    Full Text Available Este artículo presenta los resultados de un estudio sobre los posteos publicados por los candidatos al Concejo Deliberante de la Ciudad de Rosario, Argentina, en los muros de sus páginas oficiales en Facebook, durante la campaña electoral local de 2015. Con un diseño exploratorio, se estudiaron las publicaciones de diez candidatos pertenecientes a las diferentes listas, durante 25 días. Para la recopilación del corpus se utilizaron herramientas digitales combinadas con una observación directa y herramientas estadísticas para el procesamiento de los datos. Entre los hallazgos se destacan: el escaso lugar que los políticos otorgan a la polémica con postulantes opositores, el hecho de que los usuarios interactúen con la página oficial de un solo candidato, la baja reiteración en la actividad de comentar de cada usuario y la exigua presencia de respuestas por parte de los candidatos.

    Full Text Available El presente artículo analiza los principios que se encuentran plasmados a nivel internacional, específicamente en el Estatuto de Roma de 1998 para el establecimiento de la Corte Penal Internacional, y el significado relevante que tienen con respecto a postulados, como el principio de legalidad en materia penal en Colombia. En este sentido, podemos observar importantes diferencias y consecuencias frente a aspectos como la competencia del derecho interno, y la noción de conducta penal descrita en nuestra legislación.

  3. Una aproximación al régimen del arbitraje nacional del nuevo estatuto del arbitraje en Colombia, Ley 1563 de 2012

    Directory of Open Access Journals (Sweden)

    Marcela Rodríguez Mejía

    2012-12-01

    Full Text Available El nuevo estatuto del arbitraje colombiano, esto es, la Ley 1563 del 12 de julio de 2012, “por medio de la cual se expide el Estatuto de Arbitraje Nacional e Internacional y se dictan otras disposiciones”, contempla un régimen arbitral dualista: mientras para el arbitraje de carácter internacional sigue lo dispuesto por la Ley Modelo de la Comisión de Naciones Unidas para el Derecho Mercantil Internacional de 1985, enmendada en 2003, para el arbitraje interno se aleja de lo allí propuesto y plantea un régimen diferente. El interrogante que en este artículo se pretende resolver es el de si el arbitraje interno que se configura en el Estatuto es un verdadero arbitraje o, por el contrario, resulta ser semejante al proceso judicial. Con ese objetivo se analiza la regulación que hace el estatuto de los aspectos más conducentes para la resolución de la pregunta.

    Full Text Available Entender la compraventa como el más usual y común de los contratos equivale a afirmar que éste es el elemento que permite la mayoría de las transacciones que se hacen entre particulares, comerciantes y empresarios, y que, por lo tanto, se hace necesaria una protección especial para los derechos de los compradores; protección que tiene que ver con el saneamiento por vicios ocultos consagrado desde el Código Civil, pasando por la presunción de garantía de funcionamiento, consagrada en el Código de Comercio, y llegando a su máximo desarrollo en las normas de protección al consumidor.

A decision with such production and marketing joined those aimed at improving the rural working class, so far neglected area. The application of the Statute of the Rural Pawn (1947 in a territory of frontier production and labor as the Chaco, in a local context unfavorable woke one of the most turbulent clashes between the agricultural cooperatives-organizations on behalf of its partners, and the Administration responsible for local implementation.

A esas decisiones de carácter productivo y de comercialización se sumaron aquellas orientadas a la mejora de la clase trabajadora rural, sector descuidado hasta el momento. La aplicación del Estatuto del Peón Rural (1947 en un territorio de frontera productiva y ocupacional como el Chaco, en un contexto local desfavorable, despertó uno de los más agitados enfrentamientos entre las entidades Cooperativas agrícolas-en representación de sus asociados- y la Administración local encargada de su aplicación.

Se pretende mantener la seguridad jurídica, como garantía del ejercicio del poder, institucionalizado en el estado y como garantía del ejercicio efectivo de los derechos humanos, que legitima la oposición, a regimenes totalitarios y cuestiona la soberanía estatal.

Para ello, se planteará una serie de recursos que buscan desbloquear al estudiante en un ambiente distendido, sobre todo los días previos al examen. La propuesta se centrará en la Prueba de Expresión e Interacción Orales, concretamente en la tarea 3 del nivel B1 y en la tarea 2 del nivel B2, que corresponden a la descripción de una fotografía. Se empleará, por una parte, un vídeo de carácter estático (donde el interlocutor no expresa movimientos corporales pronunciados y por otra, cómics de Argentina que a su vez servirán para ampliar el léxico en la variante rioplatense. Por último, se tratará el uso del rap como herramienta para mejorar la pronunciación, entonación y el empleo del lenguaje no verbal. Palabras claves: DELE, vídeo, cómic, rap.   Abstract: The purpose of the following essay is to train and to strengthen the skills and the competences required to pass the “Spanish as a Foreign Language Certificate”. In order to do so, we will first consider various resources which aim to release students from any kind of stress by setting up a relaxed atmosphere – especially a few days before the exam. The focus of the present essay has to be linked to the Expression and Oral Interaction tests and above all to the assignments 3 (B1 level and 2 (B2 level, and their picture descriptions. On the one hand, we will use a static video and, on the other hand, we will tackle Argentinian comics in order to expand students’ knowledge of the Río de la Plata lexicon. Finally, we will deal with the use of rap as a tool to improve pronunciation, intonation, and non-verbal communication. Key words: DELE, video, comic, rap.

Para ello se estudiará la compatibilidad que aguarda con el régimen especial del sistema de seguridad social en salud, tomando como punto de referencia la premisa impuesta por el mismo Estatuto que apunta a la subsidiariedad de su aplicación ante la prevalencia del régimen especial existente. Las implicaciones que directa o indirectamente pudiera tener el Estatuto sobre la materia, se estudiarán a la luz de diferentes normas que atañen al sector salud desde diferentes niveles de complejidad, abarcando el análisis de disposiciones ordinarias y de normas de rango constitucional.

    Rafael Amorim Martins de Sá

    2017-03-01

    Full Text Available Resumo No dia 12 janeiro de 2015, entrou em vigor o Estatuto da Metrópole, Lei nº 13.089, que estabelece diretrizes gerais para o planejamento, a gestão e a execução das funções públicas de interesse comum em regiões metropolitanas e em aglomerações urbanas, além de instituir normas sobre o Plano de Desenvolvimento Urbano Integrado e outros instrumentos de governança interfederativa. O presente artigo analisa essa norma jurídica, em especial os aspectos da governança interfederativa, traçando seu conceito, características, princípios e diretrizes. Para tanto, utilizou-se o método exploratório ou descritivo/causal, com revisão bibliográfica prévia. Entende-se que é de suma importância que governantes se ajustem às novas formas de se governar, sobrepondo o interesse comum ao individual, o que, em se tratando de desenvolvimento regional, se traduz na governança interfederativa. É claro que não se olvida da necessidade de outras normas jurídicas que cooperem com o Estatuto da Metrópole e o Estatuto da Cidade, porém resta perquirir e incentivar práticas de governanças que estejam preocupadas com a coletividade de determinada região e, mais ainda, do país.

    Jorge F. Aguirre Sala

    2017-01-01

    Full Text Available Las ciencias de la seguridad fragmentan al objeto de estudio al abordarlo desde múltiples ámbitos. Pero el propósito final es el mismo: Tomar decisiones en beneficio de la seguridad. El objetivo de este ensayo es mostrar el estatuto transdisciplinario de las Ciencias de la Seguridad; distinguirlo del interdisciplinario y multidisciplinario por la característica específica de la toma de decisiones. Y finalmente, concebir la toma de decisiones en el esquema de dilemas por la ausencia de protocolos. Para ello se aplica la metodología del análisis crítico conceptual de las nociones que se establecen y/o construyen en la literatura del tema. Por tanto, la metodología es cualitativa, de tipo Hermenéutico y del subtipo del interaccionismo simbólico. Los resultados muestran la transdisciplinariedad como un estatuto epistemológico en el cual se conoce para actuar y, en caso de las ciencias de la seguridad se actúa bajo la rectoría de principios y valores éticos.

    Bayuelo, Ezequiel

    Este estudio examino y comparo las actitudes de los candidatos a maestros de ciencias y los maestros de ciencias en servicio acerca de la utilizacion de las herramientas computadorizadas en las clases de ciencias. Tambien identifico y diferencio el uso que ellos dan a estas herramientas en las clases de ciencias. Este estudio presenta un diseno descriptivo exploratorio. Constituyeron la muestra trescientos diez sujetos que fueron candidatos a maestros de ciencias o maestros de ciencias en servicio. Para recoger los datos se construyo y valido un cuestionario de treinta y un itemes. Se utilizaron las pruebas estadisticas no parametricas Kruskal Wallis y Chi-cuadrado (test de homogeneidad) para establecer las diferencias entre las actitudes de los sujetos con relacion al uso de las herramientas computadorizadas en las clases de ciencias. Los hallazgos evidenciaron que son positivas y muy parecidas las actitudes de los candidatos a maestros y maestros en servicio hacia el uso de las herramientas computadorizadas. No hubo diferencias entre los candidatos y maestros en servicio en terminos de las actitudes de confianza y empatia hacia el uso de las herramientas computadorizadas en las clases de ciencias. En aspectos como el uso del banco de datos bibliografico Eric y el uso de las herramientas computadorizadas en actividades educativas como explorar conceptos, conceptuar, aplicar lo aprendido y hacer asignaciones hubo diferencias estadisticamente significativas entre los candidatos y los maestros en servicio. Al comparar las frecuencias observadas con las esperadas hubo mas maestros en servicio y menos candidatos que indicaron usar el anterior banco de datos y las herramientas computadorizadas en las mencionadas actividades educativas.

    Directory of Open Access Journals (Sweden)

    Noelia Trinidad Núñez

    2016-03-01

    Full Text Available Este trabajo se ocupa de la función de la costumbre como fundamento de la punibilidad en el Estatuto de la Corte Penal Internacional (ECPI. En primer lugar, estudia su lugar en el sistema de fuentes del Estatuto. Luego, investiga específicamente si en el ECPI existe una prohibición de fundamentar la punibilidad en el derecho consuetudinario. Para ello, estudia el alcance del principio de legalidad en el sistema de la CPI y su relación con el derecho consuetudinario. A continuación, analiza si el ECPI admite el recurso al derecho consuetudinario como criterio de interpretación, incluso en perjuicio del imputado. Finalmente, se ocupa de la propuesta de fundamentar la punibilidad directamente en normas consuetudinarias cuando la CPI ejerce jurisdicción sobre crímenes cometidos en el territorio y por nacionales de Estados no parte. El trabajo concluye que aunque el ECPI reconoce a la costumbre una función más marginal que la que tuvo en las experiencias precedentes de derecho internacional penal, existen, sin embargo, ámbitos en los que esta fuente puede tener significado y ello incluso en relación con la fundamentación de la punibilidad.

    Full Text Available La Universidad de Salamanca está en el siglo XVI, en permanente estado de cambio. Desde principios del siglo, con los Reyes Católicos, hasta finales, bajo Felipe II, ese espíritu de renovación se hará patente de un modo continuo. Del interés de Isabel, reflejado en su visita de 1487, no vamos aquí a tratar; pero sí hemos de recordar que Fernando el Católico envió en 1512 al Obispo de Cuenca, Ramírez de Villaescusa, para tantear una reforma. En 1529, bajo el rectorado de Pérez de Oliva, asistimos a un proceso similar, cuya profundidad aun está discutiéndose. En 1538, en pleno reinado de Carlos V, se establecerán los famosos Estatutos que estarán vigentes durante más de veinte años. En 1550, el Consejo Real envía al Obispo de Coria, Diego Enríquez de Almansa, con el mismo intento reformador, como en el presente trabajo podremos comprobar.

Para ello, a partir de los datos del concurso-oposición de 2010 para la selección de auxiliares administrativos en el Gobierno Vasco se estudiaron dos cuestiones: a la validez predictiva de los predictores empleados y b la justicia percibida por parte de los auxiliares con respecto al proceso selectivo y a las pruebas empleadas y su relación con el resultado en las mismas y el desempeño laboral. Los resultados muestran que la prueba de conocimientos es el mejor predictor del desempeño y que las reacciones de los candidatos presentan una correlación positiva con el desempeño laboral y con el resultado en el test de juicio situacional. Se comentan las limitaciones de la investigación así como las implicaciones prácticas de los resultados.

    Full Text Available La eficacia protectora de la actual vacuna (BCG contra la tuberculosis, para contrarrestar las formas pulmonares de esta enfermedad y su reactivación, resulta variable o poco eficiente, lo cual impone la búsqueda urgente de nuevas alternativas profilácticas contra esta enfermedad. Basados en las ventajas inmunogénicas que ofrece el uso de vacunas vivas, se han encaminado diferentes estrategias de este tipo empleando mutantes auxotróficos de Mycobacterium tuberculosis , BCG recombinante o micobacterias no tuberculosas. Existen evidencias experimentales acerca de la protección conferida tras la vacunación con cepas vivas, inactivadas o fracciones proteicas de Mycobacterium'habana' TMC-5135 contra la infección por Mycobacterium tuberculosis. Esta respuesta protectora parece ir aparejada de escasos signos de virulencia en los modelos animales ensayados, lo cual coloca a M.´habana´ dentro de los posibles candidatos vacunales contra la tuberculosis al ajustarse a la condición que impone una vacuna clásica de reproducir la infección y los eventos inmunes que le suceden lo más fielmente posible a como ocurren de manera natural, sin causar extensos daños en el receptor.

A pesar de un riguroso enmascaramiento tanto de las secuencias protéicas de P. falciparum, como del genoma de P. vivax, en este último fue evidente una alta presencia de regiones repetitivas que no fueron enmascaradas por ninguna de las fuentes de ADN repetitivo presente en la base de datos de REPBASE, lo cual lleva a pensar que dichas regiones pueden ser específicas de este tipo de organismos. Finalmente se encontraron coincidencias entre 76 secuencias proteicas con actividad antigénica de P. falciparum y el genoma hasta ahora secuenciado de P. vivax, que cumplían con los requisitos mínimos para establecer los niveles de coincidencia, entre las cuales se determinó que cuatro constituyen importantes candidatos a una vacuna contra la malaria producida por P. vivax.

    2015-06-01

    Full Text Available El Estatuto Básico del Empleado Público, lejos de aclarar el sistema de ordenación de los recursos humanos en las Administraciones públicas, abre la puerta a que puedan generarse diversos modelos de función pública. De igual forma, en el ámbito local la carencia de una regulación sistemática del estatuto de funcionarios propios al servicio de las Administraciones locales hace necesario extraer de las normas estatales su contenido básico que, por otro lado, se ha venido constatado por la propia realidad administrativa de las Corporaciones locales: todas poseen o una RPT o un catálogo de puestos de trabajo y, desde luego, una plantilla. Por otro lado, se aborda, desde un punto vista meramente introductorio, el impacto del concepto y contenido de las relaciones de puestos de trabajo en el estatuto funcionarial local y las consecuencias para la carrera de éstos. The Basic Statute of Public Employees, far from clarifying the system of management of human resources in public administrations, opens the door to various models that can be generated for public service. Similarly, at the local level the lack of a systematic regulation of the status of themselves in the service of local government officials is necessary to extract the basic content rules state, on the other hand, has been noted by the administrative reality itself of the local governments: all have or RPT or a catalog of jobs and, of course, a template. On the other hand, is discussed from a view point merely introductory, the impact of the concept and content of relations jobs in the local civil service status and career implications of them.

    Full Text Available The centrality of the media in the contemporary public sphere has led political institutions to adapt their communication strategies to its logic. Politics and entertainment are increasingly converging and one of the most significant examples of this trend is the tendency to turn politicians into celebrities, i.e. using elements of celebrity culture to build candidates’ public image. This article aims to develop theoretically what celebrification of a candidate means. Drawing upon the main contributions of celebrity studies and political marketing, we identify three fundamental aspects that become useful to recognise and understand celebrification. Additionally, these three elements are applied to analyse the construction of the candidates’ image in the 2012 Catalan Parliamentary Elections.A causa del rol central de los medios de comunicación en la configuración de la esfera pública contemporánea, las estrategias de comunicación de las instituciones políticas tienden a adaptarse a la lógica mediática. Se detecta un acercamiento progresivo de la comunicación política hacia el entretenimiento y el ejemplo más significativo de esta tendencia es la celebrificación de los políticos, es decir, el uso de elementos de la cultura de la fama para construir la imagen pública de los candidatos. El presente artículo tiene como objetivo desarrollar teóricamente qué significa celebrificar a los candidatos. A partir de las principales aportaciones de los celebrity studies y el marketing político se han identificado tres variables que permiten reconocer y entender la celebrificación. Posteriormente estos tres rasgos se usan para analizar la construcción de la imagen de los candidatos en las Elecciones al Parlamento de Cataluña de 2012.

