    Nuclear equipment meters are mainly used in the industry in quality control and process control. The principle of operation consists in a shielded radioactive source together with a radiation detector such that the radiation interacts with the material to be analyzed before reaching the detector, providing real time data. Can be as their fixed and mobile mobility, the unique properties of ionizing radiation are used in three basic modes, transmission, backscatter or dispersion or induced (reactive). With the advancement and technological modernization in the world, the demand for nuclear gauges becomes increasingly larger. Currently in Brazil there are about 465 process control plants and 21 portable systems and Mozambique about 45 facilities using nuclear gauges. This font registration is done through a process called source inventory that allows also to know the category of the source, the danger or risk to human health that the source offers. The handling of this equipment requires personnel, certified, skilled and well trained in radiation protection area in accordance with the requirements of the various CNEN Rules. Due to the presence of radioactive source and because these devices are used by workers risk because there external radiation. In this context, we made the smear test in two fixed meters from the IRD industry laboratory, which determines the integrity of the source package, mandatory item in periodic integrity testing of the radiation source of this type of device. A set of procedures is made for its implementation as an evaluation of the radiological risk by radiological survey. It was intended to contribute to the learning handling and safe use of these meters. (author)

    The industries of mining, pulp, oil, etc. which require a quality control in the processes, use the nuclear meters with sealed radioactive sources coupled to a radiation detector that generate accurate and fast answers regarding the level, thickness, density and humidity of different types of materials. Nuclear meters are classified as fixed or portable and use transmission, backscatter or reactive systems. As they use radioactive sources with various ranges of activities, they are classified by the International Atomic Energy Agency - AIEA as Category 3 and 4, of medium and low radiological risk, and must therefore have a suitable level of radiation protection for safe use in the installation. The Brazilian National Energy Commission - CNEN controls approximately 500 authorized facilities with nuclear meters. The paper technically describes the nuclear meters and the radiological protection procedures that must be followed for the safety of the IOEs (occupationally exposed individuals) and individuals from the public, based on the specific nuclear meter test program for CNEN radiation protection supervisor. The professionals who handle these nuclear meters should be aware of the radiological risk to their own protection and to individuals in the public. For safe operation with nuclear meters, a number of requirements must be observed according to the type and need of the installation.

    Full Text Available In agricultural pumping plants flowmeters are frequently installed with insufficient straight sections of pipe both upstream and downstream from the meter, in order to meet the established installation specifications. It has been found that flowmeter manufacturers do not know the error rate in flow measurements under these no optimal conditions. In 1998, Hanson found that a propeller flowmeter had an error of 3,5 % when it was installed in a position a distance of two pipe diameters downstream from an elbow. This project investigated the performance of a turbine flowmeter under no optimal upstream and downstream conditions (conditions not considered by Hanson. Experiments were carried out in the Hydraulic Laboratory of the University of Guanajuato. Measurements were made in different flowmeter positions considering different flow rates. Results from this project showed that the flowmeter does not have a large error, even if it is installed in an incorrect position. However, lowest error rate is obtained when it was installed in the position recommended by the manufacturer. En pozos agrícolas, frecuentemente se presenta el caso de trenes de descarga con insuficientes tramos rectos para cumplir las especificaciones de instalación de medidores de flujo. Los fabricantes no conocen la variación del error de medición en que se incurre si los medidores se colocan bajo condiciones de insuficientes tramos rectos. Hanson (1998 encontró que un medidor de propela presenta un error de 3,5 % si se coloca con dos diámetros aguas abajo de un codo de 90o. Para conocer el desempeño de un medidor de turbina con poco tramo recto, tanto aguas arriba como aguas abajo (condiciones no consideradas por Hanson se realizaron pruebas en el Laboratorio de Hidráulica de la Universidad de Guanajuato. Se compararon las lecturas del medidor contra las de un tanque volumétrico, colocando el medidor en diferentes posiciones y con varios gastos. Los resultados indican que

Finally, is a plan to be able to realize a recovery of thermal power of the reactor, showing as carrying out their estimations. As a result of the application of ultrasonic technology in the feedwater of reactor BWR-5 in Laguna Verde, in the Unit 1 cycle 13 it was recover an equivalent energy to a thermal power of 25 MWt in the reactor and an exit electrical power of 6 M We in the turbogenerator. Also in the Unit 2 cycle 10 it was recover an equivalent energy to a thermal power of 40 MWt in the reactor and an exit electrical power of 16 M We in the turbogenerator. (Author)

  12. NECESSIDADE E LIBERDADE EM HANNAH ARENDT

    Odílio Alves Aguiar

    2015-07-01

    Full Text Available O presente artigo visa refletir sobre o pensamento de Hannah Arendt à luz do par conceitual necessidade-liberdade. Esse caminho é produtivo, pois dá conta tanto da obra mais conhecida e reconhecida da autora quanto das suas reflexões anteriores à Origens do Totalitarismo, que se dirigiam, na sua maioria, à comunidade dos Judeus e tinham a questão judaica como ponto central. As meditações arendtianas sobre o judaísmo, consideradas no presente artigo, foram publicadas em duas coletâneas na França: La tradition Cachée (1987 e Auschwitz et Jérusalem (1991. O artigo gravita em torno da defesa arendtiana sobre a inerência entre política e liberdade e sua substituição pela compreensão da política como submetida à esfera da necessidade. Essa perspectiva, segundo a autora, fez-se presente na tradição assimilacionista entre os judeus, mas já tinha obtido a hegemonia na cultura ocidental. Isso sucedeu em razão da primazia da vita contemplativa sobre a vita activa, do trabalho e da questão social em detrimento da ação e, por fim, da supremacia da filosofia da história em prejuízo da Filosofia Política.

    Full Text Available This research introduces the development of an electronic flowmeter based on the drag force that a body experiences when immersed in a fluid stream. Its main goal was the development of an Electronic Drag Force Flowmeter (EDFF using a load cell, as well as the evaluation of its performance parameters. The developed flowmeter should not require specialized labor, equipments, computers or any sophisticated and complex method, providing an easy and accurate way of flow estimation. This research was carried out in the following stages: (i EDFF mechanical structure development; (ii data acquisition system and embedded software design; and (iii evaluation of EDFF performance parameters. EDFF has routines for instantaneous flow rate measurement, interactive calibration, and also several flow meter parameter adjustments, allowing data transmission via a RS232 protocol. The real-time flow measurement task updates values of instantaneous flow rate each seven seconds, enabling unit selection. The interactive calibration routine guides users during all calibration process showing instructions on EDFF's display. A data digital filtering procedure was implemented in an embedded software using the Grubbs' Test in order to identify and to remove outliers from the acquired data. The Method of Least Squares was also implemented in the embedded software in order to calculate the fitting model coefficients on the calibration procedure. This flowmeter is able to work from 1.94 to 7.78 dm³ s-1 with an uncertainty of ± 5.7%. The coefficient of local head loss (K was close to 0.55 for Reynolds number values higher than 10(5. The developed EDFF is a low-cost and stand-alone system with potential for agricultural applications.Este estudo apresenta o desenvolvimento de um medidor de vazão baseado na força de arraste que atua em um corpo imerso em uma corrente líquida.

    Full Text Available OBJETIVO: As unidades de terapia intensiva recorrem às equações preditivas, para determinar o gasto energético, ou às recomendações estabelecidas por sociedades internacionais, devido à inacessibilidade da calorimetria indireta. O objetivo deste trabalho foi comparar o gasto energético de pacientes críticos, por calorimetria indireta, aos calculados por meio da equação de Harris-Benedict. MÉTODOS: Estudo retrospectivo observacional realizado no Serviço de Cuidados Intensivos 1 do Centro Hospitalar do Porto. Foram avaliadas as necessidades energéticas, desde janeiro de 2003 até abril de 2012, dos pacientes críticos internados em que foi realizada calorimetria indireta. Procedeu-se ao cálculo da precisão (intervalo de ±10% entre os valores medidos e estimados, da diferença média e dos limites de concordância da equação estudada. RESULTADOS: Foram avaliados 85 pacientes, em que se efetuaram 288 medições por calorimetria indireta. Valores obtidos para necessidades energéticas em diferentes métodos: calorimetria indireta 1.753,98±391,13 kcal ao dia (24,48±5,95 kcal/kg ao dia, equação de Harris-Benedict 1.504,11±266,99 kcal ao dia (20,72±2,43 kcal/kg ao dia. A precisão da equação foi de 31,76%, a diferença média de -259,86 kcal ao dia, com limites de concordância entre -858,84 a 339,12 kcal ao dia. O gênero (p=0,023, a temperatura (p=0,009 e o índice de massa corporal (p<0,001 revelaram-se fatores com impacto significativo no gasto energético. CONCLUSÃO: A equação de Harris-Benedict não é precisa na determinação do gasto energético, subestimando-o e apresentando diferenças significativas para predizer, a nível individual, o gasto energético real.

    This research work presents the design and construction of a single-phase microcontroller-based digital electric energy meter. The digital instrument displays the energy demand (kw-h) based on up-to-date tariff provided by the Mexican national utility Comision Federal de Electricidad (CFE). The meter digitally processes voltage and current line waveform samples taken at its input, displaying, in real time, the number of electrical parameters calculated. For a better instrument performance a PIC16F874 microcontroller from microchip has been used as computational core. The parameters of interest are visualized in a liquid crystal display of 2 X 16 characters. The user interface includes a menu where some of the parameters can be selected by the operator. In the event of an electric power supply disruption the meter keeps to the energy consumption in memory. The voltage and current measured levels ranges from 1 to 255 Vrms and 0.1 to 25.5 Arms, respectively. The power is displayed in 5 digits ranging from 0 to 6502.5 watts and the energy is displayed with 5 whole digits and 5 decimals ranging, from 0 kWh up to 99999.99999 kWh. These values are refreshed every one second together with the actual electrical consumption cost which ranges from 0 up to 9999.9 pesos. The digital measuring instrument has been built based on four main inter-connected modules named, data acquisition; signal conditioning; signal processing; and display. A set of efficient assembly code routines has been developed in order to calculate the number of electrical parameter previously described. After a debugging process, the optimised code has been assembled for the PIC16F874.

Localizamos a questão no amplo debate sobre a contemporaneidade e a globalização e elegemos a centralidade das categorias espacialidade, temporalidade e cotidianidade nesta tentativa de compreender um pouco mais o consumo de produtos noticiosos, inserido nas práticas discursivas e narrativas jornalísticas atuais.

    Full Text Available Estudo qualitativo com abordagem da fenomenologia social que objetivou a compreensão da vivência da mulher idosa, suas necessidades de cuidado e expectativas nesse período da vida. Participaram nove mulheres, cujos depoimentos foram obtidos de fevereiro a maio de 2011, por meio de entrevista semiestruturada. A mulher idosa refere limitações de ordem física, mental e social, e valoriza a preservação de sua autonomia nas atividades diárias e no cuidado consigo mesma. Refere a família como suporte fundamental e tem expectativas e necessidades de se manter saudável, da busca pelo lazer e de ter melhor acesso aos serviços de saúde para receber informações e atendimento qualificado. Nessa fase, a ausência de perspectivas relaciona-se à perda de pessoas significativas e da saúde. Este estudo revelou facetas da vivência da mulher idosa, suscitando novas investigações e a adequação do ensino, prática e gestão às reais necessidades dessa mulher.

    O atual sistema de produção e consumo utiliza a comunicação publicitária para transmitir aos receptores-consumidores a necessidade de uma economia de crescimento exponencial. A publicidade comercial convencional produz realidades que devem ser objeto de desejo e, em última instância, necessidade. Contudo, tais necessidades não dão lugar a uma vida boa de ser vivida. Ao contrário, as narrativas publicitárias mercantilizadas provocam distâncias sociais, agravam os efeitos prejudiciais da econom...

    2011-12-01

    Full Text Available Objetiva-se apresentar categoria referente a necessidades relacionadas à autonomia, reconhecidas pelos profissionais da Estratégia Saúde da Família no que concerne à atenção à saúde de mulheres que vivenciam violência. Para a produção do material empírico foram feitas entrevistas com profissionais de saúde que compõem as equipes da ESF e com mulheres usuárias do serviço. Os significados conformam a necessidade de autonomia relacionada à mulher como sujeito na tomada de decisões. Entretanto, alguns significados revelaram o reducionismo que se traduz na desresponsabilização do serviço em relação ao problema. A autonomia financeira foi um aspecto convergente entre os discursos dos profissionais e das usuárias do serviço de saúde. Concluiu-se que para o enfrentamento da violência é fundamental a inclusão da perspectiva de gênero tanto nas políticas de saúde quanto nas práticas concretizadas no processo de trabalho, condição que abre possibilidades de respostas a necessidades práticas e estratégicas de gênero, contribuindo para a redução da iniqüidade entre homens e mulheres e a promoção da emancipação feminina.

    2003-04-01

    Full Text Available Quando se deseja iniciar uma atividade ou mesmo expandi-la, muito se analisa a necessidade de aplicações em ativos permanentes, mas pouca atenção é dedicada ao "investimento em clientes e estoques". Dessa forma a concessão de prazo para clientes ou a opção por um aumento nos níveis dos estoques, ambos valores contabilizados no ativo circulante, pode significar uma decisão de investimento tão ou mais duradoura do que aquela efetuada em ativos permanentes. A Necessidade de Capital de Giro (NCG, e suas variações, podem levar à falência muitas empresas, principalmente pequenas e médias. Além da preocupação monetária, uma empresa necessita garantir a manutenção de sua estrutura física, permanente e operacional, necessária para suas atividades. O lucro contabilizado através do Custo Corrente Corrigido (CCC, precisa de ajustes para ser considerado totalmente distribuível; sob nosso ponto de vista, as variações da NCG fazem parte desses ajustes. A idéia central deste artigo é a criação de uma Reserva de Capital denominada Reserva das Variações da Necessidade de Capital de Giro (RVNCG como forma de garantir a manutenção do capital físico da empresa, ajustando o lucro passível de distribuição através da contabilização das variações da NCG. Esse artigo está dividido em quatro partes. Na primeira, percorremos o embasamento teórico. No desenvolvimento, segunda parte, traçamos os objetivos, as premissas e descrevemos a criação e a contabilização da RVNCG. Na terceira parte, demonstramos a proposta do artigo através de três exemplos numéricos com os respectivos Balanços Patrimoniais e Demonstrações do Resultado, mostrando a utilização proposta da RVNCG; por fim, na quarta e última parte apresentamos nossas conclusões.When we want to begin or expand an activity, the need to invest in permanent assets is profoundly analyzed, but little attention is given to the investment in clients and inventories

    Full Text Available O artigo discute as práticas inclusivas nos serviços de atenção psicossocial, de forma a articular a concessão de benefícios sociais à dimensão da práxis clínica, pautada na escuta do sujeito. Retoma-se o contexto de criação do campo da saúde mental no Brasil, ressaltando a importância do modelo basagliano para a consolidação dos movimentos sociais que protagonizaram a luta contra o modelo asilar de tratamento da loucura e pela inclusão social dos pacientes psiquiátricos. Em seguida, discorremos acerca da escuta clínica na teoria psicanalítica, no intuito de asseverar o desenvolvimento desta como elemento fundamental para o trabalho institucional. Utilizam-se os conceitos psicanalíticos de necessidade, demanda e desejo, com o propósito de articulá-los à noção de escuta nos serviços substitutivos. Por fim, indicamos que a relação entre a psicanálise e a saúde mental implica a aposta que se faz no desejo, na emergência do sujeito como resultado de um trabalho clínico dentro das instituições, na medida em que essa aposta nos permite escapar de certa normalização dos usuários de saúde mental a um convívio social aceitável.

    Full Text Available Estabelecer as necessidades energéticas de pacientes com doença renal crônica é importante para que se possam tratar os distúrbios nutricionais encontrados nessa população. Segundo os guias de condutas voltados ao cuidado nutricional de pacientes com essa doença, a recomendação energética pode variar entre 30 e 40kcal/kg/dia. Contudo, trabalhos que avaliaram os componentes do gasto energético nos pacientes com doença renal crônica sugerem que as necessidades energéticas dessa população podem diferir do valor recomendado acima, a depender da condição clínica (presença de comorbidades, da modalidade de tratamento empregado e do nível de atividade física. Dessa forma, o presente trabalho tem como objetivo fazer uma revisão dos estudos sobre o gasto energético de pacientes com doença renal crônica, com o intuito de abordar as seguintes questões: (1 as atuais recomendações de energia para pacientes com doença renal crônica estão adequadas? (2 qual equação de predição poderia ser empregada para estimar as necessidades energéticas desse grupo de pacientes? Assim, esta revisão busca auxiliar o nutricionista ao estimar as necessidades energéticas de pacientes com doença renal crônica.

    2012-12-01

    Full Text Available Análises de necessidades de treinamento (ANTs, apesar de importantes, têm sido realizadas de modo pouco sistemático em ambientes organizacionais. A análise da literatura mostra que a produção intelectual nessa área está restrita a análises nos níveis do indivíduo e das tarefas, com poucas pesquisas enfocando necessidades em níveis mais abrangentes como grupos, equipes ou macroprocessos organizacionais. De modo geral, as abordagens de análise de necessidades ainda estão focadas em cargos ou nas estruturas organizacionais rígidas, estáticas, burocráticas (departamentos, divisões etc.. Essa característica torna a ANT anacrônica e pouco útil, pois não capta novos arranjos organizacionais como arquiteturas matriciais, organização em rede, organizações virtuais ou novas configurações dos trabalhos humanos. Esse caráter dinâmico implica uma mudança no caráter da ANT, para uma abordagem mais prospectiva, voltada à aprendizagem de habilidades complexas e de alta volatilidade. Este ensaio teórico objetiva rever a literatura da área e propor um modelo de diagnóstico de necessidades de treinamento baseado em taxonomia de resultados de aprendizagem e com foco em diversos níveis de análise. O modelo de ANT proposto deriva de um conjunto de resultados de pesquisas empíricas e vai além da análise de tarefas e de pessoas, incluindo também o nível organizacional e de grupo. A aplicação deste modelo permite fornecer as informações necessárias ao desenho de situações de aprendizagem e de treinamento que possam promover o desenvolvimento de complexas competências valorizadas pelo mundo do trabalho, cujo desenvolvimento requer ações educacionais variadas, currículos e programas de aprendizagem contínua e de educação permanente (ao longo de toda a vida.

    Full Text Available A herdabilidade da necessidade de calor para antese e brotação em pessegueiro [Prunus persica (L. Batsch] foi estudada em ramos de 16 cultivares e seleções de baixa, média e alta necessidade de calor e 11 progênies oriundas de hibridações entre elas. Os ramos foram submetidos, previamente, a 2 ºC por 500 horas para satisfazer a necessidade de frio. O valor estimado da herdabilidade média para a necessidade de calor em gemas florais foi de 45% e 57%, em 1999 e 2000, respectivamente. Para gemas vegetativas, o valor estimado foi de 30%, em 1999. 'BR-1', 'Barbosa', 'Chula', 'Chinoca' e 'Eldorado' transmitem melhor o caráter necessidade de calor para as progênies do que os demais genótipos estudados. Os registros observados suportam um modelo de herança quantitativa com genes de maior efeito para menor necessidade de calor. A seleção de indivíduos com maior necessidade de calor para floração tende a retardar a floração sem, contudo, retardar com a mesma intensidade a época de brotação.Heritability of heat requirement for blooming and leafing was investigated in peach [Prunus persica (L. Batsch], using artificially chilled excised shoots of 11 populations and 16 parental clones of low, intermediate and high heat requirement. The estimated values of broad sense heritability of heat requirement in flower buds were 45% and 57%, in 1999 and 2000, respectively. In leaf buds, the heritability was 30% in 1999. 'BR-1', 'Barbosa', 'Chula', 'Chinoca', and 'Eldorado' can transmit the heat requirement character better to offspring than the others studied genotypes. The data support a model for quantitative inheritance with partial dominance for low heat requirement. Seedling selection for high heat requirement delay blooming more than leafing.

