9Purge and trap method to determine alpha factors of VOC liquid-phase mass transfer coefficients显示文摘A theoretical approach and laboratory practice of determining the alpha factors of volatile organic compound (VOC) liquid-phase mass transfer coefficients are present in this study. Using Purge & Trap Concentrator, VOC spiked water samples are purged by high-purity nitrogen in the laboratory, the VOC liquid-phase mass transfer rate constants under the laboratory conditions are then obtained by observing the variation of VOCs purged out of the water with the purge time. The alpha factors of VOC liquid-phase mass transfer coefficients are calculated as the ratios of the liquid-phase mass transfer rate constants in real water samples to their counterparts in pure water under the same experimental conditions. This direct and fast approach is easy to control in the laboratory, and would benefit mutual comparison among researchers, so might be useful for the study of VOC mass transfer across the liquid-gas interface.S.C.Lee L.Y.Chan C.Y.Chan 2000Chinese Science Bulletin2000,45,S1:1

13胶原蛋白-聚乙烯醇复合再生蛋白纤维的研究显示文摘以从含铬革屑中提取的胶原蛋白为原料,配制分子量不小于100,000Da,且铬含量低于百万分之5的胶原蛋白纺丝原液,采用湿法纺丝制得再生蛋白纤维。为增强纤维的稳定性和力学性能,在胶原蛋白原液中加入戊二醛含量不高于0.3%的聚乙烯醇溶液。通过湿法纺丝实验,发现当原液的粘度高于1000cps时,可获得优良的可纺性。选择以含量不低于40%的硫酸钠和1M的硼酸组成的混合液为凝固浴,温度30℃~35℃的条件下,纺丝原液的成纤性最好。最后,以15%的硫酸钠、0.5%的戊二醛以及0.25%的甲醛溶液为交联剂处理再生纤维以增强抗水性。再生蛋白纤维的线密度为1.3g/cm^2,抗张强度为(1.32~2.0)g/d,伸长率为29%~38%。E.C.Shin S.C.Lee W.J.Kim 贾淑平(编译) 2008北京皮革(中外皮革信息版)(中)2008,,7:0
14CHOP THER APY INDUCED MITOCHONDRIAL REDOX STATE ALTERATION IN NON-HODGKIN'S LYMPHOMA XENOGRAFTS显示文摘We are interested in investigating whether cancer therapy may alter the mitochondrial redox state in cancer cells to inhibit their growth and survival.The redox state can be imaged by the redox scanner that collects the fuorescence signals from both the oxidized-fAavoproteins(Fp)and the reduced form of nicotinamide adenine dinucleotide(NADH)in snap frozen tissues and has been previously employed to study tumor aggressiveness and treatment responses.Here,with the redox scanner we investigated the effects of chemotherapy on mouse xenografts of a human diffuse large B.cell lymphoma cell line(DLCL2).The mice were treated with CHOP therapy,i.e,cyclophosphamide(C)+hydroxydoxorubicin(H)+Oncovin(O)+prednisone(P)with CHO administration on day 1 and prednisone administration on days 1-5.The Fp content of the treated group was significantly decreased(p=0.033)on day 5,and the mitochondrial redox state of the treated group was slightly more reduced than that of the control group(p=0.048).The decrease of the Fp heterogeneity(measured by the mean st andard deviation)had a border-line statistical significance(p=0.071).The result suggests that the mitochondrial metabolism of lymphoma cells was slightly suppressed and the lymphomas became less aggressive after the CHOP therapy.H.N.XU H.ZHAO T.A.MIR S.C.LEE M.FENG R.CHOE J.D.GLICKSON L.Z.LI 2013Journal of Innovative Optical Health Sciences2013,6,2:0
15同进承受梁顶、梁底荷载深梁的抗剪强度显示文摘试验研究的是钢筋混凝土深梁同时承受梁顶梁底荷载时的作用,针对这类梁的预估的抗剪强度提出了可采用的方法。其它研究者以前发表的实验结果用来和理论上的论断做比较和验证之用。说明了实验和理论二者非常吻合,现存的定理和建议方法被认为是很有影响的。张建文 S.C.Lee 1997国外建材科技1997,18,2:0
