AUTHORS: '~ogan ,V. S., Laz-.rev, B. G., 7.ulatova, R. P. 56-1-42/56 TTTLE: On the Phase Diagram of the System Hydrogen - Deuterium (0 diagramme sostoyaniya sistemy Yodorod-deyterij) PERIODICAL: Zhurnal Eksperimentallnoy i Teoretichesko.v Fiziki, 1958, Vol. 34, Nr 1, pp. 236-24o (USSR) ABSTRACT: At first ref(.~rence is made to papers dealing with the same suject. In the Con-ress on Physics of Loy., Temperatures held in June 1956 in LeninL;rad reports were also made on the results of inveetigations of the cryBtal-otructure of the mixtures of hydrogen-isotopes. The solid solutions in such a system only exist in limited domains of concentration. The present paper gives more accurate data on this system which wore obtained on the basis of the thermal analysis of the hydrogen-deuterium mixtures. The mixtures pro-,uced of pure isotopes wcre condensed in a calorimeter immersed in liquid hydrogen. After the evacuation the mixture was slowly heated in t2he temperature interval 14 - 1)10C. The thermal analysis showed a horizontal part on the nolidus curve at 1694 0K. By a comparison of tho data of the thermal analysis with t~~e results of the X-ray photographs at a temperature of 4,2 0K Card 1/3 the approximate bolindaries of the domain of the separation On the Phase Diairam of the System Hydrogen - Deuterium 56-1-42/56 in layers c~,uld be determined and the phase dial am hydrogen- ,r -deuterium in general could be outlined. The existence of the peritectic surface in crystallizutions of the ,iixtures at concentrations of frim 26 to 57 per c,nt by volune of h-drogen was visually verified. In parallel wiV. the thermal analysis the X-ray structure inve,,;tigations of the hydro,-,en- -deuterium mixtures and of the pure isitopes were continued. A certain perfection of the method- of photographing permitted the removal of the parasitic lines. The ro,-.t,-,--enoGrams contain 2 hydrojen-lines which correszond to the distances d - 3,_15 X an,4 d - 2,79 X between the planes. Of the deuteriu-i-lattice only one line with d ~2,'_4 A exists. Due to the hi-h decrease of the intensity of scattcrin:- no lines exist under 1,.rg(- angriec. There exists a concentration ranL-le in which the solid. mixtires of h.-drogen and deuterium tre ttro-phase. The problem of the exact structure of hydrogen and deuterium still remains unsolved. In any case the lattices of hydrogen and deuterium are different. The results obtained here indicate a separation in 1,-.yers in the solid mixtures of th!: hydrogen isotopes ane. corresponi to the conclusions drawn by Prigozhin (reference 3) on the existeice Card 2/3 of' a critical temperiture, belo,.,v i,.hicli the isotope mixtures .On the Phase Diagram of the System Hydrogen - Deuterium 56-1-42/56 must split up in layers.

TITLE: Diffraction of X-Rays in Pc~lyorystalline Samples of Hydrogen Isotopea PERIODICAL: Zhurnal eksperimentallnoy i teoreticheakoy fiziki,, 1959, vol 37, Nr 3 (9)9 pp 678-683 (USSR) ABSTRACT: The authors already showed (Ref 1) that the diffraction picture of X-rays on polycrystalline samples of hydrogen, deuterium, and their mixtures depends on the isotope composition of the sample. In this connection the au.+hors believed an investigation of tritium (which is similar to deuterium as regards weight, but to hydrogen with respect to the energy speotrum - half-integral spin to be of interest. In fiLruxe 1 the experimental arrangementq in which the X-ray pictures of the solid samples of hydrogen isotopes were reoorded~ are shown and discussed. Figure 2 shows the tritium X-ray pizture (copper lines were used as comparison standards) and figuxa 3 the X-ray pichures of D 2 and 11~. A comparison of the interferenoe patterns indicates the existence Card 1/3 of isotopic polymorphism. The differenca in the strwaturs of Diffraction of X-Rays in PolyeTystalline Samplea of SOV/56-37-3-15/62 Hydrogen Isotopes hydrogen and deuterium and the s1milarity of the structure of the latter to that of tritium shows that the polymorphism is not due to a difference in the sne3~gy spa~tra but to a differenoe in the atomi-- weight.

