    Full Text Available La teoría de la mente es la capacidad de inferir, predecir y atribuir estados mentales a otras personas. Este constructo ha sido estudiado desde numerosas patologías, como el autismo, la esquizofrenia y el síndrome de down. Estudios recientes han mostrado que las alteraciones de la teoría de la mente pueden ser observadas en los diferentes cuadros clínicos derivados de alteraciones del lóbulo frontal, como la personalidad antisocial. Algunos autores plantean que un aspecto esencial de la teoría de la mente es la empatía. Sin embargo, este constructo no ha sido estudiado en población normal colombiana con conductas violentas y delictivas que han estado vinculadas al conflicto armado. Este artículo tiene como propósito describir algunas características de la tom en sujetos que estuvieron vinculados al conflicto armado en antioquia con manifestaciones sintomáticas relacionadas con comportamientos violentos y delictivos.

    Full Text Available El nuevo y polémico régimen fiscal de operaciones vinculadas supone un cambio radical respecto de la regulación anterior a la Ley de Prevención del Fraude Fiscal de 2006, y pretende aproximar la normativa fiscal a los criterios expresados por las directrices de la OCDE sobre precios de transferencia, y a la nueva normativa contable, que se inspira en las Normas Internacionales de Contabilidad asumidas por la Unión Europea. Los principales cambios han afectado no solo al concepto de partes vinculadas (que se ha ampliado o la incorporación de los métodos de valoración de la OCDE, sino, sobre todo a: 1.La creación de una nueva obligación de documentación a cargo del obligado tributario que tiene que valorar sus operaciones a valor de mercado; 2.La creación de dos nuevas infracciones tributarias, para asegurar el cumplimiento de la obligación de documentación; 3.La simplificación del procedimiento de comprobación del valor normal de mercado; 4.La regulación expresa del denominado ajuste secundario. Pese a su novedad y por las presiones de los afectados, se han producido reformas para rebajar tanto las obligaciones de documentación como las sanciones, y, todo hace pensar que dado el contexto de crisis económica, puedan producirse más. The new and polemic fiscal regime of linked operations a radical change supposes respect of the regulation previous to the Law of Prevention of the Tax evasion of 2006, and tries to bring the fiscal regulation near to the criteria expressed by the directives of the OECD on prices of transfer, and to the new countable regulation, which inspires by the International Procedure of Accounting assumed by the European Union. The principal changes have concerned not only the concept of parts linked (that has been extended or the incorporation of the methods of valuation of the OECD, but, especially to: 1.The creation of a new obligation of documentation at the expense of the obliged tributary who has to

  4. Evolución geoquímica y temporal del magmatismo básico mesozoico en las Zonas Externas de las Cordilleras Béticas

    Full Text Available The Mesozoic basic magmatism found in the External Zones of the Betic Cordilleras (ZECB is represented either as «ophites» forming small dimension tectonic blocks intercalated in the Keuper gypsum-rich, clay sediments, or also as lava ilow bodies, most of them with pillow structures, within the Jurassic sedimentary rocks. Geochemical characteristics of these rocks indicate sorne differences between these two magmatic series. Two different chemical affinities have been carried out within the «ophites»: a with modal orthopyroxene and tholeiitic affinity; and b with modal olivine and transitionalalkaline affinity. Chemical characteristics of this last group are similar to those of the volcanic rocks from the Jurassic sediments. The field relationships found in sorne «ophite» outcrops al!ow us to deduce that the tholeiitic rocks are mostly present as extrusive rocks. However, their older whole-rock K-Ar ages range between 182 ± 9 and 187 ± 4 M.a., and do not correctly represent Upper Triassic ages. Transitional-alkaline «ophites» occur as subvolcanic rocks and their older obtained radiometric age is 137 ± 4 M.a. Al! these radiometric ages obtained may be intepreted as a result of the hybridization between the age of the Triassic magmatism and the very low- to low-grade metamorphism present in these rocks. This metamorphism is responsable for the new formed secondary paragenesis, made of prehnite + pumpel! yite + sericitie + mafic phyl!osicates. Radiometric age obtained in sorne intra-Jurassic volcanic rocks range between 155 ± 3 to 166 ± 4 M.a. These new radiometric data and field relationships are used to define the Mesozoic magmatic evolution in the ZECB. Tholeiitic magmatism was generated during an initial Triassic distensive stage. After this magmatic event, and as a consequence of an increment of the distensive regime, with important continental crust thickening, transitionalalkaline magmatism occurS. This

    2016-01-01

    Full Text Available Con el desarrollo de internet se ha ido haciendo evidente la vinculación entre discapacidad y sexualidad, en la que las designaciones “devotees”, “pretedenders” y “wannabes” (DPW juegan un rol central. Los devotees son individuos sanos que se sienten atraídos sexualmente hacia personas con discapacidad, generalmente con problemas de movilidad. Los pretenders son personas que actúan como si tuvieran una discapacidad imitando sus movimientos, usando muletas, sillas de ruedas, escayolas, etc. Por último, los wannabes desean ser discapacitados, algunos de ellos han llegado al extremo de hacerse amputaciones caseras cuando la medicina tradicional se ha negado a dar respuesta a su necesidad. La presente investigación documental indaga sobre cada uno de los miembros de la taxonomía DPW, presentando: a las hipótesis existentes con relación a su etiología; b su vinculación con otras entidades diagnósticas presentes en el DSM V; c se describen algunos de los tratamientos que se han empleado en su abordaje terapéutico, y d se mencionan las interrelaciones entre estas 3 categorías, dado que los limites entre ellas son muy flexibles.

  15. Fases y variables vinculadas a la desindustrialización: un análisis en dos escalas territoriales

    Directory of Open Access Journals (Sweden)

    Jaime Sobrino

    2012-01-01

    Full Text Available En los estudios sobre economía espacial y economía industrial suele afirmarse que la desindustrialización consiste en la pérdida de importancia de la industria manufacturera en el mercado de trabajo y en la estructura económica. Los factores asociados a dicha pérdida se dividen entre los vinculados con la integración vertical de los servicios de orden superior al proceso productivo, y los relacionados con la falta de competitividad para la producción de bienes. El propósito de este artículo consiste en aportar elementos conceptuales y evidencia empírica para caracterizar la desindustrialización como un proceso que atraviesa por diversas fases, que van desde el crecimiento industrial hasta la pérdida absoluta de empleo y producción; asimismo busca explorar variables asociadas a tal proceso. Para ello se utilizan los instrumentos estadísticos de análisis de correspondencias, los modelos log-lineales y las funciones de regresión logística. En una primera etapa el estudio incluye 88 países, y en la segunda se cambia la escala geográfica para enfocarse en las 90 áreas urbanas y metropolitanas más pobladas de México. Se concluye que la desindustrialización en ambas escalas territoriales (país y ciudad comparte elementos comunes relacionados con un menor crecimiento económico y un mayor peso de los servicios al productor. Pero también se observan especificidades, como la mayor velocidad y variabilidad del proceso en las ciudades respecto a los países. La desindustrialización debe ser vista como un proceso, aunque no siempre lineal ni tampoco circunscrito a las naciones más desarrolladas o a las ciudades de mayor tamaño.

    2014-10-01

    Full Text Available El artículo presenta criterios de evaluación para seleccionar las imágenes vinculadas con la práctica de actividad físico-deportiva en la edición de libros de texto de tal forma que estén libres de estereotipos. Los manuales escolares son portadores de un conocimiento que no siempre guarda una relación unívoca con lo que debe ser enseñado. La selección de sus contenidos debería ser coherente con las finalidades del sistema educativo, pero la investigación revela que la edición de los contenidos visuales no se corresponde con la aplicación de criterios que respondan a esa intencionalidad. Tras una aparente neutralidad, las imágenes de los libros de texto enmascaran prejuicios y reproducen desigualdades que afectan a determinados colectivos frágiles. Los criterios de evaluación para la selección de imágenes que se presentan en este trabajo fueron elaborados de acuerdo con los resultados de una investigación que analizó los estereotipos de género, edad, raza, discapacidad y tipología corporal en las imágenes de manuales escolares de educación física para la ESO en España, así como la percepción del alumnado de secundaria sobre una selección significativa de las mismas imágenes. Los criterios elaborados pueden aplicarse para la selección de fotografías destinadas a manuales de diferentes áreas de conocimiento en las que aparezcan representadas personas vinculadas a la práctica de actividad físico-deportiva. La aplicación de los criterios de evaluación se ejemplifica en la selección de contenidos visuales para un hipotético libro de educación física.

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

    Full Text Available O artigo analisa procedimentos do Tribunal de Contas (TC do Piauí para a verificação da receita e despesa vinculada à educação, constatando a oscilação e pouca clareza e firmeza na definição destes procedimentos. Por exemplo, embora a Constituição Estadual previsse o percentual mínimo de 30% em manutenção e desenvolvimento do ensino (MDE, o TC só passou a exigir este cumprimento a partir de uma resolução sua de 1998. Mesmo assim, admitiu que, no caso de Teresina e outros municípios, esta exigência viesse a ser cumprida gradualmente e só alcançasse os 30% em 2002. Em 2004, no entanto, reduziu esta exigência para 25%. Com relação à contabilização de receitas e despesas, os procedimentos também variaram. A Resolução n. 1.606, de 1998, por exemplo, não detalhou as receitas vinculadas à MDE. Na definição de despesas classificadas como MDE, o TC acrescentou alguns itens não previstos nos artigos 70 e 71 da LDB, confundindo gastos legalmente definidos como MDE com os classificados pela Lei do Orçamento Público.This paper examines the procedures adopted by the Audit Office (AO of the Brazilian State of Piauí to check the revenues and expenditures linked to education. It found that such procedures oscillate and are not very clearly and firmly defined. For example, although the State Constitution of Piauí stipulates that a minimum of 30% of tax revenue be earmarked to the legally-defined concept of maintenance and development of education (MDE, the AO only began to require it be enforced after a resolution issued in 1998. Yet, it allowed the capital city of Teresina and other townships to only gradually comply with it and reach 30% in the year of 2002. In 2004, however, the AO reduced this requirement to 25% (the minimum set by the Federal Constitution. As for the accounting of revenues and expenditures, procedures have also varied.

    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

Se analiza la dinámica interna de 536 familias distribuidas por tipología de la siguiente manera: 204 Monoparentales Femeninas; 11 Monoparentales Masculinas; 173 Extendidas; 109 Simultáneas y 39 Compuestas.La información se tomó de los registros de visita domiciliaria y entrevistas aplicados directa y personalmente por el grupo de asesores que tuvo a su cargo el proceso formativo y de orientación con las familias de niños y niñas de las instituciones educativas participantes. Es importante anotar que el modelo de intervención incluye la aplicación del cuestionario para evaluación de conductas en niños/niñas entre 3 y 11 años de edad (COPRAG, que permite identificar si están en riesgo de asumir conductas agresivas. Según el puntaje que obtienen en dicha prueba, se clasifican en 2 categorías: en la de "Índice" los niños y las niñas que aparecen en mayor riesgo y en la de "no Índice" quienes aparecen en menor riesgo. Por esto, el análisis de la información se hace diferenciando un grupo de otro.Las variables de la dinámica interna que se tuvieron en cuenta fueron: autoridad, comunicación, afectividad y pautas de crianza. Además se indagó sobre la percepción que las familias tienen de la salud física y emocional de estos niños y niñas.

    2015-05-01

    Full Text Available Un primer acercamiento a las reflexiones de Rem Koolhaas en torno a la tipología de torre introduce al rascacielos neoyorquino como la alegoría del “automonumen­to”: una construcción en esencia destinada a reafirmar su sola presencia y que se distingue del resto por medio de su estatura, que la monumentaliza. La torre de Babel, símbolo inquebrantable de la leyenda de la construcción en altura, escenifi­ca una historia de construcción y destrucción que está vinculada ineludiblemente al pensamiento crítico de Rem Koolhaas en torno a la torre como tipología desa­creditada. Un recorrido por las distintas “Babel” que Rem Koolhaas cataloga en el glosario de términos incluido en el texto SMLXL construye un discurso en torno a la destrucción de la torre bíblica y la construcción de la nueva Babel koolhaasiana que inicia su recorrido con el rascacielos para acabar reclamando un nuevo estado de monumentalidad: la ausencia en su estado más puro representado por el muro, el máximo ejemplo de ausencia como la forma más elevada de presencia monu­mental. Una mirada crítica que comienza con la torre metropolitana como la nueva Babel para finalizar con el muro como el monumento al vacío

    Full Text Available El presente artículo hace una revisión de cómo han realizado distintos tipos de ciudades su posicionamiento en el sistema global mediante el estudio de casos signifcativos. En la parte empírica, se realiza un análisis comparativo entre las actuaciones urbanas realizadas por 37 ciudades en dos periodos de tiempo diferentes: entre 1980 y 1995, que corresponde a la etapa de transición industrial, y entre 1995 y 2005, que responde a la etapa postindustrial. Se concluye que aquellas actuaciones vinculadas a la calidad de vida urbana y al marketing urbano han ido adquiriendo mayor relevancia que otras más vinculadas a la planifcación estratégica de carácter económico. Asimismo, las actuaciones de marcado carácter material dejan paso a otras más relacionadas con aspectos inmateriales. En suma, se observa un proceso de transición desde un modelo basado en los elementos tangibles de una ciudad hacia otro más preocupado en la búsqueda elementos inmateriales.Tis article reviews diferent city case studies in terms of their positioning in the global city system. In the empirical section there is a comparative analysis of 37 urban experiences across two periods of time: 1980-1995 which corresponds to the industrial transition, and 1995-2005 which relates to the post-industrial stage. Te article concludes that actions relating to urban quality of life and urban marketing are becoming more important than others more related to strategic economic planning. Furthermore actions of a more material nature are giving way to more immaterial ones. As such, a transition process can be observed fom a model based on tangible elementos of the city towards one more concerned with the recovery of more intangible assets.

    2014-05-01

    ALS is likely to be a disorder of multifactorial origin. Among all the factors that may increase the risk of ALS, environmental ones are being studied for many years, but in the recent years, several advances have pointed to a new interest in their potential involvement in the disease process, especially for the cyanotoxin BMAA. Food containing BMAA has been found on Guam, a well-known focus of ALS/parkinsonism/dementia and high levels of BMAA have been identified into the brain of these patients. The BMAA cyanotoxin is potentially ubiquitous and have also been found into the food of patients who died from ALS both in Europe and USA. BMAA can be wrongly integrated into the protein structure during mRNA traduction, competing with serine. This may induce abnormal protein folding and a subsequent cell death. Heavy metals, such as lead or mercury may be directly toxic for neuronal cells. Several works have suggested an increased risk of ALS in individuals chronically exposed to these metals. Exposure to pesticides has been suggested to be linked to an increased risk of developing ALS. The mechanism of their toxicity is likely to be mediated by paraoxonases. These proteins are in charge of detoxifying the organism from toxins, and particularly organophosphates. To date, there are insufficient scientific data to suggest that exposure to electromagnetic fields may increase the risk of having ALS. We are particularly missing longitudinal cohorts to demonstrate that risk. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Objective: To determine the genetic etiology in 2 consanguineous families who presented a novel phenotype of autosomal recessive juvenile amyotrophic lateral sclerosis associated with generalized dystonia. Methods: A combination of homozygosity mapping and whole-exome sequencing in the first family and Sanger sequencing of candidate genes in the second family were used. Results: Both families were found to have homozygous loss-of-function mutations in the amyotrophic lateral sclerosis 2 (juvenile) (ALS2) gene. Conclusions: We report generalized dystonia and cerebellar signs in association with ALS2-related disease. We suggest that the ALS2 gene should be screened for mutations in patients who present with a similar phenotype. PMID:24562058

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

    Full Text Available El desarrollo de una campaña de excavaciones en tres de los asentamientos castreños catalogados en la comarca de Laciana (noroeste de la provincia de León: La Muela, La Zamora y La Laguna, ha puesto de manifiesto la presencia de abundantes estructuras pétreas en los tres yacimientos, documentándose un total de cinco lienzos amurallados distintos así como diversas evidencias del hábitat interior de los poblados. Los materiales recuperados parecen señalar en los dos primeros casos unas amplias horquillas temporales que abarcan desde época protohistórica hasta el siglo II d.C., mientras que en La Laguna la ausencia de hallazgos muebles depara que su contextualización se realice a partir de las características morfológicas del emplazamiento. La abundancia de excavaciones en ámbitos castreños de zonas cercanas en Asturias y León permite encuadrar convenientemente los vestigios exhumados, organizándose éstos en dos apartados: sistemas defensivos y estructuras de hábitat. Por último, se avanzan una serie de hipótesis relativas a la naturaleza de los enclaves, fundamentalmente en lo que respecta a la posibilidad de una ocupación estacional en el Castro de La Muela para época astur vinculada al cercano asentamiento de La Zamora.

