Electrochemical nitrogen reduction reaction(NRR)paves a new way to cost-efficient production of ammonia,but is still challenging in the sluggish kinetics caused by hydrogen evolution reaction competition and chemical inertness of N≡N ***,we report a“dual-site”strategy for boosting NRR performance.A high-performance catalyst is successfully constructed by anchoring isolated Fe and Mo atoms on hierarchical N doped carbon nanotubes through a facile self-sacrificing template route,which exhibits a remarkably improved NH3 yield rate of 26.8μg·h^(−1)·mg with 11.8%Faradaic efficiency,which is 2.5 and 1.6 times larger than those of Fe/NC and Mo/*** enhancement can be attributed to the unique hierarchical structure that profits from the contact of electrode and electrolyte,thus improving the mass and electron *** importantly,the in situ Fourier transform infrared spectroscopy(in situ FTIR)result firmly demonstrates the crucial role of the coupling of Fe and Mo atoms,which can efficiently boost the generation and transmission of*N2Hy intermediates,leading to an accelerated reaction rate.

STUDIES IN MENTAL LEXICON AND The IMPLICATIONS FOR ENGLISH VOCABULARY TEACHING

引用

Chinese Journal of Applied Linguistics 1998年第2期21卷 69-72页

作者： he jianing Guangdong University of Foreign Studies

Introduction Vocabulary is one of the indispensable components of the language system, and researchers have found that there exists a close relationship between vocabulary and other components in a language system. However, vocabulary is thought to be the most difficult component of language knowledge for a learner to grasp. Gorman (1979) pointed out that there was evidence showing that as students become more proficient in a second language, problems caused specifically by syntactical variation become less significant (cited in Crow and Quigley, 1985: 499). That is to say, vocabulary becomes a major problem in

CENP-K and CENP-H may form coiled-coils in the kinetochores

引用

Science China(Life Sciences) 2009年第4期52卷 352-359页

作者： QIU ShuLan, WANG jianing, YU Chuang & he DaCheng The Key Laboratory for Cell Proliferation and Regulation Biology of the Ministry of Education, Beijing Normal University, Universities’ Confederated Institute of Proteomics, Beijing 100875, China The Key Laboratory for Cell Proliferation and Regulation Biology of the Ministry of Education Beijing Normal University Universities’ Confederated Institute of Proteomics Beijing China

Kinetochores are large proteinaceous structure on the surface of chromosomes’ primary constriction during mitosis. They link chromosomes to spindle microtubules and also regulate the spindle assem- bly checkpoint, which is crucial for correct chromosome segregation in all eukaryotes. The better known core networks of kinetochores include the KMN network (K, KNL1; M, Mis12 complex; N, Ndc80 complex)and CCAN (constitutive centromere-associated network). However, the detailed molecular mechanism of the kinetochore protein network remains unclear. This study demonstrates that CENP-H and CENP-K form quite stable subcomplex by TAP (tandem affinity purification) with heK 293 cells which express TAP-CENP-K, with the ratio of purified CENP-H and CENP-K being close to 1︰1 even with high salt. Bioinformatic analysis suggests that CENP-H and CENP-K are enriched with coiled-coil regions. This implies that CENP-H and CENP-K form heterodimeric coiled-coils. Furthermore, the func- tional regions which form the complex are respectively located on their N- and C-terminals, but the association between the C-terminals is more complex. It is possible that this is the first identified het- erodimeric coiled-coils within the inner kinetochore, which is directly involved in the attachment be- tween kinetochores and the spindle microtubules.

肌肉通过肌腱、韧带附着于骨骼,附着位点的形态改变与肌肉功能相关,因而被用于古代人群肢体功能活跃度的复原。本文对东周时期军都山古代人群股骨的臀中肌、髂腰肌、腓肠肌内侧头三个纤维软骨性附着位点的形态进行了观测,并与清代君子村组进行对比,检验其形态变化与组别、性别、年龄、体型的相关性。结果表明,部分附着位点的形态改变随年龄而增加,但性别、体型及组别差异对附着位点形态变化的影响较小。这与很多上肢研究中发现的附着位点形态受性别、体型、劳动强度等影响结论不同。这种差别可能来自下肢承重以及更为复杂的功能状况等原因,军都山与君子村样本年龄结构的不一致性也是一个重要影响因素。对于古代人群下肢肌腱附着位点形态变化与其功能状况的关系需要更深入的探讨。

古代畜牧生计人群的生活方式、对畜牧业依赖程度及与相邻定居人群的关系表现多样。军都山墓地是东周时期以畜牧业为重要生计方式的玉皇庙文化代表性遗址,在其延续的近三百年时间里文化遗存发生了一些明确变化,暗示其生活模式的可能改变。本文通过该遗址出土人骨体质状况的表现对军都山古人群运动和生活方式的时序性变化进行探讨。106根股骨骨干中部断面生物力学参数被用来分析其下肢功能状况及流动性,2487枚牙齿的龋病发生情况用于了解其植物性食物摄入的变化趋势。结果表明,与放牧生活密切相关的流动性在男性随时代明显减弱,但一直显著高于同性别农业定居人群;女性的流动性则变化不大,与定居农业人群相当。龋齿发病在男性随时代显著增高,女性则变化不明显且维持在相对较高水平,表明男性饮食中粮食类占比随时代有增加的趋势。结合文化遗存的发展变化推断,虽然畜牧业一直是军都山古代人类最重要的生计模式,但其流动性和龋病的变化表明畜牧业在其生业模式重要性随时代有所下降;伴随其的是农业在其经济生活中的比重开始增加,可能是受周边定居农业文化影响的结果。
