Published: November 2024

У статті досліджується роль державної політики у розвитку туристичної галузі в Україні, зокрема, через аналіз чинної нормативно-правової бази та державних стандартів та визначення напрямів їх вдосконалення. Туризм є важливим сектором національної економіки, який сприяє економічному зростанню, створенню робочих місць та покращенню міжнародного іміджу країни. Проте для ефективного розвитку галузі необхідна сучасна, комплексна та добре скоординована державна політика, яка б враховувала сучасні виклики, зокрема, глобалізацію, цифровізацію та зростаючу конкуренцію на міжнародному рівні. Визначено, що чинне законодавство має фрагментарний характер, часто містить застарілі положення, які не відповідають сучасним потребам ринку, і не забезпечує належного рівня координації між різними рівнями влади. У статті виявлено низку ключових проблем у сфері нормативно-правового регулювання туризму, зокрема, відсутність інтеграції з європейськими стандартами, неврахування нових форм туризму, недостатня увага до питань безпеки та адаптації до кризових ситуацій. Відсутність сучасних механізмів підтримки галузі, зокрема, в умовах воєнних дій та пандемії COVID-19, обмежує спроможність туристичної галузі адаптуватися до змін і розвиватися. Пропонується модернізувати законодавство з урахуванням міжнародних стандартів, розробити інтегровану стратегію розвитку туризму, що включатиме чіткі механізми реалізації, фінансування та контролю за виконанням. Окрему увагу слід приділити розвитку інновацій у сфері туризму, підтримці нових видів діяльності, таких як екотуризм і цифрові туристичні послуги, а також удосконаленню процедур ліцензування та спрощенню умов для малих і середніх підприємств. Висновки статті підкреслюють необхідність системного підходу до державного регулювання туристичної галузі, що передбачає гармонізацію національного законодавства з європейськими стандартами, розвиток міжвідомчої координації, залучення міжнародних інвестицій та активну промоцію туристичного потенціалу України на світовій арені. Реалізація запропонованих заходів сприятиме підвищенню конкурентоспроможності українського туризму, стійкості до сучасних викликів та забезпечить сталий розвиток галузі в довгостроковій перспективі.

Authors: Martínez-Jiménez Laura , Agenjo-Calderón Astrid
Published: November 2024

Este artículo analiza la in/visibilización del trabajo de cuidados en la ficción televisiva a través de la serie La maravillosa Señora Maisel. Fundamentado en el marco teórico-interpretativo de la economía feminista, el estudio se lleva a cabo mediante el análisis crítico del discurso y se operativiza en cuatro dimensiones discursivas: el sentido de clase de los trabajos de cuidados, su hiperfeminización, su implicación en la re-producción de la feminidad y la tensión dicotómica entre la domesticidad y el empleo. Así, La maravillosa Señora Maisel supone una sugerente oportunidad para estudiar la multidimensionalidad, la (des)organización cotidiana y los peajes disciplinantes del trabajo de cuidados en íntima conexión con la feminidad, así como con sus expresiones de clase y raza.

Navigating the US-China Trade War: Implications for Pakistan
Authors: Farooq Arshad  , Muhammad Kamran Malik
Published: November 2024

The present study explores the implications of the trade war between the United States and China, with a focus on its security implications for Pakistan. The trade war between the world's two largest economies has resulted in escalating tariffs, trade restrictions, and increasing protectionism. As a major trading partner of both the United States and China, Pakistan finds itself caught in the crossfire of this economic conflict. From an economic standpoint, Pakistan has faced several challenges due to the trade war. The disruption in global supply chains and reduced bilateral trade between the US and China have adversely affected Pakistan's exports and foreign direct investment. Pakistan's economy heavily relies on exports to both countries, particularly in sectors such as textiles, electronics, and agriculture. Furthermore, the trade war's security implications for Pakistan are multifaceted. As tensions between the US and China have escalated, both countries have sought to gain influence and strategic advantages in various regions, including South Asia. Pakistan, being a significant player in the region, has experienced intensified competition for influence. The US has sought to deepen its partnership with Pakistan to counterbalance China's growing economic and military presence in the region, while China has expanded its investments and infrastructure projects in Pakistan under its Belt and Road Initiative. The security implications for Pakistan in the context of the trade war also involve regional dynamics. Pakistan shares a border with China and maintains a complex relationship with India, which has its own geopolitical interests in the region. The shifting alliances and power dynamics resulting from the trade war could potentially affect Pakistan's security environment and its ongoing challenges, such as the Kashmir dispute and terrorism.

