    Full Text Available Resumo: Dentre os princípios do SUS, o de integralidade talvez seja o mais desafiador na construção da Reforma Sanitária. É objetivo deste estudo identificar momentos críticos do debate conceitual em torno da integralidade e suas contribuições para a reflexão acerca de tecnologias de atenção à saúde no âmbito do SUS. O ensaio percorre algumas construções conceituais que se aproximam da questão da integralidade como princípio norteador de programas e ações de saúde em diversos planos e dimensões da organização da atenção à saúde - das interações intersubjetivas à organização de redes regionais. O estudo se baseou em revisão não sistemática da literatura sobre o tema da integralidade e afins na produção do campo da Saúde Coletiva brasileira nas últimas cinco décadas. Propõe-se uma cronologia/tipologia que se estende dos anos 1960 à década de 2010, dividindo-a em quatro períodos/categorias julgados significativos. A narrativa não pretende ser exaustiva, mas construir uma referência compreensiva capaz de contribuir para análises, avaliações e debates acerca da organização da atenção à saúde no SUS conforme o princípio da integralidade.

    2011-10-01

    Full Text Available O objetivo deste estudo é debater o discurso das enfermeiras sobre o conceito da integralidade em saúde e como operacionalizar na prática a integralidade na Atenção Básica. Considerando a integralidade como um dos pilares do SUS e tomando a força de trabalho em enfermagem como um contingente considerável de pessoas para operar na construção do SUS, considerou-se importante identificar as bases conceituais e práticas que direcionam o trabalho das enfermeiras para a construção da integralidade na saúde. Neste estudo qualitativo exploratório, foram entrevistadas 10 enfermeiras que atuam na atenção básica em três municípios do interior do estado de São Paulo. Os dados foram coletados através de entrevistas semiestruturadas e analisados segundo a técnica do discurso do sujeito coletivo. Os resultados mostraram que as concepções que as enfermeiras possuem sobre integralidade estão diretamente relacionadas à prestação de assistência e que estas profissionais colocam a integralidade em prática ao executar seu processo de trabalho cotidiano.

    2012-03-01

    Full Text Available Adolescentes e jovens constituem importante desafio para a construção da integralidade na Atenção Primária à Saúde (APS. Isso se deve à complexa apreensão e resposta ao conjunto de suas necessidades de saúde, decorrentes do processo de crescimento e desenvolvimento, próprio da fase, mas, sobretudo, dos aspectos socioculturais relacionados. O presente estudo buscou reconhecer alcances e limites em como o princípio da integralidade vem sendo operado em uma Unidade Básica de Saúde. Embora tenha sido possível identificar uma efetiva percepção da especificidade necessária à atenção à saúde desse grupo, também se verificaram importantes limitações relacionadas à construção de projetos de cuidado capazes de integrar as diversas finalidades do trabalho no cotidiano da Unidade, com destaque para a insuficiência de interações profissionais e setoriais, e fragilidades na comunicação de profissionais entre si e de profissionais e usuários.

MÉTODOS: Estudo qualitativo com abordagem dialética. Os dados foram coletados por meio da observação participante e de entrevista com gestores, docentes e discentes, sendo analisados pela técnica de Análise de Conteúdo Temática. RESULTADOS: Evidenciaram-se práticas de gestores e profissionais que contribuem para a integralidade do cuidado ao neonato, tais como a descentralização das ações de gestão, a tomada de decisão em conjunto com os profissionais, o incentivo ao trabalho em equipe e a valorização da família. Foi apontada a integração dos profissionais do serviço no processo de ensino-aprendizagem como estratégia para uma formação norteada pela integralidade. CONCLUSÃO: Verifica-se a necessidade de articulação entre gestão, assistência e formação para a construção de um cuidado pautado na integralidade.

    Maria Luiza Paz Machado

    Full Text Available Objetivou-se analisar uma intervenção no modo tradicional de ensinar a consulta de enfermagem e seu potencial para a formação de enfermeiros para a prática da integralidade em saúde. Pesquisa participante, desenvolvida com oito alunos do Curso de Enfermagem de uma universidade pública do sul do Brasil, no período de agosto a novembro de 2011. O contexto de estudo constituiu-se pelas consultas ambulatoriais e por vivências no cotidiano dos usuários. Os dados coletados por meio de grupo focal foram submetidos à análise temática, emergindo duas categorias: "A interatividade entre o cenário tradicional e o ampliado: possibilidades para o aprendizado da integralidade" e "A consulta de enfermagem ampliada: saberes gerados na experiência". Evidenciou-se que a experiência foi produtora de saberes coerentes com a formação para integralidade. Conclui-se que a diversificação de cenários de aprendizagem pode configurar-se como estratégia pedagógica com potência para provocar transformações no modelo de atenção/formação em saúde vigente.

    Full Text Available En esta investigación se evaluó la práctica de la integralidad a partir de la salud del niño. Es un estudio de caso exploratorio-descriptivo (de naturaleza transversal, con abordaje cuantitativo, desarrollado en dos unidades de salud: una cuyo eje estructural era el Programa Salud de la Familia, y, otra, que organizaba la asistencia según el modelo tradicional. Los datos fueron recolectados mediante entrevistas con padres/responsables por los niños (n=195, y analizados con el teste qui-cuadrado y t-student. El acceso en las dos unidades era difícil, con un promedio de 2 a 3 idas al servicio para pedir consulta. El acceso a los medicamentos y el sistema de referencia/contra-referencia fue mejor garantizado en la unidad de salud de la familia. El principio de la integralidad no se mostró incorporado, ni mismo en la unidad de salud de la familia. Siendo así, aún permanecen como desafíos, la búsqueda de modelos asistenciales que incorporen el acceso a los servicios de salud y la práctica de la integralidad.

    Full Text Available Objetivou-se com este estudo analisar as ações de saúde desenvolvidas por equipes de saúde da família em um município do sudeste goiano à luz da integralidade. Trata-se de pesquisa exploratória descritiva de abordagem qualitativa. A coleta de dados foi realizada por meio de entrevistas e, após uma análise de conteúdo, elegeram-se três categorias temáticas: Ações dos trabalhadores e articulação entre elas; A ESF não funciona como Estratégia Saúde da Família;Atualização das equipes de saúde da família. Os resultados demonstram a fragmentação das ações e desarticulação entre os trabalhadores, o que dificulta a integralidade. Concluiu-se, assim, que existe uma necessidade de investimentos na educação permanente em saúde, no fortalecimento do controle social, na avaliação participativa no SUS e no aprimoramento de tecnologias de gestão e cuidado.

    Full Text Available Estudio más detallado del cuidado diario del recién nacido de riesgo. Propone abarcar cómo interfiere el proceso de comunicación interpersonal en la práctica de la integralidad del cuidado al recién nacido internado en la Unidad de Cuidados Intensivos Neonatal. Se optó por el enfoque cualitativo, orientado por el marco teórico-metodológico de la dialéctica y como estrategia de aprehensión de la realidad en base a la observación participante y grupo focal con los profesionales. Estudio elaborado en una maternidad del municipio de Belo Horizonte, Minas Gerais. El análisis de los datos revela que las relaciones de poder intrínsecas al cotidiano del cuidado dialógico deben verse como posibilidades de negociaciones permanentes y de cambios al actuar en la salud. La comunicación fue identificada como estrategia para el logro de acciones integrales. Por lo tanto, es evidente la necesidad de crear espacios para que ella ocurra, con miras a que el cuidado se centre en el recién nacido y su familia.

    Full Text Available Trata-se de pesquisa qualitativa que analisou as representações sociais dos profissionais da Estratégia Saúde da Família (ESF do Distrito Federal-DF acerca da integralidade do cuidado. A ESF vem sendo implantada no Brasil desde 1994 como uma estratégia política para reordenar o modelo de atenção à saúde, estando atualmente em processo de ampliação no DF. Foram realizados entrevistas individuais semiestruturadas e grupo focal com gestores locais e profissionais das equipes de 11 das 15 regionais de saúde. Utilizou-se o Discurso de Sujeito Coletivo (DSC e a teoria das Representações Sociais para análise, com o objetivo de compreender a sociogênese da forma de pensar a partir de um olhar psicossocial sobre a realidade. Verificou-se que o cuidado é percebido como ato de solidariedade e atributo profissional, apoio às famílias em suas múltiplas necessidades e articulação de ações interdisciplinares de prevenção, promoção e tratamento, visando qualidade de vida. A integralidade do cuidado permeia a noção de autonomia profissional, requer a criação de vínculos de confiança e responsabilização entre profissionais e usuários, a contextualização da família sobre os determinantes e formas de enfrentamento dos problemas e demanda a integração com demais serviços. O estudo demonstrou que o cuidado relaciona-se com diferentes dimensões da integralidade, refletindo potencialidades e desafios do modelo da ESF para o desenvolvimento de práticas ampliadas de saúde. Faz-se necessário que a potencialidade das relações estabelecidas entre diferentes sujeitos no território permita a qualificação das ações de saúde, sobretudo aquelas voltadas para a promoção.This qualitative research analyzed the social representations about comprehensive care of the health professionals who work at the teams of the Family Health Strategy (ESF in Distrito Federal - DF, Brazil.

Representa ampliação dos conceitos saúde e doença, abarcando os determinantes sociais das necessidades em saúde. Pesquisa com o objetivo de investigar os significados de Integralidade apresentados por trabalhadores da Atenção Primária foi desenvolvida em munícipio de médio porte paulista, envolvendo distintos modelos tecnológicos de organização do trabalho nas Unidades Básicas de Saúde. Dentre os resultados, a dimensão de Integralidade do Sistema apresentou-se com maior frequência, conforme análise a partir de grupos focais. Os trabalhadores apontaram dificuldades de integração e comunicação entre os níveis de atenção à saúde, determinadas por políticas sociais seletivas e serviços de média/alta tecnologia delegados ao mercado privado. Os aportes teórico-filosóficos do estudo pautaram-se na Psicologia Histórico-Cultural, a partir das categorias: trabalho/atividade; consciência; mediação e totalidade.

    Full Text Available Este artigo tem como objetivo problematizar a pertinência de uma política de saúde para a população de Gays, Lésbicas, Bissexuais, Travestis e Transexuais - GLBT. A partir da consideração dos processos de violação de seus direitos humanos, sistematicamente comprometidos devido a estigmas e processos discriminatórios, busca-se evidenciar a necessidade de uma política de saúde específica a esta população, na perspectiva da integralidade da atenção e da eqüidade no sistema de saúde. O desafio da construção de uma política de atenção integral à saúde dessa população, tal como prevista no programa de governo federal Brasil sem Homofobia, implica a complexificação e alargamento do que se compreende por direitos sexuais e reprodutivos para a efetiva promoção da eqüidade e universalidade do acesso aos bens e serviços.This paper discusses whether a specific health policy for Gays, Lesbians, Bisexuals, Transvestites and Transsexuals is a good way to improve their lives and health situation, recognizing that their human rights are systematically violated by prejudice and discrimination processes. A health policy could be a strong political and technical instrument for achieving integrality in health care and equity in the health system. Building a health policy according to the constitutional right of universality and integrality in health care is proposed by the Federal Government's program called No Homophobia in Brazil. For its consolidation, we need to broaden what we understand by sexual and reproductive rights.

    Full Text Available A integralidade tem norteado processos de mudanças, na formação do enfermeiro. Assim, é importante conhecer as iniciativas em cursos de Graduação em Enfermagem, com foco nesse princípio. Trata-se de um estudo descritivo-exploratório, com objetivos de analisar as concepções de integralidade presentes, nos discursos dos docentes, e as estratégias utilizadas para a apreensão de integralidade pelos alunos. Participaram docentes de três Instituições de Ensino Superior (IES existentes no Estado de Goiás, que haviam integralizado pelo menos um currículo, no ano de 2005. A coleta de dados ocorreu nas respectivas instituições, entre abril e setembro de 2006, após agendamento prévio. Compuseram o estudo onze docentes do gênero feminino, com idade entre 40 e 55 anos, com experiência em docência, variando de 15 a 32 anos e a maioria portadora de Pós-Graduação Stricto-Sensu. As entrevistas e os planos de ensino dos docentes representantes das áreas das Ciências da Enfermagem (Fundamentos de Enfermagem, Assistência de Enfermagem, Administração de Enfermagem e Ensino de Enfermagem foram analisados segundo Bardin (2003. Por meio da análise, emergiram três concepções de integralidade: Integralidade do Cuidado: do singular ao global; Integralidade do Cuidado: os caminhos para o SUS e Integralidade do Cuidado: estratégias para a ensinagem. Os sentidos da integralidade do cuidado mostraram-se inovadores, à medida que valorizam o singular, o global e os caminhos para o SUS. Manifestam os sentidos, prestando o cuidado ao ser humano na sua realidade social, com as suas especificidades e subjetividades, considerando as redes de cuidado e sociais em que estão inseridos. Como estratégias para a ensinagem, buscam desenvolver o aprender a aprender e fazer e aprender a ser e viver junto, possibilitando meios para que os educandos apreendam todos os sentidos manifestos pelos docentes. Esperamos que os resultados, desta pesquisa, possam

    Full Text Available A integralidade é um princípio do SUS, com várias perspectivas, entre as quais a da articulação de seus serviços. O debate sobre esse princípio está presente na assistência à saúde, com destaque para a área de Saúde da Mulher, e nas diretrizes da Vigilância Sanitária. Como as duas áreas buscam a qualidade dos serviços de saúde, o objetivo é analisar a integração entre Vigilância Sanitária e assistência à saúde da mulher. Trata-se de estudo de caso, qualitativo, com entrevistas de profissionais de Vigilância Sanitária de serviços de saúde e coordenadores de Saúde da Mulher (CSM. Os achados apontam para isolamento da Vigilância Sanitária nas secretarias de saúde. A importância da integração é citada por CSM, porém não é fácil de ser aplicada. As relações, se ocorrem, são por situações emergenciais. Os trabalhadores de Vigilância Sanitária acham que não há articulação por não haver problemas na Saúde da Mulher que demandem sua participação e que, com inspeções e palestras, estão colaborando com a área. Mostram-se dificuldades à concretização da integralidade, com o desafio de articular ações em saúde, sobretudo para a Vigilância Sanitária.Comprehensiveness is a key principle in Brazil's Unified National Health System (SUS, approached from various perspectives, including linkage between services. The debate on this principle appears in health care, especially in the area of Women's Health, and in Health Surveillance guidelines. Since both areas target quality of health services, the aim of this study is to analyze the integration between Health Surveillance and Women's Health Care. This is a qualitative case study that interviewed Health Surveillance staff in health services and coordinators of Women's Health services. The findings point to the isolation of Health Surveillance within the health secretariats. The importance of integrating the two areas is cited by Women's Health

Este estudo teve o objetivo de analisar a integralidade da atenção à saúde em Serviços de Assistência Especializada em HIV/Aids (SAE-HIV/Aids de Recife/Pernambuco, a partir do processo e organização do trabalho em equipe. Trata-se de um estudo de caso desenvolvido em três unidades de SAE-HIV/Aids, com base em abordagem qualitativa, por meio de diferentes técnicas de investigação. Os resultados apontam que os SAE atendem a grande parte das recomendações do Ministério da Saúde, sobre a infraestrutura básica, mas nenhum serviço apresentava a constituição da equipe mínima satisfatória. Há o reconhecimento da fragmentação do trabalho em equipe e da dificuldade de sistematizar uma prática interdisciplinar e intersetorial, sendo apontadas falhas para garantir o fluxo de referência e contrarreferência. Identificou-se pouca valorização do papel do gerente como articulador da equipe; a necessidade de perceber o usuário como um todo; e de a equipe trabalhar de forma articulada, buscando a prática comunicativa e as atividades relacionais.The complexity of providing healthcare to people with HIV/Aids requires investment in comprehensive action and care, constituting a challenge for the multidisciplinary work teams to build an interdisciplinary practice.

Os resultados revelam que a prática é organizada através de ações individuais e coletivas, construídas por uma demanda reprimida. O atendimento é fragmentado com a valorização excessiva da técnica e da especialidade, cujo eixo é ordenado pelo modelo médico-centrado, com resolubilidade limitada. O acolhimento é manifestado através de uma relação tensa e conflitante, porém com potencialidade para construir alternativas de mudança.

Objetivo: Comparar as medidas de velocidade autosselecionada no solo, na esteira rolante e a velocidade ideal estimada pelo número de Froude em sujeitos amputados transfemorais. Método: Primeiramente foi determinada a velocidade no solo; em seguida, realizou-se o teste na esteira, e a velocidade ideal foi estimada a partir dos dados antropométricos. Todos os sujeitos utilizavam joelho hidráulico e pé em fibra de carbono. Para comparação entre as velocidades foi realizada ANOVA de duas vias. Resultados: A velocidade autosselecionada na esteira foi menor (22% do que no solo. Tanto a velocidade autosselecionada na esteira como a do solo foram 44% e 22% menores do que a velocidade ideal estimada, respectivamente. Conclusão: As velocidades analisadas no presente estudo foram diferentes, provavelmente, devido à variação dos parâmetros cinemáticos.

    Full Text Available Neste texto, partimos do pressuposto de que a integralidade da atenção é um eixo prioritário da investigação e avaliação dos serviços e sistemas de saúde, estruturados como redes assistenciais interorganizacionais que articulam dimensões clínicas, funcionais, normativas e sistêmicas em sua operacionalização, reconhecendo que nenhuma organização reúne a totalidade dos recursos e competências necessárias para a solução dos problemas de saúde de uma população, em seus diversos ciclos de vida. Em virtude da complexidade desse "sistema sem muros", que elimina as barreiras de acesso entre os diversos níveis de atenção, em resposta às necessidades de saúde nos âmbitos local e regional, julgamos oportuno compartilhar algumas "lições preliminares" aprendidas em experiências pessoais e na literatura sobre a integração de serviços, que nos parecem de interesse comum aos pesquisadores e gestores comprometidos com a sua implantação.The premise of this paper is that comprehensive health care is a major component in the investigation and evaluation of health services and systems, structured as inter-organizational health care networks articulating clinical, functional, normative, and systemic dimensions in their operationalization and based on the understanding that no organization combines all the necessary resources and capabilities to solve the health problems of a population with its various life cycles. Given the complex nature of this "system without walls", eliminating barriers to access in the various health care levels in response to local and regional health, we take this opportunity to share a few "preliminary lessons" from our experience and from the literature on integrated health services which may interest researchers and managers concerned with the implementation of such services.

Totalizaram 09 artigos publicados no período de 2010 a 2012. A análise dos materiais se deu através da análise de conteúdo de Bardin. Resultados e Discussão: Mostrou-se a necessidade de que a enfermagem reconheça a integralidade como norteadora de suas práticas de saúde, valendo-se do trabalho vivo em saúde para a produção do cuidado. Ao mesmo tempo em que identifiquem em seu cotidiano as várias formas de efetuá-lo, garantindo assistência de qualidade, cuidado, corresponsabilização, vínculo e intersetorialidade, na medida em que se busca a longitudinalidade do cuidado em saúde.

    Paulo José Carvalho da Silva

    Full Text Available A arte de consolar alguém que sofre tem uma longa história. Alguns pensadores tornaram-se uma referência fundamental no Ocidente e seus escritos exerceram importante influência, sobretudo na tradição da medicina da alma. É o caso de Sêneca, herdeiro inovador do estoicismo antigo, que escreveu a Consolação a Márcia (Ad Marciam de Consolatione entre os anos 37 e 41, na Roma sob o governo de Calígula. Essa carta pública endereçada a uma nobre dama romana que perdera um filho é considerada a obra mais antiga conhecida e datada desse homem político e pensador, nascido em Córdova, no ano 4 a.C e morto no ano 65, e é, sem dúvida, um texto de grande interesse para a compreensão da antiga prática da consolação.

    Full Text Available O estudo da anorexia nervosa sob uma perspectiva histórica visa contribuir para a investigação daquilo que se configura como influência cultural na gênese e manutenção do quadro, além de questionar posições segundo as quais a anorexia nervosa seria um "mal da modernidade" ou decorrente de um único fator. Uma análise da vida das santas da Idade Média, por exemplo, mostra quanto o comportamento perseverante as aproxima das anoréxicas de hoje, ainda que a motivação e os ideais (ascético nas primeiras e estético nas últimas sejam diferentes.

    Full Text Available A atenção básica de saúde, impulsionada pela estratégia da saúde da família, tem o grande desafio de incorporar de ações de enfrentamento às situações de violência e problemas de saúde mental. O trabalho analisou a atenção prestada a 411 crianças de cinco a onze anos em uma UBS na cidade de São Paulo. Os dados clínicos foram comparados com um inventário de sintomas padronizados Child Behavior Checklist (CBCL. Entrevistas semi-estruturadas foram aplicadas complementarmente em pediatras. O trabalho mostra que os pediatras têm baixa capacidade de reconhecer problemas de saúde mental em crianças. Os principais fatores relacionados a este baixo desempenho foram: deficiência na formação, carência de possibilidade de atuação concreta frente à queixa ou hipótese diagnóstica. O processo de reorganização do trabalho na atenção básica deveria contemplar a oferta de apoio técnico específico em saúde mental, propiciando a incorporação de tecnologias de intervenção mais apropriadas, como acolhimento e escuta qualificada. A incorporação dos aspectos psicossociais na prática cotidiana da atenção básica possibilitará a ampliação do conceito saúde-doença e abrirá caminho para a abordagem das situações de violência às crianças atendidas na rede básica de serviços de saúde do SUS.A great challenge for the primary healthcare system, implemented by the strategy called the Family Health Program, is to incorporate actions for facing situations of violence and mental health problems. This study analyzed the care delivered to 411 children between five and eleven years of age in a primary care unit in the city of São Paulo. The clinical findings were compared to a standard inventory of symptoms (CBCL. In addition, semi-structured interviews were held with pediatricians. The study shows low capacity of the pediatricians to recognize mental health problems in children. This is mainly due to deficiencies in

    Full Text Available The incorporation of the environmental issue by international offices and regional blocks in the last decades, has demonstrated a growing preoccupation with the road to sustainable socio-economic development. The contemporary development process, consolidated by the capitalist production model, has exercised great influence on society in general. This globalized economic model gave rise to a new network of relations which have affected the political structures of the States. Thus, among the many concerns involving these changes is the incorporation of environmental values to reach sustainable development, to promote economic development taking into account environment protection and social justice. In face of the transnacionality issue and the importance of the objective at hand, it is fundamental to raise people’s awareness of the legal harmonization issue.A incorporação do tema ambiental por organismos internacionais e blocos regionais, ao longo das últimas décadas do século XX, demonstra uma lenta preocupação com o caminho do desenvolvimento sócio-econômico sustentável. O processo de desenvolvimento, que se consolidou a partir do modo de produção capitalista, exerceu influência sobre a sociedade de um modo geral. Um modelo econômico de efeito globalizante, trouxe à tona uma nova rede de relações, com reflexos, inclusive, nas estruturas políticas dos Estados. Assim, entre as necessárias preocupações, diante das mudanças, está a incorporação de valores relacionados ao meio ambiente para alcançar o desenvolvimento sustentável, ou seja, desenvolvimento econômico com preservação do meio ambiente e justiça social. Diante da transnacionalidade da questão ambiental e para alcançar tal objetivo, é fundamental despertar para a consciência do caminho da harmonização legislativa.

O Programa de Agentes Comunitários de Saúde/Programa Saúde da Família (PACS/PSF constitui estratégia para avançar nas mudanças requeridas, o que motivou esta investigação científica, que teve como objetivos conhecer o processo de cuidado pré-natal a adolescentes grávidas por profissionais de saúde do PACS/PSF e analisá-lo na perspectiva da integralidade. É um estudo qualitativo, tendo a integralidade como enfoque teórico. Foi desenvolvido em unidades de PACS/PSF em um município da Bahia, sendo sujeitos do estudo profissionais que cuidam de gestantes adolescentes. O material empírico foi produzido por meio de entrevista semiestruturada e observação não participante, em consultas e visitas domiciliárias e analisado pela técnica de análise de discurso. A análise revelou que o cuidado pré-natal à adolescente se concretiza sob o modelo biomédico, e o cumprimento de rotinas e protocolos institucionais sobrepõe-se à singularidade da adolescente. Assim, distancia-se da integralidade, na medida em que as práticas são orientadas por sujeições ideológicas a um modelo que nega às adolescentes grávidas a oportunidade de serem sujeitos.Prenatal adolescent care is characterized by technical actions seeking to provide assistance from the perspective of comprehensive care. The Community Health Agent Program/Family Health Program (PACS/PSF is a strategy for implementing the changes envisaged, which motivated this scientific investigation.

    Full Text Available Resumo: O mercado de combustíveis tem sido amplamente estudado sob várias perspectivas, desde a questão da assimetria e transmissão de preços, formação de cartéis, dinâmica de preços atrelada às flutuações na economia internacional, sistemas de demanda, entre outras. Neste sentido, este artigo tem como objetivo estimar um sistema de demanda para gasolina comum, etanol hidratado e óleo diesel via modelo (LA-AIDS Linear Approximation Almost Ideal Demand System com dados de séries temporais trimestrais para o período de 2001 a 2015 para o estado de Pernambuco. As estimações foram feitas por meio do método (SUR Seemingly Unrelated Regressions. Os resultados encontrados são semelhantes aos observados na literatura, no sentido em que apontam para a inelasticidade-preço da demanda da gasolina e diesel, o que é esperado dada a essencialidade dos bens. Também foi possível verificar que a demanda por etanol é elástica por ter elasticidade-preço marshalliana maior que um em valor absoluto, convergindo para os resultados já encontrados em outros estudos.

Este estudo é parte de uma pesquisa qualitativa que objetiva identificar dimensões individuais, sociais e programáticas da dupla vulnerabilidade de quinze mulheres com diferentes tipos e graus de deficiência, usuárias de três serviços de atenção básica em saúde na cidade de São Paulo. Destacam-se em suas narrativas vivências de rejeição ou superproteção familiar, dificuldades em adquirir equipamentos para sua autonomia, pouco investimento no estudo e na qualificação profissional, menor participação social, obstáculos à vivencia da sexualidade e da maternidade, falta de acessibilidade física, comunicacional e atitudes pouco receptivas nos serviços de saúde, caracterizando total vulnerabilidade. Problematizá-la possibilita a construção de práticas integrais de saúde que incorporem a dimensão dos direitos humanos de grupos que historicamente experimentam a violação dos mesmos: mulheres e pessoas com deficiência.Women with disabilities have few measures geared to their needs in the primary health care services.

