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. Induced Methylene Red Reduction With Ascorbic Acid SOV/20-126-5-60/69 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 (Krasnoyarsk Institute of Physics of the AS USSR~ on Para- magnetic way.

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.

TITLE: On the effect of hydrogen peroxide on nitrate reduction in green pjants SOURCE: AN SSSR. Dolclady*, v. 156, no. 2, 1964o '457-460 TOPIC TAGS: nitrate reduction, hydrogen peroxide, algae, chlorella, nitrate, ammonia, amination, nitrogen, biosynthesis 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- Card 1/2 ;ACCESSION NR: AP4036729 ed with the assistance of the induced reduction reaction.

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 1 of 2 - 1 - USSR/Solid State Physics - Phase Transformations in Solids..

Tr. Nauchno-tekhn. o-va chernoy metallurgii. Ukr. resp. pravl. , 1956, Vol 4, pp 127-130. Comments, pp 131- 1137 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. 1. Arsenic compounds 2.

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 Card 1/2 at an angle of 2o-35'.

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 Card 1/2 S/032/63/029/003/005/020 Determination of cerium-containing ... B117/Ble6 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.

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: Resonators with Tensorial Media SOV/109-3-12-6/13 rot H iwMCZ +-114 rot iW '9H 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 Resonators with Tensorial Media SOVi09-3-i2-6/13 expressed by: W~ + iW11 Wt + i n n n ~n) 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 em and hm and the functions ~o and q) a-re to be 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.

Seriya fizicheskaya, 1959, Vol 23, Nr 3, PP 361-371 (USSR) ABSTRACT: The work under review deals with magnetized materials which are used in practice. To begin with, the properties of ferro- magnetic semiconductors were investigated in small alternating fields in the range of superhigh frequencies. Tensor character and ferromagnetic resonance of the semiconductor are the mostv important characteristic features of the magnetic susceptibil- ity T. Figure 1 shows the components of the tensor of magnetic susceptibility of a polycrystalline ferroma~,-netic semiconductor.

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 Card 2/4 the coarsest (least accurate) are used at the present- time.

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:,. In the case of low frequencies the ranges of natural roso- nance and the resonance in the external field ovt~rlap 0,'ii; 4). This-is the reason why semiconductors with small an.1z:ot-ropy and saturation magnetization were developed for the l3n-S-,7e_7e range.

G. 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 res Card 1/7 89271 9/181/61/003/001/003/042 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 89271 S1181 61/003/001/003/042 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 thank Professor P. A. Smolenskiy for discussions; F. M. Samigullin participated in measurements.
