Mechanical Variability and Acoustic Emission Heterogeneity of Bedded Coal Under Uniaxial Compression

Bedding orientation affects coal strength and the interpretation of acoustic-emission (AE) signals, but detected activity and retrospective sequence descriptors have different monitoring meanings. Twelve coal specimens were tested under uniaxial compression, with three at each be...

Freezing performance of selective artificial ground freezing based on three-pipe structure and its influencing analysis

Selective artificial ground freezing (S-AGF) enables directional cooling and mitigates unnecessary thermal loss through air-insulated casings, thereby exhibiting superior energy-saving and stratum-protection performance relative to conventional artificial ground freezing (C-AGF)....

Spatiotemporal Variations and Environmental Correlates of Evapotranspiration Across Land-Use Types in the Longchuan River Basin

Long-term evapotranspiration (ET) information is important for water-resource assessment in basins associated with large-scale water-transfer projects. This study characterized ET variability and ET–environment associations across grassland, cropland, and forestland in the Longch...

Effects of N Reduction and Combined with Organic Fertilizer Application on Rice Yield and NH3 Volatilization from Saline Soil

Organic fertilizer (OF) application can significantly enhance soil fertility and crop yield. However, its influence on nitrogen (N) loss via ammonia (NH3) volatilization from reclaimed coastal paddy soil is not well known. We conducted a pot experiment here using cyanobacteria co...

Evolving frontiers in drinking water membrane technology: a 25-year bibliometric and antifouling perspective

Based on a comprehensive dataset of 5,925 publications retrieved from Scopus and the Web of Science Core Collection between 2000 and 2024, this study systematically maps the research landscape of membrane technology for drinking water production via integrated bibliometric analys...

Mo equivalent guided microstructural regulation and strength-toughness synergy of Fe-doped near β titanium alloy

The intrinsic strength-toughness trade-off, coupled with an inadequate understanding of microstructure regulation, restricts the further development of as-cast near β titanium (Ti) alloys with ultra-high strength and toughness. In this work, a series of Ti-7Mo-4Al-4Zr-3Nb-2Cr- x...

Runoff Simulation and Analysis in the Upper Yellow River Basin Using a Budyko–XGBoost Coupled Model

The Upper Yellow River (UYR) basin is the predominant runoff-yielding area of the entire watershed. Accurately simulating annual runoff is crucial for water resources management. While the Budyko framework effectively captures long-term hydro-thermal equilibrium, it struggles to...

Corn Straw Biochar–OPC Composites for Sustainable Treatment of Water-Rich Dredged Clay: Internal Curing Mechanisms, Pore-Structure Evolution, and Mechanical–Environmental Performance

High-water-content dredged clay is a water-rich sediment that requires sustainable, resource-oriented treatment, but conventional ordinary Portland cement (OPC) stabilization is hindered by excessive water-to-binder ratios, suppressed hydration, and high carbon emissions. This st...
