    Full Text Available La inversión materna es un importante determinante del peso al nacer. En poblaciones con fecundidad natural, esta inversión afectaría negativamente la propia condición física de la madre a medida que aumenta su edad y paridad. Estudios realizados en una población rural Toba del oeste formoseño indicaron un aumento de la masa corporal materna con la edad y un elevado porcentaje de mujeres con sobrepeso y obesidad. ¿Se traslada este aumento en las reservas energéticas maternas al peso al nacer de sus hijos? El objetivo de este trabajo fue analizar el peso al nacer de esta población aborigen en relación a la edad materna y el sexo del recién nacido. Los datos fueron tomados de registros de agentes sanitarios Toba y de la sala médica. Se analizaron 528 nacimientos (253 femeninos y 275 masculinos desde el año 1983 al 2007. El peso al nacer mostró una asociación positiva estadísticamente significativa con la edad de la madre. Estos resultados confirmarían la condición física materna como un importante predictor del peso al nacer. Sin embargo, no se encontraron diferencias sexuales en el peso al nacer. Se hipotetiza una mayor inversión materna hacia las hijas como parte de la estrategia reproductiva materna.

    Full Text Available O Centro-Oeste brasileiro se destaca no setor agrícola por ser uma das principais regiões produtoras e exportadoras de grãos. O objetivo central desse trabalho foi fazer uma caracterização da exportação dos produtos do complexo soja na região Centro-Oeste. Além disso, buscou-se analisar a importância desses produtos para a região. Os dados utilizados nesta pesquisa referem-se à exportação dos produtos do complexo soja na região e no Brasil, oriundos do Sistema de Análise Exterior (ALICE, da Secretaria de Comércio Exterior (SECEX e do World Trade Organization (WTO. Como método de pesquisa, utilizou-se primeiramente o Índice de Vantagem Comparativa Revelada (IVCR, porém, como esse índice apresenta valores positivos assimétricos, recorreu-se ao Índice de Vantagem Comparativa Revelada Simétrica (IVCRS, a fim de suprir essa limitação, pois os valores do IVCRS variam entre -1 e 1. Como resultado constatou-se que a região Centro-Oeste apresenta vantagens comparativas na exportação do complexo soja, porém essa vantagem vem apresentando queda nos últimos anos.

    1992-09-01

    Road development and colonization projects have brought about wide-scale deforestation in the Brazilian Amazon. The state of Rondonia, located in the western Amazon Basin, best exemplifies the problems related to land-use changes because it has the highest rates of deforestation in the Amazon Basin. In order to identify the main land-use practices in Rondonia, interviews with local farmers were carried out in the central part of Rondonia, in the PIC (Integrated Colonization Project) Ouro Preto do Oeste. This is the oldest colonization project in the state. The governmental colonization programs attracted migrants to the area through the construction of roads and infrastructure necessary for the colonists to occupy the land for agricultural practices. The interviews were done on lots of the PIC Ouro Preto and in PAD Urupa to define the background of the colonists, their land-use practices, their economic situation, and their relationships with governmental institutions.

    Full Text Available Endomarketing ou marketing interno são ações de Marketing voltadas para o público interno das empresas. O artigo que se apresenta a seguir foi baseado em uma pesquisa de campo financiada pelo Projeto PIC SENAC realizada na cidade de São Miguel do Oeste/SC, no ano de 2010, onde, em um primeiro momento, pesquisou-se os gestores das empresas que eram associados à Câmara de Dirigentes Lojistas naquele ano. Com os rumos daquela pesquisa, buscou-se, no ano de 2011, trabalhar uma segunda etapa, desta vez, pesquisando os funcionários das empresas cadastradas na Câmara de Dirigentes Lojistas (CDL da mesma cidade. Os pesquisadores procuraram identificar o grau de uso de algumas ferramentas do Endomarketing nas empresas da referida cidade, na visão dos funcionários. Neste estudo, trabalhamos com pesquisa bibliográfica e exploratória. A partir deste estudo, buscamos cruzar alguns dados a fim de diagnosticar se realmente as informações apresentadas pelos gestores no ano de 2010 condiziam com a visão dos funcionários na etapa de 2011. Percebemos com esta pesquisa que o uso de algumas ferramentas do endomarketing por parte das empresas de São Miguel do Oeste ainda é pequeno. Também constatamos, ao longo deste estudo, que trabalhar o capital humano dentro das organizações trará resultados positivos para elas, pois, quando os funcionários estão motivados, certamente seus trabalhos refletem no público externo (consumidores das empresas.

    Full Text Available La existencia de flujos de agua subterránea en un macizo rocoso muy agrietado, unido a un relieve favorable al escurrimiento superficial, facilita la infiltración del agua hacia el interior de los túneles, laboreados al nivel del manto freático o por debajo de éste, en el Trasvase Este-Oeste que se construye en la provincia de Holguín, Cuba. Como consecuencia, se producen inundaciones arciales y derrumbes por la pérdida de resistencia de las rocas o por el lavado del relleno de las grietas. Para adoptar medidas correctoras que aumenten la seguridad de las excavaciones y garanticen una mayor estabilidad de las obras es necesaria la delimitación de las áreas susceptibles a inundaciones y derrumbes por infiltración del agua. Mediante la combinación de métodos geomecánicos de análisis de macizos, estudios hidrogeológicos y cartografía digital se delimitaron, para el túnel Serones-Salida Guaro, cuatro zonas muy susceptibles por infiltración atendiendo a su alta permeabilidad (más de 10 m/día y a su ubicación en la intersección de dos sistemas de fallas donde han ocurrido movimientos rumbo-deslizantes.

    Full Text Available Este artigo objetiva identificar e analisar as ações, o perfil e as características intraempreendedoras dos gestores de cursos de graduação em Ciências Contábeis do oeste do Paraná. Assim, a questão de pesquisa formulada foi: Quais são as características intraempreendedoras e as principais ações dos gestores de cursos de Ciências Contábeis da região oeste do Paraná? Utilizou-se como método a pesquisa descritiva do tipo survey e, para coleta de dados, um questionário de Mastella (2005 e de Dornelas (2003, adaptado por Walter et al. (2007. Como principais resultados, constatou-se que os gestores são homens, tendo a maioria mais de 50 anos, titulação de especialista ou mestre e o principal vínculo com a instituição na qual atuam. Percebeu-se que as ações mais desenvolvidas pelos gestores apresentam-se voltadas às ações internas, fato que deveria ser objeto de reflexão, uma vez que ações consideradas mais importantes pelos gestores são menos realizadas. Assim, pouco tempo de dedicação à gestão, discrepâncias entre ações desejadas e efetivamente realizadas e demasiado enfoque interno de suas ações são aspectos a serem melhorados pelos gestores investigados. Todos os respondentes apresentam características intraempreendedoras. Percebe-se a necessidade de maior clareza no diálogo entre os superiores e os gestores para um maior alinhamento em relação ao desempenho atual dos gestores. Nota-se também que questões como a conciliação entre a carga horária ensino/gestão ainda precisa ser aperfeiçoada.

    Full Text Available ResumoConciliar a conservação de florestas nativas e a produção agropecuária em estabelecimentos rurais é uma tarefa complexa que demanda abordagens sistêmicas e multidisciplinares que incluam, além de aspectos biológicos dos recursos, outros de natureza socioeconômica, cultural e mesmo psicológica. Para identificar e comparar a intenção comportamental de agricultores da região Oeste de Santa Catarina para a conservação e manejo de florestas nativas em seus imóveis rurais, foi utilizada neste trabalho a Teoria do Comportamento Planejado. Verificou-se que a Intenção Comportamental de agricultores de diferentes sistemas de produção e de agricultores com e sem dependência por recursos florestais nativos para compor a renda, diferem. Diferenças entre grupos de agricultores em relação aos resultados da Atitude e do Controle Comportamental Percebido estavam associadas de forma coerente com aspectos socioeconômicos e ambientais. Os resultados das Normas Subjetivas indicam que a família é a principal referência dos agricultores, exercendo pressão positiva para a conservação florestal.

    Full Text Available Clinical or sub-clinical mastitis are the main illnesses that affect dairy herds, with impact on the economy, the industry, and with consequence to public health. Considering that the city of Santa Izabel do Oeste is located in the second bigger milk region of Paraná state, and that mastitis cases are epidemiologically classified as ambient or contagious, the purpose of this study was to identify possible etiologic agents of bovine mastitis, by the use of a preliminary, fast and cheap diagnostic method to differentiate these types of illness, to orient treatment and prophylactic measures. Two triplates were employed. Triplate I was composed by blood agar, bile-esculine agar and mannitol-salt agar, while triplate II was composed by MacConkey agar; Baird-Parker agar and sabouraud-dextrose agar with cloranfenicol. Additionally, a tube with sabouraud-dextrose agar with cloranfenicol incubated at room temperature temperature was used for the research of filamentous moulds. It was observed that the great majority of the isolated samples had Staphylococcus coagulase negative, coliforms, Staphylococcus aureus, no-fermenters bacilli gram negative, Coryneforms, Streptococcus spp. and Streptococcus agalactiae.

    Full Text Available RESUMEN En el extremo oeste de la provincia de La Pampa persisten prácticas culturales, productivas y vinculares arraigadas desde comienzos del siglo XX. Dentro de los agentes tradicionales que históricamente han interactuado con los productores del área, se destacan los vendedores ambulantes o mercachifles. A través de densas redes, éstos han proveído a los productores de bienes de consumo. En el artículo se pretenden explorar los vínculos históricos establecidos entre los vendedores ambulantes y los campesinos, las trayectorias y estrategias comerciales gestadas en el pasado y en el presente. Las relaciones entre los mercachifles y los intermediarios con los productores, se estudian a través de testimonios y el cruce de datos obtenidos en el trabajo de gabinete y de campo en Chos Malal y La Humada. Finalmente se reflexiona sobre los factores que posibilitan la persistencia de ciertas relaciones de subordinación entre comerciantes y productores que habitan en parajes rurales. ABSTRACT In the far west of the province of La Pampa persist cultural, productive and relational practices rooted from the early twentieth century. Among the traditional agents that have historically interacted with area producers stand street vendors or hawkers. Through these dense networks they have provided to producers of consumer goods. In the article aims to explore the established historical ties between street vendors and farmers, paths and business strategies engendered in the past and in the present. Relations between peddlers and producers intermediaries are studied through testimonials and crossing data obtained in office work and field in Chos Malal and the Humada. Finally we examine the factors that make the persistence of certain reporting relationships between traders and farmers who live in rural places.

    Full Text Available O objetivo deste artigo é publicizar parte de minha tese de doutorado. Essa tese teve por objetivo geral analisar e compreender a gênese do cooperativismo agropecuário da mesorregião Oeste paranaense a partir da cultura associativa de seus fundadores. Para este artigo abordou-se: a parte do referencial teórico pautado no conceito da cultura associativa e; b no quadro de análise pautado no processo de formação e colonização da mesorregião Oeste paranaense, seguido do processo histórico de fundação das cooperativas agropecuárias selecionadas: Copacol, C.Vale, Lar, Coopavel e Copagril. A metodologia adotada partiu da abordagem qualitativa, a partir da premissa descritivo-explicativa.  Como fonte de dados utilizou-se dados secundários. Como resultado constatou-se que a gênese das cooperativas em estudo se deu em função das necessidades sociais dos sujeitos, dos colonos que as fundaram. A cultura associativa resgatada por meio das memórias desses colonos tornou-se o marco cultural, mantido e reproduzido pela estrutura comunitária desses colonos. A dinâmica de convivência coletiva e as relações comunitárias mantiveram-se independentes das mudanças macroeconômicas do país. Foi esse espírito gregário, entranhado na estrutura social dos migrantes que colonizaram a mesorregião Oeste paranaense, o norteador das iniciativas de cooperação que desencadearam nas associações de produtores, e essas, nas cooperativas agropecuárias em estudo.

    Full Text Available A história de uma quadrilha de bandidos calabreses no município de São Carlos, oeste paulista, ao final do século XIX permitiu-nos investigar por que o banditismo italiano era raro no Brasil. A quadrilha contou com certa rede de apoio entre calabreses e com o silêncio de outros italianos, seja pela intimidação, seja pela desconfiança que estes nutriam das autoridades brasileiras. Uma epidemia devastadora de febre amarela, que afastou da região grande parte da elite local e debilitou a polícia, garantiu ao bando alguns anos de impunidade. O fato de terem imigrado para a região italianos de várias origens não é suficiente para explicar a raridade do banditismo e do crime organizado entre italianos no Brasil. Dois fatores foram decisivos nesse sentido, ao contrário do que ocorreu na Calábria e nos Estados Unidos: ausência de elites dispostas a proteger bandidos imigrantes e dificuldade para os bandidos corromperem as autoridades locais, especialmente a polícia.

A metodologia utilizada foi o estudo de caso, e as informações analisadas foram obtidas através de pesquisa de campo junto a atores estratégicos envolvidos na produção de leite e derivados na região. Concluiu-se que a IN51 influencia decisivamente a forma de organização e participação da agricultura familiar na cadeia produtiva do leite.This paper aims to analyze how family farmers behave facing significant changes in the institutional environment of milk production chain. In this sense, we investigated main consequences and impacts on the social and productive organization of milk producing families as a result of the Institution Normative 51 by Ministry of Agriculture in the western region of Santa Catarina state. We used the approach of New Institutional Economics (NIE and field research with strategic actors involved in the dairy production in the region. We concluded that the IN51 decisively influences the form of organization and participation of family farming in the milk production chain.

    Full Text Available El objetivo de este artículo es comparar y contrastar algunos conjuntos de vivienda modernos en ciudades europeas del Oeste (“capitalistas” y del Este (“socialistas”. Nuestro trabajo se centra en conjuntos de vivienda masiva construidos en el periodo de crecimiento urbano acelerado que tuvo lugar en Europa principalmente en las décadas de los años 60 y 70 del pasado siglo. El punto de partida más obvio es que las ciudades socialistas son diferentes de las europeas occidentales por la distinta naturaleza de sus políticas urbanas, el sistema de planificación económica socialista centralizada, la ausencia de un mercado del suelo libre, el impacto de la industrial­ización en el sector de la construcción, etc. Sin embargo, hay muchos conceptos en urbanismo, así como en los procesos urbanos, que fueron compartidos en ambos sistemas políticos e ideológicos. El artículo ofrece una perspectiva comparada de la naturaleza de esos conjuntos residenciales modernos construidos a ambos lados del Telón de Acero –Housing Es­tates en UK, Grands Ensembles en Francia, Großsiedlungen en Alemania, Polígonos en España o los grandes conjuntos residenciales socialistas en los países del Bloque del Este– con el fin de entender mejor si –y hasta qué punto– las formas urbanas de dichos conjuntos son el resultado de la cultura internacional del urbanismo moderno.

Objetivou investigar de que forma a LAI é disponibilizada nas prefeituras catarinenses integrantes da Associação dos Municípios do Extremo Oeste de Santa Catarina (AMEOSC. Trata-se de uma pesquisa descritiva, documental e quantitativa. Utilizou checklist e questionário aplicado às 13 prefeituras da AMEOSC, que formaram o universo desta pesquisa. Fundamentou-se a revisão de literatura abordando sobre a LAI, a gestão documental arquivística e os ciclos de vida dos documentos. Dos 13 questionários aplicados, responderam seis prefeituras, (três possuem população acima de dez mil, obrigadas a disponibilizar o acesso à LAI e três abaixo de dez mil. Conclui-se que é cedo para fazer uma ampla avaliação da disponibilização da LAI nos municípios pesquisados, visto que a mesma foi aprovada em 2011. As prefeituras estão se estruturando para atender as demandas. Considerou-se como obstáculos a insuficiência de recursos humanos, inadequada divulgação e conscientização dos servidores e da população em geral.

This activity was developed during the IX Environmental Week, an event that took place at Campus in June, 2016. During the activity, the academics in Biological Sciences course carried out mini-courses in which was approached the subject of human sexuality for four classes from the first year students in Agricultural Technical Course integrated to High School. After completing the activities of Sexual Education that dealt with some topics such as: early sexual initiation, STIs (sexually transmitted infections, homophobia, sexual harassment, media exposure, gender difference, contraceptive methods, among others and after all the data were collected. For that, the students answered a questionnaire about the subject on sexuality, the contributions of this practice is in order to discuss situations related to the subject. After the analysis, was checked a great relevance of the theme proposed for the initial qualification of academics in order to them approach the subject in a significant way to teenagers who attend the schools in which these academics will be able to develop their activities. It was checked out that students from the Agricultural Course integrated to High School who was developing the course have a very restricted index of information about the subject that was handled it. This can be a reality that reaches many young people who attend the Basic Education in many Brazilian schools. On the other hand, the information obtained gave the academics and teachers from the Biological Sciences Course moments of reflection about the inclusion of contents that contemplate this subject in the school curriculum of Basic Education and of the higher course that they attend, as well as the need of a

    Full Text Available La prevalencia sobrepeso y obesidad ha estado aumentando significativamente en los últimos años, aún en poblaciones socioeconómicamente carenciadas. Las poblaciones indígenas parecen ser particularmente susceptibles a este factor de riesgo, aunque las razones para esto no son claras. El objetivo de este trabajo fue el de analizar la prevalencia de sobrepeso y obesidad en una población rural Wichí del oeste de la provincia de Formosa. Se tomaron medidas de peso y talla en 109 mujeres y 58 varones mayores de 12 años, estimándose el índice de masa corporal (IMC. Nuestros resultados muestran una alta prevalencia de sobrepeso y obesidad en esta población: 36% de las mujeres y 29% de los hombres tenían sobrepeso, mientras que 5% de las mujeres y 7% de los hombres eran obesos. También se encontró una asociación significativa entre el IMC y la edad. La ausencia de diferencias significativas en el IMC entre sexos resulta notable ya que son las mujeres las que constitucionalmente tienden a tener mayores valores de IMC. Se hipotetiza que, debido a la intervención de factores bioculturales, los hombres tienen un mayor acceso a alimentos que las mujeres. Estos resultados y otros obtenidos por nuestro equipo en comunidades Toba, contribuyen a un mejor entendimiento de los factores de riesgo sanitario en estas poblaciones y facilitan la aplicación de políticas de salud pública culturalmente más sensibles y, por lo tanto, más efectivas.

    Full Text Available Resumo O crack é um problema relevante de saúde pública no Brasil, em função dos danos e riscos individuais e sociais secundários ao seu uso/abuso. O objetivo deste artigo é descrever características das cenas de uso de crack na Capital e no Meio-Oeste de Santa Catarina. O projeto se valeu da metodologia Time-Location Sampling. Em janeiro-junho de 2011, foram mapeadas 41 cenas de uso de crack na Capital e 33 no Meio-Oeste catarinense. Após seleção aleatória das cenas a serem observadas, foram sorteados os dias e os turnos em que estas seriam observadas em detalhe, totalizando 98 cenas/turno na Capital e 62 no Meio-O-este. As observações foram registradas em caderno de campo, analisadas via análise de conteúdo de Bardin e discutidas à luz da literatura nacional e internacional. Os usuários de crack entrevistados eram majoritariamente adultos do sexo masculino, com uma maior associação entre estar em situação de rua e consumir a droga na Capital. Enquanto no Meio-Oeste a maioria das cenas estavam ativas no período noturno, na Capital, apresentaram-se ativas em todos os períodos. Foram identificadas práticas de risco associadas ao uso do crack, como associação de múltiplas drogas, prostituição, compartilhamento de cachimbo e favores sexuais em troca da substância.

    Full Text Available Estudo documental de abordagem histórico social, cujo objeto foi a trajetória de crescimento dos cursos superiores de enfermagem na região Centro-Oeste do Brasil. Os objetivos foram: levantar o número de cursos superiores de enfermagem criados na região Centro-Oeste, na série histórica 1933-2006; comparar o número de cursos vinculados a instituições públicas aos vinculados a instituições privadas na região em estudo; e comentar os nexos entre o contexto histórico e a configuração desses cursos no que se refere à vinculação institucional, ao longo dos anos. Até o final do ano de 1999, haviam sido criados na região Centro-Oeste 14 cursos de enfermagem, dos quais 57% eram privados e 43% públicos. Em decorrência das políticas de educação adotadas no país, principalmente na década de 90, observa-se a criação de mais 30 cursos na região entre os anos 2000 e 2006, perfazendo um total de 44 cursos superiores de enfermagem, dos quais 79,5% são privados e 20,5% públicos, sendo Goiás, o estado com maior concentração destes cursos. A rede privada expandiu-se na região e concentra, atualmente, a grande maioria dos cursos de enfermagem, o que nos faz entender que a mesma determina, quase que por completo, o perfil do futuro profissional de enfermagem.

    Full Text Available A região oeste da Bahia passa por acelerado processo de desenvolvimento agrícola, o que tem gerado problemas de infraestrutura nos municípios. A falta de saneamento básico e de coleta dos resíduos são alguns desses problemas, os quais têm papel importante no aumento de criadouros disponíveis aos culicídeos. Assim, considerando as possibilidades de contato entre vetor e população humana, o objetivo deste trabalho foi estudar a fauna de culicíeos adultos em uma área urbana no oeste da Bahia e verificar a presença de espécies de interesse em saúde pública. As amostragens de mosquitos adultos foram realizadas no município de Barreiras, de fevereiro de 2009 a janeiro de 2010, das 17h30min às 21h00min. Ao total foram capturados 1.744 mosquitos e oito gêneros foram identificados: Aedes, Coquilletidia, Culex, Limatus, Mansonia, Ochlerotatus, Psorophora e Uranotaenia. Culex quinquefasciatus foi a espécie mais frequente e abundante. Outras espécies encontradas, e que apresentam importância epidemiológica, foram Aedes aegypti e Ochlerotatus scapularis. Considerando que muitas espécies coletadas em Barreiras possuem importância epidemiológica e ocorrem mesmo durante a estação seca devido à ausência de saneamento básico, é importante que os municípios da região oeste da Bahia sejam alvo constante das atividades de vigilância epidemiológica.

    Full Text Available O principal objetivo deste artigo é analisar as implicações das transformações tecnológicas da agricultura paranaense e os impactos ambientais decorrentes dessas mudanças estruturais, elegendo como cenário a região Oeste do Paraná. O modelo agrário tecnológico introduzido na agricultura brasileira desde a década de 1950, e, posteriormente (década de 1970, especificamente no quadro agrícola paranaense, tem como uma de suas características centrais a exclusão dos pequenos produtores, estimulando a produção de cultivos de elevada cotação comercial (commodities, os quais por sua natureza requerem extensas áreas de plantio, em detrimento dos alimentos produzidos pela maioria dos produtores. Cabe destacar que a pressão do setor industrial sobre o setor agrícola, fortalecido após o processo de industrialização e de internacionalização do capital, é significativa. A metodologia empregada envolveu a revisão bibliográfica, relacionando os ciclos econômicos que marcaram a ocupação do território paranaense e a exploração dos recursos naturais, como também a manutenção das áreas de preservação ambiental, mais especificamente o Parque Nacional do Iguaçu, instituído em 1939, como reserva de Proteção Integral. A análise dos resultados permitiu considerar o caráter de dispersão das mudanças tecnológicas na agricultura do Estado do Paraná, entendendo que nem todas as regiões do Estado se tecnificaram e mecanizaram ao mesmo tempo.

    Full Text Available Os imigrantes italianos que chegaram a partir das últimas décadas do século XIX no RS estabeleceram-se na encosta superior do planalto, precisamente entre os vales dos Rios Caí e das Antas, e dedicaram-se às atividades agropecuárias. Após esta ocupação avançaram sobre novas terras e a partir do final da década de 1880, atingiram áreas que posteriormente passaram a denominar-se Vale do Taquari. O objetivo do estudo consiste em analisar as atividades agrícolas dos imigrantes italianos e seus descendentes na Microrregião Oeste do Vale do Taquari e as relações com o ambiente. A metodologia da pesquisa é qualitativa e os procedimentos metodológicos consistem na pesquisa bibliográfica e documental, pesquisa de campo com elaboração de diários e entrevistas com descendentes de italianos. Constatou-se que as práticas envolvendo atividades agrícolas, tais como cultivo do milho, trigo, uva, feijão e a criação de animais como gado, porcos e galinhas em áreas da Microrregião Oestes pelos imigrantes italianos e seus descendentes acarretaram significativos impactos ambientais.

    Full Text Available This article analyzes the development model of the Atlantic coast of Uruguay and its capacity to preserve relevant ecosystem services. The chosen study area was Playa Solari – Barra, one of the most important touristic spots of Uruguay (located in Laguna de Rocha, Rocha, Uruguay. This coastal zone has experienced important territorial changes during the last decades, with conflicts arising among traditional urban development for beaches, the recent strategies of rural-coastal tourism and natural and cultural heritage conservation strategies. The results show that the strong process of urban consolidation is negatively affecting the most important economic resources and ecosystem services in the study area, particularly those that directly promote touristic activities. For the last five years, the trend of urban development seems to point out towards an increase of the observed negative effects. Based on that evidence, this paper proposes specific strategies, particularly a new land use model, to revert negative impacts.

    Full Text Available The lead-zinc mineralizations from Western Cantabria are studied in this paper, mainly from a petrological and geochemical point of view. The host rocks are mesozoic dolomites which present some outstanding evidences: cavernous aspect, irregular distribution, coarsegrained, relict texture with ghosts and cloudy centers, and low geochemical content in Sr (50 ppm and high in Mn and Fe (1200 ppm and 4%. respectively, These characteristics aIlow classify them as originated by late diagenetic dolomitization processes.
    The primary ores are sphalerite, galena, pyrite, marcasite , and sometimes barite. These minerals fill cavities and other open spaces, being the most important texture composed by altemating bands of sphalerite of different colour ("colloform texture" with scattered crystals of galena, pyrite, and marcasite, The general morphology is tipically stratabound and not stratiform. The secondary minerals, product of weathering, inelude smithsonite from sphalerite, cerussite from galena, and goethite from pyrite and marcasite.
    The characteristics of the host rocks and mineralizations show they were formed epigenetically, with existence of a source rock, migration of mineralizating solutions and deposition of them in a host rock of dolomitic character.

