Similar simulation test study on the influence of mining on shaft deflection of deep soil based on hydraulic permeability model

Energy Exploration & Exploitation, 2023
Ensuring shaft safety is critical in the process of coal mining. During coal mining in the Guotun coal mine, Shandong Province, China, issues, such as shaft deflection, tank channel and shaft deformation, and tank jamming, which did not appear in the ...

Hydromagnetic Stability of a Slim Disk in a Stationary Geometry [PDF]

, 2002
The magnetorotational instability originates from the elastic coupling of fluid elements in orbit around a gravitational well. Since inertial accelerations play a fundamental dynamical role in the process, one may expect substantial modifications by ...

Analysis of load displacement in grape harvesters and corresponding effect on dynamic weighing system under laboratory conditions [PDF]

, 2011
Harvester bin dynamic weighing systems are affected by a number of sources of variation such as field slopes and load displacement. In grape harvesters, the nature of the material (wine grapes and wine grape juice) and its relative composition can vary ...

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+.

Dynamic responses of an underwater site subjected to plane P- or SV-wave incidence

Yantu gongcheng xuebao, 2018
The displacement responses of an underwater site due to plane P- or SV-wave incidence are studied. The site consists of a water layer and a saturated soil deposit overlying bedrock.

Kinematics of fault-related folding derived from a sandbox experiment [PDF]

, 2007
We analyze the kinematics of fault tip folding at the front of a fold-and-thrust wedge using a sandbox experiment. The analog model consists of sand layers intercalated with low-friction glass bead layers, deposited in a glass-sided experimental device ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
