Theoretical Study on the Organic Functionalization of the Silicon Surfaces

Abstract Chemical modification of semiconductor surface is of great interest because of its potential applications. A marriage of organics and semiconductors is expected to result in new device applications, including molecular electronics, sensors, nanotechnology and so on. Due to the limited resolution of experimental techniques, however, it is becoming apparent that the interplay between ex...学位：理学硕士院系专业：化学化工学院化学系_物理化学(含化学物理)学号：20032511

Design and Preparation of Pd-UiO MOFs Catalyst and Performance for Catalytic Tandem Hydrogenation and Esterification of Carbon Dioxide to Ethyl Formate

随着现代工业的蓬勃发展，全球二氧化碳（CO2）排放量已经达到每年数百亿吨。CO2作为主要的温室气体，其大量排放导致的全球气候变暖正得到全世界的普遍关注。同时，CO2也是一种无毒、不可燃、地球上蕴藏量最为丰富且廉价易得的C1资源。将CO2转化为有价值的燃料或化学品不仅可以减少CO2的排放减缓温室效应，而且还可以变废为宝，因此得到许多科学家的重视，是现代科学研究的热点之一。 在众多的CO2转化产物中，甲酸乙酯（HCOOEt）作为一种重要化工品，在食品、医药、香料、有机合成中有着广泛应用。根据已经报道的文献研究，由CO2加氢合成HCOOEt需要经过两步反应。第一步：CO2加氢生成甲酸中间体，其中金...Global carbon dioxide (CO2) emissions have reached several ten billions of tons per year with the development of industry. CO2 as a main greenhouse gas is being widespread concern around the world. However, CO2 is also a non-toxic, non-flammable, abundant, and available C1 resources.So, the conversion of carbon dioxide into the valuable chemicals is one of the hot pots in modern scientific researc...学位：理学硕士院系专业：化学化工学院_物理化学学号：2052014115158

A reliability study of students' rating on teachers' teaching on the basis of the generalization theory

通过计算概化系数和可靠性指数来评价医科院校教师教学水平学生评价量表的信度。结果发现:教学内容、教学方法、教学态度、教学效果领域信度较好,教学组织领域信度尚可,若要修改,可考虑增加教学组织的条目数,减少其他领域的条目数。Objective: This study uses the generalization theory to check the reliability of students' rating on teachers' teaching on the basis of the generalization theory. While the findings indicate good reliability in the areas of teaching content,method,attitude and outcome,the reliability of teaching arrangement indicates changes need to be made probably by increasing questions in this survey item.昆明医科大学教研教改项目(2013JY-Y39

中国内陸農村の出稼ぎと所得分布 : 1999年四川省農家調査の個票データを用いて

In this paper, we analyze econometrically the effect of migration on income differences in rural China, by a case study using the micro data of Sichuan rural household survey in 1999, conducted by Research Center for Rural Economy (RCRE). We compare the distributions of the predictive income if migrants have been working in agriculture and the actual one, reveal that migrant\u27s earnings contribute to the improvement of income, and that most of migrants are produced from the low-income class

基于角膜地形图的泪膜视频预处理

在基于角膜地形图的泪膜稳定性评估中,针对眼动、睫毛反射和背景干扰,本文提出了一种泪膜视频的预处理算法。首先,利用索贝尔算子(Sobel operator)进行模糊图像检测,然后对灰度图像进行形态学开运算以获取环状图样凸显的目标图像,再通过霍夫圆检测以及快速傅里叶变换提取目标图像的环状图样频率,依据环状图样频率对目标图像进行带通滤波。最后,二值化及形态学闭运算用于确定环状图样区域。本文从数据库中随机选取10段泪膜视频,应用上述算法逐帧进行泪膜图像处理。实验结果表明,该算法有效地去除了视频序列中的无效图像,并实现了环状图样的定位,为后续泪膜稳定性的评估奠定了基础

Characterization of single chain antibody against DR5

目的探究抗人死亡受体5(dr5)单链抗体(Adr5SCfV)的特异性。方法 ElISA检测Adr5SCfV的效价、亲和力和表位分析。WESTErn blOTTIng检测单链抗体的特异性。MTT检测Adr5SCfV对结肠癌细胞SW480的生长抑制。结果 ElISA显示抗人死亡受体5单链抗体抗体效价为1.2x104。通过间接ElISA证实Adr5SCfV与Adr5MAb识别dr5胞外段(Edr5,系本实验室自己构建)的同一个位点。Adr5SCfV的亲和力常数为2.12x10-2。Edr5与Adr5SCfV能够特异结合。MTT检测结果显示,Adr5SCfV抑制SW480细胞生长呈剂量依赖性,Adr5SCfV终质量浓度分别为0.225 Mg/Ml、0.45 Mg/Ml、0.9 Mg/Ml、1.2 Mg/Ml。200μl时,SW480细胞的存活率分别为97.7%,70.9%、70.1%、23.6%。结论 Adr5SCfV能与Edr5特异性结合,并有较强的活性。The aim of our study is to characterize the property of aDR5ScFv.We employed ELISA to determine the titer,relative affinity and epitope recognition of aDR5ScFv,while Western blotting to analyze the specificity of aDR5ScFv.We also measured the inhibitory effects of aDR5ScFv on colon cancer cell SW480 growth by MTT.We found that the titer of aDR5ScFv was 1.2×104;aDR5ScFv and aDR5mAb recognized the same epitope on DR5 molecule;and the affinity constant of aDR5ScFv was 2.12×10-2.Furthermore,aDR5ScFv could recognize eDR5 specifically and inhibit the growth of SW480 cells in a dose-dependent manner(aDR5ScFv final concentrations of 0.225,0.45,0.9,1.2 mg/ml correspond to SW480 viabilities of 97.7%,70.9%,70.1%,23.6%).Western blotting showed the binding of aDR5ScFv to DR5 was specific.Thus,we concluded that binding of aDR5ScFv to DR5 is specific and aDR5ScFv had strong activity.福建省自然科学基金(C0710046
