    Full Text Available Existen bastantes evidencias para vincular la cultura del vino con el entorno y el desarrollo sostenible. En primer lugar, destaca que la cultura del vino es el reflejo del aprovechamiento vitivinícola del medio y, por tanto, refleja su efecto sobre el desarrollo social y económico de las regiones, lo que es plausible a través del devenir histórico de las mismas. Más recientemente, el aprovechamiento de la cultura del vino para su explotación a través de las experiencias enoturísticas, ha supuesto una revalorización de muchos territorios, impulsando el desarrollo social y económico. La cultura del vino no es sólo el eje temático de la actividad enoturística, sino que es su base y pilar esencial, por tanto, se relaciona directamente con la sostenibilidad ambiental, económica y social que subyace tras el enoturismo. Además, es importante tener en cuenta que gran parte de la importancia de la cultura del vino se centra en las señas de entidad asociadas a cada territorio, que aportan características distintivas y singulares, contribuyendo a la sostenibilidad cultural. En España, ACEVIN y el Rutas del Vino de España son claros ejemplos de como la cultura del vino es un motor del desarrollo sostenible de las regiones vitivinícolas.

    Full Text Available En primer lugar se describe el mercado del vino y posteriormente se elabora un perfil para el consumidor de vino orgánico, siendo la base de esta caracterización la revisión de fuentes secundarias de información. Además, se realizaron entrevistas con especialistas del área vitivinícola, reuniones con representantes de algunas viñas regionales, visitas a terreno y la aplicación de un cuestionario para describir el nivel de conocimiento y gustos que tienen los consumidores regionales referentes a vinos orgánicos, precios, conocimiento de marcas, canales de distribución y, por último, motivos de preferencias para probar un nuevo vino. Luego de estudiar una muestra representativa de la población de la región del Bío-Bío, orientada a mayores de 18 años, pertenecientes a los estratos socioeconómicos ABC1, C2, C3, se está en condiciones de dar a conocer un perfil de consumidor para este tipo de vino, concluyendo que no existe una diferencia notoria entre el consumidor de vino orgánico y tradicional. This study aims to describe the average consumer's profile for organic wine in region VIII. This type of wine is produced under strict control of chemical components through out its entire production process. The first part of this work presents a general description of the wine industry using secondary sources. In addition, in-depth interviews with wine experts were developed and an structured questionnaire was applied for descriptive variables in arder to describe variables such as tastes and preferences, brand awareness, prices, distribution channels and finally perceptions on the potential for organic wines. Given the sample applied to the population of the region over 18 years old, belonging to the social stratum ABC1, C2, and C3, it is concluded that no significant differences exist between average consumer of tradicional and organic wines.

  8. El Chicamocha: Río del Vino de Gran Altura

    Directory of Open Access Journals (Sweden)

    Marco Quijano Rico

    2007-10-01

    Full Text Available Nuestro proyecto de viticultura tropical de calidad se inició en la Loma de Puntalarga, en el Valle del Sol en 1982. Los viñedos están situados a gran altura entre los 2400 y los 2600 metros, en terrenos inclinados, consuelos de buena vocación vitícola, bastante brillo solar, calor diurno, frío nocturno y déficit hídrico; condiciones necesarias para producir uvas de alta calidad para vinificación. El cultivo se viene extendiendo desde los años noventa por diversos lugares. En este proceso el río Chicamocha parece ejercer un efecto similar al de otros ríos del vino. Entre los ríos más representativos del hábitat tradicional de las variedades cultivadas en la región, Riesling blanca y Pinot noir, están respectivamente el Rin en Alemania y el Saona en Francia. La distribución geográfica del desarrollo vitícola sigue la dirección del curso del río Chicamocha y prácticamente recubre a la de en claves poblacionales que influenciaba el centro religioso de Sogamoso, antes de la llegada de los españoles en 1537. Algo similar sucede con la distribución de cepas descendientes de la variedad Mission, probablemente introducida por jesuitas a Firavitoba en el siglo XVII. Parece que estos fenómenos podrían relacionarse en menor o mayor grado con la historia geológica regional, en particular la del río Chicamocha. Su conocimiento puede proporcionar valiosas claves sobre los fundamentos del “terroir” y contribuir a acrecentar el carisma, asentado en la calidad, que ya revela el vino regional.

    Full Text Available En este artículo se exponen las vicisitudes por las que ha atravesado el vino de Cariñena para su comercialización desde el siglo pasado. Comienza con el éxito y los altos precios del vino conseguidos por la demanda francesa, tras la invasión filoxérica del país vecino, favorecidos también por la inauguración del ferrocarril de vía estrecha Zaragoza-Cariñena y seguidos de la crisis de superproducción y consiguiente descenso de los precios tras finalizar el Tratado de Comercio con Francia. Luego se explica la lenta recuperación a lo largo de este siglo, se facilitan las cantidades exportadas en el último cuarto del mismo, para analizar de forma más exhaustiva la situación del mercado exterior en la actualidad, donde el comercio europeo ha vuelto a ser el más importante y de modo especial el de la Unión Europea.In this article the different mishaps that the Cariñena wine has undergone to be commercialized since the last century are shown. The study begins with the success and the high price of the wine, due to the French demand, after the phylloxera invasión in the neighbouring country, also favoured by the opening of the narrow-gauge railway Zaragoza-Cariñena, and followed by the superproduction crises and the subsequent fall of the prices after the end of the Commercial Treaty with France. Afterwards, we explain the slow recovery along this century, giving the exported quantities in the last quarter of the century, and then analyzing more thoroughiy the situation of the foreign market nowadays, since the European trade has regained importance, specially the one in the European Union.

    2007-01-01

    Full Text Available Después de varias décadas del asentamiento de la cultura española en América se realizaron viajes trasatlánticos en busca de tesoros y recompensas por las conquistas de las Indias occidentales, entre las que se puede encontrar la riqueza de la fauna y flora. Así como algunas plantas fueron llevadas hacia la península, de la misma forma se trajeron otras, junto con sus derivados y materias procesadas, que hacían parte de la dieta fundamental de la cultura mediterránea. Una de ellas fue el vino. Los numerosos relatos de viajes, las cartas de navegación y los diarios de abordo, nos suministran una valiosa información para rastrear la procedencia de los productos de embarque, pero sobre todo el comercio y destino de algunos; en especial, del vino. En esta ponencia se tendrá en cuenta, en su orden, la producción; el transporte; el contrabando; y las formas de introducción y comercialización al interior del territorio, todo esto visto a partir de los reportes hechos en las aduanas a los caldos legales e ilegales que contribuyeron a generar la expansión de la cultura del vino en la Nueva Granada para el período colonial.

    2012-12-01

    Full Text Available Entre las modalidades más importantes del denominado turismo agrícola está el enoturismo o “turismo vitivinícola”, su principal objetivo se centra en el descubrimiento de los espacios vitícolas y las distintas connotaciones paisajísticas y etnográficas que ello conlleva, así como la consolidación de un sistema productivo local que incluye una red de ciudades con igual orientación productiva. El presente artículo tiene como objetivo estudiar las transformaciones territoriales derivadas de esta actividad productiva que no se limita al sector primario sino que ha incorporado elementos de terciarización del espacio agrícola que poco tienen que ver con el tradicional uso dedicado a la obtención de vino, de hecho han aparecido innovaciones reflejadas en la estética de las bodegas, creación de museos del vino, visitas a empresas, alojamientos, restaurantes o visitas a espacios culturales próximos. Como muestra tangible de esta realidad transformadora del paisaje y la economía local estudiaremos las actuales rutas del vino de la Comunidad de Murcia: Bullas, Jumilla y Yecla.

    Full Text Available En Uruguay existe un creciente consumo de drogas cuyas consecuencias negativas son visibles en los siniestros laborales, de tránsito y en el recrudecimiento de la violencia doméstica y delictiva. Este tema es considerado asunto de Estado y se entiende el alcohol como la primera droga de inicio (incluye la ingesta de vino. Nos interesa analizar el vínculo entre medicina y moral que, desde el Novecientos, ha pautado la relación del consumo de alcohol entre lo «saludable» o lo «excesivo». En esa atmósfera de creciente higienismo se desarrolló, sin embargo, una industria vitivinícola con éxito. En este artículo buscamos desnaturalizar los discursos médicos como construcción histórica y sus consecuencias en el cuerpo de los alcohólicos en espacios de reclusión (hospitales y cárceles y en la sociedad del Montevideo en el Novecientos.

  1. El Rioja, un vino apenas centenario

    Tomás Franco Aliaga

    1992-01-01

    Full Text Available Del vino rioja se ha apurado casi hasta la última página a través de nunnerosos libros e innumerables artículos. Pero siempre es posible un nuevo enfoque, un paladeo subjetivo de las fuentes y de los datos que, al transmitirlo, permite conocer mejor un fenómeno complejo y de enorme repercusión económica en La Rioja. Aunque los textos y las cifras son absolutamente rigurosos, el estilo utilizado roza levemente la ortodoxia científica al incorporar alguna licencia poética, como si los vapores etílicos se hubieran rebelado contra la voluntad del autor. Algo similar parecía ocurrirle a Berceo, aunque sin duda con mejores logros literarios.

De ahí, que vista su importancia pretendemos analizar su función como bebida en las festividades religiosas y celebraciones; la jurisprudencia relativa a la propiedad, el cultivo y la elaboración del vino judío; y finalmente, mostrar cómo las comunidades sefardíes o sus individuos acceden a la tierra, cómo se trabajan estos viñedos y se genera una industria subsidiaria, a pesar de las diversas restricciones que se imponen desde una sociedad mayoristamente cristiana.The Hebrew communities of the Iberian peninsula, along the Middle Ages, developed a complex system for the cultivation, elaboration and trade of the wine, in agreement with religious prescriptions tied to the concept of purity. In reason to its importance, we will analyze its function like drink in the religious festivities and other celebrations; the jurisprudence relative to the property, cultivation and elaboration of the Jewish wine; and, finally, we will show how the sefardíes communities or their individuals consent to the earth, how these vineyards are worked and a subsidiary industry is generated, in spite of the diverse restrictions that are imposed from a society of Christian majority.

    Full Text Available La propuesta de que el paisaje del viñedo sea el complemento a la visita a la bodega, siendo esta el eje del turismo del vino, es el objetivo de este trabajo. Repasando los conceptos variables de patrimonio, llegamos al paisaje del viñedo como recurso, formando parte del patrimonio natural. Pero este no se puede desvincular de los otros aspectos patrimoniales, por lo que la cultura tradicional es el soporte de la tipología de paisaje que queremos proponer y que va contrastar con los nuevos paisajes del viñedo que surgen de las recientes técnicas en los cultivos y de la actual vitivicultura, emparejada con una moderna “cultura del vino”. El análisis de las diversas normativas, que salvaguardan el paisaje y la comprobación del escaso valor legal del paisaje del viñedo, es otro puntal de este trabajo que trata de unir paisaje con cultura tradicional como recursos del Turismo del Vino, integrados en las Rutas del Vino.

    Full Text Available El tipo de tecnología y el tipo de mercado de cada Denominación de Origen Protegida de vino (DOP se puede identificar a través de diferentes elementos. Utilizando como marco de referencia la teoría de los mundos de producción, puede dividirse el tipo de tecnología en especializada y estandarizada, considerando aspectos relacionados con el grado de genera lización del conocimiento y el nivel de automatización. El tipo de mercado puede dividirse en genérico y dedicado, tomando en consideración la predictibilidad de la demanda, en función del tamaño del mercado de destino y el nivel de personalización de la p roducción. Para identificar estas dimensiones en el sector del vino se ha propuesto una batería de indicadores y se ha analizado su utilidad , para seleccionar aquellos más adecuados. La superficie por bodega, concebida como la interacción del tamaño medio de la explotación vitícola y el número de viticultores por bodega, ofrece un alto potencial en la definición del eje de tipo de tecnología. Por su parte, el tipo de mercado puede ser caracterizado utilizando el tamaño medio de la marca de vino, como indica dor de segmentación de la producción.

    2010-09-01

    Full Text Available The effect of using mixed cultures of non-Saccharomyces and Saccharomyces cerevisiae yeasts in the physicochemical and sensory qualities of the wines were analyzed in this study. Based on growth curves, sugar consumption and glycerol production in synthetic must, Candida membranifaciens L1805 was selected from a group of four Candidas spp. isolates from Chile and Argentina. This yeast was subsequently used in combination with S. cerevisiae in Chardonnay must. A monoculture of S. cerevisiae was used as control. The wines fermented with mixed cultures had lower volatile acidity and ethanol concentration than the control. Furthermore, the chromatographic analysis showed that the wines from mixed cultures presented differences in the concentration of esters and propanol. These characteristics positively influenced the sensory qualities of the wines produced with mixed cultures, which was reflected in the preference for these wines by a panel of enologists. This study shows that the use of non-Saccharomyces yeasts could be a strategy to obtain distinctive wines using the native microorganisms from each winemaking area.En este estudio se analizó el efecto del uso de cultivos mixtos de levaduras no-Saccharomyces y Saccharomyces cerevisiae en las cualidades fisicoquímicas y sensoriales de los vinos. Candida membranifaciens L1805 fue elegida de un grupo de cuatro Candida spp. aisladas de Chile y Argentina, sobre la base de las curvas de crecimiento, el consumo de azúcar y la producción de glicerol en mosto sintético. Posteriormente, esta levadura fue usada en cultivo mixto con S. cerevisiae en mosto Chardonnay. Como control se utilizó un monocultivo de S. cerevisiae. Los vinos producidos por cultivos mixtos tuvieron menor acidez volátil y producción de etanol que los correspondientes al control.

Dentro de este descenso generalizado el más perjudicado ha sido el mercado de graneles dada la tendencia a consumir mejores calidades. No obstante hay unos determinados vinos que están en una situación precaria y que al contrario de los graneles tienen una gran calidad y sobre todo una marcada personalidad, son los llamados vinos de licor. Éstos a pesar de su larga tradición y debido a diversas causas (moda, poca rentabilidad,.. son poco conocidos y casi siempre ignorados hasta incluso por los profesionales del sector vitivinícola.

    Full Text Available Continuamente la industria vitivinícola se preocupa de la alta competitividad del sector, creando productos más sofisticados y de mayor calidad. Sin embargo, dejan de lado un punto relevante que es la división o segmentación del mercado, generando estrategias comerciales generalizadas y no desarrollando productos y estrategias de marketing específicas diferenciadoras para mercados con características distintas. La industria de los vinos debe estudiar más en profundidad cuáles son las necesidades y deseos de cada uno de los segmentos de consumidores, para otorgar una mezcla comercial especializada y direccionada a cada segmento. Éste es un estudio exploratorio que muestra las diferencias en las preferencias de consumo y en el comportamiento de compra que presentaron los grupos etarios de una muestra de 488 consumidores de vino de la ciudad de Chillán, Chile. Los resultados indicaron que existen diferencias en las preferencias y en el comportamiento de compra de bebidas alcohólicas, según la edad del consumidor. También existe una correlación positiva entre la razón de consumo “me gusta el vino por su sabor y olor” y las ocasiones preferentes de consumo de vino cotidiana (almuerzo o cena, formal (almuerzo o cena, barbacoas, reuniones familiares y en restaurantes. Esto muestra la importancia de que el sector vitivinícola desarrolle estrategias de comercialización para cada uno de estos segmentos y también priorice que el sabor y olor del producto es fundamental en este mercado.

    Full Text Available En este trabajo se estudia la importancia que el pan y el vino tuvieron en la alimentación cotidiana de los judíos a lo largo de la Antigüedad y la Edad Media, así como el lugar que estos productos ocupan en el culto judío del Templo y en la liturgia de algunas de las más importantes celebraciones religiosas de carácter familiar. Los judíos, como todos los demás pueblos de civilización mediterránea, han basado tradicionalmente su agricultura en la llamada tríada mediterránea —cereal, vid y olivo—, lo que se refleja en su alimentación cotidiana, que se sustenta, en buena medida, en el consumo de pan y vino. Del mismo modo, desde la Antigüedad tardía y hasta tiempos actuales, el pan y el vino son elementos fundamentales en la celebración familiar de algunas de las principales festividades del calendario litúrgico judío, en particular el Sábado (Shabat y la Pascua (Pésah.In this work is studied the importance that bread and wine had in the daily feeding of the Jews throughout the Antiquity and in the Middle Ages, as well as the role that these products played in the Jewish cult of the Temple and in the liturgy of some of the most important familiar religious celebrations. The Jews, like all the other peoples of Mediterranean civilization, have traditionally based their agriculture on the Mediterranean Triad —cereal, grapevine and olive tree—, that is reflected in their daily feeding, that sustains themselves, to a great extent, in bread and wine consumption. Thus, from the late Antiquity to now, bread and wine are fundamental elements in the family celebrations of some of the main festivities of the Jewish Liturgical Calendar, in particular, the Saturday (Shabat and the Passover (Pésah.

    Full Text Available In the Etnian region, during XVII and XIX centuries wine production begins to be made in a proto-industrial way. Great industries for wine production are built in these dates with a great technological and architectural specialization. Many of these constructions are in use today with good conservation state, but others are abandoned or ruined. In this paper the main characteristics of the "palmenti" and wine cellars that yet exist are analyzed. Architectural aspects are related with simple functionality aspects devoting special attention to the press machinery. The present state of this architectural patrimony and reasons to preserve and reuse it are discussed. Several ways and proposals to achieve this are defined at the end.

    En la región del Etna, entre los siglos XVII y XIX, la producción del vino empieza a hacerse de un modo protoindustrial. En tales fechas se construyen numerosas infraestructuras de grandes dimensiones para producir vino, denotando una gran especialización tecnológica y arquitectónica. Muchas de estas construcciones se usan aún hoy, manteniéndose en buen estado; otras, sin embargo, avanzan hacia el abandono y el deterioro. En el presente estudio se analizan las características principales de las bodegas y de los "palmentos" que han llegado hasta nosotros. Se relacionan los aspectos arquitectónicos con los puramente funcionales y se dedica una atención especial a la maquinaria de prensado. Se detalla al final el estado actual en el que se encuentra este patrimonio arquitectónico y se discuten las razones que hoy día animan a conservarlo y a volver a ponerlo en funcionamiento. Por último, se definen rápidamente los modos concretos y las propuestas para llevarlo a cabo.

    Full Text Available El turismo del vino posee potencial para colaborar en el desarrollo económico de las zonas rurales, ya que proporciona a la industria turística una serie de destinos adicionales y complementarios capaces de generar valor añadido a la región. Sin embargo, la industria del vino y la turística no van siempre de la mano. Las bodegas, que constituyen el elemento central del producto enoturístico, deben comprometerse en el desarrollo de este tipo de turismo. Pero, en general, el sector bodeguero está integrado por pequeñas empresas, muchas de ellas familiares, las cuales siguen una orientación producto más que una orientación relacional. Esta investigación analiza las percepciones que este tipo de bodegas asocian al esfuerzo que deben realizar para desarrollar turismo del vino.

Se definió la preparación de la fruta, las condiciones de fermentación requeridas y el tiempo necesario para la finalización del proceso fermentativo. Los resultados muestran que es factible obtener vinos de diferentes calidades según los estándares internacionales y porcentajes alcohólicos que van desde el 5 % hasta 17 % en V/V aproximadamente. Siendo posible seleccionar aquellas variantes con valores de porcentaje alcohólico entre 9 y 18 % en V/V (como estándar recomendado y que llenen exigencias como: acidez, sólidos solubles y otros parámetros recomendados para un vino. En nuestro caso, tenemos vinos de alto porcentaje alcohólico como los de papaya y nancite, o de bajos porcentajes de alcohol como granadilla, calala y otros. Vinos de mango, calala y papaya, se deberá tener mucho cuidado durante su producción ya que fácilmente se acidulan durante el proceso. Este estudio aporta una manera útil de usar una gran cantidad de frutas producidas y que no son consumidas como frutas frescas.

    Full Text Available Las actividades agrícolas productivas que identifican las culturas campesinas, están inscritas en una compleja diversidad simbólica, consolidada en elementos religiosos, políticos, económicos, tecnológicos y ambientales. Históricamente, el cultivo de la vid y el consumo del vino se han enriquecido de tradiciones religiosas, distinción de clases, necesidades psicológicas de beber alcohol y experimentar placer, desenlaces políticos, estrategias económicas, negocios atractivos y climas favorables. La emergente viticultura del Valle del Sol en Boyacá, no es ajena a dicha complejidad. Los campesinos que la incorporan, poseen un patrimonio social expresado en religiosidad, sensibilidad al comercio y cambios tecnológicos; Además, son capitalistas rurales, consumidores de cerveza y estrategas de la economía doméstica. Este artículo muestra indicadores para la comprensión de una producción cultural centrada en la viticultura.

    Full Text Available En este artículo analizamos las actitudes con respecto al vino de uva que mostraron tanto los conquistadores como los conquistados. El vino se vinculó a los vencedores y la chicha –fermento de maíz–, a los vencidos. Sin embargo, tanto el vino como el trigo y el aceite de oliva se convirtieron en artículos absolutamente prohibitivos para los colonos, por lo que tuvieron que transformar aceleradamente su dieta para poder sobrevivir. En breve plazo, el maíz, la yuca y las batatas se convirtieron, junto a la carne, en la base de la alimentación hispana. Lo realmente sorprendente es que aceptaran la mayor parte de la cultura gastronómica indígena, excepto la chicha –el llamado vino indígena–. Y ello por las connotaciones sociales, culturales y hasta rituales que el vino tenía, vinculado inalienablemente a la cultura europea y a la cristiandad. Abstract In this paper we analyze the attitudes towards grape wine showed both by the conquerors and the conquered. Wine was linked to winners and chichi –corn ferment–, linked to the vanquished. However, both the wine and wheat and olive oil became absolutely prohibitive items for settlers so they had to rapidly transform their diet to survive. Soon, corn, cassava and yams became, along with meat, the base of the Hispanic food. What is really surprising is that most of the Indian food culture was accepted, except chichi wine, the so- called indigenous wine. This is for the social, cultural and even ritual connotations that the wine had, inalienably linked to European culture and Christianity.

    Full Text Available El sector vitivinícola ocupa una destacada posición en el conjunto de la industria agroalimentaria española. La importancia demostrada por esta actividad se traslada también al mercado internacional donde España ostenta una posición de liderazgo tanto en términos de producción, como de ventas al exterior. Buena parte de las empresas elaboradoras de vino de nuestro país se ubican en distritos industriales, o lo que es lo mismo, en entornos geográficos caracterizados por la elevada concentración de pequeñas y medianas empresas cuya organización productiva responde a un esquema basado en la especialización flexible. En anteriores trabajos, se ha podido constatar cómo las empresas elaboradoras de vino ubicadas en este tipo de enclaves industriales presentan una mayor eficiencia respecto de competidores localizados en otro tipo de entornos. El objetivo de este artículo es profundizar en la investigación de los rasgos específicos de los distritos industriales que podrían explicar este plus de eficiencia de sus empresas. Para la identificación y cuantificación de estos factores determinantes de la eficiencia productiva se utiliza una metodología basada en modelos de ajuste paramétrico. Se lleva a cabo una aplicación empírica sobre una muestra de empresas españolas productoras de vino para los años 2000 y 2010, extraída de la base de datos SABI.

    published about the wine consumer behaviour, with applications in the context of market segmentation. Using as segmentation base nine variables that measure the importance attributed to tangible and intangible features in the process of wine acquisition, we propose a classification of the restaurateur managers in the north of Portugal into two groups.RESUMENEs notorio que para producir vinos se requiere conocimiento, pero actualmente también el conocimiento es necesario para comercializarlo. Durante siglos, los académicos y productores se empeñaron en perfeccionar técnicas que permiten hacer mejores vinos, pero el reconocimiento de que es necesario un especial esfuerzo para su comercialización es un tema reciente. Históricamente los factores de éxito de las empresas que comercializan vino se fundamentaban en la tecnología de producción y en la calidad de sus productos. Sin embargo, el aumento de la competitividad del mercado actualmente requiere el conocimiento del consumidor de vino para poder satisfacer mejor sus necesidades. El mercado del vino prosperó en refinamiento y las oportunidades de segmentación de mercado también aumentaron. Este trabajo aporta una revisión de algunos estudios sobre el comportamiento del consumidor de vino en el contexto de la segmentación de mercado. Como base de segmentación se utilizaron nueve variables que evalúan la importancia atribuida a características tangibles e intangibles en el proceso de adquisición del vino. Se propone clasificar los gestores de restauración de la región norte de Portugal en dos grupos.

    Full Text Available La presencia de residuos fitosanitarios o de ocratoxina A en vinos puede afectar a la salud de los consumidores. Pocas bodegas han implantando medidas de control, o han verificado la eficacia de las medidas adoptadas.Era interesante valorar los resultados sobre residuos fitosanitarios y ocratoxina A en muestras de vino tomadas por las bodegas o por el control oficial.Se consideraron todos los resultados analíticos sobre fitosanitarios o ocratoxina A en muestras de vino tomadas entre 2008 y 2015 disponibles en las bodegas de los distritos de salud de La Roda y Villarrobledo, o en muestras de control oficial. En total 20 analíticas de fitosanitarios y 64 determinaciones de ocratoxina A.Puesto que no hay límite legal en vino, ningún resultado sobrepasó el límite máximo de residuos fitosanitarios en uva de vinificación. La determinación de fitosanitarios en vino tiene sentido si se justifican factores de dilución o concentración durante el proceso de elaboración, respecto a los límites máximos de residuos fitosanitarios en uva, lo cual no sucedió en ningún caso. Una muestra presentó residuos de dos fitosanitarios distintos, y en una muestra de vino ecológico se obtuvo 5 mg kg-1 de iprodiona (límite máximo de residuo de iprodiona en uva: 10 mg kg-1, orientando sobre prácticas agrícolas incorrectas.Ningún resultado de ocratoxina A superó el límite legal en vino de 2 μg L-1 (Reglamento(CENº 1881/2006. Se obtuvieron concentraciones de hasta 0,44 μg L-1, demostrando que es posible la ocurrencia de ocratoxina A en vino.Es necesario que las bodegas definan y apliquen medidas de control eficaces sobre estos dos peligros.

    Full Text Available The convention theory provides a scientific framework appropriate for the analysis of the quality criteria of consumers and producers. The wine industry tends more towards differentiation by means of quality. The aim of this study is to identify the qua - lity standards currently in force within the wine market and the strategies that companies follow to achieve them. Within the framework of the convention theory we have designed a set of statistical variables that, once normalized as Z-scores, can be used as indicators of the strategies used by wine designations of origin in their search for quality. This set has been tested through a case study on Aragonese designations of origin and different models have been identified, ones focusing on specific conventions (industrial in Cariñena, domestic in Calatayud and others open to different categories of convention (Somontano and Campo de Borja.La teoría de las convenciones ofrece un marco científico adecuado para analizar los criterios de calidad de consumidores y productores. El sector del vino se orienta hacia la diferenciación por la calidad. El objetivo de la investigación es identificar los criterios de calidad vigentes en el mercado del vino y las estrategias que siguen las empresas para alcanzarlos. Dentro del marco de la teoría de las convenciones se ha diseñado un conjunto de variables estadísticas que, una vez normalizadas como números Z, sirven como indicadores de las estrategias de las denominaciones de origen vitivinícolas en su búsqueda de la calidad. Dicho conjunto se ha puesto a prueba mediante un estudio de caso sobre las denominaciones de origen aragonesas y se han identificado modelos diferentes, unos centrados en convenciones concretas (industriales en Cariñena, domésticas en Calatayud y otros abiertos a distintas categorías de convenciones (Somontano y Campo de Borja.

El análisis destacó que la edad más frecuente se halló por encima de la 5ta. década de la vida, y que hubo predominio del sexo masculino. Se practicó una reintervención durante el seguimiento; como terapéutica se utilizó el 5-fluoracilo; hubo un predominio absoluto del adenocarcinoma como variedad histológica; el diagnóstico de la entidad siempre se confirmó por Anatomía Patológica. La muestra representa el 1,2 % del total de casos de nuestra consulta y el 0,4 % de los pacientes apendicectomizados en nuestro Centro durante el período de estudio. Se recomienda insistir en el pesquisaje masivo de aquellos grupos de riesgo por parte del nivel primario de atención, para detectar precozmente la entidad y, por ende, mejorar los resultados quirúrgicos y de seguimiento posoperatorio, así como aplicar terapéutica de Sieracki en esta entidadA lengthwise and prospective study of 5 patients operated from appendix ceci cancer, who were attended in the follow-up consultation room for patients operated from colo-rectal cancer was performed. The analysis underlined that the most frequent age was over 50 years-old and males were predominant. During the follow-up period, one of the patients was operated again and treated with 5-fluoroacyl; adenocarcinoma prevailed as hystological variant and its diagnosis was always confirmed by the Pathological Anatomy Department. The sample of 5 patients represented 1.2 % of the cases attending our consultation room and 0.4 % of appendectomy-operated patients in our hospital during the studied period. The massive continuos screening of risk groups at the primary care level is recommended so as to early detect adenocarcinoma and thus improve the surgical and posoperative follow-up results and apply the

    Full Text Available El turismo del vino tiene una concepción distinta en un destino masivo de sol y playa. En este caso el enoturismo convive con ese modelo turístico y es un producto complementario que favorece la diversificación en la oferta actual. El turismo del vino puede complementar la ya existente oferta turística, con lo que las regiones, turísticas y a la vez viníferas, podrían apoyarse en las experiencias y conocimiento del vino por parte del visitante y utilizarlas como hecho diferencial competitivo frente a otros destinos de sol y playa que no poseen esta particularidad. Con ello además se favorecerá el lanzamiento del producto turístico del vino, pues la demanda latente ya esta en las zonas turísticas que rodean el área vinícola. En este sentido, una vez que se descubren las motivaciones para acudir al destino Tenerife, se localiza un mercado sensible a la ruta del vino Tacoronte-Acentejo en el asentamiento turístico del Puerto de la Cruz (una de las principales zonas turísticas de Tenerife. Así, tras conocer los beneficios buscados por el visitante del Puerto de la Cruz, se ha contrastado la existencia de dos segmentos latentes que pueden ser atraídos hacia la oferta actual de la ruta del vino en Tacoronte-Acentejo, al verificar que persiguen, además del clima y el sol y playa (principales motivaciones para viajar al destino Tenerife, otros beneficios que son susceptibles de ser ofertados por la ruta del vino.

  1. Posición anatómica y longitud del apéndice vermiforme en una población de raza mestiza de la ciudad de Bucaramanga - Colombia

    Directory of Open Access Journals (Sweden)

    Mónica Saavedra Martínez

    2009-12-01

    Full Text Available Antecedentes: La posición y longitud del apéndice vermiforme en el ser humano no son constantes y los datos sobre sus variaciones son limitados. Estudios previos soportan que algunas posiciones particulares o apéndices muy largas pueden confundir los signos clínicos de una apendicitis. Algunos autores afirman que el curso de una apendicitis puede estar influenciada por la posición del apéndice. Método: La posición y longitud del apéndice cecal fueron estudiados en 100 especímenes cadavéricos de población mestiza de Bucaramanga - Colombia. La posición del apéndice se dividió en 6 grupos: pélvica, retrocecal, preileal, postileal, subcecal y paracecal. La posición fue estudiada in situ. Resultados: La posición predominante fue la retrocecal 41%. Igualmente se encontró un porcentaje elevado de posición pélvica 28%. El promedio de la longitud del apéndice fue de 7.1 cm. Conclusión: El porcentaje de la posición retrocecal de nuestro estudio concuerda con otros estudios realizados en especímenes cadavéricos. Algunos autores han reportado porcentajes elevados de posición pélvica especialmente en poblaciones de raza negra. La posición pélvica del apéndice cecal puede producir dolor hipogástrico confundiendo los síntomas clínicos principalmente en mujeres. Los resultados de este tipo de investigaciones son importantes porque las relaciones de variables anatómicas son usadas en imágenes clínicas de apendicitis aguda; además éstas observaciones pueden alentar la mayor realización de apendicectomías por laparoscopia.

