Non-linear 2-DOF model and centre manifold theory to study limit cycle oscillations caused by drum-brake judder

This paper presents the research on the laws of systematic-parameter dependent variation in the vibration amplitude of drum-brake limit cycle oscillations (LCO). We established a two-degree non-linear dynamic model to describe the low-frequency vibration of the drum brake, applied the centre manifold theory to simplify the system, and obtained the LCO amplitude by calculating the normal form of the simplified system at the Hopf bifurcation point. It is indicated that when the friction coefficient is smaller than the friction coefficient at the bifurcation point, the amplitude decreases; whereas with a friction coefficient larger than the friction coefficient of bifurcation point, LCO occurs. The results suggest that it is applicable to suppress the LCO amplitude by changing systematic parameters, and thus improve the safety and ride comfort when applying brake. These findings can be applied to guiding the design of drum brakes.     

校园暴力的成因分析及教育对策

校园暴力又称反学校文化，指的是与学校主流文化相对立的一种文化，它所倡导的价值标准与行为规范与学校的主导价值规范相悖。校园暴力具有显性化、多样化、强烈化、长期化、低龄化特征。其教育方面的原因有学校文化形式与实质的背离，家庭教育的缺失，教师权威地位颠覆，学生群体文化的兴盛等方面。笔者认为消除校园暴力的对策有：倾力打造书香校园，激活学校德育，优化家庭教育以及调控学生群体文化。     

论非语言行为的语义特征

非语言交际是不用词语的交际 ,是在特定的情景或语境中使用非语言行为交流和理解信息的过程。非语言行为形式众多 ,内容丰富 ,地域性强 ,民族文化背景制约着非语言行为的内涵。非语言行为既有先天本能性 ,又有后天习得性 ;既有自觉性 ,又有不自觉性 ;既有确切含义的 ,也有示意模糊的 ;既有语境敏感性、多义性 ,又有同义性和反义性。

In vitro study on ribozyme against hepatitis C virus

Objective: To determine the effective nucleotide sites of ribozymes against HCV, and obtain a highly effective, nontoxic and inexpensive antisense ribozyme specific for HCV. Methods: Two effective ribozymes, targeted to HCV 5’NC region and C region, were designed and synthesized. Eukaryotic expression vectors, pSV2-gpt. CD-SR (, containing either HCRZNC or HCRZC were constructued and transfected into MT-2 cells, which had been infected by HCV. Quantitative PCR and hydridization were used to determine the effect of inhibition of HCV by ribozymes. Results: HCRZNC and HCRZC suppressed the replication of HCV by 54.7% and 62.1%, respectively. Furthermore, when both ribozymes were cotransfected into cells, they suppressed replication by 78.8%. Conclusion: Two specific antisense ribozymes have strong inhibitory effects on the replication of HCV in cultured cells, and have better effect when used together.
