Due to their excellent oxidation resistance and creep resistance at elevated temperature, alumina-forming austenitic (AFA) stainless steels have emerged as potential alloys for high-temperature applications. In this study, a reactive air aluminizing

The effect of reactive air aluminizing (RAA) on the high temperature oxidation behavior of the H230 superalloy is studied at 850 °C for 600 h. Mass gain values are measured and microstructure is studied by XRD, SEM, and EDX. Post oxidation mass gain

This paper deals with methods of producing high and consistent yields of Type A and Type B Clostridium parabotulinum toxins. It is shown that highly toxigenic strains readily lose toxin producing activity and that this type of variation may be largel

“When I see you setting off down the road on Monday morning,” the village schoolmaster once said to me, “I sometimes wonder if you are regarding human life as radically as you did when you were preaching in the kirk the day before. You seem, so
