Published: August 2023

In this study, the researchers investigate the structural relationships between the consumption value of vegetable-based meat substitutes, customer satisfaction, and repurchase intention. Six hundred twenty-six consumer copies were used for analysis, and AMOS 23.0 and SPSS 25.0 were employed to analyze data. The findings of this study are as follows. First, functional, personal, and ecological values among the consumption values of vegetable-based meat substitutes were found to have significant and positive effects on customer satisfaction, while altruistic value was not. Second, all components of consumption value for vegetable-based meat substitutes were not found to have significant and positive effects on repurchase intention. Third, customer satisfaction was found to have a significant and positive effect on repurchase intention. Based on these findings, the current study highlights the necessity of the marketing strategy focusing on personal benefits such as convenience and utility obtained by consuming vegetable-based meat substitutes. Furthermore, this study suggests that improvement in customer satisfaction needs to be prioritized as a health-oriented food, and consumers' perception of vegetable-based meat as a significant alternative food remarkably induces continuous consumption of vegetable-based meat substitutes.

Published: August 2023

The low-cost formate salt was used as the reductant and part of the carboxyl source in a visible-light-driven dicarboxylation of diverse alkenes, including simple styrenes. The highly competing hydrocarboxylation side reaction was successfully overridden. Good yields of products were obtained under mild reactions at ambient temperature and pressure of CO2. The dual role of formate salt may stimu-late the discovery of a range of new transformations under mild and friendly conditions.
Parameterization of general organic polymers within the Open Force Field framework

Published: August 2023

Polymer and chemically modified biopolymer systems present unique challenges to traditional molecular simulation preparation workflows. First, typical polymer and biomolecular input formats, such as protein data bank (PDB) files, lack adequate chemical information needed for the parameterization of new chemistries. Second, polymers are typically too large for accurate partial charge generation methods. In this work, we employed direct chemical perception through the Open Force Field toolkit to create a flexible polymer simulation workflow for organic polymers, encompassing everything from biopolymers to soft materials. We propose and test a new input specification for monomer information that can, along with a 3D conformational geometry, parameterize and simulate most soft material systems within the same workflow used for smaller ligands. The monomer format encompasses a subset of the SMIRKS substructure query language to uniquely identify chemical information and repeating charges in under-specified systems through matching atomic connectivity. This workflow is combined with several different approaches for automatic partial charge generation for larger systems. As an initial proof-of-concept, a variety of diverse polymeric systems were parameterized with the Open Force Field toolkit, including functionalized proteins, DNA, homopolymers, cross-linked systems, and sugars. Additionally, specific properties were computed for PEG, PNIPAAm, and PAAm homopolymers to demonstrate a start-to-finish workflow for high-throughput simulation and property prediction. It is expected that this work will greatly expedite the day-to-day computational research of soft-matter simulations and create a robust atomic-scale polymer specification in conjunction with existing polymer structural notations.
Tunable valence tautomerism in lanthanide-organic alloys

Published: August 2023

The electronic structures of the lanthanide (Ln) ions are inimitable and key to advanced materials and technologies. The trivalent ions are ubiquitous and dwarf the use of di- and tetra-valent analogues, which, however, possess vastly different optical and magnetic properties. Hence, alteration of the valence electron count by external stimuli would lead to dramatic changes in materials properties. Compounds exhibiting a temperature-induced, complete Ln(III) ⇄ Ln(II) switch, referred to as a valence tautomeric (VT) transition, are virtually absent. Herein, we present an abrupt and hysteretic VT transition in a lanthanide-based coordination polymer, SmI2(pyrazine)3, driven by the interconversion of closed-shell Sm(II)-pyrazine(0) and paramagnetic Sm(III)-pyrazine(●–) redox pairs. Alloying SmI2(pyrazine)3 with Yb(II) yields isomorphous Sm(1–x)Yb(x)I2(pyrazine)3 solid solutions with VT transition critical temperatures ranging widely from 200 K to ~50 K at ambient pressure. These findings demonstrate a simple strategy to realize thermally switchable magnetic materials with chemically tunable transition temperatures.

