Authors: Lin Xiaoming , Bu Cuiping , Su Jiangling
Published: December 2023

Stomatitis or generalized inflammation of the mouth includes inflammation or pain in the mouth. Natural compounds are one of the best options for stomatitis treatment. Silybum marianum has many medicinal properties in traditional medicine. In recent research, iron nanoparticles were formulated by S. marianum. The research aim was to determine the Fe nanoparticles’ (FeNPs) efficacy in denture stomatitis treatment. FeNPs were characterized by TEM, FE-SEM, and UV-Visible. This was a clinical trial study with 60 patients who received FeNPs. The patients in 14 days were suggested to use mouthwash 1 time per 6 h each time 15–20 drops for 120–180 s and after that they should avoid drinking and eating for 0.5 h; patients in the two groups were offered to apply the drug. At each visit, mycological samples were taken for culture from the palatal mucosa. Inflammation amount and erythema were determined in each session and determined with a graded blade and recorded. The erythema surface of the palatal was significantly decreased in the group at follow-up visits compared to the pretreatment condition.

Published: December 2023

This research investigates the dynamic interplay between land use changes and landscape ecological risks in China’s Jiangsu Province, specifically focusing on the Huai River-Gaoyou Lake region. Leveraging multi-temporal remote sensing data from 2000 to 2020, we conducted a comprehensive analysis of shifting land cover patterns and their implications. Employing geostatistical techniques, we developed a landscape ecological risk assessment model to quantify ecological vulnerabilities. Additionally, we conducted a resident satisfaction survey aligned with the “Production–Living–Ecological” framework to gain insights into societal perceptions of land use dynamics. Our findings reveal significant land use shifts driven by urbanization, industrialization, and agricultural modernization. While farmland areas have decreased, water bodies and artificial surfaces have expanded, reflecting societal demands and economic growth. The landscape ecological risk assessment model highlights localized vulnerabilities, emphasizing the intricate relationship between land use changes and ecological risks. The resident satisfaction survey indicates overall contentment with various aspects of land use, especially in terms of residential comfort and transportation convenience. However, ecological concerns underscore the need for a balanced approach to land management that prioritizes ecological sustainability alongside economic development.

The quest for the ideal business translator profile in the Romanian context
Authors: Duță Oana Adriana , Popescu Cecilia Mihaela
Published: December 2023

An ideal translator profile is a crucial issue for both translation providers, who want to deliver impeccable performance, and translation beneficiaries, whose purpose is to obtain flawless services. In the context of Romanian higher education, two distinct educational profiles of providers are distinguished in the business translation market: graduates of Philology, who have been trained in translation (3-year BA and 2-year MA programmes in Translation Studies), and graduates of Faculties of Economics or Business who have undertaken 3-year and/or 2-year MA study programmes in a foreign language. Showing the results of a study conducted with groups of third year Bachelor students of the University of Craiova, Romania (students in Translation Studies and students in the Finance and Banking English-taught programme), across a 3-year period (2015–2017), our research aims at providing answers to the following questions: To what extent does each of these two profiles match the ideal one of a business translator? What are the strengths and weaknesses of each of the two training profiles? What specific actions can and should be taken for each of the two target groups in terms of university training?

Authors: Özden Selin
Published: December 2023

The surface soil samples were collected from Northwest Turkey. The activity concentrations of 226Ra, 232Th, and 40K were measured using an HPGe gamma-spectroscopy system. The activity concentrations of 226Ra, 232Th, and 40K in the soils were found to be in the range of 11.78 ± 1.12–43.89 ± 14.94, 3.19 ± 2.01–88.22 ± 0.92, 362.81 ± 5.94–829.27 ± 12.38 Bq kg−1 d.w., respectively. The Surfer program was used to obtain 3-dimensional maps of the specific activities. Radium Equivalent Activity (Raeq), Absorbed Gamma Dose Rate (D), Annual Effective Dose Equivalent (AEDE), The Excess Life Time Cancer Risk (ELCR), External (H
ex) and Internal (H
in) Hazard Indexes, Annual Gonadal Dose Equivalent (AGDE), and Activity Utilization Index (AUI) were calculated and compared with the recommended values. Pearson’s correlation analysis (PCA) and factor analysis (FA) were utilized to analyze the data and indicate between the radiological parameters. The analysis showed that the total radiation was mainly caused by 226Ra and 232Th.
The impact of narration, sentiment, and emotional modulation on economic of decision-making: a multidisciplinary study
Authors: Zubiel Magdalena , Waligórska Hanna
Published: December 2023

