PROSECUTOR’S SUPERVISION OVER THE ACTIVITIES OF THE BODIES OF PRELIMINARY INVESTIGATION ON COMPENSATION FOR DAMAGE CAUSED BY A CRIME AT THE STAGE OF INITIATING A CRIMINAL CASE

Aim: The article is devoted to the consideration of the essence and main directions of prosecutorial supervision over the activities of officials of the preliminary investigation bodies for compensation for harm caused by a crime at the stage of initiating a criminal case. According to the deep conviction of the authors, one of the directions for ensuring the rights and legitimate interests of victims of crimes is to ensure compensation for property and physical damage, as well as compensation for moral damage and damage to business reputation. This area of activity of the preliminary investigation bodies is no less important than bringing the perpetrators to justice in order to assign them a fair punishment. Results: The author identified some reasons that negatively affect the implementation of prosecutorial supervision over the activities of these participants in criminal proceedings to ensure compensation for harm caused by a crime at the stage of pre-investigation verification. Conclusion: In conclusion, the authors substantiate the conclusion that at present, prosecutorial supervision over the activities of officials of the bodies of preliminary investigation is relevant and especially in demand to ensure the principle of competitiveness of the parties, the creation of legal guarantees for the realization by persons who have become victims of criminal acts, the right to full compensation for the harm caused. Prosecutorial supervision is proposed to be regarded as an important dominant of the procedural function of prosecutors, aimed at preventing violations in the activities of the preliminary investigation and inquiry bodies to compensate for harm caused by criminal acts, starting from the stage of initiating a criminal case

Electrospun magnetic composite poly-3-hydroxybutyrate/magnetite scaffolds for biomedical applications: composition, structure, magnetic properties, and biological performance

Magnetically responsive composite polymer scaffolds have good potential for a variety of biomedical applications. In this work, electrospun composite scaffolds made of polyhydroxybutyrate (PHB) and magnetite (Fe3O4) particles (MPs) were studied before and after degradation in either PBS or a lipase solution. MPs of different sizes with high saturation magnetization were synthesized by the coprecipitation method followed by coating with citric acid (CA). Nanosized MPs were prone to magnetite-maghemite phase transformation during scaffold fabrication, as revealed by Raman spectroscopy; however, for CA-functionalized nanoparticles, the main phase was found to be magnetite, with some traces of maghemite. Submicron MPs were resistant to the magnetite-maghemite phase transformation. MPs did not significantly affect the morphology and diameter of PHB fibers. The scaffolds containing CA-coated MPs lost 0.3 or 0.2% of mass in the lipase solution and PBS, respectively, whereas scaffolds doped with unmodified MPs showed no mass changes after 1 month of incubation in either medium. In all electrospun scaffolds, no alterations of the fiber morphology were observed. Possible mechanisms of the crystalline-lamellar-structure changes in hybrid PHB/Fe3O4 scaffolds during hydrolytic and enzymatic degradation are proposed. It was revealed that particle size and particle surface functionalization affect the mechanical properties of the hybrid scaffolds. The addition of unmodified MPs increased scaffolds' ultimate strength but reduced elongation at break after the biodegradation, whereas simultaneous increases in both parameters were observed for composite scaffolds doped with CA-coated MPs. The highest saturation magnetization-higher than that published in the literature-was registered for composite PHB scaffolds doped with submicron MPs. All PHB scaffolds proved to be biocompatible, and the ones doped with nanosized MPs yielded faster proliferation of rat mesenchymal stem cells. In addition, all electrospun scaffolds were able to support angiogenesis in vivo at 30 days after implantation in Wistar rats

Optimization of dental implant treatment

Aim ― Modern dentistry cannot exist without dental implantation. The lifetime of the installed implants depends on condition of the bone and on the quality of the treatment planning and surgery technique. Usually, complications during the implant treatment are related to the inability to accurately predict the condition and location of intraosseous structure that entails the selection of the wrong type of implant and installation position. Methods ― This work is devoted to the "bone-implant" system investigation aiming on the optimization of dental prostheses installation. The objective of this study was to develop the implant treatment planning technique. Modern non-invasive methods such as computer tomography (CT) and 3D-scanning as well as numerical calculations and 3D-prototyping allow optimizing all of dental prosthetics stages. Results ― In this work, complex methodology of dental prosthesis installation is presented. Patient-specific dental templates developed in this work are easy to create and very accurate. Conclusion ― CT processing method, numerical modeling and 3D prototyping techniques allowed us to develop a methodology of dental prosthesis installation. An integrated approach to the planning of implant surgery can significantly reduce the risk of complications in the first few days after treatment, and throughout the period of operation of the prosthesis