    Full Text Available En este estudio se buscó determinar y analizar el nivel y la estructura del costo y la rentabilidad del proceso de producción de la miel de abeja en los siete principales estados productores de México. Se encontró que la estructura de los costos de producción de la miel se compone mayoritariamente por el costo variable (67.1% cuyos principales rubros son la erogación para el pago de mano de obra y compra de insumos alimenticios, mientras que en el caso de los costos fijos (32.9% el principal valor lo constituyó la depreciación en infraestructura (23.3%. Esta composición del costo total tiene relevancia en la administración de la producción apícola nacional, pues las variaciones en los precios hacia la baja afectan en forma más sensible a los apicultores cuyo costo fijo medio es menor. Por su parte, la principal causa que puede provocar la variación en el nivel de la rentabilidad de las explotaciones apícolas la representa el nivel del ingreso por la venta de miel, el cual determina el precio que se le paga al productor mexicano, que depende del mercado donde realice la transacción. Finalmente, se encontró que la rentabilidad por colmena en México asciende a 158 pesos y a 305.3 pesos por cada mil pesos invertidos en activos fijos, en tanto que la relación beneficio-costo indica una rentabilidad de 38 centavos por cada peso invertido; esta actividad es rentable porque lo invertido supera la recuperación que se obtendría en pagarés de renta fija.

    Full Text Available La vitivinicultura es una de las principales industrias de la Provincia de San Juan, Argentina. Esta industria no se caracteriza por la peligrosidad de sus residuos, pero sí por sus elevados consumos de energía y agua. La energía que se utiliza en la refrigeración durante la vinificación es aproximadamente igual a un 50 a 70 por ciento del total de energía utilizada. La temperatura debe ser mantenida en un nivel óptimo durante las distintas etapas del proceso con el objetivo de garantizar las características del vino. En este artículo se presenta un modelo matemático para predecir los requerimientos energéticos durante distintas etapas de la vinificación en blanco. Se utilizó un modelo cinético para simular la fermentación y se acoplaron al mismo las ecuaciones de balance de energía. Se realizaron simulaciones de fermentación variando el volumen de los fermentadores, observándose que el requerimiento energético varía en forma lineal con el volumen de los mismos.

    Full Text Available Nuestro proyecto se inició en 1982 en la Loma de Puntalarga, entre 2500 y2600 metros de altitud, a 5,78 ºN y 72,98 ºW, en la cordillera oriental de los Andes. Las variedades más utilizadas actualmente son Pinot noir, Riesling y cruzamientos de Riesling x Silvaner. Desde 1984 se realizan trabajos de investigación sobre temas pertinentes. La baja latitud, la elevada altitud, el volumen de precipitación relativamente modesto y la transparencia del cielo, determinan el flujo de radiación solar incidente y su composición espectral, así como la amplitud del cambio de temperatura entre el día y la noche y las bajas temperaturas nocturnas, que son los rasgos del clima frío imperante en la región. El comportamiento de las cepas y las características del vino indican que las condiciones climáticas locales, pueden considerarse térmicamente equivalentesa las de ciertos territorios tradicionales renombrados. La coexistencia durante el año de todos los estadios de vegetación de la vid y la producción de vendimias con buen contenido de azúcar y niveles suficientes de acidez, hace posible la elaboración de vinos de calidad sobresaliente, de modo secuencial y continuo.En los viñedos del proyecto, las condiciones climáticas anuales son equivalentesa las otoñales, de maduración de las uvas en regiones septentrionales y australes. Al mismo tiempo, el flujo de radiación solar no sufre cambios notables y es rico en las longitudes de onda del ultravioleta B. Los dos factores pueden marcar las características de las uvas, haciendo parte así del efecto terroir.

    Full Text Available Silane Coupling Agents (SCA are widely used in fibers or particulates reinforced polymer composites to provide a water resistant bond between these reinforcements and the polymer martix. Many methods have been employed to study the interaction of SCA with inorganic surfaces in order to understand if a covalent bonding at the particulates and silane interface exists. In this work it has been used Fourier Transform infrared (FT-IR spectroscopy, differential thermal analysis (DTA-TG and specific surface área analysis in order to study the reaction of γ-aminopropiltrietoxisilane (γ-APS with slate particulates and to know the surfaces changes occurring after treatment.

La aparición del cinematógrafo supuso una revolución en lo cultural; y el mundo de la imagen vino a sumarse a otras artes milenarias, como la pintura y la literatura, las cuales habían servido al hombre para expresar ideas y sentimientos. El cine se considera una rama más de las vanguardias, y, así, el genio creativo de nuestros poetas de la Generación del 27 se vio fructificado, accediendo a territorios antes no explorados por ellos, con lo que sus imágenes y metáforas sobrepasaron los límites conocidos y se adentraron en un universo nuevo, marcado por lógicas de carácter más aperturista.

    Full Text Available After a huge production of cocoa plantings during the Sixteenth century, the town of Colima in the New Spain lost this culturing because of climate difficulties and because of the preference that the Crown made on cocoa plantings in South America. For the benefit of its settlers, the arrival of “indios chinos”, an Asian community at the town of Colima permitted the development of a small industry based on a coconut drink —“vino de cocos”—, which became the most important economic activity during the Seventeenth century. Even when it was considered a “native drink” at first —and therefore forbidden— the town council of Colima was a fundamental institution in the negotiation with viceroys and the Real Audiencia of Mexico in order to get licenses that permitted not only its elaboration but also its distribution alongside a regional market.

    Después de una intensa producción de cacao durante el siglo XVI, la villa de Colima de la Nueva España sufrió la pérdida de este cultivo por causas climáticas y por el apoyo preferente de la Corona a los sembradíos de cacao en Sudamérica. Para el beneficio de sus habitantes, la llegada de “indios chinos” o asiáticos a la villa de Colima propició el desarrollo de una pequeña industria, la del vino de cocos, que a la postre se convertiría en la principal actividad económica de la villa durante todo el siglo XVII. Aunque en un principio se consideró como una “bebida de la tierra” —y por consiguiente, prohibida—, el Cabildo colimense fue una institución clave en la negociación con los virreyes y la Real Audiencia de México para conseguir licencias que permitieran no sólo su fabricación, sino su eventual distribución en el mercado regional novohispano.

    Full Text Available El estudio de tres muestras de bodegas elaboradoras, de San Juan, Argentina, revela que la demanda energética (DE en la vinificación se vincula a los procesos térmicos que se desenvuelven en el interior de las envolventes de vinificación (EV. Estos procesos determinan la calidad del vino y se extienden desde la fermentación hasta la conservación del mismo, durante los cuales el producto requiere cierta rigurosidad térmica, a la que se refiere análogamente en este trabajo como confort del vino. Para determinar la incidencia del clima árido en las condiciones de confort del vino y en la consecuente DE en acondicionamiento térmico, se diseña una planilla de modelización semi-empírica. Mediante este instrumento se experimentan los procesos térmicos de fermentación y conservación del vino en períodos cálidos (fermentación y conservación y fríos (conservación. Los resultados de la modelización confirman que un incremento de la inercia térmica de las EV promueve la disminución de la carga térmica (QT, la cual repercute sobre la DE en la bodega.

    Two ambiguously classified Ap-stars, HR 830 and 21 CVn, are studied. The observational data are compared with the data for normal stars αDel and αLyr. Star HR 830 is classified as Ap of type Si based on the enhanced absorption in the Si lines and photometric variability in UBV. 21 CVn is classified as Ap Si based on weaker absorption of helium, the variability of helium lines, photometric periodic variability and the properties of the UV spectrum. It is concluded that the photometric periodic variability is a good indicator of Ap-properties of rapidly rotating A and late B stars. (author)

    Full Text Available La megafitodiversidad del Perú presenta especies nativas de toda índole; entre ellas frutales, los que a pesar de ser consumidos desde hace cientos de años, aún no han sido atendidos por la investigación para validar su uso, con la seguridad de que estamos consumiendo recursos que pueden superar en cantidad y calidad de vitaminas, sales minerales y pigmentos antociánicos. Así, el objetivo del presente estudio fue realizar un Inventario Taxonómico, Fitogeográfico y Etnobotánico de los frutales nativos del Norte del Perú. Se realizaron colectas a través de exploraciones botánicas programadas a varias localidades del Norte del Perú. Luego se llevó a cabo una revisión crítica de la bibliografía especializada y reforzando esta información con la obtenida por la experiencia personal tanto de los investigadores como de los pobladores locales y regionales.

    Full Text Available La innovación no solo está basada en el trabajo realizado en el viñedo, tales como diferentes localizaciones, sistemas de conducción, los tipos de riego, las protecciones contra plagas y enfermedades, sino también en el manejo que debe darse a las bodegas, por ejemplo, la maceración carbónica que se utiliza para el almacenaje de un vino blanco. Estas técnicas son aplicadas para buscar mejoras en la catación en boca y nariz. Entonces, surge la pregunta: qué es más importante para los viticultores, el mantener las prácticas tradicionales de producción o los cambios (innovación que se puedan producir en los diferentes procesos? Este artículo  explica las diferentes técnicas y métodos utilizados con el fin de permitir una innovación en la producción y distribución del vino en la región de la Rioja, tanto con las estrategias tradicionales como con la utilización de la tecnología en las bodegas, la innovación en los procesos de producción del vino el Distrito Agroindustrial Vitivinícola, la sostenibilidad de los vinos de la Rioja y los Clústeres. La Triple Hélice también es utilizada como un método para analizar las relaciones entre el gobierno, la industria de vino y la universidad. El principal resultado muestra que es más relevante el uso de la innovación en la producción y distribución del vino en la región de la Rioja, aunque para los vinicultores españoles es importante conservar sus prácticas tradicionales en el cultivo y comercialización de vinos. Finalmente, este artículo permite a los vinicultores y a la audiencia tener una idea clara sobre los diferentes beneficios obtenidos por la innovación en los varios procesos de producción de los vinos en La Rioja.

En un trabajo anterior se postuló que este amplio sistema de producción agrícola se originó hacia el final del proceso regional tardío (ca. 1300 AP en asociación con el crecimiento del principal centro habitacional de la región, La Alumbrera (Olivera et.al, 1994 y que luego fue apropiado y ampliado por el Incario. En el presente trabajo se plantean tres objetivos generales: conocer el tipo de actividades que se realizaban en el conjunto de estructuras de BC II, establecer la asociación que había entre este conjunto de estructuras y el sistema de producción agrícola e identificar posibles cambios en el uso del espacio a lo largo del tiempo. En un principio se pensó que Bajo del Coypar II formaba parte de la ampliación del espacio productivo implementada por el Imperio Incaico. Las investigaciones llevadas a cabo en el mismo permitieron determinar que efectivamente hacia las etapas más tardías y en asociación con el Incario había una estrecha relación con el sector agrícola, evidenciado en una alta frecuencia de vasijas para el almacenaje y/o el procesamiento de sustancias secas. Sin embargo, también revelaron ocupaciones más tempranas vinculadas a grupos o unidades domésticas con un desarrollo creciente de las prácticas agrícolas. De este modo, la actividad agro-pastoril fue, en este sector de la Puna meridional, mucho más temprana de lo que pensábamos.

    Full Text Available Entre 1905 y 1910 Chile y Argentina negociaron la firma de un Tratado de Comercio con vistas a suprimir los aranceles aduaneros y consagrar el principio de "Cordillera Libre". El centro de atracción eran las exportaciones de ganado argentino a Chile y de vino chileno a Argentina. Pero en ambos países se produjo una fuerte reacción de los intereses creados con vistas a frustrar las tratativas diplomáticas. Tanto la Sociedad Nacional de Agricultura (Chile como el Centro Vitivinícola Nacional (Argentina realizaron intensas gestiones para alcanzar sus objetivos; esta última corporación llegó a movilizar miles de personas para oponerse al tratado; y hasta solicitó ayuda a los ferrocarriles británicos para que obstaculizaran el ingreso de los vinos chilenos al mercado argentino. La intensa resistencia de estas corporaciones terminaron por frustrar el proyecto, el cual fue definitivamente archivado en 1911.Between 1905 and 1910, Chile and Argentina negotiated the signature of a Trade Agreement in order to abolish the customs duties and consecrate the principle of "Free Mountain Range". The centre of attraction was the exports of Argentinean cattle to Chile and of Chilean wine to Argentina. But in both countries there aroused a strong reaction of the vested interests, purposely to thwart the diplomatic negotiations. Both, the Sociedad Nacional de Agricultura (Chile as well as the Centro Vitivinícola Nacional (Argentina carried out intense negotiations to reach their objectives; the latter even movilized thousands of people to oppose the treaty and went as far as requesting the help of the British railroads to block the entrance of Chilean wines to the Argentinean market. The stiff opposition of these corporations finally frustrated the project, which was definitively filed away in 1911.

    2008-02-01

    Full Text Available RESUMEN:Este artículo ha esbozado el proceso de construcción del modelo que ha tenido como resultado un modelo de Desempeño Ocupacional. El estímulo para el desarrollo del modelo vino de la percepción de la necesidad de un modelo conceptual de la práctica de la terapia ocupacional y las ocupaciones humanas que fuera capaz de organizar el contenido de la terapia ocupacional dentro del currículo universitario en La Universidad de Sydney. El modelo actual incorpora ocho constructos fundamentales que incluyen: desempeño ocupacional, rol ocupacional, áreas ocupacionales, componentes del desempeño ocupacional, elementos centrales del desempeño ocupacional, ambiente, espacio y tiempo. Estos constructos emergieron a través de un proceso circular de teorización que incluía una revisión del material publicado, realización de pruebas sobre el terreno, reflexión y construcción del modelo. Este proceso circular continúa y la forma actual del modelo es considerada como una fase en la evolución de futuras nociones conceptuales del desempeño ocupacional.

Objetivo. Determinar las relaciones del nervio radial y sus ramas con el tubérculo de Lister, la apófisis estiloides del radio y la distribución en el dorso de la mano. Material y métodos. Se disecaron 25 piezas de cadáveres frescos. Se identificó la rama superficial del nervio radial y se midió la distancia entre la salida del nervio y la apófisis estiloides del radio. Se identificaron las ramas del nervio en el antebrazo distal y en la muñeca y se midieron respecto a la apófisis estiloides y al tubérculo de Lister. Resultados. La rama superficial del nervio radial emergió en la región dorsal y radial del tercio distal del antebrazo entre el músculo braquiradialis y el extensor carpis radialis longus, a una distancia de 8,45 cm proximal a la apófisis estiloides. Su primera rama de división discurrió palmar a la apófisis estiloides radial a una distancia promedio de 0,74 cm respecto a la misma. El tronco principal se dividió en varias ramas terminales así: proximal a la apófisis estiloides del radio (28%, a nivel de la misma (12% y distal (60%. El patrón de distribución de las ramas nerviosas en la base de los dedos más frecuente fue el del primero, segundo y el lado radial del tercer dedo (56%. Discusión. Este estudio mostró la gran variabilidad de la rama superficial del nervio radial en el dorso de la mano y la alta probabilidad de daño del mismo durante los procedimientos abiertos, artroscópicos o procedimientos percutáneos en la muñeca.

    Alba Inés Ramos Sanz

    2017-12-01

    Full Text Available En el estudio presentado en este artículo se desarrolla un modelo matemático para la simulación en tiempo real de un envolvente de vinificación representativo de la tecnología de vinificación nacional -de hormigón armado-, y se lleva a cabo un seguimiento térmico tanto del vino almacenado en este interior como en uno de acero inoxidable, con el empleo de sensores de temperatura HOBO U-12. Mediante tal simulación, se contempla el efecto producido sobre la estabilidad térmica del vino y la demanda térmica originada en la convección forzada -causada por las brisas-, bajo diversas configuraciones de bodegas. Con la herramienta validada, se realiza una sencilla optimización pasiva sobre el caso representativo. Finalmente, comparando los resultados de los casos simulados optimizados y de los casos reales, se concluye una mayor eficiencia termo-energética del caso representativo, frente a los de acero inoxidable. Asimismo, se observa que la estabilidad térmica del vino con demanda cero es factible a partir del empleo de envolventes adecuadas al clima analizado; con sencillas medidas de optimización, dicha estabilidad se acerca al prototipo de demanda cero perseguida en los modelos de referencia para la gestión de la energía.

    2009-06-01

    Although the kidney represents a major target organ in antiphospholipid syndrome (APS), renal involvement in APS was poorly recognized until recently. The most well-recognized renal manifestations of APS are the renal artery thrombosis/stenosis, renal infarction, hypertension, renal vein thrombosis, end-stage renal disease, increased allograft vascular thrombosis, some types of glomerular disease, and a small-vessel vaso-occlusive nephropathy, recently defined as APS nephropathy. APS nephropathy was first described in primary APS patients, characterized by acute thrombotic lesions in glomeruli and/or arterioles (thrombotic microangiopathy) and chronic vascular lesions such as fibrous intimal hyperplasia of arterioles and interlobular arteries, organized thrombi with or without recanalization, and fibrous arterial and arteriolar occlusions or focal cortical atrophy. APS nephropathy was also detected in further studies including patients with systemic lupus erythematosus (SLE)-related APS and SLE/non-APS patients with positive antiphospholipid antibodies, independently of lupus nephritis. The same histologic lesions, especially thrombotic mictroangiopathy, were also observed in patients with catastrophic APS. The most frequent clinical and laboratory characteristics of APS nephropathy in all the above groups of patients are hypertension (often severe), proteinuria (ranging from mild to nephrotic range), hematuria, and acute or chronic renal insufficiency.

    Full Text Available En los últimos años se produjo en la Argentina una rápida expansión de la mega-minería a cielo abierto, lo que vino acompañado de un creciente aumento de la conflictividad socio-ambiental que cuestiona en profundidad las consecuencias de la actividad extractiva. En este contexto, las múltiples críticas a la mega-minería deslegitimaron profundamente la imagen del sector y de las empresas que llevan adelante este tipo de actividad. A partir de allí, las corporaciones mega-mineras se vieron frente a la necesidad de construir una nueva estrategia comunicacional integral que les permitiera mejorar su imagen y construir consenso en torno a la actividad. El presente trabajo indaga en torno a las nuevas estrategias comunicacionales del sector mega-minero que se llevan a cabo bajo el paradigma de la Responsabilidad Social Empresaria y el “marketing experiencial”. Para ello se trabaja a partir del estudio de caso del emprendimiento mega-minero más antiguo del país, la empresa La Alumbrera (Provincia de Catamarca.

    Full Text Available The aim of this work is to design a map of apocryphal manifestations about Max Aub’s figure, writer who has constructed a universe of fake from his first works, including different genres. From the contrast with some of French texts that Aub read, and that supposed his particular cultural inheritance, it will be found a panorama that it includes so much the teachers and predecessors in the apocryphal practice maxaubiana, André Gide y Valéry Larbaud, as his more representative successors: the creative novelists of the fictitious one Sabino Ordás. On the one hand, between some and others, there will be traced the peninsular cases of major transcendency, in order to analyze the relevancy of this corpus and its function with regard to the canon. On the other hand, we are interested in valuing the will of subversion of the conventional mechanisms of the art and of the autobiography.En este trabajo se realiza una lectura del mapa de manifestaciones apócrifas alrededor de la figura de Max Aub, escritor que construye un universo de superchería literaria desde sus obras iniciales, abarcando y fusionando diferentes géneros. A partir del contraste con algunos de los textos franceses que leyó, y que supusieron una herencia cultural de gran valor, se esbozará un panorama que incluya tanto a los maestros y predecesores en la práctica apócrifa aubiana, André Gide y Valéry Larbaud fundamentalmente, como a sus sucesores más representativos: los narradores leoneses creadores de Sabino Ordás. Entre unos y otros, se rastrearán los casos peninsulares de mayor trascendencia, con el fin de llamar la atención, por una parte, sobre la relevancia de este corpus y su función con respecto al canon. Por otra parte, se analizará su voluntad de subversión de los mecanismos convencionales del arte y de la autobiografía.

    Full Text Available El propósito de este artículo es el de analizar comparativamente tres denominaciones de origen catalanas: las D. O. Montsant, Penedès y Priorat, a través de las cuales podemos observar dos tipos diferenciados de promoción turística del vino: un destino emergente y con voluntad de proyección de futuro, ligado a bodegas pequeñas y medianas que apuestan a menudo por la calidad y por producciones limitadas en un caso, y un destino reconocido en proceso de asentamiento y maduración y con una fuerte influencia de las grandes empresas y multinacionales del sector en el otro. A través de ambos casos analizaremos el estado actual de la cuestión y las problemáticas del turismo del vino en ambos destinos, cosa que nos permitirá realizar posibles recomendaciones de cara al futuro

    2014-10-01

    Recently, we developed a risk score for antiphospholipid syndrome (APS) (Global APS Score or GAPSS). This score derived from the combination of independent risk factors for thrombosis and pregnancy loss, taking into account the antiphospholipid antibodies (aPL) profile (criteria and non-criteria aPL), the conventional cardiovascular risk factors, and the autoimmune antibodies profile. We demonstrate that risk profile in APS can be successfully assessed, suggesting that GAPSS can be a potential quantitative marker of APS-related clinical manifestations. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  20. Origin and nature of the aluminium phosphate-sulfate minerals (APS associated with uranium mineralization in triassic red-beds (Iberian Range, Spain

    Directory of Open Access Journals (Sweden)

    Marfil, R.

    2013-06-01

    Full Text Available This study focuses on the mineralogical and chemical study of an Aluminium–phosphate–sulphate (APS mineralization that occurs in a clastic sequence from the Triassic (Buntsandstein of the Iberian Range. The deposit is constituted by sandstones, mudstones, and conglomerates with arenaceous matrix, which were deposited in fluvial to shallow-marine environments. In addition to APS minerals, the following diagenetic minerals are present in the clastic sequence: quartz, K-feldspar, kaolinite group minerals, illite, Fe-oxides-hidroxides, carbonate-sulphate cement-replacements and secondary uraniferous minerals. APS minerals were identified and characterized by optical microscopy, X-ray diffraction, scanning electron microscopy, and electron microprobe. Microcrystalline APS crystals occur replacing uraniferous minerals, associated with kaolinite, mica and filling pores, in distal fluvial-to-tidal arkoses-subarkoses. Given their Ca, Sr, and Ba contents, the APS minerals can be defined as a solid solution of crandallite-goyacite-gorceixite (0.53 Ca, 0.46 Sr and 0.01 Ba. The chemical composition, low LREE concentration and Sr > S suggest that the APS mineral were originated during the supergene alteration of the Buntsandstein sandstones due to the presence of the mineralizing fluids which causes the development of U-bearing sandstones in a distal alteration area precipitating from partially dissolved and altered detrital minerals. Besides, the occurrence of dickite associated with APS minerals indicates they were precipitated at diagenetic temperatures (higher than 80ºC, related to the uplifting occurred during the late Cretaceous post-rift thermal stage.Este trabajo se centra en el estudio de los minerales fosfato-sulfato alumínicos (APS que se producenen una secuencia clástica del Triásico (Buntsandstein de la Cordillera Ibérica.

    Renal involvement in antiphospholipid syndrome (APS) has been poorly recognized. A renal small-vessel vasculopathy, defined as APS nephropathy, has recently been observed in small series of patients with primary APS (PAPS) and systemic lupus erythematosus (SLE)-APS. We examined the renal histologic, clinical, and laboratory characteristics of different groups of patients with APS including catastrophic APS (CAPS). Our study included all CAPS (n=6), PAPS (n=8), and SLE-APS (n=23) patients with biopsy-proven renal involvement who were referred to our departments. The kidney biopsy specimens were retrospectively examined by the same renal pathologist. APS nephropathy was diagnosed as previously described. Demographic, clinical, and laboratory data were recorded. All patients with CAPS had acute and chronic renal vascular lesions compatible with diagnosis of APS nephropathy. Thrombotic microangiopathy (TMA), the acute lesion, was observed in all CAPS patients. Fibrous intimal hyperplasia of interlobular arteries (FIH) and focal cortical atrophy (FCA) were the most common chronic vascular lesions, occurring in 4 of 6 (66.7%) and 3 of 6 (50%) patients with CAPS, respectively. TMA was detected in 3 of 8 (37.5%) patients with PAPS and in 8 of 23 (35%) patients with SLE-APS, while FIH and FCA were found with similar frequencies in all 3 groups. Hypertension, proteinuria, hematuria, and renal insufficiency were the most common renal manifestations of all APS groups. Acute and chronic APS nephropathy lesions were detected in all 3 APS groups. Acute lesions were more prominent in CAPS, while chronic lesions were found with similar frequencies in all groups. Hypertension, proteinuria, hematuria, and renal insufficiency were the most common renal manifestations of all APS groups.

  2. Spoilage yeasts in Patagonian winemaking: molecular and physiological features of Pichia guilliermondii indigenous isolates Levaduras contaminantes en vinos patagónicos: características moleculares y fisiológicas de los aislamientos indígenas de Picchia guilliermondii

    Full Text Available Yeasts belonging to the genus Dekkera/Brettanomyces, especially the species Dekkera bruxellensis, have long been associated with the production of volatile phenols responsible for off-flavour in wines. According to recent reports, the species Pichia guilliermondii could also produce these compounds at the initial stages of fermentation. Based on the abundance of P. guilliermondii in Patagonian winemaking, we decided to study the relevance of indigenous isolates belonging to this species as wine spoilage yeast. Twenty-three indigenous isolates obtained from grape surfaces and red wine musts were analyzed in their capacity to produce volatile phenols on grape must. The relationship between molecular Random Amplified Polymorphic DNA (RAPD and physiological (killer biotype patterns detected in indigenous populations of P. guilliermondii and volatile phenol production was also evaluated. Different production levels of 4-ethylphenol, 4-vinylguaiacol and 4-ethylguaiacol were detected among the isolates; however, the values were always lower than those produced by the D. bruxellensis reference strain in the same conditions. High levels of 4-vinylphenol were detected among P. guilliermondii indigenous isolates. The combined use of RAPD and killer biotype allowed us to identify the isolates producing the highest volatile phenol levels.Las levaduras del género Dekkera/Brettanomyces, sobre todo la especie Dekkera bruxellensis, siempre han sido asociadas con la producción de fenoles volátiles responsables de aromas desagradables en los vinos. Recientemente, se ha demostrado que la especie Pichia guilliermondii también es capaz de producir estos compuestos, particularmente durante las etapas iniciales de la fermentación. Dada la abundancia de P. guilliermondii en las bodegas de la Patagonia, se decidió evaluar la importancia de algunos aislamientos indígenas de esta especie como levaduras alterantes de vinos regionales.

    In my five years as the Director of the Advanced Photon Source (APS), I have been fortunate to see major growth in the scientific impact from the APS. This year I am particularly enthusiastic about prospects for our longer-term future. Every scientific instrument must remain at the cutting edge to flourish. Our plans for the next generation of APS--an APS upgrade--got seriously in gear this year with strong encouragement from our users and sponsors. The most promising avenue that has emerged is the energy-recovery linac (ERL) (see article on page xx), for which we are beginning serious R and D. The ERL(at)APS would offer revolutionary performance, especially for x-ray imaging and ultrafast science, while not seriously disrupting the existing user base. I am very proud of our accelerator physics and engineering staff, who not only keep the current APS at the forefront, but were able to greatly impress our international Machine Advisory Committee with the quality of their work on the possible upgrade option (see page xx). As we prepare for long-term major upgrades, our plans to develop and optimize all the sectors at APS in the near future are advancing. Several new beamlines saw first light this year, including a dedicated powder diffraction beamline (11-BM), two instruments for inelastic x-ray scattering at sector 30, and the Center for Nanoscale Materials (CNM) Nanoprobe beamline at sector 26. Our partnership in the first x-ray free-electron laser (LCLS) to be built at Stanford contributes to revolutionary growth in ultrafast science (see page xx), and we are developing a pulse chirping scheme to get ps pulses at sector 7 of the APS within a year or so.

    2005-01-01

    The Westinghouse AP1000 Program is aimed at making available a nuclear power plant that is economical in the U.S deregulated electrical power industry in the near-term. The AP1000 is two-loop 1000 MWe pressurizer water reactor (PWR). It is an up rated version of the AP600. The AP1000 uses passive safety systems to provide significant and measurable improvements in plant simplification, safety, reliability, investment protection and plant costs. The AP1000 uses proven technology, which builds on over 35 years of operating PWR experience. The AP1000 received Final Design Approval by the United States Nuclear Regulatory Commission (U.S. NRC) in September 2004. The AP1000 meets the US utility requirements. The AP1000 and its sister plant the AP600 have gone through a very through and complete licensing review. This paper describes the U.S. NRC review efforts of both the AP600 and the AP1000. The detail of the review and the independent calculations, evaluations and testing is discussed. The AP600 licensing documentation was submitted in 1992. The U.S. NRC granted Final Design Approval in 1999. During the intervening 7 years, the U.S. NRC asked thousands of questions, performed independent safety analysis, audited Westinghouse calculations and analysis, and performed independent testing. The more significant areas of discussion will be described. For the AP1000 Westinghouse first engaged the U.S. NRC in pre-certification discussions to define the extent of the review required, since the design is so similar to the AP600. The AP1000 licensing documentation was submitted in March 2002. The U.S. NRC granted Final Design Approval in September 2004. During the intervening 2 1/2 years, the U.S. NRC asked hundreds of questions, performed independent safety analysis, audited Westinghouse calculations and analysis, and performed independent testing. The more significant areas of discussion will be described. The implications of this review and approval on AP1000 applications in

    It is my pleasure to introduce the 2009 annual report of the Advanced Photon Source. This was a very good year for us. We operated with high reliability and availability, despite growing problems with obsolete systems, and our users produced a record output of publications. The number of user experiments increased by 14% from 2008 to more than 3600. We congratulate the recipients of the 2009 Nobel Prize in Chemistry-Venkatraman Ramakrishnan (Cambridge Institute for Medical Research), Thomas Steitz (Yale University), and Ada Yonath (Weizmann Institute) - who did a substantial amount of this work at APS beamlines. Thanks to the efforts of our users and staff, and the ongoing counsel of the APS Scientific Advisory Committee, we made major progress in advancing our planning for the upgrade of the APS (APS-U), producing a proposal that was positively reviewed. We hope to get formal approval in 2010 to begin the upgrade. With advocacy from our users and the support of our sponsor, the Office of Basic Energy Sciences in the Department of Energy (DOE) Office of Science, our operating budgets have grown to the level needed to more adequately staff our beamlines. We were also extremely fortunate to have received $7.9 M in American Recovery and Reinvestment Act ('stimulus') funding to acquire new detectors and improve several of our beamlines. The success of the new Linac Coherent Light Source at Stanford, the world's first x-ray free-electron laser, made us particularly proud since the undulators were designed and built by the APS. Among other highlights, we note that more than one-quarter of the 46 Energy Frontier Research Centers, funded competitively across the U.S. in 2009 by the DOE, included the Advanced Photon Source in their proposed work, which shows that synchrotron radiation, and the APS in particular, are central to energy research. While APS research covers everything from fundamental to applied science (reflected by the highlights in this report

While the underlying mechanisms of these vascular lesions are not entirely known, there have been multiple theories describing the potential process of vasculopathy in APS and the various clinical manifestations associated with it. Recently, it has been demonstrated that endothelial proliferation in kidneys can be explained by the activation of the mammalian target of rapamycin complex (mTORC) pathway by antiphospholipid antibodies (aPL). These data support the existence of an APS-related vasculopathy in different locations which can explain-in part-the different manifestations of APS. This review focuses on the various manifestations of APS as a result of APS-related vasculopathy, as well as pathophysiology, current screening, and treatment options for clinicians to be aware of.

    Observations of the A5p star KIC 8677585 obtained during the Kepler 10-d commissioning run with 1-min time resolution show that it is a rapidly oscillating Ap (roAp) star with several frequencies with periods near 10 min. In addition, a low frequency at 3.142 d−1 is also clearly present....... Multiperiodic γ Doradus (γ Dor) and δ Scuti (δ Sct) pulsations, never before seen in any Ap star, are present in Kepler observations of at least three other Ap stars. Since γ Dor pulsations are seen in Ap stars, it is likely that the low frequency in KIC 8677585 is also a γ Dor pulsation. The simultaneous...... presence of both γ Dor and roAp pulsations and the unexpected detection of δ Sct and γ Dor pulsations in Ap stars present new opportunities and challenges for the interpretation of these stars. Since it is easy to confuse Am and Ap stars at classification dispersions, the nature of these Ap stars...

