Análisis de la acidez de la precipitación en la Península Ibérica
Marín, E.; Lavín, N.; Hernández, E.; Rúa, A.ACIDITY OF PRECIPITATION IN THE IBERIAN PENINSULA – Acidity of precipitation in the Iberian Peninsula between 1986 and 1997 is studied in this paper. The main objectives are the analysis of its variability, seasonal cycle, and trend. The results show a higher acidity of precipitation in Portugal than in Spain, although precipitation is acid in both countries. In general, the pH variability is lower in Portugal ...
MATLAB GUI for computing Bessel functions using continued fractions algorithm
Hernández,E.; Commeford,K.; Pérez-Quiles,M.J.Higher order Bessel functions are prevalent in physics and engineering and there exist different methods to evaluate them quickly and efficiently. Two of these methods are Miller's algorithm and the continued fractions algorithm. Miller's algorithm uses arbitrary starting values and normalization constants to evaluate Bessel functions. The continued fractions algorithm directly computes each value, keeping the ...
Study of the antibody response against Mycobacterium tuberculosis antigens in W...
Araujo,Z; Waard,JH de; Fernández de Larrea,C; López,D; Fandiño,C; Maldonado,A; Hernández,E; Ocaña,Y; Ortega,R; Singh,M; Ottenhoff,Tom HM; Arend,SMThis study was aimed at investigating alternate methods for serodiagnosis of tuberculosis (TB), which are needed because bacteriologic diagnosis of childhood TB is difficult. A selection of 80 serum and saliva samples were tested from Warao indigenous children under 15 years of age; 34 high TB suspects (28 positive and 6 negative for the tuberculin skin test, TST) and 46 healthy contact children (32 positive an...
