TBXT: By means of apparatus placed aboard the second satellite the
flow of particles exceeding the flow of cosmic rays was recorded.
Near the equator the mean flow equalled 1,2 particles cm-2 sec-1.
being 3.3 particles cm-2sec-1 in high latitudes. Regions with an
anomalously high radiation intensity include the area of the Atlan-
tic Ocean's southern part (250 and 500S, 00 and 550W). A Southern
anomaly, situated between 50 - 650B and 500W - 400E, was detected
at a height of 340 km. An increase in the intensity was recorded in
the northern hemisphere in the area 60 - 650N and 130 - 1700E. This

diation belt. In the authors' opinion the South Atlantic and Sou-
thern anomal4ee are connected with the existence of large negative
magnetic-anomalies in the southern hemisphere, i.e. regions in
which the magnetic field-strength is less than the normal intensity
for the given geomagnetic latitude. tAbstractor;s note: Complete

Equipment for investigating the ... D045/DI14
of cosmic rays is given in fiG. 1. The Cherenkov counter can be used for
investigating temporary changes in the intensity of the nuclear component
and the dependence of this intensity on distance from the Earth. The advan-
tages of the counter are that the radiotechnical device used is relatively
simple and that a sufficiently larGe number of particles ctui be registered
per unit of time. The disadvantage of its use is that the quantity of IJUht,
divided in the detector, and the number of photoelectrons taken from the
cathode of the photomultiplier is small, and consequently the value of the
output pulse is small and large statistical fluctuations occuro A device
for measuring the characteristics of Cherenkov counters and several aspects
of calibration are described and illustrated. It in stated that the instru-
ments for measuring the nuclear components of cosmic raaiation installed on
the first and second space rockets had an additional channel designed for
registering radiation in an area of increased radiation intensity4 A sharp
increase in intensity was observed at distances of 27o103 km (first rocket)
and 1741o3 km (second rocket) in an area later called the inner radiation
belt. A block diagram of one version of the electronic system is shown in
fiG, 17. As can be seen from the fiL-ure, information on the condition of

TITLE: Study of charged-particle Intensity during the
flight of the 2nd and 3rd SputnikB
SOURCE: Akademiya nauk SSSR. Iskusstvennyye sputniki

TEXT: During the flight of the 2nd and 3rd Sputniks, the flow
of charged particles at altitudes betiveen*187 and 339 km and
latitudes of -65 to +65 was recorded by means of a telescope
consisting of 2 rows of gaB-discharge counters; the telescope was
part of measuring equipment for cosmic rays. As a result of the
measurementsl the intensity of the charged particles and its
latitude dependence were determined. The counting rate N 0 and

the global intensity J g1 at various latitudes are listed in a
table. It was found that at all latitudes the recorded intensity
was several times higher than the intensity of cosmic rays re-
corded in the stratosphere and in free space beyond the earth's
magnetic field. This difference is particularly noticeable in
the region of the geomagnetic equator, where the measured inten-
sity was six times that of cosmic rays. Several regional anoma-
lies of intensity were observed, apparently related to the anoma-
lies of the earth's magnetic field. Por the entire track of the
space-Bhips, detailed graphs were made of the time dependence of,
the intensity and hence of its dependence on geographical coor-
dinates and altitude of the space-ship. Prom these graphs, mapo
were made of the intensity distribution on the earth's surface.
It is noted that, with repeated passage of the space-ship above
the same terrestrial point and almost same altitude, the recorded
intensity differed sometimes from that on the first passage; in
some cases, the intensity was almost double. This difference

was particularly noticeable at high latitudes. As the oriunta.-
tion of the apparatus changes during the second passage, this
difference in intensity may not be real. The obtained equi-
intensity lines for the south-Atlantic and southern anomalies
constitude a slight refinement to the earlier obtained data (ill
the references); the maximum number of counts in the southern
anomaly was 60 per second, and in the south-Atlantic anomaly it
was 70 per second. The anomalies are particularly great in the
Southern Hemisphere. The intensity distribut:ons in the anomaly
regions, recorded at altitudes of 306 - 339 kDi and at altitudes
of 187 - 265 km during the two flights, differ from each other.
This difference is apparently due to the different flight-
altitudes. The connection between the anomalous structure of the
radiation belts and the anomalies of the earth's magnetic field
is evident; it would be premature, however, to assume that the
regional anomalies of the magnetic field on the earth's surface
have a substantial influence on charged-particle flow up to
altitudes of 200 - 300 km. The many anomalies in the South- and

