ABSTRACT: It was observed that the bays of the magnetic field have.
regular diurnal variations. During 1954-56 in Murmansk the
positive bays, which are more frequent in winter, occurred
,mainly in the second half of the day while the negative ones,
which are more frequent in summer, were mostly observed in
the first half of-the day (Tables 1, 2 and 3). The currents
causing the bay disturbances, change their direction from
W-E (Fig 1. curve 1 - positive bays) to E-W (Fig 1, curve 2.

were accompanied by the abnormal variations of the ionosphere.

cases, a complete fade out of the radio wave took place.
With an increase of the magnetic activity the character of
the ionospheric variations affected by the bay disturbances,
changed, i,e, the number of occurrences of the ES and the
full fade-out decreased together with an increase of the
anomalies in the region F 2 (Table 4). Fig 4 shows -the

TEXT: This paper gives preliminary research results on disturbances of
the ionosphere in high latitudes and their spatial distribution according
to data obtained in the Geophysical Year. In years of low solar activity,
foF2 in high latitudes is below 1 - 1-5 Me/sec during the morning and
evening hours of winter months with quiet ionosphere. Broadcasting on one
frequency over 24 hr is possible during the polar day, during the polar,
night, maximum foF2 is after midday. Considerable absorption of waves
frequently occurs during disturbancesi and the E layer has higher cutoff
frequencies, To take the fluctuations of f . into account, the degree of
min
absorption is expressed by the equation af min = fmin -(f midmedian'

Increased absorption is assumed when 4f min exceeds 4VIc. f131s ~14 Me/see
corresponds to a disturbed ionosphere. The most.important characteristics
of a disturbed ionosphere in high latitudes are total or increased absorp-
tion, increase in the cutoff frequency fEs over 4 Mc/sec, 2e. variation of
foP2, and occurrence of E~s. According to observations by the Wirmanskaya
Stantsiya (Murmansk Station), total absorption usually occurs in the
morning hours, increased absorption at noon, and fEs > 4 Mc/sec toward
midnight. The daily variation of positive and negative &foF2 > 20 ~-
during 24 hours is not so distinct, most frequently they occur in the
evening hours. North of the zone of polar lights, the frequency -of Es has
two maxima; in the zone of polar lights it has one maximum at midnight.
The duration of "undisturbed periods" is shorter in high than in low
latitudes. Disturbancesusually set in between 16 and,24 hr. Throughout
the year, total absorption usually-occurs during equinoxes, increased ab-
sorption occurs again in summer; by night, Es usuaUy occurs in wiAter, by
daylight in summer, and most foF2 anomalies occur in winter. Also in high
latitudes, disturbances of the ionosphere tend to recur in a 27-day cycle.

were set up, and the data obt ained for July, September, and December 1957
were analyzed in a-widespread network of research stations. According to
the'charts of total absorption for 0, 6, 12 and 16 hr world time for
September 1957 (where most disturbances were recorded), the zone of total
absorption reaches from the pole to 4 = 500 north latitude on the eastern
hemisphere, and 600 north lat-itude on the western hemisphere. On the
eastern hemisphere, total absorption occurs much more frequently, and is
strongest at 6 and 18 hr world time on the morning side of the earth, in
the zone of polar lights. On all charts, the region of the highest
frequency of total absorption is asymmetrical with respect'-to tho poles.
Besides, increased fading in high altitudes occurs when A f min reaches
100 - 20W6, and when its region is asymmetrically distributed over the
two hemispheres and larger in the eastern hemisphere. Disturbances of
fEs > 4 Me/see in the analyzed period occurred more frequently,in the
western hemisphere, mostly in Canada. It is difficult to predict
disturbances for high latitudes, since the extent of absorption and
cutoff frequencies of the Es layer have also to be forec,,~st besides foF2.

the energy of short-wave solar radiation and does not substantially change the

ABSTRACT: Ionospheric perturbations are associated with solar corpuscular streams
.and the magnetosphere.\'YAn increased disturbance in the F2 layer at high latitudes
is connected with additional -ionization and structural disruptions of the lower
ionosphere. Data obtained from 60 ionospheric stations during the IG~~Zere used
in analy'sis of the spatial distribution of anomalous absorption in the Northern
and Southern Hemispheres. Absorption maps have been drawn and compared itith solar
processes, ionospheric disturbances, and perturbations in the geomagnetic field.
Anomalous absorption begins several hours-after a type-IV radio burst and covers
the polar cap and the auroral zone. During weak absorption, preeminent "Shock
zonesil and quasi-spiral regions are formed allowing direct entry of high-energy
solar corpuscles. A corpuscular stream model with a forceless magnetic field vas
used for ionospheric disturbances. - A forceless magnetic field is EL necessary

condition for macroscoDic motion If the solar plasma in the chromosphereand corona
is compressible. Using this model, the appearance of solar low-energy cosmic rays
is possible with the plasma cloud in which the burst and magnetic field were generate
retaining injected protons. The geomagnetic disturbance is a consequence of the
interaction of the magnetic field of the corpuscular stream with the magnetosphere.
This approach to the problem does not require a solar plasma with a frozen magnetic
field. Analysis of synoptic maps of the deviation distribution of critical frequen-
cies in the F2 layer from the median value demonstrated the existence of regions with
increased and decreased frequencies. Maximum negative deviations occurred inthe
geomagnetic latitudinal belt of 40-750 and coincided with the beginning of magnetic
storms. Negative deviations were located in regions of magnetic anomalies. Positive
deviations of critical frequency occur during week geomagnetic disturbances and depend
-on the season. They appear in regions of magnetic anomalies. Variations of critical
.frequency in the F2 layer increase with the geomagnetic latitude, and they attain
maximum value in the aur6ral zone. Orig. art. has: h figures. CEG]

