Abstract
Perfection of machinery and technology for the processing of secondary raw materials of the meat industry is a very urgent task. One of the most important methods in the processing of blood of cattle is the effect of low temperatures, used both for preserving blood by freezing, and for its concentration by the method of freezing moisture. In this regard, the article examines the process of cooling the blood of cattle, which allows the most complete assessment of processes and phenomena occurring in the blood under the influence of low temperature. The features of studying the process of temperature reduction based on the main provisions of thermal analysis are considered. As a result of the experiment, the dependences reflecting the nature of the temperature change in the blood sample of cattle and the reference element have been obtained, allowing one to accurately record the features of the phase phenomena observed in this biotechnological environment. It is shown that the crystallization of moisture in the blood, which is a complex multicomponent solution, is due to the presence of eutectic compounds that arise when the temperature is lowered and water is released in the form of pure ice. Guided by the obtained temperature dependences, we obtained informative data on the necessary energy potential for the realization of cooling and freezing processes. The features of the mechanism of ice freezing in the blood under investigation from the point of view of the molecular-kinetic theory of molecular motion are explained. The carried out researches have allowed to define activation energy of processes of crystallization of a moisture in investigated blood of large horned livestock.

Abstract
The technological process of cereals production used in the production of feed stuff, which includes the following basic steps: grain moistening; binning of moistened grain for redistribution of moisture in the bulk of kernel; steaming of moistened grain; rolling of steamed grain; drying and cooling of flakes – is developed. In the production of flakes from scoured barley and oat grain before feeding to the rolling line film removal from the grain of these crops and the separation of the husks is carried out by one the existing methods: the method of grinding, followed by sifting and eventilation of films from tail fractions or a method of peeling on special machines with a separation of films. Wet-heat treatment of grain, followed by rolling helps to improve taste and palatability of feed, improves the nutritional value of carbohydrate and protein complexes, reduces the exertion of the body to digest food nutrients, allows to inactivate antinutritional substances and free the grain from the pathogenic and other microorganisms. In the duration of rolling process splitting of complex carbohydrates occurs, starch loses its original structure and is easier exposed to enzymes. The dried and cooled flakes have satisfactory flowability, do not set up. Humidity of flakes is not more than 14%, the temperature is not more than 10 °C above the ambient temperature, bulk density is 350–400 kg/m3. Developed set of equipment allows producing cereal flakes, the use of which in feed stuff and rations of young cattle and pigs increases the productivity of animals by 15–20% while reducing feed costs by 12–15%. Cereal flakes are used in the manufacture of complete feed for piglets (pigs at the age of 10 to 60 days), feed concentrates for pigs under the age of 4 months, the calves under the age of 115 days, high-producing cows, sporting and trained horses and lactating mares.

Abstract
Purification of crude unrefined sunflower oil along with the removal of primary oxidation products is an urgent task to remove the solid constituents formed during the processing of sunflower seeds. All of them irrespective of the chemical composition negatively affect the quality of the food product and, over time, saturate the oil with coagulants that affect its organoleptic and physico-mechanical characteristics. The problem of cleaning unrefined sunflower oil by filtration with the use of vibroacoustic action is considered. The calculation scheme of the process is given, and an experimental setup has been developed that makes it possible to vary the angle of inclination of the filter element. The research of sunflower oil filtration in the field of vibroacoustic impact is carried out. In the study, a decision was made to expand the energy effects to create a cumulative system in the liquid medium that improves the hydrodynamic situation at the scale of the oil purification plant. It is established that the process speed can be intensified by creating additional microflows that provide an active influence on the motion of liquid, gas and solid particles. The results are obtained, which testify to the effectiveness of the use of vibroacoustic effects during the filtration of sunflower oil.

Abstract
For the baking of baked goods in order to save fats, different types of endorsement and protein-fatty emulsions which are used as ingredients in goods and for the protection of metal moulds from burning. Usually emulsion is prepared on bakery enterprises by National State Standard Р 51785–2001, involving mechanical beating up of ingredients. The authors suggested and studied the way of manufacturing of more stable food protein-fatty emulsions using ultrasonic transmitter with rigid neodymium magnets on its thickener. As ingredients, there were applied curd whey diluted with water, unpurified sunflower oil and sunflower phosphatides. Ratio of whey and water is 1:7. Physical effects of ultrasound and field of magnets in contact layer of liquid ingredients being dispersed have increased the viscosity and dispersion of protein-fatty emulsions. Hypothesis of increase of stability and sterility of protein-fatty emulsion by the selection of parameters of magnetic field and power of ultrasound transmitter is confirmed experimentally. Microscopic analysis shows high degree of homogeneity of emulsion under the time of processing 3-4 minutes and intensity of ultrasound 2 W/cm2, that is energetically profitable. There was revealed synergism of influence of physical effects of ultrasound and magnetic field on the durability and steadiness of emulsion to mechanical and temperature effect and also cidal effect, prolonging terms of product using. Manufacture of emulsions by the declared way using the ultrasound and magnetic field of constant neodymium magnets decreases number of injected elements-emulsifiers by 3-4 times or excludes their use at all. Existing piezoelectric ultrasound units as well as neodymium magnets have small sizes and low energy consumption, easily built into the line of continuous manufacture of emulsion for the bread production. Such emulsions are less demanding to the storage and transportation.

Abstract
The article gives a mathematical description of the process of pressing safflower seeds in an ultrasonic field in the form of a regression equation found by static methods on the basis of experiments and described by a polynomial of the second degree. As the main factors influencing the efficiency of the process, the ultrasound frequency, the amplitude of the ultrasound, the pressure and the press created in the green chamber were selected. And as a criterion for assessing the effect of the selected parameters, the residual oil content of the cake is used. To assess the adequacy of the mathematical model, the variance analysis (ANOVA) of the experiment in the Design Expert v. 10 and the regression equation is obtained, the analysis of which allowed us to identify the factors that most influenced the process under consideration. Found that when the pressure in the press to a value higher than 14 MPa, a further increase in efficiency was observed together with increased values as the ultrasound frequency and its amplitude. The maximum and most effective value residual oil content in oil cake obtained in the frequency 35-40 Hz and amplitude of more than 40 mm and the pressure in the press from 10 to 11 MPa. which are obviously directly dependent on the behavior of grain and movement of its internal parts during the supply of the ultrasound. Graphical interpretation of the equation is represented by curves of equal values and response surfaces for input parameters. A numerical and graphical optimization procedure is also proposed to predict the optimal level of input factors and to obtain the maximum yield of oil relative to the mass of the original feed. To test the adequacy of the model, the results of a number of parallel experiments are presented that fall within the calculated confidence intervals for all quality criteria.

Abstract
As a result of research and analysis of kinetic dependencies of the pulsed radiation-convective drying process of potato slices under stationary conditions, a step-by-step regime for drying root crops was developed. Potatoes slices are subjected by combined radiation-convective drying. Moreover, the heating of the potato is carried out by infra-red rays with a wavelength in the range 1.16–1.65 mkm and a heat flux density of 2.69-5.44 kW/m2 with simultaneous convective air blowing for water vapor evaporated from the product removal with initial temperature of the environment 293 K. Stepwise regime essence is as follows. Total drying process duration is divided into a certain number of stages. Durations of each time step was determined experimentally as a result of drying and drying rate curves analysis potato tubers stationary drying regimes. At each stage a fixed value of product temperature and air speed is selected. At the graphical dependencies analysis it is possible to distinguish three drying periods: heating, constant and decreasing drying rate. At the first stage potato slices 1.5 mm thick are heated by infrared rays up to 318 K temperature with simultaneous airflow with speed of 1.6 m/s for 6 minutes; at the second stage-up to 323 K temperature with air speed 1.2 m/s for 18 minutes; at the third stage-up to 328 K temperature and with air speed 0.7 m/s for 12 minutes. Later dried to a final 12% humidity potato slices are processed with flavoring (spices).

