Works for piano by Cornelius Cardew in the light of creative searches of the composer
Authors: Копосова И.В.
Published: September 2024

Творчество Корнелиуса Кардью (1936–1981) – одного из ведущих представителей новейшей британской музыки – имеет самобытную стилевую эволюцию. Свой путь композитор начал как убежденный приверженец второго авангарда, а завершил сочинениями, которые были рассчитаны на широкую аудиторию и базировались на социалистических идеях. В статье поиски Кардью рассмотрены на примере фортепианных сочинений, созданных с конца 1950-х до начала 1980-х гг. Они предназначены как для солирующего инструмента, так и для дуэта фортепиано. Анализ опусов разных лет позволил раскрыть круг художественных идей, волновавших британского автора в разные годы, обсудить особенности их реализации, а также сделать общие заключения о стилистике Корнелиуса Кардью.

Cornelius Cardew (1936–1981) – one of the leading representatives of the latest British music – has a distinctive style evolution. He began his career as an adherent of the second avant-garde and finished his works, which were intended for a wide audience and were inspired by socialist ideas. The article deals with the search for Cardew on the example of piano compositions (for a solo instrument and for a piano duet), which were created from the late 1950s to the early 1980s. The analysis of these works allowed to reveal the range of creative ideas that worried the British author in different years, to discuss the features of the implementation of these ideas, as well as to make general conclusions about the style of Cardew.

Published: September 2024

Статья посвящена особенностям структуры и музыкального языка в Сонатах для скрипки и фортепиано видного армянского композитора Вардана Аджемяна, который в своем творчестве синтезирует современные тенденции с национальными элементами. Статья содержит важные аспекты творческого пути композитора, краткий экскурс в историю армянской скрипичной сонаты (ключевые этапы развития жанра, характерные особенности), которая, вобрав в себя все богатство стилей, форм, приемов, выработанных в европейской музыке, развивалась собственным путем. Основное содержание исследования составляет подробный методический анализ Сонаты-поэмы, в которой совмещаются сонатная одночастность и сонатная цикличность, и Сонаты для скрипки и фортепиано № 2, состоящей из трех частей, в которой изменена традиционная темповая последовательность: две медленные части предваряют скерцозный финал. Органическое сочетание классических, современных и национальных элементов, стилей и тенденций (импрессионизма, додекафонии и народной и духовной музыки) делают эти произведения необычайно интересными как для исполнителей, так и для слушателей.

The article is dedicated to the distinguishing features of the structure and musical language in the sonatas for violin and piano of the notable Armenian composer Vartan Adjemian who synthesizes contemporary trends with national elements in his work. The article contains important aspects of the composer’s creative path, a brief overview of the history of the Armenian violin sonatas (key stages of the development of the genre, its characteristics) which having embraced the entire wealth of styles, forms and techniques crafted in the European music, chose its own way of development. The main part of the study covers a detailed methodological analysis of the Sonata-Poem which combines the single-movement nature and cyclicism of the sonata, as well as analysis of Sonata № 2 for violin and piano comprising three movements, in which the traditional sequence of tempo is changed: the scherzo finale is preceded by two slow movements. Organic combination of classical, modern and national elements, styles and trends (impressionism, dodecaphony and folk and spiritual music) render these pieces extraordinarily interesting both for the performers and the listeners.
Latin American popular music and the problem of cultural identity
Authors: Доценко В.Р.
Published: September 2024

Латиноамериканская популярная музыка получила в современную эпоху мировое распространение. Многочисленные международные фестивали, конкурсы, выступления ансамблей и отдельных исполнителей стали неотъемлемой составляющей массовой культуры, в связи с чем возникла необходимость в выявлении природы этого многомерного явления, выступающего в постоянно эволюционирующем триединстве американских, европейских и африканских элементов. Технологическая революция, сопровождающая глобализацию, способствует возникновению гибридных жанров, формирующихся в результате проникновения в традиционные образцы элементов джаза и разновидностей поп-музыки. Массовое коммерческое производство стимулирует гомогенизацию – стилистическое обезличивание музыкальной продукции. Данное явление порождает опасения, что локальные и региональные культурные традиции будут подавлены вследствие интернационализации, а новая униформистская глобальная культура станет преобладающей. Вместе с тем получает развитие и обратная тенденция к гетерогенности, самоутверждению местных, локальных культур, мотивируемая потребностью в сохранении этнических отличий. Проблему баланса между гомогенизацией и гетерогенизацией можно считать стержневой в процессе эволюции современной популярной музыки. В данном контексте нами предпринят анализ гибридных жанров индейской музыки в Мексике, Перу и карибо-американской сальсой, как примерами эволюции культурной идентичности в глобализирующемся мире.

