Laboratory study of property-modified prebaked carbon anode and application in large aluminum electrolysis cells

A kind of complex additive mainly containing Al, Mg, F, and O was prepared. The synthetical performances of the property-modified prebaked anodes containing additives were tested in laboratory. On the basis of ideal testing results obtained, a large number of industrial prebaked property-modified anodes are prepared in a large-scale aluminum company. Further more, they are all used in 160 kA prebaked anode aluminum electrolysis cells. The statistic result show that, compared with common anodes, the property-modified ones enhance current by 11.6 kg per ton aluminum averagely.     

Effect of Tongmai Decoction on expression of NF-κB in ox-LDL injured endothelial cells

Objective Study on the effect of NF-κB in ox-LDL injured HUVEC-304 and the intervention with the serum of Tongmai Decoction. Methods Tongmai Decoction herbage-contained serum was made by the serum pharmacology methods, then the HUVEC-304 cells were divided into 5 groups and incubated for 24 h: 1) normal group;2) fetal calf serum group; 3) ox-LDL group; 4) simvastatin group; 5) Tongmai Decoction group. RT-PCR was used to determine the mRNA of NF-κB in the cells, Western Blot Assay was used to determine the protein content of NF-κB in the cells. Results 1) Compared with the cells in normal group and serum control group , the endothelial cells in ox-LDL group are seriously injured, while those in Tongmai Decoction group grow better; 2) Compared with the cells in normal group and fetal calf serum group, the expressions of NF-κB gene and protein are up-regulated in ox-LDL group(P＜0.05, P＜0.01); 3) Compared with the cells in ox-LDL group, the expression of NF-κB gene and protein in Tongmai Decoction group are significantly down-regulated, there is no difference between Tongmai Decoction group and simvastatin group(P＞0.05). Conclusion Tongmai Decoction can protect the injured endothelial cells, up-regulate the expressions of NF-κB gene and protein content.

论我国大学不良竞争的形成及控制

大学在办学资源、办学过程、办学质量、办学形象的竞争中出现大量的不良倾向。大学的不良竞争是由于政府主导资源配置、资源和制度供给不足、大学系统重构等因素导致。必须通过控制主体、控制手段的转变和控制对象的发展形成新的控制机制，以保证大学竞争的秩序化和规范化。     

指导我国房地产市场良性发展的理论基础--解读国务院18号令

自国务院<关于进一步深化城镇住房制度改革加快住房建设的通知>(国发[1998]23号)文发布以来,我国城镇住房制度改革不断向纵深推进,居民住房需求的不断提高促使居民住房观念发生重要转变,居民住房消费有效启动,住房商品化的新体制基本确立,房地产市场体系逐步建立,房地产投资持续快速增长,以住宅为主的房地产业已经成为国民经济的支柱产业.2003年,国务院就进一步推动和促进我国房地产业的持续健康发展下发了<关于促进房地产市场持续健康发展的通知>(以下简称国务院l 8号令),明确提出房地产业是关联度高、带动力强、涉及面广的国民经济支柱产业.这一重要判断对于我们认识房地产市场的现状,确定正确的方针政策,促进房地产业持续健康发展具有重要意义.国务院18号令是指导房改和房地产工作的重要文件,对于促进房地产市场持续健康发展必将产生积极作用,我国房地产将迎来新的春天.
