Influence of construction-induced damage on the degradation of freeze–thawed lightweight cellular concrete

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3,   Pages 781-792 doi: 10.1007/s11709-021-0733-9

Abstract: During the construction of lightweight cellular concrete (LCC), material damage frequently occurs, causingThe construction-induced damage can be more significant than those from the service environment of LCCHowever, the effect of construction-induced damage on LCC during F–T cycles is often ignored and theIn this study, we investigated the factors causing damage during construction using a sample preparationThis study would serve as a guide for the construction and performance of LCC in cold regions.

Bacterial inactivation, DNA damage, and faster ATP degradation induced by ultraviolet disinfection

Chao Yang, Wenjun Sun, Xiuwei Ao

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 1, doi: 10.1007/s11783-019-1192-6

Abstract: • Long amplicon is more effective to test DNA damage induced by UV. • ATP in bacteria does not degradeWe used quantitative polymerase chain reaction (qPCR) to investigate DNA damage and evaluated adenosineThe results of qPCR effectively showed the DNA damage induced by UV when using longer gene amplicons,in that sufficiently long amplicons of both 16S and gadA indicated that the UV induced DNA damages.