The article delves into the interplay between narration, sentiment, and decision-making processes, particularly within the realm of economic choices. Emphasizing the pivotal role of message content, the authors present a hypothesis depicting the profound impact of narration, characters, and sentiment in the communication process. These components wield significant influence over the emotional facets of decision-making, influencing the process or prompting alterations to initial decisions. Critically challenging established economic paradigms, the article underscores the indispensable emotional dimension inherent in communication. Drawing upon the scholarly contributions of eminent figures like Robert J. Shiller, the authors synthesize insights from psychology and neurobiology, unraveling the manipulative essence inherent in narration. In the theoretical section, the article also references Uri Hasson's theories and research on brain synchronization during the communication process. The practical segment of the article substantiates these claims through the presentation of findings from neuropsychological studies. The study confirms the hypothesis that narratives infused with high sentiment resulting from emotional interactions, following a cause-and-effect structure with a visible beginning, development, and end, lead to better synchronization and intensify neuronal responses. The structure, plot shaping, and sentiment in messages, influenced by word choice, shape narrative economy and impact cognitive costs in decision-making. The obtained results confirm that precisely tailored narration effectively reduces cognitive costs associated with the decision-making process. This validates the authors' hypothesis, opening up space for research replication and falsification of the results obtained.

The changes in the electronic subsystem of a porous carbon material caused by its doping with Mn, Cr, and Fe and laser irradiation were studied by the method of electron paramagnetic resonance. It has been found that Mn doping leads to the appearance of several paramagnetic centers, and laser irradiation facilitates the redistribution of electrons between different states so that their mobility increases due to the transition from the g = 3.9 to the g = 6.0 state. The Mössbauer spectroscopy of porous Fe-doped carbon material indicates the presence of oxygen ligands for iron ions, in particular the formation of octa- and tetra-complexes with redistribution of electron density between iron and oxygen nuclei, and, accordingly, changes in the degree of covalence of the chemical bond from Fe3+ to Fe2+.

LA CUESTIÓN SOCIOAMBIENTAL EN COMUNIDADES TRADICIONALES DE FAXINAIS EN PARANÁ, BRASIL: REFLEXIONES SOBRE UNA PEDAGOGÍA HOLÍSTICA E INTEGRATIVA
Authors: Löwen Sahr Cicilian Luiza
Published: December 2023

La cuestión socioambiental viene siendo ampliamente discutida en la actualidad. Se busca superar la relación dicotómica entre sociedad y naturaleza. Nuevas ideas vienen surgiendo a partir de la concepción de una sociedad humana integrada, y no opuesta, a la naturaleza. Es en este contexto que se asiste a una revalorización de sociedades donde la “unión de lo real” se vuelve evidente. Este es el caso de los pueblos y comunidades tradicionales brasileños, que precariamente se han integrado al capitalismo moderno. Como reflejo de ese momento, se torna necesario pensar en una trasposición de la concepción holística e integrada de la cuestión socioambiental para la enseñanza. En este sentido, este artículo presenta una reflexión sobre nuevos caminos pedagógicos a partir de uma investigación de la formación socioambiental de comunidades tradicionales en Paraná: los Faxinais. Se piensa que estas comunidades pueden representar más que simples ambientes de enseñanza-vivencia para los propios alumnos-moradores. Los Faxinais presentan elementos de gran valor para pensar em uma pedagogía holística em función de su gran diversidad y capacidad ecológica, sus formas sociales integradas, su producción econômica no-capitalista y su enraizamiento cultural.

