The efficient use of available energy in hydrocarbon extraction processes is essential to reducing overall emissions the petroleum industry. inefficient design an process leads higher per unit mass recovery. Fluid friction and heat transfer are irreversible that vital decreasing system’s operational efficiency. To reduce these losses reservoir production’s life, contributing factors such as cha...

Treatment of tobacco BY-2 cells with 10 mM caffeine that was started after the cells had entered the mitotic phase did not completely inhibit the deposition of callose in the cell plate and allowed the centrifugal redistribution of phragmoplast microtubules. On the other hand, when treatment with caffeine was started before the cells entered the mitotic phase, the deposition of callose was comp...

The purpose of this work is investigation the distribution gas phase velocity and liquid irrigation density at outlet heat exchange tube a vertical falling film evaporator. Experimental studies hydrodynamics two-phase flow were carried out on pilot instalation. Radial distributions various distances from lower section heating are obtained. It established that high velocities contribute to turbu...