    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

    Full Text Available ENGLISH: During the last decades, the topos religion transformed into a powerful category of difference, which is also relevant for educationsystems and settings. 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. Rassismuskritische Ansätze ermöglichen es zumeist eherimplizit an Rassekonstruktionen anschließende Unterscheidungen zu erkennen und zu beschreiben, den Bedingungen ihres Wirksamwerdensnachzugehen sowie ihre Konsequenzen zu bestimmen. Eine rassismuskritische und migrationspädagogisch informierteReligionspädagogik ermöglicht AkteurInnen, weniger auf gewaltvolle Unterscheidungspraxen angewiesen zu sein undalternative Veränderungs- und Handlungsmöglichkeiten zu

    Full Text Available Este trabajo introduce el uso de grafos en el análisis de los determinantes del gasto de los turistas y lo aplica al estudio del comportamiento de los pasajeros de cruceros que desembarcan en Uruguay en los puertos de Montevideo y Punta del Este. Este enfoque ofrece un abordaje alternativo a los usualmente empleados para analizar los determinantes del gasto turístico al introducir una representación gráfica que permite sintetizar y visualizar las relaciones entre el conjunto de variables que caracterizan a los turistas o grupos de turistas y los determinantes de su nivel de gasto. En particular, la metodología permite representar las relaciones de dependencia entre variables (entre nodos adyacentes e independencias condicionadas (entre nodos no adyacentes. Para su aplicación, se consideran datos individuales de las encuestas realizadas a cruceristas correspondientes a la temporada de cruceros comprendida entre noviembre de 2014 y abril de 2015, ambos incluidos, en Uruguay. Se estudia la existencia de dependencias de las variables relativas a registrar el gasto de los cruceristas con otras variables (sociodemográficas, de contexto, etc.. El estudio muestra que las variables que mejor explican el comportamiento de los visitantes son las vinculadas al puerto de desembarco y al gasto. Asimismo, los resultados muestran que las variables socioeconómicas no están vinculadas al gasto en forma directa. || This paper introduces the use of graphs in the analysis of the determinants of tourists' expenditure, providing an alternative approach to the methods usually employed.

Se asume que si bien la función habitual que se imagina para el sistema carcelario es la de normalizar a los sujetos, esta función da lugar a una más económica: proteger a la sociedad de los desechos antropológicos que repetidamente produce la Modernidad en el presente. No obstante, dicha protección sacrifica las condiciones de posibilidad de los niños que en la cárcel comparten la condena de sus madres.

Se menciona el significado como lógica de la vida, junto a la necesidad de construcción de sentido que es lo que conforma la identidad, que aparece ligado a los problemas de organización individual y social. Las nociones de "sujeto" e "intermediación" completan el arsenal categorial, que se organiza en un doble eje: niveles y estado, donde se articula el proceso de constitución del sujeto y para lo cual se intenta responder a las preguntas ¿quién, cómo y para qué se organiza? Por último, se examina el papel de la vida cotidiana y del espacio público en esta construcción, para terminar con la relación entre identidad e ideología.

Comienzan a preocuparse, les gusta ser ecologistas. Se espera que no sea moda o novelería y que asuman el liderazgo para salvar al planeta, pues la deforestación, el incremento de la población, la quema de combustibles fósiles, el calentamiento global, el agujero de ozono sobre la Antártida dejan intuir que la Tierra está en grave peligro. Se recomienda entonces optar por un desarrollo sustentable.

Sin embargo, nos abocaremos al estudio desde el punto de vista procesal, en especial a lo referido al Debido Proceso. Para ello se analizará los presupuestos, la solución dada por la Excma. Corte Suprema y las consecuencias del mismo. Además, se criticará la solución dada, desde la óptica de las garantías procesales del imputado, contenidas en el nuevo proceso penal y lo dispuesto en la Constitución y la Convención Americana de Derechos Humanos. Finalmente, se argumentará en favor de una interpretación finalista y armónica de la Constitución y los tratados internacionales de derechos humanos.The verdict of the Pinochet Case has different ways of being analyzed: from the political, the constitutional, and the penal law points of view. 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.

    Full Text Available Islam, through the Quran, proclaims that its mission includes the teachings to the whole universe, Everything in the universe is maintained by Islam, and none of the symptoms are ignored. 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.

Este tipo de lesión representó el 6,2 % del total de tratadas en dicho período. En los atletas que jugaban con pelota y practicaban técnicas de combate hubo la mayor prevalencia de estas lesiones, fundamentalmente en los deportes de pelota, boxeo, baloncesto, karate y softbol. El impacto contra otro atleta fue el mecanismo de lesión más frecuente, sobre todo en los grupos de combate y juegos con pelota. Las fracturas de mandíbula dentoalveolares y cigomáticas resultaron ser los patrones de fracturas preponderantes. La conducta terapéutica en estos pacientes no difirió sustancialmente de la aplicada en aquellos con lesiones producidas por otras causas. La restricción de la actividad atlética osciló entre 9 y 15 semanas después del tratamiento inicial. En los atletas de alto rendimiento lesionados se impone establecer las estandarizaciones en su proceso rehabilitador para la toma de decisiones con respecto a su incorporación, tanto a la práctica como a la competencia, lo cual es fundamental en este sentido.A descriptive cross-sectional research study was made on 57 patients with facial fractures suffered during sporting activities. These patients had been seen by the Maxillofacial Surgery Service of "Saturnino Lara" provincial hospital in Santiago de Cuba from 1992 to 1996 and this type of lesions represented 6.2% of the fractures treated in this period of time. These lesions were more prevailing in athletes who mainly played ball sports, boxing, basketball, karate and softball. The collision with another sportsman was the most frequent injure mechanism fundamentally fight and ball sports. Dentoalveolar and zygomatic mandibular fractures were the predominant fracture patterns. Therapeutical procedures applied to these patients did not differ significantly from that followed in other types of lesions. Sports practicing interruption ranged from 9 to 15 weeks after the initial treatment. Regarding high performance athletes that get injured, it is necessary to set standards for their rehabilitation process to help in taking decisions as to their re-incorporation to sports practice and competition.

    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.

    The γ -ray emission associated with the radioactive decay of 26Al is one of the key pieces of observational evidence indicating stellar nucleosynthesis is an ongoing process in our Galaxy, and it was the first such radioactivity to be detected. Despite numerous efforts in stellar modeling, observation, nuclear theory, and nuclear experiment over the past four decades, the precise sites and origin of Galactic ^{26} Al remain elusive. We explore the present experimental knowledge concerning the destruction of ^{26} Al in massive stars. The precise stellar rates of neutron-induced reactions on ^{26} Al, such as (n,p) and (n, α , have among the largest impacts on the total ^{26} Al yield. Meanwhile, reactions involving the short-lived isomeric state of ^{26} Al such as radiative proton capture are highly-uncertain at present. Although we presented on-going experimental work from n_TOF at CERN with an ^{26} Al target, the present proceeding focuses only on the ^{26} Al isomeric radioactive beam production aspect and the first experimental results at CRIB.

    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

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.

    Full Text Available In some cases learning Nahwu was only stopped at the level of theory, yet its practice is still neglected. So many of the students mastered many nahwu theories but did not balance with the competence in listening, speaking, reading and writing in Arabic. It is true that learning Arabic is encouraged by nahwu, but the extent to which the model of Nahwu supports the language acquisition is questionable. Descriptive qualitative method was applied to deal with this research. The result showed that to master Arabic language through learning Nahwu, teachers should use al-Nahwu al-Wazhifi. Beside, they also can use this type of al-Nahwu al-'Ilmiy, giving examples of applicative and functional to complement existing examples in the book of al-Nahwu al-'Ilmi. In addition, because the books “al-Nahwu al-'Ilmy” had not been evaluated, teachers should develop aspects of evaluation by extending the exercise to hear, speak, read and write Arabic.

    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.

    Regions with reduced energy gap induced by the proximity effect give rise to quasi-particle loss in Josephson-junction X-ray detectors, but may also be used advantageously for quasi-particle collection. The influence of the thickness of the Al proximity layers in Nb/Al1,AlO(x),Al2/Nb Josephson tunnel junctions on the electrical characteristics has been investigated theoretically and experimentally. Theoretically it is found that the strength of the proximity effect is mainly determined by the proximity parameters gammaM1 (gammaM2) of the electrodes. Good fits of the measured I-V curves with theory were obtained for junctions with thicknesses dA11 ranging from 4 to 25 nm and dA12 = 3 nm, with gammaM2 about 0.12 and gammaM1/gammaM2 = dA11/dA12. For all junctions the proximity knee remains more pronounced than predicted.

    A search for reliability improvement of Al film interconnections has led to the introduction of Al-Alloy films such as Al-Cu, Al-Cu-Si and so on. This report describes the results of an in-depth study of Al, Al-Cu (2 wt % Cu) and Al-Cu-Si (2 wt % Cu - 1% Si) film interconnections and Silicon/Al-Alloy film contacts as they impact reliability of integrated circuits. Resistivity, microstructure and composition of Al-Alloy films vacuum deposited from an induction heated source (IN-Source) and dc magnetron sputter deposition techniques have been investigated and it is concluded that IN-Source and dc magnetron sputter deposition techniques are equally capable of producing Al, Al-Cu (2 wt %) and Al-Cu-Si (2 wt % Cu - 1% Si) films of comparable compositions, resistivity and microstructure. Chemical analysis X-ray fluorescence electron microprobe, scanning and transmission electron microscopy and ion microprobe have been employed for Al-Alloy film characterization. Availability of automated dc magnetron sputter (M-S) deposition equipment was a primary factor in the selection of magnetron sputter deposited Al-Alloy films for electromigration testing.

    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).

El estudio descriptivo correlacional se realizó con 41 niños y sus madres, aplicándose cuestionarios sobre funcionamiento familiar, prácticas de crianza y desarrollo infantil. Los resultados señalaron la existencia de un funcionamiento familiar caracterizado por una cohesión amalgamada y una adaptabilidad caótica, una disciplina complaciente, falta de control y de límites claros en la díada madre-hijo. Se trataba de familias monoparentales, donde la temprana edad de concepción, el madresolterismo y el apoyo de la familia extensa eran constantes. Las edades evolutivas registradas indicaron un desarrollo inferior a la edad cronológica, en la mayor parte de los casos; sin embargo, éstas tendieron a ser superiores al compararlas con la edades reales de los infantes. No se encontró una correlación estadísticamente significativa entre la edad de desarrollo y los diferentes factores del funcionamiento familiar para algunos de los rangos de edad considerados; sin embargo, no se lo descartó por completo, especialmente en lo referente al optimismo familiar

    Nonstoichiometry of metastable cubic {beta}{prime} and equilibrium tetragonal {beta} Al-Zr intermetallic phases of the nominal composition Al{sub 3}Zr in Al-rich alloys has been extensively studied. It is proposed that the ``dark contrast`` of {beta}{prime} core in {beta}{prime}/{sigma}{prime} complex precipitates, in Al-Li-Zr based alloys, is caused by incorporation of Al and Li atoms into the {beta}{prime} phase on Zr sublattice sites, forming nonstoichiometric Al-Zr intermetallic phases, rather than by Li partitioning only. {beta}{prime} particles contain very small amounts of Zr, approximately 5 at.%, much less than the stoichiometric 25 at.% in the Al{sub 3}Zr metastable phase. These particles are, according to simulation of high resolution images, of the Al{sub 3}(Al{sub 0.4}Li{sub 0.4}Zr{sub 0.2}) type. Nonstoichiometric particles of average composition Al{sub 4}Zr and Al{sub 6}Zr are observed also in the binary Al-Zr alloy, even after annealing for several hours at 600{degree}C.

    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.

    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.

  13. Structural analysis and magmatism characterization of the Major Gercino shear zone, Santa Catarina State, Brazil; Analise estrutural e caracterizacao do magmatismo da zona de cisalhamento Major Gercino, SC

    Passarelli, Claudia Regina

    1996-12-31

    This work describes the geometric and kinematic characteristics of the Major Gercino Shear Zone (MGSZ) in the Canelinha-Garcia area. This shear zone is one of the major lineaments that affect all southern Brazilian precambrian terrains. In Santa Catarina State, it separates, along its whole extension, the supracrustal rocks of the Brusque belt (northern part) from the Granitoid belt (southern). This zone is characterized by a regional NE trend and a dextral sense of movement where ductile-brittle structures predominate. The MGSZ is composed of two mylonitic belts separated by granitoid rocks probably associated to the development of the shear zone. Both shear zones show cataclastic to ultra mylonitic rocks, but mylonites and protomylonites conditions at high strain rate. The calc-alkaline granitoids present in the area can be grouped in two granitoid associations with meta to peraluminous affinities. The Rolador Granitoid Association is characterized by grayish porphyritic biotite-monzogranites and the Fernandes Granitoid Association by coarsed-grained to porphyritic pinkish amphibole-syenogranites. The U-Pb and Rb-Sr ages range from 670 to 590 Ma with the Sr{sup 87} / Sr{sup 86} initial ratios suggesting a crustal contribution in the generation of these rocks. The importance of the pure shear component is also emphasized by the results of the Fry method. Many z axes of the strain ellipses are at high angle to the shear foliation. Symmetric porphyroclasts also corroborate this hypothesis. The micaceous minerals formed during the shear development indicate K-Ar ages around 555 {+-} 15 Ma. Brittle reactivations of the shear zone have been placed by K-Ar in fine-fraction materials at Triassic time (215 {+-} 15 Ma.) 220 refs., 107 figs., 18 tabs., 4 maps

  16. Catalyzed precipitation in Al-Cu-Si

    Science.gov (United States)

    Mitlin, D.; Morris, J. W.; Radmilovic, V.

