A downhole shock absorber preferably is filled with well fluid in a chamber that is reduced in volume due to impact. The core assembly comprises an intake section, a diverter section and an output section. Serial data received from the testing device is organized into a parallel format to display predicted versus actual data values on a per node basis, to show how a node is passing or failing. In indirect communication, data is first sent to an intermediate node via links connecting the source and intermediate nodes. Anti-inflammatory compositions containing TSP are particularly useful for topical administration in the treatment of inflammatory diseases of the skin and mucosa. The dynamics model represents movements as a movement of a body material particle or the like and a rotational movement of a flywheel.
