A synthesis plant includes a separation system upstream of a synthesis loop that removes excess nitrogen and other gaseous compounds from a feed gas having a ratio of hydrogen to nitrogen of less than 3:1, thereby producing a syngas with a ratio of hydrogen to nitrogen at about 3:1. The polyanionic bioactive agent in the microspheres andor nanospheres is preferably condensed using a polycationic condensing agent, such as poly-L-lysine. The wheel includes a first portion positioned in an inlet air path and a second portion positioned in an outlet air path. A plating electrode is formed on the second face. On the other hand, when a short-circuited FET is identified as one of high-side FETs, minimum phase voltages of the three phases are detected when a steering operation is performed by the driver, and the detected minimum phase voltages of the three phases are compared with one another to identify a short-circuit phase.
