,ABSTRACT: The author considers the much-discussed question of
whether the continental glacier, during the maximum
advance of glaciation (Dnepr-Don), reached the region
of Llvov. The author confirms the first observations
of traces of fossil permafrost in the environs of
Llvov and thus mukes it possible to outline a belt
of frozen tundra, bordering the 'Russian glaciation
and occurring along the southwestern edge of the Rus-

On the Tectonic Features of the North-eastern Part SO'1/20-126-2-36/64
of the Upper Tisza Depression (Trans c arpstb1s)
The author describes the profile of the River Tereava and the
fractures occurring in the said syn- and anticline3. All the
described fractures date from the end of the Pliocene period.
On the authority of V. B. Porfirlyev, the brittle coal-veins
found in the fractures developed through the -melting of the
organic mass with the resulting further impregnation of these
fractures. At the end of the Pliocene and in the Pleistocene,
the northern$ north-eastern, And north-western parts of the
Vorkhno-Tiaasnakaya (Upper Tisxa ) depression raised. In the
south-west and western slope of the Vygorlat-Gutinskiy
volcanic range, however, de ressiona occurred. Here was a
quaternary sea-wator (Ref 45. There are 9 references, 6 of
which are Soviet.

TITLE The MTOTwution between Past Pions and Nuclei.
PERIODICAL Dokl.Akad Nauk 111,faeo.4,795-798 (1956)
Issued: ; / 19~7_
In the course of this work the results obtained by computing the nonelastic
scattering of negative 160 MeV-pionn by the nuclei of the photoemulsion are
compared with the experiment. On this occavion the assumption concerning in-
dividual meson-nucleon collisions within the nucleus is accepted an being
correct, which in also indicated by the experimental dqta available concerning
the nonelaotic scatterine of pions by nuclei.
Experimental data: The authors used the bundle of nogative plons with tile
energy E. . 188 + 6 MeV emerging from the chamber of the synchrocyclotron of
the Institute fo~ Nuclear Problems of the Academy of Science in 'the USSR. This
bunTrC-,_aTT_e_r-p-a-seTn_g _G_rou-Gh a- dWf1`-e-eT1-ng-a&Cnot and a collimator incided
upon an emulsion chamber consisting of layers of 395,,(-4- thickness. There are
30 of these layers. The stars found in the emulsion chamber were selected so
that the experimental results obtained relate to E - 160 MeV. Together, a to-
tal of 1105 act" of interaction between such negative pions and the nuclei of
the photoemulsion, among them 323 nonelastic acts of scattering of a charged
pion, were found. The acts of scattering of pions were identified by the de-
termination of grain density along the trace. For the 323 nonelastic acts of
scattering the energy- and angular distribution of the scattered nef;ative pions

Dokl.Akad.Nauk 111, fase-4,795-798 (1956) CARD 2 / 2 PA - 1935
were determined. For the further interpretation of the experimental material
obtained a graph shows the energy spectrum of the pions scattered in the angu-
lar range from 0 - 90 to 1800; this spectrum has the average energy of
64 + 3 MeV and the half width (30,9 + 3) Nev.
Gom;utation of the interaction betwe;n negative 160 Mev pions and the nuclei
of the photoemulsion was carried out on the assumption that mason-nucleon
collisions in the nucleus develop in a way similar to that of the free nucleons.
The results obtained on the basis of the scattering of pions by the nucleons
of the nucleus by the computation of the energy- and angular distributions of
meson-nucleon collisions within the nucleus do not depend on the particular
features of the cross section of the interaction between a pion and the nucleons
of the nucleus. Therefore the potential of interaction between the pion and the
nucleus can be evaluated with sufficient accuracy on the basis of the results
obtained by the aforementioned nonelastic scattering tests. The conditions
upon which such an evaluation is 'based are enumerated. For the average inter-
action potential of negative 160 MeV-pions the value V - Eexp - :Itheor ~
- (24 + 6) IdeV was found. This value agreca with the average potentials of
;he inteiaction between pions and nuclei which were obtained by experiments
concerning the elastic scattering of pions by nuclei.

ABSTRICT: This work oomp&ro3 the computation of the inelastic scattering
of negative pions of 160 NeV by the nuclei of photographic
emulsion with the experiment. Computation of the interaction
109tw*en fast pion@ and the nucleus, contrary to analogous com-
putations of the interaction of fast nucleons, offers the ad-
vantage that in this case the nucleon part of the inner
nuclear oasoade has not to be taken into account.

pion in the nucleus, the oaloulation of the scattering of
pious by the nucleons of a nucleus, the effects connected with
the modification of the potential on the occasion of the
passage of a pion through the boundary of a nucleus, the ab-

The good agreement of the theoretical with the experimental

TEXT: The asymmetries of the contours of the H0and H6 lines oVeerved
in hydrogen plasma when the density of the charged particles is
Nl~ 1016 cm-3 are a function of density. They manifest themselves in the
intensity being shifted toward the short-wave region, in a shift of the
intensity maximum relatively to the line center, and in a variation of
the interval between the maxima. Hence thq de'nsity of the charged
particles can be determined by comparing the contours lound experimentally
with the values calculated from a theory which explains these asymmetries,

