Recycling appraisal

Approach to Equilibrium As equilibrium is approached the rate of reaction falls off, and the reactor size requireci to achieve a specified conversion goes up. At some point, the cost of increased reactor size will outweigh the cost of discarded or recycled unconverted material. No simple rule for an economic appraisal is really possible, but sometimes a basis of 95 percent of equilibrium conver-... 

The autocatalytic biochemical model with recycling of product suggests that birhythmicity could occur in neurons of both the inferior olive and the thalamus. A detailed appraisal of the role played by the oscillatory dynamics of the olivary neurons in the coordination of motor control has recently been given by Welsh et al. (1995).