    Full Text Available Cada día hay más secuencias genómicas completas de un gran número de patógenos humanos. La disponibilidad de estas secuencias ha cambiado completamente el panorama para el desarrollo de vacunas, introduciendo una nueva línea de pensamiento en este proceso. Esta metodología comienza por la secuencia genómica y mediante un análisis computacional se predicen aquellos antígenos más probables a ser candidatos vacunales. Por ejemplo, con el uso de herramientas bioinformáticas se puede hacer un pesquisaje in silico de aquellas proteínas expuestas en la superficie bacteriana, con vistas a identificar antígenos candidatos vacunales. La confirmación in vitro de estos resultados de localización celular y el uso de modelos animales para evaluar la inmunogenicidad de los candidatos acota finalmente el número de candidatos definidos por la computadora. A este proceso, aplicado por primera vez a Neisseria meningitidis serogrupo B, se le denomina vacunología inversa. La genómica también brinda información sobre la biología y la virulencia de especies patogénicas mediante la genómica comparativa. En este trabajo de revisión, describimos cómo la genómica puede ser usada en la identificación de nuevos candidatos vacunales.

    2016-08-01

    Full Text Available Tradicionalmente a partícula ‘nem’ tem sido considerada uma conjunção aditiva, pois se entende que estabelece entre elementos uma relação de acréscimo. Etimologicamente, é proveniente do latim ‘nec’, um dos poucos juntores que restaram nas variedades vernáculas de latim, juntamente com ‘et’, ‘aut’, ‘magis’, ‘ca’, ‘post’ (cf. Nascentes, 1955. Para Neves (2000, ‘nem’ tem o mesmo papel de ‘e’, ou seja, é uma conjunção que marca uma relação de adição entre segmentos negativos coordenados, com significado básico de “e também não”. Como se pode observar, a autora considera ‘nem’ um elemento complexo, indicando acréscimo por meio de ‘e’ e ‘também’, e negação, por meio de ‘não’. Este trabalho tem como objetivo discutir o estatuto desse elemento, utilizando o aparato teórico da Gramática Discursivo-Funcional (HENGEVELD; MACKENZIE, 2008, tendo como hipótese a de que ‘nem’, tal como ‘não’, representa, morfossintaticamente, o operador de polaridade negativa, acrescida, no entanto, de ênfase. Para isso, utiliza o córpus do Projeto PHPB, constituído de documentos escritos no Brasil, dos séculos XVII ao XX. Os dados analisados revelam que ‘nem’ pode ocorrer numa relação de justaposição entre atos discursivos, ou entre termos de diferentes categorias semânticas, e representa, além da negação, uma estratégia de intensificação, utilizada pelo Falante para atingir seu propósito comunicativo.

    noturno mostrou-se significativo e com o sinal negativo esperado.La reforma más profunda ocurrida en las universidades públicas durante la última década recae sobre la introducción de programas de acción afirmativa, con el objeto de ampliar las oportunidades de los negros en el ingreso a la universidad. Actualmente se quiere ampliar el número de los beneficiados, incluyendo a los candidatos que hayan cursado la enseñanza media en escuelas públicas. Existe una diversidad de programas, lo que refleja la autonomía de las universidades al definir, principalmente el grupo focal y el mecanismo que favorece a los estudiantes de ese grupo. Ese mecanismo puede ser el sistema de cuotas o el sistema de bonus o bonificaciones. El sistema de cuotas reserva un porcentaje de vacantes en cada carrera para los candidatos cuotistas clasificados; ya la bonificación agrega al puntaje del candidato cuotista un porcentaje que puede ser fijo o variable. En el caso del bonus, los beneficiados son estudiantes que cursaron la enseñanza media. Es inevitable que haya un conflicto entre eficiencia y equidad en la implantación de un sistema de cuotas. La pérdida de eficiencia está en la selección de candidatos con un puntaje menor. En este caso, el puntaje obtenido en el examen de ingreso es visto como un indicador de desempeño en el curso. El beneficio que trajo la equidad refleja las mayores oportunidades de acceso para los cuotistas. Los resultados empíricos refuerzan la importancia del ambiente familiar en el desempeño de los candidatos. Dicho ambiente se retrata por la escolaridad paterna y por la renta familiar. El prestigio académico, medido por el puntaje de los candidatos inscriptos en cada carrera, también tiene un comportamiento expresivo y, según parece, representa el capital cultural exigido en cada carrera. Los candidatos que eligen las carreras de mayor prestigio tienen mayores oportunidades de ser aprobados. No se observó alguna correlación entre las variables

    Full Text Available En Europa convive una multitud de regímenes jurídicos diferentes respecto del reconocimiento de efectos de la filiación del menor determinada en el extranjero a partir de un contrato de gestación por sustitución. Buena parte de esos derechos mantienen una estricta prohibición del contrato. La ausencia de reconocimiento tiene importantes consecuencias sobre el menor, sobre su vida privada y familiar, como ha puesto de manifiesto el Tribunal Europeo de Derechos Humanos. Al no ver reconocida la filiación en relación con sus padres de intención sus derechos políticos, civiles y sociales pueden verse gravemente afectados. Resulta así necesario establecer un estatuto jurídico homogéneo que permita resolver los problemas que plantea esta situación.

    Full Text Available RESUMO Introdução: Pequenos jogos são utilizados no treinamento de jogadores de futebol porque replicam as demandas técnicas, táticas, físicas e fisiológicas num contexto semelhante ao do jogo. Contudo, não se sabe se esse modo de treinamento é suficiente para demandar as especificidades observadas no jogo com relação ao estatuto posicional. Objetivo: Comparar a demanda física de defensores, meio-campistas e atacantes durante a realização de pequenos jogos de futebol. Métodos: Dezoito jovens jogadores de futebol (16,4 anos participaram do estudo, divididos em seis equipes compostas por um defensor, um meio-campista e um atacante. Realizaram-se seis sessões de coleta de dados constituídas por duas séries de quatro minutos com quatro minutos de pausa passiva. Utilizou-se equipamento de GPS de 15 Hz para coleta das informações. Os dados foram analisados por meio da ANOVA One-way e teste de Kruskal-Wallis, com nível de significância em 5%. Resultados: Observou-se diferença significativa na demanda física de jogadores de diferentes estatutos posicionais. Meio-campistas percorreram maior percentual da distância em velocidades superiores, enquanto defensores apresentaram distância total reduzida, aumento da distância na velocidade inferior e redução na realização de ações de aceleração. Conclusão: Demandas físicas variam durante a realização de pequenos jogos em função do estatuto posicional.

    Full Text Available O Estatuto da Igualdade Racial é uma lei sancionada em 2010, que, como tal, reflete anseios da sociedade brasileira no tocante à questão racial. Por outro lado, o fato de ter sido sancionada em pleno século XXI indica que a discussão sobre igualdade social e racial ainda precisa ser amadurecida. Os entraves que se apresentam para a discussão desta questão e, principalmente, para a implementação de ações efetivas no combate às desigualdades raciais estão relacionados a uma ideologia que vem sendo reproduzida ao longo da história do país, implicando na invisibilidade do tema, a despeito da realidade concreta de desigualdades que assolam a população negra. Neste contexto, este trabalho procura verificar o que o Estatuto da Igualdade Racial pode dizer a respeito da sociedade brasileira com relação à questão racial.

    2014-06-01

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

    Full Text Available En Nuevo León, se tiene por primera vez un candidato independiente a la gubernatura del estado en el proceso electoral de 2015. Este hecho inédito fue producido principalmente por la reforma electoral de 2013-2014, que incluyó esta figura para competir por cargos de elección popular. Sin embargo, las condiciones iniciales en la contienda fueron desventajosas para el candidato independiente, sobre todo en lo relativo al financiamiento y acceso a los medios de comunicación, por lo que éste basó su estrategia de campaña en las redes sociales, enfatizando el uso del marketing de emociones con mayor ventaja que sus contrincantes principales del Partido Revolucionario Institucional (PRI y del Partido Acción Nacional (PAN. El análisis que aquí se muestra está enfocado a medir el impacto que se tuvo de las campañas en redes sociales en la interacción con los usuarios, aunque no pueda ser todavía concluyente para inferir que esta variable fue la más determinante en la victoria del candidato independiente. / The state of Nuevo León for the first time saw an independent candidate running in the 2015 gubernatorial race. This unprecedented circumstance resulted mainly from the 2013-2014 electoral reform, which included the category of independent candidates for elected posts. However, conditions at the beginning of the race were disadvantageous for the independent candidate, above all with regard to financing and media access. That is why he based his campaign strategy on social networks, emphasizing the use of marketing emotions to better effect than his main opponents from the Institutional Revolutionary Party (PRI and the National Action Party (PAN. The analysis presented here focuses on measuring the impact the social network campaigns had on the interaction with users, although it is still too early to conclude that this variable was the determining factor in the independent candidate’s victory.

El marco teórico fue el modelo de la Rueda de Resiliencia de Hender son y Milstein. Los participantes fueron seleccionados de la población de estudiantes de práctica docente del nivel elemental y secundario de un recinto de una universidad privada. El diseño fue cualitativo hermenéutico y se utilizó la técnica de entrevist as de grupo focal. Cuatro grupos focales se configuraron: dos para explorar los conocimientos y experiencias de los participantes del nivel elemental y dos para el nivel secundario. Los hallazgos más significativos recayeron en la falta de conocimiento del concepto resiliencia. A pesar de esta falta de conocimiento, la mayoría de los participantes (70% mencionaron la aplicación de diversas prácticas que se relacionan con la promoción de la resiliencia educativa y enfatizaron la importancia que tenía para e llos el establecimiento de una relación estudiante - docente caracterizada por apoyo y afecto. Sin embargo, menos del 50% de los candidatos a maestro expresó la aplicación de las siguientes prácticas que promueven la resiliencia: Enseñar destrezas de asertiv idad, implantar tutorías entre pares y promover las actividades extracurriculares. Los participantes indicaron la necesidad de recibir mayor preparación en el entendimiento de qué es la resiliencia y en cómo promover la resiliencia educativa.

    Full Text Available Objetivo del artículo es describir el estatuto científico de la Glotodidáetica, siguiendo algunos enfoques desde los que se abordan otras ciencias en la epistemología piagetiana: 1 enfoque léxico semántico; 2 enfoque histórico; 3 enfoque sistémico. Dilucidar el estatuto científico de la Glotodidáctica es de capital importancia para la enseñanza de las lenguas. En este sentido, se plantean algunos interrogantes fundamentales: ¿la Glotodidáctica es una ciencia o una técnica?, ¿una teoría o una praxis?; ¿es una ciencia autónoma o depende de otras ciencias?; ¿es un saber derivado de la Didáctica General o es históricamente anterior a ella? ¿Cuál es su objeto propio de estudio (que le pertenece en propiedad? La respuesta a estos interrogantes es previa a la construcción de un curriculum lingüístico. Si la Didáctica puede concebirse como una metodología de la enseñanza, el análisis de los componentes del método nos permitirá dilucidar el carácter científico de la Glotodidáctica. Pero el método viene modulado por el objeto. En nuestro caso, el objeto es la adquisición de habilidades lingüísticas por un sujeto en un contexto sociocultural. La consideración de los elementos que estructuran el objeto será decisiva para determinar el carácter científico de la Glotodidáctica.

El debate se prolongó durante la segunda mitad del siglo xv, imponiéndose a la larga quienes propugnaban la adopción de medidas restrictivas para con la actuación pública de los cristianos nuevos, que cristalizarían en el apartamiento de los judaizantes y de sus descendientes del ejercicio de oficios públicos y en la aparición de los «estatutos de limpieza de sangre», ya en vísperas de la Modernidad.The integration process of the jewish converts in the christian spanish society was highiy controversial and it suppoused one of the most relevant sub¡ects in the Castile of the XV century.

    Full Text Available INTRODUÇÃO: O trabalho analisou redações sobre alcoolismo de candidatos a dezessete cursos no vestibular de 1996 na Universidade Federal do Espírito Santo. O objetivo foi identificar concepções sobre causas, conseqüências e propostas de intervenção em relação ao fenômeno do alcoolismo. MÉTODOS: Foram analisadas 2.578 redações (47,7%. Na organização dos dados foi usado um roteiro contendo categorias de causas, conseqüências e propostas de intervenção, construído a partir do exame de um conjunto de redações. RESULTADOS: Os sujeitos mostraram concepções que enfatizam o papel da bebida alcoólica no lidar com situações de caráter negativo e o papel da pressão social como fatores causadores do alcoolismo. Entre as conseqüências do alcoolismo apareceram com destaque as familiares, as psíquicas e a dependência. Como proposta para lidar com o alcoolismo aparece com bastante destaque o conjunto de providências incluídas sob o rótulo mudanças nas políticas públicas em relação ao comércio e à propaganda de bebidas alcoólicas e também em relação à difusão de informações adequadas sobre as conseqüências prejudiciais do consumo de tais substâncias. CONCLUSÕES: As concepções são similares em todos os grupos de cursos pretendidos pelos candidatos e oscilam entre uma compreensão moral-legal e uma compreensão médico-social do fenômeno.

  14. Sobre o estatuto epistemológico da racionalidade econômica segundo Karl Popper

    Directory of Open Access Journals (Sweden)

    Brena Paula Magno Fernandez

    2014-12-01

    Full Text Available Três tipos de críticas são comumente levantadas contra a utilização do postulado da racionalidade na ciência econômica. A primeira delas associa-se ao argumento da circularidade, a segunda diz respeito à blindagem da teoria contra a refutação e a terceira - e mais importante delas - refere-se à inadequação empírica. O presente artigo busca encaminhar esta última, à luz do tratamento dado por Popper ao longo de sua carreira para a questão de qual seria o estatuto epistemológico do princípio da racionalidade nas teorias econômicas. Três possíveis respostas a esta questão são aqui examinadas, explicitando-se suas respectivas estruturas lógicas. A primeira delas propõe que o postulado da racionalidade desempenhe o papel de lei geral do comportamento humano. A segunda requer que ele funcione como um axioma da teoria. Finalmente, a terceira proposta sugere que o postulado da racionalidade seja entendido como regra metodológica. Conclui-se o artigo sugerindo que esta última solução satisfaz ao apelo que o tipo de crítica aqui examinada faz ao conceito de racionalidade.

    Full Text Available La esquizofrenia es una de las enfermedades mentales severas que afecta a un 1% de la población mundial. Es claro que en su etiología participan factores genéticos y ambientales. Sin embargo, la identificación de genes de susceptibilidad ha sido difícil y no hay resultados inequívocos. A pesar de esto, en los últimos años se han identificado un grupo de genes candidatos por su posible fisiopatología o por estudios de asociación y ligamiento. En este artículo se revisa el papel de estos genes y los resultados de los estudios realizados en Costa Rica por nuestro grupo.Genetics of Schizophrenia: advances in the study of candidate genes. Schizophrenia is one of the most severe mental disorders that affect 1% of the population worldwide. It is clear that both genetic and environmental factors participate in its etiology. Nonetheless, the effort to identify susceptibility genes has been difficult and there are no unequivocal findings until now. Notwithstanding this, during the last couple of years, a group of candidate genes has been identified because of their possible role in the physiopathology or by association and linkage studies. In this article, the role of these genes is summarized as well as the results of the studies conducted in Costa Rica by our group. Rev. Biol. Trop. 52(3: 467-473. Epub 2004 Dic 15.

    Full Text Available Tomando como punto de partida la discusión de Canguilhem relativa al estatuto epistemológico del concepto de salud, pretendemos problematizar las conceptualizaciones dada por la OMS y una definición ampliada enunciada por la VIII Conferencia Nacional de Salud que se han convertido hoy en hegemónicas. Esas conceptualizaciones entienden la salud como equilibrio y adaptación al medio. Nuestro objetivo fundamental es evidenciar que el ámbito de los enunciados está en permanente cruzamiento con el ámbito de lo no discursivo, de lo institucional. Siendo así, la aceptación de determinado concepto de salud implica el direccionamiento de determinadas políticas y de ciertas intervenciones efectivas sobre el cuerpo y la vida de los sujetos.Taking as a point of departure Canguilhem's view on the epistemological status of the concept of health, the article examines current hegemonic concepts which see health as a question of balance and adjustment to the environment-including herein the conceptualization posed by the World Health Organization and the broad definition laid out during the 8th Health Conference. The basic goal of this examination is to show that what is defined in discursive statements constitutes an ongoing interaction with the metadiscursive statements more closely related to the world of institutions and institutional action. It is therefore argued that the adoption of a particular notion of health implies the selection of a particular direction in health care policies as well as the application of a particular set of intervention strategies regarding the lives and bodies of subjects.

