Исследовано влияние микроструктуры на усталостные свойства и механизмы разрушения бурильных труб из алюминиевых сплавов 1953Т1 и Д16Т. Определен химический состав труб в различных участках, проведены испытания на статическое растяжение и многоцикловую усталость. Исследованы структура и поверхности разрушения образцов после испытаний. Установлено, что более прочный a-твердый раствор и наличие упрочняющих интерметаллидов MgZn2 и Al2CuMg в структуре обеспечивают сплаву 1953Т1 более эффективное сопротивление зарождению усталостной трещины, чем сплаву Д16Т с менее прочным a-твердым раствором и частицами Al2CuMg и Al2C. Предел выносливости трубы из сплава 1953Т1 составляет 192 МПа, а из сплава Д16Т — 179 МПа. Однако отношение предела выносливости к пределу текучести алюминиевого сплава Д16Т достигает 40 %, а сплава 1953Т1 — всего 32 %. Такой эффект предположено связан с более высоким запасом пластичности и однородности структуры сплава Д16Т, чем сплава 1953Т1.

Development of a Method for Assessing the Quality of Public Transport Services within Urban Transportation Planning Systems
Authors: Andreev S. A.
Published: April 2024

This article discusses the issues of assessing the perceived quality of services provided by ground urban passenger transport. The implementation of a marketing approach to development of transport services means the need to consider the opinion of a potential consumer regarding a planned or completed trip. Integrating the perceived quality of transport services into development and implementation of urban transport policy will allow us to shape more effectively sustainable transport behaviour, focusing on taking measures that give the greatest return, maintaining the loyalty of existing passengers and attracting new ones.

Based on the focus of the transport service on the final consumer, the article analyses methods for assessing quality indicators for the transport chain. The issues of using a gravity model to assess the quality of amultimodal transport chain are considered with the account for the point of view of an individual passenger and user groups.

Promising Areas of Research for Developing Single Approaches to Assessing the Quality, Dependability and Efficiency of Traffic Management
Authors: Gorbunov R. N. , Gorbunova Z. V. , Kolchin V. S.
Published: April 2024

The article provides proposals for improving the efficiency of traffic management using geoinformation data. The objective of the research is to identify promising areas of research to develop single approaches to assessing quality, dependability, and efficiency of traffic management using relevant criteria.

The authors reviewed these criteria from the point of view of regulatory documentation and noted the possibility of using models of urban road networks to find optimal modes of managing traffic at minimal cost. Since previous studies showed the lack of single approaches and clear criteria for optimising traffic management, it was proposed to comprehensively consider the possibility of assessing traffic not only from a technical point of view, but also from the point of view of approaches used in management theory.

As a tool of assessment of the efficiency indicators of traffic management, a time cost function was proposed, which is the sum of the time costs for all the road users. Increasing the efficiency of traffic management is achieved by minimising this function. It is also noted that when the time cost function is reduced, the material costs of road users, such as fuel costs, are reduced.

Having examined the principles of functioning of road traffic in other countries, the authors identified two approaches to management of traffic on the road network: mechanistic and organic ones. Mechanistic approach presupposes strict respect of the rules by all the road users, while organic one presupposes the ability to deviate from the rules. The authors presented examples of selforganisation of traffic on sections of the road network of the city of Irkutsk, which is an example of application of an organic approach to organising traffic in Russia.

The article results in development of several promising areas of research, due to which uniformity of approaches to selection and formation of requirements for indicators of depedability, quality and efficiency of traffic management can be achieved.
Development of Proposals for Increasing the Efficiency of Using Domestic High-Capacity Rolling Stock in the South of Russia
Authors: Rakhaev V. A. , Kuzina E. L. , Vasilenko M. A.
Published: April 2024

The main trend in development of high-capacity rolling stock used in the South of Russia is specialisation of coaches. The article considers the advantages of double-decker trains compared to traditional single-decker trains. Double-decker trains make it possible to carry out multimodal transportation of passengers in conditions of increased demand and a decrease in alternative offers from other modes of transport, increase the capacity of passenger rolling stock, the transit capacity of the railway infrastructure, and ensure the most rational use of the dimensions of the rolling stock. As a result, the carrying capacity of railway lines increases with minimal costs since energy costs for traction and traction-related costs are reduced.

