| 1 | 基于响应面法的AA5052-H32铝合金搅拌摩擦焊参数优化(英文)显示文摘采用中心组合设计响应面方法对AA5052-H32铝板间的搅拌摩擦焊过程进行优化。研究发现,焊接参数如搅拌头形状、搅拌头转速、焊接速度和搅拌头倾斜角对接头性能起着决定作用。采用方锥形搅拌头,在搅拌头转速为600 r/min、焊接速度为65 mm/min和搅拌头倾角为1.5°时,得到最优的焊接效率93.51%。开发数学模型描述焊接参数和响应变量(极限抗拉强度和伸长率)间的关系,并对模型进行优化,以最大限度地提高搅拌摩擦焊接头的极限抗拉强度。利用数学模型生成响应曲线以解释焊接参数对响应变量的相互影响,并采用方差分析(ANOVA)验证模型的可靠性。结果表明,实验数据与预测模型吻合较好。通过观察焊缝的微观和宏观结构,研究焊缝不同区域的晶粒组织。 | S.SHANAVAS J.EDWIN RAJA DHAS | 2017 | Transactions of Nonferrous Metals Society of China2017，27，11： | 8 |
| 2 | Bacteriocin from Bacillus subtilis as a novel drug against diabetic foot ulcer bacterial pathogens显示文摘Objective:To isolate and identify Bacillus subtilis(B.subtilis)from soil and to characterize and partially purify the bacteriocin.To evaluate the antimicrobial activity against four diabetic foot ulcer bacterial pathogens.Methods:Genotypic identification was done based on Sergey's manual of systemic bacteriology.Antimicrobial susceptibility test was done by Kirby-Bauer disc diffusion method.Colonies were identified by colony morphology and biochemical characterization and also compared with MTCC 121 strain.Further identification was done by 16S rRNA sequencing.Inhibitory activities of partially purified bacteriocin on all the DFU isolates were done by agar well diffusion method.The strain was identified to produce bacteriocin by stab overlay assay.Bacteriocin was extracted by organic solvent extraction using chloroform,further purified by HPI.C and physical,and chemical characterization was performed.Results:The four isolates showed high level of resistance to amoxyclav and sensitivity to ciprofloxacin.HPLC purification revealed that the extracts are bacteriocin.The phylogenetic tree analysis results showed that the isolate was 99%related to B.subtilis BSF01.The results reveled activity to all the four isolates and high level of activity was seen in case of Klebsiella sp.Conclusions:Partially purified bacteriocin was found to have antimicrobial activity against the four diabetic foot ulcer bacterial pathogens,which can thus be applied as a better drug molecule on further studies.The strain B.subtilis are found to be safe for use and these antimicrobial peptides can be used as an antimicrobial in humans to treat DFU bacterial pathogens. | Baby Joseph Berlina Dhas Vimalin Hena Justin Raj | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，12： | 2 |
