    Notes: We studied current and electric field transients in high resistivity CdTe:In crystals by means of nanosecond time-resolved photocurrent and electro-optic sampling measurements. Electron and hole dynamics have been investigated for different excitation regimes (incident photon fluence and wavelength). A numerical solution for a drift-diffusion model in presence of several defect centers is given which allows to interpret experimental results. Current decay can be described by two time constants of about 10 and 100 ns, the first one being predominant for low incident photon energy (〈1 eV). By comparison with the numerical model, the fast and slow time constants are related to hole and electron trapping, respectively. Electric field decays in a millisecond time scale. This is related to charge trapped in a deep recombination center located at 0.75 eV from the conduction band. © 2000 American Institute of Physics.

    Notes: Summary The paper describes some characteristics of the precipitation patterns in the plain of Friuli-Venezia Giulia. Even if small, this Region shows a complex rainfall pattern so that, by previous studies, it was divided into four distinct areas with peculiar pluviometric regimes, namely the Coastal Area, the Plain and Hills Area, the Prealpine Area and the Inner Alpine Area. Nowadays a new data set, collected by the ERSA/CSA automatic stations, allows to propose a new sub-classification of the Coastal Area and Plain and Hills Area, under the point of view of the hourly rate of precipitation. This new sub-classification is composed by five zones: the Coast, the Carso, the Low Plain, the Middle Plain and the Piedmont. Each one of these zones presents a peculiar seasonal behaviour of the hourly rain-rate.
