Summary: The removal of metal ions by the chelating membrane mainly depends on its adsorption capacity, while the retention of proteins is mainly influenced by their concentration in the solution. The chelating membrane performs poorly when the wastewater has high metal ion concentration and low protein concentration, but shows excellent separation performance when the concentrations are reversed.

Summary: In this study, bacteria from the genus of Azotobacter, Bacillus and Pseudomonas were isolated from Phaseolus vulgaris roots and used as plant growth-promoting bacteria for various plants. The results showed that different bacteria had different effects on plant growth in both sterile and non-sterile soil. Bacillus had the most influence on Sinapis alba in sterile soil, while Pseudomonas had the greatest effect on root and shoot length in non-sterile soil. Azotobacter stimulated the growth of Brassica napus in non-sterile soil, while Bacillus had a positive effect on Amaranthus retroflexus. Azotobacter also promoted the growth of Rumex patientia and Panicum miliaceum, while Pseudomonas enhanced the growth of Linum usitatissimum in non-sterile soil. However, not all differences observed in plants with the selected bacteria were statistically significant compared to the control.

Summary: The presence of high concentrations of metal ions in industrial metal coatings effluents has negative effects on the environment. To minimize their impact, it is important to reduce the concentration of metal ions before discharging the effluents. Sorption is an effective and low-cost method for reducing the concentration of metal ions. In this study, mustard waste biomass functionalized with an industrial polymeric thiocarbamate was used as a sorbent to remove Cu(II), Zn(II), and Co(II) ions from aqueous media. The results demonstrated the potential of this sorbent in treating wastewater contaminated with metal ions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
