Authors: Kiss Imre
Published: November 2021

The objectives of this research is to study and understand the nodulizing of ductile iron using in-ladle treatment process. Among the more common nodulizing agents is magnesium (Mg) which is conventionally added to the cast iron by combining suitable alloys of one or both of these elements with molten cast iron. Depending on the characteristics of each master alloy used as nodulizer, different treatment methods and techniques are used, among these, the most widely used being in-ladle, in-mould, and flow-through, the first being the most used. This research deals with the parameters, that affect the quality of ductile iron produced using in-ladle treatment process. The parameters involved are the percentage of magnesium–ferrosilicon (Fe–Si–Mg) used and the nodulizing technique. In-ladle treatment used consists of a deep pocket into the bottom of ladle, in which magnesium–ferrosilicon is placed into it together with a steel scrap barrier (steel sheets) or calcium carbide. This study, take into account, the degree of assimilation of magnesium, which shows the performance of the chosen process, depending on the nodulizer used and the temperature of the treatment.

Authors: Breški Tomislav , Hentschel Lukas , Godec Damir , Đuretek Ivica
Published: November 2021

Fused filament fabrication (FFF) is currently one of the most popular additive manufacturing processes due to its simplicity and low running and material costs. Support structures, which are necessary for overhanging surfaces during production, in most cases need to be manually removed and as such, they become waste material. In this paper, experimental approach is utilised in order to assess suitability of recycling support structures into recycled filament for FFF process. Mechanical properties of standardized specimens made from recycled polylactic acid (PLA) filament as well as influence of layer height and infill density on those properties were investigated. Optimal printing parameters for recycled PLA filaments are determined with Design of Experiment methods (DOE).
China’s trade and economic relations with Algeria, Morocco, and Mauritania in the 21st century
Authors: Kravtsov Kirill S.
Published: November 2021

The study analyzes the current level of China's trade and economic relations with Algeria, Morocco, and Mauritania. The research methods include comparative-historical and economic analysis with the use of trade intensity and trade complementarity indices.
The author concluded that Algeria enjoys a leading position in terms of trade flows between the countries and investment from China. Morocco is in the second place in terms of trade turnover, while Mauritania has the smallest volume. The most diversified trade is between the PRC and Morocco, as there is not only the mineral sector (as in the case of the other two countries), but also the services and electronics sectors. Traditional areas of trade and economic cooperation in the field of mining have demonstrated a low level of trade complementarity for the China-Algeria, China-Mauritania pairs. The most promising industries, according to the results of the study, are China’s machinery, the service sector and agriculture.
The intensity of trade flows was higher in the period 2010-2019 on the part of the PRC in the China-Algeria, China-Morocco pairs. The disparity in the intensity of trade progressed throughout the period for the China-Algeria pair, while the intensity remained the same for the China-Morocco pair. Mauritaniais the country with the highest trade intensity index with the PRC. Moreover, the intensity on the part of Mauritania was higher than on the part of the PRC throughout the entire period.
The data obtained confirmed the importance of the region in China's foreign trade relations, a trend that may develop in the future.
New offensive strategy of Washington and Tokyo in the APR
Authors: Gordeeva Irina V.
Published: November 2021

The article is devoted to an important and topical issue - the advancement by the new American administration of an offensive strategy in the Asia-Pacific region (APR), aimed at ensuring the leading role in the region of the United States and its allies and applying, if necessary, the use of force. This strategy has led to a serious shift in the overall situation in the region and to rising tensions. The main target of this strategy is China, which is claimed to be "the only competitor capable of presenting a real challenge to a stable and open international system".
On the one hand, China in recent years has become an important economical partner to the countries of the APR, but its rapid growth and “assertive policy undermining existing status-quo” raised, as it stated by Washington and Tokyo,great anxiety.  A special role in the U.S. policy is given to Japan, which has taken a course towards further strengthening the Japanese-American alliance and enhancing its role in the affairs inthe region and on the world stage.
The concept of a "Free and Open Indo-Pacific region" (FOIP) has been put forward by Washington and Tokyo, as their central strategic doctrine. An important component of this policy is a significant build-up of military efforts by these countries in the APR - in the context of the confrontation with Beijing. Although the situation is reallydangerous and the parties will have to reckon with new circumstances, carefully calibrating their actions, however, each of them, as expected, will try to avoid a direct armed clash that could have unpredictable consequences.
Existing practice and risks of malicious use of artificial intelligence in Sub-Saharan Africa
Authors: Pantserev Konstantin A.
Published: November 2021

