    2014-10-01

    Full Text Available El papel del endotelio en la insuficiencia cardíaca (IC ha sido el centro de intensa investigación, puesto que tiene importantes implicaciones sistémicas expresadas en su efecto vasomotor, hemostático e inflamatorio. Existen diferencias individuales en el patrón de la disfunción endotelial de acuerdo a la etiología y severidad de la IC. La disfunción endotelial tiene un importante valor pronóstico en la IC y, aunque aún necesitamos conocer más aspectos de relevancia clínica, es evidente que esta condición se relaciona con desenlaces negativos en estos pacientes. Estamos a la espera de nuevos agentes farmacéuticos dirigidos específicamente al endotelio vascular. En esta revisión, nuestro objetivo es ofrecer un análisis crítico y contemporáneo de la evidencia disponible sobre las consecuencias patológicas y pronóstico de las anomalías endoteliales que definen el inicio, la historia natural y, en última instancia, los desenlaces en la IC.

    2013-01-01

    En las últimas décadas, la neurociencia y la psicología cognitiva nos ha permitido comenzar a entender la relación entre procesos psicológicos diversos y hasta sobre las bases neurológicas de las creencias, las emociones, los juicios y las decisiones morales. Pese a la aceptada distinción entre el carácter descriptivo de la ciencia y el normativo de la moralidad, algunos autores afirman que los resultados de los estudios neurocientíficos tienen implicaciones normativas.

    Full Text Available Las investigaciones sobre las implicaciones sociales de las nanotecnologías no han abordado el tema del empleo, a pesar de su importancia social. A partir del análisis de las características de los productos de la nanotecnología que están en el mercado, este artículo muestra que las nanotecnologías tendrán un impacto considerable en la distribución del empleo entre los sectores, en la división internacional del trabajo y en las calificaciones para las actividades, causando efectos desestabilizadores en el empleo a nivel nacional y global.

  6. Desarrollo multinivel: Implicaciones macro-regional, local y micro- regional

    2006-11-01

    Full Text Available Este trabajo se propone analizar las implicaciones del desarrollo en los niveles macro-regional, local y micro- regional, a partir de la hipótesis central de la teoría del desarrollo que plantea que el desarrollo económico traerá consigo el desarrollo político y social. Después de hacer de un acercamiento conceptual al desarrollo, se repasan brevemente las teorías del desarrollo existentes como herramientas de análisis de la realidad. En la discusión se concluye que los procesos de desarrollo locales y regionales requieren de una transformación sustancial de las relaciones negociadas entre los agentes económicos y los actores políticos. Ante el paulatino retroceso que en las sociedades contemporáneas está teniendo el Estado de bienestar, uno de los principales retos es el empoderamiento de las organizaciones sociales y comunitarias para que desempeñen activamente su rol en los procesos de desarrollo local y regional.

    1987-06-01

    The population of St Lucia was 123,000 in 1986, with an annual growth rate of 2%. The infant mortality rate stands at 22.2/1000 live births, and life expectancy is 70.3 years for males and 74.9 years for females. The literacy rate is 78%. St Lucia's labor force is allocated as follows: agriculture, 36.6%; industry and commerce, 20.1%; and services, 18.1%. The gross national product (GNP) was US$146 million in 1985, with an annual growth rate of 3% and a per capita GNP of $1071. St Lucia is a parliamentary democracy modeled on the British Westminster system. The island is divided into 16 parishes and 1 urban area (the capital, Castries). St Lucia is currently a politically stable country, although the high level of youth unemployment is a cause for concern. Ongoing stability may depend on the government's ability to provide services such as jobs and housing. The economy has evolved from a monocrop sugar plantation type to a diversified economy based on agriculture, industry, and tourism. Agriculture, dominated by the banana industry, is characterized by the participation of a large number of small and medium-sized enterprises. Industry is being encouraged through the provision of incentives such as tax rebates. The government is attempting to maintain a sound investment climate through a tripartite dialogue with the private sector and trade unions. Overall economic policy is predicated on the attraction of sound investments, by both local and foreign entities, to accelerate the rate of economic growth, solve the unemployment problem, and generate a solid balance-of-payments position.

    Full Text Available El objetivo del presente trabajo es analizar los factores que influyen en el uso de buscadores y su incidencia en el comportamiento de compra en Internet. El análisis de resultados obtenidos a partir de una muestra representativa de 485 compradores por Internet españoles, pone de manifiesto que los consumidores que consideran la comodidad, reducciones de precio y amplitud de surtido como motivaciones relevantes para realizar compras online presentan una mayor predisposición al uso de buscadores en la realización de sus compras virtuales. La experiencia como internauta y como comprador en Internet son factores que influyen negativamente en el uso de buscadores para la realización de compras virtuales. En cuanto a las implicaciones, los resultados no muestran una influencia significativa del uso de buscadores en el volumen de gasto en Internet.

    Full Text Available El trauma ocular cerrado según su grado puede ser ligero moderado o severo. En algunos casos permanece inadvertido o enmascarado y crea consecuencias por lo que debe ser investigado. El trauma tiene características y deja huellas, algunas evidentes y otras ocultas que pueden aparecer en la historia clínica o deben ser buscadas en el segmento anterior ocular en donde se pueden observar trastornos del reflejo pupilar, (incluye midriasis paralítica, laceraciones palpebrales, hemorragia orbitaria, hifema (hemorragia en cámara anterior y fracturas óseas, orbitaria o maxilofacial.

    Full Text Available Diversos estudios sitúan a la docencia universitaria como una de las profesiones con mayor riesgo a experimentar inestabilidad y estrés laboral. La presente investigación exploró el ni- vel de burnout y las habilidades en inteligencia emocional en una muestra de 60 profesores universitarios de tiempo completo de la Pontificia Universidad Católica del Ecuador, sede Ambato. Se realizaron análisis de mediación múltiple y se encontró que: a las tareas de in- vestigación y vinculación se asocian significativamente a burnout, y la tarea de docencia es percibida como desempeño óptimo, b la salud actúa como variable mediadora entre estrés laboral y burnout, y el género solo se relaciona con burnout, y c la regulación emocional media la relación entre desempeño docente y satisfacción laboral. Se discuten las implicaciones de estos hallazgos en la salud laboral de docentes universitarios.

  18. Implicaciones de la securitización en América desde la particularidad Colombiana

    Directory of Open Access Journals (Sweden)

    Nathaly Jiménez Reynales

    2004-01-01

    Full Text Available Este artículo da cuenta de las implicaciones que surgen a partir de un análisis constructivista de la relación constitutiva entre los temas de agenda de la política exterior de un país como Colombia y el resultado de su integración en la región. Ello explica que mientras exista un condicionante como la securitización en la política de un país será difícil concertar políticas comunes con otras naciones. El caso de las drogas ilícitas, por ejemplo, le ha generado al Estado colombiano problemas de coordinación entre la política antidrogas que adelanta y su capacidad de maniobra en un escenario específico como el andino. Igualmente, la actual política de defensa y seguridad democrática manifiesta una ruptura entre lo que se entiende como seguridad democrática y la percepción que la sociedad tiene de ella. Ambos casos ayudarán a comprender cómo al securitizar un asunto político el Estado puede perder su dirección tanto en el ámbito internacional como en el doméstico.

  19. Competencia cognitiva en penados primarios y reincidentes: implicaciones para la reeducación

    2014-01-01

    Full Text Available La probabilidad de reincidencia delictiva es aproximadamente tres veces mayor para los penados reincidentes que para los primarios. En esta línea, se sugiere una relación entre el grado de comportamiento antisocial y delictivo, y el nivel de desarrollo de la competencia cognitiva. Así, se prevé que los penados reincidentes presenten un menor desarrollo de la competencia cognitiva que los primarios. Para comprobar esta hipótesis, 104 penados, 54 primarios y 50 reincidentes, que no habían sido previamente objeto de un tratamiento penitenciario, fueron evaluados en atribución de la responsabilidad, autoconcepto, afrontamiento e inteligencia emocional. Los resultados mostraron que los penados reincidentes tenían menos desarrollado el autoconcepto y la inteligencia emocional que los primarios. Además, se observó una mayor tendencia en los reincidentes a afrontar las situaciones estresantes y de riesgo a través de estrategias no adaptativas (v.gr., centradas en las emociones, evitativas. Sin embargo, primarios y reincidentes se atribuyen por igual la responsabilidad. En suma, los penados reincidentes son menos competentes cognitivamente que los primarios. Se discuten las implicaciones de los resultados para la reeducación, resocialización y reinserción social de los penados.

    Full Text Available Las tecnologías de energía renovable como la eólica, la solar y la biomasa, hacen un uso del suelo más intenso que las de combustibles fósiles tradicionales y, geográficamente, sus implicaciones ambientales son más heterogéneas, por lo que presentan un gran desafío para las técnicas de evaluación de su ciclo de vida. Este trabajo presenta los resultados de una investigación bibliográfica alrededor de los siguientes temas: 1 cambios en el uso del suelo debido a la mayor producción de energía renovable; 2 impactos del uso de suelo; 3 variabilidad geográfica en el inventario de datos; y 4 efectos de la distribución de energía. Además, se revisa el grado de investigación que actualmente se aplica acerca de las tecnologías de energía renovable en campos como el eólico, el solar y la bioenergía y en la evaluación del ciclo de vida en general.

    2012-01-01

    Full Text Available La expansión de Aedes albopictus por el Levante español no ha cesado desde su primigenia detección en nuestro país en el año 2004, habiéndose constatado ya su presencia en las provincias de Girona, Barcelona, Tarragona, Castellón, Alicante y Murcia. La elevada sinantropía de la especie, unida al alto grado de antropofília y extensa capacidad vectorial para transmitir diversas arbovirosis, han propiciado el retorno al sur de Europa de ciclos de transmisión activa de enfermedades frecuentes en el pasado como el Dengue o la aparición de virosis tropicales inéditas hasta entonces como Chikungunya. El presente manuscrito analiza de forma pormenorizada las implicaciones para la salud pública de la previsible expansión de Ae. albopictus por gran parte del territorio peninsular, en el contexto climático y sociodemográfico actual. Adicionalmente, también se discuten diversas cuestiones relativas al control poblacional de la especie en ambientes urbanos y periurbanos, así como los datos preliminares existentes acerca de otros aedinos invasores de reciente hallazgo en el continente europeo.

    Directory of Open Access Journals (Sweden)

    Luz Esperanza Bohórquez

    2016-10-01

    Método: en el documento se revisan las características de los sistemas de complejidad creciente y se identifican los elementos que explican su capacidad de auto-organización. A partir de esta revisión se plantean las implicaciones de comprender a las organizaciones como sistemas de complejidad creciente, las cuales se articulan con recientes investigaciones que en ingeniería organizacional y gestión buscan incrementar la capacidad de adaptación del sistema. Resultados: se desarrolla una apreciación sobre las implicaciones en la ingeniería organizacional de diseñar organizaciones empresariales con mayor capacidad para auto-organizarse y de manera amplia de aprovechar la complejidad creciente del entorno. Conclusiones: la comprensión de las organizaciones empresariales como sistemas de complejidad creciente ofrece una perspectiva notoriamente distinta al paradigma tradicional el cual se han caracterizado por el enfoque reduccionista. A la fecha la investigación al respecto se encuentra en etapas tempranas y no existen modelos o evidencias empíricas que permitan corroborar de manera amplia y completa la fuerza de tales ideas. Sin embargo, los altos niveles de agilidad, flexibilidad y robustez que exhiben los sistemas auto-organizados permiten proyectar importantes campos de investigación alrededor del diseño de estructuras organizacionales flexibles, formas de gobernanza, toma decisiones en ausencia de controlador central, etc.

  11. La problematica de la demarcacion entre ciencia y pseudociencia y sus implicaciones en la educacion cientifica

    Jimenez Tolentino, Dinorah

    2011-12-01

    En la sociedad prevalece una tendencia generalizada hacia la inclusion de creencias y practicas pseudocientificas. Esta investigacion responde a la necesidad de analizar como la proliferacion de las pseudociencias afecta la vision que tienen los estudiantes universitarios sobre las ciencias naturales. A tales efectos, la investigadora describe las concepciones epistemologicas que tienen los estudiantes sobre las ciencias y las pseudociencias e identifica los criterios de demarcacion, entre un area y otra, que se derivan de estas concepciones. De igual modo, esta identifica las creencias y practicas pseudocientificas de mayor arraigo entre los estudiantes, destacando, a su vez, la razon de ser de las mismas. Por ultimo, la investigadora analiza las implicaciones educativas de la problematica de la demarcacion entre ciencia y pseudociencia. La investigacion es de naturaleza mixta, enmarcada en los paradigmas empirico- analitico y cualitativo. El proceso investigativo se llevo a cabo mediante la administracion del cuestionario Criterios para la demarcacion entre ciencia y pseudociencia. La parte cualitativa estuvo enmarcada en el diseno de estudio de caso, recopilando informacion mediante entrevistas semiestructuradas en dos grupos focales. La poblacion de estudio estuvo constituida por estudiantes universitarios del nivel subgraduado de la Universidad Central de Bayamon. Los resultados del estudio reflejaron las concepciones erroneas de los estudiantes sobre la naturaleza de las ciencias y las pseudociencias. Con respecto a la demarcacion entre ciencia y pseudociencia, el criterio imperante entre los universitarios es el de la verificabilidad, considerando la aplicacion del metodo cientifico como el metodo para demostrar la veracidad de las teorias cientificas. Las creencias y practicas pseudocientificas no son muy frecuentes entre los universitarios. Estos atribuyen las mismas a la prevalencia de elementos supersticiosos y al engano a que es sometida la poblacion

    2016-09-01

    Full Text Available La presente colaboración aborda algunos aspectos postulados por Sylos Labini en su interpretación de la economía de Carlos Marx, sin duda polémica pero necesaria. Para ello se retoma la amplia discusión teórica realizada en torno a esos temas por varios académicos, que de una manera u otra, han participado e influido en dicho debate. Esta reflexión, importante en sí misma, se vuelve imprescindible en referencia a determinadas implicaciones de gran envergadura sobre la aplicación de la política económica impuesta en los últimos más de 25 años en la Unión Europea, bajo los estrechos criterios de la política fiscal y monetaria impuesta. El autor expresa su opinión a título personal. Este ensayo es una traducción realizada por Glenda Lao Largaespada y Michele Cingolani y revisada por el autor de un artículo publicado con el mismo título en el vol. 68, n. 269 (2015, pp. 81- 147 de Moneta e Credito.

  13. Multicultura e interculturalidad: implicaciones de una ausencia en la educación

    Fernando Carlos Aguero-Contreras

    2016-06-01

    Full Text Available Resumen Reflexión teórica desde las perspectivas sociológica – antropológica de la educación, sustentada en los enfoques de la multicultura e interculturalidad. Se parte de varios estudios realizados en la residencia estudiantil de la Universidad de Cienfuegos, al centro - sur de Cuba. Estos han combinados análisis cuantitativos y cualitativos, considerando variables e indicadores socio demográficos, relacionados con la satisfacción en el acceso a la cultura, la salud, las relaciones y dinámicas sociales, mediadas por una estructura social clasista y sociocultural que distingue especificidades en la biografía cultural de individuos y grupos. Se concedió importancia a la significación dada a la residencia como escenario relevante de la vida educacional, las percepciones de las relaciones múltiples y diversas entre los grupos que tienen presencia en ella, así como los niveles de diálogos en los ámbitos académicos, científicos y sociales. Se analizaron varios documentos, y se realizaron observaciones, entrevistas estructuradas y en profundidad. Desde este contexto se muestran las implicaciones del déficit teórico en la gestión formativa en la residencia universitaria, limitando el alcance del proyecto educativo como concreción curricular, para el desarrollo de procesos socializadores más coherentes. Se concluye que la ausencia de estas perspectivas teóricas en la educación superior posibilitaron que la visión política ocupara la primera interpretación del proceso, expresada en la acción solidaria y aun cuando se muestran resultados concretos de importancia en cuanto al número de alumnos graduados, el proceso formativo fue limitado en el diálogo profundo, la socialización cultural para la lograr la unidad en la diversidad.

    RESUMEN

    En el presente estudio administramos a 34 entrenadores de balonmano un cuestionario de medida de los criterios de éxito deportivo (POSQ y otro de la importancia otorgada a diferentes variables de la metodología de entrenamiento con el fin de analizar el papel predictor de la orientación de meta de los entrenadores sobre la valoración de aspectos determinantes del entrenamiento. Los resultados de los Análisis de Regresión indicaron que la orientación a la tarea se correspondía con la concesión de importancia a: La especificidad del entrenamiento; la agrupación de los jugadores según su nivel de destreza; el control y anotación de los progresos de los jugadores; la libertad del jugador para ejecutar y decidir; y la consideración de la competición como un medio y no como un fin. La orientación al ego predijo positivamente la concesión de importancia a la variedad de ejercicios y la comunicación con los padres para resolver problemas y negativamente la concesión de importancia a la libertad del jugador para ejecutar y decidir. Las implicaciones motivacionales de estos resultados se analizan a la luz de la teoría de la motivación de logro (Nicholls, 1984a,b y la teoría de la autodeterminación (Deci y Ryan, 1985, 1991.
    PALABRAS CLAVE: Motivación de logro, autodeterminación, metodología de entrenamiento.

    Full Text Available Normal 0 21 false false false ES-CO X-NONE X-NONE MicrosoftInternetExplorer4 Ante la necesidad mundial por encontrar fuentes de energía alternativas, los biocombustibles se han constituido en la última década como una posible respuesta. Su creciente demanda se ha visto reflejada en la expansión de los cultivos utilizados como materias primas, lo cual tiene implicaciones en varios frentes: los cambios de uso de la tierra, servicios ecosistémicos relacionados con el recurso hídrico, las emisiones de Gases Efecto Invernadero (GEI, la seguridad alimentaria y la propiedad de la tierra. El presente artículo tiene como objetivo presentar un análisis crítico de estos temas a partir de la revisión de la literatura internacional y abordar el caso colombiano, en particular la expansión de los cultivos de palma africana y sus implicaciones sociales. Los principales resultados dejan ver que la expansión de los cultivos se direccionará hacia los países del trópico, lo cual genera  impactos negativos al intensificar la competencia por el agua y la tierra en regiones caracterizadas por su alta vulnerabilidad ecosistémica y social. Adicionalmente se observa la necesidad de mejorar los sistemas de información y de refinar metodologías y modelos que permitan evaluar con mayor precisión los impactos de la producción de biocombustibles sobre el bienestar humano.

    Full Text Available En el presente estudio abordaremos dos de las principales concepciones sobre los mecanismos implicados en la construcción significativa del mundo. Hablamos de la Teoría de las Representaciones Sociales (TRS, formulada desde la psicología, y del marco teórico de lo imaginario, formulado principalmente desde la antropología y la filosofía. Procederemos exponiendo, primero, la TRS y, posteriormente, los acercamientos al marco teórico de lo imaginario desde diferentes disciplinas, para señalar las aportaciones que ofrece este último a la psicología social, aportaciones éstas que complementan las de la TRS. Así, este estudio tiene como objetivos realizar un análisis teórico de la TRS y del marco teórico de lo imaginario y especificar las contribuciones e implicaciones del marco teórico de lo imaginario a la psicología social (y, más concretamente, a la psicología cultural de modo a observar cómo el concepto de imaginario social incluye y trasciende al de representación social(RS. Consideraremos las implicaciones ontológicas, epistemológicas, metodológicas y para la salud de la utilización del marco teórico de lo imaginario en la psicología cultural. En este sentido, propondremos la adopción de dicho concepto por la psicología, considerando que el mismo es fundamental por su capacidad explicativa, comprensiva, interpretativa y crítica.

Este cambio implicó una reducción de la tasa de desempleo del orden de dos puntos porcentuales. En este documento contrastamos el caso Colombiano con las experiencias de otros países en términos de la transformación metodológica y sus implicaciones empíricas. Posteriormente, evaluamos el soporte empírico del cambio de metodología. Nuestros resultados sugieren implicaciones específicas sobre el desempleo estructural y su relación con el perfil educativo de los desempleados; por lo tanto, cuestionan la aplicación práctica de la definición estándar de desempleo de la OIT al caso colombiano.

    2017-06-01

    The genome constitution of tetraploid Roegneria alashanica Keng has been in question for a long time. Most scientific studies have suggested that R. alashanica had two versions of the St genome, St 1 St 2 , similar to that of Pseudoroegneria elytrigioides (C. Yen & J.L. Yang) B.R. Lu. A study, however, concluded that R. alashanica had the StY genome formula typical for tetraploid species of Roegneria. For the present study, R. alashanica, Elymus longearistatus (Bioss.) Tzvelev (StY genomes), Pseudoroegneria strigosa (M. Bieb.) Á. Löve (St), Pseudoroegneria libanoctica (Hackel) D.R. Dewey (St), and Pseudoroegneria spicata (Pursh) Á. Löve (St) were screened for the Y-genome specific marker B14(F+R) 269 . All E. longearistatus plants expressed intense bands specific to the Y genome. Only 6 of 10 R. alashanica plants exhibited relatively faint bands for the STS marker. Previously, the genome in species of Pseudoroegneria exhibiting such faint Y-genome specific marker was designated as St Y . Based on these results, R. alashanica lacks the Y genome in E. longearistatus but likely possess two remotely related St genomes, St and St Y . According to its genome constitution, R. alashanica should be classified in the genus Pseudoroenera and given the new name Pseudoroegneria alashanica (Keng) R.R.-C. Wang and K.B. Jensen.

    Full Text Available Uno de los objetivos de la política universitaria a nivel nacional e internacional ha sido la diversificación de las vías de entrada a la universidad para favorecer el acceso más generalizado a la educación superior. Sin embargo, el establecimiento de políticas de acceso debe ir acompañado de medidas para garantizar la permanencia en el sistema. La orientación es uno de los instrumentos más significativos. El artículo presenta los resultados de una investigación longitudinal sobre los procesos de transición y persistencia de una cohorte de estudiantes de ADE y Pedagogía de la Universidad de Barcelona que iniciaron los estudios en el año 2010. Los datos confirman que las situaciones de retraso académico, fracaso y abandono son significativamente superiores entre los estudiantes que accedieron a través de las vías no convencionales (específicamente aquellos procedentes de las vías CFGS, mayores de 25 años y 45 años. A partir de los resultados procedentes de las bases de datos institucionales y de los cuestionarios de seguimiento, se discute las implicaciones para el establecimiento de acciones de orientación y tutoría que contribuyan a la verdadera equidad del sistema.

