Air pollution has become a substantial environmental issue in China, which has seriously affected human health. To clarify the relationship among air pollutants, pollution sources, influencing factors, evaluation indicators and harms, it is essential to build a domain ontology for air pollution. Domain ontologies have been gradually accepted as a method to indicate the relationship between terms. However, there is not a complete ontology in air pollution domain, and building domain ontologies manually is time-consuming and inconvenient. In this paper, a semi-automatic approach is presented to build an ontology in air pollution domain. This paper proposes a method of entity relationship joint extraction based on attention mechanism, which is combined with core concept mining method to extract knowledge, and then concepts, relationships, and relevant instances are organized in hierarchy. Finally, the ontology model is constructed semi-automatically and semantic inference is also carried out. The research shows that this knowledge extraction method can avoid the error accumulation caused by entity recognition and relationship extraction and deepen the inner connection between them, and a large amount of effective knowledge in the field of air pollution can be extracted. In addition, the ontology constructed based on this method can also visually analyze the relationship between various classes and concepts in the field of air pollution, deduce the pollutant propagation path, and provide practical experience for the semi-automatic ontology construction in other fields and data support for further research. © 2020, Springer Nature Singapore Pte Ltd.

The traditional near-field acoustic holography technology (NAH) needs to adapt to the Nyquist sampling theorem, which requires numerous sampling points to be arranged on the holography plane to obtain accurate sound source reconstruction results. The Non-synchronous Measurements (NSM) was proposed to enhance the accuracy of reconstruction and reduce the measurement cost. However, the investigated object of conventional NSM are only sparsely distributed sound sources, and limited attention is paid to the reconstructed accuracy of the spatially extended sound source. In this article, the traditional NSM is further investigated in the spatially extended sound source, and the sound pressure information is reconstructed by Bayesian compressive sensing algorithm (BCS). Firstly, the spatially extended sound source is scanned by moving the rectangular microphone array, and the measurement effects of the microphone array with large aperture and high density are approximately obtained by using NSM technique. Then, BCS is applied to reconstruct sound field by the NSM of sound pressure. The results of numerical simulations demonstrate that the proposed study is applicable to the spatially extended sound source. NSM has advantages in reconstruction accuracy compared with the single measurement. At the same time, the reconstructed sound pressure under NSM can replace the simultaneous measurement(SM) results of multi-array without reference microphone, which avoids the limitation of using reference microphone in increasing the number of channels and spatial layout. The effectiveness and feasibility of the investigation are further proved by the experimental results of the driven steel plate. © 2023, The Authors. All rights reserved.

Modular multilevel converter(MMC) has a wide range of applications in the field of HVDC. However, some of the electricity in MMC is coupled, which makes the design of control system more difficult and have a negative impact on the stable operation of the system. This paper puts forward a strategy to eliminate the coupling control, this method compensates the current cross-coupling terms of the d-axis and the q-axis in the dq coordinate system, SOGI(Second Order Generalized Integrator) and Q-PR(Quasi-PR) controller are used to accurately control the double frequency circulation in the internal unbalanced current, the coupling caused by the internal unbalance current and the sub-capacitor module voltage is compensated in the three-phase coordinate system. Finally, the simulation verification is carried out in PSCAD, which is compared with the traditional control method to verify that the proposed method can achieve complete power decoupling.

Weathered crust elution-deposited rare earth ores (WREOs) are rich in medium and heavy rare earth. In order to improve the in-situ leaching process, which is prone to landslides and poor permeability, cationic hydroxyethyl cellulose (PQ-10) was used as a novel green swelling inhibitor and percolation promoter and was mixed with conventional leaching agent ammonium sulfate ((NH4)2SO4) to form a composite leaching agent to study the performance and mechanism of swelling inhibition and percolation promotion. Adding PQ-10 can inhibit the hydration swelling of WREOs, promote the percolation effect of the leaching agent, improve the rare earth (RE) leaching efficiency, and reduce the impurity aluminum (Al) leaching efficiency. Compared with the conventional leaching agent 2 wt% (NH4)2SO4, the percolation time is reduced by 50% by using the composite leaching agent (0.02 wt% PQ-10 + 2 wt% (NH4)2SO4). PQ-10 has positively charged quaternary ammonium groups and hydrophilic group hydroxyl groups, which makes it easy to adsorb on WREOs multiple sites through electrostatic interaction and hydrogen bonding, weakening the electrostatic repulsion between mineral particles, reducing the WREOs interlayer spacing, compressing the double electric layer thickness at the solid–liquid interface, weakening the mineral hydration swelling and increasing the percolation rate. The long carbon chains of the polymer entangle and link the fine mineral particles to agglomerate them, increasing their particle size and reducing their hydration dispersion, and preventing blockage of the percolation pores caused by migration of the fine particles through the ore body with the solution. PQ-10 molecules also insert the mineral interlayer and expulsion of the internal water, further inhibiting the swelling of WREOs. Adding PQ-10 reduces the surface tension of (NH4)2SO4 solution, improving the spreading and spreading ability of the solution, reducing the adhesion work between molecules in the solid–liqui

