Influence of external tidal and meteorological forces on the bradyseismic phenomenon in the Phlegraean Fields

Peculiar lunar echoes at 13.866 MHz
Il Nuovo Cimento C - Tập 1 - Trang 248-258 - 1978
Peculiar lunar echoes obtained with a radar operating at 13.866 MHz are presented and discussed. Some of their features are reconduced to a total or to a partial guidance by ionospheric and magnetospheric irregularities aligned with the geomagnetic lines of force. Precisely, such irregularities are intervening as natural wave guides or as leaky-wave antennas. In the latter case they are characteri...... hiện toàn bộ
Annual soil temperature evolution
Il Nuovo Cimento C - Tập 14 - Trang 251-261 - 1991
A model to study the annual behaviour of the temperature of a homogeneous solid (considered like a semispace) will be presented in this paper. The model gives the temperature of the solid at any time and at any depth. It assumes the solar flux as the incoming flux, constant atmospheric effects and a simple expression for the outgoing flux. Finally solutions of the soil temperature, when a meteorol...... hiện toàn bộ
The EXOSAT and Einstein observations of 1E0630+178 («Geminga») as complementary data sets
Il Nuovo Cimento C - Tập 7 - Trang 741-747 - 1984
Data for the soft X-ray source 1E0630+178 are now available from four independent measurements of the Einstein and EXOSAT missions. These are presented and compared in the light of the different characteristics and energy response of the different X-ray imaging detectors used (IPC, LE 1, LE 2). The time variability on medium (∼ hours) time scale is also investigated.
Variability of the terrestrial window and its physical implications
Il Nuovo Cimento C - Tập 12 - Trang 487-494 - 1989
We show that the frequencies of atmospheric molecular thermal vibrations significantly influence the spectral positioning of the terrestrial window. The bandpass filtering process of this window is confined to the region starting from theE-region and extending to an altitude not exceeding about 600 km. This indicates that a significant part of the infrared radiation emanating from lower altitudes ...... hiện toàn bộ
Ĉerenkov radiation in large cosmic-ray air showers
Il Nuovo Cimento C - Tập 1 - Trang 315-334 - 1978
A synchronized array of fast photomultipliers has been used to reconstruct the image in Ĉerenkov light of individual large cosmicray showers high in the atmosphere. The details of the images are in agreement with simulations based upon conservative models for cascade development. Observation of the fluctuations of the image between showers may enable the mass of the energetic cosmic rays to be det...... hiện toàn bộ
Detection of coherent elastic neutrino scattering on nuclei, a status report for a detector development based on metastable superconductors
Il Nuovo Cimento C - Tập 9 - Trang 598-604 - 1986
Coherent elastic neutrino scattering on nuclei can only be detected via the recoil energy of the nucleus. We try to develop a detector based on metastable superconducting grains to detect these small recoil energies. Experiments testing some fundamental properties of a detector using metastable Sn and Cd grains are presented. In the case of Cd a sensitivity of at least 24 eV/μm3 (normalized to the...... hiện toàn bộ
