The electromagnetic processes in elementary dc converter according to the Luo topology with inverting output in modes of continuous and discontinuous conduction were studied. Using the method of averaging in the state space based on Lagrange theorems, mathematical models of converter for mentioned modes of operation have been devel-oped. The use of developed models made it possible to obtain analytical expressions for calculating the average and pulsation values of currents and voltages in the reactive elements of the converter, as well as their ripple coefficients. Graphical dependences of the mentioned parameters were calculated in the entire commutation range of converter, taking into account the conduction modes. It is shown that, in comparison with traditional topology of buck-boost con-verter, the output filter in elementary Luo converter with inverting output significantly reduces the ripple coefficient of output voltage. It was determined that the amount of voltage ripple reduction is proportional to the product of the in-ductance and filter capacity values, as well as the square of the switching frequency and does not depend on the con-ductivity mode of the converter.

In this paper, we present the results of studying the features of plasmon- enhanced photostimulated diffusion of silver into thin films of chalcogenide glasses (ChG), in particular, As 2 S 3 and GeSe 2 . To ensure excitation of surface plasmon-polaritons (SPPs) at the interface between silver and ChG films, silver diffraction gratings with periods of 899 and 694 nm were used as substrates. The samples were exposed to the p-polarized radiation of a He-Ne laser (λ = 632.8 nm). The radiation of the same laser, attenuated by two orders of magnitude, was used to detect SPP, which enabled to study the kinetics of photostimulated processes in the thin-layer structure of Ag–ChG. It has been established that in the initial period of exposure, the SPP electromagnetic field significantly enhances the photostimulated flux of silver ions in ChG (by 2-3 times). The photodissolution kinetics of Ag in ChG is defined by the features of the granular structure of the investigated thin chalcogenide films. For the GeSe 2 film with the effective thickness 8 nm, the kinetics of the film refractive index increase caused by silver photodoping is well approximated by a logarithmic dependence. For the Ag–As 2 S 3 structure (the effective thickness of the As 2 S 3 film is 14.8 nm), this kinetics is closer to the linear one; moreover, for photodoping without SPP excitation, the kinetics is somewhat superlinear, while with plasmon excitation, it is sublinear. The main physical mechanism responsible for the acceleration of the process of photostimulated diffusion in the structure under study appears to be an accelerated generation of electron-hole pairs, which takes place in the ChG layer near the interface with the metal, where the SPP electromagnetic field strength is maximum, and/or plasmon- assisted hot carrier generation due to plasmon scattering on the surface of the metal film and subsequent internal photoemission of electrons from silver into chalcogenide.

Optical properties of 1D nanocrystals of cadmium sulfide synthesized by vapor– liquid–solid growing were investigated as the function from such technological parameter as overpressure of sulfur vapor at the synthesis process or post-processing by the additional annealing in the sulfur atmosphere (sulfurization). The analyses of UV-vis absorption and photoluminescence spectra indicate considerable dependences of CdS nanocrystals optical parameters from sulfur compensation degree at the synthesis process. The photo- luminescence spectra are characterized by changing the ratio of intensities of the defect level and near band edge emissions at overpressure sulfur vapor treatment. A significant decrease in the intensity of defect level emission after the growth or post-growth treatment in sulfur vapor has been observed. Optical absorption edge calculated using the Tauc relation demonstrates improvement of the crystal structure, which is reflected by the rising optical band gap value that approaches to the value for the bulk material at curing of sulfur vacancies by different technological ways. Optical properties obtained by absorption and luminescent measurements demonstrate total correlation, which corresponds to applied technology.

In this paper, nucleation parameters such as induction period, interfacial tension, metastable zone width, radius of critical nucleus and Gibbs free energy change in solution- grown triglycine sodium molybdate (TGSM) single crystals are studied. The solubility of TGSM at different temperatures has been determined. The induction period and metastable zone width have been experimentally found for optimizing the growth process. Various critical nucleation parameters have been calculated from the experimentally obtained values based on the classical nucleation theory. The nucleation rate is found to increase with the growth of the supersaturation value. The third order non-linear parameters such as absorption coefficient (β), susceptibility (χ (3) ) and refractive index (n 2 ) obtained from the Z-scan analysis confirm the self focusing and reverse saturation absorption nature of the grown crystals.

