The rich structure of the set of dyadic PFW’s has been presented in [6]. As mentioned in [6, Remark 3.7], the subclass of the so called non-W0-frames with various levels of W0-linear independence (denoted by P0,+ in [6]) needs extra attention. The recent observation in [4] on W0-Schauder bases enables us to properly restructure this subclass (P0,+) and to show that it contains a wealth of examp...

Bismuth tungstate has attracted great attention as a new photocatalyst working under visible irradiation. In this paper, we demonstrate a facile hydrothermal route for controllable synthesis of novel Bi(2)WO(6) hierarchical hollow spheres with an ultrahigh specific surface area in the presence of poly(vinyl pyrrolidone) at a proper C(2)H(5)OH/CH(3)COOH/H(2)O volume ratio. The obtained products ...

BACKGROUND End-expiratory lung volume measurement by the nitrogen washin-washout technique (EELVWI-WO) may help titrating positive end-expiratory pressure (PEEP) during acute respiratory distress syndrome (ARDS). Validation of this technique has been previously performed using computed tomography (EELVCT), but at mild PEEP levels, and relatively low fraction of inspired oxygen (FiO2), which may...

The recent progress in application of nanostructures in electrochromic materials and devices is reviewed. ZnO nanowire array modified by viologen and WO₃, crystalline WO₃ nanoparticles and nanorods, mesoporous WO₃ and TiO₂, poly(3,4-ethylenedioxythiophene) nanotubes, Prussian blue nanoinks and nanostructures in switchable mirrors are reviewed. The electrochromic properties were significantly en...

Tungstated zirconia is a robust solid acid catalyst for light alkane (C(4)-C(8)) isomerization. Several structural models for catalytically active sites have been proposed, but the topic remains controversial, partly because of the absence of direct structural imaging information on the various supported WO(x) species. High-angle annular dark-field imaging of WO(3)/ZrO(2) catalysts in an aberra...


 Das Einzige, das Bestand hat, ist die Veränderung. Dieser Prozess war noch nie so schnell wie jetzt. Unsere Welt verändert sich im Minutentakt und macht es uns immer schwerer, einen Anker für unser Leben zu setzen. Darum umso wichtiger, den aktuellen Herausforderungen stellen, Lösungsansätze suchen in eigene Tun implementieren. Mit Techniken der Wo-bist-du-Frage oder Auseinandersetzung m...

HE locus of Woolly is in chromosome 2 of the tomato, Lycopersicon escuZentum, in which the basic chromosome number is 12. Three alleles, in addition to the normal non-Woolly allele, WO+, are known. WO and Wov are dominant and lethal when homozygous, and WO"' is partially dominant and viable when homozygous (RICK and BUTLER 1956). Woolly plants have thicker, longer trichomes than the normal and ...
