Ag纳米粒子(Ag NPs)具有广谱抑菌性和对哺乳动物细胞的低毒性,已得到广泛地认可和应用。目前Ag NPs的制备工艺繁琐,所用化学试剂易造成环境污染。本文以天然生物大分子柑橘果胶为还原剂和稳定剂,研究Ag NPs绿色制备工艺。用酸提醇析法提取橘皮果胶,得率24.2%,半乳糖醛酸含量73.5%,酯化度75.6%;以其为原材料,优化的柑橘果胶Ag NPs的制备工艺:用Na OH(20 g/L)溶解制备果胶溶液(50 m L,3 g/L),在温度70℃条件下滴入硝酸银(1 m L,0.5 mo/L)反应1 min。紫外-可见光谱分析该纳米粒子在410 nm处较强吸收。透射电子显微镜(TEM)观察结果表明:制备的Ag NPs平均粒径为5~15 nm,具有窄的粒度分布。扫描电镜(SEM)对制备的Ag NPs进行表征,表明该纳米粒子呈均匀球形。本研究提供了一种Ag NPs的绿色合成工艺,为抗菌材料的开发利用提供理论参考。

Nuclear factor Y （NF-Y） is a highly conserved transcription factor presented in all eukaryotic organisms, and is a heterotrimer consisting of three subunits： NF-YA, NF-YB, and NF-YC. In Arabidopsis, these three subunits are encoded by multigene families. The best-studied member of the NF-Y transcription factors is LEAFY COTYLEDON1 （LEC1）, a NF-YB family member, which plays a critical role in embryogenesis and seed maturation. However, the function of most NF-Y genes remains elusive. Here, we report the characterization of four genes in the NF-YA family. We found that a gain- of-function mutant of NF-YA1 showed defects in male gametogenesis and embryogenesis. Consistently, overexpression of NF-YA1, 5, 6, and 9 affects male gametogenesis, embryogenesis, seed morphology, and seed germination, with a stronger phenotype when overexpressing NF-YA1 and NF-YA9. Moreover, overexpression of these NF-YA genes also causes hypersensitivity to abscisic acid （ABA） during seed germination, retarded seedling growth, and late flowering at different degrees. Intriguingly, overexpression of NF-YA1, 5, 6, and 9 is sufficient to induce the formation of somatic embryos from the vegetative tissues. However, single or double mutants of these NF-YA genes do not have detectable phenotype. Collectively, these results provide evidence that NF-YA1, 5, 6, and 9 play redundant roles in male gameto- phyte development, embryogenesis, seed development, and post-germinative growth.

MEASUREMENT-BASED ADMISSION CONTROL USING MULTIPLE TIME-SCALES TEST

第40届中国控制会议

作者： Lin Zhen liang Shengkai Xie jinye Pan Jiazhen Institute of Technology Sanya University of Sanya

The traditional plant protection spray operation in China is mainly manual, and the spraying method of spraying liquid is widely used. The spraying method is serious, the utilization rate of pesticide is poor, the work efficiency is low, and the labor intensity of operators is large. The effect of ordinary spray on plants is not good. Electrostatic spraying technology improves the existing pesticide use, improves the efficiency of use and reduces environmental pollution. Electrostatic spray also has efficiency problems. It is found that spray parameters have great influence on droplet deposition. In this paper, the parameters combination of electrostatic spray precision spraying is studied. The principle and characteristics of electrostatic spray are *** deposition rate and charge to mass ratio of electrostatic spray under different voltage, water pressure parameters and the ratio of charge to mass are compared with experimental results. The experimental results show that when the spray pressure is 0.60 MPa, the best performance is for the 10 collocation and optimization of electrostatic spray in practical application.

A new measurement-based admission control algorithm to support Quality of Service(QoS) demand is proposed for soft real-time applications. In the algorithm, admission test is performed across Multiple Time-Scales (MTS) to accurately capture traffic fluctuation on various time-scales. By applying the QoS requirements directly to admission test, the MTS algorithm can properly meet the QoS target and maximize the bandwidth utilization.

为了解决传统优化算法在求解智能电网的实时电价模型过程中易陷入局部最优的不足,引入光学优化算法对实时电价模型进行求解。采用可变适应度的方法对光学优化算法求解模型过程中的不变适应度进行改进,提出自适应光学优化(Self-adaptive Optics Inspired Optimization,SAOIO)算法。根据迭代次数的变动,自适应地变动适应度从而提升收敛速度,提高求解精度。针对智能电网实时电价模型,对拉格朗日对偶算法和自适应光学优化算法进行同步仿真。结果表明自适应光学优化算法能够更好地寻得全局最优电价,提高结果精度,具有更好的实用性。
