A food preparation apparatus having a food carrier holding one or more articles of food being removeably positioned on a transport mechanism for travel in a linear direction and being simultaneously rotated and advanced subjecting the food to a predetermined level of cooking heat wherein the carrier has a predetermined weakened area for improved handling of the food after cooking. The substrate comprises a substrate material; a primer layer formed on the substrate material; and an immobilization layer formed on the primer layer. The total yield of arylalkyl carbonate and diaryl carbonate together is at least 40%. The base plate includes a base portion and a raised portion. The tributary card transmits information to the cross-connect card in a first out-of-band signal over the link and the cross-connect card broadcasts the information to the plurality of cards in the network element in a second out-of-band signal. A free resource stack identifies available resources, and a process queue identifies pending processes waiting for released processes.
