The virgin olive oils (VOOs) under examination were from the main Tunisian cultivar 'Chemlali'. Olive fruits used for oil production were stored in plastic containers for four weeks at ambient temperature. Hydrophilic bioactive compounds and volatile profiles of the corresponding oils were analyzed.

Solvent extraction and supported liquid membrane transport studies for the preferential removal of Am(3+) from feeds containing a mixture of Am(3+) and Eu(3+) was carried out using 2,6-bis(5,6-dipropyl-1,2,4-triazin-3-yl)pyridine (n-Pr-BTP) as the extractant. Diluent plays an important role in these

N,N,N',N'-Tetraalkyldiglycolamides are extracting agents that are used for liquid-liquid extraction of trivalent metal ions in wet processing of spent nuclear fuel. This application places such agents in contact with the decaying radionuclides, causing radiolysis of the agent in the organic diluent.

The death of dopaminergic and other neurons in primary cultures of the mesencephalon could be induced by treatment with ceramide, as in lymphocytes where it mediates activation by the cytokines tumor necrosis factor-alpha and interleukin-1 beta of a novel sphingomyelin-dependent signaling pathway
Evaluation of mapping schemes for systematic coarse graining of higher alkanes.
