Modeling the sorption kinetic of metsulfuron-methyl on Andisols and Ultisols volcanic ash-derived soils: Kinetics parameters and solute transport mechanisms
(2010)
Metsulfuron-methyl sorption kinetic was studied in Andisol and Ultisol soils in view of their distinctive physical and chemical properties: acidic pH and variable surface charge. Different kinetic models were applied to ...
Modified local exchange and kinetic energy functionals for atomic systems
(Elsevier, 1997)
New local functionals for the kinetic and Hartree-Fock exchange energy of atoms are proposed. They are of the following general form: T[ρ] =22/3CF ∫ ∑σρ5/3 σf(r,ρ σ)dr. The function f(r,ρσ), except for two adjustable ...
A kinetics analysis applied to the recovery of Zn(II) content from mine drainage by using a surfactant liquid membrane
(Taylor and Francis Inc., 2010)
A kinetics analysis was conducted for the recovery of zinc (II) ions from a mine drainage sample by a liquid surfactant membrane containing di-(2-ethylhexyl)phosphoric acid as a carrier extractant and Span-80 as the ...
Kinetics and mechanism of the reaction of a nitroxide radical (tempol) with a phenolic antioxidant
(2003)
In the absence of redox-active transition metal ions, the removal of Tempol by Trolox occurs by a simple bimolecular reaction that, most probably, involves a hydrogen transfer from phenol to nitroxide. The specific rate ...
Folding kinetic pathway of phosphofructokinase-2 from Escherichia coli: A homodimeric enzyme with a complex domain organization
(2011)
Phosphofructokinase-2 is a 66 kD homodimer whose subunits are associated by means of a bimolecular domain, the β-clasp, which is linked to the larger portion of each subunit by a reentrant chain topology. To investigate ...
Nicosulfuron sorption kinetics and sorption/desorption on volcanic ash-derived soils: poposal of sorption and transport mechanisms
(Elsevier, 2020)
Nicosulfuron sorption/desorption kinetics were studied through batch sorption studies in ten volcanic ash-derived Andisol and Ultisol soils with acidic pH and variable surface charge. Two different kinetic models were used ...
Rapid kinetic studies of SH oxidation-induced calcium release from sarcoplasmic reticulum vesicles
(Academic Press Inc., 1997)
We studied the kinetics of calcium release induced by SH oxidation in triads isolated from frog and rabbit skeletal muscle by measuring calcium fluxes by a fast filtration method. In both species SH oxidation induced release ...
Oxidation of 3,5-ditert-butylcatechol catalyzed by copper(II) complexes. A kinetic study
(Elsevier Ltd, 1997)
Copper(II) complexes of the ligands (6-methyl-2,2′-dipyridyl)methane (MeDPM) and (6,6′-dimethyl-2,2′-dipyridyl)methane (diMeDPM) were prepared and used as catalysts for the oxidation of 3,5-ditert-butylcatechol to ...
Lipid Metabolizing Enzyme Activities Modulated by Phospholipid Substrate Lateral Distribution
(2011)
Biological membranes contain many domains enriched in phospholipid lipids and there is not yet clear explanation about how these domains can control the activity of phospholipid metabolizing enzymes. Here we used the surface ...
Degradation kinetics of chlorpyrifos and diazinon in volcanic and non-volcanic soils: influence of cyclodextrins
(Springer Verlag, 2018)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. The intensive use of insecticides such as chlorpyrifos (CPF) and diazinon (DZN) in the agricultural activities worldwide has produced contamination of soils ...
