In this study, the qualitative research method is based on the documentary analysis. The statistical population consists of existing documents selected via purposeful sampling method. The sample size has been more than 250...

My Century of Physics

I became an undergraduate at Dartmouth College in 1933. The freshman course in physics was given by G.F. Hull who with E.L. Nichols, the founder of the Physical Review, was the first, with P. Lebedev in Russia to measure the pressure of light. (The world would learn sometime later about the diabolical importance of the pressure of light in enabling the hydrogen bomb.) Hull was a Canadian who ha...

MICROBIAL TRANSFORMATION OF CHOLESTEROL BY MYCOBACTERIUM SMEGMATIS

Mycobacterium smegmatis PTCC 1307 (CIP 73.26) was used as a microbial agent to produce androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione, two useful precursors in the synthesis of steroid drugs. The side chain of cholesterol, as the substrate, was selectively cleaved in the presence of five enzyme inhibitors. An intermediate structure with intact side chain, cholest-4-ene-3-one, ...