    Full Text Available Introdução: A mulher em processo de parto está exposta a ocorrência de traumas perineais que podem estar associados à assistência. Objetivo: Verificar a associação entre a presença de perineorrafia e problemas perineais, atividades habituais e necessidades fisiológicas afetadas em  puérperas no pós-parto vaginal. Materiais e Métodos: Estudo transversal, composto por 870 puérperas com algum tipo de trauma perineal durante o parto vaginal. Os dados foram coletados através da entrevista estruturada e exame físico da região vulvoperineal e submetidos a análise descritiva e inferencial. Resultados: Houve associação estatisticamente significativa entre a episiorrafia e a ocorrência de edema (p<0,001, ardor (p=0,002 e dor (p=0,002. Concernente às atividades habituais e necessidades fisiológicas, mulheres com episiorrafia apresentaram maior dificuldade para vestir-se, deambular, sentar e dormir. Em contrapartida, apresentaram menor dificuldade para urinar e realizar higiene íntima. Discussão: Dentre os problemas perineais, observou-se diferença estatisticamente significativa quanto a ocorrência de edema, ardor e dor entre os grupos, sendo que as mulheres com episiorrafia relataram menos ardor perineal em comparação ao grupo com perineorrafia devido a laceração espontânea. Nesse sentido, preservar a integridade perineal das parturientes é algo necessário e possível na assistência obstétrica, visto que esse tipo de intervenção, por vezes desnecessária, desencadeará desconfortos que irão interferir no seu bem-estar durante o período puerperal. Conclusões: Os dados deste estudo permitiram verificar que há associação entre a perineorrafia e a ocorrência de problemas perineais e alterações para realização de atividades habituais no puerpério imediato.

    Full Text Available O cooperativismo possui grande relevância para a economia brasileira, na medida em que atua apoiando o desenvolvimento econômico e social, principalmente das pequenas propriedades rurais. As cooperativas agropecuárias atuam no fomento e na comercialização dos produtos agrícolas, inclusive implantando novos cultivos e agregando valor aos produtos por meio de complexos agroindustriais. O crescimento dessas organizações, sobretudo pela verticalização de suas operações, tem exigido a busca de fontes de capital para financiar as necessidades líquidas de capital de giro dos seus negócios. Decisões sobre financiamento afetam diretamente a saúde financeira das organizações, à medida que produzem um risco financeiro maior. Portanto é relevante uma investigação sobre as fontes de financiamento das necessidades líquidas de capital de giro para as cooperativas agropecuárias, sendo este o objetivo primordial do artigo.The cooperativism has great relevance to Brazilian economics, as it supports the social and economical development, mainly in the small agricultural properties. The farming cooperatives work on the processing and commercialization of agricultural products, including implanting new kinds of crops and aggregating value to the products through agroindustrial complexes. The growth of these organizations, mainly through verticalization of its operations, has required the quest for capital founts to finance the needs for fluent capital in their business. Decisions concerning financing affect directly the financial health of the organizations, as they produce a bigger financial danger. Therefore it is relevant an investigation on the financing founts for the needs of fluid capital to the agricultural cooperatives, and this is the main goal of this article.

    Full Text Available A Escola Inclusiva pressupõe um atendimento a uma população cada vez mais diversa e heterogênea, onde todos devem obter uma resposta qualificada para as suas necessidades educativas, através das adaptações curriculares ao Currículo formal. Deste modo, as escolas devem incluir nos seus projetos educativos as adaptações curriculares relativas ao processo de ensino e aprendizagem, necessárias para responder adequadamente às crianças e jovens com Necessidades Educativas Especiais (NEE, com vista a optimizar a sua participação nas actividades. Atualmente tornou-se um desafio determinar com exactidão quais os alunos com NEE e, consequentemente, quais os alunos a serem intervencionados pela Educação Especial, nomeadamente alunos com NEE de caráter permanente. Neste contexto, surge a Classificação Internacional de Funcionabilidade, Incapacidade e Saúde (CIF, preconizada pela OMS (2001 e actualizada em 2003, que constitui uma ferramenta pedagógica no processo de elegibilidade, avaliação e intervenção de alunos com NEE. Observa-se uma mudança de paradigma, onde se pretende não só classificar os níveis de funcionalidade do indivíduo, como também os factores ambientais que podem funcionar como barreiras ou facilitadores dessa mesma funcionalidade. Nesta perspectiva a formação de professores, é assim considerada como um factor importante para o sucesso. Deste modo a formação contínua deve preconizar e permitir uma mudança de práticas dos professores e educadores, isto é, uma mudança de prática na educação, na intervenção educativa.

Metodologia: A população-alvo deste estudo foi composta por 74 alunos, de ambos os sexos, regularmente matriculados, que preencheram os critérios de inclusão previamente estabelecidos e por seus responsáveis. O estudo foi conduzido em duas etapas: a primeira consistiu na aplicação de um formulário aos responsáveis pelos PNE, e a segunda, na realização de um exame clínico intrabucal, realizado por um examinador e anotador previamente calibrados, em que se avaliaram as condições de saúde bucal dos alunos por meio do Índice de Cárie Dentária (CPO-D, do Índice de Higiene Oral Simplificado (IHOS e da presença de Trauma Dentário. Resultado: Observou-se que 75,4% dos alunos já haviam recebido algum tipo de tratamento odontológico; destes, 50,9% afirmaram ter sido na Unidade Básica de Saúde. O CPO-D médio foi de 12,6 (±8,4, 52% apresentaram higiene oral deficiente e o trauma dental foi observado em 19,3% dos alunos analisados. Com relação ao parto, 51% das mães relataram ter tido uma gestação normal e 54,4% nunca haviam sido orientadas com relação aos cuidados com a saúde bucal do filho. Entre as dificuldades relatadas pelos responsáveis para manter a saúde bucal do PNE, 33,3% afirmaram ser encontrar um Dentista que o atenda e 33,3% apontaram o custo do tratamento. Conclusão: Os altos índices revelados pelo CPO-D, bem como a higiene oral deficiente, somados às dificuldades relatadas em se realizar o acompanhamento odontológico desses indivíduos, mostram a necessidade da implementação de políticas públicas mais voltadas à atenção a esses pacientes.

    Full Text Available Pesquisa qualitativa que objetivou descrever a rede social de cuidados de uma criança com necessidade especial de saúde. Os participantes da pesquisa foram os avós de uma criança, sorteados a partir do banco de dados de uma pesquisa. O Método Criativo Sensível foi desenvolvido por meio da Dinâmica de Criatividade e Sensibilidade Mapa Falante posteriormente submetida à Análise de Discurso em sua corrente francesa. Os resultados apontaram que os familiares da criança possuem uma rede social fragmentada e solitária constituída por serviços de saúde de nível secundário e terciário; que a criança dependente de tecnologia é marginalizada no Sistema Único de Saúde, sendo invisíveis na rede primária. Conclui-se que os familiares da criança apoiam-se nos serviços que prestam cuidados a criança, que a rede familial está restrita aos familiares mais próximos. Sugere-se que a enfermagem possibilite a formação de redes e o acesso à assistência em saúde dessas crianças.

A experiência das pessoas é autêntica e representativa do todo com a construção de uma identidade comum. É a identidade que dá qualidade à memória de um grupo. Assim, cada memória é um fenômeno social. Analisou-se a experiência de 12 mulheres que quase morreram em função do estado gravídico-puerperal. O método da história oral temática foi utilizado, na perspectiva das necessidades de saúde e direitos humanos. Seis memórias coletivas compuseram os discursos: necessidades de saúde não atendidas; deficiências assistenciais; privação do contato com o filho; violação de direitos; ausência de reivindicação dos direitos; e compensações dos direitos e necessidades não atendidos. Compreender as necessidades de saúde dessas mulheres é reconhecê-las como sujeitos de direitos; é individualizar a assistência, respeitando sua autonomia, garantindo o acesso às tecnologias e estabelecendo vínculo (aefetivo com o profissional de saúde

    Full Text Available O objeto deste artigo é o conceito de verdade tal como se articula no oráculo de Ifá cubano; seu objetivo é ilustrar a fecundidade de um "método ontográfico" que procure mapear as premissas ontológicas do discurso nativo por meio da produção de conceitos que, não sendo os conceitos nativos eles mesmos, constituam equivalentes aproximados destes. Enfatizando a afirmação dos praticantes de que o Ifá é infalível, propõe-se que os vereditos divinatórios devem ser entendidos como verdades necessárias, isto é, como enunciados que não poderiam não ser verdadeiros. Em seguida, mostrando que, do ponto de vista das concepções comuns de verdade, a necessidade modal dos oráculos só pode parecer um absurdo dogmático, procura-se avançar uma conceitualização alternativa que concorde com as convicções dos informantes, examinando um complexo de conceitos e práticas associados ao oráculo a fim de avaliar as premissas que garantem a verdade e sua emergência na prática do Ifá.This article analyzes the concept of truth as employed by Ifá oracles in Cuba; its aim is to illustrate the fertility of an 'ontographic method' dedicated to mapping the ontological premises of native discourse through the production of concepts which, while not the native concepts themselves, comprise close equivalents to them. Emphasizing practitioners claims that the Ifá is infallible, it is proposed that divinatory verdicts should be understood as necessary truths, that is, as statements which cannot not be true. Then, after showing that from the viewpoint of common place conceptions of truth, the modal necessity of oracles can only appear a dogmatic absurdity, I propose an alternative conceptualization which agrees with the convictions of informants. This involves examining a complex of concepts and practices linked to the oracle in order to evaluate the premises which ensure truth and its emergence in Ifá practice.

Nesse trabalho objetivou-se observar se as instituições da rede estadual de ensino da cidade de Passo Fundo estão adaptadas para atenderem as necessidades dos portadores de deficiência física. Após identificadas as escolas em potenciais para essa pesquisa (determinou-se escolas com mais de 500 alunos, foram realizadas visitas com a finalidade de realizar uma entrevista com os diretores das escolas e observar os ambientes da escola. Sendo assim, foram visitadas 22 escolas localizadas na zona urbana da cidade de Passo Fundo/RS. Verificou-se que 50% das escolas tem prédio térreo, o que permite uma melhor circulação por parte dos alunos portadores de necessidades especiais, e 50% das escolas tem prédios com 2 ou 3 pisos, fazendo com que as escadas seja um grande fator de limitação aos alunos com necessidades especiais. Desta, 41% apresentam 2 pisos e 9% três pisos. Nas escolas pesquisadas não foram encontradas rampas nos acessos principais em 50% das escolas, ou seja, em 11 escolas e o mesmo número de escolas apresentou diferenças de nível nos acessos principais, dificultando assim o acesso dos portadores de necessidade especiais. Verificou-se que das 22 escolas pesquisadas 15 escolas têm alunos portadores de necessidades especiais matriculados, ou seja, 68% das escolas.

    Full Text Available A motivação é um tema complexo, abordado por diversos pesquisadores que elaboraram teorias visando explicar o fenômeno motivacional e sua influência sobre o comportamento humano. Entre as teorias de motivação, uma importante teoria é a Hierarquia de Necessidades de Maslow que relaciona a motivação das pessoas a um conjunto de necessidades. Sendo assim, o presente estudo teve por objetivo analisar o grau de satisfação e a questão motivacional de pessoas para as necessidades fisiológicas, de segurança, sociais, de estima e autorrealização. O estudo foi realizado em uma empresa do setor mecânico, localizada na região Centro Ocidental do Paraná. Para a realização do estudo, foi aplicado um questionário a 40 pessoas, de diferentes características, como idade, gênero, escolaridade e renda familiar. Com base nos resultados, constatou-se que, de maneira geral, os entrevistados estão satisfeitos pelo atendimento às necessidades fisiológicas, como alimentação, moradia, vestuário e descanso, porém, outras necessidades, dispostas em outros níveis da pirâmide de Maslow, não foram completamente atendidas e, portanto, resultam em insatisfação pela ausência de estímulos motivacionais.   Motivation is a complex subject, addressed by different researchers who elaborate theories aiming explain the motivational phenomenon and its influence on human behavior. Among the theories of motivation, an important theory is Maslow's Hierarchy of Needs that relates people's motivation needs set. In this way, the present study aimed to analyze the degree of satisfaction and motivational question of people for the physiological, safety, social, esteem and self-fulfillment needs.

Identificou-se que os usuários perceberam-se como detentores de necessidades; o contexto social pode apresentar forte influência na sua saúde, verificando-se que a autonomia na tomada de decisões é uma necessidade. Quanto ao vínculo, percebe-se que está intimamente ligado às necessidades de autonomia/autocuidado, pois de certo modo é reforçando a relação de confiança que será possível fortalecer os potenciais para o enfrentamento do processo saúde-doença. Conclui-se que existe a necessidade de instrumentos que auxiliem o profissional da área da Saúde Coletiva a identificar as necessidades de saúde dos usuários.

    Full Text Available RESUMO Objetivo: Verificar a presença de associação entre a avaliação objetiva e subjetiva da necessidade de tratamento ortodôntico em adolescentes e seu impacto na autoestima. Métodos: Estudo transversal com adolescentes de 10 a 17 anos da cidade de Sri Ganganagar, Rajastão, Índia. Foi utilizado o Índice de Ortodontia de Saúde Dental (IOTN para avaliar de modo objetivo a necessidade de tratamento (DHC e o componente estético desse índice (AC para a avaliação subjetiva. Os estudantes selecionados foram também avaliados quanto a traumatismos dentários, perda dentária e cárie dentária. Aplicou-se a escala de autoestima de Rosenberg para determinar o nível de autoestima dos estudantes. Os dados foram analisados por regressão linear múltipla, testando a associação individual das diferentes variáveis clínicas independentemente da autoestima dos adolescentes, de acordo com o escore da escala de Rosenberg. Resultados: Entre 1.140 adolescentes estudados, a prevalência da necessidade de tratamento ortodôntico avaliado de modo objetivo pelo IOTN-DHC ocorreu em 56,9% dos indivíduos. A avaliação subjetiva do adolescente (IOTN-AC revelou prevalência de necessidade de tratamento de 53,3%. A análise multivariada mostrou que, além de todos os problemas dentários, o componente objetivo (IOTN-DHC, seguido do componente estético subjetivo (IOTN-AC, teve maior impacto na autoestima dos estudantes analisados. Conclusões: A insatisfação com a aparência dental é um forte preditor de baixa autoestima na adolescência.

    Full Text Available Estabelecer as necessidades energéticas de pacientes com doença renal crônica é importante para que se possam tratar os distúrbios nutricionais encontrados nessa população. Segundo os guias de condutas voltados ao cuidado nutricional de pacientes com essa doença, a recomendação energética pode variar entre 30 e 40kcal/kg/dia. Contudo, trabalhos que avaliaram os componentes do gasto energético nos pacientes com doença renal crônica sugerem que as necessidades energéticas dessa população podem diferir do valor recomendado acima, a depender da condição clínica (presença de comorbidades, da modalidade de tratamento empregado e do nível de atividade física. Dessa forma, o presente trabalho tem como objetivo fazer uma revisão dos estudos sobre o gasto energético de pacientes com doença renal crônica, com o intuito de abordar as seguintes questões: (1 as atuais recomendações de energia para pacientes com doença renal crônica estão adequadas? (2 qual equação de predição poderia ser empregada para estimar as necessidades energéticas desse grupo de pacientes? Assim, esta revisão busca auxiliar o nutricionista ao estimar as necessidades energéticas de pacientes com doença renal crônica.Estimating the energy requirement of patients with chronic kidney disease is highly important for treating the nutritional disorders often seen in this population. According to the specific guidelines for patients with chronic kidney disease, the currently recommended daily energy intake varies from 30 to 40kcal/kg/day. However, studies that investigated energy expenditure components of patients with chronic kidney disease suggested that the energy requirement may differ from the one proposed earlier, depending on overall clinical condition (i.e. presence of comorbidities, treatment modality and level of physical activity. With this perspective in mind, the present study aims to review the studies assessing energy expenditure

    Full Text Available The difficulties presented by Brazilian students in the appropriation of the negative number reported in surveys contributed to this article preparation. Concerned about these difficulties, we turned to Davydov’s proposition, which is the subject of this study. The research problem is: what are the needs created in the particular tasks of Davydov’s educational organization for the introduction of the negative numbers concept, in school situation? It is a qualitative research method in the literature whose source analysis are four tasks presented in the student textbook belonging to Davydov’s proposition. The review process was developed through necessity category: conceptual and pedagogical. The research shows that the need to study the negative numbers is based on the fact that only they enable the resolution of some cases of subtraction and equation. To provide the meaning of opposite to the negative number, the main need is the change from scalar quantities to the vector one. As dificuldades apresentadas por estudantes brasileiros na apropriação do número negativo relatadas em pesquisas contribuíram para a elaboração desse artigo. Preocupados com tais dificuldades, recorremos à proposição davydoviana que é objeto desse estudo. O problema de pesquisa é: quais são as necessidades criadas nas tarefas particulares da organização de ensino davydoviano para a introdução do conceito de número negativo, em situação escolar? Trata-se de uma pesquisa qualitativa na modalidade bibliográfica cuja fonte de análise são quatro tarefas presentes no livro didático do estudante pertencente à proposição davydoviana. O processo de análise se desenvolveu por meio da categoria necessidade: de ordem conceitual e pedagógica. A pesquisa evidencia que a necessidade do estudo dos números negativos decorre de que apenas eles possibilitam a resolução de alguns casos de subtração e equação.

    Full Text Available O presente estudo teve como objetivos: desenvolver uma metodologia de avaliação de necessidades de treinamento que incluísse atitudes; estudar a relação entre auto e hetero-avaliação, buscando avaliar conhecimentos, habilidades e atitudes; e avaliar a relação entre a auto-avaliação e algumas variáveis preditoras (tempo de trabalho na organização e na função, emprego anterior, gênero, estado civil, escolaridade e idade. Foram desenvolvidos questionários, de acordo com o método de análise de papel ocupacional. Esses questionários foram aplicados em 898 bancários e seus supervisores imediatos. Os resultados sugeriram que a metodologia parece ser adequada para analisar necessidades de treinamento. Mostraram também que existe relação significativa entre auto e hetero-avaliação de necessidades de treinamento, embora supervisores tendam a apontar maiores necessidades de treinamento, em seus subordinados, do que as auto-avaliações destes mesmos.The objectives of the present study were: to develop a training needs assessment methodology that included attitudes; to study the relationship between self and hetero assessment, by assessing knowledge, skills and attitudes; and to evaluate the relationship between self-assessment and some predicting variables (work experience at the organizational and occupational levels, prior job experience, gender, marital status, schooling and age. Questionnaires were developed, following the method of occupational role analysis. These questionnaires were applied in 898 bank employees and their immediate supervisors. Results have suggested that the methodology seems to be appropriate for analyzing training needs. They have also shown that there is a significant relationship between self and hetero assessments of training needs. However, supervisors tend to point higher training needs, in their subordinates, than the self-assessments made by the latter.

  3. As necessidades e os desejos na formação discursiva do marketing: base consistente ou retórica legitimadora?

    Vinícius Andrade Brei

    Full Text Available Neste artigo realizamos uma análise crítica da gênese histórica da área de marketing até sua constituição atual, com um foco principal: verificar se as necessidades e os desejos dos clientes são base consistente da formação histórica, discursiva, do marketing ou, apenas, retórica legitimadora para a atuação da área. Adotamos uma orientação filosófico-epistemológica baseada na teoria do discurso proposta por Michel Foucault, que nos permitiu constatar que a centralidade das necessidades e dos desejos dos clientes no discurso contemporâneo do marketing é resultado de uma série de transformações e disputas históricas pela hegemonia de uma determinada idéia ou ponto de vista, mas sempre ancorada em condições socioeconômicas, ambientais, favoráveis às transformações ocorridas. Em outras palavras, concluímos que as transformações discursivas, constituintes da área, foram o resultado de um processo produzido social e historicamente, tendo ocorrido muito mais como um resultado de mudanças na economia e no mundo empresarial do que como uma espécie de "vocação" natural do marketing.

    Full Text Available Objetivo: identificar necessidades de aprendizagem de alunos da Educação Profissional Técnica (EPT em Enfermagem. Estudo qualitativo, realizado em município do Estado de São Paulo. Método: os sujeitos foram alunos, professores e coordenadores da EPT e alunos do curso de bacharelado e licenciatura do ensino superior que já tiveram contato com EPT. A coleta de dados deu-se por questionário socioeconômico e círculos de cultura sobre as necessidades de aprendizagem. Para análise de dados utilizou-se a análise de conteúdo. Resultados: constatou-se que alunos têm dificuldades em conteúdos não relacionados à Enfermagem, como português e matemática, e também em disciplinas introdutórias do curso de EPT o que possivelmente pode interferir negativamente na aprendizagem de conteúdos específicos da Enfermagem, bem como na qualidade do cuidado à saúde. Conclusão: faz-se necessário repensar os conteúdos ministrados e modos de ensinar desde a educação básica, assim como a formação do docente que hoje atua na EPT.

