  • Publication number: 20150344858
    Abstract: The present compositions and methods relate to an endo-beta-mannanase cloned from Bacillus lentus, polynucleotides encoding the endo-beta-mannanase, and methods of use thereof. Formulations containing the endo-beta-mannanase are highly suitable for use as detergents.

  • Patent number: 6304265
    Abstract: The present invention directed to a method and apparatus for distinguishing between front facing and back facing polygons in a computer graphics environment. The method determines whether the polygon is a triangle, a quadrilateral, or a polygon with more than four vertices. Then the method computes the area of the polygon using a first formula, if the determining step determines the polygon to be a triangle. If the determining step determines the polygon to be a quadrilateral, then the method computes the area of the polygon using a second formula. Finally, if the determining step determines the polygon to be a polygon with more than four vertices, then the method computes the area of the polygon using a third formula. Each of the formulas—the first formula, the second formula, and the third formula—differ from one another.

  • Patent number: 6171825
    Abstract: Recombinant Factor VIII can be produced in relatively large quantities on a continuous basis from mammalian cells in the absence of any animal-derived proteins such as albumin by culturing the cells in a protein free medium supplemented with polyol copolymers, preferably in the presence of trace metals such as copper. In very preferred embodiments, the medium includes a polyglycol known as Pluronic F-68, copper sulfate, ferrous sulfate/EDTA complex, and salts of trace metals such as manganese, molybdenum, silicon, lithium and chromium. With an alternative medium which included trace copper ions alone (without polyol copolymers) we were also able to enhance the productivity of Factor VIII in recombinant cells such as BHK cells that are genetically engineered to express Factor VIII.

  • Patent number: 6097395
    Abstract: A computer graphics system includes a lighting system that performs lighting efficiently by selecting dynamically the lighting space in which lighting calculations are to be performed to thereby minimize resources required to be expended to perform lighting. A particular preferred lighting coordinate system is then selected, based upon particular criteria, and the light source information is transformed to the selected coordinate system (if necessary) where lighting is performed. The dynamic selection can take many objective indicia into account, such as whether functions other than lighting must be performed in either of the coordinate systems, whether transformation of the lighting information is possible and the relative efficiencies of performing lighting in one coordinate system verses the other coordinate system.
