The aim of the work is to develop scientific and methodological approaches to modelling the optimal strategy to increase the competitiveness of pharmacy chains (PC), which belong to different clusters.
Materials and methods. The algorithm for determining the optimal strategy for increasing the competitiveness of PC for different clusters using the method of constructing a decision tree and cluster analysis is proposed. To solve this problem, an expert survey of more than 400 pharmacy managers, who were part of the PC of different sizes, was previously conducted. According to the results of an expert survey using hierarchical clustering methods based on the values of 13 input variables - scores of the strengths of the competitiveness of the PC, three clusters of networks were identified, each of which proposed its own algorithm for modelling the optimal strategy of competitiveness.
Results. Using modern economic and mathematical tools, the distribution of PC depending on their size into clusters for modelling the dynamics of competitiveness is substantiated. Indicators are identified, which show a significant difference between clusters, which was taken into account in the process of modelling and selection of the optimal strategy to increase the competitiveness of PC. It is established that the biggest negative impact on the strategy of increasing the competitiveness of small networks has a slow response to changes in market conditions, the biggest positive impact – the availability of additional services in the networks; for medium PC the most important factors influencing the level of competitiveness are the location of pharmacies and competent management; for large PC – the use of modern automated management programs, the level of efficiency of the marketing complex and location features.
The algorithm of the generalized model of “decision tree” for a choice of optimum strategy of increase of competitiveness depending on the size of PC is constructed. It was found that the following factors are of the greatest importance: the size of the PC, the use of the discount card system, and the least - the speed of response to market changes and the stability of the financial condition.
Conclusions. The proposed generalized mathematical model of the “decision tree” allows a reasonable approach to choosing the optimal strategy to increase the competitiveness of PC depending on its size. The assessment of the importance of predictor variables for each cluster of PC allows determining the priority factors in the implementation of measures aimed at implementing the chosen strategy to increase competitiveness
Water disinfection under the helium influence
Authors: Koval Iryna 
Published: September 2021

The object of research is the process of water disinfection at the influence of gas from bacteria of a particular genus with different amounts per unit volume of water. Due to the annual increase in the amount of pollutants in natural waters, new opportunities to improve microbiological indicators of water quality are being explored. There are many different ways to disinfect it, both physical and chemical. However, no single method has been found to purify aqueous media from microorganisms that would ensure their effective destruction. It is proposed to study the activity of specific microorganisms during the bubbling of inert gas through the aqueous medium. The microorganisms studied were rod-shaped sporogenic cells of Bacillus cereus bacteria type. The test gas was inert helium. The study used continuous gas bubbling throughout the process, which allowed to mix microbial water efficiently and prevent the formation of stagnant zones in the reaction medium. In particular, active gas mixing facilitates its access to each cell. The gas supply rate corresponded to 0.2 cm3/s, and its flow rate was 0.7 dm3 for one hour of bubbling through microbial water. The duration of the entire research process was 7200 s. The constant temperature of the microbial water (T=288±1 K) was maintained during the experiment by cooling the glass reactor with running water. An in-depth method of culturing bacterial cells was used. A decrease in the number of microorganisms was observed throughout the helium supply process, despite the different initial amounts in the water. The highest destruction degree of bacillus (77.06 %) was obtained at the lowest studied concentration in water (NM01=3.4·104 CFU/cm3). This is due to the fact that less microbial load provides better conditions for access of helium to the cell and their effective destruction. The proposed method of water purification allowed to achieve a sufficiently high degree of water disinfection from sporogenic rod-shaped bacteria after the action of helium alone. In particular, it has been experimentally proven that the efficiency of the water disinfection process depends on the concentration of microorganisms per unit volume of water. Due to the treatment of contaminated water with gas, it is possible to obtain high rates of its purification and the application of this method for practical purposes in water treatment technology.