PERIODICAL: Doklady AN SSSR9 1957s Vol. 117, Nr 5, pp- 91T-92o (USSR)*
ABSTRACT: In a former paper (reference.1) the author found the ineffectiveness
of the subcutaneous introduction of 2 and 5 mg vitamim B3L 11 - 13'
days long with respect to the conditioned-reflectory activity in dogs.
In contrast to this, doses of lo and 2o mg 2o days long led to the
alteration of the functional state of the great hemispheres. This was
expressed in the weakening of the conditioned-reflectory reactionsj
their instability, in the disturbance of the proportion of forcea
(11 silovy7e,otnosheniyall), etc. Feeding of 50 and l8o aig vitamin B
lo days long was ineffective. In present paper the influence of stronS
vitamin B1 doses should be observed, especially on tile "super limit
inhibition" ("zapredeltnoye, tormozheniye") which was effected by
superstrong (Wsverkhsil'nyyf') conditioned stimulus. The conditioned

RBSTRACT: Thic is a book review. The book deals with linear electric
circuit diagrams with constant parameters. The book is divided
into three partst 1) Theory of' multipole circuit diagrams;
2) application of the general theory to the analysis of eleo-
tr_Jc circuit diagrams;.3) comparison of various methods for
the analysis of electric circuit diagrams. The author presents
a inethod of setting up equations for multipole circuit dia-_
grains. However, he does not give even one example that Laight
confirm the usefulness of his method. It is shown here that tho
well-known method of equivalent -circuit diagrams should be
preferred. The book is intended especially for persons dealing
with the theory of electric circuits. Some parts are diffi-
cult to read because the author employs rare1y used t erais
and expressions without explanation. There are 3 reference, 2

ABSTRACT: According to the most complete classification of multipoles
as given by E. V. Zelyakh (Ref 1) a 2n - pole is described
as being a multipole having n pairs of poles, the sum of the
current intensities in each pair being zero. A taultipole can
be regarded as a 2n - pole, in two cases: (1) when the
characteristics of the outer (with respect to the multipole)
circuit diagram ensure the sum of the current intensities to
equal zero, in each pair, and (2) when this is caus6d by the
properties of a multipole independent of the character of
theouter (with respect to the multipole) circuit diagram.
The first case is simpler. The second case only occurs with
Card 1/2 remarkable properties of the multipole. This cane is dealt

2n Poles SOV/161-58-2-1/30
with here. The conditions the.parameters of the multipole
have to satisfy if it-is a 2n - pole are as certained. Various
equivalent diagrams are investigated. All investigations are
carried out with respect to a multipole with three pairs of
poles. The results obtained may be extended to-multipoles
with any number of pairs of poles. There are 5 figures and
5 references, 2 of which are Soviet.

changes observed are connected with one of the following phenomena: The formation of a
i second phase" (the composition of which cannot be determined by the x-ray data obtained
for compounds of this system) or the modified transformation ofJ3-spodumene froin the
low-temperature form, stable in a temperature range of 700-800C to a high-tomporature
form, stable at temperatures higher than 900C. The formation of a second phase was ob-
iserved in all cases with oxide ratios between 1:1:4 and 1:1:10. If the line of the "second
phase" was eliminated, the x-ray diagrams of the compounds with oxide ratios from 1: 1:2
to 1:1:10 were very similar and differed only by a shift of the lines toward greater values
of 9 during the transition from the compound 1:1:2 to the compound 1:1:10. This offect
is probably connected with the formation of a wide range of solid solutions, includling.8-
eucryptite, 3-spodumene and petallte. However, both hypotheses can be verified only
by the preparation of monocrystals of,8--spodumene. Orig. art. has: 3 figures.

TITLE: Precision Measure-mant of Unit Cell Parameters With a

PERIODICAL: Kristallografiya, 1959, Vol 4, Nr 3. pp 372-381 (USSR)
ABSTRACT: It is recommended that the positions of diffractlon pealcs
should be measured from the positions of their cantree of
. gravity. A method of finding such positions with a
diffractoineter.is described. Here, wavelengths, not of
the emission intensity maxima but of the centres of
gravity of the spectral lines must be used. The corrections
for the Lorentz, polarisation and angular dispersion
factors are examined. A focusing monochromator was fitted
-to the URS-501 diffractometer which enabled it to record
up to 24J = 1680 and had an inappreciable vc;rtical -
divergence. As an wzample, the parameter of the unit
cell of tungsten was found, using CuKP radiation with
this tochniqxio. At 2-5 C it wan found to bo
