G. Cziffra in Beethovenian context of the twentieth century
Authors: Yelyzaveta Chorna
Published: May 2022

The celebration of L.VanBeethoven’s 250th anniversary stimulated an already sustained interest in his creative heritage. Musicological thought has not stayed away from the figure of the outstanding Viennese classicist. Therefore, the question of the interpretation of his works again becomes relevant in this context. The name of György Cziffra, the famous twentieth-century Hungarian pianist, is closely linked in the history of European pianism with the element of virtuosity, at first, with F. List’s music presentation. The difference opinions about Cziffra’s interpretations of other composers and Beethoven among them, as well as unexplored peculiarities of the pianist’s interpretation of Beethoven’s music actualize the choice of our theme and determine the scientific novelty of the research results. The purpose of the article is to reveal the parameters of G. Cziffra’s individual performing style in historical context of the twentieth-century Beethovenian. For the first time in Ukrainian musicology, the creative principles of the Hungarian pianist as an interpreter of Beethoven’s works on the example of the composer’s “32 Variations” in C minor are analyzed; some parallels between the performance principles of Hungarian master and the composer himself are outlined. The methods of a stylistic analysis in projection to the performance art, as well as on a comparative approach, which allows to reveal the uniqueness of Cziffra’s interpretation of Beethoven’s music text, were applied. Analyzing the Hungarian pianist’s performance of the “32Variations” cycle, we heard a new interpretation of Beethoven’s ‘heroic’ character, but we did not observe any emphasis on virtuosity for the sake of itself, but rather a musical intellectuality took place. It is the subtle nuances, strokes, tempo, character and the rich palette of articulations that determine the Hungarian pianist’s performance style. Summarizing, we can observe, on the one hand, Cziffra’s own ‘romantic’ individualized interpretation of Beethoven’s music in the 20th century, and, on the other hand, some parallels, although less evident, with the specific features of Beethoven’s own performance style.
Lester Young’s performance poetics and performance style: the experience of analysis
Authors: Zhang Qi
Published: May 2022

The research focuses on the system of performance resources of expression of a jazz musician, which received the title of “performance poetics” and “performance style”. L. Young’s creative work has repeatedly been the subject of research, in particularly, in publications by L. Porter (1981) and D. Daniels (1985; 2002; 2005), one of the outstanding biographers of the jazz master. D. Gelly (2007) includes L. Young into the pantheon of the most influential jazz performers reflecting the components of his performance style. J. P. De Lucia (2017) calls L. Young a key figure at the beginning of swing era. The scientific novelty of our study lies in the development of aspects of the analysis of the performance poetics of jazz musicians basing on L. Young’s creativity. The purpose of the article is to identify the parameters of Lester Young’s performance poetics. As the research methods the communicative-interpretative, systematic, stylistic approaches and the performance analysis are used. The analysis of performance poetics is based on the Kharkiv I. P. Kotlyarevsky National University of Arts musicologists’ developments: by L. Shapovalova (2007) devoted to the “performance time-space” concept and Yu.Nikolaievska’s monograph (2020) on the performance interpretology. The results of the study are based on the analysis of L. Young’s compositions the “Squabblin” and the “Blue Devils Blues”; on his work as a soloist-improviser in King Oliver’s orchestra and in the band “Blue Devils”. Conclusion supports the idea of performance poetics as an artistic system, which is a “reflection of the musician’s interpretative thinking” (Nikolaievska, 2020) in such parameters as melody, metro-rhythm, tonality, harmony, texture and the corresponding “toponyms” – articulation, tempo-rhythm, dynamic score, and “toponymics” as performance reproduction of texture. It is articulated оn such positions as unique timbre and sound production (specific position of the mouthpiece), expansion of harmonious thinking (melodic use of fourths and fifths, “horizontal” concept of phrasing). L. Young’s unique performing style is based on the principles of “stretched sound”, “horizontal” concept of improvisation, intense vibrato and the formation of a performance as a reflection act.

Published: May 2022

A procedure for the synthesis of borosiloxane compounds by the reaction of polydimethylsiloxane with boric acid upon heating in a cylindrical reaction vessel is presented. The mixing of the reaction components in the considered method occurs spontaneously due to the sublimation of boric acid vapor and its movement in a natural way from the lower part of the reaction vessel to the upper part through the volume of polydimethylsiloxane. The technique makes it possible to synthesize borosiloxane compounds without the use of special equipment, increased energy consumption, and chemical solvents.

