PEPTIDES ELICITING T-CELL CYTOTOXICITY AGAINST HIV, PHARMACEUTICAL COMPOSITIONS CONTAINING THE SAME, AND KITS FOR DETECTING HIV INFECTION CONTAINING THE SAME

摘要

A piston-driven down hole pump and a method for using the same to lift fluid on both its upstroke and downstroke. The pump is powered by a waste water injection pump. A drive piston connected to a production piston and three-way valve power the down hole pump through the steady flow of the power fluid from the injection pump. The power fluid is exhausted into the well annulus and rises to the surface comingled with the fluid.
