Labview VIs based upon the calculator programs of Fabiato and Fabiato (J. Physiol. Paris 75 (1979) 463) are presented. The VIs comprise the necessary computations for the accurate preparation of multiple-metal buffers, for the back-calculation of buffer composition given known free metal concentrations and stability constants used, for the determination of free concentrations from a given buffe...

The stability constants and enthalpies of formation of silver (I) complexes with histidine and imidazole were determined. Two types of complexes were found: AgL and AgL+2 . The second is much more stable that is evidenced by the higher stability constants and enthalpies of formation. For the two systems, the respective constants and enthalpies are very close one to another that suggests similar...

We consider the two-dimensional Landau-de Gennes energy with several elastic constants, subject to general k-radially symmetric boundary conditions. We show that for generic elastic constants the critical points consistent with the symmetry of the boundary conditions exist only in the case k = 2. In this case we identify three types of radial profiles: with two, three of full five components an...

A recent proposal (Clin Chem 1992;38:1809-18) that inorganic phosphate is the predominant small molecule binding Al3+ in blood serum is shown to be incorrect. Experiments in which Al3+ is added to solutions containing phosphate and citrate in the same proportions as in serum clearly show that citrate prevents formation of any aluminum phosphate precipitate, and analysis of these data indicates ...

the determination of formation constants of binary inner transition metal complexes where m=y(iii) or la(iii) or ce(iii) or pr(iii) or nd(iii) or sm (iii) or gd (iii) or dy (iii) or th(iv) andl = creatinine have been carried out using irving–rossotti titration technique in aqueous mediaat different temperatures and at ionic strength. to understand more about the nature ofequilibrium involving i...

Optimal stability polynomials are polynomials whose stability region is as large as possible in a certain region, here the real-negative axis. We are interested in such polynomials wich in addition, obey a certain order condition. An important application of these polynomials is the construction of stabilized explicit Runge-Kutta methods (see 6] for a survey article and 4]). In this paper we wi...

All the published stability constants of cyanocomplexes of metal ions, and the acidic dissociation constants of hydrogen cyanide, and those of the protonated metal complexes are critically surveyed. Unfortunately, a great fraction of data is unreliable and only a few thermodynamic data could be classified to the category of recommended values. The reasons of this situation are thorougly treated...

We prove that L∞-norming sets for finite-dimensional multivariate function spaces on compact sets are stable under small perturbations. This implies stability of interpolation operator norms (Lebesgue constants), in spaces of algebraic and trigonometric polynomials. 2010 AMS subject classification: 41A10, 41A63, 42A15, 65D05.
