Square-integrability of solutions of the Yamabe equation [PDF]

open access: yes, 2011
We show that solutions of the Yamabe equation on certain n- dimensional non-compact Riemannian manifolds which are bounded and Lp for p = 2n=(n-2) are also L2. This Lp-L2-implication provides explicit constants in the surgery-monotonicity formula for the

Thermodynamics of the complexation between salicylaldehyde thiosemicarbazone with Cu2+ ion in methanol +1,4-dioxane binary solutions [PDF]

open access: yesJournal of the Serbian Chemical Society, 2014
The complexation reaction between salicylaldehyde thiosemicarbazone, abbreviated as STSC, with Cu2+ ion was studied in the binary mixtures of methanol + 1,4-dioxane binary by using UV-Visible spectrophotometric and conductometric methods at ...

Determination and stability constants of Manganese (II) amino acid complexes [PDF]

open access: yes, 2011
The stepwise and the overall stability constants of the complexes formed by manganese (II) ion and twelve (12) amino acids have been determined. The dissociation constants, pKa, of the amino acids determined are; alanine (10.29), arginine (12.02 ...

Stability of the Poincaré constant

open access: yesBernoulli, 2023
The article studies stability of the best constant in the Poincaré inequality for the invariant distribution of a reversible diffusion on a smooth manifold. That is, it provides a lower bound for the best constant for a probability measure on the manifold satisfying the Poincaré inequality, in terms of the Wasserstein-1 distance between the push ...

Leucine Complexes with Cerium: Stability Constants and Thermodynamic Parameters [PDF]

open access: yes, 2011
The complexation of leucine (Leu) with Ce3+ was investigated using the potentiometric method at different ionic strengths (I = (0.10 and 1.00) mol dm(-3)) in KCl medium at elevated temperatures.

Potentiometeric Study of New Schiff Base Complexes Bearing Morpholine in Ethanol-water Medium with some Metal Ions

open access: yesInternational Journal of Electrochemical Science, 2019
Acid dissociation constants of 2-[(4-morpholinobenzylidene)amino]phenol (HL) and the equilibrium constants of their metal complexes with Cu2+, Zn2+, Sr2+, Cd2+, Ba2+ and Hg2+ ions were investigated using a pH metric titration technique in 40 % (v/v ...

A COMPARATIVE EVALUATION OF THE STABILITY OF APPLE ACID COMPLEXES AND SOYA OIL PHOSPHOLIPIDS WITH IRON AND COPPER IONS

open access: yesНовые технологии, 2020
The effectiveness of hydration, which is the first stage of refining vegetable oils, depends primarily on the ability of the hydrating agent to convert nonhydratable phospholipids into their hydratable forms.

The Effect of Metal Cations on the Aqueous Behavior of Dopamine. Thermodynamic Investigation of the Binary and Ternary Interactions with Cd2+, Cu2+ and UO22+ in NaCl at Different Ionic Strengths and Temperatures

open access: yesMolecules, 2021
The interactions of dopamine [2-(3,4-Dihydroxyphenyl)ethylamine, (Dop−)] with cadmium(II), copper(II) and uranyl(VI) were studied in NaCl(aq) at different ionic strengths (0 ≤ I/mol dm−3 ≤ 1.0) and temperatures (288.15 ≤ T/K ≤ 318.15).

Lectures on Stability and Constant Scalar Curvature [PDF]

open access: yesCurrent Developments in Mathematics, 2007
An introduction is provided to some current research trends in stability in geometric invariant theory and the problem of Kaehler metrics of constant scalar curvature. Besides classical notions such as Chow-Mumford stability, the emphasis is on several new stability conditions, such as K-stability, Donaldson's infinite-dimensional GIT, and conditions ...
