Mechanism of fault activation and water-conducting disasters induced by mining activities

open access: yesGeomatics, Natural Hazards & Risk
Stress disturbances induced by mining activities are among the primary factors promoting deep fault activation. In coal seam mining under the threat of high-pressure confined water, fault activation significantly increases the risk of water inrush.

Molecular Basis of Water Activity in Glycerol–Water Mixtures [PDF]

open access: yesFrontiers in Chemistry, 2019
Water activity (Aw) is a reliable indication of the microbial growth, enzymatic activity, preservation, and quality of foods. However, a molecular basis of Aw is still under debate in multiple related disciplines. Glycerol-water mixtures can provide a variation of Aws by controlling the ratio of glycerol and water. In this study, the molecular basis of