The necessity of the development of advanced technologies is considering as the essential condition for the ensuring of the world leadership in the contemporary world. But the rapid growth of such technologies and their implementation into all spheres of our life increase the risk of their malicious use in the future. African countries are no exception in this regard. They regularly become victims of cyber-attacks, which every year become more and more high-tech.
There has been undertaken in the article the analysis of the existing practice and risks of malicious use of advanced technologies in Sub-Saharan Africa. The author notes that today the banking sector is most exposed to cyber-attacks. But advanced technologies are gradually beginning to be used also for the mind management and creating the public opinion convenient for perpetrators who are aimed on the increase of social tension in certain countries or the entire regions. Undoubtedly even the possibility of such attacks poses a very serious threat to international information and psychological security. Finally, the author comes to the conclusion that African countries should develop effective supranational instruments aimed at improving their information security and preventing further malicious use of advanced technologies. Until this happens, it seems unlikely that African countries will even come close to solving the problem of ensuring their information security. So their information space will continue to be subjected to large-scale cyber-attacks that pose a serious threat not only to the security of individuals, but also to the entire national security system of the state.

Mediación violenta y construcción de poderes regionales: la violencia homicida en la ciudad-región
Authors: Martínez Herrera Luis Adolfo
Published: November 2021

Los procesos transicionales instauran la promesa de la fractura ante las dinámicas violentas, esbozan imaginarios sociales de transformación de las dinámicas antidemocráticas, y con ello dibujan el tránsito hacia sociedades más seguras, democráticas y estables. Pero esta promesa encuentra una ilusión adicional en aquellos regímenes sociales que han ocultado de manera histórica dinámicas de exclusión y violencia homicida, con la intención de promover dinámicas de desarrollo regional que necesitan construir la ilusión de la ausencia de conflictos y mediaciones violentas. El eje cafetero en Colombia esboza de manera clara esta doble irrealidad; por un lado, un conflicto social y armado minimizado en aras de favorecer dinámicas comerciales, industriales y de servicios; por el otro, una transición precariamente asumida ante dinámicas históricas de unas mediaciones violentas que le han dado forma a lógicas de autoridad y órdenes sociales casuísticos. El presente capítulo analiza las dinámicas históricas de violencias homicidas en una de las regiones del eje cafetero, como lo es Risaralda y su capital Pereira, que ha crecido bajo el imaginario social de progreso y civismo, casi ausente del conflicto armado experimentado en el contexto colombiano. La lectura comparativa entre violencias homicidas en Pereira (interpretada como ciudad-región) respecto al contexto nacional señalan todo lo contrario: una violencia endémica con altos niveles de letalidad se ha instaurado bajo unos modelos de desarrollo regional que se integran a los ritmos de las violencias homicidas.

STUDY OF THE EFFECT OF PLASTIC DEFORMATION ON THE CRYSTALLOGRAPHIC TEXTURE AND ACOUSTIC CHARACTERISTICS OF LOW-ALLOY STEEL
Authors: Mishakin V.V. , Gonchar A.V. , Klushnikov V.A. , Kurashkin K.V.
Published: November 2021

he article presents the results of a study of the influence of plastic deformation on the change in the coefficients of the orientation distribution function (ODF) W400 and W420 of low-alloy steel 09G2S. To calculate the ODF coefficients, the velocities and times of propagation of shear and longitudinal bulk elastic waves and their ratios were used. The physical interpretation of the ODF coefficients W400 and W420 is given. The W420 coefficient depicts the effect of birefringence of shear bulk elastic waves, the W400 ratio is linearly related to Poisson's ratio. Both coefficients are structurally sensitive characteristics and are used to assess the state of materials by non-destructive testing methods. As a results of the study, it was found that the characteristic areas on the tension diagram: the yield area, the area corresponding to parabolic hardening, the beginning of neck formation, have a corresponding display on the dynamics of changes in the coefficients of the orientation distribution function.

The yield area is characterized by an active change in the characteristics of the texture. Hardening leads to a decrease in the intensity of change in the coefficients of the orientation distribution function. Expressions are given that relate changes in Poisson's ratio to the value of hardening of the steel under study, the parameter of acoustic anisotropy with the value of plastic deformation. The calculated values of the hardening value according to the data of acoustic measurements are in good agreement with the hardening value obtained by analyzing the tensile diagram. The error in determining the magnitude of plastic deformation by the acoustic method was no more than 0.3%. It was found that monitoring the elastic characteristics by the acoustic method makes it possible to effectively assess the state of plastically deformed steel by a non-destructive testing method.

The behavior of samples of the promising pipe steel X100 under dynamic three-point bending is studied. This steel is compared with steel X80 currently used in the gas transmission pipeline engineering.