Su potencialidad productiva y la disponibilidad de tierras para su cultivo permiten proyectarla continuidad de su uso en plantaciones comerciales, para lo que es indispensable asegurar la provisión desemillas de adecuada calidad genética. Las semillas utilizadas en la última década se produjeron en una seriede rodales mediante ensayos para evaluar su descendencia. El objetivo del presente trabajo es evaluar estosrodales ensayando su descendencia. En este primer reporte presentamos los resultados de una evaluaciónen etapa de vivero. Se ensayaron 31 procedencias locales seleccionadas (Áreas Productoras de Semillas,APS en dos sitios, midiendo altura y diámetro a la altura del cuello en plantines de 2 años de edad. A través de análisis de la varianza se probó un claro efecto de interacción entre las APS y los sitios, y también diferencias entre las APS dentro de cada sitio. Seguidamente, se establecieron rankings de las APS por sitio y variable evaluada. A través de comparaciones de a pares se formaron grupos homogéneos. También se estimó la estabilidad genotípica de las APS por medio del cálculo de sus ecovalencias. Los resultados son aún preliminares, pero el haber probado diferencias en tan temprana edad nos alerta sobre la importancia de la procedencia de las semillas a utilizar para la producción comercial. Se espera que estas diferencias se acentúen en edades más avanzadas. Para probarlo, ya se han establecido ensayos de plantación.

Resumen del estudio: se trata de una revisión sistemática y metaanálisis, que pretende comparar los apósitos alternativos o los apósitos en la herida con dejarlas expuestas para el tratamiento posoperatorio de las heridas quirúrgicas que cicatrizan por primera intención. Comentario: El estudio se adecua a los criterios propuestos en la lista de comprobación PRISMA para revisiones sistemáticas, siendo en términos generales de buena calidad. No hubo evidencia de que algún apósito redujese significativamente las tasas de infección de la herida quirúrgica en comparación con cualquier otro o con la exposición al aire de la herida. Tampoco hubo diferencias en relación con el dolor, cicatrización o aceptación del apósito. La calidad de la evidencia es alta según la clasificación GRADE. Conclusiones: no se identificaron diferencias en las tasas de infección entre las heridas quirúrgicas cubiertas con algún apósito y las que quedaban al descubierto. Sin embargo, las decisiones sobre aplicar un apósito en la herida se deben basar tanto en los costos del apósito y en las propiedades para el control de los síntomas ofrecidas por cada tipo de apósito como en el control de los exudados.

El cultivo de la vid aparece asociado muy tempranamente a las actividades agrícolas de Chile. Hasta el siglo XVIII, los viñedos locales satisfacían holgadamente el consumo doméstico, pero sin llegar a constituir una prometedora esperanza de desarrollo agrícola. El paso desde un cultivo arbustivo escasamente expansivo a una industria agraria moderna y consolidada se dio muy recientemente. De hecho, la presencia del vino chileno en los mercados internacionales, el auge de las exportaciones, el crecimiento de la superficie vitícola y la proliferación de empresas vinícolas solo se advierte en la segunda mitad del siglo XX.

  7. AP1000 Design for Security

    International Nuclear Information System (INIS)

    2006-01-01

    Nuclear power plants are protected from potential security threats through a combination of robust structures around the primary system and other vital equipment, security systems and equipment, and defensive strategy. The overall objective for nuclear power plant security is to protect public health and safety by ensuring that attacks or sabotage do not challenge the ability to safely shutdown the plant or protect from radiological releases. In addition, plants have systems, features and operational strategies to cope with external conditions, such as loss of offsite power, which could be created as part of an attack. Westinghouse considered potential security threats during design of the AP1000 PWR. The differences in plant configuration, safety system design, and safe shutdown equipment between existing plants and AP1000 affect potential vulnerabilities. This paper provides an evaluation of AP1000 with respect to vulnerabilities to security threats. The AP1000 design differs from the design of operating PWRs in the US in the configuration and the functional requirements for safety systems. These differences are intentional departures from conventional PWR designs which simplify plant design and enhance overall safety. The differences between the AP1000 PWR and conventional PWRs can impact vulnerabilities to security threats. The NRC addressed security concerns as part of their reviews for AP1000 Design Certification, and did not identify any security issues of concern. However, much of the detailed security design information for the AP1000 was deferred to the combined Construction and Operating License (COL) phase as many of the security issues are site-specific. Therefore, NRC review of security issues related to the AP1000 is not necessarily complete. Further, since the AP1000 plant design differs from existing PWRs, it is not obvious that the analyses and assessments prepared for existing plants also apply to the AP1000. We conclude that, overall, the AP1000

    The electronic and optoelectronic properties of [A.2AP(w)/A*.2AP(WC)/C.2AP(w)/C*.2AP(WC)/C.A(w)/ C*.A(WC)]-Au8 metal-mismatch nucleobase complexes are investigated by means of density functional theory and time-dependent methods. We selected these mispairs as 2-aminopurine (2AP) produces incorporation errors when binding with cytosine (C) into the wobble (w) C.2AP(w) mispair, and is tautomerised into Watson-Crick (WC)-like base mispair C*.2AP(WC) and less effectively produces A.2AP(w)/A*.2AP(WC) mispairs. The vertical ionisation potential, vertical electron affinity, hardness and electrophilicity index of these complexes have also been discussed. The modifications of energy levels and charge density distributions of the frontier orbitals are also analysed. The absorption spectra of these complexes lie in the visible region, which suggests their application in fluorescent-bio imaging. The mechanism of cooperativity effect is studied by molecular orbital potential (MEP), atoms-in-molecules (AIM) and natural bond orbital analyses. Most metalated pairs have smaller HOMO-LUMO band gaps than the isolated mismatch nucleobases which suggest interesting consequences for electron transfer through DNA duplexes.

    This document is the final report for tank 241-AP-107 grab samples. Three grab samples were collected from riser 1 on September 11, 1997. Analyses were performed on samples 7AP-97-1, 7AP-97-2 and 7AP-97-3 in accordance with the Compatibility Grab Sampling and Analysis Plan (TSAP) (Sasaki, 1997) and the Data Quality Objectives for Tank Farms Waste Compatibility Program (DQO) (Rev. 1: Fowler, 1995; Rev. 2: Mulkey and Nuier, 1997). The analytical results are presented in the data summary report (Table 1). A notification was made to East Tank Farms Operations concerning low hydroxide in the tank and a hydroxide (caustic) demand analysis was requested. The request for sample analysis (RSA) (Attachment 2) received for AP-107 indicated that the samples were polychlorinated biphenyl (PCB) suspects. Therefore, prior to performing the requested analyses, aliquots were made to perform PCB analysis in accordance with the 222-S Laboratory administrative procedure, LAP-101-100. The results of this analysis indicated that no PCBs were present at 50 ppm and analysis proceeded as non-PCB samples. The results and raw data for the PCB analysis will be included in a revision to this document. The sample breakdown diagrams (Attachment 1) are provided as a cross-reference for relating the tank farm customer identification numbers with the 222-S Laboratory sample numbers and the portion of sample analyzed

    Active pixel sensor (APS) is a new generation of image sensors which presents several advantages relatively to charge coupled devices (CCDs) particularly for space applications (APS requires only 1 voltage to operate which reduces considerably current consumption). Irradiation was performed using {sup 60}Co gamma radiation at room temperature and at a dose rate of 150 Gy(Si)/h. 2 types of APS have been tested: photodiode-APS and photoMOS-APS. The results show that photoMOS-APS is more sensitive to radiation effects than photodiode-APS. Important parameters of image sensors like dark currents increase sharply with dose levels. Nevertheless photodiode-APS sensitivity is one hundred time lower than photoMOS-APS sensitivity.

    Although the medical literature currently provides a growing number of isolated case reports of patients with clinically well-defined antiphospholipid syndrome (APS) and persistently negative antiphospholipid antibodies (aPL), there are no studies including a series of patients addressing the clinical features of this condition. The authors assessed clinical manifestations of APS in 154 patients: 87 patients with seropositive APS and 67 patients with thrombosis and/or pregnancy morbidity persistently negative for aPL and presenting with at least two additional non-criteria manifestations of APS (the so-called 'seronegative APS', SN-APS). Patients were interviewed at the time of recruitment, and a retrospective file review was carried out. There were no significant differences in the frequency of thrombotic events or obstetric morbidity in patients with SN-APS versus patients with seropositive APS: deep vein thrombosis (31.4% vs 31.0%), pulmonary embolism (23.8% vs 28.7%), stroke (14.9% vs 17.2%), transient ischaemic attack (11.9% vs 10.3%), early spontaneous abortions (67.1% vs 52.1%), stillbirths (62.5% vs 59.4%), prematurity (28.1% vs 21.7%) or pre-eclampsia (28.1% vs 23.1%). Classic and SN-APS patients show similar clinical profiles. The results suggest that clinical management in patients with APS should not be based only on the presence of conventional aPL.

    Full Text Available Se exploró un posible efecto protector del genoma por parte de un derivado de la uva (vino Tannat. Se utilizaron poblaciones celulares haploides y diploides de Saccharomyces cerevisiae como modelo eucariota. Muestras celulares se expusieron a H2O2 en medio nutriente. El ADN se analizó por densitometría láser, luego de su aislamiento y separación por electroforesis con campos pulsados. Se aplicó la distribución de Poisson para la determinación de roturas dobles. El número de roturas dobles del ADN y la frecuencia mutagénica aumentaron en función de la dosis de H2O2, disminuyendo la probabilidad de sobrevida. La combinación de H2O2 con vino Tannat aumentó significa-tivamente la probabilidad de sobrevida y disminuyó el número de roturas dobles. No se observó efecto mutagénico por el vino Tannat. Estos efectos pudieron simularse utilizando altas concentraciones de α-tocoferol. Los resultados indican que un derivado de Vitis vinifera puede, en ciertas condiciones, disminuir las dobles roturas de ADN producidas por el H2O2 e incrementar las probabilidades de sobrevida celular. Los blancos involucrados podrían ser, entre otros, componentes intracelulares de las cascadas redox y/o enzimas de reparación del ADN.The aim of this work was to analyse a possible genome protection provided by a grape derivative (Tannat wine in yeast cell populations exposed to H2O2.

    Active pixel sensor (APS) is a new generation of image sensors which presents several advantages relatively to charge coupled devices (CCDs) particularly for space applications (APS requires only 1 voltage to operate which reduces considerably current consumption). Irradiation was performed using {sup 60}Co gamma radiation at room temperature and at a dose rate of 150 Gy(Si)/h. 2 types of APS have been tested: photodiode-APS and photoMOS-APS. The results show that photoMOS-APS is more sensitive to radiation effects than photodiode-APS. Important parameters of image sensors like dark currents increase sharply with dose levels. Nevertheless photodiode-APS sensitivity is one hundred time lower than photoMOS-APS sensitivity.

  4. Thermal Decomposition Characteristics of Orthorhombic Ammonium Perchlorate (o-AP) and an 0-AP/HTPB-Based Propellant

    1999-01-01

    A study to characterize the low-temperature reactive processes for o-AP and an AP/HTPB-based propellant (class 1.3) is being conducted in the laboratory using the techniques of simultaneous thermogravimetric modulated beam mass spectrometry (STMBMS) and scanning electron microscopy (SEM). The results presented in this paper are a follow up of the previous work that showed the overall decomposition to be complex and controlled by both physical and chemical processes. The decomposition is characterized by the occurrence of one major event that consumes up to(approx)35% of the AP, depending upon particle size, and leaves behind a porous agglomerate of AP. The major gaseous products released during this event include H(sub 2)O, O(sub 2), Cl(sub 2), N(sub 2)O and HCl. The recent efforts provide further insight into the decomposition processes for o-AP. The temporal behaviors of the gas formation rates (GFRs) for the products indicate that the major decomposition event consists of three chemical channels. The first and third channels are affected by the pressure in the reaction cell and occur at the surface or in the gas phase above the surface of the AP particles. The second channel is not affected by pressure and accounts for the solid-phase reactions characteristic of o-AP. The third channel involves the interactions of the decomposition products with the surface of the AP. SEM images of partially decomposed o-AP provide insight to how the morphology changes as the decomposition progresses. A conceptual model has been developed, based upon the STMBMS and SEM results, that provides a basic description of the processes. The thermal decomposition characteristics of the propellant are evaluated from the identities of the products and the temporal behaviors of their GFRs. First, the volatile components in the propellant evolve from the propellant as it is heated. Second, the hot AP (and HClO(sub 4)) at the AP-binder interface oxidize the binder through reactions that

    Autoimmune Addison's disease (AAD) is often associated with other components in autoimmune polyendocrine syndromes (APS). Whereas APS I is caused by mutations in the AIRE gene, the susceptibility genes for AAD and APS II are unclear. In the present study, we investigated whether polymorphisms or copy number variations in the AIRE gene were associated with AAD and APS II. First, nine SNPs in the AIRE gene were analyzed in 311 patients with AAD and APS II and 521 healthy controls, identifying no associated risk. Second, in a subgroup of 25 of these patients, AIRE sequencing revealed three novel polymorphisms. Finally, the AIRE copy number was determined by duplex quantitative PCR in 14 patients with APS I, 161 patients with AAD and APS II and in 39 healthy subjects. In two Scandinavian APS I patients previously reported to be homozygous for common AIRE mutations, we identified large deletions of the AIRE gene covering at least exon 2 to exon 8. We conclude that polymorphisms in the AIRE gene are not associated with AAD and APS II. We further suggest that DNA analysis of the parents of patients found to be homozygous for mutations in AIRE, always should be performed.

    The international consensus for the classification of antiphospholipid syndrome (APS) requires clinical and laboratory criteria to be considered at an equal level for diagnosing APS. Thus, detection of antiphospholipid antibodies (aPL) being a hallmark of APS has been the object of intensive investigation over the past 40 years. However, appropriate detection of aPL still remains a laboratory challenge due to their heterogeneity comprising autoantibodies reactive to different phospholipid-binding plasma proteins, such as beta-2 glycoprotein I (β2GPI) and prothrombin. The relevance of aPL interacting with phospholipids other than cardiolipin (CL, diphosphatidylglycerol), such as phosphatidylserine (PS), remains elusive with regard to the diagnosis of APS. Recently, the concept of aPL profiling has been introduced to assess the risk of thrombotic complications in patients with APS. New assay techniques, apart from enzyme-linked immunosorbent assays (ELISAs) recommended by the international consensus for the classification of APS, have been proposed for multiplexing of aPL testing. Line immunoassays (LIAs) employing a novel hydrophobic solid phase for the simultaneous detection of different aPL seem to be an intriguing alternative. We evaluated a novel multiplex LIA employing a hydrophobic membrane coated with different phospholipid (PL)-binding proteins or PLs. The performance characteristics of this new multiplexing assay technique demonstrated its usefulness for aPL profiling. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    This study is intended to clarify in detail the tautomeric transformations of the wobble (w) G*·2AP(w) and A·2AP(w) nucleobase mispairs involving 2-aminopurine (2AP) into the Watson-Crick (WC) G·2AP(WC) and A*·2AP(WC) base mispairs (asterisks denote mutagenic tautomers of the DNA bases), respectively, by quantum-mechanical methods and Bader's Quantum Theory of Atoms in Molecules. Our previously reported methodology has been used, which allows the evolution of the physico-chemical parameters to be tracked along the entire internal reaction coordinate (IRC), not exclusively in the stationary states of these reactions. These biologically important G*·2AP(w) ↔ G·2AP(WC) and A·2AP(w) ↔ A*·2AP(WC) w ↔ WC tautomerisations, which are involved in mutagenic tautomerically-conformational pathways, determine the origin of the transitions and transversions induced by 2AP. In addition, it is established that they proceed through planar, highly stable, zwitterionic transition states and they exhibit similar physico-chemical profiles and stages of sequential intrapair proton transfer, followed by spatial rearrangement of the nucleobases relative to each other within the base pairs. These w ↔ WC tautomerisations occur non-dissociatively and are accompanied by a significant alteration in geometry (from wobble to Watson-Crick and vice versa) and redistribution of the specific intermolecular interactions, which can be divided into 10 patterns including AHB H-bonds and loosened A-H-B covalent bridges along the IRC of tautomerisation. Based on the redistribution of the geometrical and electron-topological parameters of the intrapair hydrogen bonds, exactly 9 key points have been allocated to characterize the evolution of these reactions.

    Full Text Available El complejo suspensorio del hombro es una estructura sumamente importante, compuesta por un anillo de huesos y tejidos blandos. Las lesiones aisladas de este complejo anatómico son frecuentes y no afectan su estabilidad. La interrupción doble conduce a la inestabilidad de esta estructura y usualmente requiere tratamiento quirúrgico. La triple interrupción, por su parte, es sumamente rara y es encontrada en casos de trauma de alta energía a menudo en asociación con otras lesiones. Se presenta una triple lesión del complejo suspensorio del hombro en un paciente de 46 años de edad, con una fractura de la glenoides, del acromion tipo III de Kuhn y de la coracoides tipo II de Ogawa. En este caso, la fractura del acromion fue tratada con fijación percutánea con alambres de Kirschner, por tener asociado lesiones de partes blandas que contraindicaron la reducción abierta. La fractura de la glenoides y de la apófisis coracoides fueron tratadas conservadoramente. Después de 6 meses de evolución, el paciente tuvo un resultado funcional aceptable, con una abducción de 90 grados, los 30 grados de rotación externa y 70 de rotación interna, además asintomático y consolidación de todas las fracturas. A pesar de ser catalogada de una lesión grave del cinturón escapular y estar asociada a otras lesiones se obtuvo un resultado satisfactorio al final del tratamiento.

    Solid rocket propellants based on dual mixes of inorganic crystalline oxidizers (ammonium nitrate (AN) and ammonium perchlorate (AP)) with binder and a mixture of micrometric-nanometric aluminum were investigated. Ammonium nitrate is a low-cost oxidizer, producing environment friendly combustion products but with lower specific impulse compared to AP. The better performance obtained with AP and the low quantity of toxic emissions obtained by using AN have suggested an interesting compromise based on a dual mixture of the two oxidizers. To improve the thermal response of raw AN, different types of phase stabilized AN (PSAN) and AN/AP co-crystals were investigated.

    The distinguishing features of Westinghouse's AP1000 advanced passive pressurized water reactor are highlighted. In particular, the AP1000's passive safety features are described as well as their implications for simplifying the design, construction, and operation of this design compared to currently operating plants, and significantly increasing safety margins over current plants as well. The AP1000 design specifically incorporates the knowledge acquired from the substantial accumulation of power reactor operating experience and benefits from the application of the Probabilistic Risk Assessment in the design process itself. The AP1000 design has been certified by the US Nuclear Regulatory Commission under its new rules for licensing new nuclear plants, 10 CFR Part 52, and is the subject of six combined Construction and Operating License applications now being developed. Currently the AP1000 design is being assessed against the EUR Rev C requirements for new nuclear power plants in Europe. (author)

    Adaptor protein complex-4 (AP-4) is a heterotetrameric protein complex which plays a key role in vesicle trafficking in neurons. Mutations in genes affecting different subunits of AP-4, including AP4B1, AP4E1, AP4S1, and AP4M1, have been recently associated with an autosomal recessive phenotype, consisting of spastic tetraplegia, and intellectual disability (ID). The overlapping clinical picture among individuals carrying mutations in any of these genes has prompted the terms "AP-4 deficiency syndrome" for this clinically recognizable phenotype. Using whole-exome sequencing, we identified a novel homozygous mutation (c.991C>T, p.Q331*, NM_006594.4) in AP4B1 in two siblings from a consanguineous Pakistani couple, who presented with severe ID, progressive spastic tetraplegia, epilepsy, and microcephaly. Sanger sequencing confirmed the mutation was homozygous in the siblings and heterozygous in the parents. Similar to previously reported individuals with AP4B1 mutations, brain MRI revealed ventriculomegaly and white matter loss. Interestingly, in addition to the typical facial gestalt reported in other AP-4 deficiency cases, the older brother presented with congenital left Horner syndrome, bilateral optic nerve atrophy and cataract, which have not been previously reported in this condition. In summary, we report a novel AP4B1 homozygous mutation in two siblings and review the phenotype of AP-4 deficiency, speculating on a possible role of AP-4 complex in eye development. © 2018 Wiley Periodicals, Inc.

    Two biological control agents, Bacillus subtilis AP-01 (Larminar(™)) and Trichoderma harzianum AP-001 (Trisan(™)) alone or/in combination were investigated in controlling three tobacco diseases, including bacterial wilt (Ralstonia solanacearum), damping-off (Pythium aphanidermatum), and frogeye leaf spot (Cercospora nicotiana). Tests were performed in greenhouse by soil sterilization prior to inoculation of the pathogens. Bacterial-wilt and damping off pathogens were drenched first and followed with the biological control agents and for comparison purposes, two chemical fungicides. But for frogeye leaf spot, which is an airborne fungus, a spraying procedure for every treatment including a chemical fungicide was applied instead of drenching. Results showed that neither B. subtilis AP-01 nor T harzianum AP-001 alone could control the bacterial wilt, but when combined, their controlling capabilities were as effective as a chemical treatment. These results were also similar for damping-off disease when used in combination. In addition, the combined B. subtilis AP-01 and T. harzianum AP-001 resulted in a good frogeye leaf spot control, which was not significantly different from the chemical treatment.

Para ello se calcularon las dosis diarias definidas cada día de determinado fármaco de los grupos clasificados según ATC como tetraciclinas, anfenicoles, penicilinas de amplio espectro, cefalosporinas, sulfonamidas y trimetoprim, macrólidos, estreptomicinas y quinolonas. Además, se tomaron las cifras de pacientes inscriptos a penicilina benzatínica y se comparó con la población expuesta obtenida a partir de las DHD. Las penicilinas son las de mayor consumo con tendencia al aumento, igual que los aminoglucósidos, mientras que la tetraciclina presenta cifras mayores de DHD. La tendencia del cloranfenicol es a disminuir. La población expuesta está muy por debajo de los pacientes inscriptos en penicilina benzatínica y las líneas de tendencia no son similares. Excepto la docixiclina, el resto de los antimicrobianos recomendados en la Guía Terapéutica para APS se encuentran en el Listado Básico de Medicamentos del país para el nivel primario de atención médica.With the objective of describing the pattern of drug use in antimicrobial-based treatment in the primary health care in Cuba from 1989 to 2000, we designed a retrospective descriptive and observational study, classified into the study of drug use as consumption.

    The AP1000 is a design of a nuclear reactor of pressurized water (PWR) of 1000 M We with characteristic of safety in a passive way; besides presenting simplifications in the systems of the plant, the construction, the maintenance and the safety, the AP1000 is a design that uses technology endorsed by those but of 30 years of operational experience of the PWR reactors. The program AP1000 of Westinghouse is focused to the implementation of the plant to provide improvements in the economy of the same one and it is a design that is derived directly of the AP600 designs. On September 13, 2004 the US-NRC (for their initials in United States- Nuclear Regulatory Commission) approved the final design of the AP1000, now Westinghouse and the US-NRC are working on the whole in a complete program for the certification.

  14. Genome-Wide Identification of the Target Genes of AP2-O, a Plasmodium AP2-Family Transcription Factor.

    2015-05-01

    Full Text Available Stage-specific transcription is a fundamental biological process in the life cycle of the Plasmodium parasite. Proteins containing the AP2 DNA-binding domain are responsible for stage-specific transcriptional regulation and belong to the only known family of transcription factors in Plasmodium parasites. Comprehensive identification of their target genes will advance our understanding of the molecular basis of stage-specific transcriptional regulation and stage-specific parasite development. AP2-O is an AP2 family transcription factor that is expressed in the mosquito midgut-invading stage, called the ookinete, and is essential for normal morphogenesis of this stage. In this study, we identified the genome-wide target genes of AP2-O by chromatin immunoprecipitation-sequencing and elucidate how this AP2 family transcription factor contributes to the formation of this motile stage. The analysis revealed that AP2-O binds specifically to the upstream genomic regions of more than 500 genes, suggesting that approximately 10% of the parasite genome is directly regulated by AP2-O. These genes are involved in distinct biological processes such as morphogenesis, locomotion, midgut penetration, protection against mosquito immunity and preparation for subsequent oocyst development. This direct and global regulation by AP2-O provides a model for gene regulation in Plasmodium parasites and may explain how these parasites manage to control their complex life cycle using a small number of sequence-specific AP2 transcription factors.

  15. Advanced APS Impacts on Vehicle Payloads

    Science.gov (United States)

    Schneider, Steven J.; Reed, Brian D.

    1989-01-01

    Advanced auxiliary propulsion system (APS) technology has the potential to both, increase the payload capability of earth-to-orbit (ETO) vehicles by reducing APS propellant mass, and simplify ground operations and logistics by reducing the number of fluids on the vehicle and eliminating toxic, corrosive propellants. The impact of integrated cryogenic APS on vehicle payloads is addressed. In this system, launch propulsion system residuals are scavenged from integral launch propulsion tanks for use in the APS. Sufficient propellant is preloaded into the APS to return to earth with margin and noncomplete scavenging assumed. No propellant conditioning is required by the APS, but ambient heat soak is accommodated. High temperature rocket materials enable the use of the unconditioned hydrogen/oxygen in the APS and are estimated to give APS rockets specific impulse of up to about 444 sec. The payload benefits are quantified and compared with an uprated monomethyl hydrazine/nitrogen tetroxide system in a conservative fashion, by assuming a 25.5 percent weight growth for the hydrogen/oxygen system and a 0 percent weight growth for the uprated system. The combination and scavenging and high performance gives payload impacts which are highly mission specific. A payload benefit of 861 kg (1898 lbm) was estimated for a Space Station Freedom rendezvous mission and 2099 kg (4626 lbm) for a sortie mission, with payload impacts varying with the amount of launch propulsion residual propellants. Missions without liquid propellant scavenging were estimated to have payload penalties, however, operational benefits were still possible.

  16. AP1000 design and construction integration

    Winters, James W.; Clelland, Jill A.

    2004-01-01

    Construction costs of commercial nuclear generating plants must be reduced in order to expand the future use of nuclear energy. Two of the drivers of plant construction costs are the cost of financing during the construction duration and the substantial amount of skilled craft labor hours needed on site during construction. The application of information technology (IT) has been used to understand and reduce both of these drivers by establishing parallel construction paths using modules and integrating construction sequence review into the design process. In a program sponsored by EPRI, Westinghouse has modeled the construction of AP1000 in '4D' to show its viability, to improve its logic, to improve the plant design for constructibility and overall to reduce time and risk in the construction schedule. The design of most of AP1000 was constrained to be a duplicate of AP600 except where components required expansion for the higher power level. As a result, the construction schedule for AP1000 is as mature and as robust as that for AP600. Two areas important to the construction of AP1000 did require some design work because they could not remain the same as AP1000. First, the turbine building had to be redesigned to accommodate the larger turbine and its support systems. Again, as much of the AP600 design and philosophy as possible was retained. The building required enlargement and the basemat, foundations, steel structure and structural modules required modification. As concrete, steel, and equipment were defined by the designers, they were matched to the original AP600 turbine building schedule. This forced designers to assemble files to be consistent with building assembly activities and to think about constructibility as they defined the final design. Second, the reinforcement structure within the concrete under and supporting the containment vessel required detail design. Westinghouse was fortunate to have the constructor Obayashi of Japan recommend a detailed

    The AP1000{sup TM} plant is an 1100 M We pressurized water reactor (PWR) with passive safety features and extensive plant simplifications that enhance construction, operation, maintenance and safety. Modules are used extensively in the design of the AP1000 plant nuclear island. The AP1000 plant uses modern, modular-construction techniques for plant construction. The design incorporates vendor-designed skids and equipment packages, as well as large, multi-ton structural modules and special equipment modules. Modularization allows traditionally sequential construction tasks to be completed simultaneously. Factory-built modules can be installed at the site in a planned construction schedule. The modularized AP1000 plant allows many more construction activities to proceed in parallel. This reduces plant construction calendar time, thus lowering the costs of plant financing. Furthermore, performing less work onsite significantly reduces the amount of skilled field-craft labor, which costs more than shop labor. In addition to labor cost savings, doing more welding and fabrication in a factory environment raises the quality of work, allowing more scheduling flexibility and reducing the amount of specialized tools required onsite. The site layout for the AP1000 plant has been established to support modular construction and efficient operations during construction. The plant layout is compact, using less space than previous conventional plant layouts. This paper provides and overview of the AP1000 plant modules with an emphasis on structural modules. Currently the Westinghouse AP1000 plant has four units under construction in China and four units under construction in the United States. All have shown successful fabrication and installation of various AP1000 plant modules. (Author)

We present the latest programs spearheaded by the Committee on the Status of Women in Physics (CSWP), with highlights from other diversity and education efforts. The CSWP is working to increase the fraction of women in physics, understand and implement solutions for gender-specific issues, enhance professional development opportunities for women in physics, and remedy issues that impact gender inequality in physics. The Conferences for Undergraduate Women in Physics, Professional Skills Development Workshops, and our new Professional Skills program for students and postdocs are all working towards meeting these goals. The CSWP also has site visit and conversation visit programs, where department chairs request that the APS assess the climate for women in their departments or facilitate climate discussions. APS also has two significant programs to increase participation by underrepresented minorities (URM). The newest program, the APS National Mentoring Community, is working to provide mentoring to URM undergraduates, and the APS Bridge Program is an established effort that is dramatically increasing the number of URM PhDs in physics.

    2012-01-01

    Antiphospholipid syndrome (APS) is a rare clinical disorder characterized by thromboembolic manifestations and/or obstetric complications. Along with the clinical symptoms and signs, serum antiphospholipid antibodies have to be detected. APS can be primary, i.e., without any concomitant disorders, or secondary to other autoimmune diseases, particularly systemic lupus erythematosus. Criteria for the diagnosis of APS have been clearly established. Hyperacute APS (or catastrophic antiphospholipid syndrome), often with a poor prognosis, must meet four criteria: involvement of three or more organs, rapid evolution of clinical manifestations, microangiopathic occlusion of small blood vessels at biopsy, and presence of antiphospholipid antibodies. The rationale for apheresis treatment is the removal of pathogenetic antibodies involved in the development of tissue damage. Our experience includes 23 patients, in particular 15 women treated for 19 pregnancies. According to the National Guidelines Program, the effectiveness of apheresis in catastrophic syndrome has a level of evidence of V/VI, with a strength of recommendation A; in highrisk pregnancy it has a level of evidence of V with a strength of recommendation B. It will be necessary to better define the prognosis of various categories of pregnant patients with APS, as well as useful laboratory parameters to monitor its clinical course and anticipate any complications of pregnancy.

In the strategic planning the aim is to foster the growth of existing user communities and foresee new areas of research. This coming year finds the APS engaged in putting together, along with the users, a blueprint for the next five years, and making the case for a set of prioritized investments in beamlines, the accelerator, and infrastructure, each of which will be transformational in terms of scientific impact. As this is written plans are being formulated for an important user workshop on October 20-21, 2008, to prioritize strategic plans. The fruit from past investments can be seen in this report. Examples include the creation of a dedicated beamline for x-ray photon correlation spectroscopy at Sector 8, the evolution of dedicated high-energy x-ray scattering beamlines at sectors 1 and 11, a dedicated imaging beamline at Sector 32, and new beamlines for inelastic scattering and powder diffraction. A single-pulse facility has been built in collaboration with Sector 14 (BioCARS) and Phil Anfinrud at the National Institutes of Health, which will offer exceptionally high flux for single-pulse diffraction. The nanoprobe at Sector 26, built and operated jointly by the Argonne Center for Nanoscale Materials and the X-ray Operations and Research (XOR) section of the APS X-ray Science Division, has come on line to define the state of the art in nanoscience.

