Evidence of internal gravity waves in the lower thermosphere at midlatitudesIl Nuovo Cimento C - Tập 4 Số 1 - Trang 1-25 - 1981
Cevolani, G., Formiggini, C.
Wind measurements were made by the CNR Meteor Radar Station at Budrio (45°N,
12°E) in the April–September 1978 period in order to emphasize the role of
internal gravity (IG) waves in the lower thermosphere ((80÷110) km). After
briefly describing the basic properties of these waves, we determine some of
their characteristics using both the conventional spectral-analysis methods and
alternatively, f... hiện toàn bộ
Diffuse galactic and extragalactic radiation in the far infra-redIl Nuovo Cimento C - Tập 8 Số 4 - Trang 353-367 - 1985
Ceccarelli, C., Dall'Oglio, G., De Bernardis, P., Masi, D., Melchiorri, B., Melchiorri, F., Moreno, G., Pietranera, L.
We present the results of a balloon flight devoted to the observation of the
diffuse sky radiation in the wave-length region (150÷400) and (350÷3000) μm, at
angular scales larger than six degrees. Observations of dust emission and
distribution are discussed.
Solitary waves in the gulf of quarnaro revealed by LANDSAT thematic mapperIl Nuovo Cimento C - Tập 17 Số 2 - Trang 143-152 - 1994
Borzelli, G., Marullo, S., Ligi, R., Cannizzaro, G.
The propagation of solitary wave trains in the Adriatic Sea is studied by means
of LANDSAT Thematic-Mapper images. The baroclinic Rossby radius of deformation
has been estimated from the width of a baroclinic current observed along the
coast of Croatia using AVHRR data. The phase speed of the linear internal waves
has been consequently estimated and the compatibility of the Kortweg-de Vries
equati... hiện toàn bộ
A propos des formules de SuttonIl Nuovo Cimento C - Tập 1 Số 5 - Trang 389-394 - 1978
Lacaze, J.
The establishment of the fundamental Sutton's formula is criticized; this
formula is recovered by a more correct mathematical reasoning, and generalized.
Applications are only evoked. Si critica l'impostazione della formula
fondamentale di Sutton; si ricupera questa formula con un ragionamento
matematico più corretto e la si generalizza. Alle applicazioni si accenna solo.

Solar neutrinos, the presolar abundance of helium and the solar metallicityIl Nuovo Cimento C - Tập 9 Số 3 - Trang 714-724 - 1986
Rana, N. C., Wilkinson, D. A.
The observational estimates of the presolar abundance of helium (Y s) are
reviewed and a lower value ofY s ({-0.19 by mass fraction) is suggested to solve
the solar-neutrino problem. With this reduced value ofY s it is argued from the
point of view of maintaining the luminosity of the Sun at its observed level
that the metallicity requirement isZ s{-0.013. Previous workers, while
considering lower... hiện toàn bộ
Measurement of cosmogenic radionuclides in meteorites with a sensitive gamma-ray spectrometerIl Nuovo Cimento C - Tập 15 Số 1 - Trang 99-104 - 1992
Bonino, G., Castagnoli, G. Cini, Bhandari, N.
A large-volume HPGe gamma-ray spectrometer in a NaI(Tl) well has been set up
underground at 70 m.w.e. depth for whole body counting of cosmogenic
radionuclides in meteorites. The detectors are housed in a 20 cm thick lead
shield with a lining of cadmium and OFHC copper. The scintillator is
simultaneously operated in anticoincidence as well as in coincidence in selected
energy channels to achieve l... hiện toàn bộ
The «lugo» fireball of January 19, 1993Il Nuovo Cimento C - Tập 16 Số 4 - Trang 463-471 - 1993
Cevolani, G., Foschini, L., Trivellone, G.
Observational data and the theory of the interaction of meteoroids with the
Earth’s atmosphere enable us to characterize the spectacular fireball which was
observed to cross Northern Italy from SE to NW on January 19, 1993, ending at
about 00∶33 h UT with an explosion approximately over the town of Lugo di
Romagna. For estimated visual magnitudesM v=−22⋎−25 at the peak of the light

Theoretical and experimental power spectra of neutron monitor time series in 1978Il Nuovo Cimento C - Tập 3 Số 3 - Trang 267-272 - 1980
Bergamasco, L., Alessio, S.
A comprehensive model for the spectral analysis of neutron monitor data is
presented. The contributions to the power spectrum include scintillations in the
interplanetary magnetic field caused by cosmic-ray diffusion along and
perpendicularly to the field and Forbush-decrease effects. The effects of the
Earth's rotation and of nonlinear interactions between particles and fields are
taken into acco... hiện toàn bộ
The experiment OPERA for the mission InterballIl Nuovo Cimento C - Tập 13 Số 1 - Trang 155-161 - 1990
Amata, E., Baldetti, P., Bellucci, G., Formisano, V., Morbidini, A., Orsini, S., Pavoni, A., Terenzi, R., Viterbini, M.
An experiment for measuring the electric field along 2 axes from quasi-static DC
to kHz called OPERA is being produced at IFSI for the USSR mission Interball. An
experiment description is given here. The experiment is in collaboration with
ESTEC (ESA) and LPCE (Orléans, France).
Reversible electron heatingvs. Wave-particle interactions in quasi-perpendicular shocksIl Nuovo Cimento C - Tập 15 Số 5 - Trang 607-619 - 1992
Veltri, P., Mangeney, A., Scudder, J. D.
The energy necessary to explain the electron heating in quasiperpendicular
collisionless shocks can be derived either from the electron acceleration in the
d.c. cross shock electric potential, or by the interactions between the
electrons and the waves existing in the shock. A Monte Carlo simulation has been
performed to study the electron distribution function evolution through the
shock structure... hiện toàn bộ
