problem in the displacements for vibrations of an elastic
medium. SoobMeniya Akad. Nauk Gruzin. SSR. 9, 99-
106 (1948). (Russian)
The boundary value problem consists in the determina-
tion of the displacement vector ia(ul, us, us) which takes
prescribed boundary values JU1, f2, fs) on the boundary S
of an open set B in (xi, x2, x:)-space, satisfies the system of
equations

in A and the radiation condition at infinity if B is un.
bounded. The uniqueness theorem in the plane case has been
discussed earlier [Kupradze, C. R. (Doklady) Acad. Sci.
URSS (N.S.) 6 (193511), 100-104; and in the space case in
a Tiflis dissertation by A. S. Bakalyaev]. In the present
paper the author is r:oncerned with the existence of a solu-
tion. A "fundamen:al vibration tensor solution" of (*) is
introduced, and "double layer potentials" with respect to
this tensor are then constructed. Using the jump conditions
on the boundary for such double layer potentials, the solu-
tion of the (Dirichiet-type) boundary-value problem is
sought in the form of a double layer potential, and an
equivalent Fredholm integral equation for the unknown
density of the double-layer potential is obtained. For the
exterior boundary-value problem the solution exists for any
values of the vibration parameter. J. B. Dias.

The present paper is an extension of a previous one [same
SoobMeniya 9, 99-106 (1948); these Rev. 14, 336]. and
contains an essential simplification of the integral equations

is the frequency of vibration, which was introduced in the

"Iferage: The book is a monograph which presents systematically the
results of research made by the authoralone in the theory of boundary
problems of the equation of vibrations and in the applications of in-
tegral equations to this theory. It offers proofs of uniqueness
theorems of Sommerfeld's simplest problem, which the author says is
based on physical deliberations without rigid application of the
theorem of uniqueness, as well as other much more complicated problems
in the electromagnetic field theory and in the theory of elasticity.

The method of Integral equations is used and new examples of its ap-
plicalGion given. The author's purpose, he states, was to solve
boundary problems of the theory of elasticity for the so-called
established vibrations which are of theoretical interest and have
an application in the theory of foundations and engine construction.
"Phe study of vibrations or equilibrium of non-homogeneous masses
nrid media met in boundary problems Is based in the text on the method
of the potential theory of masses. This method is used in the prob-
lems of propagation of electromagnetic waves, problems of electro-
static3, diffraction of sound, diffraction of a linear polarized
elastic transverse wave and others. The author demonstrates the
riethod of an effective solution of certain systems of singular inte-
gral equations met in applications. Throughout the text the author
refers to Green's functions, the problems and methods of Fredholm,
Dirichlet, Lyapunov, Neumann, Cauchy, and others, the authors of the
Complete theory of the first boundary problem in a statics case,
Weyl',13 dlocuo,,31on (1915) of the aecond boundary problem and to

Preface: None
Introduction: See the "Coverage
Abstract: In the first sections (pp. 14-24) the author discusses fun-
damental results obtained In the theory of vibrations in three di-
mension space by basing his presentation on the principal statements
of the harmonic potential theory, as given by L. Lichtenstein in his
Neuere Entwioklung der Ootentialtheorie.
In the discussion or the equation of vibrations in spherical coordi-
nates, the author introduces the functions of Legendre and Green's
f ormula.
He shows a method of modifying Fredholm's resolvent of the equations
(Da) and (N.) to solve the problem of Dirichlet and Neumann in excep-
tional cases by formulating two theorems which can be applied in the
study of more general cases (PP. 54-62).
In presenting problems connected with the integration of the system
of Maxwell's differential equations, the author shows that the theo-
rem of uniqueness remains applicable In the electromagnetic field

Fredholm's equatJon, met in the solution of the problem of Dirichlet
for a harmonic potential, in several simple cases is solved in uad-
rature*, such as electrostatic field in dielectric medium ( p. 6-
a p
,,5) with spherical and ellipsoidal boundary surfaces.
In Chapter IV the author discusses only strictly periodic vibrations
of an elpstic body, which he calls steady vibrations, introduces the
vector and tensor analyses, the matrix theory and operational methods
in constructing formulae analogous to those of Poisson, Lauricella,
Green and Weyl. He uses the tensor TO MO(PQ) of Bourrinesq-leteyl to
prove the break of continuity in the P T- operation of the potential
of an antenna layer.
Introducing the constants of Lame', the equality of coefficients of
Poisson and using the Cauchy theorm (the generalization of wh1ch he
contests), the author proves the problem of equilibrium of a non-
homogeneous layer under given external forces (pp. 203-204).

