1EFFECTS OF SPECIFIED BLANK SIZE ON BODY WRINKLING DURING HYDRODYNAMIC DEEP DRAWING OF TAPERED RECTANGULAR BOX显示文摘In this paper, the forming features of tapered rectangular box during hydrodynamic deep drawing are studied by means of FEM.The effect rules of square blank corner corner amount on body wrinkling are recognized and corresponding methods are discussed. At last, the results of FEM are verified by experi- ment.L. H. Lang, D. C. Kang, S. H. Zhang, Z. R. Wang, S. J. Yuan, K. B. Nielsen and J.

2Carbon and Strontium Isotopes of Late Palaeozoic Marine Carbonates in the Upper Yangtze Platform,Southwest China显示文摘238 marine carbonate samples were collected from seven sedimentary sections ofthe entire late Palaeozoic (Permian, Carboniferous and Devonian) in the Upper Yangtze Plat-form, southwest China. Based on the absence of cathodoluminescence and very low Mn (gener-ally<50 ppm) contents of the samples, it is thought that they contain information on the orig-inal sea water geochemistry. The results of isotopic analyses of these samples are presented interms of δ13C and 87Sr/86Sr ratios versus geological time. The strontium data, consistent withother similar data based on samples from North America, Europe, Africa and other areas inAsia, support the notion of a global consistency in strontium isotope composition of marinecarbonates. The strontium data exhibit three intervals of relatively low 87Sr/86Sr ratios in thelate Middle Devonian to early Late Devonian, Early Carboniferous and Early Permian, corre-sponding to global eustatic high sea level stands. The lowest 87Sr/86Sr ratio recorded in theLate Permian was probably caused by substantial basalt eruptions in the Upper Yangtze Plat-form at the time. Three corresponding periods of relatively high δ13C values at roughly the samethe intervals were caused by a relatively high rate of accumulation of organic carbon duringsea level rises at these times. The deposition of coal was probably responsible for the increaseof sea water δ13C at other times. The δ13C values drop dramatically near theDevonian/Carboniferous, Carboniferous/Permian and Permian/Triassic boundaries, con-sistent with other similar data, which further support the notion that geological time boundariesare associated with mass extinction and subsequent rejuvenation.Huang Sijing and Zhou Shaohua State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation,Chengdu University of Technology, Chengdu, 610059, Sichuan, China Geological Institute, University of Copenhagen, Oster Voldgade 10,DK-1350 Copenhagen K,Denmark 1997Acta Geologica Sinica(English Edition)1997,71,3:11
3Neutron-induced apoptosis of HR8348 cells in vitro显示文摘INTRODUCTIONTo date ,the major therapy for rectal carcinoma is extensive abdomino-perineal resection[1]. Unfortunately ,after resection of rectal carcinoma ,many patients still die of blood-borne metastases ,usually in the liver or lungs ,or local prlvic recurrence[2,3],which is the major cause of morbidity and mortality in patients with rectal carcinoma .Pre-or postoperative radiotherapy can reduce the incidence of local rdcurrence[4-7].Li Ping Wang~1 Ke Liang~2 Yu Shen~2 Wei Bo Yin~2 G.Hans~3 Yan Jun Zeng~1 ~1Biomechanics & Medical Information Institute,Beijing Polytechnic University,Beijng 100022,China ~2Department of Gastrointestinal Surgery,Aalborg University,Denmark ~3Cancer Institute (Hospital),Chinese Academy of Medical Sciences,Peking Union Medical College,Beijing 100021,ChinaLi Ping Wang graduated from Beijing Polytechnic University in 2000,major in tumor radiotherapy,having 3 papers published. 2001World Journal of Gastroenterology2001,7,3:5
4Sequencing,annotation and comparative analysis of nine BACs of the giant panda(Ailuropoda melanoleuca)显示文摘A 10-fold BAC library for the giant panda was constructed and nine BACs were selected to generate finish sequences.These BACs could be used as a validation resource for the de novo assembly accuracy of the whole genome shotgun sequencing reads of the giant panda newly generated by Illumina GA sequencing technology.Complete Sanger sequencing,assembly,annotation and comparative analysis were carried out on the selected BACs of a joint length 878 kb.Homologue search and de novo prediction methods were used to annotate genes and repeats.Twelve protein coding genes were predicted,seven of which could be functionally annotated.The seven genes have an average gene size of about 41 kb,an average coding size of about 1.2 kb and an average exon number of 6 per gene.Besides,seven tRNA genes were found.About 27 percent of the BAC sequence is composed of repeats.A phylogenetic tree was constructed using a neighbor-join algorithm across five species,including the giant panda,human,dog,cat and mouse,which reconfirms dog as the most closely related species to the giant panda.Our results provide detailed sequence and structure information for new genes and repeats of the giant panda,which will be helpful for further studies about the giant panda.ZHENG Yang1,2,3,CAI Jing4,LI JianWen3,6,LI Bo3,LIN RunMao3,TIAN Feng3,WANG XiaoLing3 & WANG Jun3,5 1Beijing Institute of Genomics,Chinese Academy of Sciences(CAS),Beijing 100029,China 2College of Life Science,Graduate University of Chinese Academy of Sciences,Beijing 100049,China 3Beijing Genomics Institute at Shenzhen,Shenzhen 518083,China 4CAS-Max Planck Junior Research Group on Evolutionary Genomics,State Key Laboratory of Genetic Resources and Evolution,Kunming Institute of Zoology,Chinese Academy of Sciences(CAS),Kunming 650223,China 5Department of Biology,University of Copenhagen,Copenhagen DK-2200,Denmark 6School of Biological Science and Engineering,South China University of Technology,Guangzhou 510006,China 2010Science China(Life Sciences)2010,53,1:5
5A brief introduction to recent applications of several sediment-analysis techniques in palaeolimnological studies-dry bulk density and water content, mineral magnetism, carbonate content, and content of total organic carbon,nitrogen content and carbon/ni显示文摘Determination of dry bulk density and water content measurement of magnetic susceptibility (x) and saturation isothermal remanent magnetization (SIRM), determination of carbonate content, and determination of total organic carbon (TOC) content nitrogen content (N%) and carbon/nitrogen (C/N) ratio are some of the techniques which have been widely applied to lacustrine-sediment analyses. The techniques,complemented by others, are usually useful for revealing characteristics of lacustrine-sediments and thus for postulating hydrological regimes in the lake and environmental conditions and human activity around it in palaeolimnological studies. A very brief review is presented on recent applications of these techniques in palaeolimnological work with English literatures published mainly since 1985 and focus given on interpretations of results of these analyses related to palaeoenvironmental reconstructions. Low dry bulk density and high water content often imply relatively warm and wet conditions. High X and SIRM are usually resulted from reduced dilutions in the lake and intensified erosions on its catchment. both of which can be in turn attributed to environmental changes. While variations in patterns of X and SIRM may give further insight on mineral magnetism and thus implications on environmental conditions. Increased carbonate content seems likely to associate to warm and dry conditions.Increased TOC content is virtually used as one of indicators of warm and wet conditions and variations in C/N ratio may hint variations in relative contributions of different sources, aquatic and terrestrial, to the total organic matter in lake sediments and hence to lake-level fluctuations and climate changes.WANG Hong-ya (Dept. of Urban and Environmental Sciences, Peking University, Beijing 100871, China Geophysical Laboratory, Dot. of Earth Sciences, University of Aarhus, Finlandsgade 8.
