The formation of extracellular polysaccharides is a fairly well-studied property of bacteria that is used for the industrial production of such extracellular bacterial as xanthan, dextran, gellan, hyaluronan, etc.. Polysaccharides synthesized by fungi are also widely used, such as schizophillan and scleroglucan. However, polysaccharides synthesized by yeast and yeast-like fungi have not yet found wide industrial application, with the exception of pullulan produced by Aureobasidium pullulans yeast, although there are a number of promising developments in the use of yeast polysaccharides in medicine. Yeast synthesizes polymers that contain mannans, glucans, phosphomannans, galactomannans, and glucuronoxylmannans. Polysaccharides produced by different species, and sometimes even by different strains of the same species, may differ in chemical composition and structure. Such a variety of composition and properties opens up great prospects for their use in various fields: medicine, chemical, food and cosmetic industries, as well as feed additives. In this regard, the search for new producers of polysaccharides is very relevant. Yeast of the genus Lipomyces is found in the soils of the southern and northern hemispheres of the Earth, except in the high-mountainous regions and tundra soils, where soil formation processes are in early stages of development, but the soils are rich in steppe and forest zones. As a result of the research, it turns out that from the point of view of biomass growth on the presented nutrient medium at the temperatures studied, the strains of the Lipomyces lipofer yeast КБП Y-6267 and КБП Y-6265 attract the most attention, especially at low temperatures. With an increase in temperature, the increase in biomass in these yeasts decreases markedly. As producers of extracellular polysaccharide, it is worth noting the КБП Y-6267 and КБП Y-6264 strains at 20 °C and the КБП Y-6268 strains and the КБП Y-6234 at 30 °C, which indicates the possibility of using for these purposes different species of the genus Lipomyces. At 30 °C, Lipomyces lipofer strains of the КБП Y-6268 and Lipomyces kononenkoae КБП Y-6234 had the highest enzyme activities, however, there was no relationship between enzyme activities, biomass gains and polysaccharide yields at low temperatures.

The amylosecontents in starch is one of its qualitycharacteristics. Generally it is a specific sign of astarch-containing material and the starch received from it. Physical and chemical properties of starch and its use in the national economy depend on it. In small quantities the amylose is received by starch fractionating. It is the difficult and expensive technology. Selectors carry out research workson creation of new varieties of potatoes, grain and leguminous crops with the increased content of amylose in starch. They need techniques of definition of amylose in different types of raw materials. But before developing a technique, it is necessary to investigate optical properties of this or that type of starch and the components making it. It showed from researches, different types of starchhad differentoptical properties of itscomponents. For example, the technique developed for definition of amylose in corn starch isn't acceptable for its definition in starch of triticale and wheat. Earlier we studied properties of iodine polysaccharides of corn and triticale starches and factors affecting the optical properties of iodine polysaccharides. In this work it was investigated the influence of amylose, concentration of iodine and potassium iodide at KI:I from 3 to 15 on an optical density of wheat iodine polysaccharidessolutions. It is established that the iodine amylose of wheat has a maximum at 600 nanometers, an iodine amylopectin has at 565 nanometers. Spectra of wheatpolysaccharides differ in value of an optical density ?max and a form of curves from related polysaccharides of triticale. Concentration of an iodine in the studied solution has to be equal 0.6 mg/cm3, and a ratio of potassium iodide to an iodine has to be 5.

The use of intensive technologies in industrial livestock leads to an increase in the stress sensitivity of animals, a decrease in their immune status and the development of pathological conditions. To increase the safety of young stock, including by reducing its incidence and death from diseases, feed additives are being developed, including probiotics, prebiotics and (or) other components that stimulate the immunological resistance of animals, their growth and productivity. This article examines the effectiveness of the use of a complex feed additive containing a multienzyme enzyme preparation, the probiotic preparation Prolam and amaranth oilcake to increase the efficiency of growing calves. The studies were performed on calves of the red-motley breed from 10 days of age in Voronezhpishcheprodukt LLC. The study of the effect of the feed additive on the immune and clinical status was carried out on 40 calves, which were divided into 4 groups. The calves of the three experimental groups used the feed additive at a dosage of 5, 10 and 15 g per day from day 10, the control drug was not used. The use of a complex feed additive to calves in the neonatal period helps to optimize the process of formation of intestinal microbiocenosis, increase the body's natural resistance and adaptive immune response to antigenic effects, accompanied by a decrease in the incidence of animals, the duration and severity of gastrointestinal pathology. The use of the feed additive in the dosage of 10–15 g / head per day favorably affected the growth rate and the natural resistance of the body of calves. The data obtained are the basis for the inclusion of feed additives in the diet of young farm animals.

