20090155191 | Use of chlorhexidine in the prevention of root caries - Topical application of a solution of the antimicrobial chlorhexidine to teeth, particularly including exposed root surfaces, prevents the destruction of exposed cementum and associated exposed enamel at the cementum-enamel junction on tooth root surfaces (root caries) and the inflammation of the gingival tissue. In a method of use, a topical solution containing 10% (w/v) chlorhexidine, 20% (w/v) Sumatra benzoin, and 70% (w/v) ethanol is applied to the appropriate area of the tooth surface, followed immediately by application of a sealant which is a solution containing 29% (w/v) medical-grade polyurethane in 49% (w/v) acetone and 22% (w/v) ethyl acetate. Application of the chlorhexidine and sealant to the tooth cementum and gingival margin of “at risk” older adult patients has significantly reduced the prevalence and incidence of root caries and gingival inflammation. | 06-18-2009 |

20090249182 | NAMED ENTITY RECOGNITION METHODS AND APPARATUS - There is disclosed a method of recognising named entities in a text-containing document, represented by text document data. The received text document data comprising a plurality of tokens, one or more of the said plurality of tokens being part of a plurality of entities. The text document data is analysed using one or more tagging modules which are operable to determine token label data in respect of at least the tokens which are part of a plurality of entities, wherein the token label data output by the one or more tagging modules comprises data representative of the location of the token within each of a plurality of entities. The token label data representative of the location of the token within each of a plurality of entities is used to determine the beginning and end of the entities which have been identified in the text document data. A plurality of tagging modules may be employed, each of which is adapted to determine token label data representative of the location of a token within a different subset of the entities represented by the text document data, wherein the token label data determined by the plurality of tagging modules together is representative of the location of the said token with a plurality of entities. A single tagging module may be employed which determines a compound tag selected from a group of compound tags, the ground of compound tags including different tags in respect of a plurality of different combinations of the location of a respective token within a plurality of entities. | 10-01-2009 |
20110099184 | INFORMATION EXTRACTION APPARATUS AND METHODS - Automatic information extraction apparatus for extracting data for review by a human curator from digital representations of documents comprising natural language text, the automatic information extraction apparatus having a plurality of selectable operating modes in which the automatic information extraction apparatus is operable to extract different data for review by a human curator. In the different operating modes, the information extraction apparatus may extract data with a different balance between recall and precision. | 04-28-2011 |

20110216998 | OPTICAL SUB-ASSEMBLY - Described is a new wafer scale optical sub-assembly (OSA) and a method of production of such an OSA. Also described are optical wafers which form the central building block for the OSAs. The optical wafers comprise embedded optical features, which are positioned with reference to a single reference fiducial so as to avoid stacking of alignment errors. The embedded optical features may include refractive and/or waveguide optical channels. Cross-talk reduction features may also be provided between the embedded optical features. Embedding the optical features within the optical wafers protects the optical features from damage or contamination. The design of the optical features allows both transmit and receive functionality and arrays of optical devices to be packaged together. | 09-08-2011 |

20100089944 | REPLACEABLE CONCENTRATE/EXTRACT CARTRIDGE FOR A LIQUID CONCENTRATE/EXTRACT BEVERAGE DISPENSER - A concentrate/extract cartridge for a beverage dispenser adapted to dispense a liquid concentrate/extract and a diluent is provided. The cartridge includes a hollow body for containing liquid concentrate/extract and an aperture. A pumping device is connected to the hollow body for dispensing the liquid concentrate/extract from the hollow body through the aperture. A method for dispensing a liquid concentrate/extract from a beverage dispenser using a concentrate/extract cartridge is also provided in which the concentrate/extract does not come into contact with the dispenser. | 04-15-2010 |

20100161302 | Method For Predicting Petroleum Expulsion - A method for predicting petroleum production is provided. An exemplary embodiment of the method comprises computing a first approximation of an amount of generated petroleum that is retained with a complex organic product using a Threshold and a Maximum Retention value. The exemplary method also comprises revising the first approximation by approximating a process of chemical fractionation using at least one partition factor to create a revised approximation and predicting petroleum production based on the revised approximation. | 06-24-2010 |
20120325458 | Electrically Conductive Methods For In Situ Pyrolysis of Organic-Rich Rock Formations - A method and system for heating a subsurface formation using electrical resistance heating includes providing a wellbore which has a production portion that penetrates an interval of organic-rich rock within the subsurface formation. The method includes forming a fracture in the organic-rich rock along a plane that is generally parallel with the production portion of the wellbore. A first electrically conductive proppant is placed into the fracture. Second and third electrically conductive proppants are placed within the wellbore and in electrical communication with the first electrically conductive proppant. The second and third proppants are spaced apart, and have a bulk resistivity that is less than the bulk resistivity of the first proppant. The method then includes passing an electric current through the fracture such that heat is generated by electrical resistivity within the first proppant sufficient to pyrolyze at least a portion of the organic-rich rock into hydrocarbon fluids. | 12-27-2012 |