Experimental and calculated mechanical characteristics were obtained for pipe steel X100 produced by JSC “VMZ” using data of the standard tests for laboratory samples and drop-weight tests (DWT). Steel X100 demonstrates higher strength indexes in comparison with steel X80, however, it has lower indexes of plasticity and ductile fracture resistance.

High-speed video-recording of the crack propagation in a sample of steel X100 was performed in the drop-weight test. In combination with the sample resistance force dependence on the drop-weight movement distance, such testing provided much more information for studying the metal resistance to ductile fracture and allowed revealing the crack propagation law, estimating the specific dissipation energy during the crack propagation, and verifying the computational model used in DWT.

Parameters of the X100 steel strain and fracture model were calibrated. The numerical simulation of the behavior of the X100 steel samples in tests at room temperature was performed. Simulation results satisfactorily agree with data of the tests with regard to such parameters as: the sample resistance force dependence as a function of the drop-weight movement distance; the striker work; strained foils, and macrogeometry of fractures in the tested sample.

This results may be used for the development of requirements and conditions of using equipped DWT, as well as for the numerical simulation of full-scale tests of pipes made of steel X100 to predict the pipeline resistance to a propagating ductile crack.

The methodological and analytical part of the article analyses the valuation of residential real estate in global assets, where its share reaches more than 45%. The place of residential real estate in the wealth of households, where its share exceeds 50%, is considered. On this basis, it is proved that the largest residential segment is formed in the economy, which begins with the creation of residential real estate and is extended by the need for their further maintenance, repair and operation with significant funds from homeowners. Given the social function of housing and the impossibility of self-sufficiency of a significant part of households in any country, the need for the formation and consideration of two subsystems of housing ownership: individual and socialized in various forms.

Based on the hypertrophied privatization of private housing in Ukraine, the inability of its inefficient owners to preserve and maintain it has been shown. The rational ratio between the cost of residential real estate, the volume of new construction and capital investment in repairs is demonstrated.

The conclusion is made about the need and ways to transform the housing sector in Ukraine in the direction of a rational relationship between these subsystems and to ensure their viability.

In Ukraine, the construction costs in the investor's estimates is calculated by the resource method - using resource element estimation norms. Therefore, the accuracy in determining the components of these norms can cause the error in calculating the construction costs of the object. In this article, the example of construction materials shows the influence of the resource name in the resource element estimation norm on the accuracy of determining the market price of this resource in the estimating documentation, and thus on the accuracy of the construction costs calculation at the stage of the investor‘s costs planning. The main attention is paid to search for the ways to reduce the quantity of the samples, as the main factor influencing the critical indicators - the time and cost of work to determine the market price of the construction materials. The unification of the construction resources names in the resource element estimation norms and a problem of comparison of these names with the real building materials is highlighted in the article too. The examples show which elements in the name of construction materials in the element resource norm contribute to the reduction of the samples quantity and affect the price variation for the samples and the general set of market prices of the relevant materials. This article offers the term "name of the resource  for estimation" which generalizes and characterizes the names of materials in DSTU (national standard of Ukraine) and SOU (standards of organization of Ukraine) resource element estimation norms. The rules of formation, use and specification of the "name of the resource for estimation" during the development of resource element norms and at all stages of design and construction of the object are offered too. The author proposes the amendments to the current procedure for the development and revision of resource element estimation norms, which will help to reduce the errors in determining the market price of construction resources during the creation of estimation documentation.

A study of the economic stability of construction companies at the sectoral level identified trends in changes in the structure of construction as a macroeconomic sector, the volume of income from construction activities, assets and liabilities of enterprises of various sizes. In order to study the changes in the level of sectoral competition, the dynamics of the structure of the distribution of construction enterprises by size was studied. For the final conclusion on the monopolization of the industry, in addition to the quantitative structure of enterprises, it is necessary to analyze the distribution of their income depending on the size. Therefore, accordingly, such a distribution is given not only depending on income, but also taking into account the number of employees. The average growth rate of the number of entities, their income and the number of employees according to the size of enterprises were calculated.

Trends in the development of construction companies are studied, their features, typical risks and threats, which are the low level of anti-crisis potential, which is manifested in the reduction of the number of construction companies and the number of employees. It is determined that during the analyzed period there was a steady decrease in the financial stability of enterprises of all sizes. At the same time, the role of small enterprises in the development of the construction sector grew, as, firstly, macroeconomic conditions negatively affected the performance of large enterprises, secondly, changes in the Government structural policy priorities, reforms in the direction of decentralization in general contributed to the activation of small business and private entrepreneurship. Small construction companies increase their revenues, assets, and income much more each year than large and medium-sized ones. It is due to the growth of income indicators and balance sheet items of small enterprises that the whole construction industry is growing, as the representatives of small construction business have the largest share in the trend.

