Mixing of wakes in a longitudinal magnetic field

The results of measuring the velocity profiles in the initial section of mixing of turbulent wakes of an electrically conducting fluid in a longitudinal magnetic field are presented. It is shown that the magnetic field has a substantial effect on the jet; it narrows the width of the mixing zone and increases the length of the initial section in comparison with the case of the absence of a magnetic field. The results obtained indicate that the velocity profiles in the mixing layer during flow in a longitudinal magnetic field are self-preserving. The function taking into account the effect of the magnetic field in the expression for eddy stresses is determined on the basis of the experimental data. The width of the mixing zone during flow of wakes in the initial section in a longitudinal magnetic field was calculated with the use of the dependence obtained for . The calculation results are compared with experimental data.Moscow. Translated from Izvestiya Akademii Nauk SSSR. Mekhanika Zhidkosti i Gaza, No. 5, pp. 33–44, September–October, 1972.

Selectivity of the membrane action of a cytotoxin from the venom of the Central Asian cobra

It has been shown that the selectivity of the direct hemolytic effect of the cytotoxin on different erythrocytes correlates with its influence on the ionic permeability of the membranes of these erythrocytes. It has been established on bilayer phospholipid membranes that the influence of the cytotoxin on their ionic permeability depends on the amount of cholesterol in them. It is assumed that the resistance of the cells to the cytotoxin is determined by the stability of the phospholipid backbone of their membranes.Institute of Biochemistry of the Academy of Sciences of the Uzbek SSR, Tashkent.
