磁性琼酯糖亲和吸附剂的合成与应用

采用反相悬浮包埋技术合成了粒径在43-295μm之间的磁性琼脂糖微球。磁性琼脂糖微球经环氧氯丙烷活化后，分别键合6-氨基已酸、氨基乙酸和乙二胺为间隔臂，用水溶性碳二亚胺为缩合剂，分别偶联对氨基苯甲脒、l-精氨酸甲酯和胍基已酸，制备了3种磁性亲和吸附剂，并用于尿激酶粗品的分离纯化。测定了活性回收率和比活提高倍数，并与以磁性葡聚糖为基质的磁性亲和吸附剂对尿激酶的纯化效果进行了对比。

一种消除锯齿的图像放大算法

为了最大程度消除图像放大后出现的锯齿现象,提出了一种新的二次导数连续的多结点立方卷积插值函数,通过增加结点使得插值曲线更加的平滑;同时对插值函数引入逆梯度约束条件,然后根据图像放大的倍数定义一个适当的模板对图像进行卷积操作,自适应的消除图像放大后出现的锯齿现象。实验结果表明,该算法在对图像执行高倍放大时,几乎看不到锯齿,同时图像的清晰度也保持的较好。     

烧结熔剂的活性度和显微结构研究

通过活性度实验和显微结构分析对国丰钢铁有限公司常用的3种烧结熔剂(生石灰、白云石和石灰石)进行基础性能研究。结果表明,3种熔剂的活性度均不是很好,生石灰熔剂的活性度实测值显著低于其理论值,石灰石熔剂的活性度高于白云石熔剂的活性度;白云石和石灰石熔剂的最佳煅烧温度都在1300℃左右;3种熔剂的杂质含量较多,且分布不均匀,降低了熔剂的有效含量和活性度。     

知识产权效率价值的理论渊源

法的效率价值反映了制度建构的效率维度，同时，也是制度运行经济合理性的体现。基于知识产权制度区别于其他部门法的特殊性，其效率价值的经济学内涵更多源于对知识产权客体价值属性的认识，即“知识价值论”。近现代的思想家们对于知识财产的不同价值观赋予了知识产权制度效率价值特殊的内涵。在此基础上，以现代制度经济学和法经济学分析框架为基础，以促进和实现效率最大化为目的，构建了现代知识产权制度的效率价值理论。并运用这一基本理论，以帕累托效率为标准对现行知识产权制度中的效率价值进行验证。     

从《题记》看《边城》主题及沈从文的创作观

目前对《边城》主旨的探讨，论者很少从《题记》的角度进入，谈及沈从文的创作观，特别是生命观时，论者或多或少的存在着一些缺陷。文章从两个方面展开：其一是从题记和文本内容探讨作品的主旨：爱和死亡；其二是阐述沈从文的创作观，主要围绕创作观的核心问题：为何要创作的问题。沈从文的创作是为了生命。生命以三种形态展开：健康的生命，自由的生命，审美的生命。     

On Pseudo-Holomorphic Curves from Two-Spheres into a Complex Grassmannian G（2, 5）

Let s ： S2 → G（2, 5） be a linearly full totally unramified pseudo-holomorphic curve with constant Gaussian curvature K in a complex Grassmann manifold G（2, 5）. It is prove that K is either 1 4 1 or 4/5 if s is non-±holomorphic. Furthermore, K = 1/3 if and only if s is totally real. We also prove that the Gaussian curvature K is either 1 or -4/3 if s is a non-degenerate holomorphic curve under some conditions.     

Numerical method for the inverse heat transfer problem in composite materials with Stefan-Boltzmann conditions

In this paper, one specific kind of heat transfer problem with nonlinear Stefan-Boltzmann conditions are considered in a three dimensional multi-layer domain. Theoretical results for forward and inverse problems are presented. Numerical simulations of specific models from applications are provided to demonstrate the heat transfer process in the composite materials of forward problem. One reconstruction method is proposed to find the corrosion part, and the numerical examples show that the reconstruction algorithm is effective.     

Non‐coordinating‐Anion‐Directed Reversal of Activation Site: Selective C−H Bond Activation of N‐Aryl Rings

An Rh‐catalyzed selective C?H bond activation of diaryl‐substituted anilides is described. In an attempt to achieve C?H activation of C‐aryl rings, we unexpectedly obtained an N‐aryl ring product under non‐coordinating anion conditions, whereas the C‐aryl ring product was obtained in the absence of a non‐coordinating anion. This methodology has proved to be an excellent means of tuning and adjusting selective C?H bond activation of C‐aryl and N‐aryl rings. The approach has been rationalized by mechanistic studies and theoretical calculations. In addition, it has been found and verified that the catalytic activity of the rhodium catalyst is obviously improved by non‐coordinating anions, which provides an efficient strategy for obtaining a highly chemoselective catalyst. Mechanistic experiments also unequivocally ruled out the possibility of a so‐called “silver effect” in this transformation involving silver.     

Non-Markovianity for a qubit system driven by a classical phase noisy laser

The nonlinear interaction between electron-acoustic shock waves in a dissipative, non-Maxwellian plasma composed of cold fluid electrons, stationary background ions, and inertialess superthermal electrons has been studied. The effects of plasma parameters on the trajectory changes (i.e., phase shifts) of shock waves after their head-on collision is our main concern. The results indicate that the interactions between shocks are different from those of solitons. Also, it is found that the occurrence and variation of trajectory shifts may be due to the combined role played by the dispersion and dissipation of the colliding nonlinear structure.
