    Full Text Available RESUMO Laser in situ Keratomileusis (LASIK é uma das técnicas mais aceitas na cirurgia refrativa atualmente. Sua previsibilidade, reprodutibilidade, segurança e baixos índices de efeitos colaterais justificam a ampla difusão dessa técnica. Trata-se de um procedimento cirúrgico a laser cujo objetivo consiste na modificação da estrutura corneana, permitindo uma mudança do ponto focal do olho. Dessa forma, é possível corrigir ametropias tais como a miopia, astigmatismo e pequenos graus de hipermetropia. A técnica do LASIK consiste na criação de um flap corneano por meio da utilização de um microcerátomo ou do laser de femtossegundo. Em seguida, é realizada a aplicação do excimer laser sobre o leito estromal com posterior reposicionamento do flap, criando-se uma interface entre as lamelas anterior e posterior da córnea. Apesar das inúmeras vantagens, existem patologias que resultam de complicações primárias da interface do flap, que podem causar confusão no momento do diagnóstico, por possuírem semelhanças quanto à sua apresentação clínica. O objetivo desse trabalho é definir, caracterizar e comparar tais entidades com intuito de facilitar o diagnóstico diferencial dessas patologias evitando a adoção de um tratamento equivocado. Como resultado do estudo, são apresentadas recomendações quanto à conduta nos casos de cada patologia de interface, com investigação por meio da anamnese e exame clínico, a fim de permitir diagnóstico diferencial entre as principais entidades primárias da interface do procedimento LASIK.

    Full Text Available A cultura ocidental fragmentou o corpo em redutoras perspectivas teóricas que fizeram aparecer diferentes ordens de realidade: biológica, psíquica e social. Este artigo identifica o limite da biomedicina em integrar a alteridade no conceito de doença, como uma das lacunas importantes para a aproximação entre os conceitos de psiquismo e corpo biológico. Apresenta a proposição de que as interfaces do corpo são centrais para a compreensão da constituição do corpo biológico em seus processos de individuação. Levanta a possibilidade de ocorrer uma transformação epistemológica na medicina, a partir da valorização dos estudos sobre fenômenos biológicos que ocorrem nestas interfaces. Ressalta, mediante análise da literatura médica recente, indícios de uma possível integração da alteridade no conceito de doença. Esta análise se detém na crescente elaboração de um discurso sobre a relação com os microorganismos e sua importância na constituição ontogênica do organismo humano e, por conseqüência, na etiologia das doenças.Western culture has fragmented the body into a restrictive theoretical perspective that gave rise to different reality orders: biological, psychic and social. This article identifies the limits of biomedicine for integrating alterity into the concept of disease, as one of the relevant gaps for the approximation between the concepts of psyche and the biological body. It presents the proposition that the body interfaces are crucial for the understanding of the constitution of the biological body in individuation processes. It raises the possibility that there may be an epistemological transformation in medicine, based on the value that studies place on the biological phenomena that take place in these interfaces. It emphasizes, upon the analysis of recent medical literature, indications of a possible integration of alterity into the concept of disease. This analysis delves into the growing design of

    Full Text Available Este trabalho ilustra uma pesquisa interdisciplinar sobre os usuários e as interfaces de sistemas de gestão da informação, levando em consideração a ergonomia cognitiva, o design emocional, o processo de desenvolvimento e avaliação das interfaces de sistemas da informação, o custo, a praticidade, a disponibilidade, a acessibilidade e a usabilidade da informação. A proposta interdisciplinar incorpora contribuições da Ciência da Informação, Artes, Comunicação, Psicologia Cognitiva, Educação, Computação e áreas afins. Para alcançar este objetivo têm sido realizadas diversas experiências nas quais têm sido considerados certos atributos subjacentes à atuação do usuário, tais como, motivação, raciocínio, atenção e memorização. Muitas vezes um sistema de informação é conhecido pelos usuários quando este já está em funcionamento, isto que pode gerar a existência de uma discrepância entre as necessidades e expectativas dos usuários e as dificuldades encontradas para acessar à informação. Esta pesquisa avalia o processo de desenvolvimento de interfaces de sistemas de gestão da informação desde o início, integrando o usuário e sua maneira de entender e executar a tarefa, com a utilização e aplicação de técnicas tais como, a prototipagem em papel, o grupo focal, a entrevista, o arranjo de cartões, a observação sistemática, a análise da tarefa e da atividade. Isto gerou recomendações fundamentadas na junção da lógica dos usuários, dos projetistas e dos profissionais da informação, sendo revisada a literatura sobre a área, as publicações que agrupam recomendações, e analisados os resultados de avaliação da usabilidade em diferentes experiências. A aplicação dessas recomendações têm agregado valor à compreensão e análise dos aspectos envolvidos na concepção de interfaces de sistemas de gestão da informação e ao aumento no grau de satisfação dos usuários

    Full Text Available O presente artigo resgata inicialmente as formas, conteúdo e projeção operacional da vigilância epidemiológica como instrumento indispensável para o campo do saber e práticas da saúde pública. Em seguida, verificamos que o modelo de vigilância da saúde estabelece uma ampliação desse conceito operacional de vigilância, ao integrar as práticas coletivas e individuais em diferentes dimensões das necessidades de saúde, que incluem além do controle de riscos e danos, os determinantes ecossociais. Na sequência, buscamos dimensionar os distintos níveis de atuação desta prática sanitária articulados às intervenções de promoção, proteção e recuperação, sob uma lógica regionalizada e integralizada do Sistema Único de Saúde brasileiro. Por fim, argumentamos que todo o arcabouço conceitual-operacional de vigilância da saúde se constitui como uma base política e sanitária para a consolidação do paradigma da promoção da saúde no campo da Saúde Coletiva.The present article rescues initially the forms, content and operational projection of the epidemiological surveillance as indispensable tool for the knowledge field and public health practices. After that, we verify that the health surveillance model establishes an enlargement of this operational concept of surveillance by integrating the collectives and individuals practices in different health necessities dimensions, which includes beyond of the risks and damages control also the eco-socials determinants. In the sequence, we search to dimension the distinct levels of actuation of this sanitary practice articulated to the interventions of promotion, protection and recovery under a located and integrated logic of the unique system of Brazilian health. Finally, we argue that all the conceptual-operational model framework of public health surveillance itself constitutes as a politics and sanitary base for the consolidation of the health promotion paradigm in the

    Full Text Available The Brazilian coastal zone extends from 4º N to 34º S latitude and because of its long extension, the interface zone from continent to ocean includes a high diversity of geomorphologic and oceanographic characteristics. The rivers from the Northeast and East regions are marked by a typical unimodal seasonal flux patterns but with different amplitudes. As the climate indicates, the rivers from the Northeast are subject to an accentuated seasonal variability with an elevated input and flood pulses during the rainy season and low to negligible fluxes during the dry season. Small-scale rivers usually present typical torrential behaviour. In the humid eastern region, the unimodal seasonal cycle is dampened with a more constant input supply. Recently, some studies have shown that the material supply from rivers along the Northeast and Eastern coasts is diluted by surface tropical waters of oceanic currents and that the estuarine plume dispersal is restricted to a narrow coastal belt. However, human impacts of course mask or even override both natural hydrological cycles and CO2 emissions from terrestrial biomes, or depending on the nature of the human impact, can even increase extreme events. Henceforth this contribution addresses the typological, hydrological and biome diversity of the four estuarine systems fed and affected by the respective Amazon, São Francisco, Paraíba do Sul and Plata watersheds.A zona costeira brasileira se estende de 4º N a 34º S de latitude. Por causa de sua longa faixa de zona de interface do continente com o oceano, é encontrada uma grande diversidade nas características geomorfológicas e oceanográficas. Os rios das regiões nordeste e leste mostram um padrão de fluxo sazonal normalmente unimodal, mas diferentes em amplitude. Conforme o clima indica, os rios do nordeste estão sujeitos a uma acentuada variabilidade sazonal, com elevação da vazão em forma de pulsos de inundação durante a estação chuvosa e

    Full Text Available I have investigated, through the lens of the Complexity Paradigm, aligned with the premises of the Theory of General Systems and the concept of affordances, two virtual learning environments (VLEs, defining them as systems composed of digital genres, regarding a VLE as a complex adaptive system. These VLEs were reconfigured from the platforms TelEduc and Moodle and used to teach the discipline "Digital Literacy", in the course of Languages and Literature Teaching degree at the Federal University of Minas Gerais (UFMG, during the second semester of 2007 and the second semester of 2008, respectively. The analyses have indicated that the textual production of the emerging online discourse communities was influenced by the coupling of different layers of the interface, the textual genres and the communicative and pedagogical purposes and, also, by the affordances which were perceived and acted upon by teachers and learners. The analyzed VLEs have portrayed the characteristic of equifinality, regardless of the possibilities and constraints offered by the platforms TelEduc and Moodle.Investigo, através da lente do Paradigma da Complexidade, juntamente com os pressupostos da Teoria Geral dos Sistemas e do conceito de affordances, dois ambientes virtuais de aprendizagem (AVAs, definindo-os como sistemas compostos por gêneros digitais, partindo do pressuposto de que um AVA é um sistema adaptativo complexo. Esses AVAs foram reconfigurados a partir das plataformas TelEduc e Moodle e utilizados para ministrar a disciplina "Letramento Digital", no curso de Letras da Universidade Federal de Minas Gerais (UFMG, nos semestres 2007-2 e 2008-2, respectivamente. As análises indicam que a produção textual das comunidades discursivas on-line emergentes nos AVAs foi influenciada pelo acoplamento aninhado de camadas distintas da interface, dos gêneros textuais e dos propósitos comunicativos e pedagógicos, e, ainda, pelas affordances percebidas e efetivadas

    Full Text Available O objetivo deste trabalho foi mostrar os diferentes padrões micromorfológicos da interface adesiva que podem ser encontrados em fragmentos de um mesmo espécime em função da variação de fatores durante o processamento dos mesmos para análise em MEV. Para isso, cilindros de resina foram cimentados na dentina da superfície oclusal de terceiros molares inclusos recém-extraídos e posteriormente seccionados longitudinalmente para observação no MEV. Os resultados obtidos indicaram uma grande variação no direcionamento e comprimento dos "tags". Isso indica a necessidade de uma padronização dos sítios de dentina, angulação de seccionamento dos espécimes e escolha de fragmentos a serem visualizados, a fim de evitar possíveis erros de interpretação ao se analisar a eficiência da penetração dos sistemas adesivos.

    Full Text Available OBJETIVO: Realizar estudo experimental para a avaliação histomorfométrica da interface óssea dos parafusos expansores utilizados no sistema de fixação anterior da coluna cervical. Métodos: Foram utilizadas no estudo cinco vértebras cervicais de ovelhas (C4, nas quais os parafusos foram inseridos. O parafuso expansor de 18,5mm de comprimento e 5,0mm de diâmetro externo (Ulrich foi inserido em ambos os lados da véterbra C4. No lado esquerdo o parafuso era inserido sem o parafuso interno de expansão e, no lado direito, com o parafuso de expansão interna. Na porção inferior da vértebra foi confeccionado o orifício-piloto com broca de 2,5mm sem a introdução de implante. A região da vértebra contendo os parafusos e o orifício-piloto foi preparada para estudo histológico da interface dos implantes e o tecido ósseo da parede do orifício-piloto. Por meio do estudo histomorfométrico foi avaliada a densidade óssea total, a densidade óssea externa (fora da rosca do parafuso, a densidade interna (dentro da rosca do parafuso e a medida linear de contato entre o tecido ósseo e o implante. RESULTADOS: A densidade óssea total foi maior no grupo I (parafuso expandido em relação ao grupo III (controle. A densidade óssea externa foi maior nos grupos I (parafuso expandido e II (não expandido em relação ao grupo III. A densidade interna foi maior no grupo I em relação aos grupos II e III e maior no grupo II em relação ao grupo III. O contato linear foi maior no grupo I em relação aos grupos II e III. CONCLUSÃO: As alterações da estrutura do tecido ósseo ao redor dos parafusos expansores, detectadas imediatamente após a sua aplicação, forneceram subsídios para o entendimento da maior resistência ao arrancamento desses implantes, que poderiam estar relacionadas com a compactação do osso esponjoso ao redor do mesmo, proporcionando maior área de contato entre o implante e o tecido ósseo.OBJECTIVE: To perform an

    Full Text Available Este trabalho objetiva, primeiramente, evidenciar a utilidade da CFG e da FCFG no estudo da sintaxe formal. A aplicação de parsers baseados nesses formalismos na análise de um corpus pode revelar consequências de uma dada análise que de outro modo passariam despercebidas. O NLTK é uma caixa de ferramentas para o PLN em Python que possibilita a construção de parsers em diferentes arquiteturas. No entanto, para uma utilização não trivial dessa biblioteca na análise sintática automática são necessários conhecimentos de programação. Para permitir o acesso de não programadores à implementação e testagem de parsers, desenvolvemos o Donatus, uma interface gráfica amigável para as facilidades de parsing do NLTK, dotada de recursos adicionais que a tornam interessante também para programadores. Como exemplo do funcionamento da ferramenta e demonstração da sua relevância na investigação sintática formal, comparamos implementações de duas análises alternativas da modificação adjetival em português. A primeira abordagem, baseada na Teoria X-barra tradicional, produziu um grande número de pseudoambiguidades. Esse problema foi evitado por um parser baseado em abordagem no âmbito do Programa Minimalista. Sem o recurso do computador, essa diferença entre as duas abordagens não seria facilmente revelada.

    Full Text Available As redes sociais tem se destacado, entre outros, por incentivarem o usuário a produzir conteúdo. Ambientes corporativos e acadêmicos tem buscado explorar esse potencial, criando redes sociais temáticas ou corporativas, onde pessoas e grupos se comunicam de forma similar às redes sociais massivas, mas de forma independente. Uma das plataformas livres mais utilizadas para construção destas redes sociais é o Oxwall. Assim, este artigo apresenta a análise da interface padrão do Oxwall com base no framework Reader to leader, que considera tanto aspectos de usabilidade, quanto de sociabilidade – crucial para promover a participação do usuário. A análise aponta que a interface padrão da plataforma contém elementos que incentivam a participação dos usuários nos níveis de leitor e contribuidor. Contudo, carece de fatores que estimulem usuários a atingirem níveis mais altos de interação e produção de conteúdo, como os colaboradores e líderes.

    Full Text Available O estudo objetivou avaliar a resposta da assembleia de formigas que nidificam na interface solo-serapilheira a um gradiente de alteração ambiental. O estudo foi realizado em três ambientes com diferentes usos do solo: fragmento florestal, sistema agroflorestal (SAF e pastagem situados em região de domínio da mata atlântica no sudeste do Brasil. Em cada ambiente foram demarcadas 10 parcelas de 1 m² e todos os ninhos de formigas encontrados foram registrados. Foram encontrados 215 ninhos (103 no fragmento florestal, 64 no sistema agroflorestal e 48 na pastagem, de 31 espécies. O número acumulado de espécies foi maior no fragmento florestal que na pastagem, mas não diferiu do SAF. A composição de espécies foi diferente entre o fragmento florestal e os outros dois ambientes. A riqueza média de espécies de formigas por parcela foi maior no fragmento florestal e menor na pastagem. A quantidade de serapilheira não foi um fator importante para as diferenças na riqueza de espécies. Atividades humanas que reduzam a heterogeneidade da vegetação alteram a composição e diminuem a riqueza de espécies das assembleias de formigas.

    2014-09-01

    Full Text Available Há crescente interesse e emprego de procedimentos metodológicos característicos da pesquisa qualitativa por diversas áreas do conhecimento que tradicionalmente não eram comuns. Na área da saúde, é reconhecida a importância da pesquisa qualitativa para a compreensão dos processos saúde-doença. Sua credibilidade tem sido questionada em vários âmbitos e relacionada a usos negligentes da abordagem qualitativa, como reduzir a relevância teórico-metodológica à aplicação de técnicas. O mau uso é mais frequentemente notado nas publicações quando a abordagem qualitativa é utilizada enquanto um kit de ferramentas. Simultaneamente, o “produtivismo” exigido pelas instituições tem obrigado os pesquisadores a rever objetivos mais amplos de análise/escrita. O olhar sobre um grupo/contexto requer um aparato teórico-metodológico, de modo a possibilitar inferir algo e propor rupturas teóricas e/ou evidenciar novos pontos sobre um tema conhecido.

    Full Text Available Objetivou-se investigar as crenças dos profissionais de saúde e de direito sobre o aborto induzido, por meio da pesquisa qualitativa. Para tanto, foram entrevistados 15 profissionais de saúde (médicos ginecologistas/obstetras, enfermeiros e psicólogos e 10 profissionais de direito (promotores de justiça e juízes de direito. As entrevistas foram operacionalizadas com base em categorias determinadas a partir dos sentidos suscitados, processados em uma série de etapas. Dessa forma, os discursos dos participantes foram agrupados em duas categorias: atitude e aspectos jurídicos. A categoria atitude foi composta por crenças contrárias e favoráveis a essa prática, que se centraram na heteronomia e sacralidade da vida. As crenças favoráveis, por sua vez, estiveram ancoradas na perspectiva dos direitos reprodutivos e sexuais, na redução de riscos e danos e na autonomia da mulher sobre seu próprio corpo. Em relação aos aspectos jurídicos, verificou-se que os profissionais de direito apresentaram um posicionamento mais rígido quanto à punição das mulheres que abortam. Embora se tenha uma legislação sobre o assunto e normas técnicas de atenção humanizada ao aborto, as discussões não se encerram no ponto de vista jurídico ou deontológico; ao contrário, abrangem um leque variado de crenças, as quais podem guiar a atuação dos profissionais, tanto no cuidado à saúde da mulher como na interpretação dos seus direitos.

Estudo de abordagem qualitativa, descritivo, desenvolvidos com diferentes atores sociais que integram o processo de formação profissional e laboral da área da saúde em um município do Rio Grande do Sul. Os dados foram coletados por meio de entrevista semiestruturada com questões norteadoras sobre o objeto de estudo, feita com trabalhadores hospitalares, enfermeiros, docentes, acadêmicos da área da saúde e agentes comunitários de saúde. Cada subprojeto foi analisado individualmente, com base no referencial sobre análise de conteúdo. Os resultados evidenciam que os sujeitos possuem visões dicotômicas sobre meio ambiente e reconhecem os efeitos prejudiciais da atual crise ambiental, alegando que o ser humano é o principal causador. Os sujeitos do estudo entendem que há estreita interface entre saúde e meio ambiente, sendo as populações menos privilegiadas economicamente as mais afetadas pelos danos ambientais. Conclui-se que o aprofundamento do debate sobre o tema no processo de formação e prática profissional em saúde é fundamental no sentido de se buscar a efetiva responsabilidade socioambiental por parte dos atores sociais atuantes no setor.This article presents the view health area professionals and students have concerning the interface between health and the environment.

    Full Text Available Nas últimas décadas, assistimos à revitalização do debate em torno da agricultura familiar pela incorporação das discussões sobre as múltiplas funções da agricultura num rural que não pode mais ser visto como domínio exclusivo da atividade agrícola e dos agricultores. No contexto brasileiro, acreditamos que essa discussão deva ser permeada pela análise de como processos diferenciados de distribuição fundiária e desenvolvimento econômico e o tipo de agricultura resultante geram ruralidades específicas com características como, no caso da agricultura familiar, a manutenção de práticas sociais e de trabalho marcadas pelas relações de parentesco e vizinhança presentes numa sociedade de interconhecimento. Partindo desse princípio, este trabalho analisa a agricultura familiar de um bairro rural do município de Ouro Fino - MG, sua herança histórica e sua participação na criação de uma paisagem natural e humana que muito contribui para a atratividade da região.The last decades witnessed the revitalization of the debate around family farming with the addition of discussions regarding the multiple functions of agriculture, given the fact that rural areas are longer devoted exclusively to agricultural activities. In the Brazilian context, we believed that this debate must be permeated by analyses of how differentiated processes of land distribution and economic development, and the resulting types of agriculture, generate specific ruralities with characteristics such as, in the case of family farming, the maintenance of social and work practices marked by the relations among relatives and neighbours. It is in this light that this research analyses family agriculture in a rural area of Ouro Fino-MG, its historical heritage, and its participation in the creation of a physical and human landscape that greatly contributes to the attractiveness of the region.

    Full Text Available No final da década de 1980 alguns países da Europa bem como o Japão e os Estados Unidos iniciaram pesquisas para o desenvolvimento de modelos de TV digital. No Brasil, somente em 2003 após publicação do Decreto 4.901, começou o desenvolvimento de pesquisas visando a construção do Sistema Brasileiro de Televisão Digital (SBTVD que dentre outros objetivos deveria promover a inclusão social e a formação de uma rede de educação a distância. A TV digital é considera por alguns autores como uma nova mídia, pois ela traz características do computador e da televisão. Desta forma esta nova mídia pode facultar novas formas de comunicação, de produção de conteúdos e de interatividade, o que para a área da educação são aspectos de fundamental importância, uma vez que até o momento com a televisão analógica não há possibilidades de construção de conteúdos colaborativos tanto pelo fator tecnológico quanto principalmente pelo fator político centralizador das produções disponíveis hoje. Nesse texto analisamos alguns aspectos da implantação da TV digital em Portugal e no Brasil bem como as possibilidades de utilização do Serviço de Apoio ao Professor em Sala de Aula (SAPSA desenvolvido pela Fundação Centro de Pesquisa e Desenvolvimento em Telecomunicações (CPqD. Como resultado deste trabalho, constatamos a potencialidade da TV digital na formação de redes de colaboração necessárias para o desenvolvimento da educação. Neste sentido, percebemos que cabe igualmente aos responsáveis pelos sistemas de educação e a nós educadores evidenciarmos que queremos uma TV digital que possibilite a construção de redes colaborativas capazes de potencializar a interconexão entre educação, culturas e conhecimentos.AbstractAt the end of the 80’s, some European countries as well as Japan and the United States started researches for the development of digital tv models.

