EPA bars AGS test

Chloroform: An EPA test case.

In March 1998, the U.S. Environmental Protection Agency (EPA) published a proposal to raise the drinking water maximum contaminant level goal (MCLG) for chloroform, a suspected human carcinogen, from zero to 300 parts per billion. The proposal marked a departure from the agency's traditional reliance on linear dose-response models in performing risk assessment, and reflected the new thinking co...

Counter-rotating bars within bars

The dynamical stability and evolution of disc galaxies with different disc thickness as well as various fraction and concentration of stellar counter-rotation is investigated with self-consistent numerical simulations. In particular, systems of nested, counter-rotating, stable bars are presented. As for the direct case, the nuclear secondary bar rotates faster than the primary bar. Contrary to ...

Graphs, Ags and Partitions

This paper deenes, for each graph G, a ag vector fG. The ag vectors of the graphs on n vertices span a space whose dimension is p(n), the number of partitions on n. The analogy with convex polytopes indicates that the linear inequalities satissed by fG may be both interesting and accessible. Such would provide inequalities both sharp and subtle on the combinatorial structure of G. These may be ...

First Beam Tests of the Muon Collider Target Test Beam Line at the Ags

In this report we will describe the muon collider target test beam line which operates off one branch of the AGS switchyard. The muon collider target test facility is designed to allow a prototype muon collider target system to be developed and studied. The beam requirements for the facility are ambitious but feasible. The system is designed to accept bunched beams of intensities up to 1.6x10 2...
