1焦炭特性及其在高炉下部的变化过程显示文摘气化、石墨化和溶解是影响焦炭从高炉软熔带至炉缸间行为的三个主要过程。过去几年在一些专题项目中对这些过程进行了研究。简要叙述并讨论了这些过程的相互作用及其与焦炭特性的关系。对焦炭的气化反应进行了实验室测试研究,用以评价高炉条件下焦炭的特性。用高炉条件下的气化测试装置测试了几种焦炭试样,考查的质量指标包括反应性、结构变化和强度等。用实际尺寸的焦炭块对块状焦炭试样的高温行为进行了评估,将不同种类的焦炭试样加热到2 000℃,以鉴别其在高温下的行为。高温下焦炭将发生石墨化,对高温反应后的强度进行了评定,并作了显微观察,发现了一些现象和组织结构的变化。焦炭与液态渣铁相互作用的研究结果对焦炭在高炉下部的行为有了更好的理解。通过试验研究了焦炭抗液态铁水溶解的性能,对入炉前的焦炭和经高温反应的焦炭分别进行了试验。分析讨论了焦炭的抗气化、抗石墨化和抗铁水溶解性能与其结构、化学成分和强度的关系。B van der Velden C J Atkinson T Bakker J R H Stuurwold G J Tijhuis 徐万仁 2014世界钢铁2014,,2:11
2Investigation of operational parameters for an industrial CFB combustor of coal,biomass and sludge显示文摘The combustion of coal and/or biomass (sludge, wood waste, RDF, etc.) in a circulating fluidized bed has been a commercial topper for over20 years, and references to principles and applications are numerous and widespread although few data are presented concerning the operation oflarge scale CFB-units. The authors studied the CFB-combustion at UPM-Kymmene (Ayr), a major paper mill relying for its steam production uponthe combustion of coal (80-85%), wood bark (5-10%) and wastewater treatment sludge (5-10%). The maximum capacity of the CFB is 58 MWth.A complete diagnostic of the operation was made, and additional tests were performed to assess the operating mode. The plant schematics,relevant dimensions and process data are given. To assess the operation of the UPM-CFB, it is important to review essential design parameters andprinciples of CFB combustors, which will be discussed in detail to include required data, heat balance and flowrates, operating versus transportvelocity, kinetics and conversion (including the possible effect of the Bouduard reaction if carbon is present).Since the residence time in the riser and the cyclone efficiency determine the burnout of circulating fuel-particles, the UPM-CFB was subjectedto a stimulus response technique using nickel oxide as tracer. Results illustrate the efficiency of the cyclone separation and the number of recycleloops for particles of a given size. Results will also be used to assess the cyclone operation and efficiency and to comment upon expected andmeasured carbon conversion.Manon Van de Velden Jan Baeyens Bill Dougan Alan McMurdo 2007China Particuology2007,5,4:9
3慢性牙周炎患者的龈下微生物与吸烟状况显示文摘目的 评价慢性牙周炎患者的吸烟状况与龈下牙周致病微生物的百分比。方法 112例慢性牙周炎患者 ,根据吸烟状况分为 :①重度吸烟组 >10支 /天 (n =32 ) ;②轻度吸烟组≤ 10支 /天 (n =18) ;③戒烟者组 (n =2 4 ) ;④非吸烟组 (n =38)。观察者口内每个象限 ,选取探诊最深的 1或 2个位点 ,纸捻法取龈下菌斑 ,厌氧培养 ;并测量该位点的探诊深度 (ProbeDepth ,PD)、附着丧失 (AttachmentLoss,AL)和探诊后出血 (Bleedingofprobe ,BOP)。结果 ①取样位点临床指标的均值为PD :6 .3mm、AL :6 .5mm及BOP :89% ,各组间无显著性差异。②组间菌落形成单位和龈下微生物伴放线放线杆菌 (Actinobacillusactinomycetemcomitans,A .a)、牙龈卟啉单胞菌 (Porphyromanasgingivalis,P .g)、中间普氏菌 (Prevotellaintermedia ,P .i)、核梭杆菌 (Fusobacteriumnucleatum ,F .n)和微消化球菌(Peptostreptococcusmicros,P .m)的百分比均无差异。③方差分析显示仅轻度吸烟组福赛类杆菌 (Bacteroidesforsythus,B .f)的百分比略高于其它组 (P <0 .0 4 )。结论 慢性牙周炎患者 ,探诊深度和附着丧失相似的位点 ,吸烟组、戒烟组和非吸烟组的龈下牙周致病微生物百分比 (B .f除外 )无显著差异。徐莉 B.G.Loos A.J.van Winkelhoff U.vander Velden 2002现代口腔医学杂志2002,16,3:6