The conflict between the fundamental rights for the application of the right to be forgotten has been clarified in specific cases, when taking into account the rights to privacy, honor, intimacy, image, privacy, on the one hand, and the other, the right to information, the free expression of thought, the research being carried out through the jurisprudential, through the inductive and documentary scientific method.
El juego literario y sus desdoblamientos
Authors: Trouvé Alain
Published: May 2022

Este artículo propone pensar la escritura literaria como un juego a partir de una reflexión crítica sobre ciertas nociones o conceptos asociados, primordialmente, los de escritura y lectura. Asimismo, revisa la ampliación conceptual que supusieron la noción de texto en la década de 1960, la ya clásica categoría de intertexto, así como la más novedosa idea de palabra o la recientemente redescubierta de tras-texto, y finalmente la de ficción, en función de analizar cómo estas interactúan para darle sustancia al juego de la escritura literaria. ¿Cómo pensar el acto desdoblado de escribir y de leer, constitutivo del juego literario, en su complejidad y en su relación con el tiempo? El énfasis puesto en tal o cual parámetro de la relación conduce a considerar sucesiva o simultáneamente una teoría de la lectura como juego, promovida al rango de lectura literaria, una teoría lúdica de la escritura-lectura y una oscilación lúdica de la propia teoría.

Sobre el sentido de empaízō (y el juego invencible de Afrodita) en el tercer canto coral de Antígona de Sófocles (vv. 781-800)
Authors: Hernández Aparicio Santiago
Published: May 2022

El presente artículo explora el sentido que asume el verbo XXXX, compuesto de παίζω (“jugar”), en el contexto grave y mortífero de la escena trágica y, en particular, cuando quienes juegan son dioses como Afrodita y Eros. Para ello, seleccionamos el tercer estásimo de Antígona de Sófocles (vv. 781-800), en cuyos últimos versos se les adjudica a estas divinidades el acto de jugar que, hipotetizamos, habilita una lectura lúdica de todos sus actos en la oda. Además, sostenemos que una consideración adecuada de la esfera de acción de estas divinidades habilita una lectura lo suficientemente amplia del estásimo como para considerarlo un tablero que abarca a todas las piezas del conflicto trágico.

Authors: Chaudhry Muhammad Ali , Cukurova Mutlu , Luckin Rose
Published: May 2022

Numerous AI ethics checklists and frameworks have been proposed focusing on different dimensions of ethical AI such as fairness, explainability, and safety. Yet, no such work has been done on developing transparent AI systems for real-world educational scenarios. This paper presents a Transparency Index framework that has been iteratively co-designed with different stakeholders of AI in education, including educators, ed-tech experts, and AI practitioners. We map the requirements of transparency for different categories of stakeholders of AI in education and demonstrate that transparency considerations are embedded in the entire AI development process from the data collection stage until the AI system is deployed in the real world and iteratively improved. We also demonstrate how transparency enables the implementation of other ethical AI dimensions in Education like interpretability, accountability, and safety. In conclusion, we discuss the directions for future research in this newly emerging field. The main contribution of this study is that it highlights the importance of transparency in developing AI-powered educational technologies and proposes an index framework for its conceptualization for AI in education.

Patient Behavior: An Extensive Review
Authors: Mohiuddin Abdul Kader
Published: May 2022

The most frequent causes of death in the United States and globally are chronic diseases, including heart disease, cancer, lung diseases, and diabetes. Behavioral factors, particularly tobacco use, diet and activity patterns, alcohol consumption, sexual behavior, and avoidable injuries are among the most prominent contributors to mortality. Projections of the global burden of disease for the next two decades include increases in noncommunicable diseases, high rates of tobacco-related deaths, and a dramatic rise in deaths from HIV/AIDS. Worldwide, the major causes of death by 2030 are expected to be HIV/AIDS, depressive disorders, and heart disease. At the same time, in many parts of the world, infectious diseases continue to pose grim threats, especially for the very young, the old, and those with compromised immune systems. Malaria, diarrheal diseases, and other infectious diseases, in addition to AIDS, are major health threats to the poorest people around the world. And, like chronic diseases, their trajectory may be influenced by the application of effective health behavior interventions. Substantial suffering, premature mortality, and medical costs can be avoided by positive changes in behavior at multiple levels. Most recently, there has been a renewed focus on public health infrastructure to plan for emergencies, including both human-made and natural disasters. During the past twenty years, there has been a dramatic increase in public, private, and professional interest in preventing disability and death through changes in lifestyle and participation in screening programs. Much of this interest in disease prevention and early detection has been stimulated by the epidemiological transition from infectious to chronic diseases as leading causes of death, the aging of the population, rapidly escalating health care costs, and data linking individual behaviors to increased risk of morbidity and mortality.

