Aluminum （Al） toxicity often takes place in acidic soils with a pH of 5.5 or lower. Breeding and cultivation of Al tolerance wheat can partially protect wheat escaping from Al toxicity. The scarcity of the tolerant sources impedes the wheat breeding. In order to find new Al tolerance sources, we screened 173 bread wheat landraces from Tibet of China using hydroponic screening. It was indicated that：（1） There were diversities on the root regenerate length （RRL）. The RRL of a large of landraces were longer than 7.00 cm in pH 7 （58.38%） and pH 4.5 （66.47%）, but shorter than 5.00 cm in pH 4.5 ＋50μM Al^3＋（80.93%）. The low pH showed either promotion or restraining effects depend on landraces, but Al toxicity under low pH only showed restraining effects on the root elongation. （2） There were also diversities on root tolerance index of low pH （RTI 1） or root aluminum tolerance index （RTI2） among cultivars. The RTI1 varied from a narrow range but with relatively high value （0.8722-1.2953） in comparison with that of RTI2 （0.3829-1.0058）, and the RTI1 of approximately 60% landraces was higher than 1.0000, the RTI2 of only 19.07% landraces was higher than 0.7000, suggesting that Al toxicity acted as an important factor for the reduction of the root elongation under acidic soils. （3） The RTI 1 of many wheats was higher than 1.0000, and As2256 and As2295 were the most tolerant for low pH, with RTI1 1.2953 and 1.2925, respectively. （4） Based on RTI2, seven wheats showed similar or higher tolerance to Al toxicity than Chinese Spring （CS）, a known tolerance wheat. Much better tolerance existed in landraces of As1543 and As1242, which can be used as the new parents for Al tolerant breeding.

The sUdeway design is the key in the design of the disc vibrating feeder. However, no reliable theoretical guidance has come into existence, which greatly restricted the application of CAD（ Computer-aided design）. In order to feed the application of CAD technology, we must make improvements to the existing coding method. Based on the similarity principle of Group Technology and existing coding system, a new coding method applicable to slide- way design is brought forward. The existing coding system could get optimized by means of analysing and studying the influence imposed by the parts＇ shape and posture features. More detailed information about the parts could be supplied by the new coding system, which makes the design simpler, more convenient and more accurate with the subjoin of the initial and targeted codes.

AIM： To investigate the expression of SNC73, a transcript of the immunoglobulin α-1 gene （IgA1-H chain）, in human epitheliα-derived tumor cells. METHODS： Total RNAs and cell lysates were prepared from five different human epithelial cell lines derived from lung, stomach, liver, skin, and breast, respectively. RT-PCR and immunoblot analysis of these five cell lines were done. Both RT-PCR and immunochemistry were used to detect the expression of SNC73 in these cell lines. We also examined the expression of SNC73 in normal epithelial cells of colon mucosa by in situ hybridization. RT-PCR and immunoblot analysis were used to determine whether the recombination activating gene1/2 （RAG1 and RAG2） is present. The expression of three immunoglobulin transcription factors, EBF, E2A and Pax5, and the heavy chain of IgA1 and two types of light chains of immunoglobulin （κ and λ） in the aforementioned cell lines were analyzed by RT-PCR and immunochemistry, respectively. All the RT-PCR products were analyzed by sequencing. RESULTS： The results of RT-PCR and immunochemistry showed that both mRNA and protein of SNC73 were expressed in five human epitheliα-derived cancer cell lines. These data were further confirmed in the normal epithelial cells of colon mucosa by in situ hybridization. Also, the heavy chain of IgA1 and κ light chain were detected in these cells, but no λ light chain was observed. Both RAG1 and RAG2 were expressed in these human epitheliα-derived cancer cell lines and the sequence was identical to that expressed in pre-B and pre-T cells. In addition to RAG1 and RAG2, the mRNA in one of the immunoglobulin transcription factors, EBF, was also detected in these cell lines, and Pax5 was only expressed in SW480 cells, but no expression of E2A was observed in all the five cell lines. CONCLUSION： Immunoglobulin A1 is originally expressed and V（D）J recombination machine is also present in non-lymphoid cells, suggesting that V（D）J recombination machine mediates the assembly