North-Pole regions, their disposition and variation, suggest
that these anomalies are the edges of the outer radiation belt
of the earth. The latitude dependence of the intensity is shown
in a graph (for the Northern Hemisphere); it is noted that,at
high latitudes, the increase in intensity ceases. The obtained
data on the intensity distribution give evidence of the edge
effects of the radiation belts at 200 - 300 km altitude and of
certain peculiar features not observed previously. In particular,
the great temporal anomalies are noted; thus, the "northern ano-
maly" recorded on August 20, 1960, at 7 hr. 40 min. (world time)
and the south-polar anomaly recorded on December 1, 1960, at 14
hr. 22 min. These anomalies are apparently due to solar activity.
The line of least intensity (the "radiation eqiaator") is shown
in a figure. With regard to the composition of the radiation,
it is likely that the increase in the counting rate (as compared
to that from primary cosmic rays) is due to protons with E
p
60 Mev; although no definite conclusion is possible as yet, it
Card 4/7

333o5
B/560/61/000/010/003/016

is assumed (as a working model) that the inner radiation belt
if formed by protons and that the number of electrons of energies
higher than --.-,2 Mev is small. The above results confirm the
existence of a high-intensity region down to 200 km altitude
(from 1000 km)o On the other hand, the radiation at 50 - 150 km
is practically independent of altitude. The altitude dependence
of the intensity (for 200 - 2000 km) is shown in a figure.
Tentatively, the altitude h and the atmospheric density e can
be expressed by the values:
h, km 100 150 200 300 400 500

On the basis of the incomplete data available, the internal
radiation-belt in the equatorial region for altitudes above 400
600 km can be approximated by a very simple model, where only
ionization losses are taken into account. At higher latitudes,
the pattern is more complicated; it becomes necessary to render
more precise the composition, spectrum and altitude-variation
of the charged particles. At altitudes below 400 600 km,
considerable deviations from the formula J - p- occur, This
is due to diffusion of the particles in a direction transverse
to the magnetic field; this diffusion mechanism is related to
collisions between particles. A second diffusion mechanism
exists, related to the presence of electric fields B which
cause particle-drift. The diffusion processes require further
investigation, Finally, the radiation dose is estimated beneath
a layer of matter of the order of 4 gm/cm-2 at an altitude of
200 -, 300 km. Assuming recorded proton energies (in the equa-

torial region) of E >
p 60 Mev, the daily radiation dose consti
tutes approximately 30% of the permissible dose. In the region
of the south-Atlantic anomaly at 300 km altitude, the radiation
dose is by an order of magnitude higher than at the equator.

cm-2 sec -1 . The charged-particle flux intensity of the anomalies in the
southern part of the Atlantic Ocean exceeds that in the corresponding
geomagnetic latitudes by two orders of magnitude. In 330 km an area of
smaller intensity separates the South Atlantic Anomaly (a "sleeve" Of 'thd
inner radiation belt) from the Southern Anomaly connected with the outer
radiation belt. The particles recorded in the equatorial area are protow
of at least 60 Mev or electrons of at least 8 Mev. There are obviously
very many particles of smaller energy in the anomalies. The line of the
smallest radiation intensity lies in an altitude from 187 to 339 km and on
the western hemisphere farther south than the geometrical equator. In.
higher latitudes, owing to solar activity, the intensity of particle
currents is subject to considerable temporal variations. The actual
mechanism of acceleration and ejection of heavy particles on the sun is not
known hitherto. There are 12 figures and 2 tables.

