Published: July 2014

Long-term application of fertilizers greatly increased soil denitrification. DGGE profiles revealed that fertilization significantly changed the community composition of denitrifying bacteria (DNB) mainly due to the differences in nitrogen availability, except for RM treatment. Phylogenetic analysis showed that all DNB sequences were most similar to some genus from theRhizobiaceaefamily of α-Proteobacteriaclass. These results suggest that long-term fertilization have different effects on the activities and community composition of dynamics at different level.

Authors: Yang Yan Chun , Dang Jian Wu , Wang Yang Ping
Published: July 2014

In order to further improve the quality of medical image fusion,an improved medical image fusion method, based on nonsubsampled contourlet transform (NSCT),is proposed in the paper. A fusion rule based on the improved pulse coupled neural network (PCNN) is adopted in low frequency sub-band coefficient. Because human visual is more sensitive to all local region pixels instead of single pixel,it is more reasonable that the region information stimulates PCNN instead of single pixel. Each neuron of PCNN model is stimulated by the region spatial frequency of low frequency sub-band coefficient .Low frequency sub-band coefficient is determined by the times of firing. When choosing the bandpass directional sub-band coefficients, the directional characteristics of NSCT has been made best use of in the paper.A fusion rule based on sum-modified Laplacian is presented in bandpass directional sub-band cosfficients.The experiment results show that the proposed method can greatly improve the quality of fusion image compared with traditional fusion methods.

Published: July 2014

Nonlinear insulated materials can uniform electric field distribution in non-uniform electric field. In order to inhibit the electric tree initiation and propagation inside high-voltage cross-linked polyethylene (XLPE) insulated cable, a kind of 220kV high-voltage XLPE insulated cable with new structure is designed by embedding nonlinear shielding layer into XLPE insulation layer of high-voltage cable with traditional structure in this study. Experimental and simulation results indicate that the nonlinear shielding layer can effectively inhibit electrical tree propagation inside the XLPE specimens, and obviously extend the breakdown time caused by electric tree propagation. When the electrical tree propagates into the nonlinear shielding layer sandwiched between insulation layers of cable, the electric field distribution near the tip of electrical tree is obviously improved. These findings prove the feasibility and the effectivity of inhibiting electrical tree propagation inside high-voltage cable by adding nonlinear shielding layer into the insulation layer.

Use Horizontal Aeration Method to Treat Organic Pollution in Soil
Authors: Xu Lu Yang
Published: July 2014

This design adopts the method of horizontal arrangement to set the aerator pipes because it’s more effective than an upright way. The pipes are divided into two vertical levels. Firstly there should be an excavation of foundation pit or grooves to put the pipes in two levels. Then the pipes in two levels can be set at vertical directions. After burying the pipe the earth should be backfilled into the grooves. When backfilling the lower level groove, we put some certain microorganism to help cleaning the organic pollution. While working, the pipes above are mainly used to manufacturing gas phase concentration difference, letting the organic volatilize and goes into the atmosphere. The pipes in lower level are mainly used to provide oxygen to microorganisms in the soil, so that they can decompose organic and make them into inorganic which is no harm to the soil and ground water.
