门尼黏度是橡胶加工和生产过程的重要控制指标,反映橡胶加工性能的好坏和分子量高低及分布范围宽窄。在丁苯橡胶的生产过程中,主要通过控制聚合单元的胶乳门尼黏度来控制最终产品质量。因此,胶乳门尼黏度分析的准确性对生产过程控制显... 门尼黏度是橡胶加工和生产过程的重要控制指标,反映橡胶加工性能的好坏和分子量高低及分布范围宽窄。在丁苯橡胶的生产过程中,主要通过控制聚合单元的胶乳门尼黏度来控制最终产品质量。因此,胶乳门尼黏度分析的准确性对生产过程控制显得尤为重要。以SBR1500E和SBR1502两种牌号的胶乳为研究对象,详细探讨了不同种类的絮凝剂、不同种类的防老剂以及防老剂的添加量3个因素对胶乳门尼黏度分析的影响。该实验研究为提高胶乳制样分析门尼黏度的准确性及稳定丁苯橡胶产品优级品率提供了参考。 展开更多

AIM: To study the polymorphisms of toll-like receptor 4 (TLR4) gene Asp299Gly, Thr399Ile and TLR2 gene Arg753Gln, Arg677Trp and susceptibility to inflammatory bowel disease (IBD) in the Zhuang population from Guangxi,... AIM: To study the polymorphisms of toll-like receptor 4 (TLR4) gene Asp299Gly, Thr399Ile and TLR2 gene Arg753Gln, Arg677Trp and susceptibility to inflammatory bowel disease (IBD) in the Zhuang population from Guangxi, China. METHODS: A case-control study was performed from February 2007 to October 2011 which included 146 Zhuang patients with IBD in the experimental group and 164 healthy Zhuang subjects who acted as the control group. All patients and healthy subjects were from the Guangxi Zhuang Autonomous Region of China. Genomic DNA was extracted from intestinal tissue by the phenol chloroform method. TLR4 gene Asp299Gly, Thr399Ile and TLR2 gene Arg753Gln, Arg677Trp were amplified by polymerase chain reaction (PCR), and then detected by PCR-restriction fragment length polymorphism (RFLP). RESULTS: The TLR4 gene Asp299Gly was digested using Nco Ⅰ restriction enzyme, and a single band of 249 bp was observed which showed that it was a wild type (AA). The TLR4 gene Thr399Ile was digested using Hinf Ⅰrestriction enzyme and only the wild type (CC) was detected. In addition, the TLR2 gene Arg-677Trp was digested using Aci Ⅰ restriction enzyme and only the wild type (CC) was detected. The TLR2 gene Arg753Gln was digested using Pst Ⅰ restriction enzyme. Only the wild type (GG) as a single band of 254 bp was observed during RFLP. Overall, no heterozygous or homozygous single nucleotide polymorphism mutations were found in patients with Crohn's disease and ulcerative colitis both in the TLR4 gene Asp299Gly, Thr399Ile and the TLR2 gene Arg677Trp, Arg753Gln in the Zhuang population from the Guangxi Zhuang Autonomous Region of China. CONCLUSION: The TLR4 gene Asp299Gly, Thr399Ile and TLR2 gene Arg753Gln, Arg677Trp polymorphisms may not be associated with IBD in the Zhuang population from the Guangxi Zhuang Autonomous Region of China. 展开更多

The paper presents the results of research on innovation activities of manufacturing firms in Serbia. In order to answer the question how innovation takes place in one transition country, key influencing factors were identify (i.e., firm's size, age, ownership, industry sector, personnel qualifications and experience). Based on the analysis of a sample comprising 73 firms, the study tried to highlight certain innovation barriers, which may have a negative impact on the total efficiency of economic performance, and growth and development of manufacturing firms in Serbia. Comparing overall innovation activities of Serbian firms to the other transition countries, it can be concluded that majority of the fhnns had innovation performances below the level EU-27. This study draws out the potential contributions to existing literature of managing innovation in Serbia. 展开更多