To date, in the world zinc production, the main share of zinc consumption up to 50% is accounted for by the processes of galvanizing products. An important factor affecting the efficiency of the hot-dip galvanizing process is the loss of zinc associated with the formation of surface (zinc burn) and bottom (gartzink) waste. Of great interest for the processing of dross is the use of metal chlorination technology. The optimal technological parameters of the firing process were established in the work, where deep sublimation of impurity metals was achieved to obtain pure zinc oxide, suitable for use as a mineral additive in animal and bird feed. It was found that the use of a mixture of chlorinating reagents with a consumption of CaCl2 and NH4Cl of 3% and 7%, respectively, provides high-quality commercial zinc oxide with a minimum content of impurities, % wt: 0.02 Pb; 0.04 Fe; 0.01 Ni; 0.01 Cu; Cd traces. Optimal technological parameters and firing process modes were established: temperature – 1000°C; duration – 60 minutes; chlorinating reagent – mixture (CaCl2 + NH4Cl): CaCl2 consumption – 3% of the weight of the initial sample; NH4Cl consumption – 7% of the weight of the initial sample; air consumption – 0.1 l/min. In this paper, the results obtained will be used to conduct balance experiments on firing the oxidized component of the dross together with chlorinating reagents.

The issues the strength of the chassis design of a multi-purpose reconnaissance robot are considered. The object of study is the part of the turning unit, which is ABS plastic. For this part, the parameters of shear forces and bending moments were determined for the first time depending on the specified external distributed loads of 0.125 to 2.5 kN/m. The optimal limiting values of bending strength and shear forces arising when loading distribution loads are determined. To determine the shaft rotation angle and lateral displacement (deflection), the initial parameters method was used, the values of which were 6° and 1 mm, which is an acceptable result for this type of wheeled reconnaissance robot. To ensure the reliability of the obtained theoretical results, computer simulation for displacement was additionally applied. The analysis revealed minor deviations from theoretical indicators, which allowed us to conclude that the calculations were correct.

An analysis of some modern methods of processing copper smelter slags containing iron, copper and other valuable components was carried out. Obviously, for deep complex processing, a combination of pyro and hydrometallurgical methods is necessary in order to use the positive qualities of both methods. So iron in the form of a finished product of iron and steel can only be extracted by pyrometallurgical methods, and non-ferrous metals are extracted using hydrometallurgical methods. The use of force fields at the leaching stage can also have a positive effect on the efficiency of processing.

The results of a research of the fluxes usage effect on the physicochemical properties of sinter from mill scale are presented. The conducted studies have shown the expediency of introducing fluxes into the composition of the sintering charge. However, each flux in the form of quartzite or limestone (dolomitic) has its own advantage. When quartzite is used as a flux, X-ray phase analysis and microsection of the agglomerate confirm the presence of metallic iron. The introduction of limestone (dolomitic) into the sinter charge allows to produce a fluxed sinter. When using sinter for metal smelting, the fluxed sinter will allow limestone to be removed from the furnaces. The conclusion of which leads to the saving of a significant amount of heat spent on dissociation СаСО3 and MgСO3, thus saving fuel. Magnesio-ferrite formation (MgFe2O4), periclase (MgO), alumina in fluxed sinter is primarily due to the use of limestone (dolomitic). Magnesium contained in limestone dissociated with magnetite to form MgFe2O4 and MgO. To confirm the reliability of X-ray phase analysis, samples of the fluxed agglomerate were examined by scanning electron microscopy with the INCA Energy microanalysis system. Also, the average elemental composition of the sinter according to EDS analysis is shown in the figures and tables.

