This invention relates to the use of tumor-derived or associated extracellular ribonucleic acid found circulating in the plasma or serum fraction of blood for the detection, monitoring, or evaluation of cancer or premalignant conditions. The integrated coil assembly has multi-phase coils with each multi-phase coil having a number of coil loops based upon the number of electrical phases of current required by the multi-phase linear motor. Said sait is subsequently treated with mineral or organic acid to yield high-purity meloxicam. The buffer accumulates partial image data, which is a part of the image data accumulated in the memory. Wire ends of the stator coil are each wound around a terminal and fixed thereto such that one part of the wound wire end is left free from the terminal, whereby disconnection of wires is avoided. Alternatively, the rear panel may be reversed in orientation relative to the front panel so that the cover may be folded and stuffed in between the mutually facing reverse surfaces of the front and rear pillowcase panels and encapsulated within the pillowcase by closure of the releaseable fasteners.
