aims: in biological wastewater treatment processes, a large amount of sludge is produced. stabilization of sludge is essential before disposal because of the risks to human health and environment. therefore, selecting an appropriate process for stabilization this sludge may efficiently decrease risks. the aim of this study was to examine the compound efficiency of the advanced fenton and ozonat...

The structure and the solidification of gold nanoparticles in a carbon nanotube are investigated using molecular dynamics simulations. The simulations indicate that the predicted solidification temperature of the enclosed particle is lower than its bulk counterpart, but higher than that observed for clusters placed in vacuum. A comparison with a phenomenological model indicates that, in the con...

A multi-phase field model for quantitative simulations of polycrystalline solidification of binary alloys is introduced. During the freegrowth stage of solidification, the model exploits the thin-interface analysis developed by Karma [3] in order to realistically capture bulk phase diffusion and the sharp interface corrections predicted by traditional models of solidification. During grain boun...

The process of cast explosive solidification molding has been dynamic monitored by multi-channel ultrasonic transmission method. It presents the regular pattern of ultrasonic attenuation, velocity and waveform in this process. The results show that velocity values and waveform are relative to solidification speed and physical characterization on the phase border, and ultrasonic attenuation is r...

Cementation of aqueous radioactive waste contaminated with a significant 90Sr is challenging due to the potential radiolysis water contents. Utilization calcium aluminate cement (CAC) modified sodium polyphosphate (CAP) interesting as its content can be reduced by thermal treatment. The present study investigated solidification and stabilization Sr2+ Cl− ions in CAC CAP or without A leaching te...

Abstract Remediation of soil contaminated with per- and polyfluoroalkyl substances (PFAS) is critical due to the high persistence mobility these compounds. In this study, stabilization solidification (S/S) treatment was evaluated at pilot-scale using 6 tons PFAS-containing aqueous film-forming foam. At pilot-scale, long-term PFAS removal over years precipitation (simulated irrigation) in leacha...

conclusions the trunk stabilization exercises are more effective than conventional back care exercises in the rehabilitation of patients with chronic lbp. results the results of the study demonstrated significant improvements in abdominal muscle endurance and reduction in vas and modq score of both groups (p = 0.001). the trunk stabilization exercise group showed greater gains in abdominal musc...
