Experimental Design of a High Vacuum System for PUPR-MC Plasma Machine
(Polytechnic University of Puerto Rico, 2008)
In vacuum technology it is customary to divide a large pressure region (as of today, covering 16 orders of magnitude) into single, smaller regions. These divisions are somewhat arbitrary. Thus, the chemists frequently refer ...

Hyperbolic, Ultrastatic Wormhole Solution to the Vacuum Effective Gravity Equations in Randall Sundrum Brane World
(Polytechnic University of Puerto Rico, 2005)
We provide a traversable wormhole solution to the effective vacuum gravity equations in Randall Sundrum brane world scenario. We argue that graviton effects from the bulk spacetime can stabilize the wormhole"s throat against ...
