Summary: This study investigates the impact of material design parameters on the physical and mechanical properties of recycled asphalt. A Box-Behnken design is utilized to determine the optimal preparation scheme for 17 groups of recycled asphalt. The effects of SMC regenerant content, SBS-modified asphalt content, and shear temperature on the mechanical properties of recycled asphalt are analyzed, and the optimal processing parameters are determined by a response surface model.

Summary: In this paper, a numerical model of the magnesium alloy hot-stamping process was established using the finite element solver ABAQUS/Explicit. The stamping speed, blank-holder force, and friction coefficient were optimized using the response surface methodology. The results showed that the maximum thinning rate of the sheet metal was most influenced by the blank-holder force, and the interaction between the stamping speed and the blank-holder force/friction coefficient had a great influence on the maximum thinning rate. The research provides a feasible optimization scheme for the analysis of the hot-stamping process of magnesium alloys.

Summary: This study found that plasma-activated water (PAW) is more effective in inactivating Escherichia coli and Staphylococcus aureus on blueberries compared to water treatment. The microbial inactivation of PAW is achieved by damaging the cell membrane and denaturing DNA. In addition, PAW treatment has a better effect on maintaining the freshness of blueberries.

Summary: This study evaluated the microbial treatment performance of a residential scale rain-to-hot-water treatment system in Melbourne, Australia, through long-term challenge tests. The UV system provided the majority of treatment, with the heat-pump hot water system deactivating any remaining microbes. Additional modeling work suggested that UV intensity, UV transmissivity, contact time, and temperature could be used as parameters to predict microbial treatment performance of the system.

Summary: Toxic cyanobacterial blooms are caused by the mass proliferation of photosynthetic prokaryotic microorganisms in water environments, posing serious threats to aquatic organisms and human health. A study in Lake Varese, northern Italy, found Cyanobacteria to be more abundant in the lake, with the blooms mainly dominated by the species Lyngbya robusta. Additionally, a specific functional profile characterized the bacterial population along the water column, and a large and diverse phage population was also identified in the shotgun data analysis.

Summary: This paper studied the influences of external factors on air-rib tents and found that the angle and number of wind ropes had a significant impact on displacement. The closer the wind ropes were to the center of the tarpaulin, the greater the displacement. Using response surface methodology, the optimal parameters were determined as follows: wind rope angle of 41 degrees, two wind ropes on the side, initial prestress of 800 Pa on the end face, and 0 Pa on the side. Under these optimal parameters, the maximum displacement decreased by 10.2%, while the maximum stress remained nearly unchanged.
