TEXT: The central problem of the qualitative analysis of
differential equations is the analysis in the neighborhood of a
periodic solution or in the neighborhood of a"singular point. Aftet
reviewing the investigations of A. Poincare, A.M. Lyapunoy, 1. Ran-
dikson and G.D. Sirkoff, the author points out-that the second meth-i
od of L.Yapunov may be generalized. The opinion of N.G. Chetayevit
K.P. Persidskiy and N.D. Hdiseyev that the topological map of the
distribution of integral curves can be investigated in the region
where a positive-definite Lyapunov function existst was confirmed
by N.N. Krasovakiy whose theorem is higrhly'praised by the author,

TITLE., Fff~-_ering in Time-Variable RMC Circuits
PERIODICAL: Slaboproudy' obzor, 1960, Vol 21, No 7, pp 398-402
ABSTRACT: The author deals with optimum filtering of useful signals
of the g(t) = a tk type in filters composed of variable
resistors and Axed capacitors. The possibility of
realizing filtev,'~or optimum filtration, i.e. minimum
noise valu:_3n_thR filter output at the required moment
if the useful signal is constant and the noise on the
filter input is stationary, is shown for the case that VK
its spectral defigity can be expressed by a fraction of the
polynomials in w and the denominator polynomial is higher
by one degree than the numerator polynomial. For filtering
useful siqals varying in time according to the relation
:(t)C= a~t the useful signal is at first transformed into
0. . a gnal by means of differentiators:and is then
filtered by a system of R(t)C filters. The solution of
the time-dependent change of the R(OC values does not
Card.1/2 depend either on the value of the useful signal or on the

value of noise. However, it does depend on the noise
parameters (autocorrelatIon function, spectrum density)
as well as on the duration of the filtering to be carried
out. The author further points out that the use of
differentiation at the inputs to the filters may cause
a certain theoretical difficulty. The differentiator
outputs could be easily blocked by noise which can
increase very rapidly with successive differentiation. V'r
However, actual differentiators containing D.C.amplifiers
are limited by parasitic capacitance which introduces
amall integrating time constants. These limit the
magnitude of noise at the differentiator output. Therefore,
the theoretical assumptions are only distorted for very
short time Intervals at the beginning of the filtering
time and have negligible influence on the result of the
solution.

TITLE: We Continue the Discussion on Seminar Methods
(Prodolzhayem razgovor 0 metodike seminara)
PERIODICAL: Vestnik vysshey shkoly, 1959, Ur 3, PP 34-38 (USSR)
ABSTRACT: Instructors have a different point of view on the
question: what are we to understand by the "creative
character" of a seminar? The general opinion, shared
by A.V. Netsenko and L.L. Ellyashov, instructors of
the Leningradskiy politekhnicheskiy institut (Lenin-
grad Polytechnical Institute) Z-Ref 27t is that the
main thing in a creative seminar is the lively, active
discussion of the theme. This view seems to be some-
what one-sided. The concept of a creative character
of a seminar embraces, in the author's opinion, se-
veral substantial elements, such as the form, the
students' activity, interestoin the discussion, high
scientific level, ideological trend, and the educa-
Card 1/3 tional influence. The author examines each of these

SOY/3-59-3-17/48
elements. The creative character of a seminar also
depends on whether the students' interest is concen-
trated on disclosing the scientific fundamentals of
the course, and the ideological sense of the studied
problems. The most important task of a seminar is
to instill Communist ethics and culture in the stu-
dents. An important condition is that the students
be properly prepared for the seminar. This depends
on a number of circumstances, but primarily on the
quality of the students' independent work. Much im-
portance is also attached to the plan of the se-
minar, which should be drawn up with thought and not
by one person only. The purpose of the plan is to
he,lp students in their independent work, and praqtice
has shown that an excessive number of questions
raised distracts the attention. The author disagrees
with Docent G.A. Malyy who does not consider it
Card 2/3 justified to compose the concluding remarks prior to

the seminar. That part of the remarks which is de-
termined by the character of the theme is at any rate
prepared beforehand. There are3 Soviet references.

TITLE: Extraction Properties of Di-isoamyl Esther of Methyl Phosphoric
Acid
PERIODICAL: Atomnaya energlya, 19591 Vol 7, Nr 3, pp 236-243 (USSR)
ABSTRACT: By hithertol known methoda the distribution coefficients af
WO 3 and uranyl nitrate in solutions of nitric acid and solutions
of DARPA (di-isoamyl esther of methyl-phouphoric aoid) in
petroleum were determined du the basis cf he DARPA-c-ontent
in the extractive and on the U02(NO3)2 and HN03-content in the
aqueous.phase. It could be shown that, especially in the
aqueous phase, small uranium-concentrations can be extraoted
with DARPA considerably better than with TBP (tributy! phosphacte).
The extraction mechanism develops according to the equation
H+ + N03 + DAJMA;;-,= UNP)DAMPA (1)
where HNO3DARPA is a compound extracted entirely from the o--garLc
phase. The rules governing the extraction of uranium from

value). The equilibrium constant of reaction T2) with a 20%
DAMPA-solution, however, is 2540-+ 200. The values determined
during the various'experimental 97tages are represented partly

