    2013-01-01

    En investigaciones previas sobre el acogimiento familiar y la adopción en Ayacucho, se ha podido descubrir cómo los ayacuchanos adquieren y producen relaciones sociales. Mientras negocian creativamente los discursos y espacios construidos simultáneamente por instituciones, comunidades, y estructuras sociales, van adquiriendo nuevas formas de relacionarse. Este artículo discute el proceso opuesto: el deshacerse de relaciones de parentesco, y el proceso social del abandono o alejamiento. Cuando se aleja a una persona de su familia o su comunidad, los que se quedan en ella llegan a entenderse como ciertos tipos de personas. En los estudios de caso discutidos aquí, recopilados a través de una detallada y cuidadosa observación participante y de entrevistas etnográficas grabadas entre 2001 y 2007, se puede ver cómo, después de un alejamiento social, los individuos que alejan se reinterpretan como sujetos que se encuentran superándose o volviéndose modernos, o bien sacrificándose.

    Resumen: En este artículo presentamos el proyecto de capacitación llevado a cabo en comunidades de la sierra y costa de Oaxaca, México, desde 1991, por el Centro de Capacitación Integral para Promotores Comunitarios (CECIPROC). La decisión de hacer este trabajo en Oaxaca responde a que ese estado ocupa uno de los primeros lugares de marginación y de desnutrición en menores de 5 años. El objetivo es describir un modelo de capacitación y compartir parte de las experiencias derivadas, tanto del modelo como del trabajo realizado en las distintas áreas (nutrición y alimentación, salud comunitaria, ecología y etnobotánica, y educación y organización), por promotores mujeres y hombres en sus comunidades. La experiencia obtenida en 24 años muestra la factibilidad técnica y social del proyecto en el ámbito de la salud, el reconocimiento social del proyecto del CECIPROC como un organismo civil que ha aportado alternativas como solución a la problemática de salud, el hacer suyo el proyecto por algunos promotores y los diferentes obstáculos a los que se ha enfrentado. Enfatizamos el hecho de que la situación socioeconómica y política prevaleciente en el estado de Oaxaca es una limitante para el buen desarrollo de los programas colectivos de salud, e insistimos en la necesidad de compartir nuestras experiencias para que puedan ser utilizadas en la planificación y ejecución de otros proyectos.

    El capital social supone importantes inversiones materiales, simbólicas y de esfuerzos. Conocer el capital social de una comunidad puede facilitar la comprensión del beneficio de las relaciones comunitarias para la promoción de salud. Con el objetivo de reconocer los componentes del capital social de padres de escolares atendiendo una escuela en una zona vulnerable de la ciudad de Córdoba, Argentina, indagamos a través de grupos focales acerca de elementos esenciales del capital social. La asintonía socio-cultural entre los pobladores originarios y los reubicados, la estigmatización policial y el clientelismo político han generado desconfianza del uno hacia el otro en diferentes aspectos convivenciales, siendo la familia la única red de apoyo. La escuela se reconoce como espacio adonde la gente espontáneamente se organiza para invertir en redes sociales, presentándose así con potencialidad para la promoción de conductas saludables, por el lugar simbólico que ocupa para los padres.

    Klijn, Frans; Witte, Jan-Philip M.

    Résumé En écologie végétale, le site est un concept central. Un site, c'est l'endroit où une espèce végétale ou une communauté de plantes se développe le site assure un ensemble de conditions dans lesquelles elles vivent. Dans un matériau homogène à l'origine, l'écoulement gravitaire d'une nappe influence les conditions du site par l'intermédiaire de la distribution spatiale des nutriments et d'autres composés chimiques associés. Les remontées d'eau peuvent tout spécialement produire et maintenir les conditions du site essentielles pour différentes espèces et communautés de plantes relativement rares. Les écologues ont porté une attention accrue à ces remontées d'eau, en sorte qu'une coopération avec les hydrologues en a résulté, avec l'émergence d'une discipline propre, l'éco-hydrologie, à la limite des deux domaines scientifiques et liée au concept de site. Aux Pays-Bas, une classification des types d'eau, basée sur l'histoire de l'eau souterraine à proximité de la surface, a été mise en oeuvre pour constituer une base nationale de données géographiques sur les remontées d'eau d'intérêt écologique. Des analyses des correspondances des données de cette base, portant sur l'existence de certaines espèces de plantes, montrent que dans les sols sableux pauvres du Pléistocène la remontée d'eau explique très bien la présence de certaines espèces et communautés, alors que, dans les plaines fluviales et les régions de polders à sols argileux riches, l'influence de la remontée d'eau est masquée par l'importance des caractéristiques des sols. En conclusion donc, certaines espèces de plantes peuvent être utilisées comme des indicateurs de la remontée d'eau dans des diagnostiques et des levés de terrain rapides, mais à condition de prendre en permanence des précautions sur les limites de l'approche. Resumen En ecología botánica un concepto de gran importancia es el de emplazamiento, definido como el lugar que proporciona unas condiciones de vida adecuadas que permiten el crecimiento de una especie o una comunidad botánica. En un material inicialmente homogéneo, el flujo subterráneo gravífico influencia las condiciones del emplazamiento variando la distribución espacial de los nutrientes y de otros agentes químicos relevantes. En especial, el flujo ascendente puede producir y mantener una serie de condiciones que son esenciales para algunas especies y comunidades de plantas relativamente raras. La especial atención hacia este fenómeno ha dado lugar a una cooperación entre ecologistas e hidrogeólogos y a la aparición de una nueva disciplina - eco-hidrología -, en la frontera de los dos campos científicos. En Holanda, se ha usado una clasificación sencilla de tipos de agua para crear una base de datos, a nivel nacional, de lugares donde la presencia de flujos ascendentes pueda ser de interés ecológico. El análisis de correspondencias entre esta base de datos y los tipos de plantas existentes muestra que en los suelos arenosos pobres del Pleistoceno los flujos ascendentes explican la presencia de algunas especies y comunidades de plantas. Por el contrario, en las llanuras fluviales y pólders, con suelos más arcillosos, la influencia de estos flujos es despreciable frente a la relativa a las propias características de los suelos. Se concluye que las especies botánicas se pueden usar como indicadores de la presencia de flujo ascendente sólo en campañas preliminares, pero que el método presenta grandes limitaciones para su extensión a casos generales.

    RESUMEN Introducción Las infecciones del tracto urinario (ITU) son frecuentes en la comunidad. Sin embargo, la información de aislamientos resistentes en este contexto es limitada en Latinoamérica. Este estudio tiene como objetivo determinar la prevalencia y los factores de riesgo asociados con ITU de inicio en la comunidad (ITU-IC) causadas por Escherichia coli productor de betalactamasas de espectro extendido (BLEE) en Colombia. Materiales y métodos Entre agosto y diciembre de 2011 se realizó un estudio de casos y controles en 3 instituciones de salud de tercer nivel en Colombia. Se invitó a participar a todos los pacientes admitidos a urgencias con diagnóstico probable de ITU-IC, y se les pidió una muestra de orina. En los aislamien-tos de E. coli se realizaron pruebas confirmatorias para BLEE, susceptibilidad antibiótica, caracterización molecular (PCR en tiempo real para genes bla, repetitive element palindromic PCR [rep-PCR], multilocus sequence typing [MLST] y factores de virulencia por PCR). Se obtuvo información clínica y epidemiológica, y posteriormente se realizó el análisis estadístico. Resultados De los 2.124 pacientes seleccionados, 629 tuvieron un urocultivo positivo, en 431 de estos se aisló E. coli, 54 fueron positivos para BLEE y 29 correspondieron a CTX-M-15. La mayoría de los aislamientos de E. coli productor de BLEE fueron sensibles a ertapenem, fosfomicina y amikacina. La ITU complicada se asoció fuertemente con infecciones por E. coli productor de BLEE (OR = 3,89; IC 95%: 1,10–13,89; p = 0,03). E. coli productor de CTX-M-15 mostró 10 electroferotipos diferentes; de estos, el 65% correspondieron al ST131. La mayoría de estos aislamientos tuvieron 8 de los 9 factores de virulencia analizados. Discusión E. coli portador del gen blaCTX-M-15 asociado al ST131 sigue siendo frecuente en Colombia. La presencia de ITU-IC complicada aumenta el riesgo de tener E. coli productor de BLEE, lo cual debe tenerse en cuenta para ofrecer una terapia empírica adecuada. PMID:26774256

    Resumen VIH/SIDA es una pandemia que afecta a hombres, mujeres y niños, pero que presenta una tendencia hacia la feminización, afectando especialmente a mujeres jóvenes. Su consecuencia es el aumento de la transmisión vertical, durante el embarazo, parto o lactancia materna. Este estudio bibliográfico describe la relación entre VIH/SIDA y lactancia materna, explicitando factores que influyen en la elección de la modalidad de alimentación de madres viviendo con VIH/SIDA. Se describen causas de morbimortalidad infantil asociada y recomendaciones internacionales de lactancia en mujeres con VIH/SIDA. En un mundo globalizado con constantes migraciones poblacionales, estos resultados representan un llamado de atención para profesionales de salud quienes deben considerar factores sociales que influenciarán la toma de decisión de madres viviendo con VIH/SIDA al escoger la modalidad de lactancia. No sólo basta conocer el riesgo de transmisión vertical, sino que se debe tomar conciencia de aquellos factores dinámicos y específicos de cada comunidad. PMID:20046815

    A fines de 1991, en una revista de educación en ciencias, José L. Sérsic reflexionaba acerca de los problemas que enfrentaría la enseñanza de los conocimientos astronómicos en nuestro país, en los umbrales del Siglo XXI. Entonces postulaba como un objetivo mínimo, que los jóvenes deberían mostrar signos claros de que se hallan astronómicamente alfabetizados. Era el año en que se realizaba por primera vez una Asamblea General de I.A.U. en Buenos Aires, una oportunidad de singulares características para la comunidad astronómica local y, simultáneamente el comienzo de un cambio radical en la estructura del sistema educativo argentino. ?`Contempla ese cambio el objetivo que postulara Sérsic? ?`Estamos en condiciones de afirmar que estamos en camino de lograrlo? ?`Con qué parámetros?. Presentamos aquí un panorama general sobre algunas de las acciones realizadas en función de alcanzar esa alfabetización científica, analizando exclusivamente la actividad de enseñanza hasta el nivel universitario, sin detenernos en el mismo, ya que lo consideramos una instancia superior e independiente de aquella alfabetización. Tampoco nos referiremos a la tarea de difusión, divulgación o popularización de la Astronomía, ya que su condición de asistemática y subjetiva no es evaluable en términos de la formación integral de un individuo.

    SUMMARY OBJECTIVE To investigate smoking patterns in an elderly, low-income population and to identify predictors of smoking cessation, in addition to analyzing the importance of smoking in relation to other risk factors for hospitalization. DESIGN The data were part of an urban health study conducted among 740 individuals aged ≥60 years in three suburban communities of low socio-economic status in Beirut, one of them a refugee camp. A detailed interview schedule was administered that included comprehensive social and health information. RESULTS The overall prevalence of current smokers was 28.1%. Almost half of the group were ever smokers, of whom 44% had quit smoking when they experienced negative health effects. Having at least one chronic illness and having a functional disability significantly increased the odds of smoking cessation. In addition, being a former smoker increased the likelihood of hospital admission. CONCLUSIONS This study is of particular importance, as it has implications for similar low-income and refugee communities in the region and elsewhere. There is a need for more concerted efforts by public health officials to target elderly individuals as a group for smoking cessation interventions, particularly now that mortality and health benefits have been well documented. RÉSUMÉ OBJECTIF Investiguer les types de tabagisme dans une population âgée à faibles revenus et identifier les facteurs prédictifs de l’arrêt du tabagisme, tout en analysant l’importance du tabagisme par rapport aux autres facteurs de risque d’hospitalisation. SCHÉMA Les données constituent une fraction de l’étude de santé urbaine menée chez 740 personnes âgées de ≥60 ans à Beyrouth dans trois collectivités suburbaines à faible statut socio-économique dont une des trois se situe dans un camp de réfugiés. Un schéma détaillé d’interview a été utilisé comportant des informations complètes sur le plan social et celui de la santé. RÉSULTATS La prévalence globale des fumeurs actuels est de 28,1%. Près de la moitié des personnes âgées ont fumé à un moment quelconque dans leur vie et parmi celles-ci, 44% ont cessé de fumer. Les personnes âgées ont cessé de fumer lorsqu’elles en ont perçu les effets négatifs sur la santé. Le fait d’avoir au moins une maladie chronique et de souffrir d’une incapacité fonctionnelle ont augmenté d’une façon significative les chances d’arrêt du tabagisme. De plus, le fait d’être un ancien fumeur a augmenté le risque d’admission hospitalière. CONCLUSIONS Cette étude est d’une importance particulière car ses implications s’élargissent à des collectivités à faibles revenus similaires et chez les réfugiés dans la région ainsi qu’ailleurs. Il est nécessaire que les responsables de la santé publique fassent un effort plus concerté pour cibler les personnes âgées comme groupe en vue d’interventions d’arrêt du tabagisme, d’autant plus que les avantages en matière de mortalité et de santé ont aujourd’hui été bien documentés. RESUMEN OBJETIVOS Investigar los tipos de hábito tabáquico en una población de personas ancianas, de bajos ingresos y determinar los factores pronósticos del abandono del hábito. Asimismo, se analizó la importancia del tabaquismo en relación con otros factores de riesgo de hospitalización. DISEÑO Los datos formaban parte de un estudio de salud urbana de 740 personas de ≥60 años de edad, en tres comunidades suburbanas de bajo estrato socioeconómico en Beirut, una de las cuales era un campo de refugiados. Se administró una entrevista estructurada que aportaba amplia información social y sanitaria. RESULTADOS La prevalencia global de fumadores fue de 28,1%. Casi la mitad de las personas ancianas había sido fumadora en algún momento y 44% habían abandonado el tabaquismo. Estas personas abandonaron el hábito tabáquico cuando tuvieron repercusiones negativas sobre su salud. La presencia de por lo menos una enfermedad crónica y de discapacidad funcional aumentó en forma significativa las probabilidades de abandono del tabaquismo. Además, el antecedente de tabaquismo aumentó el riesgo de hospitalización. CONCLUSIÓN El presente estudio reviste una importancia particular, pues sus implicaciones son amplias para comunidades similares de escasos ingresos y de refugiados en esta y otras regiones. Pone en evidencia la necesidad de iniciativas más coordinadas por parte de los funcionarios de salud pública, destinadas a enfocar las campañas de abandono del tabaquismo en la población de edad mayor ; aún más hoy, cuando se ha demostrado la utilidad del abandono en términos de disminución de la mortalidad y consecuencias positivas para la salud.

    Resumen El objetivo de este estudio fue desarrollar fotonovelas, un tipo de novela gráfica popular en la población latina, para crear conciencia y educar sobre los trastornos de la conducta alimentaria (TCA). Cuatro caricaturas ilustradas y guiones adaptados para adultos y adolescentes de ambos sexos fueron presentados en discusiones focales y en una entrevista de profundidad. Diecisiete latinos adultos (14 mujeres; 3 hombres) y 10 adolescentes (9 féminas; 1 varón) participaron en el estudio. Los participantes encontraron las fotonovelas interesantes y que captaban más la atención que los folletos tradicionales. El uso del espanglish y la clarificación de las diferencias entre los TCA fueron sugeridos por las adolescentes femeninas. Los adultos varones sugirieron cambiar el título, que se enfocara en las consecuencias en la salud de los TCA para que llame la atención en los hombres a leer la historia. Basado en la aceptación encontrada en este estudio, la fotonovela pudiera ser una avenida prometedora para crear conciencia y educar a la comunidad latina sobre los TCA en los Estados Unidos.

    Casagrande, A. R.

    En principio, este proyecto intenta lograr el mayor aprovechamiento posible del instrumental que se dispone, buscando la manera de optimizar y hacer más eficiente el servicio que brinda el CASLEO a la comunidad astronómica. El mismo consiste en utilizar dispositivos ya existentes en el telescopio, y darle una utilidad. Tal es el caso del camino óptico destinado al foco Coude. Si tenemos en cuenta que disponemos de un tercer espejo Coude, con todos sus mecanismos automatizados, (actualmente sin uso), una distancia apropiada del plano focal, el espacio y el lugar físico necesario para instalar un periférico, es posible la habilitación de un foco Nasmyth en el telescopio 2,15mts. El hecho de contar con este nuevo foco, redundará en importantes beneficios. En primer lugar, posibilitará la observación, casi simultánea, con dos instrumentos. Otro aspecto a tener en cuenta, es que disminuirá el frecuente cambio del instrumental periférico, motivo este que degrada su ideal puesta a punto. Por último, también de interés, es de destacar su escaso costo de ejecución.

    this study developed a people-centered care (PCC) partnership model for the aging society to address the challenges of social changes affecting people's health and the new role of advanced practice nurses to sustain universal health coverage. a people-centered care partnership model was developed on the basis of qualitative meta-synthesis of the literature and assessment of 14 related projects. The ongoing projects resulted in individual and social transformation by improving community health literacy and behaviors using people-centered care and enhancing partnership between healthcare providers and community members through advanced practice nurses. people-centered care starts when community members and healthcare providers foreground health and social issues among community members and families. This model tackles these issues, creating new values concerning health and forming a social system that improves quality of life and social support to sustain universal health care through the process of building partnership with communities. a PCC partnership model addresses the challenges of social changes affecting general health and the new role of advanced practice nurses in sustaining UHC. o estudo desenvolveu um modelo de parceria de cuidados centrados nas pessoas (CCP) para uma sociedade que está envelhecendo, com o fim de enfrentar os desafios das mudanças sociais que afetam a saúde das pessoas e o novo papel da prática avançada de enfermagem para sustentar a cobertura universal de saúde. um modelo de parceria de cuidados centrados nas pessoas foi desenvolvido com base na meta-síntese qualitativa da literatura e a avaliação de 14 projetos relacionados.

  6. Analysis of phospholipid fatty acids (PLFA) to characterize microbial communities in aquifers

    NASA Astrophysics Data System (ADS)

    Green, Christopher T.; Scow, Kate M.

    This paper reviews published applications of lipid-based biochemical techniques for characterizing microbial communities in aquifers and other deep subsurface habitats. These techniques, such as phospholipid fatty acid (PLFA) analysis, can provide information on a variety of microbial characteristics, such as biomass, physiology, taxonomic and functional identity, and overall community composition. In addition, multivariate statistical analysis of lipid data can relate spatial or temporal changes in microbial communities to environmental factors. The use of lipid-based techniques in the study of groundwater microbiology is advantageous because they do not require culturing and can provide quantitative data on entire communities. However, combined effects of physiological and phylogenetic changes on the lipid composition of a community can confound interpretation of the data, and many questions remain about the validity of various lipid techniques. Despite these caveats, lipid-based research has begun to show trends in community composition in contaminated and pristine aquifers that contribute to our understanding of groundwater microbial ecology and have potential for use in optimization of bioremediation of groundwater pollutants. Résumé Ce papier passe en revue les applications des techniques biochimiques basées sur les lipides pour caractériser les communautés microbiennes présentes dans les aquifères et dans les autres habitats souterrains profonds. Ces techniques, telles que l'analyse des acides gras phospholipidiques (PLFA), peuvent fournir des informations sur un ensemble de caractères microbiens, tels que la biomasse, la physiologie, l'identité taxonomique et fonctionnelle, et surtout la composition de la communauté. En outre, l'analyse statistique multivariée des données sur les lipides peut établir les liens entre des changements spatiaux ou temporels dans la communauté microbienne et des facteurs environnementaux. L'utilisation des techniques basées sur les lipides dans l'étude de la microbiologie des eaux souterraines est intéressante parce qu'elle ne nécessite pas de mise en culture et qu'elle peut fournir des données quantitatives sur les communautés dans leur ensemble. Toutefois, les effets combinés de changements physiologiques et phylogénétiques sur la composition d'une communauté peuvent brouiller l'interprétation des données de nombreuses questions se posent sur la validité des différentes techniques lipidiques. Malgré ces oppositions, la recherche basée sur les lipides a commencéà montrer des tendances dans la composition des communautés dans les aquifères pollués et dans ceux non perturbés ces résultats contribuent ainsi à notre compréhension de l'écologie microbienne des eaux souterraines et montrent qu'il existe un potentiel pour leur utilisation en vue d'une optimisation de la dépollution biologique des eaux souterraines. Resumen Se revisan distintas técnicas bioquímicas que se basan en el análisis de lípidos para caracterizar las comunidades microbianas en hábitats subsuperficiales, incluyendo acuíferos. Estas técnicas, entre las que se incluye el análisis de ácidos grasos fosfolípidos (PLFA), pueden proporcionar información sobre toda una serie de características de las comunidades microbianas, como su biomasa, fisiología, identidad taxonómica y funcional y composición. Además, el análisis estadístico multivariado de los datos de lípidos permite relacionar los cambios espaciales o temporales en las comunidades microbianas con factores ambientales. Las técnicas basadas en lípidos son muy útiles para el estudio microbiológico de las aguas subterráneas, puesto que no requieren cultivos y además proporcionan datos cuantitativos de comunidades completas. Sin embargo, la acción combinada de los cambios fisiológicos y filogenéticos en la composición de lípidos en una comunidad pueden confundir la interpretación de los datos, por lo existen muchas cuestiones abiertas respecto a la validez de algunas de estas técnicas. A pesar de estas dificultades, estas técnicas han permitido detectar diferentes tendencias en la composición de las comunidades en acuíferos con y sin contaminación, lo que contribuye a nuestro entendimiento de la ecología microbiana de los acuíferos. Este último aspecto tiene un uso potencial en la optimización de los métodos de biorremediación de acuíferos.

  9. Un asteroide proveniente de la Luna

    NASA Astrophysics Data System (ADS)

    Tancredi, G.

    El descubrimiento de un débil objeto en movimiento por el telescopio Spacewatch (un instrumento dedicado a la búsqueda de Asteroides Cercanos a la Tierra) en 1991, ha generado una gran controversia en la comunidad planetaria. El objeto, denominado 1991 VG, tiene elementos orbitales llamativamente similares a los de la Tierra, lo que ha llevado a B. G. Marsden a aventurar:``El objeto podría ser una nave espacial en retorno (IAUC 5387)". Luego de analizar las características dinámicas de 1991 VG y las diferentes hipótesis sobre su origen, favorecemos la alternativa de que el objeto es un gran fragmento de material eyectado de la Luna durante un reciente impacto (en las últimas decenas de miles de años). El hallazgo en 1983 en la Antártida de meteoritos con composición tipo lunar, confirma la posibilidad de que material de la superficie del satélite puede ser eyectado a velocidades superiores a la de escape del sistema Tierra-Luna y alcance órbitas heliocéntricas. Los elementos orbitales de 1991 VG corresponden a los valores alcanzados por partículas que apenas escapan de la gravedad lunar y entran en órbitas heliocéntricas a través del punto Lagrangiano exterior del sistema Tierra-Sol.

    Resumen En el mundo hay más personas en la etapa de la juventud que en cualquier otra etapa del desarrollo. La juventud en Puerto Rico enfrenta muchas situaciones que inciden en su desarrollo y preparación para la adultez. Por lo tanto, es imperante identificar intervenciones para el desarrollo positivo de la juventud que han demostrado ser basadas en la evidencia. Además, a partir de dicha identificación, desarrollar prácticas que ayuden a los jóvenes a desarrollarse para prevenir situaciones adversas, promover experiencias positivas y propiciar que los niños y jóvenes estén involucrados y comprometidos. Se identificaron 147 intervenciones a través de una revisión tradicional de la literatura científica estadounidense. Los resultados reflejan que las intervenciones atienden la reducción de factores de riesgo y el incremento de factores de protección. Sin embargo, ninguna intervención propicia que los niños y jóvenes estén involucrados y comprometidos con su desarrollo óptimo y con sus comunidades. No obstante, todas brindan herramientas que podrían ser de utilidad para fomentar dichas prácticas en el contexto de Puerto Rico. De las 147 intervenciones identificadas seis están diseñadas para la población puertorriqueña residente en la Isla. Con el propósito de hacer la información accesible a los profesionales y la comunidad se expandió la colección del Archivo de Programas y Prácticas Basadas en Evidencia para la Prevención.

    The Urbana coherent-scatter radar was used to observe the upper troposphere and lower stratosphere, and 134 hours of data were collected. Horizontal wind measurements show good agreement with balloon-measured winds. Gravity waves were frequently observed, and were enhanced during convective activity. Updrafts and downdrafts were observed within thunderstorms. Power returns are related to hydrostatic stability, and changes in echo specularity are shown.

    to analyze the influence of sexual violence on the perception and management of the risk of HIV in women married to migrants. study with an ethnographic approach carried out in urban and rural communities. Data were obtained by methodological triangulation, with participant and non-participant observation, as well as interviews. The informants were 21 women married to international migrants. The interviews were transcribed and discourse analysis was applied to them. three categories emerged from the speeches to problematize the influence of sexual violence in the perception and management of the risk of HIV: "Characterization of sexual practices in the context of migration", "Experiences of sexual violence" and "Construction of the risk of HIV-AIDS". women have difficulty to recognize the acts of sexual violence in their daily lives, and their perceptions of risk are not decisive in the management of the threat to which they are exposed. Therefore, it is becoming increasingly urgent that nursing problematizes the sexual violence within "steady couples", as a challenge to the promotion of healthy lifestyles. analisar a influência que a violência sexual tem na percepção e gestão do risco de HIV em mulheres casadas com migrantes. estudo com enfoque etnográfico, em comunidades urbanas e rurais.

    Parker, J. W.; Bowhill, S. A.

    1986-01-01

    The coherent-scatter technique, as used with the Urbana radar, is able to measure relative changes in electron density at one altitude during the progress of a solar flare when that altitude contains a statistically steady turbulent layer. This work describes the analysis of Urbana coherent-scatter data from the times of 13 solar flares in the period from 1978 to 1983. Previous methods of measuring electron density changes in the D-region are summarized. Models of X-ray spectra, photoionization rates, and ion-recombination reaction schemes are reviewed. The coherent-scatter technique is briefly described, and a model is developed which relates changes in scattered power to changes in electron density. An analysis technique is developed using X-ray flux data from geostationary satellites and coherent scatter data from the Urbana radar which empirically distinguishes between proposed D-region ion-chemical schemes, and estimates the nonflare ion-pair production rate.

    to evaluate the relationship between absences in scheduled appointments and the number of non-communicable chronic diseases and to investigate the relationship between spatial distribution of these diseases and social vulnerability, using geoprocessing. a quantitative study of sequential mixed approach by analyzing 158 medical records of male users to relate the absences and 1250 medical records for geoprocessing. the higher the number of absences in the scheduled medical appointments, the less were the number of non-communicable chronic diseases and the ones listed in the International Classification of Diseases in single men. There were 21 significant geostatistically cases of glucose intolerance in the urban area. Of these, 62% lived in a region with a social vulnerability rating of Very Low, Medium 19%, 14% Low and 5% High. it was observed that the older the men, the greater is the number of chronic diseases and the less they miss scheduled appointments. Regarding the use of geoprocessing, we obtained a significant number of cases of glucose intolerance in urban areas, the majority classified as Very Low social vulnerability. It was possible to relate the spatial distribution of these diseases with the social vulnerability classification; however, it was not possible to perceive a relationship of them with the higher rates of social vulnerability. avaliar a relação entre as faltas em consultas agendadas e o número de doenças crônicas não transmissíveis e averiguar a relação entre distribuição espacial dessas doenças e vulnerabilidade social, utilizando-se o geoprocessamento. estudo quantitativo, de abordagem mista sequencial, sendo analisados 158 prontuários de usuários do sexo masculino para se relacionar as faltas e 1250 prontuários para o geoprocessamento. quanto maior o número de faltas nas consultas médicas agendadas, menores foram a quantidade de doenças crônicas não transmissíveis e as listadas na Classificação Internacional de Doenças em homens solteiros.

