A new modification for the shear lag model is given and the expressions for the stiffness and yield Strength of short fiber metal matri×composite are derived. These expressions are then compared with our experimental data in a SiCw/Al-Li T6 composite and the published experimental data on different SiCw/Al T6 composites and also compared with the previous shear lag models and the other theoretical models.

AIM To compare the effects of liposomes andglyco-poly-L-lysine on liver targeted uptake andexpression of plasmid in rat liver.METHODS After binding with lipofectamine orgalactose-terminal glyco-poly-L-lysine,theplasmid could be expressed in eukaryotic cellswhen injected into Wistar rats by intravenousroute.At different time intervals after the injection,the distribution and expression of the plasmid inliver of rats were observed and compared using insitu hybridization and immunohistochemistry.RESULTS The expression of the plasmid bindingto liposomes or G-PLL could be markedly observed24 h later,and began to decrease one week later,but it still could be observed up to three weeks.Both liposomes and G-PLL could deliver theplasmid to the liver effectively,but the effect of thelatter was better than the former concerning thedistribution and expression of the plasmid targeteduptake in the liver.CONCLUSION G-PLL is better than liposome asthe targeted carrier for delivering exogenous genesto the liver.

The invention of microwave induced plasma during microwave heating makes it possible to confine plasma inside a crucible, in the pressure range of 1.33 Pa to 0.5 MPa, and above 900 degrees C. In this study, the step sintering of microwave heating and microwave plasma heating (SSMP) was proposed. In this process, microwave heating and plasma heating was ingeniously combined in one chamber, and vacuum was unnecessary for microwave induced plasma. In the first step, the microwave energy directly heated alumina ceramics to a given temperature, above which microwave will mainly ionize the gas and sustain a plasma. Then the plasma further heated alumina ceramics to the final temperature to finish sintering. Maintaining the advantages of microwave heating and plasma heating, this step sintering approach will overcome the limitation of both processes for processing ceramics, and it will be suitable for sintering all kinds of ceramics in principle.

AIM To compare the effects of intravenous routeand peritoneal route on liver targeted uptake andexpression of plasmid delivered by galactose-terminal glyco-poly-L-lysine(G-PLL).METHODS The plasmid pTM/MMP-1 which couldbe expressed in eukaryotic cells was bound to G-PLL,and was then transferred into Wistar rats byintravenous and intraperitoneal injection.Theexpression and distribution of the plasmid wereobserved at different time periods by in situhybridization and immunohistochemistry.RESULTS The plasmid could be expressedsignificantly within 24 h after being transferred invivo by both intravenous and intraperitonealroutes.One week later the expression began todecrease,and could still be observed three weekslater.Although both the intravenous andintraperitoneal route could target-specificallydeliver the plasmid to the liver,the effect of theformer was better as compared to that of the latter.CONCLUSION Intravenous route is better for livertargeted uptake and expression of G-PLL-boundplasmids than the peritoneal route.
