  • Publication number: 20040183237
    Abstract: A container for product integrity and identification includes a bottle formed from a resin comprising polypropylene and a first set of dye stuffs present in the bottle in an amount sufficient to absorb visible and ultraviolet wavelengths which may cause product degradation. An ultraviolet blocking agent is present to absorb ultraviolet wavelengths which may cause product degradation. A second set of dyestuffs is present in the bottle in an amount sufficient to provide an identifying blue color of the bottle while enabling sufficient transmission of the light for visual inspection of the product contained in the bottle.

  • Publication number: 20040015976
    Abstract: A method allocates computing resources from a resource pool. Each job request includes attributes and a unique identifier. A digital signature is generated for each job request based on the combination of the attributes. The identifier is associated with the digital signature. Job requests having identical attributes are grouped together.

  • Publication number: 20030211259
    Abstract: A container for product integrity and identification includes a bottle formed from a resin comprising polyethylene terephthalate and a first set of dye stuffs present in the bottle in an amount sufficient to absorb visible and ultraviolet wavelengths which may cause product degradation. A second set of dyestuffs is present in the bottle in an amount sufficient to provide an identifying blue color of the bottle while enabling sufficient transmission of the light for visual inspection of the product contained in the bottle.

  • Publication number: 20030175979
    Abstract: A system and method for performing hydrogen/deuterium (H/D) exchange in an electrospray ionization (ESI) source is described. The system includes a liquid chromatograph-mass spectrometer (LC-MS), which is equipped with an ESI source that provides for introduction of a sheath liquid. The resulting system employs deuterated solvent, such as deuterium oxide, as the sheath liquid, which allows H/D exchange experiments to be performed on-line. This directly provides information for determining the number and position of exchangeable hydrogens, aiding in the elucidation of the structures of drug metabolites.

  • Patent number: 6063187
    Abstract: A method for the growth of diamond on a substrate combines an ECR (Electron cyclotron resonance) MPCVD (Microwave plasma chemical vapor deposition) method with a MPCVD method in one system. A two-step diamond growing method comprises firstly etching and nucleation performed by the ECR method and then diamond grown by the microwave plasma CVD method. Not only are high quality continuous polycrystalline diamond films on silicon wafer obtained but also heteroepitaxial growth has been achieved in the present invention. Auger electron spectroscopy (AES), scanning electron microscopy (SEM) and Raman spectroscopy have been used to characterize the structure and morphology of the synthesized diamond films.

  • Patent number: 5879450
    Abstract: A method and an apparatus have been developed to deposit heteroepitaxial beta-silicon carbide films on silicon using bias-assisted hot filament chemical vapor deposition (BA-HFCVD). The apparatus includes a graphite plate as the carbon source and the silicon substrate as the silicon source. Hydrogen was the only feeding gas to the system.
