The results of the study suggest that the distribution of 137Cs is determined by the content of hydromica of silty-clay and clay grain-size fractions, while radiocaesium is mainly accumulated by silty fractions. The accumulation of 226Ra by bottom sediments is mainly determined by the pH geochemical barrier at the water-seafloor ...

The Instruciton of Vladimir Monomakh as a confession and self-report: On the problem of interpretation
The genre of the Instruction of Vladimir Monomakh is considered as a "deed" and "confession and selfreport" (M. Bakhtin) and is related to the fact that the way a text is created is determined by non-literary considerations; the internal plot unfolds as a confession. The creation of the Instruction is interpreted as a deed, which determines the way to salvation for a lay prince.

Numerical solving the problem of detecting of ultraweak diffractors in a complex acoustical medium
Some results of numerical simulating of the problem of detecting of ultraweak diffractors in a complex acoustical medium are represented. The term “ultraweak” here means that the diffractors are not determined by standard depth migration. To solve the problem of detecting we use two procedures: Reverse Time Datuming (RTD) and Common Scattering Point (CSP). The first procedure (RTD) extends (synthetic) wave field from the day surface down to some ...

Then proceeding to voxel presentation is being done. Existence of a tetrahe-dron with its points in cloud points and size-limited sides for which the voxel being tested is internal is treated as a criterion of belongment of voxel to a body....
