Research on hydrogen sulfide removal from water using a hydroejector
Authors: Zoria Olena , Ternovtsev Oleksiy , Tsyganok Mykola
Published: July 2024

The war in Ukraine has significantly impacted the country's water resources, leading to deteriorated water quality, threats to drinking water supplies, and long-term environmental issues. Intensive pollution of surface water sources has necessitated increased use of groundwater for drinking purposes.
The quality of groundwater in Ukraine varies greatly, often containing concentrations of iron, manganese, hardness salts, and hydrogen sulfide that exceed acceptable limits. Hydrogen sulfide concentrations in different regions range from 1 to over 20 mg/dm³, far exceeding the permissible limit of 0.05 mg/dm³ for drinking water. In the southern regions of Ukraine, such as Kherson, Mykolaiv, and Odesa oblasts, hydrogen sulfide levels exceed the norm by more than 100 times. Existing water purification methods for hydrogen sulfide require the construction of expensive aeration facilities with various loadings, biological reactors, and oxidation filters, which entail significant capital and operational costs. Moreover, these facilities do not always ensure the desired water quality. Therefore, developing new methods and technologies aimed at intensifying hydrogen sulfide removal from water, along with various devices and structures for their implementation, is a pressing issue related to supplying the population with quality water.
Among the developed approaches, the use of aeration as an independent method for purification is notable; however, it is used for low hydrogen sulfide concentrations and is most effective at low water pH levels. This article presents the results of experimental studies on the purification of groundwater from hydrogen sulfide by aeration using a hydroejector. Optimal parameters for the hydrogen sulfide removal process, depending on its concentration and water pH, were determined. The effectiveness of water purification using the hydroejector was substantiated and investigated. The key operational parameters of the hydroejector were established.
The influence of the conditions of applying sealing polymer materials on the deformation resistance of the sealanter to sclofibro concrete
Authors: Oleksiienko Olena , Vergun Lena
Published: July 2024

The article deals with the features of the treatment of solid surfaces with a primer before using sealing materials. The adhesive strength of the sealant to the area of adhesion is the basis for sealing the joints. Lack of adhesion leads to the ingress of water, dirt, precipitation and other climatic effects, which eventually lead to the destruction of the seams. Therefore, it is extremely important to observe the seam treatment technology before applying the sealant. Proper treatment of seams with a primer, observing the time of application to the base, before using sealing materials will increase the durability and service lifespan of the sealed joint.
To improve the adhesive strength between the adhesive and the substrate, as a rule, the hard surface (substrate) is pre-treated with a primer based on polyurethane foam or epoxy resins. These primers are used because when exposed to a hard surface, a polymer matrix is formed, which, upon further contact with the sealant, increases the adhesion strength in the contact zone. In surface defect zones with moisture content, a new surface layer is also formed due to the participation of polymer groups in forming intramolecular hydrogen bonds. The formation of a polymer layer on a solid surface containing defective zones requires a certain time.
Tests were carried out to determine the resistance to deformations of a combination of sealant/primer sealing materials in combination with glass fiber reinforced concrete samples and to establish the influence of the conditions for applying a primer/sealant to the surface of a glass fiber reinforced concrete composition on resistance to a series of character cycles of equal loads and temperature changes, with a deformation of the sealing material of 25% . It has been established that the time of treatment of a solid surface with a primer should be at least 5 minutes. If this condition is not observed when sealing materials are applied to glass fiber reinforced concrete, it may cause the sealant to separate from the base.

Introduction. Analysis of locomotor activity is essential in a number of biomedical and pharmacological research designs, as well as environmental monitoring. The movement trajectories of biological objects can be represented by time series exhibiting a complex multicomponent structure and non-stationary dynamics, thus limiting the effectiveness of conventional correlation and spectral time series analysis methods. Recordings obtained using markerless technologies are typically characterized by enhanced noise levels, including both instrumental noise and anomalous errors associated with false estimates of the location of the points of interest, as well as gaps in the trajectories, promoting an urgent need in the development of robust methods to assess the characteristics of locomotor activity.

Aim. Development of robust methods for assessing the characteristics of locomotor activity capable of efficient processing of noisy recordings obtained by markerless video-based motion capture systems.

Materials and methods. In order to assess the characteristics of locomotor activity, the relative movements of body parts of laboratory animals were analyzed using the stability metrics of the mutual dynamics of their trajectories, their relative delays, as well as the relative duration of the recording fragments when relatively stable mutual dynamics could be observed. The local maxima of the cross-correlation function of two body fragments, the minima of the standard deviation of the difference between their Hilbert phases, as well as their relative delays, were used as the metrics of mutual dynamics.