    Full Text Available Passados 13 anos do surgimento do Sistema Único de Saúde, o governo federal aumentou o uso de normas e regulações que visam racionalizar os recursos e priorizar o nível de Atenção Básica dentro do sistema. Isso significa dizer que, embora as ações e serviços sejam de responsabilidade do município, a instância federal reforçou, mediante o financiamento, seu papel na determinação da política a ser adotada. Na primeira parte do artigo, analisa-se a evolução do gasto e do financiamento da atenção à saúde no país, as prioridades e as estratégias de financiamento. Na segunda parte, relaciona-se a Norma Operacional Básica de 1996 com a política de transferência de recursos para os municípios, adotada pelo governo federal; discuti-se a importância assumida pelo Programa Saúde da Família no interior da lógica do financiamento e destaca-se o papel da Norma Operacional da Assistência à Saúde no reforço da racionalização e da ênfase na Atenção Básica.Thirteen years after the Unified National Health System was implemented in Brazil, the Federal government increased the use of norms and regulations aimed at rationalizing resources and prioritizing basic care within the system. In other words, although actions and services are the responsibility of Municipal governments, the Federal government used financing to reinforce its role in determining the policy to be adopted. The first part of this article analyzes trends in health care expenditures and financing in the country and priorities and strategies for financing. The second part relates the 1996 Basic Operational Norm to the Federal government policy of transferring resources to the Municipalities, discussing the importance of the Family Health Program as part of the financing logic and the role of the Health Care Operational Norm in reinforcing rationalization and emphasizing basic care.

    Full Text Available Resumo Na perspectiva da pesquisa qualitativa e das teorias de gênero, este estudo tem como objetivo identificar e analisar as concepções de profissionais de saúde que atuam em uma equipe multidisciplinar em oncologia acerca da assistência oferecida ao público masculino com câncer. Foram entrevistados dez profissionais de saúde que compõem uma equipe multidisciplinar de um hospital oncológico de Belo Horizonte, em Minas Gerais. Os resultados indicam que, para os entrevistados, os homens configuram-se como um público resistente e de difícil atuação, exigindo um manejo distinto daquele oferecido às mulheres. A dimensão biológica e o processo de socialização foram apontados como elementos que contribuem para esse distanciamento. Constatou-se ainda que os discursos dos profissionais de saúde também se encontram atravessados por estereótipos de gênero. Observam-se maior ênfase às necessidades das mulheres e o não reconhecimento dos homens como sujeitos das políticas de saúde e ações assistenciais. Faz-se necessária a inclusão do tema das masculinidades na pauta de discussões dos serviços de saúde em oncologia, favorecendo a construção participativa de estratégias que possibilitem o reconhecimento das necessidades masculinas e a garantia de práticas de saúde orientadas pelo princípio da integralidade.

A few millimeters can make the lateral view aesthetically more or less pleasing and adequate in a subject's face. Professionals working with facial aesthetics should focus not only on the surgical techniques for proposed outcomes, but also with the subtleties and subjectivity that characterize aesthetic concepts and judgment. MATERIAL AND METHODS: A prospective survey to evaluate the preferences of a group of healthcare professionals working with facial aesthetics, a group of fine artists, and lay people about the best nasal radix height; the survey involved comparing 3 different nasal radix heights using computer-altered photographs of women with measurements close to the Caucasian standard. RESULTS AND CONCLUSION: The lowest position of the nasal radix - close to the height of the pupil - was preferred (53%, followed by the middle position (superior crease of the eye. The highest position, resembling classic Greek statues, was considered the worst. The authors aos evaluated the effect of age, gender, and educational level on the choice of the best and worst female profiles.A harmonia facial da visão de perfil é muito influenciada pela altura e forma do dorso nasal.

    Full Text Available Ética e estética são duas dimensões absolutamente imbricadas no pensamento musical grego. Os princípios morais contidos, por exemplo, na teoria do éthos musical norteiam a apreciação das formas musicais, seja no que se refere à escolha dos instrumentos, dos gêneros, ou dos modos musicais (escalas. A importância que os gregos conferiam a esta intersecção entre a estética e a ética na música assumia grande relevância política, como pode ser verificado no destaque dado à educação musical. Ao avaliar a biografia dos principais homens públicos atenienses, recorrendo-se a obras como as Vidas Paralelas de Plutarco, constata-se o quanto se valorizava a influência da formação musical sobre as qualidades políticas e morais de um cidadão. Considerava-se que a música desempenhava importante papel para a constituição da virtude da kalo-kagathía (beleza-bondade, que era considerada o bem maior para um cidadão: o reconhecimento do belo e de escolha do bom, do justo. Vê-se, assim, a existência de uma pedagogia política, calcada nas noções de ética e estética, na qual o ensino musical merecia bastante atenção, como demonstram as recomendações de Platão e Aristóteles.

  17. Non-ideal dust acoustic waves

    Konefka, F; Contreras, J P; Puerta, J; Castro, E; MartIn, P

    2008-01-01

    The dispersion relation for dust acoustic waves (DA waves) functionally depends on the state equation for the charged dust grains. The ideal gas equation is usually used for studying the effect of temperature on this dispersion relation. However, since the space occupied by the grains can be important in high-density plasmas, the non-ideal effects can be important in this case. This paper analyses the dispersion relation for DA waves, when more precise state equations are used as those described for Pade approximants. The correction to the usual wave equation has been determined and the break point in density, where the ideal gas-state equation has been found. The non-ideal effects are more important for short wavelength ones, and the limits where those effects become important are also studied. Since there are several experimental results for these kinds of waves, the importance of the non-ideal effects in these cases is analysed in detail.

    Full Text Available OBJECTIVES: To describe the new IDEAL method from classifying distal radius fractures. METHODS: IDEAL classification system is based on the most important literature evidences about clinical and radiographic characteristics that influence in the treatment and prognosis for patients that suffered from a distal radius fractures. In this method, we classify the fracture in patients first consultation, in which we collect demographical (age and trauma energy and radiographic characteristics ( fracture deviation, articular fracture, and associated lesions. For each feature a score is attributed for grouping purposes. Group I - Stable fractures, good prognosis; Group II - potentially unstable fractures, commonly treated by surgical methods. Prognosis depends on surgeons' success after method choice. Group III - complex and instable fractures, poor outcome is expected. CONCLUSION: IDEAL classification staging rationale was presented, which is based on the best available evidence. The evidence of its scientific plausibility will be settled with the assessment of the classification reliability and its capacity to aid in therapeutical decisions and as a tool to predict prognosis. Further studies are under development to support these properties. OBJETIVOS: Descrição do método de Classificação IDEAL - para as fraturas da extremidade distal do rádio. MÉTODOS: O sistema de classificação IDEAL fundamenta-se nas principais evidências da literatura sobre fatores clínicos e radiográficos que influenciam o tratamento e prognóstico das fraturas do rádio distal. Classificamos as fraturas no atendimento inicial do paciente mediante a verificação de dois dados epidemiológicos e três dados radiográficos: Idade do paciente, energia do trauma, desvio dos fragmentos, incongruência articular e lesões associadas. RESULTADOS: Conforme a pontuação obtida, agrupamos os casos em três grupos: Grupo I - fraturas estáveis com bom prognóstico, Grupo II

    Full Text Available A atuação interprofissional em saúde tem se constituído de um elemento importante para a produção das ações de saúde na perspectiva de cuidado integral. Este estudo analisou a atuação interprofissional na terapia intensiva segundo Habermas. Insere-se na abordagem qualitativa, elegendo o estudo de caso como modalidade de investigação. A captação do material empírico consistiu-se de observação do cenário e entrevistas semiestruturadas junto aos trabalhadores de saúde. Para análise das informações utilizou-se a técnica de interpretação de sentidos. A análise nos permitiu identificar dois eixos temáticos: o cuidado individual instrumental frente às instabilidades clínicas e o cuidado coletivo fragmentado por funções. Tal resultado fragiliza a interação entre trabalhador/trabalhador e trabalhador/paciente e compromete a articulação das ações de saúde. Por não favorecer espaços de encontros à ação comunicativa, esta fica frágil e a ação estratégica/instrumental se evidencia.

Este trabalho objetivou compreender a experiência de enfermeiras que atuam em uma unidade de terapia intensiva neonatal. A coleta de dados foi realizada em 2008, por meio de entrevistas com 12 enfermeiras que atuavam em hospitais públicos e privados da cidade de São Paulo. As unidades de significado identificadas foram agrupadas em três categorias: desenvolvendo ações, percebendo suas ações e expectativas. A análise foi fundamentada na fenomenologia social. Conclui-se que a sobrecarga de atividades, o reduzido número de pessoal, a falta de materiais, equipamentos e a necessidade de aprimoramento profissional são a realidade do trabalho da enfermeira nesse setor. Supervisionar os cuidados é o possível; cuidar integralmente do recém-nascido, envolvendo seus pais, é o ideal almejado.

  3. Space Sciences and Idealism

    Popov, M.

    Erwin Schrodinger suggested that " Scientific knowledge forms part of the idealistic background of human life", which exalted man from a nude and savage state to true humanity [Science and Humanism, Cambridge, 1961, p9]. Modern space sciences an space exploration are a brilliant demonstration of the validity of Schrodinger's thesis on Idealism. Moreover, Schrodingers thesis could be considered also as a basic principle for the New Educational Space Philosophical Project "TIMAEUS"."TIMAEUS" is not only an attempt to to start a new dialogue between Science, the Humanities and Religion; but also it is an origin of the cultural innovations of our so strange of globilisation. TIMAEUS, thus, can reveal Idealism as something more fundamental , more refined, more developed than is now accepted by the scientific community and the piblic. TIMAEUS has a significant cultural agenda, connected with the high orbital performance of the synthetic arts, combining a knowledge of the truly spiritual as well as the universal. In particular, classical ballet as a synthetic art can be a new and powerful perfector and re-creator of the real human, real idealistic, real complex culture in orbit. As is well known, Carlo Blasis, the most important dance theorist of the 19t h .century, made probably the first attempts to use the scientific ideas of Leonardo da Vinci and Isaac Newton for the understanding of the gravitational nature of balance and allegro in ballet. In particular Blasis's idea of the limited use of the legs in classical dance realised by the gifted pupils of Enrico Cecchetti - M.Fokine, A.Pavlova and V.Nijinsky, with thinkable purity and elegance of style. V.Nijinsky in his remarkable animation of the dance of two dimensional creatures of a Euclidean flat world (L'Apres Midi d'un Faune,1912) discovered that true classical dance has some gravitational limits. For example, Nijinsky's Faunes and Nymphs mut use running on the heels (In accordance with "Partitura" 1916); they

    Full Text Available La enseñanza del inglés como lengua extranjera se ha convertido en factor predominante dentro del pensum de estudio de la mayoría de las carreras impartidas a nivel universitario, por considerarla como la lengua de la ciencia, tecnología, comunicación, entre otros. Esta premisa hace que su enseñanza se considere eje articulador de saberes, capaz de atravesar el mapa curricular en todos sus niveles para ofrecer una enseñanza más significativa, pertinente y humanística. Por lo cual, la presente investigación se planteó como objetivo determinar la percepción que tienen los estudiantes acerca del grado de integralidad curricular que poseen los materiales diseñados para la enseñanza de la lectura en inglés con el resto de las asignaturas que posee el pensum de estudio de la carrera de ingeniería de petróleo. Los resultados arrojados reportaron dicha percepción en un 50%, lo cual conduce a concluir que aún cuando los materiales diseñados para la enseñanza del inglés se encuentren relacionados con materias de la carrera, no es sino hasta que el alumno interactúe de manera continua con lo leído en inglés, cuando podrá decidir en qué medida esto que lee se relaciona con los objetivos y contenidos de otras asignaturas de su pensum en un 100%.

    Christopher P. Long

    2012-08-01

    Full Text Available This essay articulates the differences and suggests the similarities between the practices of Socratic political speaking and those of Platonic political writing. The essay delineates Socratic speaking and Platonic writing as both erotically oriented toward ideals capable of transforming the lives of individuals and their relationships with one another. Besides it shows that in the Protagoras the practices of Socratic political speaking are concerned less with Protagoras than with the individual young man, Hippocrates. In the Phaedo, this ideal of a Socrates is amplified in such a way that Platonic writing itself emerges as capable of doing with readers what Socratic speaking did with those he encountered. Socrates is the Platonic political ideal. The result is a picture of the transformative political power of Socratic speaking and Platonic writing both.

    2013-02-01

    Full Text Available We show that the thermodynamics of ideal gases may be derived solely from the Democritean concept of corpuscles moving in vacuum plus a principle of simplicity, namely that these laws are independent of the laws of motion, aside from the law of energy conservation. Only a single corpuscle in contact with a heat bath submitted to a z and t-invariant force is considered. Most of the end results are known but the method appears to be novel. The mathematics being elementary, the present paper should facilitate the understanding of the ideal gas law and of classical thermodynamics even though not-usually-taught concepts are being introduced.

    Full Text Available OBJECTIVE: Lithium has been successfully employed to treat bipolar disorder for decades, and recently, was shown to attenuate the symptoms of other pathologies such as Alzheimer's disease, Down's syndrome, ischemic processes, and glutamate-mediated excitotoxicity. However, lithium's narrow therapeutic range limits its broader use. Therefore, the development of methods to better predict its dose becomes essential to an ideal therapy. METHOD: the performance of adult Wistar rats was evaluated at the open field and elevated plus maze after a six weeks treatment with chow supplemented with 0.255%, or 0.383% of lithium chloride, or normal feed. Thereafter, blood samples were collected to measure the serum lithium concentration. RESULTS: Animals fed with 0.255% lithium chloride supplemented chow presented a higher rearing frequency at the open field, and higher frequency of arms entrance at the elevated plus maze than animals fed with a 50% higher lithium dose presented. Nevertheless, both groups presented similar lithium plasmatic concentration. DISCUSSION: different behaviors induced by both lithium doses suggest that these animals had different lithium distribution in their brains that was not detected by lithium serum measurement. CONCLUSION: serum lithium concentration measurements do not seem to provide sufficient precision to support its use as predictive of behaviors.OBJETIVO: Além de ser usado há décadas para tratar distúrbio bipolar, o lítio, mais recentemente, demonstrou-se eficaz para Alzheimer, síndrome de Down, processos isquêmicos e excitotoxicidade mediada por glutamato. Contudo, a estreita janela terapêutica do lítio limita seu uso. Portanto, o estabelecimento de métodos preditivos de dose torna-se importante.

In today's marketplace, occupational health nurses understand that differentiation (i.e., the perception of uniqueness) is the direct result of superior employee interactions, which lead to better employee care, enduring employee relationships, loyal employees, and satisfied employers. What drives employees to occupational health nurse attachment? The answer is a passion for rising above the competition to create ideal employee experiences.

    Directory of Open Access Journals (Sweden)

    Ivan Vuković

    2016-02-01

    Full Text Available The author examines possible analogies between Kant’s transcendental idealism and de Saussure’s and Levi-Strauss’s structuralism, in order to analyse if the former can be understood as a predecessor for the later. The author shows that both teachings assume a priori formal framework, but they diverge in the ways they describe it, as well as in understanding of its function. Consequently, the author concludes that structuralism can be seen as one possible use of Kant’s idea about the existence of such a frame. Furthermore, the author claims that Ricker’s understanding of structuralism as ‘Kantianism without transcendental subject’ should be rejected, since a teaching which does not assume existence of such subject cannot be understood as Kantian.

    In reaction to Doret De Ruyter's recent defence of the importance of ideals in education, I advocate cautiousness in three respects. First, I explain the importance of distinguishing ideals more sharply from goals by demonstrating the problems of considering ideals even approximately realisable.

  18. Monomial ideals, computations and applications

    Gimenez, Philippe; Sáenz-de-Cabezón, Eduardo

    2013-01-01

    This work covers three important aspects of monomials ideals in the three chapters "Stanley decompositions" by Jürgen Herzog, "Edge ideals" by Adam Van Tuyl and "Local cohomology" by Josep Álvarez Montaner. The chapters, written by top experts, include computer tutorials that emphasize the computational aspects of the respective areas. Monomial ideals and algebras are, in a sense, among the simplest structures in commutative algebra and the main objects of combinatorial commutative algebra. Also, they are of major importance for at least three reasons. Firstly, Gröbner basis theory allows us to treat certain problems on general polynomial ideals by means of monomial ideals. Secondly, the combinatorial structure of monomial ideals connects them to other combinatorial structures and allows us to solve problems on both sides of this correspondence using the techniques of each of the respective areas. And thirdly, the combinatorial nature of monomial ideals also makes them particularly well suited to the devel...

    Koenderink (2014, Perception, 43, 1-6) has said most Perception readers are deluded, because they believe an 'All Seeing Eye' observes an objective reality. We trace the source of Koenderink's assertion to his metaphysical idealism, and point to two major weaknesses in his position-namely, its dualism and foundationalism. We counter with arguments from modern philosophy of science for the existence of an objective material reality, contrast Koenderink's enactivism to his idealism, and point to ways in which phenomenology and cognitive science are complementary and not mutually exclusive.

    Full Text Available In this paper we study some geometric properties of the algebraic set associated to the binomial edge ideal of a graph. We study the singularity and smoothness of the algebraic set associated to the binomial edge ideal of a graph. Some of these algebraic sets are irreducible and some of them are reducible. If every irreducible component of the algebraic set is smooth we call the graph an edge smooth graph, otherwise it is called an edge singular graph. We show that complete graphs are edge smooth and introduce two conditions such that the graph G is edge singular if and only if it satisfies these conditions. Then, it is shown that cycles and most of trees are edge singular. In addition, it is proved that complete bipartite graphs are edge smooth.

    Full Text Available Some elements of the ideal of moral autonomy are discussed in this paper. Such ideal is a key assumption in social practices focused on normative imputation, particularly morality and law. First, a constructivist conception of normativity is introduced, taking reasons as an essential and non-reducible element, and focused on the conceptual features of moral reasons within the normative domain. Then, an idea of moral autonomy based on the self-constitution is developed including three key features: the possibility of responding to reasons based on shared social expectations; the responsibility for certain scope of actions, according to a set of reasons available to the individual and to their maximum extent of expansion; and the need to preserve autonomy as a purpose unifying the set of autonomous actions of moral agents.

    Nonimaging optics is a field devoted to the design of optical components for applications such as solar concentration or illumination. In this field, many different techniques have been used for producing reflective and refractive optical devices, including reverse engineering techniques. In this paper we apply photometric field theory and elliptic ray bundles method to study 3D asymmetric - without rotational or translational symmetry - concentrators, which can be useful components for nontracking solar applications. We study the one-sheet hyperbolic concentrator and we demonstrate its behaviour as ideal 3D asymmetric concentrator. (author)

    The formalism of statistical mechanics of particles slower than light has been considered from the point of view of the application of this formalism for the description of tachyons. Properties of ideal gases of tachyons have been discussed in detail. After finding general formulae for quantum, Bose and Fermi gases the classical limit has been considered. It has been shown that Bose-Einstein condensation occurs. The tachyon gas of bosons violates the third principle of thermodynamics. Degenerated Fermi gas has been considered and in this case the entropy vanishes at zero temperature. Difficulties of formulating covariant statistical mechanics have been discussed

Aim: our aim was to investigate the economic consequence of high dose of atorvastatin vs usual-dose of simvastatin in reducing major coronary events in patients with a history of acute myocardial infarction (AMI. Methods: the analysis is based on clinical outcome data from the IDEAL study. We conducted a cost-effectiveness analysis, comparing high dose of atorvastatin (80 mg/die versus usual-dose of simvastatin (20 mg/die in the perspective of the Italian National Health Service. We identified and quantified medical costs: drug costs according to the Italian National Therapeutic Formulary and hospitalizations were quantified based on the Italian National Health Service tariffs (2006. Effects were measured in terms of mortality and morbidity reduction (number of deaths, life years gained and frequency of hospitalizations. We considered an observation period of 4.8 years. The costs borne after the first 12 months were discounted using an annual rate of 3%. We conducted one and multi-way sensitivity analyses on unit cost and effectiveness. We also conducted a threshold analysis. Results: the cost of simvastatin or atorvastatin therapy over the 4.8 years period amounted to approximately 2.3 millions euro and 2.6 millions euro per 1,000 patients respectively. Atorvastatin was more efficacious compared to simvastatin and the overall cost of care per 1,000 patients over 4.8 years of follow-up was estimated at 4.3 millions euro in the simvastatin and 4,18 millions euro in the atorvastatin group, resulting into a cost saving of 121,518 euro that is 2.8% of total costs occurred in the simvastatin group. Discussion: this study is the first economic

    Full Text Available Today’s clothing industry is based on a system where clothes are made in ready-to-wear sizes and meant to fit most people. Studies have pointed out that consumers are discontent with the use of these systems: size designations are not accurate enough to find clothing that fits, and different sizes are poorly available. This article discusses in depth who these consumers are, and which consumer groups are the most dissatisfied with today’s sizing systems. Results are based on a web survey where 2834 Nordic consumers responded, complemented with eight in-depth interviews, market analysis on clothing sizes and in-store trouser size measurements. Results indicate that higher shares of the consumers who have a body out of touch with the existing beauty ideals express discontentment with the sizing systems and the poor selection available. In particular, large women, very large men, and thin, short men are those who experience less priority in clothing stores and have more difficulties in finding clothes that fit. Consumers tend to blame themselves when the clothes do not fit their bodies, while our study points out that the industry is to blame as they do not produce clothing for all customers.

  13. Practicing Identity: A Crafty Ideal?

    Science.gov (United States)

    Brysbaert, A.; Vetters, M.

    This paper focuses on the materialization of technological practices as a form of identity expression. Contextual analyses of a Mycenaean workshop area in the Late Bronze Age citadel of Tiryns (Argolis, Greece) are presented to investigate the interaction of different artisans under changing socio-political and economic circumstances. The case study indicates that although certain technological practices are often linked to specific crafts, they do not necessarily imply the separation of job tasks related to the working of one specific material versus another. Shared technological practices and activities, therefore, may be a factor in shaping cohesive group identities of specialized artisans. Since tracing artisans' identities is easier said than done on the basis of excavated materials alone, we employ the concepts of multiple chaînes opératoires combined with cross-craft interactions as a methodology in order to retrieve distinctive sets of both social and technological practices from the archaeological remains. These methodological concepts are not restricted to a specific set of steps in the production cycle, but ideally encompass reconstructing contexts of extraction, manufacture, distribution and discard/reuse for a range of artefacts. Therefore, these concepts reveal both technological practices, and, by contextualising these technological practices in their spatial layout, equally focus on social contacts that would have taken place during any of these actions. Our detailed contextual study demonstrates that the material remains when analysed in their entirety are complementary to textual evidence. In this case study they even form a source of information on palatial spheres of life about which the fragmentary Linear B texts, so far, remain silent.

  14. Improved Classification of Mammograms Following Idealized Training

    People often make decisions by stochastically retrieving a small set of relevant memories. This limited retrieval implies that human performance can be improved by training on idealized category distributions (Giguère & Love, 2013). Here, we evaluate whether the benefits of idealized training extend to categorization of real-world stimuli, namely classifying mammograms as normal or tumorous. Participants in the idealized condition were trained exclusively on items that, according to a norming study, were relatively unambiguous. Participants in the actual condition were trained on a representative range of items. Despite being exclusively trained on easy items, idealized-condition participants were more accurate than those in the actual condition when tested on a range of item types. However, idealized participants experienced difficulties when test items were very dissimilar from training cases. The benefits of idealization, attributable to reducing noise arising from cognitive limitations in memory retrieval, suggest ways to improve real-world decision making. PMID:24955325

    Rodriguez, Lindsey M; Hadden, Benjamin W; Knee, C Raymond

    2015-03-01

    The ideal standards model suggests that greater consistency between ideal standards and actual perceptions of one's relationship predicts positive relationship evaluations; however, no research has evaluated whether this differs across types of ideals. A self-determination theory perspective was derived to test whether satisfaction of intrinsic ideals buffers the importance of extrinsic ideals. Participants (N=195) in committed relationships directly and indirectly reported the extent to which their partner met their ideal on two dimensions: intrinsic (e.g., warm, intimate) and extrinsic (e.g., attractive, successful). Relationship need fulfillment and relationship quality were also assessed. Hypotheses were largely supported, such that satisfaction of intrinsic ideals more strongly predicted relationship functioning, and satisfaction of intrinsic ideals buffered the relevance of extrinsic ideals for outcomes.

  19. Ideal MHD B limits in the BIG DEE tokamak

    International Nuclear Information System (INIS)

    1983-01-01

    Using D-D reactions, tokamak reactors become economically attractive when B (the ratio of volume averaged pressure to magnetic pressure) exceeds 5 percent. Ideal MID instabilities are of great concern because they have the potential to limit B below this range and so extensive studies have been done to determine ideal MHD B limits. As B increases with inverse aspect ratio, elongation and triangularity, the Doublet III upgrade machine -- BIG DEE -- is particularly suited to study the possibility of very high B. The authors have done computations to determine ideal MHD B limits for various plasma shapes and elongations in BIG DEE. They have determined that for q at the plasma surface greater than 2, B is limited by the ballooning mode if the wall is reasonably close to the plasma surface (d/a < 1.5 where d and a are the wall and plasma radii respectively). On the other hand, for q at the plasma surface less than 2, the n=1 external kink is unstable even with a wall close by. Thus, relevant values of limiting B can be obtained by assuming that the external kink limits the value of q at the limiter to a value greater than 2 and that the ballooning modes limit B. Under this assumption, a relevant B limit for the BIG DEE would be over 18%. For such an equilibrium, the wall position necessary to stabilize the n=1 and n=2 modes is 2a and the equilibrium is stable for n=3

  10. Predicting film genres with implicit ideals

    2013-01-01

    Full Text Available We present a new approach to defining film genre based on implicit ideals. When viewers rate the likability of a film, they indirectly express their ideal of what a film should be. Across six studies we investigate the category structure that emerges from likability ratings and the category structure that emerges from the features of film. We further compare these data-driven category structures with human annotated film genres. We conclude that film genres are structured more around ideals than around features of film. This finding lends experimental support to the notion that film genres are set of shifting, fuzzy, and highly contextualized psychological categories.

  14. Surface dependency in thermodynamics of ideal gases

    2004-01-01

    The Casimir-like size effect rises in ideal gases confined in a finite domain due to the wave character of atoms. By considering this effect, thermodynamic properties of an ideal gas confined in spherical and cylindrical geometries are derived and compared with those in rectangular geometry. It is seen that an ideal gas exhibits an unavoidable quantum surface free energy and surface over volume ratio becomes a control variable on thermodynamic state functions in microscale. Thermodynamics turns into non-extensive thermodynamics and geometry difference becomes a driving force since the surface over volume ratio depends on the geometry

The characteristic solution to the problem in the neighbourhood of leading characteristics has been determined. An evolution equation governing the behaviour of acceleration waves has been derived. It is shown that a linear solution in the characteristic plane exhibits non-linear behaviour in physical plane. The effect of magnetic field on the formation of shock in non-ideal gas flow with planar and cylindrical symmetry is analysed. It is noticed that all compressive waves terminate into a shock wave. Further, we also compare/contrast the nature of solution in ideal and non-ideal magnetogasdynamic regime.

  18. Quantum surface tension in ideal gases

    International Nuclear Information System (INIS)

    Sisman, A.

