A deterministic compartmental model for the transmission dynamics of onchocerciasis with nonlinear incidence functions in two interacting populations is studied. The qualitatively analyzed to investigate its local asymptotic behavior respect disease-free and endemic equilibria. It shown, using Routh-Hurwitz criteria, that equilibrium locally asymptotically stable when associated basic reproduct...

While there is almost unanimous consent among scientists that climate change real and has detrimental consequences, a sizable number of people who are skeptical towards these propositions not worried by change. In an attempt to understand the basis skepticism, we look at role intolerance, culturally transmitted attitude effect with certain characteristics be respected. The theoretical link from...
