determine how the movable hydrogen of the donor is distributed
between the acceptor and oxidator in the concerned reaction.
As hydrogen donor ascorbic acid was used, as hydrogen acceptor
methylene red. As catalyst copper sulphate and ferrous sulphate
were used. The methylene red molecule is reduced to a colorless
leuco compound (Ref 3). Methylene red behaved in the previous
tests quite analogously to the ortho dinitrobenzene (Ref 1).
Out of the fact that the reduction of I molecule methylene red
requires 2 hydrogen atoms follows that only 1/5 - 1/3 of the
atoms of the movable hydrogen of the amount of ascorbic acid is
used for it. The ascorbic acid is oxidized at this reaction.
The remaining movable hydrogen of the donor is oxidized by H 202'
This utilization coefficient does not depend on the concentra-
tion of the reaction participant. The ferrous sulphate operates
at the said reaction only in presence of the H 202 and not of the
molecular oxygen. But the latter operates in this sense only on
the catalytic effect of copper ions. The corresponding experi-
ments gave an analogous result as above, but showed a smaller
consumption of ascorbic acid. This can be ascribed to an
Card 2/4 exacter titration possibility than it was possible in the first
I.

case. The said oxygen consumption was in oxygen stream 4-5 times
greater than on adding H202* A b o u t t h e m e c h
a n i s m o f t h e i n d u a e d r e d u c t i o n
The strong peroxidase effect of iron- and copper ions is known
(Ref 4). The copper ions also strongly catalyze the oxidation
of the ascorbic acid by the molecular 0 2 whereat H202 results.
On this the idea of the formerly described (Ref 1) induced
reduction can be based: the H 202 introduced from outside or
formed as above is activated peroxidaselike by copper- or iron
ions. This H202 oxidizes the ascorbic acid monovalently. There-
by arises its free radical - the mono dehyd-.ro ascorbic acid
(Ref 5). These radicals are a very strong reducing subetance.
Therefore its single movable hydrogen atom gets the capacity to
let transfer itself more intensively to the more difficultly
reduceable acceptors with a low redox potential as methylene
red, ortho dinitro benzene, and others. In this way the oxida-
tion of the first movable hydrogen atom effects the activation
of the second atom of the ascorbic acid and induces thereby the
Card 3/4 reduction of the acceptor. This is only possible in the presence
Induced Methylene Red Reduction With Ascorbic Acid SCV/20-126-5-6o/6a,
of copper atoms. At the presence of H 202 this reaction takes
place also in the presence of iron ions. The activated H-atom
of the mono dehydro ascorbic acid can of course be transferred
also on an active oxidator. Therefore, the utilization coef-
ficient of the movable hydrogen of the ascorbic acid does not
equal 5-d' but it is much smaller. The reason is that the ascor-
v70
bic acid oxidized by 0 2 is only the oource for H 202' The arising
of free radicals of the ascorbic acid was proved b A - I' Drokin

TEXT: To explain the oiological effects of ultrasound it is oft
interest to investigate the effect of ultrasound-on the oxidizing
and reducing reactions. One of such reactions is the transfer :)f
.-_ydro,gen _Lrom the donor (ascorbic acid) to the acceptor (the itiethyl
red) in the presence of ions of copper as catalyst. It was found
that ultrasound of a I-equency of 8bO xc/s and 7 vl,/cm2 intensity
considerably accelerates the transfer of hydrogen in this reaction.

TOPIC TAGS: nitrate reduction, hydrogen peroxide, algae, chlorella, nitrate,

ABSTRACT: The authors investigated whether an external introduction of a physio--
logically admissible'concentration of hydrogen peroxide, under certain conditions,
would affect nitrate reduction in a plant and, so, produce an increase in ammonia
formation. The experimental subjects were one-called green algae (chlorella vulgaris.
a thermophylic, variant). From some of the experimental results, it was shown that
the addition of hydrogen peroxide to the nitrate solution, under either night or
daylight conditions, increased ammonia production from the plant to the surrounding
environment by an average of more than 1-1/2 times. When the nitrogen wag depleted,
however, the chlorella did not give off ammonia. It was concluded, therefore, that
for green plants, the biosynthesis of albuminous matter from nitrates was accomplish-

