265Rg (Z = 111, t1/2 ≥ 108 y) in natural Au, an experiment was performed to enrich Rg in 99.999% Au. 16 mg of Au were heated in vacuum for two weeks at a temperature...

kinds of carbon stars are known to populate the region (Green et al. 1994). One kind is normal asymptotic giant branch (AGB) stars, carbon-enriched by dredge-up...

The enrichment of bone 13 C also implies that excreted material is depleted in 13 C relative to the diet. Since 13 C makes up about 1% of the carbon in...

cap, a leached zone, an oxidized zone, the water table, an enriched zone (supergene enriched zone) and the primary zone (hypogene zone). Pyrite FeS2 is...

of large numbers of nucleons (protons and neutrons) from the object hit. Carbon and oxygen nuclei collide with interstellar matter to form lithium, beryllium...

represent a Wolf-Rayet star exhibiting strong, broad emission lines of helium, carbon, and oxygen. Notation: let the symbol WN before the word star represent...

Draconis reveals it to be a metal-poor K-giant ([Fe/H]=-1.3) which is enriched in the heavy s-process elements. ... the other yellow symbiotic stars are...

higher thresholds for photoneutron production, as high as 18.72 MeV, for carbon-12. Def. "an energetic particle originating outside our solar system" is...

contrast with most other carbon and carbon-related stars (see reviews by McClure 1984a, 1985). The N, S, barium, CH, sgCH, and dwarf carbon stars all have significantly...

environmental emissions for the IC engine during its use phase. Ethanol-Enriched fuel (E85) is cheaper than gasoline, but has a lower mileage at 14 mpg...
