Ace- tylcholine is contained in synaptic 'vesicles situated near the presynaptic membrane. Quanta of the compound are secreted spontaneously in the absence of nerve impulses. The number of quanta released by nerve impulses can be determined. from the formula m = Pn, where m. is the quantal composition of end-plate potential, P is the mean probability of release of a quantum, and n is the supply of acetylcholine available for immediate release. The prob- ability of transmitter release at the mamma.-Iian neuromuscular. junction is determined by two main factors: level of membrane.potential of the nerve endings and concentration of calcium ions "in the external medium. The probability is much greater with inAuced than spontanc., b release. The nature Ou 1/2 USSR KAMENSKAYA, M.

The presence of 0.005, 0.017, and 0.26% B decreases the concentration of C from 69 to 28 atomic % and increases the concentration of Cr from, 8 to 51 atomic Z. This decrease.,, the concentration Of M23C6 in steel and -increases the amount of Cr in borides. Evidently part of C in ~123C6 becomes substi- tuted with B.

Bochkareva). Translation: Specimens of 40Kh steel were subjected to the following heat treatment: hardening (heating to 850 IS* in a Pb bath, cooling in oil); low temperature tempering (heating in a salt bath at 220 � 10% cooling in water) to produce "hard" specimens; high temperature tempering (heating in a saltpeter bath at SOO � 10% cooling in water) to produce I'soft" speci- mens.. It is shown that repeated high energy impacts greatly reduce the strength of the "soft" and "hard" specimens, while low energy impacts increase strength. It is established that the maximum number of impacts can be with- stood by specimens of "soft" metal, which have hish~plasticity and low hard- ness, followed by the steel as delivered rolled, then the "hard" specimens, and finally, the hardened specimens without tempering.

As a distinguishing feature of thepatent, in order to autor-atc. elimirlatior of interference, simplify equipment and process the recording, the potential difference is measured at three times separated by int(--!rvals, of no more than one second. The first two measure-ments are made befor,_-,~ the currcnlu is fed into the growid, and the 'third ir, mado after introducinj~ Lbe curruiflu, iritc, the ground. Ine sought potential difference is determined from the measured. values. ............. USSR ur)c 621-375.8,26 UY Ye. I., KOZLOV, V. V. "Lasers With Polyhed-ral Energy Guide" Moscow, Kvantovaya Elektronika, Sbornik, St tey, No 4, "Sovetskoye Radio", 1971, PP 77-86 Abstract: New types of cavities are proposed for lasers and laser ampli- fiers -- energy guides in irhicb the overall, dimensions are kept sr2all while providing a long path of interaction betw*een the emission and the act.ivo material. The proposed design reduces overall dimensions, and improves the operationU reliability and paraneters of laser sypter.=. A me"bod is developed for designing the energy guides, examples are- given to illus- trate the design of such caNrities, a description is given of a polyhedral energy guide made of neodymium glass, &,id the results of pre-liminary ex- periments are presented. It is sho,.m that the new minitiLure laser cavity provides an active erid-ssion path up to 2.5 meters long while reducing the artivation threshold, inproving the mode :structure and ninimizing laser bean divergence.

Radio", 1971, pp 77-86 ment of flash tubes Drovide efficient utilization of optically stimulated emission, in addition to low electric thresholds. The long optical path improves transverse mode selectivity and provides peakless emission at energy levels exceeding thethreshold pumping enerb-r by a factor of 1.5. The improvement in transverse mode selectivity without addinj~ optic--! equipment provides the possibility of stable emission on a single trans- verse mode and concentration of the emission an angle close to the diffraction limit.

Moscow, Prikladnaya Hatematika. i Mekhanilca, No 2, 1972, pp 320-329 Abstract; Strong discontinuities, differing from elastic shock ww4es, can originate in elastoplastic media; this brings! necessity for seeking additional conditions on shocks. It would be desirable to isolate media for which solutions can be constructed without the use of such d-4--continui ties. It has been qhoini that: with the Mii3es condition of planticity and with Iso- tropic strengthening, two velocity comp-onents and sora! in the presence of limitations upon the initial stressed state, simple p.l.ane waves do not over- turn. This is valid for inedia with a FAress-deformation diagram convel: to the stress axis for an experiment on simple compression. lu the present article, this statement is generalized for the case of arbitrary simple plane waves in the same medium. The solution'of the problern of the disintegration of an arbitrary discontinuity is constructed Ldth more rigo-rous conditions. In this case, no shocks exist except elastic shock waves, contact discoritinu- ities, and shocks which are the limit case of simple waves pyopagating at constant velocity. 4 figures. 7 references, 112 015 UNCLASSIFItb~ PROCE~SING DATE--160CT70 '.rITLE--LOW LYING ONE PHONON OPLUS LEVELS'IN SPHERICAL NUCLEI -U- :,AUTHOR--KAMER0ZHIYEVt S.P, OF- INFO_-USSR .,.SOURCE-YAD.
