    Costuma-se destacar os aspectos aparentemente positivos e as vantagens hipotéticas da concorrência e da competitividade entre empresas e também entre nações. Não se pode negar que a concorrência nos mercados tenha exercido uma função central e fundamental na gênese e na expansão do sistema de produção capitalista. Ela contribuiu para a geração e acumulação de riquezas materiais. Também estimulou e fortaleceu as aspirações de seus principais atores sociais, os empreendedores, de exigir uma organização política mais democrática em oposição ao regime feudal ou absolutista, em determinado período da história do mundo ocidental.

    Full Text Available Scepticism is a doctrine which holds the possibilities of knowledge to be limited. There are many types of scepticism (practical /theoretical, partial/total, moderate/ radical, etc. Scepticism as a philosophy began with Pyrrho of Elis (365–275 BC. The rediscovery of the sceptical texts during Renaissance affected the developmentof modern sceptical currents. In France philosophical statements of scepticism were offered by Michel de Montaigne (1533–1592. Blaise Pascal (1623–1662 great French mathematician, scientist, inventor an religious thinker was familiar with Montaigne sceptical ideas. Pascal refers to Montaigne as the most illustrious defender of scepticism. Blaise Pascal point of view is original. Whenever he insiststhat no proof is ever certain but simultaneously he adds that scepticism is untenable because we have reasons to believe.

  6. Gilson and Pascal

    Directory of Open Access Journals (Sweden)

    Richard J. Fafara

    2014-06-01

    Full Text Available Gilson’s early admiration for Pascal as a literary figure evolved into a deep appreciation of him as a Christian philosopher. Pascal showed Gilson that one could expect much more of philosophy than the idealism of René Descartes and Léon Brunschvicg so rampant in France during Gilson’s days as a student. Gilson’s existential Thomism, which highlighted Augustinian elements in St. Thomas’ thought, shares Pascal’s realism, his critique of rationalism, his situating philosophy within theology, and his view that the God of faith’s existence is largely independent of philosophical demonstrations that one gives of it. Despite many superficial dissimilarities, Gilson found Pascal’s scientific worldview continuous with the world of St. Thomas. Pascal, for Gilson, remained a model for the vocation of the Christian intellectual.

  8. PASCAL for engineers: A course including OMEGASOFT PASCAL for microcomputers

    International Nuclear Information System (INIS)

    Tausch, L.A.

    1985-01-01

    These are the notes of a PASCAL course for controls engineers at CERN. The course starts with 'Standard Pascal' and includes OMEGASOFT Pascal, a powerful extension of Pascal towards real-time and systems applications. It demonstrates how a language such as Pascal, with adequate extensions for systems programming and embedded microprocessor-driven systems, can substantially increase the productivity of programmers and the reliability of their products. Also enhanced will be the legibility of the programs and their maintainability, since programming in Pascal automatically leads to autodocumentation. Simple examples show how OMEGASOFT-PASCAL can be used for efficient programming of embedded systems for real-time data acquisition and control using the MC6809 microprocessor. (orig.)

    2014-11-01

    Full Text Available Il presente articolo si propone di indagare la versione pascaliana dell’agostinismo, sovente intesa dalla faziosa ermeneutica come anacronistico arroccamento nel medievalismo religioso, che, invece, proprio in virtù nella sua natura inattuale, e della matrice così straordinariamente inesauribile del pensiero agostiniano, si rivela profondamente moderna. Pascal, infatti, addolorato dalla vista di un esistente dibattentesi come una canna tra i venti delle configgenti istanze culturali e religiose del suo tempo, tra le rinnovate forme di eresia e l’imperante libertinismo, non vede in Agostino l’immagine aurea e pacifica di un Santo lontanissimo, non trova in lui il rifugio in un passato rassicurante, bensì di quegli recupera gli elementi drammatici, l’attenzione alla sofferta inquietudine dell’uomo dilaniato dalle dicotomiche alternative, disperatamente disperdentesi nelle malìe dell’esistere, cui entrambi i pensatori indicano il ritorno all’interioritas, a quel cuore non senza (Rragione. Tale ricerca ha messo in luce la riduttività dell’accostamento di Pascal ad Agostino solo per la via del religioso, perché, in fondo, è la problematicità e la problematizzazione del religioso che da Agostino giunge a Pascal e, confrontandosi con la crisi dei valori del 600, perverrà ad avere effetti disattesi.  This article aims to investigate Pascal version of augustinism, often considered from the partisan hermeneutic as anachronistic entrenchment in religious medievalism, which, precisely because of its outdated nature, and so extraordinarily inexhaustible kind of Augustine's thought is revealed to be profoundly modern.

    Full Text Available O presente artigo tem como objetivo analisar os avanços e os limites na análise da queda recente verificada na desigualdade no Brasil. É sabido que durante os anos 2000, a alteração verificada no Índice de Gini teve como efeitos a redução expressiva da pobreza extrema, com um crescimento de quase 20% na renda desses indivíduos. No entanto, apesar da melhora nos rendimentos - derivado da conjugação entre o aquecimento da economia nacional (com expansão do consumo, melhora dos preços relativos e maior atuação das políticas sociais e internacional - alguns trabalhos argumentam que a desigualdade deve ser vista por um prisma multidimensional. Nesse sentido, pretende-se sintetizar e analisar a literatura acerca do tema, demonstrando as suas limitações e propondo novos enfoques para o estudo da realidade brasileira.

  13. Os limites do desenvolvimento e do turismo

    Directory of Open Access Journals (Sweden)

    Menezes Teixeira Coriolano, Luzia Neide

    2003-01-01

    Full Text Available This paper is a historical analysis of the background and evolution of the concept of development and the limits to development, supported by links with economic science, thus pervading all social sciences. The assumptions of developmentalist theories, the so-called modernization theories, are shown and identified as traditional, conservative and consensual, thus differing from critical theories which adopt the assumptions of historical materialism. The paper examines those aspects of globalization which pertain to new approaches to development, whereby tourism becomes a link between the local and the global. The study explains how and why development is an unequal and joint process. Underdevelopment is a result of the structural adjustments which determine concentration of wealth and income, generating poverty as the ultimate expression of social inequality. It is shown that development only takes place when people benefit, when a human scale is reached, that tourism can both connect with concentrated economic growth and promote social development, otherwise known as local development

  19. Introduction to numerical computation in Pascal

    CERN Document Server

    Dew, P M

    1983-01-01

    Our intention in this book is to cover the core material in numerical analysis normally taught to students on degree courses in computer science. The main emphasis is placed on the use of analysis and programming techniques to produce well-designed, reliable mathematical software. The treatment should be of interest also to students of mathematics, science and engineering who wish to learn how to write good programs for mathematical computations. The reader is assumed to have some acquaintance with Pascal programming. Aspects of Pascal particularly relevant to numerical computation are revised and developed in the first chapter. Although Pascal has some drawbacks for serious numerical work (for example, only one precision for real numbers), the language has major compensating advantages: it is a widely used teaching language that will be familiar to many students and it encourages the writing of clear, well­ structured programs. By careful use of structure and documentation, we have produced codes that we be...

  20. HDM/PASCAL Verification System User's Manual

    Science.gov (United States)

    Hare, D.

    1983-01-01

    The HDM/Pascal verification system is a tool for proving the correctness of programs written in PASCAL and specified in the Hierarchical Development Methodology (HDM). This document assumes an understanding of PASCAL, HDM, program verification, and the STP system. The steps toward verification which this tool provides are parsing programs and specifications, checking the static semantics, and generating verification conditions. Some support functions are provided such as maintaining a data base, status management, and editing. The system runs under the TOPS-20 and TENEX operating systems and is written in INTERLISP. However, no knowledge is assumed of these operating systems or of INTERLISP. The system requires three executable files, HDMVCG, PARSE, and STP. Optionally, the editor EMACS should be on the system in order for the editor to work. The file HDMVCG is invoked to run the system. The files PARSE and STP are used as lower forks to perform the functions of parsing and proving.

    Full Text Available Uma abordagem lexográfica do amor próprio nos escritos de Pascal: carta (1651 sobre a morte de seu pai, frag. La 978 e nove ocorrências nos Pensamentos. A partir dos diferentes "amores-próprios" enumerados pela tradição, o amor-próprio natural de Adão, anterior à Queda, que para Tomás de Aquino é indiferente, é identificado por Jansenius como pervertido em concupiscência. Em sua Apologia, Pascal segue a linha jansenista de um modo tão radical que os teólogos de Port-Royal julgaram preciso mitigar seus sentimentos a ponto de contradizê-lo, como fez Nicole, que descreveu o amor-próprio como um substituto hipocrítico do comportamento virtuoso.A lexicological approach of self-love in Pascal’s writings: letter (1651 about his father’s death, frag. La 978 and nine occurrences in the Pensées. From the different "self-loves" enumerated by the tradition, Adam’s natural self-love, before the Fall, which is indifferent for Thomas Aquinas, is identified by Jansenius as perverted into concupiscentia. In his Apology, Pascal follows the Jansenist line, in such a radical way that the Port-Royal theologians found necessary to mitigate his feelings, up to contradict him, like Nicole did, who described self-love as a hypocritical substitute to virtuous behaviour.

  3. Coefficients Calculation in Pascal Approximation for Passive Filter Design

    Directory of Open Access Journals (Sweden)

    George B. Kasapoglu

    2018-02-01

    Full Text Available The recently modified Pascal function is further exploited in this paper in the design of passive analog filters. The Pascal approximation has non-equiripple magnitude, in contrast of the most well-known approximations, such as the Chebyshev approximation. A novelty of this work is the introduction of a precise method that calculates the coefficients of the Pascal function. Two examples are presented for the passive design to illustrate the advantages and the disadvantages of the Pascal approximation. Moreover, the values of the passive elements can be taken from tables, which are created to define the normalized values of these elements for the Pascal approximation, as Zverev had done for the Chebyshev, Elliptic, and other approximations. Although Pascal approximation can be implemented to both passive and active filter designs, a passive filter design is addressed in this paper, and the benefits and shortcomings of Pascal approximation are presented and discussed.

    Description of program or function: LRSYS is a complete LR(1) parser generator system written entirely in a portable subset of Pascal. The system, LRSYS, includes a grammar analyzer program (LR) which reads a context-free (BNF) grammar as input and produces LR(1) parsing tables as output, a lexical analyzer generator (LEX) which reads regular expressions created by the REG process as input and produces lexical tables as output, and various parser skeletons that get merged with the tables to produce complete parsers (SMAKE). Current parser skeletons include Pascal, FORTRAN 77, and C. In addition, the CRAY1, DEC VAX11 version contains LRLTRAN and CFT- FORTRAN 77 skeletons. Other language skeletons can easily be added to the system. LRSYS is based on the LR program (NESC Abstract 822)

    Blaise Pascal was a true Renaissance man being well versed in science, physics, religion, philosophy, and especially mathematics. He had a knack for simplifying complex problems into mathematical formulae. He had well-formed opinions about the scientific issues of his day, in particular about risk. There is little doubt that were he alive today, he would have opinions useful to this society. This paper addresses what he thought then as a foundation for what he would have thought now.

  11. GENPLOT: A formula-based Pascal program for data manipulation and plotting

    Science.gov (United States)

    Kramer, Matthew J.

    Geochemical processes involving alteration, differentiation, fractionation, or migration of elements may be elucidated by a number of discrimination or variation diagrams (e.g., AFM, Harker, Pearce, and many others). The construction of these diagrams involves arithmetic combination of selective elements (involving major, minor, or trace elements). GENPLOT utilizes a formula-based algorithm (an expression parser) which enables the program to manipulate multiparameter databases and plot XY, ternary, tetrahedron, and REE type plots without needing to change either the source code or rearranging databases. Formulae may be any quadratic expression whose variables are the column headings of the data matrix. A full-screen editor with limited equations and arithmetic functions (spreadsheet) has been incorporated into the program to aid data entry and editing. Data are stored as ASCII files to facilitate interchange of data between other programs and computers. GENPLOT was developed in Turbo Pascal for the IBM and compatible computers but also is available in Apple Pascal for the Apple Ile and Ill. Because the source code is too extensive to list here (about 5200 lines of Pascal code), the expression parsing routine, which is central to GENPLOT's flexibility is incorporated into a smaller demonstration program named SOLVE. The following paper includes a discussion on how the expression parser works and a detailed description of GENPLOT's capabilities.

    Ana Paula Paes de Paula

    Full Text Available O objetivo deste artigo é questionar o pluralismo do movimento critical management studies (CMS, apontar os limites do pós-estruturalismo como epistemologia crítica, denunciar os riscos de uma crítica alinhada com o "gerencialismo engajado" e apontar caminhos para o debate sobre a teoria e a prática no movimento crítico. Para isso, definimos as principais características do pós-estruturalismo, questionando seu caráter crítico, e problematizamos a questão do pluralismo no movimento CMS. Em seguida, analisamos como alguns dos representantes deste movimento defendem o "gerencialismo engajado" através de uma performatividade crítica, fazendo um uso inadequado de algumas formulações pós-estruturalistas. Discutimos então os caminhos para a prática na crítica, resgatando o conceito de práxis e afirmando a importância da educação como forma de despertar consciências e reconstituir o ativismo social e político. Concluímos destacando que o pós-estruturalismo deveria ser resgatado com maior seriedade, de modo a se constituir um novo movimento teórico para abrigar suas contribuições, preservando o caráter crítico.

    Full Text Available Após uma breve introdução histórica e um esclarecimento terminológico, o quadro psicopatológico clássico das organizações-limite, descrito por Kernberg, está resumido tanto na sua dimensão clínica, estrutural, como genética. As diferentes correntes psicodinâmicas contemporâneas são lembradas; em seguida, os principais trabalhos psicanalíticos de língua francesa são apresentados, tanto a respeito dos adultos (Bergeret, Green como das crianças e adolescentes (Diatkine, Mises, Jeammet. A especificidade teórica da psicanálise francesa, ligada tanto ao impulso como às relações de objeto, à intra-psíquica como ao intra-subjetivo, é destacada. Uma síntese atual (Brusset, Chabert é proposta baseada em três problemáticas principais: a patologia do transtorno borderline e a falta de interioridade, a angústia da perda do objeto, as particularidades do conflito edipiano e o masoquismo. O peso das modificações psicossociais e culturais contemporâneas sobre as mudanças da psicopatologia é aqui evocada.

  18. La vrai morale se moque de la morale: questões éticas em Pascal

    Full Text Available Em Pascal encontramos um duplo registro da questão moral: por um lado, o autor dos Pensées dirige uma dura crítica aos ideais morais da filosofia, especialmente aos do estoicismo; por outro, ele afirma uma "verdadeira moral" que "zomba da moral". A análise desse duplo registro será feita a partir de quatro contextos encontrados nos Pensamentos: 1- O contexto epistemológico da diferença entre espírito geométrico e espírito de finesse, ao qual se remetem os termos correlatos "moral do espírito" e "moral do julgamento"; 2- O contexto antropológico da "desproporção do homem" e da virtude como meio-termo; 3- O contexto antropológico - teológico da miséria e da grandeza do homem 4- O contexto metafísico-teológico da teoria das "três ordens de coisas". A "verdadeira moral" constitui-se, afinal, por dois movimentos: no primeiro, a moral pascaliana é simplesmente naturalista e compartilha do espírito mecanicista do seu século. Em seu segundo movimento, ela é teológica e constitui-se essencialmente como uma hermenêutica do desejo.We find in Pascal a double approach to the moral issue. On the one hand the author of the Pensées strongly criticizes the moral ideals of philosophy, in particular those of Stoicism but, on the other, he claims that there is a "true morals" which "mocks of morals". We here analyze this double approach from the point of view of four contexts exhibited in the Pensées: 1- The epistemological context that distinguishes the "esprit de géométrie" and the "esprit de finesse" which points, respectively, to a "moral of the ' esprit'" and to a "moral of judgment". 2- The anthropological context of the "disproportion of men" and of virtue as mean 3- The anthropological-theological context of the misery and greatness of man. 4- The metaphysical-theological context of the theory of the "three orders of things". The "true morals" is construed in two movements. In the first, Pascal's morals is naturalistic and

  19. Software tools to aid Pascal and Ada program design

    Energy Technology Data Exchange (ETDEWEB)

    Jankowitz, H.T.

    1987-01-01

    This thesis describes a software tool which analyses the style and structure of Pascal and Ada programs by ensuring that some minimum design requirements are fulfilled. The tool is used in much the same way as a compiler is used to teach students the syntax of a language, only in this case issues related to the design and structure of the program are of paramount importance. The tool operates by analyzing the design and structure of a syntactically correct program, automatically generating a report detailing changes that need to be made in order to ensure that the program is structurally sound. The author discusses how the model gradually evolved from a plagiarism detection system which extracted several measurable characteristics in a program to a model that analyzed the style of Pascal programs. In order to incorporate more-sophistical concepts like data abstraction, information hiding and data protection, this model was then extended to analyze the composition of Ada programs. The Ada model takes full advantage of facilities offered in the language and by using this tool the standard and quality of written programs is raised whilst the fundamental principles of program design are grasped through a process of self-tuition.

    1982-01-01

    A high level language for the Massively Parallel Processor (MPP) was designed. This language, called Parallel Pascal, is described in detail. A description of the language design, a description of the intermediate language, Parallel P-Code, and details for the MPP implementation are included. Formal descriptions of Parallel Pascal and Parallel P-Code are given. A compiler was developed which converts programs in Parallel Pascal into the intermediate Parallel P-Code language. The code generator to complete the compiler for the MPP is being developed independently. A Parallel Pascal to Pascal translator was also developed. The architecture design for a VLSI version of the MPP was completed with a description of fault tolerant interconnection networks. The memory arrangement aspects of the MPP are discussed and a survey of other high level languages is given.

  3. Os limites do funcionamento interpretante do aparato psíquico The limits of the interpretative function of the psychic apparatus

    2001-06-01

    Full Text Available De início, o artigo identifica uma função interpretante na conceituação do aparato psíquico realizada por Freud. Esta função encontra-se melhor explicada no desenvolvimento da "Interpretação dos Sonhos", os quais operam, por sua vez, a mesma função interpretante. Em seguida, argumenta que, desde 1900, Freud conceitua um limite e uma exceção no funcionamento da interpretação nos sonhos, localizando-os, no entanto, em duas tópicas diferentes. A visão de Lacan vem introduzir uma nova inteligibilidade à interpretação ao ressituar os seus limites no lugar mesmo do funcionamento do aparato. Esse instante de impossibilidade, presente em toda interpretação, é examinado tendo em vista a sua conseqüência clínica de apontar para a necessidade do ato analítico, como a intervenção que faz advir o sujeito da análise.Firstly the article identifies an interpretative function in the conceptualization of the psychic apparatus, by Freud. This function is best explained in "The Interpretation of Dreams". These are understood to operate in their turn the same interpretative function as the apparatus. Secondly it is argued that since 1900 Freud conceptualizes a limit and an exception in the function of dream-interpretation. However, he localizes these limits in two different explanations of the apparatus. Lacan introduces a new way of understanding the matter by affirming that the limits are comprehended in one and the same explanation of the functioning of the apparatus. A moment of impossibility which is present in all interpretations is examined in view of its clinical consequences, since it points to a necessary analytical act. This is the intervention that makes it possible for the analytical subject to exist.

    Edlaine de Campos Gomes

    2008-01-01

    Full Text Available Este artigo analisa a polêmica em torno da determinação dos limites da vida, a partir do pressuposto de que a demarcação das fronteiras entre vida e morte envolve questões culturais, sociais, religiosas e políticas referentes à gestão da pessoa. Debates acerca do aborto e da eutanásia evidenciam concepções morais sobre os direitos individuais que, por sua vez, são passíveis de normatização em cada contexto. Tais temas revelam para além da criação e do desenvolvimento de novas tecnologias médicas, direcionadas à reprodução assistida, medicina fetal e manutenção artificial da vida, seja de prematuros ou de doentes fora de possibilidades de cura valores e posicionamentos, muitas vezes contrastivos. A partir de levantamento de projetos de lei apresentados no âmbito legislativo brasileiro, constatou-se a presença de discursos opostos, oriundos da religião e de defensores da autonomia individual, o que ilustra os dilemas contemporâneos sobre os limites da vida.This article analyzes the controversy surrounding what can be established as the limit of life, from the presumption that the frontier marks between life and death involve cultural, social, religious and political issues referred to personhood management. Debates about abortion and euthanasia make it clear that moral concepts on individual rights can be standardized in each context. These themes reveal beyond new medical technology creation and development, focused on assisted fertilization, fetal medicine and maintaining life artificially, either for premature babies or patients without possibilities of cure values and viewpoints, often opposed. From the survey of law projects, presented within Brazilian legislative field, opposite positions were revealed, from religion and defenders of individual autonomy, which illustrates the contemporary dilemmas on the limits of life.

    Full Text Available O objetivo primário deste trabalho é identificar os limites da influência das empresas multinacionais (EMNs em processos multilaterais de negociação. A efetividade da defesa de seus interesses depende, basicamente, da confluência dos interesses entre os Estados e as empresas e depende da vulnerabilidade dos Estados em relação às atividades das empresas, bem como da capacidade relativa das coalizões que as empresas buscam influenciar. Em seguida, é reconhecida a limitação do poder de influência das EMNs através de uma extensão do modelo Frieden-Rogowsky, onde se propõe que os setores prejudicados pelo processo de internacionalização tendem, tanto em nível nacional quanto em nível transnacional, a se opor a ações políticas das EMNs. Finalmente, apresenta-se um estudo de caso sobre o Protocolo de Cartagena de Biosegurança, instrumento complementar à Convenção de Biodiversidade (CBD, que regulamenta os organismos geneticamente modificados (OGMs. Uma importante conclusão do trabalho é explicar as circunstâncias em que as EMNs operam como negociadoras, através de sua influência e da utilização de poder estrutural e brando, buscando formar coalizões transnacionais e incentivar a formação de coalizões entre Estados que defendam os seus interesses em contextos intergovernamentais.The main objective of this work is to identify the limits of the influence of multinational companies (MNCs in multilateral negotiation processes.

