Medicinal and flavoring herbs are widely used in herbal medicine. Various methods are used to study plants, evaluate the efficiency of extraction of biologically active target components. The process control is carried out by chromatographic, spectral methods. The search for new fast, affordable, simple methods of analysis is currently relevant. The dry droplet weighing method of the extract was proposed as an alternative to the known methods. The analysis of flavoring herb parsley extracts by four methods (spectrophotometry, refractometry, thin layer chromatography and direct dry drop weighing) was carried out. The objects of study were fresh protected ground parsley and the Indana brand dried parsley. Fresh parsley was dried and the change in the chemical composition of water-alcohol extracts was monitored for 16 days. Compounds in the extracts were identified by differential spectra. It was found out that the amount of substances extracted from the flavoring herb was greater than in the dry sample after 12 days of drying. The composition of the mobile phase for thin layer fast chromatography was selected. The best separation of chlorophylls from related substances occurs at a volume ratio of toluene and ethyl alcohol of 5:5 and 6:4. The sensitivity of the refractometry method does not allow determining the difference in the composition of fresh parsley extracts. Using the method of direct piezoquartz microweighing, it was proved that with an increase in the drying time of parsley, the number of compounds in a dry drop of the extract increases. The most sensitive method i.e. piezoquartz microweighing, the MCNano-WPQ-8 device can be used in non-laboratory conditions for express monitoring of plant materials drying in small manufactures. it is simpler, cheaper, more compact and more sensitive than other devices. The device and approach were tested on various types of phyto raw materials.

On the basis of official statistical data on the structure and existing risks of the formation of Russia's foreign trade turnover in comparison with other developed countries, the objective need for import substitution has been substantiated, the acceleration of which and an increase in the role in ensuring the country's economic growth depends not only on the effectiveness of measures taken by the state and the business community, but and from a clear quantitative assessment of its performance. A comprehensive assessment of the effectiveness of import substitution was carried out on the basis of a wide range of statistically reliable single indicators reflecting the impact of import substitution on the state and dynamics of development of the most important sectors of the national economy – its domestic production, exports, imports, and the socio-economic sphere. In order to model and calculate a complex indicator of the effectiveness of import substitution on the basis of the formed system of single indicators, the method of principal components was used, implemented in the Statistica application software package and which made it possible to compress the generated array of multidimensional information to a limited number of more informative features (the main component for each block of indicators) up to the final a comprehensive indicator of the effectiveness of import substitution. The indicators that have the greatest impact on the effectiveness of import substitution in each block of indicators have been identified. Based on the regression analysis, a high positive correlation was found between the integrated indicator of the effectiveness of import substitution and economic growth. Using the method of multicriteria optimization, the parameters of import substitution have been determined, which, in real economic conditions, at the prevailing rates and scales of GDP, enhance the positive impact of import substitution on economic growth.

A resource-saving technology for processing apples, including the main production of finished dried products in the form of dried apples, apple chips, apple semi-finished products and additional production based on secondary raw materials recovery from the main production, were proposed in the work. The possibility of using of secondary raw materials from the apples industrial processing to obtain natural products that allows to make the main manufacture of dried apple products as efficient as possible was studied by the authors. The main directions of apples and secondary apple raw materials processing were considered in the work. The technological scheme of the line for apples and their wastes processing based on dehydration and moisture-thermal processing of components, taking into account the specifics of the production of dried fruits, chips and their semi-finished products, was proposed in the course of this study. The main production line for the manufacture of dried apples, apple chips and apple semi-finished products was designed. The resource-saving technological scheme of the dried apple and apple chips production line includes a washing machine, an inspection conveyor, a calibrator, a machine for seeds removing and a device for cutting fruits into chips, a sulfitator, a combined continuous toroidal apparatus for wet-heat treatment, divided into sections for raw materials heating, convective drying , preliminary hydrothermal treatment between sections of microwave drying and dried product cooling and a filling and packaging machine. Taking into account the type of raw materials, a set of equipment from a drum machine with a washing unit and a multifunctional plant with raw materials crushing and seeds separation was provided in the line. The recirculation circuit, the feedstock heating, the steam and condensate used after drying in a closed circuit were used to create an energy-saving technology for the finished product manufacturing. The line consists of modular blocks and is reconfigured depending on the type of dried apples or apple chips obtained based on the developed resource-saving scheme and combined convective microwave drying of raw materials.

