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...

"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....