    2000-11-01

    The work reported here concerns the effect of Si on the precipitation of θ' phase (metastable Al2Cu) during the isothermal aging of Al-2Cu-1 Si (wt pct). The binary alloys Al-2Cu and Al-1 Si were studied for comparison. Only two precipitate phases were detected: essentially pure Si in Al-1 Si and Al-2Cu-1 Si, and θ' (metastable Al2Cu) in Al-2Cu and Al-2Cu-1Si. On aging the ternary alloy at 225 °C, Si precipitates first and catalyzes the θ' phase. The precipitates in the ternary alloy are smaller, are more densely distributed, have lower aspect ratios, and coarsen more slowly than those in the binary Al-2Cu aged at the same temperature. While the shapes of individual θ' precipitates in binary Al-2Cu are strongly affected by the kinetic problem of nucleating growth ledges, which produces a significant scatter in the aspect ratio for samples of given thickness, the overall evolution of particle shape with size follows the predictions of the Khachaturyan-Hairapetyan (KH) thermoelastic theory, which reduces to κ= L/d ∞ √ L at large sizes. The KH theory provides an estimate for the interfacial tension of the broad Al- θ' interface of 85 to 96 mJ/m2, which is near the values for other low-energy interfaces in Al, such as the twin boundary energy (100 mJ/m2) and the antiphase boundary energy in δ' Al3Li (70 mJ/m2). Si and θ' precipitates in Al-2Cu-1 Si have a strong elastic interaction because of their compensating strain fields. This elastic interaction promotes the nucleation of θ' precipitates on Si, decreases the expected aspect ratio of θ', and inhibits coarsening. Finally, Si precipitation in ternary Al-2Cu-1 Si differs from that in binary Al-1 Si in that the Si precipitates are coarser, more equiaxed, and more extensively twinned. These changes appear to be effects of Cu, which increases the solubility of Si in Al and adsorbs on the Si-Al interface, promoting twinning by a “step-poisoning” effect at the interface.

    Rafael, R.; Puyoo, E.; Malhaire, C.

    2017-11-01

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

    Full Text Available La categoría colonial del mestizo fue un recurso ideológico, formador de la identidad nacional en la posrevolución mexicana. El eje indio-mestizo sirvió para organizar las interacciones étnicas y las políticas del estado. Médicos y antropólogos reforzaron esta taxonomía dual en estudios de poblaciones humanas, produciendo con marcadores biomédicos y descripciones diferenciadas del indio y del mestizo. Las descripciones genómicas han contribuido tanto a la construcción de una noción cientificista del mestizo arraigada en porcentajes de ancestría india, europea y africana, como al surgimiento de dos objetos tecnocientíficos que llamamos el mestizo molecular y el mestizo bioinformático. Aquí describimos las interacciones entre las encarnaciones ideológicas y científicas del mestizo.

    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.

    Background and Purpose Ethnic minorities are at higher stroke risk than non-Hispanic whites yet are less likely to have optimal vascular risk factor control. There is a need to develop culturally sensitive strategies for enhancing vascular risk reduction in minority patients with stroke. This study aimed to develop a postdischarge report card to boost treatment adherence among elderly Spanish-speaking patients with stroke within an urban health system. Methods This study included a total of 13 Spanish-only speaking participants aged ≥60 years discharged from a local government hospital in Los Angeles within 18 months of an index ischemic stroke and 6 caregivers engaged in focus groups and interviews. Structured interviews were conducted with 11 care providers and 9 administrators at the hospital. Framework analysis examined the data and elicited themes to adapt a pre-existing patient report card tool. Results Spontaneously using the same phrase, “Al pie de la letra,” several participants expressed a need to follow medical instructions accurately to prevent recurrent stroke and identified barriers/facilitators for doing so. They made comments about the pre-existing report card, advising several changes, including the clarification of phrases, and written instructions to explain the need for the card and how to fill it out. The providers and administrators recommended avenues for successfully using the card at the hospital. A new report card was created that incorporated all major perspectives. Conclusions Crafting a culturally sensitive tool for promoting treatment adherence in elderly Spanish-only-speaking patients with stroke within an urban health system using a participatory methodology is feasible. The efficacy of this new report card should be tested in a randomized controlled trial. PMID:20167904

    Full Text Available One method of legal istinbâth agreed upon by the ushul fiqh scholars is al-qiyâs. In al-qiyâs was appeared some serious problems dealing with the search for al-'illat. Al-'illat as one of the obligation of al-qiyâs occupies the most important position, so that the method of al-qiyâs can be applied in the future correctly, and will give legal decision correctly. In searching for al-'illat, the ushul fiqh scholars use logic of linguistic typically in the search for truth, the other hand they also must be able to impulse, imagination, and creativity in decide on a case, and they are no longer so glued rigidly to the al-qath'iyyah al-dalâlah. One way to look for al-'illat is al-manâth, which divided into three parts, namely tanqîh al-manâth, tahqîq al-manâth, and takhrîj al-manâth. Searching for the truth of qiyâs method stresses on logical translation that sometimes mix with intuition, imagination and creativity. Therefore, qiyâs can go down to the law problems related to the people’s attitude deeper. While al-manath is one of the methods to look for al-illat where the ulama ushul fiqh draw their intuition, imagination, and creations to solve some problems, and they are not too stiff to qath’î theoremsCopyright (c 2015 by Al-Ihkam.

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

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

  11. 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 The grain refinement limits of commercial pure Al inoculated by Al-5Ti-1B, Al-5Ti-0.25C and Al-5Ti-0.3C-0.2B master alloys were studied, and the influence of melting temperature on the grain refining performance of these three master alloys was investigated using a high scope video microscope (HSVM, a field-emission scanning electron microscope (FESEM, an electron probe micro-analyzer (EPMA and X杛ay diffraction (XRD method. Results show that there is a grain refinement limit of commercial pure Al refined by these three master alloys; with the same addition level of 1.5% under the present experimental conditions, the grain refinement limits (smallest average grain size of commercial pure Al refined by Al-5Ti-1B, Al-5Ti-0.25C and Al-5Ti-0.3C-0.2B master alloys are 50 祄, 80 祄 and 80 祄, respectively. In addition, with an increase in the melting temperature of the pure Al, the grain refining performance of Al-5Ti-1B and Al-5Ti-0.25C master alloys decreases, but the grain refining performance of Al-5Ti-0.3C-0.2B changes little.

    The microstructure and phase composition of Al/Ti/Al interfaces with respect to their localization were investigated. An aluminum-flyer plate exhibited finer grains located close to the upper interface than those present within the aluminum-base plate. The same tendency, but with a higher number of twins, was observed for titanium. Good quality bonding with a wavy shape and four intermetallic phases, namely, TiAl3, TiAl, TiAl2, and Ti3Al, was only obtained at the interface closer to the explosive material. The other interface was planar with three intermetallic compounds, excluding the metastable TiAl2 phase. As a result of a 100-hour annealing at 903 K (630 °C), an Al/TiAl3/Ti/TiAl3/Al sandwich was manufactured, formed with single crystalline Al layers. A substantial difference between the intermetallic layer thicknesses was measured, with 235.3 and 167.4 µm obtained for the layers corresponding to the upper and lower interfaces, respectively. An examination by transmission electron microscopy of a thin foil taken from the interface area after a 1-hour annealing at 825 K (552 °C) showed a mixture of randomly located TiAl3 grains within the aluminum. Finally, the hardness results were correlated with the microstructural changes across the samples.

    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

    Genetic discoveries in ALS have a significant impact on deciphering molecular mechanisms of motor neuron degeneration. The identification of SOD1 as the first genetic cause of ALS led to the engineering of the SOD1 mouse, the backbone of ALS research, and set the stage for future genetic breakthroughs. In addition, careful analysis of ALS pathology added valuable pieces to the ALS puzzle. From this joint effort, major pathogenic pathways emerged. Whereas the study of TDP43, FUS and C9ORF72 pointed to the possible involvement of RNA biology in motor neuron survival, recent work on P62 and UBQLN2 refocused research on protein degradation pathways. Despite all these efforts, the etiology of most cases of sporadic ALS remains elusive. Newly acquired genomic tools now allow the identification of genetic and epigenetic factors that can either increase ALS risk or modulate disease phenotype. These developments will certainly allow for better disease modeling to identify novel therapeutic targets for ALS.

    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.

    Full Text Available Ultrathin films of alumina were investigated by a compact kMC-model. Experimental jV-curves from Al/AlOx/Au-junctions with plasma- and thermal-grown AlOx were fitted by simulated ones. We found dominant defects at 2.3-2.5 eV below CBM for AlOx with an effective mass mox∗=0.35 m0 and a barrier EB,Al/AlOx≈2.8 eV in agreement with literature. The parameterization is extended to varying defect levels, defect densities, injection barriers, effective masses and the thickness of AlOx. Thus, dominant charge transport processes and implications on the relevance of defects are derived and AlOx parameters are specified which are detrimental for the operation of devices.

A lot of verses of Quran give indication of people to learn more about thinking than memorizing. The past occurrence mirrors the instructional dynamics of human learning. The instructors are not only Allah, but also people, bird, and nature. Al-Qur’an always learns human being based on concrete media support even if the items are eschatology and theology. The instructional conception of Quran must not only use term ‘allama-yu‘allimu, but also yuwâri, yatafakkaru containing instructional elements. This reality shows that instructional concepts of Quran put more nuances of concrete-media than abstract-verbal ones.Abstrak:  Semua ayat al-Qur’an terbuka untuk ditafsirkan dalam berbagai konteks keilmuan, termasuk pendidikan.

    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.

    Four potential novel phases of AlP (Pmn21-AlP, Pbam-AlP, Pbca-AlP and bct-AlP) are proposed in this study and the stabilities are verified by the enthalpy, independent elastic constants and phonon dispersion spectra. The electronic and mechanical properties of ten AlP phases are studied and the electronic properties are calculated by hybrid functional. All the ten phases possess the properties of semiconductor. Pmn21-AlP and Pbam-AlP have electronic advantages over wz-AlP and zb-AlP at 0 GPa for their direct band gaps. Our calculated band gaps are 3.22, 3.27, 3.47, 3.04, 2.57, 0.62, 1.38, 3.34, 2.09 and 2.71 eV for Pmn21-AlP, Pbam-AlP, Pbca-AlP, bct-AlP, cI24-AlP, hR18-AlP, oC12-AlP, wz-AlP, zb-AlP, and Cmcm-AlP, respectively. Additionally, Pmn21-AlP, Pbam-AlP, Pbca-AlP, bct-AlP, cI24-AlP, hR18-AlP, wz-AlP, and Cmcm-AlP behave in a ductile manner, and oC12-AlP and zb-AlP behave in a brittle manner.

    This paper provides a brief review of the recent progress in research and development of Ni{sub 3}Al and its alloys. Emphasis has been placed on understanding low ductility and brittle fracture of Ni{sub 3}Al alloys at ambient and elevated temperatures. Recent studies have resulted in identifying both intrinsic and extrinsic factors governing the fracture behavior of Ni{sub 3}Al alloys. Parallel efforts on alloy design using physical metallurgy principles have led to properties for structural use. Industrial interest in these alloys is high, and examples of industrial involvement in processing and utilization of these alloys are briefly mentioned.

    Two AlInN/AlN/GaN heterostructures with 280-nm- and 400-nm-thick AlN buffer grown on sapphire substrates by metal-organic chemical vapor deposition (MOCVD) have been investigated by x-ray diffraction (XRD), atomic force microscopy (AFM), photoluminescence (PL) and Hall-effect measurements. The symmetric (0002) plane with respect to the asymmetric (10bar{1}2) plane in the 280-nm-thick AlN buffer has a higher crystal quality, as opposed to the 400-nm-thick buffer. The thinner buffer improves the crystallinity of both (0002) and (10bar{1}2) planes in the GaN layers, it also provides a sizeable reduction in dislocation density of GaN. Furthermore, the lower buffer thickness leads to a good quality surface with an rms roughness of 0.30 nm and a dark spot density of 4.0 × 108 cm-2. The optical and transport properties of the AlInN/AlN/GaN structure with the relatively thin buffer are compatible with the enhancement in its structural quality, as verified by XRD and AFM results.

    2014-02-01

    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.' ' '

    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

  15. Interdiffusion in Diffusion Couples: U-Mo v. Al and Al-Si

    Interdiffusion and microstructural development in the U-Mo-Al system was examined using solid-tosolid diffusion couples consisting of U-7wt.%Mo, U-10wt.%Mo and U-12wt.%Mo vs. pure Al, annealed at 600°C for 24 hours. The influence of Si alloying addition (up to 5 wt.%) in Al on the interdiffusion microstructural development was also examined using solid-to-solid diffusion couples consisting of U-7wt.%Mo, U-10wt.%Mo and U-12wt.%Mo vs. pure Al, Al-2wt.%Si, and Al-5wt.%Si annealed at 550°C up to 20 hours. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electron probe microanalysis (EPMA) were employed to examine the development of a very fine multiphase intermetallic layer. In ternary U-Mo-Al diffusion couples annealed at 600°C for 24 hours, interdiffusion microstructure varied of finely dispersed UAl3, UAl4, U6Mo4Al43, and UMo2Al20 phases while the average composition throughout the interdiffusion zone remained constant at approximately 80 at.% Al. Interdiffusion microstructure observed by SEM/TEM analyses and diffusion paths drawn from concentration profiles determined by EPMA appear to deviate from the assumption of “local thermodynamic equilibrium,” and suggest that interdiffusion occurs via supersaturated UAl4 followed by equilibrium transformation into UAl3, U6Mo4Al43, UAl4 and UMo2Al20 phases. Similar observation was made for U-Mo vs. Al diffusion couples annealed at 550°C. The addition of Si (up to 5 wt.%) in Al significantly reduced the thickness of the intermetallic layer by changing the constituent phases of the interdiffusion zone developed in U-Mo vs. Al-Si diffusion couples. Specifically, the formation of (U,Mo)(Al,Si)3 with relatively large solubility for Mo and Si, along with UMo2Al20 phases was observed along with disappearance of U6Mo4Al43 and UAl4 phases. Simplified understanding based on U-Al, U-Si, and Mo-Si binary phase diagrams is discussed in the light of the beneficial effect of Si alloying addition.

    TiAlC, TiAlCN, TiAlSiCN, TiAlSiCO, and TiAlSiO layers of thicknesses 2.2 μm, 755, 491, 393, and 431 nm, respectively, were deposited on stainless steel, silicon, and glass substrates to study their refractive indices and extinction coefficients using the phase-modulated spectroscopic ellipsometry in the wavelength range of 300-1200 nm. Absorption coefficient of each layer was calculated from the extinction coefficient of the layer. The results indicate that the first three layers (i.e., TiAlC, TiAlCN, and TiAlSiCN) are absorbing in nature, while TiAlSiCO and TiAlSiO act as intermediate and antireflection layers. Subsequently, a tandem absorber of TiAlC/TiAlCN/TiAlSiCN/TiAlSiCO/TiAlSiO with layer thicknesses of 62, 20, 18, 16, and 27 nm, respectively, was deposited on stainless steel substrates to fabricate a spectrally selective coating with absorptance of 0.961 and emittance of 0.15 at 82 °C. The obtained refractive indices and extinction coefficients of the tandem absorber were used to simulate the reflectance of the deposited tandem absorber using SCOUT software. Simulated reflectance data of the tandem absorber showed a good agreement with the experimental data measured by UV-Vis-NIR and FTIR spectrophotometry. The angular dependence of the selective properties of the tandem absorber was studied by measuring the reflectance spectra of the tandem absorber at different incident angles.

    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.

  5. 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

    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.

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

    Full Text Available This article discusses Shâdhilîyah, one of the most recognized sufi orders, which possesses quite distinct aspects in the conception of its mystical teachings. This sufi order was founded by Abû al-H}asan al-Shâdhilî, a sufi who has moderate and open view of the worldly life. Al-Shâdhilî explained about how a sufi should behave towards and deal with worldly matters. Although al-Shâdhilî asserted that a person who practice tasawwuf should not pay more adoration on the worldly matters (hubb al-dunyâ, the person does not have to abhor and leave such lively aspects as wealth and position behind. The most important thing to a sufi, according to al-Shadhili, is how he obeys the requirements of shar‘ by avoiding away from immoral deeds and at the same time recognizing God in his heart (ma‘rifat Allâh. Al-Shâdhilî initiated tasawuf ‘amalî which is affiliated to the Ahl al-Sunnah wa al-Jamâ‘ah school, an Islamic mystical thought that adheres to the principles of sharî‘ah based on the foundation of al-Qur’ân dan H}adîth. The concept of al-Shâdhilî’s tasawuf has been subsequently revealed into the great sufi order spectrum, namely al-Shâdhilîyah, where during its historical development this sufi order has led to the emergence of many branches with different names.Keywords: Shâdhilîyah, open view, hubb al-dunyâ, ma‘rifat Allâh.

