Authors: ФУРУКИН А В.
Published: December 2024

Валторна является одним из богатейших инструментов духового и симфонического оркестров. Инструмент прошел огромный путь от охотничьего рога до полноценного инструмента и на протяжении всего периода становления инструмент отличался большим разнообразием выразительных возможностей. Со времени первого употребления в оркестре валторна проходит большой путь эволюции. Когда валторна оказалась в оркестре это был охотничий рог, закрученный от полутора до четырех с половиной оборота, сегодня же это инструмент, с большим разнообразием выразительных возможностей. Учитывая ее природу, богатый тембр, большие динамические возможности, конструктивные особенности современных моделей, мы можем с уверенностью сказать, что у валторнистов сегодня есть все возможности для раскрытия своего творческого потенциала и решения различных художественных задач.

The French horn is one of the richest instruments of the brass and symphony orchestras. The instrument has evolved from a hunting horn to a full-fledged instrument, and throughout the entire period of its development, the instrument has been distinguished by a wide variety of expressive possibilities. During its first performance in the orchestra, the French horn goes through a long evolutionary path. When the French horn appeared in the orchestra, it was a hunting horn, twisted from one and a half to four and a half turns, today it is the same instrument, with a wide variety of expressive possibilities. Given its nature, rich timbre, great stimulating possibilities, design features of modern models, we can confidently say that French horn players today have every opportunity to reveal their creative abilities and solve various artistic problems.

Published: December 2024

Статья посвящена жанрово-стилевому анализу песенного фольклора региона Верхнего Поочья - одного из древнейших очагов народного музыкального искусства России. Рассматриваемая территория является местом расселения славянского племени вятичей в V-VII веках нашей эры в пределах бассейна верхнего течения реки Оки, которая географически локализована в границах современной Калужской, Тульской, Орловской и части Брянской и Смоленской областей. В качестве инструмента исследования разножанровых песенных образцов выступает структурно-типологический метод, позволяющий выявить музыкально-стилевые черты рассматриваемых напевов. На основе полученных сведений о ритмическом, ладовом, мелодико-интонационном и многоголосном строении можно составить объективную картину бытования музыкально-этнографической традиции Верхнего Поочья с позиции определения временного исторического пласта произведений фольклора, места песенных жанров в структуре традиции в качестве ядра и периферии.

The article is devoted to the genre and style analysis of the song folklore of the Upper Pooch region, one of the oldest centers of folk music in Russia. The territory in question is the place of settlement of the Slavic Vyatichi tribe in the V-VII centuries AD within the basin of the upper course of the Oka River, which is geographically localized within the borders of modern Kaluga, Tula, Oryol and parts of the Bryansk and Smolensk regions. A structural and typological method is used as a research tool for multi-genre song samples, which allows to identify the musical and stylistic features of the tunes under consideration. Based on the information obtained on the rhythmic, fret, melodic-intonation and polyphonic structure, it is possible to make an objective picture of the existence of the musical and ethnographic tradition of the Upper Pooch region from the position of determining the temporary historical layer of folklore works, the place of song genres in the structure of tradition as the core and periphery.

Revisión teórica sobre la innovación educativa: análisis de perspectivas académicas contemporáneas
Authors: Sujatovich Luis Mauro , Brocca Débora
Published: December 2024

Se revisa el concepto de innovación educativa a través de un análisis de definiciones teóricas provenientes de diversos autores y organismos. A lo largo del texto, se examinan definiciones de Macanchí-Pico et al., (2020), Martínez-Bonafé y Rogero-Anaya (2021), Prendes-Espinosa y Cerdán-Cartagena (2021), Orrego-Tapia (2022), Barragán-Perea (2023), Fuerte (2024), Rodríguez-Barboza et al. (2023), Bautista (2024), Rodríguez-Rodríguez (2024) y Vaca-Rueda y Sánchez-Soriano (2024), para identificar tanto sus fortalezas como sus limitaciones. El análisis revela que muchas definiciones tienden a restringir la innovación educativa a aspectos tecnológicos y metodológicos, sin considerar dimensiones más amplias del proceso educativo. Se argumenta que una comprensión más profunda de la innovación debe incluir un cambio cultural y un enfoque pedagógico integral, que contemple las dimensiones culturales, sociales y emocionales del acto educativo. La revisión teórica busca contribuir a un discurso académico que promueva prácticas educativas más inclusivas y transformadoras, capaces de enfrentar los desafíos del contexto educativo contemporáneo. El artículo concluye con una llamada a redefinir la innovación educativa más allá de los enfoques técnicos, proponiendo una visión que abarque un cambio significativo en la práctica pedagógica y en la formación docente.

