The present invention is a nondestructive and quantitative laser ultrasonic laser apparatus and associated method for determining adhesion quality of a coating on a substrate. After released from the unit memory block, the objects are added on a free re-use list so as to be reused when there is an invocation of allocation for the same object size. The second scrambling identifier is different from the first scrambling identifier. In another embodiment, the peptide mimic and spacer are linked to a carrier molecule. A capacitor has one end that communicates with the input of the zero-order TIA.