TITLE: Crystal Structure of Solid Deuterium PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1960, Vol. 39, No. 6(12), p. 1853 TEXT: Previous studies (Refs. 1,2) have shown that H 2 and D2 have a tetragonal, body-centered lattice with c/a = 0.82 and c/a = 1.73, respectively. Tritium has the same structure as deuterium. The crystal structure of HD has now been studied using the same experimental arrangement as described in Ref. 1, and a brief report thereon is made in this "Letter to the Editor". Like D 2 and H29 HD shows one single 5line- in the X.:-ray diagram. Calculations assigned HD to the space group C 4 (tetragonal and body-centered). a = 3.39 A, c = 5.86 A, c/a = 1.73 gave a density of 0.146 g/cm3 at 4.20K. This value is in good agreement with results obtained by other research workers. There are 6 references: 5 Card 1/2 Crystal structure of Solid Deuterium Soviet and 1 US.

TITLE: Differences in the lattice constants of neon isotopes PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, v. 40, no. 1, 1961p 29-31 TEXT: The authors know of.orJy one single case in which the attempt had been made to find differences in the lattice parameters of elements heavier than helium'* on L16 and L17 a difference of 0.0015 A was found to exist, a value which is near the limit of measuring accuracy. Theoretically, the differences of the lattice parameters of the isotopes of noble gases, i.e. the differences of the molar volumina in the solid phase have repeatedly been investigated; for neon, one obtained the followfng at OOK: AV/V - 0.6~o. An experimental study was the purpose of the present pacer. By means of X-ray analysis, the structuresof Ne20 (99% pure) and of Ne 2 (98% pure) were examined. The specimens freed from air and helium impuri- ties, were obtained in form of polycrystalline layers, viz., the neon isotope was precipitated from the gaseous phase onto a copper capillary Card 1/4 S/056/61/040/001/004/037 89199 S/056/61/040/001/004/037 Differences in the lattice ... B102/B204 tube, which was cooled from the inside by means of liquid helium. The experimental arrangement for the X-ray examination of such a specimen is described in Ref. 5. A typical X-ray diagram recorded by means of this device, on which also the Cu lines are visible, is shown in the figure. The X-ray diagrams were photometrized, the distances between the maxima of the interference lines were measured with an accuracy of +0.03-�0.05 mm. The corrections for sample thickness were carried out according to Kurdyumov. The results of the studies are shown in the table; the data of the lattice parameters are accurate up to + 0.004 A. Both isotopes have face-centered cubic lattices; for the light isotope, a = 4-471A , and for the heavy one, a - 4-455 AjAV/V - (1.1+0-5)~o. The line intensities found in the X-ray diagrams deviated considerably from the calculated values. Thus, in Cu - K. and Fe - K. radiations, the intensity of the (200) lines compared with those of the-(*111) lines were considerably lower than calcu- lated, the intensity of the (222) line of the Fe - Ka-radiation was higher. This is explained by the fact that the neon precipitated from the gaseous phase upon the capillary tube has a texture, in which the [111] axis is radially orientated toward the capillary tube. The intensity ratios of the same interference lines - I hkl (,1e 22 )/Ihkl (Ne 20) is higher and grows more Card 2/4 S/05.6/61/040/001/004/037 Differences in the lattice ~B102/3204 quickly with increasing sca.ttering angle than would have been theoretically expected. By way of a summary it is said that the'AV/V-value obtained shoea good agreement.with theoretical results considering the energy differences of zero vib'rations.- By far greater differences of the molar volumes of the Ne 'Isotope - compared to the.Li isotopes - are ascribed to the difference in .the-binding forces in the n'eon'and lithium,lattices.

