原生态文化与中国传统

第九届人类学高级论坛于2010年6月23～25日在贵州省凯里学院举行。会议期间,《光明日报》国学版主编梁枢先生组织了一个关于"原生态文化与中国传统"的小型座谈会,会议由广西民族大学徐杰舜教授主持,参加人员有中国人民大学郑杭生教授、中国社会科学院叶舒宪研究员、四川大学徐新建教授、厦门大学彭兆荣教授、中国人民大学陆益龙副教授、浙江师范大学林敏霞博士等。座谈会就原生态文化与中国传统文化尤其是国学的关系展开了深入探讨

Cloning,expression,purification and characterization of thermostable and acid-stable α-amylase from Thermococuus HJ21

通过简并引物扩增热球菌（Thermococcus siculi）HJ21高温α-淀粉酶保守区域之间的序列,再利用Site-finding技术获得两端未知序列。构建了在N端添加了His6标签的表达载体pEt-28a-His6-THJA后转化E.coli,在IPTG诱导下表达。进一步纯化后SDS-PAGE电泳检测达到电泳纯,重组酶分子量为50 KDa。重组酶最适作用温度和pH值分别为90℃,pH5.0。重组酶在pH为5.5时最稳定;K＋,Sr2＋,Mg2＋,Na＋对α-淀粉酶活力的促进作用不显著,Cu2＋,Pb2＋,Hg2＋,Zn2＋,N-溴代丁酰亚胺和三氯乙酸对该酶有显著抑制作用

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
