МУЗЫКАЛЬНАЯ ПОЭТИКА АНТОНИО ВИВАЛЬДИ
Authors: ДЕМЧЕНКО А И.
Published: December 2024

В начале статьи даётся краткий обзор контекста эпохи и композиторского окружения Вивальди и после небольшой панорамы жанров, которые были для него периферийными (оперы, кантаты и оратории, произведения духовной тематики), следует рассмотрение его инструментальной музыки с господствующим акцентом на жанре сольного концерта, основоположником которого являлся Вивальди. Преимущественное внимание уделяется концертам для скрипки с оркестром, поскольку во всех отношениях именно они составили наиболее драгоценную часть наследия композитора. Наряду с достаточно тщательным изучением технологии концертного жанра, включая обсуждение знаменитого принципа «хорошо организованного контраста», определяющий пафос данной статьи состоит в утверждении двух ведущих ипостасей образного мира Вивальди: энергия активного действия и проникновенный лиризм. В завершение освещается вклад Вивальди в разработку программной музыки и того, что предвосхищало горизонты искусства эпохи Просвещения.

The article begins with a brief overview of the context of Vivaldi's epoch and composer's environment, and after a brief panorama of genres that were peripheral to him (operas, cantatas and oratorios, works with spiritual themes), a review of his instrumental music follows, with the dominant emphasis on the genre of the solo concerto, of which Vivaldi was the founder. Advantageous attention is paid to concerti for violin and orchestra, since in all respects they formed the most precious part of the composer's legacy. Alongside a fairly thorough study of the technology of the concerto genre, including a discussion of the famous principle of «well-organised contrast), the defining pathos of this article is the affirmation of the two leading hypostases of Vivaldi's imaginative world: the energy of active action and heartfelt lyricism. In conclusion, Vivaldi's contribution to the development of programme music and that which anticipated the horizons of Enlightenment art is highlighted.

ОЦЕНКА ПРОЦЕССА СОРБЦИИ КАТИОНОВ СВИНЦА НА ОРГАНОГЛИНАХ НА ОСНОВЕ БЕНТОНИТА И НЕИОНОГЕННЫХ ПАВ МОДЕЛЬЮ БЭТ
Authors: Герцен М.М. , Переломов Л.В.
Published: December 2024

Природные и модифицированные различными веществами глинистые минералы уже многие десятилетия используются в качестве адсорбентов для удаления тяжелых металлов из водных и почвенных экосистем. В зависимости от природы модификатора процессы поглощения поллютантов могут описываться различными сорбционными моделями. Для проектирования систем «адсорбент-адсорбат» важен выбор подходящих изотерм адсорбции для дальнейшей оценки практической применимости анализируемых сорбентов. В данной работе изучался процесс адсорбции катионов свинца органоминеральными системами на основе бентонита и неионогенных ПАВ с помощью модели БЭТ. Установлено, что по величине максимальной адсорбции исследуемые образцы глин образуют возрастающий ряд: бентонит < органоглина с кокамидом диэтаноламина < органоглина с лаураминоксидом < органоглина с алкилполиглюкозидом. Максимальное значение предельной адсорбции катионов свинца у органоглины на основе бентонита и алкилполиглюкозида равно 0,523±0,003 ммоль/г. Результаты сорбции катионов свинца анализируемыми сорбентами свидетельствуют о том, что модель БЭТ может применяться для прогнозирования изотерм бинарных компонентов.

Natural and modifi ed clay minerals have been used for decades as adsorbents to remove heavy metals from aquatic and soil ecosystems. The processes of pollutant absorption are described by various sorption models, depending on the nature of the modifi er. When designing adsorbent-adsorbate systems, it is important to select suitable adsorption isotherms for evaluating the practical applicability of sorbents. In this study, we investigated the adsorption of lead cation by organomineral systems based on bentonite and non-ionic surfactants using the BET model. We found that, based on the value of maximum adsorption, the clay samples form a series: bentonite < organoclay containing diethanolamine cocamide < organoclay including lauramine oxide < organoclay incorporating alkyl polyglucoside. The maximum adsorption capacity of lead cations in organoclays based on bentonite and alkyl polyglucosides was 0.523 ± 0.003 mmol/g.. The results of lead cation sorption by the analyzed sorbents suggest that the BET model can be applied to predict the behavior of binary component systems.

