          <abstract lang="ENG">Theoretical approaches which allow to calculate spectral dependences of external quantum yield of multijunction tandem solar cells have been considered; spectral characteristics of single-junction Ge, double-junction GalnP/GaAs and triple-junction GalnP/GaAs/Ge solar cells were calculated. The possibility of application of these approaches to investigation of minority carrier diffusion lengths in active regions of the solar cells through the comparison of experimental and calculated spectral characteristics was shown. Found out the values of minority carrier diffusion lengths for the layers of GalnP/GaAs/Ge solar cells, which provide almost full collection.</abstract>

          <abstract lang="ENG">The authors assume that cells adsorbed on drops can experience an excessive metabolism of a hydrophobic substratum and the process emits intermediate products of oxidation to increase mitochondrial and cytoplasmic membranes permeability, separate oxidizing phosphorylation process, raise consumption for maintenance of vital functions and increase energy dissipation. This mechanism is similar to maintenance of temperature in cells of warm-blooded animals brown fat running into hibernation.</abstract>

          <abstract lang="ENG">The turn of a polarization plane of the light disseminated at app. 180° by the erythrocytes suspension in physiological solution, diluted with a buffer solution is found in external magnetic field. Verde constant and coercive force are defined. Results are interpreted on the basis of a model according to which magnetic properties of blood are caused by the magnetic moment of the heme, being a part of a myoglobine molecule and containing a bivalent iron ion in the porphyrine ring.</abstract>

          <abstract lang="ENG">The paper is devoted to the theoretical investigation of weak resonance structure associated with 45 -» np transitions in atomic Kr and its isoelectronic ions Rb+, Sr2*, Y3+. The calculating method, which combines inter-channel interaction, dynamic polarization and screening effects to get the resonance parameters with many-electron correlations taken into account, is developed. Cross section curves and Fano's parameters for transitions to the low lying excited states are obtained within the frame of this method. The resonance profile changes from "window"-type structure to Lorentz-like peaks along Kr isoelectronic series.</abstract>

        <abstracts>
          <abstract lang="ENG">In this contribution we have briefly analyzed the approach on the basis of semi-empirical calculation of the potential barrier for molecule internal rotations. In opposite to it, we have suggested the another way how to find this barrier on purely theoretical grounds. For this purpose, we have used the bond-charge model with clamped charges, and in this contribution restricted ourselves by the simplest case of such molecules as ethane. It was found that this approach leads to theoretical results which are in a good agreement with experimental data. It means that the electronic theory of molecule vibrations developed earlier has a large degree of generality and can be used to study not only vibrations but also rotations of molecules and macromolecules on the basis of one and the same approach, excluding a lot of empirical parameters.</abstract>

          <abstract lang="ENG">The lidar equation for the Raman back scattering by benzene and toluene molecules computer simulation in the ranging distance from 0.1 up to 5 km at the YAG-Nd laser radiation wavelengths of 532, 355 and 266 nm has been fulfilled. It has been established that the optimal for the signal to noise ratio criteria and Raman power maximal value recording in such a lidar system is the laser radiation wavelength of 266 nm at the distance up to 1.7 km.</abstract>
