On a 1D-electrostatic test problem for the PIC method
Authors: Chizhonkov Eugene V.
Published: February 2024

A test problem for the ‘particle-in-cell’ method is proposed which allows one to check individual errors on each stage of numerical implementation of the method. General testing usually controls only total (final) error. Using the test problem, we analyze errors of a difference method of MacCormack type and the CIC method being the most popular version of the ‘particle-in-cell’ method. It is shown that the CIC method having also the second formal order of accuracy is seriously inferior to the difference method under the same given error and same grid parameters. In particular, the results of the particle method lose their sense after approximately one calculation period, although the time interval of confidence in simulation data for the difference method is practically unlimited. The testing method proposed here is suitable for an arbitrary one-dimensional version of the ‘particle-in-cell’ method, and it allows one not only to compare numerical implementations of individual stages with each other, but also to verify available theoretical results.

Published: February 2024

Advanced numerical climate models are known to exhibit biases in simulating some features of El Niño–Southern Oscillation (ENSO), which is a key mode of interannual climate variability. In this study we analyze how two fundamental features of observed ENSO – asymmetry between hot and cold states and phase-locking to the annual cycle – are reflected in two different versions of the INMCM Earth system model (state-of-the-art Earth system model participating in the Coupled Model Intercomparison Project). We identify the above ENSO features using the conventional empirical orthogonal functions (EOF) analysis, which is applied to both observed and simulated upper ocean heat content (OHC) data in the tropical Pacific. We obtain that the observed tropical Pacific OHC variability is described well by two leading EOF-modes, which roughly reflect the fundamental recharge-discharge mechanism of ENSO. These modes exhibit strong seasonal cycles associated with ENSO phase locking while the revealed nonlinear dependencies between amplitudes of these cycles reflect ENSO asymmetry.We also assess and compare the predictability of observed and simulated ENSO based on linear inverse modelling. We find that the improved INMCM6 model has significant benefits in simulating described features of observed ENSO as compared with the previous INMCM5 model. The improvements of the INMCM6 model providing such benefits are discussed. We argue that proper cloud parameterization scheme is crucial for accurate simulation of ENSO dynamics with numerical climate models.

Company-Specific Plant Roles
Authors: Kaiser Jens , Friedli Thomas
Published: February 2024

The interaction between a firm’s headquarters and its plants is crucial to ensuring that the manufacturing network generates a competitive advantage. The concept of plant roles, first introduced by Ferdows (1989), is a suitable tool to facilitate the headquarters-plant relationship. Although many articles deal with Ferdows’s plant roles, hardly any can be found that discusses how companies can design and deploy their own plant roles. Thus, this article proposes a step-by-step guide for network managers.

Authors: KACZMAREK DOMINIKA , WÓJCIK MALWINA , KAPUŚNIAK KAMILA , KAPUŚNIAK JANUSZ
Published: February 2024

Background. Vegetable and fruit mousses have become very popular among consumers. These products are a source of complete nutrients, providing the body with vitamins, minerals and dietary fiber. However, the overall fiber content in a single serving of mousse has turned out to be insufficient. The aim of the study was to examine the functional properties of vegetable and fruit mousses before and after enriching them with a fiber preparation from potato starch (SDexF). The research material consisted of three mousse flavors: apple-peach-parsnip, apple-cherry-carrot and apple-carrot-quince. The research included pH measurement, analysis of CIE L*a*b* color parameters and pasting characteristics of vegetable and fruit mousses. The content of total dietary fiber (TDF) in vegetable and fruit mousses was also determined using the enzymatic-gravimetric AOAC 991.43. method. Results and conclusion. The addition of SDexF resulted in a slight decrease in the pH of the applecherry-carrot mousse. For each flavor, a change in color was observed, with the largest difference in color parameters (ΔE) observed in the apple-carrot-quince flavored mousse. The vegetable and fruit mousses enriched with SDexF were characterized by a higher total fiber content compared to the unenriched mousses. The preserves with the addition of SDexF were characterized by lower pasting parameters compared to the control mousses. Based on the functional tests being carried out, no negative impact of the enriching of vegetable and fruit mousses with SDexF on the final product was observed. It can therefore be concluded that the use of SDexF affects the functional properties of vegetable and fruit mousses, increasing their nutritional and health value.

