Effective removal of fluoride corresponds with decrease in intensity of transmittance which indicates exchange of OH− from the surface of the adsorbent for F− ion during adsorption.
In the villages, most respondents indicated exchange of sex for both money and a gift (57.5%).
Chloro-alkaline indices reveal that the majority of samples show negative values in all the litho units indicating the exchange of Na and K in groundwater with Mg or Ca in rock.
Individual replacement of positively charged residues in the MPDM helices with glutamine (Gln) did not abolish the cation uptake activity of plant HKTs, indicating that exchange of one of the positively charged residues in the MPDM helix of plant HKTs with a hydrophilic residue can be tolerated [ 66].
In direct exchange, the indices are positive which indicates ion exchange of Na+ and K+ from water occurs with Mg and Ca in the rock.
To know the direction of exchange during the path of groundwater through the aquifer, Schoeller (1967, 1977) suggested two chloro-alkaline indices CaI1 and CaI2 to indicate the exchange of ions between groundwater and its host environment.
Careful analyses revealed many fusion events amongst individual inclusions either separated by short or long distances, and also fission events (Fig. 2d, e, Supplementary Fig. 1, Supplementary Movies 2 and 3), which indicates constant exchange of material and deformability.
Carbon isotope-labeling experiment indicates rapid exchange of the surface-adsorbed and gas-supplied carbon atoms at the higher temperature, resulting in the highly crystallized graphene with energetically most stable orientation consistent with the underlying Cu(1 1 1) lattice.
These findings indicate that exchange of pyruvate with TCA cycle intermediates, rather than oxidation of pyruvate via acetyl-CoA, correlates with glucose-stimulated insulin secretion.
They indicate the exchange of Na and K from the water with Mg and Ca of the rocks which are mainly of granitic origin (Nagaraju et al. 2015).