公共文化机构的绩效评价问题是世界范围内的一道难题,因与我国现代公共文化服务体系建设目标和政府公共投入规模相关,近年来一直是政府、学界和社会三方共同关注的"风暴中心"。鉴于个案研究和定性分析较多而定量研究的缺失的现状难以提供政策层面上的学术支持,本文以公共图书馆行业为研究对象,通过引入多种DEA模型(CCR、BCC、FG、ST和WY)完成了对其绩效的定量评价。首先借助CCR和BCC模型对我国省域公共图书馆的综合效率、纯技术效率、规模效率进行了测算及分析,然后借助FG、ST、WY模型分析了规模收益状况及"拥挤"现象,并科学量化了"拥挤度"。评价结果显示我国公共图书馆整体服务效率有待提高,并且近几年效率持续下降,主要原因是技术管理水平不足和资源配置拥挤。对于公共图书馆效率持续下滑、资源配置呈现拥挤这一现实问题,改革图书馆管理制度的紧迫性要先于增加公共投入的要求。这一结果对公共政策意义是,近30年来一直行之有效的由增加公共投入引导业务发展的传统文化管理模式,正在失去效率,以后指望通过增加公共投入来提高公共机构的整体绩效的政策思路将越来越不适应现实状况,国家政策设计必须确立"公共投入的增幅与管理体制改革进程之间必须保持最低限度一致性"的基本原则。我国公共文化机构进入到一个以制度创新来提升整体服务效率的新时期。

风力发电塔是一种顶部有较大质量的细长高耸结构,基本周期一般较长,因此可能会在不同频谱特性地震动下呈现不同的破坏模式。为了研究该问题,该文针对某典型风电塔,使用ABAQUS建立精细有限元模型,基于规范反应谱选择两类不同特征周期(0.4 s和1.1 s)的地震动记录,进行非线性动力时程分析。结果表明,对于0.4 s特征周期的地震动,地震动能量远离风电塔基本周期,结构受高阶振型影响较大,虽然初始塑性铰出现在底部,但全截面塑性铰和倒塌出现在中上部;对于1.1 s特征周期的地震动,地震动能量更加靠近风电塔基本周期,因此结构主要受第一振型控制,初始塑性铰、全截面塑性铰和倒塌出现在底部。对于同一条地震动,可能由于峰值加速度不同引起破坏位置变化。

Transition metal-based nanomaterials have emerged as promising electrocatalysts for oxygen evolution reaction（OER）. Considerable research efforts have shown that self-reconstruction occurs on these nanomaterials under operating conditions of OER process. However, most of them undergo incomplete reconstruction with limited thickness of reconstruction layer, leading to low component utilization and arduous exploration of real catalytic mechanism. Herein, we identify the dynamic behaviors in complete reconstruction of Co-based complexes during OER. The hollow phytic acid（PA） cross-linked CoFe-based complex nanoboxes with porous nanowalls are designed because of their good electrolyte penetration and mass transport ability, in favor of the fast and complete reconstruction. A series of experiment characterizations demonstrate that the reconstruction process includes the fast substitution of PA by OH-to form Co（Fe）(OH)xand subsequent potential-driven oxidation to Co（Fe）OOH. The obtained CoFeOOH delivers a low overpotential of 290 mV at a current density of 10 mA cm-2and a long-term *** experiment results together with theory calculations reveal that the Fe incorporation can result in the electron rearrangement of reconstructed CoFeOOH and optimization of their electronic structure,accounting for the enhanced OER activity. The work provides new insights into complete reconstruction of metal-based complexes during OER and offers guidelines for rational design of high-performance electrocatalysts.