    Many operations and procedures in the petroleum industry are related to the immiscible displacement of a fluid by another one, as the secondary recovery of petroleum and pumping operation through pipelines of high viscosity oils. In this context, an stability analysis of the water-oil interface as well as of the factors that leads to the appearance of the viscous fingering phenomenon, represented by the viscous flowing of one phase that penetrates inside of the other one in the form of one or more fingers, is of major importance for the forecast, simulation and control of operations involving this kind of system. From the theories of perturbation and unstable immiscible displacement of fluids, initially conceived for cells of parallel slabs (Hele-Shaw), the authors intend to extend the concepts and adapt the criteria for the three-dimensional geometry in macroscopic scale.

    Full Text Available A partir de pesquisa bibliográfica, este texto evidencia, teoricamente, por vias fenomenológicas e ontológicas, como as idéias principais do Socialismo Utópico de Fourier estão presentes nos princípios da Economia Solidária. A situação sócio-econômica da sociedade contemporânea, centrada no consumismo e na competitividade, tem gerado restrições, tanto para a economia capitalista quanto para a maioria dos indivíduos. É, pois, em tempos de crise, que a Economia Solidária aparece como resposta às desigualdades e injustiças inerentes ao sistema capitalista, pois, privilegia, além da dimensão econômica, as esferas social e ambiental. Esta tendência não fragmentada de vida foi pensada no passado e vem ocorrendo – ainda que de modo limitado – nos dias atuais. Para evidenciar tal entendimento, ao longo do trabalho são resgatadas características do pensamento de Fourier que, hoje, aparecem fortemente vinculadas ao construto da Economia Solidária. O exercício procedido evidencia a vitalidade dos ideais do socialismo utópico na atualidade.

    Full Text Available Silicon nitride is a covalent ceramic material of high corrosion resistance and mechanical stability at elevated temperatures. Due to these properties, its use in metallurgical processes, such as the casting of alloys, is increasing. Therefore, the characterization of the interface between Si3N4 and the casted metal is of great importance to investigate possible interactions, which might deteriorate the ceramic mould or contaminate the metal. In this work, the use of Si3N4 as crucible material for Al-casting has been studied, by investigating the corrosion attack of liquid Al at a temperature of 1150 ºC during 30 days in air. The interface was characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. It has been found that due to superficial oxidation two oxide layers form - SiO2 on Si3N4 and Al2O3 on Al - which effectively hinder further reactions under the conditions studied, confering high corrosion resistance to the Si3N4 crucible.Nitreto de silício (Si3N4 é um material cerâmico covalente de elevada resistência à corrosão e estabilidade mecânica em temperaturas elevadas. Devido a essas propriedades, sua utilização em processos metalúrgicos, tais como em fundição de ligas metálicas, é crescente. Desta forma, a caracterização da interface entre Si3N4 e metais fundidos é de grande interesse para investigar possíveis interações as quais poderão deteriorar o material cerâmico e/ou contaminar o metal. Nesse trabalho o uso de Si3N4 como material base de cadinhos para fundição de alumínio foi estudado, pela investigação do ataque corrosivo de Al líquido a 1150 ºC durante 30 dias, ao ar. A interface foi caracterizada por difração de raios X, microscopia eletrônica de varredura e espectroscopia de energia dispersiva. É encontrado que devido à oxidação superficial dois óxidos se formam - SiO2 no Si3N4 e Al2O3 no Al - os quais evitam possíveis reações sob as condi

    Full Text Available O presente artigo propõe-se a narrar as experiências do início do trabalho da Psicologia na Defensoria Pública do Estado de São Paulo. Pretende-se, a partir de alguns casos encaminhados e de situações cotidianas no ambiente de trabalho, desenvolver reflexões críticas acerca das demandas endereçadas - tanto por parte dos usuários como dos outros profissionais -, de respostas possíveis e de colocar em análise o lugar que a Psicologia está sendo chamada a ocupar. Para tanto, uma ferramenta importante que se faz necessária é a análise de implicações, proposta pela análise institucional, em especial por René Lourau. Observa-se que as demandas se dividem em resoluções extrajudiciais de conflitos, apoio e encaminhamento para a rede de serviços municipais ou para acompanhamento psicológico. O desafio, na prática, é dirigir um olhar diferenciado a partir da compreensão das produções socio-histórico-econômico-familiares do sujeito de maneira a não reproduzir sofrimentos e opressões; é constantemente colocar-se como profissional envolvido na promoção da cidadania e na autonomia e no empoderamento dos sujeitos, é, em uma perspectiva ética, entender a nossa atuação como produtora de demandas, de verdades, de mundos.

    Full Text Available Este artigo defende a tese de que o minimalismo substantivo assumido por Chomsky nos desenvolvimentos recentes do programa de pesquisa em Sintaxe Gerativa abre uma perspectiva interessante para o tratamento das relações entre a sintaxe e a semântica. A concepção de ciência adotada na história desse projeto norteou a formulação de um modelo de gramática no qual a propriedade do deslocamento de constituintes tem papel central. O estudo das características dessa propriedade demonstra que os sistemas concepto-intencionais da mente humana distinguem entre diferentes tipos de relações semânticas e impõem exigências sobre o modo como essas relações são marcadas na sintaxe.This article claims that substantive minimalism, as assumed by Chomsky in the recent developments of the Generative Syntax program, opens a new perspective for the treatment of the Syntax-Semantics Interface. We first characterize the scientific view supporting the Generative model of grammar. The movement metaphor, proposed in order to capture the property observed in human languages that some constituents seem to occupy two different positions in the sentence structure at the same time, reveals that the conceptual-intentional system of the human mind distinguishes among different kinds of semantic relations marked by different mechanisms in the Syntax.

Os avanços e desafios do processo são abordados enquanto categorias de análise. A Política Nacional de Alimentação e Nutrição (PNAN foi mencionada como articuladora entre os dois campos, sendo descentralizada por uma rede com atuação nos estados e municípios. No entanto, registraram-se dificuldades políticas, institucionais e operacionais para que a PNAN possa ser efetiva no Sistema Único de Saúde e assim contribuir para o avanço da SAN no país. O predomínio do modelo biomédico, curativo e de alta complexidade foi referido como o principal impeditivo, conferindo ainda às políticas de promoção da saúde, como a PNAN, uma posição secundária em termos da sua priorização.

  17. Autogestão e subjetividade: interfaces e desafios na visão de especialistas da ANTEAG, UNISOL e UNITRABALHO

    Directory of Open Access Journals (Sweden)

    Fernanda Mitsue Soares Onuma

    Full Text Available A Administração, em sua corrente teórica dominante, tem se prestado a transformar as empresas em espaços de propagação ideológica acerca de formas hierarquizadas de organização e gestão do trabalho. Negando esta dimensão política e ideológica da ação administrativa, a Teoria da Administração tem se tornado cúmplice dos interesses do business, educando profissionais cujas ações acabam sobrepondo o econômico ao fator humano e às questões éticas. Em contraposição a este cenário de injustiça e exploração, encontra-se a autogestão, forma de gestão não hierarquizada e democrática cuja implantação tem enfrentado muita dificuldade. Para buscar compreender os desafios que se impõem aos trabalhadores e trabalhadoras que se propõem a trabalhar de maneira autogestionária, foram realizadas entrevistas semi-estruturadas com um especialista em cada uma das três seguintes entidades de fomento a organizações autogestionárias: ANTEAG, UNISOL e UNITRABALHO. Os dados foram analisados por meio do método de análise de conteúdo e indicaram que a autogestão, na visão destes profissionais, implica necessidade de uma mudança de subjetividade desses trabalhadores e trabalhadoras, acostumados ao modelo de trabalho hierarquizado e não democrático. Com base nisso, argumenta-se que, para uma melhor compreensão da dificuldade de implantação da autogestão nas organizações, é necessária a adoção de um conceito de subjetividade que englobe não só o seu caráter individual, mas também seu caráter coletivo. Conquanto a visão da subjetividade individual e coletiva nos leve a refletir sobre o fato de que os desafios da prática da autogestão são mais profundos do que aparentam inicialmente, acreditamos que sua resolução pode estar mais próxima de nós do que imaginamos.

    Full Text Available Estudos internacionais mostram que a Atenção Primária à Saúde (APS realiza a maioria dos atendimentos psiquiátricos, pois, mesmo nos países que mais investem em saúde mental, existe uma lacuna entre a oferta e a demanda por serviços especializados. No Brasil, preconiza-se que a Estratégia de Saúde da Família (ESF assista aos pacientes com problemas de saúde mental e o apoio matricial é uma ferramenta para qualificar esse trabalho. Objetivamos conhecer o perfil epidemiológico dos usuários atendidos conjuntamente por uma equipe de ESF e sua equipe matriciadora de Saúde Mental, durante dois anos, por meio da revisão dos prontuários desses pacientes. De um total de 203 atendimentos realizados nesse período, 74% eram de mulheres entre 50 a 59 anos (33%; os diagnósticos mais comuns foram Episódio Depressivo Maior (61%, Transtorno de Ansiedade Generalizada (33%, Esquizofrenia e Transtorno de Estresse Pós-Traumático (11% cada. Trinta e cinco por cento dos pacientes foram encaminhados, sendo a maioria para psicoterapia (94% e o restante para um ambulatório secundário de Saúde Mental (6%. Os psicofármacos mais prescritos foram os inibidores seletivos da recaptação da serotonina (76%, anti-histamínicos (37%, benzodiazepínicos (37% e antipsicóticos típicos (26%. Esta interface representou um acesso facilitado e eficaz para o usuário com transtorno mental de maior gravidade/complexidade e abriu portas para a integralidade da atenção e a interdisciplinaridade no trabalho cotidiano.International studies show that the Primary Health Care (PHC held the majority of psychiatric care, because even in countries that invest more in mental health, there is a gap between supply and demand for specialist services. In Brazil, it is recommended that the Family Health assist patients with mental health problems and the support matrix is an important instrument to qualify this work. We aim to know the

    Full Text Available Este trabalho visou a comparar o potencial energético de resíduos produzidos no beneficiamento de grãos de café (Coffea canephora var. Conilon e no processo de fresamento da madeira, sugerindo seu uso em substituição ao da lenha de eucalipto, no processo de secagem de grãos de café. O uso destes resíduos agrícola e florestal pode contribuir para a redução de problemas ambientais relacionados com a contaminação do solo, ar e água, devidos a seu descarte inadequado, e para reduzir os custos de produção e, ou, beneficiamento do café. Os subprodutos da destilação seca e o carvão vegetal dessas matérias-primas foram quantificados e comparados. De acordo com os resultados, pôde-se verificar que os resíduos de casca de café proporcionaram uma boa produção de carvão vegetal, visto que seu rendimento gravimétrico em carvão foi estatisticamente superior ao da lenha. Considerando a produtividade e qualidade do carvão vegetal, o melhor resultado foi obtido pela carbonização da casca de café nas temperaturas de 350 ºC a 550 ºC e dos resíduos da fresa de madeira a 550 °C, principalmente, graças aos rendimentos médios em carbono fixo, que, nesses casos, superaram aqueles apresentados pelos carvões derivados de lenha do eucalipto. Em se tratando do poder calorífico superior, verificou-se que os resíduos da fresa de madeira e os resíduos de casca de café poderão ser utilizados para secagem de grãos de café, visto que apresentaram valores de poder calorífico superior (PCS muito próximo aos de lenha de eucalipto. Graças aos bons rendimentos gravimétricos e rendimentos em carbono fixo, os carvões vegetais derivados dos resíduos produzidos no beneficiamento de grãos de café e no processo de fresamento da madeira apresentaram potencial considerável para serem utilizados como insumo energético.

    Full Text Available The clinical success of resin bonding procedures for indirect ceramic restorations and ceramic repairs depends on the quality and durability of the bond between the ceramic and the resin. The quality of this bond will depend upon the bonding mechanisms that are controlled in part by the surface treatment that promote micromechanical and/or chemical bonding to the substrate. The objective of this review is to correlate interfacial toughness (K A with fracture surface morphological parameters of the dental ceramic-resin systems as a function of ceramic surface treatment. This analysis is designed to identify mechanisms that promote adhesion of these ceramic-resin systems and an appropriate bond test method to yield relevant adhesion performance data.O sucesso clínico de procedimentos adesivos para restaurações cerâmicas e reparo destas restaurações depende da qualidade e durabilidade da adesão entre a cerâmica e a resina. A qualidade desta adesão dependerá dos mecanismos adesivos que são controlados em parte pelo tratamento de superfície que promove uma união micro-mecânica e/ou química com o substrato. O objetivo desta revisão é correlacionar a tenacidade de fratura aparente da interface adesiva (K A com os parâmetros morfológicos da superfície de fratura de sistemas cerâmica-resina em função do tratamento da superfície cerâmica. Esta análise é desenvolvida para identificar os mecanismos que promovem a adesão nestes sistemas cerâmica-resina e uma metodologia apropriada para testar a resistência adesiva produzindo resultados relevantes da performa adesiva.

    Renata Castelo Peixoto

    Full Text Available O artigo propõe uma reflexão psicolingüística sobre as construções conceituais de crianças surdas no que diz respeito à escrita. O trabalho revela, a partir de um diálogo com as idéias de Emília Ferreiro e Ana Teberosky, que a psicogênese da escrita vivenciada por crianças surdas, que têm a língua de sinais como primeira língua e língua de instrução, se desenrola de forma diferente ao que é vivido por crianças ouvintes em processo inicial de construção da escrita. As principais especificidades dessa aquisição relacionam-se: a não-fonetização da escrita, a uma intensa exploração dos aspectos viso-espaciais da escrita e ao uso dos parâmetros fonológicos da língua de sinais como elemento regulador e organizador da escrita. Tais peculiaridades exigem, portanto, que a escola e o professor alfabetizador revejam suas concepções sobre o processo de escrita no surdo, pensando em (novas práticas pedagógicas que considerem a realidade bilíngüe e sua relação não-sonora com a escrita.

    Full Text Available Um modelo foi desenvolvido com o objetivo de simular as dinâmicas de Nitrogênio e Fósforo pela suinocultura gaúcha associadas às produções de milho e soja do Rio Grande do Sul. O modelo é constituído por um submodelo animal (SMA e outro vegetal (SMV. Os princípios gerais do SMA foram baseados em sistemas tecnológicos (ST, categorias animais, concentrações de N e P das dietas e suas eficiências digestiva e metabólica. O SMA integra três níveis de agregação, sendo constituído de 10 compartimentos para N e P e 300 subcompartimentos relacionados aos ST e às categorias animais. Os dados da suinocultura gaúcha foram divididos em sete mesorregiões de acordo com as definições fisiográficas. Os ST foram definidos pelo número de suínos terminados/porca/ano. O SMV é constituído pelos subcompartimentos milho e soja. Os parâmetros do SMV foram baseados nas áreas cultivadas e nas produções de milho e soja de cada município. De acordo com o balanço entre a produção e o consumo, todas as mesorregiões possuem excedente de milho e soja. O consumo anual de milho e farelo de soja pela suinocultura gaucha é em média de 1,14 e 0,39 milhões de toneladas, respectivamente. O volume anual de N e P ingeridos pelos suínos é de aproximadamente 36 e 5,7 mil toneladas. Desse volume, cerca de 41% do N e 71% do P retornam ao meio ambiente. Os valores simulados dos diferentes cenários de oferta/demanda de milho e soja no Rio Grande do Sul mostram autosuficiência das sete mesorregiões. Os fluxos de nutrientes entre solo-planta-animal-solo simulados mostram que as mesorregiões do Rio Grande do Sul têm níveis de nitrogênio e fósforo lançados ao meio ambiente pelos suínos abaixo dos limites determinados pela União Europeia. O modelo simula adequadamente as transferências de N e P entre as interfaces animal e vegetal na produção suína, no Rio Grande do Sul.A model was developed to simulate the Nitrogen and Phosphorus dynamics

O Relatório 2000 trouxe à agenda da OMS o comprometimento com os objetivos louváveis de avaliação dos sistemas de saúde, monitoramento das desigualdades em saúde e alcance da equidade no financiamento da saúde. Entretanto, o instrumental utilizado foi exposto a inúmeras críticas, tanto de cunho metodológico como conceitual. Como parte deste processo, para suprir informações sobre o estado de saúde das populações, a OMS propôs a elaboração da Pesquisa Mundial de Saúde (PMS em vários países membros. No Brasil, a PMS foi conduzida no ano de 2003, e objetivou estabelecer parâmetros consistentes para avaliar o estado de saúde da população e a assistência prestada de acordo com as expectativas da população usuária, além de mensurar as desigualdades socioeconômicas em saúde. O inquérito foi realizado em 5000 indivíduos com 18 anos e mais de idade, em âmbito nacional. A amostragem foi realizada em três estágios. No primeiro, foram selecionados 250 setores censitários, com probabilidade proporcional ao tamanho. Em cada setor, foram selecionados 20 domicílios, por amostragem inversa. Em cada domicílio, um morador adulto foi selecionado com eqüiprobabilidade. O questionário modular, originalmente desenvolvido pela OMS, foi adaptado para se adequar às características do nosso meio.

    Carlos Eduardo Justen

    Full Text Available Este artigo, ao situar culturalmente os fenômenos da gestão e do desenvolvimento, em sua concepção tradicional, no projeto da modernidade e ao identificar o predomínio da unilateralidade reificada na interface entre gestão e desenvolvimento - a primeira vista como instrumento técnico submisso à via clássica do segundo - almeja evidenciar as potencialidades da compreensão e da construção de alternativas, tanto para a gestão como para o desenvolvimento, a partir da ressignificação dessa interface. Para tanto, o esforço foi direcionado ao resgate do que é comum aos fenômenos da gestão e do desenvolvimento - os substratos antropológico e ecológico -, nucleados nos princípios da reciprocidade dialógica, concretizadora da condição antropológica, e da finitude, caracterizadora da condição ecológica. Ao final, são apresentadas oito potenciais contribuições advindas da exploração renovada da interface entre a gestão e o desenvolvimento. Propôs-se, ainda, a substituição da lógica instrumental da eficiência financeira, comum à concepção tradicional dos fenômenos estudados, pela lógica da simbiose dialógica homem/natureza, uma vez que, como fenômenos sociais, desenvolvimento e gestão, mediados pelo meio, também são ecológicos em sua essência.

    Full Text Available Este trabalho objetiva abordar, no entrelaçamento entre linguística e filosofia, a ciência filosofia da linguagem no que se refere às duas orientações do pensamento filosófico-linguístico que buscam a resolução do problema de isolamento e delimitação da linguagem como objeto de estudo, a saber: o subjetivismo idealista e o objetivismo abstrato. São apontadas as principais proposições destas linhas mestras, seguidas de uma breve reflexão bakhtiniana sobre elas. Tal estudo é norteado pelo capítulo quarto, ‘Das Orientações do Pensamento Filosófico-linguístico’, da obra Marxismo e Filosofia da Linguagem de Mikhail Bakhtin. Algumas exemplificações são feitas, visando justificar as reflexões propostas.This work aims to approach, in the intertwining between linguistic and philosophy, the science phylosophy of the language with regard to two guidelines of the linguistic-philosophic thought which aim the resolution of the problem of the isolation and delimitation of the language as study object, to know, the idealist subjetivism and the abstract objetivism. The main proposals of these master lines followed by a brief bakhtinian reflection about them are pointed. Such study is guided by the chapter four, ‘Guidelines of the linguistic-Philosofic Thought’, of the classic Marxism and Language Philosophy by Mikhail Bakhtin. Some exemplifications are made in order to justify these reflections.

    Full Text Available The classical (boolean notion of refinement for behavioral interfaces of system components is the alternating refinement preorder. In this paper, we define a distance for interfaces, called interface simulation distance. It makes the alternating refinement preorder quantitative by, intuitively, tolerating errors (while counting them in the alternating simulation game. We show that the interface simulation distance satisfies the triangle inequality, that the distance between two interfaces does not increase under parallel composition with a third interface, and that the distance between two interfaces can be bounded from above and below by distances between abstractions of the two interfaces. We illustrate the framework, and the properties of the distances under composition of interfaces, with two case studies.

    2015-01-01

    In this paper we consider entanglement entropies in two-dimensional conformal field theories in the presence of topological interfaces. Tracing over one side of the interface, the leading term of the entropy remains unchanged. The interface however adds a subleading contribution, which can be interpreted as a relative (Kullback-Leibler) entropy with respect to the situation with no defect inserted. Reinterpreting boundaries as topological interfaces of a chiral half of the full theory, we rederive the left/right entanglement entropy in analogy with the interface case. We discuss WZW models and toroidal bosonic theories as examples.

    At the interface of two two-dimensional quantum systems, there may exist interface currents similar to edge currents in quantum Hall systems. It is proved that these interface currents are macroscopically quantized by an integer that is given by the difference of the Chern numbers of the two systems. It is also argued that at the interface between two time-reversal invariant systems with half-integer spin, one of which is trivial and the other non-trivial, there are dissipationless spin-polarized interface currents.

    Interfacing to the Web or programming interfaces for the Web is used to provide dynamic information for Web users. Using the Web as a transport system of information poses three constraints: namespace, statelessness and performance. To build interfaces on either server or client side of the Web one has to meet these constraints. Several examples, currently in use in High Energy Physics Experiments are described. They range from an interface to show where buildings are located to an interface showing active values of the On-line System of the DELPHI (CERN)..