Abstract
With the purpose of scientific and economic feasibility of the process of accelerated manufacturing of pasta with a high concentration of animal protein and vital nutrients for Arctic workers was conducted a study on the modernization of production equipment, and a method of the production of pasta with increased nutritional value was developed. During the study a number of inconsistencies in the implementation process of drying pasta in the prior art ovens was revealed. The increased amount of ground meat and beef liver (30%) in the composition of such products requires drying at elevated temperatures in order to eliminate acidity and microbial spoilage, which led to loss of shape, strength and cracking. We have developed a compact technical device based on Angelo Po combi steamer with integrated electronic ultrasonic transmitter UZAGS-0.3/22-D with an intensity of about 140 dB for accelerated drying of pasta with high-protein additives. The proposed technology allows to accelerate the production of finished products by 24–26%, while reducing energy consumption by 8–11%.

Abstract
In this study, methods for intensifying micro- and ultrafiltration processes by controlling the concentration-polarization effect are considered and studied. The negative effect of concentration polarization on the process of separation of the filtered liquid and on the membrane surface is described (due to the increase in concentration, the selectivity and specific productivity of the membrane surface decrease). The physical picture of the flowing phenomena in a flat membrane channel with known geometric dimensions is considered, four sections with different effects on the filtration process are identified. The equation of material balance is analyzed by introducing boundary conditions into the criterion equation of material balance, with the aim of finding opportunities for mass transfer. It is revealed that the mass transfer coefficient km decreases, due to the growth of the thickness of the boundary layer. The main parameters significantly influencing the process of microfiltration are the flow rates G of the initial solution, the mass transfer coefficient km, and with decreasing km decreases and G. The analysis of theoretical and experimental data is carried out showing that the decisive role in the course of the microfiltration process is played by the motion regime of the initial solution, Physical-chemical properties, geometry of the membrane channel. The prospects for using the pulsating field in bioreactors and the need for a conceptual approach for the development of promising membrane devices are grounded. The need to create membranes of complex geometric shapes with the possibility of placing turbulent devices in them and the possibility of moving them relative to each other is considered, creating channels of variable cross-section, which will lead to the appearance of a sufficient number of possibilities for creating hydrodynamic instabilities of various intensities. The article touches upon the application of pulsation regimes of destruction or loosening of the polarization layer by means of reciprocating motion of the concentrate, periodic membrane regeneration by tangential pulsating flow or by using reverse pumping.

Abstract
In this paper, we propose a new scheme of a highly efficient line for preparing safflower grains for processing consisting of an air-sieve separator, a magnetic separator, an ovary, a puppet, and a stone picker. The new after vortex separator is a vibroseparator for separating the products close in physical properties, grinding Machine with a duo-aspirator, a photoseparator and a device for moisture-thermal treatment. Advantages of the proposed line for preparation of safflower grain for processing are that an additional plant in front of the photocarerator of the grinding machine and duo-espirator allows the crest to separate and remove or refine the shell of the seed in the form of a shell layer for more efficient subsequent spectral point analysis, which determines the grain composition for the purpose of sorting it On the basis of chemical composition and color in the photo separator, and sequential placement after the stone separator of a vibro separator for separation of products close in physical properties, a grinding machine with a duo-aspirator, a photoseparator and a device for moisture-thermal treatment, provides an intensification of the technological process of efficient separation of safflower from impurities and its preparation for further processing and Due to the rational layout of equipment.A highly efficient photocell separator is also provided, the advantages of which are that the installation of a storage and vibrating feeder in relation to the slanting tray from the back side and the execution of a smooth curved transition to the vibrating feeder in the upper part of the pitcher allows improving the separation of grain products by reducing the amplitude of grain oscillations, Caused by a rebound from the surface of the tray during the loading of the sorted material from the vibrating feeder.

Abstract
The residue in sunflower oil is a dispersed phase consisting of particulate products grinding sunflower seeds in the form of particles of the pulp, oil cake, meal, residual quantities of metals, pesticides. In the recycling process they are in the oil in suspension and negatively affect its quality. For research an experimental setup was developed allowing to change the angle of inclination of the filter element. The regularities of filtration were determined without preliminary purification of sunflower oil by centrifugation and after centrifugation. It is established, the contamination of centrifuged oil in the initial period is 14.6 times lower. After 10 minutes of treatment, it decreases by 62%, after 20 minutes – by 79.4%. With a 30-minute treatment, particles of 0.005-0.1 mm in size are removed to 90%, which is approximated to the refined oil in terms of contamination. The influence of vibration-acoustic action on sunflower oil during its filtration is shown. At the last stage of production, the peroxide index is reduced to 2-3 moles of active oxygen, and after 3 months of storage – from 11.8 to 7.7, which according to GOST corresponds to the highest-grade oil. The regularities of the filtration without pre-treatment of sunflower oil by centrifugation and after centrifugation. Shows the effect of vibroacoustic exposure on sunflower oil when filtering.

Abstract
Styrene synthesis process occurring in a two-stage continuous adiabatic reactor is a complex chemical engineering system. It is characterized by indeterminacy, nonstationarity and occurs in permanent uncontrolled disturbances. Therefore, the task of developing the predictive control system of the main product concentration of the dehydrogenation reaction - styrene to maintain this value within a predetermined range throughout the period of operation is important. This solution is impossible without the development of the process model on the basis of the kinetic revised scheme, taking into account the drop of the reactor catalytic bed activity due to coke formation on the surface. The article justifies and proposes: the drop changes dependence of catalyst bed activity as a time of reactor block operation function and improved model of chemical reactions kinetics. The synthesized mathematical model of the process is a system of ordinary differential equations and allows you: to calculate the concentration profiles of reaction mixture components during the passage of the charge through the adiabatic reactor stage, to determine the contact gas composition at the outlet of the reactor stages throughout the cycle of catalytic system, taking into account temperature changes and drop of the catalyst bed activity. The compensation of the decreased catalyst bed activity is carried out by raising the temperature in the reactor block for the duration of the operation. The estimation of the values of chemical reactions rate constants, as well as the calculation and analysis of the main and by-products concentrations of dehydrogenation reactions at the outlet of the reactor plant is curried out. Simulation results show that the change of temperature of the reactor, carried out by the exponential law considering deactivation of the catalyst bed allows the yield in a given range of technological regulations throughout the operation cycle of the reactor block.

Abstract
The brief presentation of the method of fast expansions is given to solve nonlinear differential equations. Application  rules of the operator of fast expansions are specified for solving differential equations. According to the method of fast expansions, an unknown function can be represented as the sum of the boundary function and Fourier series sines and cosines for one variable. The special construction of the boundary functions leads to reasonably fast convergence of the Fourier series, so that for engineering calculations, it is sufficient to consider only the first three members. The method is applicable both to linear and nonlinear integro-differential systems. By means of applying the method of fast expansions to nonlinear Navier-Stokes equations the problem is reduced to a closed system of ordinary differential equations, which solution doesn't represent special difficulties. We can reapply the method of fast expansions to the resulting system of differential equations and reduce the original problem to a system of algebraic equations. If the problem is n-dimensional, then after n-fold application of the method of fast expansions the problem will be reduced to a closed algebraic system. Finally, we obtain an analytic-form solution of complicated boundary value problem in partial derivatives. The flow of an incompressible viscous fluid of Navier–Stokes is considered in a curvilinear pipe. The problem is reduced to solving a closed system of ordinary differential equations with boundary conditions by the method of fast expansions. The article considers peculiarities of finding the coefficients of boundary functions and Fourier coefficients for the zero-order and first-order operators of fast expansions. Obtaining the analytic-form solution is of great interest, because it allows to analyze and to investigate the influence of various factors on the properties of the viscous fluid in specific cases.

