The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ... There are many methods to solve the light-scattering problem for a homogeneous spheroid (our survey of the light-scattering methods see here ). ...

... Technique of supervision of solar atmosphere active formations with the Multichannel Flare Spectrograph. Consider in details now a method of observations of fast processes in solar chromosphere with Multichannel Flare Spectrograph (MFS) installed in Ondrejov Observatory (Czech Republic). ... The working spectral range lies between IR CaII 8542 A and K CaII 3870 A. To observe solar image on the spectrograph's slit a lens, narrow-band H-alpha filter (4) ("Daystar") and CCD-chamber are used. ...

Super Rocket Targets . NPO MOLNIYA has been designing rockets-targets for over 30 years using the great experience in crea-ting anti-aircraft guided rockets (AGR) for C-25M. On the basis of B-300 anti-aircraft rockets which expired their service life, there were designed, tested and put into the serial production the following types of the rocket - ... The analogue of this system successfully passed the state tests with the ZVEZDA-4 rocket-target. ...