Latin American popular music has received in the modern era of world distribution. Numerous international festivals, competitions, performances of ensembles and individual performers have become an integral part of mass culture. In this regard, it became necessary to identify the nature of this multidimensional phenomenon, which is a constantly evolving Trinity of American, European and African elements. The technological revolution accompanying globalization has contributed to the emergence of hybrid genres emerging as a result of the penetration of elements of jazz and varieties of pop music into traditional patterns. Mass commercial production stimulated homogenization – stylistic depersonalization of musical production. This phenomenon has given rise to fears that local and regional cultural traditions will be suppressed due to the internationalization and a new uniform global culture will become predominant. At the same time, the reverse trend towards heterogeneity and self-affirmation of local cultures, motivated by the need to preserve ethnic differences, was also developed. The problem of the balance between homogenization and heterogenization can be considered pivotal in the evolution of modern popular music. In this context, we have undertaken an analysis of hybrid genres of Indian music in Mexico, Peru and the Caribbean-American salsa as examples of the evolution of cultural identity in a globalizing world.

Authors: Скорбященская О.А.
Published: September 2024

Переписка Роберта Шумана и Адольфа Гензельта является ярким свидетельством творческого диалога двух коллег-композиторов, живших в эпоху немецкого романтизма. На примере двух писем Роберта Шумана, хранящихся в Отделе рукописей РНБ Санкт-Петербурга, автор статьи делает попытку впервые в современном отечественном музыковедении создать своего рода «графологический портрет» великого немецкого романтика и делает вывод о глубоком своеобразии шумановской личности, отраженном в его почерке, а также анализирует роль Шумана в творческом развитии Адольфа Гензельта.

The correspondence between Robert Schumann and Adolf Henselt is a clear indication of the creative dialogue between two fellow composers living in the era of German romanticism. Using the example of two letters by Robert Schumann, stored in the Manuscript Department of the NLR of St. Petersburg, the author makes an attempt, for the first time in modern musicology, to create a kind of "graphological portrait" of the great German romantics and concludes that Schuman’s personality is deeply peculiar and also analyzes the role of Schumann in the creative development of Adolf Henselt.

РостовнаДону город с богатой опереточной традицией. Без малого 70 лет (1931 1999) существовал театр музыкальной комедии, считавшийся одним из лучших в стране. Его правопреемник Ростовский музыкальный театр, на сцене которого идут оперы и балеты, но и оперетта занимает в репертуаре достойное место. Однако первое знакомство города с этим жанром состоялось ещё в 1869 году Ростов в этом отношении опередил едва ли не все другие города русской провинции. Была создана постоянная труппа, репертуар которой составляли преимущественно оперетты. События тех лет, личность и деятельность Григория Вальяно антрепренёра, режиссёра, актёра, переводчика текстов всё это впервые в отечественном музыковедении оказывается в центре пристального внимания и становится предметом исследования автора статьи.

В статье рассматриваются скрипичные произведения композиторов ХХ века, в которых инструмент трактуется с позиции исполнительских особенностей и текстовой выразительности, а его звуковой облик предстает современным, необычным, новым. Автор не просто расширяет спектр выразительных возможностей скрипки, но представляет ее поиному в условиях авангардных техник письма от неомодальности до полистилистики. особое внимание уделяется тому, какие новые тембровые краски находят авангардные композиторы и насколько широким оказывается звукокрасочный потенциал скрипки. Автор, казалось бы, доходит до использования штрихов, делающих звучание инструмента неузнаваемым, однако большинство, даже самых смелых экспериментаторов ХХ века все же не лишает скрипку ее человеческого звукового облика того, что дан ей от природы и что так привлекает композиторов и слушателей во все времена.

