Columbium (niobium) recycling in the United States in 1998
Larry D. Cunningham
2001, Open-File Report 2001-348
This report describes the flow of columbium in the United States in 1998 with emphasis on the extent to which columbium (niobium) was recycled/reused. Columbium was mostly recycled from products of columbium-bearing steels and superalloys; little was recovered from products specifically for their columbium content. In 1998, about 1,800 metric...

Atlantic salmon (Salmo salar) were extirpated in much of New York state by the late 1800s. Currently, Atlantic salmon from Little Clear Pond (Saranac Lake, NY) are stocked in Cayuga Lake (Ithaca, NY) and Lake Ontario to support a fishery, but reproduction is severely impaired by thiamine deficiency in Cayuga...
Energy-to-moment ratios for damaging intraslab earthquakes: preliminary results on a few case studies
Emile A. Okal, S. H. Kirby
2001, Open-File Report 2002-328
We use the energy-to-moment ratio, as introduced by Newman and Okal [1998] to examine the source characteristics of normal-faulting intraslab earthquakes, compared to nearby interplate thrust events, based on recent case studies in central Chile and southeastern Mexico. In Chile, we find that the 1997 intraslab event had an exceptionally...
