Crop consumptive water use is recognized as a key element to understand regional water management performance. This study documents an attempt to apply a regional evapotranspiration model（SEBAL） and crop information for assessment of regional crop（summer maize and winter wheat） actual evapotranspiration（ET a） in Huang-Huai-Hai（3H） Plain, China. The average seasonal ET a of summer maize and winter wheat were 354.8 and 521.5 mm respectively in 3H Plain. A high-ET a belt of summer maize occurs in piedmont plain, while a low ET a area was found in the hill-irrigable land and dry land area. For winter wheat, a high-ET a area was located in the middle part of 3H Plain, including low plain-hydropenia irrigable land and dry land, hill-irrigable land and dry land, and basin-irrigable land and dry land. Spatial analysis demonstrated a linear relationship between crop ET a, normalized difference vegetation index（NDVI）, and the land surface temperature（LST）. A stronger relationship between ET a and NDVI was found in the metaphase and last phase than other crop growing phase, as indicated by higher correlation coefficient values. Additionally, higher correlation coefficients were detected between ET a and LST than that between ET a and NDVI, and this significant relationship ran through the entire crop growing season. ET a in the summer maize growing season showed a significant relationship with longitude, while ET a in the winter wheat growing season showed a significant relationship with latitude. The results of this study will serve as baseline information for water resources management of 3H Plain.

The title complexes [Dy（p-NBA）3Phen]2-3H2O（Ⅰ） and [Dy（m-NBA）3Phen]2·4H2O（Ⅱ） were synthesized, in the two molecular formulas of which NBA is nitrobenzoate and Phen is 1,10-phenanthroline. The characterizations of the complexes were carried out by means of elemental analysis, UV, IR, XRD and molar conductivity. The thermal decomposition of the two complexes were studied under the non-isothermal condition by DSC, TG-DTG and IR methods in detail. The kinetic parameters of the dehydration process were also obtained by the analysis of DSC curves of the two complexes with Popescu and Vyazovkin methods, respectively.

AIM:To investigate the protective effect of heme oxygenase-1(HO-1)against H_(2)O_(2)-induced apoptosis in human ARPE-19 ***:The lentiviral vector expressing HO-1 was prepared and transfected into apoptotic ARPE-19 cells induced by H_(2)O_(2).Functional experiments including cell counting kit-8(CCK-8)assay,flow cytometry(FCM)and mitochondrial membrane potential assay were ***:The ultrastructure of ARPE-19 cells was observed using transmission electron microscope(TEM).It was found that exogenous HO-1 significantly ameliorated H_(2)O_(2)-induced loss of cell viability,apoptosis and intracellular levels of reactive oxygen species(ROS)in ARPE-19 *** overexpression of HO-1 facilitated the transfer of nuclear factor erythroid-2-related factor 2(Nrf2)from cytoplasm to nucleus,which in turn upregualted expressions HO-1 and B-cell lymphoma-2(Bcl-2).Furthermore,HO-1 upregulation further inhibited H_(2)O_(2)-induced release of cysteinyl aspartate specific proteinase-3(caspase-3).CONCLUSION:Exogenous HO-1 protect ARPE-19 cells against H_(2)O_(2)-induced oxidative stress by regulating the expressions of Nrf2,HO-1,Bcl-2,and caspase-3.

As has been extensively reported by hydraulic engineers in China, the flow of hyperconcentrated fluid mud in rivers is often pulsating and appears as roll waves. We report here two theories for such pulsating flows besed on two constitutive laws: the power law and Bingham plastic law. In order to account for the nonlinear bores convective inertia is kept in the approximate long wave equations. Kar man's momentum integral method with an assumed velocity profile is then employed. Results of the linearized instability analyses are *** bores are obtained either as stationary wave solutions or as the long- time limit of unstable disturbances which are initially infinitesimal. Implications on ho scour is examined.