    2005-01-01

    Due to wave character of atoms, an ideal gas confined in a finite domain exhibits Casimir like size effects. These effects become appreciable in a domain with at least one dimension in the order of micron. On this scale, thermodynamic state functions of an ideal gas become shape and size dependent and some new effects appear. In the literature, only some domains of regular shapes have been considered. In this study, the results are generalized to a domain of an arbitrary shape by using Weyl s conjecture for density of states. It is seen that free energy expression of an ideal Maxwellian gas consists of a classical volume dependent term and also a quantum originated surface dependent term, which causes a quantum surface tension. In a rectangular box filled by an ideal gas and separated by a movable wall into two parts, it is shown that a lateral force appears on the movable wall due to quantum surface tension

    Le Morvan, P; Stock, B

    2005-09-01

    A hitherto unexamined problem for the "Kantian ideal" that one should always treat patients as ends in themselves, and never only as a means to other ends, is explored in this paper. The problem consists of a prima facie conflict between this Kantian ideal and the reality of medical practice. This conflict arises because, at least presently, medical practitioners can only acquire certain skills and abilities by practising on live, human patients, and given the inevitability and ubiquity of learning curves, this learning requires some patients to be treated only as a means to this end. A number of ways of attempting to establish the compatibility of the Kantian Ideal with the reality of medical practice are considered. Each attempt is found to be unsuccessful. Accordingly, until a way is found to reconcile them, we conclude that the Kantian ideal is inconsistent with the reality of medical practice.

  4. The Statistical Mechanics of Ideal MHD Turbulence

    2003-01-01

    Turbulence is a universal, nonlinear phenomenon found in all energetic fluid and plasma motion. In particular. understanding magneto hydrodynamic (MHD) turbulence and incorporating its effects in the computation and prediction of the flow of ionized gases in space, for example, are great challenges that must be met if such computations and predictions are to be meaningful. Although a general solution to the "problem of turbulence" does not exist in closed form, numerical integrations allow us to explore the phase space of solutions for both ideal and dissipative flows. For homogeneous, incompressible turbulence, Fourier methods are appropriate, and phase space is defined by the Fourier coefficients of the physical fields. In the case of ideal MHD flows, a fairly robust statistical mechanics has been developed, in which the symmetry and ergodic properties of phase space is understood. A discussion of these properties will illuminate our principal discovery: Coherent structure and randomness co-exist in ideal MHD turbulence. For dissipative flows, as opposed to ideal flows, progress beyond the dimensional analysis of Kolmogorov has been difficult. Here, some possible future directions that draw on the ideal results will also be discussed. Our conclusion will be that while ideal turbulence is now well understood, real turbulence still presents great challenges.

    2014-12-01

    Full Text Available Using data from Eurobarometer Surveys 2001–2011 we examine trends and correlates of childlessness intentions and ideals across Europe over the past decade. We distinguish childlessness as a personal preference (personal ideal number of children is zero from intended childlessness (intention to have no children as these reflect somewhat different dimensions of childlessness as a conscious decision. We find that, on average, childlessness as a personal preference is relatively rare in Europe, although in some western European countries a sizeable proportion of young adults express a desire to have no children. Intentional childlessness is slightly more common than ideal childlessness is, since about 11% of currently childless young adults aged 18 to 40 years in Europe intend to have no children. We analyse factors related to childlessness intentions and ideals on the individual and country levels. A weaker individual socioeconomic position influences the intention to remain childless through various channels, such as unemployment or low socioeconomic status. Associations between individual’s social position and ideal childlessness are less clear. Results also indicate that macro-economic conditions do not have a direct impact on intentional childlessness, whereas a higher prevalence of traditional family values in a country is related to a lower likelihood of individuals considering childlessness to be their ideal family form.

The main element is an aim. The aim is an ideal image of the expecting result which is regarded as a guide for the educational activity of a certain ethnic community. The content of the notion of educational ideal is the imagery about the most important qualities of a personality, their manners, culture of relationship in the society, behavior. Ukrainian mentality is practicality, rationality, generosity, intellect in general. It is fully reflected in the pedagogical aim. At the same time mental means spiritual. That is something in thoughts and intents of a person. It is important to emphasize that Ukrainian ethos was formed on the basis of several groups, not only having formed a nation, but also having synthesized the temperament, traditions and customs, clothes and everyday life, culture in general. Hutsul, Boyko, Lemko (121 ethnic groups all together differ by the uniqueness of the appearance. At the same time their internal essence, that is educational ideal, world view, ethic morals, are unchangeable. Educational ideal is historically determined. Esthetic strategies, formation of creativity, development of the abilities by the means of folk crafts and trades, upbringing of a host pierce through the educational ideal of nowadays Ukrainians. The people aim to bring up their children as true citizens: good kids mean quiet old age, while with evil children old age becomes a hell. Thus, the educational ideal of the Ukrainians should be considered as a basis for modern educational technologies projection.

    Directory of Open Access Journals (Sweden)

    Cláudia de Paula Juliano Souza

    Full Text Available RESUMO O objetivo deste trabalho foi analisar o papel da psicoterapia de grupo na formação do residente em psiquiatria do Programa de Residência Médica em Psiquiatria da Universidade Federal de Goiás. Trata-se de um estudo descritivo exploratório com abordagem qualitativa em educação médica. Os dados foram coletados por meio de relatórios descritivos e entrevistas semiestruturadas, submetidas à análise de conteúdo temático-categorial. Emergiram da análise dos dados duas categorias: as ações educativas do ensino da psicoterapia de grupo e as ações sociais do ensino da psicoterapia de grupo. Na análise da primeira categoria, obtivemos cinco subcategorias: relação médico-paciente, aprendizagem cognitiva, aprendizagem afetiva, diálogo interdisciplinar e desenvolvimento pessoal. Na segunda categoria, obtivemos duas subcategorias: socialização e encontro. Conclui-se que o ensino da psicoterapia de grupo tem papel educativo, pois contribui com a inovação dos cenários de prática, possibilitando mudanças na relação médico residente-paciente e consolidando o conceito ampliado de saúde na perspectiva da integralidade. Revela também seu papel social, pois contribui para uma aproximação sociointerativa entre preceptor-residente-grupo.

  9. A hipotética linguagem ideal de Platão Plato's hypothetical ideal language

    Maria Carolina Alves dos Santos

    2003-01-01

    Full Text Available Para que um discurso sobre o espetáculo do mundo transcendente seja acolhido como totalidade inteligível e coerente, urge desvencilhar-se da arbitrariedade do domínio de trêmulos contornos do sensível, esfera de opiniões apenas. É o que propõe Platão, na esteira das reflexões dos primeiros pensadores: para suprir deficiências que causam a elisão da realidade e transformar a linguagem num veículo de intelecção autêntica dos conceitos essenciais de um pensar filosófico, ele a coloca no centro de uma especulação rigorosa. Tal como seus antecessores Heráclito e Parmênides, Platão revela logofilia ao empenhar-se na construção de uma nova estrutura discursiva, diferente daquela do homem comum, desencadeando no campo da Filosofia uma revolução que se tornara indispensável: elabora um modelo fundador - princípio de uma ordem permanente propedêutica à construção de uma linguagem formal e abstrata - referente a entes que os homens, na maioria, por si mesmos não conseguem visualizar. Somente nela poderá reverberar a verdade universal das Formas que, ao emprestarem seus nomes à infindável série dos particulares sensíveis, os clarifica e lhes confere significação. Com as teorias que a partir das Formas desenvolve e expõe nos Diálogos, o filósofo visa induzir o leitor a preparar-se para operar, metodicamente, a conversão de sua alma ao plano desses seres ideais, supra-sensíveis, e apreender, assim, a realidade que tudo fundamenta e torna cognoscível.For a discourse on the spectacle of the transcendental world to be received in its comprehensible and coherent totality, its needs to get rid of the arbitrariness of the dominion of tremulous shapes of the sensitive, which is merely the sphere of opinions. This is what Plato suggests, following the course of reflection of the first thinkers: in order to compensate the deficiencies that entail elision of reality and to transform language into a vehicle of authentic

    Full Text Available Most educators agree that problem solving is among the most meaningful and importantkinds of learning and thingking. That is, the central focus of learning and instructionshould be learning to solve problems. There are several warrants supporting that claims.They are authenticity, relevance, problem solving engages deeper learning angtherefore enhances meaning making, and constructed to represent problems (problemsolving is more meaningful. It is the reason why we must provide teaching and learningto make student’s problem solving skill in progress. There are many informationprocessingmodels of problem solving, such as simplified model of the problem-solvingprocess by Gicks, Polya’s problem solving process etc. One of them is IDEAL problemsolving.

  11. A temática da humanização na saúde: alguns apontamentos para debate

    Directory of Open Access Journals (Sweden)

    Waldir da Silva Souza

    Full Text Available A humanização na saúde é tematizada segundo uma digressão sociohistórica sobre as bases do humanismo no Ocidente e sua atual diluição em diversos setores da vida social; diluição esta qualificada com um tom positivo, essencialista, que contribui para que o humanismo seja identificado como um "bem sagrado" ou uma grife. Buscando problematizar esta questão, foram considerados os documentos produzidos pela Política Nacional de Humanização, confrontando o princípio constitucional da integralidade com a orientação da humanização. Nos documentos, a perspectiva da "produção da saúde" engloba: a atenção ou prestação do cuidado (práticas profissionais, a gestão dos processos de trabalho e a participação dos usuários ou controle social no interior dos processos de trabalho na saúde. Conclui-se que discutir humanização significa: rever idealizações que desconsideram os limites do humano, admitir o conflito como motor de negociações, e colocar em análise a forma como os grupos se organizam em seus processos de trabalho.

    Full Text Available In this paper we investigate graded compactly packed rings, which is defined as; if any graded ideal I of R is contained in the union of a family of graded prime ideals of R, then I is actually contained in one of the graded prime ideals of the family. We give some characterizations of graded compactly packed rings. Further, we examine this property on h – Spec(R. We also define a generalization of graded compactly packed rings, the graded coprimely packed rings. We show that R is a graded compactly packed ring if and only if R is a graded coprimely packed ring whenever R be a graded integral domain and h – dim R = 1.

    Mrowczynski, S.

    1983-01-01

    The properties of the ideal gas of classical (nonquantum) faster than light particles-tachyons have been considered. The basic notions of thermodynamics of tachyons have been introduced. We have found the partition function and other thermodynamical quantities for the ideal tachyon gas. The equation of state which we have found for tachyons is exactly the same as for the ideal gas of partictes slower than light-bradyons. The internal energy and the apecific heat have been discussed at low and at very high temperatures. It has been shown that in high temperature limit the properties of gas of tachyons and gas of bradyons are th'e same. The numerical calculations concerning the internal energy and specific heat at different temperatures were performed and the results have been presented. It has been shown that in full interval of temperature the characteristics of gas of tachyons are similar to those of gas of bradyons

  15. Analysis of an ideal amorphous solid

    International Nuclear Information System (INIS)

    To, L.T.; Stachurski, Z.H.

    2004-01-01

    Full text: In geometrical terms, amorphous solids are fundamentally different from crystalline solids in that they can not be constructed by the crystallographic method of translation of the basis along a lattice. Therefore, to study amorphous structures we must invoke concepts and use measures different to those used for ordered structures. Nevertheless, an ideal amorphous solid must share together with the ideal crystalline solid in the same definition of the term 'ideal'. In both cases it must be a perfect body, in which perfection is carried through in every detail to an unlimited (infinite) size without fault or defect. The latest results on this research will be presented. To qualify for a solid, rigid body, close packing of the spheres is required. For an ideal amorphous solids composed of hard spheres of identical size, we impose a stricter condition for the packing, namely, to be such that all spheres are in fixed positions (no loose spheres). To define the ideal solid, we must define what we mean by a perfect amorphous structure. Here, perfection is defined by, first the definition of imperfections, and next by the requirement of absence of imperfections of any kind. We envisage two types of defects: (i) geometrical, and (ii) statistical. Geometrical defects are: a sphere of different size, a loose sphere, and a vacancy. A statistical defect is defined with respect to two statistical functions: Ψ(N C ), and Φ(S β ). The former describes the probability of a given sphere having nc number of touching contacts, and the latter describes the disposition of the contacts on the surface of the sphere. Defects relating to the two functions will be described. The results for the functions, Ψ(N C ), and Φ(S β ), for the corresponding radial distribution function, and so called blocking number will be presented from simulations of an ideal amorphous solid

    In this book Professor Rees introduces and proves some of the main results of the asymptotic theory of ideals. The author's aim is to prove his Valuation Theorem, Strong Valuation Theorem, and Degree Formula, and to develop their consequences. The last part of the book is devoted to mixed multiplicities. Here the author develops his theory of general elements of ideals and gives a proof of a generalised degree formula. The reader is assumed to be familiar with basic commutative algebra, as covered in the standard texts, but the presentation is suitable for advanced graduate students. The work

  17. Ideal magnetohydrodynamic stability of axisymmetric mirrors

    International Nuclear Information System (INIS)

    D'Ippolito, D.A.; Hafizi, B.; Myra, J.R.

    1982-01-01

    The governing partial differential equation for general mode-number pressure-driven ballooning modes in a long-thin, axisymmetric plasma is derived within the context of ideal magnetohydrodynamics. It is shown that the equation reduces in special limits to the Hain--Luest equation, the high-m diffuse p(psi) ballooning equation, and the low-m sharp-boundary equation. A low-β analytic solution of the full partial differential equation is presented for quasiflute modes in an idealized tandem mirror model to elucidate the relationship of the various limiting cases

  18. At the Origin of Leonardo’s Ideal Man

    Directory of Open Access Journals (Sweden)

    Claudio Sgarbi

    2012-06-01

    Full Text Available After the discovery and the research developed in the last twenty years, it has been possible to announce, in 2010, a convincing attribution for the manuscript brought to the attention of the public as Vitruvio Ferrarese. The author is Giacomo Andrea da  Ferrara. Luca Pacioli defined him a great expert on Vitruvius and a very close friend of Leonardo da Vinci (“suo quanto fratello”. The discovery of the author was possible just because of the profound relationships between the drawings of Giacomo Andrea and Leonardo in the creation of the famous Vitruvian Man. The reconstructed phases of the drawing process show that the beginning of the formation of the images took place on the folios of the manuscript by Giacomo Andrea with an intense collaboration with Leonardo. Notwithstanding the creative team work, taking place between the two artists in Milan at the end of XV century, Giacomo and Leonardo ended up representing rather different ideal men. The tragic death of Giacomo Andrea in 1500 has obscured his role in the culture of the Renaissance.

  19. Mathematics and geometry towards ideality in «Domus»’s ideal houses

    Directory of Open Access Journals (Sweden)

    Simona Chiodo

    2018-01-01

    Full Text Available Between 1942 and 1943 the editor of the journal «Domus» invited the most important Italian architects to design their ideal houses: fifteen projects designed by seventeen architects were published. They are most instructive to try to understand, firstly, what the philosophical notion of ideal means and, secondly, why mathematical and geometric tools are extensively used to work on ideality, namely, to design ideal houses. The first part of the article focuses on the philosophical foundations of ideality and, after an overview of the fifteen projects, on the use of the golden ratio in two particularly meaningful cases. The second part of the article focuses on the cases in which there is a hidden use of the golden ratio, on the use of the modulus and on the use of the number 2.

    2018-01-01

    Full Text Available A new model is introduced in the process of evaluating efficiency value of decision making units (DMUs through data envelopment analysis (DEA method. Two virtual DMUs called ideal point DMU and anti-ideal point DMU are combined to form a comprehensive model based on the DEA method. The ideal point DMU is taking self-assessment system according to efficiency concept. The anti-ideal point DMU is taking other-assessment system according to fairness concept. The two distinctive ideal point models are introduced to the DEA method and combined through using variance ration. From the new model, a reasonable result can be obtained. Numerical examples are provided to illustrate the new constructed model and certify the rationality of the constructed model through relevant analysis with the traditional DEA model.

    Full Text Available O estudo objetiva caracterizar a configuração demográfica dos trabalhadores ligados à enfermagem de equipes do PSF de 3 municípios de São Paulo e analisar a percepção destes quanto ao perfil profissional necessário à atuação junto ao PSF. Utilizou-se como instrumento para coleta de dados a entrevista semi-estruturada. Para a sistematização inicial dos dados utilizou-se do software ETHNOGRAPH, e, posteriormente realizou-se análise temática. Os temas identificados na fala dos trabalhadores, apontam para um "perfil necessário" à atuação no PSF: há uma percepção de que os trabalhadores devem ser comunicativos, dedicados, envolvidos, solidários, carinhosos, ter bom relacionamento, disponibilidade e ajudar a população. O conjunto dos dados, embora aponte em alguns momentos para um perfil profissional que contemple uma prática de caráter assistencialista, ao mesmo tempo encaminha para uma reflexão acerca de uma nova configuração da prática assistencial alicerçada na humanização e integralidade da assistência, assim como na construção da cidadania.

  19. Regular shock refraction in planar ideal MHD

    International Nuclear Information System (INIS)

    Delmont, P; Keppens, R

    2010-01-01

    We study the classical problem of planar shock refraction at an oblique density discontinuity, separating two gases at rest, in planar ideal (magneto)hydrodynamics. In the hydrodynamical case, 3 signals arise and the interface becomes Richtmyer-Meshkov unstable due to vorticity deposition on the shocked contact. In the magnetohydrodynamical case, on the other hand, when the normal component of the magnetic field does not vanish, 5 signals will arise. The interface then typically remains stable, since the Rankine-Hugoniot jump conditions in ideal MHD do not allow for vorticity deposition on a contact discontinuity. We present an exact Riemann solver based solution strategy to describe the initial self similar refraction phase. Using grid-adaptive MHD simulations, we show that after reflection from the top wall, the interface remains stable.

    2005-04-08

    We report a molecular dynamics study of a simple model system that has the static properties of an ideal gas, yet exhibits nontrivial "glassy" dynamics behavior at high densities. The constituent molecules of this system are constructs of three infinitely thin hard rods of length L, rigidly joined at their midpoints. The crosses have random but fixed orientation. The static properties of this system are those of an ideal gas, and its collision frequency can be computed analytically. For number densities NL(3)/V>1, the single-particle diffusivity goes to zero. As the system is completely structureless, standard mode-coupling theory cannot describe the observed structural arrest. Nevertheless, the system exhibits many dynamical features that appear to be mode-coupling-like. All high-density incoherent intermediate scattering functions collapse onto master curves that depend only on the wave vector.

    2013-08-01

    Full Text Available The ideal-gas barometric and pressure laws are derived from the Democritian concept of independent corpuscles moving in vacuum, plus a principle of simplicity, namely that these laws are independent of the kinetic part of the Hamiltonian. A single corpuscle in contact with a heat bath in a cylinder and submitted to a constant force (weight is considered. The paper importantly supplements a previously published paper: First, the stability of ideal gases is established. Second, we show that when walls separate the cylinder into parts and are later removed, the entropy is unaffected. We obtain full agreement with Landsberg’s and others’ (1994 classical thermodynamic result for the entropy of a column of gas submitted to gravity.

    2011-01-01

    This report presents a summary of the work performed to meet FCR and D level 3 milestone M31SW050801, 'Complete the year-end report summarizing FY11 experimental and modeling activities.' This work was carried out under the auspices of the Non-Ideality in Solvent Extraction Systems FCR and D work package. The report summarizes our initial considerations of potential influences that non-ideal chemistry may impose on computational prediction of outcomes in solvent extraction systems. The report is packaged into three separate test cases where a robustness of the prediction by SXFIT program is under scrutiny. The computational exercises presented here emphasize the importance of accurate representation of both an aqueous and organic mixtures when modeling liquid-liquid distribution systems. Case No.1 demonstrates that non-ideal behavior of HDEHP in aliphatic diluents, such as n-dodecane, interferes with the computation. Cases No.2 and No.3 focus on the chemical complexity of aqueous electrolyte mixtures. Both exercises stress the need for an improved thermodynamic model of an aqueous environment present in the europium distribution experiments. Our efforts for year 2 of this project will focus on the improvements of aqueous and non-aqueous solution models using fundamental physical properties of mixtures acquired experimentally in our laboratories.

  10. Multi-axial response of idealized cermets

    International Nuclear Information System (INIS)

    Pickering, E.G.; Bele, E.; Deshpande, V.S.

    2016-01-01

    The yield response of two idealized cermets comprising mono and bi-disperse steel spheres in a Sn/Pb solder matrix has been investigated for a range of axisymmetric stress states. Proportional stress path experiments are reported, from which are extracted the initial yield surfaces and their evolution with increasing plastic strain. The initial yield strength is nearly independent of the hydrostatic pressure but the strain hardening rate increases with stress triaxiality up to a critical value. For higher triaxialities, the responses are independent of hydrostatic pressure. Multi-axial measurements along with X-ray tomography were used to demonstrate that the deformation of these idealized cermets occurs by two competing mechanisms: (i) a granular flow mechanism that operates at low levels of triaxiality, where volumetric dilation occurs under compressive stress states, and (ii) a plastically incompressible mechanism that operates at high stress triaxialities. A phenomenological viscoplastic constitutive model that incorporates both deformation mechanisms is presented. While such multi-axial measurements are difficult for commercial cermets with yield strengths on the order of a few GPa, the form of their constitutive relation is expected to be similar to that of the idealized cermets presented here.

  14. Medical ethics and more: ideal theories, non-ideal theories and conscientious objection.

    Luna, Florencia

    2015-01-01

    Doing 'good medical ethics' requires acknowledgment that it is often practised in non-ideal circumstances! In this article I present the distinction between ideal theory (IT) and non-ideal theory (NIT). I show how IT may not be the best solution to tackle problems in non-ideal contexts. I sketch a NIT framework as a useful tool for bioethics and medical ethics and explain how NITs can contribute to policy design in non-ideal circumstances. Different NITs can coexist and be evaluated vis-à-vis the IT. Additionally, I address what an individual doctor ought to do in this non-ideal context with the view that knowledge of NITs can facilitate the decision-making process. NITs help conceptualise problems faced in the context of non-compliance and scarcity in a better and more realistic way. Deciding which policy is optimal in such contexts may influence physicians' decisions regarding their patients. Thus, this analysis-usually identified only with policy making-may also be relevant to medical ethics. Finally, I recognise that this is merely a first step in an unexplored but fundamental theoretical area and that more work needs to be done. Published by the BMJ Publishing Group Limited.

    2012-01-01

    This study tested the direct effect of watching thin ideal children's television on body satisfaction in preadolescent girls (6-8 years old). A within-subject design was used in which girls (N = 51) were tested three times. They watched television clips in random order containing either (1) thin ideal animated characters or (2) animated characters with no thin ideal features or (3) 'real' human actors with no thin ideal features. After watching, their state body satisfaction was measured. Girls with higher levels of thin ideal internalisation showed higher body satisfaction after exposure to the thin ideal characters than after exposure to animated or real characters featuring no thin ideal features. No differences on body satisfaction between the exposure conditions were found in girls with lower levels of thin ideal internalisation. The results might suggest that young girls who internalised the thin ideal are inspired by thin ideal characters in children's media.

  18. Statistical Theory of the Ideal MHD Geodynamo

    Science.gov (United States)

    Shebalin, J. V.

    2012-01-01

    A statistical theory of geodynamo action is developed, using a mathematical model of the geodynamo as a rotating outer core containing an ideal (i.e., no dissipation), incompressible, turbulent, convecting magnetofluid. On the concentric inner and outer spherical bounding surfaces the normal components of the velocity, magnetic field, vorticity and electric current are zero, as is the temperature fluctuation. This allows the use of a set of Galerkin expansion functions that are common to both velocity and magnetic field, as well as vorticity, current and the temperature fluctuation. The resulting dynamical system, based on the Boussinesq form of the magnetohydrodynamic (MHD) equations, represents MHD turbulence in a spherical domain. These basic equations (minus the temperature equation) and boundary conditions have been used previously in numerical simulations of forced, decaying MHD turbulence inside a sphere [1,2]. Here, the ideal case is studied through statistical analysis and leads to a prediction that an ideal coherent structure will be found in the form of a large-scale quasistationary magnetic field that results from broken ergodicity, an effect that has been previously studied both analytically and numerically for homogeneous MHD turbulence [3,4]. The axial dipole component becomes prominent when there is a relatively large magnetic helicity (proportional to the global correlation of magnetic vector potential and magnetic field) and a stationary, nonzero cross helicity (proportional to the global correlation of velocity and magnetic field). The expected angle of the dipole moment vector with respect to the rotation axis is found to decrease to a minimum as the average cross helicity increases for a fixed value of magnetic helicity and then to increase again when average cross helicity approaches its maximum possible value. Only a relatively small value of cross helicity is needed to produce a dipole moment vector that is aligned at approx.10deg with the

  19. Dynamo Effects in Magnetized Ideal Plasma Cosmologies

    Kleidis, Kostas; Kuiroukidis, Apostolos; Papadopoulos, Demetrios; Vlahos, Loukas

    The excitation of cosmological perturbations in an anisotropic cosmological model and in the presence of a homogeneous magnetic field has been studied, using the ideal magnetohydrodynamic (MHD) equations. In this case, the system of partial differential equations which governs the evolution of the magnetized cosmological perturbations can be solved analytically. Our results verify that fast-magnetosonic modes propagating normal to the magnetic field, are excited. But, what is most important, is that, at late times, the magnetic-induction contrast (δB/B) grows, resulting in the enhancement of the ambient magnetic field. This process can be particularly favored by condensations, formed within the plasma fluid due to gravitational instabilities.

  1. Ideal quantum reading of optical memories

    2013-01-01

    Quantum reading is the art of exploiting the quantum properties of light to retrieve classical information stored in an optical memory with low energy and high accuracy. Focusing on the ideal scenario where noise and loss are negligible, we review previous works on the optimal strategies for minimal-error retrieving of information (ambiguous quantum reading) and perfect but probabilistic retrieving of information (unambiguous quantum reading). The optimal strategies largely overcome the optimal coherent protocols (reminiscent of common CD readers), further allowing for perfect discrimination. Experimental proposals for optical implementations of optimal quantum reading are provided.