Stark effect, the quadrupolo contribution to the interaction energy between
the atom and the ion is duly considered. The wave functions of the
Schroedinger equation in parabolic coordinates are given for this case in
first approximation. They lead to general expressions for the energy
splitting, intensity and probability for the position of the Stark com-
ponents. The numerical values for some transitions are given in a table.
For the H0 line, the theoretical and experimental values obtained for the
intensity variation in the maximum and for the shift.of t9e maximum
relative to the line center agree fairly well for N 10, - 1016cm
Whilat the calculated distances apart of the maxima as a function of N
agree with experiments, it in unlikely that useful values could be obtained
for the line width, owing to the rough assumptions that have to be made for
the electric field of the ions, and since the line broadening due to
electron impact is neglected. 'In order to improve the theory here
preaented, which includes no statement on the line center, the influence
of the electrons should be considered. There are 2 tables.

Mass-Flow Augmentation in Jet En6inoO (Cont.) SOI~,'3848
This paper presents a theoretical and experimental study
of the offects of addinft ~.-c pulsatin&~ Jeto.
It I P C`Oii~c. -i*.he addition of atmcapheric air to a
pulciating gas jet may lead to a considerable increase
in its impulse. The addition of supplementary air mass
is not only due to ejection, that is, the parallel addi-
tion of air into the driving jet which is associated with
mixing, but also to the interaction of separate masses
ofair added gradually. Two forms of this gradual addi-
tion are possible, namely gradual expulsion of additional
mass and gradual inflow of air behind the driving jet.
The largest increment in thrust (up to 120 percent of the
thrust of a single nozzle) was obtained in a compound jet
nozzle with an open shroud which includes the three-basic
forms of the process of mass addition (ejection, expulsion,
and gradup.1 inflow of uir behind the drivin-fr jot). The
gradual inflow is the basic process which produces a large
increment in thrust and determines the character of Its
variation as a function of the basic parameters of the
pulsating flow. The thrust increases obtained in the pro-
cess with gradual inflow were found to be close to the
corrcsponding calculated values based on the assumption
of no losses due to friction or vortex formation. This

result confirms that the process of gradual inflow Involves
small energy losses and has efficiencies of 75 percent and
more. The tests also showed that the thrust increases are
reduced as the cyclic frequency and the initial rate of pres-
sure drop are increased. For a given frequency the thrust
increment increases as the outflow from the central nozzle
becomes more unsteady. The experiments also showed that
the addition.of atmospheric air to the exhaust of a piston
engine may increase the exhaust thrust up to 70 percent.

ABSTRACT: A geometrical factor appreciably affecting the
chaxacteriaties of combustion chambers appears to be
the relative magnitude of the critical (throat) section
of the nozzle in relation to the cross section of t-'-e
chamber ioe. FKp/FK, where FxP - area of -the throat of
the nozzle, FK - cross section of tho combust-ion chambor.
An increase of the ratio above a certain val-.-,e leads to
substantial drop in pressure along the axis of tlae
chamber (Ref.1) and this results in the follo*elng:
1) supply of heat to the gas takes place with decivasing
thermal efficioncy; 2) residence time (the time Interval
during which ttLe molecules remain in the combl-,SAJ.Loa
chamber) decreases and in conzequence the ti-Pe available
Card 1/8 for the fuel to burn 1e shorter; 3) the rate of 'vs1ming

gas velocity. This paper gives the results of
theoretical investigations of the effect the releti-te
critical section of the nozzle has on the Of
liquid propellant rocket engines (LPa), taking into
account only two factors: thermal efficieLxy ar-E
residence time. Assume that it is possible to obtain in
a rocket engine consisting of a cylindrical combustion
chamber of a volume Up = const. and a nozzle with
sufficiently small thr-oat section (F /F < 1/4) (F~S.Ib)

a working process which is c-haracterffed 7 the total

is introduced, it
simply being a comparative factor between the constant
pressure chamber and an actual chamber where the constant
process is not achieved. Fis-5 shows this relation and it
is seen that the required volume of the non-coastant
pressure chamber increases directly with RO/Fk (0-9-
for Fkp/l?k = 1 the increase is 40%) but do nds very
little on the temperature. In practice it does not
always pay to increase the volume of the combustion
chamber as this results in increased weight of the
engine amd also in increased heat losses through the
larger area where the temperature is the highest.

For this reason the author examines next in Chapter 111
how the specific impulse varies with non-constancy of
pressure in the combustion chamber. The results are
presented in Fig.6 which shows the relation
Il~yd = P~yd - P�d f PIM for various 9k
Pyd Pyd Fk
where: Pyds P'yd are the specific impulses with constant
pressure chamber and non-constant pressure chamber
respectively and Tk is the completeness of the
combustion process. The figure shows that the larger
the ratio Fkp/Fk the larger the loss in specific impulse