    Full Text Available É um desafio atender aos alunos, em suas diversas necessidades especiais. Diferentemente das deficiências, há poucas pesquisas no Brasil sobre estudantes com doenças crônicas e suas especificidades, na escola. O objetivo do presente estudo foi identificar as necessidades especiais de escolares com diabetes mellitus tipo 1. Participaram 37 familiares de escolares em tratamento ambulatorial de uma faculdade paulista, por meio de entrevista semiestruturada, gravada em áudio e transcrita para análise. Os resultados mostraram que todos comunicaram a escola a respeito da doença do filho, mas, mesmo assim, 29,7% relatam dificuldade de inclusão ou acesso à escola, como desconhecimento do professor para o controle do diabetes, merenda escolar inadequada, preconceito dos colegas e da diretora ou vergonha por parte do aluno. As faltas ocorrem com 70,3% dos alunos, principalmente devido às consultas médicas. Necessidades especiais foram identificadas por 32,4%, incluindo a alimentação, o desempenho escolar e a necessidade de profissionais da escola mais bem informados sobre a doença. Além disso, 72,9% referem algum tipo de apoio para enfrentar o diabetes, principalmente de profissionais de saúde. Dos familiares, 51,3% apresentam sugestões para um melhor desenvolvimento do filho na escola, incluindo alimentação escolar adequada e melhor preparo da escola para lidar com o diabetes, como palestras e treinamento aos professores. Sugerimos a aproximação entre a escola e a área da saúde, porém, o primeiro passo para a integração intersetorial é identificar as necessidades desses alunos com doenças crônicas, como foi possível com este trabalho, ao enfocar o diabetes mellitus e suas repercussões escolares.Catering to students according to their various special needs is a challenge. As opposed to the field of disability, there is little research in Brazil on students with chronic diseases and their specific needs at school. The

MÉTODOS: Realizou-se projeto multidisciplinar em 37 pacientes, com necessidades especiais, institucionalizados na Comunidade Rodolfo Aureliano (CRAUR, unidade da Fundação da Criança e do Adolescente (FUNDAC em Recife-PE. A faixa etária dos indivíduos institucionalizados variou de seis a 30 anos, média de 18,8 ± 5,1 anos. O sexo masculino foi mais prevalente com 35 indivíduos (94,5%. Consideraram-se como indivíduos institucionalizados, aqueles que vivem abrigados em instituições mantidas pelo Estado. Foi feito estudo de corte transversal, verificando-se os principais achados clínicos e oftalmológicos destes indivíduos. Realizou-se o exame oftalmológico completo nos casos, com boa colaboração e de acordo com protocolo pré-estabelecido. RESULTADOS: Uso de álcool na gravidez foi relatado por nove mães (24,3%. Verificou-se a presença de retardo mental grave em 22 casos (59,4 %, paralisia cerebral e epilepsia em sete (18,9% indivíduos cada. Foi possível a realização do exame oftalmológico completo em 24 indivíduos (64,8%. Detectou-se cegueira legal em dez casos (41,6%. Os diagnósticos oftalmológicos mais encontrados foram ambliopia, erro refracional e phthisis bulbi em três casos (12,5% cada. Estrabismo foi encontrado em dois casos (8,3%. CONCLUSÃO: Os achados oftalmológicos revelaram a importância do exame oftalmológico em indivíduos com necessidades especiais institucionalizados. A associação com múltiplas deficiências, tais como: doenças neuropsiquiátricas, contribuiu para o maior grau de dificuldade na avaliação e condução dos casos.

    Full Text Available O objetivo do presente estudo foi avaliar a associação entre estresse e suporte social em mães de crianças com necessidades especiais e mães de crianças com desenvolvimento típico, em famílias de baixa renda. Trata-se de estudo quantitativo com 75 mães de crianças com idade entre quatro e 8 anos, com renda familiar de até quatro salários mínimos, alocadas em dois grupos: mães de crianças com desenvolvimento típico e mães de crianças com necessidades especiais. As participantes responderam ao Inventário de Sintoma de Stress e ao Questionário de Suporte Social. Os resultados indicaram, em ambos os grupos, elevada porcentagem de mães estressadas. Mães de crianças com necessidades especiais contam com um menor número de pessoas suportivas. Observou-se associação negativa entre stress e satisfação com o suporte social. Discute-se que o presente estudo confirma achados de pesquisas anteriores e identifica o papel do suporte social nos processos de adaptação familiar. A associação encontrada entre a satisfação com o suporte social e o estresse aponta para adequação de proposições e implantação de programas de intervenções em saúde para famílias de crianças com necessidades especiais.The aim of this article is to assess the relationship between stress and social support in mothers of children with special needs, as contrasted with mothers of children with typical development, from low income families. In this quantitative study, participants included 75 mothers with children aged four to eight years, with income up to four minimum wages, divided in two groups: mothers of children with typical development and mothers of children with special needs. The mothers answered the Inventory of Stress Symptom and the Social Support Questionnaire. The results showed that mothers of both groups suffered stress. The mothers of children with special needs have a smaller number of people to support them. A negative

    Full Text Available Apesar de contribuir com a programação, a execução e a avaliação de resultados, a etapa de análise de necessidades tem sido constantemente negligenciada pela literatura científica e pela prática profissional de treinamento, cujos volumosos investimentos, portanto, tendem a ser desperdiçados. Os modelos que orientam este importante campo foram propostos há aproximadamente 50 anos, de forma que não são capazes, atualmente, de orientar teórica e metodologicamente estudiosos e praticantes da área. Nesse sentido, esta pesquisa objetivou, mediante execução de análise de covariância em amostra de 213 participantes, investigar a relação entre motivação para o trabalho e complexidade de necessidades de treinamento, com vistas a permitir a composição futura de modelos teóricos de análise de necessidades integrados, não apenas por componentes relacionados às tarefas, como prescrito na literatura, mas, também, por variáveis relativas aos níveis individual, grupal e organizacional de análise. Especificamente, quatro objetivos específicos, cada qual associado a procedimentos e técnicas de pesquisa particulares, foram determinados: (1 elaborar, por meio de pesquisa documental e grupo de foco, e validar, teórica e empiricamente, a partir de entrevista individual e realização de análises fatoriais exploratórias, instrumento para aferição das necessidades de treinamento; (2 adaptar e validar estatisticamente o instrumento de medida de motivação para trabalhar, também em função de análises fatoriais exploratórias; (3 com teste de diferença de médias entre amostras independentes, formar grupos de comparação em função do no nível de motivação para trabalhar dos respondentes; e (4 identificar variáveis de controle estatístico para composição do modelo final de investigação a partir de correlações bivariadas.

    Full Text Available Este estudo enfoca como a informática pode auxiliar portadores de necessidades especiais que possuem dificuldades de aprendizado e raciocínio, visto que a tecnologia da informação quando utilizada de forma planejada e bem estruturada permite maior absorção de conceitos e crescimento cultural, devido à gama de informações que proporciona. Este crescimento visa compreender a formação de todos os tipos de deficientes, sejam eles visuais, mentais, auditivos, paraplégicos, etc. Para portadores de necessidades especiais esta realidade se torna ainda mais importante, pois não serão excluídos da sociedade, que hoje vive essa nova era da informação e globalização, onde a tecnologia muda a cada instante. Por meio de um enfoque integrado da visão sistêmica, o presente estudo buscou compreender o projeto do Centro de Atendimento a Pessoas com Deficiências / SMAC (CAPD, procurando analisar como a tecnologia de informação pode transformar a vida sociocultural destes indivíduos. Para coleta de dados foram utilizadas entrevistas semi-estruturadas, que permitiram a avaliação das fases do desenvolvimento e as mudanças na realidade dos envolvidos. Foram identificados os fatores que comprovam a viabilidade e a eficiência das tecnologias quando inseridas na rotina dos deficientes e seus familiares. This study focuses how the information technology can assist people with disabilities that possess difficulties in the learning and reasoning, since the information technology, when used of planned and well structuralized form allows greater absorption of concepts and cultural growth. This growth aims to understand the formation of all kinds of disabilities - visual, mental, auditory, paraplegia etc. For people with disabilities this reality is more important, therefore they will not be excluded from the society, that currently lives this new age of the information and globalization, where the technology change at every moment.

    Full Text Available Resumo: O presente texto tem por objetivo relacionar a síndrome da alienação parental, o falso abuso sexual e a guarda compartilhada partindo, para tanto, de uma perspectiva transdisciplinar. Visa-se, assim, desvelar noções que são comuns tanto ao Direito como a Psicologia a partir de uma perspectiva diferenciada. Especificamente, busca-se observar tanto aspectos jus-normativos, como a postura psicossocial que cristaliza a alienação parental, observando seus efeitos, sobretudo, em relação ao falso abuso sexual e a guarda compartilhada. Com efeito, as consequências da alienação parental tornam-se mais radicalizadas e universalizadas em um contexto de modernidade tardia, trazendo a necessidade de uma análise que parta de um prisma complexo, que não obstrua as relações de solidariedade existentes entre o Direito e a Psicologia. Palavras-chave: Direito. Transdisciplinaridade. Alienação Parental. Falso Abuso Sexual. Guarda Compartilhada.

    Jorge Lyra

    Full Text Available Em nossa sociedade, percebe-se um crescimento da preocupação com a adolescência, sendo esta última representada não apenas como uma "fase da vida", mas um período, a priori, sempre problemático. O adolescente, por sua vez, tem sido visto como um sujeito de necessidades, por exemplo, de um atendimento de saúde específico. Na prática, entretanto, pouco se tem trabalhado com o adolescente como sujeito de direitos, a despeito do debate em torno do Estatuto da Criança e do Adolescente. Com base na crítica a esta postura, o presente artigo tem como objetivo apresentar uma experiência de pesquisa-intervenção de educação não-formal com um grupo de adolescentes de camadas baixas, na qual se procurou discutir noções correntes de adolescência, possibilitando um mapeamento e uma (reconstrução de outros sentidos.

    Full Text Available O presente trabalho tem por escopo analisar as transformações pelas quais o judiciário passa a partir da necessidade de efetivação dos direitos fundamentais. O Estado Democrático de Direito cunhado a partir do regramento normativo constitucional de 1988 faz erigir uma nova hermenêutica, qual seja, a hermenêutica constitucional. Para além do normativismo-positivista, essa hermenêutica constitucional irá atrelar valores à norma cujo principal e estruturante da própria ordem jurídica será o da dignidade da pessoa humana. A partir dessas modificações, os poderes públicos, o qual destacamos o judiciário, passam a ser imantados por esse imperativo ético, ou seja, o poder judiciário passa a ser uma importante ferramenta na concretização dos próprios direitos humanos fundamentais.

    Full Text Available Pesquisa descritiva exploratória que se propõe a investigara atuação do enfermeiro da Unidade de Terapia Intensiva, referenciando como este identifica, diagnostica e resolve os problemas ligados à segurança emocional dos clientes internados. O estudo abrangeu vinte e oito enfermeiros e dez clientes das unidades de três hospitais da Cidade do Rio de Janeiro. A técnica adotada para pesquisa consistiu da observação sistemática não participada. Os resultados obtidos demonstraram que os procedimentos terapêuticos dominantes recaem sobre alterações físicas em detrimento do emocional, evidenciando que o enfermeiro, ao distanciar-se de uma atuação holística, acarretará sérios prejuízos na assistência destes clientes, cuja necessidade humana básica afetada é predominantemente relacionada à segurança emocional.

    Full Text Available As pessoas com necessidades especiais apresentam maior risco para o surgimento de doenças bucais devido a situações biológicas, o uso sistemático de medicamentos, dificuldade na realização do controle de placa bacteriana e hábitos alimentares precários. O objetivo deste estudo foi analisar de forma descritiva os atendimentos odontológicos para pessoas com necessidades especiais na modalidade hospitalar no âmbito do Sistema Único de Saude (SUS. Foram estudados os procedimentos odontológicos realizados em ambiente hospitalar, a partir das internações geradas com finalidade de realizar tratamento odontológico em pacientes com necessidades especiais, informados no Sistema de Informação Hospitalar do SUS (SIH/ SUS no ano 2012. Foram registradas 6.691 Autorizações de Internação Hospitalar (AIH onde realizou-se 24.669 procedimentos dos quais 57,8% foram procedimentos clínicos. Dos procedimentos odontológicos realizados, 13,29% corresponderam a exodontias de dentes permanentes. Dessa forma, a atenção odontológica prestada aos usuários mostrouse positiva uma vez que a maioria dos procedimentos realizados foram clínicos preventivos e restauradores. Percebe-se ainda a necessidade de ampliação de acesso ao tratamento odontológico em pacientes com necessidades especiais no âmbito hospitalar e melhor distribuição já que a apresentação de mais da metade das AIH concentrou-se em três Estados.

    Full Text Available Trata-se de uma pesquisa qualitativa, com abordagem da fenomenologia social, realizada em 2010, com oito adolescentes que passaram pela experiência do aborto e foram atendidas em uma instituição hospitalar filantrópica de Minas Gerais. Objetivou-se, com ela, compreender a experiência e as necessidades de cuidado das adolescentes em situação de abortamento. Os resultados mostram que o impacto da gravidez levou-as ao medo da não aceitação da família e, ao mesmo tempo, à felicidade, pela possibilidade de ser mãe. A experiência do aborto foi marcada por sofrimento, e o atendimento foi considerado satisfatório, mas foi realçada a necessidade do recebimento de mais atenção e informação. As adolescentes planejam dar continuidade aos estudos e têm em vista a possibilidade de engravidar novamente. Vislumbram-se o planejamento de ações preventivas destinadas a este público e o desenvolvimento de novas investigações científicas que incluam a perspectiva de familiares e de profissionais de saúde.Se trata de una investigación cualitativa, con abordaje de la fenomenología social, realizada en 2010, con ocho adolescentes que experimentaron el aborto y fueron atendidas en un hospital de institución filantrópica del Estado de Minas Gerais.

    2003-01-01

    Full Text Available O artigo desenvolve um enfoque analítico voltado para o estudo do complexo industrial da saúde, englobando o conjunto das atividades produtivas e suas relações de interdependência, segundo uma perspectiva de economia política e da inovação. A lógica empresarial capitalista penetra em todos os segmentos produtivos, envolvendo tanto as indústrias que já operavam tradicionalmente nessas bases quanto segmentos que possuíam formas de organização em que era possível verificar a convivência de lógicas empresariais com outras que dela se afastavam, como a produção de vacinas e produtos biológicos, fitoderivados e a prestação de serviços de saúde. O artigo analisa a interação entre o sistema de saúde e o sistema econômico-industrial, mostrando como tem havido uma dicotomia na relação entre ambos, que se exprime na deterioração do potencial de inovação do país e numa crescente e preocupante vulnerabilidade externa da política de saúde. Sugere-se que o enfoque neoclássico tradicional da economia da saúde é insuficiente para tratar do complexo industrial da saúde, dada a intensidade do processo de mudança estrutural, e a necessidade de um enfoque teórico alternativo que incorpore a dinâmica de transformação econômica e institucional, de acumulação e de inovação.

    1995-06-01

    Full Text Available A racionalidade científica moderna, buscando superar a fundamentação metafísica do conhecimento objetivo, toma a experiência do fato particular como a atualização de leis dadas a priori na mente humana ou na natureza, constituindo, paradoxalmente, uma nova e 'intransparente' metafísica. Entre as críticas contemporâneas a esta forma de pensar e fazer ciência, delineia-se uma compreensão construtivista, segundo a qual o fato particular e seu conhecimento objetivo resultam de relações circunstanciais entre o homem e seu mundo. Revisitando alguns dos principais fundadores da ciência ocidental, como Aristóteles, Bacon, Descartes, Leibniz, Kant, Newton e Stuart Mill, este ensaio hermenêutico procura explorar a participação do metaconceito de 'necessidade' nessa dialética do conhecimento, interpretando, em termos epistemológicos, seu papel na construção e hipóstase da racionalidade científica moderna.Modern scientific rationality, seeking to move beyond the metaphysical foundations of objective knowledge, takes the experience of a particular fact to be the actual expression of prior laws of the human mind or of nature, thereby paradoxically constituting a new, 'invisible' metaphysics. Among contemporary critiques of this way of 'thinking and doing science', a constructivist understanding is gaining outline; according to this conception, a particular fact and objective knowledge thereof derive from circumstantial relations between human beings and their world. Revisiting some of the main founders of Western science, such as Aristotle, Bacon, Descartes, Leibniz, Kant, Newton, and Stuart Mill, this hermeneutic essay explores the participation of the meta-concept of 'necessity' within this dialectic of knowledge and, in epistemological terms, interprets its role in the construction and hypostatization of modern scientific rationality.

    Full Text Available Neste trabalho divulgam-se resultados de experiências em vasos em que membranas de troca aniónica (MTA foram inseridas directamente no solo para monitorar o teor de nitratos ao longo do tempo, e em que o estado nutritivo dasplantas foi avaliado através de um medidor de clorofila SPAD-502. Na estação quente foi cultivado milho e no período outono-inverno nabiça e centeio. O milho foi semeado a 5 de Junho de 2004 e a nabiça e o centeio a 23 de Setembro de 2004. As plantas foram sujeitas aos seguintes tratamentos fertilizantes: Nutrisoil (Nut; Beiraadubo (Bei; Phenix (Phe; e Vegethumus (Veg, quatro correctivos orgânicos comerciais; estrume de bovino (EB; casca de castanha (CC; nitrato de amónio (NA; e um tratamento sem azoto (T. Os resultados das MTA e os valores SPAD foram relacionados com a matéria seca produzida e o N exportado. Em Junho, na primeira amostragem, a concentração média de nitratos nos extractos das MTA variou entre 18,3 e 239,4 mg L-1, nos tratamentos CC e NA. Na primeira semana de Agosto, foram registados valores médios de nitratos no solo de 12,9 a 52,3 mg L-1 nos tratamentos CC e Bei. Na última amostragem, em Setembro, os valores médios de nitratos no solo variaram entre 9,7 e 67,9 mg L-1 nos tratamentos CC e Nut. As MTA revelaram boa capacidade para discriminar a forma como os diferentes fertilizantes libertaram o azoto ao longo do tempo e como este aspecto condicionou a absorção do nutriente e o desenvolvimento das plantas. Os valores SPAD revelaram-se bons indicadores do estado nutritivo azotado do milho, em condições em que foi possível controlar grande parte da variabilidade experimental. Os valores SPAD estiveram linearmente relacionados com a produção de matéria seca e o N exportado. Nas condições deste ensaio, em que a lixiviação e a desnitrificação foram controladas, as culturas intercalares centeio e nabiça recuperaram o N residual da cultura anterior até próximo do limite da sua

    Full Text Available Justificativa e objetivos: a solicitação indiscriminada de exames complementares na avaliação pré-anestésica é comum na prática clínica e implica custos adicionais e a possibilidade de resultados falso-positivos. Os objetivos desta pesquisa foram analisar se os exames pré-operatórios em cirurgias eletivas são solicitados segundo critério clínico e avaliar os custos desnecessários para a instituição. Métodos: foram avaliadas as solicitações de exames pré-operatórios em pacientes adultos submetidos a cirurgias eletivas não cardíacas. Os exames foram solicitados pelos cirurgiões, conforme protocolo do Serviço de Anestesia. Foram avaliados dados demográficos, estado físico, comorbidades e tipo de exame complementar solicitado. Os exames feitos foram comparados com os exames indicados. O custo dos exames foi baseado na tabela Datasus. Resultados: foram avaliados 1.063 pacientes. Verificou-se que 41,9% dos exames feitos nos pacientes classificados como ASA I não estavam indicados. No grupo de risco ASA II foram feitos 442 exames (17,72% sem necessidade. Perceberam-se elevadas porcentagens na solicitação de hemograma, creatinina, coagulograma, raios X de tórax e ECG nos grupos ASA I-II. Apenas 40 (5,25% dos exames feitos no grupo ASA III não estavam indicados. Nos pacientes do grupo ASA IV, 22,5% dos exames necessários não foram feitos. Ressalta-se uma economia anual de 13% (R$1.923,13 caso os exames fossem feitos conforme o protocolo. Conclusões: os exames pré-operatórios nem sempre são solicitados de acordo com critérios clínicos, o que resulta em maiores custos para a instituição.

