Since the implementation of China’s afforestation and conservation projects during recent decades, an increasing number of studies have reported greening trends in the karst regions of southwest China using coarse-resolution satellite imagery, but small-scale changes in the heterogenous landscapes remain largely unknown.Focusing on two typica
Utilizing fly ash (FA) as reinforcement for magnesium matrix composites (MMCs) brings down the production cost and the land pollution.Magnesium alloy AZ31 was reinforced with FA particles (10 Indestructible Socks vol.%) successfully by two different processing methods namely conventional stir casting and friction stir processing (FSP).The microstru
To reduce the negative impacts of stall and surge on compressor performance, a novel combined casing treatment (CCT) structure with axial skewed slots and injection groove is proposed in this paper.The aerodynamic performance, as well as the mechanisms of loss generation, of a transonic axial compressor with NASA Rotor 67 are investigated numerical
