that such an event would usually not be detected by Stations X, Y, or Z. For some well understood parts of the world, the absence of one or more "expected" stations—or the presence of one or more "unexpected" stations—is correlated with a hypothesized event's legitimacy and to its survival to the event bulletin. The primary objective of this research is to formalize and quantify the difference between the observed set of stations detecting some hypothesized event, versus the expected set of stations historically associated with detecting similar nearby events close in magnitude. This Station Set Residual can be quantified in many ways, some of which are correlated with the analysts' determination of whether or not the event is valid. We propose that this Station Set Residual score can be used to screen out certain classes of "false" events produced by automatic processing with a high degree of confidence, reducing the analyst burden. Moreover, we propose that the visualization of the historically expected distribution of detecting stations can be immediately useful as an analyst aid during their review process.

    The weakness of small island electrical grids implies a handicap for the electrical generation with renewable energy sources. With the intention of maximizing the installation of photovoltaic generators in the Canary Islands, arises the need to develop a solar forecasting system that allows knowing in advance the amount of PV generated electricity that will be going into the grid, from the installed PV power plants installed in the island. The forecasting tools need to get feedback from real weather data in "real time" from remote weather stations. Nevertheless, the transference of this data to the calculation computer servers is very complicated with the old point to point telecommunication systems that, neither allow the transfer of data from several remote weather stations simultaneously nor high frequency of sampling of weather parameters due to slowness of the connection. This one project has developed a telecommunications infrastructure that allows sensorizadas remote stations, to send data of its sensors, once every minute and simultaneously, to the calculation server running the solar forecasting numerical models. For it, the Canary Islands Institute of Technology has added a sophisticated communications network to its 30 weather stations measuring irradiation at strategic sites, areas with high penetration of photovoltaic generation or that have potential to host in the future photovoltaic power plants connected to the grid. In each one of the stations, irradiance and temperature measurement instruments have been installed, over inclined silicon cell, global radiation on horizontal surface and room temperature. Mobile telephone devices have been installed and programmed in each one of the weather stations, which allow the transfer of their data taking advantage of the UMTS service offered by the local telephone operator. Every minute the computer server running the numerical weather forecasting models receives data inputs from 120 instruments distributed

  13. The Trencin water power station

    2005-01-01

    This leaflet describes the Trencin water power station. The Trencin water power station was built seven years after the Dubnica nad Vahom water power station started its operation and was the last stage of the first and the oldest derived cascade of water power stations on the Vah River. After completing water power stations at Ladce (1936), Ilava (1946) and Dubnica nad Vahom (1949) and before constructing the Trencin water power station, the whole second derived cascade of water power stations including water power stations at Kostolna, Nove Mesto nad Vahom and Horna Streda was built as soon as possible mainly because the need to get compensation for discontinued electricity supplies as well as energetic coal from the Czech Republic. Hereby, experiences from the construction of previous grades were used, mainly as far as the dimensioning was concerned, as the fi rst installed power stations had, in comparison with the growing requirements on the electricity supplies, very low absorption capacity - only 150 m 3 .s -1 . Thus the Trencin power station (original name was the Skalka power station) was already dimensioned for the same absorption capacity as the cascade located downstream the river, that is 180 m 3 .s -1 . That was related also to growing demands on electricity supplies during the peaks in the daily electric system load diagram, and thus to the transfer from continuous operation of the water power station to semi-peak or even peak performance. According to the standards of power station classification, the Trencin water power station is a medium size, low pressure, channel power station with two units equipped by Kaplan turbines and synchronous hydro-alternators. The water power station installed capacity is 16.1 MW in total and its designed annual production of electrical energy for medium water year is 85,000 MWh, while the average annual production during the last 30 years is 86,252 MWh. Installed unit has a four-blade Kaplan turbine with the diameter

    1986-01-01

    A wide variety of space station applications for tethers were reviewed. Many will affect the operation of the station itself while others are in the category of research or scientific platforms. One of the most expensive aspects of operating the space station will be the continuing shuttle traffic to transport logistic supplies and payloads to the space station. If a means can be found to use tethers to improve the efficiency of that transportation operation, it will increase the operating efficiency of the system and reduce the overall cost of the space station. The concept studied consists of using a tether to lower the shuttle from the space station. This results in a transfer of angular momentum and energy from the orbiter to the space station. The consequences of this transfer is studied and how beneficial use can be made of it.

    Full Text Available Las economías modernas que funcionan dentro de paisajes tradicionales van siendo un fenómeno creciente en muchas partes del mundo. El lugar, motivo del presente estudio, es Huixquilucan, México, un municipio complejo en el borde montañoso del Valle de México, que la ciudad de México ha comenzado a invadir. La apariencia general y la distribución del uso del suelo dentro del municipio dan todavía la impresión de que la población está dedicada al cultivo de maíz, actividad típica del México pre–industrial. Sin embargo, el análisis de la estructura de ocupación del municipio revela lo contrario: la población se dedica a actividades que no son agrícolas, particularmente tiene empleos en la ciudad de México. Esta situación se describe en este trabajo como un "paisaje de atraso" en el que la estructura de ocupación del campo no refleja ya el uso primario del suelo. En el análisis se plantean problemas fundamentales de persistencia, cambio y predicción.

Es innegable la relevancia de este relato al interior de su obra, así como su aporte al desarrollo del género narrativo. Sin embargo, el cuento de Poe puede ser considerado, a su vez, como una fuente de notable influencia en la redefinición del concepto de modernidad que Baudelaire plasmará en su obra "El pintor de la vida moderna". Al examinar el personaje anónimo de "El hombre de la multitud" y la singularidad del Sr. G, pintor que da fundamento a la crítica de la tradición pictórica de costumbres, quedará en evidencia como los principales argumentos de Baudelaire sobre el arte y las nuevas formas de habitar la ciudad moderna encuentran en el relato de Poe una significativa fuente de inspiración.The 19th century gave rise to new forms of metropolitan subjectivity with an exceptional treatment in EdgarAllan Poe's tale "TheMan of the Crowd". The relevance of this short story into his work is undeniable, as well as its contribution to the development of the narrative genre. However, Poe's story can be considered as a source of considerable influence in the redefinition of the concept of modernity, that Baudelaire will express in his work "The Painter of Modern Life". In examining the anonymous character of "The Man of the Crowd" and the singularity of Mr. G, the painter who gives substance to the criticism of the pictorial tradition of customs, it grows evident how Baudelaire's main arguments on art and the new ways of life in the modern city find in Poe's short story a significant source of inspiration

Relaciona los modelos de cambio arquitectónico y social con las formas en que los individuos describieron su experiencia y uso del espacio doméstico en los registros judiciales. Concluye que, si bien existía una tendencia a separar el trabajo y los espacios de vida de los sirvientes del resto de la familia, una casa moderna temprana no era aquella en la que los patrones sociales rígidos y estáticos estaban mapeados. Una serie de factores sociales lucharon por definir el carácter social de un espacio, una lucha que giró en torno a los conceptos de control y uso en lugar de separación o segregación según el estatus o el género. Los patrones espaciales fueron efímeros, no obstante, es posible ilustrar cómo algunos aspectos de las relaciones sociales de la familia se reflejaron y se reforzaron por la forma en que se organizó y utilizó el espacio doméstico.

  3. The Miksova water power station

    International Nuclear Information System (INIS)

    2005-01-01

    This leaflet describes the Miksova water power station. The Miksova water power station is part of the second derived cascade of hydro power stations on the river Vah. It was built at the end of a huge development in Slovak hydro-energy in the late 1950's and the beginning of the 1960's. It is the second water power station on this derived cascade, which is situated downstream the Hricov reservoir and water power station. At the power station, three turbine sets with vertical Kaplan turbines are installed with a total power output of 3 x 31.2 = 93.6 MW. With this power output the Miksova water power station (Miksova I) was the biggest water power station in the Slovak Republic until the construction of Pumping water power station Liptovska Mara. And it is still the biggest channel water power station on the Vah so far. It was put into operation during the period 1963 to 1965. There are three turbine sets with Kaplan turbines from CKD Blansko, with a synchronous hydro-alternator installed in the power station. Their installed capacity is 93.6 MW in total and the projected annual production of electrical energy is 207 GWh. The turbines are fi ve-bladed (on the Hricov and Povazska Bystrica water power stations they are four-bladed) and the impeller wheel has a diameter of 4800 mm. They are designed for extension of the head from 24.1 to 22.21 m and each of them has an absorption capacity of 134 m 3 .s -1 nd a nominal operating speed of 2.08 m 3 .s -1 , runaway speed 4.9 m 3 .s -1 . Each synchronous hydro-alternator has a maximum power output of 31.2 MW, a nominal voltage of 10.5 kV and power factor cos φ of 0.8. Power from the power station is led out through 110 kV switchgear. The water power station operates under automatic turbine mode of operation with remote indication and control from the Dispatch Centre at Vodne elektrarne, in Trencin. From start of operation until the end of 2003 all three turbine sets operated for a total of 450,500 running hours and the

    Propulsion system requirements to support Low Earth Orbit (LEO) manned space station development and evolution over a wide range of potential capabilities and for a variety of STS servicing and space station operating strategies are described. The term space station and the overall space station configuration refers, for the purpose of this report, to a group of potential LEO spacecraft that support the overall space station mission. The group consisted of the central space station at 28.5 deg or 90 deg inclinations, unmanned free-flying spacecraft that are both tethered and untethered, a short-range servicing vehicle, and a longer range servicing vehicle capable of GEO payload transfer. The time phasing for preferred propulsion technology approaches is also investigated, as well as the high-leverage, state-of-the-art advancements needed, and the qualitative and quantitative benefits of these advancements on STS/space station operations. The time frame of propulsion technologies applicable to this study is the early 1990's to approximately the year 2000.

  9. Single-Station Sigma for the Iranian Strong Motion Stations

    Science.gov (United States)

    Zafarani, H.; Soghrat, M. R.

    2017-11-01

    In development of ground motion prediction equations (GMPEs), the residuals are assumed to have a log-normal distribution with a zero mean and a standard deviation, designated as sigma. Sigma has significant effect on evaluation of seismic hazard for designing important infrastructures such as nuclear power plants and dams. Both aleatory and epistemic uncertainties are involved in the sigma parameter. However, ground-motion observations over long time periods are not available at specific sites and the GMPEs have been derived using observed data from multiple sites for a small number of well-recorded earthquakes. Therefore, sigma is dominantly related to the statistics of the spatial variability of ground motion instead of temporal variability at a single point (ergodic assumption). The main purpose of this study is to reduce the variability of the residuals so as to handle it as epistemic uncertainty. In this regard, it is tried to partially apply the non-ergodic assumption by removing repeatable site effects from total variability of six GMPEs driven from the local, Europe-Middle East and worldwide data. For this purpose, we used 1837 acceleration time histories from 374 shallow earthquakes with moment magnitudes ranging from M w 4.0 to 7.3 recorded at 370 stations with at least two recordings per station. According to estimated single-station sigma for the Iranian strong motion stations, the ratio of event-corrected single-station standard deviation ( Φ ss) to within-event standard deviation ( Φ) is about 0.75. In other words, removing the ergodic assumption on site response resulted in 25% reduction of the within-event standard deviation that reduced the total standard deviation by about 15%.