    As a part of the aging and structural integrity research for LWR components, a new PFM (Probabilistic Fracture Mechanics) code PASCAL (PFM Analysis of Structural Components in Aging LWR) has been developed since FY1996. This code evaluates the failure probability of an aged reactor pressure vessel subjected to transient loading such as PTS (Pressurized Thermal Shock). The development of the code has been aimed to improve the accuracy and reliability of analysis by introducing new analysis methodologies and algorithms considering the recent development in the fracture mechanics methodologies and computer performance. The code has some new functions in optimized sampling and cell dividing procedure in stratified Monte Carlo simulation, elastic-plastic fracture criterion of R6 method, extension analysis models in semi-elliptical crack, evaluation of effect of thermal annealing and etc. In addition, an input data generator of temperature and stress distribution time histories was also prepared in the code. Functions and performance of the code have been confirmed based on the verification analyses and some case studies on the influence parameters. The present phase of the development will be completed in FY2000. Thus this report provides the user's manual and theoretical background of the code. (author)

  11. Philology and Music in the Work of Pascal Quignard

    Directory of Open Access Journals (Sweden)

    John Hamilton

    2009-01-01

    Full Text Available The persistent association of philology and music in the work of Pascal Quignard is mediated through various modalities of silence. Throughout Quignard’s novels, essays and treatises, musical sensibility and philological obsession work to silence the all-too-loud, abstracting processes of communication, representation, narration, or discourse. Upon sketching out the general terms and definitions that Quignard employs across his writing career, the essay turns to two especially illustrative examples: Quignard’s reading of Lucretius and his reflections on Plato’s discussion of misology. Misology, denoting a deep mistrust of words, ends up serving as a synonym for philology itself; it is a hatred of words—that is, a hatred of the way words are subsumed into logical discourse—that presents itself as the only true love of words, a love that respects a word’s resistance to any system, a philology that attends to a word’s relation to silence and thereby to the music of singularity.

  12. Comparison of PASCAL and FORTRAN for solving problems in the physical sciences

    Watson, V. R.

    1981-01-01

    The paper compares PASCAL and FORTRAN for problem solving in the physical sciences, due to requests NASA has received to make PASCAL available on the Numerical Aerodynamic Simulator (scheduled to be operational in 1986). PASCAL disadvantages include the lack of scientific utility procedures equivalent to the IBM scientific subroutine package or the IMSL package which are available in FORTRAN. Advantages include a well-organized, easy to read and maintain writing code, range checking to prevent errors, and a broad selection of data types. It is concluded that FORTRAN may be the better language, although ADA (patterned after PASCAL) may surpass FORTRAN due to its ability to add complex and vector math, and the specify the precision and range of variables.

    1992-07-01

    In wrestling with the problem of the existence of God, Blaise Pascal proposed a line of reasoning at once prudent and self-interested. His reasoning is instructive to policy makers now facing the prospect of global warming. In contrast to some economists and the findings of the Adaptation Panel of the National Academy of Sciences, Pascal's logic would lead us to minimize greenhouse gas emissions for reasons of both prudence and self-interest. 7 refs.

MÉTODOS: Se estudiaron 74 pacientes (140 ojos, mayores de 21 años, con miopía estable (de -1 dioptrías a -10 dioptrías, defecto cilíndrico inferior a -3 dioptrías y espesor corneal central menor de 480 micras. Los pacientes fueron intervenidos con excímer láser (técnica de LASIK, en el Servicio de Cirugía Refractiva del Instituto Cubano de Oftalmología "Ramón Pando Ferrer", de diciembre de 2006 a marzo de 2007, con un seguimiento posoperatorio de 1 año, aunque se estimó el comportamiento de las variables al mes de la cirugía. RESULTADOS: Predominó discretamente el sexo femenino, el grupo de edad de 21 a 39 años constituyó el 81 %, y la miopía moderada en 74 ojos el 52,8 %. El valor de la presión intraocular con tonómetro de contorno dinámico superó al obtenido con el de Goldmann en 2 mm Hg en el preoperatorio y en 3,7 mm Hg en el posoperatorio. Se correlacionó la variación del espesor corneal posterior al LASIK y la presión intraocular según el tonómetro utlizado. CONCLUSIONES: Los valores de la presión con el tonómetro de Pascal son más confiables que los obtenidos con el tonómetro de aplanación de Goldmann, cuando el espesor corneal central se aleja de lo estipulado como normal.OBJECTIVES: To compare the intraocular pressure figures obtained with Goldman applanation tonometer and with Pascal dynamic contour tonometer, as well as the central corneal thickness variation before and after the refractive surgery with LASIK, and to set the relationship between both tonometers.

Tratou-se do estudo da publicação de Histórias Extraordinárias (1978; 2003 com tradução de Breno Silveira e de tradução e adaptação, com o mesmo título, de Clarice Lispector. Observamos que o conjunto de contos da obra original diferiu do conteúdo dos volumes produzidos em português, o qual apresenta título bem diverso do original. Por meio de uma análise comparativa, envolvendo o original e as duas traduções, investigamos o que nesse contexto foi considerado o original. Além disso, um dos volumes em português já se coloca como adaptação, o que, do ponto de vista investigativo levantou outra questão a ser estudada: se a própria tradução não reproduz o original, então qual seria o limite entre tradução e adaptação? Procuramos responder a essa questão tomando a idéia de que todo texto traduzido já é uma reescrita e transforma o original (Lefevere 1992, Amorim 2006. A reflexão sobre o limite entre tradução e adaptação na contemporaneidade traz para o debate o questionamento sobre o próprio conceito de original e de tradução (Paz 1990; Derrida 1982, Ferreira 2006 e 2007 e sobre os condicionantes da constituição de imagens nas culturas alvo (Rodrigues 2001, Amorim 2006; conceitos em que nos concentramos para responder a questão aqui proposta.

    Full Text Available Resumo: Os Estados contemporâneos caracterizam-se por um acentuado pluralismo étnico, racial e religioso, o que vem se acentuando nos últimos anos, em razão do fenômeno da migração e do refúgio humanitário. Essa situação tem levado grupos de migrantes, refugiados e nacionais marginalizados a encaminhar demandas por reconhecimento, respeito e promoção de sua singularidade cultural, impondo aos governos o incontornável desafio de delimitar o espaço legítimo das manifestações divergentes, bem como da extensão da representação política e do autogoverno desses grupos populacionais. Apesar de a política da diferença contrapor-se, até certo ponto, aos postulados liberais que orientam os Estados contemporâneos, as demandas por reconhecimento provavelmente continuarão a ocorrer. Nesse processo, o Direito Internacional dos Direitos Humanos constitui um limite infranqueável às expressões culturais divergentes, principalmente no que se refere às migrações, imigrações e refúgios. Neste estudo, o método de abordagem é o dialético, e a técnica de pesquisa é a bibliográfica. A título de considerações finais, o reconhecimento parcial, mas progressivo, vem sendo, mundo afora, a criação de inúmeros programas de valorização das minorias culturais, a instituição de ações afirmativas compensatórias, a atribuição de autonomia, o autogoverno a certos grupos, a consideração de seus costumes e tradições no momento de aplicação de leis gerais, entre tantas outras medidas Estatais.

    2005-01-01

    A - Description of program or function: PASCAL (PFM analysis of Structural Components in Aging LWR) is a PFM (Probabilistic Fracture Mechanics) code for evaluating the failure probability of aged pressure components. PASCAL has been developed as a part of the JAERI's research program on aging and structural integrity of LWR components, in order to respond to the increasing need of the probabilistic methodology in the regulation and inspection of nuclear components with the objective to provide a rational tool for the evaluation of the reliability and integrity of structural components. In order to improve the accuracy and reliability of the analysis code, some new fracture mechanics models or computational techniques are introduced considering the recent progress in the state of the art and performance of PC. Thus some new analysis models and original methodologies were introduced in PASCAL such as the elastic-plastic fracture criterion based on R6 method, a new crack extension model of semi-elliptical crack evaluation and so on. Moreover a function to evaluate the effect of embrittlement recovery by annealing of irradiated RPV is also introduced in the code based on the USNRC R.G. 1.162(1996). The code has been verified through various failure analysis results and international PTS round robin analysis ICAS which had been organized by the Principal Working Group 3 of OECD/NEA/CSNI. In order to attain a high usability, PASCAL Ver.1 with GUI provides an exclusive FEM pre-processor Pre-PASCAL for generating the input load transient data, a GUI system for generating the input data for PASCAL main processor of main solver and post-processor for output data. - Pre-PASCAL: Pre-PASCAL is an exclusive 3-D FEM pre-processor for generating the input transient data provided with 3 RPV mesh models and two simple specimen mesh models, i.e. CT and CCP. Almost the same input data format with that of PASCAL main processor is used. Output data of temperature and stress distribution

On longer, 150 base paired end noisy Cambridge Epigenetix's data, a Pascal GTX 1080 processes about 10000 strings per second, comparable with twin nVidia Tesla K40.

    A computer program has been written to provide an interface between the HP Series 200 desktop computers, operating under HP Standard Pascal 3.0, and the HP2250 Data Acquisition and Control System. Pascal 3.0 for the HP9000 desktop computer gives a number of procedures for handling bus communication at various levels. It is necessary, however, to reach the lowest possible level in Pascal to handle the bus protocols required by the HP2250. This makes programming extremely complex since these protocols are not documented. The program described solves those problems and allows the user to immediately program, simply and efficiently, any measurement and control language (MCL/50) application with a few procedure calls. The complete set of procedures is available on a 5 1/4 inch diskette from Cosmic. Included in this group of procedures is an Exerciser which allows the user to exercise his HP2250 interactively. The exerciser operates in a fashion similar to the Series 200 operating system programs, but is adapted to the requirements of the HP2250. The programs on the diskette and the user's manual assume the user is acquainted with both the MCL/50 programming language and HP Standard Pascal 3.0 for the HP series 200 desktop computers.

    Full Text Available Este artigo apresenta algumas reflexões acerca das possibilidades e limites da racionalização e flexibilização do processo de gestão nos serviços de saúde sob a perspectiva econômica, focalizando a introdução de mecanismos e instrumentos centrados na responsabilização econômica e organizacional dos recursos e a participação da enfermagem nestes processos. Discutese a adoção de um sistema de controle econômico que coordene os interesses dos diversos sujeitos envolvidos; privilegie os resultados dos processos e melhore a combinação econômica dos recursos. Sob essa perspectiva, dois conceitos são considerados relevantes na elaboração do orçamento do Sen/iço de Enfermagem: a controlabilidade dos recursos e a negociação nos processos de alocação e utilização destes. A operacionalização desses conceitos no âmbito da (reorganização dos serviços de saúde, mais especificamente, na área de enfermagem cria novas possibilidades de participação nos processos de produção de serviços, assegurando maior transparência nos processos decisórios e reconfigurando novas modalidades de gestão para os serviços de enfermagem.

    2006-01-01

    Full Text Available O presente trabalho mostra os principais problemas enfrentados por empreendimentos de economia solidária quando entram no mercado e precisam concorrer com outras empresas. No sistema capitalista predominam empresas privadas e estas, ao enfrentarem concorrência, precisam reduzir preços e custos, ou ainda encontrar meios para eliminar a concorrência e manter-se ou estabelecer-se como monopolista. Tendem, então, a concentrar e aumentar a composição orgânica do capital, de modo que a produtividade aumenta e pode-se, então, dispensar trabalhadores. E os empreendimentos de economia solidária, como poderão comportar-se diante dessa situação? Essas cooperativas, associações e empresas autogestionárias, pautadas em princípios de associação livre e voluntária por parte dos trabalhadores, gestão coletiva das decisões e dos resultados e propriedade coletiva dos meios de produção, geralmente sofrem de crônica falta de recursos, além da dificuldade de acesso ao crédito. Isso faz com que tais empreendimentos iniciem suas atividades com desvantagem em relação aos demais, e a mortalidade dessas empresas parece inevitável. Porém, se esses empreendimentos conseguem superar a falta de recursos, como poderão aumentar produtividade e reduzir custos sem que para isso seja necessário dispensar trabalhadores? Necessita-se saber, portanto, se cooperativas conseguem sustentarse como tais, mantendo seus princípios e sua forma de gestão dentro do capitalismo, inovar tecnologia e conseguir concorrer com outras empresas sem que os princípios cooperativistas sejam feridos.

  6. Pascal (Yang Hui) triangles and power laws in the logistic map

    2015-01-01

    We point out the joint occurrence of Pascal triangle patterns and power-law scaling in the standard logistic map, or more generally, in unimodal maps. It is known that these features are present in its two types of bifurcation cascades: period and chaotic-band doubling of attractors. Approximate Pascal triangles are exhibited by the sets of lengths of supercycle diameters and by the sets of widths of opening bands. Additionally, power-law scaling manifests along periodic attractor supercycle positions and chaotic band splitting points. Consequently, the attractor at the mutual accumulation point of the doubling cascades, the onset of chaos, displays both Gaussian and power-law distributions. Their combined existence implies both ordinary and exceptional statistical-mechanical descriptions of dynamical properties. (paper)

    Full Text Available RESUMO Este texto tem como objetivo oferecer uma releitura do conceito de autoria de Michel Foucault, definido e comentado a partir de três textos fundamentais: A Arqueologia do Saber, O que é um autor? e A Ordem do Discurso. A hipótese é de que a autoria pode ser lida como um dispositivo – o dispositivo da autoria ou autoral – e que, dessa perspectiva, pode ser problematizado a partir do conceito de resistência e da preocupação ética do chamado “último Foucault”. Para defender tal hipótese, recorre-se inicialmente à descrição do conceito do dispositivo e do conceito de autoria, na arqueogenealogia e segundo alguns comentadores. Depois, traça-se uma discussão entre o dispositivo da autoria e as possibilidades de resistência e de criação subjetiva, presentes em conceitos como epimeleia heautou, crítica ou dessubjetivação. Por fim, sugere-se que o dispositivo da autoria pode ser lido ainda foucaultianamente, desde que segundo a ordem de uma política e de uma luta agonística entre os viventes e os dispositivos.

    As a part of research on the material degradation and structural integrity assessment for aged LWR components, a PFM (Probabilistic Fracture Mechanics) analysis code PASCAL-SP (PFM Analysis of Structural Components in Aging LWR - Stress Corrosion Cracking at Welded Joints of Piping) has been developed. This code evaluates the failure probabilities at welded joints of aged piping by a Monte Carlo method. PASCAL-SP treats stress corrosion cracking (SCC) and fatigue crack growth in piping, according to the approaches of NISA and JSME FFS Code. The development of the code has been aimed to improve the accuracy and reliability of analysis by introducing new analysis methodologies and algorithms considering the latest knowledge in the SCC assessment and fracture criteria of piping. In addition, the accuracy of flaw detection and sizing at in-service inspection and residual stress distribution were modeled based on experimental data and introduced into PASCAL-SP. This code has been developed for a cross-check use by the regulatory body in Japan. In addition to this, this code can also be used for a research purpose by researchers in academia and industries. This report provides the user's manual and theoretical background of the code. (author)

    In order to validate the operational performance of the PAFS, KAERI has performed the experimental investigation using the PASCAL (PAFS Condensing heat removal Assessment Loop) facility. In this study, we simulated the KAERI PASCAL SS-540-P1 test with MARS-KS V1.4 and TRACE V5.0 p4 codes to assess the code predictability for the condensation heat transfer inside the passive auxiliary feedwater system. We simulated the KAERI PASCAL SS-540-P1 test with MARS-KS V1.4 and TRACE V5.0 p4 codes to assess the code predictability for the condensation heat transfer inside the passive auxiliary feedwater system. The calculated results of heat flux, inner wall surface temperature of the condensing tube, fluid temperature, and steam mass flow rate are compared with the experimental data. The result shows that the MARS-KS generally under-predict the heat fluxes. The TRACE over-predicts the heat flux at tube inlet region and under-predicts it at tube outlet region. The TRACE prediction shows larger amount of steam condensation by about 3% than the MARS-KS prediction.

    Full Text Available Resumo O Encontro Nacional Universitário da Diversidade Sexual (ENUDS surgiu no ano de 2003 e reúne desde então, com edições anuais, grupos e coletivos que se articulam em torno da temática sobre gênero e sexualidade, consolidando-se como espaço de discussão acadêmica e política. Este artigo é uma análise dos desdobramentos da pesquisa que buscou reconstruir a trajetória socioantropológica dos Encontros. O objetivo é explorar o modo como se apresentam os ideais de liberdade sexual, de dissolução das hierarquias e convenções de gênero e a prática política da “fechação”. Tais ideais são entendidos como dimensões estéticas das manifestações presentes nos espaços do ENUDS a partir de uma categoria central observada no campo: a “experiência”. Procura-se, para isso, explorar os argumentos que justificam essa “vivência”, bem como os momentos de limites e tensões desses ideais num espaço político que se apresenta como “coletivo”, “horizontal” e “não institucionalizado”.

    2006-09-01

    As a part of the aging structural integrity research for LWR components, the probabilistic fracture mechanics (PFM) analysis code PASCAL (PFM Analysis of Structural Components in Aging LWR) has been developed in JAEA. This code evaluates the conditional probabilities of crack initiation and fracture of a reactor pressure vessel (RPV) under transient conditions such as pressurized thermal shock (PTS). The development of the code has been aimed to improve the accuracy and reliability of analysis by introducing new analysis methodologies and algorithms considering the recent development in the fracture mechanics and computer performance. PASCAL Ver.1 has functions of optimized sampling in the stratified Monte Carlo simulation, elastic-plastic fracture criterion of the R6 method, crack growth analysis models for a semi-elliptical crack, recovery of fracture toughness due to thermal annealing and so on. Since then, under the contract between the Ministry of Economy, Trading and Industry of Japan and JAEA, we have continued to develop and introduce new functions into PASCAL Ver.2 such as the evaluation method for an embedded crack, K I database for a semi-elliptical crack considering stress discontinuity at the base/cladding interface, PTS transient database, and others. A generalized analysis method is proposed on the basis of the development of PASCAL Ver.2 and results of sensitivity analyses. Graphical user interface (GUI) including a generalized method as default values has been also developed for PASCAL Ver.2. This report provides the user's manual and theoretical background of PASCAL Ver.2. (author)

    2012-01-01

    Full Text Available Este artigo objetiva demonstrar que, no artigo O que é Esclarecimento?(1784, a noção de liberdade crítica de Immanuel Kant se inscreve no reformismo elitista ilustrado, a partir de uma chave de referenciais luteranos que rompem com os códigos estéticos e sociais da nobreza prussiana, corroborando, neste aspecto, com o mesmo tipo de crítica estético-social que observamos na primeira geração do romantismo alemão. Por fim, será possível perceber que o artigo de Kant oferece uma solução moral para o dilema protestante da relação entre consciência particular e obediência às autoridades civis.

    Precise control of large, complex systems is not assured unless there is known to be no unintended interactions in the control system. The software controlling the sustaining neutral-beam power supplies of the Mirror Fusion Test Facility accomplishes this feat. The software structures comprise some 16,000 lines of commented Pascal code, distributed amoung 10 different tasks. Each task may control any of the 24 power supplies. All the tasks are strictly event-driven, and are not subject to any system mode. Since there is no global information in the software, we know that all the power supplies are controlled independently

    Full Text Available A dinâmica do crescimento econômico contínuo vigente no capitalismo financeiro tem se mostrado incompatível com os limites planetários. A humanidade se encontra em um impasse ético, econômico e tecnológico. O modelo de produção e consumo vigente se mostra insuficiente para assegurar condições de vida digna para toda a humanidade no presente e aponta para uma deterioração dessas condições em um futuro próximo. Este artigo realiza uma revisão bibliográfica de trabalhos clássicos na teoria do desenvolvimento sustentável e, por meio da abordagem crítica da economia capitalista, coloca em xeque o conceito hegemônico do progresso e aponta a insuficiência do paradigma do crescimento para assegurar o desenvolvimento sustentável. Mesclando e conjugando as ideias dos principais autores dessas áreas, o artigo conclui que a sustentabilidade do desenvolvimento requer condicionantes que, ao longo do tempo, se tornam mais difíceis de serem alcançados. A dinâmica atual do sistema econômico leva a desgastes ambientais com efeitos cada vez mais severos, que serão sentidos especialmente a partir de 2030, podendo chegar a um colapso antes de 2100, comprometendo a capacidade de sobrevivência humana no planeta. A sustentabilidade, a suficiência e a equidade do desenvolvimento exigem uma mudança estrutural no paradigma de produção e de consumo. Para tanto, se fazem necessários mecanismos sociais, institucionais e informacionais, além da adequação e da coordenação dos avanços tecnológicos.

  19. Prudential Versus Probative Arguments for Religious Faith: Descartes and Pascal on Reason and Faith

    Directory of Open Access Journals (Sweden)

    Dennis Sansom

    2017-07-01

    Full Text Available In this article, I show that Pascal’s prudential agenda, centered on the Wager, more successfully overcomes the restrictions of Pyrrhonic skepticism expressed by Montaigne than Descartes’ probative philosophy, which was based on his “ontological argument” for God’s existence. Descartes’ attempt to base natural science on the metaphysical certainty of a non-deceiving God fails because he cannot prove that a non-deceiving Perfect Being is a “clear and distinct” idea. Pascal’s attempt to base the knowledge of God upon the “reasons of the heart” accepts the epistemological restrictions of skepticism but provides a reason to develop passionate faith, thereby overcoming skepticism. I also show that Descartes and Pascal had different assumptions about the workings of the mind; Descartes relied on a model of the mind as a “theater,” which hindered his agenda, and Pascal upon a “holistic” model, which enabled him to make a prudential argument which was cognitively convincing.

    Full Text Available O objetivo deste artigo é fundamentar a escolha pela perspectiva teórica do materialismo histórico-geográfico, desenvolvida pelo geógrafo David Harvey para compreender uma região. Para tanto, apresentamos e discutimos também os referenciais predominantes nas análises sobre regiões, com o intuito de demonstrar os limites desses referenciais e as possibilidades abertas pela perspectiva de Harvey. Assim, apresentamos alguns dos principais conceitos que têm orientado as ações de governos dos mais diversos matizes; a abordagem de David Harvey bem como seus pressupostos teóricos e históricos; e uma análise comparativa em que demonstramos as limitações dos referenciais predominantes e as possibilidades da perspectiva do último autor. Ao final, conclui-se que o materialismo histórico-geográfico permite compreender que as dinâmicas sociais e econômicas de uma região se caracterizam em processos conflituosos e contraditórios e resultam em uma configuração regional específica e transitória.

    Full Text Available O presente artigo trás reflexões sobre a importância dos Núcleos de Estudos Agroecológicos (NEAs criados via políticas do Governo Federal. No contexto analisado, os NEAs se apoiam, invariavelmente, nas lógicas familiares de produção como protagonistas de um novo formato de ensino, pesquisa e extensão. Baseado em uma revisão documental e teórica, observou-se que a proposta de criação dos núcleos trás como inovação, princípios para a construção coletiva de conhecimentos agroecológicos, ou seja, socialmente elaborados e considerando as múltiplas dimensões do desenvolvimento regional. Para a criação desses NEAS em todo o território nacional, fez-se necessário o envolvimento ativo dos mais diversos atores sociais e as IES, possibilitando uma nova perspectiva epistemológica, onde o saber popular ganha em reconhecimento e contribui na busca de resoluções de demandas sociais locais, sejam elas produtivas, educacionais, ecológicas, tecnológicas etc. Vale salientar que por meio desses ambientes coletivos, novos cenários Institucionais surgiram. A própria criação de novas IES, especialmente nas regiões mais distantes dos grandes centros urbanos, mostrou uma maior sensibilidade na incorporação de demandas locais da sociedade civil. E, mesmo com limites bem marcados dessa iniciativa pública, em menos de uma década essa ação vem proporcionando uma efetiva articulação regional e nacional de novos formatos de IES, tornando os NEAs referências no debate em torno de temas estratégicos ligados a perspectiva agroecológica.

