ABSTRACT-.. Alarge 12 Yn2)- scintillation detector is described which operates only with
reflected light. The most probable pulse amplitude measured at the anode of the photoi,
electric multiplier is established when single cosmic ray particles pass through the
scintillator as well as the variation in this amplitude as a function of the locatian
where cosmic ray mesons pass througb the scintillator. The scintillator detector con-
isists of the following elements; 1) scintillator with dimensions 50 x 50 x 5 cm3.1
12) FEU-24 photoelectric multiplier; 3) optical waveguide covered with white enamel;
A) opaque baffles; 5) FEU-3B photoelectric multiplier; 6) 8 units of plastic scintill-
latcrrs; 7) FZU-35 photoelectric multiplier; 8) plastic scintillator with an area of
a cm2; 9) lead shielding. Differential pulse amplitude spectra taken from the anode

ABSTRACT- hi order to investigate the problem of'the rate-at which a
substance distributes itself uniformly in a slag during open-
hearth smelting, a radioactive isotope, Ca45, encased in an
ampoule, was introduced into the slag through the central open-
ing of the furnace; slag samples were withdrawn through the
other openings. The intensity of radioactivity was measured
with a BFL-Z5 counter. The counting rate was determined by
the thick-lajer method, a procedure which eliminated the need
for weighing operations. The accuracy of the radiometnc
measurements constituted 55o including statistical errors

measurement, The rate of distribution of a small quantity of an additive is
smaller in slag than in metal; 30-35 minutes are required for leveling off of
the tracer in the Case of slag, and 8-15 minutes in the case of r-netal, de-
spite -the fact that the volume of slag is considerably smaller. Rates of
turbulent diffusion of Ga in the slag amount to 50-100 cmZ/sec and are
smaller by one order than the corresponding values of radioactive Co in
steel; in this connection, the author comments on an analogous difference
between the kinematic viscosity of steel and that of basic open-hearth slags.
The distribution of radioactive Ca in the slag is strongly affected by the
aerodynamic pressure- of the. flame.

ACCESSION NR:
Vostok Ul'and Yostok W., as a biological sensor. The advzntages of lysogenic
bacteria as biological :sensors stem not only from their extreme scnaitivity
to Various typesof radiation, but also fro m the fact that induced changes are
directly proportional to the dose of irradiation. 'In addition. 'E. coli was sub-
jected to the combined effocts of radiation and vibration in ground experiments.
Vibration was produced by means of a vibrator -with frequencies of 35, 70, and
700 cpsj an a;nplltuda ranging from 0. 4 to 0. 005 mm with a load equal to 10 g,
for parlods of 16, 30, and. 60 min, CoGIO in doses of 100 r at a rate of 21 r
Or nin served as a source of radiation, Lysogenic bacteria carried on space-
ships Vostok In and Vosto)t IV revealed induction of genetic changes produced
by space-I'light factors whi -ch was indicated by a significant increase in the
d ced effect was more pronounced on
number of.phage particles., .17he In , U
Vostok 111 than on Vostok IV. Forty-eight hours after its return to earth, the
bacteria c,3rried by Vostok. III had produced 4. 6 times as rnany phage particles
as controls which had -remained an earth. Ground experiments with vibration
indicate that the combined Vibration and gamma irradiation, followed by a
second exposure to vibration, , double the biological effectiveness of gan=s rays.

ABSTRACT: The object of the present work was an-experimental study
of the.noise produced in a channel which has recesses in
its walls. This case appears to be intermediate between a
free flow in an infinite atmosphere and a channel with
rigid walls. The expeximental set up is shown in Fig.l.
The air flow was produced by an apparatus described prev-
iously in (Ref.2). The size of the recesses could be varied
and the mean sDeed of,the current was 10-35 m/sec. In Fig.2
the dependence of noise on the speed of the current in the
channel having a height of 100 mm, and recesses 300 mm deep
x 100 mm. wide-is given. When the recesses are excluded
(channel with smooth walls) the variation of the level of
sonic pressure is prc3portional to the Gth power of the speed
of flow. This picturel however, is radically changed in

ABSTRACT: Noise and vibrations caused by fluid flow in-a centrifpgal pump can r2ach
.a high level and cause an adverse effect on normal pump operatioi. To determine the
physical naturie of these processes and their relationship to pump parmeters, e.g
-flow. and diame a
-rate--cavitation, rpm ter,.experiments were conducted using a speci
t *ily
designed.test-stand in which the effects.of noise and vibrations of the drive,
bearings, and the shaft werelell-minated. The obtained results show that when a pr p
opeTates.at close to maximum efficiency, the noise and vibration levels are minim. j "_'
At otbertban optimal pump operating regimes, the adverse vortex formation processes
intensify; at large flow rates, cavitation takes place and at small flow rates, the
flow in the pump impeller channels becomes nonuniform. This results in a sharp IncTense
in the noise and vibration levels. The obtained test resultB..can be used to deter-
mine the level of,noive and vibrations in geenetrically similar pumps made of t

the minimum -oulse duration is determined by -C min =1.5/,,!~f, where

solute error-in measurement of the non-electrical quantity; this
means that-the change in value of this quantity between two cor-se-

