Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

Cobalt ion in a flowing solution was adsorbed onto the oxine-impregnated activated charcoal in a column. The initial rate of adsorption, K. Am, is influenced by either the flow rate or the ion concentration of a feed solution. The rate increases with a decrease in the concentration of the ion. However, with a solution of <0.06 μg.ml-1 of the ion, the adsorption rate tends to be constant at 0.90 ± 0.06 min-1. A relation between feed application time and column depth (bed depth/service time) has been determined that qualitatively agrees with that obtained from a theoretical calculation. Feed application time for different concentrations and flow rates of feed solutions can be predicted by the bed depth/ service time relation with a limited accuracy.
