Published: October 2023

Aims. We developed a cluster-detection method based on the code DBSCAN to identify star clusters in the central region of the Small Magellanic Cloud (SMC).

Methods. Two approaches were used to determine the values of the free parameters of DBSCAN. They agree well with each other and can be used in the fields that are studied without any a priori knowledge of clustering, characteristic scales, or background density. We validated the success of the DBSCAN cluster-detection method on recent cluster catalogues after introducing a cluster-classification scheme based on three diagnostics that relie on colour-magnitude diagrams and growth curves. We used data from the Magellan Telescope at the Las Campanas Observatory in Chile and from Gaia Data Release 3.

Results. As a byproduct of the validation process, we revisited objects that were classified as clusters in recent compilations. We found that 40% fail all diagnostics and most probably are not clusters. DBSCAN was very successful in recovering actual clusters with high precision and recall.

We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49, and the alert that this was a TESS planet candidate with a period of 21.3 days went out in April 2020. However, ground-based follow-up observations, including seeing-limited photometry in and outside transit together with precise radial velocity (RV) measurements with CARMENES and HIRES revealed that the true period of the planet is 10.6 days. These observations also allowed us to retrieve a mass of 5.74 ± 1.46M⊕, which together with a radius of 2.08 ± 0.12R⊕, means that TOI-1801 b is most probably composed of water and rock, with an upper limit of 2% by mass of H2in its atmosphere. The stellar rotation period of 16 days is readily detectable in our RV time series and in the ground-based photometry. We derived a likely age of 600–800 Myr for the parent star TOI-1801, which means that TOI-1801 b is the least massive young mini-Neptune with precise mass and radius determinations. Our results suggest that if TOI-1801 b had a larger atmosphere in the past, it must have been removed by some evolutionary mechanism on timescales shorter than 1 Gyr.

Aims. In this work, we analysed new LOw Frequency ARray observations of the mini halo in the cluster RBS 797, together with archival Very Large Array observations and the recent Chandra results. This cluster is known to host a powerful active galactic nucleus (AGN) at its centre, with two pairs of jets propagating in orthogonal directions. Recent X-ray observations have detected three pairs of shock fronts within 125 kpc from the cluster centre, connected with the activity of the central AGN. Our aim is to investigate the connection between the mini halo emission and the activity of the central source.

Methods. We have used different methods to separate the emission of the central source from the diffuse mini halo emission, and we have derived the radial spectral index trend of the mini halo.

Results. We find that the diffuse radio emission is elongated in different directions at 144 MHz (east-west) with respect to 1.4 GHz (north-south), tracing the orientation of the two pairs of jets. The mini halo emission is characterised by an average spectral index α = −1.02 ± 0.05. The spectral index profile of the mini halo shows a gradual flattening from the centre to the periphery. Such a trend is unique among the mini halos studied to date, and resembles the spectral index trend typical of particles re-accelerated by shocks. However, the estimated contribution to the radio brightness profile coming from shock re-acceleration is found to be insufficient to account for the radial brightness profile of the mini halo.

Conclusions. We propose three scenarios that could explain the observed trend: (i) the AGN-driven shocks are propagating onto an already existing mini halo, re-energising the electrons and leaving clear imprints in the mini halo spectral properties. We estimate that the polarisation induced by the shocks could be detected at 6 GHz and above; (ii) we could be witnessing turbulent re-acceleration in a high magnetic field cluster; and (iii) the mini halo could have a hadronic origin, in which the particles are injected by the central AGN and the diffusion coefficient depends of the cosmic ray proton momentum. Future observations in polarisation would be fundamental to understand the role of shocks and of the magnetic field.
Determining the directionality of anthropogenic noise using an underwater acoustic vector sensor: a case study in a Norwegian fjord
Authors: Zhang Guosong , Cresci Alessandro , Browman Howard I.
Published: October 2023

Sources of anthropogenic noise in the ocean have temporal and directional characteristics. Characterizing the soundscape requires identifying the directionality of the sources of noise in addition to the non-directional sound pressure. An underwater acoustic vector sensor (AVS) can be used to provide the directionality of incoming noise, and the concomitant sound pressure. We present an analysis of measurements from an AVS deployed in a Norwegian fjord in which there is frequent commercial ship traffic. We assessed the directionality of various known and unknown noise sources and used it to interpret the associated sound pressure. The fjord soundscape consists of time-varying noise directionality and intensity from anthropogenic sources, especially shipping activity. This case study highlights the benefits of using information from an AVS to assess noise directionality in a soundscape.

