Under the conditions of sanctions, many Russian industrial enterprises are faced with the acute issue of increasing competitiveness. However, its solution, unfortunately, largely goes beyond the scope of the activity of the enterprise itself, its management system, due to the increasingly complex global economic situation. Also the enterprises themselves often lack effective and efficient methods contributing to the system elaboration of the problem of competitiveness increase. It is proposed to solve the problem of increasing the competitiveness of Russian industrial enterprises in conditions of import substitution with the help of the formulated mechanism. It is a set of measures, through which the controlling system affects all the resources of the enterprise, as well as the controlled properties of the external environment. With the intention of implementing its competitive advantages.

Currently, the task of obtaining polyvinyl alcohol oligomers (PVA) is urgent to create functional materials of a new generation with specified properties. One of the methods of modification of PVS is ozonolysis, which has a number of advantages over other methods of oxidative degradation of polymers. The aim of the work is to evaluate the structural changes and physico–mechanical characteristics of film samples of PVS modified by ozonated oxidation. To carry out the oxidation process, a 5% aqueous solution of PVA brand 1799 was prepared. The ozone-oxygen mixture was obtained using an ozonizer of a known design. The oxidation of PVS was carried out in a glass thermostatically controlled flask at 70 ° C, blowing an ozone-oxygen mixture through an aqueous solution of PVS for 40 minutes. Sampling was carried out after 10, 20 and 40 minutes of oxidation. The films were obtained by irrigation followed by air drying, after which they were subjected to IR spectrometric analysis and strength indicators were determined. As a result of the study, it was found that the modification of PVA brand 1799 by ozonated oxidation in an aqueous medium is accompanied by the following change in IR spectrograms: in the region of 1400 - 1600 cm-1, a sharp decrease in the intensity of the peak corresponding to hydroxyl groups forming hydrogen bonds is observed for ozone-oxidized PVA, in the region of 1650 – 1700 cm-1, a pattern of decrease in intensity is noted the peak with an increase in the oxidation time of PVA with ozone, which indicates a decrease in the MM of the polymer as a result of oxidative degradation, in the region of 3400 – 3600 cm-1 marked a change in the nature of the spectrogram, which also indicates a change in the structure of hydrogen bonds in oxidized PVS; the physico-mechanical properties of film samples subjected to 40-minute ozonated oxidation of PVS change towards a decrease in both strength and elongation at break by an average of 4 times, the Young's modulus decreases by more than 3 times, and the stretching diagram changes character in the zone of highly elastic deformation (the intensity of stress growth decreases by 1.5-2 times as the film elongates during stretching) and the fracture zone (the diagram acquires a stepwise character without a sharp break), which is associated with a decrease in the molecular weight of the PVS, the acquisition of new functional groups, a change in the stereoregularity of the hydroxyl groups of the main polymer chains, an increase in amorphousness and a change in their relaxation time.
目前，制备具有特定性能的新一代功能材料迫切需要获得聚乙烯醇低聚物(PVA)。臭氧分解是改性PVS的方法之一，与其他聚合物氧化降解方法相比，臭氧分解具有许多优点。本研究的目的是评价臭氧氧化修饰的PVS薄膜样品的结构变化和物理力学特性。为了进行氧化过程，制备了5% PVA 1799的水溶液。使用已知设计的臭氧发生器获得臭氧-氧气混合物。PVS的氧化在70°C的玻璃恒温烧瓶中进行，将臭氧-氧气混合物吹过PVS水溶液40分钟。在氧化10、20和40分钟后取样。经冲洗、风干得到薄膜，对薄膜进行红外光谱分析并测定其强度指标。研究结果发现，在水介质中臭氧氧化对PVA 1799牌号进行改性后，其红外光谱图出现如下变化:在该地区1400 - 1600 cm - 1,峰的强度急剧降低相应的羟基形成氢键ozone-oxidized PVA观察到,在该地区1650 - 1700 cm - 1,强度下降的模式指出,峰值与PVA与臭氧的氧化时间的增加,这表明MM减少聚合物的氧化降解的结果,在该地区的3400 - 3600 cm - 1标志着一个谱图的性质的变化,这也表明氧化PVS中氢键结构发生了变化;经过40分钟臭氧氧化的PVS薄膜样品的物理力学性能变化为强度和断裂伸长率平均下降4倍，杨氏模量下降3倍以上;拉伸图在高弹性变形区(拉伸过程中应力增长强度随薄膜伸长而减小1.5-2倍)和断裂区(拉伸图呈现逐步变化特征，但没有急剧断裂)发生变化，这与PVS分子量的减小、新官能团的获得、主聚合物链羟基的立体规整性的改变有关。无定形性的增加和弛豫时间的改变。

