Structural and mechanical properties and effective permeability of fissured materials

The article investigates the dependences of porosity and of the permeability tensor of an elastic fissured medium on the characteristics of its state of stress and the pressure of the permeating liquid.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 49, No. 5, pp. 818–826, November, 1985.     

Use of biocompatible calcium-phosphate glass ceramic BGC in surgical treatment of maxillary cysts

The possibility of using the granulated form of biocompatible material made of calcium-phosphate glass ceramic BGC for treatment of maxillary cysts was demonstrated.     

Determination of the melting point of ice in porous glass in relation to the size of the pores

The method of proton magnetic resonance is used to determine the melting point of ice particles in the pores of monodisperse porous glasses ranging from 10 to 1000 Å in radius.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 48, No. 3, pp. 461–466, March, 1985.     

System analysis of the efficiency of turbocompressor units for the gas and oil industry

Schemes are analyzed for turbocompressor installations (TCI) with a gas turbine drive (GTD) for collecting and transporting petroleum gas (PG) and natural gas (NG). The makeup of the equipment for an NG TCI setup based on a GTD of the aircraft or ship type is considered. Energy characteristics of the NG TCI and PG GTD are provided. A procedure for energy analysis of the TCI is developed. __________ Translated from Khimicheskoe i Neftegazovoe Mashinostroenie, No. 8, pp. 44–48, August, 2007. From the editor.
