Effect of movability of water on the low-velocity pre-Darcy flow in clay soil

Journal of Rock Mechanics and Geotechnical Engineering
Water seepage in soil is a fundamental problem involving various scientific and engineering fields. According to the literature, low-velocity water seepage in low-permeability porous media, such as clay, does not follow Darcy's law, also known as pre ...

Perched groundwater simulation using the picard iteration‐based always active cell method

River, EarlyView.
Abstract Aquitards within the vadose zone impede vertical infiltration, leading to the formation of saturated perched groundwater. Perched groundwater flows laterally along aquitards, resulting in a heterogeneous spatial distribution of groundwater recharge that significantly influences groundwater formation and evolution.

Near‐Theoretical Redox‐Site Utilization and Fast Zn2+ Storage in a Polyimide‐CNT Cathode

Small, EarlyView.
A CNT‐integrated PTO‐based π‐conjugated polyimide cathode achieves near‐theoretical redox‐site utilization, ultrafast Zn2+ storage up to 20 A g−1, and exceptional cycling stability over 10 000 cycles in aqueous zinc‐ion batteries. ABSTRACT Achieving high utilization efficiency together with fast electrochemical transport remains a central challenge for

Numerical Modeling of CO2 and Brine Leakage through Open Fracture in a Fault Zone: Open Channel Flow or Darcy Flow

Geofluids, 2017
Understanding fluids migration and leakage risk along the fault zone is necessary to guarantee the safety of CO2 geological storage. The validity of Darcy’s law gets challenged in dealing with the flow in open fractures since the occurring of turbulence ...

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

High Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

ABAQUS Subroutine-Based Implementation of a Fractional Consolidation Model for Saturated Soft Soils

Fractal and Fractional
This paper presents a finite element implementation of a fractional rheological consolidation model in ABQUS, in which the fractional Merchant model governs the mechanical behavior of the soil skeleton, and the water flow is controlled by the fractional ...

Towards routine accurate electron‐density studies of biological macromolecules

Acta Crystallographica Section D, EarlyView.
Here, we describe the determination of the highest resolution structure in the PDB at 0.43 Å resolution. Electron‐density maps reveal extensive deformation electron density that is completely accounted for by performing transferable aspherical atom refinements using the DiSCaMB library in BUSTER.We report here the structure of Pyrococcus abyssi ...

‘Sinister Indian‐like Half‐circle’: Tennis, Orientalism and the White Racial Frame in the Twentieth‐Century British Sporting Press

History, EarlyView.
Abstract Examining sport alongside race, media and imperial power opens a rich field for understanding how macro‐level ideologies are shaped and circulated through everyday cultural forms. In twentieth‐century Britain, mass media framed and distributed narratives that rendered the empire's political realities intelligible to a broad public.
