Double Hopf bifurcation of a diffusive predator–prey system with strong Allee effect and two delays

open access: yesNonlinear Analysis, 2021
In this paper, we consider a diffusive predator–prey system with strong Allee effect and two delays. First, we explore the stability region of the positive constant steady state by calculating the stability switching curves.

Nonhomogeneous porosity and thermal diffusivity effects on stability and instability of double-diffusive convection in a porous medium layer: Brinkman Model

open access: yesNonlinear Engineering, 2019
A model for double-diffusive convection in anisotropic and inhomogeneous porous media has been analysed. In particular, the effect of variable permeability and thermal diffusivity has been studied using the Brinkman model. Moreover, we analyse the effect

A theoretical model for double diffusive phenomena in cloudy convection [PDF]

open access: yesAnnales Geophysicae, 2003
Using classical rheological principles, a model is proposed to depict the molecular diffusion in a moist-saturated dissipative atmosphere: due to the saturation condition existing between water vapor and liquid water in the medium, the equations ...

Lysosome transport as a function of lysosome diameter. [PDF]

open access: yesPLoS ONE, 2014
Lysosomes are membrane-bound organelles responsible for the transport and degradation of intracellular and extracellular cargo. The intracellular motion of lysosomes is both diffusive and active, mediated by motor proteins moving lysosomes along ...

Double diffusive Darcy flow induced by a spherical source

open access: yesAin Shams Engineering Journal, 2015
A simple mathematical theory is proposed for the study of the free convective mass transfer flow induced by a spherical source in an unbounded porous medium assuming the validity of the Darcy flow model.

An axisymmetric non-hydrostatic model for double-diffusive water systems [PDF]

open access: yesGeoscientific Model Development, 2018
The three-dimensional (3-D) modelling of water systems involving double-diffusive processes is challenging due to the large computation times required to solve the flow and transport of constituents.
