The external muscle layer of the mammalian esophagus consists of striated muscles. We investigated the contractile properties of esophageal striated muscle by comparison with those of skeletal and cardiac muscles. Electrical field stimulation with single pulses evoked twitch-like contractile responses in esophageal muscle, similar to those in skeletal(More)
We can make optimum scheduling results using various methods that are proposed by many researchers. However, it is very difficult to complete the processes on time without delaying the schedule. There are two major causes that disturb the planned optimum schedules; they are (1)the variation of productive capacity, and (2)the variation of products'(More)
