Abstract: Dyes in wastewater are of particular environmental concern since they give an undesirable color to the waters, dye and their derivatives are harmful to human health and the environment ( Annadurai et al., 2002). Due to their biological persistency, conventional biological treat-ment processes such as activated sludge process are ineffective for their removal(Shaul et al., 1991). There is a need to develop effective methods for the degradation of such persistent organic pollutants, either to less harmful compounds or, more desirable, to their complete mineralization.

Abstract: The reed pulping black liquor is used as a sample. Researches of (1) combined effect of ultrasound(US)/polyferric sulphate(PFS)/hydrogen peroxide(H 2O 2); (2) effects of the horn tip areas; (3) effect of dose of PFS were carried. Extrapolation of these experiments indicated treatment results are possibly related to complex chemical compositions in the reed pulping black liquor.

Abstract: Reported seagrass bed losses have led to increased awareness of the need for seagrass bed restoration, and seeds have potential for this restoration. In this paper, we systematically review the research and application of seagrass seeds in recent years. The morphology, development, dispersal, dormancy and germination of seagrass seeds are summarized and compared from the viewpoint of seed biology and seed ecology. We propose that when natural seagrass seed banks are researched, it is also necessary to establish artificial seagrass seed banks based on research of seed biology and seed ecology, which will guide seed collection and preservation. Seeding method and the approach of restoration using seeds are discussed, and we also point out problems existing in current research and application. In conclusion, we project expectations of the future in the research and application of seagrass seeds, and we forecast that seagrass seed ecology research will be an emphasis in the future. In the application area, research should focus on increasing the seed germination rate and seedling rate, and the problem of low seedling survival rate must be solved if artificial seedlings grown from seeds are to be utilized to restore seagrass beds.
Dynamical behaviors of hydrodynamic cavitation bubble under ultrasound field

Shen Zhuang-Zhi,Lin Shu-Yu,

物理学报 , 2011,
Abstract: Considering liquid viscosity, surface tension, liquid compressibility and turbulence, the dynamical behaviors of cavitation bubble in venturi cavitation reactor are numerically investigated with using acoustic field regarding water as a work medium. The effects of acoustic frequency, acoustic pressure and ratio of throat to pipe diameter on cavitation bubble dynamics, bubble temperature and pressure pulse by rapid collapse of cavitation bubble are analysed. The results show that bubble motion of hydrodynamic cavitation modulated by ultrasound, becomes the high energy stable cavitation. It is favorable for enhancing the cavitation effect.
Dynamic behavior of a cavitation bubble in acoustic field and electric field

Shen Zhuang-Zhi,Wu Sheng-Ju,

物理学报 , 2012,
Abstract: The dynamics of a cavitation bubble under acoustic field and an electric field is studied by regarding liquid as a working medium. The effects of the dimensionless frequency and strength of acoustic field and electric field on cavitation bubble dynamical behaviors by Rayleigh-Plesset equation are numerically investigated. The results show that when acoustic field and electric field are combined, chaos area range of cavitation bubble motion is larger than that when only acoustic field or single electric field exists. This is of significance not only for further research of acoustic cavitation but also for enhancing and improving the cavitation degration of organic pollutant technology.
Chaotic characteristics of gas bubble motion in acoustic field

Shen Zhuang-Zhi,Lin Shu-Yu,

物理学报 , 2011,
Abstract: Considering liquid compressibility, the dynamical behaviors of gas bubble in acoustic field are investigated by regarding water as a work medium. The effects of acoustic frequency, acoustic pressure, initial radius of gas bubble, liquid surface tension, and viscosity coefficient on bubble motion state are numerically simulated. The relationship between cavitation treatment effect and gas bubble motion state is analysed.The results show that when the gas bubble motion is in a chaotic state, it is the most important factor for enhancing acoustic cavitation degradation of organic pollutants ability.

Abstract: To study the physiological basis of tomato breeding for resistant to bacterial wilt,we inoculated the resistant and susceptible tomato cultivars with the pathogen bacterium to reveal the dynamic changes in the activities of four enzymes in plants of different cultivars in relation to their resistance.The results showed that the phenylanine ammonia lyase(PAL) activity of 'T51A',a resistant cultivar,was higher than that of the control(CK),while for 'T9230',a susceptible one,the activity was at about the similar level as the control(CK) following their infection by Ralstonia solanacearum.The resistant cultivar exhibited higher activity of superoxide dismutase(SOD) than the control(CK),with the peak value increased by 16.12%.But the susceptible cultivar was inferior to the CK,with the peak value decreased by 25.14%.The activity of peroxidase(POD) and polyphenoloxidase(PPO) did not differ significantly between resistant and susceptible cultivar.The capacity of the resistant cultivar in inhibiting chlorophyll disintegration and maintaining higher carotenoid content was significantly stronger than that of the susceptible cultivar.
