1202. Varitron Mass Sp ctrum by A. I. Alikhnnyan, V. M. Morozov and A, V.
61, 35-38 (1948) July I (In Russian)
Khrimiam Dok. Akad. Nail SSSR
In a previous paper (Doklady Akad Nauk SSSR 58 No- 7 (1947) the authora published
varitron masses obtained from deviatlons of cosmic ray trajectories in a magnetic
field. The ranges covered were from 1.2 to 5.6 cm Flb. In the present paper more
accurate mass values are given for the same range interval, as well as values
corresponding to a range exceeding 5.6 cm Pb. The numbersous maxima on the distri-
bution shows the minimum momentum of a particle with a given mass; the position
of th-A'o abrupt slope permits the determination of the particle's mass. An
important interpretation is given to the fact that the negative slope Of some
of the maxima is abrupt too. An uprer limit for the momentum can occur in
cases where a particle of a given mass is generated through disintegration of
~ heavier particle stopped in air; the outcome of such a disintegration of
~ particle, under the conditions obodrved, must be the formation of 2 particleR,

and varitrons by a neutral component of cosmic radiation. F. 739
The generation of charged particles in lead, was observed at an altitude of 3250 m.
over sea level. This generation wa!3 caused by the neutral component of cosmic
radiation. A magnetic analynis of the charged particles (originating in the lead) showed
that they are protons and varitrcns. The assumption is made that the protons appear
as a result of the exchange of the charge which a fast neutron experiences at interaction
with a nuclear particle. It is possible that the varitrons which were observed during
the experiment originate at this exchange.

JABSTRACT: The article describes a bubble chamber with an effective volume of 200
;liters made of nonmagnetic austenit-B lKhl8N9T steel and consisting of a permanent
outer -vessel and the working chambe;7 proper located int-iide it. The design of the
inner ,hamber, outer vessel, and e;q)ander is generally similar to that described
in an earlier article by A. V. Bog(naolov et al. The upper lid of the permanent
vessel has six windows for photography. Differential three-stage valves are used
!for increasing pressure and for dela,essurization in the chamber. The working
;space of the chanber is illuminated by eight out of sixteen IFK-120 flash bulbs
~Jllounted in pairs on a special panel; the lighting system design also permits
!the use of IFP-40OO bulbs. The photographing is done on two standard aerial
I
:photographic films, with a sensitivity of 1200 GOST [Gosudarstveennyy Obshchesoyuznyy

type ob3ectives. During operation of the chamber chromatic aberration was observedp
resulring in a ghost effect in the particle track image. This was eliminated by
photographing in monochromatic li~~it through an experizentally chosen orange light
filter. The chamber is heated by three 2-kw electric heaters, with one of the
i heaters set directly on the inner chamber. There are two versions of thermostat
I systen control. The first employs a standard contact thermometer mounted in the
chamb,,!r casing. The second version employs an electrocontact manoneter. The
article includes a block diagram of the chamber's control circuit. The chamber
was tested in operation with variotis working fluids: propane, a mixtw,e of Freon-12
and Freon-13, a propane-ethane mixture, and propane-Freon and propane-ethane-Freon
mixtizes. The chamber is at presert set up-in an MS-12 magnet in the path of a
bean, of negative pi-mesons, 4 Gev in energy, of the proton synchrotron oil ITEF
[Institut teoreticheskoy i eksper:~mentallnoy fiziki; Institute of Theoretical and
F_xperimental Physics]. The actuation cycle of the chamber is 4 seconds. The

ABSTRACT It is known that. in the case of some bacteria and fungi which have no
process of sexual, generation~there were produced during recent years,
hybrid forms which combined the characteristics of both initial forms.
The mechanism of this phenomenon has not been completely clarified and
apparently varios in individual cases. In the case of fungi it is based
on the phenomenon of heterokaryosis brought about by anastomoses. Accord-
ing to some authQra'the fusion of the germ tubes of the actinomycetes
takes place during spore germination~ According to other opinions the
problem of the generation process of the actinomycetes is not yet solved.
It was hoped, however, to obtain hybrid forms from these fungi. This
latter problem, beside,bbing of- theoretical interests would alsos
if solved, be oJ7 great -practical advantages namely in the selection of
producers of an,-,ibiotics originating from actinomyces. In the present
work the attempt was made to produce com~insd forms between two bioche-
mical mutants of Aciinomyces rimosua (producer of terramycin)e For this

of the fungus. Zle biochemical mutants were obtained by irradiation
with ultraviolet rays of a bactericidal lamp BUF_30, which emits 600/0
rays 2537 X of length* Test tubes with insufficient growth were used
for further cultivation by the addition of some drops of liquid maize-
-culture medium. Biochemically defective forms isolated in this manner
were then examined for amino acids and vitamins. Among them were forms
which needed vaxious vitamins and amino acids. The obtained biochemical
mdtants were sown by pairs.' On a culture medium of maize some peculiar
phenomena could at once be observed. Growth and sporulation along the
limit between the colonies of different mutants were much more intensive
than in the other parts of the colonies. The zones of this abundant
growth formed small mounds, the air- mycelium in them being of a different
color than that in the two colonfes of mutants, The tran3mission of those
resulted in poor growth and rough colonies. Mixed sowing of spores in
thick suspensions afforded colonies as described above. The nature of
the interaction is still obscure. Two explanations may be suggested:

