METHODOLOGY FOR ASSESSING THE EFFECTIVENESS OF IMPLEMENTING THE POLICY OF INTERVENTION IN THE INTERNAL AFFAIRS OF THE STATE. PART 1.1. INDICATORS AND CRITERIA FOR ASSESSING THE IMPLEMENTATION OF THE POLICY OF INTERFERENCE IN THE INTERNAL AFFAIRS OF THE STATE (RESTRICTIONS OF INDEPENDENCE (SOVEREIGNTY), FREEDOM, RESTRAINING NORMAL POLITICAL DEVELOPMENT)
Authors:   Russian Presidential Academy of National Economy and Public Administration, Moscow, Russia, Gordienko Dmitry V.
Published: September 2024

The article substantiates the possibility of using indicators and criteria for assessing the implementation of the policy of intervention in the internal affairs of the state. The political guidelines of the Washington NATO summit determine the possibility of interference by NATO member states in the internal affairs of Russia, China, Belarus and other countries of the world. At the same time, NATO member states already use an extensive toolkit for interfering in the internal political affairs of foreign states. This makes it relevant to develop a Methodology for Assessing the Effectiveness of the Implementation of the Policy of Intervention in the Internal Affairs of a State. The indicators of the implementation of the policy of intervention in the internal affairs of a state may be: restrictions on its independence (sovereignty); restrictions on freedom; inhibition of normal political development; inhibition of normal economic development; inhibition of normal social development; as well as inhibition of the normal cultural development of this state. The criteria for assessing the implementation of the policy of intervention in the internal affairs of a state may include rules for assessing the values of such indicators in accordance with the implemented restrictions of its independence (sovereignty) and freedom; as well as inhibition of its normal political, eco-nomic, social and cultural development.

Authors:   Magnitogorsk State Conservatory (Academy) named after M. I. Glinka, Magnitogorsk, Chelyabinsk region, 455036, Russian Federation, Chernova Elena V.
Published: September 2024

The article analyses the emergence of a conservatory in the peripheral city of regional subordination from the perspective of the reasons and circumstances that determined this event. The topic of the “Magnitogorsk phenomenon” has been repeatedly raised and discussed in newspapers and magazines, in scientific articles and works of various levels, speeches at scientific conferences, etc. The most active discussions occurred in the second half of the 1990s during the period of the Conservatory’s formation, but gradually the interest in this problem decreased, only occasionally appearing as a statement of the uniqueness of the situation. The anniversary, celebrated in 2023 by the Magnitogorsk Conservatory, is an excellent occasion to analyse the objective and subjective factors that influenced the emergence of this phenomenon, especially since the past 30 years are an effective time corrector for evaluating the event. What factors turned out to be effective for the emergence of a music university in a peripheral industrial environment? The answer to this question, according to the author, should be sought in the history of cultural development of Magnitogorsk. It reflects the creative activity of the state, which provided the necessary socio-economic conditions, as well as of the teachers and musicians, who formed the traditions of professional art, contributing to the birth of the Magnitogorsk Conservatory.

Authors:   Russian State University named after A. N. Kosygin Institute “Maimonides Academy”, Moscow, 115035, Russian Federation, Yen Nguen Bao
Published: September 2024

The article is devoted to the description of the timbre of the soprano voice and its artistic semantics. It provides the definition of the term and a brief overview of the use of voice in operas by foreign composers. Technical fluency and mastery of the cantilena are put forward as essential properties of the voice. The article examines the coloristic features of the soprano voice, the repertoire for it, the connection of the voice with possible figurative interpretations and the emotional sphere. It is emphasised that the use of coloratura soprano is typical for European opera, while Russian composers prefer the properties of the lyrical timbre. It is noted that the vocal and aesthetic features of the coloratura soprano are suitable for the embodiment of fabulous images. The soprano is often the title character of the opera, the ideal image of a romantic heroine. The performer has to be fluent in singing technique and at the same time be able to creatively interpret a piece of music according to its style. The verbal text in opera is important, as it affects the formation of the musical fabric and can serve as an additional means of expression. In Russian musical art, soprano characters represent beautiful heroines of historical, epic, lyrical, comic, dramatic, psychological works.