    Full Text Available Nos últimos anos, a educação da pessoa privada de liberdade foi colocada na pauta político-educativa brasileira como um direito subjetivo. Apostou-se nela como ferramenta indispensável para a chamada reintegração social da pessoa encarcerada, porquanto pode contribuir para diminuir os índices alarmantes de reincidência. Neste artigo, refletimos sobre a problemática da reintegração com base nas histórias de vida narradas por mulheres presas em um presídio de João Pessoa – PB. Sem negar a importância da proposta pedagógica que a escola do presídio oferece, consideramos necessário estabelecer um diálogo entre as aprendizagens de vida e a experiência escolar da mulher antes de ser presa; as aprendizagens da prisão e suas expectativas e/ou planos para a vida em liberdade ao concluir a sentença e buscar se inserir numa sociedade regida por preconceitos sociais ainda enraizados. Questionamos se a escola prepara as mulheres para um mundo real ou para um mundo ilusório. De acordo com os depoimentos das mulheres, verificamos as inúmeras dificuldades que a escola da prisão enfrenta, para garantir às encarceradas o ideal ressocializador necessário ao enfrentamento do mundo real dentro e fora das grades. Também concluímos que, na prisão, é preciso investir em projetos e programas que estabeleçam mais articulação entre educação e trabalho e que contribuam para que a sociedade participe mais das proposições e ações voltadas aos ideais de reintegração social dessa população. Consideramos esse apartheid social também uma questão educacional que precisa ser aprofundada em âmbito acadêmico e enfrentada politicamente.In recent years, the education of people deprived of their freedom was placed on the political-educational agenda in Brazil as a subjective right. Great faith was placed in it as an indispensable tool for the so-called social reintegration of the imprisoned person, with its potential of contributing to

    Full Text Available Configura-se esta pesquisa em um estudo de cunho qualitativo e caráter bibliográfico, a qual almeja examinar a interrelação entre a gestão dos processos de adaptação social e o princípio da responsabilidade. Entende-se que se adentra em temática ampla e complexa, que perpassa todas as esferas do espaço público, visto que o fomento ao meio ambiente ecologicamente equilibrado afeta a todos os indivíduos, global e indistintamente. Nesse plano, mesmo sendo esta uma problemática mundial e que, consequentemente, requer uma solução abrangente, mostra-se indispensável que sejam buscadas alternativas já em âmbito local, pois é assim que se vai galgando o esclarecimento e a conscientização de todos os sujeitos. Para que o objetivo primordial desta investigação fosse alcançado utilizaram-se as concepções, de modo precípuo, de Anthony Giddens, quando este trata, especificamente, do manejo das complexidades sociais e econômicas introduzidas pelas novas formas de tecnologia, bem como a interconexão dos riscos a serem assumidos com o princípio de responsabilidade proposto por Hans Jonas. Dada a complexidade destas temáticas, o que se percebe é uma apatia social, em que a indiferença se faz, paulatinamente, mais presente. No entanto, é essencial compreender que, para haver a desobstaculização das problemáticas ainda arraigadas, a fim de almejar uma sociedade mais igual e mais responsável pelo meio ambiente, mostra-se crucial uma reformulação na práxis política, social e cultural. É mediante o engajamento político e o ativismo dos grupos sociais que se pode propor mudanças estruturais.

Valendo-se de autores críticos ao sistema capitalista, visa discutir o estágio como mecanismo de transição da educação para o trabalho; também objetiva apreender os conceitos, o condicionamento jurídico e as opiniões dos atores envolvidos com o estágio. Além de uma discussão teórica, são utilizados dados de pesquisas exploratórias recentes, realizadas com estudantes e trabalhadores da cidade de Guarapuava - PR, concluindo que o estágio apresenta-se como um canal importante de inserção profissional que contribui para a formação profissional, mas que também se presta para flexibilizar as relações de emprego e precarizar as condições de inserção e permanência no mercado de trabalho.Abstract: The present study reveals the results of a theoretical and field research about training as a means of insertion in the market. Based on the work of authors that criticize the capitalist system, our article aims at discussing the training as a mechanism of transition from education to labor; it also seeks to understand the concepts, the judicial conditioning, and the opinions of the trainees. Recent research data was used along with a theoretical discussion of the issue. The data were collected with students-workers from the city of Guarapuava, state of Paraná. Our conclusion was that training is an important means of professional initiation that consequently assists professional formation. However, it also loosens the work relations and reduces the opportunities for insertion and permanence in the market.

A primeira consiste na impregnação do reforço via polímero fundido; enquanto que a segunda faz uso de suspensões poliméricas aquosas, onde a impregnação do reforço ocorre pelo contato deste com a suspensão aquosa de partículas da matriz polimérica. Esta técnica combina a matriz polimérica em pó com um outro polímero formador da suspensão, um poli(ácido âmico - PAA, sendo que os dois polímeros são simultaneamente depositados sobre o reforço, durante a impregnação. Este mesmo PAA, em uma segunda fase do processo, é convertido termicamente em uma poliimida (PI podendo formar uma região de interfase entre o reforço e a matriz polimérica.

    The aim of this study was to investigate the effects of low-intensity irradiation with GaAlAs laser (red emission) on the ultrastructure of dentine-pulp interface after conventionally prepared class I cavity preparation. Two patients with 8 premolars for extraction indicated for orthodontic reasons. Class I cavities were prepared in these teeth that were then divided into two groups. The first group received a treatment with laser with continuous emission, {lambda}=660 nm, with maximum power output of 30 mW. The dosimetry applied was of approximately 2J/cm{sup 2}, directly and perpendicularly into the cavity in only one section. After the irradiation, the cavities were filled with composite resin. The second group received the same treatment, except by the laser therapy. Twenty-eight days after the preparation, the teeth were extracted and were processed for transmission electron microscopy analysis. Two sound teeth, without any preparation, were also studied. The irradiated group presented odontoblastic processes in higher contact with the extracellular matrix and the collagen fibers appeared more aggregated and organized than those of control group. These results were also observed in the healthy-teeth. Thus, we suggest that laser irradiation accelerates the recovery of the dental structures involved in the cavity preparation at the pre-dentine level. (author)

    Maria Cristina Franco Ferraz

    2014-06-01

    Full Text Available A exploração do estatuto paradoxal da pele - interface dentro/fora - permite ultrapassar a dicotomia metafísica superfície/profundidade, problematizando a tendência atual, também expressa na teoria, a um elogio das superfícies e a um horror por oposições dicotômicas. Possibilta avaliar as implicações do fechamento da porosidade da pele em formas de sociabilidade estimuladas na cultura da imagem, da exibição, do espetáculo, bem expressas pelo material inorgânico teflon. Sendo Poros, na visão grega, pai de Eros, a investigação acerca do estatuto paradoxal da pele convida a uma retomada do tema do erotismo. Partindo de perspectivas oferecidas por Agamben acerca da pornografia, ligada ao valor de exibição nas sociedades de espetáculo e de consumo, e relacionando-as a diversas reflexões de José Gil acerca do corpo e da pele, discute-se e convoca-se a abertura da porosidade da pele.

    In this paper we consider entanglement entropies in two-dimensional conformal field theories in the presence of topological interfaces. Tracing over one side of the interface, the leading term of the entropy remains unchanged. The interface however adds a subleading contribution, which can be interpreted as a relative (Kullback-Leibler) entropy with respect to the situation with no defect inserted. Reinterpreting boundaries as topological interfaces of a chiral half of the full theory, we rederive the left/right entanglement entropy in analogy with the interface case. We discuss WZW models and toroidal bosonic theories as examples. (copyright 2016 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    Interfaces are back, or perhaps they never left. The familiar Socratic conceit from the Phaedrus, of communication as the process of writing directly on the soul of the other, has returned to center stage in today's discussions of culture and media. Indeed Western thought has long construed media as a grand choice between two kinds of interfaces. Following the optimistic path, media seamlessly interface self and other in a transparent and immediate connection. But, following the pessimistic path, media are the obstacles to direct communion, disintegrating self and other into misunderstanding

    2005-01-21

    The incorporation of nanometric size particles in a matrix to form dielectric composites shows promise of materials (nanodielectrics) with new and improved properties. It is argued that the properties of the interfaces between the particles and the matrix, which will themselves be of nanometric dimensions, will have an increasingly dominant role in determining dielectric performance as the particle size decreases. The forces that determine the electrical and dielectric properties of interfaces are considered, with emphasis on the way in which they might influence composite behaviour. A number of examples are given in which interfaces at the nanometric level exercise both passive and active control over dielectric, optical and conductive properties. Electromechanical properties are also considered, and it is shown that interfaces have important electrostrictive and piezoelectric characteristics. It is demonstrated that the process of poling, namely subjecting macroscopic composite materials to electrical stress and raised temperatures to create piezoelectric materials, can be explained in terms of optimizing the collective response of the nanometric interfaces involved. If the electrical and electromechanical features are coupled to the long-established electrochemical properties, interfaces represent highly versatile active elements with considerable potential in nanotechnology.

  19. Lectures on random interfaces

    CERN Document Server

    Funaki, Tadahisa

    2016-01-01

    Interfaces are created to separate two distinct phases in a situation in which phase coexistence occurs. This book discusses randomly fluctuating interfaces in several different settings and from several points of view: discrete/continuum, microscopic/macroscopic, and static/dynamic theories. The following four topics in particular are dealt with in the book. Assuming that the interface is represented as a height function measured from a fixed-reference discretized hyperplane, the system is governed by the Hamiltonian of gradient of the height functions. This is a kind of effective interface model called ∇φ-interface model. The scaling limits are studied for Gaussian (or non-Gaussian) random fields with a pinning effect under a situation in which the rate functional of the corresponding large deviation principle has non-unique minimizers. Young diagrams determine decreasing interfaces, and their dynamics are introduced. The large-scale behavior of such dynamics is studied from the points of view of the hyd...

    Highlight: • This review article covers the topic of high temperature interface superconductivity. • New materials and techniques used for achieving interface superconductivity are discussed. • We emphasize the role played by the differences in structure and electronic properties at the interface with respect to the bulk of the constituents. - Abstract: High-T{sub c} superconductivity at interfaces has a history of more than a couple of decades. In this review we focus our attention on copper-oxide based heterostructures and multi-layers. We first discuss the technique, atomic layer-by-layer molecular beam epitaxy (ALL-MBE) engineering, that enabled High-T{sub c} Interface Superconductivity (HT-IS), and the challenges associated with the realization of high quality interfaces. Then we turn our attention to the experiments which shed light on the structure and properties of interfacial layers, allowing comparison to those of single-phase films and bulk crystals. Both ‘passive’ hetero-structures as well as surface-induced effects by external gating are discussed. We conclude by comparing HT-IS in cuprates and in other classes of materials, especially Fe-based superconductors, and by examining the grand challenges currently laying ahead for the field.

    This book contains the proceedings of the first Workshop on Interface Phenomena, organized jointly by the surface science groups at Dalhousie University and the University of Maine. It was our intention to concentrate on just three topics related to the kinetics of interface reactions which, in our opinion, were frequently obscured unnecessarily in the literature and whose fundamental nature warranted an extensive discussion to help clarify the issues, very much in the spirit of the Discussions of the Faraday Society. Each session (day) saw two principal speakers expounding the different views; the session chairmen were asked to summarize the ensuing discussions. To understand the complexity of interface reactions, paradigms must be formulated to provide a framework for the interpretation of experimen­ tal data and for the construction of theoretical models. Phenomenological approaches have been based on a small number of rate equations for the concentrations or mole numbers of the various species involved i...

    The Abstract Data Interface (ADI) is a system within which both abstract data models and their mappings on to file formats can be defined. The data model system is object-oriented and closely follows the Common Lisp Object System (CLOS) object model. Programming interfaces in both C and \\fortran are supplied, and are designed to be simple enough for use by users with limited software skills. The prototype system supports access to those FITS formats most commonly used in the X-ray community, as well as the Starlink NDF data format. New interfaces can be rapidly added to the system---these may communicate directly with the file system, other ADI objects or elsewhere (e.g., a network connection).

    2004-01-01

    The purpose of this study was to investigate the dentin/adhesive interfacial characteristics of three current commercial adhesives with different relative hydrophilic/hydrophobic composition, using a nondestructive staining technique. Dentin surfaces of 18 unerupted human third molars were randomly selected for treatment with one of three commercial dentin bonding agents according to manufacturers' instructions for the "wet" bonding technique. The adhesives were ranked based on hydrophilic/hydrophobic component ratios (ie, ability to dissolve in water), highest to lowest, as follows: Uno (Pulpdent) > Prime&Bond NT (PBNT, Dentsply Caulk) > Single Bond (SB, 3M ESPE). Dentin/adhesive (d/a) interface sections were stained with Goldner's trichrome, a classical bone stain, and examined using light microscopy. The extent and degree to which the adhesive encapsulates the demineralized dentin matrix is reflected in the color differences in the stained sections. The depth of demineralization appeared comparable among these bonding systems, but adhesive infiltration varied from highest to lowest as follows: Uno > PBNT > SB. The differential staining technique provided a clear representation of the depth of dentin demineralization and extent/degree of adhesive encapsulation of the exposed collagen at the d/a interface. This technique provides a mechanism for readily identifying vulnerable sites at the d/a interface. The composition of the one-bottle adhesive systems has a substantial effect on the interfacial structure of the d/a bond.

    Urban water systems consist of large-scale technical systems and both natural and man-made water bodies. The technical systems are essential components of urban infrastructure for water collection, treatment, storage and distribution, as well as for wastewater and runoff collection and subsequent treatment. Urban aquatic ecosystems are typically subject to strong human influences, which impair the quality of surface and ground waters, often with far-reaching impacts on downstream aquatic ecosystems and water users. The various surface and subsurface water bodies in urban environments can be viewed as interconnected compartments that are also extensively intertwined with a range of technical compartments of the urban water system. As a result, urban water systems are characterized by fluxes of water, solutes, gases and energy between contrasting compartments of a technical, natural or hybrid nature. Referred to as urban water interfaces, boundaries between and within these compartments are often specific to urban water systems. Urban water interfaces are generally characterized by steep physical and biogeochemical gradients, which promote high reaction rates. We hypothesize that they act as key sites of processes and fluxes with notable effects on overall system behaviour. By their very nature, urban water interfaces are heterogeneous and dynamic. Therefore, they increase spatial heterogeneity in urban areas and are also expected to contribute notably to the temporal dynamics of urban water systems, which often involve non-linear interactions and feedback mechanisms. Processes at and fluxes across urban water interfaces are complex and less well understood than within well-defined, homogeneous compartments, requiring both empirical investigations and new modelling approaches at both the process and system level. We advocate an integrative conceptual framework of the urban water system that considers interfaces as a key component to improve our fundamental

    An analog optical encryption system based on phase scrambling of two-dimensional optical images and holographic transformation for achieving large encryption keys and high encryption speed. An enciphering interface uses a spatial light modulator for converting a digital data stream into a two dimensional optical image. The optical image is further transformed into a hologram with a random phase distribution. The hologram is converted into digital form for transmission over a shared information channel. A respective deciphering interface at a receiver reverses the encrypting process by using a phase conjugate reconstruction of the phase scrambled hologram.

A "falsa interface" não é uma interface tecnológica que permite ao público a interação com um sistema digital, mas é um recurso poético, geralmente um aparato ou objeto artesanal com o qual o público interage com a obra de arte, que é um sistema. A "falsa interface" apresenta uma relação física, uma conexão com uma interface tecnológica. O público se relaciona ludicamente com a falsa interface e a interface tecnológica passa despercebida, em segundo plano, embora seja ela que capte e envie para o sistema a atuação do público.

  17. General purpose operator interface

    Bennion, S. I.

    1979-07-01

    The Hanford Engineering Development Laboratory in Richland, Washington is developing a general-purpose operator interface for controlling set-point driven processes. The interface concept is being developed around graphics display devices with touch-sensitive screens for direct interaction with the displays. Additional devices such as trackballs and keyboards are incorporated for the operator's convenience, but are not necessary for operation. The hardware and software are modular; only those capabilities needed for a particular application need to be used. The software is written in FORTRAN IV with minimal use of operating system calls to increase portability. Several ASCII files generated by the user define displays and correlate the display variables with the process parameters. It is also necessary for the user to build an interface routine which translates the internal graphics commands into device-specific commands. The interface is suited for both continuous flow processes and unit operations. An especially useful feature for controlling unit operations is the ability to generate and execute complex command sequences from ASCII files. This feature relieves operators of many repetitive tasks. 2 figures.

    Easy-to-use interfaces are a class of interfaces that fall between public access interfaces and graphical user interfaces in usability and cognitive difficulty. We describe characteristics of easy-to-use interfaces by the properties of four dimensions: selection, navigation, direct manipulation, and contextual metaphors. Another constraint we introduced was to include as little text as possible, and what text we have will be in at least four languages. Formative evaluations were conducted to identify and isolate these characteristics. Our application is a visual interface for a home automation system intended for a diverse set of users. The design will be expanded to accommodate the visually disabled in the near future.

Para testar um modelo de extração radicular macroscópico baseado no processo em escala microscópica, descreveram-se os resultados de um experimento com plantas cujo sistema radicular foi dividido entre camadas de solo com propriedades hidráulicas contrastantes. Um experimento de lisímetro dividido com plantas de sorgo foi realizado em Piracicaba-SP. Quatro lisímetros com dois compartimentos separados fisicamente (split-pot foram construídos e preenchidos com material de dois tipos de solo de diferentes classes texturais (um solo de textura média - AR e outro de textura argilosa - AG. Durante um mês e meio foi imposto um regime hídrico, alternando a irrigação entre os compartimentos. O teor de água nos compartimentos dos lisímetros foi monitorado com TDR e tensiômetros. O material dos dois solos foi analisado conforme método-padrão quanto às suas propriedades de retenção e condução da água. A densidade radicular foi determinada por pesagem no fim do experimento, tendo ficado em torno de duas vezes maior no solo AR do que no AG. Observou-se que a extração de água ocorreu preferencialmente do compartimento do lisímetro com maior potencial de fluxo matricial. Em certas ocasiões houve transferência de água do lado de maior para o de menor potencial de fluxo matricial, com a liberação da água ao solo pelo sistema radicular (hydraulic lift. Para compensar o efeito da heterogeneidade da distribuição radicular e da atividade radicular, incluiu-se, no modelo, um fator empírico f de correção.

    This special issue is devoted to illustrating important aspects and significant results in the field of modeling and simulation of water at interfaces with solutes or with confining substrates, focusing on a range of temperatures from ambient to supercooled. Understanding the behavior of water, in contact with different substrates and/or in solutions, is of pivotal importance for a wide range of applications in physics, chemistry and biochemistry. Simulations of confined and/or interfacial water are also relevant for testing how different its behavior is with respect to bulk water. Simulations and modeling in this field are of particular importance when studying supercooled regions where water shows anomalous properties. These considerations motivated the organization of a workshop at CECAM in the summer of 2009 which aimed to bring together scientists working with computer simulations on the properties of water in various environments with different methodologies. In this special issue, we collected a variety of interesting contributions from some of the speakers of the workshop. We have roughly classified the contributions into four groups. The papers of the first group address the properties of interfacial and confined water upon supercooling in an effort to understand the relation with anomalous behavior of supercooled bulk water. The second group deals with the specific problem of solvation. The next group deals with water in different environments by considering problems of great importance in technological and biological applications. Finally, the last group deals with quantum mechanical calculations related to the role of water in chemical processes. The first group of papers is introduced by the general paper of Stanley et al. The authors discuss recent progress in understanding the anomalies of water in bulk, nanoconfined, and biological environments. They present evidence that liquid water may display 'polymorphism', a property that can be present in

    Programmable logic controllers (PLCs) have very limited diagnostic and no prognostic capabilities, while current smart sensor designs do not have the capability to communicate over Fieldbus networks. The aim is to interface smart sensors with PLCs so that health and status information, such as failure mode identification and measurement tolerance, can be communicated via an industrial Fieldbus such as ControlNet. The SNE Industrial Fieldbus Interface (SIFI) is an embedded device that acts as a communication module in a networked smart sensor. The purpose is to enable a smart sensor to communicate health and status information to other devices, such as PLCs, via an industrial Fieldbus networking protocol. The SNE (Smart Network Element) is attached to a commercial off-the-shelf Any bus-S interface module through the SIFI. Numerous Anybus-S modules are available, each one designed to interface with a specific Fieldbus. Development of the SIFI focused on communications using the ControlNet protocol, but any of the Anybus-S modules can be used. The SIFI communicates with the Any-bus module via a data buffer and mailbox system on the Anybus module, and supplies power to the module. The Anybus module transmits and receives data on the Fieldbus using the proper protocol. The SIFI is intended to be connected to other existing SNE modules in order to monitor the health and status of a transducer. The SIFI can also monitor aspects of its own health using an onboard watchdog timer and voltage monitors. The SIFI also has the hardware to drive a touchscreen LCD (liquid crystal display) unit for manual configuration and status monitoring.

  14. Electrokinetics of heterogeneous interfaces.

    Zembala, Maria

    2004-12-31

    The influence of surface heterogeneity of various types on electrokinetic parameters is reviewed. The scope of the paper covers classical electrokinetic phenomena characterized by linear dependence of electrokinetic parameters vs. related driving forces. Neither non-linear effects nor the effects of non-equilibrium electric double layer are considered. A historical description of hydrodynamic aspect of electrokinetic phenomena exploiting the slip plane idea is briefly outlined. Attempts to estimate the slip plane location by comparing the diffuse layer and zeta potential values for some model systems are presented. The surface heterogeneity was divided into three categories. Heterogeneity of the first type was related to geometrical morphology of an interfacial region characterized by a considerable surface development producing a three-dimensional interfacial region. The effects of solid roughness, hairy surface, dense polymer layers and gel-like layers are discussed here. The very high surface conductivity detected for such interfaces seems to be a good indicator of the presence of structured layers of this type. Heterogeneous interfaces of the second class cover systems exhibiting non-uniform distribution of surface charge. The non-uniform surface charge distribution can be either of a molecular (discrete charges) or of a microscale (two-dimensional micropatches or three-dimensional structures formed by polyelectrolyte multilayers). The last class of systems examined includes interfaces composed of charged substrate covered by charged bulky objects (particles). In comparison to the homogeneous surfaces, adsorbed charged particles modify both hydrodynamic flow and the electrostatic field significantly altering the electrokinetic parameters. The new description of electrokinetics of composed interfaces presented here takes into account both hydrodynamic and electric field modification and is free of the previously assumed slip plane shift caused by adsorbed

    The DIA, in conjunction with the Army Research Lab (ARL), wants to create an Unmanned Ground Sensor (UGS) controller that is (a) interoperable across all controller platforms, (b) capable of easily adding new sensors, radios, and processes and (c) backward compatible with existing UGS systems. To achieve this, a Terra Harvest controller was created that used Java JRE 1.6 and an Open Services Gateway initiative (OSGi) platform, named Terra Harvest Open Software Environment (THOSE). OSGi is an extensible framework that provides a modularized environment for deploying functionality in "bundles". These bundles can publish, discover, and share services available from other external bundles or bundles provided by the controller core. With the addition of a web GUI used for interacting with THOSE, a natural step was then to create a common remote interface that allows 3rd party real-time interaction with the controller. This paper provides an overview of the THOSE system and its components as well as a description of the architectural structure of the remote interface, highlighting the interactions occurring between the controller and the remote interface and its role in providing a positive user experience for managing UGSS functions.