Authors:   Kharkiv State Academy of Physical Culture, Volodchenko А.
Published: February 2024

Purpose: to develop model characteristics of the modern competitive activity of the world's best athletes in Greco-Roman wrestling. Material and methods. The research used the following methods: analysis of scientific and methodological information and Internet sources; analysis of protocols and video recordings of competitive activities; expert assessment, methods of mathematical statistics. An analysis of 51 matches at the 2023 World Cup and Continental Championships (Europe, Asia, Pan America) was carried out. The object of observation were the wrestlers who took the first places at the 2023 World Championship in the Olympic weight categories (60 kg, 67 kg, 77 kg, 87 kg, 97 kg, 130 kg). Results: the analysis of scientific and methodological information and Internet resources allowed to determine that the analysis of competitive activity in sports wrestling is important for predicting the success of athletes and building models of the world's strongest wrestlers. The 2023 world champions in the Olympic weight categories also took first place this year and at continental competitions (Europe, Asia, Pan-America), except for the wrestler in the 87 kg weight category - he took second place at the 2023 European Championship. Based on the analysis of protocols and competitive activity, model characteristics of the modern competitive activity of the world's best wrestlers in Olympic weight categories were compiled. The analysis of the model characteristics of the competitive activity of the world's strongest wrestlers of different weight categories showed that each athlete uses basically the same technical and tactical actions during the day, but the tactical algorithm of fighting and conducting techniques is individual for each wrestler. Conclusions. The analysis of fights at the 2023 World Championship in Greco-Roman wrestling made it possible to develop model characteristics of the competitive activity of the best wrestlers in Olympic weight categories. It has been established that the strongest fighters use from 3 to 7 technical and tactical actions to achieve victory in a fight. The most performed tricks on the floor are rollovers and throws with the back belt, and in the rack - fallbacks and push-ups behind the carpet. The evaluation of the structure of the technical arsenal showed the superiority of the parameters of the champion in terms of the number of successful attacks and points won, along with low values of missed attacks and lost technical points. The developed model characteristics of competitive activity of the best wrestlers allow the coach to more effectively organize and manage the training process, timely identify deficiencies in the wrestler's preparation and make certain corrections. Keywords: modeling, competitive activity, indicators, technical and tactical actions, Greco-Roman wrestling, elite athletes.

Published: February 2024

Purpose: to theoretically substantiate and experimentally identify the most effective means of modern high-intensity interval fitness training of pre-competitive training of qualified athletes in WTF taekwondo. Material and methods. The following methods were used in the research: the analysis of the special scientific and methodical literature; pedagogical observations; pedagogical experiment; pedagogical testing; physiological testing; the method of expert estimations; methods of mathematical statistics. Results: the explosive growth of lactate concentration from 1,16±0,5 mM/l to 15,5±2,1 mM/l causes the next repetition of this exercise after 5 minutes of rest. The obtained data of HR (HR, bpm +26,2 %), VE, l/min (+128,6 %), VCO2, l/min (+135,5 %), VO2, l/min (+56,1 %), KIO2 (-27,5 %) indicate that at insufficient recovery between approaches at performance of rather short interval segments of submaximal power (high-intensity work up to 1 min) leads to the significant decrease of special working capacity of sportsmen. Taking into account the specifics of the sport, for the improvement of this parameter of preparedness it is considered expedient to perform 3-5 times specially developed blocks of exercises of high intensity, borrowed (mainly) from modern methods of health-improving fitness training. The results of the competitive activity of qualified taekwondo athletes confirmed the effectiveness of the use of high-intensity fitness training HIIT to improve their pre-competitive fitness. Conclusions. When planning the direct pre-competitive training of qualified taekwondo sportsmen in the annual cycle of preparation it is necessary to be guided by the information received as a result of the conducted researches and to approach in a regulated way to the definition and combination of intensity and duration of the performed exercises of a specific orientation which, in turn, model the process of competition. It is proved that to improve aerobic endurance of athletes it is necessary to plan 2-3 times in a weekly microcycle different interval training exercises performed without significant fatigue and decreased performance. For improvement of high-speed and power capabilities of sportsmen it is necessary to perform 1-2 times during a microcycle different interval training exercises with shortened segments of work of maximum intensity lasting up to 30 s. Keywords: fitness training, high-intensity interval training (HIIT), taekwondo, WTF, physical fitness, control, speed and strength capabilities, aerobic capabilities.