Authors: Huepe Gabriela , Cornejo Guerrero María Constanza
Published: December 2023

Este trabajo se basa en la lógica factual como sustento teórico-metodológico para analizar los argumentos incluidos en las opiniones sobre la pandemia del COVID-19 por parte de venezolanos y chilenos de las regiones Metropolitana y Biobío de Chile en el 2020. Sobre un total de 65 entrevistas cualitativas, se analizó la presencia y estructura de los argumentos según el modelo de Toulmin, mostrando que su forma básica, datos más conclusión, es lo que caracteriza a esta muestra, al igual que el campo argumentativo de la experiencia como el lugar de donde asuntos de salud pública y economía se integran en el lenguaje cotidiano. El análisis de contenido de las opiniones muestra como principal tema el impacto negativo de la pandemia, donde la migración emerge como factor que agrava o mitiga su impacto en Chile. En futuras investigaciones cualitativas en salud, utilizar enfoques que se ocupen del razonamiento a la base del comportamiento de las personas y comunidades, puede ser de gran utilidad por aportar información profunda, rica y culturalmente pertinente.
Sobre el concepto de suficiencia en la argumentación derrotable
Authors: Ihnen Jory Constanza
Published: December 2023

El propósito de este artículo es elaborar un concepto de suficiencia que tome en cuenta la naturaleza derrotable de buena parte de los argumentos que empleamos en nuestras discusiones cotidianas, y que a su vez sea útil para evaluarlos en la práctica. Con este fin se revisan definiciones propuestas por diversas teorías de la argumentación de orientación lógica, retórica y dialéctica, para luego proponer una definición que integra coherentemente elementos de las distintas aproximaciones. Esta definición es seguidamente complementada con una especificación del  significado de los términos clave que la componen, con el objetivo de dar respuesta a tres preguntas que han estado al centro del debate sobre la suficiencia: ¿qué tipo de impugnaciones puede formular la contraparte a la inferencia de una argumentación derrotable?; ¿qué deberíamos entender por “la contraparte” en una discusión dada?; y ¿qué significa hacerse cargo de esas impugnaciones de manera exitosa?

Authors: Veloso Gabriela , Ferreira Roberta , Roberto Wanderley , da Silva Sidney Nicodemos
Published: December 2023

The combinated therapy for cancer treatment aims to use methods that act through different mechanisms, reducing the probability of developing resistant cancer cells and intolerable side effects. The Magnetic hyperthermia is a modern, directional, and minimally invasive technique that is based on increasing the temperature of tumor cells by means of heat dissipated by particles (subjected) to an alternating magnetic field. Brachytherapy is an oncological treatment where a radioactive source is placed in or near the tumor area for localized treatment of the tumor cells. In this work, silica particles containing iron oxide and samarium (Si-Mag-Sm) were produced by the Sol-Gel method to act as agents for the combined treatment of cancer by hyperthermia and brachytherapy. The iron oxides were characterized by Mössbauer, Zeta Potential, TEM and SEM, and magnetization measurements. The samples were characterized by FTIR, DRX, FRX and TG. The radioactive activity of the elements was estimated by a theoretical dosimetric calculation. XRD, FTIR and XRF techniques indicated synthesis of silica containing samarium and iron oxide. TG indicated loss of adsorbed water between 25 and 150°C, elimination of nitrates and condensation reactions between 160 and 700°C and residual mass of 90%. The dosimetric calculation outlined relevant activity for 153Sm, being higher than the other elements. The morphology of the natural iron oxide observed by TEM showed properties suitable for use in cancer treatment. The Zeta potential showed that the iron oxide has excellent suspension properties for in vivo applications and by the Mössbauer technique, the iron oxide showed superparamagnetic behavior at room temperature.
Metallurgical aspects of dispersion nitride hardening of high-carbon steel. Message 1. The effect of austenizing heating and tempering parameters on the phase redistribution of nitrogen and vanadium in steels