    Full Text Available Electronic apppliances are increasingly a part of our everyday lives. In particular, mobile devices, with their reduced dimensions with power rivaling desktop computers, have substantially augmented our communication abilities offering instant availability, anywhere, to everyone. These devices have become essential for human communication but also include a more comprehensive tool set to support productivity and leisure applications.However, the many applications commonly available are not adapted to people with special needs. Rather, most popular devices are targeted at teenagers or young adults with excellent eyesight and coordination. What is worse, most of the commonly used assistive control interfaces are not available in a mobile environment where user's position, accommodation and capacities can vary even widely.To try and address people with special needs new approaches and techniques are sorely needed. This paper presents a control interface to allow tetraplegic users to interact with electronic devices. Our method uses myographic information (Electromyography or EMG collected from residually controlled body areas. User evaluations validate electromyography as a daily wearable interface. In particular our results show that EMG can be used even in mobility contexts.

    Putnis, Andrew; Putnis, Christine V.

    2015-04-01

    While it is obvious that reactions between a mineral and an aqueous solution take place at the mineral-fluid interface it is only relatively recently that high spatial resolution studies have demonstrated how the local structure of the mineral surface and the chemical composition of the fluid at the interface control both the short-range and the long-range consequences of mineral-fluid interaction. Long-range consequences of fluid-mineral interaction control element cycles in the earth, the formation of ore-deposits, the chemical composition of the oceans through weathering of rocks and hence climate changes. Although weathering is clearly related to mineral dissolution, to what extent do experimentally measured dissolution rates of minerals help to understand weathering, especially weathering mechanisms? This question is related to the short-range, local reactions that take place when a mineral, that is not stable in the fluid, begins to dissolve. In this case the fluid composition at the interface will become supersaturated with respect to a different phase or phases. This may be a different composition of the same mineral e.g. a Ca-rich feldspar dissolving in a Na-rich solution results in a fluid at the interface which may be supersaturated with respect to an Na-rich feldspar. Alternatively, the interfacial fluid could be supersaturated with respect to a different mineral e.g. an Na-rich zeolite, depending on the temperature. Numerous experiments have shown that the precipitation of a more stable phase at the mineral-fluid interface results in a coupling between the dissolution and the precipitation, and the replacement of one mineral by another. This process separates the short-range mechanisms which depend only on the composition of the interfacial solution, and the long-range consequences that depend on the composition of the residual fluid released from the reacting parent mineral. Typically such residual fluids may carry metal ions tens to hundreds of

    2016-10-01

    A different type of Casimir-type interaction is theoretically predicted: a single-interface torque at a junction of an anisotropic material and a vacuum or another material system. The torque acts to reorient the polarizable microscopic units of the involved materials near the interface, and thus to change the internal structure of the materials. The single-interface torque depends on the zero-point energy of the interface localized and extended modes. Our theory demonstrates that the single-interface torque is essential to understand the Casimir physics of material systems with anisotropic elements and may influence the orientation of the director of nematic liquid crystals.

  2. Conceptual Framework for Aquatic Interfaces

    Science.gov (United States)

    Lewandowski, J.; Krause, S.

    2015-12-01

    Aquatic interfaces are generally characterized by steep gradients of physical, chemical and biological properties due to the contrast between the two adjacent environments. Innovative measurement techniques are required to study the spatially heterogeneous and temporally variable processes. Especially the different spatial and temporal scales are a large challenge. Due to the steep biogeochemical gradients and the intensive structural and compositional heterogeneity, enhanced biogeochemical processing rates are inherent to aquatic interfaces. Nevertheless, the effective turnover depends strongly on the residence time distribution along the flow paths and in sections with particular biogeochemical milieus and reaction kinetics. Thus, identification and characterization of the highly complex flow patterns in and across aquatic interfaces are crucial to understand biogeochemical processing along exchange flow paths and to quantify transport across aquatic interfaces. Hydrodynamic and biogeochemical processes are closely coupled at aquatic interfaces. However, interface processing rates are not only enhanced compared to the adjacent compartments that they connect; also completely different reactions might occur if certain thresholds are exceeded or the biogeochemical milieu differs significantly from the adjacent environments. Single events, temporal variability and spatial heterogeneity might increase overall processing rates of aquatic interfaces and thus, should not be neglected when studying aquatic interfaces. Aquatic interfaces are key zones relevant for the ecological state of the entire ecosystem and thus, understanding interface functioning and controls is paramount for ecosystem management. The overall aim of this contribution is a general conceptual framework for aquatic interfaces that is applicable to a wide range of systems, scales and processes.

  3. Transport processes at fluidic interfaces

    CERN Document Server

    Reusken, Arnold

    2017-01-01

    There are several physico-chemical processes that determine the behavior of multiphase fluid systems – e.g., the fluid dynamics in the different phases and the dynamics of the interface(s), mass transport between the fluids, adsorption effects at the interface, and transport of surfactants on the interface – and result in heterogeneous interface properties. In general, these processes are strongly coupled and local properties of the interface play a crucial role. A thorough understanding of the behavior of such complex flow problems must be based on physically sound mathematical models, which especially account for the local processes at the interface. This book presents recent findings on the rigorous derivation and mathematical analysis of such models and on the development of numerical methods for direct numerical simulations. Validation results are based on specifically designed experiments using high-resolution experimental techniques. A special feature of this book is its focus on an interdisciplina...

  4. Matched Interface and Boundary Method for Elasticity Interface Problems

    Science.gov (United States)

    Wang, Bao; Xia, Kelin; Wei, Guo-Wei

    2015-01-01

    Elasticity theory is an important component of continuum mechanics and has had widely spread applications in science and engineering. Material interfaces are ubiquity in nature and man-made devices, and often give rise to discontinuous coefficients in the governing elasticity equations. In this work, the matched interface and boundary (MIB) method is developed to address elasticity interface problems. Linear elasticity theory for both isotropic homogeneous and inhomogeneous media is employed. In our approach, Lamé’s parameters can have jumps across the interface and are allowed to be position dependent in modeling isotropic inhomogeneous material. Both strong discontinuity, i.e., discontinuous solution, and weak discontinuity, namely, discontinuous derivatives of the solution, are considered in the present study. In the proposed method, fictitious values are utilized so that the standard central finite different schemes can be employed regardless of the interface. Interface jump conditions are enforced on the interface, which in turn, accurately determines fictitious values. We design new MIB schemes to account for complex interface geometries. In particular, the cross derivatives in the elasticity equations are difficult to handle for complex interface geometries. We propose secondary fictitious values and construct geometry based interpolation schemes to overcome this difficulty. Numerous analytical examples are used to validate the accuracy, convergence and robustness of the present MIB method for elasticity interface problems with both small and large curvatures, strong and weak discontinuities, and constant and variable coefficients. Numerical tests indicate second order accuracy in both L∞ and L2 norms. PMID:25914439

    Full Text Available Agents trained by learning techniques provide a powerful approximation of state spaces in games that aretoo large for naive approaches. In the study Genetic Algorithms and Manual Interface was implementedand used to train agents for the board game LUDO. The state space of LUDO is generalized to a small setand encoded to suit the different techniques. The impact of variables and tactics applied in training aredetermined. Agents based on the techniques performed satisfactory against a baseline finite agent, and aGenetic Algorithm based agent performed satisfactory against competitors from the course. Better statespace representations will improve the success of learning based agents.

    Interfacial zones between tissues provide specialized, transitional junctions central to normal tissue function. Regenerative medicine strategies focused on multiple cell types and/or bi/tri-layered scaffolds do not provide continuously graded interfaces, severely limiting the integration and biological performance of engineered tissue substitutes. Inspired by the bone-soft tissue interface, we describe a biomaterial-mediated gene transfer strategy for spatially regulated genetic modification and differentiation of primary dermal fibroblasts within tissue-engineered constructs. We demonstrate that zonal organization of osteoblastic and fibroblastic cellular phenotypes can be engineered by a simple, one-step seeding of fibroblasts onto scaffolds containing a spatial distribution of retrovirus encoding the osteogenic transcription factor Runx2/Cbfa1. Gradients of immobilized retrovirus, achieved via deposition of controlled poly(L-lysine) densities, resulted in spatial patterns of transcription factor expression, osteoblastic differentiation, and mineralized matrix deposition. Notably, this graded distribution of mineral deposition and mechanical properties was maintained when implanted in vivo in an ectopic site. Development of this facile and robust strategy is significant toward the regeneration of continuous interfacial zones that mimic the cellular and microstructural characteristics of native tissue.

    2006-01-01

    Mercury Shopping Cart Interface (MSCI) is a reusable component of the Power User Interface 5.0 (PUI) program described in another article. MSCI is a means of encapsulating the logic and information needed to describe an orderable item consistent with Mercury Shopping Cart service protocol. Designed to be used with Web-browser software, MSCI generates Hypertext Markup Language (HTML) pages on which ordering information can be entered. MSCI comprises two types of Practical Extraction and Report Language (PERL) modules: template modules and shopping-cart logic modules. Template modules generate HTML pages for entering the required ordering details and enable submission of the order via a Hypertext Transfer Protocol (HTTP) post. Shopping cart modules encapsulate the logic and data needed to describe an individual orderable item to the Mercury Shopping Cart service. These modules evaluate information entered by the user to determine whether it is sufficient for the Shopping Cart service to process the order. Once an order has been passed from MSCI to a deployed Mercury Shopping Cart server, there is no further interaction with the user.

    A method and apparatus for providing high bandwidth and low noise mechanical input and output for computer systems. A gimbal mechanism provides two revolute degrees of freedom to an object about two axes of rotation. A linear axis member is coupled to the gimbal mechanism at the intersection of the two axes of rotation. The linear axis member is capable of being translated along a third axis to provide a third degree of freedom. The user object is coupled to the linear axis member and is thus translatable along the third axis so that the object can be moved along all three degrees of freedom. Transducers associated with the provided degrees of freedom include sensors and actuators and provide an electromechanical interface between the object and a digital processing system. Capstan drive mechanisms transmit forces between the transducers and the object. The linear axis member can also be rotated about its lengthwise axis to provide a fourth degree of freedom, and, optionally, a floating gimbal mechanism is coupled to the linear axis member to provide fifth and sixth degrees of freedom to an object. Transducer sensors are associated with the fourth, fifth, and sixth degrees of freedom. The interface is well suited for simulations of medical procedures and simulations in which an object such as a stylus or a joystick is moved and manipulated by the user.

    FIT stands for Foundations of Interface Technologies. Component-based design is widely considered as a major approach to developing systems in a time and cost effective way. Central in this approach is the notion of an interface. Interfaces summarize the externally visible properties of a component and are seen as a key to achieving component interoperability and to predict global system behavior based on the component behavior. To capture the intricacy of complex software products, rich interfaces have been proposed. These interfaces do not only specify syntactic properties, such as the signatures of methods and operations, but also take into account behavioral and extra-functional properties, such as quality of service, security and dependability. Rich interfaces have been proposed for describing, e.g., the legal sequences of messages or method calls accepted by components, or the resource and timing constraints in embedded software. The development of a rigorous framework for the specification and analysis...

    This work presents DaTo, a semi-automatically generated world atlas of biological databases and tools. It extracts raw information from all PubMed articles which contain exact URLs in their abstract section, followed by a manual curation of the abstract and the URL accessibility. DaTo features a user-friendly query interface, providing extensible URL-related annotations, such as the status, the location and the country of the URL. A graphical interaction network browser has also been integrated into the DaTo web interface to facilitate exploration of the relationship between different tools and databases with respect to their ontology-based semantic similarity. Using DaTo, the geographical locations, the health statuses, as well as the journal associations were evaluated with respect to the historical development of bioinformatics tools and databases over the last 20 years. We hope it will inspire the biological community to gain a systematic insight into bioinformatics resources. DaTo is accessible via http://bis.zju.edu.cn/DaTo/.

    A condition associated with the plasma boundary or other charged interface is reviewed. It is pointed out that in comparing theories and simulations of such interfaces, in order to avoid conflicting results it should be ascertained that the systems under consideration are thermodynamically equivalent. For the plasma-wall interface in equilibrium, the rate of change of the surface-charge density with respect to the surface potential must be positive.

    Porphyrins and other tetrapyrrole macrocycles possess an impressive variety of functional properties that have been exploited in natural and artificial systems. Different metal centres incorporated within the tetradentate ligand are key for achieving and regulating vital processes, including reversible axial ligation of adducts, electron transfer, light-harvesting and catalytic transformations. Tailored substituents optimize their performance, dictating their arrangement in specific environments and mediating the assembly of molecular nanoarchitectures. Here we review the current understanding of these species at well-defined interfaces, disclosing exquisite insights into their structural and chemical properties, and also discussing methods by which to manipulate their intramolecular and organizational features. The distinct characteristics arising from the interfacial confinement offer intriguing prospects for molecular science and advanced materials. We assess the role of surface interactions with respect to electronic and physicochemical characteristics, and describe in situ metallation pathways, molecular magnetism, rotation and switching. The engineering of nanostructures, organized layers, interfacial hybrid and bio-inspired systems is also addressed.

    Molecular spintronics, a field that utilizes the spin state of organic molecules to develop magneto-electronic devices, has shown an enormous scientific activity for more than a decade. But, in the last couple of years, new insights in understanding the fundamental phenomena of molecular interaction on magnetic surfaces, forming a hybrid interface, are presenting a new pathway for developing the subfield of interface-assisted molecular spintronics. The recent exploration of such hybrid interfaces involving carbon based aromatic molecules shows a significant excitement and promise over the previously studied single molecular magnets. In the above new scenario, hybridization of the molecular orbitals with the spin-polarized bands of the surface creates new interface states with unique electronic and magnetic character. This study opens up a molecular-genome initiative in designing new handles to functionalize the spin dependent electronic properties of the hybrid interface to construct spin-functional tailor-made devices. Through this article, we review this subject by presenting a fundamental understanding of the interface spin-chemistry and spin-physics by taking support of advanced computational and spectroscopy tools to investigate molecular spin responses with demonstration of new interface phenomena. Spin-polarized scanning tunneling spectroscopy is favorably considered to be an important tool to investigate these hybrid interfaces with intra-molecular spatial resolution. Finally, by addressing some of the recent findings, we propose novel device schemes towards building interface tailored molecular spintronic devices for applications in sensor, memory, and quantum computing.

Trata-se de traçar linhas e acoplar fragmentos históricos e literários com a finalidade de subsidiar a discussão contemporânea em torno da alegria. O procedimento genealógico vale-se de trechos das obras de Calímaco e Luciano de Samósata, da elegia erótica romana e da alegria cristã. O passo seguinte consiste em rastrear o pensamento da alegria na obra de Gilles Deleuze, especialmente em três momentos: uma passagem de Diferença e Repetição, um trecho dos Diálogos extraído de Da Superioridade da Literatura Anglo-americana e a comunicação Pensamento Nômade no Colóquio de Cerisy. A alegria não se define como sentimento ou emoção; ao contrário, está ligada à premissa de afirmação da vida e ao caráter trágico da existência.

    The PanDA (Production and Distributed Analysis) Workload Management System is used for ATLAS distributed production and analysis worldwide. The needs of ATLAS global computing imposed challenging requirements on PanDA design in areas such as scalability, robustness, automation, diagnostics, and usability for both production shifters and analysis users. Important to meeting these and other requirements is a comprehensive monitoring system. Through a system-wide job database, the PanDA monitor provides a comprehensive and coherent view of the system and job execution, from high level summaries to detailed drill-down job diagnostics. It is (like the rest of PanDA) an Apache-based Python application backed by Oracle. The presentation layer is HTML code generated on the fly in the Python application which is also responsible for managing database queries. However, this approach is lacking in user interface flexibility, simplicity of communication with external systems, and ease of maintenance. We decided to migrat...

    Power User Interface 5.0 (PUI) is a system of middleware, written for expert users in the Earth-science community, PUI enables expedited ordering of data granules on the basis of specific granule-identifying information that the users already know or can assemble. PUI also enables expert users to perform quick searches for orderablegranule information for use in preparing orders. PUI 5.0 is available in two versions (note: PUI 6.0 has command-line mode only): a Web-based application program and a UNIX command-line- mode client program. Both versions include modules that perform data-granule-ordering functions in conjunction with external systems. The Web-based version works with Earth Observing System Clearing House (ECHO) metadata catalog and order-entry services and with an open-source order-service broker server component, called the Mercury Shopping Cart, that is provided separately by Oak Ridge National Laboratory through the Department of Energy. The command-line version works with the ECHO metadata and order-entry process service. Both versions of PUI ultimately use ECHO to process an order to be sent to a data provider. Ordered data are provided through means outside the PUI software system.

    Astronomers are constantly looking for easier ways to access multiple data sets. While much effort is spent on VO, little thought is given to the types of User Interfaces we need to effectively search this sort of data. For instance, an astronomer might need to search Spitzer, WISE, and 2MASS catalogs and images then see the results presented together in one UI. Moving seamlessly between data sets is key to presenting integrated results. Results need to be viewed using first class, web based, integrated FITS viewers, XY Plots, and advanced table display tools. These components should be able to handle very large datasets. To make a powerful Web based UI that can manage and present multiple searches to the user requires taking advantage of many HTML5 features. AJAX is used to start searches and present results. Push notifications (Server Sent Events) monitor background jobs. Canvas is required for advanced result displays. Lesser known CSS3 technologies makes it all flow seamlessly together. At IPAC, we have been developing our Firefly toolkit for several years. We are now using it to solve this multiple data set, multiple queries, and integrated presentation problem to create a powerful research experience. Firefly was created in IRSA, the NASA/IPAC Infrared Science Archive (http://irsa.ipac.caltech.edu). Firefly is the core for applications serving many project archives, including Spitzer, Planck, WISE, PTF, LSST and others. It is also used in IRSA's new Finder Chart and catalog and image displays.

    Originally organised as a sub-system in the DAQ/EF-1 Prototype Project, the Detector Interface Group (DIG) was an information exchange channel between the Detector systems and the Data Acquisition to provide critical detector information for prototype design and detector integration. After the reorganisation of the Trigger/DAQ Project and of Technical Coordination, the necessity to provide an adequate context for integration of detectors with the Trigger and DAQ lead to organisation of the DIG as one of the activities of Technical Coordination. Such an organisation emphasises the ATLAS wide coordination of the Trigger and DAQ exploitation aspects, which go beyond the domain of the Trigger/DAQ project itself. As part of Technical Coordination, the DIG provides the natural environment for the common work of Trigger/DAQ and detector experts.

  20. Interface roughening and pinning

    Science.gov (United States)

    Roux, Stéphane; Hansen, Alex

    1994-04-01

    We study a simple model for thé pinning of an interface by impurities with random strengths, and thé depinning due to thé applied pressure, in a quasi-static propagation lirait. The model is very close to thé so called "Robin Hood" model introduced by Zaitsev. It is designed to describe e.g. thé invasion of a wetting fluid (imbibition) in a heterogeneous porous medium containing a second immiscible fluid. The relation between this model and other previously proposed approaches is discussed. The front of thé invaded domain is shown to develop a self-affine structure with an increase of thé roughness as a power-law of thé injected volume. The value of thé apparent roughness exponent can be favorably compared to some experimental measurements although we argue that thé true roughness exponent is out of reach of commonly used methods. We show that thé distribution f(d, Δ t) of distances d between discrete local invasions at a time interval Δ t can be described by a scaling law f(d, Δ t) = d^{-1}\\varphi(d/sqrt{Δ t}). This form can be obtained from thé identification of a hierarchical structure of "bursts" in thé pressure signal. Those "bursts" are quahtatively similar to those observed in quasistatic drainage, (i.e. invasion percolation), although characterized by différent scaling indices. Nous étudions un modèle simple pour analyser l'accrochage d'une interface sur des impuretés et le décrochage sous l'effet d'une pression appliquée, dans une limite quasi-statique. Ce modèle est très voisin du modèle "Robin Hood" introduit par Zaitsev. Il s'applique en particulier à l'invasion d'un fluide mouillant (imbibition) dans un milieu poreux hétérogène contenant un fluide immiscible. Nous discutons les relations entre ce modèle et d'autres approches proposées pour décrire ce phénomène.

    A systematic study of the structure and dynamics of nanoparticles (NP) and NP-surfactants was performed. The ligands attached to both the NPs and NP-surfactants dictate the manner in which the nanoscopic materials assemble at fluid interfaces. Studies have shown that a single layer of the nanoscpic materials form at the interface to reduce the interactions between the two immiscible fluids. The shape of the NP is, also, important, where for spherical particles, a disordered, liquid-like monolayer forms, and, for nanorods, ordered domains at the interface is found and, if the monolayers are compressed, the orientation of the nanorods with respect to the interface can change. By associating end-functionalized polymers to the NPs assembled at the interface, NP-surfactants are formed that increase the energetic gain in segregating each NP at the interface which allows the NP-surfactants to jam at the interface when compressed. This has opened the possibility of structuring the two liquids by freezing in shape changes of the liquids.