Published: May 2022

Cryptic tonsils are the manifestation of repeated inflammation of the tonsils. In particular, the term is used to indicate the occupation of the space of the crypts present on the surface of the tonsillar glands, by infectious debris, deposits of calcific material or food residues. Cryptic tonsils are associated with the appearance of whitish plaques (tonsillolith) and bad breath (halitosis), ear pain, sore throat, hypertrophic tonsils and swallowing problems. A 25-year-old patient comes to the practice for oral hygiene when we notice his cryptic tonsils that cause him to form tonsilloliths and halitosis, creating embarrassment for the patient and limits in interpersonal relationships.

The optimal management in these patients may contribute in decrease hospital mortality.
Export Taxes and Trade Pattern: Case from the Indonesian Mineral Industry
Authors: Laksana Made Putra Adhi
Published: May 2022

The Indonesian government adopted mineral export taxes by imposing a high tariff on raw materials while waiving tariffs on processed products. Tariffs decreased following the progress of refinery plant construction. Based on the fixed effects panel regression at the commodity-country-pair level, this study finds that the export taxes system negatively reduces raw material export while increasing processed mineral export. Tariff stratification on mineral commodities distorts trade patterns, affecting business orientation in upstream and downstream sectors. Furthermore, tier tariff significantly elevates the export quantity of downstream products compared to flat export taxes, directly proportional to export value. Export contraction of raw materials resulted from tier tariff slightly lower than the flat type but with a higher exports performance of processed products. The shifting phenomena to the value-added industry indicate an effort for export taxes evasion. This finding is reinforced by the massive investment inflow in the mineral processing sector. Meanwhile, the exporter manufacturing industry positively correlates with the export performance of processed products and a negative direction with raw material, which aligns with the main finding.

Unjustified: The Practical Irrelevance of the Justification/Excuse Distinction
Authors: Chin Gabriel
Published: May 2022

In recent decades, the distinction between justification and excuse defenses has been a favorite topic of theorists of philosophy and criminal law. Notwithstanding the impressive intellectual efforts devoted to the task, no single scholar or viewpoint appears to be on the verge of generating practical consensus about the concepts of justification and excuse, categorization of the defenses, or categorization of difficult individual cases. This Essay suggests that none of these goals can be usefully advanced through the justification/excuse distinction.

Bu tədqiqat qaz nəqli sistemlərinin modelləşdirilməsi məsələsinə həsr edilmişdir. Müasir qaz şəbəkələri yaşayış məntəqələrini və bütün rayonları təbii qaz mənbələri ilə birləşdirir. Bu cür sistemlər hazırda olduqca mürəkkəbdir və onların modelləşdirilməsi böyük hesablama xərcləri tələb edir. Təqdim olunan işin məqsədi məlumatların işlənməsi vaxtını azaltmaq üçün istismar olunan qaz kəmərlərinin, habelə rabitə qovşaqlarının riyazi modelinə daxil edilmiş tənlik sistemlərinin həllinin səmərəliliyini artırmaqdır. İşdə əsas diqqət digər modelin tənliklərini həll etmək üçün bir modelin tənliklərindən istifadə edərək qaz kəmərlərinin və qarşılıqlı əlaqə qovşaqlarının riyazi modellərinin birləşdirilməsinə yönəldilir. Müasir təcrübədə qaz kəmərlərinin sənaye istismarı modelləşdirmədə təbii qaz axını çox vaxt biristiqamətli izotermik axın kimi qəbul edilir. Təqdim olunan işdə qazın nəqli prosesinin dinamikasını müəyyən edən qismən törəmələr sistemindən alınmış iki sadələşdirilmiş model verilmişdir. Bu modellərə boru kəməri oxunun üfüqə meyl parametri daxildir ki, bu da modelləşdirmədə çox vaxt laqeyd qalır. Hazırlanan metodologiyanın bu özəlliyi həm də daha dəqiq simulyasiya nəticələri əldə etməyə imkan verə bilər.