Published: September 2021

The object of research is a sour cream product with the addition of phytosterols in terms of the finished product from 0.141 to 1.710 g/100 g of product. One of the most problematic places when using phytosterols is their extremely low solubility in water and fats. There are several ways to add phytosterols to foods. Direct application is represented by suspensions of phytosterol nanoparticles. To improve the solubility in water, phytosterols are converted into the form of glycosides. To improve the solubility in fats and oils, phytosterols are converted into fatty acid ethers. An important issue in the development of fermented milk products is the effect of phytosterols on the homogeneity of the system, the fermentation process, the final properties of the product. During the study, the introduction of pre-esterified phytosterols as a substitute for milk fat with a melting point of 32–34 °C to milk-fat mixtures. Milk-fat mixtures of various compositions were fermented with the study of acidity during fermentation. To study the properties of the system, milk fat was replaced by vegetable fat by 25, 50, and 75 %. The content of lactic acid bacteria was determined for the final product and the organoleptic parameters of the product were compared. The results show that when fermenting for 14 hours, the required acidity parameters of pH 4.2 to 4.6, titratable acidity of 76 to 79 °T were achieved at 12 hours. Phytosterols did not harm the fermentation rate, and after the process did not worsen the taste and appearance of the product. This provides the opportunity to obtain a high-quality sour cream product with additional properties. The process of fermentation of sour cream products with phytosterols corresponds to the parameters of the standard sour cream product and sour cream. This provides advantages such as the ability to integrate a new product into the sour cream and sour cream production system without significant changes in technology and equipment.

The object of research is the process of concentrating fruit and vegetable purees in an improved rotary film evaporator. The existing hardware design of traditional processes for processing fruits and vegetables, as a rule, is not unified enough, inconvenient in operation and is designed for high productivity. Concentration of fruit and vegetable purees occurs mainly in vacuum evaporators of periodic and continuous operation at a temperature of 60–80 °C under vacuum, which allows them to significantly preserve their nutritional value. But the duration of the process remains very significant (in devices of periodic action up to 75–90 minutes). One of the most problematic areas in the concentration of fruit and vegetable raw materials is significant losses of biologically active substances. At the same time, an important indicator of the quality of the process of concentrating pasty fruit and vegetable pastes is the value of the heat transfer coefficient, which characterizes the efficiency of the heat transfer method and the design features of the mixing device, taking into account the thermophysical characteristics of the product. To create conditions for conducting research to determine the heat transfer coefficient, it is necessary to use instrumentation with precise regulation of the necessary technological parameters.
To study the heat transfer coefficient when concentrating fruit and vegetable purees, an automatic installation of an improved rotary evaporator was designed. The improvement of the rotary film evaporator (RFE) is carried out due to the lower location of the separating space by installing a screw discharge of the paste and preheating the output puree with secondary steam.
The experimental dependences of the heat transfer coefficient on the product flow rate make it possible to determine the rational values of the flow rate of the RFE feedstock at various values of the rotor shaft speed. It is found that the heat transfer coefficient is influenced to a large extent by the product consumption, and the rotor speed acts to a lesser extent, only the relative speed of fluid passage around the developed hinged blade changes. It is found that when the frequency changes from 0.3 to 1.7 s–1, an increase in the heat transfer coefficient by 1.45 times is observed, which is explained by a more intensive degree of mixing of the product by the blades.

Authors: Trofymenko Olena 
Published: September 2021

The object of research is the processes of formation and implementation of mechanisms for innovative development of the energy sector of the national economy in the context of the fourth industrial revolution. It was determined that at the global level, mechanisms for innovative development of industry and energy are formed in the New Industrial Strategy of the European Union (EU), the Paris Climate Agreement, and the fourth energy package of the EU. The challenges of Industry 4.0 necessitate the formation and adaptation of these mechanisms in individual countries to ensure the innovative development of the energy sector in different countries.
In the course of the study, the scientific and applied foundations of ensuring the development of the energy sector at the state level have been analyzed. They also used a system-functional approach, methods of structural and functional analysis and functional synthesis, critical analysis of regulatory framework, goals and objectives in the energy sector of the national economy. As a result, a comprehensive mechanism for the implementation of the national innovation policy in the energy sector of the national economy at various levels of the social hierarchy has been proposed. In particular, 5 functional components of the innovative development of the energy sector of the national economy have been identified:
1) productivity of innovation;
2) effectiveness of innovation policy;
3) effectiveness of energy innovation;
4) investment support for innovative development of the energy sector;
5) development of human capital in terms of decarbonization of the economy.
On the basis of these components, the main mechanisms have been formed, which make up a comprehensive mechanism for implementing the state policy of innovative development of the energy sector of the national economy, and each of these mechanisms has its own set of implementation tools: economic; motivational; organizational-technological and political-legal. This forms the basis for the implementation of its interfunctionality and ensures its functioning, based on the principle of multilevel (elements relate to the supranational, interstate, national, regional, local and sectoral levels) and is intended to enhance the socio-economic effects of Industry 4.0.

