Methods and devices for automatically managing audio air control messages on an aircraft are described. Operability of the resource manager may be identified based on a reply of the resource manager to the emulation request. Additionally provided are products for inhibiting the fading of color and increasing the intensity of color in color-treated keratinous fibers. If the modelled peak amplitude in the symbol exceeds the threshold, the symbol stored in the buffer 158 is regenerated. The site specific enhancement of cytokine release is achieved by initiating an inflamatory response by laser therapy. Based on the ability of a transform function to minimally define the coded signal, an inverse transform function is selected to decode the signal.
