There were no studies of drug use and the development of control policy in either Britain or the USA. Issues such...

A stable water isotopologue-enabled cloud-resolving model was used to in-2 vestigate the cause of the amount effect. Results indicate that, as convec-3 tion becomes stronger, the δD of precipitation (δD p) depends on the isotopic 4 composition of the converged vapor more than that of surface evaporation.

The green synthesis approach has benefits over traditional methods in silver nanoparticle that involve chemical agents interrelated environmental toxicity. For this reason, been preferred for the biosynthesis of nanoparticles (AgNPs). In addition, produced through plants are much more stable, large size and shape range can be biosynthesized high amounts. Silver were synthesized from compound (A...

Hyoscyamine, anisodamine and scopolamine are tropane alkaloids present in some Solanaceae species used modern medicine. L-Hyoscyamine is hydroxylated to 6β-hydroxyhyoscyamine (anisodamine) then epoxidated by the dual action of hyoscyamine 6β-hydroxylase (H6H), a 2-oxoglutarate dependent dioxygenase. A natural mutation Gly-220 residue Cys was previously shown be associated with loss function H6H...

The theme of suicide appears several times in ancient Greek literature. However, each such reference acquires special significance depending on the field from which it originates.
