A process for modifying a polymeric surface, the process comprising; contacting the polymeric surface with a solution comprising at least one ethylenically unsaturated monomer; and exposing the polymeric surface in contact with the solution to ultra-violet light to provide a graft-polymer of the monomer coated on the polymeric surface. The rubber composition is characterized by enhanced flame resistance. The Y-connector is also in fluid communication with a third line which connects the Y-connector to a suction source which supplies a suction force and receives the fluid. The special parameter set includes at least one parameter among multiple parameters in multiple network protocol headers for a data packet that includes a short message. The method includes adjusting engine operation responsive to exhaust gas sensor degradation, the degradation identified during deceleration fuel shut-off and compensated based on whether vapor purge operation is occurring in the engine during DFSO.
