Effect of the Interface on the Compressibility of Substances with Spherical Nano-Inhomogeneities on the Example of Al/C.

The paper examines the compressibility of media with nano-inhomogeneities using the example of an aluminum melt and C fullerenes immersed in it. The results of molecular dynamics simulations indicate a significant effect of the interface on the effective compressibility of a heterogeneous medium. It is found that the application of the rule of mixture for the Al/C system results in an incorrect qualitative picture of the dependence of compressibility on the concentration of fullerenes.

[The effect of low frequency electrical stimulation on bone tissue regeneration].

The study was performed on 30 male rats of Wistar line (weight 330-360 g, age 3.5 months).In an experimental model of damage to the femur bone in the hip joint studied the effect of low frequency electrical stimulation of the damaged area on the rate of regeneration of bone.

[Evaluation of the immunogenic and reactogenic properties of vaccine "Euvax B" in persons aged 16-18 years in different geographical zones of Russia].

The comparative evaluation of the reactogenic and immunogenic properties of vaccine "Euvax B" in adolescents aged 16-18 years was carried out in factory housing estate Lvovsky, the Podolsk district, the Moscow region, and in the Yamalo-Nenets Autonomous District (AD): in towns Salekhard, Noyabrsk, Muravlenko, in housing estate Tarko-Sale. The evaluation demonstrated that the use of this vaccine in a dose of 20 mg/ml produced no postvaccinal complications and the frequency of postvaccinal reactions was insignificant. Postvaccinal anti-HBs were detected, on the average, in protective concentrations in 98.
