Temperature sensitive controller performance of MR dampers [PDF]
, 2009 Magnetorheological (MR) dampers can experience large temperature changes as a result of heating caused by energy dissipation, but control systems are often designed without consideration of this fact.

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 800-815, December 2025.The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.

Hydrodynamic Removal of Sediments in Open Irrigation Channel
Modern Agriculture, Volume 3, Issue 2, December 2025.The experimental study investigated the hydraulic behaviour of particle transport in an irrigation channel equipped with submerged longitudinal structures designed to reduce the effective cross‐sectional area. The findings demonstrate that the placement of parallel barriers along the flow axis generates localized acceleration and turbulence, which ...
