The effects of different pH values on the reduction of nitrobenzene (NB or ArNO 2 ) by zero-valent iron (ZVI) were studied in groundwater through batch experiments. The concentrations of NB and its reduction product aniline were determined during the process of reaction. The changes in the reduction rates for nitrobenzene, the quantities of aniline formed, and the reaction kinetics during the reduction by ZVI were examined and analyzed at different pH values. Experimental results showed that nitrobenzene in groundwater could be reductively degraded effectively by ZVI. The optimum pH for the reduction was found to be 3.0 within the tested pH range of 3.0 to 12.0. The pH value tended to increase gradually with the progress of reduction reaction. At various pH values, the reduction of nitrobenzene by ZVI followed pseudo-first-order kinetics, and the observed kinetic constant k obs increased with decreasing pH. Both the reduction rate of nitrobenzene and the formation of aniline decreased with increasing pH. According to UV spectral and GC-MS analyses, aniline was the final reaction product of NB when reduced by zero-valent iron.

Digital subtraction angiography (DSA) is a type of medical imaging technique which can eliminate the interferential background and give prominence to blood vessels by computer processing. By analyzing the characters of DSA medical image sequence, we find angiograms are taken by the same instrument in same scene at different time, so the DSA serial images are present different parts of blood vessels. This paper proposes a novel method for this particular image fusion, which is using discrete wavelet transform improved by dynamic fuzzy data model. Firstly, we decompose each of DSA images of by 2-D discrete wavelet transform. Then we construct a membership function based on dynamic fuzzy data model to optimize the performance of wavelet coefficients selection in order to combine all series of DSA images in different level. At last, we use wavelet reconstruction to synthesize one DSA medical image which could contain more integrated accurate detail information of blood vessels. By contrast, the efficiency of our method is better than weighted average, Laplacian pyramid and traditional wavelet transform method. It is helpful to medical imaging aid diagnosis.

The dynamic membrane formation mechanisms and filtration mechanisms were investigated at 4 cm and 8 cm water head drop (WHD). Flux variation, resistance plot curve shape, the relationship t/V - t and t/V - V were investigated to study the dynamic membrane formation and filtration. And effluent turbidity and particles size distribution were also used to demonstrate the effluent particles size. Based on the flux stability, the dynamic membrane formation time is 120 min and 70 min for 4 cm and 8 cm WHD respectively. According to the forces analysis of a streaming particle, the reason was given about less time is needed for the dynamic membrane formation at higher WHD. Through the analysis of the resistance curve plot and the relationship of t/V - t and t/V - V, the dynamic membrane firstly is formed by cake growth, then small particles were captured by the formed cake, in this stage internal fouling is the dominant mechanism. After the dynamic membrane formation, screening becomes leading operation for particles removal including lager particles and small particles. Turbidity was used to illuminate the suspended solids in the effluent. Effluent turbidity shows that the membrane module occupies the good ability for particles removal before the dynamic membrane formation. Particles size distribution indicates that particles removal ability was formed gradually.

Wood is widely used as the materials for architecture, furniture and interor decoration. However, the conflagration is so serious that the fire retardant treatment has become urgent for wood materials. As more and more stress is laid on health and environment protection, fire retardant develops toward low toxicity and smoke suppression. In order to explore a low-toxic and highly-efficient fire retarding treatment technology, Eucalyptus.sp. and Choerospondias axillaris(Roxb.) wood were chosen as experiment materials, and a low-toxic fire-retardant solution consisting of dicyandiamide, phosphoric acid, boric acid, and triethanolamine was applied. The influence factors including concentration(A), temperature(B), pressure(C), soaking time(D) were investigated with orthogonal method, and TG and DSC evaluation were conducted. What's more, the oxygen index and smoke density were measured to seek for the best treatment technique. The results are as follows: (1) On the one hand, FRW itself contains no heavy metal, formaldehyde or any other toxic substance, therefore, it won't pollute the environment or hazard people's health when in use. On the other hand, barely smoke or toxic gas generate during the pyrolysis process of the wood treated with fire retardant. Therefore, FSW is a low-toxic fire retardant. In addition, it also has good fire retardant properties. (2) The best production condition for Eucalyptus sp. was A3B3ClD2,and the best production condition for Choerospondias axillaris (Roxb.) was A3B3C3D1.