    En este trabajo se hace un estudio de las mineralizaciones Pb-Zn del tipo Reocín en Cantabria, principalmente desde un punto de vista petrológico y geoquímico. Las rocas encajantes de las mineralizaciones son dolomías mesozoicas que poseen algunas características remarcables: aspecto cavernoso, estratificación difusa, distribución irregular, cristales de gran tamaño, 'textura relicta con existencia de fantasmas y "cloudy centers" y un bajo con tenido en estroncio (50 ppm. y alto en hierro y manganeso (4% y 1.200 ppm ., respectivamente. Estas características permiten clasificarlas como originadas por procesos de dolomitización diagenéticos tardíos.
    Las mineralizaciones primarias están constituidas por esfalerita, galena, pirita y marcasita y, en ocasiones, baritina. Estos minerales rellenan cavidades y otros espacios abiertos, siendo la textura más importante la compuesta por bandas alternantes de esfalerita de diferente tonalidad (''textura colomorfa" con cristales dispersos de galena, pirita y marcasita. La morfología general es típicamente "stratabound" y no estratiforme. Los minerales secundarios. producto de la alteración, incluyen smithsonita a partir de la esfalerita , cerusita de la galena y goethita de la pirita y marcasita.
    Las características de las rocas encajantes y de las mineralizaciones muestran que éstas se formaron epigenéticamente, con existencia de una roca madre, migración de soluciones mineralizantes y deposición de éstas en una roca caja de carácter dolomítico.

    The Anchisauripus isp. and Theropoda indet. dinosaurs tracks from the Triassic Los Rastros and Ischigualasto formations, at the Ischigualasto-Villa Union Basin, Western Argentina, are described in this paper. This record completes the paleontological data provided by rest of bones and increases the stratigraphic range of some taxa in which bones are either missing or scarse. On the other hand, this report also allows us to enlarge the faunistic assemblage of some vertebrate assemblages. [Spanish] Se describen huellas de dinosaurios teropodos asignados a Anchisauripus isp. y Theropoda indet. para las formaciones triasicas de Los Rastros e Ischigualasto en el Oeste de Argentina. Los sitios con huellas en la cuenca triasica de Ischigualasto - Villa Union complementan los datos paleontologicos ofrecidos por los restos oseos, ampliando el rango estratigrafico de algunos taxa donde sus huesos estan ausentes o son relativamente escasos e incluso permiten ampliar el cortejo faunistico de algunas asociaciones de vertebrados.

    Synopsis Genes linked to ALS susceptibility are being identified at an increasing rate owing to advances in molecular genetic technology. Genetic mechanisms in ALS pathogenesis appear to exert major effects in ~10% of patients, but genetic factors at some level may be important components of disease risk in most ALS patients. Identification of gene variants associated with ALS has informed concepts of the pathogenesis of ALS, aided the identification of therapeutic targets, facilitated research to develop new ALS biomarkers, and supported the establishment of clinical diagnostic tests for ALS-linked genes. Translation of this knowledge to ALS therapy development is ongoing. PMID:26515623

    Full Text Available O artigo examina a falência da Associação dos Produtores Alternativos (APA de Ouro Preto do Oeste, em Rondônia, buscando identificar elementos estruturantes e explicativos das relações entre atores locais e evidenciando seus próprios quadros interpretativos. A partir de um breve histórico da implantação do Projeto Integrado de Colonização (PIC Ouro Preto do Oeste, são destacadas a origem social dos colonos, sua cultura política e o tipo de capital social construído nos assentamentos. Por outro lado, apresenta-se a lógica das instituições envolvidas no desenvolvimento desse projeto. As relações entre os diversos atores institucionais são apresentadas como uma rede multiconectada, unindo os níveis local, regional, nacional e internacional. A análise mostra o descompasso entre a visão econômica das instituições de apoio, voltadas para a produção, e as aspirações dos produtores da APA. Ao final, concluímos que a falência pode estar associada a dois fatores interligados: a 'desconfiança' dos produtores da APA em relação aos órgãos de apoio à agricultura familiar (Comissão Executiva do Plano da Lavoura Cacaueira, Agência de Defesa Sanitária Agrosilvopastoril do Estado de Rondônia, Empresa de Assistência Técnica e Extensão Rural e a ausência dos governos estadual e municipal no grupo de atores do sistema de redes multiconectadas, no qual poderiam ter desempenhado um papel de mediadores entre aquelas diferentes aspirações. Finalmente, a questão colocada relativiza a noção de 'fracasso' associada à falência.

    Full Text Available O presente artigo apresenta os resultados de uma dissertação de mestrado em educação, realizada entre janeiro de 2004 a dezembro de 2006, sobre o processo de organização político-sindical dos profissionais da educação em Santa Catarina, mais particularmente no Oeste de Santa Catarina. O propósito fundamental desta pesquisa foi descrever a trajetória das lutas empreendidas pela categoria no período entre 1988 e 2006. Tomando como referência os mais importantes trabalhos sobre organização sindical no Brasil, desenvolvidos por Ricardo Antunes, Armando Boito, Leôncio Martins Rodrigues e outros, este trabalho descreve os processos de organização político-sindical dos docentes no Oeste de Santa Catarina. Por meio da pesquisa documental e das técnicas de memória oral, procurou-se conhecer as experiências vivenciadas pelos dirigentes sindicais envolvidos nesse processo. A investigação demonstrou que a organização política dos professores em Santa Catarina chegou ao seu ápice com a criação do Sindicato dos Trabalhadores em Educação (Sinte, em 1998, finalizando a forte tradição assistencialista alimentada pela Associação Catarinense dos Professores (ACP e a Associação dos Licenciados de Santa Catarina (Alisc, fundadas, respectivamente, em 1952 e 1966. O Sinte fortaleceu politicamente a categoria e foi decisivo para a conquista de inúmeros direitos trabalhistas para a categoria docente em Santa Catarina. A pesquisa mostra, também, que a partir da segunda metade dos anos 90 o movimento político-sindical dos professores começa a enfrentar dificuldades de mobilização e inicia um processo gradativo de enfraquecimento e deslegitimação, inclusive entre os professores e a comunidade escolar. O sindicalismo de luta foi substituído pelo de negociação.

    In the Nova Lacerda and Conquista D'Oeste regions, Mato Grosso State, SW part of the Amazonian Craton, mafic dikes trending NNW intrude the Nova Lacerda Granite (1462{+-}12 Ma), within the Jauru Domain, in the Rondonia-San Ignacio Province (1.55 - 1.3 Ga). The mafic swarm comprises diabases, metadiabases and amphibolites. Metadiabases originated from uralitization of diabases. These rocks have tholeiitic affinity and predominant basaltic composition. Some samples are andesi-basalts. The ages of diabases and metabasites are 1380 {+-} 32 Ma and 1330 {+-} 120 Ma respectively. Geochemical data indicate that the compositional variation of diabases and metadiadases is due to fractional crystallization of evolved tholeiitic magmas. The origin of the basaltic magmas is related to a heterogeneous mantle source. (author)

    Full Text Available Research on food planning has been recently proposed in North American and European planning to account for how cities might change their food provision to respond to the rising demands for a more sustainable and ethical food system. The purpose of this paper was to evaluate the agro-ecological potential of the Lisbon city region, Ribatejo e Oeste, to increase its Regional Food Self-Reliance (RFSR, through adopting demand restraint and food system relocalization approaches to food system sustainability. Three new diet scenarios were considered: meat-based, plant-based and strict vegetarian, defined in accordance with healthy dietary patterns. We used agro-climatic and agro-edaphic agricultural suitability models to evaluate the agro-ecological potential for RFSR, and proposed the use of Foodshed Landscape Plans within a landscape planning methodology. Results showed the extent of local food production that could improve food self-reliance, with 72%, 76%, 84% of total food needs in the meat-based, plant-based, and strict vegetarian scenarios, respectively. Thus, food system transformation by means of relocalization, is therefore ecologically feasible and would ensure the sustainable use of the ecological basis of food security. Additionally, a dietary transition would imply significant land sparing, which strengthens the demand restraint perspective for a transition to food system sustainability.

The research was conducted in 38 big and medium companies during 2005, using an exploratory and descriptive study. Companies are located in West and Northwest Paraná, a Brazilian State. The findings were analyzed using descriptive statistics. The results show the companies doesn't use new cost management practices or improved ones. The main reasons are: they don’t know these practices, the cost/benefit relationship isn’t favorable and the preference for conventional cost management practices.RESUMENEsta investigación tiene por finalidad identificar las prácticas de gestión de costos adoptadas por las empresas, en el contexto de su aceptación como necesarias al actual ambiente de mercado. El estudio se circunscribe a las transformaciones ocurridas en el ambiente de negocios en las últimas décadas, así como a las nuevas y/o perfeccionadas prácticas de gestión de costos. Entre estas prácticas se destaca el costeo y la gestión basada en actividades, el costo de la calidad, el costo meta, el costeo del ciclo de vida y el análisis de la cadena de valor, defendidas por algunos autores como las más adecuadas al nuevo ambiente. Se examinan los conceptos y justificativas comprendidos en estas prácticas de gestión de costo, desde un prisma crítico, confrontando las opiniones de diversos investigadores. Clasificado como de naturaleza descriptiva y exploratoria, el estudio se fundamenta en una investigación efectuada en 38 empresas de mediano y gran porte, situadas en las regiones Oeste y Noroeste del Estado de Paraná, cuyos datos se recolectaron por medio de entrevistas realizadas en el período de septiembre a diciembre de 2005. Para el análisis se utilizó la estadística descriptiva. Como conclusión se tiene que, las nuevas y/o perfeccionadas prácticas de gestión de costos no recibieron la debida atención por parte de las empresas

    Full Text Available La planificación de los recursos es un problema trascendental en los países en desarrollo y también en Cuba, por lo que hacer el mejor uso de los presupuestos limitados y de las escasas divisas, es de vital importancia. Planificar las cantidades de medicamentos necesarias, para lograr garantizar una disponibilidad adecuada de estos en todos los niveles de asistencia, es una tarea en la cual intervienen un sinnúmero de factores. El objetivo de este trabajo fue demostrar en qué medida la introducción del enalapril tabletas influyó en el consumo del captopril tabletas, mediante el análisis de los patrones de consumo de los medicamentos inhibidores de la enzima convertidora de angiotensina en el territorio oeste de La Habana entre marzo de 2005 y diciembre de 2009. Para ello se realizó un estudio de utilización de medicamentos de consumo, de tipo descriptivo, observacional y retrospectivo. Se calcularon las DHD (dosis por mil habitantes día. Los resultados de este trabajo demuestran cómo en este grupo hay un desplazamiento del consumo hacia el enalapril. Este es un comportamiento lógico por la comodidad de la administración y la menor incidencia de efectos adversos. Sin embargo, el captopril se mantiene en valores entre 20 y 30 DHD x 1 000 habitantes ya que hay un grupo de pacientes que continúan con este tratamiento y es de elección en la crisis hipertensiva.

    Full Text Available Los Cuartos Granite crops out on the western flank of the Cumbres Calchaquíes, east of Tafí del Valle, Tucumán Province, Argentina. It has a granitic to granodioritic composition, of two micas, being biotite dominant. The granite is medium grained and inequigranular, with rare K-feldspar megacrysts. It contains host-rock xenoliths with different degrees of assimilation. The granite intrusion produced con tact metamorphism in the surrounding basement, with development of andalucite porphyroblasts and poikiloblastic biotite. The granite is calk-alkaline and peraluminous, and is K- and P-rich and Ca- and Na poor compared to other granitoids of the region. The pluton shows late-tectonic features with regard to the regional deformation. The granite possibly intruded during the Ordovician (Famatinian Cycle and its emplacement was structurally controlled by the Tafí Megafracture. Los Cuartos Granite and other intrusive bodies of the region share similar petrographical, geochemical, structural and geochronological characteristics.

    Full Text Available A precipitação pluviométrica, dentre os elementos hidrológicos, é o que mais interfere na vida humana, uma vez que, se configura como a principal entrada de água no sistema hidrológico. Atualmente uma das soluções para realizar a caracterização e estimativa das precipitações intensas é a utilização de curvas Intensidade-Duração-Frequência (IDF, as quais consistem em modelos matemáticos semi-empíricos que preveem a intensidade precipitada por meio da duração e distribuição temporal. Neste contexto, esse estudo objetiva estimar a função IDF para os municípios de Jaru e Machadinho d’Oeste, localizados no estado de Rondônia – Brasil, por meio da metodologia da desagregação de chuvas diárias, que gera séries sintéticas com duração em intervalos menores, por meio de coeficientes que transformam chuva de 24h em outras de menor duração, permitindo assim o desenvolvimento de curvas IDF. As equações geradas apresentaram um coeficiente de ajuste de aproximadamente 96% para o município de Jaru e 92,85% para Machadinho d’Oeste. Por fim, constatou-se que as equações propostas para a estimativa da intensidade das precipitações máximas são de grande aplicabilidade tanto para o município de Machadinho d’Oeste quanto para Jaru.

    Full Text Available As redes agroindustriais, com apoio deliberado do Estado, vêm se estabelecendo nos lugares e produzindo uma reestruturação produtiva condizente com seus interesses, atingindo tanto a base técnica quanto a econômica e social do setor agrícola, e promovendo a formação e/ou a reestruturação de regiões que passam a encarnar especializações territoriais. O Oeste Baiano se configura como um desses exemplos de região funcional ao agronegócio, contendo, principalmente a partir da década de 1980, condições favoráveis à expansão dessa atividade, com investimento maciço de capital público e privado na tecnificação do território. Essa região tem sua organização socioespacial atual pautada por redes agroindustriais que participam dos circuitos espaciais de produção e círculos de cooperação da produção moderna de grãos, principalmente da soja. Os conteúdos urbanos e os papéis regionais das principais cidades do Oeste Baiano resultam de uma crescente integração entre o agronegócio e os circuitos da economia urbana, transformando tais cidades em espaços funcionais às exigências produtivas do campo moderno. Nessa região, a difusão do agronegócio tem-se processado de forma conservadora e excludente, traduzindo-se no reforço de históricas desigualdades socioespaciais, bem como na criação de novas.

    Full Text Available Abstract Definition of the disease AL amyloidosis results from extra-cellular deposition of fibril-forming monoclonal immunoglobulin (Ig light chains (LC (most commonly of lambda isotype usually secreted by a small plasma cell clone. Most patients have evidence of isolated monoclonal gammopathy or smoldering myeloma, and the occurrence of AL amyloidosis in patients with symptomatic multiple myeloma or other B-cell lymphoproliferative disorders is unusual. The key event in the development of AL amyloidosis is the change in the secondary or tertiary structure of an abnormal monoclonal LC, which results in instable conformation. This conformational change is responsible for abnormal folding of the LC, rich in β leaves, which assemble into monomers that stack together to form amyloid fibrils. Epidemiology AL amyloidosis is the most common type of systemic amyloidois in developed countries with an estimated incidence of 9 cases/million inhabitant/year. The average age of diagnosed patients is 65 years and less than 10% of patients are under 50. Clinical description The clinical presentation is protean, because of the wide number of tissues or organs that may be affected. The most common presenting symptoms are asthenia and dyspnoea, which are poorly specific and may account for delayed diagnosis. Renal manifestations are the most frequent, affecting two thirds of patients at presentation. They are characterized by heavy proteinuria, with nephrotic syndrome and impaired renal function in half of the patients. Heart involvement, which is present at diagnosis in more than 50% of patients, leading to restrictive cardiopathy, is the most serious complication and engages prognosis. Diagnostic methods The diagnosis relies on pathological examination of an involved site showing Congo red-positive amyloid deposits, with typical apple-green birefringence under polarized light, that stain positive with an anti-LC antibody by immunohistochemistry and

    Full Text Available A produção agrícola apresenta características particulares, se comparada a outras atividades econômicas, sendo uma das mais marcantes a extensão dos riscos aos quais está exposta. O cultivo de arroz (Oryza sativa L. irrigado, embora pareça menos suscetível do que as culturas de sequeiro, também está exposto a riscos. Maior produtor mundial de arroz fora da Ásia, o Brasil tem no Rio Grande do Sul seu principal estado produtor. O objetivo deste trabalho foi analisar como o orizicultor da Fronteira Oeste do Rio Grande do Sul percebe os riscos da sua atividade e quais medidas adota para geri-los. A metodologia empregada envolveu aplicação presencial de questionários a orizicultores, de acordo com uma amostra não probabilística. Os resultados indicaram que os orizicultores atribuem maior relevância aos riscos socioeconômicos do que aos de produção. Evidencia-se, assim, a importância da gestão do negócio pelos orizicultores, para que sua atividade esteja integrada com os demais elos da cadeia produtiva. A redução de custos pode ser uma alternativa para mitigação de riscos de mercado, apontados como os mais relevantes pelos orizicultores. A percepção dos orizicultores sobre riscos e sobre medidas para mitigá-los pode representar a base na formulação de estratégias de gestão de riscos.Agricultural production has many different influencing factors compared to other economic activities.

    Full Text Available Since the late 1970s, canine parvovirus type 2 (CPV-2 has emerged as a causative agent of fatal severe acute hemorrhagic enteritis in dogs. To date, three antigenic types of CPV-2 were described worldwide (CPV-2a/b/c. This study was conducted to determine the variants of CPV-2 circulating in dogs from the Cuiabá Municipality in Midwestern Brazil. Out of 50 fecal samples, collected between 2009 and 2011, 27 tested positive for CPV-2. A 583 bp fragment of the VP2 gene was amplified by PCR, 13 representative samples were analyzed further by DNA sequencing. All strains were characterized as CPV-2c, displayed a low genetic variability although observed several amino acid substitution. These findings indicated that CPV-2c has been circulating in dogs from the Cuiabá Municipality in Midwestern Brazil.Desde o final dos anos de 1970, o parvovírus canino tipo 2 (CPV-2 tem emergido como agente de severa e fatal enterite hemorrágica, principalmente em cães com idade inferior a seis meses. Três variantes antigênicas de CPV-2 foram descritas mundialmente (CPV-2a/b/c. O objetivo do estudo foi determinar a presença do CPV-2 e suas variantes circulantes em cães no Município de Cuiabá, Centro-oeste, Brasil. Das 50 amostras fecais, coletadas entre 2009 e 2011, 27 foram positivas para CPV-2 na PCR, sendo 13 analisadas pelo sequenciamento de um fragmento de 583 pares de base do gene VP2. Todas as cepas foram caracterizadas como CPV-2c e apresentaram baixa variabilidade genética. Estes achados indicaram que o CPV-2c está circulando na população canina do Município de Cuiabá, Região Centro-Oeste do Brasil.

    Determinou-se a soma térmica, expressa em graus-dia, para o subperíodo semeadura-maturação do feijoeiro comum, cultivar Carioca. O estudo foi desenvolvido com base em dados fenológicos de experimentos de campo, realizados no período de entressafra, com o uso de irrigação, no ano de 2006, e no período de safra normal, com e sem o uso de irrigação, no ano de 2007. Os experimentos foram conduzidos no Instituto Federal de Rondônia (IFRO, no município de Colorado do Oeste, Estado de Rondônia. A soma dos graus-dia (GD foi determinada utilizando-se dois métodos: o primeiro considerando-se três diferentes temperaturas-base inferiores (Tb, 10°C, 12°C e 15°C, e o segundo tomando-se as temperaturas-base inferiores 10°C, 12°C e 15°C e a temperatura-base superior (TB de 35°C. Os valores diários da temperatura do ar foram obtidos na estação meteorológica do IFRO, instalada próxima aos locais dos experimentos. Os métodos não apresentaram diferença significativa entre si, fornecendo valores médios que variaram de 686 a 1.261,9 graus-dia, com Tb de 15°C, para o período de safra normal com irrigação, e de 10°C, para o período de entressafra, respectivamente. Pelos resultados obtidos, evidencia-se que as condições de soma térmica, para o cultivo do feijão, são favoráveis, principalmente no período de safra normal com irrigação.

    Full Text Available Este artigo analisa as estratégias de reprodução social de estabelecimentos familiares com o objetivo de avaliar suas formas de inserção nos mercados e possíveis implicações socioambientais. O estudo de caso contou com 37 entrevistas com produtores convencionais e orgânicos no Extremo Oeste Catarinense. Enquanto as criações integradas demandam especialização, a agroecologia orienta-se pela diversificação produtiva. Entre esses polos, a atividade leiteira apresenta elevada expressão social, mas com reconfigurações importantes em curso na sua relação com os mercados. A demanda por maior escala, necessária para manter-se nessa cadeia e obter melhores preços, expande o modelo produtivista de elevado uso de insumos, o qual subjuga a preservação ambiental e reduz a margem de manobra frente às oscilações de mercado e aos possíveis problemas sanitários. Nesse contexto, o Estado e as organizações representativas do setor podem: a assumir papel ativo, disputando a construção dos mercados; ou b aceitar o fatalismo da concentração excludente em curso.

Utilizou-se o método histórico-analítico, considerando aspectos da interpretação antropológica de outros autores e a própria vivência do autor. O artigo procura mostrar a necessidade da pesquisa de campo regional em face da generalização estatística que omite aspectos importantes. Dessa maneira, mostra como a produção de milho se desenvolveu principalmente em Goiás, considerando os aspectos culturais decorrentes da origem da população. Ao mesmo tempo procura realçar a produção do arroz de sequeiro como “amansadora” das terras de Mato Grosso, no processo de abertura da fronteira do cerrado.

    Full Text Available Com o uso intensivo de herbicidas inibidores da acetolactato sintase (ALS em áreas cultivadas com soja, no município de São Gabriel d'Oeste (MS, Brasil, selecionou-se um biótipo resistente da planta daninha Bidens pilosa. A confirmação bioquímica desta resistência, no entanto, é muito difícil de ser feita em campo. Assim, realizou-se um bioensaio com o objetivo de testar a sensibilidade da ALS desse biótipo aos herbicidas inibidores dessa enzima, por meio da aplicação simultânea de herbicidas inibidores da ALS e da KARI (cetoácido reductoisomerase. Para a inibição desta última enzima, utilizou-se o teste CPCA (ácido 1,1-ciclopropanodicarboxílico. Por ele, confirmou-se que a resistência do biótipo de Bidens pilosa é decorrente da insensibilidade da ALS aos herbicidas, que visam inibi-la; pois, quanto maior a quantidade de acetoína, maior é a atividade da enzima e mais intensa a coloração desenvolvida, proporcionando maiores valores nas leituras de absorbância.

    Full Text Available O Centro-Oeste do Brasil se destaca como um pólo produtor de soja. Pela crise fiscal do Estado, a partir dos anos 80, a malha rodoviária brasileira perde investimentos públicos para sua ampliação, conservação e restauração, refletindo na competitividade internacional da oleaginosa dos cerrados. Isso porque o principal modal utilizado para o escoamento da produção do grão aos portos das regiões Sul e Sudeste é o rodoviário, com destaque para as rodovias BR 163 e 364. Por conta da inadequação desse modal às características do produto e às longas distâncias percorridas, aliada ao estado precário de conservação da malha rodoviária do País, 25% da receita de vendas da produção de soja está comprometida com os custos internos de transportes. Neste trabalho, apontam-se perspectivas e possíveis soluções à reversão desse cenário, via concessões rodoviárias e Parcerias Público-Privadas (PPP. Analisa-se o uso de diferentes modais para o escoamento da soja do Centro-Oeste, e conclui-se que os hidroviários e ferroviários são os mais eficientes, em razão da eficiência energética e da maior produtividade à movimentação de cargas de densidade mais elevadas por distâncias maiores - o que conferiria custos menores de circulação.The Center-Western of Brazil is known to be a soy production center.

    Full Text Available Tomando como foco o município de São Carlos, um dos principais centros da economia cafeeira do oeste paulista durante a virada do século XIX para o XX, o artigo analisa as tensões presentes nas relações interpessoais tecidas entre negros, de um lado, e fazendeiros e pequenos proprietários rurais, de outro. Por meio da leitura de dois inquéritos policiais da época, percebeu-se que essas relações eram mediadas por determinados códigos morais, os quais, por sua vez, delimitavam certas normas de sociabilidade. Quando alguns destes códigos eram quebrados, as situações de conflito se potencializavam. Pode-se afirmar que, se a proximidade com pessoas de posse ainda era, para a população negra do pós-abolição, uma das principais fontes para obtenção de recursos materiais e simbólicos, as relações de poder inscritas nesses vínculos não deixavam de produzir contestações quanto às identificações e hierarquias encerradas no âmbito familiar. De modo geral, acredita-se que as disputas de poder presentes nessas interações podem estar relacionadas à renegociação, trazida pelo fim do escravismo, de determinadas formas de distinção social.

    Full Text Available A influência de uma localidade sobre seus vizinhos é sempre vista como uma interdependência entre as regiões em estudo e a localização afeta a resposta da produção agrícola às alterações de preços ou de políticas. O objetivo geral é determinar a importância dos efeitos e inter-relações decorrentes da localização na resposta da produção agrícola aos preços, na região Centro-Oeste, no período entre 1975 e 1995. Contribui-se para a literatura econômica ao conciliar um modelo de função de lucro translog com efeitos de dependência espacial nos resíduos do sistema estimado de parcelas de lucros. Existem evidências econométricas da dependência espacial nos resíduos do modelo, confirmadas pelo teste de hipótese para os parâmetros espaciais. Ocorreram altas autocorrelações espaciais positivas nos produtos, com parâmetros espaciais sempre acima de 0,91. As áreas selecionadas em geral apresentaram oferta-preço elásticas para milho e oferta-preço inelásticas para arroz e feijão. Os efeitos espaciais alteram de forma decisiva as elasticidades calculadas, mostrando que todos os produtos analisados sofrem destes efeitos. Enfatiza-se que estudos com cortes seccionais e dados geograficamente dispostos devem ser avaliados quanto à presença de dependência espacial.

    Full Text Available A região Sudoeste do Rio Grande do Sul apresenta áreas de intensa degradação, com extensas porções da superfície recobertas por areias submetidos aos condicionantes climáticos locais, sendo denominadas de areais ou campos de areias. Nesse contexto, o objetivo desse trabalho foi realizar uma análise da evolução da arenização da Bacia Hidrográfica do Arroio Puitã no período 1984 a 2014, através de mapeamento multitemporal. Assim se seguiram algumas etapas: primeiramente se deu a coleta de dados; após, o trabalho de campo; a seguir se deu a etapa de geoprocessamento com a confecção dos mapas de uso e cobertura da terra dos anos de 1984, 1994, 2004 e 2014 de toda a Bacia, a validação das classificações e as análises geográficas. A partir do mapeamento da arenização na bacia foi encontrada uma expansão considerável da área para os períodos correspondentes de 1984-1994 e 1994-2004, e uma redução de área em um terceiro período de 2004-2014, no entanto considerando todo o período estudado foi verificado apenas um aumento de 1,87 km² de área. Assim se observou que o mapeamento da arenização no Oeste do RS, visando o monitoramento da mesma área considerando um grande intervalo temporal foi mais eficaz utilizando-se do mapeamento multitemporal.

