In this section, the dynamic propagation behavior Super Fruits of a penny-shaped interface crack in piezoelectric bimaterials is analyzed.The objective of this paper is to use the boundary conditions of the penny-shaped interface crack to study the dynamic propagation of the crack under the action of load, so as to provide some valuable implication
Abstract Background Chronic obstructive pulmonary disease (COPD) is a chronic lung inflammatory disease which has a close relationship with aging.Genome-wide analysis reveals that DNA methylation markers vary obviously with age.DNA methylation variations in peripheral blood have the potential to be biomarkers for COPD.However, the specific DNA meth
In comparison with the traditional way of trading, the Internet business companies have greater growth potential.This is true for as long as they are able to recognize and expand efficient marketing activities within the ever changing boundaries of ecommerce.For Internet shops this implies the ability to design an attractive purchase conditions and
In this paper a novel multilevel boost DC to DC converter with H-Bridge inverter circuit for single DC source is proposed.The proposed scheme has two stages: the first one is a multilevel boost converter which gives a multilevel dc output for a single dc source and the second level is a H-Bridge converter which converts multilevel DC to multilevel
In Seasonal X-mas this work, gallium-doped zinc oxide was deposited with a Radio Frequency Magnetron sputtering method on test platforms.The NO2 sensing properties of the resulting devices were studied.The sensing properties of ZnO:Ga thin films were successfully stabilized through annealing in dry air, and then improved by either a thinning of the