    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.

    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.

    2016-02-01

    Quantum chemical calculations with the use of hybrid density functional with perturbative second-order correlation and dispersion correction are carried out to study the reactions of Al, AlO and AlOH with the H2O2 molecule. The values of energy barriers are estimated by means of extrapolation to the basis set limit. The energetically favorable reaction pathways have been revealed during the examination of the potential energy surfaces. Complex character of the processes under study has been established. It has been found that the initial stages of the considered processes are barrierless. Appropriate rate constants for principal channels of the reactions under study have been estimated by using capture model and canonical variational theory. The Arrhenius approximations for these channels have been proposed for the temperature range T = 300-4000 K.

    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.

    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)

  16. Study on Mg/Al Weld Seam Based on Zn–Mg–Al Ternary Alloy

    Directory of Open Access Journals (Sweden)

    Liming Liu

    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.

  17. Rupture of Al matrix in U-Mo/Al dispersion fuel by fission induced creep

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

    This work has shown that rapidly solidified AlSi alloy is more resistant than AlCu when exposed in either neutral or acidic chloride solutions. This can be related to Si, metalloid element, which accelerates active dissolution of the alloy surface and causes rapid formation of a passive film and subsequent enrichment of Al in the film. This is in agreement with the views of Naka et al. on the role of metalloid elements, like phosphorus, in promoting the corrosion resistance of amorphous alloys. (orig.)

    Al-5wt.%Si-Al2O3, Al-10wt.%Si-Al2O3, Al-20wt.%Si-Al2O3 composites were fabricated by powder metallurgy and in-situ reactive synthesis technology. The impact of the addition of Si on the thermal and electrical properties was tested and analysed for vary in silicon content in Al-Si-Al2O3 composites. Results show that both thermal expansion coefficient and thermal conductivity decreased as silicon content increased because Si and Al2O3 dispersed in the Al matrix uniformly to suppress the high thermal expansion of Al to a large extent as well as the interfacial thermal resistance which led to the decline in thermal conductivity. Electrical resistivity increased when silicon content was increased because low thermal expansion coefficient particles of Si and Al2O3 severely damaged the continuity of the Al matrix which hindered movement of electron in the matrix.

    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.

  13. ALS and FTD: an epigenetic perspective.

    2016-10-01

    Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are two fatal neurodegenerative diseases seen in comorbidity in up to 50 % of cases. Despite tremendous efforts over the last two decades, no biomarkers or effective therapeutics have been identified to prevent, decelerate, or stop neuronal death in patients. While the identification of multiple mutations in more than two dozen genes elucidated the involvement of several mechanisms in the pathogenesis of both diseases, identifying the hexanucleotide repeat expansion in C9orf72, the most common genetic abnormality in ALS and FTD, opened the door to the discovery of several novel pathogenic biological routes, including chromatin remodeling and transcriptome alteration. Epigenetic processes regulate DNA replication and repair, RNA transcription, and chromatin conformation, which in turn further dictate transcriptional regulation and protein translation. Transcriptional and post-transcriptional epigenetic regulation is mediated by enzymes and chromatin-modifying complexes that control DNA methylation, histone modifications, and RNA editing. While the alteration of DNA methylation and histone modification has recently been reported in ALS and FTD, the assessment of epigenetic involvement in both diseases is still at an early stage, and the involvement of multiple epigenetic players still needs to be evaluated. As the epigenome serves as a way to alter genetic information not only during aging, but also following environmental signals, epigenetic mechanisms might play a central role in initiating ALS and FTD, especially for sporadic cases. Here, we provide a review of what is currently known about altered epigenetic processes in both ALS and FTD and discuss potential therapeutic strategies targeting epigenetic mechanisms. As approximately 85 % of ALS and FTD cases are still genetically unexplained, epigenetic therapeutics explored for other diseases might represent a profitable direction for the

  14. Direct Laser Cooling Al{}^{+} Ion Optical Clocks

    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.

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

  4. Distribution and size of lava shields on the Al Haruj al Aswad and the Al Haruj al Abyad Volcanic Systems, Central Libya

    Science.gov (United States)

    Elshaafi, Abdelsalam; Gudmundsson, Agust

    2017-05-01

    The Al Haruj Volcanic Province (AHVP) consists of two distinct volcanic systems. In the north is the system of Al Haruj al Aswad, covering an area of 34,200 km2, while in the south the system of Al Haruj al Abyad, covering an area of 7,850 km2. The systems have produced some 432 monogenetic volcanoes, primarily scoria (cinder) cones, lava shields, and maars. The density distribution of the volcanoes in each system, plotted as eruption points or sites, has a roughly elliptical surface expression, suggesting similar plan-view geometry of the magma sources, here suggested as deep-seated reservoirs. More specifically, the Al Haruj al Aswad magma reservoir has major and minor axes of 210 km and 119 km, respectively, and an area of 19,176 km2, the corresponding figures for the Haruj al Abyad reservoir being 108 km and 74 km, for the axes, and 6209 km2 for the area. We measured 55 lava shields on the AHVP. They are mostly restricted to the northern and southern parts of AHVP and date from late Miocene to (at least) the end of Pleistocene, while some may have been active into Holocene. In fact, although primarily monogenetic, some of the lava shields show evidence of (possibly Holocene) fissure eruptions in the summit parts. The early lava shields tend to be located at the edges of volcanic systems and with greater volumes than later (more central) shields. The average lava shield basal diameter is 4.5 km and height 63 m. There is strong linear correlation between lava shield volume and basal area, the coefficient of determination (R2) being about 0.75. When 22 Holocene Icelandic lava shields are added to the dataset, for comparison, the correlation between volume and basal area becomes R2 = 0.95. Numerical models suggest that the local stress fields favoured rupture and dyke injection at the margins of the source reservoirs during late Miocene - early Pliocene, in agreement with the distribution of the early, large-volume shields.

    Directional solidification of eutectic alloys is a promising technique for producing in-situ composite materials exhibiting a balance of properties. Consequently, the microstructure, creep strength and fracture toughness of directionally solidified NiAl-NiAlTa alloys were investigated. Directional solidification was performed by containerless processing techniques to minimize alloy contamination. The eutectic composition was found to be NiAl-15.5 at% Ta and well-aligned microstructures were produced at this composition. A near-eutectic alloy of NiAl-14.5Ta was also investigated. Directional solidification of the near-eutectic composition resulted in microstructures consisting of NiAl dendrites surrounded by aligned eutectic regions. The off-eutectic alloy exhibited promising compressive creep strengths compared to other NiAl-based intermetallics, while preliminary testing indicated that the eutectic alloy was competitive with Ni-base single crystal superalloys. The room temperature toughness of these two-phase alloys was similar to that of polycrystalline NiAl even with the presence of the brittle Laves phase NiAlTa.

Tafsir al- Manâr is a masterpiece that has become a manifestation characterizes HAMKA’s thought and aspiration as a celebrated Muslim scholar and a man of letters. It contains various critical ideas and message of renewals that stimulate the reader to stand still and improve the aspects of religious, education, social, economic and politics of the Muslim community. This study is an attempt to see clearly to what extent the relationship between the commentary of al-Azhar with that of Muhammad ‘Abduh’s. This study is a library research on al-Azhar as well as Muhammad ‘Abduh’s al-Manâr. The most important outcome of the study is that the interpretation applied in al-Azhar has a very close relationship with that of reform movement exegesis led by Muhammad ‘Abduh. Many an idea of ‘Abduh’s reforms are adopted by HAMKA. The writing of the al-Azhar itself has a significant connection with the scholarship profile and academic services that have been inherited by ‘Abduh.

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

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

    NiCrAlY/NiAl multi-layered coating was produced on SUS310S steel by means of mutual low pressure plasma spraying of NiCrAlY and Al powders which was accompanied with self-propagating high-temperature synthesis (SHS) reaction of metal deposits. The NiAl layer contained Ni3Al particles and Cr2Al phase along the fine grain boundary. Also, Ni3Al was detected in the NiCrAlY layer with a small amount of NiAl particles. As the result, high hardness was obtained in both the layers, i.e., 650HV in NiAl layer and 450HV in NiCrAlY one at 673K. The structure of the multilayered coating changed hardly during annealing lower than 973K because enriched Cr at NiCrAlY/NiAl interface suppressed NiAl + Ni3Al{yields}Ni5Al3 peritectoid reaction. The SHS reaction time of an compressed Al droplet in diameter of 50{mu}m was calculated as 4.17times10{sup -3} second. 20 refs., 9 figs., 3 tabs.

  3. Management of respiratory symptoms in ALS.

    LENUS (Irish Health Repository)

    Hardiman, Orla

    2012-02-01

    Respiratory insufficiency is a frequent feature of ALS and is present in almost all cases at some stage of the illness. It is the commonest cause of death in ALS. FVC is used as important endpoint in many clinical trials, and in decision-making events for patients with ALS, although there are limitations to its predictive utility. There are multiple causes of respiratory muscle failure, all of which act to produce a progressive decline in pulmonary function. Diaphragmatic fatigue and weakness, coupled with respiratory muscle weakness, lead to reduced lung compliance and atelectasis. Increased secretions increase the risk of aspiration pneumonia, which further compromises respiratory function. Bulbar dysfunction can lead to nutritional deficiency, which in turn increases the fatigue of respiratory muscles. Early recognition of respiratory decline and symptomatic intervention, including non-invasive ventilation can significantly enhance both quality of life and life expectancy in ALS. Patients with respiratory failure should be advised to consider an advance directive to avoid emergency mechanical ventilation.

    1994-03-01

    The creep behavior of powder metallurgy (PM) 6061 Al, which has been used as a metal matrix alloy in the development of discontinuous silicon carbide reinforced aluminum (SiC-Al) composites, has been studied over six orders of magnitude of strain rate. The experimental data show that the steady-state stage of the creep curve is of short duration; that the stress dependence of creep rate is high and variable; and that the temperature dependence of creep rate is much higher than that for self-diffusion in aluminum. The above creep characteristics are different from those documented for aluminum based solid-solution alloys but are similar to those reported for discontinuous SiC-Al composites and dispersion-strengthened (DS) alloys. Analysis of the experimental data shows that while the high stress dependence of creep rate in 6061 Al, like that in DS alloys, can be explained in terms of a threshold stress for creep, the strong temperature dependence of creep rate in the alloy is incompatible with the predictions of available threshold stress models and theoretical treatments proposed for DS alloys.

  19. Management of respiratory symptoms in ALS.

    LENUS (Irish Health Repository)

    Hardiman, Orla

    2011-03-01

    Respiratory insufficiency is a frequent feature of ALS and is present in almost all cases at some stage of the illness. It is the commonest cause of death in ALS. FVC is used as important endpoint in many clinical trials, and in decision-making events for patients with ALS, although there are limitations to its predictive utility. There are multiple causes of respiratory muscle failure, all of which act to produce a progressive decline in pulmonary function. Diaphragmatic fatigue and weakness, coupled with respiratory muscle weakness, lead to reduced lung compliance and atelectasis. Increased secretions increase the risk of aspiration pneumonia, which further compromises respiratory function. Bulbar dysfunction can lead to nutritional deficiency, which in turn increases the fatigue of respiratory muscles. Early recognition of respiratory decline and symptomatic intervention, including non-invasive ventilation can significantly enhance both quality of life and life expectancy in ALS. Patients with respiratory failure should be advised to consider an advance directive to avoid emergency mechanical ventilation.

    COMENTARIO AL LIBRO " EL MUNDO PSICOLÓGICO DE KAFKA" POR EL ACADÉMICO ADOLFO DE FRANCISCO ZEA.

     

    Fui invitado en forma comedida, por el doctor Adolfo De Francisco, para comentar su obra: "El Mundo Psicológico de Kafka". Respondí que no era literato y menos crítico de Kafka. Sin embargo, acepté
    hacerlo siendo consciente de las limitaciones que me acompañan y para las que pido de todos ustedes su consideración. Tenía sí el deseo al reto de lo incógnito.
    Además sus argumentos fueron contundentes, pues se referían al compromiso con la Academia y, sin decírmelo, era también con él en nuestra historia compartida. Mis motivaciones y expectativas personales conscientes eran múltiples para sumergirme en sus ideas que mueven el espíritu desde la piel a lo trascendente, de lo interno a lo externo y viceversa, y en que cada palabra puede ser objeto de análisis profundo, pues esa es su esencia. Por ejemplo cuando el doctor De Francisco se refiere a la sublimación y a la estética, a la política, a la religiosidad, a la burguesía, al campesinado, a la nobleza, al absolutismo, al arte o a la historia, a la cosmovisión sociológica y literaria, al psicoanálisis para afrontar la realidad interna y externa, entonces el autor penetra en el mundo de la fantasía y del psiquismo, para entender el simbolismo implícito de Kafka.
    Las motivaciones personales inconscientes, pertenecen a las tendencias irracionales de hundirme en espacios complejos para luego intentar'ordenarlos; en medio está
    la contratransferencia que me une con el autor Adolfo De Francisco y otra la que se refiere a la temática kafkiana...

    This study proposes a facile solution process to generate a reduced graphene oxide (rGO) protection layer on Al, in which polyvinyl alcohol (PVA) is used to enhance interfacial bonding between Al and rGO. A multi-level analysis indicated that PVA-aided coating induced numerous conjugations between Al and rGO by producing a large number of hydroxyl groups on the Al surface. The Al plate directly coated by rGO showed good corrosion resistance compared with the pristine Al, implying that rGO may act as an effective corrosion barrier for Al. Moreover, the Al coated by the PVA-aided process exhibited higher corrosion resistance than the directly coated Al as well as the pristine Al due to the enhanced adhesion between Al and rGO.

    In this study, a mechanochemical route to synthesize a Cu-Al layered double hydroxide (LDH) and a methyl orange (MO) intercalated one (MO-LDH) was introduced, in which basic cupric carbonate (Cu{sub 2}(OH){sub 2}CO{sub 3}) and aluminum hydroxide (Al(OH){sub 3}) with Cu/Al molar ratio at 2/1 was first dry ground for 2 h and then agitated in water or methyl orange solution for another 4 h to obtain the LDH and MO-LDH products without any heating operation. The prepared samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Thermogravimetry (TG), Differential scanning calorimetry (DSC) and Scanning electron microscopy (SEM). The products showed high crystallinity phase of Cu-Al and MO intercalated Cu-Al LDH with no evident impurities, proving that the craft introduced here was facile and effective. The new idea can be applied in other fields to produce organic-inorganic composites. - Highlights: • A facile mechanochemical route to synthesize Cu-Al and MO intercalated Cu-Al LDH. • The products possesses high crystalline of LDH phase with no impure phases. • The dry milling process induces the element substitution between the raw materials. • The agitation operation helps the grain growth of LDH.

    In pursuit of lightweighting of automobiles and low emission of transportation, the efforts to develop high-strength, heat-resistant and fatigue-resistant Al alloys and/or composites have been ongoing. Here we report a novel Al matrix composite with ultrahigh strength reinforced by a three dimensional network of nano-AlN particles for the first time. The in-situ synthesized AlN particles are connected by twinning bonding chains and built up a three dimensional network strengthening Al matrix enormously like the skeleton to human body. The composite containing 16.4wt.% AlN particles shows excellent properties: the ultimate tensile strengths can be up to 518MPa at room temperature and 190MPa at 350 °C. This peculiar performance results from the novel spatial distribution of nano-scale AlN particles. Our findings in this work would help to develop a potential candidate for high-performance heat resistance light-metal based materials.