ABSTRACT: The article is a survey of'reported experimental data on the composL-
tion of cosmic rays. The following groups of nuclei (other than protons and
alpha particles) with charge Z >,3 are considered: (1) light nuclei with
charge 3.4 Z 10 (group 11). The symbol S is also used and designates
nuclei with Z ),6 (S7-- M*H). It is ohown that fluxes of different nuclei
(including protons) skould be -compared for a given-value of their hardness. As
a rough eneral rule, nuclei of elements with atomic number Z are Z times more

i frequent in cosmic rays than in nature. Difficulties iwvolved in meaSurtmots
i of fluxes of the different groups of nuclei are described. High-altitude ex-
periments definitely indicate the presence of lithium, beryllium, and boron
nuclei (20-307. of the quantity of heavier nuclei) in the primary component of
cosmic rays in the vicinity of the earth. Findings concerning the electron-
positron component of cosmic rays are discussed, and the chemical composition of
solar cosmic rays is considered. Differential energy spectra of protons and
nuclei and their hardness spectra are analyzed. On the basis of the body of
data accumulated thus far it is ncw possible to state that not only protons,
but also multiply-charged nuclei are accelerated on the sun; however, this
mechanism of particle acceleration is still unknown, and several such mechanisms
may exist. Orig. art. has: 14 figures and 3 tables.

ABSTRACT: Results of work conducted with the help of satellites and rockets in
'71958-63 for the purpose of studying the nuclear component of cosmic rays are pre-
~sented. The intensities of various nuclei group streams are given, and the upper
'Jimit of the ratio of nuclear streams with Z z 30-h0 to that with Z.z 15 is found
to be 0.01-0.03%. The ratio of a light nuclear (group L) stream to the stream of
:~nuclei of.group S ac M + H was found to be 31.0 + 9.6%. The short-period intensifi-I
~cation of nuclear streams is considered in relation to solar chromospheric flares.

iABSTRACT: Included in the instrumentation of the Elektron-2 satellite (launched,
lian 1964; apogee, 68,000 kin) was a combination of and external counters
idesigned to register nuclear components of p~~imar cosmic radiatfon. The design and.__
Y_
;calibration of this apparatus is escribed, and some results of partielly-reduced i
:data are discussed., One ijc_1qntqrv_M1ounted on the external surface of the satellite

.type, registering at the discrete levels of. Z >,: 2', Z % 5, and Z >,. 15. All counters were
shielded and were designed to register only particles with energies ~-600 Mev/nucl
IFig. I of the Enclosure gives the basic schematic of the external counter combina-
tition. The authors detail the method used to calibrate the photamultiplier outputs:,
in terms of the Z-range of input excitation; for example, for the type'FEU-35 exterl
nal counter, the anode output characteristic corresponded to the range from Z - 4
Ito Z - 21, and the output of the 7th dynode, to the range Z - 6 to Z - 28. The
!calibration technique was to excite a SiC electroluminescent diode with a high-v91-,
tage, short-duration (4-30 nsec) thyratron pulse, providing the phototube with a
i
light input similar to a counter input. Early results from these primary particle
1counters, obtained during the IQSY, have been a useful supplement to analogous satel-
Ilite data from the 1959-1962 period, during which solar activity was undergoing the'
!transition from maximum to minimuin. Comparative results are seen in Fig. 2, which : .
I hows an almost twofeld increase in nuclear particles recorded near the solar activity
is
;minimum. Table 1 compares data from one orbit of Elektron-2 to that of the 1959 and
'1960 satellites and the 1962 Mars-1 probe. To date only data for the Z ) 15 particles.
:have been reduced enough for'statiatical analysis. A large increase in incidence of
1this size particle was noted during solar eruptions observed in the course of the
iElektron-2 flight. Orig. art. has: IS figures, I table, and I formula. [SH)