Porous materials occupy an important place among the materials of electronic equipment. Nanopores, which are obtained by ion irradiation of materials, have a complex internal structure that depends on the interaction of fast ions with the substance. Obtaining such structures is important, in particular, in the manufacture of biosensor devices based on them. The most effective methods of studying their properties are computer simulations. However, effective computer models of track structures, necessary for the development and improvement of modern biosensors, are not being created actively enough. The approach proposed here involves a detailed study of the interaction of ion flows with the inner surface of the nanotrack. This approach takes into account the structural features of the inner surface of the track as well as the role of adsorption and scattering centers and other local centers. In the existing approaches, the processes mentioned above are mainly described phenomenologically, which does not indicate the ways of modifying the characteristics of the material that is necessary for the device improvement.
Experimental Restoration and Reconstruction in Music Archaeology
Authors: Fang Jianjun
Published: December 2023

Restoration attempts to recover the original shape of excavated musical artifacts that have been damaged. Reconstruction is primarily focused on unearthed musical instruments or those depicted in images, and aims either at creating reproductions of playable replicas and imitations, or at simulative manufacturing and model reconstruction. Restoration, on the other hand, can be carried out in tangible or intangible ways. Tangible restoration can be perceived visually, while intangible restoration is instead sonic, and therefore aurally perceptible. Restoration not only recovers the integrity of fragmentary instruments, but also, if possible, reconstructs the sound of the original instrument based on pitch measurement and analysis. Restoration can also be applied to musical iconographic sources and musical textual symbols, such as musical notations and sur-viving classical texts. The restoration of musical notation is not the same as transcription of musical score. The restoration of epigraphic texts aims mainly to restore blurry and otherwise unclear or missing characters. Reconstruction, on the other hand, is a kind of simulation experiment that uses physical or virtual manufacturing to copy, imitate, and reproduce musical remains, for the purpose of exploring ancient musical practices. Based on excavated objects, musical instruments can be copied or imitated, while simulative experiments based on iconography are necessarily limited to speculation.
Woodwind Instruments in al-Fārābī’s Kitāb al-Mūsīqī al-Kabīr
Authors: Gökpınar Yasemin
Published: December 2023

Al‑Fārābī (d. 950 CE), the so-called ‘Second Master’ (Aristotle being the First Master), is known for his influential works on philosophy, especially his commentaries on Aristotle, as well as for his works on logic, physics and metaphysics, ethics, and politics. It was on behalf of al‑Karḫī, Caliph ar‑Rāḍī’s (r. 934–940 CE) wazīr, that al‑Fārābī wrote his Grand Book on Music, explaining musical concepts such as rhythm and melody to the wazīr. As a logician and practicing musician, he combined and improved upon different sources, such as Greek musical theory, as well as on the Arabic authors and musicians al‑Kindī (d. after 870 CE) and Isḥāq al‑Mawṣilī (d. 850 CE).
In this paper, I discuss several issues related to woodwind instruments mentioned in al‑Fārābī’s Grand Book on Music. Al‑Fārābī expounds on their interconnections with the tonal production of other instruments, specifying their tone system in terms of finger positions on the fretboard of the ʿūd.
Further questions address the relation between theory and practice, as well as some considerations about the modes that seem to be common on woodwinds.

