Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

... Journal: 1973, Astron Zh., ... The isotopic shifts of helium spectral lines have been measured for four high velocity OB-stars and one standard star. The spectrograms were secured at 2.6 m reflector of the Grimean observatory, dispersion beging 8 / mm . All five stars did not show the systematic isotopic shifts. But three lines of 53 Ari have shown shifts which are in agreement with theoretical ones, but other helium lines did not show such shifts. ...

... Maxim was one of the leading analysts of Russia space activities, those who set the basis for the open independent analysis of then-Soviet space program. q In the early 1990s the small blue paperback book became a real breakthrough. In the time being, almost everything is allowed; in that time, even the title of the book - The Military . ... I believe that to open Maxim's files and archives for the experts and Russian space program enthusiasts would be a best thing we can do in memoriam. ...

The main task of the multimedia lectures "Life of the Earth in the Solar Atmosphere" is to introduce wide range of users to the basic physical characteristics of the Earth, the near-Earth space and the Sun, which mainly forms the properties of the mentioned objects and is responsible for their variations (so-called "space weather"). ...

Fibre composite materials were quite well researched in WW 2 and after but failed to make great impact because a stiff and unavailable fibre was lacking. ... The requisite stiffness of composites is known and it is understood how to use it in engineering situations. The problem of toughness of fibre composites is less well understood. Some of the impressive artefacts made from fibre composites are described and their use in the Airbus A380 and Boeing 787 described in a little detail. ...