A technique is proposed for the experimental determination of internal friction in food materials, as well as a device based on a torsion pendulum with laser registration of the angle of rotation, which ensures the minimum relative displacement of the layers of the material under study in the measurement process. The definition of internal friction is based on finding the attenuation of a torsion pendulum connected to a cylinder immersed in the medium under study. As an example of the application of the method to food systems, the dependence of internal friction on viscosity in solutions of sucrose and glycerin is determined. This dependence is linear for sucrose solutions and non-linear for glycerol solutions, which may be due to the interaction of hydrated molecules in solutions. Examples of the application of internal friction measurements in the study of membrane concentration processes are given. The method of internal friction was used as an auxiliary rheological method in a comprehensive study of the process of deposition of concentrated substances on membranes during ultra- and nanofiltration of whey. Thus, it has been shown that, despite the thinness in comparison with the membrane, the polarization layer makes a significant contribution to the internal friction of the membrane-layer system. This leads to a sharp decrease in the flow of curd whey filtrate through the membrane, compared with the flow of water under the same conditions. The dependence of internal friction on the concentration in the curd whey that underwent electroflotation treatment was determined, as well as the thermal isomerization of the lactose contained in it. Using such curves, the relationships between the permeability coefficient Lp * in the Kedem–Kachelsky equation and the parameters of the nanofiltration process of given food systems can be found.

Now the increasing popularity is received by food semi-finished products from the bulk materials. With increase in volume of their production it is expedient to mix powdery materials in the mixers of continuous action. For the set working hours of the mixers of continuous action the movement of material in the device is considered to be casual stationary processes between which there is relationship of cause and effect. Key indicators for her assessment is the correlation coefficient, population mean and dispersion. Communication between entering and going out of the device signals is established by means of the equations of material balance, describing expenses of streams of bulk stochastic stationary functions X (t). Further, finding probabilistic characteristics of the entering and leaving signals, it is possible to judge "quality" of operation of the mixer or to select the required topology of streams in the hardware environment by comparison of the relations of their dispersions or mean square deviations. In this work the scheme of the movement of material streams in the mixer developed by us realizing a method of "consecutive dilution" is considered. By means of the system of the equations of the material balance displaying process of the movement of material in the mixers of continuous action of vibration type influence of recirculation on the smoothing properties of the device is considered. Values of size of the smoothing ability of S from recirculation coefficient ? and quantities of rounds of n are given. It is revealed that increase in the smoothing ability leads to increase of quantity of rounds, and respectively and dimensions of the mixers of continuous action of vibration type, therefore, it is expedient to use the mixer with quantity of rounds equal 6 and coefficient of recirculation equal 0.7 as at the same time the smoothing ability equal is enough 1753 for receiving qualitative ready mix at a ratio of components 1:50. By means of the correlation analysis it is possible to predict uniformity of a material stream at the device exit at the known values of the time spent in him of material, coefficients of recirculation and dispersion of an entrance signal.