The article deals with issues related to the mechanization of methods existing in Russian practice that allow assessing the level of influence on favorable conditions for the development of small innovative enterprises based on military institutions, and a new comprehensive indicator, which, when creating this database, is a general index of innovation. Based on two factors illustrating only opportunities for development and favorable conditions, and the true results of this activity, methods are proposed for predicting the importance of each element in terms of its impact on the level of innovative development, and, based on this, innovators are usually offered approaches to assigning weight modules to factors used in various methods of calculating the indicator. In the conditions of the current financial crisis, the reason for the success of small enterprises is the impact of their new development system and getting more opportunities for their functioning, to ensure a high level of planning of production processes in small companies. The author examines the Pleiades Correlation Graphs, which is formed based on the method of compiling a list of conditions that affect the development of small enterprises for small businesses based on military companies, to see how small enterprises are in transition. Thus, a methodology for the influence of favorable conditions on the development of small innovative enterprises based on military institutions is proposed, the choice of factors and the principle of assigning weight coefficients for them are substantiated, and a variant of the development of this methodology is shown. Further research is needed to obtain a more complete picture of the relationship between enabling environments and the development of small innovative enterprises based in military institutions.

Currently, there are high requirements for finished rubber products, in particular, for products that are operated in the Far North. The purpose of this work is to determine the optimal conditions for the production of nitrile butadiene rubbers, which provide an increase in the frost resistance of materials based on them while maintaining a high level of physical, mechanical and operational properties. The paper presents polymerization recipes and synthesis conditions. It was found that the fractional addition of acrylic acid nitrile and molecular weight regulator provide optimal conditions for obtaining synthetic rubber with the desired characteristics. The results of testing prototypes for chemical composition and physical and mechanical properties comply with the technical specifications for rubbers of the SKN-SNT brand. Rubbers and vulcanizates SKN 20SNT are the most promising for the creation of frost-oil-resistant products. Physical and mechanical tests have shown that the vulcanizate of the SKN 15SNT sample obtained under optimal synthesis conditions has a tensile strength of 22.7 MPa, an elongation at break of 485%, and a frost resistance coefficient of 0.84. It was also found that the vulcanizate of the SKN 20SNT sample, obtained under optimal synthesis conditions, has a tensile strength of 24.0 MPa, an elongation at break of 478%, and a frost resistance coefficient of 0.61. An increase in the oil and petrol resistance of frost-resistant rubbers and SKN 15SNT vulcanizates can be realized by controlled crosslinking of rubber polymer chains at the polymerization stage. The continuation of this work will be extended tests of prototypes SKN 15SNT and SKN 20SNT in order to determine such indicators as glass transition temperature, average molecular weight, molecular weight distribution, degree of polydispersity, gel content, compositional uniformity, etc.

The work is devoted to the filling of PVC (polyvinyl chloride) compositions modified with ABS (acrylonitrile-butadiene styrene) in a wide concentration range, intended for the production of profiles and moldings of various functional purposes, with short-fiber basalt fiber. Powdered samples were made by extrusion (in the form of flat profiles) and by thermoplasticizing on rolls (in the form of films). Introduction of 10-40 phr ABS in PVC formulation makes it easier to recycle the composition. Similar situation is observed when these compositions are filled with basalt fiber, which leads to insignificant decrease of MFR (melt flow index) and thermal stability, which in general does not reflect negatively on melt flow conditions, at the same time extrudate swelling index decreases by 10-15%, which indicates possibility to provide products with more precise geometric dimensions. The change in the supramolecular structure was evaluated by thermomechanical tests and by energy dispersive analysis using electron microscopy data. Thermomechanical analysis showed that the presence of large doses of ABS has a positive effect on the technological properties, leading to an earlier development of highly elastic deformations and a decrease in the yield point of the compositions. Basalt fiber contributes to an insignificant decrease in the value of high elastic deformations and an increase in the density index of meshing knots. Energy dispersion analysis has shown that introduction of basalt fiber leads to formation of homogeneous structure of PVC at lower concentrations of ABS in the composition, influencing on increase of melt flowability and thermal stability. Improved technological properties of PVC compositions filled with short-fiber basalt fiber, modified with different concentrations of ABS, allow to recommend them for production of a wide range of profile and molded products.

