in this paper, effect of hydrogen diffusion on 2.25cr-1mo steel with ferritic-bainitic and martensitic microstructure has been investigated. hydrogen embrittlement of this steel was investigated by doing experimental such as delayed fracture and slow strain rate tests. result of this research was showed that the steel with martensitic microstructure strongly affected by hydrogen diffusion and ...

magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
Batch culture of Ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. The gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...
