It may act as a chelator capable of binding the minerals (calcium) of enamel or dentine, thus increasing the degree of undersaturation
and favouring demineralisation.
can build up to dangerous levels and deprive these animals of the basic building blocks they need to maintain their shells.
This "Report to an Academy" consists of reflections on how the restlessly cynical university has become the last self-appointed bastion of the humanities in an epoch of the undersaturation
of the age with history.
RS is the ratio of calcite activity product (Ka) to calcite solubility product (Ksp), SI value of less than 1 indicates undersaturation
, SI of 1 indicates saturation, and SI of more than 1 indicates supersaturation.
Simultaneously with the decrease in the influx of carbonate products by surface and subsurface waters as a result of considerable lixiviation of till layers, carbonate balance in lake water was disturbed: oversaturation was replaced by undersaturation
and the stage of Si[O.sub.2] prevalence in the ashy part of bottom deposits and formation of organic-mineral gyttja began.
In the Drain, the alunite disequilibrium coefficient indicated undersaturation
early in the 1997 wet season followed by supersaturation and then strong supersaturation with [D.sub.Alunite] >5 as the soil profile dried.
in the tropics during times of high river discharge, the oxidation of fine organic material in an estuary's floodwaters commonly leads to oxygen undersaturation
(Eyre and Balls 1999).
Mixing of groundwaters may lead to pronounced undersaturation
or supersaturation with respect to carbonate minerals, depending on temperature, pressure, and fluid composition, particularly pC[O.sub.2] of the mixed water.
Careful spotting of the blood sample on filter paper avoids inaccurate analysis results caused by undersaturation
, oversaturation, and abraded specimens.
Further, C[O.sub.2] supersaturation and [O.sub.2] undersaturation
were approximately of the same magnitude [ILLUSTRATION FOR FIGURE 4A OMITTED].
The undersaturated DO concentrations at the Oligohaline site indicate that respiration outweighs production (as was found by Durand and Nadeau, 1972), although it is possible that groundwater of low DO contributed to this undersaturation
Actual and anticipated petrographic effects of carbonate undersaturation
