    Description / Table of Contents: Zusammenfassung Die vom Strahlungsaufzeichnungsnetz der Geophysikalischen Hochschule Genua aufgenommenen monatlichen Mittelwerte der Global- und Himmelsstrahlung werden untersucht, wobei charakteristische Elemente des Sonnenklimas von vier typischen Stationen in NW-Italien deduziert werden. Die Himmelsstrahlung wird für diejenigen Stationen, wo diese nicht aufgenommen wird, durch Anwendung von Korrelationen zwischen Meßwerten und einem Klarheitsparameter bzw. einer Sonnenscheinzahl geschätzt. Außerdem werden örtliche Faktoren diskutiert, die die Schwächung der Globalstrahlung unter wolkenlosem Himmel bestimmen.
    Notes: Summary An analysis is made of the monthly mean global and diffuse irradiance values recorded by the Genoa University Geophysical Institute radiation network to derive characteristic elements of the solar climate in four typical NW Italy locations. Diffuse irradiation was estimated for the stations where diffuse irradiation data were not recorded, by using correlations between measured data with clearness parameter and sunshine index. Local factors which affect the attenuation of global irradiance under cloudless skies are discussed.

    Notes: Rats with skin-wounds surgically created on their backs were exposed immediately after surgery and every 12 h thereafter to pulsed, extremely-low-frequency magnetic fields. The shape of the pulse was a positive triangle (50 Hz, 8 mT peak). The rate of healing of skin wounds was evaluated macroscopically and by light and electron microscopy at 6, 12, 21, and 42 days after the operation. A significant increase in the rate of wound contraction was found in rats treated with magnetic fields. Forty-two days after surgery all treated animals show fully closed wounds, while control rats at the same time intervals still lacked a final 6% of the wound surface to be covered. Treated rats showed earlier cellular organization, collagen formation and maturation, and a very early appearance of newly formed vascular network.