Vegetable raw materials and their processed products are a source of necessary biologically active nutrients and are widely used in food production when creating functional and specialized nutrition products. Studies of the mineral profile of wild cranberry berries (Vaccinium oxycoccos) growing in the Republic of Karelia and berry processing products (juice and cake) with different methods of processing raw materials have been carried out. Studies of the mineral composition of fresh cranberry berries and their processed products obtained by various methods showed a high content of essential macro- and microelements in fresh berries, juices and cakes and allowed us to establish the regularity of migration and distribution of micronutrients depending on the method of pre-processing of raw materials. The data obtained during the experiment allow us to judge the high mineral profile of wild cranberry berries and its processed products and the content of certain elements (in particular phosphorus and manganese) in a physiologically significant amount, which explains the prospect of using products of processing wild berry raw materials to enrich food with micronutrients. Studies of the mineral composition of edible packaging films based on concentrated cranberry juice have shown a higher mineral profile of all samples of films with the addition of juice obtained with pretreatment of berry raw materials with steam, regardless of the type of structure-forming matrix, which is due to a higher content of concentrated juice solids. It has been established that the pre-processing of berry raw materials with steam before extracting the juice, as well as its subsequent concentration, allows processing raw materials with maximum preservation of essential components with a high degree of biological activity.)

The number of commercial transactions in the digital segment, as well as the number of new products on the market, is growing from year to year. The intensification of innovation observed in the market indicates a reduction in the time of the release of a new product, which increases the supply in the market. However, a wide product range does not always allow companies to get their target audience, which leads to a decrease in the efficiency of the company and a reduction in sales. The intensification of the development of new products forces the manufacturer to improve marketing activities at the output stage. The article clarifies the concept of a new product through a terminological analysis of domestic and foreign sources. For a refined definition, marketing tools were identified at the stage of bringing the product to the market and existing marketing models that describe the diffusion of innovations. An attempt was made to combine the model of E. Rogers and F. Bass with the product life cycle model, which made it possible to draw conclusions regarding marketing activities and the tools used when launching a product in relation to the target audience of a new product. The article analyzed the definition of "new product" in the context of bringing a new product to the market. For a refined definition, conclusions were drawn and made regarding the strategies for entering the market and the marketing tools used in their withdrawal. Not only the strategy and consumer orientation are determined, but also the role of the consumer in bringing a new product to the market, taking into account the E. Rogers innovation diffusion model, the F. Bass model and the product life cycle model.

Merchandising, as one of the branches of marketing, is currently a rapidly developing field. It is noted that this term is approaching in number of formulations to the multi-valued term "quality". The authors of the article consider the concept of "merchandising" of goods. A general classification of merchandising (manufacturer and seller) is given, as well as its types (category and visual). The main techniques of merchandising include the following types: manipulating the flow of store visitors; positioning shelves; allocating limited space between competing offerings; using materials at the point of sale and installing special displays. It is noted that the consumer receives up to 80...86% of information through the most important sensory modality - vision. Due to the understanding of the importance of vision and sense of aesthetics and taste in merchandising has appeared a whole separate area - visual merchandising. This article discusses 25 types of POS materials ("Points of Sale Materials"). These include advertising wobblers, shelf talkers, hardposters, teabaggers, dorhangers, jumbies, magnetic bookmarks, nekhengers, menhoders and others. Examples are given of the use of basic merchandising principles in practice: bierdeckel - as an active advertising of the institution and drinks; the location of posters (or billboards) in front of the entrance to the public catering establishment; advertising stands in retail outlets for consumer appreciation of new foods; moulage dishes or popular products to attract consumer attention in stores, catering establishments and exhibitions; life-size figures, etc. POS materials should be aimed at performing five steps or stages of sale in terms of influencing the customer: attracting attention, arouse interest, creating desire, building confidence and direction of action. It is noted that the effective promotion of goods, works and services is possible only when the implementation of merchandising principles are approached from the positions of a systematic approach, which includes methodological work on teaching and training of specialists, merchandisers