Abstract: T11o eTfect of soaking at 900-1,3000 on carbide and sulfide inclusicms in
various steels and on ferrous oxide in armco-iron is studied, Chemical, microscopic,
amd metallographic analysis methods were used.. It is shovn that heat treatment of
specimens at 900-1,3000 for 30 minutes does not change the composition and the shape
of a sulfur and oxygen inclusion in carbon steels or in alloyed chromium and nickel
steels, and leads to a noticeable spheroidization, starting with 1,0000,_of ferrous
oxide Im armco-iron. As a result of a longer beating at 1,3000 (15 hours and more),
there is a partial spheroidization of the sulfides in steels and a contamination of
the nonmetallic residue by oxides of iron and chromium. -In steel alloyed with

ABSTRACT: As is separated from Fe by means of passing a solution of the
alloy through an ion exchanger containing 60 g of sulfocarbon or
40 g of KU-2. The As is precipitated in the solution by a mag-
nesia-ammonia mixture. MgNH4AsO4 is filtered out and is dis-
solved in HC1 (1:1); after adding NH40H, a buffer solufion, and
an indicator (acidic, dark-blue Cr), the As is titrated with a
solution of trilon B. Another method of titrating As with trilon
B is also described. The results of determination of As in fer-
roarsenic are presented in a tabulated form.

pp 1074 - 1077 (USSR)
ABSTRACT: The district mentioned in the title is situated in the soAth-
western part of the Kursk magnetic anomaly ( Mal) in the iron-ore
district of Belgorod. The deposits mentioned in the title were
discovered by prospecting in 1953. In the South they overlie
denosits of Proterozoic iron ores and in the North and East they
contain workable coal beds. The author investigated these Ade-
posits in detail in 1956-58. Lower Carboniferous is represented
also in this case by the Visean stage which contains the follow.-
ing horizons: Stalinogorskiy, Tullskiy, Lleksinskiy, ',"ikhaylovs-
kiy, and Venevskiyq furthermore in the South also the Serpukho,,rs-
kiy lower stage. These deposits are stratified on a considerably
structured surface of the pre-Cambrian fundan-,ent and are covere6
by I'desocenozoic deposits (290-470 m thick') . From the structural
point of view the Lower Carboniferous deposits form the northern
edge of the Dnepr-Donets depression.. They slope to the South---West

TITLE: Determination of cerium-containing inclusions in alloy steels
:..~PERIODICAL- Zavodskaya laboratoriya, v. 29, no. 3, 1963, 283-286
TEXT: Cerium compounds formed by introducing small amounts of cerium in
alloy steels were investigated. Steels containing 0.05 - 0.12% Ce,
0.60% bin, 0-30 - 0.40% C, and 0-3~a S were-used. The nonmetallic phase
was separated by dissolving the steel specimens in the usual iron sulfate
electrolyte with complex formers. The anode alime'was first treated with
30% copper ammonium chloride solution containing 1% FeSO and 5~ ammonium
4
citrate, and then with iodine solution in potassium iodide; subsequently,
the slime was studied petrographically and by x-ray anal sis. Cerium
compounds were found in the form of sulfides (CeS, Ce 2S 3~ in the steels
investigated; no oxysulfide compounds were detected. Since cerium sulfides,
soluble in hydrochloric acid, are insoluble in iodine solution, they can

be easily separated from iron and manganese sulfides. The amount of
cerium inclusions in the steel was independent of the total cerium content.
This was due to the high degree of liquefaction of cerium sulfides and
their irregular distribution over the cross section of specimens. The
electrolyte residues contained much more cerium than the sulfide phase.
Cerium was irregularly distributed in the sulfide and the carbide phase.
In the carbide -ohase, it was contained in the cementite lattice which was
confirmed by x-ray analysis. There are 5 figures and 3 tables.

ABSTRACT: Two waveguide phase-shifters are considered. One of these
comprises a ferrite plate of thickness H , which is placed near
one of the narrow walls of the guide. The second phase-shifter
comprises two ferrite plates which we parallel to the narrow
walls. The longer walls of the guide )xave a length a , and
the plates are magnetised perpendicularly to the axis of the
system. The plates are characterised by a permittivity e and
magnetic parameters IL = 0.9 and a ; the permettivity and
the permeability of the guide were assumed as co = 140 = 1.
The propagation constant y of the guide with one ferrite plate
can be found by solving:

pp 14?1-1484 (USSR)
ABSTRACT: The work deals with the problems of the general theory
of cavity resonators filled with tensorial media. The
method of analysis is based on the application of the
eigen functions of a cavity resonator which was proposed
by Frankell (Ref 7) and used by Kisunlko for ieveloping'
a resonator theory for the case of scalar media (Ref 8).
The principal concepts of this theory are here generalised
and extended to the case of media with tensorial parameters
First, a closed volume, V , limited by a3i ideally
conducting surface S and filledKith a medium. whose
tensorial parameters are V' and 4 is considered.
The parameters V and V are arbitrary functions of the
co-ordinates (Figure 1). For the case of free undamped
oscillations in the resonator, the complex field amplitudes
for the m-th type of oscillation 0hould fulfil the
uardl/5 Maxwell equations:

