At the same time it is Dresumed that the influence exercised by the physical structure of the zinc can be eliminated by investigating the dissolving velocities of the individual faons of the monocrystals of zinc. In the present paper the Card 1/4 authors tell of results which they obtained when investigating _tp gr qqju~jon arid.. of. the Solubi1ity Potential/ 8/17 Tho Otpdy,'cif tb!kj~j la Acid. in H~drochiorla and SiLlphur II.The Rate of Solution of I'Jonocrystalline Zinc the dissolving velocity of the basic face 0001 of mono- crystals of very pure zinc in the acids (RC1 and H 2s0 4 ). The method was in principle identical with that described by ref. I (both works were completed in 1949). Results: 1.) Monocrystals were obtained from very pure zinc (99,9999 atomic zinc 4a) and the possibilities for applying the methods developed by Paliban and Proyman were described. 2.) The velocity of the self-dissolution of the basic face 0001 of the monocrystals of zinc in hydrochloric- nnd sulphuric acid and their steady potentials were investiga- ted. It was shown that the dependence of the velocity of self-dissolution on the concentration of the acid is of exponential character in the case of hydrochloric acid. In the case of sulphuric acid it is nearly linear. The steady potential of the self-dissolving monocrystals of zinc shifts in a negative direction in hydrochloric acid, and in sulphuric acid it varies only within the error limits. Card 2/4 3.)

It was shown that Taix the solution exercises a considerable influence upon the velocity of self-diesolution of the zinc, which is, however, considerably lower than in the case of a diffuse dissolution of magnesium in acids. 5.) A comparison was drawn between the relative velocities WZn; WCr; WKn Hg; W~,,n PO W computed. It wis shown that the interrelations between these amounts, as also the dependence of the steady potential of zinc and cadmium on the concentration of the hydrochloric acid can be explained on the basis of the kinetics of electrode processes in concentrated acid solu- tions. The influence exercised by the specific anion adsorption and the formation of complexes between the anions of the acid and the ions of the metal upon these processes in the solution is taken into account.

This method permits study of the content and renewal rate of various phospholipid fractions under normal and hypoxic conditions. Male white rate weighing 180-240 g were subcutaneously injected with radioactive phosphate (Na2 Hp3204) in a dose of 5 ucu per g. I=ediately afterwards,- tNe rats vere placed in a pressure chamber, where they "ascended to 9000 m" (240 mm Hg), They were decapitated two hours after the beginning of the experiment, and lipids were extra,:ted from their cerebral hemispheres. One mt of concentrated extract vaB used for fractionation. An index of "relative specific radioactivity" C-ld 1/3 - - L 1337-66 ACCESSION NR: AP5021236 was used to deteradne the renewal rate of phospholipids and phospholipid fractions.' Experimental results showed that, under normal conditions, fractions of phosphatide acids -and phosphoinositidas (phosphatidyl inasitols) are renewed significantly faster than the remaining fractions (lecithins, sphingomyelins, and amine-containing phospholipids (phosphatidylethanolamine and lysophosphatidyier-hanolaminel). This :Jt~'Ien~e Is apparently connected with the chemical structurv of different phos- groups, and with differences in thei- biosynthesis. it was foLmd that hypoxia does not change the content of the phospholipid fractions studied, but It definitely lowers the metabolic intensity of the phosphate groups in all fractions.!, A clear difference was established in the degree of lowering of the metabolic intensity of different fractions under h-ypoxic conditions. It was concluded that different enzyme systems catalyzing different biosynthetic reactions of various phospholipids are depressed to a different degree under hypoxic conditions. The greatest decrease in metabolism was observed in amine-containing phospholipids and ia lecIthin fractions, and the least in phosphatide ar-id fractions. Orig. art. has: 3 figures.

Male white rats were kept in a pressure chamber for 110 min at'a pressure of 200-180 mm Hg (equivalent to an altitude of 10,000-to 11,000 m). Radioactive phosphate inJections (5 uCu/9) were administered before and after hypoxia, and then at intervals of 2, 4, and 6 hr. Phospholipids extracted from the brain of killed animals were fractionated on silica gel columns. The relative specific radioactivity (RSR) of phosphate groups in each fraction was used as a meass- ure of their renewal rate. It was found that a 2-hr stay in the pressure chamber caused a variable suppression of RSR for individual fractions: It decreased least Card ACC NRt AP5028884 C7 i'or phosphatide acids and polyglycerophosphatides, more for amine-containing phos- pholipids and sphingomyelins, and most for phosphoinositides and lecithins. Post- 1 hypoxic recovery of metabolic intensity was also different for different fractions. The most rapid recovery was observed in fraction 11, the amine-containing phospholip- ids "pho5phatidylethanolamines and phosphatidylserines,'. A retarded recovery of RSR was observed in che lecithin and sphingomyelin fractions. Tt is Suggested that the observed characteristics of brain-tissue phospholipid metabolism in hypoxic conditionE may be connected w-ith the varying sensitivity to hypoxia of enzyme catalyzing biosyn- thesis reactions in the individual phospholipids.