Authors:   Russian State Specialized Academy of Arts, Moscow, 121165, Russian Federation, Nikodimov Igor Yu.
Published: September 2024

The use of artificial intelligence in inclusive arts education opens up new opportunities for learning and engaging all students, including those with special needs or disabilities. At the moment, adaptive tools are the most relevant. AI can offer adaptive tools and technologies to help students with various special needs participate in the artistic process. This article discusses the use of a tool such as Kandinsky for training the visually impaired and checking the level of elaboration and use of this software in image visualisation. In addition, the possibilities of the MidJourney software in implementing this software product in the educational process for visually impaired students are presented. The issue of “unambiguity” of visual images is considered, i.e. whether neural network can produce an authentic image obtained at the first request if a similar request is received several times and at different times? A comparative analysis of neural network data is carried out according to two criteria: technical excellence (to what extent the program contributes to the image visualization required by students) and “interface friendliness” (how easy and understandable it is for the student to work with this program).

Published: September 2024

Cervical cancer (CC) is a global public health problem. Epigenetic factors, such as microRNAs, play a key role in the development of CC. Although a previous study reported that miR-381-3p inhibits CC by downregulating fibroblast growth factor 7, its role in CC remains largely unknown. This study aimed to fill the gap by analyzing the role of miR-381-3p in CC. Expression analysis was performed using databases including The Cancer Genome Atlas, Gene Expression Omnibus, and the Human Protein Atlas. Receiver operating characteristics and Kaplan–Meier curves were plotted using GraphPad Prism and Kaplan–Meier Plotter databases. Target messenger RNAs were identified using the miRDB and miRPathDB databases. Kyoto Encyclopedia of Genes and Genomes, Gene Ontology Biological Process, and Gene Set Enrichment Analysis were performed using Enrichr and WebGestalt databases. Mutation analysis was conducted using the cBioPortal database. In this study, we found that miR-381-3p expression is low in CC. Moreover, we identified a total of 1,191 potential targets of miR-381-3p that may be involved in key signaling pathways in this cancer. Interestingly, our results identified ten-eleven translocation 3 (TET3) as a potential target, with evidence suggesting that TET3 expression is increased in CC. This increase in TET3 expression may be useful as a diagnostic and prognostic biomarker. In addition, four mutations were identified in the TET3 protein. TET3 expression increases in patients with International federation of gynecology and obstetrics stage II CC and in those with lymph node metastasis. Mechanistically, TET3 expression may be induced by a gain in copy number, human papillomavirus infection, aberrant methylation, and activation of the transcription factor activator protein 2α. Finally, we identified 145 genes that are regulated by TET3 in CC, which are involved in key pathways and biological processes associated with CC, such as the cell cycle, DNA replication, mitogen-activated protein kinase signaling pathway, and basal transcription factors. In conclusion, we identified the miR-381-3p/TET3 axis as a key player in the carcinogenic process of CC.
Ocular changes in Alzheimer’s disease
Authors: Hamilton Trinita Jude , Kalisch Bettina E.
Published: September 2024

Alzheimer’s disease (AD) is an incurable, irreversible condition that bears a large global burden. An early diagnosis is imperative to allow the maximum time for treatment interventions. The eye’s involvement has been identified in AD, making it a promising option for a non-invasive early diagnostic and screening tool. The pathology of AD observed in the brain such as amyloid beta (Aβ) plaques and phosphorylated tau have been mirrored in the retina. There is also evidence that AD pathology in the retina precedes the onset of symptoms and the deposition of plaques in the brain. It is estimated that Aβ burden results in structural changes in the eye such as degeneration of the retinal nerve fiber layer, thinning of the macula, reduced blood flow rate, and thinning of the choroid. These structural changes can be observed using non-invasive imaging techniques such as optical coherence tomography. This review examines the existing literature on AD pathology in the retina and discusses the possibility of using retinal imaging techniques to screen for AD.
Exercise and frailty in later life: A systematic review and bibliometric analysis of research themes and scientific collaborations
Authors: Azizan Azliyana
Published: September 2024

