PERIODICAL: Nauka i zhiznl, 1959, Nr ?, pp 2-8 (Usel"N

ABSTRACT: The article consists of 6 separate interviews with the
most prominent scientists of 'Uzbekistan, condacted in
April 1959. The 1st inte:rview was with. Khasyl Fazylovich
Fazylov, Academician and S)e-cretary of the Akademiya nauk
'Uzbekskoy SSR (AS of the Uzbekskaya &JR), and dealt with
'both research and research institutions in that republic.
During the last- 3 years, 9 new research -institutes were
established,, including the Institut yadernoy fiziki
'Jnstitute of Nuclear Physics). In addition to this, a
new atomic reactor, the first to be installed in the
eastern part of the USSR, will go into service by the
end of 1959. A new computing center equipped witha rapid--
action, "Ural "-type computer is also in operation.The

-total of scientific workers working at1he "institutions
of the Academy of Sciences is 1,800 of whou nearly 30;6
are doctors and candidate.9 of sciences. In addition to
thist 4.30 post-graduates a:ve being trained there. Kh.M.
Abdullayev, President of the Academy, was etwarded a
Lenin prize for a new, ingenious method of conducting
geological studies relevant to prospecting. By using
it, 2 new, large ore deposits of great impcrtance were
discovered. The academy is also noted for.its research
in the field of muthematical statistics and theory of
robability, Founded by Academician V.I. Romanovskiy
'deceased), this scidntific; sector is being successfully
t
developed by Academician T.A. Sarymsakov and Correspon-
ding Member S.Kh. Sirazhdinov, both-of -the above acade-
my. The Chirchikskiy elekl;r,okh imko mbinat 'C"hirchik Elec-
tivo-Chemical Combine) and the Insti-but khimLi (Institute
of Chemistry) have jointly developed a new :?rocess to

p.roduce non-caking fertilizers. .-Inother team of
scientists worked out a rational method to make sulphate
-:r-esistant llgliyezh"-Port.LzLnd cement. The Institut khimii
rastitelInykh veshchestv (Institute of the Chemistry of
Plant Substances) found some 30 new alkaloids, and de-
veloped a new method to e-ctract lemon and apple acids
from cotton The followinG 3 in:3titute3, In-
stituty enerGetiki i avtomatiki, of geologii, i
Sredneaziatskiy politekhnicheskiy institut (the Institutes
of* Power and Automation, of Geology, and the Central-
Asian Polytechnical, Inst-"tute) are worhing on blue-prints
to build a large plant for the production of high-vol-
ta,Ge, porcelain insulators. The Fiziko-telchnicheskiy
institut (Institute of Pkirsics and Technolo3y) developed
new hig,h-voltage, selenic rectifiers able to withstand
frequent overloads, which went into pro&:uction at sever-
al plants a short time ago. In spite of its fast--rowing

industry, the chief production item of the Uzbekskaya
SSR will still be cotton. Tae present production of
cotton is 3,000,000 tons peV year, and is scheduled to
reach as much as 3,800,000 -tons by 10,,65. The republic is
also rich in non-ferrous and rare metals. By 1965, it
will be one of the top producers of those metals in the
US"SIR. Its output of non-forrous metal-, is to Grow by
6.1. times. According to the Seven-Year Plan, the fol-
Lowing 3 institutes have i.lready been established: The
nauchno-issledovatellskiye instituty khAmii polimerov,
mekhaniki., Geolo0ii i razrabotki neftyanykh i gazovykh
mestorozlideniy (Scientific Research Institutes of the
Chemistry of Polymers, of Mechanics, of Geology and
Development of Oil and Gas Deposits). Infature, the
followine; 8 new institutes mtll be added: instituty