A composite Co-Al2O3/SiO2/HZSM-5 catalyst has been developed for one-step synthesis of fuel series hydrocarbons from CO and H2. The catalyst was obtained by mixing and forming powders with a Co-Al2O3/SiO2 catalyst, zeolite HZSM-5, and boehmite Al(O)OH?H2O. The physicochemical methods XRD, PEM, BET established the phase composition of the catalyst, the particle size of cobalt (8.2 ± 1 nm), its specific surface area (286 m2/g). Tests were carried out in the synthesis of hydrocarbons from CO and H2 for 60 hours at a temperature of 240 ° C, a pressure of 2.0 MPa, and a gas flow rate of 1000 h-1. It is shown that synthesis gas diluted by 40% with nitrogen can produce liquid C5+ hydrocarbons with a selectivity of 69% and a productivity of 81 kg/(m3?h). The yield of С5+ hydrocarbons was 70 g/m3 of the leaked synthesis gas and 135 g/m3 of the converted synthesis gas. Synthetic oil has a molecular mass distribution close to monomodal (the probability of chain growth is 0.81), 88% consists of gasoline and diesel fractions and 12% of long-chain C19+ hydrocarbons. The ratio of isomeric hydrocarbons to normal hydrocarbons (iso/n) is 1,26, and the ratio of olefinic hydrocarbons to paraffinic hydrocarbons is 0,97. In the gasoline fraction of hydrocarbons (C5-C10), a high content of alkenes of normal and branched structure (76,3%) is noted, the proportion of iso-alkanes and n-alkanes is 10,8 and 12,9%, respectively. The catalyst showed stable operation, the rate of its deactivation is comparable to the rate of deactivation of a commercial bifunctional catalyst.

This article presents an overview of promising catalysts, the selection of the most effective, calculated the economic effect of the introduction of a new catalyst. The selection of catalysts providing stability of operation and high rate of oxidation of hydrogen and methane flowing in the reactor P 2 of the helium fine purification unit of helium production from helium concentrate was made. To ensure the technological process in the production of chemical, gas processing and oil refining enterprises, catalysts of different modifications and types of both domestic and imported production are used. For stable operation and high oxidation rate of hydrogen and methane flowing in the reactor P-2 of the helium fine purification unit-22 of the Orenburg helium plant, the AP-56 aluminum-platinum catalyst is used. The catalyst AP-56 participating in oxidation processes in connection with the improvement of the technological process does not meet the standards established in the technological regulations, including an increase in hydrogen concentrations, and this in turn worsens the quality of gasoline fractions, in addition, the catalyst AP-56 is promoted by chlorine, which contributes to the development of corrosion on heat exchange equipment located after the reactor. The above circumstances forced manufacturers to reduce the production of aluminum-platinum catalyst AP-56. The most productive among the units of fine cleaning plant, which includes 3 similar compartments with a capacity of up to 400 Nm3/h for raw materials, is considered. To confirm of the selected catalysts on existing equipment and for implementation, the technological calculations of the catalytic purification unit were made, and the main indicators of the process were determined.

Studies on the analysis of composition of wastewater from chlorine and alkali production process, sampled at the treatment different stages, treated by electrolysis and the mercury cathode use, are presented in this paper. It is demonstrated that Hg-content range in the wastewater entering the post-treatment stage is 14.06–14.15 mg/dm3. Hg-ions sedimentation and filtration allow to reduce such content to 0.005 mg/dm3, while the final post-treatment stage with use of the anionite of АВ-17-8 type allows to achieve Hg-concentration in effluents discharged to water bodies with range of 0.001–0.002 mg/dm3. In addition to mercury, the wastewater contains relatively high concentrations of sodium, potassium, iron, aluminum and calcium ions. The main anion type in waste water is a chlorine anion; its content can be significantly reduced only after the post-treatment with the anionites. Experimental studies were carried out on the use of carbon sorbents in the process of wastewater post-treatment with regard to Hg-ions after the sedimentation and filtration stage. Tests of modified carbon sorbents for Hg-ion removal from standardized test solutions with different concentrations were carried out under static conditions. It was demonstrated that the higher post-treatment degrees were achieved with active carbons of АГ-3 and АГ-5 types, modified with HNO3 and MnS. Purification degree was 97–99% with 1,0-11,8 mg/dm3 Hg-concentration in treated solutions. Usage effectiveness of active carbons of АГ-3 and АГ-5 types (produced at “Sorbent JSC” Perm, Russia), modified with active compounds, was demonstrated.

