Objective. Curcumin, an active ingredient of turmeric, is proved to be a potential candidate controlling inflammation and bone resorption, but few reports are on the periodontitis. The purpose this study was evaluate whether intra-gastric administration curcumin could inhibit inflammation alveolar resorption in rats following ligature-induced experimental Materials method. Male Wistar were randomly divided into three groups: no ligature placement vehicle, curcumin. After animals sacrificed,...

This paper investigates a control strategy for wind farm with the direct-driven permanent-magnet synchronous generators (PMSG)-based turbines and fixed speed induction (FSIG)-based under unbalanced grid voltage condition. By controlling PMSG-based to inject negative-sequence current decreasing unbalance factor (VUF) at point of common coupling (PCC), double frequency oscillations in electromagnetic torque, active, reactive power output from FSIG-based can be suppressed. In this paper,...

This paper mainly proposes a capacity configuration strategy for hybrid wind farm with fixed-speed induction generator (FSIG)-based and permanent magnet synchronous (PMSG)-based farms during grid faults.

In response to the challenges of climate change and pursuit sustainable development strategies, optimization integrated energy system (IES) should incorporate low-carbon considerations. However, traditional models for IES primarily focus on source-load uncertainties, neglecting uncertainty associated with electricity indirect carbon emissions. To address this limitation, paper establishes a two-stage robust scheduling model that considers carbon-source-load multiple uncertainties. First,...
