Nuclear reactor, any of a class of devices that can initiate and control a self-sustaining series of nuclear fissions.
Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952. Its most common isotope, einsteinium-253 (half-life 20.47 days), is produced artificially from decay of californium-253 in a few dedicated high-power nuclear reactors with a total yield on ...
North Korea Gaining Nuclear Bomb Skills; Nation Producing Its Own Key ComponentsSEOUL, South Korea * North Korean scientists are able to build crucial equipment for uranium-based nuclear bombs on their own, cutting the need for imports that had been one of the few ways outsiders could monitor ...
Mutagenesis studies with the monopartite begomovirus TYLCV have shown that the CP, V2 and C4 proteins mediate nuclear shuttling (CP) and cell-to-cell movement (V2, C4), respectively, the functions carried out by the DNA-B-encoded NSP and MP of bipartite viruses [30]. A major difference, ...
Incomplete understanding of the sources of secondary organic aerosol (SOA) leads to large uncertainty in both air quality management and in climate change assessment. Chemical reactions occurring in the atmospheric aqueous phase represent an important so