    To evaluate the prevalence of traditional risk factors in patients with primary antiphospholipid syndrome (APS) in comparison to those with systemic lupus erythematosus-secondary APS. Transversal study of 96 APS patients (Sapporo's criteria). Demographic and clinical data, cardiovascular risk factors and drug use were investigated. Thirty-nine Primary APS and 57 secondary APS were included. The groups did not differ regarding age (38.5 +/- 9.9 vs. 39.4 +/- 10.5 years, p=0.84) and female gender (84.6 vs. 96.5%, p=0.06), respectively. Arterial events were more observed in primary than secondary APS (59 vs. 36.8%, p=0.04) patients. No difference was seen concerning venous and obstetric events. In regard to traditional risk factors for cardiovascular disease, both groups were comparable related to current or previous smoking, sedentarism, family history for coronary disease, systemic hypertension, diabetes mellitus, overweight and obesity. The frequencies of altered lipid profiles were alike in the two groups, except for a higher prevalence of low HDL-c levels in primary APS group (84.6 vs. 45.5%, p=0.0001). Concerning drug use, no significant differences were observed related to chloroquine and statin use, however the secondary APS patients had a higher rate of prednisone use (10.2 vs. 57.9%, pAPS, except for a high frequency of low HDL-c in primary APS patients.

    2013-01-01

    Type 2 autoimmune polyendocrine syndromes (APS-2) are the most frequent disorders associating several organ-specific autoimmune diseases. Their high prevalence is due to the fact that the main manifestations of APS-2, such as thyroidal autoimmunity, type 1 diabetes, autoimmune gastric atrophy and vitiligo, are common diseases. APS-2 represents a clinical model that can serve to help unravel the mechanisms underlying autoimmunity. Diagnosis of APS-2 is a challenge for the clinician, especially in poorly symptomatic forms, and may require systematic screening based on measurement of autoantibodies and functional markers.

  14. AP1000 Containment Design and Safety Assessment

    2002-01-01

    The AP1000 is an up-rated version of the AP600 passive plant design that recently received final design certification from the US NRC. Like AP600, the AP1000 is a two-loop, pressurized water reactor featuring passive core cooling and passive containment safety systems. One key safety feature of the AP1000 is the passive containment cooling system which maintains containment integrity in the event of a design basis accident. This system utilizes a high strength, steel containment vessel inside a concrete shield building. In the event of a pipe break inside containment, a high pressure signal actuates valves which allow water to drain from a storage tank atop the shield building. Water is applied to the top of the containment shell, and evaporates, thereby removing heat. An air flow path is formed between the shield building and the containment to aid in the evaporation and is exhausted through a chimney at the top of the shield building. Extensive testing and analysis of this system was performed as part of the AP600 design certification process. The AP1000 containment has been designed to provide increased safety margin despite the increased reactor power. The containment volume was increased to accommodate the larger steam generators, and to provide increased margin for containment pressure response to design basis events. The containment design pressure was increased from AP600 by increasing the shell thickness and by utilizing high strength steel. The passive containment cooling system water capacity has been increased and the water application rate has been scaled to the higher decay heat level. The net result is higher margins to the containment design pressure limit than were calculated for AP600 for all design basis events. (authors)

    Renal involvement in antiphospholipid syndrome (APS), either primary or systemic lupus erythematosus (SLE)-related APS, includes renal artery stenosis or thrombosis, renal infarction, renal vein thrombosis and a small-vessel vaso-occlusive nephropathy defined as "antiphospholipid antibody (aPL)-associated nephropathy." aPL-associated nephropathy is characterized by acute lesions, thrombotic microangiopathy, and chronic lesions such as fibrous intimal hyperplasia, organizing thrombi with or without recanalization, fibrous occlusions of arteries or arterioles and focal cortical atrophy. Systemic hypertension, hematuria, proteinuria (ranging from mild to nephrotic level) and renal insufficiency represent the major clinical manifestations associated with aPL-associated nephropathy. Similar renal histologic and clinical characteristics have been described among all different groups of patients with positive aPL (primary APS, SLE-related APS, catastrophic APS and SLE/non-APS with positive aPL). In patients with aPL-associated nephropathy lesions in the absence of other causes associated with similar histological characteristics, aPL testing needs to be considered. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  17. Raising the acceptance of the AP2-line

    1989-01-01

    The 120 GeV Main Ring proton beam collides with the target at the end of the AP-1 line and creates antiprotons and other secondary particles. The AP-2 line transfers the negative particles from the target to the Debuncher. To provide a bigger antiproton stack size in the Accumulator, both the Debuncher as well as the AP-2 line acceptance have to be raised. This is a proposal for the improvement of the AP-2 line acceptance. The first part of the memo presents an acceptance examination of the existing AP-2 line by computer simulation, while the second presents a short proposal for aperture corrections. The computer program TURTLE was used to trace antiprotons through the AP-2 line without taking into account other negative charged particles. Betatron functions were obtained from the output of the SYNCH computer program. The SYNCH program was also used to check the dispersion match between the AP-2 line and the Debuncher. 3 refs., 6 figs., 5 tabs

    As the western hemisphere's premier x-ray synchrotron radiation source, the Advanced Photon Source (APS) continues to advance the state of the art in insertion device technology in order to maintain record high brightness, especially in the hard x-ray wavelength region. Due to the unique bunch pattern used for normal APS operations and its ultimate capabilities, the APS has chosen superconducting technology for its future hard x-ray undulator sources. In the last several years, the APS in collaboration with the Budker Institute of Nuclear Physics has being developing the technology for planar, small-period superconducting undulators (SCUs). These developments include the design and construction of several prototypes and the construction of the necessary mechanical, vacuum, and cryogenic infrastructure at the APS site. Several prototypes of the SCU magnetic structure have been built and tested. The first SCU is assembled and will be installed in the APS storage ring at the end of 2012. Expected SCU performance in terms of x-ray brightness should noticeably exceed that of existing APS undulators. Immediately after commissioning, the SCU will be used at APS Sector 6 as the radiation source for high-energy x-ray studies.

    2009-10-01

    Scintillation properties of LuAP:Ce and LuAP:Ce,Sc crystal series were studied under excitation by gamma-rays from a 137Cs source. Both series demonstrated comparable optical quality in terms of underlying absorption at 260 nm, slope of the optical edge and transmission in the range of emission. The light yield of LuAP:Ce crystals measured in 0.2 cm times 0.2 cm times 0.8 cm pixels increases linearly with the Ce concentration reaching at 0.58 at. % 6448 plusmn 322 ph/MeV and 9911 plusmn 496 ph/MeV in the long and in the short directions respectively (the light yield ratio is 65%) and shows no sign of light saturation. The energy resolution is found to depend, among other factors, on the uniformity of Ce concentration within the pixels and is improved to 7.1 plusmn 0.4% (I = 0.2 cm), 9.5 plusmn 0.5% (I = 0.8 cm). Intentional co-doping with Sc + ions was tested and resulted in increase of the Ce distribution coefficient to about 0.3. This enabled to increase the concentration of Ce in LuAP:Ce,Sc crystals up to 0.7 at. %, while conserving high optical quality. In contrast to LuAP:Ce, the light yield in LuAP:Ce,Sc crystals does not increase with Ce concentration, the photo peak being gradually suppressed. The involved mechanisms are discussed basing on measurements of the unit cell volumes, Ce concentration uniformity, x-ray rocking spectra, absorption spectra of pure and variously doped LuAP crystals, and emission spectra under different excitations.

    Under the Additional Protocol, States should provide the IAEA with expanded declarations of activities related to the nuclear fuel cycle and other nuclear activities, and with expanded access to the relevant information and sites to allow the IAEA to verify the completeness of these declarations. The AP to the Safeguards Agreement (the Additional Protocol) was signed on June 21{sup st}, 1999 and entered into force on February 19{sup th}, 2004. ROK submitted initial declarations in August 2004. Since then, ROK has been submitting annual updated reports of initial declaration on every May 15{sup th}. To achieve successful implementation, it is necessary to collect the information for each individual article in Article 2 of the AP and verify the declared information provided by facility operators. Therefore, the cooperation among the ministries and offices concerned is a prerequisite for successful implementation of AP. Unfortunately, the formal procedure for inter-organizational information sharing and cooperation is not established. This paper will briefly outline the AP declarations and suggest the information sharing among the ministries, offices and organizations for effective and efficient implementation of AP. The State authority has responsibility for AP implementation and it should verify correctness and completeness of the information declared by facility operators before submitting the declarations. The close cooperation and information sharing among the ministries, offices and organizations are indispensable to effective and efficient implementation of AP.

    In recent years, antiphospholipid syndrome (APS) has been increasingly recognised in various paediatric autoimmune and nonautoimmune diseases, but the relatively low prevalence and heterogeneity of APS in childhood made it very difficult to study in a systematic way. The project of an international registry of paediatric patients with APS (the Ped-APS Registry) was initiated in 2004 to foster and conduct multicentre, controlled studies with large number of paediatric APS patients. The Ped-APS Registry is organised as a collaborative project of the European Forum on Antiphospholipid Antibodies and Juvenile Systemic Lupus Erythematosus Working Group of the Paediatric Rheumatology European Society. Currently, it documents a standardised clinical, laboratory and therapeutic data of 133 children with antiphospholipid antibodies (aPL)-related thrombosis from 14 countries. The priority projects for future research of the Ped-APS Registry include prospective enrollment of new patients with aPL-related thrombosis, assessment of differences between the paediatric and adult APS, evaluation of proinflammatory genotype as a risk factor for APS manifestations in childhood and evaluation of patients with isolated nonthrombotic aPL-related manifestations.

    The analysis is based on the simulation of a Small Break Loss-of-Coolant-Accident in the AP1000 nuclear reactor using a Gothic 8.0 tri dimensional model created in the Science and Technology Group of Nuclear Fision Advanced Systems of the UPM. The SBLOCA has been simulated with TRACE 5.0 code. The main purpose of this work is the study of the thermo-hydraulic behaviour of the AP1000 containment during a SBLOCA. The transients simulated reveal close results to the realistic behaviour in case of an accident with similar characteristics. The pressure and temperature evolution enables the identification of the accident phases from the RCS point of view. Compared to the licensing calculations included in the AP1000 Safety Analysis, it has been proved that the average pressure and temperature evolution is similar, yet lower than the licensing calculations. However, the temperature and inventory distribution are significantly heterogeneous. (Author)

  11. Effect of oxygen and nitroaromatic cell radiosensitizers on radiation-induced cleavage of internucleotide bonds: ApA, dApA, and poly(A)

    International Nuclear Information System (INIS)

    1975-01-01

    Irradiation of the dinucleoside monophosphates ApA and dApA in deoxygenated solution leads to a preferential cleavage of the 3' end of the internucleotide bond. Cleavage at the 3' bond is favored to the extent of 2 to 1 over 5' cleavage. Oxygen and nitroaromatic compounds inhibit 3' bond breaking in ApA and dApA in agreement with earlier findings from studies of 3'- and 5'-mononucleotides. In contrast to the mononucleotide results, no enhancement of 5' cleavage is observed for ApA and dApA irradiated in the presence of oxygen or the nitroaromatic additives. The over-all effect of the additives is to decrease the combined (3' and 5') yield of internucleotide bond breaking in ApA and dApA. This phenomenon is also observed for polyadenylic acid in the presence of the nitroaromatics. Oxygen marginally enhances internucleotide bond breaking in polyadenylic acid (factor 1.1) over that seen in deoxygenated solution. Postirradiation alkaline hydrolysis of dApA leads to further ester cleavage revealing the presence of radiation-induced alkali-labile bonds. The number of these bonds decreases in the order oxygen greater than nitrofurans greater than nitrobenzenes approximately irradiation in the absence of additives

  12. APS beamline standard components handbook

    1992-01-01

    It is clear that most Advanced Photon Source (APS) Collaborative Access Team (CAT) members would like to concentrate on designing specialized equipment related to their scientific programs rather than on routine or standard beamline components. Thus, an effort is in progress at the APS to identify standard and modular components of APS beamlines. Identifying standard components is a nontrivial task because these components should support diverse beamline objectives. To assist with this effort, the APS has obtained advice and help from a Beamline Standardization and Modularization Committee consisting of experts in beamline design, construction, and operation. The staff of the Experimental Facilities Division identified various components thought to be standard items for beamlines, regardless of the specific scientific objective of a particular beamline. A generic beamline layout formed the basis for this identification. This layout is based on a double-crystal monochromator as the first optical element, with the possibility of other elements to follow. Pre-engineering designs were then made of the identified standard components. The Beamline Standardization and Modularization Committee has reviewed these designs and provided very useful input regarding the specifications of these components. We realize that there will be other configurations that may require special or modified components. This Handbook in its current version (1.1) contains descriptions, specifications, and pre-engineering design drawings of these standard components. In the future, the APS plans to add engineering drawings of identified standard beamline components. Use of standard components should result in major cost reductions for CATs in the areas of beamline design and construction

  14. Roles of AP-2 in clathrin-mediated endocytosis.

    Directory of Open Access Journals (Sweden)

    Emmanuel Boucrot

    2010-05-01

    Full Text Available The notion that AP-2 clathrin adaptor is an essential component of an endocytic clathrin coat appears to conflict with recent observations that substantial AP-2 depletion, using RNA interference with synthesis of AP-2 subunits, fails to block uptake of certain ligands known to internalize through a clathrin-based pathway.We report here the use of in vivo imaging data obtained by spinning-disk confocal microscopy to study the formation of clathrin-coated structures at the plasma membranes of BSC1 and HeLa cells depleted by RNAi of the clathrin adaptor, AP-2. Very few clathrin coats continue to assemble after AP-2 knockdown. Moreover, there is a total absence of clathrin-containing structures completely lacking AP-2 while all the remaining coats still contain a small amount of AP-2. These observations suggest that AP-2 is essential for endocytic coated-pit and coated-vesicle formation. We also find that AP-2 knockdown strongly inhibits light-density lipoprotein (LDL receptor-mediated endocytosis, as long as cells are maintained in complete serum and at 37 degrees C. If cells are first incubated with LDL at 4 degrees C, followed by warming, there is little or no decrease in LDL uptake with respect to control cells. LDL uptake at 37 degrees C is also not affected in AP-2 depleted cells first deprived of LDL by incubation with either serum-starved or LDL-starved cells for 24 hr. The LDL-deprived cells display a significant increase in endocytic structures enriched on deeply invaginated tubes that contain LDL and we suggest that under this condition of stress, LDL might enter through this alternative pathway.These results suggest that AP-2 is essential for endocytic clathrin coated-pit and coated-vesicle formation. They also indicate that under normal conditions, functional endocytic clathrin coated pits are required for LDL internalization. We also show that under certain conditions of stress, cells can upregulate alternative endocytic structures

    2016-01-01

    Full Text Available Os Atos Apócrifos dos Apóstolos recontam a tradição dos apóstolos e suas façanhas públicas. Os apóstolos são apresentados em constante conflito com o mundo à sua volta. Eles demonstram o poder do único Deus verdadeiro por meio de milagres, ascetismo e martírio. O cristianismo que eles representam contrasta com as crenças e poder do mundo greco-romano. Esta instância antissocial é reforçada pela mensagem de castidade anunciada pelos apóstolos, a qual interrompe o casamento, e nos conflitos com as autoridades civis e religiosas. Eles têm preocupações apologéticas, missionárias e de edificação, mas rejeitam os ideais culturais e sociais tradicionais em favor de novos ideais. Os Atos Apócrifos também refletem a rede do patronato social e político contemporâneo do Império romano. Eles redefinem o patronato de uma perspectiva cristã e desafiam o sistema estabelecido ao apresentar a Cristo como o verdadeiro patrono, superior aos patronos humanos, incluindo o imperador. A tentativa de reformular as pressuposições estabelecidas é uma característica que define a identidade cristã representada nesta literatura.

  19. Proactive AP Selection Method Considering the Radio Interference Environment

    Science.gov (United States)

    Taenaka, Yuzo; Kashihara, Shigeru; Tsukamoto, Kazuya; Yamaguchi, Suguru; Oie, Yuji

    In the near future, wireless local area networks (WLANs) will overlap to provide continuous coverage over a wide area. In such ubiquitous WLANs, a mobile node (MN) moving freely between multiple access points (APs) requires not only permanent access to the Internet but also continuous communication quality during handover. In order to satisfy these requirements, an MN needs to (1) select an AP with better performance and (2) execute a handover seamlessly. To satisfy requirement (2), we proposed a seamless handover method in a previous study. Moreover, in order to achieve (1), the Received Signal Strength Indicator (RSSI) is usually employed to measure wireless link quality in a WLAN system. However, in a real environment, especially if APs are densely situated, it is difficult to always select an AP with better performance based on only the RSSI. This is because the RSSI alone cannot detect the degradation of communication quality due to radio interference. Moreover, it is important that AP selection is completed only on an MN, because we can assume that, in ubiquitous WLANs, various organizations or operators will manage APs. Hence, we cannot modify the APs for AP selection. To overcome these difficulties, in the present paper, we propose and implement a proactive AP selection method considering wireless link condition based on the number of frame retransmissions in addition to the RSSI. In the evaluation, we show that the proposed AP selection method can appropriately select an AP with good wireless link quality, i.e., high RSSI and low radio interference.

    2003-01-01

    The Westinghouse AP1000 Program is aimed at implementing the AP1000 plant to provide a further major improvement in plant economics while maintaining the passive safety advantages established by the AP600. An objective is to retain to the maximum extent possible the plant design of the AP600 so as to retain the licensing basis, cost estimate, construction schedule, modularization scheme, and the detailed design from the AP600 program. Westinghouse and the US Nuclear Regulatory Commission staff have embarked on a program to complete Design Certification for the AP1000 by 2004. A pre-certification review phase was completed in March 2002 and was successful in establishing the applicability of the AP600 test program and AP600 safety analysis codes to the AP1000 Design Certification. On March 28, 2002, Westinghouse submitted to US NRC the AP1000 Design Control Document and Probabilistic Risk Assessment, thereby initiating the formal design certification review process. The results presented in these documents verify the safety performance of the API 000 and conformance with US NRC licensing requirements. Plans are being developed for implementation of a series of AP1000 plants in the US. Key factors in this planning are the economics of AP1000, and the associated business model for licensing, constructing and operating these new plants. Similarly plans are being developed to get the AP1000 design reviewed for use in the UK. Part of this planning has been to examine the AP1000 design relative to anticipated UK safety and licensing issues. (author)

    1999-01-01

    As part of the cooperative US Department of Energy (DOE) Advanced Light Water Reactor (ALWR) Program and the Electric Power Research Institute (EPRI), the Westinghouse AP600 team has developed a simplified, safe, and economic 600-megawatt plant to enter into a new era of nuclear power generation. Designed to satisfy the standards set by DOE and defined in the ALWR Utility Requirements Document (URD), the Westinghouse AP600 is an elegant combination of innovative safety systems that rely on dependable natural forces and proven technologies. The Westinghouse AP600 design simplifies plant systems and significant operation, inspections, maintenance, and quality assurance requirements by greatly reducing the amount of valves, pumps, piping, HVAC ducting, and other complex components. The AP600 safety systems are predominantly passive, depending on the reliable natural forces of gravity, circulation, convection, evaporation, and condensation, instead of AC power supplies and motor-driven components. The AP600 provides a high degree of public safety and licensing certainty. It draws upon 40 years of experience in light water reactor components and technology, so no demonstration plant is required. During the AP600 design program, a comprehensive test program was carried out to verify plant components, passive safety systems components, and containment behavior. When the test program was completed at the end of 1994, the AP600 became the most thoroughly tested advanced reactor design ever reviewed by the US Nuclear Regulatory Commission (NRC). The test results confirmed the exceptional behavior of the passive systems and have been instrumental in facilitating code validations. Westinghouse received Final Design Approval from the NRC in September 1998. (author)

  4. NF-κB/AP-1-Targeted Inhibition of Macrophage-Mediated Inflammatory Responses by Depigmenting Compound AP736 Derived from Natural 1,3-Diphenylpropane Skeleton

    Full Text Available AP736 was identified as an antimelanogenic drug that can be used for the prevention of melasma, freckles, and dark spots in skin by acting as a suppressor of melanin synthesis and tyrosinase expression. Since macrophage-mediated inflammatory responses are critical for skin health, here we investigated the potential anti-inflammatory activity of AP736. The effects of AP736 on various inflammatory events such as nitric oxide (NO/prostaglandin (PG E2 production, inflammatory gene expression, phagocytic uptake, and morphological changes were examined in RAW264.7 cells. AP736 was found to strongly inhibit the production of both NO and PGE2 in lipopolysaccharide- (LPS- treated RAW264.7 cells. In addition, AP736 strongly inhibited both LPS-induced morphological changes and FITC-dextran-induced phagocytic uptake. Furthermore, AP736 also downregulated the expression of multiple inflammatory genes, such as inducible NO synthase (iNOS, cyclooxygenase- (COX- 2, and interleukin- (IL- 1β in LPS-treated RAW264.7 cells. Transcription factor analysis, including upstream signalling events, revealed that both NF-κB and AP-1 were targeted by AP736 via inhibition of the IKK/IκBα and IRAK1/TAK1 pathways. Therefore, our results strongly suggest that AP736 is a potential anti-inflammatory drug due to its suppression of NF-κB-IKK/IκBα and AP-1-IRAK1/TAK1 signalling, which may make AP736 useful for the treatment of macrophage-mediated skin inflammation.

En dicha obra el señor Williams cataloga -entre muchas otras de distintas regiones de la Amazonia peruana-- un buen numero de plantas leñosas coleccionadas por él en la hacienda "La Victoria", muy cerca de Leticia, haciéndolas figurar como del Perú. Esto se debe a que en la época que Williams visito aquella región hoy colombiana -a mediados de 1929- no se había perfeccionado todavía, o mejor dicho, no se había puesto en práctica (aunque ya estaba promulgado solemnemente el tratado de fronteras entre Colombia y el Perú que puso fin al litigio que estos dos países sostuvieron por más de un siglo sobre una gran parte del territorio selvoso que se extiende entre los ríos Caquetá y Amazonas. Digo que no se había puesto en practica dicho tratado porque, si bien se firmó el 24 de marzo de 1922 y se promulgo el 31 de marzo de 1938, sólo vino a ejecutarse in situ el 17 de agosto de 1930, después de localizada y amojonada la frontera, mediante la formalidad del acto de entrega y de recibo de los territorios que les tocó definitivamente a un país y al otro. Fue, pues, un año después de la visita de Williams a dicha región cuando la bandera y las autoridades colombianas reemplazaron efectivamente a las peruanas en el llamado "Trapecio Amazónico", cuya población principal es Leticia, sobre el rio Amazonas.

    2017-06-25

    In this paper, online minimization of vertical beam sizes along the APS (Advanced Photon Source) storage ring is presented. A genetic algorithm (GA) was developed and employed for the online optimization in the APS storage ring. A total of 59 families of skew quadrupole magnets were employed as knobs to adjust the coupling and the vertical dispersion in the APS storage ring. Starting from initially zero current skew quadrupoles, small vertical beam sizes along the APS storage ring were achieved in a short optimization time of one hour. The optimization results from this method are briefly compared with the one from LOCO (Linear Optics from Closed Orbits) response matrix correction.

  11. K-AP: Generating specified K clusters by efficient Affinity Propagation

    KAUST Repository

    Zhang, Xiangliang

    2010-12-01

    The Affinity Propagation (AP) clustering algorithm proposed by Frey and Dueck (2007) provides an understandable, nearly optimal summary of a data set. However, it suffers two major shortcomings: i) the number of clusters is vague with the user-defined parameter called self-confidence, and ii) the quadratic computational complexity. When aiming at a given number of clusters due to prior knowledge, AP has to be launched many times until an appropriate setting of self-confidence is found. The re-launched AP increases the computational cost by one order of magnitude. In this paper, we propose an algorithm, called K-AP, to exploit the immediate results of K clusters by introducing a constraint in the process of message passing. Through theoretical analysis and experimental validation, K-AP was shown to be able to directly generate K clusters as user defined, with a negligible increase of computational cost compared to AP. In the meanwhile, K-AP preserves the clustering quality as AP in terms of the distortion. K-AP is more effective than k-medoids w.r.t. the distortion minimization and higher clustering purity. © 2010 IEEE.

    2006-01-01

    Full text of publication follows: The AP1000 is the only Generation III+ reactor to receive Final Design Approval (FDA) from the Nuclear Regulatory Commission, and is expected to receive its Design Certification by the end of the year. Building on the proven features of current generation nuclear plants, the AP1000 combines experience with innovation into a design that surpasses current standards of safety and reliability. Use of passive safety features results in a simpler and more compact design that enhances safety, simplifies O and M requirements, and reduces capital and operating costs. At 1117 Mwe, the AP1000 is well suited for almost any grid system and will be fully competitive with combined-cycle gas and comparable fossil fuel plants. The AP1000 is ready to help launch a renaissance in new nuclear plant construction throughout the world. Maturity of Design: In excess of 1300 man-years and $400 million in development funding have been expended on the AP1000. It has undergone extensive, part scale testing at the system, sub-system and component level, in addition to a series of part scale integrated tests. The AP1000 is the most analyzed of the next generation reactors. Simplicity of Design/Economics: The AP1000 uses simplified and innovative passive safety systems to an unprecedented extent. Simplified passive safety systems provide reliable operation, reduced capital costs, and enhanced plant safety with large plant operating margins. The AP1000 features improved reliability through simplicity rather than addition of redundant safety trains. This simpler design is easier and less costly to operate and maintain than larger, more complex plants, while less equipment and smaller buildings translate into lower capital costs and shorter construction durations. After construction, economic benefit will be found in reduced operating and maintenance costs, largely due to reduced operating and maintenance staffing requirements. Construction aspects

    APS is a part of power supply system which provides the high voltage, high current to the anode of electron beam in the irradiation facility in KAERI. This APS had been used in turn-key base for 10 years, and frequently the Russian scientists had visited to repair this machine. In Summer the humid air had been supplied to dissipate the heat of APS. There is a big and high frequency noise around the transformer in the mutation room. So we stopped the irradiation works and analyzed and repaired the APS. The main course of the problem is the deterioration of IGBT and thyristors which are components of phase controller. We replaced this by new one and APS is now operating well

    The APS accelerator control system is a distributed system consisting of operator interfaces, a network, and computer-controlled interfaces to hardware. This implementation of a control system has come to be called the open-quotes Standard Model.close quotes The operator interface is a UNDC-based workstation with an X-windows graphical user interface. The workstation may be located at any point on the facility network and maintain full functionality. The function of the network is to provide a generalized communication path between the host computers, operator workstations, input/output crates, and other hardware that comprise the control system. The crate or input/output controller (IOC) provides direct control and input/output interfaces for each accelerator subsystem. The network is an integral part of all modem control systems and network performance will determine many characteristics of a control system. This paper will describe the overall APS network and examine the APS control system network in detail. Metrics are provided on the performance of the system under various conditions

    1991-01-01

    This paper presents results of preliminary analyses of the proposed Westinghouse Electric Corporation AP600 design. AP600 is a two loop, 600 MW (e) pressurized water reactor (PWR) arranged in a two hot leg, four cold leg nuclear steam supply system (NSSS) configuration. In contrast to the present generation of PWRs it is equipped with passive emergency core coolant (ECC) systems. Also, the containment and the safety systems of the AP600 interact with the reactor coolant system and each other in a more integral fashion than present day PWRs. The containment in this design is the ultimate heat sink for removal of decay heat to the environment. Idaho National Engineering Laboratory (INEL) has studied applicability of the RELAP5 code to AP600 safety analysis and has developed a model of the AP600 for the Nuclear Regulatory Commission. The model incorporates integral modeling of the containment, NSSS and passive safety systems. Best available preliminary design data were used. Nodalization sensitivity studies were conducted to gain experience in modeling of systems and conditions which are beyond the applicability of previously established RELAP5 modeling guidelines or experience. Exploratory analyses were then undertaken to investigate AP600 system response during postulated accident conditions. Four small break LOCA calculations and two large break LOCA calculations were conducted

    Full Text Available La Alianza del Pacífico (AP es un área de integración de interés en las relaciones internacionales. No obstante, existe un vacío en la literatura sobre las ventajas de ésta para la política exterior de Colombia. Este artículo busca analizar las ventajas de la AP para Colombia. Se defiende la idea que la AP ofrece ventajas para la inserción internacional de Colombia basadas tanto en las características de esa área de integración como en las oportunidades que ofrece para su política exterior. La AP es un área de integración que tiene en sus instituciones una agenda definida de integración, la cosecha temprana de las negociaciones, el seguimiento a las cumbres y una presidencia pro témpore eficaz. Por otra parte, le ofrece a Colombia un área de integración sin tensiones con otros actores, instrumentos para diversificar sus relaciones con el mundo y una opción de liderazgo regional desde la persuasión.

    A mixed methods study conducted over three phases (Phase I – scoping exercise, Phase II – questionnaire and Phase III – semi-structured interviews) aimed to explore the role and integration of the assistant practitioner (AP) practitioner in radiography from the AP perspective. Findings of the overall study are presented across a range of articles where this publication only presents the findings in relation to the training and education of APs from all three phases. Results showed the educational routes undertaken by APs in radiography during training. Training whilst working in the clinical department has highlighted a number of key issues relating to educational pathways and delivery methods. Findings showed that APs felt that more could be done to prepare the individual for clinical practice thereby increasing their confidence and facilitating role development. Results also identified a number of challenges in the training and education of APs in radiography. Clear routes of progression and career pathways are not available to APs in radiography. In conclusion the findings suggest the need for a review of existing educational programmes and future standardisation. The need exists to clarify the justifiable methods of training and differentiate between recognised educational qualifications to enable informed career development decisions by APs and their employers

    Antiphospholipid syndrome (APS) is a rare autoimmune disorder. It can be secondary to systemic lupus erythematosus (SLE) or occur in the absence of autoimmune disease. The hallmark of this so-called primary APS is the presence of circulating antiphospholipid antibodies. Renal involvement in primary APS is caused by thrombosis within the renal vasculature. Recently, nonthrombotic glomerulonephritic renal lesions have been described in primary APS as a new histological entity. We here report a patient with primary APS in whom both lesion types were present. A 58-year-old Caucasian man with no significant past medical history presented to our nephrology unit with diffuse edema. Urinalysis showed proteinuria exceeding 400 mg/dL. The autoantibody panel (p-ANCA, c- ANCA, anti-nucleus, anti-DS-DNA) was negative except for anticardiolipin antibodies, which tested positive in two different samples. The diagnostic workup included a kidney biopsy that revealed thrombotic lesions compatible with primary APS and a typical pattern of focal segmental glomerulosclerosis. The kidney is a major target in APS but the exact mechanism underlying the pathogenesis of APS nephropathy has been poorly recognized. The use of kidney biopsy is a fundamental diagnostic tool in this setting, with possible implications also from a prognostic and therapeutic viewpoint.