wns part of the toloscopo, also recorded very heavy nuclei with oharge numbers near

chnnuels by the internal Coxenkov counter. The counters were tcoted and calibrated
in tile laboratory with the jild of cosmic ray particles; the associated photomulti-
pliern were calibrated with f1rinbea from a SIC diode. Preliminary "sults are com-
pared with analogows data recorded with the Sneund Soviet Cosmic Rocket, tile Third
Soviet Satellite Vehiclef aid the Mnrq 1. A ntrong negative norrelation Is itill-
cated between oolar activity and the intensity of the nuclear component of the
cosmic radiation. The intensity of tho nuclear component nenrly doubled between
tile flights of the Second Cosmic Rocket in 1959 and the Electron 2 In 1964. It Is
anticipated that when thb.datn recorded with the Electron 2 are processed they will
provide information concerning the dependence of the nuclear comp:)nent on solar
.activity. A number of solar flares occurred In February and Mnrch during tile

ABSTRACT: The nature of the system mentioned in the title is marked by a
phylogenetical primitivity and consists of a pair of longi-
tudi-nal straps, which start at the rear end of the strobila and
are turned backwards in the scolex. These returning straps pass
back through the whole strobila opening at thelast proglottids
(Ref 1). As a rule one of the canals is situated dorsally and
another ventrally as to thestrobila. These canals are connected
by a: lateral branch forming a kind of rope ladder. The number
of longitudinal straps can amount up to twenty. In spite of the
fact that the number of the straps and the location of the ca-
nals is well-known their histological structure remains un-
explored. Therefore the author studied the tender structure of
Card 1/4 these canals in the case of Thysaniezia ovilla (Rivolta, 1878).

SOV/20- 123-2-49/50
On the Structure and Function of Excretory Canals in Tapeworms
At a cross seDtion of pubescent proglottids 2 canals can be
seen: a) A br3ader one at the side, and b) A canal situated
closer to the axis of the body. The latter is considerably con-
tracted in some segmente.Since the diameter of the inner width
of these cartals is not dependent upon the age it must be au-
sumed that this canal is able to contract actively in a sort of
peristaltic wavelike manner. The walls of both canals are con-
siderably different in structure. The structure of the canal
situated at the side is very primitive; it consists only of a
thin cuticula. This canal is only a longitudinal split in the
parenchyma bordered only by a thin film of the basic substan,!c
of the latter (canal of parenchyma type according to the au-
thor's terminDlogy, Pigs I a9b). The wall of the canal situated
more medially (b) consists of three coats. This property is
responsible for the contractibility. The 3 coats are: 1) A
homogeneous citicula almost twice as thick as that of the canal
situated at t.'ae side, 2) A middle coating consisting of
circularly ar.ranged spindle-shaped cells of contractile type,
which form a continuous layer of muscles, 3) The outer coat
Card 2/4 bordering the surrounding connective tissue and consisting of

SOV/20-123-2-49/50
On the Structure and Function of Excretory Canals in Tapeworms
longitudinal contractile fibers of the cable type (as described
by the author in reference 2 for flatworms - Trematoda). The
canal is of vessel type according to the author. The lateral
connections of the canals belong to the parenchymatous type
(Fig 2). on sections tender little tubes become visible, which
open into the parenchymatous canals. They, too, are only
cuticularly coated. The little tubes convey the excrements from
the protonephridial cells to the main collector. The canal
situated at the side, the walla of which are not contractile,
serves as such. The author succeeded in finding connections
(anastomo3es) between the canal situated at the side and that
situated more medially. The latter has an effect like a pump
serving for the conveyance of excrements through the whole
strobila. Thus, the transport of the excrements is an active
process, which is rendered possible by the contractibility of
the median -anal vessel type. There are 2 figures and 2 Soviet
references.

