2015-04-01

Full Text Available As micro e pequenas empresas assumem papel importante para as economias locais e regionais. Grande parte desses empreendimentos não consegue prosperar e se manter no mercado por mais de meia década, apresentando mortalidade precoce. Mediante a isto, o presente trabalho é caracterizado como uma survey descritiva, visto que se consideram, no mesmo, os principais passos para esclarecimento a respeito de sobrevivência das micro e pequenas empresas. Desta forma, o objetivo foi identificar os fatores causadores da mortalidade dessas empresas na região central do estado do Rio Grande do Sul. Para tanto, a pesquisa agregou uma amostra de 60 empreendimentos. Utilizou-se para a coleta dos dados um questionário estruturado, no qual se identificou onze principais fatores causadores da mortalidade das empresas. Concluiu-se que existe relação entre os fatores encontrados na pesquisa com resultados obtidos por outros autores em estudos anteriores.

Teatro Depressinha. 5 Pequenas Peças de Teatro.

Directory of Open Access Journals (Sweden)

Leonor Martins Coelho

2013-09-01

Full Text Available Artefacto plural e educativo, o último livro de recepção infantil de José Viale Moutinho vem porfiar a ideia de como o teatro pode e deve ser entendido como uma arte expressiva, descomplexada e eficaz, enquanto experiência formativa intensa. Com essa arte performativa, é, então, possível instruir, divertindo, o jovem receptor. Dirigido, sensivelmente, a um leitor de 5 aos 10 anos, o livro que veio a lume em 2012, reúne três linguagens distintas mas convergentes. Em primeiro lugar, o texto colocado no começo do livro, em jeito de prefácio, intitulado “De Élvio Camacho, encenador e ator”, apresenta-se como um “modo de instrução” para explorar os meios dramatúrgicos que as cinco pequenas peças de Viale Moutinho reclamam. Quanto aos textos para teatro propriamente ditos, estes recuperam ora o tema do menino traquinas (“O menino lá do fundo da sala” e “aquele menino que se porta tão mal”, ora o tópico do teatro-circo (“Dom Adivinhão”, ora o universo da literatura oral e tradicional, de que o autor é um acérrimo defensor (“O tesouro do cego” e “Um favorzinho”. Na verdade, o engenho do autor consiste em fazer cruzar nas suas “pequenas comédias” todas essas fantasias e discursos.

O Programa Inovativo da Pequena Empresa (PIPE da FAPESP como indutor do desenvolvimento de micro e pequenas empresas de base tecnológica

Victor Wolowski Kenski

2017-09-01

Full Text Available Resumo Este texto analisa a relevância do apoio ao desenvolvimento de micro e pequenas empresas de base tecnológica na forma de um “pacote” de recursos e capacidades estratégicos incorporados em um curto espaço de tempo, por meio do programa PIPE da FAPESP. A abordagem adotada foi a da Visão Baseada em Recursos (VBR dado o foco do estudo. Adotou-se a metodologia qualitativa com a aplicação da análise de conteúdo. Os dados foram levantados com base em entrevistas com um roteiro estruturado com perguntas abertas junto aos sócios/gestores de 10 empresas de base tecnológica divididas em dois grupos, um deles constituído por empresas beneficiadas pelo PIPE e o outro por aquelas que utilizaram recursos próprios. A intenção foi comparar a sua evolução. Os resultados do estudo indicaram que o apoio do PIPE foi decisivo para favorecer o desenvolvimento das empresas beneficiadas por ele. Um dos ganhos relevantes foi o encurtamento do tempo do caminho percorrido para a disponibilização dos recursos complementares, como decorrência da combinação produtiva dos recursos e capacidades pré-existentes nas empresas com aqueles obtidos por meio do programa. Uma constatação importante foi que, para as empresas terem crescido no mercado de base tecnológica, independentemente da ajuda do PIPE, foi decisivo possuírem inicialmente uma tecnologia diferenciada, os sócios/gestores terem uma visão clara dos seus mercados e voltados à criação de valor para os seus produtos e serviços. A limitação da pesquisa está na seleção de pequenas empresas de base tecnológica com produtos muito distintos dificultando comparações sobre sucessos.

Full Text Available As pequenas empresas prestadoras de serviço têm desempenhado cada vez mais um papel importantíssimo para o crescimento da economia brasileira. Tais empresas se deparam com novas situações de mercado como concorrência, excelência na qualidade, clientes exigentes e conhecedores, necessidade de abrangência no mercado, cultura e clima organizacional, fornecedores e outras tantas variáveis muitas vezes nem conhecidas por seus administradores. A abordagem da Gestão Estratégica apresenta a necessidade de entender as variáveis e fatores que compõem o micro e macro ambiente das pequenas empresas, o processo de planejamento e de ações estratégicas que conduzam os objetivos e metas contribuindo para o sucesso das empresas diante de um mercado competitivo. O objetivo deste artigo é realizar uma revisão bibliográfica em torno do conceito Gestão Estratégica, para identificar como as pequenas empresas prestadoras de serviços implementam ações para suportar a ação estratégica. O método de pesquisa foi uma análise bibliométrica, por meio de procedimentos de pesquisa quantitativos e qualitativos, com análise documental de publicações no período entre 2006 e 2012, buscando-se artigos que contivessem em seus títulos o termo “Gestão Estratégica” com base de dados da biblioteca eletrônica SciELO.

Full Text Available Resumo Este artigo objetivou analisar a contribuição da metodologia Peir para estudo de uma pequena cidade da Amazônia a partir da análise do modo de vida da população. Como procedimento metodológico procurou-se entender a relação entre aspectos de urbanização conectados à globalização e saúde da população dessa cidade. Foram obtidos dados em campo, os quais permitiram analisar a situação de saúde em dois setores urbanos. A metodologia Pressão-Estado-Impacto-Resposta (Peir, desenvolvida pelo Programa das Nações Unidas para o Meio Ambiente (Pnuma e adaptada pela Organização para a Cooperação e Desenvolvimento Econômico (OCDE, servirá de suporte para a compreensão dos impactos na saúde da população a partir do acesso a infraestruturas disponíveis, entre elas o abastecimento de água. O local de estudo é cidade de Ponta de Pedras, situada na Ilha do Marajó, estado do Pará, Brasil. Como resultado nota-se a necessidade de intervenções imediatas por parte do poder público para minimizar os impactos das condições de vulnerabilidade sobre as populações.

Fernando Oliveira Tavares

2015-06-01

Full Text Available RESUMO Neste artigo, o objetivo é conhecer e analisar as formas de financiamento e produtos mais utilizados pelas pequenas e médias empresas do distrito do Porto, em Portugal. Pretende-se ainda perceber a aceitabilidade e a propensão para utilização de formas de financiamento alternativas e compreender quais as dificuldades das empresas no acesso ao crédito. O método utilizado é quantitativo e exploratório, um inquérito foi enviado a 1.600 empresas do distrito do Porto, acerca das diferentes formas de financiamento das organizações. Os resultados permitem concluir que o crédito bancário é a principal fonte de financiamento das pequenas e médias empresas, seguindo-se o autofinanciamento. O financiamento pela emissão de ações e obrigações é residual. Os resultados apresentam três fatores preponderantes quando as empresas têm necessidade de financiar-se: o crescimento da empresa, o custo do empréstimo e os aspetos burocráticos. Apesar de tratar-se de um estudo exploratório, os três fatores encontrados são um contributo para o estudo sobre o financiamento de pequenas e médias empresas, merecendo atenção por parte de investidores, gestores e detentores de capital.

Mini tunelizador moldável: um avanço técnico no acesso vascular para hemodiálise Mini moldable tunneler: a technical improvement for hemodialysis access

Fabio Henrique Rossi

2011-12-01

Full Text Available CONTEXTO: A confecção de fístula para hemodiálise pode envolver a criação de túnel para a acomodação do enxerto - veia autóloga ou prótese sintética. O trajeto e a extensão dependem do local escolhido para a realização das anastomoses e posicionamento do trajeto do enxerto. Na atualidade, os tunelizadores utilizados são constituídos de estruturas cilíndricas metálicas rígidas, que tornam necessário o uso de múltiplos tamanhos e conformações. OBJETIVO: Testar a utilização de um único mini tunelizador universal metálico e moldável na cirurgia de confecção de fístula para hemodiálise. MÉTODOS: Trata-se de um estudo piloto. O tunelizador desenvolvido consiste de uma estrutura cilíndrica e modular composta de fio de aço inoxidável moldável interno, com manopla em extremidade proximal e dupla ponta cônica intercambiável em extremidade distal e bainha cilíndrica externa de polietileno. O tunelizador foi utilizado em dez cirurgias de confecção de fístulas para hemodiálise em membros superiores e inferiores, e o sucesso de sua aplicabilidade e a frequência de complicações precoces foram observados. RESULTADOS: Suas características de maleabilidade e conformibilidade permitiram a utilização do mesmo tunelizador nos diversos tipos de fístulas realizadas. A ponta cônica distal com duplo diâmetro, intercambiável, permitiu que o mesmo aparato fosse aplicado na utilização de veia autógena ou prótese sintética. Todas as cirurgias foram seguidas de sucesso e com baixos índices de complicações precoces. CONCLUSÃO: A versatilidade do mini tunelizador metálico maleável e moldável permitiu sua utilização em todas as fístulas realizadas, independentemente do sítio das anastomoses e o trajeto de acomodação escolhido, sem complicações e com excelente índice de perviedade. Os dados sugerem que o mini tunelizador metálico maleável moldável pode ser utilizado com segurança e vantagens nas

Full Text Available O objetivo geral deste estudo é demonstrar a importância do planejamento tributário para as micro e pequenas empresas (MPE no Brasil. Já os alvos específicos são: identificar as formas de tributação existentes que podem ser utilizadas pelas MPE e verificar qual é a mais viável. Para atingir os objetivos deste estudo, foi realizada pesquisa bibliográfica a partir de artigos e livros do acervo da Faculdade Anhanguera, da Universidade Católica Dom Bosco (UCDB e de acervos pessoais, bem como de artigos de periódicos e legislação disponíveis na internet e manuais de pesquisa no site do Serviço Brasileiro de Apoio às Micro e Pequenas Empresas (Sebrae. Dos resultados encontrados, verificou-se que as MPE possuem papel relevante para a economia e, por esse motivo, o governo, nas últimas décadas, tem proporcionado vários incentivos visando estimular a abertura de mais empresas desse porte, bem como evitar que muitas entrem em falência, tendo em vista que pesquisas realizadas, principalmente pelo Sebrae, demonstram que é alto o índice de MPE que entram em falência todos os anos. Nas últimas décadas, após os incentivos adotados, entre eles a criação do Simples, nova forma de tributação especial para as MPE, verificou-se uma redução no fechamento de empresas desse porte, porém, o índice continua elevado. Várias são as causas para a falência das MPE, e dentre elas se destaca a alta carga tributária. Dessa forma, torna-se imprescindível que os empresários invistam na realização do planejamento tributário, a fim de escolher a melhor forma de tributação para evitar a falência.

No Brasil, o Estado de São Paulo concentra mais da metade das empresas brasileiras de pequeno porte. Assim sendo, estudos sobre o sucesso ou o insucesso de micro e pequenas empresas têm sua relevância enaltecida. Este estudo busca apresentar uma análise quantitativa e qualitativa sobre os fatores associados à mortalidade precoce das micro e pequenas empresas. Para tanto, realizou-se uma pesquisa com os gestores de micro e pequenas empresas da cidade de São Paulo que encerraram suas atividades. Para análise quantitativa da amostra, que apresenta representatividade estatística, utilizou-se de técnicas de análise multivariada. Como principal resultado, pode-se destacar que os fatores associados à mortalidade são preponderantemente de natureza estratégica, o que contraria o senso comum que professa a insuficiência de recursos como principal motivador da falência das pequenas empresas. Tal resultado tem importância para orientar as políticas públicas, os empreendedores e as agências de fomento para a formulação de suas estratégias no sentido do desenvolvimento de competências administrativas para o sucesso das micro e pequenas empresas brasileiras.The economic vigor of many countries is due to the success of small businesses.

Full Text Available Este texto tem como propósito descrever os procedimentos operacionais para a elaboração de um relatório de sustentabilidade para pequenas e médias empresas, com base nas diretrizes do Global Reporting Initiative(GRI. O estudo foi desenvolvido em uma empresa prestadora de serviços localizada na cidade de Chapecó/SC. Trata-se de uma pesquisa descritiva e qualitativa, e cuja coleta de dados empíricos foi feita no primeiro semestre de 2014. Foi constatado que o grau de dificuldade para a elaboração de um relatório de sustentabilidade em uma pequena empresa é grande, haja vista não haver recursos humanos disponíveis para monitorar os indicadores. Para obter êxito, é necessário comunicar a equipe da importância e necessidade de acompanhar os indicadores de desempenho das áreas econômica, social e ambiental. Além disso, o estratégico da organização precisa estar diretamente envolvido, para que seja possível obter a legitimidade da ideia no contexto organizacional. Sugere-se criar um comitê de sustentabilidade, coordenado pelo diretor da empresa, a fim de que este promova o engajamento de todos os colaboradores para a criação de uma cultura sensibilizada com as práticas de sustentabilidade. O passo seguinte é a realização de treinamentos e monitoramento dos indicadores relevantes para a gestão. Em seguida, devem-se fazer os registros e tabulá-los em formato de relatório, para posterior comunicação a todas as partes interessadas. Como ferramenta, adotar planilhas Excel, que evidenciam os indicadores, sua métrica de mensuração e o desempenho atingido pela organização mês a mês. De posse dos dados, é possível elaborar o relatório de sustentabilidade e criar metas de melhoria contínua.

AS CRIANÇAS PEQUENAS SOB UMA BOA GUARDA. SMALL CHILDREN IN SAFE CUSTODY

Directory of Open Access Journals (Sweden)

Eric Plaisance

2012-11-01

Full Text Available As limitações profissionais e de tempo dos pais, as possibilidades institucionais e sociais na guarda e no cuidado das crianças pequenas levaram os sociólogos a redefinir as “idades” da pequena infância: 0-2 anos, a creche; 2-3 anos, o “jardin d’éveil”3; a partir dos três anos, a escola maternal, à qual devemos acrescentar a guarda em casa e, para as classes mais ricas, a empregada doméstica. A partir deentrevistas com pais, E. Plaisance mostra que os interessados ressaltam a liberdade de escolha (mesmo quando as ofertas são raras e reforçam o tom da evidência de que a solução tomada era a melhor para eles e para a criança. Mas as respostas mostram também que eles buscam se informar, segundo meios que favorecem o “boca a boca” e que dão lugar aos fenômenos do rumor. De fato, a “escolha” dos atores é determinada, mas como para se tranquilizar e assumir suaresponsabilidade, eles a descrevem voluntariamente como “livre”.Due to the constraints of parental work schedules, the institutional and social opportunities in minding and caring for young children have grown. This has led sociologists to redefine the 'ages' of early childhood. These are: 0-2, the crèche, 2-3, the kindergarten and from three years old on, play school. To this must be added home care with a child-minder for wealthier classes. Based on interviewswith parents, É. Plaisance shows that those involved put freedom of choice first (even when the choices are rare and the weight of evidence underlines that the solution arrived at was the best for them and their child. But the responses also show that they try to inform themselves by ways that favor word of mouth and giveroom for rumor and hearsay. The 'choice' of those involved is constrained, but as if to reassure themselves and to show that they are assuming their responsibility, they willingly describe it as 'free'.

O propósito deste trabalho foi estabelecer um método para a verticalização de molares inferiores inclinados para mesial, utilizando ancoragem em mini-parafusos colocados na região de linha oblíqüa externa da mandíbula. Foram selecionados três pacientes entre 40 a 48 anos (dois do gênero feminino, um do gênero masculino, com molares inferiores inclinados para mesial e distalmente posicionados às áreas edêntulas. Os pacientes foram tratados ortodonticamente durante um período de 6 a 12 meses, com técnica ortodôntica MD3. Mini-parafusos de titânio foram colocados bilateralmente com anestesia local. Uma incisão sobre a linha oblíqüa externa da mandíbula, medindo aproximadamente 1 cm foi realizada em cada lado, distalmente aos molares inclinados. Após descolamento muco-periosteal, mini-parafusos foram implantados e foram realizadas suturas deixando suas cabeças exteriorizadas. Uma semana após a remoção das suturas, cargas ortodônticas (entre 150 a 200 gramas/força foram aplicadas através de forças elásticas. Verificamos que alguma inflamação foi observada ao redor dos mini-parafusos, mas foi controlada com procedimentos de higienização. O procedimento cirúrgico é simples, podendo ser realizado pelo ortodontista; as formas dimensionais dos mini-parafusos são adequadas e estes são de fácil remoção após uso. Concluímos que o uso de mini-parafusos representa uma alternativa efetiva de ancoragem ortodôntica na verticalização de molares inferiores.Tooth movement frequently requires additional anchorage resources. Mini-screws have been used as a possible solution to this matter. The purpose of this study was to establish a method of mandibular molar uprighting, using mini-screw as anchorage, positioned on the mandibular external oblique line, behind and

Full Text Available A lagarta do cartucho do milho é uma das principais pragas do milho nas Américas, podendo ocorrer durante todos os estágios de crescimento da cultura, causando perdas de 15 a 37% na produção. Neste trabalho estudou-se a distribuição espacial dessa praga no campo, com a finalidade de desenvolver um sistema de amostragem para estimar sua densidade populacional. Na área cultivada com milho foram selecionados 3 campos experimentais de 40 m x 250 m cada, divididos em 100 parcelas cada. Foram contados o número de lagartas pequenas e grandes de S. frugiperda nas folhas e no cartucho das plantas, em 10 plantas ao acaso por parcela, num total de 1000 plantas por campo, em 5, 5 e 4 datas de amostragem, respectivamente. Lagartas menores que 1 cm eram consideradas pequenas e lagartas maiores que 1 cm, grandes. Foram estimados os parâmetros da lei de Taylor, sendo as estimativas dos parâmetros das regressões altamente significativas para todas as categorias larvais. O parâmetro b da lei de Taylor para lagarta pequena foi igual a 1,57, indicando que a forma de distribuição dessa categoria larval é agregada. Para lagartas grandes o parâmetro b foi igual a 0,79, o que conduz a um tipo de distribuição tendendo para aleatoriedade. Para o número total de lagartas os resultados são equivalentes aos obtidos para lagartas pequenas. Foi desenvolvido um plano de amostragem seqüencial com base nos parâmetros da lei de Taylor.

Full Text Available Uma das limitações à expansão do mercado de alimentos orgânicos no Brasil é a carência de estudos e tecnologias apropriadas a estes sistemas de produção. O mercado de mini-hortaliças no Brasil é crescente e de grande valor comercial. São produtos de elevado valor agregado, apresentam boa rentabilidade para pequenas escalas de produção e são menos suscetíveis a oscilações de preços do que as tradicionais. Na produção de repolhos orgânicos no Brasil, observa-se dificuldade em se obter um produto comercial com peso médio desejado pelo consumidor. O objetivo deste trabalho foi avaliar a eficiência agronômica e a rentabilidade econômica da produção de mini-repolhos por rebrota, em função de níveis de adubação nitrogenada residual. Esse trabalho foi desenvolvido na Unidade de Referência em Agroecologia do INCAPER, localizada no município de Domingos Martins-ES, a uma altitude de 950 m. O experimento foi disposto no delineamento blocos casualizados, com 4 repetições. Os tratamentos consistiram de adubações à base de composto com cinco níveis de N, com aporte de 0, 450, 600, 750 e 900 kg/ha de N-total. O número, peso médio, diâmetro médio, produção total e comercial de cabeças de repolho, tanto na produção primária quanto de mini-repolhos apresentaram uma elevação significativa com os níveis de nitrogênio. No maior nível de adubação nitrogenada, obtiveram-se rendimentos comerciais de 59.628 kg/ha de repolhos e de 30.575 kg/ha de mini-repolhos, proporcionando receitas líquidas de R$ 61.559,00 e R$ 141.815,90, respectivamente. Os mini-repolhos apresentaram pesos médios de 227g a 253g e diâmetros médios de 8,9cm a 10,2cm. A produção de mini-repolhos confirmou-se como alternativa de grande vantagem econômica, com gasto de mão-de-obra 34,0% e custo de produção 45,8% menores que a produção primária. A rentabilidade da produção de mini-repolhos foi 130% maior que a produção primária de

Full Text Available As microempresas e as pequenas empresas (MPEs brasileiras possuem alta representatividade na economia, principalmente no tocante à oferta de empregos. Trata-se de um grupo expressivo e que apresenta uma série de singularidades no que diz respeito à tributação. Em razão de serem pequenas, elas podem incorrer em custos econômicos superiores ao das maiores empresas. Nesse sentido, muitos países têm buscado criar mecanismos específicos de apoio às MPEs. Com o Simples Nacional, o Brasil concedeu uma série de benefícios fiscais e simplificações administrativas para as microempresas e as pequenas empresas. A arrecadação do Simples Nacional cresceu a taxas muito superiores a de todos os demais tributos, tendo sido três vezes maior do que a taxa real de crescimento de toda a arrecadação. O valor arrecadado por estabelecimento cresceu expressivamente durante a vigência do Simples Nacional, corroborando a evidência de que houve forte crescimento das empresas optantes pelo novo regime. O crescimento da arrecadação trouxe como contrapartida o incremento das renúncias fiscais, que cresceram a taxas ainda maiores do que o aumento da arrecadação.

Joel Vieira Baptista Junior

2013-12-01

Full Text Available Neste trabalho são discutidos os principais aspectos relacionados à geração de resíduos da construção civil, sob ponto de vista de sustentabilidade das edificações. Esse conceito exige, das novas construções, a adoção de projetos criativos e eficientes, com soluções adequadas para as diversas fases de vida da obra, incluindo a previsão do reaproveitamento e descarte de materiais ao fim de sua vida útil. Um dos problemas atuais da gestão de resíduos da construção civil é que a segregação dos materiais por classe, visando à sua posterior reciclagem ou descarte, só acontece na cidade do Rio de Janeiro em grandes obras com canteiros instalados, embora mais da metade da quantidade produzida seja proveniente de pequenas obras com resíduos descartados em caçambas de rua ou simplesmente lançados em vias públicas ou terrenos baldios. É sugerido um plano de gestão circular, especialmente voltado para os pequenos geradores, com obrigatoriedade de segregação dos materiais, instalação de pontos de recolhimento pelos bairros da cidade e implantação de centros de tratamento de resíduos da construção civil, operados por associações de catadores, com objetivo de produção de materiais reciclados. O sucesso da proposta depende da efetiva participação de todos os agentes envolvidos no processo, como o poder público, proprietários, empresas e demais profissionais da indústria da construção civil.

Full Text Available No Brasil, ainda não existe um método padrão, confiável, para a determinação da curva de retenção de água em todos os tipos de substratos existentes para o cultivo de hortaliças, principalmente para substratos à base de fibras longas e curtas, como é o caso do substrato de coco verde. Assim, neste trabalho, o objetivo foi obter a curva de retenção de água em substratos para o cultivo de hortaliças, utilizando-se um mini sensor Irrigas®. Foram utilizados os substratos de coco verde, sem compostagem, compostado durante 45; 90; 135 e 180 dias e o substrato Plantmax®, utilizado como controle. O delineamento experimental foi de blocos ao acaso no esquema fatorial 6 x 11 (substrato x tensão com três repetições. Para o substrato S0; S45; S90; S135 e S180 as médias obtidas foram porosidade total: 85%; espaço de aeração: 72%; água facilmente disponível: 4%; água disponível: 9%; água tamponante: 5% e, água remanescente: 4%. O espaço de aeração (72%, foi indicativo de que é conveniente melhorar a distribuição do tamanho de partículas desse substrato, de modo a reduzir o espaço de aeração e aumentar a capacidade de retenção de água. O aumento da tensão de água foi obtido de forma natural, pela evaporação da água das amostras. A utilização do sensor Irrigas® permitiu rapidez na obtenção dos resultados e possibilitou a medição da tensão da água, de maneira contínua e paralela, entre tensões de 0 e 11 kPa, simultaneamente, em três amostras de substrato. Estes resultados tornaram evidente a possibilidade de uso do mini sensor Irrigas® na determinação de curvas de retenção de água em substratos para hortaliças, gerando inclusive perspectivas para a realização de estudos futuros de comparação com outros métodos.In Brazil, no reliable standard method exists to determine the water retention curve in all available types of substrates for the cultivation of vegetables, mainly for substrates

Esta pesquisa investiga o impacto do sistema jurídico na aceitação das normas internacionais, objetivando verificar se o ambiente jurídico (Common Law e Code Law influencia a opinião das partes interessadas no processo contábil em relação à norma para Pequenas e Médias Empresas (PME. A utilização da norma para PMEs ressalta, ainda mais, a relevância dos resultados obtidos, pois ela irá afetar a rotina contábil da maioria das empresas existentes nos países que estão adotando ou pretendem adotar as normas internacionais e não apenas as grandes corporações de capital aberto. Os dados foram coletados das opiniões sobre 4 perguntas utilizadas pelo IASB no seu Discussion Paper de criação da norma para PMEs. Os respondentes foram classificados de acordo com o sistema jurídico dos seus países de origem e conforme a entidade ou classe que representavam. Os achados da pesquisa indicam que não existem diferenças significativas entre as respostas aos questionamentos do IASB com base no sistema jurídico de origem do respondente e nem diferenças significativas nas respostas levando em conta diferentes categorias de respondentes. A inferência que pode ser tirada desta pesquisa é que, mesmo em países com sistemas jurídicos distintos, as opiniões dos representantes da contabilidade se alinham, o que pode ser um indício de que uma convergência de fato e não apenas de direito pode ser obtida com a introdução de padrões internacionais para as PMEs, o que contraria grande parte da literatura sobre o assunto.

Full Text Available Una de las causas mas importantes de la flacidez y caída de la piel y de las partes blandas de la cara es la disminución del volumen de su estructura esquelética. Un factor fundamental en la restauración del envejecimiento facial seria el poder recuperar este volumen. Dado que en la actualidad no se cuenta con un recurso efectivo para recuperar el volumen óseo, lo indicado es restaurar la relación entre las partes blandas y el volumen óseo vigente. Esta es la meta mas importante de la ritidectomía subperióstica. Con una vasta experiencia en este método y buscando minimizar las cicatrices resultantes, hemos desarrollado el enfoque mini-invasivo de este procedimiento de restauración facial. En el presente trabajo describimos la aplicación de nuestro procedimiento para la restauración de la región frontal. Desde 1998 hemos realizado este procedimiento, con diversas combinaciones y variantes y dependiendo de las necesidades de cada caso, en un total de 521 pacientes: 419 mujeres y 102 hombres de edades comprendidas entre los 45 y los 73 años. Planteamos las metas y describimos los medios para realizar este procedimiento por vía frontal, transpalpebral y combinando ambas vías, a la vez que damos orientación para lograr los objetivos del procedimiento y evitar complicaciones basándonos en la Anatomía Quirúrgica. Referimos los procedimientos auxiliares que se pueden asociar a este método y describimos los detalles del manejo postoperatorio. Los resultados obtenidos han sido en general muy satisfactorios tanto para los pacientes como para el cirujano. Mencionamos también las complicaciones observadas. En conclusión, describimos las observaciones resultantes de nuestra experiencia con este método a lo largo de 10 años, con resultados tan buenos o mejores que con la ritidectomía subperióstica abierta y el porqué es actualmente nuestro procedimiento de elección.The reduction of the bony structure of the face is the main reason

Full Text Available O artigo analisa sistematicamente uma pequena propriedade rural, chamada São Julião, que cria gado leiteiro no município de Campos dos Goytacazes, situado no norte fluminense do estado do Rio de Janeiro. Para tanto, fez-se uma análise Custo/Volume/Lucro (CVL nesta fazenda. Buscaram-se os dados in loco para calcular os parâmetros da ferramenta CVL, como os custos fixos, os custos variáveis, a margem de contribuição unitária e o ponto de equilíbrio. O estudo de caso mostrou aos donos do negócio que o ponto de equilíbrio da propriedade está muito próximo da venda mensal de 5000 L de leite, fazendo com que a margem de contribuição seja de R$0,17/L de leite e a margem de segurança seja apenas 18%, consideradas baixas para a atividade. A demonstração do resultado do exercício – DRE do mês de abril de 2011 confirmou, pelo método do custeio variável, o pouco retorno obtido no mês, R$142,82. Por fim, o uso da ferramenta Custo/Volume/Lucro permitiu que os proprietários analisassem o modo que estavam administrando e tomando as decisões em sua propriedade.

Full Text Available O diagnóstico diferencial entre a variante pequenas células do carcinoma epidermoide e do carcinoma de pequenas células nem sempre é fácil. Apesar de os descritores alertarem que o primeiro deva manter suas características morfológicas e, muitas vezes, diferenciação escamosa focal, a escassez de material aliada a artefatos de fixação frequentes nessas biópsias podem dificultar a vida do patologista. Entretanto, a definição entre um e outro pode alterar significativamente a escolha da modalidade terapêutica do paciente e, em alguns casos, influenciar seu prognóstico. Procuramos nesta publicação alertar para o problema e facilitar essa diferenciação, sugerindo um painel imuno-histoquímico.The differential diagnosis between small cell variant of squamous carcinoma and small cell carcinoma is not always simple. Despite the fact that studies show the former keeps its morphologic characteristics and focal squamous differentiation, the scarcity of the material as well as frequent fixation artifacts in these biopsies may hinder analysis. However, this differentiation between them may change significantly the choice of therapeutic approach and, in some cases, influence prognosis. In this paper, we draw attention to this problem and suggest a immunohistochemical panel to facilitate this differential diagnosis.

Dentre os atributos de qualidade sensorial exigidos para mini-cenouras, a cor externa é um dos mais importantes. Este trabalho objetivou comparar dois métodos de avaliação da cor em mini-cenouras: instrumental (colorimetria e sensorial (análise descritiva. Raízes de cenouras da variedade Indiana-F1 foram processadas na Indústria Mr. Rabbit Farm Ltda., divididas em dois lotes, onde um seguiu o fl uxograma de processamento da indústria e ao outro foi acrescentada a etapa de revestimento em solução polipeptídica a 2%. Os dois lotes foram armazenados em expositores verticais, sob duas temperaturas distintas, 5oC e 10oC, para posterior avaliação instrumental e sensorial da cor. A avaliação instrumental foi realizada com um colorímetro modelo Color Quest II (Sphere (“Hunter Lab Reston”, VA calibrado para cor branca. O método sensorial foi realizado por uma equipe composta por nove provadores adequadamente selecionados e treinados, utilizando escala não estruturada de 9 cm. Os resultados obtidos da análise instrumental indicaram não haver diferença signifi cativa (p>0,05 entre as mini-cenouras com e sem revestimento, armazenadas a 5 e 10º C. Já nos resultados da equipe treinada foi verifi cada diferença entre as amostras ( <0,05. Após 25 dias, as mini-cenouras revestidas foram classifi cadas, pela equipe treinada, com nenhum esbranquiçamento e as não revestidas como muito esbranquiçadas, demonstrando que o método sensorial foi mais efi ciente para avaliação do esbranquiçamento de mini-cenouras.

The BaBar Mini

International Nuclear Information System (INIS)

Brown, David N.

2003-01-01

BaBar has recently deployed a new event data format referred to as the Mini. The mini uses efficient packing and aggressive noise suppression to represent the average reconstructed BaBar event in under 7 KBytes. The Mini packs detector information into simple transient data objects, which are then aggregated into roughly 10 composite persistent objects per event. The Mini currently uses Objectivity persistence, and it is being ported to use Root persistence. The Mini contains enough information to support detailed detector studies, while remaining small and fast enough to be used directly in physics analysis. Mini output is customizable, allowing users to both truncate unnecessary content or add content, depending on their needs. The Mini has now replaced three older formats as the primary output of BaBar event reconstruction. A reduced form of the Mini will soon replace the physics analysis format as well, giving BaBar a single, flexible event data format covering all its needs

Representando 85 % da estrutura fundiária paranaense, as pequenas propriedades buscam erradicar a espécie pelos prejuízos decorrentes. Os mecanismos propostos para manejo silvicultural dos remanescentes baseiam-se em dois pontos
centrais - alteração dos normativos legais vigentes por serem  impeditivos ao plantio, aliado ao incremento do fomento para plantio, especialmente nas áreas de Reserva Legal. Nesse sentido, dentre as experiências conduzidas pela EMATER, para estímulo ao manejo do pinheiro, destacam-se as unidades metodológicas para difusão de
tecnologia, a premiação de produtores de destaque municipal, a utilização de mecanismos de apoio para novos plantios, a formação de grupos de produtores para coleta, padronização e comercialização do pinhão em parceria industrial.