Abstract
Thermoplastic elastomers are a promising class of polymeric materials whose properties are close to those of conventional rubbers. Thermoplastic elastomers are recycled by high-performance methods used to process plastics in contrast to ordinary rubbers. Also thermoplastic elastomers exclude the stage of vulcanization from the technological scheme and they are capable of multiple processing. The problem of modeling of the kinetics of the crosslinking process in the preparation of a thermal elastoplast with a treelike structures was formulated and solved. The polyfunctional coupling agent used as crosslinking agent for crosslinking of diblock to produce thermoplastic elastomers with a treelike structures. A kinetic scheme of the coupling process is proposed. It based on the available experimental data on the molecular weight distribution of thermoplastic elastomers and the analysis of various combinations of polymer molecules. The scheme takes into account the possibility of attaching the active diblock to each functional group of the combining agent molecule of different structures. The mathematical model of the process taking place in the reactor of an ideal mixing of a periodic action is represented of the system in the form of differential equations. Modeling the process, it is assumed that the rate of the coupling reaction depends on the mobility of the molecules which enter into the reaction. The sum of the squares of the discrepancy of experimentally determined and theoretically predicted concentrations of thermoplastic elastomers of each structure is adopted as an optimality criterion for solving the problem of parametric identification. The computational experiment showed that the combining agent reacts with the active diblock mainly in two and three functional groups. The synthesized model allows to evaluate the concentration of the coupling agent, polystyrene-polybutadiene-lithium and thermoplastic elastomer with different molecular weight in a continuous time domain. The relative error in the results is 9.3%. The analysis results obtained allows us to conclude that the proposed model qualitatively correctly describes the coupling process.

Abstract
The key component of parallel computing efficiency is the structure of data exchange between computing nodes. It is necessary to reduce the latency of data exchange to improve the efficiency of parallel computing. A B+2R algorithm for overlapping delays in the data exchange was offered for this purpose. Existing works do not offer a method for selecting the additionally transmitted data layer count R. We introduce the models of all systems affecting the parallel calculation time. It makes possible to apply the analytical optimization. We introduce a data transmission network and a parallel computing application models. We consider the cell calculation time is a constant value. The cell calculation time depends on the specific calculation parameters. We introduce an estimate of the computation time. Computation time depends on the additionally transmitted data layers count. Further we introduce the derivative of computation time equation. We use lowest positive real roots of the cubic equation.  It’s possible that the final cubic equation hasn’t real positive roots. It’s mean that local structured grid calculation time is much bigger than network latency. In that case, it’s not recommended to use latency hiding schemes. Otherwise we recommend to use R equal to 1. Purpose of out research is to find optimal R. Optimal R value should lead to a calculation time equation minimum. The method proposed in the paper correspond to experimental result. Designed analytical model for B+2R algorithm makes possible to select optimal R value, which leads to the best calculation speedup.

Abstract
The model of passage of vessels through a section of the waterway is considered, which independently determines the order of passage of vessels with limited capacity of sections of the track. Such a model will consist of a number of standard algorithmic networks. When composing the schedule in the model, the following preference rules were used: first-come-first-served (that is, if the ship occupied the workplace, this decision is not canceled); The rule of the shortest operation; For the swamps the priority of vessels going downstream (the direction of flow from the source to the drain). An algorithmic network that implements the search for an acceptable schedule must implement the following for conflicting operations: the operation that has started is not interrupted; If several operations simultaneously claim for one workplace (port, reach) and their number is greater than its throughput, then the conflict resolution is carried out in accordance with predefined preference rules or based on the user's decision; If the operation is waiting for the release of the workplace, it does not occupy the resource; The resource is returned immediately after the operation is completed. The considered design of algorithmic networks allows to resolve the conflict, with a simultaneous resource request, to take the resource once, remember that it was received and return it after the end of the operation, then the resource receives a contra-controlling operation for execution. However, the use of this design introduces redundancy into the model, even if it is used only for conflicting operations. The model is presented in the language of algorithmic networks and is implemented in the system of modeling automation KOGNITRON.

Abstract
Developed out express Sorption-colorimetric methods for the determination of iron in water, based on the sorption concentration of detecting component of the solution impregnated in the polyurethane foam, the formation on the surface of a colored compound and then its definition in the sorbent matrix by measuring color intensity or chromaticity characteristics. The first method is based on determining the agitation of the sample solution with a tablet impregnated with PPU known mass, from which the air bubbles are removed, the second dynamic – by sampling by suction solution in the analytical cartridge impregnated with PPU. Discoloration polyurethane indicates the presence of iron (III) in water, and its content was determined by comparing the color intensity of foam tablets previously prepared color chart or chromaticity characteristics comparing analyte and standard solutions. The conditions of sorption-photometric analysis: the concentration of the photometric reagent impregnated in the foam, the degree of loading it impregnant, the phases of contact, the acidity of the environment. When using analytical cartridges lower limit of detection is 2 times higher, and the measurement error to 3.5% lower than with the tablets. The proposed test methods using polyurethane enable to carry out the analysis of wash water and the total flow of galvanizing plant before and after neutralization station “on the spot”, without the use of sophisticated instruments and highly skilled operator.

Abstract
The synthesis of prooxidants - carboxylates of variable valence metals (iron, copper and cobalt) was carried with the use of a mixture of fatty acids with an acid number of 100-120 mg KOH / g, separated from the soapstock, which is a liquid waste of oil- and fatproduction. Carboxylates of variable valency metals were synthesized in a high-energy ultrasound field using a generator USG13-0.1 / 22. Mixed thermal and ultrasound effects contribute to an increase in the yield of metal carboxylates. The maximum yield of prooxidates was over 84% (by weight).When carrying out the synthesis of carboxylates of metals of variable valence, ion activity was revealed in the exchange reactions with sodium salts on the basis of a mixture of fatty acids in the following order: Co2+ >Cu2+ >Fe2+. The synthesis of carboxylates of variable valence metals is a multifactor system and depends on temperature regimes, metal activity, viscosity and structural characteristics of a fatty acids mixture. The formation of metal carboxylates was carried out in a water-alcohol medium at a high rate for the heterogeneous systems, which are the exchange reactions between strong alkali salts and carbon acids. It should be noted that an increase in the synthesis temperature above 60 ° C with simultaneous ultrasound exposure reduced the yield of products and influenced the quality composition of the carboxylates of metals of variable valency.We should also take into account that ultrasound impact allows to obtain a prooxidant of the required dispersity and it is extremely important in the production of multifunctional and targeted additives. The use of ultrasound fields of high intensity in the synthesis of carboxylates of metals of variable valence is preferable in a less viscous medium due to the better ultrasound spread

Abstract
The quantitative and qualitative analysis of the import additives d2W (England) and Tosaf group corporation (Israel) in the form of composite materials containing prooxidants was carried out on a S8 Tiger X-ray fluorescence spectrometer. Analysis of the elemental composition of additives used in the production of biodegradable polymers showed a different approach to foreign manufacturers, both in composition and in difference of the polymer basis. It is determined that the catalytic ability of both the additive d2W and the additive Tosaf is characterized by the presence of a wide range of elements in the form of metals, including variable valence, while the presence of a limited number of nonmetallic elements is noted. Additive d2W contains the following active elements,% (by mass): manganese – 0.16; strontium – 0.014; iron – 0.01; calcium – 17.15; magnesium – 0.13. The significant content of calcium d2W in the catalyst (17.15%), probably in the form of oxide, provides a significant developed surface of the additive. Additives Tosaf lot No. 1 as a whole contains the following active elements,% (by mass): cobalt – 1.18; Zinc 0.6 and iron 0.024, with a small amount of iron, potassium, calcium, chlorine, phosphorus, silicon, zinc and copper. A slightly different elemental composition in batch No. 2 for the content of cobalt is 1.07% (by weight) and iron – 0.033% (wt.) The variety of a wide range of elements that are characterized by different acid-base and other physicochemical properties, That secondary raw materials were used to produce the corresponding prooxidants. It should be noted that, as a polymeric matrix of metal carboxylate additives, polyolefins are presumably used to better combine and distribute the prooxidants when the synthetic polymer is modified.

