TEXT: In order to use topographic maps, 1 10j000 and I : 25,000 scales,
in water-econoiny purposes, the author proposes to complement their contents with
special hydrographic data. In particular, it is expedient to provide topographic
maps with a f'uller characteristic of water conditions of rivers and lakes, to
subdivide channels according to their destination (irrigation, wate-r-collecting
and overflow, drainage), to single out irrigated lands (irrigated by gravity
flow and mechanically, as well as estuary irrigated), and to denote the level of
ground waters and their discharge. Moreover, specihl objects (water trough
sites, pumping stations, water towers, hydrometric stations, hydrotechnical tun-
nels,etc.) should be designated on the maps. P. Kuznetscv

ABSTRACT: The author inspected various building and mining industry
schools and found that the results of teaching methods were
far from satisfactory. Some schools showed very good results,
but in many others the students did not even know how to use
the simplest tools. The author cites many such examples. She
finds that the fault li&s mainly with the lack of knowledge
of young teachers and with the careless attitude of the foremen
in charge of practical instruction.

ABSTRACT: The author investigates the possibility of using high power pulsed
light sources in Raman spe troscopy.~-To this end, a solution is obtained for the
Schroedinger equation of a system of particles with a discrete energy spectrum,
subject to simultaneous action of two pulsed generators. The quantum mechanical
system, subjected to the pulsed generators is assumed to h&ve a certain number of
particles with nondegenerate nonequidistant levels. The frequencies of the
generators are different. The solutions obtained for the Schroedinger equation
show that such an excitation will give rise to signals which are the analog of
spin induction and spin echo and that the information contained in these signals
is more abundant that thatt contained in ordinary Raman signals for the scattering

of light, radiowaves, and phonons. If the generator intensity is sufficiently
strong, the pulse duration can be chosen so short that the excitation processes
in the medium will not depend on the relaxation mechanisms. The solutions in-
dicate the existence of a great variety of nonequilibrium states of matter., which
can be used to extend the capabilities of pulsed Raman spectroscopy. Signals
obtained for the C135 ion in NaC103 are described by way of.an example. The
author is deeply grateful to U. Kh. Kowillem for guidance.- Orig. art. has:

TITLE: Free induction signal in exchange pairs
SOURCE: Zhurnal eksperimental'noy i teoreticheskoy fiziki, v. 50, no. 4, 1966,
936-942
TOPIC TAGS: magnetic resonance, wave equation, signal shape, oscillation,
temperature dependence
ABSTRACT: Equations for the initial amplitude and shape~of the free induction
signal were obtained under normal conditions of magneti resonance, and a dependent-
wave equation for the interaction of two coupled spins in fields of-arbitrary
intensity was employed. The temperature dependence of the signal was taken into
account. It was shown that due to the relaxation terms, the decay of the free
induction signal is oscillatory. The signal amplitude contains oscillations with a
frequency proportional to the interaction constant of the bound paired spins. It
was shown that the variation in the shape of the free induction signal depends on
temperature T. Near T = 0, the decay of the free induction signal becomes weaker.

TITLE: Spectroscopic Analysis of Ferro Alloys and Chromium for
Non-ferrous Metal Impurities
PERIODICAL- Zavodskaya laboratoriya, 1960, Vol. 26, No. 12,
pp. 1364-1366
TEXT: In the present paper the spectroscopic methods of determining-lead,
tin, antimony, bismuth, arsenic, zinc, and cadmium in ferrochromium, chro-
mium, ferroniobium, ferrovanadium, and ferromolybdenum are described. De-
termination of these impurities in the relatively high-melting substances
with multiband spectra may be carried out by means of fractional distilla-
tion in the arc by means of an evaporator or by a previous chemical pre-
paration. If the impurity content is not too,low, the fractional distilla-
tion from the channel of the "cup-shaped" electrode (Ref. 1) in the a.c.
arc is most c6nv6nient., The test sample was a Dowder to which sulfur,
soda, and graphite were added to increase speci. -insitivity. The results
obtained by analysis on the basis of the "absolut -31ackenings of the