    Abstract We present the first community-level study of the associations of both roads and other human disturbances with the distribution of mammals in Gabon (central Africa). Our study site was in an oil concession within a littoral mosaic landscape. We conducted surveys along 199 line transects and installed camera traps on 99 of these transects to document mammal presence and abundance. We used generalized linear mixed-effect models to document associations between variables related to the ecosystem (land cover, topography, and hydrology), roads (coating, width of rights of way, condition, type of vehicle used on the road, traffic level, affiliation of users, and general type of road), and other human disturbances (urbanization, agriculture, hunting, logging, gathering, and industrial activities) and the abundance or presence of 17 species or groups of mammals including elephant (Loxodonta cyclotis), buffalo (Syncerus caffer), sitatunga (Tragelaphus spekei), red river hog (Potamochoerus porcus), smaller ungulates, gorilla (Gorilla gorilla), chimpanzee (Pan troglodytes), side-striped jackal (Canis adustus), carnivores, monkeys, and large rodents. Some types of roads and other human disturbances were negatively associated with the abundance or presence of elephants, buffalos, gorillas, sitatungas, some monkeys, and duikers. The pattern of associations of mammals with roads and other human disturbances was diverse and included positive associations with road presence (red river hog, some monkeys, and duikers), agriculture (sitatunga, small carnivores, and large rodents) and industrial activities (sitatunga, red river hog, red duikers, and side-striped jackal). Our results suggest that the community of mammals we studied was mostly affected by hunting, agriculture, and urbanization, which are facilitated by road presence. We recommend increased regulation of agriculture, hunting, and road building in the area. Distribución de una Comunidad de Mamíferos en Relación a Carreteras y Otras Perturbaciones Humanas en Gabón, Africa Central Resumen Presentamos el primer estudio a nivel de comunidad de la relación entre carreteras y otras perturbaciones humanas con la distribución de mamíferos en Gabón (África central). Nuestro sitio de estudio está dentro de una concesión petrolera en un paisaje litoral heterogéneo. Realizamos muestreos a lo largo de 199 transectos lineales e instalamos cámaras trampa en 99 de ellos para documentar la presencia y abundancia de mamíferos. Utilizamos modelos lineales generalizados con efectos mixtos para documentar las asociaciones entre variables relacionadas con el ecosistema (cobertura de suelo, topografía e hidrología), carreteras (tipo de revestimiento, ancho de derecho de vía, condición, tipo de vehículos que utilizan la carretera, nivel de tráfico, afiliación de los usuarios y el tipo general de carretera) y otras perturbaciones humanas (urbanización, agricultura, caza, tala, recolecta y actividades industriales) y la abundancia o presencia de 17 especies o grupos de mamíferos incluyendo elefantes (Loxodonta cyclotis), búfalo (Syncerus caffer), sitatunga (Tragelaphus spekei), cerdo rojo de río (Potomochoerus porcus), ungulados pequeños, gorila (Gorilla gorilla), chimpancé (Pan troglodytes), chacal con rayas a los lados (Canis adustus), carnívoros, monos y roedores de talla grande. Ciertos tipos de carreteras y otras perturbaciones humanas estuvieron asociadas negativamente con la abundancia o presencia de elefantes, búfalos, gorilas, sitatungas, algunos monos y antílopes. Los patrones de asociación de mamíferos con carreteras y otras perturbaciones humanas fueron diversos e incluyen asociaciones positivas con la presencia de carreteras (cerdo rojo de río, algunos monos y antílopes), agricultura (sitatunga, carnívoros pequeños y roedores de talla grande) y actividades industriales (sitatunga, cerdo rojo de río, antílope rojo y chacal con rayas a los lados). Nuestros resultados sugieren que la comunidad de mamíferos que estudiamos fue afectada principalmente por la caza, agricultura y urbanización, que son facilitadas por la presencia de carreteras. Recomendamos una mayor regulación de la agricultura, caza y construcción de carreteras en el área. PMID:23410077

    Although astronomy is considered one of the older sciences of humanity and that the understanding of its concepts has brought tremendous advances to Science and therefore, to society, it is observed that a significant portion of people live outside of this kind of knowledge. According to the Parâmetros Curriculares Nacionais for basic education, it is the school responsibility the dissemination of scientifically correct concepts, including those related to astronomy. Concerning this issue, we present a survey of 140 students of ninth grade of elementary school and 120 third-grade high-school students from four schools in the region of Passo Fundo/RS. We sought to determine, through a questionnaire consisting of open and multiple choice questions, the knowledge of this group of students about the basic terms and astronomical phenomena, and also verify that the hit rate increases as they advance through the different and progressive grades of primary and secondary education. Overall, the results show that the teaching of astronomy in basic education is facing problems. Of the 20 issues investigated, in 17 the indicators are similar in the correct answers given by students for elementary and middle school, revealing that many misconceptions still remain along basic education. This demonstrates that such issues are not - or are rarely - covered during these two school levels. Thus, we conclude that the discussion of concepts related to astronomy should receive greater emphasis on approaching different subjects, requiring a national action in support of their teaching. It is believed that a national action should be supported by a triple pillar of collective actors: the scientific community, semi-professional astronomy community and the school community. Finally, this pillar would be the basis for future discussions related to the performance of these protagonists as a means to promote active changes in the curricular structure, providing, in more effective ways, the learning of astronomy in basic education. Embora a astronomia seja considerada uma das ciências mais antigas da humanidade e ainda que a compreensão de seus conceitos tenha trazido enormes avanços para a Ciência e, consequentemente, para a sociedade, observa-se que uma parcela significativa de pessoas encontra-se à margem desses conhecimentos. De acordo com os Parâmetros Curriculares Nacionais para a Educação Básica, cabe à escola a difusão dos conceitos cientificamente corretos, entre eles os relacionados à área de astronomia. Pertinente a essa questão, apresenta-se uma pesquisa realizada com 140 estudantes do nono ano do ensino fundamental e com 120 estudantes da terceira série do ensino médio de quatro escolas da região de Passo Fundo/RS. Buscou-se averiguar, por meio de um questionário composto de questões abertas e de múltipla escolha, o conhecimento desse grupo de estudantes acerca de termos e fenômenos astronômicos básicos e, também, verificar se o índice de acertos cresce à medida que eles avançam nas diferentes e gradativas séries dos ensinos fundamental e médio. De modo geral, os resultados apresentados demonstram que o ensino de astronomia na educação básica enfrenta deficiências. Das 20 questões investigadas, em 17 os índices de acertos são semelhantes nas respostas dadas por estudantes de nível fundamental e médio, revelando que muitas concepções equivocadas permanecem ao longo da educação básica. Isso evidencia que tais temas não são - ou são pouco - abordados durante esses dois níveis de escolarização. Assim, conclui-se que a discussão dos conceitos relacionados com a astronomia deve receber maior ênfase na abordagem dos diferentes conteúdos, sendo necessária uma ação nacional em prol do seu ensino. Acredita-se que essa ação nacional deve estar apoiada em um pilar triplo de atores coletivos: comunidade científica, comunidade astronômica semiprofissional e comunidade escolar. Por fim, esse pilar seria a base para futuras discussões relacionadas à atuação dessas instâncias como meio de promover mudanças ativistas na estrutura curricular, proporcionando, mais efetivamente, a educação em astronomia no ensino básico. Si bien la astronomía es considerada una de las ciencias más antiguas de la humanidad y aunque la comprensión de sus conceptos haya traído enormes avances para la ciencia y, consecuentemente, para la sociedad, se observa que una parte significativa de personas se encuentran al margen de estos conocimientos. De acuerdo con los Parámetros Curriculares Nacionales para la Educación Básica, corresponde a la escuela la difusión de los conceptos científicamente correctos, entre ellos los relacionados al área de astronomía. Sobre esta cuestión, se presenta una investigación realizada con 140 estudiantes del noveno año de la enseñanza fundamental y con 120 estudiantes del tercer año de la enseñanza de nivel medio de cuatro escuelas de la región de Passo Fundo/RS. Se pretendía averiguar, por medio de un cuestionario compuesto de preguntas abiertas y de opción múltiple, el conocimiento de este grupo de alumnos sobre términos y fenómenos astronómicos básicos y, también, si el índice de aciertos crece en la medida que los alumnos avanzan a los diferentes y sucesivos años de la enseñanza fundamental y media. De modo general, los resultados demuestran que la enseñanza de astronomía en la educación básica muestra deficiencias. De los 20 asuntos investigados, 17 revelan índices de aciertos semejantes en las respuestas dadas por los estudiantes de nivel básico y medio, mostrando que muchas concepciones equivocadas permanecen a lo largo de la educación básica. Esto hace evidente que estos temas no son - o son poco - abordados durante esos niveles de escolarización. Así, puede concluirse que la discusión de los conceptos relacionados a la astronomía debe recibir un mayor énfasis en cuanto al abordaje de los diferentes contenidos, siendo necesaria una acción nacional en pro de su enseñanza. Es necesario destacar que esa acción nacional debe estar apoyada en un pilar triple de actores colectivos: comunidad científica, comunidad de astronomía semi profesional y la comunidad escolar. En fin, ese pilar sería la base para futuras discusiones relacionadas a la actuación de esas instancias como vía para promover cambios en la estructura curricular, proporcionando más efectivamente, la educación en astronomía en la enseñanza de nivel básico.

    Latino children experience disparities in health care access and quality. Family advisory groups for clinics and hospitals may be one way to address disparities. We implemented and sustained an advisory board whose parent participants were exclusively limited-English proficient Latina mothers. As part of the board evaluation, we conducted semistructured individual interviews with parent participants during initial participation and after the final board meeting of the year. Members were satisfied with their board participation in both initial and follow-up interviews. They reported that board membership was an important way to improve clinic services and a unique opportunity for Latinos in the community. Experiences of discrimination and marginalization in health care settings were a theme across interviews. Members reported board membership countered these negative experiences. An advisory board including Spanish-speaking parents is an opportunity to engage vulnerable populations, which may result in broader impact on health care disparities. Los niños latinos experimentan disparidad en el acceso y calidad del cuidado de salud. Grupos de familias asesoras para clínicas y hospitales pueden ser una forma de hacer frente a las disparidades. Nosotros implementamos y sostuvimos un consejo asesor cuyos participantes fueron exclusivamente madres latinas con dominio limitado del inglés. Como parte de la evaluación del consejo, condujimos entrevistas semi-estructuradas individuales con las madres participantes durante la participación inicial y después de la última reunión del año del consejo. Los miembros estaban satisfechas con su participación en el consejo en ambas entrevistas, la inicial y la de seguimiento. Ellas reportaron que ser miembros del consejo era una forma importante para mejorar los servicios de la clínica y una oportunidad única para los latinos en la comunidad. Las experiencias de discriminación y marginalización en las instalaciones de cuidado de salud eran un tema a lo largo de las entrevistas. Los miembros reportaron que ser miembros del consejo contrarrestó estas experiencias negativas. Un consejo asesor incluyendo padres que hablan español es una oportunidad para involucrar a poblaciones vulnerables, las cuales pueden resultar en un impacto más amplio en las disparidades del cuidado de salud.

    Although many taxa have declined globally, conservation actions are inherently local. Ecosystems degrade even in protected areas, and maintaining natural systems in a desired condition may require active management. Implementing management decisions under uncertainty requires a logical and transparent process to identify objectives, develop management actions, formulate system models to link actions with objectives, monitor to reduce uncertainty and identify system state (i.e., resource condition), and determine an optimal management strategy. We applied one such structured decision-making approach that incorporates these critical elements to inform management of amphibian populations in a protected area managed by the U.S. National Park Service. Climate change is expected to affect amphibian occupancy of wetlands and to increase uncertainty in management decision making. We used the tools of structured decision making to identify short-term management solutions that incorporate our current understanding of the effect of climate change on amphibians, emphasizing how management can be undertaken even with incomplete information.

    There are few Spanish language interactive, technology-driven health education programs. Objectives of this feasibility study were to: 1) learn more about computer and technology usage among Hispanic women living in a rural community; and 2) evaluate acceptability of the concept of using an embodied conversational agent (ECA) computer application among this population. A survey about computer usage history and interest in computers was administered to a convenience sample of 26 women. A sample video prototype of a hospital discharge ECA was administered followed by questions to gauge opinion about the ECA. Data indicate women exhibited both a high level of computer experience and enthusiasm for the ECA. Feedback from community is essential to ensure equity in state of the art dissemination of health information. Hay algunos programas interactivos en español que usan la tecnología para educar sobre la salud. Los objetivos de este estudio fueron: 1) aprender más sobre el uso de computadoras y tecnología entre mujeres Hispanas que viven en comunidades rurales y 2) evaluar la aceptabilidad del concepto de usar un programa de computadora utilizando un agente de conversación encarnado (ECA) en esta población. Se administro una encuesta sobre el historial de uso y del interés de aprender sobre computadoras fue a 26 mujeres por muestreo de conveniencia. Un ejemplo del prototipo ECA en forma de video de un alta hospitalaria fue administrado y fue seguido por preguntas sobre la opinión que tenían del ECA. Los datos indican que las mujeres mostraron un alto nivel de experiencia con las computadoras y un alto nivel de entusiasmo sobre el ECA. La retroalimentación de la comunidad es esencial para asegurar equidad en la diseminación de información sobre la salud con tecnología de punta. PMID:26671558

    In this study the production of secondary metabolites by a virulent strain of Sardiniella urbana, a recently described pathogen originally found on declining European hackberry trees in Italy, was investigated for the first time. Chemical analysis of the culture filtrate extracts led to the isolation of three well known compounds as R-(-)-mellein and (3R,4R)-and (3R,4S)-4-hydroxy melleins which were identified by spectroscopic methods (essentially NMR and ESIMS). The isolated compounds were tested for their phytotoxic, antifungal and zootoxic activities. Among them, only R-(-)-mellein was found to be active.

A análise pretende contribuir para que políticas públicas dedicadas à promoção da saúde sexual da juventude considerem a religiosidade, no contexto de um estado laico e da promoção do direito à prevenção. Foram realizadas 26 entrevistas abertas e semidirigidas em diferentes comunidades da região metropolitana da cidade de São Paulo (comunidades católicas, da umbanda, do candomblé e de diferentes denominações evangélicas) sobre iniciação sexual, casamento, gravidez, contracepção e prevenção das DST/Aids, homossexualidade, aborto e direitos humanos. Observou-se como jovens e autoridades religiosas convivem com a tensão entre tradição e modernidade e os distintos discursos sobre a sexualidade. Como sujeitos religiosos (do discurso religioso) e sujeitos sexuais (de discursos sobre sexualidade), devem ser incorporados pelos programas como sujeitos de direito nos termos de sua religiosidade.

    Objectives To examine the prevalence of seizures, epilepsy and seropositivity to cysticercosis in rural villagers (cysticercosis-endemic setting), rural-to-urban migrants into a non-endemic urban shanty town and urban inhabitants of the same non-endemic shanty town. Methods Three Peruvian populations (n = 985) originally recruited into a study about chronic diseases and migration were studied. These groups included rural inhabitants from an endemic region (n = 200), long-term rural-to-urban migrants (n = 589) and individuals living in the same urban setting (n = 196). Seizure disorders were detected by a survey, and a neurologist examined positive respondents. Serum samples from 981/985 individuals were processed for cysticercosis antibodies on immunoblot. Results Epilepsy prevalence (per 1000 people) was 15.3 in the urban group, 35.6 in migrants and 25 in rural inhabitants. A gradient in cysticercosis antibody seroprevalence was observed: urban 2%, migrant 13.5% and rural group 18% (P < 0.05). A similarly increasing pattern of higher seroprevalence was observed among migrants by age at migration. In rural villagers, there was strong evidence of an association between positive serology and having seizures (P = 0.011) but such an association was not observed in long-term migrants or in urban residents. In the entire study population, compared with seronegative participants, those with strong antibody reactions (≥ 4 antibody bands) were more likely to have epilepsy (P < 0.001). Conclusions It is not only international migration that affects cysticercosis endemicity; internal migration can also affect patterns of endemicity within an endemic country. The neurological consequences of cysticercosis infection likely outlast the antibody response for years after rural-to-urban migration. Objectifs Examiner la prévalence des crises d’épilepsie, de l’épilepsie et de la séropositivité à la cysticercose chez les villageois des zones rurales (cadre endémique pour la cysticercose), chez les migrants des zones ruraux vers les zones urbaines dans un bidonville urbain non endémique et chez les habitants urbains du même bidonville non endémique. Méthodes Trois populations péruviennes (n = 985) recrutées initialement dans une étude sur les maladies chroniques et la migration, ont été étudiées. Ces groupes comprenaient des habitants de zones rurales d'une région d'endémie (n = 200), des migrants de long terme de zones ruraux vers les villes (n = 589) et les personnes vivant dans le même milieu urbain (n = 196). Les troubles épileptiques ont été détectés par un sondage et un neurologue a examiné les répondants positifs. Des échantillons de sérum de 981/985 individus ont été testés pour les anticorps de cysticercose par Immunoblot. Résultats La prévalence de l’épilepsie (pour 1000 personnes) était de 15,3 dans le groupe urbain; 35,6 chez les migrants et 25 dans la population rurale. Un gradient dans la séroprévalence des anticorps de la cysticercose a été observé: dans le groupe urbain 2%, le groupe de migrants 13,5% et le groupe rural 18% (p <0,05). Une tendance croissante similaire de séroprévalence plus élevée a été observée chez les migrants selon l’âge à la migration. Chez les villageois ruraux, il y avait des preuves solides d'une association entre une sérologie positive et le fait d'avoir des crises (p = 0,011), mais une telle association n'a pas été observée chez les migrants de long terme ou chez les résidents urbains. Dans l'ensemble de la population de l’étude, ceux avec de fortes réactions d'anticorps (≥ 4 bandes d'anticorps) étaient plus susceptibles d'avoir l’épilepsie (p <0,001) comparé aux participants séronégatifs. Conclusions La migration internationale n'est pas la seule qui affecte l'endémicité de la cysticercose; la migration interne peut aussi modifier les profils d'endémicité au sein d'un même pays d'endémie. Les conséquences neurologiques de l'infection par la cysticercose sont susceptibles de survivre à la réponse d'anticorps durant des années après la migration des zones rurales vers les zones urbaines. Objetivos Examinar la prevalencia de convulsiones, epilepsia, y seropositividad para cisticercosis entre población rural (de zonas endémicas para cisticercosis), inmigrantes provenientes de zonas rurales a tugurios urbanos no endémicos, y habitantes urbanos de los mismo tugurios urbanos no endémicos. Métodos Se estudiaron tres poblaciones peruanas (n=985) originalmente reclutadas en un estudio de enfermedades crónicas y migración. Estos grupos incluían habitantes rurales de una región endémica (n=200), inmigrantes de larga duración de zonas rurales a urbanas (n=589), e individuos que vivían en la misma zona urbana (n=196). Las convulsiones se detectaron mediante una encuesta y un neurólogo examinó a quienes habían respondido positivamente. Se procesaron muestras de suero de 981/985 individuos en busca de anticuerpos para cisticercosis mediante inmunoblot. Resultados La prevalencia de epilepsia (por 1,000 personas) era de 15.3 en el grupo urbano, 35.6 en inmigrantes y 25 en habitantes rurales. Se observó un gradiente en la seroprevalencia de los anticuerpos para cisticercosis: grupos urbano 2%, inmigrante 13.5% y rural 18% (p<0.05). Se observó un patrón de aumento similar de mayor seroprevalencia entre inmigrantes según la edad que tenían en el momento de emigrar. En pobladores rurales, había una evidencia importante de asociación entre tener una serología positiva y sufrir convulsiones (p=0.011), pero esta asociación no se observaba en inmigrantes de larga duración o residentes urbanos. En la población al completo, comparada con los participantes seronegativos, aquellos con una fuerte reactividad de anticuerpos (≥4 bandas de anticuerpos) tenían una mayor probabilidad de sufrir epilepsia (p<0.001). Conclusiones No solo la migración internacional afecta la endemicidad de cisticercosis; la migración interna también puede afectar los patrones de endemicidad dentro de un país endémico. Las consecuencias neurológicas de la infección por cisticercos podrían durar más que la respuesta a anticuerpos años después de la migración de zonas rurales a zonas urbanas. PMID:25581851

    The design, development, and first observations of a high power meteor-radar system located near Urbana, Illinois are described. The roughly five-fold increase in usable echo rate compared to other facilities, along with automated digital data processing and interferometry measurement of echo arrival angles, permits unsurpassed observations of tidal structure and shorter period waves. Such observations are discussed. The technique of using echo decay rates to infer density and scale height and the method of inferring wind shear from radial acceleration are examined. An original experiment to test a theory of the Delta-region winter anomaly is presented.

    To be effective, HIV/AIDS interventions must be culturally and linguistically appropriate and must occur within the context of the specific community in which they are delivered. In this article, the development of a culture-specific lay health advisor (LHA) program, Protegiendo Nuestra Comunidad, for recently immigrated Mexicans is described. This program is one component of a collaborative inquiry research project involving community participants and researchers working as partners in carrying out and assessing a program for the prevention of HIV/AIDS. The collaborative inquiry process was applied as an empowerment philosophy and methodology of Paulo Freire and an ecological framework was used for the development of Protegiendo Nuestra Comunidad. The use of principles of empowerment for curriculum development, teaching methodology, and program delivery are described.

  4. Development of a seroprevalence map for avian influenza in broiler chickens from Comunidad Valenciana, Spain.

    PubMed

    2014-12-01

    The aim of this study was to design and implement a seroprevalence map based on business intelligence for low pathogenicity notifiable avian influenza (LPNAI) in broilerchickens in Comunidad Valenciana (Spain). The software mapping tool developed for this study consisted of three main phases: data collection, data analysis and data representation. To obtain the serological data, the authors analysed 8,520 serum samples from broiler farms over three years. The data were represented on a map of Comunidad Valenciana, including geographical information of flock locations to facilitate disease monitoring. No clinical signs of LPNAI were reported in the studied flocks. The data from this study showed no evidence of contact with LPNAI in broiler flocks and the novel software mapping tool proved a valuable method for easily monitoring on the serological response to avian influenza information, including geographical information.

    The radionuclides 137Cs, 134Cs and 90Sr have been measured in edible tissues and bones of migratory birds (song-thrushes, Turdus philomelos) from central and northern Europe and captured in the Comunidad Valenciana, Spain in the 1994 autumn-winter season. Eight years after the Chernobyl accident, extensive agricultural lands in Europe are still contaminated and this study shows that there was a transfer of radioactive isotopes to the captured migratory song-thrushes. The whole-body dose commitment to humans consuming these birds is estimated.

  9. Estimating Climate Resilience for Conservation across Geophysical Settings

    Conservationists need methods to conserve biological diversity while allowing species and communities to rearrange in response to a changing climate. We developed and tested such a method for northeastern North America that we based on physical features associated with ecological diversity and site resilience to climate change. We comprehensively mapped 30 distinct geophysical settings based on geology and elevation. Within each geophysical setting, we identified sites that were both connected by natural cover and that had relatively more microclimates indicated by diverse topography and elevation gradients. We did this by scoring every 405 ha hexagon in the region for these two characteristics and selecting those that scored >SD 0.5 above the mean combined score for each setting. We hypothesized that these high-scoring sites had the greatest resilience to climate change, and we compared them with sites selected by The Nature Conservancy for their high-quality rare species populations and natural community occurrences. High-scoring sites captured significantly more of the biodiversity sites than expected by chance (p < 0.0001): 75% of the 414 target species, 49% of the 4592 target species locations, and 53% of the 2170 target community locations. Calcareous bedrock, coarse sand, and fine silt settings scored markedly lower for estimated resilience and had low levels of permanent land protection (average 7%). Because our method identifies—for every geophysical setting—sites that are the most likely to retain species and functions longer under a changing climate, it reveals natural strongholds for future conservation that would also capture substantial existing biodiversity and correct the bias in current secured lands. Identificación de Sitios Duraderos para la Conservación Usando la Diversidad del Paisaje y las Conexiones Locales para Estimar la Capacidad de Recuperación al Cambio Climático Resumen Los conservacionistas necesitan un método mediante el cual poder conservar la diversidad biológica mientras permiten que las especies y las comunidades se reorganicen con respecto al clima cambiante. Desarrollamos y probamos tal método, el cual basamos en características físicas asociadas con la diversidad ecológica y la capacidad de recuperación del sitio con respecto al cambio climático, en el noreste de Norteamérica. Mapeamos comprensivamente 30 escenarios geofísicos distintos basados en la geología y la elevación. Dentro de cada escenario geofísico identificamos sitios que estaban conectados por una cubierta natural y que tenían relativamente más microclimas indicados por la topografía diversa y los gradientes de elevación. Hicimos esto al puntuar cada hexágono de 450 ha en la región con estas dos características y al seleccionar aquellos que tuvieron una puntuación >SD 0.5 por encima del puntaje combinado promedio para cada escenario. Nuestra hipótesis fue que estos sitios con altas puntuaciones tuvieron la mayor capacidad de recuperación. Los comparamos con los sitios seleccionados por The Nature Conservancy por sus poblaciones de alta calidad de especies raras y sus ocurrencias de comunidades naturales. Los sitios con altos puntajes capturaron significativamente más de los sitios de biodiversidad de lo que se esperaba por casualidad (p < 0.0001): 75% de las 414 especies objetivo, 49% de las 4592 localidades de especies objetivo y 53% de las 2710 localidades de comunidades objetivo. Los escenarios de lecho rocoso calcáreo, arena gruesa y limo fino tuvieron puntos marcadamente más bajos para la capacidad de recuperación estimada y tuvieron niveles bajos de protección permanente de suelo (en promedio 7%). Ya que nuestro método identifica – para cada escenario geofísico – sitios que tienen mayor probabilidad de retener especies y funciones más tiempo bajo un clima cambiante, revela baluartes naturales para la conservación futura que también capturaría biodiversidad existente sustancial y corregiría el sesgo en tierras que actualmente están aseguradas.

    To evaluate the initial results of the oesophagogastric cancer registry developed for the Sociedad Valenciana de Cirugía and the Health Department of the Comunidad Valenciana (Spain). Fourteen of the 24 public hospitals belonging to the Comunidad Valenciana participated. All patients with diagnosis of oesophageal or gastric carcinomas operated from January 2013 to December 2014 were evaluated. Demographic, clinical and pathological data were analysed. Four hundred and thirty-four patients (120 oesophageal carcinomas and 314 gastric carcinomas) were included. Only two hospitals operated more than 10 patients with oesophageal cancer per year. Transthoracic oesophaguectomy was the most frequent approach (84.2%) in tumours localized within the oesophagus. A total gastrectomy was performed in 50.9% patients with gastroesophageal junction (GOJ) carcinomas. Postoperative 30-day and 90-day mortality were 8% and 11.6% in oesophageal carcinoma and 5.9 and 8.6% in gastric carcinoma. Before surgery, middle oesophagus carcinomas were treated mostly (76,5%) with chemoradiotherapy. On the contrary, lower oesophagus and GOJ carcinomas were treated preferably with chemotherapy alone (45.5 and 53.4%). Any neoadjuvant treatment was administered to 73.6% of gastric cancer patients. Half patients with oesophageal carcinoma or gastric carcinoma received no adjuvant treatment. This registry revealed that half patients with oesophageal cancer were operated in hospitals with less than 10 cases per year at the Comunidad Valenciana. Also, it detected capacity improvement for some clinical outcomes of oesophageal and gastric carcinomas. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Modeling Sediment Transport Using a Lagrangian Particle Tracking Algorithm Coupled with High-Resolution Large Eddy Simulations: a Critical Analysis of Model Limits and Sensitivity Som Dutta1, Paul Fischer2, Marcelo H. Garcia11Department of Civil and Environmental Engineering, University of Illinois at Urbana-Champaign, Urbana, Il, 61801 2Department of Computer Science and Department of MechSE, University of Illinois at Urbana-Champaign, Urbana, Il, 61801 Since the seminal work of Niño and Garcia [1994], one-way coupled Lagrangian particle tracking has been used extensively for modeling sediment transport. Over time, the Lagrangian particle tracking method has been coupled with Eulerian flow simulations, ranging from Reynolds Averaged Navier-Stokes (RANS) based models to Detached Eddy Simulations (DES) [Escauriaza and Sotiropoulos, 2011]. Advent of high performance computing (HPC) platforms and faster algorithms have resulted in the work of Dutta et al. [2016], where Lagrangian particle tracking was coupled with high-resolution Large Eddy Simulations (LES) to model the complex and highly non-linear phenomenon of Bulle-Effect at diversions. Despite all the advancements in using Lagrangian particle tracking, there has not been a study that looks in detail at the limits of the model in the context of sediment transport, and also analyzes the sensitivity of the various force formulation in the force balance equation of the particles. Niño and Garcia [1994] did a similar analysis, but the vertical flow velocity distribution was modeled as the log-law. The current study extends the analysis by modeling the flow using high-resolution LES at a Reynolds number comparable to experiments of Niño et al. [1994].

    The astronomy education community has tacitly assumed that learning astronomy is a conceptual domain resting upon spatial thinking skills. As a first step to formally identify an empirical relationship, undergraduate students in a non-major introductory astronomy survey class at a mediumsized, Ph.D. granting, mid-western US university were given pre- and post-astronomy conceptual diagnostics and spatial reasoning diagnostics, Instruments used were the "Test Of Astronomy Standards" and "What Do You Know?" Using only fully matched data for analysis, our sample consisted of 86 undergraduate non-science majors. Students' normalized gains for astronomy surveys were low at .26 and .13 respectively. Students' spatial thinking was measured using an instrument designed specifically for this study. Correlations between the astronomy instruments' pre- to post-course gain scores and the spatial assessment instrument show moderate to strong relationships suggesting the relationship between spatial reasoning and astronomy ability can explain about 25% of the variation in student achievement. La comunidad de educación en astronomía ha supuesto de forma tácita que el aprendizaje de la astronomía consiste en un dominio conceptual fundamentado en el razonamiento espacial. Como un primer paso para identificar formalmente una relación empírica entre estas dos cosas, utilizamos como muestra los estudantes de graduación de carreras no científicas de un curso experimental en una universidad norteamericana del medioeste de porte mediano con programa de Doctorado em curso, en el cual estos estudiantes se sometieron a un diagnóstico de razonamiento espacial y conceptos astronómicos antes e después del mismo. Las herramientas utilizadas fueron el Test Of Astronomy Standards (TOAST) y el cuestionario What do you know? Utilizando solo los datos completamente consistentes para este análisis, nuestra muestra consistió en 86 estudantes de graduación. Las mejoras, depués de normalizadas, en el desempeño de los estudiantes en estos dos asuntos foram pequenas, 0.26 e 0.13 respectivamente. El razonamiento espacial de los estudiantes fue medido utilizando un instrumento específico desarrollado para este trabaljo. Las correlaciones entre los resultados de los tests astronómicos y este instrumento específico, antes y después del curso mostraron una relación entre moderada y fuerte, sugiriendo que la relación entre el razonamiento espacial y el conocimiento astronómico puede explicar hasta un 25% de la variación em el desempeño de los estudiantes.

    Analyze the different contribution of hierarchical categories in the papers published by radiologists of hospitals belonging to Comunidad Valenciana along the period 1994-2001, as well as their distribution in the different journals. For the recovery of the papers sample we have designed specific search profiles for EMI and Medline databases. Hierarchical category of the authors was identified through personal interviews. We have analyzed 417 works, with 1,321 authors distributed in the following form: chief of service, 8.8%; chief of section, 12.4%; assistant physician, 50.7%, and resident, 28%. Hierarchical groupings with participation of residents were more consistent for publishing papers along all the study period (1994-2001). Higher percentage of papers (21%) corresponded to grouping. Radiología was the most productive journal (42% papers). All results were statistically significant (p < 0.0001). Radiodiagnosis residents of Comunidad Valenciana hospitals showed an active participation in research papers published along the period 1994-2001, in collaboration with the rest of the hierarchical categories, basically with the assistant physician. Assistant physicians contributed most of papers. Chief of section and chief of department contributed fifth of papers.

    NASA Astrophysics Data System (ADS)

    Lipkin, Harry J.

    I was at the University of Illinois at Urbana in the academic year 1958-1959 when I first heard about the Mössbauer effect. My contacts with Bardeen and his theory group taught me everything I needed to know about solid state physics to understand the Mössbauer effect. I also learned at Urbana from Fred Seitz that my old friend Kundan Singwi had done pioneering work in neutron scattering which was very relevant to the Mössbauer effect. I had met Kundan and his wife Helga in 1953 when we were both postdocs learning about nuclear energy at Saclay, lived in the same pension operated by the French Atomic Energy Commission, and had dinner together every evening. It was a pleasure to renew our contacts after their arrival at Argonne in 1959 when we were both involved in the Mössbauer effect, and during an extended period while he was at Argonne and we visited every summer. I shall miss both John and Kundan.

    Varios arbovirus han emergido y/o reemergido en el Nuevo Mundo en las últimas décadas. Los virus Zika y chikungunya, anteriormente restringidos a África y quizás Asia, invadieron el continente, causando gran preocupación; además siguen ocurriendo brotes causados por el virus dengue en casi todos los países, con millones de casos por año. El virus West Nile invadió rápidamente América del Norte, y ya se han encontrado casos en América Central y del Sur. Otros arbovirus, como Mayaro y el virus de la encefalitis equina del este han aumentado su actividad y se han encontrado en nuevas regiones. Se han documentado cambios en la patogenicidad de algunos virus que conducen a enfermedades inesperadas. Una fauna diversa de mosquitos, cambios climáticos y en la vegetación, aumento de los viajes, y urbanizaciones no planificadas que generan condiciones adecuadas para la proliferación de Aedes aegypti (L.), Culex quinquefasciatus Say y otros mosquitos vectores, se han combinado para influir fuertemente en los cambios en la distribución y la incidencia de varios arbovirus. Se enfatiza la necesidad de realizar estudios exhaustivos de la fauna de mosquitos y modificaciones de las condiciones ambientales, sobre todo en las zonas urbanas fuertemente influenciadas por factores sociales, políticos y económicos. © The Authors 2017.

  4. Using observed postconstruction peak discharges to evaluate a hydrologic and hydraulic design model, Boneyard Creek, Champaign and Urbana, Illinois

    USGS Publications Warehouse

    Over, Thomas M.; Soong, David T.; Holmes, Robert R.

    2011-01-01

    Boneyard Creek—which drains an urbanized watershed in the cities of Champaign and Urbana, Illinois, including part of the University of Illinois at Urbana-Champaign (UIUC) campus—has historically been prone to flooding. Using the Stormwater Management Model (SWMM), a hydrologic and hydraulic model of Boneyard Creek was developed for the design of the projects making up the first phase of a long-term plan for flood control on Boneyard Creek, and the construction of the projects was completed in May 2003. The U.S. Geological Survey, in cooperation with the Cities of Champaign and Urbana and UIUC, installed and operated stream and rain gages in order to obtain data for evaluation of the design-model simulations. In this study, design-model simulations were evaluated by using observed postconstruction precipitation and peak-discharge data. Between May 2003 and September 2008, five high-flow events on Boneyard Creek satisfied the study criterion. The five events were simulated with the design model by using observed precipitation. The simulations were run with two different values of the parameter controlling the soil moisture at the beginning of the storms and two different ways of spatially distributing the precipitation, making a total of four simulation scenarios. The simulated and observed peak discharges and stages were compared at gaged locations along the Creek. The discharge at one of these locations was deemed to be critical for evaluating the design model. The uncertainty of the measured peak discharge was also estimated at the critical location with a method based on linear regression of the stage and discharge relation, an estimate of the uncertainty of the acoustic Doppler velocity meter measurements, and the uncertainty of the stage measurements. For four of the five events, the simulated peak discharges lie within the 95-percent confidence interval of the observed peak discharges at the critical location; the fifth was just outside the upper end of this interval. For two of the four simulation scenarios, the simulation results for one event at the critical location were numerically unstable in the vicinity of the discharge peak. For the remaining scenarios, the simulated peak discharges over the five events at the critical location differ from the observed peak discharges (simulated minus observed) by an average of 7.7 and -1.5 percent, respectively. The simulated peak discharges over the four events for which all scenarios have numerically stable results at the critical location differs from the observed peak discharges (simulated minus observed) by an average of -6.8, 4.0, -5.4, and 1.5 percent, for the four scenarios, respectively. Overall, the discharge peaks simulated for this study at the critical location are approximately balanced between overprediction and underprediction and do not indicate significant model bias or inaccuracy. Additional comparisons were made by using peak stages at the critical location and two additional sites and using peak discharges at one additional site. These comparisons showed the same pattern of differences between observed and simulated values across events but varying biases depending on streamgage and measurement type (discharge or stage). Altogether, the results from this study show no clear evidence that the design model is significantly inaccurate or biased and, therefore, no clear evidence that the modeled flood-control projects in Champaign and on the University of Illinois campus have increased flood stages or discharges downstream in Urbana.

