The study examined differences in HIV testing between men who have sex with men only (MSMO) (n=300) and men who have sex with men and women (MSMW) (n=105) and assessed associations with HIV testing among MSMW. A venue-based cross-sectional HIV surveillance study in 2008 (BESURE-MSM2) was examined. Prevalence of HIV testing was similar for MSMO and MSMW. One-on-one counseling (excluding counseli...

The relationship between reaction time and visual latcncy rclative to a fixed stimulus has been measured in haploscopic vision by means of the flicker effect produced by two stimuli of different luminance levels. The fields of foveal vision wcrc of 5 0 , thc retinal illuminance was from 8 to 110 td and three obscrvcrs wcrc used. The results show in all cases that the motor componcnt in ...

This paper reports stochastic properties of renewable wind and solar energy resources by studying their conditional probability distribution functions (cpdf) in different time lags. The empirical results are obtained for data of global horizontal irradiance measured by a single sensor and the power output of a single wind turbine, as well as for an averaged solar sensor field and an aggregated ...
