New data on the basement of Franz Josef Land, Arctic region
We have studied pebbles of igneous rocks from the Lower Jurassic sedimentary succession of Hall Island, Franz Josef Land. Pebbles are represented by felsic intrusive and extrusive rocks, often cataclased and g...

The Influence of the Finite Size of the Light Spot on the Laser Induced Reorientation of Liquid Crystals
The threshold intensity for the laser induced deformation of nematic liquid crystals is calculated as a function of the spot size of the illuminating beam. It is shown, that due to the small size of the light ...

Reorientation of Liquid Crystals by Superposed Optical and Quasistatic Electric Fields
The electric field of a CW laser beam can reorient a nematic liquid crystal. Experiments on the influence of a superposed quasistatic electric field are reported showing that this can reinforce or weaken the l...

The effect of an optical field on the nematic phase of the liquid crystal OCBP
We have observed a complex structure and an extraordinarily large divergence (30–40°) of an argon-laser beam emerging from an OCBP crystal placed at a focal constriction. The experimental results can be explai...

Analysis of data on the vibrational-relaxation constants in CO2−N2−H2O mixtures, and optimization of a gasdynamic CO2 laser
The optimum stagnation parameters and compositions of the C02-N2-H20 mixture are optimized on the basis of data on the vibrational-relaxation constants. The influence of the uncertainty in the relaxation constant...
