Abstract: Method and apparatus for igniting an air/fuel spray (26) comprised of fuel droplets. The apparatus includes a coherent optical source (12) for introducing at least one pulse of coherent radiation into the air/fuel spray. The pulse generates free electrons and initiates a development of a plasma within the air/fuel spray. The coherent source maintains the pulse of coherent radiation and pumps the developing plasma to higher energies. The pulse is terminated at a time after the plasma has reached a predetermined energy and before ignition of the air/fuel spray. The non-linear ignition system of the invention employs a gas/vapor interface region at a fuel droplet surface and an electric field that extends from and exists outside of a fuel droplet. Free electrons are accelerated to higher energies by the electric field surrounding the fuel droplet. The accelerated electrons initiate a breakdown near adjacent fuel droplets and the liberation of further free electrons.

Abstract: There is disclosed structured lipid containing either a gamma-linolenic acid or a dihomogamma-linolenic acid residue, together with an n-3 fatty acid residue and a medium chain fatty acid residue on the same glycerol backbone. This structured lipid is particularly well adapted to the treatment of disease or stress states. The gamma-linolenic or dihomogamma-linolenic acid residues modify the prostanoid synthesis pathway, reducing the level of series "2" prostanoids and elevating the levels of series "1" and "3" prostanoids. The n-3 fatty acid residue enhances the level of series "1" prostanoids as well as increases the production of series "3" prostanoids. The medium chain fatty acid residues enhances the absorption of the structured lipid. There is also disclosed enteral and parenteral diets as well as nutritional supplements containing the structured lipids of the invention.

Abstract: New strains of microorganisms which posses the dual capabilities for growth on surfactants and degradation of polychlorinated biphenyls are used in combination with soil washing for PCB bioremediation. Soil to be treated is washed with a surfactant to solubilize the generally hydrophobic contaminants. The surfactant solution is then treated in a bioreactor with the microorganisms. As the surfactant is degraded, the residual desolubilized contaminants are adsorbed onto an inert substrate, which is removed from the effluent and can be recycled to the bioreactor.

Abstract: A method of synthesis of the four optically active stereoisomers of calanolide A and B which produces the compounds in high yields and in a high degree of purity.