Authors:   German Sport University Cologne, Korobeynikov G. , Kokhanevich A. ,   National University of Physical Education and Sport
Published: February 2024

Purpose: research of psychical state in qualified wrestlers in stage of special basic fitness. Material and methods. The study involved 31 skilled Greco-Roman wrestlers aged 14-16 years, pupils of the wrestling club in Kremenchuk. To assess the mental state of skilled wrestlers, the Luscher color test was used. According to the results of the study, the following indicators were obtained: performance, fatigue, anxiety, deviation from the autogenous norm, eccentricity, concentricity, vegetative coefficient, heteronomy and autonomy. Heart rate variability was studied as an indicator of mental stress. The cardiac monitor «Fazagraf» was used. Based on the results of the study, we obtained statistical processing indicators and spectral characteristics of cardiac intervals. Non-parametric statistics with the determination of the median, lower and upper quartiles were used to assess the differences between the studied parameters. Results: in wrestlers with high tension of the autonomic regulation system, a deterministic functional system aimed at ensuring the mental state is revealed. At the same time, an increase in the tension of autonomic regulation is accompanied by mental fatigue, anxiety, passivity and the presence of mental stress. Prevention of mental stress in skilled wrestlers may be associated with the activation of the athlete to external environmental stimuli, optimism and a mood for positive behavior. The relationship between the indicators of mental state and the parameters of mental functions in skilled wrestlers was revealed. The moderate tension of the heart rate regulation system in skilled wrestlers is accompanied by an increase in mental performance and a decrease in anxiety. In turn, the increase in the tension of autonomous regulation is reflected in the presence of internal psychological discomfort and independence in the formation of decision-making. However, there is an increase in anxiety and a decrease in mental performance. Conclusions. The relationship between indicators of mental state and parameters of psychical functions in qualified wrestlers was revealed. Moderate tension of the heart rhythm regulation system in qualified wrestlers is accompanied by an increase in mental capacity and a decrease in anxiety. The increase in the tension of autonomous regulation in qualified wrestlers is reflected in the presence of internal psychological discomfort and independence in decision-making. Keywords: mental state, qualified wrestlers, heart rate regulation, indicators, analysis.
Comparison of the Spreading History of Two Introduced Cepaea Species (Gastropoda, Helicidae) in Ukraine with Remarks on Their Phenotypic Variability
Authors: Gural-Sverlova N. V. , Rodych T. , Gural R.
Published: February 2024

Trends of the current dispersal of Cepaea nemoralis and C. hortensis in Ukraine are analysed, which are closely related to the activities of several garden centres, which export a part of the sold seedlings of ornamental and garden plants from other European countries. Using Lviv and its environs as an example, we compared the qualitative and quantitative phenotypic composition of C. nemoralis at sites where both Cepaea species or only C. nemoralis were recently introduced. On average, the former were characterised by a greater phenotypic diversity of C. nemoralis, which may be due to a greater number of founding individuals of such colonies. At the sites of the second group, hereditary traits (brown ground colour, shell with three lower bands) or phenotypes (yellow unbanded), which are less common in the study area, were more often absent. Also, a clearly pronounced predominance of any one variant of the shell colouration was more often noted there, most often pink unbanded or yellow mid-banded.
The Breeding Population of the Rook, Corvus frugilegus (Aves, Corvidae) in Kharkiv, Ukraine: Nearly 22-times Decline in Numbers Over an 80-year Period
Authors: Brezghunova O. O. , Sinna O. I.
Published: February 2024

Based on regular surveys of the distribution of rookeries and the number of nesting birds of Corvus frugilegus Linnaeus, 1758 carried out in 2002–2020 using the TRIM (TRends & Indices for Monitoring data), the trajectory of change in the rook population has been estimated. The total size of the breeding population of rooks in Kharkiv City has decreased by 95.4 % over the last 80 years, from 940 to 43 breeding pairs. The general trend for 1939–2020 is a moderate decline (multiplicative slope 0.980, standard error 0.004; p < 0.01). A similar trend was observed for 2002–2020 when surveys were regular, i. e. a moderate decline (multiplicative slope 0.920, standard error 0.021; p < 0.01). Rooks still use the centre of the city for nesting, as they did in the early 1940s, but from the 1980s they began to breed in the eastern part of Kharkiv, where most of the population is now concentrated. Rooks breed in two clustered colonies, one in the central and one in the eastern part of Kharkiv City, about 13 km apart. The colonies are not numerous (all less than 50 pairs) in the last 10 years. The possible causes of the decline of the rook population in Kharkiv City are discussed.