O objetivo deste trabalho é, assim, conhecer as perceções dos pais relativamente à inclusão, assim como os factores que as influenciam. Para isso, foi aplicado um inquérito a 300 pais, com e sem filhos com necessidades educativas especiais. Os resultados permitiram perceber atitudes genericamente positivas, sem diferenças relativamente ao género e ao fato de serem pais de crianças com necessidades educativas especiais. Contudo as variáveis idade, escolaridade e proximidade / contato pareceram influenciar a perceção em relação a inclusão de crianças NEE. Assim, os pais com atitudes mais favoráveis à inclusão tendem a ser os mais novos, que tiveram proximidade / contato com criança NEE. Os resultados são discutidos em função da literatura.

Neste contexto investigou-se a seguinte questão de pesquisa:  Existe a necessidade de mudança na Lei 4320/64, na percepção dos técnicos, gestores e auditores do Tribunal de Contas do Município de São Paulo?  A pesquisa foi realizada através da aplicação de um questionário a vinte e um profissionais de Contabilidade, do município com funções de gestão, de operação e auditores do tribunal de contas. Pelas respostas obtidas verificou-se que, na percepção destes indivíduos, a Lei 4.320/64 carece de atualização. Outros aspectos como a complexidade da lei em relação ao tamanho de muitos municípios foram levantados, bem como a necessidade de uma interpretação uniforme da Lei. Os conflitos entre a Lei 4.320/64 e a Lei Complementar 101/00 são resolvidos, seguindo o que estabelece a LC 101/00, por ser mais recente. Foi colocado ainda que, na visão destes profissionais, a harmonização das práticas contábeis é inevitável também no setor público, posto o atual grau de globalização que vivemos.

Gadgets consistem em dispositivos tecnológicos que tem função específica e prática com grande utilidade no dia a dia como celulares, smartphones, leitores de MP3, dentre outros (SAID, et al, 2014. Dispositivos como esses auxiliam na ampliação das formas de comunicação que na maioria das vezes despertam desejos e necessidades dos consumidores. Para que haja aumento crescente deste tipo de tecnologia, a indústria utiliza a obsolescência programada. Trata-se de uma estratégia para reduzir o ciclo de vida dos produtos. Por meio da obsolescência programada a empresa diminui o tempo em os produtos permanecem em cada fase do ciclo de vida, que são: desenvolvimento, introdução, crescimento, maturidade e declínio. Essa estratégia, permite que as empresas consigam aumentar o consumo de gadgets pelos clientes e introduzir outros produtos/serviços inovadores no mercado. Para Silva (2012, produtos como gadgets já são produzidos para durar pouco tempo. Mont (2008 afirma que os principais elementos que estimulam o consumo no mercado são: maximização da produção, economia de escala, fabricação de produtos de qualidade mediana e vida curta, acelerado ciclo de depreciação e rápida substituição de bens, e a consequente crescente demanda dos consumidores por novos produtos e serviços. Sendo assim, o estudo sobre o comportamento de consumidores de gadgets, se torna relevante, pois permite entender a razão pela qual os consumidores compram os produtos por necessidade e/ou desejo. Para isso, foi realizado um estudo teórico sobre a Teoria das Necessidades de Maslow, que sugere a divisão dos elementos de satisfação do ser humano em cinco níveis diferentes em forma de pir

Apesar do disposto na constituição brasileira de 1988 quanto aos direitos dos índios e à preservação de suas culturas, setores da sociedade civil e Estado, seguidas vezes, demonstram encará-los como ameaças à unidade e à segurança nacional, quando situados em áreas de fronteira; ou como entraves ao desenvolvimento nacional. Identifica três linhas básicas de pensamento face à questão indígena: em favor da integração (compulsória ou não dos índios, a que defende os direitos a uma cultura diferente da hegemônica e uma terceira, à qual dá destaque.

    2013-09-01

    Full Text Available Desde que autores como Germani (1962, Di Tella (1969 e Ianni (1975 aplicaram a noção de populismo à América Latina, muito se escreveu sobre o tema. O conceito se estirou tanto que tem servido para definir políticos os mais díspares. Com a ausência das condições socioeconômicas descritas pelas formulações clássicas, a estratégia adotada é limitar a categoria à dimensão política. Esse procedimento, porém, não é capaz de descrever atributos exclusivos suficientes para que o populismo seja um fenômeno específico. Ao mesmo tempo, o conceito está tão enraizado que não é viável abandoná-lo. A solução proposta é avaliar em quais características um político se aproxima e se afasta dos casos paradigmáticos do passado. Assim, ele pode ser populista em certos aspectos e não em outros. Com esse procedimento, se chega a uma classificação, em que um líder apresente mais ou menos atributos descritos pelas definições clássicas, eliminando a necessidade de reformulação constante do conceito para adaptá-lo a novas circunstâncias. Também haveria menos espaço a que o rótulo de populista continuasse servindo para desqualificar políticos latino-americanos. O artigo aborda definições clássicas e recentes aplicadas à América Latina e avalia a viabilidade empírica da estratégia de se concentrar na dimensão política. --- LA APLICACIÓN DEL CONCEPTO DE POPULISMO AMÉRICA LATINA: la necesidad de clasificar, y no descalificar   Desde que autores como Germani (1962, Di Tella (1969 y Ianni (1975 aplicaron la noción de populismo a la América Latina, mucho se ha escrito sobre el tema.

O solo foi amostrado de forma convencional (amostra composta e sistemática (mediante uso de grade amostral, na profundidade de 0-0,2 m. Posteriormente à análise de fertilidade de rotina, determinaram-se as necessidades de calagem segundo os métodos do tampão SMP, da neutralização de alumínio e elevação do Ca e Mg, e da saturação por bases. Após análise descritiva, foram obtidos os semivariogramas e os mapas por krigagem. Ausência de dependência espacial, assim como da necessidade de aplicação do corretivo calcário foram observadas para o método da neutralização de Al. A dependência espacial foi encontrada para os atributos de acidez do solo e para as necessidades de calagem calculadas pelos métodos de saturação por bases e pH SMP, com alcances variando entre 35,7 e 200,5 m. Esses últimos mostraram também, uma coincidência regionalizada entre as maiores demandas de calcário. Os resultados permitiram evidenciar a existência de zonas de aplicação de calcário diferenciadas, quando consideradas a variabilidade dos atributos de acidez do solo no cálculo espacializado da dose e o tipo de corretivo calcário a ser utilizado.

A literatura descreveu que a primeira etapa para a implementação da tecnologia assistiva na escola deve permitir entender a situação que envolve o aluno a fim de ampliar a sua participação no processo de ensino e aprendizagem. Este estudo teve como objetivo identificar as necessidades de serviços, recursos e estratégias de tecnologia assistiva para o aluno com paralisia cerebral na escola. Foram selecionadas duas crianças com paralisia cerebral e seus professores. A etapa da coleta de dados contou com três procedimentos sucessivos: entrevista com os professores, preenchimento do protocolo de identificação da rotina escolar e observação dos participantes em sala de aula realizada através de filmagens e diário de campo. A partir dos três procedimentos, foi proposta a triangulação de dados, ou seja, agrupamento das informações obtidas em um único documento para o estabelecimento das categorias de análises. Após elaboração do material, as categorias foram apreciadas por juízes da área. Os resultados demonstraram que após entender a situação do aluno com deficiência no contexto escolar foi possível estabelecer as suas habilidades e necessidades para indicar os recursos de Tecnologia Assistiva adequados ao planejamento do professor e propiciar a aprendizagem da criança com deficiência.

Segundo vários autores, este modelo teórico pode fornecer informações importantes sobre o processo motivacional dos alunos para as aulas de Educação Física, no entanto, em Portugal não existe ainda nenhum instrumento de avaliação das necessidades psicológicas básicas neste contexto. Desta forma, o objectivo principal deste estudo é a validação preliminar da adaptação à Educação Física da versão Portuguesa do Basic Psychological Needs Exercise Scale (BPNESp, determinando as suas qualidades psicométricas iniciais através de uma análise factorial exploratória do modelo que a suporta. Para tal, participaram no estudo 150 alunos (n = 150 do 2º e 3º CEB, com idades compreendidas entre os 11 e 16 anos (M = 13.39, DP = 1.44 e com diferentes níveis de prática desportiva.

A análise dos dados indicou a importância da interação entre pares no processo de desenvolvimento das crianças com necessidades especiais e revelou a situação de brincadeira como espaço favorável para a construção dessas interações.The present study discussed the role of peer interaction, in a free-play situation, to the development of children with special needs. The interactions between visually impaired children (low vision or blindness, most of them with additional organic problems and/or learning difficulties, were observed in a free-play situation. The investigation of episodes which were representative of different abilities of the children lead to the identification of two categories: (a ways of playing (individually or in group, and (b kinds of relationships between peers (friendly or agonistic. The analysis pointed to peer interaction as an important contributing factor to the development of children with special needs and suggested that free-play situations can constitute favorable settings for the construction of those interactions.

    In this debate the Government's policy on nuclear power is discussed. Government policy is that nuclear power is the safest and cleanest way of generating electricity and is cheap. Other political parties who do not endorse a nuclear energy policy are considered not to be acting in the people's best interests. The debate ranged over the risks from nuclear power, the UK safety record, safety regulations, and the environmental effects of nuclear power. The Torness nuclear power plant was mentioned specifically. The energy policy of the opposition parties is strongly criticised. The debate lasted just over an hour and is reported verbatim. (UK)

Este estudo teve por objetivo comparar a descrição de professores de meninos e meninas identificados por eles como alunos com necessidades educacionais especiais. Os dados foram coletados a partir da coleção de 351 cadastros de alunos identificados como especiais. Esses cadastros fazem parte de um banco de dados iniciado em 2001 por um grupo de pesquisa e contém descrições espontâneas dos professores sobre as características das crianças que, segundo eles, justificavam a notificação. Tais descrições foram divididas em unidades de conteúdo e categorizadas. A freqüência em cada uma das categorias foi computada para os grupos, que foram divididos em função do gênero. Dos 351 cadastros, 66,1% referiam-se a crianças do sexo masculino, enquanto 33,9% eram de crianças do sexo feminino. A comparação da incidência das categorias nos dois grupos apontou como única diferença estatisticamente significativa: a indicação de meninos com base na categoria Problemas de Comportamento. Teorias explicativas existentes na literatura sobre viés de gênero na elegibilidade de meninos e meninas pelos seus respectivos professores são discutidas, bem como são apontadas as implicações científicas e a necessidade de mecanismos de monitoração deste tipo de viés que vem sendo sustentado pela área de Educação Especial e que contribuem para a construção de desigualdades sociais.Why are more boys than girls regarded by their teachers as being students with special needs (2 out of 3 are boys?

A metodologia utilizada baseou-se numa estratégia de sondagem assente na realização de um questionário que compreendeu a caracterização dos elementos de estudo, a estruturação das atitudes e o tipo de representações sociais dos educadores de infância nas escolas regulares, o enquadramento legal e a viabilidade do processo inclusivo e os recursos físicos humanos. Para interpretar os dados do questionário foi realizada uma análise estatística univariada e uma análise de conteúdos. A promoção da igualdade de oportunidades, a inter-ajuda e o paradigma da escola inclusiva, estão na origem de uma atitude favorável ao processo de inclusão de crianças com necessidades educativas especiais, que é condicionada pelos meios técnicos e humanos e condições físicas nas escolas. A representação social é em geral favorável ao processo de inclusão, apesar haver ainda discriminação das crianças com necessidades educativas, devido à falta de informação, de educação e de regras sociais, à classe social e nível econômico, a dificuldades de aceitação da diferença e das limitações físicas e à falta de higiene.This study determines the social representations of kindergarten teachers in the city of Évora, southern Portugal, on the inclusion of children with special educational needs in regular schools.

    Nuclear forensics is the analysis of nuclear materials recovered from either the capture of unused materials, or from the radioactive debris following a nuclear explosion and can contribute significantly to the identification of the sources of the materials and the industrial processes used to obtain them. In the case of an explosion, nuclear forensics can also reconstruct key features of the nuclear device. Nuclear forensic analysis works best in conjunction with other law enforcement, radiological protection dosimetry, traditional forensics, and intelligence work to provide the basis for attributing the materials and/or nuclear device to its originators. Nuclear forensics is a piece of the overall attribution process, not a stand-alone activity

Neste panorama, se para a medicina e as ciências psi (psiquiatria, psicologia e psicanálise a transexualidade constitui uma desordem mental, para alguns autores que discutem as experiências trans, em especial nas ciências sociais e humanas e na saúde coletiva, estas são vivências que colocam em questão as normas de gênero que regem nossos conceitos de sexo, gênero e, no limite, de humano. Todavia, a despeito das críticas acadêmicas e do movimento mundial em prol da despatologização das identidades trans, no contexto brasileiro ainda vigora uma interpretação patologizada destas vivências que não apenas sustenta sua definição como um transtorno psiquiátrico como orienta as políticas públicas destinadas a este segmento.

    The committee concludes that the nature of the proliferation problem is such that even stopping nuclear power completely could not stop proliferation completely. Countries can acquire nuclear weapons by means independent of commercial nuclear power. It is reasonable to suppose if a country is strongly motivated to acquire nuclear weapons, it will have them by 2010, or soon thereafter, no matter how nuclear power is managed in the meantime. Unilateral and international diplomatic measures to reduce the motivations that lead to proliferation should be high on the foreign policy agenda of the United States. A mimimum antiproliferation prescription for the management of nuclear power is to try to raise the political barriers against proliferation through misuse of nuclear power by strengthening the Non-Proliferation Treaty, and to seek to raise the technological barriers by placing fuel-cycle operations involving weapons-usable material under international control. Any such measures should be considered tactics to slow the spread of nuclear weapons and thus earn time for the exercise of statesmanship. The committee concludes the following about technical factors that should be considered in formulating nuclear policy: (1) rate of growth of electricity use is a primary factor; (2) growth of conventional nuclear power will be limited by producibility of domestic uranium sources; (3) greater contribution of nuclear power beyond 400 GWe past the year 2000 can only be supported by advanced reactor systems; and (4) several different breeder reactors could serve in principle as candidates for an indefinitely sustainable source of energy

    2010-01-01

    This review discusses the methodology of nuclear forensics and illicit trafficking of nuclear materials. Nuclear forensics is relatively new scientific branch whose aim it is to read out material inherent from nuclear material. Nuclear forensics investigations have to be considered as part of a comprehensive set of measures for detection,interception, categorization and characterization of illicitly trafficking nuclear material. Prevention, detection and response are the main elements in combating illicit trafficking. Forensics is a key element in the response process. Forensic science is defined as the application of a broad spectrum of sciences to answer questions of interest to the legal system. Besides, in this study we will explain age determination of nuclear materials.

    2011-01-01

    Nuclear fuel is a material that can be consumed to derive nuclear energy, by analogy to chemical fuel that is burned for energy. Nuclear fuels are the most dense sources of energy available. Nuclear fuel in a nuclear fuel cycle can refer to the fuel itself, or to physical objects (for example bundles composed of fuel rods) composed of the fuel material, mixed with structural, neutron moderating, or neutron reflecting materials. Long-lived radioactive waste from the back end of the fuel cycle is especially relevant when designing a complete waste management plan for SNF. When looking at long-term radioactive decay, the actinides in the SNF have a significant influence due to their characteristically long half-lives. Depending on what a nuclear reactor is fueled with, the actinide composition in the SNF will be different. The following paper will also include the uses. advancements, advantages, disadvantages, various processes and behavior of nuclear fuels

    Nuclear lamins are intermediate filament proteins that represent important structural components of metazoan nuclear envelopes (NEs). By combining proteomics and superresolution microscopy, we recently reported that both A- and B-type nuclear lamins form spatially distinct filament networks at the nuclear periphery of mouse fibroblasts. In particular, A-type lamins exhibit differential association with nuclear pore complexes (NPCs). Our studies reveal that the nuclear lamina network in mammalian somatic cells is less ordered and more complex than that of amphibian oocytes, the only other system in which the lamina has been visualized at high resolution. In addition, the NPC component Tpr likely links NPCs to the A-type lamin network, an association that appears to be regulated by C-terminal modification of various A-type lamin isoforms. Many questions remain, however, concerning the structure and assembly of lamin filaments, as well as with their mode of association with other nuclear components such as peripheral chromatin.

The minimum ethnopharmacological research team should consist of a botanist, a chemist and a pharmacologist with each carrying the responsibility for answering in sequential fashion critical questions. The chemical composition and pharmacological properties of the very efficient medicinal plant Croton cajucara were investigated according to ethnopharmacological approaches. The study with this Croton proved to be both efficient and successful. This happy situation was only possible because a multidisciplinary team was involved getting the research done correctly. The ethnopharmacological study involving one other especies Copaifera will be cited.

    1987-01-01

    This book raises pointed questions about nuclear saber rattling. More than a dozen cases since the bombing of Hiroshima and Magasaki in which some sort of nuclear threat was used as a sparring technique in tense confrontations are cited. Each incident is described and analyzed. Two theories offered to explain America's use of nuclear threats, the balance of interest theory and the balance of power theory, are contrasted throughout the book. This book helps to fill the gap in the understanding of nuclear weapons and their uses, while pointing out that nuclear bravado could lead to an unintended unleashing of these weapons

    We all want to prevent the use of nuclear weapons. The issue before us is how best to achieve this objective; more specifically, whether the peaceful applications of nuclear energy help or hinder, and to what extent. Many of us in the nuclear industry are working on these applications from a conviction that without peaceful nuclear energy the risk of nuclear war would be appreciably greater. Others, however, hold the opposite view. In discussing the subject, a necessary step in allaying fears is understanding some facts, and indeed facing up to some unpalatable facts. When the facts are assessed, and a balance struck, the conclusion is that peaceful nuclear energy is much more part of the solution to preventing nuclear war than it is part of the problem

    In 1998, Nuclear Regulatory Authority of the Slovak Republic (NRA SR) performed 38 inspections, 25 of them were performed in co-operation with IAEA inspectors. There is no fresh nuclear fuel at Bohunice A-1 NPP at present. Fresh fuel of Bohunice V-1 and V-2 NPPs is inspected in the fresh fuel storage.There are 327 fresh fuel assemblies in Mochovce NPP fresh fuel storage. In addition to that, are also 71 small users of nuclear materials in Slovakia. In most cases they use: covers made of depleted uranium for non-destructive works, detection of level in production plants, covers for therapeutical sources at medical facilities. In. 1995, NRA SR issued 4 new licences for nuclear material withdrawal. In the next part manipulation with nuclear materials, spent fuel stores and illegal trafficking in nuclear materials are reported

    Written from the basis of neutrality, neither for nor against nuclear power this book considers whether there are special features of nuclear power which mean that its development should be either promoted or restrained by the State. The author makes it dear that there are no easy answers to the questions raised by the intervention of nuclear power but calls for openness in the nuclear decision making process. First, the need for energy is considered; most people agree that energy is the power to progress. Then the historicalzed background to the current position of nuclear power is given. Further chapters consider the fuel cycle, environmental impacts including carbon dioxide emission and the greenhouse effect, the costs, safety and risks and waste disposal. No conclusion either for or against nuclear power is made. The various shades of opinion are outlined and the arguments presented so that readers can come to their own conclusions. (UK)

    This chapter of the final report of the Royal Commission on Electric Power Planning in Ontario updates its interim report on nuclear power in Ontario (1978) in the light of the Three Mile Island accident and presents the commission's general conclusions and recommendations relating to nuclear power. The risks of nuclear power, reactor safety with special reference to Three Mile Island and incidents at the Bruce generating station, the environmental effects of uranium mining and milling, waste management, nuclear power economics, uranium supplies, socio-political issues, and the regulation of nuclear power are discussed. Specific recommendations are made concerning the organization and public control of Ontario Hydro, but the commission concluded that nuclear power is acceptable in Ontario as long as satisfactory progress is made in the disposal of uranium mill tailings and spent fuel wastes.

    Is a nuclear power renaissance likely to occur in the United States? This paper investigates the many driving forces that will determine the answer to that question. This analysis reveals some frequently overlooked truths about the current state of nuclear technology: An examination of the issues also produces some noteworthy insights concerning government regulations and related technologies. Public opinion will play a major role in the unfolding story of the nuclear power renaissance. Some observers are betting that psychological, sociological, and political considerations will hod sway over public attitudes. Others wager that economic and technical concerns will prevail. The implications for the nuclear power renaissance are striking

    The Brazilian standard ABNT ISO/IEC 17025/2005 specifies general requirements for the competence of testing and calibration facilities. One of these requirements states that these facilities must always optimize their processes and thus, uncertainties must be estimated and lowered as much as possible. In order to achieve such goal, the Laboratorio de Calibracao de Instrumentos (LCI), a laboratory responsible for dosimeter calibration at the Instituto de Pesquisas Energeticas e Nucleares (IPEN/CNEN) have acquired some equipment for the LCI's X-Ray calibration system, such as a rotating filter holder, and it has also been developing software in order to provide the best calibration results with lowest external interferences (from the operator, for instance) to diminish the possibilities of error occurrences. A semi-automated LabVIEW-based calibration software has been developed at LCI and it has been subjected to constant testing and improvements so far. The software is divided in two basic modules: one is responsible for calibration of the monitor chamber with a reference standard dosimeter, while the other is used to perform instruments calibrations using the monitor chamber as reference. Several influence quantities have been analyzed and the proper corrections have been added to the software as multiplicative correction factors. The software is not only able to acquire data from all the equipment used in the laboratory, but also it is able to calculate calibration factors and its uncertainties. A later analysis shows how this system has optimized the whole calibration process, lowering the occupational dose, reducing the mean time of calibration, uncertainties and preventing errors caused by the system's users.

