    zCep85是哺乳动物中心体结合蛋白Cep85在斑马鱼中的同源蛋白,其靠近C端的部分具有一个coil-coiled功能域,这是大部分中心体结合蛋白共有的结构。目前对zCep85的研究尚浅,本实验室早期报道显示,哺乳动物细胞中hCep85特异性地拮抗hNek2,使得细胞停滞于G2/M期。但是,我们对其在脊椎动物胚胎发育中的功能依然所知甚少。为了深入探究zCep85在发育中的作用,本课题以斑马鱼(Daniorerio)为动物模型从基因结构、表达谱、功能分析等方面研究了zCep85在胚胎发育中的作用。此外,也研究了zNek2在早期胚胎发育中的功能。 首先通过整胚原位杂交实验对zCep85的表达谱进...zCep85 is homologous of mammal centrosome binding protein Cep85 in zebrafish, which has a coil - coiled functional domain near the C-terminal of protein.At present,the research on zCep85 is not much. hCep85 can specifically antagonise hNek2 ,which acts as the role in making the cell cycle arrested of G2 / M phase. In this project, zebrafish (Danio rerio) can be looked as an animal model of gene st...学位:理学硕士院系专业:生命科学学院_生物化学与分子生物学学号:2162013115262

    纳米技术与分析化学的交叉使其体现出新的生命力。基于纳米结构设计的纳米分子机器(nanomolecularmachine)和纳米器件(nano-device)也许将是下一代传感器,电子元件,分子自组装及信息处理装置的核心组成部件。利用聚合酶催化生成具有天然DNA形式的纳米结构是这一领域的一个热点,但是生物聚合的方法制备具有金属特性的M-DNA的研究工作尚未见报道。纳米晶的材料学特性与生物反应的高效性,特异的相结合是目前传感领域的重点发展方向,而目前这方面的研究多将生物分子偶联于纳米晶表面,这对设计及构建传感体系带来一定困难。基于对目前纳米结构研究的认识及纳米晶在分析化学领域的广泛应用,本论文从荧...The cross of nanotechnology and analytical chemistry refreshes the latter field. The nanostructure-based nanomolecular machines and nanodevices are considered as the potential core-hardwares in the next generation of sensors, electronic devices, self- assembled material and information output equipments. In present, a highlighted researching aspect is the construction of nanostructures with the na...学位:理学博士院系专业:化学化工学院化学系_分析化学学号:1912005140305

    A Study on Chinese Public Banks' Capital Binding

    Get PDF
    随着监管政策、金融对外开放等外部经营环境的改变,我国银行业资本约束环境逐步生成。公开上市是商业银行的发展趋势,本文选取5家上市银行作为研究对象。上市银行的资本充足率虽然相对较高,但也存在着较大的资本缺口。上市银行的资本约束表现为:首先,上市银行存在着较大的资本缺口,陷入了资本困境。中国银监会新的资本监管口径对资本扣除范围更广泛,在计算风险资产时取消了许多优惠系数,导致上市银行的资本充足率进一步大幅度下降。其次,上市银行资本补充受到多方面的限制,难以满足业务快速发展的要求。同时,上市银行的资本管理长期处于缺位的状态,无论是在认识上、在技术上还是在体制上都存在较大的差距,资本约束无法在银行内部实现...Abstract With the changes of external operation environment, such as reform of supervision policy and opening-up of financial services, China’s internal capital binding environment has gradually come into existence. Going public is the trend of commercial banks. This paper takes five public banks as its research subject. Although public banks have a relatively higher average of capital ade...学位:经济学硕士院系专业:经济学院财政金融系_金融学(含保险学)学号:20024203

    Discussion on the on-line automatic detection technology for the full-color LED module

    目前LED显示屏存在色差或者亮度差异源于单个模组在生产环节过程中控制不到位导致。本文提出了一种LED全彩屏模组的在线自动检测系统,包含显示屏自动定位控制,现场检测分析亮度均匀性,色度分布,质量判定分档等关键技术。该系统有助实现显示屏标准化检测,提高显示屏亮度一致性,提高生产效率及产量。The existence of the color or the brightness difference in the LED display panel is because of that the control of a single module is not in place occurring during the process of production. This paper presents an on-line and automatic detection system for the full color LED display module, including the automatic positioning control of the LED display, the detection and analysis of the brightness uniformity and the color distribution, and the quality evaluation and the quality grading among them. This system can realize the standardized detection of the LED display, improve its brightness uniformity, and increase the production effi ciency and the yield.福建省产学重大科技项目(编号:2013H6024

    Research on several issues of convertible bond financing

    论文以中国证券市场上可转债融资为研究对象,在梳理国外可转债融资理论假说的基础上,讨论我国可转债融资对标的股票价格的影响,并以之验证我国上市公司可转债发行的动机。上市公司将可转债融资视为一种延迟的股权性融资,这导致了可转债融资的股价效应与其它股权再融资方式存在很大的区别。论文通过以下几个层次对中国市场可转债融资的股价效应进行了详细的实证研究: 1、对沪深两市发布可转债融资信息导致的股价效应进行了研究,研究表明在宣告日当天及次日投资者异质信念明显增加且股价存在显著的负效应。不同市场环境下,宣告日的股价效应存在显著的差异。在熊市和调整市下,投资者异质信念的增加将减少股价的负效应。而在牛市时,投资者...The object of the study is the convertible bonds (CBs) financing in Chinese securities market. Based on the summary of the foreign hypothesis about CBs, we research the stock price effect caused by the issue of CBs and verify the motiveof the CBs issue in China.In practice, CBs is regarded as a kind of delay equity financing by listed companies, so the stock price effect by CBs are different with ...学位:博士后院系专业:管理学院会计系_会计学学号:200917004

    利用沪深两市A股上市公司2001~2007年的资料,研究了独立董事、审计委员会和股东制衡在年度财务会计报表披露过程中的有效性。实证研究结果表明,三者在报表披露过程中是有效的,独立董事规模和审计委员会的设立有助于降低财务会计报告被出示“非标“意见的可能性,并能促使报表更及时地披露,而股东制衡作用越大,财务会计报告被出示“非标“意见的可能性就越大,报表披露的及时性也越差。In this paper,the authors research the efficiency of independent director,audit committee and shareholder balance on statement disclosure.The empirical results indicate that the size of independent director and audit committee set up will significantly reduce the probability of qualified statement and promote the statement be disclosed in time.The empirical results also indicate that the stronger of shareholder balance,the more possible of statement be labeled qualified,and the later of the statement be disclosed

    Other Spaces in Legal Pedagogy

    Get PDF
    There is an increasing focus upon the material and metaphoric spatial dimensions of various academic disciplines, including law. This essay considers the spatial dimensions of legal pedagogy, focusing on Critical Race Theory (CRT). The essay first explains the critical program in law and how CRT grows out of it. The essay then suggests that the critical program, and especially CRT, is as much a human geographic or spatial construct as it is a social, political or historic one, and briefly describes the nature of human geography and legal geography. It next considers how metaphors for understanding CRT\u27s position in legal pedagogy are found in some of Foucault\u27s work on geography. In Des Espaces Autres ( Other Spaces ), Foucault argues that there are three distinct social spaces in society: real spaces, utopias, and heterotopias. What unites them, Foucault suggests, is a space that includes elements of all of these spaces, a space that he calls the mirror. Applying this frame, this essay posits that CRT, both the explicit courses on the topic and the discipline itself, should be re-mapped , that is, barriers to its inclusion in the broader legal pedagogy should be eliminated. In this way, CRT can function as a Foucauldian mirror rather than a heterotopia in legal pedagogy