Published: December 2023

Systemic fundamental research for several decades at the FTIMS of the National Academy of Sciences of Ukraine and the accumulated experience of industrial application have shown that the technology of dispersion nitride hardening, which is based on the alloying of steels with nitrogen and vanadium, is a method of significantly improving the entire complex of physical, mechanical and operational properties of cast and deformed carbon, low-alloy and alloy steels of various functional purposes. The most significant advantage of the steels developed at the FTIMS of the National Academy of Sciences of Ukraine is a simultaneous significant increase in their static and cyclic strength, fracture toughness, thermal strength and heat resistance, wear resistance, annealing, weldability, reduction or complete elimination of the tendency to natural, deformation and warm embrittlement. Medium- and high-carbon pre-eutectoid and eutectoid steels of high strength and wear resistance are widely used in various fields of mechanical engineering. However, they are most widely used for railway wheels and rails. The reliability and operational resource of wheels and rails, which are in extremely harsh operating conditions, mainly determine the technical and economic performance indicators of railway transport. At the same time, existing relatively cheap non-alloyed and low-alloyed medium- and high-carbon wheel and rail steels no longer meet the modern requirements of increased speeds and load capacity of rolling stock. Keywords: carbon steels, dispersion nitride hardening, austenization, tempering, phase redistribution of nitrogen and vanadium.

Published: December 2023

Suicide is the second leading cause of death for 10- to 24-year-olds in the United States and is a global public health issue, with a recent declaration of a National State of Emergency in Children’s Mental Health by the American Academy of Pediatrics, American Academy of Child and Adolescent Psychiatry, and Children’s Hospital Association. This clinical report is an update to the previous American Academy of Pediatrics clinical report, “Suicide and Suicide Attempts in Adolescents.” Because pediatricians and pediatric health care providers are at the front line of care for adolescents amid a child and adolescent mental health crisis, and because of the chronic and severe shortage of mental health specialists, it is important that pediatric health care providers become facile with recognizing risk factors associated with suicidality and at-risk populations, screening and further assessment of suicidality as indicated, and evidence-based interventions for patients with suicidal ideation and associated behaviors. Suicide risk can be mitigated by appropriate screening, bolstering of protective factors, indicated treatment, community resources, and referrals to mental health providers when available.
Trophic morphology and diet of the endangered fish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae).
Authors: Domínguez-Cisneros Sara Elizabeth , Kobelkowsky Abraham , Velázquez-Velázquez Ernesto
Published: December 2023

Introduction: Tlaloc hildebrandi is a freshwater killifish, endemic to southern Mexico and under threat of extinction; the knowledge of the trophic morphology and diet is needed by conservation managers. Objective: To analyse and describe the anatomy of the visceral skeleton, visceral musculature, digestive tract and its adjoining glands; as well as the diet.  Methods: The trophic anatomy was performed on 20 adult specimens of both sexes, through the manual dissection; and stomach contents analysis was performed in 60 individuals to describe the diet. Results: As notable characters of the visceral skeleton of T. hildebrandi we found the posterior notch of the premaxillary, the presence of the “coronoid cartilage”, the tricuspid shape of the gill rakers of the first branchial arch, and the presence of the splenial bone; some outstanding characters of the visceral musculature are the origin of the retractor dorsalis muscle from the first four vertebral centra, and the division of the pharyngoclavicularis externus muscle into two sections (A and B). The notable characters of the digestive tube are the absence of stomach and pyloric caeca, and the presence of the “intestinal valve”. The insects of the Chironomidae family (53% IVIr) were the dominant item in the diet of the Tlaloc hildebrandi. Conclusions: The organization of the digestive system of T. hildebrandi corresponds to the general morphologic pattern of the Cyprinodontiformes; however, we register as new information for fish, the presence of the “coronoid cartilage” and the “intestinal valve”. The structures of the trophic morphology and the components of the diet, confirm us that T. hildebrandi is a carnivorous-insectivorous fish.
Evaluating the economic freedom of countries: An application of grey factor analysis
Authors: Koçak Deniz , Çalişkan Abdulkerim
Published: December 2023