  5. Assessing ecological correlates of marine bird declines to inform marine conservation

    Identifying drivers of ecosystem change in large marine ecosystems is central for their effective management and conservation. This is a sizable challenge, particularly in ecosystems transcending international borders, where monitoring and conservation of long-range migratory species and their habitats are logistically and financially problematic. Here, using tools borrowed from epidemiology, we elucidated common drivers underlying species declines within a marine ecosystem, much in the way epidemiological analyses evaluate risk factors for negative health outcomes to better inform decisions. Thus, we identified ecological traits and dietary specializations associated with species declines in a community of marine predators that could be reflective of ecosystem change. To do so, we integrated count data from winter surveys collected in long-term marine bird monitoring programs conducted throughout the Salish Sea—a transboundary large marine ecosystem in North America's Pacific Northwest. We found that decadal declines in winter counts were most prevalent among pursuit divers such as alcids (Alcidae) and grebes (Podicipedidae) that have specialized diets based on forage fish, and that wide-ranging species without local breeding colonies were more prone to these declines. Although a combination of factors is most likely driving declines of diving forage fish specialists, we propose that changes in the availability of low-trophic prey may be forcing wintering range shifts of diving birds in the Salish Sea. Such a synthesis of long-term trends in a marine predator community not only provides unique insights into the types of species that are at risk of extirpation and why, but may also inform proactive conservation measures to counteract threats—information that is paramount for species-specific and ecosystem-wide conservation. Evaluación de las Correlaciones Ecológicas de las Declinaciones de Aves Marinas para Informar a la Conservación Marina Resumen La identificación de los conductores del cambio ambiental en los grandes ecosistemas marinos es esencial para su conservación y manejo efectivo. Esto es un reto bastante grande, particularmente en los ecosistemas que trascienden fronteras internacionales, cuando el monitoreo y la conservación de especies migratorias de amplio rango y sus hábitats son logística y financieramente problemáticos. En este caso, usando herramientas tomadas de la epidemiología, elucidamos conductores comunes subyacentes en la declinación de especies dentro de un ecosistema marino, muy similar a cómo los análisis epidemiológicos evalúan los factores de riesgo para los resultados de salud negativos e informar mejor sus decisiones. Con esto, identificamos los rasgos ecológicos y las especializaciones de dieta asociados con la declinación de especies en una comunidad de depredadores marinos que podría ser un reflejo de cambios ambientales. Para lograr esto, integramos datos de conteo de programas de censos de invierno recolectados a lo largo de monitoreos a largo plazo de aves marinas llevados a cabo en el mar Salish – un gran ecosistema marino que trasciende fronteras en el noroeste del Océano Pacífico. Encontramos que las declinaciones por década en los conteos de invierno fueron más prevalentes entre los pescadores de persecución, como los álcidos (Alcidae) y los zambullidores (Podicipedidae), que tienen dietas especializadas basadas en peces forrajeros y que las especies con distribución amplia y sin colonias reproductivas locales estaban más predispuestas a estas declinaciones. Mientras que una combinación de factores posiblemente esté causando las declinaciones de especialistas de peces forrajeros, proponemos que los cambios en la disponibilidad de presas de niveles tróficos bajos pueden estar forzando cambios en la extensión invernal de aves pescadoras en el mar Salish. Dicha síntesis de tendencias a largo plazo en una comunidad de depredadores marinos no sólo proporciona percepciones únicas de este tipo de especies que están en riesgo de ser extirpadas y el por qué de esto, sino también puede informar a las medidas de conservación proactivas para contrarrestar amenazas – información que es primordial para la conservación específica de especies y del ecosistema en su totalidad.

    There are an increasing number of researches in science education that affirm the importance of discussions on the "nature of science" in basic education level as well as in teacher training. The history of science applied to education is a way to contextualize epistemological discussions, allowing both the understanding of scientific content and learning about science concepts. We present some reasonably consensual definitions on the nature of science that have been widely discussed by the academic community. We show also some episodes in the history of astronomy which can lead to discussions involving some aspects of the nature of science, and how they can do it. Hay un número creciente de investigaciones en la enseñanza de las ciencias que afirman la importancia de debates sobre la "naturaleza de la ciencia" en la educación básica y formación del profesorado. La historia de la ciencia aplicada a la educación es una manera de contextualizar los debates de la epistemología, lo que permite tanto la comprensión de los contenidos científicos como el aprendizaje de conceptos científicos. En esto trabajo, presentamos algunas definiciones bastante consensuales sobre la naturaleza de la ciencia que han sido ampliamente discutidas por la comunidad académica y mostramos cómo algunos episodios en la historia de la astronomía pueden llevar a discusiones sobre algunos aspectos de la naturaleza de la ciencia.

    Estudio realizado desde el enfoque de la salutogénesis que pretende determinar el sentido de coherencia (SOC) en jóvenes presos de la Comunidad Valenciana en España y elaborar un mapa de activos para la salud dirigido a promover la salud en esta población. Se utilizó el test "SOC-13" y un cuestionario de preguntas abiertas elaborado ad hoc, el cual autocompletaron los internos de 18 a 22 años de edad, de los tres centros penitenciarios de la región. Participaron 124 jóvenes varones (ya que no había ninguna mujer) y se recogieron variables sociodemográficas y penitenciarias. En el análisis cuantitativo, las variables categóricas se expresaron como frecuencias absolutas y relativas; y las cuantitativas, mediante medias con intervalos de confianza (IC) al 95%. Se realizó un estudio comparativo bivariante, utilizando las siguientes pruebas: Student t-test, análisis de variación (ANOVA), Wilcoxon y Ji-cuadrado. Del cuestionario de preguntas abiertas, se realizó un análisis cualitativo descriptivo temático de los activos identificados, clasificándolos en: internos (recursos personales, en relación con los demás y capacidad para realizar comportamientos saludables) y externos (personas, grupos, instituciones y espacios físicos, situados tanto dentro como fuera de prisión). La edad media fue de 21,1 años (IC 95%: 20,8-21,3); y el SOC de 52,4 (IC 95%: 50,5-54,3), de entre un valor mínimo de 13 y máximo de 91 para la prueba. Los internos del centro penitenciario que ofrecía más actividades escolares y deportivas obtuvieron una puntuación mayor en la dimensión de significatividad del SOC ( p = 0,024), y los internos inmigrantes presentaron un SOC superior ( p = 0,037) a los españoles, en los tres centros. Los jóvenes identificaron los activos internos que cualitativamente se vinculan con las dimensiones de comprensibilidad, manejabilidad y significatividad del SOC; y los activos externos, sobre todo los amigos, familiares y espacios relacionados con la actividad físico-deportiva, tanto dentro como fuera de prisión. Estos activos y sus interrelaciones podrían incorporarse al diseño de futuras intervenciones de promoción de la salud.

    2016-07-29

    Mumps is an acute viral disease characterized by fever and swelling of the parotid or other salivary glands. On May 1, 2015, the Illinois Department of Public Health (IDPH) confirmed a mumps outbreak at the University of Illinois at Urbana-Champaign. IDPH and the Champaign-Urbana Public Health District (C-UPHD) conducted an investigation and identified 317 cases of mumps during April 2015-May 2016. Because of sustained transmission in a population with high 2-dose coverage with measles-mumps-rubella (MMR) vaccine, a third MMR dose was recommended by IDPH, C-UPHD, and the university's McKinley Health Center. No formal recommendation for or against the use of a third MMR dose has been issued by the Advisory Committee on Immunization Practices (ACIP) (1). However, CDC has provided guidelines for use of a third dose as a control measure during mumps outbreaks in settings in which persons are in close contact with one another, where transmission is sustained despite high 2-dose MMR coverage, and when traditional control measures fail to slow transmission (2).

    Objetivo Estimar el efecto del Seguro Popular (SP) sobre la incidencia del gasto catastrófico en salud (GCS) y sobre el gasto de bolsillo en salud (GBS) en el mediano plazo. Material y métodos Con base en la Encuesta de Evaluación del Seguro Popular (2005–2008), se analizaron los resultados del efecto del SP en la cohorte rural para dos años de seguimiento (2006 y 2008) y en la cohorte urbana para un año (2008). Resultados A nivel conglomerado no se detectaron efectos del SP. A nivel hogar se encontró que el SP tiene un efecto protector en el GCS y en el GBS en consulta externa y hospitalización en zonas rurales; y efectos significativos en la reducción de GBS en consulta externa en zonas urbanas. Conclusiones El SP se muestra como un programa efectivo para proteger a los hogares contra gastos de bolsillo por motivos de salud en el mediano plazo. PMID:22282205

  8. Investigation of the winds and electron concentration variability in the D region of the ionosphere by the partial-reflection radar technique

    Weiland, R. M.; Bowhill, S. A.

    1981-01-01

    The development and first observations of the partial-reflection drifts experiment at Urbana, Illinois (40 N) are described. The winds data from the drifts experiment are compared with electron concentration data obtained by the differential-absorption technique to study the possible meteorological causes of the winter anomaly in the mesosphere at midlatitudes. winds data obtained by the meteor-radar experiment at Urbana are also compared with electron concentration data measured at Urban. A significant correlation is shown is both cases between southward winds and increasing electron concentration measured at the same location during winter. The possibility of stratospheric/mesospheric coupling is investigated by comparing satellite-measured 0.4 mbar geopotential data with mesospheric electron concentration data. No significant coupling was observed. The winds measured at Saskatoon, Saskatchewan (52 N) are compared with the electron concentrations measured at Urban, yielding constant fixed relationship, but significant correlations for short segments of the winter. A significant coherence is observed at discrete frequencies during segments of the winter.

  9. A new species of big-eared climbing rat, genus Ototylomys (Cricetidae: Tylomyinae), from Chiapas, Mexico

    Abstract An allopatric population of big-eared climbing rats (Ototylomys) from the Northern Highlands of Chiapas, Mexico, is described as a new species. The new taxon is part of a unique montane rainforest community that includes several other endemic species in the limited geographic range between the Río Grijalva and the Central Depression of Chiapas. Several cranial, external, and molecular characters distinguish this new species of big-eared climbing rat from its more widely distributed congener, Ototylomys phyllotis. We performed principal component and discriminate function analyses of cranial measurements, and found that specimens of the new species consistently could be distinguished from other Ototylomys with strong statistical support. Compared with exemplars of Ototylomys from elsewhere in their range, the new species possesses a karyotype that differs by 3 additional biarmed chromosome pairs, is fixed or nearly fixed for distinct electromorphs at 12 allozyme loci, and the mean genetic distance exceeds 14%, based on comparisons of the mitochondrial cytochrome b gene between the new species of Ototylomys and representatives of O. phyllotis. The restricted distribution in montane karst rainforest suggests that the species and its habitat may be a matter of conservation concern. Una población alopátrica de rata orejuda trepadora (Ototylomys) de las Tierras Altas del Norte de Chiapas, México se describe como una nueva especie. El nuevo taxón es parte de una comunidad única de bosque lluvioso montano que incluye varias especies endémicas en el área de distribución geográfica limitada entre el Río Grijalva y la Depresión Central de Chiapas. Varios caracteres craneales, externos, y moleculares distinguen la nueva rata orejuda trepadora de su congénere más ampliamente distribuido, Ototylomys phyllotis. Se realizaron análisis de componentes principales y de función discriminante de los caracteres craneales, y se encontró que los especímenes de La Pera fueron consistentemente distinguidos de otros Ototylomys con un fuerte soporte estadístico. En comparación con ejemplares de Ototylomys del rango, la nueva especie posee un cariotipo que difiere por 3 pares adicionales de cromosomas biarmados, está fijo o casi fijo por distintos electromorfos en 12 loci alozímicos. Adicionalmente, la media de la distancia genética comparada del gen mitochondrial citocromo b entre la nueva especie de Ototylomys y representantes de O. phyllotis, excede el 14%. La distribución restringida en el bosque lluvioso montano kárstico sugiere que la especie y su hábitat pueden ser de importancia para la conservación. PMID:29674786

    Introducción. Las enfermedades transmitidas por vectores representan más de 17 % de todas las enfermedades infecciosas y causan anualmente un millón de defunciones a nivel mundial. En Colombia, la malaria, el dengue, la enfermedad de Chagas y las leishmaniasis son condiciones endemoepidémicas persistentes.Objetivo. Determinar el comportamiento epidemiológico de las enfermedades transmitidas por vectores en zonas urbanas y rurales de Colombia entre 1990 y 2016.Materiales y métodos. Se hizo un estudio descriptivo del comportamiento epidemiológico de las principales enfermedades transmitidas por vectores en zonas urbanas y rurales de Colombia entre 1990 y 2016, con la información proveniente de fuentes oficiales secundarias.Resultados. En el periodo estudiado se registraron 5'360.134 casos de enfermedades transmitidas por vectores, de los cuales 54,7 % fueron de malaria y 24,9 % de dengue. Estos casos concentraron el 80 % de la carga acumulada de casos de enfermedades transmitidas por vectores. Las medianas de las tasas de incidencia fueron 1.371 y 188 por 100.00 habitantes para malaria y dengue, respectivamente. Además, los casos de chikungunya fueron 774.831 desde su introducción en el 2014 y, los de Zika, 117.674 desde su aparición en 2015. En las zonas rurales predominaron las enfermedades parasitarias transmitidas por vectores como la malaria, las leishmaniasis y la enfermedad de Chagas. A nivel urbano, predominaron el dengue, el chikungunya y el Zika.Conclusiones. La transmisión en Colombia de estas enfermedades es persistente en las zonas urbanas y en las rurales, y de tipo endemoepidémico en los casos de malaria, dengue, leishmaniasis y enfermedad de Chagas. Dicha transmisión se ha dado de manera focalizada y con patrones variables de intensidad. Asimismo, se mantienen las condiciones que han favorecido la transmisión emergente de nuevas arbovirosis.

  12. The integration of environmental geology methods and concepts within the framework of a regional administration; the case of the Comunidad Valenciana, Spain

    NASA Astrophysics Data System (ADS)

    Aurenheimer, C.

    The process of transfer of jurisdictions on environmental matters from the central administration to an autonomous regional government is described. The main approaches taken by different autonomous regions in Spain, to deal with the problems of setting up an environmental administrative organization are also briefly commented here. Finally, the specific structure of the environmental administration in the Comunidad Valenciana and the main guidelines of its environmental policies are explained. It is concluded that earth science can provide a very useful basis for the drafting of these policies in the region, because of the specific nature of the problems to be dealt with, related mainly to water management, soil conservation, land occupation, natural hazards and preservation of natural areas.

    Fibromyalgia is an idiopathic chronic condition that causes widespread musculoskeletal pain, hyperalgesia and allodynia. This review aims to approach the general epidemiology of fibromyalgia according to the most recent published studies, identifying the general worldwide prevalence of the disease, its basic epidemiological profiles and its economic costs, with specific interest in the Spanish and Comunidad Valenciana cases. Fibromyalgia affects, on average, 2.10% of the world's population; 2.31% of the European population; 2.40% of the Spanish population; and 3.69% of the population in the Comunidad Valenciana. It supposes a painful loss of the quality of life of the people who suffer it and the economic costs are enormous: in Spain is has been estimated at more than 12,993 million euros annually.

    Legionella pneumophila is associated to recurrent outbreaks in several Comunidad Valenciana (Spain) localities, especially in Alcoi, where social and climatic conditions seem to provide an excellent environment for bacterial growth. We have analysed the nucleotide sequences of three loci from 25 environmental isolates from Alcoi and nearby locations sampled over 3 years. The analysis of these isolates has revealed a substantial level of genetic variation, with consistent patterns of variability across loci, and comparable to that found in a large, European-wide sampling of clinical isolates. Among the tree loci studied, fliC showed the highest level of nucleotide diversity. The analysis of isolates sampled in different years revealed a clear differentiation, with samples from 2001 being significantly distinct from those obtained in 2002 and 2003. Furthermore, although linkage disequilibrium measures indicate a clonal nature for population structure in this sample, the presence of some recombination events cannot be ruled out.

    Amyotrophic lateral sclerosis (ALS) requires complex multidisciplinary attention. Clinical pathways are assistance plans for certain diseases with a predictable course. These plans are established in isolated centers, not in multicenter regions. The aim is to develop a clinical pathway capable of organizing and homogenizing assistance given in ALS Assistance Network-Comunidad de Madrid which is made up of five hospitals, from the beginning until the end of the disease. In successive meetings, neurologists of these hospitals and members of the Madrid Health Service evaluated published therapeutic guidelines and other documents used in ALS assistance. A clinical pathway was developed adapting this information to social-health care conditions in the Comunidad de Madrid following the FOCUS-PDCA model. A clinical pathway was created consisting of a scientist-technical framework which arranges the attention in relationship to the diagnosis and treatment, according to the degree of disease progression and a chronogram. This is accompanied by several patient information documents on the disease and the tests that are required, and a patient assistance evaluation form. The standards are established to reach and to promote 354 constant improvement in patient care. Clinical pathway for the ALS assistance in a regional network organizes the attention and cares that the patients must receive from the beginning to the end of the disease. This arrangement and homogenization of the attention improves the quality of patient care, diminishes variability and rationalizes the use of the health care resources.

  17. Downstream of downtown: urban wastewater as groundwater recharge

    NASA Astrophysics Data System (ADS)

    Foster, S. S. D.; Chilton, P. J.

    Wastewater infiltration is often a major component of overall recharge to aquifers around urban areas, especially in more arid climates. Despite this, such recharge still represents only an incidental (or even accidental) byproduct of various current practices of sewage effluent handling and wastewater reuse. This topic is reviewed through reference to certain areas of detailed field research, with pragmatic approaches being identified to reduce the groundwater pollution hazard of these practices whilst attempting to retain their groundwater resource benefit. Since urban sewage effluent is probably the only `natural resource' whose global availability is steadily increasing, the socioeconomic importance of this topic for rapidly developing urban centres in the more arid parts of Asia, Africa, Latin America and the Middle East will be apparent. L'infiltration des eaux usées est souvent la composante essentielle de toute la recharge des aquifères des zones urbaines, particulièrement sous les climats les plus arides. Malgré cela, une telle recharge ne constitue encore qu'un sous-produit incident, ou même accidentel, de pratiques courantes variées du traitement de rejets d'égouts et de réutilisation d'eaux usées. Ce sujet est passé en revue en se référant à certaines régions étudiées en détail, par des approches pragmatiques reconnues pour permettre de réduire les risques de pollution des nappes dues à ces pratiques tout en permettant d'en tirer profit pour leur ressource en eau souterraine. Puisque les effluents d'égouts urbains sont probablement la seule « ressource naturelle » dont la disponibilité globale va croissant constamment, l'importance socio-économique de ce sujet est évidente pour les centres urbains à développement rapide de l'Asie, de l'Afrique, de l'Amérique latine et du Moyen-Orient. La infiltración de aguas residuales es a menudo un componente principal de la recarga total en acuíferos ubicados en torno a zonas urbanas, especialmente en los climas más áridos. A pesar de ello, dicho componente todavía es una consecuencia secundaria (o incluso accidental) de diversas prácticas asociadas con la manipulación de las aguas residuales y con la reutilitzación de aguas depuradas. Este tema se revisa mediante referencias a ciertas áreas en las que existen investigación detallada de campo, identificando enfoques pragmáticos con el fin de reducir el riesgo de contaminación de las aguas subterráneas por tales prácticas, a la vez tratando de conservar los beneficios para los recursos del acuífero. Dado que los efluentes de aguas residuales urbanas son probablemente la única `fuente natural' cuya disponibilidad global se halla en del aumento, la importancia socioeconómica de este tema será evidente para los centros urbanos de rápido desarrollo en Asia, Latinoamérica y Oriente Medio.

  18. Rayleigh lidar observations of gravity wave activity in the upper stratosphere at Urbana, Ill.

    NASA Technical Reports Server (NTRS)

    Gardner, C. S.; Miller, M. S.; Liu, C. H.

    1988-01-01

    During 13 nights of Rayleigh lidar measurements at Urbana, Ill. in 1984 to 1986, thirty-six quasi-monochromatic gravity waves were observed in the 35 to 50 km altitude region of the stratosphere. The characteristics of the waves are compared with other lidar and radar measurements of gravity waves and the theoretical models of wave saturation and dissipation phenomena. The measured vertical wavelengths ranged from 2 to 11.5 km and the measured vertical phase velocities ranged from 10 to 85 cm/s. The vertical wavelengths and vertical phase velocities were used to infer observed wave periods which ranged from 100 to 1000 min and horizontal wavelengths which ranged from 70 to 2000 km. Dominant wave activity was found at vertical wavelengths between 2 to 4 km and 7 to 10 km. No significant seasonal variations were evident in the observed parameters. Vertical and horizontal wavelengths showed a clear tendency to increase with wave periods, which is consistent with recent sodium lidar studies of quasi-monochromatic waves near the mesopause. An average amplitude growth length of 20.9 km for the rms wind perturbations was estimated from the data. Kinetic energy density associated with the waves decreased with height, suggesting that waves in this altitude region were subject to dissipation or saturation effects.

  19. Intrinsic Charge Transport in Organic Field-Effect Transistors

    NASA Astrophysics Data System (ADS)

    Podzorov, Vitaly

    2005-03-01

    Organic field-effect transistors (OFETs) are essential components of modern electronics. Despite the rapid progress of organic electronics, understanding of fundamental aspects of the charge transport in organic devices is still lacking. Recently, the OFETs based on highly ordered organic crystals have been fabricated with innovative techniques that preserve the high quality of single-crystal organic surfaces. This technological progress facilitated the study of transport mechanisms in organic semiconductors [1-4]. It has been demonstrated that the intrinsic polaronic transport, not dominated by disorder, with a remarkably high mobility of ``holes'' μ = 20 cm^2/Vs can be achieved in these devices at room temperature [4]. The signatures of the intrinsic polaronic transport are the anisotropy of the carrier mobility and an increase of μ with cooling. These and other aspects of the charge transport in organic single-crystal FETs will be discussed.

  20. Study of 11Li+p elastic scattering using BHF formalism with three body force

    NASA Astrophysics Data System (ADS)

    Sharma, Manjari; Haider, W.

    2018-04-01

    In the present work we have analyzed the elastic scattering data of 11Li + p at 62, 68.4 and 75 MeV/nucleon, using the microscopic optical potential calculated within the framework of Brueckner-Hartree-Fock formalism (BHF). The calculation uses Argonne v18 and Urbana v14 inter-nucleon potentials and the Urbana IX (UVIX) model of three body force. The required nucleon-density distributions for 11Li are obtained using the semi-phenomenological model for nuclear density distributions. The optical potential has been obtained by folding the g-matrices as calculated in BHF (with and without three body forces) over the nucleon density distributions. We have used the exact method for calculating both the direct and the exchange parts of the spin-orbit potential. Our results reveal that the spin-orbit potential significantly contributes to 11Li+p elastic scattering at all three incident energies. Further, the calculated spin-orbit potential in BHF is much smaller and more diffused as compared with the phenomenological spin-orbit potential. The analysis reveals that the calculated microscopic optical potentials, with and without three body force using BHF approach with phenomenological form of density distribution, provides satisfactory agreement with the elastic scattering data for 11Li+p.

    Cooper, T.C.

    A visit was made to the Frit Bagging Operation at the Chi-Vit Corporation located at Urbana, Ohio for the purpose of examining methods used at this facility to control worker exposure to hazardous materials during the production of various frits. Frit was the basic material for porcelain enamel used in major appliance finishes. The three major raw materials used to produce frit were soda-ash, borax, and silica-flour. In the manufacturing area batching, mixing, smelting, and bagging take place. All new employees were given a preemployment physical. An annual hearing evaluation was performed for all workers. Ventilation was provided throughout themore » operation. Each weight bin in the batching area was equipped with exhaust ventilation. The frit was moved by a vibration conveyor between smelter and bagger and passed under three exhaust hoods to remove airborne dust during this last portion of this transfer. A small capture hood at the packer unit removed airborne dust generated as material falls from the slide gate to the packer spout. The disposal of the bags was carried out in a very satisfactory manner. The author concludes that the controls used provided an exemplary work environment. The author recommends that an in-depth survey be conducted at this site.« less

    Resumen El VIH es un problema de salud importante dentro de la comunidad latina de los Estados Unidos. Gracias a los esfuerzos de prevención, los niveles de contagio entre los latinos se han mantenido estables por más de una década. Sin embargo, esta población sigue siendo afectada a niveles muy altos, en particular entre hombres que tienen sexo con hombres (HSH), de origen latino y que hablan principalmente el idioma español. Existen varios factores que contribuyen a la transmisión del VIH entre esta población, como son: el uso de drogas; la violencia dentro de la pareja; la presencia de infecciones de transmisión sexual; relaciones sexuales sin protección, dentro y fuera de la pareja; el evadir la búsqueda de recursos (prueba y tratamiento adecuado) por temor a ser discriminado o por su estatus migratorio; la escasez de recursos económicos o estado de pobreza y los patrones relacionados a la migración. En particular, Investigaciones Epidemiológicas de Comportamientos han determinado: cómo algunas dinámicas en parejas están directamente asociadas a los comportamientos sexuales de riesgos. En consecuencia, es necesaria mayor investigación para identificar esas dinámicas, y a su vez, realizar intervenciones dirigidas a la reducción de conductas de riesgo enfocadas en parejas de hombres del mismo sexo. En este escrito, se describe la importancia del uso de las relaciones de pareja como estrategia en la reducción de la trasmisión del VIH/SIDA en HSH de origen latino y que hablan principalmente el idioma español en los Estados Unidos.

  9. Microbial communities in the deep subsurface

    NASA Astrophysics Data System (ADS)

    Krumholz, Lee R.

    The diversity of microbial populations and microbial communities within the earth's subsurface is summarized in this review. Scientists are currently exploring the subsurface and addressing questions of microbial diversity, the interactions among microorganisms, and mechanisms for maintenance of subsurface microbial communities. Heterotrophic anaerobic microbial communities exist in relatively permeable sandstone or sandy sediments, located adjacent to organic-rich deposits. These microorganisms appear to be maintained by the consumption of organic compounds derived from adjacent deposits. Sources of organic material serving as electron donors include lignite-rich Eocene sediments beneath the Texas coastal plain, organic-rich Cretaceous shales from the southwestern US, as well as Cretaceous clays containing organic materials and fermentative bacteria from the Atlantic Coastal Plain. Additionally, highly diverse microbial communities occur in regions where a source of organic matter is not apparent but where igneous rock is present. Examples include the basalt-rich subsurface of the Columbia River valley and the granitic subsurface regions of Sweden and Canada. These subsurface microbial communities appear to be maintained by the action of lithotrophic bacteria growing on H2 that is chemically generated within the subsurface. Other deep-dwelling microbial communities exist within the deep sediments of oceans. These systems often rely on anaerobic metabolism and sulfate reduction. Microbial colonization extends to the depths below which high temperatures limit the ability of microbes to survive. Energy sources for the organisms living in the oceanic subsurface may originate as oceanic sedimentary deposits. In this review, each of these microbial communities is discussed in detail with specific reference to their energy sources, their observed growth patterns, and their diverse composition. This information is critical to develop further understanding of subsurface geochemical processes and to develop new approaches to subsurface remediation. Résumé La diversité des populations et des communautés microbiennes dans le sol et le sous-sol est présentée dans cet article. Les chercheurs s'interrogent fréquemment sur la diversité microbienne du sous-sol, sur les interactions entre organismes et sur les mécanismes qui permettent le maintien des communautés microbiennes souterraines. Il existe des communautés microbiennes anérobies hétérotrophes dans des grès ou dans des sédiments sableux relativement perméables, à proximité de dépôts riches en matières organiques. Ces micro-organismes semblent se maintenir grâce à la consommation de composés organiques provenant des dépôts organiques voisins. Les sources de matériel organique jouant le rôle de donneur d'électrons sont constituées par des sédiments éocènes riches en lignite situés sous la plaine littorale du Texas, les schistes riches en matières organiques du Crétacé du sud-ouest des États-Unis, ainsi que les argiles contenant des matériaux organiques et des bactéries de fermentation de la plaine littorale atlantique. En outre, il existe des communautés fortement diversifiées dans des régions où aucune source de matière organique n'existe, mais où sont présentes des roches ignées. Le sous-sol riche en basalte de la vallée de la Columbia au Canada et les régions granitiques de Suède en sont des exemples. Ces communautés microbiennes souterraines semblent se maintenir par l'action de bactéries lithotrophes se développant grâce à l'hydrogène qui est produit par réactions chimiques dans le sous-sol. Il existe d'autres communautés microbiennes de profondeur dans les sédiments profonds des océans. Ces systèmes sont souvent associés à un métabolisme anérobie et à une réduction des sulfates. La colonisation microbienne s'étend jusqu'à des profondeurs où les températures élevées limitent leur capacité de survie. Les sources d'énergie pour ces organismes vivant dans les fonds des océans peuvent être les dépôts sédimentaires océaniques. Dans cette revue, chacune des communautés microbiennes est discutée en détail en se référant spécifiquement à leurs sources d'énergie, au schéma observé de leur développement et à leur composition diversifiée. Cette information est donnée de façon critique dans le but d'améliorer la compréhension des processus géochimiques intervenant dans le sous-sol et de développer de nouvelles approches pour la dépollution souterraine. Resumen En este artículo se resume la diversidad de las poblaciones y comunidades microbianas en el subsuelo. A partir de exploraciones realizadas en el subsuelo, los científicos se están cuestionando en la actualidad aspectos relativos a la diversidad microbiana, las interacciones entre los distintos microorganismos y los mecanismos para el mantenimiento de las comunidades de microbios. Se ha comprobado la presencia de comunidades microbianas anaerobias y heterótrofas en areniscas relativamente permeables y en sedimentos arenosos ubicados cerca de depósitos ricos en materia orgánica, de la cual se alimentan. Algunas fuentes de material orgánico, que actúan como donantes de electrones, son: sedimentos del Eoceno ricos en lignito, bajo la planicie costera de Texas; pizarras del Cretácico ricas en materia orgánica, al sudoeste del país y arcillas cretácicas con materia orgánica y bacterias fermentativas, en la llanura Atlántica. También existen comunidades microbianas de gran diversidad en rocas ígneas, aunque la fuente de materia orgánica no es tan evidente. Algunos ejemplos son la subsuperficie del valle del Río Columbia, rico en basaltos, y las regiones graníticas de Suecia y Canadá. Estas comunidades microbianas subsuperficiales se mantienen por la acción de bacterias litotrópicas, que crecen en ambiente de H2, generado en la subsuperficie. También existen comunidades microbianas a gran profundidad, como por ejemplo en los sedimentos oceánicos. Estos sistemas subsisten con un metabolismo anaerobio en un ambiente sulfato-reductor. La colonización microbiana se extiende hasta profundidades tales que las altas temperaturas limitan su supervivencia. Las fuentes de energía para estos organismos pueden ser los depósitos sedimentarios oceánicos. En este artículo se discute cada una de estas comunidades en detalle, en particular sus fuentes de energía, su esquema de crecimiento y la diversidad de su composición. Esta información es de gran interés para permitir un mayor entendimiento de los procesos geoquímicos en profundidad y para desarrollar nuevos métodos de rehabilitación.

    this article looks at how the development of community nursing services in China and Hong Kong can enhance universal health coverage. literature and data review have been utilized in this study. nursing services have evolved much since the beginning of the nursing profession. The development of community nursing services has expanded the scope of nursing services to those in need of, not just hospital-level nursing care, but more holistic care to improve health and quality of life. despite the one-country-two-systems governance and the difference in population and geography, Hong Kong and China both face the aging population and its complications. Community nursing services help to pave the road to Universal Health Coverage. este artigo analisa a forma como o desenvolvimento de serviços de enfermagem comunitários na China e Hong Kong pode melhorar a cobertura universal de saúde. literatura e revisão de dados foram utilizados neste estudo. serviços de enfermagem têm evoluído muito desde o início da profissão de enfermagem. O desenvolvimento dos serviços de enfermagem da comunidade ampliou o escopo dos serviços de enfermagem, para aqueles que precisam não apenas de cuidados de enfermagem de nível de hospital, mas cuidados mais holísticos para melhorar a saúde e qualidade de vida. apesar de ser "um-país-dois-sistemas" de governo, e as diferenças de população e geografia, Hong Kong e China enfrentam o envelhecimento da população e suas complicações.