In the electroplating industry, large volumes of water are used, which are polluted at various stages in the process. Waste water containing transition metal ions is not only a dangerous source of environmental pollution, but also valuable waste. Taking into account the problems associated with the ecology and the rational use of natural resources, it is necessary to create low- and non-waste production, in particular, to develop new technological processes and appropriate equipment, to introduce water-circulation cycles. This paper presents the results of a study of the sorption of copper (II) and nickel (II) cations by the FIBAN X-1 ion exchange fiber. Calorimetric studies of the thermal effects of the interaction of FIBAN X-1 fiber with solutions of copper (II) and nickel (II) nitrates were carried out. It is shown that the power, thermal effect and time of the process depend on the nature and concentration of metal ions in the solution. Based on the experimental data, the enthalpy of the process was calculated. The endothermic effect of the process is explained by the energy costs associated with dehydration effects and changes in the conformation of the polymer fiber chains. Sorption isotherms of these ions were obtained. It has been established that at all concentrations studied, Ni2 + ions under these conditions are absorbed by ion exchange fibers better than Cu2 + cations. The calculated sorption constants for copper (II) and nickel (II) are greater than 1. It is shown that the Langmuir equation describes the sorption isotherm better than the Freundlich equation. For deep purification of waste water from metal ions, it was proposed to use the fibrous sorbent FIBAN X-1.

The conducted information review showed that there are various types of radio absorbing materials. The expansion of the working wavelength range for radio-absorbing composites is possible due to the combined use of conductive fillers, characterized by different magnetic and dielectric characteristics and the value of electrical conductivity. As a rule, the increase in the efficiency of radio absorption of materials is associated with an increase in the concentration of metal fillers in them, as a result of which the weight and size parameters increase proportionally. To avoid this, the use of carbon nanomaterials, which have the ability to create self-organizing hierarchical structures in the bulk of the composite, allows. Varying the composition of the catalytic systems of the CVD process allows directional synthesis of carbon nanomaterials with the necessary morphological characteristics. To assess the effect of the composition of the catalyst on the morphology and structure of the synthesized CNTs, 3 Ni / MgO catalyst compositions with different contents of the active component (Ni) were selected. The effectiveness of the obtained catalysts was determined by the specific yield of CNTs (gC/gkat). The morphology and structure of the catalysts and the synthesized CNTs were studied by means of scanning electron microscopy (a Hitachi H-800 transmission electron microscope). CNTs were additionally examined by transmission electron microscopy (a Hitachi H-800 transmission electron microscope). The use of a nickel-based catalyst provides the material with magnetic properties. The diameter of carbon filiform formations synthesized on Ni/0.16MgO and Ni / 0.3MgO catalysts is ~ 30 ? 60 nm. The Ni/0.5MgO system is characterized by low productivity in one-dimensional nanostructures; the sample after the CVD process contains a large number of unstructured forms of carbon and an unchanged catalyst. Structural diversity in carbon nanomaterials allows to obtain on their basis an effective hierarchical structure in the radio absorbing composite..

Red Muds (R.M.) – waste of bauxite reprocessing by the Bayer's method include many rare elements, such as Gallium, Titanium, Zirconium, Rare Earth Elements and Scandium, concentration of which in its reached 130 g/t. In the problem solving of Scandium extraction from R.M. get a two directions: immediate leaching of Scandium from R.M. and in passing Scandium recovery under complexing processing of R.M. The method of carbonate leaching of Scandium from R.M., which was work out in Institute of Solid State Chemistry Russian Academy of Sciences Urals Branch, include saturation by carbon dioxide of alkaline solutions, obtained after water process of R.M. and allow up to 20 % Scandium recovery in solutions. It is not effective for work out of technological scheme of R.M. processing. In recent paper, the chemical aspects of carbonate leaching of Scandium from R.M. in heterogeneous systems solid – liquid – gas carbon dioxide were investigated to determine of conditions for more Scandium recovery from R.M. It was shown, that Scandium leaching by aqueous sodium solutions without carbon dioxide gives small recovery yield and accompanied by alkaline hydrolysis under high pH in concentrated Na2CO3 solutions. Under saturation by carbon dioxide of carbonate R.M. pulp, the hydrolytic polymerization of hydroxocarbonates of Scandium and Aluminum in presence of carbonic acid proton take place. In the both process secondary precipitates are settle down and reduce of Scandium recovery yield. For increase of Scandium recovery from R.M. it is necessary to exclude the secondary precipitates under carbonate leaching with saturation by carbon dioxide.