10 A peculiar type of synchronism becomesevident on this occasion.
No new formations develop. This is indicated by the parallel growth
noticed in the case of actinomycetes. It is possible that bundles of
different hyphae develop in common culture of biochemical mutants.
The hyphae lying close to each other suppix each other with the lacking
foodstuffs. This leads to a more powerful common growth than in the
case of separate cultivation. 2.) Between 'the mycelia occurs the forma-
tion of heterokaryons which contain the nuclei of both mutant types.
Their interaction in the heterokaryon mycelium explains the more power-
ful development. In both cases the sowing must lead to the cleavage of
the initial tyl)e-:, as it actually happens. Future experiments will
show which'of the two explanations is true* The problem of hybrids of
ray fungi is by no means solvedt

ABSTRAM Swanson proved.in 1948 that the frequency of mutation of AsRer-

after the tre;-tntent of their spores with small doses of bis-B-
chlorethylmethylamine, if they are subsequently exposed to vio-
let rays, than by an exposure to ultra-violet rays solely. It
w4s therefore presumed that the environmental factors can produce
an effect upon the sanditiveness of the cell with respect to the
radiated energy, viz. thaythe frequency of mutation is not only
a function of the absorbed energy. This induced the authors to
study the effect of the combined action of ethylenimine- and

that the decay of spores as a consequence of their exposure to

previous tres.tment with ethylenimine - compared with their mort-
ality in case of an inverse sequence of the saidt factors. The

action, when ethylenimine was applied first, are given in table
2. This frequency rises rapidly in the case of the latter sequence
of treatments. The same results were obtained with Str. aureo
faciens. As to the mechanism of the rapid rise of the frequency
of mutations which were induced by ultra-violet rays, it may be
assumed that tl-,.e sansibilization of the cells ae:dnat ultra-violet
rays increascis under the effect of ethylenimine. By this, the
action of thci ultra-violet rays upon the nucleus is intensified.
It may also be presumed that these rays excite the molecule ethyl-

previous treatment of the conidia with an aqueous solution of
the nitrous yprite form, i.e. bis-g-chloro-ethyl-amine HC1

of the spore. It is known that this content determines the

ultraviolet iays alone (Ref 2). Ethylene imine (EI) shows in the
case of Streltomycea aureafaciens and S. griseue a similar,
though weaker effect (Ref 3). The authors investigated the
combined eff(,ct of EI and of the ultraviolet- as well as of the
X-rays upon the selection in order to increase the formation of
the antibiot-'.c in the case of the culture Nr 221 of Act.erythreUB.
The activity of the initial culture amounted to only 450-500
units. The oporea, sAepended in distilled water were stored
2j and 48 hours long in an EI-concentration of 1115000 at 3 and
5 and then ';reaied with a dose of ultraviolet rays
(250-2000 er,I/mm ) (lamp - Ref 4) or of X-rays 50-300 kr. The
activity of --.he control and of the chemically pre-treated cul-
ture was est.1mated by fermentation in a soybean medium. The
tables 1-,I show the results. (Table 3 - some new cultures).
The followin,g definite conclusions are drawn from the obtained
resultst 1) -lereditarily stable active variants could be obtained

A13STRACT: In 1952 Zinder and Ledoiberg (Tainder and Lederberg, 11of 6) for
the first timt observed the phenomenon of transduction in
Salmonella. It is based on the capability of phage to transfer
in some cases the individual properties of those bacteria on
which the reproduction of the phage has hitherto taken place.
Several authors have proved that on the occasion of the infection
with phage only desoxyribonucleic acid enters the bacteria cell
while the protein contained in the phage remains outside. In
this connection the authors wanted to investigate the change-
ability of Actinomycetes under the influence of actinophage. A
survey of publications on already known evidence is given (Refs
1-4)- On -table 2 data are given on the spontaneous frequency of
Card 1/3 mutations in the race H-6 of Actinomyces olivaceus-after a joint

breeding with aotinophage Nr 2671 and 8238. As can be seen from
it the frequency of mutations attains 97,2% under the influence
of the former, these mutants, however, are of another type than
those formed urder the action of phage Nr 1 and 2 (Tablesl and
2). The mutations formed under the influence of actinophage
Nr 8238 show a deviating frequency and deviating morphologic
characteristicti. Thus, it can be seen that the action of all
three actinopheges on the race H-6 is deeply specific. It can
be assumed that the phenomenon described above is based on a
certain similarity with the transduction in bacteria. In the
experiments described here no distinctive transfer of the culture
of the host on which the phage multiplied took place. Howi~er,
certain morphologic variabilities of different type were obtained
under the influence of variants of the same phage (Nr 1) which
was bred on different cultures of Actinomycetes. These changes
were not causeel by a damaging action of the actinophage. Some
groups of the changed colonies reproduced the mutants which form
under the influence of ultraviolet rays. It is possible that, if
actinophage is bred on a certain culture of Actinomycetes it may
Card 2/3 become the carrier of a certain genetic information. The latter

ABSTRACT: At the International Conference for the Peaceful Use of Atomic
Energy held'in Geneva in September 1958, the problems of
radiation genetics played an important part. Questions of
genetic consequences of radittion, the mode of action of
radiation and radiosensitivity, the protection from radiation,
the use of tritium in scientific resear'ch, and the improvement
of oultures and genetics were discussed. N. P. Dubinin outlined
-the basic trends of laboratory work for radiation genetics at
the Institut biofiziki Akademii nauk SSSR (Institute of Bio-
physics, Academy of Sciences, USSR). S.iil. Alikhanyan report-
ed on succesnes in the field of radiation selection of anti-
biotics producers (mushrooms and actinomycetaceae) in the USSR.
The authors of this article state that Soviet scientists are
working in a number of directions on the same problems as
