HOPF BIFURCATION AND STABILITY IN A BEDDINGTON-DEANGELIS PREDATOR-PREY MODEL WITH STAGE STRUCTURE FOR PREDATOR AND TIME DELAY INCORPORATING PREY REFUGE

In this paper, we consider a Beddington-DeAngelis predator-prey system with stage structure for predator and time delay incorporating prey refuge.By analyzing the characteristic equations, we study the local stability of the equilibrium of the system.Using the delay here as a bifurcation parameter, the model undergoes a Hopf bifurcation at the coex

An electric arc is a common distribution grid 30x24x24 wall cabinet error, even more so with the use of electric vehicles and renewable energy sources that increase the likelihood of grid errors.Several control systems and strategies are under development to minimize electric-arc faults and to guarantee reliable grid performance.All the control str

Abstract Africa accounts for over one-third of the global burden of neglected tropical diseases (NTDs).Although continental chorulon hcg efforts have been made to combat these diseases, there still exists a significant gap in the fight, ranging from a lack of data to multisectoral participation and, most critically, health inequity.Here, we assess
