Authors: ФАТЫХОВ М.А. , ФАТЫХОВ Л.М. , АКЧУРИНА В.А. 
Published: September 2024

Образование асфальтеносмолопарафиновых отложений (АСПО) в нефтепромысловом оборудовании приводит к частому снижению полезного сечения насоснокомпрессорных труб и нефтепроводов, к полному перекрытию подъемных труб и кольцевых каналов в межтрубном пространстве, что требует проведение ремонтных работ скважин. На основе анализа материалов научнотехнической литературы установлено, что в ряде случаев одним из эффективных методов предупреждения образования АСПО и борьбы с ними является использование энергии высокочастотных (ВЧ) и сверхвысокочастотных (СВЧ) электромагнитных полей. В статье исследованы процессы нагрева и расплавления парафиновой пробки в стволе нефтяной скважины движущимся источником электромагнитного излучения СВЧ диапазона. Осуществлены расчеты пространственновременных зависимостей температуры в трубе, рассматриваемой как круглый волновод. Показано изменение времени полного расплавления парафиновой пробки в зависимости от структуры электромагнитного поля.
Education of wax deposition in oilfield equipment leads to frequent reduction of the useful crosssection of pumpcompressor pipes and oil pipes, to the complete overlap of the risers and the annular channels in the annular space, which requires repairs of wells. On the basis of the analysis of materials of scientific and technical literature it is established that in some cases one of the effective methods of prevention and control of the formation of wax deposition is the use of energy of highfrequency (HF) and microwave electromagnetic fields. In the article the processes of heating and melting of paraffin plug in the oil well barrel by moving source of electromagnetic radiation of microwave range are investigated. Calculations of spacetime dependences of temperature in a pipe considered as a round waveguide are carried out. The change in the time of complete melting of the paraffin tube depending on the structure of the electromagnetic field is shown.
Generalization of passed: Gliere’s music in «The Mad Day, or the Marriage of Figaro» of Moscow Art theatre (1927)
Authors: Наумов А.В. 
Published: September 2024

Статья посвящена одной из самых известных режиссерских работ К.С. Станиславского спектаклю Безумный день, или женитьба Фигаро по комедии П.К. Бомарше, поставленному в 1927 году в Московском Художественном театре с музыкой Р.М. Глиэра. Эта постановка неоднократно описана в литературе второй половины ХХ века, но с разных, не смыкающихся между собой точек зрения. Целью настоящего исследования является суммирование данных для составления наиболее полной картины культурных обстоятельств, связанных с жанром театральной музыки как таковым и его развитием в ХХ веке. Участие крупного композитора в работе великого театра дает возможность сопоставления партитуры Безумного дня с другими театральными сочинениями Глиэра, а также с музыкой к другим постановкам МХАТ. Охватывается также более широкий спектр проблем, встающих в связи с бытованием драматургического первоисточника и принципиальной вариантностью его музыкального оформления в разных сценических версиях.
The article is devoted to one of the most famous regisseurs works of K.S. Stanislavsky, the play Mad day, or the marriage of Figaro by P.K. Beaumarchais Comedy, staged in 1927 in the Moscow Art theater with the music by R.M. Gliere. This statement is repeatedly described in the literature of the second half of the XXth century, but from different, not overlapping points of view. The aim of this study was to summarize the data to provide the most complete picture of the cultural circumstances associated with the genre of theatrical music as such and its development in the twentieth century. The participation of a major composer in the work of the great theater makes it possible to compare the score of Mad day with other theatrical works by Gliere, as well as with music for other productions of the Moscow Art theatre. It also covers a wider range of problems arising in connection with the existence of the dramaturgic primary source and the principal variation of its musical accompaniment in different stage versions.

A Modem for Receiving the Modulated Signals With Tikhonov Distribution Law
Authors: ВЕШКУРЦЕВ Ю.М. 
Published: September 2024

