The migration of point defects in metals contributes to the transfer of mass and energy during plastic deformation, heat treatment, irradiation, etc. In this regard, the study of such physical processes of nonlinear dynamics of the crystal lattice of metals is an urgent task. In this paper, the dynamics of 2-crowdion and the processes of energy transfer in tungsten are studied, aimed at understanding the mechanisms of defect formation and energy dissipation under extreme temperatures and pressures. It is known that crystal lattices accumulate a large number of defects under external influence, such as vacancies, dislocations, and grain boundaries. All these defects create internal stress fields that will affect the dynamics of crowdions. Using the methods of molecular dynamic modeling and embedded atom model, the propagation of 2-crowdions in a three-dimensional structure was studied. The main results show that the formation of 2-crowdions occurs at critical values of the excitation energy and depends on the initial configuration of the system, where 2-crowdions initiate chain processes of energy transfer through the atomic lattice. It is revealed that the depth of passage of the 2-crowdion linearly depends on the magnitude of the initial energy. The obtained spatiotemporal characteristics of the energy distribution demonstrate the role of 2-crowdions in the local concentration of energy and its subsequent transfer through atomic bonds, which leads to the formation of point defects. These results are important for the design of new radiation-resistant materials, as they help predict the material’s resistance to high-energy influences. The work contributes to the understanding of the physical foundations of energy dissipation and the behavior of defects in refractory materials used in thermonuclear fusion and other high-temperature processes.

The recent failure of attempts to extract the rotational energy of the Earth by unipolar induction methods suggests a need for further research on unipolar induction. It is implied by the special relativity theory that the interaction of electric charge and magnet in unaccelerated motion depends only on the relative rate. The electromotive force of unipolar induction in a complete electrical circuit depends only on the relative rotation of the magnet and the connected through slide contacts voltmeter. To ascertain if the electric field resulting from the magnet’s rotation in an inertial frame of reference or in a frame of reference rotating in a magnetic field is the result of absolute or relative rotation, it is necessary to measure the field. For this purpose, the paper introduces the experiment with the relative rotation of a ring-shaped magnet and a cylindrical capacitor. The capacitor is permanently connected through sliding contacts to the electrostatic meter. The electrostatic meter detects the potential difference on the capacitor while the magnet or capacitor is being rotated. The measurements showed that the potential difference on the capacitor is depends not on the capacitor rotating in case of a stationary magnet or a magnet rotating while the capacitor is stationary. It is close to zero when the capacitor rotates with the magnet. According to the research results, the interaction of the electric charge and magnet in the nonrelativistic case depends on the relative rotation rate. This interaction is described by the Lorentz formula.

The article considers the potential for fuel and energy savings through the integration of heat pump units (HPUs) into the existing thermal power generation scheme of the Yakutsk combined heat and power plant (CHP). Currently, one of the promising energies saving technologies is heat pump units (HPU). The Yakutsk CHP, with a total thermal output capacity of 450 Gcal/h, currently relies on five hot water boilers: two KVGM-100 units, two PTVM-100 units, and one PTVM-50 unit. According to the United Cycle (UC) program, a thermal scheme simulation was conducted to assess the impact of incorporating HPUs. The study examined two operational modes: (1) with HPU operation and (2) without HPU operation. Heat load calculations were performed for both modes, analyzing boiler operation and HPUs' performance. The results demonstrate that integrating HPUs into the thermal scheme leads to a reduction in boiler plant. When preheating return mains water at 10°C, the HPUs achieve a thermal load of 55.6 Gcal/h, representing 12.3% of the total heat generation capacity. The article determined that by employing HPUs for boiler unloading, fuel consumption can be reduced by 12.4%. These findings highlight the effectiveness of integrating HPUs into the Yakutsk CHP scheme, presenting a viable approach to improving fuel efficiency and reducing operational costs.

