DOI: 10.1002/aic.15568
Abstract: We show that most steady-state models of chemical reactors and reacting flows in which convection effects are dominant and diffusion/conduction is neglected in the flow direction but included in the transverse directions, may change from… read more here.

DOI: 10.1007/s40435-019-00508-x
Abstract: Parasites play vital role in dynamics of predator–prey interaction and regulating bio-diversity. We study qualitative behavior of two 3-dimensional discrete-time predator–prey-parasite models. Bifurcation analysis and chaos control are discussed by taking into account the study… read more here.