In the modern world, rare metals are a sought-after sector. But, like all other resources, rich rare metal deposits can be depleted quite quickly. Thus, there is a tendency towards the discovery of new and detailed additional exploration of already known rare metal deposits. Since the main rare metal structure of East Kazakhstan is the Kalba-Narym belt, this justifies the relevance of its study. The Central Kalba region has been well studied and devel oped thanks to well-known industrial deposits (Yubileinoe, Bakennye, Belogorskoe, etc.). The remaining areas are by no means unpromising for rare metal mineralization. North-Western Kalba, as well as the entire Kalba-Narym metallogenic zone, is characterized by a rare-metal profile of ore mineralization associated with the formation of granites of the Kalba complex. The authors consider the genetic classification of deposits and ore occurrences in North-West ern Kalba based on a detailed study of a large amount of factual material. The main practical value in the area is represented by rare metal deposits of the formation of rare metal pegma tites of the albite type.
Another Look at the Security Analysis of the Modulus N = p2q by Utilizing an Approximation Approach for ϕ(N)
Authors: Aqlili Ruzai Wan Nur , Nek Abd Rahman Normahirah , Asbullah Muhammad Asyraf
Published: November 2024

Newly developed techniques have been recently documented, which capitalize on the security provided by prime power modulus denoted as N = prqs where2 ≤ s < r. Previousresearchprimarilyconcentrated on the factorization of the modulus of type at minimum N = p3q2. In contrast, within the context of 2 ≤ s < r, we address scenarios in the modulus N = p2q (i.e. r = 2 and s = 1) still need to be covered, showing a significant result to the field of study. This work presents two factorization approaches for the multiple moduli Ni = p2 iqi, relying on a good approximation of the Euler’s totient function ϕ(Ni). The initial method for factorization deals with the multiple moduli Ni = p2 iqi derived from m public keys (Ni,ei) and is interconnected through the equation eid − kiϕ(Ni) = 1. In contrast, the second factorization method is associated with the eidi − kϕ(Ni) = 1. By reorganizing the equations as a simultaneous Diophantine approximation problem and implementing the LLL algorithm, it becomes possible to factorize the list of moduli Ni = p2 iqi concurrently, given that the unknowns d, di, k, and ki are suff iciently small. The key difference between our results and the referenced work is that we cover a real-world cryptosystem that uses the modulus N =p2q. In contrast, the previous work covers a hypothetical situation of modulus in the form of N = prqs.

Published: November 2024

The purpose of this study was to theoretically elaborate the model of formation of customer experience of service organisations at the conceptual level and to conduct a study using the developed tools for its evaluation on the example of the hotel business. The main results were based on the principle of holistic personalism and are obtained using the methods of field marketing research, questionnaire survey of respondents, scoring and index method. The data were processed and analysed using statistical correlation analysis, graphical and matrix approaches. The Customer development methodology was used to form a chain of positive customer reactions. The article substantiates a conceptual model of formation of customer experience in service organizations based on the principles of behavioural theory. The article allocates 2 groups of factors on the example of hotels that form the customer experience: explicit and implicit, and includes 6 factor attributes. Three types of customer experience are distinguished: before the moment of consumption of the product – the expected experience (CX ex en.), at the moment of consumption – as the perceived customer experience (CX at the time), and intentions for future consumption of the service product (CX ex post). To assess them, 4 marketing metrics were proposed to evaluate each type of customer experience. To interpret the results, the values of the indicators are scaled. The carried out testing of the proposed methodology on a sample of 14 four-star hotels confirmed the hypotheses of the study. The proposed theoretical concept and evaluation tools can be further used to develop marketing programmes for Customer Experience Management (CXM)