Abstract
The rheological behavior of additives - pro-oxidants, representing a polymer matrix including iron carboxylates is considered in the article. The additives of prooxidants based on: high-pressure polyethylene (PVD) of PVD 158030-020, secondary linear high-pressure polyethylene (LDPE) and secondary PVD with an iron carboxylate content of 5.0% (by weight) were used as the objects of the research. The study was carried out on a high-power capillary rheometer called Smart RHEO 1000 by the firm Ceast at a temperature of 130 to 190 °C using two capillaries with a diameter d = 1 mm and a length l = 5 and l = 30 mm, respectively, in the shear rate range from 100 to 300 s-1 with a step of 50 s-1. The study showed that for all investigated pro-oxidant additives, a linear dependence of the flow curves in double logarithmic coordinates is observed in the full velocity and temperature ranges. With increasing temperature, the dependence of the effective viscosity on the shear rate decreases synchronously, that is, in the double logarithmic coordinates, the flow curves are completely invariant with respect to the construction and the geometric parameters of the capillary irrespective of the form of the polymer matrix. The unstable flow regime was noted for the additives of prooxidants based on primary thermoplastics and occurred at a shear rate exceeding 250 s-1 and a temperature below 150 °C. For a longer capillary, the viscosity and shear stress efficiency indicators were reduced, the identity with the behavior of the primary thermoplastic was manifested, consistent with theoretical representations of the behavior of the macrochain under conditions of their formation on a longer forming tool.

Abstract
The study of thermal and mechano-thermal effects in the inert and air environment on the evolution of gas formations from high pressure polyethylene (LDPE) was carried out on a Smart RHEO 1000 capillary rheometer with the CeastView 5.94.4D software, using capillaries 5 mm in length and 1 mm in diameter . Study of composition Gas formations during the deformation of polyethylenes of different grades through the channel of a capillary viscometer. Which were characterized by structural characteristics, were carried out at shear rates close to production in the range from 50 to 300 s-1 at temperatures of 160, 190 and 220 ° C. The objects of the study were domestic thermoplastics of the following brands: LDPE 10803-020; LDPE 15803020; LPVD F-03020-S; HDPE 293-285-D, characterized by structural characteristics. It is established that the gasification during extrusion processing is promoted by the branching of polyethylene, while the degree of destruction processes increases with increasing temperature and depends on the reaction medium of the working volume of the equipment. Emerging critical shear stresses in the absence of oxidants and impurities contribute to mechano-destruction, accompanied by the formation of free radicals, which recombine to form a more branched structure of the polymer. In turn, the high temperature promotes degradation in the side parts of the polymer to form volatile products that are released from the reaction volume. It should be noted that the gassing due to thermal exposure is promoted by the air environment, but to a lesser extent than with mechano-thermal action. A smaller measure of the impact in the inertial medium is apparently associated with a limited access of oxidants to the destruction centers.

Abstract
The influence of modifying of elastomer compositions based on nitrile rubber in the medium of low molecular weight polyethylene oxide on resistance of rubbers to liquid aggressive mediawas studied. Standard hydrocarbon oils – oil ASTM №1 and ASTM №3, having a constant chemical composition and properties, were used as aggressive fluids. Resistance of elastomer compositions to standard oil was evaluated by change in weight, volume and relative compression set after keeping the samples in these oils at elevated temperatures. The influence of aggressive environment on the degree of swelling and the value of compression set of compositions modified in polyethylene oxides medium was established. It has been shown that the mass/volume of modified rubbers during aging in oil ASTM №1 reduced to a lesser degree compared to unmodified samples, which is probably due to the influence of low molecular weight polyethylene oxides for the formation of vulcanizates structure. At the same time exposure to oil ASTM №3 of elastomer compositions increases the degree of swelling of modified rubber more than unmodified, which can be due to destruction by the action of aggressive medium additional intermolecular bonds between macromolecules of polyethylene oxide and rubber, resulting in increased flexibility of the elastomeric matrix segments. It revealed that modification of rubbers in low molecular weightpolyethylene oxides facilitates preparation of rubber with low compression set after aging in standard oils at elevated temperatures.

Abstract
By the methods spectrophotometric methods was investigated complex formation of copper with 2,6-ditiolphenol and its derivatives (2,6-ditiol-4-methylphenol, 2,6-ditiol-4-ethylphenol and 2,6-ditiol-4-tert-buthylphenol) in the presence of heterocyclic diamines. As heterocyclic diamines phenantroline (Fen), batophenantroline and dipyridile were used. It was established, that mixedligand complex were formed in weak acidic medium (pHop=6,0-8,5). Maximum of light absorption observed at (=522–550 nm. Molar coefficient of light absorption was ( = (3.08–4.92)?104. The stoichiometry of complexes had been discovered using shift the equilibrium and relative yield methods. During the extraction of copper(II) complexes with ditiol-phenols with the presence of heterocyclic diamines there was discovered that there is no chlorophorm molecules in the composition of the extracted complexes. IR spectra shows that hydroxyl group is involved to the formation of a bond with the metal and that phenantroline is included in the composition of the copper complex. In the organic phase mixed-ligand complexes have the monomeric form and can’t polymerize; that fact can be proved by calculations. By dint of spectrophotometric, IR-spectroscopic, thermogravimetric experiments and some published data we were able to determine the structural formula of complexes. Also had been determined main spectrophotometric characteristics of copper(II) mixed-ligand complexes: pH of the beginning of the deposition, optimal pH, detection limit and sensivity. For separation and finding copper, we studied the effect of interfering foreign ions: alkali, alkaline earth and rare earth elements, as well as acid anions selected masking reagents. On the base of the results was offered photometric method for determination of copper in steel different trade-marks and in food. This method characterized by good reproduction (relatively standard deviation no more 0.05) and low limit of discovery.

Abstract
One of the most important characteristics affecting the technological and consumer’s properties of tobacco, tobacco products, including tobacco for hookah, is humidity. Methods for determining the moisture content in hookah tobacco do not exist. The review of literature on the existing methods for humidity determination of food and tobacco products has been carried. In order to adapt existing in tobacco industry methods for determining humidity in hookah tobacco their review has also been carried. The purpose of researches was studying the various drying regimes for obtaining objective information on humidity of tobacco for a hookah. Two temperature regimes of 95 °C and 105 °C with various drying duration has been studied. Statistical analysis of experimental data, confirming the accuracy of the experiments has been carried. It has discovered that curing duration at studies temperatures of hookah tobacco samples does not affect greatly the content determination, but temperature of curing affects greatly. Method of continuous drying at ambient temperature is considered to be the most accurate, and has been taken as a comparison. It was found that the experimental results of moisture content determination in hookah tobacco greatly differ from the comparison; this can be probably explained by the peculiarities of the composition of hookah tobacco. Hookah tobacco includes hot only tobacco particles but also honey, sugar beet molasses, volatile compounds (flavorings and glycerin). Glycerin is non-volatile at ambient temperature, but at higher temperatures it begins to evaporate rapidly. This mass loss of studied hookah tobacco samples caused by increased temperature considered to be water, so final result on water content determination is inaccurate. The obtained results are not final and further researches should de continued.