    Compound semiconductors based on GaN have multiple functional applications. Useful compositions include GaN, and ternary and quaternary compositions of (AlGaIn)N. Defects arising from lattice mismatch, point defects, or impurities may act as electrical trapping centers and degrade device efficiency. Current-voltage, capacitance-voltage, thermal admittance spectroscopy (TAS), and deep level transient spectroscopy (DLTS) measurements are applied to characterize the defects in Al0.40Ga0.80N and In0.18Al0.82N in this report. Broad peaks with a shoulder at high temperature dominate the DLTS spectra in each of the materials. An acceptor trap associated with a dislocation appears at 340 K in AlGaN. The defect has an energy of 0.2 eV and capture cross section of 10-21 cm2. A second trap at 0.35 eV, 10-14 cm2 appears in the TAS measurements in addition to the trap at 0.2 eV. Defects in InAlN are dominated by a peak near 150 K. Two traps appear in the TAS measurements. Both traps in the InAlN are acceptors, based on a lack of field dependent emission rates using double pulse DLTS (DDLTS). The two energy levels in InAlN appear to be coupled, with only one state occupied at a time.

    Cutaneous leishmaniasis (CL) is an endemic parasitic infection in the Mediterranean region, including Libya and its Al-jabal Al-gharbi province. We aimed at studying the occupational relevance as well as other epidemiological aspects of CL. We investigated 140 CL cases who attended at Gharyan outpatient polyclinic during a period of 6 months in 2009. CL infection was clinically diagnosed and confirmed by demonstration of Leishmania parasites on smears from lesions. Our findings showed that males were more affected than females (P=0.04), and people above 10-years were more affected than younger ones (P=0.0001). A significant percent of CL cases belonged to Al-Kawasem subprovince (P=0.0001). Farm-related activities were the most frequent occupations among CL cases (P=0.04). In addition to farm workers, housewives and students are at risk groups since they are engaged at farm activities. Moreover, those who have occupations that require staying outdoors for a part of night, e.g., policemen, are also at risk. Compared to children, adult CL patients had multiple lesions (P=0.001) that were more prevalent in their upper and lower extremities than the face (P=0.0001). We conclude that CL is a major health problem in Al-jabal Al-gharbi province of Libya. The presence of rodents and sandflies makes it a suitable environment for Leishmania to spread in an endemic epidemiological pattern. Being engaged in farming activities or outdoor occupations increases the risk of infection. Various clinical patterns of CL suggest the presence of more than 1 species of Leishmania at Al-jabal Al-gharbi province. We propose that the 2 species responsible for CL in this area are L. major and L. tropica. Further investigations to identify the leishmanial species responsible for CL at Al-jabal Al-gharbi together with adoption of preventive and control programs are needed.

    Nuclear pore complexes (NPCs) play important roles in traffic of molecules between the nucleus and cytoplasm, aberrant distributions of components of NPCs were demonstrated in C9orf72 amyotrophic lateral sclerosis (C9-ALS) patients, but it is elusive whether such abnormities are also the case with other cause of ALS disease. In the present study, we investigated the spatiotemporal distributions of RanGAP1 and 4 representative nucleoporins (GP210, NUP205, NUP107 and NUP50) of NPCs in human Cu/Zn superoxide dismutase-1 mutation transgenic (SOD1-Tg) mice and sporadic ALS patients. Compared with wild type (WT), these proteins displayed age-dependent and progressive nuclear precipitations, and cytoplasmic aberrant expressions in motor neurons of lumbar cord in SOD1-Tg mice from 10 to 18weeks (W). Double immunofluorescent analysis showed abnormal nuclear retention and apparent co-localizations of RanGAPl with NUP205 and NUP205 with NUPl07, meanwhile, GP210 with NUP205 mainly co-localized in the nuclear envelope (NE) of motor neurons. Furthermore, RanGAP1, GP210 and NUP50 showed similarly abnormal nuclear precipitations and cytoplasmic upregulations in SOD1-Tg mice and ALS patients, moreover, aberrant co-localizations of RanGAP1 with TDP-43 and NUP205 with TDP-43 were also observed in motor neurons. The present study indicated that the mislocalization of these proteins of NPCs may underlie the pathogenesis of ALS both in SOD1-Tg mice and human sporadic ALS patients, and these dysfunctions may be a fundamental pathway for ALS that is not specific only in C9-ALS but also in SOD1-ALS, which may be amenable to pharmacotherapeutic intervention.

    Research in metaphor processing has made extensive use of the normed metaphor database created by Katz, Paivio, Marschark, & Clark (Metaphor and Symbolic Activity, 3, 191-214, 1988). Because of the plasticity of figurative language, we conducted a renorming of selected metaphors from the database on a new student population. Correlations between Katz et al.'s and the present data showed that the pattern of responses has remained highly consistent across time and populations. The consistency of the normative ratings allows us to be confident in future research that will use the Katz et al. collection.

    Using the first-principles calculations, the elastic properties, anisotropy properties, electronic structures, Debye temperature and stability of Fe-Al (Fe{sub 3}Al, FeAl, FeAl{sub 2}, Fe{sub 2}Al{sub 5} and FeAl{sub 3}) binary compounds were calculated. The formation enthalpy and cohesive energy of these Fe-Al compounds are negative, and show they are thermodynamically stable structures. Fe{sub 2}Al{sub 5} has the lowest formation enthalpy, which shows the Fe{sub 2}Al{sub 5} is the most stable of Fe-Al binary compounds. These Fe-Al compounds display disparate anisotropy due to the calculated different shape of the 3D curved surface of the Young’s modulus and anisotropic index. Fe{sub 3}Al has the biggest bulk modulus with the value 233.2 GPa. FeAl has the biggest Yong’s modulus and shear modulus with the value 296.2 GPa and 119.8 GPa, respectively. The partial density of states, total density of states and electron density distribution maps of the binary Fe-Al binary compounds are analyzed. The bonding characteristics of these Fe-Al binary compounds are mainly combination by covalent bond and metallic bonds. Meanwhile, also exist anti-bond effect. Moreover, the Debye temperatures and sound velocity of these Fe-Al compounds are explored.

    Electronic properties of endohedrally doped armchair single-walled carbon nanotubes (SWCNTs) with a chain of six Al atoms have been studied using ab-initio density functional theory. We investigate the binding energy/atom, ionization potential, electron Affinity and Homo-Lumo gap of doped armchair SWNTs from (4,4) to (6,6) with two ends open. BE/dopant atom and ionization potential is maximum for (6, 6) doped armchair carbon nanotube; suggest that it is more stable than (4, 4) and (5, 5) doped tubes. HOMO - LUMO gap of Al doped arm chair carbon nanotubes decreases linearly with the increase in diameter of the tube. This shows that confinement induce a strong effect on electronic properties of doped tubes. These combined systems can be used for future nano electronics. The ab–initio calculations were performed with SIESTA code using generalized gradient approximation (GGA).

    Much activity has been concentrated on the development of intermetallic compounds with the aim of improving tensile ductility, fracture toughness and high notch sensitivity in order to develop an attractive combination of properties for high and low temperature applications. This paper reports experience in processing and forging of FeAl intermetallic of B2 type. During the experiments two different temperatures were employed, and the specimens were forged after annealing in air, 10{sup {minus}2} torr vacuum and argon. From the results it was learned that annealing FeAl in argon atmosphere prior to forging resulted in better deformation behavior than for the other two environments. For the higher forging temperature used in the experiments (700C), the as-cast microstructure becomes partially recrystallized.

    Ductile Ni{sub 3}Al and Ni{sub 3}Al-based alloys have been identified for a range of applications. These applications require the use of material in a variety of product forms such as sheet, plate, bar, wire, tubing, piping, and castings. Although significant progress has been made in the melting, casting, and near-net-shape forming of nickel aluminides, some issues still remain. These include the need for: (1) high-strength castable composition for many applications that have been identified; (2) castability (mold type, fluidity, hot-shortness, porosity, etc.); (3) weld reparability of castings; and (4) workability of cast or powder metallurgy product to sheet, bar, and wire. The four issues listed above can be {open_quotes}show stoppers{close_quotes} for the commercial application of nickel aluminides.

    By progression of the disease, motor neurons degenerate in patients with amyotrophic lateral sclerosis (ALS) eventually lose nearly all voluntary muscles in the body. They are awake and aware but cannot move or communicate (locked-in state). Since the function of the brain is preserved, one possible measure to support their communication is to interpret their motor intention by decoding (deciphering) brain signals and present it with external devices. This technology called "brain-machine interface (BMI)" is now close to clinical use in Japan and USA.In our system, we record electrocorticogram (ECoG) obtained with subudural electrodes during their motor imagery, decode it and determine the movement they intended. So far, one patient of ALS with severe paralysis, implanted with this electrodes, successfully operated the PC communication tool only by thinking.

    We consider the cospatial production of elements in supernova explosions to find observationally detectable proxies for enhancement of {sup 26}Al in supernova ejecta and stellar systems. Using four progenitors we explore a range of 1D explosions at different energies and an asymmetric 3D explosion. We find that the most reliable indicator of the presence of {sup 26}Al in unmixed ejecta is a very low S/Si ratio ({approx} 0.05). Production of N in O/S/Si-rich regions is also indicative. The biologically important element P is produced at its highest abundance in the same regions. Proxies should be detectable in supernova ejecta with high spatial resolution multi wavelength observations, but the small absolute abundance of material injected into a proto-planetary disk makes detection unlikely in existing or forming stellar/planetary systems.

    Full Text Available Almost all people with amyotrophic lateral sclerosis (ALS experience a motor speech disorder, such as dysarthria, as the disease progresses. At some point, 80 to 95% of people with ALS are unable to meet their daily communication needs using natural speech. Unfortunately, once intelligibility begins to decrease, speech performance often deteriorates so rapidly that there is little time to implement an appropriate augmentative and alternative communication (AAC intervention; therefore, appropriate timing of referral for AAC assessment and intervention continues to be a most important clinical decision-making issue. AAC acceptance and use have increased considerably during the past decade. Many people use AAC until within a few weeks of their deaths.

    Systemic AL amyloidosis is one of the differential diagnosis of chronic musculoskeletal disease, especially when swollen and painful joints is associated with claw hands. Ultrasound evaluation is a good diagnosis tool, showing a characteristic joint and tendon involvement and assisting in guided biopsy procedure. We report a 55 year old caucasian woman, diagnosed for two years with RA without improvement under different DMARDs, admitted for fixed flexion contractures of both hands ("claw hands"), worsening pain and swelling of small joints of hands and feet, elbows and shoulders. Pad shoulder sign and bilateral anterior wrist and elbow pads, macroglossia, thickened skin of fingers and ecchymotic rashes on forearm and around eyes were observed. Ultrasound examinations showed subdeltoid and bicipitoradial bursitis, presence of inhomogeneous hypoechoic material around bicipital tendons and tenosinovitis of the extensor tendons of the hand, and synovial thickening of elbow and shoulder joints. Complete analysis of the bone marrow biopsy and biopsy specimens from subacromial bursa were positive for AL amyloidosis.

    Full Text Available Powder samples of Al/Al2O3/Gr hybrid composites with different weight percents were obtained by mechanical alloying in a high energy ball mill. The aim of this study is to investigate the effect of alumina and graphite particles content on the microstructure of Al/Al2O3/Gr hybrid composites. Results obtained using Scanning Electron Microscopy (SEM as well as Energy-Dispersive X-ray Spectroscopy (EDS show that the addition of alumina particles as the reinforcement has a drastic effect on the size and morphology of the composite powders. Also, the addition of graphite particles as one of the reinforcing components is presumed to improve tribological properties by forming a graphite-rich lubricant film between the sliding surfaces.

    A method of mechanical synthesis in a planetary ball mill produced composite powders based on a nanocrystalline Al-Mg matrix reinforced with micro additives of Al / MWCNTs. The granulometric composition of the obtained composite powders was studied. It has been established that the concentration of Al / MWCNTs does not significantly affect the average particle size of the composite powder formed in the process of mechanical synthesis. The resulting composite powders were studied by X-ray diffraction analysis. The influence of the Al / MWCNTs concentration on the size of the coherent scattering regions of the synthesized powder is determined. The morphology of the resulting composite powders was studied by high-resolution scanning microscopy. The resulting powders can be used in the creation of bulk composite materials and functional coatings.

    Popularitas Imam Bukhari sebagai penyusun kitab Hadits memiliki posisi yang tinggi di kalangan masyarakat muslim. Kitab Al-Jami ‘al-Shahih karya Imam  Bukhari dianggap sebagai koleksi hadits terbaik setelah Quran. Namun, tidak ada banyak informasi tentang kemampuannya di bidang Hukum Islam (fiqh. Ada beberapa pertanyaan yang dapat diajukan dalam hal tersebut;  pertama, apakah pemikiran Imam Bukhari dipengaruh salah satu dari empat fuqaha Sunni saat menulis al-Jami ‘al-Shahih?. Kedua, apa yang diupayakan Imam Bukhari untuk mengartikulasikan pemikirannya tentang hukum Islam? Dengan menggunakan pendekatan eksploratif, verifikatif dan hermenetical, artikel ini akan mengungkapkan bahwa Imam Bukhari tidak berada di bawah pengaruh madhab tertentu dalam mengartikulasikan pemikirannya tentang hukum Islam. Dia mengartikulasikan pandangannya dengan cara yang unik dan execelent berdasarkan kapasitasnya sebagai muhaddits.

    Marcela Gómez-Suárez

    Full Text Available RESUMEN Cerca de 38% de embarazos no planeados se dan por necesidades insatisfechas en anticoncepción. En las mujeres positivas al VIH, las cifras se triplican, un fenómeno explicado por determinantes sociales como la pobreza, el acceso a los servicios de salud, la violencia y el desplazamiento forzoso, todos ellos elementos propios de la vida de estas mujeres. Los embarazos no planeados representan una carga psicológica vinculada con el temor de transmitir la infección a sus hijos, la orfandad y el asumir los riesgos durante el embarazo, a lo cual se añaden las consecuencias familiares y sociales que se manifiestan en baja asistencia al control prenatal, descuido de la salud y aumento de la posibilidad de transmisión vertical. El asesoramiento en anticoncepción diferencial e integrado a los servicios de atención y control del VIH es básico para lograr la eliminación de la transmisión vertical del VIH a corto y medio plazo. Reconocer que estas mujeres tienen características diferentes a las de la población general, como expresan su vida reproductiva, sus deseos e intenciones sobre la maternidad y que los embarazos no planeados representan una carga psicológica, social y económica adicional a la de las demás mujeres permitiría que el asesoramiento en anticoncepción se proporcionara en los programas de atención y seguimiento del VIH, en el mismo lugar y momento, con personal capacitado, capaz de comprender y atender sus necesidades reproductivas dentro de un marco de derechos, logrando que los sistemas de salud, basados en la responsabilidad que tienen con la sociedad, fueran capaces de ofrecer un asesoramiento en reproducción de calidad y dirigido a satisfacer las necesidades específicas de estas mujeres.

    Full Text Available For the current study the Lazarian stress-coping theory and the appendant model of psychosocial adjustment to chronic illness and disabilities (Pakenham 1999 has shaped the foundation for identifying determinants of adjustment to ALS. We aimed to investigate the evolution of psychosocial adjustment to ALS and to determine its long-term predictors. A longitudinal study design with four measurement time points was therefore, used to assess patients’ quality of life, depression, and stress-coping model related aspects, such as illness characteristics, social support, cognitive appraisals and coping strategies during a period of two years. Regression analyses revealed that 55% of the variance of severity of depressive symptoms and 47% of the variance in quality of life at T2 was accounted for by all the T1 predictor variables taken together. On the level of individual contributions, protective buffering and appraisal of own coping potential accounted for a significant percentage in the variance in severity of depressive symptoms, whereas problem management coping strategies explained variance in quality of life scores. Illness characteristics at T2 did not explain any variance of both adjustment outcomes. Overall, the pattern of the longitudinal results indicated stable depressive symptoms and quality of life indices reflecting a successful adjustment to the disease across four measurement time points during a period of about two years.Empirical evidence is provided for the predictive value of social support, cognitive appraisals, and coping strategies, but not illness parameters such as severity and duration for adaptation to ALS. The current study contributes to a better conceptualization of adjustment, allowing us to provide evidence-based support beyond medical and physical intervention for people with ALS.

