Modified θ projection model-based constant-stress creep curve for alloy 690 steam generator tube material

Nuclear Engineering and Technology, 2022
Steam generator (SG) tubes in a nuclear power plant can undergo rapid changes in pressure and temperature during an accident; thus, an accurate model to predict short-term creep damage is essential.

General Procedure of Creep Test

, 2021
Regardless of the methodology adopted by each laboratory, there is a consensus about the three main stages in the creep testing procedure: the pre-cracking stage, the creep stage and the post-creep stage.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