    2008-07-01

    Full Text Available Se lleva a cabo una revisión crítica de la hipótesis traumática en el estudio de las experiencias eróticas tempranas con personas más mayores. Esta hipótesis, la más habitual en la literatura científica, consiste en dar por cierto que son en su mayoría experiencias graves y de serias consecuencias negativas a corto y/o largo plazo. Cuestionaremos su fundamentación empírica, para después pasar a las implicaciones científicas y profesionales surgidas de otra lectura de los datos disponibles. Para ello se analizan críticamente nueve revisiones previas sobre la cuestión, publicadas entre 1981 y 1998. Esta revisión de revisiones sugiere que estaría perfectamente sustentada la hipótesis de que en la gran mayoría de los casos no suelen producirse daños serios ni mucho menos permanentes en los implicados. El análisis invita a un replanteamiento teórico, epistemológico y tecnológico de la investigación y la intervención social.

    2012-01-01

    Las investigaciones sobre la violencia entre parejas sugieren que las mujeres hispanas están siendo afectadas desproporcionadamente por la ocurrencia y consecuencias de este problema de salud pública. El objetivo del presente artículo es dar a conocer el estado del arte en relación a la epidemiologia, consecuencias y factores de riesgo para VP entre mujeres Hispanas, discutiendo las implicaciones para la investigación y la práctica. Investigaciones han demostrado una fuerte asociación del status socioeconómico, abuso de droga y el alcohol, la salud mental, aculturación, inmigración, comportamientos sexuales riesgosos e historia de abuso con la violencia entre parejas. Sin embargo, más estudios se deben llevar a cabo para identificar otros factores de riesgos y de protección a poblaciones hispanas no clínicas. Mientras que el conocimiento sobre la etiología de la VP entre mujeres Hispanas se expanda, enfermeras y otros profesionales de la salud deben desarrollar, implementar y evaluar estrategias culturalmente adecuadas para la prevención primaria y secundaria de la violencia entre pareja.

    Full Text Available La diversidad genética le confiere a Plasmodium falciparum la capacidad de evadir la respuesta inmune del hospedero y producir variantes resistentes a medicamentos y a vacunas, aspectos que juegan un papel importante en el establecimiento de medidas de control contra la malaria. Diferentes autores han documentado la existencia de diversas cepas o clones de P. falciparum, cuya diversidad genética se ha confirmado a través de distintos ensayos de PCR (reacción en cadena de la polimerasa. Numerosas investigaciones realizadas en poblaciones con diferente grado de transmisión de malaria han mostrado la relación existente entre la estructura de la población de P. falciparum y la epidemiología de la enfermedad. En este artículo se describen las fases del ciclo de vida en las que los eventos de recombinación originan la diversidad genética de P. falciparum, se revisan los estudios realizados sobre este aspecto en regiones con diferentes grados de endemicidad, así como sobre sus implicaciones en la adquisición de inmunidad y en el desarrollo de medidas de control.

Estudio que se realiza bajo la modalidad del paradigma crítico reflexivo, en tanto que el nuevo ordenamiento social hace de las universidades, entidades más complejas, de variadas funciones, de mayor consumo de recursos, diluyendo su identidad en nuevas perspectivas. Se evidencia al currículo como el eje central del proceso de reforma, centrado en valores, el cual abre la posibilidad de abordar aspectos vitales tanto individual como grupal, transferibles a la sociedad en su conjunto. La reforma implica la diversidad y la transversalidad, reflejada en la concreción de un conjunto de medidas y de acciones, que reconoce la heterogeneidad de los grupos, de los valores, de la solidaridad, la tolerancia y el respeto a lo individual. La discusión revela el compromiso de las universidades para desarrollar un profundo trabajo epistemológico de investigación y redefinición de su actuar, como mecanismo para conectar los saberes a la complejidad del tejido de una realidad impregnada por los cambios, la complementariedad y la multiculturalidad.

    2015-04-01

    Full Text Available Las condiciones ergonómicas de mobiliario y de equipos, como también la postura incorrecta al estar en posición sedente, de pie o cargando algún peso pueden generar dolores o complicaciones osteomusculares. Dentro de estas, la cabeza hacia adelante es una alteración común detectada en la evaluación postural realizada por los fisioterapeutas. Esta suele asociarse a cambios mecánicos del cuello y columna vertebral, los cuales alteran la funcionalidad de los individuos, causándole discapacidad pues compromete el movimiento de hombros, la movilidad de la articulación temporomandibular, la mecánica respiratoria, desarrollando imbalances musculares, mareos, disfunción vestibular, aumenta el riesgo de fracturas y se asocia con procesos dolorosos como la cervicalgia, dorsalgia y lumbalgia. Por tanto el siguiente artículo tiene por objetivo revisar la fisiopatogénia de la cabeza hacia adelante, desde una perspectiva biomecánica, analizando las implicaciones de esta alteración postural sobre el movimiento corporal humano, proporcionando así herramientas de análisis para el abordaje fisioterapéutico.

    Full Text Available En este trabajo se analizan los datos de un estudio longitudinal a largo plazo con el objetivo de examinar las implicaciones de los rasgos psicopáticos infanto-juveniles, evaluados a través de la mCPS (modified Child Psychopathy Scale, en la conducta antisocial en la adolescencia. Se analizan los datos recogidos en 141 niños (edad media = 7.80, que fueron seguidos seis y diez años más tarde. Los resultados muestran que los niños con altas puntuaciones en rasgos psicopáticos presentan en la adolescencia temprana niveles relativamente altos de problemas de conducta. Además, a lo largo de la adolescencia se produce en ellos un mayor incremento en implicación con amigos antisociales, consumo de cannabis y agresión proactiva. Así, los resultados muestran que los rasgos psicopáticos medidos en la niñez se asocian con un desarrollo más desfavorable, particularmente en indicadores que, como la agresión proactiva, se han vinculado clásicamente a la personalidad psicopática en adultos.

En primer lugar, describiremos de manera muy breve algunos de los principales conceptos técnicos de la teoría (por ejemplo, los conceptos de transformación de funciones y de operante generalizada. Posteriormente, propondremos cuatro causas por las cuales se generan los problemas psicológicos derivadas de una aproximación a la psicopatología humana generada desde la RFT. Dichas causas tienen que ver con los contextos verbales de la literalidad, la formación de categorías y por consiguiente la evaluación y comparación, el contexto de la búsqueda de coherencia y de dar razones y finalmente con el control de los eventos privados. Por último, se expondrán las amplias implicaciones clínicas de los conceptos de contexto relacional y contexto funcional, usando ejemplos clínicos relevantes y clasificando diferentes terapias en función de cual es su objetivo principal: la alteración del contexto funcional o del contexto relacional de redes relacionales.

    Allen, M.D.; Stockman, H.W.; Reil, K.O.; Grimley, A.J.; Camp, W.J.

    1988-01-01

    Two experiments (ST-1 and ST-2) have been performed in the Annular Core Research Reactor (ACRR) at Sandia National Laboratories (SNLA) to obtain time-resolved data on the release of fission products from irradiated fuels under light water reactor (LWR) severe accident conditions. Both experiments were conducted in a highly reducing environment at maximum fuel temperatures of greater than 2400 K. These experiments were designed specifically to investigate the effect of increased total pressure on fission product release; ST-1 was performed at approximately 0.16 MPa and ST-2 was run at 1.9 MPa, whereas other parameters were matched as closely as possible. Release rate data were measured for Cs, I, Ba, Sr, Eu, Te, and U. The release rates were higher than predicted by existing codes for Ba, Sr, Eu, and U. Te release was very low, but Te did not appear to be sequestered by the zircaloy cladding; it was evenly distributed in the fuel. In addition, in posttest analysis a unique fuel morphology (fuel swelling) was observed which may have enhanced fission product release, especially in the high pressure test (ST-2). These data are compared with analytical results from the CORSOR correlation and the VICTORIA computer model

    Full Text Available La investigación analiza la peligrosidad y exposición de las precipitaciones extremas y sus implicaciones en la evaluación y zonificación de los procesos de remoción en masa en la ciudad de Tampico, localizada en la cuenca baja del río Pánuco, México. La metodología emplea un Sistema de Información Geográfica para la agregación de los datos hidrometeorológicos y geomorfológicos, posibilitando el análisis de las variaciones espacio-temporales de las precipitaciones extremas, y sus implicaciones en la evaluación y zonificación de los procesos de remoción en masa, necesarios para la planificación urbana de Tampico. Los resultados indican que la distribución de las precipitaciones extremas favorece la alta agresividad climática, determinante de los procesos de erosión del suelo y de los peligros geomorfológicos, como desprendimientos y flujos de detritos, en el área de estudio. Asimismo, en los próximos años se prevé el aumento de los procesos de remoción en masa asociados a factores ambientales, por un incremento de la ocurrencia e intensidad de las precipitaciones extremas, y a factores antrópicos, por el crecimiento de la población y viviendas expuestas a áreas inestables.

    There is growing concern about the spreading of human microorganisms in relatively untouched ecosystems such as the Antarctic region. For this reason, three pinniped species (Leptonychotes weddellii, Mirounga leonina and Arctocephalus gazella) from the west coast of the Antartic Peninsula were analysed for the presence of Escherichia spp. with the recovery of 158 E. coli and three E. albertii isolates. From those, 23 harboured different eae variants (α1, β1, β2, ε1, θ1, κ, ο), including a bfpA-positive isolate (O49:H10-A-ST206, eae-k) classified as typical enteropathogenic E. coli. Noteworthy, 62 of the 158 E. coli isolates (39.2%) exhibited the ExPEC status and 27 (17.1%) belonged to sequence types (ST) frequently occurring among urinary/bacteremia ExPEC clones: ST12, ST73, ST95, ST131 and ST141. We found similarities >85% within the PFGE-macrorrestriction profiles of pinniped and human clinic O2:H6-B2-ST141 and O16:H5/O25b:H4-B2-ST131 isolates. The in silico analysis of ST131 Cplx genomes from the three pinnipeds (five O25:H4-ST131/PST43-fimH22-virotype D; one O16:H5-ST131/PST506-fimH41; one O25:H4-ST6252/PST9-fimH22-virotype D1) identified IncF and IncI1 plasmids and revealed high core-genome similarities between pinniped and human isolates (H22 and H41 subclones). This is the first study to demonstrate the worrisome presence of human-associated E. coli clonal groups, including ST131, in Antarctic pinnipeds.

    2008-01-01

    Full Text Available Se lleva a cabo una revisión crítica de la hipótesis traumática en el estudio de las experiencias eróticas tempranas con personas más mayores. Esta hipótesis, la más habitual en la literatura científica, consiste en dar por cierto que son en su mayoría experiencias graves y de serias consecuencias negativas a corto y/o largo plazo. Cuestionaremos su fundamentación empírica, para después pasar a las implicaciones científicas y profesionales surgidas de otra lectura de los datos disponibles. Para ello se analizan críticamente nueve revisiones previas sobre la cuestión, publicadas entre 1981 y 1998. Esta revisión de revisiones sugiere que estaría perfectamente sustentada la hipótesis de que en la gran mayoría de los casos no suelen producirse daños serios ni mucho menos permanentes en los implicados. El análisis invita a un replanteamiento teórico, epistemológico y tecnológico de la investigación y la intervención social.

    Full Text Available Las funciones ejecutivas implican un amplio rango de habilidades relacionadas con la regulación del pensamiento, el comportamiento y el propio estado emocional. Teniendo en cuenta la variedad de componentes que forman este constructo, no es sorprendente que su evaluación plantee ciertas dificultades. En este sentido, pese a que numerosos estudios han mostrado la importancia de dichos componentes como determinantes del desempeño académico y social, así como su utilidad en el diagnóstico y la intervención en diversas problemáticas durante la infancia y la adolescencia, aspectos como la validez ecológica de las medidas tradicionalmente empleadas para su evaluación, imponen hoy ciertas limitaciones a la validez y generalización de los resultados obtenidos en este ámbito. El objetivo de este trabajo es analizar las características de las medidas de evaluación más ampliamente empleadas y su grado de aplicabilidad en contextos clínicos y educativos, de lo cual se desprenden una serie de implicaciones prácticas.

    Full Text Available La suavidad de la carne: implicaciones físicas y bioquímicas asociadas al manejo y proceso agroindustrial. Actualmente, el problema de la suavidad de la carne representa una gran preocupación entre los productores, dado que esta variable ha demostrado ser el principal criterio con base al cual los consumidores juzgan la calidad de la carne. El problema es especialmente importante si se considera que una de cada cuatro degustaciones de la carne resultan insatisfactorias para el consumidor. Este trabajo abordó los principales aspectos asociados con la suavidad de la carne tales como la estructura y composición de la carne, el fenómeno de la contracción muscular, los cambios bioquímicos post mortem como el rigor mortis y la maduración, y el efecto general debido a las operaciones del procesamiento industrial como la cocción y el congelamiento. Métodos generales para el mejoramiento de la suavidad son discutidos, así como la actividad bioquímica e importancia de las enzimas CALPAINAS (calcium ion dependent papain like cisteine proteases.

    Full Text Available Las sociedades que cuentan con abundantes recursos naturales no renovables pueden transformar dicho capital natural en otros tipos de capital (p. ej. humano, producido, infraestructura a través de diferentes canales. Para los gobiernos que deben administrar la riqueza de los recursos naturales, la sustitución de un tipo de capital –que se agota a medida que se explota– por otros capitales sostenibles, es un reto de política pública. Uno de los canales de transformación lo constituye la creación de encadenamientos productivos –“hacia adelante” y “hacia atrás”– entre el sector extractivo y otros sectores económicos. Este artículo tiene dos objetivos: i identificar los principales cuellos de botella y factores de éxito para el desarrollo de proveedores nacionales y locales para el sector extractivo colombiano y ii las implicaciones de política pública relacionadas con la promoción de encadenamientos productivos entre los sectores mineros y de hidrocarburos, y otros sectores en Colombia.

    The Fort St. Vrain High Temperature Gas Cooled Reactor core performance has been evaluated during the startup testing phase of the reactor operation. The reactor is graphite moderated, helium cooled, and uses coated particle fuel and on-line flow control to each of the 37 refueling regions. Principal objectives of startup testing were to determine: core and control system reactivity, radial power distribution, flow control capability, and initial fission product release. Information from the core demonstrates that Technical Specifications are being met, performance of the core and fuel is as expected, flow and reactivity control are predictable and simple for the operator to carry out

  7. Special report: Mt. St. Helens

    Science.gov (United States)

    Mt. St Helens Volcano, Cascade Range, Southern Washington, USA (46.20°N, 122.18°W.) All times are local (GMT - 7 h through October 24, GMT - 8 h thereafter. Lava extrusion that probably began October 30 added a new lobe to the composite dome in the crater of Mt. St. Helens. After lava extrusion ended September 10 (see September 22 Eos), rates of deformation in the crater remained low for several weeks, as they had after earlier extrusion episodes. Sulfur dioxide emission ranged from 70 to 190 tons per day between October 9 and 24, but showed no particular trends. Inflation of the dome has caused small thrust faults to form in the surrounding crater floor. In early October the most active thrust, south of the dome, was moving at about 1.5 cm/d, and stations on the north crater rampart showed outward movement of about 0.5 cm/d. By October 24 these rates had increased to 14.5 and 3.5-4 cm/d, respectively, and leveling profiles perpendicular to the dome showed that crater floor tilt rates had reached 400-500 μrad/d, prompting the U.S. Geological Survey (USGS) to issue an advisory prediction of renewed lava extrusion within the next two weeks.

    Full Text Available Translations were a crucial channel for the reception of Italian Humanism in the Iberian Peninsula. This intellectual activity not only led to the recuperation of a significant part of the classical Greco-Roman legacy, but also fomented engagement with the works and ideas of contemporary Italian authors. On the one hand, this article underscores the critical role of translation in cultural transfers between both peninsulas and shows the change in authors selected to translate over the course of fifteenth century. On the other hand, it analyzes the implications of these author selections, arguing that they reveal at once an ideological transformation, a change in the conception of the very act of translation, and the adoption of new terminology.Las traducciones constituyeron uno de los canales prioritarios en la recepción del humanismo italiano en la Península Ibérica. A través de esta actividad intelectual, no sólo se recuperó una parte considerable del legado clásico grecolatino, sino que propició un acercamiento a la obra y a las ideas de los autores italianos contemporáneos. Por un lado, el presente trabajo insiste en el papel central de la traducción en el marco de la transferencia cultural entre ambas penínsulas y evidencia el cambio en la selección de los autores traducidos a lo largo del siglo XV; por otro lado, se analizan las implicaciones de dichas elecciones que, además de constituir una transformación a nivel ideológico, supusieron un cambio en la concepción de la actividad de la traducción y en la adopción de una nueva terminología.

Con el propósito de conocer este fenómeno, la presente investigación tuvo como objetivo estudiar la legitimación de capitales y sus implicaciones económicas, tomando en consideración los constructos teóricos establecidos por los autores Cano y Lugo (2010, Perotti (2009, y Del Cid (2007. Metodológicamente, el estudio es una revisión documental y como instrumento de recolección de datos se acudió al uso del resumen analítico y el análisis crítico. Entre las consideraciones finales, este quebrantamiento normativo presenta efectos adversos sobre la economía de una nación, que pueden variar de acuerdo a las características particulares de cada país, dentro de las consecuencias más resaltantes destacan: incide en la volatilidad de la economía, repercute en el establecimiento de las políticas económicas, así como en la capacidad productiva nacional, promueve la competencia desleal, genera insatisfacción entre los sectores productivos, disminuye la credibilidad de las instituciones, desmejora la libre oferta y demanda de los productos de consumo masivo. No obstante, puede representar ficticiamente soluciones a problemas económicos, como la generación de empleo, el aumento en la aplicación de nueva tecnología en la producción agrícola, crecimiento de la construcción de infraestructuras, y hace visible un desarrollo económico del país que la sufre.

    1998-01-01

    Public Service Company of Colorado (PSCo), owner of the Fort St. Vrain nuclear generating station, achieved its final decommissioning goal on August 5, 1997 when the Nuclear Regulatory Commission terminated the Part 50 reactor license. PSCo pioneered and completed the world's first successful decommissioning of a commercial nuclear power plant after many years of operation. In August 1989, PSCo decided to permanently shutdown the reactor and proceed with its decommissioning. The decision to proceed with early dismantlement as the appropriate decommissioning method proved wise for all stake holders - present and future - by mitigating potential environmental impacts and reducing financial risks to company shareholders, customers, employees, neighboring communities and regulators. We believe that PSCo's decommissioning process set an exemplary standard for the world's nuclear industry and provided leadership, innovation, advancement and distinguished contributions to other decommissioning efforts throughout the world.

  4. Galleria mellonella infection model demonstrates high lethality of ST69 and ST127 uropathogenic E. coli.

    Directory of Open Access Journals (Sweden)

    Majed F Alghoribi

    Full Text Available Galleria mellonella larvae are an alternative in vivo model for investigating bacterial pathogenicity. Here, we examined the pathogenicity of 71 isolates from five leading uropathogenic E. coli (UPEC lineages using G. mellonella larvae. Larvae were challenged with a range of inoculum doses to determine the 50% lethal dose (LD50 and for analysis of survival outcome using Kaplan-Meier plots. Virulence was correlated with carriage of a panel of 29 virulence factors (VF. Larvae inoculated with ST69 and ST127 isolates (10(4 colony-forming units/larvae showed significantly higher mortality rates than those infected with ST73, ST95 and ST131 isolates, killing 50% of the larvae within 24 hours. Interestingly, ST131 isolates were the least virulent. We observed that ST127 isolates are significantly associated with a higher VF-score than isolates of all other STs tested (P≤0.0001, including ST69 (P<0.02, but one ST127 isolate (strain EC18 was avirulent. Comparative genomic analyses with virulent ST127 strains revealed an IS1 mediated deletion in the O-antigen cluster in strain EC18, which is likely to explain the lack of virulence in the larvae infection model. Virulence in the larvae was not correlated with serotype or phylogenetic group. This study illustrates that G. mellonella are an excellent tool for investigation of the virulence of UPEC strains. The findings also support our suggestion that the incidence of ST127 strains should be monitored, as these isolates have not yet been widely reported, but they clearly have a pathogenic potential greater than that of more widely recognised clones, including ST73, ST95 or ST131.

    The St genome is one of the most fundamental genomes in Triticeae. Repetitive sequences are widely used to distinguish different genomes or species. The primary objectives of this study were to (i) screen a new sequence that could easily distinguish the chromosome of the St genome from those of other genomes by fluorescence in situ hybridization (FISH) and (ii) investigate the genome constitution of some species that remain uncertain and controversial. We used degenerated oligonucleotide primer PCR (Dop-PCR), Dot-blot, and FISH to screen for a new marker of the St genome and to test the efficiency of this marker in the detection of the St chromosome at different ploidy levels. Signals produced by a new FISH marker (denoted St 2 -80) were present on the entire arm of chromosomes of the St genome, except in the centromeric region. On the contrary, St 2 -80 signals were present in the terminal region of chromosomes of the E, H, P, and Y genomes. No signal was detected in the A and B genomes, and only weak signals were detected in the terminal region of chromosomes of the D genome. St 2 -80 signals were obvious and stable in chromosomes of different genomes, whether diploid or polyploid. Therefore, St 2 -80 is a potential and useful FISH marker that can be used to distinguish the St genome from those of other genomes in Triticeae.