The authors analysed and constructed a model for replacing traditional single-decker rolling stock with more spacious doubledecker rolling stock. The dependence of the volume of traffic on passenger flow and a potential area of replacing single-decker trains with double-decker trains are shown. A nomogram is presented for the dependence of the volume of transport services for the population on the regularity of train schedule. A general algorithm for assessing and selecting potential opportunities for assigning double-decker trains in the South of Russia is considered.

Scenarios have been proposed for changing the category of transport services under the conditions of increased demand while replacing single-decker cars with double-decker ones. The annual effect from replacing single-decker cars with double-decker ones was calculated together with the total investment effect.
Unification of Passenger Trains when Organising Irregular Railway Transportation
Authors: Panova O. N. , Vakulenko S. P. , Egorov P. A.
Published: April 2024

Passenger transportation by rail can be divided into regular (travelling with labour or recreational purposes, weekend trips), and irregular (tourist, rotational, migration and others). The organisation of regular transportation is based on medium- and long-term planning of number of transported passengers, which is not applicable to irregular transportation.

Determining the optimal layout of a passenger train, the number of main types of sleeping cars (with compartments and reserved seats without compartments) is one of the key tasks in organising railway passenger transportation, including irregular one.

One of the promising improvements in development of longdistance railway passenger transportation is unification of passenger trains, which makes it possible to organise a comprehensive rotation of trains, thereby reducing non-operational downtime and increasing the efficiency of using rolling stock.

Studies to assess the optimal composition of a long-distance train were carried out for regular railway transportation. However, considering several features of irregular passenger transportation, such as short-term planning of the volumes, high differentiation in the number of groups of passengers, a possibility of using free seats on trains on existing routes, it is necessary to re-evaluate the effectiveness of using unified passenger train composition schemes under these conditions.

The development of standard compositions of passenger trains is carried out using the cluster analysis method. The use of three unified compositions is proposed. When developing proposals for unifying the layouts of passenger trains in circulation, it is necessary to consider the additional passenger traffic in irregular transportation, which cannot be absorbed using the remaining free seats. The results of the study were applied to a fragment of the North-Eastern part of railway network.

Published: April 2024

Background: In recent years, blockchain technology has made great strides in diverse industries but has fallen behind within the pharmaceutical industry. The pharmaceutical industry is complex and would benefit greatly from the distributed database and emphasis of information privacy promoted by blockchain technology. This paper identifies the potential best application for blockchain technology in the United States pharmaceutical industry by identifying current trends, companies exploring the possibilities of blockchain technology, and industry concerns with opportunities for improvement.

Methods: We utilized a 4D framework using ease of implementation, novelty, necessity, and fit of the overall industry to examine the adoption of blockchain technology in the pharmaceutical industry. Based on the 2D framework of difficulty and novelty as driving factors for the development of foundational technologies in the world of business by Iansiti and Lakhani in The Harvard Business Review, each application was ranked and scored for the best potential implementation. The potential applications proposed in this paper can be grouped into two main categories. The first category, management, includes best use cases such as health records, clinical trials, and inventory systems. The second category, monitoring, highlights cases such as pharmaceutical products, preventing counterfeits, optimizing supply chains, and addressing prescription misuse and abuse.Results: Each application was ranked by the four metrics in the framework, giving the greatest weight to necessity and ease of implementation. Using the highlighted methodology above, the applications for best implementation include Prescription Drug Misuse and Abuse Prevention, Prevention of Counterfeits, Clinical Trial Outcomes, and Smart Contracts.

