A method for producing an optical information recording medium includes the steps of: coating a solution for forming a dye recording layer onto a surface of a rotating disc-shaped resin substrate; and discharging a cleaning solution from a nozzle onto a peripheral edge to remove the dye recording layer from the peripheral edge, wherein discharge of the cleaning solution is initiated 1. The present invention also provides expression constructs containing the polynucleotide molecules useful for modulating transgene expression in plants. The sprinkler system would use a series of nozzles connected to a common manifold and integrated therein a building structure’s roof vents. The invention accumulates the results of the recursive operations and uses the accumulated results to form a down-converted signal. The signal combiner combines the filtered single-carrier signal with the multi-carrier signal while maintaining phase, gain, frequency and timing alignment.