bands were sufficiently reproducible. The standards were prepared synthe-
tically from the pulverulent sample with the lowest impurity content,
the samples with solutions of known impurity content were wetted and
dried. As the decomposition temperature and the sublimation temperature
of the oxides of impurity elements and the evaporation temperature of
the metal impurities is near the heating temperature of the sample in the
electrode channel, the conditions of entry into the arc are the same
for an element determined from samples and standards in the case of quan-
titative evaporation. As an example, the evaporation curves of lead from a
standard sample ferroniobium and from synthetically prepared standards
are mentioned (Fig.). The initial standard solutions are specially
prepared for each impurity , because all of them together cannot be kept
in solution. Each solution contained 0.1~6 ofthe impurity. The weighed
portion of 80 mg of the average sample, granulated to 150 to 200 mesh,
is introduced into a channel of a carbon electrode having a diameter of
6 mm. As a second electrode, a carbon rod with a diameter of 6 mm was
used, which was ground to the shape of a truncated cone. For excitation
of the spectrum, a AF-2 (DG-2)genEmtar with 15-16a-was used. For the deter-
mination of tin and arsenic in ferrochromium and chromium and of arsenic

in ferroniobium, elementariy'siiilfur in a quantitk of 1/10 of the volume
of the analyzed substance is added to the samples. For suppressing the speo-
trum of the basic material in the analysis of ferrovanadium and increasing
the sensitivity in the determination of tin in these alloysp graphite
in a quantity of 0.25 - 0.50 of the volume of the analyzed substance is
introduced into the sample. Them c n-~e (ISP-28) speatrograph having a
slit width of 0.010 mm was used. The analytical bands are given in Table 1.
The analysis is carried out according to the three-standard-technique.
The reproducibility' of the determinations' is ahara6teriized by the mean
square error of the determinatio'n of three samples, and amounts to
6 - 12%. The limits within which the certain impurities may be detected
are given in Table 2. In one -working layer, 10-15 samples may be analyzed
for all impurities by means of the method described. There are I figure,.
2 tables, and 5 references: 4 Soviet and 1 US.

TITLE: Extraction of Nitric kcid by Derivatives of Butylphosphinic
Acids
PERIODICAL; Doklady Akademii nauk SSSR, 1959, Vol 127, Nr 3,
pp 578 - 58o (USSR)
ABSTRACT: The present information constitutes part of the work on the
extracting properties of some butyl-phosphine compounds;
tributylphosphate (TBPh), dibutyl ester of butylphosphinic
acid (BPhSW), butyl ester of dibutylphosphinic acid (DPhBE)
and tributylphosphine oxide (TMO). The acid derivatives
mentioned in the title are more efficient as extracting
agents than TBPh for important elements such as uranium and
plutonium. Since this extraction is usually carried out from
nitric solutions, it becomes necessary to investigate the
distribution of HNO 3 in the aqueous solutions and the so-
called organic solvents. No data have been published in this
Card 1/4 connection (except on TBPh, Refs 2-4). This gave reason for

the present investigation. The dependence of the HNO
distribution on the concentration of used extracting agents
and on the presence of uranyl nitrate in the solution, was
studied here. Saturated, highly boiling hydrocarbons (SHC)
and CCl4 were used as diluents of the extractin.- agents.
According to the data given by table 1 showing the experi-
mental results, the extraction of HNO 3 increases with an
increased concentration of the extracting agent in the SHC.
The HNO3 extraction rapidly increases during the transition
from TBPh to TBPhO in the series (Fig 1). An increase of more
than 5o% of the concentration of BPhDE in the diluent, caused
an abnormally reduced acid extraction, compared to other
extracting agents of the same series (Fig 1 and Table 1).
During the HNO extraction with a 5% solution of TBPhO in
3
SEC a second organic phase was separated which apparently
is a combination of TBPhO and HNO 3 (Ref 2). When C01 4 was
Card 2/4 used, this second phase did not occur: Table 2 gives the

extraction results by means of the same extraction agents,
in the presence of uranyl nitrate. Within the concentration
sphere of the extracting agent-00'J 50%, the HNO3 extraction
is reduced according to the rule, in the series of TBPh
to TBFhO. This is probably due to the increase in the ex-
traction of the uranyl nitrate and thus also due to the
displacement of HNO 3 from the organic phase to the aqueous
phase. This displacement is the more intensive, the more
effective the extraction of the extracting agent of ~ranyl
nitrate (Tables 1 and 2). Consequently the presence of uranyl
nitrate influences HNO extraction less and less with-a

r~J5o% BPhDE concentration and is finally hardly noticeabl'eo
All this proves that the extractability forms the following
series: TBPh ( DPhBF, $PhDE
