Abstract: The invention relates to an apparatus for separating hydrogen from a gas mixture, comprising a vessel which defines an inlet collection space for the gas mixture and an offtake collection space for hydrogen, where the inlet collection space is separated from the offtake collection space by means of a hydrogen-permeable membrane. The invention is also directed to a process for producing an apparatus for separating hydrogen from a gas mixture, which comprises a hydrogen-permeable membrane, a gas mixture inlet, a hydrogen offtake and a residual gas outlet.

Abstract: An aspect of generating a product model includes extracting from source code of an application system at least one transaction definition associated with the source code. Each transaction definition describes a transaction in a product implemented by the source code. An aspect also includes dividing the transaction definition into one or more product categories, and obtaining a product component associated with one of the product categories from the source code so as to generate the product model. The product component includes at least one product parameter associated with the product category, and the product model includes an association relationship between the product category and the at least one product parameter.

Abstract: There is disclosed an ultrahigh strength and ultrahigh toughness oil casing pipe, comprising the following chemical elements in mass percentages: C: 0.12-0.18%; Si: 0.1-0.4%; Mn: 1.1-1.6%; Cr: 0.1-0.4%; Mo: 0.2-0.5%; Nb: 0.02-0.04%; Ti: 0.02-0.05%; B: 0.0015-0.005%; Al: 0.01-0.05%; Ca: 0.0005-0.005%; N?0.008%; with the proviso of 0<(Ti—3.4N)?0.02%, Ti/B?10; and the balance of Fe and other unavoidable impurities. The strength of the oil casing pipe can be equal to or higher than 150 ksi steel grade, and the zero degree lateral Charpy impact work is not less than 10% of the yield strength of the 150 ksi steel grade.

Abstract: Embodiments of the present disclosure are related to a nail polish kit including a stem, a plurality of interchangeable applicator elements where one applicator element is configured to connect to the stem at a time, an overcap that is configured to connect to the stem and a tray that holds the stem, the overcap and the plurality of interchangeable applicator elements. The distal end of the stem includes a threaded component that corresponds to a threaded component of a proximal end of the applicator element, that can be coupled and decoupled and each of the plurality of interchangeable applicator elements have a different type of application mechanism from each of the other plurality of application elements.

Abstract: The present invention relates to systems and methods for biomedical drug research, addressing major molecular, cell biological and biochemical information management issues within drug discovery and basic biomedical science. The invention allows scientists to enter biological, chemical, and/or molecular data into a central database, analyze the data entries according to entry attributes, and graphically view the results. A group of web-enabled researchers can enter, share and analyze molecular and cellular data and information from the resources using standardized vocabularies and ontologies. This application describes in detail components of the databasing system, including but not limited to annotation modules, reference managers, advanced search algorithms, ontology browsers, molecular network builders, and text processing scripts.
