This paper presents power series similarity solutions for spherical shock waves of variable energy propagating in a radiating gas, taking into consideration the Rosseland’s radiative diffusion model. These similarity solutions are obtained for an energy i... see more

The expanding (decaying) universe is discussed in the framework of a local quantum field theory, based on a Lagrangian, in which all fermion operators are coupled to bosons. In this formalism the initial phase of the universe has been explained by creatio... see more

Cas A is the well known supernova remnant and detailed observational data have been accumulated. In particular, recent observations suggest that the element distributions for silicon (Si) and iron (Fe) are very peculiar: Fe locates in front of Si. On the ... see more

In the beginning of 1973 in the USSR the study of possibility of LJE designing was conducted. The reflector, located in the tail of the rocket prototype, concentrated the obtained radiation in air and ensured micro-burst that the reactive thrust was creat... see more
A technique for obtaining of the repetitively pulsed operating regime in high-power wide-aperture lasers is proposed and experimentally realized. In this regime, the laser emits a train of pulses with duration of 100–150 ns and a pulse repetition rate of ... see more
