Subject of the present invention is a new improved process for the preparation of nitroorotic acid via nitration of orotic acid. Accordingly, additional bits resulted from increase of a number of intra prediction mode are effectively reduced. The device may be incorporated with the AED pad for implementation in conjunction with defibrillator machine. In one embodiment, all of the encrypted session keys are stored together in a main message header. The processor is integrally formed in the substrate and is in communication with the trench. The electromagnetic wave detecting device has a characteristic that the active matrix array is formed by having a resin substrate as its base.