Exercise is a promising intervention for frailty, but optimal protocols and implementation approaches remain unclear. In this review, a bibliometric analysis was conducted to synthesize research growth, collaborations, intellectual structure, and gaps in the literature on frailty and exercise over the past two decades. The Web of Science and Scopus databases were searched for relevant publications from 1987 – 2024. The bibliometric analysis examined publication trends over time, contributing countries, institutions, authors, journals, research themes and hotspots, collaboration patterns, and evidence gaps. Data visualization and mapping were conducted using VOSviewer, Biblioshiny, and ScientoPy. A total of 447 publications were included in the analysis. The results indicate that research output has grown rapidly since 2010, led by the United States of America (USA), China, Japan, Spain, and Italy. The University of Valencia (n = 12) and the School of Medicine, USA (n = 11) were the most prolific institutions. Five key research clusters were identified through keyword analysis: (i) Frailty assessment, (ii) clinical trials, (iii) cognition, (iv) exercise protocols, and (v) physical outcomes. Regional collaborations were prominent between European, North American, and East Asia-Pacific countries. The bibliometric analysis revealed a surge in publications, with research concentrated in a few productive hubs. There is potential for newer institutions to emerge through international collaborations. Addressing gaps in qualitative, psychosocial, economic, implementation, and translational research could accelerate the translation of evidence into policy and practice. Continued knowledge sharing and partnerships focused on priority gaps can optimize exercise interventions amidst global population aging. This review synthesized the growth, collaborative landscape, and intellectual structure of research on frailty and exercise over nearly four decades. The findings provide insights to inform future research directions and facilitate the translation of evidence into optimized exercise protocols that can be implemented at scale to benefit frail older adults.
ANALYSIS OF ROTARY MOWER DESIGNS – CONDITIONERS
Authors: KONDRATUK Dmytro , TRUKHANSKA Olena , PRIADKIN Maksym
Published: September 2024

An integral operation of any technology of harvesting hay is mowing the grass, the quality of which depends on the collection of hay from a unit of area, as well as the growth of grass and the yield of grass in the following years. Modern rotary mowers are able to cut grass with high quality, regardless of the state of the stem. The main types of rotary mowers are disc and drum. Their productivity is 20-30% higher than the productivity of segment-finger mowers. The quality of hay largely depends on the drying speed of the vegetative organs of the mown plants. In order to equalize the drying speed of grass stems and leaves, rotary mowers are equipped with roller or impact (conditioners) flattening devices. The quality of grass flattening is affected by the material from which the rollers are made and the shape of their surface. With the same profile of the surface of the rollers, the efficiency of flattening with steel rollers is higher than with those covered with polymer materials. However, their work is accompanied by increased mechanical losses due to leaf breakage. In order to make the flattening rollers work smoother, rubber or polyurethane is applied to their surface. Fluted rollers flatten the grass more intensively than smooth rollers. Roller flatteners provide high-quality work when a layer of grass of uniform thickness is fed into the gap between the rollers.
On the contrary, the number of unflattened stems increases. Roller-type tedders are less harsh on the grass than dynamic tedders, therefore, in order to reduce losses from breaking off leaves and inflorescences, they are recommended for working with leguminous grasses. Since the flattening devices of dynamic action are less sensitive to the unevenness of the mass supply, it is advisable to use them when mowing grasses with an uneven density of grass and cereal grasses.
CONCEPT OF IMPLEMENTATION OF PRECISION MICROPROCESSOR CONTROL SYSTEM OF COLLECTOR ENGINE OF CNC MACHINE
Authors: HRANIAK Valerii , ROHACH Valentyn
Published: September 2024