As chamadas diretrizes para a “educação das relações raciais” como sintomaticamente vem sendo chamada pelos ativistas do movimento negro, e acadêmicos, colocam para além da questão racial a necessidade de ensinar história e cultura afro-brasileira e africana. Meu objetivo no presente texto é argumentar que a ênfase na “educação das relações raciais” restringe o escopo das diretrizes ao limitar seu horizonte à política de satisfação de necessidades (politics of fulfilment que, de acordo com Gilroy (1993, tem sido praticada pelos descendentes de escravos, demandando da sociedade civil burguesa que cumpra as promessas de sua própria retórica. Em outras palavras, ela cria os meios nos quais demanda por objetivos como uma justiça não racializada e uma organização dos processos produtivos. A sua expressão máxima é a política do reconhecimento intersecionada com a política redistributiva. Em contraste, com a política de satisfação de necessidades, Gilroy

    The D-T fusion cross-section is calculated using quantum mechanics with the model of square nuclear potential well and Coulomb potential barrier. The agreement between ENDF data and the theoretically calculated results is well in the range of 0.2-280 keV. It shows that the application of Breit-Wigner formula is not suitable for the case of the light nuclei fusion reaction. When this model is applied to the nuclear reaction between the charged particles confined in a lattice, it explains the 'abnormal phenomena'. It implies a prospect of nuclear fusion energy without strong nuclear radiations

    1987-01-01

    A great deal of attention has been paid in the past decade or so to the characteristics of terrorists and their apparent goals and objectives, capabilities, and evolving strategy and tactics with respect to nuclear terrorism. In contrast, little has been said about the procedural aspects of nuclear terrorism, and even less about the way in which such endeavors can fail. This latter omission is important because it bears directly on the ability to evaluate credibly the potential for nuclear terrorism. Here, the author addresses the requirements inherent in acquiring a nuclear explosive capability by three routes: separation of plutonium from irradiated light or heavy water reactor (LWR or HWR) fuel, processing, or use of separated fissile material, and theft of a nuclear weapon. In addition, he deals with other potential acts of nuclear terrorism: sabotage of power reactors, uranium enrichment facilities and spent nuclear fuel in transport, and dispersal of radioactive materials, in particular, plutonium. He specifically does not look at the design or production of a nuclear weapon. Finally, the discussion here assumes that the terrorist is subnational; that is, a nation is not involved. Also, the discussion of subnational participation does not address the possibility of collusion with insiders

    2005-01-01

    Nuclear measurements play a fundamental role in the development of nuclear technology and the assurance of its peaceful use. They are also required in many non-power nuclear applications such as in nuclear medicine, agriculture, environmental protection, etc. This presentation will show examples of most recent advances in measurement methodology or technology in the areas described below. The Generation IV International Forum has selected six innovative reactor systems as candidates for a next generation of sustainable, economic and safe nuclear energy systems. The choice of the best options relies heavily on the availability of accurate nuclear data that can only be obtained, in an international effort, using highly specialised facilities. Significant efforts are being directed towards the partitioning and transmutation of highly active nuclear waste. Different concepts involving fast reactors or accelerator-driven systems are being studied in view of their transmutation capabilities. State of the art equipment has been developed to assess basic properties of nuclear fuel at very high burn-up; some fine examples of this work will be shown. Physical and chemical methods play a crucial role in the detection and identification of radioisotopes used in various stages of the nuclear fuel cycle. Radiation measurement techniques are used, for example, to monitor the quantities of uranium, plutonium and other actinide elements in fuel enrichment and reprocessing facilities. Another field of application of physical and chemical methods is the characterisation of nuclear material seized from illicit trafficking. Seized material has to be analysed in order to obtain clues on its origin and intended use and to prevent diversion of nuclear material from the same source in the future. A recent highlight in basic physics relates to nuclear fission and transmutation with high intensity lasers. Ultra-fast high intensity lasers can produce high energy (tens of MeV) photons through

    Nuclear energy has found many applications in space projects. This article deals with these applications. The first application is the use of nuclear energy for the production of electricity in space and the second main application is the use of nuclear energy for propulsion purposes in space flight. The main objective is to develop a 75000 pound thrust flight engine call NERVA by heating liquid hydrogen, in a nuclear reactor, from 420F to 4000 0 F. The paper describes in detail the salient features of the NERVA rocket as well as its comparison with the conventional chemical rockets. It is shown that a nuclear rocket using liquid hydrogen as medium is at least 85% more efficient as compared with the chemical rockets such as those used for the APOLLO moon flight

    Nuclear techniques have been applied to study diagnose and treat various haematological disorders for more than five decades. Two scientists are regarded as pioneers in this field, i.e. John Lawrence who in 1938 used 32 P to treat chronic myeloid leukaemia and George Hevessy who used 32 P labelled erythrocytes to measure blood volume in 1939. At present, many nuclear medicine procedures are available for diagnosis and therapy of a variety of haematological disorders. Although nuclear techniques are somewhat complex, they give direct and quantitative assessment of the kinetics of blood elements as compared to other non-isotopic haematological tests. Basically, equipment required for nuclear haematology is very simple such as well scintillation counters to measure radioactivity in blood samples. More sophisticated equipment like rectilinear scanner or gamma camera is required when imaging is necessary. An overview of the basic principles and clinical applications of nuclear haematology is given

    Increasing threat by terrorists for a possible nuclear attack is particularly alarming in recent years. The likelihood of such an event is highly uncertain but cannot be ruled out. The consequence of such an event would be highly disastrous and the implications could be far-reaching both socially and politically. It is feared that significant amount of nuclear weapons materials may be kept under poor security. Therefore, there is a greater demand with utmost priority to curb nuclear terrorism by adapting proper security measures. One of the most important measures is to stop illicit trafficking of nuclear materials which are the source of building nuclear explosive devices. According to the IAEA illicit trafficking database (ITDB) report, a total number of 252 incidents were reported in 2006, of which 150 occurred in 2006 and the remaining 102 had taken place prior to that year, mainly in 2005

    In this short paper it has only been possible to deal in a rather general way with the standards of safety used in the UK nuclear industry. The record of the industry extending over at least twenty years is impressive and, indeed, unique. No other industry has been so painstaking in protection of its workers and in its avoidance of damage to the environment. Headings are: introduction; how a nuclear power station works; radiation and its effects (including reference to ICRP, the UK National Radiological Protection Board, and safety standards); typical radiation doses (natural radiation, therapy, nuclear power programme and other sources); safety of nuclear reactors - design; key questions (matters of concern which arise in the public mind); safety of operators; safety of people in the vicinity of a nuclear power station; safety of the general public; safety bodies.

    The terms and reactions to President Carter's nuclear policy, culminating in the 1978 Nuclear Non-Proliferation Act, are reviewed and analyzed. The new law increases restrictions on nuclear exports, encourages continued use of light water reactors in preference to plutonium-fueled reactors, and emphasizes technical solutions to proliferation problems. Critics of the law point out that it will hurt U.S. trade unfairly, that other countries do not have as many fuel options as the U.S. has, and that nuclear sales have as many political and economic as technical solutions. Compromise areas include new international safety guidelines, the possibility of an international nuclear fuel bank, and a willingness to consider each case on its merits. 21 references

    The United Kingdom government announced in May 1995 plans to privatize the country's two nuclear generating companies, Nuclear Electric and Scottish Nuclear. Under the plan, the two companies will become operating divisions of a unified holding company, to be called British Electric, with headquarters in Scotland. Britain's nuclear plants were left out of the initial privatization in 1989 because the government believed the financial community would be unwilling to accept the open-ended liability of decommissioning the original nine stations based on the Magnox gas-cooled reactor. Six years later, the government has found a way around this by retaining these power stations in state ownership, leaving the new nuclear company with the eight Advanced Gas-cooled Reactor (AGR) stations and the recently completed Sizewell B PWR stations. The operating Magnox stations are to be transferred to BNFL, which operates two Magnox stations of their own at Calder Hall and Chapelcross

    The future of nuclear power has returned to centre stage. Freezing weather on both sides of the Atlantic and last month's climate-change talks in Montreal have helped to put energy and the future of nuclear power right back on the political agenda. The issue is particularly pressing for those countries where existing nuclear stations are reaching the end of their lives. In the UK, prime minister Tony Blair has commissioned a review of energy, with a view to deciding later this year whether to build new nuclear power plants. The review comes just four years after the Labour government published a White Paper on energy that said the country should keep the nuclear option open but did not follow this up with any concrete action. In Germany, new chancellor and former physicist Angela Merkel is a fan of nuclear energy and had said she would extend the lifetime of its nuclear plants beyond 2020, when they are due to close. However, that commitment has had to be abandoned, at least for the time being, following negotiations with her left-wing coalition partners. The arguments in favour of nuclear power will be familiar to all physicists - it emits almost no carbon dioxide and can play a vital role in maintaining a diverse energy supply. To over-rely on imported supplies of oil and gas can leave a nation hostage to fortune. The arguments against are equally easy to list - the public is scared of nuclear power, it generates dangerous waste with potentially huge clean-up costs, and it is not necessarily cheap. Nuclear plants could also be a target for terrorist attacks. Given political will, many of these problems can be resolved, or at least tackled. China certainly sees the benefits of nuclear power, as does Finland, which is building a new 1600 MW station - the world's most powerful - that is set to open in 2009. Physicists, of course, are essential to such developments. They play a vital role in ensuring the safety of such plants and developing new types of

    Do we need nuclear energy. Is it safe. What are the risks. Will it lead to proliferation. The questions are endless, the answers often confused. In the vigorous debates that surround the siting and operation of nuclear power plants, it is all too easy to lose sight of the central issues amid the mass of arguments and counter-arguments put forward. And there remains the doubt, who do we believe. This book presents the facts, simply, straightforwardly, and comprehensibly. It describes the different types of nuclear reactor, how they work, how energy is produced and transformed into usable power, how nuclear waste is handled, what safeguards are built in to prevent accident, contamination and misuse. More important, it does this in the context of the real world, examining the benefits as well as the dangers of a nuclear power programme, quantifying the risks, and providing an authoritative account of the nuclear industry worldwide. Technically complex and politically controversial, the contribution of nuclear energy to our future energy requirements is a crucial topic of our time. (author)

  11. Nuclear Hostages

    International Nuclear Information System (INIS)

    Cooper, C.L.

    1978-01-01

    The global spread of nuclear reactors for the production of energy seems inevitable. Nuclear power plants will be supplied--if not by the United States, then by one of several other exporters. But other aspects of this development are less certain. One is the relationship between proliferation of nuclear energy plants and that of nuclear weapons. Another is the actual constraint that such vulnerable potential targets as nuclear power plants would have on would-be aggressors. In the last analysis, this would depend on the rationality of a nation's leadership. What can be said for the concept of nuclear power plants as potential hostages is that by installing a reactor on its territory, a country increases its vulnerability to grave, possibly unacceptable damage in the event of war. As a result, that nation's leaders might be inclined to raise the threshold of their sensitivity to provocation by neighbors and to restrain their own inclinations toward aggression. Admittedly this is a frail substitute for robust international agreements, but in the present order of things it is not a trivial consideration. Many incidents once regarded by the great powers as easi belli have more recently been either resolved by diplomacy or ignored altogether. The idea must not be pressed too far. The export of a nuclear power plant to a Third World country cannot be advocated simply as a means to constrain its own military adventurism. Aside from the promise of a vast increase in energy supply for developing nations, nuclear powered generating stations could actually improve relations among countries. The risk of widespread radioactive contamination by nuclear power plants hit by even conventional bombs could introduce a positive new element into the military calculations of powers outside the NATO-Warsaw Pact arena. As they balance military and diplomatic solutions to local conflicts, moderation rather than bellicosity might become the better part of valor

    Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive materials to examine organ function and structure. Nuclear medicine is older than CT, ultrasound and MRI. It was first used in patients over 60-70 years ago. Today it is an established medical specialty and offers procedures that are essential in many medical specialities like nephrology, pediatrics, cardiology, psychiatry, endocrinology and oncology. Nuclear medicine refers to medicine (a pharmaceutical) that is attached to a small quantity of radioactive material (a radioisotope). This combination is called a radiopharmaceutical. There are many radiopharmaceuticals like DTPA, DMSA, HIDA, MIBI and MDP available to study different parts of the body like kidneys, heart and bones etc. Nuclear medicine uses radiation coming from inside a patient's body where as conventional radiology exposes patients to radiation from outside the body. Thus nuclear imaging study is a physiological imaging, whereas diagnostic radiology is anatomical imaging. It combines many different disciplines like chemistry, physics mathematics, computer technology, and medicine. It helps in diagnosis and to treat abnormalities very early in the progression of a disease. The information provides a quick and accurate diagnosis of wide range of conditions and diseases in a person of any age. These tests are painless and most scans expose patients to only minimal and safe amounts of radiation. The amount of radiation received from a nuclear medicine procedure is comparable to, or often many times less than, that of a diagnostic X-ray. Nuclear medicine provides an effective means of examining whether some tissues/organs are functioning properly. Therapy using nuclear medicine in an effective, safe and relatively inexpensive way of controlling and in some cases eliminating, conditions such as overactive thyroid, thyroid cancer and arthritis. Nuclear medicine imaging is unique because it provides doctors with

    Since the end of the East-West confronting, the nuclear weapon issue has been focused in an international debate with obvious repercussions in Europe, because it is the European continent which indicated first the significance of nuclear deterrence. This debate refers first upon the past, as the German unification allowed capturing numerous documents of Warsaw treaty which revealed the intentions and the plans of Soviet Union during the cold war, and secondly concerns the future, since the role of nuclear weapons must be re-thought in a new context. This is the subject of this book, which refers also to the problem of the nuclear proliferation in the world and evolution of different countries in a political and regional context. The extension of the non-proliferation treaty for an undefined duration, in May 1995, is a incontestable victory because this treaty rules the renouncement to nuclear weapons of 185 countries. However, it does not solve most sensible problems like the Iraq case, for which a specific inspection regime has been instituted, or the case of Iran, which is suspected to acquire the bomb, although no clear evidence has been provided up to now. This is also the case of Israel, India and Pakistan which allege plainly their willingness of keeping open, from security reasons, their nuclear option. The content is displayed in five chapters: 1. Introduction; 2. The role of the nuclear weapons after the cold war; 3. The nuclear proliferation at crossroads; 4. Undefined extension of the NPT, a striking but fragile victory; 5. Conclusions.

    Today we know two forms of nuclear energy: fission and fusion. Fission is the decomposition of heavy nuclei, while fusion is the melting together of light nuclei. Both processes create a large surplus of energy. Technologically, we can currently only use fission to produce energy in today's nuclear power plants, but there is intense research worldwide in order to realize a controlled fusion process. In a practical context, today's nuclear energy is a sustained source of energy since the resource base is virtually unlimited. When fusion technology is realized, the resource supply will be a marginal problem. (AG)

Para atingir este objetivo é preciso ter presente dois aspectos imprescindíveis de desenvolvimento: em primeiro lugar, Hegel começa por desenvolver, num primeiro tempo, o alcance geral de efetividade - a exposição do absoluto, o atributo e o modo do absoluto2, é o sentido do primeiro capítulo - e continua, em segundo lugar, pela exposição dos três momentos da efetividade como tal3, a possibilidade, a contingência e a necessidade - é o objetivo do segundo capítulo, da terceira seção da lógica da essência de Hegel. No presente artigo, sugere-se que somente este último pode fundamentar uma reflexão filosófica, assim como foi desenvolvida pelo filósofo alemão, G.W.F. Hegel, e utilizá-la para uma compreensão sistemática deste aspecto central da Ciência da Lógica, a efetividade possibilita contribuir com as pesquisas em problemas e teorias da Filosofia Moderna e Contemporânea, na medida em que explicita a rede conceitual hegeliana da categoria de efetividade e atualiza seu potencial interpretativo, construindo perspectivas epistemológicas e metodológicas inovadoras, o que é próprio da pesquisa e interdisciplinaridade. Identidade do interior e do exterior que constitui a efetividade é uma forma de imediatidade. A efetividade define-se como unidade imediata da essência e da existência.

    The energy demand complexion of this country is always changing and promises to change in the future. The nuclear industry is responding to changing energy demands through standards writing activities. Since the oil embargo of 1973, there has been a change in the mix of fuels contributing to energy growth in this country; virtually all of the energy growth has come from coal and nuclear power. The predicted expansion of coal use by 1985, over 1977 level, is 37%, while the use of oil is expected to decline by 17%. Use of nuclear power is expected to increase 62% from the 1977 level. The feasibility of using nuclear energy to meet the needs of the USA for electric power is discussed

    The author proposes an overview of methods and concepts used in the nuclear industry, at the design level as well as at the exploitation level, to ensure an acceptable safety level, notably in the case of nuclear reactors. He first addresses the general objectives of nuclear safety and the notion of acceptable risk: definition and organisation of nuclear safety (relationships between safety authorities and operators), notion of acceptable risk, deterministic safety approach and main safety principles (safety functions and confinement barriers, concept of defence in depth). Then, the author addresses the safety approach at the design level: studies of operational situations, studies of internal and external aggressions, safety report, design principles for important-for-safety systems (failure criterion, redundancy, failure prevention, safety classification). The next part addresses safety during exploitation and general exploitation rules: definition of the operation domain and of its limits, periodic controls and tests, management in case of incidents, accidents or aggressions

    1989-01-01

    This chapter present a brief overview of the current situation of siting radioactive wastes. This is followed by an overview of various psychological approaches attempting to analyse public reactions to nuclear facilities. It will be argued that public reactions to nuclear waste factilities must be seen in the context of more general attitudes toward nuclear energy. The latter are not only based upon perceptions of the health and environmental risks but are built on values, and sets of attributes which need not be similar to the representations o the experts and policy-makers. The issue of siting nuclear waste facilities is also embedded in a wider moral and political domain. This is illustrated by the importance of equity issues in siting radioactive wastes. In the last section, the implications of the present line of argument for risk communication and public participation in decisions about siting radioactive wastes will be briefly discussed.

