A sensitive and specific method based on liquid chromatography was developed and validated for the determination of phenytoin in human plasma using phenobarbital as internal standard. The drugs were extracted from plasma by liquid-liquid extraction and separated isocratically on a Phenomenex Synergi MAX-RP C12 column (150 x 4.6 mm i.d.), with water: acetonitrile: methanol (58.8:15.2:26, v/v/v) ...

This study was centered on improving the mechanical properties of AISI 8620 steel using carburization technique. The failure in service conditions many components such as cams, gears, and shafts necessitated research it demands that they possess both high wear-resistant surfaces tough shock-resistant cores. Standard test samples prepared from material were subjected to a pack process rice husk ...

Researchers have previously reported a negative association between romantic involvement and the discrepancy between the actual self and the ideal self. The authors present a schema-based model of romantic involvement and self-discrepancy to help explain this association, focusing on the impact of terminated relationships—“ghosts from the past.” In Study 1, participants primed with a past relat...

In the title compound, [Pb(NO(3))(2)(C(13)H(8)N(4))(2)], the Pb(II) atom (site symmetry 2) is hexa-coordinated by four N atoms from two N,N'-bidentate imidazo[4,5-f][1,10]phenanthroline (L) ligands and two O atoms from two weakly coordinated nitrate ions [Pb-O = 2.872 (5) Å] in an irregular arrangement, which may be ascribed to the stereochemically active lone pair of electrons on the metal ion...

Similarities in nuclear structure are observed for isotopes of odd-Z elements with even neutron numbers. These can be used to explain the α-spectra and to construct partial level schemes. Vice versa changes in the α-decay pattern may reveal a change of the ground-state (gs) configuration in the daughter nuclei. Results of previous studies were presented in the last year GSI Scientific Report [1...
