“…The amplitude dependence of the potential difference is nearly linear for small amplitudes, the linearity remaining within a certain amplitude range where internal friction becomes already amplitude-dependent. (The above mentioned regularities 1 and 2 were observed by the authors earlier on Lip crystals [3]. )…”

Dislocation internal friction and electric polarization effect, which results from charged edge dislocation displacement (Stepanov's effect) have been investigated in NaF crystals by means of composite oscillator technique. Some parameters of thermally aided edge dislocation depinning are calculated on the basis of experimental data combined with the results of the theoretical work by Indenbom and Chernov. The parameters are shown to be almost the same for both edge and screw dislocations.

The Russian Academy of Sciences and Federal Space Agency, together with the participation of many international organizations, worked toward the launch of the RadioAstron orbiting space observatory with its onboard 10-m reflector radio telescope from the Baikonur cosmodrome on July 18, 2011. Together with some of the largest ground-based radio telescopes and a set of stations for tracking, collecting, and reducing the data obtained, this space radio telescope forms a multi-antenna groundspace radio interferometer with extremely long baselines, making it possible for the first time to study various objects in the Universe with angular resolutions a million times better than is possible with the human eye. The project is targeted at systematic studies of compact radio-emitting sources and their dynamics. Objects to be studied include supermassive black holes, accretion disks, and relativistic jets in active galactic nuclei, stellar-mass black holes, neutron stars and hypothetical quark stars, regions of formation of stars and planetary systems in our and other galaxies, interplanetary and interstellar plasma, and the gravitational field of the Earth. The results of ground-based and inflight tests of the space radio telescope carried out in both autonomous and ground-space interferometric regimes are reported. The derived characteristics are in agreement with the main requirements of the project. The astrophysical science program has begun.
