Dichotomy of the Basic Aspects of the Image of Power in Russia: Traditional and Modern Models
Received 26 October 2018. Accepted 7 June 2019. Published online 1 July 2019.Social and cultural characteristics of any country form a certain image of power in the minds of its representatives. The image of power is treated in this work as a set of perceptions about power, which is determined by the sociocultural specifics of a particular political culture. In this article, I discuss contradictions between the traditional model of the image of power inherent in the Russian political culture and the modern democratic model. A conclusion is made that todayβs Russia is characterised by the reproduction of the traditional model of the image of power

Sub-nanosecond Pulse Generation from a Two-section Laser-thyristor: Theoretical Analysis
We have developed a theoretical model of a two-section laser-thyristor. It is shown that using a 4 Β΅m weakly doped p-base can increase blocking voltage up to 50 V, which makes it possible to generate 2 ns 10 A current pulses. It is demonstrated that the proposed device utilizes passive Q switching to generate high-power short optical pulses that account for up to 80% of output power. By picking the optimal passive section length, we have achieved optical pulses of βΌ30 ps full width at half maximum (FWHM) and βΌ100 W peak power.
Keywords: pulsed laser, semiconductor N-p-N-i-P heterostructure, laser-thyristor, dynamic model of pulsed lase
Cryptic Diversity in Paramecium multimicronucleatum Revealed with a Polyphasic Approach
Paramecium (Ciliophora) systematics is well studied, and about twenty morphological species have been described. The morphological species may include several genetic species. How-ever, molecular phylogenetic analyses revealed that the species diversity within Paramecium could be even higher and has raised a problem of cryptic species whose statuses remain uncertain. In the present study, we provide the morphological and molecular characterization of two novel Paramecium species. While Paramecium lynni n. sp., although morphologically similar to P. multimicronucleatum, is phylogenetically well separated from all other Paramecium species, Paramecium fokini n. sp. appears to be a cryptic sister species to P. multimicronucleatum. The latter two species can be distinguished only by molecular methods. The number and structure of micronuclei, traditionally utilized to discriminate species in Paramecium, vary not only between but also within each of the three studied species and, thus, cannot be considered a reliable feature for species identification. The geographic distribution of the P. multimicronucleatum and P. fokini n. sp. strains do not show defined patterns, still leaving space for a role of the geographic factor in initial speciation in Paramecium. Future findings of new Paramecium species can be predicted from the molecular data, while morphological characteristics appear to be unstable and overlapping at least in some species

Cr/Sc multilayer radiator for parametric EUV radiation in "water-window" spectral range
The results of experimental investigation of parametric radiation generated by 5.7 MeV electrons in a multilayer structure consisting of 100 Cr/Sc bi-layers deposited on a Si[3]N[4] membrane are presented. The multilayer structure was specially created for generation of parametric radiation with photon energy in "water-window" spectral range. First test measurements of angular distributions of radiation have been done and discussed

This paper presents data on the organization and results of the provision of the radiation safety in theΒ period of preparation for the Winter Olympic and Paralympic games in Sochi, 2014. The following topics areΒ overviewed in the paper: allocation of land plots for construction of the Olympic facilities; organization of theΒ sanitary surveillance of the imported equipment, construction materials and designs for the construction of theΒ Olympic facilities; putting the Olympic venues into operation. Dose rate of gamma radiation at all land plots,Β which were allocated for the construction of the Olympic facilities, conformed to the requirements of sanitaryΒ regulations. The average dose rate of gamma radiation was 0.11 ΞΌSv h-1 in the Coastal cluster and 0.14 ΞΌSv h-1Β in the Mountain cluster. The radon fluence rate from the ground surface exceeded the prescribed limit ofΒ 80 mBq m-2 s-1 only at the land plot allocated for construction of the Β«House of receiving official delegationsΒ Β«AchipseΒ» and the Β«House of receiving official delegations Β«PsekhakoΒ» in the Mountain cluster. The maximalΒ value of 188 mBq m-2 s -1 was registered here. The buildings projects for this area included using radonΒ protection measures, which were implemented during the construction.Π ΡΠ°Π±ΠΎΡΠ΅ ΠΏΡΠ΅Π΄ΡΡΠ°Π²Π»Π΅Π½Ρ Π΄Π°Π½Π½ΡΠ΅ ΠΏΠΎ ΠΎΡΠ³Π°Π½ΠΈΠ·Π°ΡΠΈΠΈ ΠΈ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΠ°ΠΌ ΠΎΠ±Π΅ΡΠΏΠ΅ΡΠ΅Π½ΠΈΡ ΡΠ°Π΄ΠΈΠ°ΡΠΈΠΎΠ½Π½ΠΎΠΉ Π±Π΅Π·ΠΎΠΏΠ°ΡΠ½ΠΎΡΡΠΈ Π² ΠΏΠ΅ΡΠΈΠΎΠ΄ ΠΏΠΎΠ΄Π³ΠΎΡΠΎΠ²ΠΊΠΈ ΠΊ Π·ΠΈΠΌΠ½ΠΈΠΌ ΠΠ»ΠΈΠΌΠΏΠΈΠΉΡΠΊΠΈΠΌ ΠΈ ΠΠ°ΡΠ°Π»ΠΈΠΌΠΏΠΈΠΉΡΠΊΠΈΠΌ ΠΈΠ³ΡΠ°ΠΌ Π² Π‘ΠΎΡΠΈ-2014 ΠΏΡΠΈΒ ΠΎΡΠ²ΠΎΠ΄Π΅ Π·Π΅ΠΌΠ΅Π»ΡΠ½ΡΡ

Vibromonitoring is the most methodologically developed and technically equipped with recording tools and data processing approach. However, in the sources of scientific and technical information about mining it is presented much less than other monitoring methods. One of the promising ways to solve this problem, in particular monitoring the breakage of cutting disc cutters of an executive body, is to use parameters of natural oscillations of the parts of gearboxes that occur during impulse loading due to such breakages. It should be noted that in the technically complex equipment of the mining industry, in particular in mining machines, there are many sources of vibration, the vibtaions of which are superimposed on each other. And it is not always possible to isolate and identify the required informative signal with the source. With this in mind the paper presents a research methodology on the possibility of monitoring the breakage of the executive body cutters on the example of the continuous miner βUniversal 600β according to the parameters of natural vibrations of the executive body cutting discs arising from the breakage of the cutters. The place of registration of these vibrations is determined β the gearbox handles, on the output shafts of which cutting discs are placed. The frequency of such vibrations is set equal to ~5 Hz. The possibility of using the AGAT-M vibration analyzer with M/AC102-1A vibration sensors as a means of further research has been substantiated in the paper. The paper considers an option of placing vibration sensors on non-rotating gear housings of the executive body drive. An algorithm for recording vibration parameters has been developed, which makes it possible to separate its sources.ΠΠΈΠ±ΡΠΎΠΌΠΎΠ½ΠΈΡΠΎΡΠΈΠ½Π³ β Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ ΠΌΠ΅ΡΠΎΠ΄ΠΈΡΠ΅ΡΠΊΠΈ ΡΠ°Π·Π²ΠΈΡΡΠΉ ΠΈ ΡΠ΅Ρ
