Design and Implementation of Educational Administration System Based on .NET

高校教务管理系统是实现教育管理信息化的重要因素，是高等教育管理的重要组成部分。它能够完成日趋繁杂的教务工作，提高信息流通速度，便于师生之间的沟通与交流。Internet的迅速发展为人们获取各种信息和服务提供一个新的途径，基于互联网的高校教务管理信息系统已经成为当今重要的一种管理信息模式，它在提高工作效率，迅速提供各类教务信息等方面有着重要的现实意义。 针对教务管理用户较集中、处理数据量大的情况，本文采用B/S和C/S模型互补的方式，设计一个基于.NET的教务管理系统。对于业务逻辑十分复杂而且数据量很大的模块尽量采用C/S结构，而对于查询和小数据量业务的模块则采用B/S结构，这样可以减少客户端...College educational administration management system is an important factor of realizing education management information, it’s also an important part of the higher school education management. It can complete multifarious academic work, increase the information flow speed, and it is convenient for the communication between teachers and students. The rapid development of Internet provides a new wa...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X200923014

合同解除标的理论之反思与重构

传统理论认为合同解除的标的是有效成立的合同,与合同解除权以及其他合同救济手段的存在根据相矛盾,从而致使合同解除制度陷入逻辑困境。合同解除的标的应当重构为基础性合同权利义务关系,将救济性合同权利义务关系排除在外。同时,该解除针对的并非合同关系本身,乃是合同关系之效力

Expression of the Soluble Human Fas Ligand in Dictyostelium discoideum

［中文文摘］用PCR扩增从激活的人中性粒细胞中得到的编码可溶性Fas配体胞外区中第14 1个到第2 81个氨基酸的cDNA ,将其与hCG_β信号肽片段融合到质粒MB12neo中,随后导入到盘基网柄菌AX3细胞中,得到分泌性表达hFasL的重组菌AX3_H3。为提高shFasL的表达量,对质粒pMB12neo作了改造,得到衍生质粒pMB74。利用质粒pMB74克隆表达shFasL ,得到高通量表达shFasL的重组菌AX3_pLu8。在复杂培养基HL_5C中,重组菌的细胞密度可达(1 5～2 )×10 7 mL ,AX3_H3及AX3_pLu8分泌的shFasL浓度分别为2 3 5 μg L及2 0 6 μg L。利用合成培养基SIH培养重组菌AX3_H3及AX3_pLu8,细胞密度均达到(4～5 )×10 7 mL ,shFasL浓度则分别达到111μg L和4 2 0 μg L。［英文文摘］An expression system is described for high-yield production of recombinant soluble human FasL (shFasL) in Dictyostelium discoideum cells. DNA encoding amino acids 141～281 of hFasL was PCR amplified from cDNA derived from activated human neutrophils. The resulting product was fused with a DNA fragment encoding hCG-β signal peptide and cloned in the expression vector pMB12neo. Dictyostelium strain AX3 was transfected with this plasmid, yielding a recombinant strain called AX3-pCESFL95-H3. In order to mprove the shFasL expression level , pMB12neo was optimized by replacing its transcriptional terminatorPpolyadenylation segment of the 2H3 gene with an actin8 terminatorPpolyadenylation segment , yielding derived expression vector pMB741 The recombinant Dictyostelium strain called AX3-pLu8 was generated with this new plasmid. When the recombinant cells were cultivated in a complex HL-5C medium, a cell density of (115～2) ×107PmL was reached , and the shFasL level expressed by strains AX3-pCESFL95-H3 and AX3-pLu8 was 2315 μgPL and 206μgPL , respectively. By using a newly developed synthetic medium called SIH as culture medium, higher cell density of (4～5) ×107PmL was achieved. Correspondently, 111 μgPL and 420 μgPL shFasL were secreted by recombinant strains AX3-pCESFL95-H3 and AX3-pLu8 ,respectively.国家自然科学基金资助项目(No.20306025,30370039