    Wettability and interfacial interaction of the Ta2O5/Cu-Al system were studied. Pure Cu does not wet the Ta2O5 substrate, and improved spreading is achieved when relatively a high fraction of the active element (~40 at.% Al) was added. The Al2O3 and AlTaO4 phases were observed at the Ta2O5/Cu-Al interface. A thermodynamic evaluation allowed us to suggest that the lack of wetting bellow 40 at.% Al is due to the presence of a native oxide, which covers the drop. The conditions of the native oxide decomposition and the formation of the volatile Al2O suboxide strongly depend on the vacuum level during sessile drop experiments and the composition of the Cu-Al alloy. In our case, Al contents greater than 40% provides thermodynamic conditions for the formation of Al2O (as a result of Al reaction with Al2O3) and the drop spreading. It was suggested that the final contact angle in the Ta2O5/Cu-Al system (50°) is determined by Ta adsorption on the newly formed alumina interlayer.

    Full Text Available In order to identify and characterize the agent of a suggestive clinical case of Gumboro disease (GD that affected a 34-day-old broiler flock in Buriti Alegre (Goias State, Midwestern Brazil in the year 2001, we carried out a combination of classic and modern virological methods. Histopathological analysis of the bursa revealed necrosis, presence of depleted follicles, some infiltration of heterophils, edema and formation of cystic cavities that are compatible with lesions observed in GD. Inoculation of embryonated eggs of specific pathogen-free (SPF chickens with macerated bursa suspension resulted in embryo mortality and lesions which were also compatible with those caused by IBDV. A sample of bursa was submitted to a nested reverse transcriptase-polymerase chain reaction (RT-PCR procedure to amplify the hypervariable region of the VP2 gene. The amplicon that was obtained from this sample (BR-GO was digested with the restriction enzymes TaqI, StyI and SspI, but not with SacI, a pattern similar to that observed with very virulent IBDV (vvIBDV strains. Furthermore, nucleotide sequence analysis revealed alanine, isoleucine, and isoleucine at amino acid positions 222, 256, and 294, respectively, which are also found in vvIBDV strains. Finally, phylogenetic analysis grouped BR-GO isolate with other vvIBDV strains.Para identificar e caracterizar o agente causador de um quadro clínico sugestivo de doença de Gumboro (DG que afetou um plantel de frangos de corte com 34 dias de idade, em Buriti Alegre (estado de Goiás, centro-oeste do Brasil, no ano de 2001, procedeu-se uma combinação de métodos virológicos clássicos e modernos.

    Full Text Available Rentabilidade insatisfatória tem provocado diminuição paulatina do parque cafeeiro no Estado de São Paulo. Entre as alternativas para a solução deste problema, duas se destacam: a irrigação das lavouras e a certificação das propriedades. Mesmo em regiões consideradas aptas à cultura do café arábica (Coffea arabica L., o uso da irrigação pode promover, na média dos anos, aumento de produtividade de grãos. Além disso, a certificação do produto favorece sua diferenciação no mercado e pode melhorar os resultados econômicos da atividade. Este trabalho teve por objetivo avaliar o desenvolvimento e a produtividade de cafeeiros submetidos a sistemas irrigados ou não, comparando os dados econômicos na comercialização do café certificado ou não, nas condições da Região Centro-Oeste do Estado de São Paulo. O delineamento utilizado no campo foi o de blocos ao acaso, com dois tratamentos (com e sem irrigação por gotejamento e dez repetições. Foram calculados os custos de produção, bem como a lucratividade com a venda do produto final. A irrigação aumentou o desenvolvimento e a produtividade dos cafeeiros. Houve o retorno do investimento a partir da terceira safra. A venda de café certificado possibilitou resultados econômicos em média de 224,5% superiores ao não certificado. A irrigação aliada à venda de café certificado proporcionou saldo financeiro 1.192% superior ao café não irrigado e não certificado.An unsatisfactory profitability has led to the gradual decline of the coffee plantations in São Paulo.

    Full Text Available O objetivo deste estudo foi avaliar as preferências dos consumidores de café da região oeste do Paraná, em relação ao ponto de torra e à granulometria de moagem. Foram realizadas análises sensoriais de preferência e físico-químicas. As análises físico-químicas foram utilizadas para monitorar as mudanças ocorridas nos produtos ao longo do processo de torra. Os cafés com torras mais leves foram pouco aceitos. O café que apresentou aparência global, aroma e sabor preferido foi o que apresentava uma torra média escura, mais próxima das torras tradicionais brasileiras. A torra mais escura foi bem aceita apenas em relação à aparência. A moagem fina foi preferida em relação à aparência global do produto, mas, apesar de ter apresentado maior acidez, os provadores não diferenciaram seu sabor.This study aimed the evaluation of the consumers preference for coffee in the west region of Paraná State, Brazil, in relation to the roasting degree and grinding granulometry. Sensorial preference and physical-chemichal analysis were made. The physical-chemichal analysis were used to monitor the changes that occurred in the products along the roasting process. The samples of coffee with light toasts were little accepted. The kind of coffee that presented preferred global appearance, aroma and taste was the one which presented average dark toasting, which is the one that is more similar to the traditional Brazilians toastings. The darkest toasting, was well-accepted in relation to appearance. The thin milling was preferred in relation to the global appearance of the product, but in spite of having presented major acidity the tasters did not make difference about its taste.

    Full Text Available Meningitis and encephalitis are complications of West Nile virus (WNV infection. Although WNV is endemic in North America, the virus has recently been reported in Colombia and Argentina. Investigation of WNV in Brazil is important since this virus has never been studied previously in this country. OBJECTIVE: To investigate the presence of WNV infection in viral encephalitis/meningitis cases of unknown etiology in the city of Rio de Janeiro, Brazil. METHOD: Thirty-seven adults with viral meningitis/encephalitis had their serum and CSF tested for WNV antibodies using the ELISA method. RESULTS: Only one case was WNV-positive, but this case was also positive for dengue. The plaque reduction neutralization test distinguished infections, and was negative for WNV. CONCLUSION: WNV can be confused with dengue infection. Their symptoms and neurological picture are similar. We did not find WNV in any patients with encephalitis and meningitis in the city of Rio de Janeiro. Up to now, it has not been detected in BrazilMeningite e encefalite são complicações da infecção pelo vírus do Oeste do Nilo (VON. Embora o VON seja endêmico na América do Norte, recentemente o vírus foi descrito na Colômbia e Argentina. Sua pesquisa no Brasil é importante uma vez que o vírus nunca fora estudado antes em nosso país. OBJETIVO: Investigar a presença do VON em casos de meningite e encefalite viral de etiologia desconhecida, na cidade no Rio de Janeiro, Brasil. MéTODO: Trinta e sete adultos com quadro de meningite/encefalite tiveram seu LCR e soro testados para anticorpos anti-VON, pelo método ELISA. RESULTADOS: Apenas um caso obteve sorologia positiva para VON, mas a sorologia para dengue também fora positiva. O teste da neutralização por redução de placa foi utilizado para distinção entre as infecções, sendo negativo para VON. CONCLUSÃO: A infecção por VON pode ser confundida com a infecção pelo vírus da dengue, seus sintomas e quadro neurol

Neste trabalho, avaliou-se a incidência do raquitismo em 108 talhões (principalmente de primeiro e segundo cortes distribuídos em 7 municípios do Espírito Santo, sul da Bahia e oeste de Minas Gerais, nos anos de 2003 e 2004, totalizando 558 ha amostrados. Para detecção do patógeno empregou-se a técnica sorológica Dot Blot-EIA (Dot Blot Enzyme Imunoassay. O raquitismo foi diagnosticado em 67,6% dos talhões amostrados (67,7% da área. Em 2003, a incidência média de colmos infectados (IC% correlacionou-se positivamente com a idade de corte (4,8% nas áreas de primeiro corte e 10,3% nas áreas de sexto corte. No ano de 2004, observou-se elevada incidência de raquitismo em cana de primeiro corte (IC=18%. A doença foi diagnosticada em 28 dentre 34 variedades estudadas. Nestas, a incidência varietal média variou entre 0,6 e 42%, em áreas predominantemente de primeiro e segundo corte, atingindo IC máxima de 59,5% em talhão de cana-planta da variedade RB855113. As variedades RB72454, SP711406 e SP813250, que tiveram número razoável de talhões amostrados, apresentaram geralmente valores de IC (por talhão menores que 10%. Conclui-se que o raquitismo-da-soqueira encontra-se amplamente disseminado nas regiões estudadas e que as mudas utilizadas para a renovação dos canaviais possuem altos índices de contaminação por Lxx. Estudos adicionais devem ser conduzidos para se caracterizar variedades regionais promissoras quanto à resistência/tolerância ao raquitismo, visando-se aperfeiçoar o manejo varietal e melhorar a sanidade das mudas.

    Full Text Available Das Interview ist nach wie vor das beliebteste sozialwissenschaftliche Verfahren des Datengewinns. Ökonomie der Erhebung, Vergleichbarkeit und die Möglichkeit, Einsicht in Praxisbereiche und historisch-biografische Dimensionen zu erhalten, die der direkten Beobachtung kaum zugänglich sind, machen seine Attraktivität aus. Zugleich mehren sich Kritiken, die seine Leistungsfähigkeit problematisieren, indem sie auf die begrenzte Reichweite der Explikationsfähigkeiten der Befragten, die Reaktivität der Erhebung oder die Differenz zwischen Handeln und dem Bericht über Handeln verweisen. Im Beitrag wird zwischen Ansätzen, die das Interview als Text, und solchen, die es als Interaktion verstehen, unterschieden. Nach dem Text-Verständnis werden Interviews unter inhaltlichen Gesichtspunkten analysiert und als Zugang zu einer vorgängigen sozialen oder psychischen Wirklichkeit angesehen. Das Interaktions-Verständnis versteht Interviews dagegen als situierte Praxis, in welcher im Hier und Jetzt von InterviewerInnen und Befragten gemeinsam soziale Sinnstrukturen hergestellt werden. Anhand ubiquitärer Phänomene der Interviewinteraktion – Fragen, Antworten und die Selbstpositionierung von InterviewerInnen und Befragten – werden Praktiken des interaktiv-performativen Handelns im Interview dargestellt. Ihre Relevanz für die Interviewkonstitution und ihre Erkenntnispotenziale für die Interviewauswertung werden aufgezeigt. Es wird dafür plädiert, die interaktive Konstitutionsweise von Interviews empirisch zu erforschen und methodisch konsequent zu berücksichtigen.

    Full Text Available INTRODUÇÃO: O laboratório do Pólo da Alta Sorocabana de Presidente Prudente, SP, em parceria com outras instituições de pesquisa, realizou estudos pertinentes aos morcegos da região oeste do Estado de São Paulo, Brasil. Para tal, foram pesquisadas algumas situações, tais como: a isolamento do vírus rábico, no período 2006 a 2008; b as respectivas variantes antigênicas; c abrigos diurnos do morcego hematófago Desmodus rotundus. MÉTODOS: As amostras para exame foram provenientes de morcegos não hematófagos encaminhadas ao laboratório sendo submetidas aos testes de imunofluorescência direta e prova biológica. As amostras positivas foram caracterizadas antigenicamente por meio do teste de anticorpos monoclonais. Quanto aos morcegos, foram identificados e classificados, e também foi realizado mapeamento de abrigos dos mesmos. RESULTADOS: O laboratório recebeu 1.113 morcegos não hematófagos para diagnóstico laboratorial, sendo 11 (1% deles positivos, e dentre as amostras positivas, 5 (45,5% delas tiveram variante antigênica 3 associada ao morcego D. rotundus e 4 (36,5% foram compatíveis com amostras de morcegos insetívoros. Foram pesquisados 16 abrigos de morcegos hematófagos e observou-se a presença de outras 3 espécies de morcegos não hematófagos convivendo com eles. CONCLUSÕES: Os experimentos mostraram que o vírus rábico continua circulando na região com pelo menos 3 variantes antigênicas, e que, a coabitação de morcegos hematófagos com não hematófagos pode ter alguma relação com a disseminação do vírus rábico.INTRODUCTION: The Polo da Alta Sorocabana Laboratory in Presidente Prudente, SP, in partnership with other research institutions, conducted studies related to bats from the western region of the State of Sao Paulo, Brazil.

    ão geralmente negligenciadas como um reservatório, e as perdas econômicas não são consideradas. Para avaliar a prevalência do parasitismo gastrintestinal e associações entre os gêneros e espécies de parasitos, com ênfase na fasciolose, caprinos crioulos da região andina e do planalto do oeste de Argentina foram avaliados por meio de técnicas coprológicas. Oitenta e cinco por cento dos animais hospedaram um ou mais tipos de parasitos, enquanto 46% hospedaram infecções mistas. Foram encontradas associações significativas entre F. hepatica + ovos de estrongilídeos, Eimeria sp. + Nematodirus sp. e Nematodirus sp. + Trichuris ovis. Mais estudos são necessários para definir a causalidade dessas associações e sua relevância na epidemiologia. Raramente F. hepatica é considerada como um parasito de cabra no país, mas uma prevalência de 33% suscita uma interrogação sobre o papel dos caprinos na transmissão e disseminação desse trematódeo zoonótico.

    Full Text Available In diesem Artikel werden unterschiedliche metaphorische Verwendungen des Pornografiebegriffs und deren Implikationen untersucht. Während die Existenz von Pornografie der feministischen Anti-Porno-Bewegung als Erklärung für die anhaltende Diskriminierung von Frauen in westlichen Gesellschaften dient, nutzen rechtskonservative Kräfte den Pornografievorwurf als Rechtfertigung für die Zensur von als deviant empfundenen Identitäten und sexuellen Praktiken.This article examines different metaphorical uses of the term pornography and the resulting implications. While the existence of pornography for the feminist anti-porno movement serves as factor in the continuing discrimination of women in western societies, conservative powers on the right use the allegation of pornography as a justification for censorship of those identities and sexual practices deemed deviant.

    Full Text Available The Subbetic sierras of Las Cabras to the Gibalto form an arched structure, giving it a high relief, constituted by many tectonic slices, verging to the South in its southern border and to the North and West in its concave border. Although it could be interpreted as an allochthonous structure, really is rooted in the transitional area between the Median and the Internal Subbetic. Several local factors have influenced this complex structure, but the final cause is the oblique collision (transpression of the In-ternal Zone against External Zone of the Betic Chain, producing an important strike-slip system.

    Las sierras subbéticas de las Cabras al Gibalto forman una estructura arqueada, que da un fuerte relieve, constituida por escamas tectónicas, vergentes al sur en su borde convexo, meridional, y al nor-te y oeste en su borde cóncavo. Aunque podría interpretarse como una estructura alóctona, se en-cuentra enraizada en el área de tránsito entre el Subbético Medio y el Interno. En su génesis han in-fluido varios factores locales pero la causa que controla a todos ellos es la colisión oblicua, en trans-presión, de la Zona Interna Bética contra la Externa, que produjo un importante sistema de desgarre.

    1993-06-15

    Everybody at Lawrence Berkeley Laboratory's Center for Beam Physics is pleased with the rapid progress in commissioning LBL's Advanced Light Source (ALS) electron storage ring, the foundation for this third-generation synchrotron radiation facility. Designed for a maximum current of 400 mA, the ALS storage ring reached 407 mA just 24 days after storing the first beam on 16 March. ALS construction as a US Department of Energy (DOE) national user facility to provide high-brightness vacuum ultra-violet and soft x-ray radiation began in October 1987. One technical requirement marking project completion was to accumulate a 50-mA current in the storage ring. The ALS passed this milestone on 24 March, a week ahead of the official deadline. Once injected, the electron beam decays quasi-exponentially primarily because of interactions with residual gas molecules in the storage-ring vacuum chamber. Eventually, when the pressure in the vacuum chamber with beam decreases toward the expected operating level of 1 nano Torr, it will only be necessary to refill the storage ring at intervals of four to eight hours. At present the vacuum is improving rapidly as surfaces are irradiated (scrubbed) by the synchrotron radiation itself. At 100 mA, beam lifetime was about one hour (9 April)

    The change in the microstructural parameters and microhardness values in 6.5 MeV proton irradiated pure Al and Al5083 alloy samples have been evaluated using different model based techniques of X-ray diffraction Line Profile Analysis (XRD) and microindendation techniques. The detailed line profile analysis of the XRD data showed that the domain size increases and saturates with irradiation dose both in the case of Al and Al5083 alloy. The corresponding microstrain values did not show any change with irradiation dose in the case of the pure Al but showed an increase at higher irradiation doses in the case of Al5083 alloy. The microindendation results showed that unirradiated Al5083 alloy has higher hardness value compared to that of unirradiated pure Al. The hardness increased marginally with irradiation dose in the case of Al5083, whereas for pure Al, there was no significant change with dose.

    Full Text Available OBJETIVO: Descrever a prevalência de infecção por HIV em gestantes e a taxa de transmissão vertical, segundo o perfil socioeconômico dos bairros de residência das mães. MÉTODOS: Estudo ecológico exploratório utilizando a base de dados do Sistema de Informação de Agravos de Notificação de gestantes HIV-positivas e aids em crianças notificadas entre 2000 e 2006 em Vitória, ES. Para análise das informações socioeconômicas foi utilizado o Índice de Qualidade Urbana. A prevalência de HIV em gestantes e a taxa de transmissão vertical foram calculadas. A distribuição espacial dos casos foi realizada no programa Terraview 3.2.0. Para verificar a associação entre a qualidade urbana e a prevalência de HIV em gestantes utilizou-se o modelo de regressão de Poisson. RESULTADOS: Um total de 137 gestantes e 14 crianças infectadas por transmissão vertical foi notificado no período. Sete crianças correspondiam a mães HIV-positivas sem notificação de caso no período analisado. A prevalência de infecção em gestantes no período foi de 0,44% e a taxa de transmissão vertical foi de 9,7%. CONCLUSÕES: A prevalência de infecção por HIV em gestantes e a transmissão vertical associam-se à qualidade urbana do bairro de residência, indicando que os bairros com menor qualidade urbana devem ser priorizados quanto às ações para redução da transmissão vertical.OBJETIVO: Analizar factores asociados a la ocurrencia de recidiva en hanseníasis.

    Full Text Available The San Cristóbal pluton is a 35 km2 granitic body that outcrops at the southestern tip of the Sierra de Velasco, located west of La Rioja city, Argentina. It is formed by monzogranites and syenogranites, together with scarce granodiorites, with medium to fine-grained, equigranular to slightly porphyritic textures. Their mineral assemblage consists of quartz + microcline + plagioclase + biotite ± muscovite + zircon + apatite + magnetite. The granite contains dioritic to tonalitic mafic enclaves. The central and eastern parts of the granite have been deformed by the NNW-SSE trending South Mylonitic shear zone formed by mylonitic rocks. The metamorphic host-rock is represented by scarce greenschist facies xenoliths and hornfels with the high T / P assemblage K-feldspar - cordierite - biotite ± sillimanite. The granites are calc-alkaline, weak- to moderately peraluminous, and formed as part of a continental magmatic arc developed along the active margin of western Gondwana during the Early Paleozoic. The depth of emplacement of the San Cristóbal pluton is estimated at ~12 km.

    Full Text Available El bajo peso al nacer (BPN ha constituido un enigma en la ciencia a través de los tiempos. Múltiples son las investigaciones realizadas acerca de las causas que lo producen y las consecuencias que provoca. Su importancia no solo radica en lo que significa en la morbilidad y la mortalidad infantil, sino que estos niños tienen habitualmente múltiples problemas posteriores. El Programa para la Reducción del BPN señala que los niños nacidos con un peso inferior a los 2 500 g presentan riesgo de mortalidad 14 veces mayor durante el primer año de vida, en comparación con los niños que nacen con un peso normal a término. Dentro de los factores de riesgo del BPN se han encontrado con mayor frecuencia en estudios realizados por diferentes autores, los siguientes: el embarazo en la adolescencia, la desnutrición en la madre, el hábito de fumar, la hipertensión arterial durante el embarazo, la sepsis cervicovaginal, la anemia y los embarazos gemelares, entre otros. Es innegable la influencia que el BPN tiene sobre las futuras generaciones, por lo que debe constituir la diana de los esfuerzos que el médico y la enfermera deben desarrollar en su prevención, sobre todo en la comunidadLow birth weight has been an enigma for Science through times. A lot of research works have been carried out about its causes and consequences. The importance of LBW not only lies in its meaning for infant mortality and morbidity but also in the many problems that low birth weight children regularly face in the future. The program for the reduction of LBW points out that newborns weighing under 2500g have during his/her first year of life a mortality risk 14 times higher than newborns with a normal weight at term. Among the low birth weight risk factors, a number of studies by various authors have frequently found the following; pregnancy at adolescence; undernourishment in mothers, smoking, blood hypertension during pregnancy, cervix-vaginal sepsis; anemia, twin

    Mit Anbruch der Moderne hat sich die Architektur bewußt von den Stilen vorangegangener Epochen losgesagt und sich fortan als Ausdruck einer neuen Kultur, eines neuen Zeitgeistes legitimiert. Der Philosoph Konrad Ott setzt sich mit dem Spannungsfeld zwischen den humanistischen und ästhetischen Ansprüchen der modernen Architektur, wie sie etwa von LeCorbusier formuliert worden sind, und der Realität, die sich etwa in der "Behältnis-Architektur" der Großstädte zeigt, auseinander.

    2018-06-01

    A method named 'matrix exchange' to synthesize ZrAl3 and AlN reinforced Mg-Al composite was developed in this paper. By inserting Al-10ZrN master alloy into Mg matrix and reheating the cooled ingot to 550 °C, Al and Mg atoms diffuse to the opposite side. As a result, liquid melt occurs once the interface areas reach to proper compositions. Then dissolved Al atoms react with ZrN, leading to the in-situ formation of ZrAl3 and AlN particles, while the Al matrix is finally replaced by Mg. This study provides a new insight for preparing Mg composites.

A produção de mudas no viveiro utilizou saco plástico de 1.178 cm3 e tubetes de 120 e 180 cm3 preenchidos com substrato comercial. As mensurações quinzenais incluíram os incrementos em altura, diâmetro do coleto e área foliar. Após o plantio foram avaliados os incrementos no número de folhas, de ramificações e a porcentagem de sobrevivência trimestral. Ao final da fase de viveiro, o maior incremento em altura (1,56 cm e em diâmetro do coleto (1,3 mm foi obtido nas mudas de J. curcas conduzidas em saco plástico com volume de 1.178 cm3, enquanto que os valores para mudas em tubetes de 180 cm3 e 120 cm3 resultaram em 1,24 cm e 1,2 mm e 1,48 cm e 1,1 mm, respectivamente. Após o plantio, não foram verificadas diferenças nos incrementos trimestrais em altura, diâmetro de colo, número de folhas, número de ramos (primários e secundários e porcentagem de mortalidade em função do volume dos recipientes utilizados para a formação das mudas. Os incrementos observados no primeiro trimestre após o plantio apresentaram os maiores valores em diâmetro do coleto, número de folhas, e mortalidade. Mudas de J.curcas semeadas no final de agosto, conduzidas em viveiro de setembro a novembro em tubetes de 120 cm3, e plantadas em dezembro em solo PVd da região oeste do Estado do Paraná resultam em crescimento equivalente ao de mudas produzidas em recipientes de maior volume com economia de substrato, espaço de viveiro e esforço no plantio.

O presente estudo tem como objetivo relatar a utilização da “vacina-do-sapo” por populações não-indígenas em Espigão do Oeste (Rondônia. Foram entrevistadas 31 pessoas que receberam aplicações dessa vacina. A utilização da “vacina-do-sapo” em Espigão do Oeste não se trata de um hábito tradicional da região, sendo que o aplicador veio de outra parte da Amazônia. Em geral, as pessoas que utilizaram a vacina são de classe média a alta e apresentam algum nível de escolaridade (ensino fundamental, médio ou superior. Cerca de metade dos entrevistados acharam que as aplicações ajudaram no problema de saúde que as levaram a receber a vacina ou sentiram melhor disposição após o tratamento e fariam novamente as aplicações. A maioria das pessoas não conhece a espécie P. bicolor, da qual são retiradas as secreções para elaboração da vacina. Embora várias pessoas tenham procurado o tratamento achando que a vacina servia para tudo, suas propriedades medicinais ainda se encontram em estudo.

Se trata de tres fuentes de vulcanitas intensamente explotadas a lo largo de la secuencia prehispánica del área. De esta forma, se toma a las canteras no sólo como un depósito de rocas útiles para la subsistencia, sino como un escenario social donde confluyen y se materializan diferentes prácticas y expresiones sociales. Así, a la explotación de las rocas se suman toda una serie de tareas vinculadas, por ejemplo, con prácticas de enseñanza/aprendizaje y actividades de subsistencia, procesamiento/consumo y rituales. Esta aproximación considera a las canteras desde una perspectiva orientada a abordar las elecciones y prácticas llevadas a cabo por los agentes en contextos de aprovisionamiento, partiendo de la base de que estos actúan desarrollando una diversidad de actividades conectadas en torno a la apropiación de un recurso específico.Abstract  Quarries and workshops at Punta de la Peña, Quebrada Seca and Pampa Oeste (Antofagasta de la Sierra, Catamarca are considered in this paper. The goal is to explore the multiplicity of social activities and practices involved in the use of these quarries. These three vulcanite sources were intensively exploited during the pre-Hispanic history of the region. In this way, quarries are not only considered rock deposits useful for subsistence, but also a social scenario where different social practices and social expressions converge and are materialized. Thereby, series of linked tasks are added to rock exploitation. For example, teaching/learning practices and subsistence, processing/consumption and ritual activities.

    Señores doctores:

    Con toda consideración y respeto me permito agregar algunas anotaciones al escrito del Académico Alberto Cárdenas Escobar, aparecido en el No. 22 de Medicina, para destacar algunos aspectos de la personalidad del doctor Alberto Schweitzer galardonado con el Premio Nobel de la Paz.

    A los 30 años de edad tomó una decisión dramática: Estudiar Medicina para trabajaren el África Ecuatorial. Cuando terminó sus investigaciones sobre enfermedades tropicales y sus prácticas hospitaLarias, partió para el Gabon al pequeño pueblo de Lambarené. La tarea era desconsoladora; La atención médica había que prestarla al aire libre; iba con su esposa, como enfermera y amanuense, y no se encontraba ni un intérprete, ni un ayudante. Cuando le llegaron la medicina y el equipaje hubo que acomodarlos en un viejo gallinero abandonado; el calor era insoportable y le venían enfermos de varias millas a la redonda, a pie o en Canoas.

    Las enfermedades más difundidas eran Malaria, Disentería, estreptococias y la más mortífera, la Tripanosomiasis Gambiense, para la que empezaban a llegar medicinas nuevas eficaces y las medidas preventivas como el suministro de agua potable y enmallado de ventanas impedían muchas contaminaciones.