    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)

    1963-10-15

    Canada's Nuclear Power Demonstration station (NPD), initiated by the federal agency Atomic Energy of Canada Limited, is operated and staffed by the Hydro-Electric Power Commission of Ontario, a provincial public utility. Obtaining and training staff for the station was hampered by the fact that until recently most of Ontario's electricity requirements were supplied by the abundant hydro-electric resources of the province. Increasing use of thermal-electric energy since 1950 created an extreme shortage of staff experienced in the operation of thermal stations. To meet this situation, trained manpower for nuclear generating stations was developed by the following steps: (1) An initial group of professional engineers was selected from among persons with considerable experience in nuclear work, thermal stations and electrical operation; (2) Another group of highly experienced operators and maintainers was selected; (3) The selected groups were given a rigorous training programme involving operation of both nuclear and coal-fired stations, instruction from the designers of NPD and training in the classroom and on the job; and (4) A nuclear training centre was established to select and train additional staff, conduct formal examinations and be generally responsible for personnel quality standards. Independent examinations of personnel were conducted by the Atomic Energy Control Board, a separate federal regulatory agency. Five general categories of personnel are being developed: (1) Supervisors: professional engineers responsible for operation, maintenance and administrative supervision, rotated periodically to increase their versatility; (2) Operators: four levels of qualification depending on the requirements of the job; (3) Control maintainers: four levels of qualification, responsible for maintenance of all instruments, control equipment and electrical equipment; (4) Mechanical maintainers: various levels and combinations of skills (welding, machining, fitting, etc

    . Estos aspectos han provocado que dichos sistemas operen con margenes de seguridad mas limitados y que su estabilidad tenga que ser analizada de una manera confiable y precisa. Tomando en cuenta los aspectos arriba mencionados, a medida que los sistemas electricos han tenido que operar en condiciones mas forzadas para satisfacer la demanda de la carga, los problemas de estabilidad de voltaje se han presentado con mayor frecuencia provocando serios disturbios y en algunos casos, hasta apagones totales. Ante la ocurrencia de estos problemas, el analisis de establidad de voltaje ha cobrado cada vez mayor importancia en los estudios de las companias suministradoras de energia electrica provocando con esto que se destinen mayores recursos para la investigacion de este fenomeno con el proposito de comprenderlo y desarrollar tecnicas y herramientas que permitan estudiarlo de una manera mas completa. El analisis modal es una de las mas recientes tecnicas en estado estable la cual, desde su aparicion ha tenido un gran auge debido a la valios y rapida informacion que proporciona, ademas de su facilidad de implementacion y el poco esfuerzo computacional que requiere. En este trabajo se realiza la evaluacion de la estabilidad de voltaje d eun sistema electrico real aplicando de manera conjunta la tecnica de analisis modal con otras tecnicas convencionales como las curvas P-V y V-Q. Se ilustra tambien la manera en que la distinta informacion obtenida de estas tecnicas se complementa para lograr un estudio de estabilidad de voltaje mas completo y representativo. Ademas de analizar la estabilidad de voltaje para las condiciones normales de operacion (caso base), se evaluan tambien tres distintas alternativas de compensacion reactiva capacitiva con objeto de mejorar el margen o distancia a la inestabilidad de voltaje del sistema. Los resultado obtenidos con cada una de las opciones de compensacion son analizados y comparados entre si para finalmente proponer la alternativa que presente

    Dielectric spectroscopy is a measurement technique to characterize the interaction between electromagnetic energy and macroscopic samples as a function of frequency. It is based on the measurement of complex permittivity plus conductivity and it has shown to be very useful to provide information about internal structure of matter. It has some advantages over others like optical or chemical analysis: it is very fast, easy to implement, requires little or no preparation of the sample, it can be non-destructive and/or minimally intrusive. In this paper the development of a dielectric spectroscopy system for the microwave frequency range (50 MHz-20 GHz), using an open-ended coaxial probe as sensor, is described. The complete system includes a vector network analyzer, a microwave coaxial cable, the probe, a sample holder and a computer to automate measurements and further data processing. This system has been used to measure some liquid and solid materials such as alcohol, water and Teflon. The real and imaginary parts of permittivity as function of frequency, for several sugarcane alcohol and deionised water mixtures, tequilas and Teflon samples are given. Measurement repeatability and accuracy considerations were taken and it was identified that uncertainty of reference standards and system repeatability are the most important error sources. Also, it was found that open-ended coaxial probe technique is appropriate for measuring not only liquids but also solid materials. Some of the obtained results were compared to those reported in literature and good convergence was observed.

    1986-01-01

    This book is about power stations - specifically about the construction of modern power stations by the Central Electricity Generating Board in England and Wales over the past decade. It describes the work of the CEGB's Generation Development and Construction Division, perhaps better known throughout the world as simply 'Barnwood' where it has its Headquarters in Gloucester, UK. Barnwood was formed in the early 1970s to concentrate the CEGB's then dispersed engineering construction resources to cope with the smaller number but greatly increased size and complexity of modern power station projects. Perhaps uniquely over the ten years since its formation Barnwood has managed the construction of all types of station; coal-fired, oil-fired, nuclear, pumped storage and hydro. This book tells the story of these various projects and gives detailed descriptions of the respective stations. However, it is not intended as a comprehensive description of power station technology. Rather it is intended to convey the scale of such projects and the many decisions and compromises which have to be made in the course of managing their construction

    Aware of the increasing impact of human activities on the Earth system, Belgian Science Policy Office (Belspo) launched in 1997 a research programme in support of a sustainable development policy. This umbrella programme included the Belgian Scientific Programme on Antarctic Research. The International Polar Foundation, an organization led by the civil engineer and explorer Alain Hubert, was commissioned by the Belgian Federal government in 2004 to design, construct and operate a new Belgian Antarctic Research Station as an element under this umbrella programme. The station was to be designed as a central location for investigating the characteristic sequence of Antarctic geographical regions (polynia, coast, ice shelf, ice sheet, marginal mountain area and dry valleys, inland plateau) within a radius of 200 kilometers (approx.124 miles) of a selected site. The station was also to be designed as "state of the art" with respect to sustainable development, energy consumption, and waste disposal, with a minimum lifetime of 25 years. The goal of the project was to build a station and enable science. So first we needed some basic requirements, which I have listed here; plus we had to finance the station ourselves. Our most important requirement was that we decided to make it a zero emissions station. This was both a philosophical choice as we thought it more consistent with Antarctic Treaty obligations and it was also a logistical advantage. If you are using renewable energy sources, you do not have to bring in all the fuel.

    Full Text Available The crisis of modernity is particularly evident in the educational systems of advanced societies. These societies project on school systems more paradoxes and contradictions than they can really cope with. In the face of the deep transformations that concepts such as globalization, information and consumer society, postmodernity or reflexive modernity appear to claim, schools are losing their ability to successfully transmit models of identity and citizenship. This article explores the crisis of the socialising function of educational systems, and in particular the decline of the emancipatory goals this function is aimed at in its bureaucratic, systemic and communicative dimensions. In this way, the traditional strategies of socialization in advanced societies loose pace, and a restructuring is required. This restructuring should be tackled by departing from an eligibility horizon which in turn should be articulated by an ethos of desire.La crisis de la modernidad se manifiesta con gran crudeza en los sistemas educativos de las sociedades avanzadas, que proyectan sobre aquéllos más contradicciones y paradojas de las que pueden superar. Ante las profundas transformaciones invocadas por conceptos como globalización, sociedad de la información y/o del consumo, postmodernidad o modernidad reflexiva, las instituciones escolares están perdiendo su capacidad de transmitir modelos de identidad y ciudadanía eficazmente. Este trabajo explora la crisis de la función socializadora de los sistemas educativos, entendida como un declive sistémico, burocrático y comunicativo. De este modo, las clásicas estrategias de socialización propias de las sociedades modernas pierden su eficacia, siendo precisa su reconversión. Ésta puede ser afrontada orientando los procesos de socialización desde un horizonte de elegibilidad articulado por un ethos del deseo.

    Full Text Available This article aims to discuss the beginning of criminology in Argentina in the late nineteenth century and early twentieth century, to understand how it was articulated during the nation-state building process. To achieve this purpose, a state project reflection unfolded in criminological perspective that is based on legal positivism of the period was made. The country was forefront in interest in criminology in that some intellectuals jurists published numerous articles on the crime studies in the first criminology journal of Argentina, Criminalogia Moderna magazine, founded in 1898 and directed by the teacher, lawyer and intellectual Italian, Pietro Gori. The influence of European sociological perspective in Argentina criminology can be seen from a literature review. The examination of some articles published in the journal indicates how criminology introduced in Europe grounds the buenosairean intellectuality. Some authors have linked criminology with social phenomena of a nation increasingly industrialized, proletarianized, politicized and urbanized.

    Hydrogen fueling stations are an essential element in the practical application of hydrogen as a vehicle fuel, and a number of issues such as safety, efficiency, design, and operating procedures can only be accurately addressed by a practical demonstration. Regardless of whether the vehicle is powered by an internal combustion engine or fuel cell, or whether the vehicle has a liquid or gaseous fuel tank, the fueling station is a critical technology which is the link between the local storage facility and the vehicle. Because most merchant hydrogen delivered in the US today (and in the near future) is in liquid form due to the overall economics of production and delivery, we believe a practical refueling station should be designed to receive liquid. Systems studies confirm this assumption for stations fueling up to about 300 vehicles. Our fueling station, aimed at refueling fleet vehicles, will receive hydrogen as a liquid and dispense it as either liquid, high pressure gas, or low pressure gas. Thus, it can refuel any of the three types of tanks proposed for hydrogen-powered vehicles -- liquid, gaseous, or hydride. The paper discusses the fueling station design. Results of a numerical model of liquid hydrogen vehicle tank filling, with emphasis on no vent filling, are presented to illustrate the usefulness of the model as a design tool. Results of our vehicle performance model illustrate our thesis that it is too early to judge what the preferred method of on-board vehicle fuel storage will be in practice -- thus our decision to accommodate all three methods.

    Willits, Charles

    1990-01-01

    An ergonomic integration of controls, displays, and associated interfaces with an operator, whose body geometry and dynamics may be altered by the state of weightlessness, is noted to rank in importance with the optimal positioning of controls relative to the layout and architecture of 'body-ported' work/control stations applicable to the NASA Space Station Freedom. A long-term solution to this complex design problem is envisioned to encompass the following features: multiple imaging, virtual optics, screen displays controlled by a keyboard ergonomically designed for weightlessness, cursor control, a CCTV camera, and a hand-controller featuring 'no-grip' vernier/tactile positioning. This controller frees all fingers for multiple-switch actuations, while retaining index/register determination with the hand controller. A single architectural point attachment/restraint may be used which requires no residual muscle tension in either brief or prolonged operation.

  13. AS CONCEPÇÕES DE INFÂNCIA E AS TEORIAS EDUCACIONAIS MODERNAS E CONTEMPORÂNEAS

    Directory of Open Access Journals (Sweden)

    Paulo Ghiraldelli Jr

    2001-02-01

    Full Text Available O artigo aborda concepções de infância e as liga com a filosofia da educação. Em um primeiro momento o texto apresenta Descartes e Rousseau como pensadores modernos - eles abriram nossas mentes para a infância. Lembra que Nietzsche e Nabokov falaram de modo diferente sobre a infância. Mas todos falaram de uma "natureza da criança", boa ou má. Nossas histórias sobre a infância começaram a mudar porque o historicismo de Hegel, Collodi e Ariés solicitou uma infância feita pela sociedade e pela história. Ela não é boa nem má. O texto explica que a filosofia da educação seguiu esse modo moderno com Herbart, Dewey e Paulo Freire. Esses pensadores falaram sobre a infância e, mais ou menos, sobre uma "natureza da criança" - mas não radicalizaram essa idéia. Mas toda idéia sobre infância é rompida em uma era pós-moderna. Pós-modernismo diz: não precisamos de uma concepção de infância. Assim, podemos ter uma educação diferente e uma filosofia da educação diferente - sem discriminação. Leis protegem as crianças - isso estava junto com a idéia de "natureza da criança", mas a discriminação veio junto - ela veio com o conceito de infância. O Pós-modernismo diz adeus ao conceito de infância, e advoga que, sem ele, estamos em uma situação melhor.

    1989-01-01

    The Shippingport Atomic Power Station was located on the Ohio River in Shippingport Borough (Beaver County), Pennsylvania, USA. The US Atomic Energy Commission (AEC) constructed the plant in the mid-1950s on a seven and half acre parcel of land leased from Duquesne Light Company (DLC). The purposes were to demonstrate and to develop Pressurized Water Recovery technology and to generate electricity. DLC operated the Shippingport plant under supervision of (the successor to AEC) the Department of Energy (DOE)-Naval Reactors (NR) until operations were terminated on October 1, 1982. NR concluded end-of-life testing and defueling in 1984 and transferred the Station's responsibility to DOE Richland Operations Office (RL), Surplus Facility Management Program Office (SFMPO5) on September 5, 1984. SFMPO subsequently established the Shippingport Station Decommissioning Project and selected General Electric (GE) as the Decommissioning Operations Contractor. This report is intended to provide an overview of the Shippingport Station Decommissioning Project

    Myanmar is in a tectonically complex region between the eastern edge of the Himalayan collision zone and the northern end of the Sunda megathrust. Until recently, earthquake monitoring and research efforts have been hampered by a lack of modern instrumentation and communication infrastructure. In January 2016, a major upgrade of the Myanmar National Seismic Network (MNSN; network code MM) was undertaken to improve earthquake monitoring capability. We installed five permanent broadband and strong‐motion seismic stations and real‐time data telemetry using newly improved cellular networks. Data are telemetered to the MNSN hub in Nay Pyi Taw and archived at the Incorporated Research Institutions for Seismology Data Management Center. We analyzed station noise characteristics and site response using noise and events recorded over the first six months of station operation. Background noise characteristics vary across the array, but indicate that the new stations are performing well. MM stations recorded more than 20 earthquakes of M≥4.5 within Myanmar and its immediate surroundings, including an M 6.8 earthquake located northwest of Mandalay on 13 April 2016 and the Mw 6.8 Chauk event on 24 August 2016. We use this new dataset to calculate horizontal‐to‐vertical spectral ratios, which provide a preliminary characterization of site response of the upgraded MM stations.

