A Fluid-Solid Coupling Mathematical Model of Methane Driven by Water in Porous Coal

open access: yesGeofluids, 2018
The existence of the water-driven-methane effect in gassy coal has been verified by field tests and laboratory experiments. However, a water-driven-methane mathematical model that considers methane adsorption and desorption has not yet been established ...

A Calculation Method of Thermal Pore Water Pressure Considering Overconsolidation Effect for Saturated Clay

open access: yesApplied Sciences, 2022
With the increase of soil consolidation degree, the pore water pressure induced by thermal loading drops dramatically. To conveniently and quickly calculate the thermal pore water pressure inside the soil under different overconsolidation states and ...

Model testing on rainfall-induced landslide of loose soil in Wenchuan earthquake region [PDF]

open access: yes, 2012
This study investigates the formation process of rainfall-induced landslide for slopes composed of loose soil in the Wenchuan earthquake region. Experimental investigations have been performed on the landslide's formation and the variation of the ...

Analysis of Non-Darcy Flow in Aquitard at Bottom of Foundation Pit Under Fluctuation of Confined Water

open access: yesShanghai Jiaotong Daxue xuebao, 2020
In order to better explain the phenomenon of foundation pit inrush caused by confined water, the Hansbo non-Darcy seepage theory was introduced into the Terzaghi one-dimensional saturated soil consolidation equation.

Influences of Pore-Water Pressure on Slope Stability considering Strength Nonlinearity

open access: yesAdvances in Civil Engineering, 2021
The pore-water pressure is a vital factor in determining the slope stability. To deal with the stability of slopes undergoing pore-water pressures, this paper used the pore-water pressure coefficient to develop the three-dimensional limit analysis method

Grain Configuration Effect on Pore Water Pressure in Debris Flow

open access: yesFrontiers in Earth Science, 2021
The generation and development of excess pore water pressure directly affects the grain interaction in debris flow, which can significantly reduce the friction strength and promote the movement of debris flow.

Dynamic Behavior of Bed Material around Bridge Pier under Abrupt Change of Water Pressure [PDF]

open access: yes, 1999
Major failure of structures usually occurs during flood flows due to scourin, sinking and sliding. These types of failure are considered to be in close relation to the dynamic behavior of bed material around the structures.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Transport of polymer particles in a oil-water flow in porous media: enhancing oil recovery [PDF]

open access: yes, 2018
We study a heuristic, core-scale model for the transport of polymer particles in a two phase (oil and water) porous medium. We are motivated by recent experimental observations which report increased oil recovery when polymers are injected after the ...