In mathematical modeling of membrane processes, the study of structural features of used membranes and the significant limitation of information in the formal description of their separation properties led to the development of physical models that take into account not only the features of structures of real membranes, but also their peculiarities of functioning. When compiling physical models of membrane processes, it is impossible to objectively quantify most of the factors due to their great diversity and variability, which distances the mathematical model from the real process. That is why methods of computational fluid dynamics reliably and efficiently perform calculations for all physical models and types, including stationary or transient flow, incompressible or compressible flow (from small subsonic to hypersonic), simulation of laminar or turbulent flows, Newtonian or non-Newtonian fluids, ideal or real gas. An electronic geometric model of the plant was built, a choice of mesh geometry with different densities was made to optimize the calculation time and solution accuracy for a particular case, the kinetic dependence of cell growth was calculated, the flow rates of feeding medium into the intra- and inter-fiber spaces of the bioreactor were determined, and the hydrodynamic conditions were analyzed.

The purpose of the work is to study the possibilities of improving financial literacy and economic culture, behavioral economics in conjunction with solving the problems of sustainable development in the economic, environmental and social spheres. The apparatus of "behavioral economics" is applied as a theoretical paradigm that takes into account "psychology" to analyze the behavior of subjects of industrial relations. In the work, the author links financial literacy, behavioral economics, economic culture with the problems of sustainable development, and also reveals the conditionality of this development by the need to increase: the culture of thinking, comprehension of moral values, the level of rational consumption. According to the research hypothesis, the solution of these problems is largely due to the quality of the content of the education and enlightenment system. Financial literacy is considered as a condition for increasing the culture of consumption. The research methodology is based on a dialectical approach, an inductive-deductive method, a descriptive analysis of the fundamentals of the behavior of economic agents: theoretical principles of rational choice (maximizing utility) and observed deviations from rational behavior (limited rationality, behavioral effects and systematic errors associated with them); consumer culture, etc. Projects to improve financial literacy in the higher education system are considered as an educational environment that should be used to form predicative thinking, increase economic culture, culture of thinking, financial literacy, consumer culture, as important components in achieving sustainable development. The author concludes that increasing the financial literacy of the population contributes to an increase in the culture of consumption, which consists in satisfying the natural needs of a person as opposed to irrational behavior and degradation-parasitic consumption, which not only lead to losses in the personal budget, but also increase the destruction of natural resources and the destruction of the biosphere. As a result, it is proposed to supplement the program of improving economic culture conducted by national institutions with the topic of improving consumer culture, to expand the content of the general cultural competencies of the Federal State Educational Institution with a more complete knowledge of dialectics, moral value orientations, and the ability of predicative thinking

As a result, it is proposed to supplement the program of improving economic culture conducted by national institutions with the topic of improving consumer culture, to expand the content of the general cultural competencies of the Federal State Educational Institution with a more complete knowledge of dialectics, moral value orientations, and the ability of predicative thinking","PeriodicalId":31207,"journal":{"name":"Vestnik Voronezskogo Gosudarstvennogo Universiteta Inzenernyh Tehnologij","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135554239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For a long time, auditing has been considered a discipline dedicated to the evaluation of financial and accounting information. Today, he has demonstrated his strengths in various areas of business, including the social component, the practice of social audit or its origin, but this discipline remains limited, despite its importance for human resource management. This article discusses social audit as an anti-crisis management tool. Modern social audit has methods that allow us to give a fairly accurate and objective description of the potential of the management body and to identify its real ability to innovate. And they allow you to have a positive impact on the risks associated with human resources management. The main purpose of this publication is to summarize a review of the literature on social auditing and its impact on human resource management risk management. The implementation of a human resource management tool, which is considered the key to socio-economic efficiency and human capital adaptation, is highlighted as a paramount task, despite the fact that most companies do not choose this practice. Based on the results of the analysis of bibliographic materials, it was found that social audit: has a positive impact on the practice of managing risks associated with human resource management; seen as an effective tool for identifying positive social and emotional indicators of improving social performance; the importance of social audit in the enterprise and its role in minimizing crises associated with personnel practices.

