Abstract: An information retrieval system and method are presented. A template is retrieved from a template repository. The template repository stores a plurality of templates. Each of the plurality of templates includes a concept and a relationship from a knowledge model. The knowledge model defines a plurality of entities and interrelationships between one or more of the plurality of entities. The plurality of entities include concepts and instances. The template is transmitted to a client computer, and a statement is received from the client computer. The statement includes an instantiation of the template. A knowledge base is queried using the statement to generate a result listing identifying an item in the knowledge base. The knowledge base identifies a plurality of items. Each of the plurality of items is associated with at least one annotation identifying at one of the entities in the knowledge model.

Abstract: Oxidative dehydrogenation of light paraffins, such as ethane at moderate temperatures (<500° C.) to produce ethylene without the formation of side products such as acetic acid and/or other oxygenated hydrocarbons is achieved using tellurium-free, multimetallic catalysts possessing orthorhombic M1 phase and other crystalline structures that have an important role for obtaining high performance catalysts for the oxidative dehydrogenation of ethane to ethylene. Such catalysts are prepared using thermal and hydrothermal methods.

Abstract: An exemplary pullable drawer is arranged for removably protruding in a radial direction into an outer housing of a turbine, in order to make mechanical contact with an inner carrier being concentrically arranged within the outer housing. The pullable drawer has an essentially cylindrical body, which extends along a longitudinal drawer axis. A mechanical decoupling is provided, as the pullable drawer is divided along the longitudinal drawer axis into at least separate first and second parts. The first and second parts are coupled with each other by means of a releasable mechanical joint.

Abstract: The invention relates to a method based on mixing honey as a raw material and maltodextrin, in proportions of approximately 80% honey and approximately 20% maltodextrin. The mixture is stored in an inert atmosphere and is subjected to a vacuum drying process in order to obtain a pasty mass which is ground so as to obtain a grain-type product, corresponding to the desired final product. The natural sweetener obtained in used as a product to sweeten all types of drinks and food.

Abstract: A layered multimetallic mixed oxide (LMMO) is characterized by one or more diffraction peaks at 5<2?<15, preferably between 10<2?<15. The catalysts can be represented by the general formula: M1 M2 M3 O? wherein M1 is selected from the group of Ag, Au, Zn, Sn, Rh, Pd, Pt, Cu, Ni, Fe, Co, an alkaline metal, an alkaline earth metal, a rare earth metal, or mixtures thereof. M2 is selected from the group of Ti, Hf, Zr, Sn, Bi, Sb, V, Nb, Ta and P, or mixtures thereof. M3 is selected from the group of Mo, W and Cr, or mixtures thereof. ? depends on the amount and oxidation state or valence of the other components, also it depends on the starting materials, preparation method and the activation process, and where the catalyst exhibits at least one X-ray diffraction peak between 5<2?<15.