The article discusses the violin works of composers of the twentieth century, in which the tool is interpreted from the perspective of performance features and textual expression, and its sound shape appears modern, unusual, new. The author broadens the range of expressive possibilities of the violin, but is it different in terms of avantgarde techniques of letter from neomodernist to polystylism. special attention is paid to what the new tone of paint find avantgarde composers and how wide is spookocracy potential of the violin. The author seemingly comes to using strokes that make the sound of the instrument unrecognizable, but most, even the most daring experimenters of the twentieth century, still does not deprive the violin of its human sound image of what is given to it by nature and that it attracted composers and listeners at all times.

Статья посвящена вопросам построения измерительных устройств на базе феррозондовых преобразователей. Рассматривается возможность использования в качестве полезного сигнала, несущего информацию о величине напряженности измеряемого магнитного поля, частоты генератора, выполненного на логических элементах и запитывающего обмотку возбуждения феррозонда. В таком генераторе обмотка возбуждения становится фактически элементом самого генератора. Поэтому измеряемое магнитное поле через обмотку возбуждения оказывает влияние на работу генератора, что приводит к изменению его частоты. В статье показано, что величина изменения частоты оказывается достаточной для того, чтобы говорить о возможности нестандартного частотометрического способа построения устройств на базе феррозондов. Показано, что использование частоты в качестве полезного сигнала имеет свои преимущества. Экспериментально установлено, что феррозонд эффективно работает не только на конкретной частоте, указанной в его паспортных данных, но и в достаточно широких пределах. Показано, что изменения частоты укладываются в диапазон, в котором феррозонд работает наиболее эффективно. В статье приводится оригинальная схема генератора для запитки обмотки возбуждения феррозонда и реализующая частотометрический способ построения устройств измерения напряженности магнитного поля.

The article is devoted to the construction of measuring devices based on flux-gate transducers. The possibility of using as a useful signal, carrying information about the magnitude of the measured magnetic field, the frequency of the generator, performed on the logic elements and powering the excitation winding of the fluxgate, is considered. In such a generator, the field winding becomes in fact an element of the generator itself. Therefore, the measured magnetic field through the excitation winding affects the operation of the generator, which leads to a change in its frequency. The article shows that the magnitude of the frequency change is sufficient to talk about the possibility of a non-standard frequency measurement method for constructing devices based on flux-probes. It is shown that the use of frequency as a useful signal has its advantages. It has been established experimentally that the flux-probe effectively works not only at a specific frequency specified in its passport data, but also within fairly wide limits. It is shown that the frequency changes fall within the range in which the flux probe operates most efficiently. The article provides an original generator circuit for powering the excitation winding of a fluxgate and implementing a frequencymeasurement method for constructing devices for measuring magnetic field strength.

С использованием новых знаний реконструирован модем цифровых систем разного назначения с амплитудной манипуляцией. Предложено рассматривать характеристическую функцию квазидетерминированного сигнала, которая одновременно с амплитудой модулирована в противофазе телеграфным сообщением. Построен демодулятор для приема команд управления с использованием оценок действительной и мнимой частей характеристической функции. Повышена на два порядка помехоустойчивость цифровой системы с амплитудной манипуляцией путем включения в её состав нового демодулятора, работающего в диапазоне отношений сигнал/шум 20 дБ.

With the use of new knowledge, the modem of digital systems for different purposes with amplitude manipulation was reconstructed. It is proposed to consider the characteristic function of a guasi – deterministic signal, which is modulated simultaneously with the amplitude in the antiphase by a telegraph message. A demodulator was built for receiving control commands using estimates of the real and imaginary parts of the characteristic function. The noise immunity of a digital system with amplitude manipulation is increased by two orders of magnitude by incorporating a new demodulators operating in the signal – to – noise ratio range of 20 dB.

