| 2 | Potential of Industrial Byproducts in Ameliorating Acidity and Aluminum Toxicity of Soils Under Tea Plantation显示文摘It is imperative to choose some low cost,available and effective ameliorants to correct soil acidity in southern China for sustainable agriculture.The present investigation dealt with the possible role of industrial byproducts,i.e.,coal fly ash(CFA),alkaline slag(AS),red mud(RM) and phosphogypsum(PG) in correcting acidity and aluminum(Al) toxicity of soils under tea plantation using an indoor incubation experiment.Results indicated that CFA,AS and RM increased soil pH,while PG decreased the pHs of an Ultisol and an Alfisol.The increment of soil pH followed the order of RM > AS > CFA.All the industrial byproducts invariably decreased exchangeable Al and hence increased exchangeable Ca,Mg,K and Na and effective cation exchange capacity.RM,AS and lime decreased total soluble Al,exchangeable Al and organically bound Al.Formation and retention of hydroxyl-Al polymers were the principal mechanism through which Al phytotoxicity was alleviated by application of these amendments.In addition,the heavy metal contents in the four industrial byproducts constituted a limited environmental hazard in a short time at the rates normally used in agriculture.Therefore,the short-term use of the byproducts,especially AS and RM,as amendments for soil acidity and Al toxicity in acid soils may be a potential alternative to the traditional use of mined gypsum and lime. | LI Jiu-Yu WANG Ning XU Ren-Kou D.

| 4 | Ozone sensitivity analysis with the MM5-CMAQ modeling system for Shanghai显示文摘Ozone has become one of the most important air pollution issues around the world. This article applied both O 3 /(NOy-NOx) and H 2 O 2 /HNO 3 indicators to analyze the ozone sensitivity in urban and rural areas of Shanghai, with implementation of the MM5-CMAQ modeling system in July, 2007. The meteorological parameters were obtained by using the MM5 model. A regional emission inventory with spatial and temporal allocation based on the statistical data has been developed to provide input emission data to the MM5-CMAQ modeling system. Results showed that the ozone concentrations in Shanghai show clear regional differences. The ozone concentration in rural areas was much higher than that in the urban area. Two indicators showed that ozone was more sensitive to VOCs in urban areas, while it tended to be NOx sensitive in rural areas of Shanghai. | Li Li Changhong Chen Cheng Huang Haiying Huang Gangfeng Zhang Yangjun Wang Minghua Chen Hongli Wang Yiran Chen D.

| 7 | Temporal Variability in Soil CO_2 Emission in an Orchard Forest Ecosystem显示文摘Temporal variability in soil CO2 emission from an orchard was measured using a dynamic open-chamber system for measuring soil CO2 efflux in Heshan Guangdong Province, in the lower subtropical area of China. Intensive measurements were conducted for a period of 12 months. Soil CO2 emissions were also modeled by multiple regression analysis from daily air temperature, dry-bulb saturated vapor pressure, relative humidity, atmospheric pressure, soil moisture, and soil temperature. Data was analyzed based on soil moisture levels and air temperature with annual data being grouped into either hot-humid season or relatively cool season based on the precipitation patterns. This was essential in order to acquire simplified exponential models for parameter estimation. Minimum and maximum daily mean soil CO2 efflux rates were observed in November and July, with respective rates of 1.98 ± 0.66 and 11.04 ± 0.96 μmol m-2 s-1 being recorded. Annual average soil CO2 emission (FCO2) was 5.92 μmol m-2 s-1. Including all the weather variables into the model helped to explain 73.9% of temporal variability in soil CO2 emission during the measurement period. Soil CO2 efflux increased with increasing soil temperature and soil moisture. Preliminary results showed that Q10, which is defined as the difference in respiration rates over a 10 -C interval, was partly explained by fine root biomass. Soil temperature and soil moisture were the dominant factors controlling soil CO2 efflux and were regarded as the driving variables for CO2 production in the soil. Including these two variables in regression models could provide a useful tool for predicting the variation of CO2 emission in the commercial forest soils of South China . | LI Yue-Lin D. OTIENO K.

