A distinct male cultivar of Salix sachalinensis\xd7S. In more particularity, the present invention relates to a method and apparatus that applies active combustion control technology to advanced propulsion devices and closed-loop fuel injection at sub-harmonic frequencies of the instability frequency of the combustor. A first planar element and a second planar element, of which at least one has electrical conductivity, are electrically connected to an externally exposed portion of the conductive wire material in such a manner that the first and second planar elements sandwich the exposed portion and are bonded so as to be in planar contact with each other. An agent manager to select a support agent having a skill set satisfying the identified skill set.