Published: September 2024

There is a perpetual need for efficient and mild methods to integrate deuterium atoms into carbon frameworks through late-stage modifications. We have developed a simple and highly effective synthetic route for hydrogen isotope exchange (HIE) in aromatic compounds under ambient conditions. This method utilizes catalytic amounts of hexafluorophosphate (PF6−) in deuterated 1,1,1,3,3,3-hexafluoroisopropanol (HFIP-d1) and D2O. Phenols, anilines, anisoles, and heterocyclic compounds were converted with high yields and excellent deuterium incorporations, which allows for the synthesis of a wide range of deuterated aromatic compounds. Spectroscopic and theoretical studies show that an interactive H-bonding network triggered by HFIP-d1 activates the typically inert P-F bond in PF6 for D2O addition. The thus in-situ formed DPO2F2 triggers then HIE, offering a new way to deuterated building blocks, drugs, and natural-product derivatives with high deuterium incorporation via the activation of strong bonds.
An Experimental and Modeling Study of CaCO3 Nucleation and Inhibition Under a Dynamic Oversaturation Regime with Implications for Energy Production from Subsurface Reservoirs
Authors: Reiss Amit Gilad , Wang Xin , Ye Yuqing , Kan Amy , Tomson Mason
Published: September 2024

Energy production from subsurface reservoirs perturbs the equilibrium between fluids and the surrounding rocks. As the saturation increases, nucleation begins, forming a scale that is detrimental to production. Inhibitor addition for scale prevention is a common practice with significant economic and environmental costs. Traditional experiments to determine induction times (tind) and evaluate inhibitor efficiency are performed under constant oversaturation. Similarly, constant oversaturation is used in both the empirical and the classical nucleation theory modeling schemes used for scale prediction. Subsequently, experiments and models do not address the dynamic nature of oversaturation increase during energy production. We developed an experimental system for quantitative investigation of nucleation kinetics under a regime of dynamic oversaturation and a simple algorithm for determining tind from laser measurements. Using our system, we studied the precipitation kinetics of CaCO3 minerals at a pH of ~6.76, ionic strength of I = 1m, temperature range of 50-90 oC, and varying rates of oversaturation increase. We quantified the effect of a potent inhibitor (Polyamino Polyether Methylene Phosphonate; PAPEMP) on the tind and the forming solid phase. Finally, we developed a numerical model that explicitly accounts for the dynamic nature of oversaturation. Here, we present our experimental system, results, and modeling scheme. We show that for a given set of conditions, calcite induction occurs at a similar oversaturation, regardless of the rate at which oversaturation increases. Moreover, we show that PAPEMP retards CaCO3 nucleation at below ppm levels and that it has a temperature-dependent effect on polymorphism. Lastly, we suggest that expanding existing models such that: t_ind=f(∆SI)*f(static) Where f(ΔSI) is a function of oversaturation with time and f(static) are existing modeling schemes, adequately describe the dynamic nature of oversaturation and show a form of f(ΔSI) that provides an excellent fit with measured tind.
Quantitative Elucidation of Catalytic Reaction of Truncated Aldehyde Dehydrogenase Based on Linear Free Energy Relationship

Published: September 2024

Some oxidoreductases can communicate directly and electrically with electrodes; this process is called direct electron transfer (DET)-type bioelectrocatalysis. Understanding its detailed mechanisms is essential for developing and improving DET-based bioelectrochemical devices. In this study, we investigated the pH dependence of kinetic and thermodynamic characteristics of a variant of an aldehyde dehydrogenase (ALDH) without the cytochrome c subunit (ΔC_ALDH) and compared it with that of a wild-type recombinant ALDH (rALDH). Owing to the pronounced DET activity of ΔC_ALDH at multi-walled carbon nanotubes, the voltammograms were analyzed to obtain the enzymatic parameters. The potential difference between the electrode-active site of the enzyme and electron donor (EE – ED) and the limiting catalytic current density (jcat) exhibited an ideal linear free energy relationship (LFER), suggesting that the catalytic reaction of ΔC_ALDH was controlled by the thermodynamic driving force without any specific interactions. We also measured the ferricyanide reductase activity in solution (ksol) to investigate the effect of electron acceptors (electrode and ferricyanide) on the enzymatic properties. The ksol of ΔC_ALDH has a pH dependence similar to that of jcat; therefore, the experimental data were kinetically analyzed based on the LFER by considering the potential difference between the electron acceptor and electrode-active site of the enzyme (EA – EE). By integrating the analytical results obtained from the DET-type acetaldehyde oxidation using an electrode and ferricyanide reduction in solution, the catalytic constant for the DET-type bioelectrocatalysis (kDET) and the surface concentration of the effective enzyme immobilized on the electrode (ΓE,eff) of ΔC_ALDH were calculated to be 5000 ± 2000 s–1 and 13 ± 7 pmol cm–2, respectively. This study achieved a detailed evaluation of the multi-step catalytic reactions of redox enzymes and can help elucidate the reaction mechanisms of DET-type bioelectrocatalysis.