    Astronomy deals with the position and observation of the objects in our Universe, from planets to galaxies. It is the oldest of the sciences. Astrophysics is the study of the physical properties of these objects. It dates from the start of the 20. century. Nuclear astrophysics is the marriage of nuclear physics, a laboratory science concerned with the infinitely small, and astrophysics, the science of what is far away and infinitely large. Its aim is to explain the origin, evolution and abundance of the elements in the Universe. It was born in 1938 with the work of Hans Bethe, an American physicist who won the Nobel Prize for physics in 1967, on the nuclear reactions that can occur at the center of stars. It explains where the incredible energy of the stars and the Sun comes from and enables us to understand how they are born, live and die. The matter all around us and from which we are made, is made up of ninety-two chemical elements that can be found in every corner of the Universe. Nuclear astrophysics explains the origin of these chemical elements by nucleosynthesis, which is the synthesis of atomic nuclei in different astrophysical environments such as stars. Nuclear astrophysics provides answers to fundamental questions: - Our Sun and the stars in general shine because nuclear reactions are taking place within them. - The stars follow a sequence of nuclear reaction cycles. Nucleosynthesis in the stars enables us to explain the origin and abundance of elements essential to life, such as carbon, oxygen, nitrogen and iron. - Star explosions, in the form of supernovae, disperse the nuclei formed by nucleosynthesis into space and explain the formation of the heaviest chemical elements such as gold, platinum and lead. Nuclear astrophysics is still a growing area of science. (authors)

Under these circumstances it is not difficult to show that on a more quantitative basis, the nuclear industry, in all countries, has an unblemished safety record when compared with other energy sources. Various hazards and benefits of nuclear power are analyzed in this paper comparing with other energy sources. (Liu)

    Nuclear astrophysics is that branch of astrophysics which helps understanding of the Universe, or at least some of its many faces, through the knowledge of the microcosm of the atomic nucleus. It attempts to find as many nuclear physics imprints as possible in the macrocosm, and to decipher what those messages are telling us about the varied constituent objects in the Universe at present and in the past. In the last decades much advance has been made in nuclear astrophysics thanks to the sometimes spectacular progress made in the modelling of the structure and evolution of the stars, in the quality and diversity of the astronomical observations, as well as in the experimental and theoretical understanding of the atomic nucleus and of its spontaneous or induced transformations. Developments in other subfields of physics and chemistry have also contributed to that advance. Notwithstanding the accomplishment, many long-standing problems remain to be solved, and the theoretical understanding of a large variety of observational facts needs to be put on safer grounds. In addition, new questions are continuously emerging, and new facts endangering old ideas. This review shows that astrophysics has been, and still is, highly demanding to nuclear physics in both its experimental and theoretical components. On top of the fact that large varieties of nuclei have to be dealt with, these nuclei are immersed in highly unusual environments which may have a significant impact on their static properties, the diversity of their transmutation modes, and on the probabilities of these modes. In order to have a chance of solving some of the problems nuclear astrophysics is facing, the astrophysicists and nuclear physicists are obviously bound to put their competence in common, and have sometimes to benefit from the help of other fields of physics, like particle physics, plasma physics or solid-state physics. Given the highly varied and complex aspects, we pick here some specific nuclear

    The Program on Nuclear Safety comprehends Radioprotection, Radioactive Waste Management and Nuclear Material Control. These activities are developed at the Nuclear Safety Directory. The Radioactive Waste Management Department (GRR) was formally created in 1983, to promote research and development, teaching and service activities in the field of radioactive waste. Its mission is to develop and employ technologies to manage safely the radioactive wastes generated at IPEN and at its customer’s facilities all over the country, in order to protect the health and the environment of today's and future generations. The Radioprotection Service (GRP) aims primarily to establish requirements for the protection of people, as workers, contractors, students, members of the general public and the environment from harmful effects of ionizing radiation. Furthermore, it also aims to establish the primary criteria for the safety of radiation sources at IPEN and planning and preparing for response to nuclear and radiological emergencies. The procedures about the management and the control of exposures to ionizing radiation are in compliance with national standards and international recommendations. Research related to the main activities is also performed. The Nuclear Material Control has been performed by the Safeguard Service team, which manages the accountability and the control of nuclear material at IPEN facilities and provides information related to these activities to ABACC and IAEA.

    It is expected that nuclear power generation will reach 49 million kW in 1985 and 129 million kW in 1995, and the nuclear fuel having to be supplied and processed will increase in proportion to these values. The technical problems concerning nuclear fuel are presented on the basis of the balance between the benefit for human beings and the burden on the human beings. Recently, especially the downstream of nuclear fuel attracts public attention. Enriched uranium as the raw material for light water reactor fuel is almost monopolized by the U.S., and the technical information has not been published for fear of the diversion to nuclear weapons. In this paper, the present situations of uranium enrichment, fuel fabrication, transportation, reprocessing and waste disposal and the future problems are described according to the path of nuclear fuel cycle. The demand and supply of enriched uranium in Japan will be balanced up to about 1988, but afterwards, the supply must rely upon the early establishment of the domestic technology by centrifugal separation method. No problem remains in the fabrication of light water reactor fuel, but for the fabrication of mixed oxide fuel, the mechanization of the production facility and labor saving are necessary. The solution of the capital risk for the construction of the second reprocessing plant is the main problem. Japan must develop waste disposal techniques with all-out efforts.

    This set of questions is based on an inquiry from the years 1987 to 1989. About 250 people af all age groups - primarily, however, young people between 16 and 25 years of age - were asked to state the questions they considered particularly important on the subject of nuclear energy. The survey was carried out without handicaps according to the brain-storming principle. Although the results cannot claim to be representative, they certainly reflect the areas of interest of many citizens and also their expectations, hopes and fears in connection with nuclear energy. The greater part of the questions were aimed at three topic areas: The security of nuclear power-stations, the effects of radioactivity on people and the problem of waste disposal. The book centres around these sets of questions. The introduction gives a general survey of the significance of nuclear energy as a whole. After this follow questions to do with the function of nuclear power stations, for the problems of security and waste disposal - which are dealt with in the following chapters - are easier to explain and to understand if a few physical and technical basics are understood. In the final section of the book there are questions on the so-called rejection debate and on the possibility of replacing nuclear energy with other energy forms. (orig./HP) [de

    In recent days, energy security is becoming a major global concern and it has been recognized that a major reduction in greenhouse-gas emissions is required to combat climate change. Considerable expansion and new introduction of nuclear power generation are currently being planned and considered for the further in various parts of the world. Nuclear technologies of the latest 10 years in Japan were reviewed with their characteristics, advancement and future perspective. Steady efforts have been made to construct new nuclear power stations with computer-aided engineering system and modular and prefabricated structures, extend the interval of periodic inspections under the new inspection system that should improve both safety and reliability, implement advanced measures against aging and develop the next-generation light water reactors including a medium small reactor. Export of nuclear power plants has been promoted with international business alliance or cooperation. Activities to close nuclear fuel cycle to ensure sustainable nuclear energy utilization have been promoted. Decommissioning technologies for Tokai power station have been developed and accumulated know-how will be utilized in light water reactors. (T. Tanaka)

    In 1979 the accident at Three Mile Island brought nuclear power to the forefront of national attention. Over the last five years there have been no new orders for nuclear plants, construction costs and lead times have increased drastically, and numerous plants have been cancelled. In the coming years many new plants will come on line, and the first round of nuclear plant retirements will begin. Thus, the new set of issues faced by utilities are whether to complete plants currently under construction, how to recover the cost of abandoned plants, how to handle the potential rate shock of bringing costly plants into rate base, and how to accomplish decommissioning and retirement of nuclear plants. This paper presents and analyzes these issues. First, the history of the nuclear electric generation industry is reviewed. Next a case study illustrating the cost momentum built into nuclear power plant construction is presented. The issues involved in plant cancellation are discussed. Finally, a case study involving rate phase-in strategies is analyzed. 1 reference, 7 figures

    The Koeberg nuclear power station, planned to come on stream in 1984, is expected to save South Africa some six million t/annum of coal, and to contribute some 10 per cent of the country's electricity requirements. The use of nuclear energy will provide for growing national energy needs, and reduce high coal transport costs for power generation at the coast. In the long term, however, it gives rise to the controversial question of nuclear waste storage. The Atomic Energy Corporation of South Africa Ltd (AEC) recently announced the purchase of a site in Namaqualand (NW Cape) for the storage of low-level radioactive waste. The Nuclear Development Corporation of South Africa (Pty) Ltd, (NUCOR) will develop and operate the site. The South African Mining and Engineering Journal interviewed Dr P.D. Toens, manager of the Geology Department and Mr P.E. Moore, project engineer, on the subject of nuclear waste, the reasons behind Nucor's choice of site and the storage method

    Levenson, M.

    1989-01-01

    The title of our session, Nuclear Risk Versus Other Power Options, is provocative. It is also a title with different meanings to different people. To the utility chief executive officer, nuclear power is a high-risk financial undertaking because of political and economic barriers to cost recovery. To the utility dispatcher, it is a high-risk future power source since plant completion and start-up dates can be delayed for very long times due to uncertain legal and political issues. To the environmentalist, concerned about global effects such as greenhouse and acid rain, nuclear power is a relatively low risk energy source. To the financial people, nuclear power is a cash cow turned sour because of uncertainties as to what new plants will cost and whether they will even be allowed to operate. The statistics on risk are known and the results of probability risk assessment calculations of risks are known. The challenge is not to make nuclear power safer, it is already one of the safest, if not the safest, source of power currently available. The challenge is to find a way to communicate this to the public

  17. Nuclear recession

    Speth, G.

    1978-01-01

    The private sector's growing doubts about nuclear power plants, as reflected in the decline in new orders and the number of rescinded orders, will result in an estimated total of under 300 nuclear power plants by the year 2000 rather than the 1200 to 1500 that were projected several years ago. The decline is a result of construction and equipment costs and a lower operating efficiency than anticipated. The growth of electricity demand also declined after 1974 and, although it is increasing again, there are concerns about future growth rates. Besides its noncompetitive position relative to coal, nuclear plant construction suffers from restrictive policies based on the uncertainties of safety, security, waste disposal, and proliferation. Unless these problems can be resolved, many consider nuclear power to be an impractical option as an energy source. The Council on Environmental Quality supports policies that will permit further nuclear or coal development only after a clear demonstration of technical and institutional capacity to handle these problems. A commitment to solar technology is urged

    Nuclear fusion can be relied on to solve the global energy crisis if the process of limiting the heat produced by the fusion reaction (Plasma) is successful. Currently scientists are progressively working on this aspect whereas there are two methods to limit the heat produced by fusion reaction, the two methods are auto-restriction using laser beam and magnetic restriction through the use of magnetic fields and research is carried out to improve these two methods. It is expected that at the end of this century the nuclear fusion energy will play a vital role in overcoming the global energy crisis and for these reasons, acquiring energy through the use of nuclear fusion reactors is one of the most urge nt demands of all mankind at this time. The conclusion given is that the source of fuel for energy production is readily available and inexpensive ( hydrogen atoms) and whole process is free of risks and hazards, especially to general health and the environment . Nuclear fusion importance lies in the fact that energy produced by the process is estimated to be about four to five times the energy produced by nuclear fission. (author)

    Friar, J.L.

    1998-01-01

    Nuclear scales are discussed from the nuclear physics viewpoint. The conventional nuclear potential is characterized as a black box that interpolates nucleon-nucleon (NN) data, while being constrained by the best possible theoretical input. The latter consists of the longer-range parts of the NN force (e.g., OPEP, TPEP, the π-γ force), which can be calculated using chiral perturbation theory and gauged using modern phase-shift analyses. The shorter-range parts of the force are effectively parameterized by moments of the interaction that are independent of the details of the force model, in analogy to chiral perturbation theory. Results of GFMC calculations in light nuclei are interpreted in terms of fundamental scales, which are in good agreement with expectations from chiral effective field theories. Problems with spin-orbit-type observables are noted

    In this paper the present status of the meson theory of nuclear forces is reviewed. After some introductory remarks about the relevance of the meson exchange concept in the era of QCD and the empirical features of the NN interaction, the exciting history of nuclear forces is briefly outlined. In the main part, the author gives the basic physical ideas and sketch the derivation of the one-boson-exchange model of the nuclear force, in the Feynman approach. Secondly we describe, in a qualitative way, various necessary extensions, leading to the Bonn model of the N interaction. Finally, points to some interesting pen questions connected with the extended quark structure of the hadrons, which are topics of current research activity

Investigations in the realms of particle and nuclear physicsmake a large contribution in the development of our ideas of the properties of the Universe. The present article discusses some problems of the evolution of the Universe, nucleosyntheses, and cosmochronology from the point of view of nuclear and particle physics. Processes occurring in the Universe are compared with the mechanisms of the production and decay of nuclei, as well as with the mechanisms of their interaction at high energies. Examples that demonstrate the potential of nuclearphysics methods for studying cosmic objects and the properties of the Universe are given. The results that come from investigations into nuclear reactions induced by beams of radioactive nuclei and which make it possible to take a fresh look at the nucleosynthesis scenario in the range at light nuclei are presented.

    Then-President Gerald Ford outlines the potential benefits of nuclear power as opposed to the danger of proliferation. He points out that not all nations have the same interest or views toward nuclear energy; but also he says that if a choice must be made, nonproliferation objectives must take precedence over economic and energy benefits. It is pointed out that the management of nuclear energy can be only partial and temporary by technical measures, and that full management can result only if nations realistically face the task prepared to forego preconceived short-term advantages in favor of long-term gains. Coordination of the policies of all nations toward the common goal of nonproliferation is predicted to lead to success

A lógica empresarial capitalista penetra em todos os segmentos produtivos, envolvendo tanto as indústrias que já operavam tradicionalmente nessas bases quanto segmentos que possuíam formas de organização em que era possível verificar a convivência de lógicas empresariais com outras que dela se afastavam, como a produção de vacinas e produtos biológicos, fitoderivados e a prestação de serviços de saúde. O artigo analisa a interação entre o sistema de saúde e o sistema econômico-industrial, mostrando como tem havido uma dicotomia na relação entre ambos, que se exprime na deterioração do potencial de inovação do país e numa crescente e preocupante vulnerabilidade externa da política de saúde. Sugere-se que o enfoque neoclássico tradicional da economia da saúde é insuficiente para tratar do complexo industrial da saúde, dada a intensidade do processo de mudança estrutural, e a necessidade de um enfoque teórico alternativo que incorpore a dinâmica de transformação econômica e institucional, de acumulação e de inovação.This article develops an analytical approach towards the study of health industrial complex, comprising the set of productive activities on health and their interdependencies, according to a perspective of political economics and innovation.

    Penn, J.

    Declaring nuclear preparedness 'immoral' helps to recreate the pacifism of 50 years ago. War itself is a dilemma, not the weapons with which it is waged. We must ask of the anti-war proposals: whom do they benefit. On the whole people concerned are ordinary citizens who are fearful of nuclear incineration. But marching with them is a spectrum of forces with other motivations and purposes. In a real life situation of international tension or crises, numbers of weapons in combination with their particular charateristics could mean the difference between peace and outbreak of war.

An almost incredible sequence of human and mechanical failures at this installation had stopped just short of disaster and had brought the unthinkable perilously close to happening. The accident had sprayed radioactive waste into the air and had led to the large scale evacuation of people from the endangered area, disrupted hundreds of thousands of lives and caused a crippling setback to the nuclear industry.

    The birth of nuclear cardiology has generally been attributed to a 1927 experiment during which a radium salt was injected in one arm vein and the circulation time calculated by recording the arrival of the radioactivity in the opposite arm. This simple experiment lead to the radiocardiogram in the late 1940s that was used to measure left ventricular function and, later, cardiac output. This chapter provides a brief overview of nuclear cardiology. Methodology is presented when it is important for the understanding of test results. The use of these studies in the diagnosis and evaluation of patients with suspected cardiovascular disease is emphasized

    This book originated in the training courses for teachers of grammar- and secondary schools in Dillingen (Bavaria). The aim of these courses is to become informed about the latest state in one field of physics. The lectures are well-known experts in the respective fields. In the latest study (1980) of the National Academy of Sciences the experts came to the conclusion that without further development nuclear power plants the utilization of too much coal would become necessary and involve irreversible environmental damage (see chapter 6). There are two important obstacles impeding the further extension of nuclear energy. The first problem to be solved is the processing and storage of radioactive waste. This is a more technical task and can be treated in a satisfactory way. The second obstacle is less easy to take as the population has to be convinced that a nuclear power plant can be operated with almost unbelievable safety (see chapter 5) and be shut down safely in the case of incidents. The most promising possibility of controlled nuclear fusion as energy source is still many decades- if feasible at all- away from being performed (see chapter. 7). In the Soviet Union 25% of the electric energy production shall be proceed from nuclear power plants by the year 1990. (orig./GL) [de

  20. Nuclear winter or nuclear fall?

    Science.gov (United States)

    Berger, André

    Climate is universal. If a major modern nuclear war (i.e., with a large number of small-yield weapons) were to happen, it is not even necessary to have a specific part of the world directly involved for there to be cause to worry about the consequences for its inhabitants and their future. Indeed, smoke from fires ignited by the nuclear explosions would be transported by winds all over the world, causing dark and cold. According to the first study, by Turco et al. [1983], air surface temperature over continental areas of the northern mid-latitudes (assumed to be the nuclear war theatre) would fall to winter levels even in summer (hence the term “nuclear winter”) and induce drastic climatic conditions for several months at least. The devastating effects of a nuclear war would thus last much longer than was assumed initially. Discussing to what extent these estimations of long-term impacts on climate are reliable is the purpose of this article.

    A nuclear reactor is described in which the core consists of a number of fuel regions through each of which regulated coolant flows. The coolant from neighbouring fuel regions is combined in a manner which results in an averaging of the coolant temperature at the outlet of the core. By this method the presence of hot streaks in the reactor is reduced. (UK)

    Nuclear reactions' marks a new development in the study of television as an agency of public policy debate. During the Eighties, nuclear energy became a major international issue. The disasters at Three-mile Island and Chernobyl created a global anxiety about its risks and a new sensitivity to it among politicians and journalists. This book is a case-study into documentary depictions of nuclear energy in television and video programmes and into the interpretations and responses of viewers drawn from many different occupational groupings. How are the complex and specialist arguments about benefit, risk and proof conveyed through the different conventions of commentary, interview and film sequence? What symbolic associations does the visual language of television bring to portrayals of the issue? And how do viewers make sense of various and conflicting accounts, connecting what they see and hear on the screen with their pre-existing knowledge, experience and 'civic' expectations. The authors examine some of the contrasting forms and themes which have been used by programme makers to explain and persuade, and then give a sustained analysis of the nature and sources of viewers' own accounts. 'Nuclear Reactions' inquires into the public meanings surrounding energy and the environment, spelling out in its conclusion some of the implications for future media treatments of this issue. It is also a key contribution to the international literature on 'television knowledge' and the processes of active viewing. (author)

  12. Nuclear waste

    International Nuclear Information System (INIS)

    1990-06-01

    DOE estimates that disposing of radioactive waste from civilian nuclear power plants and its defense-related nuclear facilities could eventually end up costing $32 billion. To pay for this, DOE collects fees from utilities on electricity generated by nuclear power plants and makes payments from its defense appropriation. This report states that unless careful attention is given to its financial condition, the nuclear waste program is susceptible to future shortfalls. Without a fee increase, the civilian-waste part of the program may already be underfunded by at least $2.4 billion (in discounted 1988 dollars). Also, DOE has not paid its share of cost-about $480 million-nor has it disclosed this liability in its financial records. Indexing the civilian fee to the inflation rate would address one major cost uncertainty. However, while DOE intends to do this at an appropriate time, it does not use a realistic rate of inflation as its most probable scenario in assessing whether that time has arrived

    The question 'Do we really need nuclear power' is tackled within the context of Christian beliefs. First, an estimate is made of the energy requirements in the future and whether it can be got in conventional ways. The dangers of all the ways of supplying energy (eg coal mining, oil and gas production) are considered scientifically. Also the cost of each source and its environmental effects are debated. The consequences of developing a new energy source, as well as the consequences of not developing it, are considered. Decisions must also take into account a belief about the ultimate purpose of life, the relation of men to each other and to nature. Each issue is raised and questions for discussion are posed. On the whole the book comes down in favour of nuclear power.

    Purpose: To improve the nuclear reactor availability by enabling to continuously exchange fuels in the natural-slightly enriched uranium region during operation. Constitution: A control rod is withdrawn to the midway of a highly enriched uranium region by means of control rod drives and the highly enriched uranium region is burnt to maintain the nuclear reactor always at a critical state. At the same time, fresh uranium-slightly enriched uranium is continuously supplied gravitationally from a fresh fuel reservoir through fuel reservoir to each of fuel pipes in the natural-slightly enriched uranium region. Then, spent fuels reduced with the reactivity by the burn up are successively taken out from the bottom of each of the fuel pipes through an exit duct and a solenoid valve to the inside of a spent fuel reservoir and the burn up in the natural-slightly enriched uranium region is conducted continuously.

    The Privacy Act of 1974 restricts both the type of information on private individuals that federal agencies may maintain in their records and the conditions under which such information may be disclosed. The Nuclear Regulatory Commission, which must approve DOE plans to build a nuclear waste repository at the Yucca Mountain site in Nevada, requires a quality assurance program to guarantee that studies of the site are done by qualified employees. Under such a program, the training and qualifications of DOE and contractor employees would be verified.

    Watson, C.