Authors: Kuchechuk Larysa
Published: August 2023

Food is the primary need of any human being, which is why the food security at the both national and global levels is always important. The subject of this research is the global food security. The purpose of this article is to analyze the current state of global food security, identify its main challenges and development trends of recent years. To achieve the goal of this article the author sets and solves following tasks, namely, analyzes different approaches to defining the concept of «food security» and the number of starving people in the world and in its regions for the period 2005-2021, identifies the main challenges for the world food security. General scientific methods were used to achieve the goal of research: analysis, synthesis, systematization, comparison, abstract-logical method. The results of the research show that number of starving people both quantitatively and in percentage terms from 2005 to 2018 almost constantly decreased, and from 2019 began to grow steadily. The author notes that the largest number of starving people live in Asia, and the largest percentage of the undernourished population live in the African region. Since 2020 global food security has worsened significantly, and the main reason for this was the global COVID-19 pandemic, because of which the starving people number began to rise rapidly across the planet. The main negative impact was manifested in the population income decrease and an food prices increase. In addition, the negative consequences of the COVID-19 pandemic were also manifested in the reduction of food production, namely, the access of small producers to the necessary resources was reduced, some food products demand decreased due to the closure of public catering establishments, and also there was a temporary suspension of exports. The author highlightes that at the beginning of 2022 a new global food security challenge appeared, it was the Russian-Ukrainian war. Due to the stopping of Ukrainian exports, record food prices were observed, which significantly worsened the access of the low-income population to food products. After the signing of the grain agreement and the resumption of Ukrainian grain exports, the situation stabilized. Conclusion: a steady deterioration of global food security has been observed since the beginning of 2020, the main cause of which was the COVID-19 pandemic, and in 2022 appeared a new challenge, Russian-Ukrainian war.

Published: August 2023

The article is based on a thorough analysis of the most relevant works of the world’s leading scientists engaged in research in the field of gastronomic tourism. It reveals the main aspects of the development of the famous French restaurant guide «Michelin», which is very important today in the world of haute cuisine, culinary tourism and the art of living. The subject of the article is the study of the main trends in the evolution of the red guide, which during the 20th century passed through three stages – at first it was a technical guide that offered information about goods and services for drivers, later it turned into a tourist guide, and, finally, it was transformed into a gastronomic guide. The purpose of the paper is to analyze the role and the significance of this guide for gastronomic tourism. The history of the French company for the production of car tires «Michelin», the activities of the founders brothers André Michelin and Édouard Michelin, the creation of its symbol Bibendum, the development of the guide itself, and the search for ways to form the optimal principles of cuisine quality classification are described. Attention is also paid to the professional activities of the most famous female chefs, who have been awarded Michelin stars. To achieve the goal, such research methods as historical, descriptive, comparative ones, systematization and generalization were used. Today, the Michelin red guide is published for many worldcountries and for the largest metropolises, the company started publishing the guide-magazine «Food & Travel», launched the «Michelin Green Star» award to recognize restaurants that particularly adhere to sustainable gastronomy, and also launched production of kitchen utensils. It has been established that the best chefs in the world strive to turn their business into business empires, not content with just receiving Michelin awards. They actively write culinary bestsellers, participate in the filming of reality shows, films and TV programs, found schools, and also work in the format of takeaway food and food trucks. At the same time, it was revealed that gastronomy business caused constant stress, consumption of alcohol and drugs by chefs, bullying, significant financial burden, ratings pressure, criticism of Michelin rating system approaches, fear of losing business and suicide. The obtained results make it possible to supplement and expand specialized training courses in higher education institutions of Ukraine, where personnel for tourism and hospitality industry are trained. So, in the course of its historical development, the red guide «Michelin» has become the most famous culinary guide in the world, aimed at ensuring that customers get maximum pleasure from visiting restaurants.
FEATURES OF FORMATION OF PRIMARY AND SECONDARY INCOMES OF THE POPULATION: THEORETICAL ASPECT AND REALITIES IN UKRAINE
Authors: Urchik Gаlina
Published: August 2023