Conclusion: Blockchain technology offers a new and promising solution to pharmaceutical industry needs. Each application of blockchain technology must fit within the framework of necessary, ease of implementation, familiarity amongst stakeholders, and fit of the overall industry to promote the most appropriate use.  By using the extended framework proposed by Iansiti and Lakhani we show that blockchain, in all these domains, shows promise to improve pharmaceutical industry performance.
MONTAGE AS A FORM OF ARTISTIC THINKING IN THE WORKS OF UKRAINIAN AVANT-GARDE ARTISTS
Authors:   Ivan Franko National University of L’viv, Department of Theatre Studies and Acting, PROKOPCHUK Inna
Published: April 2024

The study aims to highlight the concept of understanding the category of montage as a cultural phenomenon that realizes itself as a formative principle of cultural morphology and represents the artistic embodiment of the worldview and socio-cultural attitudes of modernism. Without pretending to be comprehensive, the research focuses on the artistic and technological universality of montage as a tool of artistic perception and reflection of reality in various types of art of the Ukrainian avant-garde of the first third of the twentieth century. On the basis of scientific works,the author determines the representativeness of montage in its species variants, the carriers of which are artistic works designed from elements with different spatial, temporal, iconographic, and stylistic nature. It is noted that montage in the building of works of art has been used since ancient times, before the appearance of the term itself, one of the main creative techniques and an independent artistic phenomenon it became only in the culture of the twentieth century, in the era of modernism and postmodernism that followed. The author sees further study of montage as one of the meaning-forming principles in the artistic and aesthetic system of postmodernism with a tendency to merge not only different types of art, styles, genres and forms, but also the general intellectualisation of art. The artistic experiments of the Ukrainian avant-garde artists were directly inspired by the birth and spread of cinema, on the one hand, and played a key role in its evolution as a new art form, on the other. The artists’ radical discoveries in the representation of modernity, the peculiarities of the city, and the crowded street gave rise to montage theories based on the principles of counterpointing the frames of the reflected reality. Moreover, the montage language, as an element of artistic thinking of the era, became a leading way of understanding the organization of action in the nature of the new life, and the best artists turned to it in their radical search for new forms and content.
THE THEATRICAL AND CRITICAL JOURNALISM OF “YOUNG MUSE” THROUGH THE PRISM OF MODERNIST VISIONS IN THE FIRST DECADE OF THE 20TH CENTURY
Authors:   Ivan Franko National University of Lviv Department of theater studies and acting, TSYHANYK Мyroslava
Published: April 2024

The early 20th century in world art was a vibrant period as it inspired enthusiasm for everything from eStablished traditions, and relinquished widely accepted norms of artiStic interpretation. Modernism and the avant-garde gradually transformed all artiStic fields, shaping a new rhetoric for Stage art and, consequently, theatrical criticism. It was during this period that Ukrainian theatrical criticism emerged, one of the branches of theater Studies. As an active participant in the process, it formulated the terminological dictionary and phraseology of theatrical criticism. The key theater Studies processes of the firSt decade of the 20th century took place within the “Young Muse” group, which included well-known Ukrainian theater theoriSts such as S. Charnetsky, M. Rudnytsky, V. Birchak, P. Karmansky, B. Lepy, O. Lutsky, and S. Tverdokhlib. They advanced theatrical criticism in Galicia, developed concepts for representing Stage art in Ukraine, and viewed it through the prism of the pan-European theater Studies paradigm from the late 19th to the early 20th century. The text suggeSts that through the textual analysis of reviews by the “young generation” literary movement, the focus was typically on the play’s title and its author. The discussions revolved around the dramaturgy, mentioning directors, actors, Stage decorations, and occasionally the audience’s reactions. The themes of these reviews were aimed at describing the theatrical consciousness of the era, and the StyliStic expression captured new theatrical terminology and phraseology. The semantic interpretation of these elements always requires a broader context of Study. The publications by the “young generation” are intereSting not only in terms of the Structure of theatrical-critical texts but also in the information that shapes the model of theater in Galicia in the firSt half of the 20th century. This model can be further explored in accordance with its evolution. The “Young Muse” generation of theater critics has taken a significant place in the formation and development of theater Studies as a science. They hold a prominent position in the sourcebased content of the hiStory of Ukrainian theater in Galicia.
THE FIELD OF (NON-HYBRID) BATTLE AND THE UKRAINIAN INTELIGENTSIA

