    Abstract The longitudinal and transverse magnetostriction λ of the spin-Peierls compound CuGeO3 in the b-c plane is measured in magnetic fields up to 20 T both above and below the transition temperature T sp=14.3K. It is found that for a given crystallographic direction the value of magnetostriction is weakly dependent on the magnetic field direction. In the uniform U phase at T⩾T sp, λ is negative and approximately equal in the b and c directions, while in the dimerized D phase at T〈T sp, λ is positive and λ b 〉λ c . At low temperatures, λ increases sharply at the magnetic-field-induced transition from the dimerized to the magnetic M phase. The experimental data allow estimation of the stress derivatives of the antiferromagnetic intrachain exchange interaction parameter and of the stress dependence of the critical field of the D-Mphase transition.

    Notes:
    Summary A study has been made of the choline acetylase and esterase activities of brains of rats under ether anesthesia, in hypothermia, and during emergence from hypothermia. Ether anesthesia was associated with a considerable rise in choline acetylase, and a smaller rise in choline esterase, activity. Generalized hypothermia of ether-anesthetized rats was invariably associated with fall in choline acetylase activity, as well as, in most cases, in choline esterase activity. During recovery from the hypothermic state rises in the activity of both enzymes were noted. The parallelism of the changes in the activities of the two enzymes suggests that they may have an adaptive-compensatory nature. Disturbances in the correlation of the two activities may lead to changes in acetylcholine metabolism.

    Abstract The paper investigates a closed queue model with controllable priorities in which the customers require a random number of channels simultaneously. A technique for aggregation of phase space states is proposed, reducing the dimension of the problem. Numerical examples are presented.