    Space Station Freedom operations management concepts must be responsive to the unique challenges presented by the permanently manned international laboratory. Space Station Freedom will be assembled over a three year period where the operational environment will change as significant capability plateaus are reached. First Element Launch, Man-Tended Capability, and Permanent Manned Capability, represent milestones in operational capability that is increasing toward mature operations capability. Operations management concepts are being developed to accomodate the varying operational capabilities during assembly, as well as the mature operational environment. This paper describes operations management concepts designed to accomodate the uniqueness of Space Station Freedoom, utilizing tools and processes that seek to control operations costs.

  5. Principles of nuclear power station control

    International Nuclear Information System (INIS)

    Knowles, J.B.

    1975-12-01

    This memorandum represents lecture notes first distributed as part of a UKAEA introductory course on Reactor Technology held during November 1975. A nuclear power station is only one element of a dispersed interconnected arrangement of other nuclear and fossil-fired units which together constitute the national 'grid'. Thus the control of any one station must relate to the objectives of the grid network as a whole. A precise control of the supply frequency of the grid is achieved by regulating the output power of individual stations, and it is necessary for each station to be stable when operating in isolation with a variable load. As regards individual stations, several special control problems concerned with individual plant items are discussed, such as: controlled reactivity insertions, temperature reactivity time constants and flow instability. A simplified analysis establishes a fundamental relationship between the stored thermal energy of a boiler unit (a function of mechanical construction) and the flexibility of the heat source (nuclear or fossil-fired) if the station is to cope satisfactorily with demands arising from unscheduled losses of other generating sets or transmission capacity. Two basic control schemes for power station operation are described known as 'coupled' and 'decoupled control'. Each of the control modes has its own merits, which depend on the proposed station operating strategy (base load or load following) and the nature of the heat source. (U.K.)

Las nuevas obligaciones netas durante el ano ascendieron a 104,5 millones de dolares, es decir, un incremento de mas del 30% con respecto a 2005. En 2007 se celebra el 50{sup o} aniversario del OIEA, lo que brinda la oportunidad de examinar retrospectivamente la historia de las actividades de CT. Al principio, el programa de 'asistencia tecnica', como entonces se denominaba, era modesto: en 1960 la Junta de Gobernadores aprobo 28 proyectos en 16 Estados Miembros. Con el tiempo, la demanda de asistencia y competencia tecnica del Organismo ha aumentado sin cesar: el programa de CT que la Junta de Gobernadores aprobo en 2006 constaba de mas de 780 proyectos en 115 Estados Miembros. En los ultimos anos se ha experimentado en varios paises del mundo un cambio de las posturas respecto de la energia nucleoelectrica. El origen de esta tendencia se puede remontar al rapido aumento de la demanda de energia a escala mundial, el mayor enfasis en la seguridad energetica y una mayor sensibilizacion en cuanto a los riesgos del cambio climatico. Como consecuencia de ello, esta aumentando el numero de solicitudes de proyectos de planificacion energetica, una de cuyas opciones es la energia nucleoelectrica.

    DOE Technical Standard HDBK-1216-2015 (DOE 2015) recommends evaluating air-monitoring station placement using the analytical method developed by Waite. The technique utilizes wind rose and population distribution data in order to determine a weighting factor for each directional sector surrounding a nuclear facility. Based on the available resources (number of stations) and a scaling factor, this weighting factor is used to determine the number of stations recommended to be placed in each sector considered. An assessment utilizing this method was performed in 2003 to evaluate the effectiveness of the existing SRS air-monitoring program. The resulting recommended distribution of air-monitoring stations was then compared to that of the existing site perimeter surveillance program. The assessment demonstrated that the distribution of air-monitoring stations at the time generally agreed with the results obtained using the Waite method; however, at the time new stations were established in Barnwell and in Williston in order to meet requirements of DOE guidance document EH-0173T.

    Tournery, Jean-Francois

    2015-12-01

    As objectives of development are high for renewable energies (they are supposed to cover 50 per cent of new energy needs by 2035), pumped energy transfer stations are to play an important role in this respect. The author first discusses the consequences of the development of renewable energies on the exploitation of electric grids: issue of intermittency for some of them, envisaged solutions. Then, he addresses one of the solutions: the storage of electric power. He notices that increasing the potential energy of a volume of water is presently the most mature solution to face massive needs of the power system. Dams and pumped energy transfer stations represent now almost the whole installed storage power in the world. The author then presents these pumped energy transfer stations: principle, brief history (the first appeared in Italy and Switzerland at the end of the 1890's). He indicates the various parameters of assessment of such stations: maximum stored energy, installed power in pumping mode and turbine mode, time constant, efficiency, level of flexibility. He discusses economic issues. He describes and comments the operation of turbine-pump groups: ternary groups, reversible binary groups. He discusses barriers to be overcome and technical advances to be made for varying speed groups and for marine stations. He finally gives an overview (table with number of stations belonging to different power ranges, remarkable installations) of existing stations in China, USA, Japan, Germany, Austria, Spain, Portugal, Italy, Switzerland, France and UK, and indicate predictions regarding storage needs at the world level. Some data are finally indicated for the six existing French installations

    The Programa de Ahorro de Energia para el Sector Electrico (PAESE) (Program for Energy Conservation for the Electric Sector) in collaboration with the Instituto de Investigaciones Electricas (IIE), decided to evaluate technically and economically the possibilities of operating the Comision Federal de Electricidad`s Thermoelectric Power Stations (TPS), eventually to be retired as cogeneration units in supplying thermal energy to industry. The study was focussed to the Monterrey and San Jeronimo Power Stations, determining in a first stage, the optimum radius for handling and transporting steam and/or hot water and so to define the industries that potentially could obtain heat energy from the TPS, in this stage the thermal needs of the evaluated industries were determined (pressure, temperature and flow). In a second stage, the different arrangements to be made to operate the selected TPS, so as to be in position of satisfying such thermal energy demands were evaluated.

    The Programa de Ahorro de Energia para el Sector Electrico (PAESE) (Program for Energy Conservation for the Electric Sector) in collaboration with the Instituto de Investigaciones Electricas (IIE), decided to evaluate technically and economically the possibilities of operating the Comision Federal de Electricidad`s Thermoelectric Power Stations (TPS), eventually to be retired as cogeneration units in supplying thermal energy to industry. The study was focussed to the Monterrey and San Jeronimo Power Stations, determining in a first stage, the optimum radius for handling and transporting steam and/or hot water and so to define the industries that potentially could obtain heat energy from the TPS, in this stage the thermal needs of the evaluated industries were determined (pressure, temperature and flow). In a second stage, the different arrangements to be made to operate the selected TPS, so as to be in position of satisfying such thermal energy demands were evaluated. This paper presents the results of this study.

    The object is to provide a method of operating a dual purpose power station so that the steam supply system is operated at a high load factor. The available steam not required for electricity generation is used to provide process heat and the new feature is that the process plant capacity is determined to make the most economic use of the steam supply system, and not to match the passout capacity of the turbine of the turbogenerator. The product of the process plant should, therefore, be capable of being stored. A dual-purpose power station with a nuclear-powered steam source, turbogenerating means connected to the steam source and steam-powered process plant susceptible to wide variation in its rate of operation is described.

    Hydrogen is an environmentally attractive transportation fuel that has the potential to displace fossil fuels. The Freedom CAR and Freedom FUEL initiatives emphasize the importance of hydrogen as a future transportation fuel. Presently, Las Vegas has one hydrogen fueling station powered by natural gas. However, the use of traditional sources of energy to produce hydrogen does not maximize the benefit. The hydrogen fueling station developed under this grant used electrolysis units and solar energy to produce hydrogen fuel. Water and electricity are furnished to the unit and the output is hydrogen and oxygen. Three vehicles were converted to utilize the hydrogen produced at the station. The vehicles were all equipped with different types of technologies. The vehicles were used in the day-to-day operation of the Las Vegas Valley Water District and monitoring was performed on efficiency, reliability and maintenance requirements. The research and demonstration utilized for the reconfiguration of these vehicles could lead to new technologies in vehicle development that could make hydrogen-fueled vehicles more cost effective, economical, efficient and more widely used. In order to advance the development of a hydrogen future in Southern Nevada, project partners recognized a need to bring various entities involved in hydrogen development and deployment together as a means of sharing knowledge and eliminating duplication of efforts. A road-mapping session was held in Las Vegas in June 2006. The Nevada State Energy Office, representatives from DOE, DOE contractors and LANL, NETL, NREL were present. Leadership from the National hydrogen Association Board of Directors also attended. As a result of this session, a roadmap for hydrogen development was created. This roadmap has the ability to become a tool for use by other road-mapping efforts in the hydrogen community. It could also become a standard template for other states or even countries to approach planning for a hydrogen

  14. Safety Distances for hydrogen filling stations

    Energy Technology Data Exchange (ETDEWEB)

    Matthijsen, A. J. C. M.; Kooi, E. S.

    2005-07-01

    In the Netherlands there is a growing interest in using natural gas as a transport fuel. The most important drivers behind this development are formed by poor inner city air quality and the decision to close several LPG filling stations. Dwellings are not allowed within the safety distances of 45 or 110 meters from the tanker filling point of these LPG stations, depending on the capacity of the station. Another driver is global warming. We are carrying out a study on station supply, compression, storage and filling for natural gas stations, and a similar, simultaneous study on hydrogen as a followup to our risk analysis for the hydrogen filling station in Amsterdam. Here, three buses drive on hydrogen as part of the European CUTE project. Driving on natural gas is an important step in the transition to cars on hydrogen. This study was commissioned by the Dutch Ministry of Spatial Planning, Housing and the Environment to advise on external safety aspects of future hydrogen filling stations. According to Dutch law homes may not be built within an individual risk contour of 10-6 per year of a dangerous object, such as a plant with hazardous materials or a filling station. An individual risk contour of 10-6 is represented by a line around a dangerous object that connects locations with an individual risk level of 10-6 per year. An individual 'located' within this contour line has a chance of one per million per year or more to be killed as a result of an accident caused by this object. The longest distance between the object and such a contour is called a 'safety distance'. A study on safety distances is now in progress for different kinds of hydrogen filling stations (e. g. gaseous and liquid hydrogen) and for different capacities, such as big, medium and small stations. The focus is on different kinds of hydrogen production and the hydrogen supply of the filling station. To decide on the design and supply of the hydrogen station, we examined the

The Instituto Antartico Chileno (INACH kindly gave me a chance to stay in Frei/Escudero Bases as an exchange scientist under the Antarctic Treaty for two weeks in January 2000. I stayed in Frei Base as a member of a geological survey group named "Tectonic Evolution of the Antarctic Peninsula" which was organized by Prof. F. Herve, University of Chile, from January 05 to 19,2000. All my activity in the Antarctic was organized by INACH. During my stay in Frei Base, I also visited Bellingshausen (Russian, Great Wall (China and Artigas (Uruguay stations. All these stations are located within walking distance of Frei Base. King Sejong Station (Korea, located 10km east from Frei Base, and Jubany Base (Argentine, another 6km south-east from King Sejong Station, were also visited with the aid of a zodiac boat that was kindly operated for us by King Sejong Station. All stations except Escudero Base carry out meteorological observations. The seismological observations in Frei Base are operated by Washington State University of the U. S. monitoring of earthquake activity and three-component geomagnetic observations are done at King Sejong and Great Wall stations. Earth tide is monitored at Artigas Base.

    One of the technical challenges of hydrogen technology is the development of hydrogen infrastructures which satisfy either safety requirements and reliability of filling processes. AIR LIQUIDE realized an hydrogen filling station in Sassenage (France) operational since September 2003. This station is able to fill 3 buses a day up to 350bar by equilibrium with high pressure buffers. In parallel with commercial stations, the group wanted to create a testing ground in real conditions running with several objectives: validate on a full scale bench a simulation tool able to predict the temperature of both gas and cylinder's materials during filling processes; define the best filling procedures in order to reach mass, temperature and filling time targets; analyse the temperature distribution and evolution inside the cylinder; get a general knowledge about hydrogen stations from safety and reliability point of view; operate the first full scale refuelling station in France. The station is also up-graded for 700bar filling from either a liquid hydrogen source or a gas booster, with cold filling possibility. This paper presents the results concerning 350bar filling : thermal effects, optimal filling procedures and influence of parameters such as climatic conditions are discussed. (author)

    2015-09-01

    The scope of this project was changed during the course of the project. Phase I of the project was to construct a site similar to the site at Central West Virginia Regional Airport in Charleston, WV to show that duplication of the site was a feasible method of conducting hydrogen stations. Phase II of the project was necessitated due to a lack of funding that was planned for the development of the station in Morgantown. The US Department of Energy determined that the station in Charleston would be dismantled and moved to Morgantown and reassembled at the Morgantown site. This necessitated storage of the components of the station for almost a year at the NAFTC Headquarters which caused a number of issues with the equipment that will be discussed in later portions of this report. This report will consist of PHASE I and PHASE II with discussions on each of the tasks scheduled for each phase of the project.

