ABSTRACT
The acceleration and extraction of uranium-238 nuclei by the Bevalac have been confirmed by their visual detection in nuclear research emulsion. A preliminary result for the collision mean free path for stopping uranium-238 (energy = 115 million electron volts per nucleon) is 3.1 +/- 0.6 centimeters. Qualitative characteristics of the observed uranium-nucleus collisions are also described.
ABSTRACT
A clinical example of perirenal compression producing documented renin-mediated hypertension is presented. The pathophysiology of this disorder is discussed as it relates to renin release mechanisms. In the future, recognition of the renal compression syndrome may obviate needless nephrectomies since simple removal of the source of compression should result in the cure of hypertension.

An experiment has been carried out at the bevatron on the nuclear fragmentation of nitrogen-14 ions at an energy of 2.1 billion electron volts (Gev) per nucleon. Because of the near equality of the velocities of the nitrogen-14 beam and the fragmentation products at an angle of 0 degrees , we find it possible to identify the nuclear fragments isotopically.