The maximum sensitivity of the pulse bridge is 1000 times Ereater
than that of d.c. or a.c. brid.ges. It produces a powerful output
signal with low power dissipation in the bridge arms. The use of
pulse voltage supply makes it possible to increase the interference
killing properties in comparison with the detectors used in other
Uypes. This results in a greater detector sensit%vity and makes tne
balancing much more accurate. A blocking-oscillator is surgested as
the supply source* The author acknowledges the help of NI.P. Voll-

Iri.this article, the author criticizes certain writers who hp-vc recommended
the "truncated" bass as the fundamental connection arrangement for phototransistors, and
advises against using phototransistors with a "truncated" base in photorelay circuits de-
signed to operate under heavy industrial loads. It is shown in the paper that phototran6iritor
connection with the "truncated" base arrangement is not acceptable in practice, primarily
because of the extremely low operational reliability of the tranBistor using this type of in-
ternal connection. BasIng his discussion on the Soviet phototransistor type F TG- 1, the
author shows that even ifthis trawlBtor is used under entirely realistic conditions, the

TR&NSLATION: Operating conditions of a composite semiconductor triode (ST) in the
switching mode are analyzed. The saturation state in both triode components are
ed only When the collectors are separated by an appropriate resistor. Statistical
c.3haracteristics of tbe composite triode are established by applying the Ebers-Mol.1
equivalence scheme. Exprerssions for current in the cut-off mode, ciiplification in the
active mode, and voltages in the saturation state, are derived by a generalized con-

dark-orange color. The intensity of the color fluctuated.
When it increased, it almost reached the zenith. On the
horizon a not very broad line of alto-stratus clovdB w S
seen. The aurora borealis was observed on September 3N,
1947, between 8 p.n. and 11 D.m. as well.

TITLE: Distribution of,Larch Between the Pechora River and

ABSTRACT.: Even though many scientists had been accumulating
extensive data-on.the distribution of the larch
throughoutIthe USSR and in the Pechora River region
P
for the past twenty years, the distribution of this
tree between the Pechora and the Ural remained ob-
scure.- In.the summer of 1946 the author succeeded in
~.visiting-.the basins of the Shchugur, Podcherem, and
-Vuktyl.Rivers, and that part of the Ural Mountains

Distribution of Larch (Cont.)
which lies east of the headwaters of. the Shchugur and Podcherem
Rivers. Here,he collected interesting botanical and geographical
-data on larch distribution. His work includes a map containing full
recent information on the larch locations along the right bank of
..the Pechora River, in.1the-region between the Pechora and the Ural,
and also along the Ural. Between the Pechora and the Ural the larch
is found in two areas which:never merge within the for6st zone
(South of 670 northern latitude). These are the Pechora and the
Ural areas. The author describes in detail locations of larch along
the right bank of the Pechora River and in the Ural fore-mountain
district,and points out that it is still not clear whether the
Pechora-Usa'and thehighland larch.area-extensions join each other
in the Upper Usa region. This has probably not been shown by the
observations. Thus a substantial part of the northern Ural Range
(approximately Afrom 630 301 northern latitude to 610 101 northern
latitude) has no larches., but the headwaters of the Kochem and
Gudyr-Vuktyl Rivers still remain to be investigated. The distri-

Distribution of Larch (Cont.)
-,butionlof-larch in the dornyy Ural extension of its area has been
described in detail. The~author'reviews the theories proposed by
various scienti'sts, concerning the ways along which the larch has
entered the northern,European USSR.. and.the origin of its habitats
in mountains andplainse He advan.ces his own theory as to how the
larch came to occupy the extreme northeastern section of the Euro-
pean USSR. He believes that the larch penetrated the northern
European USSR comparatively recently (in the Holocene), when the
area was covered by a glacier. The larch then spread over western
Siberia, reaching 670 to-680 northern latitude in the sub-boreal
phase of the Holocene. From here it moved across the Urals and
spread further in three directions: a) west along the southern edge
of the Bollshe2emllskaya tundra; b) southwest along the Usa River,
whence it reached the Pechora River and made its way north and south
along the river valley; c) due south along the Ural Mountains to
630 northern latitude. The Ural extensions of its habitat, which
lie south of 610 northern-latitude, are doubtlessly'related to its