According to the Rome IV consensus (2016), functional gastrointestinal disorders (FGIDs) are disorders of the interaction between the gut and the brain. A crucial role in the realization of this mechanism is played by the key neurotransmitter serotonin. Aim - to investigate the influence of serotonin on the formation of clinical symptoms in children with FGIDs. Materials and methods. Under observation were 72 children aged 10-18 years with FGIDs. The Group I consisted of 30 children with combined functional dyspepsia (FD) and irritable bowel syndrome (IBS), the Group II included 42 children with FD. A control group of 20 healthy children was established. The diagnosis of FD and IBS was established based on the analysis of clinical symptoms according to the Rome IV criteria (2016). The severity of clinical symptoms was assessed using the Likert scale from 0 to 5 points. The study of serotonin content in whole blood was conducted using a fluorometric method after adsorption on carboxymethylcellulose. Results. The intensity of abdominal pain and the severity of dyspeptic syndrome in children with combined FD and IBS is higher than in children with FD (p<0.01; p<0.05, respectively). The serotonin content in whole blood in children with FGIDs is lower than in healthy children (p<0.001). In children with combined FD and IBS, the serotonin content is lower than in children with FD (p<0.05). Reverse correlation links were found between serotonin content and the intensity of pain syndrome (r=-0.7), the severity of dyspeptic syndromes (r=-0.5), constipation (r=-0.7), and diarrhea (r=0.7). Conclusions. The obtained research results indicate the influence of serotonin on the formation of clinical symptoms in children with FD and combined FD and IBS. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Assessment of the state of exercise tolerance (ET) after the transfer of COVID-19 is necessary to determine the long-term consequences of the coronavirus disease. Purpose - to assess the state of ET and analyze changes in myocardial reserve indicators in children who have experienced COVID-19 of varying degrees of severity. Materials and methods. 155 school-age children took part in the study. 120 children with a confirmed diagnosis of COVID-19 in the anamnesis and a period after COVID-19 of more than 12 weeks (main group) and 35 healthy children who did not suffer from COVID-19 (control group). The Group I (n=49) included children who contracted mild COVID-19; the Group II (n=40) - children who suffered from COVID-19 of moderate severity, the Group III (n=31) - children who contracted COVID-19 with a severe course. General clinical, instrumental (cycle ergometry), and statistical research methods were used. Results. In the main group, the average value of maximum oxygen consumption (VO2max) was 26.86±6.69 ml/kg/min, and in the control group - 38.29±5.54 ml/kg/min (p<0.001). The analysis of this indicator in the Groups I, II, and III showed that transferred COVID-19 affects the level of ET in boys regardless of the severity of COVID-19 (p<0.01). In girls, reduced ET was determined in the case of moderate and severe course of COVID-19. The analysis of myocardial reserves indicators showed that among children who fell ill with COVID-19, the worst indicators were observed in the Groups II and III (p<0.01). Conclusions. Transmitted COVID-19 affects the state of ET and indicators of myocardial reserves in children in the period more than 12 weeks after COVID-19. The level of changes in the state of ET, values of the cardiac and vascular component of physical load support, and myocardial reserves depend on the degree of severity of the transferred COVID-19, which is confirmed by correlations of varying strength between these indicators and the degree of severity of COVID-19. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.
The Transformation of Consumers’ Remedy in the Context of Sanctions Pressure on the Russian Federation
Authors:   Volgograd Institute of Management, branch of the Russian Presidential Academy of National Economy and Public Administration, Belova Olesya
Published: December 2023

Introduction. The civil legislation sphere is the fundamental basis of private law relations. At the same time, civil legislation is most affected by various circumstances impacting both substantive and procedural law. Recently, the impact of sanctions pressure on the Russian Federation has been an urgent topic, which is naturally reflected in the development of civil law relations. The impact of the sanctions of foreign states is particularly pronounced in the field of consumer protection, since foreign companies are abandoning the Russian market and consumer problems remain unresolved. Consumer protection in the context of sanctions pressure on the Russian Federation is an important task for the legal science, both from the material and procedural sides, and is associated with the need to develop appropriate solutions. Since the science of civil law is faced with the task of developing various ways of solving problems in the field of consumer protection under sanctions pressure, this is the purpose of the study. Methods. The methodological framework for the research is a set of methods of scientific cognition, among which the main ones are analysis, synthesis, generalization, and comparative jurisprudence. Results. Within the framework of the study, the author has analyzed the role of existing legal norms on consumers’ remedies from the point of view of their enforcement in the conditions of sanctions pressure on the Russian Federation. Based on the analysis, it is concluded that, on the one hand, the existing legislation on consumers’ remedies fulfills its main function but does not correspond to modern economic conditions of development as a result of the abandonment of foreign companies. The application of the norms of substantive law cannot be fair and expedient in situations where the consumer remains in an economically disadvantageous financial situation. The author of the study has proposed a solution by improving the norms of substantive law in the field of consumer protection, whose change will direct law enforcement to the path of a fair resolution of cases. From the author’s point of view, a legislative proposal to amend the Law on Consumer Protection seems optimal, which will allow solving this problem not only with substantive but also procedural law. The legislative initiative applies to cases where it is impossible to implement the plaintiff’s claim due to force majeure and consists of empowering the court to independently replace the claim with a similar one so that the interests of the consumer are not violated.

