'extent of ageing' is a correct and usable phrase in written English.
It can be used to refer to the physical or mental signs of ageing. For example: "Her wrinkles indicated the extent of ageing she had gone through in recent years."
Furthermore, our results suggests that, by coupling NIR spectroscopic investigation with chemometric exploratory data analysis can be a suitable approach for determining the presence of contaminants and for assessing the extent of ageing in the paper samples to be handled.
As such, the extent of ageing, the health needs of the ageing population, as well as the implications of national policies for the health and welfare of the aged are poorly understood and yet to be well appreciated.
De-aging, by heating aged specimens to higher temperatures but below Tg, was observed to reduce the extent of physical aging and the increase in the rates of crystallization closely followed the residual extent of aging.
Differential scanning calorimetry indicated that the MWCNTs acted as nucleation points, increasing the crystallization temperatures of PP-MWCNT, which reduced the extent of aging.
Defects/soft lattice inclusion due to different methods of material synthesis, extent of aging, reaction medium and associated solvent molecules have enormous influence on the particle size and magnetic properties of these complexes.
The lack of reactivity of the Riverside PM samples has been explained by a higher extent of aging in the atmosphere prior to sample collection.
Together, this means that any observed extent of aging should be due to the presumably small fraction of non-repaired, toxic damage.
The control variable for aging (the proportion of elderly persons) was significantly negatively associated with bed density (at the 1% level), suggesting that bed supply had not caught up with the extent of aging.
There is more empirical backing for the predictions of UnicellAge than the existence of active repair machinery in all organisms studied and the limited extent of aging in some bacteria and fission yeast under benign conditions.
Further applications are set out to assess the extent of age misreporting in the four censuses.
However, the nature and extent of age-related HPA axis deficits vary considerably across and indeed, within strains.
