These relationships become even more complex when both precursor changes and changing climate are taken into consideration (Hogrefe et al. 2004).
The absorption properties of PDCs can be easily tailored by the design of the molecular precursor, changes in morphology, and volume fraction of the filler particles.
Screening for precursor changes in the mucosal linings preceding the development of invasive tumors and for accurate prediction of risk of malignant transformation, may be propitious opportunities, which are as yet difficult.
The addition of Sn to the precursor changes the morphology of the material causing partial formation of nanorods and leads to increase of average crystallite size from 33 nm up to ca. 40 nm.
However, the amplitudes of the subtle precursor changes are small and have low signal/noise ratios, meaning that accurately determining the parameters of the source of these changes is impossible, unlike the changes associated with the sub-Plinian eruptions and the magma effusion event.
We also show how the presence of nitrogen in the precursor changed the nanotube morphology, i.e. nitrogen decreased the number of kinks incorporated into the carbon nanotubes, decreased their length and diameter and increased the proportion of 'bamboo' shaped nanotubes.
Had we wished to do that, we would have needed to include realistic estimates of ozone precursor changes over the period of interest.
3. Whether there were precursor changes seen in UN/Sal/Chow offspring, which could potentially be markers for those at risk of developing metabolic syndrome and/or diabetes.
We do note, however, that as a result of the complex chemistry of ozone formation, ambient ozone concentrations do not necessarily change in direct proportion to precursor changes (Seinfeld and Pandis 1998).
Bold indicates genes where the expression change in the UN/Sal/Chow cohort (predisposed to metabolic syndrome) is also at least 1.25 fold, indicating that precursor changes are occurring in this group also.