The identified patterns proved the need to develop methodological approaches to increase anti-crisis potential and increase viability in a competitive environment not only for small construction companies, but also for medium and large ones.
Мethodical approaches to human resources management in innovative enterprises
Authors: Leszczynski V.P
Published: November 2021

The article substantiates the theoretical and methodological provisions and practical recommendations for the human resources management system in innovative enterprises. The peculiarities of an innovative enterprise are determined, the main methods of evaluation and recruitment are researched and classified, taking into account modern requirements for creativity and innovation. It is substantiated that economic transformations have significantly changed the status of the organization as the main link in the production of material goods or the provision of various services. The market puts the organization in a new relationship with government agencies, with production and other business partners, directly with employees. New economic and legal regulators are being established, relations between the manager and subordinates are changing, between employees within the organization. Due to this, the requirements for human resource management are growing, where the human factor becomes the main factor of production. Human resource management includes all aspects related to the workforce: management, employers, workers, students, professionals. As labor markets have become more competitive, human resources professionals are now designed to provide people management techniques that not only support the institution's priorities but also ensure success in the global market. Institutions also strive to create an employment brand that resonates with specific employees. Institutions of all sizes and all industries are increasingly recognizing the importance of people. Managers and economists have traditionally seen human resource management as a mandatory expense rather than a source of value for their organizations. Economic value is usually associated with capital - equipment, technology and technical means. The limit for business expansion is not only the availability of financial capital, but also access to talent - human capital. Thus, people are crucial to organizational success, and the human and intellectual capital of the organization's staff provides an opportunity for significant competitive advantage. The content of the concept of "profitability of talents" is substantiated, the components of strategic management of human resources of the enterprise are investigated. The key characteristics and features of human resources management as a factor in supporting the growth of innovative development of the enterprise are summarized.
Investment risk management and energy efficiency, considering capital and operating expenditure in industrial development

The article clarified the impact of investment risk management on energy efficiency as a significant factor affecting the cost of an industrial development project. The effective implementation of any new construction or reconstruction project is inextricably linked with financial risk management, that allows take into account all possible expenditures that are not only once spent on its implementation (capital expenditures), but also operational expenditures that will be incurred when it is transferred into operation. A very important problem is the assessment of the real cost of the project, taking into account the operational expenditures during the life cycle of the building, as well as the optimization of both the capital expenditures (CAPEX) of the development company and the operational expenditures (OPEX). The implementation of development projects can be divided into three main stages: pre-investment, investment and operational. The sources of possible successes or failures in the implementation of entrepreneurial development projects are questions that are usually laid down in the early stages of organizing the construction of real estate objects. Therefore, the most important feature in the construction projects management in the field of industrial development is taking into account the dominant influence exerted on the efficiency of the first, pre-investment, phase. As a result, it allows to obtain significant cost-savings in the total cost of the project. All this requires to analyze various design solutions due to the Investor's desire to optimize capital expenditures, which will significantly reduce the costs of some project design solutions. Considering the above, a calculation algorithm is proposed to determine the total cost of the building's life cycle. During the research, an economically and energy-efficient model of using the enclosing structure for an industrial building was determined, which allows obtaining significant costs-savings, taking into account the operational expenditures during the life cycle of the building.
Cost structuring in order to reduce expenses of enterprises

Published: November 2021

The efficiency of current costs of production resources is the basis of enterprise profitability and competitiveness. This requires annual planning and implementation of specific innovative measures to ensure economical and rational use of all production resources for all structural items and cost elements. The current costs of production resources include costs for: features of technology, organization of construction production, control of production processes, quality assurance of construction work (СW), construction management, sales of construction products. By the nature of participation in the production process, the current costs of production resources are grouped into direct and indirect costs. Of particular note are the costs of basic materials, which by share are the largest among direct (immediate) current production costs, as well as the efficient use of energy resources. In addition, author provides analysis of all components of direct costs, including the cost of basic and auxiliary materials, energy resources, wage costs, operation of machinery and equipment. Innovations and measures of economical and rational consumption of basic materials and energy resources in construction are formed in the following list: material resources - search for rhythmic suppliers, optimization of stocks, ensuring regulatory minimum tolerances, use of serviceable equipment and devices, strict control and self-control of costs, high quality for the first time, training with workers, visual check of sizes and tolerances, strict accounting and compensation for losses. Similarly, the structuring of the two main parts of indirect costs, i.e. general production and administrative, is performed. Such a detailed costs structuring allows for greater specification in the planning and implementation of innovative measures to reduce expenses and increase the level of firm profitability and competitiveness.
