  • Patent number: 11739312
    Abstract: In one aspect, the invention is directed to polypeptides having an amylase and/or glucoamylase activity, polynucleotides encoding the polypeptides, and methods for making and using these polynucleotides and polypeptides. In one aspect, the polypeptides of the invention can be used as amylases, for example, alpha amylases, to catalyze the hydrolysis of polysaccharide, oligosaccharide or starch into sugars. In one aspect, the invention provides delayed release compositions comprising an desired ingredient coated by a latex polymer coating. In alternative embodiments, enzymes are used to make biofuels, e.g., ethanol, butanol, propanol, or a gasoline-ethanol mix, including a bioethanol, biopropanol, biobutanol, or a biodiesel, or for any form of fuel or biomass processing.

  • Publication number: 20030220815
    Abstract: A method of determining and displaying a plurality of tasks to a user in a healthcare environment is provide that includes receiving an order associated with a patient, determining a type of the order, and identifying a task template associated with the order. The method further includes determining if an overriding template exists for the order, linking one of the task template or the overriding template to the order, and associating one or more task records with the linked template. The method also includes determining a plurality of tasks corresponding to the task records, adding the plurality of tasks to a work list, filtering the plurality of tasks on the work list for a patient list based on an attribute of the user and displaying the filtered list to the user.

  • Publication number: 20030121095
    Abstract: A bathing chair is provided that swivels on a fixed base and includes a leg support assembly. The combination of the leg support and the swiveling action of the chair allows a disabled or handicapped bather to comfortably enter and/or exit a bathtub or a shower stall without the aid of another person. The leg support also allows the legs of the bather to clear obstacles, such as the ledge of a bathtub or the lip of a shower stall, without the aid of another person. The bathing chair also includes a single support assembly that is capable of supporting the bathing chair and a bather without the need for any additional support structures. The need for only a single support assembly to adequately support the chair provides a bathing chair that is sturdy, lightweight and simple to install.
