A field generation unit generates a rotating magnetic field including a first partial magnetic field in a first position and a second partial magnetic field in a second position. The polymeric foundation system includes polymeric wall panels and other components suitable for withstanding lateral and end compression loads. A first fluid can be disposed within the bore. The first circuit produces a first rich electrolyte solution, which can be forwarded to primary metal value recovery, and a low-grade raffinate, which is forwarded to secondary metal value recovery. The casual storage field can receive an information element from another application program, display the received information element in the display region of the casual storage field, and hand over in response to a user instruction, the information element to yet another application program.