    To describe the methodology used in the process of setting health priorities for community intervention in a community of older adults. Based on the results of a health diagnosis related to active aging, a prioritization process was conceived to select the priority intervention problem. The process comprised four successive phases of problem analysis and classification: (1) grouping by level of similarity, (2) classification according to epidemiological criteria, (3) ordering by experts, and (4) application of the Hanlon method. These stages combined, in an integrated manner, the views of health team professionals, community nursing and gerontology experts, and the actual community. The first stage grouped the identified problems by level of similarity, comprising a body of 19 issues for analysis. In the second stage these problems were classified by the health team members by epidemiological criteria (size, vulnerability, and transcendence). The nine most relevant problems resulting from the second stage of the process were submitted to expert analysis and the five most pertinent problems were selected. The last step identified the priority issue for intervention in this specific community with the participation of formal and informal community leaders: Low Social Interaction in Community Participation. The prioritization process is a key step in health planning, enabling the identification of priority problems to intervene in a given community at a given time. There are no default formulas for selecting priority issues. It is up to each community intervention team to define its own process with different methods/techniques that allow the identification of and intervention in needs classified as priority by the community. Descrever a metodologia utilizada no processo de estabelecimento de prioridades em saúde para intervenção comunitária, numa comunidade idosa. Partindo dos resultados de um diagnóstico de saúde no âmbito da promoção do envelhecimento ativo, concebeu-se um processo de estabelecimento de prioridades a fim de selecionar o problema prioritário para intervenção. O processo integrou quatro etapas sucessivas de análise e classificação dos problemas: (1) agrupamento por nível de similitude, (2) classificação de acordo com critérios epidemiológicos, (3) ordenação por peritos e (4) aplicação do método de Hanlon. No decurso destas etapas, combinaram-se, de forma integrada, as perspetivas dos profissionais da equipe de saúde, de peritos em enfermagem comunitária e gerontologia e da própria comunidade. Na primeira etapa, agruparam-se por nível de similitude os problemas identificados, constituindo-se um corpo de 19 problemas para análise. Na segunda, esses problemas foram classificados pelos elementos da equipe de saúde, mediante a aplicação de critérios de cariz epidemiológico (magnitude, vulnerabilidade e transcendência). Os nove problemas mais relevantes resultantes da operacionalização da segunda etapa do processo foram submetidos a análise por peritos, e selecionados os cinco problemas com maior pertinência de atuação. Na última etapa, com recurso à participação de líderes formais e informais da comunidade, identificou-se o problema prioritário para intervenção nessa comunidade específica: a Baixa Interação Social na Participação Comunitária. O processo de estabelecimento de prioridades é uma etapa fundamental do planejamento em saúde, permitindo identificar os problemas prioritários a intervir numa determinada comunidade e num determinado momento. Não existem fórmulas predeterminadas para a seleção de problemas prioritários. Cabe a cada equipe de intervenção comunitária a definição de um processo próprio com diferentes métodos/técnicas que possibilitem a identificação e intervenção em necessidades classificadas como prioritárias pela comunidade.

  2. Groundwater evolution beneath Hat Yai, a rapidly developing city in Thailand

    Many cities and towns in South and Southeast Asia are unsewered, and urban wastewaters are often discharged either directly to the ground or to surface-water canals and channels. This practice can result in widespread contamination of the shallow groundwater. In Hat Yai, southern Thailand, seepage of urban wastewaters has produced substantial deterioration in the quality of the shallow groundwater directly beneath the city. For this reason, the majority of the potable water supply is obtained from groundwater in deeper semi-confined aquifers 30-50 m below the surface. However, downward leakage of shallow groundwater from beneath the city is a significant component of recharge to the deeper aquifer, which has long-term implications for water quality. Results from cored boreholes and shallow nested piezometers are presented. The combination of high organic content of the urban recharge and the shallow depth to the water table has produced strongly reducing conditions in the upper layer and the mobilisation of arsenic. A simple analytical model shows that time scales for downward leakage, from the surface through the upper aquitard to the semi-confined aquifer, are of the order of several decades. Résumé. De nombreuses villes du sud et du sud-est de l'Asie ne possèdent pas de réseaux d'égouts et les eaux usées domestiques s'écoulent souvent directement sur le sol ou dans des canaux et des cours d'eau de surface. Ces pratiques peuvent provoquer une contamination dispersée de la nappe phréatique. A Hat Yai (sud de la Thaïlande), les infiltrations d'eaux usées domestiques sont responsables d'une détérioration notable de la qualité de la nappe phréatique directement sous la ville. Pour cette raison, la majorité de l'eau potable est prélevée dans des aquifères semi-captifs plus profonds, situés entre 30 et 50 m sous la surface. Cependant, une drainance à partir de la nappe phréatique sous la ville constitue une composante significative de la recharge de l'aquifère plus profond, ce qui aura, à long terme, des implications sur la qualité de l'eau. Les résultats fournis par des forages carottés et des piézomètres peu profonds sont présentés. La combinaison entre une concentration élevée en matières organiques, provenant de la recharge par les eaux usées domestiques, et la faible profondeur de la nappe a produit des conditions fortement réductrices dans le niveau supérieur et une mobilisation de l'arsenic. Un modèle analytique simple montre que les échelles de temps pour la drainance vers le bas, à partir de la surface au travers de l'imperméable supérieur vers l'aquifère semi-captif, sont de l'ordre de quelques dizaines d'années. Resumen. Muchas ciudades en el sur y sudeste de Asia carecen de sistemas de saneamiento, por lo que las aguas residuales urbanas son a menudo vertidas bien directamente al suelo o bien a canales de aguas superficiales. Esta práctica puede provocar la contaminación difusa de las aguas subterráneas someras. En Hat Yai, al sur de Tailandia, la percolación de aguas residuales urbanas ha producido un deterioro substancial de la calidad del acuífero somero sobre el que se sitúa la ciudad. Por ello, la mayor parte del suministro de agua potable se obtiene a partir de aguas subterráneas de acuíferos semiconfinados más profundos, localizados entre 30 y 50 m bajo la superficie. No obstante, el goteo desde el acuífero freático constituye una fracción importante de la recarga al acuífero profundo, hecho que tiene implicaciones en lo que respecta a la calidad del agua a largo plazo. Se presentan en este artículo los resultados de testigos de sondeos y de multi-piezómetros someros. El alto contenido en materia orgánica de las aguas urbanas, unido a la cercanía del nivel freático, ha producido la movilización de arsénico al crearse condiciones altamente reductoras. Un modelo matemático sencillo indica que el tiempo de tránsito desde la superficie hasta el acuífero semiconfinado es del orden de varias décadas.

    2017-01-01

    Just over 10 years ago, we conducted a culture study of the Computer Science Department at the flagship University of Illinois at Urbana-Champaign, one of the top five computing departments in the country. The study found that while the department placed an emphasis on research, it did so in a way that, in conjunction with a lack of communication and transparency, devalued teaching and mentoring, and negatively impacted the professional development, education, and sense of belonging of the students. As one part of a multi-phase case study spanning over a decade, this manuscript presents preliminary findings from our latest work at the university. We detail early comparisons between data gathered at the Department of Computer Science at the University of Illinois at Urbana-Champaign in 2005 and our most recent pilot case study, a follow-up research project completed in 2016. Though we have not yet completed the full data collection, we find it worthwhile to reflect on the pilot case study data we have collected thus far. Our data reveals improvements in the perceptions of undergraduate teaching quality and undergraduate peer mentoring networks. However, we also found evidence of continuing feelings of isolation, incidents of bias, policy opacity, and uneven policy implementation that are areas of concern, particularly with respect to historically underrepresented groups. We discuss these preliminary follow-up findings, offer research and methodological reflections, and share next steps for applied research that aims to create positive cultural change in computing.

  5. Meta-Analysis of Attitudes toward Damage-Causing Mammalian Wildlife

    Many populations of threatened mammals persist outside formally protected areas, and their survival depends on the willingness of communities to coexist with them. An understanding of the attitudes, and specifically the tolerance, of individuals and communities and the factors that determine these is therefore fundamental to designing strategies to alleviate human-wildlife conflict. We conducted a meta-analysis to identify factors that affected attitudes toward 4 groups of terrestrial mammals. Elephants (65%) elicited the most positive attitudes, followed by primates (55%), ungulates (53%), and carnivores (44%). Urban residents presented the most positive attitudes (80%), followed by commercial farmers (51%) and communal farmers (26%). A tolerance to damage index showed that human tolerance of ungulates and primates was proportional to the probability of experiencing damage while elephants elicited tolerance levels higher than anticipated and carnivores elicited tolerance levels lower than anticipated. Contrary to conventional wisdom, experiencing damage was not always the dominant factor determining attitudes. Communal farmers had a lower probability of being positive toward carnivores irrespective of probability of experiencing damage, while commercial farmers and urban residents were more likely to be positive toward carnivores irrespective of damage. Urban residents were more likely to be positive toward ungulates, elephants, and primates when probability of damage was low, but not when it was high. Commercial and communal farmers had a higher probability of being positive toward ungulates, primates, and elephants irrespective of probability of experiencing damage. Taxonomic bias may therefore be important. Identifying the distinct factors explaining these attitudes and the specific contexts in which they operate, inclusive of the species causing damage, will be essential for prioritizing conservation investments. Meta-Análisis de las Posturas hacia la Mamíferos Silvestres Causantes de Daños Resumen Muchas poblaciones de mamíferos amenazados persisten fuera de áreas protegidas formales y su supervivencia depende de la buena voluntad de las comunidades que coexisten con ellos. Un entendimiento de las posturas, y específicamente de la tolerancia, de los individuos y las comunidades y los factores que los determinan es fundamental para diseñar estrategias que alivien el conflicto humano – vida silvestre. Llevamos a cabo un meta-análisis para identificar los factores que afectaron las posturas hacia cuatro grupos de mamíferos terrestres. Los elefantes (65%) provocaron las posturas más positivas. Los siguieron los primates (55%), los ungulados (53%) y los carnívoros (44%). Los residentes urbanos presentaron las posturas más positivas (80%), seguidos por los granjeros comerciales (51%) y los granjeros comunales (26%). Un índice de tolerancia a los daños mostró que la tolerancia humana a los ungulados y primates fue proporcional a la probabilidad de experimentar daños mientras que los elefantes provocaron niveles de tolerancia más altos de lo esperado y los carnívoros provocaron niveles de tolerancia más bajos de lo esperado. Contrario a la sabiduría convencional, experimentar daños no fue siempre el factor dominante para determinar las posturas. Los granjeros comunales tuvieron una baja probabilidad de ser positivos hacia los carnívoros independientemente de la probabilidad de experimentar daños, mientras que los granjeros comerciales y los residentes urbanos tuvieron mayor probabilidad de ser positivos hacia los carnívoros independientemente de los daños. Los residentes urbanos tuvieron mayor probabilidad de ser positivos hacia los ungulados, los elefantes y los primates cuando la probabilidad de daños fue baja, pero no cuando fue alta. Los granjeros comerciales y comunales tuvieron una mayor probabilidad de ser positivos hacia los ungulados, los primates y los elefantes independientemente de la probabilidad de experimentar daños. El prejuicio taxonómico por eso puede ser importante. El identificar los distintos factores que explican estas posturas y los contextos específicos en los cuales operan, inclusivo de especies que causan daños, será esencial para priorizar las inversiones en la conservación.

    2016-08-04

    To explore the pillars of community resilience in a region where Chagas disease is endemic, with the aim of promoting participatory processes to deal with this condition from the resilience of the population. Qualitative study using ethnographic record and six interviews of focus groups with young people, women and men. The research was carried out in a rural area of the state of Morelos, Mexico, between 2006 and 2007. We carried out educational sessions with the population in general, so that residents could identify the relationship between the vector Triatoma pallidipennis, the parasite (Trypanosoma cruzi), symptoms, and preventive actions for Chagas disease. The ethnographic record and groups were analyzed based on Taylor and Bogdan's modification, and the focus was to understand the socio-cultural meanings that guide the speeches and activities of residents in relation to the pillars of community resilience. The population felt proud of belonging to that location and three pillars of community resilience were clearly identified: collective self-esteem, cultural identity, and social honesty. Having these pillars as bases, we promoted the participation of the population concerning Chagas disease, and a Community Action Group was formed with young people, adult men and women, and social leaders. This Group initiated actions of epidemiological and entomological surveillance in the community to deal with this problem. It is necessary to create more experiences that deepen the understanding of the pillars of community resilience, and how they contribute to enhance participation in health to deal with Chagas disease. Explorar los pilares de la resiliencia comunitaria en una región en la que la enfermedad de Chagas es endémica, con la finalidad de partir de la resiliencia de la población para impulsar procesos participativos para enfrentar este padecimiento. Estudio cualitativo que utilizó registro etnográfico y seis entrevistas de grupos focales con jóvenes, mujeres y hombres adultos. La investigación se efectúo en una localidad rural del Estado de Morelos, México, entre 2006 y 2007. Se efectuaron sesiones educativas con la población en general, para que los habitantes identificaran la relación entre el vector Triatoma pallidipennis, el parásito (Trypanosoma cruzi), la sintomatología y acciones preventivas para la enfermedad de Chagas. El registro etnográfico y los grupos fueron analizados con base en una modificación de Taylor y Bogdan, y el foco fue comprender los significados socioculturales que guían los discursos y actividades de los pobladores en relación a los pilares de la resiliencia comunitaria. La población se sentía orgullosa de pertenecer a esa localidad y se identificaron con claridad tres pilares de la resiliencia comunitaria: autoestima colectiva, identidad cultural y honestidad social. Tomando como base estos pilares, se impulsó la participación de la población en torno a la enfermedad de Chagas, y se formó un Grupo de Acción Comunitaria con jóvenes, hombres y mujeres adultos, y líderes sociales. Este Grupo inició acciones de vigilancia epidemiológica y entomológica en la comunidad para hacer frente a esta problemática. Es necesario generar más experiencias que profundicen en la comprensión de los pilares de resiliencia comunitaria, y en la manera en que estos contribuyen a potenciar la participación en salud para enfrentar la enfermedad de Chagas.

    The design, interfacing, testing, and operation of a preprocessor to increase the altitude and temporal resolution of the present coherent-scatter system are described. This system upgrade requires an increase in the data collection rate. Replacing the present, relatively slow, ADC with two high speed ADCs achieves the increased echo sampling rate desired. To stay within the capabilities of the main computer's I/O and processing rate the data must be reduced before transfer to the main computer. Thus the preprocessor also coherently integrates the data before transfer.

    A flexible very high frequency (VHF) stratosphere-troposphere (ST) radar configured for meteorological research is to be constructed near Urbana, Illinois. Measurement of small vertical velocities associated with synoptic-scale meteorology can be performed. A large Doppler microwave radar (CHILL) is located a few km from the site of the proposed ST radar. Since the microwave radar can measure the location and velocity of hydrometeors and the VHF ST radar can measure clear (or cloudy) air velocities, simultaneous observations by these two radars of stratiform or convective weather systems would provide valuable meteorological information.

The coherent scatter radar utilizes a diode array and components from meteor radar. The receiving system permits a time resolution of one minute in the data. Echo power from the D region shows a high degree of variability from day to day. Examples of changes in power level at shorter time scales are observed. Velocity data show the existence of gravity waves and occasionally exhibit vertical standing wave characteristics.

    Long interspersed elements (LINEs) and short interspersed elements (SINEs) are retrotransposons. These elements can mobilize by the "copy-and-paste" mechanism, in which their own RNA is reverse-transcribed into complementary DNA (cDNA). LINEs and SINEs not only are components of eukaryotic genomes but also drivers of genomic evolution. Thus, studies of the amplification mechanism of LINEs and SINEs are important for understanding eukaryotic genome evolution. Here we report the characterization of one LINE family (UnaL2) and two SINE families (UnaSINE1 and UnaSINE2) from the eel (Anguilla japonica) genome. UnaL2 is approximately 3.6 kilobases (kb) and encodes only one open reading frame (ORF). UnaL2 belongs to the stringent type--thought to be a major group of LINEs--and can mobilize in HeLa cells. We also show that UnaL2 and the two UnaSINEs have similar 3' tails, and that both UnaSINE1 and UnaSINE2 can be mobilized by UnaL2 in HeLa cells. These elements are thus useful for delineating the amplification mechanism of stringent type LINEs as well as that of SINEs.

  4. The Use and Interpretation of Sodium Concentrations in Casual (Spot) Urine Collections for Population Surveillance and Partitioning of Dietary Iodine Intake Sources

    PubMed Central

    Conkle, Joel; van der Haar, Frits

    2016-01-01

    In 2013, the World Health Organization (WHO) called for joint surveillance of population salt and iodine intakes using urinary analysis. 24-h urine collection is considered the gold standard for salt intake assessment, but there is an emerging consensus that casual urine sampling can provide comparable information for population-level surveillance. Our review covers the use of the urinary sodium concentration (UNaC) and the urinary iodine concentration (UIC) from casual urine samples to estimate salt intakes and to partition the sources of iodine intakes. We reviewed literature on 24-h urinary sodium excretion (UNaE) and UNaC and documented the use of UNaC for national salt intake monitoring. We combined information from our review of urinary sodium with evidence on urinary iodine to assess the appropriateness of partitioning methods currently being adapted for cross-sectional survey analyses. At least nine countries are using casual urine collection for surveillance of population salt intakes; all these countries used single samples. Time trend analyses indicate that single UNaC can be used for monitoring changes in mean salt intakes. However; single UNaC suffers the same limitation as single UNaE; i.e., an estimate of the proportion excess salt intake can be biased due to high individual variability. There is evidence, albeit limited, that repeat UNaC sampling has good agreement at the population level with repeat UNaE collections; thus permitting an unbiased estimate of the proportion of excess salt intake. High variability of UIC and UNaC in single urine samples may also bias the estimates of dietary iodine intake sources. Our review concludes that repeated collection, in a sub-sample of individuals, of casual UNaC data would provide an immediate practical approach for routine monitoring of salt intake, because it overcomes the bias in estimates of excess salt intake. Thus we recommend more survey research to expand the evidence-base on predicted-UNaE from repeat casual UNaC sampling. We also conclude that the methodology for partitioning the sources of iodine intake based on the combination of UIC and UNaC measurements in casual urine samples can be improved by repeat collections of casual data; which helps to reduce regression dilution bias. We recommend more survey research to determine the effect of regression dilution bias and circadian rhythms on the partitioning of dietary iodine intake sources. PMID:28025546

    Although practical training has always been important in Nursing, it has reached a new dimension in the European Higher Education Area. This has involved adapting the syllabus, where one of the new features is considering clinical practice as an independent subject and also including the concept of competence as a result of the students' learning. The figure of the tutor becomes one of the key factors and therefore their activities and competencies must be defined. To enumerate and prioritize, by agreement, the main activities and competences by the tutor of clinical practices in the Comunidad Autónoma de Madrid should posses. METHODOLOGY. Quantitative focus, analysis by group of experts between 2010 and 2013. RESULTS. A total of 510 nurses have participated, 17 panels of experts have met and consensus has been reached on 22 competencies and 12 activities. The description of activities and competencies can be extremely useful for selecting, evaluating and developing nursing clinical practice tutors, becoming a baseline and reducing the subjectivity in the development of tutors according to the new demands of the European Higher Education Area.

    The intrinsic vulnerability of groundwater in the Comunidad de Madrid (central Spain) was evaluated using the DRASTIC and GOD indexes. Groundwater vulnerability to nitrate pollution was also assessed using the composite DRASTIC (CD) and nitrate vulnerability (NV) indexes. The utility of these methods was tested by analyzing the spatial distribution of nitrate concentrations in the different aquifers located in the study area: the Tertiary Detrital Aquifer, the Moor Limestone Aquifer, the Cretaceous Limestone Aquifer and the Quaternary Aquifer. Vulnerability maps based on these four indexes showed very similar results, identifying the Quaternary Aquifer and the lower sub-unit of the Moor Limestone Aquifer as deposits subjected to a high risk of nitrate pollution due to intensive agriculture. As far as the spatial distribution of groundwater nitrate concentrations is concerned, the NV index showed the greatest statistical significance ( p < 0.01). This new type of multiplicative model offers greater accuracy in estimations of specific vulnerability with respect to the real impact of each type of land use. The results of this study provide a basis on which to guide the designation of nitrate vulnerable zones in the Comunidad de Madrid, in line with European Union Directive 91/676/EEC.

    A retrospective, population-based registry was established in the Comunidad of Madrid, Spain (total population: 4,780,572; under age 15: 1,105,243) to investigate the epidemiology of Type 1 (insulin-dependent) diabetes mellitus. Included were all cases diagnosed with diabetes between 1985 and 1988, with age onset less than 15 years, and using insulin at discharge from hospital. Using the capture-recapture method employing hospital records as the primary source and membership files of the Spanish Diabetic Association as the secondary source, the ascertainment was 90%. The overall annual incidence was estimated to be 11.3/100,000 (Poison 95% confidence interval: 10.3-12.4). There was no temporal increase in incidence, nor was there a significant sex difference in incidence rates, either overall or by year. The seasonal onset pattern showed the highest incidence in winter (December-February) and lowest in summer (June-August) (r = 7.36, p less than 0.05). The age-adjusted (world standard) incidence of 10.9/100,000 was inconsistent with the hypothesis of a north-south gradient in diabetes risk.

    La primera semana de septiembre de 2013, el Sistema Nacional de Vigilancia Epidemiológica identificó dos casos de cólera en Ciudad de México. Los cultivos de ambas muestras se confirmaron como Vibrio cholerae serogrupo O1, serotipo Ogawa, biotipo El Tor. Los análisis iniciales por electroforesis por campos pulsados y por reacción en cadena de la polimerasa indicaron que ambas cepas eran similares, pero diferentes de las previamente reportadas en México. La semana siguiente se identificaron cuatro casos más en una comunidad del Estado de Hidalgo, ubicada a 121 kilómetros al noreste de Ciudad de México. Posteriormente se inició un brote de cólera en la región de La Huasteca. Los análisis genómicos de cuatro cepas obtenidas en este estudio confirmaron la presencia de las islas de patogenicidad VPI -1 y VPI-2, VSP-1 y VSP-2, y del elemento integrador SXT. La estructura genómica de los cuatro aislamientos fue similar a la de V. cholerae cepa 2010 EL-1786, identificada durante la epidemia en Haití en 2010. Este estudio pone de manifiesto que la epidemiología molecular es una herramienta muy poderosa para vigilar, prevenir y controlar enfermedades de importancia en salud pública en México. The first week of September 2013, the National Epidemiological Surveillance System identified two cases of cholera in Mexico City. The cultures of both samples were confirmed as Vibrio cholerae serogroup O1, serotype Ogawa, biotype El Tor. Initial analyses by pulsed-field gel electrophoresis and by polymerase chain reaction-amplification of the virulence genes, suggested that both strains were similar, but different from those previously reported in Mexico. The following week, four more cases were identified in a community in the state of Hidalgo, located 121 km northeast of Mexico City. Thereafter a cholera outbreak started in the region of La Huasteca. Genomic analyses of the strains obtained in this study confirmed the presence of pathogenicity islands VPI-1 and VPI-2, VSP-1 and VSP-2, and of the integrative element SXT. The genomic structure of the 4 isolates was similar to that of V. cholerae strain 2010 EL-1786, identified during the epidemic in Haiti in 2010. This study shows that molecular epidemiology is a very powerful tool to monitor, prevent and control diseases of public health importance in Mexico. Copyright: © 2017 SecretarÍa de Salud.

    1995-01-01

    This report describes the results of a study to estimate characteristics of base flow and sustained ground-water discharge at five streamflow-gaging stations on the Mad River in Ohio. The five streamflow-gaging stations are located at Zanesfield, near Urbana, at St. Paris Pike (at Eagle City), near Springfield, and near Dayton. The median of the annual-mean base flows, determined by means of hydrograph separation, ranged from 0.64 (ft3/s)/mi2 (cubic feet per second per square mile) at Zanesfield to 0.74 (ft3/s)/mi2 at St. Paris Pike. The median percentage of annual total streamflow attributed to base flow ranged from 61.8 percent at Zanesfield to 76.1 percent near Urbana. Estimates of an upper limit (or threshold) at which base flows can be considered to be composed predominately of sustained ground-water discharge were made by constructing and analyzing base- flow-duration curves. The sustained ground-water discharges (base flows less than or equal to the estimated sustained ground-water-discharge thresholds) are assumed to originate from ground-water- flow systems that are minimally affected by seasonal climatic changes. The median sustained ground- water discharge ranged from 0.11 (ft3/s)/mi2 at Zanesfield to 0.26 (ft3/s)/mi2 at St. Paris Pike (at Eagle City) and near Springfield. The median sustained ground-water discharge, expressed as a percentage of the median annual-mean base flow, ranged from 17.2 percent at Zanesfield to 38.6 percent near Springfield.

    2010-01-01

    Thermodynamics provides insights into the influence of modified nucleotide residues on stability of nucleic acids and is crucial for designing duplexes with given properties. In this article, we introduce detailed thermodynamic analysis of RNA duplexes modified with unlocked nucleic acid (UNA) nucleotide residues. We investigate UNA single substitutions as well as model mismatch and dangling end effects. UNA residues placed in a central position makes RNA duplex structure less favourable by 4.0–6.6 kcal/mol. Slight destabilization, by ∼0.5–1.5 kcal/mol, is observed for 5′- or 3′-terminal UNA residues. Furthermore, thermodynamic effects caused by UNA residues are extremely additive with ΔG°37 conformity up to 98%. Direct mismatches involving UNA residues decrease the thermodynamic stability less than unmodified mismatches in RNA duplexes. Additionally, the presence of UNA residues adjacent to unpaired RNA residues reduces mismatch discrimination. Thermodynamic analysis of UNA 5′- and 3′-dangling ends revealed that stacking interactions of UNA residues are always less favourable than that of RNA residues. Finally, circular dichroism spectra imply no changes in overall A-form structure of UNA–RNA/RNA duplexes relative to the unmodified RNA duplexes. PMID:20562222

    Sodium intake is an important issue for patients with chronic kidney disease (CKD). The two most widely used methods to measure sodium are 24-h urinary sodium excretion (24HUNa), which can be difficult to perform routinely, and sodium intake by dietary recall, which can be inaccurate. This study evaluated use of the mean value of three spot urinary sodium (UNa) concentrations to estimate daily sodium intake in patients with CKD. This cross-sectional study enrolled 305 patients with CKD, none of whom were on dialysis, who visited the nephrology clinic at the Asan Medical Center (Seoul, Korea). We performed three spot UNa tests, three calculations of the UNa/creatinine (UCr) ratio, one measurement of 24HUNa, and one measurement of sodium intake by dietary recall. The 24HUNa and mean spot UNa values were significantly lower in patients with more advanced CKD (P = 0.006 and P < 0.001, respectively). One-time spot UNa was significantly higher in the evening than in the morning for patients with stage III, IV, or V CKD. Total sodium intake, but not sodium nutrient density (milligrams of sodium per 1000 kcal), was significantly different for patients with different stages of CKD (P = 0.001). The correlation coefficient between 24HUNa and mean spot UNa was 0.477 (95% confidence interval [CI] 0.384-0.562, P < 0.001), slightly higher than that between 24HUNa excretion and mean spot UNa/UCr (r = 0.313, 95% CI 0.207-0.465, P < 0.001). There was a linear relation between spot UNa and 24HUNa: mean spot UNa = 0.27 × 24HUNa + 60. Therefore, a 24HUNa excretion of 87 mEq (sodium intake 2 g/d) corresponded to a mean spot UNa level of 83 mEq/L. The correlation coefficient between sodium intake and mean spot UNa was 0.435 (95% CI 0.336-0.524, P < 0.001), significantly higher than that between sodium intake and mean spot UNa/UCr (r = 0.197, 95% CI 0.091-0.301, P = 0.001). Mean spot UNa tended to be better correlated with 24HUNa than with sodium intake. Mean spot UNa is a simple and effective method that can be used to monitor sodium intake in patients with CKD. A daily intake of 2 g of sodium corresponds to a mean spot UNa level of approximately 83 mEq/L in patients with CKD. Copyright © 2012 Elsevier Inc. All rights reserved.

    HIV infections are still a very serious concern for public heath worldwide. We have applied molecular evolution methods to study the HIV-1 epidemics in the Comunidad Valenciana (CV, Spain) from a public health surveillance perspective. For this, we analysed 1804 HIV-1 sequences comprising protease and reverse transcriptase (PR/RT) coding regions, sampled between 2004 and 2014. These sequences were subtyped and subjected to phylogenetic analyses in order to detect transmission clusters. In addition, univariate and multinomial comparisons were performed to detect epidemiological differences between HIV-1 subtypes, and risk groups. The HIV epidemic in the CV is dominated by subtype B infections among local men who have sex with men (MSM). 270 transmission clusters were identified (>57% of the dataset), 12 of which included ≥10 patients; 11 of subtype B (9 affecting MSMs) and one (n = 21) of CRF14, affecting predominately intravenous drug users (IDUs). Dated phylogenies revealed these large clusters to have originated from the mid-80s to the early 00 s. Subtype B is more likely to form transmission clusters than non-B variants and MSMs to cluster than other risk groups. Multinomial analyses revealed an association between non-B variants, which are not established in the local population yet, and different foreign groups.

  11. Assessing composition and structure of soft biphasic media from Kelvin-Voigt fractional derivative model parameters

    2017-03-01

    Kelvin-Voigt fractional derivative (KVFD) model parameters have been used to describe viscoelastic properties of soft tissues. However, translating model parameters into a concise set of intrinsic mechanical properties related to tissue composition and structure remains challenging. This paper begins by exploring these relationships using a biphasic emulsion materials with known composition. Mechanical properties are measured by analyzing data from two indentation techniques—ramp-stress relaxation and load-unload hysteresis tests. Material composition is predictably correlated with viscoelastic model parameters. Model parameters estimated from the tests reveal that elastic modulus E 0 closely approximates the shear modulus for pure gelatin. Fractional-order parameter α and time constant τ vary monotonically with the volume fraction of the material’s fluid component. α characterizes medium fluidity and the rate of energy dissipation, and τ is a viscous time constant. Numerical simulations suggest that the viscous coefficient η is proportional to the energy lost during quasi-static force-displacement cycles, E A . The slope of E A versus η is determined by α and the applied indentation ramp time T r. Experimental measurements from phantom and ex vivo liver data show close agreement with theoretical predictions of the η -{{E}A} relation. The relative error is less than 20% for emulsions 22% for liver. We find that KVFD model parameters form a concise features space for biphasic medium characterization that described time-varying mechanical properties. The experimental work was carried out at the Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA. Methodological development, including numerical simulation and all data analysis, were carried out at the school of Life Science and Technology, Xi’an JiaoTong University, 710049, China.

    I servizi sono oramai centrali nella vita sociale di ogni Paese. L'aspettativa di ogni attore sociale, sia esso cittadino/utente e/o istituzione, è quella di ricevere da uno scambio che ha alla base un servizio un contributo che si caratterizza per una qualità intrinseca. Il mantenimento di tale promessa richiede all'azienda erogatrice un forte coinvolgimento, nel disegno del servizio, degli utenti ed una capacità di gestione della conoscenza; ciò è particolarmente significativo per quei servizi che si caratterizzano per una forte personalizzazione o complessità progettuale. Disegnare un servizio, metterlo in produzione e gestirne l'erogazione ha una complessità variabile in base al grado di coinvolgimento dei destinati ed alle dimensioni critiche che esprimono le condizioni di fattibilità di un servizio di qualità appropriato alle attese degli utilizzatori. Ugualmente la globalizzazione dell'economia e la scarsità delle risorse ha portato l'attenzione, ai fini della sostenibilità delle condizioni sopra richiamate, di una ricerca di modelli e strumenti che permettano una valutazione e una standardizzazione dei processi di produzione ed erogazione secondo condizioni di economicità. Tali primi e sintetici elementi hanno condotto diversi attori istituzionali, grandi imprese ed università attraverso i loro centri di ricerca, ad una azione di riflessione sul grado di "ingegnerizzazione" dei processi sottesi alla erogazione dei servizi ed in particolare ai servizi che attuano le politiche dei grandi settori di base dell'economia di una Nazione: educazione, sanità, sociale, sviluppo infrastrutture ecc.

