EDUCATIONAL AND PRODUCTION PRACTICIANS AS MEANS OF FORMATION OF COMPETITIVENESS OF FUTURE SECRETARY-REVIEWERS [№ 8 ' 2016]
The article considers opportunities of educational and industrial practice in forming competitiveness of a future specialist using the example of a secretary-reviewer. The authors base their work on the studies of individual competitiveness researchers (N.G.Ageeva, V.Adolf, V.I.Andreev, Y.V.Andreeva, R.Y.Ahmetshin, L.A.Bodian, M.G.Vetrova, N.A.Zhuranova and others). The authors mentioned believe, that at the heart of competitiveness there is risk-taking, self-confidence, hard work, resistance to stress, clear goals and value orientations etc. The authors elicit professionally important personal features of a secretary-reviewer, basing on her professiogram developed by E.S.Romanova. The professiogram elicits such professionally important personal features as high sustainability to disturbances, good motor skills, well-developed auditory and visual memory, being able to sort out handwriting, emotional resistance, punctuality, carefulness, orderliness, reliability, tactfulness, communicability etc. In the article the authors describes experimental work, carried out in Orenburg Humanitarian and Technical college. The conclusion is made that competitiveness of future secretary-reviewers can be risen considerably during educational and industrial practice.

MOLECULAR DYNAMICS OF ADSORPTION HOMOGENEOUS POLYPEPTIDES ON THE SURFACE OF GOLD NANOPARTICLE [№ 13 ' 2015]
Conjugates of gold nanoparticles with macromolecules and molecules-marks are used to create biosensors and functional nanosystems in nanoelectronics. Conformational dynamics and the nature of the location of the macromolecules on the surface of the gold nanoparticles affects the kinetics of energy transfer between molecules-marks, the kinetics of two-stage photoreactions involving electronically excited molecules and oxygen molecules. In such a system of cluster type is formed by complex kinetic mode of energy transfer as a result of local plasmon-initiated change speed inductive-resonance transfer for donor-acceptor pairs that forming with nanoglobule different geometric configuration. Using the statistical theory of macromolecules presents a description of the dependence of distribution density of links of the macromolecules on the surface of spherical nanoparticle. The peculiarities of conformational rearrangements and equilibrium structure of homogeneous polypeptides adsorbed on the surface of spherical gold nanoparticles with radius of 4nm were investigated using molecular dynamics (MD). Homogeneous polypeptides consisting of100 and 500proteinogenic amino acid residues were considered. As a result of molecular-dynamic modeling were obtained equilibrium conformational structures uncharged homogeneous polypeptides adsorbed to the surface of the spherical gold nanoparticle. Radial distribution of the average atomic concentration of polypeptides on the surface of gold nanoparticles are calculated on a 5-produced model calculations, estimated a mean square deviation. Approximation of the radial distribution of the average atomic concentration of the polypeptides was produced by the formulas obtained by the methods of the statistical theory for the distribution of the density of links of macrochain on the surface of spherical nanoparticle. Numerical values of the parameters of the approximation curves of the average radial distribution of atoms of polypeptides on the surface of spherical gold nanoparticles are presented in the table. The results can be used to correctly describe the features of the kinetics of molecular reactions in near-surface areas of gold nanoparticles coated with a macromolecular chain.

DIFFUSION CONTROLLED REACTION KINETICS IN NEAR-SURFACE SHELL OF FULLERENE-TUBULENE NANOPARTICLE WITH ADSORBED MACROMOLECULAR CHAIN [№ 9 ' 2013]
A mathematical model of the electronic excitation cross-annihilation kinetics of oxygen molecules and organic dyes, connected with macromolecule linkers adsorbed on a fullerene or carbon nanotube (tubulene) surface in a solution is proposed. The model taken into account a non-homogeneous character of the radial distribution of polymeric chain linkers forming like profile of oxygen singlet excitations generation centers and furthermore diffusion relaxation features of its density in the near-surface zone of the different curvature radius. Expressions are produced for the time — dependent signal of annihilation delayed fluorescence of dye molecules and they are different for the spherical and tubular nanoparticle. The oxygen molecules thermal diffusion which obtained by the formation of a non-homogeneous temperature field in the near-surface layer was taken into account. The estimation of the thermal diffusion effect value is made and its influence on the long-time luminescence kinetics of dye molecules connected with polymeric chains adsorbed on fullerene/tubulene kernels is obtained.

KINETICS OF THE QUASI-STATIC QUENCHING OF EXCITED CENTERS, THE SURFACE LAYER OF SEGMENTS OF MACROMOLECULAR CHAINS IN NANOPORES AND IN THE VICINITY OF NANOPARTICLES [№ 5 ' 2010]
We studied the kinetics of the radiationless transfer of electronic excitation energy between molecules, located inside the spherical nanopolosti filled macromolecular chains. The case was studied where the donor centers are located on the surface of the cavity, and the acceptor molecules attached to the chain segments. We built a mathematical model that takes into account the random variation of the conformation of macromolecules, which lead to modulation of the radius of the donor-acceptor pair, supported by molecular dynamic calculations. We studied also the cases of systems "reverse geometry" in the deployment of macrochains and reagents on the outer surface of spherical and cylindrical nanoparticles.

PLACEMENT OF LYSOZYME FRAGMENTS IN CYLINDRICAL PORE MADE OF ALUMINUM OXIDE [№ 4 ' 2009]
Through molecular dynamics method, spatial distribution of polypeptide chain links was identified that was placed inside cylindrical aluminum oxide pore in protein fragments (70amino-acid residues of lysozyme). Modeling of kinetics for the transfer of macrochain to equilibrium conformation was conducted at the temporary stage up to 300picoseconds from the ordered start configuration of protein fragment under constant temperatures of 400, 800. Numerical values were determined for the parameters used for approximation of the polypeptide links distribution density curves along the normal line coordinate towards the pore bottom and by radial dependence of the links concentration in cylindrical pore. The data obtained may be used for description of biomolecular reactions kinetics in structured systems.

THEORETICAL BASES OF BANK SYSTEM AND REGIONAL ECONOMY INTERACTION [№ 10 ' 2006]
The processes of bank system and regional sector interaction are necessary factor of market economy forming and important element of structural economic reconstruction. Suppositions of economy increase and its stable development guarantee originate only with the advent of conditions for effective collaboration and common understanding.
