In order to decrease the torque variation of a Savonius rotor and improve starting characteristics, new type rotor, which has three stages with 120-degree bucket phase shift between adjacent stages, been designed made. Wind tunnel tests make it clear that both static dynamic variations in one revolution this three-stage have greatly smoothed comparison an ordinary one-stage means improvement characteristics. The characteristics rotors guide vanes were also measured. increased coefficient on...
Abstract Building on conservation of resources theory, we construct a dual‐pathway approach which aims to reveal the mixed effects organizational resilience environmental, social and corporate governance (ESG) performance. Specifically, this paper argues that will both stimulate innovation input, enhancing ESG performance (positive pathway) promote strategic change, inhibiting (negative pathway). Meanwhile, indirect effect via input change is also moderated by industry concentration, are...
The bound states in the continuum (BICs) optical metasurfaces have latterly received prominent attention for their ultrahigh quality factors and promise that they hold realizing lowthreshold nanolasers, high-harmonic generation, slow-light devices.
