A series of orthogonal array experiments were conducted using carbon source, ammonia nitrogen and total phosphorus （TP） as major influencing factors to investigate the effects of nutrients on biofouling formation and preponderant bacteria diversity in the recirculatiug cooling water system. Carbon source was demonstrated to be the most significant determinant affecting the biofouling formation. A minimum biofouling outcome was obtained when BOD2, NHa＋-N and TP were 25, 10, and 1 mg/L, respectively. Then the preponderant bacteria strains in biofouling mass under two typical culture conditions （negative and favorable） were identified applying both traditional biochemical methods and further molecular biology technology with phylogenetic affiliation analysis, which indicated that Enterobacteriaceae Enterobacter, Micrococcaceae Staphylococcus, Bacillaceae Bacillus, Enterobacteriaceae Proteus, Neisseriaceae Neisseria and Pseudomonadaceae Pseudomonas were dominant under negative condition, while Enterobacteriaceae Klebsiella, Enterobacteriaceae Enterobacter and Microbacterium - under favorable one.

It is very difficult to capture the target in the microgravity environment, simply by relying on ground operators. Based on shared control theory, this paper effectively combines the decision-making ability of ground operators and the independent ability of space robot, through making full use of independent control ability of the space robot, and reducing operators’ workload and working time, to achieve more valid capture for targets. Shared control is more accurate capture of the target compared with teleoperation in experimental.

本文用数字粒子成像测速仪 (DPIV) ,对圆柱体在静水中作正弦振动而产生的振荡流场进行了实测研究。通过相位锁定技术和互相关分析法 ,分别获得了圆柱体在振动周期中 8个不同相位的流场速度矢量及涡量强度等值线分布。实测表明 ,当 KC =12 时 ,圆柱振荡尾流中将存在一个有明显周期性且较规则的斜向涡街 ,涡街主要由一股较强的二次流及其两侧的非对称的涡对构成 ,涡街与圆柱体振动方向成± 45°夹角。而当KC =6.2 8时 ,由于吸附于柱体的涡对未能脱离柱体进入其尾流 ,因而无涡街产生。文中还分析和讨论了斜向涡街产生的机理并对振荡流中柱体受力情况进行了量测。受力测量结果表明 :当斜向涡街稳定时 ,圆柱体各向受力差异不大 ;但在涡街方向转变期间。

Due to the complexity of geological background and the adverseness of natural geographical environment in the Qinghai-Tibet Plateau,it is very difficult to carry out petroleum geological study in this region. The Qinghai-Tibet Plateau is the only blank space of petroleum exploration on a large scale. The authors carried out the surface geochemical exploration of oil and gas in the Gangbatong-Ya'anxiang and Dongqiao-Nam Co of the Qinghai-Tibet region. Based on the data of actual detection and experiments in the studied area,the characteristics of concentration and profile distribution of the main geochemical exploration indicators(total adsorbed hydrocarbon,altered carbonate,thermal released mercury,etc.) were discussed. The origin of hydrocarbon was also discussed. Moreover,the oil and gas potential of different sections in the Qiangtang Basin and the Biru Basin were evaluated,which could provide references for the exploration and prediction of oil and gas in this region. The concentrations of total adsorbed hydrocarbons in the Ya'anxiang of Suoxian County-Zadong of Baqing County and the Jiecha-Dangxiong of Anduo County in the Qinghai-Tibet region are high,averaging 312.64 μL·kg-1 and 164.36 μL·kg-1. Their altered carbonate concentrations are relatively low,averaging 0.11% and 0.56%. Their concentrations of thermal released mercury are relatively high,averaging 13.09×10-9 and 1.94×10-9. Geochemical exploration results in fact reflect hydrocarbon information in the underground,which are mainly petroleum associated gas and over-matured cracking gas. The Jiecha-Charenluma and the Xiamaya'ertong-Suoba sections in the Qiangtang Basin are the most favorable ones for oil and gas and the Ekou-Zadong section is relatively favorable one,while the Nam Co and the Zigetangcuo-Dongqiao sections in the Biru Basin are the favorable ones for oil and gas,and the Jiang Co-Nading Co and the Ya'anxiang-Ya'ertong sections are relatively favorable ones.

Ribozyme probe based on molecular beacon (MBR) for monitoring enzymatic cleavage process in real time is designed and studied. The approach relies on ri-bozyme substrates modified at the two arms, with a fluores-cent moiety attached to the end of one arm and a non-fluorescent quenching moiety attached to the end of the other arm. MBR is employed to directly convert the cleavage information into fluorescence signal in real time. Compared with traditional approach, this method provides a no-radiolabeling, sensitive and effective way to research on the ribozyme activity, enzymatic dynamic process and ri-bozyme function during gene therapy. The activity of the ribozyme against hepatitis C virus RNA (HCV-RNA) is stud-ied based on this assay.

Onychin inhibits proliferation of vascular smooth muscle cells by regulating cell cycle

Progressive Edge-Growth （PEG） algorithm is a novel approach for construction of low-density parity-check （LDPC） codes with large girth. However, PEG algorithm ignores the effect of the number of shortest cycles. In this paper, we propose a modified PEG algorithm with Polynomial of Cycle, which achieves not only large girth, but also minimizes the number of shortest cycles significantly. Simulation results show that our proposed algorithm can improves the performance of LDPC codes.

p-Aminophenol （PAP）, a typical amphoteric compound, has been widely used as raw chemical material and important intermediate in various fields. To study on the recovery of PAP, an experimental comparison of the adsorption and desorption properties of PAP onto three types of hyper-cross-linked resins in aqueous solutions was performed. This paper focuses on the static equilibrium adsorption and desorption behaviors, the adsorption thermodynamics, the column dynamic adsorption and desorption, and other influencing factors of adsorption, such as temperature and pH values. All the isothermal data fit well to the Freundlich model. The capacity of equilibrium adsorption for PAP on NG-10 is the highest within the temperature range 288K318K,which may greatly contribute to the advantage in specific surface area, especially the micropore area, of the adsorbent. While in the desorption experiments, NG-9 achieved relative well regeneration efficiency whether by ethanol or by 4% hydrochloric acid. Furthermore, the results of column tests and field applications were also proved that NG-9 was an effective sorbent for the reclamation PAP from wastewater.
