Conditional Stability Constants

2012
The introduction of conditional stability constants permits us, from a theoretical standpoint, to treat a complexation equilibrium to which are superimposed other equilibria of any nature as if it were alone, at least in some conditions. Conditional stability constants were introduced by G.

On an Absolute Constant in the Theory of Variational Stability

American Journal of Mathematics, 1937
this equation being the characteristic equation of a real binary linear substitution of determinant 1. If A is not a multiple of Tiri, it is clear that the two solutions (2) are linearly independent. If X is a multiple of Tiri, it depends on the elementary divisors of that binary substitution whether or not the general solution of (1) is free of ...

Stability constants of some metal dithizonates

Talanta, 1973
The overall stability constants of electroneutral dithizonates of bismuth, cadmium, cobalt(II), copper(II), iron(II), lead(II), manganese(II), mercury(II), nickel, palladium(II), silver, tin(II) and zinc were determined by means of stoichiometric dilution in aqueous solution stabilized by hydroxylamine hydrochloride, at pH 5.50-10.02.

Determination of the Stability Constants of Tetracycline Complexes

Journal of Pharmaceutical Sciences, 1965
The Bjerrum ΔKOH method for determining the degree of formation ( n ¯ ) from the titration curves of a ligand with and without metals is derived without approximations. The Calvin and Wilson method is rederived in a form which allows easy comparison between the values calculated by each method.

The stability constants of TAR and PAR complexes

Talanta, 1967
A discussion is given of the problem of ascribing dissociation constants in the hypothetical situation in which the protons of the hydroxy groups of TAR and PAR dissociate in the reverse of the normal order, and it is suggested that the o-hydroxy group should be regarded as intrinsically as acidic as the p-hydroxy group, and that the change in pK due ...

Constant gain stabilization with desired damping

Computers & Chemical Engineering, 2006
In this short note, we have proposed an approach to find the solution for constant gain stabilization problem with desired damping. This short note illustrates that it is easy to find the bound on the constant gain as compared to Aniruddha Datta's proposed method.

Self-Stabilizing Symmetry Breaking in Constant Space

SIAM Journal on Computing, 2002
Summary: We investigate the problem of self-stabilizing round-robin token management on a bidirectional ring of identical processors. Each processor is an asynchronous probabilistic finite state (i.e., constant space) machine which sends and receives constant-size messages and whose state transition is triggered by the receipt of a message.

Potentiometric determination of aminal stability constants

Talanta, 1995
Potentiometric titration was used to determine the logarithms of the stepwise equilibrium constants for the species formed between morpholine and formaldehyde in aqueous solution, ionic strength 0.5 and 2.5M (KCl) at 25 degrees C. The instrumental and computational techniques developed for metal-ligand stability constant determination were applied ...

Constants of the Motion and Microscopic Stability of Plasmas

The Physics of Fluids, 1967
The possibility of sidestepping the direct solution of the Vlasov equation in order to obtain information about the stability of a plasma by employing certain constants of the motion is discussed. For plane equilibria a large set of conservation laws is derived in the electrostatic approximation, including those for the total energy and momentum of the