    Pero la que causaba mayores dificultades y trabajo era la Mycobacteriasis Anestesiante, incurable, de difícil diagnóstico, afectando a varios miembros de la misma familia, de aspecto horripilante, con complicaciones neuríticas muy dolorosas, frecuente ceguera, e invalideces y procesos erisepelatososacrotéricos, que exigían acompañante para el cambio y lavado de vendas y suministro de alimentos.

When some experts of UIN Walisongo from various disciplines try to understand the sacred words of these two resources, their understanding continues, reaching the paradigm of the unity of science which essentially unites the normative, social, and natural sciences. The effect of this paradigm has brought up an issue for the author. Is there any hadiths or Prophetic traditions that can be used as a grand theory in the management disciplines of Islamic education.To address this issue, the authors conducted a literature research with the title Development of Islamic Education Management Module. Sources of data were focused on nine books of Hadiths : Sahih al-Bukhari, Sahih al-Muslim, Sunan Abu Dawud, Sunan at-Turmudzi, Sunan an-Nasai, Sunan Ibn Majah, Sunan ad-Darimi, Muwatta Malik, and Musnad Imam Ahmad bin Hanbal in the form of digital data Lidwa Reader Software Book 9 Imam Hadith.

    Multiple mechanisms could lead to up-regulation of dry-season photosynthesis in Amazon forests, including canopy phenology and illumination geometry. We specifically tested two mechanisms for phenology-driven changes in Amazon forests during dry-season months, and the combined evidence from passive optical and lidar satellite data was incompatible with large net changes in canopy leaf area or leaf reflectance suggested by previous studies. We therefore hypothesized that seasonal changes in the fraction of sunlit and shaded canopies, one aspect of bidirectional reflectance effects in Moderate Resolution Imaging Spectroradiometer (MODIS) data, could alter light availability for dry-season photosynthesis and the photosynthetic capacity of Amazon forests without large net changes in canopy composition. Subsequent work supports the hypothesis that seasonal changes in illumination geometry and diffuse light regulate light saturation in Amazon forests. These studies clarify the physical mechanisms that govern light availability in Amazon forests from seasonal variability in direct and diffuse illumination. Previously, in the debate over light limitation of Amazon forest productivity, seasonal changes in the distribution of light within complex Amazon forest canopies were confounded with dry-season increases in total incoming photosynthetically active radiation. In the accompanying Comment, Saleska et al. do not fully account for this confounding effect of forest structure on photosynthetic capacity.

    At Lawrence Berkeley Laboratory's (LBL) Advanced Light Source (ALS), three 4.6 m long undulators have been completed, tested and installed. A fourth is under construction. The completed undulators include two 5.0 cm period length, 89 period devices (U5.0s) which achieve a 0.85 T effective field at a 14 mm minimum gap and a 8.0 cm period length, 55 period device (U8.0) that reaches a 1.2 T effective field at a 14 mm minimum gap. The undulator under construction is a 10.0 cm period length, 43 period device (U10.0) that is designed to achieve 0.98 T at a 23 mm gap. Undulator magnetic gap variation (rms) is within 25 microns over the periodic structure length. Reproducibility of the adjustable magnetic gap has been measured to be within +/- 5 microns. Gap adjusting range is from 14 mm to 210 mm, which can be scanned in one minute. The 5.1 m long vacuum chambers are flat in the vertical direction to within 0.74 mm and straight in the horizontal direction to within 0.08 mm over the 4.6 m magnetic structure sections. Vacuum chamber base pressures after UHV beam conditioning are. in the mid 10 -11 Torr range and storage ring operating pressures with full current are in the low 10 -10 Torr range. Measurements show that the uncorrelated magnetic field errors are 0.23%, and 0.20% for the two U5.Os and the U8.0 respectively and that the field integrals are small over the 1 cm by 6 cm beam aperture. Device description, fabrication, and measurements are presented

  11. Diffusion-induced quadrupole relaxation of 27Al nuclei in dilute Al-Ti, Al-Cr, Al-Mn, and Al-Cu alloys at high temperatures

    The temperature dependence of the laboratory frame spin-lattice relaxation time of 27 Al nuclei is measured in 5N Al and in dilute Al-Ti, Al-Cr, Al-Mn, and Al-Cu alloys at 5.7 and 9.7 MHz resonance frequencies. The relaxation in pure aluminium is found to be purely due to the conduction electrons. An excess T 1 -relaxation contribution is detected in all Al-3d alloys investigated above 670 K. The excess relaxation rate is proportional to the impurity content and the temperature dependence of the excess contribution is of Arrhenius-type with an activation energy of (1.3 +- 0.3) eV for all of the investigated alloys. The relaxation contribution is found to be quadrupolar in origin and is caused by the relative diffusional jumps of solute atoms and Al atoms relatively far from the impurity. (author)

  12. Deformation mechanisms of nanotwinned Al

    The objective of this project is to investigate the role of different types of layer interfaces on the formation of high density stacking fault (SF) in Al in Al/fcc multilayers, and understand the corresponding deformation mechanisms of the films. Stacking faults or twins can be intentionally introduced (via growth) into certain fcc metals with low stacking fault energy (such as Cu, Ag and 330 stainless steels) to achieve high strength, high ductility, superior thermal stability and good electrical conductivity. However it is still a major challenge to synthesize these types of defects into metals with high stacking fault energy, such as Al. Although deformation twins have been observed in some nanocrystalline Al powders by low temperature, high strain rate cryomilling or in Al at the edge of crack tip or indentation (with the assistance of high stress intensity factor), these deformation techniques typically introduce twins sporadically and the control of deformation twin density in Al is still not feasible. This project is designed to test the following hypotheses: (1) Certain type of layer interfaces may assist the formation of SF in Al, (2) Al with high density SF may have deformation mechanisms drastically different from those of coarse-grained Al and nanotwinned Cu. To test these hypotheses, we have performed the following tasks: (i) Investigate the influence of layer interfaces, stresses and deposition parameters on the formation and density of SF in Al. (ii) Understand the role of SF on the deformation behavior of Al. In situ nanoindentation experiments will be performed to probe deformation mechanisms in Al. The major findings related to the formation mechanism of twins and mechanical behavior of nanotwinned metals include the followings: 1) Our studies show that nanotwins can be introduced into metals with high stacking fault energy, in drastic contrast to the general anticipation. 2) We show two strategies that can effectively introduce growth twins in

    Full Text Available RESUMEN: La dependencia o adicción a sustancias de uso profesional es un problema que puede afectar gravemente a médicos de diferentes especialidades. En la anestesiología hay mayor riesgo de dependencia a opioides e hipnóticos que en otras especialidades y puede llegar a afectar al 1% de los médicos anestesiólogos.La fisiopatología del trastorno por uso de sustancias tiene hechos comunes para diferentes drogas. Interactúan la vulnerabilidad genética y factores psicosociales como predisponentes y los efectos psicobiológicos de la sustancia como factor gatillante. En el caso de los anestesiólogos, la sustancia se encuentra en el lugar de trabajo y por lo tanto, el individuo está constantemente expuesto.Una disfunción previa del sistema de recompensa en el circuito mesocorticolímbico o causada por la exposición a la sustancia adictiva es la piedra central de la neurobiología de las adicciones. Los opioides, anfetaminas, canabinoides, alcohol y nicotina, son algunas de las sustancias exógenas que activan el circuito y causan inicialmente un efecto hedónico que reforzará la conducta por repetir la experiencia. Con el tiempo la interacción con la droga será para evitar los síntomas de abstinencia.Dada la exposición laboral de los anestesiólogos, es necesario prevenir, detectar y tratar precozmente a quienes están abusando de sustancias durante su ejercicio profesional.Por las características de estos fármacos, aspectos psicológicos especiales de los médicos y el contexto laboral se hace necesario un tratamiento especializado y en anestesiólogos la reinserción laboral debe ser un proceso controlado, gradual y con un seguimiento prolongado. SUMMARY: Prescription drugs dependence seriously impairs doctors from differents fields of medicine.

Neste sentido, estabeleceu-se uma proposta de compartimentação geomorfológica da bacia hidrográfica do Rio Itu. Como base metodológica do trabalho, utilizou-se a proposta de Ross (1990, 1992, os mapas e as discussões apresentadas por Robaina et. al (2010 no estudo da bacia hidrográfica do Rio Ibicui. No levantamento cartográfico, adotaram-se cartas topográficas 1:50.000, imagens de satélite e trabalhos de campo. Foram determinados os atributos da rede de drenagem, as características do relevo, o substrato geológico e os tipos de solos. A integração dos dados e a compilação dos mapas permitiram a definição dos diferentes níveis taxonômicos. Nos três primeiros níveis de compartimentação, utilizou-se, como base, a bacia hidrográfica do Rio Ibicuí. A partir do quarto nível taxonômico, estabeleceram-se as unidades geomorfológicas especificamente para a bacia hidrográfica do Rio Itu (BHRI, onde foram definidas oito unidades de formas de relevo: Colinas de arenito, Morrotes de arenito, Cornijas de arenito, Rampa alúvio colúvio, Colinas vulcânicas de topo plano, Relevo escarpado, Morrotes de rocha vulcânica e Colinas de rocha vulcânica. No quinto e sexto níveis, são apresentadas as formas das vertentes e as feições características das unidades de relevo, sendo mais frequentes as curvaturas retilíneo-convergentes e as feições de areias e voçorocas. A análise geomorfológica apresenta elementos fundamentais ao gerenciamento do meio e, portanto, é uma ferramenta indispensável ao planejamento ambiental.

    Using of Al and B2O3 powders as starting materials, and Mg-Al alloy as additives, AlB2-Al2O3 composite powders with AlB2 nanowire structures were successfully fabricated via combustion synthesis method in Ar atmosphere at a pressure of 1.5 MPa. The effect of different amount of Mg-Al alloy on the phase compositions and morphology of the combustion products was investigated. The results revealed that AlB2 and Al2O3 increased, whereas Al decreased with the content of Mg-Al alloy increasing. The impurities MgAl2O4 and AlB12 would exist in the sample with adding of 18 wt% Mg-Al alloy. Interestingly, FESEM/TEM/EDS results showed that AlB2 nanowires were observed in the products when the content of Mg-Al alloy is 6 wt% and 12 wt%. The more AlB2 nanowires can be found as the content of Mg-Al alloy increased. And the yield of AlB2 nanowires with the diameter of about 200 nanometers (nm) and the length up to several tens of micrometers (μm) in the combustion product is highest when the content of Mg-Al alloy is 12 wt%. The vapor, such as Mg-Al (g), B2O2 (g), AlO (g) and Al2O (g), produced during the process of combustion synthesis, reacted with each other to yield AlB2 nanowires by vapor-solid (VS) mechanism and the corresponding model was also proposed.

And one of the most influential figures whose thought which has Sufi religious pattern has dominated educational thinking atmosphere over the centuries since his death. The purpose of education according to al-Ghazali was to get closer to Allah. He came with a view that the most noble job is to educate: to become a teacher. Al-Ghazali advised that his students, in the learning process, aim to become scientists who could disseminate their knowledge for the sake of humanity values.

    Because flake-like TiAl{sub 3} particles in Al-Ti-C master alloys prepared in a melt reaction method dissolve slowly when they are added into Al melt at 720 deg. C, Ti atoms cannot be released rapidly to play the assistant role of grain refinement, leading to a poor refinement efficiency of Al-Ti-C master alloys. A united refinement technology by Al-10Ti and Al-Ti-C master alloys was put forward in this paper. The rational combination of fine blocky TiAl{sub 3} particles in Al-10Ti and TiC particles in Al-Ti-C can improve the nucleation rate of {alpha}-Al. It not only improves the grain refinement efficiency of Al-Ti-C master alloys, but also reduces the consumption.

    AlN/Al dual protective coatings were prepared on NdFeB by DC magnetron sputtering in a home-made industrial apparatus. Comparing with Al coating, AlN/Al coatings have a denser structure of an outmost AlN amorphous layer following an inner Al columnar crystal layer. The coatings and NdFeB substrate combine well, and moreover, there is occurrence of metallurgy bonding in the interface layer. Both Al and AlN/Al coatings have a good protective ability to NdFeB. Especially, the corrosion resistance of AlN/Al coated NdFeB is improved largely. AlN/Al and Al protective coatings not only do not deteriorate the magnetic properties of NdFeB, but contribute to their slight increase.

    Magnetoresistance and rectification are two fundamental physical properties of heterojunctions and respectively have wide applications in spintronics devices. Being different from the well known various magnetoresistance effects, here we report a brand new large magnetoresistance that can be regarded as rectification magnetoresistance: the application of a pure small sinusoidal alternating-current to the nonmagnetic Al/Ge Schottky heterojunctions can generate a significant direct-current voltage, and this rectification voltage strongly varies with the external magnetic field. We find that the rectification magnetoresistance in Al/Ge Schottky heterojunctions is as large as 250% at room temperature, which is greatly enhanced as compared with the conventional magnetoresistance of 70%. The findings of rectification magnetoresistance open the way to the new nonmagnetic Ge-based spintronics devices of large rectification magnetoresistance at ambient temperature under the alternating-current due to the simultaneous implementation of the rectification and magnetoresistance in the same devices.

    Full Text Available Focusing on the field sciences during the late nineteenth and early twentieth centuries, this paper analyzes how railroads served as tools of knowledge empire in the American West. The political economy of this region, shaped by the rise of Populism and capitalist development with federal and state government support, provided the context for cooperation between field scientists and railroad companies. Early on, the displacement of American Indians and their concentration on reservations was intertwined with the research of the Bureau of Ethnology under John Wesley Powell. Later, railroad companies became important patrons of field research, primarily through their provision of free or reduced-fare passes for travel. This research ranged from state universities undertaking research in horticulture and irrigation engineering to metropolitan natural history museums whose field work in paleontology had cultural or symbolic value.Ao analisar pesquisas de campo realizadas no final do século XIX e início do XX, o artigo mostra como as estradas de ferro foram instrumentos do império dos conhecimentos no Oeste dos Estados Unidos.

    Congenital scoliosis (CS) is a common vertebral malformation with incidence of up to 1 of 1000 births worldwide. Recently, TBX6 has been reported as the first disease gene for CS: about 10% of CS patients are compound heterozygotes of rare null mutations and a common haplotype composed by 3 SNPs in TBX6. Lefebvre et al in this journal reported that 2 patients with spondylocostal dysostosis (SCD), a rare skeletal dysplasia affecting spine and ribs also have TBX6 mutations: 1 carried the microdeletion and a rare missense variant, and another 2 rare missense variants. We investigated the pathogenicity of the 3 missense variants in SCD by a luciferase assay. The results were negative for the proposal of Lefebvre et al. We consider these 2 SCD patients are more probably compound heterozygotes of null mutations and a common risk haplotype just as CS patients with TBX6 mutations. © 2017 John Wiley & Sons A/S.

    The oxide phases formed on an Al-deposited Fe-Cr-Al alloy foil and an Fe-Cr-Al alloy foil of the same levels of Al and (La+Ce) contents, and their oxidation kinetics have been studied in air at 1173 and 1373 K using TGA, XRD and SEM. Al deposition promotes the growth of metastable aluminas (θ-Al 2 O 3 , γ-Al 2 O 3 ). Scales consisting of θ-Al 2 O 3 and a small amount of α-Al 2 O 3 develop on the Al-deposited foil at 1173 K and exhibit the whisker-type morphology. In the early stage of oxidation at 1373 K, thick scales consisting of θ-Al 2 O 3 and α-Al 2 O 3 grow rapidly on the Al-deposited foil. The transformation from θ-Al 2 O 3 to α-Al 2 O 3 is very fast, and the scales result in only α-Al 2 O 3 . In contrast, α-Al 2 O 3 scales containing a minor amount of FeAl 2 O 4 develop on the alloy foil. The growth rate of α-Al 2 O 3 scales on the Al-deposited foil is smaller than that on the alloy foil and very close to that on NiAl at 1373 K. (orig.)

    Lisovski et al. [1] describe the widely recognized limitations of light-level geolocator data for identifying short-distance latitudinal movements, recommend that caution be used when interpreting such data, intimated that we did not use such caution and argued that environmental shading likely explained the Golden-winged Warbler (Vermivora chrysoptera) movements described in our 2015 report [2] . Lisovski et al. [1] conclude that the bird movements we reported could not be disentangled from estimation error in stationary animals caused by environmental shading. We argue that, to the contrary, these hypotheses can easily be disentangled because the premise that environmental shading caused synchronous and parallel error among geolocators is false. With their assertion that our location estimates could be biased by >3,500 km on a day with no observable local sources of shading, Lisovski et al. [1] have taken a position of incredulity toward all geolocator-based animal movement data published to date.

    Despite knowledge on the molecular basis of amyotrophic lateral sclerosis (ALS) having quickly progressed over the last few years, such discoveries have not yet translated into new therapeutics. With the advancement of stem cell technologies there is hope for stem cell therapeutics as novel treatments for ALS. We discuss in detail the therapeutic potential of different types of stem cells in preclinical and clinical works. Moreover, we address many open questions in clinical translation. SC therapy is a potentially promising new treatment for ALS and the need to better understand how to develop cell-based experimental treatments, and how to implement them in clinical trials, becomes more pressing. Mesenchymal stem cells and neural fetal stem cells have emerged as safe and potentially effective cell types, but there is a need to carry out appropriately designed experimental studies to verify their long-term safety and possibly efficacy. Moreover, the cost-benefit analysis of the results must take into account the quality of life of the patients as a major end point. It is our opinion that a multicenter international clinical program aime d at fine-tuning and coordinating transplantation procedures and protocols is mandatory.

Due to the relatively long beta decay half lives, data were taken in a beam-off mode, resulting in very clean spectra. Total cross sections were calculated and compared with a theoretical model for barrier penetration proposed by C.Y. Wong. Differences between 18 O induced one and two-neutron total transfer reaction cross sections are discussed. (orig.) [de

    To improve the specific strength and stiffness of Al-based composites, AlN/Al nanoparticles were in-situ synthesized by arc plasma evaporation of Al in nitrogen atmosphere and consolidated by hot-pressing to fabricate AlN nanoparticle-reinforced nanocrystalline Al composites (0-39 vol.% AlN). Microstructure characterization shows that AlN nanoparticles homogeneously distribute in the matrix of Al nanocrystalline, which forms atomically bonded interfaces of AlN/Al. The hardness and the elastic modulus of the nanocomposite have been improved dramatically, up to 3.48 GPa and 142 GPa, respectively. Such improvement is believed to result from the grain refinement strengthening and the interface strengthening (load transfer) between the Al matrix and AlN nanoparticles

    Specimens of pure aluminium, aluminium-copper and aluminium-silver have been irradiated with 20 keV helium ions and/or 100 keV aluminium ions and the nature of the damage assessed using transmission electron microscopy. Irradiation with 20 keV helium ions to a dose of 2.7 x 10 15 ions cm -2 results in the formation of interstitial loops and helium gas bubbles. The helium bubbles were detectable only after annealing at a high temperature following irradiation. When the helium preinjected aluminium specimens were irradiated with 100 keV Al + ions to a dose of 84 dpa at temperatures above 150 0 C, voids were observed to form. At a lower dose of 64 dpa, only a high density of dislocation loops was observed. Al-1 wt% Cu alloy containing partially coherent theta' precipitates resists void formation to a considerable extent, and Al-10 wt% Ag alloy containing coherent G.P. zones offers complete resistance to both dislocation loop nucleation and void formation. The experimental results are discussed in the light of the current theories of irradiation induced damage in metals. The importance of the dislocation-sink efficiency for point defects, the gaseous impurity and the alloying elements in determining void formation is highlighted. (author)

    Mössbauer spectroscopy, X-ray diffraction (XRD) measurements, and electron microprobe analysis (EMPA) have been performed on two meteorites named Al-Dalang and Al-Hawashat after identifying their falling sites in the Western region of Sudan. These two meteorites are ordinary chondrites with similar mineralogy. XRD and EMPA show that the two specimens consist of primary olivine, ortho-pyroxene and later crystallising clino-pyroxene as reaction rims against plagioclase. Fe-metal phases are dominated by kamacite (≈6 wt.% Ni) and minor amounts of tetrataenite (≈52 wt.% Ni). Troilite (FeS) and alabandite (MnS) are optically observed as sulphide phases. The Mössbauer measurements at 295 and 78 K are in agreement with the above characterizations, showing at least two paramagnetic doublets which are assigned to olivine and pyroxene and magnetic sextets assigned to kamacite (hyperfine field ≈33.5 T) and troilite FeS (hyperfine field ≈31 T).

    Curiously, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), seemingly disparate neurodegenerative disorders, can be inherited together. Two groups (DeJesus-Hernandez et al. and Renton et al.) show that the long sought after ALS/FTD mutation on chromosomal region 9p is a hexanucleotide expansion in C90RF72. These studies, plus a study on X-linked ALS/FTD, provide molecular starting points for identifying pathways that link ALS and FTD pathogenesis. Copyright © 2011 Elsevier Inc. All rights reserved.

    The modification effect of a new type of Al-P master alloy on Al-24Si alloys was investigated. It is foundthat excellent modification effect can be obtained by the addition of this new type of A1-P master alloy into Al-24Simelt and the average primary Si grain size is decreased below 47 μm from original 225 μm. It is also found that theTiC particles in the melt coming from Al8Ti2C can improve the modification effect of the Al-P master alloy. Whenthe content of TiC particles in the Al-24Si melt is 0.03 %, the improvement reaches the maximum and keeps steadywith increasing content of TiC particles. Modification effect occurs at 50 min after the addition of the Al-P master al-loy and TiC particles, and keeps stable with prolonging holding time.

    Full Text Available The agricultural activity developed in the western region of the state of Santa Catarina generates wealth on the one hand, but on the other it generates environmental degradation and consequently negative impacts for both humans and other forms of life. Considering this, the first objective of the article is to respond how it is possible to internalize the external factors generated by the agricultural sector. In this way two alternate theoretical models for internalization of the external costs are found in literature: Pareto Internalization and Institutional Internalization. The second objective, on the other hand, consists in identifying which type of internalization is best suited for the Western Santa Catarina region under a perspective which is aimed at sustainable development. To respond to this question it was necessary to discuss, theoretically, sustainable development, as well as weak and strong sustainability. Following this, the first option of internalization to be dealt with follows the perspective of a weak sustainability and the second of a strong sustainability.

    The roll bonding technique is one of the most widely used methods to produce metal laminate sheets. Such sheets offer interesting research opportunities for both scientists and engineers. In this paper, we report on an experimental investigation of the 'thickness effect' during laminate rolling for the first time. Using a four-high multifunction rolling mill, Cu/Al/Cu laminate sheets were fabricated with a range of thicknesses (16, 40, 70 and 130 μm) of the Al layer. The thickness of the Cu sheets was a constant 300 μm. After rolling, TEM images show good bonding quality between the Cu and Al layers. However, there are many nanoscale pores in the Al layer. The fraction of nanoscale pores in the Al layer increases with a reduction in the Al layer thickness. The finite element method was used to simulate the Cu/Al/Cu rolling process. The simulation results reveal the effect of the Al layer thickness on the deformation characteristics of the Cu/Al/Cu laminate. Finally, we propose that the size effect of the Al layer thickness during Cu/Al/Cu laminate rolling may offer a method to fabricate 'nanoporous' Al sandwich laminate foils. Such foils can be used in electromagnetic shielding of electrical devices and noisy shielding of building.

    Full Text Available Do paid work activities displace volunteering? A potential explanation from role overload theoryRecent changes in Dutch society might lead to a shortage of volunteers. On the one hand, the demand for volunteers is increasing: in the social welfare domain because of governmental austerity policies and in other domains such as sports because of the higher supervision intensity of activities. On the other hand, the supply of volunteers is likely to decrease as more and more women and older workers are active in the labor market, which reduces the time that is available for volunteering. Role overload theory would suggest that the increasing labor participation rate of certain categories of workers goes along with a decline of participation in voluntary work. The secondary data analysis shows that various role loads (work, care for children living at home are associated with differences in participation in voluntary work. However, while a higher number of contractual work hours and hours spent on work-related training are negatively associated with volunteer work, care for children living at home is positively associated with volunteering. These results provide only limited support for role overload theory.Betaalde arbeid als verdringer van vrijwilligerswerk? Overbelasting als mogelijke verklaringDe afgelopen jaren hebben zich enkele maatschappelijke veranderingen voorgedaan, die wellicht tot schaarste op de Nederlandse vrijwilligersmarkt zouden kunnen leiden. Enerzijds neemt de vraag naar vrijwilligers toe doordat subsidieregelingen versoberen (bijvoorbeeld in zorg en welzijn en de begeleidingsintensiteit in bepaalde organisaties stijgt (bijvoorbeeld in sport. Anderzijds neemt het aanbod van vrijwilligers af doordat vrouwen en ouderen meer en langer op de arbeidsmarkt actief zijn, waardoor minder tijd beschikbaar is voor vrijwilligerswerk.

    The Al-rich part of the Al-Re phase diagram was reinvestigated by scanning and transmission electron microscopy, powder X-ray diffraction and differential thermal analysis. The earlier reported Al 12 Re, Al 6 Re, and Al 11 Re 4 phases were confirmed. Close to the Al 4 Re composition a high-temperature h-Al 4 Re and a low-temperature l-Al 4 Re phase were found to be formed at slightly different compositions. Both exhibited compositional ranges. A new phase was revealed close to the Al 3 Re composition. The Al 11 Re 4 phase is formed congruently at 1650 deg. C, Al 3 Re peritectically at 1610 deg. C, h-Al 4 Re peritectically at 1410 deg. C, l-Al 4 Re peritectically at ∼1000 deg. C, Al 6 Re peritectically at 813 deg. C and Al 12 Re peritectically at 746 deg. C. Finally, the Al 12 Re-(Al) eutectic is formed at 658 deg. C. The Al 3 Re and h-Al 4 Re are decomposed by eutectoid reactions at ∼946 and 833 deg., respectively. The structure of the h-Al 4 Re phase has not yet been clarified, but it is distinctly different from the Al 4 W phase suggested earlier. The structure of l-Al 4 Re was confirmed.