  12. Background noise spectra of global seismic stations

    Energy Technology Data Exchange (ETDEWEB)

    Wada, M.M.; Claassen, J.P.

    1996-08-01

    Over an extended period of time station noise spectra were collected from various sources for use in estimating the detection and location performance of global networks of seismic stations. As the database of noise spectra enlarged and duplicate entries became available, an effort was mounted to more carefully select station noise spectra while discarding others. This report discusses the methodology and criteria by which the noise spectra were selected. It also identifies and illustrates the station noise spectra which survived the selection process and which currently contribute to the modeling efforts. The resulting catalog of noise statistics not only benefits those who model network performance but also those who wish to select stations on the basis of their noise level as may occur in designing networks or in selecting seismological data for analysis on the basis of station noise level. In view of the various ways by which station noise were estimated by the different contributors, it is advisable that future efforts which predict network performance have available station noise data and spectral estimation methods which are compatible with the statistics underlying seismic noise. This appropriately requires (1) averaging noise over seasonal and/or diurnal cycles, (2) averaging noise over time intervals comparable to those employed by actual detectors, and (3) using logarithmic measures of the noise.

    In this paper are designed an analyzed the control ties of a 300MW fossil unit at different operation levels. The design and analysis were developed on an operation range of 50% to 100% load. The main control ties were studied among which are the feedwater flow, the superheating zone temperatures and the generated output. The technique used for the design is the decomposition in singular values (DSV) of the plant transference matrix. This is a recent technique that permits finding the most important interactions among output-input variables, over a significative frequencies range for the transference matrix of the plant. For this purpose utilizes the control properties of the transference matrix, such as: control effort, output-input interaction and ruggedness with respect to uncertainties. The control structures obtained were tested in a digital model of a fossil plant unit. A comparison study of both structures (original and modified) showed enhancement in the performance of the power plant with modified structure.

    To compare the accuracy of digital assessment and the StationMaster (SM) in the assessment of fetal head station. The SM is a simple modification of the amniotomy hook which works by relocating the point of reference for station assessment from the ischial spines to the posterior fourchette. It is first adjusted to the woman's pelvic size, and then inserted into the vagina until it touches the fetal head. The station is then read off at the posterior fourchette in cm. An in vitro study of test validity and reliability was conducted at Liverpool Women's Hospital, Liverpool, UK. An apparatus was constructed in which a model fetal head could be accurately positioned within a mannequin's pelvis. Twenty midwives and 20 doctors (in current labour ward practice) gave their consent to take part. First, the head was placed in 5 random stations (-2 to +7 cm) and the participant asked to record their digital assessment for each. The participant was then taught to use the SM and the experiment repeated with 5 new stations. The complete experiment was repeated at least 2 weeks later using the same stations but in reverse order. The true values were compared with both the digital and SM assessments using mean differences with 95% limits of agreement. The repeatability of the two methods was assessed in the same way. Overall, the SM was more accurate than digital examination. The mean error (S.D.) ranged from 0.1 (1.2) to 2.6 (1.6) for the StationMaster and 0.3 (1.3) to 4.3 (1.1) for digital examination. Inaccuracies increased as the head descended through the pelvis. When assessed digitally, the true value fell outside one standard deviation for stations of more than +1cm. In contrast, with the SM the true value remained inside one standard deviation for all stations up to +5. In vitro the SM improves the accuracy of intrapartum station assessment.

  19. Utilities respond to nuclear station blackout rule

    International Nuclear Information System (INIS)

    Rubin, A.M.; Beasley, B.; Tenera, L.P.

    1990-01-01

    The authors discuss how nuclear plants in the United States have taken actions to respond to the NRC Station Blackout Rule, 10CFR50.63. The rule requires that each light water cooled nuclear power plant licensed to operate must be able to withstand for a specified duration and recover from a station blackout. Station blackout is defined as the complete loss of a-c power to the essential and non-essential switch-gear buses in a nuclear power plant. A station blackout results from the loss of all off-site power as well as the on-site emergency a-c power system. There are two basic approaches to meeting the station blackout rule. One is to cope with a station blackout independent of a-c power. Coping, as it is called, means the ability of a plant to achieve and maintain a safe shutdown condition. The second approach is to provide an alternate a-c power source (AAC)

    2009-10-01

    Full Text Available RESUMEN: A lo largo de la Edad Moderna los Estados Pontificios mantuvieron una naturaleza compleja, caracterizada por fuertes tradiciones municipales, amplios poderes feudales y la herencia de los ducados que habían pertenecido a dinastías extintas, como el caso de Ferrara y Urbino. Todo ello condicionó el gobierno romano en los distintos lugares. También fue necesario adaptar las diversas clases de justicia —laica, eclesiástica, distributiva y conmutativa— a las circunstancias locales, sin comprometer la autoridad del Papa o de sus representantes. En este proyecto político de dominación del territorio, Roma y su sistema de justicia se propusieron como modelo para el conjunto de los Estados Pontificios. El control del orden y de la administración de justicia, sinónimos de buen gobierno y factores determinantes para mantener el consenso hacia el poder papal, se manifestaron en la adaptación de la norma y de la práctica a la realidad local, como prueba la correspondencia de las congregaciones romanas —la Sacra Consulta, el Buon Governo, la Inquisición— con los funcionarios judiciales periféricos.ABSTRACT: Throughout the early modern period the Papal States maintained their composite nature; characterized by territories with strong traditions of local government, extensive feudal powers and by the inheritance of duchies that had belonged to dynasties that had become extinct, as happened in the cases of Ferrara and Urbino. These characteristics of the papal dominions strongly determined the nature of Roman government in the localities. Also very necessary was the need to adapt different kinds of justice —lay, ecclesiastical, distributive and commutative— to these local conditions, without compromising the authority of the pope or that of his representatives. In this political project of territorial domination, Rome and its system of justice was put forward as a model for the entire Papal States. Control of law and order and

    A conveyor system comprises carriages drive, e.g. by a linear motor, a pre-arranged sequence of steps to move workpieces in forward and reverse directions between work stations. Each work station has a part position and a work position and each carriage has a number of compartments for workpieces spaced apart at a pitch equal to the spacing between the part and work positions at each station. Transfer means at the work stations move workpieces between the carriage compartments and the part and work positions. The workpieces can be nuclear fuel pins mounted in carriers and the carriages shuttle to and fro between adjacent stations to move fuel pins and carriers in a forward direction and the return empty carriers in a reverse direction.

    2008-01-01

    In 2006, TEPCO submitted to the government plans for the construction of Higashidori Nuclear Power Station. The application was filed 41 years after the project approved by the Higashidori Village Assembly. This nuclear power station will be the first new nuclear power plant constructed by TEPCO since the construction of Units No.6 and 7 at the Kashiwazaki Kariwa Nuclear Power Station 18 years ago. Higashidori Nuclear Power Station is to be constructed at a completely new site, which will become the fourth TEPCO nuclear power station. Higashidori Nuclear Power Station Unit No.1 will be TEPCO's 18th nuclear reactor. Unit No.1 will be an advanced boiling water reactor (ABWR), a reactor-type with a proven track record. It will be TEPCO's third ABWR. Alongside incorporating the latest technology, in Higashidori Nuclear Power Station Unit No.1, the most important requirement is for TEPCO to reflect in the new unit information and experience acquired from the operation of other reactors (information and experience acquired through the experience of operating TEPCO's 17 units at Fukushima Daiichi Nuclear Power Station, Fukushima Daini Nuclear Power Station and Kashiwazaki Kashiwa Nuclear Power Station in addition to information on non-conformities at nuclear power stations in Japan and around the world). Higashidori Nuclear Power Station is located in Higashidori-Village (Aomori Prefecture) and the selected site includes a rich natural environment. From an environmental perspective, we will implement the construction with due consideration for the land and sea environment, aiming to ensure that the plant can co-exist with its natural surroundings. The construction plans are currently being reviewed by the Nuclear and Industrial Safety Agency. We are committed to making progress in the project for the start of construction and subsequent commercial operation. (author)

    Oak Ridge National Laboratory (ORNL) has been awarded $6.8 million in the Department of Energy (DOE) American Recovery and Reinvestment Act (ARRA) funds as part of an overall $114.8 million ECOtality grant with matching funds from regional partners to install 125 solar-assisted Electric Vehicle (EV) charging stations across Knoxville, Nashville, Chattanooga, and Memphis. Significant progress has been made toward completing the scope with the installation of 25 solar-assisted charging stations at ORNL; six stations at Electric Power Research Institute (EPRI); and 27 stations at Nissan's Smyrna and Franklin sites, with three more stations under construction at Nissan's new lithium-ion battery plant. Additionally, the procurement process for contracting the installation of 34 stations at Knoxville, the University of Tennessee Knoxville (UTK), and Nashville sites is underway with completion of installation scheduled for early 2012. Progress is also being made on finalizing sites and beginning installations of 30 stations in Nashville, Chattanooga, and Memphis by EPRI and Tennessee Valley Authority (TVA). The solar-assisted EV charging station project has made great strides in fiscal year 2011. A total of 58 solar-assisted EV parking spaces have been commissioned in East and Middle Tennessee, and progress on installing the remaining 67 spaces is well underway. The contract for the 34 stations planned for Knoxville, UTK, and Nashville should be underway in October with completion scheduled for the end of March 2012; the remaining three Nissan stations are under construction and scheduled to be complete in November; and the EPRI/TVA stations for Chattanooga, Vanderbilt, and Memphis are underway and should be complete by the end of March 2012. As additional Nissan LEAFs are being delivered, usage of the charging stations has increased substantially. The project is on course to complete all 125 solar-assisted EV charging stations in time to collect meaningful data

Aún se debate hasta dónde ésta variabilidad se ha acumulado a través de procesos neutrales (e.g. deriva genética o bien por efecto de la selección natural. Entender los procesos evolutivos que dieron origen a esta variación es una de las metas de la biología humana en particular y de la biología evolutiva en general. Para analizar la relación entre los patrones de cambio y variación morfológica observados y los esperados bajo un escenario de evolución neutral, aplicamos un modelo genético cuantitativo sobre una muestra muy amplia de poblaciones que abarcan el continente Americano, Asia y Oceanía. La morfología craneofacial se estudió a partir de medidas lineales correspondientes al método craneofuncional, en donde treinta variables métricas describen los distintos componentes funcionales observables en el cráneo. Los resultados indican que los procesos aleatorios, tales como la deriva genética, no son suficientes para explicar la variación morfológica del cráneo en las poblaciones humanas modernas.

    2010-12-01

    Full Text Available Measurement of atmospheric black carbon (BC was carried out at Syowa Station Antarctica (69゜00′S, 39゜35′E from February 2004 until January 2007. The BC concentration at Syowa Station ranged from below detection to 176 ng m^. Higher BC concentrations were observed frequently from April until October. Increase of BC concentration may be associated with poleward flow due to the approach of a cyclone and or blocking event during winter-spring. The BC-rich air masses traveled through the lower troposphere from the Atlantic and Indian Oceans to Syowa (Antarctic coast. During the summer (November-February, the BC concentration showed a diurnal variation together with surface wind speed and increased in the presence of katabatic wind from the Antarctic continent. Considering the low BC source strength over the Antarctic continent, the higher BC concentration in the continental air (katabatic wind might be caused by long range transport of BC via the free troposphere from mid- and low- latitudes. The seasonal variation of BC at Syowa Station had a maximum in July-September, while at the other coastal stations (Halley, Neumayer, and Ferraz and a continental station (Amundsen-Scott, the maximum occurred in October. This difference may result from different transport pathways, significant contribution of source regions and scavenging of BC by precipitation during the transport from the source regions. During the austral summer, long-range transport of BC via the free troposphere is likely to make an important contribution to the ambient BC concentration along the Antarctic coasts.

    BOC Canada Ltd. will design, integrate and construct the second fueling station on the Hydrogen Highway. This station will be located at the National Research Council's Institute for Fuel Cell Innovation on the campus of the University of British Columbia. BOC's design will bring together an existing alkaline electrolyser, new compression, storage and dispensing. The station will be designed to serve fuel cell passenger vehicles using 350-bar storage. However, the flexible design concept will allow for many other user needs including the potential for servicing larger vehicles, as well as filling portable storage systems for use at satellite stations. The novel station design also offers the potential to fuel from multiple hydrogen sources. Together with NRC, this fueling station will be used to increase public, consumer and investor awareness of hydrogen technologies. Design and construction of this facility will assist in the development of industry codes and standards and familiarize authorities having jurisdiction with hydrogen fueling. The system concept offers the utmost attention to safety, novelty and flexibility. (author)

    Diaz, Alphonso V.; Askins, Barbara S.