This article is devoted to the theoretical and analytical study of the peculiarities of the formation and distribution of incomes of the population. Based on the synthesis of existing scientific achievements, we have determined the order of formation of primary and secondary incomes by stages of GDP distribution. We provе that the first stage of distribution of the created GDP is formed by factor primary incomes (from labor activity, property and productive capital). Thereafter, the redistribution of income occurs through the use of the fiscal mechanism and the accumulation of funds in public financial funds, from which secondary incomes such as wages of public sector employees, military salaries, scholarships, social benefits, pensions, social insurance payments and other social transfers are paid. Based on the analysis, we find that the share of primary income in Ukraine prevails over secondary income (57% vs. 43% in 2020). It is substantiated that the formation and distribution of personal income in Ukraine is characterized by the following main patterns: the growth of primary income is significantly higher than secondary income (the exception was only in 2020); the share of primary income tends to increase, and the share of secondary income decreases. We state that wages and salaries account for more than 60% of primary income, while social benefits and current transfers account for almost 80% of secondary income. Important sources of secondary incomes in Ukraine are the consolidated state budget and the Pension Fund (in their total expenditures, almost half and more than two-thirds, respectively, are the basis for the formation of secondary incomes). The author’s calculations showed that in Ukraine, almost half of all secondary incomes of the population are redistributed through the consolidated state budget and the Pension Fund (with a corresponding distribution of 30% and 13-23% during 2014-2020). At the same time, the level of redistribution of total income through these public financial funds is significantly lower (24.8-29.3% during 2014-2020). We prove that not only primary incomes are a factor in the formation of secondary incomes, but also secondary incomes determine the growth of factor incomes through the so-called multiplier effect, which is manifested in the following pattern: formation of secondary incomes → formation / growth of consumer demand → GDP growth → growth of primary incomes in terms of those employed in the production of relevant goods and services. During 2014-2020, secondary income in Ukraine led to expanded GDP growth, as the multiplier of social expenditures in Ukraine ranged from UAH 1.19 to UAH 1.65. Finally, the paper calculates the increase in primary income due to the multiplier effect of secondary income (the corresponding increase ranged from UAH 318 billion in 2014 to UAH 922 billion in 2020).
DIRECTIONS OF SECURING THE BANKING SYSTEM OF UKRAINE AGAINST THREAT TO ITS FINANCIAL SECURITY AND ELIMINATING RISKS IN THIS SPHERE
Authors: Lagno Anastasya
Published: August 2023

The purpose of this article is to determine directions for securing the domestic banking system from threats to its financial security and eliminating risks in this area. The state of the banking system of Ukraine shows that its financial security is under the influence of numerous threats and risks in this area. However, today there is no effective system for ensuring the financial security of the domestic banking system, which is due to the lack of logically completed studies to clarify the essence and types of such security, identify threats to it and risks in this area, proper security activities with the identification of various effective security measures and perfect risk management. Therefore, the solution of the mentioned problem requires a clear definition of the components of security activities to secure the banking system from threats and eliminate risks, which should include a well-founded complex of analytical, monitoring, organizational and resource provisioning measures. An important place in securing the banking system of Ukraine from threats and minimization/elimination of risks in the banking sector should belong to the perfect banking infrastructure, in which the infrastructure for ensuring the security of banking activity should also become significant. Full and timely detection of threats not only to the financial security of the banking system in general, but also to its deposit, credit, currency, investment, debt, inflation, and profit-making security in particular is necessary to fully protect the domestic banking system from threats to its financial security and eliminate risks in this area. Improving the identification of threats to the FS of the banking system and risks in this area in order to increase the level of its FS will contribute to: development and implementation of the Concept of securing the FS of the banking system, capable of adapting to newly emerging threats and risks and optimizing the costs of securing the FS of the banking system in general and its structural elements; application for monitoring and analytical activities of the system of security indicators, determination of their threshold values and deviations from them of the available indicators of the functioning of the banking system in order to take measures to ensure the functioning of the banking system. For a more justified application of these indicators, it is advisable to divide them into target groups. Legally distinguish institutional / structural-institutional and monetary indicators, indicators of resource, deposit, credit, currency, debt, investment, inflation security, financial condition, payment systems.

The functional features of cryptographic technologies in combination with decentralized data registries gave impetus to the development of the segment of decentralized financial assets. Evolutionarily, special decentralized applications were created that ensure the correct operation of the entire DeFi ecosystem. This work is devoted to the study of decentralized applications, since this is the main link of the market of decentralized finance, which provides an interface for the interaction of market subjects. In our work, we study the architecture of decentralized applications in particular detail. In the course of the work, we analyzed the dynamics of the creation of new decentralized applications on the main networks of the ecosystem. We found that most modern applications were created between 2017 and 2019, but new and newer use cases for decentralized applications are constantly emerging. We also identified and outlined the main categories of decentralized application architecture components. We added to the external parts of the architectural components: application developer, blockchain developer, application user, contract user, token user, consensus provider; and internal architectural components: client, smart contract, token, blockchain platform, other platforms. Several examples of the operation of blockchain protocols and the principles of transaction confirmation are in work. We created a detailed diagram of the interaction of all parts of the architecture, as well as subjects participating in the work of applications. We also explained the difference between tokens and coins, as well as accompanying conclusions regarding the practical side of the difference of decentralized assets. We also highlighted several features of the functioning of parts of the architecture of decentralized applications, in particular, management methods and the organization of interactions between different protocols in the middle of the DeFi ecosystem. We have also made appropriate conclusions on the work.