Published: December 2024

El crecimiento exponencial de la población mundial ha llevado a una producción excesiva de plásticos, afectando gravemente a los ecosistemas terrestres y acuáticos, y convirtiéndose en un problema ambiental significativo. El objetivo de esta investigación fue evaluar la presencia de microplásticos en el agua y la arena del Refugio de Vida Silvestre Marino Costero Pacoche (RVSMCP) y en la playa de Tarqui. Se georreferenció el área para su delimitación y se llevó a cabo la recolección de muestras de arena y agua, cuantificando los microplásticos según tamaño, tipo y color. Además, se realizó un análisis de varianza (ANOVA) para identificar diferencias significativas en la cantidad, tipo y tamaño de los microplásticos. En Pacoche no se detectaron microplásticos en la arena; sin embargo, en el agua se encontraron 8 fibras de 0.01 milímetros. En la playa de Tarqui se hallaron 49 partículas de microplástico, predominando los films. La ausencia de macroplásticos en Tarqui sugiere que las fuerzas coligadas dispersan los plásticos, mientras que las 8 fibras encontradas en el RVSMCP se deben a los residuos de la pesca artesanal permitida en la zona.

Published: December 2024

Una forma de reducir el negativo impacto ambiental que presenta la extracción de áridos naturales, es el aprovechamiento de los residuos industriales como material de construcción. Un ejemplo de ello son las escorias negras de horno de arco eléctrico, de las cuales en Cuba, en la empresa siderúrgica “José Martí”, se almacenan elevadas cantidades, sin valor de uso y con disímiles aplicaciones posibles en la rama de la construcción. En la investigación se evaluó la influencia del empleo de estas escorias en las propiedades del hormigón de cemento portland, como reemplazo parcial o total de los áridos gruesos convencionales. Fueron diseñados hormigones con porcientos de reemplazos de 25%, 50%, 75% y 100%, determinando propiedades en estado fresco y endurecido, comparando con un hormigón patrón. Se demostró que las propiedades de los hormigones con escorias fueron similares o superiores a las del hormigón patrón, lo que brinda fiabilidad a su empleo.

Binding mechanism of adenylate kinase-specific monobodies
Authors: Nakamura Ibuki , Amesaka Hiroshi , Nagao Satoshi , Negi Shigeru , Tanaka Shun-ichi , Matsuo Takashi
Published: December 2024

Monobody, an antibody-mimetic protein, regulates enzyme functions through protein-protein interactions. In this study, we investigated the binding mechanisms of monobodies to adenylate kinase (Adk). Calorimetric and X-ray crystallographic analyses revealed that CL-1, a monobody specific for the CLOSED form of Adk, binds to the CORE domain of Adk in an enthalpy-driven manner, forming several hydrogen bonds and a cation-π interaction at the protein interface, without perturbating the Adk backbone. In contrast, OP-4, an OPEN-form-specific monobody, exhibited the entropy-driven binding. 1H–15N 2D nuclear magnetic resonance (NMR) and 31P-NMR studies revealed conformational perturbations to Adk by OP-4, while substrate access remained intact. The different thermodynamic and structural effects between the monobodies highlight the diverse binding mechanisms among monobodies.

