TITLE. Investigation of the complex formation of thorium
with mandelic and a-oxyisobutyric acids
PERIODICAL: Radiokhimiya,.V.5, no.2, 1963, 249-258
TEXT: The complexing with the acids was examined with a view
to their utilization as eluants in the purification of Th by ion-
exchange methods. To 'this end the adsorption of 234Th was studied
on cation exchanger resin Dowex 50 and 5 in the Na form. The work i
was carried out at the pH's of 1-75 to 2.5 to minimize the
adsorption of Th on glass and because at this pli range the
distribution coefficients were sufficiently large. The instability'
constants were calculated at p1l = 2.2 by two methods, of which the
inothod of S. Froneus (Acta Chi., Scand., v.4, no.1, 1950, 72) was
considered the more reliable. The first instability constanta for
mandelic and oL-isobutyric acid were 1.82 x ict-3 and 3.83 X 10-5
respectively. The second coristants were 0 *67 x 1o-5 and
2.44 x 10-6, and the third constants 1.92 X io-7 and 8.34 X 10-9
respectively. Changes in the concentration of mandelic acid front

0.01 to 0.1 M decrease the distribution coefficient by two orders
of magnitude and a similar trend is shown for cL-oxyisobutyric acid.,
The first complex ~Th A] 3+ forms at the concentration of addend
of :~., x 10-3 M. During furthor increases of the concentration up
to about 10-2 M the composition of the complex changes to
[Th A,]'*, [Th A,]+ and ~Th A3.5]0'5+. In general,
a-oicyisobutyric acid forms more stable complexes than mandelic
acid and therefore is a more suitable eluent for the isolation of
Th by ion exchange methods.

TITLE: Some regularities of comploxing of pentavalent actinides
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 149, no. 3, 1963, 611-614
TEXT: On the basis of compositions and instability constants of complexes
of pentavalent Pa, Np and Pu with anions of some acids (determined by
means of the ion exchange method), the tendency of these elements to form
complexes was shown to be much stronger than is generally supposed. This
tandency is much the same for the elements mentioaed, as they form
complexes of identical composition and approximately identical stability
WItFanions of suitable acids. The tendency of the addends to form
complexes decreases according to the following sequence;

Some regularities,of B117/B186
Although no complete data exist for Np(V) and Pu(V), this sequence can
also be applied for these elements owing to conformance of instability
constants. Instability constants of complexes formed by Pu of different
valence with the same addend show that Pu in the pentavalent state has the,
weakest tendency to form complexes. On the basis of the similarity of
oomplexing properties of pentavalent Pap Hp and Pup and of the
quantitative data available, conclusions may also be drawn as to the
composition and stability of complexes of pentavalent uranium with the
acids mentioned. One of the properties of actinidea which serves to
prove their position in the periodic system of elements is their behavior
during ion exchange. Pap Np aAd Fu in pentavalent state were found to
behave similarly during ion exchange. 'There are 1 figure and 1 table.

TITLE: Alechanical-chemical dispersion of metals In dynamic contact with polymer
SOURCE: Fiziko-khtmicheskaya mckhanika materialov, v. I., no. 5, 1965, 527-530
TOPIC TAGS: mechanical failure, metal property, polymer, polymer physical chemistry
ABSTRACT: The authors discuss some of the results obtained earlier on the mechanical-
chemical processes In the mq~al-polymer contact region. Under laboratory conditions, the
working surfaces of textoliteJ'damples showed microscopic particles of a mekal with a
considerably greater hardness than that of the metal of the roller In contactkivith the samples.
An analysis of other data, as well as the results of earlier experiments on the dispersion of
metal powders In contact with polymers, led the authors to the assumption that the surface
layers of polymers are conducive to the strengthening and brittle fracture of the metal surfaco
which are In dynamic contact. In this connection, the authors conducted investigations to
determine the role of the polymer In the process of dispersion of the surface layers of the
metal. Comparative tests were made on the dispersion of Iron in a ball mill with a polymer
(emulsion polyethylene, 5% by wt.) and without a polymer. The experimental data show that,
in the process of mechanical load the polymer particles are chemically activated and

Interac-t with the exposed crystal surfaces of the metal, which causes the Intensive dispersion
of the metal. Apparently, the chemical activation of the polymer Is due to the mechanical
destruction of Its macromolecules and the formation of free radicals during this process.
Other experiments showed that polymers, at the Instant of their destruction, have a con-
sider2bly higher capability for affecting the dispersion of metals than surface-active sub-
stancea Alt Is established, therefore, that a high-molecular substance at the instant of
mechani 1 cracking is capable of activating the process of deformation and the destruction
of a metl The practical observation of wear of the working surfaces of metal parts working
In contact with plastics testifies to the mechanical cracking of macromolecules of the polymer.