  13. Chronic respiratory disease in adults treated for tuberculosis in Khartoum, Sudan

    PubMed Central

    Mortimer, K.; Bjune, G.; El Sony, A. I.

    2016-01-01

    Background: Chronic respiratory disease (CRD) causes substantial morbidity and mortality. Although the global CRD epidemic collides with the tuberculosis (TB) epidemic in many low- and middle-income country settings, the risk of TB-associated CRD is not well described in countries with a high burden of TB. Methods: We recruited 136 patients with a history of sputum smear-positive pulmonary TB (PTB) from the TB clinic at Omdurman Teaching Hospital in Khartoum, Sudan, and 136 age- and sex-matched community controls, between 28 July 2013 and 30 December 2013. Data were collected using standardised questionnaires and spirometry was performed before and after bronchodilator. Results: The mean age of the subjects with previous PTB and controls was respectively 44.0 years (SD 8.5) and 44.5 years (SD 8.6), with 27.2% females in both groups. Chronic respiratory symptoms such as chronic cough (OR 6.67, 95%CI 2.98–14.90, P < 0.001) and the presence of chronic airflow obstruction (OR 12.4, 95%CI 1.56–98.40, P = 0.02) were both strongly associated with a past history of PTB after adjusting for potential confounders. Conclusion: The clinical features of CRDs are strongly associated with past history of PTB. An integrated approach to improve the management of these common conditions should be considered. Contexte : Les maladies respiratoires chroniques (MRC) sont à l'origine d'une morbidité et d'une mortalité considérables dans le monde. Bien que l'épidémie mondiale des MRC entre en conflit avec l'épidémie de tuberculose (TB) dans de nombreux pays à revenu faible ou moyen, le risque de MRC associée à la TB n'est pas bien décrit dans les pays durement frappés par la TB. Méthodes : Nous avons recruté 136 patients ayant des antécédents de tuberculose pulmonaire (TBP) à frottis positif dans le service de pneumologie du Centre Hospitalier Universitaire Omdurman à Khartoum, Soudan, et 136 témoins de la communauté, appariés sur l'âge et le sexe, entre le 28 juillet 2013 et le 30 décembre 2013. Les données ont été recueillies grâce à des questionnaires standardisés ainsi qu'à une spirométrie avant et après bronchodilatateur. Résultats : L'âge moyen des cas et des témoins a été de 44,0 ans (DS 8,5) et 44,5 ans (DS 8,61), respectivement, avec 27,2% de femmes dans les deux groupes. Des symptômes respiratoires chroniques comme une toux chronique (OR 6,67 ; IC95% 2,98–14,90 ; P < 0,001) et la présence d'une obstruction chronique des voies aériennes (OR 12,39 ; IC%95 1,56–98,40 ; P = 0,02) ont été tous deux fortement associés à des antécédents de TBP après ajustement sur les facteurs de confusion potentiels. Conclusion : Les caractéristiques cliniques des MRC sont fortement associées à des antécédents de TBP. Une approche intégrée visant à améliorer la prise en charge de ces pathologies fréquentes devrait être envisagée. Marco de referencia: La enfermedad pulmonar crónica (EPC) es una causa importante de morbilidad y mortalidad. Aunque la epidemia mundial de EPC rivaliza con la epidemia de tuberculosis (TB) en muchos entornos de países con bajos y medianos recursos, el riesgo de aparición de EPC asociado con la TB se ha descrito cabalmente en los países con una alta carga de morbilidad por TB. Métodos: Entre el 28 de julio y el 30 de diciembre del 2013, participaron en el estudio 136 pacientes con antecedente de tuberculosis pulmonar (TBP) y baciloscopia positiva del esputo que habían recibido tratamiento en el consultorio de neumología del Hospital Universitario Omdurman de Jartún, en Sudán, y 136 testigos sanos de la comunidad, emparejados en función de la edad y el sexo. Se recogieron datos mediante cuestionarios normalizados y se practicó una espirometría antes y despuès una prueba de broncodilatación. Resultados: El promedio de la edad en el grupo de los casos fue 44,0 (desviación estándar 8,5 años) y en el grupo de testigos fue 44,5 años (8,6 años); la proporción de mujeres en ambos grupos fue 27,2%. Se observó una fuerte asociación entre la presencia de síntomas respiratorios crónicos como la tos (OR 6,67; IC95% 2,98–14,90; P < 0,001) y la presencia de obstrucción crónica al flujo en las vías respiratorias (OR 12,39; IC95% 1,56–98,40; P = 0,02) en las personas con antecedente de TBP, una vez corregidos los posibles factores de confusión. Conclusión: La presencia de rasgos clínicos de EPC exhibe una fuerte correlación con el antecedente de TBP.

    Background: Chronic respiratory disease (CRD) causes substantial morbidity and mortality. Although the global CRD epidemic collides with the tuberculosis (TB) epidemic in many low- and middle-income country settings, the risk of TB-associated CRD is not well described in countries with a high burden of TB. Methods: We recruited 136 patients with a history of sputum smear-positive pulmonary TB (PTB) from the TB clinic at Omdurman Teaching Hospital in Khartoum, Sudan, and 136 age- and sex-matched community controls, between 28 July 2013 and 30 December 2013. Data were collected using standardised questionnaires and spirometry was performed before and after bronchodilator. Results: The mean age of the subjects with previous PTB and controls was respectively 44.0 years (SD 8.5) and 44.5 years (SD 8.6), with 27.2% females in both groups. Chronic respiratory symptoms such as chronic cough (OR 6.67, 95%CI 2.98-14.90, P < 0.001) and the presence of chronic airflow obstruction (OR 12.4, 95%CI 1.56-98.40, P = 0.02) were both strongly associated with a past history of PTB after adjusting for potential confounders. Conclusion: The clinical features of CRDs are strongly associated with past history of PTB. An integrated approach to improve the management of these common conditions should be considered. Contexte : Les maladies respiratoires chroniques (MRC) sont à l'origine d'une morbidité et d'une mortalité considérables dans le monde. Bien que l'épidémie mondiale des MRC entre en conflit avec l'épidémie de tuberculose (TB) dans de nombreux pays à revenu faible ou moyen, le risque de MRC associée à la TB n'est pas bien décrit dans les pays durement frappés par la TB. Méthodes : Nous avons recruté 136 patients ayant des antécédents de tuberculose pulmonaire (TBP) à frottis positif dans le service de pneumologie du Centre Hospitalier Universitaire Omdurman à Khartoum, Soudan, et 136 témoins de la communauté, appariés sur l'âge et le sexe, entre le 28 juillet 2013 et le 30 décembre 2013. Les données ont été recueillies grâce à des questionnaires standardisés ainsi qu'à une spirométrie avant et après bronchodilatateur. Résultats : L'âge moyen des cas et des témoins a été de 44,0 ans (DS 8,5) et 44,5 ans (DS 8,61), respectivement, avec 27,2% de femmes dans les deux groupes. Des symptômes respiratoires chroniques comme une toux chronique (OR 6,67 ; IC95% 2,98-14,90 ; P < 0,001) et la présence d'une obstruction chronique des voies aériennes (OR 12,39 ; IC%95 1,56-98,40 ; P = 0,02) ont été tous deux fortement associés à des antécédents de TBP après ajustement sur les facteurs de confusion potentiels. Conclusion : Les caractéristiques cliniques des MRC sont fortement associées à des antécédents de TBP. Une approche intégrée visant à améliorer la prise en charge de ces pathologies fréquentes devrait être envisagée.

    Objective. Sodium intake is associated with cardiovascular outcomes. However, no study has specifically reported an association between cardiovascular mortality and urinary sodium concentration (UNa). We examined the association of UNa with mortality in a cohort of type 2 diabetes (T2D) patients. Methods. Patients were followed for all-cause death and cardiovascular death. Baseline UNa was measured from second morning spot urinary sample. We used Cox proportional hazard models to identify independent predictors of mortality. Improvement in prediction of mortality by the addition of UNa to a model including known risk factors was assessed by the relative integrated discrimination improvement (rIDI) index. Results. Participants (n = 1,439) were followed for a median of 5.7 years, during which 254 cardiovascular deaths and 429 all-cause deaths were recorded. UNa independently predicted all-cause and cardiovascular mortality. An increase of one standard deviation of UNa was associated with a decrease of 21% of all-cause mortality and 22% of cardiovascular mortality. UNa improved all-cause and cardiovascular mortality prediction beyond identified risk factors (rIDI = 2.8%, P = 0.04 and rIDI = 4.6%, P = 0.02, resp.). Conclusions. In T2D, UNa was an independent predictor of mortality (low concentration is associated with increased risk) and improved modestly its prediction in addition to traditional risk factors.

  4. Microbial populations in contaminant plumes

    NASA Astrophysics Data System (ADS)

    Haack, Sheridan K.; Bekins, Barbara A.

    Efficient biodegradation of subsurface contaminants requires two elements: (1) microbial populations with the necessary degradative capabilities, and (2) favorable subsurface geochemical and hydrological conditions. Practical constraints on experimental design and interpretation in both the hydrogeological and microbiological sciences have resulted in limited knowledge of the interaction between hydrogeological and microbiological features of subsurface environments. These practical constraints include: (1) inconsistencies between the scales of investigation in the hydrogeological and microbiological sciences, and (2) practical limitations on the ability to accurately define microbial populations in environmental samples. However, advances in application of small-scale sampling methods and interdisciplinary approaches to site investigations are beginning to significantly improve understanding of hydrogeological and microbiological interactions. Likewise, culture-based and molecular analyses of microbial populations in subsurface contaminant plumes have revealed significant adaptation of microbial populations to plume environmental conditions. Results of recent studies suggest that variability in subsurface geochemical and hydrological conditions significantly influences subsurface microbial-community structure. Combined investigations of site conditions and microbial-community structure provide the knowledge needed to understand interactions between subsurface microbial populations, plume geochemistry, and contaminant biodegradation. La biodégradation efficace des polluants souterrains requiert deux éléments: des populations microbiennes possédant les aptitudes nécessaires à la dégradation, et des conditions géochimiques et hydrologiques souterraines favorables. Des contraintes pratiques sur la conception et l'interprétation des expériences à la fois en microbiologie et en hydrogéologie ont conduit à une connaissance limitée des interactions entre les phénomènes hydrogéologiques et microbiologiques des environnements souterrains. Ces contraintes pratiques sont dues à des contradictions entre les échelles d'étude de l'hydrogéologie et de la microbiologie et à des limitations pratiques sur la capacitéà définir avec précision les populations microbiennes dans les échantillons. Cependant, des progrès dans l'application de méthodes d'échantillonnage à l'échelle locale et des approches pluridisciplinaires des études de terrain ont commencéà améliorer de façon significative notre compréhension des interactions hydrogéologiques et microbiologiques. De plus, les analyses moléculaires et sur les cultures des populations microbiennes présentes dans les panaches de pollution souterraine ont mis en évidence une adaptation significative de ces populations aux conditions environnementales du panache. Les résultats d'études récentes laissent penser que la variabilité des conditions géochimiques et hydrologiques souterraines influence significativement la structure des communautés microbiennes souterraines. Des recherches combinées sur les conditions de terrain et sur la structure des communautés microbiennes apportent les informations nécessaires à la compréhension des interactions entre les populations microbiennes souterraines, la géochimie du panache et la biodégradation du polluant. Para que la biodegradación de los contaminantes en el subsuelo sea eficiente se requiere: (1) una población microbiana con capacidad de degradación y (2) unas condiciones hidrológicas y geoquímicas favorables. Las restricciones de tipo práctico en los diseños y la interpretación de experimentos, tanto hidrogeológicos como microbiológicos, han dado lugar a un conocimiento limitado de la interrelación entre estas dos ciencias por lo que respecta al subsuelo. Estas restricciones incluyen: (1) inconsistencias entre las escalas de investigación en ambas ciencias (hidrogeología y microbiología) y (2) limitaciones prácticas para definir poblaciones microbianas en las muestras. Sin embargo, los avances en la aplicación de métodos de muestreo a pequeña escala y las investigaciones de campo con equipos interdisciplinares están mejorando significativamente el conocimiento de las interacciones entre hidrogeología y microbiología. Del mismo modo, los análisis moleculares y de cultivos sobre poblaciones microbianas en penachos contaminados han mostrado la adaptación de los microbios a las condiciones naturales. Estudios recientes sugieren que la variabilidad en las condiciones geoquímicas e hidrogeológicas del subsuelo afecta enormemente la estructura de la comunidad microbiana. Las investigaciones que combinan las condiciones del medio con la estructura de la comunidad microbiana proporcionarán el conocimiento necesario para entender las complejas relaciones entre las poblaciones microbianas subsuperficiales, la geoquímica de los penachos de contaminación y la biodegradación de los contaminantes.

  5. Novel isoguanine derivative of unlocked nucleic acid-Investigations of thermodynamics and biological potential of modified thrombin binding aptamer.

    Thrombin binding aptamer (TBA), is a short DNA 15-mer that forms G-quadruplex structure and possesses anticoagulant properties. Some chemical modifications, including unlocked nucleic acids (UNA), 2'-deoxy-isoguanosine and 2'-deoxy-4-thiouridine were previously found to enhance the biological activity of TBA. In this paper, we present thermodynamic and biological characteristics of TBA variants that have been modified with novel isoguanine derivative of UNA as well as isoguanosine. Additionally, UNA-4-thiouracil and 4-thiouridine were also introduced simultaneously with isoguanine derivatives. Thermodynamic analysis indicates that the presence of isoguanosine in UNA or RNA series significantly decreases the stability of G-quadruplex structure. The highest destabilization is observed for substitution at one of the G-tetrad position. Addition of 4-thiouridine in UNA or RNA series usually decreases the unfavorable energetic cost of the presence of UNA or RNA isoguanine. Circular dichroism and thermal denaturation spectra in connection with thrombin time assay indicate that the introduction of UNA-isoguanine or isoguanosine into TBA negatively affects G-quadruplex folding and TBA anticoagulant properties. These findings demonstrate that the highly-ordered structure of TBA is essential for inhibition of thrombin activity.

    Optimum natural resource management and biodiversity conservation are desirable goals. These, however, often exclude each other, since maximum economic benefits have promoted drastic reductions in biodiversity throughout the world. This dilemma confronts local stakeholders, who usually go for maximizing economic inputs, whereas other social (e.g., academic) sectors are favor conservation practices. In this paper we describe the way two scientific approaches--landscape and participatory research--were used to develop sound and durable land use scenarios. These two approaches included expert knowledge of both social and environmental conditions in indigenous communities. Our major emphasis was given to detect spatially explicit land use scenarios and capacity building in order to construct a decision support system operated by stakeholders of the Comunidad Indigena de Nuevo San Juan Parangaricutiro in Mexico. The system for decision-making was fed with data from inventories of both abiotic and biotic biodiversity components. All research, implementation, and monitoring activities were conducted in close collaboration with members of the indigenous community. As a major result we obtained a number of forest alternative uses that favor emerging markets and make this indigenous community less dependent on a single market. Furthermore, skilled members of the community are now running the automated system for decision-making. In conclusion, our results were better expressed as products with direct benefits in local livelihoods rather than pure academic outputs.

    Environmental radioactivity monitoring includes the determination of radionuclides in foods since they are an important way of intake of radionuclides to the human organism. Moreover, knowledge of the levels of radionuclides in foodstuffs will inform about the environmental radioactivity background permitting to control possible contamination due to human activity, such as agriculture activity, nuclear power plants or other radioactive facilities. The Environmental Radioactivity Laboratory (LRA) at the Universitat Politècnica de València (UPV) performs measurements on representative foods from all over the Comunidad Valenciana (CV). Those measurements are part of several monitoring programs promoted by the Generalitat Valenciana. A total of 2200 samples of fruits, cereals, vegetables, milk, meat, eggs and fish coming from markets, agricultural cooperatives or small producers have been analyzed. A gamma-ray spectrometry analysis has been performed in all samples. It has been detected 40K in all samples, 7Be in some of them. Radiochemical separation of 90Sr has been carried out in some of the samples collected, mainly orange and lettuce. Samples of lettuce and chard collected following Fukushima Nuclear Power Plant (NPP) accident present activity concentration of 131I (0.10-1.51 Bq kg-1). In this paper, a review of the data obtained at the 1991-2013 period in the framework of the development of the Environmental monitoring program is presented.

  13. Emotional and behavioural reactions to moral transgressions: cross-cultural and individual variations in India and Britain.

    Reactions to moral transgressions are subject to influence at both the cultural and individual levels. Transgressions against an individual's rights or against social conventions of hierarchy may elicit different reactions in individualistic and collectivistic cultures. In the current study, affective and behavioural reactions to transgressions of autonomy (rights) and community (hierarchy) were examined in India and Britain. Results revealed that although reactions to autonomy transgressions are similar in India and Britain, Indian participants express more moral outrage than do Britons in response to transgressions of community. Results also supported the contention of emotion-specificity in affective moral reaction: Participants in both India and Britain reported anger in response to autonomy transgressions, but contempt in response to violations of community. Importantly, these results extend previous research by demonstrating the importance of emotion specificity in moral reactions, as opposed to categorization or dilemma resolution. In addition, an individual difference measure of respect for persons was shown to moderate reactions to moral transgressions. Specifically, participants with high respect for persons were less negative to violators of the community ethic, but not the autonomy ethic. These findings highlight the importance of examining emotion-specific responses in the moral domain and introduce a significant individual difference variable, respect for persons, into the psychology of morality. Les réactions aux transgressions morales sont susceptibles d'influence à la fois aux niveaux culturel et individuel. Les transgressions contre les droits d'un individu ou contre les conventions sociales d'hiérarchie peuvent susciter de différentes réactions dans les cultures individualiste et collectiviste. Dans la présente étude, les réactions affective et comportementale aux transgressions de l'autonomie (droits) et de la communauté (hiérachie) ont été examinées en Inde et en Grande-Bretagne. Les résultats ont indiqué que, malgré la similitude des réactions aux transgressions de l'autonomie en Inde et en Grande-Bretagne, les participants indiens ont exprimé plus d'indignation morale que les britanniques en réponse aux transgressions de la communauté. Les résultats ont également appuyé la controverse de la spécifité de l'émotion dans la relation morale affective: les participants à la fois en Inde et en Grande-Bretagne ont rapporté de la colère en réponse aux transgressions de l'autonomie mais du mépris en réponse aux transgressions de la communauté. De façon importante, ces résultats ont élargi la recherche passée en démontrant l'importance de la spécificité de l'émotion dans les réactions morales, contrairement à la catégorisation ou à la solution du dilemme. En plus, il a été démontré qu'une mesure des différences individuelles du respect envers les personnes a modéré les réactions aux transgressions morales. Spécifiquement, les participants ayant un grand respect envers les personnes ont été moins négatifs envers les violateurs de l'éthique de la communauté mais pas de l'éthique de l'autonomie. Ces résultats soulignent l'importance d'examiner les réponses spécifique à l'émotion dans le domaine moral et introduisent une variable des différences individuelles, soit le respect envers les personnes, dans la psychologie de la moralité. Las reacciones a las transgresiones morales están sujetas a la influencia a niveles culturales e individuales. Las transgresiones contra los derechos individuales o convenciones sociales de jerarquías pueden provocar distintas reacciones en las culturas individualistas y colectivistas. En el presente estudio, se examinaron las reacciones afectivas y conductuales a las transgresiones contra la autonomía (derechos) y comunidad (jerarquía) en la India y en Gran Bretaña. Los resultados demostraron que, aunque las reacciones a las transgresiones contra la autonomía fueran parecidas en la India y en Gran Bretaña, los participantes indios expresaron más indignación moral que los británicos en la respuesta a la transgresión contra la comunidad. Los resultados también apoyan la visión de la especificidad emocional en la reacción afectiva moral: los participantes en la India y también en Gran Bretaña mostraron ira en respuesta a la transgresión contra la autonomía y desprecio en respuesta a la violación de la comunidad. De forma importante, estos resultados amplían los estudios anteriores demostrando la importancia de la especificidad emocional en las reacciones morales frente a la categorización o resolución de los dilemas. Adicionalmente, las medidas de las diferencias individuales en el respeto para personas moderan las reacciones a la transgresión moral. Específicamente, los participantes con alto respeto para personas fueron menos negativos a la hora de violar la ética de la comunidad pero no la ética de la autonomía. Estos resultados subrayan la importancia de estudiar las respuestas emocionales específicas en el dominio moral e introducen una variable de diferencias individuales significativas, respeto para personas, dentro de la psicología de la moralidad.

    An Inertial-Electrostatic Confinement (IEC) device was assembled at the Marshall Space Flight Center (MSFC) Propulsion Research Center (PRC) to study the possibility of using EEC technology for deep space propulsion and power. Inertial-Electrostatic Confinement is capable of containing a nuclear fusion plasma in a series of virtual potential wells. These wells would substantially increase plasma confinement, possibly leading towards a high-gain, breakthrough fusion device. A one-foot in diameter IEC vessel was borrowed from the Fusion Studies Laboratory at the University of Illinois@Urbana-Champaign for the summer. This device was used in initial parameterization studies in order to design a larger, actively cooled device for permanent use at the PRC.

    Three well-known photonuclear sum rules (SR), i.e., the Thomas-Reiche-Kuhn, the bremsstrahlungs and the polarizability SR are calculated for He4 with the realistic nucleon-nucleon potential Argonne V18 and the three-nucleon force Urbana IX. The relation between these sum rules and the corresponding energy weighted integrals of the cross section is discussed. Two additional equivalences for the bremsstrahlungs SR are given, which connect it to the proton-neutron and neutron-neutron distances. Using them, together with our result for the bremsstrahlungs SR, we find a deviation from the tetrahedral symmetry of the spatial configuration of He4. The possibility to access this deviation experimentally is discussed.

    Liang Liu, Colin Zarzycki, Ekbordin Winijkul, Tami C. Bond Department of Civil and Environmental Engineering, University of Illinois at Urbana-Champaign, Urbana, IL, USA Carbon monoxide (CO) plays an important role in atmospheric chemistry by acting as the primary sink of the most important atmospheric oxidizer, hydroxyl radicals (OH), and participating in the cycle of tropospheric ozone. CO can also provide constraints on model prediction of black carbon (BC) and vice versa due to their common sources of incomplete combustion. A well developed historical emission inventory of CO would serve the purpose of various global atmospheric models over the historical record. Only a few attempts have been made to represent the time dependence of CO emissions. In this study, we present the first technology based global historical trend of anthropogenic and biofuel emissions of CO from 1850 to 2000. The essential components of a bottom-up emission inventory are technology divisions, fuel consumptions for each technology, and emission factors for each combination of fuel and technology. Previous research done by Bond et al., [2007] has provided this study with technology breakdowns for different combinations of fuel and usage and the time trends of fuel-use for each specific technology in activities that contribute to BC emissions. This work reconstructs the fuel-use trend of the brick and cement industries which were not included in the historical BC emission inventory but play an important role in CO emission. Emission factors are developed for past and present CO emitters. Fuel consumption and emission factors are then combined to estimate global CO emissions at the country level. Uncertainty analysis in activity data, technology splits, and emission factors are performed. The developed historical CO emission trend is compared with the historical BC emission trend to provide more insight into the relationship of the two pollutants.

  10. Use and abuse of the urban groundwater resource: Implications for a new management strategy

    NASA Astrophysics Data System (ADS)

    Drangert, J.-O.; Cronin, A. A.

    Various human activities threaten the groundwater quality and resource under urban areas, and yet residents increasingly depend on it for their livelihood. The anticipated expansion of the world's urban population from 3 to 6 billion in the coming 50 years does not only pose a large water management threat but also provides an opportunity to conserve groundwater in a better way than up to now. The authors argue for a new way to manage urban activities in order to conserve the precious groundwater resource. The focus is on the quality of the discharged water after use in households. Restrictions on what is added to water while using it, e.g. detergents, excreta, paint residues, oils, and pharmaceuticals, are important to simplify the treatment and reuse of used water. Avoiding mixing different wastewater flows has the same positive effect. If increased volumes of wastewater can be treated and reused, the demand on the groundwater resource is reduced, as also occurs with demand management measures. Reduced discharge of polluted water to the environment from households and utilities also conserves the quality of groundwater and reduces sophisticated treatment costs. L'urbanisation conduit à une demande élevée et concentrée d'eau de qualité adéquate, accompagnée du rejet d'importants volumes correspondants d'eaux usées. La nourriture est importée dans les villes tandis que les micro-organismes et les nutriments provenant des excrétas humains sont rejetés dans les rivières, les lacs et aussi les eaux souterraines. De plus, une large gamme de biens de consommation est évacuée par les égouts. Les créances environnementales, c'est-à-dire l'appauvrissement des conditions environnementales qui demandera des apports humains et économiques pour la réhabilitation, sont habituelles dans toutes les villes, et pas seulement dans l'hémisphère sud, comme cela est indiqué dans le rapport sur l'alimentation en eau et la santé publique du monde (publié par l'OMS et UNICEF), établissant que la plupart des eaux résiduaires des zones urbaines reste non traitée (65% en Asie, 86% en Amérique latine et 100% en Afrique). La tâche à réaliser pour l'homme est de protéger les ressources en eau souterraine en sorte qu'elle reste disponible pour les habitants des villes dans le futur. Dans les prochaines 50 années, il faut s'attendre à ce que la population urbaine s'accroisse de 3 à 6 milliards de personnes selon les estimations des Nations Unies; aussi il est impératif de ne pas continuer à polluer les eaux souterraines sous les nouvelles zones urbaines en cours de construction. Dans cet article, nous analyserons la qualité des eaux souterraines et leur protection à la lumière des récents changements de politique de l'eau, c'est-à-dire de la gestion de l'alimentation en eau jusqu'à une gestion de la demande et en abordant éventuellement la période de gestion du recyclage. La urbanización lleva a una demanda elevada y concentrada de agua de calidad adecuada, acompañada por el vertido de volúmenes análogamente mayores de aguas residuales. Los alimentos se importan a ciudades donde los microorganismos y nutrientes de los excrementos humanos son descargados a ríos, lagos y, también, aguas subterráneas. Más aún, gran número de los bienes de consumo son eliminados vía las tuberías de las cloacas. Las deudas medioambientales, es decir, el empobrecimiento de las condiciones medioambientales, que requerirán de aportaciones humanas y económicas para rehabilitarlas, son comunes a todas las ciudades, sobretodo en el Hemisferio Sur, donde, según la Valoración Global de Suministro de Agua y Saneamiento (OMS y UNICEF), la mayor parte de las aguas residuales urbanas no son tratadas (65% en Asia, 86% en Latinoamérica, 100% en África). La tarea pendiente consiste en proteger los recursos de aguas subterráneas para que estén disponibles de forma rápida para los habitantes urbanos también el futuro. En los próximos 50 años, se espera que la población urbana aumente de 3,000 a 6,000 millones de personas, según estimaciones de las Naciones Unidas, por lo que es imperativo dejar de contaminar las aguas subterráneas existentes bajo las nuevas áreas urbanas en construcción. En este artículo, se escudriña la calidad de las aguas subterráneas y su protección a la luz de los cambios recientemente introducidos en las políticas del agua, esto es, desde la gestión de los abastecimientos de agua a la gestión de la demanda y, eventualmente, hastaa la gestión de la reutilitzación.

    A 15-mer DNA aptamer (named TBA) adopts a G-quadruplex structure that strongly inhibits fibrin-clot formation by binding to thrombin. We have performed thermodynamic analysis, binding affinity and biological activity studies of TBA variants modified by unlocked nucleic acid (UNA) monomers. UNA-U placed in position U3, U7 or U12 increases the thermodynamic stability of TBA by 0.15–0.50 kcal/mol. In contrast, modification of any position within the two G-quartet structural elements is unfavorable for quadruplex formation. The intramolecular folding of the quadruplexes is confirmed by Tm versus ln c analysis. Moreover, circular dichroism and thermal difference spectra of the modified TBAs displaying high thermodynamic stability show bands that are characteristic for antiparallel quadruplex formation. Surface plasmon resonance studies of the binding of the UNA-modified TBAs to thrombin show that a UNA monomer is allowed in many positions of the aptamer without significantly changing the thrombin-binding properties. The biological effect of a selection of the modified aptamers was tested by a thrombin time assay and showed that most of the UNA-modified TBAs possess anticoagulant properties, and that the construct with a UNA-U monomer in position 7 is a highly potent inhibitor of fibrin-clot formation.

    Few studies have reported the relationship between sarcopenia and the estimated amount of sodium excreted in 24 h, as measured by the spot urine test (E24UNA), in a community-dwelling cohort. We investigated the gender specific association between E24UNA values and body composition indices. Data from a total of 7162 participants (3545 men and 3617 postmenopausal women) aged 45 years or older were obtained from multiple Korea National Health and Nutrition Examination Surveys (2008-2010) and analyzed. The total amount of sodium excreted in the urine in a 24-h period was estimated with spot urine specimens. Sarcopenia was defined as an appendicular skeletal muscle mass divided by body weight (ASM/Wt) that was less than 1 standard deviation below the sex-specific mean for young adults. E24UNA values were positively correlated with body mass index, waist circumference, total fat mass, and blood pressure; in contrast, E24UNA values were negatively correlated with ASM/Wt in both sexes. Compared with those in the lowest E24UNA tertile, participants in the highest E24UNA tertile were at higher risk for sarcopenia (men: odds ratio (OR)=1.3 [95% confidence interval (CI)=1.07-1.59]; women: OR=1.41 [95% CI=1.16-1.73]). Further classification of subjects with sarcopenia into sarcopenic obese and sarcopenic nonobese groups revealed that the highest E24UNA values were found in the sarcopenic obese group; this difference was statistically significant. The next highest levels were found in the sarcopenic nonobese group, followed by the nonsarcopenic group. This trend was observed in both sexes. High E24UNA values were independently associated with both sarcopenia and obesity in Korean individuals older than 45 years. These results suggest that high salt intake may have a deleterious effect on body composition. Copyright © 2015. Published by Elsevier Inc.

    Little information is available on temporal trends in sodium intake in the U.S. population using urine sodium excretion as a biomarker. Our aim was to assess 1988-2010 trends in estimated 24-h urine sodium (24hUNa) excretion among U.S. adults (age 20-59 y) participating in the cross-sectional NHANES. We used subsamples from a 1988-1994 convenience sample, a 2003-2006 one-third random sample, and a 2010 one-third random sample to comply with resource constraints. We estimated 24hUNa excretion from measured sodium concentrations in spot urine samples by use of calibration equations (for men and women) derived from the International Cooperative Study on Salt, Other Factors, and Blood Pressure study. Estimated 24hUNa excretion increased over the 20-y period [1988-1994, 2003-2006, and 2010; means ± SEMs (n): 3160 ± 38.4 mg/d (1249), 3290 ± 29.4 mg/d (1235), and 3290 ± 44.4 mg/d (525), respectively; P-trend = 0.022]. We observed significantly higher mean estimated 24hUNa excretion in each survey period (P < 0.001) for men compared with women (31-33%) and for persons with a higher body mass index (BMI; 32-35% for obese vs. normal weight) or blood pressure (17-26% for hypertensive vs. normal blood pressure). After adjusting for age, sex, and race-ethnicity, temporal trends in mean estimated 24hUNa excretion remained significant (P-trend = 0.004). We observed no temporal trends in mean estimated 24hUNa excretion among BMI subgroups, nor after adjusting for BMI. Although several limitations apply to this analysis (the use of a convenience sample in 1988-1994 and using estimated 24hUNa excretion as a biomarker of sodium intake), these first NHANES data suggest that mean estimated 24hUNa excretion increased slightly in U.S. adults over the past 2 decades, and this increase may be explained by a shift in the distribution of BMI.

    Information regarding salt intake in pregnant women in Japan is limited. An electronic system for the assessment of salt intake using a 24-h dietary recall method has been developed in Japan. The objectives of the present study were to investigate salt intake in pregnant women and to compare the salt intake estimated by the electronic salt intake assessment system with that measured by 24-h urinary salt excretion (24-hUNaCl). Data were collected on 24-hUNaCl and salt intake estimated by the salt intake assessment system for 35 pregnant Japanese women at approximately 20 weeks of gestation. The adjusted 24-hUNaCl (24-hUNaCl/[the number of urinations during the examination day--the number of missing urine collections] × the number of urinations during the examination day, g/day) was used as a standard. The mean adjusted 24-hUNaCl was 7.7 ± 2.5 g/day, and mean systolic/diastolic blood pressure values were 106.1 ± 8.6/62.8 ± 6.5 mmHg. The adjusted 24-hUNaCl was significantly correlated with the salt intake estimated by the salt intake assessment system (r = 0.47, p = 0.004). Bland-Altman analysis showed no significant mean difference (adjusted 24-hUNaCl--salt intake estimated by the assessment system = -0.36 g/day, p = 0.4) and no significant proportional bias (p = 0.1). These results suggest that pregnant women in Japan restrict their salt intake, at least when they are being examined for salt intake. They also suggest that repeated use of the described system may be useful in estimating salt intake in pregnant women.