An emerging trend in recent decades is the increasing role of CNC equipment, which has already become one of the main types of equipment in significant portions of modern technological lines. This is attributed to both the complication of technological processes and the rising demands for product quality, as well as the increased productivity and functionality of modern microprocessor systems. It is worth noting that the DC motor and its electric drive, which can operate on both direct and alternating current, occupy a significant niche in the social production system and deserve special attention.
One of the key features of modern scientific and technological progress is the wide use of microelectronics in various branches of the national economy, which is constantly growing. The role of microelectronics in the development of social production is determined by its versatile capabilities in solving various tasks and its deep influence on culture and everyday life of a person.
Currently, special attention is focused on the introduction of microprocessors that solve the tasks of automating the control of mechanisms, devices and equipment. Adaptation of microprocessors to specific tasks is usually carried out by developing appropriate software, which is then loaded into the device's memory. Hardware adaptation, in most cases, is carried out by connecting the necessary integrated circuits and organizing input-output corresponding to the problem being solved. These characteristics ensure high flexibility of such systems, which allows you to quickly adapt production equipment to new technological conditions.
The article proposes a concept for implementing a precision microprocessor control system for a CNC machine's DC motor, implemented on the basis of single-chip microcomputers, characterized by increased reliability due to the reduction in the number of serial links. A methodology for implementing a precision microprocessor control system for a CNC machine's DC motor has also been developed, the application of which will significantly simplify the design process and reduce the time required to build such a system.

Published: September 2024

This paper investigated a precise algorithm combining X-ray Fluorescence and Neural Network (XRF-NN) for predicting ash content. The 261 sets of XRF tests show that the 34 elements in the chosen Guqiao coal can be categorized as major, secondary and tiny elements, whose cumulative ratio were ~95%, 4-5% and <1%, respectively. Referring to the machine learning theory, the construction strategy of Element-Ash dataset was determined viz. value determination → standardization → division → optimization of generalization ability. Then, the hyperparameters optimization displays that XRF-NN model with 34 inputs and 1 output was suitable to predict coal ash content, where the activation function, loss function, and optimizer were ReLU, MAE, and Momentum, respectively. After iterative training, the new XRF-NN model provides the precise prediction of coal ash content with the absolute errors between -2.0% and 2%. Moreover, the prediction accuracy rose from 57.69% to 100%, as the expected relative error increased from 1% to 5%. Furthermore, the comparisons between different prediction methods reveal that the minimum MRE of 1.22% can be obtained by XRF-NN with total elements, which was only half of those given by the conventional Multiple Linear Regression and Partial Least Squares Regression. Besides, XRF-NN model presents the root mean squared error 0.797%, the mean absolute error 0.625% and the coefficient of determination 0.999, which were significantly superior to those calculated by Dual-Energy Gamma-ray Transmission, Ploy, RFR, XGBoost and DNN model. The results of this study suggest the excellent performance of the new XRF-NN model in predicting ash content.
Selecting the best-value biosimilar in emerging countries
Authors: Castañeda-Hernández Gilberto
Published: September 2024

The aim of biosimilars is to alleviate the financial burden of biological medicinal products. A most relevant challenge for emerging countries is how to select the best option available. In most cases, price is the major determinant, as budgets are chronically scarce. However, initial savings due to price reductions can be overridden if there is a lack of supply due to product shortages or withdrawals. These events can be prevented by a best-value strategy. According to the concept of best-value medicinal products, price is only one of the various criteria to be considered. The purpose of the present paper is to provide suggestions of criteria that can be useful for selecting the best-value biological in emerging countries. Six criteria, that are not limitative, have been selected as follows: standards of regulatory approval, quality of the product, good distribution practices, security of supply, pharmacovigilance, and price.