    Highlights: •2DEG and 2DHG coexist in the AlGaN/AlN/GaN/AlGaN DH-structure. •The sheet densities of 2DEG and 2DHG vary with buffer Al content and GaN thickness. •The conditions for the disappearance of 2DHG are discussed. •Increasing buffer Al content provides better electron confinement. •Dislocation scattering is reduced in the DH-structure. -- Abstract: This is a theoretical study of AlGaN/AlN/GaN/AlGaN double heterojunction (DH) structure with AlGaN as buffer layer. Our calculation shows that as the buffer Al content increases, though two-dimensional electron gas (2DEG) sheet density decreases, the channel back-barrier caused by polarization-induced electric field in GaN provides better electron confinement. And under certain conditions the DH-structure shows bipolar characteristics, with an additional two-dimensional hole gas (2DHG) formed at GaN/AlGaN interface. The influence of the buffer Al content and GaN channel thickness on the 2DEG and 2DHG sheet densities are investigated, and the conditions for the disappearance of 2DHG are discussed. Also, the mobility inhibited by dislocation scattering is enhanced in DH-structure due to the enhancement of screening effect of the 2DEG

    The authors discuss the TiAl/Ti 3 Al interfacial misfit dislocations structures investigated by TEM in Ti-45Al alloy and Ti-45Al/TiB 2 composite. For TiAl with c/a = 1.02, only a single set of misfit dislocation arrays are crystallographically possible; these were observed in Ti-45Al alloy. However, the observation of three sets of misfit dislocation arrays in the Ti-45Al/TiB 2 composite suggests that the occupation of octahedral sites in the TiAl structure by excess boron was responsible for a decrease in the c/a ratio leading to an increased fcc character of the TiAl at the TiAl/Ti 3 Al interface

    [figure removed for brevity, see original site] Click on the image for Opportunity's 'Rub al Khali' Panorama (QTVR) This panoramic image, dubbed 'Rub al Khali,' was acquired by NASA's Mars Exploration Rover Opportunity on the plains of Meridiani during the period from the rover's 456th to 464th sols on Mars (May 6 to May 14, 2005). Opportunity was about 2 kilometers (1.2 miles) south of 'Endurance Crater' at a place known informally as 'Purgatory Dune.' The rover was stuck in the dune's deep fine sand for more than a month. 'Rub al Khali' (Arabic translation: 'the empty quarter') was chosen as the name for this panorama because it is the name of a similarly barren, desolate part of the Saudi Arabian desert on Earth. The view spans 360 degrees. It consists of images obtained in 97 individual pointings of the panoramic camera. The camera took images with five camera filters at each pointing. This 22,780-by-6,000-pixel mosaic is an approximately true-color rendering generated using the images acquired through filters admitting light wavelengths of 750, 530, and 480 nanometers. Lighting varied during the nine sols it took to acquire this panorama, resulting in some small image seams within the mosaic. These seams have been smoothed in sky parts of the mosaic to better simulate the vista that a person would see if able to view it all at the same time on Mars. Opportunity's tracks leading back to the north (center of the panorama) are a reminder of the rover's long trek from Endurance Crater. The deep ruts dug by Opportunity's wheels as it became stuck in the sand appear in the foreground. The crest and trough of the last ripple the rover crossed before getting stuck is visible in the center. These wind-formed sand features are only about 10 to 15 centimeters (4 to 6 inches) tall. The crest of the actual ripple where the rover got stuck can be seen just to the right of center. The tracks and a few other places on and near ripple crests can be seen in this color image to

    Full Text Available AIM: The main objective of the study was to evaluate the limnological characteristics of rivers flowing through urban and rural areas in the upper Uruguay River basin in western Santa Catarina (SC, Brazil. METHODS: Sampling sites in the tributaries were selected along the longitudinal gradient and the different use of the soil in adjacent areas. Samples were collected bimonthly from March 2005 to August 2006. The following were analysed: depth, pH, electrical conductivity, dissolved oxygen concentration (DO, water temperature, chemical oxygen demand (COD, total alkalinity, ammonia, nitrite, nitrate and phosphorus were analysed. RESULTS: In most of the rivers analysed, we found a continuum from the spring to the river mouth that was characterised by a gradual increase in electrical conductivity, COD, phosphorus, alkalinity, nitrite and nitrate. However, an alteration from this pattern was found in rivers passing through urban areas. This deviation was due to high organic matter input poured into the rivers from these areas. CONCLUSIONS: Degraded riparian forest was observed along most of the bodies of water, which facilitates the entry of pollutants. Although the studied area suffers from intense farming activity (agriculture and livestock and has the highest concentration of swine livestock in the country, the rivers that were most altered from their natural state were those that were influenced by sewage and industrial effluents from urban development.OBJETIVO: O objetivo desta pesquisa foi avaliar as características limnológicas de rios que atravessam áreas rurais e urbanas na bacia do alto Rio Uruguai no oeste de Santa Catarina, Brasil.

    Full Text Available A construção do granito Lavras é analisada mediante integração de dados geológicos, geofísicos e estruturais originais e compilados, em consonância com a evolução do centro vulcano-plutônico. Esse centro engloba o complexo intrusivo Lavras do Sul e a sequência traquiandesítica da Formação Hilário (604 - 590 Ma, ambos formados em posição de antepaís durante o período pós-colisional da Orogênese Dom Feliciano, no oeste do Escudo Sul-riograndense. A análise de estruturas rúpteis e lineamentos magnéticos indica que o vulcanismo teve início próximo ao colapso dessa orogenia, condicionado por sistemas transtensivos dextrais NW-SE a WNW-ESE que invertem para sinistrais com o relaxamento tectônico. A formação do complexo intrusivo, principiando com a intrusão subvulcânica do monzonito Tapera no norte, acompanhou a inversão no regime de stress regional ao longo de zona de falha N70-75°W que o seciona. Ao final, ocorreu o posicionamento do granito Lavras no sul, o qual possui dimensões modestas (325 km³ e forma tabular (comprimento - L: espessura - E ≈ 3:1 afinando para sul, como deduzido dos dados gravimétricos. Dois domínios composicional-estruturais, equivalentes aos granitos magnesianos centrais (granodiorito e monzogranito e os ferrosos da borda (sienogranito e feldspato alcalino granito, são definidos pela trama ASM (anisotropia de suscetibilidade magnética. Tais dados, aliados aos de estruturas rúpteis, apontam um plutonmulticíclico construído em dois eventos de ressurgência, envolvendo: (1 o lacólito central decorrente do alojamento do granodiorito sob a soleira de monzogranito; e (2 as intrusões anulares de granitos ferrosos, induzidas pela expansão do reservatório epizonal em razão da recarga com magmas máfico-ultramáficos lamprofíricos. O controle estrutural, a distribuição espacial e a associação com diques lamprofíricos corroboram o vínculo da mineralização aurífera com o último

    Full Text Available La planificación de los recursos es un problema trascendental en los países en desarrollo y también en Cuba, por lo que hacer el mejor uso de los presupuestos limitados y de las escasas divisas, es de vital importancia. Planificar las cantidades de medicamentos necesarias, para lograr garantizar una disponibilidad adecuada de estos en todos los niveles de asistencia, es una tarea en la cual intervienen un sinnúmero de factores. El objetivo de este trabajo fue demostrar en qué medida la introducción del enalapril tabletas influyó en el consumo del captopril tabletas, mediante el análisis de los patrones de consumo de los medicamentos inhibidores de la enzima convertidora de angiotensina en el territorio oeste de La Habana entre marzo de 2005 y diciembre de 2009. Para ello se realizó un estudio de utilización de medicamentos de consumo, de tipo descriptivo, observacional y retrospectivo. Se calcularon las DHD (dosis por mil habitantes día. Los resultados de este trabajo demuestran cómo en este grupo hay un desplazamiento del consumo hacia el enalapril. Este es un comportamiento lógico por la comodidad de la administración y la menor incidencia de efectos adversos. Sin embargo, el captopril se mantiene en valores entre 20 y 30 DHD x 1 000 habitantes ya que hay un grupo de pacientes que continúan con este tratamiento y es de elección en la crisis hipertensiva.The planning of resources is a pressing problem in the developing nations including Cuba, hence using restricted budgets and dwindling foreign currencies in the best possible way is a must.

Wenn es keinen klaren Maßstab für Kontroll- und Überwachungspflichten gibt, besteht die Gefahr, dass Strafverfolgungsbehörden die Compliance-Maßnahmen als Maßstab heranziehen und so eine Verschärfung der Pflichten erzeugen. Nach den Regeln des Verbandsverantwortlichkeitsgesetzes schließt im Übrigen das beste Compliance-System nicht zwingend die Verbandsverantwortlichkeit aus, steht aber unter Umständen einem Verfahren gegen den Verband entgegen.

  2. Orientation of Al3Ti platelets in Al-Al3Ti functionally graded material manufactured by centrifugal method

    1997-01-01

    Al-Al 3 Ti functionally graded materials (FGMs) were manufactured by the centrifugal method with a commercial ingot of Al-5 mass% Ti master alloy. The alloy was melted at a liquid/solid coexisting temperature, at which Al 3 Ti remains as a solid, and then it was cast into a thick-walled ring. It was found that the Al-Al 3 Ti functionally graded material can be successfully fabricated by the centrifugal method. It was also found that the volume fraction of the Al 3 Ti can be increased by repetition of the centrifugal method. Since the shape of Al 3 Ti particles in a commercial alloy ingot is that of a platelet, the Al 3 Ti particles are arranged with their platelet planes nearly perpendicular to the radial direction. The orientation effects become stronger when the G number becomes larger. Although the final centrifugal casting was conducted under a very large centrifugal force for the specimen cast three times, the orientation effects were weaker than those in the specimen cast one time. From these observations, it is concluded that the origin of orientation of Al 3 Ti platelets can be attributed to the angular velocity gradient of the melt along the radial direction produced by the difference in the viscosity.

    2007-01-01

    This paper presents dynamics simulation results of diffusion in off-stoichiometric Al-rich Ni 3 Al (Ni 73 Al 27 ) at temperature ranging from 1300 to 1550 K. The interatomic forces are described by the Finnis-Sinclair type N-body potentials. Particular attention is devoted to the effect of the extra 2% of Al atoms sitting on the Ni sublattice as antisite point defects (Al Ni ) on diffusion. Simulation results show that Ni atoms mainly diffuse through the Ni sublattice at the temperatures investigated. Al atoms diffuse via both the intrasublattice and antistructure bridge (ASB) mechanisms. The contribution to Al diffusion from the ASB mechanism decreases at the lower temperature (T Ni ) enhances both Al and Ni diffusion in Ni 73 Al 27 . The Ni-Al coupled diffusion effect is observed and understood at the atomic level for the first time

    In this work, the electrical transport in Al/Al2O3/Al junctions under mechanical stress is investigated in the perspective to use them as strain sensors. The metal/insulator/metal junctions are elaborated with a low temperature process (≤200 °C) fully compatible with CMOS back-end-of-line. The conduction mechanism in the structure is found to be Fowler-Nordheim tunneling, and efforts are made to extract the relevant physical parameters. Gauge factors up to -32.5 were found in the fabricated devices under tensile stress. Finally, theoretical mechanical considerations give strong evidence that strain sensitivity in Al/Al2O3/Al structures originates not only from geometrical deformations but also from the variation of interface barrier height and/or effective electronic mass in the tunneling oxide layer.

    The interfacial phenomena occurring during the contacting of liquid Al-B, Al-Ti-B, and Al-Zr-B melts with KF-AlF 3 liquid fluxes have been investigated by optical examination of quenched metal drops previously immersed in the liquid fluxes. Reactions in the Al-B/KF-AlF 3 system involve the formation of metastable AlB 12 at the metal/flux interface. At high KBF 4 levels in the flux, the AlB 12 is dispersed in the flux and also at low KBF 4 levels in the metal. Reactions in the Al-Ti-B/KF-AlF 3 system involve the formation of TiB 2 , which may be dispersed in either the metal or the flux depending upon the composition of the flux. The results obtained for the Al-Ti-B/NaF-AlF 3 and Al-Zr-B/KF-AlF 3 systems were similar to those observed for the Al-Ti-B/KF-AlF 3 system

    Full Text Available Al2O3 particle-reinforced ZL109 composite was prepared by in situ reaction between CuO and Al. The microstructure was observed by means of OM, SEM and TEM. The Al2O3 particles in sub-micron sizes distribute uniformly in the matrix, and the Cu displaced from the in situ reaction forms net-like alloy phases with other alloy elements. The hardness and the tensile strength of the composites at room temperature have a slight increase as compared to that of the matrix. However, the tensile strength at 350 ℃ has reached 90.23 MPa, or 16.92 MPa higher than that of the matrix. The mechanism of the reaction in the CuO/Al system was studied by using of differential scanning calorimetry(DSC and thermodynamic calculation. The reaction between CuO and Al involves two steps. First, CuO reacts with Al to form Cu2O and Al2O3 at the melting temperature of the matrix alloy, and second, Cu2O reacts with Al to form Cu and Al2O3 at a higher temperature. At ZL109 casting temperature of 750–780 ℃, the second step can also take place because of the effect of exothermic reaction of the first step.

    Spray-formed Al-Fe alloys having undergone high-speed deformation were examined under a high-voltage electron microscope. Two types of specimens were examined; one containing fine Al 13 Fe 4 particles, and the other containing large particles. In the former specimen, deformation is found to proceed in three patterns, depending on specimen thickness and strain rate: (1) without deformation of the Al 13 Fe 4 ; (2) breaking of the Al 13 Fe 4 ; or (3) melting of the Al 13 Fe 4 . Local melting is found to alter some of the Al 13 Fe 4 particles, to impart five-fold symmetry in diffraction or an amorphous structure. In the latter specimen, introduction of glide dislocations enabled us to determine a shear system in the mc102 monoclinic c2/m crystal of Al 13 Fe 4 . On the bases of these observations, the mechanism of high-speed deformation is discussed while taking into account the highly stressed and/or heated states of Al 13 Fe 4 embedded in Al matrix

En el prólogo, citando desde Sarton y Ziman en los 70s. hasta Mauro Torres en el 2011 afirmo que, aunque suene extraño, parece como si las Academias florecieran entre las guerras. Tal sucedió con la de Platón, “la máxima institución de enseñanza superior surgida en el mundo”, -al decir de Sartonenmarcada desde las guerras del Peloponeso, hasta el final de la dominación espartana de Atenas en el siglo IV antes de Cristo. Según dichos autores, las Academias han simbolizado una manera de continuar la vida espiritual entre uno y otro conflicto.

    Full Text Available En la Alemania actual, la mayor cualificación profesional de las mujeres procedentes de los Landërs del Este, junto con una intensa corriente migratoria hacia el Oeste -mayoritariamente femenina-, está provocando un importante desequilibrio en el “motor europeo”.  La situación está obligando al Gobierno federal a aplicar medidas de urgencia para evitar un necrosamiento económico y demográfico en la parte oriental del país, que afectaría al crecimiento global. El estudio aquí abordado muestra una relación directa del problema con las políticas sociales desarrolladas en las antiguas República Democrática Alemana y República Federal Alemana; esto es, en la Alemania anterior a la Reunificación.Palabras claves: Economía alemana, Reunificación, Género.__________________________________Abstract:Nowadays, the evidence, in Germany, that women from the ancient Democratic German Republic are better qualified for working than women from the Federal German Republic, in addition with the general tendency of population –most of all female-  to emigrate to the West side of the country, is provoking a complete imbalance of ‘the engine of the European Union’. Therefore, the old East Landers are becoming ‘overloaded’ with male and lower skilled population. This situation, which is being shown by the Press and is obligating the German Government to adopt serious politic measures to resolve it, will result into a necrotic of the rate of economic and population growth if it continues. In order to analyze the origin, factor and consequences of the mentioned issue, this paper studies and compares the historical evolution of social politics applied to women and families in the Democratic German Republic and the Federal German Republic. This approach shows how the result of these politics in the new and reunified order of Germany have a strong relation to the demographic and economic problems that are suffering the East Landers of the

    2006-01-01

    The fabrication of AlN-TiC/Al composites by carbon-and nitrogen-containing gas injection into Al-Mg-Ti melts was studied. It was shown that AlN and TiC particles could be formed by the in situ reaction of mixture gas (N2+C2H2+NH3) with Al-Mg-Ti melts. The condition for the formation of AlN was that the treatment temperature must be higher than 1373 K, and the amounts of AlN and TiC increased with the increase of the treatment temperature and the gas injection time.It was considered that AlN was formed by the direct reaction of Al with nitrogen-containing gas at the interface of the gas bubble and the melt. However, the mechanism of TiC formation is a combination mechanism of solution-precipitation and solid-liquid reaction.

    Full Text Available The addition of 1-butylpyrrolidine to AlCl3 results in the formation of an electrolyte that is suited to Al deposition. The feasibility of electrodepositing Al from the synthesized electrolyte was investigated. Several compositions of AlCl3 and 1-butylpyrrolidine were prepared for this purpose. These mixtures show a different phase behavior at various compositions of AlCl3 and 1-butylpyrrolidine. IR, Raman and NMR spectroscopy were employed to characterize the synthesized liquids. Among the prepared compositions, 1:1.2 mol ratio of 1-butylpyrrolidine:AlCl3 and the upper phase of 1:1.3 mol ratio of 1-butylpyrrolidine:AlCl3 were found to be suitable for Al electrodeposition at room temperature (RT. Uniform and thick (~µm thick layers of Al were obtained on copper at RT. Al deposition occured from the cationic species of AlCl3−xLy+ (where x≤2, y=1–2, and L=1-butylpyrrolidine in this electrolyte. This behavior is contrary to the well investigated classic AlCl3 based ionic liquids, where the deposition of Al occurs mainly from anionic Al2Cl7− ions.

    The successful installation and commissioning of high-field superconducting bend magnets (superbends) in three curved sectors of ALS storage ring was the first time the magnet lattice of an operating synchrotron light source has been retrofitted in this fundamental way. As a result, the ALS now offers an expanded spectral range well into the hard x-ray region without compromising either the number of undulators or their high brightness in the soft x-ray region for which the ALS design was originally optimized. In sum, when the superbend-enhanced ALS started up for user operations in October 2001, it marked the beginning of a new era in its history.

    Despite concerns about the representativeness of patients from ALS tertiary centers as compared to the ALS general population, the extent of referral bias in clinical studies remains largely unknown. Using data from EURALS consortium we aimed to assess nature, extent and impact of referral bias. Four European ALS population-based registries located in Ireland, Piedmont, Puglia, Italy, and Limousin, France, covering 50 million person-years, participated. Demographic and clinic characteristics of ALS patients diagnosed in tertiary referral centers were contrasted with the whole ALS populations enrolled in registries in the same geographical areas. Patients referred to ALS centers were younger (with difference ranging from 1.1 years to 2.4 years), less likely to present a bulbar onset, with a higher proportion of familial antecedents and a longer survival (ranging from 11% to 15%) when compared to the entire ALS population in the same geographic area. A trend for referral bias is present in cohorts drawn from ALS referral centers. The magnitude of the possible referral bias in a particular tertiary center can be estimated through a comparison with ALS patients drawn from registry in the same geographic area. Studies based on clinical cohorts should be cautiously interpreted. The presence of a registry in the same area may improve the complete ascertainment in the referral center.

    2017-01-01

    Preface Amyotrophic lateral sclerosis (ALS) is a progressive and uniformly fatal neurodegenerative disease. A plethora of genetic factors underlying ALS have now been identified that drive motor neuron degeneration, increase susceptibility to the disease, or influence the rate of progression. Emerging themes include dysfunction in RNA metabolism and protein homeostasis, with specific defects in nucleocytoplasmic trafficking, induction of endoplasmic reticulum stress, and impaired dynamics of ribonucleoprotein bodies such as RNA granules that assemble through the process of liquid-liquid phase separation. Extraordinary recent progress in understanding the biology of ALS provides new grounds for optimism that meaningful therapies for ALS will be identified. PMID:27830784

He is Burhan al Islam al Zarnuji with his landmark book Ta’lim al Muta’allim. The conclusion that can be drawn is that al Zarnuji has shades of sufistical view in understanding tarbawi hadith. This can be seen in his understanding of hadith on obligation to seek knowledge (thalab al ilmi faridhatun ‘ala kulli muslimin wa muslimatin, which is interpreted as ilm al hal, the science concerning the condition of the human religious or simplistically said as the religious sciences; and the hadith of intention of studying (innama al a’malu bi al niyyat with the intention for the sake of the hereafter and religion, not mundane. Such an understanding is not something taken for granted, but it can be reinterpreted and perfected in accordance with the spirit of the times of context.

    Full Text Available The concept of the creation of universe offered by Neo-Platonism philosopher such as al-Kindi, al-Farabi, and Ibnu Sina are philosophical concept existed and came as an early moment of development of Islamic philosophy interrelated to God, ultimately about his Existence and Characteristics. One of the topics is how God created the universe. According to al-Farabi and Ibnu Sina, God created this universe by way of emanation in order to prevent Himself from the new attitudes. Consequently, universe has eternal feature (qadim as God as well, in the case of everything overflowed from qadim is also qadim. Al-Ghazali refuted this theory because it contradicted with al Qur’an’s thought which clearly explained that God created the entire universe. The universe should not qadim and it means that God existed in the first, and then created universe later as we know today. On the contrary, in the view of Muslim philosopher, the universe should be qadim because God created it from all eternity. For them, it is impossible that God existed by Himself without any creation before. God, according to them is impossible to be changed, so that is impossible as well if God changed from did not create yet before and then creates. Al-Ghazali persistently opposed the concept of eternity. Al Ghazali saw if this universe is qadim so it is impossible that universe created by God. The concept of qadim will led to the conclusion that universe born by itself, it was not created by God. This critique has been written by al-Ghazali in Tahafut al-Falasifah. This paper will present the concept of eternity which was discussed by al-Farabi and Ibn Sina and al Ghazali’s critique toward it as well.

    This review describes the most common motor neuron disease, ALS. It discusses the diagnosis and evaluation of ALS and the current understanding of its pathophysiology, including new genetic underpinnings of the disease. This article also covers other motor neuron diseases, reviews how to distinguish them from ALS, and discusses their pathophysiology. In this article, the spectrum of cognitive involvement in ALS, new concepts about protein synthesis pathology in the etiology of ALS, and new genetic associations will be covered. This concept has changed over the past 3 to 4 years with the discovery of new genes and genetic processes that may trigger the disease. As of 2014, two-thirds of familial ALS and 10% of sporadic ALS can be explained by genetics. TAR DNA binding protein 43 kDa (TDP-43), for instance, has been shown to cause frontotemporal dementia as well as some cases of familial ALS, and is associated with frontotemporal dysfunction in ALS. The anterior horn cells control all voluntary movement: motor activity, respiratory, speech, and swallowing functions are dependent upon signals from the anterior horn cells. Diseases that damage the anterior horn cells, therefore, have a profound impact. Symptoms of anterior horn cell loss (weakness, falling, choking) lead patients to seek medical attention. Neurologists are the most likely practitioners to recognize and diagnose damage or loss of anterior horn cells. ALS, the prototypical motor neuron disease, demonstrates the impact of this class of disorders. ALS and other motor neuron diseases can represent diagnostic challenges. Neurologists are often called upon to serve as a "medical home" for these patients: coordinating care, arranging for durable medical equipment, and leading discussions about end-of-life care with patients and caregivers. It is important for neurologists to be able to identify motor neuron diseases and to evaluate and treat patients affected by them.

  9. Optical phonon scattering on electronic mobility in Al2O3/AlGaN/AlN/GaN heterostructures

    Considering the built-in electric fields and the two-mode property of transverse optical phonons in AlGaN material, the electronic eigen-energies and wave functions are obtained by solving Schrödinger equation with the finite difference method. The dispersion relations and potentials of the optical phonons are given by the transfer matrix method. The mobility of the two dimensional electron gas influenced by the optical phonons in Al2O3/AlGaN/AlN/GaN heterostructures is investigated based on the theory of Lei-Ting force balance equation. It is found that the scattering from the half-space phonons is the main factor affecting the electronic mobility, and the influence of the other phonons can be ignored. The results show that the mobility decreases with increasing the thicknesses of Al2O3 and AlN layers, but there is no definite relationship between the mobility and the thickness of AlGaN barrier. The mobility is obviously reduced by increasing Al component in AlGaN crystal to show that the effect of ternary mixed crystals is important. It is also found that the mobility increases first and then decreases as the increment of the fixed charges, but decreases always with increasing temperature. The heterostructures constructed here can be good candidates as metal-oxide-semiconductor high-electron-mobility-transistors since they have higher electronic mobility due to the influence from interface phonons weakened by the AlN interlayer.

    The Al-Y phase diagram has been reinvestigated with 16 key alloys over its whole composition range by means of differential thermal analysis, X-ray diffraction, optical microscopy, and scanning electron microscopy with energy dispersive X-ray techniques. The existence of five intermetallic phases, Al 3 Y, Al 2 Y, AlY, Al 2 Y 3 , and AlY 2 , has been confirmed. Al 2 Y and Al 2 Y 3 melt congruently at 1490 ± 2 and 1105 ± 2 deg. C, respectively. Al 3 Y, AlY, and AlY 2 are formed via the peritectic reactions L + Al 2 Y ↔ Al 3 Y at 980 ± 2 deg. C, L + Al 2 Y ↔ AlY at 1138 ± 2 deg. C, and L + Al 2 Y 3 ↔ AlY 2 at 977 ± 2 deg. C, respectively. Three eutectic reactions L ↔ (Al) + Al 3 Y at 637 ± 2 deg. C, L ↔ AlY + Al 2 Y 3 at 1081 ± 2 deg. C, and L ↔ AlY 2 + (αY) at 955 ± 2 deg. C , are observed. The previously reported Al 3 Y 5 , AlY 3 compounds were not found. A revised Al-Y phase diagram is presented mainly based on the present experimental results

    The γ-ray emission associated with the radioactive decay of "2"6Al is one of the key pieces of observational evidence indicating stellar nucleosynthesis is an ongoing process in our Galaxy, and it was the first such radioactivity to be detected. Despite numerous efforts in stellar modeling, observation, nuclear theory, and nuclear experiment over the past four decades, the precise sites and origin of Galactic "2"6Al remain elusive. We explore the present experimental knowledge concerning the destruction of "2"6Al in massive stars. The precise stellar rates of neutron-induced reactions on "2"6Al, such as (n,p) and (n,α), have among the largest impacts on the total "2"6Al yield. Meanwhile, reactions involving the short-lived isomeric state of "2"6Al such as radiative proton capture are highly-uncertain at present. Although we presented on-going experimental work from n TOF at CERN with an "2"6Al target, the present proceeding focuses only on the "2"6Al isomeric radioactive beam production aspect and the first experimental results at CRIB.