In the second method of polution of the first boundary problem of vi-
brationa of an elastic body (pp. 204-209), the author reduces the
problem to the regular equations of Fredholm. Lichtenstein was not
able to establish that Todone's method (1902) on statia*dcal equili-
brium (not given in the text) could be used under certain circum-
stances for solving these problems. However, the author proposes
certain supplements to this method which, he says, expand it to an-
swer also the solution of the first boundary problem of the vibration
of an arbitrary isotropic elastic body. In his discussion he uses
Green's functions, vector analysis, and integral equations.
In Chapte V the author refers to the works of Fredholm Hoelder,
Carleman e ' A
1922), Muskhelishvili (1946) and Mikhlin (194 the th ory&y
of a complex variable (Riemann, Hilbert), singular integral equations
(Poincar~, Bertrand, Tricomi), theory of functions (Noether), and the
expansion of functions using Laurent's series, etc.
Evaluation: The book belongs to pure mathematics. No practical appli-
cations are given, and the examples introduced are entirely theoreti-
cal. A large number of authors and their works, methods and state-
ments are mentioned in the text and footnotes, as may be deduced from

the above coverage and abstract. No special bibliography is attached,
and it Is difficult to define where the author presents his personal
work. It seems that the book is based mainly on the works o~ Sommer-
fold and Fredholm. In some cases, it seems also that the presence of
additional definitions and a more detailed mathematical outlay would
clarify the working out of problems, especially when the author In-
troduces hin own terminology.
Purpose: To give a monographic review of the author's thinking and
conclusions.

TEXT: The problem is stated on the steady oscillations of
two elastic media, one of which fills a three-dimensional outer
region B while the other fills -the inner region Bi Re-

one of the regions B a9 Bi the oscillator is present of fre-
quency W , producing oscillations of the same frccluency in the
composite medium. The author considers four particular cases,
Problem I; Regions B a and B i together fill the whole space.
Problems II a' IIbI IIc: The outer region B a has a finite
boundary S a on which are given either (a) displacements or
(b) stresses or (c) some displacement and some stresses, The
case when S a is plane is not excluded. Problem I is considered
in detail. It is shown that the method is applicable to problem
II, in which case a preliminary construction of Green1c tensor
for the region B a is necessary, and to the case of few or
multi-layer inclusions. The problem is reduced to solving some
system of weighted singular integral equations, It is stated
that the solution can be given as a uniformly converCent series

entire theory is based on the theory of singular integral equations,
making it possible, on the one hand, to investigate a broader group
of boundary problems and, on the other, to uncover new applications
of the method. Another feature of the book is that it treats for
the first time two new methods of solving boundary-problems. The
book is based on lectures delivered by the author in 1959-1962 at
the Iviechanics-Mathematics Department of the Thilisskiy universitet
(19bilisi University) and on various seminar lectures. The author
thanks L. G. Magnaradze and S. G. Mikhlin, who read the manuscript
and made many valuable remarks. Individual chapters of the book were
read also by participants in the seminar, especially M. 0. Basheley-
shvili, T. V. Burchuladze, and T. 0. Gegeliya. The calculations in
the tables of Ch. X were made by N. Arveladze and L. Kbachapuridze
of the Computation Center of AN GruzSSR, for which the author is
sincerely grateful.

where n > 1, and the function a(t) is non-negative and summaole over every finite Interval.
Previous work has centered on finding necessary and sufficient conditions that the solution:
to the above equation be either oscillating or non-oscillating. Also previously derived
have been estimates of the oscillation of the solution for largo values of the argument.
The present paper derives various asymptotic formulas for the oscillation. A t

ABSTRACT: A sketch is given of results obtained by extending Fredholm's method to sys-
tems of singular integral equations in the solution of boundary value problems arising
in the application of potential theory to the theory of elasticity. Existence of theo-
rems are stated and proved for boundary value problems for piecewise-nonhcmogeneous
bodies and for mixed problems, and their extension from the static to the dynamic case
is briefly described. A sketch is given of the application of this extension of rred-
holm's method to numerical methods for the solution of a number of boundary value prob-
lems of elasticity theory. Orig. art. has: 14 formulas, 1 figure.