Mechanism of Passive Immunity in Toxinemic Diseases "The Protection of the Central Nervous Systen Against the Action of Perfringens and Oedematiens Toxins In Relation to the Ti,*-.er of Antitoxin in the Blood," by T. I. Bulatova and , Institute of Epidemiology and Mir-roTiology ]~~e e~v imeni.N. F. Gamaleya, Academy of Medical Sciences USSR (direc- tor, Prof S.R. Muromtsev), !~Yulletenl Eksperimentallnoy Biolo ii i Meditsiny, No 3, Mar 57, PP 71-75 The authors..state that "the necessity for an experimental investiga- tion of the! protection of the central nervous system by passive and active immunization against toxinemic infections became absolutely apparent after the appearance of a number of reports by clinicians on the fact, that large doses of immune serum vere capable of curing even severe cases of tetanus, diphtheria, gas gangrene, and botulism." The unsatisfactory results of serotherapy using small doses of serum are felt to be due to the fact that the antibodies do not penetrate through the hematoencephalitic barrier from the blood into the spinal fluid and that the central nervous system is thus inadequately protected by passive im=nity. The article disputes the concept of the hemato- encephalitic barrier which holds that there is an interrelationship between the spinal fluid, the blood, and the central nervous system, i.e., that the exchange between the blood and the central nervous system proceeds through the spinal fluid, and not through blood-carrying capillaries. Instead, it is maintained that "the penetration of various substances into the central nervous system depends not on the composition of the spinal fluid. but on the permeability of blood-ca2-rying capillaries and on the concentration of these substances in the blood." Experiments were carried out on actively and passively imunized rab- bits with perfringens and oedemtiens toxins to determine the effects of intravenous ackinistration of large doses of these toxins on the immuno- logical state of the central nervous system and to see if the animals' central nervous systems acquired resistance to the action of the toxins even when practically no antibodies had penetrated into the spinal fluid. The procedures used in the experiments are described. The results are presented on two charts showing (1) the survival of passively immunized rabbits after suboccipital administration of perfringens and oedematiens toxins and (2) the survival of actively immunized rabbits after suboccipital administration of perfringens and oedematiens toxins. The results showed that the nervous system was better protected against the usual neurotoxic phenomer- elicited by these toxins the higher the titer of antitoxin in the blood. It was found that, the higher the titer of antitoxin in the blood, the more the antibodies penetrated into the brain tissues through the walls of the capillaries, and yet, at the time the antibody content of the brain tissues was highest, there were practi- cally no antibodies in the spinal fluid. Thus these findings corroborated the observations of clinicians that the greater the dose of serum admin- istered in the treatment of gas gangrene the greater was the therapeutic effect obtained.

Zhurnal mikrobiologii, epidemiologii i inmninobiologii, 1960, Nr 3, pp 18 - 22 (USSR) ABSTRAM The aim of subject work was to study the suitability of the fluorescent serum method for detecting the Clostridium botulinum, even in a mixed culture. Fluorescent sera, labeled with fluorescein isocyanate, were prepared from the globulin fraction of botulism antiserum B and were tested with various bacteria. C1. botulinum A and B strains gave off a specific luminescence, particularly bright in the case of the B. strain. No luminescence was observed with Cl. botulinum C and E, Cl.perfringens, Escherichia coli or Bacillus megatherium. In the tests with Cl. sporogenes, three of 17 strains showed specific luminescence, two showed no luminescence and twelve showed individual fluorescing spores against a general background of non-luminescence. All t1_1 luminescent strains agglutinated with botulism antiserum B. No definite relationship could be established between the agglutination Card 1/2 reaction and the intensity of luminescence. The author concludes that SOV/16-60-3-4/37 The Identification of Clostridium Botulinum With Luminescent Sera the fluorescent sera method can only be used as a rough guide in the detection of Cl. botulinum. Further work on the problem is required. There are: 2 tables, 1 photograph and 8 references, 4 of which are Soviet and 4 English.

