In this article, the authors consider the issues of using coal as one of the main sources of thermal energy when hiding criminal corpses by burning. It has been established that it is impossible to reproduce the conditions of a crematorium under domestic conditions, and therefore, in order to destroy a corpse, a criminal needs access to a heat source on an industrial scale. Most often, criminals use boiler and stoker stoves to hide the corpse, or destroy the corpse in storage facilities where coal is stored. In the course of investigating criminal cases about these crimes, investigators must find out how the criminal was able to get access to the source of energy - coal, in cases where the coal does not belong to him on the basis of ownership. Meanwhile, the study of criminal cases showed that the duties under consideration are not fulfilled by investigators properly or are not performed at all. The article touches upon the issues of prosecutor's supervision over the investigation of this category of cases, and measures that the prosecutor could take to activate the investigation bodies and other officials in order to counteract the use of coal in criminal acts.

This paper considers various experimental designs on the Atlas facility to study the physics of liners and determine the optimum conditions of their stable motion. In one of the versions, in comparison with the Liner Demonstration series of experiments, in which unstable liner motion was observed, it is proposed to reduce the initial liner radius without changing its mass, which, according to twodimensional calculations, should to lead to more stable motion of the liner with unchanged velocity. It is also proposed to perform an experiment in which periodic perturbations at a certain wavelength are created on the outer surface of the liner with a simultaneous increase in its thickness. According to calculations, the growth of chaotic perturbations is stabilized in this case with the preservation of the liner velocity.
