It is shown that in this very general framework the well established anti-correlation between variability amplitude and wavelength can only be understood as an effect of an underlying spectral component which remains stable on long time-scales, and is redder than the variable component. ...

... This method is based on putting space modules, vehicles and EVA-suit donned cosmonauts in the swimming pool under conditions of neutral buoyancy, indifferent equilibrium and unsupported state. ... You can also dive into the swimming pool with the SCUBA equipment in order to examine the mock-ups of space stations and vehicles and pass a course of rehabilitation in a hyperbaric oxygenation complex. ...

Text of report The subject if our report is the influence of the structure and physics of the uppermost superadaibatic layers on the oscillational spectrum of p-modes. ... In our report we will try to use a most simple representation of the spectrum, plotting the differences between theoretical (that is models') and observational frequencies against a frequency. ... It allow us to focused on the effects of the uppermost layers and ignore possible sophistications from effect of more deeper layers. ...

Irregular phenomena in the Earth Pole oscillation process and temporal variations of geopotential Valery Bondarenko, Vadim Perepelkin s The observed irregular phenomena in the Earth Pole oscillation process are very variety. ... These phenomena indicated in the IERS data are the "abnormal" fluctuation of the Earth Pole coordinates which owing to changing of the geodynamical parameters gives negative result in interpolation and forecast of the first approximation mathematical model. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...

ASTEROIDAL DAMAGE TO THE EARTH: IMPLICATIONS BY ASTEROIDS ­ RUBBLE PILES. ... 13, Moscow 119892, Russia, E-mail:san@sai.msu.ru In the cause of asteroids ­ rubble piles its effective cross-section of collision to the Earth is determined not by consolidated body, but by cluster of its fragments. Since the stage of rubble ­ piles may be ~108 years (see our communication at previous symposium), it may be significant for estimation the asteroidal damage to the Earth. ...

... OF MIR ORBITAL COMPLEX HARDWARE . ... Insufficient funds were compensated for by RSC Energia through of Contract activities. More than 60% of the entire scope of research both under the Russian, and International programs were performed on the MIR Station from 1995 through 2000. Within the final period (1997 - 2000) after the MIR final configuration as a research laboratory was completed, 138 space experiments were implemented under the science and application research program. ...
