A pharmacologic agent for treating andor preventing cancer, among other diseases and conditions, and particularly breast, prostate, and pancreatic cancer, in humans and animals. From a time of step-in to a time of kick-out of a block, the effect of shearing strain which is transmitted to a trailing edge from a preceding trailing edge portion is mitigated, and movement of the trailing edge of the block with respect to a road surface is suppressed. Each of the delay elements steals a portion of a clock cycle from subsequent circuits to provide a more reliable logical function, and to avoid the need for overall additional clock cycles. Bedding material can be sifted out of the basket while retaining the animal waste. Regeneration of specially prepared adsorbent allows the adsorbent bed to warm up to temperatures that preclude the use of requiring either vacuum or evacuation of adsorbent from the bed. By means of the vibration blocks, the sensing area as well as the driving amplitude of the gyroscope can be increased effectively.