The purpose of this study was to determine how leasing transactions contribute to business modernisation in Kyrgyzstan. The study used survey methods and semi-structured interviews with company representatives, followed by statistical analysis of the collected data to determine changes in productivity, operating costs, and investment payback period. In particular, the results showed that 90% of the surveyed agricultural enterprises reported a 25-30% increase in productivity after using leasing to purchase machinery, which was confirmed by analysing data on the reduction of repair and maintenance costs for old equipment. In transport logistics, 85% of the companies indicated a reduction in operating costs and improvement of logistics processes due to fleet renewal through leasing programmes, which also contributed to an increase in the customer base by 15-20%. In the construction sector, the use of leasing allowed 82% of companies to reduce project completion time by 20-25%, which was due to the acquisition of new construction equipment through leasing, which can accelerate the performance of work and improve the quality of projects. In the manufacturing sector, 70% of companies reported a positive impact of leasing on their production capacity, but a longer payback period was identified, which requires the development of specialised leasing programmes with more flexible terms for industrial enterprises. The results of the study confirmed the important role of leasing as a financial instrument for the modernisation of enterprises in Kyrgyzstan, but also reveal the need to improve the access of small enterprises to leasing programmes and adapt the conditions for sectors with a long investment cycle, such as manufacturing

Published: November 2024

This study focused on analysing the role of diversification as a tool that enables businesses to adapt to changes in the external environment, mitigate risks, and ensure sustainable development. The study explored the main types of diversification: horizontal, vertical, concentric, and conglomerate. Each type of strategy has its own distinct characteristics, benefits, and risks. Horizontal diversification allows companies to expand their product range by utilising existing resources and knowledge, facilitating rapid entry into new markets. Vertical diversification offers the opportunity to control the supply chain or distribution channels, reducing reliance on external partners and enhancing operational efficiency. Concentric diversification enables companies to expand their business by leveraging existing competencies and technologies, thereby minimising risks. Conglomerate diversification, although the most risky, allows businesses to enter new industries unrelated to their core operations, potentially increasing profits. Successful use of different diversification strategies to achieve market leadership is illustrated by companies such as Disney, Tesla, and Mironivsky Hliboproduct (MHP). Tesla employed all types of diversification, controlling every stage of the production of its electric vehicles, including the creation of infrastructure for charging stations. Disney also implemented diversification by expanding its presence through the acquisition of studios, the development of theme parks, and the launch of streaming services. MHP demonstrated examples of diversification by controlling the entire production chain from raw materials to finished products, while also expanding its range of meat products. The conclusion emphasised the importance of a cautious and well-considered approach when selecting a diversification strategy, considering available resources, market opportunities, and the specific characteristics of the business. Successful implementation of a diversification strategy allows companies not only to reduce risks but also to strengthen their position in the face of volatile economic conditions and competitive pressure

Authors: Ketners Karlis , Jarockis Aleksis , Petersone Mara
Published: November 2024

The study aims to improved the state budget system to ensure informed decision-making, which will contribute to more efficient use of budget funds and increase national financial stability. A comparative analysis of successful budget planning practices in other countries, such as Sweden, Canada and Estonia, was conducted, and the legal framework for coordination between government agencies in the budget management process in Latvia was reviewed. The methodological approach was based on the analysis of statistical data from official sources and regulations, as well as the use of information from government and ministerial websites. The results of the study showed that the analysis of revenues and expenditures of the Latvian state budget for the period from 2019 to August 2024 revealed a steady increase in revenues, with the exception of a decline in 2020 due to the pandemic, and an increase in expenditures, which requires optimisation and better coordination between government agencies. The study determined that the existing legal framework of Latvia regulating coordination between state institutions in budget management needs to be improved to increase the efficiency of this interaction. A comparison of Latvia's budget management systems with the successful practices of Sweden, Canada and Estonia demonstrated management improvement potential by introducing long-term strategic planning, as in Sweden, integrating results into the budget process, as in Canada, and increasing transparency and public involvement, as in Estonia. Based on the data obtained, recommendations were developed to integrate new technologies into the budget process and increase transparency, contributing to a more efficient use of public resources. The results indicate the need to reform the state budget system to ensure informed decision-making in Latvia. This will make it possible to use budget funds more rationally, increase the transparency of financial processes and strengthen public confidence in government decisions
Towards Learning Activity Cliff-Aware Molecular Representations
Authors: Valdez Córdova César Miguel
Published: November 2024

