Evolution laws and control technology of near and far stress field in hard roof mining roadway
Published 2024-12-01“…The maximum convergence of the roof and floor in the 15119 return airway, associated with the hydraulic fracturing of the new scheme, is 460 mm, and the maximum rib convergence is 430 mm, resulting in a 26.1% reduction in cross-sectional shrinkage rate. Consequently, the rock surrounding the gallery’s stress control scheme for both far-field and near-field has been proven effective, providing a theoretical basis and technical reference for similar galleries.…”

Removal of As(V) and Cr(VI) using quinoxaline chitosan schiff base: synthesis, characterization and adsorption mechanism
Published 2024-11-01“…The experimental data revealed that the adsorption kinetics follow the mechanism of the pseudo-second-order equation with R2 values (0.9969, 0.9061) in case of using CsQ and R2 values (0.9989, 0.9999) in case of using CsQG, demonstrating chemical sorption is the rate-limiting step of the adsorption mechanism. Comparing the adsorption efficiency of the synthesized Schiff base and the cross-linked one, it was found that CsQ is a better adsorbent than CsQG in both cases of As(V) and Cr(VI) removal. …”

Construction and application of copula-based trivariate standardized river disconnection index for seasonal rivers in arid and semi-arid areas
Published 2025-07-01“…Optimal distribution functions vary across regions, times, and datasets; therefore, using the best monthly distribution functions to compute SRI, SGDI, and SSMI provides a more scientifically robust mathematical and statistical basis. (2) The SSRDI, which combines surface water, groundwater, and soil water, is more consistent with the actual hydrological conditions of Tabu River compared to the three univariate indices. (3) From 2002 to 2020, the SSRDI for Tabu River shows a continuous declining trend, albeit at a slowing rate. The overall pattern exhibits a cyclical trend of worsening followed by improvement, with June being the month of most severe ecological river disconnection. (4) The seasonal component of the SSRDI from 2002 to 2020 displays cyclical changes, with a mutation in June 2004. …”
