Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

open access: yesDeep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Influence of Technological and Environmental Factors on the Major Ion Composition in Cooling Water Discharges of a Nuclear Power Plant

open access: yesEnergy Science &Engineering, EarlyView.
Statistical modelling and grey water footprint analysis revealed how technological and environmental factors shape the major ion composition of cooling water discharges from a nuclear power plant. Findings highlight that while ion concentrations increase post‐discharge, they remain within regulatory limits, ensuring minimal ecological impact.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