    1987-06-01

    The need for permanently manned presence in space has been recognized by the United States and its international partners for many years. The development of this capability was delayed due to the concurrent recognition that reusable earth-to-orbit transportation was also needed and should be developed first. While the decision to go ahead with a permanently manned Space Station was on hold, requirements for the use of the Station were accumulating as ground-based research and the data from unmanned spacecraft sparked the imagination of both scientists and entrepreneurs. Thus, by the time of the Space Station implementation decision in the early 1980's, a variety of disciplines, with a variety of requirements, needed to be accommodated on one Space Station. Additional future requirements could be forecast for advanced missions that were still in the early planning stages. The logical response was the development of a multi-purpose Space Station with the ability to evolve on-orbit to new capabilities as required by user needs and national or international decisions, i.e., to build an evolutionary Space Station. Planning for evolution is conducted in parallel with the design and development of the baseline Space Station. Evolution planning is a strategic management process to facilitate change and protect future decisions. The objective is not to forecast the future, but to understand the future options and the implications of these on today's decisions. The major actions required now are: (1) the incorporation of evolution provisions (hooks and scars) in the baseline Space Station; and (2) the initiation of an evolution advanced development program.

    The U.S. Department of Energy is in the process of decommissioning the Shippingport Atomic Power Station located on the Ohio River, 30 miles northwest of Pittsburgh, Pennsylvania. The Shippingport Station is the first commercial size nuclear power plant to undergo decommissioning in the United Staes. The plant is located on approximately 7 acres of land owned by the Duquesne Light Company (DLC) and leased to the U.S. Government. DLC operates two nuclear power plants, Beaver Valley 1 and 2, located immediately adjacent to the site and the Bruce Mansfield coal-fired power plant is also within the immediate area. The Station was shutdown in October, 1982. Defueling operations began in 1983 and were completed by September, 1984. The Shippingport Station consists of a 275' x 60' fuel handling building containing the reactor containment chamber, the service building, the turbine building, the radioactive waste processing building, the administration building and other smaller support buildings. The Station has four coolant loops and most of the containment structures are located below grade. Structures owned by the U.S. Government including the fuel handling building, service building, contaminated equipment room, the boiler chambers, the radioactive waste processing building and the decontamination and laydown buildings will be dismantled and removed to 3 feet below grade. The area will then be filled with clean soil and graded. The turbine building, testing and training building and the administration building are owned by DLC and will remain

    The action of Electricite de France with respect to the environment of PWR nuclear power stations is essentially centred on prevention. Controls are carried out at two levels: - before the power station goes on stream (radioecological study), - when the power station is operational. The purpose of the controls effected on the radioactive effluents and the environment is to check that the maximum discharge rate stipulated in the corresponding orders is complied with and to ensure that there are no anomalies in the environment [fr

    1980-01-01

    Federal market development strategies designed to accelerate the market penetration of central station applications of photovoltaic energy system are analyzed. Since no specific goals were set for the commercialization of central station applications, strategic principles are explored which, when coupled with specific objectives for central stations, can produce a market development implementation plan. The study includes (1) background information on the National Photovoltaic Program, photovoltaic technology, and central stations; (2) a brief market assessment; (3) a discussion of the viewpoints of the electric utility industry with respect to solar energy; (4) a discussion of commercialization issues; and (5) strategy principles. It is recommended that a set of specific goals and objectives be defined for the photovoltaic central station program, and that these goals and objectives evolve into an implementation plan that identifies the appropriate federal role.

    To investigate the impact of subway station design on platform noise levels. Observational. Continuous A-weighted decibel (dBA) sound levels were recorded in 20 New York City subway stations, where trains entered on either a straight track or curved track in 10 stations each. Equivalent continuous noise levels (L eq ) at various locations on the boarding platform (inbound end, midplatform, and outbound end) during train entry and exit were compared between the straight and curved stations in broadband as well as narrow one-third octave bands. Overall, curved stations trended louder than straight stations, although the difference in broadband L eq did not reach statistical significance (curve, 83.4 dBA; straight, 82.6 dBA; P = .054). Noise levels were significantly louder at the inbound end of the platform during train entry (inbound, 89.7 dBA; mid, 85.5 dBA; outbound, 78.7 dBA; P < .001) and at the outbound end during train exit (inbound, 79.7 dBA; mid, 85.3 dBA; outbound, 89.1 dBA; P < .001). Narrow band analysis showed that curved stations were significantly louder than straight stations at 100 Hz and high frequencies from 8 to 20 kHz. Peak impact levels ranged from 104 to 121 dBA. Curved stations have a different noise profile compared to straight stations and are significantly louder than straight stations at high frequencies. Designing stations with straight tracks within the platform can help reduce commuter noise exposure.

    Giudici, R.J.

    1985-01-01

    Issues governing the selection of power systems for long-term manned Space Stations intended solely for earth orbital missions are covered briefly, drawing on trade study results from both in-house and contracted studies that have been conducted over nearly two decades. An involvement, from the Program Development Office at MSFC, with current Space Station concepts began in late 1982 with the NASA-wide Systems Definition Working Group and continued throughout 1984 in support of various planning activities. The premise for this discussion is that, within the confines of the current Space Station concept, there is good reason to consider photovoltaic power systems to be a venerable technology option for both the initial 75 kW and 300 kW (or much greater) growth stations. The issue of large physical size required by photovoltaic power systems is presented considering mass, atmospheric drag, launch packaging and power transmission voltage as being possible practicality limitations. The validity of searching for a cross-over point necessitating the introduction of solar thermal or nuclear power system options as enabling technologies is considered with reference to programs ranging from the 4.8 kW Skylab to the 9.5 gW Space Power Satellite

    1997-12-01

    This paper discusses the concept of battery charging stations (BCSs), designed to service rural owners of battery power sources. Many such power sources now are transported to urban areas for recharging. A BCS provides the opportunity to locate these facilities closer to the user, is often powered by renewable sources, or hybrid systems, takes advantage of economies of scale, and has the potential to provide lower cost of service, better service, and better cost recovery than other rural electrification programs. Typical systems discussed can service 200 to 1200 people, and consist of stations powered by photovoltaics, wind/PV, wind/diesel, or diesel only. Examples of installed systems are presented, followed by cost figures, economic analysis, and typical system design and performance numbers.

    Mallary, William E.; Whitelaw, Virginia A.

    1987-01-01

    Within the Space Station program, the Data Management System (DMS) functions in a dual role. First, it provides the hardware resources and software services which support the data processing, data communications, and data storage functions of the onboard subsystems and payloads. Second, it functions as an integrating entity which provides a common operating environment and human-machine interface for the operation and control of the orbiting Space Station systems and payloads by both the crew and the ground operators. This paper discusses the evolution and derivation of the requirements and issues which have had significant effect on the design of the Space Station DMS, describes the DMS components and services which support system and payload operations, and presents the current architectural view of the system as it exists in October 1986; one-and-a-half years into the Space Station Phase B Definition and Preliminary Design Study.

    1997-01-01

    Ontario Hydro's Darlington Nuclear Generating Station (4x881MW(e)net) has carried out its first station outage since full commercial operation. The outage presented challenges to the organization in terms of outage planning, support, management, and safe execution within the constraints of schedule, budget and resources. This paper will focus on the success of the outage maintenance program, identifying the major work programs - a vacuum structure and containment outage, an emergency service water system outage, an emergency coolant injection system outage, intake channel inspections, low pressure service water inspections, and significant outage maintenance work on each of the four reactor units. Planning for the outage was initiated early in anticipation of this important milestone in the station's life. Detailed safety reviews - nuclear, radiation, and conventional - were conducted in support of the planned maintenance program. System lineup and work protection were provided by the Station Operator work group. Work protection permitry was initiated well in advance of the outage. Station maintenance staff resources were bolstered in support of the outage to ensure program execution could be maintained within the schedule. Training programs were in place to ensure that expectations were clear and that high standards would be maintained. Materials management issues in support of maintenance activities were given high priority to ensure no delays to the planned work. Station management review and monitoring in preparation for and during the outage ensured that staff priorities remained focused. Lessons learned from the outage execution are being formalized in maintenance procedures and outage management procedures, and shared with the nuclear community. (author)

    Science.gov (United States)

    Wassersug, R

    1994-08-01

    This essay explores the pros and cons of maximizing the number of species that can be maintained on the Space Station. It reviews some of the history of comparative space biology to show that different cultures have different perspectives on the study of non-traditional research organisms (ie non-rodents) in space. Despite these differences, there are simple principles that all international partners in the Space Station endeavour should be able to uphold when deciding what facilities to build and what species to fly. As an argument for maximizing the taxonomic diversity on the Space Station, examples are given to show how very similar organisms may have different reactions to microgravity. At the same time the political pressure in the USA to make the Space Station an institution specifically servicing the 'health, well-being and economic benefits of people on earth', is acknowledged. Ultimately the justification for what species will be on the Space Station should rest with the quality of the scientific questions being asked.

    The purpose of this study is to establish 'error management process for power stations' for systematizing activities for human error prevention and for festering continuous improvement of these activities. The following are proposed by deriving concepts concerning error management process from existing knowledge and realizing them through application and evaluation of their effectiveness at a power station: an entire picture of error management process that facilitate four functions requisite for maraging human error prevention effectively (1. systematizing human error prevention tools, 2. identifying problems based on incident reports and taking corrective actions, 3. identifying good practices and potential problems for taking proactive measures, 4. prioritizeng human error prevention tools based on identified problems); detail steps for each activity (i.e. developing an annual plan for human error prevention, reporting and analyzing incidents and near misses) based on a model of human error causation; procedures and example of items for identifying gaps between current and desired levels of executions and outputs of each activity; stages for introducing and establishing the above proposed error management process into a power station. By giving shape to above proposals at a power station, systematization and continuous improvement of activities for human error prevention in line with the actual situation of the power station can be expected.

    We have investigated the average P-wave travel-time residuals for some stations around Southern Thailand, Peninsular Malaysia and Singapore at regional distances. Six years (January, 2010-December, 2015) record of events from central and northern Sumatra was obtained from the digital seismic archives of Integrated Research Institute for Seismology (IRIS). The criteria used for the data selection are designed to be above the magnitude of mb 4.5, depth less than 200 km and an epicentral distance shorter than 1000 km. Within this window a total number of 152 earthquakes were obtained. Furthermore, data were filtered based on the clarity of the seismic phases that are manually picked. A total of 1088 P-wave arrivals and 962 S-wave arrivals were hand-picked from 10 seismic stations around the Peninsula. Three stations IPM, KUM, and KOM from Peninsular Malaysia, four stations BTDF, NTU, BESC and KAPK from Singapore and three stations SURA, SRIT and SKLT located in the southern part of Thailand are used. Station NTU was chosen as the Ref. station because it recorded the large number of events. Travel-times were calculated using three 1-D models (Preliminary Ref. Earth Model PREM (Dziewonski and Anderson, 1981, IASP91, and Lienert et al., 1986) and an adopted two-point ray tracing algorithm. For the three models, we corroborate our calculated travel-times with the results from the use of TAUP travel-time calculation software. Relative to station NTU, our results show that the average P wave travel-time residual for PREM model ranges from -0.16 to 0.45 s for BESC and IPM respectively. For IASP91 model, the average residual ranges from -0.25 to 0.24 s for SRIT and SKLT respectively, and ranges from -0.22 to 0.30 s for KAPK and IPM respectively for Lienert et al. (1986) model. Generally, most stations have slightly positive residuals relative to station NTU. These corrections reflect the difference between actual and estimated model velocities along ray paths to stations and

    Methicillin-resistant Staphylococcus aureus (MRSA) has caused a series of public health problems since it was first found in 1961. However, there are few research studies on the MRSA environmental contamination in railway stations and coach stations. Therefore, the aim of this study was to determine MRSA environmental contamination in public transport stations. Between December 2013 and January 2014, 380 surface samples from three railway stations (180) and four coach stations (200) in Guangzhou were collected to isolate and determine the prevalence and characteristics of Staphylococci strains. 39·21% of all samples were Staphylococci isolates, 1·58% of Staphylococci isolates were MRSA isolates, and 6·05% were methicillin-susceptible S. aureus. The proportion of multidrug resistant among 149 Staphylococci isolates was 75·84%. None of MRSA isolates was identified with the Panton-Valentine Leukocidin (PVL) genes, and one of them was identified with the qac gene. Four MRSA isolates were Staphylococcal Cassette Chromosome mec IVa, and the other two were nontypeable. Staphylococcus aureus isolates were classified into several sequence types (STs), and STs showed possible cross-transmissions of isolates from various sources. Methicillin-resistant Staphylococci contamination prevalence was high, and the environment of stations may be the vectors transmitting the Staphylococci to passengers. This is the first study to comprehensively report the prevalence, antibiotic resistance, and molecular characteristics of contamination of Staphylococci isolates in railway stations and coach stations of China. It will have great public health implications on infection control in community settings because of the serious hazard of Staphylococci, especially methicillin-resistant Staphylococci. Our findings have provided evidence for relevant departments to reduce the contamination of Staphylococci in environment of public transport stations. © 2016 The Society for Applied

    2017-12-01

    Six-component measurements of seismic ground motion provide a unique opportunity to identify and decompose seismic wavefields into different wave types and incoming azimuths, as well as estimate structural information (e.g., phase velocity). By using the relationship between the transverse component and vertical rotational motion for Love waves, we can find the incident azimuth of the wave and the phase velocity. Therefore, when we scan the entire range of azimuth and slownesses, we can process the seismic waves in a similar way to conventional beamforming processing, without using a station array. To further improve the beam resolution, we use the distribution of amplitude ratio between translational and rotational motions at each time sample. With this beamforming, we decompose multiple incoming waves by azimuth and phase velocity using only one station. We demonstrate this technique using the data observed at Wettzell (vertical rotational motion and 3C translational motions). The beamforming results are encouraging to extract phase velocity at the location of the station, apply to oceanic microseism, and to identify complicated SH wave arrivals. We also discuss single-station beamforming using other components (vertical translational and horizontal rotational components). For future work, we need to understand the resolution limit of this technique, suitable length of time windows, and sensitivity to weak motion.