Published: December 2024

The MBX software provides an advanced platform for molecular dynamics simulations, leveraging state-of-the-art MB-pol and MB-nrg data-driven many-body potential energy functions. Developed over the past decade, these potential energy functions integrate physics-based and machine-learned many-body terms trained on electronic structure data calculated at the ``gold standard'' coupled cluster level of theory. Recent advancements in MBX have focused on optimizing its performance, resulting in the release of MBX v1.2. While the inherently many-body nature of MB-pol and MB-nrg ensures high accuracy, it poses computational challenges. MBX v1.2 addresses these challenges with significant performance improvements, including enhanced parallelism that fully harnesses the power of modern multicore CPUs. These advancements enable simulations on nanosecond timescales for condensed-phase systems, significantly expanding the scope of high-accuracy, predictive simulations of complex molecular systems powered by data-driven many-body potential energy functions.

Published: December 2024

Developing chemical combustion mechanisms for novel bio- and e-fuels is a challenge, given that many established mechanism analogies originate from fossil fuels. This work studies the ability of two new reaction network exploration methods, ChemTraYzer-TAD and PESmapping, to suggest potentially important reaction paths to combustion mechanisms, highlighting the differences and similarities of the two methods. In the reaction space of the ethyl-2-yl formate radical combustion, all expected important reactions are found, with many additional reactions suggested by one or the other method. This shows that the combination of both methods provides an optimal exploration result, i.e. both expected and novel reaction pathways.

Lipid membranes are central to cellular life. Complementing experiments, computational modeling has been essential in unraveling complex lipid-biomolecule interactions, crucial in both academia and industry. The Martini model, a coarse-grained force field for efficient molecular dynamics simulations, is widely used to study membrane phenomena but has faced limitations, particularly in capturing realistic lipid phase behavior. Here, we present refined Martini 3 lipid models with a mapping scheme that distinguishes lipid tails differing by just two carbon atoms, enhancing structural resolution and thermodynamic accuracy of model membrane systems including ternary mixtures. The expanded Martini lipid library includes thousands of models, enabling simulations of complex and biologically relevant systems. These advancements establish Martini as a robust platform for lipid-based simulations across diverse fields.
Room-temperature H2 splitting and N2-hydrogenation induced by a neutral Lu(II) complex

Published: December 2024

The direct splitting of the H2 and N2 molecules are challenging reactions that are closely related to the Haber–Bosch ammonia synthesis process. Until now, such reactivity has never been observed in the case of molecular lanthanide species. Here, we show that careful selection of the ligand scaffold allows the isolation and characterization of a kinetically stable but highly reactive Lu(II) complex. This divalent lanthanide species enables direct H2 splitting at room temperature, an unknown reactivity in lanthanide chemistry, which has been fully corroborated by DFT calculations. In addition, the Lu(II) complex readily binds N2, leading to an end-on coordinated diazenido (N2)2– lanthanide complex. The latter can be hydrogenated under very smooth conditions (ca. 1.2 bar H2, ambient temperature) to form a unique Lu(III)–NH2 complex. Direct N2 hydrogenation and cleavage are thus accessible using low-valent molecular rare-earth metal complexes.

Published: December 2024

Operando analysis is crucial for understanding the selectivity and stability of the electrochemical CO2 reduction reaction (eCO2RR). Existing operando techniques normally adapt single-compartment cells operating at low currents. However, high current densities on the order of 100 mA cm-2 are required for practical applications, and under these conditions, selectivity and reaction pathways can differ. Here, we developed an inline operando NMR method compatible with high-current reaction conditions. Demonstrating on a copper-catalyzed eCO2RR at a current of 100 mA cm-2, our NMR study revealed a fast decrease of Faradaic efficiency for formate and ethanol within the first few hours of reaction, accompanied by a pH decrease from 14 to 8 within the first hour and a continuous concentration increase of bicarbonate. At 200 mA cm-2, the bicarbonate concentration reached the saturation point of 3.34 M within five hours. Water crossover was simultaneously observed and quantified via a deuteration technique and showed a strong current dependency. Our NMR observations revealed a highly dynamic environment of copper-catalyzed eCO2RR at high currents and will further aid the design and optimization of this reaction. Using on a common flow cell and a benchtop NMR system, the new operando approach is accessible by non-NMR experts and readily applicable to a wide range of catalysts, electrolyte compositions and reactor designs for eCO2RR.

