Dynamic and static analysis of a kind of novel J energy-releasing bolts

Geomatics, Natural Hazards & Risk, 2020
Energy-absorbing rockbolt is now recognized as an important support element in deep mines around the world. A novel kind of energy-absorbing bolt called J-bolt was developed, which consists of anchoring (damping) module, deformation module, blending ...

Effects of external dynamic disturbances and structural plane on rock fracturing around deep underground cavern

International Journal of Coal Science & Technology, 2022
The occurrence of disasters in deep mining engineering has been confirmed to be closely related to the external dynamic disturbances and geological discontinuities. Thus, a combined finite-element method was employed to simulate the failure process of an

Oxygen impurities in NiAl: Relaxation effects [PDF]

, 2001
We have used a full-potential linear muffin-tin orbital method to calculate the effects of oxygen impurities on the electronic structure of NiAl. Using the supercell method with a 16-atom supercell we have investigated the cases where an oxygen atom is ...

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

FEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...
