Actual endotoxin levels in each batch are usually measured at < 0.13 EU/ml. Unlike manufacturers of other density gradient media, Axis-Shield do not have to offer special, more expensive, low endotoxin-containing products; all Axis-Shield Density Gradient Media have always been, and continue to be, produced to the same high rigorous standards. For every batch produced, a Certificate of Analysis...

All physically observable field parameters within the magnetosphere, such as particle densities and electric and magnetic fields, vary in both space and time. Understanding the underlying physical processes requires knowledge of both temporal and spatial variations of these parameters. Analysing data acquired simultaneously from two satellites allows determination of the component of the spatia...

Mechanisms determining the structure of edge temperature and density pedestals, which are associated with edge transport barrier (ETB) formation in tokamaks, are investigated on Alcator C-Mod. Experiments suggest a strong role for critical gradient behavior in setting profile characteristics of edge plasma. The maximum pressure gradient scales as the square of plasma current in both H-modes wit...
