    Notizen: Abstract Copper(II) oxide containing different amounts of sodium has been prepared. Thermo-analytical studies reveal differences in behaviour between sodium-incorporated samples and the control sample. A strong esr signal withg=2.1 is explained by assuming a square planar configuration around the Cu2+ ion. The spin concentration is found to vary linearly with the sodium content, each sodium decoupling the spins of 40 Cu2+ ions in CuO. The signal is found to be present even in a reduced sample. The origin of such species is explained on the basis of antiferromagnetic decoupling of spins.

    Notizen: Abstract A new type of roselle (Hibiscus sabdariffa L.) differing from other types in respect of certain morphological and physiological characters is described. Characteristic glandless sepal (gs) was monofactorial recessive to the normal glanded sepal (Gs). The normal ovoid (Co) shape of capsules was incompletely dominant over the round shape (co) in the new type. No linkage was observed between gs and co.

    Notizen: New experimental data indicate that mass flux in cocurrent gas-liquid flows may be determined by the use of Pitot tubes in conjunction with a local mixture density measurement technique. The data were taken over a wide range of flow regimes in a horizontal pipe and included separated patterns such as stratified and annular flows. Local mixture densities were obtained by a computer-assisted algebraic reconstruction technique that used chordal average densities measured by traversing gamma beam attenuation.The results extend the applicability of this mass flux measurement technique well beyond the relatively homogeneous, high-pressure, steam-water flow situations originally studied by Banerjee and Nguyen (1977).
