genetic link between the excess and the primary cosmic rays. An estimate is made of the life of particles in an artificial belt with specular points at altitudes of 3OD-400 km. I. A. SAVENKO, N. F. F'ISARENKO,P. I. SHAVRINet al. : Measurement of the total radiation dose on “Vostok-S and “Vostok-6” (pp. 147-149) The results obtained from the data of the dosimeters on “Vostok-S and “Vostok-6” are described. The total doses of the pilots were: Vehicle “Vostok-5” “Vostok-6”
Flight time 119 hr 71 hr
Tissue dose, mrad 50 30
I. A. SAVENKO, P. I. SHAVIUN,N. F. PLYARENKO et al.: Measurement of the soft radiation in equatorial latitudes on “Cosmos-4” (pp. 150-153) The soft corpuscular radiation was measured by a scintillation counter. Analysis of the data indicates that “equatorial” radiation consists of electrons with energy greater than 3 . 104 eV. The intensity of the recorded streams varies in the range lop-lo6 particles/cma/sec. V. I. MYA~NIKOV: Changes in the electroenceuhalogram of a man during prolonged isolation (pp. 154-161) This paper gives the dynamics of the main-indices of electroencephalograms (frequency, alpha-rhythm amplitude) and the response to switching off a light stimulant in prolonged isolation with different modes of dailv activitv. In exueriments with the usual conditions the amplitude of the alpha-rhvthm of the initial cize f&electroencephalogram decreased with no change in >requency, whilsi in exberiments with the shifted routine the decrease in amplitude of the alpha-rhythm was accompanied by the appearance of diffuse slow waves and exhaltation of the alpha-rhythm after the stimulant. The changes in bio-electric activity give grounds to suppose that inhibition develops in processes of the central nervous system under investigation.

G. V. SAMOILOVICH:Evolution of the orbit of a circular Earth-spheroid satellite (pp. 179-197) Using the small-parameter method, analytical relationships are found describing the perturbed motion of an artificial Earth satellite under the influence of the second zonal spherical harmonic of the Earth’s gravitational potential. The resulting equations are used for a qualitative investigation of the shape and position of osculating orbits of circular and almost-circular satellites. P. YE. EL’YASBERG:Approximate formulae for determining the life of artificial Earth satellites (pp. 198-218) Approximate formulae are deduced for determining the life of low-altitude satellites for which the disturbing influence of the Sun and Moon can be ignored. They cover the total possible range of variation of eccentricity 0 < e < 1. The errors are estimated. V. I. KRASSOVSKII:Polar aurora and night sky emission (pp. 219-231) The latest data are presented concerning polar aurora and the related night sky emissions. observations are made and directions of necessary research are indicated.

A. V. GUREVICH: Electric-field intensity on the surface of a body in plasma (pp. 232-245) The structure of the charged layer on the surface of a body in a plasma is investigated. The intensity of the electric field on the body’s surface is determined. It is shown that such measurements can be used for determining the directional velocity of ions in the ionosphere. M. S. MALKEVICH: Some problems io interpreting radiation measurements from satellites (pp. 246-256) Methods of determining some physical parameters of the atmosphere and basement surface from radiation measurements in different spectral regions on artificial Earth satellites are considered. Appropriate methods of solving the reverse problems are illustrated by examples (determination of the temperature of the atmosphere and basement surface, the mass of matter absorbing radiation and the altitude of the upper boundary of cloud). Consideration is paid to atmospheric “noise” in determining the spatial structure of the basement surface. 5
