    Notes: [Auszug] ALTHOUGH it is known that specimens of hexuronic acid (since renamed ascorbic acid) possess antiscorbutic properties, it has remained to show whether this activity was an inherent property of the pure substance itself or ascribable to some associated impurity. Experiments to test the point have ...

    Description / Table of Contents: Zusammenfassung  Mit Hilfe der Laplace-Transformation wird eine exakte Lösung für die Strömung entlang einer plötzlich in Bewegung gesetzten, unendlich ausgedehnten, vertikalen Platte hergeleitet, wobei deren Oberfläche einen aus der Umgebung gespeisten konstanten Massenstrom aufnehmen soll. Geschwindigkeits-, Temperatur- und Konzentrationsprofile sind graphisch dargestellt, ebenso Reibungsbeiwerte und Sherwood-Zahlen. Der Einfluß verschiedener Parameter, wie Grashof-Zahl, modifizierte Grashof-Zahl, Prandtl-Zahl und Schmidt-Zahl wird diskutiert.
    Notes: Abstract  An exact solution to the problem of flow past an impulsively started infinite vertical plate in the presence of a foreign mass and constant mass flux at the plate is presented by the Laplace-transform technique. The velocity, the temperature and the concentration profiles are shown on graphs. The skin-friction and the Sherwood number are also shown on graphs. The effects of different parameters like G (the Grashof number), Gc (the modified Grashof number), Pr (the Prandtl number) and Sc (the Schmidt number) are discussed.

    Notes: Abstract A finite-difference solution to the flow past an impulsively started infinite vertical plate is derived by assuming 1) presence of species concentration like water vapour, CO2 etc. and 2) constant heat flux at the plate. The velocity and the temperature profiles, the skin-friction and the rate of heat transfer are shown graphically. The effects of the modified Grashof number, Gm, the Eckert number E, the Schmidt number Sc on the flow of air are discussed.

    Theory of nuclear quadrupole interactions in aluminum and copper metals in presence of muon (1986)
    Springer
    Hyperfine interactions 31 (1986), S. 69-74

    Notes: Abstract The electric field gradients at27Al and63Cu nuclei which are nearest neighbors to the muon in the face-centered cubic metals aluminum and copper, with muon at an octahedral interstitial site, are studied. The electron density fluctuations needed for the evaluation of the electronic, or valence, contributions to field gradients are taken from earlier investigations involving the spherical solid approximation. The enhancement factors a that have to be applied to the electric field-gradients obtained from these approximations, due to the departures of the electronic wave-functions from plane-wave character, and the incorporation of antishielding effects, have been obtained for both APW and OPW approaches to the conduction electron wave-functions and good agreement is found between the results by the two approaches. Size effects due to the lattice distortion associated with the presence of the muon are included through actual point ion summations using available calculated displacements of the ions surrounding the muon. The valence contributions are the dominant ones but the size effect contributions are also significant. The net field-gradient obtained for the27Al site is significantly smaller than experiment while that for63Cu is substantially larger than experiment. Possible sources that could lead to better agreement with experiment are discussed and it is concluded that major improvement is needed in the valence effect contributions in both metals.