Published: October 2023

The objective of the study was to investigate the influence of SNP CAST 283 on the development of meat qualities in young cattle of Hereford and Limousin breeds in postnatal ontogenesis. The objectives of the study included: genotyping of young cattle by SNP CAST C283T, determination of genotypic structure, allelic state, level of genetic diversity and equilibrium of the studied herds of Hereford and Limousin cattle, study of live weight dynamics in postnatal ontogenesis, post-slaughter carcass evaluation, chemical composition of beef and structural and mechanical properties of meat obtained from steers of different genotypes. The results of genotyping of bulls of Hereford and Limousin breeds by SNP CAST C283T, testify to high frequency of occurrence in both herds of genotype CASTSS and low desirable genotype CASTTT (7.5% in Herefords and 4.18% in Limousins), a low frequency of the allele CASTT (0.29 and 0.26) was noted. In our studies, no significant relationship of the studied SNP CAST C283T with weight growth, post-slaughter parameters and chemical composition of meat of steers of different genotypes was found. There was a significant association of the studied polymorphism with lower cutting force of the longest muscle of the back in steers with the genotype CASTTT at the end of the first day and on the third day of the experiment, which allows us to recommend this polymorphism as a marker of "tenderness" of beef in selection work with Hereford and Limousin cattle.

Published: October 2023

The volume of forest resources is the most important characteristic in tracking the supply chains of raw materials, along with species and quality. To date, there is no unified automated methodology designed to track the movement of forest resources. The paper considers the use of an unmanned aerial vehicle for the purposes of accounting and accurate calculation of timber volumes both in the standing and in the form of stacks of round timber. The users of the presented methodology are timber industry enterprises, as well as authorities and departments for the purpose of state control. The developed methodology will make it possible to obtain prompt and accurate information on the volume of timber along the entire path of their extraction and processing. This, in turn, will reduce the cost of the procedure for assessing the volume of timber, make the procedure for monitoring their movement more independent and transparent.

Published: October 2023

Mechanical trauma of the eye is an example of a limited injury in which systemic changes in the immune system occur. The aim of the study was to investigate the dynamics of morphological manifestations of traumatic inflammation in experimental mechanical trauma of the eye with the inclusion of quercetin in the schemes of experimental therapy. The experiment was conducted on male mongrel rats of six-month age, weighing 220-240 g in the number of 120 animals. All animals were given a penetrating wound of both eyes. Group 1 animals were not treated for mechanical ocular trauma. Group 2 rats received standard therapy for eye injury, group 3 animals received standard therapy with the addition of quercetin injections intraperitoneally, and group 4 animals received quercetin injections only. To obtain macro preparations of the eyeball, adjacent tissues and subsequent preparation of histologic preparations of both eyes, the head of each animal was fixed in a solution of 10% neutral formalin. Histologic sections were examined using the ocular stereometric grid of G.G. Avtandilov. Conclusions: addition of quercetin injections to the standard therapy of eye trauma promotes intensification of reparative processes, reduction of purulent inflammation intensity and phagocytosis in the remote period, increase in the number of immunocompetent cells in the peri-circumferential zones.

