Does zinc uptake relate well with differential zinc efficiency of barley genotypes?
To some extent, differential zinc (Zn) efficiency of cereals, particularly differences between species may be attributed to phytosiderophores (PSs) release and inorganic Zn (Zn2+) uptake; however, the discrepancies within a given species are still under discussion. Moreover, studies on the explanations of differential Zn efficiencies of barleys are limited. That is why using two barley (Hordeum vulgare L.) cultivars...

Quantification and correction of the Thomsen’s Delta Anisotropy for improved quantitative seismic interpretation in “AMFO” Field, Western Niger Delta
The Niger Delta is a sedimentary deposit with continuing sediment deposition to date. In a stratified earth, seismic waves tend to propagate faster along layers than across layer boundaries. Shales, due to the clay minerals they contain, exhibit similar behavior. As a result, velocities derived from surface seismic are often faster than well-derived velocities, causing depths of structures from surface seismic...