Authors: Umanskii A. A. , Yur'ev A. B. , Dorofeev V. V. , Dumova L. V. 
Published: September 2021

Based on the studies of stress­strain metal formation during railway rails rolling in roughing stands of a universal rail­and­beam mill, carried out using the DEFORM­3D software package, the authors have determined the features of distribution of the Cockcroft­Latham criterion over the cross­section of the rolled stock of various shapes. An extremely uneven distribution of the Cockcroft­Latham criterion over the roll section has been established. According to the data obtained, values of the specifed criterion are minimal in the axial zone, and in the near­surface layers the greatest value of the Cockcroft­Latham criterion and, accordingly, the highest probability of defects formation occur near the gauge vertical axis. In gauges of complex shape (“trapezium”, “recumbent trapezium”, rail gauges), the authors have revealed the presence of local zones with maximum Cockcroft­Latham criterion, located in the places where the foot of the rail profle is formed. And rolling in gauge of the “trapezium” type is marked by the presence of such a zone in the near­surface area near the gauge vertical axis. Within the framework of determining formation regularities of the diagram of metal stress­strain state at the initial stage of rail rolling, direct relationship was established between the uneven temperature distribution over the section of rolling and the values (maximum and average over the section) of the Cockcroft­Latham criterion. At the same time, it was shown that uneven temperature distribution over the cross­section of the roll tends to decrease with an increase in the coefcients of extracts along the passes and increase in tilting frequency, regardless of the shape of the used gauges. For gauges of complex shape, in addition to the listed parameters, an increase in similarity of shape of the roll and gauge used also has a signifcant eﬀect on reducing temperature inhomogeneity. Based on the results of theoretical studies, a new mode of railway rails rolling has been developed. Its pilot testing in the conditions of a universal rail­and­beam mill of JSC “EVRAZ ZSMK” has shown a decrease in rail rejection by 0.78 % compared to the previously used rolling mode.
Old English Power Structure in the Warlike Nature in Riddles no. 3, no, 29, no. 50 from the Exeter Book
Authors: Widodo Herditya Wahyu 
Published: September 2021

Abstract: This study focuses on Old English nature-themed riddle texts from the Exeter Book, analyzing the natural imageries that are significant in investigating how the literary content of Old English riddles, as accepted forms of poetry, reveals the Anglo-Saxon culture of their original authors. I focus on the power structure in Anglo-Saxon society revealed in the riddles, by analyzing the topic of warlike nature in them, focusing on the riddles no. 3, “Storm”, no. 29 “Sun and Moon,” and no. 50, “Fire.” Natural experience described in these riddles is rendered by the Anglo-Saxons to reflect power hierarchy between male and female, servant and master, and human with God. The Anglo-Saxon riddles identify and assign the potent warlike attributes and actions of nature, and assign them to the more powerful factions (God, Master, Male) over the weaker factions (Humans, Servants, Female). This is done by the authors as an acceptable cultural interpretation of these natural phenomena, put in the riddles to make it possible for the riddles’ intended Anglo-Saxon audience as clues to arrive at a culturally agreeable answer.

Abstrak: Studi ini berfokus pada teks teka-teki (Riddles) Inggris Kuno (Old English) bertema alam dari the Exeter Book, dengan menganalisa imaji alam yang signifikan, untuk mengetahui bagaimana teka-teki Inggris Kuno, sebagai salah satu karya sastra berbentuk puisi, mengungkapkan budaya Anglo-Saxon dari penulis aslinya. Saya berfokus pada struktur kekuasaan (power structure) dalam masyarakat Anglo-Saxon yang terungkap dalam teks teka-teki, dengan menganalisis topik sifat suka perang di pada teka-teki no. 3, "Badai", no. 29 “Matahari dan Bulan,” dan no. 50, "Api." Pengalaman hidup mengenai alam digambarkan dalam teka-teki ini oleh para penulis Anglo-Saxon dengan mencerminkan hierarki kekuasaan antara laki-laki dan perempuan, hamba dan tuan, dan manusia dengan Tuhan. Teka-teki Anglo-Saxon mengidentifikasi dan menetapkan atribut dan tindakan alam yang suka berperang (warlike) kepada faksi yang lebih kuat (Dewa, Tuan, Laki-Laki) di atas faksi yang lebih lemah (Manusia, Pelayan, Wanita). Hal ini dilakukan oleh para penulis sebagai interpretasi budaya atas fenomena alam yang mereka lihat, dan dimasukkan ke dalam teka-teki untuk memungkinkan pembaca Anglo-Saxon sebagai petunjuk untuk sampai pada jawaban yang dapat diterima secara budaya.