Economic freedom is crucial in determining policies for economic performance of nations and monitoring changes in the international economic order. Evaluating economic freedom requires the use of multiple indicators related to each other. Traditional statistical analyses used as an evaluation tool are often constrained by the probability distribution of indicators or sample size. To overcome these shortcomings, this paper uses grey factor analysis (GFA) to evaluate the economic freedom of countries. GFA can be used with multiple interrelated indicators without requirements about the probability distributions or sample size. The absolute degree of grey incidence matrix is used instead of the correlation matrix in factor analysis and GFA integrates the advantages of grey system theory into factor analysis. The analysis covers data for 2010 and 2020 about 20 economic freedom indicators in 36 selected countries. Two factors explain a significant part of the variance for both years. The scores for countries were obtained using the explained variance ratio as a weight. Our results show that GFA provides more accurate results than traditional statistical analyses.
An investigation of the influencing factors of value added tax collection effectiveness in EU Member States
Authors: Králik Lóránd-István , Szász Erzsébet
Published: December 2023

Tax evasion is reducing the revenues of public budgets of many European Union (EU) Member States (MS). To improve the effectiveness of tax collection, during the last decade authorities in several MS have taken measures to reduce the value added tax (VAT) gap (i.e., revenue received as a percentage of theoretical liability). In the Central and Eastern European region, VAT gap reduction measures have been implemented effectively in Hungary and Poland, whereas in Romania the effectiveness of these measures is very low: Romania has been the worst-performing EU MS in collecting VAT for more than 10 years. Our study analyses the factors influencing this VAT gap. Our analysis relied mainly on a fixed effects panel regression model, using for a balanced panel an individual and time fixed-effects with cluster-robust standard errors model, and for the unbalanced panel the fixed-effects regression with individual-specific slopes. Our results show that the size of the VAT gap is primarily influenced by five variables: the transparency index, the tax collection ratio, the law enforcement index, the VAT revenues ratio and the digitisation index.

Authors:   Volgograd State University, Movchan Denis , Boroznina Natalia ,   Volgograd State University, Tkachev Alexander ,   Tambov State Technical University
Published: December 2023

Many industrial sectors require efficient heat transfer to ensure safe and efficient operation of equipment. Thermal pastes are materials used to improve heat transfer between different surfaces. Recently, carbon nanotubes (CNTs) have become widely used in the field of electronics and microelectronics due to their unique physical and chemical properties. One of the areas where CNTs can be applied is thermal conductivity. In this study, the effect of carbon nanotubes on the thermal conductive properties of thermal pastes was investigated. In this paper, an experiment was conducted to evaluate the thermal stability and performance improvement of thermal pastes by adding carbon nanotubes. KPT-8 thermal paste with a density of 2.6 g/cm2 and thermal conductivity of 0.7 W/mK was used in the experiment. Thermal pastes are materials used to improve heat transfer between different surfaces. The results of the study showed that thermal paste with CNT additives has higher thermal conductivity than thermal paste without additives. This indicates that CNTs can be effectively used as additives to improve the thermal conductivity of thermal pastes. But when CNTs are used as additives in thermal pastes, certain problems may arise, such as the grouping of CNTs in the mass of the substance. This can lead to an uneven distribution of CNTs in the thermal paste and, as a consequence, to inhomogeneous thermal conductivity. The results emphasize the potential of carbon nanotubes as a promising additive for improving the thermal conductive properties of thermal pastes in various applications.

Recently, more and more people have become aware of the need to protect the environment and find new ways to protect our planet from various types of pollution. In this regard, science and technology play an important role in finding new solutions to protect the environment. One innovative development is boron-carbon nanotubes, which contain equal amounts of boron and carbon atoms. Modification of such nanotubes with an amine group would allow to use them for creation of highly sensitive sensor devices, which would help to control the levels of lithium, sodium, potassium in the environment and prevent their negative impact on nature and human health. In this article, a theoretical study of the sensing properties of a functionalized amino-group boron-carbon nanotube of the zig-zag type (6.0) containing equal amounts of carbon and boron is discussed. Such a nanotube could act as an element of a sensor device for environmental protection. The simulation was performed within a molecular cluster model using the DFT computational method, the B3LYP functional, and the 6-31G basis set. It is concluded that the system can be used to detect the presence of alkali metal atoms.
Government Support of Agriculture of Volgograd Region: Opportunities of Financial Infrastructure
Authors:   Volgograd State University, Shkarupa Ekaterina
Published: December 2023