Results. The considered phase metrics were shown to explicitly reflect changes in locomotor activity, while the assessment of time delays using phase metric was shown to be prone to periodic error. The above limitation could be largely overcome using the correlation metrics, assuming that phase and correlation metrics could be combined.

Conclusion. The proposed robust methods provide stable estimates of the characteristics of locomotor activity based on markerless video capture recordings, altogether increasing the efficiency of diagnostic procedures and assessment of the therapeutic effect during rehabilitation.
Main peculiarities of the spread of early christianity in the Roman province of Africa
Authors: Beregovyi Vladyslav ,   Taras Shevchenko National University of Kyiv
Published: July 2024

The purpose of the article is to research the first origins of Christianity in the Roman province of Africa, to establish the geographical and chronological origin of early Christian doctrine in this region, and to determine the nature of its initial development. The research methodology is based on the principle of historicism and social approach. The article uses chronological, comparative historical approach, and analytical methods. The scientific novelty consists in the wide use of various source: written (early apologetic, hagiographic), archaeological and epigraphic, linguistic comparison of written sources, as well as the involvement of the latest historiographical research on Christianity in Roman Africa. Conclusions. Roman Africa underwent its initial Romanization after victory of Rome in the Punic Wars, and Proconsular Africa became a province of the Roman state in the first century B.C. The extensive trade network of Proconsular Africa with the Eastern and Western provinces of the Roman Empire contributed to the rapid urbanization and economic growth of the region. The constant trade and economic communication of the province made it possible for early Christianity to spread to the area. The first references to Christians date back to the second half of the second century AD and are typically written Christian texts of an urbanized nature. The Latin and Greek versions of these sources indicate the initial bilingualism of the early Christian ecclesia of Africa. The spread of Christianity in Africa came from both the Roman church and the churches of the Eastern provinces, and from there thanks to the Jewish trade diaspora. The beginning of the third century AD is characterized by the rapid development of the church in Africa and the work of the early Christian apologist Tertullian, who left behind a large written heritage. The earliest references to Christians in Proconsular Africa also indicate sporadic conflict between pagan society and local authorities against Christians.

Authors: Zadorozhnyuk Andriy ,   Kamianets-Podilskyi Ivan Ohiienko National University, Filinyuk Anatoliy ,   Kamianets-Podilskyi Ivan Ohiienko National University
Published: July 2024

The purpose of the article is to investigate the influence of Magdeburg laws on the economic development of Kamianets-Podilskyi, to find out the place and role of the application of German legal norms of city self-government in the evolution of guild craft production, to find out the essence, content, and specificity of Magdeburg workshop traditions in the broad chronological framework of life the largest Podillia city. The methodological foundation of the research is the principles of dialectics, objectivity, historicism, systematicity, and comprehensiveness. The research methodology is based on general scientific and special-historical methods, particularly analytical typology, documentary, historical-genetic, historical-typological, comparative-historical, problem-chronological, structural-systemic, etc. The scientific novelty lies in an attempt to scientifically reconstruct the permanent spread, implementation, and historical conditioning of the dominance of Magdeburg law in the production practice of the city over a long historical period. The novelty of the presented material lies in the interpretation, using the example of the main city of Podillia, of a complete system of production structures, which gradually transformed from medieval workshop organizations into powerful guild craft corporations of the New Age, which in some ways existed until the beginning of the 20th century. Conclusions. Our research proves that in the economic development of Kamianets-Podilskyi during the 14th - early 20th centuries, the factor of Magdeburg law played an important role. Magdeburg law went through several evolutionary stages of functioning, gradually covering and later shaping the economic life of Kamianets. Given the deep Magdeburg traditions in the system of organizing economic life, even after the annexation of Kamianets-Podilskyi by the Russian Empire, the city economy continued to function according to Magdeburg norms. In the 19th century, the Magdeburg production tradition continued to ensure the stability of the development of urban craft but gradually inhibited the development of new, more progressive forms of urban industry.

