| 1 | The integration of methanogenesis with denitrification and anaerobic ammonium oxidation in an expanded granular sludge bed reactor显示文摘The integration of methanogenesis with denitrification and anaerobic ammonium oxidation(ANAMMOX) was studied in an expanded granular sludge bed(EGSB) reactor in this work. Experimental results from the continuous treatment of wastewater with nitrite and ammonium, which lasted for 107 days, demonstrated that wastewater with high nitrite and ammonium could be anaerobically treated in an expanded granular sludge bed reactor. More than 91% to 97% of COD were removed at up to about 3.9 g COD/(L·d) of COD volumetric loading rate. More than 97% to 100% of nitrite was denitrified at up to about 0.8 g NO -2-N/(L·d), which is 16 times higher than that in a conventional activated sludge system with nitrification/denitrification(0.05 gN/(L·d)). No dissimilatory reduction of nitrite to ammonium occurred in the process. However, maximum of about 40% ammonium was found to be lost. Batch tests of 15 days with sludge from the reactor showed that 100% of nitrite was denitrified completely, and about 3% of ammonium was removed when only ammonium (34.3 mg/L) and nitrite(34.3 mg/L) were added into the sludge suspension medium. Furthermore, about 15% of ammonium amounts were lost with organic COD addition. It suggested that the methanogenesis in the system could enhance ANAMMOX because of intermediate hydrogen produced during methanogenesis. | ZHANG Dai-jun 1,2 (1.

| 2 | Dissimilatory Fe(Ⅲ) reduction characteristics of paddy soil extract cultures treated with glucose or fatty acids显示文摘Dissimilatory Fe(Ⅲ) reduction is a universal process with irreplaceable biological and environmental importance in anoxic environments. Our knowledge about Fe(Ⅲ) reduction predominantly comes from pure cultures of dissimilatory Fe(Ⅲ) reducing bacteria (DFRB). The objective of this study was to compare the effects of glucose and a selection of short organic acids (citrate, succinate, pyruvate, propionate, acetate, and formate) on Fe(Ⅲ) reduction via the anaerobic culture of three paddy soil solutions with Fe(OH)3 as the sole electron acceptor. The results showed significant differences in Fe(Ⅲ) reduction among the three paddy soil solutions and substrate types. Bacteria from the Sichuan paddy soil responded quickly to substrate supply and showed higher Fe(Ⅲ) reducing activity than the other two soil types. Bacteria in the Jiangxi paddy soil culture solution could not use propionate as a source of electrons for Fe(Ⅲ) reduction. Similarly, bacteria in the Jilin paddy soil culture could not use succinate effectively. Pyruvate was readily used by cultures from all three paddy soil solutions, thus indicating that there were some similarities in substrate utilization by bacteria for Fe(Ⅲ) reduction. The use of glucose and citrate as substrate for dissimilatory Fe(Ⅲ) reduction indicates important ecological implications for this type of anoxic respiration. | HE Jiangzhou1,2, QU Dong1, 1.

| 5 | Copper Adsorption on Olivine显示文摘Copper adsorption on olivine supplied by the A/S Olivine Production Plant at Aheim in western Norway was studied. The factors were evaluated which affect the uptake of copper. It is shown that the equilibrium pH of aqueous solution has the greatest influence on copper adsorption thanks to the competitive adsorption between proton and copper ions, and the adsorption of copper to olivine increases rapidly with pH increasing from 4 to 6. Moreover, initial copper concentration and olivine dose possess significant effect on copper adsorption, for the adsorption rate of copper increases with olivine dose increasing or initial copper concentration decreasing at the same pH. In addition, the ionic strength effect on the adsorption was also investigated, but it owns little effect on the adsorption process of copper due to the formation of inner sphere adsorption of copper on olivine. The experimental data show that olivine has a high acid buffer capacity and is an effective adsorbent for copper. | Lei Shao, Rolf A. Kleiv, Kunt L.