Abstract
The widespread use of bioflavonoids, due to their antimicrobial activity and antioxidant properties, necessitates their separate determination in a joint presence. It is noted that the total content of flavonoids, determined by different spectrophotometric methods in the same samples, differs and depends on the structure of the individual flavonoids that make up the samples. The paper presents the results of studies to determine the content of flavonoids in the fraction of the dry extract of shalfeeloid canthus (Cistus salviifolius), which has antimicrobial activity against bacteria of the genus Pseudomonas, which causes damage to protein-containing food products. Curing flavonoids by sequential extraction with aqueous alcohol solutions, filtering and dissolving the dry residue in isopropyl alcohol followed by passing through the gel layers. The following methods for the determination of flavonoids are considered: reaction with Folin-Chikalteu reagent (using quercetin as standard), reaction with aluminum chloride and 2,4-dinitrophenylhydrazine. When oxidized in alkaline medium by the Folin-Chikalteu reagent, which is the phospho-molybdotungstate heteropolycomplexes of flavonols, flavin-3-ol and flavones can be converted into quinoid compounds having absorption bands in the visible region of the spectrum. Only flavones and flavones having hydroxyl groups at positions 3 and 5 can interact with AlCl3. 2,4-dinitrophenylhydrazine only interacts with flavonols. The obtained calibration curves and structural formulas of flavonoids are given, which can be determined by the methods presented. It was found to contain flavonols 0.21 mg / mg, flavones 0.17 mg / mg and flavin-3-ol 0.06 mg/mg.

Abstract
Investigated the extent of adsorption removal of calcium carbonate pigments - products of conversion of the reducing substances in different conditions of the preceding limestone processing flow. Also carried out experiments on the influence of the conditions of conversion of the reducing substances in the process of lime treatment on the filtration characteristics of the solutions after the first carbonation. As the criterion was accepted the value of the filtration coefficient. Found that by subjecting the conversion of reducing substances in the process managed lime processing, it is necessary in the course of the subsequent carbonization to ensure maximum adsorption of the formed secondary products – it is possible to achieve a satisfactory filtration of the investigated solutions. It is shown that the largest absolute removal of the dyes obtained after high temperature lime treatment, however, the composition of the products of disintegration to a greater extent accumulate high molecular weight compounds which deteriorate the filtration performance of solutions. In the solutions after the combination of the lime treatment in the process of carbonization is achieved the maximum effect of adsorption with the minimum remaining shares of conversion products, including high-molecular substances, which favorably affect the parameters of the filtering. The combination possibilities of the model of purification of diffusion juice with warm-hot lime treatment is limited to receive the filtered juice in the processing of raw materials with a purity of beet juice 82 % or less, you need to enter a 3.5% Cao, which is unacceptable. To ensure sustainable results of the adsorption of conversion products reducing substances and satisfactory filtering carbonated solutions are to intensify the processes of combined lime processing diffusion juice at the optimum distribution of the reagent.

Abstract
Food safety and food raw materials is an important task which needs to be under government’s and public associations’ control, under enterprises which produce and sale them, and other economy departments. Nutrition is one of the most important factors influencing human health. To 70% alien substances of chemical and microbiological origin get into the human body with food. The heavy metals, nitrates, nitrites, pesticides, nitrosescomounds, mycotoxins, antibiotics, radionuclides and others are xenobiotics of chemical origin. The poultry products represented in commercial networks by poultry plants located in Saint-Petersburg and Leningrad region: “Roskar”, “Sinyavinskaya”, “North”, “Lebyazhye” were picked up for analysis. We used the bacteriological, virological, immunological, mycological, and statistical methods of research. Sanitary -hygienic or microbiological safety of food products was evaluated for the contenting of disease-causing (pathogenic) microorganisms such as bacteria groups, coliforms, Staphylococcus, Salmonella and etc. in them. The poultry products sold in commercial networks of St. Petersburg were picked up for analysis. After processing the statistical were revealed 6 nosological forms where the leading position has finding colibacillosis – 27%. The number of positive samples for streptococcosis – 18%, staphylococcus – 8%, aspergillosis–2.6%, salmonellosis – 1.8%, pasteurellosis–1.6 %. The microbiological control of food products which can be the sources of infections should be regular for providing inhabitants with harmless poultry products. It is necessary to adopt and to use the modern microbiological criteria of food safety that will allow to realize the monitoring of their conformity with sanitary norms. The results of these analysis shows that the quality of poultry products sold in commercial networks of Saint Petersburg and the Leningrad region meet the standards.

Abstract
According to the Principles of State Policy of the Russian Federation in the field of healthy nutrition for the period up to 2020 we set the task of expanding the range of specialized food for various population groups, in particular, enriched with vitamins and minerals. The range of sugar confectionery is constantly updated and expanded, increasing the scale of production. Note particularly the increase in consumer demand for bakery products with improved organoleptic properties, increased food and reduced energy value. Given the popularity of sugary confectionery products to the public, subject to foodstuffs enrichment of biologically active components can serve as caramel. Of particular interest are sugar confectionery suckable characterized pleasant taste and increased comfort of use, combined with the speed and completeness of release of active substances absorption. Earlier studies have shown that the molecule biologically active substances surrounded by sugar “glass”, as it were covered by an inert gas-tight shell, and are resistant chemical changes. Important advantages of this group of products are relatively large periods of storage and good portability, which expands the geographical possibilities of its use. However, the use of sucrose as a main flavor component and preservative, is an unfavorable factor for a healthy diet as a whole, and particularly for certain groups of the population for health. Therefore, when designing articles of caramel syrup containing as a sugar substitute, the authors suggested the use of polyols in combination with a sweetener vegetable isomalt and stevioside.

Abstract
It is known that in a sugar production, only about 80% of sucrose, extracted from the beet, is output as a commercial product. The rest is lost during the processing or remains in intermediates. The color of white sugar is mainly determined by the color of the returned to the first stage of crystallization of the brown sugars melt. An effective way to improve the quality of melt is affination of brown sugars. Coloring substances are preferably present in the film on the surface of sugar crystals. To improve the efficiency of affination experiments were carried out by layer-by-layer processing of the normalized crystal size with the saturated solution of white sugar. To evaluate the numerical characteristics of the color of the samples studied scanerometrical method followed by computer processing of images in RGB color mode was used. The studies suggest that the solution of the starting yellow sugar having visual yellow color intensively absorbs 450–480 nm of spectrum, so there is no blue component in the graphs. During the affination removing of coloring substances from the surface of crystals takes place changing the light absorption intensity. There is a bleaching of the samples at affination duration up to 3 minutes. Further 5–10 min treatment is accompanied by partial diffusion of colorants from mother liquor to the surface of crystals and improved chromaticity. Prolonged affination results in crystals abrasion; it is accompanied by unproductive energy consumption on the mixing process. The results obtained indicate that the effective removal of coloring substances occurs within 1–3 minutes of affination. In this case brown sugar chromaticity decreases from 625 to 130–230 units of optical density and mother liquor chromaticity is increased from 20 to 900–1600 units of optical density. The studies suggest that most of the coloring substances determining the chromaticity of yellow sugars is found in the film on the crystal surface and is easily removed by 3 min long affination. Method of determining of objects color characteristics in RGB system describes adequately the intermediates coloring of sugar production and can be used in research.

