成人高等教育质量监控体系研究论纲

加强成人高等教育质量监控研究,有利于实现成人高等教育教学的目标管理、精细化管理,也有利于实现成人高等教育的制度化、规范化和科学化.目前学界对成人高等教育质量监控的研究,虽然取得了不少研究成果,但还存在许多不足之处,需要进一步探讨成人高等教育质量的价值取向,全面把握当前成人高等教育质量监控工作的基本现状,从教学信息、教学督导、教学管理等方面系统构建起成人高等教育质量监控体系.     

The modernity of Dedekind’s anticipations contained in What are numbers and what are they good for?

Archive for History of Exact Sciences - We show that Dedekind, in his proof of the principle of definition by mathematical recursion, used implicitly both the concept of an inductive cone from an...     

The expansion of GPCR transactivation-dependent signalling to include serine/threonine kinase receptors represents a new cell signalling frontier

G protein-coupled receptor (GPCR) signalling is mediated through transactivation-independent signalling pathways or the transactivation of protein tyrosine kinase receptors and the recently reported activation of the serine/threonine kinase receptors, most notably the transforming growth factor-β receptor family. Since the original observation of GPCR transactivation of protein tyrosine kinase receptors, there has been considerable work on the mechanism of transactivation and several pathways are prominent. These pathways include the “triple membrane bypass” pathway and the generation of reactive oxygen species. The recent recognition of GPCR transactivation of serine/threonine kinase receptors enormously broadens the GPCR signalling paradigm. It may be predicted that the transactivation of serine/threonine kinase receptors would have mechanistic similarities with transactivation of tyrosine kinase pathways; however, initial studies suggest that these two transactivation pathways are mechanistically distinct. Important questions are the relative importance of tyrosine and serine/threonine transactivation pathways, the contribution of transactivation to overall GPCR signalling, mechanisms of transactivation and the range of cell types in which this phenomenon occurs. The ultimate significance of transactivation-dependent signalling remains to be defined but it appears to be prominent and if so will represent a new cell signalling frontier.

ZD15振动机除铁原理

去除粉状耐火材料、玻璃原料、电瓷物料中的铁磁物质，目前工业上普遍采用酸洗法。但该法生产周期长，效率低，成本高。而振动电磁除铁不但可快速、高效、低耗地除去这类物料中的铁磁杂质，且操作简便。本文给出了所设计的除铁器的振幅、生产率及振体空间在励磁回路中所需的磁感应强度等基本设计参数，为结构设计提供了理论依据     

论社会主义民主发展道路和指导原则：学习邓小平社会主义民主建设思想

邓小平提出民族制度化、法律化思想，为我国民主建设健康发展提出了一条正确的发展道路。民主制度化、法律化的实践，有效地保障了人民民主权利，规范了人民行使民主权利的行为，使建设法治国家目标的实现了可靠的保证。为使我国民主建设实践在正确道路上顺利前进，邓小平还提出一系列的指导原则，强调社会主义民主建设，必须在共产党的领导下，有秩序地进行；必须从国情出发，切合中国实际；必须保证国家兴旺发达和长治久安。
