The invention provides novel methods of processing grain, such as corn and soybeans, utilizing thioredoxin andor thioredoxin reductase to enhance extractability and recovery of starch and protein. Infectious waste is introduced directly into the impactor, where the waste is pulverized, then introduced into the mixing drum through its inlet end for mixing with a treatment fluid effective to kill pathogenic organisms. A carrier is arranged to travel along a path parallel to the first and second conveyors, and a diverter element is affixed to the carrier and extending across at least a portion of the conveying surfaces of the first and second conveyors to divert articles in the stream on the first conveyor to the second conveyor. The DUT may tune to a given radio channel on the test signal. The advantage of the present invention that it is an independent method and therefore generally applicable and useful irrespective of the type of leaf sequence algorithm and delivery machines.