Authors: Kumari Pallavi , Niyogi Anjan
Published: September 2024

This paper reviews the impact of technological advancements on consumer decision-making regarding hearing aid acquisition, focusing specifically on the Indian context. While innovations like smartphone connectivity, AI-driven features, and rechargeable batteries increase purchase intention (Manchaiah et al., 2021), a complex interplay of cultural, socioeconomic, and accessibility factors influences adoption rates. The paper examines how the urban-rural divide (Kumar et al., 2020), affordability challenges (Reddy & Nair, 2019), and cultural nuances (Sharma & Patel, 2022) shape technology acceptance in India. It also explores the potential of Tele-audiology (Chopra & Sharma, 2021) and government initiatives (Kumar et al., 2021) in promoting wider access to advanced hearing aids. The review highlights the need for manufacturers to adopt segmented approaches, healthcare providers to expand telecom-services, and policymakers to implement inclusive policies to address the unique needs of the Indian market.

The development of the concept of satire holds an important place in the philosophical content of Indian art as it has transformed in several ways reflecting the socio-cultural and political changes. Satire has been voiced in Indian art over the years through its varied expressions that are crucial to understanding the hidden content of commentary or the overtly implied motives of satire in different art forms. The purpose of my research is to explore two interdependent concepts, first, the kinship of satire to the concept of Indian moral philosophy; and second, the reflection of moral philosophy through varied expressions of satire in Indian art. Morality has had deep roots in Indian philosophy since ancient times. The moral and ethical framework of philosophy revolves around the concept of ‘Dharma’ that holds immense importance in the philosophical foundation of different schools such as Jainism, Buddhism, and Hinduism. It is also central to the metaphysical identity of the Indian culture that aims to foster ethical conduct through righteousness and justice. Indian art has evolved through the ages as a reflection of society and its influence on the formation of culture and values. Teachings of morality have been integral to the Indian culture rather than the biting language of satire that found its expressions in Indian art around the later stages of development, that is around the medieval period when a deeper inflow of foreign influence began entering the Indian cultural system. I aim to understand the evolution of morality from the ancient period progressing toward the critical harsh mockery of satire in contemporary Indian art.

Considerando que a indisciplina, no ambiente escolar, mais precisamente em sala de aula, nega a educação e afeta o bom desenvolvimento dos alunos, a referida pesquisa buscou realizar reflexões sobre essa temática. Para tanto foram realizadas pesquisa bibliográfica na literatura específica, e uma pesquisa de campo, com coleta de dados. Os sujeitos da pesquisa de campo foram três professores, do ensino fundamental I, com seus respectivos alunos, os quais fazem parte da escola analisada no artigo. A escola faz parte do Município de Olho d'Água das Flores – Alagoas, com pseudônimo “ESCOLA AZUL”. Por motivos de sigilo, foi decidido omitir o nome da escola. Usaram-se como ferramenta de pesquisa, questionários com perguntas objetivas sobre a temática indisciplina. Professores e alunos foram entrevistados no mesmo dia em que ocorreu a investigação. Essa pesquisa aponta a indisciplina como um tema complexo, que para solucionar esse problema precisa do envolvimento de toda a comunidade escolar. Porém, nesse contexto, o professor tornou-se, através de sua prática, o principal agente na busca da disciplina, com o objetivo de obter sucesso no processo ensino/aprendizagem, sendo orientando pelo coordenador pedagógico da escola, que o auxilia no planejamento, para conter a indisciplina no ambiente escolar.

