    The results of mixing angle measurement for Ξ·β€²\eta', Ξ·\eta mesons generated in charge exchange reactions with Ο€βˆ’\pi^{-} and Kβˆ’K^{-} beams are preseneted. When the Ξ·β€²\eta', Ξ·\eta mesons are described in nonstrange(NS)--strange(S) quark basis the Ο€βˆ’\pi^{-} and Kβˆ’K^{-} beams allow to study ∣ηq>|\eta_{q}> and ∣ηs>|\eta_{s}> parts of the meson wave function. The cross section ratio at tβ€²=0t'=0 (GeV/c)2^{2} in the Ο€βˆ’\pi^{-} beam is RΟ€(Ξ·β€²/Ξ·)=0.56Β±0.04R_{\pi}(\eta'/\eta)= 0.56 \pm 0.04, results in mixing angle Ο•P=(36.8Β±1.)o\phi_{P} = (36.8 \pm 1.)^{o} . For Kβˆ’K^{-} beam the ratio is RK(Ξ·β€²/Ξ·)=1.30Β±0.16R_{K}(\eta'/\eta)= 1.30 \pm 0.16. It was found that gluonium content in Ξ·β€²\eta' is sin⁑2ψG=0.15Β±0.06\sin^{2}\psi_{G}= 0.15 \pm 0.06. The experiment was carried out with GAMS-4Ο€\pi Setup.Comment: 6 pages, 4 figures, 1 table, to be submitted in European physical journal C. Minor changes, the Bibliography extende

    The reaction Ο€βˆ’pβ†’Ξ·Ο€on\pi^-p \to \eta\pi^o n has been studied with GAMS-2000 spectrometer in the secondary 38 GeV/c Ο€βˆ’\pi^--beam of the IHEP U-70 accelerator. Partial wave analysis of the reaction has been performed in the Ξ·Ο€o\eta\pi^o mass range up to 1200 MeV. The a0(980)a_0(980)-meson is seen as a sharp peak in S-wave. The tt-dependence of a0(980)a_0(980) production cross section has been studied. Dominant production of the a0(980)a_0(980) at a small transfer momentum tt confirms the hypothesis of Achasov and Shestakov about significant contribution of the ρ2\rho_2 exchange (IGJPC=1+2βˆ’βˆ’I^GJ^{PC}=1^+2^{--}) in the mechanism of a0(980)a_0(980) meson production in tt-channel of the reaction.Comment: 4 pages, 3 figures, talk given at HADRON'9

    A precise measurement of the vector and axial-vector form factors difference FVβˆ’FAF_V-F_A in the K+β†’ΞΌ+Ξ½ΞΌΞ³K^+\rightarrow{\mu^+}{\nu_{\mu}}{\gamma} decay is presented. About 95K events of K+β†’ΞΌ+Ξ½ΞΌΞ³K^+\rightarrow{\mu^+}{\nu_{\mu}}{\gamma} are selected in the OKA experiment. The result is FVβˆ’FA=0.134Β±0.021(stat)Β±0.027(syst)F_V-F_A=0.134\pm0.021(stat)\pm0.027(syst). Both errors are smaller than in the previous FVβˆ’FAF_V-F_A measurements.Comment: 9 pages, 8 figure