    Fluid mechanics is examined from a Hamiltonian perspective. The Hamiltonian point of view provides a unifying framework; by understanding the Hamiltonian perspective, one knows in advance (within bounds) what answers to expect and what kinds of procedures can be performed. The material is organized into five lectures, on the following topics: rudiments of few-degree-of-freedom Hamiltonian systems illustrated by passive advection in two-dimensional fluids; functional differentiation, two action principles of mechanics, and the action principle and canonical Hamiltonian description of the ideal fluid; noncanonical Hamiltonian dynamics with examples; tutorial on Lie groups and algebras, reduction-realization, and Clebsch variables; and stability and Hamiltonian systems

    In this paper, the authors adapt to the ideal 1D lagrangian MHD equations a class of numerical schemes of order one in time and space presented in an earlier paper and applied to the gas dynamics system. They use some properties of systems of conservation laws with zero entropy flux which describe fluid models invariant by galilean transformation and reversible for regular solutions. These numerical schemes satisfy an entropy inequality under CFL conditions. In the last section, they describe a particular scheme for the MHD equations and show with some numerical applications its robustness and accuracy. The generalization to full Eulerian multidimensional MHD will be the subject of a forthcoming paper

    The ideal magnetohydrodynamic (MHD) stability of the National Compact Stellarator Experiment (NCSX) is extensively analyzed using the most advanced three-dimensional MHD codes. It is shown that the NCSX is stable to finite-n MHD modes, including the vertical mode, external kink modes and ballooning modes. However, high-n external kink modes that peak near the plasma edge are found to be weakly unstable. A global calculation shows that finite-n ballooning modes are significantly more stable than the local infinite-n modes

In the process of transformation of Ukrainian society towards the assimilation and implementation of basic European values such as human rights, democracy and the rule of law the role of personality that respects the dignity of others and their right to free expression in its multifaceted manifestations becomes more important. Such definitions of it assume the character of the ideal to be pursued, but that has not received adequate expression in people's minds and in practice yet. Since this ideal inextricably links right and personality, enabling the operation of law due to the special qualities of the individual, it can be defined as the ideal of legal personality. It is the formation and realization of such ideal that becomes urgent practical task of our society, which in turn requires a comprehensive theoretical understanding. Recent research and publications analysis. It should be noted that some philosophical aspects of the meaning of legal personality and its formation are revealed in the works of Ukrainian researcher in the field of philosophy of law S.I. Maksimov. However, all actual researches are based on a certain cultural and ideological tradition. The research of  a Polish-American scholar in the history of philosophical and legal thought Andrzej Walicki pays attention to the ideological and methodological potential liberal legal philosophy of the late 19th - early 20th century in the Russian Empire, realization of which, unfortunately, failed because of the violent interruption of this tradition by Bolsheviks. Researches of philosophers of law of that period are of particular significance in this issue: Ukrainian by origin and outlook Bohdan Kistyakivskiy and one of the authors of the Universal Declaration of Human Rights (1948 Serhiy Gessen. It is reconstruction of the concept of "legal personality" in the views of philosophers of law of that period, which is really made for the first time, which will give, as

Em 1991, a Famema passou a desenvolver o Projeto UNI, financiado pela Fundação Kellogg, iniciando um conjunto de mudanças no ensino de Medicina, resultando, em 1997, na introdução do método de ensino da Aprendizagem Baseada em Problemas (ABP. A ABP trabalha com a perspectiva holística do processo ensino aprendizagem e, por isso, estimula a participação ativa dos estudantes, principalmente, na cooperação em pequenos grupos; no auto-estudo e na educação multidisciplinar. Algum tempo após a introdução do ABP, identificou-se a dificuldade do uso de explicações das dimensões psicológicas e sociais para os problemas. A solução construída para a incorporação da dimensão social nos problemas foi a adoção da perspectiva sociológica das categorias fundantes da Saúde Coletiva: tempo, espaço e pessoa. O resultado foi a construção de uma matriz formada por seis tópicos e orientada para estimular os alunos a alcançar as noções de totalidade e integralidade do cuidado em saúde.

  9. Ideal relaxation of the Hopf fibration

    2017-07-01

    Ideal magnetohydrodynamics relaxation is the topology-conserving reconfiguration of a magnetic field into a lower energy state where the net force is zero. This is achieved by modeling the plasma as perfectly conducting viscous fluid. It is an important tool for investigating plasma equilibria and is often used to study the magnetic configurations in fusion devices and astrophysical plasmas. We study the equilibrium reached by a localized magnetic field through the topology conserving relaxation of a magnetic field based on the Hopf fibration in which magnetic field lines are closed circles that are all linked with one another. Magnetic fields with this topology have recently been shown to occur in non-ideal numerical simulations. Our results show that any localized field can only attain equilibrium if there is a finite external pressure, and that for such a field a Taylor state is unattainable. We find an equilibrium plasma configuration that is characterized by a lowered pressure in a toroidal region, with field lines lying on surfaces of constant pressure. Therefore, the field is in a Grad-Shafranov equilibrium. Localized helical magnetic fields are found when plasma is ejected from astrophysical bodies and subsequently relaxes against the background plasma, as well as on earth in plasmoids generated by, e.g., a Marshall gun. This work shows under which conditions an equilibrium can be reached and identifies a toroidal depression as the characteristic feature of such a configuration.

  11. A civil engineering approach to ideal MHD

    International Nuclear Information System (INIS)

    Jensen, V.O.

    1992-01-01

    It is well known that a magnetic field can be conceived as a medium where an isotropic compressive stress, B 2 /2μ 0 , is superimposed on a tensile stress, B 2 /μ 0 , parallel to the lines of force. When a stationary ideal MHD plasma is present in the magnetic field, the particle pressure adds to the magnetic stresses to form a combined stress tensor. Calculations of plasma equilibria based on this concept are very similar to calculations in civil engineering of static structures based on compressive, tensile, and shear stresses. Therefore the very simple physical pictures known from civil engineering when used in plasma physics provide simple physical understanding and facilitate the physical interpretation of the results. In an earlier paper the concept was used to derive and discuss the equilibrium equations for θ-, Z-, and screw pinches and the Grad-Shafranov shift in a tokamak plasma with circular cross sections of the flux surfaces. Here the concept is used to discuss the virial theorem and to obtain a simple physical interpretation of this theorem. We also reconsider the Grad-Shafranov shift in a tokamak plasma and show that a situation where all flux surfaces have circular cross sections cannot be an exact solution to the ideal MHD equations.

    This study explores the prerequisites of ideal safety-critical organizations, marshalling arguments of 4 areas of organizational research on safety, each of which has overlap: a safety culture, high reliability organizations (HROs), organizational resilience, and leadership especially in safety-critical organizations. The approach taken in this study was to retrieve questionnaire items or items on checklists of the 4 research areas and use them as materials of abduction (as referred to in the KJ method). The results showed that the prerequisites of ideal safety-oriented organizations consist of 9 factors as follows: (1) The organization provides resources and infrastructure to ensure safety. (2) The organization has a sharable vision. (3) Management attaches importance to safety. (4) Employees openly communicate issues and share wide-ranging information with each other. (5) Adjustments and improvements are made as the organization's situation changes. (6) Learning activities from mistakes and failures are performed. (7) Management creates a positive work environment and promotes good relations in the workplace. (8) Workers have good relations in the workplace. (9) Employees have all the necessary requirements to undertake their own functions, and act conservatively. (author)

  13. Nonlinear stability of ideal fluid equilibria

    International Nuclear Information System (INIS)

    Holm, D.D.

    1988-01-01

    The Lyapunov method for establishing stability is related to well- known energy principles for nondissipative dynamical systems. A development of the Lyapunov method for Hamiltonian systems due to Arnold establishes sufficient conditions for Lyapunov stability by using the energy plus other conserved quantities, together with second variations and convexity estimates. When treating the stability of ideal fluid dynamics within the Hamiltonian framework, a useful class of these conserved quantities consists of the Casimir functionals, which Poisson-commute with all functionals of the dynamical fluid variables. Such conserved quantities, when added to the energy, help to provide convexity estimates that bound the growth of perturbations. These convexity estimates, in turn, provide norms necessary for establishing Lyapunov stability under the nonlinear evolution. In contrast, the commonly used second variation or spectral stability arguments only prove linearized stability. As ideal fluid examples, in these lectures we discuss planar barotropic compressible fluid dynamics, the three-dimensional hydrostatic Boussinesq model, and a new set of shallow water equations with nonlinear dispersion due to Basdenkov, Morosov, and Pogutse[1985]. Remarkably, all three of these samples have the same Hamiltonian structure and, thus, possess the same Casimir functionals upon which their stability analyses are based. We also treat stability of modified quasigeostrophic flow, a problem whose Hamiltonian structure and Casimirs closely resemble Arnold's original example. Finally, we discuss some aspects of conditional stability and the applicability of Arnold's development of the Lyapunov technique. 100 refs

    we have today. This regulation created a new regulatory framework seen as promising at the time. However, now they recognize that, despite the good intentions, the NIJWP/85 has not solved any source disposition problems. The answer to these sealed source disposition problems is to adopt a philosophy to correct these regulatory issues, determine an interim solution, execute that solution until there is a minimal backlog of sources to deal with, and then let the mechanisms they have created solve this problem into the foreseeable future. The primary philosophical tenet of the ideal sealed source life cycle follows. You do not allow the creation (or importation) of any source whose use cannot be justified, which cannot be affordably shipped, or that does not have a well-delinated and affordable disposition pathway. The path forward dictates that we fix the problem by embracing the Ideal Source Life cycle. In figure 1, we can see some of the elements of the ideal source life cycle. The life cycle is broken down into four portions, manufacture, use, consolidation, and disposition. These four arbitrary elements allow them to focus on the ideal life cycle phases that every source should go through between manufacture and final disposition. As we examine the various phases of the sealed source life cycle, they pick specific examples and explore the adoption of the ideal life cycle model.

    Recently, El-Naschie has shown that the notion of fuzzy topology may be relevant to quantum paretical physics in connection with string theory and E-infinity space time theory. In this paper, we study the concepts of r-fuzzy semi-I-open, r-fuzzy pre-I-open, r-fuzzy α-I-open and r-fuzzy β-I-open sets, which is properly placed between r-fuzzy openness and r-fuzzy α-I-openness (r-fuzzy pre-I-openness) sets regardless the fuzzy ideal topological space in Sostak sense. Moreover, we give a decomposition of fuzzy continuity, fuzzy ideal continuity and fuzzy ideal α-continuity, and obtain several characterization and some properties of these functions. Also, we investigate their relationship with other types of function.

    Full Text Available The paper is devoted to the study of representations of the ideals and anti-ideals in secondary and high schools students. The study is important due to connection with the peculiarities of modern adolescent socialization in the context of contemporary social cultural realities. Shaping the world view in students is significantly influenced by the choice of values and the social role model. In this regard, the aim of this study was to examine gender and age dynamics of different groups of personalities related to the politics and spiritual culture in the structure of ideals and anti-idials in modern adolescents. Aggravation of the internal and external political situation, politically-oriented media content and society as a whole, the introduction of information technologies in various spheres of life, the «western» background of cultural values and information environment, the shift of sex-role identification has a significant influence on gender-specific and age-specific dynamics and significance of different groups of personalities in the structure of ideals and anti-idials in modern adolescents are based on the data of content analysis and a questionnaire survey of 2,273 students, grades 5-11. The features of the structure of ideals and anti-idials of boys and girls, which are formed under the influence of gender identification are characterized. The analysis of the students’ groups of ideals and anti-idials is held depending on their belonging to the Russian and foreign cultures. The students’ representations of the ideals and anti-idials are of a mixed structure, dominated by the personalities of the real people in comparison with the images (characters of works of literature, cinema, cartoons. The sphere of political culture and ideology (politicians, historical figures that presents male personalities is significant for boys. For girls, besides politics, the literary field (writers and movie actors is more important, where the

  20. Hereditary noetherian prime rings and idealizers

    CERN Document Server

    Levy, Lawrence S

    2011-01-01

    The direct sum behaviour of its projective modules is a fundamental property of any ring. Hereditary Noetherian prime rings are perhaps the only noncommutative Noetherian rings for which this direct sum behaviour (for both finitely and infinitely generated projective modules) is well-understood, yet highly nontrivial. This book surveys material previously available only in the research literature. It provides a re-worked and simplified account, with improved clarity, fresh insights and many original results about finite length modules, injective modules and projective modules. It culminates in the authors' surprisingly complete structure theorem for projective modules which involves two independent additive invariants: genus and Steinitz class. Several applications demonstrate its utility. The theory, extending the well-known module theory of commutative Dedekind domains and of hereditary orders, develops via a detailed study of simple modules. This relies upon the substantial account of idealizer subrings wh...

  1. Box of ideal gas in free fall

    We study the quantum partition function of non-relativistic, ideal gas in a (non-cubical) box falling freely in arbitrary curved spacetime with center 4-velocity u{sup a}. When perturbed energy eigenvalues are properly taken into account, we find that corrections to various thermodynamic quantities include a very specific, sub-dominant term which is independent of kinematic details such as box dimensions and mass of particles. This term is characterized by the dimensionless quantity, Ξ=R{sub 0{sup ^}0{sup ^}}Λ{sup 2}, where R{sub 0{sup ^}0{sup ^}}=R{sub ab}u{sup a}u{sup b} and Λ=βℏc, and, quite intriguingly, produces Euler relation of homogeneity two between entropy and energy – a relation familiar from black hole thermodynamics.

    2000-07-01

    A new method for the design of nonimaging devices is presented. Its application to the design of ultra flat compact concentrators is analysed. These new concentrators are based on a combination of two stages: the first one is composed of a large number of small structures placed side by side and the second one is a very compact single device concentrating the radiation to the limit. These devices are ideal for 2D. These compact designs are much more compact than the traditional ones like lens-mirror combinations or parabolic primaries with nonimaging secondaries. Besides, they can be designed for any acceptance angle, while the traditional ones are limited to small acceptance angles. (Author)

  3. Review of Idealized Aircraft Wake Vortex Models

    Science.gov (United States)

    Ahmad, Nashat N.; Proctor, Fred H.; Duparcmeur, Fanny M. Limon; Jacob, Don

    2014-01-01

    Properties of three aircraft wake vortex models, Lamb-Oseen, Burnham-Hallock, and Proctor are reviewed. These idealized models are often used to initialize the aircraft wake vortex pair in large eddy simulations and in wake encounter hazard models, as well as to define matched filters for processing lidar observations of aircraft wake vortices. Basic parameters for each vortex model, such as peak tangential velocity and circulation strength as a function of vortex core radius size, are examined. The models are also compared using different vortex characterizations, such as the vorticity magnitude. Results of Euler and large eddy simulations are presented. The application of vortex models in the postprocessing of lidar observations is discussed.

    The kinetic theory of non-relativistic positrons in an idealized positron emission tomography PET environment is developed by solving the Boltzmann equation, allowing for coherent and incoherent elastic, inelastic, ionizing and annihilating collisions through positronium formation. An analytic expression is obtained for the positronium formation rate, as a function of distance from a spherical source, in terms of the solutions of the general kinetic eigenvalue problem. Numerical estimates of the positron range - a fundamental limitation on the accuracy of PET, are given for positrons in a model of liquid water, a surrogate for human tissue. Comparisons are made with the ‘gas-phase’ assumption used in current models in which coherent scattering is suppressed. Our results show that this assumption leads to an error of the order of a factor of approximately 2, emphasizing the need to accurately account for the structure of the medium in PET simulations.

  5. Ideal MHD properties for proposed noncircular tokamaks

    Helton, F.J.; Greene, J.M.

    1986-01-01

    We obtain Double Dee, TFXC-C, Big Dee, and JET equlibria which are optimized with respect to both shape and current profile for stability to ideal MHD modes. With a wall reasonably far from the plasma surface we find that the external kink constrains q 1 to be above two, where q 1 is the plasma surface value of the safety factor, and the ballooning mode limits the value of β. Then a relevant stable β value for the Double Dee reactor design is over 7%. Such a Double Dee equilibrium is not in a separated second stability region and thus does not have a problem with accessibility. A relevant stable β value for the TFCX-C reactor design is over 6%. Equivalent relevant stable β values for the Big Dee (17%) and JET (7%) are included for calibration purposes. We compare these relevant stable β values with the β's determined by two recent scaling laws

    1995-01-01

    The concept of magnetic stresses in ideal MHD plasma theory is reviewed and revisited with the aim of demonstrating its advantages as a basis for calculating and understanding plasma equilibria. Expressions are derived for the various stresses that transmit forces in a magnetized plasma...... and it is shown that the resulting magnetic forces on a finite volume element can be obtained by integrating the magnetic stresses over the surface of the element. The concept is used to rederive and discuss the equilibrium conditions for axisymmetric toroidal plasmas, including the virial theorem...... and the Shafranov shift. The method had pedagogical merits as it simplifies the calculations, improves the physical understanding and facilitates an assessment of the approximations made in the calculations....

  7. How is the Ideal Gas Law Explanatory?

    Science.gov (United States)

    Woody, Andrea I.

    2013-07-01

    Using the ideal gas law as a comparative example, this essay reviews contemporary research in philosophy of science concerning scientific explanation. It outlines the inferential, causal, unification, and erotetic conceptions of explanation and discusses an alternative project, the functional perspective. In each case, the aim is to highlight insights from these investigations that are salient for pedagogical concerns. Perhaps most importantly, this essay argues that science teachers should be mindful of the normative and prescriptive components of explanatory discourse both in the classroom and in science more generally. Giving attention to this dimension of explanation not only will do justice to the nature of explanatory activity in science but also will support the development of robust reasoning skills in science students while helping them understand an important respect in which science is more than a straightforward collection of empirical facts, and consequently, science education involves more than simply learning them.

    Full Text Available Incorporation of active devices/media such as transistors for microwave and gain media for optics may be very attractive for enabling desired low loss and broadband metamaterials. Such metamaterials can even have gain which may very well lead to new and exciting physical phenomena. We investigate microwave composite right/left-handed transmission lines (CRLH-TL incorporating ideal gain devices such as constant negative resistance. With realistic lumped element values, we have shown that the negative phase constant of this kind of transmission lines is maintained (i.e., left-handedness kept while gain can be obtained (negative attenuation constant of transmission line simultaneously. Possible implementation and challenging issues of the proposed active CRLH-TL are also discussed.

  9. Definition and properties of ideal amorphous structures

    International Nuclear Information System (INIS)

    Stachurski, Z.H.

    2002-01-01

    Full text: Amorphous structure is usually defined by what it is not (ie, no crystalline peaks in XRS, no bond correlation in NMR), rather than by what it is. The interest in defining the structure of non-crystalline materials is long standing; packing geometry of spheres, molecular structure of glassy SiO 2 , or the structure of atactic polymers are prime examples. The earliest definitions of amorphous structure were in terms of a microcrystallite model of Valenkov, or continuous random network by Zachariasen. The random close packing of spheres of equal size, and an amorphous structure, composed of freely jointed linear chains of hard spheres, has been described mathematically in terms of a linear homogeneous Poisson process. This paper aims to describe some geometrical, kinematic, and topological properties of these two ideal amorphous structures, which belong to the same amorphous class. The geometry of packing is elucidated, and the use of Voronoi tessellation method for measuring the structures is described. The ideal amorphous solid has no symmetry elements; its volume can not be divided into identical unit cells. However, there is a volume element small enough to allow the distinction of its nanoscopic inhomogeneities, and sufficiently large enough to represent, accurately the overall behaviour. We define this volume element, the representative volume element. Suitable boundary conditions must be prescribed for a choice of RVE, and satisfy certain requirements. Topologically, a catchment region on the Born-Oppenheimer potential energy surface over nuclear configuration space, is defined by Mezey and Bader as an energetically stable geometry of the open region of R 3 traversed by all the trajectories which terminate at a local maximum. Two topological properties will be described: (i) the boundaries of the catchment region as a direct geometrical correspondence to the Voronoi polyhedron for a given atom in a given structure, and (ii) the constriction points

    To determine the parameters for an ideal smile. Ten laypersons classified frontal photographs of 62 smiling individuals between 18 and 25 years of age into five categories: 1, poor; 2, fair; 3, good; 4, very good; and 5, excellent. The scores obtained for each smile were averaged. The five smiles with each the highest and lowest scores were analyzed for seven parameters: buccal corridor, smile index, smile symmetry, smile line ratio, upper lip line, smile arc, and upper lip curvature. The five smiles with the highest scores were symmetrical with an average upper lip line and a consonant smile arc. Three of the five had an upward upper lip curvature. The smile line ratio, buccal corridor, and smile index for all five subjects ranged from 1.0 to 1.3 mm, 9.0% to 11.0%, and 4.0 to 6.0 mm, respectively. Two of the five smiles with the lowest scores were asymmetrical and three had a high upper lip line and a downward curvature, but all five had a nonconsonant smile arc. The smile line ratio, buccal corridor, and smile index for all five subjects ranged from -1.0 to 1.3 mm, 18.0% to 22.0%, and 7.0 to 10.0 mm, respectively. The seven investigated smile parameters can define characteristics of an ideal smile. These smile components should be included in the orthodontic problem list to help clinicians select the appropriate mechanotherapy. © 2010 BY QUINTESSENCE PUBLISHING CO, INC.

  14. From the ideal market to the ideal clinic: constructing a normative standard of fairness for human subjects research.

    Science.gov (United States)

    Phillips, Trisha

    2011-02-01

    Preventing exploitation in human subjects research requires a benchmark of fairness against which to judge the distribution of the benefits and burdens of a trial. This paper proposes the ideal market and its fair market price as a criterion of fairness. The ideal market approach is not new to discussions about exploitation, so this paper reviews Wertheimer's inchoate presentation of the ideal market as a principle of fairness, attempt of Emanuel and colleagues to apply the ideal market to human subjects research, and Ballantyne's criticisms of both the ideal market and the resulting benchmark of fairness. It argues that the criticism of this particular benchmark is on point, but the rejection of the ideal market is mistaken. After presenting a complete account of the ideal market, this paper proposes a new method for applying the ideal market to human subjects research and illustrates the proposal by considering a sample case.

    Full Text Available Este estudo teórico teve por objetivo identificar as propriedades dos gases reais que são eficazes para diferenciá-los dos gases ideais. Nesse trabalho, são abordadas e feitas comparações do comportamento dos gases reais por meio de diagramas e discussões teóricas por meio das quais se avalia o desvio de comportamento do gás real, com relação ao gás ideal, quando submetido a condições pré-definidas de temperatura e pressão. Analisou-se, também, o desempenho desses gases através das magnitudes dos seus fatores de compressibilidade. Observou-se que o aumento da pressão do gás provocou seu afastamento da idealidade enquanto que o aumento da temperatura o aproximou dela. A análise do fator de compressibilidade possibilitou identificar a aproximação entre o gás real e o ideal, quando esse parâmetro apresentou valores próximos da unidade. Palavras-chave: comportamento, gás real, gás ideal e fator de compressibilidade.

    We present a method for investigating the cyclicity of an elementary focus or center of a polynomial system of differential equations by means of complexification of the system and application of algorithms of computational algebra, showing an approach to treating the case that the Bautin ideal B of focus quantities is not a radical ideal (more precisely, when the ideal B is not radical, where B is the ideal generated by the shortest initial string of focus quantities that, like the Bautin ideal, determines the center variety). We illustrate the method with a family of cubic systems.

    This paper characterizes ideal structure of the uniform Roe algebra B* (X) over sinple cores X. A necessary and sufficient condition for a principal ideal of B*(X) to be spatial is given and an example of non-spatial ideal of B* (X) is constructed. By establishing an one-one correspondence between the ideals of B* (X) and the ω-filters on X, the maximal ideals of B* (X) are completely described by the corona of the Stone-Cech compactification of X.

    The ideal binary mask is often seen as a goal for time-frequency masking algorithms trying to increase speech intelligibility, but the required availability of the unmixed signals makes it difficult to calculate the ideal binary mask in any real-life applications. In this paper we derive the theory...... and the requirements to enable calculations of the ideal binary mask using a directional system without the availability of the unmixed signals. The proposed method has a low complexity and is verified using computer simulation in both ideal and non-ideal setups showing promising results....

  19. Ideal glass transitions by random pinning

    Cammarota, Chiara; Biroli, Giulio

    2012-01-01

    We study the effect of freezing the positions of a fraction c of particles from an equilibrium configuration of a supercooled liquid at a temperature T. We show that within the random first-order transition theory pinning particles leads to an ideal glass transition for a critical fraction c = cK(T) even for moderate supercooling; e.g., close to the Mode-Coupling transition temperature. First we derive the phase diagram in the T - c plane by mean field approximations. Then, by applying a real-space renormalization group method, we obtain the critical properties for |c - cK(T)| → 0, in particular the divergence of length and time scales, which are dominated by two zero-temperature fixed points. We also show that for c = cK(T) the typical distance between frozen particles is related to the static point-to-set length scale of the unconstrained liquid. We discuss what are the main differences when particles are frozen in other geometries and not from an equilibrium configuration. Finally, we explain why the glass transition induced by freezing particles provides a new and very promising avenue of research to probe the glassy state and ascertain, or disprove, the validity of the theories of the glass transition.

  20. Linear waves and stability in ideal magnetohydrodynamics

    International Nuclear Information System (INIS)

    Eckhoff, K.S.

    1987-05-01

    Linear waves superimposed on an arbitrary basic state in ideal magnetohydrodynamics are studied by an asymptotic expansion valid for short wavelenghts. The theory allows for a gravitational potential, and it may therefore be applied both in astrophysics and in problems related to thermonuclear fusion. The linearized equations for the perturbations of the basic state are found in the form of a symmetric hyperbolic system. This symmetric hyperbolic system is shown to possess characteristics of nonuniform multiplicity, which implies that waves of different types may interact. In particular it is shown that the mass waves, the Alf-n waves, and the slow magnetoacoustic waves will persistently interact in the exceptional case where the local wave number vector is perpendicular to the magnetic field. The equations describing this interaction are found in the form of a weakly coupled hyperbolic system. This weakly coupled hyperbloc system is studied in a number of special cases, and detailed analytic results are obtained for some such cases. The results show that the interaction of the waves may be one of the major causes of instability of the basic state. It seems beyond doubt that the interacting waves contain the physically relevant parts of the waves, which often are referred to as ballooning modes, including Suydam modes and Mercier modes

    Turnbull, A.D.; Chu, M.S.; Lao, L.L.; Greene, J.M.; Strait, E.J.; Chance, M.S.

    1991-01-01

    Continuum Alfven modes have undergone a resurgence in interest with the recent realization that so-called Toroidicity-Induced Alfven Eigenmodes (TAE modes) can be destabilized either by energetic beam ions in a strongly heated plasma or by alpha particles in a burning plasma. The GATO Ideal MHD Stability code, which minimizes the potential energy according to a variational formulation, has now been modified to isolate and calculate stable continuum eigenmodes. The existence of the TAE mode and its associated gap has been verified, using this code, for a circular cross-section, finite aspect ratio equilibrium. Moreover, the eigenfrequencies and eigenmodes obtained from this variational calculation are found to be in extremely good quantitative agreement with those obtained from the non-variational NOVA code. A systematic survey of the stable continuum has further revealed a surprising diversity in the structure of the continuum Alfven modes; the logarithmic singularity can be so broad, in some cases, as to occupy the whole cross-section. This has important implications for heating experiments which aim to locally excite the plasma by rf waves in the Alfven frequency range. The structure of several representative examples is discussed. The Alfven continuum, in general, and the TAE mode and its associated gap, in particular, are also found to be strongly modified by cross-sectional shaping. The dependence of the spectrum on various shaping factors is explored

  3. Axisymmetric ideal magnetohydrodynamic equilibria with incompressible flows

    International Nuclear Information System (INIS)

    Tasso, H.; Throumoulopoulos, G.N.