4A unique hormonal recognition feature of the human glucagon-like peptide-2 receptor显示文摘Glucagon-like peptides(GLP-1 and GLP-2)are two proglucagon-derived intestinal hormones that mediate distinct physiological functions through two related receptors(GLP-1R and GLP-2R)which are important drug targets for metabolic disorders and Crohn's disease,respectively.Despite great progress in GLP-1 R structure determination,our understanding on the differences of peptide binding and signal transduction between these two receptors remains elusive.Here we report the electron microscopy structure of the human GLP-2R in complex with GLP-2 and a Gs heterotrimer.To accommodate GLP-2 rather than GLP-1,GLP-2R fine-tunes the conformations of the extracellular parts of transmembrane helices(TMs)1,5,7 and extracellular loop 1(ECL1).In contrast to GLP-1,the N-terminal histidine of GLP-2 penetrates into the receptor core with a unique orientation.The middle region of GLP-2 engages with TM1 and TM7 more extensively than with ECL2,and the GLP-2 C-terminus closely attaches to ECL1,which is the most protruded among 9 class B G protein-coupled receptors(GPCRs).Functional studies revealed that the above three segments of GLP-2 are essential for GLP-2 recognition and receptor activation,especially the middle region.These results provide new insights into the molecular basis of ligand specificity in class B GPCRs and may facilitate the development of more specific therapeutics.Wen Sun Li-Nan Chen Qingtong Zhou Li-Hua Zhao Dehua Yang Huibing Zhang Zhaotong Cong Dan-Dan Shen Fenghui Zhao Fulai Zhou Xiaoqing Cai Yan Chen Yan Zhou Sarina Gadgaard Wijnand JCvan der Velden Suwen Zhao Yi Jiang Mette MRosenkilde HEric Xu Yan Zhang Ming-Wei Wang 2020Cell Research2020,30,12:4

6eDoc Server项目:建设马普学会的机构知识库显示文摘1引言 马普学会是一个多学科的研究机构,该学会制定了一项战略,旨在使Internet成为变革科学和学术交流、增强对所有与自身研究相关的信息资源的获取的重要渠道,eDoc Server(马普学会电子文档服务器)项目即是这一战略决策的一部分。马普学会将开放获取看作是实现上述战略的一个关键的先决条件,因此在2003年10月22目发起召开了“对科学与人文知识的开放获取”柏林会议,并在会议上联合德国和法国所有主要的研究机构和文化遗产继承单位、以及其他国家的部分科研机构和研究人员签署了“柏林宣言”。德国的主要研究机构正式接受开放获取原则是经过马普学会内部的充分讨论、及其与德国其它关键机构充分讨论后的决定。Gerhard Beier Theresa Velden 常唯编(译) 2005图书情报工作动态2005,,12:3

9猪血浆蛋白可提高仔猪的采食量,改善其健康状况显示文摘自2005年9月起,欧盟再次准许猪血浆作为猪和家禽的饲料原料。这一许可完全恰巧和2006年1月1日起禁止在动物饲料中使用抗生素生长促进剂(Antimicrobial Growth Promoters,AGPs)相对应,因为血浆也能改善仔猪的生长性能和健康状况,又不会产生抗生素耐药性。陶莉 Geert Van der Velden 2012国外畜牧学(猪与禽)2012,,10:2