Published: October 2023

Antioxidative and cryoprotective effects of a novel synthetic antioxidant–1,1'-(piperazine-1,4-diyl)bis(2-(2-hydroxyphenylthio)ethanone (AO) is presented in comparison with commonly known antioxidant butylated hydroxytoluene (BHT). Superoxide anion radical scavenging activity of new AO and the increase in superoxide dismutation activity of the Russian sturgeon’s (Acipenser gueldenstaedtii) sperm were established in the presence of this compound. It was shown that the new phenol agent reduces level of carbonyl oxidation by-products, which can react with thiobarbituric acid (TBARS), in Russian sturgeon’s native and frozen/thawed sperm, which indicates the manifestation of antioxidant properties by this compound including under the action of damaging factors during cryopreservation. A beneficial effect of this phenol derivative on the activity indicators (the percentage of motile sperm cells and total period of sperm movement) of the Russian sturgeon’s frozen/thawed sperm was shown, which indicates the cryoprotective effect of a novel synthetic antioxidant. The efficiency of the AO exceeds the effect of BHT under cryopreservation conditions of Russian sturgeon sperm in the presence of the modified Stein’s medium, but further studies are needed on the effect of a new phenol agent on the fertilizing capacity of Russian sturgeon’s sperm.

Rice seeds at each stage of ripening are characterized by a certain state, structure and moisture. Such properties of rice as germination, nature, quality and duration of storage depend on moisture content. Biochemical processes in the grain do not end at the filling stage, but continue for some post-harvest period. To safely preserve the rice gene pool, it is necessary to clarify the effect of seed maturity and storage time on seed quality. The varietal characteristics of rice seeds were studied using 8 Kuban varieties harvested on days 35 and 45 after flowering. The structural-phase state of freshly harvested grain and after 5, 10 days of ripening in natural conditions at room temperatures, and then the dynamics of sowing qualities after 1, 6 and 10 months of storage are discussed. The following parameters were studied: moisture, germination, length of the seedling and seed root, mass of 1000 grains. Differences in the moisture yield of grain of different degrees of maturity, varieties with different types of grain are shown. The results of the evaluation of rice physico-chemical indicators at the end of post-harvest ripening are presented. Varieties with slow moisture yield during ripening were distinguished by increased grain size: Yakhont, Rubin, Thaibonne and Zlata. The germination of seeds increased as they ripened, compared with freshly harvested ones, after a month it increased by almost 50%, and reached its maximum value by 6 months of storage, after 10 months, on average, germination for the group of varieties has already decreased by 6%. The stage of seed harvesting significantly influenced the germination rates.

Modeling of the group structure of waves in the problems of the impact of waves on a ship
Authors: Zapevalov Alexander
Published: October 2023

The variability of the group structure sea surface waves is analyzed by numerical simulation. The analysis is carried out on the basis of an analytical model that describes the group structure of nonlinear waves. The characteristics of the wave group are controlled by two parameters, the group height factor (GFH) and the group length factor (GLF). With a fixed wave energy, the maximum wave height is determined only by GFH and does not depend on the GLF. It is shown that if GFH varies from 0.1 to 0.9, then at a fixed wave energy, the maximum wave height in the group increases by one and a half times. As the GLF increases, the number of high-height waves successively affecting the ship increases.

The article considers the issues associated with the elastic and plastic properties of fluoroplastic in the state of delivery and radiation hardened. The statement about the radiation hardening of fluoroplastic improves thermal deformation characteristics is substantiated. The results of kinetic microindentation are studied in comparison with the initial state in the temperature range of 80 - 400 0C. The effect of temperature on the ratio of the work of the elasticity and plasticity forces is analyzed. Particular attention is paid to the elastic properties of fluoroplastic. The assumption is substantiated that it is possible to improve the elastic properties of fluoroplastic by radiation treatment at elevated temperatures, which are typical for high-speed axial piston pumps. On the basis of the study, it was found that the use of radiation hardening treatment of fluoroplastic is promising for increasing the durability of movable seal rings.