The article analyzes the elimination of the causes of absorption of drilling mud. Drilling mud - In geotechnical engineering, drilling mud is used to help drill boreholes in the ground. Drilling fluid is often used in oil and natural gas, as well as in very simple boreholes, such as artesian wells in exploration wells. Drilling fluid is often referred to as clay solution. There are three main types of drilling fluid: water-based drilling mud (which can be dispersed and non-dispersed), non-aqueous muds commonly referred to as oil-based clay muds, and gas-forming drilling muds that can be used in a wide range of gases. The main function of the drilling mud is to prevent pressure on the formation fluids entering the wellbore, to keep the drilling ax clean and cool during drilling, and to remove drilling rocks. The drilling fluid used for special work selected to avoid damage to the formation and to limit corrosion. In order to avoid complications and accidents in any well being drilled, it is necessary to work to ensure that the quality parameters of the drilling mud in accordance with the intervals are in accordance with the parameters specified in the mandatory geological specifications. Otherwise, the possibility of complications and accidents is very real, and in this case, primarily the drilling master, as well as the drilling crew is responsible.
Keywords: drilling mud, solution absorption, causes of absorption, clay solution, drilling of wells, complications.
SELECTION OF THE OPTIMAL METHOD OF OPERATION FOR GAS-LIFT WELLS OPERATING IN OFFSHORE CONDITIONS AND EVALUATION OF ITS EFFICIENCY
Authors: Agashirin Shirinov Agashirin Shirinov , Tofig Samadov Tofig Samadov
Published: May 2022

As the field is developed, the operating conditions of the wells deteriorate; the product is hydrated, the hydrostatic pressure of the fluid column increases, a high-viscosity emulsion is formed, the pressure loss due to friction in the wellbore and discharge line increases, which increases the wellbore and wellhead pressures, the effective gas factor decreases, and the required specific gas consumption increase. When gas is supplied to the pipe space through compressors, the liquid level decreases and increases in the pump-compressor pipes. When the liquid level reaches the shoe as a result of gas supply, the gas-liquid mixture enters the pump-compressor pipes and mixes with the liquid. As a result, the density of such a gas-liquid mixture is less than the density of the liquid entering the formation, and the level of the liquid in the pump-compressor pipes rises. The more gas is supplied, the lower the density of the mixture, and the higher the mixture. In the case of continuous supply of compressed gas to the well, the gas-liquid mixture rises to the mouth of the well. After the gas-gas mixture is removed from the well, a new amount of liquid enters the well from the formation. Production of a gas lift well - the amount of gas injected, the depth of unloading of the pump-compressor pipes (submersible depth), the diameter of the lifting pipes, the viscosity of the liquid, etc. depends on factors..
Keywords: Gas-lift, optimal operating mode, well, well pressure, compressor, pipe
ESTUDOS DE AULA COM PROFESSORES QUE ENSINAM MATEMÁTICA NOS PRIMEIROS ANOS EM PORTUGAL
Authors: Fonseca Gorete , Ponte João Pedro da
Published: May 2022

O estudo de aula é um processo de formação que ocorre em um contexto colaborativo que leva os participantes (professores ou futuros professores) a refletirem sobre a prática profissional e a realizarem novas aprendizagens. Este texto começa por fazer uma breve análise dos estudos de aula como processo cultural, mostrando a necessidade da sua adaptação ao contexto local. Tendo por base uma experiência realizada em Portugal com professores que lecionam o 2.º ano de escolaridade, apresentam-se as possibilidades formativas dos estudos de aula no que se refere às aprendizagens profissionais dos professores relativas à prática letiva, com enfoque na seleção de tarefas, na análise do raciocínio dos alunos e na condução do trabalho em sala de aula. Procuramos, ainda, mostrar que os estudos de aula podem dar um significativo contributo para o desenvolvimento do trabalho colaborativo entre professores e para a valorização da reflexão sobre a prática.

Authors: Bahn Jacob , Macedo Aluska , Winsløw Carl , Rasmussen Klaus
Published: May 2022

Lesson study em Matemática tem uma história relativamente curta na Dinamarca (cerca de 15 anos) e ainda não é amplamente implementada. O que pode ser aprendido com as primeiras experiências neste pequeno país relativamente privilegiado? Descreve-se a situação em três contextos institucionais principais, nomeadamente o ensino básico (anos iniciais e finais do ensino fundamental), o ensino secundário (ensino médio) e a formação de professores em faculdades, procurando responder às seguintes questões: o que motivou as iniciativas de introdução do Lesson Study para os professores de matemática? Que obstáculos e resultados são vivenciados? A seção final resume as respostas à essas questões, com foco no que pode ser de interesse em contextos semelhantes fora da Dinamarca.