According to the authors an ideal protective filter should absorb ultraviolet and infrared light and considerably attenuate visible light. The Save - zna komisija za standardizaciju ( Federal Commission for Standardi- zation) has issued under the designation "JUS Z. Bl. 03011 a Yugoslav standard for the "Stitnik za elektrovarioce" (Protector for Electric Welders). This standard prescribes protective measuresfor welders stressing the protection of eyes, head and neck against direct and indirect effects of visible, ultraviolet and infrared lights The standard also gives a table of data on protective filters which are Card 1/10 21917 Y/002/60/000/006/001/001 D251/D301 Optical protective filters for welders built into corresponding protectors. Data deal with the optical thickness of filters for visible 'Light, differentiating between the minimum, maximum and the standard thickness.- Thus, for example, for electric welding-by currents of 30 to 75 amp, a minimum optical thickness of 2.36:to 2.79, a standard optical thickness of 2.572 to 3.000 and a maximum optical thickness of 2.78 to 3.21 are prescribed for visible light. Filters with the optical thickness within cor- responding limits are marked with "shadow numbers" and are so sold. The standard table also gives data on transmission ( in %) of the total visible light, again differentiating between the minimum stand- ard and the maximum transmission. Further, data are given on the permitted maximum transmission of the total infrared and ultraviolet light for the following wavelengths: 313 mi-. , 334 365 m,.,. and 405 m,,.. All these data are given for 12 types of protective filters with the "shadow numbers" from 3 to 14. According to the Yugoslav standard a protective filter with a "shadow number" of 7 will have a minimum optical thickness for visible light of 2.36. By employing Card 2/10 21917 Y/002/60/000/006/001/001 D251/D301 Optical protective filters for welders E = log Jo - log J (1), derived from Lambert's law, and where E the optical thickness of extinction, Jo = light intensity entering the filter, and J = light intensity passing through the filter, it can be computed that this filter will transmit only 0.44% of the total visible light. According to the same standard a protective filter for welders will have a maximum thickness of 5.78 and a cor- responding transmission of visible light of only 0.00017%. Such filters are used in the electric welding by currents of more than 400 amp. As regards the quality control of protective filters, the Yugoslav standard prescribes that every 2 out of the first 100 pieces and 1 out of the further 100 pieces should be checked. The testing of filters, however, is not listed in the standard and the selection of testing methods is left to manufacturers ot establishments con-' .cerned. Optical filters for welders with gelatine layers will have chiefly three components for light absorption, including two com- ponents for the practically total absorption of ultraviolet and in- frared light and one component for attenuating considerably visible Card 3/10 21917 Y/002/60/000/006/001/001 D251/D301 Optical protective filters for welders light. Organic dyes, for example, yellow dyes melted in the gela- tine layer for the absorption of ultraviolet light, are used as com- ponents for absorbing ultraviolet and infrared light. Infrared light is usually well absorbed by salts of some heavy metals such as iron. The attenuation of visible light is carried out differently, but it is always required to attenuate equally the entire spectrum of visible light. For this purpose a "gray" agent of higher concen- tration is added in order to achieve the corresponding high absorp- tion Of Visible light. As "gray" agents for the uniform attenuation of the entire visible light, appropriate black organic dyes or Indi- an ink are also used. Two methods of testing protective filters,i.e. photographic spectral photomet-ry and photometry with photomultipliers are used, The former method ib based on the Reciprocity law - one of the fundamental photochemical laws of photogra hic layers, for- mulated by Jl t1 = J2 t2 = J3 t3 = . . . = const M, where Jl, J2, J3 = the light intensity acting on the photographic layer, and tl, t2, t3 = . = the corresponding values of exposure, which after Card 4/10 ?191-7 Y/002/60/000/006/001/001 Optical protective filters for welders D251/D301 the development produces the same darkening values (D =coiist.),Eq 2 can be applied to determine the optical thickness of filters in the following form: Jo to = J t (2a), where Jo and to = light intensity acting on the photographic layer without filter and exposure, In this case as a light source a "Vitalux" lamp, producing numerous intensive mercury spectral lines with wavelengthsof up to 300 m,-, was used. Pictures were made by the universal "Zeiss" spectrograph, and the "Efka 2011 film of the "Fotokemika" was