    Full Text Available La inmunogenicidad es un parámetro importante en estudios de inmunógenos. En la leptospirosis la respuesta inmune humoral es vital para la resistencia a la infección, de ahí que este trabajo se haya propuesto evaluar la inmunogenicidad y la capacidad protectora homóloga de un candidato tetravalente que incluye al serogrupo Ballum en su formulación. Se trabajó con la cepa 245-12 clasificada como L. borgpetersenii serovar Ballum, aislada a partir de un caso confirmado de leptospirosis. Con esta cepa previamente caracterizada desde el punto de vista de su virulencia, se formularon 5 lotes de una preparación vacunal tetravalente, la cual contiene además las cepas Canicola, Icterohaemorrhagiae y Pomona contenidas en la vacuna Polivalente-Leptospira, de uso veterinario. Se evaluó la inmunogenicidad de esta preparación, mediante microaglutinación y la capacidad de protección homóloga en hámster sirio dorado, frente al reto con 100 DL50. Los animales se inmunizaron con dos dosis de la vacuna (0,1mL con un intervalo de 15 días, el reto se llevó a cabo a los 14 días de concluido el esquema de inmunización. Los resultados obtenidos se compararon con los de la vacuna Polivalente-Leptospira. Todos los lotes de preparación tetravalente formulados cumplieron satisfactoriamente con los controles de calidad. Los lotes formulados en este estudio mostraron una significativa inmunogenicidad y capacidad de protección homologa frente al serogrupo Ballum, y lograron eliminar el estado de portador en los animales inmunizados. El presente trabajo, por primera vez, sienta las bases para formulaciones vacunales novedosas, en animales, conteniendo el serogrupo Ballum.

    Full Text Available O artigo é fruto das reflexões e vivências do Estágio Curricular Supervisionado II de Ciências Biológicas, da Universidade Federal de Goiás, em que se discutiu o ensino de Ciências/Física para o ensino fundamental, sob uma abordagem histórica, a partir dos Estatutos do Conhecimento Biológico (ECB, Ontológico (EO, Epistemológico (EE, Histórico-Social (EHS e Conceitual (EC, propostos por Nascimento-Jr. Essas reflexões abordam aspectos vivenciados durante o período de regência em turmas de 9º ano do Ensino Fundamental, e se relacionam ao uso de estratégias de ensino na prática pedagógica e aos caminhos possíveis para o ensino de Ciências/Física, a partir dos Estatutos do Conhecimento. Foram discutidos com os estudantes a História e Filosofia da Ciência a partir de conteúdos de eletricidade, eletromagnetismo e sistema solar, construindo uma visão não reducionista, não linear e nem a-histórica. Os desafios encontrados foram grandes, mas mostram que é possível construir estratégias que busquem desafiar a construção do conhecimento para além da transmissão de conteúdos.

    Full Text Available Embora no "Projeto" freudiano não seja oferecida, de uma maneira explícita, uma conceituação a respeito do estatuto do psicológico, pensamos que é possível delinear esse estatuto e tentaremos fazê-lo com base em uma maneira de interpretar o modelo do psiquismo que é construído no texto freudiano. Isto levar-nos-á também a situar o "Projeto" em relação ao clássico problema mente-corpo. Pretendemos dar conta da tarefa proposta apoiando-nos, sobretudo, em uma distinção que estabeleceremos entre o representar, entendido como ato intencional, e a representação, entendida como traço de memória. Também contemplaremos a forma de comportamento do fator quantitativo-energético nas ordens processuais do psicológico e do neurofisiológico.

El marco de reflexión del tema es el aún vigente planteamiento sobre la transición política mexicana y si esto ha sido posible al interior de los partidos, o si se trata sólo de una recomposición de los grupos políticos y/o clase política atendiendo a prácticas políticas de viejo cuño. Así, los resultados de la indagación a través de entrevistas, consultas hemerográficas y documentos institucionales, ayudarán a discutir de forma cualitativa con base en los datos empíricos de caso, hasta qué punto y/o de qué forma dicha transición política ha sido efectiva o concretada y si ha abonado a la democracia mexicana y particularmente al trabajo interno de los propios partidos políticos. Lo anterior independientemente que desde la formalidad del proceso electivo, los resultados indican el triunfo del PRI como resultado de las elecciones del 2015.

  10. Propostas de redução da idade penal no Brasil e o Estatuto da Criança e do Adolescente

    Directory of Open Access Journals (Sweden)

    Aline Kelly da Silva

    Full Text Available Neste artigo discutimos como as propostas de redução da idade penal no Brasil tensionam o Estatuto da Criança e do Adolescente. A partir da genealogia e da arqueologia propostas por Michel Foucault analisamos as Propostas de Emenda Constitucional apresentadas pela Câmara de Deputados entre os anos de 1993 e 2013. Nossa análise indica que as propostas criticam o critério cronológico adotado pelo Estatuto e propõem sua substituição pelo que chamam de critério subjetivo-psicológico. Postos em oposição aos direitos sociais, os direitos civis são tomados como balizadores de uma responsabilização dos sujeitos jovens, tornando-os mais penalizáveis. Por fim, as propostas fazem uma série de críticas à ineficácia do Estatuto da Criança e do Adolescente. Essas críticas não são produzidas no sentido de ampliar a efetivação das atuais políticas, mas de instrumentar o recrudescimento punitivo a partir da desqualificação do Estatuto.

El modelo presentado permite construir una clasificación de la influencia personalista de los candidatos, como resto no explicado por una competencia ideológica espacial. Además de clasificar a los candidatos de las tres últimas elecciones presidenciales por su influencia personal, se ofrecen previsiones para futuros comicios tomando como base el cambio de la distribución ideológica. Para la construcción del modelo, se consideran los supuestos de voto ideológico simétrico y una sola dimensión. / This research project presents a spatial competition model for Venezuelan presidential elections based on the effective number of parties and weighted and scalar polarization indices. The model makes it possible to construct a classification of candidates’ influence based on personality as an remainder unexplained by spatial ideological competition. In addition to classifying the candidates in the last three presidential elections by their personal influence, the authors offer predictions for future balloting based on change in ideological distribution. Suppositions of symmetrical ideological votes and a single dimension were used to build the model.

  13. Participação política e gestão urbana sob o Estatuto da Cidade

    Directory of Open Access Journals (Sweden)

    Jefferson Oliveira Goulart

    2014-01-01

    Full Text Available A versão hegemônica da democracia tem inspiração na abordagem de Schumpeter, legado do pluralismo liberal que a reduz à formação de maiorias legítimas por meio da representação. Não obstante, a democratização de países que passaram pelo autoritarismo proporcionou experiências inovadoras da sociedade civil em novos formatos participativos. No Brasil, essa experimentação tem particular expressão em nível municipal. No plano institucional, o Estatuto da Cidade regulamentou o capítulo da Política Urbana da Constituição Federal de 1988 e preconiza formatos participativos de políticas públicas de gestão urbana “por meio da participação pública e as associações representativas”. A construção dessa agenda resulta de imposição institucional e reflete decisões governamentais e demandas da sociedade civil. O texto analisa a participação, seu alcance para compartilhar decisões e em que medida esses formatos participativos dependem dos governos na implantação de novos paradigmas de gestão urbana. A abordagem combina análise teórica e empírica de processos de elaboração de Planos Diretores orientados normativamente pelo Estatuto da Cidade. A base empírica é formada por três cidades médias do interior paulista: Piracicaba, Bauru e Rio Claro.

    Full Text Available Lack of the use of urban property for individual benefit lets the land market act as the major force structuring the city. Within this context, the urban poor are excluded from the benefits of urbanizationand makes its way into the city’s territory through irregular occupation. Facing such situation, this paper presents an analysis of the city of Curitiba, Paraná, from the standpoint of the land market and its relationship to the urban structuring process, in order to demonstrate how the capitalist city segregates and excludes that share of the population whose income does not allow them access to the formal land market. The paper analyzes the possibilities of Federal Law 10.257/01 – Estatuto da Cidade – to intervene on the logics of the land market, thus recovering the discussions about urban reform and creating prospects for the fulfillment of the city’s social function. Finally, this paper attempts to identify possibilities and limits of public policies on the production of space in order to contribute to the overcoming of the sociospatial segregation and consequently to the improvement of life conditions in the city.

    2014-01-01

    Full Text Available As perseguições contra os cristãos constituem um dos acontecimentos mais estudados na História do Cristianismo e na História de Roma. A esse respeito, são inúmeros os documentos existentes desde o início do segundo século de nossa era, tanto da parte dos pagãos, como da parte dos cristãos. Tomando esses documentos por base, cabe a pergunta: qual foi o estatuto jurídico no qual se basearam as autoridades romanas para perseguir os cristãos? Procuro mostrar, neste texto, que de início eram aplicadas contra eles as leis criminais vigentes. Só mais tarde se tornou crime o fato de ser cristão. Mas leis persecutórias válidas em todo o império apenas surgiram a partir do ano 250, e foram abolidas em 313.

    Full Text Available El artículo hace un recuento de la forma como la teoría económica ha incorporado las dimensiones de niñez y juventud. Se diferencian tres espacios temáticos: el primero corresponde al método de la economía; el segundo se refiere a la ruptura que hace Samuelson con el utilitarismo clásico y el tercero muestra alternativas posibles al marco de análisis de Samuelson. Entre los caminos factibles se destacan tres: el primero, formulado por Arrow, abre el espacio samuelsoniano porque propone los estados del mundo como argumentos de la función de utilidad. El segundo camino, relacionado con el nombre de Simon, conjuga biología y economía. Y la tercera vía, estimulada por Sen, está centrada en las capacidades. A medida que la reflexión se distancia de Samuelson, se amplían las posibilidades de incorporar las dimensiones de la niñez y de la juventud en la reflexión económica, pero esta opción obliga a tener una visión interdisciplinar que está ausente en la discusión convencional. El artículo termina con un breve comentario sobre las políticas públicas, e invita al diálogo entre saberes, que es especialmente necesario en el campo de la niñez y la juventud.

    Full Text Available Purpose: To present how the section of Refractive Surgery of the Federal University of São Paulo assesses the candidates and the reasons to indicate for corneal refractive surgery. Methods: We examined 1626 patients. Anamnesis, complete ophthalmologic examination and corneal topography were performed in all patients. The patients spontaneously seeked evaluation at the Refractive Surgery Section by telephone without a previous screening. Reasons to refuse patients for refractive surgery were previously established by the Refractive Surgery Section. Results: Based on current technology and clinical experience, 265 patients (16.29% were refused for excimer laser corneal refractive surgery. Myopia of patients who had insufficient preoperative corneal pachymetry for the laser treatment was the main cause for refusal (51 patients. Cataract (45 patients, keratoconus (31 patients, amblyopia (21 patients, hyperopia > 5 diopters and mixed astigmatism (19 patients, presbyopia (unaware ness of the need for optical correction after the procedure; 16 patients, pupillary diameter > 5mm (9 patients, single eye (9 patients, progressive myopia (8 patients, postradial keratotomy (7 patients and low ametropia (7 patients were among the reasons for the refusal.

    Full Text Available En este documento se propicia una reflexión acerca de la forma en que la inmersión de las lenguas indígenas en preceptos de carácter legal y social confiere una dinámica particular a la realización de la educación formal destinada a amplios sectores de la población mexicana. Las interrogantes que se plantean a lo largo de la exposición son: ¿Cómo se traduce lo asentado en el plano jurídico en relación con el indígena en el marco de la educación indígena?, y ¿cómo se introduce la representación social del indígena en la educación formal diseñada para ellos? Para un acercamiento a las respuestas se indaga en los documentos oficiales que abordan el tema, en la revisión de datos censales y en algunos elementos teórico-metodológicos de la educación, las ciencias del lenguaje y la antropología. Las premisas de las cuales se parte son: 1 el auge de los movimientos indígenas ha golpeado a la hegemonía de las posiciones multiculturales y asimilacionistas; 2 los pueblos indígenas se han instalado como actores sociales en los escenarios políticos, y 3 la cuestión indígena no es un problema marginal. Exige una reforma del Estado y la participación de la sociedad civil. Un análisis fundamentado en la categoría de formación imaginaria propuesta por Michel Pécheux1 permite un acercamiento a la caracterización del sujeto indígena por sí mismo; del otro, sea o no indígena y del referente; es decir, de lengua y cultura. De éste se desprende que es necesaria una reformulación del estatuto legal, que sea acorde con los requerimientos de los diversos grupos indígenas, con el reconocimiento a la diversidad cultural.

Objetivo: Avaliar como as condições de personalidade e a dinâmica fami liar interagem no processo de decisão. Método: Mostramos cinco casos díspares no seu conteúdo e condução, o que nos leva à escolha de instrumentos pertinentes a cada um deles: nos dois primeiros somente entrevista com o paciente e sua mãe; no segundo, entrevista com a mãe, WISC, Colúmbia, Bender, provas pedagógicas e Wartegg no paciente, além de atendimentos em psicoterapia breve com ambos. No terceiro, entrevistas com pais e paciente, provas pedagógicas e Wartegg; no quarto, atendimento familiar, HTP e terapia com paciente. Resultados: O primeiro, 22 anos surdez congênita, bilíngue, com identificação bi-cultural, pais separados e discordantes em relação ao implante coclear, no entanto, espelhando-se numa amiga já implantada, o que a motivou para a cirurgia. Bons resultados pós-implante. O segundo, 17 anos, surdez pós-meningite aos quatro meses, maduro, mãe protetora, além de importante fi gura do avô. Bons resultados pós-implante. O terceiro, 13 anos, surdez congênita, família disfuncional que não acolhe seu filho, com desperdício de potencial, recusando- se ao uso de aparelho, rejeitado no momento para o implante. O quarto, 15 anos, surdez pós-meningite com 1 ano e 3 meses, encontra nos pais proteção, voltando- se para eles nos momentos de angústia, aceitando prognóstico limitado.

    Full Text Available El propósito de este artículo fue explorar los conocimientos y experiencias de estudiantes matriculados en la práctica docente de una universidad privada en Puerto Rico, sobre la implantación de prácticas en la sala de clases que contribuyan al desarrollo de la resiliencia educativa. El marco teórico fue el modelo de la Rueda de Resiliencia de Henderson y Milstein. Los participantes fueron seleccionados de la población de estudiantes de práctica docente del nivel elemental y secundario de un recinto de una universidad privada. El diseño fue cualitativo hermenéutico y se utilizó la técnica de entrevistas de grupo focal. Cuatro grupos focales se configuraron: dos para explorar los conocimientos y experiencias de los participantes del nivel elemental y dos para el nivel secundario. Los hallazgos más significativos recayeron en la falta de conocimiento del concepto resiliencia. A pesar de esta falta de conocimiento, la mayoría de los participantes (70% mencionaron la aplicación de diversas prácticas que se relacionan con la promoción de la resiliencia educativa y enfatizaron la importancia que tenía para ellos el establecimiento de una relación estudiante-docente caracterizada por apoyo y afecto. Sin embargo, menos del 50% de los candidatos a maestro expresó la aplicación de las siguientes prácticas que promueven la resiliencia: Enseñar destrezas de asertividad, implantar tutorías entre pares y promover las actividades extracurriculares. Los participantes indicaron la necesidad de recibir mayor preparación en el entendimiento de qué es la resiliencia y en cómo promover la resiliencia educativa. The purpose of this article was to explore the knowledge and experiences of students enrolled in a teacher preparation program at a private university in Puerto Rico, on their ability to implement strategies in the classroom that contribute to the development of educational resilience.

Nesse artigo refletimos acerca da tecnologia como um aspecto abordado no Estatuto da Criança e do Adolescente – ECA, por constituir, na atualidade, a formação desses sujeitos em desenvolvimento. Com esse preâmbulo introduzimos nosso objeto de pesquisa que investiga de que maneira a mídia está posta na lei 8.069/90. A forte presença dos aparelhos tecnológicos na vida da sociedade, mais especificamente na vida das crianças e dos adolescentes, ensejou compreender a mídia como opção de lazer e agentes de cultura, em que esses sujeitos estão imersos no mundo midiático, no qual crescem influenciados diariamente pelos meios de comunicação. Para contribuir com as reflexões, a pesquisa está ancorada nos Estudos Culturais e na lei 8.069/90 que se refere especificamente ao ECA.  O objetivo da pesquisa é de construir uma relação de análise entre a legislação que ampara as crianças e os adolescentes brasileiros e a abordagem midiática, como influência na construção da identidade dos sujeitos que estão na fase infantojuvenil. Como recurso metodológico optamos pela leitura do documento e textos específicos, tendo a internet como auxiliadora da investigação. Abordar o ECA é dialogar com um cenário multifacetado, a fim de que nossas lutas sejam pela garantia de direitos fundamentais desses sujeitos em formação. PALAVRAS-CHAVE: Criança e Adolescente; ECA; Mídia. ABSTRACT:   Modern life has immersed us in a world where technology greatly underpins social relationships.