Current deep learning based methods for molecular property prediction show pronounced shortcomings when predicting molecular properties in the presence of activity cliffs (AC): pairs of structurally similar molecules with significant differences in potency. We investigate how inductive biases of increasing complexity, from simple Multilayer Perceptrons (MLPs) to selfsupervised models, impact the learning of representations from Extended-connectivity Fingerprints (ECFPs). Leveraging the Matched Molecular Pair (MMP) abstraction, we explore various pre-training schemes designed to capture AC relationships. While simple models remain competitive, we show extensive differences and avenues for potential improvement in performance across different inductive bias choices and pre-training strategies, paving the way for AC-aware and consequently, chemically robust model design.

Oxadiazoles, a class of nitrogen-containing heterocycles, exhibit diverse applications in pharmaceuticals, industry, and other fields. This study employs Density Functional Theory (DFT) to investigate the structural, electronic, and spectroscopic properties of four oxadiazole isomers. The B3LYP functional and the 6-311G(d,p) basis set were used for calculations. Frontier orbital energies, energy gap, chemical reactivity descriptors, dipole moment, and thermodynamic properties were computed. Additionally, IR and UV spectra were analyzed. The results indicate significant variations in electronic and thermodynamic properties among the isomers. Isomer 4 demonstrated the highest stability and electrophilicity. The calculated IR and UV spectra were compared with available experimental and theoretical data. The study provides valuable insights into the structural and reactivity trends within the oxadiazole family, contributing to a deeper understanding of their potential applications.

Published: November 2024

This study employs Molecular Electron Density Theory (MEDT) to explore the [3+2] cycloaddition mechanisms involving 1-methyl-4-(prop-1-en-2-yl)cyclohex-1-ene (2-R) and nitrile oxide (3-R). Density Functional Theory (DFT) calculations using the B3LYP/6-311(d,p) method were performed to determine reactivity indices, activation energies, and reaction energies. The conceptual DFT analysis indicates that 1-methyl-4-(prop-1-en-2-yl)cyclohex-1-ene 2-R acts as a nucleophile, while nitrile oxide 3-R functions as an electrophile. The reaction exhibits notable chemoselectivity and regioselectivity, supported by activation energies that align with experimental data. BET analysis suggests a one-step mechanism with asynchronous bond formation. Additionally, molecular docking studies of the reaction products against HIV-1 and COVID-19 reveal that the presence of oxygen and nitrogen atoms enhances the interaction energy with proteins, indicating potential therapeutic benefits.

This article presents the first stage of work on the implementation of the project for the creation of an installation for testing fusion materials at WWR-K reactor using the vacuum extraction method. In particular, the data of calculations of the vacuum system of the installation for various geometries of the vacuum path are presented. The developed model made it possible to estimate the range and distribution of pressures along the length of the irradiation device and the vacuum system. The obtained values of the pressure distribution showed that, in general, the physical ability to register the flow of tritium and helium into the system will be sufficient for the levels of production of tritium and helium in the samples under study above 10-11 mol/s.

Authors: Alexandrova Zh. N.
Published: November 2024

Soil phyto-remediation technology is proposed, that lies in plants seeding with maximal ability for radioactive elements accumulation, forage content disposition and its further utilization. Accumulation ability of 67 vegetation types (both cultivated and native) were studied, range of transition factors change, reaching three orders (from thousandths to tenth of units). During research an approximate theory of phyto-remediation was proposed. Technology was experimentally approved during field study of the East-Uralsk radioactive trail. Phyto-remediation time evaluation in condition of Semipalatinsk Test Site enables to assume, that the current technology is prospective for other territories also.

The work related to the study of the inclusive spectra of secondary protons produced in the interaction of protons with energies of 30.0 MeV with the nucleus 58Ni. Double-differential and integral cross sections of (p, xp) reaction have been received with further determination of their total partial cross sections. The analysis of the experimental spectra is based on a modified version of the exciton model of pre-equilibrium decay in the frame of code PRECO-2006. The contributions of compound, preequilibrium and direct mechanisms to the formation of the integral cross section are calculated. The experimental results can be used in developing new approaches in theory of nuclear reactions, as well as the design of safe and non-waste hybrid nuclear power plants.