used as a photonate- rial. Only six spectra are photographed below the scale, including the first four without filter with exposures of 0.1, 0.2, 0,5 and I see, and the last two with a protective filter and exposures of 180 and 115 hours. It is also clear that values used for t are very small and for t very high. The tested protective filtsr had a very high optical thickness, The spectral boundary between vis-.b-;' P. and ultraviolet light is at number 40 on the scale, It is also C~11_ar that the light source has a greater number (about 10) of speciral lines in the ultraviolet region of the spectrum, that is, below 400 M2.1-0 None of these lines is visible in spectra made with the pro- tective filter, meaning that the same filter absorbs so completely Card 5/10 W17 T/002/60/000/006/001/001 D251/D301 optical protective filters for welders that an exposure even of 180 hours has no photochemical effect on the photographic layer. The same is valid for ultraviolet and blue mercury spectral lines with wavelength of 404.7 and 435.8 m.,,, On the contrary, green and yellow mercury spectral lines with wave- lengths of 546.1 and 577.0/579.1 m., pass through the protective fil- ter acting on the photographic layer. As a result of this spectral photograph it can be established that the tested protective filter practically absorbs completely ultraviolet, violet and blue light, and transmits very weak components of green and y ellow light, This spectral photograph further permits the calculatIon of the optical thickness of the protective filter for green light with a wavelength of 579 m~,by using equation 2 a. For this purpose the attenuation (D) of mercury spectral lines in all spectra was photometrically measured, Results obtained are graphically illustrated in Fig, 2, The Reciprocity law cannot be applied to this problem without cor.- responding corrections. A modification of this law known as the Schwarzschild law is expressed by the exponential equation J0 top J tP (3) Card 6/10 2 125 2. ~." Y/'002/60/000/006/001/001 D251/D301 Optical protective filters for welders where p = the Schwarzschild exponent. The application of the photo- graphic method of testing protective filters requires experimental determination of numerical values for the Schwarzschild exponent. In this case, ow-ing to very long exposures, the usual methods of determining the above exponent are faced with constant experimental difficulties, The following method was, therefore, used~ By means of an appropriatephbtomultiplier transmission of the protective filter, to which the spectral photograph refers, was measured for visible light. The photomultiplier had a maximum sensitivity in the green region of the spectrum. By this measurement the following value was obtained J = 0.0281. Values for J were then computed from Eq 3, by using experimental data from the spectral photograph and giving various values to exponent p. Results thus obtained are shown in Table 2 and are also graphically illustrated in the loga- rithmic measure in Fig. 5. A value obtained for the Schwarzschild exponent was p = 0.53. Since homogenous glass protective filters for-welders are not produced in Yugoslavia, the production of filters Card 7/10 21917 Y/002/60/000/006/001/001 D251/D301 Optical protective filters for welders with gelatine layers is to be organized. These layers must be dyed with organic dyes and Indian ink and the filters must be produced ..in accordance with the JUS standard. The above standard gives no method for the optical testing of filters. Only values for the op- tical thickness and light transmission, visible, ultraviolet and infrared, required for certain types of filters, are listed, By means of the spectrographic photograph it was established that fil- ters sufficiently absorb ultraviolet radiation and considerably at- tenuate visible light. By studying results obtained on the basis of the spectrographic photo it was also established that considerably low values of transmission for protective filters are obtained from the equation of the Reciprocity law, The Schwarzachild equation, however, gives good results if the exponent P = 0.53. The photo- multiplier ensures good results for the optical thickness of pro-' tective filters in the visible region of the spectrum. Unlike the spectrographic method which requires very long exposures, over 100 hours, the photomultiplier operates fast. This equipment could also Card 8/10 21)17 Y/002/60/000/006/001/001 D251/D301 Optical protective filters for welders be used for controlling the production of protective filters for welders. Determining the optical thickness of protective filters was impossible in the infrared region of the spectrum. The normal spectral photometers for infrared radiation cannot be used for,this purpose either, owing to the very high optical thickness of filters and a photomultiplier for infrared radiation was not available.