    We report two siblings with infantile onset seizures, severe developmental delay and spastic paraplegia, in whom whole-genome sequencing revealed compound heterozygous mutations in the AP4S1 gene, encoding the σ subunit of the adaptor protein complex 4 (AP-4). The effect of the predicted loss-of-function variants (p.Gln46Profs*9 and p.Arg97*) was further investigated in a patient's fibroblast cell line. We show that the premature stop mutations in AP4S1 result in a reduction of all AP-4 subunits and loss of AP-4 complex assembly. Recruitment of the AP-4 accessory protein tepsin, to the membrane was also abolished. In retrospect, the clinical phenotype in the family is consistent with previous reports of the AP-4 deficiency syndrome. Our study reports the second family with mutations in AP4S1 and describes the first two patients with loss of AP4S1 and seizures. We further discuss seizure phenotypes in reported patients, highlighting that seizures are part of the clinical manifestation of the AP-4 deficiency syndrome. We also hypothesize that endosomal trafficking is a common theme between heritable spastic paraplegia and some inherited epilepsies. PMID:25552650

    The Electric Power Research Institute is spearheading an effort to develop utility requirements for the Advanced Light Water Reactor (ALWR) plants which will become the next generation nuclear power plants for the U.S. This EPRI ALWR Program involves utilities, the U.S. Department of Energy, the U.S. Nuclear Regulatory Commission, and various industry suppliers. The ALWR Program is aimed at ALWR plants which incorporate step improvements in safety, reliability, operability and power generation costs. As part of the ALWR efforts, a Westinghouse team is conducting conceptual design development of a PWR plant design called the AP600, reflecting advanced passive safety features and the chosen 600 MWe plant output. The AP600 conceptual design provides significant improvements while employing proven component technology. This paper describes the basic reactor and primary coolant system features, the passive safety system features, and plant arrangement/construction features of AP600

La forma de denominar a España denota una concepción profunda de dicha comunidad que puede ir desde la percepción meramente administrativa del país hasta visiones más afectivas. En este artículo analizamos el discurso sobre España de los dos principales partidos que han gobernado este país desde 1977 hasta 2011 (PSOE y AP-PP. Para ello se utiliza el análisis de contenido de programas electorales asistido por ordenador, mediante una técnica mixta de auto-codificación de palabras clave y posterior re-codificación manual. Asumiendo que las preferencias ideológicas de los partidos sobre el nacionalismo español se traducen en la utilización de diferentes palabras o términos léxicos para designar a España, llevamos a cabo análisis de frecuencias del lenguaje utilizado por ambos partidos. Los resultados muestran una renuncia paulatina por parte del PSOE a explicitar la dimensión comunitaria o afectiva de España, frente a un interés manifiesto por aclarar su visión sobre la organización territorial del estado, resultando ambas tendencias en un descenso global del discurso que el partido socialista ha dedicado a España en sus programas electorales, especialmente notable desde el año 2000. Paralelamente, el aumento de las referencias a España como comunidad política en los programas electorales de AP-PP, especialmente notable desde 1996, derivan en un cambio de tendencias evidente desde 2004.

    In recent years, both domestic and foreign utilities have turned to the standardized Westinghouse AP1000 plant design in satisfying their near - and long-term - sustainable energy needs. As direct support to these actions, licensing the AP1000 design has played a significant role by providing one of the fundamental bases in clearing regulatory hurdles leading to the start of new plant construction. Within the U.S. alone, Westinghouse AP1000 licensing activities have reached unprecedented milestones with the approvals of both AP1000 Design Certification and Southern Company's combined construction permit and operating license (COL) application directly supporting the construction of two new nuclear plants in Georgia. Further COL application approvals are immediately pending for an additional two AP1000 plants in South Carolina. And, across the U.S. nuclear industry spectrum, there are 10 other COL applications under regulatory review representing some 16 new plants at 10 sites. In total, these actions represent the first wave of new plant licensing under the regulatory approval process since 1978. Fundamental to the Nuclear Regulatory Commission's AP1000 Design Certification is the formal recognition of the AP1000 passive safety design through regulatory acceptance rulemaking. Through recognition and deployment of the AP1000 Design Certification, the utility licensee / operator of this reactor design are now offered an opportunity to use a simplified 'one-step' combined license process, thereby managing substantial back-end construction schedule risk from regulatory and intervention delays. Application of this regulatory philosophy represents both acceptance and encouragement of standardized reactor designs like the AP1000. With the recent AP1000 Design Certification and utility COL acceptances, the fundamental licensing processes of this philosophy have successfully proven the attainment of significant milestones with the next stage licensing actions directed

    The Advanced Photon Source (APS) is a third-generation 7-GeV synchrotron radiation source. The precision measurement of beam current is a challenging task in high energy accelerators, such as the APS, with a wide range of beam parameters and complicated noise, radiation, and thermal environments. The beam pulses in the APS injector and storage ring have charge ranging from 50pC to 25nC with pulse durations varying from 30ps to 30ns. A total of nine non- intercepting beam current monitors have been installed in the APS facility (excluding those in the linac) for general current measurement. In addition, several independent current monitors with specially designed redundant interlock electronics are installed for personnel safety and machine protection. This paper documents the design and development of current monitors in the APS,. discusses the commissioning experience in the past year, and presents the results of recent operations

    On 24th of July 2007 Westinghouse Electric Co. signed landmark contracts with China's State Nuclear Power Technology Corporation (SNPTC), to provide four AP1000 nuclear power plants in China. The AP1000 is a two-loop 1117 MWe Pressurized Water Reactor (PWR). It is based on proven technology, but with an emphasis on safety features that rely on natural driving forces, such as pressurized gas, gravity flow, natural circulation flow and convection. Ansaldo Nucleare has provided a significant support to the passive plant technology development and, starting from 2000, is cooperating with Westinghouse to development of the AP1000 Plant. In the frame of the AP1000 Chinese agreement, Ansaldo Nucleare, in Joint Venture with Mangiarotti Nuclear, has signed a contract with Westinghouse for the design and the supply of innovative components to be installed in the first AP1000 unit to be constructed at the Sanmen site. The contract includes: the design of the steel containment vessel, preparation of construction and fabrication, specifications, design and supply of SCV mechanical penetrations, air locks and equipment hatches. Moreover, Ansaldo Nucleare is in charge of the final design of the AP1000 PRHR-HX and together with Mangiarotti Nuclear will supply the component for the Sanmen Unit 1 NPP. The paper presents an overview of the design and manufacturing activities performed by Ansaldo Nucleare and its partners for the AP1000 plant in China. (authors)

    Many interacting proteins regulate and/or assist the activities of RAD51, a recombinase which plays a critical role in both DNA repair and meiotic recombination. Yeast two-hybrid screening of a human testis cDNA library revealed a new protein, RAD51AP2 (RAD51 Associated Protein 2), that interacts strongly with RAD51. A full-length cDNA clone predicts a novel vertebrate specific protein of 1159 residues, and the RAD51AP2 transcript was observed only in meiotic tissue (i.e. adult testis and fetal ovary), suggesting a meiotic-specific function for RAD51AP2. In HEK293 cells the interaction of RAD51 with an ectopically-expressed recombinant large fragment of RAD51AP2 requires the C-terminal 57 residues of RAD51AP2. This RAD51-binding region shows 81% homology to the C-terminus of RAD51AP1/PIR51, an otherwise totally unrelated RAD51-binding partner that is ubiquitously expressed. Analyses using truncations and point mutations in both RAD51AP1 and RAD51AP2 demonstrate that these proteins use the same structural motif for RAD51 binding. RAD54 shares some homology with this RAD51-binding motif, but this homologous region plays only an accessory role to the adjacent main RAD51-interacting region, which has been narrowed here to 40 amino acids. A novel protein, RAD51AP2, has been discovered that interacts with RAD51 through a C-terminal motif also present in RAD51AP1.

    Passive safety actions are considered as main measures under severe accident in AP1000 power plant. However, risk is still existed. According to PSA, several probable scenarios for AP1000 nuclear power plant are analyzed in this paper with MAAP the severe accident analysis code. According to the analysis results, several deficiencies of AP1000 severe accident management are found. The long term cooling and containment depressurization capability for AP1000 power plant appear to be most important factors under such accidents. Then, several temporary strategies for AP1000 power plant are suggested, including PCCWST temporary water supply strategy after 72h, temporary injection strategy for IRWST, hydrogen relief action in fuel building, which would improve the safety of AP1000 power plant. At last, assessments of effectiveness for these strategies are performed, and the results are compared with analysis without these strategies. The comparisons showed that correct actions of these strategies would effectively prevent the accident process of AP1000 power plant. (author)

    Trichoderma spp and Gliocladium spp have been reported as control agents of some of the fungi that cause root rot diseases in various crops. Despite this potential the there is no information on their ecology in tropical soils. This study was conducted at the Palma de Vino farm, La Dorada, Caldas with the aim of contributing to the understanding of their ecology in their natural habitat in the tropics. Representative soil and rhizosphere samples were collected and analyzed for some physical, chemical, and biological properties. The results showed clearly that: 1) both genera, form part of the native microflora of those soils. 2) The Trichoderma spp population fluctuated between 5.7x10 2 and 6.4x10 3 and between 7.4x10 2 and 2x10 4 UFC g - 1 in the soil and rhizoplane, respectively; the Gliocladium spp population could not be estimated, probably due to their low numbers. 3) Within the genus Trichoderma the species T. Hamatum, T. Harzianum, and T. Koningu could be identified. 4) The Trichoderma spp populations, especially those from de rhizoplane, showed a clear relation with de soil pH. As far as we know, these results represent the first source of information on the ecology of these two agronomic important fungi, under tropical conditions

    In the past years the development of an artificial pancreas (AP) has made great progress and many activities are ongoing in this area of research. The major step forward made in the last years was moving the evaluation of AP systems from highly controlled experimental conditions to daily life conditions at the home of patients with diabetes; this was also the aim of the European Union-funded AP@home project. Over a time period of 5 years a series of clinical studies were performed that culminated in 2 "final studies" during which an AP system was used by patients in their home environment for 2 or 3 months without supervision by a physician, living their normal lives. Two different versions of the AP system developed within this project were evaluated. A significant improvement in glycated hemoglobin was observed during closed-loop conditions despite the fact that during the control period the patients used the best currently available therapeutic option. In addition, a "single-port AP system" was developed within the project that combines continuous glucose monitoring and insulin infusion at a single tissue site. By using such a combined device the patients not only have to carry one less device around, the number of access points through the skin is also reduced from 2 to 1. In summary, close cooperation of 12 European partners, both academic centers and industry, enabled the development and evaluation of AP systems under daily life conditions. The next step is to develop these into products in cooperation with commercial partners. © 2016 Diabetes Technology Society.

  12. NECAPs are negative regulators of the AP2 clathrin adaptor complex.

    Eukaryotic cells internalize transmembrane receptors via clathrin-mediated endocytosis, but it remains unclear how the machinery underpinning this process is regulated. We recently discovered that membrane-associated muniscin proteins such as FCHo and SGIP initiate endocytosis by converting the AP2 clathrin adaptor complex to an open, active conformation that is then phosphorylated (Hollopeter et al., 2014). Here we report that loss of ncap-1 , the sole C. elegans gene encoding an adaptiN Ear-binding Coat-Associated Protein (NECAP), bypasses the requirement for FCHO-1. Biochemical analyses reveal AP2 accumulates in an open, phosphorylated state in ncap-1 mutant worms, suggesting NECAPs promote the closed, inactive conformation of AP2. Consistent with this model, NECAPs preferentially bind open and phosphorylated forms of AP2 in vitro and localize with constitutively open AP2 mutants in vivo. NECAPs do not associate with phosphorylation-defective AP2 mutants, implying that phosphorylation precedes NECAP recruitment. We propose NECAPs function late in endocytosis to inactivate AP2. © 2018, Beacham et al.

    The AP1000 plant, which is a 1100 MWe class pressurized water reactor with passive safety features, is designed around a conventional 2 loop, 2 steam generator primary system configuration with 2 hot legs, 4 reactor coolant pumps directly mounted in the steam generator lower head and 4 cold legs. A particular feature of AP1000 is its modular construction to minimize the time and cost of construction. Modular construction allows activities to be run in parallel, it allows more activities to be performed in a controlled factory instead of in the field, and it provides a better level of quality. The AP1000 plant design includes 106 structural modules and 52 mechanical modules. Structural modules include all penetrations for piping, cable trays, HVAC duct runs, and all reinforcement for pipe, equipment hangers, and supports. Structural modules are shipped in sub-modules to support transportation by rail or truck or barge. Mechanical modules contain equipment such as pumps, tanks, heat exchangers, air-handling units, and filters along with interconnecting pipes, valves, instruments, wiring and support services. Modular construction requires strong coordination between engineering, supply chain and construction. A total of 8 AP1000 units are currently under construction in China and in the United States. The lessons learned and best practices of each new AP1000 construction are systematically incorporated into the standard design. (A.C.)

    The Advanced Photon Source is in the process of upgrading its storage ring from a double-bend to a multi-bend lattice as part of the APS Upgrade Project (APS-U). A swap-out injection scheme is planned for the APS-U to keep a constant beam current and to enable a small dynamic aperture. A septum magnet with a minimum thickness of 2 mm and an injection field of 1.06 T has been designed, delivering the required total deflecting angle is 89 mrad with a ring energy of 6 GeV. The stored beam chamber has an 8 mm x 6 mm super-ellipsoidal aperture. The magnet is straight; however, it is tilted in yaw, roll, and pitch from the stored beam chamber to meet the on axis swap out injection requirements for the APS-U lattice. In order to minimize the leakage field inside the stored beam chamber, four different techniques were utilized in the design. As a result, the horizontal deflecting angle of the stored beam was held to only 5 µrad, and the integrated skew quadrupole inside the stored beam chamber was held to 0.09 T. The detailed techniques that were applied to the design, field multipoles, and resulting trajectories of the injected and stored beams are reported.

    The development of an artificial pancreas (AP) made huge strides from 2006 to 2008 and a large number of activities are going on in this area of research. Until now, most AP systems under development were tested only under highly controlled conditions. The aim of our project, funded by the European Union, is to develop an AP system to such a level that it can be studied under daily life conditions at the home of patients with diabetes (hence AP@home). Based on a subcutaneous-subcutaneous closed-loop strategy (i.e., glucose sensing and insulin infusion in the subcutaneous tissue), two different approaches will be taken to achieve this aim: a two-port AP system and a single-port AP system. The two-port AP system will use off-the-shelf-components for the glucose sensor and insulin pump in combination with closed-loop algorithms generated in Europe. As to the single-port AP system, two different innovative single-port systems will be developed; in this case, continuous glucose monitoring and insulin infusion will take place via a single catheter. The first clinical trials with the two-port AP system under controlled clinical conditions have started and good progress has been made in the development of the single-port AP systems. We believe that our consortium of 12 European partners, which builds on existing achievements and close cooperation between academic centers and industry, can contribute substantially to the development of an AP system that can be used by patients in daily life. © 2011 Diabetes Technology Society.

    In the U.S., conditions are becoming more favorable for considering the nuclear option again for new baseload generation. While oil and natural gas prices have risen, the cost of operating the existing fleet of nuclear plants has decreased. Furthermore, an advanced 1000 MWe nuclear plant that will be even more cost-competitive with fossil fuels and natural gas will be available by 2005. Westinghouse, in an effort to further improve on the AP600's cost competitiveness, has developed the AP1000, a two-loop, 1000 MWe, advanced pressurized water reactor (PWR) with passive safety features and extensive plant simplifications to enhance the construction, operation, and maintenance. Like the AP600, the AP1000 uses proven technology that builds on over 30 years of operating PWR experience. Westinghouse has completed design studies that demonstrate that it is feasible to increase the power output of the AP600 to at least 1000 MWe, maintaining its current design configuration and licensing basis. To maximize the cost savings, the AP1000 has been designed within the space constraints of the AP600, while retaining the credibility of proven components and substantial safety margins. The affect on the plant's overnight cost of the increased major components that is required to uprate the AP600 to 1000 MWe is small. This overall cost addition is on the order of 11 percent, while the overall power increase is almost 80 percent. This paper describes the changes made to uprate the AP600 and gives an overview of the plant design. (author)

    2001-01-01

    In order to provide broader scientific recognition and to advance the science of shock compressed condensed matter, a group of American Physical Society (APS) members worked within the Society to make this field an active part of the APS. Individual papers were presented at APS meetings starting in the 1940's and shock wave sessions were organized starting with the 1967 Pasadena meeting. Shock wave topical conferences began in 1979 in Pullman, WA. Signatures were obtained on a petition in 1984 from a balanced cross-section of the shock wave community to form an APS Topical Group (TG). The APS Council officially accepted the formation of the Shock Compression of Condensed Matter (SCCM) TG at its October 1984 meeting. This action firmly aligned the shock wave field with a major physical science organization. Most early topical conferences were sanctioned by the APS while those held after 1992 were official APS meetings. The topical group organizes a shock wave topical conference in odd numbered years while participating in shock wavehigh pressure sessions at APS general meetings in even numbered years

  11. Kinetic properties of ATP sulfurylase and APS kinase from Thiobacillus denitrificans.

    Gay, Sean C; Fribourgh, Jennifer L; Donohoue, Paul D; Segel, Irwin H; Fisher, Andrew J

    2009-09-01

    The Thiobacillus denitrificans genome contains two sequences corresponding to ATP sulfurylase (Tbd_0210 and Tbd_0874). Both genes were cloned and expressed protein characterized. The larger protein (Tbd_0210; 544 residues) possesses an N-terminal ATP sulfurylase domain and a C-terminal APS kinase domain and was therefore annotated as a bifunctional enzyme. But, the protein was not bifunctional because it lacked ATP sulfurylase activity. However, the enzyme did possess APS kinase activity and displayed substrate inhibition by APS. Truncated protein missing the N-terminal domain had APS kinase activity suggesting the function of the inactive sulfurylase domain is to promote the oligomerization of the APS kinase domains. The smaller gene product (Tbd_0874; 402 residues) possessed strong ATP sulfurylase activity with kinetic properties that appear to be kinetically optimized for the direction of APS utilization and ATP+sulfate production, which is consistent with an enzyme that functions physiologically to produce inorganic sulfate.

  13. Control of sulfate concentration by miR395-targeted APS genes in Arabidopsis thaliana

    2016-04-01

    Full Text Available Sulfur nutrition is crucial for plant growth and development, as well as crop yield and quality. Inorganic sulfate in the soil is the major sulfur source for plants. After uptake, sulfate is activated by ATP sulfurylase, and then gets assimilated into sulfur-containing metabolites. However, the mechanism of regulation of sulfate levels by ATP sulfurylase is unclear. Here, we investigated the control of sulfate levels by miR395-mediated regulation of APS1/3/4. Sulfate was over-accumulated in the shoots of miR395 over-expression plants in which the expression of the APS1, APS3, and APS4 genes was suppressed. Accordingly, reduced expression of miR395 caused a decline of sulfate concentration. In agreement with these results, over-expression of the APS1, APS3, and APS4 genes led to the reduction of sulfate levels. Differential expression of these three APS genes in response to sulfate starvation implied that they have different functions. Further investigation revealed that the regulation of sulfate levels mediated by miR395 depends on the repression of its APS targets. Unlike the APS1, APS3, and APS4 genes, which encode plastid-localized ATP sulfurylases, the APS2 gene encodes a cytosolic version of ATP sulfurylase. Genetic analysis indicated that APS2 has no significant effect on sulfate levels. Our data suggest that miR395-targeted APS genes are key regulators of sulfate concentration in leaves.

    1993-02-01

    Traditional synchrotron sources were designed to produce bending magnet radiation and have proven to be an essential scientific tool. Currently, a new generation of synchrotron sources is being built that will be able to accommodate a large number of insertion device (ID) and high quality bending magnet (BM) sources. One example is the 7-GeV Advanced Photon Source (APS) now under construction at Argonne National Laboratory. The research and development effort at the APS is designed to fully develop the potential of this new generation of synchrotron sources. Of the 40 straight sections in the APS storage ring, 34 will be available for IDs. The remaining six sections are reserved for the storage ring hardware and diagnostics. Although the ring incorporates 80 BMs, only 40 of them can be used to extract radiation. The accelerator hardware shadows five of these 40 bending magnets, so the maximum number of BM sources on the lattice is 35. Generally, a photon beamline consists of four functional sections. The first section is the ID or the BM, which provides the radiation source. The second section, which is immediately outside the storage ring but inside a concrete shielding tunnel, is the front end, which is designed to control, define, and/or confine the x-ray beam. In the case of the APS, the front ends are designed to confine the photon beam. The third section, just outside the concrete shielding tunnel and on the experimental floor, is the first optics enclosure, which contains optics to filter and monochromatize the photon beam. The fourth section of a beamline consists of beam transports, additional optics, and experiment stations to do the scientific investigations. This document describes only the front ends of the APS beamlines

    Full Text Available El emperador romano, Juliano II (331-363, reinó entre 361 y su muerte en 363. Se lo llama "el Apóstata", por su decisión de alejarse de su formación cristiana y su proyecto de regresar a la tradición pagana. Su período de gobierno se caracterizó por diversos conflictos, sobre todo religiosos, entre el cristianismo y el paganismo. Como emperador, Juliano llevará adelante una política religiosa cuyo objetivo era la restauración de la religiosidad tradicional, planteando medidas en contra de los cristianos, situación que finalizará con su joven muerte. En sus obras, apela en muchas ocasiones al concepto de mito, desarrollándolo y caracterizándolo. Juliano plantea una mirada neoplatónica del mito, como un relato creado, lleno de exageraciones, inverosimilitudes, contradicciones, excesos y paradojas. Especialmente, desarrolla la idea del mito como una alegoría, que mantiene ocultas ciertas verdades a los ojos de quienes no están preparados para conocerlas.

    In APS vascular patients, thrombotic recurrences are more frequent than in non-APS thrombotic patients. To better define this clinical setting, a systematic review of the literature after 1999 was performed: 8 cohort studies (including the recent APS Piedmont Cohort) and 6 intervention studies were selected and evaluated. Thrombotic recurrences, bleeding events, therapeutic strategies, antiphospholipid (aPL) profile, inherited and acquired risk factors (when present) were calculated and compared. Emerging risk factors for thrombotic recurrences include withdrawal of oral anticoagulant therapy (OAT), high intensity OAT (INR range 3-4), aPL profile (triple positivity, Miyakis types 1 and 2a profiles) and association with inherited or acquired pro-thrombotic risk factors. Moreover, there are evidences that high risk (mainly for aPL profile) APS vascular patients have a high recurrence rate in spite of correct OAT treatment. Clinical trials in this clinical setting are needed. Copyright © 2012 Elsevier B.V. All rights reserved.

    In recent years, both domestic and foreign utilities have turned to the standardized Westinghouse AP1000 plant design in satisfying their near - and long-term - sustainable energy needs. As direct support to these actions, licensing the AP1000 design has played a significant role by providing one of the fundamental bases in clearing regulatory hurdles leading to the start of new plant construction. Within the U.S. alone, Westinghouse AP1000 licensing activities have reached unprecedented milestones with the approvals of both AP1000 Design Certification and Southern Company's combined construction permit and operating license (COL) application directly supporting the construction of two new nuclear plants in Georgia. Further COL application approvals are immediately pending for an additional two AP1000 plants in South Carolina. And, across the U.S. nuclear industry spectrum, there are 10 other COL applications under regulatory review representing some 16 new plants at 10 sites. In total, these actions represent the first wave of new plant licensing under the regulatory approval process since 1978. Fundamental to the Nuclear Regulatory Commission's AP1000 Design Certification is the formal recognition of the AP1000 passive safety design through regulatory acceptance rulemaking. Through recognition and deployment of the AP1000 Design Certification, the utility licensee / operator of this reactor design are now offered an opportunity to use a simplified 'one-step' combined license process, thereby managing substantial back-end construction schedule risk from regulatory and intervention delays. Application of this regulatory philosophy represents both acceptance and encouragement of standardized reactor designs like the AP1000. With the recent AP1000 Design Certification and utility COL acceptances, the fundamental licensing processes of this philosophy have successfully proven the attainment of significant milestones with the next stage licensing

    The Affect in Play Scale (APS; Russ, 1987, 2004) is one of few reliable, standardized measures of pretend play, yet the fact that it requires videotaping and extensive training to score compromises its clinical utility. In this study, we developed and validated a brief rating version (APS-BR) that does not require videotaping. Construct validity was established by comparing scores from the original APS and the APS-BR using an existing data set of videotaped play (n = 46). We examined associations between scores on the APS-BR and theoretically relevant measures of divergent thinking and emotional memories. Scores on the APS-BR related strongly to those on the APS, and the pattern of correlations for each scale and relevant criterion measures was similar in strength and direction, supporting the APS-BR as an alternate form of the APS. In addition, we completed a pilot study to examine the efficacy of using the APS-BR in its intended in vivo format (n = 28). Results from both studies suggest that the APS-BR is a promising brief measure of children's pretend play that can be substituted for the APS in clinical and research settings.

    The evolution of a hinged moveable jaw with variable morphology is considered a major factor behind the successful expansion of the vertebrates. DLX homeobox transcription factors are crucial for establishing the positional code that patterns the mandible, maxilla and intervening hinge domain, but how the genes encoding these proteins are regulated remains unclear. Herein, we demonstrate that the concerted action of the AP-2α and AP-2β transcription factors within the mouse neural crest is essential for jaw patterning. In the absence of these two proteins, the hinge domain is lost and there are alterations in the size and patterning of the jaws correlating with dysregulation of homeobox gene expression, with reduced levels of Emx, Msx and Dlx paralogs accompanied by an expansion of Six1 expression. Moreover, detailed analysis of morphological features and gene expression changes indicate significant overlap with various compound Dlx gene mutants. Together, these findings reveal that the AP-2 genes have a major function in mammalian neural crest development, influencing patterning of the craniofacial skeleton via the DLX code, an effect that has implications for vertebrate facial evolution, as well as for human craniofacial disorders. © 2018.

    2005-03-01

    Full Text Available Abstract Background Trichomonosis, caused by Trichomonas vaginalis, is the number one, nonviral sexually transmitted infection that has adverse consequences for the health of women and children. The interaction of T. vaginalis with vaginal epithelial cells (VECs, a step preparatory to infection, is mediated in part by the prominent surface protein AP65. The bovine trichomonad, Tritrichomonas foetus, adheres poorly to human VECs. Thus, we established a transfection system for heterologous expression of the T. vaginalis AP65 in T. foetus, as an alternative approach to confirm adhesin function for this virulence factor. Results In this study, we show stable transfection and expression of the T. vaginalis ap65 gene in T. foetus from an episomal pBS-ap65-neo plasmid. Expression of the gene and protein was confirmed by RT-PCR and immunoblots, respectively. AP65 in transformed T. foetus bound to host cells. Specific mAbs revealed episomally-expressed AP65 targeted to the parasite surface and hydrogenosome organelles. Importantly, surface-expression of AP65 in T. foetus paralleled increased levels of adherence of transfected bovine trichomonads to human VECs. Conclusion The T. vaginalis AP65 adhesin was stably expressed in T. foetus, and the data obtained using this heterologous system strongly supports the role of AP65 as a prominent adhesin for T. vaginalis. In addition, the heterologous expression in T. foetus of a T. vaginalis gene offers an important, new approach for confirming and characterizing virulence factors.

    Mutations in the breast cancer susceptibility gene (BRCA1) account for a significant proportion of hereditary breast and ovarian cancers. Cofactor of BRCA1 (COBRA1) was isolated as a BRCA1-interacting protein and exhibited a similar chromatin reorganizing activity to that of BRCA1. However, the biological role of COBRA1 remains largely unexplored. Here, we report that ectopic expression of COBRA1 inhibited activator protein 1 (AP-1) transcriptional activity in transfected cells in a dose-dependent manner, whereas reduction of endogenous COBRA1 with a small interfering RNA significantly enhanced AP-1-mediated transcriptional activation. COBRA1 physically interacted with the AP-1 family members, c-Jun and c-Fos, and the middle region of COBRA1 bound to c-Fos. Lack of c-Fos binding site in the COBRA1 completely abolished the COBRA1 inhibition of AP-1 trans-activation. These findings suggest that COBRA1 may directly modulate AP-1 pathway and, therefore, may play important roles in cell proliferation, differentiation, apoptosis, and oncogenesis

    The EUR (European Utility Requirements) Volume 3 is intended to report the Plant Description, the Compliance Assessment to EUR Volumes 1 and 2, and finally, the Specific Requirements for each specific Nuclear Power Plant Design considered by the EUR. Five subsets of EUR Volume 3, based on EUR Revision B, are already published; all of which are next generation plant designs being developed for Europe beyond 2000. They include : 1) EP1000 - Passive Pressurized Light Water Reactor (3-Loop, 1000 MWe) 2) EPR - Evolutionary Pressurized Light Water Reactor (1500 MWe) 3) BWR90/90+ - Evolutionary Boiling Water Reactor (1400 MWe) 4) ABWR - Evolutionary Boiling Water Reactor (1400 MWe) 5) SWR 1000 - Boiling Water Reactor With Passive Features (1000 MWe) In addition, the following subsets are currently being developed: 1) AP1000 - Passive Pressurized Light Water Reactor (2-Loop, 1117 MWe) 2) VVER AES 92 - Pressurized Water Reactor With Passive Features (1000 MWe) The purpose of this paper is to provide an overview of the program, which started in January 2004 with the EUR group to prepare an EUR Volume 3 Subset for the AP1000 nuclear plant design. The AP1000 EUR compliance assessment, to be performed against EUR Revision C requirements, is an important step for the evaluation of the AP1000 design for application in Europe. The AP1000 compliance assessment is making full use of AP1000 licensing documentation, EPP Phase 2 design activities and EP1000 EUR detailed compliance assessment. As of today, nearly all of the EUR Chapters have been discussed within the EUR Coordination Group. Based on the results of the compliance assessment, it can be stated that the AP1000 design shows a good level of compliance with the EUR Revision C requirements. Nevertheless, the compliance assessment has highlighted areas for where the AP1000 plant deviates from the EUR. The EPP design group has selected the most significant ones for performing detailed studies to quantify the degree of compliance

    Autoimmune polyglandular syndrome type 3 - (APS-3), is defined as the coexistence of autoimmune thyroiditis with other non-ovarian autoimmune diseases without primary adrenal insufficiency. Additionally the definition of APS-3 also includes primary ovarian insufficiency (POI) coexistence with autoimmune thyroiditis. The main goal of that study is to assess the prevalence of APS-3 defined as coexistence of autoimmune thyroiditis with POI in population of 46 XX karyotype women with primary ovarian insufficiency (POI). The second goal is to investigate hormonal profile and insulin sensitivity in women with POI and subgroups of women with APS-3 - POI/APS-3(+) and without APS 3 - POI/APS-3(-). Anthropometric measurements, coexistence of autoimmune diseases, androgens, fasting glucose and insulin, glucose and insulin at 60' and 120' of oral glucose tolerance test (OGTT) and homeostasis model for insulin resistance (HOMA-IR), were determine in 98 patients aged between 18 and 39 with spontaneous 46 XX primary ovarian insufficiency (POI), in 33 POI/APS-3(+), 65 POI/APS-3(-), and 75 healthy controls. Continuous data were summarized by the mean±standard deviation (SD), and categorical data by number (percentages). Data were checked for normality using Shapiro-Wilk test, the comparison between groups were performed using non-parametric Mann-Whitney or Kruskall-Wallis test. Pearson's correlation coefficient was used to assess the relationships between parameters. Statistical significance was defined as p values APS-3(+) and POI/APS-3(-) showed significantly lower serum androgens in comparison to controls. Additionally women with POI/APS-3(+) showed hyperinsulinemia after 1h of OGTT; No significant differences in serum fasting glucose, insulin and during 2h OGTT between groups were observed. The prevalence of APS-3 is 33.7% in patients with spontaneous 46 XX primary ovarian insufficiency. Women with POI, POI/APS-3(+) and POI/APS-3(-) feature lower testosterone, androstendione

    The construction of AP1000 Nuclear Power Plant (NPP) has commenced in China. The AP1000 NPP features a passive design concept and modular construction technology. Based on the management of the construction of current AP1000 NNP, this paper describes the effects on Nuclear Island (NI) construction project management resulting from modular construction technology, as well as new construction techniques and methods. This paper puts forward new requirements for construction schedule management of the nuclear island construction at different levels. The AP1000 NI construction logic features the parallel construction of civil and structural erection as the main approach, with the integrated schedule of module fabrication, assembly and installation as support. The structural modules of AP1000 project are prefabricated in shop, delivered to site as sub-modules and assembled to integrated structural module. The assembled module is transported to the construction site, hoisted and finally set in NI. This paper illustrates how to ensure the construction quality of structural modules by analyzing the interface process and key links in the quality control program, and introduces how to ensure the safety of heavy structural components during various construction phases by evaluating and analyzing the construction safety process. This paper also makes an analysis of the safe environment for the assembly and installation of Containment Vessel, the management of product protection and personnel safety inside the Containment Building during 'Open Top' construction, raises to implement effective protection for the numerous pre-set mechanical modules and equipments, as well as personnel safety protection programs and measures. The modular construction feature of AP1000 NPP design requires technique improvement and management innovation during the NI construction. This paper makes a study and research on the control management of schedule, quality and safety of AP1000 NPP NI

    Full Text Available A eosinofilia sanguínea após o tratamento anti-helmíntico específico se comportou numa amostragem de 57 crianças da seguinte forma: .Na ascaridíase isolada ou associada à trieuríase a hipereosinofilia parasitária ou descia uniformemente após o tratamento, ou houve primeiro uma exacerbação que durava até a terceira semana após a erradicação da, parasitose, descendo em seguida. Em ambos os casos houve normalização do hemograma em dois meses. Na associação ascaridíase/ancilostomíase também são possíveis dois tipos de comportamento da eosinofilia após tratamento eficaz: ou vai diminuindo a hipereosinofilia, logo em seguida à expulsão dos parasitos, ou há no primeiro mês um aumento da hipereosinofilia (geralmente mais acentuado na primeira semana que se segue ao tratamento, para diminuir após o fim do primeiro mês progressivamente até desaparecer. Na estrongiloidíase e na associação ascaridíase/estrongiloidíase há diminuição constante da hipereosinofilia logo após o tratamento e o hemograma se normaliza em cerca de dois meses. Na trieuríase, a hipereosinofilia, aliás já discreta, diminui pouco com o tratamento. Na ancilostomíase e na associação ancilostomíase/trieuríase a hipereosinofilia ou desce após o tratamento gradativo e lentamente, ou primeiro há uma exaltação temporária nas primeiras três semanas após a terapêutica, para diminuir em seguida.

