AtPEPTIDE RECEPTOR2 （AtPEPR2） is a member of leucine-rich repeat receptor-like kinase family and binds to a group of AtPROPEP gene-encoded endogenous peptides, AtPeps. Previously, we found that AtPEPR2 plays a moderate role in the AtPep1-mediated innate immunity responses in Arabidopsis leaf. In this study, we found that AtPEPR2 promoter has strong activity in the vascular tissues of the roots and the atpepr2 mutants showed a moderate but significantly shorter root phenotype. AtPEPR2 partial y mediated AtPep1-induced root elongation inhibition. AtPep1-triggered cytosolic Ca2t transient rise in roots showed partial dependence on AtPEPR2 and ful y on extracellular Ca2t （[Ca2t]ext）. Transcriptional profiling analysis found that expression of 75% of AtPep1-modulated genes in roots was ful y dependent on AtPEPR2, of which two dramatical y induced genes showed partial dependence on the [Ca2t]ext. Arabidopsis genome contains seven Glutamine Dumpers genes （AtGDUs）, encoding amino acid exporters. Three of them （AtGDU2, 3, 5） were among the top 10 genes that were＆amp;nbsp;downregulated by AtPep1 through AtPEPR2 ful y dependent pathway. Treatment with AtPep1 strongly suppressed pro-moter activity of AtGDU3 in roots, which was relieved by chelating [Ca2t]ext. Arabidopsis overexpressing AtGDU3 showed a shorter root phenotype and decreased sensitivity to the AtPep1-mediated inhibition of root elongation. Taken together, this study demonstrated a significant role of AtPEPR2 in the AtPep1-mediated signaling in the roots.

动物史的内涵与价值

文章反思了动物史这一新兴史学领域,并提出了动物史研究的主要论点与未来任务。文章的主要目标是明确苏珊·南斯主编的《历史中的动物》给动物史研究带来的新前景和可能性。这些研究前景和可能性体现在,从动物的视角理解动物中介(将动物看作认识历史的中介和历史中的行动者);在“以人类为中心”的档案中寻找动物的痕迹,并搜集有关动物记述的历史资料。文章还讨论了动物史研究在方法论上面临的困难,尤其是探索动物历史过程中人文社会科学与生命科学合并的可能性。这篇评论思考了动物史研究如何推动学术界反思历史学的学科基础问题。一些学术反思来自于主张彻底进行跨学科研究的学者,其中许多是历史学家。这些学者不仅致力于将历史学与动物心理学、生态学、行为学、进化生物学和动物学等学科结合,而且对历史学科的基本假设提出了质疑:历史学家获得的建构过去知识的地位以及这类知识的认识论地位。在这种语境中,出现了若干问题:我们能否实现“物种间的能力”(埃丽卡·富奇的术语),以创造有关过去的多物种知识?对动物感知变化的研究能否帮助我们提出看待过去的非历史路径?我们能够以多物种的作者身份想象过去的解释吗?

Investigation of drying characteristics of low rank coal of bubbling fluidization through experiment using lab scale

Lignite is a low rank coal which is evenly distributed throughout the world and accounts for 45% of the total coal reserves. As it has a higher moisture content, its moisture content must be reduced in order to utilize it in power plant. In the present work, experiments on lignite has been done using a lab scale fluidized-bed reactor. Drying lignite through fluidized-bed reactor has a higher drying rate because there is good contact between particles and gas in the fluidized-bed reactor. Fluidized-bed drying can use air of 1.5 times of the minimum fluidizing velocity performance at bubbling fluidized-bed. Experiments have been performed on coal particle sizes of 0.3-1 mm, 1-1.18 mm and 1.18-2.8 mm, with operating temperatures being 100℃, 125℃ and 150℃, respectively. It is found that fluidization has a higher drying rate due to the heat transfer rate through air velocity. Hence, moisture content in lignite can be dried to a desired value with a time interval of 10 rain. The experiment through fluidized-bed reactor is expected to be useful for saving money and time.

Dependencies between price duration, volatility, volume and return on the Warsaw Stock Exchange

The successive changes of asset prices are the most visible manifestation of financial markets dynamics. There exist different views about factors generating these changes, but many researchers and practitioners agree that the most important among them is the impact of information flow. According to the market microstructure theories, it depends mainly on the behavior of informed and uniformed traders. In the paper, we investigate dependencies between the possible proxies of information process： price duration and corresponding to it volume change and return. Our main objective is to answer the question about the most important factor in the process of discovering information by uniformed traders. We apply a set of models for volatility, volume and duration data. Our analysis is performed for selected equities listed on the Warsaw Stock Exchange and uses tick-by-tick data. The obtained results show that the stock liquidity on this leading stock market in Central and Eastern Europe is the most important factor influencing the process of discovering information by uninformed traders.

Grammatical Consciousness-Raising Six steps to language learning

引用

基础教育外语教学研究 2007年第1期 35-39页

作者： Evelyn doman

Even in classes which stress oral practice, the explicit teaching of grammar still has a role to play. Evelyn doman explains why and presents some practical activities which integrate grammar teaching with communicative tasks in the grammatical consciousness-raising approach. Introduction The role of grammar in the foreign language classroom has been debated both long and hard. Theories about teaching grammar have covered all ranges of the spectrum, going from playing a major role to basically playing no role at all. Today, Communicative Language Teaching (CLT) is the forerunner in the TESL/TEFL community. Yet, even within the CLT framework, the controversy over the teaching of grammar continues. Many people still assert that grammar be given its place. I too am among these people, especially in EFL environments, such as in my previous teaching situations in South Korea.
