Although active life style is one of the main determining factors of health, the level of regular physical activities in women is less than in men and even this level decreases with aging. The aim of this study was to determine the effect of an intervention based on the social ecological model on promotion of physical activity among female employees. In this study, 160 women employed at Shab...
gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...
