Mechanisms and control of mine floor heave. [PDF]
, 1996 Floor heave has been one of the important ground control problems in the underground coal mining industry. However, the mechanisms of floor heave have not been fully understood although some efforts have been made by many researchers.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Machine Learning for Thermodynamic States of Notional Nonideal Energetic Mixtures
Propellants, Explosives, Pyrotechnics, EarlyView.. ABSTRACT Currently, modeling the thermodynamic states in the reaction zone of a detonating energetic mixture entails iteratively solving a set of coupled differential equations that require detailed material property information or models whose empirical parameters must be physically measured.

Sustainable Development, EarlyView.ABSTRACT Although significant efforts have been made to prevent environmental degradation, the success of these initiatives has remained limited. The primary reason for this is environmental issues' complex and multidimensional nature. Economic, political, and social dynamics play a central role in shaping environmental problems, necessitating a ...

Far‐infrared sauna exposure at 65°C elevates core temperature
Experimental Physiology, EarlyView.Abstract Far‐infrared (FIR) saunas are increasingly used as a passive heating and ‘wellness’ modality, yet their capacity to elevate core temperature remains unclear, particularly given prior work at lower temperatures (∼45°C) reports limited net heat storage.
