ABSTRACT

This paper focuses on the estimation of the UV Index (UVI) for all sky conditions using a simple analytical parameterization involving three independent variables: the solar zenith angle, the total ozone column and the clearness index. Measurements of the UVI made at Badajoz and Cáceres (Southwestern Spain) from January 2006 to December 2007 are used to estimate optimal fitting parameters for the model formula, while measurements from January to December 2008 are used to show that the formula-based estimations have mean absolute errors lower than 6% and R(2) ca 0.99.

ABSTRACT

En 100 donantes de sangre sanos, de ambos sexos, con edades comprendidas entre 20 y 40 años fueron determinados los valores de fosfatasa alcalina leucocitaria (FAL). Se utilizaron los métodos citoquímicos: Gomori Takamatzu y el de Burstone. Con el primero se encontró un valor escor de 30 a 140, con un promedio de 75.68 y una desviación normal de 30.62. Con el segundo se encontró un valor escor mínimo de 22 y un máximo de 150; promedio de 83,15 y desviación normal 31.49. Ambos métodos son comparables y los resultados obtenidos son válidos como valores normales de nuestra población sana