Published: December 2023

Introduction. The scientific paper discusses some issues related to the functions performed by the investigator in criminal proceedings. The authors identified and justified the significance of the research topic under discussion and made suggestions for considering documenting as an investigator’s function. The chosen problem identified the purpose of the study as highlighting the documenting of the investigator’s decisions as a separate function. Methods. With the help of the dialectical method of research, generalization, comparison, analysis, and synthesis, as well as others, it became possible to form the paper in the context of considering questions about the functions of the investigator. Results. The main results of the study are recommendations on drawing attention to the problems of documenting and supporting procedural actions and decisions in criminal proceedings. The paper discusses the issues of functions in criminal proceedings, their meaning, functions of parties, and their division among them. Currently, there is no consensus on the scope of the investigator’s functions in criminal proceedings, which is due to his ambiguous dual role as prosecutor or researcher in criminal proceedings. Conclusions. As a result of the conducted research, the authors have come to the conclusion that it is necessary to develop and implement at the substatutory level some recommendations and instructions on the rules of record-keeping at the preliminary investigation. The importance of professional training for future specialists, including in drafting criminal procedural acts and documents, is noted. The necessity of further investigation of questions about the functions of the investigator is established.

Published: December 2023

The article describes the experience of designing and conducting a competition of municipal strategies “Implemented Strategies: From Idea to Execution”, held in 2022. The competition is seen as a method of practice analysis of municipal strategic planning in Russia during 25 years (1997–2022). The materials of participants i.e. 33 municipalities from 19 regions were studied. The participants were divided into three size groups by population. In each group, the winner in the final nomination “The Best Strategic Planning System” was determined based on the results in two intermediate nominations – “The Most Stable Strategic Planning System” and “The Best Flagship Project.” The best in the final nomination were the city of Belogorsk (Amur region), Surgut district and Surgut (both are located in Khanty-Mansi Autonomous Okrug – Yugra). The systems of strategic planning of Koltsovo work settlement (Novosibirsk region), Surgut district and the city of Surgut, starting their history since 2002, 2005 and 2004, respectively, are recognized as the most stable ones. In terms of flagship projects, Zadonsky district (Lipetsk region), Michurinsk (Tambov Region) and Novorossiysk (Krasnodar Krai) are in the lead. Based on the materials of the competition, two approaches to strategies’ updating are identified: frequent change of strategies with a short planning horizon and regular updating of a long-term strategy. The flagship projects were grouped by industry orientation. (Most of the projects are presented in the groups “Production”, “Infrastructure, urban environment, transportation”, “Social sphere, culture, sports”; few projects were in the areas of housing and communal services and ecology.) The criteria for the quality of a set of flagship projects are identified: balance of the set of projects by industry, clear relation with the priorities of the strategy, provision of accelerated development in a certain area, concreteness of the results.