Повышение помехоустойчивости цифровых систем передачи данных актуально до настоящего времени. Однако известная теория модуляции амплитуды, фазы, частоты детерминированного колебания похоже исчерпала свои возможности, поскольку в улучшении помехоустойчивости систем нет заметного продвижения вперёд. Наверное, это не позволяют сделать устаревшие в теории постулаты и научные положения. Требуются новые рекомендации, позволяющие сделать скачок в повышении помехоустойчивости цифровых систем. Цель наших исследований найти новое направление, следуя которому можно будет на несколько порядков повысить помехоустойчивость цифровых систем передачи данных. Предлагаем заменить модель детерминированного колебания квазидетерминированным сигналом и перейти к модуляции характеристической функции. При формировании квазидетерминированного сигнала полезным будет использовать закон распределения Тихонова, рассмотренный в статистической радиотехнике. Построение модема для приёма сигналов с модулированной характеристической функцией обеспечивает заметное повышение помехоустойчивости цифровых систем. Исследования показали, что при работе модема в канале с шумами его помехоустойчивость, как минимум, на два порядка выше помехоустойчивости известных устройств.
Improving the noise immunity of digital data transmission systems is relevant to the present time. However, the known theory of modulation of amplitude, phase, frequency of deterministic oscillations seems to have exhausted its possibilities, since there is no noticeable progress in improving the noise immunity of systems. Probably, it is not possible to make outdated in theory postulates and scientific provisions. New recommendations are needed to make a leap in improving the noise immunity of digital systems. The purpose of our research is to find a new direction, following which it will be possible to increase noise immunity of digital data transmission systems by several orders of magnitude. We propose to replace the model of deterministic oscillation with a quasideterministic signal and proceed to the modulation of the characteristic function. When forming a quasideterministic signal, it will be useful to use the Tikhonov distribution law considered in statistical radio engineering. The construction of a modem for receiving signals with a modulated characteristic function provides a noticeable increase in noise immunity of digital systems. Studies have shown that when the modem is in the channel with noise, its noise immunity is at least two orders of magnitude higher than the noise immunity of known devices.

RESUMEN

La Región de las Américas ha experimentado históricamente desigualdades sociales enraizadas en el colonialismo, las cuales se reflejan y reproducen en el ámbito de la salud. La incursión de la pandemia de COVID-19 afectó a toda la Región, pero golpeó con mayor fuerza a los grupos socialmente más desaventajados, y agravó las inequidades en salud. Bajo la premisa que las pandemias no son fenómenos socialmente neutrales, en este informe especial se analizan los impactos desiguales de la pandemia desde distintas perspectivas –histórica, epidemiológica, política, social, económica, ambiental y poblacional. Se ofrecen aquí reflexiones críticas sobre las implicaciones negativas de las desigualdades para el bienestar, no solo de las poblaciones más afectadas, sino de la sociedad en su conjunto. Se concluye con recomendaciones estratégicas para progresar hacia la equidad en salud en el escenario pospandémico. Se destaca la importancia de avanzar en la madurez de los sistemas de información para el monitoreo de la equidad en salud, la resiliencia de los sistemas de salud, y la implementación de políticas y prácticas explícitas dirigidas a eliminar las inequidades en salud. Se espera que todo lo anterior allane el camino hacia la prosperidad y el desarrollo sostenible en la Región.
State of HIV costing in Latin America and the Caribbean: a systematic literature review
Authors: Cerecero-García Diego , Terris-Prestholt Fern , Macías-González Fernando , Bautista-Arredondo Sergio 
Published: September 2024

ABSTRACT

Objectives.

To summarize available data on unit costs for human immunodeficiency virus (HIV) testing, prevention, and care interventions in Latin America and the Caribbean.

Methods.

We conducted a systematic literature review of costing studies published between 2012 and 2024, and selected those reporting empirically measured costing data. The available data were categorized according to predefined intervention categories and compared by time and place. We also explored variations in unit costs by intervention type.

Results.

Of 1 746 studies identified, 22 met the inclusion criteria, which provided 103 unique unit cost estimates from nine countries. About 50% of the included studies were published between 2019 and 2021. Antiretroviral therapy services had the most cost data available (39% of unit costs), followed by inpatient care (27%) and HIV testing (24%). Considerable cost variations were observed both within and between interventions.

Conclusions.

Our analysis underscores the need for accurate and reliable cost data to support HIV budgeting and decision-making efforts. We identified several gaps in the availability of cost data and emphasize the importance of presenting results more effectively by incorporating key contextual variables. Given the challenges of shrinking budgets and sustainability risks, robust evidence is indispensable to inform priority setting and budget allocation for HIV services.
Singing One’s Life: Biopics of Edith Piaf and Dalida
Authors: Mazierska Ewa 
Published: September 2024