O presente estudo aborda, a partir das experiências de escuta e acolhimento de jovens adolescentes numa escola municipal do Município de Uauá, no interior da Bahia. A adolescência é uma fase crucial no desenvolvimento humano, marcada por transformações físicas, psicológicas e sociais. Discute-se o rápido crescimento e
desenvolvimento biológico, mudanças psicológicas como a busca identitária e a
autonomia, e transição social da dependência para a autonomia. Destaca-se o papel dos
professores na compreensão e apoio aos adolescentes. A falta de preparo desses
profissionais para gerir essas mudanças é ressaltada, assim como a importância de ações

RECOVERY OF THE ORGANIC SOLVENTS FROM THE MULTICOMPONENT MIXTURE IN THE PROCESS OF THE FRACTIONAL DISTILLATION AND THE VACUUM DISTILLATION
Authors: Ciaciuch Anna , Sulewski Mariusz
Published: September 2024

In these times of sustainability, the purification and regeneration of used solvents is attracting a lot of interest for environmental reasons and to reduce production costs. The article presents research on the separation of organic solvents such as acetonitrile, methanol, acetone, and toluene from a multicomponent mixture of liquid organic waste. This is an element of the circular economy and prevents the emission of volatile organic compounds into the environment. In order to separate the mixture and recover the solvents, fractional distillation and vacuum distillation were used together with pre-treatment of the waste using sorption on silica gel and calcium oxide. The analysis of the waste composition and the mixture after the separation was performed by gas chromatography coupled with a mass spectrometer (GC-MS). As a result of the research, the acetonitrile concentration increased to 90.7% after fractional distillation.
Assessment of Vitellogenin Synthesis in Salvator merianae as a Biomarker of Exposure to Xenoestrogens in Terrestrial Ecosystems

Published: September 2024

The expansion of agriculture and livestock in Argentina has significantly increased the use of pesticides, adversely impacting animal and human health. These chemical compounds, acting as xenoestrogens, can disrupt the reproductive physiology of wildlife. In this context, vitellogenin, a liver protein typically elevated in oviparous females during reproduction, can also be induced in males and immature females by exposure to xenoestrogens. The aim of this work was to study the production of vitellogenin in response to exogenous estrogens in male Salvator merianae lizards, a species widely distributed in Argentina.  Eighteen adult tegus from the Universidad Nacional de Tucumán were used, distributed into three groups: males treated with 17 ?-estradiol, females in the vitellogenesis phase (positive control), and untreated males (negative control). Treated males received doses of 17 ?-estradiol every three days for two weeks, and blood samples were taken before and during treatment for analysis by SDS-PAGE, spectrophotometry, and immunohistochemistry. Results revealed a significant increase in triglyceride levels and the synthesis of a high molecular weight lipoprotein in treated males, a pattern similar to that observed in females during vitellogenesis and absent in negative controls. This pioneering study demonstrates the induction of hepatic vitellogenin in Salvator merianae males treated with estradiol, highlighting the potential utility of this species as a biomarker of environmental contamination by xenoestrogens.

Authors: ZAHIDUR RAHMAN FARAZI
Published: September 2024

In recent years, the integration of artificial intelligence (AI), blockchain technology, and machine learning has transformed credit risk mitigation strategies in the financial industry. This paper explores the practical applications of these technologies in identifying, assessing, and managing credit risk, with a specific focus on predictive analytics and decentralized frameworks. Through a comprehensive literature review and case studies, the research demonstrates how AI-driven algorithms, blockchain's transparent and immutable ledger systems, and machine learning models have enhanced the precision and efficiency of credit risk evaluations. Additionally, the study investigates how these innovations are being adopted by financial institutions to create more accurate credit scoring systems, reduce fraud, and optimize operational risk management. While these technologies hold great promise, challenges such as data privacy, regulatory compliance, and implementation costs remain significant barriers. The paper concludes with recommendations for overcoming these challenges and maximizing the potential of AI, blockchain, and machine learning in credit risk mitigation.
