Foreign Direct Investment and its Effect on Self-Reliant Innovation in Jiangxi
Authors: Li Xiao Hong , Yu Yang Gang
Published: July 2011

In this paper, we attempt to inspect the status of Foreign Direct Investment (FDI) and its spillover effect on self-reliant innovation capability in Jiangxi province. Based on production function calculation, correlation coefficient between logarithm FDI and logarithm self-reliant innovation (sales revenue of new products) is -0.080. It indicates that the growth of FDI plays no or even negative effect on the growth of self-reliant innovation empirically. The reasons are mainly: (1) too many influence factors which affect the growth of self-reliant innovation disturb the model explanatory ability; (2) the influence of FDI is much less than of R&D labors and expenditures inputs. According to empirical research, the reasons for inefficiency FDI are mainly from two aspects: (1) FDI inward Jiangxi is mainly sourcing from undeveloped and developing countries (or regions) but not developed countries. (2) Technical spillover effect of FDI is performing under capacity for economic complexity and/or development threshold.

Authors: Cheng Guo Qiang , Song Yan Jin
Published: July 2011

Rock is a type of natural material containing microcracks. The evolution of mining-induced fracture field is one of the main problems of gas comprehensive control and rock mass seepage. The distribution of fissures and porosity in overlying strata under the mining influence were studied in this paper. The stratum subsidence was represented quantitatively using elastic thin plate theory and key strata theory. Based on the stratum subsidence, a program calculating porosity in overlying strata was developed based on VB. The results demonstrate that the porosity increase with face advances. The porosity becomes small with the decrease of strata depth, and the bigger separation is located in the strata below the key strata. The amount of the fissures in the middle part of overlying strata is more than that in two ends, and the porosity curves present symmetric arch shape in the initial stage. With face advances, the curves of porosity in the strata located the upper position change symmetric arch shape into saddle shape.

Authors: Ji Yu Bin , Gao Shi Yong , Ji Chen Feng , Zou Xiang
Published: July 2011

To explore how to calculate the effect of solanine on the Michaelis constant and the maximum reaction rate of NAT using the double reciprocal method. High performance liquid chromatography (HPLCP) was used, with 2-AF as substrate and its concentration as substrate concentration, and the rate at which 2-AF is acetylated into 2-AAF in intact HepG2 cells or in the cytoplasm of HepG2 cells as the reaction rate. The double reciprocal plot was made, with 1/S (reciprocal of the concentration of the substrate 2-AF) plotted against 1/V (reciprocal of the reaction rate), to yield a regression equation for calculating Km and Vmax. Studies on enzymetic kinetics have shown that, with intact HepG2 cells, the Km and Vmax for the negative control are 2.37×10-3±8.37×10-5 mM and 9.16×10-4±7.54×10-5nmol/106 cells, respectively, and that the Km and Vmax for the solanine group are 2.22×10-3±9.05×10-5mM and 5.14×10-4±3.72×10-5nmol/106 cells, respectively. For the cytoplasm of HepG2 cells, the Km and Vmax for the negative control are 8.95×10-3±2.61×10-4 mM and 2.55×10-6±1.92×10-8nmol/min·mg protein, respectively, and the Km and Vmax of the solanine group are 9.48×10-3±3.63×10-4mM and 2.43×10-6±1.32×10-8 nmol/min·mg protein, respectively. Statistical analysis showed that, for both intact HepG2 cells and cytoplasm of HepG2 cells, Km does not differ significantly between the negative control and the solanine groups, but Vmax does differ significantly for these groups (p<0.001 for the intact cells, p<0.05 for the cytoplasm). Solanine is a non-competitive inhibitor for the 2-AF substrate of NAT, and the double reciprocal method is a convenient and accurate method for calculating the constants of NAT kinetics.

Anodic aluminium oxide (AAO) templates were fabricated via a two-step anodization method. On the basis of getting the optimum preparation parameters of AAO templates, effects of two different pore-extending methods on morphology of AAO templates were studied. Field emission scanning electron microscope (SEM) was used to research surface morphology of AAO templates. The SEM images indicated that different pore-extending methods had a significant influence on morphology of AAO templates. The shape of nanopores of AAO templates was cylindrical after floating pore-extending method, but it was truncated cone-shaped with one dimensional gradient using immersed pore-extending method. Meanwhile, mechanism of different pore-extending methods on morphology of AAO templates was elucidated.

Authors: Feng Xue Dong , Ma Yan Fei
Published: July 2011

Volatilization of diesel oil in sand columns was conducted at the ambient temperature of 20 °C by spilling oil on the sand surface. The weight loss of oil was determined by pre and post weight of the sand columns and desiccant was measured on an electronic balance. The aim of this paper was to investigate the effect of moisture content on the volatilization of diesel oil in sand. The results show that the diesel oil and water in sand both volatilize at a linear rate with respect to time. The largest volatilization mass of diesel oil and water reach when the moisture contents are 8% and 20% respectively. Appropriate water content can help to pull the oil contaminants to the surface of the sand.

Thermodynamic Analysis of Oxide Nucleation in Steel Cooling Process
Authors: Li Zhi Qiang , Yu Jing Kun
Published: July 2011

Nucleating mechanism and controlling methods of Al2O3-TiO2 inclusion formed during steel cooling process is analyzed in this paper. According to the theory of nucleation, only TiO2 could satisfy the critical requirement of homogeneous nucleation to solidify stably when the temperature declines to less than 1863K. Furthermore, the generation of Al2O3 adhering on the surface of solid TiO2 is going to take place through heterogeneous nucleation, and then Al2O3 interacts with TiO2 to form Al2O3-TiO2 complex oxide. There would be no Al2O3-TiO2 complex oxide or much less Al2O3 on condition that the wTi·wO2 is less than 3.96×10-8. Both deeply deoxygenating treatments and controlling the mass of Ti-Fe alloy added into steel are effective means for improving steel quality.

Published: July 2011

To identify the pathogen of Mulberry wilt disease, a tested strain WJ-1 was isolated from a naturally infected mulberry in Guangzhou, Guangdong province, P. R. China. Hypersensitive reaction, along with Koch’s postulates, morphological, biochemical and physiological characterization, light microscope observation and molecular identification were performed on WJ-1. The results indicated that WJ-1 was a Gram-negative, short-rod shaped bacterium. Based on morphology and the 16S rRNA gene sequence analysis, WJ-1 strain was identified as members of the genus Enterobacter. The phylogenetic tree revealed that WJ-1 shared the highest homology with Enterobacter cloacae strain M5. It was another evidence on plant disease caused by Enterobacter species. We found that Enterobacter species could cause mulberry wilt disease in Guangzhou.