    Full Text Available Resumo: O presente artigo discute como o Twitter, enquanto esfera pública, reproduz discursos que descrevem os candidatos a presidência, Aécio Neves (PSDB e Dilma Rousseff (PT, durante três debates presidenciais do segundo turno das eleições de 2014. Através de análise de contingência e de análise de redes sociais, discutimos um conjunto de dados obtido de forma automática da API do Twitter. Nossos resultados apontam para descrições negativas de ambos os candidatos, notadamente com relação à Dilma. Enquanto Aécio Neves recebe críticas relacionadas à sua atuação nos debates, Dilma Rousseff é criticada principalmente quanto a seu aspecto físico, e também quanto à sua capacidade intelectual e, por fim, quanto à sua atuação nos debates. Esses resultados apontam para uma tendência à presença de violência de gênero nos comentários negativos, focando preconceitos quanto à mulher no caso de Dilma.

    Full Text Available Em plena vigência da ditadura, em 30 de novembro de 1964, foi promulgado pelo governo militar de Humberto Alencar Castello Branco, o Estatuto da Terra, caracterizado enquanto um conjunto de dispositivos legais que definiam, entre outros fatores, o que era propriedade da terra no Brasil, bem como, os instrumentos necessários para se realizar a Reforma Agrária. Embora tenha sido aprovado pelo Congresso ainda no primeiro ano do governo, seu processo de elaboração e tramitação constituiu-se em um período de intensas discussões políticas acerca do alcance e da natureza que esta proposta deveria assumir.  Neste sentido, o presente artigo objetiva compreender as disputas políticas que ocorreram, mesmo sobre o regime de exceção, pela forma da Reforma Agrária. Para essa análise utilizamos, especialmente os discursos parlamentares proferidos nos meses que antecederam a aprovação da lei e as colunas publicadas na grande imprensa, pois essas fontes possibilitam refletir sobre os posicionamentos de diversos agentes envolvidos, como: políticos, associações patronais e o governo.

    Full Text Available La definición clásica de refugiado ha sido puesta a prueba por los eventos de un mundo en constante cambio frente a la necesidad de protección internacional cuando aquella proporcionada por el Estado de nacionalidad o de residencia habitual no resulta efectiva. Los desplazamientos masivos de población originados por conflictos armados, pusieron a prueba el estatuto de refugiado a partir de interpretaciones regionales que amplían los supuestos de protección internacional. Sumado a ello, encontramos el desarrollo sobre violencia basada en el género de las teorías feministas en dichos contextos. En este trabajo analizamos la complementariedad del Derecho Internacional de los Derechos Humanos y el Derecho Internacional Humanitario a la luz del Derecho Internacional de los Refugiados, estableciendo la plena e irrestricta vigencia de la protección internacional en los casos de mujeres forzadas a desplazarse de sus países de origen, como consecuencia de una situación de conflicto armado.

    Full Text Available O objetivo deste estudo é analisar a real necessidade da intervenção fonoaudiológica por meio de avaliação/documentação e sessões terapêuticas, no pré e pós-operatório de paciente candidato à cirurgia bariátrica. Este trabalho, um relato de caso transversal, descreve a documentação/avaliação e acompanhamento fonoaudiológico de um paciente do sexo masculino, 36 anos, 51 de IMC, apresentando comorbidades; submetido à cirurgia bariátrica pela técnica Fobi Capella. O mesmo, seguindo um protocolo previamente elaborado, foi submetido a uma avaliação fonoaudiológica do Sistema Estomatognático no pré e pós operatório de três meses, documentada por meio de fotos das estruturas dinâmicas, filmagens do sistema orofacial, medidas orofaciais e palpação dos músculos mastigatórios masseter e temporal. Após a primeira avaliação, recebeu orientações quanto à mastigação e exercícios oromiofuncionais. A análise comparativa das avaliações pré e pós-cirúrgicas indicaram melhora nos aspectos gerais das estruturas do Sistema Estomatognático e suas respectivas funções como de mastigação e respiração, persistindo algumas alterações que necessitam de acompanhamento fonoaudiológico para sua completa adequação e equilíbrio. Conclui-se que a documentação fonoaudiológica no protocolo de avaliação do candidato à cirurgia bariátrica, corrobora para uma atuação fonoaudiológica específica e científica, favorecendo ao paciente uma adaptação funcional oral satisfatória às suas novas características orgânicas (morfológicas e funcionais.

    Full Text Available Se investigó un programa de intervención psicológica a pacientes candidatos a cirugía bariátrica, evaluando estrategias de afrontamiento adoptadas, manifestaciones de ansiedad y cambios de estilo de vida, comparándolos a un grupo control. El programa cognitivo-conductual consiste en doce sesiones de grupo en el que se abordan cuestiones relacionadas con el proceso de cambio de hábitos y la preparación para la cirugía. La comparación entre las evaluaciones pre y posintervención y entre grupos mostró tendencias de mejoría en el grupo experimental; sin embargo, las variables de ansiedad empeoraron en algunos pacientes. Se destaca la importancia del tratamiento psicológico continuo como promotor de las habilidades necesarias para hacer frente a situaciones adversas de la obesidad y del tratamiento. Se sugiere para futuras intervenciones estudios con muestras más grandes, y mayor atención a variables de ansiedad.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Devido à sua prevalência, a doença arterial coronariana (DAC constitui a principal causa de morbimortalidade em cirurgias eletivas, o que justifica a presente revisão, cujo objetivo foi principalmente estabelecer condutas pré-operatórias baseadas em normas e diretrizes para minimizar a morbimortalidade peri e pós-operatória dos portadores de DAC. CONTEÚDO: São apresentadas características gerais da DAC, assim como seus mecanismos fisiopatogênicos, as principais variáveis relacionadas ao preparo pré-operatório de pacientes com DAC, bem como condutas frente aos enfermos de maior risco cirúrgico. CONCLUSÕES: Portadores de DAC candidatos à cirurgia não cardíaca devem ser rigorosamente avaliados. Os identificados como de alto risco podem beneficiar-se com testes pré-operatórios provocativos de isquemia miocárdica, assim como de intervenções coronarianas invasivas, precedendo operações cirúrgicas eletivas. Em pacientes selecionados, deve-se considerar o uso de betabloqueador e de estatinas .

    Full Text Available O objetivo deste artigo é investigar uma das principais funções dos partidos políticos em uma democracia representativa: organizar e controlar a produção de representação. Para isso, dois processos intrapartidários serão examinados: a formação e manutenção da estrutura organizacional e a seleção de candidatos à Câmara dos Deputados realizados pelo PFL, PP, PMDB, PSDB e PT no estado de São Paulo. A proposição que orienta a análise é que quanto maior o controle dos partidos políticos sobre esses dois processos, maior será a vitalidade de suas organizações partidárias na dinâmica representativa.This paper aims to investigate one of the main roles of political parties in a representative democracy: to organize and to control the production of representation. In order to do that, two internal party processes will be examined: the setting and maintaining of the party's organizational structure and the candidate selection for the Camara dos Deputados in the state of Sao Paulo for the PFL, PP, PMDB, PSDB and PT parties. The analysis is based on the idea that the more control political parties have over these two processes, the more vital are their party organizations in the representative dynamics.

    2007-01-01

    Full Text Available En este artículo se analizan los procesos de selección de los candidatos profesionales en los partidos Liberal y Conservador colombianos durante el periodo 1974-2006. A partir del enfoque de la institucionalización organizativa, el texto aborda las características de estos procesos a través de tres dimensiones analíticas: la existencia de reglas de juego, su grado de aplicación y acatamiento por parte de los actores internos de los partidos. El argumento central es que ambos partidos presentan un precario proceso de institucionalización organizativa, el cual se expresa en la debilidad de sus procesos de rutinización de las reglas internas. Finaliza mostrando cómo los sucedido en las elecciones de 2002 y de 2006, en las que se puso en evidencia que el predominio histórico de los partidos Liberal y Conservador estaba siendo disputado por nuevos partidos, los ha obligado a encaminarse hacia su reestructuración y hacia la búsqueda de mayores niveles de institucionalización organizativa.

    2014-04-01

    Full Text Available El trabajo propone una hipótesis que busca ceñir la singularidad de todos los narradores en la obra de Juan José Saer. Para ello, traza una genealogía de la instancia narrativa saeriana como voz fenomenal. La categoría propuesta propone pensar al narrador saeriano como una relación conciencia-mundo en la cual se disuelve tanto la consistencia de la objetividad, presupuesto de la novela realista, como la consistencia de la subjetividad, presupuesto de la novela de vanguardia. El narrador saeriano plantea un tipo de interrogación que intenta disolver las certezas narrativas, incluso las negativas, para trabajar en el terreno raso de la experiencia, entendiendo por ésta la relación entre un sí-mismo sin subjetividad y un mundo de cosas que se desprende de sus determinaciones objetivantes.   Abstract   This work proposes a hypothesis that tries to stick to the singularity of every narrator in the work of Juan José Saer. For that, it traces a genealogy of Saer’s narrative instance as amazing voice. The proposed category suggests thinking about the Saer’s narrator as a relationship between conscience and world where both the consistency of objectivity, an estimation of the realist novel, and the consistency of subjectivity, an estimation of the vanguard novel, are dissolved. The Saer’s narrator sets a kind of interrogation that tries to separate the narrative truths, even the negative ones, to work on the flat ground of experience, understanding by this the relationship between oneself without subjectivity and a material world that can be deduced of its objectifying determinations.

    Full Text Available En el presente artículo se realiza un análisis de la figura del contrato por adhesión incluido en la Ley 1480 de 2011 desde un enfoque cualitativo, mediante el uso de la hermenéutica jurídica para interpretar sistemáticamente el alcance y sentido de las normas referidas a la contratación y al consumo, y así caracterizarlas en el sistema colombiano y en el derecho comparado: Argentina y Brasil. Además se analiza la novedad de la inclusión en esta normativa del concepto de relación de consumo, su relación con el contrato por adhesión, y su importancia dentro del marco jurídico del derecho del consumo trazado a partir de la redacción de los artículos 78 y 88 de la Constitución de 1991. Entre los resultados destaca la influencia de la tendencia finalista en la nueva legislación colombiana y la introducción de un esquema de protección contractual para los consumidores frente a los contratos predispuestos. Como conclusión, vale mencionar, el avance que esta Ley representa en el tema de las relaciones contractuales por adhesión y su relación con los consumidores: establece deberes, límites y cargas para el predisponente, protección contractual para los consumidores y los términos para las relaciones de consumo en el mercado colombiano.

    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 Se presenta la descripción de un método de extracción automática de candidatos a términos del área médica a partir del procesamiento de información lingüística. Para ello, se trabajó con reglas en el nivel léxico, morfológico y sintáctico. En primer lugar, se realizó la detección aplicando un diccionario estándar, el cual asignó a las palabras consideradas términos, la etiqueta MED (MÉDICO. Luego, para las palabras que no estaban contempladas en el diccionario (PNCD, se dedujeron las categorías gramaticales apelando a reglas morfológicas y sintácticas. Posteriormente, se procedió a la conformación de sintagmas nominales que involucraban PNCD y MED, para extraerlos como candidatos a términos del dominio. Se utilizaron los softwares Smorph y Módulo Post Smorph (MPS, que trabajan en bloque, y Xfst. Smoprh realiza el análisis morfológico y MPS trabaja sobre gramáticas locales. Xfst, por su parte, es una herramienta de estados finitos que opera sobre cadenas de caracteres, a las que asigna categorías previamente declaradas. El método se probó en una parte del corpus de casos clínicos compilado por Burdiles (2012, que contenía 217258 palabras, y los resultados arrojaron una precisión de 92,58%, una cobertura de 95,02% y una medida f de 93,78%.

    2005-01-01

    Full Text Available El artículo hace un recuento de la forma como la teoría económica ha incorporado las dimensiones de niñez y juventud. Se diferencian tres espacios temáticos: el primero corresponde al método de la economía; el segundo se refiere a la ruptura que hace Samuelson con el utilitarismo clásico y el tercero muestra alternativas posibles al marco de análisis de Samuelson. Entre los caminos factibles se destacan tres: el primero, formulado por Arrow, abre el espacio samuelsoniano porque propone los estados del mundo como argumentos de la función de utilidad. El segundo camino, relacionado con el nombre de Simon, conjuga biología y economía. Y la tercera vía, estimulada por Sen, está centrada en las capacidades. A medida que la reflexión se distancia de Samuelson, se amplían las posibilidades de incorporar las dimensiones de la niñez y de la juventud en la reflexión económica, pero esta opción obliga a tener una visión interdisciplinar que está ausente en la discusión convencional. El artículo termina con un breve comentario sobre las políticas públicas, e invita al diálogo entre saberes, que es especialmente necesario en el campo de la niñez y la juventud

Assim, foram efetuadas duas avaliações em momentos temporais distintos, assumindo-se um plano transversal de recolha de dados (2004/2005, n=689; 2008/2009, n=473. O protocolo de avaliação incluiu medidas de fontes de stress e de burnout. Os resultados indicaram que a experiência de stress e de burnout aumentou entre as duas avaliações. Foram encontrados, em 2008/2009, níveis mais altos em áreas relacionadas com pressões de tempo, excesso de trabalho e trabalho burocrático e administrativo; inversamente, houve diminuições em áreas relacionadas com as diferentes capacidades e motivações dos alunos. Quanto à predição da síndrome de burnout, não se verificaram alterações substanciais nas variáveis preditoras nos dois momentos. Em síntese, os resultados indicaram aumentos nas exigências profissionais dos professores, mas não se pode afirmar que tal se deva às alterações do Estatuto da Carreira Docente, uma vez que não observámos alterações no stress associado à carreira docente.This study was carried out with 1162 teachers with the objective of analyzing their experiences of stress and burnout syndrome before and after the change to the Portuguese Statute of the Teaching Career.

    Full Text Available Este artículo examina la cuestión de la cientificidad de la investigación pedagógica en el marco de los enfoques epistemológicos hermenéutico y crítico. Se plantea, en este horizonte, que las miradas hermenéutica y crítica, al permitirles a las ciencias sociales tomar distancia del modelo positivista de ciencia, han abierto un espacio fecundo para pensar la pedagogía como un campo de producción de conocimiento que puede ser agenciado por los docentes mismos. Es decir, que la investigación pedagógica -a diferencia de la investigación que toma como objeto a la educación para producir conocimiento sobre este campo y que se realiza desde miradas teóricas que no están ancladas en el trabajo educativo mismo- tiene consistencia y legitimidad en la medida en que construye su objeto en una vinculación profunda con la propia práctica. En este contexto, el artículo aborda, en primer lugar, los enfoques hermenéutico y crítico como marcos epistemológicos de la investigación pedagógica y, en segundo lugar, busca establecer la diferencia existente entre investigación educativa e investigación pedagógica.

Com o objetivo de descrever as referidas variedades, o trabalho avalia as motivações de natureza estrutural e social segundo os pressupostos da Teoria da Variação e Mudança (WEINREICH; LABOV; HERZOG, 1968. Os resultados das diferentes análises, desenvolvidas no âmbito do Projeto Estudo comparado dos padrões de concordância em variedades africanas, brasileiras e europeias do Português, sugerem que, embora as três variedades manifestem tendência à adoção da regra de concordância tanto no Sintagma Nominal quanto no Sintagma Verbal, a concordância apresenta estatuto diferenciado. No Português Europeu, os dados revelam um comportamento que não pode ser considerado efetivamente variável - trata-se, nos termos de Labov (2003, de uma regra categórica no âmbito da concordância nominal e semicategórica no âmbito da verbal; no Português do Brasil e no Português de São Tomé, ambas as regras são variáveis.

    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

Esse inventário mostrará que apesar de todos os pensadores em questão comungarem das mesmas idéias fi...