    Diagnosis of antiphospholipid syndrome (APS) is essentially based on the detection of circulating antiphospholipid (aPL) antibodies. Progress have been made on the standardization of tests exploring the presence of aPL as guidelines on coagulation and immunological tests were recently published in the literature. Clinical relevance of aPL profile has come from prospective cohort studies in populations with a homogeneous antibody profile supporting the view that triple positivity is a high risk pattern in patients and carriers. In addition to the classic ones, several other tests have been proposed for the diagnosis of APS. The detection of antibodies directed to domain 1 and 4/5 of β2-Glycoprotein I (β2GP1) were found to be particularly sound. Several issues remain to be addressed. We do not yet know what is the physiological function of β2GP1 and the pathophysiology of thrombosis and pregnancy loss in these patients. Moreover, treatment is poorly defined especially in the case of feared catastrophic APS. Copyright © 2016 Elsevier B.V. All rights reserved.

    Among the diagnostic assays for anti-phospholipid syndrome (APS), lupus anticoagulant (LA) is the strongest predictor of thrombosis; however, it presents several limitations as interference with anticoagulant therapy and poor inter-laboratory agreement. Two-thirds of LA activity is apparently due to antibodies against prothrombin (PT), usually detectable by ELISA. Binding of PT to phosphatidylserine (PS) has been shown to enhance solid-phase anti-PT assay sensitivity. To determine the prevalence of antibodies against PS/PT (aPS/PT) in APS, we tested the semiquantitative QUANTA Lite(®) aPS/PT ELISA in a cohort of 80 APS patients. The prevalence of aPS/PT was 81.3%, rising to 87.6% when considering LA-positive subjects only. We observed a strong correlation between aPS/PT and LA (p = 0.006). To note, APS patients with thrombotic manifestations displayed significantly higher IgG aPS/PT titers compared to 20 aPL asymptomatic carriers (p = 0.012). To rule out a possible cross-reactivity of anti-β2 glycoprotein I antibodies (aβ2GPI) with PS/PT complex, we tested two monoclonal aβ2GPI antibodies and an affinity-purified (AP) polyclonal aβ2GPI IgG obtained from the serum of a patient reacting against both β2GPI and PS/PT. The two monoclonal antibodies did not show any reactivity against PS/PT complex, similarly the AP IgGs did not react toward PS/PT antigen while preserved their aβ2GPI activity. Our findings suggest that aPS/PT are a definite antibody population in APS. Moreover, the good correlation between aPS/PT ELISA and LA may support its use as a surrogate test for LA, particularly useful to overcome the technical limitations of the functional assay.

    Homologous recombination is needed for meiotic chromosome segregation, genome maintenance, and tumor suppression. RAD51AP1 (RAD51 Associated Protein 1) has been shown to interact with and enhance the recombinase activity of RAD51. Accordingly, genetic ablation of RAD51AP1 leads to enhanced sensitivity to and also chromosome aberrations upon DNA damage, demonstrating a role for RAD51AP1 in mitotic homologous recombination. Here we show physical association of RAD51AP1 with the meiosis-specific recombinase DMC1 and a stimulatory effect of RAD51AP1 on the DMC1-mediated D-loop reaction. Mechanistic studies have revealed that RAD51AP1 enhances the ability of the DMC1 presynaptic filament to capture the duplex DNA partner and to assemble the synaptic complex, in which the recombining DNA strands are homologously aligned. We also provide evidence that functional co-operation is dependent on complex formation between DMC1 and RAD51AP1, and that distinct epitopes in RAD51AP1 mediate interactions with RAD51 and DMC1. Finally, we show that RAD51AP1 is expressed in mouse testes, and that RAD51AP1 foci co-localize with a subset of DMC1 foci in spermatocytes. These results suggest that RAD51AP1 also serves an important role in meiotic homologous recombination.

  9. The dyad palindromic glutathione transferase P enhancer binds multiple factors including AP1.

    Glutathione Transferase P (GST-P) gene expression is dominantly regulated by an upstream enhancer (GPEI) consisting of a dyad of palindromically oriented imperfect TPA (12-O-tetradecanoyl-phorbol-13-acetate)-responsive elements (TRE). GPEI is active in AP1-lacking F9 cells as well in AP1-containing HeLa cells. Despite GPEI's similarity to a TRE, c-jun co-transfection has only a minimal effect on transactivation. Antisense c-jun and c-fos co-transfection experiments further demonstrate the lack of a role for AP1 in GPEI mediated trans-activation in F9 cells, although endogenously present AP1 can influence GPEI in HeLa cells. Co-transfection of delta fosB with c-jun, which forms an inactive c-Jun/delta FosB heterodimer that binds TRE sequences, inhibits GPEI-mediated transcription in AP1-lacking F9 cells as well as AP1-containing HeLa cells. These data suggest novel factor(s) other than AP1 are influencing GPEI. Binding studies reveal multiple nucleoproteins bind to GPEI. These factors are likely responsible for the high level of GPEI-mediated transcription observed in the absence of AP1 and during hepatocarcinogenesis.

    Belcher, Nathan Tillman

    This action research study used data from multiple assessments in Mechanics and Electricity and Magnetism to determine the viability of Modeling Instruction as a pedagogy for students in AP Physics C: Mechanics and Electricity and Magnetism. Modeling Instruction is a guided-inquiry approach to teaching science in which students progress through the Modeling Cycle to develop a fully-constructed model for a scientific concept. AP Physics C: Mechanics and Electricity and Magnetism are calculus-based physics courses, approximately equivalent to first-year calculus-based physics courses at the collegiate level. Using a one-group pretest-posttest design, students were assessed in Mechanics using the Force Concept Inventory, Mechanics Baseline Test, and 2015 AP Physics C: Mechanics Practice Exam. With the same design, students were assessed in Electricity and Magnetism on the Brief Electricity and Magnetism Assessment, Electricity and Magnetism Conceptual Assessment, and 2015 AP Physics C: Electricity and Magnetism Practice Exam. In a one-shot case study design, student scores were collected from the 2017 AP Physics C: Mechanics and Electricity and Magnetism Exams. Students performed moderately well on the assessments in Mechanics and Electricity and Magnetism, demonstrating that Modeling Instruction is a viable pedagogy in AP Physics C: Electricity and Magnetism.

    Full Text Available The selective transport of proteins or lipids by vesicular transport is a fundamental process supporting cellular physiology. The budding process involves cargo sorting and vesicle formation at the donor membrane and constitutes an important process in vesicular transport. This process is particularly important for the polarized sorting in epithelial cells, in which the cargo molecules need to be selectively sorted and transported to two distinct destinations, the apical or basolateral plasma membrane. Adaptor protein (AP-1, a member of the AP complex family, which includes the ubiquitously expressed AP-1A and the epithelium-specific AP-1B, regulates polarized sorting at the trans-Golgi network and/or at the recycling endosomes. A growing body of evidence, especially from studies using model organisms and animals, demonstrates that the AP-1-mediated polarized sorting supports the development and physiology of multi-cellular units as functional organs and tissues (e.g., cell fate determination, inflammation and gut immune homeostasis. Furthermore, a possible involvement of AP-1B in the pathogenesis of human diseases, such as Crohn’s disease and cancer, is now becoming evident. These data highlight the significant contribution of AP-1 complexes to the physiology of multicellular organisms, as master regulators of polarized sorting in epithelial cells.

    International Nuclear Information System (INIS)

    2016-09-01

    A severe accident involving several units took place in Japan at Fukushima Daiichi nuclear power plant (NPP) in March 2011. The immediate cause of the accident was an earthquake followed by a tsunami coupled with inadequate provisions against the consequences of such events in the design. Opportunities to improve protection against a realistic design basis tsunami had not been taken. As a consequence of the tsunami, safety equipment and the related safety functions were lost at the plant, leading to core damage in three units and subsequently to large radioactive release. Several studies have already been performed to better understand the accident progression and detailed technical studies are still in progress in Japan and elsewhere. In the meantime, on-going studies on the behaviour of nuclear power plants in very severe situations, similar to Fukushima Daiichi, seek to identify potential vulnerabilities in plant design and operation; to suggest reasonably practicable upgrades; or to recommend enhanced regulatory requirements and guidance to address such situations. Likewise, agencies around the world that are responsible for regulating the design, construction and operation of AP1000 R plants are engaged in similar activities. The MDEP AP1000 R Working Group (AP1000 WG) members consist of members from Canada, China, the United Kingdom and the United States. Since the regulatory review of their AP1000 R applications have not been completed by all of these Countries yet, this paper identifies common preliminary approaches to address potential safety improvements for AP1000 R plants as related to lessons learned from the Fukushima Daiichi accident or Fukushima Daiichi-related issues. In seeking common position, regulators will provide input to this paper to reflect their safety conclusions regarding the AP1000 R design and how the design could be enhanced to address Fukushima Daiichi issues. The common preliminary approaches are organized into five sections

    Persistent postoperative pain (PPP) is a significant clinical problem. Several patient-related risk factors for PPP have been identified, including a previous chronic pain problem, young age, female gender and psychological vulnerability. Intra- and postoperative risk factors include surgical complications such as infections, haematoma, nerve damage and repeated surgery. As the length of hospital stay has been shortened, some patients may be discharged despite ongoing pain and insufficient analgesic medication. The challenge is to identify patients at high risk of developing PPP and to create a targeted care pathway to ensure effective and safe pain treatment especially in the subacute postoperative phase at home. This observational study describes the first two years of the Acute Pain Service Out-Patient Clinic (APS-OPC) at the Helsinki University Hospital. Patient characteristics, known risk factors, and details of treatment of PPP for the first 200 patients referred to our APS-OPC were retrospectively collected from the medical records. The APS-OPC clinic functions in close collaboration with the Multidisciplinary Pain Clinic (MPC), and the number of patients in need of physiotherapist, psychologist or psychiatrist counselling was recorded, as well as the number of patients referred to the MPC for further PPP management. Patients were referred to the APS-OPC from different surgical specialities, the two most common being thoracic and orthopaedic surgery. Seventy per cent of the patients (139/200) presented symptoms indicating neuropathic postsurgical pain. The patients had, on average, five risk factors for PPP. The median time from surgery to the first contact to the APS-OPC was two months, and the median duration of follow-up was 2.8 months (0-16 months). The median number of contacts with APS-OPC was 3 (range 1-14). Every fourth patient needed only one contact to the APS-OPC. Nineteen per cent of the patients had an appointment with the physiotherapist and 20

    Autoimmune Polyglandular Syndrome type 1 (APS-1) is a subtype of the autoimmune polyendocrine syndrome characterized by the simultaneous or sequential dysfunction of multiple endocrine or non-endocrine glands. A clinical diagnosis of APS-1 is typically based on the presence of at least two of three following criteria: chronic mucocutaneous candidiasis, hypoparathyroidism and adrenal insufficiency. The first identified causative mutated gene for APS-1 is autoimmune regulator (AIRE) encoding a critical transcription factor, which is primarily expressed in the medullary thymic epithelial cells (mTECs) for generating central immune tolerance. A wide range of chronic, debilitating complications, with no obvious correlation with genetics, makes a diagnosis of APS-1 challenging early in the disease course. Managing APS-1 is difficult due to its complexity, especially the intricate relationships within manifestations and genetic mutations. The past decades have witnessed dramatic progress in elucidating the function of AIRE and conducting large-scale cohort studies in APS-1. However, no clear evidence-based guidelines have been established in APS-1. In this review, we provide a detailed critical overview of the study history, epidemiology, clinical features, and related mechanisms of autoimmunity in APS-1, as well as currently available therapies for this autoimmune disorder.

    Design of the AP600 advanced nuclear plant man-machine interface system (M-MIS) is guided by the applicable requirements from the Utility Requirements Document (URD). However, the URD has left certain aspects of the M-MIS to be determined by the designer working together with utilities sponsoring the work. This is particularly true in the case of the level of automation to be designed into the M-MIS. Based on experience from currently operating plants, utilities have specified the identity and roles of personnel in the control room, which has led to establishing a number of level of automation issues for the AP600. The key role of automated computerized procedures in the AP600 automation has been determined and resolved. 5 refs

    The AP600 Probabilistic Risk Assessment (PRA) includes detailed models of the plant systems, including the containment and containment systems that would be used to mitigate the consequences of a severe accident. The AP600 PRA includes a level 1 analysis (core damage frequency), and a level 2 analysis (environmental consequences), an assessment of the plant vulnerability to accidents caused by fire or floods, and a seismic margins analysis. Numerous sensitivities are included in the AP600 PRA including one that assumes no credit for non-safety plant systems. The core damage frequency for the AP600 of 1.7E-07/year is small compared with other PRAs performed in the nuclear industry. The AP600 large release frequency of 1.8E-08/year is also small and shows the ability of the containment systems to prevent a large release should a severe accident occur. Analyses of potential consequences to the environment from a severe accident show that a release would be small, and that containment still provides significant protection 24 hours after an assumed accident. Sensitivity analyses show that plant risk (as measured by core damage frequency and large release frequency) is not sensitive to the reliability of operator actions. 6 refs., 1 fig., 1 tab

    The International Sherwood Theory Meeting is a yearly meeting that focuses on the theory of magnetically confined fusion plasmas. There are many topics of common interest in fusion plasma systems and space and astrophysical plasmas. These common topics include such key topics as magnetic reconnection, the dynamo, turbulence and transport and particle heating and acceleration. One of the major participants of the April APS meeting is the APS Division of Astrophysics (DAP). The goal of having the Sherwood Meeting jointly with the April meeting was to promote discussion of topics of common interest in fusion and space and astrophysics. Scientists from the DAP, the Division of Plasma Physics (DPP), the Topical Group on Plasma Astrophysics (GPAP) and Sherwood worked together closely to produce a joint program that addressed areas of common interest. Four sessions of invited talks were sponsored jointly by the DAP, DPP and GPAP on laboratory experiments related to astrophysics. Plasma scientists working in theory and computation play a key role in connecting these laboratory experiments to the very disparate conditions found in fusion and astrophysical systems. Thus, the attendees of the Sherwood Theory meeting were critical to facilitating this effort at cross-disciplinary communication. Noteworthy were the selection of two of the prestigious plenary talks at the joint meeting on plasma topics - one related to the gyrokinetic modeling of turbulence and the other related to the structure of collisionless shocks. It is rare to see even a single plenary talk on plasma physics at the APS April Meeting. There were additional costs associated with hosting a joint meeting. The Office of Fusion Energy Sciences contributed $3000 in partial support of this meeting. This funding covered part of the costs of the poster boards and A. V. equipment that was used in the presentation of nearly 200 scientific papers related to magnetically confined fusion plasmas. The APS waived its

    There is an increasing trend toward understanding the impact of non-Saccharomyces yeasts on the winemaking process. Although Saccharomyces cerevisiae is the predominant species at the end of fermentation, it has been recognized that the presence of non-Saccharomyces species during alcoholic fermentation can produce an improvement in the quality and complexity of the final wines. A previous work was developed for selecting the best combinations between S. cerevisiae and five non-Saccharomyces (Torulaspora delbrueckii, Schizosaccharomyces pombe, Candida stellata, Metschnikowia pulcherrima, and Lachancea thermotolorans) native yeast strains from D.O. “Vinos de Madrid” at the laboratory scale. The best inoculation strategies between S. cerevisiae and non-Saccharomyces strains were chosen to analyze, by real-time quantitative PCR (qPCR) combined with the use of specific primers, the dynamics of inoculated populations throughout the fermentation process at the pilot scale using the Malvar white grape variety. The efficiency of the qPCR system was verified independently of the samples matrix, founding the inoculated yeast species throughout alcoholic fermentation. Finally, we can validate the positive effect of selected co-cultures in the Malvar wine quality, highlighting the sequential cultures of T. delbrueckii CLI 918/S. cerevisiae CLI 889 and C. stellata CLI 920/S. cerevisiae CLI 889 and, mixed and sequential cultures of L. thermotolerans 9-6C combined with S. cerevisiae CLI 889.

  8. Obstetric and vascular APS: same autoantibodies but different diseases?

    Beta2 glycoprotein I (β2GPI)-dependent antiphospholipid antibodies (aPLs) are the main pathogenic autoantibody population and at the same time the laboratory diagnostic tool for the antiphospholipid syndrome (APS). These antibodies are responsible for both the vascular and the obstetric manifestations of the syndrome but the pathogenic mechanisms behind these manifestations are not the same. For example, thrombotic events do not appear to play a major role in APS miscarriages and a direct reactivity of β2GPI-dependent aPLs on decidual and trophoblast cells was reported. A local expression of β2GPI on these tissues was reported both in physiological conditions and in APS women, thus explaining the local tropism of the autoantibodies. The two hit hypothesis was suggested to explain why the vascular manifestations of APS may occur only occasionally in spite of the persistent presence of aPLs. This is not apparently the case for the obstetric variant of the syndrome, making the difference even more striking. A different pathogenesis may also provide the rationale for the well-known fact that the vascular and the obstetric manifestations may occur independently although in a minority of cases.

    Glucocorticoids are widely used to treat inflammatory diseases but have a number of side effects that partly are connected to inhibition of cell proliferation. Glucocorticoids mediated their action by binding to the glucocorticoid receptor. In the present study, we have identified by two-hybrid screens the germinal center-associated protein (GANP) and MCM3-associated protein (MCM3AP), a splicing variant of GANP, as glucocorticoid receptor interacting proteins. GANP and MCM3AP can bind to the MCM3 protein involved in initiation of DNA replication. Glutathione-S-transferase-pull-down and co-immunoprecipitation assays showed that the C-terminal domain of GANP, encompassing MCM3AP, interacts with the ligand-binding domain of the glucocorticoid receptor. Characterization of the intracellular localization of GANP revealed that GANP is shuttling between the nucleus and the cytoplasm. Furthermore, we show that glucocorticoids are unable to inhibit DNA replication in HeLa cells overexpressing MCM3AP suggesting a role for both glucocorticoid receptor and GANP/MCM3AP in regulating cell proliferation

    The upgrade of the Advanced Photon Source (APS) to a Multi-Bend Achromat (MBA) will increase the brightness of the APS by between two and three orders of magnitude. The APS upgrade (APS-U) project includes a list of feature beamlines that will take full advantage of the new machine. Many of the existing beamlines will be also upgraded to profit from this significant machine enhancement. Optics simulations are essential in the design and optimization of these new and existing beamlines. In this contribution, the simulation tools used and developed at APS, ranging from analytical to numerical methods, are summarized. Three general optical layouts are compared in terms of their coherence control and focusing capabilities. The concept of zoom optics, where two sets of focusing elements (e.g., CRLs and KB mirrors) are used to provide variable beam sizes at a fixed focal plane, is optimized analytically. The effects of figure errors on the vertical spot size and on the local coherence along the vertical direction of the optimized design are investigated.

    The long-term survival of lung cancer patients treated with conventional therapies remains poor and therefore the need for novel approaches remains high. This has led to the re-emergence of aerosol delivery as a therapeutic intervention. In this study, glucosylated polyethylenimine (GPEI) was used as carrier to investigate programmed cell death 4 (PDCD4) and PDCD4 mutant (D418A), an eIF4A-binding mutant, on PDCD4-related signaling and activator protein-1 (AP-1) activity in the lungs of AP-1 luciferase reporter mice. After confirming the efficiency of GPEI as a carrier in lungs, the effects of aerosol-delivered PDCD4 were investigated in AP-1 luciferase reporter mice. Aerosol delivery of GPEI/PDCD4 through a nose-only inhalation facilitated the apoptosis of lungs whereas aerosol PDCD4 mutant did not. Also, such aerosol delivery regulated proteins relevant to cell-cycle control and suppressed AP-1 activity. Results obtained by western blot analysis, immunohistochemistry, luciferase assay and deoxynucleotidyl-transferase-mediated nick end labeling study suggest that combined actions such as facilitating apoptosis, controlling cell cycle and suppression of AP-1 activity by PDCD4 may provide useful tool for designing lung tumor prevention and treatment by which PDCD4 functions as a transformation suppressor in the future.

    The AP1000 is a standard design developed by Westinghouse and its partners for an advanced nuclear power plant utilizing passive safety features. It is based on the certified design of the AP600 and has been uprated to 1000 MWe. The plant has five principal building structures; the nuclear island, the turbine building; the annex building; the diesel generator building and the radwaste building. The nuclear island consists of the containment building (the steel containment vessel and the containment internal structures), the shield building, and the auxiliary building. These structures are founded on a common basemat and are collectively known as the nuclear island. This paper describes use of the general purpose finite element program ANSYS [2] in structural analyses and qualification of the AP1000 nuclear island buildings. It describes the modeling of the shield building and the auxiliary building and the series of analyses and the flow of information from the global analyses to the detailed analyses and building qualification.

  13. APS-U LATTICE DESIGN FOR OFF-AXIS ACCUMULATION

    Energy Technology Data Exchange (ETDEWEB)

    2017-06-25

    A 67-pm hybrid-seven-bend achromat (H7BA) lattice is being proposed for a future Advanced Photon Source (APS) multi-bend-achromat (MBA) upgrade project. This lattice design pushes for smaller emittance and requires use of a swap-out (on-axis) injection scheme due to limited dynamic acceptance. Alternate lattice design work has also been performed for the APS upgrade to achieve better beam dynamics performance than the nominal APS MBA lattice, in order to allow off-axis accumulation. Two such alternate H7BA lattice designs, which target a still-low emittance of 90 pm, are discussed in detail in this paper. Although the single-particle-dynamics performance is good, simulations of collective effects indicate that surprising difficulty would be expected accumulating high single-bunch charge in this lattice. The brightness of the 90-pm lattice is also a factor of two lower than the 67-pm H7BA lattice.

    Double-Shell Tank 241-AP-105 is a radioactive waste tank most recently sampled in March of 1993. Sampling and characterization of the waste in Tank 241-AP-105 contributes toward the fulfillment of Milestone M-44-05 of the Hanford Federal Facility Agreement and Consent Order (Ecology, EPA, and DOE, 1993). Characterization is also needed tot evaluate the waste's fitness for safe processing through an evaporator as part of an overall waste volume reduction program. Tank 241-AP-105, located in the 200 East Area AP Tank Farm, was constructed and went into service in 1986 as a dilute waste receiver tank; Tank 241AP-1 05 was considered as a candidate tank for the Grout Treatment Facility. With the cancellation of the Grout Program, the final disposal of the waste in will be as high- and low-level glass fractions. The tank has an operational capacity of 1,140,000 gallons, and currently contains 821,000 gallons of double-shell slurry feed. The waste is heterogeneous, although distinct layers do not exist. Waste has been removed periodically for processing and concentration through the 242-A Evaporator. The tank is not classified as a Watch List tank and is considered to be sound. There are no Unreviewed Safety Questions associated with Tank 241-AP-105 at this time. The waste in Tank 241-AP-105 exists as an aqueous solution of metallic salts and radionuclides, with limited amounts of organic complexants. The most prevalent soluble analytes include aluminum, potassium, sodium, hydroxide, carbonate, nitrate, and nitrite. The calculated pH is greater than the Resource Conservation and Recovery Act established limit of 12.5 for corrosivity. In addition, cadmium, chromium, and lead concentrations were found at levels greater than their regulatory thresholds. The major radionuclide constituent is 137 Cs, while the few organic complexants present include glycolate and oxalate. Approximately 60% of the waste by weight is water

    1996-01-01

    Activity concerning the development of a RELAP5/MOD3 model to simulate the Westinghouse Electric Corporation AP600 is summarized. The aim is to gain initial insight into the capability of RELAP5 to simulate the behavior of AP600 safety features. A-loss-of-normal-feedwater event is studied. Of the transients that must be investigated, this transient has been chosen to be one of the most relevant because the response of the AP600 to a loss-of-normal-feedwater event differs significantly from that of current pressurized water reactors in the extensive use of passive safety features peculiar to the AP600. Also, strong interactions among the AP600 safety systems, which should be further analyzed to permit full optimization of the system actuation logic and operation, are shown. Finally, a loss of normal feedwater without reactor scram, performed to investigate short-term plant behavior, shows that the pressure peak is affected by critical discharge flow coefficients applied to the pressurizer safety valves, while a relatively small reduction of the pressure peak is observed when both heat exchangers of the passive heat removal system are operating as opposed to the case in which only one is available. The data used for this study are derived from the Standard Safety Analysis Report configuration of the Westinghouse AP600 as of 1992

    The Health in All Policies (HiAP) approach requires formal and sustained governance structures and mechanisms to ensure that the policies of various non-health sectors maximize positive and minimize negative impacts on population health. In this paper, we demonstrate the usefulness of a network perspective in understanding and contributing to the effectiveness of HiAP. We undertook an exploratory, qualitative case study of a HiAP structure in Iran, the Kerman province Council of Health and Food Security (CHFS) with diverse members from health and non-health sectors. We analyzed relevant policy texts and interviewed 32 policy actors involved in the CHFS. Data were analyzed using within-case analysis and constant comparative methodology. Our findings suggest that CHFS governance from a network perspective drew in practice on elements of two competing network governance modes: the network administrative organization (NAO) and the lead organization mode. Our results also show that a shift from a hierarchical and market-based mode of interaction to a network logic within CHFS has not yet taken place. In addition, CHFS suffers from large membership and an inability to address complex 'wicked problems', as well as low trust, legitimacy and goal consensus among its members. Drawing on other HiAP studies and commentaries, insights from organization network theory, and in-depth findings from our case study, we conclude that a NAO may be the most effective mode of governance for tackling complex social problems in HiAP structures. Since similar studies are limited, and our single case study may not be transferable across all contexts, we suggest that further research be undertaken to explore HiAP structures from a network perspective in different institutional and cultural settings. With increasing emphasis given to HiAP approaches in national and international health policy discourse, it is important that comparative knowledge about the effectiveness of HiAP governance

    The accuracy of radiological diagnosis of Apical Periodontitis (AP) is reported between examiners with differents levels of clinical experience using panoramic radiographs. 1032 teeth in 41 panoramic radiographs have been diagnosed. The evaluation of the x-rays and radiological diagnosis is performed by three independent dentists for AP to each tooth. The teeth have presented without radiological signs of AP in 96.6%. The number of teeth classified with an uncertain diagnosis of AP at the has been inversely proportional to the number of years of experience of the examiner. The examiner A has been used as a reference and compared the diagnoses of other examiners.The percentage agreement for all teeth was 95% for examiner B and 94% for examiner C. Kappa for all has been of 0.44 for examiner B and 0.43 for examiner C. The different categories were analyzed separately, the inferior teeth and the anterior teeth have obtained the best results. The level of clinical experience of the examiner has been indifferent in the diagnosis of AP in panoramic radiographs; however, it is important experience in the number of radiographs extras that will be needed to give a radiological diagnosis definitive. The panoramic radiographs were reliable diagnostic tools for AP.

    As a new nuclear type, AP1000 will become the development direction of Chinese nuclear project. EPC General Contract mode is favored by nuclear owners both at home and abroad. Therefore, there is necessity for studying HSE management system and method suitable for AP1000 nuclear plant construction (ANPC) based on combination of AP1000 construction characters in EPC mode. This can not only ensure safety for ANPC but also positively promote national nuclear power development. For this reason, based on site HSE management of the first AP1000 nuclear plant under construction, HSE management system and method for ANPC in EPC mode was proposed after analysis of the character of EPC mode and ANPC character. It is hoped that it will be helpful for safe construction for ANPC. (authors)

    This paper reports that since 1987, Westinghouse has been performing containment cooling analyses in support of the Advanced AP600 plant design. This program was intended to verify the feasibility of the passive containment cooling system features of the AP600 design. To support this design, containment analyses of the AP600 containment for a large break LOCA and a large Steam Line Break were performed. The transient results indicate the feasibility of the passive containment design by demonstrating the capability to remove sufficient heat to limit containment atmosphere conditions to within acceptable limits following these postulated accidents. These results also indicate that the PCCS can reduce containment pressure to less than one-quarter design pressure at 24 hours following the most severe accident scenario thereby minimizing containment leakage concerns

    In this paper, 426 well known confirmed Ap and Am stars are photometrically studied in the infrared. The 2MASS, Wide-field Infrared Survey Explorer ( WISE ), and IRAS data are employed to make analyses. The results in this paper have shown that in the 1–3 μ m region over 90% Ap and Am stars have no or little infrared excesses, and infrared radiations in the near-infrared from these stars are probably dominated by the free–free emissions. It is also shown that in the 3–12 μ m region, the majority of Ap stars and Am stars have very similar behavior, i.e., in the W 1– W 2 (3.4–4.6 μ m) region, over half of Ap and Am stars have clear infrared excesses, which are possibly due to the binarity, the multiplicity, and/or the debris disk, but in the W 2– W 3 (4.6–12 μ m) region they have no or little infrared excess. In addition, in the 12–22 μ m region, some of Ap stars and Am stars show the infrared excesses and infrared radiations for these Ap and Am stars are probably due to the free–free emissions. In addition, it is seen that the probability of being the binarity, the multiplicity and/or the debris disk for Am stars is much higher than that for Ap stars. Furthermore, it can be seen that, in general, no relations can be found between infrared colors and spectral types either for Ap stars or for Am stars.

Todas las gestantes que asistieron, aceptaron recibir asesoramiento genético y se hizo el seguimiento de los casos. El 47,6 % concluyó el estudio del cónyuge en tiempo útil para optar por diagnóstico prenatal. Los resultados muestran la necesidad de reducir la edad gestacional en que se determina el riesgo de la pareja. Ello sería posible mediante el pesquisaje en la primera consulta prenatal, métodos más eficientes en comunicar con las gestantes positivas, y más agilidad en la realización de los análisis y en informar los resultados.Some aspects of the Cuban Programme for Prevention of Sickle Cell Anemia were analyze in Havana City during 1992. All pregnants detected with abnormal hemoglobins received an appointment by telegram to get an explanation about the significance of findings; 62,2 % attended promptly to the appointment; 21,6 % came later, making necessary the use of other mechanisms of communication with pregnants; and 16,2 % never attended. All pregnants who went to the appointment accepted genetic counseling and were followed up. Only 47,6 % concluded testing of partner early enough for consideration of prenatal diagnosis. The results showed the need to reduce gestational age in order to determine the risk of the couple. This is possible by screaning pregnants at the first prenatal visit, by using more efficient methods for contacting with positive women, and by doing the test and informing the results faster.

    Identifying reperfusion and predicting post procedure risk is important following Percutaneous Coronary Interventions (PCI). An Angiographic Perfusion Score (APS) combining TIMI flow (TFG) and myocardial perfusion (TMPG) grades before and after PCI can accurately measure both epicardial and myocardial perfusion and predict Major Adverse Cardiac Events (MACE). APS was calculated in 226 (88 ST elevation Myocardial Infarction (STEMI) and 138 Non STEMI) patients. Maximum score being 12, reperfusion was defined as failed: 0-3, partial: 4-9, and full APS: 10-12. Thirty day MACE were observed. APS identified reperfusion significantly more than TMPG alone (STEMI: 50.6% vs 11.8% (p APS group (1.8% vs 22.5%) (p APS detects more low risk reperfused patients, post PCI. Copyright © 2012.

