Journal of Integrative Agriculture 2013年第7期12卷 1258-1266页

A pretreatment process for hydrogen peroxide （H2O2） was optimized to enhance the biodegradation performance of rice straw and increase biogas yield. A determination experiment was conducted under predicted optimal conditions. Optimization was implemented using response surface methodology. The effects of biodegradation and the interactive effects of pretreatment time （PT）, H2O2 concentration （HC）, and substrate to inoculum ratio （S/I） on methane yield were investigated. The lignin, cellulose, and hemicellulose of rice straw were significantly degraded with increasing HC. The optimal conditions for the use of pretreated rice straw in anaerobic digestion were a 6.18-d PT, 2.68% HC （w/w total solid）, and 1.08 S/I; these conditions result in a methane yield of 288 mL g-1 volatile solids （VS）. A determination coefficient of 95.2% was obtained, indicating that the model used to predict the anabolic digestion process has a favorable fit with the experimental parameters. The determination experiment resulted in a methane yield of 290 mL g-1 VS, 88.0% higher than that of untreated rice straw. Thus, H2O2 pretreatment of rice straw can be used to improve methane yields during biogas production.

Well-defined poly(ionic liquid) brushes with tunable wettability are successfully synthesized via nitroxide-mediated radical polymerization.X-ray photoelectron spectroscopy,attenuated total reflection infrared spectroscopy and static water contact angle measurements are used to monitor each ***,nuclear magnetic resonance(1H and 13C) spectra and gel permeation chromatographic measurements reveal that there is a linear increase in polymer film thickness with polymerization time,indicating that chain growth from the surface is a controlled/"living" *** surface morphology was measured by atomic force ***,the surfaces of the poly(ionic liquid) brushes with tunable wettability and reversible switching between hydrophilicity and hydrophobicity can be easily achieved by counteranion exchange.

藏文闻法录文献研究

闻法录是为证明所传教法之合理性而撰写的一种特殊的文献类型。该类文献肇始于公元8世纪末的吐蕃僧诤及诸多禅宗典籍被译成藏文的背景下,而敦煌藏文文献P.T.996号可视为闻法录文本的原始雏形。公元11世纪时西藏出现新旧密续派之争,加之... 详细信息

闻法录是为证明所传教法之合理性而撰写的一种特殊的文献类型。该类文献肇始于公元8世纪末的吐蕃僧诤及诸多禅宗典籍被译成藏文的背景下,而敦煌藏文文献P.T.996号可视为闻法录文本的原始雏形。公元11世纪时西藏出现新旧密续派之争,加之文本传规(lung rgyun)观念在西藏的兴盛,到12世纪时喇嘛尚(bla ma zhang brtson vgrus grags pa)撰写了其《闻法录》(《brgyud pa sna tshogs》和《rtsa bavi bla ma sna tshogs kyi vthob byang》)之后,这类文献方才成为一种独立的文本类型而一直延续至今。其内容包含闻法者的师承及其主要上师和弟子的生平等诸多历史信息,是研究藏传佛教历史和汉藏文化交流的重要历史资料。本文采用文献分析和比较研究的方法,对闻法录的写作目的及背景、雏形、名称、种类、发展阶段等进行了概述。

早在十九世纪初，猪萎缩性鼻炎被定义为一种由细菌感染而引发的传染性疾病（Franque，1830-德国）。迄今为止，猪萎缩性鼻炎已有差不多两个世纪的历史，而其感染性病原学是在一个世纪以后（二十世纪初）才被人们清楚地认识（Ratke，1938；Carlstrom，1940）。目前世界各地的养猪场仍然会出现萎缩性鼻炎的临床症状。