Arkt. i antarkt. n.-i. in-ta, 210, 1961, 35-37) TEXT: The Institut okeanologii AN SSSR (Institute of Oceanology, Acadepy of Sciences, USSR) employed a cr-5's, (SG-55) depth self- recorder, and the Arkticheskiy i antarkticheakiy institut (Arctic and Antarctic Institute) used a depth autograph, in order to ob- tain reliable values for the deepening of the carrier buoy on cur- ~ent self-recorders in autonomous erections. The sinking depth, is determined by the depth autograph from the magnitude of tho procaure of a oolumn of wat* upon a hydrostat. The hydrostat's data are recorded on the tape of an hourly mechanism roller. A -:-depth of down to 150 m can be measured by the autograph# with a Card 1/2 S/169,/62/000/004/044/103 Determining the sinking ... D228/D302 recording duration of about 4 hours (it is possible to fix a week- ly starter to the instruments). The depth autographs were tested in 1958 in the Kara Sea. The horizon of the instrument's sinking was ascertained by means of a block-counter. A table was compiled and a calibration graph was constructed, from the collation re- sults. The depth self-recorder was suspended on the carrier buoy and placed in the water for up to 24 days. The results are cited for determining the sinking depth of the current self-recorders by means of the depth autograph. It is shown that the actual depth of the current self-recorder's installation can differ from the calculated by 4 - 5 m. The magnitude of the depression of the buoy with the instrument does not exceed 0.6 m during the work of an autonomous station,, /-Abstracter's note: Complete tranBlationo-7 Card 2/2 I,,DVORK IN., . ~e.N.

TITLE: Vacuum thermal method for obtaining titanium silicides -)7 ISOURCE: Zhurnal prlkladnoy khtmii, v. 38, no. 8, 1965, 1716-1725 TOPIC TAGS: titanium compound, silicide, vacuum furnace I IABSTRACT: The article describes the results of an investigation of conditions necessary for obtaining silicide phases of titanium. Starting materials were ~Jsilicon (99,916) and titanium dioxide (W. 01o). The titanium dioxide was previously calcined in a muffle furnace ~t_ _900- 1*0 C to eliminate volatile contaminants and moisture. Experiments on the reduction of titanium dioxide with silicon with the formation of the silicide phases were carried out in a vacuum furnace at a temperi- ature of 1200-2100 K under a vacuum on the order of 10-2 -_10-4 mm Hg. After reduction, the samples were subjected to chemical and X-ray phase analysis. X-ray photos showed that up to 1500 K titanium dioxide is reduced to the lower Card 1 / 2 L1613-66 ACCESSION NR: AP5021663 oxides, while at 1500-1550 C there appear lines of a higher titanium silicide, At 1600-1650 K, the silicon and all of the reduced titanium are completely bound in titanium disilicide. The following state, which proceeds fastest at 1720-1780KI leads to reduction of titanium oxide and penetration of the reduced titanium into the disilicide, with interlocking of its lattice into the lattice of titanium monosili- cide. Further increase in temperature leads to an acceleration of the reaction leading to the formation of Ti5S3. At a vacuum of 10- 2-10- 3 mm Hg, Ti5S3 forms at a temperature of 1800- 1900 K. The following optimum operating condi- tions are recommended for obtaining titanium silicides by this method: Ti5S -- 1800-1900 C, residence time I hour; TiSi--1750-1800 K, residence time 1. 5-1 hours; TiS2--1650-1700 K, residence time 1-1. 5 hours, Recommended depth of vacuum is identical for ancases --10-3--1o-4 mm Hg.

Simultaneous measurements of these meteorological elements were made from boats and floats once or twice per month during the navigation season (generally, two"or three points on the water and one on each bank). Each seriez included measurements lasting 1.5-3 hr with instruments (aspirated psychrometers and hand anemometers) 2 m above L 06546-67 ACC NR3 AT6021515 the surface, It was found that changes in these meteorological elements over the reservoir had a rather definite relationship to the stratifica- tion of the air in the bottom 2-m layer. -.Considerable changes in elements were noted in the spring and first half of the summer (period of inversions), such as a drop "iof 5-6C in air temperatures over the water; little or no increase in humidity was observed over the water du,rinrt. inversions, o.r--l.ow-te.mp era tur as in the sprinp.