Full Text Available OBJETIVOS: Descrever as condições de trabalho em micro e pequenas empresas do setor de alimentos e bebidas e avaliar a saúde e a capacidade para o trabalho dos trabalhadores selecionados. MÉTODOS: Foram analisados dados previdenciários e registros de exames médicos periódicos. Para as observações das condições de trabalho, utilizou-se uma ficha criada especificamente para aplicar o Diagnóstico Ergonômico Curto e, para o inquérito, o Índice de Capacidade para o Trabalho (ICT e o Perfil de Saúde de Nottingham (PSN. RESULTADOS: Os seguintes fatores de risco e situações geradoras de desconforto foram observados: transporte manual de cargas; trabalho em pé e em série; bancadas improvisadas; instalações perigosas e ferramentas em mau estado de conservação. A maioria dos trabalhadores eram homens, com idade aproximada de 32 anos. O escore médio encontrado para o ICT foi de 43 (DP=4,25, indicando boa capacidade para o trabalho. As doenças musculoesqueléticas foram as mais diagnosticadas e os sintomas mais autorrelatados. Segundo o PSN, o estado geral de saúde dos trabalhadores pode ser considerado bom. CONCLUSÕES: Apesar da relevância das empresas de pequena dimensão na economia nacional, a base familiar e o reduzido capital explicam os baixos investimentos na estrutura física e nos processos produtivos. Ainda, a falta de conhecimento sobre segurança e saúde no trabalho gera situações de risco para o empregado. Vislumbram-se resultados positivos, que poderão ser documentados por meio de monitoramento longitudinal, após esta experiência que aliou investigação, formação e intervenção para apoiar essas empresas, geralmente excluídas de ações sociais mais amplas.OBJECTIVES: To describe working conditions in small companies in the food and beverage sector and to assess the health and the work ability of the selected workers.

Full Text Available Este estudo, sustentado nas premissas teoricas do modelo de gestão por competencias, objetiva explorar, descrever e mudar a sistematica de execução das atividades de uma pequena empresa de consultoria. Orientando-se por autores que propoem a operacionalização do conceito de competencias nas organizacões, construiram-se quadros de referencias para as celulas da organização de modo que houvesse mais transparencia e consistencia nas ações de gestão, e isso representa um grave problema das pequenas empresas. Os quadros são compostos de atributos como missão, atribuições, contribuições, indicadores de resultados e competencias, todos definidos com base nas estrategias e nos objetivos almejados pela organização. Ante a proposta de não apenas explorar e descrever, mas tambem de mudar, o estudo utilizou como orientação metodologica a pesquisa-ação. Esse metodo não se limita apenas a descrever uma situação, mas tambem pretende desencadear, em certos casos, mudancas no seio da coletividade envolvida. O proprio processo de busca e os resultados alcancados demonstraram, a principio, que a estruturação de uma empresa por competencias gera turbulencias iniciais, principalmente pela radicalidade da mudança (neste caso e pelas particularidades do conceito. A nova estrutura tem provocado mudanças culturais, sobretudo na açao dos gestores que tem agora informações claras sobre as atribuições e exigencias cabiveis a cada celula, bem como de seus respectivos indicadores de desempenho.

Full Text Available Por meio de tecnologia adequada, foi possível desenvolver, com material polimérico à base de celulose e derivado do ácido poliacrílico, dispositivos de liberação sustentada do íon fluoreto para aplicação intrabucal. O princípio ativo usado foi o fluoreto de sódio, e os dispositivos foram preparados por compressão ou por revestimento de um núcleo, o que lhes promoveu bioadesividade e dimensões adequadas. Como produtos acabados, os dispositivos tiveram comportamento adequado com relação à sua finalidade, uma vez que liberavam continuamente pequenas quantidades do íon fluoreto. Com relação ao tempo de uso, foi conseguida liberação eficaz durante 8 horas. No tocante à aplicação medicamentosa, esses dispositivos oferecem uma soma de vantagens, sendo a principal delas o fornecimento do agente terapêutico no local correto (no alvo e a sua manutenção constante nesse local em pequena concentração, mas com plena atividade. O desenvolvimento desses dispositivos abre um campo para novas terapias.

Full Text Available Este estudo tem como objetivo analisar o processo de internacionalização de pequenas empresas (MPEs brasileiras da indústria de software e adota como base teórica modelo que sintetiza as perspectivas da aprendizagem experiencial, do planejamento sistemático e da abordagem contingencial na internacionalização de empresas. A base empírica do trabalho é formada por uma amostra de empresas do setor de software do Estado do Rio Grande do Sul (Brasil. Realizou-se, em uma primeira etapa, um levantamento de dados com uma amostra de 29 empresas com atuação internacional. Desta amostra foram selecionados cinco casos para uma análise qualitativa em uma abordagem de estudo de casos múltiplos. Os resultados indicaram que a internacionalização de MPEs não é consequência de um planejamento e, sim, de oportunidades percebidas pelos empresários em seus relacionamentos. Além disso, o estudo revela que capacidades organizacionais constituem-se em fator chave nesse processo e que a falta de conhecimento sobre o mercado externo é o principal obstáculo para a internacionalização das empresas de software investigadas.

Full Text Available Analisa-se o comportamento atual e futuro dos mercados institucional e não institucional de produtos da pequena produção, desenvolvida em projetos de assentamento da reforma agrária da região da Transamazônica e da BR-163 no estado do Pará. Apresentam-se os subsistemas de uso da terra na Amazônia, as características dos sistemas de produção e as formas de inserção no mercado, evidenciando os fatores que limitam a expansão da agricultura familiar e as oportunidades para seguir uma trajetória de uma agricultura de baixo carbono no contexto do desenvolvimento regional. Os resultados mostram que a continuidade do sistema de produção atual tende para uma especialização da agricultura familiar em apenas quatro cadeias produtivas: cacau, mandioca, madeira e pecuária. Por outro lado, há excedente de oferta para um conjunto de produtos, que dever ser exportado para outros mercados nacionais e internacionais e um excesso de demanda para uma cesta de produtos da agricultura familiar, cujo equilíbrio pode ser conseguido com o ajuste e efetivação da atual política de apoio à agricultura familiar.

A metodologia da pesquisa é qualitativa, tendo sido realizadas entrevistas com roteiros semiestruturados com empresários. Como resultados, pode-se depreender das análises que, mesmo não dominando conceitos e ferramentas de marketing, os empresários possuem orientação de mercado no que se refere à gestão de sua empresa. Os resultados confirmam que, ainda que o conceito de marketing seja desconhecido por muitos empresários, os mesmos o implementam sem ter consciência de que o estão fazendo, conseguindo se manterem no mercado por meio de ações informais que investem no relacionamento com o consumidor.

Reconhecendo as debilidades estruturais das empresas de pequeno porte e as dificuldades para a realização de investimentos ambientais, defende o uso de incubadoras como instrumento de política pública para estimular investimentos ambientais. Identifica um número restrito de incubadoras de tecnologias ambientais, em plano internacional. Relata os resultados de uma pesquisa que avaliou a aplicabilidade de um indicador para apurar o desempenho ambiental de incubadoras. Destacaram-se dois resultados: a a baixa importância atribuída, pelas incubadoras (e pelas empresas abrigadas ao desempenho ambiental; e b a ausência de estímulos, pelas incubadoras, aos investimentos ambientais. Desse último resultado deriva importante conclusão: a de que, uma vez apurados os padrões insatisfatórios de desempenho ambiental, de incubadoras e empresas assistidas, ficariam criadas as condições para a formulação e a implementação de medidas indutoras de novas posturas.The paper aims to contribute to academic reflections on the role of business incubators as institutional agents to promote environmental performance by small firms. Based on the assumption that these firms have natural structural weaknesses and, as a consequence, intrinsic difficulties in investing in environmental assets, the paper suggests that a particular public policy, namely, business incubators, could contribute to overcoming these barriers and thus pave the way for environmental investments. Two important findings should be highlighted: a the neglect of the incubators investigated (and thus, of the nurtured firms with respect to environmental performance; b the absence of stimuli, from business incubators, for environmental investments. From the results, an important conclusion may be drawn: namely, that where weak patterns of environmental

There is a need for psychiatric assessment instruments that enable reliable diagnoses in persons with hearing loss who have sign language as their primary language. The objective of this study was to assess the validity of the Norwegian Sign Language (NSL) version of the Mini International Neuropsychiatric Interview (MINI). The MINI was translated into NSL. Forty-one signing patients consecutively referred to two specialised psychiatric units were assessed with a diagnostic interview by clinical experts and with the MINI. Inter-rater reliability was assessed with Cohen's kappa and "observed agreement". There was 65% agreement between MINI diagnoses and clinical expert diagnoses. Kappa values indicated fair to moderate agreement, and observed agreement was above 76% for all diagnoses. The MINI diagnosed more co-morbid conditions than did the clinical expert interview (mean diagnoses: 1.9 versus 1.2). Kappa values indicated moderate to substantial agreement, and "observed agreement" was above 88%. The NSL version performs similarly to other MINI versions and demonstrates adequate reliability and validity as a diagnostic instrument for assessing mental disorders in persons who have sign language as their primary and preferred language.

Full Text Available OBJECTIVE: Mini-Mental State Examination cutoffs have been presented for schooling levels to screen cognitive impairment. However, items may behave differently with regards to education. The objective of this study was to examine the impact of education on MMSE subscales and items. METHOD: Community-dwelling participants aged 65 years or more (n = 990, females = 637, age = 74.1 years, range 65-108 were stratified as illiterate (n = 373, 1-8 (n = 540, 9-12 (n = 63, and more than 12 years of schooling (n = 14 and were screened with MMSE and Pfeffer Functional Activities Questionnaire. To make the Mini-Mental State Examination items comparable, each item was transformed into z scores. Multiple linear regression was used to estimate the effect of schooling on MMSE subs and items controlling for age, sex, and activities of daily life. RESULTS: Temporal and space orientation, attention/calculation, repetition, reading, writing, and drawing scores improved as education increased, but not memory registration, three step command, and naming. Reading and writing displayed the largest coefficients, whereas education exerted no influence on naming and three step command tasks. CONCLUSION: Education does not exert an important effect on naming, three step command, memory registration, and delayed recall. As memory is a key factor for diagnosing dementia, these items could be considered despite education.OBJETIVO: Vários pontos de corte foram propostos para o Mini Exame do Estado Mental para rastrear cognição.

MiniCNT - A Tabletop Stellarator

Science.gov (United States)

Dugan, Chris; Pedersen, Thomas; Berkery, John

2006-10-01

MiniCNT is a scaled down version of the Columbia Non-Neutral Torus, a stellarator built to study confinement of non-neutral plasmas on magnetic surfaces. MiniCNT is a glass vacuum chamber capable of holding pressures six orders of magnitude below atmospheric pressure. Unlike CNT, in which plasmas are invisible, MiniCNT allows some collisions with neutrals, causing it to glow. Using two twelve-volt car batteries to power four magnetic coils, MiniCNT generates a 0.02 Tesla magnetic field. While CNT, being larger, is obviously more accurate, there are multiple benefits in MiniCNT. First, it is more flexible and can be adjusted to fit many scenarios easily. The car batteries can be switched for other power sources, the coils can be realigned, and the chamber can be pumped to various pressures of various gases. Also, it is visually accessible; while CNT has glass viewing ports and its plasma is dark, MiniCNT is made of glass and its plasma glows, allowing visualization of the magnetic surfaces.

We aimed to compare the Mini-Mental State Examination (MMSE) with the Mini-Cog, measuring agreement in participants' classification, using a general population sample. Cross-sectional evaluation of 609 community dwellers aged ≥60 years was performed by trained interviewers. Cohen's kappa and 95% confidence intervals (CI) were calculated to assess overall agreement, and Cronbach alphas computed to assess reliability. Two-parameter Item Response Theory models (difficulty and discrimination parameters) were used to assess discrimination. Considering MMSE cut-point for scores Mini-Cog's cut-point score Mini-Cog Mini-Cog Mini-Cog's alpha was 0.2776. Co-calibration according to inherent ability is graphically presented. Agreement between scales seems fragile in our sample. The discriminative and reliability analysis suggests a better performance for subsets of the MMSE compared with the Mini-Cog. Usefulness of calibrated scores is discussed. Copyright © 2012 S. Karger AG, Basel.

The Mini-grid Policy Tool-kit is for policy makers to navigate the mini-grid policy design process. It contains information on mini-grid operator models, the economics of mini-grids, and necessary policy and regulation that must be considered for successful implementation. The publication specifically focuses on Africa. Progress on extending the electricity grid in many countries has remained slow because of high costs of gird-extension and limited utility/state budgets for electrification. Mini-grids provide an affordable and cost-effective option to extend needed electricity services. Putting in place the right policy for min-grid deployment requires considerable effort but can yield significant improvement in electricity access rates as examples from Kenya, Senegal and Tanzania illustrate. The tool-kit is available in English, French and Portuguese

Full Text Available Com base no exame da literatura pertinente, este trabalho busca ampliar o debate sobre o conceito de pequena empresa e identifica as formas de sua inserção na estrutura industrial. Ficou evidenciada a conceituação da pequena empresa como "pequeno capital", cuja posição e desempenho estão estreitamente vinculados ao processo de oligopolização. Nessa direção, procurou-se deixar clara a existência de quatro possíveis trajetórias de inserção para o segmento: disputa de espaço em mercados ainda pouco oligopolizados e com acentuada concorrência em preços; exploração de novos "nichos" de mercado; organização "em rede", com predominância de pequenas empresas e sem liderança explícita de grandes empresas; e inserção em redes de subcontratação comandadas por grandes empresas. Frente a esse conjunto de trajetórias, fica evidente que é inadequado o tratamento das pequenas empresas como um bloco homogêneo (ou como uma "questão geral", seja no que se refere às condições que explicam sua sobrevivência e seu crescimento, seja no âmbito das medidas de política econômica voltadas à sua promoção. O importante passa a ser não o porte, mas antes o potencial de contribuição para a obtenção dos resultados planejados ao se definir medidas de apoio, entre elas a preservação e aumento do emprego.Based on the analysis of the relevant literature, this study amplifies the debate about the concept of small business and identifies the possible space for it in the industrial structure. The concept of small business has been evidenced as "small capital", whose position and performance are closely linked to the process of oligopolization. Along these lines, four possible insertion trajectories for the segment have been sought to be highlighted: struggle for space in markets still not so oligopolized and with emphasized price competition; exploration of new market niches; network organization, with predominance of small business

This article describes medical students’ experience of mini-clinical evaluation exercise (mini-CEX during their clerkship in consultation psychiatry. Materials and methods: In our center during inpatient consultation psychiatry clerkship, all rotating students are expected to complete one mini-CEX assessment as part of their clinical training. We conducted retrospective analysis of mini-CEX ratings completed from 2013 to 2016. All evaluations took place at inpatient medical setting in patients admitted with medical conditions and psychiatric comorbidities. Results: A total of 113 evaluations were reviewed. The time examiner observed the interaction of a student with the patient was 14.24 minutes (mean, and the time spent in providing feedback to the student was 9.71 minutes. Complexity of problem was rated as low in 0.88% (n=1, moderate in 50.44% (n=57, and high in 48.67% (n=55. Highest ratings were for professionalism, similar to previous reports. Total score calculated by examiner showed no difference by the complexity of the patient; however, we observed a trend in higher counseling score for the high complexity group. Conclusion: Mini-CEX assessment during busy clerkship is feasible with good outcomes. Direct observation of medical trainees with actual patients is important for the assessment of performance-based clinical skills. Hospital psychiatry rotation

In base of the dynamic behavior of the GIAE a scheme of simple control is proposed to regulate the generator voltage with the minimum of necessary elements, which is translated into a reduced cost, greater reliability and in addition provides a satisfactory voltage regulation. The control strategy is simple but functional, which permits its implementation without major complications. Finally an analysis is realized of the harmonic distortion produced by the proposed control.

Full Text Available RESUMO: O presente trabalho avalia algumas metodologias utilizadas na determinação do módulo de deformação cisalhante para a previsão do comportamento dinâmico de fundações superficiais de aerogeradores assentes em solos arenosos. Para avaliar o comportamento dinâmico das fundações de máquinas, deve-se estimar a frequência de vibração do sistema solo-fundação que é calculada em função dos parâmetros dinâmicos do solo. Tal frequência é obtida a partir do módulo de deformação cisalhante (G, que, por sua vez, é função do nível de deformação do solo. Por simplificações, esse parâmetro é normalmente estimado através de ensaios estáticos, com grandes deformações, estando sujeito a imprecisões. No presente trabalho, calcularam-se os parâmetros dinâmicos do solo do campo experimental de fundações da Universidade Estadual de São Paulo (UNESP, em Bauru, a partir dos resultados de ensaios anteriormente realizados no local por VITALI (2011. Foi considerado um aerogerador com características idênticas ao aerogerador avaliado por Moura (2007 inserido no solo em análise. Assim, determinaram-se as frequências de vibrações da fundação de tal aerogerador. Tais frequências foram determinadas a partir de estimativas G por meio de ensaios estáticos e dinâmicos. Concluiu-se que as variações obtidas para o módulo cisalhante, com grandes e pequenas deformações, causaram um erro percentual cerca de 40% nas frequências e cerca de 60% nas amplitudes de vibrações. Destacam-se, com tal resultado, as variações das respostas dinâmicas quando são estimados por ensaios de grande e pequena deformação, reafirmando a importância de ensaios de pequena deformação para estimativas de respostas a carregamentos dinâmicos.

The goals of the study were to examine test-retest reliability, informant agreement and convergent and discriminant validity of nine DSM-IV-TR psychiatric disorders classified by parent and youth versions of the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID). Using samples drawn from the general population and child mental health outpatient clinics, 283 youth aged 9 to 18 years and their parents separately completed the MINI-KID with trained lay interviewers on two occasions 7 to 14 days apart. Test-retest reliability estimates based on kappa (κ) went from 0.33 to 0.79 across disorders, samples and informants. Parent-youth agreement on disorders was low (average κ = 0.20). Confirmatory factor analysis provided evidence supporting convergent and discriminant validity. The MINI-KID disorder classifications yielded estimates of test-retest reliability and validity comparable to other standardized diagnostic interviews in both general population and clinic samples. These findings, in addition to the brevity and low administration cost, make the MINI-KID a good candidate for use in epidemiological research and clinical practice.

[Bone remodeling and modeling/mini-modeling.

Hasegawa, Tomoka; Amizuka, Norio

Modeling, adapting structures to loading by changing bone size and shapes, often takes place in bone of the fetal and developmental stages, while bone remodeling-replacement of old bone into new bone-is predominant in the adult stage. Modeling can be divided into macro-modeling(macroscopic modeling)and mini-modeling(microscopic modeling). In the cellular process of mini-modeling, unlike bone remodeling, bone lining cells, i.e., resting flattened osteoblasts covering bone surfaces will become active form of osteoblasts, and then, deposit new bone onto the old bone without mediating osteoclastic bone resorption. Among the drugs for osteoporotic treatment, eldecalcitol(a vitamin D3 analog)and teriparatide(human PTH[1-34])could show mini-modeling based bone formation. Histologically, mature, active form of osteoblasts are localized on the new bone induced by mini-modeling, however, only a few cell layer of preosteoblasts are formed over the newly-formed bone, and accordingly, few osteoclasts are present in the region of mini-modeling. In this review, histological characteristics of bone remodeling and modeling including mini-modeling will be introduced.

Small portions of the barcode region - mini-barcodes - may be used in place of full-length barcodes to overcome DNA degradation for samples with poor DNA preservation. 591,491,286 rbcL mini-barcode primer combinations were electronically evaluated for PCR universality, and two novel highly universal sets of priming sites were identified. Novel and published rbcL mini-barcode primers were evaluated for PCR amplification [determined with a validated electronic simulation (n = 2765) and empirically (n = 188)], Sanger sequence quality [determined empirically (n = 188)], and taxonomic discrimination [determined empirically (n = 30,472)]. PCR amplification for all mini-barcodes, as estimated by validated electronic simulation, was successful for 90.2-99.8% of species. Overall Sanger sequence quality for mini-barcodes was very low - the best mini-barcode tested produced sequences of adequate quality (B20 ≥ 0.5) for 74.5% of samples. The majority of mini-barcodes provide correct identifications of families in excess of 70.1% of the time. Discriminatory power noticeably decreased at lower taxonomic levels. At the species level, the discriminatory power of the best mini-barcode was less than 38.2%. For samples believed to contain DNA from only one species, an investigator should attempt to sequence, in decreasing order of utility and probability of success, mini-barcodes F (rbcL1/rbcLB), D (F52/R193) and K (F517/R604). For samples believed to contain DNA from more than one species, an investigator should amplify and sequence mini-barcode D (F52/R193). © 2013 John Wiley & Sons Ltd.

Ducted mini-split heat pumps are gaining popularity in some regions of the country due to their energy-efficient specifications and their ability to be hidden from sight. Although product and install costs are typically higher than the ductless mini-split heat pumps, this technology is well worth the premium for some homeowners who do not like to see an indoor unit in their living area. Due to the interest in this technology by local utilities and homeowners, the Bonneville Power Administration (BPA) has funded the Pacific Northwest National Laboratory (PNNL) and the National Renewable Energy Laboratory (NREL) to develop capabilities within the Building Energy Optimization (BEopt) tool to model ducted mini-split heat pumps. After the fundamental capabilities were added, energy-use results could be compared to other technologies that were already in BEopt, such as zonal electric resistance heat, central air source heat pumps, and ductless mini-split heat pumps. Each of these technologies was then compared using five prototype configurations in three different BPA heating zones to determine how the ducted mini-split technology would perform under different scenarios. The result of this project was a set of EnergyPlus models representing the various prototype configurations in each climate zone. Overall, the ducted mini-split heat pumps saved about 33-60% compared to zonal electric resistance heat (with window AC systems modeled in the summer). The results also showed that the ducted mini-split systems used about 4% more energy than the ductless mini-split systems, which saved about 37-64% compared to electric zonal heat (depending on the prototype and climate).

Mini-implants: mechanical resource for molars uprighting

Directory of Open Access Journals (Sweden)

Susiane Allgayer

2013-02-01

Full Text Available INTRODUCTION: The early orthodontic treatment allows correction of skeletal discrepancies by growth control, and the elimination of deleterious habits, which are risk factors for the development of malocclusions, favoring for the correction of tooth positioning later in a second treatment stage. During development of teeth and occlusion, the mandibular second molars commonly erupt in the oral cavity after all other teeth of the anterior region. In their eruptive process there may be a condition known as tooth impaction, which precludes its complete eruption and requires proper uprighting treatment. The temporary anchorage devices allow disimpaction and movement of these teeth directly to their final position, without the need of patient compliance or reaction movements in other parts of the arch. OBJECTIVE: This paper aims at describing a case report of the treatment of a patient with Angle Class II malocclusion, performed in two phases, in which mini-implants were used for uprighting the impacted mandibular second molars.INTRODUÇÃO: o tratamento ortodôntico precoce permite a correção das discrepâncias esqueléticas por meio do controle de crescimento e a eliminação de hábitos deletérios, que são fatores de risco para o desenvolvimento de más oclusões, que favorecem a correção do posicionamento dentário mais tardiamente, em uma segunda fase do tratamento. Durante o desenvolvimento da dentição e da oclusão, normalmente o segundo molar inferior chega à cavidade bucal após todos os dentes posicionados anteriormente a ele. Durante seu processo eruptivo, pode ocorrer uma condição chamada "impacção dentária", em que sua erupção completa é interrompida, exigindo tratamento apropriado para verticalização. Os dispositivos temporários de ancoragem permitem a desimpacção e a movimentação desses dentes diretamente às suas posições finais, sem a necessidade de cooperação do paciente e sem movimento de reação nas

Full Text Available Este estudo trata dos modos de apresentação das culturas afro-brasileiras a bebês e crianças pequenas em escolas de educação infantil. O propósito da pesquisa foi investigar e analisar o trabalho pedagógico relacionado às culturas Afro-brasileiras que estão sendo realizados para implementar as Diretrizes Curriculares Nacionais para a Educação Infantil (DCNEI, de 2009. Segundo o Art 7º, inciso V, desse documento, as Propostas Pedagógicas devem estar comprometidas com o rompimento das relações de dominação diversas, inclusive, étnico-racial. A coleta de dados foi efetivada pelas estudantes do curso de Pedagogia do Complexo de Ensino Superior de Cachoeirinha, no primeiro semestre de 2015, em onze escolas de educação infantil, públicas e privadas, da grande Porto Alegre. Tal investigação foi organizada em dois momentos, sendo que no primeiro houve uma investigação empírica abarcando observações nas turmas de berçário e entrevistas semiestruturadas com as professoras e gestoras. Em um segundo momento as estudantes retornaram às escolas e desenvolveram práticas pedagógicas voltadas à cultura Afro-brasileira nas turmas pesquisadas. Os resultados da pesquisa mostraram que a maioria das escolas não contempla essa temática racial em seus projetos pedagógicos e, além disso, as gestoras e professoras conhecem muito vagamente as DCNEI. Com relação ao espaço e aos materiais foi constatado que, praticamente, não há imagens de pessoas negras nas paredes das escolas e, em algumas delas, nenhuma boneca negra no acervo de brinquedo disponível para as crianças brincarem. As professoras e gestoras entrevistadas afirmaram que não ocorrem problemas raciais na educação infantil e justificaram que as crianças de 0-3 são pequenas e não percebem tais diferenças. Esse discurso evidencia uma concepção superada de infância a qual desconsidera a potência dos bebês e suas possibilidades de interagir e aprender o mundo

Since over forty years structuralized interviews for clinical and epidemiological research in child and adolescent psychiatry are being developed that should increase validity and reliability of diagnoses according to classification systems (DSM and ICD). The aim of the study is to assess the validity of the Polish version of MINI-KID (Mini International Neuropsychiatric Interview for Children and Adolescents) in comparison to clinical diagnosis made by a specialist in the field of child and adolescent psychiatry. There were 140 patients included in the study (93 boys, 66.4%, mean age 11.8±3.0 and 47 girls 33.5%, mean age 14.0±2.9). All the patients were diagnosed by the specialist in the field of child and adolescent psychiatry according to ICD-10 criteria and by the independent interviewer with the Polish version of MINI-KID (version 2.0, 2001). There was higher agreement between clinical diagnoses and diagnoses based on MINI-KID interview with respect to eating disorders and externalizing disorders (κ 0.43-0.56) and lower in internalizing disorders (κ 0.13-0.45). In the clinical interview, there was smaller number of diagnostic categories (maximum 3 diagnoses per one patient) in comparison to MINI-KID (maximum 10 diagnoses per one patient), and the smaller percentage of patients with one diagnosis (65,7%) in comparison to MINI-KID interview (72%). Our study has shown satisfactory validity parameters of MINI-KID questionnaire, promoting its use for clinical and epidemiological settings. The Mini International Neuropsychiatry Interview for Children and Adolescent (MINI-KID) is the first structuralized diagnostic interview for assessing mental status in children and adolescents, which has been translated into Polish language. Our validation study demonstrated satisfactory psychometric properties of the questionnaire, enabling its use in clinical practice and in research projects. Copyright © 2014 Elsevier Inc.

1974-01-01

The original Mini-Sniffer on Rogers Dry Lake, adjacent to NASA's Flight Research Center, Edwards AFB. This version of the remotely-piloted vehicle had swept-back wings, tip rudders, nose canards, and an air breathing engine. The Mini-Sniffer was a remotely controlled, propeller-driven vehicle developed at the NASA Flight Research Center (which became the Dryden Flight Research Center, Edwards, California, in 1976) as a potential platform to sample the upper atmosphere for pollution. The vehicle, flown from 1975 to 1977, was one of the earliest attempts by NASA to develop an aircraft that could sense turbulence and measure natural and human-produced atmospheric pollutants at altitudes above 80,000 feet with a variable-load propeller that was never flight-tested. Three Mini-Sniffer vehicles were built. The number 1 Mini-Sniffer vehicle had swept wings with a span of 18 feet and canards on the nose. It flew 12 flights with the gas-powered engine at low altitudes of around 2,500 feet. The number 1 vehicle was then modified into version number 2 by removing the canards and wing rudders and adding wing tips and tail booms. Twenty flights were made with this version, up to altitudes of 20,000 feet. The number 3 vehicle had a longer fuselage, was lighter in weight, and was powered by the non-air-breathing hydrazine engine designed by NASA's Johnson Space Center in Houston, Texas. This version was designed to fly a 25-pound payload to an altitude of 70,000 feet for one hour or to climb to 90,000 feet and glide back. The number 3 Mini-Sniffer made one flight to 20,000 feet and was not flown again because of a hydrazine leak problem. All three versions used a pusher propeller to free the nose area for an atmospheric-sampling payload. At various times the Mini-Sniffer has been considered for exploration in the carbon dioxide atmosphere of the planet Mars, where the gravity (38 percent of that on Earth) would reduce the horsepower needed for flight.

Full Text Available Temporary anchorage devices popularly called mini-implants or miniscrews are the latest addition to an orthodontist′s armamentarium. The following case report describes the treatment of a 16-year-old girl with a pleasant profile, moderate crowding and Angle′s Class II molar relationship. Maxillary molar distalization was planned and mini-implants were used to preserve the anterior anchorage. After 13 months of treatment, Class I molar and canine relation was achieved bilaterally and there was no anterior proclination. Thus, mini-implants provide a viable option to the clinician to carry out difficult tooth movements without any side effects.

Roberto Guião de Souza Lima Junior

Full Text Available RESUMO: Foram avaliados neste estudo novos sistemas de compostagem de mínimo impacto ambiental para o tratamento in loco de resíduos orgânicos. Dois tipos de composteiras e quatro formas de manejo foram testados. Focaram-se ainda duas composições de resíduos sólidos orgânicos com relação ao aproveitamento energético por aquecimento de água. Os resíduos mantiveram temperaturas termofílicas por mais de 20 dias, apresentaram produção desprezível de metano e não geraram chorume em condições de aeração passiva. Como aspectos de maior influência, podem ser considerados: a suspensão das composteiras sobre pallets, a composição dos resíduos, as condições de contorno das composteiras e o manejo adotado. No teste de recuperação energética, temperaturas de até 51ºC foram alcançadas após 24 horas de circulação de água no sistema, sugerindo que o processo pode ser uma fonte potencial de economia de energia. O modelo de compostagem proposto é ambientalmente adequado, porque minimiza emissões e geração de lixiviado se comparado a aterros sanitários e plantas de compostagem industrial, sendo indicado para cozinhas industriais, condomínios, shopping centers e outros geradores em pequena e média escalas.

Providing clean and affordable energy services to the more than 1 billion people globally who lack access to electricity is a critical driver for poverty reduction, economic development, improved health, and social outcomes. More than 84% of populations without electricity are located in rural areas where traditional grid extension may not be cost-effective; therefore, distributed energy solutions such as mini-grids are critical. To address some of the root challenges of providing safe, quality, and financially viable mini-grid power systems to remote customers, the U.S. Department of Energy (DOE) teamed with the National Renewable Energy Laboratory (NREL) to develop a Quality Assurance Framework (QAF) for isolated mini-grids. The QAF for mini-grids aims to address some root challenges of providing safe, quality, and affordable power to remote customers via financially viable mini-grids through two key components: (1) Levels of service: Defines a standard set of tiers of end-user service and links them to technical parameters of power quality, power availability, and power reliability. These levels of service span the entire energy ladder, from basic energy service to high-quality, high-reliability, and high-availability service (often considered 'grid parity'); (2) Accountability and performance reporting framework: Provides a clear process of validating power delivery by providing trusted information to customers, funders, and/or regulators. The performance reporting protocol can also serve as a robust monitoring and evaluation tool for mini-grid operators and funding organizations. The QAF will provide a flexible alternative to rigid top-down standards for mini-grids in energy access contexts, outlining tiers of end-user service and linking them to relevant technical parameters. In addition, data generated through implementation of the QAF will provide the foundation for comparisons across projects, assessment of impacts, and greater confidence that

The MiniCAM, short for the Mini-Climate Assessment Model, is an integrated assessment model of moderate complexity focused on energy and agriculture sectors. The model produces emissions of greenhouse gases (carbon dioxide, methane and nitrous oxide) and other radiatively important substances such as sulfur dioxide. Through incorporation of the simple climate model MAGICC, the consequences of these emissions for climate change and sea-level rise can be examined. The MiniCAM is designed to be fast and flexible.

Mental adjustment and coping affect the physical outcome and survival as well as quality of life in cancer patients. The Mini-Mental Adjustment to Cancer (Mini-MAC) scale is a new refined, economical and reliable self-rating instrument measuring cognitive and behavioral responses to cancer. The aim of this study was to evaluate the psychometric properties of the Mini-MAC in Korean cancer patients. A total of 208 cancer patients recruited from the Yonsei Cancer Center were assessed with the Mini-MAC and the Hospital Anxiety and Depression Scale (HADS). Principal component analysis with varimax rotation for the Korean version of Mini-MAC (K-Mini-MAC) confirmed four factors. Three had psychometric properties similar to Helpless-Hopeless (HH), Anxious Preoccupation (AP) and Cognitive Avoidance (CA) of the original Mini-MAC. A novel factor, named Positive Attitude, included items of both Fatalism (FA) and Fighting Spirit (FS) from the original version. The five subscales from the original version (AP, HH, FS, FA and CA) and Positive Attitude had acceptable internal reliabilities in our sample (Cronbach's alpha coefficient 0.50-0.86; correlation coefficient of test-retest 0.68-0.88). For the validity, significant interscale correlation was observed in the original five subscales and Positive Attitude. Each subscale including Positive Attitude was also significantly related to Depression and Anxiety of HADS. As a whole, the K-Mini-MAC was a reliable, valid and acceptable tool for Korean cancer patients. These findings can provide information about the cross-cultural validity of Mini-MAC scale's factor structure. Cultural differences were also discussed.

The Psychometrics of the Mini-K.

