A Study of the influence of rock mass structure on the propagation processes and deposit characteristics of rockslides

The failure of high-positioned rock slope often occurs in alpine and gorge regions of southwest China, resulting in huge casualties and economic and property losses.At present, there are many research theories and physical models for rock landslides, but these theories and models ignore the structural characteristics of rock mass.However, for rocks

Maize Thymidine Kinase Activity Is Present throughout Plant Development and Its Heterologous Expression Confers Tolerance to an Organellar DNA-Damaging Agent

Thymidine kinase 1 (TK1) phosphorylates thymidine nucleosides to generate thymidine monophosphate.This reaction belongs to the pyrimidine salvage route that is phylogenetically conserved.In the model plant Arabidopsis thaliana, TK activity contributes to maintain nuclear and organellar genome integrity by providing deoxythymidine-triphosphate (dTTP
