1煤型稀有金属矿床:成因类型、赋存状态和利用评价显示文摘煤和含煤岩系中稀有金属元素的研究,是当今煤地质学研究的热点问题之一。煤和含煤岩系中高度富集并可以开发利用的稀有金属元素包括锂、钪、钛、钒、镓、锗、硒、锆、铌、铪、钽、铀、稀土元素(包括镧系元素和钇)、贵金属元素等。以煤-锗、煤-镓、煤-铀、煤-铌、煤-稀土元素等煤型稀有金属矿床为例,论述了这些矿床的地质成因、赋存状态和利用评价方法。煤型稀有金属矿床的研究,不仅对研究煤层的地质成因、煤层对比、含煤盆地形成与后期改造、区域地质历史演化和突发地质事件可以提供重要的煤地球化学和煤矿物学证据,而且对煤炭经济循环发展、煤炭利用过程中环境保护,以及对国家稀有金属资源安全也具有重要的现实和社会意义。代世峰 任徳贻 周义平 Vladimir VSeredin 李大华 张名泉 James C Hower Colin R Ward 王西勃 赵蕾 宋晓林 2014煤炭学报2014,39,8:111
2皮质下小血管病诊断的共识声明显示文摘血管性认知损害是用于描述一组涉及大血管和小血管的散发性和遗传性异质性疾病的诊断术语。皮质下小血管病可导致腔隙性梗死和进行性白质损害。被称为宾斯旺格病(Binswanger's disease, BD)的进行性白质损害患者构成了从单纯血管性疾病到合并神经变性病变的疾病谱。BD患者是一个相对同质性的亚组,存在缺氧缺血、腔隙性梗死和炎症,它们协同作用破坏血脑屏障和髓鞘。通过临床、脑脊液、神经心理学和影像学检查获得的多模式疾病标记物能促进该亚组患者的鉴别。本共识声明确定了一系列基于基础病理学改变的潜在生物学标记物,这将有助于诊断以及将来协作性治疗试验的患者选择。Gary A Rosenberg Anders Wallin Joanna M Wardlaw Hugh S Markus Joan Montaner Leslie Wolfson Costantino Iadecola Berislav V Zlokovic Anne Joutel Martin Dichgans Marco Duering Reinhold Schmidt Amos D Korczyn Lea T Grinberg Helena C Chui Vladimir Hachinski 王训师 张劼 陈涵丰 俞娅美 徐子奇 罗本燕 2016国际脑血管病杂志2016,24,6:18
3东方山羊豆脱水蛋白基因的克隆及初步分析显示文摘采用SMART RACE方法,从东方山羊豆盐诱导抑制性差减杂交cDNA文库中分离到了一个脱水蛋白(GoDHN)基因。该基因cDNA全长1 169bp,开放阅读框843bp,编码281个氨基酸,编码的蛋白质分子量为28.71kDa。经实时荧光定量PCR分析,GoDHN基因在东方山羊豆的茎和叶中表达量明显高于根中表达量,并且基因表达受ABA、NaCl和PEG的诱导,随着诱导时间的增加,表达量呈持续增长趋势。这些结果表明,DHN基因在东方山羊豆的抗逆性中可能起到重要的调控作用。本研究成功构建了pCAMBIA1302-DHN植物表达载体,为下一步转基因研究奠定了基础。李玉坤 王学敏 王赞 李俊 Vladimir C Nikolay D 孙桂枝 高洪文 2012草业学报2012,21,1:6
4Near-fault ground motions with prominent acceleration pulses:pulse characteristics and ductility demand显示文摘Major earthquakes of last 15 years (e.g., Northridge 1994, Kobe 1995 and Chi-Chi 1999) have shown that many near-fault ground motions possess prominent acceleration pulses. Some of the prominent ground acceleration pulses are related to large ground velocity pulses, others are caused by mechanisms that are totally different from those causing the velocity pulses or fling steps. Various efforts to model acceleration pulses have been reported in the literature. In this paper, research results from a recent study of acceleration pulse prominent ground motions and an analysis of structural damage induced by acceleration pulses are summarized. The main results of the study include: (1) temporal characteristics of acceleration pulses; (2) ductility demand spectrum of simple acceleration pulses with respect to equivalent classes of dynamic systems and pulse characteristic parameters; and (3) estimation of fundamental period change under the excitation of strong acceleration pulses. By using the acceleration pulse induced linear acceleration spectrum and the ductility demand spectrum, a simple procedure has been developed to estimate the ductility demand and the fundamental period change of a reinforced concrete (RC) structure under the impact of a strong acceleration pulse.Mai Tong Vladimir Rzhevskyt Dai Junwu George C Lee Qi Jincheng Qi Xiaozhai 2007Earthquake Engineering and Engineering Vibration2007,6,3:3
