Ages and stratigraphy of mare basalts in Oceanus Procellarum, Mare Nubium, Mare Cognitum, and Mare Insularum
[1] Accurate estimates of mare basalt ages are necessary to place constraints on the duration and the flux of lunar volcanism as well as on the petrogenesis of lunar mare basalts and their relationship to the thermal evolution of the Moon. We performed new crater size-frequency distribution measurements in order to investigate the stratigraphy of mare basalts in Oceanus Procellarum and related ...

Although petrographically distinct from all other Apollo 15 samples, it has been ignored since its first brief description.

متن کاملPregnant Mare Serum Gonadotropin
Procedures have been developed for the purification of pregnant mare serum gonadotropin (PMSG) and its a and jl subunits. The procedure for the hormone purification involves three steps of column chromatography on Sephadex G-100, DEAE-Sephadex A-50, and hydroxyapatite. The preparation of subunits involves the dissociation of PMSG with 10 M urea followed by their separation by chromatography on ...
