The estimation of the hydrodynamic loading on cylindrical oil storage tank during earthquakes is of fundamental importance in the anti-seismic design. Interior semi-porous barriers are considered being effective to reduce the hydrodynamic response of the inner fluid and the loading on the tank wall. A reduced two-dimensional source distribution method and sub-region matching technique are developed for the prediction of three-dimensional hydrodynamic forces on oil storage tanks of arbitrary sections with interior semi-porous barriers of different configurations under earthquake excitations. Excellent agreement is observed between the present results and the corresponding analytical results for a circular cylindrical oil tank with a concentric interior semi-porous barrier, which shows the validity and effectiveness of the present method. A clear view of the influence of semi-porous barriers on the hydrodynamic response of tanks during earthquakes is obtained by the analyses of computational results, which may offer some guidance to the corresponding anti-seismic design for oil storage tanks and similar structures. The method is also extended to include the effects of the elastic vibrations of the tank.

The estimation of sloshing loading on liquid tanks is of fundamental importance due to the wide and important applications of liquid tanks in various engineering aspects. Analytical solutions for the sloshing loading on circular cylindrical liquid tanks with an interior concentric vertical thin semi-porous barrier under external excitations are presented. And the extensions of the solutions to the elastic vibrations and to the high frequency limit to count for the earthquake response are also included. A clear view on the influence of semi-porous barriers to the sloshing response of oscillating tanks is obtained by the analyses of systematic computational results. The present results may offer guidance to the corresponding design for liquid tanks of various applications and also a basis of comparison for the development of more sophisticated numerical methods for hydrodynamic and hydro-elastic analyses.

This paper studied the fractal characteristic of the interfacial shear surface of steel-Al solid to liquid bonding plate, and determined the relationship between fractal dimension and interfacial shear strength. The research results showed that the relationship between fractal dimension and interfacial shear strength could be described as y=26.2x+4.2 (where y was interfacial shear strength, x was fractal dimension) and when 08Al steel plate was coarsened by steel wire wheel which was made up with steel wires whose diameter were 1.4 similar to 1.6 mm, the optimum coarsening pattern of the steel plate surface could be got, the corresponding maximum interfacial shear surface fractal dimension of the bonding plate was 2.33, and the maximum interfacial shear strength of the bonding plate was 65.3 Mpa.

Objective: To analyze the effect of nuchal cords on perinatal features at delivery of term and postterm pregnancies. Methods: A total of 11,748 women with planned vaginal deliveries, including 9,574 term and 2,174 postterm deliveries, were analyzed for intrapartum events, clinical peripartum management, mode of delivery, and neonatal outcome. The presence of nuchal cords was diagnosed clinically at the time of delivery. Data were obtained from our perinatal database between 1995 and 2004 for retrospective analysis. Results: The incidence of nuchal cords in term and postterm deliveries was 33.7% and 35.1% , respectively. Multiple nuchal cords were present in 5.8% of term and 5.5% of postterm deliveries. Intrapartum signs of fetal compromise were increased in all groups, albeit not all reaching statistical significance in postterm deliveries. Meconium staining was significantly increased only in multiple nuchal cords of postterm deliveries (42.1% compared with 30.1% , p ps. Unfavorable neonatal blood gas values were significantly more frequent in all nuchal cord groups. Nevertheless, 5-minute Apgar scores less than 7 were not more common, and admission to neonatal unit was not required more frequently. Neonatal mean birth weight was significantly lower in all nuchal cord groups. Conclusion: Nuchal cords do not influence clinical management at delivery, and neonatal primary adaption is not imapired. Our data show that ultrasonographic nuchal cord assessment is not necessary at the time of admission for delivery.
