Для обеспечения точности измерения показателей преломления жидкостей, качество которых определяется, все рефрактометрические средства измерений (РСИ) проходят процедуру калибровки для снижения погрешности градуирования, которая составляет до 70 % основной погрешности. В отдельных случаях требуется проводить процедуру калибровки в идеальных условиях, не допуская резких перепадов температуры, так как у жидкостей при повышении температуры значение показателя преломления уменьшается, а при понижении - увеличивается. Сложность и большая длительность процедуры калибровки снижает ценность известных РСИ. Цель исследования - снижение основной погрешности нового волоконно-оптического рефрактометрического датчика (ВОРД), реализующего модифицированный рефрактометрический способ диагностики качества жидкостных сред различного применения. Результаты. Доказано, что применение сначала прозрачного калибровочного вещества с известным коэффициентом преломления, помещенного в цилиндрическую прозрачную микротрубку, а потом прозрачного исследуемого вещества с искомым коэффициентом преломления, позволяет изменить контур изображения излучающего торца подводящего оптического волокна в плоскости, где расположены приемные торцы отводящих оптических волокон, и, соответственно, изменить выходной сигнал датчика...

To ensure the accuracy of measuring the refractive indices of liquids, the quality of which is determined, all refractometric measuring instruments (RMI) undergo a calibration procedure to reduce the calibration error, which is up to 70 % of the basic error. In some cases, it is necessary to carry out the calibration procedure under ideal conditions, avoiding sudden temperature changes, since the refractive index of liquids decreases with increasing temperature, and increases with decreasing temperature. The complexity and long duration of the calibration procedure reduces the value of the known RMI. The aim of the study is to reduce the basic error of the new fiber-optic refractometric sensor (FORS), which implements a modified refractometric method for diagnosing the quality of liquid media of various applications. Results. It is proved that the use of first a transparent calibration substance with a known refractive index placed in a cylindrical transparent microtubule, and then a transparent test substance with the desired refractive index, allows you to change the contour of the image of the radiating end of the incoming optical fiber in the plane where the receiving ends of the outgoing optical fibers are located, and, accordingly, change the output signal of the sensor...

Authors: Korobeynikov D. A. , Korabelnikov I. S. , Telekabel V. K.
Published: January 2025

In the agricultural sector of Russia, an independent market of digital platforms and ecosystems is actively developing, which leads to a variety of their organisational forms and differentiation of business models.

   The purposes of the study are to develop classification criteria and, on their basis, form a typology of existing platform and ecosystem decisions in the Russian agro-industrial complex.

   The following classification criteria are proposed: role of the ecosystem core in business, industry localization, and product specialisation. According to the first criterion, all ecosystems are divided into core companies complementary to the main business and independent ones. According to the second criterion, they are divided into universal and industry-specific, while the latter can be part of the universal ones. Considering the third criterion, the following elements are identified and described in detail: specialised product marketplaces (B2B (business-to-business) for wholesale, B2B and B2C (business-to-customer) for retail, B2B for supply, B2B for procurement and mixed ones); logistics platforms; financial platforms and aggregator sites. Emerging multi-functional industry ecosystems offering comprehensive products for agribusiness are separately highlighted as well as government services and platforms implementing individual functions of government administration in the industry.

Authors: Makhalina O. M. , Mahalin V. N.
Published: January 2025

The Russian science, according to the existing scientific resources, occupies leading places on many positions, demonstrates serious achievements in many fields, but low overall effectiveness. In the development of science, systemic problems are manifested due to numerous factors, the most important of which are considered in the work. The analysis of the modern development of science has revealed its main challenges. Special attention is paid to the problems of staffing the scientific and technical complex and identifying the causes of the decline in the scientist’s prestige. In Russia, the number of personnel employed in science has been constantly decreasing for many years. The number of postgraduates and doctoral students as well as the amount of dissertation defenses, has decreased 4–7 times over the past four years, and the age structure of the scientific staff has been deformed. The popularity of the scientist has decreased several times. Based on the analysis, the main factors of declining popularity are identified in the work: profession of the scientist is not prestigious; there is a low salary level; there are no mechanisms for popularising the profession; there is no qualitative assessment of the scientist’s work. Proposals for staffing scientific activities and increasing the prestige of the scientist’s work are formulated: increase of the cost of science; elimination of the problem of the scientific personnel’s aging; significant increase in the material support of the scientific personnel; expansion of the possibilities of using grant financing for basic research. Special attention is paid to solving the tasks of improving scientific activity, which are formulated in national projects.

