A spectrum channel sharing system may coordinate a shared usage of one or more spectrum channels between a first communication system and a second communication system. The machine is electronically controlled and replaces the difficult, dangerous and time-consuming operation of hand-peeling such logs with a drawknife. 01% to 10% of at least one hydroperoxide compound with at least one hydroperoxide groups attached to a tertiary carbon; 5% to 95% of at least one finely divided filler; 0% to 25% of one or more components selected from a solvent, a photoinitiator, a stabilizer, andor an antimicrobial agent. All of the optimizations are automated in a compiler with the help of minor annotations by the protocol designer.
