the separation of olefin/paraffin mixtures is an important process in petrochemical industries, which is traditionally performed by low temperature distillation with a high-energy consumption, or complex extractive distillationand adsorption techniques. membrane separation process is emerging as an alternative for traditional separation processes with respect to low energy and simple operation....

nothing affects learners more than assessment, so it is important to involve them in assessment process. involvment of learners in assessment helps them to become autonoumos learners. despite this importance iranian learners specialy javanroodian ones are not activily involved in the process. hence the aim of this thesis is to invesrtigate thier ability in th eassessment process

During the last five years the recognition of ionic channels in the parietal cells of stomach and acid chloride mechanisms of secretion by these cells has become totally clear by the "Patch Oamp" technique. The apical cytoplasm in the oxyntic cells are in the form of vesicles where membranes contain H+, K+ -ATPase pump. Stimulation causes fusion of these tubular vesicles with the cell membran o...

traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. to design a membrane process for olefin-paraffin separation, equilibriu...