    Abstract Introduction: Radiosurgery is an emerging terapeutich approach for the treatment of brain metastases (BMs), considering the effective local control obtained without neurological impairment. Different technological modalities have been used: Gammaknife, Cybernife, or Linac with comparable results and different incidence of symptomatic radionecrosis. To date no comparative randomized studies have been published on this matter. We draw this randomized phase III trial with the aim to evaluate incidence of symptomatic radionecrosis using gamma knife radiosurgery versus linac based (EDGE) radiosurgery. Local control (LC) rate and patients overall survival (OS) were assessed as well. Materials: Patients with limited BMs (up to 4) from different solid tumors, except SCLC or hematologic malignancies, were enrolled. Inclusion criteria were a histopatological diagnosis of malignant primary tumor, a KPS ≥70, RPA class I-II, and BMs with maximum diameter ≤3 cm and/or with a total tumor volume <30 cm3. The total dose prescribed was 24 Gy for BMs ≤ 20 mm or 4.2 cm3, and 20 Gy for BMs 21–30 mm or volume <14.1 cm3 as suggested by RTOG guidelines. Clinical outcome was evaluated by neurological examination and MRI at 2 months after SRS and then every 3 months. The radionecrosis was considered the presence of central hypodensity and peripheral enhancement on T1-weighted post-contrast imaging, with edema on T2-weighted sequences and a clear lack of perfusion without any nodular highly vascularized area within the contrast enhanced lesion on perfusion MRI. Local progression was defined as radiographic increase of the enhancing abnormality in the irradiated volume on serial MR imaging, and distant failure by the presence of new brain metastases or leptomeningeal enhancement outside the irradiated volume. Results: From October 2014 to December 2015, 101 consecutives patients of the expected 250, for 167 BMs treated, were evaluated. The most common primary

    As a part of the aging and structural integrity research for LWR components, a new PFM (Probabilistic Fracture Mechanics) code PASCAL (PFM Analysis of Structural Components in Aging LWR) has been developed since FY1996. This code evaluates the failure probability of an aged reactor pressure vessel subjected to transient loading such as PTS (Pressurized Thermal Shock). The development of the code has been aimed to improve the accuracy and reliability of analysis by introducing new analysis methodologies and algorithms considering the recent development in the fracture mechanics methodologies and computer performance. The code has some new functions in optimized sampling and cell dividing procedure in stratified Monte Carlo simulation, elastic-plastic fracture criterion of R6 method, extension analysis models in semi-elliptical crack, evaluation of effect of thermal annealing and etc. In addition, an input data generator of temperature and stress distribution time histories was also prepared in the code. Functions and performance of the code have been confirmed based on the verification analyses and some case studies on the influence parameters. The present phase of the development will be completed in FY2000. Thus this report provides the user's manual and theoretical background of the code. (author)

    Deep Learning (DL) algorithms have become ubiquitous in data analytics. As a result, major computing vendors --- including NVIDIA, Intel, AMD, and IBM --- have architectural road-maps influenced by DL workloads. Furthermore, several vendors have recently advertised new computing products as accelerating large DL workloads. Unfortunately, it is difficult for data scientists to quantify the potential of these different products. This paper provides a performance and power analysis of important DL workloads on two major parallel architectures: NVIDIA DGX-1 (eight Pascal P100 GPUs interconnected with NVLink) and Intel Knights Landing (KNL) CPUs interconnected with Intel Omni-Path or Cray Aries. Our evaluation consists of a cross section of convolutional neural net workloads: CifarNet, AlexNet, GoogLeNet, and ResNet50 topologies using the Cifar10 and ImageNet datasets. The workloads are vendor-optimized for each architecture. Our analysis indicates that although GPUs provide the highest overall performance, the gap can close for some convolutional networks; and the KNL can be competitive in performance/watt. We find that NVLink facilitates scaling efficiency on GPUs. However, its importance is heavily dependent on neural network architecture. Furthermore, for weak-scaling --- sometimes encouraged by restricted GPU memory --- NVLink is less important.

    Full Text Available O objetivo do artigo consistiu em discutir a medicalização do risco para a psicose; especificamente, a construção de uma nova categoria diagnóstica que vem sendo realizada pela força-tarefa de elaboração do DSM-5, nomeada "síndrome de risco para a psicose" e, mais recentemente, "síndrome dos sintomas psicóticos atenuados". A metodologia utilizada foi a revisão bibliográfica. Foi realizado um breve relato da genealogia do risco na psiquiatria. Na parte inicial do artigo, procurou-se discutir a medicalização de uma forma mais geral, focando sobre os aspectos do controle social e das tecnologias do self, sob uma ótica foucaultiana. Posteriormente, foi dada ênfase ao processo da medicalização do risco para a psicose; em especial, à construção de uma categoria relacionada a esse risco. Dentre os alcances desse processo, destacou-se a possibilidade de se intervir precocemente na psicose e com isso retardar seu início. Ainda não está claro se a intervenção precoce pode reduzir a gravidade do quadro quando instalado ou mesmo impedir seu aparecimento. Quanto aos limites, mostrou-se o risco de se produzir uma hipermedicalização com a construção da categoria, levando ao uso indiscriminado de medicamentos neurolépticos e aos riscos relacionados a esse uso, bem como à estigmatização dos indivíduos incluídos na categoria. Foi mostrado também o problema do elevado número de indivíduos "falsos positivos", ou seja, indivíduos que serão categorizados e mais tarde não desenvolverão qualquer transtorno psicótico. Procurou-se com o trabalho estabelecer uma crítica consistente à construção da categoria nosológica em questão.This paper aimed to discuss the medicalization of the risk for psychosis, and more specifically, the building of a new diagnostic category which has been carried out by the DSM-5 elaboration Task Force, named psychosis risk syndrome and, more recently, attenuated psychotic symptoms syndrome.

    The possibility that life can exist within previously unconsidered habitats is causing us to expand our understanding of potential planetary biospheres. Significant populations of living organisms have been identified at depths extending up to several km below the Earth's surface; whereas laboratory experiments have shown that microbial species can survive following exposure to GigaPascal (GPa) pressures. Understanding the degree to which simple organisms such as microbes survive such extreme pressurization under static compression conditions is being actively investigated. The survival of bacteria under dynamic shock compression is also of interest. Such studies are being partly driven to test the hypothesis of potential transport of biological organisms between planetary systems. Shock compression is also of interest for the potential modification and sterilization of foodstuffs and agricultural products. Here we report the survival of Shewanella oneidensis bacteria exposed to dynamic (shock) compression. The samples examined included: (a) a "wild type" (WT) strain and (b) a "pressure adapted" (PA) population obtained by culturing survivors from static compression experiments to 750 MPa. Following exposure to peak shock pressures of 1.5 and 2.5 GPa the proportion of survivors was established as the number of colony forming units (CFU) present after recovery to ambient conditions. The data were compared with previous results in which the same bacterial samples were exposed to static pressurization to the same pressures, for 15 minutes each. The results indicate that shock compression leads to survival of a significantly greater proportion of both WT and PA organisms. The significantly shorter duration of the pressure pulse during the shock experiments (2-3 μs) likely contributes to the increased survival of the microbial species. One reason for this can involve the crossover from deformable to rigid solid-like mechanical relaxational behavior that occurs for

    Full Text Available A economia brasileira vivenciou um ciclo expansivo ao longo da década de 2000, marcado pela expansão do investimento, geração de empregos e aumento da renda corrente. Após a crise econômica de 2008, que, apesar de ter seu epicentro nos mercados de dívida hipotecária norte-americana, se alastrou para várias economias do mundo, a economia brasileira entrou em uma fase de baixo crescimento, queda dos investimentos, mas com manutenção do nível de emprego. Este trabalho tem por objetivo mostrar que o recente ciclo da economia brasileira está intimamente relacionado aos mercados externos, tanto na sua fase expansiva, quanto na recessiva. Os elevados saldos em transações correntes diminuíram a dependência em relação ao capital externo para manter a estabilidade de preços, o que permitiu reduzir a taxa de juros e desvencilhar o investimento agregado. O próprio aumento da renda interna contribuiu para a redução do saldo comercial, mas a crise de 2008 intensificou este movimento, reduzindo as taxas de crescimento da economia nacional. Desta forma, a economia brasileira voltou a depender da entrada de capitais para a manutenção da estabilidade de preços e do arcabouço de políticas macroeconômicas que favorecem este movimento, a sacrificar ainda mais o crescimento do produto.

    In safety related computer applications, as in the case of a reactor protection system considered here, mostly multi-computer systems are necessary for reasons of reliability and availability. The hardware structure of the protection system and the software requierements derived from it are explained. In order to study the effects of diversified programming of the three computers the protection codes were implemented in the languages IFTRAN, PASCAL, and PHI2. According to the experience gained diversified programming seems to be a proper means to prevent identical programming errors in all three computers on one hand and to detect ambiguities of the specification on the other. During all of the experiment the errors occurring were recorded in detail and at the moment are being evaluated. (orig./WB) [de

    Full Text Available Aim: To systematically refine and recommend parameter settings of spot size, power, and treatment duration using the Pascal® photocoagulator, a multi-spot, semi-automated, short-duration laser system. Materials and Methods: A retrospective consecutive series with 752 Caucasian eyes and 1242 laser procedures over two years were grouped into, (1 374 macular focal / grid photocoagulation (FP, (2, 666 panretinal photocoagulation (PRP, and (3 202 barrage photocoagulation (BP. Parameters for power, duration, spot number, and spot size were recorded for every group. Results: Power parameters for all groups showed a non-gaussian distribution; FP group, median 190 mW, range 100 - 950 mW, and PRP group, median 800 mW, range 100 - 2000 mW. On subgroup comparison, for similar spot size, as treatment duration decreased, the power required increased, albeit in a much lesser proportion than that given by energy = power x time. Most frequently used patterns were single spot (89% of cases in FP, 5 Χ 5 box (72% in PRP, and 2 Χ 2 box (78% in BP. Spot diameters as high as ≈ 700 μm on retina were given in the PRP group. Single session PRP was attempted in six eyes with a median spot count of 3500. Conclusion: Overall, due to the small duration of its pulse, the Pascal® photocoagulator tends to use higher powers, although much lower cumulative energies, than those used in a conventional laser. The consequent lesser heat dissipation, especially lateral, can allow one to use relatively larger spot sizes and give more closely spaced burns, without incurring significant side effects.

Passa em revista o conceito de cidadania, lembrando que, como pertencimento, esta implica um processo de identificação que se desenvolve com base em referências a partir das quais se define a inclusão ou a exclusão dos indivíduos – daí a possibilidade de uma interseção entre os campos de significação dos conceitos de inclusão digital e cidadania. Mas, chamando a atenção para o conceito de cidadania ativa, conclui que, embora a rede possa potencializar a ação daqueles que já possuem algum grau de comprometimento/engajamento, não se consegue solucionar no nível da tecnologia questões que pertencem ao âmbito mais geral das relações sociais e políticas.Abstract: Starting from the assumption of inedited conditions for the exercise of citizenship brought or enhanced by the digital technology mainly the internet, this paper discusses the origins of the uneasiness currently experienced by citizenship, reflecting on the real possibilities of a “technological solution”.

    Full Text Available Recognizing contextualized subject is giving visibility to the status of person, the possibility of manifestation of identity. It materializes through indifference to the social differences that prevent the equal level identification. Nowadays, the struggle for justice and recognition is not an individual problem, it is important to the society as a whole. For adolescents, the limits of recognition can be seen in different dimensions, wherein the step of life with its own cultural features; the particularly difficult economic conditions; cultural legal perspective from the impossibility of intercultural dialogue; and yet, the boundaries of the state, absent in the effectiveness of rights. This reality is revealed in when observing the mortality rates of this public in recent years in Brazil. Young people between 15 and 19 years are the main victims of homicides in the country: 87.6 % of cases (data NEV -USP. These deaths occur mainly where there is an overlap gap and violation of rights. Violence is a complex process, but it is imperative to dialogue and respect the difference, which must be a starting point in relation to where you want to reach: that is to respect the others as equal, without prejudiced ideas. Reconhecer os sujeitos contextualizados é dar visibilidade à condição de pessoa, com possibilidade de manifestação da identidade.

    Two molybdenite samples from the Middle-Low Reaches of the Yangtze River were dated by both Os-Os and Re-Os methods. Os-Os and Re-Os dating give identical age results for the two samples. An experiment of step distillation of Os-Os method suggests that no isotopic fractionation is observed between fractions obtained by the experiment. The results prove that the Os-Os method can avoid the problems in the Re-Os method, simplify the experimental procedure, give creditable age data, and have unique advantage that no quantitative extracting of Os is required

    The Polar regions are important components in the global climate system. The widespread surface snow and ice cover strongly impacts the surface energy budget, which is tightly coupled to global atmospheric and oceanic circulations. The coupling of sea ice, clouds and aerosol in the transition zone between Open Ocean and sea ice is the focus of the PASCAL investigations to improve our understanding of the recent dramatic reduction in Arctic sea-ice. A large variety of active/passive remote sensing, in-situ-aerosol observation, and spectral irradiance measurements have been obtained during the German research icebreaker POLARSTERN expedition PS106, and provided detailed information on the atmospheric spatiotemporal structure, aerosol and cloud chemical and microphysical properties as well as the resulting surface radiation budget. Nearly identical measurements at the AWIPEV Base (German - French Research Base) in Ny-Ålesund close to the Open Ocean and collocated airborne activities of the POLAR 5 and POLAR 6 AWI aircraft in the framework of the ACLOUD project have been carried out in parallel. The airborne observations have been supplemented by observations of the boundary layer structure (mean and turbulent quantities) from a tethered balloon reaching up to 1500 m, which was operated at an ice floe station nearby POLARSTERN for two weeks. All observational activities together with intense modelling at various scales are part of the German Collaborative Research Cluster TR 172 "Arctic Amplification" that aims to provide an unprecedented picture of the complex Arctic weather and climate system. The presentation provides an overview of the measurements on-board POLARSTERN and on the ice floe station during PASCAL from May 24 to July 21 2017. We conclude how these and future similar measurements during the one-year ice drift of POLARSTERN in the framework of MOSAiC help to reduce uncertainties in Arctic aerosol-cloud interaction, cloud radiative forcing, and surface

    Full Text Available Historicamente, os processos democráticos e participativos na sociedade brasileira, e, em específico no âmbito escolar, têm sido permeados por intermitências, fragilidades e resistências ocasionadas por múltiplas determinações. O texto enfoca aspectos concernentes à organização do trabalho educativo mediante dois ângulos de análise: o primeiro ângulo refere-se aos constructos sociais de natureza estrutural e orgânica ligados às relações de poder e práticas anti-democráticas da sociedade em geral. O segundo ângulo referencia-se em uma pesquisa de tipo etnográfica, realizada no interior de uma escola pública mineira. Buscamos apreender os desafios na construção de práticas e estratégias em prol de processos participativos da comunidade escolar na elaboração do projeto político pedagógico e no funcionamento do conselho escolar. Propomo-nos com essas análises contribuir com reflexões sobre a condição do professor, enquanto sujeito, na organização do trabalho escolar mediante conexões com as atividades laborais correlatas à sua práxis cotidiana.

    Patricia Martínez García

    2013-04-01

    Full Text Available In Boutès (2008 Pascal Quignard rescues the figure of this pre-Homeric neglected hero, hidden in one of the best known mythological legends, that of Ja-son and Argona, to which Apollonius of Rhodes only dedicates but a few lines. Contrary to Ulysses and Orpheus, Butes abandons the rowing and lets himself be carried away by the sirens’ chant. In Quignard´s opinion, he dissents from the exemplary model of the heroes that have founded our culture, and dissociates himself from the group that tries to enclose and domesticate the outcast. Based on Quignard´s reading of this myth, we propose an approach to his writing as a token of ethic and aesthetic dissidence, affecting different aspects: dissidence from prevailing models of socialization, dissi-dence from traditional literary forms and conventional genres, dissidence from meta-narratives and their linear vision of history, and finally, dissidence from modern conceptions of time and progress.

    Full Text Available Apesar do amplo processo de desestatização ocorrido internacionalmente nas décadas de 1980 e 1990, as empresas estatais permanecem desempenhando significativo papel na implementação de políticas públicas e na oferta de bens e serviços à sociedade. Entretanto, sua natureza institucional e estrutura de controle tornam complexas as definições de seus objetivos operacionais, a avaliação de seu desempenho, e a própria gestão executiva das empresas, já que sua atuação está sujeita tanto às necessidades de seu controlador imediato, o governo; quanto aos interesses difusos de seu controlador indireto, a sociedade, além das expectativas de retorno financeiro dos sócios privados nas sociedades de economia mista. No momento que a Organização para a Cooperação e Desenvolvimento Econômico (OCDE propõe diretrizes para a governança corporativa de empresas estatais, que estabelecem referências para o relacionamento entre Estado, conselheiros, gestores, investidores e outras partes interessadas, este artigo avalia essas diretrizes quanto à adequação das propostas ao contexto das estatais brasileiras e sua possibilidade de implementação.Despite the extensive process of privatization that has been undertaken in many countries during the 80s and 90s, the state-owned enterprises (SOEs remain performing an important role in the implementation of public policies and in the offering of goods and services to the society.

Por outro, avaliar as razões da maior eficácia da Coroa de quinhentos quando comparada com os governos da segunda metade de Setecentos, em termos de reforma das estruturas de apoio social e implementação de um novo paradigma assistencial.

On the other hand, to evaluate the reasons why the Crown of the 16th century was more efficient when compared with the governments of the second half of the 18th century, in terms of reform of the social structures and implementation of a new paradigm of assistance. In both cases, taking into account the differences between the political and social contexts of those two moments.

    Full Text Available Objetivando compreender o modo como foram tratadas, em serviços de saúde especializados, as demandas reprodutivas das pessoas vivendo com HIV/AIDS, desenvolveu-se estudo de natureza qualitativa, utilizando-se como referencial teórico o conceito de Necessidades em Saúde e como estratégia metodológica a Observação Participante. O estudo indicou que os trabalhadores compreenderam as demandas reprodutivas como das mulheres, ligadas ao controle da transmissão vertical do HIV. As demandas reprodutivas não foram tomadas como objeto do trabalho coletivo. Foram evidenciadas diferentes racionalidades técnicas, éticas e morais. No pólo dos trabalhadores predominou a lógica do controle da epidemia, e no pólo dos usuários predominou as escolhas ligadas ao modo de vida, consubstanciadas no "aparecimento da gravidez". O reconhecimento da autonomia, quanto às decisões reprodutivas das pessoas vivendo com HIV/ AIDS, parece necessário para a formulação de estratégias assistenciais que respeitem os Direitos Humanos e minimizem os riscos de infecção pelo HIV.This qualitative study discusses how professionals in specialized health care services in the city of São Paulo have responded to the reproductive demands of people living with HIV/AIDS. Participant observation was the main methodological strategy; the concept of health demands was an important theoretical reference in the analysis. According to the health professionals, reproductive health demands were raised exclusively by women and related to mother-to-child HIV transmission. Reproductive issues were not recognized as patients’ needs, nor were they included among the objectives of collective staff work. Distinct technical, ethical, and moral rationalities were observed. Among health professionals, to control the epidemic was the prevailing logic, while among patients, exercising lifestyle choice was the key issue, materialized in the "unexpected advent of pregnancy".

    Strong evidence for the existence of supersymmetry in atomic nuclei has been found in the quartet of nuclei 194,195 Pt, 195,196 Au. Our attention is now focused a second quartet of nuclei, that is 193,194 Ir, 192,193 Os where the model is applicable. We investigate the heaviest osmium isotope which is accessible in a single neutron transfer reaction: 193 Os. Excitation energies are known from (d,p) and (n,γ) measurements, but there is limited information about quantum numbers, To measure absolute cross-sections and asymmetries of the 192 Os(d(tilde),p) 193 Os reaction we used our facilities at the Munich tandem accelerator. The 22 MeV beam of vector-polarised deuterons was produced by our new Stern-Gerlach-Source. Outgoing protons were analysed by the Q3D magnetic spectrograph and detected with a strip-detector. The target consisted of a metallic foil of 146 μg/cm 2 highly enriched 192 Os (99%). (author)

    A utopia pode ter um lado que eleva e um lado sinistro, mas geralmente o lado sinistro acaba destruindo o idealismo inicial. A razão para isto é que os utópicos inevitavelmente adotam uma imagem messiânica do mundo. As três revoluções messiânicas na história—a americana, a francesa e a bolchevique—foram lideradas por homens que pensavem que suas idéias eram universais. Este ensaio examina os escritos do existencialista francês Albert Camus, que argumenta que não existem valores transcendentais, ao mesmo tempo que ele não aceita o niilismo.

Ele resgata a importância do antropólogo neste cenário lembrando que a diversidade cultural faz parte da sociedade complexa, remetendo-se não apenas a grupos étnicos ou nacionais bem delimitados, mas também a diferenças de geração, gênero, sexo e classe, entre outros. Neste contexto, a tolerância passiva de modos distantes de vida assim como a aceitação pragmática de nosso próprio paroquialismo são atitudes não somente intelectualmente desonestas mas também moralmente repreensíveis. É no encontro incômodo de subjetividades variantes na sua própria sociedade que o antropólogo define seu lugar.

    We took an analysis on the clinical and radiologic findings of os odontoideum, which had been regarded as relatively uncommon disease, on 5 patients whom we have recently experienced. Our results were as follows: 1. Os odontoideums were incidentally discovered during the radiologic evaluation of traumatised 4 cases, who had been well being. Another one case of os odontoideum was associated with multiple epiphyseal dysplasia. 2. General radiologic findings of os odontoideum were a round or oval and hypoplastic ossicle separated from the base of odontoid process by wise gap. 3. Alanto-Axial instability was developed in 5 cases of os odontoideum by flexion and extension stress view of lateral cervical spine. 4. Flexion views of lateral cervical spine showed narrowing of anteroposterior diameter of spinal canal which were available at atlantoaxial level on 5 cases of os odontoidum. 5. CT myelogram and cervical myelogram showed anteriorly compressed dural sac and deformed spinal cord by body of axis at the atlanto-axial level.

