The present invention concerns a mechanical method for generating nanostructures in order to obtain on a surface of a metal piece a nanostructured layer of defined thickness. Each processor is operable in a \u201ccompatible\u201d mode, in which all processors within a family accept the same baseline command set and produce identical results upon executing any command in the baseline command set. A hand guard is coupled to the receiver. If there is a corresponding pointer, a memory read response may be sent to the requesting agent. The surface treating agent for ligneous floorings contains a drying oil, Japan wax, candelilla wax, and powdery carnauba wax.