| 8 | Hierarchical activation of compartmentalized pools of AMPK depends on severity of nutrient or energy stress显示文摘AMPK, a master regulator of metabolic homeostasis, is activated by both AMP-dependent and AMP-independent mechanisms. The conditions under which these different mechanisms operate, and their biological implications are unclear. Here, we show that, depending on the degree of elevation of cellular AMP, distinct compartmentalized pools of AMPK are activated, phosphorylating different sets of targets. Low glucose activates AMPK exclusively through the AMP-independent, AXIN-based pathway in lysosomes to phosphorylate targets such as ACC1 and SREBP1c, exerting early anti-anabolic and pro-catabolic roles. Moderate increases in AMP expand this to activate cytosolic AMPK also in an AXIN-dependent manner. In contrast, high concentrations of AMP, arising from severe nutrient stress, activate all pools of AMPK independently of AXIN. Surprisingly, mitochondrion-localized AMPK is activated to phosphorylate ACC2 and mitochondrial fission factor (MFF) only during severe nutrient stress. Our findings reveal a spatiotemporal basis for hierarchical activation of different pools of AMPK during differing degrees of stress severity. | Yue Zong Chen-Song Zhang Mengqi Li Wen Wang Zhichao Wang Simon A.

| 9 | Comparative study of the transfection efficiency of commonly used viral vectors in rhesus monkey (Macaca mulatta) brains显示文摘Viral vector transfection systems are among the simplest of biological agents with the ability to transfer genes into the central nervous system.In brain research,a series of powerful and novel gene editing technologies are based on these systems.Although many viral vectors are used in rodents,their full application has been limited in non-human primates.To identify viral vectors that can stably and effectively express exogenous genes within nonhuman primates,eleven commonly used recombinant adeno-associated viral and lentiviral vectors,each carrying a gene to express green or red fluorescence,were injected into the parietal cortex of four rhesus monkeys.The expression of fluorescent cells was used to quantify transfection efficiency.Histological results revealed that recombinant adeno-associated viral vectors,especially the serotype 2/9 coupled with the cytomegalovirus,human synapsin I,or Ca2+/calmodulin-dependentproteinkinaseII promoters,and lentiviral vector coupled with the human ubiquitin C promoter,induced higher expression of fluorescent cells,representing high transfection efficiency.This is the first comparison of transfection efficiencies of different viral vectors carrying different promoters and serotypes in non-human primates(NHPs).These results can be used as an aid to select optimal vectors to transfer exogenous genes into the central nervous system of non-human primates. | Shi-Hao Wu Zhi-Xing Liao Joshua D.

| 11 | Predictability of sediment transport in the Yellow River using selected transport formulas显示文摘This paper evaluates the applicability of the sediment transport methods developed by Engelund and Hansen, Ackers and White, Yang et al., and van Rijn, together with the Wuhan methods developed in China, to the Yellow River, which has highly concentrated and fine-grained sediment. The sediment data includes over 1000 observations from the Yellow River, 32 sets of data from a canal, and 266 sets of data from laboratory flumes. The best predictions were obtained by the Yang 1996 method, the Wuhan method, and the modified Wuhan method by Wu and Long, while reasonably good predictions were also provided by the van Rijn 2004 method. The Engelund and Hansen, the Ackers and White, and the van Rijn 1984 methods in their original forms are not applicable to the Yellow River. The predicted results for total load concentrations were as good as for bed-material concentrations, even though the total load includes a large portion of wash load. | Baosheng WU D.

| 12 | OPTIMIZATION OF AUTOBODY PANEL STAMPING PROCESS BASED ON DYNAMIC EXPLICIT FINITE ELEMENT METHOD显示文摘Taking CPU time cost and analysis accuracy into account, dynamic explicit finite ele- ment method is adopted to optimize the forming process of autobody panels that often have large sizes and complex geometry. In this paper, for the sake of illustrating in detail how dynamic explicit finite element method is applied to the numerical simulation of the autobody panel forming process,an example of optimization of stamping process pain meters of an inner door panel is presented. Using dynamic explicit finite element code Ls-DYNA3D, the inner door panel has been optimized by adapting pa- rameters such as the initial blank geometry and position, blank-holder forces and the location of drawbeads, and satisfied results are obtained. | X.