    Preliminary experimental studies have demonstrated the possibility of using sodium borohydride (NaBH{sub 4}) oxidation catalysis by osmium (Os) in 2 M sodium hydroxide (NaOH) in the presence of thiourea as an inhibitor to hydrogen (H{sub 2}) evolution. The usefulness of this information for low-temperature direct fuel cells involving the anodic oxidation of fuels such as methanol, ethanol and sodium borohydride was discussed with reference to the challenge of high anode surface overpotential affecting the power output of direct fuel cells. This study examined the cyclic voltammetry features of supported colloidal Os and Os alloys with molybdenum, vanadium and tin, in the presence of NaBH{sub 4}. It also examined the potential for electrocatalysis in direct borohydride fuel cells (DBFC). Colloidal Os and Os alloys were tested for their use as electrocatalysts for oxidation of borohydride. The features of an Os cyclic voltammogram in alkaline media with and without BH{sub 4} were discussed along with the redox mediated oxidation of BH{sub 4}. Cyclic voltammetry and chronopotentiometry tests showed that colloidal Os 20 per cent weight supported on Vulcan XC-72R possessed electrocatalytic activity toward borohydride oxidation while the investigated Os-alloys were catalytically inactive. Chronopotentiometry experiments also showed that the 20 per cent weight Os gave the lowest anodic potential, and is therefore recommended as the anode electrocatalyst in direct borohydride fuel cells. 29 refs., 1 tab., 7 figs.

Deparamo-nos com um povo que ao longo da história acabou se adaptando a cada novo encontro e a cada nova região, buscando sobreviver em um mundo que busca e valoriza os seus contrários. Mesmo assim, esse povo manteve muitas de suas tradições intactas durante séculos de nomadismo. Para os ciganos nômades, a barraca é o seu lugar. Durante séculos as adjetivações negativas em relação aos ciganos aparecem em leis, decretos, matérias jornalísticas, processos criminais e também nas artes. Esses processos de exclusão fizeram e fazem parte da dinâmica dos Estados que veem os grupos ciganos como perigosos e desnecessários.

  1. Determination of (187)Os in molybdenite by ICP-MS with neutron-induced (186)Os and (188)Os spikes.

    2001-10-31

    The article describes a method for the determination of (187)Os in molybdenite by isotope dilution inductively coupled plasma-mass spectrometry (ID-ICP-MS) with neutron-induced (186)Os and (188)Os spike. The spike used in the present work was prepared in line with the principle by which artificial nuclides are produced in a nuclear reaction. The concentration and isotopic composition of osmium in the prepared spike were evaluated accurately with the isotope dilution method, using negative thermal ion mass spectrometry (N-TIMS). The advantage of this method is that using (186)Os and (188)Os double spikes can effectively compensate for the mass discrimination effects of ICP-MS. Thus, the common correction practice for mass bias in the isotope dilution method with a single spike is unnecessary. In addition, the method enables one to reduce the determined error arising from instrumental instability. The precision for the (187)Os/((186)Os+(188)Os) ratio was approximately 2% (2sigma, RSD), but in the case of (187)Os/(186)Os, (187)Os/(188)Os and (186)Os/(188)Os, precision ranged from 2.0 to 8% (2sigma, RSD). The results for (187)Os concentration in a molybdenite sample determined with this method showed good agreement with reference values.

    Mac OS X is the new Unix based version of the Macintosh operating system. It combines a high performance DisplayPDF user interface with a standard BSD UNIX subsystem and provides users with simultaneous access to a broad range of applications which were not previously available on a single system such as Microsoft Office and Adobe Photoshop, as well as legacy X11-based scientific tools and packages like IRAF, SuperMongo, MIDAS, etc. The combination of a modern GUI layered on top of a familiar UNIX environment paves the way for new, more flexible and powerful astronomical tools to be developed while assuring compatibility with already existing, older programs. In this paper, we outline the strengths of the Mac OS X platform in a scientific environment, astronomy in particular, and point to the numerous astronomical software packages available for this platform; most notably the Scisoft collection which we have compiled.

    The current that flows between the electrical test equipment and the nuclear explosive must be limited to safe levels during electrical tests conducted on nuclear explosives at the DOE Pantex facility. The safest way to limit the current is to use batteries that can provide only acceptably low current into a short circuit; unfortunately this is not always possible. When it is not possible, current limiters, along with other design features, are used to limit the current. Three types of current limiters, the fuse blower, the resistor limiter, and the MOSFET-pass-transistor limiters, are used extensively in Pantex test equipment. Detailed failure mode and effects analyses were conducted on these limiters. Two other types of limiters were also analyzed. It was found that there is no best type of limiter that should be used in all applications. The fuse blower has advantages when many circuits must be monitored, a low insertion voltage drop is important, and size and weight must be kept low. However, this limiter has many failure modes that can lead to the loss of over current protection. The resistor limiter is simple and inexpensive, but is normally usable only on circuits for which the nominal current is less than a few tens of milliamperes. The MOSFET limiter can be used on high current circuits, but it has a number of single point failure modes that can lead to a loss of protective action. Because bad component placement or poor wire routing can defeat any limiter, placement and routing must be designed carefully and documented thoroughly.

Inicialmente, essa teoria se caracterizava como contra-hegemônica, no conjunto de ideias e práticas pedagógicas “de esquerda”, e seus disseminadores a apresentavam como promessa de superação dos problemas da a alfabetização das “classes populares” e dos “filhos do analfabetismo”.

    Radioactive 191 Os and 193 Os nuclei have been aligned in an Os single crystal at temperatures down to 4 mK. From the temperature dependence of the γ-anisotropy the quadrupole frequencies vsub(Q) = e 2 qQ/h have been determined as vsub(Q)( 191 OsOs) = -278+-9 MHz and vsub(Q)( 193 OsOs) = -96+-15 MHz. With the known electric field gradient for OsOs of eq = (-4.54+-0.24) x 10 17 V/cm 2 the ground state spectroscopic quadrupole moments are deduced to be Q( 191 Os) = +2.53+-0.16 b and Q( 193 Os) = +0.87+-0.15 b.

Hence, Os isotopic data for lavas from this plume are ideal for further testing the role of core-mantle chemical exchange at the site of plume generation in the lower mantle, and for addressing the origin of Os-He isotopic variation in plumes. Recent work has shown that lavas from some plume systems (Hawaii, Noril'sk-Siberia, Gorgona) show coupled enrichments in 186Os/188Os and 187Os/188Os, not observed in upper mantle materials including abyssal peridotites. Picrites from Hawaii display a positive correlation between 186Os/188Os and He isotopes (R/Ra), where range in 186Os/188Os of 0.119834+/-28 to 0.1198475+/-29 and corresponding R/Ra from +7 to +25. These systematics are consistent with a lower mantle source for the radiogenic 186Os signal in the Hawaiian plume. The coupled Os enrichments in these plumes has been attributed to core-mantle chemical exchange, consistent with generation of the Hawaiian plume at the base of the lower mantle in D". Other potentially viable models await additional scrutiny. New He isotope and high precision 186Os/188Os and 187Os/188Os measurements for Iceland picrites show unique systematics compared to Hawaii. These picrites have 187Os/188Os ranging from 0.1297 to 0.1381 and R/Ra of +9 to +18, with generally higher R/Ra correlating with higher 187Os/188Os. Unlike the Hawaiian picrites from Hualalai and Loihi, which have coupled enrichments in 186Os/188Os and 187Os/188Os, the Iceland picrites show no enrichment 186Os/188Os - 0.1198363+/-28 (2s, n=14). Such Os-He isotopic variations require one end-member source that has high R/Ra, coupled with a long term elevated Re/Os and Pt/Os similar to that of the upper mantle. These systematics are inconsistent with either known upper mantle materials or those purported for ancient recycled slabs and may be a previously unidentified component

    Two-neutron transfer studies in Pt and Os were investigated. The extracted relative enhancement factors in Pt were found to be in excellent agreement with the 0(6) limit predictions. The differences in transfer strength between Pt and Os (t,p) could not be reproduced within the present framework of the Interacting Boson Approximation Model. 3 figures

  3. Inverse Limits

    2012-01-01

    Inverse limits provide a powerful tool for constructing complicated spaces from simple ones. They also turn the study of a dynamical system consisting of a space and a self-map into a study of a (likely more complicated) space and a self-homeomorphism. In four chapters along with an appendix containing background material the authors develop the theory of inverse limits. The book begins with an introduction through inverse limits on [0,1] before moving to a general treatment of the subject. Special topics in continuum theory complete the book. Although it is not a book on dynamics, the influen

    The rotational bands of the osmium isotopes display very interesting properties that vary with the neutron number. On the one hand the yrast bands of {sup 182,184,186}Os display a sudden and rather strong gain in aligned angular momentum,, whereas the lighter osmium nuclei such as {sup 176,178,180}Os show a more gradual increase of alignment characteristic of strongly interacting bands. In addition, an unusual rotational band has been found in {sup 178}Os. It consists of seven regularly spaced transitions about 36 keV apart which correspond closely to the spacing of the superdeformed band in {sup 152}Dy after an A{sup 5/3} normalization. this band populates the yrast band directly, and the moment of inertia J{sup (1)} is found to be much smaller than J{sup (2)}. The most likely interpretation of this is a band with large deformation which is undergoing systematic changes in deformation, pairing and/or alignment. This latter finding in particular motivated us to carry out research on the higher spin states in {sup 179}Os. Dracoulis et al. have published their results on 5 rotational bands in {sup 179}Os. In the present work we found six new bands and extended appreciably the spin limits in the other five. (author). 5 refs., 3 figs.

    The reported mission aimed at identifying practical modalities by which a more robust than now carbon price trajectory could be guaranteed on the European carbon market, at identifying conditions and modalities of integration of a carbon component into the energy taxation of European countries for sectors not concerned by the European carbon market, and at giving proposals for the implementation of a floor price for the production of electric power at the European scale. Thus, after a summary for policy makers, and a formulation of 10 proposals, this report addresses the implementation of a price corridor on the European market: description and limits of the European carbon market, existing or projected foreign examples, analysis of possible options, envisaged corridor levels, effects on European emissions, effect on companies concerned by the EU ETS, effect on other economic actors and households, opinion of GNOs, effect on bidding revenues, position of the European Commission and Parliament, follow-up modalities, legal aspects. It discusses the role of the arrangement for a quicker phasing out of coal in France: description of the French context in terms of emissions, existing carbon tariffing systems and objectives of emission reduction, objectives of the arrangement, implementation options, environmental, economic and political effects of the uniform tax, solutions and their impacts on European policies. The last part addresses the promotion of carbon pricing in the world

O objetivo principal é analisar as representações que esses profissionais constroem a respeito do Programa e do trabalho nele desenvolvido. Realizamos uma pesquisa qualitativa norteada pela Teoria das Representações Sociais. Como instrumentos de coleta de dados, utilizaram-se a observação participante e a entrevista semiestruturada. Foram entrevistados 24 profissionais, sendo três médicos, três enfermeiros, quatro auxiliares de enfermagem, dois cirurgiões-dentistas, um auxiliar de consultório dentário, dois assistentes sociais e nove agentes comunitários de saúde. Os discursos foram analisados com base na proposta de Análise de Conteúdo Temática. Observou-se que todos os entrevistados representam o PSF como uma proposta que trouxe contribuições positivas, no entanto, sublinham a ausência da integralidade e da intersetorialidade, assim como assinalam a dificuldade na organização do sistema de referência e contrarreferência para a garantia das ações com resolutividade. Em relação ao trabalho desenvolvido no Programa, os profissionais o representaram como "planejado", "organizado" e "gratificante". Porém, vários discursos ressaltaram as insatisfações salariais, o desgaste e a sobrecarga de trabalho, sugerindo que "trabalhar no PSF não é tão bom assim". As representações sociais construídas pelos entrevistados conduzem para a ideia de que não há uma harmonia entre a efetivação do programa e as diretrizes propostas pelo Ministério da Saúde. Constata-se, portanto, a necessidade de mudanças estruturais no PSF de Campina Grande, para que os objetivos dessa proposta possam, de fato, ser concretizados.This article aims at examining social representations of those professionals involved with the Family Health Program (PSF - Programa Saúde da Família in Campina Grande

    2016-09-01

    Full Text Available Peroxisomes are single membrane-bound organelles, whose basic enzymatic constituents are catalase and H2O2-producing flavin oxidases. Previous reports showed that peroxisome is involved in numerous processes including primary and secondary metabolism, plant development and abiotic stress responses. However, knowledge on the function of different peroxisome genes from rice and its regulatory roles in salt and other abiotic stresses is limited. Here, a novel prey protein, OsPEX11 (Os03g0302000, was screened and identified by yeast two-hybrid and GST pull down assays. Phenotypic analysis of OsPEX11 overexpression seedlings demonstrated that they had better tolerance to salt stress than wild type and OsPEX11-RNAi seedlings. Compared with wild type and OsPEX11-RNAi seedlings, overexpression of OsPEX11 had lower level of lipid peroxidation, Na+/K+ ratio, higher activities of antioxidant enzymes (SOD, POD and CAT and proline accumulation. Furthermore, qPCR data suggested that OsPEX11 acted as a positive regulator of salt tolerance by reinforcing the expression of several well-known rice transporters (OsHKT2;1, OsHKT1;5, OsLti6a, OsLti6b, OsSOS1, OsNHX1 and OsAKT1 involved in Na+/K+ homeostasis in transgenic plants under salinity. Ultrastructural observations of OsPEX11-RNAi seedlings showed that they were less sensitive to salt stress than wild type and overexpression lines. These results provide experimental evidence that OsPEX11 is an important gene implicated in Na+ and K+ regulation, and plays a critical role in salt stress tolerance by modulating the expression of cation transporters and antioxidant defense. Thus, OsPEX11 could be considered in transgenic breeding for improvement of salt stress tolerance in rice crop.

O presente trabalho aborda a área conurbada da Região Norte da Região Metropolitana de Belo Horizonte (RMBH, chamada de “Vetor Norte”, e sua relação com os espaços livres públicos existentes, através de análises qualitativas e quantitativas. Ainda que os espaços livres públicos sejam considerados como permanências no tecido urbano, os espaços edificados ampliam-se, respeitando ou não as legislações vigentes. A ocorrência maior deste conflito está localizada, principalmente, na área abordada, impulsionada pela construção da Linha Verde e de outros equipamentos, razão da sua escolha para o estudo. Através do conhecimento destes espaços, com base nas variáveis históricas e contemporâneas, será possível construir um referencial metodológico das relações entre os espaços livres públicos, os espaços edificados e a forma urbana. Os espaços livres podem ser considerados elementos estruturantes da forma da cidade, e de legítima importância para a qualidade de vida urbana.

    Ground state structure of A=186 to 196 Os-Pt transitional region is investigated through a self-consistent Hartree-Fock-Bogolyubov calculation employing a pairing-plus-quadrupole-plus-hexadecapole model interaction Hamiltonian. Influence of the hexadecapole degrees of freedom on the triaxiality is especially examined. A gradual prolate to oblate shape transition is found in Pt isotopes but such a change is almost abrupt in Os at A approx. = 194. This difference in behaviour of the Os and Pt isotopes is obtained only if all the hexadecapole degrees of freedom, instead of merely an axial Y 40 component, are treated fully self-consistently.

    Full Text Available O objetivo deste artigo é descrever a rotina de adolescentes de baixa renda que cuidam de seus irmãos. Participaram do estudo 20 adolescentes de 12 a 16 anos. Foi utilizada uma ficha de dados sociodemográficos, genograma familiar e entrevista semiestruturada sobre um dia de suas vidas. Organizaram-se as atividades relatadas em cinco categorias: cuidado pessoal, cuidado dos irmãos, domésticas, escolares e de lazer. A partir dessas atividades dividiram-se os participantes em três grupos: responsáveis pelo cuidado dos irmãos, ajudam suas mães e sem essas atividades. Os resultados indicaram que adolescentes de ambos os sexos cuidam dos irmãos, mas são as meninas que mais assumem tarefas domésticas. Quando responsabilizados pelo cuidado, suas atividades escolares e de lazer são prejudicadas.

    2005-01-01

    If you're one of the many Unix developers drawn to Mac OS X for its Unix core, you'll find yourself in surprisingly unfamiliar territory. Unix and Mac OS X are kissing cousins, but there are enough pitfalls and minefields in going from one to another that even a Unix guru can stumble, and most guides to Mac OS X are written for Mac aficionados. For a Unix developer, approaching Tiger from the Mac side is a bit like learning Russian by reading the Russian side of a Russian-English dictionary. Fortunately, O'Reilly has been the Unix authority for over 25 years, and in Mac OS X Tiger for Unix Gee

Participaron 17 estudiantes de una escuela pública de Porto Alegre (RS, de ambos sexos, reunidos en dos grupos focales: uno con 8 niños (8-9 años, y otro con 9 jóvenes (12-13 años, que vivían con sus padres. Cada grupo ha tenido sólo una cita en la escuela. Las informaciones fueron grabadas, transcritas y el contenido analizado a partir de los temas emergentes. De acuerdo con los niños, los conflictos conyugales van desde una discusión hasta la agresión física, son recurrientes, versan sobre cualquier tema, y su expresión es predominantemente negativa. Los niños reconocen la existencia del conflicto pero ni siempre entienden sus causas y todavía sufren sus consecuencias. Los niños adoptan distintas estrategias para lidiar con los conflictos, desde ignorarlos hasta las actitudes autodestructivas. Se concluye que los sujetos son conscientes de los conflictos conyugales de sus padres y reconocen sus repercusiones.

    Acromial fusion may not be complete until age 18-25, making it questionable to diagnose os acromiale in adolescents. Os acromiale may exist in adolescents and can be differentiated from a developing acromial ossification center based on MRI findings. A total of 128 MRIs of the shoulder were randomly and blindly reviewed retrospectively by two musculoskeletal radiologists. The MRIs consisted of two groups: (1) 56 of os acromiale in adults (25-74 years old, mean, 50) and (2) 72 consecutive of adolescents (12-17 years old, mean, 14.5). The following were assessed at the interface between the distal acromion and os acromiale/developing ossification center(s): presence of os acromiale vs. developing acromion, orientation, margins, and edema within and adjacent to it. Fifty-one adults and 49 adolescents were included. Exclusions were due to poor image quality or confounding findings (n = 7) or complete acromial fusion (n = 21 adolescents). Utilizing accepted definitions of os acromiale, all adult cases (100 %) were accurately diagnosed as os acromiale, with transverse interface orientation and irregular margins (94 %, R = 0.86, p < 0.00001). Forty-five (92 %) adolescent cases were accurately diagnosed as normally developing acromion with arched interface and lobulated margins (92 %, R = 0.92, p < 0.000001). Four (8 %) adolescent cases were diagnosed as having os acromiale, with transverse orientation and irregular margins. Thirty-five (69 %) and 46 (90 %) adults had marrow and interface edema, respectively. Six (12 %) and eight (16 %) adolescents had marrow and interface edema, respectively, including the four concluded to be os acromiale. Adolescents may have imaging findings consistent with os acromiale. The diagnosis of os acromiale should be based on imaging features and not limited by age. (orig.)

    Rhenium and osmium isotopes have been used for decades to date the formation of molybdenite (MoS 2 ), a common mineral in ore deposits and the world's main source of molybdenum and rhenium. Understanding the distribution of parent 187 Re and radiogenic daughter 187 Os isotopes in molybdenite is critical in interpreting isotopic measurements because it can compromise the accurate determination and interpretation of mineralization ages. In order to resolve the controls on the distribution of these elements, chemical and isotope mapping of MoS 2 grains from representative porphyry copper-molybdenum deposits were performed using electron microprobe and nano-scale secondary ion mass spectrometry. Our results show a heterogeneous distribution of 185,187 Re and 192 Os isotopes in MoS 2 , and that both 187 Re and 187 Os isotopes are not decoupled as previously thought. We conclude that Re and Os are structurally bound or present as nanoparticles in or next to molybdenite grains, recording a complex formation history and hindering the use of microbeam techniques for Re-Os molybdenite dating. Our study opens new avenues to explore the effects of isotope nuggeting in geochronometers.

  6. 187Os/188Os of boninites from the Izu-Bonin-Mariana forearc, IODP Exp 352

    The Izu-Bonin-Mariana (IBM) subduction zone is an ideal laboratory in which to study the evolution of a subduction zone from its initiation to the development of modern-day arc volcanism. Boninite lavas were produced in the IBM forearc region during the early stages of subduction and are thought to have been generated by flux melting the previously depleted mantle wedge. Mariana forearc mantle peridotites record unradiogenic 187Os/188Os signatures (0.1193-0.1273) supporting the existence of variably depleted mantle in this region (Parkinson et al., 1998). In order to understand the connection between the regional mantle, slab-derived fluids, and the generation of boninites, Re-Os isotopic data were measured on subset of boninite-series lavas obtained during IODP Expedition 352. Preliminary age-corrected (48 Ma) 187Os/188Os isotopic data for boninite-series lavas (sites U1439C and U1442A) are unradiogenic to modestly radiogenic (0.1254-0.1390) compared to primitive mantle (0.1296), consistent with Os isotopic data from boninite sands from the Bonin Islands (0.1279-0.1382; Suzuki et al., 2011). The least radiogenic boninites have 187Os/188Os (< 0.1296) values consistent with average MORB mantle recorded globally by abyssal peridotites (0.1238 ± 0.0042; Rudnick & Walker, 2009). However, boninite lavas were not derived from the most refractory ancient mantle recorded by Mariana peridotites. Unradiogenic boninites generally have higher Os abundances (0.043-0.567 ppb), whereas more radiogenic boninites have low Os abundances (0.015-0.036). Due to their low Os abundances, the moderately radiogenic isotopic signatures may be the result of interaction with highly radiogenic seawater or incorporation of radiogenic sediment (e.g. Suzuki et al. 2011). However, the radiogenic values could also be the result of fluid flux from the subducting Pacific plate.

Currently antivirus developers are concentrated on protecting systems from viruses that are most common and attack popular operating systems. If the system or its components are not often attacked then the antivirus products are not protecting these components as it is not profitable. The same situation is with script-viruses for UNIX OS as most experts consider that it is impossible for such viruses to get enough rights to attack. Nevertheless the main conclusion of this article is the fact that such viruses can be very powerful and can attack systems and get enough rights.

