In the condition of connecting large scale doubly-fed induction generators (DFIGs) into weak grid, the closely coupled interactions between wind generators and power grid becomes more severe.Some new fault characteristics including voltage phase angle jump will emerge, which will influence the power quality of power system.However, there are very f
The micro-hydration degree plays a significant role in the strength of cement-sandy soil mixtures.The present study used cement-fiber-sandy soil mixtures in which the fiber was sourced from waste cotton/linen-blended fabric to investigate the impacts of different levels of fiber content on the hydration mechanisms and micromechanical performance.Ex
Organ transplantation has significantly changed the life expectancy of patients with advanced organ failure.The quality of life with transplanted organs and their impact on growth have become more critical for children as they have a much longer life expectancy and will be experiencing growth stages.Solid organ transplantation techniques, which wer
This paper focuses on the effects and mechanisms of rare earth and calcium on the flame retardancy of magnesium alloys.Rare earth elements form dodge challenger corsa exhaust dense composite oxide films on the surface of the melt, effectively inhibiting the progress of oxidation reactions and significantly increasing the ignition temperature of mag