Many published studies have employed the Mini-K to measure a single fast-slow life history dimension. However, the internal structure of the Mini-K has not been determined and it is not clear that a single higher order K-factor fits the data. It is also not clear that the Mini-K is measurement invariant across groups such as the sexes. To establish the construct validity of K as well as the broader usefulness of applying life history theory to humans, it is crucial that these psychometric issues are addressed as a part of measure validation efforts. Here we report on three studies that used latent variable modeling and data drawn from two college student samples ( ns = 361 and 300) to elucidate the psychometrics of the Mini-K. We found that (a) the Mini-K had a six dimensional first-order structure, (b) the K-factor provided a parsimonious explanation of the associations among the lower order factors at no significant cost to fit, (c) the Mini-K measured the same K-factor across the sexes, (d) K-factor means did not have the same meaning across the sexes and thus the first-order factors should be used in studies of mean sex differences, and finally, (e) the K-factor was only associated with environment and aspects of mating competition in females. Implications and future directions for life history research are discussed.

Full Text Available O artigo discute as relações entre cultura do sucesso e sexualidade, com foco na infância - tema caro às diferentes mídias, como a televisão e o cinema. Faz-se uma análise do filme Pequena Miss Sunshine, a partir de autores como Foucault, Alain Badiou, Ismail Xavier e Jurandir Costa, com ênfase nos conceitos de modos de subjetivação, imagem fílmica e subjetividade exterior. O objetivo é pensar questões de gênero e sexualidade na cultura do espetáculo, a partir de uma narrativa cinematográfica em que tais valores são questionados. A ênfase é dada à análise do olhar e do corpo infantil, na figura da personagem Olive, de modo a pensar a gestualidade própria da criança, em seu silêncio, enigma e mistério, mais do que mera revelação de sentidos. O texto aponta que tal exercício pode sugerir outros modos de pensar as relações entre mídia, infância e questões de gênero e sexualidade.This article explores the relations between the culture of success and sexuality, with a focus on childhood as an important issue for the different kinds of media, such as television and the cinema. An analysis of the movie Little Miss Sunshine is developed, with the use of theoretical references from Foucault, Alain Badiou, Jurandir Costa and Ismail Xavier, about the concepts of audiovisual images, ways of subjectivation and external subjectivity. The aim of the study is to reflect on gender and sexuality issues in a spectacle culture, from a movie narrative in which such values are questioned. There is an analysis of children's bodies and their way of seeing the world, as expressed by the character Olive, with gestures, silence and mystery, rather than a revelation of senses. Such practices may suggest other ways of considering the relations between media, childhood and gender and sexuality issues.

Makinen, Janice V.; Bue, Grant C.; Campbell, Colin; Petty, Brian; Craft, Jesse; Lynch, William; Wilkes, Robert; Vogel, Matthew

2015-01-01

The next-generation Advanced Extravehicular Mobility Unit (AEMU) Portable Life Support System (PLSS) is integrating a number of new technologies to improve reliability and functionality. One of these improvements is the development of the Auxiliary Cooling Loop (ACL) for contingency crewmember cooling. The ACL is a completely redundant, independent cooling system that consists of a small evaporative cooler--the Mini Membrane Evaporator (Mini-ME), independent pump, independent feedwater assembly and independent Liquid Cooling Garment (LCG). The Mini-ME utilizes the same hollow fiber technology featured in the full-sized AEMU PLSS cooling device, the Spacesuit Water Membrane Evaporator (SWME), but Mini-ME occupies only approximately 25% of the volume of SWME, thereby providing only the necessary crewmember cooling in a contingency situation. The ACL provides a number of benefits when compared with the current EMU PLSS contingency cooling technology, which relies upon a Secondary Oxygen Vessel; contingency crewmember cooling can be provided for a longer period of time, more contingency situations can be accounted for, no reliance on a Secondary Oxygen Vessel (SOV) for contingency cooling--thereby allowing a reduction in SOV size and pressure, and the ACL can be recharged-allowing the AEMU PLSS to be reused, even after a contingency event. The first iteration of Mini-ME was developed and tested in-house. Mini-ME is currently packaged in AEMU PLSS 2.0, where it is being tested in environments and situations that are representative of potential future Extravehicular Activities (EVA's). The second iteration of Mini-ME, known as Mini-ME2, is currently being developed to offer more heat rejection capability. The development of this contingency evaporative cooling system will contribute to a more robust and comprehensive AEMU PLSS.

A análise conjugada destes parâmetros, de índices morfométricos e de dados físico-químicos das águas indicam que as bacias em áreas de relevo mais suave tendem a apresentar menores coeficientes de recessão e maiores volumes de fluxo de base. Portanto, nestas áreas o potencial hídrico é maior, já que a vazão das drenagens se mantém por mais tempo na estação seca. O relevo mais suave, com solo mais espesso e maior tempo de trânsito das águas subterrâneas, também justificam as águas mais redutoras e com maiores condutividades elétricas. Os dados também sugerem que as bacias da área com maiores proporções de florestas tendem a apresentar menores fluxos de base por conta das maiores taxas de evapotranspiração. Os métodos aplicados se mostraram adequados para caracterizar o regime hídrico de pequenas bacias hidrográficas e podem ser importantes para a gestão de recursos hídricos.

MINI-THESAURUS, Energy Data Base Subject Thesaurus Generator

International Nuclear Information System (INIS)

Paulk, J.W.

1 - Description of program or function: MINI-THESAURUS allows the user to subset into highly-specialized 'mini-thesauri' the Energy Data Base (EDB) Subject Thesaurus, which contains the standard vocabulary of indexing terms (descriptors) developed and structured by the Office of Scientific and Technical Information (OSTI) for the building and maintenance of the U.S. Department of Energy (DOE) energy information databases. This structured vocabulary reflects the scope of DOE's research, development, and technological programs and encompasses terminology derived not only from the basic sciences but also from the areas of energy, conservation, safety, environmental impact, and regulation. Entire word blocks may be copied from the primary Subject Thesaurus, from another mini-thesaurus, or both, and subsequently modified through the addition of new terms, the deletion of existing terms, and changes to the internal relationships among the word blocks within the mini-thesaurus to create a new, special-purpose thesaurus. MINI-THESAURUS also provides the ability to copy the entire Subject Thesaurus and to treat the copy as a mini-thesaurus, thus allowing one to examine the effects of major changes to the thesaurus structure without having to modify the primary, on-line Thesaurus. The copy operation also optimizes the Subject Thesaurus structure. An interactive user having update privileges for a specific mini-thesaurus and access to the TeX and PostScript proprietary software can produce the mini-thesaurus in printed publication format. Once the mini-thesaurus has been published, periodic supplements may be generated based on date of entry or change maintained by the Thesaurus software. 2 Restrictions on the complexity of the problem: The system enforces the OSTI rules for Thesaurus development

"As moedas dos índios": um estudo de caso sobre os significados do patrimônio arqueológico para os moradores da Vila de Joanes, ilha de Marajó, Brasil

Full Text Available O artigo apresenta os resultados iniciais do projeto de Arqueologia Pública conduzido pela autora em Joanes - uma pequena vila de pescadores na ilha de Marajó, estado do Pará, Brasil -, considerando as ruínas de um sítio histórico (PA-JO-46 associado a uma missão religiosa instalada na vila por volta da segunda metade do século XVII. As reflexões sobre as percepções das comunidades locais acerca do sítio sublinham o entendimento da lógica subjacente ao ato de colecionar artefatos - prática local comum - e à formação de pequenas 'coleções domésticas'. Meu argumento é de que o colecionamento, nesses contextos, não pode ser classificado como ato de destruição, mas como uma forma singular de fruição do passado e do patrimônio. Acredito que essa discussão contribua para a compreensão das relações entre comunidades de pequena escala e o patrimônio arqueológico na Amazônia.

Spurious RF signals emitted by mini-UAVs

2016-10-01

This paper presents experimental work on the detection of spurious RF emissions of mini Unmanned Aerial Vehicles (mini-UAV). Many recent events have shown that mini-UAVs can be considered as a potential threat for civil security. For this reason the detection of mini-UAVs has become of interest to the sensor community. The detection, classification and identification chain can take advantage of different sensor technologies. Apart from the signatures used by radar and electro-optical sensor systems, the UAV also emits RF signals. These RF signatures can be split in intentional signals for communication with the operator and un-intentional RF signals emitted by the UAV. These unintentional or spurious RF emissions are very weak but could be used to discriminate potential UAV detections from false alarms. The goal of this research was to assess the potential of exploiting spurious emissions in the classification and identification chain of mini-UAVs. It was already known that spurious signals are very weak, but the focus was on the question whether the emission pattern could be correlated to the behaviour of the UAV. In this paper experimental examples of spurious RF emission for different types of mini-UAVs and their correlation with the electronic circuits in the UAVs will be shown

Mini-Sniffer III on Lakebed

1976-01-01

The third remotely-piloted Mini-Sniffer research vehicle rests on the lakebed adjacent to the Dryden Flight Research Center, Edwards, California. This view shows the wing shape, hydrazine engine, and the tail booms. The Mini-Sniffer was a remotely controlled, propeller-driven vehicle developed at the NASA Flight Research Center (which became the Dryden Flight Research Center, Edwards, California, in 1976) as a potential platform to sample the upper atmosphere for pollution. The vehicle, flown from 1975 to 1977, was one of the earliest attempts by NASA to develop an aircraft that could sense turbulence and measure natural and human-produced atmospheric pollutants at altitudes above 80,000 feet with a variable-load propeller that was never flight-tested. Three Mini-Sniffer vehicles were built. The number 1 Mini-Sniffer vehicle had swept wings with a span of 18 feet and canards on the nose. It flew 12 flights with the gas-powered engine at low altitudes of around 2,500 feet. The number 1 vehicle was then modified into version number 2 by removing the canards and wing rudders and adding wing tips and tail booms. Twenty flights were made with this version, up to altitudes of 20,000 feet. The number 3 vehicle had a longer fuselage, was lighter in weight, and was powered by the non-air-breathing hydrazine engine designed by NASA's Johnson Space Center in Houston, Texas. This version was designed to fly a 25-pound payload to an altitude of 70,000 feet for one hour or to climb to 90,000 feet and glide back. The number 3 Mini-Sniffer made one flight to 20,000 feet and was not flown again because of a hydrazine leak problem. All three versions used a pusher propeller to free the nose area for an atmospheric-sampling payload. At various times the Mini-Sniffer has been considered for exploration in the carbon dioxide atmosphere of the planet Mars, where the gravity (38 percent of that on Earth) would reduce the horsepower needed for flight.

Full Text Available Apesar do grande desenvolvimento e disseminação da tecnologia de Comando Numérico (CN, a programação de máquinas-ferrramenta ainda é uma tarefa difícil em algumas empresas. Este fato é confirmado pela baixa usabilidade de algumas interfaces CN e pela dificuldade de integrá-las aos sistemas a montante, por exemplo o CAD. Neste artigo, esse problema é tratado tendo como cenário pequenas empresas que ainda empregam a programação manual na fabricação de peças de baixa complexidade. Um protótipo de um software de baixo custo foi desenvolvido para possibilitar a programação CN baseada em microcomputadores. A implementação foi fundamentada em features de programação e dedicada à sintaxe de um comando comercial. Demonstrou-se que essa alternativa propicia uma grande redução de tempo quando comparada à programação manual. Além disso, sua curva de aprendizagem é extremamente reduzida em relação às tecnologias de ponta para manufatura, como por exemplo os sistemas CAM.Despite of the high development and dissemination of Numerical Control (NC, the programming of machine tools remains a hard task in some companies. This fact is confirmed by a low usability of some NC interfaces and the difficulty to integrate them to an upstream system, such a CAD one. In this paper we address this problem, taking with scenario small companies which still use manual programming and supply low complexity geometrical parts. For this group was developed a low cost software that allows a PC-based programming, instead of a direct one. This software was based on programming features and directed to a specific CNC syntax. It was demonstrated that the proposed alternative leads to a significant time reduction when compared to manual programming. Furthermore, its learning curve is smaller than that observed in high-end CAM's.

Mini-tablets have potential applications as a flexible drug delivery tool in addition to their generally perceived use as multi-particulates. That is, mini-tablets could provide flexibility in dose finding studies and/or allow for combination therapies in the clinic. Moreover, mini-tablets with well controlled quality attributes could be a prudent choice for administering solid dosage forms as a single unit or composite of multiple mini-tablets in patient populations with swallowing difficulties (e.g., pediatric and geriatric populations). This work demonstrated drug substance particle size and concentration ranges that achieve acceptable mini-tablet quality attributes for use as a single or composite dosage unit. Immediate release and orally disintegrating mini-tablet formulations with 30μm to 350μm (particle size d 90 ) acetaminophen and Compap™ L (90% acetaminophen) at concentrations equivalent to 6.7% and 26.7% acetaminophen were evaluated. Mini-tablets achieved acceptable weight variability, tensile strength, friability, and disintegration time at a reasonable solid fraction for each formulation. The content uniformity was acceptable for mini-tablets of 6.7% formulations with ≤170μm drug substance, mini-tablets of all 26.7% formulations, and composite dosage units containing five or more mini-tablets of any formulation. Results supported the manufacturing feasibility of quality mini-tablets, and their applicability as a flexible drug delivery tool. Copyright © 2017 Elsevier B.V. All rights reserved.

Large group counseling sessions for soldiers following battle have been commonly used since World War II. The author conceptualizes and demonstrates how these mini-marathon sessions can be adapted to support all ages and types of civilians involved in disasters. Mini-marathons take about 3 hours and are divided into three sections: story sharing, symptom sharing, and suggestions for self-help, including sharing tales of heroism and survival. After an initial mini-marathon session, a second session may be held emphasizing creativity. The author also describes how mini-marathons can be adapted for therapists who will lead their own sessions.

The use of mini-samples in palaeomagnetism

Böhnel, Harald; Michalk, Daniel; Nowaczyk, Norbert; Naranjo, Gildardo Gonzalez

2009-10-01

Rock cores of ~25 mm diameter are widely used in palaeomagnetism. Occasionally smaller diameters have been used as well which represents distinct advantages in terms of throughput, weight of equipment and core collections. How their orientation precision compares to 25 mm cores, however, has not been evaluated in detail before. Here we compare the site mean directions and their statistical parameters for 12 lava flows sampled with 25 mm cores (standard samples, typically 8 cores per site) and with 12 mm drill cores (mini-samples, typically 14 cores per site). The site-mean directions for both sample sizes appear to be indistinguishable in most cases. For the mini-samples, site dispersion parameters k on average are slightly lower than for the standard samples reflecting their larger orienting and measurement errors. Applying the Wilcoxon signed-rank test the probability that k or α95 have the same distribution for both sizes is acceptable only at the 17.4 or 66.3 per cent level, respectively. The larger mini-core numbers per site appears to outweigh the lower k values yielding also slightly smaller confidence limits α95. Further, both k and α95 are less variable for mini-samples than for standard size samples. This is interpreted also to result from the larger number of mini-samples per site, which better averages out the detrimental effect of undetected abnormal remanence directions. Sampling of volcanic rocks with mini-samples therefore does not present a disadvantage in terms of the overall obtainable uncertainty of site mean directions. Apart from this, mini-samples do present clear advantages during the field work, as about twice the number of drill cores can be recovered compared to 25 mm cores, and the sampled rock unit is then more widely covered, which reduces the contribution of natural random errors produced, for example, by fractures, cooling joints, and palaeofield inhomogeneities. Mini-samples may be processed faster in the laboratory, which is of

Para la temporada 2005/2006 la Federación Española de Baloncesto propuso unas modificaciones al reglamento, de las cuales destaca una línea de tres puntos con forma rectangular. El objetivo de este trabajo fue analizar la bibliografía con respecto a las modificaciones reglamentarias y a la línea de tres puntos en Minibasket, desde un enfoque formativo para el jugador. Las reglas de los deportes de iniciación y en concreto de Minibasket deben responder a las demandas de los sujetos, sus necesidades y motivaciones con el fin de lograr un aprendizaje óptimo. En este sentido, tras revisar la bibliografía, no se encuentran estudios científicos que se centren en analizar la inclusión de la línea de tres puntos, ni que analicen la posición y distancia a la que se debe situar dicha línea para mejorar el juego en Minibasket. Sin embargo, la inclusión de la línea de tres puntos, en las competiciones de las cuales se ha encontrado referencias, fue todo un éxito. Por lo que son necesarias investigaciones que ayuden a esclarecer las limitaciones que existen a la hora de proponer una línea de tres puntos, adaptada a las necesidades formativas y a las características de los jugadores de Minibasket, para favorecer el lanzamiento y obtener éxito desde posiciones alejadas.

Jiang Peixue; Xu Ruina

2007-01-01

Forced convection heat transfer of air and water in bronze and pure copper mini-fin structures and mini-channel structures was investigated experimentally. The mini-fin dimensions were 0.7 mm x 0.2 mm and 0.8 mm x 0.4 mm. The tests included both staggered diamond-shaped and in-line square mini-fin arrangements. The tests investigated the effects of structures, mini-fin dimensions and arrangement, test section materials, and fluid properties on the convection heat transfer and heat transfer enhancement. For the tested conditions, the convection heat transfer coefficient was increased 9-21 fold for water and 12-38 fold for air in the mini-fin structures compared with an empty plate channel. The friction factor and flow resistance in the mini-channel structures and the in-line square mini-fin arrangement were much less than in the staggered diamond-shaped mini-fin arrangement. For the small channel width, W c = 0.2 mm, the convection heat transfer with the in-line square array structure was more intense than with the staggered diamond-shaped structure, the mini-channel structure or the porous media. For the larger channel width, W c = 0.4 mm, the convection heat transfer in the staggered diamond-shaped array structure was more intense than in the others systems while the in-line square structure had the best overall thermal-hydraulic performance

Mini-split heat pumps can provide space heating and cooling in many climates and are relatively affordable. These and other features make them potentially suitable for retrofitting into multifamily buildings in cold climates to replace electric resistance heating or other outmoded heating systems. This report investigates the suitability of mini-split heat pumps for multifamily retrofits. Various technical and regulatory barriers are discussed and modeling was performed to compare long-term costs of substituting mini-splits for a variety of other heating and cooling options. A number of utility programs have retrofit mini-splits in both single family and multifamily residences. Two such multifamily programs are discussed in detail.

Mini-LIA is a miniature of a linear induction accelerator developed by China Academy of Engineering Physics and Tsinghua University in 2007. It has been constructed with a thermionic cathode in an electron injector and a metglas core in the induction accelerator cavities. A double-pulsed electron beam was produced for the first time in China on the Mini-LIA with a thermionic cathode in the electron gun and a metglas core in the induction accelerator cavities. A double-pulsed beam current of more than 1.1A was obtained on condition of 80 kV double-pulsed high voltage produced by pulsed power system supplying to the injector and accelerating modules. Some primary experiments for measuring the parameters of Mini-LIA has been performed, and some beam characterizations of Mini-LIA are presented. Further improvement is underway. (authors)

Background Dementia is considered widely under-detected in primary care, and general practitioners (GPs) frequently ask for easy to use tools to assist in its early detection.Aim To determine the degree of correlation between the Mini-Cog Assessment (Mini-Cog) as performed by GPs and the Mini-Mental State Examination (MMSE).Design of study This was a prospective study (2005, 2006) comparing two cognitive screening instruments.Setting Ten general practices in Austria, with patients with a hitherto undiagnosed suspicion of dementia seen consecutively.Method Sensitivity, specificity and positive and negative predictive values (PPVs and NPVs) of the Mini-Cog (applying both a colour-coded and the original rating method) were assessed for degree of correlation with the MMSE. In phase one GPs examined patients suspected of having dementia using the Mini-Cog; in phase two a neurologist retested them applying the MMSE, a clock-drawing test (CDT) and a routine clinical examination. A questionnaire on the practicability of the Mini-Cog was answered by GPs.Results Of the 107 patients who participated 86 completed the whole study protocol. The Mini-Cog, as performed by the ten GPs, displayed a sensitivity of 0.85 (95% CI: 0.71, 0.98), a specificity of 0.58 (95% CI: 0.46, 0.71), a PPV of 0.47 (95% CI: 0.33, 0.61) and an NPV of 0.90 (95% CI: 0.80, 0.99) as against the MMSE carried out by neurologists. The GPs judged the Mini-Cog useful and time saving.Conclusion The Mini-Cog has a high sensitivity and acceptable specificity in the general practice setting and has proved to be a practicable tool for the diagnosis of dementia in primary care.

Full Text Available Nos últimos anos, globalização tornou-se uma palavra-chave para a organização do nosso pensamento acerca das mudanças na economia mundial contemporânea. Observa-se que o processo de globalização está conduzindo a uma profunda reorganização do capitalismo e do papel que determinadas áreas geográficas, como Estados ou regiões, desempenham dentro do sistema. Como resultado, o interesse no papel das economias externas e dos efeitos de cooperação no desenvolvimento regional cresceu expressivamente nos anos 90, influenciado pelo sucesso da experiência italiana de distritos industriais de pequenas firmas. Muitos estudos de caso têm mostrado que a aglomeração produz uma eficiência coletiva que pode ajudar as pequenas empresas locais a superarem as restrições de crescimento. Este trabalho relata os resultados de uma análise empírica de três distritos calçadistas do Estado da Paraíba (cobrindo 38 empresas. Mostrando que nesses distritos existe uma enorme heterogeneidade de tamanho e desempenho. As firmas desenvolvem diferentes tipos de flexibilidade com respeito à produção, tecnologia e a emprego, de forma que nem sempre correspondem ao tipo ideal sugerido no modelo de distrito industrial.

Full Text Available O objetivo do trabalho foi o de estudar o processo estratégico, testar algumas hipóteses acerca desse processo e propor modelos explicativos para a criação de estratégia em pequenas empresas de base tecnológica. A estratégia empresarial é uma área de significativa importância para os estudos administrativos, tendo em vista o impacto das decisões e ações estratégicas para o sucesso das empresas. Além disso, a teoria sobre estratégia está fortemente fundamentada em estudos realizados em empresas de grande porte, maduras, podendo, portanto, apresentar viés quando considerada a sua aplicação em empresas de pequeno porte e empresas em fase de desenvolvimento. Este estudo analisou os processos de criação de estratégias e propôs um conjunto de modelos representativos desses processos para pequenas empresas de base tecnológica criadas sem a formalização de planos de negócios, o que foi muito comum no início dos polos tecnológicos brasileiros na década de 80. Foi realizado um trabalho de campo cuja natureza foi a de pesquisa aplicada. O procedimento técnico utilizado foi o estudo multicasos, sendo investigadas cinco empresas de pequeno e uma de médio porte, conforme classificação pelo número de empregados, todas de base tecnológica e localizadas no Polo Tecnológico de São Carlos, em São Carlos, SP. O resultado da pesquisa evidenciou que as estratégias são criadas por etapas distintas, o que permitiu a construção de um conjunto de modelos representativos do processo de criação de estratégias, além de confirmar algumas hipóteses formuladas, podendo destacar que a ausência de formalização de planos de negócios não impediu o sucesso das empresas estudadas.The aim of this study was to analyze the strategic process and to propose a model that represents this process in small technology-based companies created without a business plan, which was very common in the beginning of a Brazilian Technopolis

Full Text Available In this paper we discuss implementation of a mini-Unmanned Aerial Vehicle (UAV vertical take-off and landing (VTOL platform for surveying activities related to highway construction. Recent advances in sensor and communication technologies have allowed scaling sizes of unmanned aerial platforms, and explore them for tasks that are economical and safe over populated or inhabited areas. In highway construction the capability of mini-UAVs to survey in hostile and/or hardly accessible areas can greatly reduce human risks. The project focused on developing a cost effective, remotely controlled, fuel powered mini-UAV VTOL (helicopter platform with certain payload capacity and configuration and demonstrated its use in surveying and monitoring activities required for highway planning and construction. With an on-board flight recorder global positioning system (GPS device, memory storage card, telemetry, inertial navigation sensors, and a video camera the mini-UAV can record flying coordinates and relay live video images to a remote ground receiver and surveyor. After all necessary integration and flight tests were done the mini-UAV helicopter was tested to operate and relay video from the areas where construction was underway. The mini-UAV can provide a platform for a range of sensors and instruments that directly support the operational requirements of transportation sector.

In this work the design of a mini subcritical nuclear reactor formed by means of light water moderator, uranium as fuel, and isotopic neutron source of {sup 239}PuBe was carried out. The design was done by Monte Carlo methods with the code MCNP5 in which uranium was modeled in an array of concentric holes cylinders of 8.5, 14.5, 20.5, 26.5, 32.5 cm of internal radius and 3 cm of thickness, 36 cm of height. Different models were made from a single fuel cylinder (natural uranium) to five. The neutron source of {sup 239}PuBe was situated in the center of the mini reactor; in each arrangement was used water as moderator. Cross sections libraries Endf/Vi were used and the number of stories was large enough to ensure less uncertainty than 3%. For each case the effective multiplication factor k{sub e}-f{sub f}, the amplification factor and the power was calculated. Outside the mini reactor the ambient dose equivalent H (10) was calculated for different cases. The value of k{sub eff}, the amplification factor and power are directly related to the number of cylinders of uranium as fuel. Although the average energy of the neutrons {sup 239}PuBe is between 4.5 and 5 MeV in the case of the mini reactor for a cylinder, in the neutron spectrum the presence of thermal neutrons does not exist, so that produced fissions are generated with fast neutrons, and in designs of two and three rings the neutron spectra shows the presence of thermal neutrons, however the fissions are being generated with fast neutrons. Finally in the four and five cases the amount of moderator is enough to thermalized the neutrons and thereby produce the fission. The maximum value for k{sub eff} was 0.82; this value is very close to the assembly of Universidad Autonoma de Zacatecas generating a k{sub eff} of 0.86. According to the safety and radiation protection standards for the design of mini reactor of one, two and three cylinders they comply with the established safety, while designs of four and five

Supplementary to the description of diseases at symptom level, the International Classification of Functioning, Disability and Health (ICF), edited by the WHO, for the first time enables a systematic description also at the level of disabilities and impairments. The Mini-ICF-Rating for Mental Disorders (Mini-ICF-P) is a short observer rating instrument for the assessment of disabilities, especially with regard to occupational functioning. The Mini-ICF-P was first evaluated empirically in 125 patients of a Department of Behavioural Medicine and Psychosomatics. Parallel-test reliability was r = 0.59. Correlates were found with cognitive and motivational variables and duration of sick leave from work. In summary, the Mini-ICF-P is a quick and practicable instrument.

The aim of this study was to assess the specificities of the Mini-Cog, the Clock Drawing Test (CDT), and the Mini-Mental State Examination (MMSE) against depression and healthy controls in a German Memory Clinic. Furthermore, we analyzed the specificities of all three screening instruments in dependence of actual depression severity. Data from 142 depressed elderly, 438 dementia patients, and 64 healthy controls were retrospectively analyzed. The CDT and an extraction of the three-item recall of the MMSE were used to constitute the Mini-Cog algorithm. Depression severity was rated by either the Beck Depression Inventory (BDI) or the Geriatric Depression Scale (GDS) depending on the age of the patients. The Mini-Cog achieved a specificity of 79.6% against depressed elderly and 100.0% against healthy subjects (p Mini-Cog and the CDT, but also showed the lowest sensitivity for the detection of dementia. Surprisingly, the depression severity had no effect on the specificity of the Mini-Cog and the CDT, only the MMSE was susceptible for the depression severity. Although the MMSE showed higher specificities, the weighting between the sensitivities and specificities in all tests prove again the Mini-Cog as a short, valid, and sensitive screening tool.

Full Text Available OBJETIVO: A tuberculose é uma das maiores causas de mortalidade no mundo, porém seus efeitos econômicos são pouco conhecidos. O objetivo do estudo foi o de estimar os custos do tratamento e prevenção da tuberculose para o sistema de saúde (público e privado e para as famílias. MÉTODOS: O estudo foi realizado no município de Salvador, BA, em 1999. Os dados para estimação dos custos para o sistema de saúde foram coletados nas secretarias de saúde, centros de saúde e em uma entidade filantrópica. Os custos públicos e privados foram estimados pela metodologia da contabilidade de custos. Os dados de custos para as famílias foram coletados por meio de questionários e incluem despesas com transporte, alimentação e outros, bem como as perdas de renda associadas à doença. RESULTADOS: O custo médio para tratamento de um caso novo de tuberculose foi de aproximadamente R$186,00 (US$103; para o tratamento de um paciente multiresistente o custo foi 27 vezes mais alto. Os custos para o serviço público corresponderam a 65% em internações, 32% em tratamento e apenas 3% em prevenção. As famílias comprometeram cerca de 33% da sua renda com despesas relacionadas a tuberculose. CONCLUSÕES: Apesar do fato das famílias não terem que pagar por medicamentos e tratamento, dado que este serviço é oferecido pelo Estado, os custos familiares ligados a perda de rendimentos devido a doença foram muito elevados. A proporção utilizada em prevenção pelo serviço público é pequena. Um maior investimento em campanhas de prevenção poderia não somente diminuir o número de casos, mas também, levar a um diagnósticos precoce, diminuindo os custos associados à hospitalização. A falta de um sistema integrado de custos não permite a visualização dos custos nos diversos setores.

Full Text Available A crescente pesquisa em gestão da inovação incita a necessidade de medir o desempenho proporcionado pelas variadas ações de inovação. No entanto a medição de desempenho da inovação, especialmente da inovação de produto, encontra-se ainda dispersa em uma variedade de modos, seja quanto as suas entradas e saídas e/ou ainda quanto a utilizar-se dados objetivos e subjetivos. A replicação de métodos tradicionais de mensuração do desempenho da inovação de produto que não consideram os diversos resultados da inovação de produtos para a organização, agrava a questão de medida do desempenho da inovação de produto. Neste sentido, o presente estudo visa avaliar a validade e confiabilidade de uma escala multidimensional proposta por Hanachi (2015 que considera medidas de percepção, bem como o desempenho da inovação de produto como um output, para aplicação em Pequenas e Médias Empresas (PME do setor industrial. A pesquisa é de caráter descritivo, de tipo survey e com corte transversal. A aplicação da escala de desempenho da inovação do produto foi realizada com 94 gestores de pequenas e médias indústrias do setor têxtil. Para a realização da análise empregou-se os softwares Statistica® e SPSS 2.0 onde se realizaram os testes de unidimensionalidade e confiabilidade dos constructos e posterior aplicação da análise fatorial. O resultado aponta à pertinência e aplicabilidade da escala proposta e disponibiliza uma escala válida para novos estudos que buscarem relacionar desempenho da inovação de produto com outros construtos apresentados na literatura.

The elderly population is increasing around the world, and the prevalence of dementia increases with age. Hence, it is expected that the number of people with dementia will increase significantly in the coming years. The Mini-Mental Status Examination - 2 (MMSE-2) and Mini-Cog are widely used tests to screen for dementia. These scales have good reliability and validity and are easy to administer in clinical and research settings. The purpose of this study was to validate the Arabic versions of MMSE-2 and Mini-Cog. These scales were assessed against the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision ( DSM-IV-TR ) criteria for dementia, as the gold standard. The standard versions of the MMSE-2 and Mini-Cog were translated to Arabic following the back-translation method. Then, a trained rater administered these tests to 134 Arab elderly aged >60 years. A physician, blind to the results of these two tests, assessed the participants for vascular dementia or probable Alzheimer's disease, based on the DSM-IV-TR criteria. The sample included 67.2% Qataris. The mean age was 74.86 years (standard deviation =7.71), and 61.9% did not attend school. The mean of the adjusted scores of MMSE-2 based on age and education level was 19.60 (standard deviation =6.58). According to DSM-IV-TR , 17.2% of the participants had dementia. Sensitivity and specificity of the MMSE-2 and the Mini-Cog together were 71.4% and 61.6%, respectively, which were better than those of each test alone. Together, the Arabic versions of MMSE-2 and Mini-Cog are good screening tools for cognitive impairment in Arabs.

Reasons for mini-implants failure: choosing installation site should be valued!

Directory of Open Access Journals (Sweden)

Alberto Consolaro

2014-04-01

Full Text Available Mini-implant loss is often associated with physical and mechanical aspects that result from choosing an inappropriate placement site. It is worth highlighting that: a Interdental alveolar bone crests are flexible and deformable. For this reason, they may not offer the ideal absolute anchorage. The more cervical the structures, the more delicate they are, thus offering less physical support for mini-implant placement; b Alveolar bone crests of triangular shape are more deformable, whereas those of rectangular shape are more flexible; c The bases of the alveolar processes of the maxilla and the mandible are not flexible, for this reason, they are more likely to receive mini-implants; d The more cervical a mini-implant is placed, the higher the risk of loss; the more apical a mini-implant is placed, the better its prognosis will be; e 3D evaluations play a major role in planning the use of mini-implants. Based on the aforementioned considerations, the hypotheses about mini-implant loss are as follows: 1 Deflection of maxillary and mandibular alveolar processes when mini-implants are more cervically placed; 2 Mini-implants placed too near the periodontal ligament, with normal intra-alveolar tooth movement; 3 Low bone density, low thickness and low alveolar bone volume; 4 Low alveolar cortical bone thickness; 5 Excessive pressure inducing trabecular bone microfracture; 6 Sites of higher anatomical weakness in the mandible and the maxilla; 7 Thicker gingival tissue not considered when choosing the mini-implant.

Congenital hypogonadotropic hypogonadism: implications of absent mini-puberty.