    The phase diagram of the Y-Cu-Al system at 820 K has been constructed using X-ray powder diffraction. The existence of earlier known ternary aluminides has been confirmed and their homogeneity regions and atomic distributions in the structures have been determined: YCu 4.6-4.0 Al 7.4-8.0 (ThMn 12 -type R I =0.049), Y 2 Cu 12.0-10.5 Al 5.0-6.5 (Th 2 Zn 17 -type R I =0.092), YCu 1.0-1.1 Al 1.0-0.9 (Fe 2 P-type R I =0.068). It has been shown that the structure of Y(Cu,Al) 3 is characterized by an ordered distribution of the Cu and Al atoms and it should be referred as Ca 3 Cu 2 Al 7 structure type (R I =0.060) besides the PuNi 3 structure type with statistical occupancies of the smaller atoms. At the investigated temperature the compound YCu 1.0-0.25 Al 3.0-3.75 (BaAl 4 -type) was not observed. However, we found the ternary aluminide with composition Y 3 Cu 2.7-2.0 Al 8.3-9.0 and related La 3 Al 11 -type (space group Immm, a=0.4192-0.4228, b=1.2423-1.2557, c=0.9812-0.9895 nm, R I =0.069). The compounds YCu 6.8 Al 4.2 (space group Fddd, Tb(Cu 0.58 Al 0.42 ) 11 -type, a=1.42755, b=1.48587, c=0.65654 nm, R I =0.062) and YCu 6.5 Al 4.5 (space group I4 1 /amd, BaCd 11 -type, a=1.02774, c=0.65838 nm, R I =0.071) have been found and structurally refined for the first time

    Full Text Available This paper critically views the epistemology of Muhammad Abid al Jabiri’s interpretation in his book, Madkhal ila al Quran al Karim. His latest work is projected to make the Quran relevant to mankind today and with certainly critiquing classical Quranic studies that have been constructed by previous scholars. Starting from Arab criticism, which is expected to synergize the gap between Turath and modernity, al Jabiri tried out his theory in the realm of Quranic studies oriented to maintain its originality and interpretation from sectarian influence. Focusing on al Jabiri’s review on the Quran, this paper examines and associates some of the problems with the epistemology of critique in Arab reasoning. Finally, it is inferred that the epistemologic offer of al Jabiri used in Turath is not fully applicable in Quranic studies for several reasons. First, the Quranic studies existed within the chain of sanad in its formation. Secondly, at the application stage, al Jabri often overlooked the sanad and narrations from the companions.

    The density of liquid Al-Fe and Al-Ni binary alloys have been determined over a wide temperature range by a noncontact technique combining electromagnetic levitation and optical dilatometry. The temperature and composition dependences of the density are analysed. A negative excess volume correlates with the negative enthalpy of mixing, compound forming ability and chemical short-range ordering in liquid Al-Fe and Al-Ni alloys. (orig.)

  11. AL(0) in municipal waste incinerator ash

    Disposal of municipal waste is a challenge to society. Waste volume is substantially decreased by incineration but residual ash usually contains a number of toxic components which must be immobilised to insure environmental protection. One element, chromium, is mobile and toxic in its oxidised state as Cr(VI) but it can be reduced to Cr(III) and immobilised. Reduction can be promoted by ash treatment with Fe(0) or Fe(II), but recent evidence shows that at least some Cr(VI) is reduced spontaneously in the ash. Aspects of ash behaviour suggest metallic aluminium as the reducing agent, but no direct evidence of Al(0) has been found until now. We examined filter ash from an energy-producing, municipal-waste incinerator (Vest-forbrænding) near Copenhagen. X-ray diffraction (XRD) identified expected salts of Na, K and Ca such as halite, sylvite, calcite, anhydrite and gypsum as well as quartz, feldspar and some hematite. Wave-dispersive electron microprobe produced elemen-tal maps of the ash; Al-rich areas were analysed quantitatively by comparison with standards. We identified metallic Al particles, averaging 50 to 100 micrometers in di-ameter, often with a fractured, glassy border of aluminum oxide. The particles were porous, explaining fast Cr(VI) reduction and they contained thin exsolution lamellae of Al-alloys of Pb and Cu or Mn, Fe and Ag, which provide clues of the Al(0) origin in the waste. Sometimes Al(0) occurred inside glassy globes of Al2O3. Time-of-flight secondary ion mass spectroscopy (TOF-SIMS) and X-ray photoelectron spectroscopy (XPS) proved that surface Al concentrations on ash particles were below detection, confirming reactivity of the Al(0) bulk. The persistence of reduced Al through the highly oxidising combustion procedure comes as a surprise and is a benefit in the immobilisation of Cr(VI) from municipal-waste incineration residues.

Difratometria de raios X, análise textural, limite de plasticidade e concentração de matéria orgânica foram usadas para caracterizar as amostras. A análise textural mostra que a fração argila variou de 38,2 a 66,3 %, a fração silte de 22,2 a 49,7 % e a fração areia de 3,1 a 34,1 %. A concentração de matéria orgânica varia de 5 a 7 %. Os resultados de difração de raios X mostram que todas as amostras possuem caulinita e muitas delas tem argilas do grupo das esmectitas, argilas interestratificadas e mica. Gibsita, óxidos de ferro e de titânio e quartzo são também identificados. Uma amostra usada para "pintar" potes é rica em goetita. Os resultados indicam que as massas cerâmicas tem alta concentração de argila na sua composição e devem ser misturadas com argila "magra". Caulinita é a fase majoritária em todas as amostras, dando uma boa plasticidade para a produção de tijolos e telhas por extrusão.

    Nonoxide tunnel barriers such as AlN are of interest for magnetic tunnel junctions to avoid the oxidation of the magnetic electrodes. We have investigated the fabrication and properties of thin AlN-based barriers for use in low resistance magnetic tunnel junctions. Electronic, magnetic and structural data of tunnel valves of the form Ta (100 Aa)/PtMn (300 Aa)/CoFe 20 (20 Aa - 25 Aa)/barrier/CoFe 20 (10 - 20 Aa)/NiFe 16 (35 - 40 Aa)/Ta (100 Aa) are presented, where the barrier consists of AlN, AlN x O y or AlN/AlO x with total thicknesses between 8 and 15 Aa. The tunnel junctions were sputter deposited and then lithographically patterned down to 2 x 2μm 2 devices. AlN was deposited by reactive sputtering from an Al target with 20% - 35% N 2 in the Ar sputter gas at room temperature, resulting in stoichiometric growth of AlN x (x=0.50±0.05), as determined by RBS. TEM analysis shows that the as-deposited AlN barrier is crystalline. For AlN barriers and AlN followed by natural O 2 oxidation, we obtain tunnel magnetoresistance >10% with specific junction resistance R j down to 60Ωμm 2 .

    This paper reports the development of novel Sinter-Aluminum-Pulver (SAP)-like Al–AlN nanocomposites via replacing the native Al 2 O 3 thin films on fine Al powder with a large volume fraction of in situ formed nanometric AlN dispersoids. Fine gas-atomized Al powder (d 50 =1.3 µm) compacts were first partially nitrided at 590 °C in flowing nitrogen, controlled by a small addition of Sn (0.3–0.4 wt%), and subsequently consolidated by hot direct extrusion. The resulting Al–AlN composites consisted of submicrometric Al grains reinforced with nanometric AlN dispersoids together with some nanometric Al 2 O 3 dispersoids. An Al–13 vol% AlN nanocomposite fabricated this way achieved exceptional ultimate tensile strength of 227 MPa, yield strength of 195 MPa and Young's modulus of 66 GPa at 300 °C, superior to typical SAP materials and coarse grained Al–AlN composites. In addition, the Al–13 vol% AlN nanocomposite exhibited good thermal stability up to 500 °C. The strengthening mechanism is discussed

    The Beaumont Behavioural Inventory (BBI) is a behavioural proxy report for the assessment of behavioural changes in ALS. This tool has been validated against the FrSBe, a non-ALS-specific behavioural assessment, and further comparison of the BBI against a disease-specific tool was considered. This study cross-validates the BBI against the ALS-FTD-Q. Sixty ALS patients, 8% also meeting criteria for FTD, were recruited. All patients were evaluated using the BBI and the ALS-FTD-Q, completed by a carer. Correlational analysis was performed to assess construct validity. Precision, sensitivity, specificity, and overall accuracy of the BBI when compared to the ALS-FTD-Q, were obtained. The mean score of the whole sample on the BBI was 11.45 ± 13.06. ALS-FTD patients scored significantly higher than non-demented ALS patients (31.6 ± 14.64, 9.62 ± 11.38; p ALS-FTD-Q was observed (r = 0.807, p ALS-FTD-Q. Good construct validity has been further confirmed when the BBI is compared to an ALS-specific tool. Furthermore, the BBI is a more comprehensive behavioural assessment for ALS, as it measures the whole behavioural spectrum in this condition.

    Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) share common clinical, genetic and neuropathological features. Some ALS patients have behavioral/personality changes, which could result in significant obstacles in the care provided by family members and caregivers. An easy screening tool would contribute greatly to the evaluation of these symptoms. We translated the ALS-FTD-Questionnaire, developed in the Netherlands, into Japanese (ALS-FTD-Q-J) and examined the clinimetric properties (internal consistency, construct and clinical validity). Patients with ALS and/or behavioral variant FTD (bvFTD) were evaluated alongside healthy controls in this multicenter study. All ALS patients, regardless of bvFTD status, were further evaluated by the frontal behavioral inventory (FBI) and for frontal/executive function, cognition, anxiety/depression, and motor functions. Data from 146 subjects were analyzed: ALS (92), ALS-bvFTD (6), bvFTD (16), and healthy controls (32). The internal consistency of the ALS-FTD-Q-J was good (Cronbach α=0.92). The ALS-FTD-Q-J showed construct validity as it exhibited a high correlation with the FBI (r=0.79). However, correlations were moderate with anxiety/depression and low with cognitive scales, in contrast to the original report, i.e. a moderate correlation with cognition and a low correlation with anxiety/depression. The ALS-FTD-Q-J discriminated ALS patients from (ALS-)bvFTD patients and controls. Thus, the ALS-FTD-Q-J is useful for evaluating Japanese ALS/FTD patients. Copyright © 2016 Elsevier B.V.

    Al cation is known to induce protein fibrillation and causes several neurodegenerative disorders. We report the spectroscopic, thermodynamic analysis and AFM imaging for the Al cation binding process with human serum albumin (HSA), bovine serum albumin (BSA) and milk beta-lactoglobulin (b-LG) in aqueous solution at physiological pH. Hydrophobicity played a major role in Al-protein interactions with more hydrophobic b-LG forming stronger Al-protein complexes. Thermodynamic parameters ΔS, ΔH and ΔG showed Al-protein bindings occur via hydrophobic and H-bonding contacts for b-LG, while van der Waals and H-bonding interactions prevail in HSA and BSA adducts. AFM clearly indicated that aluminum cations are able to force BSA and b-LG into larger or more robust aggregates than HSA, with HSA 4±0.2 (SE, n=801) proteins per aggregate, for BSA 17±2 (SE, n=148), and for b-LG 12±3 (SE, n=151). Thioflavin T test showed no major protein fibrillation in the presence of Al cation. Al complexation induced major alterations of protein conformations with the order of perturbations b-LG>BSA>HSA.

    The authors have measured the cross-breaking strength of Al and Al-Mg alloys bonded with alumina. Diffusion bonding of Al and Al-Mg alloys requires significantly more bonding time than previously thought to obtain complete bonding. In contrast to previous diffusion bonding studies, fracture morphologies are similar to those obtained in bonds formed by liquid phase reaction; i.e., bonds are as strong or stronger than the ceramic; and fracture tends to propagate in the metal for pure Al and near the interface in the ceramic for the alloys. There are indications that the fracture morphology depends on Mg content and therefore on plasticity in the metal

  8. [Lessons from Guam ALS/PDC study].

    An extraordinarily high incidence of amyotrophic lateral sclerosis (ALS) and parkinsonism-dementia complex (PDC) affecting the native population was discovered on the island of Guam a half century ago. Guam ALS is identical to classic ALS clinically and pathologically while PDC is marked by progressive parkinsonism and dementia. The unusual histological finding in these fetal neurodegenerative diseases is the presence of numerous neurofibrillary tangles in a selective topographic distribution unassociated with senile plaques. There have been remarkable advances in field of age-associated neurodegenerative disease after our initial study of Guam cases. Four noteworthy topics are presented in this communication. 1) Clinically, the coexistence of parkinsonism and dementia was frequently recognized in Parkinson disease and Alzheimer disease. Some other new disease entities characterized by coexistence of parkinsonism and dementia have been reported. These include progressive supranuclear palsy, frontotemporal dementia and parkinsonism linked to chromosome 17. 2) Neuropathologically, abundant neurofibrillary tangles unassociated with senile plaques were demonstrated in many diseases such as aftermath of boxing and tangle-only dementia. Furthermore, tau-positive structures were recognized not only in neurons but in glial cells in certain diseases. Tauopathy is one of the current hot research subjects. 3) Familial aggregation of Guam ALS patients provoked investigation of familial ALS elsewhere. Familial motor neuron disease with SOD1 mutation is the target of worldwide intense investigation at the present time. SOD1 gene mutation is, however, not found in Guam ALS. 4) The most striking findings of the Guam study is the gradual decline in the incidence of ALS on Guam during a quarter century and virtual disappearance of new patients. This may be linked to a remarkable change in environment and life style of the Chamorro population. The etiology of ALS is still unknown and

    Full Text Available 'Al Shabaab, a Somali insurgent with predominantly nationalistic causes (alongside transnational [global Jihad] and Islamic goals made the choice to fight on behalf of Al Qaeda in 2008. The decision to do so contrasted with Al Shabaab’s previous behaviour of actively denying cooperation and distancing itself from Al Qaeda. This study aims to uncover factors that contributed to Al Shabaab’s decision through the use of process-tracing. The results show that Al Shabaab’s declaration of cooperation with Al Qaeda in August 2008 was brought about by a series of events that traced back to four factors: public reactions to the implementation of a Salafi ideology, the shift to a radical leadership, Al Shabaab’s inability to maintain stability in areas under its control and its increasing attacks by Al Shabaab on the Somali public. Al Shabaab pursued cooperation with Al Qaeda after realizing that their nationalistic preference was no longer achievable in the near future.' ' '

    AlGaN epilayers with higher Al-compositions were grown by Metalorganic Chemical Vapor Deposition (MOCVD) on (0001) sapphire. Trimethylgallium (TMGa), trimethylaluminium (TMAl) and NH3 were used as the source precursors for Ga, Al, and N, respectively. A 25 nm AlN nucleation layer was first grown at low-temperature of 590 °C at 300 Torr. Followed, AlxGa1-xN layers were grown at 1080 °C on low-temperature AlN nucleation layers. The heterostructures were characterized by a series of techniques, including x-ray diffraction (XRD), Rutherford backscattering (RBS), photoluminescence (PL), scanning electron microscopy (SEM) and Raman scattering. Precise Al compositions were determined through XRD, RBS, and SEM combined measurements. Room Temperature Raman Scattering spectra shows three major bands from AlGaN alloys, which are AlN-like, A1 longitudinal optical (LO) phonon modes, and E2 transverse optical (TO) band, respectively, plus several peak comes from the substrate. Raman spectral line shape analysis lead to an optical determination of the electrical property free carrier concentration of AlGaN. The optical properties of AlGaN with high Al composition were presented here.

    Structure of epitaxial Al 2O 3 layers formed on NiAl(1 1 0) substrates has been studied by means of reflection high-energy electron diffraction (RHEED). The elucidated structure was compared to the model suggested for 0.5 nm-thick Al 2O 3 layers [K. Müller, H. Lindner, D.M. Zehner, G. Ownby, Verh. Dtsch. Phys. Ges. 25 (1990) 1130; R.M. Jaeger, H. Kuhlenbeck, H.J. Freund, Surf. Sci. 259 (1991) 235]. The stepwise growth of Al 2O 3 film, involving deposition and subsequent oxidation of aluminium onto epitaxial 0.5 nm-thick Al 2O 3 layers, has been investigated. Aluminium was deposited at room temperature, whereas its oxidation took place during annealing at 1070 K. The Al 2O 3 thickness was monitored by means of Auger electron spectroscopy (AES). It was found that Al 2O 3 layer follows the structure of 0.5 nm thick Al 2O 3 film, although a tilting of Al 2O 3(1 1 1) surface plane with respect to NiAl(1 1 0) surface appeared after Al deposition.

    Anelastic creep of pure Al, commercial Al-Cu and a binary Al-Cu alloy has been measured at room temperature by means of a high resolution laser interferometer. The irreversible component of the deformation was also quantified from measurements of the anelastic creep recovery. The dependence of the deformation-time curves on thermal treatment and cold work is analyzed. The mechanisms responsible for the room temperature anelastic creep are discussed. Materials loaded below their elastic limit can present either a pure anelastic behavior (commercial Al-Cu) or additional viscoelastic creep (pure Al, high purity Al-Cu). For commercial Al-Cu, the presence of an irreversible deformation appears to be mainly related to the state of the surface. A viscoelastic after effect has been measured for this alloy after a Cu-electroplating treatment. As a typical result for room temperature creep, the irreversible deformation depends logarithmically on load time. (orig.)

    Objective Autopsy studies show widespread pathology in amyotrophic lateral sclerosis (ALS), but clinical surveys of multisystem disease in ALS are rare. We investigated ALS-Plus syndrome, an understudied group of patients with clinical features extending beyond pyramidal and neuromuscular systems with or without cognitive/behavioral deficits. Methods In a large, consecutively-ascertained cohort of 550 patients with ALS, we documented atypical clinical manifestations. Genetic screening for C9orf72 hexanucleotide expansions was performed in 343 patients, and SOD1, TARDBP, and VCP were tested in the subgroup of patients with a family history of ALS. Gray matter and white matter imaging was available in a subgroup of 30 patients. Results Seventy-five (13.6%) patients were identified with ALS-Plus syndrome. We found disorders of ocular motility, cerebellar, extrapyramidal and autonomic functioning. Relative to those without ALS-Plus, cognitive impairment (8.0% vs 2.9%, p=0.029), bulbar-onset (49.3% vs 23.2%, pALS-Plus. Survival was significantly shorter in ALS-Plus (29.66 months vs 42.50 months, p=0.02), regardless of bulbar-onset or mutation status. Imaging revealed significantly greater cerebellar and cerebral disease in ALS-Plus compared to those without ALS-Plus. Conclusions ALS-Plus syndrome is not uncommon, and the presence of these atypical features is consistent with neuropathological observations that ALS is a multisystem disorder. ALS-Plus syndrome is associated with increased risk for poor survival and the presence of a pathogenic mutation. PMID:25086858

    1992-01-01

    This paper discusses the dislocation structure of small angle tilt and twist boundaries in ordered Ni 3 Al, with and without boron, investigated using transmission electron microscopy. Dislocation with Burgers vectors that correspond to anti-phase boundary (APB)-coupled superpartials were found in small angle twist boundaries in both boron-free and boron-doped Ni 3 Al, and a small angle tilt boundary in boron-doped Ni 3 Al. The boundary structures are in agreement with theoretical models proposed by Marcinkowski and co-workers. The APB energy determined from the dissociation of the grain boundary dislocations was lower than values reported for isolated APBs in Ni 3 Al. For small angle twist boundaries the presence of boron reduced the APB energy at the interface until it approached zero. This is consistent with the structure of these boundaries containing small regions of increased compositional disorder in the first atomic plane next to the interface

  8. In Situ Fabrication of AlN Coating by Reactive Plasma Spraying of Al/AlN Powder

    2011-10-01

    Full Text Available Reactive plasma spraying is a promising technology for the in situ formation of aluminum nitride (AlN coatings. Recently, it became possible to fabricate cubic-AlN-(c-AlN based coatings through reactive plasma spraying of Al powder in an ambient atmosphere. However, it was difficult to fabricate a coating with high AlN content and suitable thickness due to the coalescence of the Al particles. In this study, the influence of using AlN additive (h-AlN to increase the AlN content of the coating and improve the reaction process was investigated. The simple mixing of Al and AlN powders was not suitable for fabricating AlN coatings through reactive plasma spraying. However, it was possible to prepare a homogenously mixed, agglomerated and dispersed Al/AlN mixture (which enabled in-flight interaction between the powder and the surrounding plasma by wet-mixing in a planetary mill. Increasing the AlN content in the mixture prevented coalescence and increased the nitride content gradually. Using 30 to 40 wt% AlN was sufficient to fabricate a thick (more than 200 µm AlN coating with high hardness (approximately 1000 Hv. The AlN additive prevented the coalescence of Al metal and enhanced post-deposition nitriding through N2 plasma irradiation by allowing the nitriding species in the plasma to impinge on a larger Al surface area. Using AlN as a feedstock additive was found to be a suitable method for fabricating AlN coatings by reactive plasma spraying. Moreover, the fabricated coatings consist of hexagonal (h-AlN, c-AlN (rock-salt and zinc-blend phases and certain oxides: aluminum oxynitride (Al5O6N, cubic sphalerite Al23O27N5 (ALON and Al2O3. The zinc-blend c-AlN and ALON phases were attributed to the transformation of the h-AlN feedstock during the reactive plasma spraying. Thus, the zinc-blend c-Al

    To estimate the genetic risk conferred by known amyotrophic lateral sclerosis (ALS)-associated genes to the pathogenesis of sporadic ALS (SALS) using variant allele frequencies combined with predicted variant pathogenicity. Whole exome sequencing and repeat expansion PCR of C9orf72 and ATXN2 were performed on 87 patients of European ancestry with SALS seen at the University of Utah. DNA variants that change the protein coding sequence of 31 ALS-associated genes were annotated to determine which were rare and deleterious as predicted by MetaSVM. The percentage of patients with SALS with a rare and deleterious variant or repeat expansion in an ALS-associated gene was calculated. An odds ratio analysis was performed comparing the burden of ALS-associated genes in patients with SALS vs 324 normal controls. Nineteen rare nonsynonymous variants in an ALS-associated gene, 2 of which were found in 2 different individuals, were identified in 21 patients with SALS. Further, 5 deleterious C9orf72 and 2 ATXN2 repeat expansions were identified. A total of 17.2% of patients with SALS had a rare and deleterious variant or repeat expansion in an ALS-associated gene. The genetic burden of ALS-associated genes in patients with SALS as predicted by MetaSVM was significantly higher than in normal controls. Previous analyses have identified SALS-predisposing variants only in terms of their rarity in normal control populations. By incorporating variant pathogenicity as well as variant frequency, we demonstrated that the genetic risk contributed by these genes for SALS is substantially lower than previous estimates. © 2017 American Academy of Neurology.

    The paper describes thermoluminescence (TL) properties of AlN:Y2O3 ceramics irradiated with ionising radiation. A high TL sensitivity of AlN:Y2O3 ceramics to radiation encouraged a study of the AlN ceramics for application as a dosimetric material. The paper presents experimental data on: glow...... curve, emission spectrum, dose response, energy dependence, influence of heating rate and fading rate. The measured TL characteristics were compared with those of well-known, widely used TLDs, i.e. LiF:Mg,Ti, LiF:Mg,Cu,P and Al2O3:C. It is concluded that AlN:Y2O3 ceramics showing a radiation sensitivity...... which is approximately 50 times greater than that of LiF:Mg,Ti is an interesting dosimetry material; however due to a high fading rate of the TL of AlN:Y2O3 on storage at room temperature, a further development of the material for improving the fading characteristics is needed for its application...

    Owing to uncertainty on the pathogenic mechanisms underlying motor neuron degeneration in amyotrophic lateral sclerosis (ALS) riluzole remains the only available therapy, with only marginal effects on disease survival. Here we review some of the recent advances in the search for disease-modifying drugs for ALS based on their putative neuroprotective effetcs. A number of more or less established agents have recently been investigated also in ALS for their potential role in neuroprotection and relying on antiglutamatergic, antioxidant or antiapoptotic strategies. Among them Talampanel, beta-lactam antibiotics, Coenzyme Q10, and minocycline have been investigated. Progress has also been made in exploiting growth factors for the treatment of ALS, partly due to advances in developing effective delivery systems to the central nervous system. A number of new therapies have also been identified, including a novel class of compounds, such as heat-shock protein co-inducers, which upregulate cell stress responses, and agents promoting autophagy and mitochondriogenesis, such as lithium and rapamycin. More recently, alterations of mRNA processing were described as a pathogenic mechanism in genetically defined forms of ALS, as those related to TDP-43 and FUS-TLS gene mutations. This knowledge is expected to improve our understanding of the pathogenetic mechanism in ALS and developing more effective therapies.

    Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative motor neuron disease accompanied by both systemic and central nervous system-specific inflammation as well as deregulated energy metabolism. These potential pathogenetic factors have recently been found to mutually interact with the gut microbiota, raising the hypothesis of a link between microbiome alterations and ALS pathogenesis. The aim of our study was to assess whether ALS is associated with an altered composition of the fecal microbiota. We compared the fecal microbiota of 25 ALS patients with 32 age- and gender-matched healthy persons using 16S rRNA gene sequencing analysis. Confounding factors and secondary disease effects on the microbiome were minimized by selection of patients without dysphagia, gastrostomy, noninvasive ventilation, or reduced body mass index. Comparing the 2 carefully matched groups, the diversity and the abundance of the bacterial taxa on the different taxonomic levels as well as PICRUSt-predicted metagenomes were almost indistinguishable. Significant differences between ALS patients and healthy controls were only observed with regard to the overall number of microbial species (operational taxonomic units) and in the abundance of uncultured Ruminococcaceae. Conclusively, ALS patients do not exhibit a substantial alteration of the gut microbiota composition. Copyright © 2017 Elsevier Inc. All rights reserved.

    2010-01-01

    It has been known experimentally for some time that Al3 Ti is a powerful nucleant for the solidification of aluminum from the melt; however, a full microscopic understanding is still lacking. To develop this understanding, we have performed molecular dynamics simulations of the nucleation and early stages of growth using published embedded atom method potentials for Al-Ti, but modified by us to stabilize the D 022 structure. We discover that Al3 Ti can indeed be very effective in promoting the growth of solid Al but the manner in which growth takes place depends sensitively on the surface on which the Al nucleates. In particular, complete growth of solid Al from the liquid on the (001) and (110) surfaces of Al3 Ti occurs at a lower temperature than on the (112) surface. This anisotropy agrees with observations in previous experiments. We explain this observation in terms of interfacial energies. On the preferential (111) surface of Al the solid-liquid interfacial energy is highest while the solid-vacuum energy is lowest. Our simulations also show that the extent of ordering taking place in liquid Al close to the Al 3 Ti substrate above the melting point correlates well with the effectiveness of the substrate as a nucleant below the melting temperature: this could provide a computationally efficient scheme to identify good nucleants. © 2010 The American Physical Society.

