METHODOLOGY FOR EVALUATING THE STRATEGY AND PROGRESS OF INSTITUTIONAL TRANSFORMATIONS OF INDUSTRIAL COMPLEXES IN THE DIGITAL ECONOMY
The article is devoted to topical issues of transformation and development of Russian industry. The purpose of the research is to develop and test a methodology for evaluating the strategy and progress of institutional transformations of industrial complexes in the digital economy. The article defines the content of the methodology as a sequence of analytical stages that allow us to give a multidimensional and integrated assessment of strategic, process, structural, functional, technological, innovative, digital, institutional and other key aspects of the transformation of industrial complexes. The novelty and distinctive feature of the method are the ability to analyze the efficiency, speed, scale and resource support of institutional transformations of various types of industrial complexes in comparison with the average values of indicators for the Russian industry. Testing of the method was carried out on the production complex of Russia as a whole, as well as four industry, five territorial and fifteen local complexes. It is determined that transformations in the domestic industry are local, reactive and low-dynamic. Reengineering of functions, business processes, organizational structures, institutions and management systems of enterprises is carried out at an insufficient pace. Most Russian companies have not changed their strategies in the context of the digital economy. A list of ways to improve the efficiency of transformation of domestic enterprises is proposed

Three-dimensional media for mobile devices
Cataloged from PDF version of article.This paper aims at providing an overview of the core technologies enabling the delivery of 3-D Media to next-generation mobile devices. To succeed in the design of the corresponding system, a profound knowledge about the human visual system and the visual cues that form the perception of depth, combined with understanding of the user requirements for designing user experience for mobile 3-D media, are required. These aspects are addressed first and related with the critical parts of the generic system within a novel user-centered research framework. Next-generation mobile devices are characterized through their portable 3-D displays, as those are considered critical for enabling a genuine 3-D experience on mobiles. Quality of 3-D content is emphasized as the most important factor for the adoption of the new technology. Quality is characterized through the most typical, 3-D-specific visual artifacts on portable 3-D displays and through subjective tests addressing the acceptance and satisfaction of different 3-D video representation, coding, and transmission methods. An emphasis is put on 3-D video broadcast over digital video broadcasting-handheld (DVB-H) in order to illustrate the importance of the joint source-channel optimization of 3-D video for its efficient compression and robust transmission over error-prone channels. The comparative results obtained identify the best coding and transmission approaches and enlighten the interaction between video quality and depth perception along with the influence of the context of media use. Finally, the paper speculates on the role and place of 3-D multimedia mobile devices in the future internet continuum involving the users in cocreation and refining of rich 3-D media content
Effect of titanium on the primary radiation damage and swelling of vanadium-titanium alloys
In this paper, a molecular dynamic study of the atomic displacement cascade development in pure vanadium and V-Ti alloys with titanium concentrations of 4, 8, and 16% is carried out for energies of a primary knocked-out atom of 5, 10, and 20 keV. The interactions between atoms in the V-Ti system are specified in the framework of a method developed earlier for modeling systems with metallic and covalent types of chemical bon
Molecular dynamics simulation of primary radiation damage in vanadium and alloy V-4Ti
The interatomic interaction in V and alloy V-4Ti was described on the base of modern potentials of interatomic interactions which took into account the interaction of screened ions at small interatomic distances and allowed to simulate correctly radiation damage. The main characteristics of atomic displacement cascades in simulated crystallites were calculated: the number of defects at different stages of cascade development, the size of the radiation-damaged regions, and an analysis of the estimation of the number, types and sizes of the surviving radiation defects in crystallites. The results obtained are compared for vanadium and alloy V-4T
Rational antibacterial therapy for toxic osteonecrosis of the jaws
Background. Toxic osteonecrosis of the jaw is a new disease of the XXI century. It develops due to the use of an artificially manufactured narcotic substance desomorphine.
Aim. To determine the species composition of microflora and to study its sensitivity to antibiotics for toxic osteonecrosis of the jaws, depending on the phase of the inflammatory process to develop the principles of rational antibacterial therapy of this pathology.
