Urbanization has greatly altered Earth’s surface form, and land use changes can lead to significant in carbon emissions. However, how these affect ecosystems remains unclear. Therefore, this study calculated the absorption emissions 31 Chinese provinces using high-resolution (300 m) data. Subsequently, a flow model was used evaluate transfer that occurred from every province between 2000 2020. The standard deviation ellipse analytic techniques were also employed research spatiotemporal...
This study develops a method to predict carbon dioxide (CO 2 ) emissions from the cement industry in Beijing-Tianjin-Hebei region using artificial intelligence-based neural networks. By analyzing data National Bureau of Statistics and China Statistical Yearbook (2010–2021), we calculated CO generated by fossil fuel combustion during production. The network model achieved robust predictive performance with root mean square error (RMSE) 0.05, absolute (MAE) 2,640,769 tons, coefficient...
The synergistic effect of Zn, N and moderate Fe doping enhances the ORR performance. maximum power density Zn/Fe-NC-0.5 MFC is 1954 ± 20 mW m −2 .
Abstract In order to improve the adsorptive properties of bentonite, a new poly(acrylic acid‐acrylic sodium) bentonite composite was prepared by copolymerization reaction. The composites were investigated. Based on amount acrylic monomers dissolution and Cd 2+ ions adsorption as objective functions, optimal conditions which determined with single‐factor experiments are follows: neutralization degree acid, polymerization temperature, time, mass ratio acid monomer unneutralized 20%, 80 °C, 3 h...
In this paper we introduce non-commutative analogues for the quasi-Hamiltonian $G$-spaces introduced by Alekseev, Malkin and Meinrenken. We outline connection with of quasi-Poisson algebras which author had earlier.

This study aims to explore various key factors influencing the academic performance of college students, including metacognitive awareness, learning motivation, participation in learning, environmental factors, time management, and mental health. By employing chi-square test identify features closely related performance, this paper discussed main utilized machine models (such as LOG, SVC, RFC, XGBoost) for prediction. Experimental results indicate that XGBoost model performs best terms...
Acid Rock Drainage (ARD) generated from oxidation of sulphide-bearing mine waste is one the main pollution problems associated with mining activities.Dry cover and water are normally used methods to prevent formation ARD.However, in Arctic region, harsh cold climate, vulnerability ecosystems drastic climate change make management different other non-Arctic regions.This paper reviewed several successful case studies dry applications industrial rest products further discussed possibilities...
