C/N ratios can be used to distinguish the source of OM [50]: higher C/N ratios (13.7 ± 4.3) in the marsh sediments indicates a mixture of vascular plant and marine algal sources, whereas the lower C/N ratios in shelf sediments (9.6 ± 0.9) indicates that organic matter was derived more from phytoplankton.
Strontium isotope ratios in the outer shelf core date its oldest coral remains to between 490,000 and 1.05 million years old.
Moreover, the improved ratio of RAO treatment was better than shelf procedure (P = 0.015) and Chiari osteotomy (P = 0.0007), and the descendent range of shelf procedure was greater than Chiari osteotomy (P = 0.018).
Moreover, the improved ratio of RAO treatment was better than shelf procedure significantly (P = 0.015) and Chiari osteotomy (P = 0.0007), and the descendent range of shelf procedure was greater than Chiari osteotomy significantly (P = 0.018).
The shelf edge is associated with the largest displacement, expansion ratios and thickness of prograding deltaic sequences.
Based on diagnostic ratios of PAH isomers and principal component analysis, shelf sediment PAHs were petrogenic and those from marsh sediments were pyrogenic.
The inventory-to-sales ratio, which measures the time that goods remain on shelves, rose to 1.38 months in February from 1.36 months in January.
A separate report showed business inventories fell for an eighth consecutive month in September, but sales plunged 2.8percentt, pushing up the inventory-to-sales ratio, a measure of the time goods sit on shelves.
The inventory-to-sales ratio, a gauge of how long stockpiles stay on shelves at the current sales pace, was 1.37 months in March, figures from the Commerce Department showed today.
The inventory-to-sales ratio, which measures how long it would take to clear shelves at the current sales pace, edged up to 1.16 months' worth.
The inventory-to-sales ratio, which measures how long it would take to clear shelves at the current sales pace, was unchanged at 1.26 months' worth.
