    Notes: Abstract A new frequency-magnitude relationship which takes into account the existence of an upper limit for the magnitude, and generalizes the previous ones, is proposed. The formula obtained has been applied to the Western Alps area activity during the period 1950–75, and in addition to the limiting magnitude value, some useful results for the calculation of the seismic risk have been deduced using Gumbel's theory. The use of the present relationship appears to be necessary when long periods of time are considered, while for the study of the annual probabilities the Gutenberg and Richter formula is shown to be sufficiently accurate.

    Description / Table of Contents: Zusammenfassung Es wurde die Globalstrahlung in GeU und GeMCap analysiert, womit es im Zusammenhang mit den thermo-pluviometrischen Angaben ermöglicht wurde, die klimatischen Charakteristiken eines am Meere gelegten Ortes (GeU) und eines auf den Appenninen gelegenen Ortes (GeMCap) zu beschreiben. Auf GeMCap weisen diese klimatischen Faktoren im Winter-Herbst einen kontinental-maritimen Charakter und im Frühling-Sommer einen streng kontinentalen Charakter auf.
    Notes: Summary It has been analysed the global solar radiation at GeU and GeMCap, that in connection with the thermo-pluviometric data has also allowed to outline the climatic characteristics of a coastal site (GeU) and of a site on Apennin ridge (GeMCap). At GeMCap these climatic parameters show a continental-maritime behaviour in winter-autumn and strictly continental feature in the remaining half year.

    Description / Table of Contents: Zusammenfassung Anhand der in 20 Jahren durchgeführten Untersuchungen über die auf dem Berg Capellino (Genoa, Italien) gesammelten Winddaten wird eine eingehende Analyse durchgeführt, aus der sich ergeben hat, daß die Windenergie eine aussichtsreiche Form von alternativer natürlicher Energie in diesem Gebiet des Ligurischen Appennins darstellt. Die Energieproduktion eines echten Aerogenerators wurde über die Zeit integriert, um die Energieerzeugung für jede vom Flügel überstrichene Flächeneinheit für ein Jahr bzw. für einen Monat zu bestimmen. Unter der realistischen Annahme, daß die Leistung eineridealen Maschine 0.4 kWh/m2 beträgt, ergibt sich eine Jahresproduktion der Leistungsdichte von 645 kWh/m2 in 30 m Höhe über dem Boden. Es wurde berechnet, daß fünf durch Wind angetriebene mittelgroße Generatoren mit einem Flügel von 20 m Durchmesser etwa 1 GWh im Jahr erzeugen können.
    Notes: Summary A detailed analysis of wind energy availability at Mount Capellino (Genoa, Italy), based on wind data for a twenty year period, shows that wind energy is a promising renewable natural energy source in this part of the Ligurian Apennines. The instantaneous power output of a real aerogenerator has been integrated over the time to determine the energy output per unit area swept by the rotor over a year and a month respectively. Using a realistic capacity of 0.4 kW/m2 for theideal machine, the annual power density output is 645 kWh/m2 at 30 m above ground level. It is estimated that five medium size wind-powered generators of 20 m in rotor diameter can produce approximately 1 GWh per year.

    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.
