Study on Evidence Application of Expert Opinion in Civil Litigation
随着科学技术的进步及案件难度的提升,司法鉴定在民事诉讼中起着越来越重要的作用,其正确运用有助于查清案件事实,使法官正确适用法律,根据尽可能接近的损失作出公正合理的判决,从而定纷止争,回应人民群众对司法的新要求、新期待。在法律意识逐步提升的同时,鉴定结果的称谓也在不断地更新和完善。2012年民事诉讼法出台后,鉴定意见的说法被广泛运用。法律还以明文规定的形式确立了鉴定意见的证据属性,强调其作为一种证据必须经过法庭的质证、认证方可发挥其证据效用。此外,法律还规定了鉴定人出庭制度及专家辅助人制度。通过鉴定人或专家辅助人出庭作证,保障诉讼当事人平等的诉讼权利和地位,也为法官采信鉴定意见提供依据和参考。尽...As science and technology advances and case difficulty augments, judicial identification plays an increasingly important role in civil litigation.

Design and Implementation of Clinical Pathway Information System Based on Caché
临床路径是医院重要工作的一部分。国家卫生行政部门已经于2009年正式 提出该项工作,主要是完成某一单病种的诊断、治疗、康复和护理所制定的一个 诊疗标准化模式。临床路径实施初期阶段,医院使用手工方法进行管理,无法固 定单个病种治疗过程,且经常调整治疗方案,根本无法达到卫生行政部门的要求, 与实行临床路径的初衷相违背。为了规范临床路径管理工作,构建一套临床路径 信息管理系统显得尤为迫切和重要。 本文讨论了临床路径信息系统的概念与背景,分析了临床路径的业务流程, 并简述了该系统与其它业务系统的关联。需求分析完成后,又完成了该系统的架 构、功能要求及Caché数据库的设计工作。根据需求...Clinical pathway is an important part of the hospital daily routine. The State Health Department has formally proposed this work in 2009,with focus on establishment of a standardized model on clinical diagnosis, treatment, rehabilitation and care.

TNF induced RIP3-dependent NADH depletion
肿瘤坏死因子(tumornecrosisfactor,TNF)能诱导L929细胞产生相互作用蛋白3(receptor-interactingprotein3,RIP3)依赖的程序性细胞坏死,并且在该过程中,胞内的线粒体产生的活性氧(reactiveoxygenspecies,ROS)会积聚,同时当RIP3的表达水平敲低时,胞内ROS的积聚也受到了抑制。但是RIP3如何影响ROS的具体机制仍不清楚。 因为ROS的产生主要在线粒体电子传递链上,而还原型辅酶Ⅰ(NADH)和还原型辅酶Ⅱ(NADPH)又是电子传递链的底物,RIP3是否能通过改变电子传递链上NADH或者NADPH的消耗来影响ROS。我...TNF (Tumor necrosis factor) can induce necrosis in L929 cells which is RIP3 dependent. ROS (reactive oxygen species) production increase during this process which is also RIP3 dependent, RIP3 expression knockdown inhibits the accumulation of ROS. But the mechanism of how RIP3 affect the ROS production is unknown. ROS is generated mostly through the ETC (electron transport chain) of mitochondria, ...学位:理学硕士院系专业:生命科学学院_细胞生物学学号:2162012115244
近25 a 银川市城市化进程中热力景观格局演变分析
Abstract: Based on the Landsat images and statistical data,in this paper the urbanization process and thermal landscape dynamics of Yinchuan City were analyzed. The objectives of this study were as follows: ① To analyze the spatial and dynamic characteristics of urban thermal landscapes based on the landscape pattern index; ② To assess the influence of the urbanization process on the thermal landscapes; ③ To understand the relationship between the land use pattern and the land surface temperature ( LST) based on the distribution index. The results showed that there was a significant heat-island effect in Yinchuan City,and the high temperature area was consistent with the built-up area and the unused land. LST declined