The article discusses issues related to the study of the forms of connection of moisture removed during the drying process in black currant fruits. A study was carried out to determine the quantitative moisture content of various forms of communication by two methods and a comparative analysis was carried out. It is shown that the existing methods for studying the forms of moisture-material bonding have significant drawbacks and generally give a qualitative assessment of the state of moisture in the material or are very laborious and require long-term laboratory studies. The efficiency of the approach to determining the forms of moisture connection in black currant fruits is shown on the basis of graphical-analytical analysis of the drying kinetics, which allows qualitatively and quantitatively assessing the state of moisture in the fruits. With the help of a graphical editor, the curves of the drying kinetics of black currant fruits were processed and the dependences of the quantity called "drying acceleration" characterizing the rapidity of the change in the drying rate of currant fruits on the moisture content of the product were obtained. The analysis of the obtained curves is carried out, indicating the presence of extrema and points of inflection to the corresponding critical moisture content, as well as the presence of areas with a slowdown or acceleration of the drying rate change, allowing to establish the intervals of moisture removal with different binding energies. The approach under consideration makes it possible to give a quantitative and qualitative assessment of the physical state of moisture not only in currant fruits, but also in other food products, as well as reduce the time for analysis and improve the accuracy of the results.

The performance characteristics of composite materials reinforced with polyacrylonitrile technical flagellum (PAN-TF), which has the reactivity of functional groups, can be improved by modifying it. The aim of the work was to study the effect of polyacrylonitrile fibrous materials, applied with AGM-9, A-187, A-174 and Duron OS 3151 modifiers, on the kinetics of the ED-20 epoxy resin curing process, structural features of the developed composites and their operational properties. The methods of kinetic research, differential scanning calorimetry (DSC), scanning electron microscopy and mechanical testing of composite materials were used in the work. The effect of modified PAN-TF on the change in the kinetics of the curing process of the epoxy binder is shown, characterized by an increase in the curing time, a decrease in the maximum curing temperature and a decrease in the activation energy of the curing ED-20. The results of kinetic studies are confirmed by the data of DSC epoxy compositions based on modified PAN-TF, which show a decrease in the maximum temperature and an increase in the thermal effects of the ED-20 curing process in the presence of the studied reinforcing systems compared with epoxy composite reinforced with unmodified flagellum. The structure formation of epoxy compositions under milder conditions ensures the formation of a contact zone between the elementary fibers and the binder, which contributes to an increase in the solidity of plastics compared to a composite based on the original PAN-TF. A comparative analysis of the strength properties of the studied composites showed that when applied to ED-20, there is an improvement in strength indicators. The assessment of kinetic parameters, structural features and strength properties of the developed composites reinforced with modified PAN-TF indicates an increase in the surface activity of fibrous materials as a result of their modification.
具有官能团反应性的聚丙烯腈技术鞭毛(PAN-TF)增强复合材料的性能可以通过改性得到改善。研究了AGM-9、A-187、A-174和Duron OS 3151改性剂对聚丙烯腈纤维材料ED-20环氧树脂固化过程动力学、复合材料结构特征和使用性能的影响。采用了动力学研究、差示扫描量热法(DSC)、扫描电镜和复合材料力学性能测试等方法。改性PAN-TF对环氧粘合剂固化过程动力学变化的影响，表现为固化时间增加，最高固化温度降低，固化ED-20的活化能降低。动力学研究的结果得到了基于改性PAN-TF的环氧复合材料DSC数据的证实，表明与未改性鞭毛增强的环氧复合材料相比，有改性PAN-TF的环氧复合材料在ED-20固化过程中最高温度降低，热效应增加。在较温和的条件下，环氧树脂组合物的结构形成确保了初级纤维和粘合剂之间形成接触区，与基于原始PAN-TF的复合材料相比，这有助于增加塑料的固体性。对所研究的复合材料的强度性能进行对比分析表明，应用于ED-20后，其强度指标均有改善。对改性PAN-TF增强复合材料的动力学参数、结构特征和强度性能进行了评价，结果表明改性后纤维材料的表面活性有所提高。