    Composite materials comprising a porous Ti{sub 2}AlC matrix and Al 6061 alloy were fabricated by a current-activated pressure assisted melt infiltration process. Coarse, medium and fine meso-structures were prepared with Al alloy filled pores of differing sizes. Materials were subjected to uniaxial compressive loading up to stresses of 668 MPa, leading to the failure of specimens through crack propagation in both phases. As-fabricated and post-failure specimens were analysed by X-ray microscopy and electron microscopy. Quasi-static mechanical testing results revealed that compressive strength was the highest in the fine structured composite materials. While the coarse structured specimens exhibited a compressive strength of 80% relative to this. Reconstructed micro-scale X-ray tomography data revealed different crack propagation mechanisms. Large planar shear cracks propagated throughout the fine structured materials while the coarser specimens exhibited networks of branching cracks propagating preferentially along Al alloy-Ti{sub 2}AlC phase interfaces and through shrinkage pores in the Al alloy phase. Results suggest that control of porosity, compensation for Al alloy shrinkage and enhancement of the Al alloy-Ti{sub 2}AlC phase interfaces are key considerations in the design of high performance metal/Ti{sub 2}AlC phase composites.

    The formation of borides in an Al-3 wt.%B master alloy, produced via chemical reactions of KBF 4 and aluminium has been investigated. The chemical reactions produce boron, which dissolves into molten aluminium and subsequently forms aluminium borides. Backscattered electron imaging (BEI) of the Al-3 wt.%B master alloy under a scanning electron microscope (SEM) revealed the presence of two types of phases that contain different levels of boron. Combined with X-ray diffraction (XRD) results, the two types of phases are identified as AlB 2 on AlB 12 . This gives a direct evidence for a peritectic reaction of AlB 12 and aluminium, which produces AlB 2 . The thermodynamic properties of the reactions that may be involved are examined, and the presence of AlB 12 phase in the master alloy explained. The observed microstructure is explained according to the peritectic reaction in an Al-B phase diagram. The stability of AlB 2 and AlB 12 at lower temperature than 975 deg. C is clarified

    Research highlights: → The glass-forming ability of the Al-La and Al-La-Ni systems was studied using the λ* and the λ.Δe criteria. → Both criteria predicted with just 1% at. of error the best glass-former verified so far in the Al-La system. → Four new glass-former compositions could be predicted in the Al-La-Ni system using the λ.Δe criterion. → The best glass-former reported so far in the Al-La-Ni system was found. - Abstract: In this work, a criterion considering the topological instability (λ) and the differences in the electronegativity of the constituent elements (Δe) was applied to the Al-La and Al-Ni-La systems in order to predict the best glass-forming compositions. The results were compared with literature data and with our own experimental data for the Al-La-Ni system. The alloy described in the literature as the best glass former in the Al-La system is located near the point with local maximum for the λ.Δe criterion. A good agreement was found between the predictions of the λ.Δe criterion and literature data in the Al-La-Ni system, with the region of the best glass-forming ability (GFA) and largest supercooled liquid region (ΔT x ) coinciding with the best compositional region for amorphization indicated by the λ.Δe criterion. Four new glassy compositions were found in the Al-La-Ni system, with the best predicted composition presenting the best glass-forming ability observed so far for this system. Although the λ.Δe criterion needs further refinements for completely describe the glass-forming ability in the Al-La and Al-La-Ni systems, the results demonstrated that this criterion is a good tool to predict new glass-forming compositions.

    The system Nb-Cr-Al was investigated in the region near the Al 3 (Nb,Cr) + Cr(Al,Nb) eutectic and the liquidus projection of that region was determined based on the microstructural characterization of arc melted alloys. The characterization utilized scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), differential thermal analysis (DTA) and X-ray diffraction (XRD). The results allowed one to determine three primary solidification liquidus surfaces ((Cr,Al) 2 Nb, Cr(Al,Nb) and Al 3 (Nb,Cr)), that are originated from the binary systems Cr-Nb, Cr-Al and Al-Nb. It is proposed the occurrence of the invariant reaction L + (Cr,Al) 2 Nb ↔ Al 3 (Nb,Cr) + Cr(Al,Nb) and of a point of minimum, which involves a three phase reaction, L ↔ Al 3 (Nb,Cr) + Cr(Al,Nb). All alloys studied showed formation of the Al 3 (Nb,Cr) + Cr(Al,Nb) eutectic as the last solidification step with Al(Nb)Cr 2 precipitating from Cr(Al,Nb)

    Full Text Available Aluminium ion (Al3+ toxicity and hydrogen ion (H+ activity are the major constraints for plant growth in acid soil. This study was undertaken to determine the effect of pH and Al on the growth response and changes in root morphology of Al-tolerant (ET8 and Al-sensitive (ES8 wheat seedlings. Different levels of AlCl3 and CaCO3 were added to the soils to manipulate soil pH and extractable Al. The results showed that the bulk soil pH remained constant at pH 4.1 with further applications of AlCl3, and that the seedlings died at the 200 mg AlCl3/kg treatments. The ET8 seedlings responded better than the ES8 seedlings in both low and high Al and pH. The ET8 seedlings had higher root surface areas and root tip numbers than the ES8 seedlings in the Al treatment. In contrast, the ES8 had higher root diameters than the ET8 seedlings due to the elevated Al supply. Apoplast Al increased with the increase of soil available extractable Al, and declined with the decrease of soil extractable Al. The ET8 seedlings accumulated more Al in their apoplast than the ES8 seedlings. This study concluded that accumulation of Al in the apoplast is also involved in Al tolerance mechanism with the addition of organic acid exudation.

    The disordered crystal structure of 20H-AlON (Al 10 O 3 N 8 ) was determined by combined use of X-ray powder diffraction and transmission electron microscopy. The title compound is hexagonal with space group P6 3 /mmc (Z=2) and the unit-cell dimensions are a=0.307082(5) nm, c=5.29447(8) nm and V=0.432376(12) nm 3 . The structural model showed the positional disordering of three of the six Al sites in the unit cell. The reliability indices calculated from the Rietveld method were R wp =6.97%, S (=R wp /R e )=1.68, R p =5.45%, R B =5.13% and R F =4.56%. We interpreted the disordered structure of 20H-AlON as a statistical average of six different types of ordered structural configurations, which are composed of an octahedral [Al(O, N) 6 ] layer and tetrahedral [Al(O, N) 4 ] layers. We demonstrated the high correlations between the hexagonal unit-cell dimensions and the octahedral layer concentrations for AlON and SiAlON polytypoids. - Graphical abstract: Variations of a and c/(n O +n T ) with n O /(n O +n T ). The a and c are the hexagonal unit-cell dimensions of AlON, SiAlON and AlN. The n O and n T are, respectively, the numbers of octahedral and tetrahedral layers in the unit cells. The unit-cell dimensions in literature are plotted in black plus for AlON and black cross for SiAlON. The unit-cell dimensions of AlN are a=0.3110 nm and c=0.4980 nm. - Highlights: • Crystal structure of Al10O3N8 is determined by laboratory X-ray powder diffraction. • The atom arrangements are represented by the split-atom model. • Six types of ordered atom arrangements are derived from the disordered structure. • Hexagonal unit-cell dimensions changed systematically for AlON and SiAlON compounds

    Full Text Available Abstract: Ilh}a>q al-Masa>’il bi Naz}a>iriha is one of the methods used by Nahdlatul Ulama in resisting the opinion based on (manhaji analytical concept of Islamic jurisprudence (the solution for complex social problems as the main purpose of Islamic shari’ah. As known that, up to now, ilh}a>q has been understood as a process of answering a new case by the way of equating to the old one which is written in the book called al-mu’tabarah. Such ilh}a>q has got many criticisms both from the definitions, procedures and its epistemogical footing. This paper is about to reveal how the NU clerics of Islam understand the concept of Ilh}a>q}, what its epistemological footing was and how the concept was applied in discussing many cases (bah}th al-masa>’il. Based on the writer’s study to several documents of decision results of NU that Ilh}a>q did not only simplify to equate the new cases with the old ones that have been freely discussed in the books of al-mu’tabarah, but both cases should have similar legal substance, that is, both should be under the decrees of laws of al-qawa> ‘id al-fiqhi>yah. Thus, Ilh}a>q is actually answering the problem by applying al-qawa>‘id al-fiqhi>yah, whereas the formulation al-qawa>‘id al-fiqhi>yah itself was set off from the examination of a number of furu>’ generated by qiya> s. This paper also found three variations of the implementation of Ilh}a>q in bah}th al-masa>’il. First, the application of Ilh}a>q was without mentioning al-qawa> ‘id al-fiqhi>yah which covered new cases (mulh}aq and the old case law that has been known in the books of fiqh (mulh}aq bih/attached to. Second, the application of Ilh}a>q was accompanied by mentioning mulh}aq bih and al-qawa> ‘id al-fiqhi>yah. Third, the application of Ilh}a>q, was only by the mentioning al-qawa> ‘id al-fiqhi>yah.

    Full Text Available The impelemtantion of character education that is done by the Indonesian government recently has been provoked by al-Ghazali and Burhanuddin al-Zarnuji long ago. It was proven by some written thoughts of al-Ghazali and Burhanuddin al-Zarnuji. They were very famous scientists in their era and widely welknown as educational experts who produced some phenomenal thoughts many people use today. Al-Ghazali and Burhanuddin al-Zarnuji lived in the era of Bani Abbasiyah monarchy, but Both of them lived in different era. Al-Ghazali was born first, then Burhanuddin al-Zarnuji. They had different mazhab, al-Ghazali went to the traditional principle of mazhab Syafi’I and Burhanuddin al-Zarnuji went to the modern principle of mazhab Hanafi. The differences, of course, would create a different thought. Still, they might have a similar principle of Islamic character education. The thoughts of character education of al-Ghazali have been poured in the “Ayyuha Walad” focusing to the students’ character building characterized by religiously obedient, skillfull of general and religious knowledge, socially helpful, affectionate, generous, good citizen, and coloring the society. Some applicable thoughts of character education of Ayyuha al-Walad of al-Gazhali to the contemporary education are: the balance of the happiness purposes of the recent life and the life after death, qana’ah and tawakal, affectionate, caring other, patience, honesty, philanthrophy, social works, generousity, democratic, peace makers, and patriotic. Those characters are also directed in the islamic character education nowdays. So that, the thoughts of al-Ghazali positively and responsively are absorbed by the Indonesian government to build the national character widely implementing in the national curriculum based on the local wisdom and the Islamic values. In the end, the students are able to live happily based on the Islamic rules by implementing the good behavior. Similar to the al

    The T β/α+β of Zr5Nb and Zr5Nb2Al (weight %) were determined in order to observe the alpha-stabilizer character of Al in ternary Zr-Nb-Al alloys. Techniques employed were change of resistivity with temperature in dynamic experiences, and metallography of samples quenched to room temperature after isothermal annealings. The T β/α+β of the ternary resulted 17 ± 8 deg C higher than that of the binary alloy. In addition, taking into account the results of previous investigations of the transformation of beta on quenching Zr-Nb-Al alloys from the beta field to room temperature, it is concluded that the beta-stabilizer character of Nb is stronger than the alpha-stabilizer character of Al in these Zr alloys, and that the Al can have important influence on the mechanical properties by the appearance of TRIP effect.

    We present 27 Al NMR studies for a single crystal of the Np-based superconductor NpPd 5 Al 2 (T c =4.9K). We have observed a five-line 27 Al NMR spectrum with a center line and four satellite lines separated by first-order nuclear quadrupole splittings. The Knight shift clearly drops below T c . The temperature dependence of the 27 Al nuclear spin-lattice relaxation rate shows no coherence peak below T c , indicating that NpPd 5 Al 2 is an unconventional superconductor with an anisotropic gap. The analysis of the present NMR data provides evidence for strong-coupling d-wave superconductivity in NpPd 5 Al 2 .

    Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting motor neurons of the brain and spinal cord, leading to progressive paralysis and death. Interestingly, many skin changes have been reported in ALS patients, but never as yet fully explained. These observations could be due to the common embryonic origin of the skin and neural tissue known as the ectodermal germ layer. Following the first observation in ALS patients' skin by Dr Charcot in the 19th century, in the absence of bedsores unlike other bedridden patients, other morphological and molecular changes have been observed. Thus, the skin could be of interest in the study of ALS and other neurodegenerative diseases. This review summarizes skin changes reported in the literature over the years and discusses about a novel in vitro ALS tissue-engineered skin model, derived from patients, for the study of ALS.

    Highlights: • Diffusion and gradual solid reactions between Al and Fe{sub x}P phases in Al-Fe-P alloy were investigated. • Nanoscale AlP clusters are in-situ generated and evolve during the whole process. • This novel Al-Fe-P alloy has an excellent low-temperature refining performance on hypereutectic Al-Si alloy. - Abstract: In this paper, the gradual solid reactions between Al and Fe{sub x}P phases in Al-Fe-P alloy were investigated. The results show that the whole reaction process undergoes four main stages: the diffusion of Al atom, the generation of (Al, Fe, P) intermediate compound, the precipitation of nano AlP and Al{sub 13}Fe{sub 4} clusters and their growth to submicron particles. The microstructure of Fe-P particles evolves from the “egg-type”, the “sponge-type” to the “sesame-cake” structure. AlP and Al{sub 13}Fe{sub 4} nano phases have in-situ generated and evolved during the whole process. The gradual reaction mechanism has been discussed. Furthermore, a novel Al-Fe-P alloy which contains (Al, Fe, P) intermediate compounds and nano AlP particles has been synthesized and its low-temperature refining performance on A390 alloy has also been investigated.

    Full Text Available Based on the idea of alloying welding seams, a series of Zn–xAl filler metals was calculated and designed for joining Mg/Al dissimilar metals by gas tungsten arc (GTA welding. An infrared thermography system was used to measure the temperature of the welding pool during the welding process to investigate the solidification process. It was found that the mechanical properties of the welded joints were improved with the increasing of the Al content in the Zn–xAl filler metals, and when Zn–30Al was used as the filler metal, the ultimate tensile strength could reach a maximum of 120 MPa. The reason for the average tensile strength of the joint increasing was that the weak zone of the joint using Zn–30Al filler metal was generated primarily by α-Al instead of MgZn2. When Zn–40Al was used as the filler metal, a new transition zone, about 20 μm-wide, appeared in the edge of the fusion zone near the Mg base metal. Due to the transition zones consisting of MgZn2- and Al-based solid solution, the mechanical property of the joints was deteriorated.

    Out-of-hospital emergency physicians in Austria need mandatory emergency physician training, followed by biennial refresher courses. Currently, both standardized ERC advanced life support (ALS) provider courses and conventional refresher courses are offered. This study aimed to compare the retention of ALS-knowledge of out-of-hospital emergency physicians depending on whether they had or had not participated in an ERC-ALS provider course since 2005. Participants (n=807) from 19 refresher courses for out-of-hospital emergency physicians answered eight multiple-choice questions (MCQ) about ALS based on the 2005 ERC guidelines. The pass score was 75% correct answers. A multivariate logistic regression analyzed differences in passing scores between those who had previously participated in an ERC-ALS provider course and those who had not. Age, gender, regularity of working as an out-of-hospital emergency physician and the self-reported number of real resuscitation efforts within the last 6months were entered as control variables. Out-of-hospital emergency physicians who had previously attended an ERC-ALS provider course had a significantly higher chance of passing the MCQ test (OR=1.60, p=0.015). Younger age (OR=0.95, pERC-ALS provider course since 2005 had a higher retention of ALS knowledge compared to non-ERC-ALS course participants. Copyright © 2011 Elsevier Ireland Ltd.

    Tris(8-hydroxyquinoline)aluminum(III), AlQ3, is used in organic light-emitting diodes (OLEDs) as an electron-transport material and emitting layer. The reaction of AlQ3 with trace H2O has been implicated as a major failure pathway for AlQ3-based OLEDs. Hybrid density functional calculations have been carried out to characterize the hydrolysis of AlQ3. The thermochemical and atomistic details for this important reaction are reported for both the neutral and oxidized AlQ3/AlQ3+ systems. In support of experimental conclusions, the neutral hydrolysis reaction pathway is found to be a thermally activated process, having a classical barrier height of 24.2 kcal mol(-1). First-principles infrared and electronic absorption spectra are compared to further characterize AlQ3 and the hydrolysis pathway product, AlQ2OH. The activation energy for the cationic AlQ3 hydrolysis pathway is found to be 8.5 kcal mol(-1) lower than for the neutral reaction, which is significant since it suggests a role for charge imbalance in promoting chemical failure modes in OLED devices.

  1. Al-matrix composite materials reinforced by Al-Cu-Fe particles

    Al-matrix material composites were produced using hot isostatic pressing technique, starting with pure Al and icosahedral (i) Al-Cu-Fe powders. Depending on the processing temperature, the final reinforcement particles are either still of the initial i-phase or transformed into the tetragonal ω-Al0 0.70 Cu 0.20 Fe 0.10 crystalline phase. Compression tests performed in the temperature range 293K - 823K on the two types of composite, i.e. Al/i and Al/ω, indicate that the flow stress of both composites is strongly temperature dependent and exhibit distinct regimes with increasing temperature. Differences exist between the two composites, in particular in yield stress values. In the low temperature regime (T ≤ 570K), the yield stress of the Al/ω composite is nearly 75% higher than that of the Al/i composite, while for T > 570K both composites exhibit similar yield stress values. The results are interpreted in terms of load transfer contribution between the matrix and the reinforcement particles and elementary dislocation mechanisms in the Al matrix.

    This phenomenon was found specifically in the dispersion fuel plate with Si addition in the Al matrix to suppress interaction layer (IL) formation between UMo and Al. It is known that the stresses induced by fission induced swelling in U-Mo fuel particles are relieved by creep deformation of the IL, surrounding the fuel particles, that has a much higher creep rate than the Al matrix. Thus, when IL growth is suppressed, the stress is instead exerted on the Al matrix. The observed rupture in the Al matrix is believed to be caused when the stress exceeded the rupture strength of the Al matrix. In this study, the possibility of creep rupture of the Al matrix between the neighboring U-Mo fuel particles was examined using the ABAQUS finite element analysis (FEA) tool. The predicted rupture time for a plate was much shorter than its irradiation life indicating a rupture during the irradiation. The higher stress leads Al matrix to early creep rupture in this plate for which the Al matrix with lower creep strain rate does not effectively relieve the stress caused by the swelling of the U-Mo fuel particles. For the other plate, no rupture was predicted for the given irradiation condition. The effect of creeping of the continuous phase on the state of stress is significant.

    CdTe: AI films were grown by the close space vapor transport technique combined with free evaporation (CSVT-FE). The Aluminum (Al) evaporation was made by two kinds of sources: one made of graphite and the other of tantalum. The films were deposited on glass substrates. The Al source temperature was varied maintaining the CdTe source temperature fixed as well as the substrate temperature. The films were characterized by x-ray energy dispersive analysis (EDAX), x-ray diffraction and optical transmission. The results showed for the films grown with the graphite source for Al evaporation, the Al did not incorporate in the CdTe matrix, at least to the level of EDAX sensitivity; they maintained the same crystal structure and band gap. For the samples grown with the tantalum source, we were able to incorporate the Al. The x-ray diffraction patterns show that the films have a crystal structure that depends on Al concentration. They were cubic up to 2.16 at. % Al concentration; for 19.65 at. % we found a mixed phase; for Al concentration higher than 21 at. % the films were amorphous. For samples with cubic structure it was found that the lattice parameter decreases and the band gap increases with Al concentration. (Author)

    Amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy (SMA) are the most frequent motor neuron disorders in adulthood and infancy, respectively. There is a growing literature supporting common pathophysiological patterns between those disorders. One important clinical issue for that is the co-occurrence of both diseases within a family. To collect families in which ALS and SMA patients co-exist and describe the phenotype and the genotype of ALS patients. Nine families with co-occurrence of SMA and ALS have been gathered over the last 15 years. Epidemiological, phenotype and genetic status were collected. Out of the nine families, six corresponded to the criteria of familial ALS (FALS). Clinical data were available for 11 patients out of the 15 ALS cases. Mean age of onset was 58.5 years, site of onset was lower limbs in nine cases (81.8%), median duration was 22 months. Four ALS patients carried a mutation: three mutations in SOD1 gene (G147N in two cases and one with E121G) and one repeat expansion in the C9ORF72 gene. Three patients had abnormal SMN1 copy numbers. While the high proportion of familial history of ALS cases in these ALS-SMA pedigrees could have suggested that these familial clusters of the two most frequent MND rely on a genetic background, we failed to exclude that this occurred by chance.

    In GaN/(Al,Ga)N high-electron-mobility transistors (HEMT), AlN interlayer between GaN channel and AlGaN barrier suppresses alloy scattering and significantly improves the electron mobility of the two-dimensional electron gas. While high concentrations of gallium were previously observed in Al-polar AlN interlayers grown by metal-organic chemical vapor deposition, the N-polar AlN (Al x Ga1-x N) films examined by atom probe tomography in this study exhibited aluminum compositions (x) equal to or higher than 95% over a wide range of growth conditions. The also investigated AlN interlayer in a N-polar GaN/AlN/AlGaN/ S.I. GaN HEMT structure possessed a similarly high x content.

  8. 26Al in the interstellar medium

    Several different lines of physical reasoning have converged on the importance of the radioactive nucleus 26 Al. The sciences of meteoritics, nucleosynthesis, gamma-ray astronomy, galactic chemical evolution, solar system formation, and interstellar chemistry all place this nucleus in a central position with possible profound implications. Perhaps more importantly the study of this radioactivity can unite these diverse fields in a complicated framework which will benefit all of them. This review traces the evolution of ideas concerning 26 Al in the context of these disciplines. 26 Al was first discussed for the possibility that its decay energy could melt meteorite parent bodies, and its daughter, 26 Mg, was later found in meteorites with enhanced abundance. It was also among the first radioactivities expected to be synthesized in interestingly large quantities in nulceosynthetic events. The first definitive detection of gamma-rays from an interstellar radioactivity is that of 1.809 MeV gamma-rays from 26 Al. This discovery has many implications, some of which are outlined here. The whole problem of isotopic anomalies in meteorites is greatly influenced by the specific issues surrounding excess 26 Mg, whether it represents in situ decay of 26 Al or memory of conditions of the ISM. The relationships among these ideas and their implications are examined. (orig.)

    Full Text Available The moslem ethics of life is based on movement as ex­pressed in certain terms like al-sharī’ah, al-tarīqah, al-sirāt, al-sabīl and al-manhaj, that make sense of way and teachings to achieve good life. Islam obliges and gives appreciation of the achievements of Mus­lims. The Qur’an uses several terms to refer to such work; ‘charity, kasb, juhd, ibtighâ’, sa ’yu and su ’âl. From this concept, the Qur’an considers work as nob­le, while begging is despicable. Work means thankful to God for the potential He bestows. The Qur’an promotes work not only because it is the way to achieve the wealth, but also because it possesses the its sacred value for the benefit of fulfilling livelihood. Therefore the work should also be done based on ethical values .

    Full Text Available Fassen wir Geist und Natur nicht als Dichotomie sondern im Sinne von Peirce als Kontinuität auf, dann lässt die genauere Betrachtung des Körpers semiotische Leibphänomene als Zeichen einer Sprache erkennen, deren Grammatik es – im Sinne einer «Bioarchäologie» – zu entschlüsseln gilt. Hierfür stellen die Neurowissenschaften mit modernen Visualisierungstechniken geeignete epistemische Hilfsmittel bereit: Sie machen körperliche Vorgänge des Informationsaustausches sichtbar und heben die semiotisch wenig erschlossene Ebene komplexer neuronaler Zeichentransformationen ans Licht. Um eine Integration der physiologischen und psychologischen Perspektive bemüht sich das transdisziplinäre Projekt der «Neuropsychoanalyse». Sie hebt die Relevanz natürlicher Verarbeitungsmechanismen des Körpers für die subjektiv geprägten Zeichentransformationen des mentalen Erlebens hervor und weicht eine semiotisch allzu undurchlässige Grenzziehung zwischen Psycho- und Neurodynamik etwas auf. Die Hirntätigkeit als potenziell erkenntnisleitenden Zeichenprozess zu verstehen, darf aber nicht in einer unreflektierten Bezugnahme auf neuronale Zeichensysteme münden, wenn die Neuropsychoanalyse mehr als nur eine medienwirksame Neurokarikatur psychodynamischer Konzepte erreichen will.

    Threshold states in /sup 26/Al have been re-examined using the /sup 27/Al(/sup 3/He,..cap alpha..)/sup 26/Al and /sup 25/Mg(/sup 3/He,d..gamma..)/sup 26/Al reactions in order to resolve apparent ambiguities in some of the previously reported properties of these states. In particular, the s-wave resonance strength reported at E=37 keV is now found to be located at E/sub c.m./=57.54 keV, and the proton width for the 374 keV resonance has been revised to GAMMA/sub p/=0.82 eV. These results have been used to calculate a new resonance strength of ..omega gamma..= 1.6 x 10/sup -13/ eV for the 57.54 keV resonance. As a result, the stellar production rate for /sup 26/Al is increased by a factor approx.=3-38 for temperatures T/sub 9/=0.05-0.1.

