01.00.00 Physical-mathematical sciences
DescriptionThe study of the thermo-physical properties of liquids gives an opportunity of qualitative and quantitative evaluation of condensed matter theory, phase transitions and critical phenomena. To forecast the thermo-dynamic properties of liquid natural hydrocarbons one must know the basic heat-physical characteristics in a wide range of condition parameters. We have researched specific isobaric thermal heat capacity of gas condensates of Oposhnyanskoye, Solokhovskoye, Bukharskoye, Rybalskoye, Stavropolskoye, Schebelinskoye and Yubileinoye deposits theoretically and experimentally. These substances were in liquid phase on pseudo-critical isobar in the range of temperatures from minus 40 till 100 °C. In the article the findings of the investigation are presented. The mean relative experimental error doesn’t exceed ± 1.5 %, with reliability 0.95. The universal equation expressing specific isobaric thermal heat capacity as the function of temperature and molar mass has been obtained. It describes specific isobaric thermal heat capacity on pseudo-critical isobar for investigated natural hydrocarbons with the mean relative error, which does not exceed ± 1.65 %. The use of the equation for the calculation of specific isobaric thermal heat capacity of the substances of other deposits is recommended

ANALYSIS AND FUTURE DEVELOPMENT OF INNOVATIVE ACTIVITY IN THE KRASNODAR REGION
DescriptionEffective management of innovation processes is an important prerequisite for economic growth and competitiveness of the country and can be achieved with the active participation of the state in the field of innovation system. The structural elements of the innovation system are the government, business, education and science, which interact on the basis of the legal framework of innovation. Innovative development is the consistent implementation of measures for the implementation of innovative activities by all actors of the innovation system with the involvement of the all major spheres of life and to ensure the effective interaction of all elements of the innovation system. Currently, the priority development of the Russian economy is a shift from raw materials to innovative. The Krasnodar region is among the regions with the most developed innovative potential. The region is actively developing a legislative framework aimed at regulating the innovation processes operate research and development centers, is strongly supported by local authorities. This article has identified the priority sectors for the development of the edge of innovation processes, analysis of the main indicators of innovation activity, defined constraints of innovation, defined terms of investment attractiveness of the Kuban and the development of innovative tools environment

About fragile fracture of solids in the formation of a "narrow" isolated defect
01.00.00 Physical-mathematical sciences
DescriptionWe obtain a macroscopic criterion of fragile fracture (limit curve) when creating an isolated defect in the form of “narrow” undercut, when conformal mapping of the exterior of a unit circle on the plane with de-effect in the form of a recess defined by cut fiber-foam series. It is shown that in this case, the limit curve has the form identical to the case when the defect is set to "narrow" ellipse. The same crack oriented along either the compressive stress or tensile perpendicular stress. From here, we can suggest that the shape and geometric properties of a sufficiently "narrow" defect do not affect the values of the critical loads required to start its distribution

THE IMPORT SUBSTITUTION AS A TRANSITION TO EXPORT ORIENTATION APC
DescriptionThe goals of import substitution, import data and export resource features of the agrarian economy, through which you can generate significant competitive advantage are discussed. It is noted that the flight of the capital abroad creates jobs not for our economy, but for our competitors, that low interest rates on loans create obvious unequal starting opportunities throughout the domestic business. As a result the cost of imported food in value-chain terms reached in our country an enormous rate of $45 billion and that government realized the need of strengthening of food security, transferring of production of traditional kinds of products which form the basis of consumption of the population in our country, to the domestic market. It is noted that we need temporary moderate state protectionism and protection of the domestic market with the aim of modernizing the economy, attracting investors in the important field of production with high risks. The main problems and solutions that will help to further successful implementation of this strategy in the sectors of our economy are highlighted. It is proposed to establish a network of specialized information centers to support import substitution with a database of technological profiles of organizations. The author block diagram of the information support and import substitution is given. The importance of federal and regional programs functioning in the import substitution is noted. The author's plan for their implementation is given . Predictive modeling of short-term, medium-term and long-term positive and negative consequences of import substitution and export orientation are implemented. The authors stress that the substitution should be seen as a transition to export orientation of the agricultural economy.