    Full Text Available O artigo tem como objeto o Estatuto da Cidade (Lei n. 10257/2001, enfatizando dois instrumentos de política urbana previstos na Lei do Meio Ambiente Artificial para valorização e proteção do patrimönio histórico: a outorga onerosa e a transferência do direito de construir. Trata-se da possibilidade de, em caso de tombamento, o proprietário do imóvel transferir seu direito de construir a outro imóvel, edificando acima do coeficiente básico de construção daquela região, sem a necessidade de pagar ao Poder Público. A pesquisa evidencia a importância de uma gestão voltada aos interesses de sua população, capaz de preservar tanto a sua história quanto desenvolver alternativas susstentáveis de desenvolvimento para as futuras gerações, criando alternativas legais para que o proprietário de imóvel tombado não tenha apenas ônus com o tombamento, mas também bônus. Para tanto o artigo analisa a gestào democrática municipal, a fim de demonstrar que a qualidade de vida das pessoas que habitam o meio urbano, bem como a preservação de seus laços históricos e culturais, trata-se de um processo compartilhado entre poder público e cidadãos.This paper has as its object of study the Statute of the City (Public Law 10257/2001, emphasizing two instruments of urban policy under the Law on Artificial Environment for the recovery and protection of historical property: the onerous grant and the transfer of the right to build. The possibility is opened that in the case of a property being listed as a historic building, the owner of the property transfers his right to construct to another building, constructing beyond the basic limits in his region, without the need to pay anything more to the Public Authorities. The research highlights the importance of pubic management oriented toward the interests of its people, able to preserve its history as well as developing sustainable alternatives of development for future generations by

Procuramos evidenciar a existência de um movimento marcado pelo encontro profícuo entre o campo da "Saúde Coletiva" e uma parcela do campo da "Alimentação e Nutrição", ou, mais precisamente, um dos seus núcleos, protagonizado por atores orientados por saberes diferenciados dos demais núcleos nesse campo. Tais fenômenos, que postulamos como desfechos do contato dos núcleos de saberes que identificam a Saúde Coletiva com o campo da "Alimentação e Nutrição", deram origem a um núcleo específico de saberes, bem como a práxis distintas, nesse âmbito correspondendo ao que denominamos "Alimentação e Nutrição em Saúde Coletiva". Trata-se de um processo marcado, desde o início, por tensões entre os paradigmas biológico e social, configurando-se, por um lado, como um importante desafio a ser enfrentado e, por outro, como um caminho promissor para a aproximação entre distintos campos da ciência, tanto os de cunho mais prático como os dirigidos à reflexão conceitual.This paper aims to examine the route on which Food and Nutrition in Public Health was build in the Brazilian context, from its fields of origin, identifying tensions and convergences, seeking to demarcate its boundaries and to characterize its status within the scientific field.

    Full Text Available Estudiar a los partidos en su carácter de organización, «iluminar hacia su interior», es un desafío aún pendiente en América Latina. Se pretende entonces contribuir analizando los procedimientos de selección de candidatos en Argentina, caso que demuestra que ni la descentralización a nivel organizativo ni una mayor inclusividad en los selectorados genera procesos de selección de candidatos más competitivos. Se presentan dos hipótesis: pensar la democratización de los procesos de selección de candidatos en términos de inclusión es insuficiente, es imperioso atender también a la dimensión de competitividad; y la descentralización sólo implica partidos más competitivos en su organización interna si esta no responde meramente a un criterio formal de distribución territorial del poder y si los mismos están institucionalizados conforme a principios democráticos. Ambas se pondrán a prueba a partir del armado de listas para las elecciones 2011, analizando diferencias en acción y estrategia de los partidos en diferentes distritos dependiendo de los cargos en juego y del nivel de gobierno, y se compararán con aquel de la elección precedente.Studying parties as organizations, «enlighten inside» is an unfinished challenge in Latin America. It is pretended to contribute analysing candidate selection procedures in Argentina, a case which demonstrates that are not organizational decentralization neither more inclusion in selectorates the reasons for more competitive candidate selection procedures. We present two hypotheses: thinking democratization of candidate selection as inclusiveness is not enough, it is compulsory to consider the competition dimension; and decentralization implies more competitive parties only if their internal organization does not correspond directly to a formal territorial distribution of power and if they are institutionalized according to democratic principles. Both will be tested regarding lists

Seguidamente, de una manera detallada analiza el régimen jurídico que rodea al crimen de agresión, su naturaleza jurídica, su concordancia con los principios de legalidad y complementariedad, el tipo objetivo descrito, el umbral de gravedad y antijuridicidad del acto de agresión como fundamento de la responsabilidad penal individual, el elemento subjetivo o mens rea del crimen, la figura de la tentativa, también los mecanismos de activación de la jurisdicción de la CPI. Complementariamente, este trabajo analiza las implicaciones que tiene el consenso alcanzado en Kampala a través de la Resolución RC/Res. 6, instrumento que representa un avance significativo para el crimen de agresión en el derecho internacional aunque ha sido objeto de diversas críticas. Partiendo de este escenario, el autor toma posición con la finalidad de encontrar una aplicación correcta de la norma en el ordenamiento jurídico colombiano.

Algunas regulaciones, guías disciplinarias y los exámenes estandarizados, promueven la segregación de ciertos grupos y el mantenimiento del estatus de otros. En este sentido, está en manos de los docentes la promoción de un modelo divergente que, a pesar de los lineamientos establecidos, estimule la igualdad y motive la inserción de todos los estudiantes al sistema social y productivo del país.

    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.

Debido a la imposibilidad de clasificarlo taxonómicamente en los géneros actuales, este aislamiento se ha denominado temporalmente como CENICAFE 9501. Dado su potencial como biocontrolador, se propuso identificar genes candidatos involucrados en el proceso de patogenicidad de huevos de Meloidogyne. Con este fin se construyeron librerías diferenciales mediante el método de hibridación sustractiva. La secuenciación de 188 clones obtenidos permitió identificar 80 unigenes, de los cuales el mayor porcentaje correspondió a secuencias sin homología (32%, seguidas por genes candidatos a funciones de patogénesis (22%, transporte celular (17%, síntesis de proteínas (11% y en menor proporción aquellos involucrados con transcripción y metabolismo primario (18%. Dentro de aquellos genes que contienen marcos de lectura con homología a proteínas que intervienen en la patogenicidad se encuentran una peptidasa, un receptor para sitios de ubiquitinación, una deubiquinasa, una ubiquinona oxidoreductasa, proteína relacionada con la degradación de pared celular, glicosil hidrolasa e hidroxilasa de ácidos grasos, asi como una serin proteasa.

    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 El trabajo autónomo tiene una notable implantación en España y cumple una relativamente amplia funcionalidad en nuestro sistema económico y social. En el conjunto del tejido empresarial, es absolutamente hegemónica la figura del autónomo que no dispone de asalariados a su servicio, junto con el que emplea hasta dos trabajadores por cuenta ajena. Antes de la aprobación parlamentaria de la Ley 20/2007, su regulación resultaba muy fragmentaria, deficiente y obsoleta, sin atender a las profundas transformaciones que se han sucedido tras la llegada del posfordismo a este sector. Con la entrada en vigor de dicha norma, España dispone de una ley-marco, pionera en la Unión Europea y seguramente en el mundo, que establece un régimen jurídico mínimo, común e inderogable para todos los autónomos que producen en nuestro país. Este estudio, fundamentalmente jurídico, no se centra en el análisis de la citada disposición – bautizada como Estatuto del Trabajo Autónomo -, sino en su posterior desarrollo desde su aprobación el 11 julio del 2007 hasta finales del año 2008; sin embargo, a la vista de que ese proceso ha venido a coincidir con una profunda crisis económica, la indagación se complementa con un apunte crítico sobre las principales medidas de choque adoptadas por los poderes públicos para afrontar el impacto de la recesión sobre los trabajadores autónomos, para cerrarse con una reflexión sobre las implicaciones estructurales y desafíos que supone la vigencia dicho Estatuto tanto en España como en el seno de la Unión Europea./The autonomous work has a notable implantation in Spain and fulfills a relatively wide functionality in our economic and social system.

    Full Text Available Es cuestionable si el análisis del discurso practicado en humanidades está epistemológicamente basado en una teoría y si esa teoría es la teoría de la comunicación. Después de una revisión de las ampliaciones epistemológicas de la teoría matemática de Sahnnon y su aplicación a las humanidades, y tras mostrar la dependencia del análisis de contenido y el análisis estructural-semiótico sobre la teoría del comportamiento y la teoría del lenguaje, respectivamente, se discuten los requerimientos epistemológicos para usar la teoría del análisis como el método natural de teoría de la comunicación. A la vista de esos requerimientos, la comunicación es considerada como una serie de interacciones en las cuales el procedimiento es el intercambio de información, lo que, a su vez, conduce a referirnos al modelo de Shanon sobre la dialéctica de la acción-comunicación en la interacción social.

    Full Text Available El avance del conocimiento médico y de los recursos tecnológicos ha permitido enfrentar con éxito muchas de las condiciones patológicas que afectan a la mujer embarazada y a su hijo en gestación. Aparecen sin embargo, el riesgo de no otorgar al embrión o feto el estatuto de paciente que merece por su condición de ser personal. Existen situaciones clínicas que conllevan la alternativa de interrumpir o no un embarazo en etapas con inciertas posibilidades de sobrevida para el embrión o feto. Muchas de ellas se dan en situaciones donde es perfectamente posible mantener el embarazo, asegurando un buen desenlace para la madre y su hijo, y otras donde la gravedad de la patología arriesga tanto la vida de la madre como la de su hijo en gestación. Un médico obstetra que considera como pacientes a la madre y a su hijo comprende que la interrupción del embarazo en la primera situación constituye un aborto del llamado terapéutico y por lo tanto la muerte del feto es directamente buscada. En la segunda situación, de producirse una muerte, ésta ocurre al intentar el médico salvar a sus dos pacientes. Acción no sólo lícita sino obligatoria para el médico.

    ção das respostas imune humoral e celular por meio de vacinação em camundongos BALB/c. O candidato vacinal foi submetido a análises in vivo, determinando a capacidade de induzir resposta imune específica em camundongos. O DNA de um isolado brasileiro de PCV2 foi extraído e o gene que codifica para a proteína do capsídeo foi amplificado por PCR e inserido num plasmídeo de expressão. Grupos de camundongos BALB/c foram inoculados por via intramuscular e intradérmica a cada 15 dias, com 100µg e 50µg da construção vacinal, respectivamente. Outro grupo foi inoculado com 100µg do plasmídeo original, correspondente ao grupo controle. A soroconversão e a resposta celular dos grupos de camundongos BALB/c vacinados foram comparados como parâmetros de avaliação vacinal. A soroconversão foi avaliada por um teste de ELISA. Após 3 imunizações, as células esplênicas dos animais imunizados foram utilizadas nos ensaios de linfoproliferação. A soroconversão para o PCV2 foi detectada por ELISA nos animais inoculados com a construção vacinal quando comparados com o grupo controle. Nos ensaios de linfoproliferação foi observada uma grande proliferação celular nos animais inoculados comparados ao grupo controle. Portanto, o candidato vacinal demonstrou ser capaz de induzir tanto uma resposta humoral e celular nos camundongos inoculados.

    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)

  13. Caracterización mecánica y microestructural de aceros de baja activación candidatos como primera pared en los reactores de fusión por confinamiento magnético

    Full Text Available Currently, the design development of fusion reactors and the possible materials to use in them are being studied in parallel. One of the most critical problems in this research is the structural material selection for the first wall and blanket. The aim of the present work is to study three low activation alloys designed in Germany in which niobium has been substituted by tantalum or cerium. The mechanical results show that the alloys containing cerium are in the same order of the low activation materials known to date, but the tantalum doped alloy produces TaC3 precipitation that destabilizes the matrix and provokes large microstructural changes. This causes a decrease of the mechanical properties at about 600 °C. This fact makes this alloy unsuitable for the first wall on fusion reactors, because the working temperature is near 550 °C.

    Actualmente, se está estudiando de forma paralela al desarrollo del diseño de los reactores de fusión los posibles materiales a emplear en estos. Una de las cuestiones más críticas en esta investigación es la selección del material estructural a emplear como primera pared y envoltura. En el presente trabajo se estudian tres aleaciones de diseño alemán de baja activación, en las que se ha sustituido el niobio por tantalio o por cerio. Los resultados mecánicos muestran que las aleaciones, en las que se ha añadido cerio de forma controlada, están en la línea de las de baja activación existentes hasta ahora, pero la adición de tantalio presenta problemas al provocar una precipitación primaria y masiva de carburos TaC3 que desestabiliza la matriz y origina cambios microestructurales muy acusados. Así, ocurre un descenso en las propiedades mecánicas en torno a los 600 °C, que la incapacita para la aplicación como primera pared, ya que la temperatura de trabajo de ésta se halla en torno a los 550 °C.

    Full Text Available En la historia contemporánea de Colombia, la república conservadora (1885-1930, vista en una perspectiva de larga duración, es fundamental para explicar el retardo en la irrupción de la modernidad en nuestro país, en razón de la consolidación durante medio siglo de un poder autocrático, controlado por el partido conservador y la Iglesia católica colombiana, a nombre de una ideología hispanista y confesional. Es en este período cuando se consolida en Colombia el poder cultural y simbólica del clero y la intolerancia política respecto al pensamiento de las luces y del socialismo. Así mismo, en la última fase de la hegemonía conservadora, durante los años 1920, se hizo ostensible el desfase entre, de un lado, la modernización económica y la industrialización y, de otro lado, la ausencia de modernidad social, cultural y política.

    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

    This manual has been prepared to help establish a consistent baseline of management practices across all ALS projects. It describes the initial process of planning a project, with a specific focus on the production of a formal project plan. We feel that the primary weakness in ALS project management efforts to date stems from a failure to appreciate the importance of ''up-front'' project planning. In this document, we present a guide (with examples) to preparing the documents necessary to properly plan, monitor, and control a project's activities. While following the manual will certainly not guarantee good project management, failure to address the issues we raise will dramatically reduce the chance of success. Here we define success as meeting the technical goals on schedule and within the prescribed budget.

Religion as a tool to differentiate between subjects is linked with power and dominance and, thus,with ideas about the constructed identities of “the other”. With this respects, religion functions as a code to define in- andexclusions and mark “the other”, e.g. “the Muslim” in predominantly Christian societies in Europe. Critical theories on racismenable to recognize, describe and define these practices and their effects. They can provide a useful tool to question and challengeintercultural and interreligious educational approaches which potentially reproduce and, thus, strengthen cultural/religiousdifferentiations. DEUTSCH: Die Differenz- und Heterogenitätskategorie Religion hat sich in den letzten Jahren im europäischen und auch deutschsprachigenDiskursraum zu einer medial, wissenschaftlich und politisch wirkmächtigen Kategorie entwickelt. Dabei zeigt sich Religion sowohlals soziale Unterscheidungspraxis (auch in pädagogischen Arrangements, als auch als Mittel zur Identifikation und Charakterisierungbestimmter Gruppen und Individuen als religiöse Subjekte. Religion stellt in diesem Zusammenhang einen Zugehörigkeitscodedar, mit dem Personen als natio-ethno-kulturell Andere markiert werden, wie die Markierung von MuslimInnen durchAngehörige der mehrheitlich christlichen Dominanzgesellschaft zeigt.

Se plan- tea, en este horizonte, que las miradas hermenéutica y crítica, al permitirles a las ciencias sociales tomar dis- tancia del modelo positivista de ciencia, han abierto un espacio fecundo para pensar la pedagogía como un campo de producción de conocimiento que pue- de ser agenciado por los docentes mismos. Es decir, que la investigación pedagógica —a diferencia de la investigación que toma como objeto a la educación para producir conocimiento sobre este campo y que se realiza desde miradas teóricas que no están ancladas en el trabajo educativo mismo— tiene consistencia y legitimidad en la medida en que construye su objeto en una vinculación profunda con la propia práctica. En este contexto, el artículo aborda, en primer lugar, los enfoques hermenéutico y crítico como marcos episte- mológicos de la investigación pedagógica y, en segun- do lugar, busca establecer la diferencia existente entre investigación educativa e investigación pedagógica.AbstractThis article examines the issue of scientif- ic research within the framework of the hermeneutic and critical epistemological approaches. These two approaches, by allowing social sciences to take distance from the positivist model, have opened a fertile new space to reconsider edu- cation as a knowledge production field that can be determined by the teachers themselves. Unlike research which focus- es on education to produce knowledge on this field and that is constructed from theoretical perspectives that are not an- chored in teaching, teacher research can reach the same consistency and legiti- macy by developing its object of study in its deep relation with the practice it- self.

    This study aims to identify the criteria used by advisors in the decision-making on whether to accept a candidate for mentoring in a postgraduate strictu sensu program and examines possible relationships between this decision and their scientific production and mentees evasion. In order to meet these goals one seeks to identify and analyze the selection criteria of candidates for the master's and doctorate programs at an institution; in this case, the Energy and Nuclear Research Institute - IPEN. More specifically, one seeks to study similarities and differences between those criteria among the advisors; find out whether there is a correlation between the selection criteria and the advisors characteristics (Profile); identify the selection process used by advisors and point out which are the motivations that lead to evasion according to their point of view. To meet these challenges, as the starting point of the research, a conceptual model was designed in order to form the basis for the preparation of the script for the interviews with open-ended questions as to identify the selection criteria used by a small group of advisors with a predefined profile. From that point, based on the responses obtained in interviews, the survey was expanded to all advisors working in the IPEN Postgraduate program by implementing an online survey using Google Docs app for data collection. These data were then analyzed and reorganized according to an operational model of research that would guide the analysis by structural equation modeling (SEM) by means of the SmartPLS software, in order to identify the presence or absence of correlation between the criteria adopted by the advisors and their academic production and the evasion of their mentees, for that one relied on studies in: Bazerman and Moore (2010); Cohen (1988); Hair Jr. et al (2009); Hansmann and Ringle (2004); Martins (1997); Ringle, C.; Silva and Bido (2014); Sousa (2007); Sousa and Yu (2014); Torres (2014); Yu (2011

Se pretende demostrar que el cargo político más importante de la República Islámica lo ostentará un personaje que actúe a favor de los intereses de los Pāsdārān y no a favor del principio del “más docto” que, constitucionalmente, es el prioritario y más deseable para tener el cargo. Los candidatos de los Pāsdārān deberán competir con los candidatos provenientes de otros centros de poder importantes en Irán tales como la Asamblea de Expertos o las redes informales del propio ‘Alī Jamenehēī, actores que, con sus propias fichas, intentarán imponer a aquel Ȃȳatollah que mejor se adecúe a sus intereses en la coyuntura actual iraní. This paper discusses the succession of ‘Alī Khamenei as a Supreme Leader in Iran. It shows that the most important political Office of the Islamic Republic will be held by people acting in favor of the interests of the Pāsdārān rather than supporters of "the most learned" principle which, legally, is the most desirable requirement to have the office. So, Pāsdārān´s candidates will have to compete with those who come from other centers of power in Iran such as rūḥāniȳāt, and the informal networks of 'Alī Jamenehēī, actors who, with their own means, will try to impose one Ȃȳatollah that responds to their political and economical interests in the current context of the Iranian politics.