The purpose of the study is to show the main management practices used in the institution in 1947-1953 based on the analysis of the interaction between the administration and the staff of the Starynsky Orphanage of the Boryspil district of the Kyiv region. The research methodology. The scientific approaches are based on applying the methods of social history, everyday history, and microhistory. It included the general scientific methods of analysis, synthesis, comparison, systematization, and generalization. The scientific novelty lies in an in-depth study of the experience of organizing an orphanage. Its local management practices were studied, contributing to expanding knowledge about the structure, decision-making processes, personnel policy, and daily activities of such institutions in a difficult period for Ukraine. Conclusions. The Starynsky Orphanage was formed in the year when the network of special children's institutions of the Ministry of Education in the Kyiv region increased to 29 institutions. The orphanage was placed in one of the villages of the district, the infrastructure and economic situation of which best corresponded to the possibilities of quickly satisfying the pupils with a minimum of mandatory needs. A staff of 18-20 people was engaged in the arrangement. The work was organized in compliance with the standards stipulated by the state regulatory documents. The chief manager of the institution was the director. The scope of his powers included the following: reporting on compliance with legislation to representatives of a number of district bodies; establishment of cooperation with other local managers (management of collective farms, a sugar factory, a school, a rural hospital) and with state institutions of regional subordination, included in the system of social protection of orphans; formation of staff capable of qualitatively solving the assigned tasks. Since the situation with the selection of employees was difficult (high staff turnover), the directors practiced various ways of solving it: recommendations, a trial period, combining positions, replacement by qualified personnel from representatives of the local community, or at the request of district authorities, temporary redistribution of responsibilities within the team. The experience of management activities in the Starynsky Orphanage complements the understanding of the conditions the administration had to face to ensure the institution's smooth operation in conditions of limited resources and unpredictable circumstances.
Crimean Tatars in the historical and cultural heritage of Ukraine of the XV–XVII centuries
Authors: Vashchuk Dmytro ,   Institute of History of Ukraine National Academy of Sciences of Ukraine
Published: July 2024

The article aims to study the history of the Crimean Tatars of the XV–XVII centuries within historical cultural heritage materials. The territorial is limited to the Volyn region, namely the cities of Ostroh and Dubno. The study methodology is based on the principles of historicism and objectivity. Besides these principles, we use the principle of systematicity to study the documents. The factor analysis was effective in examining the social and political processes that took place in the late medieval and early modern periods. We also use the typological method considering material culture objects. Analytical and synthesizing methods were used to generalize the information obtained. The scientific novelty of the article lies in the fact that it studies the historical, cultural, and material heritage of one of the indigenous peoples of Ukraine - the Crimean Tatars in the late Middle Ages and early modern times. During the Ukrainian independence historians and archaeologists prepared some publications on the subject, but the generalized monographic study is absent. In addition, a significant part of material artifacts are kept in the collections of various museums and are not available in exhibition halls. Conclusions. The study of the Crimean Tatars’ material heritage on the territory of mainland Ukraine is important. Despite the rather complicated relations during the XV–XVII centuries, there are many examples of cooperation against common enemies, such as the Moscow state or the Polish-Lithuanian Commonwealth. Communities of immigrants from Crimea lived in many Ukrainian cities, towns, and villages, and together with the locals, they contributed to the common welfare and prosperity. All this has left a significant mark on the history, culture, and historical memory of different peoples. The presented artifacts of the Crimean Tatars from the collections of the museums of Ostroh and Dubno will contribute to the study and popularization of the cultural heritage of one of the indigenous peoples of Ukraine. We are firmly convinced that other Ukrainian museums (especially in their collections) hold many items related to the Crimean Tatars. Therefore, our research will continue.

The concepts of circular economy and sustainable development are recognized as the biggest challenges of today. Under such conditions, the issue of expanding the focus of the circular economy to the micro level, encouraging enterprises to transition from a linear model of the economy to circular (circular) one in conditions of economic uncertainty, is becoming actualized. Thus, the development of the theoretical basis of the concept of the circular economy of the enterprise and the formation of the definition «circular sustainability of the enterprise» as an indicator of the evaluation of the efficiency of recycling technologies. To solve the set goal, the main criteria of the circular economy were revealed in the course of the study, the differences between the circular sustainability of the enterprise, the circularity of the enterprise and the circular economy of the enterprise were characterized, the concept of the circular sustainability of the enterprise was developed, and the relationship of economic theories underlying the concept of circular sustainability was characterized enterprises. For greater thoroughness, the author investigated the following close categories: «circular economy of the enterprise», «circularity of the enterprise» and proposed a new category «circular sustainability of the enterprise». It is justified that these concepts are closely related, but not identical. The similarity between the categories is that they all aim to optimize the use of resources, reduce waste and increase efficiency in terms of environmental sustainability. The differences between the studied categories are determined by the level of application and concentration on specific aspects of management and strategy. It is substantiated that the «circular economy of the enterprise» focuses more on internal processes, the «circularity of the enterprise» covers interaction with the external environment, and the «circular sustainability of the enterprise» focuses on the long-term perspective and the inclusion of circular practices in the overall sustainability strategy. The theoretical basis of the circular sustainability of the enterprise as a symbiosis of economic theories was studied: systems theory, supply chain theory, product life cycle concepts, sustainability theory, closed loop economy theory, social responsibility theory, and innovation theory. Based on the results of the research, the author's concept of «circular sustainability of the enterprise» was developed

