Relationship between physico-chemical properties and local anaesthetic activity NATURWISSENSCRAFTEN1956, 43/13 ( 303-304) Tables I Thirtybasic, ester-substituted, carbamic acid derivatives were investigated for their relationship between local anaesthetic activity and physico- chemical pro- perties. The alkyl, phenyl, tolyl, xylyl, alkoxypherLyl and naphthyl derivatives were studied. Sixteen of the compounds investigated had local anaesthetic activity, 14 did not. Surface, infiltration, and conduction anaesthetic activity was compared with surface activity in buffered and nort-buffered solutions, absorbability. lipoid solubility and ability to flocculate colloids. Relatively good, but not quantita- tive correlation was found between local anaesthetic activity and the above phys- ico-chemical properties. The correlation between surface and infiltration anaes- thetic activity and physico-chemical properties was better than the relationship between conduction anaesthesia and physico-chernical properties. The correlation coefficients ranged from 0.6 to 0.9. Foldes - Pittsburgh, Pa. CZECHOSLOVAkIA Chemical Technology. Drugs. Vitamins. Anti- H biotics. Abs Jour: Ref Zhur-Khimiya, No 22, 1958, 74959.

From this general problem the author singles out the special case of parallel plane walls, which have a certain distance. This corresponds exactly to the exhaust out of the so-called borde nozzle . It can be shown that in this special case simplified formulas for the calculation of the jet contraction can be derived. Also the form of the free Jet after the separation can be calculated. The results are pre- sented in tables. The considered case is mathematically distinguisched by the occurrence of singularities during the determination of the equation of the free jet. Therefore the velocity potential must be determined at first, then the data of the free jet can be calculated.

By using the method of Lindstedt-Poincar6 'Arom celestial mechanics, this problem is solved by means of Lagrange variables, a, b, and t. If ~(a., b, t) and J(a, b, t) are the deviations of the liquid particles from their coordinates a, b at the beginning of motion, the following set of equations is valid for the determination of these deviations: Card 1/3 85522 The Cauchy-Poisson Problem for Finite- S/020/60/133/0()3/024/031/XX amplitude Waves B019/BO67 a2~/at2 = -aH/aa + D(j; H)/D(a, b) a2 at2 ' -all/6b - D(I, H)/D(a,, b) d~~aa + d /3b D(~;-j)/D(a, b),' where ff - (p/Q) + g(b - -q); p - hy rodynamic pressure, and Q = density, For the initial velocity potential the following ansatz is made 00 T(a,b) Y:F nAn enb cos na from which the coefficients of the series n=1 2 2 1 2 + E~I + F_ ~2+ H - F-H1 + 2H*> + I I I. may be computed,.