However, we will approach this study from the legal point of view, especially to that referred to as the Proper Process. To do this, the budgets, the solution given by the Most Excellent Supreme Court, and its consequences will be analyzed. Furthermore, the given solution will be criticized from the point of view of the legal guarantees of the accused contained in the new penal process and what is contained in the Constitution and in the American Convention of Human Rights. In conclusion, we will argue in favor of a final and harmonious interpretation of the Constitution and the international agreement of human rights.

    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.

All participants answered the questionnaire regarding the sociodemographic characterisitcs. Serum samples were tested for IgG antibodies to HEV (anti-HEV by an enzyme linked immunoassay (ELISA. All serum samples positive for anti-HEV IgG and 237 serum samples negative for anti-HEV were also assayed for IgG anti-HAV antibodies by ELISA. Anti-HEV IgG was confirmed in 23/996 samples, resulting in a seroprevalence of 2.3% for HEV infection, similar to previous results obtained in developed countries. No significant association was found between the presence of anti-HEV IgG antibodies and the sociodemographic variables including gender, age, educational level, rural or urban areas, source of water, and sewer system (p > 0.05. Also, no association with seropositivity for anti-HAV IgG antibodies was observed (p > 0.05. Although this study revealed a low seroprevalence of HEV infection in the population evaluated, the results showed that this virus is circulating among the population from Londrina, South Brazil, and point out the need of further studies to define the clinical and epidemiological importance of HEV infection and to identify additional risk factors involved in the epidemiology and pathogenesis of this infection in this population.Os objetivos do estudo foram determinar a soroprevalência da infecção pelo vírus da hepatite E (VHE em candidatos a doadores de sangue voluntários do Hemocentro Regional de Londrina, Paraná, e avaliar se essa soroprevalência está associada com vari

The revelations also include the traditions of the Prophet that are authentic (shahih and good (hasan in quality. Both the Quran and maqbulah hadiths are accepted by Muslims on the basis of faith. 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. The findings of the study stated that the meaning of the word Rabb includes: creating, nurturing, maintaining, teaching, educating, and organizing. Thus, in an academic term, the word Rabb implies a manager or leader. Meanwhile, in the concept of comprehensive manager it contains at least 14 nomenclature denotations: planning, responsibility, organization, coordination, system of employee payroll, learning, resources, humanity, principle of making it easier for the manager to the employee, motivated to achieve optimal performance, preventing unproductivity, education participation, institutional costs, monitoring, and evaluation system.

    A pesquisa sobre remanescentes de aglomerados abertos tem despertado grande interesse. Seguindo esta tendência encontramos estudos teóricos e observacionais. Os primeiros baseiam-se em simulações numéricas buscando determinar fração de binárias e distâncias galatocêntricas, tempo de vida e conteúdo estelar. Estes estão relacionados à função inicial de massa e densidade de estrelas, ou seja, se ricos ou pobremente povoados, compactos ou esparsos. No caso observacional procuram-se identificar os remanescentes considerando-se que trazem estas assinaturas de seus percursores. No presente estudo empregamos espectroscopia para analisar oito concentrações pobremente povoadas, previamente classificadas como aglomerados abertos, sendo sete compactas e uma esparsa. As observações foram obtidas através do telescópio de 2,15 m do CASLEO em San Juan, Argentina, em turnos entre 2001 e 2003. Utilizamos uma câmara CCD contendo um chip Tektronics de 1024X1024 pixeis aliado a um espectrógrafo REOSC. O domínio espectral vai de 3700 a 7000 Å. As reduções foram realizadas no Observatório Astronômico de Córdoba (Argentina) usando pacotes IRAF padrões. Determinamos idades, avermelhamentos e tipos espectrais através de comparações com biblioteca de estrelas e de aglomerados. Em alguns casos nossos espectros estavam dominados por estrelas individuais às quais determinamos seus tipos espectrais. Aos oito objetos adicionamos mais cinco da literatura recente analisados via espectro ou diagrama cor-magnitude. O histograma resultante contém idades típicas entre 0.5 e 3 Ganos. Considerando que predominantemente estes objetos encontram-se na vizinhança solar e, portanto, não cruzaram muitas vezes o plano Galático esperamos que a diferença no tempo necessário para dissolução destes prováveis remanescentes seja em função de diferentes massas iniciais.

    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

    The half-life of 26 Al has been redetermined because of suggestions of an error in the accepted value based on its use in calculating 21 Ne production rates from cosmic rays in meteorites. Two solutions of 26 Al were analyzed for the specific radioactivity and mass spectrometric determination of the 26 Al concentration. The half-life obtained for 26 Al was 7.05 x 10 5 years +- 3.7% at the two sigma level. This is identical to the accepted value of 7.16 x 10 5 years and indicates that problems with the 21 Ne production rate is not due to an erroneous half-life

    1991-01-01

    Measurements on current-biased Nb/AlO x /Al/AlO x /Nb double tunnel junction devices with very thin central Al layers show a novel double hysteretic structure in the subgap region. Similar junction structures have previously exhibited very large nonequilibrium effects; the effects reported here appear close to and above the equilibrium critical temperature of Al. A model is presented in which the hysteresis is shown to arise from a transition from finite to zero voltage across one barrier on increasing current, due to the nucleation of an inhomogeneous state in the ultrathin central Al layer in which normal and superconducting states coexist. This reverse switching effect is shown to arise from the self-shunting effect of low-gap regions. Predictions of this model are shown to agree with the experimental data

    This paper presents a finite element thermal model for similar and dissimilar alloy friction stir spot welding (FSSW). The model is calibrated and validated using instrumented lap joints in Al-Al and Al-Fe automotive sheet alloys. The model successfully predicts the thermal histories for a range of process conditions. The resulting temperature histories are used to predict the growth of intermetallic phases at the interface in Al-Fe welds. Temperature predictions were used to study the evolution of hardness of a precipitation-hardened aluminum alloy during post-weld aging after FSSW.

  17. Deformation mechanisms of nanotwinned Al

    Energy Technology Data Exchange (ETDEWEB)

    Zhang, Xinghang [Texas A & M Univ., College Station, TX (United States)

    2016-11-10

    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.

    We report characteristics of CeCoIn 5 /Al/AlO x /Nb and CeCoIn 5 /Al/AlO x /Al tunnel junctions fabricated on the (0 0 1) surface of CeCoIn 5 crystal platelets. The main result of this work is the observation of a low Josephson current (as compared with that expected from the Ambegaokar-Baratoff formula), which is consistent with idea that the order parameter in the heavy-fermion superconductor CeCoIn 5 has unconventional pairing symmetry.

    Superconductor radiation detectors have the possibility of 20-30 times better energy resolution than that of a high resolution Si detector. We fabricated Nb/Al-AlOx/Al/Nb superconducting tunnel junctions with low leakage current. X rays were detected with large area junctions of 178x178 μm 2 . High energy resolution of 160 eV for 5.9 keV was obtained. We also fabricated series connected junctions which covers a rather large area of 4x4 mm 2 . α particles injected into the rear substrate were detected using nonthermal phonons induced by the radiations in the substrate.

    Full Text Available Ibn ‘Âsyûr merupakan salah seorang mufasir di zaman modern yang menghasilkan sebuah kitab tafsir yang diberi nama “al-Tahrîr wa al-Tanwîr”. Kitab tafsir ini menggunakan corak ilmiah dalam menjelaskan makna ayat al-Quran, meskipun corak tersebut masih kontroversi tentang kebolehannya. Namun, ternyata penafsiran yang dilakukan oleh Ibn ‘Âsyûr tidak mendapatkan kritikan dari ulama lainnya dalam hal penggunaan ilmu pengetahuan modern. Karena, Ibn ‘Âsyûr menggunakan corak tersebut diawali dengan pengkajian kebahasaan, selanjutnya baru dijelaskan teori-teori ilmu pengetahuan yang berkaitan dengan ayat, sehingga tidak memberi kesan pemaksaan teori ilmu pengetahuan terhadap makna ayat al-Quran.

    Full Text Available The evolusionist and functionalist approaches to religion are generally considered less sympathetic if not antipathy to religious phenomena. This is why, some western scholars propose another approach to study religion called ‘phenomenological’ approach. There have been a number of phenomenological studies of religion, but mostly not of  Islam. This article tries to fill in the gap by describing and analyzing the Islamic conception of intention (niyyah developed by al-Sayuthi and al-Ghazali. As a jurist, al-Sayuthi explores different formal rules on niyyah in Islamic jurisprudence, while al-Ghazali as a Sufi, tries to deepen the meaning of niyyah in relation to one’s sincerity to God. Apart from this difference, both conceptions of niyya indicate that as believers, Muslims always attempt to live in the sacred space and time, and make their speech and deed sacred based on the niyyah. Thus, niyya is the very basis of Muslim religious life.

    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.

  13. Dynamic Modeling of ALS Systems

    Science.gov (United States)

    Jones, Harry

    2002-01-01

    The purpose of dynamic modeling and simulation of Advanced Life Support (ALS) systems is to help design them. Static steady state systems analysis provides basic information and is necessary to guide dynamic modeling, but static analysis is not sufficient to design and compare systems. ALS systems must respond to external input variations and internal off-nominal behavior. Buffer sizing, resupply scheduling, failure response, and control system design are aspects of dynamic system design. We develop two dynamic mass flow models and use them in simulations to evaluate systems issues, optimize designs, and make system design trades. One model is of nitrogen leakage in the space station, the other is of a waste processor failure in a regenerative life support system. Most systems analyses are concerned with optimizing the cost/benefit of a system at its nominal steady-state operating point. ALS analysis must go beyond the static steady state to include dynamic system design. All life support systems exhibit behavior that varies over time. ALS systems must respond to equipment operating cycles, repair schedules, and occasional off-nominal behavior or malfunctions. Biological components, such as bioreactors, composters, and food plant growth chambers, usually have operating cycles or other complex time behavior. Buffer sizes, material stocks, and resupply rates determine dynamic system behavior and directly affect system mass and cost. Dynamic simulation is needed to avoid the extremes of costly over-design of buffers and material reserves or system failure due to insufficient buffers and lack of stored material.

    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.

  4. AlSb/InAs/AlSb quantum wells

    Kroemer, Herbert

    1990-01-01

    Researchers studied the InAs/AlSb system recently, obtaining 12nm wide quantum wells with room temperature mobilities up to 28,000 cm(exp 2)/V center dot S and low-temperature mobilities up to 325,000 cm(exp 2)/V center dot S, both at high electron sheet concentrations in the 10(exp 12)/cm(exp 2) range (corresponding to volume concentrations in the 10(exp 18)/cm(exp 2) range). These wells were not intentionally doped; the combination of high carrier concentrations and high mobilities suggest that the electrons are due to not-intentional modulation doping by an unknown donor in the AlSb barriers, presumably a stoichiometric defect, like an antisite donor. Inasmuch as not intentionally doped bulk AlSb is semi-insulating, the donor must be a deep one, being ionized only by draining into the even deeper InAs quantum well. The excellent transport properties are confirmed by other observations, like excellent quantum Hall effect data, and the successful use of the quantum wells as superconductive weak links between Nb electrodes, with unprecendentedly high critical current densities. The system is promising for future field effect transistors (FETs), but many processing problems must first be solved. Although the researchers have achieved FETs, the results so far have not been competitive with GaAs FETs.

"El movimiento cooperativo es tan viejo como la revolución industrial, y ha crecido paralelamente a ella, podría decirse como una protesta en contra del sistema capitalista industrial. Generalmente se considera que tres principios fundamentales determinan su carácter distintivo. 1-Se esfuerza por dar "servido al costo" a sus miembros antes que beneficiarse del negocio con el público en general. El servicio de un grupo organizado se considera como un medio para obtener el máximum de eficacia con mínimo de desperdicio. 2-Insiste en que los beneficios pecuniarios se distribuyan al miembro como productor, después de deducir solamente el interés del capital al tipo que compite, y los salarios y jornales de los trabajadores. 3-Mantiene el control democrático del negocio por todos los participantes en él".

    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.

    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.)

The reaction products, 29 Al, and 28 Al, beta decay to 29 Si and 28 Si, respectively, and the subsequent γ decays of 29 Si and 28 Si were measured. 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

    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).

La Corte Penal Internacional ha asumido este legado y hoy sabemos que, con o sin la complicidad de las autoridades del Estado, y a partir de la escasa jurisprudencia de la Corte Penal Internacional, estos grupos cometen crímenes de guerra como bien se estableció en la sentencia de Lubanga del 2012 y en Katanga del 2014 respectivamente. Crímenes de lesa humanidad a partir concretamente de la Decisión de Apertura de una Investigación para Kenia en 2010 donde la Sala a pesar de discrepancias adoptó la posición de que estos grupos organizados, con algún tipo de jerarquía y capaces de infringir los derechos humanos pueden ser considerados ‘organización’ en el sentido del artículo 7 del Estatuto de Roma.

    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.

    2013-01-01

    Thin copper-doped aluminum oxide (Cu-doped-AlO x ) and AlO x films of about 5 nm thick were generated by oxidizing the surfaces of Al and Al-5 wt.% Cu (Al-Cu) films in an oxygen plasma. According to X-ray photoelectron spectroscopy analyses, these two oxide films were found to be deficient in oxygen and had gradient concentrations of Al and O. The oxide films were employed as resistor layers sandwiched between an Al top electrode and an Al or Al-Cu bottom electrode to form resistive memory devices. The devices demonstrated unipolar resistance switching between high resistance state and low resistance state (LRS), and their resistance ratios measured at + 0.2 V were around 10 5 . Furthermore, their current–voltage characteristics showed ohmic conduction with the resistance increasing with temperature, in LRS. Conductive filaments were thought to form inside the AlO x film and the Cu-doped AlO x film, causing resistive switching. The resistive memory device using the AlO x film had unstable switching behaviors during cyclic testing, whereas the device using the Cu-doped AlO x film demonstrated stable resistance switching during 100 cycles of testing. The presence of the Cu ingredient in the AlO x film is likely to facilitate the formation and rupture of conductive filaments and induced stable resistance switching. - Highlights: • AlO x layers are formed by plasma oxidation for resistance memory device (RRAM). • Al/AlO x /Al and Al/AlO x -CuO x /Al-Cu exhibit unipolar resistance switching. • Cu doping assists formation of the filaments of mixed Al and Cu in AlO x . • Cu doping improves endurance and retention of the AlO x -based RRAM

    Full Text Available Very fine and sinterable ceramic powders (100-600 nm in the system Al2O3-TiO2-SiO2 were obtained by the method of cohydrolisis from organo-metallic precursors. Isostatically pressed powder compacts could be densified to a relative high density (~ 92 % th. density at relative low temperatures (1320-1380ºC. The technical coefficient of thermal expansion was measured by dilatometry. The value obtained (8.8 10-6 1/ºC corresponds closely to that of Ti, opening the possibility to use Al2O3-TiO2-SiO2 ceramics to fabricate metal/ceramic composite implants. The measured mechanical properties of dense sintered Al2O3-TiO2-SiO2 material: Young´s modulus, flexure strength and compression strength, are higher than those of pure TiO2. Highly porous Al2O3-TiO2-SiO2 ceramics (P~ 65% were obtained by the method of evaporation of hydrogen peroxide. These materials exhibited interconnected porosity and their properties, particularly the Young´s modulus, resulted very similar to those of bone, which is an important pre-requisite for the design of quirurgical implants.Se han obtenido polvos cerámicos muy finos (100- 600 nm y de alta sinterabilidad, en el sistema Al2O3-TiO2-SiO2, por el método de co-hidrólisis controlada a partir de precursores organo-metálicos. Los compactos fabricados a partir del polvo de cohidrólisis calcinado fueron sinterizados en el rango de temperaturas 1320-1380 ºC, obteniéndose densidades elevadas (~ 92% D.T..