However, the reality is precesely the social conflict among the society. This article explores the issue of diversity contained in al Qur’an. Some of the key themes included: diversity as sunnatullah, diversity in unity, religious and ethnic diversity, and diversity of professions. Al Qur’an has mentioned several groups of religious believers and provided guidance association order among religious believers. Religious diversity certainly makes Muslim necessitates acknowledging and respecting other religion save Islam. Al Qur’an has mentioned also a variety of occupations based on interests, talents, expertise, and particular skills. The fragmentation and understanding diversity have caused by egoism and truth claiming of each group and individual, but no one has knowledge covering everything from different sides or corners. Above all knowledge is the Almighty owner off all knowledge. With feeling most true someone or group tends to feel the best and have the right to insult any others. That is the base of the dispute and spiritual decline. Mukmin has to preserve the noble character in association, and keep away from bad manner. Among mukmin must love each other and maintain good manners. Finally, this study is intended to promote the establishment of harmony, peace and happiness of living together.

    Experimentally it has been determined that if a composite containing a reinforcement which has a different (in general lower) thermal coefficient of expansion as compared to the matrix, then upon cooling from the processing or annealing temperature, plastic relaxation of the misfit strain will occur. Also, experimentally it has been shown that as the size of the reinforcement is increased, i.e., from small spheres to large spheres, there is a decrease in the summation of the effective plastic strain in the matrix. In other words there is a decrease in the average dislocation density in the matrix. However, if the shape of the reinforcement is changed from spherical to short fiber to continuous filament, then the dislocation density increases. This experimental data is obtained at a constant volume fraction. A very simple model of plastic relaxation based on prismatic punching of dislocations from the interface can account for the decrease in the dislocation density with an increase reinforcement size, and the increase in dislocation density when changing the shape from a sphere to a continuous filament. A FEM analysis of the shape factor is also capable of predicting the correct trend. However, at present the continuum mechanics methods that have been investigated can not predict the size dependence. A simple model to explain the size effect in Al{sub 2}O{sub 3}/NiAl composites based on the deformation characteristics of NiAl will be discussed.

    Al-Andalus society (711-1492) based its idea of health on the wisdom of Classical Greece, the Hippocratic-Galenic theories, as well as the Persian and Hindu cultures. The twelfth century in al-Andalus is considered to be the most prolific period for works of a scientific and technical nature. At the time, the main treatises on dietetics were written and this science reached its widest expression with such leading figures as Ibn Wāfīd, Avenzoar, Averroes and Maimonides, whose works revealed the first scientific knowledge on the nutritional processes of the human body. Diet was regarded as being essential for health and the prevention of disease. Dietary guidelines were written for different age groups, different body types and different seasons of the year. The amount of food to be ingested, the number of meals recommended and the order in which the food should be consumed were all issues that were discussed. A variety of foods were thought to have medicinal properties, some of which are known today. The diet in al-Andalus was varied and very probably made a substantial contribution to the origin of the present-day Mediterranean diet, rich in olive oil, wholemeal cereals, fruit and vegetables, fish, lamb, poultry, nuts and spices. We also find that many of the terms in current use in diet and agriculture are a living testimony to the Arabic influence, as are many of the dishes of our varied Mediterranean gastronomy.

  13. Model for metabolic resistance against ALS inhibitors

    Richter, Otto

    2014-02-01

    Full Text Available Due to herbicide selection pressure metabolic resistance has evolved in many weed species. In this paper we analyse the interaction between the branched chain amino acid (BBC pathway and detoxifying pathways for herbicide breakdown. The four phase detoxification pathway of herbicides comprising the action of P450, GST, glycosyltransferase and ABC transporter is modelled by a system of coupled enzyme kinetic reactions represented by nonlinear differential equations. The herbicide under consideration inhibits the enzyme ALS, which is the key enzyme for the biosynthesis of branched amino acids. For the kinetics of ALS a Monod approach is employed with a binding site for the inhibitor. Synthetic and detoxification pathways are coupled. The model is used to study the production of branched amino acids under the action of ALS inhibitors for different structures and modes of action of the detoxification pathway. The model is capable of generating typical dose response curves and their shift in dependence of the activity pattern of the enzymes of the detoxification pathway of the inhibitor.

    The type-I to type-II band alignment transition in InAlAsAs/AlGaAs/GaAs self-assembled quantum dots (QDs) is investigated when the Al-composition in QDs and barrier are changed. In particular, the In0.46Al0.54As/Ga0.46Al0.54As/GaAs QDs show unique optical properties. The PL peak energy has a blue-shift of >40 meV when the laser intensity increases by four orders of magnitude, indicating a type-II band alignment of the QDs. The formation of the type-II band alignment is explained by that the quantum-confinement effect pulls up the minimum electron energy level in the QDs and the Γ→X transition in the Ga0.46Al0.54As barrier. The time-resolved PL (TRPL) spectrum of QDs at peak wavelength exhibits a double-component decay behavior, suggesting the possibility of type-I and type-II band alignment coexistence in this QD sample. The continuum state of the QDs is also investigated. Emission associated with the continuum states of the QDs is directly observed in PL spectra. The PL excitation (PLE) and TRPL spectra reveal an efficient carrier relaxation from the AlGaAs barrier into the InAlAs QD ground state via the continuum states. The carrier recombination in the continuum states can compete with that in the QDs due to the long recombination lifetime in the type-II QDs. This feature of continuum state emission can not be observed for normal InGaAs/GaAs QDs with the type-I band structure.

    A thermal neutron absorbing material, comprised of 28.4 vol% HfAl3 in an Al matrix, was developed to serve as a conductively cooled thermal neutron filter to enable fast flux materials and fuels testing in a pressurized water reactor. In order to observe the microstructural change of the HfAl3-Al composite due to neutron irradiation, an EBSD-FIB characterization approach is developed and presented in this paper. Using the focused ion beam (FIB), the sample was fabricated to 25µm × 25µm × 20 µm and mounted on the grid. A series of operations were carried out repetitively on the sample top surface to prepare it for scanning electron microscopy (SEM). First, a ~100-nm layer was removed by high voltage FIB milling. Then, several cleaning passes were performed on the newly exposed surface using low voltage FIB milling to improve the SEM image quality. Last, the surface was scanned by Electron Backscattering Diffraction (EBSD) to obtain the two-dimensional image. After 50 to 100 two-dimensional images were collected, the images were stacked to reconstruct a three-dimensional model using DREAM.3D software. Two such reconstructed three-dimensional models were obtained from samples of the original and post-irradiation HfAl3-Al composite respectively, from which the most significant microstructural change caused by neutron irradiation apparently is the size reduction of both HfAl3 and Al grains. The possible reason is the thermal expansion and related thermal strain from the thermal neutron absorption. This technique can be applied to three-dimensional microstructure characterization of irradiated materials.

    Full Text Available Al-Madinah Al-Munawwarah is the second holiest site in Islam. The possibility of new emerging microbes is valid due to the increased number of pilgrims. The objectives of the current study were to estimate the numbers of fungi and bacteria inside and outside Al-Haram Al-Nabawi and to find whether new bacterial and fungal species have emerged compared to previous studies. Air samples were collected twice a day from 12 spots and four directions during the pilgrim year of 2013 for four consecutive weeks by using the sedimentation method. Thirty five genera and fifty eight species were identified. The most recovered bacterial genera were Staphylococcus, Micrococcus, Bacillus, and Dermacoccus with 32.47%, 18.18%, 12.85%, and 11.23%, respectively. Fifty nine isolates of fungi were molecularly identified. Aspergillus species had the highest percentage (78%. The other fungal genera identified (Alternaria triticina, Emericella nidulans, Emericella striata, Mucor circinelloides, Penicillium chrysogenum, Penicillium minioluteum, Rhizopus arrhizus, Rhizopus oryzae, and Syncephalastrum racemosum had less than 5% frequency. In places such as Al-Haram Al-Nabawi, a large and crowded public (millions exist especially during pilgrimages and Ramadan, thus, exposure to microorganisms is high. On the other hand, microorganism infectivity depends on many factors including their virulence, landing site, and person’s immunity. For those reasons, many aspects should be considered to avoid aerosol contaminants.

    To assess the effect of eligibility criteria in amyotrophic lateral sclerosis (ALS) clinical trials on the representativeness of the enrolled population. Patients enrolled in 8 placebo-controlled clinical trials in our ALS center from 2003 to 2008 were compared 1) to the patients included a prospective epidemiologic register (Piemonte and Valle d'Aosta register for ALS, PARALS) in the same period and 2) the subset of PARALS patients who met the usual criteria for inclusion in clinical trials (PARALS-ct) (definite, probable, probable laboratory-supported ALS; age between 18 and 75 years; disease duration enrolled in 8 different clinical trials. The PARALS cohort included 813 patients, of whom 539 (66.3%) met the entry criteria for clinical trials. Patients enrolled in clinical trials were different from both epidemiologic cohorts, since they were younger, had a longer diagnostic delay, and were more likely to have a spinal onset, and to be men. Tracheostomy-free survival was significantly longer in the group of patients enrolled in clinical trials (median survival time, trial patients, 3.9 years [95% confidence interval (CI) 3.4-4.4]; PARALS, 2.6 [2.4-2.8]; PARALS-ct, 2.9 [2.7-3.1]). Patients enrolled in clinical trials do not satisfactorily represent the ALS population; consequently, the findings of ALS trials lack of external validity (generalizability). Efforts should be made to improve patients' recruitment in trials, particularly enrolling incident rather than prevalent cases.

    Full Text Available Tafsīr al-Kashshāf, is a tafsīr written by a Muslim scholar who support ahl al-'adl wa al-tawḥīd or known as Mu'tazilah. This tafsīr is influenced by power relations, the terms referred to Michel Foucault, that served ideological interests. This articles employs analytical descriptive to investigate the doctrines of Mu'tazilah that influenced al-Zamakhsharī in his methodological interpretation of tafsīr al-Kashshāf . The result of this study shows that the doctrines of Mu'tazilah influenced al-Zamakhshari’s interpretation of the Qur’anic verses accommodating to the opinion of the Hanafi School and the theology of Mu'tazilah. He tried to confine understanding of verses by changing their meanings in accordance with the five creeds of Mu’tazilah as follows: al-tawḥīd, al-‘adl, al-wa’d wa al-wa’īd, al-manzilat bayna al-manzilatain, and al-‘amr bī al-ma’rūf wa al-nahy ‘an al-munkar.  On the other side, tafsīr al-Kashshāf employed tahlīlī method and bi al-ra'y model of interpretation. Tafsīr al-Kashshāf utilized critical reasoning in its interpretation, employed the principles of freedom, applied Arabic grammatical (naḥwu, provided qirā’ah-qirā’ah, and showed the beauty of literary and language styles of the Qur’an.

    The present experiment was carried out in order to know the resistance mechanism of the ectomycorrhizal (ECM) fungi under Al stress, to establish the theoretical foundation to alleviate the Al toxicity of trees, to guide the selection of Al-resisted ECM fungi and preserve forest health. The absorption and assimilation of Al3+ by four ECM fungi [Pisolithus tinctorius (Pt 715), Suillus luteus (Sl 08 and Sl 14), Gyroporus cyanescens (Gc 99)], which were isolated from different forest soils, were investigated in pure culture in liquid media. The growths of Pt 715 and Sl 08 were less affected by Al3+, but growths of S114 and Gc 99 were obviously inhibited by Al3+. With the increasing of Al3+ concentration in culture, the absorption and assimilation of Al3+ by four ECM fungi increased. It indicated that the concentration of Al3+ in environments might be the primary factor determining the Al3+ content in the cell of each tested fungi. Amounts of Al3+ absorbed (in total or calculated in unit hyphae) by the Al3+ tolerant strains (Pt 715 and Sl 08) were significantly lower than those by the Al3+ sensitive strains (S1 14 and Gc 99), which illustrated that reducing the absorption of Al3+ under Al3+ stress environment might be an effective approach to alleviate the Al3+ poison for these Al3+ tolerant strains. Furthermore, Al3+ stress could stimulate the ECM fungi to assimilate more N, P, and K, which might indicate that increasing requirement of the nutrients also could be helpful for ECM fungi to fight against the harmful effects caused by Al3+ stress.

    The giant polyaluminum species [Al32O8(OH)60(H2O)28(SO4)2](16+) (S-Al32) and [Al13O4(OH)25(H2O)10(SO4)](4+) (S-K-Al13) [S means that sulfate ions take part in coordination of the aluminum polycation; K represents the Keggin structure] were obtained in the structures of [Al32O8(OH)60(H2O)28(SO4)2][SO4]7[Cl]2·30H2O and [Al13O4(OH)25(H2O)10(SO4)]4[SO4]8·20H2O, respectively. They are the first two aluminum polyoxocations coordinated by sulfate ions. The "core-shell" structure of S-Al32 is similar to that of Al30, but the units are linked by two [Al(OH)2(H2O)3(SO4)](-) groups with replacement of four η(1)-H2O molecules. The structure of S-K-Al13 is similar to the well-known structure of ε-K-Al13, but the units are linked by two (SO4(2-))0.5 with replacement of a H3O(+) ion. It was shown that strong interaction exists between the polyoxocations and counterions. On the basis of their structural features and preparation conditions, a formation and evolution mechanism (from ε-K-Al13 to S-K-Al13 and S-Al32) has been proposed. A local basification degree symmetrical equalization principle was extracted based on a comparison of the calculated results of the local basification degree for each central Al(3+) ion included in a polycation. They can be used to explain how the two aluminum species are formed and evolved and why the sulfate ions can coordinate to them and to predict where the OH-bridging positions will be upon further hydrolysis.

    2013-03-01

    Fine dispersion of disordered phases is obtained in a Ni-Al-Co and Fe-Al-Co ternary system. A transmission electron microscopy investigation has been performed in the present work on the precipitation of supersaturated B2-ordered (Ni,Co)Al and α-Fe in B2-ordered FeAl(Co) with different stoichiometries. Precipitation behavior and hardening were investigated by measuring the hardness variation. The hardness of (Ni,Co)Al and B2-FeAl(Co) increased appreciably by the fine precipitation of (Ni,Co)2Al, α-Fe, and overage softening occurred after prolonged aging. In case of B2-ordered (Ni,Co)Al, the (Ni,Co)2Al phase had a hexagonal structure and took a rod-like shape with the long axis of the rod parallel to the directions of the B2 matrix. By aging at temperatures below 873 K, a long period superlattice structure appeared in the hexagonal (Ni,Co)2Al phase. The orientation relationship between the (Ni,Co)2Al precipitates and the B2-(Ni,Co)Al matrix was (0001)p//(111)B2 and [bar 12bar 10]_p //[bar 110]_{B2}, where the suffix p and B2 denote the (Ni,Co)2Al precipitate and the B2-(Ni,Co)Al matrix, respectively. (Ni,Co)Al hardened appreciably by the fine precipitation of the (Ni,Co)2Al phase. On the other hand, in case of B2-FeAl(Co), the disordered α-Fe phase was present as a precipitate in a B2-FeAl(Co) matrix and had a cubic-cubic orientation with the matrix. At the early aging periods, prismatic dislocation loops formed in the B2-FeAl(Co) matrix. B2-FeAl(Co) matrix was typically hardened by the precipitation of α-Fe.

