Global ecology prioritiesIl Nuovo Cimento C - Tập 15 - Trang 123-132 - 1992
K. Ya. Kondratyev
An attempt to substantiate priorities of global ecology has been undertaken with an emphasis on two principal aspects: 1) heat balance of the Earth and anthropogenically induced redistribution of its components; 2) closed nature of global biogeochemical cycles. It has been shown that the ecological faith of the Earth depends first of all on biosphere dynamics disturbed by man's impact. The Global ...... hiện toàn bộ
Integral imager: Prototype scientific performancesIl Nuovo Cimento C - Tập 16 - Trang 709-714 - 1993

The Imager proposed for the gamma-ray satellite project INTEGRAL is based on a multilayer two-dimensional array of CsI(TI) elements viewed by Si photodiodes. The total active area is ≈2500 cm2. The operative energy interval ranges from 0.05 to 10 MeV. A prototype version of this instrument, ready to be tested on a ballon-borne experiment, has been realized. In this article the expected performance...... hiện toàn bộ
Hadrons and other secondaries generated by cosmic-ray muons undergroundIl Nuovo Cimento C - Tập 18 - Trang 517-529 - 1995
F. F. Khalchukov, E. V. Korolkova, V. A. Kudryavtsev, A. S. Malguin, V. G. Ryasny, O. G. Ryazhskaya, G. T. Zatsepin, O. Saavedra
The production of nuclear-active and electromagnetic particles, as well as long-lived isotopes in nuclear and electromagnetic showers generated by cosmic-ray muons at different depths underground is discussed. Characteristics of the secondary components and their dependence on the depth and the muon energy, obtained in experiments and calculations, are presented.
Arguments in favour of a program of seismic detection of gravity wave burstsIl Nuovo Cimento C - Tập 13 - Trang 847-854 - 1990
A. V. Gusev, V. K. Kravchuk, V. N. Rudenko
The possibility is shown of selecting gravity wave perturbations in earth crust block in the seismic-noise background due to far local sources. It is shown that the utilization of different space-time «colourations» of gravity wave and noise perturbations makes it possible, in principle, to extract the signal in the background of noise of exceeding intensity.
The EAS-TOP calorimeterIl Nuovo Cimento C - - 1992

Galeotti, G. Mannocchi, C. Morello, G. Navarra, L. Riccati, O. Saavedra, G. C. Trinchero, P. Vallania, S. Vernetto
The muon-hadron detector of EAS-TOP is a 270 m2 calorimeter constructed inside the air shower array on the top of the underground Gran Sasso Laboratory (Italy). The general layout of the detector and the performances of the active part (streamer and proportional chambers) are presented.
The dependence of the cosmic-ray shower age on shower size for vertical sizes in the range 6·105Il Nuovo Cimento C - Tập 4 - Trang 668-672 - 1981
R. W. Clay, P. R. Gerhardy, D. F. Liebing, G. J. Thornton, J. R. Patterson
Measurements have been made of the electron lateral-distribution age parameter for cosmic-ray showers with sea-level sizes from ∼105 to 6·106 particles. It is found that, in the size range from ∼6·105 particles to ∼6·106 particles, the shower age decreases rapidly with size corresponding to a rapid change in the equivalent development depth with shower size. Measurements of the age distribution of...... hiện toàn bộ
The SO2 pollution in MadridIl Nuovo Cimento C - Tập 6 - Trang 605-617 - 1983
G. Finzi, R. García, E. Hernández
In this work, two different stochastic models will be considered, both oriented to the real-time forecast of daily SO2 pollution in Madrid. The first one is a «black-box» model, in which the input-output transfer function is identified by means of the methodology given by Box and Jenkins. The second one is a «grey-box» model with a simple reasonable structure in accordance with the physical laws o...... hiện toàn bộ
Some climatic studies on the regime of the river Mahanadi basinIl Nuovo Cimento C - Tập 2 - Trang 585-595 - 1979
A. A. L. N. Sarma, D. S. Rao
An attempt has been made in the present paper to study some of the climatic aspects of the moisture as well as thermal regimes of the river Mahanadi basin. This type of study finds its importance in finding out, not only the water potentialities of a river, but also the thermic conditions that favour the growth and development of vegetation at and around the basin. The basic elements required for ...... hiện toàn bộ
