Abstract: A computational method for performing a data transformation process for use in Engineering Asset Management on an industrial scale is described, The method and associated integration environment includes a transformation engine or module to map model elements and data items from a first information system, for example a procurement and construction database that records the thousands of individual components used to construct an industrial site, to a second information system. Such as an operation and maintenance database. The method uses a model transformation user interface using hierarchically linked layers to allow users to create, view and modify the transformation specification, as well as element terms and element relationships which define a transformation specification, without having to write the underlying code that performs the transformation.

Abstract: The presently claimed invention relates to a method for concentrating a beta-glucan comprising at least the following steps: (a1) contacting an aqueous beta-glucan solution having a concentration [c1] with at least one precipitating agent p1 to obtain a precipitated beta-glucan in a solvent mixture comprising water and the at least one precipitating agent p1; (b1) separating the precipitated beta-glucan from the solvent mixture comprising water and the at least one precipitating agent p1 to obtain a precipitated beta-glucan having a concentration [c2]; and (c1) applying force to the precipitated beta-glucan of (b1) to obtain a precipitated beta-glucan having a concentration [c3].

Abstract: The invention relates to a process for the extractive removal of phenols, alcohols, amines, phoshines, hydroxylamines, hydrazines, oximes, imines, water, carboxylic acids, amino acids, hydroxamic acids, sulfinic acids, sulfonic acids, peroxycarboxylic acids, phosphonous acids, phosphinous acids, phosphonic acids, phosphinic acids or phosphoric acids from aprotic solvents by means of ionic liquids of the formula [K]n+[A]n?, where n, [K]+ and An? are defined as in the description.

Abstract: The invention relates to a method for producing 2-keto-L-gulonic acid-C4–C10 alkyl ester by esterifying 2-keto-L-gulonic acid (KGS) with an unsaturated, branched or unbranched C4–C10 alcohol. The inventive method is characterized by the fact that an aqueous KGS solution is reacted with a C4–C10 alcohol up to an esterification degree of 20 to 70 percent in a pre-esterification process carried out under acidic catalysis conditions; and the obtained product is dehydrogenated with an unsaturated, branched or unbranched C4–C10 alcohol in a continuous rectification device, whereby the esterification reaction continues, n-butanol preferably being used as the alkyl alcohol. In a preferred embodiment, the aqueous KGS solution is concentrated up to or beyond the limit of solubility prior to the esterification process, preferably by catalyzing a homogeneous or heterogeneous catalyst, especially sulfonic acid, at temperatures of 50 to 120° C.