    Excited states in the very neutron-deficient isotopes 167 Os and 168 Os have been observed using the reaction 112 Sn( 58 Ni, 2pxn). The JUROSPHERE γ-ray spectrometer array was used in conjunction with the RITU gas-filled recoil separator to collect prompt γ radiation in coincidence with recoils implanted in a silicon strip detector located at the focal plane of RITU. Using a selective recoil decay tagging technique it has been possible to unambiguously assign γ-ray transitions to 167 Os and 168 Os through the characteristic α radioactivity of these nuclides. The high-spin structure of the bands is discussed in terms of quasiparticle configurations within the framework of the cranked shell model. The role of shape coexistence in 168 Os is examined with phenomenological three-band mixing calculations

    Several recent studies have raised the exciting possibility that oils can be dated using the Re-Os radioisotope system. However the exact nature of the events dated by this technique often remains unclear. Geochronologic interpretation of Re-Os data for oils is hampered by our limited knowledge of how these metals behave in petroleum systems. In particular, it is difficult to understand how isotopic homogenization, an essential prerequisite for the development of an isochronal relationship, can be achieved at the scale of a petroleum basin. The mechanisms capable of fractionating the Re/Os ratio in a suite of oils are also poorly understood. For this reason, we have performed an experimental study aimed at investigating the behavior of Re and Os during a particularly widespread phenomenon in petroleum systems, the interaction of formation waters with oils during migration. Contact experiments between natural oils and aqueous solutions enriched in Re and/or Os were carried out for varying lengths of time (6 h to 5 months), at different temperatures (25-150 °C), over a wide range of metal concentrations in the enriched solution (0.001-100 μg/g for Re; 1 and 10 ng/g for Os). In addition, the effect of oil composition on Re-Os exchange at the water-oil interface was examined by testing two oils with very different properties. All of our results demonstrate that Re and Os are transferred massively and very rapidly from the aqueous solution to the organic phase. This is true regardless of temperature or oil composition. It is also true for a very wide range of metal concentrations in the aqueous solution, up to an apparent saturation level that exceeds natural concentrations in oils by several orders of magnitude. Given the efficiency of Re and Os transfer from water to oil demonstrated here, and assuming that our findings are applicable to natural conditions, water/oil ratios of only about 250 would be needed to explain the Re and Os contents of most oils, based on

  6. 186Os- 187Os systematics of Gorgona Island komatiites: implications for early growth of the inner core

    The presence of coupled enrichments in 186Os/ 188Os and 187Os/ 188Os in some mantle-derived materials reflects long-term elevation of Pt/Os and Re/Os relative to the primitive upper mantle. New Os data for the 89 Ma Gorgona Island, Colombia komatiites indicate that these lavas are also variably enriched in 186Os and 187Os, with 186Os/ 188Os ranging between 0.1198397±22 and 0.1198470±38, and with γOs correspondingly ranging from +0.15 to +4.4. These data define a linear trend that converges with the previously reported linear trend generated from data for modern Hawaiian picritic lavas and a sample from the ca. 251 Ma Siberian plume, to a common component with a 186Os/ 188Os of approximately 0.119870 and γOs of +17.5. The convergence of these data to this Os isotopic composition may imply a single ubiquitous source in the Earth's interior that mixes with a variety of different mantle compositions distinguished by variations in γOs. The 187Os- and 186Os-enriched component may have been generated via early crystallization of the solid inner core and consequent increases in Pt/Os and Re/Os in the liquid outer core, with time leading to suprachondritic 186Os/ 188Os and γOs in the outer core. The presence of Os from the outer core in certain portions of the mantle would require a mechanism that could transfer Os from the outer core to the lower mantle, and thence to the surface. If this is the process that generated the isotopic enrichments in the mantle sources of these plume-derived systems, then the current understanding of solid metal-liquid metal partitioning of Pt, Re and Os requires that crystallization of the inner core began prior to 3.5 Ga. Thus, the Os isotopic data reported here provide a new source of data to better constrain the timing of inner core formation, complementing magnetic field paleo-intensity measurements as data sources that constrain models based on secular cooling of the Earth.

    Full Text Available O ensaio aponta a relação da filosofia com os anos 1960, tendo em vista os cruzamentos entre idéias então produzidas e aquele momento histórico. O método empregado alia interpretação histórica e interpretação filosófica, com destaque para alguns autores, como Herbert Marcuse e Michel Foucault. Conclui-se que o pensamento dos anos 1960 cunhou também uma concepção nova do que seria a própria atividade de interpretar, fatos ou idéias.

  11. A ontologia discursiva de Os sertões The discursive ontology of Os sertões

    1998-07-01

    Full Text Available Este artigo discute atributos de Os sertões, analisando sua ontologia discursiva, em particular os aspectos ligados às narrativas imaginárias e literárias. Mostra que a principal obra de Euclides conjuga pelo menos dois modos discursivos: o das ciências e um outro que caracteriza as narrativas sobre realidades imaginárias e literárias. Trechos são destacados com o objetivo de demonstrar que na sua construção híbrida participam elementos que poderiam pertencer tanto à ficção como à historiografia. Apoiando-se em Hayden White, o autor contempla três modos interpretativos da história de Canudos em Os sertões: o argumentativo, o explicativo e o ideológico. Finalmente, realiza breve comparação com A guerra do fim do mundo, de Vargas Llosa, quanto ao modo e a seqüência como são narrados os fatos.This analysis of the discursive ontology of Os sertões is particularly concerned with the book’s imaginary and literary narratives. Cunha’s main work combines at least two discursive styles: the discourse of the sciences and the discourse that characterizes narratives dealing with imaginary and literary realities. Selected excerpts show how the hybrid construction of Os sertões relies on elements which may belong to the realm of either fiction or historiography. Based on the ideas of Hayden White, the article detects three ways in which Os sertões interprets the history of Canudos: argumentative, explanatory, and ideological. The text ends with a brief comparison of the narration and sequencing of facts in Vargas Llosa’s La guerra del fin del mundo and Cunha’s Os sertões.

    Full Text Available O artigo pretende compreender os limites e as possibilidades da inserção do cristianismo na província romana da Bitínia a partir do estudo de duas cartas sobre os cristãos presentes na correspondência entre Plínio, o Jovem, e Trajano. Para tanto, destacamos que nossa abordagem concebe o Império Romano como um espaço de integração, o que favorece o estudo de aspectos que excedem as relações do poder imperial com os seguidores dessa religião. A análise das fontes a partir dos pressupostos da historiografia recente apontou que a situação dos cristãos na provincia dependia, naquele período, da tolerância das comunidades judaicas e gregas, além da condescendência das autoridade romanas. Nesse contexto, tornar-se critão era também uma forma, embora menos valorizada, de integração no mundo romano, pois o cristianismo foi uma religião que cresceu a partir das trocas culturais e das relações de poder que ocorriam entre as comunidades presentes na província.

  18. Pacific 187Os/188Os isotope chemistry and U-Pb geochronology: Synchroneity of global Os isotope change across OAE 2

    2015-10-01

    Studies of OAE 2 sections beyond the Atlantic Ocean, Western Interior Seaway (WIS) and European pelagic shelf are limited. Here, we present initial osmium isotope stratigraphy (187Os/188Os-Osi) from two proto-Pacific sites that span the Cenomanian-Turonian boundary interval (CTBI): the Yezo Group (YG) section, Hokkaido, Japan, and the Great Valley Sequence (GVS), California, USA; to evaluate the 187Os/188Os seawater chemistry of the proto-Pacific. Additionally we combine new 206Pb/238U zircon CA-ID-TIMS geochronology from five volcanic tuff horizons of the Yezo Group section to test and facilitate inter-basinal integration with the WIS using radio-isotopically constrained age-depth models for both sections, and quantitatively constrain the absolute timing and duration of events across the CTBI. The YG shows an almost identical Osi profile to that of the WIS, and very similar to that of other sites of the proto-Atlantic and European pelagic oceans (Turgeon and Creaser, 2008; Du Vivier et al., 2014). The characteristics of the Osi profile are radiogenic and heterogeneous (∼0.55-0.85) prior to the OAE 2, and synchronous with the inferred OAE 2 onset the Osi abruptly become unradiogenic and remain relatively homogeneous (∼0.20-0.30) before showing a gradual return to more radiogenic Osi (∼ 0.70) throughout the middle to late OAE 2. A206Pb/238U zircon age of an interbedded tuff (HK017) in the adjacent horizon to the first unradiogenic Osi value constrains the age of the Osi inflection at 94.44 ± 0.14 Ma. This age, including uncertainty, agrees with the interpolated age of the same point in the Osi profile (94.28 ± 0.25 Ma) in the only other dated OAE 2 section, the WIS; indicating a coeval shift in seawater chemistry associated with volcanism at the OAE 2 onset at the levels of temporal resolution (ca. 0.1 Myr). Further, prior to the onset of OAE 2 an enhanced radiogenic inflection in the Osi profile of the YG is correlative, within uncertainty, with a similar

    Full Text Available O objetivo central deste ensaio teórico é avaliar as contribuições do pragmatismo nos Estudos Organizacionais e, os específicos, avaliar se as contribuições teóricas de Charles Peirce e John Dewey possibilitam afirmar o pragmatismo como senso comum, ciência ou teoria do conhecimento; analisar as contribuições - possibilidadese limites - do pragmatismo como conhecimento científico; compreender os percursos do pragmatismo nos Estudos Organizacionais. Chaga-se a conclusão de que ser pragmático é diferente de conceber estudos articulados no campo epistemológico do pragmatismo. O sujeito pragmático vê na sua utilidade e na necessidade deação, o ponto de tensão que coloca em dúvida a veracidade dos pressupostos do pragmatismo como ciência. O que ocorre nos Estudos Organizacionais éa conversão do pragmatismo como conhecimento científico emsubordinação irracional à utilidade e à ação prática, sobretudo, no campo da economia, da política, da ciência, da cultura, da educação, e assim por diante.

    For a very long time, Linux distros have used package-based systems in order to distribute their core packages or applications, like Debian's apt-get. While we can all recognize the strengths of this model, there are a number of things that can surely be improved. At Endless Computers, we make use of ostree and Flatpak for distributing Endless OS and its apps. ostree provides a way for distributing filesystem trees, allowing read-only OS trees and atomic upgrades. Flatpak leverages ostree for distributing apps, while also running them in a sandbox, thus making it not only a very efficient and robust way to install applications, but also a secure way of running them.

    The ν 3 bands of 187 Os 16 O 4 , 189 Os 16 O 4 , and 192 Os 16 O 4 have been recorded using both a Michelson interferometer (resolution 0.06 cm -1 ) and a tunable semiconductor diode laser (resolution limited by the Doppler width, approx.0.0007 cm -1 ). The rotational fine structure differs from that of most other spherical-top molecules, for only rotational levels of A symmetry exist. A total of 112 individual vibration--rotation lines in the P and R branches of the three isotopic species were calibrated against stimulated emission lines from a high-voltage CO 2 gain cell, and were used to determine three scalar and two tensor spectroscopic constants for each species; an additional scalar constant was obtained from an analysis of the Q branch of 192 OsO 4 . The strength of P (11) A 2 /sup ts0/ was measured for 192 OsO 4 and yields a vibrational transition moment for ν 3 of 0.17 +- 0.02 D. Transitions of all isotopic species that are expected to fall near CO 2 laser lines in the region 949--972 cm -1 are tabulated as an aid in the interpreation of saturation spectroscopy experiments. The general quadratic symmetry and valence force constants of OsO 4 were redetermined, using the isotope shifts in ν 3 as the additional constraints for the F 2 symmetry block

    An oxysulfide series of nominal compositions BiCu{sub 1−x}OS with x<0.20 has been prepared and its structural properties characterized by combining powder X-ray diffraction and transmission electron microscopy techniques. It is found that this oxysulfide, crystallizing in the P4/nmm space group, tends to adopt a constant amount of copper vacancy corresponding to x=0.05 in the BiCu{sub 1−x}OS formula. The presence of Cu vacancies is confirmed by HAADF-STEM analysis showing, in the Cu atomic columns, alternating peaks of different intensities in some very localized regions. For larger Cu deficiencies (x>0.05 in the nominal composition), other types of structural nanodefects are evidenced such as bismuth oxysulfides of the “BiOS” ternary system which might explain the report of superconductivity for the BiCu{sub 1−x}OS oxysulfide. Local epitaxial growth of the BiCuOS oxysulfide on top of CuO is also observed. In marked contrast to the BiCu{sub 1−x}OSe oxyselenide, these results give an explanation to the limited impact of Cu deficiency on the Seebeck coefficient in BiCu{sub 1−x}OS compounds. - Graphical abstract: High resolution TEM image showing a Bi(Cu)OS/Bi{sub 2}O{sub 2}S interface and corresponding dislocation region. The Bi(Cu)OS structure adopts a rather constant Cu content (near 0.95); starting from BiCuOS leads to the formation of defects such as the Bi{sub 2}O{sub 2}S oxysulfide.

  17. Rice hypersensitive induced reaction protein 1 (OsHIR1) associates with plasma membrane and triggers hypersensitive cell death.

    2010-12-30

    In plants, HIR (Hypersensitive Induced Reaction) proteins, members of the PID (Proliferation, Ion and Death) superfamily, have been shown to play a part in the development of spontaneous hypersensitive response lesions in leaves, in reaction to pathogen attacks. The levels of HIR proteins were shown to correlate with localized host cell deaths and defense responses in maize and barley. However, not much was known about the HIR proteins in rice. Since rice is an important cereal crop consumed by more than 50% of the populations in Asia and Africa, it is crucial to understand the mechanisms of disease responses in this plant. We previously identified the rice HIR1 (OsHIR1) as an interacting partner of the OsLRR1 (rice Leucine-Rich Repeat protein 1). Here we show that OsHIR1 triggers hypersensitive cell death and its localization to the plasma membrane is enhanced by OsLRR1. Through electron microscopy studies using wild type rice plants, OsHIR1 was found to mainly localize to the plasma membrane, with a minor portion localized to the tonoplast. Moreover, the plasma membrane localization of OsHIR1 was enhanced in transgenic rice plants overexpressing its interacting protein partner, OsLRR1. Co-localization of OsHIR1 and OsLRR1 to the plasma membrane was confirmed by double-labeling electron microscopy. Pathogen inoculation studies using transgenic Arabidopsis thaliana expressing either OsHIR1 or OsLRR1 showed that both transgenic lines exhibited increased resistance toward the bacterial pathogen Pseudomonas syringae pv. tomato DC3000. However, OsHIR1 transgenic plants produced more extensive spontaneous hypersensitive response lesions and contained lower titers of the invading pathogen, when compared to OsLRR1 transgenic plants. The OsHIR1 protein is mainly localized to the plasma membrane, and its subcellular localization in that compartment is enhanced by OsLRR1. The expression of OsHIR1 may sensitize the plant so that it is more prone to HR and hence can react more

    Full Text Available O presente trabalho toma por base uma abordagem psicossocial para discorrer sobre os limites impostos pelos estereótipos de gênero à construção de uma identidade masculina, em contraposição às possibilidades de subjetivação, num cenário cultural de pluralidade identitária. Ênfase é dada à socialização estereotipada dos meninos, num processo no qual se verifica uma espécie de superposição do contexto socio-histórico em que cresceram os pais àquele no qual o menino é socializado, acentuando determinadas crenças sobre gênero. O modelo tradicional de virilidade, que imperava inquestionável até bem pouco tempo, ignorando as necessidades afetivas e valorizando características como a competitividade, a preocupação com o desempenho, o autoritarismo, a dominação e a opressão, vem sendo questionado como pilar maior da identidade masculina tradicional.

    Full Text Available A República é um texto repleto de mitos, que ora são condenados, ora integrados à educação na cidade. No livro II a discussão mostra quais são condenáveis e quais são úteis. E o motivo dessa posição ambivalente de Platão a respeito do mito é um só: os mitos se imprimem na alma. Sendo assim, eles são formadores do caráter. O problema é que há mitos pseûdos, ou seja, falsos, mentirosos, fictícios. E há mitos que possuem um elemento de verdade e um elemento pseûdos. Mas eles jamais são completamente verdadeiros. Ora, qual a função do pseûdos, considerando que os mitos formam o caráter? Um discurso, seja ficcional, ou mítico, pode ser filosófico? Se isso for possível, o texto da República não é ele mesmo uma ficção? Um mito? Por breves apontamentos, este estudo segue essas questões.

    The energetically most stable orthorhombic structure of OsB2 and IrB2 is dynamically stable for OsB2 but unstable for IrB2. Both diborides have substantially lower shear strength in their easy slip systems than their metal counterparts. This is attributed to an easy sliding facilitated by out-of-plane weakening of metallic Os-Os bonds in OsB2 and by an in-plane bond splitting instability in IrB2. A much higher shear resistance of Os-B and B-B bonds than Os-Os ones is found, suggesting that the strengthened Os-B and B-B bonds are responsible for hardness enhancement in OsB2. In contrast, an in-plane electronic instability in IrB2 limits its strength. The electronic structure of deformed diborides suggests that the electronic instabilities of 5d orbitals are their origin of different bond deformation paths. Neither IrB2 nor OsB2 can be intrinsically superhard.

    1970-02-15

    The level structure of {sup 189}Os has been studied from the decay of {sup 189}Ir (13,3 days) produced in proton spallation at CERN and mass separated in the ISOLDE on-line facility. The gamma-ray spectrum has been recorded both with a high resolution Si(Li) - detector and Ge(Li) - detectors. Three previously not reported transitions were observed defining a new level at 348.5 keV. Special attention was given to the low energy level band structure. Several multipolarity mixing ratios were deduced from measured L-subshell ratios which, together with measured level half-lives, gave absolute transition probabilities. The low level decay properties are discussed in terms of the Nilsson model with the inclusion of Coriolis coupling.

    ocean island basalt sources and could potentially apply to the Gorgona suite. Crustal recycling, however, requires large proportions of very ancient recycled basaltic crust in the sources of the 187Os-enriched ultramafic rocks to explain the magnitude of 187Os enrichments observed. For example, addition of 20% oceanic crust to fertile mantle, and nearly 3 billion years are necessary to generate a reservoir with the Os isotopic composition of the most radiogenic komatiites. If the recycled oceanic crust was added to basalt-depleted mantle, as may be indicated by ɛ Nd values for the komatiites averaging about +10, even larger proportions of older crust are required. Large proportions of oceanic mafic crust in the sources of the 187Os-enriched komatiites, although petrologically conceivable under certain melting conditions, is unlikely here given the limited trace element and lithophile isotope system variations. These results raise questions about the efficacy of using Os isotopes to constrain the proportion of recycled oceanic crust in other plumes. Other possible mechanisms for generating 187Os-enriched mantle include invoking the existence of a 187Os-enriched lower mantle, and minor outer core-lower mantle interactions.

    Full Text Available O livro Os parceiros do Rio Bonito traz uma contribuição admirável ao pensamento social brasileiro por sua relevância ético-política, como obra de denúncia política e crítica social; por sua contribuição formal ou estética, uma fina arquitetura da palavra e da argumentação sociológica e antropológica; e por sua contribuição metodológica, a pertinência do ato crítico aberto e pautado pela fluidez, em contraposição à adesão irrestrita a determinado aparato teórico. À atitude crítica associa-se a atitude mental de empatia pelo objeto, que se afasta de um frio e distante "sociologismo", mas, ao mesmo tempo, se recusa a atribuir-lhe as características que "gostaríamos" que tivesse, conforme a ideologia ou as crenças que partilhamos. A radicalidade dessa obra reside no espírito aberto para a "aventura sociológica", daí resultando a inexistência de "manifestos"ou "normas" de conduta. Todavia, Candido demarca os limites entre o espírito aberto à diversidade e à versatilidade no trato do fenômeno social, de um lado, e a adesão aventureira a um relativismo estéril, de outro. Finalmente, discute-se aqui a íntima relação entre a conduta intelectual do autor - sua postura ética diante do mundo acadêmico - e sua própria obra.

A cidade brasileira mostra cotidianamente as feridas causadas pela desigual distribuição de renda e pela exclusão social: a configuração espacial do território intraurbano é o mais nítido retrato do fenômeno, que hoje representa o principal obstáculo ao desenvolvimento sustentável do país. Apesar desta evidência, os programas de redução da pobreza, desenvolvidos nos últimos anos, apresentam poucos pontos de integração com a realidade territorial. Por outro lado, a desigual distribuição de renda e a exclusão social de ampla parte da população, mesmo descrevendo detalhadamente o problema, não ajudam a identificar os pontos de partida e os elementos positivos que devem ser fortalecidos para implementar programas integrados de redução da pobreza. A história e as experiências de programas de urbanização dos últimos 25 anos podem contribuir para definir um percurso metodológico a partir das potencialidades, mesmo que adormecidas, das pessoas que vivem a situação de pobreza.

    2006-01-01

    In this work, the excited levels of 193 Ir populated by the beta - decay of 193 Os (T 1/2 ∼ 30h) were investigated. For that purpose, ∼ 5 mg samples of 99%-enriched 192 Os were irradiated under a thermal neutron flux of ∼ 10 12 s -1 and then analysed both using single gamma spectroscopy and a 4-detector multi parametric acquisition facility, which provided data for both a gamma gamma coincidence analysis and a directional angular correlation gamma gamma (θ ) study. From these data, 28 transitions were added to this decay scheme, 11 of which were previously known from nuclear reactions and 17 observed for the first time. Eight excited levels were also added to the decay scheme, 3 of which were known from nuclear reaction studies - the remaining 5 are suggested for the first time. Moreover, it was possible to confirm suspicions found in reference that the levels at 848.93 keV and 849.093 keV are indeed the same; it was also possible to confirm the existence of an excited level at 806.9 keV, which had been inferred, but not experimentally confirmed in beta decay studies to date. The angular correlation analysis allowed for the definition of the spin of the excited level at 874 keV as 5/2 +; moreover, the results showed a 79% probability that the spin of the 1078 keV level is 5/2/'-, and also restricted the spin possibilities for the new excited level at 960 keV to two values (1/2 or 3/2). It was also possible to measure the multipolarity mixing ratio (δ Ln+1 /L n ) for 43 transitions - 19 of them for the first time and most of the others with a better precision than previously known. Finally, an attempt was made to understand the low-lying levels structure for this nucleus using a theoretical model, which reproduced the ground state and the two lowest-lying excited levels in 193 Ir.

  5. Os olhos de Saddam: imagens do inimigo

    Full Text Available Na representação jornalística da captura de Saddam Hussein, as fotografias são utilizadas como “atos de guerra” na representação dos inimigos, e enfatizadas pelos circuitos midiáticos. Saddam foi capturado em um refúgio escavado debaixo da terra na zona rural: as suas condições físicas eram dignas de piedade, e impiedosamente foram imortalizadas pelos fotógrafos embedded na captura. O aspecto de seu corpo transcurado, de seu rosto inchado, de seus cabelos e de sua barba desalinhados eram o contrário de sua imagem “em majestade” entronizada em mil variantes por todo o Iraque até pouco tempo atrás. O por em cena a estética do corpo sobre a qual Saddam – como muitos políticos não necessariamente tiranos – fundou a representação de seu próprio poder, foi destruída e a interpretação de degradação ultrapassou com grande facilidade a sua imagem de honra. Nas intenções dos inimigos, desgosto e vergonha colaboravam perfeitamente para a sinalização da vitória, enquanto, entre os espectadores da parte adversária só suscitavam mais raiva, indignação, ódio e desejo de vingança. Essas fotos de Saddam, assim como, em seguida, aquelas de seu enforcamento após a sua condenação, de tratamento grotesco, representam somente um dos episódios mais significativos de uma longa “guerra de imagens” que contrapõe ainda povos e culturas, sensibilidade religiosa e política, e torna o terreno da mídia, um espaço ulterior de desencontros, ao invés de construções possíveis de comunidade. O texto se fecha entre outros sobre o estatuto ambíguo que os jornais atribuem às imagens fotográficas, de um lado utilizadas como prova incontestável do discurso verbal e, de outro, continuamente pondo em causa esse último, que as interroga, as interpreta e as coloca em dúvida, construindo um discurso sincrético a ser lido sob diversas possibilidades isotópicas.

