Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.ABSTRACT In Namibia, the aquaculture sector faces significant challenges, mainly due to the high cost of imported commercial feed, which limits small‐scale farmers' productivity and food security. To address this, locally formulated feeds must be evaluated as sustainable alternatives.

Energy Science &Engineering, Volume 14, Issue 8, Page 3625-3637, August 2026.This study primarily investigates the optimal width for coal pillar retention in both sides of the worked‐out face section. Taking the 42201 haulage roadway of the 42201 working face at Shengxin Coal Mine as the primary research target, it analyses the optimum width for coal pillar retention through theoretical calculations, numerical simulations, and ...

Modeling of Floor Heave in Underground Roadways in Dry and Waterlogged Conditions
, 2022 Floor heaving is a phenomenon that occurs in almost all mining roadways and tunnels. It can restrain the advance of the heading face or cause serious problems during roadway use. The highest levels of floor uplifting are observed in coal mines, which can

The mechanism of roadway deformation in conditions of laminated rocks
Journal of Sustainable Mining, 2018 The high stress condition of the rock mass requires a change in the approach to the design and usage of roadway support. It is necessary to take into account the mutual deformations of the ''support – rock mass'' system, as well as the peculiarities of ...

Frost heave in compressible soils [PDF]
, 2010 We develop a mathematical model of frost heave in compressible soils based on a morphological instability of the ice–soil interface. The theory accounts for heave and soil consolidation,while avoiding the frozen fringe assumption.