Haque’s Approach with Mickens’ Iteration Method is used to find the exact analytic solution of the nonlinear equation involving velocity times acceleration squared. A truncated Fourier series is used in different rhythms with different repetition steps. Our results are very close to the exact results and our results are comparatively closer to the exact results than others. Our solution method is obtained around the second-order angular frequency using Newton’s method. For some third-order (jerk) differential equations with cubic nonlinearities and nonlinear second-order differential equations; Mickens’ iteration method is used to determine the exact analytical approximate periodic solution. A numerical experiment of general differential equations with third-order, one-dimensional, autonomous, quadratic, and cubic nonlinearity has uncovered several algebraically simple equations involving the shaking of time-dependent acceleration that contain chaotic solutions.
ENERGY CONSERVATION BY NEW ENERGY-EFFICIENT MOTORS AND CONFIDENCE INTERVAL FORECASTS USING STATISTICAL TECHNIQUES
Authors: Khooharo Murtaza  Ali
Published: August 2023

As the most energy-intensive machines on the planet, induction motors are the subject of an ongoing study to increase their effectiveness. In this respect, new energy-efficient motors (NEEMs) are being developed. For increasing energy conservation, motors with efficiencies considerably higher than traditional standard motors (TSMs) and energy-efficient motors (EEMs) have been suggested. NEEMs have the potential to save a significant quantity of energy as well as operating costs. A comparative study is conducted in this paper to show how much energy and cost can be saved if TSMs in various industries in Pakistan are replaced with NEEMs, as well as their payback period. A data sample of 23 motors of different ratings has been collected in this pilot study and 90 percent confidence limits are calculated using a t-distribution. The energy conservation benefits of the NEEMs are found encouraging

CARBON STORAGE POTENTIAL OF DOMINANT MANGROVES IN WESTERN INDIAN SUNDARBANS
Authors: Mullick Poulomi
Published: August 2023

The Indian Sundarbans are noted for luxuriant mangrove diversity that is known to scrub carbon dioxide from the atmosphere. Precise estimation of the biomass of these species is necessary for evaluating the carbon storage pattern in the mangroves of the lower Gangetic belt. The plant biomass estimation was carried out for an average of 25 trees in 15 (10 m × 10 m) plots from the intertidal mudflats of Chemaguri (southeast portion of Sagar Island) in low tide conditions from 10th to 15th September 2022. The estimated biomass was of the order Sonneratia apetala > Avicennia alba > Avicennia marina > Excoecaria agallocha > Avicennia officinalis. The stem, branch, and leaf biomass of each species were converted into carbon by multiplying with a factor of 0.45 as per the standard procedure. The deviations observed in the results obtained from both studies call for the standardization of the process.

Published: August 2023

In this study, the nonlinear Landau-Ginsberg-Higgs (LGH) model is proposed and examined. The stated model is applied to analyze superconductivity and drift cyclotron waves in radially inhomogeneous plasma for coherent ion-cyclotron waves. This is undeniably a robust mathematical model in real-world applications. The generalized exponential rational function method (GERFM) is utilized to extract the suitable, useful, and further general solitary wave solutions of the LGH model via the traveling wave transformation. Furthermore, we investigate the effects of wave velocity in a particular time limit through a graphical representation of the examined solutions of the model to understand the dynamic behavior of the system.

The paper attempts to provide some insight into development and make suggestions for improvement of students’ work-based learning (WBL) and practical placements based on the analysis of some WBL cases in European universities. These proposals aim to improve the quality of education and ensure the decent employment of the graduates. The large-scale survey of employers revealed their high interest in the admission of students for practical placements.
The proposals for the organization of WBL and practical placements based on close university-business cooperation were set forward within the ERASMUS+ project «UniLab – From university to labour market in the 21st century: a step forward in work-based placements” which embraced seven countries, including Russia with four university participants.
Theoretical and empirical analysis of the EU cases helped the project partners identified some future-proofed tools for the Russian HEIs.
To achieve the goals set in the project, the following methods were used: document analysis, literature review, study the best experience of the UniLab partners, and the survey of companies.
The article makes contribution to the existing volume of research and knowledge related to the university-business partnerships, and suggests positive steps that need to be taken for upgrading WBL efficiency.

