    Hysteretic Loops, 1,5; 3,0; 4,5; 6 and 10 nm in thickness, obtained by magnetron sputtering of Ni81Fe19 alloy, were measured by means of vibration magnetometer. It has been detected that by increasing the film thickness from 3 to 10 nm coercive force (HC) increases as well. In the direction perpendicular to the axis of easy magnetization the loop form considerably differs from the right-angled one, which is caused by amplitude dispersion of anisotropy. The films, derived in scattered magnetic field of the Earth, are by magnetic parameter isotropic. The results of atomic force microscope investigation indicate to the granular structure of films and confirms the presence of non-magnetized areas among the examined films. The critical thickness at which permalloy films pass from multi-domain to single-domain state was 10 nm. Estimation of the critical thickness of the transition from single-domain state to superparamagnetic led to the values of 1.5-2 nm.

    Background. Neonatal sepsis presents one of the current issues in modern pediatrics. The orthopedic outcomes of such a state and the possibility of treatment, in particular by surgical spinal reconstruction, are rarely analyzed. Objective. To analyze pathology features and treatment outcomes in infants with vertebral complications resulted from neonatal sepsis.Material and Methods. The analysis of observation and treatment of 15 infants, who have undergone neonatal sepsis which led to vertebral lesion with subsequent gross kyphotic deformity formation, is presented.Results. Average age of infants was 2.5 months when spinal pathology was diagnosed. In 7 of the 15 observations, a local angular kyphosis was revealed when the acute phase of disease was already passed (β€žcuredβ€œ). The thoracic vertebrae were most often affected, mainly Th 7-8 vertebral bodies. Average kyphosis was 53Β°. All infants were operated on during the period from 2006 to 2017. Each had two-stage spinal reconstruction including the anterior spinal fusion using a titanium mesh cage filled with bone autografts, or an autogenous bone graft only. At the second stage, the instrumental correction and fixation of the spine with a multi-support laminar structure were performed. Average age of patients at the time of surgery was 14 months. Average value of kyphosis correction was 27Β°. Further correction and anterior spinal fusion were achieved when performing the incorporation of a titanium mesh cage with bone autografts. The histological and bacteriological examination of the surgical material did not reveal any signs of infection or inflammation. Correction of deformity and restoration of the supporting strength of anterior vertebral column as a result of surgery were achieved in all cases. Various complications in the early and late followup period were reported in a total of 7 cases. Repeated interventions were required in two patients: in one case in the early period (dislocation of the structure supporting hook) and in one case in the long-term period (graft resorption and kyphotic deformity relapse).Conclusion. One of the complications of neonatal sepsis is severe multilevel thoracic spondylitis, the outcome of which is the formation of severe kyphosis against the background of subtotal bone vertebral destruction. The principal possibility of radical spine reconstruction in infants with achievement of good anatomical and functional results is shown.Β ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ.

    The most common method for gold content determination in raw materials is fire assay. An alternative to this method is atomic absorption in a solution obtained by dissolving an initial sample in aqua regia. This study focuses on the sludge of one of the chemical plants, in which the barite concentrate (barium in sulphate form) is fused with calcium chloride at coal presence, and then leached in water. Decomposition of samples in aqua regia followed by atomic absorption analysis, as well as fire assay, showed gold content in the sludge at the level of 1-4 gram per ton. The presence of infusible and chemically resistant compounds in the sludge does not allow to the reliable determination of the gold content. Sintering with sodium peroxide for decomposition of stable compounds at 700 ∘ C, dissolution of sinter in acidic solution, evaporation and fire assay of residue made it possible to establish a reliable concentration of gold in the sludge - 10-20 gram per ton. It was found that a direct determination of gold in acidic sinter leach solution provides inadequate values associated with the influence of the background. Keywords: Gold determination, barium sludge, fire assay, atomic absorptio

    The objective of this paper is the construction and analysis of the model of the wireless LTE network (Long Term Evolution) as a multiserver queuing system where losses are caused by a lack of resources required to service requests. Adopted by the service application takes a random amount of resources given to several types of distribution functions. Random vectors describing the requirements of applications to resources, processes do not depend on input flow and service distribution are jointly independent and identically distributed. L independent Poisson flows of requests enter the system, and there are N identical devices. Service times are distributed exponentially. The functioning of the system is described by the semi-Markov process, which takes into account the number of serviced requests, their types and amounts of resources they occupy. Explicit expressions for the stationary distribution of the semi-Markov process, and the theorem on product form solution are main results of the paper. Further studies suggest checking the hypothesis of invariance with respect to the form of the stationary distribution of the distribution of the service time and the development of numerical methods for the analysis of probability measures of the system.Π—Π°Π΄Π°Ρ‡Π΅ΠΉ Π΄Π°Π½Π½ΠΎΠΉ ΡΡ‚Π°Ρ‚ΡŒΠΈ являСтся построСниС ΠΈ Π°Π½Π°Π»ΠΈΠ· ΠΌΠΎΠ΄Π΅Π»ΠΈ соты бСспроводной сСти LTE (Long Term Evolution) Π² Π²ΠΈΠ΄Π΅ ΠΌΠ½ΠΎΠ³ΠΎΠ»ΠΈΠ½Π΅ΠΉΠ½ΠΎΠΉ систСмы массового обслуТивания (БМО) с потСрями, Π²Ρ‹Π·Π²Π°Π½Π½Ρ‹ΠΌΠΈ Π½Π΅Ρ…Π²Π°Ρ‚ΠΊΠΎΠΉ рСсурсов, Π½Π΅ΠΎΠ±Ρ…ΠΎΠ΄ΠΈΠΌΡ‹Ρ… для обслуТивания заявок.