Published: December 2024

Neural cells have limited self-repair ability, and the therapeutic approaches for treating nerve injuries rely heavily on surgery. Hindered by the lack of donor tissues and the complex neural environment, it is of great interest to develop biomaterials to support neural regeneration. Self-assembling peptides with fibrous structures that mimic the extracellular matrix have become potential therapeutic agents for neural regeneration. Previously, we identified peptide sequences derived from enhancing factor-C (EF-C), which are neurotrophic without additional supplements or growth factors. Here, a library of nine EF-C variants is designed by varying the hydrophobic core of the peptide backbone since a detailed understanding of how hydrophobic interactions impact self-assembly and, subsequently, bioactivity is lacking. The physicochemical properties, including binding affinity, secondary structure, and assembled morphologies, of these variants are thoroughly analyzed. To obtain information at the molecular level, computer simulations based on AlphaFold 3 models are used to investigate the stability of EF-C peptide fibrils and their assembly. Our simulations provide theoretical insights that explain the differential assembly and stability of EF-C variants. In addition, the EF-C variants are tested for bioactivity in a human neuroblastoma cell line (SH-SY5Y) to establish the structure-property relationship. The structure-forming EF-C variants facilitated cell viability and differentiation of SH-SY5Y. The combination of experimental and computational approaches paves the way for the design of novel peptide sequences for neural regeneration.
Molecular Dynamics-Assisted Interaction Between HABT and PI3K Enzyme: Exploring Metastable States for Promising Cancer Diagnosis Applications
Authors: Santos Rodrigo Mancini , Ramalho Teodorico Castro
Published: December 2024

Local nonequilibrium approach has been used for many purposes when dealing with biological systems. Not only for unravel important features of cancer development, a disease that affects the life of many people worldwide, but also to understand drug-target interactions in a more real scenario, which can help to combat this disease. Therefore, aiming to contribute for new strategies against cancer, the present work used of this approach to investigate the spectroscopy of 2-(2’-hidroxi-4’-aminophenyl)benzothiazole (HABT) when interacting with PI3K enzyme, a widely associated target for the mentioned illness. The study consisted in evaluating the Excited State Intramolecular Proton Transfer (ESIPT) performance of HABT, in spectroscopic terms, when interacting with PI3K enzyme in a local nonequilibrium regime. This scenario could be considered by investigating the metastable states of HABT in this system. From this, it was possible to observe that the ESIPT performance of HABT considerably differ when comparing the solution and protein environment, where 63% have appropriate geometry in the protein environment, against 97% in the aqueous environment. Thus, from an entirely theoretical methodology, the present work provides insights when modelling biological systems and contributes significantly for a better comprehension of promising probes for cancer diagnosis.

Authors: Farinha Andreia , Van der Kraan Martijn , Witkamp Geert-Jan
Published: December 2024

In an experimental study using a multipurpose pilot plant suitable for intensively contacting water with supercritical carbon dioxide (scCO2) it has been demonstrated that scCO2 can take up perfluorooctanoic acid (PFOA) from water to levels down to the low µg/L level in the water. The water initially contained 100 µg/L of PFOA in all experiments. PFOA has been removed from 6 L of water for more than 98.5% using supercritical CO2 (323 K, 250 bars) in semi-continuous operation (24 L/hr). After 20 mins at 250 bar more than 90% of the PFOA was removed from the water. Batch operation (at 323 K) showed that the removal percentage decreased with pressure/density: 250 bar (834 kg/m3): 93%, 150 bar(700 kg/m3): 91 %, 105 bar(416 kg/m3): 69 %. The extracted PFOA was not recovered.

Published: December 2024

Nitrogen-doped carbon-based single-atom catalysts offer unique and tunable active sites to catalyze a wide spectrum of electrochemical processes. Despite recent progress on single-atom electrocatalysis, their potential application to upgrade biomass-derived chemicals has been rarely investigated. Herein, we carried out density functional theory-based screening of metal-nitrogen-carbon (MNC) single-atom catalysts for electrocatalytic furfural reduction. Using furfural’s adsorption strength as a descriptor, we identified CrNC to be promising to promote furfuryl alcohol production in contrast to other single atom motifs which are only selective to hydrofuroin. Its higher selectivity towards furfuryl alcohol can be attributed to the enhanced adsorption strength of furfural via chemisorption of the carbonyl group and its overall enhanced oxygen binding strength. We then synthesized the single-atom motifs via their incorporation in a highly porous nitrogen doped carbon synthesized through an ionothermal templating process. In agreement with our predictions, CrNC was able to produce furfuryl alcohol with Faradaic efficiency of ca. 18 %, while Co-, Fe- and NiNC motifs selectively produce hydrofuroin, with limited Faradaic efficiencies to furfuryl alcohol < 3 %. Our work showcases a workflow to design and optimize single-atom catalysts to bridge the outer-sphere and inner-sphere selectivity in electrosynthesis from biomass-derived chemicals.
Schrems III avagy mi lesz veled transzatlanti adattovábbítás? - Gondolatkísérlet az EU-USA Adatvédelmi Keretrendszer Határozat érvényességéről
Authors: Kis Kelemen Bence
Published: December 2024