    Pamies, David; Hartung, Thomas

    2017-01-17

    There is no good science in bad models. Cell culture is especially prone to artifacts. A number of novel cell culture technologies have become more broadly available in the 21st century, which allow overcoming limitations of traditional culture and are more physiologically relevant. These include the use of stem-cell derived human cells, cocultures of different cell types, scaffolds and extracellular matrices, perfusion platforms (such as microfluidics), 3D culture, organ-on-chip technologies, tissue architecture, and organ functionality. The physiological relevance of such models is further enhanced by the measurement of biomarkers (e.g., key events of pathways), organ specific functionality, and more comprehensive assessment cell responses by high-content methods. These approaches are still rarely combined to create microphysiological systems. The complexity of the combination of these technologies can generate results closer to the in vivo situation but increases the number of parameters to control, bringing some new challenges. In fact, we do not argue that all cell culture needs to be that sophisticated. The efforts taken are determined by the purpose of our experiments and tests. If only a very specific molecular target to cell response is of interest, a very simple model, which reflects this, might be much more suited to allow standardization and high-throughput. However, the less defined the end point of interest and cellular response are, the better we should approximate organ- or tissue-like culture conditions to make physiological responses more probable. Besides these technologic advances, important progress in the quality assurance and reporting on cell cultures as well as the validation of cellular test systems brings the utility of cell cultures to a new level. The advancement and broader implementation of Good Cell Culture Practice (GCCP) is key here. In toxicology, this is a major prerequisite for meaningful and reliable results, ultimately

    Full Text Available Under the European Energy Performance of Buildings Directive, the Member States must develop methods to certify energy efficiency of buildings. Calener-VYP v1.0 is the only Spanish official tool to certify a high energy efficiency performance of residential buildings, through the general option. It has two indicators implemented, CO2 emissions and primary energy consumption. However, in the process of energy rating a building, only the CO2 emissions indicator is considered. The economic consequences of this are studied, by means of simulating real properties with different construction assemblies and building services in the twelve Spanish climatic zones and calculating their costs. The results show that having a better energy rate in Calener VYP does not necessarily entail a lower consumption cost. Therefore, it is necessary to include the annual primary energy consumption indicator, because its absence involves that costs cannot be used as an argument when promoting energy efficiency among users.

    Bajo la Directiva Europea sobre eficiencia energética de los edificios, los Estados Miembros deben desarrollar procedimientos para certificar energéticamente los edificios. Calener-VYP v1.0 es la única herramienta oficial española para certificar una elevada aptitud en eficiencia energética de edificios residenciales, por el método general. Tiene dos indicadores implementados, emisiones de CO2 y consumo de energía primaria. Sin embargo, en el proceso de otorgar la calificación energética, solamente se consideran las emisiones de CO2. Las implicaciones económicas de esto se estudian simulando viviendas con diferentes características constructivas e instalaciones en las doce zonas climáticas españolas y calculando sus costes. Los resultados muestran que una mejor calificación energética en Calener-VYP no implica necesariamente un menor coste de consumo energético. Por tanto, es necesario

  19. Meteor detection on ST (MST) radars

    International Nuclear Information System (INIS)

    Avery, S.K.

    1987-01-01

    The ability to detect radar echoes from backscatter due to turbulent irregularities of the radio refractive index in the clear atmosphere has lead to an increasing number of established mesosphere - stratosphere - troposphere (MST or ST) radars. Humidity and temperature variations are responsible for the echo in the troposphere and stratosphere and turbulence acting on electron density gradients provides the echo in the mesosphere. The MST radar and its smaller version, the ST radar, are pulsed Doppler radars operating in the VHF - UHF frequency range. These echoes can be used to determine upper atmosphere winds at little extra cost to the ST radar configuration. In addition, the meteor echoes can supplement mesospheric data from an MST radar. The detection techniques required on the ST radar for delineating meteor echo returns are described

    This report contains the design, fabrication and accurate installation of ST3 shield, which would be installed at ST3 beam port of HANARO. At first, we designed and fabricated ST3 shield casemate composed of 14 blocks. We filled it with heavy concrete, lead ingot and polyethylene that mixed B 4 C powder and epoxy. The average filling density of total shield casemate was 4.7g/cm 3 . The developed ST3 shield was installed at the ST3 beam port and the accuracy of installation for each beam path and channel was evaluated. We found that the extraction of neutron beam to meet the requirement of neutron spectrometer is possible. Also, we developed ancillary equipment such as BGU, quick shutter and exterior shield door for the effective opening and closing of neutron beam. As a result of this study, it was found that neutron spectrometer such as neutron reflectometer and high intensity powder diffractomater can be installed at the ST3 beam port

  6. St. James marine terminal facility description

    Energy Technology Data Exchange (ETDEWEB)

    1993-10-01

    The US Department of Energy (DOE) currently owns and operates a marine terminal on the west bank of the Mississippi River at St. James, Louisiana. The St. James facility was constructed by the Department to provide marine services associated with the fill and drawdown of the Strategic Petroleum Reserve (SPR) crude oil storage facilities located at Bayou Choctaw and Weeks Island, Louisiana. Although strategic to the mission of the SPR in the event of a national emergency, the St. James terminal is situated such that it has a high potential to also serve the commercial industry`s needs for crude oil terminalling and storage. The St. James terminal is located approximately 45 miles west of New Orleans and 30 miles southeast of Baton Rouge, and approximately 160 miles upstream from the mouth of the Mississippi River. Construction of the St. James terminal was initiated in 1978 and was completed in 1980. Since then, the terminal has received and transferred over 125 million barrels of crude oil to the SPR sites for storage. For crude oil distribution, the St. James terminal was connected to the neighboring LOCAP terminal by a 0.1 mile 36-inch pipeline in 1981 and to the Capline terminal by a 0.5 mile 30-inch pipeline in 1988. The terminal also has a 30-inch pipeline connection to the Koch oil terminal which was used for initial fill purposes; however, this pipeline has been disconnected and is currently inactive. A complete description of the St. James terminal facilities, operational capabilities, operational certifications, and future Government requirements are presented in Sections 2, 3, 4, and 5 respectively.

  14. Three members of Medicago truncatula ST family are ubiquitous during development and modulated by nutritional status (MtST1) and dehydration (MtST2 and MtST3).

    2017-07-10

    ShooT specific/Specific Tissue (ST) belong to a protein family of unknown function characterized by the DUF2775 domain and produced in specific taxonomic plant families, mainly Fabaceae and Asteraceae, with the Medicago truncatula ST family being the largest. The putative roles proposed for this family are cell elongation, biotic interactions, abiotic stress and N reserve. The aim of this work was to go deeper into the role of three M. truncatula ST proteins, namely ST1, ST2 and ST3. Our starting hypothesis was that each member of the family could perform a specific role, and hence, each ST gene would be subjected to a different type of regulation. The search for cis-acting regulatory elements (CREs) in silico in pST1, pST2 and pST3 promoters showed prevalence of tissue/organ specific motifs, especially root- and seed-specific ones. Light, hormone, biotic and abiotic related motifs were also present. None of these pSTs showed the same combination of CREs, or presented the same activity pattern. In general, pST activity was associated with the vascular cylinder, mainly in roots. Promoter activation was highly specific and dissimilar during reproductive development. The ST1, ST2 and ST3 transcripts accumulated in most of the organs and developmental stages analysed - decreasing with age - and expression was higher in the roots than in the aerial parts and more abundant in light-grown plants. The effect of the different treatments on transcript accumulation indicated that ST1 behaved differently from ST2 and ST3, mainly in response to several hormones and dehydration treatments (NaCl or mannitol), upon which ST1 transcript levels decreased and ST2 and ST3 levels increased. Finally, the ST1 protein was located in the cell wall whereas ST2 and ST3 were present both in the cytoplasm and in the cell wall. The ST proteins studied are ubiquitous proteins that could perform distinct/complementary roles in plant biology as they are encoded by differentially regulated genes

    Sokolovsky, K. V.; Lebedev, A. A.

    2018-01-01

    Variability Search Toolkit (VaST) is a software package designed to find variable objects in a series of sky images. It can be run from a script or interactively using its graphical interface. VaST relies on source list matching as opposed to image subtraction. SExtractor is used to generate source lists and perform aperture or PSF-fitting photometry (with PSFEx). Variability indices that characterize scatter and smoothness of a lightcurve are computed for all objects. Candidate variables are identified as objects having high variability index values compared to other objects of similar brightness. The two distinguishing features of VaST are its ability to perform accurate aperture photometry of images obtained with non-linear detectors and handle complex image distortions. The software has been successfully applied to images obtained with telescopes ranging from 0.08 to 2.5 m in diameter equipped with a variety of detectors including CCD, CMOS, MIC and photographic plates. About 1800 variable stars have been discovered with VaST. It is used as a transient detection engine in the New Milky Way (NMW) nova patrol. The code is written in C and can be easily compiled on the majority of UNIX-like systems. VaST is free software available at http://scan.sai.msu.ru/vast/.

    Full Text Available Las técnicas emergentes de reproducción humana asistida, entre las que se encuentran la fecundación in vitro (FIV, suscitanuna serie de interrogantes científicas, éticas y sociales. En relación con el tema, Costa Rica ha generado controversia a nivelmundial, pues no ha legalizado dicha técnica de fecundación, ya que parte de argumentos jurídicos que, según la OPS y laCIDH, van en contra de los derechos humanos y reproductivos. Por la situación anterior es que a continuación se describenlas implicaciones éticas, legales, religiosas y socioeconómicas de la fecundación in vitro en la salud reproductiva de CostaRica. Se realizó una revisión y análisis documental. Se buscó información en las siguientes bases de datos: PubMed,Medline, Excelencia.net, EBSCO, Cochrane. Se encontraron referentes bibliográficos que enfocan los aspectos religiosos,legales, éticos y socioeconómicos, los cuales se analizaron a la luz de los derechos reproductivos y la implicación de estatécnica en la salud reproductiva de Costa Rica. La posición de los y las Enfermeras y el mundo científico, así como lasdecisiones tomadas por usuarios, deben estar acompañadas de una información amplia y correcta acerca de los métodos, delas oportunidades de embarazo y de los efectos secundarios que la FIV pueda acarrear, de modo que contemple tantocuidados preconcepcionales, prenatales y perinatales, de allí que el y la enfermera obstetra tiene un papel importante en laatención integral de la mujer durante el período prenatal, el parto y el postparto, así como de la asistencia inmediata yeficiente del recién nacido. Se concluye que la fecundación in vitro constituye una técnica médica que se utiliza en muchaspartes del mundo para tratar la esterilidad. Puede beneficiar a los usuarios individuales y a la sociedad en general, no sóloporque trata la esterilidad, sino porque también ofrece la posibilidad de evitar los defectos genéticos y mejora

    Full Text Available Resumen:En los últimos sesenta años han ocurrido cambios en el Humedal Nacional Térraba-Sierpe, Costa Rica. Los cambios en la geomorfología costera están asociados a la erosión o acreción de sedimentos, lo que ha favorecido la eliminación de sectores de bosque o a la formación de bancos de sedimentos que han sido colonizados por árboles de mangle. El estudio se realizó en los sectores Bocón, Brujo e isla Coco en Boca Zacate, Humedal Nacional Térraba-Sierpe, Costa Rica, entre 2008-2013, cuyo objetivo consiste en analizar el aporte de sedimentos y las implicaciones en la cobertura del bosque de mangle en el sector de Boca Zacate. Es este estudio se realizó un análisis multitemporal de la morfología litoral con fotografías aéreas e imágenes satelitales de 1948, 1960, 1974, 1978, 1984, 1992 y 2011. Y además, se cuantificó la tasa de sedimentación mensual (g/cm2/día en los canales de los estuarios, la composición granulométrica y la concentración de elementos químicos en los sedimentos (mgL-1 en época seca y lluviosa durante los años de estudio. Los resultados indican que Boca Zacate ha mantenido en los últimos 60 años una tendencia hacia la erosión, perdiendo un 10.6 % de su espacio emergido entre 1948 y 2011 y aproximadamente un 8.9 % de su cobertura forestal; también ha experimentado una acreción en la zona de la isla Coco, uniéndose al continente por este sector. La tasa de sedimentación cuantificada en los esteros presentó diferencias con respecto al sitio y a la época. La mayor cantidad se presentó en el estero el Brujo y la menor cantidad en el estero Camíbar. Con respecto a la granulo-metría, el tipo de sedimento dominante es la arena, seguido por la arcilla y en menor cantidad el limo en todos los sitios de estudio. La mayor distribución de los elementos químicos corresponde al magnesio, calcio, potasio; mientras que el manganeso, hierro, aluminio, fósforo, zinc y cobre se encontraron en menor

    Full Text Available En la actualidad, teorías provenientes del campo de la Psicología, especial- mente la Inteligencia Emocional y la Psicología Positiva, lideran los discursos y prácticas educativos. Sin embargo, dicho liderazgo ha sido objeto de esca- sos análisis desde el ámbito de conocimiento de la Teoría de la Educación, responsable, por su carácter normativo, de re ̄exionar acerca de los ®nes de la educación. Tomando como referencia los estudios provenientes de la Teoría de la Educación británica, el presente artículo aborda el análisis de las implicaciones de las teorías psicológicas para la educación. Para ello, en primer lugar se realiza una descripción de las bases de la Inteligencia Emo- cional y la Psicología Positiva, así como se muestran algunos ejemplos de su traducción educativa. En la segunda parte del artículo se aborda el análisis pedagógico, que se conceptualiza en términos de reducción en dos aspectos esenciales de la educación: el sujeto de la educación y la relación educativa. Se concluye que la reducción del sujeto de la educación es consecuencia de una concepción disminuida tanto de las posibilidades del sujeto, como de la experiencia emocional y de la propia racionalidad. Por su parte, la reducción de la relación educativa se produce a través de su conversión en una relación comunicativa, en la que el discurso sustituye a la acción. Se concluye que la educación tiene un carácter propio, diferente al de la psicología. Si bien la educación debe tomar en consideración el conocimiento aportado por la psicología, debe también mantener su carácter propio, basado en la con®anza de las posibilidades de los sujetos que se educan como principio y en la bús- queda del bien en su relación con el mundo y con los otros como ®nalidad. Así mismo, la relación educativa debe estar basada en la intencionalidad del educador y en la acción en lugar del discurso.

    Full Text Available Se argumenta a favor de una interpretación conductista de Wittgenstein, caracterizando esta postura como ?conductismo epistemológico? ?referido a juegos de lenguaje-, que no niega ?en el plano ontológico- la existencia de lo mental, que interpreta la conducta en sentido amplio y que tiene un marcado carácter social. En la base de este conductismo se encuentra la idea de que para establecer el juego de lenguaje de lo interno se precisa de criterios públicos, intersubjetivos. Se explora la posibilidad de elaborar una epistemología sociopsicológica naturalizada a partir del análisis lingüístico skinneriano y en consonancia con las observaciones de Wittgenstein. Se comentan las implicaciones del conductismo epistemológico para el lenguaje de los términos psicológicos.

    2001-01-01

    An analyse has been carried out in ST concerning the total costs for the division. Even though the target was the maintenance costs in ST, the global budget over has been analysed. This has been done since there is close relation between investments & consolidation and the required level for maintenance. The purpose of the analyse was to focus on maintenance cost in ST as a ratio of total maintenance costs over the replacement value of the equipment, and to make some comparisons with other industries and laboratories. Families of equipment have been defined and their corresponding ratios calculated. This first approach gives us some "quantitative" measurements. This analyse should be combined with performance indicators (more "qualitative" measurements) that are telling us how well we are performing. This will help us in defending our budget, make better priorities, and we will satisfy the requirements from our external auditors.

  11. The 21st Century as Whose Century?

    Directory of Open Access Journals (Sweden)

    David Scott

    2015-08-01

    Full Text Available Macro-analysis and East-West encounter are shown through consideration of objective yet subjective constructed concepts for the international system and international economy in the 21st century. Three paradigms are considered, namely the 21st century as the ‘Pacific Century’, as ‘China’s Century’ and as the ‘Asian Century’. Overlaps are shown between these three paradigms, as also developments in time, and gradually shift in geographical location. The ‘Pacific Century’, and its associated Rimspeak, was the paradigm emerging in the late 1970s, knitting together America’s West Coast and the Japanese economy. By the late 1980s this was already shifting to talk of the 21st century likely to be an ‘Asian Century’ model, mark-1, based on the Pacific Asia dynamism shown by the ‘Asian Tigers’ and Japan. However, the Asian financial crash of 1997-8, and the economic downturn in Japan, meant that such an ‘Asian Century’ seemed premature as the 21st century arrived. Instead, it was China’s economic growth that seemed most evident, and with it the concept of the 21st century as ‘China’s Century’. However, in turn that has already been modified during the first decade of the century by India’s arrival as a rapidly growing economy. Consequently the 21st century as ‘China’s Century’ and as ‘India’s Century’ has been combined into talk of an ‘Asian Century’, mark-2.

    Esperante Pereira, D

    2010-01-01

    This note describes the automatic operation sequences that the ECS implements in order to operate the ST detector in a safe and reliable way. First, the start-up sequences to set the detector in a well known state are described. In addition the possible ST detector states based on the status of the different detector elements will be defined. The states are of crucial interest for the safe operation of the detector when the LHC beam is ready. Besides, the ECS automatic actions taken in case of abnormal status of any of the detector elements are reported. Next, the operational alarm ranges and the error recovery mechanisms are mentioned.

  17. Unintended and unwanted pregnancy in St. Lucia.

    Science.gov (United States)

    Denton, A B; Chase, W M; Scott, K

    1994-09-01

    Among 200 mothers interviewed in St. Lucia, 82.5% described their pregnancy as unintended and 44% as unwanted; 80% of women having an intended pregnancy and 94.6% having an unintended pregnancy were unmarried and 18.5% were teenagers. Mothers of unintended pregnancies were significantly younger, were of significantly higher parity and had begun sexual relations at a significantly earlier age than mothers of intended pregnancies; and, unlike mothers of planned pregnancies, their desired interpregnancy interval was significantly longer than the actual interval. These results and the sporadic and ineffective use of contraception in St. Lucia emphasize the need for improvements in fertility regulation in that country.

    Neisseria meningitidis is an important causative agent of meningitis and/or sepsis with high morbidity and mortality. Baseline genome data on N. meningitidis, especially from developing countries such as India, are lacking. This study aimed to investigate the whole genome sequences of N. meningitidis isolates from a tertiary care centre in India. Whole-genome sequencing was performed using an Ion Torrent™ Personal Genome Machine™ (PGM) with 400-bp chemistry. Data were assembled de novo using SPAdes Genome Assembler v.5.0.0.0. Sequence annotation was performed through PATRIC, RAST and the NCBI PGAAP server. Downstream analysis of the isolates was performed using the Center for Genomic Epidemiology databases for antimicrobial resistance genes and sequence types. Virulence factors and CRISPR were analysed using the PubMLST database and CRISPRFinder, respectively. This study reports the whole genome shotgun sequences of eight N. meningitidis isolates from bloodstream infections. The genome data revealed two novel sequence types (ST12777 and ST12778), along with ST11, ST437 and ST6928. The virulence profile of the isolates matched their sequence types. All isolates were negative for plasmid-mediated resistance genes. To the best of our knowledge, this is the first report of ST11 and ST437 N. meningitidis isolates in India along with two novel sequence types (ST12777 and ST12778). These results indicate that the sequence types circulating in India are diverse and require continuous monitoring. Further studies strengthening the genome data on N. meningitidis are required to understand the prevalence, spread, exact resistance and virulence mechanisms along with serotypes.

  20. Isolation and characterization of styrene metabolism genes from styrene-assimilating soil bacteria Rhodococcus sp. ST-5 and ST-10.

    Science.gov (United States)

    Toda, Hiroshi; Itoh, Nobuya

    2012-01-01

    Styrene metabolism genes were isolated from styrene-assimilating bacteria Rhodococcus sp. ST-5 and ST-10. Strain ST-5 had a gene cluster containing four open reading frames which encoded styrene degradation enzymes. The genes showed high similarity to styABCD of Pseudomonas sp. Y2. On the other hand, strain ST-10 had only two genes which encoded styrene monooxygenase and flavin oxidoreductase (styAB). Escherichia coli transformants possessing the sty genes of strains ST-5 and ST-10 produced (S)-styrene oxide from styrene, indicating that these genes function as styrene degradation enzymes. Metabolite analysis by resting-cell reaction with gas chromatography-mass spectrometry revealed that strain ST-5 converts styrene to phenylacetaldehyde via styrene oxide by styrene oxide isomerase (styC) reaction. On the other hand, strain ST-10 lacked this enzyme, and thus accumulated styrene oxide as an intermediate. HPLC analysis showed that styrene oxide was spontaneously isomerized to phenylacetaldehyde by chemical reaction. The produced phenylacetaldehyde was converted to phenylacetic acid (PAA) in strain ST-10 as well as in strain ST-5. Furthermore, phenylacetic acid was converted to phenylacetyl-CoA by the catalysis of phenylacetate-CoA ligase in strains ST-5 and ST-10. This study proposes possible styrene metabolism pathways in Rhodococcus sp. strains ST-5 and ST-10. Copyright © 2011 The Society for Biotechnology, Japan. Published by Elsevier B.V.

  19. Epidemic potential of Escherichia coli ST131 and Klebsiella pneumoniae ST258: a systematic review and meta-analysis

    Dautzenberg, M J D; Haverkate, M R; Bonten, M J M; Bootsma, M C J

    2016-01-01

    Objectives Observational studies have suggested that Escherichia coli sequence type (ST) 131 and Klebsiella pneumoniae ST258 have hyperendemic properties. This would be obvious from continuously high incidence and/or prevalence of carriage or infection with these bacteria in specific patient populations. Hyperendemicity could result from increased transmissibility, longer duration of infectiousness, and/or higher pathogenic potential as compared with other lineages of the same species. The aim of our research is to quantitatively estimate these critical parameters for E. coli ST131 and K. pneumoniae ST258, in order to investigate whether E. coli ST131 and K. pneumoniae ST258 are truly hyperendemic clones. Primary outcome measures A systematic literature search was performed to assess the evidence of transmissibility, duration of infectiousness, and pathogenicity for E. coli ST131 and K. pneumoniae ST258. Meta-regression was performed to quantify these characteristics. Results The systematic literature search yielded 639 articles, of which 19 data sources provided information on transmissibility (E. coli ST131 n=9; K. pneumoniae ST258 n=10)), 2 on duration of infectiousness (E. coli ST131 n=2), and 324 on pathogenicity (E. coli ST131 n=285; K. pneumoniae ST258 n=39). Available data on duration of carriage and on transmissibility were insufficient for quantitative assessment. In multivariable meta-regression E. coli isolates causing infection were associated with ST131, compared to isolates only causing colonisation, suggesting that E. coli ST131 can be considered more pathogenic than non-ST131 isolates. Date of isolation, location and resistance mechanism also influenced the prevalence of ST131. E. coli ST131 was 3.2 (95% CI 2.0 to 5.0) times more pathogenic than non-ST131. For K. pneumoniae ST258 there were not enough data for meta-regression assessing the influence of colonisation versus infection on ST258 prevalence. Conclusions With the currently available data

    Ho Tan Tai Louis

    2001-03-01

    Full Text Available Detergents of the 21st century will depend on evolutions in household appliances, in substrates and in consumer needs. In addition, the environmental constraints, which become more and more stringent, will also play an important role, particularly in the formulations. Surfactants, which constitute one of the main raw materials in detergents, will have to be more environmentally friendly with increasing criteria of biodegradability and renewable materials. Builders (phosphates or zeolithes, heavy metal complexants (EDTA and bleaching agents (combination perborate/TAED are also expected to be replaced by biodegradable compounds, with better performances and lower costs. The real raw materials of the detergents of the 21st century will probably be enzymes (oxidase, hydrolase, peroxidase which present several advantages. At the same time, efforts will be made on biodegradable packaging through the use of micro-organisms able to degrade polymers. Finally, in terms of product forms, the concept of concentration might come back through the use of tablets.