Abstract In laboratory experimento on the larvae and femalcs of the
grape the effectiveness of thiophos emlsions (0.2-0.25%)
scale insect was respectively 100 and 9%, of mataphos
(0.3%) emulsions -it was 98 and 96%, in carbophoo emulsions
-it was 90-100 and 40%; on the larvae of the grape cushiou-
like worm it was 100, 98, and 70%. The death rate of the
larvae of the second hatching of the mottled grape moth
reached 100% from the thiophos dust and emulsion (10.1%),
from pyrophos (0.1%) and carbophos (0.7%). Under natural
conditions 1% dust and 0.1% emulsion were effective

against the leaf phylloxera. The larvae of the grape
scale insect and of the grape cushion-like moth died
within five days, when sprayed with carbophos and p7ro-
phos, and within 6-10 days when sprayed with thiophos
and metaphos. The length of action of the residue from
tested preparations in the laboratory was 7-12 days,
under natural conditions it waa only 2-4 days (reexamina-
tion on the beettles of the barn weevil). Burns from
pyrophos (0.3%) and metaphos (0.4%) were observed only
on the young leaves of grapes.

ABSTRACT: In order to characterize the enzymolytic 3oil-activity
one usually investiKates the behavior of the animals that.
populate it, especially the saprophytes, separated in
bacilli-culture, These researnhes played an important part
at the investigation of impoi nt soil-qualities- Of
especially great importance .6 the determination of the
species of the organisms Thai" ppul.Rte the soil. An index
of species already allows to 3..dge the processen which
may go an In their zone under certain condJtion3.
Experiments showed that the soil, an a rule, is of greAt
enzymalytic activity which is also prcved by the works
of V. F, Kuprevich, A. S. Sharov, A. V~ Baranovskaya,
8, M. Mashtakov, I. I. Kanivets, T. A. ShcherbRkova,
Card 112 P~ A~ Vlasyuk, and others. It turned out that the

enzymolytic activity of different soils is not eq 'ual. That-14
wero found out essential differences in the ~ncywulytic
activity of old arable soil, covered by medows or gross-
aowinCs, as well as of forest and other soils, covered by
natural vegetation, But up till now it was not poqtjible
to detennine correlation of nuch kind which on the banin
of the feriliPnt-activity aLlown to Judge the harvest-yield
to be exsoected. One cannot deny that the enzymolytic
activity of the soil-animals plays an important part in
preparing the fertility wherein one uuua':ly assumes that
this is a matter of bacteria and funFi. Recently the
author pointed out that the roots of plants have the same
effect, Finally he mentiones that many questione still r~--mtt-.n
unsolved.

N. F, Kuprevich)
Based on the objective photumeter (GOI) of Prokof'yev design, a self-
recording microphotometer was constructed for the self-recording of spectro-
grams in the blackening scale. The optical part of this photometer is some-
what different: instead of two light beams, only one is left, covered by
a cellophane fiJi,-, -with a rectangular aperture in the middle. The light
scattered from the cellophane film is of a dark red color to which the se-
leniun photoolement is not responsive. The scattered light replaces the
second team and illuminates the photoplate while it is placed in the photo-
meter. The area to be measured is set Into the aperture and one proceeds
in the usual way. The recording is made, on oscillographic paper 40 m long
and 12 cm wide, by means of a mirror galvanometer, type 1,121, with a time
constant of 3.9 sec. The equipment is supplied with current from the al-
ternating network curient and the voltage is stabUized by a stabilizer.
