The standard nonlinear ordinary differential equation (ODE) system for natural frequencies and critical load is given by use of ODE techniques, and then any indicated eigenvalue could be obtained directly from ODE solver by employing the so-called initial eigenfunction technique instead of the mode orthogonality condition. Numerical examples show that the present method is very effective and reliable.展开更多

Emphasis is laid on the discussion of searching for the singular points on the equilibrium path and of tracing the paths over the limit or bifurcation points. The method is applied to buckling analysis of thin shells. The pre-and post-buckling equilibrium paths and deflections can be obtained, which are illustrated in examples of buckling analysis of cylindrical and toroidal shells.展开更多

Hepatic ischemia and reperfusion injury model was established and whole cell patch-clamp techniques were used to investigate the effects of 2-APB on Isoc. The results showed that ischemia/reperfusion injuries could significantly reduce hepatocellular viability and further increase Isoc in hepatocytes and 2-APB (20, 40, 60, 80, 100 μmol/L) produced a concentration-dependent decrease of Isoc with IC 50 value of 64.63±10.56 μmol/L (n=8). It was concluded that ischemia/reperfusion injuries could reduce hepatocellular viability, probably through increased Isoc in hepatocytes and 2-APB had a protective effect on ischemia/reperfusion-induced liver injury, probably though inhibiting Isoc.展开更多

By assuming proper form of Fourier series with supplementary terms, which meet derivable conditions, for deflection and shear force functions, the basic differential equations with given boundary conditions can be transformed into a set of simple infinite algebraic equations. For common Winkler foundations, this set of equations can be solved directly and for tensionless Winkler foundations, it is a set of weak nonlinear algebraic equations, the solution of which can be obtained easily by using iterative procedures.展开更多

It can be said without exaggeration that, with an annual GDP growth rate of more than 8% throughout these 26 years, the material wealth created by the Chinese nation during this period almost surpasses the sum total of that created in the preceding century. This period marks also a time when the social structure of China underwent its most rapid transformation. Drastic changes took place in the spheres both of social production and styles of life with incredible rapidity. However, the reforms also touched off nu- merous social problems at the same time. One of the more striking problems is that of social polarization, leading to antagonism and conflicts among different strata that threaten social harmony and stability.展开更多

The modified coefficients are the exponent of A which is modified by the highly-viscous slurry medium, and the maximum density which is modified by the volume concentration of original debris flows with heterogenous grain size.展开更多

One of the important reasons is that the bioavailability of CsA varies largely among different patients but the use of CsA is not individualized. The human multidrug resistance gene-1 （MDR1） encodes P-glycoprotein （P-gp） that is responsible for resistance to foreign body and plays important roles in the absorption,展开更多

Characterization of microstructure revealed that the solution treated alloy consisted of α phase, α＇ phase and β phase, while besides these phases, the aged alloy also contained the precipitations of intermetallic Ti2Cu compound. The solution treated alloy showed better antibacterial performance with increasing the solution temperature. The Cu ions released from Ti-6AI-4V-5Cu alloy could effectively inhibit the formation of bacterial biofilm on the surface of alloy, and do not induce any cytotoxicity. The optimal heat treatment for Ti-6AI-4V-5Cu alloy was solution treated at 930 ℃, at which it could exhibit both promising antibacterial performance and no cvtotoxicity.展开更多