    2015-01-01

    Full Text Available Gallbladder cancer (GBC is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

    The St. Lawrence Estuary, Eastern Canada, contains a very thick (>450 m) Quaternary sedimentary sequence. The results from recently conducted geophysical surveys in conjunction with piston coring indicate that these sediments were deposited under very high sedimentation rates, sometimes as high as {approx}30 m/ka during the last deglaciation. Results also reveal evidence of large submarine landslides during the Holocene, changes in sedimentation rates and the significant role of submarine canyons and channels to transfer sediments from the coast to the deeper marine environment. Finally, this paper highlights the presence of more than 1900 pockmarks on the seafloor of the St. Lawrence Estuary and discusses their possible origins: active hydrocarbon seeps in the Laurentian Channel and biogenic gas seepage on the northwestern shoulder of the Laurentian Channel.

The results from recently conducted geophysical surveys in conjunction with piston coring indicate that these sediments were deposited under very high sedimentation rates, sometimes as high as ∼30 m/ka during the last deglaciation. Results also reveal evidence of large submarine landslides during the Holocene, changes in sedimentation rates and the significant role of submarine canyons and channels to transfer sediments from the coast to the deeper marine environment. Finally, this paper highlights the presence of more than 1900 pockmarks on the seafloor of the St. Lawrence Estuary and discusses their possible origins: active hydrocarbon seeps in the Laurentian Channel and biogenic gas seepage on the northwestern shoulder of the Laurentian Channel.

  10. Baseline risk assessment for exposure to contaminants at the St. Louis Site, St. Louis, Missouri

    International Nuclear Information System (INIS)

    1993-11-01

    The St. Louis Site comprises three noncontiguous areas in and near St. Louis, Missouri: the St. Louis Downtown Site (SLDS), the St. Louis Airport Storage Site (SLAPS), and the Latty Avenue Properties. The main site of the Latty Avenue Properties includes the Hazelwood Interim Storage Site (HISS) and the Futura Coatings property, which are located at 9200 Latty Avenue. Contamination at the St. Louis Site is the result of uranium processing and disposal activities that took place from the 1940s through the 1970s. Uranium processing took place at the SLDS from 1942 through 1957. From the 1940s through the 1960s, SLAPS was used as a storage area for residues from the manufacturing operations at SLDS. The materials stored at SLAPS were bought by Continental Mining and Milling Company of Chicago, Illinois, in 1966, and moved to the HISS/Futura Coatings property at 9200 Latty Avenue. Vicinity properties became contaminated as a result of transport and movement of the contaminated material among SLDS, SLAPS, and the 9200 Latty Avenue property.

    Fort St. Vrain, on the system of Public Service Company of Colorado, is the only high-temperature gas-cooled power reactor in the United States. Four helium circulators are utilized in this plant to transfer heat from the reactor to the steam generators. These unique machines have a single stage axial flow helium compressor driven by a single stage steam turbine. A single stage water driven (pelton wheel) turbine is the back-up drive utilizing either feed water, condensate, or fire water as the driving fluid. Developmental testing of the circulators was accomplished prior to installation into Fort St. Vrain. A combined machine operating history of approximately 250,000 hours has shown these machines to be of conservative design and proven mechanical integrity. However, many problems have been encountered in operating the complex auxiliaries which are necessary for successful circulator and plant operation. It has been 15 years since initial installation of the circulators occurred at Fort St. Vrain. During this time, a number of significant issues had to be resolved dealing specifically with machine performance. These events include cavitation damage of the pelton wheels during the initial plant hot functional testing, cracks in the water turbine buckets and cervic coupling, static shutdown seal bellows failure, and, most recently, degradation of components within the steam drive assembly. Unreliable operation particularly with the circulator auxiliaries has been a focus of attention by Public Service Company of Colorado. Actions to replace or significantly modify the existing circulators and their auxiliaries are currently awaiting decisions concerning the long-term future of the Fort St. Vrain plant.

    Integrated scenario simulations are done for NSTX [National Spherical Torus Experiment] that address four primary milestones for developing advanced ST configurations: high β and high β N inductive discharges to study all aspects of ST physics in the high-beta regime; non-inductively sustained discharges for flattop times greater than the skin time to study the various current-drive techniques; non-inductively sustained discharges at high β for flattop times much greater than a skin time which provides the integrated advanced ST target for NSTX; and non-solenoidal start-up and plasma current ramp-up. The simulations done here use the Tokamak Simulation Code (TSC) and are based on a discharge 109070. TRANSP analysis of the discharge provided the thermal diffusivities for electrons and ions, the neutral-beam (NB) deposition profile, and other characteristics. CURRAY is used to calculate the High Harmonic Fast Wave (HHFW) heating depositions and current drive. GENRAY/CQL3D is used to establish the heating and CD [current drive] deposition profiles for electron Bernstein waves (EBW). Analysis of the ideal-MHD stability is done with JSOLVER, BALMSC, and PEST2. The simulations indicate that the integrated advanced ST plasma is reachable, obtaining stable plasmas with β ∼ 40% at β N 's of 7.7-9, I P = 1.0 MA, and B T = 0.35 T. The plasma is 100% non-inductive and has a flattop of 4 skin times. The resulting global energy confinement corresponds to a multiplier of H 98(y,2) 1.5.

    We construct explicit string theory models realizing the recently proposed “Stückelberg Portal” scenario, a framework for building Z{sup ′} mediation models without the need to introduce unwanted exotic matter charged under the Standard Model. This scenario can be viewed purely field-theoretically, although it is particularly well motivated from string theory. By analyzing carefully the Stückelberg couplings between the Abelian gauge bosons and the RR axions, we construct the first global intersecting brane models which extend the Standard Model with a genuine hidden sector, to which it is nonetheless connected via U(1) mass mixings. Utilizing the explicit models we construct, we discuss some broad phenomenological properties and experimental implications of this scenario such as Z−Z{sup ′} mixings, dark matter stability and relic density, and supersymmetry mediation. With an appropriate confining hidden sector, our setup also provides a minimal realization of the hidden valley scenario. We further explore the possibility of obtaining small Z{sup ′} masses from a large ensemble of U(1) bosons. Related to the Stückelberg portal are two mechanisms that connect the visible and the hidden sectors, namely mediation by non-perturbative operators and the hidden photon scenario, on which we briefly comment.

  17. Sediment Characterization in St. Alban's Bay, VT

    2017-12-01

    St. Alban's Bay within Lake Champlain is plagued with harmful algal blooms. With future intensification due to climate change, a multidisciplinary program (BREE-Basin Resilience to Extreme Events) was initiated in 2016. In order to assess the mobilization of harmful nutrients from sediment resuspension events and riverine input, 74 sediment samples were collected in a grid fashion throughout St. Alban's Bay. Sediments were deflocculated and analyzed using a LA920 Horiba laser scattering particle size distribution analyzer to define the frequency of sediment sizes from clay to sand. Gridded surfaces of mean sortable silt percentage, silt percentage, sand percentage, and clay percentage were used to represent the sediment distribution of the region. A plot of diameter versus frequency showed the bimodal nature of some of the sediments, with one peak at about 10 microns diameter (silt) and the second at about 525 microns diameter (sand). The data showed an extremely low percentage of clay relative to that of sand and silt. The highest frequencies of sortable silt, which represents the most easily mobilized particle size, are found in the deepest areas of the bay, suggesting that these regions are where dominant bottom flow occurs. The high occurrence of sortable silt in the St. Alban's Bay does suggest that sediment mobilization, and therefore nutrient mobilization has the potential to occur. These data combined with high-resolution multibeam and hydrodynamic data will allow for future models of water flow and remobilization studies in the future.

  18. Carl Størmer Auroral Pioneer

    CERN Document Server

    Egeland, Alv

    2013-01-01

    This biography summarizes the seminal contributions to auroral and space science of Carl Størmer (1874 - 1957). He was the first to develop precise photographic methods to calculate heights and morphologies of diverse auroral forms during four solar cycles. Størmer independently devised numerical techniques to determine the trajectories of high-energy charged particles allowed and forbidden in the Earth’s magnetic field. His theoretical analyses explained cosmic ray access to the upper atmosphere, 20 years before they were identified by other scientists. Størmer’s crowning achievement, “The Polar Aurora,” published when he was 81 years old, stands to this day as a regularly cited guide in graduate-level courses on space physics.   The authors present the life of this prodigious scientist in relation to the cultural life of early 20th century in Norway and to the development of the space sciences in the post-Sputnik era.

  19. Stereospecificity (ST) of the microsomal ethanol oxidizing system (MEOS)

    1987-01-01

    The ST of MEOS for the ethanol 1R hydrogen has been variously reported as absolute, partial or absent, with free radical involvement postulated in the latter case. To determine both the ST of MEOS and the participation of free radicals in the reaction, they investigated MEOS ST using 1R[1- 3 H] ethanol as substrate. ST is expressed as the fraction of 3 H labeling in acetaldehyde formed, relative to that in ethanol, and ranges from 0.5 to 0. Partial ST was observed using liver microsomes from both rats and hamsters; it significantly decreased after ethanol feeding. 0.1 mM desferrioxamine (dfx) did not increase ST in any of these microsomal preparations while ferric EDTA decreased it, suggesting that ethanol treatment induces a cytochrome P-450 with lower ST rather than increasing free radical involvement. This is supported by a virtual absence of ST observed in a reconstituted system containing purified hamster P-450/sub ALC/, a liver cytochrome P-450 isozyme induced in hamsters by ethanol treatment. Their results indicate that, unlike other enzymes that oxidize ethanol, MEOS has only partial ST. Thus, ST alone cannot be used as an index of free radical involvement but, when evaluated with the response of ST to dfx, it indicated that MEOS is unlikely to involve free radical attack on ethanol in solution

    Full Text Available Although equity-based arrangements, particularly Joint Ventures, are more effective than the contractual ones when trying to have access to knowledge needed for innovation, research on the factors on how to successfully achieve the development and implementation of this strategy is scarce and scattered. From the Upper Echelon Theory, the objective of this work is to develop a review and integration of the literature about shared control Joint Ventures, top management teams and innovation and to propose a framework of relationships. The role and implications of the top management team in carrying out a Joint Venture created to innovate is analyzed in this article, having as a conclusion that the diversity of the TMT (top management team can positively or negatively influence the results of such innovation. The directive nature of their work in relation to the parent companies may hinder the achievement of the objectives for which they were created. Other factors that may help correct the negative implications about innovation, created by the team composition and the characteristics of their work, are also considered.Aunque los acuerdos basados en capital, especialmente las Joint Ventures, son más efectivos que los contractuales a la hora de acceder al conocimiento necesario para la innovación, la investigación sobre los factores favorables al éxito en el desarrollo y consecución de esta estrategia es escasa y dispersa.

    Exercise-induced ST elevation in patients with previous myocardial infarction (MI) has been recognized to be related to left ventricular (LV) asynergy, however it is also recognized that myocardial ischemia can induce ST elevation. In this study, factors which determine the extent of ST elevation, with special reference to myocardial ischemia, was re-evaluated using quantitative analysis of stress myocardial scintigraphy (S-SG). Among 65 patients with previous anterior myocardial infarction and documented single vessel disease of left anterior descending artery (LAD), 19 patients who had exercise-induced ST elevation (ΔST ≥ 2.0 mm) had more abnormal Q waves (p < 0.01), lower LV ejection fraction (EF) (p < 0.01), more severe LV asynergy (p < 0.05) and less incidence of post-MI angina pectoris (AP) (p < 0.01), compared to those with ΔST < 2.0 mm, indicating that ST elevation is primarily related to LV asynergy. Correlation studies among clinical, angiographic and scintigraphic parameters show that ΔST was significantly related to a size of MI represented by Tl score or relative defect Tl activity and number of abnormal Q waves (No.Q), the magnitude of work load expressed by changes in double product (ΔDP) and intervals between the onset and exercise test, as well as myocardial ischemia expressed by the extent of redistribution (%RD) in S-SG. Among 23 patients with post-MI AP, ΔST significantly correlated with %RD (r = 0.47), indicating that myocardial ischemia can be a mechanism of exercise-induced ST elevation in patients with previous MI. Furtheremore, among those with ST elevation, concave-type ST elevation was more related to myocardial ischemia compared to convex-type ST elevation as expressed by the incidence of post-MI AP and/or significant redistribution.

    Full Text Available Si comparamos el sistema económico, administrativo y financiero de la Iglesia y de la Hacienda Pública castellana en la Edad Moderna observamos grandes similitudes. Nada de extrañar si consideramos que la Iglesia fiscalizaba a los fieles y la Monarquía a los ciudadanos. La red recaudatoria clerical llegaba hasta las parroquias como la Real a todos los rincones del Estado y confluía en centros de recaudación y de responsabilidad, cuya actividad controlaban los contadores eclesiásticos y los públicos, respectivamente. La contabilidad eclesiástica era administrativa y presupuestaria como la del Estado. En este contexto regía el principio de afectación, donde los gastos se financian con ingresos específicos a ellos afectados que deberán especificarse y permitir su seguimiento. Un principio contrario al principio de no afectación que rige actualmente en la Administración Pública.    En este trabajo demostraremos cómo la afectación de los gastos a los ingresos eclesiásticos es un principio relacionado con la destinación de los bienes presente en la doctrina de la Iglesia. Asimismo, probaremos que la aplicación de este principio tuvo implicaciones en la organización administrativa, en el sistema contable y en los dispositivos de control.

    ST-162 and ST-168 are small-molecule bifunctional inhibitors of MEK and PI3K signaling pathways that are being developed as novel antitumor agents. Previous small-molecule and biologic MEK inhibitors demonstrated ocular toxicity events that were dose limiting in clinical studies. We evaluated in vitro and in vivo ocular toxicity profiles of ST-162 and ST-168. Photoreceptor cell line 661W and adult retinal pigment epithelium cell line ARPE-19 were treated with increasing concentrations of bifunctional inhibitors. Western blots, cell viability, and caspase activity assays were performed to evaluate MEK and PI3K inhibition and dose-dependent in vitro toxicity, and compared with monotherapy. In vivo toxicity profile was assessed by intravitreal injection of ST-162 and ST-168 in Dutch-Belted rabbits, followed by ocular examination and histological analysis of enucleated eyes. Retinal cell lines treated with ST-162 or ST-168 exhibited dose-dependent inhibition of MEK and PI3K signaling. Compared with inhibition by monotherapies and their combinations, bifunctional inhibitors demonstrated reduced cell death and caspase activity. In vivo, both bifunctional inhibitors exhibited a more favorable toxicity profile when compared with MEK inhibitor PD0325901. Novel MEK and PI3K bifunctional inhibitors ST-162 and ST-168 demonstrate favorable in vitro and in vivo ocular toxicity profiles, supporting their further development as potential therapeutic agents targeting multiple aggressive tumors.

    Wilhelmsson, M

    2000-01-01

    The CNGS project concerns the construction of a neutrino beam facility (CNGS = CERN Neutrino beam to Gran Sasso). A 450 GeV proton beam will be extracted from the SPS accelerator. This proton beam will hit a target a few hundred metres downstream from the extraction point (BA4). In the debris of the proton beam we will find pions which continue down a 1000 m, evacuated tunnel and a fraction of which decay into a neutrino beam. After this decay tunnel (1.1 km), a 'hadron stop' will separate the neutrinos, after which they will resume their journey down to a detector pit, outside Rome (Gran Sasso). The CERN facility has a total length of approximately 3 km. The ST division has an important share in the construction work, both of the above-mentioned tunnels as well as of all other infrastructure services, and this work concerns most of the groups in the division. This report will outline the technical design of the facility and explain how we, in the ST division, are involved in the project. The CERN council app...

    During the last few decades scientists have been able to test the bases of the physics paradigms, where the quantum mechanics has to match the cosmological scales. Between the extremes of this scenario, biological phenomena and their complexity take place, challenging the laws we observe in the atomic and sub-atomic world. In order to explore the details of this world, new huge experimental facilities are under construction. These projects involve people coming from several countries and give physicists the opportunity to work together with chemists, biologists and other scientists. The Roman Young Researchers Meeting is a conference, organised by Ph. D. students and young postdocs connected to the Roman area. It is aimed primarily at graduate students and post-docs, working in physics. The 1st conference has been held on the 21st of July 2009 at the University of Roma Tor Vergata. It was organised in three sessions, devoted to Astrophysics and Cosmology, Soft and Condensed Matter Physics and Theoretical and ...

    Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

    Atmospheric pollutants may cause damage to monuments and historical buildings. Besides air contaminants, soluble salts are also responsible for stone deterioration and decay in outdoor and indoor monuments. The problem of how to conserve works of arts thus requires a deep knowledge of contaminants' concentration and distribution inside buildings. In this work, water-soluble ions inside St. Mark's Basilica in Venice were studied, with the aim of understanding their principal source and distribution inside the building. With the aid of Fourier transform infrared spectroscopy and scanning electron microscopy analysis, the interaction between ions and surface's material was also investigated. Ion chromatographic analysis of depositions highlighted a large amount of "deteriorating agents" such as sulphates and chlorides. A possible source in the innermost area of the basilica has been found for formates and nitrates. On the contrary, a decrease of chloride, from the entrance to the innermost area, has been found, which indicates that the source is outside the building. It is emphasized that different contaminants behave differently on different material, and the effect of pollution inside churches and monuments is not easy to predict. Wood and brick seem to react differently than stone and mortar to the damaging action of salts and pollutants. The present work should be considered a useful tool for the future preservation of St. Mark's Basilica in Venice.

    Fort St. Vrain is a high temperature gas cooled reactor. It has been shut down as a result of financial and technical difficulties. Fort St. Vrain has been planning for defueling and decommissioning for at least three years. The preliminary decommissioning plan, in accordance with the NRC's final rule, has been submitted and is being reviewed by the NRC. The basis of the preliminary decommissioning plan has been SAFSTOR. Public Service Company, who is the owner and operator of FSV, is scheduled to submit a proposed decommissioning plan to the NRC in the fourth quarter of 1990. PSC has gone out for bid on the decontamination and dismantlement of FSV. This paper includes the defueling schedule, the independent spent fuel storage installation status, the probability of shipping fuel to DOE, the status of the preliminary decommissioning plan submittal, the issuance of a possession only license and what are the results of obtaining this license amendment, preliminary decommissioning activities allowed prior to the approval of a proposed decommissioning plan, the preparation of a proposed decommissioning plan and the status of our decision to proceed with SAFSTOR or DECON as identified in the NRC's final decommissioning rule

    2003-01-01

    During the next three years, the ST/CV group will be deeply involved in the installation works for the LHC project. During this period the need for maintenance activity will decrease. The minimum level will be reached during the “long shutdown” of the PS and SPS machines in 2005. The budget for the maintenance will decrease accordingly, thus the CV group had to review its maintenance strategy. The new contract, which started on January 1st 2003, has been defined to cope with these workload variations during the next years and to guarantee the minimum maintenance activity on the existing equipment. A lump-sum contract based on a win-win strategy has been discarded. The contractor no longer has to guarantee the performance of the CERN cooling and ventilation systems. A new price list strategy based on performance indicators and penalties has been chosen. The contractor now has to guarantee the performance of every maintenance operation demanded by CERN. This modification obliged the Operation section of the...

  7. Electrocardiogram ST-Segment Morphology Delineation Method Using Orthogonal Transformations.

    Directory of Open Access Journals (Sweden)

    Miha Amon

    Full Text Available Differentiation between ischaemic and non-ischaemic transient ST segment events of long term ambulatory electrocardiograms is a persisting weakness in present ischaemia detection systems. Traditional ST segment level measuring is not a sufficiently precise technique due to the single point of measurement and severe noise which is often present. We developed a robust noise resistant orthogonal-transformation based delineation method, which allows tracing the shape of transient ST segment morphology changes from the entire ST segment in terms of diagnostic and morphologic feature-vector time series, and also allows further analysis. For these purposes, we developed a new Legendre Polynomials based Transformation (LPT of ST segment. Its basis functions have similar shapes to typical transient changes of ST segment morphology categories during myocardial ischaemia (level, slope and scooping, thus providing direct insight into the types of time domain morphology changes through the LPT feature-vector space. We also generated new Karhunen and Lo ève Transformation (KLT ST segment basis functions using a robust covariance matrix constructed from the ST segment pattern vectors derived from the Long Term ST Database (LTST DB. As for the delineation of significant transient ischaemic and non-ischaemic ST segment episodes, we present a study on the representation of transient ST segment morphology categories, and an evaluation study on the classification power of the KLT- and LPT-based feature vectors to classify between ischaemic and non-ischaemic ST segment episodes of the LTST DB. Classification accuracy using the KLT and LPT feature vectors was 90% and 82%, respectively, when using the k-Nearest Neighbors (k = 3 classifier and 10-fold cross-validation. New sets of feature-vector time series for both transformations were derived for the records of the LTST DB which is freely available on the PhysioNet website and were contributed to the LTST DB.

