An Investigation on Hydrogen Embrittlement of the Cr-Si Spring Steel Using Slow Strain Rate Test and Weibull Model [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2015 In this paper, the hydrogen embrittlement of the high strength Cr-Si spring steel with after Zn-12%Ni electroplating, have been evaluated. Slow strain rate test with 3.34 × 10-6 sec-1 strain rate was performed, and the hydrogen embrittlement index of the

Reducing ppGpp level rescues an extreme growth defect caused by mutant EF-Tu.
PLoS ONE, 2014 Transcription and translation of mRNA's are coordinated processes in bacteria. We have previously shown that a mutant form of EF-Tu (Gln125Arg) in Salmonella Typhimurium with a reduced affinity for aa-tRNA, causes ribosome pausing, resulting in an ...