ABSTRACT: The trematoda ontogeny consists of a series of unequal elements.
One may refer to these as phases of the life cycle. Thus
several trematoda in the parasite phaDe in a mol'uak may pass
over from the &age of the mother sporocyst into the stage of
the daughter sporocyst, then into the Redia st;,ge, and final-
ly into the Cercaria stage. The trematode which is in a certain
ontogeny stage can pass over from one phase (from a parasite
phase into a nonparasite one) into another one (Ref 1). Sporo-
cysts, Redia, and Cercaria form biological stimuli in the
organism of the intermediate host and cause a certain response
reaction above all in the inner tissues of the place where
the parasite is. The trematode mentioned in the title lives

istic of the tissue reaction of the mollusk that it is bound
to be a protective reaction and useful for the mollusksthem-
selves; the survival of the parasite larvae is, however, to
a certain extent secured. Otherwise this species would not
exist any more. The smallest most recent sporocysts were
strikin '- among the numerous stages of the parasite found by
the authors. They were surrounded by a layer of basophilic
amoebocytes. The latter are little differentiated elements
of the connective tissue of the mollusk (Ref 3). In earlier
development stages they are fused to a coencytic symplast
which expresses the defensive function of the internal tissue
of the mollusk (Ref 3). Young sporocysts can simply divide into
2 or more parts (Pig 1; 1) and form a complex. Around this
complex a common connective tissue capsule is formed. The
symplast expands with the growth of the sporocysts. Its proto-
plasm becomes thin, and the cores lie in one layer. Now
basophilic amoebocytes settle at such places. The symplast
cores are capable of amitotic separation. The protoplasm mass
is gradually reduced and decomposes into fibers. Individual
Card 2/3 fibers then contain the cores (Figs 1, 2). The mentioned capsule

forms a defensive reaction of the interior of the mollusk
against the introduction of the stimulus. The thin loose-fibrous
capsule does, however, not inhibit the penetration of the
trophic products into the parasite larvae. Pigure 2 shows
a capsule. Then there follow vast lacunae filled with tissue
fluid. A solid envelope is formed only when the parasite perish-
es. This specific defensive reaction was worked out in the
course of the evolution. .11 solid envelope would have killed
the parasite and extinguished the species and furthermore
blocked the exit of the Corearia. There are 2 fi,,,,ures and
3 Soviet references.

ABSTRACT: The authors show how the method of the model potential can be used to cal--
culate the binding energy of ionic crystals. The method consists of using a density
matrix which takes into account the overlap of all the functions of the nearest neigh-
boring ions. A concrete example in presented using the NaC1 cr
_rtal with values ob-
tained for the parameters of the model potential of the free Na ions. The binding
,energy as a function of the distance between ions, t~e equilibrium ion distance, and
the compress-Mility are all calculated and listed. The results are in good agreement
with experiment. Advantages claimed for the method ~f the model potential is that it
is relatively simple and does not call for the calculation of each individual term
separately. Orig. art, has: 11 formulas and 2 tables.

Abstract :A counter telescope without absorber was use& to measure the intensity of
cosmic rays at an altitude corresponding to jL-*e9sare of 300 mb. Twenty-
two flights were made'near Moscow. The error ift each measurement was 0.3%.
The observed deviations from average amounted to approzimately 1% (a Magi-
mum deviation less than approximately 2%). The results were compared with the
global intensity of the hard compo"nt of cosmic radiation at sea level. Thd
correlation coefficientirdbtained where 0.43 :r- 0.2 for Moscow and 0-73:t 0.1
for Yakutsk is due to a more accurate allowance for meteorological corrections
in that station and tb the world-wide character of the observed variations.
Inasmuch as the measurements were carried out at a solar-activity minimum, the
variations observed were considerably less than those observed prior to 1949
(the amplitude of which was 5 -- 10%).