Since each subject of the Russian Federation has full rights to conduct both interregional and international economic relations, the indicators of regional development largely depend on the investment strategy being implemented, including the level of investment potential. In this regard, the article deals with the urgent task of assessing the investment potential of the region based on socio-economic indicators using mathematical statistics, which allows us to obtain objective and reliable results, and also ensures the scalability of the methodology used and the possibility of its application to analyze the investment potential of other regions of the Russian Federation. Correlation and regression analysis was used, a linear regression model was studied for multicollinearity. The use of multidimensional statistical analysis of the investment attractiveness indicators of the Orenburg region allowed us to identify the most significant factors influencing the volume of investments in the fixed capital of the region, which include: the amount of work performed by the type of economic activity "Construction"; average per capita monetary income of the population; the volume of manufacturing production; the proportion of the working-age population in the total number. Based on the results of correlation and regression analysis, it is concluded that the level of investment in fixed assets of the Orenburg region is most significantly influenced by such areas of economic activity as agriculture, mining and manufacturing. Attracting investments to the identified sectoral priorities of the investment attractiveness of the Orenburg region will ensure the creation of high-performance places in the region, increase the gross regional product, and also give a multiplier effect for the development of other activities.

The article is devoted to the systematization of scientific developments of domestic scientists in the sphere of oilseeds flax processing and their use in technologies of flour products. Oilseed flax is the only oilseed crop in which almost all anatomical parts are important for industrial processing. The use of oil flax in the food industry is due not only to the presence of biologically valuable nutrients, but also to the functional and technological properties inherent in the products of their processing. It is shown that along with whole and ground flax seeds, not only flax seeds processing products (full-fat, semi-fattened, skimmed and oil), but also bran and cryopowder from seeds are widely used in the above food technologies. Flax seed hydrocolloids or dry polysaccharide extract deserve special attention, which are of interest not only from the technological point of view (analog of xanthan gum, guar gum), but also from the medical and biological position, since they perform prebiotic function in the human body. Analysis of numerous domestic sources of scientific, technical and patent information allows us to conclude that flax seeds are, on the one hand, a well-known and widely used raw material.

Oilseed flax is the only oilseed crop in which almost all anatomical parts are important for industrial processing. The use of oil flax in the food industry is due not only to the presence of biologically valuable nutrients, but also to the functional and technological properties inherent in the products of their processing. It is shown that along with whole and ground flax seeds, not only flax seeds processing products (full-fat, semi-fattened, skimmed and oil), but also bran and cryopowder from seeds are widely used in the above food technologies. Flax seed hydrocolloids or dry polysaccharide extract deserve special attention, which are of interest not only from the technological point of view (analog of xanthan gum, guar gum), but also from the medical and biological position, since they perform prebiotic function in the human body. Analysis of numerous domestic sources of scientific, technical and patent information allows us to conclude that flax seeds are, on the one hand, a well-known and widely used raw material.

The paper considers the possibility of using highly dispersed modified aluminosilicates in the process of extracting hydrogen sulfide from wastewater. The problem of the presence of hydrogen sulfide in natural waters is due to the impossibility of using such waters in human household activities. Water with a high content of hydrogen sulphide has low organoleptic properties, is not suitable for consumption and is highly corrosive. Produced water generated in the process of oil production must also be treated. In the presence of hydrogen sulphide in the produced water, further water injection into the reservoir is highly discouraged, as this can lead to "plugging" of oil-bearing channels. In this regard, the work proposes a method for extracting hydrogen sulfide from natural and waste waters. The work synthesized a new adsorption-coagulation material based on modified aluminosilicates (bentonite clays) using salts of multivalent metals. The possibility of creating a reagent with a different ratio of aluminosilicate matrix: modifier is considered. It was found that the efficiency of the reagent increases with an increase in the pH of the medium. The activity of the reagent in relation to hydrogen sulfide, clarification and removal of oil products was studied. The capacity of the reagents obtained as a result of the modification can reach 32 mg/g in terms of hydrogen sulfide. In the reagent, it is possible to vary the ratio of aluminosilicates and modifiers, which can facilitate the use of the most effective reagent, depending on the conditions. The reagent is capable of extracting not only hydrogen sulfide, but also oil products from the processed aqueous solutions. The reagent binds hydrogen sulfide into insoluble forms, after which the precipitate can be separated from the solution and disposed of.

Amidomineral granulated beet pulp is a product that can be used as a compound feed for feeding cattle, and as a feed additive in the production of compound feeds. Amidomineral granulated beet pulp, compared with fresh and dry pulp, is richer and saturated with various additives that will positively affect the appetite and weight gain of animals. Amidomineral beet pulp, in order to improve transportation and storage, makes sense in granulation. Thus, mathematical methods of experiment planning are used to study the interaction of various factors affecting the process of granulation of amidomineral beet pulp. A mathematical description of this process can be obtained empirically. At the same time, his mathematical model has the form of a regression equation found by statistical methods based on experiments. As a result of statistical processing of experimental data, regression equations were obtained that adequately describe the process of granulation of amidomineral beet pulp in the B6-DVG granulator. As a result of the conducted research, the modernization of this equipment is proposed.
