Radiation Measurements During the Flight of S/020/60/136/002/013/034
the Third CosmicRooket -BO19/BO56
October 4,:19599 to.Ootober-18, 1959-~The trajectory of the rocket was in
practical agreement~with.that of the first and second cosmic rocket. From
a comparison of the readings of the various counters, the authors. conclude
that the intensities of the~particles recorded by the instruments depend
on the absorption in the container walls. Measurements in the interplane-
tary space showed that the cosmic radiation on the.boundary of the
terrestrial,magnetio field is very.strong; only individual small'fluctua-
tions were recorded. Finallyq the-agreement existing between the recorded
intensities and those of a monitor-are dealt with. From these considera-
tions the authors.draw~the conolusionthat the weak variations in the
time from October 4 to,October 18 are-in connection with the variations of
the miagnetic fields in the-solar system and the interactions among the
latter are connected-with cosmic radiations. There are 1 figure, 1table,

The angular and energy distributions -of the electrons in the showers are
adopted from the cascade theory of electron-photon.showers. The shower
axis meets,the earth's surface at the point'O (Fig. 1), the radiation
pickup is at D, the figure OBCD.lie's in the drawing plane, the figure;-
OOIAIB in a plane perpendicular to the drawing plane. The intensity of
light generating electrons with energies between E and E.+dE at'the point'
D is determined. Numerical results obtained for showers from pridary pro-,
tons and photons of variouslenerg3*.es are given (Table). There are
4 figures and I table.

ABSTRACT: At the.-end of 1965 and beginning-of 1966 two.Soviet space,
stations, Zond-3 and Venera-2, were in space simultaneously measuring
cosmic ray intensity. The first was in motion away from the Sun and
;the second toward the Sun, which made it possible to determine both
variations in the intensity of cosmic rays and their dependance on the
Idistance. from the Sun (L.e., their radial gradient). Data obtained by-
STS-4-type gas-disch e craft'revealed the
,%rg counters onboard the space
Iradial gradient as (3-1 +0.4)% per 1 astronomic unit. The radial

gradient was irregular; this phenomenon was attributed to changes in
the character and magnitude of.-the Forbush effect. Detectors of the
.n-p type onboard the space., stations measured the radial gradient of
protons with energies of '1. .5,Mev. In addition to a sharp temperature
increase, the detectors revealed a very stable and time-independent
noise which exceeded by about 10 times the possible noise of,high-
energy particles. It was-also~found that the intensity of protons in-
creased in moving away from the Sun. Whpn the distance from the Sun
was increased from'130 x 166~ to 190 x 101 km, the intensity of 1-5-Mev
protons, whose origin is known to be-solar, increased 5 times. A mech-
anism is proposed-for 'explaining this paradox. The nature of thq radial
gradient may possibly be explained by Pa,rker.'&diffusion theory. I

ABSTRACT: Activity of,sodium in Na-Pb alloys and sodium vapor pressures over Na-Pb
alloys containing _15.7-S7.2 at Na was measured in the 660-11000K range. The Na ac
tivity was determined by measuring the electromotive force of the following system:
(-)Na/electrolite containing Na ions/Ka-Pb alloy (+). It was found that for a given.,
temperature, the activity of sodium is a linear function of the sodium content in Na-',
-Pb alloy., The sodium saturation vapor-pressure (P over I;a-Pb alloys at a given:'

on the graph of the dependence of the discharge voltage on the gap
magnitude. It,ia,conspicuous.for tI.ie fact that in this interval.the
trend of the.curve de* -Yealtly-on the discharge current force

(51 7, and 15.ma). This interval-lies in region C and is character-
ized by the maxim= sensitivity'of- ,Yl

the gap. It is evident-from the.current-volt.age characteristic that
for gaps of about 0.1 mm the discharge voltage also hardly depends
on chance variations of the discharge current force. A gap of-.about
0.1 mm. is thus the most:favorable for anemometry. It was establish-
edt too, that spherical electrodes are .more advantageous than.point-~
ed ones. All investigations-weremade irith the stablest-electrodes..'

In regard to the function of the gallbladder and extrahepatic billary tracts. a follow-
up of 50 patients with gastric interventions for ulcer and cancer demonstrated the
gallbladder to be enlarged in 11 patients, the time of its emptying to be lengthened
in 13, no gallbladder shadow to be seca during cholecystography in 13 and stones to
be present once.- The shadow of the gallbladder was either non-distinct or reveal-
ed its abnormal low, position and shape deformation in 10 patients. Seven patients
complained of pain. The aforementioned symptoms were present In various com-
binations. Only 15 patients had a normal gallbladder. In 5 patients late examin.
ation disclosed organic changes; 3 cases of chronic cholecystitis, one of &all-
bladder empyema w%d one of cholelithlasia. These data lead to the conclusion that
gallbladder functional Impairment. wA in a number of cases organic changes, are
fairly often encountered &a sequoias of gastric resection. Functional gallbladder
and billary tract disorders are not only present in the first postoperative days but
also many years after.