The coexistence of heavy metals and organic pollutants in aquatic ecosystems poses significant threats to environmental and human health. To address this issue, a novel carbon film-modified Bi5O7I photocatalyst (C/Bi5O7I) was developed for the simultaneous removal of bisphenol-A (BPA) and Cr(VI) under visible light. The C/Bi5O7I composite exploited the synergistic effect between the carbon film and Bi5O7I, enhancing light absorption and facilitating efficient electron transfer, which promoted the separation of electron-hole pairs. This mechanism enabled holes to degrade BPA and electrons to reduce Cr(VI), with each process mutually accelerating the other. The composite exhibited high photocatalytic activity across a wide pH range (3.0–11.0) and was minimally inhibited by typical water matrix components. Characterization techniques and theoretical calculations were employed to elucidate the degradation pathways, confirming the stability and efficiency of C/Bi5O7I over multiple cycles. This makes C/Bi5O7I a promising material for treating wastewater contaminated with coexisting heavy metals and organic pollutants.

Biochar can inhibit soil acidification by decreasing proton release from nitrification and improving soil pH buffering capacity (pHBC). However, as a kind of complex materials, the role of different components of biochar in inhibiting soil acidification induced by nitrification is still unknown. To fill this gap, dissolved fractions and solid particles of biochar were separated and mixed thoroughly with an acid Ultisol before an incubation study following urea addition. Results showed that both the dissolved fractions and solid particles of biochar inhibited soil pH drop caused by nitrification. The dissolved fractions of biochar inhibited soil acidification by decreasing the proton input derived from nitrification, while the solid particles of biochar did it by enhancing the soil pHBC. The dissolved fractions from peanut straw biochar (PBC) and rice straw biochar (RBC) decreased the proton release by 16% and 18% at the end of incubation. The decrease in proton input was attributed to inhibition of soil nitrification and mineralization caused by the toxicity of phenols in biochar dissolved fractions to soil bacteria. The abundance of AOB and total bacteria decreased by more than 60% in the treatments with biochar dissolved fractions. Opposite effects were observed in the treatments with biochar solid particles. Soil pHBC increased 7% and 19% after the application of solid particles of RBC and PBC, respectively. The plentiful carboxyl on the surface of biochar solid particles was mainly responsible for the increase in soil pHBC. Generally, the mixed application of dissolved fractions and solid particles of biochar induces a superior effect on inhibiting soil acidification. The negative impacts of dissolved biochar components on soil microorganisms should be closely supervised. © 2022, The Authors. All rights reserved.

Aflatoxin B1(AFB1) is a potent hepatotoxic and carcinogenic agent. Curcumin possesses potential anti-inflammatory, anti-oxidative and hepatoprotective effects. However, the role of LncRNAs in the protective mechanisms of curcumin against AFB1-induced liver damage is still *** is a newly discovered form of cell death in recent years. At present, the mechanism of curcumin on liver injury in chickens induced by AFB1 based on ce RNA regulatory network from the perspective of necroptosis and inflammation has not been reported. 1-day-old AA broilers were used as experimental animals. Based on the cases of established liver injury model induced by AFB1 exposure and curcumin intervention model both in vivo and vitro, as well as the model of LOC769044, miR-1679 and target STAT1 inhibition and overexpression LMH cell line in vitro. Transmission electron microscopy, RNA-seq, bioinformatics analysis tools, RT-PCR and western blot were performed. Dietary AFB1 caused hepatic morphological injury, and significantly increased the increased the expression levels of necroptosis related genes(RIPK1, RIPK3, MLKL), inflammatory pathways(TLR4, myd88, NF-κB) and cytokines(TNF-α, i NOS, IL-6, IL-1β). While, curcumin intervention significantly alleviated AFB1-induced broiler liver necroptosis and inflammation. Transcriptomic analysis showed that LOC769044 is the potential target Lnc RNA and located in the cytoplasm. ce RNA network prediction, dual luciferase reporter gene assay results showed that LOC769044 could bind to miR-1679, and miR-1679 could bind to STAT1. Inhibition and overexpression of LOC769044, miR-1679 and target STAT1 experiments indicated that LOC769044/miR-1679/STAT1 network plays an important role in regulating necroptosis in chicken hepatocytes, and curcumin can effectively alleviate AFB1-induced necroptosis in chicken hepatocytes by targeting LOC769044/miR-1679/STAT1 network. This study analyzed the possibility of LOC769044 as a new target for the prevent