Science.gov (United States)

Dwyer, Andrew A; Jayasena, Channa N; Quinton, Richard

2016-06-01

The phenomenon known as "mini-puberty" refers to activation of the neonatal hypothalamo-pituitary axis causing serum concentrations of gonadotrophins and testosterone (T) to approach adult male levels. This early neonatal period is a key proliferative window for testicular germ cells and immature Sertoli cells. Although failure to spontaneously initiate (adolescent) puberty is the most evident consequence of a defective gonadotropin-releasing hormone (GnRH) neurosecretory network, absent mini-puberty is also likely to have a major impact on the reproductive phenotype of men with congenital hypogonadotrophic hypogonadism (CHH). Furthermore, the phase of male mini-puberty represents a key window-of-opportunity to identify congenital GnRH deficiency (either isolated CHH, or as part of combined pituitary hormone deficiency) in childhood. Among male neonates exhibiting "red flag" indicators for CHH (i.e. maldescended testes with or without cryptorchidism) a single serum sample (between 4-8 weeks of life) can pinpoint congenital GnRH deficiency far more rapidly and with much greater accuracy than dynamic tests performed in later childhood or adolescence. Potential consequences for missing absent mini-puberty in a male neonate include the lack of monitoring of pubertal progression/lack of progression, and the missed opportunity for early therapeutic intervention. This article will review our current understanding of the mechanisms and clinical consequences of mini-puberty. Furthermore, evidence for the optimal clinical management of patients with absent mini-puberty will be discussed.

This paper presents a computing tool called Virtual Laboratory de Minirredes (Virtual Laboratory of Mini-grids). Using the virtual environment of the developed tool, it is possible to make remote connection/disconnection of switches and loads (resistive, inductive, capacitive and non-linear) at strategic points of the electric mini-grid with hybrid distributed generation systems (solar photovoltaic-diesel). The mini-grid has a length of about 1 km and is installed in the test area of the Grupo de Estudios e Desenvolvimento de Alternativas Exergética (GEDAE) of the Universidade Federal do Pará, located in the city of Belém, Pará, Brazil. The developed tool has communication functions with electric parameters transducers and programmable logic controllers (PLCs). This communication enables the opening and closing of contactors, resulting in different settings for the mini-grid. In addition to that, based on the proposed configuration by the user, the real-time operation status of mini-grid is presented in a graphic interface (for example, monitored electric parameters, distributed generators connected, status of disconnected switches, etc.) and the acquired data is stored. The use of the computing tool also focuses on the construction of a database, in order to obtain knowledge about the mini-grid performance under various conditions that can be set, depending on the operational strategy adopted, based on the choice of the layout, loads and power sources used in the mini-grid.

Fredrickson, Steven E.; Duran, Steve; Mitchell, Jennifer D.

2004-01-01

The Engineering Directorate of NASA Johnson Space Center has developed a nanosatellite-class free-flyer intended for future external inspection and remote viewing of human spacecraft. The Miniature Autonomous Extravehicular Robotic Camera (Mini AERCam) technology demonstration unit has been integrated into the approximate form and function of a flight system. The spherical Mini AERCam free flyer is 7.5 inches in diameter and weighs approximately 10 pounds, yet it incorporates significant additional capabilities compared to the 35 pound, 14 inch AERCam Sprint that flew as a Shuttle flight experiment in 1997. Mini AERCam hosts a full suite of miniaturized avionics, instrumentation, communications, navigation, imaging, power, and propulsion subsystems, including digital video cameras and a high resolution still image camera. The vehicle is designed for either remotely piloted operations or supervised autonomous operations including automatic stationkeeping and point-to-point maneuvering. Mini AERCam is designed to fulfill the unique requirements and constraints associated with using a free flyer to perform external inspections and remote viewing of human spacecraft operations. This paper describes the application of Mini AERCam for stand-alone spacecraft inspection, as well as for roles on teams of humans and robots conducting future space exploration missions.

Mini-chamber, an advanced protection concept for NIF

Peterson, P.F.; Scott, J.M.

1996-01-01

Inertial confinement fusion (ICF) target debris and ablated near-target materials pose the primary threat to the National Ignition Facility (NIF) final optics debris shields, as well as a major challenge in future inertial fusion energy (IFE) power plants. This work discusses a NIF 'mini-chamber,' designed to mitigate the debris threat. Although the NIF base-line design protects against debris using a frost-protected target positioner and refractory first-wall coatings, the mini-chamber provides important flexibility in three areas: debris-shield protection from beyond-design basis shots (i.e. heavy hohlraums, special diagnostics, shields); fielding of large experiments with significant surface ablation; and studying key ablation and gas-dynamics issues for liquid-wall IFE power plants. Key mini-chamber modeling results are presented, followed by discussion of equipment requirements for fielding a NIF mini-chamber. 7 refs., 3 figs

Many complex cases which would previously have required surgery or functional appliances can now be treated with fixed appliance therapy using mini-implants. A mutilated dentition case where mini-implants were used to provide anchorage for intrusion of molars and retraction of anterior teeth is reported here to illustrate this point.

Energy efficient mini bars in hotel rooms; Energieffektive minibarer til hotelvaerelser

The project 'Energy-efficient mini bars for hotel rooms' is carried out from February December 2005. The project is financed by Elfor's PSO funds and also by the participants in the project, HORESTA and Teknologisk Institut. Mini bars consume up to 10% of the total electricity costs of a hotel. Therefore, the energy consumption of mini bars has been brought into focus in this project. The existing mini bar market has been analysed and measurements have been carried out on the type of mini bars that are used most often. In that way, energy consumption, net volume, energy efficiency, energy labelling, noise level and cooling capacity have been determined. In the course of the project, mini bars from IndelB, Domestic and Vibocold have been tested. With regard to energy consumption, the test results showed large deviations from the consumption stated by the manufacturer. Only 1 of the 6 tested mini bars received an energy label B - the others were labelled with F or G. Therefore, there is a great potential for developing more energy efficient mini bars. A list covering the energy consumption, energy labelling, noise level etc. of the tested mini bars and a guide to new purchases can be found on HORESTA's homepage www.horesta.dk. (au)

Objective. To search for articles evaluating the use of tracheostomies (either permanent stomas or tracheostomy tubes) in adult obstructive sleep apnea (OSA) patients and to evaluate the potential for the use of mini tracheostomies as treatment for OSA. Study Design. Systematic review. Methods. Nine databases were searched from inception through July 21, 2015. Results. The overall tracheostomy search yielded 516 articles, of which eighteen studies provided polysomnographic data. No study was identified (empty review) for the use of mini tracheostomies for treating OSA. The mini tracheostomy search yielded ninety-five articles which describe findings for either mini tracheostomy kits (inner cannula diameter of 4 mm) or the performance of mini tracheotomies. Six articles described the use of mini tracheostomies as a temporary procedure to relieve acute upper airway obstruction and none described the use for OSA. For tracheostomy stomal sites, suturing the skin directly to the tracheal rings with defatting can minimize stomal site collapse. The smallest tracheostomy stomal size that can successfully treat OSA has not been described. Conclusion. Mini tracheostomies as small as 4 mm have been successfully used in the short term to relieve upper airway obstruction. Given that polysomnography data are lacking, additional research is needed.

Conclusion: This study revealed that once the dental surgeon becomes familiar with the procedure, the stability of orthodontic mini-implants depends on the type of mini-implant, age of the patient, implantation site, and the healing time of the mini-implant. Miniplates are a more feasible anchorage system when miniscrews fail repeatedly.

The Mini-Mental Adjustment to Cancer Scale (Mini-MAC) is a 29-item instrument designed to evaluate the responses developed by cancer patients during their mental adjustment to diagnosis and treatment. This study aims to validate the Mini-Mental Adjustment to Cancer Scale (Mini-MAC) translated and adapted to the Portuguese language and culture, in end-of-life cancer patients receiving palliative care. The instrument was administered to 346 Portuguese end-of-life cancer patients, receiving care through outpatient visits or admitted into palliative care units, without cognitive symptoms and with symptoms under control. A cross-sectional validation study using orthogonal rotation through the varimax method followed by convergent and discriminant validity. The analysis of the main components confirms the existence of five factors, demonstrating the validity of the construct, with good internal consistency in the subscales and Cronbach's alpha values between 0.78 and 0.93. Good test-retest reliability was also found, and r values for subscales ranged from 0.62 to 0.99. The instrument proved to be a reliable, valid and sensitive measure in the study of mental adjustment of Portuguese end-of-life patients with cancer receiving palliative care. Nurses can use the Mini-MAC Scale in research and clinical practice in order to evaluate the mental adjustment of Portuguese end-of-life cancer patients receiving palliative care.

Skeletal anchorage with mini-implants has greatly broadened the treatment possibilities in orthodontics over the last few years. To reduce implant failure rates, it is advisable to obtain adequate primary stability. The aim of this study was to quantitatively analyze the impact of implant design and dimension on primary stability. Forty-two porcine iliac bone segments were prepared and embedded in resin. To evaluate the primary stability, we documented insertion torques of the following mini-implants: Aarhus Screw, AbsoAnchor, LOMAS, Micro-Anchorage-System, ORLUS and Spider Screw. In each bone, five Dual Top Screws were inserted for reference purposes to achieve comparability among the specimens. We observed wide variation in insertion torques and hence primary stability, depending on mini-implant design and dimension; the great impact that mini-implant diameter has on insertion torques was particularly conspicuous. Conical mini-implants achieved higher primary stabilities than cylindrical designs. The diameter and design of the mini-implant thread have a distinctive impact on primary stability. Depending on the region of insertion and local bone quality, the choice of the mini-implant design and size is crucial to establish sufficient primary stability.

O recorte espacial é a rede urbana norte-paranaense a partir da década de 1970, quando inúmeras transformações de ordem econômico-social incidiram na rede urbana e de forma singular em algumas pequenas cidades, provocando alterações em seus papéis, como no caso da cidade de Santa Fé. Por intermédio de iniciativas locais, agentes sociais em meio às transformações na agropecuária norte-paranaense concretizaram possibilidades emanadas do todo na forma de prestação de serviços especializados em fotografias e filmes de formaturas, com gênese em 1980 quando foi instalado o primeiro estabelecimento. A lucratividade dessa primeira empresa instalada na cidade criou a perspectiva de implantação de novos estabelecimentos do ramo seja por ex-funcionários ou ex-sócios seja por outros agentes sociais locais oriundos de outras atividades econômicas após a década de 1980. Em 2010 a cidade possuía 48 estabelecimentos especializados em fotografias e filmes de formaturas. Essa especialização funcional na pequena cidade de Santa Fé, complexifica sua inserção na rede urbana norte - paranaense, bem como em outras redes, cujas interações espaciais tornaram-se amplas mediante a instalação de filiais/franquias em vários estados brasileiros.

Mia Couto e a educação de crianças pequenas: Alteridade, arte e infância

Full Text Available The essay presents the proposal of an interlocution between the course of our studies in the field of early childhood education and Mia Couto's work. We address the matter of alterity from themes such as space, time, childhoods, art and science. Mia Couto defines alterity as the magic of being us, being others, a conception that reaffirms the African thinking according to which each person is because we are everybody else. Here, "others" do not refer only to people, but also to the places they inhabit, the listening to their social processes, their traditions, in summary, the lives they live. Mia Couto's reflections lead us to part with instituted habits of thinking the education of childhood by favoring the resistance to the hegemonic way of conceiving and conducting the education of small children from one single way of promoting childhood experiences. Este ensaio apresenta uma proposta de interlocução entre o percurso de nossos estudos no campo da educação da infância e a obra de Mia Couto. Para tanto, detemo-nos na questão da alteridade a partir dos temas espaço, tempo, infâncias, arte e ciência. A alteridade é, para Mia Couto, a magia de sermos nós, sendo outros, concepção que reafirma o pensamento africano na qual cada um é porque é todos os outros. Esses “outros” não se referem apenas a pessoas, mas também aos lugares que habitam, à escuta de seus processos sociais, suas tradições, enfim as vidas que neles são vividas. As reflexões de Mia Couto permitem romper com hábitos instituídos de pensar a educação das infâncias ao favorecerem a resistência ao modo hegemônico de conceber e realizar a educação de crianças pequenas a partir de uma única forma escolar de promover experiências de infância na contemporaneidade.

Mini-mental Parkinson (MMP) as a dementia screening test: comparison with the Mini-Mental State Examination (MMSE).

Larner, Andrew J

2012-07-01

As populations age, screening instruments for cognitive impairment and dementia will become of increasing importance in clinical practice. Mini-Mental Parkinson (MMP), a derivative of the Mini-Mental State Examination (MMSE), was originally described as a cognitive screening instrument for use in Parkinson's disease. Its item content addresses some of the acknowledged shortcomings of the MMSE. Pragmatic use of MMP in general cognitive clinics has not previously been examined. To compare the performance of two scales, Mini-Mental Parkinson (MMP) and the Mini-Mental State Examination (MMSE), as cognitive screening instruments for dementia in a memory clinic population. MMP was administered prospectively to 201 consecutive new patient referrals independent of other tests used to establish dementia diagnosis according to standard diagnostic criteria (DSM-IV). Diagnostic utility of MMP for dementia was measured and compared with MMSE. MMP proved easy to use and acceptable to patients. Optimal test accuracy (0.86) was at MMP cutoff of ≤ 17/32, with sensitivity 0.51, specificity 0.97, positive predictive value 0.83, negative predictive value 0.87, and area under Receiver Operating Characteristic curve 0.89. Using a higher cutoff (≤ 29/32), MMP sensitivity was 1.00 with specificity 0.70. MMP scores correlated with MMSE (r = 0.93) and diagnostic agreement was high (κ = 0.85). MMP is a useful screening instrument in the memory clinic setting, with patients who fall below the designated cutoff requiring further investigation to ascertain a cause for their cognitive impairment.

modelizacion, y aplicacion en convertidores PWM, esta aun por estudiar y valorar. El primer Capitulo consiste en una breve introduccion al problema de la regulacion cruzada y la impedancia cruzada para posteriormente describir las tecnicas de post-regulacion actualmente mas empleadas, con especial atencion al post-regulador con transformador controlado. El Capitulo segundo trata del estudio de las caracteristicas estaticas del postregulador con transformador controlado. Partiendo de los estudios disponibles sobre el postregulador se plantean mejoras en su modo de actuacion y se discuten tres alternativas diferentes para controlar el transformador. Las dos primeras consisten en emplear un convertidor auxiliar Boost en sus dos modos de funcionamiento, continuo y discontinuo. La tercera consiste en controlar el transformador con una tension PWM directamente, sin filtrado. Finalmente se comprueba experimentalmente, para el estado estacionario, el funcionamiento del post-regulador para cada uno de los tres metodos de control. El Capitulo tercero trata de la dinamica de la salida controlada con el post-regulador cuando este emplea un convertidor auxiliar tipo Boost. Mediante la tecnica de promediado de variables de estado se propone el modelo de pequena senal, tanto para el modo continuo como para el modo discontinuo de funcionamiento del convertidor auxiliar. Los resultados mas significativos de esta seccion son las expresiones analiticas de las impedancias cruzadas y de la impedancia de la salida post-regulada. Como complemento al modelo de pequena senal se plantea un modelo de gran senal implementado sobre el simulador Pspice. Con este nuevo modelo se reproducen los resultados obtenidos con el modelo de pequena senal y ademas es posible simular los transitorios en las tensiones de salida ante cambios de carga. La modelizacion del convertidor cuando el transformador se controla con una tension PWM sin filtrar es el objetivo del Capitulo 4. En las secciones siguientes del Capitulo

This study was conducted to estimate screening performance of dementia screening tools including Mini-Mental State Examination (MMSE), Mini-Cog, Clock Drawing Test (CDT) and Ascertain Dementia 8 questionnaire (AD8) for older adults. 2015 participants aged 65 years or more in eastern China were enrolled. 4 screening tests were administered and scored by specifically trained psychiatrists. We used data from two-by-two tables to calculate the sensitivity, specificity, and positive and negative predictive values (PPV/NPV). Our study showed that dementia was highly prevalent among elderly in Zhejiang province. The Mini-Cog, with excellent screening characteristics and spending less time, could be considered to be used as a screening tool among communities to help to diagnose dementia early.

Orthodontic mini-implants are a potential source of metallic ions to the human body because of the corrosion of titanium (Ti) alloy in body fluids. The purpose of this study was to gauge the concentration of Ti, aluminum (Al), and vanadium (V), as a function of time, in the kidneys, livers, and lungs of rabbits that had Ti-6Al-4V alloy orthodontic mini-implants placed in their tibia. Twenty-three New Zealand rabbits were randomly divided into 4 groups: control, 1 week, 4 weeks, and 12 weeks. Four orthodontic mini-implants were placed in the left proximal tibia of 18 rabbits. Five control rabbits had no orthodontic mini-implants. After 1, 4, and 12 weeks, the rabbits were killed, and the selected tissues were extracted and prepared for analysis by graphite furnace atomic absorption spectrophotometry. Low amounts of Ti, Al, and V were detectable in the 1-week, 4-weeks, and 12-weeks groups, confirming that release of these metals from the mini-implants occurs, with diffusion and accumulation in remote organs. Despite the tendency of ion release when using the Ti alloy as orthodontic mini-implants, the amounts of metals detected were significantly below the average intake of these elements through food and drink and did not reach toxic concentrations.

Since 2001, a policy of positive mental health recovery has been promoted in the UK, with service user involvement. This has not been easy to implement in the clinical setting. To develop and validate a brief self-report, service user-designed, outcome measure (Mini-SeRvE), for clinical use, including spiritual and religious issues. From the previously developed Service user Recovery Evaluation scale (SeRvE), 15 questions were selected for Mini-SeRvE which was self-completed by 207 people; 100 service users and, for comparison, 107 staff. Results were analysed using SPSS software (SPSS Inc., Chicago, IL). Mini-SeRvE is reliable, Cronbach's alpha 0.852. Correlation with another recovery scale, Mental Health Recovery Measure, was high, r = 0.819. Three reliable subscales emerged; existential well-being (EWB), mental ill-being (MIB) and religious well-being (RWB). Scores of the EWB and MIB subscales were higher for staff, consistent with higher mental well-being. Religious well-being scores were higher in service users, who also rated religion as more important to them. Mini-SeRvE is a valid measure of service user recovery. The importance of religion/spiritual belief for our users is highlighted, this being reflected in the subject matter of Mini-SeRvE. Mini-SeRvE assessments could show individual priorities, evaluate therapy and aid clinical decision-making.

Full Text Available Cultural display in an open space or known as cultural parks appears rapidly as a worldwide phenomenon. From the European model which has a strong educational value, to the Asian parks which not only has educational function, but also has recreational purposes. So many types and characteristics of these parks, researches give them different names, thodse are Open-air museums, Ethnographic Theme Parks or even Theme Parks. Taman Mini Indonesia Indah as a part of this phenomenon was built first and foremost for educational purposes, therefore Taman Mini can be considered as an open-air museum. However, since Taman Mini also has recreational purposes, others can argue that Taman Mini is a theme park. Qualitative method will be used for this research, through observation to Taman Mini Indonesia Indah, followed by extensive literature review. With these data along with a table which points out the distinction between museum and theme parks. It can  be concluded that Taman Mini is a Theme Park.

Full Text Available Este artigo discutirá a creche como espaço de emancipação humana e de construção de epistemologias e experiências descolonizadoras. Pensar numa educação emancipatória desde o nascimento pressupõe-se desconstruir várias concepções que percorrem o imaginário e a práxis educativa das instituições brasileiras e que, por muito tempo, invisibilizaram as crianças pequenas e os bebês. É preciso colocar de ponta cabeça os modos de pensar as crianças pequenininhas e os espaços educativos. É necessário trazer as especificidades, as multiplicidades e as possibilidades desses sujeitos históricos e concretos que produzem culturas infantis e resistem a colonização, a opressão e a subordinação da sociedade adultocêntrica. Para isso, posicionamos nosso olhar na tensão das abordagens marxistas em direção as perspectivas pós-colonialistas a fim de antropofagicamente produzir inspirações teóricas e metodológicas para pensar as crianças, as infâncias e a educação infantil.

One of the challenges that we face in developing teaching materials or activities from research findings is testing the materials to determine that they work as intended. Traditionally faculty develop material for their own class, notice what worked and didn’t, and improve them the next year. However, as we move to a community process of creating and sharing teaching materials, a community-based process for testing materials is appropriate. The MARGINS project has piloted such a process for testing teaching materials and activities developed as part of its mini-lesson project (http://serc.carleton.edu/margins/index.html). Building on prior work developing mechanisms for community review of teaching resources (e.g. Kastens, 2002; Hancock and Manduca, 2005; Mayhew and Hall, 2007), the MARGINS evaluation team developed a structured classroom observation protocol. The goals of field testing are to a) gather structured, consistent feedback for the lesson authors based on classroom use; b) guide reviewers of these lessons to reflect on research-based educational practice as a framework for their comments; c) collect information on the data and observations that the reviewer used to underpin their review; d) determine which mini-lessons are ready to be made widely available on the website. The protocol guides faculty observations on why they used the activity, the effectiveness of the activity in their classroom, the success of the activity in leading to the desired learning, and what other faculty need to successfully use the activity. Available online (http://serc.carleton.edu/margins/protocol.html), the protocol can be downloaded and completed during instruction with the activity. In order to encourage review of mini-lessons using the protocol, a workshop focused on review and revision of activities was held in May 2009. In preparation for the workshop, 13 of the 28 participants chose to field test a mini-lesson prior to the workshop and reported that they found this

Full Text Available A sucessão empresarial é fundamental para as organizações familiares, pois muitas se extinguem em virtude dos problemas sucessórios, na transição entre a primeira e a terceira geração. Este artigo analisou o processo sucessório de cinco empresas familiares de pequeno e médio porte. Neste trabalho optou-se pela definição de Davel et al. (2000, que consideram empresa familiar quando a família detém a propriedade da empresa e tem voz ativa na gestão, os valores da família e da empresa se confundem e o processo sucessório é determinado pela família. Foi realizado um estudo comparativo de casos, de natureza qualitativa, cujos dados foram analisados com base na técnica de análise de conteúdo. Dentre os principais resultados encontrados destacam-se: a ausência de planejamento formal da sucessão e os sucedidos permanecem na empresa, mas demonstram consciência de que o poder é dos sucessores e pôde-se perceber a preponderância de uma articulação harmoniosa entre os interesses familiares e organizacionais. Os resultados sugerem que as PMEs conseguem passar pela sucessão sem maiores percalços e ainda aproveitar oportunidades de crescimento a partir da transição. Por outro lado, a ausência de preparação dos sucessores e de planejamento da sucessão pode ocasionar conflitos em relação à distribuição da herança e perdas financeiras. O artigo contribui para demonstrar que as dificuldades no processo sucessório podem representar, no caso de PME´s, oportunidades de aprendizado e crescimento organizacional, reestruturação de processos e inovações que aumentem a competitividade da empresa.

A mini-microscope was developed for in situ monitoring of cells by modifying off-the-shelf components of a commercial webcam. The mini-microscope consists of a CMOS imaging module, a small plastic lens and a white LED illumination source. The CMOS imaging module was connected to a laptop computer through a USB port for image acquisition and analysis. Due to its compact size, 8 × 10 × 9 cm, the present microscope is portable and can easily fit inside a conventional incubator, and enables real-time monitoring of cellular behaviour. Moreover, the mini-microscope can be used for imaging cells in conventional cell culture flasks, such as Petri dishes and multi-well plates. To demonstrate the operation of the mini-microscope, we monitored the cellular migration of mouse 3T3 fibroblasts in a scratch assay in medium containing three different concentrations of fetal bovine serum (5, 10, and 20%) and demonstrated differential responses depending on serum levels. In addition, we seeded embryonic stem cells inside poly(ethylene glycol) microwells and monitored the formation of stem cell aggregates in real time using the mini-microscope. Furthermore, we also combined a lab-on-a-chip microfluidic device for microdroplet generation and analysis with the mini-microscope and observed the formation of droplets under different flow conditions. Given its cost effectiveness, robust imaging and portability, the presented platform may be useful for a range of applications for real-time cellular imaging using lab-on-a-chip devices at low cost.

The purpose of this systematic review was to evaluate the use of mini implants to retain complete overdentures in terms of survival rates of mini implants, marginal bone loss, satisfaction, and quality of life. This report followed the PRISMA Statement and PICO question. This review has been registered at PROSPERO under the number CRD42016036141. Two independent reviewers performed a comprehensive search of studies published until September 2016 and listed in the PubMed/MEDLINE, Embase, and The Cochrane Library databases. The focused question was: is the use of mini implants feasible for prosthodontic rehabilitation with complete overdentures? The 24 studies selected for review evaluated 1273 patients whose mean age was 65.93 years; these patients had received 2494 mini implants and 386 standard implants for retaining overdenture prosthesis. The mean follow-up time was 2.48 years (range: 1-7 years). There was a higher survival rate of mini implants (92.32%). More frequent failures for maxillary (31.71%) compared with mandibular arches (4.89%). The majority of studies revealed marginal bone loss values similar to those of standard implants (overdenture prosthesis is considered an alternative treatment when standard treatment is not possible, since it presents high survival rates, acceptable marginal bone loss, and improvements in variables related to satisfaction and quality of life. Based on the results of this study, the use of a minimum 4 and 6 mini implants can be considered a satisfactory treatment option for rehabilitation of the mandibular and maxillary arches respectively with a complete overdenture.

The aim of this study was to compare the screening value of the Mini-Cog, Clock Drawing Test (CDT), Mini-Mental State Examination (MMSE) and the algorithm MMSE and/or CDT to separate elderly people with dementia from healthy depending on test time, type and severity of dementia, and demographic variables in a German Memory Clinic. Data from a heterogeneous patient sample and healthy participants (n = 502) were retrospectively analyzed. Of the 438 patients with dementia, 49.1% of the dementia diagnoses were Alzheimer's dementia and 50.9% were non-Alzheimer's dementia. Sixty-four participants were classified as cognitively unimpaired. The CDT and an extraction of the 3-item recall of the MMSE were used to constitute the Mini-Cog algorithm. Overall, the Mini-Cog showed significantly higher discriminatory power (86.8%) than the MMSE (72.6% at a cut-off ≤ 24 and 79.2% at ≤ 25, respectively) and CDT (78.1%) (each p 0.05). The specificity of the Mini-Cog (100.0%) was similar to that of the MMSE (100.0% for both cut-offs) and CDT (96.9%) (p = 0.154). For all age and educational groups the Mini-Cog outmatched the CDT and MMSE, and was less affected by education than MMSE and less susceptible for the dementia stage than the CDT. The Mini-Cog proved to have superior discriminatory power than either CDT or MMSE and is demonstrated to be a valid "short" screening instrument taking 3 to 4 minutes to administer in the geriatric setting.

Observations of the temperature anisotropies induced as light from the CMB passes through large scale structures in the late universe are a sensitive probe of the interactions of photons in such environments. In extensions of the Standard Model which give rise to mini-charged particles, photons propagating through transverse magnetic fields can be lost to pair production of such particles. Such a decrement in the photon flux would occur as photons from the CMB traverse the magnetic fields of galaxy clusters. Therefore late time CMB anisotropies can be used to constrain the properties of mini- charged particles. We outline how this test is constructed, and present new constraints on mini-charged particles from observations of the Sunyaev-Zel'dovich effect in the Coma cluster. (orig.)

Dementia is one of the leading causes of dependence in the elderly. This study was conducted to estimate diagnostic performance of dementia screening tests including Mini-Mental State Examination (MMSE), Mini-Cog, Clock Drawing Test (CDT) and Ascertain Dementia 8 questionnaire (AD8) by Bayesian models. A total of 2015 participants aged 65 years or more in eastern China were enrolled. The four screening tests were administered and scored by specifically trained psychiatrists. The prior information of sensitivity and specificity of every screening test was updated via Bayes' theorem to a posterior distribution. Then the results were compared with the estimation based on National Institute of Aging-Alzheimer's Association criteria (NIA-AA). The diagnostic characteristics of Mini-Cog, including sensitivity, specificity, PPV, NPV, especially the Youden index, performed well, even better than the combinations of several screening tests. The Mini-Cog with excellent screening characteristics, spending less time, could be considered to be used as a screening test to help to screen patients with cognitive impairment or dementia early. And Bayesian method was shown to be a suitable tool for evaluating dementia screening tests.

Full Text Available The lack of access to electricity of more than 1.1 billion people around the world remains a major developmental challenge and Goal 7 of the Sustainable Development Goals (SDG as well as Sustainable Energy for All (SE4ALL have set a target of universal electrification by 2030. Various studies have identified mini-grid-based electrification as a possible solution. There is a growing body of literature available now that has explored the feasibility, practical application and policy interventions required to support mini-grids. Through a review of available literature, this paper explores whether mini-grids can be a solution for the base of the pyramid (BoP market and the challenges faced in deploying mini-grids in such markets. Interventions to support the mini-grid deployment are also discussed. The paper finds that the mini-grids are targeting the BoP market but the business is not attractive in profitability terms and requires financial support. Lack of regulatory clarity and non-coordinated policies affect the financial viability of projects, which requires careful support. Mini-grid electrification has hardly been embedded in rural development agenda and hence they have not contributed significantly to livelihood generation. Careful realignment of policies, regulatory frameworks and support systems can better support mini-grid deployment in developing countries.

This study was aimed at developing risperidone oral disintegrating mini-tablets (OD-mini-tablets) as age-appropriate formulations and to assess their suitability for infants and pediatric use. An experimental Box-Behnken design was applied to assure high quality of the OD-mini-tablets and reduce product variability. The design was employed to understand the influence of the critical excipient combinations on the production of OD-mini-tablets and thus guarantee the feasibility of obtaining products with dosage form uniformity. The variables selected were mannitol percent in Avicel (X1), swelling pressure of the superdisintegrant (X2), and the surface area of Aerosil as a glidant (X3). Risperidone-excipient compatibilities were investigated using FTIR and the spectra did not display any interaction. Fifteen formulations were prepared and evaluated for pre- and post-compression characteristics. The prepared OD-mini-tablet batches were also assessed for disintegration in simulated salivary fluid (SSF, pH 6.2) and in reconstituted skimmed milk. The optimized formula fulfilled the requirements for crushing strength of 5 kN with minimal friability, disintegration times of 8.4 and 53.7 s in SSF and skimmed milk, respectively. This study therefore proposes the risperidone OD-mini-tablet formula having robust mechanical properties, uniform and precise dosing of medication with short disintegration time suitable for pediatric use.

Full Text Available This case report outlines the possibility of accelerated tooth movement with the combination of microosteoperforation and mini-screws. A 14-year-old male patient presented Class II malocclusion with maxillary incisor protrusion. Upper first premolars were extracted, and after leveling, accelerated canine distalization started. For pre- and postdistalization times, amount of distalization, periodontal health, and root resorption were assessed. Within the limitations of this case report, micro-osteoperforations with mini-screw have a potential for shortening the treatment time.

The Mini-Mental State Examination is a widely used cognitive screening measure. The purpose of the present study was to assess how 5 specific clusters of Mini-Mental State Examination items (ie, subscores) correlate with and predict specific areas of daily functioning in dementia patients, 61 patients with varied forms of dementia were administered the Mini-Mental State Examination and an observation-based daily functional test (the Direct Assessment of Functional Status). The results revealed that the orientation and attention subscores of the Mini-Mental State Examination correlated most significantly with most functional domains. The Mini-Mental State Examination language items correlated with all but the shopping and time orientation tasks, while the Mini-Mental State Examination recall items correlated with the Direct Assessment of Functional Status time orientation and shopping tasks. Stepwise regression analyses found that among the Mini-Mental State Examination subscores, orientation was the single, best independent predictor of daily functioning.

To promote clinical application of the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) system a shorter version (the mini-SCAN) was devised. Its psychometric properties were unknown. To establish the validity and practical properties of the mini-SCAN. One hundred and six participants were interviewed twice, once with the SCAN and once with the mini-SCAN. The level of agreement was established for the categories: no disorder, affective disorders, anxiety disorders, non-affective psychotic disorders, affective psychotic disorders. The mini-SCAN is a valid instrument. Most kappa values were around 0.90. Only for the class of affective psychotic disorders was the agreement moderate. Mean duration of the mini-SCAN interviews was 25 min shorter than the SCAN interviews. Participants and interviewers were generally satisfied with the interview format and questions. The mini-SCAN can be used as a diagnostic instrument for clinical purposes and for clinical studies when the present episode is the focus of attention.

The use of mini-implants have made a major contribution to orthodontic treatment. Demand has aroused scientific curiosity about implant placement procedures and techniques. However, the reasons for instability have not yet been made totally clear. The aim of this article is to establish a relationship between implant placement technique and mini-implant success rates by means of examining the following hypotheses: 1) Sites of poor alveolar bone and little space between roots lead to inadequate implant placement; 2) Different sites require mini-implants of different sizes! Implant size should respect alveolar bone diameter; 3) Properly determining mini-implant placement site provides ease for implant placement and contributes to stability; 4) The more precise the lancing procedures, the better the implant placement technique; 5) Self-drilling does not mean higher pressures; 6) Knowing where implant placement should end decreases the risk of complications and mini-implant loss.

