The vanadium isotopic constitution of petroleum asphaltenes: La Luna Formation (Venezuela) [PDF]
High resolution mass spectrometry indicates that the isotopic abundance of 50Vanadium (V) of the Late Cretaceous La Luna petroleum asphaltenes and related source kerogen of marine origin (both highly enriched with V > 2000 ppm) is higher by ...

Study on behaviors of PO43- in the sediment of the West Lake using isotope trace technique
Under laboratory condition, the technique of the isotope trace was applied to investigate 32P-PO43- behaviors in water/sediments of the West Lake. The results showed that 32P-PO43- in water/sediments declined exponentialy with time.

Nitrogen fixation sensitivity related to water use efficiency at reproductive development in soybean
Soybean [Glycine max (L.) Merr.] nitrogen fixation is sensitive differentially to drought among different genotypes at different growth and development stages, which directly affects soybean yield. Acetylene reduction activity (ARA) response to a gradual
