A self-clocking memory device comprises a memory array, a memory input circuit, and a memory control circuit. In at least one embodiment, a boot, which extends around the foot and lower leg, is secured around each foot. The invention still further includes a kit comprising a eukaryotic histone H1-containing antibiotic pharmaceutical composition and an instructional material which describes the use of the composition. The custom equation is converted into a standard equation that produces the developed length and is accepted by a modeling kernel of the solid modeling application. The color difference between the provided pigment and the resultant pigment is not more than about 5. The control circuit includes a first low voltage source, a second low voltage source, and a first switching device coupled in series with the first low voltage source and configured to create a first current path with the first low voltage source when in a closed position.