    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

  12. Opportunity's 'Rub al Khali' Panorama

    2005-01-01

    [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

    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. The Al 3 Re phase was found to have a monoclinic structure with a = 0.5180(4) nm, b = 3.97641(9) nm, c = 0.4955(3) nm and β = 99.55(7) o

    Sich kontinuierlich verändernde Rahmenbedingungen, wie beispielsweise eine steigende Variantenvielfalt, verkürzte Produktlebenszyklen sowie Kundenforderungen nach höherer Qualität, kürzeren Lieferzeiten und geringeren Kosten, fordern von produzierenden Unternehmen eine stetige Anpassung der Prozesse, der Organisation und der Strukturen. Seit den 90er Jahren versuchen immer mehr deutsche Unternehmen diesen veränderten Anforderungen mit der Einführung eines Ganzheitlichen Produktionssystems (GPS) zu begegnen. Ganzheitliche Produktionssysteme sind dabei in ihren Grundlagen an das Toyota Produktionssystem angelehnt, vereinigen aber auch weitere Methoden zu einem unternehmensspezifischen Regelwerk. Im Rahmen des langfristigen Trends zu unternehmensindividuellen Produktionssystemen wird sowohl in der Industrie als auch in der Forschung intensiv über das Toyota Produktionssystem, Lean Production, Lean Management und Ganzheitliche Produktionssysteme diskutiert, werden Konzepte zu Implementierung und Betrieb erstellt und die Wirtschaftlichkeit untersucht.

    Full Text Available Man könnte sagen, dass Aristoteles so etwas wie eine traditionelle und dominierende Auffassung der Entscheidung in der westlichen Philosophie gründet. Das Ziel dieses Aufsatzes ist es, diese Auffassung von Aristoteles zu entwerfen, einige ihrer wichtigsten Probleme anzusprechen, und sie damit zu kontrastieren, was ich Jacques Derridas häretische „Konzeptualisierung“ der Entscheidung nennen würde. Es wird gezeigt, dass diese häretische Thematisierung von Derrida nicht nur und einfach mit dem traditionellen aristotelischen Begriff bricht, sondern vielmehr auch zu Recht einige seiner wichtigsten Züge auf solcher Weise schärft, dass von diesem radikalisierten Standpunkt die Behandlung von Aristoteles als die Annullierung der Entscheidung zum Vorschein kommt. Es wird zudem impliziert, wie Derridas häretische Auffassung die Erneuerung der Ethik und Politik mit sich bringt.

    Aluminum-substituted magnetite (Al-magnetite) reduced from Al-substituted hematite or goethite (Al-hematite or Al-goethite) is an environmentally important constituent of magnetically enhanced soils. In order to characterize the magnetic properties of Al-magnetite, two series of Al-magnetite samples were synthesized through reduction of Al-hematite by a mixed gas (80% CO2 and 20% CO) at 395°C for 72 h in a quartz tube furnace. Al-magnetite samples inherited the morphology of their parent Al-hematite samples, but only those transformed from Al-hematite synthesized at low temperature possessed surficial micropores, which originated from the release of structural water during heating. Surface micropores could thus serve as a practical fingerprint of fire or other high-temperature mineralogical alteration processes in natural environments, e.g., shear friction in seismic zones. In addition, Al substitution greatly affects the magnetic properties of Al-magnetite. For example, coercivity (Bc) increases with increasing Al content and then decreases slightly, while the saturation magnetization (Ms), Curie temperature (Tc), and Verwey transition temperature (Tv) all decrease with increasing Al content due to crystal defect formation and dilution of magnetic ions caused by Al incorporation. Moreover, different trends in the correlation between Tc and Bc can be used to discriminate titanomagnetite from Al-magnetite, which is likely to be important in environmental and paleomagnetic studies, particularly in soil.

    Fe{sub 3}Al-Al{sub 2}O{sub 3} nanocomposite powder was successfully synthesized by mechanochemical route starting from Fe{sub 2}O{sub 3} and Al powder mixture. The resulting nanocomposite powder was consolidated at 1400 deg. C for 1 h. The phase transformation and microstructural characterization during mechanochemical reaction and sintering were investigated by X-ray diffractometry (XRD) and scanning electron microscopy (SEM). The results showed that during ball milling the Fe{sub 2}O{sub 3}-Al combustion reaction directly produces the Fe{sub 3}Al-Al{sub 2}O{sub 3} nanocomposite. The consolidated Fe{sub 3}Al-Al{sub 2}O{sub 3} part had an ultrafine uniform structure without 'core-rim' feature consisting of an interconnected network of Fe{sub 3}Al and Al{sub 2}O{sub 3} phases.

    Full Text Available A method to engineer the peak-to-valley ratio (PVR by design of the epitaxial layers is presented. The impact of Al content on PVR of InAs/AlSb/Al(xGa(1−xSb tunnelling diode is studied. A simplified analytical model is used to explain the PVRs dependence on Al content. It was found that PVR reaches its maximum when Al content x is zero with a quantised InAs layer. The peak positions appeared in the negative differential region are effectively controlled by the applied gate bias. A PVR ratio as high as 7.1 was achieved, which is beneficial for a wide range of circuit applications. Adjusting Al content provides a new way to engineer the PVR as opposed to the conventional way of being optimised by varying barrier thicknesses or doping levels.

    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

    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.

    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

Dada la discrecionalidad en su celebración, el contrato de prestación de servicios también es el vehículo empleado para oficializar y legitimar el incumplimiento de los mandatos constitucionales y legales que imponen la carrera administrativa para el ingreso y permanencia en la función pública. Además con la desfiguración del concepto legal del contrato de prestación de servicios se logra eludir el reconocimiento y pago de prestaciones sociales, lo cual se traduce en desmejoramiento de las condiciones económicas de los contratistas. En síntesis el prestación de servicios de manera velada desconoce el ordenamiento jurídico superior, no obstante la posición de censura adoptada en un comienzo por las altas instancias judiciales. Ello, en razón a que la legislación colombiana a partir de la Constitución Política define el carácter del servidor público con los derechos y obligaciones que le son propios; de igual manera, establece en el Estatuto de la Contratación Estatal - Ley 80 de l.993- los principios rectores que deben orientar todos los procesos de contratación a cargo de las entidades oficiales. En consecuencia, ambas instituciones: la del servidor público y la del contrato estatal, pertenecen al campo de la función administrativa; están reguladas por normas de Derecho Público y más exactamente por el Derecho Administrativo. A partir de tales presupuestos es labor de la investigación, ubicar tanto la contratación estatal como la función pública bajo las directrices que impone la Carta Política en un Estado social de derecho, con todas las consecuencias que tal consagración conlleva.

    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

    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.

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.

    Promising creep strengths were found for a directionally solidified NiAl-NiAlTa alloy when compared to other NiAl based intermetallics. The directionally solidified alloy had an off-eutectic composition that resulted in microstructures consisting of NiAl dendrites surrounded by aligned eutectic regions. The room temperature toughness of the two phase alloy was similar to that of polycrystalline NiAl even with the presence of the brittle Laves phase NiAlTa. Alloying additions that may improve the room temperature toughness by producing multiphase alloys are discussed.

    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.

  20. 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.

    Full Text Available Human being equipped by God Almighty with a variety of gifts which enable them to carry a burden of duties. The gifts are power of the body, vitality and power al-qalb. Islam has made clear necessity of a proper functioning of al-qalb to think in order to develop knowledge. It will help people to carry caliphate duties on earth properly, under the guidance of al-Qur’an and al-Sunnah. One way to enhance thinking of al-qalb required by Islam is dzikir, therefore, someone will find peace of mind and feel close to God. Feeling close to God, a person’s soul will be controlled. Conversely, if a person is not functioning qalb for dzikir, so he will experience drought soul. In al-Qur’an, al-qalb may have some meanings; it refers to the context of verse that contains in it. Moreover, to present the meaning of al-qalb is not always disclosure with the word of al-qalb, but also often disclosure by using the word of al-fuad, al-lub, al-nafs and al-sadr

    Remarkable advances in our understanding of the genetic contributions to amyotrophic lateral sclerosis (ALS) have sparked discussion and debate about whether clinical genetic testing should routinely be offered to patients with ALS. A related, but distinct, question is whether presymptomatic genetic testing should be offered to family members who may be at risk for developing ALS. Existing guidelines for presymptomatic counseling and testing are mostly based on small number of individuals, clinical judgment, and experience from other neurodegenerative disorders. Over the course of the last 8 years, we have provided testing and 317 genetic counseling sessions (including predecision, pretest, posttest, and ad hoc counseling) to 161 first-degree family members participating in the Pre-Symptomatic Familial ALS Study (Pre-fALS), as well as testing and 75 posttest counseling sessions to 63 individuals with familial ALS. Based on this experience, and the real-world challenges we have had to overcome in the process, we recommend an updated set of guidelines for providing presymptomatic genetic counseling and testing to people at high genetic risk for developing ALS. These recommendations are especially timely and relevant given the growing interest in studying presymptomatic ALS. PMID:27194384

    Full Text Available Artikel ini mengulas pemikiran al-Farabi tentang konsep kenabian dalam Islam. Masalah berawal dari adanya pemikiran yang menolak konsep kenabian pada umumnya dan kenabian Nabi Muhammad SAW khususnya. Sebagaimana yang dilontarkan oleh Muhammad Ahmad ibn al-Ruwandi. Ia mengatakan bahwa nabi sebenarnya tidak diperlukan manusia karena Tuhan telah mengaruniakan akal kepada manusia tanpa terkecuali. Dengan akal ini, manusia dapat mengetahui Tuhan beserta segala nikmat Nya dan dapat pula mengetahui perbuatan baik dan buruk, menerima suruhan dan larangan-Nya. Dengan demikian, nabi dengan segala fungsinya tidak diperlukan lagi. Bahkan, kitab suci pun tidak berguna untuk dibaca. Lebih berguna membaca buku filsafat Epicurus, Plato, Aristoteles, dan buku astronomi, logika, serta obat-obatan. Hal ini tentunya bertolak belakang dengan yang diajarkan dalam Islam. Beriman kepada nabi nabi merupakan hal inti dalam ajaran agama ini. Atas dasar itu al-Farabi bereaksi keras. Baginya, pandangan Ibn al-Ruwandi di atas tidak dapat dibenarkan, khususnya dari sisi akidah Islam. Sebagai al-Mu‘allim al-Tsani (Guru Kedua, karena prestasinya dalam menjelaskan dan mengulas-ulang filsafat Aristoteles, al-Farabi mengkritik secara sistematik pandangan menyimpang al-Ruwandi di atas.

    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

    The thin tunneling barrier in a Nb/AlO x -Al/Nb Josephson junction was characterized by anodization profiles. Our studies focused on Nb/AlO x and Al/Nb interfaces in Nb/AlO x -Al/Nb junctions made by varying certain process parameters. The interface quality was checked by the anodization profiles and was greatly affected by film thickness, layer sequence, annealing treatment, and the existence of a thin oxide. By comparing the profiles with the junction characteristics measured at 4.2 K, we confirmed that the interface sharpness in the profiles is related to the junction quality. The anodization profile is a useful tool to diagnose the tunneling barrier interfaces in Nb/AlO x -Al/Nb Josephson junctions, especially at room temperature during fabrication

    This paper reports on a study of microstructure of Nb/AlO x ---Al/Nb Josephson junctions by cross-sectional transmission electron microscopy (TEM) which yielded much information regarding the unction barrier region. Both thick Nb and several-nm Al form polycrystalline films with columnar structures. Nb is oriented to the (110) plane, and Al is (111). The 200-nm lower Nb has a wavy surface with ∼5 nm smoothness, but its surface is planarized by several-nm Al deposited on it. Thus AlO x with a smoothness under 1 nm can be formed on Al. The upper Nb has a good crystalline structure even just above the AlO x barrier

First, al-nafs is a substance that distinguishes human qualities with other creatures. Second, al-nafs is the cause of man to be creative and dynamic, through the process of inspiration and contemplation. Therefore, the level of quality of the nafs is different. In the literature of Sufism, the nafs can be transformed from a trend that is closest to the bad action to the level of closeness to the divine tenderness. Third, the nafs is the impulse of anger and lust, and urge all reprehensible nature, and immoral in mind. Sufi Sunni, al-Ghazālī calls nafs as the center of the potential upset, and the base of the despicable nature. Therefore, al-nafs need to be purified so that the properties of self perverted man disappeared. Road purification al-nafs is riyāḍah and mujahadah who constantly so al-nafs is ultimately up to the level of the nafs al-muṭmainnah. Abstrak: Artikel ini akan mengelaborasi tentang al-nafs (jiwa yang merupakan bagian yang penting dari hakikat manusia. Para sufi membagi pengertian al-nafs ini dalam tiga pengertian.

Kedua, al-nafs merupakan penyebab manusia menjadi kreatif dan dinamik, melalui proses inspirasi dan tafakur. Karena itu, tingkatan kualitas nafs orang berbeda-beda. Dalam literatur tasawuf, nafs ini dapat ditransformasikan dari kecenderungan yang paling dekat pada tindakan buruk sampai ke tingkat kedekatan pada kelembutan ilahi. Ketiga, nafs ialah dorongan amarah dan syahwat, serta dorongan segala sifat tercela, dan maksiat dalam batin. Seorang sufi Sunni, al-Ghazālī menyebut nafs sebagai pusat potensi marah, dan pangkal dari sifat tercela. Karena itu, al-nafs ini perlu disucikan agar sifat-sifat tercela itu lenyap dari diri manusia. Jalan penyucian al

    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.

    Full Text Available O objetivo deste artigo é descrever problematizando o cotidiano da construção de uma pesquisa que, ela mesma, busca entender como se produz, a partir da implantação de políticas públicas, ações sobre um cotidiano naturalizado de discriminações de caráter homofóbico e sexista nas escolas do Brasil e da França. Além de apresentar informações e hipóteses que emergem do trabalho de campo, a intenção do texto é apresentar os desafios de uma pesquisa que mergulha no cotidiano de culturas e contextos socio-econômicos distintos. A análise da utilização da ferramenta da comparação, pensada como efeito de distorção da imagem no espelho e colocação em suspenso de formas pré-construídas de compreensão do vivido, indica que uma intervenção analítica desta ordem permite, de forma distinta da pretensão de generalização pópria a um exercício de comparação de base positivista, a desnaturalização de formas de pesquisar e de compreender as problemáticas sobre as quais nos debruçamos.The goal of this article is to describe and problematize the quotidian of producing a research, which, in itself, seeks to understand how naturalized homophobic and sexist discriminatory actions are produced in the quotidian of schools in Brazil and France, based on the implementation of public policies. Besides presenting information and hypotheses derived from fieldwork, the intention of this text is to present the challenges of a research that immerses into the quotidian of different socioeconomic and cultural contexts. The analysis of using the comparative tool, considered as having a distortion effect of an image in the mirror and suspension effect of pre-constructed forms of comprehension of what is experienced, indicates that this order of analytic intervention allows to denaturalize research practices and the understanding of problems, distinctively from positivist comparison exercises that intend to generalize.

    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.

  12. Alanes formation on the Al(111) surface

    Alane clusters (AlxHy) are believed to be the ubiquitous intermediates in hydrogen storage reactions for a wide variety of alanates (LiAlH4, NaAlH4) currently considered for hydrogen storage. The formation and behavior of alanes at surfaces appear to control and limit the efficiency of hydrogen storage. In particular, hydrogen adsorption on the Al(111) surface leads to the coexistence of several adsorbed species, the concentration of which is affected by the step density, the surface coverage and the temperature. We combine density functional theory (DFT) and surface infra-red (IR) absorption spectroscopy to uncover the mechanisms for alane formation on Al(111) surfaces. At low coverage, DFT predicts a two-fold bridge site adsorption for atomic hydrogen, consistent with previous Electron Energy Loss Spectroscopy measurements. At higher coverage, the formation of small chemisorbed AlH3 occurs at the step edges. With increasing coverage AlH3 is extracted from the step edge and becomes highly mobile on the terraces in a weakly bound state. This mobility is the key factor leading to the growth of larger alanes through AlH3 oligomerization. For these large alanes, previous Thermal Programmed Desorption studies are discussed and compared to the thermal stability observed in IR.

