Catalytic particle electrodes (CPEs) were developed from steel slag waste, and were used to degrade Rhodamine B (RhB). To improve degradation efficiency, Mn-loaded CPEs with good reproductive performance were constructed through ultrasound impregnation–calcination strategy. The resulting samples were characterized by XRF, SEM, EDS, XPS and XRD. Degradation efficiency of the systems with Mn-loaded CPEs were 93.22% without air supply in 80 min. And degradation efficiency for Mn-loaded CPEs reached 100% with air supply in 50 min. Furthermore, the enhanced mechanism was proposed. The high degradation efficiency could be ascribed to the increase of hydroxyl radicals originated from electro-Fenton.

The neuronally expressed developmentally downregulated 4 (NEDD4) gene encodes a ubiquitin ligase that targets the epithelial sodium channel for degradation and has been implicated in tumor growth in various cancers. Hence, in this study, we intended to characterize the functional relevance of the NEDD4-mediated Kruppel-like factor 8/microRNA-132/nuclear factor E2-related factor 2 (KLF8/miR-132/NRF2) axis in the development of bladder cancer. NEDD4 and KLF8 were overexpressed in bladder cancer tissues and were associated with poorer patient survival rates. In bladder cancer cells, NEDD4 intensified the stability and transcriptional activity of KLF8 through ubiquitination to augment cell viability and migratory ability. Our investigations revealed that NEDD4 promotes the binding of KLF8 to the miR-132 promoter region and inhibits the expression of miR-132. KLF8 inhibited the expression of miR-132 to augment the viability and migratory ability of bladder cancer cells. Furthermore, miR-132 downregulated the expression of NRF2 to restrict the viability and migratory ability of bladder cancer cells. In addition, in vivo findings verified that NEDD4 regulates the KLF8/miR-132/NRF2 axis by accelerating tumor growth and lung metastasis. In conclusion, this study highlights NEDD4 as a potential therapeutic target against tumor recurrence and metastasis in bladder cancer.

A novel continuous-flow electrochemical reactor was designed for oilfield wastewater advancedtreatment. Magnetic steel slag particles were prepared as particle electrodes in the reactor. The bestpreparation condition of steel slag particle electrodes is obtained via orthogonal and single factorexperiments. The resulting samples were characterized by scanning electron microscope and vibratingsample magnetometer. It was demonstrated that saturation magnetic intensity of the particle was1.6389 emu/g. The process parameters and the total organic carbon (TOC) removal kinetics wereinvestigated. Result showed that the reactor could remove over 85% TOC in 2 h, which was considered tobe effective.

A wavelength-independent optical sensor based on an asymmetric Mach-Zehnder interferometer (AMZI) is proposed. The optical sensor based on an AMZI is very sensitive to wavelength, and wavelength drift will lead to measurement error. The optical sensor is compensated to reduce its dependence on wavelength. The insensitivity of the optical sensor to wavelength mainly depends on the compensation structure, which is composed of an AMZI cascaded with another AMZI and can compensate the wavelength drift. The influence of wavelength drift on the optical sensor can be counteracted by carefully designing the size parameters of the compensation structure. When the wavelength changes from 1549.9 nm to 1550.1 nm, the error after compensation can be lower than 0.066%. Furthermore, the effect of fabrication tolerance on compensation results is analyzed. The proposed compensation method can also be used to compensate the drift of other parameters such as temperature, and can be applied to the compensation of other interference-based optical devices.

The phytophagous caterpillar Illiberis ulmivora is a serious pest of Ulmus glaucescens Franch (Ulmaceae, Ulmus). In order to test potent sex attractant, field trails of synthetic candidate attractants were conducted in China. In this study, baits with ternary blends, (2S)-butyl (7Z)-dodecenoate, (2S)-butyl (9Z)-tetradecenoate, and (2S)-butyl (5Z)-decenoate (8:4:1 ratio) resulted in a higher number of male moths capture than the rest of the baits that were offered. Traps positioned at a height of 1.2 m attracted more males than those installed at heights of 2.2 m and 3.2 m. The slope aspect, temperature and humility had a significant effect on the trap catches. More catches occurred in traps placed on semi-shady and semi-sunny slopes than those placed on sunny and shady slopes. The number of pheromones in the septa decreased with age. The residual amounts of pheromones in the lures combined with 2,6-di-tert - butyl-p-cresol (BHT) were higher than those in the control. However, there were no differences in the male captures between components and components combined with BHT during the first 8 d. These findings on monitoring and trap positions can be used to predict the occurrence and population dynamics of I. ulmivora, to develop ecological management of I. ulmivora.

The purpose of this thesis is to develop a double cylinder synchronization control system to address the high precision control requirement of this system. First, the dual-input dual-output coupling mathematical model of the hydraulic press synchronization control system was built using mechanism modelling. Then, the mathematical model of compensating and decoupling links is established by the input and load disturbance decoupling control method based on feedback compensation. Next, a cross-coupled fuzzy PID controller is designed, which is then combined with full decoupling compensation method. Finally, the coupling characteristics of the synchronization control system and the synchronization control performance of the hydraulic cylinders under the cross-coupled fuzzy PID controller combined with the decoupling control algorithm were tested and evaluated in a principle experiment platform. The results indicate that the robustness and the ability to resist interference load are improved under the theory and control strategy outlined in this paper.