Published: December 2024

Rising salinity levels in the coastal regions of Bangladesh, driven by climate change, significantly affect agricultural productivity. Adaptation strategies to mitigate the effects of salinity are crucial for increasing crop production. This paper examines the adaptation strategies employed by male and female sunflower farmers in response to salinity intrusion in the south-central coastal zones of Bangladesh. We collected data through a household survey of 50 men and 50 women, supplemented by interviews and focus group discussions with farmers. The sample size was determined using a probabilistic sampling method. The questionnaire included open-ended and closed-ended questions and pretested with farmers before conducting final interview. Our results indicated that significant variables influencing adaptation strategies among male sunflower farmers included age, communication exposure, and training experience (p < 0.05). For female sunflower farmers, significant factors were age, communication exposure, training experience, and cultivated sunflower area (p < 0.01). Both regression models exhibited a satisfactory fit. Additionally, the primary adaptation strategies adopted by both male and female farmers included the application of fertilizers and pesticides. These findings provide valuable insights for policymakers in formulating future farm-level gender based adaptation strategies for cultivating sunflower.

Published: December 2024

This research was conducted in Budhanilkantha, Kathmandu from February to June 2023 to study the effects of different concentrations on growth, flowering and yield of tomato in Randomized Complete Block Design (RCBD) with five treatments: control (T0), two levels of chelated zinc (30 ppm - T1 and 60 ppm - T2), and two levels of borax (30 ppm - T3 and 60 ppm - T4), applied 15 and 35 days after transplantation (DAT). The results showed that chelated zinc at 30 ppm significantly enhanced plant height (86 cm), leaf number (52.47), branch number (8.21), fruit clusters (19.32), fruit number (22.73), fruit diameter (5.58 cm), fruit weight (59.71 g), and yield (56.56 t/ha). Borax at 30 ppm promoted early flowering (23.70 days). Higher concentrations of both micronutrients resulted in reduced growth and yield. The findings suggest that foliar application of 30 ppm chelated zinc and borax can optimize growth and yield of tomato. The study highlights the potential of these easily accessible micronutrient sources to significantly enhance tomato productivity under polytunnel cultivation.
A review on co-composting of biosolids and its use in crops cultivation for agriculture sustainability

Published: December 2024

Generation and disposal of biosolids (solid and semisolid materials left after the wastewater treatment) has becoming a challenge globally. A large number of objectionable components like heavy metals, pesticides, detergents and pathogens restricts the direct application of biosolids in the cultivation of agricultural crops as it contaminates the soil as well as the cultivated crops and causes health issues. Co-composting of biosolids can be a viable option to utilize the biosolids in a definite proportion along with different types of biodegradable materials (co-substrate) such as, kitchen waste, agricultural residues, forestry waste and waste from the animal husbandry etc. Co-composting improves the nutrients status of the composted biosolids and reduce the risk of accumulation of toxic heavy metals and pathogens in the soil and cultivated crops. The application of biosolids compost in to the soils significantly improve the physical structure, nutrients composition and microbial profile of the soils and subsequently enhance the crops productivity. It also reduces the risk of contamination of the soils and cultivated agricultural crops in comparison to the direct use of biosolids in soil amendment. In this paper we discussed the use of biosolids in agriculture, co-composting of biosolids with different co-substrates and their application in the cultivation of different agricultural crops for sustainable agriculture production.

Declining soil fertility and the limited use of sustainable soil organic amendments has resulted in reduced crop productivity in Nepal. This study assessed biochar produced from rice husk and sawdust at three different pyrolysis temperatures (200°C, 400°C, and 600°C), characterized their properties and applied them as soil amendments to test their agronomic effect on kidney bean production. The highest biochar yields were achieved at lower pyrolysis temperatures (200°C) for both rice husk (40%) and sawdust (38.4%). Ash content was significantly higher in rice husk (33.6%) compared to sawdust biochar (5.8%) across all temperatures. Sawdust biochar had higher volatile matter (91%) than in rice husk biochar (61.5%). The fixed carbon content was greater at 200°C and 400°C for both rice husk and sawdust biochar. FT-IR result showed significant loss of aromatic groups with increasing temperature. Biochar from all three temperatures was then used in a pot experiment to grow kidney beans and assess their agronomic effects. Seven treatments were used: control (CK), rice husk biochar at 200°C (RH200), 400°C (RH400), and 600°C (RH600), sawdust at 200°C (SD200), 400°C (SD400), and 600°C (SD600) following a completely randomized design with 3 replications per treatment. Cattle manure was applied uniformly (25 t ha-1) across all treatments, including the control. Over 50 days, SD400 resulted in the tallest plants, SD600 produced the thickest stem and RH600 had the highest number of leaves. Biochar applications showed significantly higher fruit weight and counts, which was on average 24 % higher than the control, with no significant differences between rice husk and saw dust biochar at three different temperatures. The study suggests that high quality biochar can be produced from both rice husk and saw dust and its application boost legume yields, which is crucial for enhancing country’s nutritional and food security.