Exploring the Factors Behind Romantic Relationship Conflicts Among University Students: A Case of Mukuba University
Authors: Chanda Lazarous
Published: September 2024

The study sought to investigate the factors behind romantic relationship conflicts among university students. This was a case study conducted at Mukuba University. The target population was undergraduate students at Mukuba University. The sample was selected using quota sampling technique; thus, participants were selected from different schools and year of study based on their romantic relationship status. Those who had not experience romantic relationships were not part of the study. The sample size of the study was 15 students drawn from three schools. The data were collected using face-to-face interviews with the selected students.  The study identified six overarching themes, including communication issues, insecurity, time management and priorities, intimacy and sexual matters, financial issues, and cultural or religious disparities as the causes and types of conflicts. The study also revealed that communication conflicts stem from partners ignoring, providing the silent treatment, or encountering communication ambiguity. Insecurity issues arise from incidents of infidelity, suspicion, and possessiveness, while time and priority conflicts result from imbalances between academic commitments and the partners' quality time together. Moreover, the study sheds light on conflicts related to differences in sexual desires and financial discrepancies. Financial challenges include concerns about overdependence on partners for support or materialistic attitudes, often leading to conflicts. Religious and cultural disparities are also influential, as participants experienced relationship strain due to differing beliefs. Furthermore, the investigation explored the outcomes of these conflicts, categorizing them into emotional, relational, academic, mental health, and social impacts. Conflicts triggered anxiety, depression, and stress, affecting relationship stability and leading to decreased feelings of love and connection, breakup, or relationship resilience. Additionally, conflicts negatively affected academic performance and concentration, leading to stress-related physical symptoms and social isolation among individuals experiencing relationship conflicts. The coping mechanisms employed by individuals were categorized into maladaptive strategies like abuse or escapism and adaptive strategies such as seeking support and self-care/stress management. Maladaptive strategies involved aggressive behaviors and avoidance, while adaptive mechanisms included seeking external support or engaging in self-care activities as a means to manage conflict-induced stress. This study contributes to the understanding of conflicts in romantic relationships, emphasizing the complexity and diverse impact of these conflicts on individuals involved.

Authors: Onuoha D. C. , Odo C. C , Danjuma D , Okolie U. C
Published: September 2024

This study examined the environmental effects of oil spillage in Nembe, Bayelsa State by determining the particle size distribution of the soil, determining the nutrients composition of the soil contaminated with oil spill and the soil of a nearby control site in the study area, comparing the composition of the soil from the polluted site and that from the control site, and comparing the heavy metal present in the polluted soil in the study area with the NESREA standards. The study adopted laboratory research design in generating data for the analyses. Ten samples each were collected from two communities in Nembe, Okoroba and Etieme both from top soils and at depth. From the analyses it was found that there is a slight but insignificant variation on the pH of the soils, which averaged from the (top soil) 6.12 and 5.73 for the control Etieme and the affected soil of Okoroba respectively. The soils are all slightly acidic and this acidity cannot be attributed entirely to the oil spill since the control is equally acidic. Soil gotten from the top at Okoroba had a loamy sand (LS) texture. This has a a high proportion of sand, while the sub soil gotten from the same location had a silt loam (SL) texture, with a balanced mixture of s and, silt and clay. Soil gotten from the top at Etieme had a silt loam texture while the subsoil had a silt clay loam texture(SCL), which contain a high proportion of clay compared to sand and silt.  This fraction averaged 66.72% in Etieme soil and 76.72% in Okoroba soil while clay decreased from 21% in Etieme to 16.70 in Okoroba. From the test of hypothesis, it was found that the oil spill concentration of the soil in the polluted site and the soil in the control site are not significantly different from each other; also the heavy metal concentration of the soil in the polluted site did not significantly deviate from the NESREA standards. Nevertheless, it should be known that heavy metals have the ability to bio-accumulate and biomagnify, hence the metal concentrations of this site will come to deviate from that of the NESREA standards over time if precautionary measures are not taken. It was also confirmed that oil spill has detrimental effect on both man and his environment. Comparison of the analytical data gotten from the polluted soil with the data gotten from the control nearby soil shows that there was no significant difference between the soil nutrient in the polluted site and the soil in the control site. The study therefore concluded that effect of oil spill on land as an aspect of the environment in Nembe is still minimal hence the need to urgently tackle the problem of oil spill was recommended so as to nip these negative effects by the bud before it goes out of hand.