Analyzing the infectious morbidity of the population, it should be noted that the predominant places in the general structure belong to such nosologies as influenza and SARS, which more than 35 million citizens get sick in the country every year. In this regard, the generated economic damage reaches, according to various sources, 50-100 billion rubles /year, while the total damage from the entire group of infectious diseases ranges from 80-125 billion rubles/year. Due to the fact that the peak incidence occurs in the autumn-spring period, it is at this time that the greatest demand for antiviral drugs (LP) is noted.
Due to the high variability of the antigenic structure of RNA-containing viruses (more than two thousand variants of strains) and the airborne transmission pathway, which increases the distribution area, data infections are widespread among the population and are registered annually not by single outbreaks, but cause a wave of epidemics with a lethality of 250-650 thousand people/year. The greatest danger of these viruses is for people with not yet formed and (or) weakened immunity: children, pregnant women, the elderly, especially if it occurs not in mild or moderate, but in severe or toxic forms, causing a number of complications.
The article presents an overview of the research of the Khabarovsk Territory pharmaceutical market of drugs for the treatment of influenza, acute respiratory viral infections for the period of 2016-2020. The aim of the research was to study the consumption range of drugs for the treatment of influenza and ARVI in the Khabarovsk Territory of the Russian Federation. Based on the data obtained, we can draw conclusions on the quality of this region’s pharmaceutical care to the population with influenza and ARVI in the period under review.

El índice de mortalidad de los pacientes que han sufrido un accidente cerebro vascular isquémico es elevado, pero el índice de pacientes con secuelas neurológicas y motoras debido a la lesión focalizada del cerebro es aún mayor. Los pacientes que sobreviven a la isquemia encefálica producida por una lesión cerebral focal necesitan cuidados crónicos para recuperarse o por lo menos compensar las funciones motoras y sensoriales que se deterioraron durante el accidente. El diagnóstico debe estar acompañado de la clínica y la imagenología, para así poder realizar un tratamiento efectivo e inmediato. A continuación, se presenta el caso de un paciente de 60 años, masculino, que a la edad de 46 años y durante las horas de la madrugada sufre un accidente cerebro vascular. Al momento del ingreso el paciente presenta síndrome isquémico cerebral izquierdo acompañado de afasia motora y de hemiplejia derecha. En tomografía axial computarizada simple de cráneo se descarta hemorragia, y se procede a iniciar terapia antitrombótica. El tratamiento inmediato permite una evolución muy favorable a los pacientes, incluso disminuyendo las secuelas neurológicas secundarias a la enfermedad.

Antecedentes: Según la Organización Mundial de la Salud (OMS), se define a la diabetes mellitus tipo 2 (DM2) como “un grupo de trastornos metabólicos caracterizados por una condición de hiperglucemia si no se recibe tratamiento adecuado”, esta problemática afecta al 8,5% de la población mundial. Objetivo: Determinar la prevalencia de riesgo para desarrollar diabetes tipo 2, mediante aplicación del test FINDRISC, y factores asociados en la población adulta del cantón Pucará-Azuay, entre marzo y mayo del 2023. Metodología: Investigación observacional, descriptiva de corte transversal, a realizarse con IC 95% en la población adulta del cantón Pucará provincia del Azuay en el periodo marzo a mayo del 2023. La población del estudio está compuesta por personas adultas que residen en la zona urbana del cantón Pucará, constituida por 1122 personas en la cabecera cantonal, se utilizó la ecuación de tamaño muestral para universo finito y se realizó un muestreo aleatorio simple, dando como resultado 211 participantes necesarios para la muestra. Resultados: La mayor parte de la muestra estuvo compuesta por mujeres representado por un 59,7%, la media de edad en el sexo femenino fue de 40,57 años, el peso de 66,19 Kg y la talla de 154,10 cm, en cuanto al sexo masculino la edad media fue de 39,61 años, el peso de 73,14 Kg y la talla de 167,38 cm, la prevalencia del riesgo alto fue del 5,2% y muy alto del 0,9%, la mayoría de variables tuvieron asociación con un valor de p<0,05, con excepción de la frecuencia de consumo de fruta. Conclusiones y relevancia: Una porción considerable de la muestra presenta características de riesgo relacionadas a la categoría de alto y muy alto, sin embargo, las prevalencias para estas mismas categorías como se expuso en los resultados son considerablemente bajas de manera general, dado que en la mayor parte de variables se evidenció una posible asociación, se pudiese inferir que el test FINDRISC resultad de gran utilidad como método preventivo.