    1997-12-01

    It is shown that the ideal MHD equilibrium states of an axisymmetric plasma with incompressible flows are governed by an elliptic partial differential equation for the poloidal magnetic flux function ψ containing five surface quantities along with a relation for the pressure. Exact equilibria are constructed including those with non vanishing poloidal and toroidal flows and differentially varying radial electric fields. Unlike the case in cylindrical incompressible equilibria with isothermal magnetic surfaces which should have necessarily circular cross sections [G. N. Throumoulopoulos and H. Tasso, Phys. Plasmas 4, 1492 (1997)], no restriction appears on the shapes of the magnetic surfaces in the corresponding axisymmetric equilibria. The latter equilibria satisfy a set of six ordinary differential equations which for flows parallel to the magnetic field B can be solved semianalytically. In addition, it is proved the non existence of incompressible axisymmetric equilibria with (a) purely poloidal flows and (b) non-parallel flows with isothermal magnetic surfaces and vertical stroke B vertical stroke = vertical stroke B vertical stroke (ψ) (omnigenous equilibria).

  4. A full ranking for decision making units using ideal and anti-ideal points in DEA.

    Science.gov (United States)

    Barzegarinegad, A; Jahanshahloo, G; Rostamy-Malkhalifeh, M

    2014-01-01

    We propose a procedure for ranking decision making units in data envelopment analysis, based on ideal and anti-ideal points in the production possibility set. Moreover, a model has been introduced to compute the performance of a decision making unit for these two points through using common set of weights. One of the best privileges of this method is that we can make ranking for all decision making units by solving only three programs, and also solving these programs is not related to numbers of decision making units. One of the other advantages of this procedure is to rank all the extreme and nonextreme efficient decision making units. In other words, the suggested ranking method tends to seek a set of common weights for all units to make them fully ranked. Finally, it was applied for different sets holding real data, and then it can be compared with other procedures.

  5. Ideal thermodynamic processes of oscillatory-flow regenerative engines will go to ideal stirling cycle?

    Science.gov (United States)

    Luo, Ercang

    2012-06-01

    This paper analyzes the thermodynamic cycle of oscillating-flow regenerative machines. Unlike the classical analysis of thermodynamic textbooks, the assumptions for pistons' movement limitations are not needed and only ideal flowing and heat transfer should be maintained in our present analysis. Under such simple assumptions, the meso-scale thermodynamic cycles of each gas parcel in typical locations of a regenerator are analyzed. It is observed that the gas parcels in the regenerator undergo Lorentz cycle in different temperature levels, whereas the locus of all gas parcels inside the regenerator is the Ericson-like thermodynamic cycle. Based on this new finding, the author argued that ideal oscillating-flow machines without heat transfer and flowing losses is not the Stirling cycle. However, this new thermodynamic cycle can still achieve the same efficiency of the Carnot heat engine and can be considered a new reversible thermodynamic cycle under two constant-temperature heat sinks.

    Let R be a commutative Noetherian ring, and let N be a non-zero finitely generated R-module. The purpose of this paper is to show that if I and J are projectively equivalent ideals w.r.t. N, then a sequence x := x 1 , . . . , x n of elements of R is an asymptotic sequence over I w.r.t. N if and only if it is an asymptotic sequence over J w.r.t. N. Also, it is shown that if R is local, then the lengths of all maximal asymptotic sequences over an ideal I w.r.t. N are the same. As a consequence we derive a generalization of Rees' theorem.

  8. Family Life and Developmental Idealism in Yazd, Iran

    Directory of Open Access Journals (Sweden)

    Mohammad Jalal Abbasi-Shavazi

    2012-03-01

    Full Text Available BACKGROUND This paper is motivated by the theory that developmental idealism has been disseminated globally and has become an international force for family and demographic change. Developmental idealism is a set of cultural beliefs and values about development and how development relates to family and demographic behavior. It holds that modern societies are causal forces producing modern families, that modern families help to produce modern societies, and that modern family change is to be expected. OBJECTIVE We examine the extent to which developmental idealism has been disseminated in Iran. We also investigate predictors of the dissemination of developmental idealism. METHODS We use survey data collected in 2007 from a sample of women in Yazd, a city in Iran. We examine the distribution of developmental idealism in the sample and the multivariate predictors of developmental idealism. RESULTS We find considerable support for the expectation that many elements of developmental idealism have been widely disseminated. Statistically significant majorities associate development with particular family attributes, believe that development causes change in families, believe that fertility reductions and age-at-marriage increases help foster development, and perceive family trends in Iran headed toward modernity. As predicted, parental education, respondent education, and income affect adherence to developmental idealism. CONCLUSIONS Developmental idealism has been widely disseminated in Yazd, Iran and is related to social and demographic factors in predicted ways. COMMENTS Although our data come from only one city, we expect that developmental idealism has been widely distributed in Iran, with important implications for family and demographic behavior.

    Full Text Available Commemorating the 75-year existence of the journal Koers is connected to the Reformational tradition, from Calvin to Kuyper, Stoker, Dooyeweerd and Vollenhoven – all thinkers who realised that the biblical starting point of life indeed touches the heart, the religious root, of humankind and therefore cannot remain restricted to church life and religion in its narrow sense, but must come to expression in all walks of life. This awareness was a fruit of the Christian worldview and lifeview which currently is confronted by the Big Bang claims and by neo-Darwinism – both movements taking on cultic dimensions with an intolerance towards everyone who does not accept their perspective. Their attitude generated serious reactions on two websites, the impact of which was discussed in this article. Some problems entailed in Darwinism and physicalistic materialism were highlighted, before attention was given to the status of natural laws and normative principles. Particular attention was given to the elimination of God’s law and the way in which modern Humanism explored the two cornerstones of modern nominalism, up to the point where human understanding was elevated to become the a priori formal law-giver of nature. This legacy was continued both by the later developments within the Baden school of neo-Kantian thought and Postmodernism,which is placed within the context of the three succeeding epistemic ideals of the past three centuries. Rationality can only fulfil its true calling when it accounts for the cohering diversity within reality without becoming a victim of any form of reductionism – and by following this guiding star, Koers will continue to strengthen its invaluable contribution to the advancement of Christian scholarship.

  10. The ideal Bose-Einstein gas, revisited

    International Nuclear Information System (INIS)

    Ziff, R.M.; Uhlenbeck, G.E.; Kac, M.

    1977-01-01

    Some questions concerning the ideal Bose-Einstein gas are reviewed and examined further. The bulk behavior including the condensation phenomenon is characterized by the thermodynamical properties, occupations of the states and their fluctuations, and the properties of the density matrices, including the diagonal and off-diagonal long range orders. Particular attention is focused on the difference between the canonical and grand canonical ensembles and a case is made that the latter does not represent any physical system in the condensed region. The properties in a finite region are also examined to study the approach to the bulk limit and secondly to derive the surface properties such as the surface tension (due to the boundary). This is mainly done for the special case of a rectangular parallelopiped (box) for various boundary conditions. The question of the asymptotic behavior of the fluctuations in the occupation of the ground state in the condensed region in the canonical ensemble is examined for these systems. Finally, the local properties near the wall of a half infinite system are calculated and discussed. The surface properties also follow this way and agree with the strictly thermodynamic result. Although it is not intended to be a complete review, it is largely self-contained, with the first section containing the basic formulas and a discussion of some general concepts which will be needed. Especially discussed in detail are the extra considerations that are needed in thermodynamics and statistical mechanics to include the surface properties, and the quantum hierarchy of the density matrices and local conservation laws. In the concluding remarks several problems are mentioned which need further analysis and clarification. (Auth.)

  11. Hamiltonian description of the ideal fluid

    International Nuclear Information System (INIS)

    Morrison, P.J.

    1998-01-01

    The Hamiltonian viewpoint of fluid mechanical systems with few and infinite number of degrees of freedom is described. Rudimentary concepts of finite-degree-of-freedom Hamiltonian dynamics are reviewed, in the context of the passive advection of a scalar or tracer field by a fluid. The notions of integrability, invariant-tori, chaos, overlap criteria, and invariant-tori breakup are described in this context. Preparatory to the introduction of field theories, systems with an infinite number of degrees of freedom, elements of functional calculus and action principles of mechanics are reviewed. The action principle for the ideal compressible fluid is described in terms of Lagrangian or material variables. Hamiltonian systems in terms of noncanonical variables are presented, including several examples of Eulerian or inviscid fluid dynamics. Lie group theory sufficient for the treatment of reduction is reviewed. The reduction from Lagrangian to Eulerian variables is treated along with Clebsch variable decompositions. Stability in the canonical and noncanonical Hamiltonian contexts is described. Sufficient conditions for stability, such as Rayleigh-like criteria, are seen to be only sufficient in the general case because of the existence of negative-energy modes, which are possessed by interesting fluid equilibria. Linearly stable equilibria with negative energy modes are argued to be unstable when nonlinearity or dissipation is added. The energy-Casimir method is discussed and a variant of it that depends upon the notion of dynamical accessibility is described. The energy content of a perturbation about a general fluid equilibrium is calculated using three methods. copyright 1998 The American Physical Society

    The Stephani universes that can be interpreted as an ideal gas evolving in local thermal equilibrium are determined. Five classes of thermodynamic schemes are admissible, which give rise to five classes of regular models and three classes of singular models. No Stephani universes exist representing an exact solution to a classical ideal gas (one for which the internal energy is proportional to the temperature). But some Stephani universes may approximate a classical ideal gas at first order i...

    We consider a cylindrically symmetrical shock converging onto an axis within the framework of ideal, compressible-gas non-dissipative magnetohydrodynamics (MHD). In cylindrical polar co-ordinates we restrict attention to either constant axial magnetic field or to the azimuthal but singular magnetic field produced by a line current on the axis. Under the constraint of zero normal magnetic field and zero tangential fluid speed at the shock, a set of restricted shock-jump conditions are obtained as functions of the shock Mach number, defined as the ratio of the local shock speed to the unique magnetohydrodynamic wave speed ahead of the shock, and also of a parameter measuring the local strength of the magnetic field. For the line current case, two approaches are explored and the results compared in detail. The first is geometrical shock-dynamics where the restricted shock-jump conditions are applied directly to the equation on the characteristic entering the shock from behind. This gives an ordinary-differential equation for the shock Mach number as a function of radius which is integrated numerically to provide profiles of the shock implosion. Also, analytic, asymptotic results are obtained for the shock trajectory at small radius. The second approach is direct numerical solution of the radially symmetric MHD equations using a shock-capturing method. For the axial magnetic field case the shock implosion is of the Guderley power-law type with exponent that is not affected by the presence of a finite magnetic field. For the axial current case, however, the presence of a tangential magnetic field ahead of the shock with strength inversely proportional to radius introduces a length scale R=√(μ 0 /p 0 ) I/(2 π) where I is the current, μ 0 is the permeability, and p 0 is the pressure ahead of the shock. For shocks initiated at r ≫ R, shock convergence is first accompanied by shock strengthening as for the strictly gas-dynamic implosion. The diverging magnetic field

    Full Text Available Este trabalho discute as características da formação médica frente ao processo de envelhecimento e as especificidades da atenção à saúde do idoso, de forma a sistematizar as competências necessárias para profissionais de saúde. A premissa é que existe uma distância marcante entre, por um lado, conteúdos necessários à boa prática geriátrica e diretrizes das políticas de saúde e educação e, por outro lado, o currículo atual da graduação e da pós-graduação. A transição epidemiológica e demográfica coloca a Geriatria e Gerontologia como uma especialidade com mercado em expansão, tanto no setor público como privado, implicando a discussão da normatização da formação e distribuição de RH na saúde. Porém, a pouca valorização da presença de seus conteúdos nos currículos não reflete apenas uma questão pedagógica. Ao que tudo indica, apesar da legislação existente, ainda não está clara a importância destes conteúdos para a sociedade. A inclusão do processo de envelhecimento como curso de vida e em todos os seus aspectos nos currículos de graduação é uma prioridade. É também necessário ampliar a discussão sobre o papel da pós-graduação, da educação permanente e da educação continuada a fim de fazer frente ao desafio de envelhecer com qualidade.This paper discusses the challenges faced by medical education with regard to the aging Brazilian population as well as the specificities of senior health care services, aiming at systematizing the contents and practices needed to prepare health professionals.

    2014-03-01

    Full Text Available IDEAL is an efficient segregated algorithm for the fluid flow and heat transfer problems. This algorithm has now been extended to the 3D nonorthogonal curvilinear coordinates. Highly skewed grids in the nonorthogonal curvilinear coordinates can decrease the convergence rate and deteriorate the calculating stability. In this study, the feasibility of the IDEAL algorithm on highly skewed grid system is analyzed by investigating the lid-driven flow in the inclined cavity. It can be concluded that the IDEAL algorithm is more robust and more efficient than the traditional SIMPLER algorithm, especially for the highly skewed and fine grid system. For example, at θ = 5° and grid number = 70 × 70 × 70, the convergence rate of the IDEAL algorithm is 6.3 times faster than that of the SIMPLER algorithm, and the IDEAL algorithm can converge almost at any time step multiple.

  9. The role of the poet in Plato's ideal cities of Callipolis and Magnesia

    Full Text Available Plato's attitude toward the poets and poetry has always been a flashpoint of debate, controversy and notoriety, but most scholars have failed to see their central role in the ideal cities of the Republic and the Laws, that is, Callipolis and Magnesia. In this paper, I argue that in neither dialogue does Plato "exile" the poets, but, instead, believes they must, like all citizens, exercise the expertise proper to their profession, allowing them the right to become full-fledged participants in the productive class. Moreover, attention to certain details reveals that Plato harnesses both positive and negative factors in poetry to bring his ideal cities closer to a practical realization. The status of the poet and his craft in this context has rarely to my knowledge been addressed.A atitude de Platão com relação aos poetas e à poesia tem sempre sido um ponto de debate, controvérsia e notoriedade, mas a maioria dos estudiosos não consegue ver seu papel central nas cidades ideais da República e das Leis, ou seja, Callipolis e Magnésia. Neste artigo, defendo que em nenhum dos dois diálogos Platão exila os poetas, mas, ao contrário, acredita que eles devem, como todos os cidadãos, exercitar a competência própria à sua profissão, permitindo-lhes o direito de se tornarem participantes com todos os direitos da classe produtora. Principalmente, se prestarmos a atenção devida em certos detalhes, veremos que Platão controla tanto os fatores positivos, como os negativos na poesia, para aproximar mais suas cidades ideais da realização prática. A meu ver, o estatuto do poeta e de sua habilidade, nesse contexto, foram raramente estudados.

The remanence distribution of this magnet is derived...... and the generated field is compared to that of a Halbach cylinder of equal dimensions. The ideal remanence magnet is shown in most cases to generate a significantly lower field than the equivalent Halbach cylinder, although the field is generated with higher efficiency. The most efficient Halbach cylinder is shown...... to generate a field exactly twice as large as the equivalent ideal remanence magnet....

    Idealization is an intrapsychic process that serves many functions. In addition to its use defensively and for gratification of libidinal and aggressive drive derivatives, it can contribute to developmental progression, particularly during late adolescence and young adulthood. During an analysis, it is important to recognize all the determinants of idealization, including those related to the reworking of developmental conflicts. If an analyst understands idealization solely as a manifestation of pathology, he may interfere with his patient's use of it for the development of autonomous functioning.

    Full Text Available O processo de integração econômica na América Latina antecedeu a própria integração da Comunidade Europeia, concretizadas por meio das ações de Simon Bolívar, um idealista revolucionário que contribuiu de forma decisiva com o processo de independência de vários paí¬ses latino-americanos no século XIX, promovendo a integração econômica e cultural da América Latina. Nesse sentido, evidencia-se que Simón Bolívar, cujo sonho era recuperar a unidade latino-americana, lutou para realizar o primeiro tratado da união latino-americana, que foi o Tratado de União, que estabelecia a Liga e Confederação Perpétua entre as Repúblicas da Colômbia, Peru, América Central e o México e pela organização da Grã-Colômbia unindo Colômbia, Peru, Venezuela e Equador. Foi eleito presidente da Grã-Colômbia, mas com a destruição de seu ideal de união, renunciou ao poder. No início do século XX ocorreram tentativas no sentido de formar uma integração dos três países mais expressivos da América do Sul (Argentina, Brasil e Chile, denominando-se essa tentativa de Bloco ABC. A partir de 1985, Brasil e Argentina assumem uma série de compromissos no sentido de viabilizar uma maior cooperação e integração econômica e por intermédio da Ata de Iguaçu, se materializa a primeira ação efetiva no alcance desses resultados. Por este instrumento os presidentes Sarney e Alfonsín criam uma Comissão Mista de Alto Nível para a Cooperação e Integração Econômica Bilateral, abrindo a possibilidade de associação do Uruguai. Em 1990 os Presidentes do Brasil e da Argentina, na Ata de Buenos Aires, resolvem institucionalizar o Mercado Comum e em 26 de março de 1991 é celebrado o Tratado de Assunção, entrando em vigor em 29 de novembro do mesmo ano, com o depósito das ratificações necessárias e fazendo parte desta integração a Argentina, o Brasil, o Paraguai e Uruguai.

  1. Ideal Based Cyber Security Technical Metrics for Control Systems

    Energy Technology Data Exchange (ETDEWEB)

    W. F. Boyer; M. A. McQueen

    2007-10-01

    Much of the world's critical infrastructure is at risk from attack through electronic networks connected to control systems. Security metrics are important because they provide the basis for management decisions that affect the protection of the infrastructure. A cyber security technical metric is the security relevant output from an explicit mathematical model that makes use of objective measurements of a technical object. A specific set of technical security metrics are proposed for use by the operators of control systems. Our proposed metrics are based on seven security ideals associated with seven corresponding abstract dimensions of security. We have defined at least one metric for each of the seven ideals. Each metric is a measure of how nearly the associated ideal has been achieved. These seven ideals provide a useful structure for further metrics development. A case study shows how the proposed metrics can be applied to an operational control system.

    Let R be a ring with unity and I(R)* be the set of all non-trivial left ideals of R. The intersection graph of ideals of R, denoted by G(R), is a graph with the vertex set I(R)* and two distinct vertices I and J are adjacent if and only if I intersection J ≠ 0. In this paper, we study some connections between the graph-theoretic properties of this graph and some algebraic properties of rings. We characterize all rings whose intersection graphs of ideals are not connected. Also we determine all rings whose clique number of the intersection graphs of ideals are finite. Among other results, it is shown that for every ring, if the clique number of G(R) is finite, then the chromatic number is finite too and if R is a reduced ring both are equal. (author)

    1993-04-01

    A numerical study of the free-boundary axisymmetric (n=0) ideal magnetohydrodynamical (MHD) motions of the Extrap device is presented. The dependence of stability on current profiles in the plasma and currents in the external conductors is investigated. Results are shown for linear growth-rates and nonlinear saturation amplitudes and their dependence on plasma radius as well as on the conducting shell radius. A method combined of two different algorithms has been developed and tested. The interior region of the plasma is simulated by means of a Lagrangian Finite Element Method (FEM) for ideal magnetohydrodynamics, The method is based on a nonlinear radiation principle for the Lagrangian description of ideal MHD. The Boundary Element Method (BEM) is used together with the Lagrangian FEM to simulate nonlinear motion of an ideal MHD plasma behaviour in a vacuum region under the influence of external magnetic fields. 31 refs

    2008-01-01

    The Department of Homeland Security National Cyber Security Division supported development of a small set of security ideals as a framework to establish measurable control systems security. Based on these ideals, a draft set of proposed technical metrics was developed to allow control systems owner-operators to track improvements or degradations in their individual control systems security posture. The technical metrics development effort included review and evaluation of over thirty metrics-related documents. On the bases of complexity, ambiguity, or misleading and distorting effects the metrics identified during the reviews were determined to be weaker than necessary to aid defense against the myriad threats posed by cyber-terrorism to human safety, as well as to economic prosperity. Using the results of our metrics review and the set of security ideals as a starting point for metrics development, we identified thirteen potential technical metrics - with at least one metric supporting each ideal. Two case study applications of the ideals and thirteen metrics to control systems were then performed to establish potential difficulties in applying both the ideals and the metrics. The case studies resulted in no changes to the ideals, and only a few deletions and refinements to the thirteen potential metrics. This led to a final proposed set of ten core technical metrics. To further validate the security ideals, the modifications made to the original thirteen potential metrics, and the final proposed set of ten core metrics, seven separate control systems security assessments performed over the past three years were reviewed for findings and recommended mitigations. These findings and mitigations were then mapped to the security ideals and metrics to assess gaps in their coverage. The mappings indicated that there are no gaps in the security ideals and that the ten core technical metrics provide significant coverage of standard security issues with 87% coverage. Based

    When a charged particle passes through an ideal crystal, then besides the transition radiation, a new kind of radiation, connected with the periodic structure of the crystal is produced. The influence of mosaic structure of a crystal on the intensity of this radiation is considered. Simple analytical expressions for the integral intensity of this radiation for the case of an ideal crystal are obtained. The results show, that the integral radiation intensity depends weakly on the degree of crystal perfection

    In a laboratory, a two-dimensional complex (dusty) plasma consists of a low-density ionized gas containing a confined suspension of Yukawa-coupled plastic microspheres. For an initial crystal-like form, we report ideal gas behavior in this strongly coupled system during shock-wave experiments. This evidence supports the use of the ideal gas law as the equation of state for soft crystals such as those formed by dusty plasmas.

    This study was designed to determine the effects of media-portrayed idealized images on young women's body shame and appearance anxiety, and to establish whether the effects depend on advertisement type and on participant self-objectification. Participants were 39 female university students. Twenty-four magazine advertisements comprised 12 body-related and 12 non-body-related products, one half of each with, and the other one half without, idealized images. Preexposure and post exposure body shame and appearance anxiety measures were recorded. Appearance anxiety increased after viewing advertisements featuring idealized images. There was also a significant interaction between self-objectification level and idealized body (presence vs. absence). No differences emerged for body-related compared with non-body-related product advertisements. The only result for body shame was a main effect for time. Participants' body shame increased after exposure to idealized images, irrespective of advertisement type. Although our findings reveal that media-portrayed idealized images detrimentally affect the body image of young women, they highlight the individual differences in vulnerability and the different effects for different components of body image. These results are discussed in terms of their implications for the prevention and early intervention of body image and dieting-related disorders. ( Copyright 2005 by Wiley Periodicals, Inc

    Full Text Available In Search of Ideal Form-Ratio of Triangular Channel. Cross-sectional form of a natural channel is a two dimensional variable which is thoroughly studied by scholars from different fields on natural sciences like hydrology, geology, geomorphology, etc. Average river channels tend to develop their channel-cross sectional form in a way to produce an approximate equilibrium between the channel and the water and sediment it transport. But how far it is deviated from the ideal cross-sectional form can only be determined by knowing the ideal form which was calculated by Hickin for rectangular channel. This ideal cross-sectional form of ‘maximum efficiency’ is virtually a theoretical one and attaining of which the river transports its water and load with least friction with its bed. ‘Ideal form ratio’ provides numerical tools for triangular channel to determine the degree of deviation of a cross-sectional form from that of an ideal one.

    In this paper, we examined the relationship between culture-specific ideals (chastity, masculinity, caste beliefs) and self-esteem, shame and depression using an idealized cultural model proposed by Mahalingam (2006, In: Mahalingam R (ed) Cultural psychology of immigrants. Lawrence Erlbaum, Mahwah, NJ, pp 1-14). Participants were from communities with a history of extreme male-biased sex ratios in Tamilnadu, India (N = 785). We hypothesized a dual-process model of self-appraisals suggesting that achieving idealized cultural identities would increase both self-esteem and shame, with the latter leading to depression, even after controlling for key covariates. We tested this using structural equation modeling. The proposed idealized cultural identities model had an excellent fit (CFI = 0.99); the effect of idealized identities on self-esteem, shame and depression differed by gender. Idealized beliefs about gender relate to psychological well-being in gender specific ways in extreme son preference communities. We discuss implications of these findings for future research and community-based interventions.

Labeling may have a poor impact on the counselor’s decision in selecting counseling intervention strategies. The multicultural insights of counselors must be enhanced by building an ideal character in themselves. This ideal character is concerned with the understanding and behavior of counselors to respond the condition of heterogeneous counselees and how high the curiosity, interest and motivation of counselors to constantly add multicultural insights that they have. The noble values contained within Semar can be attributed to how the ideal character of multicultural counselors. This study aims to explain the ideal character of multicultural counselor taken from the noble value of Semar as well as linking the character with multicultural competence of counselor. This research uses qualitative approach of library research type.

    Full Text Available We examined whether the relations of consistency between ideal standards and perceptions of a current romantic partner with partner acceptance and relationship satisfaction level off, or decelerate, above a threshold. We tested our hypothesis using a 3-year longitudinal data set collected from heterosexual newlywed couples. We used two indicators of consistency: pattern correspondence (within-person correlation between ideal standards and perceived partner ratings and mean-level match (difference between ideal standards score and perceived partner score. Our results revealed that pattern correspondence had no relation with partner acceptance, but a positive linear/exponential association with relationship satisfaction. Mean-level match had a significant positive association with actor’s acceptance and relationship satisfaction up to the point where perceived partner score equaled ideal standards score. Partner effects did not show a consistent pattern. The results suggest that the consistency between ideal standards and perceived partner attributes has a non-linear association with acceptance and relationship satisfaction, although the results were more conclusive for mean-level match.

Argumenta-se que há uma forma de conceber o ideal democrático - a "democracia deliberativa" - que resolve esse paradoxo da "democracia populista" sem negar, como faz o "liberalismo negativo", o valor do autogoverno na esfera da política. Mesmo o ideal de democracia deliberativa, entretanto, não tem como escapar da desarmonia entre a autodeterminação na política e a autodeterminação individual.The popular will may give support to political results that contradict the very conditions for popular rule. It is argued that the democratic ideal may be conceived - as a "deliberative democracy" - in such a way as to solve this paradox without deying , as negative liberalism does, the value of self-government in politics. Even for the ideal of deliberative democracy, however, the disharmony between autonomy in politics and individual autonomy is inescapable.

Written responses were collected from 547 self-identified gay men in the U.S. via an Internet-based survey. Findings supported previous reports that perceptions of gender roles among gay men appear based on masculine and feminine stereotypes. Additionally, more adverse versus positive effects on self-image and same-sex romantic relationships were reported including difficulty being emotional and affectionate, pressure to be physically attractive, and pressure to appear masculine in order to be accepted by society and to be seen as desirable by other gay men. While research on gay men's experience with masculinity continues, psychologists should consider the possible influence of traditional masculine ideals when conceptualizing their gay male clients.

    Full Text Available The present study aimed to test predictions based on both the ‗similarity-attraction‘ hypothesis and the ‗attraction-similarity‘ hypothesis, by studying perceptions of ideal and former partners. Based on the ‗similarity-attraction‘ hypothesis, we expected individuals to desire ideal partners who are similar to the self in personality. In addition, based on the ‗attraction-similarity hypothesis‘, we expected individuals to perceive former partners as dissimilar to them in terms of personality. Findings showed that, whereas the ideal partner was seen as similar to and more positive than the self, the former partner was seen as dissimilar to and more negative than the self. In addition, our study showed that individuals did not rate similarity in personality as very important when seeking a mate. Our findings may help understand why so many relationships end in divorce due to mismatches in personality.

