Mathematical Modeling of Boson-Fermion Stars in the Generalized Scalar-Tensor Theories of Gravity

A model of static boson-fermion star with spherical symmetry based on the scalar-tensor theory of gravity with massive dilaton field is investigated numerically. Since the radius of star is \textit{a priori} an unknown quantity, the corresponding boundary value problem (BVP) is treated as a nonlinear spectral problem with a free internal boundary. The Continuous Analogue of Newton Method (CANM) for solving this problem is applied. Information about basic geometric functions and the functions describing the matter fields, which build the star is obtained. In a physical point of view the main result is that the structure and properties of the star in presence of massive dilaton field depend essentially both of its fermionic and bosonic components.Comment: 16 pages, amstex, 5 figures, changed conten

The clinical trial of fibrinselective thrombolytic agent Fortelyzin® (III phase) showed the comparative efficacy and safety with Actilyse® in patients with acute myocardial infarction and obtained data permitted to recommend it for clinical usage.Проведенное исследование лекарственного препарата Фортелизин®, вводимого болюсно и болюсно-инфузионно у больных с острым инфарктом миокарда с подъемом сегмента ST, показало сравнимую с Актилизе® эффективность и безопасность исследуемого препарата и позволило рекомендовать его для медицинского применения

Formation of Superhard Nanostructured Ti–Hf–N(Fe) Coatings Obtained by Vacuum Arc Deposition in HF discharge

Superhard nanostructured Ti–Hf–N(Fe) coatings are prepared. The formation of local regions of (Ti, Hf)N, FeN, and Hf is detected using μ-PIXE (ion microbeam). It is revealed that the synthesized coatings have a nanohardness of 48 ± 1 GPa and are composed of nanograins with a size of 4.8–10.6 nm, which are enveloped by finer entities of other phases (Ti, Fe)N and FeN. There is a good correlation between the results derived by XRD, TEM, AFM, and SEM and microanalysis, which in turn are complemented by the analysis results obtained using an ion microbeam and PIXE.
