Close relationship between the state of the oxygen evolving complex and rice cold stress tolerance
(Elsevier Ireland, 2020-03)
The results of the present work suggested arelationship between the growth stability and functional/structural parametersassociated to the primary photochemistry and oxygen evolving complex (OEC) intolerant rice plants ...
Dinuclear cobalt(III) and mixed valence trinuclear Mn-III-Mn-II-Mn-III complexes with a tripodal bridging pyridylaminophenol ligand
(Royal Society of Chemistry, 2016)
A dinuclear cobalt(II), [Co2(kappa(4)-O,O', N,N'-L)(2)(mu-O,O'-HCOO)](ClO4)center dot(C2H5)(2)O (1) and a linear mixed valence trinuclear manganese, [Mn-3(kappa(4)-O,O', N,N'-L)(2)(mu-CH3O)(2)(mu-O,O'-CH3COO)(2)]center dot ...
Voltammetric and spectroscopic study of the manganese-quinizarine-quinaldic acid mixed-ligand complex in dimethylsulfoxide
(PERGAMON-ELSEVIER SCIENCE LTD, 1997)
The combination of manganese(II) with quinizarine and the monoanion of quinaldic acid in dimethylsulfoxide yields a soluble deep-blue complex whose Mn-II:Qz(2-):ACQ(-) stoichiometry is 1:1:2. This complex is oxidized in ...
Manganese-quinizarin-pyrazinecarboxylic acid mixed-ligand complex in aprotic media. Formation of a manganese(III)-semiquinone binuclear species
(KLUWER ACADEMIC PUBL, 1999)
The monoanion of pyrazincarboxylic acid (PcA(-)), the dianion of quinizarine (Qz(=)) and manganese(II) yield a soluble deep-blue complex in dimethylsulphoxide whose Mn-II:Qz(=):PcA(-) stoichiometry has been established as ...
Oxygen consumption and the evolution of order: negentropy criteria applied to the evolution of ants
(1993-07-01)
Optimization of energy use by evolving organisms, predicted by theoretical extensions of the neo-Darwinian theory, i. contrasted with that of irreversible thermodynamics, which predicts an increase in orderliness and thus ...
Methodology for the recording and analysis of heart rate and oxygen saturation in adolescents, when they are playing video games
(American Institute of PhysicsPE, 2023-04-04)
Technology is changing people's daily lives because of the electrical devices that make people's day-to-day life easier. One of the most influential fields is the entertainment field, proof of this is the variety of video ...
Versatile activity of a copper(II) complex bearing a N4-tetradentate schiff baseligand with reduced oxygen species
(Wiley VCH Verlag, 2022-03)
The reactivity of the Cu(II) complex of N,N’-bis(pyridin-2-ylmethylene)propane-1,3-diamine (py2pn), [Cu(py2pn)(ClO4)2], toward O2.− and H2O2 has been examined. The complex reacts with O2.− with fast second order kinetics, ...
Geochemical evolution, residence times and recharge conditions of the multilayered Tubarão aquifer system (State of São Paulo–Brazil) as indicated by hydrochemical, stable isotope and 14C data
(2020-01-01)
The Tubarão aquifer system constitutes a very complex, multilayered aquifer enclosed in the Paraná basin (central-southern part of Brazil). Despite the relatively low productivity of wells, groundwater represents an important ...