    Los astronomos de ESO dedican una considerable parte de su tiempo a la preparacion de solicitudes para tiempo de observacion en La Silla. Sin embargo, debido a la gran demanda par los telescopios, se debe hacer una seleccion, aveces drastica, de los programas de observacion presentados. EI Comite de Programas de Observacion (OPC) tiene como tarea evaluar el merito cientifico de las solicitudes presentadas. Basada en las recomendaciones dei OPC, ESO prepara una Lista de Tiempos de Observacion en la cual distribuye el tiempo disponible en los telescopios a los programas mejor evaluados.

    A method for calibrating data obtained by the Urban sodium lidar system is presented. First, an expression relating the number of photocounts originating from a specific altitude range to the soodium concentration is developed. This relation is then simplified by normalizing the sodium photocounts with photocounts originating from the Rayleigh region of the atmosphere. To evaluate the calibration expression, the laser linewidth must be known. Therefore, a method for measuring the laser linewidth using a Fabry-Perot interferometer is given. The laser linewidth was found to be 6 + or - 2.5 pm. Problems due to photomultiplier tube overloading are discussed. Finally, calibrated data is presented. The sodium column abundance exhibits something close to a sinusoidal variation throughout the year with the winter months showing an enhancement of a factor of 5 to 7 over the summer months.

    To analyze the levels of physical activity and sedentary behavior in adolescents living in urban and rural areas. An epidemiological, cross-section study with quantitative design, carried out at the regional level. The sample comprised 6,234 students aged 14 to 19 years, selected using random cluster sampling. The χ2 test and binary logistic regression were used in the analysis. A total of 74.5% of adolescents lived in urban areas. After adjustment, rural residents spent less time watching television (odds ratio - OR: 0.45; 95% confidence interval - 95%CI: 0.39-0.52), using a computer and/or playing video games (OR: 0.30; 95%CI: 0.22-0.42), or sitting down (OR: 0.66; 95%CI: 0.54-0.80); chose passive leisure less often (OR: 0.83; 95%IC: 0.72-0.95) and were less likely to be classified as insufficiently active (OR: 0.88; 95%IC: 0.78-0.99) when compared to urban residents, regardless of sex or age. The fact that adolescents living in rural areas who did not work were more likely to be classified as insufficiently active (OR: 2.59; 95%CI: 2.07-3.24) emphasized the significant role of occupation in physical activity levels in this group. Adolescents living in rural areas were less exposed to the sedentary behaviors, chose more active leisure, and had higher levels of physical activity. Place of residence and occupation may play a major role in youth lifestyle. Analisar os níveis de atividade física e o comportamento sedentário em adolescentes das áreas urbanas e rurais. Estudo epidemiológico, transversal, com abordagem quantitativa e abrangência estadual, cuja amostra foi constituída por 6.234 estudantes (14 a 19 anos), selecionados por meio de uma estratégia de amostragem aleatória de conglomerados. As análises foram realizadas por meio do teste χ2 e da regressão logística binária. Na amostra, 74,5% dos adolescentes eram residentes em área urbana. Após o ajuste, constatou-se que os adolescentes oriundos da área rural usavam menos televisão (odds ratio - OR: 0,45; intervalo de confiança de 95% - IC95%: 0,39-0,52), computador e/ou videogame (OR: 0,30; IC95%: 0,22-0,42), passavam menos tempo sentados (OR: 0,66; IC95%: 0,54-0,80), optaram menos pelo lazer passivo (OR: 0,83; IC95%: 0,72-0,95) e tinham menos chances de serem classificados como insuficientes ativos (OR: 0,88; IC95%: 0,78-0,99), quando comparados àqueles que residiam na área urbana, independentemente do sexo e da idade. Os adolescentes da área rural que não trabalhavam apresentaram mais chances de serem classificados como insuficientemente ativos (OR: 2,59; IC95%: 2,07-3,24), mostrando que a ocupação tinha um papel importante no nível de atividade física deste grupo. Os adolescentes residentes na área rural estiveram menos expostos aos comportamentos sedentários, optaram mais por um lazer ativo e apresentaram um melhor nível de atividade física, podendo a zona de domicílio e a ocupação influenciar no estilo de vida deles.

  6. Correlation between increased urinary sodium excretion and decreased left ventricular diastolic function in patients with type 2 diabetes mellitus.

    Increased salt intake may induce hypertension, lead to cardiac hypertrophy, and exacerbate heart failure. When elderly patients develop heart failure, diastolic dysfunction is often observed, although the ejection fraction has decreased. Diabetes mellitus (DM) is an established risk factor for heart failure. However, little is known about the relationship between cardiac function and urinary sodium excretion (U-Na) in patients with DM. We measured 24-hour U-Na; cardiac function was evaluated directly during coronary catheterization in type 2 DM (n = 46) or non-DM (n = 55) patients with preserved cardiac systolic function (ejection fraction > or = 60%). Cardiac diastolic and systolic function was evaluated as - dp/dt and + dp/dt, respectively. The average of U-Na was 166.6 +/- 61.2 mEq/24 hour (mean +/- SD). In all patients, stepwise multivariate regression analysis revealed that - dp/dt had a negative correlation with serum B-type natriuretic peptide (BNP; beta = - 0.23, P = .021) and U-Na (beta = - 0.24, P = .013). On the other hand, + dp/dt negatively correlated with BNP (beta = - 0.30, P < .001), but did not relate to U-Na. In the DM-patients, stepwise multivariate regression analysis showed that - dp/dt still had a negative correlation with U-Na (beta = - 0.33, P = .025). The results indicated that increased urinary sodium excretion is associated with an impairment of cardiac diastolic function, especially in patients with DM, suggesting that a reduction of salt intake may improve cardiac diastolic function.

    RESUMEN México vive una transición demográfica en la cual el porcentaje de la población mayor de 50 años de edad crece aceleradamente como resultado de un aumento considerable en la esperanza de vida. Dicha población tiene necesidades particulares que deben ser tomadas en cuenta en la formulación de políticas, sobre todo en materia de acceso a servicios de salud y seguridad social. En este artículo presentamos una descripción general de la Encuesta Nacional de Salud y Envejecimiento (Enasem), un estudio de panel que comenzó en 2001 y que ofrece una oportunidad única para abordar temas demográficos y económicos complejos por medio de la exploración de las características personales, transferencias socioeconómicas e indicadores de salud para una muestra de 15 186 adultos de edad media y avanzada. También presentamos los resultados más relevantes de diferentes estudios que han utilizado la Enasem hasta la fecha. Nuestra revisión indica que México enfrenta desafíos considerables para satisfacer la demanda de servicios médicos para una población que es amenazada por una creciente presencia de enfermedades crónicas, sobre todo para la población de edad avanzada que no cuenta con cobertura de seguro médico.

    En el marco de un proyecto de investigación-acción que se implementó en Venezuela de 2009 a 2013 se buscó empoderar (empower) a activistas sociales y pacientes en la lucha contra el cáncer de mama (CM). Este proyecto se puso en marcha en un contexto de alta polarización política y social en el marco de la llamada «Revolución bolivariana». A partir de una perspectiva ecológica de la comunicación y el activismo en salud, que integra los niveles interpersonal, grupal y social, se celebraron una serie de actividades orientadas a desarrollar las habilidades de vocería de ciudadanos, especialmente de mujeres, y ampliar las redes de cooperación entre diversos sectores, al mismo tiempo que se perfiló una visión consensuada entre actores sociales e institucionales sobre una respuesta nacional contra el CM. Una comunicación horizontal y participativa permitió que se escuchara la voz de actores usualmente marginalizados en las políticas sanitarias. PMID:27867911

    To analyze the care provided to tuberculosis cases in primary health care services according to the elements of the Chronic Care Model. Cross-sectional study conducted in a capital city of the northeastern region of Brazil involving 83 Family Health Strategy professionals.A structured tool adapted to tuberculosis-related care in Brazil was applied.Analysis was based on the development of indicators with capacity to produce care varying between limited and optimum. The organization of care for tuberculosis and supported self-care presented reasonable capacity.In the coordination with the community, the presence of the community agent presented optimum capacity.Partnership with organizations of the community and involvement of experts presented limited capacity.The qualification of professionals, the system for scheduling and monitoring tuberculosis in the community, and the clinical information system presented basic capacity. The capacity of the primary health care services to produce tuberculosis-related care according to the elements of the Chronic Care Model is still limited.Overcoming the fragmentation of care and prioritizing a systemic operation between actions and services of the health care network remains as a major challenge.

  14. Diurnal pattern of sodium excretion in dogs with and without chronically reduced renal perfusion pressure.

    1996-01-01

    In 5 conscious dogs the diurnal patterns of urinary sodium excretion (UNaV) were investigated, initially during 1 control day and, thereafter, during 4 days of servo-controlled reduction of renal perfusion pressure (rRPP). The individual dog's mean arterial blood pressure was reduced to 80% of the blood pressure on the control day. This value was always found to be below the threshold for the pressure-dependent renin release. During the entire study period urine was collected in 4-hour intervals and blood samples were taken every 4 h. The dogs were kept on a standardized high sodium and high water intake and were fed once daily at 8.30 h. On the control day, UNaV, urinary flow rate (UV), fractional lithium excretion (FELi) and fractional sodium excretion (FENa) had similar diurnal patterns. They peaked 4-8 h after food intake and decreased to low values during the night. On day 1 of rRPP, UNaV and FENa were maintained at very low levels in all collection periods, whereas the patterns of UV and FELi were unaltered compared with the patterns on the control day. On days 2-4 of rRPP, a clear-cut maximum in the patterns of UNaV and FENa recurred, comparable with the patterns on the control day. However, compared with the control day this maximum was shifted by 4 h towards the night. In contrast, the patterns of UV and FELi remained unchanged compared with the control day. The results indicate that UNaV has a typical time course in conscious, sodium- and water-replete dogs fed once daily. Endogenous stimulation of sodium reabsorption by means of rRPP results in a characteristic 4-hour shift of UNaV and FENa towards the night during rRPP days 2-4. This delay in UNaV seems to be evoked by processes in the distal tubule.

    Los estudios llevados a cabo en la transición del hidrógeno neutro a λ~21-cm han contribuído a incrementar nuestro conocimiento acerca de las propiedades globales del medio interestelar, sea este galáctico o extragaláctico. Avances en este campo han sido provocados, a menudo, por la puesta en servicio de radiotelescopios que poseen una mayor resolución angular. Aquí se presenta una propuesta para desarrollar un nuevo instrumento, un interferómetro, que permitirá abrir nuevas líneas de investigación. Este instrumento combinará la técnica de síntesis de apertura con la de espectroscopía de correlación digital, para alcanzar una resolución angular de 1' y un campo de visión de ~1o.7.

    ?`Qué es la Astronomía para Ciegos?. El trabajo es una adaptación en base a la escala de magnitudes de Hipparco que cambia el concepto de luz por una adaptación sonora, donde las estrellas de magnitud 6 se escuchan en 10 dB, más o menos lo que consideramos el umbral de la audición humana. Quienes no escuchan muy bien no pueden escuchar las magnitudes 6, de la misma manera que muchos de nosotros, que no poseemos una visión perfecta, no podemos observar esas mismas estrellas en el cielo (más allá de la polución). A los astros de magnitud 5 vamos a relacionarlos a un sonido en 20 dB. Y así sucesivamente. También los colores estarán representados en una convención de graves a agudos y lo mismo algunas características del cielo. Por ejemplo, la Vía Láctea se mostrará como un ``ruido", como bien nos lo hicieron ver nuestros futuros destinatarios. En Mar del Plata nos encontramos ya trabajando en un proyecto que tiene como objetivo final la construcción del Primer Planetario Acústico del Mundo, una herramienta para la enseñanza de la astronomía, un espacio para la lucha contra la discriminación del discapacitado y una posibilidad de ``ver el cielo de un modo diferente".

    Morales Ramos, Egda M.

    La teoria de evolucion biologica (TEB) por seleccion natural es uno de los conceptos unificadores mas importantes del curriculo de Biologia. En Puerto Rico se han hecho pocas investigaciones que abunden sobre las concepciones y concepciones alternativas (CA) que tienen los estudiantes universitarios/as de Biologia y los maestros/as de Ciencia del nivel secundario sobre esta teoria. La politica publica educativa actual establece mediante documentos normativos como los Estandares de contenido y Expectativas de grado del Programa de Ciencias [Puerto Rico Core Standards] la ensenanza de esta teoria. Sin embargo, no se encontraron preguntas sobre la seleccion natural en los ejercicios de practica provistos por el Departamento de Educacion para las pruebas estandarizadas lo cual puede influir para que no se ensene adecuadamente. Las preguntas de investigacion fueron 1. ¿Cuales son las concepciones y concepciones alternativas de estudiantes universitarios/as y de los futuros maestros y maestras de Ciencia sobre la TEB? 2. ¿Cuales conceptos que seleccionan los estudiantes universitarios/as y los futuros maestros y maestras de Ciencia sobre la TEB coinciden con lo aceptado como valido por la comunidad cientifica? y 3. ¿Como comparan las respuestas de la prueba original. v. Entendiendo el cambio biologico que mide concepciones y CA sobre la TEB por seleccion natural, con las de la traducida al idioma espanol? Se utilizo el metodo cuantitativo con un diseno de investigacion transversal por encuesta. La tecnica principal para recopilar los datos fue una prueba con doce items, que formo parte de un instrumento para el cual se recopilaron diversas fuentes de evidencia acerca de su validez. Las muestras estuvieron formadas por 69 estudiantes de Ciencias Naturales y por 16 estudiantes futuros maestros y maestras del nivel secundario de la UPR-RP. Se utilizaron estadisticas descriptivas, analisis de Ji cuadrado y se calcularon los coeficientes alfa de Cronbach y de Spearman. Estos demostraron que la prueba es confiable para medir las concepciones y CA de la TEB por seleccion natural. Aunque los estudiantes escogieron conceptos relacionados con esta teoria, mantienen en sus procesos de razonamiento CA sobre la seleccion natural que no se limitan a la lamarckiana y a la teleologica.

    Community-based physical activity (PA) programs in Latin America have been recognized because of the use of available environmental resources to offer PA classes. Yet, the evaluation of programs focused on PA classes involving dancing in public spaces is limited. The aim of this study was to assess the physical activity levels, park use, and the contextual characteristics of public parks with and without the Recreovía in Bogotá in Colombia. Al Ritmo de las Comunidades is a natural experiment conducted in nine parks (3 parks implementing new Recreovías, 3 control parks and 3 parks with existing Recreovías) during 2013. We used the System for Observing Play and Recreation in Communities to evaluate park use (gender, age, and physical activity level) and target areas. A total of 4925 people were observed during 702 observation visits to parks. The percentage of women was higher in parks with Recreovía, compared to parks without Recreovía (53% vs. 40% vs. 33%; p < 0.001). Women using parks with Recreovía compared to women in parks without Recreovía were less likely to be sedentary (25% vs. 39%; p < 0.0001) and more likely to engage in moderate-to-vigorous activity (75% vs. 61%; p < 0.0001). Among men, the activity pattern was the opposite. The Recreovía is a promising strategy to promote park use and PA, especially among women who are less likely to meet PA recommendations during their leisure time. The provision of a cost-free community program may be an effective approach and a good investment for health. PMID:28608844

    Limited research has documented interventions aimed at promoting use of existing recreational community resources among underserved populations. This study (HEART [Health Education Awareness Research Team] Phase 2) reports findings of an intervention (Mi Corazón Mi Comunidad) where community health workers facilitated use of diet and exercise programming at local recreational facilities among Mexican American border residents. The aim was to evaluate overall attendance rates and to assess which factors predicted higher attendance. The design was a cohort study. From 2009 to 2013, a total of 753 participants were recruited across 5 consecutive cohorts. The intervention consisted of organized physical activity and nutrition programming at parks and recreational facilities and a free YWCA membership. Attendance at all activities was objectively recorded. Regression analyses were used to evaluate whether demographic factors, health status, and health beliefs were associated with attendance. Results Participants included mostly females at high risk for cardiovascular disease (72.4% were overweight/obese and 64% were [pre-]hypertensive). A total of 83.6% of participants attended at least one session. On average, total attendance was 21.6 sessions (range: 19.1-25.2 sessions between the different cohorts), including 16.4 physical activity and 5.2 nutrition sessions. Females (p = .003) and older participants (p < .001) attended more sessions. Participants low in acculturation (vs. high) attended on average seven more sessions (p = .003). Greater self-efficacy (p < .001), perceived benefits (p = .038), and healthy intentions (p = .024) were associated with higher attendance. Conclusions The intervention was successful in promoting use of recreational facilities among border residents at high risk for cardiovascular disease. Findings were similar across five different cohorts. © 2015 Society for Public Health Education.

    A comunidade astronômica brasileira de há muito almeja ter a sua disposição um instrumento científico com o qual possa fazer pesquisa de vanguarda e manter a competitividade científica a nível internacional. Hoje este sonho se torna uma realidade. O Brasil tem tido uma política de pesquisa e de pós-graduação bem sucedida. Estamos formando 7000 doutores por ano e produzimos 1,5% da ciência mundial. Nosso desafio, hoje, é associar a esta capacidade de gerar conhecimento também a capacidade de usar o conhecimento em beneficio da sociedade. A Astronomia não é exceção. Temos 7 programas de pós-graduação em nível de doutorado e 11 em nível de mestrado. O telescópio SOAR será o principal instrumento que sustentará estes programas nas próximas décadas. A inauguração do telescópio SOAR simboliza de forma concreta e decidida o apoio do MCT, do CNPq e da FAPESP para o financiamento à pesquisa básica em nosso país. O Laboratório Nacional de Astrofísica, criado a cerca de 20 anos pelo CNPq, a par do Laboratório Nacional de Luz Sincrotron, são até hoje, os únicos laboratórios nacionais do Brasil e ambos voltados basicamente ao avanço do conhecimento. Os vinte anos de existência do LNA foram decisivos para a estruturação da comunidade astronômica no Brasil e para a construção das parcerias como o SOAR.

    Background The traditional knowledge of local communities throughout the world is a valuable source of novel ideas and information to science. In this study, the ethnoveterinary knowledge of Sahrawi pastoralists of Western Sahara has been used in order to put forward a scientific hypothesis regarding the competitive interactions between camels and caterpillars in the Sahara ecosystem. Methods Between 2005 and 2009, 44 semi-structured interviews were conducted with Sahrawi pastoralists in the territories administered by the Sahrawi Arab Democratic Republic, Western Sahara, using a snow-ball sampling design. Results Sahrawi pastoralists reported the existence of a caterpillar-borne reproductive loss syndrome, known locally as duda, affecting their camels. On the basis of Sahrawi knowledge about duda and of a thorough literature review, we built the hypothesis that: 1) caterpillars of the family Lasiocampidae (genera Lasiocampa, Psilogaster, or Streblote) have sudden and rare outbreaks on Acacia treetops in the Western Sahara ecosystem after heavy rainfall; 2) during these outbreaks, camels ingest the caterpillars while browsing; 3) as a consequence of this ingestion, pregnant camels have sudden abortions or give birth to weaklings. This hypothesis was supported by inductive reasoning built on circumstantiated evidence and analogical reasoning with similar syndromes reported in mares in the United States and Australia. Conclusions The possible existence of a caterpillar-borne reproductive loss syndrome among camels has been reported for the first time, suggesting that such syndromes might be more widespread than what is currently known. Further research is warranted to validate the reported hypothesis. Finally, the importance of studying folk livestock diseases is reinforced in light of its usefulness in revealing as yet unknown biological phenomena that would deserve further investigation. Resumen ‘Todos lo saben’, menos el resto del mundo: el caso de un síndrome de pérdida reproductiva en dromedarios transmitido por orugas y observado por pastores nómadas saharauis del Sáhara Occidental. Antecedentes Los conocimientos tradicionales de las comunidades locales de todo el mundo son una valiosa fuente de nuevas ideas e información para la ciencia. En este estudio, se utilizaron los conocimientos de etnoveterinaria de pastores saharauis del Sáhara Occidental con el fin de proponer una hipótesis científica sobre las interacciones competitivas entre los camellos y las orugas en el ecosistema del Sáhara. Métodos Entre los años 2005 y 2009, se realizaron 44 entrevistas semi-estructuradas a los pastores saharauis en los territorios administrados por la República Árabe Saharaui Democrática, Sáhara Occidental, mediante un diseño de muestreo por bola de nieve. Resultados Los pastores nómadas saharauis describieron un síndrome reproductivo transmitido por orugas, llamado duda, entre sus camellas. Sobre la base de los conocimientos saharauis sobre el duda y una revisión literaria exhaustiva, se propuso la siguiente hipótesis: 1) brotes esporádico de orugas de la familia Lasiocampidae (géneros Lasiocampa, Psilogaster o Streblote) en árboles de Acacia se pueden presentar después de fuertes lluvias en el ecosistema del Sáhara Occidental; 2) durante estos brotes, los camellos ingieren las orugas durante el pastoreo; 3) como consecuencia de esta ingestión, se producen abortos repentinos o partos de crías debilitadas. Apoyamos esta hipótesis mediante razonamiento inductivo basado en evidencia circunstancial y razonamiento analógico con síndromes similares en yeguas de los Estados Unidos y Australia. Conclusiones Este es el primer reporte de la posible existencia de un síndrome de pérdida reproductiva en camellos, transmitido por orugas. Se insinúa que estos síndromes son más comunes que lo que actualmente se conoce. Se sugieren investigaciones adicionales para poner a prueba nuestra hipótesis. Finalmente, se destaca la importancia de estudios de las enfermedades del ganado en pueblos de pastores nómadas porque pueden revelar fenómenos biológicos aún desconocidos y merecen ser investigados.

    For more than 15 years lidar systems have been used to study the chemistry and dynamics of the mesospheric sodium layer. Because the layer is an excellent tracer of atmospheric wave motions, sodium lidar has proven to be particularly useful for studying the influence of gravity waves and tides on mesospheric dynamics. These waves, which originate in the troposphere and stratosphere, propagate through the mesosphere and dissipate their energy near the mesopause making important contributions to the momentum and turbulence budget in this region of the atmosphere. Recently, the sodium lidar was modified for daytime operation so that wave phenomena and chemical effects could be monitored throughout the complete diurnal cycle. The results of continuous 24 hour lidar observations of the sodium layer structure are presented alond with measurement of the semidiurnal tidal winds.

  5. Clinical decision support tools in A&E nursing: a preliminary study.

    PubMed

    New, T D

    This article describes how a large trust in the north east of England is in the process of developing a unique service for non-emergency patients in one of its main A&E departments. The Urgent Need Assessment Service (UNAS), co-located within the main A&E department, features the use of NHS Direct computerised algorithms to enable nurses to recommend the best treatment or course of action accurately and safely, for all patients attending the department who are categorised as blue or green status in accordance with the Manchester triage model of A&E assessment. The UNAS facility incorporates discretely staffed minor injuries and minor ailments services. UNAS assessment nurses are specially trained to use their A&E experience, together with the computer model, and to make an assessment in partnership with the patient, sharing information displayed on the computer screen and working together to reach a jointly agreed treatment plan or outcome. The UNAS pilot and evaluation commenced in September 1999 and results and outcomes are presented for the period from September 3 to December 31 2000. Approximately 75 per cent of all A&E attenders are given blue or green status. UNAS has led to faster treatment and reduced waiting times for these people, increasing patient satisfaction while enabling the A&E department to concentrate its resources on treating more serious cases. This pilot study has proved to be highly satisfactory to the majority of people who have been treated at UNAS. Those previously regarded as 'inappropriate attenders' might be better suited to treatment in a different department, separate from the traditional A&E department, with reduced waiting times, and under the care of specially trained nurses.

    Introducción: el aumento de la motivación hacia la Educación Física podría resultar un elemento esencial para propiciar un incremento en la condición física saludable de los escolares. La ausencia de estudios en población española hace necesario el desarrollo de esta línea de investigación.Objetivos: el objetivo del presente estudio fue examinar la asociación entre la motivación hacia la Educación Física y los niveles de condición física saludable en adolescentes de Educación Secundaria Obligatoria.Métodos: un total de 294 escolares (167 varones y 127 mujeres), de 13 a 16 años de edad cumplimentaron la versión española de la Escala de Locus Percibido de Causalidad en Educación Física y realizaron las pruebas de condición física saludable de la Batería ALPHA-Fitness de Alta Prioridad.Resultados: los resultados del estudio mostraron una asociación positiva entre tener una alta motivación hacia la Educación Física y presentar una mayor capacidad cardiorrespiratoria, tanto en niños como en niñas (p < 0,05). En cambio, no se encontró una asociación entre la motivación hacia la Educación Física y el sobrepeso o fuerza muscular.Conclusiones: existe una asociación positiva entre la motivación hacia la Educación Física y la capacidad cardiorrespiratoria. Por tanto, con el objetivo de que los alumnos presenten una capacidad cardiorespiratoria saludable, los profesores de Educación Física deberían promover la motivación hacia la Educación Física.

  7. La formación de la Nube de Oort y el entorno galáctico primitivo

    NASA Astrophysics Data System (ADS)

    Fernández, J. A.

    Se analizan las condiciones de formación de la nube de Oort en el medio galáctico primitivo, bajo la suposición de que los objetos que alcanzaron la nube fueron planetesimales residuales eyectados por los planetas gigantes durante las etapas finales de su acreción. Los objetos que adquieren órbitas cuasiparabólicas están sujetos a las perturbaciones de estrellas vecinas y al potencial del disco galáctico, las que desacoplan sus perihelios de la región planetaria, dando a los objetos una larga estabilidad dinámica. Se demuestra que un entorno galáctico como el presente pudo, sin embargo, no ser suficiente para formar un reservorio cometario con una vida dinámica comparable a la vida del sistema solar. La existencia de la nube de Oort después de 4600 millones de años es, pues, una fuerte indicación de que el sistema solar se formó en un entorno galáctico mucho mas denso que el presente, tal vez en una nube molecular y/o un cúmulo abierto, que es el modo de producción de la mayoría de las estrellas. Se encuentra que un campo perturbador externo mas intenso, producto de un entorno galáctico mas denso, sería capaz de formar una nube de Oort mas compacta, con un radio del orden de 103- 104 UA. El campo externo mas intenso cesó de actuar una vez que la nube molecular y/o el cúmulo abierto se disiparon, previniendo entonces que ese mismo campo externo disolviera el reservorio cometario.

    Carpintero, D. D.

    Durante los últimos años, ha ido adquiriendo importancia la descripción dinámica de un sistema estelar a través de su estructura orbital, complementando el tradicional uso de la función de distribución en el espacio fase. El desarrollo de esta nueva concepción condujo, con el tiempo, a la conclusión de que las órbitas caóticas juegan un importante papel dinámico en modelos realistas de galaxias. Sin embargo, la determinación de la caoticidad de una órbita, o de la familia regular a la cual pertenece, siguió siendo una tarea artesanal. Nuevos métodos de clasificación fueron surgiendo con el tiempo; hoy en día, se cuenta con métodos que permiten determinar automáticamente el contenido orbital de cualquier potencial arbitrario que se desee para modelar una galaxia, o incluso determinar la familia de una órbita sin siquiera conocer el potencial en el que está sumergida.

    Introducción: El neumoencéfalo a tensión luego de la cirugía transesfenoidal es poco común. En la literatura existen pocos casos reportados en los cuales el aire se encuentra localizado exclusivamente en las regiones selar y supraselar, constituyendo un pneumatocele selar. En este artículo se describe un caso inusual de pneumatocele selar a tensión de presentación tardía. Descripción del caso: Una mujer de 57 años consultó por hemianopsia bitemporal. Previamente, ya se le había realizado una cirugía transnasal por un adenoma hipofisario y se le había colocado una derivación lumbo-peritoneal por la presencia de una fístula de líquido cefalorraquídeo. Además, se le había realizado una resección transcraneal de un componente intracavernoso del tumor y radiocirugía debido a la agresividad del mismo. Se llevó a cabo una resonancia magnética que demostró un pneumatocele selar y supraselar. Intervención: Se realizó un abordaje transciliar. La región selar estaba encapsulada por tejido cicatrizal debido a los procedimientos previos. Se abrió la cicatriz y el aire fue evacuado. Posteriormente, el piso selar fue cerrado con grasa y cola de fibrina. Despuós del procedimiento, su campo visual retornó a la normalidad. Un año después de su última cirugía, continua asintomática. Conclusión: El pneumatocele selar y supraselar a tensión es un hallazgo extremadamente raro luego de una cirugía transesfenoidal. Su manifestaciónw clínica sería la alteración visual debida a la compresión inferior de la vía óptica. El pneumatocele selar a tensión debe ser evacuado en un corto plazo. PMID:23596554

    Resumen Introducción: La patología de la unión cráneo-cervical es poco frecuente en la práctica neuroquirúrgica diaria. En general la mayor parte de estas lesiones son de origen traumático o reumatológico. La inestabilidad atlanto-axial de origen inflamatorio (Síndrome de Grisel) es una rara entidad de la que solo se han reportado 16 casos adultos en la literatura. Esta patología se caracteriza por el desarrollo de una lesión osteolítica a nivel de la articulación atlanto-axoidea posterior a un evento infeccioso, generalmente de las vías aéreas superiores. Descripción del caso: Presentamos el caso de una paciente de 76 años quien concurre en consulta por un cuadro clínico de inestabilidad cráneo espinal secundaria a una lesión osteolítica, con compromiso de C1 y C2. La sintomatología comenzó posteriormente a un proceso infeccioso respiratorio. Se realizó una fijación occípito-cervical posterior y una Odontoidectomía con descompresión anterior por vía endoscópica transnasal. La paciente evolucionó con resolución completa de los síntomas. Los cultivos fueron negativos y el estudio de anatomía patológica concluyó cambios inflamatorios inespecíficos. Conclusión: Hasta hace algunos pocos años la única opción para abordar esta patología era la vía transoral con técnica microquirúrgica. Hoy en día la endoscopía nos brinda muchas ventajas técnicas por lo que constituye una opción a tener en cuenta en la planificación de los abordajes a la unión cráneo-cervical. PMID:29430326

  13. Linear Magnetochiral effect in Weyl Semimetals

    NASA Astrophysics Data System (ADS)

    Cortijo, Alberto

    We describe the presence of a linear magnetochiral effect in time reversal breaking Weyl semimetals. The magnetochiral effect consists in a simultaneous linear dependence of the magnetotransport coefficients with the magnetic field and a momentum vector. This simultaneous dependence is allowed by the Onsager reciprocity relations, being the separation vector between the Weyl nodes the vector that plays such role. This linear magnetochiral effect constitutes a new transport effect associated to the topological structures linked to time reversal breaking Weyl semimetals.