One of the main challenges in the supplements and food industry is maintaining the oxidative stability of Omega-3 rich oils, which are highly susceptible to oxidation. The oxidation of these oils not only affects their quality and flavor but can also diminish their health benefits, such as reducing inflammation and supporting brain function. This study evaluates the oxidative stability of Omega-3 oil using electrochemical impedance spectroscopy (EIS), a technique that offers a faster and non-destructive alternative compared to traditional chemical methods. Oil samples were subjected to autoxidation at room temperature and analyzed over a frequency range of 3 kHz to 100 kHz, while peroxide levels were measured using traditional bromatological techniques for comparison. The results revealed a strong linear correlation (R² = 0.99) between peroxide levels and imaginary dielectric permittivity, highlighting the potential of EIS to effectively characterize the oxidative stability of Omega-3 oil. This finding is significant because EIS allows for faster and non-destructive evaluation, facilitating real-time monitoring of oxidation in Omega-3 oils, which could be particularly beneficial for manufacturers seeking to ensure the quality of their products more efficiently. Additionally, the use of EIS can reduce costs and analysis times, improving the efficiency of quality control processes. However, possible disadvantages include the need for specialized equipment and precise calibration of the method for different types of oils. Future research should focus on further optimizing and validating this method under different storage and processing conditions, as well as exploring its applicability to other types of edible oils and Omega-3 derived products to ensure their quality and safety. Moreover, it would be beneficial to investigate the integration of EIS into automated production lines for continuous monitoring, which could revolutionize the way Omega-3 oil quality is assured in the industry.

Antecedentes: Durante diciembre del año 2019 se generó un brote de un nuevo virus responsable de cuadros respiratorios severos en la ciudad de Wuhan, China. El agente patológico que genera estos cuadros clínicos de neumonía resultó ser un virus de la familia Coronaviridae con un gran parecido al Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV). Objetivo: Determinar la asociación entre Hipertensión Arterial Sistémica y mortalidad por COVID 19 en el HGZMF N.16 Cuauhtémoc, Chihuahua. Material y métodos: Estudio analítico, transversal, retrospectivo. Se analizaron expedientes de pacientes que fallecieron por COVID 19 del 01 de enero al 31 de diciembre del 2021 realizando comparativo entre pacientes que tenían hipertensión y que no tenían hipertensión, identificando la existencia o inexistencia de relación entre las variables propuestas. Resultados: Se analizaron 122 expedientes de defunciones por COVID 19 encontrando que la hipertensión arterial actúa como factor de riesgo al elevar 2.03 veces más la probabilidad de morir por COVID 19 (OR=2.03., IC:95% =1.38-2.99., p= <0.05) y una tasa de mortalidad por COVID-19 del 16.05%. Conclusiones: Existe asociación de la hipertensión arterial sistémica como factor de riesgo para la mortalidad en COVID 19.

El caso práctico presentado en el documento trata sobre el diseño de un prototipo de hormigón permeable para áreas recreativas en la Universidad Estatal de Milagro (UNEMI). El objetivo principal es evaluar la viabilidad técnica, económica y ambiental de este material como una solución sostenible para el manejo de aguas pluviales en el campus universitario. El hormigón permeable se destaca por su capacidad para permitir el paso del agua a través de su superficie, lo que ayuda a controlar la escorrentía superficial, previniendo inundaciones y mejorando la infiltración de agua en el suelo. Esta tecnología no solo es beneficiosa desde el punto de vista medioambiental, sino que también contribuye a la creación de espacios verdes, promoviendo un entorno urbano más sostenible y resiliente. El proyecto incluye la elaboración de encuestas para evaluar la aceptación del hormigón permeable, la realización de pruebas de permeabilidad, y un análisis costo-beneficio en comparación con el hormigón convencional. Los resultados obtenidos ayudarán a determinar la eficacia del hormigón permeable y su potencial implementación a mayor escala en la universidad, incentivando el desarrollo de investigaciones futuras en el área.