    1987-01-01

    Both NCC-ST-439 and NCC-ST-433 are monoclonal antibodies raised against human gastric cancer (St-4) xenografts in nude mice. Imaging and localization experiments were performed by injecting I-125 labeled antibodies into nude mice bearing CO-4 (colon carcinoma) and H-111 (gastric carcinoma). There was uptake of NCC-ST-439 (polymer) into the CO-4, though it was not clearly visualized until 5 days post injection. By injecting NCC-ST-439 (monomer), CO-4 was better seen at day 3, while average accumulation into the tumors decreased compared with NCC-ST-439 (polymer). High radioactivities were observed in the liver and spleen, which was probably due to the immunocomplex with the antigen in the blood. NCC-ST-433 was selectively accumulated into the H-111 with tumor to blood ratio 7.8 at day 7, without significant uptake into the liver and spleen. Significant correlation was also found between the tumor uptake level of NCC-ST-433 and size of tumors. Excellent images of H-111 were obtained 3 days after the injection. NCC-ST-433 holds promise for the radioimmunodetection of gastric cancers. (author)

  12. Nuclear Power in the 21st Century

    2013-01-01

    The International Atomic Energy Agency helps its Member States to use nuclear technology for a broad range of peaceful purposes, one of the most important of which is generating electricity. The accident at the Fukushima Daiichi nuclear power plant in Japan in March 2011 caused anxiety about nuclear safety throughout the world and raised questions about the future of nuclear power. Two years on, it is clear that the use of nuclear power will continue to grow in the coming decades, although growth will be slower than was anticipated before the accident. Many countries with existing nuclear power programmes plan to expand them. Many new countries, both developed and developing, plan to introduce nuclear power. The factors contributing to this growing interest include increasing global demand for energy, as well as concerns about climate change, volatile fossil fuel prices, and security of energy supply. It will be difficult for the world to achieve the twin goals of ensuring sustainable energy supplies and curbing greenhouse gases without nuclear power. The IAEA helps countries that opt for nuclear power to use it safely and securely. Countries that have decided to phase out nuclear power will have to deal with issues such as plant decommissioning, remediation, and waste management for decades to come. The IAEA also assists in these areas. I am grateful to the Russian Federation for hosting the 2013 International Ministerial Conference on Nuclear Power in the 21st Century in St Petersburg in June. This timely conference provides a valuable opportunity to take stock of nuclear power in the wake of the Fukushima Daiichi accident. A high level of public confidence in the safety of nuclear power is essential for the future of the sector. Much valuable work has been done in the past two years to improve safety. But much remains to be done. It is vitally important that the momentum is maintained and that everything is done to ensure that nuclear power is as safe as humanly

    Emphasis in the report is placed on how to cope with the stringent situation of energy resources in Japan when the energy demands are rising with the advance of economies. For the future, countermeasures must be taken in time and on firm basis. The characteristics of respective energy resources are clarified, and on this basis, review is made on the energy supplies up to the beginning of the 21st century. In the above connection, the following measures are taken up: promotion of energy saving, stable supply of petroleum, development and utilization of substitute energies, development of technologies for new energies, enhancement in the location of power stations, and securing of the necessary funds. In conclusion, it points out the need for further efforts on overall energy measures and the need for full co-ordination of the energy policy with the social situation. (Mori, K.)

    Our primary agenda for the 21st Century is the reinvention of America. We must reinvent democracy, capitalism, entrepreneurism, and community. Indeed, we must recreate all of our major social institutions. This includes health care. A design for a new society requires a new design for health care. In fact, health care enjoys a special privilege in this regard. It is the gateway to total societal redesign. Health is the common denominator in any society. If you loose your health you cannot work, you cannot play, you cannot study; and, if you lose it sufficiently, you cannot even pray. Health and well-being create the foundation for all other constructive human endeavors. Therefore, the design of healthy communities is the necessary first step in the redesign of total human habitats. This massive redesign effort will take a century. However, it will be launched in the next few years.

    Fort St. Vrain Nuclear Generating Station (FSV) is one of the first commercial reactors to be decommissioned under NRC's decommissioning rule. The defueling and decommissioning of this 330 MWe High Temperature Gas Cooled Reactor (HTGR) has involved many challenges for Public Service Company of Colorado (PSC) including defueling to an Independent Spent Fuel Storage Installation (ISFSI), establishing decommissioning funding, obtaining regulatory approvals, arranging for waste disposal, and managing a large fixed price decommissioning contract. In 1990, a team comprised of the Westinghouse Corporation and Morrison Knudsen Corporation, with the Scientific Ecology Group as a major subcontractor, was contracted by PSC to perform the decommissioning under a fixed price contract. Physical work activities began in August 1992. Currently, physical dismantlement activities are about 45% complete, the project is on schedule, and is within budget

    The strength of the 44.45 mm (1.75 in.) diameter Fort St. Vrain (FSV) reflector dowel for loads directed radially inward toward the center of the element was measured. For a statically applied load, the strength exceeded 5783 N (1300 lb) in direct shear. This strength remained after load cycling 100 times to 4448 N (1000 lb), 10 times to 4893 N (1100 lb), 10 times to 5338 N (1200 lb), and two times to 5783 N (1300 lb). Typically, the deflection to ultimate failure was approximately 1.0 mm (0.04 in.). At about 3316 N (750 lb) and 0.20 mm (0.008 in.) deflection, one of the webs between the dowel and a coolant hole cracked, apparently redistributing the load. No further failure occurred up to the ultimate load of 5783+ N (1300+ lb)

    On the leading edge in ''high-tech'' medicine, radiology is experiencing several revolutions simultaneously that promise an exciting future. New imaging methods and digital technologies not only offer novel ways to view tissues but also provide opportunities for quantitative evaluation of function and even permit determination of metabolic status. New approaches to technology assessment are being explored that alter the ways in which equipment and procedures are introduced into clinical medicine. With the plethora of radiology services available, the radiologist must serve as a consultant in the triage of patients in radiology and the dissemination of information from radiology. For similar reasons, training in diagnostic radiology may eventually accommodate to the concept of specialization along organ-system lines. Without question, radiology is destined for an exciting period as it moves into the 21st century

    To examine instructors' and students' perspectives on motivation in the classroom and clinical environments and to explore instructional strategies educators can use to motivate college students in the 21st century. Articles selected for this review were from peer-reviewed journals and scholarly sources that emphasized student and educator perspectives on motivation and instructional strategies to increase student motivation. Understanding how college students are motivated can help educators engage students in lessons and activities, ultimately improving the students' academic performance. Students exhibit increased motivation in classes when educators have high expectations, conduct an open-atmosphere classroom, and use multidimensional teaching strategies. Instructional styles such as connecting with students, creating an interactive classroom, and guiding and reminding students improved student motivation. Radiologic science educators must be mindful of how college students are motivated and use various instructional strategies to increase students' motivation in the classroom and clinical setting. ©2016 American Society of Radiologic Technologists.

    Leaders know how to achieve goals and inspire people along the way. While the terms and definitions may change with the times, it is important to understand the skills and abilities needed to lead in the 21st century. Most effective leaders have one element in common, and that is they are able to keep their teams engaged. If team members are not engaged, they may very well leave the organization. With four generations in the workplace, leaders must adapt and modify their leadership style in order to maintain employee engagement. The ability to lead effectively is based on a number of skills, including communication, motivation, vision, modeling, demonstrating empathy, confidence, persistence, and integrity.

    The Fort St. Vrain program has progressed through construction, preoperational testing, fuel loading, initial criticality, and operational testing at power levels up to 2 percent related power. To date, all tests necessary before the rise to full power have been completed, and the rise-to-power program is expected to be resumed again in late 1975. Major plant systems, including the prestressed concrete reactor vessel and circulators, have demonstrated adequate performance. Extensive tests on the reactor core at zero power and up to 2 percent power have demonstrated the accuracy in the design predictions of such core characteristics as critical rod position, control system worths, neutron flux distributions, and temperature coefficients. Gaseous fission product release measurements to date have confirmed the extensive analytical estimates. 6 references

El cruce que planteamos tiene como protagonistas al artista Robert Smithson y a los arquitectos Adam Caruso y Peter St John. Estos últimos hacen mención del trabajo del artista norteamericano para explicar su proyecto de remodelación de Stortorget, la plaza de la catedral en el centro de Kalmar, Suecia. A partir de aquí, comenzamos una exploración del trabajo y las preocupaciones de ambos que nos permite dibujar convergencias y sintonías procesuales por encima de las diferencias temáticas, ideológicas y estilísticas. Al disponer en paralelo la obra de Smithson y Caruso St John descubrimos vibraciones y resonancias que muestran una interacción productiva de sus preocupaciones. La materia se convierte en sus propuestas en un objeto activo y sensible, un depósito energético con el que operar. El traslado de piedras en Stortorget convoca la memoria de la ciudad del mismo modo que el basalto y la sal del Spiral Jetty, erosionados por el tiempo, nos hablan de procesos abiertos. El tiempo y la memoria pasan a ser soportes estratégicos con los que construyen sus miradas. Los objetos se disuelven en las relaciones que establecen con su entorno produciendo equilibrios frágiles e instantáneos. De esta manera el artículo pretende generar un vórtice de reflexión, una espiral en cuyo recorrido se manifiesten las tensiones parciales del cruce propuesto, sus fijezas momentáneas.

  9. Operational experience at Fort St. Vrain

    The Fort St. Vrain (FSV) station, a 330-MW(e) single reheat steam cycle powered by a high-temperature gas-cooled reactor (HTGR), is the first HTGR to enter commercial operation. Designed and built by General Atomic Company (GA), the plant is owned and operated by Public Service Company of Colorado (PSC). Many unique design features have been incorporated into this reactor system, including high-pressure helium as the primary system coolant, a graphite-moderated prismatic block core design, fission-product-containing carbide coatings on both fissile and fertile fuel particles, steam-driven helium circulators turning on water bearings, and once-through steam generators. All of these systems are contained in a prestressed concrete reactor vessel (PCRV). Extensive testing has been conducted during the rise to power following first criticality early in 1974 to verify system design performance. During this period, the plant has operated at power levels up to 70% and produced over one billion kilowatt hours of electricity. In 1979, the first refueling was conducted in conjunction with an extensive in-core inspection, the addition of in-core instrumentation, and a planned removal of a circulator for inspection. Later in the year, a scheduled shutdown was undertaken for surveillance tests, insertion of core region constraint devices (RCDs), and other maintenance. Fort St. Vrain has encountered problems of the type that would be expected in a first-of-a-kind system. The plant is currently restricted to 70% of design power by the Nuclear Regulatory Commission (NRC) pending resolution of the core region gas outlet temperature fluctuation problem. Even so, the basic performance of the HTGR concept and all of the unique design features have been successfully demonstrated. The system has been characterized by low personnel radiation exposures, operational flexibility, and long time afforded for status evaluation and response. (author)

  15. Escherichia coli ST131, an Intriguing Clonal Group

    2014-01-01

    SUMMARY In 2008, a previously unknown Escherichia coli clonal group, sequence type 131 (ST131), was identified on three continents. Today, ST131 is the predominant E. coli lineage among extraintestinal pathogenic E. coli (ExPEC) isolates worldwide. Retrospective studies have suggested that it may originally have risen to prominence as early as 2003. Unlike other classical group B2 ExPEC isolates, ST131 isolates are commonly reported to produce extended-spectrum β-lactamases, such as CTX-M-15, and almost all are resistant to fluoroquinolones. Moreover, ST131 E. coli isolates are considered to be truly pathogenic, due to the spectrum of infections they cause in both community and hospital settings and the large number of virulence-associated genes they contain. ST131 isolates therefore seem to contradict the widely held view that high levels of antimicrobial resistance are necessarily associated with a fitness cost leading to a decrease in pathogenesis. Six years after the first description of E. coli ST131, this review outlines the principal traits of ST131 clonal group isolates, based on the growing body of published data, and highlights what is currently known and what we need to find out to provide public health authorities with better information to help combat ST131.

  8. ST2 IN REJECTION OF THE TRANSPLANTED HEART

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available This review summarizes the current literature devoted to the analysis of prognostic role of ST2 biomarker in rejection of the transplanted heart. ST2 is one of the most promising diagnostic markers of the development and severity of heart failure as well as the mortality risk in patients with cardiovascular diseases. ST2 is expressed in cardiomyocytes in response to a variety of pathological processes and mechanical damage to the heart, which allows diagnosing cardiovascular diseases before clinical manifestations. Presumably, measuring the level of ST2 in heart transplant may have diagnostic and prognostic value in the assessment of graft and risk of rejection. Currently, accumulated clinical data on the role of given biomarker in heart transplantation are not enough, and further research on the relation of ST2 levels with different clinical and laboratory parameters in heart recipients is necessary.

A total of 10 clinical samples were collected from 5 patients who were involved in the outbreak. Bacterial identification and antibiotic sensitivity tests were performed by the VITEK-2 COMPACT automated system. MICs of tigecycline for clinical isolates were determined using broth microdilution. The clonal relatedness of A. baumannii clinical isolates in our local settings was determinated by pulsed-field gel electrophoresis (PFGE and multilocus sequence typing (MLST. A total of 7 A. baumannii strains were isolated and all were MDR strains; two of them were carbapenem-nonsusceptible strains. blaOXA-23 was the only acquired carbapenemase gene in the isolates. The isolates belonged to a single clonal pulsotype determined by PFGE and two sequences types (STs determined by MLST. The isolates belonged to the globally disseminated clonal complex 92, among which ST195 and ST208 were the most common sequence types (71.43% and 28.57%. The outbreak was successfully controlled by stringent infection control measures, especially improving the hand hygiene compliance and enhancing antimicrobial stewardship. In conclusion, this is the first description of an outbreak caused mainly by A. baumannii of ST208 in China. Infection control measures should be strengthened when infection outbreaks in hospital.

    The environmental monitoring program, which began in 1984, continued during 1989 at the St. Louis Airport Site (SLAPS) in St. Louis County, Missouri. SLAPS and its vicinity properties, including ditches north and south of the site, were designated for cleanup as part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), a United States Department of Energy (DOE) program to identify and decontaminate or otherwise control sites where residual radioactive material remains from the early years of the nation's atomic energy program. The monitoring program at SLAPS measures radon concentrations in air; external gamma dose rates; and uranium, thorium, and radium concentrations in surface water, groundwater, and sediment. Additionally, several nonradiological parameters are measured in groundwater. To assess the potential effect of SLAPS on public health, the potential radiation dose was estimated for a hypothetical maximally exposed individual. This report presents the findings of the environmental monitoring program conducted at the St. Louis Airport Site (SLAPS) during calendar year 1989. 19 refs., 13 figs., 14 tabs.

    Cytosolic sulfotransferases (SULTs) constitute a family of Phase II detoxification enzymes that are involved in the protection against potentially harmful xenobiotics as well as the regulation and homeostasis of endogenous compounds. Compared with humans and rodents, the zebrafish serves as an excellent model for studying the role of SULTs in the detoxification of environmental pollutants including environmental estrogens. By searching the expressed sequence tag database, two zebrafish cDNAs encoding putative SULTs were identified. Sequence analysis indicated that these two putative zebrafish SULTs belong to the SULT1 gene family. The recombinant form of these two novel zebrafish SULTs, designated SULT1 ST7 and SULT1 ST8, were expressed using the pGEX-2TK glutathione S-transferase (GST) gene fusion system and purified from transformed BL21 (DE3) cells. Purified GST-fusion protein form of SULT1 ST7 and SULT1 ST8 exhibited strong sulfating activities toward environmental estrogens, particularly hydroxylated polychlorinated biphenyls (PCBs), among various endogenous and xenobiotic compounds tested as substrates. pH-dependence experiments showed that SULT1 ST7 and SULT1 ST8 displayed pH optima at 6.5 and 8.0, respectively. Kinetic parameters of the two enzymes in catalyzing the sulfation of catechin and chlorogenic acid as well as 3-chloro-4-biphenylol were determined. Developmental expression experiments revealed distinct patterns of expression of SULT1 ST7 and SULT1 ST8 during embryonic development and throughout the larval stage onto maturity.

    Full Text Available Salmonella Typhimurium sequence type (ST 313 produces septicemia in infants in sub-Saharan Africa. Although there are known genetic and phenotypic differences between ST313 strains and gastroenteritis-associated ST19 strains, conflicting data about the in vivo virulence of ST313 strains have been reported. To resolve these differences, we tested clinical Salmonella Typhimurium ST313 and ST19 strains in murine and rhesus macaque infection models. The 50% lethal dose (LD50 was determined for three Salmonella Typhimurium ST19 and ST313 strains in mice. For dissemination studies, bacterial burden in organs was determined at various time-points post-challenge. Indian rhesus macaques were infected with one ST19 and one ST313 strain. Animals were monitored for clinical signs and bacterial burden and pathology were determined. The LD50 values for ST19 and ST313 infected mice were not significantly different. However, ST313-infected BALB/c mice had significantly higher bacterial numbers in blood at 24 h than ST19-infected mice. ST19-infected rhesus macaques exhibited moderate-to-severe diarrhea while ST313-infected monkeys showed no-to-mild diarrhea. ST19-infected monkeys had higher bacterial burden and increased inflammation in tissues. Our data suggest that Salmonella Typhimurium ST313 invasiveness may be investigated using mice. The non-human primate results are consistent with clinical data, suggesting that ST313 strains do not cause diarrhea.

    Environmental issues in the 21st century D.B. Chambers SENES Consultants Limited, Richmond Hill, Ontario, Canada Abstract. This paper provides an overview of some of the environmental challenges facing the uranium production industry in the 21st century. For many years, the linear, non-threshold (LNT) model has been regarded as a prudent hypothesis for radiation protection purposes. This paradigm has been challenged at the same time for both underestimating and overestimating the risks from ionizing radiation. The reality is that the ability of conventional epidemiology to distinguish small risks will always be limited by statistical power at low doses. In the future, there will be increased emphasis on better understanding the effects of ionizing radiation at the cellular (and sub cellular) level. The concept of 'controllable dose' has been proposed as an alternative to the International Commission on Radiological Protection's (ICRP) current approach to dose limitation. The concept is that if the most exposed individual is protected, then society as a whole is protected. A hazard ranking scale based on comparisons to natural background levels of radiation has been proposed. Adoption of a concept such as 'controllable dose' would require a parallel re-evaluation of the concepts and application of collective dose and ALARA optimization. The protection of non-human biota is an issue of considerable interest in many countries. The science in this area is rapidly evolving, as are discussions of a more philosophical nature. For example, should the focus of environmental risk assessment be the sustainability of the population or should the focus be to limit effects on a single member of the population? The future of environmental risk assessment should be of great interest to the uranium production industry. A systematic approach to risk assessment addressing the full scope of potential hazards -- environmental, human health, engineering, financial and others -- will be

    Every economic institution finds itself caught on the horns of a dilemma: Competing sets of values strike a conflict between social good and economic wealth, regardless of whether organizations articulate it. The struggle in U.S. health care, however, is both more acute and poignant. On the one hand, ethical and cultural values require societal commitments to the well-being of the individual. Who among us would want to refuse help to someone sick or injured? On the other hand, market forces require an economic accounting of health care. Social trends emphasize a mission to provide care for all, while managed care promotes the industry's fidelity to a balanced ledger. U.S. health care is thus defined by paradox. The nation spends more than $1.3 trillion annually on health care--a national line-item larger than the economies of all other nations except two (Germany and Japan). A new study by the Health Care Financing Administration warns that health care spending may nearly double to $2.1 trillion by 2007. Yet the industry is perceived to be too "resource-constrained" to assure health care services for all citizens. This poses a key question: Are there too few resources, or are we simply not allocating them in the best ways possible? Health care's "double bottom line"--social and economic accountability--typifies the social and economic milieu of health care as the final pages turn on the 20th Century. And, it is this duality that forms the underlying theme for the landmark study--Leadership for a Healthy 21st Century--conducted over the course of the past year by Arthur Andersen and The Healthcare Forum Foundation, with primary research support from DYG, Inc. and Baruch Lev, professor at the Stern School of Business, New York University. The study was designed to investigate a new economic model emerging in the information economy and its impact on health care; the evolving values of consumers in relation to business, health and health care; and the values of

    Polysialic acid (polySia) is mainly found as a modification of neural cell adhesion molecule (NCAM) in whole embryonic brains, as well as restricted areas of adult vertebrate brains, including the hippocampus. PolySia shows not only repulsive effects on NCAM-involved cell-cell interactions due to its bulky and hydrated properties, but also attractive effects on the interaction with neurologically active molecules, which exerts a reservoir function. Two different polysialyltransferases, ST8SIA2 and ST8SIA4, are involved in the synthesis of polySia chains; however, to date, the differences of the properties between polySia chains synthesized by these two enzymes remain unknown. In this study, to clarify this point, we first prepared polySia-NCAMs from HEK293 cells stably expressing ST8SIA4 and ST8SIA2, or ST8SIA2 (SNP-7), a mutant ST8SIA2 derived from a schizophrenia patient. The conventional sensitive chemical and immunological characterizations showed that the quantity and quality (structural features) of polySia are not so much different between ST8SIA4- and ST8SIA2-synthesized ones, apart from those of ST8SIA2 (SNP-7). Then, we assessed the homophilic and heterophilic interactions mediated by polySia-NCAM by adopting a surface plasmon resonance measurement as an in vitro analytical method. Our novel findings are as follows: (i) the ST8SIA2- and ST8SIA4-synthesized polySia-NCAMs exhibited different attractive and repulsive effects than each other; (ii) both polySia- and oligoSia-NCAMs synthesized by ST8SIA2 were able to bind polySia-NCAMs; (iii) the polySia-NCAM synthesized by a ST8SIA2 (SNP-7) showed markedly altered attractive and repulsive properties. Collectively, polySia-NCAM is suggested to simultaneously possess both attractive and repulsive properties that are highly regulated by the two polysialyltransferases. © The Author 2017.

    2002-01-01

    This period of LEP dismantling and LHC installation is a real challenge for the ST-HM group. The group is now following several projects to cope with the diversity of requests. Although crane design and procurement still constitutes the majority of the workload, more and more of our time is nowadays dedicated to providing alternative handling solutions. In 2001/2002, our main studies concern cranes for LHC, industrial and shielded motorised doors, the upgrade/replacement of 32 lifts and mobile cranes. The years 2002/2003 will concern mainly the study of LHC handling systems such as trailers and heavy-duty tractors, specifically tailored containers and tools. In parallel, the monorail will be extended in the injection tunnel and CNGS tunnels and a new monorail system for TOF will be installed. Since the tunnel monorail infrastructure will be used for power feed and guidance purposes only, this requires that other transport systems be studied, such as forklift trucks, industrial and telescopic hoists.

