Estimation of the coefficient of turbulent diffusion for a solid impurity in a suspension flow
Yu.G. Pyrkin, I.B. Romanova, M.A. Silayev
An expression was derived for the coefficient of turbulent diffusion of solid particles (particulates) as a function of the parameters of a suspension flow. The variation of this coefficient with the flow depth was calculated on the basis of experimental data.

Internal gravitational and magnetic fields in the analysis of polar oscillations of the Earth's inner core
N.A. Chuikova, S.A. Kazaryan, S.L. Pasynok
The problem of polar oscillations of the Earth's inner core was solved according to the Slichter-Busse procedure with account taken of the forces induced by the attraction of the asymmetric cover of the Earth and by the presence of a magnetic moment in the inner core. The internal gravitational and magnetic potentials were simulated in the form of the potentials of a single layer located on the spherical surface of the outer core. Two models of the gravitational potential were considered. The first was constructed on the basis of the external gravitational field of the Earth and the second model was based on seismic data. It was found that the choice of the model has no appreciable effect on the frequency of possible oscillations of the inner core and strongly affects the displacement of the Earth's core.

Ionization of hydrogen in optically dense atmospheric layers of cool stars
E.A. Bruevich, N.A. Katysheva
The gas ionization parameter $(N_e) / (N_e+n_1)$ was calculated for various gas densities and temperatures by two probabilistic methods for solving steady-state equations. The results produced by these methods were compared with those obtained by other authors. It is shown that the ionization parameter of a gas depends rather strongly on its optical thickness, density and temperature.

Calculation of processes in inhomogeneous plates under local thermal actions
G.N. Medvedev and B.I. Morgunov
Thermal and mechanical processes arising under local thermal actions on plates made of a homogeneous or an inhomogeneous material are considered. If the material is inhomogeneous, its characteristics vary considerably with the coordinate corresponding to the thickness of the plate. External thermal perturbations are concentrated in a small region and have a significant value. Temperature and displacement vector are determined with the use of an asymptotic procedure.

The effect of topological self-action experienced by a stationary distribution of currents and charges on the space $M_2\times V_2$ ($М_2$ is the two-dimensional Minkowski space and $V_2$ is a two-dimensional Riemann surface) is examined. The case of a locally plane multiconic space is considered.

Higgs boson associative production by leptons in the field of an electromagnetic wave
K.V. Zhukovsky, P.A. Eminov
The probability of associative production of Higgs and Z-bosons by a charged lepton in the field of a plane electromagnetic wave of arbitrary intensity has been computed. It has been shown that in a particular case of a head-on collision of an electron with a low intensity wave when one photon is absorbed, the cross section of the process under investigation in the superhigh energy range increases according to a logarithmic law up to a value which is substantially greater than the cross section of the process $e^++e^-\to Z+H$ that takes place under similar conditions.

Detection of neutrons and $\gamma$-quanta under laboratory conditions and their separation by the scintillation pulse shape in CsI(Tl)
A.V. Bogomolov, I.N. Myagkova
Atmospheric neutrons and $\gamma$-quanta have been recorded separately under laboratory conditions with the aid of a CsI(Tl) scintillation crystal. The secondary charged products of interaction between neutrons and $\gamma$-quanta and the crystal material were identified by pulse shape in CsI(Tl). This technique allows one to detect a neutron flux (with energies $E_n>20$ MeV) of about $\sim 10^{-3} particles\cdot см^{-2}s^{-1}$ against a background of a $\gamma$-radiation flux which is an order of magnitude higher.