The reasons for the shortage of qualified specialists are analysed, which include both positive factors (rapid economic development and technological changes) and negative ones (demographic changes, industry characteristics, imbalance in the labour market and migration). Statistical data on the level of unemployment, migration, and population structure are provided, which makes it possible to identify the main trends and predict the further development of the situation in the labour market. Particular attention is paid to the problem of migration of graduates of higher educational institutions and their impact on the economy of the region. The article also examines the impact of international and interregional migration on the labour market and demographic situation in the region. Possible ways to solve the problem of the personnel shortage are discussed, including improving the material and technical base of educational institutions, adapting educational programmes to the requirements of the labour market, and introducing a multi-level system of control over the migration. The proposed measures are aimed at creating conditions for attracting and retaining the qualified specialists in the region, which in turn will contribute to its sustainable economic development.
Regional investment standard as a tool for increasing the effectiveness of investment project implementation
Authors: Nadyrgaliev Ye. T.
Published: January 2025

This article discusses the need to create favourable conditions for investment, especially in the industrial production sector, as a critical element in reducing territorial inequality and raising the standard of living in the country. In the context of economic sanctions and limited financial capabilities of companies, achieving technological and product sovereignty is impossible without a significant increase in the investment in production. The main objective of the study is to develop a methodology for assessing the effectiveness of the regional investment standard (herein-after referred to as RIS) and its impact on the growth of the industrial production and profitability of companies. The article proposes two key tools: coefficient of investment impact on the industrial production and coefficient of investment profitability. A correlation analysis has also been conducted which, although demonstrating a low degree of dependence between the magnitude of the RIS implementation and performance indicators, points to future improvement in dynamics as investment procedures are improved. The conclusion notes that the correct methodology and its use can significantly increase the level of investment projects and stimulate economic growth in the regions. The study is based on the data of the Federal State Statistics Service on the investments in non-financial assets.

Authors: Popadyuk N. K.
Published: January 2025

The subject of the study is the search for mechanisms of financial and economic regulation of the development of urban agglomeration, which, due to the chronic insufficiency of funds for these purposes of municipal budgets, is of particular importance.

   The purpose of the work is to justify the need to use non-traditional tools for regulating the coordinated development of municipalities forming the urban agglomeration.

   At the same time, it is shown that not only state regional government and municipal self-government bodies are the subjects of economic activity in each urban agglomeration: among them there are quite independent economic entities that need to be invited on the principles of public-private and municipal-private partnership to participate in the coordinated management of the development of the entire agglomeration in the interests of all stakeholders. The study is conducted on the basis of generalisation of the literature on the analysis of the methods used to manage the development of the urban agglomerations. Publications in which the analysed problems found forms of their resolution are the sources of information. The results of the study have heuristic potential due to the possibility of using the considered tools for financing the development of agglomeration for the coordinated development of the municipalities that do not form the urban agglomeration.

   The possibility of applying non-traditional forms of financing the coordinated development by increasing the capitalisation of municipal assets is the conclusion of the study.

   The relevance of the considered topic is due to the need to ensure the use of the entire arsenal of market instruments for purposeful development of the municipalities at a new stage of state development.

Metavalent materials: Compounds with partial σ bonds and low ionic character
Authors: Chakkingal Parambil Priyakumari , Jhaa Gaurav , Kumari Mithu
Published: January 2025

The term metavalent bonding was introduced recently to describe bonds that are in between metallic and covalent. They are characterized by nearly half bond order, large Born Effective Charge (BEC), low band gap, moderate electrical conductivity and large optical dielectric constant. While the presence of large BEC, half-bond order and low band gap are often highlighted as their striking features, chemists are familiar with half-bond order systems, and hence there is a reluctance to consider metavalency as a new bonding mechanism. Here we use molecular orbital theory and DFT calculations to identify the uniqueness in the bonding in known metavalent materials and compare that with hypervalent half-bond order systems that are not classified as metavalent. We show that the metavalent materials are compounds with partial σ bonds and low ionicity. If such systems have low band gaps either due to low bonding-antibonding splitting or due to delocalization, that result in large BEC. This suggests that metavalency is not a new bonding mechanism.

