Summary: Magneto-acousto-electrical tomography (MAET) is a powerful tool for various applications, such as medical imaging and process tomography. However, existing literature assumes a uniform static magnetic field, which is challenging to achieve in practice. This article presents a comprehensive mathematical model for MAET in the presence of nonuniform magnetic fields and demonstrates its effectiveness through validation in different test cases. The use of nonuniform magnetic fields leads to significant improvements in conductivity reconstruction, enabling the technique's application in bedside detection.

Summary: This study aimed to enhance the removal and mineralization efficiency of ciprofloxacin (CIP) using the integrated photocatalysis and fluidized bed biofilm reactor (FBBR) by introducing a magnetic field (MF) and B-doped Bi3O4Cl as the photocatalysts. The results showed that the addition of MF increased the degradation rate and total organic carbon (TOC) degradation rate, as well as accelerated microbial metabolism. The use of MF improved the performance of the integrated system and provided an efficient method for the treatment of wastewater containing antibiotics.

Summary: The effects of electrostatic field and static magnetic field on the quality of frozen broccoli and cauliflower were studied. It was found that the electrostatic field treatment at 3 kV/cm had the best overall effect, significantly reducing drip loss and improving the integrity of cells and the content of ascorbic acid. The magnetic field treatment was less effective compared to the electrostatic field treatment.

Summary: This study found that prolonged exposure to gradient high static magnetic fields can have negative effects on diabetic mice, including organ impairment, elevated blood glucose, inflammation, and anxiety. On the other hand, uniform high static magnetic fields did not produce the same effects. These findings provide important information for the future development and clinical application of high-field magnetic resonance imaging.

Summary: The innovative SM-ES method successfully preserved beef at -4 degrees Celsius for 14 days without ice nucleation, reducing drip loss by 21.9%, 47.8%, and 30.9% compared to refrigeration, slow-freezing, and freezing. The microstructure damage from crystallization was absent in SM-ES treated beef, and lipid oxidation decreased. SM-ES treatment extended the shelf-life of beef by over 6 days while preventing crystallization.

Summary: This study proves that fifteen three-dimensional classical minimally superintegrable systems in a static electromagnetic field have hidden symmetries that allow them to be linearized. As a result, the corresponding subsets of maximally superintegrable subcases are also linearizable. These findings further support the conjecture that all three-dimensional minimally superintegrable systems can be linearized through hidden symmetries, even in the presence of a magnetic field.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.

Summary: This study investigated the impact of magnetite on the nitrogen cycle of pig manure biostabilisation. The addition of magnetite increased N2O emissions and decreased NH3 emissions during composting. It also increased the total nitrogen content but should be considered for its significant increase in N2O emissions in engineering practice.

Summary: This study investigated the operation of a 1000L microalgae-based membrane photobioreactor system for continuous secondary wastewater treatment. The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
