    Abstract: A system for providing granular functionality called web services to commercial customers includes a web server configured to accept service requests from software application clients, functional implementations of the services, and a means of accounting for usage. The service grid architecture makes practical a reliable commercial provider of web services in the face of unreliable sources of functional implementations. This is accomplished through the commoditization of multiple implementation sources per service, standard forms for each service to which a plurality of sources is adapted, and a rules based approach to source selection per service call.

    Abstract: Hydrocarbon streams are heated uniformly and directly using one or more flameless oxidation burners. Flameless oxidation burners may control the temperature within a range of about 50° C. to reduce the tendency to coking due to localized “hot spots”. The hydrocarbon streams, which may be monomer streams, may pass cross-current (perpendicular) to burners having a longitudinal design or configuration, or may pass parallel to such burners.

    Abstract: An asphalt/aggregate composition having enhanced adhesion characteristics and its preparation. An asphalt base material is heated to a molten state in order to permit mixing of the asphalt with added components. A heavy metal soap is incorporated into the asphalt base material to enhance the adhesion of the asphalt base material with an aggregate component which is mixed with the asphalt base material to provide an asphalt/aggregate blend. The asphalt and aggregate can be blended together in a mixing chamber to provide a fluid asphalt/aggregate concrete which is then dispensed on a substrate surface or the asphalt base material and aggregate components can be separately applied to the substrate surface to provide the ultimate asphalt/aggregate concrete. The heavy metal soap is a C14-C18 heavy metal soap such as zinc stearate. Zinc oxide may also be added to the asphalt base material in an amount which is less than the amount of zinc stearate. The asphalt base material may be polymer-modified asphalt and may incorporate a crumb rubber component to provide a rubber-modified asphalt.

    Abstract: An apparatus for emitting electrons is provided. The apparatus includes a subsurface emitter having a sharp tip, a substrate including a base, and electrical continuity between the tip, the base, and an external circuit. This emitter structure may be used to form individual emitters or arrays of emitters. Also provided is a method of making electron emitters which is comprised of implanting energetic ions into a diamond lattice to form cones or other continuous regions of damaged diamond. These regions are more electrically conducting than the surrounding diamond lattice, and have locally sharp tips at or near the point of entry of the ion into the diamond. The tips may then also be additionally coated with a layer of a wide band-gap semiconductor. An electrically conducting material may also be placed in proximity to the tips to generate an electric field sufficient to extract electrons from the conducting tips into either the region above the surface, or into the wide band-gap semiconductor layer in contact with the tips. Electrical contact is made to the electrically conducting damage tracks and the electrical circuit may be completed with an electrically conducting material on the surface of the wide band-gap semiconductor or diamond, or in the ambient above the surface of the emitter. The surface of the wideband gap semiconductor or diamond may be chemically modified to enhance the emission of electrons from the surface.