01.00.00 Physical-mathematical sciences
DescriptionThe article examines the historical aspect of the appearance of the concept of the photon, which was introduced through the works of Planck, Einstein, Compton, Lewis. It is noted that the photon has both corpuscular characteristics (momentum, mass, energy) and wave (frequency, wavelength), which are interconnected. Thus, the photon has dual properties – of a particle and a wave. The article deals with the analysis described in the literature of the photon model proposed by S.M. Polyakov and O.S. Polyakova, F.M. Konarevym-Krauzerom, V.G.Kozlovym and S.I. Chervyakov, as well as with their advantages and disadvantages. A version of the model in the form of a photon of two identical but oppositely charged halfmass, which simultaneously perform translational, rotational and vibrational motion was suggested. We have shown derivation of the amplitude of vibration of the two half-mass photon connected with simple relation with wavelength, described with this photon. On this basis, it is concluded that the state of a photon is characterized by a rotational movement of its oppositely charged half-stuff, which radius (r) is the amplitude of the oscillation process of each of the half-mass, and described by oppositely charged half-mass circumference length S in expanded form in a result of the progressive movement is the length wave l. This work displays the wave equation describing the motion of photons in the form of a standing wave which is a complete analog-independent Schrödinger equation for the motion of an electron in a hydrogen atom

THE DEFORMATION EFFECT OF VM SLIDER MULTI COMPLEX MACHINE SERIES ON PRECISION MACHINING
DescriptionThe article is devoted to the problems of increasing the economic growth of the Russian Federation, the development of high-tech knowledge-intensive manufacturing industries on the basis of a fundamentally new technological order, new unmanned technologies. The measures to improve the accuracy of manufacturing of complex and large-sized parts. Currently, the technical level of many sectors of the economy is largely determined by the level of production of means of production. The basis of these means is the machine tool industry. On the basis of machine tool development we handle a comprehensive mechanization and automation of production processes in industry, construction, agriculture, transport and other industries. We completed a comprehensive analysis of the errors affecting the manufacturing precision parts. The activities for improving the accuracy of manufacture based on VM 32 multi-machine complex series were proposed. We made the analysis of the cutting forces influence and the cross-sectional shape of the slide on its deformation for various types of processing. We determined the optimal shape of the cross section of the slider to increase stiffness and reduce deformation of the slide in metal cutting

THE MATHEMATICALLY BASED CHOISE OF VISCOELASTIC IN SHUNT GLAUCOMA SURGERY
DescriptionThe dramatic lowering of intraocular pressure (hypotony) is developing during glaucomatous surgery due to the formation of the new aqueous humor outflow. The calculations of the flow in the fluid balance parameters have shown, that for the normal intraocular pressure maintenance in the postoperative period the fluid flow out of the anterior chamber should not exceed 0,04 microliter in minute. The intensity of the aqueous humor outflow through the shunts with different parameters does not depend on the shunt length. The shunt with the inner hole radius 0,025 mm is the most safe as it provide the less outflow. The experimental comparative study of the static viscosity of the most widely used viscoelastics in ophthalmological surgery was carried out. It was stated that used in eye surgery viscoelastics on the basis of 1%, 2% and 3% sodium hyaluronate possess the viscosity, that differs in 10 and 100 times and has significant influence on the flow intensity out of the anterior chamber when the new outflow tracts are formed. The mathematically based choice of the most optimal relationship between the viscoelastics physical parameters and the inner hole size of the shunt type glaucoma drainage devices was established. Shunt with the inner hole radius 0,05 mm and simultaneous use of 2% and 3% sodium hyaluronate solution is the most safe for the maintenance of the eye tonus during the first 5 days after glaucoma surgery. The presented correlation allows to increase the safety of the surgical treatment of the patients with the refractory glaucoma