TITLE: Extraction of Uranium(VI) by Means of Tri-n-octylamine
From Nitric Solutions
PERIODICAL: Zhurnal neorganicheskoy khimii, 1960, Vol. 5, No- 10,
pp. 2354-2362
TEXT. The authors wanted to make a detailed study of the extraction of
U(VI) by means of solutions of tri-n-octylamine (TOA) in o-xylene and
carbon tetrachloride. In an earlier paper (Ref. 10), it had been found
that in the presence of free nitric acid the entire TOA is contained in
the organic phase as TOA-HNO3. Therefore, the authors write down the
following equation for the extraction of uranium:
TOA.HNO + UO 2+ + 2NO- - (TOA.H)UO (NO (1). The
3 org 2 aqu 3 aqu 2 3 3 org
dependence of the distribution coefficients on the concentration of free
TOA.HN03 in the organic phase was studied at concentrations of 4.3 and

according to Ref. 10, the concentration of TOA-HU03 varies in the organic
phase as a result of the reaction

%qu + N03 aqu 3 org - M103
account. By using o-xylene as solvent the constant X3 of this reaction
was found to be 0-13. Table I gives the values for the distribution
coefficient af Fig. I shows that with K 0-13 the distribution
coefficient a increases linearly with Ue'concentration of TOA HN03. At
403 mole/1 HNO 3 aq, and 0-470 mole/1 TOA.HNO,y m is 1.81, at 5:4 mole/1
HU03 it is 2-50- Fig. 2 shows a as a function of acidity of the aqueous
phase. a passes a maximum at 6 - 7 mole/1 HN03. The decrease of a with
higher aoid concentrations is explained by the formation of
(TOA.M'03),HN03 and by the occurrence Of U02(NO3)3 iins. In Fig. 3 a is
represented as a function of [H+1 , in Fig. 4 as a function of the uranium
concentration. o-xylene and carbon tetrachloride served as solvents. With
very low uranium concentration in the aqueous phase a is almost independent

by the reduction of concentration of free TOA 'HHC as a result of the
extraction process. In Fig. 5 the equilibrium disiribution of uranium
between aqueous and organic phase is shown at 0-47 mole/1 TOA.HN03,
dissolved in O-C6H4(CH3)2 or CC14. Table 2 gives the dependence of a on
the concentration, of uranium in the aqueous phase and the values for the
stability constant X, of the cc p1axA(TOA.H)UO2(NO3-)3 . These values were
sufficiently constant only at uranium concentrations in the organic phase
up to 0.10 mole/1. They amounted to 2.02�0.12 for 0.47 mole/l TOA.HNO 3
in CC14 and 2.88t0.11 in o-C 6H4(CH3)2 . The absorption spectrum recorded
by a C~ -2M (SF-2H) rec'ordizig apectrophotometer of the organic uraniuml
solutions in TOA is shown in Fig.'6. It considerably differs from Me-
spactrum of uranyl nitrate, it is similar-, however2 to the absorption
spectra of the trinitrate uranyl compounds. The optical density of
UO 2(NO3)2 solutions in methylisobutylketone was measured at different

tributyl phosphate (TBP). The present investintion deals with
the reaction mechanism of extracting' UVI and U 'with DE14PA fkom
HC1 solutions; the stability of the uranium compounds, extracted
from the RCI solutions with the two aforementioned reagents Is
compared. Of each reagent 20%soLutions, in carbon tetrachloride,
were used. Details of the preparation of uranyl chloride (U02CI2)
and of uranium tetrachloride (UC14) are given. EquaL volumes of
the 2 phases (10 ml each) were used for the extraction process
which lasted 10 minutes; this time sufficed for attaining

equilibrium. The solution was allowed to settle for 18 hours
(UVI) and I hour (UIV) respectivelyj thereafter the phases were
separated. Each phase was analysed for its uranium content and
the dispersion coefficient defined as the ratio of the
concentrations of the element in the organic and in thp aqueous
phase.UV,During the extraction of hexavalent uranium it was found
that is extracted to an appreciable degree with a 20% solution
of DXMPA in CC14 at acidities > 2N HC1. The tetravalent element
is extracted satisfactorily with 20% solutions of D9MPA and TSP in
CC14 only at concentrations of HCI/'*4 -5 N HCl. The complex
U02CI2,2DEMPA was formed In the Inveitigated acidity ra.~*e (up to'
5N HCI); tetravalent uranium forms the complexes UC1412DZWA and
UC14Z2TBP. The ratios of the stability constants were calculated
for he complexes U02C12.2DEHPA and U02CI2.2TSP (113 + 16) and for
the complexes UC14.2DEMPA and UC14,2TBP (approximatei7y 3oo).
