A self-synthesized origin for heavy metals in hot subdwarf stars
Authors: Battich T. , Miller Bertolami M. M. , Serenelli A. M. , Justham S. , Weiss A.
Published: November 2023

Context.A number of He-rich hot subdwarf stars present high abundances for trans-iron elements, such as Sr, Y, Zr, and Pb. Diffusion processes are important in hot subdwarf stars and it is generally believed that the high abundances of heavy elements in these peculiar stars are due to the action of radiative levitation. However, during the formation of He-rich hot subdwarf stars, hydrogen can be ingested into the convective zone driven by the He-core flash. It is known that episodes of protons being ingested into He-burning convective zones can lead to neutron-capture processes and the formation of heavy elements.

Aims.In this work, we aim to explore, for the first time, whether neutron-capture processes can occur in late He-core flashes taking place in the cores of the progenitors of He-rich hot subdwarfs. We aim to explore the possibility of a self-synthesized origin for the heavy elements observed in some He-rich hot subdwarf stars.

Methods.We computed a detailed evolutionary model for a stripped red-giant star using a stellar evolution code with a nuclear network comprising 32 isotopes. Then we post-processed the stellar models in the phase of helium and hydrogen burning using a post-processing nucleosynthesis code with a nuclear network of 1190 species, which allowed us to follow the neutron-capture processes in detail.

Results.We find the occurrence of neutron-capture processes in our model, with neutron densities reaching a value of ∼5 × 1012 cm−3. We determined that the trans-iron elements are enhanced in the surface by 1 to 2 dex, as compared to initial compositions. Moreover, the relative abundance pattern [Xi/Fe] produced by neutron-capture processes closely resembles those observed in some He-rich hot subdwarf stars, hinting at a possible self-synthesized origin for the heavy elements in these stars.

Conclusions.We conclude that intermediate neutron-capture processes can occur during a proton ingestion event in the He-core flash of stripped red-giant stars. This mechanism offers a natural channel for the production of the heavy elements observed in certain He-rich hot subdwarf stars.

Published: November 2023

Congenital heart disease (CHD) is a fairly common pathology of the cardiovascular system, which is the main cause of death in children in the first year of life. The frequency of CHD is 30% of all malformations. The number of HPUs in our country is increasing by 3-4% annually. In Russia, every 125 newborns have one with congenital heart disease or blood vessels. At the same time, in one out of 200 newborns, congenital malformations of the heart and blood vessels are of a combined nature, that is, they occur in various combinations, and, therefore, have a more severe clinical course. The main function of the cardiovascular system is the delivery and provision of oxygen and nutrients to all organs and tissues, as well as the reverse transportation of carbon dioxide and metabolic products. With each contraction, the heart normally ejects 70-120 ml of blood (stroke volume). The minute volume of the heart (the amount of blood ejected by the left ventricle in 1 minute) is normally 5500-7000 ml / min. And it largely depends on the height and weight of the person.

Authors: Abumuslimov Saidhamzat , Shakhgirieva Zlata , Sirieva Yakha
Published: November 2023

The study of heart rate variability parameters in adolescent children was carried out. Heart rate, cardiac cycle duration and several parameters of rhythmic activity of the heart at rest and after a short-term exercise test were studied. It was found that in adolescent children short-term physical load causes statistically significant changes in almost all studied parameters of cardiac activity. One of the most important indices characterising the rhythmic activity of the heart, the stress index in adolescents after motor exercise increased significantly. Its values indicate an increase in the activity of the sympathetic link of the autonomic nervous system after the load. At the same time, the values of the stress index of heart rate variability after the load did not exceed the values characterising overstress in the central nervous mechanisms of regulation of rhythmic activity of the heart.

The article analyzes the results of growing new planting materials by tissue culture of some medicinal plants (Eminium regelii Vved., Angelica ternate Regel et Schmalh., Aconitum rotundifolium Kar. et Kir., Gentiana algida Pall., Rodiola heterodonta (Hook. f. et Thomson) Boriss.), found on the territory of the natural park Kara-Shoro of Kyrgyzstan. The conditions for growing callus cultures by the in vitro method were studied and the temperature optimum for growing cell cultures in the laboratory was identified. Callus cultures were grown on four types of nutrient media, which differ from each other in their component composition, and the preparation technique is the same.In the course of the study, it was found that the most universal nutrient medium is the Murashige-Skoog medium, in which callus formation is relatively more observed. The nutrient medium of Nitsch and Nitsch showed the lowest indicators of crop survival. Gamborg’s and Eveleg’s media showed good results, but root formation proceeded comparatively faster in White’s nutrient medium. Planting schemes for medicinal plants and conditions for growing and development close to the ecological optimum have been developed. Based on the studies carried out, methods were proposed for creating a research and production complex for growing cell cultures of the State Natural Park (SNP) Kara-Shoro.