    A technique of composite processing of Fe{sub 2}O{sub 3} and ammonium perchlorate (AP) was employed in making the propellant. The effects of composite processing of Fe{sub 2}O{sub 3} on catalytic activity, on the thermal decomposition of AP, and on the burning rate of the composite propellant were investigated in this paper. Fe{sub 2}O{sub 3}/AP composite particles were prepared by a novel solvent-nonsolvent method. The results show that AP is successfully coated on the surface of Fe{sub 2}O{sub 3}. Composite processing of Fe{sub 2}O{sub 3} and AP can improve the catalytic activity of Fe{sub 2}O{sub 3}. Fe{sub 2}O{sub 3} exhibits better catalytic effect with increasing Fe{sub 2}O{sub 3} content. The larger interface between Fe{sub 2}O{sub 3} and AP and lower density of composite propellant (with the added Fe{sub 2}O{sub 3}/AP composite particles) are responsible for the enhancement of the catalytic activity of Fe{sub 2}O{sub 3}.

    The Advanced Photon Source is in the process of developing an upgrade (APS-U) of the storage ring. The upgrade will be converting the current double bend achromat (DBA) lattice to a multi-bend achromat (MBA) lattice. In addition, the storage ring will be operated at 6 GeV and 200 mA with regular swap-out injection to keep the stored beam current constant [1]. The swap-out injection will take place with beamline shutters open. For radiation safety to ensure that no electrons can exit the storage ring, a passive method of protecting the beamline and containing the electrons inside the storage ring is proposed. A clearing magnet will be located in all beamline front ends inside the storage ring tunnel. This article will discuss the features and design of the clearing magnet scheme for APS-U.

    Trapped ions in the APS Particle Accumulator Ring (PAR) lead to a positive coherent tune shift in both planes, which increases along the PAR cycle as more ions accumulate. This effect has been studied using an ion simulation code developed at SLAC. After modifying the code to include a realistic vacuum profile, multiple ionization, and the effect of shaking the beam to measure the tune, the simulation agrees well with our measurements. This code has also been used to evaluate the possibility of ion instabilities at the high bunch charge needed for the APS-Upgrade.

    Full Text Available The shield building of AP1000 was designed to protect the steel containment vessel of the nuclear reactor. Therefore, the safety and integrity must be ensured during the plant life in any conditions such as an earthquake. The aim of this paper is to study the effect of water in the water tank on the response of the AP1000 shield building when subjected to three-dimensional seismic ground acceleration. The smoothed particle hydrodynamics method (SPH and finite element method (FEM coupling method is used to numerically simulate the fluid and structure interaction (FSI between water in the water tank and the AP1000 shield building. Then the grid convergence of FEM and SPH for the AP1000 shield building is analyzed. Next the modal analysis of the AP1000 shield building with various water levels (WLs in the water tank is taken. Meanwhile, the pressure due to sloshing and oscillation of the water in the gravity drain water tank is studied. The influences of the height of water in the water tank on the time history of acceleration of the AP1000 shield building are discussed, as well as the distributions of amplification, acceleration, displacement, and stresses of the AP1000 shield building. Research on the relationship between the WLs in the water tank and the response spectrums of the structure are also taken. The results show that the high WL in the water tank can limit the vibration of the AP1000 shield building and can more efficiently dissipate the kinetic energy of the AP1000 shield building by fluid-structure interaction.

    Systemic lupus erythematosus (SLE) and antiphospholipid antibody syndrome (APS) are autoimmune diseases that affect women of childbearing age. Pregnancies in these patients carry several complications such as prematurity. Maternal IgG antiphospholipid antibodies (aPL) can cross the placenta but they don't generally cause any neonatal thrombotic event. Because of the incompleteness of the fetal blood-brain barrier, aPL could theoretically reach the fetal brain. Whether this can have an effect on brain development is still under investigation. Some studies performed in children of patients with SLE and/or APS showed an increased number of learning disabilities without impairment in intelligence level. The objectives of this article are to evaluate the neurodevelopment outcome in 30 children (median age 9 years) born to mothers with SLE and/or APS with IgG anti-beta2-glycoprotein I during the third trimester of pregnancy and found positive for the same antibodies at birth. A neurological physical exam was performed in all children. We submitted some questionnaires to the mothers: the Child Behavior CheckList (CBCL) and a homemade set of questions obtained by a team composed of rheumatologists and pediatric neurologists. Intellectual functioning was determined by the Wechsler scale for corrected age. In all children neurological physical exam and intelligence levels were found to be normal but mild behavior disorders and history of neurological manifestations were shown in three children. Offspring of patients with SLE and/or APS are generally healthy. We and others observed the occurrence of minor neurological disorders that might be related to maternal disease or to prematurity. The limited number of the available data on this sensitive issue supports the need for further studies. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    A postulated double-ended guillotine break of a direct-vessel-injection line in an AP600 plant has been analyzed. This event is characterized as an intermediate break loss-of-coolant accident (IBLOCA). Most of the insights regarding the response of the AP600 safety systems to the postulated accident are derived from calculations performed with the TRAC-PFl/MOD2 code. However, complementary insights derived from a scaled experiment conducted in the ROSA facility, as well as insights based upon calculations by other codes, are also presented. The key processes occurring in an AP600 during a IBLOCA are primary coolant system depressurization, inventory depletion, inventory replacement via emergency core coolant injection, continuous core cooling, and long-term decay heat rejection to the atmosphere. Based upon the calculated and experimental results, the AP600 will not experience a core heat up and will reach a safe shutdown state using only safety-class equipment. Only the early part of the long-term cooling period initiated by In-containment Refueling Water Storage Tank injection was evaluated Thus, the observation that the core is continuously cooled should be verified for the latter phase of the long-term cooling period, the interval when sump injection and containment cooling processes are important

    To describe the prevalence of non-conventional APL in patients with obstetrical APS without conventional APL and the impact of treatment on pregnancy outcome. Patients with clinical obstetrical criteria were tested for anti-phosphatidylethanolamine (aPE) IgG/M, anti-prothrombin/phosphatidylserine (anti-PS/PT) IgG/M, and anti-annexin V IgG. Pregnancy losses rates were compared between APS, non-conventional APS, and non-APL and in untreated pregnancies to treated ones for each group. Using the cutoffs (ROC), 65/96 (68%) patients have been considered as non-conventional APS and compared to 83 APS and 31 patients without APL. The obstetrical history in non-conventional APS did not differ in comparison to confirmed APS. The frequencies of anti-annexin V IgG antibodies tended to be more frequent in non-conventional APS (88% versus 73%; p = 0.06), and those of anti-PE IgG and M were similar. The anti-PS/PT IgG and M antibodies were more frequent in confirmed APS than in non-conventional APS (63% and 37% versus 4% and 5%, respectively, p APS were compared with 81 pregnancies of confirmed APS and 132 pregnancies from non-APL group. Out of 474, 136 (29%) patients have been treated during pregnancies, and treatment significantly increased the rate of live birth (26% in untreated versus 72% in treated pregnancies, p APS and non-conventional APS, with odds ratio at 3.3 (95% CI: 1.8-6.1) and 6.9 (95% CI: 3.9-12.3) (p = 0.49) and significantly more important for the 2 APS groups pooled versus non-APL group [OR at 1.9 (95% CI: 1.1-3.5) for non-APL group versus 5.3 (95% CI: 3.5-8.1) for APS groups, p = 0.0025]. In this study, 68% of patients with clinical criteria for obstetrical APS seronegative for conventional APL have non-conventional APL. These patients have a significant decrement of pregnancy losses if they receive treatment for APS during their pregnancy. Copyright © 2016 Elsevier Inc. All rights reserved.

    Argonne National Laboratory is currently positioned to provide access to high performance regional and national networks. Much of the impetus for this effort is the anticipated needs of the upcoming experimental program at the APS. Some APS collaborative access teams (CATs) are already pressing for network speed improvements and security enhancements. Requirements range from the need for high data rate, secure transmission of experimental data, to the desire to establish a open-quote open-quote virtual experimental environment close-quote close-quote at their home institution. In the near future, 155 megabit/sec (Mb/s) national and regional asynchronous transfer mode (ATM) networks will be operational and available to APS users. Full-video teleconferencing, virtual presence operation of experiments, and high speed, secure transmission of data are being tested and, in some cases, will be operational. We expect these efforts to enable a substantial improvement in the speed of processing experimental results as well as an increase in convenience to the APS experimentalist. copyright 1996 American Institute of Physics

    Full Text Available Gomphotheriidae fossil remains from shore level of Santa Clara del Mar (Mar del Plata, Argentina are described. The comparative morphological and multivariate analysis of the m3 with other South American gomphotheres remains, mainly from Argentina, Bolivia and Brazil, allow their identification as Stegomastodon platensis. This species seems better adapted to live on the middle latitudes and warm climatic conditions. The possible movement routes from north to the most austral zones or areas are discussed. Stegomastodon from South America is a big-size form which is present along the East route and in several shore areas of Ecuador and Peru. In the present work some palaeoecological and palaeogeographical considerations are included. From a radiometric AMS datum, the remains of Santa Clara del Mar are dated in the late Pleistocene (17,880 ± 60 AP.Se describen restos bien conservados de gonfoterios (Mammalia, Proboscidea encontrados en los niveles pleistocenos que afloran en los acantilados costeros de Santa Clara del Mar (Mar del Plata, Argentina. Se analizan algunos de sus caracteres más importantes y se compara con otros gonfoterios provenientes de distintas localidades de Argentina, Brasil y Bolivia. El estudio comparativo, mediante análisis multivariante del m3, permitió su identificación como Stegomastodon platensis. Nosotros consideramos que todos los Gomphotheriidae del territorio actual de Argentina deberían incluirse en un único género y una única especie: Stegomastodon platensis. Esta especie parece estar mejor adaptada a vivir en latitudes medias, y en condiciones climáticas templadas. Se discuten sus posibles vías de desplazamiento desde el norte hacia zonas o áreas más australes. Stegomastodon de América del Sur es una forma de gran tamaño, que se encuentra a lo largo de la ruta del este y en algunas áreas costeras de Ecuador y Perú. En el presente artículo se incluyen algunas consideraciones paleoecológicas y

  1. Synthesis and binding properties of new selective ligands for the nucleobase opposite the AP site.

    DNA is continuously damaged by endogenous and exogenous factors such as oxidative stress or DNA alkylating agents. These damaged nucleobases are removed by DNA N-glycosylase and form apurinic/apyrimidinic sites (AP sites) as intermediates in the base excision repair (BER) pathway. AP sites are also representative DNA damages formed by spontaneous hydrolysis. The AP sites block DNA polymerase and a mismatch nucleobase is inserted opposite the AP sites by polymerization to cause acute toxicities and mutations. Thus, AP site specific compounds have attracted much attention for therapeutic and diagnostic purposes. In this study, we have developed nucleobase-polyamine conjugates as the AP site binding ligand by expecting that the nucleobase part would play a role in the specific recognition of the nucleobase opposite the AP site by the Watson-Crick base pair formation and that the polyamine part should contribute to the access of the ligand to the AP site by a non-specific interaction to the DNA phosphate backbone. The nucleobase conjugated with 3,3'-diaminodipropylamine (A-ligand, G-ligand, C-ligand, T-ligand and U-ligand) showed a specific stabilization of the duplex containing the AP site depending on the complementary combination with the nucleobase opposite the AP site; that is A-ligand to T, G-ligand to C, C-ligand to G, T- and U-ligand to A. The thermodynamic binding parameters clearly indicated that the specific stabilization is due to specific binding of the ligands to the complementary AP site. These results have suggested that the complementary base pairs of the Watson-Crick type are formed at the AP site. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Soft X-ray appearance potential spectroscopy (APS) and X-ray photoelectron spectroscopy (XPS) have been used to study vanadium, vanadium carbide, and graphite. The chemical shifts for vanadium carbide with respect to metallic vanadium and graphite are compared for the two methods. The Csub(K) structure in APS and the valence band in XPS for vanadium carbide show good agreement with the band structure calculations of Neckel and co-workers. Using the band structure calculations of Painter et al. it is also shown how the multi-peak structure in the APS spectrum of graphite is possibly due to density of states effects. It would therefore appear that plasmon coupling plays only a minor role.

    2017-03-25

    The Advanced Photon Source (APS) is currently in the preliminary design phase for the multi-bend achromat (MBA) lattice upgrade. Beam stability is critical for the MBA and will require long term drift defined as beam mo-tion over a seven-day timescale to be no more than 1 mi-cron at the insertion device locations and beam angle change no more than 0.25 micro-radian. Mechanical stabil-ity of beam position monitor (BPM) pickup electrodes mounted on insertion device vacuum chambers place a fun-damental limitation on long-term beam stability for inser-tion device beamlines. We present the design and imple-mentation of prototype mechanical motion system (MMS) instrumentation for quantifying this type of motion specif-ically in the APS accelerator tunnel and experiment hall floor under normal operating conditions. The MMS pres-ently provides critical position information on the vacuum chamber and BPM support systems. Initial results of the R&D prototype systems have demonstrated that the cham-ber movements far exceed the long-term drift tolerance specified for the APS Upgrade MBA storage ring.

  4. Amphioxus and lamprey AP-2 genes: implications for neural crest evolution and migration patterns

    2002-01-01

    The neural crest is a uniquely vertebrate cell type present in the most basal vertebrates, but not in cephalochordates. We have studied differences in regulation of the neural crest marker AP-2 across two evolutionary transitions: invertebrate to vertebrate, and agnathan to gnathostome. Isolation and comparison of amphioxus, lamprey and axolotl AP-2 reveals its extensive expansion in the vertebrate dorsal neural tube and pharyngeal arches, implying co-option of AP-2 genes by neural crest cells early in vertebrate evolution. Expression in non-neural ectoderm is a conserved feature in amphioxus and vertebrates, suggesting an ancient role for AP-2 genes in this tissue. There is also common expression in subsets of ventrolateral neurons in the anterior neural tube, consistent with a primitive role in brain development. Comparison of AP-2 expression in axolotl and lamprey suggests an elaboration of cranial neural crest patterning in gnathostomes. However, migration of AP-2-expressing neural crest cells medial to the pharyngeal arch mesoderm appears to be a primitive feature retained in all vertebrates. Because AP-2 has essential roles in cranial neural crest differentiation and proliferation, the co-option of AP-2 by neural crest cells in the vertebrate lineage was a potentially crucial event in vertebrate evolution.

    The comparison and analysis for the safety classification, seismic category, code classification and QA classification between AP1000 and traditional PWR were presented. The safety could be guaranteed and the construction and manufacture costs could be cut down since all sorts of AP1000 classifications. It is suggested that the QA classification and the QA requirements correspond to the national conditions should be drafted in the process of AP1000 domestication. (authors)

    Trabajo presentado al Primer Congreso Interamericano de Radiología – Buenos Aires, octubre 1943.

    El autor, teniendo en cuenta la divergencia que existe hoy en las opiniones de los clínicos, los cirujanos y los mismos radiólogos sobre el valor del examen radiológico cuando se sospecha una apendicitis crónica o de repetición, estudia los distintos períodos por los cuales ha pasado la radiología apendicular, para concluir que tal divergencia de pareceres se explica por la evolución que ha sufrido la clínica en los últimos años y por la dificultad en que hoy nos encontramos para saber si el apéndice extirpado era en realidad el causante de las molestias que aquejaban al enfermo.

    Casi todos los individuos que llegan a la edad adulta han sufrido en el curso de la vida un ataque inflamatorio apendicular. Por este motivo se explica que la mayor parte de los apéndices extirpados, aun aquellos que clínicamente se consideran sanos en el momento de la intervención quirúrgica, presenten lesiones microscópicas de un estado inflamatorio.

    La única manera de saber si el apéndice era el causante de las molestias que aquejaban al enfermo radica en la desaparición de los síntomas clínicos después de la apendicectomía.

    No puede existir, en el estado actual de nuestros conocimientos, un síntoma que sea patonogmónico de las apendicitis crónicas o de repetición, pero el estudio radiológico completo de las vías digestivas es no sólo útil sino necesario para el diagnóstico, por tres razones:

    The APS storage ring (1104 meters) is divided into 40 sectors. Each sector has 38 magnet coils in five magnet bases. Every alternate sector has an additional quadrupole magnet for skew correction. AR the main dipole magnets, two in each sector are connected in series and fed from one power supply unit. A base is controlled by one power supply control unit (PSCU). Each PSCU is connected to the host computer via a local area network (LAN). This note discusses the hardware configuration of the typical power supply control system used by the APS magnets and the software commands supported by the PSCU

    Full Text Available Aunque los apósitos de cura en ambiente (CAH húmedo se han utilizado predominantemente en heridas crónicas, ello no es óbice para que su uso en heridas agudas permita solucionar algunos problemas, como el conseguir un ambiente óptimo que facilite la migración epitelial, así como una adecuada protección de las heridas y una correcta gestión del exudado. Es por ello que, dentro del marco del estudio AURIGA-04, nos planteamos la realización de un estudio prospectivo observacional,abierto y multicéntrico, de medidas repetidas en una cohorte de pacientes que presentan heridas agudas de diversa etiología en el que se incluyeron pacientes con heridas traumáticas, quirúrgicas o quemaduras tratados por profesionales de Atención Primaria, con el objetivo de generar evidencias acerca de la utilización de apósitos de CAH, en concreto, de la gama de apósitos hidrocelulares Allevyn®, en el tratamiento de heridas agudas. Se consideraron como criterios de exclusión heridas con signos clínicos de infección. Solo se incluyó una lesión por paciente. En el caso de los pacientes con heridas agudas, la muestra a estudio quedó compuesta por 61 pacientes con una edad media de 71,1 años; 36 casos corresponden a mujeres (60%. El estado general de salud de la muestra era bueno en un 49,1% de los casos y prácticamente la totalidad de los pacientes presentaba pluripatología. Un 10% de los pacientes consumía fármacos que podían interferir en la cicatrización y un 6% presentaba malnutrición. El 67,2% de las lesiones eran heridas traumáticas, el 24,6% quirúrgicas y un 8,2% quemaduras. Un 37% de las lesiones fueron clasificadas como superficiales y el 63% restante como profundas. Presentaban 64 días de evolución previa a su inclusión en el estudio y una superficie media de 23,34 cm². Los pacientes permanecieron en el estudio un promedio de 43,6 días, con una cadencia de cambios de apósito cada 2,7 días. Durante el estudio cicatrizaron

    2001-01-01

    Objective: To study 99 Tc m labelled di-adenosine tetraphosphate (Ap4A), a compound can bind on P 2 purine receptors on atherosclerotic lesions, for imaging experimental atherosclerotic plaques in New Zealand White (NZW) rabbits. Methods: Twenty male NZW rabbits were submitted immune-injury and fed with high cholesterol diet for more than 2 months. To label the 99 Tc m to Ap4A, stannous tartrate solution was used. 99 Tc m -Ap4A was purified on a Sephadex G-25 column and tested for radiochemistry purity on thin layer chromatography. A biodistribution study was carried out on KM mice. Thirty minutes after intravenous injection of 7.4 MBq 99 Tc m -Ap4A, 5 normal NZW rabbits and 5 NZW rabbits with atherosclerotic lesions were sacrificed; their abdominal aortas were removed and covered with X-ray films. Exposed for 24 h in refrigerator, the films were developed and fixed. In another 5 NZW rabbits with atherosclerotic lesions, blood samples, atherosclerotic plaques and normal aortic wall samples were removed. Lesion to blood (target/blood, T/B), lesion to normal (target/non-target, T/NT) radioactivity ratios were calculated. 74 MBq 99 Tc m -Ap4A was injected into marginal ear veins of 5 atherosclerotic and 5 normal NZW rabbits. Simultaneously in vivo images were recorded for more than 4 h. In another group, 30 min after 99 Tc m -Ap4A administration, the animals were sacrificed and their abdominal aortas were removed. The abdominal aortas were placed on the face of SPECT and images acquisition was performed. Results: The radiochemistry purity of 99 Tc m -Ap4A was 85% to 91%. Biodistribution study revealed the clearance of 99 Tc m -Ap4A from blood was rapid. Thirty min after 99 Tc m -Ap4A administration, T/B radio was 3.17 +- 1.27, T/NT ratio was 5.23 +- 1.87. On the radioautography film shadows of atherosclerotic plaques were clearly visible. The atherosclerotic plaques on the aorta samples also can be seen on ex vivo images.

    Antiphospholipid antibody syndrome (APS) is one of the most common acquired thrombophilic disorders resulting in arterial and venous thromboses. APS is a major cause for cerebrovascular accidents or stokes, myocardial infarction, venous thromboembolism and recurrent abortions/pregnancy losses especially in young patients. APS patients have an increased risk of atherosclerotic cardiovascular events. There are only two studies on lipid abnormalities in APS patients. None of them have studied the relationship between individual laboratory tests for APS and lipid profile abnormalities. Here we describe the significance of the relationship between various APS tests and lipid profile abnormalities in a subset of APS patients who presented with arterial thrombosis in a tertiary care hospital. The study was conducted at Government Medical College, which is a tertiary care referral hospital. All patients who presented to the medicine department with APS during a two-year period were studied. A patient was considered to be positive for anticardiolipin (aCL) antibody or anti-β2 glycoprotein (anti-β2G) if the titer was more than 15 IU/mL, and a high titer was considered to be more than 40 IU/mL for Immunoglobulin (lg) IgG and IgM isotypes. The fasting lipid profile was measured in all patients, and lipid profile abnormalities were defined with cutoffs of low-density lipoprotein (LDL) levels of >150 mg/dL, triglyceride (TG) levels of >150 mg/dL, and high-density lipoprotein (HDL) levels of APS, aCL IgG and IgM and anti-β2G IgG and IgM, were determined by statistical analysis. The study population included 77 APS patients, with 53% of patients between 20 and 40 years. The commonest abnormality in the lipid profile test was elevated TG levels of >150 mg/dL in 51.9% of the patients, followed by low HDL levels (150 mg/dL) in 40.2% of the patients. There was a statistically significant relationship between anti-β2G IgG levels and HDL and LDL levels, but not TG levels. Only LDL

    Amigo, M-C

    2014-10-01

    Heart valve disease (HVD) is the most common cardiac manifestation in the antiphospholipid syndrome (APS). Valve lesions should be described according to the established definition. HVD is progressive despite anticoagulant/antiplatelet treatments. Around 4-6% of patients with HVD in APS will require valve replacement surgery, which is considered a very high risk procedure in APS. Unfortunately, no recommendations regarding medical treatment of antiphospholipid antibodies-associated HVD can be made at this moment. There are evidence-based data and strong pathophysiologic rationale for considering HVD as a manifestation of APS. Thus, HVD should be included as a criterion of definite APS. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Andrographis paniculata is widely used as medicinal herb in China for a long time and andrographolide is its main medicinal constituent. To investigate the underlying andrographolide biosynthesis mechanisms, RNA-seq for A. paniculata leaves with MeJA treatment was performed. In A. paniculata transcriptomic data, the expression pattern of one member of NAC transcription factor family (ApNAC1) matched with andrographolide accumulation. The coding sequence of ApNAC1 was cloned by RT-PCR, and GenBank accession number was KY196416. The analysis of bioinformatics showed that the gene encodes a peptide of 323 amino acids, with a predicted relative molecular weight of 35.9 kDa and isoelectric point of 6.14. To confirm the subcellular localization, ApNAC1-GFP was transiently expressed in A. paniculata protoplast. The results indicated that ApNAC1 is a nucleus-localized protein. The analysis of real-time quantitative PCR revealed that ApNAC1 gene predominantly expresses in leaves. Compared with control sample, its expression abundance sharply increased with methyl jasmonate treatment. Based on its expression pattern, ApNAC1 gene might involve in andrographolide biosynthesis. ApNAC1 was heterologously expressed in Escherichia coli and recombinant protein was purified by Ni-NTA agarose. Further study will help us to understand the function of ApNAC1 in andrographolide biosynthesis. Copyright© by the Chinese Pharmaceutical Association.

    Extensive prototyping of storage ring magnets is ongoing at the Advanced Photon Source (APS) in support of the APS Multi-Bend Achromat (MBA) upgrade project (APS-U) [1]. As part of the R&D activities four quadrupole magnets with slightly different geometries and pole tip materials, and one sextupole magnet with vanadium permendur (VP) pole tips were designed, built and tested. Magnets were measured individually using a rotating coil and a Hall probe for detailed mapping of the magnetic field. Magnets were then assembled and aligned relative to each other on a steel support plate and concrete plinth using precision machined surfaces to gain experience with the alignment method chosen for the APS-U storage ring magnets. The required alignment of magnets on a common support structure is 30 μm rms. Measurements of magnetic field quality, strength and magnet alignment after subjecting the magnets and assemblies to different tests are presented.

    The performance requirements of the Advanced Photon Source (APS) challenge the control system in a number of areas. This paper will review a few applications of advanced technology in the control and monitoring of the APS. The application of digital signal processors (DSPs) and techniques will be discussed, both from the perspective of a large distributed multiprocessor system and from that of embedded systems. In particular, two embedded applications will be highlighted, a beam position monitor processor and a DSP-based power supply controller. Fast data distribution is often a requirement. The application of a high-speed network based on reflective memory will also be discussed in the context of the APS global orbit feedback system. Timing systems provide opportunities to apply technologies such as high-speed logic and fiber optics. Examples of the use of these technologies will also be included. Finally, every modern accelerator control system of any size requires networking. Features of the APS accelerator controls network will be discussed

    The AP1000{sup R} passive nuclear power plant is uniquely equipped to withstand an extended station blackout scenario such as the events following the earthquake and tsunami at Fukushima without compromising core and containment integrity. The AP1000 plant shuts down the reactor, cools the core, containment and spent fuel pool for more than 3 days using passive systems that do not require AC or DC power or operator actions. Following this passive coping period, minimal operator actions are needed to extend the operation of the passive features to 7 days using installed equipment. To provide defense-in-depth for design extension conditions, the AP1000 plant has engineered features that mitigate the effects of core damage. Engineered features retain damaged core debris within the reactor vessel as a key feature. Other aspects of the design protect containment integrity during severe accidents, including unique features of the AP1000 design relative to passive containment cooling with water and air, and hydrogen management.

    Headaches have been extensively reported in Antiphospholipid syndrome (APS)/Antiphospholipid antibodies (aPL)-positive patients. The aim of this study was to highlight the prevalence of headaches among APS/aPL-positive patients and discuss its association with laboratory, clinical and imaging findings. We searched the literature through Google Scholar and PubMed for publications on the epidemiology, pathogenesis, laboratory, imaging and clinical findings, and management of headaches in APS/aPL-positive patients. The following keywords were used: Antiphospholipid, Hughes syndrome, anticardiolipin, lupus anticoagulant, anti-β2 glycoprotein I, headache, migraine, tension, and cluster. All reports published between 1969 and 2015 were included. Migraine is the most commonly reported type of headache in APS/aPL-positive patients. Thrombotic and platelet dysfunction hypotheses have been studied to uncover the pathogenic role of aPL in the development of headaches. Several studies are reporting higher levels of aPL in primary and secondary APS migraineurs, but only few reached statistical significance. Migraine patients without clinical signs/symptoms of cerebral infarction rarely show positive imaging findings. Digital subtraction angiography shows promise in demonstrating small vascular lesions otherwise not detected on computed tomography, magnetic resonance imaging, or cerebral angiograms. Although it may be solitary and harmless in many cases, the deleterious effect of migraine on the quality of life of APS patients prompts rapid diagnosis and proper management. An anticoagulation trial is advisable in APS patients with migraine as many cases of severe, refractory migraine resolved with anticoagulation therapy. The profile of migraine headaches discussed in this study permits its candidacy for inclusion in future APS classification criteria.

    The present study investigated the roles of E6 and E6AP in the Wnt pathway. We showed that E6 levels are markedly reduced in cells in which Wnt signaling is activated. Coexpression of wild-type or mutant E6AP (C820A) in Wnt-activated cells stabilized E6 and enhanced Wnt/β-catenin/TCF transcription. Expression of E6AP alone in nonstimulated cells elevated β-catenin level, promoted its nuclear accumulation, and activated β-catenin/TCF transcription. A knockdown of E6AP lowered β-catenin levels. Coexpression with E6 intensified the activities of E6AP. Further experiments proved that E6AP/E6 stabilize β-catenin by protecting it from proteasomal degradation. This function was dependent on the catalytic activity of E6AP, the kinase activity of GSK3β and the susceptibility of β-catenin to GSK3β phosphorylation. Thus, this study identified E6AP as a novel regulator of the Wnt signaling pathway, capable of cooperating with E6 in stimulating or augmenting Wnt/β-catenin signaling, thereby possibly contributing to HPV carcinogenesis. - Highlights: • The roles of E6 and E6AP in the Wnt pathway were investigated. • E6AP stabilizes E6 and enhances E6 activity in augmentation of Wnt signaling. • E6AP cooperates with E6 to stabilize β-catenin and stimulate Wnt/β-catenin signaling. • E6AP and E6 act through different mechanisms to augment or stimulate Wnt signaling

    La última novela de Gabriel García Márquez ha puesto sobre el tapete la historia de la epidemia de cólera que asoló a nuestro país en los años de 1849 y 1850.

    Como se sabe, el cólera es una gravísima enfermedad que puede producir la muerte en pocas horas. Se caracteriza por diarrea y vómito que llevan a una pronta deshidratación. En su período álgido, que es patognomónica del mal, el paciente es presa de un frío extremo, como la palabra lo indica. La mortalidad puede alcanzar hasta a un cincuenta por ciento de las personas afectadas que son, principalmente, las de menores recursos económicos.

    En Cartagena, según los datos que en sus Memorias consigna don Salvador Camacho Roldán, quien fue contemporáneo de los sucesos, murió una cuarta parte de la población por esta causa: de sus diez mil habitantes de entonces, fallecieron dos mil cuatrocientos afectados por el cólera morbo (1.

    En esa época no se conocía el origen ni el modo de contagiarse el mal. Se aceptaba que, llevados “por las altas regiones de la atmósfera” los miasmas, transmitidos por los malos olores, eran su causa. El descubrimiento en 1884 por Roberto Koch del Vibrio cholera, la bacteria productora de la enfermedad, que se adquiere al tomar agua contaminada con las heces de quien padece el mal, permitió saber su patogenia, que John Snow había intuído en Londres al observar que el cólera era contraído por los usuarios de la bomba de agua de Broad Street, tal como lo publicó en 1854 en su estudio titulado “On the mode of Communication of Cholera “. (2.

    A mediados del siglo pasado el cólera morbo se extendió por el mundo en forma de una pandemia. Parece que de Bengala pasó a la India y atacó después a Europa y los Estados Unidos.