Abstract
The proteins, fats and carbohydrates received by the person traditionally from animal and vegetable sources don't cover all increasing needs of mankind any more today. At the same time proteins and fats of microorganisms with success can replace proteins and fats of a traditional origin. As protein producers microorganisms at the high content of protein in biomass and high growth rate of microorganisms have certain advantages. The present article is devoted to questions of numerical modeling of processes of cultivation of microorganisms. On the basis of the known model offered Mono in which saturation of growth rate of culture at increase in initial concentration of a substratum of S0 is considered the system of the differential equations describing the happening processes in that number before achievement of stationarity is written down. At the same time dependence of separate sizes, the systems entering the equations is insufficiently studied at change of parameters of process. The behavior of all system at violation of regulations is of interest or at unauthorized change of one of parameters. For studying of these questions numerical modeling is carried out and the basic picture of change of chemostate curves in these conditions is received

Abstract
In article process of the choice of strategy of development of the enterprise, entering into the integrated structure (IS) taking into account a possibility of obtaining additional competitive benefits by the enterprise from this occurrence is considered. The enterprises as a part of IS has to use a possibility of realization of effect of a synergy. In relation to the enterprise which is in IS, the synergy has not one concept, but three interrelations, different according to types, between the enterprises, namely: material, non-material and competitive. Such opinion of M. Porter shares most of the experts working in the sphere of strategic management. Realization of a synergy allows to improve overall performance not only IS (2 + 2 = 5) in general, but also and separately the enterprises entering IS. Overall performance of the enterprises improves thanks to obtaining additional competitive benefits by the enterprises in the form of decrease in expenses and differentiation of production that is realized by means of competitive strategy. Realization of effect of a synergy thanks to establishment of interrelations, as a rule, is followed also by increase in production of the enterprises entering IS that can be realized by means of growth strategy. Thus, it is desirable to develop strategy of development of the enterprise entering IS as the combined strategy consisting of two strategy: competitive and growth. The matrix of alternative strategy of development of the enterprise entering IS in the form of combinations competitive and strategy of growth, and also model of the choice of the similar combined strategy taking into account a possibility of obtaining additional competitive benefits by the enterprise is given in article. For an assessment of competitive advantages of the enterprise as a part of IS by means of ball estimates of experts the technique of a similar assessment, and a matrix of the arising interrelations of the enterprises in IS is given in article.

Abstract
The article addresses the problems of the conceptual apparatus of innovation as an economic category, the basic aspects of the innovation activities of the organization, conducted a historical analysis of the evolution of the concept of “innovation”. Previously, it was customary to assume that the process is driven by innovative organizations that develop and offer innovations, today; society has come to the realization of the consumer – the driving force of innovation development. All the analyzed theory can be combined approach to “innovation” consideration in terms of business benefits. The authors of the twentieth millennium write about innovation because of constant movement and change of the market economy, which leads to the speedy preparation of pre – businessman benefits by satisfying needs. Based on the foregoing, we believe that it is necessary to distinguish the concept of “invention” and “innovation”. Under the invention, we mean a new technical solution. An innovation is the initiation of the idea of innovation as a way out of intellectual activity, i. e., a new product, a new method, a new solution. By innovation author implies innovation, ie an invention or innovation after the commercialization process, demanded and implemented - introduction to the market, has successfully sold and which brought a profit. Treat innovation as the development process is not entirely correct, because not every development is innovation, development or process cannot be measured qualitatively, and it is impossible to talk about innovation as a result of the process will not be launched on the market and consumer demand there as the final result of the innovative activity of the enterprise. Because such an interpretation does not meet the scientific and practical needs of economic systems, the resolution of the identified contradictions, perhaps for the demarcation of the terms “innovation” and “innovation process”, although these concepts are very closely linked.

Abstract
The article provides a selection of methods for determining the feasibility of an investment-innovative project. Estimated indicators are identified analytically, on their basis a conclusion is made about the economic efficiency and feasibility of the project, which is the basis of its competitiveness. Such growth analytics is necessary, since the social and economic development of the country and the region largely depends on the investment climate, which is facilitated by the legislation of the Russian Federation (the Tax Code of the Russian Federation, the law of the Russian Federation on the regulation of investment activities, etc.). Since competitiveness is also determined by the economic feasibility and financial solvency of innovative projects, modern information and software, as well as the methodology for project appraisal and the corresponding order of their implementation, are needed. In the Russian Federation, a method is used to assess the efficiency of capital investments in capitalist countries, as well as the methodology of economic (competitive) analysis of investment-innovative projects. The basis of the method is that reimbursement of investments occurs in two economic forms: net profit and depreciation (net income). Of the numerous methods for assessing the feasibility of investment, the most often used along with discount methods (taking into account the factor of money changes over time), statistical methods with determining the payback period and the average rate of return on investment. Defined indicators: the net present value (NPV) and the internal rate of return (IRR). The methodology specified in the article is useful to the investor in order to rationalize investment flows, helps to achieve the maximum IRR. The implementation of the innovative project serves the competitiveness of the manufacturing enterprise by increasing the technical and technological levels of the products.

Abstract
In modern conditions of management it is necessary to develop a number of recommendations on the introduction of management accounting at state-owned enterprises that carry out revenue-generating activities or based on the right of economic management. It is necessary to apply the correct cost-accounting method for the production of products, works, services for a more rational calculation of the cost price. This will allow management personnel to receive timely objective information about their cost price, identify the feasibility of production and sales, justify the assortment, plan profits. The procedure for determining the cost price of the project products (works, services) in the theory and practice of the state enterprise of the Astrakhan region “Kasprybproekt” is investigated in the work. With the existing practice of planning in design organizations, the planned cost price of design and survey works for established cost items is planned in the cost estimate for production by the design organization as a whole and by the types of work: design, survey and others, without subdividing it by orders (projects). According to this, accounting of the actual costs for work in the design organizations is based. The study showed that the state enterprise of the Astrakhan region “Kasprybproyekt” performs different projects with different execution periods; therefore, it is advisable to use one method of calculating the cost price - job (order) costing method, and link it to the responsibility centers depending on the department of the performer. Based on the research of the used method to the cost price calculate of the project products (works, services) in the state enterprise of the Astrakhan region “Kasprybproekt”, it was proposed to use the job (order) costing method that allows to detail all the project costs without distorting the final financial result and optimize the project costs. If the calculation method is correctly determined, the design organization can reduce not only the labor costs, but also the actual project costs in order to increase its profitability.

Abstract
The development of company, as a rule, demands revision of the developed personnel management system, which is ceasing to answer over time her strategic objectives and not allowing satisfying the need for personnel. In article the experience of the “Rosizhiniring Energy” company, which optimized this system and has chosen the process-oriented approach for management is considered. Structure of article consists of introduction, the main part and the conclusion. In relation to a personnel management, system process management acquires special relevance because this system mentions all activities of the organization at all levels of hierarchy and directly or indirectly penetrates all business processes proceeding in this hierarchy. Strategy of “Rosizhiniring Energy” is focused on geographical expansion and opening of new separate divisions for implementation of projects. Full transition of a personnel management system and all organization to a process oriented management will allow divisions to observe certain standards of work, to provide qualitative feedback following the results, to use uniform criteria for evaluation of activity. Main methods of a research in this article – analysis of scientific literature, the methods of the theories of management and organization. The authors have made conclusions that modeling and the analysis of business processes of the organization will allow to structur the activity of the organization, to reveal strengths and zones of development according to the strategy of the organization, to define persons, which are responsible for business processes. It should be noted the economic efficiency of introduction of the process focused approach to a personnel management system of “Rosinzhiniring Energy” company: the personnel fluidity coefficient has decreased by 1.5–2 times; financial expenses within the budget of HR-department were reduced by 20% owing to increase in labor productivity; the annual budget has decreased by staff recruitment on 450–600 thousand rubles; costs of training of personnel of 20% were reduced.