Published: April 2024

The Start of russia’s full-scale invasion of Ukraine on February 24, 2022, became a watershed between two worlds for Ukrainians and the global community. After the ambivalent existence between the Russian-speaking and Ukrainian-speaking cultural space of independent Ukraine, the time came to define clear positions and actions for every Ukrainian, artist, actor as well. The slogan “Art over Politics” became irrelevant, the exposed nerves of dramatic events required taking only one, true side in the battle. In the difficult early hours of the war, the critical border situation, the peaceful Ukrainian people transformed from a somewhat infantile, apolitical mass of vita minima people to a vita heroica. Ukrainian journalists, actors, singers, artists joined the defense of the country both on the battlefield as well as the cultural front, experiencing in the tense times of war and armed aggression the people’s special need for a high quality and creative national product. ArtiSts became more active, realizing that art, culture, and creative industries perform several important functions for Strengthening the mental spirit of the people and its patriotic surge. SuggeStive, heuristic, hedonistic, communicative, social, nation-building functions dominate among many cultural and artistic expressions.

La ciprofloxacina, componente activo en la terapia del síndrome inflamatorio intestinal, es un antibiótico del grupo de las fluoroquinolonas. La Administración Nacional de Medicamentos, Alimentos y Tecnología Médica (ANMAT) establece la técnica de HPLC con detección UV como método de referencia para cuantificar su contenido en comprimidos. Si bien la titulación potenciométrica de este fármaco con bases fuertes es insatisfactoria, el hidróxido de amonio facilita su cuantificación haciendo uso de la primera y segunda derivada de la curva. Por lo tanto, se propone una potenciometría indirecta haciendo uso de este titulante. Optimizado el método y aplicado a comprimidos de ciprofloxacina 500 mg es lineal en el rango de 0,7 a 1,5 mg/ml. Ensayos efectuados con placebo, indican que los excipientes no interfieren. La recuperación del principio activo es de 99,8- 100,2%. La precisión, expresada como repetibilidad, condujo a un CV de 0,45% y la precisión intermedia, para días y analistas diferentes, acusa CV< 2%. Los resultados son comparables en términos de exactitud y precisión (1es1 1 P< 0,05) a los del método de referencia.
The advertisement call of Argenteohyla Siemersi Pederseni (Amphibia, Anura, Hylidae), and comments on its taxonomic status

Two subspecies of Argenteohyla siemersi, nominate A. s. siemersi and A. s. pederseni, are currently recognized. It was suggested that analysis of nuptial calls and chromosome structure would contribute to clarify their taxonomic status. In this paper we describe the advertisement call of Argenteohyla siemersi pederseni from Reserva Natural Provincial Iberá, Corrientes, Argentina, and comment on its taxonomic status. The advertisement call of A. s. pederseni is quite variable in duration and number of notes. Additionally, it seems to perform synchronized duets. The call of A. s. pederseni is similar to that of A. s. siemersi in note structure and duration, but the fundamental frequency and the number of notes for call were higher in A. s. pederseni than in A. s. siemersi. These data suggest that siemersi and pederseni could belong to different biological species, although further work is needed to support this assertion.
Abundancia de Caminicimex Furnarii (Cordero y Vogelsang) (Heteróptera: Cimicidae) en nidos de Golondrina Doméstica Progne Chalybea (Gmelin) (Passeriformes: Hirundinidae)

Se brindan por primera vez datos sobre densidad, estructura poblacional y proporción de sexos de C. furnarii (Cordero y Vogelsang) en nidos de Golondrina Doméstica Progne chalybea (Gmelin). Tres nidos fueron colocados en embudos Berlese para calcular el número y las proporciones relativas de huevos (66,4%), ninfas (11%) y adultos (22,6%). La proporción de sexos se encontró sesgada hacia los machos (1,61). El número de chinches/nido fue elevado y varió entre 210 a 1163; en el menos infestado de los nidos habría entre 30 y 42 chinches/golondrina, y en el más infestado, entre 166 y 233. El ciclo de las chinches está ajustado a largos períodos de inanición antes del regreso de las golondrinas en la siguiente estación reproductiva.