The expansion of the borders of the Russian Federation in 2022 by means of joining four new subjects, i.e. Donetsk Republic, Zaporozhye region, Luhansk Republic and Kherson region is one of the most important stages in the history of the country. The new subjects have significant human, industrial and agricultural potential, which will strengthen the economic position of the country in the world in the future. The newly joined areas are located in favorable climatic conditions of the Northern Black Sea coast, therefore, first of all, they have recreational and agricultural advantages. Since Russia as a whole has completed the process of foodstuff import substitution and is gaining an increasing weight in international food trade, the expansion of the agricultural and food production base in the short term should generally affect agro-industrial complex production and the export potential of the country positively. Of course, the advantages of the new regions will require significant investment and efforts to restore the economy and ensure security. Nevertheless, there is every reason to believe the expansion of the state territory has not only political but also positive economic consequences in the form of growth, above all, of the agro-industrial complex. In this regard, assessment of agricultural potential and opportunities for processing in new regions of the country is an urgent task. The purpose of this paper is to assess the dynamics of the agro-industrial sector of the new Russian regions on the basis of statistical data on their economic development in recent years. It is estimated as the volume of agriculture over the past decade, its structure and the value of output in horticulture and the livestock industry. To accomplish the task, such methods of general scientific knowledge as analysis, synthesis, as well as the tabular method of information processing were used. In the course of the study, information on the development of agriculture in four new regions, both in absolute terms and relative to the total output of both Ukrainian and Russian agricultural production, was obtained.

In the new system of macroeconomic coordinates, the temporal presentation of the process of forecasting technological development of industry is fundamentally changing within the concept of structural reform of the national economy. Because of the high turbulence of factors, especially the external environment, despite the absolute importance of scientific perspective, it is possible to speak with a greater probability of their occurrence only in a short- and mediumterm context. In accordance with this, the guiding role of technological foresight in the management of breakthrough technologies is strengthened precisely within these time horizons. And the success of achieving the goals is determined by the digitalization of a decision-making process and the introduction of closed-loop economic models within the framework of the interaction of enterprises in the breakthrough technology sector. This new stage of development of industrial enterprises (in terms of activity, specialization, and development of circular value chains) reflects their orientation to the parameters of technological foresight. The paper presents the results of a critical analysis of modern approaches to research and technological foresight impact assessment methods on the regions’ industrial structural reform, gives its program modules embedding hierarchical representation in conjunction with the goals of macro, meso and micro levels. The technological foresight global goal-oriented role at the macro level, its adaptive (to the region’s specifics) role at the meso level and the technological forethought role at the level of a specific industrial enterprise (association) realizing regional and sectoral goals is substantiated. On the basis of the empirical analysis of comparative dynamics of indicators of innovation activity in the regions of Russia, reference marks were identified. On their base clusters were built that characterize the dynamics of the development of federal entities of the Russian Federation in terms of the technological type of their industry. As a result of repeated clustering, the clusters or industrial drivers for the implementation of technological foresight targets, including the ones in the regions of South of Russia were identified. This allowed us to draw reasonable conclusions about the appearance of technologically breakthrough innovation clusters in these regions and the dynamics of their development.
MULTI-STRATIFIED EFFECTS ON STAGNATION POINT NANOFLUID FLOW WITH GYROTACTIC MICROORGANISMS OVER POROUS MEDIUM
Authors: Rajeswari Ponniah Meena , De Poulomi
Published: December 2023

The present investigation focuses on the intricate interplay of multiple stratified effects on the stagnation point
nanofluid flow with gyrotactic microorganisms across a porous medium. The study encompasses a comprehensive
numerical analysis, examining the impacts of varying parameters, such as stratification parameters, porosity, etc., on the flow characteristics. The gyrotactic behavior of microorganisms further adds complexity to the analysis. The findings contribute to a deeper understanding of the combined effects and their consequences on heat and mass transfer within the system. Such insights hold relevance in various engineering and environmental applications, including biofuel production and water treatment processes. Numerical solutions are obtained via the fifth order Runge-Kutta-Fehlberg method with shooting technique. A graphical view of the velocity, temperature, concentration, and density of the microorganism-profile-concerned parameters are discussed in detail. A comparison with the local Nusselt number for distinct values of the Prandtl number reveal the validity of current results. The temperature, concentration, and density of microorganism fields lessened with enhancement of thermal, solutal, and motile stratification parameters. Also, concentration field boosts with enhancement of thermophoresis and Brownian motion parameter.
“Outlier” latenti nelle costruzioni a lista: Il caso del discorso politico su Twitter
Authors: Barotto Alessandra , Combei Claudia Roberta
Published: December 2023

