TL;DR: In this article, the authors derived an expression for the height equivalent to a theoretical plate (HETP), h, of a tubular column of radius r: where: v = average carrier gas velocity; Dg = molecular diffusion coefficient of component in the gas phase; Dl = molecular diffusing coefficient of components in the liquid phase; k = capacity ratio of liquid over gas phase.
Abstract: IN a former publication1 the following expression was derived for the height equivalent to a theoretical plate (HETP), h, of a tubular column of radius r: where: v = average carrier gas velocity; Dg = molecular diffusion coefficient of component in the gas phase; Dl = molecular diffusion coefficient of component in the liquid phase; k = capacity ratio of liquid over gas phase; r = radius of tubular column; K = partition coefficient.

TL;DR: In this paper, the height-equivalent to a theoretical plate of a chromatographic column, either packed or tubular, can be represented by the general equation: where v designates the carrier gas velocity, Dg and Dl the diffusion coefficients of the particular component considered in the carrier gases and in the fixed phase, respectively, and where A, B, Cg and Cl are appropriate constants (A = 0 in tubular columns).

TL;DR: In this paper, a method of coding open-ended carbon chains was suggested, which amounted, in effect, to forming the autocorrelation function of the net, and this code had the advantage of being nearly unambiguous, but suffered from the drawback that, while the code of any given net could be determined straightforwardly, the net corresponding to a given code could not.
Abstract: IN a previous communication1, a method of coding open-ended carbon chains was suggested, which amounted, in effect, to forming the autocorrelation function of the net. This code had the advantage of being nearly unambiguous, but suffered from the drawback that, while the code of any given net could be determined straightforwardly, the net corresponding to a given code could not. A. Savitzky has suggested (private communication) that, nevertheless, this code could be useful as a check; that is, if added to the usual chemical name of a given compound, this code could serve to verify whether the topology of the compound reconstructed from the name is the correct one.