  2. Playful user interfaces interfaces that invite social and physical interaction

    2014-01-01

    The book is about user interfaces to applications that have been designed for social and physical interaction. The interfaces are ‘playful’, that is, users feel challenged to engage in social and physical interaction because that will be fun. The topics that will be present in this book are interactive playgrounds, urban games using mobiles, sensor-equipped environments for playing, child-computer interaction, tangible game interfaces, interactive tabletop technology and applications, full-body interaction, exertion games, persuasion, engagement, evaluation, and user experience. Readers of the book will not only get a survey of state-of-the-art research in these areas, but the chapters in this book will also provide a vision of the future where playful interfaces will be ubiquitous, that is, present and integrated in home, office, recreational, sports and urban environments, emphasizing that in the future in these environments game elements will be integrated and welcomed.

    At interfaces between complex oxides, electronic systems with unusual electronic properties can be generated. We report on superconductivity in the electron gas formed at the interface between two insulating dielectric perovskite oxides, LaAlO3 and SrTiO3. The behavior of the electron gas is that of a two-dimensional superconductor, confined to a thin sheet at the interface. The superconducting transition temperature of congruent with 200 millikelvin provides a strict upper limit to the thickness of the superconducting layer of congruent with 10 nanometers.

    In summary, an interface gateway is able to quickly create and support relationships. In the healthcare environment of the 1990s, organization executives will be faced with an exponential increase in the number of provider, payor and employer alliances, affiliations and acquisitions. One of the recurring requirements in this scenario is the need to share information. Most of the data standards in existence today do not address the vast interface requirements of these organizations. However, the capabilities, flexibility and capacity of interface gateways can allow these relationships to be created and supported in a fraction of the time that conventional methods require.

Esse tema é objeto tanto da área de marketing estratégico quanto da de estratégia empresarial. Nas duas áreas, há um ponto de consenso que afirma que a empresa deve diferenciar sua oferta para conquistar e manter vantagem competitiva. Mas, os estudos conduzidos por meio do modelo de Campos e Armas da Competição revelaram que a empresa pode diferenciar seu produto e/ou serviço de modo mais amplo, levando em consideração, na formulação da sua estratégia competitiva, também o campo da competição, quer do produto, quer dela própria. Assim, o objetivo deste artigo é evidenciar que, para a empresa ser competitiva, além de diferenciar seu produto e/ou seu serviço no sentido tradicional, ela precisa: 1 diferenciar seu produto incluindo a definição em quais campos vai competir em cada segmento; e 2 escolher as armas da competição que irá utilizar e definir a intensidade de cada arma. Para atingir tal objetivo, foram necessários vários conceitos do modelo de Campos e Armas da Competição: campo da competição, arma da competição, tese do modelo, configuração dos campos da competição, campo coadjuvante, produto coadjuvante e par produto-mercado. Como uma proposta inovadora sempre desperta dúvida, é mostrado o processo de validação do modelo de Campos e Armas da Competição e são discutidas sua universalidade, consistência e completude.

  17. Dispersive transport across interfaces

    Berkowitz, Brian; Adler, Pierre

    2015-04-01

    Experiments demonstrating asymmetrical dispersive transport of a conservative tracer across interfaces between different porous materials have recently been performed. Here, this phenomenon is studied numerically on the pore scale. The flow field is derived by solving the Stokes equation. The dispersive transport is simulated by a large number of particles undergoing random walks under the simultaneous action of convection and diffusion. Two main two-dimensional configurations are studied; each consists of two segments (called coarse and fine) with the same structure, porosity, and length along the main flow, but different characteristic solid/pore sizes. One structure consists of two channels containing cavities of different sizes, and the second of square "grains" of different sizes. At time t=0, a large number of particles is injected (as a pulse) around a given cross-section. The corresponding breakthrough curves (BTCs) are registered as functions of time at six different cross sections. Calculations are made twice; in the first case (CtoF), particles are injected in the coarse side and are transported towards the fine one; in the second one (FtoC), the opposite case is studied. These calculations are performed for various Péclet numbers (Pe). Comparison of the resulting BTCs shows features that are similar to experimental observations, but with qualitative and quantitative differences. The influences of the medium, of the injection and observation planes, and of Pe are detailed and discussed. A BTC for pulse injection can be characterized by its maximum M(t_M) and the time tM at which it occurs. The observed differences for channels bounded by cavities are very small. However for the granular structures, M(t_M) is always larger for FtoC than for CtoF ; tM depends on all the parameters, namely Pe, the size ratio between the large and small grains, the injection and the observation planes. The numerical results are systematically compared with solutions of one

    We present here a survey of recent results concerning the mathematical analysis of instabilities of the interface between two incompressible, non viscous, fluids of constant density and vorticity concentrated on the interface. This configuration includes the so-called Kelvin-Helmholtz (the two densities are equal), Rayleigh-Taylor (two different, nonzero, densities) and the water waves (one of the densities is zero) problems. After a brief review of results concerning strong and weak solutions of the Euler equation, we derive interface equations (such as the Birkhoff-Rott equation) that describe the motion of the interface. A linear analysis allows us to exhibit the main features of these equations (such as ellipticity properties); the consequences for the full, non linear, equations are then described. In particular, the solutions of the Kelvin-Helmholtz and Rayleigh-Taylor problems are necessarily analytic if they are above a certain threshold of regularity (a consequence is the illposedness of the initial ...

    Full Text Available Recent technological advances in organic field-effect transistors (OFETs have triggered intensive research into the molecular and mesoscale structures of organic semiconductor films that determine their charge-transport characteristics. Since the molecular structure and morphology of an organic semiconductor are largely determined by the properties of the interface between the organic film and the insulator, a great deal of research has focused on interface engineering. We review recent progress in interface engineering for the fabrication of high-performance OFETs and, in particular, engineering of the interfaces between semiconductors and insulators. The effects of interfacial characteristics on the molecular and mesoscale structures of π-conjugated molecules and the performance of OFET devices are discussed.

    2016-10-11

    TensorFlow is a second-generation open-source machine learning software library with a built-in framework for implementing neural networks in wide variety of perceptual tasks. Although TensorFlow usage is well established with computer vision datasets, the TensorFlow interface with DICOM formats for medical imaging remains to be established. Our goal is to extend the TensorFlow API to accept raw DICOM images as input; 1513 DaTscan DICOM images were obtained from the Parkinson's Progression Markers Initiative (PPMI) database. DICOM pixel intensities were extracted and shaped into tensors, or n-dimensional arrays, to populate the training, validation, and test input datasets for machine learning. A simple neural network was constructed in TensorFlow to classify images into normal or Parkinson's disease groups. Training was executed over 1000 iterations for each cross-validation set. The gradient descent optimization and Adagrad optimization algorithms were used to minimize cross-entropy between the predicted and ground-truth labels. Cross-validation was performed ten times to produce a mean accuracy of 0.938 ± 0.047 (95 % CI 0.908-0.967). The mean sensitivity was 0.974 ± 0.043 (95 % CI 0.947-1.00) and mean specificity was 0.822 ± 0.207 (95 % CI 0.694-0.950). We extended the TensorFlow API to enable DICOM compatibility in the context of DaTscan image analysis. We implemented a neural network classifier that produces diagnostic accuracies on par with excellent results from previous machine learning models. These results indicate the potential role of TensorFlow as a useful adjunct diagnostic tool in the clinical setting.

  13. Active matter clusters at interfaces.

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Collective and directed motility or swarming is an emergent phenomenon displayed by many self-organized assemblies of active biological matter such as clusters of embryonic cells during tissue development, cancerous cells during tumor formation and metastasis, colonies of bacteria in a biofilm, or even flocks of birds and schools of fish at the macro-scale. Such clusters typically encounter very heterogeneous environments. What happens when a cluster encounters an interface between two different environments has implications for its function and fate. Here we study this problem by using a mathematical model of a cluster that treats it as a single cohesive unit that moves in two dimensions by exerting a force/torque per unit area whose magnitude depends on the nature of the local environment. We find that low speed (overdamped clusters encountering an interface with a moderate difference in properties can lead to refraction or even total internal reflection of the cluster. For large speeds (underdamped, where inertia dominates, the clusters show more complex behaviors crossing the interface multiple times and deviating from the predictable refraction and reflection for the low velocity clusters. We then present an extreme limit of the model in the absence of rotational damping where clusters can become stuck spiraling along the interface or move in large circular trajectories after leaving the interface. Our results show a wide range of behaviors that occur when collectively moving active biological matter moves across interfaces and these insights can be used to control motion by patterning environments.

Our results show a wide range of behaviors that occur when collectively moving active biological matter moves across interfaces and these insights can be used to control motion by patterning environments.

  15. Hydrophobic effect at aqueous interfaces

    2005-01-01

    Conceptual basis for hydrophobic effects in bulk water and at aqueous interfaces have similar conceptual basis but often manifests itself differently. Using a wide range of computer simulations as the basis, I will review different forms of hydrophobic effects at a variety of interfaces starting from simple liquid-vapor and water-oil interfaces and progressing to water-membrane interfaces. I will start with discussing how water is organized at different interfaces, stressing both similarities and differences. The main thread is that, as in the bulk liquid, hydrophobic effects have profound influence on conformational equilibria and organization of both small molecules and macromolecules, but the result of this influence is quite different. Specifically, it will be shown that many small, but not necessarily amphiphilic molecules tend to accumulate at the interface and, and this tendency will be explained. Furthermore, I will show that many short peptides that are disordered in water spontaneously fold into well-defined structures in the interfacial environment. Biological implications of this self-organizing effect will be discussed.

  16. Spoken Dialogue Interfaces: Integrating Usability

    Spiliotopoulos, Dimitris; Stavropoulou, Pepi; Kouroupetroglou, Georgios

    Usability is a fundamental requirement for natural language interfaces. Usability evaluation reflects the impact of the interface and the acceptance from the users. This work examines the potential of usability evaluation in terms of issues and methodologies for spoken dialogue interfaces along with the appropriate designer-needs analysis. It unfolds the perspective to the usability integration in the spoken language interface design lifecycle and provides a framework description for creating and testing usable content and applications for conversational interfaces. Main concerns include the problem identification of design issues for usability design and evaluation, the use of customer experience for the design of voice interfaces and dialogue, and the problems that arise from real-life deployment. Moreover it presents a real-life paradigm of a hands-on approach for applying usability methodologies in a spoken dialogue application environment to compare against a DTMF approach. Finally, the scope and interpretation of results from both the designer and the user standpoint of usability evaluation are discussed.

    Full Text Available This article presents the results of a two year research of a group associated to the Universitas/BR network with emphasis on the relationship between the evaluation process and the higher education growth. The analysis explains how the expansion movements and the evaluation results can explain the association between assessment, growth, quality and regulation of Higher Education in Brazil. The focus was mainly on the goal stated in government policies that evaluation should guide the expansion and on how the media reported the evaluation processes. The terms of the former presidents Fernando Henrique Cardoso (1995-2002 and Luiz Inácio Lula da Silva (2003-2010 were focused. The obvious expansion, led specially by for-profit institutions, occurred without a logical plan and with no interference of any evaluation mechanism, although it obeyed the norms dictated by the State. In FHC government we had a regulatory conception limited to the products (National Graduation Course Exam and in Lula’s government the focus was in promoting quality with global and qualitative analysis, led by the National Higher Education Evaluation System (SINAES, with the purpose to integrate the assessment of students, courses and institutions. The results show that in both periods there was regularity of the exams, but very little qualitative evaluations, besides the invisibility of this process in the media. Despite the differences between the propositions, the evaluation process took place based on regulation demands that were not linked with the expansion policy. Apresenta o resultado de dois anos de pesquisa de investigadores vinculados à Rede Universitas/BR com foco nas relações entre os processos de avaliação e expansão da educação superior (ES no período pós-LDB/1996.

  2. Magnetosheath-cusp interface

    2004-01-01

    Full Text Available We advance the achievements of Interball-1 and other contemporary missions in exploration of the magnetosheath-cusp interface. Extensive discussion of published results is accompanied by presentation of new data from a case study and a comparison of those data within the broader context of three-year magnetopause (MP crossings by Interball-1. Multi-spacecraft boundary layer studies reveal that in ∼80% of the cases the interaction of the magnetosheath (MSH flow with the high latitude MP produces a layer containing strong nonlinear turbulence, called the turbulent boundary layer (TBL. The TBL contains wave trains with flows at approximately the Alfvén speed along field lines and "diamagnetic bubbles" with small magnetic fields inside. A comparison of the multi-point measurements obtained on 29 May 1996 with a global MHD model indicates that three types of populating processes should be operative:

    • large-scale (∼few RE anti-parallel merging at sites remote from the cusp;
    • medium-scale (few thousandkm local TBL-merging of fields that are anti-parallel on average;
    • small-scale (few hundredkm bursty reconnection of fluctuating magnetic fields, representing a continuous mechanism for MSH plasma inflow into the magnetosphere, which could dominate in quasi-steady cases.

    The lowest frequency (∼1–2mHz TBL fluctuations are traced throughout the magnetosheath from the post-bow shock region up to the inner magnetopause border. The resonance of these fluctuations with dayside flux tubes might provide an effective correlative link for the entire dayside region of the solar wind interaction with the magnetopause and cusp ionosphere. The TBL disturbances are characterized by kinked, double-sloped wave power spectra and, most probably, three-wave cascading. Both elliptical polarization and nearly Alfvénic phase velocities with characteristic dispersion indicate the

  3. Interface groups and financial transfer architectures

    CERN Document Server

    Bergstra, Jan A

    2007-01-01

    Analytic execution architectures have been proposed by the same authors as a means to conceptualize the cooperation between heterogeneous collectives of components such as programs, threads, states and services. Interface groups have been proposed as a means to formalize interface information concerning analytic execution architectures. These concepts are adapted to organization architectures with a focus on financial transfers. Interface groups (and monoids) now provide a technique to combine interface elements into interfaces with the flexibility to distinguish between directions of flow dependent on entity naming. The main principle exploiting interface groups is that when composing a closed system of a collection of interacting components, the sum of their interfaces must vanish in the interface group modulo reflection. This certainly matters for financial transfer interfaces. As an example of this, we specify an interface group and within it some specific interfaces concerning the financial transfer arch...

  7. XML Translator for Interface Descriptions

    Science.gov (United States)

    Boroson, Elizabeth R.

    2009-01-01

    A computer program defines an XML schema for specifying the interface to a generic FPGA from the perspective of software that will interact with the device. This XML interface description is then translated into header files for C, Verilog, and VHDL. User interface definition input is checked via both the provided XML schema and the translator module to ensure consistency and accuracy. Currently, programming used on both sides of an interface is inconsistent. This makes it hard to find and fix errors. By using a common schema, both sides are forced to use the same structure by using the same framework and toolset. This makes for easy identification of problems, which leads to the ability to formulate a solution. The toolset contains constants that allow a programmer to use each register, and to access each field in the register. Once programming is complete, the translator is run as part of the make process, which ensures that whenever an interface is changed, all of the code that uses the header files describing it is recompiled.

    Traditionally the interaction between users and the Grid is done with command line tools. However, these tools are difficult to use by non-expert users providing minimal help and generating outputs not always easy to understand especially in case of errors. Graphical User Interfaces are typically limited to providing access to the monitoring or accounting information and concentrate on some particular aspects failing to cover the full spectrum of grid control tasks. To make the Grid more user friendly more complete graphical interfaces are needed. Within the DIRAC project we have attempted to construct a Web based User Interface that provides means not only for monitoring the system behavior but also allows to steer the main user activities on the grid. Using DIRAC's web interface a user can easily track jobs and data. It provides access to job information and allows performing actions on jobs such as killing or deleting. Data managers can define and monitor file transfer activity as well as check requests set by jobs. Production managers can define and follow large data productions and react if necessary by stopping or starting them. The Web Portal is build following all the grid security standards and using modern Web 2.0 technologies which allow to achieve the user experience similar to the desktop applications. Details of the DIRAC Web Portal architecture and User Interface will be presented and discussed.

    Full Text Available The composition and biomass of the microalgal community at the water-column/sediment interface on the continental shelf off Parana State (Brazil were studied every 2 months during 1999. Samples for cell identification and determination of chlorophyll a were taken from the interface layer and at discrete depths up to 4 m above the sediment. Results showed a community mainly formed by benthic and planktonic diatoms >30 µm, benthic diatoms 30 µm, which accounted for most of the pigment biomass, were resuspended from the interface after turbulent periods, and may take advantage of calm periods to stay and grow at the interface. Small benthic diatoms were more susceptible to wind-induced turbulence occurring in higher densities in the water column just above the water-sediment interface. A cyanobacterial bloom (Trichodesmiun was observed at these bottom layers in the spring-summer periods.A composição geral e a biomassa da comunidade microalgal da interface sedimento/água da plataforma do Estado do Paraná (Brasil foram estudadas em 1999 em relação ao regime de ventos.

    1997-01-01

    Tools which make use of computational processes - mathematical, algorithmic and/or knowledge-based - to perform portions of the design, evaluation and/or construction of interfaces have become increasingly available and powerful. Nevertheless, there is little agreement as to the appropriate role for a computational tool to play in the interface design process. Current tools fall into broad classes depending on which portions, and how much, of the design process they automate. The purpose of this panel is to review and generalize about computational approaches developed to date, discuss the tasks which for which they are suited, and suggest methods to enhance their utility and acceptance. Panel participants represent a wide diversity of application domains and methodologies. This should provide for lively discussion about implementation approaches, accuracy of design decisions, acceptability of representational tradeoffs and the optimal role for a computational tool to play in the interface design process.

    On behalf of the U.S. Department of Energy, PNNL has explored and expanded upon a simple control interface that might have merit for the inexpensive communication of smart grid operational objectives (demand response, for example) to small electric end-use devices and appliances. The approach relies on bi-directional communication via the electrical voltage states of from one to eight shared interconnection pins. The name PinBus has been suggested and adopted for the proposed interface protocol. The protocol is defined through the presentation of state diagrams and the pins’ functional definitions. Both simulations and laboratory demonstrations are being conducted to demonstrate the elegance and power of the suggested approach. PinBus supports a very high degree of interoperability across its interfaces, allowing innumerable pairings of devices and communication protocols and supporting the practice of practically any smart grid use case.

    Jackson, Andrew; Fetz, Eberhard E

    2011-10-01

    Neuroscience is just beginning to understand the neural computations that underlie our remarkable capacity to learn new motor tasks. Studies of natural movements have emphasized the importance of concepts such as dimensionality reduction within hierarchical levels of redundancy, optimization of behavior in the presence of sensorimotor noise and internal models for predictive control. These concepts also provide a framework for understanding the improvements in performance seen in myoelectric-controlled interface and brain-machine interface paradigms. Recent experiments reveal how volitional activity in the motor system combines with sensory feedback to shape neural representations and drives adaptation of behavior. By elucidating these mechanisms, a new generation of intelligent interfaces can be designed to exploit neural plasticity and restore function after neurological injury.

  1. A comparative study of interface reconstruction algorithms in molten metal flow

    Young-Sim Choi

    2013-01-01

    Full Text Available In the present research, two numerical schemes for improving the accuracy of the solution in the flow simulation of molten metal were applied. One method is the Piecewise Linear Interface Calculation (PLIC method and the other is the Donor-Acceptor (D-A method. To verify the module of the interface reconstruction algorithms, simple problems were tested. After these validations, the accuracy and efficiency of these two methods were compared by simulating various real products. On the numerical simulation of free surface flow, it is possible for the PLIC method to track very accurately the interface between phases. The PLIC method, however, has the weak point in that a lot of computational time is required, though it shows the more accurate interface reconstruction. The Donor-Acceptor method has enough effectiveness in the macro-observation of a mold filling sequence though it shows inferior accuracy. Therefore, for the problems that need the accurate solution, PLIC is more appropriate than D-A. More accuracy may cause less efficiency in numerical analysis. Which method between D-A method and PLIC method should be chosen depends on the product.

    2014-06-01

    Full Text Available O presente artigo apresenta uma reflexão sobre as interfaces entre teologia e espiritualidade. Sabe-se que a teologia escolástica se tornou muito especulativa e racional, relegando a espiritualidade à piedade popular e suas devoções. Teólogos modernos redescobrem a dimensão existencial da teologia, uma vez que, enquanto ciência da revelação, ela busca uma linguagem racional coerente para a experiência cristã de Deus. A teologia conjuga fé e razão; a experiência de fé, no entanto, é anterior à reflexão racional que, em última instância, está a serviço da experiência, para iluminá-la e torná-la mais fiel à experiência fundamental da revelação de Jesus Cristo, que se encontra nas Escrituras. Nesse sentido, a espiritualidade emerge como aspecto intrínseco à teologia. A teologia, se permanecer fiel à sua missão, se expressará existencialmente como sapientia fidei. Este artigo trata, portanto, da relação evidente, mas muitas vezes esquecida, entre teologia (discurso racional e espiritualidade (experiência cristã de Deus, mostrando que a teologia só cumpre o seu papel de serviço à Igreja se conduz o crente à experiência do mistério indizível de Deus que se aproximou de nós em Jesus Cristo.

    In the years since Jakob Nielsen's classic collection on interface consistency first appeared, much has changed, and much has stayed the same. On the one hand, there's been exponential growth in the opportunities for following or disregarding the principles of interface consistency-more computers, more applications, more users, and of course the vast expanse of the Web. On the other, there are the principles themselves, as persistent and as valuable as ever. In these contributed chapters, you'll find details on many methods for seeking and enforcing consistency, along with bottom-line analys

  5. Artful interfaces within biological materials

    Full Text Available Biological materials have a wide range of mechanical properties matching their biological function. This is achieved via complex structural hierarchies, spanning many length scales, arising from the assembly of different sized building blocks during growth. The interfaces between these building blocks can increase resistance to fracture, join materials of different character, make them deform more easily and provide motility. While they represent only a tiny fraction of the overall volume, interfaces are essential for the integrity and function of the overall tissue. Understanding their construction principles, often based on specialized molecular assemblies, may change our current thinking about composite materials.

