The Endangered Species Act and Private Property

Description: If the 103rd Congress embarks upon an effort to reauthorize the Endangered Species Act (ESA), it will run into an old acquaintance: the property rights issue. As now written, the ESA has at least the potential to curtail property rights (whatever its actual impact as implemented may be). This report explores the legal repercussions of those impacts, especially whether they constitute takings of property under the fifth amendment of the U.S. Constitution.

Geomorphology of plutonium in the Northern Rio Grande

Description: Nearly all of the plutonium in the natural environment of the Northern Rio Grande is associated with soils and sediment, and river processes account for most of the mobility of these materials. A composite regional budget for plutonium based on multi-decadal averages for sediment and plutonium movement shows that 90 percent of the plutonium moving into the system is from atmospheric fallout. The remaining 10 percent is from releases at Los Alamos. Annual variation in plutonium flux and storage … more

Neutron stars and nuclei in the modified relativistic Hartree approximation

Description: The properties of neutron-rich matter and finite nuclei are in the modified relativistic Hartree approximation for several values of the renormalization scale, [mu], around the standard choice of [mu] equal to the nucleon mass, M. Observed neutron star masses do not effectively constrain the valve of [mu]. However, for finite nuclei the value [mu]/M=0.79, suggested by nuclear matter data, provides a good account of the bulk properties with a sigma mass of about 600 MeV. This value of [mu]/M ren… more

Identification of nitriding mechanisms in high purity reaction bonded silicon nitride

Description: The rapid, low-temperature nitriding results from surface effects on the Si particles beginning with loss of chemisorbed H and sequential formation of thin amorphous Si nitride layers. Rapid complete conversion to Si[sub 3]N[sub 4] during the fast reaction can be inhibited when either too few or too many nuclei form on Si particels. Optimally, [approximately] 10 Si[sub 3]N[sub 4] nuclei form per Si particles under rapid, complete nitridation conditions. Nitridation during the slow reaction peri… more

Weld overlay coatings for erosion control

Description: A literature review was made. In spite of similarities between abrasive wear and solid particle erosion, weld overlay hardfacing alloys that exhibit high abrasion resistance may not necessarily have good erosion resistance. The performance of weld overlay hardfacing alloys in erosive environments has not been studied in detail. It is believed that primary-solidified hard phases such as carbides and intermetallic compounds have a strong influence on erosion resistance of weld overlay hardfacing … more