  9. Limits on fundamental limits to computation.

    Science.gov (United States)

    Markov, Igor L

    2014-08-14

    An indispensable part of our personal and working lives, computing has also become essential to industries and governments. Steady improvements in computer hardware have been supported by periodic doubling of transistor densities in integrated circuits over the past fifty years. Such Moore scaling now requires ever-increasing efforts, stimulating research in alternative hardware and stirring controversy. To help evaluate emerging technologies and increase our understanding of integrated-circuit scaling, here I review fundamental limits to computation in the areas of manufacturing, energy, physical space, design and verification effort, and algorithms. To outline what is achievable in principle and in practice, I recapitulate how some limits were circumvented, and compare loose and tight limits. Engineering difficulties encountered by emerging technologies may indicate yet unknown limits.

    2014-11-01

    The synthesis of novel hexagonal ReB2-type OsB2 ceramic powder was performed by high energy ball milling of elemental Os and B powders. Two different sources of B powder have been used for this mechanochemical synthesis. One B powder consisted of a mixture of amorphous and crystalline phases and a mixture of 10B and 11B isotopes with a fine particle size, while another B powder was a purely crystalline (rhombohedral) material consisting of enriched 11B isotope with coarse particle size. The same Os powder was used for the synthesis in both cases. It was established that, in the first case, the hexagonal OsB2 phase was the main product of synthesis with a small quantity of Os2B3 phase present after synthesis as an intermediate product. In the second case, where coarse crystalline 11B powder was used as a raw material, only Os2B3 boride was synthesized mechanochemically. The thermal stability of hexagonal OsB2 powder was studied by heating under argon up to 876 °C and cooling in vacuo down to -225 °C. During the heating, the sacrificial reaction 2OsB2+3O2→2Os+2B2O3 took place due to presence of O2/water vapor molecules in the heating chamber, resulting in the oxidation of B atoms and formation of B2O3 and precipitation of Os metal out of the OsB2 lattice. As a result of such phase changes during heating, the lattice parameters of hexagonal OsB2 changed significantly. The shrinkage of the a lattice parameter was recorded in 276-426 °C temperature range upon heating, which was attributed to the removal of B atoms from the OsB2 lattice due to oxidation followed by the precipitation of Os atoms and formation of Os metal. While significant structural changes occurred upon heating due to presence of O2, the hexagonal OsB2 ceramic demonstrated good phase stability upon cooling in vacuo with linear shrinkage of the lattice parameters and no phase changes detected during cooling.

    Full Text Available Nas últimas décadas, tem sido aventada a hipótese do "fim da literatura". Na verdade, trata-se do fim de um tipo de literatura, o da alta modernidade. Ao mesmo tempo, apareceram e multiplicaram-se romances cuja principal personagem é um escritor famoso do fim do século XIX ou primeira metade do XX: Rimbaud, Flaubert, Dostoiévski, Henry James, Virginia Woolf, Pessoa e outros. O objetivo deste artigo é examinar as causas e as características desse tipo de romance. Os escritores "pós-modernos" veem seus predecessores como heróis e modelos? Fazem o luto de uma fase áurea da literatura e comparam-na com a literatura atual? Qual a relação desses romances com as antigas biografias? Quais as novidades formais desse novo subgênero?In the last decades the hypothesis of "the end of literature" has been put forward. It actually concerns the end of one kind of literature, that of high modernity.

The aim of this article is to examine the causes and the features of these particular novels. Do "post-modern" writers look at their predecessors as heroes and models? Are they mourning a brighter phase of literature and comparing it with the current one? What is the relation between this kind of fiction and the old biographies?

    Greditzer, Harry G.; Hutchinson, Ian D.; Geannette, Christian S.; Hotchkiss, Robert N.; Kelly, Bryan T.; Potter, Hollis G.

    2017-01-01

    Background: Os styloideum describes an accessory carpal ossicle between the trapezoid, the capitate, and the second and third metacarpals. Injuries to this tissue have been described as part of the carpal boss syndrome. While the etiology of os styloideum remains uncertain, it may represent a physiologic response to altered loading forces in the wrist, similar to the development of cam-type deformity in the hips of ice hockey players or the Bennett lesion in the shoulders of baseball pitchers. Hypothesis: Professional hockey players will have a higher prevalence of os styloideum compared with the general population. Study Design: Case series. Level of Evidence: Level 4. Methods: A retrospective review of 16 professional hockey players from 4 different National Hockey League (NHL) teams who underwent unilateral imaging of the wrist was performed. Seventeen wrists were reviewed for the presence of os styloideum. Results: Thirteen of 16 players (81%) had an os styloideum, representing an increased prevalence compared with the general population. Previous clinical and cadaveric studies estimated a general prevalence of up to 19% (P < 0.001). For the 10 players who had their leading wrist scanned, 9 had an os styloideum (90%). Ten of 11 (91%) players demonstrated a bone marrow edema pattern within the metacarpal and the os styloideum on magnetic resonance imaging. There was no significant association between the presence of an os styloideum and the player’s position, leading wrist, or years in the league. Conclusion: There appears to be an increased prevalence of os styloideum among NHL players, and team physicians should consider this finding while formulating a differential diagnosis for dorsal wrist pain. Clinical Relevance: This study identified NHL players as having an increased prevalence of os styloideum compared with the general population. By doing so, these findings represent an opportunity to enhance our understanding of the etiology, clinical significance

  4. Evaluating Re-Os systematics in organic-rich sedimentary rocks in response to petroleum generation using hydrous pyrolysis experiments

    elemental abundance data reveal limited transfer of Re and Os into the bitumen from a Type III kerogen in comparison to Type II-S kerogen (0.02% vs. 3.7%), suggesting that these metals are very tightly bound in Type III kerogen structure. The 187Os/188Os data from the pyrolysis generated Phosphoria bitumens display minor variation (4%) across the experimental temperatures, with values similar to that of the source rock. This indicates that the isotopic composition of the bitumen reflects the isotopic composition of the source rock at the time of petroleum generation. These data further support the premise that the Os isotopic composition of oils and bitumens can be used to fingerprint petroleum deposits to specific source rocks. Oil generated through the hydrous pyrolysis experiments does not contain appreciable quantities of Re or Os (~120 and ~3 ppt, respectively), in contrast to natural oils (2–50 ppb and 34–288 ppt for Re and Os, respectively), which may suggest that kinetic parameters are fundamental to the transfer of Re and Os from source rocks to oils. From this we hypothesise that, at the temperatures employed in hydrous pyrolysis, Re and Os are assimilated into the extracted rock as a result of cross-linking reactions.

    2014-03-01

    Full Text Available The neutron-rich isotopes of tungsten, osmium and platinum have different shapes in their ground states and present also shape transitions phenomena. Spectroscopic information for these nuclei is scarce and often limited to the gamma rays from the decay of isomeric states. For the neutron-rich even-even osmium isotopes 194Os and 198Os, a shape transition between a slightly prolate deformed to an oblate deformed ground state was deduced from the observed level schemes. For the even-even nucleus lying in between, 196Os, no gamma ray transition is known. In order to elucidate the shape transition and to test the nuclear models describing it, this region was investigated through gamma-ray spectroscopy using the AGATA demonstrator and the large acceptance heavy-ion spectrometer PRISMA at LNL, Italy. A two-nucleon transfer from a 198Pt target to a stable 82Se beam was utilized to populate medium-high spin states of 196Os. The analysis method and preliminary results, including the first life-time measurement of isomeric states with AGATA, are presented.

Esses movimentos consideram sua religião como o repositório de verdade absoluta, a fonte derradeira que legitima as leis humanas. Assim, conquanto sejam pós-seculares, ao mesmo tempo tentam transformar os princípios religiosos em agendas políticas. Com efeito, os militantes agem frequentemente de acordo com princípios políticos, procurando afirmar o primado de sua própria fé sobre a dos outros. Eles se movem dentro das sociedades contemporâneas em nome de uma teologia política radical. Os principais argumentos baseiam-se em dois estudos de caso: o Bodu Bala Sena no Sri Lanka e os movimentos para o Hindutva na Índia.

    2006-08-01

    Superhard materials have many industrial applications, wherever resistance to abrasion and wear are important. The synthesis of new superhard materials is one of the great challenges to scientists. We re-examined the phase diagram of the binary osmium-boron system and confirmed the existence of two hexagonal phases, OsB 1.1, Os 2B 3, and an orthorhombic phase, OsB 2. Almost nothing is known about the physical properties of osmium borides. Microhardness measurements show that OsB 2 is extremely hard. Ab initio calculations show that this is due to formation of covalent bonds between boron atoms. OsB 2 is also a low compressibility material. It can be used as hard coating.

    Full Text Available Resumo O objetivo do estudo foi analisar a influência do perfeccionismo nos comportamentos de risco para os transtornos alimentares de atletas adolescentes do sexo feminino da modalidade atletismo. Fizeram parte do estudo 52 atletas da modalidade de atletismo de clubes da cidade de São Paulo/SP com idade entre 12 e 17 anos. Utilizaram-se as subescalas do Eating Attitudes Test (EAT-26 e a Multidimensional Perfectionism Scale (MPS para avaliar os comportamentos de risco para os transtornos alimentares e os traços perfeccionistas, respectivamente. Conduziu-se a regressão linear múltipla stepwise para analisar a influência dos perfeccionismo nos comportamentos de risco para os transtornos alimentares. Os resultados indicaram influência da MPS nos escores das subescalas Dieta (F(1, 44 = 5,74; p = 0,05 e Autocontrole Oral (F(1, 44 = 6,13; p = 0,04 do EAT-26. No entanto, não foi evidenciado impacto da MPS nos escores da subescala Bulimia e Preocupação com 0 Alimenta (F(1, 44 = 1,26; p = 0,22. Assim, em razão da investigação apresentar delineamento transversal, pressupõe-se que as atletas de atletismo com traços perfeccionistas podem estar mais susceptíveis para a restrição alimentar e a influência ambiental para a ingesta alimentar.

  18. JET pump limiter

    International Nuclear Information System (INIS)

    Sonnenberg, K.; Deksnis, E.; Shaw, R.; Reiter, D.

    1988-01-01

    JET plans to install two pump limiter modules which can be used for belt-limiter, inner-wall and X-point discharges and, also, for 1-2s as the main limiter. A design is presented which is compatible with two diagnostic systems, and which allows partial removal of the pump limiter to provide access for remote-handling operations. The high heat-flux components are initially cooled during a pulse. Heat is removed between discharges by radiation and pressure contacts to a water-cooled support structure. The pumping edge will be made of annealed pyrolytic graphite. Exhaust efficiency has been estimated, for a 1-d edge model, using a Monte-Carlo calculation of neutral gas transport. When the pump limiter is operated together with other wall components we expect an efficiency of ≅ 5% (2.5 x 10 21 part/s). As a main limiter the efficiency increases to about 10%. (author)

    The very extensive use of limitations in the operational field between protection system and closed-loop controls is an important feature of German understanding of operational safety. The design of limitations is based on very large activities in the computational field but mostly on the high level of the plant-wide own commissioning experience of a turnkey contractor. Limitations combine intelligence features of closed-loop controls with the high availability of protection systems. (orig.)

    Every detector has limitations in terms of solid angle, particular technologies chosen, cracks due to mechanical structure, etc. If all of the presently planned parts of STAR [Solenoidal Tracker At RHIC] were in place, these factors would not seriously limit our ability to exploit the spin physics possible in RHIC. What is of greater concern at the moment is the construction schedule for components such as the Electromagnetic Calorimeters, and the limited funding for various levels of triggers.

This method has been denominated as Modified Secundary Creep and enables to find the collapse loads through a minimization of a functional and a limit process. Given an ideal plastic material it is shown how to determinate the associated secundary creep constitutive equation. Finally, as an application, it is found the limit load in an pressurized von Mises rigid plastic sphere. (Author) [pt

    Full Text Available Resumo Apesar da importância das disputas para os governos estaduais na política brasileira, pouco se sabe a respeito dos fatores que levam às escolhas dos eleitores para esses pleitos. Existem fatores comuns que ajudam a explicar a escolha dos eleitores em todo o país para os governos estaduais? Qual é o peso da avaliação do governo federal e da percepção sobre o desempenho da economia do país nas eleições nas unidades da federação? Candidatos à reeleição ou apoiados pelo governador são beneficiados pela avaliação positiva do governo federal? A preferência partidária importa na hora de escolher os candidatos a governador? Essas são as perguntas que buscamos responder, ainda que de maneira preliminar, neste artigo. Para isso, realizamos análises multivariadas a partir dos dados de nível individual produzidos pelo Estudo Eleitoral Brasileiro (Eseb de 2014. Os resultados indicam que a preferência partidária, assim como nas eleições presidenciais, é importante elemento de escolha nos pleitos para os governos estaduais, e que a disputa entre PT e PSDB no plano nacional acaba por influenciar também o âmbito estadual.

    Highlights: • ReB 2 -type hexagonal OsB 2 powder has been densified by spark plasma sintering. • The sintered OsB 2 contains ∼80 wt.% hexagonal and ∼20 wt.% orthorhombic phases. • The average grain size of the sintered OsB 2 sample was 0.56 ± 0.26 μm. • H = 31 ± 9 GPa and E = 574 ± 112 GPa measured by nanoindentation. - Abstract: The metastable high pressure ReB 2 -type hexagonal OsB 2 bulk ceramics was produced by spark plasma sintering. The phase composition, microstructure, and mechanical behavior of the sintered OsB 2 were studied by X-ray diffraction, optical microscopy, TEM, SEM, EDS, and nanoindentation. The produced ceramics was rather porous and contained a mixture of hexagonal (∼80 wt.%) and orthorhombic (∼20 wt.%) phases as identified by X-ray diffraction and EBSD analysis. Two boron-rich phases, which do not contain Os, were also identified by TEM and SEM/EDS analysis. Nanoindentation measurements yielded a hardness of 31 ± 9 GPa and Young’s modulus of 574 ± 112 GPa, indicating that the material is rather hard and very stiff; however, it is very prone to crack formation and propagation, which is indicative of a very brittle nature of this material. Improvements in the sintering regime are required in order to produce dense, homogeneous and single phase hexagonal OsB 2 bulk ceramics

  7. Re-Os Isotopic Constraints on the Chemical Evolution and Differentiation of the Martian Mantle

    Science.gov (United States)

    Brandon, Alan D.; Walker, Richard J.

    2002-01-01

    The (187)Re-187Os isotopic systematics of SNC meteorites, thought to be from Mars, provide valuable information regarding the chemical processes that affected the Martian mantle, particularly with regard to the relative abundances of highly siderophile elements (HSE). Previously published data (Birck and Allegre 1994, Brandon et al. 2000), and new data obtained since these studies, indicate that the HSE and Os isotopic composition of the Martian mantle was primarily set in its earliest differentiation history. If so, then these meteorites provide key constraints on the processes that lead to variation in HSE observed in not only Mars, but also Earth, the Moon and other rocky bodies in the Solar System. Processes that likely have an effect on the HSE budgets of terrestrial mantles include core formation, magma ocean crystallization, development of juvenile crust, and the addition of a late veneer. Each of these processes will result in different HSE variation and the isotopic composition of mantle materials and mantle derived lavas. Two observations on the SNC data to present provide a framework for which to test the importance of each of these processes. First, the concentrations of Re and Os in SNC meteorites indicate that they are derived from a mantle that has similar concentrations to the Earth's mantle. Such an observation is consistent with a model where a chondritic late veneer replenished the Earth and Martian mantles subsequent to core formation on each planet. Alternative models to explain this observation do exist, but will require additional data to test the limitations of each. Second, Re-Os isotopic results from Brandon et al. (2000) and new data presented here, show that initial yos correlates with variations in the short-lived systems of (182)Hf- (182)W and (142)Sm-142Nd in the SNC meteorites (epsilon(sub W) and epsilon(sub 142Nd)). These systematics require an isolation of mantle reservoirs during the earliest differentiation history of Mars, and

  8. Determination of osmium concentrations and (187)Os/(188)Os of crude oils and source rocks by coupling high-pressure, high-temperature digestion with sparging OsO(4) into a multicollector inductively coupled plasma mass spectrometer.

    The (187)Os/(188)Os ratio that is based on the β(-)-decay of (187)Re to (187)Os (t1/2 = 41.6 billion years) is widely used to investigate petroleum system processes. Despite its broad applicability to studies of hydrocarbon deposits worldwide, a suitable matrix-matched reference material for Os analysis does not exist. In this study, a method that enables Os isotope measurement of crude oil with in-line Os separation and purification from the sample matrix is proposed. The method to analyze Os concentration and (187)Os/(187)Os involves sample digestion under high pressure and high temperature using a high pressure asher (HPA-S, Anton Paar), sparging of volatile osmium tetroxide from the sample solution, and measurements using multicollector inductively coupled plasma mass spectrometry (MC-ICPMS). This methods significantly reduced the total procedural time compared to conventional Carius tube digestion followed by Os separation and purification using solvent extraction, microdistillation and N-TIMS analysis. The method yields Os concentration (28 ± 4 pg g(-1)) and (187)Os/(188)Os (1.62 ± 0.15) of commercially available crude oil reference material NIST 8505 (1 S.D., n = 6). The reference material NIST 8505 is homogeneous with respect to Os concentration at a test portion size of 0.2 g. Therefore, (187)Os/(188)Os composition and Os concentration of NIST 8505 can serve as a matrix-matched reference material for Os analysis. Data quality was assessed by repeated measurements of the USGS shale reference material SCo-1 (sample matrix similar to petroleum source rock) and the widely used Liquid Os Standard solution (LOsSt). The within-laboratory reproducibility of (187)Os/(188)Os for a 5 pg of LOsSt solution, analyzed with this method over a period of 12 months was ∼1.4% (1 S.D., n = 26), respectively.

    Full Text Available O artigo investiga o sentido das relações de troca que envolvem o uso de dinheiro entre os adeptos do candomblé. Essas relações, que ocorrem no âmbito de uma "família de santo", acionam aspectos simbólicos advindos de uma conexão com as coisas sagradas. Estudo aqui a linha tênue em que uma economia do dom ou da graça se confunde constantemente com o mundo dos interesses, assim como estes últimos podem às vezes mobilizar aspectos ligados à graça divina. Tento perceber nessas relações mediadas por dinheiro não apenas os limites imprecisos entre dom e interesse, mas o vasto campo no qual se processam as trocas entre os agentes sociais. Numa percepção mais ampla das questões aqui sugeridas, este trabalho tem como objetivo compreender o sentido social do dinheiro nas relações que constituem a experiência e a prática religiosas.The article investigates the meaning of exchange relations involving the use of money among followers of candomblé. These relations, which unfold within the space of a ‘saint family,’ activate symbolic dimensions that derive from a connection with the sacred. Here I study the border zone where an economy of the gift or grace continually merges with the world of interests, just as the latter sometimes mobilizes aspects linked to divine grace. Examining these relations mediated by money, I try to expose not only the imprecise limits between gift and interest, but the vast field in which the exchanges between social agents are processed. Adopting a wider perspective on the questions raised here, the text aims to comprehend the social meaning of money in the relations that constitute religious experience and practice.

    1982-01-01

    Continuous removal of heat and particles becomes a vital necessity in future steady-state fusion devices. The pump limiter seems to be an attractive concept to combine these two tasks. On ISX, various schemes of pump limiters are being explored with the final goal to furnish the ISX--C device with a pump limiter to handle heat removal and particle control in steady state. The emphasis of the present paper is on pump limiters based on ballistic particle collection. If this concept turns out to be successful in supplying sufficient pumping efficiency, it may be possible to design pump limiters without a leading edge. Analytical calculations of the particle collection efficiency are given for various limiter configurations. Pumping efficiencies of approximately 4--10%, depending on the specific configuration, seem to be feasible and should be sufficient for steady-state operation. Initial experimental results on pump limiter studies in ISX--B confirm the calculated collection efficiencies. By measuring the ion saturation current to the limiter blade and the pressure buildup simultaneously, we found a correlation between the incident particle flux and the pressure rise that agrees well with a simple model

    International Nuclear Information System (INIS)

    Moriarty, Patrick; Honnery, Damon

    2008-01-01

    Most human-caused climate change comes from fossil fuel combustion emissions. To avoid the risk of serious climate change, very recent research suggests that emission reductions will need to be both large and rapidly implemented. We argue that technical solutions-improving energy efficiency, use of renewable and nuclear energy, and carbon capture and sequestration-can only be of minor importance, mainly given the limited time available to take effective climate action. Only curbing energy use, perhaps through 'social efficiency' gains, particularly in the high-energy consumption countries, can provide the rapid emissions reductions needed. The social efficiency approach requires a basic rethinking in how we can satisfy our human needs with low environmental impacts. Large cuts in emissions could then occur rapidly, but only if resistance to such changes can be overcome. Particularly in transport, there are also serious potential conflicts between the technical and the social efficiency approaches, requiring a choice to be made

    2012-01-01

    Existing safety PLCs for using in nuclear power plants operates based on priority based scheduling, in which the highest priority task runs first. This type of scheduling scheme determines processing priorities when multiple requests for processing or when there is a lack of resources available for processing, guaranteeing execution of higher priority tasks. This type of scheduling is prone to exhaustion of resources and continuous preemptions by devices with high priorities, and therefore there is uncertainty every period in terms of smooth running of the overall system. Hence, it is difficult to apply this type of scheme to where deterministic operation is required, such as in nuclear power plant. Also, existing PLCs either have no output logic with regard to devices' redundant selection or it was set in a fixed way, and as a result it was extremely inefficient to use them for redundant systems such as that of a nuclear power plant and their use was limited. Therefore, functional modules that can manage and control all devices need to be developed by improving on the way priorities are assigned among the devices, making it more flexible. A management module should be able to schedule all devices of the system, manage resources, analyze states of the devices, and give warnings in case of abnormal situations, such as device fail or resource scarcity and decide on how to handle it. Also, the management module should have output logic for device redundancy, as well as deterministic processing capabilities, such as with regard to device interrupt events

    Full Text Available In this paper we analyze complexity of time limits we can find especially in regulated processes of public administration. First we review the most popular process modeling languages. There is defined an example scenario based on the current Czech legislature which is then captured in discussed process modeling languages. Analysis shows that the contemporary process modeling languages support capturing of the time limit only partially. This causes troubles to analysts and unnecessary complexity of the models. Upon unsatisfying results of the contemporary process modeling languages we analyze the complexity of the time limits in greater detail and outline lifecycles of a time limit using the multiple dynamic generalizations pattern. As an alternative to the popular process modeling languages there is presented PSD process modeling language, which supports the defined lifecycles of a time limit natively and therefore allows keeping the models simple and easy to understand.