    2005-01-01

    This article is aimed at those professional scientists and engineers who believe that issues of international peace and security are too important to be left to the politicians. Nuclear Terrorism is a hostile act (or a threat of such an act) involving nuclear materials (fissile or radioactive) performed by a terrorist, a term which covers a wide range of individuals. What they all have in common is that, for some reason they have become motivated to hurt or destroy sections of society which they have come to regard as the enemy; their motivation varies enormously. They also vary enormously in the extent and nature of their technical/scientific education. There are 'PhD terrorists' and 'Peasant terrorists', and they differ greatly in the threat that they represent, and the steps which can appropriately be taken to counter it. The most serious threat comes from the potential ability of terrorists to steal or manufacture nuclear weapons of mass destruction (e.g. capable of causing thousands of deaths). Unless the underlying causes of terrorism can be quickly removed, we have a duty to mankind to make terrorist access to such weapons, and to the nuclear materials which are their essential ingredients, as difficult as possible. Improvements in the arrangements for denying unauthorised access to radioactive material should be made such that the protective measures made are proportionate to the number of Curies at risk and the likelihood of a terrorist initiative. The preventative measures, sadly, need to take account of the possibility that the terrorist will use lethal force to access the material. (author)

    Except for dedicated devices for mobile nuclear cardiology for instance, the market is set on variable angulation dual heads cameras. These cameras are suited for all general applications and their cost effectiveness is optimized. Now, all major companies have such a camera in their of products. But, the big question in nuclear medicine is about the future of coincidence imaging for the monitoring of treatments in oncology. Many companies are focused on WIP assessments to find out the right crustal thickness to perform both high energy FDG procedures and low energy Tc procedures, with the same SPECT camera. The classic thickness is 3/8''. Assessments are made with 1/2'', 5/8'' or 3/4'' crystals. If FDG procedures proved to be of great interest in oncology, it may lead to the design of a dedicated SPECT camera with a 1'' crustal. Due to the short half of FDG, it may be the dawning of slip ring technology. (e.g. Varicam from Elscint). The three small heads camera market seems to be depressed. Will the new three large heads camera unveiled by Picker, reverse that trend? The last important topic in nuclear medicine is the emergence of new flat digital detectors to get rid of the old bulky ones. Digirad is the first company to manufacture a commercial product based on that technology. Bichron, Siemens and General Electric are working on that development, too. But that technology is very expensive and the market for digital detection in nuclear medicine is not as large as the market in digital detection in radiology. (author)

    A portable, computerized nuclear probe designed to measure left ventricular function is described. The ejection fraction was reproducible and correlated well with that obtained by means of a gamma camera. The limitations of the machine are that it measures the global, rather than the segmental, function of the left ventricle and, when discrete large areas of regional dysfunction occur, the global ejection fraction may be overestimated. An advantage is that continuous beat-to-beat measurements are easily performed and displayed.

    Sufficient work has now been done, on a world-wide basis, to justify confidence that full decommissioning of nuclear installations, both plant and reactors, can be carried out safely and efficiently. Projects in several countries should confirm this in the next few years. In the UK, good progress has been made with the WAGR and supporting development work is finding solutions to resolve uncertainties. Estimates from several sources suggest that decommissioning costs can be kept to an acceptable level.

    1978-01-01

    2 1/2 years ago a consultation group was formed to help the Section for Social Questions of the Council of Churches in the Netherlands, to answer questions in the area of nuclear energy. During this time the character of the questions has changed considerably. In the beginning people spoke of fear and anxiety over the plans for the application of this new technical development but later this fear and anxiety turned to protest and opposition. This brochure has been produced to enlighten people and try and answer their alarm, by exploring the many facets of the problems. Some of these problems are already being deeply discussed by the public, others play no role in the forming of public opinion. The points of view of the churches over nuclear energy are not expressed, the brochure endeavours to express that nuclear energy problems are a concern for the churches. Technical and economic information and the most important social questions are discussed. (C.F.)

    James, A.E. Jr.; Squire, L.F.

    1977-01-01

    The book presents a number of fundamental imaging principles in nuclear medicine. The fact that low radiation doses are sufficient for the study of normal and changed physiological functions of the body is an important advancement brought about by nuclear medicine. The possibility of quantitative investigations of organs and organ regions and of an assessment of their function as compared to normal values is a fascinating new diagnostic dimension. The possibility of comparing the findings with other pathological findings and of course control in the same patient lead to a dynamic continuity with many research possibilities not even recognized until now. The limits of nuclear scanning methods are presented by the imprecise structural information of the images. When scintiscans are compared with X-ray images or contrast angiography, the great difference in the imaging of anatomical details is clearly seen. But although the present pictures are not optimal, they are a great improvement on the pictures that were considered clinically valuable a few years ago. (orig./AJ) [de

    1990-01-01

    This book fills a gap in current literature by covering the increasing nuclear physics content of various A-level syllabuses. In section 1 we outline the background and early development of the subject, in section 2 we deal with nuclear properties and theories at a level suitable for the pre-university student. The majority of topics have been treated with the limited use of mathematics, this necessitating some simplification which we hope to have accomplished without undue error. A few topics have been developed mathematically, to some extent, e.g. series decay. While it is the purpose of a book at this level to introduce the reader to the facts and theories of nuclear physics, we have to recognise that any teacher of science, at any level, must attempt to instill in the young scientist a sense of responsibility and an understanding of the problems attendant on the technological applications are important. These problems have been touched on in the text but we hope the student will be persuaded to read further; for this purpose we have added a short list of suggested additional reading. A selection of A-level past paper questions has been included. (author)

    During September and October 2001, 15 events were recorded on the first grade and 1 on the second grade of the INES scale. The second grade event is in fact a re-classification of an incident that occurred on the second april 2001 at Dampierre power plant. This event happened during core refueling, a shift in the operation sequence led to the wrong positioning of 113 assemblies. A preliminary study of this event shows that this wrong positioning could have led, in other circumstances, to the ignition of nuclear reactions. Even in that case, the analysis made by EDF shows that the consequences on the staff would have been limited. Nevertheless a further study has shown that the existing measuring instruments could not have detected the power increase announcing the beginning of the chain reaction. The investigation has shown that there were deficiencies in the control of the successive operations involved in refueling. EDF has proposed a series of corrective measures to be implemented in all nuclear power plants. The other 15 events are described in the article. During this period 121 inspections have been made in nuclear facilities. (A.C.)

  10. Nuclear fuels

    International Nuclear Information System (INIS)

    2008-01-01

    The nuclear fuel is one of the key component of a nuclear reactor. Inside it, the fission reactions of heavy atoms, uranium and plutonium, take place. It is located in the core of the reactor, but also in the core of the whole nuclear system. Its design and properties influence the behaviour, the efficiency and the safety of the reactor. Even if it represents a weak share of the generated electricity cost, its proper use represents an important economic stake. Important improvements remain to be made to increase its residence time inside the reactor, to supply more energy, and to improve its robustness. Beyond the economical and safety considerations, strategical questions have to find an answer, like the use of plutonium, the management of resources and the management of nuclear wastes and real technological challenges have to be taken up. This monograph summarizes the existing knowledge about the nuclear fuel, its behaviour inside the reactor, its limits of use, and its R and D tracks. It illustrates also the researches in progress and presents some key results obtained recently. Content: 1 - Introduction; 2 - The fuel of water-cooled reactors: aspect, fabrication, behaviour of UO 2 and MOX fuels inside the reactor, behaviour in loss of tightness situation, microscopic morphology of fuel ceramics and evolution under irradiation - migration and localisation of fission products in UOX and MOX matrices, modeling of fuels behaviour - modeling of defects and fission products in the UO 2 ceramics by ab initio calculations, cladding and assembly materials, pellet-cladding interaction, advanced UO 2 and MOX ceramics, mechanical behaviour of the fuel assembly, fuel during a loss of coolant accident, fuel during a reactivity accident, fuel during a serious accident, fuel management inside reactor cores, fuel cycle materials balance, long-term behaviour of the spent fuel, fuel of boiling water reactors; 3 - the fuel of liquid metal fast reactors: fast neutrons radiation

A history of political decisions on weapon development is given, along with a what if analysis of other options. The lesson of these two books is that it has proved considerably easier to live with nuclear weapons and the Soviet Union than anyone expected forty years ago. It is all the easier if arms control issues, based on worst case analyses, are kept in their place, which is firmly in the background of the overall conduct of foreign policy

    Today the applications of nuclear physics span a very broad range of topics and fields. This review discusses a number of aspects of these applications, including selected topics and concepts in nuclear reactor physics, nuclear fusion, nuclear non-proliferation, nuclear-geophysics, and nuclear medicine. The review begins with a historic summary of the early years in applied nuclear physics, with an emphasis on the huge developments that took place around the time of World War II, and that underlie the physics involved in designs of nuclear explosions, controlled nuclear energy, and nuclear fusion. The review then moves to focus on modern applications of these concepts, including the basic concepts and diagnostics developed for the forensics of nuclear explosions, the nuclear diagnostics at the National Ignition Facility, nuclear reactor safeguards, and the detection of nuclear material production and trafficking. The review also summarizes recent developments in nuclear geophysics and nuclear medicine. The nuclear geophysics areas discussed include geo-chronology, nuclear logging for industry, the Oklo reactor, and geo-neutrinos. The section on nuclear medicine summarizes the critical advances in nuclear imaging, including PET and SPECT imaging, targeted radionuclide therapy, and the nuclear physics of medical isotope production. Each subfield discussed requires a review article unto itself, which is not the intention of the current review; rather, the current review is intended for readers who wish to get a broad understanding of applied nuclear physics.

Ejection fractions (EF) obtained by this device showed a satisfactory correlation with values obtained by the cardiac pool multigate (MUGA) method using a scinticamera and minicomputer, with a slight tendency to overestimation. They showed a good correlation with left ventriculography, accompanied by a slight tendency to underestimation. The reproducibility of this device was also satisfactory. Clinically, EF values during exercise in ischemic heart disease were well correlated with those obtained by the MUGA method. This device permitted real time evaluation of left ventricular function and was highly reliable.

    1991-01-01

    Nuclei, like more familiar mechanical systems, undergo simple vibrational motion. Among these vibrations, sound modes are of particular interest since they reveal important information on the effective interactions among the constituents and, through extrapolation, on the bulk behaviour of nuclear and neutron matter. Sound wave propagation in nuclei shows strong quantum effects familiar from other quantum systems. Microscopic theory suggests that the restoring forces are caused by the complex structure of the many-Fermion wavefunction and, in some cases, have no classical analogue. The damping of the vibrational amplitude is strongly influenced by phase coherence among the particles participating in the motion. (author)

    Nuclear dualism is a characteristic feature of the ciliated protozoa. Tetrahymena have two different nuclei in each cell. The larger, polyploid, somatic macronucleus (MAC) is the site of transcriptional activity in the vegetatively growing cell. The smaller, diploid micronucleus (MIC) is transcriptionally inactive in vegetative cells, but is transcriptionally active in mating cells and responsible for the genetic continuity during sexual reproduction. Although the MICs and MACs develop from mitotic products of a common progenitor and reside in a common cytoplasm, they are different from one another in almost every respect.

    This paper discusses the Department of Energy's (DOE) procedures for annually assessing the adequacy of the fee that utilities pay for disposal of spent (used) nuclear fuel. In a June 1990 report, it was recommended, among other things, that the Congress authorize DOE to automatically adjust the fee each year on the basis of an inflation index. At that time, DOE also favored fee indexing; however, it subsequently reversed its position. Because of this change, it is now believe that Congress should require DOE to index the fee to the rate of inflation

The guide rods also extend back into the fuel assembly such that they are relatively rigid members. The guide rods are tied to the fuel assembly end or support plates and serve as structural members which are supported independently of the fuel element. Fuel element spacing and support means may be attached to the guide rods. 9 claims

Ninety-one family members were interviewed, 47 from the public hospital and 44 from the private one, using the Brazilian adaptation of the Critical Care Family Need Inventory (INEFTI. There was no significant difference between the groups in the total score of importance attributed to the needs (p=0.410. The satisfaction score was higher in the private hospital than in the public one (p=0.002. Multiple linear regression analysis allowed us to establish a hierarchy of importance and satisfaction of the family members' needs in each group. The differences observed between the groups suggest that the fulfillment of their needs requires interventions directed at the specificity of each type of hospital.Se trata de un estudio transversal, con objeto de analizar y comparar las necesidades de los familiares de pacientes adultos internados en UTIs de un hospital público y un privado, respecto al grado de importancia y satisfacción.

    This thesis deals with two topics in nuclear cardiology. In the first, left ventricular wall motion assessment using Fourier transform of local left ventricular time-activity curves in gated blood pool studies is evaluated. In the second, the interpretation of myocardial perfusion scintigrams is assessed which are obtained with thallium-201 or with another radiopharmaceutical with different physical, but identical biological properties. In all these investigations data acquisition and analysis by computer played an essential role. In chapter 1 the desirable properties of a nuclear medicine computer system are given and the computer system used for this work is described. Wall motion analysis of the left ventricle using Fourier transform of local time-activity curves in the left ventricular region in gated blood pool studies is described in chapter 2. In chapter 3 detection of non-perfused lesions in myocardial perfusion scintigraphy with thallium-201 is described. Detection of partly perfused lesions and the influence of scatter and photon energy on myocardial perfusion scintigraphy is described in chapter 4. (Auth.)

    Reference is made to auxiliary means of cooling the nuclear fuel clusters used in light or heavy water cooled nuclear reactors. One method is to provide one or more spray cooling tubes. From holes in the side walls of those tubes coolant water may be sprayed laterally into the cluster against the rods. The flow of main coolant may thus be supplemented or even replaced by the auxiliary coolant. A difficulty, however, is that only those fuel rods close to a spray cooling tube can readily be reached by the auxiliary coolant. In the arrangement described, where the fuel rods are spaced apart by transverse grids, at least one of the interspaces between the grids is provided with an axially extending auxiliary coolant conduit having lateral holes through which an auxiliary coolant is sprayed into the cluster. A deflector is provided that extends from a transverse grid into a position in front of the holes and deflects auxiliary coolant on to parts of the fuel rods otherwise inaccessible to the auxiliary coolant. The construction of the deflector is described. (U.K.)

    A nuclear reactor has an upper and a lower grid plate. Protrusions project from the upper grid plate. Fuel assemblies having end fittings fit between the grid plates. An arrangement is provided for accepting axial forces generated during the operation of the nuclear reactor by the flow of the cooling medium and thermal expansion and irradiation-induced growth of the fuel assembly, which comprises rods. Each fuel assembly rests on the lower grid plate and its upper end is elastically supported against the upper grid plate by the above-mentioned arrangement. The arrangement comprises four (for example) torsion springs each having a torsion tube and a torsion bar nested within the torsion tube and connected at one end thereto. The other end of the torsion bar is connected to an associated one of four lever arms. The torsion tube is rigidly connected to the other end fitting and the springs are disposed such that the lever arms are biassed against the protrusions. (author)

    In a strange turn of history, the threat of global nuclear war has gone down, but the risk of a nuclear attack has gone up. The danger of nuclear terrorism and ways to thwart it, tackle it and manage it in the event of an attack is increasingly gaining the attention of nuclear analysts all over the world. There is rising awareness among nuclear experts to develop mechanisms to prevent, deter and deal with the threat of nuclear terrorism. Nuclear specialists are seeking to develop and improve the science of nuclear forensics so as to provide faster analysis during a crisis. Nuclear forensics can play an important role in detecting illicit nuclear materials to counter trafficking in nuclear and radiological materials. An effective nuclear forensic and attribution strategy can enable policy makers, decision makers and technical managers to respond to situations involving interception of special nuclear materials

    Full Text Available Nuclear weapons have played an important role in China's national strategy. China’s nuclear doctrine has a very strong continuity. Nevertheless, China has made readjustments in its nuclear doctrine according to the changes of its internal and external situation and its general strategic threat perception. China’s nuclear doctrine has experienced a process of evolution from anti-nuclear blackmail to minimum deterrence. There are five major parts in China's nuclear doctrine: policy of declaration, nuclear development, nuclear deployment, nuclear employment, and nuclear disarmament. Because China is faced with a different situation from other nuclear powers and has its own strategic culture, China has a nuclear doctrine with its own characteristics. China’s nuclear doctrine has been affiliated with and has served the national development strategy, national security strategy, national defense policy and military strategy of China.

    The Sizewell 'B' Nuclear Power Station, the first in a new family of PWR (Pressurised Water Reactor) stations in the UK, is currently under construction on the Suffolk coast. One of the first civil engineering tasks associated with the power station construction was the necessity to lower the water table by 17-18 m over an area of approximately 8 hectares to allow the excavation for the foundations to be carried out in the dry. The way chosen to do this was to construct a diaphragm wall around the site area. This had the least effect on surrounding sites -the Sizewell-A station and various nature reserves and wetlands. The reasons for the choice of method are discussed. Following the construction of the wall the water was pumped out from within the diaphragm wall in January 1988. (author)

    It is shown that there are at least four instances known of reasonably accurate forecasts of the benefits and dangers of nuclear energy. H.G. Wells' atomic bomb of 1914, A.W. Stewart's chain reaction of 1923, Olaf Stapeldon's mushroom cloud of 1930 and Hans Dominik's tactical atomic weapon of 1927 are briefly reviewed as well as a forecast of the Three Mile island accident. These examples show that although the trained imagination of writers can approach the truth none can claim accuracy in predicting the facts. Where they do approach the truth is in the prediction of the consequences of the discoveries, social as well as military, of unlimited energy and of unlimited disasters. (U.K.)

    The Department of Energy is awarding grants to the state of Nevada for the state's participation in DOE's program to investigate Yucca Mountain as a possible site for the disposal of civilian nuclear waste. This report has found that DOE's financial assistance budget request of $15 million for Nevada's fiscal year 1990 was not based on the amount the state requested but rather was derived by increasing Nevada's grant funds from the previous year in proportion to the increase that DOE requested for its own activities at the Nevada site. DOE's evaluations of Nevada's requests are performed too late to be used in DOE's budget formulation process because Nevada has been applying for financial assistance at about the same time that DOE submits its budget request to Congress

    This paper reviews the Department of Energy's management of underground single-shell waste storage tanks at its Hanford, Washington, site. The tanks contain highly radioactive and nonradioactive hazardous liquid and solid wastes from nuclear materials production. Hundreds of thousands of gallons of these wastes have leaked, contaminating the soil, and a small amount of leaked waste has reached the groundwater. DOE does not collect sufficient data to adequately trace the migration of the leaks through the soil, and studies predicting the eventual environmental impact of tank leaks do not provide convincing support for DOE's conclusion that the impact will be low or nonexistent. DOE can do more to minimize the environmental risks associated with leaks. To reduce the environmental impact of past leaks, DOE may be able to install better ground covering over the tanks to reduce the volume of precipitation that drains through the soil and carries contaminants toward groundwater

    Purpose: To facilitate and accelerate a leakage test of valves of a main steam pipe by adding a leakage test partition valve thereto. Constitution: A leakage testing partition valve is provided between a pressure vessel for a nuclear reactor and the most upstream side valve of a plurality of valves to be tested for leakage, a testing branch pipe is communicated with the downstream side of the partition valve, and the testing water for preventing leakage is introduced thereto through the branch pipe. Since main steam pipe can be simply isolated by closing the partition valve in the leakage test, the leakage test can be conducted without raising or lowering the water level in the pressure vessel, and since interference with other work in the reactor can be eliminated, the leakage test can be readily conducted parallel with other work in the reactor in a short time. Clean water can be used without using reactor water as the test water. (Yoshihara, H.)

    The invention concerns the use of burnable poisons in a nuclear reactor, especially in PWRs, in order to improve the controllability of the reactor. An unsymmetrical arrangement in the lattice is provided, if necessary also by insertion of special rods for these additions. It is proposed to arrange the burnable poisons in fuel elements taken over from a previous burn-up cycle and to distribute them, going out from the side facing the control rods, over not more than 20% of the lenth of the fuel elements. It seems sufficient, for the burnable poisons to bind an initial reactivity of only 0.1% and to become ineffective after normal operation of 3 to 4 months. (ORU) [de

    As required by the Nuclear Waste Policy Act of 1982, the Department of Energy is to annually determine whether the waste disposal fee will produce sufficient revenues to offset the total estimated costs of the waste disposal program. In its June 1987 assessment, DOE recommended that the fee remain unchanged even though its analysis showed that at an inflation rate of 4 percent the current fee would result in end-of-program deficits ranging from $21 billion to $76 billion in 2085. The 1988 assessment calls for reduced total costs because of program changes. Thus, DOE may be able to begin using a realistic inflation rate in determining fee adequacy in 1988 without proposing a major fee increase

    Each year, nuclear power plants, businesses, hospitals, and universities generate more than 1 million cubic feet of hardware, rags, paper, liquid waste, and protective clothing that have been contaminated with radioactivity. While most of this waste has been disposed of in facilities in Nevada, South Carolina, and Washington state, recent legislation made the states responsible - either individually, or through groups of states called compacts - for developing new disposal facilities. This paper discusses the states' progress and problems in meeting facility development milestones in the law, federal and state efforts to resolve issues related to mixed waste (low-level waste that also contains hazardous chemicals) and waste with very low levels of radioactivity, and the Department of Energy's progress in discharging the federal government's responsibility under the law to manage the most hazardous low-level waste

The reinsurance capacity of the other pools included, the total amount covered now amounts to 2 billion marks in property incurance and 200 million marks in liability incurance. As in the year before the pool can reckon with a stable gross premium yield around 175 million marks. The revival of the US dollar has played a decisive role in this development. In 1993 in the domestic market, the DKVG offered policies for 22 types of property risk and 43 types to third-party risk, operating with a gross target premium of 65 million marks and 16 million marks, respectively. The DKVG also participated in 540 foreign insurance contracts. (orig./HSCH) [de

    Fuel is one of the essential components in a reactor. It is within that fuel that nuclear reactions take place, i.e. fission of heavy atoms, uranium and plutonium. Fuel is at the core of the reactor, but equally at the core of the nuclear system as a whole. Fuel design and properties influence reactor behavior, performance, and safety. Even though it only accounts for a small part of the cost per kilowatt-hour of power provided by current nuclear power plants, good utilization of fuel is a major economic issue. Major advances have yet to be achieved, to ensure longer in-reactor dwell-time, thus enabling fuel to yield more energy; and improve ruggedness. Aside from economics, and safety, such strategic issues as use of plutonium, conservation of resources, and nuclear waste management have to be addressed, and true technological challenges arise.