Published: January 2025

The development of efficient synthetic methods for α-boryl ureas and carbamates is of significant interest due to their potential as drug-like scaffolds in medicinal chemistry. This study presents a novel one-pot synthesis of α-boryl ureas and carbamates via α-boryl isocyanates, generated in situ from widely available α-haloboronates. The method leverages an in situ activation of trimethylsilyl isocyanate by sodium iodide to generate a more nucleophilic isocyanate species, facilitating the formation of α-boryl isocyanates under mild conditions. The broad substrate scope and functional group tolerance of this protocol enable the synthesis of diverse α-boryl ureas and carbamates, including biologically relevant molecules and late-stage pharmaceutical derivatives. To showcase the potential of this methodology in drug discovery, an α-boryl urea analog of nirmatrelvir, a SARS-CoV-2 main protease inhibitor, was synthesized, demonstrating enhanced potency (IC50 = 12 nM) compared to nirmatrelvir. This work not only offers a streamlined, direct approach for the preparation of synthetically challenging α-boryl ureas and carbamates with broad structural diversity, but also underscores the importance of α-boryl ureas as valuable scaffolds for the development of new therapeutics.

Efficiency evaluation of the milling process based on the granulometric analysis of crushed stone-mastic asphalt concrete granulate
Authors: Furmanov D. V. , Budanova E. S.
Published: January 2025

Introduction. The working process of milling asphalt concrete pavements. The working process of asphalt concrete milling is considered as a set of destruction processes of the stone fraction, bitumen bonds and other phenomena unrelated to the formation of new surfaces. The conducted analysis is based on the assessment of the ratio of energy spent on milling in general and the energy needed for the formation of new surfaces made from separate fractions of asphalt concrete granulate and crushed stone aggregate.

Materials and methods. The work is based on carried out experimental studies of the granulometric composition of asphalt concrete granulate obtained by milling crushed stone-mastic asphalt concrete pavement, and, separately, the stone fraction of asphalt concrete got by burning out a bitumen matrix. A standard method was also used to determine the specific energy of destruction of bitumen bonds when determining the fracture disruption resistance of a sample in tension while splitting.

Results. As a result of sieving, granulometric curves of the composition of asphalt concrete granulate and stone fraction were obtained. Calculation methods have determined the components of energy consumption for the formation of new surfaces made from asphalt concrete granulate and new surfaces from stone fraction.

Discussion and conclusion. At the end of the study, quantitative ratios of various fractions of asphalt concrete granulate of stone-mastic asphalt concrete formed during milling, as well as the crushing grade of stone fractions, were obtained. The specific energy consumption during the milling of asphalt concrete has been determined. It was found that the largest part of the energy during milling (64.7% for this study) is needed for the destruction of bitumen bonds. The vast majority of this energy is used for the formation of the fine granulate fraction. An insignificant part of the energy is spent on the destruction of the stone fraction. In general, the share of energy consumption aimed at the formation of new surfaces accounts for this study 66.14% of the total energy costs. The research development prospects of granulometric analysis for evaluating the effectiveness of the asphalt concrete milling process have been noted.

Published: January 2025

Introduction. Modern wheeled vehicles with electric and hybrid power plants are becoming more and more widespread. It is obvious that with the increasing number of wheeled vehicles with electric and hybrid power plants, there is a need to conduct a full-fledged and qualitative study of the working processes of wheeled vehicles both at the stages of production and fine-tuning at manufacturing enterprises, and in operating conditions at the service stations and other organizations. The research of the technical condition of a wheeled vehicle with electric and hybrid power plants with a classic layout of the power unit and transmission (front or rear axle drive) is quite possible to be conducted on existing stands. But when testing wheeled vehicles with electric and hybrid power plants with all-wheel drive or with an electric motor generator for each drive wheel, a problem arises due to the lack of methods and means to measure traction force on each wheel individually.

Materials and methods. This section provides an analysis of the possibilities of conducting a study of the technical condition of wheeled vehicles with electric and hybrid power plants on modern power and inertia stands that apply the principle of reversibility of motion.

Results. Methods have been developed to study the traction and dynamic properties of wheeled vehicles with electric and hybrid power plants, to implement it was proposed to use developed research stand complex, which includes a hybrid stand with control and measuring systems that allow to determine forces and power on the driving wheels of vehicles, as well as time and kinematic parameters of its functioning process. During the experimental studies, the results of Kia Soul EV and Toyota Prius NHW20 operation processes were obtained, their power and kinematic parameters were analyzed.

Conclusion. As a result of the study, it has been proved that in order to ensure highly informative and stable test modes of wheeled vehicle’s operation in the process of studying their traction and dynamic properties, it is necessary to use hybrid stands.