    The concept of the limiter-divertor proposed by Mirnov is extended to a toroidal limiter-divertor (which we call moving toroidal limiter) using the stream of ferromagnetic balls coated with a low Z materials such as plastics, graphite and ceramics. An important advantage of the use of the ferromagnetic materials would be possible soft landing of the balls on a catcher, provided that the temperature of the balls is below Curie point. Moreover, moving toroidal limiter would work as a protector of the first wall not only against the vertical movement of plasma ring but also against the violent inward motion driven by major disruption because the orbit of the ball in the case of moving toroidal limiter distributes over the small major radius side of the toroidal plasma.

    Hexagonal OsB 2 , a theoretically predicted high-pressure phase, has been synthesized for the first time by a mechanochemical method, i.e., high energy ball milling. X-ray diffraction indicated that formation of hexagonal OsB 2 begins after 2.5 h of milling, and the reaction reaches equilibrium after 18 h of milling. Rietveld refinement of the powder data indicated that hexagonal OsB 2 crystallizes in the P63/mmc space group (No. 194) with lattice parameters of a=2.916 Å and c=7.376 Å. Transmission electron microscopy confirmed the appearance of the hexagonal OsB 2 phase after high energy ball milling. in situ X-ray diffraction experiments showed that the phase is stable from −225 °C to 1050 °C. The hexagonal OsB 2 powder was annealed at 1050 °C for 6 days in vacuo to improve crystallinity and remove strain induced during the mechanochemical synthesis. The structure partially converted to the orthorhombic phase (20 wt%) after fast current assisted sintering of hexagonal OsB 2 at 1500 °C for 5 min. Mechanochemical approaches to the synthesis of hard boride materials allow new phases to be produced that cannot be prepared using conventional methods. - Graphical abstract: High resolution transmission electron micrograph of hexagonal OsB 2 nanocrystallite with corresponding fast Fourier transform and simulated diffraction pattern. - Highlights: • Hexagonal OsB 2 has been synthesized for the first time by mechanochemical method. • Hexagonal OsB 2 crystallizes in P63/mmc space group (No. 194), a=2.916 Å and c=7.376 Å. • The hexagonal structure was confirmed by a transmission electron microscope. • No phase transformation was observed after being annealed at 1050 °C for 6 days. • 20 wt% of h-OsB 2 was transformed to o-OsB 2 after being sintered at 1500 °C for 5 min

    1984-05-01

    Recent experiments with a scoop limiter without active internal pumping have been carried out in the PDX tokamak with up to 6MW of auxiliary neutral beam heating. Experiments have also been done with a rotating head pump limiter in the PLT tokamak in conjunction with RF plasma heating. Extensive experiments have been done in the ISX-B tokamak and first experiments have been completed with the ALT-I limiter in TEXTOR. The pump limiter modules in these latter two machines have internal getter pumping. Experiments in ISX-B are with ohmic and auxiliary neutral beam heating. The results in ISX-B and TEXTOR show that active density control and particle removal is achieved with pump limiters. In ISX-B, the boundary layer (or scape-off layer) plasma partially screens the core plasma from gas injection. In both ISX-B and TEXTOR, the pressure internal to the module scales linearly with plasma density but in ISX-B, with neutral beam injection, a nonlinear increase is observed at the highest densities studied. Plasma plugging is the suspected cause. Results from PDX suggest that a region may exist in which core plasma energy confinement improves using a pump limiter during neutral beam injection. Asymmetric radial profiles and an increased edge electron temperature are observed in discharges with improved confinement. The injection of small amounts of neon into ISX-B has more clearly shown an improved electron core energy confinement during neutral beam injection. While carried out with a regular limiter, this Z-mode of operation is ideal for use with pump limiters and should be a way to achieve energy confinement times similar to values for H-mode tokamak plasmas. The implication of all these results for the design of a reactor pump limiter is described

    The use of limiter pumps as the principle plasma exhaust system of a magnetic confinement fusion device promises significant simplification, when compared to previously investigating divertor based systems. Further simplifications, such as the integration of the exhaust system with a radio frequency heating system and with the main reactor shield and structure are investigated below. The integrity of limiters in a reactor environment is threatened by many mechanisms, the most severe of which may be erosion by sputtering. Two novel topolgies are suggested which allow high erosion without limiter failure

    We should clarify several problems for the Re-Os pair to be used as one of the good cosmochronometers. First, since 187 Os is formed and depleted by sequential neutron capture in stars, the effects should be corrected. Second, 187 Os is depleted by the neutron capture process through the excited state at 10 keV. It is very important to find a proper way to correct for the s-process contribution in deducing the age of the Galaxy. In order to correct for the effect mentioned above and to determine the age of the universe, we are planning to measure the neutron capture cross section of the first excited state (E excited =10 keV) of 187 Os, which is one of the key parameters in deducing the age of the Galaxy using the Re-Os cosmochronometer. In order to deduce the cross section we are preparing various detectors using a newly developed experimental method. In the present paper I briefly describe our experimental methods to accurately determine the neutron capture cross section of the first excited state of 187 Os. (author)

  5. Re/Os cosmochronometer: measurement of neutron cross sections

    Mosconi, M.

    2007-01-01

    This experimental work is devoted to the improved assessment of the Re/Os cosmochronometer. The dating technique is based on the decay of 187 Re (t 1/2 =41.2 Gyr) into 187 Os and determines the age of the universe by the time of onset of nucleosynthesis. The nucleosynthesis mechanisms, which are responsible for the 187 Re/ 187 Os pair, provide the possibility to identify the radiogenic fraction of 187 Os exclusively by nuclear physics considerations. Apart from its radiogenic component, 187 Os can be synthesized otherwise only by the s process, which means that this missing fraction can be reliably determined and subtracted by proper s-process modeling. On the other hand, 187 Re is almost completely produced by the r process. The only information needed for the interpretation as a cosmic clock is the production rate of 187 Re as a function of time. The accuracy of the s-process calculations that are needed to determine the nucleosynthetic abundance of 187 Os depends on the quality of the neutron capture cross sections averaged over the thermal neutron spectrum at the s-process sites. Laboratory measurements of these cross sections have to be corrected for the effect of nuclear levels, which can be significantly populated at the high stellar temperatures during the s process. The neutron capture cross sections of 186 Os, 187 Os and 188 Os have been measured at the CERN n TOF facility in the range between 0.7 eV and 1 MeV. From these data, Maxwellian averaged cross sections have been determined for thermal energies from 5 to 100 keV with an accuracy around 4%, 3%, and 5% for 186 Os, 187 Os, and 188 Os, respectively. Since, the first excited state in 187 Os occurs at 9.75 keV, the cross section of this isotope requires a substantial correction for thermal population of low lying nuclear levels. This effect has been evaluated on the basis of resonance data derived in the (n, γ) experiments and by an improved measurements of the inelastic scattering cross section for

  14. Limit lines for risk

    International Nuclear Information System (INIS)

    Cox, D.C.; Baybutt, P.

    1982-01-01

    Approaches to the regulation of risk from technological systems, such as nuclear power plants or chemical process plants, in which potential accidents may result in a broad range of adverse consequences must take into account several different aspects of risk. These include overall or average risk, accidents posing high relative risks, the rate at which accident probability decreases with increasing accident consequences, and the impact of high frequency, low consequence accidents. A hypothetical complementary cumulative distribution function (CCDF), with appropriately chosen parametric form, meets all these requirements. The Farmer limit line, by contrast, places limits on the risks due to individual accident sequences, and cannot adequately account for overall risk. This reduces its usefulness as a regulatory tool. In practice, the CCDF is used in the Canadian nuclear licensing process, while the Farmer limit line approach, supplemented by separate qualitative limits on overall risk, is employed in the United Kingdom

    This note presents a direct adjustment of the estimative prediction limit to reduce the coverage error from a target value to third-order accuracy. The adjustment is asymptotically equivalent to those of Barndorff-Nielsen & Cox (1994, 1996) and Vidoni (1998). It has a simpler form with a plug-in estimator of the coverage probability of the estimative limit at the target value. Copyright 2007, Oxford University Press.

    Full Text Available We examined how different types of reproductive limitations — functional (schizoid personality disorder and schizophrenia, physical (malnutrition, and sexual (bisexuality and homosexuality — influenced altruistic intentions toward hypothetical target individuals of differing degrees of relatedness (r = 0, .25, and .50. Participants were 312 undergraduate students who completed a questionnaire on altruism toward hypothetical friends, half-siblings, and siblings with these different types of reproductive limitations. Genetic relatedness and reproductive limitations did not influence altruistic decision-making when the cost of altruism was low but did as the cost of altruism increased, with participants being more likely to help a sibling over a half-sibling and a half-sibling over a friend. Participants also indicated they were more likely to help a healthy (control person over people with a reproductive limitation. Of the three types of reproductive limitations, functional limitations had the strongest effect on altruistic decision-making, indicating that people were less likely to help those who exhibit abnormal social behavior.

    In this paper is investigated the yield of Magnetic Resonance Imaging (MRI) in hind foot conditions, particularly the os trigonum syndrome, which are very difficult to diagnose clinically. 7 consecutive patients were examined. They were complaining of hind foot pain for more than 4 months (male:female=1:6; age range 16-22 years, average 18.6). Three patients practiced competitive sports and 4 ballet. It was performed conventional radiography (orthogonal projections) and then MRI with a 0.5 T superconductive unit with surface coils; MR images were acquired with T1-weighted spin-echo (SE), T2-weighted gradient-echo (GRE), and fast inversion recovery (FIR) fat-suppressed sequences with 4 mm thickness and 0 mm gap. In 2 cases the os trigonum had irregular margins with subchondral sclerosis and widened synchondrosis. In 3 patients it was found flessor hallucis longus tenosynovitis, likely caused by tendon compression and displacement within its sheath; there were neither os trigonum marrow edema nor synchondrosis widening. One patient had os trigonum hypertrophy, mild synchondrosis widening and marrow edema, in the os trigonum and the posterior aspect of talus. One patient had the os trigonum, but no signs referable to the os trigonum syndrome. In the posterior impingement syndrome, the objective is to show inflammatory changes in the posterior capsule of the ankle joint, adjacent ligaments, tendons and chondrosynovial surface. MR provides important information on soft tissues involvement, synovial reaction, chondral and subchondral bone injuries and the association of flexor hallucis longus synovitis, if present. MRI also yields detailed information for correct therapeutic approach. In conclusion, MRI appears to be the technique of choice, after conventional radiography, thanks to its non invasiveness, multi planarity, and high spatial and contrast resolution [it

    2007-06-15

    A novel chitosan/PVI-Os(polyvinylimidazole-Os)/CNT(carbon nanotube)/LOD (lactate oxidase) network nanocomposite was constructed on gold electrode for detection of lactate. The composite was nanoengineered by selected matched material components and optimized composition ratio to produce a superior lactate sensor. Positively charged chitosan and PVI-Os were used as the matrix and the mediator to immobilize the negatively charged LOD and to enhance the electron transfer, respectively. CNTs were introduced as the essential component in the composite for the network nanostructure. FESEM (field emission scan electron microscopy) and electrochemical characterization demonstrated that CNT behaved as a cross-linker to network PVI and chitosan due to its nanoscaled and negative charged nature. This significantly improved the conductivity, stability and electroactivity for detection of lactate. The standard deviation of the sensor without CNT in the composite was greatly reduced from 19.6 to 4.9% by addition of CNTs. With optimized conditions the sensitivity and detection limit of the lactate sensor was 19.7 microA mM(-1)cm(-2) and 5 microM, respectively. The sensitivity was remarkably improved in comparison to the newly reported values of 0.15-3.85 microA mM(-1)cm(-2). This novel nanoengineering approach for selecting matched components to form a network nanostructure could be extended to other enzyme biosensors, and to have broad potential applications in diagnostics, life science and food analysis.

  11. Force Limit System

    Science.gov (United States)

    Pawlik, Ralph; Krause, David; Bremenour, Frank

    2011-01-01

    The Force Limit System (FLS) was developed to protect test specimens from inadvertent overload. The load limit value is fully adjustable by the operator and works independently of the test system control as a mechanical (non-electrical) device. When a test specimen is loaded via an electromechanical or hydraulic test system, a chance of an overload condition exists. An overload applied to a specimen could result in irreparable damage to the specimen and/or fixturing. The FLS restricts the maximum load that an actuator can apply to a test specimen. When testing limited-run test articles or using very expensive fixtures, the use of such a device is highly recommended. Test setups typically use electronic peak protection, which can be the source of overload due to malfunctioning components or the inability to react quickly enough to load spikes. The FLS works independently of the electronic overload protection.

    1986-01-01

    Over the past two decades the theory of limit cycles, especially for quadratic differential systems, has progressed dramatically in China as well as in other countries. This monograph, updating the 1964 first edition, includes these recent developments, as revised by eight of the author's colleagues in their own areas of expertise. The first part of the book deals with limit cycles of general plane stationary systems, including their existence, nonexistence, stability, and uniqueness. The second section discusses the global topological structure of limit cycles and phase-portraits of quadratic systems. Finally, the last section collects important results that could not be included under the subject matter of the previous two sections or that have appeared in the literature very recently. The book as a whole serves as a reference for college seniors, graduate students, and researchers in mathematics and physics.

  13. Peroneus longus tears associated with pathology of the os peroneum.

    Stockton, Kristopher G; Brodsky, James W

    2014-04-01

    There is a range of different types of tears and pathology of the peroneal tendons. One of the least common types is the tear of the peroneus longus associated with fracture, enlargement, or entrapment at the cuboid tunnel of the os peroneum. The purpose of this study was to evaluate the pathologic patterns of these uncommon peroneal tendon tears, to review the treatment, and to report the patient outcomes following treatment with excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. A 5-year retrospective review of all patients with peroneal tendon tears identified 12 patients operatively treated for peroneus longus tendon tears with associated pathology of the os peroneum, and in whom there was a viable peroneus brevis. All patients were treated with an operative procedure consisting of excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. Mean age was 51.5 (range, 33 to 73) years, including 7 males and 5 females. Operative and radiographic records were reviewed to characterize the nature of the peroneus longus tears and associated pathology. Preoperative and postoperative AOFAS hindfoot, SF-36 questionnaires, and Visual Analog Scale (VAS) pain scores were compiled and patient records were reviewed for complications. Mean follow-up after surgery was 63.3 (range, 12 to 114) months. All of the patients had an os peroneum associated with a complex, irreparable tear of the peroneus longus tendon. The peroneus longus was typically enlarged, fibrotic, and adhered to the surrounding tissues. In 8 patients, the peroneus longus tendon tear was associated with a fracture of the os peroneum, and in 4 patients with an enlarged and entrapped os peroneum which prevented movement at the cuboid tunnel. Of the 12 patients, 9 had partial tears of the peroneus brevis, which were treated with debridement and suture repair. AOFAS hindfoot scores increased from a preoperative mean of 61

    Full Text Available O processo de urbanização nas pequenas cidades da Amazônia, nas últimas décadas, tem transformado o cenário urbano e também o rural, os quais foram reestruturados e perderam suas características típicas. Apesar de existirem cidades fortemente dependentes dos recursos das florestas, há o surgimento de cidades que se desvincularam dessas atividades rurais, tornando-se conectadas ao mercado global por meio da indústria. O município de Barcarena, no Pará, é um exemplo desse processo e, apesar de sua economiaestar voltada para a atividade industrial, possui uma população rural que se sobrepõe à população urbana. Nesse aspecto, o presente artigo objetiva compreender a reestruturação urbana desse município a partir da instalação de um complexo industrial e dos paradoxos urbanos que surgiram a partir desse processo. Para o seu desenvolvimento, foram utilizados dados coletados por meio de formulários aplicados aos domicílios urbanos, dados censitários e informações coletadas no município. A pesquisa demonstra incoerência de dados sobre urbanidade, questiona as proposições do Instituto Brasileiro de Geografia e Estatística (IBGE e conclui que Barcarena ainda é uma “cidade da floresta”, por conservar uma cultura e economia fortemente relacionada à floresta, e que Vila dos Cabanos é uma “cidade na floresta”, por apresentar funções logísticas fortemente ligadas ao exterior e desvinculadas da floresta.

    Evans, Lyndon R

    1992-01-01

    The three colliders operated to date have taught us a great deal about the behaviour of both bunched and debunched beams in storage rings. The main luminosity limitations are now well enough understood that most of them can be stronglu attenuated or eliminated by approriate design precautions. Experience with the beam-beam interaction in both the SPS and the Tevatron allow us to predict the performance of the new generation of colliders with some degree of confidence. One of the main challenges that the accelerator physicist faces is the problem of the dynamic aperture limitations due to the lower field quality expected, imposed by economic and other constraints.

    The SLC Damping Ring kicker magnets requires a fast magnetic field rise time of 58 nsec, a peak field of 800 gauss, a pulse amplitude stability of 0.01%, and a reasonable operational lifetime. The original kicker magnets designed by SLAC and at Fermi were not able to fulfill the SLC kicker requirements. Extensive studies were conducted to determine the limitation in the magnets, response of the ferrite in kicker magnet, and the modifications needed to improve the kicker magnet performance.

    Full Text Available Introduction Os odontoideum (OO is a form of odontoid anomaly presented by a separate ossicle with a smooth, sclerotic border not fused with C2 body. The current paper reports a boy with irreducible displaced os odontoideum with severe neurologic deficit after a minor trauma. Case Presentation A 16-year-old boy admitted in the center due to neck pain and torticollis with neurologic deficit. He had a history of multiple minor traumas. Advanced imaging assessment demonstrated displaced os odontoideum with minimal space available for cord (SAC and myelomalacia. After unsuccessful closed reduction a 2-stage operation was planned: first, the anterior transoral release and odontoid resection with subsequent halo-traction and second, the posterior atlanto-axial instrumented fusion with bilateral C1 hook and C2 pedicular screws. Conclusions Congenital anomalies of the odontoid are associated with C1-C2 instability that can be subluxated or dislocated with minor trauma and cause permanent neurologic deficit or even death. When acute cervical spine trauma is imaged, os odontoideum should be distinguished from an acute dens fracture with a multimodality imaging approach including computed tomography (CT, magnetic resonance imaging (MRI and radiography. Here is the report of a rare case with irreducible displaced os odontiodeum treated him with anterior release, odontoid resection and posterior C1-C2 instrumented fusion.

    Highlights: • fcc- and hcp-Ir-Os alloys were prepared from single-source precursors. • Their atomic volumes measured at ambient conditions using powder X-ray diffraction follow nearly linear dependence. • Compressibility of alloys have been studied up to 30 GPa at room temperature in diamond anvil cells. • Their bulk moduli increase with increasing osmium content. - Abstract: Several fcc- and hcp-structured Ir-Os alloys were prepared from single-source precursors in hydrogen atmosphere at 873 K. Their atomic volumes measured at ambient conditions using powder X-ray diffraction follow nearly linear dependence as a function of composition. Alloys have been studied up to 30 GPa at room temperature by means of synchrotron-based X-ray powder diffraction in diamond anvil cells. Their bulk moduli increase with increasing osmium content and show a deviation from linearity. Bulk modulus of hcp-Ir 0.20 Os 0.80 is identical to that of pure Os (411 GPa) within experimental errors. Peculiarities on fcc-Ir 0.80 Os 0.20 compressibility curve indicate possible changes of its electronic properties at ∼20 GPa

  2. Gas-phase chemistry of Mo, Ru, W, and Os metal carbonyl complexes

    Wang, Y.; Qin, Z.; Fan, F.L.

    2014-01-01

    Metal carbonyl complexes were used for studying the gas-phase chemical behavior of Mo, Ru, W and Os isotopes with an on-line low temperature isothermal gas chromatography apparatus. Short-lived Mo and Ru isotopes were produced by a 252 Cf spontaneous fission source. Short-lived nuclides of W and Os were produced using the heavy ion reactions 19 F + 159 Tb and 165 Ho, respectively. Short-lived products were thermalized in a recoil chamber filled with a gas mixture of helium and carbon monoxide. The carbonyls formed were then transported through capillaries to an isothermal chromatography column for study of the adsorption behavior as a function of temperature. On-line isothermal chromatography (IC) experiments on Teflon (PTFE) and quartz surfaces showed that short-lived isotopes of the listed elements can form carbonyl complexes which are very volatile and interact most likely in physical sorption processes. Deduced adsorption enthalpies of Mo and Ru carbonyls were -38 ± 2 kJ/mol and -36 ± 2 kJ/mol, respectively. These values are in good agreement with literature data, partly obtained with different chromatographic techniques. A validation of the applied Monte Carlo model to deduce adsorption enthalpies with Mo isotopes of different half-lives proved the validity of the underlying adsorption model. The investigations using a gas-jet system coupled to a heavy ion accelerator without any preseparator clearly showed the limitations of the approach. The He and CO gas mixture, which was directly added into the chamber, will result in decomposition of CO gas and produce some aerosol particles. After the experiment of 173 W and 179 Os in the heavy ion experiments, the Teflon column was covered by a yellowish deposit; the adsorption enthalpy of W and Os carbonyls could therefore not be properly deduced using Monte Carlo simulations.

  8. OsNF-YC2 and OsNF-YC4 proteins inhibit flowering under long-day conditions in rice

    KAUST Repository

    2015-11-05

    OsNF-YC2 and OsNF-YC4 proteins regulate the photoperiodic flowering response through the modulation of three flowering-time genes ( Ehd1, Hd3a , and RFT1 ) in rice. Plant NUCLEAR FACTOR Y (NF-Y) transcription factors control numerous developmental processes by forming heterotrimeric complexes, but little is known about their roles in flowering in rice. In this study, it is shown that some subunits of OsNF-YB and OsNF-YC interact with each other, and among them, OsNF-YC2 and OsNF-YC4 proteins regulate the photoperiodic flowering response of rice. Protein interaction studies showed that the physical interactions occurred between the three OsNF-YC proteins (OsNF-YC2, OsNF-YC4 and OsNF-YC6) and three OsNF-YB proteins (OsNF-YB8, OsNF-YB10 and OsNF-YB11). Repression and overexpression of the OsNF-YC2 and OsNF-YC4 genes revealed that they act as inhibitors of flowering only under long-day (LD) conditions. Overexpression of OsNF-YC6, however, promoted flowering only under LD conditions, suggesting it could function as a flowering promoter. These phenotypes correlated with the changes in the expression of three rice flowering-time genes [Early heading date 1 (Ehd1), Heading date 3a (Hd3a) and RICE FLOWERING LOCUS T1 (RFT1)]. The diurnal and tissue-specific expression patterns of the subsets of OsNF-YB and OsNF-YC genes were similar to those of CCT domain encoding genes such as OsCO3, Heading date 1 (Hd1) and Ghd7. We propose that OsNF-YC2 and OsNF-YC4 proteins regulate the photoperiodic flowering response by interacting directly with OsNF-YB8, OsNF-YB10 or OsNF-YB11 proteins in rice.

