Anti-terrorist activities of the future officers: essential and structural specifications

The issues of the fight against terrorism and the training of law enforcement personnel to participate in this fight are currently particularly relevant. This is due to the fact that on the one hand, terrorism evolves and builds its activities taking into account the anti-terrorist policy, on the other hand, international terrorism has long ceased to be a «thing in itself», it is actively but covertly used by many countries and political forces to gain benefits and achieve their goals. The article examines the characteristics of anti-terrorist activities and the conditions in which their skills are formed. The research methodology is based on the system and activity approaches and functional analysis. The main scientific results of the study were that the characteristics of the anti-terrorist activities of future officers were revealed and the structure of readiness for this activity was clarified, the pedagogical conditions for the formation of the readiness of future officers for anti-terrorist activities were given, the optimization of the educational process was modeled in order to form the readiness of future officers for anti-terrorist activities

Structural features of Fe-Al-vacancy system

The influence of structural defects on phase transformation in Fe-Al-vacancies system is considered. It has been shown that, due to existing trend to accumulation of point defects at increasing aluminum content in Fe-Al system alloys, the appearance of ferrite precipitates in Fe₃Al compound becomes thermodynamically favorable in the temperature region of the equilibrium α₁(Fe₃Al)-phase existence.Розглянуто вплив дефектiв структури на перебiг фазових перетворень у системi Fe-Al-вакансil. Показано, що внаслiдок iснуючої тенденцiї накопичення дефектiв структури зi збiльшенням вмiсту алюмiнiю у сплавах системи Fe-Al в iнтерметалiдi Fe₃Al в областi температур iснування рiвноважноl α₁(Fe₃Al)-фази термодинамiчно вигiдним стає поява видiлень фериту.Рассмотрено влияние дефектов структуры на протекание фазовых превращений в системе Fe-Al-вакансии. Показано, что вследствие существующей тенденции накопления дефектов структуры по мере увеличения содержания алюминия в сплавах системы Fe-Al, в интерметаллиде Fe₃Al в области температур существования равновесной α₁(Fe₃Al)-фазы термодинамически выгодным становится появление выделений феррита

Anisotropic cosmological models in terms of Raychaudhuri and Wheeler-DeWitt equations

Classical anisotropic cosmological models are described in terms of the Raychaudhuri equation for a perfect fluid. Quantum ones are considered using the Wheeler-DeWitt equation. The Universe birth probability has been calculated for a flat model with dust and de Sitter vacuum. © 2009 Pleiades Publishing, Ltd

Migration Aspect in the Oil-Bearing Capacity of the Domanic Formation in Tatarstan

The article highlights the problem of oil bearing of the Domanic Formation on the territory of the Republic of Tatarstan. Comparing the geochemical characteristics of bitumen of the Semilukskian horizon and oils of the Eifelian-Frasnian terrigenous complex, it was concluded that in the Semilukskian horizon, mobile bitumen are present along with the syngenetic dispersed matter, which, according to gas-liquid chromatography, are identical to the oil of the underlying terrigenous deposits of the Pashian and Timanian horizons. These bitumens are migratory and reflect the process of upward vertical oil migration, which is responsible for the formation of industrial deposits in the Semilukskian, Sargaevskian, and Rechitskian horizons in those areas where the lithological features of the rocks and the development of superficial fracturing in them make it possible to create a collecting space. The rocks of the Domanic facies should be considered as accumulation or accumulation-generation system, oil deposits of which were formed due to oil systems generated in other sources. New methods of search are needed that allow us to quickly assess the content of migratory hydrocarbons and syngenetic organic matter. This is possible on the basis of a rapid study of the sludge, which will allow to assess the presence of mobile hydrocarbons and their quantity during drilling. An analysis of the spatial distribution of migratory hydrocarbons will allow localizing oil migration channels

NMR resonance assignment and backbone dynamics of a C-terminal domain homolog of orange carotenoid protein

© 2020, Springer Nature B.V. Photoprotection in cyanobacteria is mediated by the Orange Carotenoid Protein (OCP), a two-domain photoswitch which has multiple natural homologs of its N- and C-terminal domains. Recently, it was demonstrated that C-terminal domain homologs (CTDHs) of OCP are standalone carotenoproteins participating in multidirectional carotenoid transfer between membranes and proteins. Non-covalent embedment of a ketocarotenoid causes dimerization of the small 16-kDa water-soluble CTDH protein; however, dynamic interactions of CTDH with membranes and other proteins apparently require the monomeric state. Although crystallography recently provided static snapshots of the Anabaena CTDH (AnaCTDH) spatial structure in the apo-form, which predicted mobility of some putative functional segments, no crystallographic information on the holo-form of CTDH is presently available. In order to use NMR techniques to cope with the dynamics of the AnaCTDH protein, it was necessary to obtain 1H, 13C and 15N resonance assignments. AnaCTDH samples enriched with 13C and 15N isotopes were prepared using recombinant protein expression, and NMR resonance assignment was achieved for more than 90% of the residues. The obtained results revealed that the structure of AnaCTDH in solution and in the crystal are largely equivalent. Together with 15N NMR relaxation experiments, our data shed light on the AnaCTDH dynamics and provide the platform for the subsequent analysis of the holo-CTDH structure in solution, for the better understanding of light-triggered protein–protein interactions and the development of antioxidant nanocarriers for biomedical applications in the future
