Analysis on the evolution law of creep-fatigue failure energy of deep anchored jointed rock mass
Zhongguo dizhi zaihai yu fangzhi xuebao, 2022 In order to explore the mechanical properties of deep rock masses under disturbance loads such as blasting and excavation, laboratory tests of anchored rock masses under creep-fatigue loads were carried out, and the law of energy evolution was further ...

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

An experimental study on strength behaviour of Jointed Rock Mass through modelling under uniaxial compression tests [PDF]
, 2008 Stability analysis of a rock mass is an important and complicated problem related to the safety of engineering buildings. One of the major tasks of engineering geomechanics is to evaluate the rock mass stability both qualitatively and quantitatively. The

Preparation of Jointed Rock Mass Model Using Intact Rock Specimen and Its Characteristics of Resistivity [PDF]
, 2003 Before the underground structures such as tunnels will be constructed, because of the sensitivity for the water included for the rock mass, electrical prospecting for geological surveys is often executed. However, the relationship between resistivity and