One of the most common methods of preserving apple pomace in order to further obtain products with a high content of biologically active substances is drying. For the experiment, a method of drying with superheated steam of reduced pressure in a pulsed vibro boiling layer was chosen, since it allows improving the quality of the finished product by lowering the temperature of the drying agent, thereby retaining a significant amount of nutrients in the original product. To study the kinetic and hydrodynamic dependences of the drying process, an experimental setup has been developed and created, which allows to obtain the most accurate and reproducible results. According to the results of the experiments done, the drying curves, the drying rate curves and the heating curves were constructed. The technological modes of operation of the drying unit are determined, ensuring a minimum of the specific energy consumption of the drying process and the maximum moisture stress of the drying chamber. In addition to the experiment on drying apple pomace, a study was also conducted on the content of pectic substances in dried pomace. To determine the amount of pectin and protopectin, the calcium-pectate method was used. During the experiment, it was found that with the proposed method of drying, the yield of pectin substances is increased compared with traditional methods. Histograms of the content of pectin and protopectin were constructed depending on the method of drying. A comparative analysis of the content of pectin and protopectin was carried out depending on the drying mode for apple pomace and sugar beet pulp. The conclusion is made about the increased thermolability of protopectin in apple pomace compared to sugar beet pulp.

The tests found that the composite of structure of PE : MCc of has a density of 410 kg/m3 and a porosity of 60%, the roughness of 3.5; the composite of structure of PE : MCw has a density of 590 kg/m3 and a porosity of 40%, roughness of 2.0, composite of structure of PE : ST has a density of 640 kg/m3 and a porosity of 50%, the roughness of 2.5; wherein the reference sample - PE - has the parameters: density 860 kg/m3 and a porosity of 0%, roughness 0. To determine the immobilization capacity of the new composite materials, a laboratory experimental immobilizer was used, which is a container filled with 70% of the useful volume of the active sludge suspension and 30% of the floating loading samples. Immobilization was carried out under aeration conditions during 2, 4, 8, 12, 24, 48, 72 hours. As a result of tests it is established that the sample of structure of PE : MCc for 72 hours of immobilization showed a gain of biomass of the order of 12%, the sample of structure of PE : MCw - 5%, the sample of structure of PE : ST – 7%, PE – 3%. The condition of the organisms AS after fixing was evaluated by washings with immobilized samples, as a result of microscopy of washouts, the presence of living representatives of the biocenosis of AS in all samples was established, but they differ in number: for the sample of structure of PE : MCc - numerous, PE : MCw, PE : ST - average number, PE - small number. Further studies on the modification of the synthetic polyolefin matrix by functional fillers, including those from a number of polysaccharides, are of interest, allowing to increase the affinity of the carrier material with the extracellular matrix of activated sludge.

Authors: Vinogradova L. A. , Gracheva Yu. N.
Published: March 2019

In order to improve the properties of concrete, various chemical additives are introduced into the concrete mix which can significantly reduce the level of costs per unit of production, improve the quality and effectiveness of concrete and reinforced concrete structures, increase their service life as well as buildings and structures as a whole. This paper presents the results of the regulation of the setting speed, strength and frost resistance of concrete modified with the universal additive BEST LLC “Makra”. Portland cement CEM I 42.5 B of Mordovcement OJSC was used as a binder; the aggregates were enriched quartz sand from the Khromtsovskoye deposit with a size of 2.4 and granite rubble of the Orsk deposit of 5–20 mm with water absorption of 0.2% .The effect of the universal BEST additive on the construction and technical properties of concrete was studied by determining the binder system setting speed and the hardened composition strength characteristics. Data analysis showed that the introduction of a regulator in the amount of 0.3% into the concrete mixture contributes to the long-term preservation of its mobility (up to 4 hours) due to the water-proof modifier adsorption layer formation on the cement grains surface. With an increase in the content (0.5–1.0%) of BEST in the system the concrete setting speed acceleration was established due to the additive deflorulating effect. We have identified an increase in the strength characteristics of the modified (by 41%) concrete compared with no additional. Besides, the introduction of the universal additive BEST allows you to adjust the concrete frost resistance ~2 times possibly due to accelerated formation of calcium hydroxides gels.

