聚乙二醇活化酯修饰重组人白细胞介素-2

目的研究单甲氧聚乙二醇三聚氯氰(Methoxypolyethylene Glycol activated with cyanuric chloride,CC-mPEG)和单甲氧聚乙二醇硝基苯基碳酸盐(Methoxypolyethylene Glycol p-nitrophenyl carbonate,NC-mPEG)两种PEG活化酯修饰重组人白细胞介素-2(rhIL-2)的修饰条件和修饰后的性质。方法在不同反应条件下用CTLL-2细胞/MTT法测定rhIL-2修饰后的生物学活性。结果随着PEG活化酯的摩尔比提高,修饰率增加,用CC-mPEG修饰rhIL-2后生物学活性损失很大,PEG400的加入可以降低CC-mPEG的投料摩尔比;NC-mPEG修饰的rhIL-2后生物学活性基本保留。     

@MIT research centre at Delft University of Technology： A bridge between research, education, society and profession

In 2006, we launched the @MIT Research Centre （Modification, Intervention Transformation） at the Faculty of Architecture at Delft University of Technology. @MIT was founded to respond to the need for an integrated, multi-disciplinary approach to the transformation of the built environment. @MIT aims to bring momentum to the renewal of education and research, and sees improved relations between the scientific and the professional community as a key step in this process. The @MIT research programme stands at the epicentre of the current debate on continuity and change in architecture and construction. The conservation and transformation of existing objects is becoming more and more of a necessity, with social, economic and cultural implications. @MIT builds the bridge successfully between the profession, the society, education and research.     

论国家赔偿法的修改亮点与缺憾

国家赔偿法经过修改完善,基本解决了原国家赔偿法存在的赔偿门槛高、标准低、范围窄、程序乱等诸多问题。其修改亮点主要表现在以下几个方面：国家赔偿归责原则多元化,拓宽了国家赔偿的范围;完善了国家赔偿程序,畅通了赔偿渠道;明确举证责任规则,完善了赔偿制度;提高了赔偿标准,明确精神损害赔偿;规定赔偿金由财政部门统一支付,保障了赔偿费用的到位。不足之处在于赔偿范围有待进一步扩大,未将受害人的间接损失纳入赔偿范围;没有规定行政不作为造成损害的赔偿责任;没有规定公有公共设施致害的赔偿责任;未建立与国家赔偿制度相衔接的国家补偿制度。     

《文心雕龙·附会》修改说

《文心雕龙》中《附会》篇旨,不应作为构思文章、谋篇布局的写作命题来理解。它实质上是作家在完成作品革创之后,重新审理文稿,而依照作文章法对文稿修改整理、加工完善的定稿活动内容.即现代意义上的修改再创造。只有作这样的理论认识,才能解释《附会》在全书篇次结构中的现存位置,得出《文心雕龙》的确体系完整、结构严密的评价。读解《附会》原文.也可以证明其实践针对性不在写作进行时态,而在成文之后的完善文辞的努力,其目的是“令章靡疚,亦善之亚”.义承《指瑕》篇结论。     

阴离子对γ—Al2O3外表面的化学修饰

用硅酸乙酯溶液和氟化铵溶液浸渍的方法对γ－Ａｌ２Ｏ３外表面进行化学修饰,用比表面积测量仪和四氯化碳吸附法测量了比表面积及比孔容,用常压微反色谱连用装置评价了催化剂在甲醇脱水反应中的催化性能。结果表明,不同焙烧温度、不同浸渍条件对γ－Ａｌ２Ｏ３的表面结构及催化性能具有一定的影响。     

Shape modification of Bézier curves by constrained optimization

The Bézier curve is one of the most commonly used parametric curves in CAGD and Computer Graphics and has many portant problem, and is also an important research issue in CAD/CAM and NC technology fields. This work investigates the curves to satisfy the given constraints and modify the shape of the curves optimally. Practical examples are also given.     

Seismic force modification factor for ductile structures

INTRODUCTION In codes for seismic design of buildings of many developed countries, elastic response spectra are adopted to calculate the base shear forces. For exam-ple, the base shear defined in Japan code 1997 is: FEK=DsFesC0ZAiRtW (1) where Rt is the elastic design spectrum; Ds is the structural coefficient changing among 0.25 to 0.50 to take account of different ductility of different struc-tures; W is the total weight of a structure; the others are site coefficient, irregular…     

Preparation of a novel biodegradable β-cyclodextrin-containing polymer

A novel cyclodextrin-containing polymer was prepared by graftingβ-cyclodextrin onto the backbone of poly(D,L-lactic acid)(PLA).First,mono(6-(2-aminoethyl)amino-6-deoxy)-β-cyclodextrin(β-CD-6-en)was prepared by sulfonylation and amination ofβ-cyclodextrin and modified poly(D,L-lactic acid)(MPLA)was prepared by free radical polymerization of maleic anhydride and PLA.Then,grafting ofβ-cyclodextrin derivative to MPLA backbone was carried out by N-acylation reaction of MPLA andβ-CD-6-en in dimethyl formamide.The...     

体育教师开发校本课程的动力研究——基于行为改造型激励理论

体育校本课程的开发在新课程改革中具有重要地位,自从《课标》实施以后,校本课程的开发一直不是特别理想。尝试利用行为改造型激励理论去深度剖析影响一线体育教师开发的动力问题,并依据该理论提出改变体育教师消极行为的方法,推动新课标的顺利实施。