Methods. A retrospective study was conducted for 38 patients aged from 21 to 45 years, observed in the PSMU dental clinic from 2012 to 2018, including 25 men and 13 women. They were divided into 2 groups. The first group (19 patients) were admitted for an emergency treatment in the acute phase of the inflammatory process, accompanied by the development of pyo-inflammatory complications in the maxillofacial area. The second group (19 patients) were hospitalized as planned for sequestrectomy. A bacteriological study from the pathological lesion was carried out in all the subjects with the subsequent determination of the sensitivity of the selected microflora to antibiotics.
Results. The analysis of the obtained results revealed the following differences in the composition of the predominant microflora: in the group of patients with osteonecrosis in the acute phase, the prevailing group of bacteria were staphylococci, in the group of patients with osteonecrosis in the chronic phase streptococci. In addition, the presence of such microorganisms as enterococci and acinetobacter was noted in the first group, and bacilli and fungi were noted in the second group. The isolated microorganisms in the first group were also more susceptible to antibiotics than those in the second group. At the same time, the use of levofloxacin and gentamicin is preferable in both study groups. In addition, antibiotics of the penicillin family, cephalosporins and chloramphenicol may be used in the acute phase.
Conclusion. Our study shows that the composition of microflora in toxic osteonecrosis is diverse and depends on the phase of the inflammatory process. The study results form a basis for the prescription of a rational antibacterial therapy, which contributes to a more successful treatment of this disease, reducing the risk of developing severe purulent complications and the inflammatory process generalization
Self-point defect trapping responsible for radiation swelling reduction in V-Ti alloys
The very low swelling of V-Ti alloys under neutron irradiation is a poorly understood phenomenon. To uncover the underlying mechanism of swelling reduction, we performed density functional theory and molecular dynamics simulations with a V-4% Ti random alloy with interatomic potentials. We find that titanium solutes efficiently trap vacancies and self-interstitial atom

Release of Lungworm Larvae from Snails in the Environment: Potential for Alternative Transmission Pathways
Background: Gastropod-borne parasites may cause debilitating clinical conditions in animals and humans following the consumption of infected intermediate or paratenic hosts. However, the ingestion of fresh vegetables contaminated by snail mucus and/or water has also been proposed as a source of the infection for some zoonotic metastrongyloids (e.g., Angiostrongylus cantonensis). In the meantime, the feline lungworms Aelurostrongylus abstrusus and Troglostrongylus brevior are increasingly spreading among cat populations, along with their gastropod intermediate hosts. The aim of this study was to assess the potential of alternative transmission pathways for A. abstrusus and T. brevior L3 via the mucus of infected Helix aspersa snails and the water where gastropods died. In addition, the histological examination of snail specimens provided information on the larval localization and inflammatory reactions in the intermediate host.
Methodology/Principal Findings: Twenty-four specimens of H. aspersa received ~500 L1 of A. abstrusus and T. brevior, and were assigned to six study groups. Snails were subjected to different mechanical and chemical stimuli throughout 20 days in order to elicit the production of mucus. At the end of the study, gastropods were submerged in tap water and the sediment was observed for lungworm larvae for three consecutive days. Finally, snails were artificially digested and recovered larvae were counted and morphologically and molecularly identified. The anatomical localization of A. abstrusus and T. brevior larvae within snail tissues was investigated by histology. L3 were detected in the snail mucus (i.e., 37 A. abstrusus and 19 T. brevior) and in the sediment of submerged specimens (172 A. abstrusus and 39 T. brevior). Following the artificial digestion of H. aspersa snails, a mean number of 127.8 A. abstrusus and 60.3 T. brevior larvae were recovered. The number of snail sections positive for A. abstrusus was higher than those for T. brevior.
Conclusions: Results of this study indicate that A. abstrusus and T. brevior infective L3 are shed in the mucus of H. aspersa or in water where infected gastropods had died submerged. Both elimination pathways may represent alternative route(s) of environmental contamination and source of the infection for these nematodes under field conditions and may significantly affect the epidemiology of feline lungworms. Considering that snails may act as intermediate hosts for other metastrongyloid species, the environmental contamination by mucus-released larvae is discussed in a broader context
