By considering a device life and time needed for data migration, data stored in a storage apparatus is securely preserved until a retention term of each of the data. Said control block also comprises an oil channel which runs through at least one control block element for controlling the temperature thereof independently of the control of the valve arrangement. By such means yield of the integrated circuit is increased as well as the reliability of a device containing the integrated circuit. The method includes providing a single crystal substrate comprised of gallium nitride having a dislocation density less than about 105 per cm2, and homoepitaxially forming at least one semiconductor layer on the substrate. Expandable bellows in the pair of chambers communicate with the computer controlled fluid pressure pump to extend and retract the bellows and associated piston either alternatively or simultaneously. The practice of the present invention can be used to diagnose andor treat a subject having the identified DNA alterations by developing therapeutics, to prevent or delay the onset of associated diseases andor dysfunctions.
