Soviet space research: Signs of strain

Soviet Program for Medical Research **†

At the 20th Congress of the Communist party of the Soviet Union, held in Moscow in February, 1956, the sixth five-year plan was presented and accepted. Such plans extend into all walks of life in the U.S.S.R. but particularly in fields of applied science, not the least of which has been the program for work in the medical sciences. This pattern is characteristic of the Soviet Union, and one can...

Soviet Space Stations: Achievements, Trends, and Outlook

It is a widely held belief that the Soviet space program deliberately follows the paths described in the early years of the century by Konstantin Tsiolkovsky. 1 Be that as it may, it is certainly possible to find close parallels between Tsiolkovsky’s writing and the course of events, but more likely these parallels result because modern engineers have arrived at similar solutions to the same pr...

Plane Strain Deformation of a Poroelastic Half-Space Lying Over Another Poroelastic Half-Space

The plane strain deformation of an isotropic, homogeneous, poroelastic medium caused by an inclined line-load is studied using the Biot linearized theory for fluid saturated porous materials. The analytical expressions for the displacements and stresses in the medium are obtained by applying suitable boundary conditions. The solutions are obtained analytically for the limiting case of undrained...

Regeneration research in the Soviet Union.

Over the past 20 years Soviet research in regeneration has undergone a shift in emphasis from work on amphibians to mammals. In that period several distinct schools of thought have arisen, and often there has been considerable controversy as to the nature of certain regenerative processes. At present most mammalian tissues and organs are being studied with respect to natural regenerative capaci...