We have recently developed a novel contrast-based ultrasonic particle imaging technique (Echo PIV) for multi-dimensional blood flow imaging. In the technique, the quality of vectors is important for quantitative blood flow imaging. Here we introduce an algorithm for vectors correction by filtering in frequency domain and applying continuity equation. The algorithm was tested in the Echo PIV imaging of rotational flow field and found to be effective in improving the quantitative blood flow imaging quality.

Nucleus is the largest and the most important organelle of eukaryotic cells. Data concerning lectin receptor distribution on nucleus of sexual cells in angiosperms are not available yet. Central cells of tobacco were isolated and fixed and the reactions of female cell nucleus to fluorescein isothiocyanate conjugated concanavalin agglutinin (FITC-Con A) and wheat germ agglutinin (WGA) were investigated by cooled CCD combined with CoolSNAP CCD. Result indicated that nucleus of central cells reacted positively to lectins. It was further found that Con A receptors mainly distributed on the nuclear envelope of the central cells. However, WGA receptors were concentrated on the two nucleoli of the central cells. Finally, relation of glycoprotein distribution with material importing into and exporting from nucleus through the nuclear pore complex was discussed. Possible role of lectin receptors on mediating karyogamy of female cell and male cell was discussed as well.

In order to explore the potential of Phyllostachys pubescens used as resources utilization on biomedcial, determination of the chemical components in five-year-old Phyllostachys pubescens was carried out by means of Py- GC/MS. 69 peaks were obtained from Phyllostachys pubesces and 62 compounds which occupy 99.99% of the total peaks areas were identified. The main components in Phyllostachys pubescens were pcetic acid (12.22%), pcetone(11.36%), propanoic acid, 3- amino-2-methyl-(7.57%), 2-propanone, 1-hydroxy- (6.07%), 2,3- butanedione (3.78%), propanoic acid, 2-oxo-, methyl-(3.68%), propanamide, N-acetyl-(3.04%), propanoyl chloride (2.78%), 3- hexanone(1.62%), 2-butenal, (E)- (1.52%), propanal(1.49%), 1,3- dioxol-2-one (1.44%), etc. Therefore, we can draw a conclusion that the pyrolysis byproducts of Phyllostachys Pubescens may be used as raw materials of biomedicine.

Polymyositis is an inflammatory myopathy characterized by muscle invasion of T-cells penetrating the basal lamina and displacing the plasma membrane of normal muscle fibers. In order to understand the different adhesive mechanisms at the T-cell surface, Schubert randomly selected 17 proteins expressed at the T-cell surface and studied them using MELK technique, among which 15 proteins are picked up for further study by us. Two types of functional similarity graphs are constructed for these proteins. The first type is MELK similarity graph, which is constructed based on their MELK data by using the Mutual Information similarity measuring method. The second type is GO similarity graph, which is constructed based on their GO annotation data by using the Maximal Depth method to measuring functional similarity. Then the subset surprisology theory is employed to measure the degree of similarity between two graphs. Our computing results show that these two types of graphs are high related. This conclusion added new values on MELK technique and expanded its applications greatly. Keywords—MELK; Polymyositis; GO; set surprise; mutual imformation

This representation has been mathematically proved to have degeneracy tends to zero, i.e., the length of a circuit tends to zero. Given any point considered in a DNA sequence, the number of A, T , G ,a ndC from the starting point could be calculated based upon an iterative comparison method. Furthermore, this paper gives a application to illustrate the efficiemcy of the method. Index Terms—DNA Sequence,Ggraphical Rrepresentations, Degeneracy

Using the structure deviation degree, a new function based on gradient error is put forward to evaluate the image quality of EIT. The method using the Sobel operator and gradient error information can effectively reflect the reconstruction quality of EIT image.