from the downtown to the suburbs,and an obvious difference of the dynamic characters of the thermal landscapes could be identified at the different stages of urbanization. LST for various land use had obvious discrepancies,the mean LST for the land use types was in a descending order of unused land,construction land,green land and water body. Different land use types had different thermal distribution at different stages of urbanization. The land use pattern influenced the urban thermal environment,especially the spatial distribution of green land and unused land affected LST more significantly
厌氧条件在不同Fe( II) 浓度测定方法中必要性的比较研究
厌氧是目前Fe(II)测定方法中常选择的处理方式,但是不可避免会给实验操作带来不便。为了方便、准确地测定铁还原体系中的Fe(II)浓度,对比研究了厌氧条件对草酸—草酸铵和盐酸两种典型浸提方法测定Fe(II)浓度的影响。结果表明:对于草酸—草酸铵浸提法,厌氧条件是必须的,以防止提取液中的Fe(II)被氧化,而且样品浸提1 h 便可用于Fe(II)的测定;然而对于盐酸浸提法,厌氧条件却并不是必须的,对Fe(II)浓度测定基本不产生影响。因此,为简化实验操作或在没有厌氧条件的情况,可利用盐酸浸提法测定铁还原体系中Fe(II)浓度
An Analysis of the Time View of Don Delillo's Novels from the Perspective of Narratology - A Case Study of The Body Artist and Point Omega
个体的时间感关系到个体的生存状态。在后现代社会中,个体的时间观受到社会经济、科技文化、消费社会以及大众传媒的影响,呈现出时间感淡化、碎片化、瞬间化等特征。德里罗的《人体艺术家》和《欧米伽点》通过讲述居于社会边缘的艺术家在社会边缘空间的生活状态,表达对时间观的一种警惕与反思。 本文以德里罗的《人体艺术家》和《欧米伽点》为研究对象,从叙述者、情节、叙事空间三个角度解析《人体艺术家》和《欧米伽点》的叙事特征,以叙述学的角度分析的两部小说对时间的呈现。 绪论部分首先简述了唐·德里罗的小说创作之路,随后分析并概况了唐·德里罗在美国与国内的研究状况,最后阐明本文的选题思路以及研究方法。 论文的第一章...The individual's sense of time is related to the individual's living condition. In postmodern society, the individual's view of time is influenced by social economy, science and technology culture, consumer society and mass media, showing the characteristics of time desalination, fragmentation and instantaneousization. Don Delillo’s The Body Artist and Point Omega express a sense of vigilance and ...学位:文学硕士院系专业:人文学院_比较文学与世界文学学号:1022014115238
Design, synthesis and biological activity evaluation of three types of kinase inhibitors with nitrogen-containing skeletons
蛋白激酶是人类生命活动中重要的信号传递使者,小分子蛋白激酶抑制剂是以蛋白激酶信号通路功能为基础,结合蛋白激酶结构进行设计合成的小分子药物。自2001年,第一个激酶抑制剂类药物Imatinib获得FDA批准,成为本领域发展的里程碑后,小分子激酶抑制剂发展迅速,大量的小分子激酶抑制剂类化合物进入临床使用。在众多蛋白激酶中,RET融合基因被鉴定为NSCLC(非小细胞性肺癌)亚型中的新致癌基因,即RET重排的存在与肺腺癌亚型相关,所以开发针对RET激酶的抑制剂有望用于相关非小细胞肺癌的治疗。 本论文以三类含氮双环母核为基础,以KQF-04-013-01为先导化合物(leadcompound),辅助以...Protein kinase is an important signaling messenger in human life. Small molecule protein kinase inhibitor can be designed on the basis of protein kinase structure. In 2001, Imatinib was the first kinase inhibitor, approved by FDA, serving as a milestone in the field of targeted cancer theraphy. Until now, 32 small molecule kinase inhibitors have been approved by FDA and achieved great success in c...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:2162014115257