    A nuestro país vino en enero de 1849 por el puerto de Colón, en Panamá. Nos lo informa el doctor Domingo Arosemena, testigo de excepción, quien atendió el primer caso en la ciudad

  5. Overview of the advanced photon source (APS)

    The Advanced Photon Source (APS) is a state-of-the-art synchrotron light source facility dedicated to the production of extremely brilliant x-ray beams for research. Its super-intense x-ray beams will be used in many areas of research including industrial research, biological and medical research, defense-related research, and basic research. The APS x-ray beams will allow scientists to study smaller samples, more complex systems, faster reactions and processes, and gather data at a greater level of detail than has been possible to date. Creation of these beams begins with electron production by an electron gun with a thermionic cathode. The electrons are accelerated to 200 MeV by a linear accelerator (linac) and then impinge on a tungsten target, resulting in electron-positron pair production. The positrons are accelerated to 450 MeV in the remainder of the linac, then accumulated, damped, and transferred to a synchrotron that increases their energy to 7 GeV. The 7-GeV positrons are injected into a storage ring, where they pass through special magnets that cause them to emit x-rays of the desired quality. Construction at ANL is nearly complete at this time, and the APS will begin operating for users in 1996. The accelerator and experimental facilities are described in this paper, and a brief overview of some of the experimental programs is given

    When it was installed,the Advanced Photon Source (APS) control system network was at the state-of-the-art. Different aspects of the system have been reported at previous meetings [1,2]. As loads on the controls network have increased due to newer and faster workstations and front-end computers, we have found performance of the system declining and have implemented an upgraded network. There have been dramatic advances in networking hardware in the last several years. The upgraded APS controls network replaces the original FDDI backbone and shared Ethernet hubs with redundant gigabit uplinks and fully switched 10/100 Ethernet switches with backplane fabrics in excess of 20 Gbits/s (Gbps). The central collapsed backbone FDDI concentrator has been replaced with a Gigabit Ethernet switch with greater than 30 Gbps backplane fabric. Full redundancy of the system has been maintained. This paper will discuss this upgrade and include performance data and performance comparisons with the original network

    Full Text Available Abstract Background High-density genotyping arrays that measure hybridization of genomic DNA fragments to allele-specific oligonucleotide probes are widely used to genotype single nucleotide polymorphisms (SNPs in genetic studies, including human genome-wide association studies. Hybridization intensities are converted to genotype calls by clustering algorithms that assign each sample to a genotype class at each SNP. Data for SNP probes that do not conform to the expected pattern of clustering are often discarded, contributing to ascertainment bias and resulting in lost information - as much as 50% in a recent genome-wide association study in dogs. Results We identified atypical patterns of hybridization intensities that were highly reproducible and demonstrated that these patterns represent genetic variants that were not accounted for in the design of the array platform. We characterized variable intensity oligonucleotide (VINO probes that display such patterns and are found in all hybridization-based genotyping platforms, including those developed for human, dog, cattle, and mouse. When recognized and properly interpreted, VINOs recovered a substantial fraction of discarded probes and counteracted SNP ascertainment bias. We developed software (MouseDivGeno that identifies VINOs and improves the accuracy of genotype calling. MouseDivGeno produced highly concordant genotype calls when compared with other methods but it uniquely identified more than 786000 VINOs in 351 mouse samples. We used whole-genome sequence from 14 mouse strains to confirm the presence of novel variants explaining 28000 VINOs in those strains. We also identified VINOs in human HapMap 3 samples, many of which were specific to an African population. Incorporating VINOs in phylogenetic analyses substantially improved the accuracy of a Mus species tree and local haplotype assignment in laboratory mouse strains. Conclusion The problems of ascertainment bias and missing

  8. Expansion and Functional Divergence of AP2 Group Genes in Spermatophytes Determined by Molecular Evolution and Arabidopsis Mutant Analysis

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available The APETALA2 (AP2 genes represent the AP2 group within a large group of DNA-binding proteins called AP2/EREBP. The AP2 gene is functional and necessary for flower development, stem cell maintenance, and seed development, whereas the other members of AP2 group redundantly affect flowering time. Here we study the phylogeny of AP2 group genes in spermatophytes. Spermatophyte AP2 group genes can be classified into AP2 and TOE types, six clades, and we found that the AP2 group homologs in gymnosperms belong to the AP2 type, whereas TOE types are absent, which indicates the AP2 type gene are more ancient and TOE type was split out of AP2 type and losing the major function. In Brassicaceae, the expansion of AP2 and TOE type lead to the gene number of AP2 group were up to six. Purifying selection appears to have been the primary driving force of spermatophyte AP2 group evolution, although positive selection occurred in the AP2 clade. The transition from exon to intron of AtAP2 in Arabidopsis mutant leads to the loss of gene function and the same situation was found in AtTOE2. Combining this evolutionary analysis and published research, the results suggest that typical AP2 group genes may first appear in gymnosperms and diverged in angiosperms, following expansion of group members and functional differentiation. In angiosperms, AP2 genes (AP2 clade inherited key functions from ancestors and other genes of AP2 group lost most function but just remained flowering time controlling in gene formation. In this study, the phylogenies of AP2 group genes in spermatophytes was analyzed, which supported the evidence for the research of gene functional evolution of AP2 group.

  9. Energetics and dynamics of the non-natural fluorescent 4AP:DAP base pair

    The fluorescent non-natural 4-aminophthalimide (4AP) base, when paired to the complementary 2,4-diaminopyrimidine (DAP) nucleobase, is accommodated in a B-DNA duplex being efficiently recognized and incorporated by DNA polymerases. To complement the experimental studies and rationalize the impact of the above non-natural bases on the structure, stability and dynamics of nucleic acid structures, we performed quantum mechanics (QM) calculations along with classical molecular dynamics (MD) simulations. QM calculations were initially focused on the geometry and energetics of the 4AP:DAP non-natural pair and of H-bonded base pairs between 4AP and all the natural bases in their classical Watson-Crick geometries. The QM calculations indicate that the 4AP:DAP pair, despite the fact that it can form 3 H-bonds in a classic Watson-Crick geometry, has a stability comparable to the A:T pair. Then, we extended the study to reverse Watson-Crick geometries, characteristic of parallel strands. MD simulations were carried out on two 13-mer DNA duplexes, featuring a central 4AP:DAP or A:T pair, respectively. No major structural deformation of the duplex was observed during the MD simulation. Snapshots from the MD simulations were subjected to QM calculations to investigate the 4AP:DAP interaction energy when embedded into a duplex structure, and to investigate the impact of the two non-natural bases on the stacking interactions with adjacent bases in the DNA duplex. We found a slight increase in stacking interactions involving the 4AP:DAP pair, counterbalanced by a moderate decrease in H-bonding interactions of the 4AP:DAP and of the adjacent base pairs in the duplex. The results of our study are in agreement with experimental data and complement them by providing an insight into which factors contribute positively and which factors contribute negatively to the structural compatibility of the fluorescent 4AP:DAP pair with a B-DNA structure.

    This paper describes the development and psychometric evaluation of the Assistance to Participate Scale (APS). The APS measures the assistance that a school-aged child with a disability requires to participate in play and leisure activities from the primary carer's perspective. Mixed methodology using an instrument design model was used to complete two studies. First, a qualitative research design was used to generate items and scoring criteria for the APS. Second, a quantitative study evaluated the instrument using data collected from 152 mothers with children aged 5-18 years. Statistical analysis assessed the underlying structure, internal consistency and construct validity of the APS. Exploratory factor analysis revealed two correlated components, reflecting home-based and community-based play activities. Both subscales and the total APS scale showed good internal consistency. The APS correlated as predicted with individual domains and overall scores for other validated measures (Pediatric Evaluation of Disability Inventory caregiver scales and Pediatric Quality of Life Inventory) with correlations ranging from rho = 0.42 to rho = 0.77. The APS was able to discriminate between groups of children based on type of schooling (regular or segregated), need for equipment/assistive devices, frequency of lifting and disability. The APS provides professionals with a brief psychometrically sound tool that measures the amount of caregiver assistance provided to a child with a disability to participate in play and recreation. The APS may be used as an outcome measure and to evaluate and predict the amount and type of additional assistance families need to facilitate their child's participation in an important aspect of the child's daily life and development: play and recreation.

    Antiphospholipid syndrome (APS) is an autoimmune hypercoagulable disorder that has been shown to cause a large number of cardiac and neurological manifestations. Two recent studies have demonstrated abnormalities in cardiovascular autonomic function testing in APS patients without other cardiovascular or autoimmune disease. However, an association between autonomic disorders such as postural tachycardia syndrome and APS has not previously been described. Data were obtained by retrospective chart review. We identified 15 patients who have been diagnosed with APS and an autonomic disorder. The median age of the patients at the time of data analysis was 39 years. The autonomic disorders seen in these patients included postural tachycardia syndrome, neurocardiogenic syncope and orthostatic hypotension. The majority of patients (14/15) were female and the majority (14/15) had non-thrombotic neurological manifestations of APS, most commonly migraine, memory loss and balance disorder. Many also had livedo reticularis (11/15) and Raynaud's phenomenon (nine of 15). In some patients, the autonomic manifestations improved with anticoagulation and/or anti-platelet therapy; in others they did not. Two patients with postural tachycardia syndrome who failed to improve with the usual treatment of APS have been treated with intravenous immunoglobulin with significant improvement in their autonomic symptoms. We believe that autonomic disorders in APS may represent an important clinical association with significant implications for treatment. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available The pseudo-historicity, spurious attribution and alleged translation of a lost manuscript was a paratextual theme widely used in the Spanish literature of the Golden Age, usually associated with a taletype in which the author tells the circumstances of finding the lost text. Delpech focuses on the relations of such a theme —essential in apocrypha and in the literature of Revelation— to the mythology underlying talismanic magic. He argues that this mythology is rooted in some esoteric trends of Judaism and Islam that originated in the Hermetic Tradition, where ancient views of the East on the heavenly origin of writing and the holy nature of the book converged.El tópico paratextual de la seudo-historicidad, de la atribución imaginaria y de la fingida traducción de un manuscrito perdido tuvo amplia difusión en la narrativa aurisecular. Suele asociarse a un cuento-tipo más o menos embrionario en el que se relatan las circunstancias del hallazgo del escrito oculto. En este artículo se estudian las relaciones de dicho estereotipo —también fundamental en las producciones apócrifas y en la literatura de Revelación— con la mitología subyacente en la magia talismánica. Se trata de poner en evidencia el arraigo de esta mitología en las tradiciones esotéricas judías y musulmanas tributarias de la corriente hermética, en la que confluyeron antiguas representaciones orientales relativas a la procedencia transcendente de la escritura y al carácter sagrado del Libro.

  18. Role of the AP-5 adaptor protein complex in late endosome-to-Golgi retrieval.

    Directory of Open Access Journals (Sweden)

    Jennifer Hirst

    2018-01-01

    Full Text Available The AP-5 adaptor protein complex is presumed to function in membrane traffic, but so far nothing is known about its pathway or its cargo. We have used CRISPR-Cas9 to knock out the AP-5 ζ subunit gene, AP5Z1, in HeLa cells, and then analysed the phenotype by subcellular fractionation profiling and quantitative mass spectrometry. The retromer complex had an altered steady-state distribution in the knockout cells, and several Golgi proteins, including GOLIM4 and GOLM1, were depleted from vesicle-enriched fractions. Immunolocalisation showed that loss of AP-5 led to impaired retrieval of the cation-independent mannose 6-phosphate receptor (CIMPR, GOLIM4, and GOLM1 from endosomes back to the Golgi region. Knocking down the retromer complex exacerbated this phenotype. Both the CIMPR and sortilin interacted with the AP-5-associated protein SPG15 in pull-down assays, and we propose that sortilin may act as a link between Golgi proteins and the AP-5/SPG11/SPG15 complex. Together, our findings suggest that AP-5 functions in a novel sorting step out of late endosomes, acting as a backup pathway for retromer. This provides a mechanistic explanation for why mutations in AP-5/SPG11/SPG15 cause cells to accumulate aberrant endolysosomes, and highlights the role of endosome/lysosome dysfunction in the pathology of hereditary spastic paraplegia and other neurodegenerative disorders.

    The activator protein-1 (AP-1) transcription factor is believed to be important in tumorigenesis and altered AP-1 activity was associated with cell transformation. We aimed to assess the potential role of AP-1 family members as novel biomarkers in breast cancer. We studied the expression of AP-1 members at the mRNA level in 72 primary breast tumors and 37 adjacent non-tumor tissues and evaluated its correlation with clinicopathological parameters including estrogen receptor (ER), progesterone receptor (PR) and HER2/neu status. Expression levels of Ubiquitin C (UBC) were used for normalization. Protein expression of AP-1 members was assessed using Western blot analysis in a subset of tumors. We used student’s t-test, one-way ANOVA, logistic regression and Pearson’s correlation coefficient for statistical analyses. We found significant differences in the expression of AP-1 family members between tumor and adjacent non-tumor tissues for all AP-1 family members except Fos B. Fra-1, Fra-2, Jun-B and Jun-D mRNA levels were significantly higher in tumors compared to adjacent non-tumor tissues (p < 0.001), whilst c-Fos and c-Jun mRNA levels were significantly lower in tumors compared with adjacent non-tumor tissues (p < 0.001). In addition, Jun-B overexpression had outstanding discrimination ability to differentiate tumor tissues from adjacent non-tumor tissues as determined by ROC curve analysis. Moreover, Fra-1 was significantly overexpressed in the tumors biochemically classified as ERα negative (p = 0.012) and PR negative (p = 0.037). Interestingly, Fra-1 expression was significantly higher in triple-negative tumors compared with luminal carcinomas (p = 0.01). Expression levels of Fra-1 and Jun-B might be possible biomarkers for prognosis of breast cancer

    We compare a new CMOS Active Pixel Sensor (APS) to a Princeton Instruments PIXIS-XO: 2048B Charge Coupled Device (CCD) with soft X-rays tested in a synchrotron beam line at the Diamond Light Source (DLS). Despite CCDs being established in the field of scientific imaging, APS are an innovative technology that offers advantages over CCDs. These include faster readout, higher operational temperature, in-pixel electronics for advanced image processing and reduced manufacturing cost. The APS employed was the Vanilla sensor designed by the MI3 collaboration and funded by an RCUK Basic technology grant. This sensor has 520 x 520 square pixels, of size 25 μm on each side. The sensor can operate at a full frame readout of up to 20 Hz. The sensor had been back-thinned, to the epitaxial layer. This was the first time that a back-thinned APS had been demonstrated at a beam line at DLS. In the synchrotron experiment soft X-rays with an energy of approximately 708 eV were used to produce a diffraction pattern from a permalloy sample. The pattern was imaged at a range of integration times with both sensors. The CCD had to be operated at a temperature of -55°C whereas the Vanilla was operated over a temperature range from 20°C to -10°C. We show that the APS detector can operate with frame rates up to two hundred times faster than the CCD, without excessive degradation of image quality. The signal to noise of the APS is shown to be the same as that of the CCD at identical integration times and the response is shown to be linear, with no charge blooming effects. The experiment has allowed a direct comparison of back thinned APS and CCDs in a real soft x-ray synchrotron experiment.

  2. Synaptic and genomic responses to JNK and AP-1 signaling in Drosophila neurons

    2005-06-01

    Full Text Available Abstract Background The transcription factor AP-1 positively controls synaptic plasticity at the Drosophila neuromuscular junction. Although in motor neurons, JNK has been shown to activate AP-1, a positive regulator of growth and strength at the larval NMJ, the consequences of JNK activation are poorly studied. In addition, the downstream transcriptional targets of JNK and AP-1 signaling in the Drosophila nervous system have yet to be identified. Here, we further investigated the role of JNK signaling at this model synapse employing an activated form of JNK-kinase; and using Serial Analysis of Gene Expression and oligonucleotide microarrays, searched for candidate early targets of JNK or AP-1 dependent transcription in neurons. Results Temporally-controlled JNK induction in postembryonic motor neurons triggers synaptic growth at the NMJ indicating a role in developmental plasticity rather than synaptogenesis. An unexpected observation that JNK activation also causes a reduction in transmitter release is inconsistent with JNK functioning solely through AP-1 and suggests an additional, yet-unidentified pathway for JNK signaling in motor neurons. SAGE profiling of mRNA expression helps define the neural transcriptome in Drosophila. Though many putative AP-1 and JNK target genes arose from the genomic screens, few were confirmed in subsequent validation experiments. One potentially important neuronal AP-1 target discovered, CG6044, was previously implicated in olfactory associative memory. In addition, 5 mRNAs regulated by RU486, a steroid used to trigger conditional gene expression were identified. Conclusion This study demonstrates a novel role for JNK signaling at the larval neuromuscular junction and provides a quantitative profile of gene transcription in Drosophila neurons. While identifying potential JNK/AP-1 targets it reveals the limitations of genome-wide analyses using complex tissues like the whole brain.

    AP2/ERF transcription factors play a critical role in plant development and stress adaptation. This study reports the three-dimensional ab initio-based model of AP2/EREBP protein of barley and its interaction with DNA. Full-length coding sequence of HvAP2/EREBP gene isolated from two Indian barley cultivars, RD 2503 and RD 31, was used to model the protein. Of five protein models obtained, the one with lowest C-score was chosen for further analysis. The N- and C-terminal regions of HvAP2 protein were found to be highly disordered. The dynamic properties of AP2/EREBP and its interaction with DNA were investigated by molecular dynamics simulation. Analysis of trajectories from simulation yielded the equilibrated conformation between 2-10ns for protein and 7-15ns for protein-DNA complex. We established relationship between DNA having GCC box and DNA-binding domain of HvAP2/EREBP was established by modeling 11-base-pair-long nucleotide sequence and HvAP2/EREBP protein using ab initio method. Analysis of protein-DNA interaction showed that a β-sheet motif constituting amino acid residues THR105, ARG100, ARG93, and ARG83 seems to play important role in stabilizing the complex as they form strong hydrogen bond interactions with the DNA motif. Taken together, this study provides first-hand comprehensive information detailing structural conformation and interactions of HvAP2/EREBP proteins in barley. The study intensifies the role of computational approaches for preliminary examination of unknown proteins in the absence of experimental information. It also provides molecular insight into protein-DNA binding for understanding and enhancing abiotic stress resistance for improving the water use efficiency in crop plants.

    Full Text Available The high bandwidth demand of Internet applications has recently driven the need of increasing the residential download speed. A practical solution to the problem is to aggregate the bandwidth of 802.11 access points (APs backhauls in range. Since 802.11 devices are usually single radio, the communication to APs on different radio channels requires a time-division multiple access (TDMA policy at the client station. With an in-depth experimental analysis and a customized 802.11 driver, in this paper, we show that the usage of multi-AP TDMA policy may cause degradation of the TCP throughput and an underutilization of the AP backhauls. We then introduce a simple analytical model that accurately predicts the TCP round-trip time (RTT with a multi-AP TDMA policy and propose a resource allocation algorithm to reduce the observed TCP RTT with a very low computational cost. Our proposed scheme runs locally at the client station and improves the aggregate throughput up to 1.5 times compared to state-of-the-art allocations. We finally show that the throughput achieved by our algorithm is very close to the theoretical upper bound in key simulation scenarios.

    Highlights: • The PSO algorithm is applied for control parameter optimization of AP1000 reactor. • Key parameters of the MSHIM control system are optimized. • Optimization results are evaluated though simulations and quantitative analysis. - Abstract: The advanced mechanical shim (MSHIM) core control strategy is implemented in the AP1000 reactor for core reactivity and axial power distribution control simultaneously. The MSHIM core control system can provide superior reactor control capabilities via automatic rod control only. This enables the AP1000 to perform power change operations automatically without the soluble boron concentration adjustments. In this paper, the Particle Swarm Optimization (PSO) algorithm has been applied for the parameter optimization of the MSHIM control system to acquire better reactor control performance for AP1000. System requirements such as power control performance, control bank movement and AO control constraints are reflected in the objective function. Dynamic simulations are performed based on an AP1000 reactor simulation platform in each iteration of the optimization process to calculate the fitness values of particles in the swarm. The simulation platform is developed in Matlab/Simulink environment with implementation of a nodal core model and the MSHIM control strategy. Based on the simulation platform, the typical 10% step load decrease transient from 100% to 90% full power is simulated and the objective function used for control parameter tuning is directly incorporated in the simulation results. With successful implementation of the PSO algorithm in the control parameter optimization of AP1000 reactor, four key parameters of the MSHIM control system are optimized. It has been demonstrated by the calculation results that the optimized MSHIM control system parameters can improve the reactor power control capability and reduce the control rod movement without compromising AO control. Therefore, the PSO based optimization

  15. AfAP2-1, An Age-Dependent Gene of Aechmea fasciata, Responds to Exogenous Ethylene Treatment

    Directory of Open Access Journals (Sweden)

    Ming Lei

    2016-02-01

    Full Text Available The Bromeliaceae family is one of the most morphologically diverse families with a pantropical distribution. To schedule an appropriate flowering time for bromeliads, ethylene is commonly used to initiate flower development in adult plants. However, the mechanism by which ethylene induces flowering in adult bromeliads remains unknown. Here, we identified an APETALA2 (AP2-like gene, AfAP2-1, in Aechmea fasciata. AfAP2-1 contains two AP2 domains and is a nuclear-localized protein. It functions as a transcriptional activator, and the activation domain is located in the C-terminal region. The expression level of AfAP2-1 is higher in juvenile plants than in adult plants, and the AfAP2-1 transcript level was rapidly and transiently reduced in plants treated with exogenous ethylene. Overexpression of AfAP2-1 in Arabidopsis thaliana results in an extremely delayed flowering phenotype. These results suggested that AfAP2-1 responds to ethylene and is a putative age-dependent flowering regulator in A. fasciata.

    Marfan syndrome is characterized by high expression of matrix metalloproteinases (MMPs) in aortic smooth muscle cells (AoSMCs) associated with medial elastolysis and aortic root aneurysm. We aimed to reduce aortic elastolysis through decrease of MMP expression with decoy oligodeoxynucleotides (dODNs) neutralizing the transcription factor activating factor-1 (AP-1). AP-1 abundance in nuclear extracts as well as MMP-2 and MMP-9 expression were significantly increased in isolated mAoSMC of mgR/mgR Marfan mice compared to wild-type cells. Exposure to AP-1 neutralizing dODNs resulted in a significant reduction of basal and interleukin-1β-stimulated MMP expression and activity in mAoSMCs. Moreover, increased migration and formation of superoxide radical anions was substantially decreased in mAoSMCs by AP-1 dODN treatment. Aortic grafts from donor Marfan mice were treated with AP-1- dODN ex vivo and implanted as infrarenal aortic interposition grafts in mgR/mgR mice. Pretreatment of aortic grafts with AP-1 dODN led to reduced elastolysis, macrophage infiltration, and MMP activity. Permeability of the endothelial monolayer was increased for dODN in mgR/mgR aortae with observed loss of tight junction proteins ZO-1 and occludin, enabling dODN to reach the tunica media. Targeting AP-1 activity offers a new potential strategy to treat the vascular phenotype associated with Marfan syndrome. Copyright © 2017 The Author(s). Published by Elsevier Inc.

    The AP1000 plant is an 1100-M We pressurized water reactor with passive safety features and extensive plant simplifications and standardization that simplify construction, operation, maintenance, safety, and cost. The AP1000 plant is based on proven pressurized water reactor (PWR) technology, with an emphasis on safety features that rely solely on natural forces. These passive safety features are combined with simple, active, defense-in-depth systems used during normal plant operations which also provide the first level of defense against more probable events. This paper focuses on specific safety and licensing topics: the AP1000 plant robustness to be prepared for extreme events that may lead to catastrophic loss of infrastructure, such as the Fukushima Dai-ichi event, and the AP1000 plant compliance with the safety objectives for new plants. The first deployment of the AP1000 plant formally began in July 2007 when Westinghouse Electric Company and its consortium partner, the Shaw Group, signed contracts for four AP1000 units on coastal sites of Sanmen and Haiyang, China. Both sites have the planned ability to accommodate at least six AP1000 units; construction is largely concurrent for all four units. Additionally, the United States (U.S.) Nuclear Regulatory Commission (NRC) issued combined licenses (COLs) to allow Southern Nuclear Operating Company (SNC) and South Carolina Electric and Gas Company (SCE and G) to construct and operate AP1000 plants. Within this paper, the various factors that contribute to an unparalleled level of design, construction, delivery, and licensing certainty for any new AP1000 plant projects are described. These include: 1) How the AP1000 plant design development and reviews undertaken in the United States, China and Europe increase licensing certainty. 2) How the AP1000 passive plant robustness against extreme events that result in large loss of infrastructure further contributes to the licensing certainty in a post

    The AP600 design is based on providing a safe, simple, standardized, and economically competitive design with a high degree of operability and ease of maintenance. Design features such as component selection, layout, and standardization increase the probability that targeted repair times are achieved. Design requirements from the utility industry and industry design practices have established criteria for: layout, changeout and replacement of parts and components; access for major pieces of equipment; and vehicle passage. These features coupled with a solid reliability assurance and maintenance program will help the AP600 meet its objectives for operation and maintenance. The AP600 draws on the operating experience and lessons learned from the utility community through design workshops and design review interaction, as well as operating plant data from sources several sources. Internally, the AP600 program incorporates the resources of Westinghouse NSD (Nuclear Service Division), which for decades has provided refueling, steam generator, reactor coolant pump, and other operating plant services. Since the early phases of the design process, the AP600 Program has executed a comprehensive reliability, availability, and maintainability program (RAM) which dealt primarily with assessing and improving plant availability. In conjunction with this program a Probabilistic Risk Assessment (PRA) was performed and submitted to the NRC with the Standard Safety Analysis Report (SSAR) in June 1992. This paper describes how AP600 ensures that the plant has design features to enhance reliability, availability, and maintainability. The RAM program that brings the plant through the design certification phase is described

    A mixed methods study was undertaken to investigate the role of Assistant Practitioners (APs) in radiography from an AP perspective and to explore how their roles have been integrated into the radiography workforce across England. The quantitative survey was followed by a qualitative study utilising semi-structured interviews, findings of which are presented in this paper. Thirty eight face to face, semi-structured interviews were conducted. Thematic analysis allowed the researcher to report experiences and meanings for APs, through a process of identifying, analysis and reporting patterns. Three main themes and eight sub-themes emerged from the data analyses. The first theme showed how participants felt the AP role developed over time. AP practice revealed a range of roles and responsibilities which resulted in confusing boundaries. Participants felt uncertain about their future role as APs. The second theme reflected on the factors that influenced the participants' perceptions. Findings showed that the acceptance of APs changed over time. Participants believed that they were competent to perform their roles and responsibilities. The third and final theme focused on the facilitating and constraining factors in AP practice. Supervision was seen as a constraining internal factor highlighting the fact that supervision practices varied across departments. In conclusion findings have identified a need for revised supervisory standards to inform departmental protocols and procedures

    The AP600 Project is a passive pressurized water reactor power plant which is part of the Design Certification and First-of-a-Kind Engineering effort under the Advanced Light Water Reactor program. Included in this process is the design of the containment air filtration system which will be the subject of this paper. We will compare the practice used by previous plants with the AP600 approach to meet the goals of industry standards in sizing the containment air filtration system. The radiological aspects of design are of primary significance and will be the focus of this paper. The AP600 Project optimized the design to combine the functions of the high volumetric flow rate, low volumetric flow rate, and containment cleanup and other filtration systems into one multi-functional system. This achieves a more simplified, standardized, and lower cost design. Studies were performed to determine the possible concentrations of radioactive material in the containment atmosphere and the effectiveness of the purge system to keep concentrations within 10CFR20 limits and within offsite dose objectives. The concentrations were determined for various reactor coolant system leakage rates and containment purge modes of operation. The resultant concentrations were used to determine the containment accessibility during various stages of normal plant operation including refueling. The results of the parametric studies indicate that a dual train purge system with a capacity of 4,000 cfm per train is more than adequate to control the airborne radioactivity levels inside containment during normal plant operation and refueling, and satisfies the goals of ANSI/ANS-56.6-1986 and limits the amount of radioactive material released to the environment per ANSI/ANS 59.2-1985 to provide a safe environment for plant personnel and offsite residents.

    AP1000 nuclear power plant applies an integrated approach to establish equipment reliability classification, which includes probabilistic risk assessment technique, maintenance rule administrative, power production reliability classification and functional equipment group bounding method, and eventually classify equipment reliability into 4 levels. This classification process and result are very different from classical RCM and streamlined RCM. It studied the characteristic of AP1000 equipment reliability classification approach, considered that equipment reliability classification should effectively support maintenance strategy development and work process control, recommended to use a combined RCM method to establish the future equipment reliability program of AP1000 nuclear power plants.

    Objective: Biallelic mutations in the AP5Z1 gene encoding the AP-5 ζ subunit have been described in a small number of patients with hereditary spastic paraplegia (HSP) (SPG48); we sought to define genotype–phenotype correlations in patients with homozygous or compound heterozygous sequence variants predicted to be deleterious. Methods: We performed clinical, radiologic, and pathologic studies in 6 patients with biallelic mutations in AP5Z1. Results: In 4 of the 6 patients, there was complete loss of AP-5 ζ protein. Clinical features encompassed not only prominent spastic paraparesis but also sensory and motor neuropathy, ataxia, dystonia, myoclonus, and parkinsonism. Skin fibroblasts from affected patients tested positive for periodic acid Schiff and autofluorescent storage material, while electron microscopic analysis demonstrated lamellar storage material consistent with abnormal storage of lysosomal material. Conclusions: Our findings expand the spectrum of AP5Z1-associated neurodegenerative disorders and point to clinical and pathophysiologic overlap between autosomal recessive forms of HSP and lysosomal storage disorders.

    The lentiviruses HIV and simian immunodeficiency virus (SIV) subvert intracellular membrane traffic as part of their replication cycle. The lentiviral Nef protein helps viruses evade innate and adaptive immune defenses by hijacking the adaptor protein 1 (AP-1) and AP-2 clathrin adaptors. We found that HIV-1 Nef and the guanosine triphosphatase Arf1 induced trimerization and activation of AP-1. Here we report the cryo-electron microscopy structures of the Nef- and Arf1-bound AP-1 trimer in the active and inactive states. A central nucleus of three Arf1 molecules organizes the trimers. We combined the open trimer with a known dimer structure and thus predicted a hexagonal assembly with inner and outer faces that bind the membranes and clathrin, respectively. Hexagons were directly visualized and the model validated by reconstituting clathrin cage assembly. Arf1 and Nef thus play interconnected roles in allosteric activation, cargo recruitment, and coat assembly, revealing an unexpectedly intricate organization of the inner AP-1 layer of the clathrin coat.

    AP-2 may have a direct effect on the c-myc gene. Chromatin immunoprecipitation assays demonstrated that AP-2 proteins bound to a cluster of AP-2 binding sites located within a 2 kb upstream regulatory region of c-myc These results suggest that the negative regulation of AP-2 on c-MYC activity was achieved through binding of AP-2 protein to the c-myc gene. The effects of AP-2 on c-MYC induced ROS accumulation and apoptosis in epidermal keratinocytes are likely to play an important role in cell growth, differentiation and carcinogenesis of the skin.

    Full Text Available La celebración del III Concilio de Toledo —cuyo MCD aniversario acabamos de conmemorar— significó, por encima incluso del solemne refrendo a la previa conversión visigoda, el fin del tradicional distanciamiento entre las autoridades bárbaras y el clero hispano-romano. Un distanciamiento convertido en abierta hostilidad durante el reinado de Leovigildo a causa de su política religiosa, y de la actitud favorable al rebelde Hermenegildo (y en suma a Bizancio, de buena parte del episcopado católico. En ese sentido, el clima de «unanimidad y paz» que el reinado de Recaredo vino a inaugurar, y cuya mejor expresión es el propio III Concilio toledano, se caracterizarla por una progresiva integración de la Iglesia en el aparato de la nueva monarquía. Hasta el punto de alcanzarse una práctica simbiosis, ideológica como real, entre ambos poderes, que sólo la invasión musulmana pudo truncar.

    DNA binding by transcripton factor AP-1 was enhanced remarkably following kindling stimulation in rat amygdala. Maximum increase occurred 2 h after stimulation with return to baseline within 24 h. Supershift and western analyses revealed that 38,000 mol. wt Fos-related antigen and JunD were the main components of the evoked AP-1 complexes at the time their induction reached maximum. AP-1 induction 2 h after the last kindling stimulation was more prominent in samples from previously kindled rats than in those from non-kindled rats. This study sought to establish the role of AP-1 in plastic changes of the hippocampus associated with kindling. Male Sprague-Dawley rats were kindled from the left amygdala until they exhibited Racine [15] class 5 generalized seizures. Nuclear proteins were extracted from dorsal hippocampi obtained from 0 to 24 h after final stimulations. From these, we evaluated the temporal pattern of DNA binding by AP-1 using a gel mobility-shift assay with a {sup 32}P-labelled AP-1 probe. Supershift and western analyses were added to investigate components of the seizure-evoked AP-1 complexes. Our results suggest that the basal level of AP-1 complexes is not associated with the seizure susceptibility in kindling. However, development of kindling appears to facilitate stimulus-evoked AP-1 induction, probably via plastic changes in the central nervous system. AP-1 may mediate such changes by regulating expression of certain genes. (Copyright (c) 1997 Elsevier Science B.V., Amsterdam. All rights reserved.)
