    Análisis de expresión de genes de Mycobacterium tuberculosis durante la infección a macrófagos por Barrios García, Hugo Brígido

    Publicado 2006
    “…Abstract M. tuberculosis virulence factors have not been completely identified. In this work, the cytotoxic effect produced by M. tuberculosis on human macrophages and the expression of specific bacterial genes during macrophage infection that may be involved in mycobacterial virulence was analysed. …”

    Los tamaños de las muestras en encuestas de las ciencias sociales y su repercusión en la generación del conocimiento (Sample sizes for social science surveys and impact on knowl... por Rositas Martínez, Juan

    Publicado 2014
    “…Methods and formulations were investigated to determine the sample sizes that contribute to have good levels of estimation when establishing confidence intervals, with reasonable wide and relevant and significative magnitudes of the effects. Practical rules suggested by several researchers when determining samples sizes were tested and as a result it was integrated a guide for determining sample sizes for dichotomous, continuous, discrete and Likert variables, correlation and regression methods, factor analysis, Cronbach's alpha, and structural equation models. …”