    Energy Technology Data Exchange (ETDEWEB)

    2004-07-01

    The Federal government plays a key role in supporting the country's science infrastructure, a national treasure, and scientific research, an investment in our future. Scientific discoveries transform the way we think about our universe and ourselves, from the vastness of space to molecular-level biology. In innovations such as drugs derived through biotechnology and new communications technologies we see constant evidence of the power of science to improve lives and address national challenges. We had not yet learned to fly at the dawn of the 20th century, and could not have imagined the amazing 20th century inventions that we now take for granted. As we move into the 21st century, we eagerly anticipate new insights, discoveries, and technologies that will inspire and enrich us for many decades to come. This report presents the critical responsibilities of our Federal science enterprise and the actions taken by the Federal research agencies, through the National Science and Technology Council, to align our programs with scientific opportunity and with national needs. The many examples show how our science enterprise has responded to the President's priorities for homeland and national security, economic growth, health research, and the environment. In addition, we show how the science agencies work together to set priorities; coordinate related research programs; leverage investments to promote discovery, translate science into national benefits, and sustain the national research enterprise; and promote excellence in math and science education and work force development.

    In order to investigate the effects of a light-element limiter on plasma parameters, aluminum rail limiters interchangeable with Mo rails were installed top, bottom, and outside directions in the ST tokamak. The inside limiter remained a fixed Mo rail. Compared with discharges produced immediately before and after with the usual Mo limiters, the ''aluminum'' discharges showed an increase of T/sub e/ (by factors of 1.4-2 near the center) and of energy confinement (by factors of 2 to 3 in el. energy/power input, depending on time of observation). H 2 and He discharges showed practically identical effects. In plasma composition, the Mo concentration dropped significantly, but Fe only slightly if at all; the Al concentration was about 3-5 percent (i.e., large compared to the heavier metals), whereas oxygen, about 4 to 8 percent to start with, dropped to insignificance, probably as a result of Al evaporation. The z/sub eff/ from resistivity increased 20-30 percent although the resistance dropped because of the higher T/sub e/. The improved T/sub e/ and energy confinement are thought to be the result of cumulative effects of more favorable radial current and power input distributions rather than direct energy losses by radiation

    The Fort St. Vrain (FSV) station, a 330-MW(e) single reheat steam cycle powered by a high-temperature gas-cooled reactor (HTGR), is the first HTGR to enter commercial operation. Designed and built by General Atomic Company (GA), the plant is owned and operated by Public Service Company of Colorado (PSC). Many unique design features have been incorporated into this reactor system, including high-pressure helium as the primary system coolant, a graphite-moderated prismatic block core design, fission-product-containing carbide coatings on both fissile and fertile fuel particles, steam-driven helium circulators turning on water bearings, and once-through steam generators. All of these systems are contained in a prestressed concrete reactor vessel (PCRV). Extensive testing has been conducted during the rise to power following first criticality early in 1974 to verify system design performance. During this period, the plant has operated at power levels up to 70% and produced over one billion kilowatt hours of electricity. In 1979, the first refueling was conducted in conjunction with an extensive in-core inspection, the addition of in-core instrumentation, and a planned removal of a circulator for inspection.

  4. Ionizing radiation in 21st century

    2005-01-01

    The paper begins with the author's personal experience in Poland on the occasion of Chernobyl nuclear accident followed by main lessons that the author could deduce from the accident. After the discovery of ionizing radiation at the end of 19th century, social perception has altered between acceptance and rejection stemming from recognition of the basic aspects: usefulness for medical applications and for technical and scientific aims, beneficial effects of their low levels, and harmful effects of high levels. The author explains how linear no-threshold (LNT) assumption according to which even the lowest, near zero doses of radiation may cause cancer genetic harm has become established. Comparing the natural radioactivity of the earth's crust with the activity of much shorter-lived radioactive wastes from the nuclear power cycle, it is concluded that none of the man-made component of the radioactive wastes has higher-toxicity than the natural Th 232. The paper concludes by stating that one century has not been long enough to adapt mentally to ionizing radiation and radioactivity and perhaps 21st century will suffice for this adaptation. (S.

    We are truly fortunate to live in one of the great epochs of human discovery, a time when science is providing new visions and understanding about ourselves and the world in which we live. At last, we are beginning to explore the Universe itself. One particularly exciting area of advancement is high-energy physics where several existing concepts will be put to the test. A brief survey will be given of accomplishments in 20th Century physics. These include relativity and quantum physics which have produced breakthroughs in cosmology, astrophysics, and high-energy particle physics. The current situation is then assessed, combining the last 100 years of progress with new 21st Century challenges about unification and where to go next. Finally, the future is upon us. The next frontier in experimental high-energy physics, the Large Hadron Collider (LHC) at CERN in Geneva, is scheduled to begin coming online this year (2007). The potential for the LHC to address several of the significant problems in physics today will be discussed, as this great accelerator examines the predictions of the Standard Model of particle physics and even cosmology. New physics and new science will surely emerge and a better vision of the world will unfold.

  6. Departure into the 21st century

    At its 51st annual meeting, the Association of Industrial Power Companies (VIK) commented upon the items relating to energy and to the environment contained in the coalition agreement of the Social Democratic Party (SPD) and Alliance 90/The Greens, expressing the point of view of industry and trade. In the opinion of the VIK the plans to opt out of nuclear power have not been fully thought out as far as repercussions on the labor market and on energy policy are concerned. Nuclear power must not be given up at the expense of industry engaged in international competition and the jobs provided by industry. Opting out of nuclear power quickly and without indemnification is unacceptable. The VIK regards the labor market effects of any measure planned as the yardstick to be applied to the coalition agreement. Any decision about energy policy must be seen in connection with the deregulation of the electricity and gas markets. The VIK also holds a critical view of the coalition's intention to amend the Power Economy Act adopted only recently. (orig.) [de

    Biofabrication can be defined as the production of complex living and non-living biological products from raw materials such as living cells, molecules, extracellular matrices, and biomaterials. Cell and developmental biology, biomaterials science, and mechanical engineering are the main disciplines contributing to the emergence of biofabrication technology. The industrial potential of biofabrication technology is far beyond the traditional medically oriented tissue engineering and organ printing and, in the short term, it is essential for developing potentially highly predictive human cell- and tissue-based technologies for drug discovery, drug toxicity, environmental toxicology assays, and complex in vitro models of human development and diseases. In the long term, biofabrication can also contribute to the development of novel biotechnologies for sustainable energy production in the future biofuel industry and dramatically transform traditional animal-based agriculture by inventing 'animal-free' food, leather, and fur products. Thus, the broad spectrum of potential applications and rapidly growing arsenal of biofabrication methods strongly suggests that biofabrication can become a dominant technological platform and new paradigm for 21st century manufacturing. The main objectives of this review are defining biofabrication, outlining the most essential disciplines critical for emergence of this field, analysis of the evolving arsenal of biofabrication technologies and their potential practical applications, as well as a discussion of the common challenges being faced by biofabrication technologies, and the necessary conditions for the development of a global biofabrication research community and commercially successful biofabrication industry.

    In the last century, vaccination has been the most effective medical intervention to reduce death and morbidity caused by infectious diseases. It is believed that vaccines save at least 2–3 million lives per year worldwide. Smallpox has been eradicated and polio has almost disappeared worldwide through global vaccine campaigns. Most of the viral and bacterial infections that traditionally affected children have been drastically reduced thanks to national immunization programs in developed countries. However, many diseases are not yet preventable by vaccination, and vaccines have not been fully exploited for target populations such as elderly and pregnant women. This review focuses on the state of the art of recent clinical trials of vaccines for major unmet medical needs such as HIV, malaria, TB, and cancer. In addition, we describe the innovative technologies currently used in vaccine research and development including adjuvants, vectors, nucleic acid vaccines, and structure-based antigen design. The hope is that thanks to these technologies, more diseases will be addressed in the 21st century by novel preventative and therapeutic vaccines. PMID:24803000

    A description is given of Fort St. Vrain hot functional tests performed to evaluate the initial nonnuclear performance of the primary coolant system and the associated effects on the various internal components of the reactor vessel and primary coolant system. The components included the twelve steam generator modules, the four helium circulators, the PCRV thermal barrier and liner coolant system, the helium purification system, and the primary and secondary closures at each of the PCRV penetrations. Additional objectives included analysis of the parallel operation of the four helium circulators and the performance of several circulator start/stop transients under various conditions of primary coolant temperature and pressure. Vibration and acoustical phenomena within the vessel were measured, recorded, and compared to theoretical analyses; a verification of reverse flow in the shutdown loop steam generator during one loop operation was performed; the PCRV was again observed for its structural response to internal pressure; and comparisons were made relative to data recorded during the initial pressure test completed in July 1971.

    'Engineering Toxins for 21st Century Therapies' (9-10 September 2010) was part of the Royal Society International Seminar series held at the Kavli International Centre, UK. Participants were assembled from a range of disciplines (academic, industry, regulatory, public health) to discuss the future potential of toxin-based therapies. The meeting explored how the current structural and mechanistic knowledge of toxins could be used to engineer future toxin-based therapies. To date, significant progress has been made in the design of novel recombinant biologics based on domains of natural toxins, engineered to exhibit advantageous properties. The meeting concluded, firstly that future product development vitally required the appropriate combination of creativity and innovation that can come from the academic, biotechnology and pharma sectors. Second, that continued investigation into understanding the basic science of the toxins and their targets was essential in order to develop new opportunities for the existing products and to create new products with enhanced properties. Finally, it was concluded that the clinical potential for development of novel biologics based on toxin domains was evident. © 2011 The Authors Journal compilation © 2011 FEBS.

    The dynamics of spherical torus (ST) plasmas, when the external toroidal magnetic field is decreased to zero and then increased in the opposite direction, has been investigated using three-dimensional magnetohydrodynamic (MHD) numerical simulations. It has been found that the flipped ST configuration is self-organized after the ST configuration collapses because of the growth of the n = 1 mode in the open flux region and a following magnetic reconnection event. During the transition between these configurations, not only the paramagnetic toroidal field but also the poloidal field reverses polarity spontaneously. (letter to the editor)

    Fourteen osteosarcomas were observed among the eight St. Bernards that died following the injection of 239 Pu. Early data tentatively indicate that the St. Bernard is about 5 times more sensitive than the beagle and about 130 times more sensitive than the average person is estimated to be to 239 Pu-induced bone sarcomas. Thus the St. Bernard may be an excellent model in which to study the pathogenesis of bone cancer induction, to evaluate the relationship between spontaneous susceptibility and radiosensitivity, and to determine whether radiosensitivity significantly affects the toxicity ration of 239 Pu/ 226 Ra

    ST Microelectronics microcontrollers and processors are readily available, capable and economical processors. Unfortunately they lack a broad user base like similar offerings from Texas Instrument, Atmel, or Microchip. All of these devices could be useful in economical devices for remote sensing applications used with environmental sensing. With the increased need for environmental studies, and limited budgets, flexibility in hardware is very important. To that end, and in an effort to increase open support of ST devices, I am sharing my teams' experience in interfacing a common environmental sensor communication protocol (SDI-12) with ST devices.

    Full Text Available Takotsubo cardiomyopathy (TCM is usually characterized by transient left ventricular apical ballooning. Due to the clinical symptoms which include chest pain, electrocardiographic changes, and elevated myocardial markers, Takotsubo cardiomyopathy is frequently mimicking ST-elevation myocardial infarction in the absence of a significant coronary artery disease. Otherwise an acute occlusion of the left anterior descending coronary artery can produce a typical Takotsubo contraction pattern. ST-elevation myocardial infarction (STEMI is frequently associated with emotional stress, but to date no cases of STEMI triggering TCM have been reported. We describe a case of a female patient with inferior ST-elevation myocardial infarction complicated by TCM.

    2013-12-01

    Full Text Available One of the most widely venerated saints in the Middle Ages was St. Martin of Tours whose cult continues to this day in many parts of the world. In the Middle Ages, he became as popular as other major saints such as Thomas Becket, Santiago de Compostela and the Virgin Mary. St. Martin’s cult became very prominent in the Iberian Peninsula before and after the emergence of the cult of Santiago de Compostela. In St. Vicent Ferrer’s voluminous sermons this one in Catalán is dedicated to this most venerated Gallic saint. The most important late antique and early medieval sources that form the background of this sermon are by Sulpicius Severus- the Gallus and Vita Sancti Martini. In the high Middle Ages, however, his cult was popularized through the Legenda Aurea written by the Dominican Jacobus of Voragine, who synthesized Sulpicius’ two works on St. Martin. Moreover, St. Vicent preached not to make any major doctrinal breakthroughs- his main interest was to evangelize, not to write academic theology- he nevertheless exhibited great creativity. The object of this study is St. Vicent’s Catalán sermon Alius Sermo Sancti Martini, CXXXIV.Uno de los santos más venerados en la edad media fue San Martín de Tours, cuyo culto continúa hasta hoy en muchas partes del mundo.

    Full Text Available History of present illness: An 80-year-old female with a history of Crohn’s disease presented to the emergency department with chest pain. She had two weeks of exertional chest pain that preceded an episode of chest pain immediately prior to arrival associated with diaphoresis. Her pain nearly completely resolved with sublingual nitroglycerin provided by pre-hospital personnel. She was hemodynamically stable with normal vital signs on arrival. An ECG was immediately obtained. Significant findings: The ECG shows ST-segment depressions in precordial leads V3 through V6, and limb leads I, II, and aVL, and 1 mm of ST-segment elevation in aVR. The initial troponin I was elevated at 1.37 ng/mL (upper limit of normal 0.40. Cardiology decided to delay catheterization until the next day when diffuse coronary disease was discovered (including 90% of the left circumflex stenosis, 60% proximal and 75% mid-left anterior descending stenosis, 75% third diagonal branch stenosis, and 90% posterior descending artery stenosis. The following day, the patient went to the operating room for coronary artery bypass grafting (CABG. Discussion: Traditionally, lead aVR has not received attention when interpreting acutely ischemic changes on ECG, leading some to refer to it as “the forgotten lead.”1 Current guidelines acknowledge the significance of multilead ST depression with coexistent ST elevation in aVR, and this pattern has been identified as the strongest predictor of severe left main coronary artery and/or 3-vessel disease (LM/3VD.2-3 When this ECG pattern is recognized in patients with ischemic symptoms, the emergency physician should involve cardiology early. When managing patients with suspected LM/3VD, it is important to withhold dual anti-platelet therapy as CABG is likely to be indicated,1,3 and guidelines recommend discontinuing P2Y12 inhibitors like clopidogrel or ticagrelor at least 24 hours prior to urgent CABG.2

    Polysaccharide (ST) was prepared from Sargassum thunbergii using hot water. Two fractions (ST-1 and ST-2) were prepared using anion exchange chromatography. One desulfated polysaccharide (ST-1-DS) was also prepared. Electrospray ionization mass spectrometry (ESI-MS) performed on ST-1-DS showed that the desulfated polysaccharides contained methyl glycosides of mono-sulfated and di-sulfated galacto-fucooligosaccharides. This result suggested that ST-1 might contain sulfated galactofucan, which consists of a backbone of alternating (Gal) n and (Fuc) n and sulfated randomly on Gal and mainly on C-2 in Fuc. In addition, ST-1 was degraded in 1M sulfuric acid. The solution was centrifuged, and the supernatant was concentrated and precipitated in ethanol to obtain the precipitate (ST-1-P). ST-1-P was then separated using gel chromatography and anion exchange chromatography to obtain the oligomers. ESI-MS spectra of oligomers indicated that ST-1 mostly contained sulfated glucuronomannan and fucoglucuronan. ESI-MS with collision-induced dissociation tandem mass spectrometry (ESI-CID-MS/MS) suggested that glucuronomannan contained alternating 2-linked Man and 4-linked GlcA, while fucoglucuronan contained 4-linked glucuronan with branched Fuc at C-3. Finally, the neuroprotective activities of ST, ST-1, ST-2 and MIX (a mixture of ST-1 and ST-2) were determined. ST showed the most neuroprotective activity, which indicated that ST might be a good candidate for curing neurodegenerative diseases. Copyright © 2017 Elsevier B.V. All rights reserved.

    Lithium is an important industrial compound and the principal component of high energy-density batteries. Because it is the lightest solid element, these batteries are widely used in consumer electronics and are expected to be the basis for battery electric vehicles (BEVs), hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) for the 21st century. In view of the large incremental demand for lithium that will result from expanded use of various types of EVs, long-term estimates of lithium demand and supply are advisable. For GDP growth rates of 2 to 3% and battery recycling rates of 90 to 100%, total demand for lithium for all markets is expected to be a maximum of 19.6 million tonnes through 2100. This includes 3.2 million tonnes for industrial compounds, 3.6 million tonnes for consumer electronics, and 12.8 million tonnes for EVs. Lithium-bearing mineral deposits that might supply this demand contain an estimated resource of approximately 39 million tonnes, although many of these deposits have not been adequately evaluated. These lithium-bearing mineral deposits are of two main types, non-marine playa-brine deposits and igneous deposits. Playa-brine deposits have the greatest immediate resource potential (estimated at 66% of global resources) and include the Salar de Atacama (Chile), the source of almost half of current world lithium production, as well as Zabuye (China/Tibet) and Hombre Muerto (Argentina). Additional important playa-brine lithium resources include Rincon (Argentina), Qaidam (China), Silver Peak (USA) and Uyuni (Bolivia), which together account for about 35% of the estimated global lithium resource. Information on the size and continuity of brine-bearing aquifers in many of these deposits is limited, and differences in chemical composition of brines from deposit to deposit require different extraction processes and yield different product mixes of lithium, boron, potassium and other elements. Numerous other brines in playas

    2003-08-01

    Toward the end of the twentieth century, it became evident to professionals working within the meterological arena that the world's climate system was showing signs of change that could not be adequately explained in terms of natural variation. Since that time there has been an increasing recognition that the climate system is changing as a result of human industries and lifestyles, and that the outcomes may prove catastrophic to the world's escalating population. Compiled by an international team formed under the auspices of the World Meteorological Organization (WMO), Climate: Into the 21st Century features an unrivalled collection of essays by the world's leading meteorological experts. These fully integrated contributions provide a perspective of the global climate system across the twentieth century, and describe some of the most arresting and extreme climatic events and their effects that have occurred during that time. In addition, the book traces the development of our capabilities to observe and monitor the climate system, and outlines our understanding of the predictability of climate on time-scales of months and longer. It concludes with a summary of the prospects for applying the twentieth century climate experience in order to benefit society in the twenty-first century. Lavishly illustrated in color, Climate is an accessible acccount of the challenges that climate poses at the start of the twenty-first century. Filled with fascinating facts and diagrams, it is written for a wide audience and will captivate the general reader interested in climate issues, and will be a valuable teaching resource. William Burroughs is a successful science author of books on climate, including Weather (Time Life, 2000), and Climate Change: A Multidisciplinary Approach (2001), Does the Weather Really Matter? (1997) and The Climate Revealed (1999), all published by Cambridge University Press.

  19. Pediatrics in 21st Century and Beyond.

    Pediatrics is a dynamic discipline and there is awareness and hope for actualizing outstanding achievements in the field of child health in 21 st century and beyond. Improved lifestyle and quality of children's health is likely to reduce the burden of adult diseases and enhance longevity because seeds of most adult diseases are sown in childhood. Identification and decoding of human genome is expected to revolutionize the practice of pediatrics. The day is not far off when a patient will walk into doctor's chamber with an electronic or digital health history on a CD or palmtop and a decoded genomic constitution. There will be reduced burden of genetic diseases because of selective abortions of "defective" fetuses and replacement of "bad" genes with "good" ones by genetic engineering. Availability of totipotent stem cells and developments in transplant technology are likely to revolutionize the management of a variety of hematologic cancers and life-threatening genetic disorders. The possibility of producing flawless designer babies by advances in assisted reproductive technologies (ARTs) is likely to be mired by several ethical and legal issues.The availability of newer vaccines by recombinant technology for emerging infective and for non-infective lifestyle diseases is likely to improve survival and quality of life. There is going to be a greater focus on the "patient" having the disease rather than "disease" per se by practicing holistic pediatrics by effective utilization of alternative or complementary strategies for health care. Due to advances in technology, pediatrics may get further dehumanized. A true healer cannot simply rely on technology; there must be a spiritual bond between the patient and the physician by exploiting the concept of psycho-neuro-immunology and body-mind interactions. In the years to come, physicians are likely to play "god" but medicine can't achieve immortality because anything born must die in accordance with nature's recycling

  20. 21st Century's energy: Hydrogen energy system

    International Nuclear Information System (INIS)

    Veziroglu, T. Nejat; Sahin, Suemer

    2008-01-01

    Fossil fuels (i.e., petroleum, natural gas and coal), which meet most of the world's energy demand today, are being depleted fast. Also, their combustion products are causing the global problems, such as the greenhouse effect, ozone layer depletion, acid rains and pollution, which are posing great danger for our environment and eventually for the life in our planet. Many engineers and scientists agree that the solution to these global problems would be to replace the existing fossil fuel system by the hydrogen energy system. Hydrogen is a very efficient and clean fuel. Its combustion will produce no greenhouse gases, no ozone layer depleting chemicals, little or no acid rain ingredients and pollution. Hydrogen, produced from renewable energy (e.g., solar) sources, would result in a permanent energy system, which we would never have to change. However, there are other energy systems proposed for the post-petroleum era, such as a synthetic fossil fuel system. In this system, synthetic gasoline and synthetic natural gas will be produced using abundant deposits of coal. In a way, this will ensure the continuation of the present fossil fuel system. The two possible energy systems for the post-fossil fuel era (i.e., the solar-hydrogen energy system and the synthetic fossil fuel system) are compared with the present fossil fuel system by taking into consideration production costs, environmental damages and utilization efficiencies. The results indicate that the solar-hydrogen energy system is the best energy system to ascertain a sustainable future, and it should replace the fossil fuel system before the end of the 21st century

  2. Diagnostic Development for ST Plasmas on NSTX

    International Nuclear Information System (INIS)

    Johnson, D.