    In many parts of the world, arsenic from geogenic and anthropogenic sources deteriorates the quality of drinking water resources. Effective methods of arsenic removal include adsorption and coagulation with iron- and aluminum-based materials, of which polyaluminum chloride is widely employed as coagulant in water treatment due to its low cost and high efficiency. We compared the arsenic uptake capacity and the arsenic bonding sites of different Al-based sorbents, including Al nanoclusters, polyaluminum chloride, polyaluminum granulate, and gibbsite. Extended X-ray absorption fine structure (EXAFS) spectroscopy revealed that As(V) forms bidentate-binuclear complexes in interaction with all Al-based removal agents. The octahedral configuration of nanoclusters and the distribution of sorption sites remain the same in all types of removal agents consisting of nano-scale Al oxyhydroxide particles. The obtained distances for As(V)-O and As(V)-Al agreed with previously published data and were found to be 1.69 ± 0.02 Å and 3.17-3.21 Å, respectively. Our study suggests that As(V) binds to Al nanoclusters as strongly as to Al oxide surfaces. The As sorption capacity of Al nanoclusters was found to be very similar to that of Al clusters in a polyaluminum chloride. The most efficient Al-based sorbents for arsenic removal were Al nanoclusters, followed by polyaluminum granulate. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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.' ' '

    2017-05-01

    A set of binary Pb-Al alloys with different Al contents were designed in this work. The mechanical properties and corrosion resistance of Pb-Al alloys were investigated with help of tensile test, Charpy V-notch impact test and salt spray corrosion test (SSCT). And the microstructure was observed by optical microscopy. The results showed that microstructure of all alloys were twin structure, and the twin structure was gradually refined with the increase of Al content. Al dissolved in matrix could significantly improve the tensile strength, impact energy and corrosion resistance. However, a higher content of Al would harm the mechanical properties and corrosion resistance. It may be due to the heterogeneous precipitation of Al rich phase.

    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

    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

    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.

    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.

    In this work, we present experimental data of physical properties (viscosity, surface tension, magnetic susceptibility and electroresistivity) studies for Al-R (R = Ce, Pr, Sm, Gd, Dy, Ho, Yb and Y) alloys and first intermetallic compounds from aluminum side, Al 11 R 3 (Al 3 R). All properties were measured during heating up to 2000 K and the following cooling down under helium atmosphere. The main results are: (1) the electronic characteristics of the objects are in good correlation with R positions in the periodic table, but rather lower than for pure elements. The conclusion is that through all investigated temperature range, the rare-earth elements have partly covalent but not only metallic states; (2) all the melts remain strongly microheterogeneous even at high overheatings above liquidus. The existence of associations with Al 2 R type is highly probable here. Some destruction of these associations takes place with increasing temperature above melting point at the composition of Al 2 R compound. However, the transformation into true solution state is somewhere above 1900 K. To check the idea, the thermodynamic modeling of the melts was performed. It was shown that associates with Al 2 R type are stable up to 2000 K

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

    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

    In order to reduce the leaching of pollutants and remove the Al and Zn/Al alloy from municipal solid waste incineration bottom ash (MSWIBA), an optimized alkaline pre-treatment procedure was developed in this study. The influences of alkaline conditions on the removal rate of Al and Zn/Al alloy were investigated, including [OH] - concentration, temperature, particle size, liquid/solid ratio and treatment duration. The experimental results showed that the optimized alkaline pre-treatment conditions to efficiently remove the Al and Zn/Al alloy was by using a minimum of 1.0mol/l [OH] - , at 55°C and with a minimal liquid/solid ratio of 5. The removal rate of Al and Zn/Al alloy followed an S-shape curve, in which the slow beginning stage was attributed to the protection of the oxidation layer and the quenched product around the Al and Al/Zn alloy. After 3h of the optimized alkaline pre-treatment, the leaching of Cr, Cu, Pb and Zn of the treated MSWIBA was reduced by more than 90% of that of the original MSWIBA. The alkali-silica reaction test further indicated that the expansion of concrete prepared with the pre-treated MSWIBA was significantly reduced and there was no macro-crack or spalling damage on the surface of the tested specimens.

  2. Heterogeneous nucleation of solid Al from the melt by Al 3 Ti : Molecular dynamics simulations

    2010-10-27

    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.

    Aluminum (Al) toxicity is a primary limitation to crop growth in acidic soils. Rice (Oryza sativa L.) seedlings exposed to Al show significantly inhibited root growth. To understand the precise mechanisms underlying Al toxicity, a comparative protein profile analysis of roots from two rice cultivars was conducted using 2-DE and MALDI-TOF/TOF-MS. A total of 79 Al-regulated proteins were identified, from which 54 and 45 proteins were differentially regulated in Kasalath (Al-sensitive) and Koshihikari (Al-resistant) cultivars, respectively. Gene Ontology and clustering analysis revealed an increase in relative abundance in vacuolar H(+)-ATPase, whereas structural proteins were decreased in both cultivars. Under Al toxicity, proteins involved in the antioxidative system, carbohydrate and nucleotide anabolism were increased in Koshihikari, whereas proteins participating in pathogenesis and carbohydrate catabolism were increased in Kasalath. Furthermore, the abundance of proteins involved in signal transduction, translation and transcription were different between the two cultivars. Our results suggest that destruction of the molecular structure is a major cause of cellular damage, and vacuolar sequestration of Al ions is an important Al resistant mechanism in rice. Both active oxygen scavenging systems and carbohydrate metabolism could play important roles in determining the Al tolerance among rice cultivars. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available O trabalho de Al-Qawasmi et al.², publicado em agosto de 2003 no periódico Journal of Dental Research, procurou estabelecer um gene candidato para a hereditariedade e predisposição genética nas reabsorções dentárias em Ortodontia, mas apresentou e repetiu algumas limitações metodológicas e equívocos na interpretação de seu trabalho anterior de março de 2003¹. Nas conclusões afirmam explicitamente que os achados são preliminares e sugestivos, necessitando de confirmação por meio de estudos adicionais. Os resultados são correlacionados fundamentando-se em dados de outros autores sobre síndromes ósseas associadas a reabsorções por substituição, cervicais externas e não com as reabsorções radiculares externas apicais induzidas ortodonticamente. O gene da reabsorção radicular externa apical relacionada a tratamentos ortodônticos não foi determinado e muito menos a sua natureza hereditária. Nem tampouco, a suscetibilidade à reabsorção radicular em Ortodontia foi detectada ou provada. O trabalho analisado e os demais relacionados com o mesmo tema não conseguiram comprovar suas hipóteses porque ignoram que o primeiro passo para a reabsorção radicular externa é a destruição da camada cementoblástica e isto apenas ocorre a partir da ação de fatores locais. Analisando criticamente estes trabalhos podemos afirmar que procurar o gene da reabsorção radicular e da suscetibilidade a partir de pesquisas em mediadores e células clásticas demonstra a falta de um conhecimento completo e amplo da etiopatogenia deste importante fenômeno biológico, imprescindível para o estabelecimento da premissa dos trabalhos.The study of Al-Qawasmi et al.² published in August 2003 on Journal of Dental Research, aimed to establish a candidate gene for heritability and genetic predisposition to external root resorption in orthodontic patients.

    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 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

    In the present work, the microstructure of a melt-spun Al-5 Sb alloy has been characterized using X-ray diffraction and transmission electron microscopy. The phases present in the melt-spun Al-5 Sb alloy were determined to be the equilibrium α-Al and AlSb, identical to those in the ingot-cast alloy. The microstructure of the melt-spun Al-5 Sb alloy is composed of primary AlSb phase embedded in the matrix comprising α-Al cells with intercellular nanoscale AlSb particles, different from that of the ingot-cast alloy composed of the primary AlSb phase within an α-Al/AlSb eutectic matrix. Rapid solidification has a marked effect on the morphology, size and distribution of the primary AlSb phase in the melt-spun Al-5 Sb alloy. Furthermore, some orientation relationships were determined in the melt-spun alloy

    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.

    To research the photoemission performance of a transmission-mode Al(1-x)Ga(x)N photocathode, Al0.24Ga0.76N and GaN photocathodes with the same structure were activated, their spectral responses were measured using a multi-information measurement system at room temperature, and the photocathode parameters were obtained by fitting quantum efficiency curves. The results showed that both the reflective-mode and transmission-mode spectral responses of the AlGaN photocathode were lower than those of the GaN photocathode. Compared with the GaN photocathode, the short-wavelength spectral response of the Al0.24Ga0.76N photocathode was less seriously affected by lattice defects between the buffer and emission layers. The Al atom at the AlGaN photocathode surface could affect the optimal Cs adsorption position, which mainly affects the surface electron escape probability of the photocathode.

    The effects of different aluminum species on malate dehydrogenase (MDH) activity were investigated by monitoring amperometric i-t curves for the oxidation of NADH at low overpotential using a functionalized multi-wall nanotube (MWNT) modified glass carbon electrode (GCE). The results showed that Al(III) and Al(13) can activate the enzymatic activity of MDH, and the activation reaches maximum levels as the Al(III) and Al(13) concentration increase. Our study also found that the effects of Al(III) and Al(13) on the activity of MDH depended on the pH value and aluminum speciation. Electrochemical and circular dichroism spectra methods were applied to study the effects of nano-sized aluminum compounds on biomolecules.

    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 .

    Conserved populations, such as Sardinians, displaying elevated rates of familial or sporadic ALS provide unique information on the genetics of the disease. Our aim was to describe the genetic profile of a consecutive series of ALS patients of Sardinian ancestry. All ALS patients of Sardinian ancestry, identified between 2008 and 2013 through the ITALSGEN consortium, were eligible to be included in the study. Patients and controls underwent the analysis of TARDBP, C9ORF72, SOD1, and FUS genes. Genetic mutations were identified in 155 out of 375 Sardinian ALS cases (41.3%), more commonly the p.A382T and p.G295S mutations of TARDBP, and the GGGGCC hexanucleotide repeat expansion of C9ORF72. One patient had both p.G295S and p.A382T mutation of TARDBP and eight carried both the heterozygous p.A382T mutation of TARDBP and a repeat expansion of C9ORF72. Patients carrying the p.A382T and the p.G295S mutations of TARDBP and the C9ORF72 repeat expansion shared distinct haplotypes across these loci. Patients with co-occurrence of C9ORF72 and TARDBP p.A382T missense mutation had a significantly lower age at onset and shorter survival. More than 40% of all cases on the island of Sardinia carry a mutation of an ALS-related gene, representing the highest percentage of ALS cases genetically explained outside of Scandinavia. Clinical phenotypes associated with different genetic mutations show some distinctive characteristics, but the heterogeneity between and among families carrying the same mutations implies that ALS manifestation is influenced by other genetic and non-genetic factors.

    Current-transport mechanisms were investigated in Schottky contacts on AlInN/AlN/GaN single channel (SC) and AlInN/AlN/GaN/AlN/GaN double channel (DC) heterostructures. A simple model was adapted to the current-transport mechanisms in DC heterostructure. In this model, two Schottky diodes are in series: one is a metal–semiconductor barrier layer (AIInN) Schottky diode and the other is an equivalent Schottky diode, which is due to the heterojunction between the AlN and GaN layer. Capacitance–voltage studies show the formation of a two-dimensional electron gas at the AlN/GaN interface in the SC and the first AlN/GaN interface from the substrate direction in the DC. In order to determine the current mechanisms for SC and DC heterostructures, we fit the analytical expressions given for the tunneling current to the experimental current–voltage data over a wide range of applied biases as well as at different temperatures. We observed a weak temperature dependence of the saturation current and a fairly small dependence on the temperature of the tunneling parameters in this temperature range. At both a low and medium forward-bias voltage values for Schottky contacts on AlInN/AlN/GaN/AlN/GaN DC and AlInN/AlN/GaN SC heterostructures, the data are consistent with electron tunneling to deep levels in the vicinity of mixed/screw dislocations in the temperature range of 80–420 K. - Highlights: • Current mechanisms were investigated on single and double channel heterostructures. • A model was adapted to the current mechanisms in double channel heterostructures. • We observed a weak temperature dependence of the saturation current. • And a small dependence of the tunneling parameters in this temperature range.

    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.

    Despite the excellent high temperature mechanical properties of the Ni3Al intermetallic compound, its application is still limited due to its inherently weak grain boundary. Recent research advances have demonstrated that the tensile ductility can be enhanced by controlling the grain morphology using a directional solidification. In this study, a series of directional solidification experiments were carried out to increase both the tensile ductility and the strength of Ni3Al alloys by arraying either the ductile phase of γ-Ni-rich dendrite fibers or the hard phase of β-NiAl dendrite fibers in the γ'-Ni3Al matrix. The dendrite arm spacing could be controlled by the solidification rate, and the volume fraction of the γ or β phase could be altered by the Al content, ranging from 23 at.% to 27 at.%. With an increasing Al content, the γ dendritic microstructure was transformed into the β dendrite in the γ' matrix, thereby reducing the tensile ductility by increasing the volume fraction of brittle β dendrites in the γ' matrix. With an increasing solidification rate, the dendrite arm spacing decreased and the tensile properties of Ni3Al varied in a complex manner. The microstructural evolution affecting the tensile behavior of directionally solidified Ni3Al alloy specimens with different solidification rates and Al contents is discussed.

    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.

    2014-02-01

    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.

    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)

    A novel route for the synthesis of boehmite nanospheres with a hollow core and the shell composed of highly crumpled AlOOH nanosheets by oxidizing Al nanopowder in pure water under mild processing conditions is described. The stepwise events of Al transformation into boehmite are followed by monitoring the pH in the reaction medium. A mechanism of formation of hollow AlOOH nanospheres with a well-defined shape and crystallinity is proposed which includes the hydration of the Al oxide passivation layer, local corrosion of metallic Al accompanied by hydrogen evolution, the rupture of the protective layer, the dissolution of Al from the particle interior and the deposition of AlOOH nanosheets on the outer surface. In contrast to previously reported methods of boehmite nanoparticle synthesis, the proposed method is simple, and environmentally friendly and allows the generation of hydrogen gas as a by-product. Due to their high surface area and high, slit-shaped nanoporosity, the synthesized AlOOH nanostructures hold promise for the development of more effective catalysts, adsorbents, vaccines and drug carriers.

    In the present work, the microstructural characterization of a melt-spun Al-20 Sb alloy has been carried out using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The phases present in the melt-spun Al-20 Sb alloy were determined to be α-Al and AlSb, identical to those in the ingot-cast alloy. The microstructure of the melt-spun Al-20 Sb alloy is dominantly composed of primary AlSb dendrites embedded in the α-Al matrix, different from that of the ingot-cast alloy composed of primary AlSb plates within an α-Al/AlSb eutectic matrix. In addition, some areas comprise primary AlSb particles within the α-Al matrix in the melt-spun alloy

    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.

    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.

    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

This paper aims to examine one of al-Baghawi’s skills in sanad collection which is the uluww al-isnād and nuzūl al-isnād, recorded from his two works Ma’ālim al-Tanzīl and Syarḥ al-Sunnah. The quantitative, qualitative and comparative approach has been used in this study to give an authentic description of the terms ‘uluww al-isnād, nuzūl al-isnād from al-Baghawi. Studies have found there are many examples of uluww al-Isnād and nuzūl al-isnāds contained in the patterns of al-Baghawi’s chain of narration towards the Ṣaḥīḥayn of al-Bukhari and Muslim as the mustakhrij

    The Al{}+ ion optical clock is a very promising optical frequency standard candidate due to its extremely small black-body radiation shift. It has been successfully demonstrated with the indirect cooled, quantum-logic-based spectroscopy technique. Its accuracy is limited by second-order Doppler shift, and its stability is limited by the number of ions that can be probed in quantum logic processing. We propose a direct laser cooling scheme of Al{}+ ion optical clocks where both the stability and accuracy of the clocks are greatly improved. In the proposed scheme, two Al{}+ traps are utilized. The first trap is used to trap a large number of Al{}+ ions to improve the stability of the clock laser, while the second trap is used to trap a single Al{}+ ion to provide the ultimate accuracy. Both traps are cooled with a continuous wave 167 nm laser. The expected clock laser stability can reach 9.0× {10}-17/\\sqrt{τ }. For the second trap, in addition to 167 nm laser Doppler cooling, a second stage pulsed 234 nm two-photon cooling laser is utilized to further improve the accuracy of the clock laser. The total systematic uncertainty can be reduced to about 1× {10}-18. The proposed Al{}+ ion optical clock has the potential to become the most accurate and stable optical clock.

    Al-Biruni's was of Persian descent. He was born in Horesmiya and had studied mathematics, history and medicine. Acquiring knowledge from these sciences, he wrote an outstanding work on chronology of several nations and devoted it to Ziyarit ruler Kabus. 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.

    We present characteristics of overdamped Josephson junctions consisting of Nb/AlO x /Al/ AlO x /Nb structures. The junctions were fabricated using a well-developed Nb/AlO x /Nb-junction technology and showed well-defined Josephson characteristics at 4.2 K. The characteristic voltage V c [the product of the critical current I c and the effective normal resistance R n(eff) ] of junctions, which determines high-frequency performance of the junction, was in the range of 0.1 endash 0.5 mV, and the critical current density J c in the range of 10 2 endash 10 4 A/cm 2 . Maximum-to-minimum variations in I c over a wafer were ±4% for junctions with V c =0.15mV and ±13% for junctions with V c =0.5mV. copyright 1997 American Institute of Physics