  1. Nuclear experts and nuclear weapons proliferation

    International Nuclear Information System (INIS)

    Mueller, H.

    1979-01-01

    In Germany the issue of nuclear weapons proliferation has attracted scant attention. Most potential nuclear weapon states are important trade partners of the FRG and, since further proliferation of nuclear weapons could worsen conflicts involving these, it should be in the FRG's interest to limit proliferation. The security of the FRG is also dependent on the common interest of the great powers to avoid nuclear war. The contradictory positions of Usa and the USSR on nuclear weapons policy regarding themselves and non-nuclear weapon states encourages less developed countries to see nuclear weaponry as useful. The NPT and IAEA safeguards have only limited inhibiting effect. The nuclear export policy of the FRG has been dominated by short term economic advantage, neglecting the negative long term effects of decreased political stability. The FRG should formulate a policy based on self-restraint, positive stimuli and extension of controls, using its economic strength to deter proliferation. (JIW)

    The objective of safeguards is the timely detection of diversion of significant quantities of nuclear material from peaceful nuclear activities to the manufacture of nuclear weapons or of other nuclear explosive devices or for purposes unknown, and deterrence of such diversion by the risk of early detection. The safeguards system should be designed to provide credible assurances that there has been no diversion of declared nuclear material and no undeclared nuclear material and activities.

    International Nuclear Information System (INIS)

    Miraillet, Michel

    2010-01-01

    Within an unstable international environment and an unpredictable future, nuclear weapons will continue to play a major role in defense policies. Indeed, since disarmament currently seems an unlikely objective, nuclear weapons remain as a security guarantee. Within this context, talk of the global abolition of nuclear weapons remains essentially rhetorical and the supposed link between disarmament and non-proliferation is a tenuous one. The foremost purpose of both disarmament and nuclear deterrence must be security

  13. Nuclear weapons modernizations

    Energy Technology Data Exchange (ETDEWEB)

    Kristensen, Hans M. [Federation of American Scientists, Washington, DC (United States)

    2014-05-09

    This article reviews the nuclear weapons modernization programs underway in the world's nine nuclear weapons states. It concludes that despite significant reductions in overall weapons inventories since the end of the Cold War, the pace of reductions is slowing - four of the nuclear weapons states are even increasing their arsenals, and all the nuclear weapons states are busy modernizing their remaining arsenals in what appears to be a dynamic and counterproductive nuclear competition. The author questions whether perpetual modernization combined with no specific plan for the elimination of nuclear weapons is consistent with the nuclear Non-Proliferation Treaty and concludes that new limits on nuclear modernizations are needed.

    International Nuclear Information System (INIS)

    Eriksen, V.O.

    1990-01-01

    The increasing number of accidents with nuclear submarines is a worriment to the general public. Five nuclear submarines are resting on the bottom of the North Atlantic. Design information on nuclear propulsion plants for submarines is classified. The author describes a potential generic nuclear submarine propulsion plant. Design information from the civilian nuclear industry, nuclear power plants, research reactors, nuclear cargo vessels and nuclear propelled icebreakers are used for illustration of relevant problems. A survey is given of nuclear submarines. Factors influencing the accident risks and safety characteristics of nuclear submarines are considered, and potential accident scenarios are described. The fission product content of the nuclear plant can be estimated, '' source terms'' can be guessed and potential release rates can be judged. The mechanisms of dispersion in the oceans is reviewed and compared with the dumping of radioactive waste in the Atlantic and other known releases. 46 refs., 49 figs., 14 tabs

  18. Nuclear knowledge management

    International Nuclear Information System (INIS)

    2007-01-01

    The management of nuclear knowledge has emerged as a growing challenge in recent years. The need to preserve and transfer nuclear knowledge is compounded by recent trends such as ageing of the nuclear workforce, declining student numbers in nuclear-related fields, and the threat of losing accumulated nuclear knowledge. Addressing these challenges, the IAEA promotes a 'knowledge management culture' through: - Providing guidance for policy formulation and implementation of nuclear knowledge management; - Strengthening the contribution of nuclear knowledge in solving development problems, based on needs and priorities of Member States; - Pooling, analysing and sharing nuclear information to facilitate knowledge creation and its utilization; - Implementing effective knowledge management systems; - Preserving and maintaining nuclear knowledge; - Securing sustainable human resources for the nuclear sector; and - Enhancing nuclear education and training

  20. Nuclear regulation

    International Nuclear Information System (INIS)

    1990-04-01

    Because of an accidental release in 1986 of low-level waste stored at the Wright-Patterson Air Force Base, Ohio, several individuals inhaled small amounts of a radioactive substance. GAO examined the Nuclear Regulatory Commission's oversight of the Department of Defense's use, handling, and disposal of radioactive material and found that no comprehensive DOD waste disposal program exists and none of the three services knows the full extent of its low-level radioactive waste disposal problems. Throughout the 1980s, the Army and the Air Force had, on occasion, been banned from disposal sites for failing to comply with federal and state requirements. By December 1992, two of the three sites now used by DOD to disposed of waste will close, and only a limited number of new sites may be available for several years. In the interim, DID will pay substantial surcharges to dispose of waste. After January 1993, DOD will have to comply with disposal requirements for as many as 16 sites or store waste on-site pending the availability of new sites. This report discusses how GAO believes DOD needs to take full advantage of the time between now and January 1993 to establish a low-level radioactive waste disposal program. DOD also needs to work with other federal agencies, compacts, and states to determine the feasibility of dedicating a portion of one or more disposal sites for the government's use

  1. Nuclear fusion

    International Nuclear Information System (INIS)

    Huber, H.

    1978-01-01

    A comprehensive survey is presented of the present state of knowledge in nuclear fusion research. In the first part, potential thermonuclear reactions, basic energy balances of the plasma (Lawson criterion), and the main criteria to be observed in the selection of appropriate thermonuclear reactions are dealt with. This is followed by a discussion of the problems encountered in plasma physics (plasma confinement and heating, transport processes, plasma impurities, plasma instabilities and plasma diagnostics) and by a consideration of the materials problems involved, such as material of the first wall, fuel inlet and outlet, magnetic field generation, as well as repair work and in-service inspections. Two main methods have been developed to tackle these problems: reactor concepts using the magnetic pinch (stellarator, Tokamak, High-Beta reactors, mirror machines) on the one hand, and the other concept using the inertial confinement (laser fusion reactor). These two approaches and their specific problems as well as past, present and future fusion experiments are treated in detail. The last part of the work is devoted to safety and environmental aspects of the potential thermonuclear aspects of the potential thermonuclear reactor, discussing such problems as fusion-specific hazards, normal operation and potential hazards, reactor incidents, environmental pollution by thermal effluents, radiological pollution, radioactive wastes and their disposal, and siting problems.

  2. Nuclear security

    International Nuclear Information System (INIS)

    1991-12-01

    This paper reports that despite their crucial importance to national security, safeguards at the Department of Energy's (DOE) weapons facilities may be falling short. DOE security inspections have identified many weaknesses, including poor performance by members of DOE's security force, poor accountability for quantities of nuclear materials, and the inability of personnel to locate documents containing classified information. About 13 percent of the 2,100 identified weakness resulted in DOE inspectors giving out unsatisfactory security ratings; another 38 percent led to marginal ratings. In addition, DOE's centralized safeguards and security information tracking system lacks current data on whether DOE field offices have corrected the identified weaknesses. Without reliable information, DOE has no way of knowing whether timely action was taken to correct problems, nor can it determine whether weaknesses are systematic. DOE has tried to minimize the impact of these security weaknesses at its facilities by establishing multiple layers of protection measures and instituting interim and compensatory measures for identified weaknesses. DOE is planning enhancements to the centralized tracking system that should improve its reliability and increase its effectiveness

  3. Nuclear reactors

    International Nuclear Information System (INIS)

    Prescott, R.F.; George, B.V.; Baglin, C.J.

    1979-01-01

    In a nuclear reactor (e.g. one having coolant down-flow through a core to a hearth below) thermal insulation (e.g. of a floor of the hearth) comprises a layer of bricks and a layer of tiles thereon, with smaller clearances between the tiles than between the bricks but with the bricks being of reduced cross-section immediately adjacent the tiles so as to be surrounded by interconnected passages, of relatively large dimensions, constituting a continuous chamber extending behind the layer of tiles. By this arrangement, lateral coolant flow in the inter-brick clearances is much reduced. The reactor core is preferably formed of hexagonal columns, supported on diamond-shaped plates each supported on a pillar resting on one of the hearth-floor tiles. Each plate has an internal duct, four upper channels connecting the duct with coolant ducts in four core columns supported by the plate, and lower channels connecting the duct to a downwardly-open recess common to three plates, grouped to form a hexagon, at their mutually-adjacent corners. This provides mixing, and temperature-averaging, of coolant from twelve columns

  4. Nuclear standards

    International Nuclear Information System (INIS)

    Fichtner, N.; Becker, K.; Bashir, M.

    1981-01-01

    This compilation of all nuclear standards available to the authors by mid 1980 represents the third, carefully revised edition of a catalogue which was first published in 1975 as EUR 5362. In this third edition several changes have been made. The title has been condensed. The information has again been carefully up-dated, covering all changes regarding status, withdrawal of old standards, new projects, amendments, revisions, splitting of standards into several parts, combination of several standards into one, etc., as available to the authors by mid 1980. The speed with which information travels varies and requires in many cases rather tedious and cumbersome inquiries. Also, the classification scheme has been revised with the goal of better adjustment to changing situations and priorities. Whenever it turned out to be difficult to attribute a standard to a single subject category, multiple listings in all relevant categories have been made. As in previous editions, within the subcategories the standards are arranged by organization (in Categorie 2.1 by country) alphabetically and in ascending numerical order. It covers all relevant areas of power reactors, the fuel cycle, radiation protection, etc., from the basic laws and governmental regulations, regulatory guides, etc., all the way to voluntary industrial standards and codes of pratice.

  5. Nuclear stethoscope

    International Nuclear Information System (INIS)

    1976-01-01

    A built-up image illustrating heart activity within the cardiac cycle is produced by simultaneously displaying a plurality of memory channels which accumulate respectively the amount of radioactivity detected within a cardiac chamber during successive intervals throughout the cardiac cycle. The parallel lines of a raster scan display correspond respectively to the memory channels. The count stored in a particular memory channel causes the video signal for the corresponding line to be maintained at a binary level for a corresponding time interval thus generating a bar graph in which the length of each bar indicates the amount of radioactivity sensed during the corresponding interval of the cardiac cycle. As each memory channel accumulates radioactivity data with each successive cardiac cycle, each bar displayed in the bar graph lengthens to indicate the cumulative activity until an interpretable curve is obtained. The invention relates generally to the field of nuclear medicine and, more specifically, to diagnostic techniques of analyzing blood flow through the heart by detecting radioactivity from radioisotopes injected into the bloodstream

    Purpose: To obtain an optimum structural arrangement of IRM having a satisfactory responsibility to the inoperable state of a nuclear reactor and capable of detecting the reactor power in an averaged manner. Constitution: As the structural arrangement of IRM, from 6 to 16 even number of IRM are bisected into equial number so as to belong two trip systems respectively, in which all of the detectors are arranged at an equal pitch along a circumference of a circle with a radius rl having the center at the position of the central control rod in one trip system, while one detector is disposed near the central control rod and other detectors are arranged substantially at an equal pitch along the circumference of a circle with a radius r2 having the center at the position for the central control rod in another trip system. Furthermore, the radius r1 and r2 are set such that r1 = 0.3 R, r2 = 0.5 R in the case where there are 6 IRM and r1 = 0.4 R and R2 = 0.8 R where there are eight IRM where R represents the radius of the reactor core.

    Price, D.C.

    1989-01-01

    The spleen is a sinusoidal vascular filter that is an integral part of the reticuloendothelial system and is the largest single lymphoid organ in the body. Thus it has important scavenging and immunologic functions in humans. It is also a site for normal hematopoiesis in humans during the third to sixth months of gestation. Solenic hematopoiesis does occur normally in adult animals of other species (for instance, mouse, rat, rabbit), but it is seen postnatally in humans only when they have certain hematologic disorders such as myelofibrosis with myeloid metaplasia and severe hemolytic anemias. In its role as a reticuloendothelial organ the adult human spleen serves as a vascular scavenger. Arterial blood filters through a network of arterioles, cords, and sinuses in a closed system that requires the blood cells to be pliable and brings them into intimate contact with macrophages suspended on the reticulin stroma of the cords. Erythrocyte culling and pitting functions as described by Crosby result in a transient retention of immature circulating erythroid cells until residual intracellular nuclear fragments have been extruded. The increased risk for overwhelming infection in children and adults whose spleen have been removed for reasons other than acute trauma would appear to be caused by the loss of both its phagocytic and its immunologic (antibody-producing) contributions to the monitoring of the circulating blood. This paper reports that the ability of the spleen to phagocytose intravascular foreign particles and to recognize and destroy damaged erythrocytes is the basis for the current use of radiopharmaceuticals in spleen scintigraphy

  9. Nuclear decisions

    International Nuclear Information System (INIS)

    Fischhoff, B.

    1991-01-01

    This attempts to identify the role of judgmental processes in various nuclear arms/war decisions. That task analysis is done with some confidence. The next two steps, diagnosing potential weaknesses in those judgments and suggesting ameliorative procedures, are done with increasing timidity. The empirical research base is not (ever) as large as one would like. It is particularly weak with regard to studies of experts forced to go beyond hard data and rely on intuitive judgments within their field of expertise. further evidence is needed to substantiate the claim that experts think like everyone else unless they have had the opportunity to master a particular kind of judgment as a learned skill. Although there is both theoretical and empirical reason to believe that various forms of decision aiding are possible, the high stakes involved mandate caution before proposing any intervention. Ineffective steps may make matters worse if they raise confidence without improving performance, or if they disrupt the cognitive ecology within which decision makers are accustomed to functioning, so that they lose touch with their own imperfect intuitions without acquiring viable alternatives

  10. Nuclear waste

    International Nuclear Information System (INIS)

    1990-07-01

    The state of Nevada opposed DOE's development of a nuclear waste repository at Yucca Mountain. As a result, disputes have arisen over how Nevada has spent financial assistance provided by DOE to pay the state's repository program costs. This report reviews Nevada's use of about $32 million in grant funds provided by DOE through June 1989 and found that Nevada improperly spent about $1 million. Nevada used as much as $683,000 for lobbying and litigation expenses that were unauthorized or were expressly prohibited by law, court decision, or grant terms; exceeded a legislative spending limit on socioeconomic studies by about $96,000; and used, contrary to grant terms, about $275,000 from one grant period to pay expenses incurred in the prior year. Also, Nevada did not always exercise adequate internal controls over grant funds, such as timely liquidation of funds advanced to contractors. A permissive approach to grant administration by DOE contributed to Nevada's inappropriate use of grant funds

    1975-01-01

    The energy crisis, high fuel costs and slow progress in the development of alternative energy sources, e.g. solar energy have given further impetus to nuclear power generation. The Swiss nuclear energy programme is discussed and details are given of nuclear station in operation, under construction, in the project stage and of Swiss participation in foreign nuclear stations. Reference is made to the difficulties, delays and resulting cost increases caused by local and regional opposition to nuclear power stations. The significant contributions made by Swiss industry and Swiss consulting engineers are discussed. (P.G.R.)

  12. Nuclear disarmament and peaceful nuclear technology

    International Nuclear Information System (INIS)

    Taylor, T.B.

    1989-01-01

    According to the author, it remains to be seen whether nuclear disarmament can reduce the risks of nuclear war sufficiently for the residual risks to be acceptable to a majority of the world's population, while at the same time vigorous growth in the world's dependence on nuclear energy for peaceful purposes continues. This paper discusses how use of nuclear materials from dismantled weapons as fuel for peaceful purposes may help progress to be made towards that goal, by stimulating considerable improvements in the effectiveness of arrangements for preventing diversion of the materials from peaceful to military purposes, while at the same time eliminating large numbers of nuclear weapons

    2000-01-01

    Nuclear power is an important and, the authors believe, essential component of a secure nuclear future. Although nuclear fuel cycles create materials that have some potential for use in nuclear weapons, with appropriate fuel cycles, nuclear power could reduce rather than increase real proliferation risk worldwide. Future fuel cycles could be designed to avoid plutonium production, generate minimal amounts of plutonium in proliferation-resistant amounts or configurations, and/or transparently and efficiently consume plutonium already created. Furthermore, a strong and viable US nuclear infrastructure, of which nuclear power is a large element, is essential if the US is to maintain a leadership or even participatory role in defining the global nuclear infrastructure and controlling the proliferation of nuclear weapons. By focusing on new fuel cycles and new reactor technologies, it is possible to advantageously burn and reduce nuclear materials that could be used for nuclear weapons rather than increase and/or dispose of these materials. Thus, the authors suggest that planners for a secure nuclear future use technology to design an ideal future. In this future, nuclear power creates large amounts of virtually atmospherically clean energy while significantly lowering the threat of proliferation through the thoughtful use, physical security, and agreed-upon transparency of nuclear materials. The authors must develop options for policy makers that bring them as close as practical to this ideal. Just as Atoms for Peace became the ideal for the first nuclear century, they see a potential nuclear future that contributes significantly to power for peace and prosperity

  9. Security with nuclear weapons

    International Nuclear Information System (INIS)

    Karp, R.C.

    1991-01-01

    Recent improvements in East-West relations and the process of dramatic political change in Europe may result in unprecedented opportunities to reduce the global arsenal of nuclear weapons. Despite these welcome developments, the prospects for effectively controlling the spread of nuclear capability in the Third World have remained much less encouraging. The possibility of large reductions in nuclear weapons poses fundamental questions about their purpose. Why have some states chosen to acquire nuclear weapons? How and why have these decisions been maintained over time? Why have some states elected to approach, but not cross, the nuclear threshold? This book examines the commonalities and differences in political approaches to nuclear weapons both within and between three groups of states: nuclear, non-nuclear and threshold. The chapters explore the evolution of thinking about nuclear weapons and the role these weapons play in national security planning, and question the official security rationales offered by the nuclear weapon states for the maintenance of nuclear capabilities. For the non-nuclear weapon states, the book presents an analysis of alternative ways of assuring security and foreign policy effectiveness. For the threshold states, it examines the regional contexts within which these states maintain their threshold status. This book transcends traditional East-West approaches to analysis of nuclear issues by giving equal prominence to the issues of nuclear proliferation and non-nuclearism. The book also provides a comprehensive analysis of how current approaches to nuclear weapons have evolved both within and among the groups of countries under study

    Although United States Customs recently prevented 40 krytrons, fast triggers to start a nuclear fission detonation, from being exported, other countries have been able to acquire similar items without questions being asked. Nuclear power plants have been exported to Pakistan and it is expected that this will enable Pakistan to become the world's ninth nuclear weapons state. Not all current or potential nuclear weapons states have signed and ratified the Non-Proliferation Treaty. Some nuclear plant have been built in developing countries without proper International Atomic Energy Authority Control. It would seem that there is a general indifference to nuclear proliferation by some of the western nuclear countries. (UK)
