A novel maize variety designated PH926 and seed, plants and plant parts thereof. The article is irradiated with a source of fast neutrons, and fast neutrons released by the fissile or fissionable material, if present, are detected between source neutron pulses. The illustrative embodiment comprises: an automatic protection switching channel that defines an address space in the telecommunications network; a node that is uniquely identified by an address in the address space; and a node that is not uniquely identified by an address in the address space. Materials that may be deposited by the method include ruthenium, tantalum, tantalum nitride, tungsten or tungsten nitride. Circuit boards formed by the method are also provided. This device includes a laser interferometer capable of generating a laser beam directed towards the wafer and detecting light reflected from the wafer, and a window disposed adjacent to a hole formed through a platen.
