of structural iron on the surface charge and dissolution of dioctahedral smectites.
The observed changes in [F.sub.o] (initial fluorescence) and [F.sub.m] (peak fluorescence) are relative to the situation where the acceptor QA is reduced, since the rate of the competitor reoxidation
of QA by the pool of plastoquinone is lower than the rate of reduction of the (Zanandrea et al., 2006).
Gotoh and Yamashita  and Phillips  also observed the slow reoxidation
of Mn(II) formed in the reduced soil.
Therefore, it is presumed that the promoted reduction in air would be mainly because CO gas generated from reduction reacts with oxygen in air and releases heat, supplying the heat consumed by the direct reduction, and that the generated C[O.sub.2] gas can also impede the reoxidation
 found that lacking of PsbR cloud leads to decrease rates of oxygen evolution and quinone reoxidation
. Furthermore, mutation of PsbR in Arabidopsis leads to a decreased content of PsbP and PsbQ proteins , and plants with lacking PsbP awill be characterized with extensive defects of the thylakoid membrane , which is the main place for the transformation of light to the active chemical energy.
In addition, CHAPS and DTT affect protein solubilization because it prevents hydrophobic interaction and promote the reoxidation
of disulphide bonds avoiding the lack of proteins by aggregation or precipitation .
This causes the reduction of [Fe.sup.3+] and [Mn.sup.4+] into soluble [Fe.sup.2+] and [Mn.sup.2+], which is transported upward in the water column and oxygenated, resulting in the reoxidation
of insoluble metals to settle the soil and repeat the cycle .
The export process is coupled to reoxidation
of Fe(II) to Fe(III) by the ferroxidase enzyme ceruloplasmin and is followed by loading of Fe(III) onto transferrin for systemic distribution to other sites .
The samples were allowed to cool in an argon atmosphere to prevent reoxidation
, which took no more than 40 min.
Therefore, understanding reduction and reoxidation
kinetics is a fundamental starting point for deducing reliable structure-activity correlations.
We note that after deposition, copper shells undergo partial reoxidation
to [Cu.sup.2+] and [Cu.sup.1+], resulting in a mixture of copper oxidized forms.
The casting process also can introduce inclusions due to reoxidation
of the molten metal during pouring, as well as cause the entrainment of foreign debris that further adds discontinuities to castings.
