Life, 2014 Spring mounds on Earth and on Mars could represent optimal niches of life development. If life ever occurred on Mars, ancient spring deposits would be excellent localities to search for morphological or chemical remnants of an ancient biosphere.

CFD-DEM modeling of seepage erosion around shield tunnels
Tunnelling and Underground Space Technology, 2019 When tunnels are built in saturated silty sand, the tunnel leakage can carry fine particles into tunnels and generate seepage erosion process. During this process sand particles are subjected to high confining and hydraulic pressures and then are eroded ...

Deep Underground Science and Engineering, EarlyView.The graphical abstract illustrates the real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection. Under in‐situ hydrostatic pressure, the water invasion front advances progressively along the axial direction as the injection pressure increases stepwise, tracked in real time by nuclear magnetic ...

Mesoscopic seepage velocity characteristics during heap leaching based on magnetic resonance imaging
工程科学学报, 2015 Column leaching seepage processes were detected in a non-contact and non-destructive way by magnetic resonance imaging. Column leaching images were obtained when the flow was stationary and running.

A primary care‐led school‐centered model for epilepsy detection and care among children in India
Epilepsia Open, EarlyView.Abstract Objective We evaluated whether a primary care‐led, school‐centered epilepsy detection model, delivered through India's national school health program, Rashtriya Bal Swasthya Karyakram (RBSK), could improve childhood epilepsy detection and the knowledge, attitudes, and practices (KAP) of teachers and primary healthcare providers.

Energy Science &Engineering, EarlyView.One‐way FLAC3D‐COMSOL coupled modeling and field validation show that a 150 mm borehole radius with 5 m spacing provides the best coordination of plastic‐zone expansion, stress relief, permeability enhancement, and gas‐pressure attenuation, increasing the pure gas drainage rate by 35.4%. ABSTRACT To rationally determine the borehole radius and borehole

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.
