A fluid for traction drives for automobiles which comprises a hydrocarbon compound having two bridged rings selected from bicyclo2. The system further includes a series of tumble dryers that extend from the first zone, through the second zone and into the third zone, and an HVAC unit that provides air to the first, second and third air handler units. The contacts are formed against and abutting the alignment rib, thereby ensuring coplanarity of the contacts for surface mounting to a circuit board. Serving cell system information block messages may also be modified or new SIB messages introduced to facilitate computation of an SNIR metric at a UE.