Authors: Chudina Olga , Simonov Dmitry , Simonova Tatyana , Litovchenko Alexander
Published: October 2023

The effectiveness of hardening of the surface layer of machine parts is evaluated by the operational properties of the surface layer and depends on many conditions that characterize the specific features of the technological process in which this method of hardening is carried out. The surface plastic deformation of structural steels with the use of ultrasound is studied. Four variants of hardening are considered: ultrasonic treatment with continuous supply of ultrasonic energy, pulse ultrasonic treatment, combination of ultrasonic treatment with subsequent pulse treatment, ultrasonic treatment after hardening with induction heating. It is shown that ultrasonic treatment increases microhardness of surface layer of structural steels by 1.5 times, HF hardening by more than 2 times, HF hardening + UZO combination by 3 times and HF hardening + IUZO combination by 3.2 times. Ultrasonic treatment increases compression stresses occurring in steel surface hardened by HFI hardening. The compressive stresses increase especially strongly after pulse ultrasonic treatment with five passes and reach the value of 1200 Pa.

Legal foundations of a solidary economy
Authors: Egorov Vladimir , Inshakov Andrey , Nogmova Adelina , Aleksandrova Elena
Published: October 2023

The global economic system, as well as the planetary civilization, as a whole are experiencing an era of "great changes". The transition is overdue from an economy based on the paradigm of "economic man" — calculating, selfish, competitive, striving to maximize profits — to a regenerative one, based on solidarity and cooperation, built into natural cycles and focused on the welfare of the majority. The solidary economy (SE), which is replacing the existing one, is at the same time a transition to a future regenerative economic system. Its positioning is due to the fact that its institutional design consists of forms of organization integrated into the late modern, but whose potential in terms of prospects for social development goes beyond its limits, crossing the border separating modernity from postmodernity. SE can be understood as an ecosystem of practices that already exist — some old, some new, some still emerging. International organizations consider the solidary economy to be the key to implementing the paradigm shift envisaged by the UN Agenda for the period up to 2030 and achieving the Sustainable Development Goals (SDGs). The key understanding of the SE as a system produced by the evolution of the modern economic system, which does not presuppose its revolutionary replacement with forms that constitute an alternative to existing institutions, the authors drew to its description the cooperation that best meets the needs of the transition to a new quality of socio-economic organization
Non-typical forms of employment in the context of sustainable development of the Russian economy
Authors: Rybak Svetlana
Published: October 2023

The author has chosen the problem of differentiation of civil law and labour contract and the peculiarities of their application in practice in conditions of atypical employment of a certain part of the population as the object of research. The problem considered by the author acquires a completely new understanding in the light of the development of market relations and the emergence of atypical forms of employment. The objective of the study is to identify controversial provisions in the distinction between civil law and labour contracts in the context of the development of atypical forms of employment in Russia. The article is based on such methods of scientific research as comparative-legal, system analysis, formal-legal, and statistical. Distinguishing between civil law and labour contracts, the author draws attention to the fact that the inclusion in the Labour Code of the Russian Federation of norms regulating the work of the self-employed, who have formalized relations with the client under a civil law contract, may violate the unity of labour law, which, although it establishes the specifics of regulating the work of certain categories of workers, but in general applies to absolutely all employees under employment contracts. It seems that the status of the self-employed needs a more thorough legislative elaboration, which will allow, firstly, to increase the level of social protection of this category of citizens, and, secondly, to create conditions for further reduction of the level of informal employment in Russia. The author states that the legal status of the self-employed is poorly developed, which currently gives rise to a huge number of questions in practise. Analysis of court practise clearly demonstrates the fact that Russian courts still do not have a unified approach to resolving disputes on the reclassification of civil-law relations into labour relations

Published: October 2023

The article explores the areas of strategic conflict management that contribute to improving the efficiency of enterprises operating in the agro-industrial complex. There have been used methods of cognition during the study: analysis, synthesis, concretization and abstraction, classification, grouping, and others. There have been given some definitions of the terms based on the study: strategy, conflict and its elements. There have been studied the stages of conflict development at the enterprise and the main causes of the conflicts. We have compared the approaches to conflicts in the organization, developed a matrix of risks that affect the economic efficiency of the enterprise and selected the main types of interpersonal conflicts at the enterprises for the study. During the study, a direct relationship has been revealed between the frequency of occurrence of conflict situations and the economic efficiency of the enterprise, as a result of which styles of behavior have been developed for the management personnel of economic entities in case of conflict situations. The study has allowed to identify the following problems in conflict management at pilot enterprises: an increase in the number of conflicts between departments; the cause of conflicts is often connected with the shift in areas of responsibility in the performance of duties; ignoring the psychological incompatibility of employees when hiring; selection of compromise or adaptive resolution options. To eliminate the identified problems, the directions of strategic conflict management for pilot enterprises were outlined: the formation of a checklist for diagnosing conflicts; development of a conflict management matrix; use of all styles of behavior in conflict situations; timely response to the emerging conflict situation.

