    Description / Table of Contents: Zusammenfassung Registrierungen der Chloridteilchenkonzentration in der bodennahen Luft an der Westküste von Dänemark während einer Dauer von fünf Monaten zeigen eine sehr klare Abhängigkeit vom Wetterablauf. Dabei werden hohe Konzentrationen bei stürmischen Westwetterlagen mit Vorbeizug von Tiefdruckgebieten, niedrige bei Ostwetterlagen mit hohem Luftdruck über Skandinavien gefunden. Dieser Befund zeigt klar, dass grosse Mengen von Chloridteilchen wohl ausschliesslich in den Starkwindfeldern der Zyklonen über dem Meere durch Zerstäuben von Gischt erzeugt werden. Einige Ergebnisse über Grössenverteilungsbestimmungen werden mitgeteilt.
    Notes: Summary For a periode of five months, the chloride particle concentrations in the air near the ground were measured at the west-coast of Denmark. The results show clearly, that high concentrations are connected with west wind, especially with passages of cyclones over Denmark or Skagerrak, low concentrations with east wind and anticyclones over Scandinavia. This lead us to the conclusion, that high concentrations of chloride particles are generated in the storm-areas of deep cyclones over the sea.

    Simultaneous vertical profiles of condensation nuclei and ozone in the lower troposphere (1974)
    Springer
    Pure and applied geophysics 112 (1974), S. 887-899 
    Details
    ISSN: 1420-9136

    Topics: Geosciences , Physics
    Notes: Summary Eight vertical profiles compiled from simultaneous measurements of Aitken nuclei and ozone concentrations over Germany in different weather conditions are discussed. The position and shape of the profiles is shown to depend on the prevailing weather conditions and the type of air masses. High aerosol concentrations in smoke plumes correlate in some cases with lower ozone concentrations, indicating that ozone in such cases is destroyed in the presence of high concentrations of pollutants such as aerosols and gases. A layered structure in the profiles was found only in association with temperature inversions and where the air above 2 km was subsiding, and was not found in convective parts of the troposphere.

    Description / Table of Contents: Zusammenfassung Die Verweilzeitverteilung des Gases in mehrstufigen Wirbelschichtanlagen wurde untersucht. Als Spurengas diente Helium. Bei den Versuchen wurden die Partikelkonzentration, die Zahl der Wirbelschichtstufen und deren bezogene Höhe verändert. Ein Vergleich mit den Ergebnissen von Untersuchungen an absatzweise betriebenen Wirbelschichtanlagen ergaben, daß bei kontinuierlichem Durchfluß der fluiden und der partikelförmigen Phase durch die mehrstufige Anlage das Gas die engere Verweilzeitverteilung aufweist und daher zu günstigeren Betriebsbedingungen beiträgt.
    Notes: Abstract The residence time distribution of the gas in multistage fluidised beds is studied, using Helium as tracer, for different conditions of the solids concentration, the number of stages and the height-to-diameter ratio of the stage. The results are compared with that of batch fluidisation with and without baffles and it is found that continuous fluidisation gives better flow characteristics of the gas and possesses a wider range of operation than batch fluidisation.

    Strong impact of the electron-photon matrix element on angle-resolved photoelectron spectra of Sr 2 CuO 2 Cl 2 (2001)

    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract: In recent years insight has been gained into the electronic structure of layered cuprates using angle-resolved photoelectron spectroscopy. In many of these studies it is assumed that the electron-photon matrix element follows the trends set by the atomic photoionization cross sections and does not influence lineshape, dispersion and the k-dependence of the spectral intensity. In this study using Sr2CuO2Cl2 as an example it will be shown that the electron-photon matrix element can have a strong impact on both strength and shape of a feature in an angle-resolved photoelectron spectrum of a layered cuprate which can strongly affect information on character and the momentum-dependence of the energy and spectral weight of a state deduced from the spectra. The results of this study put an emphasis on the need to employ the whole parameter range of the ARPES method to get reliable information on the spectral function of cuprates for which purpose synchrotron radiation is an uniquely suited tool.

    Nasal Epithelial Permeation of Thymotrinan (TP3) Versus Thymocartin (TP4): Competitive Metabolism and Self-Enhancement (2000)

    Notes: Abstract Purpose. To investigate concentration dependent permeabilities andmetabolism kinetics of thymotrinan (TP3) versus thymocartin (TP4)in nasal epithelium in vitro. Methods. Excised bovine nasal mucosa was used as an in vitro model.Permeabilities were studied in a diffusion chamber, metabolism kineticsin a reflection kinetics set-up. Studies were performed at various TP3and TP4 concentrations. The 3H-mannitol flux was measured to monitorjunctional permeability. Potential Ca2+-complexation was investigatedusing a Ca2+-selective electrode. Results. Permeability of TP3 was negligible at 0.1 and 0.2 mM andincreased drastically above 0.4 mM up to ∼2 × 10−5 cm s−1. In thepresence of 2 mM TP4 the TP3 permeabilites were significantly above(∼4 × 10−5 cm s−1) the level of TP3 without TP4, and TP3 metabolismwas totally inhibited. TP3 and TP4 showed a significant concentrationdependent effect on the permeability of 3H-mannitol. Ahyperosmolarity effect of the peptide solutions was excluded. Transepithelialelectrical resistance (TEER; ∼30 Ω cm2) was unchanged by either TP3 orTP4. At 1 mM TP3 the mucosal-to-serosal permeability was four timeshigher than serosal-to-mucosal, indicating enzyme polarization. Inreflection kinetics studies, TP3 degradation was slightly higher on themucosal than on the serosal side. TP3 and TP4 followed the samenon-linear metabolism kinetics. Conclusions. Increase in permeability at high TP concentrationsinvolves competitive enzyme saturation combined with self-enhancedparacellular permeation.
