Dimer percolation and jamming on simple cubic lattice
Yu. Yu. Tarasevich,V. A. Cherkasova
Physics , 2007, DOI: 10.1140/epjb/e2007-00321-2
Abstract: We consider site percolation of dimers (``neadles'') on simple cubic lattice. The percolation threshold is estimated as $p_c^\text{perc} \approx 0.2555 \pm 0.0001$. The jamming threshold is estimated as $p_c^\text{jamm} = 0.799 \pm 0.002$.

Cardiac biopotentials influence on central nervous system functioning: first steps in hypothesis verification
Shvarts Yu.G.,Cherkasova S.A.,Kondal'skaya Yu.O.
Saratov Journal of Medical Scientific Research , 2012,
Abstract: The research goal is to verify the hypothesis on influence of cardiac biopotentials on central nervous system. Materials: 20 healthy individuals aged 18-26 years old have been participated in the investigations. Two groups composed of 10 patients each have been formed. Double increase in heart biopotentials by means of artificial impulse insertion between natural cardiac contractions has been modeled. Artificial impulses have been similar to unaffected ones, produced in a normal heart work. Additional impulses have been generated using external pacemaker and have been linked up with electrodes on the chest. They have been synchronized with the heart rhythm and located in-between R waves. The duration of those impulses has been fully matched to ventricular complex. Their amplitude has been adjusted individually depending on the height of R wave. Nervous system mobility has been used as the indicator reflecting the central nervous system functioning. Degree of mobility has been defined on the basis of tapping test results. The test has been repeated at specific intervals. Groups have been exposed to two adverse testing modes. Additional impulses have been conducted to the patients of group I within an hour over a period of the first and the third 15-minute intervals and to the patients of group II over a period of the second and the fourth 15-minute intervals. In the middle and in the end of each time interval tapping test has been carried out. After preliminary analysis two other modes of stimulation have been tested. The stimulation has been performed within the 40-minute course: over a period of the first 20-minute interval and vice versa. Results: Detailed evaluation has revealed that short-time increase of nervous processes has been checked in combination with decrease in their stability. Conclusion: The data obtained have shown that there is possible influence on central nervous system functioning. The article ends with prospects of further investigation.
Percolation of the aligned dimers on a square lattice
V. A. Cherkasova,Yu. Yu. Tarasevich,N. I. Lebovka,N. V. Vygornitskii
Physics , 2009, DOI: 10.1140/epjb/e2010-00089-2
Abstract: Percolation and jamming phenomena are investigated for anisotropic sequential deposition of dimers (particles occupying two adjacent adsorption sites) on a square lattice. The influence of dimer alignment on the electrical conductivity was examined. The percolation threshold for deposition of dimers was lower than for deposition of monomers. Nevertheless, the problem belongs to the universality class of random percolation. The lowest percolation threshold (pc = 0.562) was observed for isotropic orientation of dimers. It was higher (pc = 0.586) in the case of dimers aligned strictly along one direction. The state of dimer orientation influenced the concentration dependence of electrical conductivity. The proposed model seems to be useful for description of the percolating properties of anisotropic conductors.
The Use of Highly Dispersed Iron-bearing Composites in Treatment and Diagnosis: Advances and Problems
O.G. Cherkasova,E.Y. Shabalkina,Yu.Ya. Kharitonov,S.N. Tsybusov
Sovremennye Tehnologii v Medicine , 2012,
Abstract: There have been considered new effective medical technologies using highly dispersed iron-bearing magnetic particles. A considerable number of versatile options of obtaining such particles ahs been shown. Regardless the methods for their production, highly dispersed iron-bearing magnetic particles are composites consisting of metal nucleus and surrounding protective capsule of complex mixture. Their critical characteristic is the imaging possibility using magnetic resonance tomography, local heating by high-frequency magnetic field to initiate the mechanism of drug releasing. There have been given the methods of having an impact on the obtained highly dispersed iron-bearing particles by changing their morphology: sizes, shorms, compositions, qualitative and quantitative ration “nucleus–membrane”. There have been specified yet unsolved problems: adequate estimation of such particles, the development of industrial regulations to obtain highly dispersed magnetic iron-bearing composites with tailor-made properties.

Decay of cosmological constant as Bose condensate evaporation
Irina Dymnikova,Maxim Yu. Khlopov
Physics , 2001, DOI: 10.1142/S0217732300002966
Abstract: We consider the process of decay of symmetric vacuum state as evaporation of a Bose condensate of physical Higgs particles, defined over asymmetric vacuum state. Energy density of their selfinteraction is identified with cosmological constant $\Lambda$ in the Einstein equation. $\Lambda$ decay then provides dynamical realization of spontaneous symmetry breaking. The effective mechanism is found for damping of coherent oscillations of a scalar field, leading to slow evaporation regime as the effective mechanism for $\Lambda$ decay responsible for inflation without special fine-tuning of the microphysical parameters. This mechanism is able to incorporate reheating, generation of proper primordial fluctuations, and nonzero cosmological constant today.
Application of prodigiosin as a colorant for polyolefines  [PDF]
Irina Ryazantseva, Irina Andreyeva
Advances in Biological Chemistry (ABC) , 2014, DOI: 10.4236/abc.2014.41004
Abstract: Serratia marcescens strain 9986 is a producer of prodigiosin used as a dye of polyolefines (polyethylene, ultratene). The biosynthesis of pigment was closely connected with controlled growth parameters. A prodigiosin yield 0.2 - 0.4 mg per l of culture medium in the batch culture under aerobic conditions was obtained. Prodigiosin was extracted from crude biomass treated by 0.1% of sodium dodecyl sulfate (SDS). This novel elaborated stage is necessary for thermostability a dye in polymer. The consumption of prodigiosin preparation is more economical in the technology of the coloration of polyolefines. The elaborated method has been manufactured for dyeing polyethylene by biological pigment-articles of the common use corresponding to the technological standard.
