针对双侧靠泊平面布置形式的离岸式油码头的靠船墩设计，通过有限元计算软件建立分析模型，对3个不同设计方案的靠船墩结构受力进行分析，得到每个方案的桩顶轴力、弯矩和墩台位移等计算结果，并对其进行对比。结果表明：船舶撞击力为... 详细信息

针对双侧靠泊平面布置形式的离岸式油码头的靠船墩设计，通过有限元计算软件建立分析模型，对3个不同设计方案的靠船墩结构受力进行分析，得到每个方案的桩顶轴力、弯矩和墩台位移等计算结果，并对其进行对比。结果表明：船舶撞击力为靠船墩设计的控制性荷载，双侧泊位的船舶撞击力一般不同时发生且作用方向相反，共用靠船墩的设计方案能部分分担甚至抵消一侧船舶撞击力，从而显著改善结构受力，减小桩基内力和墩台位移，并节约建设成本。

在软土地基上通过回填砂形成的港口后方陆域,其场地为在密实砂层下卧软弱土层的特殊场地。利用一维场地地震反应分析软件DEEPSOIL的时域非线性分析方法建立分析模型,选择10组地震加速度记录作为输入地震动,分析该类特殊场地的地震反应。结果表明,软弱土层在强震作用下会产生大的剪切变形,使滞回阻尼充分发挥从而耗散地震能量;地震在通过软弱土层向上传递过程中迅速减小,软弱土层具有明显的减震和隔震效果。

A micro-scale rod-like heterostructure derived from molybdenum-based metal organic framework(Mo-MOF)has been successfully prepared via subsequent annealing treatment,which assembled from N-doped carbon encapsulated MoSe_(2) nanosheets grown on the surface of MoO_(2) microrod(named as MoO_(2)@MoSe_(2)@NC).For this novel heterostructure,the MoO_(2) nanoparticles assembled into rod core not only serve as supporting substrate for facilitating the fast kinetics of Li+cations inside the electrode but also protect the MoSe_(2) structure from restacking in the charge/discharge ***,the outer-layered MoSe2 nanosheets enable the fast lithium ion movement owing to its large interlayer ***,this unique rod-like core-shell structure composite could further effectively alleviate the structural strains caused by large volume expansion during charge/discharge process,thus leading to stable electrochemical performance when evaluated as anode material for lithium ion *** testing exhibits that the MoO_(2)@MoSe_(2)@NC heterostructure presents highly reversible capacity of 468 mAh g^(-1)at 0.5 A g^(-1)and superior rate capability(318 mAh g^(-1)even at 5.0 A g^(-1)),which is attributed to the synergistic effect of N-doped carbon encapsulated MoSe2 nanosheets and MoO_(2) nanoparticles.

湖南省是白颈长尾雉(Syrmaticus ellioti)的主要栖息地之一,分析其潜在适生区对该物种保护具有现实指导意义。本研究综合考虑地形、水源、气候、植被、土地类型以及人为干扰等多项因子,结合有效的白颈长尾雉分布点,利用最大熵(maximum entropy, Maxent)模型预测湖南省白颈长尾雉的适宜栖息地。结果显示, Maxent模型10次重复运行训练集的平均曲线下面积(area under the curve, AUC)值为0.964,预测结果优秀;到县道距离(dis_x)、最暖季度降水量(bio18)、到混交林距离(dis_mxf)和平均气温日较差(bio2)是影响白颈长尾雉适宜栖息地分布的主要因子,到稀树草原距离(dis_sav)、海拔(altitude)和到荒地距离(dis_bar)对其分布的影响也较大,其余因子具有一定影响但并不显著;白颈长尾雉适生区面积为4.76×10^(4)km^(2),主要位于湘西、湘南的山地,但适宜栖息地破碎化程度较高,整体较为分散。

Cellular & Molecular Immunology 2007年第2期4卷 147-151页

作者： Wei Xiao Xueling Chen Lin Zhou shengjun lu Zhihui Liang Xiongwen Wu Department of Immunology Tongji Medical College Huazhong University of Science ＆ Technology Wuhan 430030 China Department of Immunology School of Medicine Shihezi University Shihezi 832002 China

Peptide-MHC class I complex （pMHC） is a specific ligand for TCR recognition, and important for CD8^＋T cell activation. Here we described a genetically engineered divalent class I major histocompatibility complex （MHC） molecule, H-2K^d/IgG2aFc, a fusion protein consisting of the extracellular domains of H-2K^d, a murine MHC class I molecule, and the Fc region of IgG2a. This fusion protein is expected to attach the H-2K^d molecule to the surface of murine macrophage （MФ） through its Fc portion binding to Fc receptor （FcR） of MФ. cDNAs coding for the extracellular domains of H-2K^d and the Fc region of IgG2a were cloned respectively, and then recombined into plasmid pcDNA3.1（＋）. The H-2K^d/IgG2aFc protein was expressed by the plasmid-transfected cell line J558L, and purified from its supernatant with a Staphylococcal Protein A （SPA） column. The fusion protein showed a 58.4 kDa band as revealed by SDS-PAGE and Western blotting with murine IgG-specific antibody, which consists with that expected for extracellular domains of H-2K^d heavy chain plus the Fc region of IgG2a. The sandwich ELISA assay with antibodies specific for Fc portion and for H-2K^d indicated the fusion protein consists of both Fc portion and H-2K^d. Peritoneal MФ of C57BL/6 （H-2K^b） can be stained with H-2K^d specific monoclonal antibody （mAb） after incubated with the H-2K^d/IgG2aFc fusion protein. These results demonstrate the fusion protein can be used to attach the H-2K^d molecule to the surface of murine MФ, and provides a novel means to manipulate the T cell recognized epitope on the surface of murine MФ, which can be applied to activate antigen-specific cytotoxic T lymphocyte （CTL）.