Background: Uterine sarcoma, frequently diagnosed postoperatively, and often misidentified as benign tumor, is commonly managed through minimally invasive surgery (MIS) and tumor morcellation. This study aims to investigate the survival outcomes of MIS for early-stage uterine sarcoma, and investigate the impact of tumor morcellation on oncologic outcomes. Methods: A retrospective study was conducted on 33 patients diagnosed with early-stage uterine sarcoma and were studied from January 2006 to December 2022. Patients were divided into two groups: MIS group and open group. This study assessed the 5-year progression-free survival (PFS) and overall survival (OS) in both groups. Additionally, the study investigated the impact of tumor morcellation on oncology outcomes. Results: The 5-year PFS rates in the MIS and open surgery groups were 42% and 65%, respectively (p = 0.577); the 5-year OS rates were 77% and 56%, respectively (p = 0.125). Sixteen patients had recurrence (48%). The 5-year PFS rates in the morcellated and nonmorcellated groups were 42% and 51%, respectively (p = 0.732); the 5-year overall survival rates were 75% and 68%, respectively (p = 0.584). Conclusions: Although there were not statistically significant differences in survival outcomes between the MIS group and open surgery, intraoperative tumor morcellation may increase peritoneal recurrence risk and negatively affect progression-free survival. Further, a large study is needed to investigate the outcomes of MIS.

Background: The objective was to explore the impact of different delivery methods on maternal and infant outcomes in women with a prolonged second stage of labor and a fetus with a persistent occipital posterior position. Methods: 60 women with a fetus in the occipital posterior position who underwent obstetric low forceps-assisted delivery were selected as the study group according to the order of delivery, and 40 women who underwent cesarean section during the same period were selected as study group 1 according to the order of delivery. We compared the maternal-related indicators and neonatal outcome-related indicators of the two groups. Then, we selected women in chronological order during the same period to be included in control group 2 (60 primiparous women with a fetus in the occipital anterior position who underwent low forceps-assisted delivery during the same period) for comparison with the study group. Results: The time of fetal head delivery, postpartum hemorrhage rate, hospitalization time, average hospitalization cost, and number of cases of postpartum infection in the group with a fetus in the occipital posterior position and low forceps-assisted delivery were significantly lower than those in the cesarean section group (p < 0.05). There was no statistically significant difference in the 1-minute Apgar score, umbilical artery blood gas pH value, or number of neonatal injuries between the cesarean section group and the group with a fetus in the occipital posterior position with forceps-assisted delivery (p > 0.05). There were also no statistically significant differences in the complication-related indicators between the group with a fetus in the occipital posterior position with forceps-assisted delivery and the group with a fetus in the occipital anterior position with forceps-assisted delivery. The two groups had second-degree lacerations, cervical lacerations, vaginal wall lacerations, and vaginal wall hematomas. There was no statistically significant difference in the comparison of urinary retention (p > 0.05), and there was no statistically significant difference between the group with a fetus in the occipital posterior position and forceps-assisted delivery and the group with a fetus in the occipital anterior position and forceps-assisted delivery in the comparison of related indicators of neonatal outcomes and pelvic floor reexamination at the Aa and Ap points 42 days after delivery (p > 0.05). Conclusions: The use of low forceps for women with a prolonged second stage of labor and a fetus in a persistent occipital posterior position can effectively shorten the time of fetal head delivery, reduce postpartum bleeding, reduce the incidence of postpartum infection, shorten the hospitalization time, and reduce average hospitalization costs and does not increase adverse neonatal outcomes.