This contribution investigates the use of list constructions as a rhetorical tool in the Twitter communication of four Italian political leaders (Giorgia Meloni – Fratelli d’Italia; Matteo Salvini – Lega; Matteo Renzi – Italia Viva; and Nicola Zingaretti – Partito Democratico), by analyzing a corpus of 4,371 tweets from which 449 lists have been extrapolated. The results suggest that there is indeed a deliberate and strategic use of this construction and that the main purpose of list outliers is to persuade readers (potential voters).

CLAIMS FOR DISQUALIFICATION FROM VOTING AS PER THE LAW ON PROCEDURES FOR FOREIGN INVESTMENTS IN THE BUSINESS ENTITIES OF STRATEGIC IMPORTANCE
Authors:   Perm State University, Fedyaev D. A.
Published: December 2023

Abstract: the author focuses on studying the claims for disqualifying the foreign investors from voting at the meeting of shareholders (participants) of a business entity of strategic importance. This category of claims, which is not so common in Russian legal practice, is increasingly used in connection with exercising control over foreign investments by the Federal Antimonopoly Service of Russia in strategic sectors of the economy. Based on the analysis of the current legislation and existing doctrinal approaches, the conclusion is made about the priority of the judicial procedure for disqualifying the foreign investors from voting at the meeting. The ways are proposed to eliminate the offense after the court has taken the decision on disqualifying from voting.

Abstract: the article reveals the conditions for applying the matrix games toolkit to situations with legal content. Using the example of case no. A40-162373/2020 on the recovery of compensation for infringement of exclusive copyright, the compilation of the “profitability” matrix is demonstrated. Using the Bayes, Wald, Savage and Hurwitz criteria the optimal strategy of legal behavior of the copyright holder and the violator is mathematically justified. It is shown that predicting the outcome of a civil dispute using these criteria will allow the participants of the turnover to determine the strategy of legal behavior in the absence of a unified approach in law enforcement practice and minimize their own costs.

Authors:   Perm State University, Fedoseev A. A.
Published: December 2023

Abstract: the principle of cooperation of civil law subjects, traditionally referred to as the principles of the law of obligations, has a much deeper content, allowing it to extend its effect to other types of civil law relations. Corporate legal relations, based on a material relations consisting in the unification of efforts by civil law subjects to achieve a common goal – the effective functioning of the corporation – cannot exist in isolation from the idea of cooperation and mutual assistance of its participants. In the article, the author analyzes the content of the principle of cooperation of civil law subjects through the prism of the specifics of the content of corporate legal relations and the problems of its subject composition. As a result, the author comes to the conclusion that in a corporate legal relations, the principle of cooperation is implemented through the doctrine of fiduciary duties both in terms of the imperatives of the information cooperation group aimed at ensuring the awareness of members of the management bodies of the corporation and the activity cooperation group aimed at eliminating accidental obstacles to achieving the goal of the legal relations.

Abstract: the article examines the problems of legal regulation and practical con‐ duct of interrogation, confrontation and identification using video confe‐ rencing to optimize evidentiary activities at the stage of preliminary in‐ vestigation. A comparative analysis of remote actions in pre‐trial and judicial domestic criminal proceedings is carried out. The necessity of ex‐ panding the use of the capabilities of modern information and telecom‐ munication technologies at the stages of initiation of a criminal case and preliminary investigation is substantiated. The detailed procedure for remote interrogation, confrontation and presentation for identification in pre‐trial proceedings is presented. The corresponding formulations of amendments to the current Code of Criminal Procedure of the Russian Federation are proposed, which allowed to justify the updating of the updating of the criminal procedure form in relation to the procedure for the formation of evidence. It is concluded that conducting remote inves‐ tigative and other procedural actions contributes to procedural economy, compliance with reasonable deadlines in the investigation of criminal cases and contributes to improving the level of information competence of relevant authorities and officials.