m
and the boundary conditions given by Eq (2), where no
is a unit vector normal to the surface 8 . The field
vectors can be represented by Bqs (3), where e and h
are complex amplitudes which are related by Bq (4). Fro
the above, it follows that the eigen vectors and F
im m
of the resonator should satisfy Eqs (7) and (8), where '
WM is the eigen frequency'of the resonator. This can be
expressed as a ratio of two volume integrals, as is shown
in Eq (9). The orthoganality condition for the electrical
eigen functions of the reso-hator is given by Eq (13),
while that of the magnetic eigen functions should satisfy
go (14). If the medium is not lossless, the tensors
7- and V are not Hermitian functions and the eigen
(;ard2/5 frequencies of the resonator are complex and can be

where nI/2w" is the quality factor of the resonator
Qn = W n
for the n-th eigen oscillation. In the case of forced
oscillations-in the resonator, the Maxwell equations are
w3itten as Eqs (18) to (21) and these should fulfil the
boundary conditions given by Eqs (22) and (~3) (Figure 2).
The field of forced oscillations of the system is in the
form of series expressed by Eqs (24) and (25), where
I
Em and -9m are eigen functions of-,the resonator, as
derived in the earlier formulae, while the coefficients

determined. It is shown that ~o can be determined from
Eq(26) and (P from Eq (29). On the other hand,
Uard3/5 coefficients em and hm are expressed by Eqs (39) and
Resonators with Tensorial Media 6OV/109-3-12-b*/i3
(40), where F m and I m are given by EqB (3?) and (38).
If the losses in the medium are comparatively small,
they can be taken into account by substituting the
frequencies in Bqs (39) and (40) by the complex frequencies
of Eq (l?). In this case, the coefficients e m and hm
are expressed by Eqs (41) and (42). From the above, it is
seen that the field of forced oscillations in a resonator
with a tensorial medium can be determined, provided the
eigen frequencies and eigen functions of the resonator are
known. In a waveguide resonator with a scalar medium,
the eigen frequencies are given by expression (43) where
I is the length of the resonator, n is an integer and
Y(w) is the propagation constant of the waveguide which
can be regarded as a known function. In the case of a
tensorial medium with non-reciprocal propagation constants,
the eigen frequencies of the resonators (which are
similar to those shown in Figure 3) can be determined from
Eq (46), where y and y- denote the propagation
constants for two opposite directions.

A spectrum of the spin waves in the unlimited medium is
given in figure 3. Under certain conditions they are connected
with homogeneous oscillations and exercise a considerabls~
influence upon the processes takinC place in ferromagnetic
semiconductors within the nuperhigh frequency range. An
explanation for the observed course of temperature and the
duration of relaxation r is given by the theory (Ref 20)
which brings the relaxation processes with spin waves and
magnetic heterogeneity into connection, especially with the
non-ordered distribution of the ma6-netic ions in lattice
point. It was found that Ir as well as the g-factor can be
exactly measured only on monocrystals. The effect of the
domain structure is also of outstanding importance. The
results found for unlimited media may also be applied to
bodies with limited dimensions if the tensor T does not hold
for the external but the internal alternating field. Un.-
fortunately, it is only possible to solve a very low nlimber
of boundary problems. Of the approximation methods, on-I.,-, '7~m of

the method of"infinite space" (Refs 49P50) and the perturba-
tion method with a quasi-Btatic approximation of the internal
field (Refs 51,52). Apart from theory, also apparatus were
developed during the past 6 years in the case of which it is
possible to make use of the properties of ferromagnetic
semiconductors for the solution of practical tasks of super-
high frequency. The principle of such apparatus is funda-
mentally clear (Refs 56,57). The main problem is now the
supply with auitable materials and the necessary parameters.
In the short;..wave range of superhigh frequencies it is
relatively easy to fulfill the requirements. Considezable
difficulties arise, however, in the case of lloner -,vave:,.

