Effect of Notch on Low Cycle Fatigue of AA 2024-T351
Abstract: Notch effect on low cycle fatigue of AA 2024-T351 was investigated. Decreasing notch curvature leads to less cyclic hardening. Values of fatigue strength exponent (b) and fatigue ductility (c) for notch specimens were out of range of metallic materials. The SEM examination showed multi-crack origins with secondary cracks and a large final-fracture zone for unnotched specimens, while there was small final fracture zone close to the center of the specimen …

Isolation, Production and Purification of Antibiotics Isolation from Microbes from Soil
Abstract: A chemical compound acting against life is called antibiotics. The term “antibiotic” literally means “against life”. The term appeared as early as 1928 in the French microbiological literature as antibiosis. The phenomenon of antagonism between living organisms was frequently observed even since 1877, when Pasteur and Joubert noticed that aerobic bacteria antagonized the growth of Bacillus anthracis. However, the world in its present restrictive meaning, “a chemical substance derived from …
