Determination of maximum complexing ability of water-soluble complexants
(The Williams & Wilkins Co., 1972)
When the maximum complexing ability (MCA) of water-soluble complexants of unknown molecular weight is known, it is possible to calculate the stability constants of metal complexes where these complexants participate (2,4,5). ...
Cities and methods from complexity science
(Springer, 2016-05)
The dynamics of human society is now been studying in the context of the artificial environment created by cities. In this work, the authors describe some of the formal methods used in complexity science to study urban ...

Characteristics, complexation and analytical methods of darunavir
(2014)
What is it? Darunavir is a protease inhibitor used in the treatment of HIV infection. It is an important drug of therapy cocktail for patients infected with the virus. On the market there are darunavir ethanolate tablets ...
A complex dynamical approach of Chebyshev’s method
The aim of this paper is to investigate the iterative root-finding Chebyshev’s method from a dynamical perspective. We analyze the behavior of the method applied to low degree polynomials. In this work we focus on the ...
On the design and analysis of high order Weerakoon-Fernando methods based on weight functions
In this article, using the idea of weight functions on Weerakoon‐Fernando's method, an optimal fourth‐order method and some higher order multipoint methods for solving nonlinear equations are proposed. These methods are ...
The Wilkinson Complex as a heterogeneous catalyst in the partial hydrogenation of 1-heptyne. regeneration of the complex
(Sociedade Brasileira de Química, 2016-06)
The Wilkinson complex was tested as a catalyst in the partial hydrogenation of 1-heptyne, a medium chain alkyne, at a temperature of T = 303 K and hydrogen pressure PH2 = 150 kPa. The tests were performed in homogeneous ...
On the complexity of computing estimates of condition measures of a conic linear system
(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 2003)
Condition numbers based on the "distance to ill-posedness" rho(d) have been shown to play a crucial role in the theoretical complexity of solving convex optimization models. In this paper, we present two algorithms and ...
Integrated X-ray crystallography, optical and computational methods in studies of structure and luminescence of new synthesized complexes of lanthanides with ligands derived from 2,6-diformylpyridine
(2011-03-24)
The reaction of 2,6-diformylpyridine-bis(benzoylhydrazone) [dfpbbh] and 2,6-diformylpyridine-bis(4-phenylsemicarbazone) [dfpbpsc] with lanthanides salts yielded the new chelates complexes [Eu(dfpbpsc-H +) 2]NO 3 (1), ...