| 6 | Effects of Microtubule Polymerization Inhibitor on the Hypersensitive Response of Wheat Induced by the Non-Host Pathogen Sphaerotheca fuliginea显示文摘The plant cytoskeleton is a highly dynamic and versatile intracellular scaffold composed of microtubules and microfilaments, serving a multiplicity of functions in plant cells. To reveal the relationship between the cytoskeleton in wheat (Triticum aestivum L.) cv. Suwon 11 attacked by the non-host pathogen Sphaerotheca fuliginea and the initiation of the hypersensitive response, the microtubule inhibitor oryzalin was injected into the wheat leaves immediately prior to inoculation. The incidence of hypersensitive cell death was significantly lower than that in water-treated control. In addition, the occurrence of hypersensitive cell death was also delayed and S. fuliginea was able to penetrate and form haustoria in epidermal tissues of wheat. All the results above indicated that hypersensitive cell death was associated with depolymerisation of microtubules, suggesting that microtubules might play an important role in the expression of non-host resistance of wheat. | LI Hong-li, WANG Hai-yan, HAO Xin-yuan, SONG Xiao-he and MA Qing College of Plant Protection and Shaanxi Key Laboratory of Molecular Biology for Agriculture, Northwest A&F University/Key Laboratory of Plant Protection Resources and Pest Management, Ministry of Education, Yangling 712100, P.R.China | 2010 | Agricultural Sciences in China2010，9，3： | 3 |
| 7 | Using soil surface gray level to determine surface soil water content显示文摘How to determine surface soil water content(SWC) quickly and accurately is fundamental in studying eco-hydrological processes and their modeling.Here we use laboratory experiments to determine surface SWC using soil surface gray level(SGL) values.A negatively exponential relationship exists between SGL and SWC,i.e.,SGL increases with the decrease of SWC.SGL can be estimated based on initial SGL value(surface gray level when SWC=0),SWC,and a surface roughness coefficient characterized by mean soil particle size.The variation range of SGL was larger than that of SWC,indicating that changes in SWC were enhanced in SGL,and that SGL would thus be sensitive to changes in soil water.At the 95% confidence level,SWC can be determined by using the relationship between SWC and SGL established by the experiments.The determination of SWC has a high precision when SWC was between dry and saturated. | ZHU YuanJun1,2,WANG YunQiang1,2 & SHAO MingAn1,2 1 State Key Laboratory of Soil Erosion and Dryland Farming on Loess Plateau,Institute of Soil and Water Conservation,Northwest A & F University,Yangling 712100,China 2 Institute of Soil and Water Conservation,Chinese Academy of Sciences & Ministry of Water Resources,Yangling 712100,China | 2010 | Science China Earth Sciences2010，53，10： | 2 |

| 12 | A Bionic Approach for Topology Optimization for Tension-only or Compression-only Design显示文摘A new bionic approach is presented to find the optimal topologies of a structure with tension-only or compression-onlymaterial based on bone remodelling theory.By traditional methods,the computational cost of topology optimization of thestructure is high due to material nonlinearity.To improve the efficiency of optimization,the reference-interval with material-replacement method is presented.In the method,firstly,the optimization process of a structure is considered as bone remodellingprocess under the same loading conditions.A reference interval of Strain Energy Density (SED),corresponding to thedead zone or lazy zone in bone mechanics,is adopted to control the update of the design variables.Secondly,a material-replacement scheme is used to simplify the Finite Element Analysis (FEA) of structure in optimization.In the operation ofmaterial-replacement,the original tension-only or compression-only material in design domain is replaced with a new isotropicmaterial and the Effective Strain Energy Density (ESED) of each element can be obtained.Finally,the update of design variablesis determined by comparing the local ESED and the current reference interval of SED,e.g.,the increment of a relativedensity is nonzero if the local ESED is out of the current reference interval.Numerical results validate the method. | Kun Cai,Jiao ShiCollege of Water Resources and Architectural Engineering,Northwest A&F University,Xianyang 712100,P.R.China | 2010 | Journal of Bionic Engineering2010，7，4： | 1 |

