Self-Validating Thermocouple Systems capable of detecting sensor probe open circuits, short circuits, and unnoticeable faults such as a probe debonding and probe degradation are useful in the measurement of temperatures. An upper segment determination section obtains address range information under an upper router which is connected on an external network side of a router to which the communication apparatus is connected. In one presently preferred embodiment of the present invention, the bio-active compounds are extracted from fenugreek seeds. Finally, the present invention relates to processes for producing arsenic disulfide. The sheeted material also includes a plurality of side sheets formed integrally with the main sheet which are arranged to be suspended from respective sides of the main sheet in an extended position of the sheeted material for enclosing the planted area.