W artykule omówiono wyniki badań przeprowadzonych w celu określenia preferencji pracowników w zakresie kanałów komunikacji BHP oraz ocenę przydatności informacji przekazywanych klasycznymi i elektronicznymi kanałami komunikacji dla poprawy bezpieczeństwa i zdrowia w pracy przed pandemią COVID-19 i w jej trakcie. Badania przeprowadzono metodą kwestionariuszową w 2016 roku i w 2021 roku. Wyniki badań dla okresu sprzed i w trakcie pandemii są porównywalne: większość pracowników skłania się ku klasycznym kanałom komunikacji, takim jak tradycyjne szkolenia i spotkania z kierownictwem oraz tradycyjne rozmowy z kolegami. Informacje BHP uznawane za przydatne do bezpiecznego wykonywania pracy są przekazywane głównie za pomocą klasycznych kanałów komunikacji. Najniżej z punktu widzenia przydatności oceniono media społecznościowe. Badania wskazują, że kanały elektroniczne mogą wspierać klasyczne kanały wykorzystywane w komunikacji BHP, ale nie mogą ich zastępować.

Przyjęto, iż port lotniczy jest podmiotem gospodarczym, który w warunkach silnej konkurencji musi aktywnie wykorzystywać dostępne narzędzia marketingowe dla osiągania celów rynkowych i dostosowywać je do zróżnicowanych potrzeb i preferencji klientów indywidualnych i instytucjonalnych. Z uwagi na bogatą paletę możliwości serwis społecznościowy Facebook został wskazany jako popularne i skuteczne narzędzie marketingowe. Dokonana została ocena aktywności portów lotniczych w przedmiotowym serwisie w postaci zaprezentowania wyników analizy porównawczej danych z bieżącej działalności z danymi z 2014 roku. Wskazano ogólną klasyfikację celów publikacji treści przez porty lotnicze za pośrednictwem stron firmowych na Facebooku. Na przykładzie Lotniska Chopina w Warszawie zdefiniowano sposób prowadzenia komunikacji z aktualnymi i potencjalnymi klientami w serwisie Facebook w sytuacji IV fali pandemii COVID-19. Procedura badawcza została przeprowadzona w sytuacji wprowadzenia ograniczeń w czasie jej realizacji, co zdeterminowało potrzebę dookreślenia dalszych kierunków badań dla zapewnienia szerszej perspektywy oceny i większej wiarygodności osiągniętych rezultatów badawczych.
Zur antiken Umarbeitung und Wiederverwendung von Grabstelen in Kleinasien und in den griechischen Inseln
Authors: CHRİSTOF Eva
Published: May 2022

Hellenistic and Roman grave steles in Asia Minor were usually produced and put in place for a unique, specific purpose and intended for eternal display at the tomb. We can see, however, that even long before the Late Antique period when the recycling of spolia became frequent, these grave steles were reused and repurposed as grave steles. The main procedure was to simply add a new inscription or to erase the old inscription in order to overwrite it with a new one; minor details of relief decoration might be changed or it even might be left as it was. In this article, I explore and describe this multifaceted phenomenon, which can be traced by examining the actual state of the monuments to detect the presence of one or more inscriptions, erasures and incongruities between pictures and text, as well as the chiselled-off or lowered parts and remodelled relief decorations. This contribution sets this phenomenon within a larger context between the two poles, one of which is the practical and economic object recycling, a familiar procedure that several materials underwent in antiquity, and the second of which is the predilection for antiquities and the re-use of old and valuable things in meaningful ways. The main procedures used to rework grave steles are illustrated by presenting some examples from across Anatolia; this selection remains, of course, far from exhaustive. If we consider the repurposing of funerary steles and other archaeological objects by applying the theoretical approaches of object biography and life cycle-management, i.e. taking into account all single phases of the use of a specific object, we will uncover new ways to understand those Anatolian grave steles hitherto believed anomalous. These approaches enable us to accept, handle, and integrate the different phases of perceiving and reconstructing ancient realities.

The article introduces a hitherto unpublished small fragment of a bronze tablet in the Collec-tion Fedor K., Budapest. It is inscribed with the copy of an imperial letter (exemplum sacrarum litterarum) presumably from the Black Sea region. Although neither the name of the emperor nor a date is preserved, epigraphic elements point to a dating in the 3rd-4th century.
