Study on the influence of ground stress on liquid CO2 phase transition blasting damage and vibration effects

Meikuang Anquan
In order to reveal the influence of ground stress on the crack extension and vibration effect of CO2 phase change blasting, the crack extension characteristics and vibration effect of CO2 phase change blasting under different ground stress conditions ...

Spectral element method simulation of three-dimensional sedimentary basin under reverse-fault earthquakes

地震科学进展, 2020
Near-fault ground motion can cause serious earthquake disaster in the near-field area，especially when there is sedimentary topography in the area. At present，there are no reports on the ground motion response of sedimentary basins under the action of ...

Evaluation of underground blast-induced ground motions through near-surface low-velocity geological layers

Journal of Rock Mechanics and Geotechnical Engineering, 2023
Surface ground motion produced by underground blasts is significantly influenced by near-surface geological conditions. However, near-surface low-propagation velocity layers were always ignored in past analyses of ground motions due to their thin ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Peak Ground Velocities for Seismic Events at Yucca Mountain, Nevada [PDF]

, 2005
This report describes a scientific analysis to bound credible horizontal peak ground velocities (PGV) for the repository waste emplacement level at Yucca Mountain. Results are presented as a probability distribution for horizontal PGV to represent uncertainties in the analysis.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Effects of Near-Fault Ground Motions on Civil Infrastructure

Applied Sciences, 2023
Near-fault earthquakes (NFEs), characterized by high peak ground velocity (PGV) and long period pulses, show different properties from far-field ones [...]

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Monitoring the Dynamic Response of a Buried Polyethylene Pipe to a Blast Wave: An Experimental Study

Applied Sciences, 2019
Although the use of polyethylene (PE) pipelines has become increasingly widespread in recent years, few studies have addressed their seismic design and ability to withstand blast waves.