This study evaluates the influence of different implant materials on the primary stability of orthodontic mini-implants by measuring the resonance frequency. Twenty-five orthodontic mini-implants with a diameter of 2 mm were used. The first group contained stainless steel mini-implants with two different lengths (10 and 12 mm). The second group included titanium alloy mini-implants with two different lengths (10 and 12 mm) and stainless steel mini-implants 10 mm in length. The mini-implants were inserted into artificial bones with a 2-mm-thick cortical layer and 40 or 20 lb/ft(3) trabecular bone density at insertion depths of 2, 4, and 6 mm. The resonance frequency of the mini-implants in the artificial bone was detected with the Implomates(®) device. Data were analyzed by two-way analysis of variance followed by the Tukey honestly significant difference test (α = 0.05). Greater insertion depth resulted in higher resonance frequency, whereas longer mini-implants showed lower resonance frequency values. However, resonance frequency was not influenced by the implant materials titanium alloy or stainless steel. Therefore, the primary stability of a mini-implant is influenced by insertion depth and not by implant material. Insertion depth is extremely important for primary implant stability and is critical for treatment success. Copyright © 2012. Published by Elsevier B.V.

In August 1993 the first German `Delphi Report on Developments in Science and Technology` was published. It was elaborated by the Fraunhofer Institute for System Engineering and Innovation Research (FhG-ISI) in cooperation with the Japanese National Institute of Science and Technology Policy (NISTEP). The `MINI-DELPHI` now completed by FhG-ISI, again in cooperation with NISTEP, is a further development of the Delphi approach in that it is more differentiated in its questions and assessment criteria than its predecessors. `MINI-DELPHI` is not intended as a comprehensive forecast on technology in general but rather focusses on key topics. Its emphasis is on technology demand and the relevance of technologies to social issues. Although the Mini-Delphi study was primarily aimed at further refining the methodology employed, it nevertheless contains a wealth of information and details on circumscript questions. The requisite database is provided by tables on the results of two inquiry rounds among Japanese and German experts.

Escobedo G, C. R.; Vega C, H. R.; Davila H, V. M.

2015-10-01

In this work the design of a mini subcritical nuclear reactor formed by means of light water moderator, uranium as fuel, and isotopic neutron source of 239 PuBe was carried out. The design was done by Monte Carlo methods with the code MCNP5 in which uranium was modeled in an array of concentric holes cylinders of 8.5, 14.5, 20.5, 26.5, 32.5 cm of internal radius and 3 cm of thickness, 36 cm of height. Different models were made from a single fuel cylinder (natural uranium) to five. The neutron source of 239 PuBe was situated in the center of the mini reactor; in each arrangement was used water as moderator. Cross sections libraries Endf/Vi were used and the number of stories was large enough to ensure less uncertainty than 3%. For each case the effective multiplication factor k e -f f , the amplification factor and the power was calculated. Outside the mini reactor the ambient dose equivalent H (10) was calculated for different cases. The value of k eff , the amplification factor and power are directly related to the number of cylinders of uranium as fuel. Although the average energy of the neutrons 239 PuBe is between 4.5 and 5 MeV in the case of the mini reactor for a cylinder, in the neutron spectrum the presence of thermal neutrons does not exist, so that produced fissions are generated with fast neutrons, and in designs of two and three rings the neutron spectra shows the presence of thermal neutrons, however the fissions are being generated with fast neutrons. Finally in the four and five cases the amount of moderator is enough to thermalized the neutrons and thereby produce the fission. The maximum value for k eff was 0.82; this value is very close to the assembly of Universidad Autonoma de Zacatecas generating a k eff of 0.86. According to the safety and radiation protection standards for the design of mini reactor of one, two and three cylinders they comply with the established safety, while designs of four and five cylinders not met.

1994-07-15

Nematocysts (cnidocysts) are exocytotic organelles found in all cnidarians. Here, atomic force microscopy and field emission scanning electron microscopy reveal the structure of the nematocyst capsule wall. The outer wall consists of globular proteins of unknown function. The inner wall consists of bundles of collagen-like fibrils having a spacing of 50 to 100 nanometers and cross-striations at intervals of 32 nanometers. The fibrils consist of polymers of "mini-collagens," which are abundant in the nematocysts of Hydra. The distinct pattern of mini-collagen fibers in the inner wall can provide the tensile strength necessary to withstand the high osmotic pressure (15 megapascals) in the capsules.

Concerning production and decay of mini black holes

CERN Document Server

Hajdukovic, D

2007-01-01

In the next few years, theories predicting possibility to create mini black holes will be tested at CERN. Either experimental verification or rejection of these theories is of great scientific importance. There is a large consensus that, if successfully created, these short living mini black holes will decay through thermal (Hawking's) radiation. In the present comment we point out, that under assumption of the gravitational repulsion between matter and antimatter (in short we call it antigravity), thermal radiation may be dominated by a non-thermal radiation (being the consequence of pair creation from the vacuum, by gravitational field, which in the case of antigravity, pushes particles and antiparticles in opposite directions). Thus, the eventual creation of mini black holes may turn to be an unexpected opportunity to test the existence of antigravity.

When mini-implants fail during orthodontic treatment, there is a need to have a backup plan to either replace the failed implant in the adjacent interradicular area or wait for the bone to heal before replacing the mini-implant. We propose a novel way to overcome this problem by replacement with a miniplate so as not to interrupt treatment or prolong treatment time. The indications, advantages, efficacy, and procedures for switching from a mini-implant to a miniplate are discussed. Two patients who required replacement of failed mini-implants are presented. In the first patient, because of the proximity of the buccal vestibule to the mini-implant, it was decided to replace the failed mini-implant by an I-shaped C-tube miniplate. In the second patient, radiolucencies were found around the failed mini-implants, making the adjacent alveolar bone unavailable for immediate placement of another mini-implant. In addition, the maxillary sinus pneumatization was expanded deeply into the interradicular spaces; this further mandated an alternative placement site. One failed mini-implant was examined under a scanning electron microscope for bone attachment. Treatment was completed in both patients after replacement with miniplates without interrupting the treatment mechanics or prolonging the treatments. Examination under the scanning electron microscope showed partial bone growth into the coating pores and titanium substrate interface even after thorough cleaning and sterilization. Replacement with a miniplate is a viable solution for failed mini-implants during orthodontic treatment. The results from microscopic evaluation of the failed mini-implant suggest that stringent guidelines are needed for recycling used mini-implants.

Evaluation of mini super computers for nuclear design applications

International Nuclear Information System (INIS)

Altomare, S.; Baradari, F.

1987-01-01

The evolution of the mini super computers will force changes from the current environment of performing nuclear design calculations on mainframe computers (such as a CRAY) to mini super computers. This change will come about for a number of reasons. First, the mini super computers currently available in the marketplace offer the power and speed comparable to mainframes and can provide the capability to support highly computer intensive calculations. Second, the equipment is physically smaller and can easily be installed and operated without extensive investments in facilities and operations support. Third, the computer capacity can be acquired with as much needed memory, disk, and tape capacity as may be needed. Another reasons is that the performance/cost ratio has increased drastically as hardware costs have decreased. A study was conducted at the Westinghouse Commercial Nuclear Fuel Division (CNFD) to evaluate the mini super computers for use in nuclear core design. As a result of this evaluation, Westinghouse CNFD is offering a combined hardware/software technology transfer package for core design. This package provides the utility designer with a totally dedicated mini super computer comparable in speed to the CRAY 1S with sufficient capacity for a sizable design group to perform the engineering activities related to nuclear core design and operations support. This also assures the utility of being totally compatible with the CNFD design codes, thus assuring total update compatibility

Full Text Available Segundo o Sebrae (2013, a taxa de sobrevivência das Micro e Pequenas Empresas (MPE no Brasil vem melhorando, com sobrevivência de 75,6% nos primeiros dois anos de vida. Das sobreviventes, muitas enfrentam dificuldades no mercado, tendo que por vezes optar para o uso de práticas ilícitas ou antiéticas e ainda não se considerando “fora da lei”. Nesse contexto, o objetivo geral é relacionar o uso das práticas ilegais ou antiéticas utilizadas pelas MPE para sobreviverem com a percepção de ilicitude dessas práticas. Esta pesquisa é do tipo descritiva e quantitativa. Após levantamento bibliográfico e pesquisa exploratória com 17 MPE foi realizada uma pesquisa de campo com 102 MPE, com a aplicação de um questionário com 33 variáveis de práticas ilegais ou antiéticas, onde as práticas deveriam ser avaliadas pelo respondente com base no comportamento observado de seus concorrentes, por meio de uma escala Likert, de cinco pontos. Pode-se concluir que todas as práticas investigadas estão sendo utilizadas em algum grau pelos empreendedores, cabendo destacar que para apenas quatro das 33 práticas a percepção de ilicitude se apresentou menor que a de licitude, evidenciando que a maioria (29 de 33 práticas vem sendo utilizada mesmo tendo-se a consciência de que são ilícitas. Pode-se concluir também que das nove práticas destacadas, cinco delas referem-se à evasão fiscal. Percebeu-se que as práticas que ferem diretamente o interesse do consumidor não são vistas como “ilícitas” pelos empreendedores.

Context: Mini-basketball is one of the most popular junior sports in Japan. Mini-basketball–related injuries may increase because of early specialization. However, no reports have been published to date concerning basketball injuries in children younger than 12 years of age. Objective: To prospectively study the incidence, sites, types, and mechanisms of injuries in mini-basketball teams. Design: Descriptive epidemiology study. Setting: Mini-basketball teams in Kobe, Japan. Patients or Other Participants: A total of 95 players in 7 community-based mini-basketball club teams (age range, 9 through 12 years). Main Outcome Measure(s): Data on all practice and game injuries for the 2013–2014 season were collected using an injury report form. Injury rates were calculated according to site, type, and mechanism. Results: The overall injury rate was 3.83 per 1000 athlete-hours (AHs). The game injury rate (12.92/1000 AHs) was higher than the practice injury rate (3.13/1000 AHs; P basketball players. The high practice injury rate in this study may be due to specific factors related to growth, such as individual differences in height, or to skills, such as inexperience in ball handling.

2014-12-01

The aim of this study was to understand whether the pitch relationship between micro and macro thread designs with a parametrical relationship in a dual-thread mini-implant can improve primary stability. Three types of mini-implants consisting of single-thread (ST) (0.75 mm pitch in whole length), dual-thread A (DTA) with double-start 0.375 mm pitch, and dual-thread B (DTB) with single-start 0.2 mm pitch in upper 2-mm micro thread region for performing insertion and pull-out testing. Histomorphometric analysis was performed in these specimens in evaluating peri-implant bone defects using a non-contact vision measuring system. The maximum inserted torque (Tmax) in type DTA was found to be the smallest significantly, but corresponding values found no significant difference between ST and DTB. The largest pull-out strength (Fmax) in the DTA mini-implant was found significantly greater than that for the ST mini-implant regardless of implant insertion orientation. Mini-implant engaged the cortical bone well as observed in ST and DTA types. Dual-thread mini-implant with correct micro thread pitch (parametrical relationship with macro thread pitch) in the cortical bone region can improve primary stability and enhanced mechanical retention.

This paper evaluates the benefits of developing the mini-generation PV market in Portugal. It presents the legal framework and current status of the Portuguese PV electricity sector, and compares the country to other European nations: France, Germany, Greece, Italy, Spain and the United Kingdom. A model that combines PVGIS with a self-developed financial tool is used to assess the feasibility of a 150 kW mini-generation system using five different technologies: fixed mount, single-axis tracking, double-axis tracking, low concentration and medium concentration (MCPV). The profitability of the mini-generation systems in the seven countries studied is calculated and compared. According to this analysis, MCPV and, of the conventional technologies, the single-axis tracking systems are the most profitable technologies. Despite the attractiveness of the current Portuguese feed-in tariffs and of the abundant solar resource, investors are discouraged and the country's PV market is far from mature. Specific mini-generation regulations should focus on a fast and transparent licensing procedure and should promote the access to financing. This would attract new investments, which would result in the growth of the PV electricity produced, and would help Portugal to meet its European Union Renewable Energy targets. - Highlights: → This work promotes the development of a mini-generation PV market in Portugal. → The Portuguese current status and legal framework is compared to other EU countries. → The profitability of 5 different PV technologies is compared for 7 European countries. → The Portuguese growth potential for PV energy is still big. → Portugal, due to its radiation levels, presents excellent investment opportunities.

Full Text Available Evaluating food intake quality may contribute to the development of nutrition programs. In Mexico, there are no screening tools that can be administered quickly for the evaluation of this variable. The aim was to determine the reproducibility of a mini-survey designed to evaluate the quality of food intake (Mini-ECCA in a Mexican population. Mini-ECCA consists of 12 questions that are based on Mexican and international recommendations for food and non-alcoholic beverage intake, with the support of photographs for food quantity estimation. Each question scores as 0 (unhealthy or 1 (healthy, and the final score undergoes a classification procedure. Through the framework of a nutritional study, 152 employees of the municipal water company in Guadalajara, Mexico (April–August 2016, were invited to participate. The survey was administered in two rounds (test and retest with a 15-day interval between them. We calculated the Spearman correlation coefficient, the intra-class correlation coefficient (ICC, and weighted kappa for score classification agreement (SPSS versus 14 p < 0.05 was considered statistically significant. The survey obtained a “good” reproducibility (ρ = 0.713, p < 0.001, and an excellent concordance (ICC = 0.841 Confidence Interval 95% 0.779, 0.885. It can thus be said that the Mini-ECCA displayed acceptable reproducibility and is suitable for the purpose of dietary assessment and guidance.

2013-03-01

Mini implants are commonly used in orthodontics and for interim prosthodontic treatment, but evidence for their use in definitive prosthodontic treatment is not clear. This systematic review evaluated the mini-implant literature to analyze short-term (1 to 5 years), medium-term (5 to 10 years), and long-term (beyond 10 years) survival rates when used for definitive prosthodontic treatment. An electronic search of the English language literature for articles published between January 1974 and May 2012 was performed by using PubMed and Cochrane databases with predetermined inclusion criteria. Key terms included in the search were mini dental implants, narrow diameter implants, reduced diameter implants, small diameter implants, transitional implants, interim implants, and provisional implants. After a systematic filtering process, the selected articles were subjected to a detailed review, and the data collected were used to calculate the 1-year interval survival rate (ISR) and the cumulative survival rate (CSR). The electronic database search yielded 1807 titles. By scrutinizing the titles and abstracts with inclusion and exclusion criteria, the researchers identified 9 studies of mini implants for definitive prosthodontic treatment. Of the studies identified, 1 was a randomized controlled trial, 2 were prospective studies, and 6 were retrospective studies. The majority of mini implants were placed by using a flapless surgical technique in the mandibular anterior region to support an overdenture. The 1st year ISR was 94.7% and the CSR over a 9-year period, primarily attributed to data from 1 study, was 92.2%. Most implants were immediately loaded and almost all implant failures occurred during the first year after implant placement. For short-term survival, the first year ISR of 94.7% of mini dental implants appears encouraging, but the true 1-year survival rate is unknown, as the minimum follow-up period reported for several implants was less than a year

Mini-Sniffer III on Lakebed with Ground Support Crew

The third version of the Mini-Sniffer remotely-piloted research vehicle on Rogers Dry Lake, adjacent to NASA's Dryden Flight Research Center, Edwards, California. The futuristic-looking ground crew are in white, self-contained suits, because the engine on this third version of the Mini-Sniffer was powered by hydrazine, which is a very hazardous material. The Mini-Sniffer was a remotely controlled, propeller-driven vehicle developed at the NASA Flight Research Center (which became the Dryden Flight Research Center, Edwards, California, in 1976) as a potential platform to sample the upper atmosphere for pollution. The vehicle, flown from 1975 to 1977, was one of the earliest attempts by NASA to develop an aircraft that could sense turbulence and measure natural and human-produced atmospheric pollutants at altitudes above 80,000 feet with a variable-load propeller that was never flight-tested. Three Mini-Sniffer vehicles were built. The number 1 Mini-Sniffer vehicle had swept wings with a span of 18 feet and canards on the nose. It flew 12 flights with the gas-powered engine at low altitudes of around 2,500 feet. The number 1 vehicle was then modified into version number 2 by removing the canards and wing rudders and adding wing tips and tail booms. Twenty flights were made with this version, up to altitudes of 20,000 feet. The number 3 vehicle had a longer fuselage, was lighter in weight, and was powered by the non-air-breathing hydrazine engine designed by NASA's Johnson Space Center in Houston, Texas. This version was designed to fly a 25-pound payload to an altitude of 70,000 feet for one hour or to climb to 90,000 feet and glide back. The number 3 Mini-Sniffer made one flight to 20,000 feet and was not flown again because of a hydrazine leak problem. All three versions used a pusher propeller to free the nose area for an atmospheric-sampling payload. At various times the Mini-Sniffer has been considered for exploration in the carbon dioxide atmosphere of the

Neutrino-nucleus neutral current elastic interactions measurement in MiniBooNE

Science.gov (United States)

Perevalov, Denis

The MiniBooNE experiment at the Fermi National Accelerator Laboratory (Fermilab) was designed to search for numu → nu e neutrino oscillations at Deltam 2 ˜ 1 eV2 using an intense neutrino flux with an average energy Enu ˜ 700 MeV. From 2002 to 2009 MiniBooNE has accumulated more than 1.0x1021 protons on target (POT) in both neutrino and antineutrino modes. MiniBooNE provides a perfect platform for detailed measurements of exclusive and semi-inclusive neutrino cross-sections, for which MiniBooNE has the largest samples of events up to date, such as neutral current elastic (NCE), neutral current pi 0, charged current quasi-elastic (CCQE), charged current pi +, and other channels. These measured cross-sections, in turn, allow to improve the knowledge of nucleon structure. This thesis is devoted to the study of NCE interactions. Neutrino-nucleus neutral current elastic scattering (nuN → nu N) accounts for about 18% of all neutrino interactions in MiniBooNE. Using a high-statistics, high purity sample of NCE interactions in MiniBooNE, the flux-averaged NCE differential cross-section has been measured and is being reported here. Further study of the NCE cross-section allowed for probing the structure of nuclei. The main interest in the NCE cross-section is that it may be sensitive to the strange quark contribution to the nucleon spin, Deltas, this however requires a separation of NCE proton (nup → nu p) from NCE neutron (nun → nun ) events, which in general is a challenging task. MiniBooNE uses a Cherenkov detector, which imposes restrictions on the measured nucleon kinematic variables, mainly due to the impossibility to reconstruct the nucleon direction below the Cherenkov threshold. However, at kinetic energies above this threshold MiniBooNE is able to identify NCE proton events that do not experience final state interactions (FSI). These events were used for the Deltas measurement. In this thesis MiniBooNE reports the NCE (n+p) cross-section, the measurement

Recommended safety objectives, principles and requirements for mini-reactors

International Nuclear Information System (INIS)

1991-05-01

Canadian and international publications containing objectives, principles and requirements for the safety of nuclear facilities in general and nuclear power plants in particular have been reviewed for their relevance to mini-reactors. Most of the individual recommendations, sometimes with minor wording changes, are applicable to mini-reactors. However, some prescriptive requirements for the shutdown, emergency core cooling and containment systems of power reactors are considered inappropriate for mini-reactors. The Advisory Committee on Nuclear Safety favours a generally non-prescriptive approach whereby the applicant for a mini-reactor license is free to propose any means of satisfying the fundamental objectives, but must convince the regulatory agency to that effect. To do so, a probabilistic safety assessment (PSA) would be the favoured procedure. A generic PSA for all mini-reactors of the same design would be acceptable. Notwithstanding this non-prescriptive approach, the ACNS considers that it would be prudent to require the existence of at least one independent shutdown system and two physically independent locations from which the reactor can be shut down and the shutdown condition monitored, and to require provision for an assumed loss of integrity of the primary cooling system's boundary unless convincing arguments to the contrary are presented. The ACNS endorses in general the objectives and fundamental principles proposed by the interorganizational Small Reactor Criteria working group, and intends to review and comment on the documents on specific applications to be issued by that working group

1990-10-01

Split ejaculates from four boars were frozen with a programmable freezing machine, in mini- (0.25 ml) and maxi- (5 ml) plastic straws with an extender at either acidic (6.3) or alkaline (7.4) pH. Glycerol (3%) was used as cryoprotectant. The freezing of the semen was monitored by way of thermocouples placed in the straws. Post-thaw motility and acrosome integrity were evaluated; the latter using phase contrast microscopy, eosin-nigrosin stain and electron microscopy. Post-thaw sperm motility was significantly higher when semen was frozen in mini-straws than in maxi-straws. For the mini-straws, the motility was better when semen was exposed to an acidic environment during freezing, but this beneficial effect of the low extracellular pH was not evident when maxi-straws were thawed. The motility of the spermatozoa diminished significantly during the thermoresistance test (0 h and 2 h time) at 37 degrees C in a similar way for both straws and extracellular pH's. The freezing procedure, no matter the extracellular pH, did not cause major acrosomal damages, but significantly more normal apical ridges were present in the mini-straws than in the maxi-straws. This in vitro evaluation indicated that the freezing method employed was better for mini- than for maxi-straws since the freezing of the 5 ml volumes was not homogeneous, due to the large section area between the surface and the core of the straw.

A mini-microscope was developed for in situ monitoring of cells by modifying off-the-shelf components of a commercial webcam. The mini-microscope consists of a CMOS imaging module, a small plastic lens and a white LED illumination source. The CMOS imaging module was connected to a laptop computer through a USB port for image acquisition and analysis. Due to its compact size, 8 × 10 × 9 cm, the present microscope is portable and can easily fit inside a conventional incubator, and enables real-time monitoring of cellular behaviour. Moreover, the mini-microscope can be used for imaging cells in conventional cell culture flasks, such as Petri dishes and multi-well plates. To demonstrate the operation of the mini-microscope, we monitored the cellular migration of mouse 3T3 fibroblasts in a scratch assay in medium containing three different concentrations of fetal bovine serum (5, 10, and 20%) and demonstrated differential responses depending on serum levels. In addition, we seeded embryonic stem cells inside poly(ethylene glycol) microwells and monitored the formation of stem cell aggregates in real time using the mini-microscope. Furthermore, we also combined a lab-on-a-chip microfluidic device for microdroplet generation and analysis with the mini-microscope and observed the formation of droplets under different flow conditions. Given its cost effectiveness, robust imaging and portability, the presented platform may be useful for a range of applications for real-time cellular imaging using lab-on-a-chip devices at low cost.

Species substitution is a form of seafood fraud for the purpose of economic gain. DNA barcoding utilizes species-specific DNA sequence information for specimen identification. Previous work has established the usability of short DNA sequences-mini-barcodes-for identification of specimens harboring degraded DNA. This study aims at establishing a DNA mini-barcoding system for all fish species commonly used in processed fish products in North America. Six mini-barcode primer pairs targeting short (127-314 bp) fragments of the cytochrome c oxidase I (CO1) DNA barcode region were developed by examining over 8,000 DNA barcodes from species in the U.S. Food and Drug Administration (FDA) Seafood List. The mini-barcode primer pairs were then tested against 44 processed fish products representing a range of species and product types. Of the 44 products, 41 (93.2%) could be identified at the species or genus level. The greatest mini-barcoding success rate found with an individual primer pair was 88.6% compared to 20.5% success rate achieved by the full-length DNA barcode primers. Overall, this study presents a mini-barcoding system that can be used to identify a wide range of fish species in commercial products and may be utilized in high throughput DNA sequencing for authentication of heavily processed fish products.

The mini-clinical evaluation exercise (mini-CEX) is widely used in the UK to assess clinical competence, but there is little evidence regarding its implementation in the undergraduate setting. This study aimed to estimate the validity and reliability of the undergraduate mini-CEX and discuss the challenges involved in its implementation. A total of 3499 mini-CEX forms were completed. Validity was assessed by estimating associations between mini-CEX score and a number of external variables, examining the internal structure of the instrument, checking competency domain response rates and profiles against expectations, and by qualitative evaluation of stakeholder interviews. Reliability was evaluated by overall reliability coefficient (R), estimation of the standard error of measurement (SEM), and from stakeholders' perceptions. Variance component analysis examined the contribution of relevant factors to students' scores. Validity was threatened by various confounding variables, including: examiner status; case complexity; attachment specialty; patient gender, and case focus. Factor analysis suggested that competency domains reflect a single latent variable. Maximum reliability can be achieved by aggregating scores over 15 encounters (R = 0.73; 95% confidence interval [CI] +/- 0.28 based on a 6-point assessment scale). Examiner stringency contributed 29% of score variation and student attachment aptitude 13%. Stakeholder interviews revealed staff development needs but the majority perceived the mini-CEX as more reliable and valid than the previous long case. The mini-CEX has good overall utility for assessing aspects of the clinical encounter in an undergraduate setting. Strengths include fidelity, wide sampling, perceived validity, and formative observation and feedback. Reliability is limited by variable examiner stringency, and validity by confounding variables, but these should be viewed within the context of overall assessment strategies.

Compact, cost-effective and high-performance microscope that enables the real-time imaging of cells and lab-on-a-chip devices is highly demanded for cell biology and biomedical engineering. This paper aims to present the design and application of an inexpensive wireless mini-microscope with resolution up to 2592 × 1944 pixels and speed up to 90 fps. The mini-microscope system was built on a commercial embedded system (Raspberry Pi). We modified a camera module and adopted an inverse dual lens system to obtain the clear field of view and appropriate magnification for tens of micrometer objects. The system was capable of capturing time-lapse images and transferring image data wirelessly. The entire system can be operated wirelessly and cordlessly in a conventional cell culturing incubator. The developed mini-microscope was used to monitor the attachment and proliferation of NIH-3T3 and HEK 293 cells inside an incubator for 50 hours. In addition, the mini-microscope was used to monitor a droplet generation process in a microfluidic device. The high-quality images captured by the mini-microscope enabled us an automated analysis of experimental parameters. The successful applications prove the great potential of the developed mini-microscope for monitoring various biological samples and microfluidic devices. This paper presents the design of a high resolution mini-microscope system that enables the wireless real-time imaging of cells inside the incubator. This system has been verified to be a useful tool to obtain high-quality images and videos for the automated quantitative analysis of biological samples and lab-on-a-chip devices in the long term.

The Mini-Sniffer is a small unmanned survey aircraft developed by NASA to conduct turbulence and atmospheric pollution measurements from ground level to an altitude of 90,000 ft. Carrying a 25-lb air sampling apparatus, the Mini-Sniffer typically cruises for one hour at 70,000 ft before being remotely piloted back to earth. A hydrazine monopropellant engine powers the craft, while a PCM telemetering system and a radar transponder provide control functions. Development of a high-performance low-Reynolds-number airfoil could make the research craft suitable for a low-altitude terrain-following mission on Mars.

Onset of social phobia (SP) typically occurs in adolescence. Short screening instruments for its assessment are needed for use in primary health and school settings. The 3-item Mini-Social Phobia Inventory (SPIN) has demonstrated effectiveness in screening for generalized SP (GSP) in adults. This study examined the psychometrics of the Mini-SPIN in an adolescent general population sample. Three hundred fifty adolescents aged 12 to 17 years were clinically interviewed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version for identification of SP and other Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis I disorders, blind to their Mini-SPIN status. Associations between SP; subclinical SP; other anxiety, depressive, and disruptive disorders; and Mini-SPIN scores were examined, and diagnostic efficiency statistics were calculated. The association between Mini-SPIN scores and the generalized subtype of SP was also examined. As in adults, the Mini-SPIN items differentiated subjects with SP from those without. A score of 6 points or greater was found optimal in predicting SP with a sensitivity of 86%, specificity of 84%, and positive and negative predictive values of 26% and 99%. The Mini-SPIN also possessed discriminative validity, as scores were higher for adolescents with SP than they were for those with depressive, disruptive, and other anxiety disorders. The Mini-SPIN was also able to differentiate adolescents with GSP from the rest of the sample. The Mini-SPIN has good psychometrics for screening SP in adolescents from general population and may have value in screening for GSP. Copyright © 2012 Elsevier Inc. All rights reserved.

Full Text Available The purpose of this mini-review is to provide the latest information on epidemiology, pathophysiology, diagnosis, and treatment of Tourette syndrome (TS. The authors conducted a literature search of available sources describing the issue of tic disorders with special focus on TS and made a comparison and evaluation of relevant findings. The results of this mini-review indicate that TS is a complex disorder, which has a significant impact on the quality of life of both the patients and his/her family. Therefore, early and proper diagnosis and treatment are necessary in order to reduce or even eliminate both symptoms and social burden of the patient. This requires a multidisciplinary management approach in order to meet the patients’ special needs. Future research should focus on neuroimaging, new neurotransmitter targets, in functional neurosurgery, as well as the effect of non-pharmacological psychotherapies for these people.

In this work are presented some results of the application of energy diagnoses to small companies. These diagnoses use the methodology developed by the Department of Energy of the United States of America and are performed by advanced students of engineering and university professors. The results of four energy diagnoses applied to companies of different branches are presented. In the studies the energy saving alternatives are evaluated, as well as their economic impact and their economic viability. The annual energy saving according to the company goes from 25,600 to 596,000 MJ (from 1.2 to 10.5%), which means a saving from $5,300 to $165,000 Mexican Currency (1.43 to 9.27%). The simple rate of return goes of 0.5 to 9.3 years. From the work it is concluded that the application of that methodology of energy diagnoses in Mexico is very feasible, since with very low costs opportunities of energy savings are identified and evaluated for this section of companies that traditionally have not been taken care of by the official programs and allows them to give launch to a solid program of energy improvement.

The mini-Mental Adjustment to Cancer Scale (mini-MAC) is a well-recognised, popular measure of coping in psycho-oncology and assesses five cancer-specific coping strategies. It has been suggested that these five subscales could be grouped to form the over-arching adaptive and maladptive coping subscales to facilitate the interpretation and clinical application of the scale. Despite the popularity of the mini-MAC, few studies have examined its psychometric properties among long-term cancer survivors, and further validation of the mini-MAC is needed to substantiate its use with the growing population of survivors. Therefore, this study examined the psychometric properties and dimensionality of the mini-MAC in a sample of long-term cancer survivors using Rasch analysis. RUMM 2030 was used to analyse the mini-MAC data (n=851). Separate Rasch analyses were conducted for each of the original mini-MAC subscales as well as the over-arching adaptive and maladaptive coping subscales to examine summary and individual model fit statistics, person separation index (PSI), response format, local dependency, targeting, item bias (or differential item functioning -DIF), and dimensionality. For the fighting spirit, fatalism, and helplessness-hopelessness subscales, a revised three-point response format seemed more optimal than the original four-point response. To achieve model fit, items were deleted from four of the five subscales - Anxious Preoccupation items 7, 25, and 29; Cognitive Avoidance items 11 and 17; Fighting Spirit item 18; and Helplessness-Hopelessness items 16 and 20. For those subscales with sufficient items, analyses supported unidimensionality. Combining items to form the adaptive and maladaptive subscales was partially supported. The original five subscales required item deletion and/or rescaling to improve goodness of fit to the Rasch model. While evidence was found for overarching subscales of adaptive and maladaptive coping, extensive modifications were

The Mini-Mental State Examination is one of the most widely used screening tests for the adult population in daily neurologic practice. The aim of this study was to describe and to analyze the results of the Mini-Mental State Examination administered to Spanish children and to assess the relationship between Mini-Mental State Examination scores and the child's mental age/intelligence quotient. The study population included 181 children whose ages ranged between 4 and 12 years. The neuropsychologic battery consisted of the Mini-Mental State Examination and Kaufman Brief Intelligence Test. Percentiles were obtained for the Mini-Mental State Examination total score according to age ranges. Performance gradually increased from 4 to 10 years of age when a plateau in the total Mini-Mental State Examination score was reached. At the age of 6 years, results exceeded 24 on average. Pairwise mean comparisons showed statistically significant differences between the age groups (P Mini-Mental State Examination score correlated significantly with the child's chronologic (r = 0.80, P mental (r = 0.76, P Mini-Mental State Examination in a Spanish child population as well as a first step for the assessment of the usefulness of this instrument as a cognitive screening tool for children's development.

Advances in arthroscopic techniques for rotator cuff repair have made the mini-open approach less popular. However, the mini-open approach remains an important technique for repair for many surgeons. The aims of this study were to compare the integrity of the repair, the function of the shoulder and satisfaction post-operatively using these two techniques in patients aged > 50 years. We identified 22 patients treated with mini-open and 128 patients treated with arthroscopic rotator cuff repair of July 2007 and June 2011. The mean follow-up was two years (1 to 5). Outcome was assessed using the American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test (SST) scores, and satisfaction. The integrity of the repair was assessed using ultrasonography. A power analysis ensured sufficient enrolment. There was no statistically significant difference between the age, function, satisfaction, or pain scores (p > 0.05) of the two groups. The integrity of the repair and the mean SST scores were significantly better in the mini-open group (91% of mini-open repairs were intact versus 60% of arthroscopic repairs, p = 0.023; mean SST score 10.9 (standard deviation (sd) 1.3) in the mini-open group; 8.9 (sd 3.5) in arthroscopic group; p = 0.003). The ASES scores were also higher in the mini-open group (mean ASES score 91.0 (sd 10.5) in mini-open group; mean 82.70 (sd 19.8) in the arthroscopic group; p = 0.048). The integrity of the repair and function of the shoulder were better after a mini-open repair than after arthroscopic repair of a rotator cuff tear in these patients. The functional difference did not translate into a difference in satisfaction. Mini-open rotator cuff repair remains a useful technique despite advances in arthroscopy.

