... RIZNICHENKO and T. Yu, PLYUSNINA Biology Faculty of the Lomonosov State University (Received 29 September 1994) The model of transmembrane ion transfer is employed to demonstrate the possibility, in principle, of a non-linearly organized biological system to respond to weak low-frequency electromagnetic radiations (10 Vim, 0.1-100 Hz). The interaction of the biological system of ion transfer with an external electromagnetic field leads to bifurcational changes in the system. ...
... E-mail: swan@mch.chem.msu.su (Received 0 XXXXXXX 0000; accepted 0 XXXXXXX 0000) The local environment of the Pb atom in Pbx Sn1 x S solid solution was studied by EXAFS technique. The shortest PbS bond length ° in orthorhombic samples was found to be by 0.2 A shorter than in cubic PbS. ... Strong correlations found in the distribution of metal atoms in the second shell show that the orthorhombic samples can be considered as solid solutions with unexpectedly strong short-range order. ...