    Highlights: • The optimal welding condition is achieved at 100 J and 0.1 s. • Failure load first increases and then decreases with increasing welding energy. • The highest failure load after welding is close to that of the clad sheets. • At low energy levels failure occurs in the mode of interfacial failure. • At high energy levels failure takes place at the edge of nugget region. - Abstract: Solid-state ultrasonic spot welding (USW) was used to join Al/Mg/Al tri-layered clad sheets, aiming at exploring weldability and identifying failure mode in relation to the welding energy. It was observed that the application of a low welding energy of 100 J was able to achieve the optimal welding condition during USW at a very short welding time of 0.1 s for the tri-layered clad sheets. The optimal lap shear failure load obtained was equivalent to that of the as-received Al/Mg/Al tri-layered clad sheets. With increasing welding energy, the lap shear failure load initially increased and then decreased after reaching a maximum value. At a welding energy of 25 J, failure occurred in the mode of interfacial failure along the center Al/Al weld interface due to insufficient bonding. At a welding energy of 50 J, 75 J and 100 J, failure was also characterized by the interfacial failure mode, but it occurred along the Al/Mg clad interface rather than the center Al/Al weld interface, suggesting stronger bonding of the Al/Al weld interface than that of the Al/Mg clad interface. The overall weld strength of the Al/Mg/Al tri-layered clad sheets was thus governed by the Al/Mg clad interface strength. At a welding energy of 125 J and 150 J, thinning of weld nugget and extensive deformation at the edge of welding tip caused failure at the edge of nugget region, leading to a lower lap shear failure load

    The Al 2p and Br 3d inner-shell photoelectron spectra of aluminum tribromide monomer and dimer vapor were measured at 90 and 95 eV photon energy, respectively, to determine the core electron binding energies of the atoms in the two molecular species. While AlBr 3 has three identical Br atoms, Al 2 Br 6 exhibits four terminal and two bridging Br atoms. The species are identified by their distinct valence photoelectron spectra. Comparison of the observed Al 2p 1/2 and Al 2p 3/2 electron binding energies of AlBr 3 with those of Al 2 Br 6 shows that there is a chemical shift of (0.15 ± 0.03) eV to lower energy in the dimer. In Al 2 Br 6 , an assignment is proposed in which the Br 3d 3/2 and Br 3d 5/2 binding energies of terminal Br atoms are (1.18 ± 0.03) eV lower than those of bridging Br atoms. This assignment assumes that both types of Br atoms have similar cross-sections for ionization. With this result, the Br 3d 3/2 and Br 3d 5/2 binding energies of Br atoms in AlBr 3 are (0.81 ± 0.03) eV lower than those of bridging Br atoms of the dimer but (0.37 ± 0.03) eV higher than those of terminal Br atoms of the dimer. The obtained chemical shifts are considered in terms of the binding relations and electron density distributions in both molecules. Chemical shifts that are larger than a few hundred millielectron volts, as observed in the Al 2 Br 6 /AlBr 3 system, offer potential to study the dissociation dynamics of the dimer in a femtosecond visible or ultraviolet-pump/XUV-probe experiment

    1992-01-01

    This paper reports on partitioning during rapid solidification of dilute Al-Ge alloys. Implanted thin films of Al have been pulsed-laser melted to obtain solidification at velocities in the range of 0.01 ms to 3.3 m/s, as measured by the transient conductance technique. Previous and subsequent Rutherford Backscattering depth profiling of the Ge solute in the Al alloys has been used to determine the nonequilibrium partition coefficient k. A significant degree of lateral film growth during solidification confines determination of k to the placing of an upper bound of 0.22 on k for solidification velocities in this range. The authors place a lower limit of 10 m/s on the diffusive velocity, which locates the transition from solute partitioning to solute trapping in the Continuous Growth Model

    2015-01-01

    This paper intends to investigate the axiomatic foundations of algebra, as they were presented in the book of algebra of al-Khwarizmi (9 th century), and as they were developed in many subsequent Arabic works. The paper gives also a description of algebra evolution towards a discipline independent ofgeometry and arithmetic: the two disciplines whosemarriage had led to its birth.By an in depth reading of some details in the text of al Khwarizmi , we concluded that this mathematician intended to lay down the axiomatic foundations of that new discipline. His resort to arithmetical and geometrical means was a way of making his theory more accessible. He used them to justify the axioms: those that were not explicitly introduced per se, and those that were remained implicit. The paper also relies on some unedited writingsof al-Khwarizmi's successors, which could shedlight on the ways they used to consolidate the foundations of algebra and improve its methods. (author)

    While the ALS has turned out to be a world-leader in providing beams of soft X-rays -- indeed, furnishing these beams remains its core mission -- there has nonetheless been a steadily growing demand from synchrotron radiation users for harder X-rays with higher photon energies. The clamor has been strongest from protein crystallographers whose seemingly insatiable appetite for solving structures of biological macromolecules could not be satisfied by the number of crystallography beamlines available worldwide. But how to provide these X-rays in a cost-effective way without disrupting the thriving research programs of the existing ALS users was the problem. Superconducting bend magnets (superbends) provided the answer for the ALS, which adopted a proposal to replace some of the normal combined-function (gradient) magnets in the curved arcs of the storage ring with superconducting dipoles that could generate higher magnetic fields and thus synchrotron light with a higher critical energy

    AlTiC master alloys are a new grain refiner type to produce an equiaxed grain structure of cast extrusion and rolling ingots. These master alloys contain Ti carbides which act as nucleants of the {alpha} solid solution during solidification. The TiC content is lower than the TiB{sub 2} content of the industrial proved AlTiB master alloys. Benefits of the AlTiC master alloys are the low agglomeration tendency of the Ti carbides in the melt and that no Zr poisoning takes place. Despite of the low Ti carbide content the grain refinement performance can be very efficient, if low melt temperatures during casting will be used and as result of this a sufficient constitutional supercooling at the solidification front is achieved.

    2012-01-01

    Full Text Available AL amyloidosis is caused by clonal plasma cells that produce immunoglobulin light chains which misfold and get deposited as amyloid fibrils. Therapy directed against the plasma cell clone leads to clinical benefit. Melphalan and corticosteroids have been the mainstay of treatment for a number of years and the recent availability of other effective agents (IMiDs and proteasome inhibitors has increased treatment options. Autologous stem cell transplant (ASCT has been used in the treatment of AL amyloidosis for many years. It is associated with high rates of hematologic response and improvement in organ function. However, transplant carries considerable risks. Careful patient selection is important to minimize transplant related morbidity and mortality and ensure optimal patient outcomes. As newer more affective therapies become available the role and timing of ASCT in the overall treatment strategy of AL amyloidosis will need to be continually reassessed.

He made a chronological overview of calendars from many nations, including Persians, Greeks, Egyptians, Jews, Melkitian and Nestorian Christians, Sabeyaans as well as the old Arabs. Data presented in the work, according to the later authors, were taken from very reliable sources. He was contemporary of Ibn-Sina, and thanks to their friendship, they have discussed very much miscellaneous topics. He belonged to the group of scholars, taken by Gaznevian Soultan Mahmud to a long journey to India. Afterwards Al-Biruni wrote and published detailed work "Description of India"--a work on cultural history of India. Due to excellent abilities of Al-Biruni as a philosopher and scholar, there are still significant and reliable notes about buddhistic philosophy, structure of castes and Brahmans' life style. In this Al-Biruni's masterpiece, there are many comparative analysis of Suffism and certain Indian philosophical methods. Al-Biruni's most important work is "Pharmacopoeia"--"Kitab al-saydala", which brilliantly describes all medicaments. This work has been published in many languages. He also wrote few works on astronomy and astrology. In those works he has explained some astrological events through scientific approach in a such peculiar way that nobody has ever explained before. He was also interested in sciences like geology, mineralology, geography, mathematics, psychology and many others.

  3. Instability of TiC and TiAl3 compounds in Al-10Mg and Al-5Cu alloys by addition of Al-Ti-C master alloy

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The performance of Al-Ti-C master alloy in refining Al-10Mg and A1-5Cu alloys was studied by using electron probe micro-analyzer (EPMA) and X-ray diffractometer (XRD) analysis.The results indicate that there are obvious fading phenomena in both Al-10Mg and Al-5Cu alloys with the addition of Al-5Ti-0.4C refiner which contains TiC and TiAl3 compounds.Mg element has no influence on the stability of TiC and TiAl3, while TiC particles in Al-10Mg alloy react with Al to form Al4C3 particles, resulting in the refinement fading.However, TiC particles are relatively stable in Al-5Cu alloy, while TiAl3 phase reacts with Al2Cu to produce a new phase Ti(Al, Cu)2, which is responsible for the refinement fading in Al-5Cu alloy.These indicate that the refinement fading will not occur only when both the TiC particles and TiAl3 compound of Al-Ti-C refiner are stable in Al alloys.

    The magnetic properties of NdAl2 are calculated using a Hamiltonian including crystal-field and isotropic exchange interaction terms. A two-dimensional mean-field theory is evaluated to calculate single-crystal magnetization curves. It is shown that the magnetic properties can be understood using...... the crystal-field parameters derived from the magnetic exciton spectrum measured by Houmann et al. by means of inelastic neutron scattering. The combined lambda -Schottky anomaly in the heat capacity is explained. No additional parameters are introduced....

    Synopsis Given the severity of their illness and lack of effective disease modifying agents, it is not surprising that most patients with ALS consider trying complementary and alternative therapies. Some of the most commonly considered alternative therapies include special diets, nutritional supplements, cannabis, acupuncture, chelation and energy healing. This chapter reviews these in detail. We also describe 3 models by which physicians may frame discussions about alternative therapies: paternalism, autonomy and shared decision making. Finally, we review a program called ALSUntangled which using shared shared decision making to review alternative therapies for ALS. PMID:26515629

    We were successful in growing a uniform flat Al 2 O 3 film on the Cu-9%Al(111) surface using the improved cleaning process, low ion energy and short time sputtering. The growth of ultra-thin film of Al 2 O 3 on Cu-9%Al was investigated using Auger electron spectroscopy (AES) and a scanning electron microscope (SEM). The Al 2 O 3 film whose maximum thickness was about 4.0 nm grew uniformly on the Cu-9%Al surface. The Al and O KLL Auger peaks of Al 2 O 3 film shifted toward low kinetic energy, and the shifts were related to Schottky barrier formation and band bending at the Al 2 O 3 /Cu-9%Al interface. The thickness of Al 2 O 3 film on the Cu-9%Al surface was controlled by the oxygen exposure

    The mechanism of the synthetic formation of β-Mg 2 Al 3 and γ-Mg 17 Al 12 has been studied. Mechanical alloying of Mg and Al powders with the atomic ratio of Mg:Al = 2:3 in toluene solution yields β-Mg 2 Al 3 compound after milling for 30 h. The γ-Mg 17 Al 12 can be formed by heating the β-Mg 2 Al 3 at 430°C under high vacuum. The measured hydrogen capacities of β-Mg 2 Al 3 and γ-Mg 17 Al 12 as hydride at 300°C are 3.2 and 4.9 wt%, respectively. Microstructure of the Mg-Al specimen shows that on hydriding at 300°C the polygonal shape of the γ-Mg 17 Al 12 changes into irregular shapes which are composed of γ-MgH 2 and Al. (author)

    Changes in the structure, hardness, mechanical properties, and friction coefficient of Al-30% Sn, Al-15% Sn-25% Pb, and Al-5% Sn-35% Pb (wt %) alloys subjected to severe plastic deformation by equal-channel angular pressing (with a force of 40 tonne) and by shear at a pressure of 5 GPa have been studied. The transition into the nanocrystalline state was shown to occur at different degrees of plastic deformation. The hardness exhibits nonmonotonic variations, namely, first it increases and subsequently decreases. The friction coefficient of the Al-30% Sn, Al-15% Sn-25% Pb, and Al-5% Sn-35% Pb alloys quenched from the melt was found to be 0.33; the friction coefficients of these alloys in the submicrocrystalline state (after equal-channel angular pressing) equal 0.24, 0.32, and 0.35, respectively. The effect of disintegration into nano-sized powders was found to occur in the Al-15% Sn-25% Pb, and Al-5% Sn-35% Pb alloys after severe plastic deformation to ɛ = 6.4 and subsequent short-time holding.

    Full Text Available Ball milling and spark plasma sintering were successfully used to produce carbon nanotube reinforced Al6061 and Al2124 nanocomposites which have potential applications in the fields of aerospace, automotive, electronics, and high precision instrumentation. Al2124 and Al6061 nanocomposite powders containing 0.5 to 2 wt.% CNTs prepared through sonication and wet ball milling were spark plasma sintered at 400, 450, and 500°C for 20 minutes under a pressure of 35 MPa. CNTs were better dispersed, and less agglomerated and had good adhesion to the matrix in composites containing 1 wt.% CNTs. The increase of CNT content to 2 wt.% led to the formation of CNT clusters which resulted in less uniform and homogenous composite powders. Almost full densification of Al6061 reinforced with CNTs was achieved at 500°C. Also, CNTs reinforced Al2124 nanocomposites reached very high densities at 500°C. Composites reinforced with 1 wt.% CNTs displayed better densification compared to composites containing 2 wt.% CNTs. The increase of CNTs content from 0.5 to 1 wt.% increased the hardness of the Al6061 and Al2124 alloys to maximum values. Further increase of CNTs content to 2 wt.% decreased the hardness to values lower than that of the monolithic alloys.

    In the present study, mechanical properties and deformation behavior of Al/Al7075, two-phase material were investigated. The two-phase materials were fabricated by mixing commercially pure Al powder with Al7075 chips and consolidating the mixture through hot extrusion process at 500 o C. Mechanical properties and deformation behavior of the fabricated samples were evaluated using tensile and compression tests. A scanning electron microscope was used to study the fracture surface of the samples including different amount of Al powder, after they were fractured in tensile test. The results of the tensile and compression tests showed that with decreasing the amount of Al powder, the strength increases and ductility decreases. Calculation of work hardening exponent (n) indicated that deformation behavior does not follow a regular trend. In a way that the n value was approved to be variable and a strong function of strain and Al powder wt% of the sample. The results of the fractography studies indicate that the type of fracture happened changes from completely ductile to nearly brittle by decreasing the wt% of Al powder from 90% to 40%.

    Genetic variants are implicated in the development of amyotrophic lateral sclerosis (ALS), but it is unclear whether the burden of rare variants in ALS genes has an effect on survival. We performed whole genome sequencing on 8 familial ALS (FALS) patients with superoxide dismutase 1 (SOD1) mutation and whole exome sequencing on 46 sporadic ALS (SALS) patients living in Hong Kong and found that 67% had at least 1 rare variant in the exons of 40 ALS genes; 22% had 2 or more. Patients with 2 or more rare variants had lower probability of survival than patients with 0 or 1 variant (p = 0.001). After adjusting for other factors, each additional rare variant increased the risk of respiratory failure or death by 60% (p = 0.0098). The presence of the rare variant was associated with the risk of ALS (Odds ratio 1.91, 95% confidence interval 1.03-3.61, p = 0.03), and ALS patients had higher rare variant burden than controls (MB, p = 0.004). Our findings support an oligogenic basis with the burden of rare variants affecting the development and survival of ALS. Copyright © 2017 The Author(s). Published by Elsevier Inc.

    1988-01-01

    As a first step towards understanding the reduced embrittlement of L1 0 Ti-Al alloys which accompanies the introduction of small concentrations of V, we have determined from first principles, using full-potential linearized--augmented-plane-wave calculations, the equilibrium values of the structural parameters and the associated electronic structure for the stoichiometric (L1 0 ) Ti-Al (tetragonal) compound. Our calculated values of c/a and a are in good agreement with experiment. Using the same method of calculation, we have also studied the electronic structure associated with the (hypothetical) L1 0 V-Al alloy that would form when V is substituted for Ti. We find that (1) the electronic structures of these V-Al alloys are relatively insensitive to variations of c/a and a; (2) near the Ti-Al equilibrium geometry, the electronic structures of the V-Al and Ti-Al alloys are very similar; and (3) that a rigid-band model involving substitution of V for Ti can be used to gain a qualitative understanding of the reduction in c/a which accompanies the introduction of small concentrations of V. We relate the reduction in c/a to important changes in the bonding that accompany the occupation of bands immediately above the Fermi level of the stoichiometric Ti-Al compound

    We evaluated the genetic impact of the amyotrophic lateral sclerosis (ALS) risk gene never in mitosis gene a-related kinase 1 (NEK1) in a Belgian cohort of 278 patients with ALS (n = 245) or ALS with frontotemporal dementia (ALS-FTD, n = 33) and 609 control individuals. We identified 2 ALS patients carrying a loss-of-function (LOF) mutation, p.Leu854Tyrfs*2 and p.Tyr871Valfs*17, that was absent in the control group. A third LOF variant p.Ser1036* was present in 2 sibs with familial ALS but also in an unrelated control person. Missense variants were common in both patients (3.6%) and controls (3.0%). The missense variant, p.Arg261His, which was previously associated with ALS risk, was detected with a minor allele frequency of 0.90% in patients compared to 0.33% in controls. Taken together, NEK1 LOF variants accounted for 1.1% of patients, although interpretation of pathogenicity and penetrance is complicated by the observation of occasional LOF variants in unaffected individuals (0.16%). Furthermore, enrichment of additional ALS gene mutations was observed in NEK1 carriers, suggestive of a "second hit" model were NEK1 variants may modify disease presentation of driving mutations.

    Williams (1981) and Williams and Rich (1991) attributed Australian Quaternary fossil eggshell that differed from that of emu Dromaius novaehollandiae to the extinct bird Genyornis newtoni without any osteological or embryonic support. Such association by proximity or abundance mirrors the case of the mistaken association of oviraptor eggs to Protoceratops in the 1920's by Andrews (Grellet-Tinner and Makovicky, 2006). No other candidate species was considered, and this attribution has been unchallenged and followed by everyone thereafter. Much research has been done on this Australian eggshell, with one result being that the extinction of the parent of this eggshell is the most well documented for a taxon in Australia (e.g., Miller et al., 1999, 2005). Grellet-Tinner et al. (2016) raised several problems with the identity of the eggshell Williams (1981) attributed to Genyornis newtoni and suggested that extinct megapodes of the genus Progura were the more likely layer of this eggshell type, therein referred to as ;putative Genyornis oological material; (PGOM). Miller et al. (2017) challenged our hypothesis stating that ;Based on the dimensions of the reconstructed Spooner Egg,Grellet-Tinner et al. (2016)argue that PGOM is too small for a bird with the body mass estimated for Genyornis (168-275 kg) … …[and] …. None of the additional PGOM observations reported byGrellet-Tinner et al. (2016)are inconsistent with a Genyornis parent;. Here we take the opportunity to respond to their critique, the basis of which resolves into a few points, which we address in turn.

    1999-01-01

    The systematic studies of dissipative processes in light systems were completed with experiments dedicated to the measurement of the excitation functions in 19 F + 27 Al and 27 Al + 27 Al systems in order to obtain deeper insight on DNS configuration and its time evolution. The excitation function for 19 F + 27 Al system evidenced fluctuations larger than the statistical errors. Large Z and angular cross correlation coefficients supported their non-statistical nature. The energy dependence of second order observables, namely the second moment of the charge distribution and the product ω·τ (ω - the angular velocity of the DNS and τ its mean lifetime) extracted from the angular distributions were studied for 19 F + 27 Al case. In this contribution we are reporting the preliminary results of similar studies performed for 27 Al + 27 Al case. The variance of the charge distribution were obtained fitting the experimental charge distribution with a Gaussian centered on Z = 13 and the product ω·τ was extracted from the angular distributions. The results for 19 F + 27 Al case are confirmed by a preliminary analysis of the data for 27 Al + 27 Al system. The charge variance and ω·τ excitation functions for Z = 11 fragment are represented together with the excitation function of the cross section. One has to mention that the data for 27 Al + 27 Al system were not corrected for particle evaporation processes. The effect of the evaporation corrections on the excitation function was studied using a Monte Carlo simulation. The α particle evaporation was also included and the evaluation of the particle separation energies was made using experimental masses of the fragments. The excitation functions for 27 Al + 27 Al system for primary and secondary fragments were simulated. No structure due to particle evaporation was observed. The correlated fluctuations in σ Z and ω·τ excitation functions support a stochastic exchange of nucleons as the main mechanism for

    Cross sections for the 26 Mg(p,n) 26 Al reaction were measured from threshold at 4.988 MeV to 5.820 MeV. Cross sections for the 23 Na(α,n) 26 Al reaction were measured from threshold at 3.483 MeV to 4.597 MeV. In each case, separate measurements were to the ground state and to the first and second excited states of 26 Al. Cross sections for the inverse reactions were calculated and reaction rate factors relating to the destruction of 26 Al in a supernova environment were determined. Astrophysical implications relating to the observation of live and extinct 26 Al are discussed. Excitation functions for several additional exit channels for the 26 Mg + rho and 23 Na + α reactions are reported

    This paper aims to bring some clarification on grain refinement and modification of high strength alloys used in aerospace technique. In this work it was taken into account 7075 Al alloy, and the melt treatment was carried out by placing in the form of master alloy wire ternary AlTiB the casting trough at 730°C. The morphology of the resulting microstructures was characterized by optical microscopy. Micrographs unfinished and finished with pre-alloy containing ternary Al5Ti1B evidence fine crystals, crystal containing no columnar structure and highlights the size of the dendrites, and intermetallic phases occurring at grain boundaries in Al-Zn-Mg-Cu alloy. It has been found that these intermetallic compounds are MgZn2 type. AlTiB master alloys finishing ensures a fine eutectic structure, which determines the properties of hardware and improving the mechanical properties of aluminum alloys used in aeronautical engineering.

    Adherence of protective oxides on NiCrAl and CoCrAl superalloys has been promoted by a dispersion of a highly oxygen reactive element or its oxide being produced within the protection system. Two aspects of this subject are investigated here: the use of Al 2 O 3 as both the dispersion and protective oxide; and the production of an HfO 2 dispersion while simultaneously aluminizing the alloy. It was found that an Al 2 O 3 dispersion will act to promote the adherence of an external scale of Al 2 O 3 to a degree comparable to previously tested dispersions and an HfO 2 dispersion comparable to that produced by a Rhines pack treatment is produced during aluminization

    Neutron diffraction experiments on the Al 3 Ce and Al 11 Ce 3 compounds have been performed on the multidetector of the I.L.L. high flux reactor. No magnetic structure has been detected on the Al 3 Ce compound down to 20 mK. This confirms the non magnetic ground state of Al 3 Ce. For Al 11 Ce 3 , two magnetic structures have been observed: a ferromagnetic one at 4.2 K and an antiferromagnetic one at 2 K. The antiferromagnetic structure, which corresponds to a propagation vector (0,0,1/3), implies a strong reduction of the magnetic moment of determined sites; this reflects the Kondo character of the compounds

    Research highlights: → In this study, Fe 3 Al has been chosen as cladding powder due to its excellent properties of wear resistance and high strength, etc. → Laser cladding of Fe 3 Al + TiB 2 /Al 2 O 3 pre-placed alloy powder on Ti-6Al-4V alloy substrate can form the Ti 3 Al/Fe 3 Al + TiB 2 /Al 2 O 3 ceramic layer, which can increase wear resistance of substrate. → In cladding process, Al 2 O 3 can react with TiB 2 leading to formation of Ti 3 Al and B. → This principle can be used to improve the Fe 3 Al + TiB 2 laser-cladded coating. - Abstract: Laser cladding of the Fe 3 Al + TiB 2 /Al 2 O 3 pre-placed alloy powder on Ti-6Al-4V alloy can form the Ti 3 Al/Fe 3 Al + TiB 2 /Al 2 O 3 ceramic layer, which can greatly increase wear resistance of titanium alloy. In this study, the Ti 3 Al/Fe 3 Al + TiB 2 /Al 2 O 3 ceramic layer has been researched by means of electron probe, X-ray diffraction, scanning electron microscope and micro-analyzer. In cladding process, Al 2 O 3 can react with TiB 2 leading to formation of amount of Ti 3 Al and B. This principle can be used to improve the Fe 3 Al + TiB 2 laser cladded coating, it was found that with addition of Al 2 O 3 , the microstructure performance and micro-hardness of the coating was obviously improved due to the action of the Al-Ti-B system and hard phases.

    The Al=Al double bond is elusive in chemistry. Herein we report the results obtained via combined photoelectron spectroscopy and ab initio studies of the LiAl 2 H 4 - cluster that confirm the formation of a conventional Al=Al double bond. Comprehensive searches for the most stable structures of the LiAl 2 H 4 - cluster have shown that the global minimum isomer I possesses a geometric structure which resembles that of Si 2 H 4 , demonstrating a successful example of the transmutation of Al atoms into Si atoms by electron donation. Theoretical simulations of the photoelectron spectrum discovered the coexistence of two isomers in the ion beam, including the one with the Al=Al double bond. © 2017 Wiley-VCH Verlag GmbH & Co.

    In this work we have utilized computer simulation techniques to study microstructural defects, such as point defects and interfaces, in the Al-Mo alloy. Such alloy is taken as a model to study the Al(fcc)/U-Mo(bcc) interface. The EAM interatomic potential used has been fitted to the formation energy and lattice constant of the AlMo 3 intermetallic. Formation of vacancies for both components Al and Mo and anti-sites, Al Mo and Mo Al , as well as vacancy migration was studied in this structure. We found that the lowest energy defect complex that preserves stoichiometry is the antisite pair Al Mo +Mo Al , in correspondence with other intermetallics of the same structure. Our results also suggest that the structure of the Al(fcc)/Mo(bcc) interface is unstable, while that of the Al(fcc)/Al 5 Mo interface is stable, as observed experimentally. (author) [es

    The constitution of alloys and the liquidus surface in the Al-rich corner of the Al-Si-Sm ternary system were determined by the examination of controlled heated and cooled specimens, as well as heat-treated specimens by means of optical and scanning electron microscopy, energy-dispersive X-ray spectroscopy, differential thermal analysis and X-ray diffraction. The Al-rich corner of the Al-Si-Sm ternary system comprises five regions of primary crystallisation (α Al , β Si , Al 3 Sm, Al 2 Si 2 Sm and AlSiSm) with following characteristic invariant reaction sequences: ternary eutectic reaction L → α Al + β Si + Al 2 Si 2 Sm, and two liquidus transition reactions, i. e., L + Al 3 Sm → α Al + AlSiSm, and L + AlSiSm → α Al + Al 2 Si 2 Sm. Along with the position of ternary eutectic and both interstitial points in the Al-rich corner of the Al-Si-Sm ternary system, the temperatures for each reaction were determined. (orig.)

  18. Electronic Structures and Bonding Properties of Ti2AlC and Ti3AlC2

    The relation among electronic structure, chemical bond and property of Ti2AlC, Ti3AlC2 and doping Si into Ti2AlC was studied by density function and the discrete variation (DFT-DVM) method. After adding Si into Ti2AlC, the interaction between Si and Ti is weaker than that between Al and Ti, and the strengths of ionic and covalent bonds decrease both. The ionic and covalent bonds in Ti3AlC2, especially in Ti-Al, are stronger than those in Ti2AlC. Therefore, in synthesis of Ti2AlC, the addition of Si enhances the Ti3AlC2 content instead of Ti2AlC. The density of state (DOS) shows that there is mixed conductor characteristic in Ti2AlC and Ti3AlC2. The DOS of Ti3AlC2 is much like that of Ti2AlC. Ti2SixAl1-x C has more obvious tendency to form a semiconductor than Ti2AlC, which is seen from the obvious difference of partial DOS between Si and Al3p.

    We present the results of 27 Al nuclear magnetic resonance (NMR) experiments on the phase Co 4 Al 13 . These results are compared to a recent structure model [1], which demonstrates a unique bonding for Al atoms in the Co-Al-Co molecular groups. In our measurement, two 27 Al signals were identified. The first one originates from Al atoms forming cages. The second signal corresponds to Al sites with exceptionally large almost axially symmetric quadrupole coupling. This finding is in perfect agreement with isolated Co-Al-Co molecular groups in accordance to Ref. [1].
