Authors: Peng Hong Tao , Zhang Qi , Li Nai Sheng , Wang De Fa
Published: July 2011

The lime-stabilized soil was mixed with glutinous rice paste in proper proportion to determine the difference in compressive strength caused by introduction of glutinous rice paste. The experimental results show that the unconfined compressive strengths of lime-stabilized soil specimens treated with glutinous rice paste are all higher than those without treated at different curing times (7d, 28d, 40d, and 60d). The calculated fractal box dimension value of SEM image of lime stabilized soil sample is close to and slightly less than the one treated with glutinous rice paste. The SEM images show that the microstructure of lime-stabilized soil treated with glutinous rice paste is denser than that without treated. This kind of denser microstructure should be the basis of higher unconfined compressive strengths of the specimens treated with glutinous rice paste.

Published: July 2011

In order to investigate the effect of curing period and cement content of the specimen on fracture toughness of cement treated aggregate, a series of parametric tests have been conducted. By means of three-point bending method, the fracture toughness of cement treated aggregate was measured. In this study, four specimen curing periods (14 d, 28 d, 60 d and 90 d) and four different cement contents (4%, 5%, 6% and 7%) were used. The results indicate that the fracture toughness of cement treated aggregate is increasing with the increase of specimen curing period. Besides, with the increase of cement content, there is a tendency to decrease in the fracture toughness of cement treated aggregate. The higher cement content will be adverse to prevent the fine fissure inside cement treated aggregate base layer spreading further.

Authors: Wu Cheng Cheng , Peng Yong Zhen , Zhang Liang , Wang Shu Ying
Published: July 2011

A novel post-denitrification system fed by carbon source from primary sludge (PS) was used for enhancing biological nitrogen removal (BNR) of low C/N wastewater. This system included one anoxic/oxic (AO) reactor and a special reactor for simultaneous sludge fermentation and denitrification (Sifeden). Ammonia was nitrified to nitrate in AO and then the nitrate was reduced to dinitrogen in Sifeden , into which PS was added intermittently. Results showed that this system had high performance on nitrogen removal. Total nitrogen (TN) removal efficiency was higher than 85% and the effluent TN≤10mg/L in the condition of influent C/N≤2. In Sifeden, volatile fatty acid (VFA) produced from PS fermentation provided electron donor for nitrate reduction, and PS was preliminarily stabilized simultaneously. Oxidation-Reduction Potential (ORP) had a significant correlation with the denitrification performance. TN removal efficiency could be further improved if adopting proper PS addition strategy according to the ORP profiles.

Published: July 2011

Corrosion of aluminium anode in the seawater will reduce the life of the aluminum-air cell. It has been recognized that addition of inhibitor into the seawater electrolyte is an effective method that may prevent the corrosion of aluminium anode.The corrosion inhibition behavior of aluminium anode after addition of CeCl3 with different concentrations in simulated seawater has been investigated in this paper. EIS results showed that there was a significant increase of corrosion resistance when the concentration of CeCl3 reached 500mg·L-1 in simulated seawater, compared to the case without inhibitor. Potentiodynamic polarization curves showed that CeCl3 was a cathodic inhibitor in simulated seawater. SEM and XPS confirmed that the cerium oxide/hydroxide were formed at micro-cathodic areas of aluminum surface,which decreased the corrosion rate of aluminium anode.

Effects and Sensitivity of Soot-Induced Snow Albedo Change on Snowpack
Authors: Dang Su Zhen , Liu Chang Ming
Published: July 2011

The impact of soot-induced snow albedo on snow accumulation and snowpack ablation was evaluated using an energy and water balance land surface model with a newly modified snow albedo scheme. Model was tested against observed snow water equivalent (SWE) during the water year 2000 and 2002 at Ebbetts Pass site. Results show that when the soot mix ratio is 100 ng/g, the model performance is slightly improved during the snow ablation period, while snow albedo exhibits less variation. A basic sensitivity analysis indicates that snow albedo is sensitive to soot concentration in snow, and SWE is much more sensitive to soot mix ratio during the melting period, indicating the importance of accurately describing soot max ratio within snow for precisely predicting snow accumulation and snowpack ablation processes.