    Combination of mechanical alloying and friction stir processing was used for the fabrication of Al/(Al13Fe4 + Al2O3) nano-composites. Pre-milled hematite + Al powder mixture was introduced into the stir zone generated on 1050 aluminum alloy sheet by friction stir processing. Uniform and active milled powder mixture reacted with plasticized aluminum to produced Al13Fe4 + Al2O3 particles. Al13Fe4 intermetallic showed elliptical shape with a typical size of 100 nm, while nano-sized Al2O3 exhibited irregular floc-shaped particles that formed clusters with the remnant of iron oxide particles in the fine recrystallized aluminum matrix. As the milling time (1-3 h) of the introduced powder mixture increased, the volume fraction of Al13Fe4 + Al2O3 particles increased in the fabricated composite. The hardness and ultimate tensile strength of the fabricated nano-composites varied from 54.5 to 75 HV and 139 to 159 MPa, respectively; these are much higher than those of the friction stir processed base alloy (33 HV and 97 UTS). The highest hardness and strength were achieved for the nano-composite fabricated using the 3-h milled powder mixture; hard nano-sized reaction products and fine recrystallized grains of Al matrix had major and minor roles on enhancing these properties, respectively.

    2017-08-01

    We designed two transmission-mode GaAs/AlGaAs photocathodes with different Al x Ga1-x As layers, one has an Al x Ga1-x As layer with the Al component ranging from 0.9 to 0, and the other has a fixed Al component 0.7. Using the first-principle method, we calculated the electronic structure and absorption spectrum of Al x Ga1-x As at x = 0, 0.25, 0.5, 0.75 and 1, calculation results suggest that with the increase of the Al component, the band gap of Al x Ga1-x As increases. Then we activated the two samples, and obtained the spectral response curves and quantum efficiency curves; it is found that sample 1 has a better shortwave response and higher quantum efficiency at short wavelengths. Combined with the band structure diagram of the transmission-mode GaAs/AlGaAs photocathode and the fitted performance parameters, we analyze the phenomenon. It is found that the transmission-mode GaAs/AlGaAs photocathode with variable Al component and various doping structure can form a two-stage built-in electric field, which improves the probability of shortwave response photoelectrons escaping to the vacuum. In conclusion, such a structure reduces the influence of back-interface recombination, improves the shortwave response of the transmission-mode photocathode.

    We report the effect of a thin GaN (2 nm) interlayer on the magnetotransport properties of AlInN/AlN/GaN-based heterostructures. Two samples were prepared (Sample A: AlInN/AlN/GaN and sample B: AlInN/GaN/AlN/GaN). Van der Pauw and Hall measurements were performed in the 1.9-300 K temperature range. While the Hall mobilities were similar at room temperature (RT), sample B had nearly twice as large Hall mobility as sample A at the lowest temperature; 679 and 889 cm{sup 2}/Vs at RT and 1460 and 3082 cm{sup 2}/Vs at 1.9 K for samples A and B. At 1.9-10 K, the longitudinal magnetoresistance was measured up to 9 T, in turn revealing Shubnikov-de Haas (SdH) oscillations. The carrier concentration, effective mass and quantum mobility of the two-dimensional electron gas (2DEG) were determined from SdH oscillations. At 1.9 K, the 2DEG concentration of sample B was nearly seven times larger than of sample A (1.67 x 10{sup 13}/cm{sup 2} vs. 0.24 x 10{sup 13}/cm{sup 2}). On the contrary, the quantum mobility was changed adversely nearly three times (sample B 2500 cm{sup 2}/Vs and sample A 970 cm{sup 2}/Vs). The increase of the 2DEG concentration was attributed to the existence of the GaN interlayer, which has strengthened the spontaneous polarization difference between the AlInN and GaN layers of the heterostructure. Hence, the stronger electric field at the 2DEG region bent the conduction band profile downwards and consequently the quantum mobility decreased due to the increased interface roughness scattering.

    2011-01-01

    Deformation processed metal-metal composites (DMMC’s) are composites formed by mechanical working (i.e., rolling, swaging, or wire drawing) of two-phase, ductile metal mixtures. Since both the matrix and reinforcing phase are ductile metals, the composites can be heavily deformed to reduce the thickness and spacing of the two phases. Recent studies have shown that heavily drawn DMMCs can achieve anomalously high strength and outstanding combinations of strength and conductivity. In this study, Al-Fe wire composite with 0.07, 0.1, and 0.2 volume fractions of Fe filaments and Al-Ca wire composite with 0.03, 0.06, and 0.09 volume fractions of Ca filaments were produced in situ, and their mechanical properties were measured as a function of deformation true strain. The Al-Fe composites displayed limited deformation of the Fe phase even at high true strains, resulting in little strengthening effect in those composites. Al-9vol%Ca wire was deformed to a deformation true strain of 13.76. The resulting Ca second-phase filaments were deformed to thicknesses on the order of one micrometer. The ultimate tensile strength increased exponentially with increasing deformation true strain, reaching a value of 197 MPa at a true strain of 13.76. This value is 2.5 times higher than the value predicted by the rule of mixtures. A quantitative relationship between UTS and deformation true strain was determined. X-ray diffraction data on transformation of Al + Ca microstructures to Al + various Al-Ca intermetallic compounds were obtained at the Advanced Photon Source at Argonne National Laboratory. Electrical conductivity was measured over a range of true strains and post-deformation heat treatment schedules.

    Full Text Available Gullettes kulturwissenschaftliche Untersuchung Aged by Culture ist wie bereits ihre zwei vorangehenden Werke, die sich mit Altern beschäftigen – Safe at Last in the Middle Years: The Invention of the Midlife Progress Novel (1988 und Declining to Decline. Cultural Combat and the Politics of the Middle (1997 –, von großem persönlichen Engagement und durch ein politisches Anliegen motiviert. Sowohl die Dringlichkeit als auch der Widerstand, den Gullette, die sich als „age critic“ definiert, als moralische und politische Notwendigkeit postuliert, werden in der Zweiteilung der Abhandlung angesprochen: „Cultural Urgencies“ und „Theorizing Age Resistantly“. Während Gullette den Begriff „aged by culture“ bereits in Declining to Decline einführt, stellt sie ihn nun in den Mittelpunkt ihrer Untersuchung. Das Buch ist einerseits einer gesellschaftspolitischen Analyse der USA gewidmet, andererseits wird eine Theorie des Widerstands gegenüber Altersdiskriminierung entwickelt.Gullette’s cultural studies based analysis Aged by Culture is marked by great personal engagement and motivated by political goals, as are her two previous texts that deal with aging: Safe at Last in the Middle Years: The Invention of the Midlife Progress Novel (1988 and Declining to Decline. Cultural Combat and the Politics of the Middle (1997. Both the urgency as well as the resistance that Gullette, who defines herself as an “age critic,” postulates as a moral and political necessity are addressed in the two parts of the text: “Cultural Urgencies” and “Theorizing Age Resistantly.” Whereas Gullette had already introduced the concept “aged by culture” in Declining to Decline, now she has placed it at the center of her examination. On the one hand, the book is devoted to a sociopolitical analysis of the USA; on the other hand, it develops a theory of resistance to age discrimination.

    Full Text Available El entendimiento completo del proceso de adsorción y posterior oxidación de moléculas de CO en platino es de fundamental importancia para el desarrollo de celdas de combustible poliméricas que operan a baja temperatura. En este trabajo se presenta una revisión de las cinco estrategias experimentales más importantes en la búsqueda de mejorar la tolerancia al CO: disminución del potencial de inicio de la reacción de oxidación, reducción de la cantidad de CO adsorbido, utilización de pequeñas cantidades de oxígeno en la corriente de alimentación al ánodo, aumento de la temperatura de operación y limpieza del CO a la entrada. Aunque se han desarrollado catalizadores bastante promisorios (PtMo y PdAu, todavía se sigue considerando a la mezcla Pt-Ru como el catalizador anódico más eficiente para combustibles que contienen 10 ppm de CO o más. La estrategia de inyectar oxígeno al ánodo parece promisoria pero requiere el desarrollo de nuevas membranas más resistentes y de la implementación de condiciones más seguras de operación de la celda. El diseño estructural de ánodos especiales con múltiples capas soportando catalizadores específicos para cada tipo de combustible puede ser una estrategia muy atractiva.

    In der vorliegenden Arbeit stellen wir ein neues Modell zur Kopplung des Tumormasseeffektes an die, der Wachstumsmodellierung unterliegende, anisotrope Reaktionsdiffusionsgleichung vor. Die Gleichung wird auf einem hochaufgelösten Voxelgitter diskretisiert. Eine Modellierung der Anisotropie des Diffusionsprozesses ermöglicht die Integration von Diffusions-Tensor-Bildgebungsdaten. Die raumfordernde Wirkung des Tumors wird als parametrisches Bildregistrierproblem aufgefasst. Hierbei wird die resultierende Verteilung der Tumorzellkonzentration in die zu optimierende Zielfunktion integriert. Erste qualitative Ergebnisse zeigen, dass eine Minimierung der aufgestellten Zielfunktion zu einer plausiblen Modellierung des Masseeffektes führt.

    Highlights: • Nanocrystalline powders of FeAl have been obtained from the Fe{sub 81}Al{sub 19} ribbon produced by melt spinning. • The method allows the obtainment of a FeAl solid solution from the starting process. • The microstructure and magnetic properties of the powders were investigated. • Composites with a magnetostriction of 45 ppm have been obtained. - Abstract: Ribbons of composition Fe{sub 81}Al{sub 19} obtained by the melt spinning method have been used to yield powder by mechanical milling. Using this method, a rapid nanocrystallization and a FeAl solid solution phase was obtained from the start of the process. The microstructural and magnetic properties as well as the XRD patterns of the powders were studied in function of the milling time. Grain refinement and an increase of the coercive field were the main transformations resulting from increasing the milling time. Two sets of magnetostrictive composites were produced from the 100 h-milled powder. In one of them polyester was used as matrix and in the other one silicone. In the case of the silicone composites cured in a magnetic field of 140 mT in the longitudinal direction a saturation magnetostriction as high as 45 ppm was obtained.

  17. Millimeter distance effects of surface plasmon polaritons in electroformed Al-Al2O3-Ag diodes

    Science.gov (United States)

    Hickmott, T. W.

    2017-02-01

    Electroforming of metal-insulator-metal diodes is a soft dielectric breakdown that changes the high resistance of as-prepared diodes to a low resistance state. Electroforming of Al-Al2O3-metal diodes with anodic Al2O3 results in voltage-controlled negative resistance in the current-voltage (I-V) characteristics, electroluminescence (EL), and electron emission into vacuum (EM). EL is due to electrons injected at the Al-Al2O3 interface combining with radiative defects in Al2O3. Surface plasmon polaritons (SPPs) are electromagnetic waves that can be excited by photons or electrons. SPPs are confined to a metal-dielectric interface, cause large electric fields in the metal and dielectric, and have ranges of micrometers. The temperature dependence of I-V curves, EL, and EM of a group of electroformed Al-Al2O3-Ag diodes with Al2O3 thicknesses between 12 nm and 20 nm, group A, was measured between 200 K and 300 K. After a sequence of temperature measurements, the Al-Al2O3-Ag diodes, the Al-Al2O3 regions between diodes, and portions of the Ag on the glass region that provides contacts to the diodes are darkened. The range of darkening is >7 mm in a diode with 12 nm of Al2O3 and 2.0-3.5 mm in diodes with Al2O3 thicknesses between 14 nm and 20 nm. Darkening is attributed to the occurrence of SPPs generated by EL photons at the Ag-Al2O3 and Al-Al2O3 interfaces. The results are compared to a second group of Al-Al2O3-Ag diodes with identical Al2O3 thicknesses, group B, that were prepared in the same way as the diodes of group A except for a difference in the deposition of Al films for the two groups. Al-Al2O3-Ag diodes of group B exhibit enhanced EL, which is attributed to spontaneous emission of recombination centers in Al2O3 being enhanced by large electromagnetic fields that are due to SPPs that are generated by EL photons.

    Mechanically alloyed Al with immiscible elements such as Nb can lead to a uniform distribution of nanoscaled precipitates which are highly stable compared to conventional alloying and with excellent interface, resulting in significant increase in strength without problems associated with nano ceramic particles in metal matrix composites. Although immiscible, Nb can be alloyed with Al through mechanical milling, forming trialuminide (Al3Nb), either directly or upon subsequent precipitation, which possesses high strength, stiffness and stability at elevated temperatures. In the present study, Al-5 at.% Nb supersaturated solid solution was achieved after prolonged ball milling and nano Al3Nb precipitates were formed during subsequent ageing at 530°C. The Al-Al3Nb powder was consolidated by equal channel angular pressing (ECAP) at 400°C, resulting in a fully dense material with a uniform distribution of nanoscaled Al3Nb precipitates in the Al matrix.

    In this study, the fabrication and structural characterization of amorphous/nanocrystalline Al{sub 9}FeNi/Al{sub 3}Ti phase has been performed. In this regards, milling and annealing processes were applied on Al{sub 80}Fe{sub 10}Ti{sub 5}Ni{sub 5} (at. %) powder mixture for different periods of time. The prepared samples were characterized using X-ray diffraction (XRD), scanning and transmission electron microscopy (SEM and TEM) and differential scanning calorimetery (DSC). According to the results, supersaturated solid solution, nanocrystalline Al{sub 9}FeNi/Al{sub 3}Ti (with average crystallite size of about 7 nm) and amorphous phases indicated three different microstructures which can be formed in Al{sub 80}Fe{sub 10}Ti{sub 5}Ni{sub 5} system during milling process. The formed supersaturated solid solution and amorphous phases were unstable and transformed to Al{sub 9}FeNi/Al{sub 3}Ti intermetallic compound during annealing process.

    2016-01-01

    Astronomical observations in the Far Ultraviolet (FUV) spectral region are some of the more challenging due to the very distant and faint objects that are typically searched for in cosmic origin studies such as origin of large scale structure, the formation, evolution, and age of galaxies and the origin of stellar and planetary systems. These challenges are driving the need to improve the performance of optical coatings over a wide spectral range that would increase reflectance in mirrors and reduced absorption in dielectric filters used in optical telescope for FUV observations. This paper will present recent advances in reflectance performance for Al+AlF3 mirrors optimized for Lyman-alpha wavelength by performing the deposition of the AlF3 overcoat at elevated substrate temperatures.

    2017-11-01

    Based on their highly sophisticated crossed-beam experimental studies of the Al + CO2 → AlO + CO reaction, Honma and Hirata have directly challenged the results of earlier theoretical studies of this system. We report high level theoretical studies of this system. It is shown that, consistent with Honma-Hirata experimental conclusions, the previous theoretical prediction of a substantial barrier height for this reaction was incorrect. However, for the structures of the possible intermediates, in agreement with the 1992 theoretical study of Sakai, we find striking disagreement with the experimental conclusion that the O-C-O moiety is nearly linear. The energies of the three entrance channel intermediates lie 14.4, 15.2, and 16.4 kcal mol-1 below separated Al + CO2.

    2016-12-15

    Optical properties and carrier dynamics of an AlGaN layer with an AlN content of 20% have been studied using time-resolved photoluminescence (TR-PL). Despite the high density of defects due to the relatively high AlN content, an intense PL emission from the sample has been detected. Low-temperature PL spectra exhibit several features, accompanied by a strong emission-wavelength dependence of the PL decay time. A significant red-shift of more than 200 meV from the band edge is recorded for the PL emission from localized states. Temperature-dependent PL spectra of the sample are dominated by the emission from localized states and, furthermore, show a relatively slight decrease by almost an order of magnitude with increasing temperature from 45 to 300 K. Our observations indicate strong, spatial localization effects of carriers, resulting in an increase in the radiative recombination rate.

