    Influence of nanomaterials (based on bentonitic clays and calcium carbonate) in pelagic sediments of the Black Sea on their biologic activity has been investigated. It was shown that chemical composition, preliminary thermal treatment and concentration of nanomaterials in composition with pelagic sediments have a great influence to their medical properties. Based on obtained data for complex influence of nanocomposites to organism (behaviour, nervimuscular irritability, reflexes, vegetative effects, functional condition of lever and kidneys) a conclusion of substantially increasing the biological activity of pelagic sediments with the properties of medicinal mud (peloid), under the influence of bentonite and calcium carbonate that contain nanoparticles. A method for testing the pelagic sea and ocean sediments with nanodispersed components to predict the prospects of their use as medicinal muds (peloids) has been suggested.

    Vanishing Viscous Limits for 3D Navier-Stokes Equations with A Navier-Slip Boundary Condition

    Full text link
    In this paper, we investigate the vanishing viscosity limit for solutions to the Navier-Stokes equations with a Navier slip boundary condition on general compact and smooth domains in R3\mathbf{R}^3. We first obtain the higher order regularity estimates for the solutions to Prandtl's equation boundary layers. Furthermore, we prove that the strong solution to Navier-Stokes equations converges to the Eulerian one in C([0,T];H1(Ω))C([0,T];H^1(\Omega)) and L^\infty((0,T)\times\o), where TT is independent of the viscosity, provided that initial velocity is regular enough. Furthermore, rates of convergence are obtained also.Comment: 45page

    The paper describes the results of the work on improvement of electron linac LUE-40. This linac has been designed for nuclear physics research in the electron energy range 40…100 MeV. The main purpose is to reduce the energy spread, emittance and long-term instability of the beam characteristics. For this purpose the system of klystron high voltage stabilization and the beam loading compensation system have been developed. The improved injector has been put into operation. A new DC power supply system of the magnetic spectrometer has been installed and tested.Приведено описание результатов работы по усовершенствованию линейного ускорителя ЛУЭ-40, предназначенного для проведения ядерно-физических исследований в диапазоне энергий электронов 40…100 МэВ.
