2国内外泥石流预报警报系统研制概述——兼论铁路泥石流防灾警戒避难体制显示文摘对泥石流灾害和对待其它工程地质灾害一样,也应该采取以预防为主并与整治相结合的原则。为了保证山区城镇和工业的发展以及铁路、公路和航运的安全,在开展泥石流分布机理、成因和特性等研究的基础上,除注意发展工程整治(硬防治)的同时,还应特别注意开展软防治的研究工作,也就是开展多种形式的预报警报临测系统的研制,建立适合本部门、本地区的警戒避难体制,建立法规,以及发挥政府防汛部门、社会组织和个人的力量,通过各种媒介宣传和普及避难演习,将泥石流灾害遏制于摇篮之中,将灾害损失减少到最低程度。Railway construction institute under the academy of Railway Ministry 1989水土保持通报1989,9,3:5

5Integrin betal mediates hepatocellular carcinoma cells chemotaxis to laminin显示文摘BACKGROUND: Chemotaxis is an important step durin the invasion of carcinoma cells. And integrins are most im portant receptors mediating interaction between cells an extracellular matrix ( ECM). This study was designed t study integrin betal mediating chemotaxis of hepatocellula carcinoma (HCC) cells to laminin (LN). METHODS: A micropipette technique was adopted to in vestigate the effect of blockade of integrin betal on pseudo pod protrusion of HCC cells in response to LN stimulation Chemotactic pseudopod protrusion of a HCC cell was eva luated using a dual-pipette set-up, in which two pipette filled with LN solution were positioned in close contact wit the same cell, and pseudopod protrusion into each pipett was viewed dynamically and recorded with a tape recorder The lengths of pseudopods were measured and plotte against time to obtain a pseudopod growth curve. The in tegrin betal subunit on the surfaces of HCC cells were ana lyzed by flow cytometry. RESULTS: In dual pipette chemotaxis experiment, whe the two pipettes were filled with LN(50 μg/ml, 200 μg/ml) pseudopods extended from the HCC cell into each of th pipettes nearly symmetrically, ie, with nearly identica maximum pseudopod length and similar pseudopod growth curves. Upon addition of anti-CD29 (20 μg/ml) to one o the pipettes, pseudopod protrusion was blocked nearly completely while protrusion into the opposite pipette be came more evidently, with a larger maximum length. Ex pression of integrin betal was up to 95.78% to cells chosen in the experiment. CONCLUSION: Integrin betal subunit was an importan constituent receptor subunit for mediating chemotactic pseudopod protrusion of HCC cell to LN.Bian-Hong Fu, Ze-Zhi Wu and Cheng Dong Chongqing, China College of Bioengineering, Key Lab for Biomechanics and Tissue Engineering under the State Ministry of Education and College of Resources & Environmental Science , Chongqing University, Chongqing 400044, China Bioengineering Pro- gram, Pennsylvania State University, 205 Hallowell Building, University Park, Pennsylvania 16802-6804, USA 2004Hepatobiliary & Pancreatic Diseases International2004,3,4:4
6Protection of Linguistic Rights in China显示文摘The International Community has become increasingly keen on linguistic rights, regarding such rights as important human rights. The International Academy of Linguistic Law (IALL) has organized eight international conferences on the subject, with the question of linguistic rights featuring prominently in all of them. Back in 1996, the Hong Kong Polytechnic University played host to an internationalSU JINZHI director of the Social and Media Linguistics Division of the Institute of Linguistic Application under the Chinese Ministry of Education, and concurrently a Chinese member of the Preparatory Committee for the Ninth International Linguistic Law Conference. 2003The Journal of Human Rights2003,2,6:3
7Main Controls on Hydrocarbon Accumulation in the Paleozoic in Central Saudi Arabia显示文摘Saudi Arabia is renown for its rich oil and gas resources with the bulk of the reserves reservoired in the Mesozoic. However, the discovery of Paleozoic fields in the late 1980s has encouraged further exploration in the Paleozoic. This paper reviews the salient features of the Paleozoic petroleum geology in central Saudi Arabia and discusses the main factors controlling hydrocarbon accumulation in the Paleozoic. The Lower Silurian Qusaiba hot shale is the principal source rock for the hydrocarbons discovered in the Ordovician to Permian reservoirs. Of them, the Permo-Carboniferous Unayzah and Upper Ordovician Sarah Formations have the best exploration potential. The key factors controlling hydrocarbon accumulation in the Unayzah Formation are migration pathways and reservoir petrophysics. The key factors controlling hydrocarbon accumulation in the Sarah Formation are reservoir petrophysics and the development of structural traps.Bai Guoping (Key Laboratory for Hydrocarbon Accumulation under Ministry of Education, China University of Petroleum, Beijing 102249, China) 2007Petroleum Science2007,4,2:2

19EXPERIMENTAL STUDY ON DENSITY CURRENT WITH HYPERCONCENTRATION OF SEDIMENT显示文摘Based on data obtained from flume tests and reservoir observation, the characteristics of rheologic feature, flow pattern, conditions of formation, etc., of density current with hyperconcentration of sediment and resistance to the density current are studied. It is found that the flow pattern of the density current front is of turbulent and its subsequent part of lamilar. Formulae for computing water depth and resistance at the plunging points are deduced, and the calculated results conform well to observed data.CAO Ruxuan Senior engineer, Institute of Water Resources and Hydroelectric Engineering under the Shaanxi Institute of Mechanical Engineering 1993International Journal of Sediment Research1993,8,1:1
