  • Publication number: 20120329112
    Abstract: The present invention provides genetically modified strains of microorganisms that display enhanced tolerance to stress and/or inhibitors such as sodium acetate and vanillin. The enhanced tolerance can be achieved by increasing the expression of a protein of the Sm-like superfamily such as a bacterial Hfq protein and a fungal Sm or Lsm protein. Further, the present invention provides methods of producing alcohol from biomass materials by using the genetically modified microorganisms of the present invention.

  • Patent number: 8227653
    Abstract: The invention relates to olefin oligomerization methods and methods for reducing/inhibiting fouling in olefin oligomerization reactions comprising: contacting, in an oligomerization reactor (e.g., under oligomerization conditions), an alpha-olefin feed, a catalyst having an olefin selectivity of at least 90 mol % to a desired oligomerization product, a polymer anti-foulant, and optionally a diluent; selectively producing an effluent comprising the desired oligomerization product, unreacted olefin, and alpha-olefin-based polymer byproduct that causes fouling. The amount of polymer anti-foulant can be chosen to limit fouling to ?20 g/kg desired oligomerization product, to remediate ?3 grams fouled polymer/kg desired oligomerization product, and/or to reduce/inhibit polymer fouling by ?10% over a selective oligomerization with substantially no added polymer anti-foulant. Advantageously, desired oligomerization product so obtained can also be polymerized/copolymerized with an alpha-olefin such as ethylene.

  • Patent number: 8160666
    Abstract: A system for determining the concentration of an analyte in at least one body fluid in body tissue comprises an infrared light source, a body tissue interface, a detector, and a central processing unit. The body tissue interface is adapted to contact body tissue and to deliver light from the infrared light source to the contacted body tissue. The detector is adapted to receive spectral information corresponding to infrared light transmitted through the portion of body tissue being analyzed and to convert the received spectral information into an electrical signal indicative of the received spectral information. The central processing unit is adapted to compare the electrical signal to an algorithm built upon correlation with the analyte in body fluid, the algorithm adapted to convert the received spectral information into the concentration of the analyte in at least one body fluid.

  • Publication number: 20100291647
    Abstract: The present invention provides isolated or genetically modified strains of microorganisms that display enhanced resistance to acetate as a result of increased expression of a sodium proton antiporter. The present invention also provides methods for producing such microbial strains, as well as related promoter sequences and expression vectors. Further, the present invention provides methods of producing alcohol from biomass materials by using microorganisms with enhanced resistance to acetate.

  • Patent number: 7720863
    Abstract: A method, system and computer program are useful for enforcement of business application security rules in connection with applications external to the business application. To support secured access to data stored in a database system managed by a business application, a rule directed from the business application to a database system specifying security criteria for access to the data is received. A database view to select a subset of the data in accordance with the security criteria is then created, and a representation of the database view is stored in the database system to support the secured access to the subset of the data in connection with a query from the application external to the business application. When the query is then received, the user is identified along with a specification of the database view to return the subset of the data authorized by the security criteria for that user.

  • Patent number: 6550608
    Abstract: A carton feeding system for feeding cartons into a packaging machine is disclosed. The carton feeding system includes a frame in which a carton feeder is rotatably mounted and a carton guide assembly. The carton guide assembly includes a pair of spaced guide tracks along which guide chains are moved to engage and urge the cartons along the carton feeding system toward a drop point overlying a series of products passing therebeneath. A pair of spaced chute plates receive and support the ends of the cartons as the cartons are released by the carton feeder and are urged by the guide chains along a feed path toward the drop point and engagement with a series of products passing through the product-packaging machine.

  • Patent number: 6466929
    Abstract: A data processing and analysis system, and a method of using the same, for discovering implicit relationships in data. The method is executed in a computer system capable of receiving input data comprised of expert knowledge, empirical data, and user-defined constraints for any application domain. The system and method provide any pre-processing the input data may require, and perform feature selection and extraction on the input data. Further, the system and method generate a graphical representation of the implicit relationships in the input data, indicating relationships between both class variables and feature variables. Also generated is a classifier that provides a semantic and statistical justification of its classification results which further provides: statistical relevancy of the data set, including an indication of the undersampled regions of the data space; a data analysis specific to a desired level of confidence; and a sound decision theoretical foundation for classification thresholding.

  • Patent number: 6140839
    Abstract: A computational field programable architecture targeted for compute intensive applications. The architecture is hierarchical and includes, for implementation of data path circuits, clusters of programable logic blocks that are designed to provide area-efficient realization of common arithmetic structures such as adders, subtracters and multipliers. The architecture includes a LUTb cluster for implementing the control part of a circuit. The programable logic blocks each include a stack of programable bit-slice logic elements each having 2 data inputs and a single data output, and a 1-bit full adder circuit. The bit slice logic elements allow bit-wise logic operations to be carried out and the programable logic blocks also include comparator logic to enable comparison operations to be performed. The bit slice logic elements each include a DFF at their output, and the DFFs in a programable logic blocks can be combined to form a register.
