Title :Electric reaction of the cerebral cortex in skin diseases
Periodical ;Byul. eksp. biol. i med. 7, 37-40, July 1955
Abstract :Author reports on her studies of the effect of peripheric irri-
tation on the electric potential of the human cerebral cortex
under normal and pathological conditions. She used an encepha-
lograph to study healthy persons, patients with light-induced
dermatoses, and those with "tactil" and painful skin irritations.
Author determined that even in fairly insignificant and just
adequate irritations of the skin changes in the electric activity
of the cerebral cortex are noticeable. 'hanges in the reactivity
of the higher divisions of the central liervous system during skin
irritations do not depend on changes in disease conditions. Cer-
tain electric reactions of the cortex to irritations may result
in impulses to healthy as well as diseased parts of the skin. 17

ABSTRACT: Axial compressors used in gas turbines and elsewhere are
often :ceqtUred to operate stably and efficiently over a wide
range of conditions. But the characteristic curves of axial
compressors are steep and have a narrow range of change of
output for constant speed. Therefore, in designing axial
compressors it is often necessary to investigate the possi-
bility of extending the range of stable operation of the
compressor by changing the position of the boundary of pump-
ing and changing the steepness of the characteristic. Little
work has been published on this question. There are two
main reasons why the characteristic curves are steep and the
output range at constant speed is narrow. The first reason
is the great sensitivity of the characteristic of the blade
profiles to change in the angles of attack. The second
reason is associated with compressibility of the working

This article considers several possibilities for
improving,the compressor characteristics by appropriate
selection of design parameters of the initial stages. T1B
problem is examined in its simplest form leaving aside the
question of efficiency and using an approximate method of
investigation.
A diagram is given of the dimensionless triangle of
velocities of a stage, and corresponding mathematical
expressions are derived for the coefficients of flow, of

shown that ~~~eristlc's'of ~ih~oretical Sead-Iiinus

the origin and through certain other points so that the

characteristicsof multi-stage compressors it is advisable
to increase the head in the initial stages,. Tests results
on various compressor stages show that the regibn of stable
operation of a stage is usually characterised by a single
value of range of change of angle of attack. -Test results
are given for stage characteristics with various degrees
of reaction and it i& found that the range of stable oper-
ation diminishes with reduction in the degre!q of reaction.
The experimerts confirm the theoretical conclusion that a
stap a greater degree of reaction will have a greater
ran.-SeO*tput and head than a stage with a small degree
of reaction.. It is also of interest to compare character-
istics which can be obtained by arranging stages with
different values of initial reaction. using the--same blading
on the runner. The corresponding characteristics are
plotted. A graph is also given of the change of--de-gree of
reaction with change in the conditions of operation and a
graplf of the chAhge- in'the theoretical hea& cmffinient-and

It is concluded that the compressor characteristics can be
improved by proper attention to design and in particular

that -the steepness of the head cbgracteristic of the stage
is greater the less the initial values of the coefficient
of flow and of the coefficient of head of the stage. When
these initial conditions are constant, and the difference
between the angles of attack are approximately the same, the
range of stable operation of the stage is increased by
incre-asing the degree of reaction.

PERIODICAL: Zhurnal Eksperimentallnoy i Teoreticheskoy Fiziki, 1958,
Vol- 34, Vr 1, pp. 233-234 (USSR)
ABSTRACT: The influence of He3 dissolved in He II upon the film flow
is, as is well-known, reduced to the decrease in the flow
rate. It was of a certain interest to investigate this fact
more thoroughly and therefore the authors made tests with a
solution of helium-isotopes with a helium content of 1,5;
497; 7,0 and 9,6 %. The apparatus used for these tests
consists of two elbows of a thin-walled capillary tube
(diameter i,oS mm) of equal leni;ths communicating over a
helium-film, The film flow rate R = v6 was measured by the
measurement of the rate of change of the liquid level in
one of these elbows. In this connection v signifies the
rate of the motion of the film and 6- the thickness of the
film. The temperature interval immediately following thek-
-point was investigated. The results obtained here are
Card 1/3 illustrated in two diagrams. One of these diaarams

illustrates the dependence of the fili.,i flow rate on the
tenperature and the other diagram -3the dependence of the
film flow rate on the content of He . AccordinE to the
results found here the film fl?w rate increases with
increasing concentration of He . When havint~ data on the
dependence of the density on the temperature for the
solutions of the helium-isotope8, the following conclusions
can be drawn: The filr,,i flow rate in the temperature range
investigated here is directly proportional to the density
of the su erliquid component: R = A~s/~ , where A -
- 3,2.10_~ cm3/CM8ec. moreover the temperature of the phase
transition He I - He II for the solutions gi-ven here might
be determined from the beginninC; of overflovinG over the
film. The values obtained in this conziection are in satis-
factory agreement with the analogous results obtained by
other methods. There are 2 figurcs, 2 tables, and
references, 4 of which are Slavic.

