2,2',3,3',4,4',5,5',6,6'-bromdiphenyl ether (BDE-209) solutions were irradiated with ultraviolet (UV) and electron beams. Organic compounds were fully removed by each type of radiation. The absorbed energy of the ionizing radiation (electron beams) needed for removal was much lower than that of UV photocatalysis. BDE-209 removal using the ionizing radiation was accelerated drastically by dosage. It is suggested that pH value of solution affect the decomposition rates. Radiolysis with the high pH value showed consistently high rate and high efficiency of BDE-209 removal.

(+)-alpha-phenylglycine are significant contaminants at pharmaceutical intermediates production. To study processes for the destruction of contaminant L(+)-alpha-phenylglycine in acid aqueous solution we have investigated the transient species using both laser flash photolysis. The OH· reaction with L(+)-alpha-phenylglycine process was investigated and formed polymer. Furthermore, the results of steady-state analysis suggested that L(+)-alpha-phenylglycine removal was found to be more efficient with increasing applied dose. L(+)-alpha-phenylglycine, decreased by 44.50%, using a dose of 14kGy.

The batch removal of dye from textile dyeing wastewater by using nanooxides decorated multiwalled carbon nanotubes was studied under electron beam conditions. The effect of different nanooxides decorated multiwalled carbon nanotubes content and irradiation dosage was also investigated. The color removal efficiency was 94.9% in dose of 17.5kGy. The colour removal efficiency with Fe2O3 decorated multiwalled carbon nanotubes was similar to with TiO2 decorated multiwalled carbon nanotubues. The COD removal efficiency was 52.5% in the dose of 14.0kGy. When the irradiation dose of 17.5kGy, the COD removal efficiency was 98.2% with TiO2 decorated multiwalled carbon nanotubes.Overall, the study demonstrated that nanooxides decorated multiwalled carbon nanotubes can effectively remove color and COD from aqueous solution under irradiation.

Several research groups are using the Yangtze field vole as a model for studying schistosome infection, but relatively little is known about the species's reproductive physiology. The authors examined the vole's in vivo and in vitro embryonic development as well as the efficacy of in vitro fertilization using either fresh or cryopreserved sperm to breed these rodents.

Abstract: For the single-particle potential surface of the two-center shell model, two geometrical quantities which determine the local Liapunov exponents are derived. It is shown that the appearance of a large positive local Liapunov exponent in a large area of the coordinate space leads to the quantum chaotic motion of a single particle in heavy nuclei. For both small and large (or medium) separations of the two centers, the dependence of the quantum chaotic motion on the neck deformation is interpreted from the dynamical point of view.

The analytical expression of the propagator is obtained by using lie algebra method. The fission rates at the saddle point in both the constant and the coordinate-dependent mass, friction and temperature cases are calculated based on the formulae of the propagator and local approximation. The numerical calculation for240Pu shows the fission rates from our method are reasonable.

The propagator method is efficient in solving the Fokker-Planck equation with an inharmonic oscillator potential. The propagator is derived by using the Lie algebra method. The fission rate of is calculated based on the expression of the propagator. The numerical results show that the rate is reasonable.

The novel properties of the environment are found in independent oscillator model. 1) If the initial state of the composite system lies in thermal equilibrium, then the environment is equipartition of energy, which, however, is moving with the system. 2) When the environment is in thermal equilibrium, but the system deviates from it at the beginning, the environment is no longer equipartition of energy, but which still moves with the system. These properties are quite different from those of the collection of oscillators discussed by Ford et al. (see Ref. [9])

The single particle-energy levels of U92238as a function of cranked frequency are given in rotating two-centre shell model. It is found that the curvature distribution approaches the prediction of Gaussian unitary ensemble (GUE) [14] for a certain range of separations between two centers at some cranked frequencies, which is the first support to the prediction in the realistic and complex system like heavy nuclei. Meanwhile, we find that the spacing distributions for various separations have a similar structure when the frequency is high, for which a formulae is suggested to describe this kind of spacing distributions. In addition, we compute the spectral rigidity characterizing the long range correlation of a spectrum.
