the analytical theory of one dimensional, dispersion free miscible displacement of oil by injection gas with nc component has shown that: the mmp is the lowest pressure at which any one of the initial oil, injection gas or crossover key tie lines becomes critical, which means that its length approaches to zero. in this paper, we propose a method for a solving multi component system based on ana...

SF6, which is currently widely used in gas-insulated power transmission equipment, a greenhouse gas with very strong effect. Therefore, developing environmentally friendly insulation equipment to gradually reduce the use of SF6 has become hot research topic. As most potential alternative gas, C4F7N great significance study electrical characteristics medium-voltage switching field promote green ...

Significant controversy exists regarding vesicoureteral reflux (VUR) management, due to lack of sufficient prospective studies. The rationale for surgical management is that VUR can cause recurrent episodes of pyelonephritis and long-term renal damage. Several surgical techniques have been introduced during the past decades. Open anti-reflux operations have high success rate, exceeding 95%, and...

Modern marine vessels use electrically driven rudders; cruise liners, gas carriers, tankers are equipped with Azipod systems manufactured by the Swedish-Swiss company ABB. Gondola-type propellers make it possible to break ice when vessel is moving astern, therefore such used for work on Northern Sea Route, in particular, working Yamal LNG project. The 22MW propulsion system rotates 360° and ena...

iran's proved natural gas reserves are the world's second largest reserves. mainly, because of different climate changes and different reservoirs characterizations, studying the behavior of producing outcome fluids and their transportation, is of major interest. one of the main problems occur in the gas reservoirs is related to the hydrate formation while producing from a well, either in produc...
