Transport of heat or mass in a dispersed flow

A rigorous derivation of the equations of heat transport is carried out by averaging over an ensemble for a system consisting of a continuous medium with particles imbedded in it, and the closure problem for these equations is discussed.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 30, No. 6, pp. 979–985 June, 1976.     

Increasing the Durability of the Lining of 385-Ton Steel-Teeming Ladles

Data on the durability of the lining of steel ladles in service at an MISW ISC oxygen-converter shop are reported. The best stability of the lining under severe operating conditions was achieved using periclase-carbon refractories (since 2000, available from an in-home manufacturer at the MISW). The highest lining durability is found in periclase-carbon components composed of fused periclase (with MgO content not less than 96%) and coarse-grained graphite (7 – 10%).     

Features of the course and treatment of several eye diseases in Eastern Africa

Examining the specific activity has showed that recombinant vaccinia virus growth factor binds to appropriate receptors on the A-431 cell surface and prompts the healing acceleration of degree III burns in rats. This recombinant factor did not demonstrate pyrogenicity or toxicogenicity in tests on rabbits, guinea-pits, noninbred albino mice.
