With the widespread application of distributed generation (DG), their utilization rate is increasingly higher and higher in the power system. This paper analyzes the static and transient impact of large-scale DGs integrated with the distribution network load models on the power grid. Studies of...

An integrated, clean, facile and ecologically friendly approach of biodiesel production from Eruca Sativa Gars (ESG) vegetable oil focused on lab scaling up was reported in this study. Transesterification of ESG oil was heterogeneously catalyzed by Cs2.5H0.5PW12O40 heteropolyacid salt. The...

This paper explores the racial differences in politicians’ persistence in elections. Empirical data from California city council elections and a close election regression dis- continuity design (CERDD) suggest that losing an election causes 70% attrition in rerunning for office. After a loss,...

Hot workability of a forged beta gamma Ti-44Al-6Nb-1Mo-0.3 (B, Y, La, Ce) alloy was studied on a Gleeble-3800 thermal simulation machine under variable conditions. The flow stress and microstructural evolution were analyzed carefully after deformed at variable strain and holding time. All true...

Porous CoAl 3 intermetallic is a candidate material in the field of catalytic and filtration due to its high porosity, good thermostability and quasicrystal structure. However, its rapid and reliable preparation are still a challenge, and the high-temperature antioxidant mechanism need to be...

"Recent volatility in food prices and the growing disparity between prices at various stages of the marketing channel has generated much interest among agricultural producers, consumers, and policy makers. This study examines the effect of nonlinear threshold dynamics on asymmetric price...

In this paper, we propose a delayed predator–prey model with birth pulse and impulsive harvesting in a polluted environment. Existence conditions of the predator-extinction periodic solution are derived by developing the discrete dynamical system, which is determined by the stroboscopic map....