    The os trigonum is an accessory bone of the foot found in 7% of the normal adult population. It is located at the posterolateral projection of the talus, and can occasionally give rise to symptoms of acute and chronic unexplained ankle pain. We report three patients, one with acute fracture and two with chronic ankle symptoms. Technetium 99 methylene diphosphonate showed intense focal uptake at the posterior talus pointing to the os trigonum as the site of symptoms. It was excised in two patients with complete relief. The third went on to develop an asymptomatic nonunion. We recommend bone scanning as a procedure that is helpful in delineating obscure pain in the ankle that may be due to chronic irritative nonunion of the os trigonum

  14. Limitations on blanket performance

    International Nuclear Information System (INIS)

    Malang, S.

    1999-01-01

    The limitations on the performance of breeding blankets in a fusion power plant are evaluated. The breeding blankets will be key components of a plant and their limitations with regard to power density, thermal efficiency and lifetime could determine to a large degree the attractiveness of a power plant. The performance of two rather well known blanket concepts under development in the frame of the European Blanket Programme is assessed and their limitations are compared with more advanced (and more speculative) concepts. An important issue is the question of which material (structure, breeder, multiplier, coatings) will limit the performance and what improvement would be possible with a 'better' structural material. This evaluation is based on the premise that the performance of the power plant will be limited by the blankets (including first wall) and not by other components, e.g. divertors, or the plasma itself. However, the justness of this premise remains to be seen. It is shown that the different blanket concepts cover a large range of allowable power densities and achievable thermal efficiencies, and it is concluded that there is a high incentive to go for better performance in spite of possibly higher blanket cost. However, such high performance blankets are usually based on materials and technologies not yet developed and there is a rather high risk that the development could fail. Therefore, it is explained that a part of the development effort should be devoted to concepts where the materials and technologies are more or less in hand in order to ensure that blankets for a DEMO reactor can be developed and tested in a given time frame.

    2008-04-01

    Full Text Available A partir de um estudo de caso centrado em uma organização que edita uma revista vendida por pessoas "sem teto" na cidade de Buenos Aires, me interrogo sobre os usos sociais do dinheiro em circuitos filantrópicos. Ao seguir a polêmica entre dinheiro e dom, que está no centro das discussões da antropologia e da sociologia, enfoco duas questões: a o papel do dinheiro para demarcar os limites entre as "transações mercantis" e as "circulações de dons"; b a relação entre dinheiro e moral. O trabalho de campo consistiu em uma etnografia das transações entre os vendedores e os compradores desta publicação.Based on a case study of an organization responsible for publishing a magazine sold to ‘homeless’ people in Buenos Aires, I examine the social uses of money in philanthropic circles. Turning to the polemic between money and gift at the centre of discussions in anthropology and sociology, I focus on two questions: a the role of money in demarcating the limits between ‘market transactions’ and ‘gift circulations’; b the relation between money and morality. Fieldwork involved an ethnographic study of the transactions between the sellers and buyers of this publication.

    The aim of this study is to determine the feasibility of an Apple iOS-based automated hearing testing application and to compare its accuracy with conventional audiometry. Prospective diagnostic study. Setting Academic medical center. An iOS-based software application was developed to perform automated pure-tone hearing testing on the iPhone, iPod touch, and iPad. To assess for device variations and compatibility, preliminary work was performed to compare the standardized sound output (dB) of various Apple device and headset combinations. Forty-two subjects underwent automated iOS-based hearing testing in a sound booth, automated iOS-based hearing testing in a quiet room, and conventional manual audiometry. The maximum difference in sound intensity between various Apple device and headset combinations was 4 dB. On average, 96% (95% confidence interval [CI], 91%-100%) of the threshold values obtained using the automated test in a sound booth were within 10 dB of the corresponding threshold values obtained using conventional audiometry. When the automated test was performed in a quiet room, 94% (95% CI, 87%-100%) of the threshold values were within 10 dB of the threshold values obtained using conventional audiometry. Under standardized testing conditions, 90% of the subjects preferred iOS-based audiometry as opposed to conventional audiometry. Apple iOS-based devices provide a platform for automated air conduction audiometry without requiring extra equipment and yield hearing test results that approach those of conventional audiometry.

    Full Text Available Após mais de trinta anos de reforma e abertura, a China enfrenta desafios cada vez maiores para manter seu desenvolvimento sustentável e para definir sua posição no cenário mundial. O resto do mundo, por sua vez, está adaptando suas estratégias diante da ascensão chinesa. Assim, a China encontra-se perante a necessidade de construir uma relação favorável com o exterior. É nesse contexto que o país avança uma estratégia de desenvolvimento pacífico e uma visão de mundo harmoniosa com o objetivo de assegurar a seus parceiros suas boas intenções. Nesse processo, a China valoriza a cooperação entre países emergentes, notadamente com os países BRICS. Comparado ao modelo desigual de interação do G8+5, os BRICS oferecem uma plataforma independente para potências emergentes trabalharem como um grupo no âmbito do atual sistema internacional. A China considera os países BRICS parceiros estratégicos para o desenvolvimento, pares com opiniões compartilhadas sobre os assuntos mundiais e novas forças em prol da reforma do sistema internacional. Conquanto aposte no futuro dos BRICS, permanece consciente das diferenças e cautelas existentes entre os membros. Como sua grande estratégia é de ascensão pacífica e construtiva, a China entende os BRICS como uma força internacional progressiva e cooperativa, e não como uma força coletiva de bloqueio.

    2001-01-01

    Shoulder impingement syndrome is caused by repeated mechanical trauma to the rotator cuff due to encroachment of the coracoacromial ligament; in most cases, it is a primary lesion. Os acromiale, an anatomic variant of the shoulder structures, is one of the predisposing factors for the development of this entity. We present a case of os acromiale complicated by complete rupture of the tendon of the supraspinatus muscle and luxation of the long head of the biceps tendon. We stress the importance of magnetic resonance in the study of this anatomic variant and in the detection of complications or associated lesions. (Author) 10 refs

  14. Age Limit of Pediatrics.

    Science.gov (United States)

    Hardin, Amy Peykoff; Hackell, Jesse M

    2017-09-01

    Pediatrics is a multifaceted specialty that encompasses children's physical, psychosocial, developmental, and mental health. Pediatric care may begin periconceptionally and continues through gestation, infancy, childhood, adolescence, and young adulthood. Although adolescence and young adulthood are recognizable phases of life, an upper age limit is not easily demarcated and varies depending on the individual patient. The establishment of arbitrary age limits on pediatric care by health care providers should be discouraged. The decision to continue care with a pediatrician or pediatric medical or surgical subspecialist should be made solely by the patient (and family, when appropriate) and the physician and must take into account the physical and psychosocial needs of the patient and the abilities of the pediatric provider to meet these needs.

  15. FTU pump limiter

    1989-01-01

    The control of the refuelling and recycling of the plasma is crucial in providing enhanced performances in tokamaks and steady-state operation in future reactors. In this paper, we report details of the design and analysis for the pump limiter to be incorporated into the FTU tokamak. The FTU, presently under commissioning, is a compact high field (B=8T), medium high density, circular cross section machine with small accesses. The dimensions of the equatorial port (width 8 cm) would reduce the length of the entrance throat to a few centimeters, which is unacceptable for efficient particle trapping. We have, therefore, designed a rotating blade of the pump limiter head that, in the working position, extends in the toroidal direction inside the vacuum chamber. (author) 8 refs., 4 figs

    Witcher, Joseph Brandon; Bredemann, Michael V.

    2017-09-05

    An apparatus comprising a steady state sensing circuit, a switching circuit, and a detection circuit. The steady state sensing circuit is connected to a first, a second and a third node. The first node is connected to a first device, the second node is connected to a second device, and the steady state sensing circuit causes a scaled current to flow at the third node. The scaled current is proportional to a voltage difference between the first and second node. The switching circuit limits an amount of current that flows between the first and second device. The detection circuit is connected to the third node and the switching circuit. The detection circuit monitors the scaled current at the third node and controls the switching circuit to limit the amount of the current that flows between the first and second device when the scaled current is greater than a desired level.

    The uncertainties associated with performing Instrumental Neutron Activation Analysis (INAA) are discussed in relation to their category. The Comite International de Poids et Mesure (CIPM) distinguishes between uncertainties according to how their contribution to the overall uncertainty is evaluated. INAA is a potentially definitive method, if all sources of uncertainty can be accounted for. The limitation of the method is reached when uncertainties, which cannot be accounted for, assume significance, and the method cannot be brought in statistical control. (orig.)

    Bekhaled, M.

    1987-01-01

    This patent describes an AC current limiter for a power transport line including a power supply circuit and feeding a load circuit via an overload circuit-breaker member. The limiter comprises a transformer having a primary winding connected in series between the power supply circuit and the load circuit and at least one secondary winding of superconductor material contained in a cryogenic enclosure and short-circuited on itself. The leakage reactance of the transformer as seen from the primary winding is low, and the resistance of the at least one secondary winding when in the non-superconducting state and as seen from the primary is much greater than the nominal impedance of the transformer. The improvement whereby the at least one secondary winding of the transformer comprises an active winding in association with a set of auxiliary windings. The set of auxiliary windings is constituted by an even number of series-connected auxiliary windings wound in opposite directions, with the total number of turns in one direction being equal to the total number of turns in the opposite direction, and with the thermal capacity of the secondary winding as a whole being sufficiently high to limit the expansion thereof to a value which remains small during the time it takes the circuit-breaking member to operate

  4. Os limites da participação dos trabalhadores nos ganhos das empresas The limits of workers' share in profits

    Directory of Open Access Journals (Sweden)

    Francisco Paulo Cipolla

    2007-12-01

    Full Text Available This article argues that workers’ share in profits are actually a share in extra surplus value obtained by means of more intensified labor. Cost reductions obtained by means of more intensified lean production methods cause wages to represent a smaller fraction of the product of a working day when measured at market value. The increased market rate of surplus value is the basis for workers’ shares in profits. However, as competition continuously levels out such advantages, the share in profits becomes dependent on a continuous strive to reducing costs and intensifying labor.

    Full Text Available Butyltin compounds were investigated in surface sediments from 17 stations in Todos os Santos Bay. Analytical conditions for organotin determination in marine sediments were optimized for GC with pulsed flame photometric detection. Detection limits were: 5.4 µg kg-1 for TBT; 0.2 µg kg-1 for DBT; and 2.1 µg kg-1 for MBT, using a 610-nm filter. In general, TBT concentrations were low and in the range of

    limit despite the oxic to slightly anoxic conditions in the sediments. The presence of paint particles in the sediments and degradation in the water column during resuspension events followed by removal of the more soluble DBT and MBT may explain these observations.

    The nitrate (NO3-) transporter has been selected as an important gene maker in the process of environmental adoption in rice cultivars. In this work, we transferred another native OsNAR2.1 promoter with driving OsNAR2.1 gene into rice plants. The transgenic lines with exogenous pOsNAR2.1:OsNAR2.1 constructs showed enhanced OsNAR2.1 expression level, compared with wild type (WT), and 15 N influx in roots increased 21%-32% in response to 0.2 mm and 2.5 mm 15NO3- and 1.25 mm 15 NH 4 15 NO 3 . Under these three N conditions, the biomass of the pOsNAR2.1:OsNAR2.1 transgenic lines increased 143%, 129% and 51%, and total N content increased 161%, 242% and 69%, respectively, compared to WT. Furthermore in field experiments we found the grain yield, agricultural nitrogen use efficiency (ANUE), and dry matter transfer of pOsNAR2.1:OsNAR2.1 plants increased by about 21%, 22% and 21%, compared to WT. We also compared the phenotypes of pOsNAR2.1:OsNAR2.1 and pOsNAR2.1:OsNRT2.1 transgenic lines in the field, found that postanthesis N uptake differed significantly between them, and in comparison with the WT. Postanthesis N uptake (PANU) increased approximately 39% and 85%, in the pOsNAR2.1:OsNAR2.1 and pOsNAR2.1:OsNRT2.1 transgenic lines, respectively, possibly because OsNRT2.1 expression was less in the pOsNAR2.1:OsNAR2.1 lines than in the pOsNAR2.1:OsNRT2.1 lines during the late growth stage. These results show that rice NO 3 - uptake, yield and NUE were improved by increased OsNAR2.1 expression via its native promoter. © 2017 The Authors.

Embora pareça uma postura honesta e proativa, não se conhecem 05 seus efeitos sobre o comportamento do consumidor. Como este percebe essas mensagens? Quais as suas Intenções em relação a essas empresas que fizeram o recall? O uso de citações de fomecedores na mensagem faz alguma diferença? A fim de Investigar essas questões, foi realizada uma pesquisa com 204 consumidores, dos quais 142 (70% possuiam automóvel. Os resultados mostraram que somente a avaliação da imagem apresentou diferença significativa entre os grupos, tendo sido negativa no grupo com referência ao fornecedor e positiva no grupo sem referência, principalmente para os consumidores de alto envolvimento com o produto. As implicações gerendais e recomendações para novas pesquisas são também apresentadas.

  3. Strategic arms limitation

    Science.gov (United States)

    Allen Greb, G.; Johnson, Gerald W.

    1983-10-01

    Following World War II, American scientists and politicians proposed in the Baruch plan a radical solution to the problem of nuclear weapons: to eliminate them forever under the auspices of an international nuclear development authority. The Soviets, who as yet did not possess the bomb, rejected this plan. Another approach suggested by Secretary of War Henry Stimson to negotiate directly with the Soviet Union was not accepted by the American leadership. These initial arms limitation failures both reflected and exacerbated the hostile political relationship of the superpowers in the 1950s and 1960s. Since 1969, the more modest focus of the Soviet-American arms control process has been on limiting the numbers and sizes of both defensive and offensive strategic systems. The format for this effort has been the Strategic Arms Limitatins Talks (Salt) and more recently the Strategic Arms Reduction Talks (START). Both sides came to these negotiations convinced that nuclear arsenals had grown so large that some for of mutual restraint was needed. Although the SALT/START process has been slow and ponderous, it has produced several concrete the agreements and collateral benefits. The 1972 ABM Treaty restricts the deployment of ballistic missile defense systems, the 1972 Interim Agreement places a quantitative freeze on each side's land based and sea based strategic launchers, and the as yet unratified 1979 SALT II Treaty sets numerical limits on all offensive strategic systems and sublimits on MIRVed systems. Collateral benefits include improved verification procedures, working definitions and counting rules, and permanent bureaucratic apparatus which enhance stability and increase the chances for achieving additional agreements.

  4. Beta limits for ETF

    International Nuclear Information System (INIS)

    Helton, F.J.; Miller, R.L.

    1982-01-01

    ETF (Engineering Test Facility) one-dimensional transport simulations indicate that a volume-average beta of 4% is required for ignition. It is therefore important that theoretical beta limits, determined by requiring equilibria to be stable to all ideal modes, exceed 4%. This paper documents an ideal MHD analysis wherein it is shown that, with appropriate plasma cross-sectional shape and current profile optimization, operation near 5% is possible. The critical beta value, however, depends on the functional form used for ff', which suggests that higher critical betas could be achieved by directly optimizing the safety factor profile. (author)

  5. Limitations of Boltzmann's principle

    International Nuclear Information System (INIS)

    Lavenda, B.H.

    1995-01-01

    The usual form of Boltzmann's principle assures that maximum entropy, or entropy reduction, occurs with maximum probability, implying a unimodal distribution. Boltzmann's principle cannot be applied to nonunimodal distributions, like the arcsine law, because the entropy may be concave only over a limited portion of the interval. The method of subordination shows that the arcsine distribution corresponds to a process with a single degree of freedom, thereby confirming the invalidation of Boltzmann's principle. The fractalization of time leads to a new distribution in which arcsine and Cauchy distributions can coexist simultaneously for nonintegral degrees of freedom between √2 and 2

    A fault current limiter (FCL) includes a series of high permeability posts for collectively define a core for the FCL. A DC coil, for the purposes of saturating a portion of the high permeability posts, surrounds the complete structure outside of an enclosure in the form of a vessel. The vessel contains a dielectric insulation medium. AC coils, for transporting AC current, are wound on insulating formers and electrically interconnected to each other in a manner such that the senses of the magnetic field produced by each AC coil in the corresponding high permeability core are opposing. There are insulation barriers between phases to improve dielectric withstand properties of the dielectric medium.

  7. Dose. Detriment. Limit assessment

    2015-01-01

    One goal of radiation protection is the limitation of stochastic effects due to radiation exposure. The probability of occurrence of a radiation induced stochastic effect, however, is only one of several other parameters which determine the radiation detriment. Though the ICRP-concept of detriment is a quantitative definition, the kind of detriment weighting includes somewhat subjective elements. In this sense, the detriment-concept of ICRP represents already at the stage of effective dose a kind of assessment. Thus, by comparing radiation protection standards and concepts interconvertible or with those of environment or occupational protection one should be aware of the possibly different principles of detriment assessment.

  11. Limits to biofuels

    2013-06-01

    Full Text Available Biofuel production is dependent upon agriculture and forestry systems, and the expectations of future biofuel potential are high. A study of the global food production and biofuel production from edible crops implies that biofuel produced from edible parts of crops lead to a global deficit of food. This is rather well known, which is why there is a strong urge to develop biofuel systems that make use of residues or products from forest to eliminate competition with food production. However, biofuel from agro-residues still depend upon the crop production system, and there are many parameters to deal with in order to investigate the sustainability of biofuel production. There is a theoretical limit to how much biofuel can be achieved globally from agro-residues and this amounts to approximately one third of todays’ use of fossil fuels in the transport sector. In reality this theoretical potential may be eliminated by the energy use in the biomass-conversion technologies and production systems, depending on what type of assessment method is used. By surveying existing studies on biofuel conversion the theoretical limit of biofuels from 2010 years’ agricultural production was found to be either non-existent due to energy consumption in the conversion process, or up to 2–6000TWh (biogas from residues and waste and ethanol from woody biomass in the more optimistic cases.

    Traveler attended the Dahlem Research Conference organized by the Freien Universitat, Berlin. The subject of the conference was Limiting the Greenhouse Effect: Options for Controlling Atmospheric CO{sub 2} Accumulation. Like all Dahlem workshops, this was a meeting of scientific experts, although the disciplines represented were broader than usual, ranging across anthropology, economics, international relations, forestry, engineering, and atmospheric chemistry. Participation by scientists from developing countries was limited. The conference was divided into four multidisciplinary working groups. Traveler acted as moderator for Group 3 which examined the question What knowledge is required to tackle the principal social and institutional barriers to reducing CO{sub 2} emissions'' The working rapporteur was Jesse Ausubel of Rockefeller University. Other working groups examined the economic costs, benefits, and technical feasibility of options to reduce emissions per unit of energy service; the options for reducing energy use per unit of GNP; and the significant of linkage between strategies to reduce CO{sub 2} emissions and other goals. Draft reports of the working groups are appended. Overall, the conference identified a number of important research needs in all four areas. It may prove particularly important in bringing the social and institutional research needs relevant to climate change closer to the forefront of the scientific and policy communities than hitherto.

  14. Limitations of inclusive fitness.

    Allen, Benjamin; Nowak, Martin A; Wilson, Edward O

    2013-12-10

    Until recently, inclusive fitness has been widely accepted as a general method to explain the evolution of social behavior. Affirming and expanding earlier criticism, we demonstrate that inclusive fitness is instead a limited concept, which exists only for a small subset of evolutionary processes. Inclusive fitness assumes that personal fitness is the sum of additive components caused by individual actions. This assumption does not hold for the majority of evolutionary processes or scenarios. To sidestep this limitation, inclusive fitness theorists have proposed a method using linear regression. On the basis of this method, it is claimed that inclusive fitness theory (i) predicts the direction of allele frequency changes, (ii) reveals the reasons for these changes, (iii) is as general as natural selection, and (iv) provides a universal design principle for evolution. In this paper we evaluate these claims, and show that all of them are unfounded. If the objective is to analyze whether mutations that modify social behavior are favored or opposed by natural selection, then no aspect of inclusive fitness theory is needed.

    There have been no reports evaluating progression-free survival (PFS) as a surrogate endpoint in resectable esophageal cancer. This study was conducted to evaluate the trial level correlations between PFS and overall survival (OS) in resectable esophageal cancer with preoperative therapy and to explore the potential benefit of PFS as a surrogate endpoint for OS. A systematic literature search of randomized trials with preoperative chemotherapy or preoperative chemoradiotherapy for esophageal cancer reported from January 1990 to September 2014 was conducted using PubMed and the Cochrane Library. Weighted linear regression using sample size of each trial as a weight was used to estimate coefficient of determination (R 2 ) within PFS and OS. The primary analysis included trials in which the HR for both PFS and OS was reported. The sensitivity analysis included trials in which either HR or median survival time of PFS and OS was reported. In the sensitivity analysis, HR was estimated from the median survival time of PFS and OS, assuming exponential distribution. Of 614 articles, 10 trials were selected for the primary analysis and 15 for the sensitivity analysis. The primary analysis did not show a correlation between treatment effects on PFS and OS (R 2 0.283, 95% CI [0.00-0.90]). The sensitivity analysis did not show an association between PFS and OS (R 2 0.084, 95% CI [0.00-0.70]). Although the number of randomized controlled trials evaluating preoperative therapy for esophageal cancer is limited at the moment, PFS is not suitable for primary endpoint as a surrogate endpoint for OS.

    1986-01-01

    The limitation of various typical flux-limited diffusion theory and advantages of asymptotic diffusion theory with time absorption constant are analyzed and compared. The conclusions are as following: Though the flux-limited problem in neutron diffusion theory are theoretically solved by derived flux-limited diffusion equation, it's going too far to limit flux due to the inappropriate assumption in deriving flux-limited diffusion equation. The asymptotic diffusion theory with time absorption constant has eliminated the above-mentioned limitation, and it is more accurate than flux-limited diffusion theory in describing neutron transport problem