Carbon landfills: On the way to carbon neutrality
Authors: Kudusov Islam , Satueva Laila , Bankurova Raisa
Published: November 2023

The development of the bioeconomy is driven by integration, which takes various forms. Natural integration involves business mergers and the creation of diverse organizational relationships, including conglomerates, transnational companies, and cartels, among others. Conversely, disintegration and quasi-integration entail the unbundling of businesses and the formation of formal associations, where the aim is to gain control over other business entities rather than acquiring their assets. An example of quasi-integration can be observed in enterprise clusters, which are groups of geographically localized and interconnected companies sharing common goals and strategies. While the advantages of company participation in clusters were evident at the end of the 20th century, it has become apparent by the early 21st century that integration interactions among companies are assuming new hybrid forms. Consequently, clusters themselves can undergo various transformations over a short period of activity.

The development of the bioeconomy is driven by various forms of integration. Natural integration involves business combinations and various organizational interactions, such as concerns, transnational companies, and cartels. Disintegration and quasi-integration occur when businesses unbundle, and formal associations are formed with the aim of acquiring control rather than assets of other business entities. Enterprise clusters are a typical example of quasi-integration. These clusters consist of geographically localized and interconnected companies with shared goals and strategies. While the benefits of participating in clusters were evident at the end of the 20th century, it has become clear by the early 21st century that the integration of companies is taking on new hybrid forms, and clusters themselves can undergo significant transformations over a short period. The bioeconomy is widely recognized as a promising approach to conserve Earth’s energy resources. Its main objectives include the development of alternative energy sources, improved energy efficiency, efficient waste utilization, the promotion of renewable energy derived from biomass, greening the industrial sector, enhancing the sustainability of agriculture, producing new food products, advancing medical technologies, and utilizing biotechnologies based on renewable biological raw materials.

Authors: Stozhko Dmitry , Stozhko Natalia
Published: November 2023

The purpose of the study is a comparative analysis and assessment of the current environmental situation against the background of the global environmental crisis and constantly growing turbulence, uncertainty and environmental risks. The article reveals the humanitarian context of modern environmental risks caused by extensive industrial production, the cult of consumption and wastefulness that has lasted for many decades. The resulting “consumer society” brought the situation to a global environmental crisis and transferred itself into a “risk society.” In this regard, the article raises questions about the purposeful formation of environmental culture and improvement of the regulatory framework of environmental legislation, the development of environmental consciousness and environmental psychology. It is noted that economic or technical and technological tools alone were clearly not enough to overcome negative processes in the environment. The main condition for the implementation of the author's proposals is the rejection of wastefulness and so-called false needs in favor of frugality and moderation in the consumption of natural resources.

Published: November 2023

The paper highlights the issues of spatial development of Russia's territory and its regions. The authors substantiate the interrelation of spatial development and sustainable development of territories, where the spatial organization of the country's economy is considered as one of the directions of achieving sustainable development. The problems of spatial development are analysed and disclosed. As an important indicator of the imbalance of modern spatial development of regions and the whole territory of the Russian Federation is considered the population density and concentration of economic activity, which have a close relationship and historical features of formation. The paper substantiates the allocation of macrozones and macroregions for a comprehensive analysis of social and economic problems and determining the prospects of spatial development of the Russian Federation regions. Statistical indicators in the context of six macrozones are given and analysed. The authors substantiate the allocation of macrozones from the position of the theory of economic zoning of the territory of Russia, which was applied before 2000, and the formation of Federal Districts as a result of the introduction of a new political and administrative reform of the country. The authors identify the regularities of development of six macrozones based on the results of analysing a sample of statistical indicators and trends in their dynamics. The study formulates and substantiates the problems of persisting imbalance and disproportions in the spatial development of Russia's regions and territory. In order to solve this problem, the authors propose a multilevel realization model of spatial development of the territory the Russian Federation, in which the criteria of differentiation are defined at the following levels: macro-level and meso-level. The basis for solving the problems of spatial differentiation is the choice by each region of a clear strategy of socio-economic development, the development which is fixed at the state level and is mandatory.