of a comparatively pimple apparatus conststing of a counter and ion!?a-

of the primary cosmic radiationq b) the variations of the multiply char-
ged component of the primary cosmic radiation which consists of holilim
nuclei and heavier atcms, a) the geomagnette field at great distancer

usually much smaller than the variations of primary radiation. The njea-

surements by counters and ionization chambers make a comparison of the
variation of intensity of the. primary protons with the variation of the
intensity of the heavier primary nuclei possible. The variations have to
be determined in the various regions of the energy spectrum of cosmic
radiation. This is only possible on satellites with suitably seleot-ed
orbits. The measurements of the intensity above the polar regions are
of special interest.

the measurement data can be transmitted during the entire time of the
satellite's existence, The experimental material thus obtained on one

Measurements of Cosmic Radiation_W_*i~ii of an Artificial Earth Satellite,
This paper was first published in Doklady Akademii Nauk 'USSR Vol. 120,
Nr' 6, 1958) pp. 1231-1233. The paper presents prellmin ry results of
measurements of cosmic-ray intensity obt#ined with instruments installed
in Sputnik 11. The close agreement of dAta from two separate instruments
indicates the validity of these results. A brief description of the
instruments and their operational characteristic are given. Since
the ascending and decending segment of the orbit occurred at consider-
ably different altitudes, it was possible to determine the relative

variation of cosmic-ray intensity as a function of altitude for the same
geographic points. The intensity wea found to increase considerably between
225 and 700 km, the highest altitude achieved by the satellite. This vari-
ation is attributed to three causes: a) decreased screening by the earthj
b) reduction in the magnetic field of the earth permitting penetration of
lower-energy particles, and c) change in the albedo of cosmic radiation.

ABSTRACT: The results discussed in this paper were obtained by
equipment incorporated in the second earth satellite. In
order to be able to record the variations of the intensity of
the cosmic radiation in a reliable manner two similar countera
for charged particles (with a length of 100 mm and a diameter
of 18 mm) was mounted in the sputnik. Both devices contained
counters operating on the basis of semi-conductor triodes. The
power consumption of the whole apparatus was 0,15 Watts. The
batteries permitted continuous operation for 200 hours. The
relative increase of the intensity with altitude was com-
puted from the ratio of the intensity of cosmic radiation on the
"inverse loops" (passage from the North to the South, at an
Card 1/3 altitude of 350 - 700 km) and the intensity on the "direct loops"

Measurement of Cosmic Radiation by the Sputnik SOV/2o-12o-6-18/59
(passage from the South to the North at an altitude of 225 - 240
km) measured at the same geographical points. This variation
can be -in:d by at least three effects: 1) An increase of in-
tensity due to a reduction of the shielding by the earth. 2)
A reduction of the intensity by the weakening of the earth's
magnetic field 3) By a variation in the albedo of the cosmic
radiation. The dependence of the intensity upon the altitude
can be explained by the first two effects. From the data obtained
by the measurements of many loops the lines of equal intensity
of cosmic radiation (isocosmic lines) are obtained. Such iso-
cosmic linetj are presented for three different counting rates.
The experimental points above all fit upon the geographical
parallels. The line of the minimum intensity of cosmic radiation
(the "coomic equator") does not coincide with the geomagnetic
equator. According to the evidence obtained the intensity of the
cosmic radiation sometimes increased considerably. During this
the intensity fluctuated very much. There are 4 figures an4

ABSTRACT: The rocket launched on January 2, 1959 in the direction of the
moon bad apparat--;-q for recording cosmic- and terrestrial corpuscular
radiation on boazvl. By the latter the authors mean the flu:-es of
fast charged particles in grpatl altitudes, for which the tw-,estri.al
magnetic field is a o- -all-id "miagnetic trap7'. The particles -xerr-
recorded by 2 Geigez-uouriters and 2 s cinti, llation- counters. The
first apparatus, wita sointillation counter, was a conatruotilre
further-develop-mert of the device winich the authors had built into
the third Sov-iet SIfatnik. A cylindrical sodium-iodide crystal
served as a detector. The authors, above all, described the result:.,
obtaine3 by the preliminary evaluation of the data ascertained In
altitudes of from 8000 to 150000 km (from the center of the eart!).
