Abstract：This study aims to assess the impact of the new energy vehicle industry on urban air quality in China, focusing on the spatial and temporal variation of PM2.5 concentrations. Based on panel data from 286 prefecture-level cities in China from 2013 to 2022, an analytical framework is...

Climate change acceleration and intensifying global carbon reduction efforts have created an urgent need to understand how climate transition risks affect carbon emission efficiency in energy enterprises. Our study breaks new ground by developing climate risk indicators through machine learning and...

This study employs wavelet coherence, wavelet quantile correlation, and Granger causality tests to comprehensively investigate the dynamic correlation characteristics between the U.S.clean energies and the stock returns of seven systematically important banks (SIBs). The main findings are as follows...

Moving Bed Biofilm Reactor (MBBR) technology is applicable for removing organic components and nitrogen from wastewater in the Guheshwori Wastewater Treatment Plant (GWWTP). A lab-scale single-staged aerobic batch MBBR (16L pure volume, 5L active working volume) was designed and initiated using...

Hydrological monitoring in urban regions is crucial to analyze hydrology and manage floods. Nevertheless, monitoring flood overflow in urban areas including the degree of flood overflow is frequently insufficient. Hydrological models' ability to provide early flood warnings is limited by this...

This study aims to establish the effectiveness of nodule bacteria from Sesbania in eliminating nitrate (NO₃) and phosphate (PO₄) in wastewater from the sugarcane industry. The experiment was carried out for 60 days in which the wastewater was availed for treatment and Sesbania plants were modified...

The purpose of our study was to assess the adverse outcomes of exposure to toluene (Tol) on the male reproductive system and to investigate the potential efficacy of Punica granatum juice (PJ) and peel aqueous extract (PAE) against these effects. Rats were divided into the following groups: Control...

This study investigates surface water pollution in two dams in northeastern Algeria: Ourkiss Dam in Oum El Bouaghi Province and Babar Dam in Khenchela Province, over a year (March 2023 to February 2024). The research assesses pollution levels, organic contamination, and nutrient status using several...

Elucidating the mechanism of the correlation between urban spatial agglomeration processes and carbon emission levels can provide valuable scientific underpinnings for town planning under the constraints of low-carbon goals. This study investigates the characteristics of urban spatial agglomeration...

As global climate change intensifies, with frequent extreme weather events, the stability of vegetation is severely threatened. This study (2002–2023) uses NDVI, temperature, and precipitation data, along with methods like pixel binary, trend analysis, and multiple regression residual analysis, to...
