several processes have been proposed for natural gas liquefaction due to the vast utilization of lng as a reliable and relatively easy to use fuel. even though the merits and demerits of different process have been studied, a dearth of comprehensive technical and economical comparative investigation of these methods makes further broad examination a necessity. this article is presented to addre...

The experimentation was carried out in stainless steel reactor using solutions different concentrations KOH (2.0, 2.5 and 3.0 M), at constant temperature 150 ℃ contact time between solution 24, 48 72 h. product obtained characterized by means scanning microsc...

The dynamical behavior of a map on the unit interval has been the subject of much contemporary research. In this paper, we will consider the relation between the continuity of the map cof and cof for some positive integer k, where f is a continuous map from the unit interval to itself, and ?f is a function which takes any element of the unit interval to the set of all subsequential limits o...