The purpose of this article is to analyze the government support of agriculture in the Volgograd region, the basis of which is the financial and credit infrastructure. The changes in the Russian economy (pandemic of COVID-19, digitalization, high volatility in global markets, increased sanctions pressure) not only create barriers to the activities of agricultural producers but also open new opportunities for improvement. In the article, attention is paid to the study of economic research on the conceptual apparatus of government support for agriculture. The conclusion is drawn about its immature character because of the constant response of scientists to current events in the economy, which manifests itself in the emergence of new approaches to the definition and the permanent modification of existing ones. The variability of definitions of “government support of agriculture” presented in the study made it possible to concretize the goals that lead to the need for government support of agriculture and the set of ways to achieve them. It should be recognized that the industry has fairly low financial autonomy. The presence of financial resources (credit resources) is the basis of the activities of agricultural producers. The source of such resources is the financial and credit infrastructure of agriculture. Despite serious challenges, the industry has demonstrated stable results, and the main principle in the coming years should be the consolidation of this trend. Key directions for agricultural development in the region will continue to be the imperatives of government support and the new isolation of economic and political activity in the country. The financial and credit infrastructure of agriculture is expected to respond timely to such changes and adjustments as to the reliability and availability of financial and credit resources for businessmen in agriculture.

Published: December 2023

One of the priority directions for the development of the modern agrarian economy is the formation and development of human capital in agriculture and rural areas in the context of the strategy of social, economic, and spatial development of the Russian Federation. The purpose of the study is to analyze the current state, trends, problems, and ways of human capital development in the agro-industrial complex and rural areas of Russia. Methods of synthesis, analysis, systematization, logical and comparative analysis using information review, and statistical data processing were used as general scientific methods during the research. The paper reveals the essence and structure of human capital in the agro-industrial complex and rural areas, characterizes the indicators of its main components, analyzes their dynamics from 2017 to 2022, and identifies trends for further development. The analysis of the state of human capital in the agroindustrial complex and rural areas of Russia allowed us to identify both positive and negative trends in its development. Positive trends include an increase in wages in agriculture, some improvement in the structure of the rural population, active participation of farmers in educational programs, an increase in the share of the rural population with higher education, a decrease in the number of employed people who do not have basic general education, and the digitalization of the agro-industrial complex. Among the negative trends are the growth of the natural decline of the rural population, the aging of the population of rural areas, the lack of an attractive image of rural areas, and the low activity of agricultural managers in the creation and development of a personal brand. In conclusion, it is noted that, despite the presence of negative factors, there are real grounds and conditions for the development and improvement of quantitative and qualitative components of human capital in agriculture and rural areas.

Published: December 2023

Outsourcing plays an important role in the development of the Chinese automotive industry. The transfer of individual business processes to outsourcing allows you to expand the scale of production and ensure its modernization without a significant increase in costs. However, outsourcing not only improves production efficiency but also contributes to the sustainability of the automotive industry. The purpose of this article is to study the impact of outsourcing in various parts of the value chain of the automotive industry on the sustainability of its development. In addition to the traditional approach that defines three components of sustainable development (economic, social, and environmental), in this study we also analyze the technological one, which characterizes the possibilities of using innovative technologies to achieve sustainable development goals. SWOT analysis was used as a research tool. As a result of the study, the opportunities and risks of outsourcing in various parts of the value chain in the automotive industry were identified. The characteristics of environmental factors are given in terms of how they contribute to the development of outsourcing in the automotive industry. It is concluded that outsourcing in the automotive industry contributes not only to the development of the Chinese economy but also to those countries in which outsourcing work is carried out.
Bispectral Images of Radar Wideband Objects Characters Interpretation
Authors:   Mozhaisky space military academy, Neyolov V. V. , Samorodov A. A. ,   Mozhaisky space military academy, Shaldaev S. E. ,   Science research center
Published: December 2023