Abstract
In article, the questions connected with approach on effective development of industrial enterprises on the example of the furniture entities are considered. Effective development of the entities is directed to cost reduction in case of production and implementation of products, for improvement of indicators of financial and economic activities. The research is conducted on the example of the furniture entities of the Voronezh region and Krasnodar Krai. Any entity constantly uses these or those resources connected with material, labor and finance costs. All resources, which are consumed during a certain production cycle, create a cost budget or the expense plan of the entity, which are the most important economic indicators of activities of any entity. Not always at the entities the attention is properly paid to forecasting of production expenses for a further stage of functioning. Most the entities will organize the activities in such a way that current plans pass from year to year, and at the same time the alternative ways directed to cost reduction in case of production and further sales of products aren't considered. Any entity needs forecasting and planning of costs for the following production stages, for the purposes of innovative development and effective functioning of productive activity of the entity. First, it is necessary for assessment of opportunities when financing productive activity and for further scheduling of expenses, directed to cost reduction and cost reallocation. Having analysed activities of the entities and having studied accounting (financial) records, it is revealed that at the entities in 2015 in comparison with 2014, there was a decrease in outputs, but at the same time, the loss is observed. Based on the carried-out analysis, on the example of financial and economic activities of JSC GRAFSKOYE and JSC GKMF, conclusions are drawn, cost reduction allowances in case of production are revealed, and recommendations in case of cost forecasting are selected for production.

Currently becoming more widespread non-standard forms of employment. If this is not clear approach to the definition and maintenance of non-standard employment. In the article the analysis of diverse interpretations of the concept, on what basis, the author makes a conclusion about the complexity and contradictory nature of precarious employment as an economic category. It examines different approaches to classification of forms of precarious employment. The main forms of precarious employment such as flexible working year, flexible working week, flexible working hours, remote work, employees on call, shift forwarding; Agency employment, self-employment, negotiator, underemployment, over employment, employment on the basis of fixed-term contracts employment based on contract of civil-legal nature, one-time employment, casual employment, temporary employment, secondary employment and part-time. The author’s approach to classification of non-standard forms of employment, based on identifying the impact of atypical employment on the development of human potential. For the purpose of classification of non-standard employment forms from the standpoint of their impact on human development as the criteria of classification proposed in the following: working conditions, wages and social guarantees, possibility of workers ' participation in management, personal development and self-employment stability. Depending on what value each of these criteria, some form of non-standard employment can be attributed to the progressive or regressive. Classification of non-standard forms of employment should be the basis of the state policy of employment management.

Abstract
The growth of the Russian economy coupled with its competitiveness is impossible without the development of innovative capacity of regions and enterprises. The development of the regions is based on the consideration of the competitive potential, which, in turn, relies on an innovative vector of development. The government makes insufficient use of their opportunities in terms of tax activities and excessive centralization. Explain how uses the state and the region these opportunities. The lack of strategic plans for the development of innovation, stringent approach to taxation. Not taking into account the development of competitive technologies and products. Does not allow developing enterprises in the region as innovative structures. Note that the basis of competitiveness is innovativeness of the economy as the most important criterion of expediency of entering of enterprises into national and global markets. Thus, under the innovative economy understand new products. Change management and organizational structures. Technical and technological innovations brought to the target markets. To date regional government has very limited ability to invest in innovation. In conditions of limited budgetary and financial investment in the country’s internal potential of territories is the main resource of their development. Rational use increasing the resource potential of the regions is one of the important priorities of the regions (local authorities and territorial communities). In the processes of functioning and development of enterprises and regions requires a constant search for ways to improve their innovative capacity. Transferring its production resources in viable and dynamic clusters. Development of innovative system will allow competing to companies. Regions and the state as a whole in difficult market conditions.

Abstract
The article considers corporate culture as a management tool in the economic model of the activity underlying the organization of management of all factors of production (labor, materials, capital and information). Companies with well developed corporate culture are developing successfully. Weak corporate culture can become a source of deep crisis of the entrepreneurial structure. It is emphasized that the set of factors influencing the development of entrepreneurial structures must be supplemented with a factor of effective corporate culture. Reforms aimed at changes in property relations require the creation of an adequate organizational and economic mechanism for the management of corporate enterprises, taking into account current trends in the concentration and specialization of agro-industrial production. A corporate culture is presented that includes the strategic objective of the firm; Standards of personnel behavior; Structural characteristics of personnel, nature, content, working conditions and methods of its organization; Incentive system; System of personnel training. The types of corporate culture and their features are singled out, namely the culture of power, the culture of roles, the culture of tasks and the culture of individuals. The unique essence of the corporate culture, the complexity of its assessment, create certain problems in the management of corporate culture. Corporate culture provides an opportunity to competently and effectively manage the organization. A strong and solid corporate culture is a necessary attribute of a successful company, as it unites employees who identify with their organization and strive to achieve a common goal by joint efforts. In such a company, key corporate values are shared by all members of the organization, the dominant culture strongly influences the behavior of employees, the need for high structuring and formalization of the company’s activity disappears, and the turnover of staff is reduced.

Abstract
In this article, problem zones of the current stage of the development of the Russian Federation's economy are considered, the solution of which presupposes a profound modernization of the socio-economic system and its innovative transformation. The fulfillment of these tasks is facilitated by the formation of scientific bases for the management of this process as a whole and the conditions for its implementation in particular. A key condition for effective innovative activity is the creation of an effective external and internal environment for the functioning of business entities that take part in the creation and production use of modern scientific and technological achievements. At the same time, a comparative analysis of literary sources is conducted and the main factors of the internal and external environments of the functioning of organizations that influence the formation of innovative environments in organizations are identified. The use of this technique allows the author to formulate an opinion on the degree of impact of these factors and on the innovative activity of organizations and the possibilities of both the management response of organizations to them and the preventive impact. In the domestic and foreign scientific literature, research in the management of the formation and functioning of the innovative environment of the organization is not sufficiently represented, including the lack of unity of the conceptual apparatus, which significantly complicates the concerted activities in this field. The author based on the analysis of opinions of scientists offers his understanding of the term "innovation environment" and related concepts, adapted to the goals and objectives of management of innovation processes. The article proposes an authorial system of classifications of innovation environments, which can be used to make informed management decisions. The article ends with the formulation of requirements for the notion of an innovation environment that allows to expand the possibilities of innovative development in managing the activities of economic entities, and the author's vision of the definition of an innovation environment allows leaders of domestic organizations to build guidelines for the further development of their organizations, in addition, the definition creates a reserve for conducting comprehensive scientific Research in the declared field.

Abstract
Railway transport is one of the system-forming sectors of the economy, requiring huge financial investments. At the same time, the sphere of transport can become an instrument for overcoming the economic crisis and creating conditions for the growth of the national economy, as investing in the transport industry contributes to the development of related industries and the provision of jobs. The development of transport infrastructure to meet the needs of the economy and the implementation of transit potential is a strategic direction outlined in the Strategic Plan of the Ministry of Investment and Development of the Republic of Kazakhstan for 2014–2018. The task of Kazakhstan is to ensure an increase in the transit freight traffic between the People's Republic of China and the European Union, which goes on a land route through the territory of the republic. So, according to the results of 2014, the volume of transit traffic amounted to 17.5 million tons, revenues from transit transportation amounted to 180 billion tenge. JSC "Astyk Trans" is currently one of the largest operators in the market of railway transportation of grain cargo in Kazakhstan, but slightly inferior to JSC "NC "KTZ" in domestic transportation of 42042 wagons to 45049, while for export shipments to the share of JSC "AstykTrans" there are 34787 carloads, which is 50.3% of transportation of JSC "NC "KTZ ". In order to increase the efficiency of transport and logistics services, reduce the distance and time of delivery between the busiest sections of the railway, construction projects for transport and logistics centers and the formation of an internal terminal network are planned in the industry. By 2020, the railway industry plans to build 1400 km of new railway lines to accelerate the delivery of goods and passengers within the country and beyond Kazakhstan, with at least 50% of the financing of construction to be carried out through private investment. The state for its part can provide tax and other benefits, guarantees, subsidies, subventions, direct reimbursement of investment costs.

