The article publishes and investigates the materials of the excavations of 1976 and 1980 at the Shestakovo-II burial mound in the Chebulinsky district of the Kemerovo region. The burial monument is ...located in the Achinsko-Mariinsky forest-steppe on the second floodplain terrace of the Kia River near the village of Shestakovo, next to other archaeological sites investigated (the Shestakovo-I settlement, the Shestakovo-II settlement and the Shestakovo i burial mound), which belong to the final stage of the early Iron Age and form a single archaeological cultural and chronological complex Excavation materials are systematized at the level of elements of burial structures, memorial funeral rite, burial method and burial equipment. A comparative analysis of published materials with sources from neighboring territories and the valley of the middle reaches of the Kii River is carried out. It is concluded that the published sources are close to the excavation materials of the objects of the third and fourth stages of the Shestakovo i burial mound, which is a reference site for the Shestakovo archaeological culture of the transitional Tagaro-Tashtyk time in the Achinsk-Mariinsky forest-steppe in 1979. Based on the statement that the Tesin archaeological culture of the 3rd century BC is the middle of the 3rd century in the steppes of the Middle Yenisei is a synchronous Shestakov archaeological culture of the Achinsk- Mariinsky forest-steppe and, taking into account the observations made by various authors about the late creation of similar processes in this region, we model a cultural and chronological development scheme. This suggests that the Shestakov archaeological culture could have function from the 2nd century BC to the 4th century. This model and the analogies given to the materials from the Shestakovo II burial mound allow us to date this monument to the 3rd — 4th centuries and attribute it to the final stage of the development of the Shestakovo archaeological culture. Key words: Achinsk-Mariinsky forest-steppe, finale of the early Iron Age, Shestakovo-II burial ground, Shestakovo archaeological culture
This study describes the successful upgrade of a mechanically pumped CO2 two-phase cooling system in space by designing a new pump module for the Alpha Magnetic Spectrometer-02 on the International ...Space Station. Key factors for mission success are emphasized, including achieving high coolant filling accuracy within 10% of the target and maintaining system stability within ±1 °C. The impact of adding radiators to improve cooling efficiency is examined, and it is found that operating multi-radiators out-of-phase does not significantly affect system reliability. The centrifugal pump design is shown to allow for better lubricant circulation, while the in-house designed controller incorporates protective measures to prevent cavitation, overheating, and over-current. This research advances the understanding of circulation loop systems and their upgrades in space and demonstrates the potential for extending the lifetime of space-borne mechanically pumped two-phase cooling systems.
•First in-space upgrade of a pumped two-phase cooling system.•Quantitative on-orbit fluid transfer achieves 7% accuracy.•Superior system control stability of 1 °C with multiple out-f-phase radiators.•Prolonged mechanical pump lifetime via hardware and software manners.

Properties of discharges in a 2 mm glass Resistive Plate Chamber were investigated using the light amplifier for optical pictures and the digital scope for waveforms of induced pick-up signals. ...Multiple discharges were observed for different tetrafluoroethane-based gas mixtures both in ‘avalanche’ and ‘streamer’ modes. Multiple discharges substantially increase the spatial size of the initial discharge caused by a through-going particle ionisation. Average spatial characteristics and typical optical pictures are presented. Space–time relationships for the streamer do not show any prominent dependence.
The paper substantiates the idea of a National Park on the basis of the unique set of objects of historical, cultural and natural heritage in Kemerovo region, near the village of Shestakovo; the ...scientific concept and the stages of its creation and development are introduced. Shestakovo complex should turned into a museum by highly-qualified specialists.
The paper considers both positive and negative trends in preservation of cultural heritage in present-dayRussia. Despite the changes in the legislation and public policies with regard to cultural ...heritage, generally a few changes have taken place in historic preservation as compared to the previous period.
The author considers the publications and dissertation researches of the past two decades devoted to protection of historical and cultural monuments, published in the new historical conditions of ...contemporary Russia. The new state and public approaches to the understanding of the socio-cultural role of historical and cultural heritage is analyzed.
A small glass RPC filled with Ar/Isob./Freon mixture has been exposed to a UV
laser light. Avalanche and streamer regimes of discharge were reached in a
fixed region of the RPC exited by the UV. A ...dependence of avalanche to streamer
transition process on the laser beam intensity and on the applied high voltage
was studied. Two types of the streamer signal have been observed. Using a CCD
TV camera, pictures on multi-streamer propagation over RPC were obtained.
In 62 patients with angina pectoris of different functional classes, physical stress tolerance has been compared to changes of apexcardiographic variables in the postural test. It has been ...demonstrated that anginal patients have abnormal relaxation velocity and left ventricular filling. Passive volume redistribution test allows one to reveal diastolic myocardial dysfunction, severity of which is related to the degree of coronary insufficiency.
