directions are rotated relative to the (x, y)-axes through an angle r: -h e
contours of holes which are free of external forces are given by parameLr.L,
equations in polar coordinates. The minimum (critical) values of p and q
are sought at which a sharp point of the hole contour (an evident stress
concentrator) &tarts to advance. A method of conformal mapping is used
in determining the stress functions for boLh hole contours and the components
of the stress tensor in the vicinity of the sharp points. The relationships
of the theory of equilibrium cracks are used in deriving formulas for the
critical values of p and q. The particular case when the plate is suri.ected
to one-directional tension perpendicular to the x-axis (a = 71/2) is
analyzed, and formulas for critical p and q are derived. The obtained
formulas are compared with approximate formulas for analogical stresses
previously obtained by V. V. Panasyuk (Dopovidi AN UkrSSR, 1965, p. 868) for
stress concentration around cracks on the edge of a circular hole, and fair
agreement is found between them. Orig, art. has: 1 figure and 19 formulas.

ABSTRACT: (On the basis of the results of an earlior article (The Destruction
of Brittle~Bodios in the Plano Stressed State, Prikladnaya Mokhanika (applied
MochanicsT, 1. 9. 1965), an analysis is performed of the problem of the
limiting equilibrium of a brittlo plate with an aperture In the form of a
i hypocycloid with n branchos, when the plate is subjected to biudal extension
And conpronsion. The case of a plate with an aperture in the form of an*
astroid Is analysed in detail. For this case, a diagram of the begira-dnZ of
brittle destruction of the plato is construct(,d. The method for solution
presented in the earlior article consists of first determining. with the given
external stress, the distribution of elastic stresses in the neighborhood of
the corner points of the plate, then, using the limiting state equations,
computing the limitiN load for.the problom and constructing a diagram of
limitin equilibrium of the plate in the general oase of plane stroasod stato.

ABSTRACT: The Physical Institute im. Lebed*v has developed since 1950
luminescent substances of permanent action activated with
various radioactive isotopes. After investigations of numer-
ous phosphors it was established that the ZnS-Cu phosphor is
most luminous at beta-excitation.
The following conclusions resulted from these investigations:
1. Sr go isotope, and in some cases C~137 isotope, are
recommended for luminescent substances of permanent actiont
2. Luminescent substances activated with Sr 90 can have a

Errors involved in three basic methods of massive determination of stellar
radial velocities by means of an objective prism are analyzed. Discussed are
the absorption method, the method of length of the spectrum, and the method
of turninp. the prism. The crrorv are ascribed to extrn-axial effects of the
prisms and may be reduced by the use of a prism with strAight view. Rebuliz
are presented in two tables and further improvement of the method is envisared.

New thermal insulating material in power engineering
Tekhikp-, no. 1p 1961, 38-40
TEXT: The article deals with the problem of replacing mineral wool,
sovelite and vermiculite, used for thermal insulation in Soviet-made
boil6ra in operation in Bulgaria. In view of a shortage of the above-
mentioned materials and a tendency to rel4ace foreign products by domes-
tic ones, Bulgarian designers had to consult A. I. Folkanov, a Soviet
specialist in insulating and lining boilers from the Barnaul Boiler
Plant. According to a report submitted by A. J. Polkanov, Nlgarian

The technological characteristics of perlite concrete, consisting of a
14% solution of abietic rosin, cement, water and perlite &and, are also
given. Due to the great similarity of the technological data of perlite
concrete, BOTelitoe, and mineral wool and the results of analysis, the
perlite concrete can be used for thermal i 'naulation of gas, air and steam
