1波激振动的理论预报及与实船试验结果的比较(英文)显示文摘本文研究一艘大型海船的波激振动问题。该船在运行过程中发生了频繁的波激振动,导致严重的结构裂纹。文中对四种预报船体波激振动响应的理论及其计算机程序进行了描述。这些理论在计算水动力载荷和结构振动时具有各自的特点,如:线性、二阶、非线性、频域、时域、二维和三维等。相应的程序(WASIM,SOST,SINO和VERES)对低频波浪诱导响应预报已有较多的验证。文中对各程序在波激振动预报中的前提条件作了说明。计算中进行了参数敏感性分析并给出了主要结果。在与实船试验结果的比较过程中选择了十个不同的工况,对其海况、航向和试验现象给出了简要描述。对低频波浪诱导和高频波激振动响应分别进行了比较,得出了一些有意义的结论。顾学康 GauteStorhaug Jelena Vidic-Perunovic Gabriel Holtsmark Jens Block Helmers 2003船舶力学2003,7,6:5
2区域供热:丹麦能源供应之基石显示文摘数十年来丹麦国家政府和地方政府都不遗余力地推行区域供热政策,现代的区域供热已经成为该国供热体系之基石,同时丹麦也是在联合发电方面最有成就的欧洲国家.丹麦发展区域供热有其历史与地理上的原因,直接触发因素是1973/74和1979/80年间的能源危机,那时丹麦93%的能源供应依赖石油进口.Peter Helmer Steen 刘旖祺 2005区域供热2005,,4:4
3Intravenous immune globulin suppresses angiogenesis in mice and humans显示文摘Human intravenous immune globulin(IVIg),a purified IgG fraction composed of~60%IgG1 and obtained from the pooled plasma of thousands of donors,is clinically used for a wide range of diseases.The biological actions of IVIg are incompletely understood and have been attributed both to the polyclonal antibodies therein and also to their IgG(IgG)Fc regions.Recently,we demonstrated that multiple therapeutic human IgG1 antibodies suppress angiogenesis in a target-independent manner via FcγRI,a high-affinity receptor for IgG1.Here we show that IVIg possesses similar anti-angiogenic activity and inhibited blood vessel growth in five different mouse models of prevalent human diseases,namely,neovascular age-related macular degeneration,corneal neovascularization,colorectal cancer,fibrosarcoma and peripheral arterial ischemic disease.Angioinhibition was mediated by the Fc region of IVIg,required FcγRI and had similar potency in transgenic mice expressing human FcγRs.Finally,IVIg therapy administered to humans for the treatment of inflammatory or autoimmune diseases reduced kidney and muscle blood vessel densities.These data place IVIg,an agent approved by the US Food and Drug Administration,as a novel angioinhibitory drug in doses that are currently administered in the clinical setting.In addition,they raise the possibility of an unintended effect of IVIg on blood vessels.Reo Yasuma Valeria Cicatiello Takeshi Mizutani Laura Tudisco Younghee Kim Valeria Tarallo Sasha Bogdanovich Yoshio Hirano Nagaraj Kerur Shengjian Li Tetsuhiro Yasuma Benjamin J Fowler Charles B Wright Ivana Apicella Adelaide Greco Arturo Brunetti Balamurali K Ambati Sevim Barbasso Helmers Ingrid E Lundberg Ondrej Viklicky Jeanette HW Leusen J Sjef Verbeek Bradley D Gelfand Ana Bastos-Carvalho Sandro De Falco Jayakrishna Ambati 2016Signal Transduction and Targeted Therapy2016,1,1:3

5载脂蛋白E及脂肪酸与脑卒中、冠状动脉粥样硬化性心脏病、死亡风险的关系显示文摘膳食脂肪对心血管健康和死亡率的作用仍然存在争议。由于载脂蛋白E(apolipoprotein E,APOE)是脂质运输和代谢的核心,研究者通过检测APOE—ε4基因型,评估了血浆脂肪酸与脑卒中、冠状动脉粥样硬化性心脏病(冠心病)、死亡风险之间的关系。刘青 叶鹏 Satizabal CL Samieri C Davis-Plourde KL Voetsch B Aparicio HJ Pase MP Romero JR Helmer C Vasan RS Kase CS Debette S Beiser AS Seshadr Sudhai 2018中华高血压杂志2018,26,11:2