    The increasing use of power electronics, such as high-current semiconductor devices and modules, within space vehicles is driving the need to develop specialty thermal management materials in both the packaging of these discrete devices and the packaging of modules consisting of these device arrays. Developed by Applied Nanotech, Inc. (ANI), CarbAl heat transfer material is uniquely characterized by its low density, high thermal diffusivity, and high thermal conductivity. Its coefficient of thermal expansion (CTE) is similar to most power electronic materials, making it an effective base plate substrate for state-of-the-art silicon carbide (SiC) super junction transistors. The material currently is being used to optimize hybrid vehicle inverter packaging. Adapting CarbAl-based substrates to space applications was a major focus of the SBIR project work. In Phase I, ANI completed modeling and experimentation to validate its deployment in a space environment. Key parameters related to cryogenic temperature scaling of CTE, thermal conductivity, and mechanical strength. In Phase II, the company concentrated on improving heat sinks and thermally conductive circuit boards for power electronic applications.

Es ist das Verdienst von Rainer Herrn, mit dem hier angezeigten Buch die Frühgeschichte von Transgender auf- und nachgezeichnet zu haben, die sich in Berlin im ersten Drittel des 20. Jahrhunderts zugetragen hat. Verknüpft ist diese Geschichte vor allem mit dem Namen Magnus Hirschfeld, der bislang in erster Linie als Vorkämpfer für die Entkrimininalisierung der Homosexualität wahrgenommen wurde. Einen passenderen Titel als Schnittmuster des Geschlechts hätte der Autor für sein Buch nicht finden können.Every history has a prehistory. Rainer Herrn has produced an accomplished work that records and traces the early history of transgendered people in Berlin during the first third of the twentieth century. This history is particularly connected to the name Magnus Hirschfeld, who, till now, has been primarily perceived as a pioneering campaigner for the decriminalization of homosexuality. The author could not have found a more appropriate title for his book than Patterns of Gender (Schnittmuster des Geschlechts.

    Full Text Available El artículo defiende que existe un derecho subjetivo al arte fundamentado en la autonomía del arte, que lo diferencia de otras formas expresivas; en la capacidad de apropiación subjetiva del arte exclusivamente por parte de los seres humanos; en las posibilidades del arte para la construcción de formas de expresión varias; y en el potencial uso del arte en políticas públicas propias de los sistemas democráticos, que ayudaría al derecho a la paz y a la reconciliación, así como formas alternativas de reparación y rehabilitación en sociedad. La exclusividad de la relación del hombre con el arte fundamentaría su objetivación y, por ello, lo convertiría en un derecho jurídicamente exigible.

    Full Text Available En las últimas décadas hemos presenciado un cambio dinámico en la naturaleza de las relaciones. El marketing transaccional, donde los intereses individuales de las partes priman sobre los beneficios conjuntos, ha dado paso al marketing de relaciones, cuyo objetivo consiste en maximizar el valor que ambas partes obtienen de la relación en la que están inmersas. El establecimiento, desarrollo y mantenimiento de relaciones orientadas al largo plazo representa un paso decisivo para alcanzar una ventaja competitiva. Los clientes leales constituyen una de las principales fuentes de rentabilidad de las empresas y se convierten en su activo más valioso. La evolución de los escenarios competitivos justifica que la naturaleza de las relaciones entre los miembros del canal de distribución se encuentre sometida a un continuo proceso de cambio. El incremento en la competencia y los cambios en los comportamientos de los consumidores finales son factores que están modificando la situación tradicional de los canales de distribución.

    Full Text Available Aunque sabemos que en el Islam la mujer, en términos generales, estaba excluida del poder, encontramos haciendo un breve repaso en el Islam medieval que muchas mujeres desempeñaron un papel político de cierta importancia, de manera especial, entre las dinastías nacidas en Asia Central. Asimismo, fueron también numerosas las mujeres que ejercieron una notable influencia en el gobierno tanto a través de sus maridos como actuando como regentes de sus hijos en al-Andalus y en el norte de África. Es por tanto a estas mujeres que ejercieron el poder entre los musulmanes a las que dedicamos estas líneas.Although it is known that in the Islamic worid, women in general, couldn't access to power, we find that looking back at the middie age period, women didn't only particípate in military campaigns, but as well they played their role of certain importance in politics, specially among dynasties coming from Central Asia. At the same time, there were a number of women who had influence in the political power, both acting through their husbands, and as regents of their children in Al - Andalus, and in North África. Therefore, we dedícate the following text to these women with political power among the Muslims.

    La Sociedad Colombiana de Historia de la Medicina, a través de su Junta Directiva, ha encargado al doctor Efraim Otero Ruiz y a quien les habla para rendir homenaje al Profesor Ernesto Andrade Valderrama. Honorífico pero difícil encargo, que he tomado con el mayor de los gustos y con el temor de no poder siquiera dibujar la bella parábola trazada por su vida hasta el presente. Aunque debo referirme fundamentalmente a su vida profesional, no puedo dejar de articular lo científico con lo humano.

    Ernesto Andrade Valderrama nació en esta ciudad de Bogotá, de una familia que reunió las mejores virtudes Santafereñas y Santandereanas; su padre Eugenio Andrade Suescún fue Gobernador de Santander durante el gobierno del General Ramón González Valencia y Secretario (Ministro del Tesoro durante la administración del Presidente Jorge Holguín. Su familia fue formada bajo principios cristianos orientados al servicio de sus semejantes. Por ello no es de extrañarnos que de los 17 hijos de Don Eugenio Andrade, cinco se hubiesen dedicado al sacerdocio, 3 de ellos jesuitas, uno de los cuales, Bernardo, fue misionero en la China y quien lastimosamente falleció ahogado al tratar de rescatar a un niño durante el naufragio del barco en que regresaba del oriente, frente a las costas italianas.

    Proviene pues, de una familia de tradición conservadora (los Andrade que se complementó con la liberal (los Valderrama -su madre fue Doña Inés Valderrama Ordóñez-. En el seno de esta familia destinada al servicio de los demás crece Ernesto Andrade Valderrama, quien estudia medicina en la Universidad Nacional de Colombia, donde recibió su grado de Doctor en Medicina y Cirugía en 1942 con la Tesis “Rectosigmoidoscopia y Observaciones sobre Cirugía Ano-Rectal”, con la cual mostraba su clara inclinación por la cirugía. Así, en 1943 por concurso gana el título de Jefe de clínica Quirúrgica del Hospital de San Juan de Dios de Bogot

    Effect of Al and AlP particles on the microstructure of near eutectic Mn-Si alloy (Mn-30 wt.%Si) was studied by Electron Probe Micro-analyzer (EPMA) and Differential Scanning Calorimeter (DSC). Crystal lattice correspondence analyses show that both Al and AlP have good lattice matching coherence relationships with MnSi phase, and the addition of Al and AlP particles results in an abnormal eutectic structure, i.e. the eutectic constitution MnSi and Mn{sub 5}Si{sub 3} precipitate separately: MnSi precipitates firstly, and then the Mn{sub 5}Si{sub 3} phase.

    Science.gov (United States)

    Hibbard, Stephen

    2003-06-01

    Lilienfeld, Wood, and Garb (2000) published a largely negative critique of the validity and reliability of projective methods, concentrating on the Comprehensive System for the Rorschach (Exner, 1993), 3 systems for coding the Thematic Apperception Test (TAT; Murray, 1943) cards, and human figure drawings. This article is an effort to document and correct what I perceive as errors of omission and commission in the Lilienfeld et al. article. When projective measures are viewed in the light of these corrections, the evidence for the validity and clinical usefulness of the Rorschach and TAT methods is more robust than Lilienfeld et al. represented.

    The wetting behaviour of aluminium on basal planes of {alpha}-SiC single crystals was investigated between 1000 and 1200 K by the sessile drop technique in high vacuum. The experiments were focused on wetting kinetics to determine the mechanisms controlling the rate of spreading and to identify all the characteristic contact angles formed during an isothermal experiment. Pure Al and Al alloys with silicon, copper and tin were studied. In some experiments SiC substrates covered by a silica layer 10-50 nm thick were used. (orig.)

    Positron annihilation in structural vacancies in B2 Al-rich NiAl alloys is studied theoretically. For this purpose we use the atomic superposition method combined with molecular dynamics employed for relaxations of random vacancy configurations. We found that the defect lifetime decreases with the increasing Ni vacancy concentration. Calculated positron lifetimes are discussed in terms of the 'vacancy-superstructure' effect and compared with experimental positron lifetime data available.

    Highly efficient emitters of polarized electrons based on the InAlGaAs/AlGaAs superlattice give an optimistic prognosis to explorations of such structures as the sources for accelerators. A new set of these SL structures with minimized conduction band offset was designed and recently tested. A new technology of surface protection in MBE growth leads to a significantly reduced heat-cleaning temperature. At these lowered cleaning temperatures, the thermal degradation of the working structure parameters is avoided. As a result a polarization P of up to 91% at corresponding quantum efficiency (QE) of 0.3% was achieved at room temperature.

    In this Letter we report on the exploration of axial metal/semiconductor (Al/Ge) nanowire heterostructures with abrupt interfaces. The formation process is enabled by a thermal induced exchange reaction between the vapor-liquid-solid grown Ge nanowire and Al contact pads due to the substantially different diffusion behavior of Ge in Al and vice versa. Temperature-dependent I-V measurements revealed the metallic properties of the crystalline Al nanowire segments with a maximum current carrying capacity of about 0.8 MA/cm(2). Transmission electron microscopy (TEM) characterization has confirmed both the composition and crystalline nature of the pure Al nanowire segments. A very sharp interface between the ⟨111⟩ oriented Ge nanowire and the reacted Al part was observed with a Schottky barrier height of 361 meV. To demonstrate the potential of this approach, a monolithic Al/Ge/Al heterostructure was used to fabricate a novel impact ionization device.

    Full Text Available The effects of different amounts of added Al, ranging from 1 % to 9 %, on the microstructure and properties of Mg-Al binary alloys were investigated. The results showed that when the amount of added Al is less than 5%, the grain size of the Mg-Al binary alloys decreases dramatically from 3 097 μm to 151 μm with increasing addition of Al. Further addition of Al up to 9% makes the grain size decrease slowly to 111 μm. The α-Mg dendrite arms are also refined. Increasing the amount of added Al decreases the hot cracking susceptibility of the Mg-Al binary alloys remarkably, and enhances the micro-hardness of the α-Mg matrix.

    Full Text Available Al-Humaydî is one of the figures of hadist from Mecca area. He belongs to the main generation as the follower of tâbi`în who lived and gathered with one of the chiefs of fiqh Madzhab, which is Muhammad bin Idris al-Syâfi’î. Thus, al-Humaydî belongs to the earliest ulama of madzhab Syâfi’î. In the knowledge of Hadist, al-Humaydî and his Musnad book becomes the part of the early musnad kitab even earlier than the most popular musnad book by Ahmad bin Hanbal. Although musnad book of al-Humaydî is not the most popular book but this book belongs to the most important musnad Hadist book. Al-Bukhârî as a popular Mukharrij takes Hadist from al-Humaydî with least corrections. Al-Humaydî is the teacher of al-Bukhârî in Hadist and also for fiqh. This proves that the figure of al-Humaydî as the reader of hadist is believable. But, not all the Hadist in the musnad al-Humaydî is shahîh/true. Some of the munqathi’ Hadist which is told by al-Humaydî and al-Bukhârî knew this. This writing is trying to partly introduce and give some notes of al-Humaydî and his musnad. Therefore we will know one of the ancient Hadist books and know the figures of the one who arrange and understand the musnad Hadist book. Kata Kunci:Al-Humaydî , Musnad, Hadits, al-Bukhârî

The results show that the Al doped graphene has strong chemisorption of CO molecule by forming Al-CO bond, where CO onto intrinsic graphene remains weak physisorption. Furthermore, the enhancement of CO sensitivity in the Al doped graphene is determined by a large electrical conductivity change after adsorption, where CO absorption leads to increase of elect...

  9. Advanced life support (ALS) instructors experience of ALS education in Western Australia: a qualitative exploratory research study.

    Taplin, John; McConigley, Ruth

    2015-04-01

    When cardiac arrest occurs, timely competent advanced life support (ALS) interventions by nursing staff can influence patient outcomes. Ongoing ALS education influences maintenance of competency and avoids skill decay. To explore the methods of ALS education delivery for nurses in the workplace; describe the issues relating to maintaining ALS competency; explore ALS competency decay for nurses and develop recommendations for the provision of continuing ALS education. A qualitative exploratory design was used to study ALS education provision in the workplace. Data were collected from ALS nurse experts in Western Australia by face-to-face and phone interviews. Semi-structured interviews were conducted and organised around a set of predetermined questions. Two major themes were identified; the first theme Demand and Supply describes the increasing demand for ALS education for nurses and the challenges with providing timely cost effective traditional face-to-face ALS education. The second theme, Choosing The Best Education Options describes new ways to provide ALS education using emerging technologies. The study suggested that using e-learning methods would assist with educating the maximum amount of nurses in a timely manner and e-learning and teleconferencing offer opportunities to reach nurses in distant locations. Delivering ALS education more frequently than annually would increase skills maintenance and lessen skill decay. Further research is required to explore which blended e-learning model is best suited to ALS education. Copyright © 2014 Elsevier Ltd. All rights reserved.

The word of Radha'ah in the Qur’an is used for two meaning: first, as one reason for marriage forbidden due to foster sister (QS. al-Nisa’: 23, and second, as the activity of breastfeeding for the mother to her baby, in which the milk becomes the main food for babies, especially the first six months of birth, and highly recommended it be given to infants until two years old (Surah al-Baqarah: 233. Feeding activity is a series of pregnancy, childbirth and infant care. The fourth activity has been established by Allah to each of women as the nature  and the trust as well. All of these gifts, recognized by the Qur'an as a condition that is very exhausting and burdensome to mother, but noble in the sight of Allah. Therefore, children must be grateful, respectful and dutiful to his parents, so that they can remember the good, service, and the struggle of his parents (Luqman: 14, al-Ahqaf: 15 Radha'ah as the main activity of the mother after the birth of her baby, bring benefits to both mother and baby. Breastfeeding can build psychological situation of calm and full of affection between mother and child. However, in practice, interest of mother in giving breastfeed declined, whereas the Qur’an has set the terms of breastfeeding, obligations and rights of mothers to breastfeed, breastfeeding and weaning time limit. The father should provide to mother during breastfeeding or find a woman to give breastfeeding and these conditions causes mahram. In addition, breast-feeding should be intended for the worship of Allah so the mother had the pleasure and reward from Him.

    In this work, a north american bentonite was pillared with Al and Al/Fe, creating the Al-PILC and Al-Fe-PILC, respectively. Then the Pd was impregnated in the materials, generating Pd-Al-PILC and Pd-Al-Fe-PILC, respectively. The samples were characterized by X-ray diffraction, differential thermal analysis and thermogravimetric and N{sub 2} adsorption at 77 K to determine the specific surface area by BET method (Brunauer - Emmett - Teller). There was an increase in the basal spacing of bentonite from 12.4Å in the original sample to 17.81Å in the Al-Fe-PILC, 17.20Å in Pd-Al-PILC and 17.05Å in the Pd-Al-Fe-PILC. The specific surface area increased from 19.05m{sup 2}/g in the original sample to 173.49m{sup 2}/g in Al-Fe-PILC, 101.31m{sup 2}/g to Pd-Al-PILC and 92m{sup 2}/g in Pd-Al-Fe-PILC.