The United States of America and Europe are each other's most important cooperative partners. This naturally includes the economic relationship based on the transfer of personal data. Over the past nearly decade, this transatlantic data transfer has operated amid continuous legal uncertainties due to the repeated invalidation of the European Commission's adequacy decisions and issues related to the applicability of standard contractual clauses. The problem appears to be currently resolved thanks to the EU-US Data Privacy Framework Decision. However, this Commission decision has already been challenged, and a new procedure is expected to begin this year. The purpose of this study is to conduct a thought experiment to examine the validity of the mentioned decision, which could serve as guidance for future legal practice and provide forecasts for economic actors about expected developments. The paper's conclusion is that due to the unchanged violation of fundamental rights, the EU-US Data Privacy Framework Decision is likely invalid.
Az egyenlő bánásmódhoz való jog és a platform munka, különös tekintettel a platform alapú munkavégzés értékelésére
Authors: Hadady-Lukács Adrienn
Published: December 2024

The digital transition has a fundamental impact on everyday life, including the world of work. While working through digital work platforms offers numerous opportunities, it also presents several challenges regarding platform workers’ rights. The paper focuses on platform workers’ right to equal treatment and aims to review the questions and challenges that arise regarding the evaluation of platform workers by consumers. The legal problem is not caused by taking consumer feedback into account per se, but by the fact that the platform relies on such consumer feedback in a different manner and to a different extent than would be the case in traditional employment. Consequently, consumer evaluations and ratings raise several questions regarding the reliability and legality of such feedback.

Neutron noise control techniques for VVER core
Authors: Arkadov G. V. , Slepov M. T.
Published: December 2024

Many research staffs and groups have paid considerable attention to the issues of noise analysis and control of nuclear power plant operation parameters. This is reflected in the scientific environment in the form of numerous publications, monographs, articles, and reviews devoted to the study of noise components of various variation signals of reactor plants. However, despite the advanced theoretical works on this topic, applied research, i.e. direct reactor experiments, remains aside from the interests of both local and foreign scientists. The need of practical research is due to the complexity of interpretation of a variety of anomalies detected by noise methods, as well as the need to fine-tune various models. In addition, the spectral images of equipment can differ significantly not only between different designs of reactor plants, but also within the same-type units at one NPP. These problems cannot be solved by theoretical or computational methods alone, or by using simulation modeling. The situation is complicated by the fact that noise studies are a complex task both in terms of selecting noise data sources and interpreting the obtained information. Probably, these reasons explain the significant decrease of interest to experimental works on noise subject at various reactor plants both in the world practice and in Russia. The paper briefly discusses some possibilities of methods of neutron-noise control of cores aimed at improving the reliability and safety of NPPs. In addition, the article considers ways to reduce the labor intensity of their use for the earliest possible detection of anomalous condition of various equipment.
Diagnostics of VVER-1000 core states by reactivity perturbations
Authors: Shpitser V. Y. , Krivin V. V.
Published: December 2024

The self-sustained nuclear fission chain reaction is based on the probabilistic nature of fundamental physical processes. The measure of the dynamics of these processes (state identifier) is taken to be reactivity as a special physical property of the medium or technical system. The paper proposes to attribute reactivity to the class of random functions with zero mathematical expectation in the stationary critical state. Fluctuations with respect to zero value are perceived as a result of external factors causing an instantaneous response of the core of reactor plants operating at the installed power for the main part of the operating time. This definition is sufficient to develop methods of technical diagnostics based on perturbations of the reactivity of the core. The reactor core is considered as a stochastic object that is kept within the normative field of its design and regime characteristics. According to the archive data of reactivity ‘measurements’, it is possible to correlate to certain states of the reactor core the fragments of stochastic time series, which would serve as identifiers of these states. The set of such fragments (tests) constitutes a library of NPP operation experience. In the present work, the effects of an external Poisson perturbation of reactivity and the classification of neutron density modulations arising therefrom are considered in the framework of the one-group kinetics model. The reflection in the probabilistic characteristics of neutron density of random static and dynamic regime factors through reactivity is perceived as evidence of generation of defectiveness of the reactor core. The deterministic component of neutron density is described quite accurately by the equations of kinetics and corresponds to the trend of the mathematical expectation of reactivity with respect to zero value. A procedure of processing the data of neutron flux control equipment and reactor intrinsic control system is proposed, which includes formation of a library of test perturbations on the basis of archived data; analysis of responses by the Kolmogorov-Smirnov criterion of agreement between the empirical distribution functions of the current sample of empirical data and those calculated by the equations of kinetics on the basis of the library of perturbations.  It is argued that the proposed procedure is a means of identifying the defect level of the core and can also be used as an event simulator in deep learning of a classifying neural network.  The results refer to the achievements of neutron-noise diagnostics.

