Authors: Navolokin N. A., Matveeva O. V., Maslyakova G. N., Bucharskaya A. B., Suleymanova L. V., Kun S. M., Medvedev B. A., Ignatiev A. A., Bochkaryeva T. V.

The cytotoxic effect of iron nanoparticles of size of 70 nm was studied in an experiment with single intramuscular and oral administration in albino mice and rats. Morphological changes were assessed in the internal organs, brain and the injection site. Studies had shown that intramuscular changes are more pronounced than when nanoparticles were administered orally and were shown in signs of cell damage while after the oral administration the blood flow changes in vessels were noted.

Authors: Postnov D. D., Sosnovtseva O. V., Postnov D. E.

By means of numerical experiment, we studied the oscillating patterns, generated by the interaction of nephrons in the vascular tree and compared them with experimental data. Based on these results we calculated the blood flow in all branches, as well as its Fourier power spectra, to characterize its spectral composition. We reveal the mechanism responsible for the effective localization of hemodynamic interaction based on elimination of modulation rhythms of blood flow at each branching level.

Authors: Ponomarenko V. I., Prohorov M. D., Sidak E. V.

We propose the method for the reconstruction of firstorder timedelay systems from their time series. The method is based on taking into account the type of the system equation at the regression model construction. The method allows one to recover the delay time, the parameter characterizing the inertial properties of the system and the nonlinear function. It can be applied to the recovery of timedelay systems performing chaotic and periodic oscillations.

Authors: Levtchenko B. B.

In the framework of the Dirac model of vacuum the creation of е+е− pairs in a constant and uniform electric field with allowance Coulomb interaction between е+ and е− is considered. The transmission coefficient via the energy gap deformed by external field and the electric fields of particles is calculated in the semiclassical approximation. The Sauter exponential factor is modified by the exactly calculated function G(y) accounting Coulomb interaction of particles and changes in the shape of the potential barrier.

Asymptotic Freedom into the Mechanics of Composite Particle Inelastic Collisions at High Energies

Authors: Fadeev N. G.

The application of the asymptotic freedom hypothesis to consider the mechanics of deep inelastic scattering processes (DIS), allows one to reveal the elastic form of the parton (xama and xbmb) scattering also for hadron-hadron interactions of particles a and b having masses ma and mb with subsequent hadronization of them into the hadron showers. The elastic character of the parton scattering, in its turn, helps to define invariant variables analogoues to DIS (Bjorken xa, xb and square four-momentum transfer Q2) through the two-hadron showers in the c.m.s. of a and b particles.

Modulating Effect of High-Frequency Electromagnetic Radiation on Hydrogen Sulfide Toxicity

Authors: Baulin S. I., Kartsev V. N., Shantrokha A. V.

On the basis of experimental investigation it is determined that highfrequency electromagnetic radiation of low intensity has a significant effect on the development of hydrogen sulfide toxicity during the inhalation process. Toxicity parameters reduce by 5–6 times if hydrogen sulfide is exposed to rays. The reduction of gas toxicity is obviously connected with appearance of quasi-stable intermolecular bonds that is the reason of dimer formations.