A methodological approach to the analysis of broadband radar signatures based on the application of the theory of bispectral estimation is presented. The approach involves analyzing the phase relationships of the target scattering centers, providing the more complete account of the information contained in the frequency characteristic of the target compared to the range portrait traditionally obtained using the Fourier transform. Analysis of phase connections allows identifying scattering centers formed as a result of multiple reflections of electromagnetic waves by structural elements of the object of complex shape or by separate close-located objects within the observed scene. The geometric image of the bispectra of the radar broadband object’s signature used for analysis is a hexagon in the coordinates “longitudinal range — longitudinal range,” which allows detecting mutual connections of scattering centers spaced along the direction of the location. The proposed methodological approach was tested using a synthesized frequency characteristic of an abstract multipoint target, as well as based on electrodynamic modeling data of complex backscattering fields. The comparison of the results of identification of scattering centers obtained using a bispectral image, the range portrait and the priori information about the location object indicates the correctness of the proposed methodological approach.

The article presents the results of a computational and experimental study of the acoustic intensification of methane oxidation processes in high-enthalpy oxygen-containing flow of hydrogen combustion products. The studies were conducted by using a duct with constant cross section and finite length. Initial specific enthalpy of the oxygen-containing flow is varied from 1600 kJ/kg to 2400 kJ/kg. The patterns of total enthalpy influence of the oxygen-containing flow of hydrogen combustion products and acoustic effect on the efficiency (completeness of chemical reactions) of methane oxidation were obtained. The dependence of acoustic frequency influence on the coefficient of completeness of physicochemical processes has been found. The values of fuel equivalence ratio were determined for various total enthalpies of the oxygen-containing flow, corresponding to diffusive and kinetic regimes of methane oxidation. The stability of methane oxidation process and the influence of forced acoustic oscillations on the spectral characteristics of static pressure pulsations in the flow were analyzed.

Significance Statement

Systemic inflammation in CKD can lead to anemia. Ziltivekimab, a fully human monoclonal antibody targeting the IL-6 ligand, has been shown to reduce systemic inflammation in patients with CKD. It has also been shown to increase serum albumin in patients on hemodialysis with inflammation and hyporesponsiveness to treatment with erythropoiesis-stimulating agents. This exploratory analysis of the RESCUE clinical trial found that among patients with CKD stage 3–5 and systemic inflammation, ziltivekimab treatment significantly increased hemoglobin (Hb) levels after 12 weeks compared with placebo. Ziltivekimab was also associated with significant increases in serum iron levels, total iron-binding capacity, and transferrin saturation. No major safety concerns were reported. Further clinical trials are warranted to study ziltivekimab's potential for anemia management in patients with CKD.

Background

In the phase 2 RESCUE clinical trial, ziltivekimab, a fully human monoclonal antibody against the IL-6 ligand, significantly reduced the biomarkers of inflammation compared with placebo, in patients with CKD and systemic inflammation (high-sensitivity C-reactive protein ≥2 mg/L). The aim of this subanalysis of RESCUE trial data was to assess the effect of ziltivekimab on Hb and iron homeostasis in this patient population.

Methods

This was an analysis of exploratory end points from the RESCUE trial (NCT03926117), which included 264 adults with CKD stage 3–5 and high-sensitivity C-reactive protein ≥2 mg/L. Participants received placebo or subcutaneous ziltivekimab (7.5, 15, or 30 mg) (1:1:1:1) once every 4 weeks, up to 24 weeks. End points for this analysis were changes in Hb and biomarkers of iron homeostasis from baseline to week 12.

Results

The trial was terminated early due to the coronavirus disease 2019 pandemic, and thus, data up to week 12 are presented. Hb levels significantly increased from baseline to week 12 with ziltivekimab 7.5, 15, and 30 mg (treatment differences versus placebo: +0.57 g/dl [95% confidence interval, 0.27 to 0.86], +1.05 g/dl [0.76 to 1.33], and +0.99 g/dl [0.70 to 1.28], respectively, all P < 0.001). Ziltivekimab was associated with significant increases in serum iron levels, total iron-binding capacity, and transferrin saturation from baseline to week 12 (P < 0.05 versus placebo for all doses and comparisons). Cases of sustained thrombocytopenia, sustained neutropenia, anemia, and iron deficiency anemia were infrequent and similar across all groups.