The data of mass loss rate and CO production rate is fitted, and the formula of its change with time is obtained. The computer monitor has slow pyrolysis speed on the 35 kW/m2, and the carbon layer on surface gradually thickened. So the heat will accumulate, and then the pyrolysis speed increases. The heat release rate reaches to the second peak. The fire growth index of monitor increases as the heat radiation intensity. But the fire growth index of paper has the opposition trend. The CO production rate of computer monitor is larger than paper’s. The experiment results can reflect the combustion characteristics of computer monitor on real fires.
Study on the Electron Excitation for Polychlorinated Dibenzo-P-Dioxins and Several Aromatic Substances by DFT Method
Authors: Su Yi Guo , Meng Yue , Ban Yue , Wang Xiao Jing
Published: July 2011

The electronic excitations and electron absorption spectra of polychlorinated dibenzo-p-dioxins (PCDDs) were investigated by the time-dependent density functional theory (/DFT). The main spectral features were interpreted on the basis of the electronic structure of PCDDs by fully considering the possible interference of coexist organic molecules for the electron spectra. With the numbers of benzene rings in aromatic molecules increasing, the excitation energies decrease. The excitation energies of the compounds with three or four benzene rings (phenanthrene or fluoranthene) fall into the electronic transition regions of PCDDs. Therefore these compounds were not possible differentiate from the electron spectra of PCDDs. Furthermore, with the amounts of benzene rings extending to surpass three and four, the energies decease continuously and run beyond of the transition energy ranges of PCDDs. Thus the electron excitation energies of those aromatic molecules with three or four benzene rings were in the range of PCDDs, acting as the possible interferential substances for the detecting of PCDDs.

Authors: Lu Hong , Guan Huai Jin , Chen Hui , Lu Lu
Published: July 2011

Previous studies have revealed that the mutation of Rpe65plays a critical role in inherited retinal dystrophies. However, little is known about the genetic regulatory network for Rpe65 and inherited retinal dystrophies. We combined gene expression microarray analysis and quantitative trait loci (QTL) mapping to characterize the genetic regulatory network for Rpe65 expression in the eye of BXD recombinant inbred (RI) mice. Our analysis found that the expression level of Rpe65exhibited much variation in the eye across the BXD RI strains and between the parental strains, C57BL/6J and DBA/2J. Expression QTL (eQTL) mapping showed that one microarray probe set of Rpe65 has highly significant linkage (Likelihood Ratio Statistic) scores. Moreover, the QTL was mapped to within 3 Mb of the location of the gene itself (Rpe65) as a cis-acting QTL. Through mapping the joint modulation of Rpe65, we identified Ches1/Foxn3 as downstream gene of Rpe65. Then the gene co-regulatory network analysis was constructed. The genetic genomics approach demonstrates the importance and the potential power of the eQTL studies in identifying genetic regulatory networks that contribute to inherited retinal dystrophies.

Research on Autogenous Volume Deformation’s Influence on Thermal Creep Stress of Concrete High Arch Dam
Authors: Xie Ling Fei , Yang Li
Published: July 2011

Autogenous volume deformation is an important parameter of anti-cracking behaviors of concrete. The sensitivity analysis of influence of concrete autogenous volume deformation on thermal stress of Xiaowan high arch dam is carried out based on simulation of temperature field. When presuming autogenous volume deformation, expansion concrete and shrinkage concrete are considered. The results show that early expansion and early shrinkage concretes have obvious influence on arch dam’s early thermal st ress; however have less influence on dam center’s maximum thermal stress. The longer of expansion period, the smaller of dam center’s maximum thermal stress; and the final residual thermal stress, which can benefit the concrete’s anti-cracking quality.

The Aggregated Signature for Many-to-One Communication Based on Rabin Signature
Authors: Han Yi Liang
Published: July 2011

To improve the efficiency of many-to-one communication, the aggregated signature Rabin signature is proposed. When the several senders sign and send the message to a receiver, they could do the same operation as the common Rabin signature. The several signature texts are aggregated and produced a signal signature text. Instead of verifying the several signature for several times, the verifier only verifies the aggregated signature for one time to determine the validation of the all of the messages. The discussion shows that, by this way the data amount and the computational cost could be reduced nearly 1/2 of the common algorithm. The proposed algorithm has the same secure level as the common Rabin signature.