    Cartesian grid methods encompass a wide variety of techniques used to solve partial differential equations in more than one space dimension on uniform Cartesian grids even when the underlying geometry is complex and not aligned with the grid. The authors` groups work on Immersed Interface Methods (IIM) was originally motivated by the desire to understand and improve the ``Immersed Boundary Method``, developed by Charles Peskin to solve incompressible Navier-Stokes equations in complicated geometries with moving elastic boundaries. This report briefly discusses the development of the Immersed Interface Methods and gives examples of application of the method in solving several partial differential equations.

    Digital holographic microscopy (DHM) is a powerful in-vitro biological imaging tool. In this paper, we report a fully automated off-axis digital holographic microscopy system completed with a graphical user interface in the Matlab environment. The interface primarily includes Fourier domain processing, phase reconstruction, aberration compensation and autofocusing. A variety of imaging operations such as region of interest selection, de-noising mode (filtering and averaging), low frame rate imaging for immediate reconstruction and high frame rate imaging routine ( 27 fps) are implemented to facilitate ease of use.

    Methods of improving the durability of thin-film laser mirror coatings for 10.6 microm using thorium fluoride, zinc selenide, and zinc sulfide materials have been investigated. The largest improvement in film durability was obtained by using inhomogeneous interface fabrication for all the dielectric-dielectric interfaces and by incorporating cerium fluoride protective overcoating material into the film design. Experimental results are given for enhanced reflectors, polarization-selective coatings, and buried-grating aperture-sharing coatings designed for high-power laser applications.

    Interfaces or phase boundaries are a unique chemical environment relative to individual gas, liquid, or solid phases. Interfacial reaction mechanisms and kinetics are often at variance with homogeneous chemistry due to mass transfer, molecular orientation, and catalytic effects. Aqueous interfaces are a common subject of environmental science and engineering research, and three environmentally relevant aqueous interfaces are investigated in this thesis: 1) fluorochemical sonochemistry (bubble-water), 2) aqueous aerosol ozonation (gas-water droplet), and 3) electrolytic hydrogen production and simultaneous organic oxidation (water-metal/semiconductor). Direct interfacial analysis under environmentally relevant conditions is difficult, since most surface-specific techniques require relatively `extreme' conditions. Thus, the experimental investigations here focus on the development of chemical reactors and analytical techniques for the completion of time/concentration-dependent measurements of reactants and their products. Kinetic modeling, estimations, and/or correlations were used to extract information on interfacially relevant processes. We found that interfacial chemistry was determined to be the rate-limiting step to a subsequent series of relatively fast homogeneous reactions, for example: 1) Pyrolytic cleavage of the ionic headgroup of perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) adsorbed to cavitating bubble-water interfaces during sonolysis was the rate-determining step in transformation to their inorganic constituents carbon monoxide, carbon dioxide, and fluoride; 2) ozone oxidation of aqueous iodide to hypoiodous acid at the aerosol-gas interface is the rate-determining step in the oxidation of bromide and chloride to dihalogens; 3) Electrolytic oxidation of anodic titanol surface groups is rate-limiting for the overall oxidation of organics by the dichloride radical. We also found chemistry unique to the interface, for example: 1

    The TMT Software System consists of software components that interact with one another through a software infrastructure called TMT Common Software (CSW). CSW consists of software services and library code that is used by developers to create the subsystems and components that participate in the software system. CSW also defines the types of components that can be constructed and their roles. The use of common component types and shared middleware services allows standardized software interfaces for the components. A software system called the TMT Interface Database System was constructed to support the documentation of the interfaces for components based on CSW. The programmer describes a subsystem and each of its components using JSON-style text files. A command interface file describes each command a component can receive and any commands a component sends. The event interface files describe status, alarms, and events a component publishes and status and events subscribed to by a component. A web application was created to provide a user interface for the required features. Files are ingested into the software system's database. The user interface allows browsing subsystem interfaces, publishing versions of subsystem interfaces, and constructing and publishing interface control documents that consist of the intersection of two subsystem interfaces. All published subsystem interfaces and interface control documents are versioned for configuration control and follow the standard TMT change control processes. Subsystem interfaces and interface control documents can be visualized in the browser or exported as PDF files.

    Neural prostheses are technical systems that interface nerves to treat the symptoms of neurological diseases and to restore sensory of motor functions of the body. Success stories have been written with the cochlear implant to restore hearing, with spinal cord stimulators to treat chronic pain as well as urge incontinence, and with deep brain stimulators in patients suffering from Parkinson's disease. Highly complex neural implants for novel medical applications can be miniaturized either by means of precision mechanics technologies using known and established materials for electrodes, cables, and hermetic packages or by applying microsystems technologies. Examples for both approaches will be introduced and discussed. Electrode arrays for recording of electrocorticograms during presurgical epilepsy diagnosis have been manufactured using approved materials and a marking laser to achieve an integration density that is adequate in the context of brain machine interfaces, e.g. on the motor cortex. Microtechnologies have to be used for further miniaturization to develop polymer-based flexible and light weighted electrode arrays to interface the peripheral and central nervous system. Polyimide as substrate and insulation material will be discussed as well as several application examples for nerve interfaces like cuffs, filament like electrodes and large arrays for subdural implantation.

    Modern military forces assume that computer-based information is reliable, timely, available, usable, and shared. The importance of computer-based information is based on the assumption that {open_quotes}shared situation awareness, coupled with the ability to conduct continuous operations, will allow information age armies to observe, decide, and act faster, more correctly and more precisely than their enemies.{close_quotes} (Sullivan and Dubik 1994). Human-Computer Interface (HCI) design standardization is critical to the realization of the previously stated assumptions. Given that a key factor of a high-performance, high-reliability system is an easy-to-use, effective design of the interface between the hardware, software, and the user, it follows logically that the interface between the computer and the military user is critical to the success of the information-age military. The proliferation of computer technology has resulted in the development of an extensive variety of computer-based systems and the implementation of varying HCI styles on these systems. To accommodate the continued growth in computer-based systems, minimize HCI diversity, and improve system performance and reliability, the U.S. Department of Defense (DoD) is continuing to adopt interface standards for developing computer-based systems.

  11. Gluing Soft Interfaces by Nanoparticles

    Science.gov (United States)

    Cao, Zhen; Dobrynin, Andrey

    Using a combination of the molecular dynamics simulations and scaling analysis we studied reinforcement of interface between two soft gel-like materials by spherical nanoparticles. Analysis of the simulations shows that the depth of penetration of a nanoparticle into a gel is determined by a balance of the elastic energy of the gel and nanoparticle deformations and the surface energy of nanoparticle/gel interface. In order to evaluate work of adhesion of the reinforced interface, the potential of mean force for separation of two gels was calculated. These simulations showed that the gel separation proceeds through formation of necks connecting nanoparticle with two gels. The shapes of the necks are controlled by a fine interplay between nanoparticle/gel surface energies and elastic energy of the neck deformation. Our simulations showed that by introducing nanoparticles at soft interfaces, the work required for separation of two gels could be 10-100 times larger than the work of adhesion between two gels without nanoparticle reinforcement. These results provide insight in understanding the mechanism of gluing soft gels and biological tissues by nano- and micro-sized particles. NSF DMR-1409710.

    2012-05-01

    This research is aimed to create a new and robust family of convective schemes to capture the interface between the dispersed and the carrier phases in a spray without the need to build up the interface boundary. The selection of the Weighted Average Flux (WAF) scheme is due to this scheme being designed to deal with random flux scheme which is second-order accurate in space and time. The convective flux in each cell face utilizes the WAF scheme blended with Switching Technique for Advection and Capturing of Surfaces (STACS) scheme for high resolution flux limiters. In the next step, the high resolution scheme is blended with the WAF scheme to provide the sharpness and boundedness of the interface by using switching strategy. In this work, the Eulerian-Eulerian framework of non-reactive turbulent spray is set in terms of theoretical proposed methodology namely spray moments of drop size distribution, presented by Beck and Watkins [1]. The computational spray model avoids the need to segregate the local droplet number distribution into parcels of identical droplets. The proposed scheme is tested on capturing the spray edges in modelling hollow cone sprays without need to reconstruct two-phase interface. A test is made on simple comparison between TVD scheme and WAF scheme using the same flux limiter on convective flow hollow cone spray. Results show the WAF scheme gives a better prediction than TVD scheme. The only way to check the accuracy of the presented models is by evaluating the spray sheet thickness.

  15. Dissociation of charge-transfer states at donor-acceptor interfaces of organic heterojunctions

    Inche Ibrahim, M. L.

    2017-02-01

    The dissociation of charge-transfer (CT) states into free charge carriers at donor-acceptor (DA) interfaces is an important step in the operation of organic solar cells and related devices. In this paper, we show that the effect of DA morphology and architecture means that the directions of CT states (where a CT state’s direction is defined as the direction from the electron to the hole of the CT state) may deviate from the direction of the applied electric field. The deviation means that the electric field is not fully utilized to assist, and could even hinder the dissociation process. Furthermore, we show that the correct charge carrier mobilities that should be used to describe CT state dissociation are the actual mobilites at DA interfaces. The actual mobilities are defined in this paper, and in general are not the same as the mobilities that are used to calculate electric currents which are the mobilites along the direction of the electric field. Then, to correctly describe CT state dissociation, we modify the widely used Onsager-Braun (OB) model by including the effect of DA morphology and architecture, and by employing the correct mobilities. We verify that when the modified OB model is used to describe CT state dissociation, the fundamental issues that concern the original OB model are resolved. This study demonstrates that DA morphology and architecture play an important role by strongly influencing the CT state dissociation as well as the mobilites along the direction of the electric field.

    2004-01-01

    Brush/fin thermal interfaces are being developed to increase heat-transfer efficiency and thereby enhance the thermal management of orbital replaceable units (ORUs) of electronic and other equipment aboard the International Space Station. Brush/fin thermal interfaces could also be used to increase heat-transfer efficiency in terrestrial electronic and power systems. In a typical application according to conventional practice, a replaceable heat-generating unit includes a mounting surface with black-anodized metal fins that mesh with the matching fins of a heat sink or radiator on which the unit is mounted. The fins do not contact each other, but transfer heat via radiation exchange. A brush/fin interface also includes intermeshing fins, the difference being that the gaps between the fins are filled with brushes made of carbon or other fibers. The fibers span the gap between intermeshed fins, allowing heat transfer by conduction through the fibers. The fibers are attached to the metal surfaces as velvet-like coats in the manner of the carbon fiber brush heat exchangers described in the preceding article. The fiber brushes provide both mechanical compliance and thermal contact, thereby ensuring low contact thermal resistance. A certain amount of force is required to intermesh the fins due to sliding friction of the brush s fiber tips against the fins. This force increases linearly with penetration distance, reaching 1 psi (6.9 kPa) for full 2-in. (5.1 cm) penetration for the conventional radiant fin interface. Removal forces can be greater due to fiber buckling upon reversing the sliding direction. This buckling force can be greatly reduced by biasing the fibers at an angle perpendicularly to the sliding direction. Means of containing potentially harmful carbon fiber debris, which is electrically conductive, have been developed. Small prototype brush/fin thermal interfaces have been tested and found to exhibit temperature drops about onesixth of that of conventional

    A technique for conforming an interface between a first mesh and a second mesh is disclosed. A first interface surface in the first mesh and a second interface surface in the second mesh residing along the interface are identified. The first and second interface surfaces are initially non-conforming along the interface. Chords within the first and second interface surfaces that fall within a threshold separation distance of each other are paired. Sheets having chords that reside within the first or second interface surfaces are recursively inserted into or extracted from one or both of the first and second meshes until all remaining chords within the first interface surface are paired with corresponding chords in the second interface surface and all remaining chords within the second interface surface are paired with corresponding chords in the first interface surface.

  20. MIB Galerkin method for elliptic interface problems

    Xia, Kelin; Zhan, Meng; Wei, Guo-Wei

    2014-01-01

    Summary Material interfaces are omnipresent in the real-world structures and devices. Mathematical modeling of material interfaces often leads to elliptic partial differential equations (PDEs) with discontinuous coefficients and singular sources, which are commonly called elliptic interface problems. The development of high-order numerical schemes for elliptic interface problems has become a well defined field in applied and computational mathematics and attracted much attention in the past decades. Despite of significant advances, challenges remain in the construction of high-order schemes for nonsmooth interfaces, i.e., interfaces with geometric singularities, such as tips, cusps and sharp edges. The challenge of geometric singularities is amplified when they are associated with low solution regularities, e.g., tip-geometry effects in many fields.

    Material interfaces are omnipresent in the real-world structures and devices. Mathematical modeling of material interfaces often leads to elliptic partial differential equations (PDEs) with discontinuous coefficients and singular sources, which are commonly called elliptic interface problems. The development of high-order numerical schemes for elliptic interface problems has become a well defined field in applied and computational mathematics and attracted much attention in the past decades. Despite of significant advances, challenges remain in the construction of high-order schemes for nonsmooth interfaces, i.e., interfaces with geometric singularities, such as tips, cusps and sharp edges. The challenge of geometric singularities is amplified when they are associated with low solution regularities, e.g., tip-geometry effects in many fields. The present work introduces a matched interface and boundary (MIB) Galerkin method for solving two-dimensional (2D) elliptic PDEs with complex interfaces, geometric singularities and low solution regularities. The Cartesian grid based triangular elements are employed to avoid the time consuming mesh generation procedure. Consequently, the interface cuts through elements.

  2. Ionic Structure at Dielectric Interfaces

    Jing, Yufei

    The behavior of ions in liquids confined between macromolecules determines the outcome of many nanoscale assembly processes in synthetic and biological materials such as colloidal dispersions, emulsions, hydrogels, DNA, cell membranes, and proteins. Theoretically, the macromolecule-liquid boundary is often modeled as a dielectric interface and an important quantity of interest is the ionic structure in a liquid confined between two such interfaces. The knowledge gleaned from the study of ionic structure in such models can be useful in several industrial applications, such as biosensors, lithium-ion batteries double-layer supercapacitors for energy storage and seawater desalination. Electrostatics plays a critical role in the development of such functional materials. Many of the functions of these materials, result from charge and composition heterogeneities. There are great challenges in solving electrostatics problems in heterogeneous media with arbitrary shapes because electrostatic interactions remains unknown but depend on the particular density of charge distributions. Charged molecules in heterogeneous media affect the media's dielectric response and hence the interaction between the charges is unknown since it depends on the media and on the geometrical properties of the interfaces. To determine the properties of heterogeneous systems including crucial effects neglected in classical mean field models such as the hard core of the ions, the dielectric mismatch and interfaces with arbitrary shapes. The effect of hard core interactions accounts properly for short range interactions and the effect of local dielectric heterogeneities in the presence of ions and/or charged molecules for long-range interactions are both analyzed via an energy variational principle that enables to update charges and the medium's response in the same simulation time step. In particular, we compute the ionic structure in a model system of electrolyte confined by two planar dielectric

    Full Text Available Trata-se de compreender os pressupostos da filosofia concreta pretendida por Johann Gottfried Herder (1744-1803 em uma série de textos redigidos durante as décadas de 1760-70. Se, por um lado, Herder demonstra afinidade com a mesma harmonia preestabelecida que está na base de leibnizianos como Gottsched e Baumgarten, por outro, ele aprofunda a discussão sobre a origem do conhecimento humano ao reduzir a importância de juízos de valor universal e acentuar a necessidade de uma aproximação constante das sensações que se agitam obscuramente no fundo da alma. Disso resulta uma concepção inusitada de sabedoria, a qual depende de uma renúncia à posse confortável de conhecimentos abstratos e da aceitação da natureza cambiante e apenas parcialmente perscrutável daquilo que nos move. Se com isso perde-se a certeza, abre-se em contrapartida uma dimensão essencialmente ativa e sensível de realização no mundo.

Existem três tipos de labirintos: o labirinto clássico, o maneirístico, e a rede. O clássico é unicursal. Assim que se entra, a única coisa que se pode fazer é chegar ao centro e, do centro, só o que se pode fazer é encontrar uma saída. O maneirístico propõe escolhas alternativas. Todos os percursos levam a um ponto morto, com exceção de um que leva à saída. Na rede, cada ponto pode ter conexão com qualquer outro ponto. Se os labirintos anteriores têm um interior e um exterior, a rede, extensível ao infinito, não tem nem um dentro nem um fora.

    Full Text Available Abstract Background ACPYPE (or AnteChamber PYthon Parser interfacE is a wrapper script around the ANTECHAMBER software that simplifies the generation of small molecule topologies and parameters for a variety of molecular dynamics programmes like GROMACS, CHARMM and CNS. It is written in the Python programming language and was developed as a tool for interfacing with other Python based applications such as the CCPN software suite (for NMR data analysis and ARIA (for structure calculations from NMR data. ACPYPE is open source code, under GNU GPL v3, and is available as a stand-alone application at http://www.ccpn.ac.uk/acpype and as a web portal application at http://webapps.ccpn.ac.uk/acpype. Findings We verified the topologies generated by ACPYPE in three ways: by comparing with default AMBER topologies for standard amino acids; by generating and verifying topologies for a large set of ligands from the PDB; and by recalculating the structures for 5 protein–ligand complexes from the PDB. Conclusions ACPYPE is a tool that simplifies the automatic generation of topology and parameters in different formats for different molecular mechanics programmes, including calculation of partial charges, while being object oriented for integration with other applications.

  14. The ATLAS PanDA Monitoring System and its Evolution

    Science.gov (United States)

    Klimentov, A.; Nevski, P.; Potekhin, M.; Wenaus, T.

    2011-12-01

    The PanDA (Production and Distributed Analysis) Workload Management System is used for ATLAS distributed production and analysis worldwide. The needs of ATLAS global computing imposed challenging requirements on the design of PanDA in areas such as scalability, robustness, automation, diagnostics, and usability for both production shifters and analysis users. Through a system-wide job database, the PanDA monitor provides a comprehensive and coherent view of the system and job execution, from high level summaries to detailed drill-down job diagnostics. It is (like the rest of PanDA) an Apache-based Python application backed by Oracle. The presentation layer is HTML code generated on the fly in the Python application which is also responsible for managing database queries. However, this approach is lacking in user interface flexibility, simplicity of communication with external systems, and ease of maintenance. A decision was therefore made to migrate the PanDA monitor server to Django Web Application Framework and apply JSON/AJAX technology in the browser front end. This allows us to greatly reduce the amount of application code, separate data preparation from presentation, leverage open source for tools such as authentication and authorization mechanisms, and provide a richer and more dynamic user experience. We describe our approach, design and initial experience with the migration process.

    2004-01-01

    Observational evidence for anisotropy in supernovae (SN) and their phenomenological connection to jetted sources such as gamma-ray bursts^Mhave revived considerations of the role magnetohydrodynamic outflows might play therein. Understanding the types of dynamos that might operate in supernova progenitors is therefore relevant. In contrast to previous work, here we study an ``interface dynamo'' for the conditions of a rapidly rotating neutron star surrounded by a convective envelope. Such dynamos have been studied for the Sun, naked white dwarfs,and post-AGB stars, where analogous configurations of strong shear layers surrounded by convective envelopes are present. The interface dynamo provides estimates of large-scale poloidal and toroidal fields, whose product enters the Poynting flux. Because the poloidal field is much weaker than the toroidal magnetic field, the actual average Poynting flux is lower than rough estimates which invoke the only the magnitude of the total magnetic energy. The lower value is s...

    This document describes the minimum interface that a (SOAP- or REST-based) web service requires to participate in the IVOA. Note that this is not required of standard VO services developed prior to this specification, although uptake is strongly encouraged on any subsequent revision. All new standard VO services, however, must feature a VOSI-compliant interface. This document has been produced by the Grid and Web Services Working Group. It has been reviewed by IVOA Members and other interested parties, and has been endorsed by the IVOA Executive Committee as an IVOA Recommendation. It is a stable document and may be used as reference material or cited as a normative reference from another document. IVOA's role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. This enhances the functionality and interoperability inside the Astronomical Community.

    2016-01-01

    This book covers the science of interfaces between an aqueous phase and a solid, another liquid or a gaseous phase, starting from the basic physical chemistry all the way to state-of-the-art research developments. Both experimental and theoretical methods are treated thanks to the contributions of a distinguished list of authors who are all active researchers in their respective fields. The properties of these interfaces are crucial for a wide variety of processes, products and biological systems and functions, such as the formulation of personal care and food products, paints and coatings, microfluidic and lab-on-a-chip applications, cell membranes, and lung surfactants. Accordingly, research and expertise on the subject are spread over a broad range of academic disciplines and industrial laboratories. This book brings together knowledge from these different places with the aim of fostering education, collaborations and research progress.

  18. Low latency asynchronous interface circuits

    Energy Technology Data Exchange (ETDEWEB)

    Sadowski, Greg

    2017-06-20

    In one form, a logic circuit includes an asynchronous logic circuit, a synchronous logic circuit, and an interface circuit coupled between the asynchronous logic circuit and the synchronous logic circuit. The asynchronous logic circuit has a plurality of asynchronous outputs for providing a corresponding plurality of asynchronous signals. The synchronous logic circuit has a plurality of synchronous inputs corresponding to the plurality of asynchronous outputs, a stretch input for receiving a stretch signal, and a clock output for providing a clock signal. The synchronous logic circuit provides the clock signal as a periodic signal but prolongs a predetermined state of the clock signal while the stretch signal is active. The asynchronous interface detects whether metastability could occur when latching any of the plurality of the asynchronous outputs of the asynchronous logic circuit using said clock signal, and activates the stretch signal while the metastability could occur.

