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.

In the paper a new finite difference scheme assuring positivity of solutions in spectral codes based upon the Greuling-Goertzel approximation is developed. The method can be adopted in any code of this type without changing the execution time and storage requirements. The method has been applied in the Algol version of the BIGG code and found advantageous in the case of comparatively wide lethargy intervals when the standard central difference formulas could lead to instabilities.
