A crop harvesting header includes a cutter bar mounted on a frame carrying a plurality of generally horizontal cutter disks. More particularly the invention relates to the improved and more efficient instrumental features of equipment used as e. The method also includes determining a difference between the price by the at least one vendor and the price by the at least one buyer. For example, the invention provides beverages including the formulations of the invention. The higher harmonic wave generating section adds the frequency component and a nonlinear process signal in which positive and negative signs of a frequency component for which the higher harmonic is to be generated are retained and which broadly monotonically increases nonlinearly with respect to the frequency component when the frequency component is located at least in the vicinity of zero. Each of the slots has a slot length that extends in horizontal and vertical directions, and the rollers each generally extends in a third direction orthogonal both to the horizontal and vertical directions.