| 13 | Superelasticity and Tunable Thermal Expansion across a Wide Temperature Range显示文摘Materials that undergo a reversible change of crystal structure through martensitic transformation(MT)possess unusual functionalities including shape memory, superelasticity, and low/negative thermal expansion. These properties have many advanced applications, such as actuators, sensors, and energy conversion, but are limited typically in a narrow temperature range of tens of Kelvin. Here we report that, by creating a nano-scale concentration modulation via phase separation, the MT can be rendered continuous by an in-situ elastic confinement mechanism. Through a model titanium alloy, we demonstrate that the elastically confined continuous MT has unprecedented properties, such as superelasticity from below 4.2 K to 500 K, fully tunable and stable thermal expansion, from positive, through zero, to negative, from below 4.2 K to 573 K, and high strength-to-modulus ratio across a wide temperature range.The elastic tuning on the MT, together with a significant extension of the crystal stability limit, provides new opportunities to explore advanced materials. | Y.L.

| 14 | A Model for Estimating Total Forest Coverage with Ground-Based Digital Photography显示文摘Vegetation fractional coverage (VFC) is one of the key indicators of vegetation distribution. In the work a measurement-based model was developed to derive total forest VFC (TG) as well as the VFC of trees (T) and shrub-grasses (G) separately in a subtropical forest area in Nanjing, China. Both upward and downward photographs were taken with a digital camera in 72 quadrats (10 m × 10 m each). Fifteen models were established and validated. Models jointly using both T and G performed better than those using the T and G separately. The best model, TG = T + G- 1.134 × T × G- 0.025 (R2 = 0.9115, P < 0.01, root mean squared error = 0.0789), is recommended for application. This model provides a good way to obtain total forest VFC values through taking tree and shrub-grass photos on ground below tree canopy rather than above tree canopy. | GU Zhu-Jun ZENG Zhi-Yuan SHI Xue-Zheng LI Lin D.

| 15 | Sol-gel derived HA/TiO_2 double coatings on Ti scaffolds for orthopaedic applications显示文摘Hydroxyapatite/titania (HA/TiO2) double layers were coated onto Ti scaffolds throughout for orthopaedic applications by sol-gel method. Differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and X-ray diffractometry (XRD) were used for the characterisation of the phase transformations of the dried gels and coated surface structures. Scanning electron microscope (SEM) equipped with energy dispersive spectrometry (EDS) was used for the observation and evaluation of the morphology and phases of the surface layers and for the assessment of the in vitro tests. The in vitro assessments were performed by soaking the HA/TiO2 double coated samples into the simulated body fluid (SBF) for various periods.

The HA la lyaeyre wr wasa ssu cbosaetqeude bnytl ya dipping-coated on the outer surface at the same speed and then heat-treated at difference temperatures. The results indicat that the HA phase begins to crystallize after a heat treatment at 560 ℃. The crystallinity increases obviously at 760 ℃. SEM observations find no delamination or crack at the interfaces of HA/TiO2 and TiO2/Ti. The HA/TiO2 coated Ti scaffolds displays excellent bone-like apatite forming ability when it is soaked into SBF.

| 16 | INFLUENCE OF COLD ROLLING REDUCTION ON MICROSTRUCTURE AND MECHANICAL PROPERTIES OF TWIP STEEL显示文摘The influence of cold rolling reduction on microstructure and mechanical properties of the TWIP (ttwinning induced plasticity) steel was investigated. The results indicated that the steel had better comprehensive mechanical properties when cold rolling reduction was about 65.0% and the annealing temperature was 1000℃. The tensile strength of the steel is about 640MPa and the yield strength is higher than 255MPa, while the elongation is above 82%. The microstructure is composed of austenitic matrix and annealing twins at room temperature, at the same time, a significant amount of annealing twins and stacking faults are observed by transmission electron microscopy (TEM). Mechanical twins play a dominant role during deformation, and result in excellent mechanical properties. | Z.L. Mi D. Tang Y.J. Dai H.Q. Wang S.S.

| 19 | Studies on the Catalytic Properties of Magnesia Supported on γ-Alumina显示文摘We have shown that MgO can be dispersed on γ Al 2O 3 with different loadings. The observed dispersion capacity of MgO on the surface of γ Al 2O 3 is higher than the theoretical monolayer dispersion value. The surface area and the maximum in the pore size distribution gradually decrease with the increase in MgO content at low loadings. The surface area and the maximum in the pore size distribution of MgO/ γ Al 2O 3 decrease more rapidly when the MgO content is large because the pores of γ Al 2O 3 become blocked. When small amounts of MgO are dispersed on the surface of γ Al 2O 3, the catalyst is very active and shows a good selectivity for the synthesis of glycol ethers. | JIAO Qing ze, ZHAO Yun, LI Xiao dan, EVANS D.
