A cleaning kit operable by a tool for cleaning pipes and fittings to prepare same for soldering. The evaluation results include a listing of each detected error, if any. To map these bulk rock properties, the interaction of the two seismic waves as they propagate through elastically nonlinear rocks is recorded. Thus an assay of HDL protective andor repair activity provides a highly effective assay for risk of atherosclerosis and its associated pathologies and such assays are provided herein.
