Among them, solar dish concentrators are particularly notable for their ability to operate at high temperatures, making them an effective solution for both heat and electricity generation. Owing to their high efficiency in capturing and utilizing solar energy, dish collectors have attracted significant interest in solar thermal applications. These concentrators come in various cavity receiver designs—such as open, spiral, hollow, and volume configurations—allowing for versatile energy conversion. Building on this concept, the present study investigates natural convection heat transfer within a two-dimensional ‘C’-shaped cavity filled with a porous medium and hybrid nanofluids, specifically Ag-MgO (silver-magnesium oxide) and Ag-TiO<span>(_2)</span> (silver-titanium dioxide oxide). The cavity features adiabatic upper and lower surfaces, with a heated slit on the left and a cooled wall on the right. As solar devices become more compact and efficient, the shape of the cavity plays a critical role in ensuring proper thermal management to prevent overheating and sustain optimal performance. To enhance heat transfer in solar collectors, the study applies a machine learning technique, evaluating the influence of two distinct hybrid nanoparticles. Furthermore, machine learning is used to analyze how different parameters vary with the type of nanoparticle, aiming to determine the most effective combination for optimizing heat transfer. The governing equations are solved using the finite difference method coupled with the Marker and Cell (MAC) technique. The findings indicate that an increase in the Rayleigh number improves heat transfer owing to intensified buoyancy-driven convection, with Ag-MgO exhibiting greater efficacy compared to Ag-TiO<span>(_2)</span>.

This research used novel indigenous bacteria widely isolated from Tempe Lake in South Sulawesi, Indonesia, for cadmium reduction. Bacterial identification was performed using the 16S rDNA method. Measurement of Cd reduction was performed using atomic absorption spectrometry (AAS). Results revealed that, in Tempe Lake, heavy metal Cd values surpassed the minimum water quality level limits. Isolation of indigenous bacteria from the contaminated lake resulted in a total of six isolates, i.e., two isolates of rod-shaped Gram-positive bacteria and four isolates of cocci-shaped Gram-negative bacteria. These naturally occurring microorganisms were able to decrease Cd concentration in the bacterial medium by up to 68.93%. Based on their physiological profile, these native bacteria belonged to the genus <i>Bacillus</i>. According to the sequencing data that were analyzed using neighbor-joining phylogenetic analysis, the isolate was identified as <i>Bacillus albus</i> with 99% similarity. In conclusion, the native <i>B. albus</i> bacteria of Tempe Lake could be suggested as a potential bioremediation agent for heavy metals, specifically Cd, in contaminated water.

This study identifies the psychological factors influencing Iranian farmers' intention to conserve groundwater resources in the restricted Plain of Rumeshkan. This study was conducted using a cross-sectional survey method and was based on the Value-Belief-Norm theory, incorporating two additional constructs: feelings of pride and guilt. Multi-stage sampling was employed to gather the data. The sample size consisted of 282 farmers, and partial least squares structural equation modeling (PLS-SEM) was used for analysis. The reliability and validity of the questionnaire were assessed and confirmed. The findings indicated that the constructs of biospheric and altruistic values had a positive and significant effect on the new environmental paradigm. However, egoistic values did not significantly affect the new environmental paradigm. Additionally, the new environmental paradigm had a significant effect on awareness of consequences, and awareness of consequences significantly influenced the attribution of responsibility. Next, responsibility attribution positively and significantly influenced farmers' personal norms, and finally, personal norms positively and significantly affected farmers' intention to conserve groundwater resources. While the primary VBN model explained 30% of the variance in the intention to conserve groundwater resources, incorporating the constructs of guilt and pride increased its explanatory power to 40%, highlighting their fundamental role in motivating farmers' behavioral intention to conserve groundwater resources. This extension underscored the significance of emotional drivers in shaping groundwater conservation decisions. The developed VBN framework provides valuable theoretical and practical insights for policymakers, planners, and water management officials to promote groundwater conservation behaviors.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 9","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02578-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144918585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study uses pumping test data to re-evaluate and determine the extent of change in the Nubian Sandstone Aquifer System (NSAS) conditions with over-pumping operations, as it is considered the main aquifer in El-Kharga Oasis, Egypt. The study area experiences high drawdowns and a marked decrease in Piezometric Heads due to heavy exploitation. Twenty-one pumping and recovery tests were analyzed to obtain the Hydraulic parameters of the groundwater aquifer. In addition, the depths and levels of fourteen groundwater wells were measured to assess the water movement patterns and the distribution of the Hydraulic Heads in El-Kharga Oasis. The results show that the effective porosity of the NSAS varies from 21.7 to 28.3%, with an average of 24.7%. These values were used to estimate the Hydraulic Conductivity, which varies from 3.8 m/d to 16.1 m/d with an average of 8.07 m/d. Transmissivity values range from 75.6 to 1440 m²/d, and the Storativity range from 0.00000028 to 0.01125. The Transmissivity and Hydraulic Conductivity values in the study area show that sand is the main component of the groundwater layers. According to the Transmissivity values, the NSAS has moderate to high potential. The Hydraulic Head measurements vary from -22.5 m. in the center eastern part to 85.6 m. in the southwest.

Interactions between rainfall and runoff remain challenging due to data limitations and variability in hydrological conditions. This study integrates precipitation data and watershed characteristics in a hydrologic model to assess flood vulnerability of two watersheds (i.e., Maurice River and Raccoon Creek) in southern New Jersey. A sensitivity analysis revealed that land imperviousness exerts the strongest influence on peak runoff predicted by the model. The model was calibrated using past precipitation data and validated against observed peak runoff records. Model performance assessed using the fitting criteria of Normalized Root Mean Square Error and the Nash–Sutcliffe Efficiency demonstrated good agreement between calculated and observed peak runoff data. Model simulations based on 5-, 25-, 50-, 100- and 200-year return period precipitations were employed to predict the peak runoff from the watersheds. Precipitation projections using different scenarios including the high-emissions pathway (i.e., scenario where greenhouse gas emissions continue to increase throughout the twenty-first century, leading to significant climate-related changes) in global climate model were used to calculate the peak runoff. The results indicated a notable increase in peak runoff associated with high-emission precipitation projections from global climate model compared to return period-based peak runoff. These results highlight the redistribution of weather extremes, increased winter precipitation, and heightened flood risks in the watersheds.

The study found no discernible differences in the water compatibility standards for irrigation between magnetized water (MW) treated with an MF and non-magnetized water. However, using MW for irrigation greatly improved the productivity and efficiency of using fertilizer and water. When compared to irrigation with non-magnetized water (NMW), this resulted in a significant improvement in peach crop output. The results of the study showed that the amount of soil moisture in the root zone of crops increased significantly when MW irrigation was applied. More precisely within the first 200 m of irrigation from the (MF) device, the moisture content rose from 9.61% in the control treatment to 14.24%. When irrigation was extended from 200 to 400 and 600 m, the amount of moisture in the root zone drastically decreased. This illustrates that the effect of magnetizing irrigation water decreases with increasing distance between the irrigation region and the magnetic device at the field's beginning. Moreover, the results showed that the application of (MW) for irrigation resulted in improvements to the soil chemical properties. Consequently, this resulted in increased accessibility to water and improved uptake of fertilizers, ultimately leading to enhanced growth and production of peach trees as compared to irrigation with NMW.
