PURPOSE AND COVERAGE; This book is intended for a vide circle of engineering
and technical vorkers. The authors compile and classify data on experimental
underground nuclear explosions in the USA, in the period 1951-1962. Infor-
mation on projects for the application of underground explosions for indus-
trial purposes is also given. -The authors express their gratitude to Corre-.
sponding Member of the Academy of Sciences USSRN.A. S%Jgyjddx.fbr valuable
advice given them at the time the book vas written. The authors am amteful
also to Z. I-Yefimova, who helped in the preparation of the manuscript.

The author gives a proof of the following theorem, supple-
menting a result of Alexandrov in the paper reviewed above.
Let E be an arbitrary r-dimensional set contained in a
Euclidean or a Hilbert space R, Let V be a closed subset
of B of dimension not exceeding r-2. There exists a con-

Title : Now corelations of the duality In the open 3-cU
Periodical : Dokl. All S'3R, 96, Ed.,5, 925 928, June 1954
Abstract The article deals with the proving of a general theorem which is
supposed to answer the question on duality of ordinary groups with
compact factor-groups (4C' ) of an open set A when the ordinary groups
are taken along the discrete domain of coefficients (factors); other-
wise.1 the theorem is to show whether or not those groups can be ex-
pressed through topological invariants of an additional set. Two

hydrates and their solid solutions) interact little with the medium. He

calculation of the free energy, entropy, and the specific heat. By his

parallel fields at room temperature, and to determine the constant b of
specific heat and the spin-lattice relaxation time y as a function of the
concentration of magnetic ions. In accordance wit'.11 the thermodynamic
theory formulated by I. G. Shaposhnikov (Ref. 3), the following relation

If the difference between Ys and ? is sufficiently large, it is possible
to find a frequency at which the first term of equation (7) becomes
negligibly small, and absorption only depends on the inner relaxation:

introducing diamagnetic ions into the paramagnetic substance. Single

absorption curves for chrome alum with various concentrations of
majnetic ions. A good agreement with equation (8) was found. Fig, 2 VX

decreases with magnetic dilution, and approaches the value
(b/C)e = 0.22-106 oersteds for chrome alum, and (b/C)e = 0.40-106
oersteds for manganese sulfate. Since the total constant b/C and its
electric component (b/C) are thus known, it is possible to calculate
the magnetic component o? the constant from b/C = (b/C)m + (b/C)e~ The

The Existence of Oscillating Motions in S/020/60/133/02/14/o68
the Three-body Problem iDig/BO60
body 3 is constantly on the Z-axis, if the two bodies 1 and 2 move in an
ellipse in the XY-plane. A system of this type had already been investi-
gated by Lt 11. 0 orov. The whole system can be described by the two
parameters r and p of body 1 with respect to the 1. axis. Evidence is
given that a value v exists for each T value (v is the velocity of body
3 in the &-direction), so that in the course of time body 3 passes
through the zero point for an infinite number of Umes. The existence of
this oscillation is proven with the aid of two theorems. Finally, the
case of a finite mass of body 3 is dealt with. BodY 3 with mass m (bodies
1 and 2 both have mass M) is shown to pass through the center of gravity
of bodies I and 2 for an infinite number of times in the course of time.
It follows that m does not exceed a certain value a'. There are 2 French

Thermodynamic properties of the spin system of cupric

PI~RIODICAL: Fizika tverdogo tela, v. 4, no. 4, 1962, 861 - 865
TEXT: The thermodynamic properties of the spin system of CUK 2(SO4)2 6H20
and CrK(SO 4) 12H 20 are of interest to low-temperaturi~ thermometry. With
the aid of siatistical thermodynamics, the entropies and specific heats of
these systems have been calculated with the representation of free ions in
magnetically rarefied systems. The values agree ,-;ith measurements. The
s~Decific heat of the spin system of cupric potassium sulfate is due to the
electron magnetism, and at low temperatures to exe -hange interaction. The
contribution of hyperfine splitting to the specific heat is small. There
are 3 tables and 06 references: 4 Soviet and 2 non-Soviet.

TEXT: The entropy of the spin system of copper potassium sulfate is
calculated and compared with the measured data using.the statiatical
formula SIR - ln(l+e_Q) + (Q/T) [e_9A1(e_~1t.+ i)] taken from an earlier
work (FTT, 4, 862, 1962). Complete agreement was foucd when the absolute
temperature was T - aT* + Q*, where a . 0.965*is an empirical coefficient,
T* is the temperature measured and QW the constant of the Curie-Weiss law.
In the temperature range where the magnetic susceptibility x C/T and
where Q* >, T, i.e. where the Curie-Weiss law is violated, T T* + Q*.
These relations show that up to T* - 0.2560K the eiinpirical and absolute
temperatures coincide, i.e., that up to this tesiperature the Curie law is
satisfied. At lower temperatures Q* m 0.0280K, as follows from T - T* +

Moment of a systeln at T= OOK is'independent of temperature; M Since further
Japplication of external magnetic field H on a paramagnet doev not alter the order
jof the system, and only produces.precession of spins in the direction of field H,
from discontinuation of thermal motion. at. absolute zero it follows that the magnetic

TITLE: Silicon Zener diodes under energy-balance operating
conditions
PERIODICAL: Pribory i' telchnika eksperitilenta, no. 1, 1962,
132 - 133
i7 _.'_KT: Silicon Zener diodes can easily be temperature-
compensated, in which case their stability can 0be as high as
0.00111~i for the temperature range from 10 - 50 C (Ref. I -
J.A. Uiandler - Electronic Engng., 1960, no. 2, 78). However,
these diodes, when used as reference-voltage sources under
ptilsed conditions, suffer from the disadvantage rhat a com-.-
paratively large thermal voltage drift occurs during the first
few minutes after switching-on. It is suggested that this
difficulty can be overcome by feeding a suitable current into
the diode in the forward direction during the off-period. The
current should be such that the power dissipated in the diode
when operating as a reference-voltage source and when conducting

in the forward direction should be equal. It A%ra:3 found experi-
mentally that by employing this method the thermal drift could be
reduced to 100 -~LV. Diodes operated in this manner can be used
in digital automatic compensators and for genera-ting rectangular
pulses of high-amplitude stability. There are 3 figures.

ABSTRACTi In the past, the construction of devices with several stable states was baded
on consecutive joiaing of binary trIggering elements. Consequently, such circuits were
characterized by it large number of tubes and transistors. The present paper explores the
feasibility of systuns in which the nu miber of stable states does not depend on the number
of tubes or transitstors. Such circuits are possible if one utilizes nonlinear elements
having several dejareasing segments along their respective volt-ourrent characteristicst
