The aim is to compare the mean values of the in vivo electrical characteristics of biological active points (BAPs) with those of the surrounding human skin. The impedance measurements at BAPs and on the surrounding skin are carried out in vivo on ten young, healthy people. The results of the measurements show that the BAP resistance RP is smaller, and the… (More)
Technical and economical aspects of application of solar electric systems in city transport are discussed, with the possible use of Sun tracking; the effect of the latter on the solar energy conversion efficiency is analyzed in application to stationary and moving platforms with photovoltaic solar panels. The option of using grid-connected solar panels is… (More)
The near integrability property is studied for a class of perturbed Hamiltonian systems with two degrees of freedom on a phase space whose symplectic form depends non-uniformly on a small parameter.
Cylindrical nanostructures, namely, nanowires and pores, with rectangular and circular cross section are examined using mirror boundary conditions to solve the Schrödinger equation, within the effective mass approximation. The boundary conditions are stated as magnitude equivalence of electron's Ψ function in an arbitrary point inside a three-dimensional… (More)
We report the results on infrared transmission measurements of non-doped and tellurium-doped crystals of zinc selenide grown from the melt. It was found that non-doped samples feature high transmission (50%-60%) for the wavelengths of 1-22 μm. The efficient scintillating crystals of ZnSe(Te) are almost opaque for λ>7 μm. Doping these samples with ytterbium… (More)
This paper is dedicated to study the thin polycrystalline films of semiconductor chalcogenide materials (CdS, CdSe, and PbS) obtained by ammonia-free chemical bath deposition. The obtained material is of polycrystalline nature with crystallite of a size that, from a general point of view, should not result in any noticeable quantum confinement.… (More)