Among the existing characteristics of a financial condition of the enterprise a specific place is held by a three-component financial situation indicator (degree of a covering of stocks by own sources) which considers some arti-cles of balance which are seldom used at usual assessment of a financial state. Therefore for establishment of im-portance of this indicator it is offered to pass from a discrete three-component indicator to a continuous indicator – coefficient of sufficiency of a stocks covering with own sources of means and to carry out the correlation analysis of communication of the last with results of the scoring analysis of the same enterprises. To consider influence of a three-component indicator on the general results of assessment of a financial state, the technique of accounting of its influence on the example of indicators of structure of the capital is developed, i.e. the set of the considered finan-cial coefficients due to introduction of additional sign – the mentioned coefficient of sufficiency of a stocks cover-ing is expanded own sources. Comparison of estimates of the generalized indicator of structure of the capital before expansion at the expense of sufficiency coefficient in an indistinct set form allows define the recommended scopes of the offered approach.

The world experience of implementation of import substitution strategy is being studied; reveals the essence of the main models; Identify those aspects that will prove useful in modern Russian conditions. The development of import-substituting industries according to the intra-oriented strategy is carried out in order to develop exclusively the domestic market of the country. From the point of view of the national economy, this strategy leads to the preservation of the backlog, primarily in the field of technological and scientific-technical cooperation and prevents the emergence of industries in the economy-locomotives that can ensure the world level of progress. The use of this model of import substitution has become a determining trend in the development of the so-called new industrial countries (NIS).The intra-oriented strategy of import substitution plays a stimulating role in creating a diversified national economy, expanding the production of important goods on its own. The conceptual basis for the implementation of this strategy was the theory of the peripheral economy, developed by a group of Latin American scientists headed by the Executive Secretary of the UN Economic Commission. According to this concept, the demand for products. The use of the designated model of import substitution has become a trend of development of the so-called new industrial countries of Latin America. Another option for the implementation of import substitution policy can be a strategy of foreign-oriented import substitution, which is characterized by the achievement of structural changes in the economy through the replacement of imported components and parts in export products. Implementation of import-substituting policy, according to this model, involves the development of production of national goods on a sufficiently large domestic market, followed by their promotion on the world market.

The article analyzes the causes of priority development territories (TOR), discussed the benefits provided by the state to residents of the top, highlighted the steps of forming the top. The territory of the advanced social and economic development is understood to be part of the territory of the subject of the Russian Federation, including a closed administrative and territorial formation, in which, in accordance with the decision of the Government of the Russian Federation, a special legal regime for the implementation of entrepreneurial and other activities is established to create favorable conditions for attracting investments, socio-economic development and the creation of comfortable conditions for the provision of livelihoods nosti population. The objectives of the creation of priority development areas are: the development of high-tech sectors of the economy, improving the competitiveness of the economy, creating new jobs and improving the quality of human resources, the alignment of the territorial imbalances, the production of new import-substituting and export-oriented products, and more. The need to attract investment to the territory, not only the problem of the Russian Federation regions and the country as a whole, has become another impetus for the creation of areas of advancing socio-economic development. For residents of the TOP, the following rights are provided: the right to release VAT from the duties of a taxpayer for 10 years from the date of obtaining the status of a TOP resident; establishment of a zero VAT rate in respect of goods (works, services) imported to the TOP for use by TOP residents; use of accelerated depreciation on the objects of depreciable property belonging to them; a lowered rate of corporate income tax. Thanks to the above measures, the cost reduction of business will be from 40%, which will be a huge incentive for business opening in the territories of Eastern Siberia and the Far East.

