An efficient method for the synthesis of N-Cbz-β-aminoalkanesulfonamides was described.N-Cbz-β-aminoalkanesulfonamides were readily prepared in good yields from a variety of amino alcohols,including optically active ones,via N-Cbz protection with benzyl chloroformate,Mitsunobu esterification reaction with thiolacetic acid,N-chlorosuccinimide oxidation,and ammonolysis process.

With the high penetration of renewable energy sources,the reliability of power systems becomes more vulnerable than ever because of the greater uncertainty and intermittence in power *** power plays an important role in the power system reliability,because it is closely related to the system voltage stability and voltage ***,reactive power-related reliability issues are seldom emphasized in conventional power reliability *** article investigates power system reliability of real and reactive *** and reactive power shortages and the associated voltage violations due to system failures are considered on reliability evaluation of power systems.A three-stage load-shedding technique for post contingencies is implemented to determine the contributions of real and reactive power on the system reliability and to find an optimal way to release network *** results provide the detailed information on power system planning and operation for system planners and operators from real and reactive power aspects.

In this study, we investigated the effects of dexamethasone, pertussis toxin （a Gi protein inhibitor） and actinomycin （a transcription inhibitor） on serum nitric oxide synthase activity and nitric oxide content in a rat model of lung disease-induced brain injury. High-dose dexamethasone （13 mg/kg） and dexamethasone ＋ actinomycin reduced lung water content, increased serum nitric oxide synthase activity and nitric oxide content, diminished inflammatory cell infiltration in pulmonary alveolar interstitium, attenuated meningeal vascular hyperemia, reduced glial cell infiltration, and decreased cerebral edema. These results demonstrate that high-dose glucocorticoid treatment can reduce the severity of lung disease-induced brain injury by increasing nitric oxide synthase activity and nitric oxide levels.

The dawn of the 21st century saw images of intellectuals in novels change in a drastic ***,and those in the humanities in particular,are no longer portrayed as privileged Enlightenment thinkers or sages with Confucian ideas of *** the novels that take intellectuals as their subject matters,such characters often end up involved in betrayal,self-exile,or spiritual/mortal *** is not a historical process,nor an inevitable course for intellectuals to be sure,but it remains a legitimate question to ask why these fictional intellectuals are becoming,more often than not,new tragic *** are they becoming misfits in their society and ending up in exile,abandonment,and even death?The present paper examines different images of intellectuals and the makings of their destinies.

With the non-equilibrium Green’s function method and density functional theory, we have studied the electronic properties of trigonal graphene nanoribbons, with Fe terminal and H terminal, coupled to gold electrodes. Rectification behavior can be observed when the electrode-molecule contact distance is larger than 2.2 Å. The electronic transport is greatly improved in case of Fe terminal which is analyzed in terms of transmission spectra and density of states.

一、从加缪《沉默的人们》说起最初对加缪的了解,始于八十年代。那时,中国20世纪第二次"欧风东渐"正风起云涌,"现代派文学"有如石破天惊般地席卷中国文坛。那时的加缪是"现代派文学"的大师,他的名声虽然没有萨特更耀眼,但他的《鼠疫》《局外人》等小说,对那个时代中国作家的影响仍然巨大无比。后来,我在一些材料上还可以感受到加缪在一些作家那里的深刻影响。

新世纪十年,中篇小说是成就最大的文体,它可谓代表了白话小说诞生以来的最高艺术成就。长篇小说因市场需求,出版的门槛越来越低,良莠不齐是其突出的特征;短篇小说没有得到应有的重视,在不断萎缩,而中篇小说因为发表刊物并没有降低艺术质量迁就市场,多种因素决定了这个文体一直在文学高端不断发展。因此,新世纪十年中篇小说数量之多、质量之稳定,都是其他文体难以比及的。它所表达的不同阶段的理想、焦虑、矛盾、彷徨、欲望或不确定性,都密切地联系着这个时代的社会生活和心理经验。

2009年的中篇小说仍然有许多优秀作品。更重要的是有思想和艺术能力的作家为我们提供了新的文学经验。但是,就在一些最有光彩的作品中,我们仍看到其间"同质化"的问题。作为单篇故事它们都很出色,特别是构思,内容奇崛、逻辑严密又出人意料。但这些作家结构小说的基础都是依仗于一个道具,小说就这样准确地镶嵌在这些物体上。这种过于小说化或戏剧化的倾向,从一个方面表达了当下作家与生活的关系。它的问题是:这些小说太像小说了。
