A relationship between the propaEation of seismic waves and the appearance of
an electromagnetic perturbation, the so-called soismoelectric effect is held possible.
The effect originates in slow undulations of the lverrovtrial core which Mly propagato
as an elastic wave. The noticed coincidences of s&lsinic waves ancl electric perturba-
tions indicate the necessity of recording, the slow motions of the terre:Ar*181 core.

Title : Magnetization of a cylinder with winding taking account of magnetic
viscosity
Periodical : Zhur. tekh. fiz., 25, No 13 (November), 1955, 2319-2328
Abstract : The authors consider the following problem: a conducting cylinder of
infinite length parallel to the z-axis is situated in a constant
magnetic field such that at moment tsO within the cylinder there is
established a constant magnetic field of strength Ho directed along
the z-axis; at moment twO the external field is abruptly changed from
H*Ho to HuHl, which can be greater or less than Ho, with the possibility
HjuO. They note that the solution on the basis of the Maxwell equations
was first obtained by B. A. Vvedenskiy (zhRFKbO, 55, 1, 1923; see also
A. N. Tikhonov, Sbornik statey pod red. V. K. Arkad'yeva, Publishing
House of Dept. Tech. Sci. of Acad. Sci. USSR, p. 80, 1938). The aim
of the authors in the present article is to solve the problem of magnetic
reversal of a conducting cylinder in the presence of not only elastic but
also viscous magnetization, a similar problem for the case of plane layer
having been considered by A. N. Tikhonov, ZhTF, 7, 38, 1937. The authors
acknowledge that the works of R. V. Telesnin (ZhETF, 18, No 11, 970,
1948; DPN SSSR, 25, No 5, 1950) suggested the present problem.

This collection originates in a textbook of Samarskij and Tichonov (The
equations of mathematical physics, Moscow 1953) and a smaller collection of
problems of Budak (collection of problems for mathematical physics, Mau-101I
(1952)). But thin material is still extended, especially it in represented in
a detailed manner. 130 pages contain problems and questions and ~$O pages
contain solutions and instructions for solutions. Only boundary value problems
for partial differential equation3 of second order are treated. The knowledge
of the general theory is assumed. In three chapters the three types of
equations are treated, the chapters are subdivided according to methods to
be applied. There follow again three chapters with the same busdivision which
treat essentially more difficult questions. An important part of the problem
consists in deriving the differential equation and its boundary conditions
from the given physical problem. The method of solution is given so detailed
that a self-study for students is possible. The book represents a sourcearc'.
