The Method of Manufacturing Nonmetallic Test-Blocks on Different Sensitivity Classes
Nowadays in our modern world there is a vital question of quality control of details made from nonmetallic materials due to their wide spreading. Nondestructive penetrant testing is effective, and in some cases it is the only possible method of accidents prevention at high-risk sites. A brief review of check sample necessary for quality evaluation of penetrant materials is considered. There was offered a way of making agents for quality of penetrant materials testing according to different liquid penetrant testing sensibility classes

The Three Dimensional Thermal Hydraulic Code Bagira.
BAGIRA - a thermal-hydraulic program complex was primarily developed for using it in nuclear power plant simulator models, but is also used as a best-estimate analytical tool for modeling two-phase mixture flows. The code models allow consideration of phase transients and the treatment of the hydrodynamic behavior of boiling and pressurized water reactor circuits. It provides the capability to explicitly model three-dimensional flow regimes in various regions of the primary and secondary circuits such as, the mixing regions, circular downcomer, pressurizer, reactor core, main primary loops, the steam generators, the separator-reheaters. In addition, it is coupled to a severe-accident module allowing the analysis of core degradation and fuel damage behavior. Section II will present the theoretical basis for development and selected results are presented in Section III. The primary use for the code complex is to realistically model reactor core behavior in power plant simulators providing enhanced training tools for plant operators
Stabilization of the floating sternocostal segment of the chest with multiple bilateral fractures of the ribs and the manubrium of the sternum
Among patients with floating rib fractures without pneumo- and hemopneumothorax or after their elimination, the most severe disorders of ventilation and circulation occur in patients with multiple bilateral rib fractures and a fracture of the sternum manubrium with the formation of a floating sternocostal segment of the chest. At the same time, the suction aero- and hemodynamic function of the chest is disturbed, there is pressure on the heart and large vessels. As a result, the efficiency of external respiration progressively decreases, the respiratory muscles are exhausted, which requires an urgent transfer to artificial ventilation of the lungs. The article presents a clinical case of successful treatment of such a chest injury using the authorβs technique (Patent No. 2621871 of the Russian Federation). The extrathoracic silicone reinforced splint has two horizontal branches that go around the mammary glands. The splint is attached to the floating sternocostal segment with ligatures passed behind the sternum and laterally β to stable sections of the ribs along the posterior axillary line on both sides. The tire reliably holds the sternocostal segment from paradoxical movements. The tire is removed after 3Β weeks. By this time, fibrous calluses are formed in places of fractures of bones and cartilage, and the swelling of the chest wall subsides. Superficial bedsores in the places of fixation of the splint are epithelialized under the scab within 7β8 days. The patient was examined a year later, her condition was satisfactory, she had no complaints, there was no chest deformity. The technique is less traumatic, it is indicated for patients with polytrauma and in other cases

Opportunities for bioenergy in the Baltic Sea Region
Security of energy supply, promotion of the bio-economy, nutrient recycling, and innovation are prioritized policy areas in the EU Strategy for the Baltic Sea Region (EUBSR). The Baltic Sea Region (BSR) has a great bioenergy potential worth exploring in this context. This paper explores the state-of-art of bioenergy systems and synergies with eco-systems services in the BSR region in the context of developing the regionβs bio-economy. In this brief assessment, we consider 8 countries (i.e. Sweden, Finland, Estonia, Latvia, Lithuania, Poland, Denmark, and Belarus) in the region. While the production and use of modern bioenergy can help reduce greenhouse gas (GHG) emissions, promote energy security, diversify energy resources, and contribute to a successful circular economy and rural development, it is important to find a balance between the exploration of resources and the management of eco-systems services. In addition, both climate change vulnerability and bioenergy production may affect the environment and the capacity of the BSR to deliver ecosystem services (ESS). We recommend integrated strategies for optimal use of bioresources in the region. Bioeconomy can be realized by innovative approaches, establishing cross-cutting institutional and policy linkages for increased prosperity and green growth in the Baltic Sea Region
Digital receivers for low-frequency radio telescopes UTR-2, URAN, GURT
This paper describes digital radio astronomical receivers used for decameter
and meter wavelength observations. This paper describes digital radio
astronomical receivers used for decameter and meter wavelength observations.
Since 1998, digital receivers performing on-the-fly dynamic spectrum
calculations or waveform data recording without data loss have been used at the
UTR-2 radio telescope, the URAN VLBI system, and the GURT new generation radio
telescope. Here we detail these receivers developed for operation in the strong
interference environment that prevails in the decameter wavelength range. Data
collected with these receivers allowed us to discover numerous radio
astronomical objects and phenomena at low frequencies, a summary of which is
also presented.Comment: 24 pages, 15 figure
Examining immune arms in mice immunized with site-specific influenza virus mutants
Site-specific mutants as candidates for live influenza vaccines were resulted from directly introducing into the genome of the pathogenic influenza virus A/WSN/33 (H1N1) strain ts mutations derived from the genes encoding the polymerase complex proteins from some cold-adapted strains serving as attenuation donor. Here we present the data of a comparative study examining immune system arms in mice immunized intranasally with influenza virus mutants and classical cold-adapted reassortant obtained by crossing cold-adapted strain Donor A/Krasnodar/101/35/59 (H2N2) with strain A/WSN/33 (H1N1) bearing surface antigens (hemagglutinin and neuraminidase) similar to mutants. Immunophenotyping mononuclear leukocytes from immunized mice indicated at moderate suppressive effect after using site-specific mutant and the HA reassortant viruses on some immune cell subsets. All viruses in immunized mice resulted in activation of certain lymphocyte subsets including MHC II-positive cells, CD45+/CD19+ B lymphocytes and natural killer cells (CD16/32+/CD3β). Timescale and magnitude of activation markedly differed for each cell subsets. Mice immunized with mutants M26 and U2 peaked with count of CD16/32+/CD3β expressing cells on day 2 after the second immunization compared with control (p < 0.05) that may suggest about an important role for NK cells in activating immune response. In contrast, no significant changes were observed during the study in percentage of CD4+/CD25+/Fox P3 regulatory T cells, CD4+ T helpers and CD8+ cytotoxic cells, except for a sharply decreased count of activated CD4+/CD25+ cells (4-fold) on day 7 after immunization with mutant virus M26. Moreover, mutants U2 and M26 more moderately increased percentage of TLR2- and TLR4-positive cells. The viruses studied ambiguously affected count of TLR9-expressing cells in immunized animals. All viruses increased phagocytic activity in monocytes, but not neutrophils. Despite the moderate activation of innate and adaptive immunity arms, site-specific mutants more profoundly affected humoral reactions inducing increased antibody titers, so that immunogenicity of mutant viruses was higher than that of the cold-adapted reassortant. Thus, the findings hold a promise of using site-specific mutants as live influenza vaccines
