Selective as well as waste forming active centers were defined for MoVNbTeO and MoVTaTeO catalysts in the ammoxidation of propane to acrylonitrile and all catalytic functionalities were assigned to specific elements at the respective active centers. Symbiosis between M1 and M2 phases of these catalysts was observed, with phase cooperation being more extensive in the Nb than Ta containing compositi

Popular Abstract in Swedish Syftet med denna avhandling är att studera hur sagor kan förändras när de förflyttas från en miljö till en annan. Flytten kan ske på flera plan; från muntligt berättande till skriftlig text, från lantligt proletariat till urban borgerlighet. Utgångspunkt har varit sagoinsamlaren och sagoförfattarens Eva Wigström (1832-1901) som på 1880-talet vandrade Skåne runt för att The purpose of this thesis is to study how fairy tales can change when they are removed from one set of surroundings to another. This movement can occur on several levels; from an orally spoken to a written text, from a rural proletariat to an urban bourgeoisie. The point of departure has been the fairy tale collector and fairy tale writer Eva Wigström (1832-1901) who in the 1880s wandered through

The presence of α-l-fucosyltransferases in human serum of different ABO, secretor and Lewis blood-group phenotypes was investigated with guanosine diphosphate fucose as the sugar donor and low-molecular-weight oligosaccharides, or a macromolecular glycoprotein, as acceptors. In contrast to the α-2-l-fucosyltransferases in human milk, submaxillary glands and stomach mucosa that occur only in ABH se

Thin magnesium-nickel films grown on Mo( 110) under ultra-high vacuum conditions were hydrogenated with atomic H and studied by high-resolution core-level photoelectron spectroscopy ( PES) and thermal desorption spectroscopy (TDS). We show spectroscopic evidence for reversible hydrogen storage and clear evidence that no Mg segregation or desorption occurs when hydrogen is desorbed from the film. D

In an open, randomized prospective clinical trial the analgesic effect of indomethacin and ketobemidon was compared in 67 patients with acute cholecystitis (28 received 5 mg ketobemidon and 39 received 50 mg indomethacin). Both drugs showed a good and significant pain relief, exhibiting no significant difference in the analgesic effect and no serious adverse reactions. It was concluded that indome

The title compound, lithium potassium dialuminium diger-manium octaoxide dihydrate, (K,Li)-(Al,Ge)-GIS (GIS is gismondine), is the result of a 50% Li+ exchange into the K-(Al,Ge)- GIS structure. The (K,Li)-(Al,Ge)-GIS structure was determined from a 4 x 4 x 2 m m octahedral single crystal at the ESRF synchrotron X-ray source. The ion exchange results in a symmetry transformation from I2/a for K-(A

A solvent-free microextraction technique based on liquid-gas-liquid microextraction was investigated for the extraction and preconcentration of 2,4-di-tert-butyl phenol from aqueous samples. In this study 16 mu L NaOH 1 M as acceptor phase was introduced in the lumen of a polypropylene hollow fiber, with one of its ends heat-sealed. A small piece (about 2 cm) of metallic wire was used to seal the

Context: Ghrelin is a novel hormone produced mainly in the gastric body. Hitherto, mapping studies of ghrelin cells covering the entire gastrointestinal (GI) tract in humans have been lacking. Furthermore, the phenotype of extragastric ghrelin cells is not known. Objective: The objective of the study was to perform a detailed mapping with specimens from all parts of the GI tract, and colocalizatio

Air flow rate through filters and face masks is one important determinant of the final protection factor of a respiratory protective device in use. Respiratory minute volumes and instantaneous breath flow rates were measured in eight subjects during treadmill work using three types of filtering respirators and one control breathing mask. Work comprised five consecutive bouts of walking at 5 km/h w

Effects of core-level degeneracies on X-ray photoemission spectra are considered theoretically and computationally. Processes within each degenerate sub-level manifold are treated by a leading-order cumulant approximation, and processes which connect spin-orbit or crystal-field split levels to leading order in the core-electron self-energy. The cumulant approximation is consistent with earlier asy
