Sandra Isabel García Mora
NURE Investigación , 2011,
Abstract: The primary prevention of the cardiac sudden death constitutes one of the main challenges of the present cardiology. The main reason for this interest comes dice by the little possibilities of surviving an extra-hospital cardiac shutdown, smaller of 20%.El implantable automatic fibre-removing machine (DAI) is the most effective therapy to prevent the cardiac sudden death related to ventricular tachyarrhythmias. From the beginnings of the therapy by means of the DAI, besides the survival and the quality of life of the patients it has constituted an important reason for attention. The carrying patients present/display agreements that can have an excellent impact in their quality of life. The infirmary personnel must know the therapy the DAI, to be able to provide to the patients and their familiar surroundings the optimal cares to confront its daily life, a level of confidence and comfort derived from the positioning of a permanent electronics.

Revista internacional de contaminación ambiental , 2005,
Abstract: El relacionar el uso de fertilizantes químicos u orgánicos nitrogenados con la contaminación ambiental, implica adoptar alternativas que reduzcan las pérdidas de nitrógeno (N) del suelo que podría ser utilizado por los cultivos. La fertirrigación es una técnica de aplicación de agua y fertilizante que mejora la eficiencia en el uso de los fertilizantes mediante el riego por goteo. No existen reportes sobre como la fertirrigación afecta a la desnitrificación. El objetivo del presente trabajo es estudiar cómo afectan la fertirrigación y la fertilización convencional a la desnitrificación y verificar si, efectivamente, es posible reducir las emisiones de óxido nitroso (N 2 O) hacia la atmósfera. Se utilizó la captura de N 2 O in situpor el método adaptado por Grageda (1999) y Vivanco (2000). Las muestras de N 2 O se tomaron a las 2, 24, 48 y 72 h después del riego. La temperatura del suelo se midió con un termómetro aproximadamente a 10 cm de profundidad del suelo. La humedad del suelo (0 12 cm) se determinó con la ayuda de un instrumento DT DeltaT devices, tipo ML2 ThetaProbe. La cuantificación de N 2 O fue por cromatografía de gases. Los cálculos y análisis estadístico se efectuaron con el paquete estadístico SAS (SAS 1998). Los resultados obtenidos para la emisión de N 2 O manifiestan que el factor que más influyó en el sistema de riego convencional fue la humedad ya que existió una diferencia significativa a las 2, 24 y 48 h después del riego con respecto al fertirriego (riego por goteo). A pesar de que estadísticamente no hubo diferencia significativa en la emisión de N 2 O entre sistemas se obtuvo una concentración en riego por goteo de 0.69 y 2.82 mM menor que en el sistema convencional a las 48 y 72 h. Las temperaturas registradas a lo largo del desarrollo del cultivo estuvieron por debajo de las reportadas, por lo que se asume que este factor influyó en la disminución de la producción de N 2 O. Con respecto al pH del suelo se trabajó en un rango de 8.0 a 8.4, promedio superior al reportado como pH óptimo para el crecimiento de brócoli por lo que probablemente también influyó en la emisión de N 2 O en el sistema convencional y en el fertirriego.

Abstract: En este artículo se analiza de forma comparativa la influencia de la resistividad del suelo y la resistencia de la falla en un método basado en la estimación de la impedancia para localización de fallas. Las pruebas se realizan en un sistema real de distribución, usando medidas de resistividad tomadas directamente en campo, así como valores de las resistencias de falla comúnmente encontradas para estos sistemas de potencia. Según los resultados en un sistema de distribución de 34,5 kV, los modelos de resistividad que mejor representan a los sistemas reales permiten obtener mejores resultados en la localización de fallas. dicionalmente, en la medida que el valor de la resistencia aumenta, menor es el desempe o del localizador, lo cual muestra la gran influencia de esta variable. De otra parte, se demuestra la influencia de la resistividad del terreno en la estimación del sitio de falla, en aquellos casos donde existe corriente de secuencia cero.

Abstract: the influence of the soil resistivity and the fault resistance is considered in this paper where a comparison of a well defined impedance based method for locating faults is presented. tests were performed in a real power distribution system, using soil resistivity measurements and a range of fault resistances commonly found in such systems. according to the results in a 34kv power distribution system, it is notice that the soil resistivity models which best represents the real systems are those which give better results in the fault location. additionally, the higher the fault resistance is, the lower the performance index is, showing the influence of this variable. finally, the influence of the soil resistivity in the distance estimation in such faults where the zero sequence current is different from zero is also analyzed in this paper

Abstract: Objective: To know the natural history of the first wave of pandemic influenza A(H1N1)pdm09 in the Southern hemisphere, through the detection of antibodies against influenza A(H1N1)pdm09 in a selected community, to estimate the population attack rate and its variations, the consultation rates, hospitallization and mortality rates. Methodology: A representative random sample of the population of a commune in Chile (San Felipe) was interviewed and taken blood samples between January and March 2010. A study against the antibodies of the influenza A(H1N1) pdm09 virus was conducted, by the technique of the Hemaglutination Inhibition (HAI) according to standardized methodology. Subjects with antibody titers ≥1:40 were considered positive. Results: 13.5% of the population of San Felipe had antibodies against influenza A(H1N1)pdm09; this percentage reached 30% of the population between 0 and 18 years and 6.1% among those over 19 years. The age variable was the only factor that evidenced significant differences in the prevalence of antibodies. There were no significant differences related to gender, vaccination history against seasonal inluenza, or comorbidity. 51% of people with positive serology showed IN-FLUENZA-LIKE SYMPTOMS. Conclusions: A relevant percentage of subclinical disease was detected in the first pandemic

wave in Chile and the proportion of people with SARI and deaths was small. Data from epidemiological surveillance were useful to estimate the trend of TSI but not its magnitude.
