High Volume RF/Microwave SOI-CMOS Integrated Circuits

Building RF/microwave SOI-CMOS integrated circuits has significant speed and power advantages over circuits built on bulk materials. High quality SOI material exists today which will meet today's device requirements; on-going development efforts will improve the material available for subsequent device generations.     

Production of Ultra-High Charge States in Heavy-Ion Collisions

Charge-state fractions have been determined for iodine, selenium and bromine ions traversing oxygen, argon, krypton, xenon, carbon-foil and gold-foil targets. Particular attention has been paid to high charge states, some containing as little as 10-6% of the primary beam intensity. The measurements indicate that a TU tandem accelerator is capable of delivering useful beams of heavy elements up to bromine (including 82Se and 48Ca) with energies suitable for the research of super-heavy elements.     

Some thoughts on tolerance

In 4 duodenal ulcer patients the morphology of parietal cells has been studied before and one year after proximal gastric vagotomy (PGV). The average basal gastric acid secretion of the 4 patients was reduced from 9.2 m.mol/h before to 0.9 m.mol/h one year after PGV (90% reduction). The reduction in acid secretion was not accompanied by changes in the morphology of the parietal cells. Light microscopical studies indicated that the average cell size was about the same before and one year after PGV. Electron micro scopical studies showed only negligible changes in the parietal cell ultrastructure.
