In this research complexation of dioxovanadium(V) with nitrilotriacetic acid (NTA) at differentionic strengths (0.1 to 1.0 mol dm-3) of sodium perchlorate as supporting electrolyte and pH rangeof 1.00-2.50 at 25 °C has been investigated by a combination of potentiometric and UVspectrophotometric measurements. Stability constants of two species, V0211L- and VO2H2L havebeen calculated. Ionic stre...

Effective dielectric constants of diphase composite dielectrics are simulated by Monte Carlo-finite element method on three-dimensional lattice. Effective dielectric constants with coefficients of variation less than 5.5% are obtained for different ratios of dielectric constants of the two phases, ranging from 10 to 700. Various mixing rules and equations are fitted to these data and the accura...

In this paper we review the basic issues of quantum cosmological models. We explore the Wheeler-DeWitt equation in different contexts but from a dimensional point of view. We end by presenting the Wheeler-DeWitt equation in the case of considering all the constants varying. The quantum potential is obtained and the tunneling probability is studied.

using uv-vis spectrophotometic method, the formation constants for interaction of cd2+(aq) andco2+(aq) ions with l-alanine were experimentally studied at ph = 4.1 ± 0.01 (50mm of potassiumhydrogen phthalate buffer), ionic strength of 0.1m potassium nitrate and at 5 differenttemperatures 15,20, 25,30 and 35°c. the optical absorption spectra of mixtures containingconsidered cations and l-alanine ...

The binding of ligands by a receptor can be expressed in an equation derived by a thermodynamic stoichiometric approach in which the stoichiometric equilibrium constants are all positive and real. An alternative binding equation can be derived algebraically in which the equilibrium constants can have values that are complex numbers. Some consequences of this situation are explored, and numerica...

Methods are described for estimation of kinetic constants from the integrated rate equations for a number of reaction mechanisms. In general, these ( methods depend upon elimination of either zero order or fist order terms between rate curves determined at two initial substrate concentrations or more. This operation is followed by graphic or statistical evaluation of the kinetic constants in th...