As a result, the classification of regions with regard to infrastructure development is proposed. In addition, an equilibrium equation in the tourism market concerning infrastructure facilities is suggested, which can be used to assess the balanced development of general infrastructure. The findings underscore the need for policymakers and stakeholders to recognize the direct correlation between infrastructure and tourism success, providing insights to guide future infrastructure planning and development initiatives in the ever-evolving global tourism landscape.
The value premium in the Vietnamese equity market
Authors: Quy Duong Le
Published: February 2024

In recent decades, the Efficient Market Hypothesis has been the subject of debate among professionals and academics. In this hypothesis, the value premium is a key aspect that challenges market efficiency. The main objective of this study is to comprehensively investigate the value versus growth anomaly in the Vietnamese market between 2013 and 2023. Based on the empirical data, value portfolios have yielded a greater average return than growth portfolios in the Vietnamese stock market during this period. Although their levels of market risk (measured by beta) are nearly the same, the added-risk level of value portfolios is substantially higher than growth portfolios. Therefore, the value premium in Vietnam is compensated for bearing a higher risk level, consistent with the risk-based explanation.
AUTHENTIC WHEAT GRAIN IS THE RAW MATERIAL FOR MODERN CEREAL PRODUCTS
Authors: Sots S. , Kustov І. , Donii О.
Published: February 2024

Wheat grain is one of the eight traditional crops that needs to be reviewed in terms of its processing, product range, and quality properties of the end products. Considering the Rules of management and organization at grain factories, it can be noted that the recommended raw material for the production of grain products is durum wheat, the processing of which allows obtaining the main assortment of wheat:groats "Poltavski" and "Artek". Today, durum wheat in our country are grown in a small amount compared to soft wheat, which is widely used in flour milling, therefore enterprises of the cereal industry in such conditions must either import significant volumes of durum wheat or use soft wheat as an alternative option, but taking into account the peculiarities of the produced groats and the technological process, which is built for a stronger grain, the processing of soft wheat in such conditions and the production of crushed groats "Poltavski" and "Artek" from it cannot be considered effective. A key factor in the efficiency of soft wheat processing in groats production is also the difference in the chemical composition of two types of wheat, in which soft wheat has, for example, a lower mass fraction of protein compared to durum wheat, which does not allow production from soft wheat modern products of healthy and complete nutrition, the demand for which is only growing every year in the World and Ukraine. Emmer is one of the oldest cereal crops that mankind used for food and fodder needs. Cultivation of emmer began approximately 10,000-8,000 BC on the territories of ancient Egypt, Mesopotamia, Syria, Ethiopia, as well as other countries of Asia, North Africa and the Middle East. On the territory of Ukraine, emmer was grown 5-6 thousand years BC. When processing emmer into groats, the total yield of end whole groats can be obtained at the level of traditional cereals from hulled cultures - up to 70%, and flakes in relation to unprocessed grain 60-65%. That is, it will not be possible to significantly increase the yield of finished products during the processing of emmer, and this is primarily explained by the filminess of this culture, but if compare the quality of the obtained products, the advantage is clearly for products from emmer, which is already a proven fact, for example in the countries of the European Union where the demand for products made from "original" hulled wheat, including emmer, is increasing every year. Our country has all the necessary conditions for the development of this culture and increasing the volume of its cultivation and processing into food products, which in turn can increase the export potential of our country not only in the form of raw materials, but also products from it.

Published: February 2024

This study describes the synthesis of a new bioadsorbent from chitosan using ethylenediaminetetraacetic dianhydride (EDTAD) as a modifying agent and its successful application for removal of a cationic ion (copper (II) (Cu2+)) and oxyanions of chromium (VI) (Cr6+) from single-component aqueous systems. The new multifunctionalised chitosan derivative (C1) was produced through chemical modification of the primary hydroxyl function of chitosan with EDTAD to introduce carboxylic and tertiary amine functional groups, maintaining the secondary amines on the chitosan surface. Such a transformation was important not only to increase the adsorptive potential of chitosan but also to allow C1 to be used in acidic media, thus solving the problem of solubility of most chitosan derivatives. C1 was characterised by spectroscopic methods. The effects of solution pH, contact time and initial solute concentration on the removal of copper (II) and chromium (VI) by C1 were investigated in aqueous solutions. C1 showed an experimental maximum adsorption capacity of 106 mg/g for copper (II) and 194 mg/g for chromium (VI).