The Yana River basin in the Yana-Indigirka Lowland is one of the richest regions of Yakutia in paleontological finds of animals representing the mammoth fauna with soft tissues. More than 130 years ago, a large collection of paleontological material was collected by the royal expedition led by A. A. Bunge and E. V. Toll (1885-1886), which is stored in the storerooms of the Zoological Institute of the Russian Academy of Sciences in St. Petersburg. Previously known unique finds on the middle reaches of the Yana River included the Lena horse body fragment (2009), juvenile bison (2009), collared lemming (2012), and Verkhoyansk foal (2018) discovered at the Batagaika location. In 2023, during field work, paleontological and palynological material was collected at the main locations of the Yana River basin. New data on the quantitative and percentage ratio of mammoth fauna species at the Khaastaakh locality are presented, as well as some morphometric indicators for a fragmented fossil bison body. For a comprehensive study of the localities, various methods of paleogeographic reconstructions were used, including paleontological, palynological and radiocarbon analyses. These methods were aimed at identifying temporal patterns of variability of natural conditions at the Pleistocene-Holocene boundary. The results of the latest findings supplement the information on the distribution of representatives of the mammoth fauna in the territory of Yakutia in the late Pleistocene and Holocene.

A limited number of scientific publications are devoted to the analysis of small mammal communities in North-East Yakutia, which does not allow us to estimate their previous abundance and distribution across biotopes in the upper reaches of the Indigirka River. Research on this topic in 2023 made it possible to obtain new, unique data on the state and abundance of game species and small mammals in the Oymyakon ulus (district) of the Republic of Sakha (Yakutia) in valley biotopes. The purpose of the work was to determine the biodiversity of mammals in the floodplain lands of the upper reaches of the Indigirka River. Research in the Oymyakon ulus (district) of the Republic of Sakha (Yakutia) was carried out in March-July 2023 in lands adjacent to one of the depleted gold deposits on the Bolshoy Taryn River, which is a right tributary of the Indigirka River. According to literary sources, 17 game species of mammals live in the study area. In 2023, three routes with a total length of 19.4 km were completed, on which traces of eight species were recorded. In the process of analyzing the trace activity of wild animals registered during the winter route surveys, it was found that traces of small animals (squirrel, ermine, Arctic hare, fox) were found in the immediate vicinity of the infrastructure facilities of the developed deposits. Traces of large, more anthropomorphic animals (elk, wild reindeer) and sable were recorded at some distance from industrial facilities. It was shown that the current population density of game species living in the floodplain of the Bolshoy Taryn River is within the limits of the official data of the Hunting Department of the Ministry of Ecology of the Republic of Sakha (Yakutia) for the Oymyakon ulus (district). This indicates the absence of a significant impact of industrial facilities on game species. To assess the biodiversity of small mammals using standard methods, 40 specimens were captured. During the capture period, 600 trap-days and 72 cone-days were processed. The Shannon diversity index for the small mammal community was 1.262. This shows the low biodiversity of small mammal species from the Insectivora and Rodents orders, which is explained by the peculiarities of the natural conditions of the area. The second reason for the small number of captured species, compared with those caught earlier in the middle reaches of the Indigirka River, is the fact that the capture of small mammals was carried out almost only in the valley of the Bolshoy Taryn River.

The study deals with the history of exploration of the subsoil resources of the Sakha Republic (Yakutia), its huge and diverse geological and mineralogical potential. The authors analyse the existing museums devoted to geology and mineralogy, and put forward the idea of the necessity to create a large museum reflecting the history of geological exploration and development of mineral resources in the republic. The urgent need to create a mining and geological museum in Yakutsk, reflecting the history of geological exploration and development of mineral resources in the republic is emphasised. The concept of the museum as a powerful centre of scientific and educational education and a space of cultural exchange of society, based on axiological basis, is defined. Its mission as propaganda and popularisation of knowledge about the Earth, preservation of unique geological fund of the republic, orientation and self-identification of the person in the world of values is characterized.