  14. The positive-entropy constraint for the classical ideal gas

    International Nuclear Information System (INIS)

    Ciccariello, Salvino

    2004-01-01

    The problem of determining the state parameters' sub-domain where the behaviour of the classical ideal gas approximates that of the Bose and Fermi ideal gases is tutorially discussed. The entropy of any quantum system being always positive, the classical approximation can only be satisfactory within the parameters' sub-domain where the classical entropy turns out to be positive. We show that the sub-domain determined by this condition is close to that where de Broglie's thermal wavelength is smaller than the mean interparticle distance. The exact determination of the state parameters' region, where the particle number density, the grand potential and the entropy of quantum ideal gases differ from those of the classical gas less than a specified quantity, is also illustrated

  15. Saturated ideal modes in advanced tokamak regimes in MAST

    MAST plasmas with a safety factor above unity and a profile with either weakly reversed shear or broad low-shear regions, regularly exhibit long-lived saturated ideal magnetohydrodynamic (MHD) instabilities. The toroidal rotation is flattened in the presence of such perturbations and the fast ion losses are enhanced. These ideal modes, distinguished as such by the notable lack of islands or signs of reconnection, are driven unstable as the safety factor approaches unity. This could be of significance for advanced scenarios, or hybrid scenarios which aim to keep the safety factor just above rational surfaces associated with deleterious resistive MHD instabilities, especially in spherical tokamaks which are more susceptible to such ideal internal modes. The role of rotation, fast ions and ion diamagnetic effects in determining the marginal mode stability is discussed, as well as the role of instabilities with higher toroidal mode numbers as the safety factor evolves to lower values.

  16. Thermodynamics of an ideal generalized gas: I. Thermodynamic laws.

    Science.gov (United States)

    Lavenda, B H

    2005-11-01

    The equations of state for an ideal relativistic, or generalized, gas, like an ideal quantum gas, are expressed in terms of power laws of the temperature. In contrast to an ideal classical gas, the internal energy is a function of volume at constant temperature, implying that the ideal generalized gas will show either attractive or repulsive interactions. This is a necessary condition in order that the third law be obeyed and for matter to have an electromagnetic origin. The transition from an ideal generalized to a classical gas occurs when the two independent solutions of the subsidiary equation to Lagrange's equation coalesce. The equation of state relating the pressure to the internal energy encompasses the full range of cosmological scenarios, from the radiation to the matter dominated universes and finally to the vacuum energy, enabling the coefficient of proportionality, analogous to the Grüeisen ratio, to be interpreted in terms of the degrees of freedom related to the temperature exponents of the internal energy and the absolute temperature expressed in terms of a power of the empirical temperature. The limit where these exponents merge is shown to be the ideal classical gas limit. A corollary to Carnot's theorem is proved, asserting that the ratio of the work done over a cycle to the heat absorbed to increase the temperature at constant volume is the same for all bodies at the same volume. As power means, the energy and entropy are incomparable, and a new adiabatic potential is introduced by showing that the volume raised to a characteristic exponent is also the integrating factor for the quantity of heat so that the second law can be based on the property that power means are monotonically increasing functions of their order. The vanishing of the chemical potential in extensive systems implies that energy cannot be transported without matter and is equivalent to the condition that Clapeyron's equation be satisfied.

  17. Students’ Perception on Ideal Age of Marriage and Childbearing

    2015-12-01

    Full Text Available Background: Early-age marriage is still common in Indonesia, especially in the rural areas. There are many negative effects of the marriage; the young brides may get lower education, lower social status, minimum reproduction control, higher maternal mortality, higher domestic violence rate and others. Thus, this study is conducted to identify the students’ perception on the ideal age of marriage and childbearing. Methods: A cross-sectional descriptive study was conducted from June to September 2013 in Jatinangor using secondary data from Jatinangor Cohort Survey Team. The data comprised two hundred and twenty students from Jatinangor Senior High School and PGRI Vocational School. A hundred and ten males and a hundred and ten females were chosen by random sampling. Questionnaires were given after the written informed consent was obtained from the students. Results: The results showed 74.55% of the students chose 19¬–24 years old as the ideal age of marriage for a woman and 68.64% students chose 25–30 years old as the ideal age of marriage for a man. Moreover, for childbearing, 25–30 years old was chosen to be the ideal age for both man and woman. The percentage of students agreed to this was 74.55% and 54.09% respectively. Conclusions: Majority of the students agreed on 19–24 years old and 25–30 years old as the ideal age of marriage for woman and man respectively. For childbearing, 25–30 years old was concluded as the ideal age for both genders.

    1998-11-01

    Full Text Available When approaching electronic capital market design and microstructure with the focus of analysing and improving existing markets with end-state analysis, it is necessary to name an ideal objective. This serves the purposes of technology evaluation and the development of a standard framework for structural measurement in modeling and language paradigm design. An ideal capital market architecture is presented in this paper that is feasible with current technology based on the end-to-end functionality of existing capital markets including internal requirements of participants. Various architectural and ethical issues are introduced and discussed sketching a framework for further work in quantifying electronic markets.

    1996-10-01

    A construction principle for ideal nonimaging concentrators based on the complementary edge rays outside the nominal field of view is presented, with illustrations for the trumpet, compound parabolic concentrator, and compound hyperbolic concentrator. A simple string construction for the trumpet concentrator is shown to follow from this observation-the trumpet having been the one ideal concentrator for which no string-construction method had previously been noted. An application of these observations for solar concentrator design when nonisothermal receivers are advantageous is also presented.

  1. '' Ideal Gas '' gluon plasma with medium dependent dispersion relation

    International Nuclear Information System (INIS)

    Gorenstein, M.I.

    1995-01-01

    An '' ideal gas '' model with temperature dependent particle mass is constructed for the gluon plasma equation of state. This simple model gives us an example of a system with temperature dependent effective Hamiltonian. To satisfy thermodynamical relations in these systems, standard statistical mechanics formulas have to be supplemented by special requirements which are considered in details. A self-consistent '' ideal gas '' formulation is used to describe Monte Carlo lattice data for the thermodynamical functions of SU(2) and SU(3) gluon plasma. 14 refs., 8 figs

We show thatif $(e_{\\alpha}_{\\alpha}$ is a bounded approximate identity modulo $I$ of a Banach algebra $A$ and $X$ is a neo-unital modulo $I$, then $(e_{\\alpha}_{\\alpha}$ is a bounded approximate identity for $X$. Moreover we show that amenability modulo an ideal of a Banach algebra $A$ can be only considered by the neo-unital modulo $I$ Banach algebra over $A$

    1984-12-01

    The ideal Bose gas solved in the redefined ensemble formalism exhibits a discontinuity in the specific heat suggesting that Bose-Einstein condensation is a second order phase transition. The deviations from the classical ideal gas behaviour are larger than those predicted by Gibbs ensemble. Below Tsub(c) the pressure is not independent of the volume. For a certain range of values of VT 3 , the peak in black body radiation shows a shift in the frequency scale and this could be detected, at least in principle, experimentally. (author)

  4. Towards an ideal preconditioner for linearized Navier-Stokes problems

    Energy Technology Data Exchange (ETDEWEB)

    Murphy, M.F. [Univ. of Bristol (United Kingdom)

    1996-12-31

    Discretizing certain linearizations of the steady-state Navier-Stokes equations gives rise to nonsymmetric linear systems with indefinite symmetric part. We show that for such systems there exists a block diagonal preconditioner which gives convergence in three GMRES steps, independent of the mesh size and viscosity parameter (Reynolds number). While this {open_quotes}ideal{close_quotes} preconditioner is too expensive to be used in practice, it provides a useful insight into the problem. We then consider various approximations to the ideal preconditioner, and describe the eigenvalues of the preconditioned systems. Finally, we compare these preconditioners numerically, and present our conclusions.

    Full Text Available Resumo O objetivo deste artigo é avaliar a extensão dos atributos da APS, desde a experiência dos usuários, tanto adultos quanto cuidadores de crianças, comparando a área atendida pelas unidades de saúde do bairro da Rocinha com as demais áreas do distrito sanitário 2.1, no município do Rio de Janeiro. O instrumento de medida utilizado para avaliar a qualidade dos serviços prestados foi o Primary Care Assement Tool. Foi realizado estudo transversal, com amostras aleatórias independentes, com 802 entrevistados. Os resultados apontam melhor desempenho para o cuidado das crianças, quando comparado aos adultos. Os atributos “acesso” e “integralidade – serviços disponíveis” foram aqueles que tiveram os piores desempenhos, provavelmente devido a grande migração externa e interna existente dentro da própria Rocinha. Para melhoria desses atributos, recomendamos a adoção de uma lista única de moradores por ESF, com um número máximo de pessoas, contemplando além da delimitação territorial, a mobilidade interna das pessoas. Destacamos também a importância do fortalecimento do Programa de Residência em Medicina de Família e Comunidade, que desde 2012 forma especialistas, com apoio de preceptores, e viabiliza a ampliação da oferta da carteira de serviços de APS.

    Marinacci, Federico; Vogelsberger, Mark; Kannan, Rahul; Mocz, Philip; Pakmor, Rüdiger; Springel, Volker

    2018-05-01

    In certain astrophysical systems, the commonly employed ideal magnetohydrodynamics (MHD) approximation breaks down. Here, we introduce novel explicit and implicit numerical schemes of ohmic resistivity terms in the moving-mesh code AREPO. We include these non-ideal terms for two MHD techniques: the Powell 8-wave formalism and a constrained transport scheme, which evolves the cell-centred magnetic vector potential. We test our implementation against problems of increasing complexity, such as one- and two-dimensional diffusion problems, and the evolution of progressive and stationary Alfvén waves. On these test problems, our implementation recovers the analytic solutions to second-order accuracy. As first applications, we investigate the tearing instability in magnetized plasmas and the gravitational collapse of a rotating magnetized gas cloud. In both systems, resistivity plays a key role. In the former case, it allows for the development of the tearing instability through reconnection of the magnetic field lines. In the latter, the adopted (constant) value of ohmic resistivity has an impact on both the gas distribution around the emerging protostar and the mass loading of magnetically driven outflows. Our new non-ideal MHD implementation opens up the possibility to study magneto-hydrodynamical systems on a moving mesh beyond the ideal MHD approximation.

    2015-01-01

    This paper extends theory and research concerning cultural models of development beyond family and demographic matters to a broad range of additional factors, including government, education, human rights, daily social conventions, and religion. Developmental idealism is a cultural model—a set of beliefs and values—that identifies the appropriate goals of development and the ends for achieving these goals. It includes beliefs about positive cause and effect relationships among such factors as economic growth, educational achievement, health, and political governance, as well as strong values regarding many attributes, including economic growth, education, small families, gender equality, and democratic governance. This cultural model has spread from its origins among the elites of northwest Europe to elites and ordinary people throughout the world. Developmental idealism has become so entrenched in local, national, and global social institutions that it has now achieved a taken-for-granted status among many national elites, academics, development practitioners, and ordinary people around the world. We argue that developmental idealism culture has been a fundamental force behind many cultural clashes within and between societies, and continues to be an important cause of much global social change. We suggest that developmental idealism should be included as a causal factor in theories of human behavior and social change. PMID:26457325

  2. Idealism and realism in International Relations: an ontological debate

    Directory of Open Access Journals (Sweden)

    Vitor Ramon Fernandes

    2016-11-01

    Full Text Available The debate between realism and idealism continues to mark the discipline of International Relations. On the one hand, realism argues that international politics is a struggle for power and a quest for survival, which results in a condition of permanent conflict between States without any possibility of evolution or progress. On the other hand, idealism considers it possible to build a world of peaceful coexistence, prosperity and well-being, achieved through cooperation and based on values and aspirations shared by humans. The object of this article is to analyse the debate between idealism and realism, considering it as an ontological debate and taking into account the controversy it has generated. The argument presented here is that both realism and idealism are two responses to the creation and maintenance of international order, that is, how States relate in international society; however these responses are not mutually exclusive and can coexist in constant tension with one another. An analysis of internationalist thought of two authors, Hans Morgenthau and Raymond Aron, is also presented, which relates to how they are positioned in this debate as well as International Relations as a whole.

    Full Text Available We examined whether implicit measures of actual and ideal body image can be used to predict body dissatisfaction in young female adults. Participants completed two Implicit Relational Assessment Procedures (IRAPs to examine their implicit beliefs concerning actual (e.g., I am thin and desired ideal body image (e.g., I want to be thin. Body dissatisfaction was examined via self-report questionnaires and rating scales. As expected, differences in body dissatisfaction exerted a differential influence on the two IRAP scores. Specifically, the implicit belief that one is thin was lower in participants who exhibited a high degree of body dissatisfaction than in participants who exhibited a low degree of body dissatisfaction. In contrast, the implicit desire to be thin (i.e., thin ideal body image was stronger in participants who exhibited a high level of body dissatisfaction than in participants who were less dissatisfied with their body. Adding further weight to the idea that both IRAP measures captured different underlying constructs, we also observed that they correlated differently with body mass index, explicit body dissatisfaction, and explicit measures of actual and ideal body image. More generally, these findings underscore the advantage of using implicit measures that incorporate relational information relative to implicit measures that allow for an assessment of associative relations only.

  7. Coupling Ideality of Integrated Planar High-Q Microresonators

    Chip-scale optical microresonators with integrated planar optical waveguides are useful building blocks for linear, nonlinear, and quantum-optical photonic devices alike. Loss reduction through improving fabrication processes results in several integrated microresonator platforms attaining quality (Q ) factors of several millions. Beyond the improvement of the quality factor, the ability to operate the microresonator with high coupling ideality in the overcoupled regime is of central importance. In this regime, the dominant source of loss constitutes the coupling to a single desired output channel, which is particularly important not only for quantum-optical applications such as the generation of squeezed light and correlated photon pairs but also for linear and nonlinear photonics. However, to date, the coupling ideality in integrated photonic microresonators is not well understood, in particular, design-dependent losses and their impact on the regime of high ideality. Here we investigate design-dependent parasitic losses described by the coupling ideality of the commonly employed microresonator design consisting of a microring-resonator waveguide side coupled to a straight bus waveguide, a system which is not properly described by the conventional input-output theory of open systems due to the presence of higher-order modes. By systematic characterization of multimode high-Q silicon nitride microresonator devices, we show that this design can suffer from low coupling ideality. By performing 3D simulations, we identify the coupling to higher-order bus waveguide modes as the dominant origin of parasitic losses which lead to the low coupling ideality. Using suitably designed bus waveguides, parasitic losses are mitigated with a nearly unity ideality and strong overcoupling (i.e., a ratio of external coupling to internal resonator loss rate >9 ) are demonstrated. Moreover, we find that different resonator modes can exchange power through the coupler, which, therefore

  8. Influence of non-ideality on condensation to aerosol

    2009-02-01

    Full Text Available Secondary organic aerosol (SOA is a complex mixture of water and organic molecules. Its composition is determined by the presence of semi-volatile or non-volatile compounds, their saturation vapor pressure and activity coefficient. The activity coefficient is a non-ideality effect and is a complex function of SOA composition. In a previous publication, the detailed chemical mechanism (DCM for α-pinene oxidation and subsequent aerosol formation BOREAM was presented. In this work, we investigate with this DCM the impact of non-ideality by simulating smog chamber experiments for α-pinene degradation and aerosol formation and taking the activity coefficient into account of all molecules in the aerosol phase. Several versions of the UNIFAC method are tested for this purpose, and missing parameters for e.g. hydroperoxides and nitrates are inferred from fittings to activity coefficient data generated using the SPARC model. Alternative approaches to deal with these missing parameters are also tested, as well as an activity coefficient calculation method based on Hansen solubility parameters (HSP. It turns out that for most experiments, non-ideality has only a limited impact on the interaction between the organic molecules, and therefore on SOA yields and composition, when water uptake is ignored. The reason is that often, the activity coefficient is on average close to 1 and, specifically for high-VOC experiments, partitioning is not very sensitive on the activity coefficient because the equilibrium is shifted strongly towards condensation. Still, for ozonolysis experiments with low amounts of volatile organic carbon (low-VOC, the UNIFAC parameterization of Raatikainen et al. leads to significantly higher SOA yields (by up to a factor 1.6 compared to the ideal case and to other parameterizations. Water uptake is model dependent, in the order: ideal > UNIFAC-Raatikainen > UNIFAC-Peng > UNIFAC-Hansen ≈ UNIFAC-Magnussen ≈ UNIFAC-Ming. In the absence

    Full Text Available The objective of this study was to develop pitanga nectar formulations in which sucrose was replaced with different sweeteners. Consumer tests were conducted with 50 fruit juice consumers, and a just-about-right scale was used to determine the ideal pulp dilution and ideal sweetness with sucrose. Furthermore, the adequate concentrations of six sweeteners were determined to obtain the equivalent sweetness of sucrose using relative to these concentrations the magnitude estimation model with 19 selected assessors. The ideal dilution test resulted in 25% pulp, and the ideal sweetness test, 10% sucrose. Sweetener concentrations to replace sucrose were 0.0160%, 0.0541%, 0.1000%, 0.0999%, 0.0017%, and 0.0360%, respectively, for sucralose, aspartame, stevia 40% rebaudioside A, stevia 95% rebaudioside A, neotame, and a 2:1 cyclamate/saccharin blend. These results can be used to prepare pitanga nectar with different sweeteners and obtain the same sweetness intensity in less caloric products than that of nectar prepared with sucrose.

    Perfect liquid mixing but no solid diffusion is assumed in normal freezing. In addition, the molar compositions of the freezing solid and remaining liquid, respectively, follow the solidus and liquidus curves of the constitutional diagram. For the linear case, in which both the liquidus and solidus are perfectly straight lines, the normal freezing equation giving the fraction solidified at each melt temperature and the solute concentration profile in the frozen solid was determined as early as 1902, and has since been repeatedly published. Corresponding equations for quadratic, cubic or higher-degree liquidus and solidus lines have also been obtained. The equation of normal freezing for ideal ternary liquid solutions solidified into ideal solid solutions of the pseudobinary type is given. Sample computations with the use of this new equation were made and are given for the Ga-Al-As system.

  18. Ideal and conventional feedback systems for RWM suppression

    International Nuclear Information System (INIS)

    Pustovitov, V.D.

    2002-01-01

    Feedback suppression of resistive wall modes (RWM) is studied analytically using a model based on a standard cylindrical approximation. Two feedback systems are compared: 'ideal', creating only the field necessary for RMW suppression, and 'conventional', like that used in the DIII-D tokamak and considered as a candidate for ITER. The widespread opinion that the feedback with poloidal sensors is better than that with radial sensors is discussed. It is shown that the 'conventional' feedback with radial sensors can be effective only in a limited range, while using the input signal from internal poloidal sensors allows easy fulfilment of the stability criterion. This is a property of the 'conventional' feedback, but the 'ideal' feedback would stabilise RWM in both cases. (author)

  20. Combined Ideal and Kinetic Effects on Reversed Shear Alfven Eigenmodes

    International Nuclear Information System (INIS)

    Gorelenkov, N.N.; Kramer, G.J.; Nazikian, R.

    2011-01-01

    A theory of Reversed Shear Alfven Eigenmodes (RSAEs) is developed for reversed magnetic field shear plasmas when the safety factor minimum, qmin, is at or above a rational value. The modes we study are known sometimes as either the bottom of the frequency sweep or the down sweeping RSAEs. We show that the ideal MHD theory is not compatible with the eigenmode solution in the reversed shear plasma with qmin above integer values. Corrected by special analytic FLR condition MHD dispersion of these modes nevertheless can be developed. Large radial scale part of the analytic RSAE solution can be obtained from ideal MHD and expressed in terms of the Legendre functions. The kinetic equation with FLR effects for the eigenmode is solved numerically and agrees with the analytic solutions. Properties of RSAEs and their potential implications for plasma diagnostics are discussed.

This method uses minimal assumptions and idealizes ion channel recordings without requiring a detailed user input or a priori assumptions about channel conductance and kinetics. Furthermore, we demonstrate...... that correlation analysis of conductance steps can resolve properties of single ion channels in recordings contaminated by signals from multiple channels. We first validated our methods on simulated data defined with a range of different signal-to-noise levels, and then showed that our algorithm can recover...... channel currents and their substates from recordings with multiple channels, even under conditions of high noise. We then tested the MDL algorithm on real experimental data from human PIEZO1 channels and found that our method revealed the presence of substates with alternate conductances....

  2. Description of Muzzle Blast by Modified Ideal Scaling Models

    Directory of Open Access Journals (Sweden)

    Kevin S. Fansler

    1998-01-01

    Full Text Available Gun blast data from a large variety of weapons are scaled and presented for both the instantaneous energy release and the constant energy deposition rate models. For both ideal explosion models, similar amounts of data scatter occur for the peak overpressure but the instantaneous energy release model correlated the impulse data significantly better, particularly for the region in front of the gun. Two parameters that characterize gun blast are used in conjunction with the ideal scaling models to improve the data correlation. The gun-emptying parameter works particularly well with the instantaneous energy release model to improve data correlation. In particular, the impulse, especially in the forward direction of the gun, is correlated significantly better using the instantaneous energy release model coupled with the use of the gun-emptying parameter. The use of the Mach disc location parameter improves the correlation only marginally. A predictive model is obtained from the modified instantaneous energy release correlation.

  3. Study on Product Innovative Design Process Driven by Ideal Solution

    Zhang, Fuying; Lu, Ximei; Wang, Ping; Liu, Hui

    Product innovative design in companies today relies heavily on individual members’ experience and creative ideation as well as their skills of integrating creativity and innovation tools with design methods agilely. Creative ideation and inventive ideas generation are two crucial stages in product innovative design process. Ideal solution is the desire final ideas for given problem, and the striving reaching target for product design. In this paper, a product innovative design process driven by ideal solution is proposed. This design process encourages designers to overcome their psychological inertia, to foster creativity in a systematic way for acquiring breakthrough creative and innovative solutions in a reducing sphere of solution-seeking, and results in effective product innovative design rapidly. A case study example is also presented to illustrate the effectiveness of the proposed design process.

    2009-01-01

    The theory of nonlinear transport is elaborated to determine the Burnett transport properties of non-ideal multi-element plasma and neutral systems. The procedure for the comparison of the phenomenological conservation equations of a continuous dense medium and the microscopic equations for dynamical variable operators is used for the definition of these properties. The Mori algorithm is developed to derive the equations of motion of dynamical value operators of a non-ideal system in the form of the generalized nonlinear Langevin equations. In consequence, the microscopic expressions of transport coefficients corresponding to second-order thermal disturbances (temperature, mass velocity, etc) have been found in the long wavelength and low frequency limits

    We describe a quantitative method to assess repeated stair stepping stability. In both the mediolateral (ML) and anterioposterior (AP) directions, the trajectory of the subject's center of mass (COM) was compared to an ideal sinusoid. The two identified sinusoids were unique in each direction but coupled. Two dimensionless numbers-the mediolateral instability index (IML) and AP instability index (IAP)-were calculated using the COM trajectory and ideal sinusoids for each subject with larger index values resulting from less stable performance. The COM trajectories of nine nonimpaired controls and six patients diagnosed with unilateral or bilateral vestibular labyrinth hypofunction were analyzed. The average IML and IAP values of labyrinth disorder patients were respectively 127% and 119% greater than those of controls (panalysis distinguishes persons with labyrinth disorder from those without. The COM trajectories also identify movement inefficiencies attributable to vestibulopathy.

    2014-01-01

    This paper examines the role of developmental thinking in the making of family values. We analyze survey data collected from Gansu Province in China with regular and multilevel logit models. The results show that individuals’ endorsement of neolocal residence, self-choice marriage, gender egalitarianism, late marriage for women, and low fertility depends on the conjunction of preference for development and beliefs in its association with those family attributes, which we term developmental idealism associational evaluation. Furthermore, such impact of developmental thinking on family values holds robust in the presence of indigenous ideational forces, in this case Islamic religion. Although Islam influences family values in the opposite direction than developmental ideas do, the effect of Developmental Idealism associational evaluation does not differ significantly between Muslims and non-Muslims.

    A reversed shear Alfven eigenmodes (RSAEs) theory has been developed for reversed magnetic field shear plasmas when the safety factor minimum, q min , is at or above a rational value. The modes we study are known sometimes as either the bottom of the frequency sweep or the down sweeping RSAEs. We show that, strictly speaking, the ideal MHD theory is not compatible with the eigenmode solution in the reversed shear plasma with q min above integer values. Corrected by a special analytic finite Larmor radius (FLR) condition, MHD dispersion of these modes nevertheless can be developed. Numerically, MHD structure can serve as a good approximation for the RSAEs.The large radial scale part of the analytic RSAE solution can be obtained from ideal MHD and expressed in terms of the Legendre functions. The kinetic equation with FLR effects for the eigenmode is solved numerically and agrees with the analytic solutions. Properties of RSAEs and their potential implications for plasma diagnostics are discussed.

  8. Effects of entanglement in an ideal optical amplifier

    Franson, J. D.; Brewster, R. A.

    2018-04-01

    In an ideal linear amplifier, the output signal is linearly related to the input signal with an additive noise that is independent of the input. The decoherence of a quantum-mechanical state as a result of optical amplification is usually assumed to be due to the addition of quantum noise. Here we show that entanglement between the input signal and the amplifying medium can produce an exponentially-large amount of decoherence in an ideal optical amplifier even when the gain is arbitrarily close to unity and the added noise is negligible. These effects occur for macroscopic superposition states, where even a small amount of gain can leave a significant amount of which-path information in the environment. Our results show that the usual input/output relation of a linear amplifier does not provide a complete description of the output state when post-selection is used.

    Detailed Monte Carlo calculations have been performed for three distinct configurations of an idealized fast critical assembly. This idealized assembly was based on the LMFBR benchmark critical assembly ZPR-6/7. In the first configuration, the entire core was loaded with the plate unit cell of ZPR-6/7. In the second configuration, the entire core was loaded with the ZPR sodium-filled pin calandria. The actual ZPR pin calandria are loaded with mixed (U,Pu) oxide pins which closely match the composition of the ZPR-6/7 plate unit cell. For the present study, slight adjustments were made in the atom concentrations and the length of the pin calandria in order to make the core boundaries and average composition for the pin-cell configuration identical to those of the plate-cell configuration. In the third configuration, the core was homogeneous, again with identical core boundaries and average composition as the plate and pin configurations

  14. Two Fundamental Problems and Two Periods of German Speculative Idealism

    Directory of Open Access Journals (Sweden)

    V. ZOLOTUKHIN

    2015-02-01

    Full Text Available The author’s concerns are with the philosophical and theological problems integral to German Speculative Idealism. Two key ideas permeated the whole of German Idealism: the idea of divine self-realization / self-understanding and the idea of gravitating between the poles of theism and pantheism. The author attempts to explain how these two ideas are related throughout the course of German Idealism. He includes in this study not only Fichte /the elder/, Schelling, and Hegel, but also the so-called speculative theists (Fichte /the younger/ and others, whose thought in both ideology and methodology resembles that of Schelling and Hegel. The author demonstrates using the writings of the philosophers that the two ideas may be related though the concept of creativity . If God realizes himself in the world and through the world, then it makes sense to say that philosophical theology is replete with pantheism. But if the divine realization takes place ontologically before the process of creation and is in itself an act which takes place within the divine Being Himself, the process is then clearly theistic. Idealists of the older school do not link creation with the Absolute - they reject this point or they speak about creation in reference to the act of divine self-realization. Idealists of the younger generation, on the contrary, hold that the act of divine self-realization precedes that of creation. The author opines that it is this point which allows us to diff erentiate between a philosophical system which leans towards pantheism from one which tends toward theism. The older idealists were indeed mostly pantheists, while the younger generation was mostly theistic. In view of this, German Idealism may be considered to be divided into two periods

Making use of polylogarithm functions we derive a closed and unified expression for their densities. It is shown that both type of gases are essentially inequivalent, and only in the non-relativistic limit the spinless and equal mass Bose and Fermi gases are equivalent as known in the literature.