Published: November 2024

The contribution of Kazakhstani stations has been suumarized in comparison with other stations of the International Monitoring System (IMS) in a number of associated phases into the REB bulletin (Reveiwed Events Bulletin) of the International Data Center (IDC). It has been demostrated that all stations of Kazakhstan, both seismic and infrasound ones, are quite effective in monitoring and take one of the first places. This is confirmed by the results of mapping of the epicenters of the events of the world as well as such parameters as minimum amplitude and proportion of a number of events detected with participation of Kazakhstani stations to the general number of events in REB. The region of Central Asia (CA) has been considered in detail in the REB results as well as bulletins of Kazakhstan National Data Center (KNDC) – seismic and infrasound – with examples of estimate of real-time accuracy of locations. Infrasound bulletin of events of KNDC on CA has been compared with REB. In KNDC bulletin the location has been implemented as per data of four infrasound stations, including one Russian station Zalesovo. A larger number of events has been noted in KNDC bulletin in comparison with the REB one.

APPLICATION OF INTEGRATED GEOPHYSICAL RESEARCH FOR ON-SITE INSPECTION OF NUCLEAR TESTS
Authors: Botov A. A. , Romanov A. M.
Published: November 2024

In order to improve and develop methods of geophysical control for the purposes of on-site inspection, especially at the sites with limited access, that are suspicious in implementation of a nuclear test, it is proposed to use a new view on interaction of rocks and water. According to this view, one can establish leached zones, migration zones and deposits of matter (including radioactive one) in real geological conditions remotely by using electrical survey methods. In order to detect hydrodynamic structures that pass via UNE foci, tritium exhalation measurements are used – the main marker of distribution of radioactive contamination from UNE foci. The eligibility of these views has been proved theoretically, experimentally and by geophysical surveys in real conditions of Semipalatinsk Test Site.

Authors: Usmanova M. T. , Sattarova A. M.
Published: November 2024

In article, distribution of space-temporal seismic activity of Western Tien-Shan region was considered. Two groups of strong earthquakes in Western and Central Uzbekistan were extracted. Regularity has been detected on redistribution of the accumulated tectonic energy in the form of seismicity alternatively on the regions. It was shown that earthquakes on hypocenters’ depths were distributed in certain seismogenic layers independent from their magnitude level. Deflections were discovered from the regularity of grouping of strong earthquakes in seismic regime of the region. Probably natural and technogenic triggers preceded the triple strong Gazly earthquakes in 1976 and 1984 with М=7,0–7.3. Natural triggers: active processes of fissures on the north Gazly with length ~ 100 km near Tamdibulak and absence for more than 40 years of appreciable earthquakes in epicentral region Gazly. Technogenic triggers: constant 40-years-long gas pump from “Gazly” fields and two nuclear explosions implemented near Gazly earthquakes in 1976 and 1984 of tectonic nature.

Published: November 2024

Experimental results on the relaxation of internal stresses in structural stainless steels Х18Н9Т, 12Х18Н10Т and AISI 316 after neutron irradiation, effects of stationary or pulsed electrons of various powers are presented. It has been established that in steels irradiated with low neutron fluxes (1016 ÷ 1018 n/cm2), the deformation by extension as a result of relaxation phenomena is the martensitic γ → α transition begins at lower values of critical stresses than after austenization. At the same time, there is an anomalous effect of reducing the yield strength and reducing the amount of mechanical workexpended on the destruction of the steel sample. The features of the relaxation of internal stresses and the formation of the α-phase in stainless steels under irradiation with electrons of various energies are revealed. It is shown that the radiation relaxation of internal stresses caused by the action of neutrons, pulsed or stationary electrons, changing the conditions for the formation of the α-phase, determines the level of mechanical and corrosion properties of irradiated stainless steel.