Problematizando, primeiramente o marco histórico, o argumento central aponta que a Paz de Vestfália não promoveu profunda inovação nem ruptura em relação à perspectiva anterior à Guerra dos Trinta Anos no que diz respeito aos aspectos essenciais das unidades constitutivas do Sacro Império Romano e das prerrogativas do imperador, apenas confirmou uma ordem cooperativa legal de entidades autônomas não-soberanas. O questionamento da existência empírica de um sistema inviolável de Estados soberanos evidencia, a seguir, as brechas nos princípios de autonomia e de territorialidade do modelo vestfaliano de relações internacionais. Finalmente, as interpretações alternativas do impacto da Paz de Vestfália para as relações internacionais e para seu estudo indicam que a igualdade formal entre os Estados intensifica dificuldades na resposta às diferenças na cultura, na religião e no modo de vida.

  1. A distributed planning concept for Space Station payload operations

    Science.gov (United States)

    Hagopian, Jeff; Maxwell, Theresa; Reed, Tracey

    1994-01-01

    The complex and diverse nature of the payload operations to be performed on the Space Station requires a robust and flexible planning approach. The planning approach for Space Station payload operations must support the phased development of the Space Station, as well as the geographically distributed users of the Space Station. To date, the planning approach for manned operations in space has been one of centralized planning to the n-th degree of detail. This approach, while valid for short duration flights, incurs high operations costs and is not conducive to long duration Space Station operations. The Space Station payload operations planning concept must reduce operations costs, accommodate phased station development, support distributed users, and provide flexibility. One way to meet these objectives is to distribute the planning functions across a hierarchy of payload planning organizations based on their particular needs and expertise. This paper presents a planning concept which satisfies all phases of the development of the Space Station (manned Shuttle flights, unmanned Station operations, and permanent manned operations), and the migration from centralized to distributed planning functions. Identified in this paper are the payload planning functions which can be distributed and the process by which these functions are performed.

    This report presents near-term station cost results and discusses cost trends of different station types. It compares various vehicle rollout scenarios and projects realistic near-term station utilization values using the station infrastructure rollout in California as an example. It describes near-term market demands and matches those to cost-effective station concepts. Finally, the report contains detailed designs for five selected stations, which include piping and instrumentation diagrams, bills of materials, and several site-specific layout studies that incorporate the setbacks required by NFPA 2, the National Fire Protection Association Hydrogen Technologies Code. This work identified those setbacks as a significant factor affecting the ability to site a hydrogen station, particularly liquid stations at existing gasoline stations. For all station types, utilization has a large influence on the financial viability of the station.

  3. Study of the method of placing technical stations

    Directory of Open Access Journals (Sweden)

    Sattorov S.B.

    2017-12-01

    Full Text Available At present, the organization of transportation by rail is associated with the processing of trains and wagons along the route. Accommodation and equipping of technical stations play a major role in the organization of the transportation process. The uninterrupted operation of the technical stations ensures the stability of the railway transport as a whole. The distance between the technical stations determines the duration of operation of the locomotive crew, the efficient use of the locomotive, the required number of locomotive crews and locomotives for carrying out the transportation plan, and also improves the main indicators of the railway. However, often train locomotives do not fulfill their assigned tasks due to the lack of time for the locomotive crew in order to deliver the train to the nearest technical station, as well as the irrational use of the standard time of the locomotive crew. In connection with the expectation of delivery, the locomotive brigade replacing the locomotive, the idle time of the wagons at the intermediate stations increases. All this makes it difficult to control the movement of trains and reduces the speed of moving cars on the railway transport. The purpose of the study is to develop a method for placing technical stations on a railway test site in the course of an electric traction. To achieve this goal, it will be necessary to solve the following tasks: generalization of the main parameters of the location of technical stations; determination of half-races between technical stations in the operation of one locomotive brigade; search for the required number of change of the locomotive brigade; determination of the distance between technical stations. The methods of research are based on the generalization and analysis of existing results in finding the rational location of technical stations. Results: It is revealed that the first step for the rational placement of technical stations is to determine the

  4. Station black out of Fukushima Daiichi Nuclear Power Station Unit 1 was not caused by tsunamis

    Ito, Yoshinori

    2013-01-01

    Station black out (SBO) of Fukushima Daiichi Nuclear Power Station Unit 1 would be concluded to be caused before 15:37 on March 11, 2011 because losses of emergency ac power A system was in 15:36 and ac losses of B system in 15:37 according to the data published by Tokyo Electric Power Co. (TEPCO) in May 10, 2013. Tsunami attacked the site of Fukushima Daiichi Nuclear Power Station passed through the position of wave amplitude meter installed at 1.5 km off the coast after 15:35 and it was also recognized tsunami arrived at the coast of Unit 4 sea side area around in 15:37 judging from a series of photographs taken from the south side of the site and general knowledge of wave propagation. From a series of photographs and witness testimony, tsunami didn't attack Fukushima Daiichi Nuclear Power Station uniformly and tsunami's arrival time at the site of Unit 1 would be far later than arrival time at the coast of Unit 4 sea side area, which suggested it would be around in 15:39. TEPCO insisted tsunami passed through 1.5 km off the coast around in 15:33 and clock of wave amplitude meter was incorrect, which might be wrong. Thus SBO of Fukushima Daiichi Nuclear Power Station Unit 1 occurred before tsunami's arrival at the site of Unit 1 and was not caused by tsunami. (T. Tanaka)

  16. Can we afford shutting down power stations?

    International Nuclear Information System (INIS)

    Hesse, David

    2015-01-01

    The author discusses and criticizes some popular beliefs on the profitability of nuclear power stations, on the fact that they are now too old to be exploited, and on the fact that nuclear energy is the most subsidised energy. As some European countries decided to phase out nuclear, he notices that the decrease of gas prices undermines the profitability of nuclear power stations in the USA and that new rules aimed at the reduction of CO 2 emissions result in high subsidies for renewable energies which are however handicapped by the grid ability to integrate all energies. He outlines that shutting down a nuclear power station costs a lot of money to the society, and denies the argument of non-profitability of these stations. He states that the issue of nuclear subsidies is in fact a matter of tax policy. He also states that these so-said old power stations take in fact advantage of numerous technical innovations for their equipment, components, technology and fuels which improve their efficiency, durability, performance and flexibility

    1983-01-01

    At the time of the construction of nuclear power stations, prior to their start of operation, the state of environmental radiation must be grasped. After the start of the power stations, based on those data, the system of environmental radiation monitoring is established. Along with the construction of Kashiwazaki-Kariwa Nuclear Power Station, The Tokyo Electric Power Co., Inc. jointly with Fujitsu Ltd. has developed a high-reliability, environmental radiation monitoring system, and adopted ''optical data highways'' using optical fiber cables for communication. It consists of a central monitoring station and 11 telemeter observation points, for collecting both radiation and meteorological data. The data sent to the central station through the highways are then outputted on a monitoring panel. They are analyzed with a central processor, and the results are printed out. (Mori, K.)

  19. Extension of life of nuclear power stations

    International Nuclear Information System (INIS)

    Takahashi, Hideaki

    1991-01-01

    At the time of designing nuclear power stations, as their service life, generally 40 years are taken, and the basic design specifications of machinery and equipment are determined. In USA where atomic energy has been developed, the new construction of nuclear power stations is cased for a while, however, if this situation continues as it is, since old power stations reach the service life of 40 years and are retired in near future, it is feared that the circumstance of the total amount of power generation becoming short will occur. As one of the countermeasures to this, the research on the extension of life of nuclear power stations has been carried out in many fields in USA, and it is expected that the application for extending the life for the power stations constructed in the initial period of development is submitted in 1991. The researches that have been carried out for solving the technical problems in this extension of life and the situation in Japan are reported. The NEC of USA decided that the operation period of nuclear power stations in USA, which is considered to be 40 years so far, can be extended up to the limit of 20 years. The background and circumstances of this problem in USA, Nuclear Plant Aging Research Program, Plant Life Extension Program and so on are reported. (K.I.)

    1981-01-01

    Kanto district and Shizuoka Prefecture are designated as ''Observation strengthening districts'', where the possibility of earthquake occurrence is high. Hamaoka Nuclear Power Station, Chubu Electric Power Co., Inc., is at the center of this district. Nuclear power stations are vulnerable to earthquakes, and if damages are caused by earthquakes in nuclear power plants, the most dreadful accidents may occur. The Chubu Electric Power Co. underestimates the possibility and scale of earthquakes and the estimate of damages, and has kept on talking that the rock bed of the power station site is strong, and there is not the fear of accidents. However the actual situation is totally different from this. The description about earthquakes and the rock bed in the application of the installation of No.3 plant was totally rewritten after two years safety examination, and the Ministry of International Trade and Industry approved the application in less than two weeks thereafter. The rock bed is geologically evaluated in this paper, and many doubtful points in the application are pointed out. In addition, there are eight active faults near the power station site. The aseismatic design of the Hamaoka Nuclear Power Station assumes the acceleration up to 400 gal, but it may not be enough. The Hamaoka Nuclear Power Station is intentionally neglected in the estimate of damages in Shizuoka Prefecture. (Kako, I.)

    Highlights: • Lighting systems are big energy consumers in underground metro stations. • An adaptive lighting system strategy is developed for underground stations. • Dimming controls are based on station occupancy levels and maintenance cycles. • The k-means clustering technique is used to identify stations’ occupancy patterns. • Savings were found to amount to 255.47 MW h in 2 years for a case study metro network. - Abstract: Lighting systems are usually one of the largest electrical end-uses in underground metro stations. Taking into account that budget restrictions in publicly owned companies hinder energy efficiency retrofit projects that require high initial investments, affordable energy saving strategies are needed. This paper presents a low-cost approach for reducing lighting electricity use in underground stations, without affecting passengers’ comfort or the metro operator’s service. For this purpose, an adaptive lighting strategy of dimming the illuminance levels of artificial light sources has been developed. Dimming controls are based on the occupancy of the station, and the preventive maintenance and cleaning cycles of the luminaires. The stations’ monthly occupancy patterns are defined through the k-means clustering technique. To illustrate its effectiveness, the method was applied to 115 underground stations of the Barcelona metro network. The results revealed overall electricity savings of 255.47 MW h on a biannual basis, which represents 36.22% of the stations’ baseline lighting consumption. Individual energy savings were found to range from 25 to 87.5 MW h/year in the stations of the Barcelona metro network, depending on the number and profile of station users. The research findings will undoubtedly be useful for the future energy efficiency project plans of worldwide metro operators and managers of other underground spaces.

    1987-01-01

    The display of diagnostic images is accomplished in the UCLA Pediatric Radiology Clinical Radiology Imaging System (CRIS) using 3 different types of digital viewing stations. These include a low resolution station with six 512 x 512 monitors, a high resolution station with three 1024 x 1024 monitors, and a very high resolution workstation with two 2048 x 2048 monitors. The display stations provide very basic image processing manipulations including zoom and scroll, contrast enhancement, and contrast reversal. The display stations are driven by a computer system which is dedicated for clinical use. During times when the clinical computer is unavailable (maintenance or system malfunction), the 512 x 512 workstation can be switched to operate from a research PACS system in the UCLA Image Processing Laboratory via a broadband communication network. Our initial clinical implementation involves digital viewing for pediatric radiology conferences. Presentation of inpatient cases use the six monitor 512 x 512 multiple viewing station. Later stages of the clinical implementation involve the use of higher resolution displays for the purpose of primary diagnosis from video displays

    Lack of charging stations has been a main obstacle to the promotion of electric vehicles. This paper studies deploying charging stations in traffic networks considering grid constraints to balance the charging demand and grid stability. First, we propose a statistical model for charging demand. Then we combine the charging demand model with power grid constraints and give the formulation of the charging station deployment problem. Finally, we propose a theoretical solution for the problem by transforming it to a Markov Decision Process.

