This refraction enhances the surface scattering and affects the accuracy of sound field simulation, and underwater sound source localization. This research investigates the impact of sound speed profile mismatch due to wind-generated bubbles on the matched field sound source localization in a shallow-water environment of the Persian Gulf. A bubble layer and a sound propagation Parabolic Equation models are combined with a high-resolution maximum-likelihood matched field processor to calculate and analyze the acoustic pressure field and source localization in the bubbly environment. To calculate the localization error, the bubble environment is compared to the bubble-free environment in five wind speeds from 6.6 to 10.2 m/s, source depths of 10, 45, and 75 m, and nine acoustic frequencies ranging from 2 to 10 kHz. The results demonstrate that the range and depth localization errors increase by increasing the degree of the mismatch and the source frequency. However, the errors are significant only at frequencies equal to or higher than 8 kHz and wind speeds greater than 8 m/s. Moreover, the values of these errors depend on the source depth. This result indicates that the errors of the source located at a depth of 10 m are more than those in the source in depths of 45 and 75 m. The matched field processor overestimates the source range and depth. The range estimation error is less than that of depth.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"21 14","pages":"9139 - 9156"},"PeriodicalIF":3.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141112947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Likewise, regarding environmental considerations, the values of environmental emissions and their external costs in different power generation methods were modeled for the first time in an inclusive electricity system. Then, the Matrix Laboratory and Long-Range Energy Alternative Planning software were used to model electricity supply and demand toward long-time planning and estimate and solve technical, economic, and environmental functions. The modeling outcomes showed that, under the Steam Power Plant repowering scenario, the efficiency-improving actions in thermal power plants were prioritized over the development of clean and renewable power plants, including large hydroelectric and nuclear power plants, and could reduce the total power generation cost by 38% until 2050 and environmental and greenhouse gases emissions by 3,572 MMT and 2,624 MMTDCO2E compared to the BAU scenario. It was also found that although developing renewable energies could decrease the external environmental costs by 73,188 million U.S dollars in the 2017–2050 period relative to the other scenarios, its development would not be optimal technically and economically since it was a function of technical, economic, environmental, and political factors and was not the sole approach to reducing carbon emissions in all countries.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"21 14","pages":"9007 - 9030"},"PeriodicalIF":3.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141120138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, the synthesis and optimization of MIPs@H₂S-specific nanoadsorbent of hydrogen sulfide gas were done using the response surface method. Initially, the synthesis of MIPsNIPs@H₂S nanoadsorbent was done by the SIP method and four variables, including dose, temperature, concentration, and flow, which were decided upon utilizing RSM with central compound design. Thirty experiments were also designed to optimize the variables affecting the adsorption capacity. Besides, physical characteristics were determined by FTIR, XRD, FE-SEM, BET, and total pore volume and nitrogen adsorption. The analysis of variance indicated a linear model, while the adsorbent dosage and temperature are the most important process variables to calculate the optimal operating conditions of the process affecting the H₂S adsorption capacity. The projected results of the linear correlation demonstrated excellent concurrence with the experimental observations. The optimal process variables obtained from numerical optimization were equal to the adsorbent dose of 1.32 gr, concentration of 752.2 PPM, flow of 85 ml/min, and temperature being equal to 42.5 °C.

However, they have adverse environmental impacts due to discharging pollution to the surface waters. To quantify the sustainability of this industry with the perspective of environment-food nexus, the-state-of-the-art index of food environmental footprint (FEF) is used and calculated for trout ponds (TPs). For this purpose, an integrated method is developed for accounting the environmental impacts of TPs by including grey water footprint (GWF) in Recipe, a tool for life cycle impact assessment (LCIA). GWF stands for the embedded water consumption and LCIA combines the potential health and ecological impacts. Here, water quality data of multiple pollutants, BOD, COD, TSS, NO₂, NO₃, NH₄, TN, PO₄, DO and Cu⁺², in the influent and effluent of Iranian TPs was obtained by field experiments and discussed with data from 9 countries. Results showed that TSS and NH₄ are critical pollutants and the average GWF is about 16 m³/kg. Moreover, human health impacts are relatively greater than ecological damages. Nevertheless, FEF is calculated 0.17 and verifies TP sustainability (&lt; 1). Based on environment-food nexus perspective; it means that the positive value of food production dominates TPs’ negative environmental damages. In addition, this study reviewed the efficiency of constructed wetlands for low-strength wastewater treatment.

Computational models were implemented using MATLAB, integrating Radial Basis Functions (RBF) as the interpolation technique. The process commenced by establishing a groundwater flow model, where hydraulic head served as the foundational parameter for determining seepage velocity under unsteady-state conditions.