Neutrino-nucleus neutral current elastic interactions measurement in MiniBooNE

Energy Technology Data Exchange (ETDEWEB)

Perevalov, Denis [Univ. of Alabama, Tuscaloosa, AL (United States)

2009-12-01

The MiniBooNE experiment at the Fermi National Accelerator Laboratory (Fermilab) was designed to search for v_μ → v_e neutrino oscillations at Δm² ~ 1 eV² using an intense neutrino flux with an average energy E_v ~ 700 MeV. From 2002 to 2009 MiniBooNE has accumulated more than 1.0 x 10²¹ protons on target (POT) in both neutrino and antineutrino modes. MiniBooNE provides a perfect platform for detailed measurements of exclusive and semiinclusive neutrino cross-sections, for which MiniBooNE has the largest samples of events up to date, such as neutral current elastic (NCE), neutral current π⁰, charged current quasi-elastic (CCQE), charged current π⁺, and other channels. These measured cross-sections, in turn, allow to improve the knowledge of nucleon structure. This thesis is devoted to the study of NCE interactions. Neutrino-nucleus neutral current elastic scattering (vN → vN) accounts for about 18% of all neutrino interactions in MiniBooNE. Using a high-statistics, high purity sample of NCE interactions in MiniBooNE, the flux-averaged NCE differential cross-section has been measured and is being reported here. Further study of the NCE cross-section allowed for probing the structure of nuclei. The main interest in the NCE cross-section is that it may be sensitive to the strange quark contribution to the nucleon spin, Δs, this however requires a separation of NCE proton (vp → vp) from NCE neutron (vn → vn) events, which in general is a challenging task. MiniBooNE uses a Cherenkov detector, which imposes restrictions on the measured nucleon kinematic variables, mainly due to the impossibility to reconstruct the nucleon direction below the Cherenkov threshold. However, at kinetic energies above this threshold MiniBooNE is able to identify NCE proton events that do not experience final state interactions (FSI). These events were used for the Δs measurement.

2013-03-01

This review provides an overview of strategies and currently available technologies used for demandside management (DSM) on mini-grids throughout the world. For the purposes of this review, mini-grids are defined as village-scale electricity distribution systems powered by small local generation sources and not connected to a main grid.1 Mini-grids range in size from less than 1 kW to several hundred kW of installed generation capacity and may utilize different generation technologies, such as micro-hydro, biomass gasification, solar, wind, diesel generators, or a hybrid combination of any of these. This review will primarily refer to AC mini-grids, though much of the discussion could apply to DC grids as well. Many mini-grids include energy storage, though some rely solely on real-time generation.

Full Text Available This study was aimed at developing risperidone oral disintegrating mini-tablets (OD-mini-tablets as age-appropriate formulations and to assess their suitability for infants and pediatric use. An experimental Box-Behnken design was applied to assure high quality of the OD-mini-tablets and reduce product variability. The design was employed to understand the influence of the critical excipient combinations on the production of OD-mini-tablets and thus guarantee the feasibility of obtaining products with dosage form uniformity. The variables selected were mannitol percent in Avicel (X1, swelling pressure of the superdisintegrant (X2, and the surface area of Aerosil as a glidant (X3. Risperidone-excipient compatibilities were investigated using FTIR and the spectra did not display any interaction. Fifteen formulations were prepared and evaluated for preand post-compression characteristics. The prepared ODmini- tablet batches were also assessed for disintegration in simulated salivary fluid (SSF, pH 6.2 and in reconstituted skimmed milk. The optimized formula fulfilled the requirements for crushing strength of 5 kN with minimal friability, disintegration times of 8.4 and 53.7 s in SSF and skimmed milk, respectively. This study therefore proposes the risperidone OD-mini-tablet formula having robust mechanical properties, uniform and precise dosing of medication with short disintegration time suitable for pediatric use.

Following treatment in an ICU, up to 70% of chronically critically ill patients present neurocognitive impairment that can have negative effects on their quality of life, daily activities, and return to work. The Mini Mental State Examination is a simple, widely used tool for neurocognitive assessment. Although of interest when evaluating ICU patients, the current version is restricted to patients who are able to speak. This study aimed to evaluate the feasibility of a visual, multiple-choice Mini Mental State Examination for ICU patients who are unable to speak. The multiple-choice Mini Mental State Examination and the standard Mini Mental State Examination were compared across three different speaking populations. The interrater and intrarater reliabilities of the multiple-choice Mini Mental State Examination were tested on both intubated and tracheostomized ICU patients. Mixed 36-bed ICU and neuropsychology department in a university hospital. Twenty-six healthy volunteers, 20 neurological patients, 46 ICU patients able to speak, and 30 intubated or tracheostomized ICU patients. None. Multiple-choice Mini Mental State Examination results correlated satisfactorily with standard Mini Mental State Examination results in all three speaking groups: healthy volunteers: intraclass correlation coefficient = 0.43 (95% CI, -0.18 to 0.62); neurology patients: 0.90 (95% CI, 0.82-0.95); and ICU patients able to speak: 0.86 (95% CI, 0.70-0.92). The interrater and intrarater reliabilities were good (0.95 [0.87-0.98] and 0.94 [0.31-0.99], respectively). In all populations, a Bland-Altman analysis showed systematically higher scores using the multiple-choice Mini Mental State Examination. Administration of the multiple-choice Mini Mental State Examination to ICU patients was straightforward and produced exploitable results comparable to those of the standard Mini Mental State Examination. It should be of interest for the assessment and monitoring of the neurocognitive

O objetivo desta revisão sistemática com meta-análise foi analisar a relação entre o índice de massa corporal (IMC e o desempenho motor no KTK em crianças e jovens escolares saudáveis. O estudo baseou-se em pesquisas indexadas nas bases eletrônicas PubMed e SciELO. Os descritores foram: "Körperkoordinationstest für Kinder" e "KTK". Foram considerados artigos em inglês e português publicados até Outubro de 2014. A qualidade dos estudos foi determinada pelas Escalas PEDro e STROBE. Foi realizada meta-análise utilizando o software Comprehensive Meta-Analysis V2. Foram incluídos 10 estudos. O resultado global com base no modelo de efeitos fixos mostrou que valores maiores de IMC estão diretamente associados ao baixo desempenho no KTK. Apesar da pequena diferença entre ambos, a magnitude do efeito da associação foi classificada como pequena, porém, significativa para o sexo masculino (r=0,29; IC95% 0,27 a 0,32; Z=22,47; p=0,000 e moderada para o sexo feminino (r=0,32; IC95% 0,30 a 0,34; Z=24,76; p=0,000. Os estudos apresentaram características amostrais bastante divergentes quanto ao tamanho da amostra e a faixa etária dos sujeitos, além de nenhum deles ter analisado o estado maturacional dos participantes. Conclui-se que há uma tendência de relação positiva entre valores elevados de IMC e o baixo desempenho no KTK. Para confirmação desta tendência, recomenda-se que os próximos trabalhos considerem o estado maturacional dos participantes, além de possibilitarem uma análise por sexo e idade.

To compare the pain status and stone free rates of flexible ureterorenoscopy (F-URS) versus mini-percutaneousnephrolithotomy (mini-PNL) for the treatment of 1-to 2-cm renal stones. This study was retrospectively designed with match paired method. Between January 2013 and December 2016, 387 patients underwent stone surgery for renal stones, 45 patients underwent FURS and 45 patients underwent mini-PNL. 90 patients were divided into two groups according to the surgical procedures. Group 1 patients underwent F-URS, and Group 2 patients underwent mini-PNL. During the intraoperative andpostoperative periods, pain management for all patients was standardized. Pain scores were determined using a visual analogue scale (VAS) completed at 2, 6, 12 and 24 hours postoperatively. The stone free status, hemoglobin levels, fluoroscopy time (FT), operation time (OT), hospitalization time (HT), return to work time (RWT), and complications were noted for each patient. Of all patients, the mean age was 41.1 ± 12.1 years and the mean stone size was 13.9 ± 2.9 mm. The VAS scores were significantly higher in the mini-PNL group at 2, 6, 12 and 24 hours (P .05); however, the hemoglobin decreases and the fluoroscopy, operation, hospitalization and return to work times were higher in the mini-PNL group than in the F-URS group (P work duration. We think that F-URS is more comfortable and less painful than mini-PNL and achieves a similar stone free rate for the treatment of 1- to 2-cm renal stones.

To demonstrate the surgical technique and advantages of the mini-open transforaminal approach for lumbar interbody fusion (TLIF) combined with transpedicular screw fixation. Clinical and radiographic results were assessed to determine the clinical outcomes in twelve consecutive patients selected for minimally invasive access (mini-open technique) for TLIF in Prasat Neurological Institute. A retrospective analysis was performed on 12 patients (age range, 38-74 yr; mean, 54. 8 yr) who underwent mini-open transforaminal approach for lumbar interbody fusion (TLIF) combined with transpedicular screw fixation between September 2006 and June 2008. The titanium pedicle screws were introduced bilaterally through the 3.5 cm length, skin incisions with Spine Classics MLD- system retractor, autologous bone graft were inserted to perform TLIF in all patients. Eight patients were augmented anterior column support with titanium interbody cage, unilateral cage insertion in four patients and the others were inserted bilaterally interbody cages. Six patients presented with low back pain and associated radiculopathy, and six presented with low back pain only. Transforaminal lumbar interbody fusion was performed at L3-L4 in two patients, L4-L5 in four patients, L5-S1 in five patients, and two levels fusion in one patient. All patients were able to ambulate after spinal fusion. The patients were able to walk within 1.4 days (range 1-2 days). The hospital stay averaged 4.4 days (range 3-7 days). Periodic follow-up took place 1 to 21 months after surgery (mean, 7.4 months). The radiological fusion was archived in all nine patients who were operated on more than two months age. The other three patients who had been follow-up less than two months were probably fusion on the 1-month followed-up radiological examination. The use of mini-open technique for pedicle screw instrumentation with spinal fusion procedure provides excellent clinical results and may be an operation of choice for

To test the idea of the Linsley effect mini array for the study of giant air showers, it is desirable to have a trigger that exploits the effect itself. In addition to the trigger, it is necessary to have a method for measuring the relative arrival times of the particle swarm selected by the trigger. Since the idea of mini arrays is likely to appeal to small research groups, it is desirable to try to design relatively simple and inexpensive methods, and methods that utilize existing detectors. Clusters of small detectors have been designed for operation in the local particle density realm where the probability of or = 2 particles per detector is small. Consequently, this method can discriminate pulses from each detector and thenceforth deal mainly with logic pulses.

Mental adjustment to cancer has been explored in a large body of the literature by using the Mental Adjustment to Cancer (MAC) scale. Problems in the factor structure of the scale and the need for refining the instrument have determined the development of the Mini-MAC. The aim of this study was to validate, according to a test-oriented approach, the Italian version of the Mini-MAC. Four hundred and thirty cancer patients in five centres in Northern Italy completed the Mini-MAC and the Brief Symptom Inventory (BSI). A subgroup of 153 patients filled out the instruments again within 3 months of the first assessment. The five original subscales (Fighting Spirit, Hopeless, Fatalism, Anxious Preoccupation and Cognitive Avoidance) showed acceptable levels of reliability (Cronbach alpha coefficients ranging from 0.55 to 0.80) although alphas were lower for the scales Fighting Spirit and Fatalism. Factor analysis (Varimax rotation) identified the same five factors with minor variations from the original version. Again, alpha coefficients were less robust for the factors Fighting Sprit and Fatalism. Hopeless and Anxious Preoccupation were significantly related to all the BSI psychological stress symptoms, including the Global Stress Index (GSI). Test-retest reliability showed no differences in the sub-scales scores between assessments. Copyright (c) 2004 John Wiley & Sons, Ltd.

The Devereux Student Strengths Assessment Mini (DESSA-Mini; Naglieri, LeBuffe, & Shapiro, 2011/2014) was designed to overcome practical obstacles to universal prevention screening. This article seeks to determine whether an entirely strength-based, 8-item screening instrument achieves technical accuracy in routine practice. Data come from a district-wide implementation of a new social emotional learning (SEL) initiative designed to promote students' social-emotional competence. All students, kindergarten through Grade 8, were screened using the DESSA-Mini. A random 5 students per classroom received additional assessment. Concurrent and predictive criterion studies were conducted using the full DESSA as well as administrative records of serious disciplinary infraction. The DESSA-Mini showed excellent internal reliability, exceeding .90. Negligible to small differences were found between scores on the DESSA-Mini screen and the DESSA full assessment. Classification consistency between the DESSA-Mini and the DESSA was high (87%-94%) in routine practice, with sensitivity and specificity estimates exceeding Glascoe's (2005) standards. Finally, predictive validity of the DESSA-Mini was reliable; students screened as having a Need for SEL Instruction at the beginning of the year were 4.5 times more likely to have a record of serious disciplinary infraction at the end of the school year compared with those who were not identified (p mental, emotional, and behavioral problems.

Nuclease dead Cas9 (dCas9) has been widely used for modulating gene expression by fusing with different activation or repression domains. However, delivery of the CRISPR/Cas system fused with various effector domains in a single adeno-associated virus (AAV) remains challenging due to the payload limit. Here, we engineered a set of downsized variants of Cas9 including Staphylococcus aureus Cas9 (SaCas9) that retained DNA binding activity by deleting conserved functional domains. We demonstrated that fusing FokI nuclease domain to the N-terminal of the minimal SaCas9 (mini-SaCas9) or to the middle of the split mini-SaCas9 can trigger efficient DNA cleavage. In addition, we constructed a set of compact transactivation domains based on the tripartite VPR activation domain and self-assembled arrays of split SpyTag:SpyCatch peptides, which are suitable for fusing to the mini-SaCas9. Lastly, we produced a single AAV containing the mini-SaCas9 fused with a downsized transactivation domain along with an optimized gRNA expression cassette, which showed efficient transactivation activity. Our results highlighted a practical approach to generate down-sized CRISPR/Cas9 and gene activation systems for in vivo applications.

Full Text Available Critical for human gene therapy is the availability of small promoters tools to drive gene expression in a highly specific and reproducible manner. We tackled this challenge by developing human DNA MiniPromoters (MiniPs using computational biology and phylogenetic conservation. MiniPs were tested in mouse as single-copy knock-ins at the Hprt locus on the X chromosome and evaluated for lacZ reporter expression in central nervous system (CNS and non–CNS tissue. Eighteen novel MiniPs driving expression in mouse brain were identified, 2 MiniPs for driving pan-neuronal expression and 17 MiniPs for the mouse eye. Key areas of therapeutic interest were represented in this set: the cerebral cortex, embryonic hypothalamus, spinal cord, bipolar and ganglion cells of the retina, and skeletal muscle. We also demonstrated that three retinal ganglion cell MiniPs exhibit similar cell type specificity when delivered via adeno-associated virus vectors intravitreally. We conclude that our methodology and characterization has resulted in desirable expression characteristics that are intrinsic to the MiniPromoter, not dictated by copy-number effects or genomic location, and results in constructs predisposed to success in adeno-associated virus. These MiniPs are immediately applicable for preclinical studies toward gene therapy in humans and are publicly available to facilitate basic and clinical research, and human gene therapy.

Full Text Available PURPOSE: The aim of this study was to critically review the Arc-to-Arc mini-sling (Palma's technique a less invasive mid-urethral sling using bovine pericardium as the sling material. MATERIALS AND METHODS: The Arc-to-Arc mini-sling, using bovine pericardium, was the first published report of a mini-sling, in 1999. The technique was identical to the "tension-free tape" operation, midline incision and dissection of the urethra. The ATFP (white line was identified by blunt dissection, and the mini-sling was sutured to the tendinous arc on both sides with 2 polypropylene 00 sutures. RESULTS: The initial results were encouraging, with 9/10 patients cured at the 6 weeks post-operative visit. However, infection and extrusion of the mini-sling resulted in sling extrusion and removal, with 5 patients remaining cured at 12 months. CONCLUSION: The Arc-to-Arc mini-sling was a good concept, but failed because of the poor technology available at that time. Further research using new materials and better technology has led to new and safer alternatives for the management of stress urinary incontinence.

2012-01-01

Mini centrifugal pumps having a diameter smaller than 100mm are employed in many fields. But the design method for the mini centrifugal pump is not established because the internal flow condition for these small-sized fluid machines is not clarified and conventional theory is not suitable for small-sized pumps. Therefore, mini centrifugal pumps with simple structure were investigated by this research. Splitter blades were adopted in this research to improve the performance and the internal flow condition of mini centrifugal pump which had large blade outlet angle. The original impeller without the splitter blades and the impeller with the splitter blades were prepared for an experiment. The performance tests are conducted with these rotors in order to investigate the effect of the splitter blades on performance and internal flow condition of mini centrifugal pump. On the other hand, a three dimensional steady numerical flow analysis is conducted with the commercial code (ANSYS-CFX) to investigate the internal flow condition in detail. It is clarified from the experimental results that the performance of the mini centrifugal pump is improved by the effect of the splitter blades. The blade-to-blade low velocity regions are suppressed in the case with the splitter blades and the total pressure loss regions are decreased. The effects of the splitter blades on the performance and the internal flow condition are discussed in this paper.

Purpose. This study evaluated the influence of recycling process on the torsional strength of mini-implants. Materials and Methods. Two hundred mini-implants were divided into 4 groups with 50 screws equally distributed in five diameters (1.3 to 1.7 mm): control group (CG): unused mini-implants, G1: mini-implants inserted in pig iliac bone and removed, G2: same protocol of group 1 followed by sonication for cleaning and autoclave sterilization, and G3: same insertion protocol of group 1 followed by sonication for cleaning before and after sandblasting (Al2O3-90 µ) and autoclave sterilization. G2 and G3 mini-implants were weighed after recycling process to evaluate weight loss (W). All the screws were broken to determine the fracture torque (FT). The influence of recycling process on FT and W was evaluated by ANOVA, Mann-Whitney, and multiple linear regression analysis. Results. FT was not influenced by recycling protocols even when sandblasting was added. Sandblasting caused weight loss due to abrasive mechanical stripping of screw surface. Screw diameter was the only variable that affected FT. Conclusions. Torsional strengths of screws that underwent the recycling protocols were not changed. Thus, screw diameter choice can be a more critical step to avoid screw fracture than recycling decision.

Full Text Available The trochoidal-gear technology has been growing in groundbreaking fields. Forthcoming applications are demanding to this technology a step forward in the conceiving stage of positive displacement machines. The compendium of the qualities and the inherent characteristics of trochoidal-gear technology, especially towards the gerotor pump, together with scale/size factor and magnetic-driven transmission has led to the idea of a magnet-sleeve-sealed variable flow mini trochoidal-gear pump. From its original concept, to the last phase of the design development, the proof of concept, this new product will intend to overcome problems such as noise, vibration, maintenance, materials, and dimensions. The paper aims to show the technological path followed from the concept, design, and model, to the manufacture of the first prototype, where the theoretical and numerical approaches are not always directly reflected in the prototype performance results. Early in the design process, from a standard-commercial sintered metal mini trochoidal-gear unit, fundamental characteristics and dimensional limitations have been evaluated becoming the strategic parameters that led to its configuration. The main technical challenge to confront is being sealed with non-exterior driveshaft, ensuring that the whole interior is filled and wetted with working fluid and helping the hydrodynamic film formation, the pumping effect, and the heat dissipation. Subsequently, the mini pump architecture, embodiment, methodology, materials, and manufacture are presented. The trend of applications of polymer composite materials and their benefits wanted to be examined with this new mini pump prototype, and a pure polyoxymethylene mini trochoidal-gear set has been designed and manufactured. Finally, both the sintered and the polymer trochoidal-gear units have been experimentally tested in an in-house full-instrumented mini test bench. Although the main goal of the presented work is the

The Mini Asthma Quality of Life Questionnaire (MiniAQLQ) is a validated disease-specific quality of life (QOL) paper (p) questionnaire. Electronic (e) versions enable inclusion of asthma QOL in electronic medical records and research databases. To validate an e-version of the MiniAQLQ, compare time required for completion of e- and p-versions, and determine which version participants prefer. Adults with stable asthma were randomized to complete either the e- or p-MiniAQLQ, followed by a 2-h rest period before completing the other version. Agreement between versions was measured using the intraclass correlation coefficient (ICC) and Bland-Altman analysis. Two participants with incomplete p-MiniAQLQ responses were excluded. Forty participants (85% female; age 47.7 +/- 14.9 years; asthma duration 22.6 +/- 16.1 years; FEV(1) 87.1 +/- 21.6% predicted) with both AQLQ scores limitation, emotional function and environmental stimuli domains were 0.94, 0.89, 0.90, and 0.91 respectively. A small but significant bias (Delta=0.3; P=0.004) was noted in the activity limitation domain. Completion time was significantly longer for the e-version (3.8 +/- 1.9min versus 2.7 +/- 1.1min; Ppreferred the e-MiniAQLQ; 35% had no preference. This e-version of the MiniAQLQ is valid and was preferred by most participants despite taking slightly longer to complete. Generalizabilty may be limited in younger (12-17) and older (>65) adults.

Full Text Available Estudos ao longo do Globo têm mostrado que a mecanização da poda, dentre outros processos de manejo da videira, é adequada para a obtenção de vinhedos com “stands” bem formados e com qualidade de produção equivalente ou superior àqueles conduzidos sob manejo manual, sobretudo com economia de capital humano e financeiro. Informações sobre o padrão de poda que influencia diretamente a ecofisiologia do dossel, a composição do rendimento e a qualidade de derivados da uva são existentes para condições de manejo tradicional manual, mas incipientes para a uma condição mecanizada, no Brasil. Um experimento foi realizado com Vitis sp. e Vitis vinifera, visando a estudar os impactos da adoção inicial da poda mecanizada, sobre a composição do rendimento, qualidade da uva e perfil sensorial dos vinhos produzidos no experimento. Os resultados mostraram que a aplicação da poda mecanizada em vinhedos tradicionais causou pequenas flutuações na qualidade da uva, em duas safras analisadas.

Patients with atrophic edentulous ridges generally have problems with retention, therapeutic satisfaction, and comfort with their complete dentures. An alternative treatment to assist in improving retention and stability involves the use of mini-implants. The aim of this study was to evaluate the retention of mandibular overdentures connected to two mini-implants and overall patient satisfaction with them. Seven patients with atrophic mandibular ridges (Type 4D Misch classification), aged 62 to 74 years old were rehabilitated with complete dentures. In each patient, two mini-implants measuring 15 or 13 mm in length and 1.8 mm in diameter were placed. After 15 days, overdentures were connected to the mini-implants with O-ring attachments. In each patient, retention of the overdentures was measured, and a survey of therapeutic satisfaction before and after connection to the mini-implants was administered. Prosthesis retention was measured with a digital dynamometer at 1 month, 6 months, and 2, 3, 5, and 7 years after mini-implant placement. Patient satisfaction was assessed with a survey. Data were analyzed with Student's t-test (satisfaction survey) and the Friedman test (retention measurements and satisfaction survey). The initial retention values (0.34 to 0.63 N without mini-implants) varied significantly (p ≤ 0.050). These values were less than the subsequent measurements of 3.92 to 9.64 N, taken after placement of the mini-implants and connecting them to the dentures. Satisfaction was good to very good over the 7-year observation period. Mucosa and peri-implant bone showed no pathological changes. In this limited sample size clinical study the results indicated that after connecting mandibular overdentures to two mini-implants, patient satisfaction significantly increased and retention significantly improved during the 7-year observation period. © 2015 by the American College of Prosthodontists.

Full Text Available Este artigo busca identificar os principais impactos na mobilidade e acessibilidade local percebidos pela população de uma pequena cidade após a duplicação de uma rodovia federal. O modelo de travessia urbana adotado configura uma barreira, que exige a adoção de medidas mitigadoras para diminuir seus impactos no funcionamento da cidade e os conflitos entre o tráfego local e o tráfego de passagem. A metodologia aborda as alterações de hábitos de mobilidade na cidade antes e depois da duplicação da rodovia, levantando dados sobre a modificação dos percursos diários, o tempo de deslocamento, e a identificação da rodovia duplicada como barreira urbanística, buscando contrapor esses dados com as soluções adotadas no projeto. O projeto de duplicação do trecho da BR 101 que passa pelo município de Goianinha, Rio Grande do Norte, apresenta características que privilegiam o trânsito de passagem em detrimento da população.  Como resultados, efeitos indiretos e de longo prazo começam a ser percebidos pelos entrevistados, ao identificarem quebra da continuidade das relações sociais e econômicas entre as partes da cidade , assim como, um início de mudança de hábitos e locais de compras, forçados por alterações no uso do solo, que começam a ocorrer nas margens da rodovia.

Objective: To evaluate the effectiveness of mini-transverse compared with mini-longitudinal incision for carpal tunnel release (CTR) with reference to postoperative functional capacity, symptom severity and complication rate. Study Design: Analytical study. Place and Duration of Study: Cumhuriyet University Medical Faculty, Department of Orthopaedics, Tokat State Hospital, Department of Orthopaedics and Medical Park Tokat Hospital, Department of Neurosurgery, from January 2007 to January 2009. Methodology: This study included 93 hands of 79 patients with carpal tunnel syndrome (CTS), which were operated between 2007 and 2009. Patients were divided according to incision types into Group-1 (undergoing mini-longitudinal incision) and Group-2 (undergoing mini-transverse incision). Patients were evaluated initially and at 3 weeks after treatment according to symptom severity and functional status of Boston Questionnaire (BQ). Demographic and clinical data were analyzed and compared statistically between two groups. Results: Statistically significant differences were observed in BQ symptom and functional scores between the pre- and postoperative period (p < 0.0001). BQ symptom and functional scores at postoperative period were better in Group-1 than Group-2 (p = 0.044 and p = 0.023 respectively). The scar hypersensitivity (p = 0.258) and tenderness (p = 1.00) associated with the incision sites were not statistically different. Conclusion: Longitudinal incision is more effective on symptom and functional conditions than transverse incision. However, there was less scar formation with transverse incision. (author)

Full Text Available Contínuas mudanças econômicas e culturais estão causando transformações no funcionamento das famílias e na educação das crianças pequenas em todas as camadas sociais. Essas transformações têm contribuído para o aumento da demanda e implementação de políticas de educação/cuidado infantil. Avanços políticos e legais têm ocorrido em vários países, nas últimas décadas. Esse processo configura-se sob formas diversas nos países desenvolvidos e nos em desenvolvimento. Naqueles e, em especial, nos países da Comunidade Européia, as justificativas para essas políticas fundamentam-se em um discurso pelos direitos da criança quanto ao acesso à educação e aos bens culturais, e pela igualdade de direitos e oportunidades de homens e mulheres. Já nos países em desenvolvimento, o discurso para ricos e pobres é bastante diferenciado, particularmente quando estabelece políticas para expansão do atendimento. Quando o alvo é a população pobre, negra e de zona rural, essas políticas se pautam por um discurso da necessidade de atender pobremente a pobreza, que transparece de maneira clara nos documentos do Banco Mundial. Neste artigo, propomo-nos a fazer uma reflexão crítica sobre as políticas para a infância nos países em desenvolvimento, tomando a América Latina como estudo de caso.Continuous economical and cultural changes are inducing various transformations in family functioning and young children education and care.

This study was aimed to explore students' learning response toward feedback during mini-CEX encounter. This study used a phenomenological approach to identify the students' experiences toward feedback during mini-CEX encounter. Data was collected using Focus Group Discussion (FGD) for all students who were in their final week of clerkship in the internal medicine rotation. There were 4 FGD groups (6 students for each group). All FGD were audio-taped and transcribed verbatim. The FGD transcripts were analyzed thematically and managed using Atlas-ti (version 7.0). Feedback content and the way of providing feedback on mini-CEX stimulated students' internal process, including self-reflection, emotional response, and motivation. These internal processes encouraged the students to take action or do a follow-up on the feedback to improve their learning process. In addition, there was also an external factor, namely consequences, which also influenced the students' reaction to the follow-up on feedback. In the end, this action caused several learning effects that resulted in the students' increased self-efficacy, attitude, knowledge and clinical skill. Feedback content and the way of providing feedback on mini-CEX stimulates the students' internal processes to do a follow-up on feedback. However, another external factor also affects the students' decision on the follow-up actions. The follow-ups result in various learning effects on the students. Feedback given along with summative assessment enhances learning effects on students, as well. It is suggested that supervisors of clinical education are prepared to comprehend every factor influencing feedback on mini CEX to improve the students' learning response.

We validate the Mini-SPIN and its diagnostic efficiency in overcoming this problem in Spanish-speaking adolescents in Spain. Methods The psychometric properties of the 3-item Mini-SPIN scale for adolescents were assessed in a community (study 1) and clinical sample (study 2). Results Study 1 consisted of 573 adolescents, and found the Mini-SPIN to have appropriate internal consistency and high construct validity. Study 2 consisted of 354 adolescents (147 participants diagnosed with SAD and 207 healthy controls). Data revealed that the Mini-SPIN has good internal consistency, high construct validity and adequate diagnostic efficiency. Conclusions Our findings suggest that the Mini-SPIN has good psychometric properties on clinical and healthy control adolescents and general population, which indicates that it can be used as a screening tool in Spanish-speaking adolescents. Cut-off scores are provided. PMID:26317695

Ectodermal dysplasia is a rare congenital disease that affects several structures of ectodermal origin. The most commonly related oral characteristics are hypodontia, malformed teeth and underdeveloped alveolar ridges. New alternative treatments are needed due to the failure of the conventional prosthesis retention. This case report outlines the oral rehabilitation treatment of a 9-year-old girl with ectodermal dysplasia. The treatment was performed with conventional prosthesis upon mini-implants. The mini-implants provided prosthetic retention. The patient reported a good adaptation of the dental prosthesis and satisfaction with the treatment. The increased self-esteem improved the socialization skills of the girl. In this case report, use of prosthesis with mini-implants was satisfactory for prosthetic retention. However, clinical studies with long-term follow-up are needed to test the mini-implants as an alternative for oral rehabilitation of children with ectodermal dysplasia.

The MiniGRAIL detector was improved. The sphere was replaced by a slightly larger one, having a diameter of 68 cm (instead of 65 cm), reducing the resonant frequency by about 200 Hz to around 2.9 kHz. The last four masses of the attenuation system were machined to increase their resonant frequency and improve the attenuation around the resonant frequency of the sphere. In the new sphere, six holes were machined on the TIGA positions for easy mounting of the transducers. During the last cryogenic run, two capacitive transducers and a calibrator were mounted on the sphere. The first transducer was coupled to a double-stage SQUID amplifier having a commercial quantum design SQUID as a first stage and a DROS as a second stage. The second transducer was read by a single-stage quantum design SQUID. During the cryogenic run, the sphere was cooled down to 4 K. The two-stage SQUID had a flux noise of about 1.6 μφ 0 Hz -1/2 . The detector was calibrated and the sensitivity curve of MiniGRAIL was determined

The Lagrangian structure of ozone mini-holes and potential vorticity anomalies in the Northern Hemisphere

2002-06-01

Full Text Available An ozone mini-hole is a synoptic-scale area of strongly reduced column total ozone, which undergoes a growth-decay cycle in association with baroclinic weather systems. The tracks of mini-hole events recorded during the TOMS observation period over the Northern Hemisphere provide a database for building anomaly fields of various meteorological parameters, following each mini-hole center in a Lagrangian sense. The resulting fields provide, for the first time, a complete mean Lagrangian picture of the three-dimensional structure of typical ozone mini-holes in the Northern Hemisphere. Mini-holes are shown to be associated with anomalous warm anticyclonic flow in the upper troposphere and cold cyclonic anomalies in the middle stratosphere. Ascending air columns occur upstream and descent downstream of the mini-hole centers. Band-pass filtering is used to reveal the transient synoptic nature of mini-holes embedded within larger scale circulation anomalies. Significant correlations between ozone and Ertel’s potential vorticity on isentropes (IPV both near the tropopause and in the middle stratosphere are shown and then utilized by reconstructing the Lagrangian analysis to follow local IPV anomalies instead of ozone minima. By using IPV as a proxy for ozone, the geopotential anomaly dipolar structure in the vertical characteristic of mini-holes is shown to result from a superposition of two largely independent dynamical components, stratospheric and tropospheric, typically operating on different time scales. Hence, ozone mini-holes may be viewed primarily as phenomena of coincidence.Key words. Meteorology and atmospheric dynamics (middle atmosphere dynamics; synoptic-scale meteorology

Gaber, Dina M; Nafee, Noha; Abdallah, Osama Y

2015-07-05

Whether mini-tablets (tablets, diameters ≤6mm) belong to single- or multiple-unit dosage forms is still questionable. Accordingly, Pharmacopoeial evaluation procedures for mini-tablets are lacking. In this study, the aforementioned points were discussed. Moreover, their potential for oral controlled delivery was assessed. The antidepressant venlafaxine hydrochloride (Vx), a highly soluble drug undergoing first pass effect, low bioavailability and short half-life was selected as a challenging payload. In an attempt to weigh up mini-tablets versus pellets as multiparticulate carriers, Vx-loaded mini-tablets were compared to formulated pellets of the same composition and the innovator Effexor(®)XR pellets. Formulations were prepared using various polymer hydrogels in the core and ethyl cellulose film coating with increasing thickness. Mini-tablets (diameter 2mm) showed extended Vx release (<60%, 8h). Indeed, release profiles comparable to Effexor(®)XR pellets were obtained. Remarkably higher coating thickness was required for pellets to provide equivalent retardation. Ethyl cellulose in the core ensured faster release due to polymer migration to the surface and pore formation in the coat. mini-tablets showed higher stability to pellets upon storage. Industrially speaking, mini-tablets proved to be superior to pellets in terms of manufacturing, product quality and economical aspects. Results point out the urgent need for standardized evaluation procedures for mini-tablets. Copyright © 2015. Published by Elsevier B.V.