Authors: But Tetiana , Frankova Iryna
Published: December 2024

Introduction. Medical competence and effectiveness of treatment depends not only on "hard skills" - timely diagnosis and treatment selection according to the latest protocols, but also on "soft skills" - communication skills of the doctor, which constantly should be improved.

The issue of reproductive choice in obstetric or gynecological practice is an emotional challenge for the family. Only the patient and her partner can make the right decision, taking into account their resources available and moral values. The medical information should be provided according to objective data rather than from the subjective position of the doctor. Braking bad news is also a challenge for the doctor.

Aim. To implement in routine practice the protocol of consistent communication of the obstetrician-gynecologist with the patient, starting from the telephone invitation to a face-to-face consultation and ending with further follow-up with the family.

Method. A literature search for key words in scientific literature databases was conducted and a protocol for braking bad medical news was adapted in accordance with the request of an obstetrician-gynecologist in a situation of reproductive choice.

Results. The protocol includes six consecutive steps to build an interview between an obstetrician-gynecologist and a patient in a women's clinic. Those steps are: setting up the interview, assessing the patient’s perception, obtaining the patient’s invitation, giving knowledge and information to the patient, addressing responses, strategy and summary. Specific examples of dialogues, phrases to use, and phrases to avoid in the communication process  are suggested. The article also presents the communication tools on how to work out denial, explanation, "here and now" and burn out prevention techniques.

Conclusion. We should be acknowledge the importance of the doctor's good communication skills at all stages of caring for families at risk of perinatal loss. The protocol of braking bad news in obstetric and gynecological practice is a classic one, it has already passed the test of time in world medical practice. Its further implementation in Ukraine is an important step.

Lagos State has experienced adverse pollution as a result of lack of proper waste management and diverse industrial activities within its environs. The repercussion of this has consequently led to the deplorable state of the environment as well as the low quality of health amongst residents. Waste management has become a huge and intricate problem due to geometric population growth, urbanisation, industrialisation and the rising standard of living. This study investigated Plastic and Iron Waste Recycling Pollution in Lagos State, Nigeria. This study concluded that hazards of Plastic and Iron Waste Recycling Pollution in Lagos State; the drainage systems habitually blocked causing yearly flooding which usually lasted throughout the rainy seasons from April to October and displaced millions of residents. The clogged sewage systems became the perfect breeding environment for mosquitoes and flooding washed away footpaths caused people to move around in dirty water from overflowed gutters and polluted major sources of drinking water which led to the spread of cholera and typhoid fever. Also, higher levels of toxic heavy metals were observed among residents at close proximity to recycling iron factories. For environmental sustainability in Lagos State plastic and iron waste recycling pollution must be seriously cautioned in following; environmental impact assessment is necessary for any development in Lagos State, recycling programmes and waste to energy facilities can be reawaken with modernised and ecological friendly technologies.

This paper investigated the impact of financial sector development on agricultural output from 1981 to 2023 both in the short and the long run. The descriptive statistics and stationarity tests were conducted prior to the long run test using the Johansen co-integration and the Vector Error Correction Model (VECM). The Johansen test showed evidence of long run causality among the variables in the model. The serial correlation and the heteroscedasticity tests were conducted in addition. The result revealed the presence of linkage between lending rate, exchange rate and agricultural output. Loan to private sector and loan to agricultural sector as a proxy of financial sector development positively affected agricultural output in the short run. In the long run, lending rate and loans to private sector were negatively related to agricultural output while loan to agricultural sector had positive effect on output. The positive effect was, however, insignificant in the long run. This implies that in addition to finance and credits, peripheral factors such as insecurity, poor infrastructure, supply chain disruptions and low productivity are pervasive in their influence on agricultural performance to agriculture in Nigeria over the long term. The study recommended that the Central Bank of Nigeria through its monetary policy tools should ensure loans through the deposit banks are made accessible to genuine and credit worthy farmers at the lowest possible cost while addressing the insecurity issue.