    2003-01-01

    Spherical tokamaks (STs) have much lower aspect ratio (a/R) and lower toroidal magnetic field, relative to tokamaks and stellarators. This paper will highlight some of the challenges and opportunities these features pose in the diagnosis of ST plasmas on the National Spherical Torus Experiment (NSTX), and discuss some of the corresponding diagnostic development that is underway. The low aspect ratio necessitates a small center stack, with tight space constraints and large thermal excursions, complicating the design of magnetic sensors in this region. The toroidal magnetic field on NSTX is less than or equal to 0.6 T, making it impossible to use ECE as a good monitor of electron temperature. A promising new development for diagnosing electron temperature is electron Bernstein wave (EBW) radiometry, which is currently being pursued on NSTX. A new high-resolution charge exchange recombination spectroscopy system is being installed. Since non-inductive current initiation and sustainment ar e top-level NSTX research goals, measurements of the current profile J(R) are essential to many planned experiments. On NSTX several modifications are planned to adapt the MSE technique to lower field, and two novel MSE systems are being prototyped. Several high speed 2-D imaging techniques are being developed, for viewing both visible and x-ray emission. The toroidal field is comparable to the poloidal field at the outside plasma edge, producing a large field pitch (>50 o ) at the outer mid-plane. The large shear in pitch angle makes some fluctuation diagnostics like beam emission spectroscopy very difficult, while providing a means of achieving spatial localization for microwave scattering investigations of high-k turbulence, which are predicted to be virulent for NSTX plasmas. A brief description of several of these techniques will be given in the context of the current NSTX diagnostic set

  3. Myocarditis with ST elevation and elevated cardiac enzymes misdiagnosed as an ST-elevation myocardial infarction.

    2012-12-01

    Acute myocarditis can mimic ST-elevation myocardial infarction (STEMI). Quickly determining the correct diagnosis is critical given the "time is muscle" implication with a STEMI and the potential adverse effects associated with use of fibrinolytic therapy. A 46-year-old man presented to a rural emergency department with chest pain, and an electrocardiogram (ECG) read as showing 0.1 mV of ST-segment elevation in leads III and aVF. His initial cardiac troponin T was 0.44 ng/mL. He received fibrinolytic therapy for presumed STEMI. Cardiac magnetic resonance imaging was later performed and showed epicardial delayed enhancement consistent with myocarditis. Upon further questioning, he acknowledged 3 days of stuttering chest discomfort and a recent upper respiratory infection, as well as similar chest pain in his wife. A systematic evaluation is essential for acute chest pain, including a focused history, identification of cardiac risk factors, and ECG interpretation. A history of recent viral illness, absence of cardiac risk factors, or ECG findings inconsistent with a single anatomic lesion would suggest a potential alternate diagnosis to STEMI. This case emphasizes the importance of a focused history in the initial evaluation of chest pain. Copyright © 2012 Elsevier Inc. All rights reserved.

    2002-01-01

    This paper describes the ST/EL and ST/CV services for TI2 & TI8 LHC injection tunnels. The cooling and ventilation part describes the requirements for design and installation of more than 10 km of pipeline that is going to be laid down in the tunnels. Main operating parameters as well as manufacture procedures are explained. Preliminary work schedule with the cost estimate is also presented. Electrical power will be distributed from the LHC side and the SPS side for the machine and the general services. All power converters will be installed on surface buildings. The link between the main bend converters and the main bend magnets will be realised with water-cooled cables. Rest of the magnets will be cabled by using conventional copper and aluminium cables. Due to long lengths of the injection tunnels a dry 18kV transformer will be installed in TJ8 to serve the general services for TI8. The same will apply to TI2 by installing a transformer at the bottom of the PMI2 shaft.

    The persistence of ST segment depression in recovery signifies a strongly positive exercise treadmill test (ETT). However, it is unclear if early recovery of ST segments portends a similar prognosis. We sought to determine if persistence of ST depression into recovery correlates with ischemic burden based on myocardial perfusion imaging (MPI). This was a retrospective analysis of 853 consecutive patients referred for exercise MPI at a tertiary academic center over a 24-month period. Patients were stratified into three groups based on the results of the ETT: normal (negative ETT), persistence (positive ETT with >1mm ST segment depression at 1minute in recovery) and early normalization (positive ETT with normalization, while 105 patients met criteria for persistence. The persistence group had a significantly greater SSS (8.48±7.77) than both the early normalization (4.34±4.98, pnormal (4.47±5.31, pnormalization and normal groups were not statistically different and met the prespecified non-inferiority margin (mean difference 0.12, -0.66=lower 95% CI, pnormal and 7.4% of early normalization groups. Among patients with an electrically positive ETT, recovery of ST segment depression within 1minute was associated with a lower SSS than patients with persistence of ST depression beyond 1minute. Furthermore, early ST segment recovery conferred a similar SSS to patients with a negative ETT. These results suggest that among patients evaluated for chest pain with a positive ETT, early recovery of the ST segment during recovery is associated with a significantly less ischemic burden on subsequent MPI and thus may represent a false positive finding in exercise treadmill testing.

    The St. George recoil mass separator has recently been coupled to the 5MV St. Ana accelerator at the University of Notre Dame's Nuclear Science Lab. St. George is a unique tool designed to measure radiative alpha-capture reactions for nuclei up to A = 40 in inverse kinematics in order to directly obtain cross sections required for astrophysical models of stellar and explosive helium burning. Commissioning of St. George is presently taking place with primary beams of hydrogen, helium, and oxygen. In this presentation, results will be shown for the measured energy acceptance of St. George, which compare favorably to COSY results when employing the calculated optimal ion-optical settings. Additionally, future plans will be discussed, such as assessing the angular acceptance of St. George and the re-integration of HiPPO at the separator target position to provide a dense, windowless helium gas-jet target. The material presented in this work is partially supported by the National Science Foundation Grant No. 1419765.

    To explain the clinical significance of stress(st)-induced ST-segment (ST) changes postinfarction, 93 patients with previous myocardial infarction (MI) were performed st- 201 Tl myocardial single photon emission computed tomography (SPECT) and compared ST changes with SPECT, coronary arteriographic and left ventriculographic findings. 30 out of 93 cases (32%) had ST depression, 20 (21.5%) had ST elevation, 9 (10%) had both ST depression and elevation and remaining 34 (36.5 %) had no significant ST changes. In single vessel disease, ST depression were noted in 29% (12/42), while in multivessel disease, 53% (27/51). 35 out of 39 cases (90%) with ST depression had transient perfusion defect but no apparent relation was noted between location of ST depression on ECG and region of transient perfusion defect in SPECT. All of 28 cases with ST elevation were noted in anterior MI cases, and 26 out of these showed severe LV wall motion abnormality in contrast left ventriculography and broad anterior permanent defect in SPECT. Only 15 cases (54%) showed slight redistribution. Thus, we conclude that in patients with previous MI, st-induced ST depression seems to reflect myocardial ischemia and ST elevation possibly related abnormal LV wall motion. (author)

    responses to the environment. A major challenge for life scientists in the 21st century is to understand how a changing environment impacts all life on earth. A full understanding of the capabilities of organisms to respond to environmental variation, and the resilience of organisms challenged by environmental changes and extremes, is necessary for understanding the impact of pollution and climatic change on the viability of populations. Comparative endocrinologists have a key role to play in these efforts.

    Geoscience knowledge and skills play new roles in the workforce as our society addresses the challenges of living safely and sustainably on Earth. As a result, we expect a wider range of future career opportunities for students with education in the geosciences and related fields. A workshop offered by the InTeGrate STEP Center on 'Geoscience and the 21st Century Workforce' brought together representatives from 24 programs with a substantial geoscience component, representatives from different employment sectors, and workforce scholars to explore the intersections between geoscience education and employment. As has been reported elsewhere, employment in energy, environmental and extractive sectors for geoscientists with core geology, quantitative and communication skills is expected to be robust over the next decade as demand for resources grow and a significant part of the current workforce retires. Relatively little is known about employment opportunities in emerging areas such as green energy or sustainability consulting. Employers at the workshop from all sectors are seeking the combination of strong technical, quantitative, communication, time management, and critical thinking skills. The specific technical skills are highly specific to the employer and employment needs. Thus there is not a single answer to the question 'What skills make a student employable?'. Employers at this workshop emphasized the value of data analysis, quantitative, and problem solving skills over broad awareness of policy issues. Employers value the ability to articulate an appropriate, effective, creative solution to problems. Employers are also very interested in enthusiasm and drive. Participants felt that the learning outcomes that their programs have in place were in line with the needs expressed by employers. Preparing students for the workforce requires attention to professional skills, as well as to the skills needed to identify career pathways and land a job. This critical

    This paper provides an overview of some of the environmental challenges facing the uranium production industry in the 21st century. For many years, the linear, non-threshold (LNT) model has been regarded as a prudent hypothesis for radiation protection purposes. This paradigm has been challenged at the same time for both underestimating and overestimating the risks from ionizing radiation. The reality is that the ability of conventional epidemiology to distinguish small risks will always be limited by statistical power at low doses. In the future, there will be increased emphasis on better understanding the effects of ionizing radiation at the cellular (and sub cellular) level. The concept of 'controllable dose' has been proposed as an alternative to the ICRP's current approach to dose limitation. The concept is that if the most exposed individual is protected, then society as a whole is protected. A hazard ranking scale based on comparisons to natural background levels of radiation has been proposed. Adoption of a concept such as 'controllable dose' would require a parallel re-evaluation of the concepts and application of collective dose and ALARA optimization. The protection of non-human biota is an issue of considerable interest in many countries. The science in this area is rapidly evolving, as are discussions of a more philosophical nature. For example, should the focus of environmental risk assessment be the sustainability of the population or should the focus be to limit effects on a single member of the population? The future of environmental risk assessment should be of great interest to the uranium production industry. A systematic approach to risk assessment addressing the full scope of potential hazards - environmental, human health, engineering, financial and others - will be increasingly important in the future. What level of risk is it reasonable to accept? What is meant by 'reasonable'? How much risk can be engineered away, for how long, and at what

    We analysed the microbiological traits and population structure of KPC-producing Enterobacteriaceae isolates collected in Spain between 2012 and 2014. We also performed a comparative WGS analysis of the three major KPC-producing Klebsiella pneumoniae clones detected. Carbapenemase and ESBL genes were sequenced. The Institut Pasteur MLST scheme was used. WGS data were used to construct phylogenetic trees, to identify the determinants of resistance and to de novo assemble the genome of one representative isolate of each of the three major K. pneumoniae clones. Of the 2443 carbapenemase-producing Enterobacteriaceae isolates identified during the study period, 111 (4.5%) produced KPC. Of these, 81 (73.0%) were K. pneumoniae and 13 (11.7%) were Enterobacter cloacae. Three major epidemic clones of K. pneumoniae were identified: ST11/KPC-2, ST101/KPC-2 and ST512/KPC-3. ST11/KPC-2 differed from ST101/KPC-2 and ST512/KPC-3 by 27 819 and 6924 SNPs, respectively. ST101/KPC-2 differed from ST512/KPC-3 by 28 345 SNPs. Nine acquired resistance genes were found in ST11/KPC-2, 11 in ST512/KPC-3 and 13 in ST101/KPC-2. ST101/KPC-2 had the highest number of virulence genes (20). An 11 bp deletion at the end of the mgrB sequence was the cause of colistin resistance in ST512/KPC-3. KPC-producing Enterobacteriaceae are increasing in Spain. Most KPC-producing K. pneumoniae isolates belonged to only five clones: ST11 and ST512 caused interregional spread, ST101 caused regional spread and ST1961 and ST678 produced independent hospital outbreaks. ST101/KPC-2 had the highest number of resistance and virulence genes. ST101/KPC-2 and ST512/KPC-3 were recently implicated in the spread of KPC in Italy. © The Author 2016.

    Neisseria meningitidis is a leading bacterial cause of sepsis and meningitis globally with dynamic strain distribution over time. Beginning with an epidemic among Hajj pilgrims in 2000, serogroup W (W) sequence type (ST) 11 emerged as a leading cause of epidemic meningitis in the African 'meningitis belt' and endemic cases in South America, Europe, Middle East and China. Previous genotyping studies were unable to reliably discriminate sporadic W ST-11 strains in circulation since 1970 from the Hajj outbreak strain (Hajj clone). It is also unclear what proportion of more recent W ST-11 disease clusters are caused by direct descendants of the Hajj clone. Whole genome sequences of 270 meningococcal strains isolated from patients with invasive meningococcal disease globally from 1970 to 2013 were compared using whole genome phylogenetic and major antigen-encoding gene sequence analyses. We found that all W ST-11 strains were descendants of an ancestral strain that had undergone unique capsular switching events. The Hajj clone and its descendants were distinct from other W ST-11 strains in that they shared a common antigen gene profile and had undergone recombination involving virulence genes encoding factor H binding protein, nitric oxide reductase, and nitrite reductase. These data demonstrate that recent acquisition of a distinct antigen-encoding gene profile and variations in meningococcal virulence genes was associated with the emergence of the Hajj clone. Importantly, W ST-11 strains unrelated to the Hajj outbreak contribute a significant proportion of W ST-11 cases globally. This study helps illuminate genomic factors associated with meningococcal strain emergence and evolution.

    Full Text Available Over the past several years, Hmong in the United States have gained prominence for their increasing involvement in politics. Most of the attention has understandably focused on Fresno, California and St. Paul, Minnesota, home to the two largest Hmong populations in this country. While the Hmong communities in both cities are similar in size and have made significant political progress as evidenced by the election of Hmong candidates, the Hmong community in St. Paul has made greater inroads in the political realm. In addition to the elections of two Hmong candidates to the Minnesota State Legislature and two to the St. Paul School Board, the Hmong community in St. Paul has been able to engage local and state governments in Minnesotato address issues that affect the Hmong community. Through interviews, census data, and newspaper coverage of political campaigns, I show that Hmong in St. Paul have achieved greaterrepresentation in local and state governments and received greater support from government officials than Hmong in Fresno because Minnesota offers a social, economic, and politicalcontext that is favorable to fostering Hmong political involvement. Compared to Hmong in Fresno, Hmong in St. Paul have higher levels of socioeconomic resources and are more visible given their large size relative to other minority groups. They live in a region with consistently high levels of political participation and have political candidates who devote resources to mobilizing the Hmong community. Moreover, the Hmong vote has been critical to the success of Hmong candidates in St. Paul, an indication of the increasing political clout of the Hmong community there and a major reason why politicians in Minnesota are more willing to respond toissues that affect the Hmong community. Overall, this study highlights the importance of local and regional context in understanding the political incorporation of immigrants.

    Full Text Available Cardiogenic shock (CS in the setting of an ST-segment elevation myocardial infarction (STEMI is a severe complication and constitutes one of the principal causes of death associated with this condition. The aim of this study was to describe the clinical characteristics, treatment strategies and hospital outcome of CS associated with STEMI in Argentina. The Argentine Registry of Cardiogenic Shock (ReNA-Shock was a prospective and multicenter registry of consecutive patients with CS hospitalized in 64 centers in Argentina between July 2013 and May 2015. Only those with ST-segment elevation myocardial infarction (STEMI were selected for this analysis. Of the 165 patients included in the ReNa-Shock registry, 124 presented STEMI. Median age was 64 years (IQR 25-75: 56.5-75 and 67% were men; median time from symptom onset to admission was 240 minutes (IQR 25-75: 132-720. 63% of the cases presented CS at admission. Eighty-seven percent underwent reperfusion therapy: 80% primary percutaneous intervention with a median door-to-balloon time of 110 minutes (IQR 25-75: 62-184. Inotropic agents were used in 96%; 79% required mechanical ventilation; a Swan Ganz catheter was inserted in 47% and 35% required intra-aortic balloon pumping. Most patients (59% presented multivessel disease (MV. Hospital mortality was 54%. Multivariate analysis identified that time from symptom onset to admission (> 240 min was the only independent predictor of mortality (OR: 3.04; CI 95%: 1.18-7.9. Despite using treatment strategies currently available, morbidity and mortality of STEMI complicated with CS remains high.

  9. If F(ST) does not measure neutral genetic differentiation, then comparing it with Q(ST) is misleading. Or is it?

    2011-05-01

    The comparison between neutral genetic differentiation (F(ST) ) and quantitative genetic differentiation (Q(ST) ) is commonly used to test for signatures of selection in population divergence. However, there is an ongoing discussion about what F(ST) actually measures, even resulting in some alternative metrics to express neutral genetic differentiation. If there is a problem with F(ST) , this could have repercussions for its comparison with Q(ST) as well. We show that as the mutation rate of the neutral marker increases, F(ST) decreases: a higher within-population heterozygosity (He) yields a lower F(ST) value. However, the same is true for Q(ST) : a higher mutation rate for the underlying QTL also results in a lower Q(ST) estimate. The effect of mutation rate is equivalent in Q(ST) and F(ST) . Hence, the comparison between Q(ST) and F(ST) remains valid, if one uses neutral markers whose mutation rates are not too high compared to those of quantitative traits. Usage of highly variable neutral markers such as hypervariable microsatellites can lead to serious biases and the incorrect inference that divergent selection has acted on populations. Much of the discussion on F(ST) seems to stem from the misunderstanding that it measures the differentiation of populations, whereas it actually measures the fixation of alleles. In their capacity as measures of population differentiation, Hedrick's G'(ST) and Jost's D reach their maximum value of 1 when populations do not share alleles even when there remains variation within populations, which invalidates them for comparisons with Q(ST) . © 2011 Blackwell Publishing Ltd.

    This is an encore presentation of what was presented at the 2012 AGU International Conference. It was entitled: 'The Importance of Water Conservation in the 21st Century.' The poster presentation, however, has been redesigned and reorganized with new, revised perspectives. The importance of water conservation principles has been emphasized. The population of United States has more than doubled over the past 50 years. The need for water however, has tripled. The EPA estimates that more than 36 states face water shortage during the forthcoming years. The EPA has prepared a plan for achieving environmental and energy performance. This will be coupled with leadership and accountability. Carbon neutrality is also of prime importance. The objective is to focus on six important, essential areas. 1. Efficient use of already available energy resources. 2. Intelligent water consumption and focusing on water conservation. 3. Expand the use of renewable energy resources. 4. Explore innovative transportation systems and methodologies. 5. Change building codes and promote high performance sustainable buildings. 6. Focus on developing creative environment management systems. Greenhouse gases such as carbon dioxide occur naturally in the atmosphere. Carbon dioxide is also emitted to the atmosphere through a variety of natural processes and also some human activities. However, fluorinated gases are emitted to the atmosphere solely through human activities, because they are created by humans. It is very important to observe that water conservation is probably the most cost-effective way to reduce our demand for water. Furthermore, it is certainly environmentally justifiable. The Environmental Protection Agency has a plan called E2PLAN. It is EPA's plan for achieving energy and environmental performance, leadership, accountability, and carbon neutrality. In June 2011, the EPA published a comprehensive, multi-year planning document called Strategic Sustainability Performance Plan. The

    Full Text Available This work comments in particular on studies dealing with the church of St. Sofia in Ohrid. Among them are the monographs of two authors, Barbara Maria Schellewald (Die Arhitektur der Sophien Kirchen in Ohrid, Bon 1986 and Boris Čipan (Sveta Sofija, katedralen hram na ohridskata arhiepiskopija, Skopje 1995. Special attention is devoted to the typological interpretation of St. Sofia, to its initial design as a triple-nave basilica with a dome at the centre. Insightful descriptions are given about the older monuments in the Byzantine capital, Constantinople. Special attention is paid to the external architectonic workmanship. The western façade of St. Sofia demonstrates the features of Late Byzantine architecture, while the eastern façade directly reveals the triple-nave spatial design. That is why this article on St. Sofia contains sketches of the western and the eastern façades, illustrating the features of its architectonic specificities. On the whole, the author presents St. Sofia in Ohrid as a unique work of architecture of the Byzantine region. .

    2009-06-01

    The St. Petersburg Paradox is a famous economic and philosophical puzzle that has generated numerous conflicting explanations. To shed empirical light on this phenomenon, we examined subjects' bids for one St. Petersburg gamble with a real monetary payment. We found that bids were typically lower than twice the smallest payoff, and thus much lower than is generally supposed. We also examined bids offered for several hypothetical variants of the St. Petersburg Paradox. We found that bids were weakly affected by truncating the gamble, were strongly affected by repeats of the gamble, and depended linearly on the initial "seed" value of the gamble. One explanation, which we call the median heuristic , strongly predicts these data. Subjects following this strategy evaluate a gamble as if they were taking the median rather than the mean of the payoff distribution. Finally, we argue that the distribution of outcomes embodied in the St. Petersburg paradox is so divergent from the Gaussian form that the statistical mean is a poor estimator of expected value, so that the expected value of the St. Petersburg gamble is undefined. These results suggest that this classic paradox has a straightforward explanation rooted in the use of a statistical heuristic.

    21st birthday celebrations are among the highest risks for alcohol use throughout emerging adulthood and celebrants often experience a range of alcohol-related consequences. The present research considered what happens when drinking games are paired with an already high-risk event (i.e., 21st birthday celebrations) and how drinking games compare with other contextual factors on 21st birthdays. Approximately four days after turning 21, 1124 college students (55% women) completed an online survey assessing alcohol use and related consequences experienced during their birthday celebrations. Participants were also asked whether drinking games and other contextual factors were associated with their celebrations. Overall, 18% of participants reported playing drinking games during their 21st birthday celebrations. These individuals reported consuming more alcohol, had higher estimated BACs, and experienced more negative consequences than those who did not play drinking games. The association between playing drinking games and alcohol use and negative consequences was stronger for men. The effect of drinking games on negative consequences was mediated through elevated BAC levels. Receiving bar specials, having drinks purchased, playing drinking games, and loud music were uniquely and significantly associated with all alcohol outcomes. Together, these results suggest that drinking games are part of a larger context of risk contributing to extreme drinking on 21st birthdays. Furthermore, these results will help to facilitate interventions that are more individually tailored to target specific contextual risks, behaviors, and events.

    The article is devoted to assessment of the role of high-rise buildings in the St. Petersburg historic city's ensemble. Features of formation of city architectural look, the conditions of city typical silhouette's appearance which is characterized by the contrast of a small number of high-rise structures with a low horizontal mass building are observed. The consequences of the emergence of a significant number of great height buildings, the silhouette of which conflicts with the traditional St. Petersburg landscape's compositional principles, are analyzed. The economic reasons of high-rise construction of residential and office buildings are given. The conclusions about the prospects of St. Petersburg high-rise construction in the light of city-building and economic factors are made.