experiment was made on liquid He ,contained in the cavity between two'
coaxial cylinders (ring-resonator). This resonator can be rotated about
its axis of symmetry. The emitter and the detector for secondary sound
were installed on the inner cylinder. A special device enabled the
resonator to be rotated uniformly. The emitter was fed by a highly

raised to 2.250K bY stopping evacuation. The resonator was set in
motion (00 . 0.96 sec and after 3-4 minutes Ile was again pumped out
at a rate of 2 mm Ug per minute. The amplitude of secondary sound war
measured at the moment of passing the previously fixed temperature. The
same measurements were also made with motionless He. The measurements
at a fixed temperature of 2.150K showed that the maximum amplitude of
secondary sound ddes not change, i.e., the formation of vortices slows
down. The amplitude becomes lowe!r when the temperature is raised
somewhat above the ;~-point and is then again reduced to 2.150Y. without
the resonator being stopped. The measurements at fixed tempgrature of
2.090K give another picture: at the first reduction of temperature the
amplitude of secondary sound becomeslower by 2V;'o. The same reduction is
reached after 1-5 to 2 minutes rotation at the same angular velocity when
the tie is kept at a temperature of approximately 2.090K. The time that
elapsed before this slowed down the formation of Onsaller-Peynman
vortices is estimated to have been 4 minutes(at 2-15010-

in which second sound could propagate in a radial direction. A
second axial resonator was constructed, in which the second sound
could propagate along the axis of rotation. The experiments have
shown that in the immediate vicinity of the phase transition point
the rotating helium II becomes foglike, as a result of uniform dis- i
tribution of' vortex nuclei. It is deduced from the experiments that!
initially there is formed an isotropic mass of vortex nuclei, which
gradually be-come aligned into a system of vortices oriented along
the axis of rotation. The relaxatlon times were measured for dif-
ferent rotating speeds and for different degrees of supercooling,
and it Is concluded that the relaxation time of the classical type

ABSTRACT: To check on the cause of the increase in the density of helium II when
'the latter is rotated, first observed by E. L. Andronikashvili and G. S. Tsakadze
(ZhETF Pis'ma v. 2, 278, 1965), the authors have measured the velocity of first sound
in..rotating helium II at temperatures 1.40 - 2.10K and angular velocities 0 - 70
..se.c71, Since the results of Andronikashvi3-i and Tsakadze disagreed with those ex-
f:pec ed under the assumption that the condensation is due to centrifugal forces, the
advanced the hypothesis.'that the condensation is due to the presence of
.:,quantized vortices themselves. 'The measurements were made by a procedure whereby
~,.S~sbort sound pulses were transmitted to the investigated medium and the travel time
..,6f these pulses along.a certain segment of definite length was measured. The results
show that within the range of angular velocities and temperatures measured, the speeds
of sound remains constant (vithin 1%) at all speeds of rotation. This refutes the

is solved by the solution of the tasie equations of
elasticity theory with the aid of the Fourier method. The

TEXT: The -authors report an exact solution of the axially symmet-
ric Droblem of-the theory of elasticity for a hollow cylinder of fi-
nite length. An arbitrary load is assumed to be applied to the side
surface of the cylinder, while normal displacements and tangential
stresses are given at the ends. The solution is given in the form
of Pourier and Fourier-Dini series. A numerical example of the so-
lution is given. It is pointed out that the previously published so-
lutions ivere approximate. There are 4 figures, 1 table and 12 refe-
rences: 10 Soviet-bloc and 2 non-Soviet-bloc. The references to the
Miglish-language publications read as follows: MI.A. Binnie, Philoso-
phical Magazine, London 212, 1941, 336-347; D. 'De Allen, L. Fox and
