An Analysis on the Concept and Intension of Recissive Leader and Their Change in China

内隐领导理论是关于人们内心领导概念结构的探究。本研究通过比较分析2002年与1988年的调查统计结果，发现当前中国人内心领导概念的内容仍由个人品德、目标有效性、人际能力和才能多而性四个因素构成，但四因素的方差、信度、排序及构成项目已发生了显著变化，这表明不同时代的社会文化变迁对中国内隐领导理论产生了一定的影响

Research on Two Ballasting Schemes for Ore Carriers in Half Laden Condition

为防止半载情况下矿砂船在大风浪中因操纵性能差出现摇荡剧烈的现象,以-艘半载2 ×10^4 t 精铁矿的矿砂船压载方案设置为实例,从船舶总纵强度校核和油耗效能等方面对部分压载和平行压载进行 了比较.计算结果表明,两种方案均满足船舶总纵强度的安全要求,但部分压载方案的排水量较小,能有 效降低船舶油耗,具有现实的推广意义.In this paper, we choose the example of a 20000-dwt fine ore carrier to discuss its two ballast-ing plan schemes, namely partial and parallel ballast ing, in order to prevent the ore carrier from danger in se-vere waves from dangers. The longitudinal strengths of the ship and fuel consumption performances are com-pared for those two ballast schemes. Calculations show that both schemes can satisfy the requirements of the safety of the ship in terms of the total longitudinal strength. However, the displacement of the ship is smaller in the partial ballasting scheme, hence increasing fuel consumption efficient. So this scheme is more practical.福建省自然科学基金项目（2015J01214

利用抗草鱼IgM的单链抗体分析草鱼呼肠孤病毒的免疫原性

草鱼是中国重要的淡水养殖鱼种之一,草鱼呼肠孤病毒(GCRV)可引起一龄草鱼出现致命性的出血性疾病,严重影响草鱼养殖业的健康发展.目前,在草鱼中尚未建立一种有效的检测该病毒结构蛋白抗原性质的方法.本研究采用已构建的小鼠天然噬菌体展示抗体文库淘选得到可以特异性识别草鱼IgM的单链抗体,并在已鉴定的单链抗体阳性克隆中,筛选出对草鱼IgM有较好的特异性结合活性的单链抗体C1B3.ELISA分析表明,在感染草鱼出血病病毒5～7天后,感染组比对照组血清中IgM的含量增加了2倍多.进一步的Western blot结果显示,已感染病毒草鱼血清中的IgM能特异地识别草鱼的外壳蛋白VP7.结果表明,VP7相对于病毒的其他结构蛋白而言在草鱼中能产生更强的免疫反应,提示VP7应是用于疫苗设计的首选抗原

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
