The present invention provides recombinant DNA molecules comprising a sequence encoding a pseudorabies virus glycoprotein selected from the group consisting of gI, gp50, and gp63, host cells transformed by the recombinant DNA molecule sequences, the gI, gp50 and gp63 polypeptides. The apparatus securely accepts a model structure, secures a force measurement component between the model structure and a force application component, and applies an incrementally increasing force until the workpiece fails. The each group of vessels may extend from a central region of the first portion to the periphery of the central portion. If there is no response, and without again maintaining another unmodulated carrier field for a specific period of time, the NFC device polls using a second modulation that is greater than the first modulation and waits again for a response. The plurality of gas exit apertures is configured to provide venting of at least one of moisture and outgassed material and the device coupling area is configured to receive an electronic device coupleable to the plurality of dielectric layers.