    Highlights : • A direct approach is used to solve the Riemann problem for dusty ideal polytropic gas. • An analytical solution to the Riemann problem for dusty gas flow is obtained. • The existence and uniqueness of the solution in dusty gas is discussed. • Properties of elementary wave solutions of Riemann problem are discussed. • Effect of mass fraction of solid particles on the solution is presented. - Abstract: The Riemann problem for a quasilinear hyperbolic system of equations governing the one dimensional unsteady flow of an ideal polytropic gas with dust particles is solved analytically without any restriction on magnitude of the initial states. The elementary wave solutions of the Riemann problem, that is shock waves, rarefaction waves and contact discontinuities are derived explicitly and their properties are discussed, for a dusty gas. The existence and uniqueness of the solution for Riemann problem in dusty gas is discussed. Also the conditions leading to the existence of shock waves or simple waves for a 1-family and 3-family curves in the solution of the Riemann problem are discussed. It is observed that the presence of dust particles in an ideal polytropic gas leads to more complex expression as compared to the corresponding ideal case; however all the parallel results remain same. Also, the effect of variation of mass fraction of dust particles with fixed volume fraction (Z) and the ratio of specific heat of the solid particles and the specific heat of the gas at constant pressure on the variation of velocity and density across the shock wave, rarefaction wave and contact discontinuities are discussed.

    The Bose-Einstein condensation (BEC) critical temperature in a relativistic ideal Bose gas of identical bosons, with and without the antibosons expected to be pair-produced abundantly at sufficiently hot temperatures, is exactly calculated for all boson number densities, all boson point rest masses, and all temperatures. The Helmholtz free energy at the critical BEC temperature is lower with antibosons, thus implying that omitting antibosons always leads to the computation of a metastable state.

    A mathematically precise treatment is given of the well-known Bose-Einstein condensation of an ideal gas in the grand canonical ensemble at fixed density. The method works equally well for any of the standard boundary conditions and it is shown that the finite volume activity converges and that in three dimensions condensation occurs for Dirichlet, Neumann, periodic, and repulsive walls.

  2. Calibration of non-ideal thermal conductivity sensors

    Full Text Available A popular method for measuring the thermal conductivity of solid materials is the transient hot needle method. It allows the thermal conductivity of a solid or granular material to be evaluated simply by combining a temperature measurement with a well-defined electrical current flowing through a resistance wire enclosed in a long and thin needle. Standard laboratory sensors that are typically used in laboratory work consist of very thin steel needles with a large length-to-diameter ratio. This type of needle is convenient since it is mathematically easy to derive the thermal conductivity of a soft granular material from a simple temperature measurement. However, such a geometry often results in a mechanically weak sensor, which can bend or fail when inserted into a material that is harder than expected. For deploying such a sensor on a planetary surface, with often unknown soil properties, it is necessary to construct more rugged sensors. These requirements can lead to a design which differs substantially from the ideal geometry, and additional care must be taken in the calibration and data analysis. In this paper we present the performance of a prototype thermal conductivity sensor designed for planetary missions. The thermal conductivity of a suite of solid and granular materials was measured both by a standard needle sensor and by several customized sensors with non-ideal geometry. We thus obtained a calibration curve for the non-ideal sensors. The theory describing the temperature response of a sensor with such unfavorable length-to-diameter ratio is complicated and highly nonlinear. However, our measurements reveal that over a wide range of thermal conductivities there is an almost linear relationship between the result obtained by the standard sensor and the result derived from the customized, non-ideal sensors. This allows for the measurement of thermal conductivity values for harder soils, which are not easily accessible when using

    Applicant interviews for urology residency positions are a stressful and costly process for students, faculty, and staff. We conducted a prospective survey to better determine what urology applicants perceive as an ideal interview process to gain sufficient knowledge about a training program. A questionnaire was anonymously completed by all urology residency applicants interviewing at the Medical College of Wisconsin from 2007 to 2013. Questionnaire subject headings included "ideal interview format," "factors contributing to understanding the residency program," and "factors contributing to final rank list order." Questionnaires were distributed to and completed by 221 senior medical students applying for a urology residency position. Most respondents (>80%) reported they would prefer to partake in 5 to 7 faculty interviews in an office setting with the total interview process spanning half to three-fourths of the workday. Spending time with current residents was considered the most valuable tool to acquire knowledge about a residency program. The most important criteria when ranking a program were resident satisfaction, resident operative experience, and perceived strength of faculty. Academic urology programs may wish to consider applicant ideals when organizing residency interviews. Interaction with current residents appears to be the most valuable resource allowing applicants to garner knowledge about a urology training program.

    Why do people give to strangers? We propose that people trust and give more to those whose emotional expressions match how they ideally want to feel ("ideal affect match"). European Americans and Koreans played multiple trials of the Dictator Game with recipients who varied in emotional expression (excited, calm), race (White, Asian) and sex (male, female). Consistent with their culture's valued affect, European Americans trusted and gave more to excited than calm recipients, whereas Koreans trusted and gave more to calm than excited recipients. These findings held regardless of recipient race and sex. We then used fMRI to probe potential affective and mentalizing mechanisms. Increased activity in the nucleus accumbens (associated with reward anticipation) predicted giving, as did decreased activity in the right temporo-parietal junction (rTPJ; associated with reduced belief prediction error). Ideal affect match decreased rTPJ activity, suggesting that people may trust and give more to strangers whom they perceive to share their affective values. © The Author (2017).

  9. The Noborder Movement: Interpersonal Struggle with Political Ideals

    Directory of Open Access Journals (Sweden)

    Leslie Gauditz

    2017-09-01

    Full Text Available Over the last decade, self-organized refugee protests in Europe have increased. One strand of activism in Europe, noborder, involves a transnational network of people who are heterogeneous with regards to legal status, race, or individual history of migration, but who share decolonial, anti-capitalist ideals that criticize the nation-state. Noborder activists embrace prefigurative strategies, which means enacting political ideals in their everyday life. This is why this article asks: How do noborder activists try to meet their political ideals in their everyday practices, and what effects do these intentions entail? Noborder practices take place at the intersection of self-organization as a reference to migrants’ legal status or identity, on the one hand, and self-organization as anti-hierarchical forms of anarchist-autonomous organization, on the other. On the basis of empirical findings of a multi-sited ethnography in Germany and Greece, this article conceptualizes that noborder creates a unique space for activists to meet in which people try to work productively through conflicts they see as being produced by a global system of inequalities. This demanding endeavor involves social pressure to self-reflect and to transform interpersonal relationships. Broader society could learn from such experiences to build more inclusive, heterogeneous communities.

    Well-controlled quantum systems can potentially be used as quantum simulators. However, a quantum simulator is inevitably perturbed by coupling to additional degrees of freedom. This constitutes a major roadblock to useful quantum simulations. So far there are only limited means to understand the effect of perturbation on the results of quantum simulation. Here we present a method which, in certain circumstances, allows for the reconstruction of the ideal result from measurements on a perturbed quantum simulator. We consider extracting the value of the correlator 〈Ôi(t ) Ôj(0 ) 〉 from the simulated system, where Ôi are the operators which couple the system to its environment. The ideal correlator can be straightforwardly reconstructed by using statistical knowledge of the environment, if any n -time correlator of operators Ôi of the ideal system can be written as products of two-time correlators. We give an approach to verify the validity of this assumption experimentally by additional measurements on the perturbed quantum simulator. The proposed method can allow for reliable quantum simulations with systems subjected to environmental noise without adding an overhead to the quantum system.

  11. Ideal Gas Resonance Scattering Kernel Routine for the NJOY Code

    International Nuclear Information System (INIS)

    Rothenstein, W.

    1999-01-01

    In a recent publication an expression for the temperature-dependent double-differential ideal gas scattering kernel is derived for the case of scattering cross sections that are energy dependent. Some tabulations and graphical representations of the characteristics of these kernels are presented in Ref. 2. They demonstrate the increased probability that neutron scattering by a heavy nuclide near one of its pronounced resonances will bring the neutron energy nearer to the resonance peak. This enhances upscattering, when a neutron with energy just below that of the resonance peak collides with such a nuclide. A routine for using the new kernel has now been introduced into the NJOY code. Here, its principal features are described, followed by comparisons between scattering data obtained by the new kernel, and the standard ideal gas kernel, when such comparisons are meaningful (i.e., for constant values of the scattering cross section a 0 K). The new ideal gas kernel for variable σ s 0 (E) at 0 K leads to the correct Doppler-broadened σ s T (E) at temperature T

    Full text: A main research objective of KSTAR (Korea Superconducting Tokamak Advanced Research) device is to demonstrate the steady-state operation capability of high-performance AT (Advanced Tokamak) mode. To meet this goal, it is critical for KSTAR to have a good MHD stability boundary, particularly against the high-beta ideal instabilities such as the external kink and the ballooning modes. To support this MHD stability KSTAR has been designed to have a strong plasma shape and a close interval between plasma and passive- plate wall. During the conceptual design phase of KSTAR, a preliminary study was performed to estimate the high beta MHD stability limit of KSTAR target AT mode using PEST and VACUUM codes and it was shown that the target AT mode can be stable up to β N ∼ 5 with a well-defined plasma pressure and current profiles. Recently, a new calculation has been performed to estimate the ideal stability limit in various KSTAR operating conditions using DCON code, and it has been observed that there is some difference between the new and old calculation results, particularly in the dependence of the maximum β N value on the toroidal mode number. Here, we thus present a more detailed analysis of the ideal MHD stability limit of KSTAR target AT mode using various codes, which include GATO as well as PEST and DCON, in the comparison of calculation results among the three codes.

  13. Thin-ideal internalization: How much is too much?

    Schaefer, Lauren M; Burke, Natasha L; Thompson, J Kevin

    2018-03-16

    Internalization of the thin-ideal is a risk factor for eating disorders that frequently persists into recovery and increases patient risk for relapse. Addressing thin-ideal internalization as a core element of eating disorder prevention and treatment produces significant reductions in eating pathology. However, research has not yet quantified levels of thin-ideal internalization that may signal increased versus decreased risk for disordered eating. To address this gap in the literature, receiver operating characteristic (ROC) curve analysis was used to identify a thin-ideal internalization cutoff score that signified clinically-meaningful eating disorder pathology. 787 college women (age M = 20.17, SD = 2.41; BMI M = 23.58, SD = 5.29) were classified as "healthy" (N = 717) or those with significant disordered eating (N = 70) using established clinical cutoffs for the Eating Disorder Examination-Questionnaire. ROC curve analysis was used to test the performance of the Sociocultural Attitudes Towards Appearance Questionnaire-4 (SATAQ-4) Internalization: Thin/Low Body Fat subscale in predicting disordered eating status, and to identify a cutoff score that maximized sensitivity and specificity to discriminate between healthy and disordered eating samples. Mean SATAQ-4 internalization scores were 3.29 (SD = 0.92) and 4.27 (SD = 0.62) for healthy and disordered eating participants, respectively. The SATAQ-4 internalization scores were good predictors of disordered eating status (area under the curve = 0.81, 95% CI: 0.76-0.86). The optimal cutoff of 3.78 (measured on a 1-5 Likert scale) yielded a sensitivity of 0.81 and specificity of 0.64. Overall, results provide preliminary support for the discriminant validity of SATAQ-4 thin internalization scores and suggest that even moderate levels of thin-ideal internalization may be predictive of clinically-significant eating pathology. It may be important for prevention and intervention work to actively seek to reduce

    Surgical innovation is essential for progress of surgical science, but its implementation comes with potential harms during the learning phase. The Balliol Collaboration has recommended a set of guidelines (Innovation, Development, Exploration, Assessment, Long-term study [IDEAL]) that permit innovation while minimizing complications. To utilize the IDEAL model of surgical innovation in the development of a novel surgical technique, robotic kidney transplantation (RKT) with regional hypothermia, and describe the process of discovery and development. Phase 0 (simulation) studies included the establishment of techniques for pelvic cooling, graft placement in a robotic prostatectomy model, and simulation of the RKT procedure in a cadaveric model. Phase 1 (innovation) studies began in January 2013 and involved treatment of a highly selective small group of patients (n=7), using the principles utilized in the phase 0 studies, at a tertiary referral center. IDEAL model implementation in the development of RKT with regional hypothermia. For phase 0 studies, the outcomes evaluated included pelvic and body temperature measurements, and technical feasibility assessment. The primary outcome during phase 1 was post-transplant graft function. Other outcomes measured were operative and ischemic times, perioperative complications, and intracorporeal graft surface temperature. Phase 0 (simulation phase): Pelvic cooling to 15-20(o)C was achieved reproducibly. Using the surgical approach developed for robotic radical prostatectomy, vascular and ureterovesical anastomoses could be done without redocking the robot. Phase 1 (innovation phase): All patients underwent live-donor RKT in the lithotomy position. All grafts functioned immediately. Mean console, anastomotic, and warm ischemia times were 154 min, 29 min, and 2 min, respectively. One patient was re-explored on postoperative day 1. Adherence to the IDEAL guidelines put forth by the Balliol Collaboration provided a practical

    Simple Summary The public, who also make up the largest proportion of consumers of animal products, often criticize farm animal industries in regards to their care and handling of farm animals. The U.S. swine industry has not been exempt from such criticisms. The aim of this study was to explore the views of the people not affiliated with the swine industry on what they perceived to be the ideal pig/pork farm, and their associated reasons. Through an online survey, participants were invited to respond to the following open-ended question: “What do you consider to be an ideal pig/pork farm and why are these characteristics important to you?”. Respondents considered animal care, profitability, farm size, compliance with sanitary, environmental rules and regulations, farm cleanliness and sanitary standards, and workers’ rights and welfare important, but also raised concerns relating to pigs’ quality of life including space to move, feeding, contact with outdoors or nature, absence of pain, suffering and mistreatment. Perspectives were also raised regarding the ideal farm as a profitable business operation, clean, and with optimal sanitary conditions. Respondents also emphasized naturalness, frequently stating that pigs should have access to the outdoors, and rejected the use of hormones, antibiotics, and other chemicals for the purposes of increasing production. Abstract Food animal production practices are often cited as having negative animal welfare consequences. The U.S. swine industry has not been exempt from such criticisms. Little is known, however, about how lay citizens who are not actively engaged in agricultural discussions, think about swine production.

    Cultures differ in the emotions they teach their members to value ("ideal affect"). We conducted 3 studies to examine whether leaders' smiles reflect these cultural differences in ideal affect. In Study 1, we compared the smiles of top-ranked American and Chinese government leaders, chief executive officers, and university presidents in their official photos. Consistent with findings that Americans value excitement and other high-arousal positive states more than Chinese, American top-ranked leaders (N = 98) showed more excited smiles than Chinese top-ranked leaders (N = 91) across occupations. In Study 2, we compared the smiles of winning versus losing political candidates and higher versus lower ranking chief executive officers and university presidents in the United States and Taiwan/China. American leaders (N = 223) showed more excited smiles than Taiwanese/Chinese leaders (N = 266), regardless of election outcome or ranking. In Study 3, we administered self-report measures of ideal affect in college student samples from 10 different nations (N = 1,267) and then 8 years later, coded the smiles that legislators from those nations showed in their official photos (N = 3,372). The more nations valued excitement and other high arousal positive states, the more their leaders showed excited smiles; similarly, the more nations valued calm and other low-arousal positive states, the more their leaders showed calm smiles. These results held after controlling for national differences in democratization, human development, and gross domestic product per capita. Together, these findings suggest that leaders' smiles reflect the affective states valued by their cultures. (c) 2016 APA, all rights reserved).

    Food animal production practices are often cited as having negative animal welfare consequences. The U.S. swine industry has not been exempt from such criticisms. Little is known, however, about how lay citizens who are not actively engaged in agricultural discussions, think about swine production. Thus, the aim of this study was to explore the views of people not affiliated with the swine industry on what they perceived to be the ideal pig/pork farm, and their associated reasons. Through an online survey, participants were invited to respond to the following open-ended question: "What do you consider to be an ideal pig/pork farm and why are these characteristics important to you?". Generally respondents considered animal welfare (e.g., space, freedom to move, and humane treatment), respondents considered the business operation role important for pork production (e.g., profitability, compliance with sanitary, environmental rules and regulations, and workers' rights), and naturalness (e.g., natural feeding, behaviours and life) important for pork production. Concerns relating to pigs' quality of life included space to move, feeding, contact with outdoors or nature, absence of pain, suffering and mistreatment. Perspectives were also raised regarding the ideal farm as a profitable business operation, clean, and with optimal sanitary conditions. Respondents also emphasized naturalness, frequently stating that pigs should have access to the outdoors, and rejected the use of hormones, antibiotics, and other chemicals for the purposes of increasing production. In summary, the findings of this study suggest that the U.S. swine industry should strive to adopt animal management practices that resonate with societal values, such as ensuring humane treatment, and the failure to do so could risk the sustainability of the swine industry.

  2. Near-ideal lasing with a uniform wiggler

    Over the years the Los Alamos FEL team has reduced or eliminated many of the experimental problems that resulted in non-ideal lasing. The major problems were accelerator instabilities that cause noise and fluctuations in current, energy, and timing; wakefield effects in the wiggler and beamline that introduce fluctuations in the beam's energy; and mirror nonlinearities caused by free carriers produced in the mirror by the high light levels, which caused extra light losses and interfered with the diagnostics. Lasing is not thought to be ideal in that it lacks major disturbing effects and is limited only by emittance, energy spread, and peak current. In this paper we describe the features of lasing that we have observed over a range of optical power of 1000, from the onset of lasing, to the threshold of the sideband instability, to the organization of regular optical spikes, to the region of chaotic spikes. Cavity-length detuning is presented as an ideal technique, in most circumstances, to completely suppress sidebands. With detuning one can easily switch operating modes from that giving the highest efficiency (chaotic spiking) to that giving the narrowest spectral line (no sidebands). Alternative techniques for sideband suppression normally use some kind of wavelength selective device (e.g., a grating) inserted in the cavity. With detuning, there is no need for such a device, and, therefore, no conflict between the wavelength control exerted by this extra optical component and that exerted by the energy of the electron beam. Lasing, therefore, starts easily, a shift in wavelength, i.e., chirp, is easily accomplished, and the consequences of inadequate control of the electron beam energy are not severe. 35 refs., 16 figs.

    Cultures differ in the emotions they teach their members to value (“ideal affect”). We conducted three studies to examine whether leaders’ smiles reflect these cultural differences in ideal affect. In Study 1, we compared the smiles of top ranked American and Chinese government leaders, chief-executive-officers (CEOs), and university presidents in their official photos. Consistent with findings that Americans value excitement and other high arousal positive states more than Chinese, American top ranked leaders (N = 98) showed more excited smiles than Chinese top ranked leaders (N = 91) across occupations. In Study 2, we compared the smiles of winning vs. losing political candidates and higher vs. lower ranking CEOs and university presidents in the US and Taiwan/China. American leaders (N = 223) showed more excited smiles than Taiwanese/Chinese leaders (N =266), regardless of election outcome or ranking. In Study 3, we administered self-report measures of ideal affect in college student samples from 10 different nations (N = 1,267) and then eight years later, coded the smiles that legislators from those nations showed in their official photos (N = 3,372). The more nations valued excitement and other high arousal positive states, the more their leaders showed excited smiles; similarly, the more nations valued calm and other low arousal positive states, the more their leaders showed calm smiles. These results held after controlling for national differences in GDP per capita, democratization, and human development. Together, these findings suggest that leaders’ smiles reflect the affective states valued by their cultures. PMID:26751631

    We present a monaural approach to speech segregation that estimates the ideal binary mask (IBM) by combining amplitude modulation spectrogram (AMS) features, pitch-based features and speech presence probability (SPP) features derived from noise statistics. To maintain a high mask estimation...... accuracy in the presence of various background noises, the system employs environment-specific segregation models and automatically selects the appropriate model for a given input signal. Furthermore, instead of classifying each timefrequency (T-F) unit independently, the a posteriori probabilities...... of speech and noise presence are evaluated by considering adjacent TF units. The proposed system achieves high classification accuracy....

  5. A Democratic Ideal? From Judicial Activism to Constitutionalization of Law

    Directory of Open Access Journals (Sweden)

    Luisa Fernanda García López

    2013-12-01

    Full Text Available The constitutionalization of law in Colombia is due to an active participation of the judge, in particular, of the constitutional judge. The judicial precedent source of law is an example of the inclusion of the judge on the constitutional stage as guarantor of democracy and law. The democratic ideal irreversibly includes the constitutional judge and his interpretations. The overinterpretation of law answers to a broad interpretation of the Constitution and to a building of norms that contribute something to fill the gaps in the law. Thus eoconstitutionalism is constitutionalizing the juridical order.

    Chakrabarti, Anindya S.; Chakrabarti, Bikas K.

    2009-10-01

    We develop a framework based on microeconomic theory from which the ideal gas like market models can be addressed. A kinetic exchange model based on that framework is proposed and its distributional features have been studied by considering its moments. Next, we derive the moments of the CC model (Eur. Phys. J. B 17 (2000) 167) as well. Some precise solutions are obtained which conform with the solutions obtained earlier. Finally, an output market is introduced with global price determination in the model with some necessary modifications.

  7. Ideal glass transitions in thin films: An energy landscape perspective

    Science.gov (United States)

    Truskett, Thomas M.; Ganesan, Venkat

    2003-07-01

    We introduce a mean-field model for the potential energy landscape of a thin fluid film confined between parallel substrates. The model predicts how the number of accessible basins on the energy landscape and, consequently, the film's ideal glass transition temperature depend on bulk pressure, film thickness, and the strength of the fluid-fluid and fluid-substrate interactions. The predictions are in qualitative agreement with the experimental trends for the kinetic glass transition temperature of thin films, suggesting the utility of landscape-based approaches for studying the behavior of confined fluids.

  8. Idealized Compression Ratio for a Screw Briquetting Press

    2012-01-01

    Full Text Available This paper deals with issues in determining the ideal compression ratio for a screw briquetting press. First, the principles of operation and a basic description of the main parts of a screw briquetting press are introduced. The next section describes the pressing space by means of 3D software. The pressing space was created using a Boolean subtract function. The final section of the paper measures the partial volumes of the pressing chamber in CATIA V5 by function of measuring. The measured values are substituted into the formula for the compression ratio, and the resulting evaluations are presented in the diagram in the conclusion of this paper.

    2000-03-13

    We obtain analytical formulas for the statistics, in particular, for the characteristic function and all cumulants, of the Bose-Einstein condensate in dilute weakly interacting and ideal equilibrium gases in the canonical ensemble via the particle-number-conserving operator formalism of Girardeau and Arnowitt. We prove that the ground-state occupation statistics is not Gaussian even in the thermodynamic limit. We calculate the effect of Bogoliubov coupling on suppression of ground-state occupation fluctuations and show that they are governed by a pair-correlation, squeezing mechanism.

  10. On the relativistic partition function of ideal gases

    International Nuclear Information System (INIS)

    Sinyukov, Yu.M.

    1983-01-01

    The covariant partition function method for ideal Boltzmann and Bose gases is developed within quantum field theory. This method is a basis to describe the statistical and thermodynamical properties of the gases in canonical, grand canonical and pressure ensembles in an arbitrary inertial system. It is shown that when statistical systems are described relativistically it is very important to take into account the boundary conditions. This is due to the fact that an equilibrium system is not closed mechanically. The results may find application in hadron physics. (orig.)

    2014-06-01

    Full Text Available In weakly coupled plasmas, it is common to describe the microfield using a Debye model. We examine here an “artificial” ideal one-component plasma with an infinite Debye length, which has been used for the test of line shape codes. We show that the infinite Debye length assumption can lead to a misinterpretation of numerical simulations results, in particular regarding the convergence of calculations. Our discussion is done within an analytical collision operator model developed for hydrogen line shapes in near-impact regimes. When properly employed, this model can serve as a reference for testing the convergence of simulations.

    The ideal MHD stability of poloidally asymmetric equilibria, which are typical of a tokamak reactor design with a single-null poloidal divertor is examined. As with symmetric equilibria, stability to non-axisymmetric modes improves with increasing triangularity and ellipticity, and with lower edge safety factor. Pressure profiles optimized with respect to ballooning stability are obtained for an asymmetric shape, resulting in ..beta../sub critical/ approx. = 5.7%. The corresponding value for an equivalent symmetric shape is ..beta../sub critical/ approx. = 6.5%.

    Using a narrow intercombination line in alkaline earth atoms to mitigate large inelastic losses, we explore the optical Feshbach resonance effect in an ultracold gas of bosonic 88 Sr. A systematic measurement of three resonances allows precise determinations of the optical Feshbach resonance strength and scaling law, in agreement with coupled-channel theory. Resonant enhancement of the complex scattering length leads to thermalization mediated by elastic and inelastic collisions in an otherwise ideal gas. Optical Feshbach resonance could be used to control atomic interactions with high spatial and temporal resolution.

    Feiereisen, William J.; Venkatapathy, Ethiraj

    1988-01-01

    In the present work, complete flow fields around generic space vehicles in supersonic and hypersonic flight regimes are studied numerically. Numerical simulation is performed with a flux-split, time asymptotic viscous flow solver that incorporates a generalized equilibrium chemistry model. Solutions to generic problems at various altitude and flight conditions show the complexity of the flow, the equilibrium chemical dissociation and its effect on the overall flow field. Viscous ideal gas solutions are compared against equilibrium gas solutions to illustrate the effect of equilibrium chemistry. Improved solution accuracy is achieved through adaptive grid refinement.

    1974-01-01

    The steady flow of an ideal gas past a conical body is investigated by the method of matched asymptotic expansions, with particular emphasis on the flow near the singular ray occurring in linearized theory. The first-order problem governing the flow in this region is formulated, leading to the equation of Kuo, and an approximate solution is obtained in the case of compressive flow behind the main front. This solution is compared with the results of previous investigations with a view to assessing the applicability of the Lighthill-Whitham theories.

    Bakkari, C.; Mahdou, N.