AS of the Uzbekskaya SSR. It dealt with the development
of cotton harvesters* Profossor R,StatE!d that the de-
velo I
pment of a new, verti(;a'-type spindle harvester is
nearly completed. Pneumal,ic. harvesters,'up to now under
development, belong to the SO called llblowing"-type units
and are unique. Suction hai--vesters are also under de-
velo,ment. Plans are under way to build a combined
.P
pneuinatic-and-spi-ndle harveister. The newly-established
Institute of Mechanics of the AS is in charge of the
above developments. The third interview was conducted
with Saadat- Sadykovich Sadyhov, C/orrespondin(r, 1"Leeber of
the AS Uzbekskaya SSR, and Director of the Institut gene-
tiki i fiziologii rasteniy (Institute of Genetics and
Physiology of Plants) of thE! AS. It dealt with new, hirrh-
yield cotton 0seeds, which C,:Ln Grow at teapercitures as
low aS 14-15 , whereas tropical cotton develops poorly
even at 18-20 C. The above institute developed the

following new cotton seeds: "AN-202", 1111111-2CW9 "AN-209tri
and 11.0-210". They all have large bolls and do not re-
quire hiE;h temperatures combined with short sunshine
periods (up to 12 hrs per illy) u*ntil they roach normal
height, as do late and medium-late cotton seeds. The
fourth interview was conducted with Gani Arifkhanovich
Afavlyanov, Corresponding Member of the AS Uzbekskaya
SSR and Director of the -Institut geologii (Institute of
Geology) of the AS. It dealt with research of underground
water., According to the latest calculations, underground
water can be utilized for Irrigation of inore than.10,000
hectares of lands in the F(.:-re~,ana valley and 50-75,obo
hectares in the north-east(irn part of the Golodnaya steppe.
Great, untapped reserves ol underground Nvater are located
beneath the Samarkand hollow, the Bukhara and Karakul$
oases, in the Surkhan-Darlya and Kashka-Darlya valleys,

1958 to 3POO,000 tons by 11)65, that of Gas from 126,000,00D
cu m in 1958 to 300,,000,000 cu m by the end of 1959. By
19659 189000,000,000 cu m of gas ~,,rill haire been produced,
which -rqeans that Uzbekistan will no longer need the more
than 4,000,000 tons of coal per year imported from the
Donbass. Yuzbass,, and Karaganda. The sixth and last inter-
view was cordactedaith Ubaydulla Israilov-'-ch Karimov,

separate works in Uzbek, Persian, Arabic, Turkish,
and other languages. The institute is gointr to publish
the fifth and last volume of the world-famous medical
handbook, the "Carion of M.adical Science" by Aviceima

TEXT3 The authors of the present paper wanted to develop a
potentios-.at
that would be easy to manufacture and convenient in use. The
followin,,
facilities were utilized: potentiometer Tr--4 (P-4); a-c
amplifier ~')L109
(EU-109), and the reversing motor P~.-09 (RD-09). The
ele,t.ronj.c
potentiometer 34M (EPP) served for. the automatic recording of
the current
flowing through the cell. The electrolyti(: cell 1 (Fig. 1) is
fed with
direct current of the controllable current source 2. The
potential of the
working electrode is given by potentiometer IN -4 (P-4). 11' it
deviates
from the given value, the out-of-balance sj.,,nal appears at the
pot-~ntiomeWr
output, and, after having been amplified by electronic
amp:iifier 5, starts
the reversing motor which is mechanically i.--onnected to the
con;rollable
current source 2. The current strength of the cell is meat3ured
by
milliammeter M-62 (M-82) or recorded by po-,entiometer 5. In
this case the

scale of potentiometer 5 is varied by means of resistance box
7. The
switching over from milliammeter to potentiometer takes place
by means Of
commutating switch 6, while the operating current of P-4
potentiometer is
regulated manually. Whenever, with a low current strength in
the circuit,
it was necessary to keep the potential accurately constant, the
cell was
fed by a 12-v battery accumulator over a voltage divider. The
latter
consisted of two double alternating resistors of the type MP
(VZR) and
interposed helical potentiometer. For a resistance of
the,voltage divider
of 1.045 ohms and a cell current < 300 ma, reguiation was
accurate to
! 0r05 mv- Moreover, the s~Ttem included a transformer-rectifier
arrangement consisting of ~ P (LATR) arranged in bridge
connection, step-
down transformer and rectifier. The current was regulated by
the reversing
motor-which was connected to the LATR axis. For