Abstract
The formation of an innovative economy must correspond to the promising areas of development of scientific, technical and social progress. To ensure sustainable innovative development of the national economy, it is not only necessary to develop our own tools and mechanisms that are characteristic of the domestic management model, but also the rational use of foreign experience in this field. Analysis of international experience in the use of various tools and mechanisms, management structures for the creation of high-tech and knowledge-based enterprises showed: the integrated nature of innovative development and modernization of the economy is the most sound methodological approach of a phased, systemic transition to new technological structures; When developing tools and mechanisms for innovative development of the economy, one should take into account the actual state of the material and technical base and the existing industrial structure of production, take into account the real possibilities of using different types of resources. The greatest innovation activity is shown by those countries in which the national integrated system effectively provides favorable conditions for the development and introduction of innovations in various spheres of life. International experience in the use of forms of governance can be considered as a mobile system of relations with the real sector of the economy. In the article is given the experience of foreign countries, and examples of adaptation for Kazakhstan integrated models of management of innovative processes to create high-tech enterprises, innovative products which can be competitive in the world market. The author highlighted the role of JSC “Kazakhtelecom” with the widespread provision of public services, having the status of a National operator associated with the provision of the services including long-distance and an international telecommunication for telecommunication networks in General use.

Abstract
The article presents the criteria and indicators that characterize the country's food security. The foreign experience in the regulation of food security is considered, the use of which in the Republic of Kazakhstan will create conditions for the sustainable development of production, increasing the competitiveness of domestic products, and the formation of an efficiently functioning food market. At the initial stage, the evaluation criteria were the per capita incomes of the population and the carryover stocks of food grains (first at the level of 20% and then 16% of the total annual consumption), now the evaluation criteria are expanding and becoming more complex. The criteria for food security include: the sustainability of the development of the agro-industrial complex (APC), fisheries and forestry, which increases the production of food to increase inventories and in the event of food aid to other countries that have suffered natural disasters or wars; A high level of scientific achievements, increasing technical and technological equipment, improving the gene pool of livestock and crop production; Environmental and nature conservation policies and practices that ensure the conservation and improvement of soil fertility, yield, etc. When establishing the criteria for national food security, it is necessary to take into account that they should characterize the level of satisfaction of the population’s food needs, as well as the degree of sustainability of the country’s food supply. The economic basis of national security in the food sector is the provision of basic food for the population of the country. This means that if an uninterrupted supply of basic foodstuffs is sufficient for medical purposes, the country’s food security can be considered guaranteed.

Abstract
The article is devoted to topical problems of small business development in the world production practice. The main tendencies of development of small business in modern conditions are noted, in particular, the directions of development of innovation-oriented small business are considered on the example of the Republic of Kazakhstan. Domestic and foreign experience has proved that supporting small businesses from the state is an integral part of the market economy. Small business, gaining a solid position in the market, needs development and state regulation. In foreign countries, small and medium-sized businesses represent an important sphere of employment for the population, promotes the development of the innovative potential of the economy, and the search for and introduction of innovations that are a factor in obtaining competitive advantages for enterprises, industries, regions. To realize its potential, state support should be carried out simultaneously in several directions, which will enable it to cover all small business sectors: the sphere of real production through the subcontracting mechanism, the sphere of circulation through the franchising mechanism, the sphere of applied science through the mechanism of venture contracts. It is also necessary to have banks specially created to participate in small business support programs and the activities of "business incubators". For a significant rise in the national economy, it is necessary to promote the maximum increase in the number of small innovative enterprises in the production sector, to stimulate the development of interrelations between small, medium and large industrial business, to creatively use the relevant foreign experience. All this should become an integral part of the overall policy in the field of restructuring the domestic economy, since business as a whole, regardless of its scale, is a single and interrelated process.

Abstract
The problem of pedagogical professionalism is complex and multifaceted, as evidenced by the interest of philosophers, sociologists, psychologists, teachers, acmeologists and scholars of the humanities and applied sciences to study the various aspects of its formation. The modern education system should not only develop the intellect of trainees, improve its capabilities - it should practically orient it, manage the attention and actions of students, teach them the process of independent learning and development, expand their innovative and creative potential. Analysis of the theory and practice of training specialists points to the existence of a generally accepted belief that the future of society, its progress and successful development depends on the quality of education, the level of education of people, the availability of qualified professionals and their professionalism. Analysis of psycho-pedagogical and other literature shows that intensive technologies are often considered as a special sphere of social life, creating external and internal conditions for the development of the individual in their interaction in the process of developing the values of culture. New intensive technologies for teacher training, directions of pedagogical work are also dictated by the processes of integration and differentiation of various types of activities. Increasing importance is the mastery of specialists in the process of preparation of those general, invariant, which is typical for various activities. At the same time, the requirements for a specialist are increasingly differentiated depending on the characteristics of its specific type of work. Based on the analysis of the work done, it can be concluded that all educational objectives are best realized directly in various intensive technologies.

Abstract
In modern conditions of digitalization of the economy, its integration with the policy society questions of formation and development of corporate culture of the learning organisation are of particular relevance. Digital transformation of business dictates the need for the emergence and development of learning organizations, creating and preserving knowledge. In this situation, the openness of issues of assessment of efficiency of processes of formation and development defines the importance of the proposed research. Corporate culture is regarded by most scholars as the most important internal resource of the organization, able to provide her with stability in a crisis and give impetus to the development and transition to qualitatively different levels of the life cycle. This position assumes that a strong corporate culture should be aimed at building a learning organization, able to quickly adapt to changes in the external and internal environment. This article examines the issue of assessment of efficiency of corporate culture; it is shown that in addition to the empirical, sociological methods and qualitative approach to evaluation, is acceptable investment approach. This option appears when you use the aggregate target-oriented and project management methods, which allows in a systematic manner to carry out the formation and development of corporate culture. The assessment should be subject to software development activities and (or) development of the corporate culture of a learning organization. In evidence to draw conclusions on the example of agricultural companies, a calculation of the economic efficiency of the program of formation of corporate culture of a learning organization. Calculation of net discounted income, the net present value of the project, profitability index, project profitability, payback period. This confirms the social and economic effects of the proposed program on the formation of corporate culture of independent learning.

Abstract
Inventory management for a trading company is a vital task, which requires processing significant amounts of information. Through the application of ABC/XYZ-analysis of the nomenclature within the enterprise ERP-system, it is possible to increase significantly the efficiency of inventory management, in accordance with Pareto principle concentrating on managing the most important categories of goods. Various researchers dealt with the methods of ABC/XYZ-analysis itself but its usage as a part of the inventory management and procurement subsystem has a number of essential features, ignoring of which can lead to tangible negative consequences. The article discusses the methods and key problems of application of ABC/XYZ-analysis within the enterprise management accounting information system. For each of the factors that can affect the reliability of sales and procurement statistics and distort the results of the classification of goods, we have formulated the proposals to minimize the negative impact of that specific factor. Proposed methods allow reducing the impact of the following factors: availability of conditions for duplicate nomenclature to appear within the enterprise accounting software, the lack of a unified approach to the formation of names for newly created items of nomenclature, frequent changes in the products range of the suppliers, excessive detailing of information about a product in its name. The results of successfully implemented analysis and classification of goods can be used for a wide range of tasks varying from implementing effective inventory control to general planning and forecasting commodity flows as a part of the enterprise budgeting model. Solving these problems will harmoniously fit the inventory management in the managerial accounting system making it an effective tool in achieving strategic business goals.