    Aim: to calculate the index of years of life lost population due to premature death in the Tomsk region in 2012, and the contribution of various groups of diseases in the total indicator DALY among males and females. Β Materials and methods: in the calculation of DALY used the number and the gender and age structure of the population of Tomsk region by 01.01.2012, according to Rosstat. To conduct the calculation of DALY used the methodology presented by the world Bank in the report Β«Investing in healthΒ» in 1993 According to the methodology, the DALY is the number of years of life of the population, lived with disability or other health problems, and lost due to premature death. Results: the total loss of DALYs in the Tomsk region by the end of 2012 amounted 112,3, per 1000 population (11,6Β±8,9). In the structure of DALYs by cause of death 1st place is occupied by diseases of the circulatory system, 2nd injury and poisoning, 3rd neoplasms. Conclusions: the indicator DALY in the Tomsk region are significantly lower than the Russian Federation as a whole (according to S.A. Leonov - 1.25 times, according to G. Yang - 2 times). The relatively low level of DALYs in the Tomsk region is associated with favourable compared with other regions of the age structure (younger populations). It should also be noted that more than 70% of population live in urban areas, where, as is known, the availability of medical care are higher than in rural.ЦСль исслСдования: расчСт показатСля потСрянных Π»Π΅Ρ‚ ΠΆΠΈΠ·Π½ΠΈ насСлСния Π² Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Π΅ ΠΏΡ€Π΅ΠΆΠ΄Π΅Π²Ρ€Π΅ΠΌΠ΅Π½Π½ΠΎΠΉ смСрти Π² Вомской ΠΎΠ±Π».

    No full text
    Experimental and theoretical research of the process of low-temperature transformations of mixture ethanol/water in nonequilibrium plasma of the electric discharge in gas channel with fluid wall was carrying out. The gas channel in liquids was created by two counter airstreams in liquids and vapor of the liquids. The gas chromatography and massspectrometric techniques for investigation of stable gas-phase conversion products were used. The power inputs on conversion of mixture in synthesis – gas were measured. The values of efficiency, coefficient of energy transformation, specific energy requirement of system were calculated. Experimental results indicate the possibility and efficiency of plasmachemical conversions of ethanol in syntheses-gas in such plasma-liquid system of the atmospheric pressure.ΠŸΡ€ΠΎΠ²ΠΎΠ΄ΠΈΠ»ΠΎΡΡŒ Π΅ΠΊΡΠΏΠ΅Ρ€ΠΈΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½Π΅ Ρ‚Π° Ρ‚Π΅ΠΎΡ€Π΅Ρ‚ΠΈΡ‡Π½Π΅ дослідТСння процСсів Π½ΠΈΠ·ΡŒΠΊΠΎΡ‚Π΅ΠΌΠΏΠ΅Ρ€Π°Ρ‚ΡƒΡ€Π½ΠΎΠ³ΠΎ пСрСтворСння ΡΡƒΠΌΡ–ΡˆΡ– Π΅Ρ‚Π°Π½ΠΎΠ»/Π²ΠΎΠ΄Π° Π² Π½Π΅Ρ€Ρ–Π²Π½ΠΎΠ²Π°ΠΆΠ½Ρ–ΠΉ ΠΏΠ»Π°Π·ΠΌΡ– Π΅Π»Π΅ΠΊΡ‚Ρ€ΠΈΡ‡Π½ΠΎΠ³ΠΎ розряду Π² Π³Π°Π·ΠΎΠ²ΠΎΠΌΡƒ ΠΊΠ°Π½Π°Π»Ρ– Π· Ρ€Ρ–Π΄ΠΊΠΎΡŽ ΡΡ‚Ρ–Π½ΠΊΠΎΡŽ.

    High Energy Neutrino Signals of Four Neutrino Mixing

    Full text link
    We evaluate the upward shower and muon event rates for two characteristic four neutrino mixing models for extragalactic neutrinos, as well as for the atmospheric neutrinos, with energy thresholds of 1 TeV, 10 TeV and 100 TeV. We show that by comparing the shower to muon event rates, one can distinguish between oscillation and no-oscillation models. By measuring shower and muon event rates for energy thresholds of 10 TeV and 100 TeV, and by considering their ratio, it is possible to use extragalactic neutrino sources to determine the type of four-flavor mixing pattern. We find that one to ten years of data taking with kilometer-size detector has a very good chance of providing valuable information about the physics beyond the Standard Model.Comment: version accepted for publication in Phys.
