Various embodiments of a system and method for order processing state management are described. The present invention relates to a process for purifying an electroluminescent material, the process involving treating, with a phosphorus-containing material, an electroluminescent material that contains Pd as an impurity so as to remove the Pd. Thus, debilitating side effects associated with use of pharmacologic agents that stimulate adrenergic receptors and display sympathomimetic effects can be reduced. The receiver multiplies the data sequence with the prescribed periodic sequence to form another watermarked signal and determines whether the watermarked signals match. The binding member includes a binding member reset surface aligned with a reset surface for engagement therewith to allow reuse of a shielded needle apparatus.