  19. Active matter clusters at interfaces

    CERN Document Server

    Copenhagen, Katherine

    2016-01-01

    Collective and directed motility or swarming is an emergent phenomenon displayed by many self-organized assemblies of active biological matter such as clusters of embryonic cells during tissue development, cancerous cells during tumor formation and metastasis, colonies of bacteria in a biofilm, or even flocks of birds and schools of fish at the macro-scale. Such clusters typically encounter very heterogeneous environments. What happens when a cluster encounters an interface between two different environments has implications for its function and fate. Here we study this problem by using a mathematical model of a cluster that treats it as a single cohesive unit that moves in two dimensions by exerting a force/torque per unit area whose magnitude depends on the nature of the local environment. We find that low speed (overdamped) clusters encountering an interface with a moderate difference in properties can lead to refraction or even total internal reflection of the cluster. For large speeds (underdamped), wher...

    Dhowre, Hala S; Rajput, Sunil; Russell, Noah A; Zelzer, Mischa

    2015-01-01

    Major design aspects for novel biomaterials are driven by the desire to mimic more varied and complex properties of a natural cellular environment with man-made materials. The development of stimulus responsive materials makes considerable contributions to the effort to incorporate dynamic and reversible elements into a biomaterial. This is particularly challenging for cell-material interactions that occur at an interface (biointerfaces); however, the design of responsive biointerfaces also presents opportunities in a variety of applications in biomedical research and regenerative medicine. This review will identify the requirements imposed on a responsive biointerface and use recent examples to demonstrate how some of these requirements have been met. Finally, the next steps in the development of more complex biomaterial interfaces, including multiple stimuli-responsive surfaces, surfaces of 3D objects and interactive biointerfaces will be discussed.

  3. Ultrafast Electron Transfer at Organic Semiconductor Interfaces: Importance of Molecular Orientation

    KAUST Repository

    Ayzner, Alexander L.

    2015-01-02

    © 2014 American Chemical Society. Much is known about the rate of photoexcited charge generation in at organic donor/acceptor (D/A) heterojunctions overaged over all relative arrangements. However, there has been very little experimental work investigating how the photoexcited electron transfer (ET) rate depends on the precise relative molecular orientation between D and A in thin solid films. This is the question that we address in this work. We find that the ET rate depends strongly on the relative molecular arrangement: The interface where the model donor compound copper phthalocyanine is oriented face-on with respect to the fullerene C60 acceptor yields a rate that is approximately 4 times faster than that of the edge-on oriented interface. Our results suggest that the D/A electronic coupling is significantly enhanced in the face-on case, which agrees well with theoretical predictions, underscoring the importance of controlling the relative interfacial molecular orientation.

  5. Vibrational spectroscopy of water interfaces

    Du, Quan [Univ. of California, Berkeley, CA (United States)

    1994-12-01

    The second order nonlinear optical processes of second harmonic generation and sum frequency generation are powerful and versatile tools for studying all kinds of surfaces. They possess unusual surface sensitivity due to the symmetry properties of the second order nonlinear susceptibility. The technique of infrared-visible sum frequency generation (SFG) is particularly attractive because it offers a viable way to do vibrational spectroscopy on any surfaces accessible to light with submonolayer sensitivity. In this thesis, the author applies SFG to study a number of important water interfaces. At the air/water interface, hydrophobic solid/water and liquid/water interfaces, it was found that approximately 25% of surface water molecules have one of their hydrogen pointing away from the liquid water. The large number of unsatisfied hydrogen bonds contributes significantly to the large interfacial energy of the hydrophobic surfaces. At the hydrophilic fused quartz/water interface and a fatty acid monolayer covered water surface, the structure and orientation of surface water molecules are controlled by the hydrogen bonding of water molecules with the surface OH groups and the electrostatic interaction with the surface field from the ionization of surface groups. A change of pH value in the bulk water can significantly change the relative importance of the two interactions and cause a drastic change in orientation of the surface water molecules. SFG has also been applied to study the tribological response of some model lubricant films. Monolayers of Langmuir-Blodgett films were found to disorder orientationaly under mildly high pressure and recover promptly upon removal of the applied pressure.

  8. The Interface Theory of Perception.

    Science.gov (United States)

    Hoffman, Donald D; Singh, Manish; Prakash, Chetan

    2015-12-01

    Perception is a product of evolution. Our perceptual systems, like our limbs and livers, have been shaped by natural selection. The effects of selection on perception can be studied using evolutionary games and genetic algorithms. To this end, we define and classify perceptual strategies and allow them to compete in evolutionary games in a variety of worlds with a variety of fitness functions. We find that veridical perceptions--strategies tuned to the true structure of the world--are routinely dominated by nonveridical strategies tuned to fitness. Veridical perceptions escape extinction only if fitness varies monotonically with truth. Thus, a perceptual strategy favored by selection is best thought of not as a window on truth but as akin to a windows interface of a PC. Just as the color and shape of an icon for a text file do not entail that the text file itself has a color or shape, so also our perceptions of space-time and objects do not entail (by the Invention of Space-Time Theorem) that objective reality has the structure of space-time and objects. An interface serves to guide useful actions, not to resemble truth. Indeed, an interface hides the truth; for someone editing a paper or photo, seeing transistors and firmware is an irrelevant hindrance. For the perceptions of H. sapiens, space-time is the desktop and physical objects are the icons. Our perceptions of space-time and objects have been shaped by natural selection to hide the truth and guide adaptive behaviors. Perception is an adaptive interface.

    2016-12-01

    Cuprate high-temperature superconductors consist of two quasi-two-dimensional (2D) substructures: CuO2 superconducting layers and charge reservoir layers. The superconductivity is realized by charge transfer from the charge reservoir layers into the superconducting layers without chemical dopants and defects being introduced into the latter, similar to modulation-doping in the semiconductor superlattices of AlGaAs/GaAs. Inspired by this scheme, we have been searching for high-temperature superconductivity in ultra-thin films of superconductors epitaxially grown on semiconductor/oxide substrates since 2008. We have observed interface-enhanced superconductivity in both conventional and unconventional superconducting films, including single atomic layer films of Pb and In on Si substrates and single unit cell (UC) films of FeSe on SrTiO3 (STO) substrates. The discovery of high-temperature superconductivity with a superconducting gap of ∼20 meV in 1UC-FeSe/STO has stimulated tremendous interest in the superconductivity community, for it opens a new avenue for both raising superconducting transition temperature and understanding the pairing mechanism of unconventional high-temperature superconductivity. Here, we review mainly the experimental progress on interface-enhanced superconductivity in the three systems mentioned above with emphasis on 1UC-FeSe/STO, studied by scanning tunneling microscopy/spectroscopy, angle-resolved photoemission spectroscopy and transport experiments. We discuss the roles of interfaces and a possible pairing mechanism inferred from these studies.

    Handheld technology finds slowly its place in the healthcare world. Some clinicians already use intensively dedicated mobile applications to consult clinical references. However, handheld technology hasn't still broadly embraced to the core of the healthcare business, the hospitals. The weak penetration of handheld technology in the hospitals can be partly explained by the caution of stakeholders that must be convinced about the efficiency of these tools before going forward. In a domain where temporal constraints are increasingly strong, caregivers cannot loose time on playing with gadgets. All users are not comfortable with tactile manipulations and the lack of dedicated peripheral complicates entering data for novices. Stakeholders must be convinced that caregivers will be able to master handheld devices. In this paper, we make the assumption that the proper design of an interface may influence users' performances to record information. We are also interested to find out whether users increase their efficiency when using handheld tools repeatedly. To answer these questions, we have set up a field study to compare users' performances on three different user interfaces while recording vital signs. Some user interfaces were familiar to users, and others were totally innovative. Results showed that users' familiarity with smartphone influences their performances and that users improve their performances by repeating a task.

    Using atomic scale models and interface defect theory, we first classify interface structures into a few types with respect to geometrical factors, then study the interfacial shear response and further simulate the dislocation-interface interactions using molecular dynamics. The results show that the atomic scale structural characteristics of both heterophases and homophases interfaces play a crucial role in (i) their mechanical responses and (ii) the ability of incoming lattice dislocations to transmit across them.

    We present the implementation of a programmable atom-photon quantum interface, employing a single trapped +40Ca ion and single photons. Depending on its mode of operation, the interface serves as a bidirectional atom-photon quantum-state converter, as a source of entangled atom-photon states, or as a quantum frequency converter of single photons. The interface lends itself particularly to interfacing ions with spontaneous parametric down-conversion-based single-photon or entangled-photon-pair sources.

  16. Roles and Delegation of Authority (R/DA) System

    1999-11-01

    The processes of defining managerial roles and providing for delegation of authority are essential to any enterprise. At most large organizations, these processes are defined in policy manuals and through sets of standard operating procedures for many, if not all, business and administrative functions. Many of these staff-initiated, administrative functions require the routing of documents for approval to one or more levels of management. These employee-oriented, back office types of workflows tend to require more flexibility in determining to whom these documents should go to, while, at the same time, providing the responsible parties with the flexibility to delegate their approval authority or allow others to review their work. Although this practice is commonplace in manual, paper-based processes that exist in many organizations, it is difficult to provide the same flexibility in the more structured, electronic-based, workflow systems. The purpose of this report is to present a framework or architecture for creating a R/DA system and provide some insights associated with its design and utilization. To improve understanding and clarify subsequent discussion, the goals and requirements for the major R/DA system components, namely, the database and interface modules, are initially presented along with the identification of important concepts and the definition of critical terms. Next high-level functions relating the types of inputs to the outputs of the R/DA interface module are introduced and discussed. Then the relationships between the major R/DA modules and the primary components associated with its creation and maintenance are presented and analyzed. Finally, some conclusions are drawn relative to the advantages associated with developing a R/DA system for use in implementing an enterprise-wide, work-facilitating information system.

    2014-07-01

    The da Vinci surgical system was developed by Intuitive Surgical Inc. in the United States as an endoscopic surgical device to assist remote control surgeries. In 1998, the Da Vinci system was first used for cardiothoracic procedures. Currently a combination of robot-assisted internal thoracic artery harvest together with coronary artery bypass grafting (CABG) through a mini-incision (ThoraCAB) or totally endoscopic procedures including anastomoses under robotic assistance (TECAB) are being conducted for the treatment of coronary artery diseases. With the recent advances in catheter interventions, hybrid procedures combining catheter intervention with ThoraCAB or TECAB are anticipated in the future.On the other hand, with the decrease in number of coronary artery bypass surgeries, the share of valvular surgeries is expected to increase in the future. Among them, mitral valvuloplasty for mitral regurgitation is anticipated to be conducted mainly by low-invasive procedures, represented by minimally invasive cardiac surgery( MICS) and robot-assisted surgery. Apart from the intrinsic good surgical view, robotic-assisted systems offer additional advantages of the availability of an amplified view and the easy to observe the mitral valve in the physiological position. Thus, robotic surgical surgeries that make complicated procedures easier are expected to accomplish further developments in the future. Furthermore, while the number of surgeries for atrial septal defects has decreased dramatically following the widespread use of Amplatzer septal occluder, robotic surgery may become a good indication for cases in which the Amplatzer device is not indicated. In Japan, clinical trial of the da Vinci robotic system for heart surgeries has been completed. Statutory approval of the da Vinci system for mitral regurgitation and atrial septal defects is anticipated in the next few years.

    2009-07-13

    Soft matter consists of complex molecules that can undergo drastic structural transformations under mild changes of chemical and physical conditions. Since a wide variety of chemical, physical and biological processes occur at soft matter interfaces, they can exhibit complex behavior. This is even more so for interfaces of colloidal soft matter since the relative amount of interface material increases by orders of magnitude. Herein, we focus on new developments that enable us to obtain detailed molecular structural changes in the topmost molecular layers of soft matter interfaces composed of complex bio-molecules. In particular, the possibilities to probe interfaces of colloidal soft matter systems are discussed.

    The mechanical integrity of silicon/silicon nitride interfaces is of great importance in their applications in micro electronics and solar cells. Large-scale molecular dynamics simulations are an excellent tool to study mechanical and structural failure of interfaces subjected to externally applied stresses and strains. When pulling the system parallel to the interface, cracks in silicon nitride and slip and pit formation in silicon are typical failure mechanisms. Hypervelocity impact perpendicular to the interface plane leads to structural transformation and delamination at the interface. Influence of system temperature, strain rate, impact velocity, and system size on type and characteristics of failure will be discussed.

    Benjamin, R.F. [Los Alamos National Lab., NM (United States). Dynamic Experimentation Div.

    1997-02-01

    The discipline of materials science and engineering often involves understanding and controlling properties of interfaces. The authors address the challenge of educating students about properties of interfaces, particularly dynamic properties and effects of unstable interfaces. A series of simple, inexpensive, hands-on activities about fluid interfaces provides students with a testbed to develop intuition about interface dynamics. The experiments highlight the essential role of initial interfacial perturbations in determining the dynamic response of the interface. The experiments produce dramatic, unexpected effects when initial perturbations are controlled and inhibited. These activities help students to develop insight about unstable interfaces that can be applied to analogous problems in materials science and engineering. The lessons examine ``Rayleigh-Taylor instability,`` an interfacial instability that occurs when a higher-density fluid is above a lower-density fluid.

  18. Tailoring thermal interfaces with nanomaterials

    Science.gov (United States)

    Seshadri, Indira

    Thermal interfaces are key to ensure the reliable performance of many semiconductor, energy and electronic systems. High thermal conductivity (k), low elastic modulus (E) interface materials are required to dissipate heat and relieve thermo-mechanical stresses. The aim of this thesis is to develop compliant, high k nanocomposite materials for thermal interface applications utilizing nanostructured networks. Realizing high k nanocomposites is a challenge because of difficulties in incorporating high fractions of uniformly dispersed nanofillers and countering low filler-matrix interfacial conductance, while retaining a low elastic modulus. In this thesis, it is demonstrated that these issues are obviated by using thesis reveals a critical correlation between the rheological behavior of a high k gold-nanowire-filled polydimethylsiloxane nanocomposite and its thermal contact conductance with copper. At a critical filler fraction, an abrupt increase in the nanocomposite k is accompanied by a liquid-solid transition and a multifold decrease in Gc. These concurrent changes are attributed to nanowire percolation network formation and pre-cure polymer gelation that inhibits the formation of conformal void-free interfaces. These findings will be important for designing processing sequences to realize heterointerfaces with nanowire filled high k nanocomposite materials. Another important finding of this thesis is that nanowire networks can result in mechanical softening of polymer matrices. It is demonstrated that silver nanowire fillers result in a three-fold decrease in viscoelastic storage modulus of polydimethylsiloxane composites above a low critical filler fraction of ~0.5%, contrary to theoretical predictions presaging a modulus increase. Similar fractions of silver nanocube fillers result in no such observable effects. Rheology measurements and calorimetric kinetics analyses reveal that high surface area nanowire filler percolation networks curtail macromolecular

    We have developed a mature laboratory at Sandia to measure interfacial rheology, using a combination of home-built, commercially available, and customized commercial tools. An Interfacial Shear Rheometer (KSV ISR-400) was modified and the software improved to increase sensitivity and reliability. Another shear rheometer, a TA Instruments AR-G2, was equipped with a du Nouey ring, bicone geometry, and a double wall ring. These interfacial attachments were compared to each other and to the ISR. The best results with the AR-G2 were obtained with the du Nouey ring. A Micro-Interfacial Rheometer (MIR) was developed in house to obtain the much higher sensitivity given by a smaller probe. However, it was found to be difficult to apply this technique for highly elastic surfaces. Interfaces also exhibit dilatational rheology when the interface changes area, such as occurs when bubbles grow or shrink. To measure this rheological response we developed a Surface Dilatational Rheometer (SDR), in which changes in surface tension with surface area are measured during the oscillation of the volume of a pendant drop or bubble. All instruments were tested with various surfactant solutions to determine the limitations of each. In addition, foaming capability and foam stability were tested and compared with the rheology data. It was found that there was no clear correlation of surface rheology with foaming/defoaming with different types of surfactants, but, within a family of surfactants, rheology could predict the foam stability. Diffusion of surfactants to the interface and the behavior of polyelectrolytes were two subjects studied with the new equipment. Finally, surface rheological terms were added to a finite element Navier-Stokes solver and preliminary testing of the code completed. Recommendations for improved implementation were given. When completed we plan to use the computations to better interpret the experimental data and account for the effects of the underlying bulk

    We analyze two intertwined and fundamental issues concerning computer-to-human communication in the multimodal interfaces: the interplay between sound and graphics, and the role of object persistence. Our observations lead us to introduce metawidgets as abstract entities capable of manifesting themselves to users as image, as sound, or as various combinations and/or sequences of the two media. We show examples of metawidgets in action, and discuss mechanisms for choosing among alternative media for metawidget instantiation. Finally, we describe a couple of experimental microworlds we have implemented to test out some of our ideas. 17 refs., 7 figs.

    Full Text Available Nosso objetivo é discutir a história da constituição de novos objetos no campo da Psicologia social brasileira, particularmente dos processos de urbanização, globalização, informatização da sociedade e suas interfaces com os processos de subjetivação. Tal discussão é resultado de uma pesquisa realizada nos resumos dos Anais dos Simpósios da Associação Nacional de Pesquisa e Pós-Graduação em Psicologia (ANPEPP, abrangendo o período de 1988 a 2010. Nossa metodologia propõe uma genealogia da Psicologia social brasileira. Utilizamos a perspectiva foucaultiana sobre a história, o conhecimento e as subjetividades como ferramentas teóricas e analíticas. A partir dessa análise, afirmamos a possibilidade de uma história da Psicologia social brasileira que não se escreve a partir dos seus grandes representantes ou vertentes teóricas, mas da constituição de novos problemas, objetos e campos de intervenção. Nesse sentido, buscamos acompanhar a constituição de seus múltiplos objetos e perspectivas, assinalando a não linearidade de seu desenvolvimento, mas suas controvérsias e rupturas.

    Ta/NiO/NiFe/Ta multilayers were prepared by rf reactive and dc magnetron sputter-ing. The exchange coupling field (Hex) between NiO and NiFe reached 120Oe. Thecomposition and chemical states at the interface region of NiO/NiFe were studied us-ing the x-ray photoelectron spectroscopy (XPS) and peak decomposition technique. Theresults show that there are two thermodynamically favorable reactions at NiO/NiFeinterface: NiO+Fe = Ni+FeO and 3NiO+2Fe 3Ni+Fe2 O3. The thickness of thechemical reaction as estimated by angle-resolved XPS was about 1-1.5nm. These in-terrace reaction products are magnetic defects, and we believe that the Hex and thecoereivity (He) of NiO/NiFe ave affected by these defects. Moreover, the results alsoshow that there is an "intermixing layer" at the Ta/NiO (and NiO/Ta) interface dueto a thermodynamically favorable reaction: 2Ta+5NiO=5Ni+Ta2O5. This interfacereaction has an effect on the exchange coupling as well. The thickness of the "inter-mixing layer" as estimated by XPS depth-profiles was about 8-10nm.

    A brain-computer interface (BCI) is a hardware and software communications system that permits cerebral activity alone to control computers or external devices. The immediate goal of BCI research is to provide communications capabilities to severely disabled people who are totally paralyzed or ‘locked in’ by neurological neuromuscular disorders, such as amyotrophic lateral sclerosis, brain stem stroke, or spinal cord injury. Here, we review the state-of-the-art of BCIs, looking at the different steps that form a standard BCI: signal acquisition, preprocessing or signal enhancement, feature extraction, classification and the control interface. We discuss their advantages, drawbacks, and latest advances, and we survey the numerous technologies reported in the scientific literature to design each step of a BCI. First, the review examines the neuroimaging modalities used in the signal acquisition step, each of which monitors a different functional brain activity such as electrical, magnetic or metabolic activity. Second, the review discusses different electrophysiological control signals that determine user intentions, which can be detected in brain activity. Third, the review includes some techniques used in the signal enhancement step to deal with the artifacts in the control signals and improve the performance. Fourth, the review studies some mathematic algorithms used in the feature extraction and classification steps which translate the information in the control signals into commands that operate a computer or other device. Finally, the review provides an overview of various BCI applications that control a range of devices. PMID:22438708

    Full Text Available Enterprise architecture frameworks define the goals of enterprise architecture in order to make business processes and IT operations more effective, and to reduce the risk of future investments. These enterprise architecture frameworks offer different architecture development methods that help in building enterprise architecture. In practice, the larger organizations become, the larger their enterprise architecture and IT become. This leads to an increasingly complex system of enterprise architecture development and maintenance. Application software architecture is one type of architecture that, along with business architecture, data architecture and technology architecture, composes enterprise architecture. From the perspective of integration, enterprise architecture can be considered a system of interaction between multiple examples of application software. Therefore, effective software integration is a very important basis for the future success of the enterprise architecture in question. This article will provide interface-based integration practice in order to help simplify the process of building such a software integration system. The main goal of interface-based software integration is to solve problems that may arise with software integration requirements and developing software integration architecture.

