Studies on the Electrochemical Behavior of Thiazolidine and Its Applications Using a Flow–Through Chronoamperometric Sensor Based on a Gold Electrode
Lai-Hao Wang,Wen-Jie Li
Molecules , 2011, DOI: 10.3390/molecules16097608
Abstract: The electrochemical behaviors of thiazolidine (tetrahydrothiazole) on gold and platinum electrodes were investigated in a Britton-Robinson buffer (pH 2.77–11.61), acetate buffer (pH 4.31), phosphate buffer solutions (pH 2.11 and 6.38) and methanol or acetonitrile containing various supporting electrolytes. Detection was based on a gold wire electrochemical signal obtained with a supporting electrolyte containing 20% methanol-1.0 mM of phosphate buffer (pH 6.87, potassium dihydrogen phosphate and dipotassium hydrogen phosphate) as the mobile phase. Comparison with results obtained with a commercial amperometric detector shows good agreement. Using the chronoamperometric sensor with the current at a constant potential, and measurements with suitable experimental parameters, a linear concentration from 0.05 to 16 mg L?1 was found. The limit of quantification (LOQ) of the method for thiazolidine was found to be 1 ng.

Abstract: This paper studies the load-balancing algorithm and quality of service (QoS) control mechanism in a 320Gb/s switch system, which incorporates four packet-level parallel switch planes. Eight priorities for both unicast and multicast traffic are implemented, and the highest priority with strict QoS guarantee is designed for real-time traffic. Through performance analysis under multi-priority burst traffic, we demonstrate that the load-balancing algorithm is efficient, and the switch system not only provides excellent performance to real-time traffic, but also efficiently allocates bandwidth among other traffic of lower priorities. As a result, this parallel switch system is more scalable towards next generation core routers with QoS guarantee, as well as ensures in-order delivery of IP packets.
1-{2-[(4-Hydroxy-3-methoxybenzylidene)amino]ethyl}-3-methylimidazolium hexafluorophosphate
Bin Li,Yi-Qun Li,Jie Liu,Wen-Jie Zheng
Acta Crystallographica Section E , 2009, DOI: 10.1107/s160053680901928x
Abstract: In the title Schiff base salt, C14H18N3O2+·PF6 , the dihedral angle between the planes of the aromatic and imidazole rings is 24.84 (8)°. The molecular structure exhibits an intramolecular O—H...O hydrogen bond, which generates an S(5) ring motif. In the crystal structure, the cations and anions are connected via O—H...N and O—H...F hydrogen bonds, resulting in a trifurcated interaction for the phenolic H atom.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809045115
Abstract: In the title Schiff base compound, C13H14Cl2N3+·PF6 , the dihedral angle between the aromatic ring and imidazole ring in the cation is 6.10 (2)°. Intermolecular C—H...F hydrogen-bonding interactions and π–π stacking interactions [centoid–centroid distance = 3.7203 (12) ] help stabilize the crystal packing.

Journal of Agricultural Science , 2011, DOI: 10.5539/jas.v3n1p140
Abstract: On the basis of defining the concept of coordinating urban and rural construction land use, this paper studied the coordination performance from two aspects, one was the dynamic balance index and the other was the coordination index. The results showed that: the coordination performance of the urban and rural construction land use was high in protecting cultivated land, and also was an important way to protect cultivated land; the coordination index of urban and rural construction land mainly located between 0.4 and 0.6, the internal structure of urban and rural construction land was unreasonable, the process of land urbanization lagged behind the process of population urbanization, which showed a downward trend and implied there was a large room for improving the performance.
Progress in vaccine development of hepatitis C virus infection


中国生物工程杂志 , 2006,
Abstract: Hepatitis C virus (HCV) accounts for the majority of cases of transfusion acquired hepatitis and may cause chronic hepatitis, cirrhosis and hepatocellular carcinoma. Currently, there is no vaccine against HCV and treatment is expensive and not always effective.The adaptive host immune response in viral clearance of HCV infection was described and the recent progress in vaccine development of HCV, focusing on the fields of DNA vaccine candidates, recombinant viral vectored vaccine candidates and combined (prime-boost) vaccine candidates were summarized. Some challenges and limitations of developing a HCV vaccine were also analysed. In summary, a promising approach of developing an experimental HCV vaccine to induce extremely potent and broad T-cell responses based on prime-boost strategy was presented.
Multiple Data Threshold Detecting Method Based on Autonomic Computing

LIU Wen-jie,LI Zhan-huai,

计算机科学 , 2011,
Abstract: Autonomic computing system often uses threshold to mark performance faults. Threshold is the boundary value of performance counter,which will be detected automatically by the system. When the performance counter of one of the devices reaches the threshold, it is considered that performance fault occurs on one of the devices. Then the autonomic manager will actively select policies to recover these faults,which therefore makes the whole system to maintain normal state. Nowadays,it lacks of research on system performance faults in autonomic computing field. On the basis of studying the self-monitoring of autonomic computing system, this paper proposed a multiple data threshold detecting method,by detecting the exceeding and recovering of the threshold in multiple times, system can effectively judge whether the performance fault occurs. This method assures the detecting accuracy,which provides the effective basis to recover fault for autonomic computing system.

Abstract: To lower the management cost of server clusters, a virtual mechanism on the basis of studying autonomic computing and the hardware features of patitionable servers was proposed. By virtualization of the hardware resources, physical resources could be mapped to logical resources, so that they could be unified to manage. Moreover, on the basis of unification of resources, a series of measures were proposed to configure resources of servers cluster to achieve the self-management of system.
