production phase, resulting in savings of tens of thousands of dollars per day and
increased process productivity by one-third. This resulted in lowering operating costs
and addition of previously uneconomic material to the process flow stream. I was able
to publish the results of this breakthrough in technology in many international
journals and was asked to speak at international forums on the subject. I was also
chosen as company liaison for public relations at numerous public gatherings. For