    Full Text Available Software quality is determined by assessing the characteristics that specify how it should work, which are verified through testing. If it were possible to touch, see, or measure software, it would be easier to analyze and prove its quality. Unfortunately, software is an intangible asset, which makes testing complex. This is especially true when software quality is not a question of particular functions that can be tested through a graphical user interface. The primary objective of software architecture is to design quality of software through modeling and visualization. There are many methods and standards that define how to control and manage quality. However, many IT software development projects still fail due to the difficulties involved in measuring, controlling, and managing software quality. Software quality failure factors are numerous. Examples include beginning to test software too late in the development process, or failing properly to understand, or design, the software architecture and the software component structure. The goal of this article is to provide an interface-based software testing technique that better measures software quality, automates software quality testing, encourages early testing, and increases the software’s overall testability

    2016-05-17

    Polydopamine (pDA) coatings afford tremendous versatility due to their capabilities to provide substrate-independent functionalization with a wide range of amine- and thiol-containing molecules. In this work, we developed a new and facile conjugation approach to the formation of β-amino carbonyl linkages between pDA and acrylate/acrylamide molecules via the aza-Michael reaction. Sulfobetaine acrylamide (SBAA), sulfobetaine methacrylate (SBMA), and poly(ethylene glycol) methacrylate (PEGMA) were employed to graft onto pDA films, giving rise to formation of antifouling coatings. Because of the universal adhesive property of pDA, the coating strategy was applied to different substrates, including TiO2, gold, SiO2, Nitinol alloy, polystyrene, and poly(dimethylsiloxane). The variation of surface chemistry and surface wettability upon pDA modification and subsequent conjugation was monitored with X-ray photoelectron spectroscopy (XPS) and water contact angle measurements. Antifouling properties of coatings were challenged by three common Gram-negative and Gram-positive bacteria. Cytocompatibility of the coatings with NIH-3T3 fibroblasts was accessed using MTT assay. The results showed that pDA coatings grafted with SBAA exhibited superhydrophilicity and excellent fouling resistance likely due to the high chemical reactivity of acrylamide, leading to high grafting density. In addition, dual functional coatings containing passive and active antibacterial components were constructed through the in situ deposition of antimicrobial agent, silver nanoparticles, in pDA, followed by the grafting of SBAA for bacterial repellence. The composite coatings allowed reducing adsorption of E. coli by >95%, while killing attached bacteria by up to 98% upon the releasing of Ag(+) ions as measured by inductively coupled plasma mass spectrometry. Consequently, this work paves a new avenue to the grafting strategy to engineer pDA and to the functional bioinspired antifouling interfaces in

    1965-09-01

    Full Text Available O estudo da dor é um capítulo do estudo das bases neurofisiológicas da sensação, pois a dor nada mais é que uma sensação de conteúdo desagradável originada por estímulos nocivos. Enquanto a função das outras modalidades sensoriais é informativa ou gnósica, a dor é de proteção. O estudo da fisiología da dor compreende o estudo dos receptores, dos estímulos, das vias, das estruturas do sistema nervoso central que partici- pam da fisiología da dor, da percepção dolorosa e das reações motoras e neurovegetativas. São analisados os receptores e as vias e discutidas sua especificidade, assim como a transmissão da dor rápida e lenta por vias nervosas diferentes até o córtex cerebral. É comentada a influência da atenção na intensidade da percepção dolorosa e, com base em estudos experimentais, é considerado que o circuito retículo-córtico-reticular seja indispensável para a percepção da dor. No tocante à patologia da dor é examinada a insensibilidade congênita à dor, sendo admitida a hipótese de que em algumas sinapses é modificado o esquema de impulsos que darão lugar à sensação dolorosa. É destacado o papel do lobo frontal como parte de um mecanismo pòtenciador que condiciona o sofrimento geral do paciente. A dor referida é explicada pela teoria da "convergência-projeção" de fibras viscerais com fibras cutâneas dolorosas sôbre o mesmo neurônio em algun ponto da via sensitiva. O resultado da hipofisectomia trazendo uma diminuição ou anulação da dor no câncer do seio abre debates em tôrno do papel dos hormônios na percepção dolorosa.

    Full Text Available Introdução: Os tumores cartilaginosos da laringe são raros, sendo a cartilagem cricóide a mais acometida. A raridade desses tumores tem como conseqüência experiência limitada e, portanto, o conhecimento a respeito destas neoplasias apresenta pontos obscuros. Objetivo: Apresentar os resultados cirúrgicos bem como o seguimento a longo prazo de 6 pacientes com tumores cartilaginosos da laringe, 4 condrossarcomas de baixa malignidade e 2 condromas. Forma de estudo: Retrospectivo não randomizado. Material e método: Cinco dos tumores acometiam a cartilagem cricóide e 1 a tireóide. Os pacientes foram submetidos a laringectomia parcial (4 e total (2, com seguimento de 6 a 30 anos (média-19,5 anos. Resultados: Nenhum dos pacientes apresentou metástase ou morte relacionada ao tumor. A sobrevida alcançada por 5 anos foi de 100% e a por 20 anos, 67%, sendo a comorbidade responsável por tal decréscimo. Conclusões: Nossos resultados reforçam o conceito de que a laringectomia conservadora seja a modalidade ideal de tratamento, reservando a ressecção total para tumores extensos ou casos de recorrência. Há indícios de que 5 anos pode não ser tempo suficiente para observar recorrência no condrossarcoma de baixo grau de malignidade.

    Full Text Available Esse artigo tem como objeto a difícil percepção da "diferença". Tema polêmico, o debate sobre as variedades culturais foi transformado, em meados do século XIX, em uma questão racial e, nesse sentido, vinculado às regularidades da biologia. Tecendo comparações entre os teóricos raciais brasileiros e os impasses mais contemporâneos, sobre a aferição de inteligência e capacidade, esse ensaio pretende provocar. Em pauta estarão as contradições que têm se destacado, mais recentemente, quando se opõem de um lado as etnicidades locais, de outro a tão propalada globalização. Tal qual dois lados de uma mesma moeda, a afirmação de identidades tem se mostrado tão evidente como o próprio estreitamento das relações internacionais. Mudam os termos do debate - de raça, para etnia -, mas, de alguma maneira, continuamos presos a uma lógica positiva de estabelecimento de hierarquias ontológicas.

    Full Text Available Resumo Ao discorrer sobre o “Futuro do Etnocentrismo”, este artigo parte da premissa de que a globalização, apesar de ter – em muitos casos – diminuído as diferenças entre povos, não tem amenizado os preconceitos e as formas de discriminação que ocorrem em nome dessas diferenças. Ele resgata a importância do antropólogo neste cenário lembrando que a diversidade cultural faz parte da sociedade complexa, remetendo-se não apenas a grupos étnicos ou nacionais bem delimitados, mas também a diferenças de geração, gênero, sexo e classe, entre outros. Neste contexto, a tolerância passiva de modos distantes de vida assim como a aceitação pragmática de nosso próprio paroquialismo são atitudes não somente intelectualmente desonestas mas também moralmente repreensíveis. É no encontro incômodo de subjetividades variantes na sua própria sociedade que o antropólogo define seu lugar.

  13. Reactive scalar field near the turbulent/non-turbulent interface in a planar jet with a second-order chemical reaction

    Science.gov (United States)

    Watanabe, T.; Sakai, Y.; Nagata, K.; Ito, Y.; Hayase, T.

    2014-10-01

    The reactive scalar field near the turbulent/non-turbulent (T/NT) interface is analyzed using a direct numerical simulation (DNS) of a planar jet with an isothermal second-order chemical reaction A + B → P. Reactants A and B are supplied from the jet and ambient flows, respectively. The DNS of the reactive jet is performed for Damköhler numbers Da = 0.1, 1, and 10. A visualization of the T/NT interface shows that most of the product P is contained in the turbulent region. The conditional mean concentrations of the reactive species change sharply near the T/NT interface. The width of the jump in the conditional mean concentration is almost independent of the chemical species and the Damköhler number. For the slow reaction (Da = 0.1), the conditional average of the chemical production rate gradually increases from the non-turbulent region toward the turbulent region. In contrast, the conditional average of the production rate for Da = 1 and 10 has a large peak value slightly inside the T/NT interface. The chemical reaction near the T/NT interface strongly depends on the interface orientation. The reactant A is deficient near the T/NT interface. The production rate is large near the interface toward which the deficient reactant A is frequently transported by the velocity fields. The transport due to the velocity relative to the interface movement strongly depends on the relationship between the interface geometry and the mean flow field. The dependence of the chemical reaction on the interface orientation becomes strong as Da increases. When the interface propagates toward the non-turbulent region, the reactant A and product P are contained in the turbulent region although the molecular diffusion and reaction contribute to the increase in the concentrations of A (non-reactive case) and P in the non-turbulent region. In contrast, the interface propagation toward the turbulent region leaves the fluids containing A and P in the non-turbulent region.

    Full Text Available RESUMO Este artigo apresenta, discute e exemplifica os rumos da pesquisa funcionalista em sua orientação mais recente, no diálogo com os estudos cognitivistas. Fruto dessa interrelação, destaca-se a abordagem construcional da gramática, na ênfase do pareamento função x forma que marca as expressões linguísticas. Além de apontar os ganhos teórico-metodológicos que tal diálogo tem trazido no âmbito do Funcionalismo, o artigo faz referência também às especificidades de ambas as vertentes teóricas e aos ajustes necessários a fim de que possam ser desenvolvidas pesquisas nessa interface. O tratamento da gramática em perspectiva holística e o rigor na detecção de propriedades de sentido e estrutura que marcam os usos linguísticos são considerados vieses positivos e promissores da pesquisa funcionalista de abordagem construcional.

The method using profilometry and in-plane x-ray diffraction does not take intermixing...... into account and yields an apparent interface stress of -8.46 +/- 0.99 J m(-2). However, observed discrepancies between model calculations and measured high-angle x-ray diffractograms indicate intermixing, and by use of the profilometry and sin(2) psi method the real interface stress value of -2.69 +/- 0.43 J...... to be inapplicable to interface stress determinations in systems exhibiting a modulation period-dependent stress-free lattice parameter. Finally, a deviation of the interface stress in the Au/Ni sample with the smallest modulation period as compared to specimens with larger bilayer lengths is observed...

    The secret to the success of mixed bulk heterojunctions (BHJs) in yielding highly efficient organic solar cells (OSCs) could reside in the molecular structures at their donor/acceptor (D/A) interfaces. In this study, we aimed to determine the effects of energy and charge cascade structures at the interfaces by using well-defined planar heterojunctions (PHJs) as a model system. The results showed that (1) the charge cascade structure enhanced VOC because it shuts down the recombination pathway through charge transfer (CT) state with a low energy, (2) the charge cascade layer having a wider energy gap than the bulk material decreased JSC because the diffusion of the excitons from the bulk to D/A interface was blocked; the energy of the cascade layers must be appropriately arranged for both the charges and the excitons, and (3) molecular intermixing in the cascade layer opened the recombination path through the low-energy CT state and decreased VOC. Based on these findings, we propose improved structures for D/A interfaces in BHJs.

    We present an interface area transport model required in tracking of mass, momentum, and energy exchange between dispersed and background materials. The basic transport equation has been rigorously derived from the volume fraction evolution equation. Interface area changes due to mass transport and local compression/expansion are included. The model is then simplified for the case in which the dispersed phase is composed of spheres of locally uniform size. A procedure for calculating advective flux with interface reconstruction has been suggested.

    For the last 15 years, many Eulerian codes have relied on a series of piecewise linear interface reconstruction algorithms developed by David Youngs. In a typical Youngs` method, the material interfaces were reconstructed based upon nearly cell values of volume fractions of each material. The interfaces were locally represented by linear segments in two dimensions and by pieces of planes in three dimensions. The first step in such reconstruction was to locally approximate an interface normal. In Youngs` 3D method, a local gradient of a cell-volume-fraction function was estimated and taken to be the local interface normal. A linear interface was moved perpendicular to the now known normal until the mass behind it matched the material volume fraction for the cell in question. But for distorted or nonorthogonal meshes, the gradient normal estimate didn`t accurately match that of linear material interfaces. Moreover, curved material interfaces were also poorly represented. The authors will present some recent work in the computation of more accurate interface normals, without necessarily increasing stencil size. Their estimate of the normal is made using an iterative process that, given mass fractions for nearby cells of known but arbitrary variable density, converges in 3 or 4 passes in practice (and quadratically--like Newton`s method--in principle). The method reproduces a linear interface in both orthogonal and nonorthogonal meshes. The local linear approximation is generally 2nd-order accurate, with a 1st-order accurate normal for curved interfaces in both two and three dimensional polyhedral meshes. Recent work demonstrating the interface reconstruction for curved surfaces will /be discussed.

    It is a known fact that swimmers behave differently near deformable soft tissues than when near a rigid surface. Motivated by this class of problems, we investigate swimming microorganisms near flexible walls. We calculate the speed of a n infinitely long swimmer near an interface between two viscous fluids. Part of the calculation of the speed is the calculation of the shape of the free boundary. The swimming speed is controlled by the competition between surface and viscous effects, where two limits are observed. When the surface tension vanishes, we get Taylor's result for a swimmer with no walls. When the surface tension is infinite, the problem is like that of a swimmer near a rigid wall.

    2014-01-01

    Vitreous role in the pathophysiology of retinal diseases has increased importantly over the recent years. This was possible using Optical Coherence Tomography which reviewed the way the vitreoretinal interface should be looked at and defined and classified new pathologies such as Vitreoretinal Traction Syndrome. Vitreous is not an empty space but an important anatomical structure with role in ocular physiology. With age biochemical changes occur so that vitreous starts to liquefy. Once the vitreous is liquefied (sinchisis) it collapses and passes in the retrohialoid space (sineresis). In complete PVD besides sinchisis there is a weakness of the adherence between the posterior cortex and ILM with total detachment of posterior cortex. Abnormal adhesions are associated with incomplete PVD. The definition and understanting of vitreoretinal pathology is an active and continuous process, PVD being the trigger of a lot of retinal pathologies: epiretinal membrane, macular hole, tractional macular oedema, VMTS, myopic traction maculopathy, exacerbations of exudative ARMD.

    2015-07-07

    We introduce a minimal theory of glass formation based on the ideas of molecular crowding and resultant string-like cooperative rearrangement, and address the effects of free interfaces. In the bulk case, we obtain a scaling expression for the number of particles taking part in cooperative strings, and we recover the Adam-Gibbs description of glassy dynamics. Then, by including thermal dilatation, the Vogel-Fulcher-Tammann relation is derived. Moreover, the random and string-like characters of the cooperative rearrangement allow us to predict a temperature-dependent expression for the cooperative length ξ of bulk relaxation. Finally, we explore the influence of sample boundaries when the system size becomes comparable to ξ. The theory is in agreement with measurements of the glass-transition temperature of thin polymer films, and allows quantification of the temperature-dependent thickness hm of the interfacial mobile layer.

  12. Electronic Interfacing with Living Cells

    Fleming, James T.

    The direct interfacing of living cells with inorganic electronic materials, components or systems has led to the development of two broad categories of devices that can (1) transduce biochemical signals generated by biological components into electrical signals and (2) transduce electronically generated signals into biochemical signals. The first category of devices permits the monitoring of living cells, the second, enables control of cellular processes. This review will survey this exciting area with emphasis on the fundamental issues and obstacles faced by researchers. Devices and applications that use both prokaryotic (microbial) and eukaryotic (mammalian) cells will be covered. Individual devices described include microbial biofuel cells that produce electricity, bioelectrical reactors that enable electronic control of cellular metabolism, living cell biosensors for the detection of chemicals and devices that permit monitoring and control of mammalian physiology.

    Nanofluidics has emerged recently in the footsteps of microfluidics, following the quest for scale reduction inherent to nanotechnologies. By definition, nanofluidics explores transport phenomena of fluids at nanometer scales. Why is the nanometer scale specific? What fluid properties are probed at nanometric scales? In other words, why does 'nanofluidics' deserve its own brand name? In this critical review, we will explore the vast manifold of length scales emerging for fluid behavior at the nanoscale, as well as the associated mechanisms and corresponding applications. We will in particular explore the interplay between bulk and interface phenomena. The limit of validity of the continuum approaches will be discussed, as well as the numerous surface induced effects occurring at these scales, from hydrodynamic slippage to the various electro-kinetic phenomena originating from the couplings between hydrodynamics and electrostatics. An enlightening analogy between ion transport in nanochannels and transport in doped semi-conductors will be discussed (156 references).

    Shestakov, Denis

    A huge portion of the Web known as the deep Web is accessible via search interfaces to myriads of databases on the Web. While relatively good approaches for querying the contents of web databases have been recently proposed, one cannot fully utilize them having most search interfaces unlocated. Thus, the automatic recognition of search interfaces to online databases is crucial for any application accessing the deep Web. This paper describes the architecture of the I-Crawler, a system for finding and classifying search interfaces. The I-Crawler is intentionally designed to be used in the deep web characterization surveys and for constructing directories of deep web resources.

    Neutron reflectometry can be used in various ways to investigate surfaces, interfaces and thin films of polymers. Its potential comes mostly from the possibilities offered by selective deuteration, where a particular component can be made visible with respect to its activity at the interface. In addition the depth resolution is much better than with most other direct techniques, and details of the profiles may be resolved. Several examples will be discussed including the segment diffusion at the interface between two polymer films, the determination of the narrow interfaces between incompatible polymer blends and the development of order in thin diblock copolymer films.

    1999-08-01

    Commercial display interfaces are currently transitioning from analog to digital. Although this transition is in the very early stages, the military needs to begin planning their own transition to digital. There are many problems with the analog interface in high-resolution display systems that are solved by changing to a digital interface. Also, display system cost can be lower with a digital interface to a high resolution display. Battelle is under contract with DARPA to develop an advanced Display Interface (ADI) to replace the analog RGB interfaces currently used in high definition workstation displays. The goal is to create a standard digital display interface for military applications that is based on emerging commercial standards. Support for military application- specific functionality is addressed, including display test and control. The main challenges to implementing a digital display interface are described, along with approaches to address the problems. Conceptual ADI architectures are described and contrasted. The current and emerging commercial standards for digital display interfaces are reviewed in detail. Finally, the tasks required to complete the ADI effort are outlined and described.

    Enhancement of two-fluid mixing was numericallystudied by tracking the multi-fluid interfaces. Level set equations were used to capture the interfaces, and flow field was obtained by upwind TVD scheme to solve 2D Eulerian equations. The boundary conditions at interface of two fluids are determined by Ghost fluid method (GFM). The distributions of fluid parameters, such as pressure and density, were got at different time steps.The results show that the method presented in this paper can track the density discontinuity perfectly. Superior to previous results, the density discontinuity remains sharper. Also, the mixing of fluids can be greatly enhanced by setting disturbances along the initial fluid interfaces.``

    Tests of interface between compacted clay and concrete were conducted systematically using interface simple shear test apparatus. The samples, having same dry density with different water content ratio, were prepared.Two types of concrete with different surface roughness, i.e., relatively smooth and relatively rough surface rough-ness, were also prepared. The main objectives of this paper are to show the effect of water content, normal stress and rough surface on the shear stress-shear displacement relationship of clay-concrete interface. The following were concluded in this study: 1) the interface shear sliding dominates the interface shear displacement behavior for both cases of relatively rough and smooth concrete surface except when the clay water content is greater than 16% for the case of rough concrete surface where the shear failure occurs in the body of the clay sample; 2) the results of interface shear strength obtained by direct shear test were different from that of simple shear test for the case of rough concrete surface; 3) two types of interface failure mechanism may change each other with different water content ratio; 4) the interface shear strength increases with increasing water content ratio especially for the case of clay-rough concrete surface interface.

  3. An interface energy density-based theory considering the coherent interface effect in nanomaterials

    Yao, Yin; Chen, Shaohua; Fang, Daining

    2017-02-01

    To characterize the coherent interface effect conveniently and feasibly in nanomaterials, a continuum theory is proposed that is based on the concept of the interface free energy density, which is a dominant factor affecting the mechanical properties of the coherent interface in materials of all scales. The effect of the residual strain caused by self-relaxation and the lattice misfit of nanomaterials, as well as that due to the interface deformation induced by an external load on the interface free energy density is considered. In contrast to the existing theories, the stress discontinuity at the interface is characterized by the interface free energy density through an interface-induced traction. As a result, the interface elastic constant introduced in previous theories, which is not easy to determine precisely, is avoided in the present theory. Only the surface energy density of the bulk materials forming the interface, the relaxation parameter induced by surface relaxation, and the mismatch parameter for forming a coherent interface between the two surfaces are involved. All the related parameters are far easier to determine than the interface elastic constants. The effective bulk and shear moduli of a nanoparticle-reinforced nanocomposite are predicted using the proposed theory. Closed-form solutions are achieved, demonstrating the feasibility and convenience of the proposed model for predicting the interface effect in nanomaterials.

  12. Particles dispersion on fluid-liquid interfaces

    This paper is concerned with the dispersion of particles on the fluid-liquid interface. In a previous study we have shown that when small particles,e.g.,flour,pollen,glass beads,etc.,contact an air-liquid interface,they disperse rapidly as ifthey were in an explosion. The rapid dispersion is due to the fact that the capillary force pulls particles into the interface causing them to accelerate to a large velocity. In this paper we show that motion of particles normal to the interface is inertia dominated: they oscillate vertically about their equilibrium position before coming to rest under viscous drag. This vertical motion of a particle causes a radially-outward lateral (secondary) flow on the interface that causes nearby particles to move away. The dispersion on a liquid-liquid interface,which is the primary focus of this study,was relatively weaker than on an air-liquid interface,and occurred over a longer period of time. When falling through an upper liquid the particles have a slower velocity than when falling through air because the liquid has a greater viscosity. Another difference for the liquid-liquid interface is that the separation of particles begins in the upper liquid before the particles reach the interface. The rate of dispersion depended on the size of the particles,the densities of the particle and liquids,the viscosities of the liquids involved,and the contact angle. For small particles,partial pinning and hysteresis of the three-phase contact line on the surface of the particle during adsorption on liquid-liquid interfaces was also important. The frequency of oscillation of particles about their floating equilibrium increased with decreasing particle size on both air-water and liquid-liquid interfaces,and the time to reach equilibrium decreased with decreasing particle size. These results are in agreement with our analysis.

    A Internet constitui um dos grandes avanços da comunicação humana. Através dela, é possível o contato com uma infinidade de informações, veiculadas pelos mais diversos gêneros de texto. Por isso, sendo um dos meios de comunicação que mais se expandiu no mundo, a Internet se apresenta como uma ferramenta indispensável no ensino-aprendizagem da leitura e da escrita. Partindo desse pressuposto, o presente trabalho pretende apresentar os resultados de um estudo que tem por objetivo investigar, à luz dos pressupostos empreendidos por Soares (1998 e Dionísio (2005, qual o “lugar” da Internet no processo de ensino-aprendizagem da leitura e da escrita, bem como até que ponto ela interfere de forma positiva e/ou negativa nesse processo. Para tanto, foram aplicados questionários a professores e alunos do Ensino Médio. A partir da análise dos dados, pretende-se verificar como a sobrecarga de informações, bem como o uso inadequado da Internet podem trazer implicações para o desenvolvimento dessas atividades.