Em 2006 são previstos mais de 3500 novos casos, dos quais 20% serão diagnosticados como carcinoma do pulmão de pequenas células (CPPC. Destes, 25% a 30% dos doentes serão estadiados como doença localizada ou regional. Para estes, a opção terapêutica passa pela combinação da radioterapia (50 Gy ou 60 Gy diária e quimioterapia. A radioterapia hiperfraccionada, em consequência da sua toxicidade, está limitada a doentes seleccionados.A combinação etopósido e cisplatina é sinérgica, bem tolerada. É o regimen standard quer na opção concomitante com a radioterapia, quer isoladamente na doença disseminada.Apesar da quimiossensibilidade e radiosensibilidade, o prognóstico global do CPPC é pobre. Há um desenvolvimento precoce de resistência associado a uma elevada predisposição para a recidiva.A terapêutica de segunda linha para o CPPC é um problema real e actual. Topotecano é hoje uma opção efectiva e bem tolerada no tratamento em segunda linha do CPPC. Há um aumento significativo da sobrevivência mediana versus a terapêutica sintomática. A sua eficácia é comparável ao clássico regimen CAV. Mostra boa tolerabilidade mesmo quando administrado em doentes idosos, com PS=2. Continua a ser bem tolerado e eficaz quando combinado com a radioterapia holocraniana cerebral ou quando administrado num esquema semanal.Com novas classes de fármacos, como agentes antiangiogénicos como o bevacizumab, inibidores da tirosina quinase e talidomida, decorrem ensaios avaliando a sua associação com a clássica quimioterapia em doentes com CPPC disseminada.

Full Text Available This study aims to report the use of mini-scleral contact lens in the management of mucous membrane pemphigoid (MMP with persistent epithelial defects. A 68-year-old male with a history of ocular pain and declining visual acuity was referred to our clinic with a diagnosis of MMP. His corrected distance visual acuity (CDVA was 20/200 in the right eye and 20/100 in the left eye. Despite being on lubricants, topical steroids and intravenous cyclophosphamide, the patient developed persistent corneal epithelial defects in both eyes. He was then given a trial of mini-scleral lenses. Within 4 weeks, corneal epithelial defects healed, and at 6 months, the CDVA had improved to 20/50 in the right eye and 20/40 in the left eye. By improving the corneal surface integrity and visual function, mini-scleral lenses can play a role in the visual rehabilitation of patients with MMP.

A cost comparison for individual and mini grid photovoltaic systems is made regarding the use of these systems for rural electrification in Northern Brazil. The estimates for maintenance costs were based on existing experience for individual systems already operating in the region. A comparison was also made between modified automotive lead acid batteries commonly used in photovoltaic systems in Brazil and the much more expensive OPzS tubular types. The results of these evaluations show that the maintenance costs are expected to be lower in the case of the mini grids than in individual systems. This is because for a given number of houses to be supplied with electrical energy, they use a smaller number of components subject to failures, like inverters and charge controllers. OPzS batteries are expected to compensate for their higher prices if their predicted operating lifetime can be confirmed under the practical conditions envisaged. (author)

Liden, Goeran; Surakka, Jouni

2009-01-01

A small personal aerosol mini-sampler to be used inside modern welding visors has been developed. The main object of the mini-sampler has been to sample manganese. The sampler is based on commercially available 13 mm filter holders but modified to incorporate an inlet nozzle made of aluminium. The nominal flow rate of the mini-sampler is 0,75 l/min. The sampler is to be worn mounted on a headset, modified from professional microphone headsets. The headset mounting arrangement was accepted by the welders. The sampling bias of the mini sampler versus the IOM sampler depends on the coarseness of the sampled aerosol. At the lowest concentration ratio of the open-face 25 mm filter holder to the IOM sampler equal to 0,65, the bias of the mini sampler is approximately -26% versus the IOM. The RMS sampling bias of the mini sampler versus the IOM sampler for manganese is -4,6%. The inhalable fraction of welding aerosol mass consists only of 25-55% of welding fume. The rest of the mass is made up of spatter particles and grinding particles. For manganese generally more than 65% is found in the fume.

Bitter tasting drugs represent a large portion of active pharmaceutical ingredients. Mini-tablets are specifically designed for patients with difficulty in swallowing particular in young children up to 10 years of age, geriatric patients and patients with esophagitis. The present study was aimed to prepare, taste-masked mini-tablets, which are easily swallowed dosage forms, primarily to be used by pediatric and geriatric patients. Ketoprofen (10%-50% w/w) and Eudragit® EPO were blended and extruded with a 5-mm strand die and cut into consistent mini-tablets by using an adapted downstream pelletizer. Differential scanning calorimetry and polarized light microscopy-hot stage microscopy studies confirmed that the binary mixtures were miscible under the employed extrusion temperatures. In-vitro release studies showed that drug release was less than 0.5% within the first 2 min in simulated salivary fluid (pH 6.8) and more than 90% in the first 20 min in gastric media (pH 1.0). The results of the electronic tongue analysis were well correlated with the drug release profile of the mini-tablets in the artificial saliva. Scanning electron microscopy revealed no cracks on the surface of the minitablets, confirming that the mini-tablets were compact solids. Chemical imaging confirmed the uniform distribution of ketoprofen inside the polymer matrices. Eudragit® EPO containing ketoprofen at various drug loads were successfully melt extruded into tastedmasked mini-tablets. The reduced drug release at salivary pH correlated well with Astree e-Tongue studies for taste masking efficiency.

Most of Chinese medicinal herbs are subjected to traditional processing procedures, including stir-frying, charring, steaming, boiling, and calcining before they are released into dispensaries. The marketing and identification of processed medicinal materials is a growing issue in the marketplace. However, conventional methods of identification have limitations, while DNA mini-barcoding, based on the sequencing of a short-standardized region, has received considerable attention as a new potential means to identify processed medicinal materials. In the present study, six DNA barcode loci including ITS2, psbA-trnH, rbcL, matK, trnL (UAA) intron and its P6 loop, were employed for the authentication of 45 processed samples belonging to 15 species. We evaluated the amplification efficiency of each locus. We also examined the identification accuracy of the potential mini-barcode locus, of trnL (UAA) intron P6 loop. Our results showed that the five primary barcode loci were successfully amplified in only 8.89%-20% of the processed samples, while the amplification rates of the trnL (UAA) intron P6 loop were higher, at 75.56% successful amplification. We compared the mini-barcode sequences with Genbank using the Blast program. The analysis showed that 45.23% samples could be identified to genus level, while only one sample could be identified to the species level. We conclude that trnL (UAA) p6 loop is a candidate mini-barcode that has shown its potential and may become a universal mini-barcode as complementary barcode for authenticity testing and will play an important role in medicinal materials control.

2016-01-01

Objective This study was aimed to explore students’ learning response toward feedback during mini-CEX encounter. Methods This study used a phenomenological approach to identify the students’ experiences toward feedback during mini-CEX encounter. Data was collected using Focus Group Discussion (FGD) for all students who were in their final week of clerkship in the internal medicine rotation. There were 4 FGD groups (6 students for each group). All FGD were audio-taped and transcribed verbatim. The FGD transcripts were analyzed thematically and managed using Atlas-ti (version 7.0). Results Feedback content and the way of providing feedback on mini-CEX stimulated students’ internal process, including self-reflection, emotional response, and motivation. These internal processes encouraged the students to take action or do a follow-up on the feedback to improve their learning process. In addition, there was also an external factor, namely consequences, which also influenced the students’ reaction to the follow-up on feedback. In the end, this action caused several learning effects that resulted in the students’ increased self-efficacy, attitude, knowledge and clinical skill. Conclusions Feedback content and the way of providing feedback on mini-CEX stimulates the students’ internal processes to do a follow-up on feedback. However, another external factor also affects the students’ decision on the follow-up actions. The follow-ups result in various learning effects on the students. Feedback given along with summative assessment enhances learning effects on students, as well. It is suggested that supervisors of clinical education are prepared to comprehend every factor influencing feedback on mini CEX to improve the students’ learning response. PMID:28008136

The Norwegian version of the Mini-Mental Adjustment to Cancer Scale: factor structure and psychometric properties.

2010-02-01

The object of the study was to examine the factor structure and the psychometric properties of the Mini-Mental Adjustment to Cancer Scale (Mini-MAC) among a large sample of Norwegian breast cancer patients. A total of 402 patients with breast cancer completed the Mini-MAC. Principal component analysis with varimax rotion confirmed four factors. Three had psychometric properties to the original Mini-MAC Helpless-Hopeless (HH), Anxious Preoccupation (AP) and Cognitive Avoidance (CA) subscales. The fourth, named Positive Attitude (PA) combined the Fighting Spirit (FS) and the Fatalism subscales of the original Mini-MAC. Construct validities were assessed by examining the interscale correlations as well as the correlations between the Mini-MAC subscales and the HADS subscales scores. Internal consistency of the five subscales was satisfactory for the original (HH, AP, CA, FA, coefficients=0.60-0.83), except for the FS subscale (coefficient=21). In view of the low internal reliability for the Norwegian Mini-MAC FS subscale coefficient; it appears to be more appropriate to use the Norwegian Mini-MAC as a four-factor model. If researcher or clinicians in Norway use the five-factor model, they should take great care when interpreting the fighting spirit subscale.

From Rindler horizon to mini black holes at LHC

Recently researchers (A. Sepehri et al., Astrophys. Space Sci. 344, 79 (2013)) have considered the signature of superstring balls near mini black holes at LHC and calculate the information loss for these types of strings. Motivated by their work, we consider the evolution of events in high energy experiments from lower energies for which the Rindler horizon is formed to higher energies in which mini black holes and string balls are emerged. Extending the Gottesman and Preskill method to string theory, we find the information loss for excited strings ''string balls'' in mini black holes at LHC and calculate the information transformation from the collapsing matter to the state of outgoing Hawking radiation for strings. We come to the conclusion that information transformation for high energy strings is complete. Then the thermal distribution of excited strings near mini black holes at LHC is calculated. In order to obtain the total string cross section near black holes produced in proton-proton collision, we multiply the black hole production cross section by the thermal distribution of strings. It is observed that many high energy excited strings are produced near the event horizon of TeV black holes. These excited strings evaporate to standard model particles like Higgs boson and top quark at Hagedorn temperature. We derive the production cross section for these particles due to string ball decay at LHC and consider their decay to light particles like bottom quarks and gluons. (orig.)

Objective: The dosimetric characterization of an accessory-mounted mini-beam collimator across three beam matched linear accelerators. Materials and Methods: Percent depth dose and profiles were measured for the open and mini-beam collimated fields. The average beam quality and peak-to-valley dose ratio (PVDR), the ratio of average peak dose to average valley dose, were obtained from these measurements. The open field relative output and the mini-beam collimator factor, the ratio of the mini-beam dose to open field dose at the beam center, were measured for square fields of side 2, 3, 4, and 5 cm. Mini-beam output as a function of collimator inclination angle relative to the central axis was also investigated. Results and Discussion: Beam quality for both the open and mini-beam collimated fields agreed across all linacs to within ±1.0%. The PVDR was found to vary by up to ±6.6% from the mean. For the 2, 3, and 4 cm fields the average open field relative output with respect to the 5 cm field was 0.874±0.4%, 0.921±0.3%, and 0.962±0.1%. The average collimator factors were 0.450±3.9%, 0.443±3.9%, 0.438±3.9%, and 0.434±3.9%. A decrease in collimator factor greater than 7% was found for an inclination angle change of 0.09°. Conclusion: The mini-beam collimator has revealed a difference between the three linacs not apparent in the open field data, yet transferability can still be attained through thorough dosimetric characterization.

Objective: The dosimetric characterization of an accessory-mounted mini-beam collimator across three beam matched linear accelerators. Materials and Methods: Percent depth dose and profiles were measured for the open and mini-beam collimated fields. The average beam quality and peak-to-valley dose ratio (PVDR), the ratio of average peak dose to average valley dose, were obtained from these measurements. The open field relative output and the mini-beam collimator factor, the ratio of the mini-beam dose to open field dose at the beam center, were measured for square fields of side 2, 3, 4, and 5 cm. Mini-beam output as a function of collimator inclination angle relative to the central axis was also investigated. Results and Discussion: Beam quality for both the open and mini-beam collimated fields agreed across all linacs to within ±1.0%. The PVDR was found to vary by up to ±6.6% from the mean.

Research on UMo fuel for research reactor has been developed. The fuel of research reactor is uranium molybdenum low enrichment with high density. For supporting the development of fuel fabrication, an neutronic analysis of mini fuel plates in the RSG-GAS core was performed. The aim of analysis is to determine the numbers of fuel cycles in the core to know the maximum fuel burn-up. The mini fuel plates of U_7Mo-Al and U_6Zr-Al with densities of 7.0 gU/cc and 5.2 gU/cc, respectively, will be irradiated in the RSG-GAS core. The size of both fuels, namely 630 x 70.75 x 1.30 mm were inserted to the 3 plates of dummy fuel. Before the fuel will be irradiated in the core, a calculation for safety analysis from neutronics and thermal-hydraulics aspects were required. However, in this paper, it will be discussed safety analysis of the U_7Mo-Al and U_6Zr-Al mini fuels from neutronic point of view. The calculation was done using WIMSD-5B and Batan-3DIFF codes. The result showed that both of the mini fuels could be irradiated in the RSG-GAS core with burn up less than 70 % within 12 cycles of operation without over limiting the safety margin. If it is compared, the power density of U_7Mo-Al mini fuel is bigger than U_6Zr-Al fuel. (author)

Microtubules, the dynamic, yet stiff hollow tubes built from αβ-tubulin protein heterodimers, are thought to be present only in eukaryotic cells. Here, we report a 3.6-Å helical reconstruction electron cryomicroscopy structure of four-stranded mini microtubules formed by bacterial tubulin-like Prosthecobacter dejongeii BtubAB proteins. Despite their much smaller diameter, mini microtubules share many key structural features with eukaryotic microtubules, such as an M-loop, alternating subunits, and a seam that breaks overall helical symmetry. Using in vitro total internal reflection fluorescence microscopy, we show that bacterial mini microtubules treadmill and display dynamic instability, another hallmark of eukaryotic microtubules. The third protein in the btub gene cluster, BtubC, previously known as "bacterial kinesin light chain," binds along protofilaments every 8 nm, inhibits BtubAB mini microtubule catastrophe, and increases rescue. Our work reveals that some bacteria contain regulated and dynamic cytomotive microtubule systems that were once thought to be only useful in much larger and sophisticated eukaryotic cells.

Full Text Available Two-implant overdentures have become the accepted treatment for restoring mandibular edentulism. The dimensions of regular implants sometimes limit their use, such as in the case of narrow ridges. Mini-implants with reduced diameters (less than 3.0 mm enable insertion into narrow ridges. A magnet-retained two-mini-implant overdenture system was developed and is described in this paper. Additionally, we describe a clinical mandibular procedure using the system and evaluate its biomechanical performance.

To investigate the bonding efficacy of a multimode adhesive to plasma-treated and -untreated (control) dentin using a mini-interfacial fracture toughness (mini-iFT) test. Twenty human molars were used in a split-tooth design (n = 10). The adhesive Scotchbond Universal (SBU; 3M ESPE) was applied in etch-and-rinse (E&R) and self-etch (SE) modes. Mid-coronal dentin was exposed and covered with a standardized smear layer ground to 320 grit. One half of each dentin surface received 15 s of non-thermal atmospheric plasma (NTAP), while the other half was covered with a metallic barrier and kept untreated. Following the E&R mode, dentin was plasma treated immediately after phosphoric acid etching. SBU and a resin-based composite were applied to dentin following the manufacturer's instructions. Six mini-iFT specimens were prepared per tooth (1.5 x 2.0 x 16 to 18 mm), and a single notch was prepared at the adhesive-dentin interface using a 150-μm diamond blade under water cooling. Half of the mini-iFT specimens were immediately loaded until failure in a 4-point bending test, while the other half were first stored in distilled water for 6 months. After testing, the exact dimensions of the notch were measured with a measuring optical microscope, from which ΚIc was determined. Three-way ANOVA revealed higher mini-iFT for SBU applied in E&R than SE mode for both storage times, irrespective of NTAP treatment. Overall, mini-iFT did not decrease for any of the experimental groups upon 6-month aging, while plasma treatment did not show a direct beneficial effect on mini-iFT of SBU applied in either E&R or SE mode.

Orthodontic mini-implants are important devices for successful anchorage management in orthodontics; however, the survival of these devices depends on several clinical factors. The aim of our study was to calculate the success and complication rates of orthodontic mini-implants. In this retrospective study, patients of our orthodontic department were enrolled, getting overall 59 orthodontic mini-implants during their orthodontic treatment in a 2-year period. Every patient had one or more of the 1.6 mm × 8 mm in size self-drilling mini-implants (Jeil Dual Top Anchor System, Jeil Medical Corp., Seoul, Korea). Screw loading was performed immediately after insertions, keeping tension forces under 150 g. Soft tissue and bone infections, implant mobility and screw loss, implant fracture, and neighboring tooth injury were registered. Relationships between variables were tested using the Chi-square test for statistical significance. The success rate of the orthodontic mini-implants was 89.8% in this study while the average loading period was 8.1 months. Soft-tissue infections varied between 6.3% and 33.3% of the cases while screw mobility varied between 3.1% and 20.8% of the cases regarding the anatomic localization. Screw mobility was significantly more frequent in the buccal fold than in the palate (P = 0.034). Screw mobility was significantly more frequent in the buccal fold than in the palate (P = 0.034) and screw mobility was found more frequently in case of intrusions than by extrusions (P = 0.036). The overall success rate of mini-implants was found acceptable in this study, however, screw mobility in the buccal fold showed a high incidence, suggesting the thorough consideration of the immediate loading by buccal mini-implants.

We have designed and fabricated a miniature microscope from off-the-shelf components and a webcam, with built-in fluorescence capability for biomedical applications. The mini-microscope was able to detect both biochemical parameters, such as cell/tissue viability (e.g. live/dead assay), and biophysical properties of the microenvironment such as oxygen levels in microfabricated tissues based on an oxygen-sensitive fluorescent dye. This mini-microscope has adjustable magnifications from 8-60×, achieves a resolution as high as microscope was able to chronologically monitor cell migration and analyze beating of microfluidic liver and cardiac bioreactors in real time, respectively. The mini-microscope system is cheap, and its modularity allows convenient integration with a wide variety of pre-existing platforms including, but not limited to, cell culture plates, microfluidic devices, and organs-on-a-chip systems. Therefore, we envision its widespread application in cell biology, tissue engineering, biosensing, microfluidics, and organs-on-chips, which can potentially replace conventional bench-top microscopy where long-term in situ and large-scale imaging/analysis is required.

The early development of mini hydro development in Peninsular Malaysia was carried out by the National Electricity Board (NEB) and the projects developed in the 50s and 60s were Ulu Langat (Selangor), Sempam, Kg. Raja , Kuala Terla, and Robinson Falls (all in Pahang). In the 70s the main effort of hydropower development was concentrated on developing major hydropower projects not only to cater to the country increasing demand for electricity but also to the country needs for flood control. This development was feverishly carried out on the Perak River and the prohects built were Temenggor (384 MW), Bersia (72 MW), Kenering (20 MW), Sg Piah (70 MW) and the Kenyir (400 MW) project in Sungai Terengganu. In late 1970s, the government was keen to electrify the rural areas of Peninsular Malaysia and mini hydro power development was thought of as an option to provide electricity to these areas. The Mini Hydro Department of National Electricity Board (MHD) was then formed to undertake the task of planning, developing and implementing mini hydro projects to meet this government aspiration. Table 1 shows the list of projects identified and implemented and its status

Mini Geriatric E-Learning Modules (Mini-GEMs) are short, focused, e-learning videos on geriatric medicine topics, hosted on YouTube, which are targeted at junior doctors working with older people. This study aimed to explore how these resources are accessed and used. The authors analyzed the viewing data from 22 videos published over the first 18 months of the Mini-GEM project. We conducted a focus group of U.K. junior doctors considering their experiences with Mini-GEMS. The Mini-GEMs were viewed 10,291 times over 18 months, equating to 38,435 minutes of total viewing time. The average viewing time for each video was 3.85 minutes. Learners valued the brevity and focused nature of the Mini-GEMs and reported that they watched them in a variety of settings to supplement clinical experiences and consolidate learning. Watching the videos led to an increase in self-reported confidence in managing older patients. Mini-GEMs can effectively disseminate clinical teaching material to a wide audience. The videos are valued by junior doctors due to their accessibility and ease of use.

Mathematics authentic assessment is a form of meaningful measurement of student learning outcomes for the sphere of attitude, skill and knowledge in mathematics. The construction of attitude, skill and knowledge achieved through the fulfilment of tasks which involve active and creative role of the students. One type of authentic assessment is student mini projects, started from planning, data collecting, organizing, processing, analysing and presenting the data. The purpose of this research is to learn the process of using authentic assessments on statistics learning which is conducted by teachers and to discuss specifically the use of mini projects to improving students’ learning in the school of Surakarta. This research is an action research, where the data collected through the results of the assessments rubric of student mini projects. The result of data analysis shows that the average score of rubric of student mini projects result is 82 with 96% classical completeness. This study shows that the application of authentic assessment can improve students’ mathematics learning outcomes. Findings showed that teachers and students participate actively during teaching and learning process, both inside and outside of the school. Student mini projects also provide opportunities to interact with other people in the real context while collecting information and giving presentation to the community. Additionally, students are able to exceed more on the process of statistics learning using authentic assessment.

The goal of this work was to design, build and experimentally characterize a linear accelerator mounted mini-beam collimator for use at a nominal 6 MV beam energy. Monte Carlo simulation was used in the design and dosimetric characterization of a compact mini-beam collimator assembly mounted to a medical linear accelerator. After fabrication, experimental mini-beam dose profiles and central axis relative output were measured and the results used to validate the simulation data. The simulation data was then used to establish traceability back to an established dosimetric code of practice. The Monte Carlo simulation work revealed that changes in collimator blade width have a greater influence on the valley-to-peak dose ratio than do changes in blade height. There was good agreement between the modeled and measured profile data, with the exception of small differences on either side of the central peak dose. These differences were found to be systematic across all depths and result from limitations associated with the collimator fabrication. Experimental mini-beam relative output and simulation data agreed to better than ± 2.0%, which is well within the level of uncertainty required for dosimetric traceability of non-standard field geometries. A mini-beam collimator has now been designed, built and experimentally characterized for use with a commercial linear accelerator operated at a nominal 6 MV beam energy.

To evaluate and compare in vitro cytotoxicity and corrosion resistance of mini-implants from three different commercial brands used for orthodontic anchorage. Six mini-implants (Conexão(tm), Neodent(tm) and SIN(tm)) were separately immersed in artificial saliva (pH 6.76) for 30 and 60 days. The cytotoxicity of the corrosion extracts was assessed in L929 cell cultures using the violet crystal and MTT assays, as well as cell morphology under light microscopy. Metal surface characteristics before and after immersion in artificial saliva were assessed by means of scanning electron microscopy (SEM). The samples underwent atomic absorption spectrophotometry to determine the concentrations of aluminum and vanadium ions, constituent elements of the alloy that present potential toxicity. For statistical analysis, one-way ANOVA/Bonferroni tests were used for comparisons among groups with p < 0.05 considered significant. Statistical analysis was carried out with Graph Pad PRISM software Version 4.0. No changes in cell viability or morphology were observed. Mini-implants SEM images revealed smooth surfaces with no obvious traces of corrosion. The extracts assessed by means of atomic absorption spectrophotometry presented concentrations of aluminum and vanadium ions below 1.0 µg/mL and 0.5 µg/mL, respectively. Orthodontic mini-implants manufactured by Conexão(tm), Neodent(tm) and SIN(tm) present high corrosion resistance and are not cytotoxic.

The Mini-EUSO project aims to perform observations of the UV-light night emission from Earth. The UV background produced in atmosphere is a key measurement for any experiment aiming at the observation of Extreme Energy Cosmic Rays (EECR) from space, the most energetic component of the cosmic radiation. The Mini-EUSO instrument will be placed within the International Space Station (ISS) in the Russian Module and measures through a UV transparent window. The instrument comprises a compact telescope with a large field of view, based on an optical system employing two Fresnel lenses for increased light collection. The light is focused onto an array of photo-multipliers and the resulting signal is converted into digital, processed and stored via the electronics subsystems on-board. The instrument is designed and built by the members of the JEM-EUSO collaboration. JEM-EUSO is a wide-angle refractive UV telescope being proposed for attachment to the ISS, which has been designed to address basic problems of fundamental physics and high-energy astrophysics investigating the nature of cosmic rays with energies above 10{sup 20} eV. Mini-EUSO will be able to study beside EECRs a wide range of scientific phenomena including atmospheric physics, strange quark matter and bioluminescence. The mission is approved by the Italian Space Agency and the Russian Space Agency. Scientific, technical and programmatic aspects of this project will be described.

Eles são apresentados como "solução" para a maioria dos problemas empresariais. São sistemas genéricos capazes de integrar todas as informações que fluem pela empresa por intermédio de uma base de dados única. A literatura sobre o assunto apresenta uma série de resultados positivos e benefícios a serem obtidos com a adoção desses sistemas. Porém, as dificuldades a serem enfrentadas e a profundidade das mudanças a serem realizadas para a obtenção dos benefícios não são tão claras para as empresas, principalmente para as de pequeno porte, que não possuem tantos recursos para investimento em tecnologia. Este artigo tem por objetivo relatar o resultado de uma pesquisa sobre a adoção de sistemas integrados de gestão, ou ERP, por pequenas empresas, confrontando o referencial teórico e a prática empresarial.In the last years, Enterprise Resource Planning (ERP is being largely used by enterprises. They are presented as "the solution" for the enterprise's problems. They are generic systems able to integrate all the enterprise's informations through a single data base. The literature about this subject presents a series of positive results and benefits a firm could obtain with the systems' adoption. But the difficulties the enterprises face and the deep of changes to be realized for the achievement of the benefits are not clear to the firms, specially for the small businesses which do not have many resources to invest in technology. This paper has the objective to describe the result of a research on the adoption of ERP, by small business, opposing theoretical references and the enterprise practices.

Alcohol Use Disorder (AUD) is associated with problems with processing complex social scenarios. Little is known about the relationship between distinct AUD-related factors (e.g., years of problematic drinking), aspects of cognitive function and dysfunction in individuals diagnosed with AUD, and the relative impact these may have on social cognition. To explore differences in social cognition between a group of participants diagnosed with AUD and controls, using a clinical measure, the Mini Social and Emotional Assessment (mini-SEA). The mini-SEA was used to evaluate social and emotional understanding through a facial emotional recognition task and by utilising a series of social scenes some of which contain a faux pas (social error). Eighty-five participants (individuals with AUD and controls) completed demographic questions and a general cognitive and social cognitive test battery over three consecutive days. Between group analyses revealed that the participants with AUD performed less well on the faux pas test, and differences were also revealed in the emotional facial recognition task. Years of problematic alcohol consumption was the strongest predictor of poor ToM reasoning. These results suggest a strong link between AUD chronicity and social cognition, though the direction of this relationship needs further elucidation. This may be of clinical relevance to abstinence and relapse management, as basic social cognition skills and ability to maintain interpersonal relationships are likely to be crucial to recovery.

We describe the design, implementation, and use of a large, multiorganizational distributed database developed to support the Mini-Sentinel Pilot Program of the US Food and Drug Administration (FDA). As envisioned by the US FDA, this implementation will inform and facilitate the development of an active surveillance system for monitoring the safety of medical products (drugs, biologics, and devices) in the USA. A common data model was designed to address the priorities of the Mini-Sentinel Pilot and to leverage the experience and data of participating organizations and data partners. A review of existing common data models informed the process. Each participating organization designed a process to extract, transform, and load its source data, applying the common data model to create the Mini-Sentinel Distributed Database. Transformed data were characterized and evaluated using a series of programs developed centrally and executed locally by participating organizations. A secure communications portal was designed to facilitate queries of the Mini-Sentinel Distributed Database and transfer of confidential data, analytic tools were developed to facilitate rapid response to common questions, and distributed querying software was implemented to facilitate rapid querying of summary data. As of July 2011, information on 99,260,976 health plan members was included in the Mini-Sentinel Distributed Database. The database includes 316,009,067 person-years of observation time, with members contributing, on average, 27.0 months of observation time. All data partners have successfully executed distributed code and returned findings to the Mini-Sentinel Operations Center. This work demonstrates the feasibility of building a large, multiorganizational distributed data system in which organizations retain possession of their data that are used in an active surveillance system.

2016-09-01

Today׳s most commonly applied bonding effectiveness tests are criticized for their high variability and low reliability, the latter in particular with regard to measuring the actual strength of the adhesive interface. in continuation of previous research conducted at dentin, we hereby aimed to validate the novel mini-interfacial fracture toughness (mini-iFT) test on its applicability to assess bonding effectiveness of contemporary adhesives when bonded to enamel. The 3-step etch&rinse (E&R) adhesive OptiBond FL (Kerr), the 2-step self-etch (SE) adhesive Clearfil SE Bond (Kuraray Noritake) and the two multi-mode adhesives Clearfil S(3) Bond Plus (Kuraray Noritake) and Scotchbond Universal (3M ESPE), both used following a 2-step E&R and 1-step SE mode, were applied to clinically relevant, flattened enamel surfaces. A composite (Filtek Z100; 3M ESPE) build-up was made in layers. After 1-week water storage at 37°C, all specimens were sectioned perpendicular to the interface to obtain rectangular sticks. A mini-iFT notch was prepared at the adhesive-enamel interface using a thin diamond blade under water cooling. Finally, the specimens were loaded in a 4-point bending test until failure. the mini-iFT onto human enamel was significantly higher for the adhesives applied in E&R mode versus those applied in SE mode. The lowest mini-iFT was found for the adhesives applied following a 1-step SE approach. SEM fracture analysis revealed that all fractures originated at the adhesive-enamel interface and that the induced crack propagated preferentially along this interface. mini-iFT appeared a valid alternative method to assess the mechanical properties of adhesive-enamel interfaces.

Schuh, Michael J.; Melton, John E.; Stremel, Paul M.

2017-01-01

It is challenging to review and assimilate large data sets created by Computational Fluid Dynamics (CFD) simulations and wind tunnel tests. Over the past 10 years, NASA Ames Research Center has developed and refined a software tool dubbed the MiniWall to increase productivity in reviewing and understanding large CFD-generated data sets. Under the recent NASA ERA project, the application of the tool expanded to enable rapid comparison of experimental and computational data. The MiniWall software is browser based so that it runs on any computer or device that can display a web page. It can also be used remotely and securely by using web server software such as the Apache HTTP server. The MiniWall software has recently been rewritten and enhanced to make it even easier for analysts to review large data sets and extract knowledge and understanding from these data sets. This paper describes the MiniWall software and demonstrates how the different features are used to review and assimilate large data sets.

The mini LHC Lego project launched in March (see here) now has almost 6,000 supporters - well on its way to the 10,000 votes needed for it to (hopefully!) hit store shelves. This week, the project added a new feature to its line: a mini control centre! The new LEGO Control centre, featuring operators "Kerstin" and "Marco".   The mini LHC project is the brainchild of ATLAS PhD student Nathan Readioff, who designed Lego replicas of the LHC and the ALICE, ATLAS, CMS and LHCb experiments on a micro scale. Each detector model is small enough to fit in the palm of your hand but crammed with detailed internal systems revealed by cutaway walls. Every major detector component is represented by a Lego piece. Now, Nathan has created a control centre to complement the mini LHC project. This would be an add-on feature for Lego’s consideration, should they decide to develop the accelerator into a box set. “The control centre is ...

Lateral forces exerted through ball or bar attachments in relation to the inclination of mini-implant underneath overdentures: in vitro study.

Takagaki, Kyozo; Gonda, Tomoya; Maeda, Yoshinobu

2015-09-01

Lateral force to mini-implants should be avoided because mini-implants are weak mechanically because of its small diameter. Overdentures retained by mini-implants are usually formed using ball attachments. However, bar attachments can offer the advantage of splinting the mini-implants. This study examined the effect of attachments in withstanding these lateral forces in tilted mini-implants of overdentures. Strain gauges were attached to the mini-implants (2.5 × 18 mm) embedded in an acrylic resin block. Two mini-implants were inserted vertically (Control) or with one mini-implant inclined at 10° or 20° (10-inclined and 20-inclined, respectively). The female portions of the attachments were secured to the denture base. A prefabricated ball attachment and CAD/CAM-fabricated bar attachment were compared. A vertical load of 49 N was applied to the occlusal surface at a distance 10 mm away from the center of two mini-implants. The lateral force borne by the mini-implants was measured via the attached strain gauge. Mann-Whitney U-test and an analysis of Bonferroni correction were used to compare differences between the two attachments and among the three models (P < 0.05). The lateral force exerted to the inclined mini-implant was significantly greater than that borne by a vertical mini-implant for both attachment types. The lateral force on the 20° inclined mini-implants with bar attachments was smaller than that on mini-implants with ball attachments. Inclined mini-implants are subjected to greater stresses than vertical ones, and a bar attachment can reduce the lateral forces borne by the mini-implant when one mini-implant inclined at 20°. © 2014 John Wiley & Sons A/S.