| 14 | ADSORPTION OF LATERALLY INTERACTING 1-NAPHTHOL/1-NAPHTHYL-AMINE MIXTURES ON NONPOLAR SURFACES FROM AQUEOUS SOLUTIONS显示文摘The binary adsorption behavior of 1-naphthol/1-naphthylamine mixtures in water on nonpolar adsorbent Amberlite XAD4 was investigated at 293 K,303 K and 313 K,respectively.The experimental uptakes of 1-naphthol and l-naphthylamine in all binary-component systems of different molar ratios were obviously higher than the corresponding uptakes predicted by the extended Langmuir model,assuming no interaction between the adsorbed molecules of the two components.This phenomenon was attributed to the cooperative adsorption effect arising from the hydrogen bonding interaction between l-naphthol and l-napbthylamine molecules.A modified extended Langmuir model was proposed to describe the binary adsorption behavior by means of introducing a fitting parameter related with the cooperative adsorption effect of the adsorbates. | Wei-ming Zhang Jin-long Chen Qun Chen Ming-yang He Bing-cai Pan and Quan-xing Zhang a State Key Laboratory of Pollution Control and Resources Reuse,School of the Environment,Nanjing University,Nanjing 210093,China b Research Center for Engineering Technology of Organic Poison Control and Resources Reuse in Jiangsu Province,Nanjing 210038,China c Department of Chemical Engineering,Jiangsu Polytechnic,Changzhou 213016,China | 2006 | Chinese Journal of Polymer Science2006，24，1： | 1 |
| 15 | Early Ordovician Sea Level Changes in South China and Their Worldwide Correlation显示文摘The sea level changes and their correlation from the latest Cambrian C. proavus zone to the Ordovician N. gracilis zone in South China are discussed on the basis of the Ordovician paleogeographic reconstruction in China. The study of sequence, biostratigraphy and ecostratigraphy suggests that at least 8 major regressive events, occurring in the following levels: basal H. simplex zone (RE1), near the base of C. intermedius zone (RE2), basal C. angulatus zone (RE3), near Mid/Upper G. quadriplicatus zone (RE4) and succeeding the first phase (RE4a) of RE4 at basal P. deltifer zone, Kiaerograptus/Brygograptus zonal boundary (RE5), end S.diversus-P.proteus A. Z.(RE6), end P. originalis zone (RE7) and Early H. teretiusculus or end P. serra zone (RE8), can be recognized in the cratonic plat- form and its shelf-slope tracts of the South China plate based on sequence change or disconformity and associated breaks in biological succession. Most of them can be traced in the other plates or continents. | Wang Xiaofeng (Yichang Institute of Geology and Mineral Resources, CAGS, Yichang 443003) Li Zhiming Chen Jianqiang (Department of Geology and Mineral Resources, China University of Geosciences, Beijing 100083) Chen Xiaohong (Yichang Institute of Geology a | 1996 | Journal of Earth Science1996，15，1： | 1 |
| 16 | Development Plan of East Unity Oil Field, Sudan, Using Reservoir Simulation Study显示文摘Simulation study was applied in the development planning of East Unity oil field, Sudan. A grid consisting of 2 000 cells was constructed. A major challenge of the study was to evolve a full field development and future reservoir management strategy that would ensure maximum recovery of oil based on well Un51.

| 18 | EFFECT OF WEAK INTERACTIONS ON PHENOL ADSORPTION FROM AQUEOUS SOLUTIONS BY AMINATED POLYMERIC ADSORBENTS显示文摘Adsorption behaviors of phenol from aqueous solutions have been investigated in batch systems at 303 K and 318 K respectively,using hypercrosslinked polymeric adsorbent(CHA111),aminated hypercrosslinked polymeric adsorbents (NDA101,NDA103,NDA105)and weakly basic polymeric adsorbent(D301)with a view to studying the effect of hydrogen bonding and Van der Waals interactions between adsorbate and the adsorbent.All adsorption isotherms can be well fitted by Langmuir and Freundlich equations.Compared with D301 driven by hydrogen bonding interaction only and CHA111 driven by Van der Waals interaction only,phenol adsorption on aminated adsorbents driven by both hydrogen bonding and Van der Waals interactions were apparently different,i.e.,negative effect for NDA105,positive effect for NDA101 and synergistic effect for NDA103.In this synergistic action,some weak interactions would contribute more or less to the adsorption than they work individually. | Wei-ming Zhang Jin-long Chen Ai-min Li Bing-cai Pan Qun Chen Ming-yang He and Quan-xing Zhang a State Key Laboratory of Pollution Control and Resources Reuse,School of the Environment,Nanjing University,Nanjing 210093,China b Research Center for Engineering Technology of Organic Poison Control and Resources Reuse in Jiangsu Province,Nanjing 210038,China c Department of Chemical Engineering,Jiangsu Polytechnic University,Changzhou 213016,China | 2006 | Chinese Journal of Polymer Science2006，24，1： | 0 |