Conclusions

Anti-inflammatory therapy with ziltivekimab improved the markers of anemia and iron homeostasis in people with stage 3–5 CKD and systemic inflammation, suggesting a possible role in anemia management.
«SUSTAINABLE DEVELOPMENT» AS A STRATEGIC PROGRAM OF THE «NEW ELITES»

Published: December 2023

The article is devoted to the analysis of the concept of "new elites", proposed by K. Lash, his idea of "rebellion of the elites" in the context of the concept of sustainable development. The “revolt of the elites” is viewed through the prism of the problem: does the concept of sustainable development really serve as a tool for perpetuating social inequality and strengthening the autonomous existence of the super-rich and the super-poor? The addressee and addressees of the Agenda for Sustainable Development for the period until 2030 are identified. An interpretation is given to the first five goals of sustainable development. The conclusion is made about the manipulative application of the concept of sustainable development by the "new elites" in order to globally reformat social reality to fit their narrow group needs.

Digitalization is a global trend that makes it possible to introduce technological changes to achieve the goals of Russia's socio-economic development. At the same time, for their implementation, the need to use digital technologies in state and municipal government is of fundamental importance. At present, the main measures for the digitalization of state and municipal government are formulated within the framework of the national project "Digital Economy of the Russian Federation", which focuses on the implementation of municipal capital construction programs. The current state of the implementation of municipal programs to a small extent takes into account the possibilities of using digital technologies to improve the performance of government bodies. In this regard, it is advisable to identify the possibilities and limitations of the use of digital technologies in the implementation of municipal capital construction programs. The study analyzed the conceptual foundations for the digitalization of municipal capital construction programs, the main examples and action plans for the implementation of municipal programs established in the regulatory and legislative acts of Russia. We considered the strategic priorities and goals of these processes, as well as the features of information modeling technologies. The article presents both the benefits and challenges arising from the practical implementation of information modeling, as well as recommendations for further digital transformation.
Qualitative Analysis of the Optimization Model of Capitals Distribution

Published: December 2023

In the modern world, investments are the most important means that create conditions for the economic development of the country, introduce latest technologies (including digital ones that are popular today) and increase the quantitative and qualitative indicators of economic activity at the micro and macro levels. Inclusion of investors with small savings in the investment process is a paramount task, because they can provide the country's economy with significant investment resources.
Household savings determine supply in the financial market, which, in turn, is linked to consumer spending. Due to the constant interest in investment and consumption - two basic components of total expenditure in the economy - it seems possible to approach the issue of their best distribution through economic and mathematical modeling.
The article considered the model of optimal distribution of capital and consumption in the presence of a budget limits and provides its qualitative analysis using the apparatus of the theory of optimal control.

Corporate social responsibility is the responsibility of a business for the consequences of its activities, its obligation to effectively fulfill its function, to add value and voluntarily implement social policies, ethical standards and decision-making that will benefit all stakeholders. Thanks to government support and the initiative of business, Russia is actively implementing social programs whose stakeholders are the state, business and society. The subject of the study are tools that determine the social utility of corporate social responsibility for society and the social benefit for the state and business. The purpose of the study was to substantiate a methodological approach to assess corporate social responsibility based on the function of social utility of stakeholders. The hypothesis of the study was the assumption that the developed methodological approach to the assessment of corporate social responsibility will make it possible to determine for stakeholders, namely, the state, business and society, social benefits in the development and implementation of corporate social responsibility. An analysis of existing methods for assessing corporate social responsibility confirmed that they assess it only from the standpoint of the full responsibility of business, with the state and society as recipients of social benefits. An analysis of the conditions, factors and events showed that corporate social responsibility reflects the sustainable development of not only business, but also the state and society as a whole. Despite the positive trends, there are problems that require immediate solutions — it is equal contribution into corporate social responsibility by all stakeholders, definition of criteria of their responsibility and social activity.