Chemical bonds are one of the materials in chemistry that are abstract in nature so that many students have difficulty learning chemical bonding material. This study aims to identify the learning difficulties frequently faced by students in understanding chemical bonding materials and various misconceptions that commonly occur in their understanding. Data collection was carried out using a systematic literature review method with several predetermined criteria. The result is that the learning difficulties experienced by students are caused by many factors, one of which is conceptual error or misconception. At present, many methods have been developed to identify students’ misconceptions about chemical bonding material such as diagnostic tests such as two-tier, three-tier and four-tier diagnostics.

This study is aimed at investigating the volatile constituents of the air-dried roots of Celtis zenkeri. The volatile oil was extracted using hydro-distillation method and characterised using gas chromatography-mass spectrometry (GC-MS). The volatile oil was screened against six selected bacteria and four fungi strains using the agar diffusion method. The molecular docking study of the identified compounds was conducted to investigate their binding pattern with the substrate and nucleotide complexes of Enterococcus faecium aminoglycoside-2’’-phosphotransferase-IIa [APH(2’’)-IIa] (PDB ID: 3HAM) and full-length Lanosterol 14 alpha-Demethylases of Prominent fungal pathogens Candida albicans (PDB ID: 5V5Z). The yield of the volatile oil (% w/w) root of C. zenkeri was 0.79%. Six compounds were identified in the root essential oil representing 80.07% of the volatile oil. 2-methyl-1-pentene (40.01%) was the most abundant compound in the root essential oil. The volatile oil from roots of the C. zenkeri exhibited good activity against all the screened bacteria and fungi strains at a concentration of 12.5-100 mg/mL when compared with Gentamicin for bacteria and Tioconazole for fungi.

Published: December 2024

This study explores the implementation of text mining in audit risk assessment. We use the latent Dirichlet allocation (LDA) algorithm to reveal hidden topics representing risks in the management of the Indonesian School Operational Assistance Fund (BOS Fund). Using 1,460 news data points from a leading Indonesian news portal, this study proves that using text mining with the LDA algorithm effectively identifies the risks of an audit object. This study makes two important contributions to the information systems and audit literature. First, it provides evidence from online news archives to facilitate a more reliable, current, and comprehensive selection of potential audit areas by encompassing evolving social realities and facts. In the contemporary era, the accelerated and precise dissemination of information via the Internet renders the LDA approach feasible and prudent. Second, it provides a practical and applicable framework for audit risk assessment using nonfinancial sources from independent parties, which can be used as a guide for the development of audit models in the public and private sectors.
ON THE PSYCHOLOGICAL MEANING, FUNCTIONS AND GENESIS OF EXPRESSIVE MOVEMENT
Authors:   Lomonosov Moscow State University, Ailamazyan Aida M. ,   Federal Scientific Center of Psychological and Multidisciplinary Research
Published: December 2024

The article addresses issues of the significance and role of expressive movement for mental development, in the formation of personality.
It considers the genesis of expressive movements from the first manifestations
of emotional reactions through the arbitrary acquisition of expressive behavior to complex mediated types of expressive activity. As well it describes the
process of separation and possible divergence between inner and outer sides
of expressive behavior and its significance in the formation of differentiated
and mediated personality structure. The path of evolution of the expressive
components of emotional reactions is related to the fact that they acquire an
anticipatory character, decrease in their expression, and are reduced eventually
to rudimentary forms. Those rudimentary actions become a basis of internal
emotional and semantic orientation, make an important part of an emotional
image and internal psychological space of the person. Along with the transformation and swerving of an expressive movement into its internal form, there is
no less important process of unwinding in the external form of a psychological
gesture and psychological space. As a rule, such unwinding takes place in special conditions, at occurrence of a special state or mode of work of the psyche, it
presupposes changes and transformations in movements. The question is raised
about autocommunication, the emergence of internal dialog on the basis of
kinesics, expressive movement.