Es frecuente que tanto los modelos como las prácticas de formación disocien la teoría y la práctica, el pensamiento de la acción. Aún en los currículos más actualizados de la región, los espacios destinados a la transmisión del conocimiento formalizado se fueron complejizando, mientras la «práctica» ha mantenido la concepción originaria que la identifica con el hacer, es decir, con la «aplicación» del saber aprendido en otras instancias. Sostenemos en este artículo que las dificultades o imposibilidades detectadas a la hora de enseñar en el presente se deben, fundamentalmente, a que maestros y profesores no han aprendido el oficio. Intentamos esbozar una propuesta formativa poniendo en valor los saberes de la experiencia, y avanzamos hacia modos de formar superadores de la dicotomía clásica entre teoría-práctica, saber-hacer, pensamiento y acción. Rasgos tales como la modelización y la vocación devenida en compromiso son recuperados y re-significados para la formación de docentes que sepan enseñar en los escenarios educativos actuales. 

  8. The local impacts of nuclear stations

    Gammon, K.M.

    1981-01-01

    The paper looks at the various non-radiological impacts of nuclear power stations on the environment which are grouped as ecological, amenity and socio-economic effects. The study and assessment of environment impacts are explained and comparisons made between those from nuclear and coal fired power stations. The prediction of future effects and judgement of their significance is difficult but is helped by the procedures evolved and by knowledge from the construction and operation of a large number of projects in physically different locations. Research is also needed into new issues and this must be recognised early. From experience of a number of nuclear stations it appears that the local impacts are acceptable provided care is taken.

    There are weighty reasons for and against the building of small nuclear power stations. Factors such as specific investment costs, opportunities for and areas of application, geographical conditions as well as those relating to infrastructure, security and availability play an important role in the planning, construction and running of a nuclear power station. For the usual large power stations, the comparatively low specific investment costs and a proven technology are favorable factors which minimize the investment risk. The article presents an overview of reasons for using small power stations and also considers the difficulties which would arise in practice. (orig.) [de

    The paper examines the features of the accommodation equipment designed for the candidate technology payloads of the Space Station, which include magnetic plasma thruster systems and a hypothetical advanced electromagnetic propulsion system utilizing high-temperature superconductivity materials. The review of the accommodation-equipment concepts supports the assumption that some propulsion technologies can be tested on the Space Station while being attached externally to the station's truss structure. For testing technologies with inherent operation or performance hazards, space platforms and smaller free-flyers coordinated with the Space Station can be used. Diagrams illustrating typical accommodation equipment configurations are included.

    The subject is covered in chapters, entitled: introduction (the background to Sizewell 'B'); policy options (Sizewell 'B'; a new coal-fired station; the no-new-station option; a PWR programme); economic framework (direct effects; financing; final macroeconomic effects); the construction phase (capital costs; direct effects; final effects; summary); the operating phase (a new power station as a replacement for older stations; the period of base-load operation; the later years of operation; summary); conclusions and policy recommendations. The first recommendation is that if a new power station is built it should be a coal-fired station rather than a PWR. The second recommendation is that if a new coal station is built there is a case for building it early, ahead of demand. (U.K.)

    Determination of electrical losses is one of the most important tasks for any enterprise dedicated to generation, transmission, transformation and/or distribution of electric energy. Any enterprise dedicated to these activities does continuously energy balances in order to estimate whole electrical losses of specific processes. However, it is necessary to classify the whole electrical losses into technical and non-technical losses. This paper presents a proposal for estimating technical and non-technical losses in an electrical power system. [Spanish] La determinacion de las perdidas de energia electrica es una de las labores mas importantes en cualquier empresa dedicada a la generacion, transmision, transformacion y/o distribucion de energia electrica. Es indudable que toda empresa dedicada a cualquiera de las actividades mencionadas anteriormente realiza periodicamente balances de energia que permiten estimar el valor de las perdidas totales de energia del proceso considerado. No obstante, para poder realizar un mejor analisis de la problematica de las perdidas de energia, es necesario separar el valor total de perdidas obtenido mediante un balance de energia, en perdidas tecnicas y perdidas no tecnicas. El presente trabajo presenta una propuesta para la estimacion de perdidas tecnicas y no tecnicas en un sistema electrico de potencia.

    1976-01-01

    For measurement of nuclear power station achievement against original purchase the usual gross output figures are of little value since the term loosely covers many different definitions. An authentically designed output figure has been established which relates to net design output plus house load at full load. Based on these figures both cumulative and moving annual load factors are measured, the latter measuring the achievement over the last year, thus showing trends with time. Calculations have been carried out for all nuclear stations in the Western World with 150 MW(e) gross design output and above. From these are shown: moving annual load factor indicating relative station achievements for all the plants; cumulative load factors from which return of investment can be calculated; average moving annual load factors for the four types of system Magnox, PWR, HWR, and BWR; and a relative comparison of achievement by country in a few cases.

    Full Text Available The last Hungarian repeat station survey was completed between October 2010 and February 2011. Declination, inclination and the total field were observed using one-axial DMI fluxgate magnetometer mounted on Zeiss20A theodolite and GSM 19 Overhauser magnetometer. The magnetic elements of the sites were reduced to the epoch of 2010.5 on the basis of the continuous recordings of Tihany Geophysical Observatory. In stations located far from the reference observatory, the observations were carried out in the morning and afternoon in order to decrease the effect of the distant temporal correction. To further increase the accuracy, on-site dIdD variometer has also been installed near the Aggtelek station, in the Baradla cave, during the survey of the easternmost sites. The paper presents the technical details and the results of our last campaign. The improvement of the accuracy of the temporal reduction by the use of the local variometer is also reported.

    1988-01-01

    The feasibility of using a solar water heater for NASA's Space Station is investigated using computer codes developed to model the Space Station configuration, orbit, and heating systems. Numerous orbit variations, system options, and geometries for the collector were analyzed. Results show that a solar water heater, which would provide 100 percent of the design heating load and would not impose a significant impact on the Space Station overall design is feasible. A heat pipe or pumped fluid radial plate collector of about 10-sq m, placed on top of the habitat module was found to be well suited for satisfying water demand of the Space Station. Due to the relatively small area required by a radial plate, a concentrator is unnecessary. The system would use only 7 to 10 percent as much electricity as an electric water-heating system.

    Extremely low-frequency (ELF) magnetic field (MF) measurements around and above three stand-alone 22/0.4-kV transformer stations have been performed. The low-voltage (LV) cables between the transformer and the LV switchgear were found to be the major source of strong ELF MFs of limited spatial extent. The strong fields measured above the transformer stations support the assessment method, to be used in future epidemiological studies, of classifying apartments located right above the transformer stations as highly exposed to MFs. The results of the MF measurements above the ground around the transformer stations provide a basis for the assessment of the option of implementing precautionary procedures.

    1982-01-01

    In the location of power sources hereafter, the location in natural landscape away from urban district tends to increase, accordingly, it is necessary to investigate beforehand the influence to surrounding scenery. However, the method of predicting and evaluating the effect on scenery has not yet been established, therefore, in this study, the basic concept on the investigation, forecast and evaluation of the scenery in power stations was clarified, and the establishment of the work procedure to evaluate the scenery and the effectiveness of the method of forecast and evaluation were examined. Also, the problems when power station facilities exert influence on scenery and the countermeasures to them were considered. Psychological experiment was carried out on the method of evaluation, and the structure and the regulating factors of scenery evaluation were clarified. Recently, good living environment is desired by public, and to the problems of fine environment regarding power stations, more attention is paid. The scenery problems of power stations are the protection of nature and the preservation of good living environment. Since this is an undeveloped field, many problems to be examined still remain.

This program evolved into Space Station Freedom, later identified as a component to facilitate a return of astronauts to the Moon, followed by the exploration of Mars. In March 1993 the Clinton Administration directed NASA to undertake an intense effort to redesign the space station at a substantial cost savings relative to Space Station Freedom. The Advisory Committee on the Redesign of the Space Station was established in March 1993 to provide independent assessment of the advantages and disadvantages of the redesign options. The results of the Committee's work is described. Discussion describes the mission that the Administration has articulated for the Space Station Program and the scientific and technical characteristics that a redesigned station must possess to fulfill those objectives. A description of recommended management, operations, and acquisition strategies for the redesigned program is provided. The Committee's assessment of the redesign options against five criteria are presented. The five criteria are technical capabilities, research capabilities, schedule, cost, and risk. A discussion of general mission risk is included.

  1. Smoke control of fires in subway stations

    We investigate the effectiveness of the smoke control scheme of the Gong-Guan subway station (GGSS), a typical subway station of the Taipei Rapid Transit System and whose mechanical control systems are also standard in modern subway station design. Three-dimensional smoke flow fields under various kinds of fires are computed by computational fluid dynamics techniques and the results are illustrated on various cross-sectional planes. Results indicate that the stack effect plays a deterministic role in smoke control when a fire occurs near the stairwell; under such circumstances, no mechanical smoke control is necessary. When a fire occurs in other places, such as at the end or the center of the platform, the current mechanical control schemes of GGSS are effective; namely, the smoke can be well controlled, either it is confined to a small region or is evacuated from the station, leaving the four exits free of smoke so that the passengers can escape through them. The effect of the platform edge door (PED) on smoke control is also investigated. With the PED, the effectiveness of the present smoke control system for fires occurring on the chassis of a train, a serious fire in the subway station, increases. We also propose an innovative smoke control scheme with a PED, which turns out to be much more efficient in evacuating smoke than that currently used. This study provides both valuable information for the design of passenger evacuation routes in fires as well as criteria for the design of a smoke control system for subway stations. (orig.)

  3. Nuclear power station achievement 1968-1980

    International Nuclear Information System (INIS)

    Howles, L.R.

    This report reviews and gives an analysis of the achievement of operating nuclear power stations in the Western world on three relevant bases: (1) both annual and cumulative achievement of all nuclear power stations at a particular time; (2) cumulative achievement of all nuclear power stations at the end of the first and subsequent years of their lives to show trends with age; (3) achievement based on refuelling period considerations. Nowhere in the report are any operating details ignored, omitted or eliminated in the method of analysis. Summarising the results of the reviews shows: an improvement with time from initial electricity generation on all bases; that initially, larger sizes of reactor/turbine operate less well than smaller sizes (except for PHWR's); that after an initial number of years, the largest size units operate as well as the intermediate and smaller sizes, or better in the PHWR case; that a 75 per cent cumulative load factor achievement in the middle years of a reactor/turbines life can be expected on the refuelling period considerations base; that at June 1980, 35 nuclear power stations achieved an annual load factor over 75 per cent; that the above achievement was possible despite the repercussions following the Three Mile Island 'accident' and the shutdowns in the USA for piping system seismic adequacy checks required by the Nuclear Regulatory Commission for five nuclear power stations; and that even when reactors/turbines are reaching towards the end of their design life, there is no rapid deterioration in their achievements.

    The rural industrial development literature is used to gain insights on the socioeconomic effects of nuclear power stations. Previous studies of large industrial facilities in small towns have important implications for attempts to understand and anticipate the impacts of nuclear stations. Even a cursory review of the nuclear development literature, however, reveals that industrialization research in rural sociology, economic geography and agricultural economics has been largely ignored

    In assessing the prospects of the NASA Space Station program, it is important to take account of the long term perspective embodied in the proposal; its international participants are seen as entering a complex web of developmental and operational interdependence of indefinite duration. It is noted to be rather unclear, however, to what extent this is contemplated by such potential partners as the ESA, which has its own program goals. These competing hopes for eventual autonomy in space station operations will have considerable economic, technological, and political consequences extending well into the next century.

