COMPENSATING ROLE OF SELF-EQUILIBRATED STRESS FIELDS IN CONSTRUCTING NON-SINGULAR SOLUTIONS USING A NON-EUCLIDEAN CONTINUUM MODEL FOR AN INCOMPRESSIBLE SPHERE

Journal of Applied Mechanics and Technical Physics - A self-equilibrated stress field for an incompressible sphere is constructed based on a non-Euclidean continuum model. The...     

Influence of boundary conditions on statistical characteristics of the wavefield in a layered randomly inhomogeneous medium

We consider the problem of the oblique incidence of a wave on the half-space of a layered randomly inhomogeneous medium without absorption and analyse the influence of boundary conditions on the probability distribution of the reflection coefficient phase, and the statistical behaviour of the wavefield intensity moments inside the medium.

Phase fluctuations and localization length in layered randomly inhomogeneous media

We consider the problem of the inclined incidence of a plane wave on the halfspace of a randomly inhomogeneous layered medium without absorption. The probability distribution of the reflection coefficient phase with respect to the incidence angle is calculated. With the help of this distribution we analyse the quantities connected with localisation effects—the length localization and moments of the intensity inside the medium.     

X-ray spectral study of a material containing BN nanostructures

The multicomponent substance obtained by laser evaporation of the BN target under nitrogen was studied by X-ray fluorescence and X-ray absorption spectroscopy. The BK _α spectra of the substance and boroncontaining compounds rh-BN, B₂O₃, and α-B were measured on a laboratory instrument using an ethyleneglycol distearate crystal as an analytical element; X-ray absorption spectra near the boron and nitrogen K edge were recorded on a BESSY synchrotron radiation station. The contents of the components in the synthesized substance were evaluated by decomposing the BK _α spectrum into the spectra of the test boron-containing compounds. A comparison of the X-ray absorption spectra near the NK edge of the substance and rh-BN revealed that BN nanostructures obtained by laser evaporation were defective.
