一、引言在生物膜的研究中,人红细胞膜是最常用的材料之一.由于它与医学的密切关系,因此这方面的研究一直很活跃.近十年来,对其组成和结构已有了相当多的了解.在文献[3]中,我们报导了一种研究红细胞膜动态结构的方法——“渗透休克”法,通过测定低渗下的红细胞溶血速率,了解到溶血速率和细胞膜流动性有着一定的关系,但溶血速率的温度效应却显示出和膜流动性参数之间不一样的结果,表明这种溶血速率和红细胞的其他结构因子有关系.本文进一步研究了ph对红细胞溶血速率的影响,认为血红蛋白和红细胞膜的结合可能属于这种结构因子.

Earthquake Engineering and Engineering Vibration 2002年第1期1卷 145-151页

作者： Weimin Dong Risk Management Solutions,Inc.USA ph.D and Visiting Professor of Institute of Engineering Mechanics Risk Management Solutions Inc. USA

Internationally earthquake insurance,like all other insurance (fire,auto),adopted actuarial approach in the past, which is,based on historical loss experience to determine insurance *** to the fact that earthquake is a rare event with severe consequence,irrational determination of premium rate and lack of understanding scale of potential loss led to many insurance companies insolvent after Northridge earthquake in 1994. Along with recent advances in earth science,computer science and engineering,computerized loss estimation methodologies based on first principles have been developed to the point that losses from destructive earthquakes can be quantified with reasonable accuracy using scientific modeling techniques. This paper intends to introduce how engineering models can assist to quantify earthquake risk and how insurance industry can use this information to manage their risk in the United States and abroad.

Graphite/TiO2 composite particles were obtained by sol-gel technique in this paper. The structure and characteristic of the composite particles are analyzed by XRD, SEM and TG-DTA. The electrorheological properties of the ER fluid containing the particles were measured by a Couette-type rheometer under shear rates of 1-136 s-1 and AC electric fields of 0-3 kV/mm. The experimental results show that the leaking current density of the ER fluid is higher than that of pure titanium dioxide particles dispersed in damping oil. The shear yield stress of the ER fluid increases with increasing electric field and exhibits a typical Bingham flow behavior. The suspension demonstrates an excellent ER performance (τ/τo=1200) compared with conventional ER fluids (τ/τ0 ≤500). The sedimentation of the ER fluid is improved obviously due to the coating effect of the particles.

AIM To recognize the characteristic findings of micrQliver cancer (MLC) and to evaluate the effect of CT arterial portography (CTAP) and CT hepatic arteriography (CTHA) in diagnosis of MLC. METHODS Between April 1996 to December 1998, CTAP and CTHA were performed in 12patients with MLC, which were not detect ed byconventional CT examinations. After CTHA, 3 mL-- 5 mL mixture of lipiodol, doxorubic in andmitomycin C were injected into hepatic arterythrough the catheter, and then followed up by CTthree or four weeks later (Lipiodol CT LP-CT).RESULTS A total of 22 micro--tumors (0 .2 cm 0.6 cm in diameter ) were detected in 12patients, which manifested as small perfusiondefects in CTAP and small round enhancement inCTHA. The rate of detectability of CTAP andCTHA was 68.2% (15/ 22) and 77.3% (17/ 22)respectively, and the rate of the simultaneoususe of both procedures reached 86. 4% (19/ 22 ).All micro--tumors were demonstrated as punctatelipiodol deposit fool in LP--CT. After LP--CT, theelevated serum level of Q-fetoprotein (AFP)dropped to the normal level in all *** The CTAP and CTHA are the mostsensitive imaging methods for detecting microIiver cancer. Confirmed by the change of theelevated serum AFP level and lipiodol depositfool in LP-CT, small perfusion defects in CTAPand punctate enhancement in CTHA may suggestmicro--liver cancer.

Vermicular graphite cast iron （VG iron for short in the following sections） is a type of cast iron in which the graphite is intermediate in shape between flake and spheroidal. Compared with the normal flake graphite in grey iron, the graphite in VG iron is shorter and thicker and shows a curved, more rounded shape. Because its outer contour is exactly like a worm, hence it is called vermicular graphite. Since the compactness of the graphite （i.e. the ratio of width/length, d/t） in VG iron is far higher than that in grey iron, it is also called compacted graphite. Considering both names, this type of graphite is often referred to as C/V graphite internationally.

With a record number of blockbuster drugs losing patent protection in recent years, major U.S. based multinational drug makers are finding ways to cut cost in order to keep their profit margin in the face of fierce generic competition. On the other hand, generic drug makers are looking for quality, yet inexpensive API/intermediate outsourcing suppliers in order to be profitable in a highly competitive industry. This has created an excellent opportunity for Chinese pharmaceutical companies to become active-pharmaceutical-ingredient (API, or drug substance) and/or pharmaceutical intermediate suppliers for the lucrative U.S.
