    Notes: Summary According to the author the reason of the subsistence of the 11 years' sunspot cycle is to be found in the conjunction of the planets. As a result of the investigations it has been stated that from among the nine planets the joint tidal effect of Venus-Jupiter-Earth is a decisive factor in the variations of sunspot activity. The above three planets are every 10.4 years and 12.0 years respectively, in a close conjunction. The mean value (11.2 years) is in an almost full accordance with the average cycle-period. The fluctuations of the period of the cycle come from the fact that the planets' getting into approximately one line takes a different time within each cycle. This time delay is the cause of the stronger or weaker sunspot activity, and of the shorter or longer cycles.

    Heteroepitaxial growth of ZnS on GaP (1969)
    Springer
    Journal of materials science 4 (1969), S. 699-703 
    Details
    ISSN: 1573-4803

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Epitaxial layers of ZnS were grown on GaP single crystals by a chemical transport reaction. The growth process and the heterostructures obtained were investigated by X-ray diffraction and optical microscopy. It was found that the epitaxial overgrowth is polarity dependent. The formation of a transition layer at the interface between the ZnS and GaP was observed.
