In this study, the outstanding biocompatibility of silk fibroin (SF) and the highly efficient anti-bacterial effect of nano silver (NS) were utilized to prepare SF/NS composite film with anti- bacterial property. The structure and property of the film were characterized. The results showed that the structure of SF in the film was mainly silk I. SF in the film was almost insoluble in water. The tensile strength of film with NS was significantly lower than that of films without NS. When the addition of NS was within the range of 0%-0.6%, the elongation at break had no significant difference. The antibacterial rate of the film on staphylococcus aurens and escherichia coil increased with the amount of NS. The minimum amount of NS in the fdm was O. 1% and the maximum amount was 0.5%. 相似文献

XCP协议是一种针对高带宽时延乘积网络的Internet拥塞控制体系,其算法的关键是将拥塞控制参数嵌入每一主动数据包中,然后根据途经路由器的网络拥塞状况对相关参数进行修改,以达到预防拥塞的目的。本文分析了路由器参数对突发网络的性能影响,证明了路由器参数设置应该是优化效率与鲁棒性的折中,并提出了一种针对突发网络的自适应算法,实验表明新算法明显优于原算法。 相似文献

网络仿真器NS2无线模型的网络编码扩展 总被引:1,自引:0,他引:1
面向单播通信的无线网络编码机制COPE已经引起了越来越多研究者的关注。针对现有网络仿真平台不支持编码模式以及研究COPE机制所基于的试验平台环境难以广泛应用的问题,在网络仿真器NS2的无线模型中引入网络编码层并更改数据包传输流程,提出NS2的网络编码扩展的无线模型以支持对COPE机制的应用、改进以及新的无线单播网络编码机制的仿真研究。在该扩展模型上对COPE机制在ad-hoc网络中的性能进行仿真研究,仿真结果验证了该模型的可行性。 相似文献

The PSV·NS3, an expressing recombinant plasmid of dengue virus type 2 NS3 protein, was injected directly into the quadriceps
of Balb/C mice to explore whether it could inducing immune response. The splenic T cell subsets of two groups was analysed
by flow cytometry. It was found that the percentage of CD4+ and CD8+ T cells of experimental group were significantly higher than those of the control group. The titer of IgG antibody was as
high as 1∶5 120 in experimental group, but it couldn’t be detected in control group by ELISA. The western blot further proved
that the IgG antibody was specific for NS3 protein. Those results Suggested that inoculation Balb/C mice with PSV·NS3 could
inducing immune response, and the NS3 protein might be used as the candidate protein of DNA vaccine of dengue virus.

在单车道元胞自动机交通流N S模型基础上,通过引入不同的刹车概率来反映不同驾驶员的驾驶特性,并在周期边界条件下,对由激进驾驶车辆和谨慎驾驶车辆构成的混合交通流进行模拟.结果表明,在有谨慎驾驶车辆构成的交通流的临界密度以前,混合交通流的流量完全由谨慎驾驶员的特性决定;在谨慎驾驶车辆交通流临界密度以后,混合交通流的流量介于只有激进驾驶车辆和只有谨慎驾驶车辆的流量之间,小于完全是谨慎驾驶车辆流量和完全是激进驾驶车辆流量的线性之和;激进驾驶车辆和谨慎驾驶车辆的混合比例及它们的刹车概率对混合交通流的临界密度和流量有很大的影响. 相似文献