  7. Electricity supplies in a French nuclear power station

    International Nuclear Information System (INIS)

    2011-01-01

    As the operation of a nuclear power station requires a power supply system enabling this operation as well as the installation safety, this document describes how such systems are designed in the different French nuclear power stations to meet the requirements during a normal operation (when the station produces electricity) or when it is stopped, but also to ensure power supply to equipment ensuring safety functions during an incident or an accident occurring on the installation. More precisely, these safety functions are provided by two independent systems in the French nuclear power stations. Their operation is briefly described. Two different types of nuclear reactors are addressed: pressurised water reactors (PWR) of second generation, EPR (or PWR of third generation)

    2013-10-01

    Preterm birth (PTB) is a growing public health problem potentially associated with ambient air pollution. Gasoline service stations can emit atmospheric pollutants, including volatile organic compounds potentially implicated in PTB. The objective of this study was to evaluate the relationship between residential proximity to gasoline service stations and PTB. Singleton live births on the Island of Montreal from 1994 to 2006 were obtained (n=267,478). Gasoline service station locations, presence of heavy-traffic roads, and neighborhood socioeconomic status (SES) were determined using a geographic information system. Multivariable logistic regression was used to analyze the association between PTB and residential proximity to gasoline service stations (50, 100, 150, 200, 250, and 500 m), accounting for maternal covariates, neighborhood SES, and heavy-traffic roads. For all distance categories beyond 50 m, presence of service stations was associated with a greater odds of PTB. Associations were robust to adjustment for maternal covariates for distance categories of 150 and 200 m but were nullified when adjusting for neighborhood SES. In analyses accounting for the number of service stations, the likelihood of PTB within 250 m was statistically significant in unadjusted models. Associations were, however, nullified in models accounting for maternal covariates or neighborhood SES. Our results suggest that there is no clear association between residential proximity to gasoline service stations in Montreal and PTB. Given the correlation between proximity of gasoline service stations and SES, it is difficult to delineate the role of these factors in PTB.

    2016-01-01

    Full Text Available El presente texto esboza la génesis y la evolución de la valoración moderna del paisaje en Cataluña, desde mediados del siglo XIX hasta el presente. Para entender mejor dicha evolución se han establecido cuatro etapas. La primera etapa, la que va de finales del siglo XIX hasta la Guerra Civil española, es de gran relevancia por su carácter seminal y por la estrecha conexión de la valoración cultural y simbólica del paisaje con los orígenes del pensamiento catalanista. La segunda se refiere al período franquista y en ella prácticamente desaparece cualquier interpretación del paisaje que se vincule al catalanismo político. La tercera etapa va de los primeros años de la democracia hasta la quiebra del consenso constitucional, a principios de los años 2000, y la cuarta etapa, la actual, está estrechamente relacionada con el cambio de paradigma impulsado por una sociedad civil que reclama, entre otros derechos, el de autodeterminación. El artículo muestra que, de una manera u otra, la valorización del paisaje en Cataluña ha tenido siempre una connotación identitaria y de reafirmación de una personalidad propia y diferenciada y ha sido siempre concebido como el resultado de un largo y lejano proceso de historicidad del territorio y de territorialización de la historia.

    2004-01-01

    I. Overview (a) Compressed Natural Gas - CNG:- Natural Gas, as an alternative fuel for vehicles, is supplied from the Natural Gas Distribution Network to the CNG fuelling stations to be compressed to 250 bars. It is then dispensed, to be stored on board of the vehicle at about 200 bars in a cylinder installed in the rear, under carriage, or on top of the vehicle. When the Natural Gas is required by the engine, it leaves the cylinder traveling through a high pressure pipe to a high pressure regulator, where the pressure is reduced close to atmospheric pressure, through a specially designed mixer, where it is properly mixed with air. The mixture then flows into the engine's combustion chamber, and is ignited to create the power required to drive the vehicle. (b) CNG Fuelling Stations General Description: as Supply and Metering The incoming gas supply and metering installation primarily depend on the pressure and flow demands of the gas compressor. Natural Gas Compressor In general, gas compressors for natural gas filling stations have relatively low flow rates

Significamos además su amistad con los «escritores eróticos» José Francés o Antonio de Hoyos y Vinent, como punto de partida del núcleo referencial de su obra, marcada por un simbolismo decadente, inspirado por la tradición centroeuropea y anglosajona, y aderezada con abundantes tópicos de españolidad.The aim of the following article is to provide an introduction about the works of Cuban painter Federico Beltrán. He may well represent a model in the transition between the symbolist painting tradition within the Spanish Art in the early 20th century towards the déco style which was later developed in the 1910's and 1920's. This model is referred to in the title itself, i.e.: Painter of Souls in the Modern Babilon. Since he befriended «erotic writers» José Francés and Antonio de Hoyos y Vinent, his style tended towards a decadent symbolism of central european and anglosaxon inspiration, presenting neverthelees abundant features of Spanish identity.

  6. Efficient placement of structural dynamics sensors on the space station

    Science.gov (United States)

    Lepanto, Janet A.; Shepard, G. Dudley

    1987-01-01

    System identification of the space station dynamic model will require flight data from a finite number of judiciously placed sensors on it. The placement of structural dynamics sensors on the space station is a particularly challenging problem because the station will not be deployed in a single mission. Given that the build-up sequence and the final configuration for the space station are currently undetermined, a procedure for sensor placement was developed using the assembly flights 1 to 7 of the rephased dual keel space station as an example. The procedure presented approaches the problem of placing the sensors from an engineering, as opposed to a mathematical, point of view. In addition to locating a finite number of sensors, the procedure addresses the issues of unobserved structural modes, dominant structural modes, and the trade-offs involved in sensor placement for space station. This procedure for sensor placement will be applied to revised, and potentially more detailed, finite element models of the space station configuration and assembly sequence.

    There is a general concern on the possible hazardous health effects of exposure to radiofrequency electromagnetic radiations (RFR) emitted from mobile phone base station antennas on the human nervous system. To identify the possible neurobehavioral deficits among inhabitants living nearby mobile phone base stations. A cross-sectional study was conducted on (85) inhabitants living nearby the first mobile phone station antenna in Menoufiya governorate, Egypt, 37 are living in a building under the station antenna while 48 opposite the station. A control group (80) participants were matched with the exposed for age, sex, occupation and educational level. All participants completed a structured questionnaire containing: personal, educational and medical histories; general and neurological examinations; neurobehavioral test battery (NBTB) [involving tests for visuomotor speed, problem solving, attention and memory]; in addition to Eysenck personality questionnaire (EPQ). The prevalence of neuropsychiatric complaints as headache (23.5%), memory changes (28.2%), dizziness (18.8%), tremors (9.4%), depressive symptoms (21.7%), and sleep disturbance (23.5%) were significantly higher among exposed inhabitants than controls: (10%), (5%), (5%), (0%), (8.8%) and (10%), respectively (Pstation exhibited a lower performance in the problem solving test (block design) than those under the station.

  9. New Seismic Monitoring Station at Mohawk Ridge, Valles Caldera

    Energy Technology Data Exchange (ETDEWEB)

    Roberts, Peter Morse [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2017-09-20

    Two new broadband digital seismic stations were installed in the Valles Caldera in 2011 and 2012. The first is located on the summit of Cerros del Abrigo (station code CDAB) and the second is located on the flanks of San Antonio Mountain (station code SAMT). Seismic monitoring stations in the caldera serve multiple purposes. These stations augment and expand the current coverage of the Los Alamos Seismic Network (LASN), which is operated to support seismic and volcanic hazards studies for LANL and northern New Mexico (Figure 1). They also provide unique continuous seismic data within the caldera that can be used for scientific studies of the caldera’s substructure and detection of very small seismic signals that may indicate changes in the current and evolving state of remnant magma that is known to exist beneath the caldera. Since the installation of CDAB and SAMT, several very small earthquakes have already been detected near San Antonio Mountain just west of SAMT (Figure 2). These are the first events to be seen in that area. Caldera stations also improve the detection and epicenter determination quality for larger local earthquakes on the Pajarito Fault System east of the Preserve and the Nacimiento Uplift to the west. These larger earthquakes are a concern to LANL Seismic Hazards assessments and seismic monitoring of the Los Alamos region, including the VCNP, is a DOE requirement. Currently the next closest seismic stations to the caldera are on Pipeline Road (PPR) just west of Los Alamos, and Peralta Ridge (PER) south of the caldera. There is no station coverage near the resurgent dome, Redondo Peak, in the center of the caldera. Filling this “hole” is the highest priority for the next new LASN station. We propose to install this station in 2018 on Mohawk Ridge just east of Redondito, in the same area already occupied by other scientific installations, such as the MCON flux tower operated by UNM.

  10. Benzene monitoring at CPPI service stations

    International Nuclear Information System (INIS)

    Davis, C.S.

    1996-01-01

    A study was conducted in which ambient airborne concentration levels of benzene were measured at a representative set of gasoline service stations in Toronto and Vancouver. Benzene is considered to be toxic under the Canadian Environmental Protection Act (CEPA). It is a component in gasoline (0.1 to 4.7 per cent by volume) and is present in vehicle evaporative and exhaust emissions. Measurements were made every 18 days at each station for one year. The objective of the study was to assess the ambient and employee exposure levels of benzene at service stations and to determine whether the levels were typical of those published in the literature. In a 1986 PACE (Petroleum Association for Conservation of the Canadian Environment) survey of exposure to gasoline hydrocarbon vapours at Canadian service stations, airborne benzene concentration data was inconsistent with similar ambient and personal exposure data in the international literature. It was concluded that both the mean ambient benzene concentration and the personal exposure level measurements in this study were generally lower than similar measurements made in other countries. The same observation was made with respect to ambient and personal exposure levels measured in this study vis-a-vis those measured during the PACE study conducted in 1985/86. . 31 refs., 24 tabs., 5 figs

    1989-01-01

    Over an operational lifetime of at least 30 yr, Space Station Freedom will encounter increased Space Station user requirements and advancing technologies. The Space Station electrical power system is designed with the flexibility to accommodate these emerging technologies and expert systems and is being designed with the necessary software hooks and hardware scars to accommodate increased growth demand. The electrical power system is planned to grow from the initial 75 kW up to 300 kW. The Phase 1 station will utilize photovoltaic arrays to produce the electrical power; however, for growth to 300 kW, solar dynamic power modules will be utilized. Pairs of 25 kW solar dynamic power modules will be added to the station to reach the power growth level. The addition of solar dynamic power in the growth phase places constraints in the initial Space Station systems such as guidance, navigation, and control, external thermal, truss structural stiffness, computational capabilities and storage, which must be planned-in, in order to facilitate the addition of the solar dynamic modules.

    Viewing requirements were identified early in the Space Station Freedom program for both direct viewing via windows and indirect viewing via cameras and closed-circuit television (CCTV). These requirements reside in NASA Program Definition and Requirements Document (PDRD), Section 3: Space Station Systems Requirements. Currently, analyses are addressing the feasibility of direct and indirect viewing. The goal of these analyses is to determine the optimum locations for the windows, cameras, and CCTV's in order to meet established requirements, to adequately support space station assembly, and to operate on-board equipment. PLAID, a three-dimensional computer graphics program developed at NASA JSC, was selected for use as the major tool in these analyses. PLAID provides the capability to simulate the assembly of the station as well as to examine operations as the station evolves. This program has been used successfully as a tool to analyze general viewing conditions for many Space Shuttle elements and can be used for virtually all Space Station components. Additionally, PLAID provides the ability to integrate an anthropometric scale-modeled human (representing a crew member) with interior and exterior architecture.

    A personal hygiene system is currently under development for Space Station application that will provide capabilities equivalent to those found on earth. This paper addresses the study approach for specifying both primary and contingency personal hygiene systems and provisions for specified growth. Topics covered are system definition and subsystem descriptions. Subsystem interfaces are explored to determine which concurrent NASA study efforts must be monitored during future design phases to stay up-to-date on critical Space Station parameters. A design concept for a three (3) compartment personal hygiene facility is included as a baseline for planned test and verification activities.

  20. Performance assessment of Point Lepreau Generating Station

    International Nuclear Information System (INIS)

    Alikhan, S.

    1991-01-01

    The Point Lepreau Generating Station, a 680 MWe CANDU unit, is located about 40 km southwest of the city of Saint John, New Brunswick, Canada. It was declared in-service on 1 February, 1983 and, since then, has demonstrated an average cross capacity factor of over 93% up to the end of 1990. This paper compared the performance of the station with other sister CANDU units and the Light Water Reactors world-wide using the following ten performance indicators, as applicable: - gross capacity factor; - fuel burn-up; - heavy water upkeep; - unplanned reactor trips while critical; - forced outage rate; - fuel handling performance; - derived emission of radioactive effluents to environment; - personnel radiation dose; - industrial safety; - low-level solid radioactive wastes. The paper examines various areas of station activities including management and organization, operations and maintenance, technical support, fuel handling and health physics in order to highlight some of the 'good practices' which are believed to have made a significant contribution towards achieving the demonstrated performance of Point Lepreau G.S. In addition, several areas of potential improvement are discussed in order to maintain and enhance, where practicable, the safety, reliability and economic performance of the station. In this context, a careful review of the operating experiences, both in-house and at other stations, and a judicious application of lessons learned plays a significant role. (author)
