    The ability to extract the pulse width and translate it into the actual disk width of the Extensive Air Showers (EAS) is a hard one requiring accurate knowledge of the system performance. For that, the analysis for the cable calibration for Horizon-10T detectors has been re-analyzed in a different form that allows for better signal width measurements. An innovative detector system Horizon-10T, constructed to study EAS in the energy range above 1016 eV coming from a wide range of zenith angles (0o - 85o), is located at Tien Shan high-altitude Science Station of Lebedev Physical Institute of the Russian Academy of Sciences at approximately 3340 meters above the sea level.Comment: in-depth analysis of cable calibration for 'new' cables only v2 corrects minor typo

    Giant popliteal artery aneurysm

    Introduction: Popliteal artery aneurysm is a pathology that appears regularly in daily practice of a vascular surgeon since the popliteal artery is the most common location of aneurysms (about 70%). A rare form of aneurysm of the popliteal artery is a giant aneurysm, the diameter of which is more than 7–8 cm. Giant aneurysms are of a great clinical importance due to the high risk of rupture and complications, and the fact that this pathology has its own peculiarities of surgical treatment.Material and methods: We conducted an electronic bibliographic search Pubmed, Cochrane Library, Wiley to find reports about treatment of giant popliteal aneurysms. According to its results the main features of the clinical picture, diagnosis and treatment of giant popliteal aneurysms have been identified.Results and discussion: Surgical treatment of giant popliteal artery aneurysms differs from the treatment of regular popliteal artery aneurysms and is associated with the choice of adequate access and the need for partial or full resection of the aneurysm. Endovascular treatment methods are used much less frequently, however, with the improvement of techniques and the emergence of new technologies, an increase in number of giant aneurysms successful treatment cases is expected

    Study of the Effect of Y2 O3 Doping on the Resistance to Radiation Damage of CeO2 Microparticles under Irradiation with Heavy Xe22+ Ions

    This paper presents the results of a study on the influence of Y2 O3 doping on the resistance to radiation damage and an assessment of structural changes associated with the accumulation of radiation defects in CeO2 microparticles under irradiation with heavy Xe22+ ions. The relevance of this study consists of the prospects for the use of CeO2 microparticles as materials and candidates of inert matrices of nuclear fuel. A method of solid-phase synthesis was applied to obtain microparticles with different concentrations of dopant. It included grinding of CeO2 and Y2 O3 microparticles followed by thermal sintering at 1100◦ C in an oxygen-containing medium to produce highly ordered microparticles. During the study of the structural characteristics of the synthesized microparticles, it was found that increasing the dopant concentration from 0.05 mol.% to 0.15 mol.% leads to an increase in the crystallinity degree as well as a decrease in dislocation density. According to the results of the assessment of the resistance of microparticles to radiation damage, it was found that an increase in the dopant concentration leads to a decrease in swelling and structural distortion by more than 2.5–3 times, which indicates an increase in the radiation resistance. © 2021 by the authors.

    Electromagnetic properties of LaCa[3]Fe[5]O[12] in the microwave range

    Get PDF
    The X-ray diffraction analysis of the LaCa[3]Fe[5]O[12] ferrite (lanthanum ferrite) prepared through high-temperature synthesis via ceramic technology was performed. It was found that ferrites belong to tetragonal system. The electromagnetic response from a flat layer of the composite based on this material under electromagnetic radiation in the frequency range of 0.01-18 GHz was investigated. It is shown that the developed material effectively interacts with electromagnetic radiation. The interaction effectiveness is directly proportional to ferrite concentration. Increased concentration of ferrite leads to growth of the reflection coefficient due to high conductivity of the material and visible decrease in the transmission coefficient in the frequency range of 4-14 GHz

    Ethical and scientific aspects of human embryonic material research: The Great Britain regulations

    Get PDF
    We analyze the ethical and scientific issues of human embryonic specimen and its utilization for research purposes. Human embryonic specimens are the source of stem cells which are the foundation for all organs and tissue formation. The analysis of human embryonic specimens promises to obtain the essential knowledge about human development and reveal the causes of human development pathology. Ethical and scientific problems of human embryonic specimens donation and research are debated here. We review the impact that human embryonic specimens impose on scientific research, usage restrictions, risk assessment, research personnel and donor protection in view of the British, and other European publications, case reports, legislation, regulations and guidelines. This work is focused on the discussion of different aspects of donation and usage of human embryonic specimens obtained after the elective medical termination of pregnancy. We discuss suggestions for improvement of the ethical and scientific regulations for the work with human embryonic donor material in Russian Federation

    A review of simulation and modeling approaches in microbiology

    Get PDF
    Bacterial communities are tightly interconnected systems consisting of numerous species making it challenging to analyze their structure and relations. There are several experimental techniques providing heterogeneous data concerning various aspects of this object. A recent avalanche of metagenomic data challenges not only biostatisticians but also biomodelers, since these data are essential to improve the modeling quality while simulation methods are useful to understand the evolution of microbial communities and their function in the ecosystem. An outlook on the existing modeling and simulation approaches based on different types of experimental data in the field of microbial ecology and environmental microbiology is presented. A number of approaches focusing on a description of such microbial community aspects as its trophic structure, metabolic and population dynamics, genetic diversity as well as spatial heterogeneity and expansion dynamics is considered. We also propose a classification of the existing software designed for simulation of microbial communities. It is shown that although the trend for using multiscale/hybrid models prevails, the integration between models concerning different levels of biological organization of communities still remains a problem to be solved. The multiaspect nature of integration approaches used to model microbial communities is based on the need to take into account heterogeneous data obtained from various sources by applying high-throughput genome investigation methods

    Determination of fluoroquinolone antibiotics through the fluorescent response of Eu(III) based nanoparticles fabricated by layer-by-layer technique

    The present work introduces the determination of fluoroquinolone antibiotics (FQs) in aqueous solutions through the fluorescent response of Eu(TTA)3 and [Eu(TTA)31] (TTA- and 1 are thenoyltrifluoroacetonate and phosphine oxide derivative) complexes encapsulated into the polyelectrolyte capsules fabricated through layer-by-layer deposition of poly(sodium 4-styrenesulfonate) (PSS) and polyethyleneimine (PEI). The variation of luminescent core, polyelectrolyte deposition and concentration conditions reveals two modes of fluorescent response on FQs of diverse structure namely the sensitization and quenching of Eu(III) centered luminescence. The obtained regularities reveal the ternary complex formation and the ligand exchange occurring at the interface of polyelectrolyte coated [Eu(TTA)31] based colloids as the reasons of the diverse fluorescent response of Eu(III) centered luminescence on FQs. The factors affecting the fluorescent response have been revealed, which are: the content of luminescent core, the mode of polyelectrolyte deposition, concentration and structure of FQs. The discrimination of moxifloxacin and lomefloxacin from levofloxacin, ofloxacin, difloxacin, perfloxacin through the quenching of Eu(III) luminescence in PSS-[Eu(TTA)31] colloids has been revealed. © 2013 Elsevier B.V
