Ce6-xHoxMoO15-δ（0.0≤x≤1.2） was synthesized by modified sol-gel method and characterized by differential X-ray diffraction（XRD）, Raman, and X-ray photoelectron spectroscopy（XPS） methods. The oxide ionic conductivity of the samples was investigated by AC impedance spectroscopy. It shows that all the samples are single phase with a cubic fluorite structure. The solid solution Ce6-xHoxMoO15-δ（x=0.6） was detected to be the best conducting phase with the highest conductivity（σ1=1.05×10^-2 S/cm） at 800 ℃ and the lowest activation energy（Ea=1.09 eV）. These properties suggest that this kind of material has a potential application in intermediate-low temperature solid oxide fuel ceils.

Landscape design for a green community should be favorable for the ambient ecological environment and for enhancement of both the local climate of a residential area and the environmental quality of life. This paper presents optimization methods for plant landscape design that take account of results of comparisons of noise reduction effects, heat island temperature decreases and effects on ventilation. These methods are based on different plant configurations and various luminous environments, such as exterior sunshine and shaded areas after the simulation of exterior luminous, acoustic and thermal environments of a residential area using the analytic software ECOTECT, CADNA/A, and PHEONICS. Three different types of residential buildings are simulated including a faculty apartment in the Xixi Campus of Zhejiang University, the Huaqing Villa and the Gangwan Jiayuan faculty apartment of Zhejiang University, China, based on green building design theory. In addition, the methods and process flow of landscape design of green residential areas are also described for the improvement of the exterior physical living environment.

Aim: To investigate the anticancer effects and the molecular mechanisms of deguelin on human U937 leukemia cells, and to explore the underlying mechanism regulating nucleoporin 98 （Nup98） and nucleoporin 88 （Nup88） in vitro. Methods: The effects of deguelin on the growth of U937 cells were studied by MTT assay. The effect of deguelin on the cell cycle of U937 cells was studied by using a propidium iodide method. The localization of the nuclear pore complex proteins Nup98 and Nup88 was investigated by using immunofluorescence and immunoelectron microscopy. The expression of Nup98 and Nup88 in U937 cells was investigated by using flow cytometry and Western blot. Results: The prolif eration of U937 cells was inhibited in the deguelin-treated group, with a 24-h IC50value of 21.61 nmol/L and a 36-h IC50value of 17.07 nmol/L. U937 cells treated with deguelin had reduced percentages of cells in the G0/G1phase, whereas cells accumulated in the S and G2/M phases. Nup88 and Nup98 were found on both the nuclar and cytoplasmic sides of the U937 cells by using immunofluorescence and immunoelectron microscopy. The expression of Nup98 was upregulated and that of the Nup88 protein was downregulated in U937 cells treated with deguelin. Conclusion: Deguelin is able to inhibit the proliferation of U937 cells by regulating the cell cycle such that cells are arrested at the S and G2/M phases, so that the proportion of cells in the G0/G1phase decreases. The antitumor effects of deguelin are related to upregulating the expression of Nup98 and downregulating the expression of Nup88 protein in U937 cells.

The bulk viscosity of interacting strange quark matter in a strong external magnetic field B m with a real equation of state is *** is found that interquark interactions can significantly increase the bulk viscosity,and the magnetic field B_(m) can cause irregular oscillations in both components of the bulk viscosity,ξ||(parallel to B_(m))and ξ⊥(perpendicular to B_(m)).A comparison with non-interacting strange quark matter reveals that when B_(m) is sufficiently large,ξ⊥is more affected by interactions than ξ||.Additionally,the quasi-oscillation of the bulk viscosity with changes in density may facilitate the for-mation of magnetic ***,the resulting r-mode instability windows are in good agreement with observational data for compact stars in low-mass X-ray ***,the r-mode instability window for interacting strange quark matter in high magnetic fields has a minimum rotation frequency exceeding 1050 Hz,which may explain the observed very high spin frequency of a pulsar with V=1122 Hz.
