CATALYTIC CONVERTER FAILURES: If a catalytic converter needs replacing, one of the problems below most likely contributed to its failure. Engine Tune-Up Required. A number of problems could occur to the catalytic converter as the result of an engine that is out of tune.

The best documented effects of electrical stimulation on skeletal muscle are those that occur after chronic, low-frequency stimulation (similar to the activity of a slow muscle) is imposed upon a predominantly fast muscle.n fact, even the physical appearance of the stimulated muscle approaches that of the more postural muscles by taking on a deep red appearance. Time course of muscle fiber transformation: If low frequency stimulation is applied 8-24 hours per day, the total transformation process requires about 8 weeks.
