A telecommunications system comprises a transmitter within the central terminal for sending a data message destined for a particular subscriber terminal over communication channels as a number of data blocks. The additive contains catalyst, seeding agent, excess reactant, quenching agent, carrier, or any combination thereof to modify reaction kinetics to preferentially crack these undesirable components that typically have a high propensity to coke, and are often precursors to coke in the coking process. The canister is mated to an injection nozzle to allow fluid flow from the canister though the nozzle and possibly into a body to be provided with fluid. The composite, which is wear-resistant and retroreflective, is useful as a traffic marking. The depression can be utilized by placing one or more memory or selection layers in the depression, and a via can be formed over a portion of the trench to form an interconnect.