Detection of Glacial Refugia and Post-Glacial Colonization Routes of Morphologically Cryptic Marsh Frog Species (Anura: Ranidae: <i>Pelophylax</i>) Using Environmental Niche Modeling

Studying the distribution of morphologically cryptic animal species is always a very difficult task. Because most marsh frog species (the Pelophylax ridibundus complex) are cryptic, we used molecular markers to identify them. Three marsh frog species (P. ridibundus, P. kurtmuelleri and P. cf. bedriagae) inhabit the northern part of Western Palearctic. We created a database of localities and built models of their modern distribution. These models showed that the most suitable habitats are on the north of the Mediterranean region for P. cf. bedriagae, temperate Europe for P. ridibundus, and the Balkan coastal areas for P. kurtmuelleri. The projection of the modern ecological niches under the late-Quaternary climatic conditions showed that the range of P. kurtmuelleri remained largely unchanged during the period, whereas the ranges of P. cf. bedriagae and especially P. ridibundus changed greatly over time. During the Last Glacial Maximum, the presumed range of P. cf. bedriagae covered a relatively large area in the north of the Mediterranean region and the south of European Russia. Glacial refugia of P. ridibundus were apparently located in the northern Balkans, the northern coast of the Black and Azov seas, and possibly in Western Europe. The northward long-distance post-glacial dispersal of P. ridibundus occurred from refugia in the northeastern Balkans and the Black-Azov seas region. Since the Late Pleistocene, suitable habitats for P. cf. bedriagae in southern Russia began to decline, but local habitats for P. ridibundus become more suitable. Therefore, a mosaic of populations consisting of these both species and their hybrids has now been found here

XPS Study of Niobium and Niobium-Nitride Nanofilms

A new, XPS-based approach to quantitative and nondestructive determination of the chemical and phase layer composition of multicomponent multilayer films is proposed. It includes a new method for subtracting the background of repeatedly inelastically scattered photoelectrons, taking into account the inhomogeneity of inelastic scattering over depth; a new way of decomposing a photoelectron line into component peaks, taking into account the physical nature of various decomposition parameters; solution of the problem of subtracting the background and decomposing the photoelectron line simultaneously; and determination of the thickness of the layers of a multilayer target using a simple equation. The phase-layer composition of nanoscale Nb and NbN films is determined, and the thicknesses of these layers are calculated

Протестные настроения в России на фоне Европейских государств: анализ кейсов 2017-2019 годов

The last two years of development of the Russian political system were characterised by the protest mood increasing. Social discontent and various forms of political protest have become a noticeable element of social and political life. It is symptomatic that the protest mood develops during electoral campaigns (that predetermined the victory of the opposition in the elections in a number of regions), and also as a result of development and implementation of the current governmental processes. Considering that elections have been held in the majority of Russian regions during 2017-2019, the attention to the protest movement from various political actors will increase. The authors analyze the forms, main actors and technologies of protests, worked out their typology based on case studies. The current protest mood in Russia is compared with the situation in several EU countries (primarily in France, as well as in Portugal, Poland, Serbia and Greece). In conclusion of the article will be presented the forecasts of the socio-political situation development in the Russian Federation

Layer chemical and phase profiling of niobium nitride thin films on a silicon substrate oxidized on air was performed with the help of a method designed by us. The method includes: a new method of background subtraction of multiple inelastically scattered photoelectrons considering depth inhomogeneity of electron inelastic scattering; a new method of photoelectron line decomposition into component peaks considering physical nature of different decomposition parameters; joint solution of the background subtraction and photoelectron line decomposition problems; control of line decomposition accuracy with the help of a suggested performance criterion; calculation of layer thicknesses for a multilayer target using a simple formula

Air-Oxidation of Nb Nano-Films

X-ray photoelectron spectroscopy (XPS) depth chemical and phase profiling of air-oxidized niobium nanofilms has been performed. It is found that oxide layer thicknesses depend on the initial thickness of the niobium nanofilm. The increase in thickness of the initial Nb nano-layer is due to increase in thickness of an oxidized layer