Error Correction of Meteorological Data Obtained with Mini-AWSs Based on Machine Learning

Ji-Hun Ha

2018-01-01

Full Text Available Severe weather events occur more frequently due to climate change; therefore, accurate weather forecasts are necessary, in addition to the development of numerical weather prediction (NWP of the past several decades. A method to improve the accuracy of weather forecasts based on NWP is the collection of more meteorological data by reducing the observation interval. However, in many areas, it is economically and locally difficult to collect observation data by installing automatic weather stations (AWSs. We developed a Mini-AWS, much smaller than AWSs, to complement the shortcomings of AWSs. The installation and maintenance costs of Mini-AWSs are lower than those of AWSs; Mini-AWSs have fewer spatial constraints with respect to the installation than AWSs. However, it is necessary to correct the data collected with Mini-AWSs because they might be affected by the external environment depending on the installation area. In this paper, we propose a novel error correction of atmospheric pressure data observed with a Mini-AWS based on machine learning. Using the proposed method, we obtained corrected atmospheric pressure data, reaching the standard of the World Meteorological Organization (WMO; ±0.1 hPa, and confirmed the potential of corrected atmospheric pressure data as an auxiliary resource for AWSs.

ASTRI is a flagship project of the Italian Ministry of Education, University and Research. Within this framework, INAF is currently developing an end-to-end prototype of the CTA small-size telescope in a dual-mirror configuration (SST-2M) to be tested under field conditions, and scheduled to start data acquisition in 2014. A remarkable improvement in terms of performance could come from the operation, in 2016, of a SST-2M mini-array, composed by a few SST-2M telescopes and to be placed at final CTA Southern Site. The SST mini-array will be able to study in great detail relatively bright sources (a few x10E-12 erg/cm2/s at 10 TeV) with an angular resolution of a few arcmin and an energy resolution of about 10 - 15%. Moreover, thanks to the array approach, it will be possible to verify the wide FoV performance to detect very high energy showers with the core located at a distance up to 500 m, to compare the mini-array performance with the Monte Carlo expectations by means of deep observations of few selected targets, and to perform the first CTA science, with its first solid detections during the first year of operation. Prominent sources such as extreme blazars (1ES 0229+200), nearby well-known BL Lac objects (MKN 501) and radio-galaxies, galactic pulsar wind nebulae (Crab Nebula, Vela-X), supernovae remnants (Vela-junior, RX J1713.7-3946) and microquasars (LS 5039), as well as the Galactic Center can be observed in a previously unexplored energy range, in order to investigate the electron acceleration and cooling, relativistic and non relativistic shocks, the search for cosmic-ray (CR) Pevatrons, the study of the CR propagation, and the impact of the extragalactic background light on the spectra of the sources.

Akimoto, Hajime; Abe, Yutaka; Ohnuki, Akira; Murao, Yoshio

1991-05-01

MINI-TRAC code, a driver program for assessment of constitutive equations of two-fluid model, has been developed to perform assessment and improvement of constitutive equations of two-fluid model widely and efficiently. The MINI-TRAC code uses one-dimensional conservation equations for mass, momentum and energy based on the two-fluid model. The code can work on a personal computer because it can be operated with a core memory size less than 640 KB. The MINI-TRAC code includes constitutive equations of TRAC-PF1/MOD1 code, TRAC-BF1 code and RELAP5/MOD2 code. The code is modulated so that one can easily change constitutive equations to perform a test calculation. This report is a manual of the MINI-TRAC code. The basic equations, numerics, constitutive, equations included in the MINI-TRAC code will be described. The user's manual such as input description will be presented. The program structure and contents of main variables will also be mentioned in this report. (author)

A mini-exhibition with maximum content

2011-01-01

The University of Budapest has been hosting a CERN mini-exhibition since 8 May. While smaller than the main travelling exhibition it has a number of major advantages: its compact design alleviates transport difficulties and makes it easier to find suitable venues in the Member States. Its content can be updated almost instantaneously and it will become even more interactive and high-tech as time goes by.   The exhibition on display in Budapest. The purpose of CERN's new mini-exhibition is to be more interactive and easier to install. Due to its size, the main travelling exhibition cannot be moved around quickly, which is why it stays in the same country for 4 to 6 months. But this means a long waiting list for the other Member States. To solve this problem, the Education Group has designed a new exhibition, which is smaller and thus easier to install. Smaller maybe, but no less rich in content, as the new exhibition conveys exactly the same messages as its larger counterpart. However, in the slimm...

Full Text Available Objective: To compare the acceptability and effectiveness of topical and infiltration anesthesia for placement of mini-implants used as temporary anchorage devices. Methods: The sample comprised 40 patients, 17 males and 23 females, whose mean age was 26 years old and who were all undergoing orthodontic treatment and in need for anchorage reinforcement. Mini-implants were bilaterally placed in the maxilla of all individuals, with infiltration anesthesia on one side and topical anesthesia on the other. These 40 patients completed two questionnaires, one before and another after mini-implant placement and pain was measured through a visual analog scale (VAS. The data collected were analyzed using descriptive statistics and the measurements of pain were compared by means of the non-parametric test of Mann-Whitney. Results: It was found that 60% of patients felt more comfortable with the use of topical anesthesia for mini-implant placement; 72.5% of patients described the occurrence of pressure during placement of the anchorage device as the most unpleasant sensation of the entire process; 62.5% of patients felt more pain with the use of topical anesthesia. Conclusion: It was concluded that patients had less pain with the use of infiltration anesthesia, and also preferred this type of anesthetic.

Science.gov (United States)

Hiller, Wolfgang; Goebel, Gerhard

2004-01-01

The aim of this study was to develop an abridged version of the Tinnitus Questionnaire (TQ) to be used as a quick tool for the assessment of tinnitus-related psychological distress. Data from 351 inpatients and 122 outpatients with chronic tinnitus were used to analyse item statistics and psychometric properties. Twelve items with an optimal combination of high item-total correlations, reliability and sensitivity in assessing changes were selected for the Mini-TQ. Correlation with the full TQ was >0.90, and test-retest reliability was 0.89. Validity was confirmed by associations with general psychological symptom patterns. Treatment effects indicated by the Mini-TQ were slightly greater than those indicated by the full TQ. The Mini-TQ is recommended as a psychometrically approved and solid tool for rapid and economical assessment of subjective tinnitus distress.

This study was carried out to evaluate the effect of gamma irradiation on nutrient digestibility of either soy-based or milk-based diet for specific pathogen-free (SPF) mini-pigs. Gamma irradiation of the diets was done at dosage of 10 kGy with {sup 60}Co whereas autoclaving was executed at 121 {sup o}C for 20 min. Apparent crude protein digestibilities of gamma irradiated diets were higher (p<0.05) than those of autoclaved diets regardless of diet type. Digestibilities of dry matter, gross energy and total carbohydrate in the irradiated diet were higher than those of the autoclaved diet. From the results of nutrient digestibility of mini-pig diets in this study, 10 kGy gamma radiation was suggested as a convenient diet radicidation method that can minimize the decrease in nutrient digestibility on feeding to SPF mini-pigs.

Incorporating Inquiry into Upper-Level Homework Assignments: The Mini-Journal

The U.S. National Science Education Standards provide guidelines for teaching science through inquiry, where students actively develop their understanding of science by combining scientific knowledge with reasoning and thinking skills. Inquiry activities include reading scientific literature, generating hypotheses, designing and carrying out investigations, interpreting data, and formulating conclusions. Inquiry-based instruction emphasizes questions, evidence, and explanation, the essential features of inquiry. As part of an NSF-funded project, “CUES: Connecting Undergraduates to the Enterprise of Science,” new inquiry-based homework materials were developed for two upper-level classes at the University of Missouri: Geochemistry (required for Geology majors), and Solar System Science (open to seniors and graduate students, co-taught and cross-listed between Geology and Physics & Astronomy). We engage students in inquiry-based learning by presenting homework exercises as “mini-journal” articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. Mini-journals replace traditional homework problem sets with a format that more directly reflects and encourages scientific practice. Students are engaged in inquiry-based homework which encompass doing, thinking, and communicating, while the minijournal allows the instructor to contain lines of inquiry within the limits posed by available resources. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. The key differences between the old and new formats include (i) the active participation of the students in

Advances in Autonomous Mini Robots : Proceedings of the 6-th AMiRE Symposium

CERN Document Server

Joaquin, Sitte; Felix, Werner

2012-01-01

Autonomous robots must carry out useful tasks all by themselves relying entirely on their own perceptions of their environment. The cognitive abilities required for autonomous action are largely independent of robot size, which makes mini robots attractive as artefacts for research, education and entertainment. Autonomous mini robots must be small enough for experimentation on a desktop or a small laboratory.  They must be easy to carry and safe for interaction with humans. They must not be expensive. Mini robot designers have to work at the leading edge of technology so that their creations can carry out purposeful autonomic action under these constraints. Since 2001 researchers have met every two years for an international symposium to report on the advances achieved in Autonomous Mini  Robots for Research and Edutainment (AMiRE). The AMiRE Symposium is a single track conference that offers ample opportunities for discussion and exchange of ideas. This volume contains the contributed papers of the 2011 AM...

Celha Borges Costa Alves

Full Text Available ABSTRACT Objective: To evaluate and compare in vitro cytotoxicity and corrosion resistance of mini-implants from three different commercial brands used for orthodontic anchorage. Methods: Six mini-implants (Conexão(tm, Neodent(tm and SIN(tm were separately immersed in artificial saliva (pH 6.76 for 30 and 60 days. The cytotoxicity of the corrosion extracts was assessed in L929 cell cultures using the violet crystal and MTT assays, as well as cell morphology under light microscopy. Metal surface characteristics before and after immersion in artificial saliva were assessed by means of scanning electron microscopy (SEM. The samples underwent atomic absorption spectrophotometry to determine the concentrations of aluminum and vanadium ions, constituent elements of the alloy that present potential toxicity. For statistical analysis, one-way ANOVA/Bonferroni tests were used for comparisons among groups with p < 0.05 considered significant. Statistical analysis was carried out with Graph Pad PRISM software Version 4.0. Results: No changes in cell viability or morphology were observed. Mini-implants SEM images revealed smooth surfaces with no obvious traces of corrosion. The extracts assessed by means of atomic absorption spectrophotometry presented concentrations of aluminum and vanadium ions below 1.0 µg/mL and 0.5 µg/mL, respectively. Conclusion: Orthodontic mini-implants manufactured by Conexão(tm, Neodent(tm and SIN(tm present high corrosion resistance and are not cytotoxic.

Before the operation, patients wereexamined endoscopically and a barium swallow was performed. In all 27 patients (100%, the operation was performedelectively laparoscopically. The principle of the operation in all cases was reposition of the stomach into theabdominal cavity, resection of the hernial sac and hiatoplasty. In addition, in 15 patients (56% with reflux symptomsor endoscopic findings of reflux oesophagitis, fundoplication in Nissen’s modification was also performed. Fundopexywas indicated in 12 patients (44%. Results: In all patients (100%, the operation was performed mini-invasively; conversion to an open procedure wasnever necessary. In 3 cases (11%, the left pleural cavity was opened during the operation; this was treated by introducinga chest drain. The operation mortality in the patient set was zero; morbidity was 11%. A year after the operation,patients were re-examined, and follow-up endoscopy and barium swallow were performed. Conclusions: In all patients diagnosed with upside-down stomach, surgical treatment is indicated due to the risk ofdeveloping severe complications. Mini-invasive surgical therapy in the hands of an experienced surgeon is a safe procedurewhich offers patients all the benefits of mini-invasive therapy with promising short- and long-term results.

Canine parvovirus (CPV) is a non-enveloped single stranded DNA virus with an icosahedral capsid. Mini-sequencing based CPV typing was developed earlier to detect and differentiate all the CPV types and FPV in a single reaction. This technique was further evaluated in the present study by performing the mini-sequencing directly from fecal samples which avoided tedious virus isolation steps by cell culture system. Fecal swab samples were collected from 84 dogs with enteritis symptoms, suggestive of parvoviral infection from different locations across India. Seventy six of these samples were positive by PCR; the subsequent mini-sequencing reaction typed 74 of them as type 2a virus, and 2 samples as type 2b. Additionally, 25 of the positive samples were typed by cycle sequencing of PCR products. Direct CPV typing from fecal samples using mini-sequencing showed 100% correlation with CPV typing by cycle sequencing. Moreover, CPV typing was achieved by mini-sequencing even with faintly positive PCR amplicons which was not possible by cycle sequencing. Therefore, the mini-sequencing technique is recommended for regular epidemiological follow up of CPV types, since the technique is rapid, highly sensitive and high capacity method for CPV typing.

The aim of the study was to evaluate validity of the Italian Mini-ICF-APP (Mini-ICF Rating for Limitations of Activities and Participation in Psychological Disorders) in schizophrenia and related disorders. 74 outpatients affected by schizophrenia or schizoaffective disorders attending a University-based community mental health centre were recruited to the study. All participants underwent comprehensive evaluation using standardized instruments to assess clinical, neurocognitive and functional status. Concurrent validity of Mini-ICF-APP was evaluated and compared to severity scores obtained using the Clinical Global Impression-Schizophrenia scale (CGI-SCH), Positive and Negative Syndrome scale (PANSS), Mini Mental State Examination test (MMSE), Brief Assessment of Cognition in Schizophrenia scale (BACS) and Personal and Social Performance scale (PSP). Construct validity was evaluated by comparing scores obtained at Mini-ICF-APP by remitted versus non-remitted patients, and by recovered versus unrecovered patients. Discriminant validity was evaluated comparing scores on Mini-ICF-APP and Subjective Well-being (SWN) scale. the total score and 12 out of the 13 Mini-ICF-APP items correlated significantly with total score at PSP; Mini-ICF-App total score was moreover significantly correlated with total scores at CGI-SCH, PANSS, MMSE, as well as with several BACS items. Total scores obtained at Mini-ICF-APP were significantly higher among remitted and recovered patients. No relevant correlations were found between scores of Mini-ICF-APP and SWN scales. The total score and 12 out of the 13 Mini-ICF-APP items correlated significantly with total score at PSP; Mini-ICF-App total score was moreover significantly correlated with total scores at CGI-SCH, PANSS, MMSE, as well as with several BACS items.

We report analysis of air-blast overpressure measurements from the MINIE2013 explosive experiments. The MINIE2013 experiment involved a series of nearly 70 near-surface (height-ofburst, HOB, ranging from -1 to +4 m) low-yield (W=2-20 kg TNT equivalent) chemical highexplosives tests that were recorded at local distances (230 m – 28.5 km). Many of the W and HOB combinations were repeated, allowing for quantification of the variability in air-blast features and corresponding yield estimates. We measured canonical signal features (peak overpressure, impulse per unit area, and positive pulse duration) from the air-blast data and compared these to existing air-blast models. Peak overpressure measurements showed good agreement with the models at close ranges but tended to attenuate more rapidly at longer range (~ 1 km), which is likely caused by upward refraction of acoustic waves due to a negative vertical gradient of sound speed. We estimated yields of the MINIE2013 explosions using the Integrated Yield Determination Tool (IYDT). Errors of the estimated yields were on average within 30% of the reported yields, and there were no significant differences in the accuracy of the IYDT predictions grouped by yield. IYDT estimates tend to be lower than ground truth yields, possibly because of reduced overpressure amplitudes by upward refraction. Finally, we report preliminary results on a development of a new parameterized air-blast waveform.

Cognitive impairment, such as dementia, has emerged as the leading public health problem among the elderly. Therefore, early detection of the disorder and providing appropriate healthcare and management is important, particularly, for the patients with comorbid diabetes who require long-term treatment strategies. In Thailand, because of a large number of elderly patients with diabetes, and time constraints in primary care settings, a short and effective cognitive screening test is required. The Mini-Cog is a short and valid cognitive screening test that was specifically designed for use in primary care settings. The present study translated the English language version into a Thai language version, and then measured the interrater reliability and concurrent validity. The processes of cross-language translation were carried out to develop a Thai language version of the Mini-Cog. A total of 21 Thai older adults with type 2 diabetes with a mean aged of 69 ± 7 years were recruited into a study investigating the interrater reliability and concurrent validity of the Mini-Cog Thai version in one primary care center in Thailand. The Mini-Cog Thai version showed a good interrater reliability (K = 0.80, P validity (r = 0.47, P = 0.007, 95% CI 0.37,0.55) with the Mini-Mental State Examination Thai 2002. The findings show that the Thai version of the Mini-Cog is a reliable, performance-based tool in the screening for cognitive function in primary care settings in Thailand. It is recommended that it could be used as a new cognitive screening test for the aging population in the Thai community. © 2014 Japan Geriatrics Society.

This study aimed at establishing the validity and reliability of an English language version of the Mini-ICF-APP. One hundred and five patients under the care of secondary mental health care services were assessed using the Mini-ICF-APP and several well-established measures of functioning and symptom severity. 47 (45 %) patients were interviewed on two occasions to ascertain test-retest reliability and 50 (48 %) were interviewed by two researchers simultaneously to determine the instrument's inter-rater reliability. Occupational and sick leave status were also recorded to assess construct validity. The Mini-ICF-APP was found to have substantial internal consistency (Chronbach's α 0.869-0.912) and all 13 items correlated highly with the total score. Analysis also showed that the Mini-ICF-APP had good test-retest (ICC 0.832) and inter-rater (ICC 0.886) reliability. No statistically significant association with length of sick leave was found, but the unemployed scored higher on the Mini ICF-APP than those in employment (mean 18.4, SD 9.1 vs. 9.4, SD 6.4, p Mini-ICF-APP correlated highly with the other measures of illness severity and functioning considered in the study. The English version of the Mini-ICF-APP is a reliable and valid measure of disorders of capacity as defined by the International Classification of Functioning. Further work is necessary to establish whether the scale could be divided into sub scales which would allow the instrument to more sensitively measure an individual's specific impairments.

Introducing a Low-Cost Mini-Uav for - and Multispectral-Imaging

Bendig, J.; Bolten, A.; Bareth, G.

2012-07-01

The trend to minimize electronic devices also accounts for Unmanned Airborne Vehicles (UAVs) as well as for sensor technologies and imaging devices. Consequently, it is not surprising that UAVs are already part of our daily life and the current pace of development will increase civil applications. A well known and already wide spread example is the so called flying video game based on Parrot's AR.Drone which is remotely controlled by an iPod, iPhone, or iPad (http://ardrone.parrot.com). The latter can be considered as a low-weight and low-cost Mini-UAV. In this contribution a Mini-UAV is considered to weigh less than 5 kg and is being able to carry 0.2 kg to 1.5 kg of sensor payload. While up to now Mini-UAVs like Parrot's AR.Drone are mainly equipped with RGB cameras for videotaping or imaging, the development of such carriage systems clearly also goes to multi-sensor platforms like the ones introduced for larger UAVs (5 to 20 kg) by Jaakkolla et al. (2010) for forestry applications or by Berni et al. (2009) for agricultural applications. The problem when designing a Mini-UAV for multi-sensor imaging is the limitation of payload of up to 1.5 kg and a total weight of the whole system below 5 kg. Consequently, the Mini-UAV without sensors but including navigation system and GPS sensors must weigh less than 3.5 kg. A Mini-UAV system with these characteristics is HiSystems' MK-Okto (www.mikrokopter.de). Total weight including battery without sensors is less than 2.5 kg. Payload of a MK-Okto is approx. 1 kg and maximum speed is around 30 km/h. The MK-Okto can be operated up to a wind speed of less than 19 km/h which corresponds to Beaufort scale number 3 for wind speed. In our study, the MK-Okto is equipped with a handheld low-weight NEC F30IS thermal imaging system. The F30IS which was developed for veterinary applications, covers 8 to 13 μm, weighs only 300 g, and is capturing the temperature range between -20 °C and 100 °C. Flying at a height of 100 m, the camera

Full Text Available O autismo é um distúrbio do desenvolvimento (early-onset marcado por atrasos e desvios nas áreas social, de comunicação e nas habilidades para o jogo (play skills, assim como padrões repetitivos e limitados de interesse e comportamento. Consideráveis evidências empíricas acumuladas nos últimos 5 a 10 anos sugerem que, em geral, quanto mais precoce for a intervenção adequada em crianças autistas, é mais provável maximizar o potencial da criança obtendo melhores resultados. Estes resultados destacam a necessidade de realizar avaliações amplas das deficiências no desenvolvimento nos primeiros anos de vida. Este artigo fornece uma visão geral sobre os princípios e elementos para avaliar crianças pequenas com suspeita de autismo partindo de uma abordagem desenvolvimental ampla na qual os padrões normais de desenvolvimento - paticularmente nos domínios social e de comunicação - sejam a estrutura para compreender os atrasos e desvios na socilaização evidenciados em crianças pequenas com autismo. Também se oferece uma breve síntese das futuras diretrizes para a avaliação dos padrões de socialização em bebês e crianças pequenas que pode aproveitar os avanços tecnológicos atuais que estão surgindo nos estudos de mecanismos básicos de orientação social

To evaluate safety and efficacy of minipercutaneous nephrolithotomy (Mini-PNL) in management of stones in different types of renal anomalies. Patients with stones ≥2 cm or SWL-resistant stones in anomalous-kidneys treated by Mini-PNL between March 2010 and September 2012 were included prospectively. Mini-PNL was done under regional anesthesia in prone position with fluoroscopic guidance through 18 Fr sheath using semirigid ureteroscope (8.5/11.5 Fr) and pneumatic lithotripter. All patients were followed-up for 2-3 years. Stone-free rate was defined as absence of residual fragments ≥2 mm. Student-T, Mann-Whitney, Chi square (χ 2 ), Fisher-exact, one way ANOVA or Kruskal-Wallis test were used for analysis. Mini-PNL was performed for 59 patients (20 horseshoe, 15 malrotated, 7 polycystic, 13 duplex and 4 ectopic pelvic-kidneys). Mean age was 40.18 ± 12.75 (14-78) years. Mean stone burden was 31.72 ± 21.43 (7.85-141.3) mm 2 . Two tracts were required in 7 (11.9 %) patients. Tubeless Mini-PNL with double-J insertion was performed in all patients except two. Operative time was 50.17 ± 18.73 (15-105) min. Hemoglobin loss was 0.44 ± 0.30 (0-1.4) g/dL. Complications were reported in 15 (25.4 %) patients. No pleural injury, sepsis, perinephric-collection or renal-pelvis perforation were reported. Stone-free rate was 89.8 % (converted to open-surgery in one patient, second-look PNL in two patients, auxiliary SWL in three patients). Stone-free rate improved to 98.3 % after retreatment and auxiliary SWL. Site of puncture was mostly upper calyceal in horseshoe-kidney (80 %), mid calyceal in polycystic-kidney (85.7 %) and lower calyceal in duplex-kidney (46.2 %). Punctures were also significantly infracostal in horseshoe-kidney (100 %) and supracostal in both duplex (53.8 %) and malrotated-kidneys (66.7 %). Mini-PNL is safe for management of stones in anomalous-kidney with SFR comparable to standard-PNL but with less complications.

To compare the outcome of mini-percutaneous nephrolithotomy (Mini-PNL) versus standard-PNL for renal stones. Retrospective study was performed between March 2010 and May 2013 for patients treated by Mini-PNL or standard-PNL through 18 and 30 Fr tracts, respectively, using pneumatic lithotripsy. Semirigid ureteroscope (8.5/11.5 Fr) was used for Mini-PNL and 24 Fr nephroscope for standard-PNL. Both groups were compared in stone free rate(SFR), complications and operative time using Student-t, Mann-Whitney, Chi square or Fisher's exact tests as appropriate in addition to logistic regression analysis. P PNL (378) and standard-PNL (151) were nearly comparable in patients and stones criteria including stone burden (3.77 ± 2.21 vs 3.77 ± 2.43 cm 2 ; respectively). There was no significant difference in number of tracts or supracostal puncture. Mini-PNL had longer operative time (68.6 ± 29.09 vs 60.49 ± 11.38 min; p = 0.434), significantly shorter hospital stay (2.43 ± 1.46 vs 4.29 ± 1.28 days) and significantly higher rate of tubeless PNL (75.1 vs 4.6%). Complications were significantly higher in standard-PNL (7.9 vs 20.5%; p PNL (89.9 vs 96%; p = 0.022). This significant difference was found with multiple stones and large stone burden (> 2 cm 2 ), but the SFR was comparable between both groups with single stone or stone burden ≤ 2 cm. Logistic regression analysis confirmed significantly higher complications and SFR with standard-PNL but with significantly shorter operative time. Mini-PNL has significantly lower SFR when compared to standard-PNL (but clinically comparable) with markedly reduced complications and hospital stay. Most of cases can be performed tubeless. The significant difference in SFR was found with multiple stones or large stone burden (> 2 cm 2 ), but not with single stones or stone burden ≤ 2 cm 2 .

Playing Around in the Solar System: Mini-games for Many Missions

Several NASA solar system missions will have major milestones during 2011, the Year of the Solar System. These events include launches, encounters, and orbit insertions. Other missions will continue the explorations already underway. The “Year of the Solar System Game” on The Space Place website (http://spaceplace.nasa.gov/en/kids/solar-system) brings all these efforts together in the context of the whole solar system. The game helps to build awareness of the characteristics of our solar system and some of the missions that are continuing to advance our knowledge and understanding. It is one of many educational tools being developed and deployed for the Year of the Solar System. The game is a “super-game” that encompasses a number of mission-related “mini-games.” The mini-games can be played individually, and they all contribute toward achievements in the super-game. The enveloping interface for all the games is an animated solar system. The player clicks on a planet or a moon, sees a close-up image, and reads a short paragraph about the object. If the object has been endowed with a mission mini-game, player can click on the tiny spacecraft, read about the mission, then play the game—or, if impatient, just immediately play the game (and read about the mission later, we hope). A score “page” keeps track of the player’s achievements and scores. Players earn achievements by reading about the planets, moons, asteroids, comets, and missions and by playing the mission mini-games. The game targets upper elementary age children, as does the entire Space Place website. Each mini-game, although simple, incorporates elements of the spacecrafts’ missions and their target objects. For example, in Cassini Commander, the player must navigate the Cassini spacecraft through gaps in Saturn’s rings and around Saturn’s moons. The super-game is designed to accommodate any number of mission mini-games, so we are hoping to continue to add missions and increase

The Social Phobia Inventory (SPIN) is a widely used measure in mental health settings and a 3-item version (mini-SPIN) has been developed as a screening instrument for social anxiety disorder. In the present study, we examined the psychometric properties of the SPIN and developed a brief version (mini-SPIN-R) designed to assess social anxiety severity using item response theory. Our sample included 569 individuals with social anxiety disorder who participated in 2 clinical trials and filled out a battery of self-report measures. Using a nonparametric kernel smoothing method we identified the most sensitive items of the SPIN. These 3 items comprised the mini-SPIN-R, which was found to have greater internal consistency, and to capture a greater range of symptoms compared to the mini-SPIN. The mini-SPIN-R evidenced superior convergent validity compared to the mini-SPIN and both measures had similar divergent validity. Thus, the mini-SPIN-R is a promising brief measure of social anxiety severity. Copyright © 2013. Published by Elsevier Ltd.

The antigenic types of canine parvovirus (CPV) are defined based on differences in the amino acids of the major capsid protein VP2. Type specificity is conferred by a limited number of amino acid changes and in particular by few nucleotide substitutions. PCR based methods are not particularly suitable for typing circulating variants which differ in a few specific nucleotide substitutions. Assays for determining SNPs can detect efficiently nucleotide substitutions and can thus be adapted to identify CPV types. In the present study, CPV typing was performed by single nucleotide extension using the mini-sequencing technique. A mini-sequencing signature was established for all the four CPV types (CPV2, 2a, 2b and 2c) and feline panleukopenia virus. The CPV typing using the mini-sequencing reaction was performed for 13 CPV field isolates and the two vaccine strains available in our repository. All the isolates had been typed earlier by full-length sequencing of the VP2 gene. The typing results obtained from mini-sequencing matched completely with that of sequencing. Typing could be achieved with less than 100 copies of standard plasmid DNA constructs or ≤10¹ FAID₅₀ of virus by mini-sequencing technique. The technique was also efficient for detecting multiple types in mixed infections. Copyright © 2012 Elsevier B.V. All rights reserved.

2018-02-01

The goal of the work described in this publication was to evaluate a new, small, material-sparing freeze dryer, denoted as the "mini-freeze dryer or mini-FD", capable of reproducing the product temperature history of larger freeze dryers, thereby facilitating scale-up. The mini-FD wall temperatures can be controlled to mimic loading procedures and dryer process characteristics of larger dryers. The mini-FD is equipped with a tunable diode laser absorption spectroscopy (TDLAS) water vapor mass flow monitor and with other advanced process analytical technology (PAT) sensors. Drying experiments were performed to demonstrate scalability to larger freeze dryers, including the determination of vial heat transfer coefficients, K v . Product temperature histories during K v runs were evaluated and compared with those obtained with a commercial laboratory-scale freeze dryer (LyoStar II) for sucrose and mannitol product formulations. When the mini-FD wall temperature was set at the LyoStar II band temperature (- 20°C) to mimic lab dryer edge vials, edge vial drying in the mini-FD possessed an average K v within 5% of those obtained during drying in the LyoStar II. When the wall temperature of the mini-FD was set equal to the central vial product temperature, edge vials behaved as center vials, possessing a K v value within 5% of those measured in the LyoStar II. During both K v runs and complete product freeze drying runs, the temperature-time profiles for the average edge vials and central vial in the mini-FD agreed well with the average edge and average central vials of the LyoStar II.

A invasão extensa dos gânglios mediastínicos pelo carcinoma de pequenas células do pulmão é ocorrência frequente.Rev Port Pneumol 2010; XVI (4: 659-670 Abstract: Based on a case of gastric antral vascular ectasia (watermelon stomach that was associated with hemorrhagic pericarditis, small cell lung carcinoma with mediastinal lymph node metastases and a synchronous squamous cell carcinoma of the base of the tongue, the authors made a review of the clinical, endoscopic and histopathological aspects of this type of gastropathy, and its association with other diseases, and of the results of its endoscopic therapy. The causes of hemorrhagic pericarditis are considered, emphasizing the necessity to know if the effusion has a malignant etiology. To the best of our knowledge the association of watermelon stomach to small cell lung carcinoma and squamous cell carcinoma of the base of the tongue has not yet been described. Extensive metastases to mediastal lymph nodes are common to small cell lung carcinoma.Rev Port Pneumol 2010; XVI (4: 659-670 Palavras-chave: Gastropatia antral com ectasia vascular, est

Full Text Available O presente trabalho teve por objetivo avaliar a variabilidade espacial da sodicidade do solo em rampas cultivadas com Brachiaria humidicula e Zoysia japonica para tratamento de esgoto sanitário. Na estação de tratamento de esgoto do município de Januária/MG foram coletadas amostras de solo em duas rampas de tratamento de esgoto, uma cultivada com Brachiaria humidicula (RCBH e outra cultivada com Zoysia japonica (RCZJ. Foram realizadas análises de químicas do solo e com isso determinou-se a Razão de Adsorção de Sódio (RAS e a Porcentagem de Sódio Trocável (PST. Os dados foram submetidos à geoestatística. As maiores variabilidades foram observadas para a RAS e PST da RCBH, sendo classificadas como elevadas. Na análise da dependência espacial foi possivel observar que as variáveis estudadas apresentam forte correlação espacial, com excessão da RAS obtida da RCZJ que é considerada de fraca. Apesar da alta variabilidade espacial, a amplitude dos valores de RAS e PST encontrados nas rampas são pequenas não apresentando grandes riscos a salinização do solo a curto prazo.

We have compiled a sample of 14 of the optically brightest radio-quiet quasars (m i ≤ 17.5 and z ≥ 1.9) in the Sloan Digital Sky Survey Data Release 5 quasar catalog that have C IV mini-broad absorption lines (mini-BALs) present in their spectra. X-ray data for 12 of the objects were obtained via a Chandra snapshot survey using ACIS-S, while data for the other two quasars were obtained from archival XMM-Newton observations. Joint X-ray spectral analysis shows that the mini-BAL quasars have a similar average power-law photon index (Γ ∼ 1.9) and level of intrinsic absorption (N H ∼ 21 cm -2 ) as non-BMB (neither BAL nor mini-BAL) quasars. Mini-BAL quasars are more similar to non-BMB quasars than to BAL quasars in their distribution of relative X-ray brightness (assessed with Δα ox ). Relative colors indicate mild dust reddening in the optical spectra of mini-BAL quasars. Significant correlations between Δα ox and UV absorption properties are confirmed for a sample of 56 sources combining mini-BAL and BAL quasars with high signal-to-noise ratio rest-frame UV spectra, which generally supports models in which X-ray absorption is important in enabling driving of the UV absorption-line wind. We also propose alternative parameterizations of the UV absorption properties of mini-BAL and BAL quasars, which may better describe the broad absorption troughs in some respects.

A produção hidro-eléctrica distribuída, em centrais mini ou micro-hídricas, é um modelo interessante, e por vezes imperioso, de produção de energia num contexto em que se impõe a minimização dos impactos, sobre ecossistemas e populações, dos empreendimentos projectados para responder a crescente procura energética. O reconhecimento do potencial para a produção hidro-eléctrica numa região requer informação de natureza topográfica e hidrológica, esta com extensão temporal garantindo fiabilidade...