the width of the resonance curve,
in ferrite single crystals
3, no- 1, 1961, 19-31
TEM One of the most suited methods for studying relaxation processes
in ferromagnetic materials is based on the analysis of the temperature
dependence of the width (24H) of ferromagnetic resonance absorption curves
in ferrite single crystals. This paper reports on such measurements.
Spherical yttrium-ferrite single crystals with a garnet structure, and
manganese and magnesium-manganese ferrites with a spinel structure served
as specimens; the measurements were made in the range from -1960C to the
Curie point of these ferrites. The growing of the single crystals is
described briefly. A standard method has been used to determine 2AH at
9100 Me. Altogether 6 specimens have been investigated, and their charac-
teristics are given in a table. Fig. 2 shows 26H as a function of.
temperature for these 6 specimensi Fig. 3 shows Al' (T) for specimen no. 1

Temperature dependence of the ... B102/B212
(All denotes the imaginary part of the diagonal component of the lloxtornalll
res
susceptibility tensor at the point of ferromagnetic resonance). 2AH is
determined in ferrite single crystals by the following processes: Inter-
action of homogemous precession with spin waves; relaxation processes, in
which magnetic impUrity ions with a stron frequency 5spirlattice relaxa-
tion take part; excitation of spin waves fwith k,-10 -10 cm-1) as a result
of scattering of a homogeneous precession from microscopic magnetic fluctua-
tions which are caused by a random distribution of magnetic ions among the
lattice sites; a widening of the resonance curve, caused by the roughness
of the specimen's surfacel and incoherent relaxation processes due to
thermal fluctuations of the magnetic moment. The latter effect entails a
rapid increase of 2&H when approaching the Curie point. When analyzing
the 24H - f(T) curves, it is assumed that n processes that influence 2AH
are additivet 2,&H A detailed discussion is then given of the
n n
effect of the roughness of the specimen; of fluctuations near the Curie
point; of rare-earth impurities; and of impurities and magnetic disorder
in spinels. The results of the investigation lead to following con-
clusionss 1) The component of 2AH, due to the roughness of the specimen,
Card 2/7

Temperature dependence of the ... B102 B212
is approximately proportional to the magnetization; the factor of propor-
tionality is not a function of the ferrite composition. 2) The relpation
frequency of rare-earth impurity ions in Y-ferrite grows from 2 .10 to
6-1013 when heating the specimen from -1960 to +200OC; at room temperature
it has a value of 3-1013- 3) The relaxation mechanism characteristic of
spinel-type ferrites leads to a 2AH component of several oersteds caused by
a spin-wave excitation; therefore it is possible to measure resonance curve
widths of less than 10 oersteds in single crystals of such ferrites. 4)
The 24H component caused_by, thermal fluctuations of magnetization increases
in proportion to (T.- T) 172 when approaching the Curie point. 5) Due to
the fact that the latter component grows with increasing temperature, while
the components caused by impurity ions and by the roughness of' the specimen VK
decrease, all 2AH . f(T) curves have a minimum above room temperature.
Position and distinctness of this minimum is a function of the values and
temperature dependence of these components. Increasing roughness, e.g.,
brings about a shift of this minimum to higher temperatures. The authors

TITLE: The authors studied the effect of electron-induced anisotropy of 0
polycrystalline yttrium garnets upon ferromagnetic resonance from 4.2-300 K.
The measuring technique used in the temperature range of 77 - 3000K had
been described in aprevious paper (A,. G, Gurevich et al,, Fizika tverdw~o
tela.. ~, no~ 1, 19 (1961). A square rooonator was dipped into liquid
helium. with the specimen between 4.2 and 770K.. With waves the

from the dependence of the reflection fnctor IV) on the magnetic field, as
recorded by an z3flfl-09(EPP-09) voltmeter, An example is illustrated in Fig.l..

with a purity of 99-995~c, the said rise cannot be attributed to rare-earth
impurites. Present results show that the induced anisotropy of polyarystal-
line yttrium garnet is due to Fe24, ions, To clarify the establishment of
induced anisotropy with time, the authors determined the time dependence of

not change noticeably above 1300K., At lower temperaturea, 11"I changed
abruptly during rotation, and then returned to its original value (Fig,

It is believed that induced anisotropy is not yet fully established immedi-
ately after rotation through 900 and that the resonance curve at i given
temperature shifts by Hc toward stronger fields relative to the static
curve. lie 14 550 oersteds is obtained at 770K, and Ht' :z 200 oersteds at
900K, It follows from a discussion of this result that in additicn -.o the
processes that are observed after rotation, also other processes -.ake place
which have time constants considerably smaller than the time o-f rotations,
These processes are held responsible for the major Dart of the induced
anisotropy field.. As is shown,,~-iuperposition of several procenses~ with
different time constants and activation energies of the order of 0.05 ev