    The critical issues of the poloidal systems for the ARIES-ST design have been presented in this paper. Because of the large plasma current and the need of highly shaped plasmas, the poloidal field (PF) coils should be located inside the toroidal field in order to reduce their current. Even then, the divertor coils carry large currents. The ARIES-ST PF coils are superconducting using the internally cooled cable-in-conduit conductor. The peak self field in the divertor coils is about 15 T and the highest field in the non-divertor coils is about 6 T. The PF magnets have built-in margins that are sufficient to survive disruptions without quenching. The costing study indicates that the specific cost of the PF system is $80/kg. Detailed design and trade-off studies of ARIES-ST are presented and remaining R and D issues are identified

    Full Text Available Introduction. Acute myocardial infarction is life-threatening. A cardiac troponin rise accompanied by typical symptoms, ST elevation or depression is diagnostic of acute myocardial infarction. Here, we report an unusual case of a female who was admitted with chest pain. However, she did not present with a typical profile of an acute myocardial infarction patient. Case Presentation. A 66-year-old Han nationality female presented with chest pain. The electrocardiogram (ECG revealed arched ST segment elevations and troponin was elevated. However, the coronary angiography showed a normal coronary arterial system. Thyroid function tests showed that this patient had severe hyperthyroidism. Conclusion. Our case highlights the possibility that hyperthyroidism may cause a large area of myocardium injury and ECG ST segment elevation. We suggest routine thyroid function testing in patients with chest pain.

  19. Construction: first of St. Lucie unit 2 successes

    International Nuclear Information System (INIS)

    Conway, W.F.

    1989-01-01

    The Nuclear Regulatory Commission (NRC) granted a full power operating license for St. Lucie Unit 2 on June 10, 1983, just six years after construction began. The industry average for nuclear power plant construction during this time was approximately ten years. The rate of completion had a positive effect on the cost of the facility. The price of the unit was $1.42 billion as compared to the $2 billion to $5 billion range experienced by other utilities for nuclear plants. These accomplishments were not serendipitous but the results of management techniques and personnel attitudes involved in the construction of the unit. More importantly, many of these same techniques and attitudes have now become part of a quality improvement program at St Lucie and are reflected in its performance indicators. This paper analyzes the construction success of St Lucie Unit 2 and demonstrates that excellent performance in the construction phase can be carried over to the operation of a facility

  20. Geology of St. John, U.S. Virgin Islands

    Rankin, Douglas W.

    2002-01-01

    The rocks of St. John, which is located near the eastern end of the Greater Antilles and near the northeastern corner of the Caribbean plate, consist of Cretaceous basalt, andesite, keratophyre, their volcaniclastic and hypabyssal intrusive equivalents, and minor calcareous rocks and chert. These rocks were intruded by Tertiary mafic dikes and tonalitic plutons. The oldest rocks formed in an extensional oceanic environment characterized by abundant keratophyre and sheeted dikes. Subduction-related volcanism of the east-west-trending marine Greater Antilles volcanic arc began on St. John near the transition between the Early and Late Cretaceous. South-directed compression, probably caused by the initial collision between the Greater Antilles arc of the Caribbean plate and the Bahama platform of the North American plate, deformed the Cretaceous strata into east-west-trending folds with axial-plane cleavage. Late Eocene tonalitic intrusions, part of the Greater Antilles arc magmatism, produced a contact aureole that is as much as two kilometers wide and that partly annealed the axial-plane cleavage. East-west compression, possibly related to the relative eastward transport of the Caribbean plate in response to the beginning of spreading at the Cayman Trough, produced long-wavelength, low-amplitude folds whose axes plunge gently north and warp the earlier folds. A broad north-plunging syncline-anticline pair occupies most of St. John. The last tectonic event affecting St. John is recorded by a series of post-late Eocene sinistral strike-slip faults related to the early stages of spreading at the Cayman Trough spreading center and sinistral strike-slip accommodation near the northern border of the Caribbean plate. Central St. John is occupied by a rhomb horst bounded by two of these sinistral faults. Unlike other parts of the Greater Antilles, evidence for recent tectonic movement has not been observed on St. John.

  1. El cigarrillo: implicaciones para la salud

    Manuel Antonio Ballén

    2006-07-01

    Full Text Available Antecedentes. El consumo de cigarrillo, según cálculos de la Organización Mundial de la Salud (OMS, es la causa de por lo menos cuatro millones de muertes al año. Las consecuencias de fumar cigarrillo van desde cambios fisiopatológicos en los sistemas respiratorio, cardiovascular y digestivo, hasta trastornos mentales asociados a la dependencia a la nicotina. Objetivo. Realizar una revisión narrativa de la literatura médica mostrando los efectos del consumo de cigarrillo sobre la salud física y mental en los fumadores activos y pasivos. Material y métodos. El artículo se basa en la revisión de artículos a través de la base de datos del MEDLINE y de la biblioteca Virtual de la OMS. Se emplearon en la búsqueda las palabras clave "Cigarette Smoke", "Cancer AND smoke", "COPD AND smoke", "Nicotine Dependence". Se escogieron artículos y libros publicados en idioma inglés entre los años 1994 y 2006, realizando una lectura crítica (análisis de posibles conflictos de interés y errores de diseño. Conclusión. El humo del cigarrillo contiene partículas potencialmente peligrosas para la salud de quien está expuesto a ellas. De este modo, fumar cigarrillo se convierte en un factor etiológico común a muchos tipos de cáncer. Además los componentes del cigarrillo están relacionados con el desarrollo de otros estados patológicos (enfermedad cardiovascular y enfermedad pulmonar obstructiva crónica. La nicotina, uno de sus componentes, es un potente agente adictivo. Todo esto en su conjunto hace del cigarrillo un importante problema de salud pública.

    Full Text Available El presente trabajo tiene por objeto revisar los aspectos teóricos y los estudios realizados en México que sugieren la existencia de la deficiencia moderada de zinc en niños de población rural, así como algunas de las consecuencias de dicha deficiencia en la salud. El zinc es un nutrimento indispensable para el organismo de los humanos y juega un papel importante en una serie de procesos metabólicos: participa en el sitio catalítico de varios sistemas enzimáticos; participa como ion estructural en membranas biológicas, y guarda una estrecha relación con la síntesis de proteínas, entre otras cosas. Es por esto que la deficiencia de zinc está asociada con consecuencias importantes en la salud y la funcionalidad de los individuos, especialmente durante las primeras etapas de la vida. De relevancia para México es la existencia de una deficiencia moderada de zinc en los niños y las consecuencias que ésta pueda tener en la salud de los mismos. Los estudios realizados sugieren que la deficiencia moderada de zinc se presenta asociada con la ingestión de dietas basadas en alimentos de origen vegetal, las cuales contienen cantidades importantes de inhibidores de la absorción de zinc. Este tipo de dietas se consume habitualmente en las zonas rurales y en la población marginal de las ciudades en el país. Entre las consecuencias más importantes de esta deficiencia se encontró un aumento en la presencia de enfermedades infecciosas, especialmente de diarrea, y posibles alteraciones en el desarrollo de la capacidad cognoscitiva.

    2017-12-01

    Although smoking declines in the United States, the prevalence of male adolescent smokeless tobacco (ST; moist snuff and chewing tobacco) use remains unchanged. ST product characteristics, such as flavoring, packaging, and branding, could influence adolescents' ST initiation and continued use. This qualitative study examines the potential role of product characteristics in shaping ST-related perceptions and behaviors among rural adolescent males. Semi-structured individual interviews were conducted at three California rural high schools. ST users were asked about their experiences and perceptions related to product characteristics. Interviews were transcribed, coded, and analyzed using a general inductive approach. Participants associated flavored ST with appealing non-tobacco products, such as chewing gum and alcohol. Availability of different varieties and flavors stimulated interest and curiosity in sampling or switching between ST products. Time-limited promotional flavors and packaging also enhanced product appeal. Adolescent ST users preferred certain brands based on perceived brand features and perceived nicotine content, associating higher-strength brands as better suited for experienced ST users. Brand preferences frequently reflected perceived ST brand popularity within peer groups. Based on these observations, potential ST regulation and health education campaigns to address misconceptions about ST characteristics could influence adolescents' ST-related perceptions and reduce ST use among this vulnerable population. © The Author 2017.

El abordaje del diagnóstico genético en familias con PAF seguidas previamente en la consulta de digestivo, ha permitido poner de manifiesto tanto las ventajas como los inconvenientes de esta forma de acercarnos a la enfermedad y a los pacientes. La revelación de los resultados de la prueba genética comporta importantes problemas en la práctica clínica, que afectan tanto al ámbito sanitario, como al ético y legal, además de las implicaciones familiares, laborales y sociales que el conocimiento del status genético puede tener para el paciente. El análisis genético es poco frecuente en la práctica clínica habitual, lo que conlleva errores tanto en la interpretación de los resultados obtenidos como durante el proceso del consejo genético. Son necesarias unidades multidisciplinares especializadas en el manejo de pacientes con PAF, en las cuales se realice un análisis y un consejo genético adecuado, permitiendo así una atención personalizada. La creación de registros de PAF y la protocolización de este proceso sanitario debería optimizar el manejo de estos pacientes y sus familias.

    In conclusion, physical medicine and rehabilitation in the 21st century will be: new, exciting technologies, different patient populations, different practice settings, fewer PM&R residents, and more physician assistants, all operating under a universal access, single payer, Canadian-style health care system. I began my presentation with a quote from Yogi Berra. I'll close by paraphrasing the immortal words of Charles Dickens in the opening lines of A Tale Of Two Cities. PM&R in the 21st century will be "the best of times, the worst of times, the epoch of belief, the epoch of incredulity."

    The construction of the steel liners for the Fort St. Vrain prestressed concrete reactor vessel presented many unique problems for which techniques were developed to satisfy the rigid specification requirements. The PCRV cavity liner was fabricated from 1.9cm carbon steel plate. The liners were partially fabricated by Pittsburgh-Des Moines Steel Company at their Pittsburgh manufacturing facility. The liners were then shipped by rail to within approximately five miles of the jobsite and then trucked the remaining distance. The construction techniques, dimensional control, concrete support and testing utilized on the Fort St. Vrain project are presented in detail and demonstrate the flexibility of the PCRV for field construction.

    In 2007, the monastery St. Ottilien near Munich (Federal Republic of Germany) registered an annual emission of 2,500 tonnes of CO{sub 2}. The associated costs and environmental concerns disposed the monastery to a reduction in the consumption of fossil fuels (about 700,000 liters of heating oil per year) by 90 % by means of a variety of measures. An extensive program of thermal insulation was carried out, and a highly efficient heating system for the restoration of 45 buildings was installed. A thermographic analysis of the existing buildings resulted in an energy-efficient renovation. Efforts have been made for thermal insulation. Windows were replaced. The heating sysem and steam production were optimized. A central power supply with two wood pellet boilers and a combined heat and power plant based on biogas were installed. Thus 90 % of heat supply and 100 % of the power generation of the monastery were covered. Thus, the CO{sub 2} emissions were reduced to 500 tons in 2009, and to 250 tons in 2010.

    Reciprocal ST-depression in the electrocardiograms (ECGs) of patients with ST-elevation myocardial infarction (STEMI) results from either true ischemia at a distance via collateral circulation diverting blood to the infarcted region or an electrical phenomenon that results from a mirror reflection of ST-elevation. We aimed to identify the role of reciprocal ECG changes in predicting collateral circulation to the infarcted area determined angiographically. In a retrospective study, ECG and angiography of 53 STEMI patients admitted to SUNY Upstate Medical University in 2014 were reviewed independently by experts blinded to the results of ECG and coronary angiography. Reciprocal changes (RC) in ECG were present in 41 patients (77%) and on angiography, 14 patients (26%) exhibited collateral vessels to the ischemic areas. No correlation was found between the presence of RC and collateral circulation (P = 0.384), or between the depth of reciprocal ST-depression and the degree of the collateral circulation (P = 0.195). However, 84% of patients without collaterals exhibited resolution of RC after successful percutaneous coronary intervention (PCI) (P = 0.036), suggesting that the ST depressions that resolved after reperfusion were directly caused by the culprit vessel. Patients without RC presented late after symptom onset (9.25 versus 3.83 hours, P = 0.004), also suggesting time related resolution. RC had no relation to or predictive value for collaterals on angiography. Among late presenting patients, RC were less frequent. Thus, reciprocal ST-depression may represent subendocardial ischemia from the primary coronary event or simply an electrical phenomenon, rather than ischemia at distance from impaired collateral circulation.

    The U.S. Department of Energy (DOE) national laboratories use their expertise in nuclear science and technology (S&T) to support a robust national nuclear S&T enterprise from the ground up. Traditional academic programs do not provide all the elements necessary to develop this expertise, so the DOE has initiated a number of supplemental programs to develop and support the nuclear S&T workforce pipeline. This document catalogs existing workforce development programs that are supported by a number of DOE offices (such as the Offices of Nuclear Energy, Science, Energy Efficiency, and Environmental Management), and by the National Nuclear Security Administration (NNSA) and the Naval Reactor Program. Workforce development programs in nuclear S&T administered through the Department of Homeland Security, the Nuclear Regulatory Commission, and the Department of Defense are also included. The information about these programs, which is cataloged below, is drawn from the program websites. Some programs, such as the Minority Serving Institutes Partnership Programs (MSIPPs) are available through more than one DOE office, so they appear in more than one section of this document.

  18. A 3000 yr paleostorm record from St. Catherines Island, Georgia

    2017-09-01

    Tropical cyclones (hurricanes in the northern hemisphere) are amongst the most devastating of the world's natural disasters and cause billions of dollars in damage every year. Data on the likelihood of a coastal site being struck by a major hurricane strike can potentially aid in planning and mitigation efforts that could save money and lives. However, forecasting requires data that are currently insufficient for the Georgia Bight. This study provides information to enhance the paleohurricane record by analysis of a 467 cm thick vibracore raised from St. Catherines Island, GA. Sediment geochemistry and foraminiferal assemblages indicate deposits attributable to seven paleohurricane events, five of which were likely major hurricanes when they made landfall on St. Catherines. Magnitudes were estimated by comparison to the overwash deposit left by ;The Sea Islands hurricane of 1893;, a major hurricane recorded by the recent sediment of St. Catherines Island. The St. Catherines record also shows a change in the activity levels on the Georgia coast with two distinct activity regimes over the past 3000 years.

    2016-09-01

    Full Text Available The paper is an attempt to summarize the interaction of the two largest schools of psychology in Russia: the psychological schools of Moscow and St. Petersburg. The paper is a sketch dedicated to the 50th anniversary of the psychological faculties of Moscow and St. Petersburg, and should not be appreciated as a historical treatise. Tense ties between the psychological schools, that originate in the distant past, have gone through different historical stages. Slavophilevs Westernizer traditions affected the initial difference in these schoolsemerging into the opposition: either the human being is studied entirety with his/her vast subjective experience, but losing the reliability of our statements (peculiarity of Moscow school, or we study the human being accurately using objective methods, but losing the integrity of our ideas (peculiarity of St.-Petersburg school. Both psychological schools, having gone through the ups and downs, have retained their identity and their emphasis on research. Moscow scholars in their studies are aimed to larger issues and still rely on large-scale Vygotsky-Leontiev approach. Scholars of St.-Petersburgtouch upon more specific issues using empirical methods, but still continue with nostalgia and hope making plans about creating a common concept of human individual according to Ananiev. Nowadays between the two schools there is no opposition, but only one mutual love.

    Full Text Available Abstract During routinely screening (50.000 milk samples on an annual basis 14 MRSA ST398 strains were identified in the period of January 2008 to September 2008 in 14 different dairy herds located in the provinces Overijssel and Gelderland, The Netherlands. Molecular analysis was performed by Cfr9I PFGE, ST398-specific diagnostic PCR, spa typing, SCCmec typing and Panton-Valentine Leukocidin (PVL gene PCR. The molecular analyses of 14 MRSA (one MRSA strain per herd strains revealed that all strains belong to ST398 with 3 closely related spa types (t011, t108 and t889, all commonly found in pigs and carry 2 different SCCmec types, IVa and V. All MRSA strains were resistant to two or more classes of antibiotics and also PVL negative. The majority of farms (n = 9, 64% harboured combined livestock with both cows and pigs present. Our study contributes to the growing evidence that MRSA ST398 is transmitted among various animal species and can be considered as an etiological agent of mastitis in dairy cows.

    1994-01-01

    SAES metal getter material St 198 was chosen for glovebox stripper tests to evaluate its effectiveness of removing tritium from a nitrogen atmosphere. The St 198 material is unique from a number of other metal hydride-based getter materials in that it is relatively inert to nitrogen and can thus be used in nitrogen glovebox atmospheres. Six tritium stripper experiments which mock-up the use of a SAES St 198 stripper bed for a full-scale (10,500 liter) nitrogen glovebox have been completed. Experiments consisted of a release of small quantity of protium/deuterium spiked with tritium which were scaled to simulate tritium releases of 0.1 g., 1.0 g., and 10 g. into the glovebox. The tritium spike allows detection using tritium ion chambers. The St 198 stripper system produced a reduction in tritium activity of approximately two orders of magnitude in 24 hours (6--8 atmosphere turn-overs) of stripper operation

    The interleukin-1 receptor-like protein ST2 exists in both membrane-bound (ST2L) and soluble form (sST2). ST2L has been found to play an important regulatory role in Th2-type immune response, but the function of soluble form of ST2 remains to be elucidated. In this study, we report the protective effect of soluble ST2 on warm hepatic ischemia/reperfusion injury. We constructed a eukaryotic expression plasmid, psST2-Fc, which expresses functional murine soluble ST2-human IgG1 Fc (sST2-Fc) fusion protein. The liver damage after ischemia/reperfusion was significantly attenuated by the expression of this plasmid in vivo. sST2-Fc remarkably inhibited the activation of Kupffer cells and the production of proinflammatory mediators TNF-α and IL-6. Furthermore, the levels of TLR4 mRNA and the nuclear translocation of NF-κB were also suppressed by pretreatment with sST2-Fc. These results thus identified soluble ST2 as a negative regulator in hepatic I/R injury, possibly via ST2-TLR4 pathway

  17. Transformations in Air Transportation Systems For the 21st Century

    Holmes, Bruce J.

    2004-01-01

    Globally, our transportation systems face increasingly discomforting realities: certain of the legacy air and ground infrastructures of the 20th century will not satisfy our 21st century mobility needs. The consequence of inaction is diminished quality of life and economic opportunity for those nations unable to transform from the 20th to 21st century systems. Clearly, new thinking is required regarding business models that cater to consumers value of time, airspace architectures that enable those new business models, and technology strategies for innovating at the system-of-networks level. This lecture proposes a structured way of thinking about transformation from the legacy systems of the 20th century toward new systems for the 21st century. The comparison and contrast between the legacy systems of the 20th century and the transformed systems of the 21st century provides insights into the structure of transformation of air transportation. Where the legacy systems tend to be analog (versus digital), centralized (versus distributed), and scheduled (versus on-demand) for example, transformed 21st century systems become capable of scalability through technological, business, and policy innovations. Where air mobility in our legacy systems of the 20th century brought economic opportunity and quality of life to large service markets, transformed air mobility of the 21st century becomes more equitable available to ever-thinner and widely distributed populations. Several technological developments in the traditional aircraft disciplines as well as in communication, navigation, surveillance and information systems create new foundations for 21st thinking about air transportation. One of the technological developments of importance arises from complexity science and modern network theory. Scale-free (i.e., scalable) networks represent a promising concept space for modeling airspace system architectures, and for assessing network performance in terms of robustness

  18. Environmental Assessment on the leasing of the Strategic Petroleum Reserve, St. James Terminal, St. James Parish, Louisiana

    1995-01-01

    The US Department of Energy (DOE) proposes to lease the Strategic Petroleum Reserve`s (SPR) St. James Terminal to private industry. The St. James Terminal consists of six storage tanks, a pumping station, two maine docks and ancillary facilities. DOE believes that the St. James Terminal presents an opportunity to establish a government- industry arrangement that could more effectively use this asset to serve the nations`s oil distribution needs, reduce the operational cost of the SPR, and provide a source of revenue for the Government. DOE solicited interest in leasing its distribution facilities in a notice published March 16, 1994. In response, industry has expressed interest in leasing the St. James Terminal, as well as several DOE pipelines, to enhance the operation of its own facilities or to avoid having to construct new ones. Under such a lease, industry use would be subordinate to DOE use in the event of a national energy emergency. This Environmental Assessment describes the proposed leasing operation, its alternatives, and potential environmental impacts. Based on this analyses, DOE has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) OF 1969 and has issued the Finding of No Significant Impact (FONSI).

    Many universities all over the world have now established hands-on education programs based on CubeSats. These small and cheap platforms are becoming more and more attractive also for other-than-educational missions, such as technology demonstration, science applications, and Earth observation. This new paradigm requires the development of adequate technology to increase CubeSat performance and mission reliability, because educationally-driven missions have often failed. In 2013 the ESA Education Office launched the Fly Your Satellite! Programme which aims at increasing CubeSat mission reliability through several actions: to improve design implementation, to define best practices for conducting the verification process, and to make the CubeSat community aware of the importance of verification. Within this framework, the CubeSat team at Politecnico di Torino developed the e-st@r-II CubeSat as follow-on of the e-st@r-I satellite, launched in 2012 on the VEGA Maiden Flight. E-st@r-I and e-st@r-II are both 1U satellites with educational and technology demonstration objectives: to give hands-on experience to university students and to test an active attitude determination and control system based on inertial and magnetic measurements with magnetic actuation. This paper describes the know-how gained thanks to the e-st@r-I mission, and how this heritage has been translated into the improvement of the new CubeSat in several areas and lifecycle phases. The CubeSat design has been reviewed to reduce the complexity of the assembly procedure and to deal with possible failures of the on-board computer, for example re-coding the software in the communications subsystem. New procedures have been designed and assessed for the verification campaign accordingly to ECSS rules and with the support of ESA specialists. Different operative modes have been implemented to handle some anomalies observed during the operations of the first satellite. A new version of the on-board software is
