Whole-rock Nd data provide information on the mean age of source areas contributing detritus to the sedimentary units in the mountain belt, regardless of their current metamorphic grade.
Total/NIOC (2003) in a joint study showed that, with the increasing age of source rock, the amount of C28 regular steranes in the samples decreases.
Adjusted for ethnicity, age of child, previous TB in the child, age of source case, alcohol use in source case and HIV status of source case, Test for trend, AOR adjusted odds ratio, CI confidence interval.
Adjusted for ethnicity, age of child, previous TB in the child, age of source case, alcohol use in source case and HIV status of source case, Test of trend, Regular alcohol use in source case as reported by the parent or legal guardian of the child, AOR adjusted odds ratio, CI confidence interval.
This paper presents a methodology, based on 3D electro-thermal simulation, to investigate failures of vertical power MOSFET due to metallization ageing of source terminal.
We advocate the need for further detailed field-scale studies on old DNAPL source zones that better resolve persistent pool/lens features and are of prolonged duration to assess the ageing of source zones.
In this age of multiple sources of unfiltered images the world witnessed both these unfolding developments in real time.
The age of the source case was associated with sputum smear status (p = 0.001), with older source cases less likely to have sputum smear-positive TB.
The spectrograms of a 90Sr+90Y β-source obtained with the specimen under study make it possible to evaluate the age of the source by the ratio of low- and high-energy regions of the spectrum.