This article compares two films about French singing stars: La Môme (La Vie en Rose, 2007), directed by Olivier Dahan and Dalida (2016), directed by Lisa Azuelos, respectively about Edith Piaf and Dalida. It argues that Dahan in La Vie en Rose attempted to make a feminist biopic, which recognises that a famous woman can live mostly for her art or even equate her life with her art. This does not necessarily mean that such a woman, Piaf in this case, is unable to love passionately, but rather that there is no competition between her romantic and professional personas. Piaf’s talent for singing is also presented as a protection against external tragedies and as a source of meaning in her life. By contrast, Azuelos, in a more traditional fashion, plays up the contrast between the successful professional life of Dalida and her unhappy personal life, suggesting that if Dalida chose a different profession, she could be happier.
Biopics of Female Hollywood Stars Speak to #MeToo Era: The Case of Judy (2019) and Blonde (2022)
Authors: Díaz Elisenda 
Published: September 2024

This article analyzes two recent biopics, Judy (2019, Rupert Goold) and Blonde (2022, Andrew Dominik), which reimagine the icons from the Hollywood Golden Era, Judy Garland and Marilyn Monroe respectively, under the prism of the #MeToo movement. By examining the way in which these movies treat abusive experiences within the film industry, along with their placement in the public arena, this paper exposes how contemporary biopics dedicated to female movie stars face the consequences of #MeToo in Hollywood.
In terms of textual construction, both movies presumptively adopt a female perspective in portraying actresses’ experiences of exploitation –such as sexual harassment, eating disorders, substance abuse, and more– under a male-dominated Hollywood studio system. Meanwhile, directors’ articulated intentions, promotional campaigns, reviews, and film critiques seeking to convincingly place the films in the domain of public discussion around #MeToo.
Despite this ‘feminist’ assumption, this article will argue that these movies, while appearing to confront and re-address injustices in Hollywood through revisiting the mythical narratives of well-known female stars, fail to challenge the melodramatic victimization plot familiar in traditional biopics about women. In doing so, it will explore how they reinforce a representation of the female Hollywood star after #MeToo as a mentally troubled woman struggling to survive in an exploitative film industry.
Steve Jobs (2015): Art, The Man, The Machine
Authors: Archer Neil 
Published: September 2024

The second film in what one might call Aaron Sorkin’s ‘Asshole Diptych’ (following 2010’s The Social Network) Steve Jobs engages with Apple’s controversial founder: a man whose legacy, as Sorkin’s screenplay voices, had more to do with building beautiful machines than being a beautiful person. This article argues that Sorkin’s innovative biopic approaches its complex subject (both Jobs, and Silicon Valley) via the artifice and intricacy of its own screenplay form: the portrait of an imperfect man, as a perfect cinematic machine. Departing from classical biopic’s focus on the narrative of a ‘life’, Steve Jobs’ three-part structure - focusing on three public product releases - aligns with the structural expectations of the classical screenplay, as well as acknowledging its theatrical setting and influence: the idea of Jobs as a performance. In the script’s various progressions and parallelisms, this article shows, Steve Jobs offers a self-consciously aesthetic rendition of a life seemingly ‘fixed’. Recognising that art is more perfect than its subject, Sorkin’s film encapsulates and potentially obviates the contradictions at play in Jobs - not unlike the ‘beautiful products’ for which Jobs is himself recognised.
Case write-ups and reflective journal writing in early clinical years – Have these been “worthy” educational tools?
Authors: Sachdeva Pooja , Aw Derrick Chen-Wee 
Published: September 2024

Introduction: Case write-ups and reflective journals have been used as assessment tools of learning in clinical rotations in Yong Loo Lin school of medicine. It is timely to review the current process of conducting these assessments and effectiveness as an assessment tool. This study aims to understand faculty outlook towards these assessments.
Methods: This is a study that involves a survey-based questionnaire with both closed and open-ended questions, sent out to faculty marking the students’ assignments. This survey was anonymous & voluntary and was disseminated by administrative assistants. The purpose of this survey was to collect the feedback from faculty about current process with intentions of improving the effectiveness of these assessments. The suggestions for improvement were incorporated in the survey and faculty was invited to comment over these suggestions and provide further suggestions if any.
Results: Fifty-two responses from faculty were collected and analysed. Ninety percent of respondents thinks that this is an effective tool to assess and promote self-directed learning. Qualitative feedback was received about need of improvement in a) alignment of the submissions timings with rotation postings b) marking rubric to incorporate factors such as case complexity and weightage to different components of case write-ups, c) timely feedback to students, and d) follow up on action plans.
Conclusion: Case write-ups and reflective journals are still effective learning and assessment tools. They promote self-directed learning and clinical analysis in students. Feedback and action plans are the backbone of these assessments and optimal utilisation of these is recommended.

