The high-efficient degrading ability of Fe BC amorphous ribbons toward acid orange 7(AO7)via redox reactions is reported and compared with that of Fe PC amorphous *** time required for degrading50%of AO7 using Fe BC amorphous ribbons is only 1/3 of that using Fe PC amorphous *** the Fe BC amorphous matrix,galvanic cell structures are formed between the Fe-B and Fe-C bonds because of the large difference in their bonding strengths,which contributes to the low reaction activation energy and the high degrading efficiency of Fe BC amorphous *** extremely long service life of Fe BC amorphous ribbons comes from the progressive formation of 3 D porous nanosheet networks that allow more efficient mass transport and a larger specific surface *** Fe BC amorphous ribbons show a satisfying degrading ability in not only acidic but also neutral and weak alkaline AO7 *** work provides an effective and environmental-friendly material for degrading azo dyes.

Objective: To investigate the distributions of human leukocyte antigen (HLA)-A and-B alleles and HLA-A-B haplotypes in the Yi ethnic minority of the Yunnan Province, situated in southwestern China. Methods: DNA typing for HLA-A and-B loci was performed using the polymerase chain reaction-sequence-based typing (PCR-SBT) method on 114 randomly selected healthy individuals of the Yi population. The allelic frequencies of HLA-A and-B loci were calculated by direct counting and HLA-A-B haplotypes were estimated using the expectation maximization algorithm. Results: A total of 17 HLA-A and 38 HLA-B alleles were found in the Yi population. The most frequent alleles were A2402 (32.46%), A1101 (26.32%), and A0203 (10.09%) at the HLA-A locus and B4601 (12.28%), B1525 (10.09%), B4001 (8.77%), and B3802 (7.89%) at the HLA-B locus. The predominant HLA-A-B haplotypes were A2402-B1525 (7.86%) and A0203-B3802 (5.64%), followed by A1101-B4001 (4.69%). Phylogenetic analysis indicates that the Yi population in the Honghe, Yunnan Province of China basically belongs to groups of southeastern Asian origin, but shares some characteristics with northeastern Asian groups. Conclusion: The present study may add to the understanding of HLA polymorphism in the Yi ethnic group that was poorly defined previously, and provide useful information for bone marrow transplantation, anthropological research, and forensic sciences as well as for disease-association studies.

The gas gain and energy resolution of single and double THGEM detectors （5 cm×5 cm effective area） with mini-rims （rim less than 10 um） were studied. The maximum gain was found to reach 5×103 and 2 × 105 for single and double THGEMs respectively, while the energy resolution for 5.9 keV X-rays varied from 18% to 28% for both single and double THGEM detectors of different hole sizes and thicknesses. Different combinations were also investigated of noble gases （argon, neon） mixed with a quantity of other gases （isobutane, methane） at atmospheric pressure.

为探究水泵水轮机转轮和导水机构的动应力特性,通过建立水泵水轮机导水机构(固定导叶与活动导叶)及转轮的固体域模型,并基于流固耦合的方法对转轮、导水机构在水泵水轮机发电、抽水等多工况展开计算分析,以获得转轮及导水机构的应力特性。计算结果表明:转轮叶片与上冠“T”型连接处的应力集中与转轮进口处旋涡发展状态有关;转轮与活动导叶间的动静干涉是无叶区压力脉动的主要来源,且主频为叶片通过频率;较小开度或低水头工况下机组运行靠近不稳定区,活动导叶与转轮的动应力均较大,但活动导叶对水流的约束引导作用使其动应力值相比于转轮更高,且流量的增大有利于降低转轮所受动应力。因此可考虑通过改变导叶尾端与转轮进口间距,调整无叶区宽度或调整机组运行区域,避免长时间运行在低负荷、小开度工况下可进一步改善转轮所受动应力情况。