“Cornelia”, the manuscript by Nikanor Ivanovich Oznobishin,
which was discovered by O.M. Buranok, is the earliest (1761) of the currently
known translations of Miguel de Cervantes into Russian. Prior to that, as
A.D. Umikyan points out that the novella “Two Mistresses” (“Las dos doncellas”) from the “Exemplary Novels” was considered the first translation into
Russian (completed and published at Moscow University in 1763). Oznobishin
translated Cervantes not from Spanish, but from French, which was typical
for translations of the 18th century. Cervantes’ translations into Russian were
studied earlier by such researchers as B.A. Krzhevsky, N.Ya. Berkovsky,
K.N. Derzhavin, B. Frank, M.V. Alpatov, M.P. Alekseev, V.E. Bagno, etc.
However, none of them knew the translation of the novella ‘Senora Cornelia’
by N.I. Oznobishin. Thus, the article aims at comparing that translation with
other later translations by F. Kabrit in 1805 and B. Krzhevsky in 1934; analyzing the content of N.I. Oznobishin’s translation; determining the place of this
translation in the context of translated literature of the 18th century in Russia

The article refers to the relationship between fathers and children on the pages of literary works and in everyday life in the late 18th – early
19th centuries. The relationship between fathers and children is considered
on the examples of two families – the families of Decembrists P.I. Pestel and S.I. Muravyov-Apostol. It is concluded that in those families there was a serious worldview conflict between parents and children. The literature of that
epoch failed to see and describe the conflict, traditionally continuing to consider children as mere executors of their parents’ instructions.

Elektro-ensefalogram (EEG) taraması, beyinde oluşan elektriksel aktiviteleri ölçümleyerek beynin fonksiyonlarını başarılı şekilde yerine getirip getirmediği hakkında bilgi veren bir tıbbi görüntüleme sistemidir. İnsan kafatasına elektrotlar yerleştirilerek yapılan bu tarama sinyalleri kişinin vücudundaki diğer aktivitelerden ve dış faktörlerden dolayı gürültüye maruz kalmaktadır. Harmoni arama (HS) algoritması, müzik eserleri oluşturulurken gerçekleştirilen besteleme sürecinden esinlenen bir yarı-sezgisel algoritmadır. Bu çalışmada HS algoritması ve sonrasında geliştirilen varyantları ile EEG sinyallerinin gürültülerden temizlenmesi problemi optimize edilmeye çalışılmış ve varyantların bir büyük veri optimizasyon problemi olan bu problem üzerindeki başarımları kıyaslanmıştır. İncelenen sonuçlar, büyük veri optimizasyon problemleri üzerinde sonradan geliştirilen HS varyantlarının, HS algoritmasının ilk versiyonundan daha üstün performans gösterme kabiliyetine sahip olduğunu ortaya koymaktadır.
THE INDUS VALLEY CIVILIZATION: FEATURES OF URBAN PLAN
Authors: F. Halemani Pramod
Published: December 2024

The Indus Valley Civilization is another distinctive prehistoric civilization commonly referred to as the Bronze Age Civilization, which is perhaps the most developed prehistoric civilization, notable for showcasing great advances in town planning and architectural development. The North Indian subcontinent Indus Valley civilization with northwest India, Northeast Afghanistan, and a major part of Pakistan, possesses a separate urban infrastructure with maintained street plans, drains, residences, public edifices, and monumental establishments such as the Great Bath. The arrangement of the cities shows a typical settlement pattern of a civilized society, and the manner in which these urban structures have been designed, built, and integrated also suggests the kind of engineering and sanitation needs that this civilization could cater to were apparent. Unlike earlier sites, the streets are right-angled, and the covered drain system and burn bricks are a sign of planning. The complex includes clearly distinguishable economic facilities – granaries and wells that prove efficient use of resources. Further, the homogeneity of the building materials and the organization of the city layout implies centralized control over construction and city maintenance. Thus, this research focuses on the aspects of the town plan of the Indus Valley Civilization, city streets, sewage, public and private construction, and construction materials and demonstrates how that civilization was very advanced in antiquity. The findings are useful for enhancing the knowledge about early urbanization and its impact on other civilizations.
