A new simple method of experimental determination of the instantaneous-velocity vector using a thermohydrometer is proposed. Constant monitoring of the measuring-apparatus parameters allows measurements to be made in a natural waterway flow.

The role of the subprocess $2\to 3$ $qg\to \bar{c}cq$, when there are quarks and gluons in the initial state, in reactions of the hadronic creation of charmed particles is considered.

The relation between the basic and meridional motion in a convective eddy is investigated. The velocity measurements are made by the method of laser anemometry. It is found that eddies of different kinds may be reduced to corresponding states.

By means of a method based on the use of the quasiclassical quantization condition, the asymptotic formulas, $(r \to \infty)$ for the correction $\Delta V(r)$ to the reference potential $V(r)$ of retaining type - $(\lim_{r\to \infty} V(r) = \infty)$ - are obtained in the case of change in the number of states and shift of the energy levels in the spectrum of the radial Schr$\stackrel{..}{o}$dinger equation. In the proposed method, the correction $\Delta V(r)$ as $(r \to \infty)$ is determined from an integral equation of Abelian type, which differs significantly from the standard methods of the inverse problem of quantum mechanics associated with solving the Gel'fand-Levitan equations.

On the basis of taking account of the asymptotic behavior of the free energy at small and large densities, phase transition in a system of solid spheres is described using series in terms of the density with improved convergence.

A preliminary analysis is made of the acoustical quantities of emission in critical conditions of the flow of an air current around the surface of a marine wave. It is shown that the displacement of the air-flow breakaway point over the surface of the marine wave in critical flow conditions may be a source of intrasound waves in the atmosphere above the oceans.

The magnetic states in the alloy $Fe_{34}Cr_{41}Co_{25}$ are investigated by the methods of M$\stackrel{..}{o}$ssbauer spectroscopy and thermomagnetic analysis. It is established that in the alloy, with various thermomagnetic treatments (at temperature of 610°C, H = 5000 Oe, and f = 70 Hz), stratification of the solid solution into antiferromagnetic, ferromagnetic and nonmagnetic phases occurs as a result of the separation of the intraphase segregations with the most probable configurations of the local atomic surroundings, the distribution of the relative proportions of which depends on the form of heat treatment.

The structure and some physical properties of a series of solid structures, eutectic compositions, and epitaxial layers are investigated. The study is performed on samples grown under conditions of microgravitation, in comparison with samples obtained under terrestrial conditions. Methods of optical and electron-raster spectroscopy, X-ray structural, and X-ray spectral analysis, photoluminescence, and cathode luminescence are used; quantum oscillational and optical effects are investigated. Certain peculiarities in the formation of the crystal and electronic structure of the material are observed.