Authors: Lee Vivien , Jiang Jeffrey , Szücs Anna , Lee V Vien , Low Si Hui , Teo Faith , Valderas Jose M , Loh Victor 
Published: September 2024

Introduction: Globally, persons with disabilities (PWD) face structural and social barriers to inclusive healthcare. Medical schools, as crucibles of medical professional identity formation, have the responsibility to foster person-centredness toward all patients, including PWD, among her graduates. We co-designed with PWD a “Communications with Persons with Disabilities” workshop and evaluated its impact.
Methods: The workshop enlisted PWD as patient educators, occurred within the third-year undergraduate Family Medicine posting, and was designed to positively impact communications skills and attitudes toward PWD. Students (n=135) were surveyed pre- and post- workshop following a mixed-methods approach (demographic data, Attitude Towards Disabled Persons (ATDP)-O scale, feedback questions, and post-workshop free reflections). Descriptive analysis was used for demographic and feedback questions, and thematic analysis for reflections. Paired t-test was used to evaluate change in ATDP-O scores.
Results: There were 69 survey respondents (51.11%). Most students agreed that communications training with PWD could be strengthened in medical school, and that the workshop was relevant to their future medical career (n=68, 98.55%). Attitudes towards PWD significantly improved after the workshop (ATDP-O change: +9.29 points (12.7%), p <0.001). Student reflections included attitudes, such as the importance of seeing the person beyond the disability, and a call for action towards inclusivity and accessibility of care for PWD.
Conclusion: Students’ attitudes were positively affected by involving PWD in the curriculum. Further research is needed for assessing the impact of how a longitudinal PWD curriculum could affect medical trainees and improve social inclusiveness in healthcare practice.

When studying the DNA polymorphism of ancient seeds from archaeological excavations, and comparing them with modern ones, it is possible, depending on the evolutionary significance/neutrality of the identified differences, to either find traces of adaptation of genotypes used in ancient times to unfavorable environmental conditions, or to clarify the origin of the samples, establishing additional evidence of trade and economic ties between different regions in different eras. The purpose of this work was to study the DNA polymorphism by comparing the 12th-century barley seeds from the Usvyaty settlement of the Pskov Region and VIR collection accessions of different geographical origin using theCHIandELF3gene fragments sequencing data. Of the 18 polymorphic SNP loci identified in the studied genes during the analysis of the barley samples under study, seven SNPs were from the regions amenable for resequencing in ancient DNA samples. The identified allelic changes in those seven SNP loci were neutral and did not lead to amino acid substitutions, therefore they can be used for a comparative analysis of the sample origin. The haplotype revealed in ancient barley based on the seven studied SNPs did not completely coincide with any of the studied accessions from the VIR collection. At the same time, rare alleles showed similarities with a Belarusian cultivar ‘Krinichny’, and the frequently occurring ones with several accessions ofH. vulgare L. of different origin (Sweden, Denmark, Armenia), as well as withH. spontaneum(K. Koch) Thell.

The authors dedicate this work to the memory of the famous researcher of the flora of the Southern Urals, Professor, Doctor of Biological Sciences Evgeniy Vasilyevich Kucherov, whose 100th birthday anniversary was celebrated on May 10, 2024.	The species Androsace kuczerovii Knjasev (family Primulaceae) – endemic to the Southern Urals – was described in 1998 from the territory of the Republic of Bashkortostan (RB) by the famous botanist from Yekaterinburg M.S. Knyazev [Knyazev, 1998]. The species is included in the Red Book of the Republic of Bashkortostan, 3rd edition [2021] with regional protection status: 1) rarity status category: 1 – endangered species; 2) endangered status category: critically endangered (CR); 3) conservation status: I priority (immediate adoption of comprehensive measures is required, including the development and implementation of a strategy for the conservation of this species and (or) a program for their restoration (reintroduction) in the Southern Urals). In the Republic of Bashkortostan, three localities of the species are known on the eastern slope of the Southern Urals – in the Abzelilovsky (Ulugurtau ridge near the village of Makhmutovo, Mount Turpai near the village Ishkulovo) and Baymaksky (Irendyk ridge in the vicinity of the village of Kuseevo) regions. The features of ecology and biology, the size and condition of the population on the ridge Ulugurtau, limiting factors, and the measures taken and necessary to protect this species are considered.