    Introduction. Support systems currently used in modern cardiac surgery to provide partial or complete, permanent or temporary replacement of cardiac function are frequently characterized by large dimensions, thus requiring major surgical interventions. Low invasiveness can be ensured by reducing the size of the implanted part of such systems, allowing these devices to be inserted through the femoral artery.Aim. Development of a minimally invasive micropump system to support blood circulation.Materials and methods. Based on the analysis of implementation of micropump circulatory support systems (MCSS), the configuration, operational principles and main components of such a system were determined. When designing a micropump, as a unit defining the weight and size parameters of the entire system, numerical and experimental methods were used to optimize its flow path based on the condition of minimizing blood injury and thrombus formation. The lubrication and cooling system was developed by solving the thermodynamic problem of heat removal. The electronic control unit was developed on the basis of accumulated experience in the design and operation of control units for circulatory support systems.Results. A micropump with a diameter of 6.5 mm and a length of 43 mm with the required hydro- and hemodynamic parameters was designed. The device ensures minimal trauma and thrombus formation. The main MCSS parameters, as well as its main components (electric drives, lubrication and cooling systems), were defined. The configuration and operational principles of the electronic control unit (ECU), consisting in a microprocessor-based control system with feedback, were developed. The ECU built-in software manages the rotational speed of the electric drives of the micropump and coolant supply pump in the required range. In addition, the software is used to measure, display and register the MCSS operational parameters, as well as to monitor their operation in the required ranges and to exchange data between the ECU and the PC.Conclusion. All the necessary documentation for the MCSS nodes and components was prepared. These nodes and components ensure the hydro- and hemodynamic parameters required for the use of the developed minimally invasive micropump system. Future work will address the stages of MCSS assembly and debugging.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    The effect of a new biological preservative representing a mix of lyophilized Lactobacillus plantarum VKPM V-4173, Lactococcus lactis subsp. lactis VKPM V-2092 and Propionibacterium acidipropionici VKPMV-5723 strains (40 : 40 : 20) on the quality of haylage prepared from a mix of vetch, oats, and pea has been studied. The total bacteria content in the preservative was 1Β·1011 CFU/g. Five different variants of conservation of alfalfa haylage prepared at the budding stage were evaluated under laboratory conditions. The variants included a self-conserved control and the preservative at two different dosages (3 and 6 g/ton) with and without the addition of cellulolytic enzymes. The best results were observed in the case of both the enzyme-free and the enzyme-containing preservative at the dosage equal to 6 g/ton. These variants provided the maximum protein content in the haylage (94.3% and 94.5% of the initial content, respectively) and a high content of lactic acid (62.9% and 65.4% of the total acid content, respectively) and also good organoleptic characteristics. The determined optimum biopreservative dosage was tested under industrial conditions using 750 tons of vetch-oats-pea haylage. The use of the biopreservative provided a high-quality haylage of high nutritive value. Industrial evaluation of the effect on the productivity of milk cattle (nΒ =Β 15) of the addition of the biopreservative to the haylage showed that the maximum average daily yield of milk with basic fat content (3.4%) was obtained from cows of the experimental group whose ration included haylage prepared with the use of the studied preservative. This yield came to32.7 kg , which exceeded the yield for the control group (fed on self-conserved haylage) by 7.0%. Three months feeding of cows with the haylage prepared with the use of the new preservative brought a significant saving of money (4,862 rubles per a head at the prices of 2015–2016). ИсслСдовано влияниС Π½ΠΎΠ²ΠΎΠ³ΠΎ биологичСского консСрванта, ΠΏΡ€Π΅Π΄ΡΡ‚Π°Π²Π»ΡΡŽΡ‰Π΅Π³ΠΎ собой смСсь Π»ΠΈΠΎΡ„ΠΈΠ»ΡŒΠ½ΠΎ Π²Ρ‹ΡΡƒΡˆΠ΅Π½Π½Ρ‹Ρ… Π±Π°ΠΊΡ‚Π΅Ρ€ΠΈΠΉ: Lactobacillus plantarum Π’ΠšΠŸΠœ Π’-4173, Lactococcus lactis subsp. lactis Π’ΠšΠŸΠœ Π’-2092 ΠΈ Propionibacterium acidipropionici Π’ΠšΠŸΠœ Π’-5723 (Π² ΡΠΎΠΎΡ‚Π½ΠΎΡˆΠ΅Π½ΠΈΠΈ 40 : 40 : 20) Π½Π° качСство сСнаТа ΠΈΠ· Π²ΠΈΠΊΠΎ-овсяно-Π³ΠΎΡ€ΠΎΡ…ΠΎΠ²ΠΎΠΉ смСси.

    On the Surface Structure of Strange Superheavy Nuclei

    Full text link
    Bound, strange, neutral superheavy nuclei, stable against strong decay, may exist. A model effective field theory calculation of the surface energy and density of such systems is carried out assuming vector meson couplings to conserved currents and scalar couplings fit to data where it exists. The non-linear relativistic mean field equations are solved assuming local baryon sources. The approach is calibrated through a successful calculation of the known nuclear surface tension.Comment: 12 pages, 9 figure

    Searches for the light invisible axion-like particle in K+β†’Ο€+Ο€0aK^{+}\to\pi^{+}\pi^{0}a decay

    Full text link
    A high statistics data sample of the K+K^{+} decays is recorded by the OKA collaboration. A missing mass analysis is performed to search for a light invisible pseudoscalar axion-like particle (ALP) aa in the decay K+β†’Ο€+Ο€0aK^{+} \to \pi^{+} \pi^{0} a. No signal is observed, the upper limits for the branching ratio of the decay are calculated. The 90%90\% confidence level upper limit is changing from 2.5β‹…10βˆ’62.5\cdot10^{-6} to 2β‹…10βˆ’72\cdot10^{-7} for the ALP mass from 0 to 200 MeV/c2c^{2}, except for the region of Ο€0\pi^{0} mass, where the upper limit is 4.4β‹…10βˆ’64.4\cdot10^{-6}.Comment: 6 pages, 6 figure