Published: February 2024

This article is devoted to the problem of social and psychological characteristics of female politicians who have achieved career growth in all industries where they work, including politics. It should be noted that this problem is a paradigm for Kyrgyzstan since the mentality of the Kyrgyz does not allow a woman to compete with a man on the same level. However, the conditions of the modern world force women to adapt to male culture. The author suggests considering the social and psychological image of a woman politician and the qualities that a woman must have in order to be successful in politics. This not only helps to identify the relevant qualities of a politician but also uses them to form the future image of a woman politician.

Authors:   University of World Economy and Diplomacy, Tursunova Ranokhon
Published: February 2024

An article about the gender equality of women in modern society on the example of Germany. The path of women in public life in Germany was difficult, but today German women have achieved great success in politics. Their number is growing both in political parties and in the country's parliament and in the structure of top leadership positions. For 16 years, the German chancellor was Angela Merkel, who led the country very successfully and is the first woman in this position and the third-longest rule in German history. At the present stage of modern history in Germany, there have been fundamental changes in the socio-political status of women, which can be described as positive. It should be pointed out that not only Germany but also the EU as a whole, has obliged the governments of all participating states to assist in resolving issues of equal rights for women and monitor the observance of their rights.
GENDER SOCIALIZATION AS AN OBJECT OF ETHNO-PSYCHOLOGICAL RESEARCH
Authors:   Osh State University, Umarov Talant
Published: February 2024

In the process of gender socialization, women and men learn traditional patterns of behavior, attitudes, norms, and values, as well as gender stereotypes. Philosophers, psychologists, and sociologists consider the problems of socialization and gender socialization in their theoretical paradigms, and they consider the process of socialization as “entry of the individual into the social sphere”, “social influence of the individual” and “acquisition of social roles”. In traditional societies, symbolic birth ceremonies are held depending on the sex of the child being born. Further, the child's clothes, cradle, and toys are determined by gender. There is no doubt that many ideas and thoughts in the cultural heritage have indeed become universal values. However, when the question of the social equality of men and women is raised, many contradictions arise in people who live by these values.

Published: February 2024

This article analyzes the political formation of modern gender issues. The unique features of the female perception of the world contrast with the active male dominance. Women in Kyrgyz society, their place in society, problems, responsibilities, connections, and relationships with men were analyzed. The struggle for a gender policy for social equality was discussed. Political processes with the regularity of gender relations were discussed. One area that clearly indicates inequality between the sexes is the inequality that exists along with employment or a work environment in which both female and male status exists. It has been studied that women spend more time with their children than with their fathers, even when they reach adulthood. The author draws attention to the need for legal solutions to gender conflicts in order to avoid destructive processes in the socio-cultural space.

The general provisions of matrix summation of Fourier series are also considered and examples of Ʌ-methods are given. In this paper, we show the process of solving by summation of Fourier series for some functions completely, starting with writing out the corresponding summed function. Further, this system is solved by one of the simplest, but often used linear methods of matrix summation of Fourier series.
BRAIN CHANGES WITH AGING
Authors:   Asian Medical Institute named after S. Tentishev, Khalilov Ilgar
Published: February 2024

The article presents the data of modern literature on the morphological changes in the brain during aging, the molecular mechanisms underlying their development, brain regeneration, and methods of its stimulation. The “oxidative damage” theory explains age-related changes by the accumulation of damaged mitochondria, which leads to progressive cell disorganization and cell death by apoptosis. In addition, the level of autophagy decreases, through which damaged organelles, intracellular pathogens and toxins, and abnormal proteins are removed from cells. The extremely limited regenerative potential of the brain of adult mammals, including humans, is associated mainly with the preservation of neurogenesis. By stimulating of this process we can slow down its aging.

When we carefully look at the path of growth and development of Kyrgyz literature, the main ideological and aesthetic trends, an endless and large-scale creative world is drawn before our eyes. Of course, every nation has its own spiritual manifestation. The pure spring flowing from that spring becomes a huge river, which gradually increases in size and rages. Today's Kyrgyz national literature seems to us to be a creative environment. Folk art, the poetry of singers, living in constant movement spontaneously, whose waves smashed mountains, are full of noble thought, wonderful words, songs accompanied by (“Manas”), caustic, flooding cheeks with laughter, is considered a treasure of jokes. Each of them was acquired in its own way by Kyrgyz scientists in special collective studies, but it is still clear that it is impossible to completely solve the above issues within the framework of one dissertation research or textbook.