    Introducción y objetivos: la evolución que ha experimentado en los últimos años la sociedad española ha originado una serie de cambios sociológicos y/o culturales que afectan claramente a los hábitos y preferencias alimentarias. El objetivo del presente trabajo ha sido evaluar la adherencia a la dieta mediterránea (DM) de la población universitaria en la ciudad de Murcia y la calidad de su desayuno, estableciendo la relación existente entre estas dos variables entre sí, y otras variables sociológicas analizadas.Métodos: se evaluó la adherencia a la DM en una muestra de 312 estudiantes mediante el test KIDMED, cuestionario de 16 preguntas. La calidad del desayuno fue determinada en función de la ingesta de los distintos grupos de alimentos (lácteos, cereales y frutas), de forma que se establecieron las siguientes categorías de calidad: pésima, mala, regular y buena. De cada encuestado se registraron los datos personales, lugar de origen, zona geográfica y tipo de residencia, sexo, edad, titulación universitaria, curso y las variables antropométricas (peso, altura, perímetro de cintura y cadera).Resultados: la muestra estuvo formada por 238 mujeres y 74 hombres todos ellos estudiantes universitarios de distintos títulos de grado. El 7,85% de los universitarios mostró una baja adherencia a la DM, el 48,4% media y el 43,8% alta. Los estudiantes de grado en Educación Primaria mostraron una mayor adherencia media a la DM; los estudiantes de grado en Enfermería tomaron más de una ración de verdura al día; y los de Ciencia y Tecnología de los Alimentos consumían una pieza de fruta al día. Teniendo en cuenta el sexo de los participantes, el 37,8% de las mujeres tomaban más de una verdura diaria y el 91,5% desayunaba bollería industrial; mientras que el 54,1% de los hombres tomaban frutos secos (al menos 2 o 3 veces por semana) y el 74,5% desayunaba todos los días. El 1,15% de los estudiantes mostró una calidad del desayuno pésima, el 17,65% mala, el 60,65% regular y el 20,45% buena, coincidiendo la buena calidad con el consumo de fruta en esta comida. Además, se observó una asociación significativa entre el tiempo y la calidad del desayuno, ya que aquellos estudiantes que dedicaban más de diez minutos a desayunar tomaban un desayuno de buena calidad.Conclusión: en este estudio se ha visto que la calidad del desayuno está estrechamente relacionada con el grado de adherencia al patrón dietético mediterráneo.

  16. Chronobiology of the renin-angiotensin-aldosterone system in dogs: relation to blood pressure and renal physiology.

    The renin-angiotensin-aldosterone system (RAAS) plays a pivotal role in the regulation of blood pressure and volume homeostasis. Its contribution to the development of cardiovascular diseases has long been recognized. Extensive literature has shown that peptides of the RAAS oscillate with a circadian periodicity in humans, under strong influence of posture, sleep, and age. Although observations of time-variant changes in the renin cascade are available in dogs, no detailed chronobiological investigation has been conducted so far. The present studies were designed to explore the circadian variations of plasma renin activity (RA) and urinary aldosterone-to-creatinine ratio (UA:C) in relation to blood pressure (BP), sodium (UNa, UNa,fe), and potassium (UK, UK,fe) renal handling. Data derived from intensive blood and urine sampling, as well as continuous BP monitoring, were collected throughout a 24-h time period, and analyzed by means of nonlinear mixed-effects models. Differences between the geometric means of day and night observations were compared by parametric statistics. Our results show that variables of the renin cascade, BP, and urinary electrolytes oscillate with significant day-night differences in dogs. An approximately 2-fold (1.6-3.2-fold) change between the average day and night measurements was found for RA (p < 0.001), UA:C (p = 0.01), UK,fe (p = 0.01), and UNa (p = 0.007). Circadian variations in BP, albeit small (less than 10 mm Hg), were statistically significant (p < 0.01) and supported by the model-based analysis. For all variables but UNa and UNa,fe, the levels were higher at night than during the day. The data also indicate that blood pressure oscillates in parallel to the RAAS, such that, as opposed to healthy humans, BP does not drop at night in dogs. The postprandial decrease in RA is assumed to be related to body fluid volume expansion secondary to water and sodium intake, whereas the reduction of UA:C reflects aldosterone-stimulated secretion by the renin-angiotensin II pathway. UNa and UNa,fe peaked in the afternoon, about 7-8 h after food intake, which is consistent with the "impulse-response pattern" of sodium excretion described in previous publications. Finally, UK and UK,fe mirrored aldosterone-mediated potassium secretion in the kidney tubules. To describe the circadian variations of the various variables, two different mathematical representations were applied. A cosine model with a fixed 24-h period was found to fit the periodic variations of RA, UA:C, UK, UK,fe, and BP well, whereas changes in UNa and UNa,fe were best characterized by a surge model. The use of nonlinear mixed effects allowed estimation of population characteristics that can influence the periodicity of the RAAS. Specifically, sodium intake was found to interact with the tonic and the phasic secretion of renin, suggesting that varying feeding time could also impact the chronobiology of the renin cascade.

    RIASSUNTO. Il disturbo da uso di alcol (DUA) è uno dei disturbi psichiatrici più comuni nella popolazione generale. Il DUA è caratterizzato da un pattern di bere eccessivo, che si mantiene nonostante gli effetti negativi che l'alcol ha sul funzionamento lavorativo, sulla salute, sulle problematiche legali, sull'educazione e sulla vita sociale. Attualmente, il modello bio-psico-sociale è quello che spiega meglio il DUA. Infatti, molte ricerche hanno fornito evidenze su come il DUA sia una patologia multidimensionale. Variabili biologiche, psicologiche e socio-culturali entrano in gioco nell'eziologia, nella natura, nel mantenimento e nel cambiamento nel tempo del disturbo. La fase diagnostica è un momento importante del processo di cura, perché il successo del trattamento dipende in larga misura dall'esattezza e dall'adeguatezza della diagnosi. La diagnosi clinica si basa su una valutazione globale del funzionamento del paziente e utilizza il colloquio e gli strumenti psicometrici come mezzo di raccolta di informazioni. Questo articolo fornirà una panoramica delle dimensioni psicologiche più importanti da valutare e sui migliori strumenti psicometrici da usare per una diagnosi adeguata.

    Argonne National Laboratory leads the Joint Center for Energy Storage Research (JCESR), a major collaborative research partnership with the goal of developing next-generation energy storage technologies. JCESR supplements its traditional project management approach with scientific “Sprints.” The Sprint described in this video involved a multidisciplinary team from Argonne, the University of Illinois at Urbana-Champaign, Massachusetts Institute of Technology, and the University of Michigan. As they studied how polymers in solution can react electrochemically to store energy, the team solved a crucial battery problem: “crossover,” which is caused by molecules mixing together when they should not, resulting in reduced performance. Manymore » possible materials were tested, and a set of candidate polymers were chosen that are stable, cheap to make, and suitable for conditions required in batteries.

    1998-01-01

    In support of the NASA Lewis Modern Airfoils Ice Accretion Test Program, the University of Illinois at Urbana-Champaign provided expertise in airfoil design and aerodynamic analysis to determine the aerodynamic effect of ice accretion on modern airfoil sections. The effort has concentrated on establishing a design/testing methodology for "hybrid airfoils" or "sub-scale airfoils," that is, airfoils having a full-scale leading edge together with a specially designed and foreshortened aft section. The basic approach of using a full-scale leading edge with a foreshortened aft section was considered to a limited extent over 40 years ago. However, it was believed that the range of application of the method had not been fully exploited. Thus a systematic study was being undertaken to investigate and explore the range of application of the method so as to determine its overall potential.

  7. Lidar observations of wave-like structure in the atmospheric sodium layer

    The University of Illinois (Urbana) lidar system has been developed to study the atmospheric sodium layer near 90 km altitude through the mechanism of resonance scattering. The photocount data are processed using digital smoothing filters to obtain continuous estimates of the sodium density versus altitude. The filter cutoff frequency is related to the height resolution and accuracy of the estimated profile. Lidar photocount data processed using this filtering technique show wave-like structures in the sodium layer which move downward with time. The waves have typical wavelengths of 3-15 km and phase velocities of less than 1 m/sec. The movement of these structures seems to be independent of the motion of the bottomside of the layer, which also has been observed to move up or down by as much as 2 km over a period of a few hours.

    Plasma disruptions pose a major threat to the operation of tokamaks which confine a large amount of stored energy. In order to effectively mitigate this damage it is necessary to predict an oncoming disruption with sufficient warning time to take mitigative action. Machine learning approaches to this problem have shown promise but require further developments to address (1) the need for machine-portable predictors and (2) the availability of multi-dimensional signal inputs. Here we demonstrate progress in these two areas by applying the Disruption Predictor Feature Developer to data from JET and NSTX, and discuss topics of focus for ongoing work in support of ITER. The author is also supported under the Fulbright U.S. Student Program as a graduate student in the department of Nuclear, Plasma and Radiological Engineering at the University of Illinois at Urbana-Champaign.

    2017-10-01

    Advancements were made in the development of the kinetic-kinetic electrostatic Particle-in-Cell code, hPIC, designed for large-scale simulation of the Plasma-Material Interface. hPIC achieved a weak scaling efficiency of 87% using the Algebraic Multigrid Solver BoomerAMG from the PETSc library on more than 64,000 cores of the Blue Waters supercomputer at the University of Illinois at Urbana-Champaign. The code successfully simulates two-stream instability and a volume of plasma over several square centimeters of surface extending out to the presheath in kinetic-kinetic mode. Results from a parametric study of the plasma sheath in strongly magnetized conditions will be presented, as well as a detailed analysis of the plasma sheath structure at grazing magnetic angles. The distribution function and its moments will be reported for plasma species in the simulation domain and at the material surface for plasma sheath simulations. Membership Pending.

    Argonne National Laboratory leads the Joint Center for Energy Storage Research (JCESR), a major collaborative research partnership with the goal of developing next-generation energy storage technologies. JCESR supplements its traditional project management approach with scientific “Sprints.” The Sprint described in this video involved a multidisciplinary team from Argonne, the University of Illinois at Urbana-Champaign, Massachusetts Institute of Technology, and the University of Michigan. As they studied how polymers in solution can react electrochemically to store energy, the team solved a crucial battery problem: “crossover,” which is caused by molecules mixing together when they should not, resulting in reduced performance. Many possible materials were tested, and a set of candidate polymers were chosen that are stable, cheap to make, and suitable for conditions required in batteries. The collaboration allowed timely development that would have taken much longer had the groups been working independently.

    2003-01-01

    In Illinois, atmospheric deposition is one major source of heavy metal inputs to agricultural land. The atmospheric Pb deposition and transport record in agricultural soils in Champaign, Illinois, was established by studying surface and subsurface soil samples collected during the past 100 years from the Morrow Plots on the campus of the University of Illinois at Urbana-Champaign. The Pb content in the soil samples was measured and the Ph deposition fluxes were calculated. The Pb content in surface soils increased sharply in the first half of the 20th century, and stayed invariant since. The maximum Pb flux from the atmosphere was estimated to be 27 (??14) ??g cm-2 yr-1 around 1940. The major pollution source for this increase probably was residential coal burning. It was estimated that in 50 yr, more than 50% of the Pb input had been lost from the surface soils.

  14. Using multimedia learning modules in a hybrid-online course in electricity and magnetism

    2011-06-01

    We have been piloting web-based multimedia learning modules (MLMs), developed by the Physics Education Research Group at the University of Illinois at Urbana Champaign (UIUC), as a “prelecture assignment” in several introductory physics courses at California State Polytechnic University at Pomona. In this study, we report the results from a controlled study utilizing modules on electricity and magnetism as a part of a blended hybrid-online course. We asked students in the experimental section to view the MLMs prior to attending the face-to-face class, and to make sure this would not result in additional instructional time, we reduced the weekly class time by one-third. We found that despite reduced class time, student-learning outcomes were not hindered; in fact, the implementation of the UIUC MLMs resulted in a positive effect on student performance on conceptual tests and classroom discussion questions.

  15. Research productivity in select psychology journals, 1986-2008.

    Examination of research productivity has a long history in psychology. Journals across psychology have periodically published research-productivity studies. An analysis of institutional research productivity was conducted for 17 journals published by the American Psychological Association for the years 1986-2008. This analysis implemented two methodologies: one a replication and extension of G. S. Howard, D. A. Cole, and S. E. Maxwell's (1987) method, the other a new method designed to give credit to psychology departments rather than only overall institutions. A system of proportional credit assured all articles with multiple institutions received credit. Results show that for the 23-year period, the University of Illinois at Urbana-Champaign was ranked 1st, followed by the University of California, Los Angeles, and the University of Michigan, Ann Arbor. Overall, results showed both consistency and change across all journals examined. The authors explore the implications of these findings in the context of the current academic environment.

  16. Fotometría UBVI en NGC 6231

    NASA Astrophysics Data System (ADS)

    Baume, G. L.; Vázquez, R. A.; Feinstein, A.

    Se ha realizado fotometría CCD UBVI en la zona del cúmulo abierto NGC 6231, habiéndose observado 1062 estrellas hasta una magnitud V≈ 19. Esto posibilita tener una imagen clara de la parte inferior de la secuencia principal del cúmulo. Combinando nuestros datos con tipos espectrales tomados de la literatura pudimos re-derivar la ley de absorción en dirección a este cúmulo y encontrar que los valores de R muestran variaciones de estrella a estrella. La secuencia principal inferior muestra también algunos rasgos intrigantes: hay un codo notorio en V≈ 13.5 seguido por un gran ``spread'' de magnitudes a color constante entre las estrellas débiles y una inusualmente alta densidad de estrellas a lo largo de una banda que se extiende 1.5 mag encima de la ZAMS. Los cálculos indican que el número esperado de estrellas de campo en dirección al cúmulo debería ser menor que el observado. Una re-evaluación de las funciones de luminosidad y masa dentro de los límites -7.5 < MV < 1.5 mag y 2 Msolar < M arroja pendientes planas para ambas funciones, lo que parece ser típico de cúmulos muy jóvenes. Todos estos rasgos son congruentes con un escenario joven donde las estrellas en fase de contracción están arribando a la secuencia principal.

    Objetivos. Examiné los efectos combinados del acceso a la atención primaria mediante el Programa de Salud Familiar (PSF) y las transferencias condicionadas de dinero en efectivo del Programa Bolsa Familia (PBF) sobre la mortalidad infantil posneonatal (MIPN) en Brasil. Métodos. Empleé un análisis ecológico longitudinal usando datos en panel de 4 583 municipios brasileños de 1998 al 2010, con 54 253 observaciones en total. Estimé modelos de regresión de efectos fijos por mínimos cuadrados ordinarios, con la tasa de MIPN como la variable dependiente y el PSF, el PBF y sus interacciones como las principales variables independientes de interés. Resultados. La asociación de una mayor cobertura del PSF con una menor tasa de MIPN se volvió más fuerte conforme aumentaba la cobertura del PBF. En los promedios de todas las demás variables, cuando la cobertura de PBF era 25%, la MIPN predicha fue 5,24 (intervalo de confianza [IC] de 95% = 4,95, 5,53) para una cobertura del PSF de 0%, y de 3,54 (IC de 95% = 2,77, 4,31) para una cobertura del PSF de 100%. Cuando la cobertura del PBF era de 60%, la MIPN predicha fue 4,65 (IC de 95% = 4,36, 4,94) para una cobertura del PSF de 0%, y de 1,38 (IC de 95% = 0,88, 1,89) para una cobertura del PSF de 100%. Conclusiones. El efecto del PSF depende de la ampliación del PBF. Para las poblaciones empobrecidas y subatendidas, la combinación de intervenciones tanto del lado de la oferta como del lado de la demanda podría ser necesaria para mejorar los resultados en salud.

  18. Puerto Rico, humedales [Puerto Rico, wetlands

    1999-01-01

    La isla de Puerto Rico, localizada al noreste del Mar Caribe y sus islas principales, Vieques, Culebra e Isla de Mona, poseen humedales en abundancia . El clima subtropical, la lluvia abundante y las complejas formas topográficas y geológicas de estas islas dan origen a los humedales, que varían desde los raros e inusuales bosques cubiertos por nubes en las tierras altas, hasta los extensos manglares, yerbas marinas y arrecifes de coral a lo largo de las costas Norte y Sur. Sin embargo, los humedales en Puerto Rico han disminuido en los últimos siglos como resultado del aumento en el desarrollo agrícola, poblacional y turístico. Algunos tipos de humedales como los bosques de palo de pollo (Pterocarpus officinalis) se han reducido a sólo unos pocos remanentes (figura 1).Biológicamente hablando, los humedales de las islas están entre las áreas más productivas. Los humedales asociados con el bosque pluvial en las tierras altas del interior de Puerto Rico contienen varias plantas raras y especies de animales que no se encuentran en otras partes de la Isla. El agua de escorrentía proveniente de los humedales en las partes altas de la Isla proveen una fuente de agua que utilizan varias ciudades para abasto público. Los humedales costeros como los mangles, los colchones de yerbas marinas y los arrecifes de coral proveen áreas para la reproducción y crianza de varios peces, crustáceos y otras especies en la cadena alimenticia (López y otros, 1988). De esta manera, los humedales costeros contribuyen a la productividad biológica de las aguas llanas del mar alrededor de las islas . Los humedales también estabilizan las costas atrapando y reteniendo sedimentos no consolidados y amortiguan la acción de las olas y de las tormentas que tienen el potencial de causar daños en la zona.El valor de los humedales de Puerto Rico para la vida silvestre está muy bien documentado . Por ejemplo, las salinas de Cabo Rojo, en la costa suroeste, proveen áreas para el descanso y la alimentación de cientos de aves migratorias en ruta entre Norte y Suramérica. Antes del drenaje de los humedales costeros para propósitos agrícolas, pantanos de agua dulce como los de la Laguna Cartagena, Laguna Guánica y Ciénaga El Anegado proveían hábitat a más de 1 00 especies de aves residentes y migratorias . Los humedales de las tierras altas del área central son el último refugio de la cotorra puertorriqueña, una especie en peligro de extinción. Aún los humedales del área metropolitana de San Juan (Laguna La Torrecilla, Torrecilla Baja, Laguna de Piñones hasta Punta Vacía Talega) proveen un hábitat excelente para la vida silvestre, mantienen criaderos de peces de alto valor económico y proveen recreación y oportunidades educativas a la población urbana.Treintiocho especies de vertebrados, moluscos y crustáceos, y 46 especies de aves, algunos raros o en peligro de extinción como la mariquita, el alcatraz, el pato dominicano, el pato silbón y la paloma cabeciblanca han sido observados en el área . También las playas asociadas con estos humedales urbanos proveen sitios de anidaje para las tortugas carey de concha y tinglar, ambas en peligro de extinción (Del Llano y otros, 1986).

    La simulación numérica de supernovas tipo II muestra que los mecanismos físicos convencionales no son suficientes como para producir la explosión. La detonación de materia nuclear en materia extraña es un mecanismo físico capaz de proveer la energía faltante en las simulaciones. En esta comunicación se muestra que la turbulencia en el corazón compacto de una supernova, después del primer choque, es capaz de transformar una combustión lenta en una detonación. Se concluye que, si la materia extraña existe, todas las ``estrellas de neutrones'' son, en realidad, ``estrellas extrañas''.

  4. Radio Synthesis Imaging - A High Performance Computing and Communications Project

    NASA Astrophysics Data System (ADS)

    Crutcher, Richard M.

    The National Science Foundation has funded a five-year High Performance Computing and Communications project at the National Center for Supercomputing Applications (NCSA) for the direct implementation of several of the computing recommendations of the Astronomy and Astrophysics Survey Committee (the "Bahcall report"). This paper is a summary of the project goals and a progress report. The project will implement a prototype of the next generation of astronomical telescope systems - remotely located telescopes connected by high-speed networks to very high performance, scalable architecture computers and on-line data archives, which are accessed by astronomers over Gbit/sec networks. Specifically, a data link has been installed between the BIMA millimeter-wave synthesis array at Hat Creek, California and NCSA at Urbana, Illinois for real-time transmission of data to NCSA. Data are automatically archived, and may be browsed and retrieved by astronomers using the NCSA Mosaic software. In addition, an on-line digital library of processed images will be established. BIMA data will be processed on a very high performance distributed computing system, with I/O, user interface, and most of the software system running on the NCSA Convex C3880 supercomputer or Silicon Graphics Onyx workstations connected by HiPPI to the high performance, massively parallel Thinking Machines Corporation CM-5. The very computationally intensive algorithms for calibration and imaging of radio synthesis array observations will be optimized for the CM-5 and new algorithms which utilize the massively parallel architecture will be developed. Code running simultaneously on the distributed computers will communicate using the Data Transport Mechanism developed by NCSA. The project will also use the BLANCA Gbit/s testbed network between Urbana and Madison, Wisconsin to connect an Onyx workstation in the University of Wisconsin Astronomy Department to the NCSA CM-5, for development of long-distance distributed computing. Finally, the project is developing 2D and 3D visualization software as part of the international AIPS++ project. This research and development project is being carried out by a team of experts in radio astronomy, algorithm development for massively parallel architectures, high-speed networking, database management, and Thinking Machines Corporation personnel. The development of this complete software, distributed computing, and data archive and library solution to the radio astronomy computing problem will advance our expertise in high performance computing and communications technology and the application of these techniques to astronomical data processing.

    Objetivo: el objetivo de este estudio es evaluar las propiedades psicométricas del cuestionario de disfrute por el ejercicio físico (PACES) en adolescentes con sobrepeso y obesidad.Métodos: participaron 139 adolescentes con sobrepeso y obesidad: 91 niñas (edad = 13,85 ± 1,92 años; índice de masa corporal [IMC] = 26,83 ± 3,16 kg/m2) y 48 niños (edad = 14,29 ± 1,62 años; IMC = 28,31 ± 3,74 kg/m2). Para analizar el disfrute por la actividad física se empleó el cuestionario Physical Activity Enjoyment Scale (PACES).Resultados: los resultados del análisis factorial exploratorio y confirmatorio han mostrado una estructura de dos factores; a su vez el PACES presenta una consistencia interna muy alta (alfa de Cronbach = 0,908). La fiabilidad test-retest indica una buena concordancia temporal (Spearman rho = 0,815, p < 0,001). Por último, el PACES en adolescentes con sobrepeso y obesidad manifiesta una validez convergente adecuada con la intencionalidad de ser activo (MIFA), la atracción por la actividad física (CAPA), la resistencia cardiorrespiratoria y los pliegues suprailiacoy subescapular.Conclusión: los resultados confirman que el PACES es una medida válida y fiable del disfrute por la actividad física en adolescentes con sobrepeso y obesidad. El disfrute por la actividad física puede ser relevante en la participación de los adolescentes con sobrepeso y obesidad en estas actividades.

    Valotto, C. A.; Muriel, H.; Moore, B.; García Lambas, D.

    En este trabajo se discute sobre la presencia de un exceso de galaxias de baja luminosidad en medios de alta densidad de galaxias y la posibilidad de que los halos de galaxias cD puedan ser formados a partir de galaxias en cúmulos ricos, los cuales muestran una función de luminosidad (FL) con el extremo débil plano. Se analizaron muestras de cúmulos cercanos obtenidas a partir de los catálogos de Abell y X-ray Sample of Bright Clusters. Los resultados obtenidos muestran que los cúmulos de galaxias que tienen emisión en rayos X detectada poseen una FL plana (α ≈ -1.2), consistente con los valores encontrados para las galaxias de campo. En cambio, los cúmulos de galaxias identificados a partir de distribuciones bidimensionales de galaxias que no tienen su contraparte en rayos X, muestran una FL con una pendiente pronunciada en el extremo débil (α ≈ -1.6). Se examinaron además, los posibles efectos debido a la presencia de una galaxia central dominante sobre el extremo débil de la FL. Se analizaron muestras de acuerdo a la clasificación Bautz-Morgan dividiendo en las submuestras I,I-II y II, II- III, III. Las FL resultantes para ambas muestras son indistinguibles. Nuestros resultados son consistentes con la hipótesis de que los efectos de proyección en cúmulos identificados en dos dimensiones pueden producir un exceso artificial de galaxias de baja luminosidad.

    Community resources (parks, recreational facilities) provide opportunities for health promotion, but little is known about how to promote utilization of these resources and their impact on cardiovascular disease risk (CVD). This cohort study evaluated the impact of an intervention called Mi Corazon Mi Comunidad (MiCMiC), which consisted of promoting use of community physical activity and nutrition resources by Promotoras de Salud/Community Health Workers. Participants were assessed at baseline and following the 4-month intervention. Attendance records were objectively collected to assess utilization of intervention programing. A total of five consecutive cohorts were recruited between 2009 and 2013. Participants were mostly females (86.0%), on average 46.6 years old, and 81% were low in acculturation. Participants who completed follow-up (n = 413) showed significant improvements in reported health behaviors and body composition. Higher attendance significantly predicted greater improvements. The baseline to 4-month change for the highest vs. the lowest attendance quartiles were for weight (-5.2 vs. +0.01 lbs, p < 0.001), waist circumference (-1.20 vs. -0.56 inches, p = 0.047), hip circumference (-1.13 vs. -0.41 inches, p < 0.001); hours of exercise/week (+3.87 vs. +0.81 hours, p < 0.001), proportion of participants eating five servings of fruits and vegetables/day (+54.7 vs. 14.7%, p < 0.001). Following the Promotora-led MiCMiC intervention, substantial improvements in health behaviors and modest improvements in cardiovascular risk factors were found. Greater utilization of community resources was associated with more favorable changes. This study provided preliminary evidence for the effectiveness of Promotora-led interventions for promoting use of existing community resources in CVD risk reduction.

    Legionella pneumophila infects humans to produce legionellosis and Pontiac fever only from environmental sources. In order to establish control measures and study the sources of outbreaks it is essential to know extent and distribution of strain variants of this bacterium in the environment. Sporadic and outbreak-related cases of legionellosis have been historically frequent in the Comunidad Valenciana region (CV, Spain), with a high prevalence in its Southeastern-most part (BV). Environmental investigations for the detection of Legionella pneumophila are performed in this area routinely. We present a population genetics study of 87 L. pneumophila strains isolated in 13 different localities of the BV area irrigated from the same watershed and compare them to a dataset of 46 strains isolated in different points of the whole CV. Our goal was to compare environmental genetic variation at two different geographic scales, at county and regional levels. Genetic diversity, recombination and population structure were analyzed with Sequence-Based Typing data and three intergenic regions. The results obtained reveal a low, but detectable, level of genetic differentiation between both datasets, mainly, but not only, attributed to the occurrence of unusual variants of the neuA locus present in the BV populations. This differentiation is still detectable when the 10 loci considered are analyzed independently, despite the relatively high incidence of the most common genetic variant in this species, sequence type 1 (ST-1). However, when the genetic data are considered without their associated geographic information, four major groups could be inferred at the genetic level which did not show any correlation with sampling locations. The overall results indicate that the population structure of these environmental samples results from the joint action of a global, widespread ST-1 along with genetic differentiation at shorter geographic distances, which in this case are related to the common watershed for the BV localities.

The results obtained reveal a low, but detectable, level of genetic differentiation between both datasets, mainly, but not only, attributed to the occurrence of unusual variants of the neuA locus present in the BV populations. This differentiation is still detectable when the 10 loci considered are analyzed independently, despite the relatively high incidence of the most common genetic variant in this species, sequence type 1 (ST-1). However, when the genetic data are considered without their associated geographic information, four major groups could be inferred at the genetic level which did not show any correlation with sampling locations. The overall results indicate that the population structure of these environmental samples results from the joint action of a global, widespread ST-1 along with genetic differentiation at shorter geographic distances, which in this case are related to the common watershed for the BV localities.

    RESUMEN. Para poder explicar: 1) la enorme cantidad de perdida de masa y la baja velocidad asint5tica de las estrellas gigantes de o, y 2) los flujos de masa observados en protoestrellas, se sugiere un modelo para Ia perdida de masa, en donde se usa un flujo de ondas de Alfvencomo un mecanismo de aceleraci6n para los vientos de estrellas de tipo y vientos en protoestrellas. Se estudian los mecanismos de disipaci5n de las ondas de Alfven: los amortiguamientos no lineal, de superficie reso- nante y turbulento. En nuestro modelo se usa una divergente A(r) = A(R0) (r/r0)5 (donde A(r) es el area a una distancia radial r, y (A(r)/r2)max/(A(ro)/r02 - 10). Tambien se sugiere un modelo para una de hoyo coronal en el Sol. Se muestra que para satisfacer los datos observacionales en el Sol, tomando en cuenta la deposici6n del momento de las ondas de Alfven sobre el viento, se necesita: (a) una divergencia lenta en un hoyo coronal hasta una altura de 0.01 - 0.1 R seguido de (b) una divergencia rap ida de hasta una altura aproximada de 1 R . ABSTRACT: In order to explain (1) a large mass-loss rate and a small asymptotic flow speed of late-type giant stars and (2) the observed protostellar mass outflows, we suggest a model for mass loss, where we use a flux of Alfven waves as a mechanism of acceleration for late-type giant star winds and protostellar winds. We study the Alfven wave dissipation mechanisms: nonlinear damping, resonant surface damping, and turbulent damping. In our model we use a diverging geometry A(r) = A(r0) (r I r )S (where A(r) is the cross sectional area of the geometry at a radial distance r, and(A(r) I r2)max/(A(r0)/r02) = 10). We also suggest a model for a coronal hole geometry in the sun. We show that in order to satisfy the observational data of the sun, taking into account Alfven wave momentum deposition in the wind, we need: (a) a slow divergence in a coronal hole up t6 a height of 0.01 - 0.1 followed by (b) a rapid divergence up to a height of approximately 1 Re Key : '? #TICS - STARS-LATE TYPE - STARS- LOSS

  20. Identification of Suitable Water Harvesting Zones Based on Geomorphic Resources for Drought Areas: A Case Study of Una District, Himachal Pradesh, India.

    Prakasam, D. C., Jr.; Zaman, B.

    2014-12-01

    Water is one of the most vital natural resource and its availability and quality determine ecosystem productivity, both for agricultural and natural systems. Una district is one of the major potential agricultural districts in Himachal Pradesh, India. More than 70% of the population of this district is engaged in agriculture and allied sectors and major crops grown are maize, wheat, rice, sugarcane, pulses and vegetables. The region faces drought every year and about 90 per cent of the area is water stressed. This has resulted in crop loss and shortage of food and fodder. The sources of drinking water, small ponds and bowlies dry-up during summer season resulting in scarcity of drinking water. Una district receives rainfall during monsoons from June to September and also during non-monsoon period (winter). The annual average rainfall in the area is about 1040 mm with 55 average rainy days. But due to heavy surface run-off the farmers not able to cultivate the crops more than once in a year. Past research indicate that the geomorphology of the Una district might be responsible for such droughts as it controls the surface as well as ground water resources. The research proposes to develop a water stress model for Una district using the geomorphic parameters, water resource and land use land cover data of the study area. Using Survey of India topographical maps (1:50000), the geomorphic parameters are extracted. The spatial layers of these parameters i.e. drainage density, slope, relative relief, ruggedness index, surface water body's frequency are created in GIS. A time series of normalized remotely sensed data of the study area is used for land use land cover classification and analyses. Based on the results from the water stress model, the drought/water stress areas and water harvesting zones are identified and documented. The results of this research will help the general population in resolving the drinking water problem to a certain extent and also the cultivators to water the crops more than twice per year which might increase the crop yield in Una district.

  1. Development cooperation in water and sanitation: is it based on the human rights framework?

    2017-07-01

    The water and sanitation sector is verifiably receiving increased attention and funding through international development cooperation. Not least because of the way that it affects incentives and institutions in partner countries, development cooperation can have either positive or negative effects on human rights though. The consolidated frameworks for the human rights to water and sanitation is becoming linked to the international community's coordinated development efforts, as evidenced notably in the 2030 Agenda for Sustainable Development. However, a review of major funders' official policies for development cooperation in the sector suggests that many only partially endorse the frameworks for the human rights to water and sanitation. An observation of development cooperation flows to the sector allows the hypothesis to be advanced that worldwide inequalities in access to these services may be reduced through a full and clear application of the human rights framework in development cooperation activities. The article presents findings of this research and explores key stakes for development cooperation in the water and sanitation sector that are relevant for their ability to either negatively or positively contribute to the realization of human rights. Resumen El sector de agua y saneamiento ha recibido creciente atención y financiación a través de la cooperación internacional para el desarrollo. La cooperación para el desarrollo puede tener efectos tanto positivos cuanto negativos sobre los derechos humanos. El hito que consolida los derechos humanos al agua y al saneamiento están articulados a esfuerzos de cooperación para el desarrollo promovidos por la comunidad internacional, como se evidencia en la Agenda 2030 para el Desarrollo Sostenible. Sin embargo, una revisión de las políticas oficiales de los principales financiadores del sector sugiere que muchos de ellos aprueban solo parcialmente los hitos de los derechos humanos al agua y el saneamiento. La observación de los flujos de esta cooperación para el sector permite formular la hipótesis de que las desigualdades en el acceso a estos servicios en diferentes partes del mundo pueden reducirse con la aplicación completa y clara del marco de los derechos humanos en las actividades de cooperación para el desarrollo. El artículo presenta los resultados de esta investigación y explora los desafíos de la cooperación para el desarrollo del sector de agua y aguas residuales que son relevantes para impactar tanto negativamente cuanto positivamente a los derechos humanos.