The relevance of the article is due to the need to develop sustainable development competencies when training specialists in the field of physical culture and sports. A responsible attitude towards the environment, social issues and economics allows graduates to actively participate in solving the problems of the modern world. The purpose of the article is to determine the elements of the educational program that form the competencies of sustainable development during training in specialties in the field of physical culture and sports. The main research method is correlation-regression analysis, using as a result indicator the number of students who received an “excellent” grade in disciplines that form sustainable development competencies, and as factor indicators characterizing the completeness of the educational program. As a result of the assessment, the overall significance of the identified factors for the formation of sustainable development competencies in the training of specialists in the field of physical culture and sports was obtained in the range of average values - 0.36. Correlation analysis showed that the indicator “Number of practical, laboratory, seminar classes hours” has the greatest connection with the formation of sustainable development competencies - 0.48, which characterizes the importance of students’ personal motivation to master areas of training in the field of physical culture and sports. In the range of the average level of connection with a high level of sustainable development competencies are the factors “Number of full-time hours” - 0.45, “Number of student independent work hours” - 0.48 and “Number of practice hours” - 0.41.

The study is focused on evaluating the effectiveness of integrating virtual reality (VR) with the principles of chemistry education (CE) in order to improve students' understanding of chemistry. A mixed method approach, including literature review, empirical research, and analysis of VR sessions, was used to identify the impact of VR on students' conceptual understanding and motivation. The results confirmed that VR integration significantly increases conceptual understanding and student engagement. VR provides interactive and practice-oriented learning, breaking the abstraction of chemical concepts. The approach also highlights the need to rethink traditional pedagogical methods in favor of active, contextualized learning. Emerging issues, including equity of access and job training, require attention to successfully integrate VR into education.

Nowadays ecological or «green» tourism is an actual direction for the natural and recreational territory potential development. Ecotourism is able to provide the sustainable development as certain regions and in the Russian Federation as a whole. The difficulties connected with the ecotourism formation and organization reveal the need in new decisions for the creation of the comfortable eco-touristic space for the customer at the current stage of the economic development. Novosibirsk region has a rich natural and recreational potential and consider as perspective territory for the ecotourism formation and development. The region has favourable temperate continental climate, developed hydrographic network, presence the attractive natural objects including specially protected natural areas (SPNA). It is necessary to position the region as a new eco-touristic destination and implement by stages the best practices of the eco-oriented tourism. The main goal of the study is to analyze and estimate the touristic and recreational potential of the Novosibirsk region to justify the ecotourism development directions in the region. This study is characterized and presented by the analysis of the natural and recreational potential of the Novosibirsk region for the ecotourism development. The estimation of the regional climate conditions and natural resources is conducted. The most attractive districts for the ecotourism development are defined. The author proposes the districts’ specialization by subtypes of the eco-oriented tourism that need to takes into account the determination of the touristic territory development trajectories.

Double-differential cross section (DDX) data on the neutron-induced emission of light charged particles are required for assessing the risk of secondary tumors in particle radiation therapy. There are only very few DDX data available for discrete neutron energies close to and above 100 MeV for carbon. A measurement of DDX on carbon is planned at continuous neutron energies from 20 MeV to 200 MeV with particle detector telescopes at n_TOF (CERN). Several detector development criteria and challenges are reported such as coincidence timing and electromagnetic oscillations for high neutron energy events with particle separation.

As part of the activities for developing experimental devices for research reactors and associated test loops, some concern the development and qualification of instrumentation.

The on-board instrumentation makes it possible to monitor online the evolution of physical parameters of samples and/or components subjected to different stresses (thermal, hydraulic, chemical and nuclear, etc.).

In addition to the so-called “classic” instrumentation implemented in this type of equipment (pressure, temperature, flow, elongation), R&D actions are in progress in order to propose innovative instrumentation, able to improve the experimental offer and describe the physical phenomena with more accuracy.

This is the case of optical measurements which present many advantages (compactness, insensitivity to EM waves, complex measurements by optical interrogation of a single fiber).

In addition, actions are underway for the selection of optical fibers that can be used for applications in a nuclear reactor (in particular resistance to the irradiation).

The tests presented in this paper relate to the behavior of sealed feedthroughs for optical fibers to the thermal hydraulics conditions of light water reactors.

These tests are part of the safety demonstration in so-called degraded operating cases i.e. corresponding to a configuration where the optical fiber is placed directly in the process fluid (pressurized water). One note that in normal operation, the optical fiber is isolated from the process fluid by a jacket consisting of a metal capillary.

After an introduction and a brief presentation of the use of optical fibers in experimental equipment, the paper describes the tightness feedthroughs used, the tests carried out, indicate the main results obtained and opens up some perspectives for future development phases.