У статті проведено оцінку розвитку електронної комерції як форми торгівлі в цифровому середовищі. Авторами доведено, що електронна комерція сприяє підвищенню конкурентоспроможності постачальників, оскільки вони наближаються до своїх клієнтів. У роботі підкреслено, що у роздрібній торгівлі завжди існує потреба у збільшенні обсягів продажів та привертанні покупців, що призводить до зростання прибутковості. У роботі зроблено акцент на тому, що сучасна електронна комерція охоплює електронний обмін товарів через онлайн-платформи та Інтернет, мобільну торгівлю, електронні перекази грошей, керування ланцюгами постачання, Інтернет-маркетинг, онлайн-операції з транзакціями, електронний обмін даними (EDI), системи управління запасами та автоматизовані збір даних. Авторами доведено, що онлайн-ринки дозволяють займатися роздрібною підприємницькою діяльністю, шукати постачальників та покупців, оплачувати рахунки та укладати угоди, причому все це відбувається у межах глобального Інтернету. Водночас, для цього розробляються спеціальні норми і правила, створюється унікальне програмне забезпечення, проте основна ідея полягає в тому, що системи електронної комерції доступні всім, незалежно від їхнього місця перебування, оскільки вони функціонують у веб-середовищі. Разом з тим, авторами закцентовано увагу на тому, що організації з доступом до Інтернету використовують різні види електронної комерції, які відповідають їхнім потребам, масштабам, цілям і принципам роботи. Інтернет-торгівля, банкінг, страхові послуги і грошові перекази можуть бути використані однаково успішно та одночасно, залежно від специфіки кожної компанії. Авторами доведено, що роздрібна електронна торгівля є невід’ємною частиною сучасної економіки, і її зростання залежить від ряду факторів. Серед них важливими є приплив нових користувачів Інтернету, особливо активних мобільних користувачів, та загальна тенденція цифровізації суспільства. Отже, ці фактори сприяють мінімізації витрат на операції та транзакції через глобальну мережу. Такий розвиток роздрібної електронної торгівлі підтримує її зростання і дозволяє компаніям збільшувати обсяги продажів та підвищувати конкурентоспроможність на ринку.

Стаття присвячена вивченню актуальних аспектів міграційних явищ в Україні. Здійснюючи глибокий аналіз, досліджено динаміку міграційних потоків, враховуючи комплексний вплив економічних, соціальних і політичних чинників на ці процеси. Основну увагу присвячено ідентифікації ключових тенденцій, що визначають міграційні потоки в Україні, і розгляду рекомендацій стратегій державного регулювання, враховуючи їх ефективність і наслідки для економіки та суспільства. Особливу увагу у статті приділено вивченню впливу війни в Україні на міграційні процеси, розкриваючи його комплексний вплив на масштаби та напрями міграції, зосереджуючись на факторах втрат робочих місць, соціальної нестабільності та загроз безпеці. Стаття враховує не лише кількісні аспекти міграції, але і динаміку змін у структурі міграційних потоків під впливом внутрішніх та зовнішніх факторів. Цей підхід дозволяє отримати більш глибоке розуміння взаємозв'язків між військовими діями та міграційними явищами. Окрему увагу приділено ролі державного регулювання в управлінні міграційними процесами, зокрема в контексті створення сприятливого середовища для інтеграції мігрантів та мінімізації негативних впливів на економіку та соціум. Досліджуються конкретні стратегії та методи, які можуть сприяти успішній інтеграції та зменшенню негативного впливу міграційних процесів. Зокрема, рекомендовано акцентувати увагу на розвиток програм інтеграції, спрямованих на підтримку освіти, здоров'я та соціального захисту населення. На основі аналізу робляться пропозиції щодо вдосконалення та оптимізації стратегій державного регулювання міграційних процесів в Україні. Висуваються конкретні напрямки для поліпшення ефективності регулювання, які ґрунтуються на виявлених тенденціях та результативному аналізі. Такий підхід сприятиме створенню ефективних механізмів управління міграційними потоками в умовах внутрішніх та зовнішніх викликів, забезпечуючи стійкість суспільства. Дослідження служить основою для розробки конкретних стратегій, спрямованих на оптимізацію міграційних процесів та підвищення їхнього позитивного впливу.
