Modeling Major and Trace Element Chemistry of Zoned Metal Grains

Introduction: The compositional variations [1 and references therein] in the zoned metal grains from the CH and CB chondrites are generally interpreted as unequivocal evidence for their condensation from a parcel of H 2-rich gas with solar or somewhat increased dust/gas (D/G) ratios [2,3]. Although different origins of such gas are discussed [e.g., 4-7], its high enrichment in H 2 [8] and low a...

Time-sharing systems were the first to allow multiple users interactive access to their files in the same memory system. They were the first to allow users to specify who else could read and write their files. The password was invented as a means of identifying users to the system so that acces...

Introduction of SARS in France, March–April, 2003
