portrait is plotted for this system, the trajectory graph is a perfect ellipse that is symmetric about both axes. The phase portrait of a single degree of freedom non-impacting oscillator with x(0)=-0.01 m..., the dynamics of a single degree of freedom system limited to a barrier known as impact oscillator has been studied to gain a better understanding about what is softness effect of barrier on the energy......
3D Bioplotting of Gelatin/Alginate Scaffolds for Tissue Engineering:Influence of Crosslinking Degree and Pore Architecture on Physicochemical PropertiesTing Pan1,2,3,Wenjing Song1,2,3,Xiaodong... the scaffolds with different pore architectures by deposition of gelatin/alginate hydrogels layerby-layer. The scaffolds with different crosslinking degree were obtained by post-crosslinking methods.Their......
analysis and dynamics reduction experiment of pure ultra-fine ZnO, the experimental study on non-molten reduction and recovery and enrichment of zinc in dusts was carried out. The results show that zinc... of K, Cl and other elements, then the enrichment, called Zn-rich material, is obtained with the content of Zn up to 90%. At the same time, the dusts are reduced at the state of non-molten because......

the critical value, the growth velocity decreases with the increases of it. During a variety of degree of supercooling, the growth velocity is under control from thermal diffusion to kinetics. Under the control of thermal diffusion, the growth velocity increases with the increase of degree of supercooling and tip radius R decreases with the increase of temperature. Under the control of kinetics......