In modern development conditions of Russian energy sector, the innovative approach method is recommended to use. Due to the presence number of global and local problems, the need to modernize the social reality in energy management arise. In these conditions, the major tool is the innovative social designing. The innovative development of energy, described in the framework of long cycles, appears today in a dual context: technological (improving the efficiency of existing technological processes, the emergence of fundamentally new technologies and energy resources) and social (development of synergetic and Smart directions, organizational management and systems of integrated innovation management). Innovative processes, their implementation in new products and technologies are the foundations of economic development. In the works of foreign authors developed the theoretical foundations of the organization of social innovation projects, much attention is paid to the introduction of scientific and technical achievements, taking into account the features of modern production. Innovation as an economic category is now more relevant than ever and reflects the most common features, attributes, links and relations of production and implementation of innovations. Innovation as an economic category is now more relevant than ever and reflects the most common features, attributes, links and relations of production and implementation of innovations. Innovation plays a special role in improving the competitiveness of enterprises. Social innovations in the energy sector offer alternative development models and greater stakeholder participation, but there is a number of features in this type of innovation. In the current economic conditions, it is necessary to maximize efforts in the field of practical application of social innovation projects in the energy sector, a successful implementation of which provides opportunities for alternative development models and ensures the competitive attractiveness of business entities for both the consumer groups and investment infusions.
Identification and evaluation of the impact of uncertainty factors on the activities of agricultural enterprises
Authors: Sabetova T. V.
Published: March 2019

The article considers t the problem of determination of the degree of influence of uncertainty factors on the performance of an agricultural enterprise. Uncertainty and risk are an integral part of business life, and in agriculture they are all the more significant, since agricultural companies are greatly dependent on the influence of natural factors and phenomena. Consequently, the assessment of the directions and the strength of the impact of risk factors is of great importance for the plans and projects for the company's activities. After carrying out a schematic factor analysis of the financial results of the agricultural enterprise, the author selected parameters such as crop yields and average selling price, for analyzing the degree of exposure to uncertain factors. Since both the selected parameters are affected by a large number of both certain factors and factors uncontrollable for the company's management, the author finds it unacceptable to apply factor analysis to them. In the first place, the author justifies this by the difficulty in determining the weights of each influencing factor. Instead, the author suggests grouping all the factors on the basis of their certainty and definition of the influence degree for each group. For this purpose, the variability of each parameter in different series was analyzed: for several years in one enterprise and for one year in a number of similar enterprises. It was found that fluctuations in crop yields by enterprises were higher than by years. This forced the author to bring out the conclusion that there is a significantly greater influence of certain factors on this indicator. On the other hand, when analyzing prices, the opposite situation emerged: here the influence of uncertain factors is much stronger. As a result, the proposal was made for the projecting method, such as economic and mathematical modeling, to use the data from both the firm being the subject of modeling, and from the similar enterprises available from the regional Department of Agriculture. In this case, the accuracy of the forecast will be much higher, besides, it can be developed in 3 or 5 probability scenarios.
Competitiveness Management of Goods Based on the Application of the Theory of Attractive Quality N. Kano (on the example of JSC “Sagunovsky Meat Processing Plant”)

The study substantiates the idea that the key task of managing competitiveness is the proof of the viability of the goods produced and the creation of conditions for the struggle for the consumer with the help of modern methods of ensuring customer satisfaction. Under these conditions, models of demand formalization and determining the competitiveness of products become particularly relevant. The Noriaka Kano model of attractiveness is considered, which makes it possible to single out the existing features of products of a particular manufacturer that are not found in competing analog products that could increase the competitiveness of the products studied. The article presents the results of a study of consumer satisfaction with meat products of OJSC “Sagunovsky Meat Processing Plant” by the method of N. Kano, identified factors that increase the attractiveness of products and the competitive advantages of an enterprise in the market. The authors compiled a questionnaire, which allowed to identify various degrees of satisfaction with the properties of the meat products of the plant. A feature of the content of the questionnaire questions was a combination of positive and negative questions, which made it possible to form the most complete picture of the attractiveness of the properties of meat products. The result of the processing of the obtained data was the calculation of the satisfaction and dissatisfaction potentials of consumers of the plant’s products and the mapping of characteristics. Products produced by the meat processing plant may have a high potential quality, i.e. Comply with state standart and generally accepted specifications, but high real quality is achieved only in the process of using the product and customer satisfaction. The study showed that in the company's strategy little attention is paid to improving the product line in the premium segment, as well as to those characteristics of meat products that are not directly related to the basic properties of the sausage, but make the consumer happy. The meat factory needs to reconsider approaches to the development and implementation of product policy, in particular, to revise the requirements for smell, cutting and high content of spices in sausage. The use of this model will allow the company to develop measures to increase the attractiveness of products and improve the strategy of product promotion on the market.
