Purpose. The dwelling, as one of the basic elements of the life-support system, more and more often is becoming a focus of researchers’ interest when they excavate archaeological sites where Russian population lived during the New Age in Siberia. On the basis of materials obtained from the excavations, various types of reconstruction are carried out, including 3D models. Written and ethnographic sources are used to create such models as comparative materials. Results. The sources studied give information about the area of the buildings, but indicators of the possible height of these constructions in the 17th – 18th centuries remain hypothetical. Our material is based on representative ethnographic information and archaeological materials on the dwellings of Russian population in the Irtysh River area near Tara, Mangazeya and Sayan ostrog. We used published written sources that contained information about probable height characteristics of dwellings during the 17th – 18th centuries, made our calculations and created 3D models of dwellings, which were analyzed. Conclusion. The main conclusion drawn from the results of our work is that the accuracy of reproduction of certain properties of the original object while making a 3D model should be based not only on the search for analogues, but also take into account the cultural landscape surrounding the object in the studied period of time.

Bird hunting as a type of economic activity of the Russian population in the 17th—18th centuries is analyzed on the basis of archeozoological collections and complexes from the cultural layers of rural sites. The composition and ratio of different types of commercial birds, methods of passive and active hunting are determined. The results obtained are compared with written sources of the 19 th century and archaeological materials from other regions. As part of the inventory of archaeological sites, in addition to the bow and arrowheads, a set of clay balls of different sizes and weights was identified, which were used as projectiles for slingshot in hunting flocking birds.

<p><strong>Abstract.</strong> 3D reconstruction and virtual reality (VR) technology provide many opportunities for the documentation and dissemination of underwater cultural heritage. Advances in the development of underwater exploration technology have allowed for the first time to accurately reconstruct a complete 3D model of the cargo Río Miera in the Cantabrian Sea. Sunk on December 6, 1951 after a strong collision, the cargo ship Río Miera rests on a sandy bottom about 40 meters deep, very close to the Cantabrian coast. Located in an area of strong currents is a classic objective of the region for the most experienced divers. The survey was carried out this summer in R/V Ramón Margalef of the IEO, acquiring acoustic data with multibeam echo sounders and hundreds of images acquired by a remotely piloted underwater vehicle. The campaign is part of the PhotoMARE project - Underwater Photogrammetry for MArine Renewable Energy. This work describes the workflow regarding the survey, images and acoustic data acquisition, data processing, optic 3D point cloud color enhancement and acoustic and optic dataset merging procedure to obtain a complete 3D model of wreck Río Miera in Cantabrian Sea. Through this project, Spanish Institute of Oceanography – IEO have advanced – combining acoustic and image methods - in the generation of 3D models of archaeological sites and submerged structures.</p>

Abstract. Archaeological sites in urban areas are often poorly integrated with the modern urban fabric and appear as “trenches” at a lower level than the road. They become neglected and unvalued places. The study of archaeological ruins in urban centres must involve archaeologists and architects to integrate restoration, enhancement and improvement of physical and visual accessibility projects. New digital technologies can improve these activities thanks to 3D models, “digital replicas” that allow even remote study (especially during a pandemic). The paper presents the case study of a private Roman-imperial bath in Catania. The open-air site is located at a depth of 3 metres above the road level and is not exploited. Our study consisted of historical-bibliographical research, direct and SfM surveys that allowed creating a high-resolution textured 3D model. We have extracted orthophotos and sections for geometric and technical-constructive analyses and recognition of decay from this model. We drew up an archaeological restoration and valorisation design. In addition, we imported the model into the Sketchfab portal. So, we enriched the mesh with information from the analyses employing specific tags about annotations, 2D drawings, historical and technical-scientific information. In this way, the model becomes an interactive document to monitor over time the conservation state, validate the restoration design and contribute to the valorisation of the site. This is an easy tool of exchange between all involved users (researchers, professions and students). Thus, the digital replica also represents a very high potential for dissemination purposes.

The article analyzes the problems of the manifestation of risks of shadow and criminal activity in the life support system of citizens of the Russian Federation, the dissemination of which requires the development of effective measures to prevent and eliminate them. The most important issue is the formation of an effective economic security system with an emphasis on the new quality of life support for citizens of the Russian Federation in an adequate combination with the high growth rate of NTP in the Russian economy. The new technological structure emerging from the new achievements of scientific and technological progress involves the harmonization of the pace of scientific and technological development, combined with an adequate improvement in the quality of life support for citizens performing such achievements. Owing to this fact formation of new quality of the housing and communal services (HCS) as bases of life support of citizens becomes a prerequisite of increase in performance and intellectualization of human work. With this in mind, early recognition, prevention and elimination of risks of shadow and criminal activities in the housing and communal services system (housing and communal services) is considered as a significant mechanism to increase the effectiveness of the system of comfortable life support for citizens of the Russian Federation. The existing lag in the development of a high-quality and comfortable system for providing citizens of Russia on the basis of housing and communal services, the subject of which is the provision of quality and comfortable services, influenced by numerous risks of shadow and criminal influence, becomes a condition for intensifying economic development and increasing labor productivity on this basis. The need to develop and use modern scientific and technical achievements, especially in the field of digitalization, is emphasized in order to increase the efficiency of the economic security system of housing and communal services organizations based on innovative control mechanisms - internal control, audit, compliance control, taking into account financial investigations in order to prevent and eliminate the risks of shadow and criminal activities in the housing and communal services system.

Analysis and calculation have been conducted of the process of low-pressure reverse osmosis in the membrane apparatus of the system for recycling hygiene water for the space station. The paper describes the physics of the reverse osmosis treatment and determines the motive force of the process, which is the difference of effective pressures (operating pressure minus osmotic pressure) in the solution near the surface of the membrane and in the purified water. It is demonstrated that the membrane scrubbing action is accompanied by diffusion outflow of the cleaning agent components away from the membrane. The mass transfer coefficient and the difference of concentrations (and, accordingly, the difference of osmotic pressures) in the boundary layer of the pressure channel can be determined using an extended analogy between mass transfer and heat transfer. A procedure has been proposed and proven in an experiment for calculating the throughput of a reverse osmosis apparatus purifying the hygiene water obtained through the use of a cleaning agent used in sanitation and housekeeping procedures on Earth. Key words: life support system, hygiene water, water processing, low-pressure reverse osmosis, space station.

Background: Portable life support system is used in the battlefield, disaster and in other special circumstances such as in space exploration, and underground survey to give the wounded a life support. The most dangerous period for the injured is the first hour after an injury, which is a crucial time for treatment. If the patient's vital signs were stabilized, more than 40% of the injured could be saved. The staff can efficiently complete the task if they get effective and stable vital signs during the operation. Therefore, in order to reduce the risk of disaster and battlefield mortality to improve operational safety and efficiency, it is necessary to study the portable life support system. Objective: The study aimed to provide an overview of recent portable life support system and its characteristics and design. Methods: This paper introduces the patents and products related to a portable life support system, and its characteristics and application. Results: This paper summarizes five kinds of portable life support systems which are box type, stretcher type, bed type, backpack type and mobile type. Moreover, the characteristics of different portable life support systems are analyzed. The paper expounds the problems of different types of portable life support systems and puts forward improvement methods to solve the problems. Finally, the paper points out the future development of the system. Conclusion: Portable life support system plays an increasingly important role in health care. In terms of the structure, function and control, further development and improvements are needed, along with the research on portable life support system.
