Suppression of cellular and humoral immunity was confirmed by in vitro tests. After successful right adrenalectomy the clinical signs of Cushing's syndrom...

Petrologic Characteristics of the Lunar Surface

Petrologic analysis of the lunar surface is critical for determining lunar formation and evolution. Here, we report the first global petrologic map that includes the five most important lunar lithological units: the Ferroan Anorthositic (FAN) Unit, the Magnesian Suite (MS) Unit, the Alkali Suite (AS) Unit, the KREEP Basalt (KB) Unit and the Mare Basalt (MB) Unit. Based on the petrologic map and...

Metal in Ureilites: Petrologic Characterization

Introduction: Many of the petrologic characteristics of ureilites that are difficult to reconcile with normal igneous processes [1] can be explained by a smelting model, in which silicate mg (molar Mg/[Mg+Fe]) are controlled by carbon redox reactions [2-4]. However, their metal and siderophile element abundances appear to be inconsistent with such a model [5-7]. The smelting reaction (FeO + C →...
