The Stark broadening of the $H_\beta$ line of hydrogen was used to determine the concentration of electrons in a stimulated microwave discharge channel in nitrogen as a function of the gas pressure. At atmospheric pressure, the concentration of electrons in the nitrogen channel was found to be $(1\div 2) \cdot 10^{15}$ cm$^{-3}$.

M.Yu. Nikolaev, S.S. Semenov
The metallic model was used to carry out an exact evaluation of the off-diagonal components of the conductivity and polarizability tensors of the benzene molecule, which are essential for the determination of the Faraday effect.

Detection of temperature waves in thermally nonlinear media
L.P. Filippov, S.N. Kravchun, V.M. Abdulaeva
The harmonic of temperature oscillation due to the propagation of temperature waves in a liquid were observed in the region in which the thermophysical properties of the medium were highly temperature dependent (near the critical point).

S.A. Kirov, N.E. Syr'ev
An experimental study was carried out of absorption by a spherical sample of a nickel ferrite single crystal at frequencies in the range 3.4-?.8 GHz. Resonance oscillations due to the uniform electric field predicted by previous theoretical calculations were recorded for the first time.

V.A. Korotkii, Yu.N. Obukhov
A study is reported of spin dynamics for a Wayssenhoff liquid in a gravitational field. The following theorem is proved: the nontrivial spin of the Wayssenhoff liquid that satisfies the Frenkel condition is conserved if and only if the liquid moves without acceleration.

V.B. Gostev, A.R. Frenkin
It is shown that the level shift of the even states in the discrete spectrum, produced by the singular perturbation $\lambda |x|^{-\nu}$, can be described by the standard Rayleigh-Schroedinger formulas only for $0 < \nu < 3/2$.

Exact dynamic theories operating on a given background
A.N. Petrov, A.D. Popova
Exact dynamic theories induced by the subdivision of the variables in the original field theory into a background and a finite dynamic part are constructed. They exhibit a certain nonequivalence under different cases of the subidivied variables. Gauge invariance that follows from displacements in 4-space and dynamic theories in GTR are discussed.

Intermediate-energy behavior of the helicity of massive Dirac neutrinos when they are scattered by nucleons and its astrophysical aspects
B.K. Kerimov, A.M. Mourao, V.P. Tsvetkov
The differential and total cross sections for the elastic scattering of massive Dirac neutrinos by nucleons have been evaluated at intermediate energies ($E_{\nu}\ll M_N$), taking into account the neutrino helicity before and after scattering. The behavior of the neutrino helicity under the conditions prevailing in a neutron star has been investigated.
