since the pressure of hydrocarbon reservoirs drops due to production, in order to keep the production rate constant or increase enhanced recovery, few methods are used. one of which is gas injection to the reservoir. on the other hand, due to reduction in oil production potential of aghajari oil field, gas injection is highly required to pressurize and enhance oil recovery. there is a possibili...

During bistable vision, perception oscillates between two mutually exclusive percepts despite constant sensory input. Greater BOLD responses in frontoparietal cortex have been shown to be associated with endogenous perceptual transitions compared with "replay" transitions designed to closely match bistability in both perceptual quality and timing. It has remained controversial, however, whether...