In this article, the stages of formation of theoretical knowledge about the tourist region competitiveness are substantiated by applying methods such as the concept of comparative and competitive advantages, the micro and macro approach, regional systematization of research. Also, the "Model of Competitiveness and Stability of Tourist Regions" created by G. Kruch and B. Ritchie was considered as a conceptual model with a systematic approach to the problem, and studies on determining the tourism competitiveness of countries based on the model were analyzed. It is scientifically substantiated that the country's (macro) tourism competitiveness can be achieved through the introduction of a management system based on the principles of self-management, mutual cooperation, and the consistent improvement of each link in the tourism sector on a 7M scale from bottom to top.

Published: October 2023

A formal sign of the existence of the transport services market is the existence of trade relations in this area. The development potential of the services market directly depends on the effectiveness of regulation of trade in services. Over the past decades, trade in services in general (and transport in particular) has been regulated based on bilateral relations. The purpose of the article is to investigate the features of interaction of economic entities in the field of socially significant services on the example of public passenger transport within the modern business environment and to determine the field of their effective interaction. To achieve this goal, the article examines the essence and features of the business environment as an economic category, as well as the evolution of relations between the state and economic actors in the field of socially significant public passenger transport services. The article reveals the problems of building relationships between the authorities, business structures and society in the process of providing public passenger transport services related to the category of goods of a special nature – socially significant. The research is based on an interdisciplinary approach using methods of logical-structural, situational, and comparative analysis. The obtained results and recommendations can become the basis for decision-making by economic entities in the provision of transport services.
Influence of Ground Ice Content on Thawing Depth Road Base
Authors: Galkin Aleksandr , Pankov Vladimir
Published: October 2023

One of the important parameters that determine technical solutions in the design of roads in the permafrost zone is the depth of thawing of the road foundation soils. The aim of the work was to quantify the degree of influence of the ice content in the soil foundations of roads in the permafrost zone on the depth of their seasonal thawing. For the analysis, we used the classical formula for calculating the thawing depth for bodies of plane symmetry, obtained by solving the single-phase Stefan problem. The results of numerical calculations are presented in the form of 2D and 3D graphs, which make it possible to visually assess the effect of ground ice content and the degree of its change during the road operation period on the depth of thawing of the road foundation. It has been established, in particular, that the degree of change in the depth of thawing at the same value of the increase in ice content in different ranges (for example, from 10 to 20% and from 30 to 40%) for the considered typical case of the ground base of the permafrost zone, decreases by almost 1.3 times. It is shown that the greater the initial ice content of the soil, the lower the degree of decrease in the thawing depth when the ice content changes by a constant value.

Authors: Babenko Liana , Saveliefa Natalia
Published: October 2023

The article is devoted to the development of a high-tech garment using IoT technology for people with disorders of the musculoskeletal system. In particular, the results of creating a prototype of a heat-protective product with the function of monitoring physiological indicators of the organism of a person with disabilities are presented. The aim of the work was to develop and scientifically substantiate a system for monitoring physiological parameters of a person with a disability used in a heat-protective product adapted for being in a wheelchair. The relevance of the research is due to the high demand for specialized clothing with a heat-shielding function for people with disorders of the musculoskeletal system, with the ability to track physiological parameters of the body. In the course of solving the problem, an analysis of scientific papers on this topic was carried out. Modern methods of developing algorithms for fuzzy logic, circuit design, modeling and mathematical statistics have been used. In the process of doing the work, a justification for the use of IoT technology in integration with the garment product is given. The software for the smartphone has been developed to monitor physiological parameters of a human body with disabilities. The scientific development was tested in laboratory conditions, which, in turn, confirmed the effectiveness of the proposed idea. The results obtained in the course of the conducted research can be used in everyday life by people with disabilities, thereby improving their quality of life.
Performance en course à pied et forme des stades
Authors: Aftalion Amandine
Published: October 2023