The increasing globalization of businesses has led to the emergence of a diverse workforce, which requires effective cross-cultural management strategies to ensure organizational growth. This study evaluated the relationship between cross-cultural management on global human resources management and organizational growth in Lagos, Nigeria. A survey research design was used to collect data from 250 respondents on cross-cultural management practice and organisational growth. The findings indicated that there is a strong positive relationship between cross-cultural management and organizational growth. The study recommended that organisations in Lagos should incorporate cultural training programmes for their employees to improve their intercultural competence. Cultural training programmes can help employees to understand and appreciate different cultural backgrounds, leading to better communication and collaboration in the workplace.

Micronutrients, required in trace amounts, are crucial for crop growth and metabolic activities. Maize is susceptible to micronutrient deficiencies and exhibits hidden hunger symptoms when lacking essential nutrients. This study, conducted at Gauradaha Agriculture Campus, Jhapa, from January to June 2023, aimed to assess the impact of zinc (Zn), boron (B), and sulfur (S) on maize growth and yield. A single-factorial randomized complete block design (RCBD) was used with seven treatments and three replications. Results revealed that the combined application of micronutrients with the recommended dose of NPK significantly enhanced maize growth and yield parameters. The T6 treatment (Zn 10 kg/ha + B 6 kg/ha + S 7 kg/ha with recommended NPK) produced the highest values for key growth indicators: leaf area, ear length (19.56 cm), ear diameter (6.24 cm), kernel rows per ear (15.72), grains per row (44.25), ear weight (17.65 tons/ha), biological yield (34.80 tons/ha), grain yield (12.68 tons/ha), and stover yield (3.39 tons/ha). Additionally, T4 (S 40 kg/ha with NPK) resulted in the highest test weight (438.33 g). Micronutrient application did not significantly affect plant height or the number of leaves. The study concludes that applying 10 kg/ha of Zn, 6 kg/ha of B, and 7 kg/ha of S with NPK significantly improves maize yield, demonstrating suitability for the local soil conditions and offering a practical approach to mitigate hidden hunger in maize.

This study aimed to identify wheat genotypes tolerant to drought and terminal heat stress under late-sown conditions using stress tolerance indices. A field experiment was conducted with 18 genotypes, including checks, at the Directorate of Agricultural Research, Lumbini Province, Khajura, Banke. The trials were arranged in a randomized complete block design (RCBD) with three replications under two conditions: normal irrigated and simulated drought (via rainout shelter). Grain yield was recorded, and stress susceptibility and tolerance indices were estimated. The research showed that the average grain yield of all tested genotypes decreased by 58.8% under stress conditions   compared to normal irrigated condition . There was a highly significant difference (p<0.01) in grain yield across genotypes when grown under both irrigated and stress conditions. The genotype NL 1488 produced the highest grain yield of 3725 kg/ha, followed by Banganga (3693.67 kg/ha), NL 1447 (3550.33 kg/ha), NL 1423 (3454.67 kg/ha), NL 1444 (3426 kg/ha), and NL 1445 (3224.67 kg/ha) under normal irrigated conditions. Similarly, the genotype NL 1447 produced the highest grain yield of 1547.33 kg/ha, followed by NL 1415 (1541.67 kg/ha), NL 1444 (1442.33 kg/ha), NL 1345 (1349.33 kg/ha), NL 1446 (1338.33 kg/ha), and NL 1451 (1328.33 kg/ha) under drought conditions. The highest values of MP, GMP, and STI were obtained in genotype NL 1447, followed by NL 1444, NL 1415, NL 1451, and NL 1446. Thus, these genotypes exhibit high yield potential under both irrigated and drought conditions, making them suitable candidates for breeding programs aimed at improving drought resilience in wheat.