ABSTRACT: The authors carried out epidemiological Investigations during 1959-1962 In the
steppe, forest-steppe, and taiga areas of the Cheremkhovsk region of Eastern Sayan - These
investigations revealed that the degree of contact of the population of these various areas with
the natural focus of tick-borne encephalitis is intimately associated with the character of its
economic activity and living conditions. It is suggested that for the population of villages
involved In the lumber Industry the living conditions lay at the base of this contact with the
focus, whereas for the population of villages involved In the wood-products Industry, the
industrial factor played the major role. The authorsdeem it expedient to differentiate the
system of prophylactic measures for the populations involved In the different industries: for
thJe wood-products workers the measures should Include vaccination and the creation of tick-
free zones around the populated points and for the forestry workers measures should be taken

PERIODICAL: Stanki I Instrument, 1960, No. 12, pp. 6-9
TEXT: According to Investigations carried out by the VNIITS it was found
that the best sintered tungsten carbide grade for the manufacture of blanking die
parts is the BK 20 (VK20) grade. Moreover, it was found that "he most efficient.
method of finish machining of sintered carbides Is the grinding by diamond wheels,
ensuring an accuracy of up to the Ist class inclusively and a surface finish up
to the 13th class. To find out the most favorable characteristics of diamond
wheels and diamond grinding conditions, surface and cylindrical grinding of
blanking die parts made of VKPO sintered tungsten carbide Ivive been studied by the
NIIAmaz. VK2O specimens with the dimensions 47 x 59 x 30 urn and control Specimenq
of 4 x It x 110 mm were preliminarily machined with the V& 46-60 CMIK (KZ46-60 SMIK)
wheels. Then they were ground with diamond wheels cooLed with a _J4 soda solution.
The following points were investigated: 1) surface finish (the specimens were

TITLE: Diamond wheel grinding for hard-alloy mill rolls
PERIODICAL: Stanki i instrument, no. 7, 1961, 28-31
TEXT: Hard-alloy rolling mill rolls could not be finished to the required
class 12 mirror finish at the Leningradtkiystaleprokatnyy zavod Leningrad
Steel Rolling Plant) and Beloretskiy provolochno-kanatnyy zavod ~Beloretsk
Wire Rope Plant). The diameter tolerance for these rolls is 0.005 ram; fi-
nish-grinding K 60C112K (KZ60SM2K) wheels and superfiz--ishing were employed.
The rolls were 2ull, and the rolled metal had to be polished after rolling.
This was the reason why hard-alloy rolls were not much used despite their
advantages and the fact that they had a 20 - 50 times higher wear resistance
than,steel rolls. KIIAlmaz conducted experiments with diamond wheel grind-
ing at the Leningrad Steel Rolling Plant and achieved the required mirror
finish. The article contains a detailed description of the experiments and
their results, and final recommendations. The experiments consisted in
grinding (3K8 (VKB) alloy experimental rolls 70 mm in diameter and 30 mm
long, by means of a grinding machine with 28C1 rpm spindle velocity and

AIM 200xlOx75 (APP200xlOx75) diamond wheels with an organic bond. The
coolant consisted of 0.60% sodium triphosphate, 0.10% sodium nitrate, 0.05%
vaseline oil, 0.30% borax, 0.25% calcined soda, and 98-70% water. Class 12
mirror finish was obtained by diamond wheels with a granularity At-f-10 (AM-
10) and a 50~ diamonds concentration; the wheel speed was 29.3 m/sec, roll
velocity 30 m/min, cutting depth 0.0025 mm and longitudinal feed 0.3 m/min.
Fifteen last-finish passes were made. Diamond wheel grinding resulted in
a reduction of labor-consumption of up to 8 times in the finishing opera-
tions and eliminated cracking caused by green silicon carbide wheels. Po-
lishing after rolling was no longer necessary. There are 12 figures.

ABSTRACT.* Within the limits of experimental accuracy the rest masses of
0- and T-memons are equal and this equality is called the
"degeneration of K-meson* with respect to symmetry". In this con-
neotion the examination of the behavior of the corresponding
quantities with reflections Is of interest. Besides, such ex&mi-
nations are interesting themselves. Besides the well-known pos-
sible symmetries with respect to space and time reflections there
is an additional possibility which is here called "anomalous
symmetry".
It in purposeful to determine the transformations of the quanti-
ties with respect to on* or the other group with an accuracy
leaving one factor arbitrary. Well-known examples for the occur-
reno* of such factors are the spinors or the wave functions of
a system of particles which obey the F M I statistics. The corres-
ponding mathematical notions are the eo-called projective re-
presentations of one group. Here the representation of a group

of reflections consisting of the following four elements is
examined: the element of the unit and of the operators of the
timo-dependent, spatial, and time-spaoe reflections. With trans-
positions of the operators Tt (a certain projective representa-
tion of the reflection groups) the quantities transformable by
the operators of the representation have four possibilities of
symmetry. The only additional possibility follows if the demand
of transpossibility of the operators in renounced. Then the re-
lations betwe*n the operators oan be expreoe*d by a matrix. In
the simplest case, with the transformation of scalar quantities,
the operators can be written in the form of three anti-oommuting
matrices of second order which are analogous to the well-known
PAULI matrices. The quantities to be transformed ("scalars with
anomalous symmetry" form numerical pairs which do not change
during the transformation proper and which transform during r*-
flections according to the matrices already mentioned. The
irreducible representation of the LORENTZ group, together with
the reflections, decomposes into two representations of the

LORENTZ group proper. Thereby four normal and one not normal
possibilities exist. This and other considerations permit the
subdivision of the particles into classes with normal and not
normal symmetry. Attributing the not normal symmetry to the
K-mesons and the normal one to the pion*, the same normality
would follow for the particles A , Y- just an for the particles
npr:-'. For this purpose the consideration of one reaction with
strong reciprocal effect suffices. The X-2090n can exist in two
different states with different space symmetry and equal mass.