    Introducción: la hipercolesterolemia es uno de los principales factores de riesgo en la enfermedad cardiovascular. Los esteroles vegetales se han postulado como agentes reguladores y beneficiosos para el control de esta.Objetivo: analizar el efecto de los esteroles vegetales añadidos en una leche en la reducción del colesterol plasmático en adultos jóvenes.Métodos: ensayo clínico, controlado, aleatorizado, doble ciego y cruzado. Los esteroles (2,24 g diarios) fueron administrados en dos tomas de 350 ml de una leche comercial desnatada, durante dos periodos de 3 semanas, separados por una "fase de lavado" de 2 semanas, en el grupo experimental. Al grupo control se le administró la misma cantidad de leche desnatada, sin esteroles. Tanto al inicio como al final de cadaperiodo de intervención se extrajeron muestras sanguíneas. Se analizaron la composición corporal, hábitos de salud y los siguientes marcadores sanguíneos: perfil lipídico, hematológico, inflamación, etc.Resultados: se incluyeron 54 personas en el estudio con una edad media de 38,8 ± 7,3 años. La diferencia porcentual entre los marcadores basales y finales para el colesterol total, colesterol-LDL, colesterol-HDL, triglicéridos y colesterol no-HDL fueron del 9,73%, 12,5%, 1,9%, 3,15% y 13,2%, respectivamente. Se obtuvieron diferencias estadísticamente significativas entre el grupo experimental y el grupo control, para todos los marcadores analizados excepto para los triglicéridos.Conclusión: los esteroles vegetales suministrados en un alimento de consumo habitual, como la leche, pueden ser una estrategia terapéutica no farmacológica para el control de la hipercolesterolemia de alto interés sanitario.

  3. Meningococco B: controllo di due focolai epidemici mediante vaccinazione

    2014-01-01

    Riassunto La problematica di un efficace approccio vaccinale nei confronti del Meningococco B (MenB) è stata superata identificando con la metodica della "reverse vaccinology" alcuni antigeni capaci di indurre una risposta verso la maggior parte dei ceppi di MenB circolanti nel mondo. Il nuovo vaccino MenB a 4 componenti (4CMenB) è stato autorizzato in Europa, Australia e Canada, ed è entrato nei calendari di immunizzazione pediatrica internazionali: Australia, Canada, UK. In Italia, le prime regioni che hanno raccomandato la vaccinazione contro il MenB sono state Basilicata e Puglia. La gestione di epidemie/focolai epidemici richiede la messa in atto di una risposta rapida da parte delle autorità sanitarie nei confronti di una emergenza sanitaria ad elevato impatto, anche emotivo, sulla popolazione, come recentemente dimostrato in due università americane. Alla dichiarazione di focolaio epidemico in atto, in entrambi i contesti si è attivata una procedura per l'uso del vaccino 4CMenB non ancora autorizzato negli USA. È stato così possibile organizzare gli interventi di profilassi attiva nei due campus universitari, adottando il primo impiego su larga scala del nuovo vaccino 4CMenB e conseguendo, in tempi relativamente brevi, elevati tassi di copertura vaccinale. A fronte di circa 14000 studenti immunizzati con almeno una dose, non è stata segnalata alcuna problematica di eventi avversi conseguenti all'immunizzazione; ad oggi non si sono verificati casi nei soggetti che hanno ricevuto il vaccino. Come conseguenza dei due focolai descritti, è oggi in corso la valutazione da parte dell'FDA per l'estensione dell'uso del vaccino 4CMenB negli Stati Uniti negli adolescenti e giovani adulti.

    Introducción: la obesidad es una enfermedad asociada a diferentes trastornos físicos y emocionales que inciden en la calidad de vida y que representan un problema de elevada prevalencia en el mundo. La etiología es múltiple y compleja; se ha señalado la culpa como consecuencia del sobrepeso y, al mismo tiempo, como factor asociado al aumento de peso. En México no existen instrumentos para evaluar la culpa por obesidad y sobrepeso en niños y adolescentes. Objetivos: analizar la fiabilidad y validez de la Escala de Culpa por Obesidad o Sobrepeso para Niños y Adolescentes (ECOSNA) en población de Morelia (México). Material y métodos: se elaboró una versión preliminar basada en la bibliografía que se sometió a la revisión de jueces expertos. La escala obtenida de 6 ítems se aplicó a una muestra de 1.418 estudiantes de educación básica de 7 a 15 años. Se realizó un análisis factorial confir- matorio y se estudió la relación de la escala con otras variables como autoestima, sintomatología depresiva y ansiedad. Resultados: la escala resultó unifactorial, se obtuvo un índice alfa de Cronbach de 0,853. La escala ECOSNA mostró una correlación moderada e inversa con la escala de autoestima, y directa y baja con la sintomatología depresiva y la ansiedad clínica. Conclusión: los datos empíricos indican que la escala presenta una validez y confiabilidad satisfactorias.

    Introducción: los meningiomas del foramen óptico producen un rápido deterioro de la función visual aún cuando su tamaño es pequeño, por eso su diagnóstico y manejo difiere del resto de los meningiomas clinoideos. El propósito de este estudio es presentar la técnica y los resultados de nuestro manejo quirúrgico de meningiomas foraminales (MF). Pacientes y Métodos: se llevó a cabo una revisión de las historias clínicas de 47 pacientes con meningiomas primarios intraorbitarios. Se realizaron 52 cirugías en los pacientes con MF. Se empleó una craneotomía fronto-orbitaria, seguida de una descompresión extradural del canal óptico, resección del componente intraorbitario y exploración intradural del nervio óptico. Resultados: de los 12 pacientes con MF que presentaban la visión conservada, la agudeza visual fue preservada en 7 casos, mejoró en 2, y empeoró en 3. En 18 pacientes, el principal síntoma fue exoftalmos y en 35 pacientes ceguera unilateral. Ocurrieron 6 recurrencias, 2 a 10 años después de la resección quirúrgica. Cinco de ellos fueron reoperados. Se indicó radioterapia después de la recurrencia en 3 pacientes. Conclusión: el manejo de los MF continúa siendo controvertido y frecuentemente se propone un tratamiento conservador. Basados en nuestros hallazgos de frecuente extensión intracraneal, proponemos realizar una resección total o subtotal del tumor, preservando el nervio óptico en pacientes con visión prequirúrgica conservada.

  6. Unilateral adrenalectomy improves urinary protein excretion but does not abolish its relationship to sodium excretion in patients with aldosterone-producing adenoma.

    Experimental and human data suggest that adverse cardiovascular (CV) and renal effects of aldosterone excess are dependent on concomitant dietary salt intake. Increased urinary protein (Uprot) is an early sign of nephropathy independently associated with CV risk. We have previously reported a positive association between Uprot and urinary sodium (UNa) in patients with hyperaldosteronism, but not in patients with normal aldosterone levels. We aimed to determine whether Uprot is related to UNa in patients with aldosterone-producing adenoma (APA) and whether the degree of Uprot and strength of this relationship is reduced following correction of hyperaldosteronism. Subjects with APA (n=24) underwent measurement of 24 h Uprot and UNa before and after unilateral adrenalectomy (follow-up 15.0±11.9 months). Following surgery, mean clinic systolic blood pressure fell (150.4±18.2 vs 134.5±14.5 mm Hg, P=0.0008), despite a reduction in number of antihypertensive medications, and Uprot (211.2±101.6 vs 106.0±41.8 mg per day, P<0.0001) decreased. There was a positive correlation between Uprot and UNa both before (r=0.5477, P=0.0056) and after (r=0.5097, P=0.0109) adrenalectomy. Changes in UNa independently predicted Uprot reduction (P=0.0189). These findings suggest that both aldosterone levels and dietary salt contribute to renal damage, and that once glomerular damage occurs it is not completely resolved following correction of hyperaldosteronism. Our study suggests that treatment strategies based on reduction of aldosterone effects, by adrenalectomy or mineralocorticoid receptor blockade, in conjunction with low-salt diet would provide additional target-organ protection in patients with primary aldosteronism.

    Analizando los datos combinados de los relevamientos de HI de Hartmann & Burton (1997) y Arnal et.al (2000), hemos detectado la presencia de una estructura en forma de ``shell" en la denominada ``ventana de Puppis". Esta estructura, cuyo centro se encuentra en la dirección (l = 245 deg, b = -5 deg) tiene un diámetro angular de ˜ 18 deg y es detectada en el rango de velocidades (LSR) entre -9 y +6 km/seg. El análisis de los datos sugiere que esta estructura puede haberse originado en una perturbación en el denominado ``Feature A" de Lindblad (1973), a una distancia de 150-200 pc del Sol. Se determinaron parámetros tales como Masa y Energía Cinética del Shell y se analiza un posible origen del mismo.

    La confiabilidad es entendida como una propiedad métrica de las puntuaciones de un instrumento de medida. Recientemente se viene utilizando el coeficiente omega (ω) para la estimación de la confiabilidad. No obstante, la medición nunca es exacta por la influencia del error aleatorio, por esa razón es necesario calcular y reportar el intervalo de confianza (IC) que permite encontrar en valor verdadero en un rango de medida. En ese contexto, el artículo plantea una forma de estimar el IC mediante el método de bootstrap para facilitar este procedimiento se brindan códigos de R (un software de acceso libre) para que puedan realizarse los cálculos de una forma amigable. Se espera que el artículo sirva de ayuda a los investigadores de ámbito de salud.

    2017-01-01

    The absorption, distribution, metabolism and excretion (ADME) of metabolites and toxic organic solutes are orchestrated by the ATP-binding cassette (ABC) transporters and the organic solute carrier family (SLC) proteins. A large number of ABC and SLC transpoters exist; however, only a small number have been well characterized. To facilitate the analysis of these transporters, which is important for drug safety and physiological studies, we developed a sensitive genetically encoded bilirubin (BR)-inducible fluorescence sensor (eUnaG) to detect transporter-coupled influx/efflux of organic compounds. This sensor can be used in live cells to measure transporter activity, as excretion of BR depends on ABC and SLC transporters. Applying eUnaG in functional RNAi screens, we characterize l(2)03659 as a Drosophila multidrug resistant-associated ABC transporter. PMID:28176814

    Activated carbons (ACs) have been prepared using chestnut, cedar and walnut wood shavings from furniture industries located in the Comunidad Autónoma de Extremadura (SW Spain). Phosphoric acid (H3PO4) at different concentrations (i.e. 36 and 85 wt.%) has been used as activating agent. ACs have been characterized from the results obtained by N2 adsorption at 77 K. Moreover, the fractal dimension (D) has been calculated in order to determine the AC surface roughness degree. Optimal textural properties of ACs have been obtained by chemical activation with H3PO4 36 wt.%. This is corroborated by the slightly lower values of D for samples treated with H3PO4 85 wt.%.

    Hace 80 años, la Escuela de Medicina de la Universidad Nacional, en voz de su director, Gustavo Baz Prada, hizo una propuesta que pronto se convirtió en realidad y finalmente en norma, la que desde entonces se conoce como SS. Esta iniciativa se vio como una manera para que los estudiantes de medicina del último año retribuyeran a la sociedad una parte de lo que esta invirtió en su educación, consolidaran su formación mediante la exposición a las realidades de todos los días en los medios más necesitados, se pusieran a prueba sobre sus verdaderas capacidades para atender pacientes y participaran en la solución de un problema de atención sanitaria que en ese entonces era mucho más apremiante que ahora. Unos años después, los recién egresados de otras licenciaturas (pasantes) también fueron incorporados a esta estrategia y, al fin, se reconoció formalmente como una responsabilidad de las instituciones educativas. Las aportaciones del SS a la salud de las personas y a la formación de los médicos han sido incuestionables, y la experiencia humana que ha representado para quienes lo han vivido ha dejado marcas indelebles.

La estrella O4f LSS3074 fue descubierta como binaria espectroscópica de corto período y líneas dobles por Morrell & Niemela (1990, ASP Conf. Ser. 7, 57). Posteriormente, Haefner et~al.(1994, IBVS 3969) encontraron variaciones fotométricas, estimando una inclinación orbital entre 50o y 55o. Teniendo en cuenta la importancia de obtener valores empíricos para las masas de estrellas O tempranas, y considerando la gran dispersión existente entre los valores observados y su discrepancia con los predichos por los modelos teóricos, hemos obtenido nuevas observaciones espectroscópicas de este sistema, con el propósito de mejorar los elementos orbitales derivados en la solución preliminar. Además, como las estrellas O tempranas suelen formar parte de cúmulos y asociaciones OB, hemos llevado a cabo una investigación espectroscópica de varias estrellas tempranas que podrían estar físicamente relacionadas con LSS~3074.

    RIASSUNTO. Il fenomeno delle persone senza fissa dimora sta assumendo in questi anni una rilevanza sociale devastante, con una prevalenza stimata in USA e in Europa compresa tra il 5,6% e il 13,9%. Queste persone hanno una scarsa qualità di vita, una limitata o assente vita sociale, sono spesso disoccupate o lavorano solo saltuariamente. Sono a rischio di problemi con la legge, sono spesso affette da dipendenza da droghe, da patologie psichiatriche e internistiche. L'alcol spesso non rappresenta la causa della loro condizione sociale, ma solo la conseguenza, contribuendo in questo modo al loro degrado bio-psico-sociale. Nel 2009 lo US Department of Housing and Urban Development's Homelessness Assistance Programs e nel 2010 la European Consensus Conference on Homelessness hanno segnato un grande passo avanti nella riabilitazione sociale di queste persone, utilizzando il concetto del "case management". In particolare lo Standard Case Management si è dimostrato in grado di migliorare la stabilità abitativa, di ridurre l'uso di droghe e di rimuovere le barriere lavorative. L'Assertive Community Treatment si è dimostrato, invece, in grado di migliorare la stabilità abitativa e ha un rapporto costo/beneficio migliore per i pazienti affetti da doppia diagnosi.

    Objetivo: El propósito del presente trabajo es presentar los resultados de 36 pacientes con diagnóstico de neuralgia del trigémino (NT), en los cuales se realizó una descompresión microvascular (DMV). Material y Método: Desde junio de 2005 a mayo de 2012, 36 pacientes con diagnóstico de NT fueron operados por el primer autor (AC), realizando una DMV. Se evaluó: Edad, sexo, tiempo de sintomatología previo a la cirugía, hallazgos intraoperatorios (a través de los videos quirúrgicos), y resultados postoperatorios. Resultados: De los 36 pacientes operados, 25 fueron mujeres y 11 varones. El promedio de edad fue de 48 años. El seguimiento postoperatorio fue en promedio de 38 meses. De los 36 pacientes, 32 (88%) evolucionaron sin dolor hasta la fecha. De los 4 casos con recurrencia de dolor, en dos pacientes se observó como hallazgo intraoperatorio un conflicto venoso. Conclusión: La DMV como tratamiento de la NT es un procedimiento efectivo y seguro. El hallazgo intraoperatorio de una “compresión” venosa podría indicar una evolución postoperatoria desfavorable.

  3. Características del viento en estrellas Be derivadas del perfil Hα

    Rohrmann, R.; Cidale, L.

    El estudio teórico de perfiles Hα y su variabilidad en estrellas Be ha sido frecuentemente desarrollado en base a modelos de envolturas circunestelares inhomogéneas, donde la geometría del material es responsable de la forma del perfil dependiendo de la dirección de observación. Nosotros damos una interpretación alternativa y proponemos que la mayoría de las propiedades de esta línea tienen origen en la base de un viento estelar y de una estructura cromosférica anexa a la fotósfera. Encontramos que típicos perfiles Hα en Be, como son los llamados pole-on y winebottle, pueden ser reproducidos cualitativamente sin recurrir a la existencia de una envoltura asimétrica. Analizamos como la línea Hα permite identificar la posible estructura del viento en la región donde éste se inicia.

    Arroyo Betancourt, Luz I.

    Esta investigacion estudia la implantacion del enfoque constructivista en tres aulas de ciencia del contexto puertorriqueno. Se auscultaron las practicas educativas que utilizan maestras consideradas constructivistas y la correspondencia de sus practicas educativas con los elementos esenciales de la didactica que proponen los teoricos de los planteamientos constructivistas. Se ausculto, ademas, a que vision del enfoque constructivista responden las expresiones de las maestras acerca de su practica educativa y como compara con su quehacer, a la luz de los elementos esenciales de las visiones constructivistas piagetiana, social y radical. Se utilizo el diseno de estudio descriptivo de caso multiple. El estudio se baso en entrevistas a profundidad, revision de documentos y observacion no participativa a la sala de clases. El contexto fueron tres escuelas publicas de la Region Educativa de San Juan, una elemental, una intermedia y una superior. Los resultados confirmaron que la transicion hacia el enfoque constructivista es un proceso que toma tiempo, dedicacion y la participacion en adiestramientos y readiestramientos acerca del nuevo enfoque. Las maestras coinciden en la mayoria de las practicas educativas que utilizan para implantar el enfoque constructivista de ensenanza y difieren en algunas debido, probablemente, a que han tenido que adaptarlas a los correspondientes niveles de ensenanza: elemental, intermedio y superior. Dos de las maestras planifican por conceptos generadores, mientras que una de ellas planifica siguiendo la guia que recibe del Departamento de Educacion. Difieren ademas, en el enfasis que confieren al inquirir cientifico. Con relacion a la correspondencia entre la vision manifestada por las maestras a la luz de las visiones piagetiana, social y radical, aparentemente, las preguntas del protocolo de entrevistas no lograron evocar la informacion con suficiente profundidad, por lo que la investigadora tuvo que inferir las visiones de las participantes basado en lo que estas manifestaron en su practica didactica. Dos maestras coinciden en una vision constructivista social de la construccion del conocimiento, del aprendizaje y de los metodos didacticos. La otra manifesto una vision constructivista piagetiana en el aprendizaje, los metodos didacticos y en la construccion del conocimiento. Se espera que este trabajo, ademas de promover los estudios de caso sobre el enfoque constructivista de ensenanza en el contexto puertorriqueno, sirva para que los maestros, que estan transformando su enfoque educativo de uno tradicional a uno constructivista, tengan una vision mas clara de la implantacion de este enfoque. Se espera ademas que sirva para que el Departamento de Educacion y sus programas de adiestramiento y readiestramiento en servicio, asi como las universidades y sus programas de preparacion de maestros, tomen en cuenta los resultados y recomendaciones de este estudio al revisar sus programas.

    Abstract High sodium intake is 1 of the modifiable risk factors for cardiovascular disease, but in Korea, daily sodium intake is estimated to be double the level recommended by World Health Organization. We investigated the association between the estimated 24-h urinary sodium excretion (24hUNaE) and metabolic syndrome using nationwide population data. In total, 17,541 individuals (weighted n = 33,200,054; weighted men, 52.5% [95% confidence interval, CI = 51.8–53.3]; weighted age, 45.2 years [44.7–45.7]) who participated in the Korean Health and Nutrition Examination Survey 2009 to 2011 were investigated. NCEP-ATP III criteria for metabolic syndrome were used, and sodium intake was estimated by 24hUNaE using Tanaka equation with a spot urine sample. The weighted mean 24hUNaE values were 3964 mg/d (95% CI = 3885–4044) in men and 4736 mg/d (4654–4817) in women. The weighted age-adjusted prevalence of metabolic syndrome was 22.2% (21.4–23.0), and it increased with 24hUNaE quartile in both men and women (mean ± standard error of the mean; men: 22.5 ± 1.0%, 23.0 ± 1.0%, 26.0 ± 1.2%, and 26.0 ± 1.2%; P = 0.026; women: 19.4 ± 0.8%, 17.7 ± 0.8%, 19.8 ± 1.0%, and 23.0 ± 1.1%; P = 0.002, for quartiles 1–4, respectively). Even after adjustment for age, daily calorie intake, heavy alcohol drinking, regular exercise, college graduation, and antihypertensive medication, the weighted prevalence of metabolic syndrome increased with the increase in 24hUNaE in men and women. The weighted 24hUNaE was positively associated with the number of metabolic syndrome components after adjustment for confounding factors in men and women. In subjects without antihypertensive medication, the odds ratio for metabolic syndrome in quartile 4 of 24hUNaE compared with quartile 1 was 1.56 (1.33–1.84, P < 0.001) in the total population, 1.66 (1.34–2.06, P < 0.001) in men, and 1.94 (1.49–2.53, P < 0.001) in women. In this nationwide population study, we observed a significant independent association between high sodium intake, estimated by spot urine sodium excretion, and the presence of metabolic syndrome in men and women.

    2013-03-01

    In the pseudogap regime, high temperature superconductors often exhibit electronic structure, such as charge stripes. Charge stripes pinned to disorder have been predicted to contribute to low-frequency resistance fluctuations when sample dimensions are comparable to the size of stripe domains (Carlson, 2006). We are extending our previous studies of resistance fluctuations in YBa2Cu3O7-δ (Bonetti, 2004; Caplan, 2010) to thin films of La-based cuprates expected to have a more stable stripe phase, particularly in the regime near 1/8-filling. We present measurements of the low-frequency electronic transport in La2-xBaxCuO4 nanowires fabricated by pulsed laser deposition and lithographic techniques. We discuss temperature dependence of the power spectral density and its relevance to correlated electron phases above Tc. This research was supported by the DOE-DMS under grant DE-FG02-07ER46453, through the Frederick Seitz Materials Research Laboratory at the University of Illinois at Urbana-Champaign.

    2017-08-01

    In recent years, the PROBE Lab at the University of Illinois at Urbana-Champaign has made significant developments in plasmonic nanoantenna technology by more closely exploring the rich parameter space associated with these structures including geometry and material composition, as well as the optical excitation conditions. Indeed, plasmonic nanoantennas are attractive for a variety of potential applications in nanotechnology, biology, and photonics due to their ability to tightly confine and strongly enhance optical fields. This talk will discuss our work with arrays of Au bowtie nanoantennas (BNAs) with an emphasis on how their field enhancement properties could be harnessed for particle manipulation and sensing. We also present our work with pillar-supported BNAs (p-BNAs) and discuss their potential for sensing applications, particularly when adapted for response in the near-IR. The talk will conclude with a brief discussion of some of the future work pursued by the PROBE lab, including adapting BNAs for lab-on-a-chip applications.

    1984-01-01

    The positive intrinsic negative (PIN) diode switch which is designed to protect the receiver from burnout or damage on transmission and channel the echo signal to the receiver on reception is outlined. The receiver must be protected firmly. A schematic diagram of a transformer rectifier (TR-ATR) switch for the Urbana Radar is shown. The T/R switch consists of a half wavelength coaxial cavity with tuning condenser and PIN diodes. Two UM4300 PIN diodes were mounted between the inner and outer conductor. The dc biasing voltage required for the PIN diodes is supplied by a control circuit. On transmission, the PIN diodes are forward biased to about 0.5 amperes. On reception, about 10 volts reverse voltage is applied to the diodes, which produces an initial reverse current to speed the recovery time. The T/R switch characteristics are estimated and the result of testing at different peak transmitter powers from 410 kW to 1500 kW is shown.

    This report summarizes the activities conducted under the DOE-OE funded project DEOE0000674, where ABB Inc. (ABB), in collaboration with University of Illinois at Urbana-Champaign (UIUC), Bonneville Power Administration (BPA), and Ameren-Illinois (Ameren-IL) pursued the development of a system of collaborative defense of electrical substation’s intelligent electronic devices against cyber-attacks (CODEF). An electrical substation with CODEF features will be more capable of mitigating cyber-attacks especially those that seek to control switching devices. It leverages the security extensions of IEC 61850 to empower existing devices to collaborate in identifying and blocking malicious intents to trip circuit breakers, mis-coordinate devices settings, even thoughmore » the commands and the measurements comply with correct syntax. The CODEF functions utilize the physics of electromagnetic systems, electric power engineering principles, and computer science to bring more in depth cyber defense closer to the protected substation devices.« less

  11. The Singular Quest for a Universal Tree of Life

    2013-01-01

    Carl Woese developed a unique research program, based on rRNA, for discerning bacterial relationships and constructing a universal tree of life. Woese's interest in the evolution of the genetic code led to him to investigate the deep roots of evolution, develop the concept of the progenote, and conceive of the Archaea. In so doing, he and his colleagues at the University of Illinois in Urbana revolutionized microbiology and brought the classification of microbes into an evolutionary framework. Woese also provided definitive evidence for the role of symbiosis in the evolution of the eukaryotic cell while underscoring the importance of lateral gene transfer in microbial evolution. Woese and colleagues' proposal of three fundamental domains of life was brought forward in direct conflict with the prokaryote-eukaryote dichotomy. Together with several colleagues and associates, he brought together diverse evidence to support the rRNA evidence for the fundamentally tripartite nature of life. This paper aims to provide insight into his accomplishments, how he achieved them, and his place in the history of biology. PMID:24296570

    2011-01-01

    This presentation provides a high level overview of the Large-Scale Low-Boom Inlet Test and was presented at the Fundamental Aeronautics 2011 Technical Conference. In October 2010 a low-boom supersonic inlet concept with flow control was tested in the 8'x6' supersonic wind tunnel at NASA Glenn Research Center (GRC). The primary objectives of the test were to evaluate the inlet stability and operability of a large-scale low-boom supersonic inlet concept by acquiring performance and flowfield validation data, as well as evaluate simple, passive, bleedless inlet boundary layer control options. During this effort two models were tested: a dual stream inlet intended to model potential flight hardware and a single stream design to study a zero-degree external cowl angle and to permit surface flow visualization of the vortex generator flow control on the internal centerbody surface. The tests were conducted by a team of researchers from NASA GRC, Gulfstream Aerospace Corporation, University of Illinois at Urbana-Champaign, and the University of Virginia

    Two new species of Bibloplectus Reitter, 1881 are described from the Orlando Park Collection of Pselaphinae at the FMNH (Field Museum of Natural History, Chicago, IL, USA): Bibloplectus silvestris Owens and Carlton, new species (type locality, Urbana, IL, USA) and Bibloplectus wingi Owens and Carlton, new species (type locality, Shades State Park, IN, USA). Types of these new species were part of a series of specimens bearing unpublished Park manuscript names in both the pinned and slide collection at the FMNH. They bring the total number of species in the genus in eastern North America to twenty-three. Resolving these manuscript names adds to previous efforts to uncover elements of the hidden diversity of North American Bibloplectus from museum collections (Owens and Carlton 2016, Owens and Carlton 2017) and highlights the importance of close examination of the Orlando Park pselaphine collection as a valuable historic and taxonomic resource.

    Conjecture (C) 1: Coulomb-charged constituents of electron (e) are attracted to its barycentre by lepto-strong force F=K/r^2+f; f is stably perturbative for r < the "radius" of e. An exterior magnetic field (MF) with gradient (G) secularly perturbs the eccentricities but not the energies of the constituents' orbits, changing the spin (s) and magnetic moment (μ) of e. (C) 2: F coheres two or more e's dynamically with r approximately equal to the "radius" of e. The resulting MF and G at each e oscillate. Stable values of s and μ result for each e which differs from the atomic values. Binding energies change the masses of the e's. A hadron results. (C) 3: An e similarly may bind to a proton to form a Rutherford- Santilli neutron. The proton is negligibly mutated.(References: H. Dehmelt, Science 247, 539 (1990); T.E.

    This project funded the C 4 and CAM (crassulacean acid metabolism) Plant Biology 2013 symposium, held at the University of Illinois at Urbana-Champaign, IL, on August 6-9, 2013. The symposium brought together a diverse group of scientists to discuss the evolution, ecology, functional biology, genomics and biotechnological engineering of C 4 and CAM plants. These two groups of plants possess evolutionary modifications to their photosynthetic machinery that improve their performance in hot and dry conditions. Maize and pineapple are classic examples of C 4 and CAM plants, respectively. The meeting discussed how lessons learned from these groups of plants canmore » be harnessed to improve crop production of biofuel feedstocks in an era of global climate change. The interdisciplinary nature of the meeting meant that the delegation members typically do not collectively attend any one scientific society meeting. As a result, the symposium was a unique opportunity for knowledge transfer, initiation of new collaborations, and recruitment and exposure of early career scientists.« less

  16. An investigation of turbulent scatter from the mesosphere as observed by coherent-scatter radar

    Gibbs, K. P.; Bowhill, S. A.

    1983-01-01

    Turbulent scatter from he mesosphere is observed using the Urbana coherent-scatter radar. The variation in signal-to-noise ratio as a function of time-of-day is examined. The origin of scattering regions is investigated by comparing the variations in scattered power and Doppler velocity. Nighttime echoes are shown for periods of enhanced electron concentration. The spectrum of the returned signal is studied with a resolution of ten seconds. Spectral information is used to increase altitude resolution and observe the motion of scatterers. The expected variation in signal-to-noise ratio with solar flux is observed. It is found that variations in the scattered power generally do not correspond to the gravity waves which are simultaneously observed. Turbulent layers are observed at altitudes with high shear in the horizontal velocity and at altitudes with low shear. The ten-second resolution is necessary to distinguish meteor echoes from echoes produced by the advection of a scattering layer through the radar beam.

    An approach to produce graphene films by epitaxial growth on silicon carbide substrate is promising, but its current implementation requires the use of SiC as the device substrate. We present a simple method for transferring epitaxial sheets of graphene on SiC to other substrates. The graphene was grown on the (0001) face of 6H-SiC by thermal annealing in a hydrogen atmosphere. Transfer was accomplished using a peeling process with a bilayer film of Gold/polyimide, to yield graphene with square millimeters of coverage on the target substrate. Back gated field-effect transistors fabricated on oxidized silicon substrates with Cr/Au as source-drain electrodes exhibited ambipolar characteristics with hole mobilities of ˜100 cm^2/V-s, and negligible influence of resistance at the contacts.

    Meteoritic ablation in the upper atmosphere is the commonly accepted source of the mesospheric metals between 80 and 105 km. The vertical and temporal behavior of some of these metals can be probed with high accuracy and resolution using resonance fluorescence lidar techniques. Of considerable interest in recent years has been the sporadic and rapid formation of thin, dense enhancements in these metallic layers. Since late Mar. 1991, the UIUC CEDAR lidar system, located at the Urbana Atmospheric Observatory, has been routinely operating at the Fe resonance line of 372 nm in order to probe the mesospheric Fe layer. In Nov. 1991, the capability to investigate mesospheric Ca(+) at the resonance line of 393.4 nm was added. The lidar's eximer-pumped dye laser uses Exciton QUI laser dye dissolved in p-dioxane, which can lase at both the Fe and Ca(+) frequencies. Various aspects of this investigation are discussed.

    To see if there is a difference in performance when students switch from traditional paper-and-pencil examinations to computer-based examinations, and to determine whether there are gender differences in student performance in these two examination formats. This study involved first year medical students at the University of Illinois at Urbana-Champaign over three Academic Years 2002-03/2003-04 and 2003-05. Comparisons of student performance by overall class and gender were made. Specific comparisons within courses that utilized both the paper-and-pencil and computer formats were analyzed. Overall performance scores for students among the various Academic Years revealed no differences between exams given in the traditional pen-and-paper and computer formats. Further, when we looked specifically for gender differences in performance between these two testing formats, we found none. The format for examinations in the courses analyzed does not affect student performance. We find no evidence for gender differences in performance on exams on pen-and-paper or computer-based exams.

  20. IMIRSEL: a secure music retrieval testing environment

    NASA Astrophysics Data System (ADS)

    Downie, John S.

    2004-10-01

    The Music Information Retrieval (MIR) and Music Digital Library (MDL) research communities have long noted the need for formal evaluation mechanisms. Issues concerning the unavailability of freely-available music materials have greatly hindered the creation of standardized test collections with which these communities could scientifically assess the strengths and weaknesses of their various music retrieval techniques. The International Music Information Retrieval Systems Evaluation Laboratory (IMIRSEL) is being developed at the University of Illinois at Urbana-Champaign (UIUC) specifically to overcome this hindrance to the scientific evaluation of MIR/MDL systems. Together with its subsidiary Human Use of Music Information Retrieval Systems (HUMIRS) project, IMIRSEL will allow MIR/MDL researchers access to the standardized large-scale collection of copyright-sensitive music materials and standardized test queries being housed at UIUC's National Center for Supercomputing Applications (NCSA). Virtual Research Labs (VRL), based upon NCSA's Data-to-Knowledge (D2K) tool set, are being developed through which MIR/MDL researchers will interact with the music materials under a "trusted code" security model.
