Sphagnum ones ("Rigida" and "Squarrosa") has been clarified using molecular phylogenetics. All but two species normally identified as "Sphagnum" reside in one clade; two other species have recently been separated into new families within the Sphagnales reflecting an ancestral relationship with the Tasmanian endemic "Ambuchanania" and long phylogenetic distance to the rest of "Sphagnum". Within main clade of "Sphagnum", phylogenetic distance is relatively short, and molecular dating methods suggest nearly all current "Sphagnum" species are descended from a radiation that occurred just 14 million years ago. "Sphagnum" mosses occur mainly in the Northern Hemisphere in peat bogs, conifer forests, and moist
Resende Nuclear Fuel Factory Resende Nuclear Fuel Factory The Nuclear Fuel Factory (FCN) is located near Resende, state of Rio de Janeiro, comprising three units, and has a production capacity of 280 tons of uranium per year. At present, FCN was modernized and produces at the Components and Assembly Unit the fuel rods and fuel elements needed for Brazilian nuclear reactors. The Reconversion and Pellets Production Unit is operating since 1999 with a capacity of 160 tons of UO2 pellets/year. The UO2 reconversion line uses the AUC process. The Nuclear Fuel Factory also produces other fuel element components, such as top and bottom nozzles,