    2006-12-01

    The goal of this paper is to exhibit a class of Gaussian non-coherent rings R (with zero-divisors) such that wdim(R) = ∞ and fPdim(R) is always at most one and also exhibits a new class of rings (with zerodivisors) which are neither locally Noetherian nor locally domain where Gaussian polynomials have a locally principal content. For this purpose, we study the possible transfer of the 'Gaussian' property and the property 'the content ideal of a Gaussian polynomial is locally principal' to various trivial extension contexts. This article includes a brief discussion of the scopes and limits of our result. (author)

    The investigation of the spectrum of the simplified differential equation describing the variation of the amplitude of the ideal MHD ballooning instability along magnetic field lines constitutes a multiparameter Schroedinger eigenvalue problem. An exact eigenvalue relation for the discrete part of the spectrum is obtained in terms of the oblate spheroidal functions. The dependence of the eigenvalues lambda on the two free parameters γ 2 and μ 2 of the equation is discussed, together with certain analytical approximations in the limits of small and large γ 2 . A brief review of the principal properties of the spheroidal functions is given in an appendix

    Previous derivations of the ideal solar cell equation based on Shockley's p-n junction diode theory implicitly assume negligible effects of photon recycling. This paper derives the equation in the presence of photon recycling that modifies the values of dark saturation and light-generated currents, using an approach applicable to arbitrary three-dimensional geometries with arbitrary doping profile and variable band gap. The work also corrects an error in previous work and proves the validity of the reciprocity theorem for charge collection in such a more general case with the previously neglected junction depletion region included

    Gillespie, Alex; Reader, Tom; Cornish, Flora; Campbell, Catherine

    2014-01-01

    Inclusive, unconstrained and honest communication is widely advocated as beneficial and ethical. We critically explore this assumption by reflecting upon our research in acute care, informal care and public health. Using Habermas' ideals of dialogue to conceptualise ideal speech, we concur with observations that health care is often characterised by intractable exclusions and constraints. Rather than advocating implementing the ideals of dialogue, however, we examine how people adapt to these difficult and intransigent contexts. Non-ideal contexts, we find, sometimes call for non-ideal responses. Deception and furthering personal interests, and thus departing from the ideals of dialogue, can be adaptive responses.

  9. Intraperiodontal pocket: An ideal route for local antimicrobial drug delivery

    2012-01-01

    Full Text Available Periodontal pockets act as a natural reservoir filled with gingival crevicular fluid for the controlled release delivery of antimicrobials directly. This article reflects the present status of nonsurgical controlled local intrapocket delivery of antimicrobials in the treatment of periodontitis. These sites have specialty in terms of anatomy, permeability, and their ability to retain a delivery system for a desired length of time. A number of antimicrobial products and the composition of the delivery systems, its use, clinical results, and their release are summarized. The goal in using an intrapocket device for the delivery of an antimicrobial agent is the achievement and maintenance of therapeutic drug concentration for the desired period of time. Novel controlled drug delivery system are capable of improving patient compliance as well as therapeutic efficacy with precise control of the rate by which a particular drug dosage is released from a delivery system without the need for frequent administration. These are considered superior drug delivery system because of low cost, greater stability, non-toxicity, biocompatibility, non-immunogenicity, and are biodegradable in nature. This review also focus on the importance and ideal features of periodontal pockets as a drug delivery platform for designing a suitable dosage form along with its potential advantage and limitations. The microbes in the periodontal pocket could destroy periodontal tissues, and a complete knowledge of these as well as an ideal treatment strategy could be helpful in treating this disease.

    Full Text Available The article outlines the possible approaches in the mathematical computations of integrated behavioral units in functional systems supporting homeostasis through in behavioral changes. By an imbalance in the homeostasis system which initiates adaptive behavior we assume: for metabolism – a departure of the parameters from the “normal zone” to the level of a suprathreshold sensitivity of the receptors; for structures of the psychological and social spectra – to the “cognized-not cognized”, “acceptable-not acceptable” levels. For the system analysis of goal-directed behavior dynamics, we present a combination of the “creation – retention” of the ideal image of the goal and the entire effector structure of the integrated behavioral unit by introducing an integrating term, motivational gradient. The integrated Behavioral Unit (BU is described as a psychophysiological metamer in behavioral continuum, including a mathematical description of the BU as a whole including its elements viz., the ideal image of the goal and the motivational gradient. The hemodynamic equivalent of the motivational gradient (the scalar gradient and subjective time (the time marker are used as the BU markers. For the mathematical description, we use the mathematical apparatus of topological spaces and elements of the string theory to open up opportunities for new approaches in psychology and neurobiology.

    1985-01-01

    A series of seven idealized bronze-Nb 3 Sn composites were manufactured by the MJR process with varying matrix to filament ratios and pure Nb and Nb 0.8 wt.% Ti cores. The central core of each composite was sealed by a diffusion barrier which results in each filament having an identical source of tin. Initial evaluations of the composites from critical current and transmission electron microscopy measurements are presented and their properties compared to standard MJR composites. The Nb 3 Sn current density does not appear to be a strong function of bronze to Nb ratio over the range 2.4 to 3.2:1. The standard MJR composites have higher critical current densities than the idealized composites. It is proposed that the major reason for the increased current density of the normal MJR conductors is the intrinsically higher quality of the filaments close to the central tin core. It is postulated that the high Sn content of the bronze surrounding these filaments leads to an intrinsically higher Nb 3 Sn filament current density

  12. IDEAL characterization of isometry classes of FLRW and inflationary spacetimes

    Canepa, Giovanni; Dappiaggi, Claudio; Khavkine, Igor

    2018-02-01

    In general relativity, an IDEAL (Intrinsic, Deductive, Explicit, ALgorithmic) characterization of a reference spacetime metric g 0 consists of a set of tensorial equations T[g]  =  0, constructed covariantly out of the metric g, its Riemann curvature and their derivatives, that are satisfied if and only if g is locally isometric to the reference spacetime metric g 0. The same notion can be extended to also include scalar or tensor fields, where the equations T[g, φ]=0 are allowed to also depend on the extra fields ϕ. We give the first IDEAL characterization of cosmological FLRW spacetimes, with and without a dynamical scalar (inflaton) field. We restrict our attention to what we call regular geometries, which uniformly satisfy certain identities or inequalities. They roughly split into the following natural special cases: constant curvature spacetime, Einstein static universe, and flat or curved spatial slices. We also briefly comment on how the solution of this problem has implications, in general relativity and inflation theory, for the construction of local gauge invariant observables for linear cosmological perturbations and for stability analysis.

  13. The pressure exerted by a confined ideal gas

    International Nuclear Information System (INIS)

    Pang Hai; Dai Wusheng; Xie Mi

    2011-01-01

    In this paper, we study the pressure exerted by a confined ideal gas on the container boundary and we introduce a surface force in gases. First, the general expression for the local surface pressure tensor is obtained. We find, by examples, that the pressure vanishes at the edges of a box, peaks at the middle of the surface and its magnitude for different statistics satisfies p Fermi > p classical > p Bose on every boundary point. Then, the relation between the surface pressure tensor and generalized forces is studied. Based on the relation, we find that a confined ideal gas can exert forces whose effect is to reduce the total surface area of the boundary of an incompressible object. The force provides mechanisms for several mechanical effects. (1) The force contributes to the adhesion of two thin films in contact with each other. We derive an expression for the adhesion force between two square sheets, estimate its magnitude, and also give a method for distinguishing it from other adhesion forces. (2) The force can lead to the recoiling of a DNA-like column. We study the recoiling process using a simple model and find a deviation from the result given in the thermodynamic limit, which is in accordance with experiments. (3) An open container immersed in a gas can be compressed by this force like the Casimir effect. We discuss the effect for various geometries. (paper)

    2015-12-01

    We investigate nonequilibrium steady states of driven-dissipative ideal quantum gases of both bosons and fermions. We focus on systems of sharp particle number that are driven out of equilibrium either by the coupling to several heat baths of different temperature or by time-periodic driving in combination with the coupling to a heat bath. Within the framework of (Floquet-)Born-Markov theory, several analytical and numerical methods are described in detail. This includes a mean-field theory in terms of occupation numbers, an augmented mean-field theory taking into account also nontrivial two-particle correlations, and quantum-jump-type Monte Carlo simulations. For the case of the ideal Fermi gas, these methods are applied to simple lattice models and the possibility of achieving exotic states via bath engineering is pointed out. The largest part of this work is devoted to bosonic quantum gases and the phenomenon of Bose selection, a nonequilibrium generalization of Bose condensation, where multiple single-particle states are selected to acquire a large occupation [Phys. Rev. Lett. 111, 240405 (2013)]. In this context, among others, we provide a theory for transitions where the set of selected states changes, describe an efficient algorithm for finding the set of selected states, investigate beyond-mean-field effects, and identify the dominant mechanisms for heat transport in the Bose-selected state.

    2016-04-01

    The ideal male jaw angle has not been established. With the advent of additive manufacturing, precise customized shaping is a reality. This study aimed to define the ideal masculine mandibular angle as an aid for 3-dimensional (3D) design. An Internet survey was conducted using black/white photographs of celebrities and non-celebrities. Preferences regarding gonial angle (profile and frontal views), intergonial width and vertical jaw angle position (face frontal view), and angle curvature and definition in oblique views were obtained using simplified, unbalanced Likert scales. Constructs were defined for planning 3D implant designs. The preferred jaw angle had these characteristics: 130° in face profile view, intergonial width similar to facial width, vertical position in frontal view at the oral commissure or at least not below the lower lip, jawline slope in the face frontal view nearly parallel to (with a maximum 15° downward deviation from) a line extending from the lateral canthus to the alare, ascending ramus slope 65°-75° to the Frankfort horizontal, and curvature in the oblique view visible from earlobe to chin and not pointy.

  16. David Ross, Ideal Utilitarianism, and the Intrinsic Value of Acts

    Directory of Open Access Journals (Sweden)

    Francesco Orsi

    2012-01-01

    Full Text Available The denial of the intrinsic value of acts apart from both motives and consequences lies at the heart of Ross’s deontology and his opposition to ideal utilitarianism. Moreover, the claim that acts can have intrinsic value is a staple element of early and contemporary attempts to “consequentialise” all of morality. I first show why Ross’s denial is relevant both for his philosophy and for current debates. Then I consider and reject as inconclusive some of Ross’s explicit and implicit motivations for his claim, stemming from his philosophy of action, his axiology, and his concept of intrinsic value, or a combination of these. I also criticize Ross’s later view that all right acts somehow produce some good, but that the value of some of these goods is explained by the prior rightness of the act. In the course of the discussion, the idea that acts can have intrinsic value apart from motives and consequences gains credibility both from the weaknesses in Ross’s arguments and from some putative examples. So, finally, I distinguish two attitudes in the history of ideal utilitarianism towards the necessity or not to give a detailed account of the intrinsic value of acts, and suggest that a Why Bother attitude is more promising than a Constructive one.

    Intrinsic discrete nature in thermodynamic properties of Fermi gases appears under strongly confined and degenerate conditions. For a rectangular confinement domain, thermodynamic properties of an ideal Fermi gas are expressed in their exact summation forms. For 1D, 2D and 3D nano domains, variations of both number of particles and internal energy per particle with chemical potential are examined. It is shown that their relation with chemical potential exhibits a discrete nature which allows them to take only some definite values. Furthermore, quasi-irregular oscillatory-like sharp peaks are observed in heat capacity. New nano devices can be developed based on these behaviors. - Highlights: • “Discrete behaviors” appear in thermodynamic properties of ideal Fermi gases at nano scale. • Variations of particle number and internal energy with chemical potential have stepwise behavior. • There are oscillations and peaks in the variation of heat capacity with domain size and particle number. • Fermi line and Fermi surface at nano scale are not continuous but “discrete”. • Heat capacity oscillations can be used for excess thermal energy storage at nano scale

  18. Pressurized oxy-coal combustion: Ideally flexible to uncertainties

    2013-01-01

    Simultaneous multi-variable gradient-based optimization with multi-start is performed on a 300 MWe wet-recycling pressurized oxy-coal combustion process with carbon capture and sequestration, subject to uncertainty in fuel, ambient conditions, and other input specifications. Two forms of flue gas thermal recovery are studied, a surface heat exchanger and a direct contact separation column. Optimization enables ideal flexibility in the processes: when changing the coal utilized, the performance is not compromised compared to the optimum performance of a process specifically designed for that coal. Similarly, the processes are immune to other uncertainties like ambient conditions, air flow, slurry water flow, atomizer stream flow and the oxidizer stream oxygen purity. Consequently, stochastic programming is shown to be unnecessary. Close to optimum design, the processes are also shown to be insensitive towards design variables such as the areas of the feedwater heaters. Recently proposed thermodynamic criteria are used as embedded design specifications in the optimization process, rendering it faster and more robust. - Highlights: • Proposed formulation to assess the flexibility of power generation processes facing uncertainties. • Obtained ideal flexibility of pressurized oxy-coal combustion with respect to coal type. • Performance of processes under uncertainty match performance of optimal processes for specific set of inputs. • Stochastic programming is not required and instead hierarchic optimization is utilized

    Full Text Available Lymphedema is a chronic disorder characterized by lymph stasis in the subcutaneous tissue. Lymphatic fluid contains several components including hyaluronic acid and has many important properties. Over the past few years, significant research has been performed to identify an ideal tissue to implant as a filler. Because of its unique composition, fat harvested from the lymphedema tissue is an interesting topic for investigation and has significant potential for application as a filler, particularly in facial rejuvenation. Over a 36-month period, we treated and assessed 8 patients with lymphedematous limbs who concurrently underwent facial rejuvenation with lymphedema fat (LF. We conducted a pre- and post-operative satisfaction questionnaire survey and a histological assessment of the harvested LF fat. The overall mean general appearance score at an average of 6 months after the procedure was 7.2±0.5, demonstrating great improvement. Patients reported significant improvement in their skin texture with a reading of 8.5±0.7 and an improvement in their self-esteem. This study demonstrates that LF as an ideal autologous injectable filler is clinically applicable and easily available in patients with lymphedema. We recommend the further study and clinical use of this tissue as it exhibits important properties and qualities for future applications and research.

    2015-12-01

    We investigate nonequilibrium steady states of driven-dissipative ideal quantum gases of both bosons and fermions. We focus on systems of sharp particle number that are driven out of equilibrium either by the coupling to several heat baths of different temperature or by time-periodic driving in combination with the coupling to a heat bath. Within the framework of (Floquet-)Born-Markov theory, several analytical and numerical methods are described in detail. This includes a mean-field theory in terms of occupation numbers, an augmented mean-field theory taking into account also nontrivial two-particle correlations, and quantum-jump-type Monte Carlo simulations. For the case of the ideal Fermi gas, these methods are applied to simple lattice models and the possibility of achieving exotic states via bath engineering is pointed out. The largest part of this work is devoted to bosonic quantum gases and the phenomenon of Bose selection, a nonequilibrium generalization of Bose condensation, where multiple single-particle states are selected to acquire a large occupation [Phys. Rev. Lett. 111, 240405 (2013), 10.1103/PhysRevLett.111.240405]. In this context, among others, we provide a theory for transitions where the set of selected states changes, describe an efficient algorithm for finding the set of selected states, investigate beyond-mean-field effects, and identify the dominant mechanisms for heat transport in the Bose-selected state.

    Full Text Available El cambio cultural es el resultado de procesos conservativos, reformadores y revolucionarios, destructores de viejas estructuras. El intento de preservar en el siglo XXI los ideales de la cultura del libro y de optimizar estructuras existentes por medio de la digitalización, el e-learning y la interconexión electrónica, parece algo inevitable. Sin embargo, desvía la atención de las potencialidades reales de los nuevos medios. Es necesario acuñar una comprensión fundamentalmente nueva de la comunicación, el saber y el procesamiento de la información. Pero si el nuevo aprendizaje y el nuevo pensamiento no son simplemente la continuación del modelo de aprendizaje de los últimos 500 años, y si los nuevos medios no representan sólo una mutación electrónica del libro, al tiempo que se mantienen atados al ideal de procesamiento paralelo de informaciones de baja interacción, ¿en qué puede consistir ese nuevo aprendizaje? ¿Qué aspecto deben tener las informaciones y las estrategias de pensamiento que en lo posible no pretenden validez general alguna y aun así se hacen culturalmente relevantes?.

    Full Text Available OBJETIVO: Revisar a literatura acerca da aplicação do conceito de acolhimento e elucidar as contribuições desse conceito para as práticas na atenção primária à saúde. MÉTODOS: Foi realizada uma revisão integrativa que investigou a produção do conhecimento sobre atenção primária à saúde. Foram pesquisadas as seguintes bases de dados: LILACS, SciELO e MEDLINE, no período de 2006 a 2010. Os termos de busca utilizados na LILACS E SciELO foram: "acolhimento" AND "programa saúde da família" AND "saúde". Na MEDLINE foram usados os termos "user embracement" AND "family health program" AND " health". A coleta de dados se deu no mês de novembro de 2010. RESULTADOS: Foram identificados 21 artigos que preencheram os critérios de inclusão, todos descrevendo estudos brasileiros. Os artigos foram sistematizados em três categorias empíricas: vínculo e acolhimento; processo de trabalho em atenção primária à saúde; e avaliação dos serviços. As categorias são complementares e convergem para duas visões principais de acolhimento: dispositivo capaz de reorganizar a atenção à saúde e postura perante o usuário. Percebe-se ainda o acolhimento como ferramenta de gestão em defesa do Sistema Único de Saúde, associado aos princípios da integralidade e universalidade. CONCLUSÕES: O acolhimento é capaz de promover o vínculo entre profissionais e usuários, possibilitando o estímulo ao autocuidado, melhor compreensão da doença e corresponsabilização pelo tratamento. Auxilia na universalização do acesso, fortalece o trabalho multiprofissional e intersetorial, qualifica a assistência, humaniza as práticas e estimula ações de combate ao preconceito. Entretanto, mereceria maior atenção a perspectiva do usuário sobre a utilização do acolhimento, um tópico a ser enfocado por estudos futuros.

  6. Design and control of an ideal heat-integrated distillation column (ideal HIDiC) system separating a close-boiling ternary mixture

    International Nuclear Information System (INIS)

    2007-01-01

    Despite the fact that a stand-alone ideal heat-integrated distillation column (ideal HIDiC) can be thermodynamically efficient and operationally stable, the application of an ideal HIDiC system to separate a close-boiling multi-component mixture is still a challenging problem because of the possibility of strong interactions within/between the ideal HIDiCs involved. In this work, employment of two ideal HIDiCs to separate a close-boiling ternary mixture is studied in terms of static and dynamic performance. It is found that the ideal HIDiC system can be a competitive alternative with a substantial energy saving and comparable dynamic performance in comparison with its conventional counterpart. The direct sequence appears to be superior to the indirect sequence due to the relatively small vapor flow rates to the compressors. Controlling the bottom composition of the first ideal HIDiC with the pressure elevation from the stripping section to the rectifying section helps to suppress the disturbances from the feed to the second ideal HIDiC. Special caution should, however, be taken when the latent heat of the distillates is to be recovered within/between the ideal HIDiCs involved, because a positive feedback mechanism may be formed and give rise to additional difficulties in process operation

    In this research, we wanted to clarify how gender images are different or invariant and related to parents, attributes, and the attitude of controlling life (locus of control) in two cultural contexts, Japan and Finland. For this purpose, students' ideal gender images, consisting of ideal mother, female, father and male images, and parents' similarity to the four ideal gender images were studied in 135 Japanese and 119 Finnish university students. Major findings were (a) Japanese students' ideal gender images were more stereotypic than those of Finnish students; (b) students' ideal mother image and parents' similarity to the ideal mother image were related only to their sex, which supports Jung's theory; (c) students socially learned other ideal gender images, but these did not fit with expectation from social learning theory; (d) Japanese students' mothers are models or examples of gender images, but Finnish male students did not seem to base their ideal gender images on their parents. Implication of measures was discussed.

    Over the last decade, researchers have increasingly demonstrated that ideal affect-the affective states that people value and ideally want to feel-shapes different aspects of daily life. Here I briefly review Affect Valuation Theory (AVT), which integrates ideal affect into existing models of affect and emotion by identifying the causes and consequences of variation in ideal affect. I then describe recent research that applies AVT to the valuation of negative states as well as more complex states, examines how ideal affect shapes momentary affective experience, suggests that ideal affect has both direct and indirect effects on health, and illustrates that people's ideal affect shapes how they judge and respond to others. Finally, I discuss the implications of cultural and individual differences in ideal affect for clinical, educational, work, and leisure settings. Copyright © 2017 Elsevier Ltd. All rights reserved.

  11. Identifying and addressing student difficulties with the ideal gas law

    Science.gov (United States)

    Kautz, Christian Hans

    This dissertation reports on an in-depth investigation of student understanding of the ideal gas law. The research and curriculum development were mostly conducted in the context of algebra- and calculus-based introductory physics courses and a sophomore-level thermal physics course. Research methods included individual demonstration interviews and written questions. Student difficulties with the quantities: pressure, volume, temperature, and the number of moles were identified. Data suggest that students' incorrect and incomplete microscopic models about gases contribute to the difficulties they have in answering questions posed in macroscopic terms. In addition, evidence for general reasoning difficulties is presented. These research results have guided the development of curriculum to address the student difficulties that have been identified.

In the sequence there is, for instance, a code of length 21 and dimension10with minimal distance9, and a code of length21and dimension16with minimal...... distance3. The codes are constructed from algebraic geometry using the dictionary between coding theory and algebraic curves over finite fields established by Goppa. The curve used in the present work is the Klein quartic. This curve has the maximal number of rational points over GF(2^{3})allowed by Serre...

    2012-01-01

    Immigrants typically express cravings for the food of their homeland, but for undocumented and temporarily documented Salvadoran immigrants living in the United States, the hunger for their traditional cuisine is particularly poignant. To cope with a history of food scarcity in El Salvador and their documentation liminality in the United States, Salvadoran immigrants in this study crave symbolically rich foods. Salvadoran women provide these foods by recreating for their families an ideal Salvadoran meal into which they "groom" meanings of an imagined past and a hoped for present and future. Salvadoran immigrants' cravings, more cultural than physiological, are not readily satisfied, thus contributing to the overconsumption of food and the high rate of overweight among first-generation Salvadoran-American children.

  14. Outcome Measurement in Nursing: Imperatives, Ideals, History, and Challenges

    2016-05-31

    Nurses have a social responsibility to evaluate the effect of nursing practice on patient outcomes in the areas of health promotion; injury and illness prevention; and alleviation of suffering. Quality assessment initiatives are hindered by the paucity of available data related to nursing processes and patient outcomes across these three domains of practice. Direct care nurses are integral to self-regulation for the discipline as they are the best source of information about nursing practice and patient outcomes. Evidence supports the assumption that nurses do contribute to prevention of adverse events but there is insufficient evidence to explain how nurses contribute to these and/or other patient outcomes. The purposes of this article are to examine the imperatives, ideal conditions, history, and challenges related to effective outcome measurement in nursing. The article concludes with recommendations for action to move quality assessment forward, such as substantial investment to support adequate documentation of nursing practice and patient outcomes.

    A relatively simple quasi-classical description of quantum plasmas using as first approximation the Bhatnagar-Gross-Krook (BGK) collision integral, if combined with the modern numerical simulation methods, might be effective tool of a deep study of non-ideal plasma kinetics in a variety of urgent applications as inertial confinement and cold fusion, transport and collective properties of highly condensed plasmas in liquid metals, semi- and superconductors and others. Consider one-dimensional degenerate plasma consisting of thermal electrons and thermal bosons (deuterons) in the vicinity of the equilibrium Fermi- and Bose-type distributions respectively. In the frame of our rough mixed model we solve Vlasov-BGK-Poisson eqs using simplified version of the SUR code

    Full Text Available Ready-to-drink fruit juices represent a large share of the market and are an important target for product development. The mixture of fruits can bring about improvements to nutritional and sensory aspects of these beverages while making used of the wide variety of exotic fruits from the Amazon region. Therefore, it is necessary to select mixed fruits and determine their ideal sweetness according to consumer acceptance. Consumers in the city of Belém (Brazil evaluated five different concentrations of sugar using the just-about-right scale in two blends selected by preference ranking. For the cupuassu-acerola-açai blend, the optimum concentration of sugar was 9.5 g/100 mL, and for the soursop-camucamu-yellow mombin blend, it was 10.7 g/100 mL.

    Simon, Cory M.; Smit, Berend; Haranczyk, Maciej

    2016-03-01

    Ideal adsorbed solution theory (IAST) is a widely-used thermodynamic framework to readily predict mixed-gas adsorption isotherms from a set of pure-component adsorption isotherms. We present an open-source, user-friendly Python package, pyIAST, to perform IAST calculations for an arbitrary number of components. pyIAST supports several common analytical models to characterize the pure-component isotherms from experimental or simulated data. Alternatively, pyIAST can use numerical quadrature to compute the spreading pressure for IAST calculations by interpolating the pure-component isotherm data. pyIAST can also perform reverse IAST calculations, where one seeks the required gas phase composition to yield a desired adsorbed phase composition.

  18. Compressible gas flow through idealized cracks of large aspect ratio

    International Nuclear Information System (INIS)

    Chivers, T.C.; Skinner, J.; Williams, M.E.

    1975-07-01

    Gas flow through large aspect ratio idealized cracks is considered, where isothermal conditions with choking at exit are assumed in the theoretical analysis. For smooth wall cracks, comparisons are made between experimentally determined flowrates and those predicted, and good agreement is shown. This is followed by consideration of flow through a notional crack to examine the influence of width and surface roughness. By considering flow as simply proportional to Wsup(n), the treatment shows 'n' to reduce with W increasing, but surface roughness increases 'n' over the value appropriate to smooth conditions. From these observations it is concluded that further work is required to determine:- (i) real crack geometry and its influence on any leak-before-break philosophy, and (ii) the influence of real surface roughness on flowrate.

    1995-01-01

    Calculating caloric properties from a thermal equation of state requires information such as isobaric heat capacities in the ideal-gas state as a function of temperature. In this work, values for the parameters of the c p o correlation proposed by Aly and Lee were newly determined for 21 pure gases which are compounds of natural gas mixtures. The values of the parameters were adjusted to selected c p o data calculated form spectroscopic data for temperatures ranging from 10 to 1000 K. The data sources used are discussed and compared with literature data deduced from theoretic models and caloric measurements. The parameters presented will be applied in a current GERG project for evaluating equations of state (e.g., the AGA 8 equation) for their suitability for calculating caloric properties

    Li, Yushan; Gu, Qiang

    2014-01-01

    Ultracold atomic gases can be spined up either by confining them in rotating frame, or by introducing “synthetic” magnetic field. In this paper, thermodynamics of rotating ideal Bose gases are investigated within truncated-summation approach which keeps to take into account the discrete nature of energy levels, rather than to approximate the summation over single-particle energy levels by an integral as it does in semi-classical approximation. Our results show that Bose gases in rotating frame exhibit much stronger dependence on rotation frequency than those in “synthetic” magnetic field. Consequently, BEC can be more easily suppressed in rotating frame than in “synthetic” magnetic field.
