Disclosed is substantially pure DNA encoding an Arabidopsis thaliana Rps2 polypeptide; substantially pure Rps2 polypeptide; and methods of using such DNA to express the Rps2 polypeptide in plant cells and whole plants to provide, in transgenic plants, disease resistance to pathogens. Fins of different crystal orientations for PMOS and NMOS MuGFETs are formed through amorphization and crystal regrowth on a direct silicon bonded hybrid orientation technology substrate. Different ranges of addresses in the memory may be redistributed among a second set of functions in a second pipeline without waiting for the first set of functions to be flushed of data. The gain enhancement control signal decays exponentially so as not to excite mechanical resonance of the actuator arms. Also disclosed is the use of the composition for neutralizing or removing an acid from a refrigeration or air-conditioning system; and a method for neutralizing or removing an acid from the refrigeration or air-conditioning system. A sensor measuring the gap compensates the second electric field for physical changes in at least one of the tube and stem assemblies.
