The invention provides methods and compositions useful for making synthetic peptide conjugates. Such semiconductor memory includes a memory array, the memory array including a plurality of memory cells which are accessible through a plurality of respective wordlines and a plurality of respective bitlines. The score and associated data are stored in a central server with a searchable database that communicates with one or more third party application servers. The method uses techniques for the correction of the Optical Signal to Noise Ratio induced error as well as the Spectral Filtering Error during the loss computation required for adjusting the gains of the amplifiers at each network node to an appropriate value. The apparatus may be built into the box lid, or may be provided as an aftermarket or OEM attachment. The string is moved so as to move the boring tool further downwards and the inclination of the probe is detected again in order to check that verticality has been reached.