La course à pied se décline en plusieurs distances que l’on pourra admirer lors des Jeux Olympiques de Paris, avec à la clé de possibles nouveaux records du monde. Et si les stratégies des champions pouvaient devenir accessibles à tous les coureurs ?

Grâce à un modèle qui repose sur un problème de contrôle de la force de propulsion (et donc de la vitesse) afin d’optimiser la dépense énergétique et le temps final, nous déterminons comment les coureurs doivent optimiser au mieux leur rythme afin de réaliser la meilleure performance et proposons d’améliorer la forme historique des stades.
Therapeutische Apherese

Therapie der Nierentransplantatabstoßung

Published: October 2023

Bei der Nierentransplantatabstoßung wird zwischen zellulären und humoralen Rejektionen unterschieden, gemischte Formen kommen vor. Die Indikation zur Therapie sollte bioptisch gesichert werden, da viele Differenzialdiagnosen zu verschiedenen Zeiten nach einer Transplantation unter Umständen andere Therapieansätze erfordern und eine nicht notwendige zusätzliche Immunsuppression Risiken herausfordert. Eine kalkulierte Therapie bis zum Eintreffen des Biopsieergebnisses ist allerdings häufig sinnvoll und muss mit dem individuellem Risikoprofil des Patienten vorher abgewogen und besprochen werden. Für einen Therapiewahl sind hier viele Faktoren ausschlaggebend, die auch zum Teil in den weiteren Artikeln dieser Ausgabe von „Nephrologie aktuell“ diskutiert werden. Für die zellulären Rejektionen ist primär eine Steroidgabe etabliert und häufig erfolgversprechend. Bei unzureichendem Ansprechen werden depletierende Antikörper verabreicht. Ein erfolgreiches Ansprechen ist hier naturgemäß im Vergleich zu Steroidtherapie schlechter, was natürlich auch der jeweils unterschiedlichen Ausprägung der Rejektion mit entsprechenden histologischen Veränderungen geschuldet ist. Während die frühe humorale Rejektion zum Teil behandelbar ist, ohne dass hier viel Evidenz im Sinne von klassischen AMG-Studien vorhanden ist, ist die chronische und chronisch akute humorale Rejektion vor allem im späteren Verlauf nach der Transplantation einer Therapie kaum zugänglich. Therapieversuche der akuten humoralen Rejektion auf niedrigem Evidenzlevel beinhalten hier den Plasmaaustausch oder die Immunadsorbtion zur Entfernung von Antikörpern, wie auch der Einsatz von depletierenden Antikörper und die Gabe von Immunglobulinen. Bei den chronisch humoralen Formen kann eine Immunglobulingabe wiederholt versucht werden. Aktuell werden neue Substanzen aus der Rheumatologie und Hämatoonkologie auf ihre Verwendung in diesen Indikationen getestet. Ob diese zu Verbesserungen führen, bleibt abzuwarten.

Akute Beinischämie: ein Update zu Diagnose und Management
Authors: Busch Hans Lucas , Müller Oliver
Published: October 2023

Die akute Beinischämie ist meist durch einen embolischen Verschluss und/oder durch eine akute Thrombose einer atherosklerotischen Läsion gekennzeichnet. Kennzeichnend ist eine schlechte
Kollateralisierung mit niedrigem Kompensationsdruck. Das Amputationsrisiko kann anhand der Rutherford-Klassifikation abgeschätzt werden. Einschränkung der Motorik und/oder neurologische
Ausfälle gebieten eine sofortige Revaskularisation. Mit modernen Katheterverfahren werden gute primäre Ergebnisse erzielt.
