A porcine reproductive and respiratory syndrome virus (PRRSV) was obtained from clinic samples. Genes 5 and 6 encoding for the viral glycoprotein 5 and a membrane protein of the PRRSV designated as HH08 were amplified by reverse transcription-PCR. These sequences were compared with reference sequences derived from different geographical locations. The results indicated that the virus belongs to the North American type rather than European. Comparative analyses of the genetic diversity between the PRRSV isolate HH08 and other Chinese as well as foreign reference strains of PRRSV were discussed based on the sequence comparison and the topology of phylogenetic trees constructed in this study.

The catalytic conversions of methanol, ethanol, dimethyl ether and diethyl ether to aromatic hydrocarbons (especially benzene, toluene and xylene) were achieved over 0.8%Zn/0.6%La/HZSM-5catalyst with a BTX selectivity as high as over 50% at reaction conditions of 710 K, WHSV 0.8 h1. The selectivity of BTX hydrocarbons in methanol aromatization reaction could remain 35% in 40 h. 2010 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.

Hydroxyapatite (HAP) modified with different metal salts were prepared by wet-impregnation method and used as a catalyst for the synthesis of glycerol carbonate via transesterification from glycerol and dimethyl carbonate (DMC). It was found that KF/HAP was a highly efficient heterogeneous catalyst for the synthesis of glycerol carbonate and the catalyst can be easily recovered and recycled. Under the conditions of molar ratio of DMC/glycerol of 2:1, the weight ratio of catalyst/glycerol of 3%, reaction time 50 min and reaction temperature 78 8C, the conversion of glycerol and the yield of glycerol carbonate reached 99.3% and 99.0%, respectively. The catalytic performance of KF/HAP is comparable to the homogenous catalyst of KF and better than that of K_2CO_3.

In order to solve the problems of low carrying capacity, low allowable speed and inconvenient storage and transportation of existing railway emergency repair beam, a technical scheme for deployable emergency repair beam was proposed. By using ANSYS software and the multi-body dynamics software UM (Universal Mechanism), the finite element model of the emergency repair beam and vehicle model of the C70 (C70 Open Wagon) freight train and the CRH380A (China Railway Highspeed 380A) high-speed train were established. The static analysis, modal analysis and vehicle-bridge interaction analysis of the emergency repair beam were carried out. The results show that: Compared with the existing emergency repair beam, the deployable emergency repair beam has the advantages of convenient storage and transportation, and rapid assembly. The developable emergency repair beam perfectly solves the contradiction between storage and assembly speed. With the increase of span and the decrease of the number of stable main trusses, the indicators of stress, mid-span displacement and acceleration of the key parts of the deployable emergency repair beam tend to be unfavourable. The combination of different main truss can realize the emergency repair beam with different span and width, and the mechanical properties of the emergency repair beam with different span and width are also different.
