In this paper we find the possible phase portraits and bifurcations for a general class of host-vector epidemic models with non-linear incidence function generalizing the Ross model

We discuss a multiscale Galerkin approximation scheme for a system of coupled quasilinear parabolic equations. These equations arise from the upscaling of a pore scale filtration combustion model under the assumptions of ...

Some new multidimensional Hardy-type inequalities involving arithmetic mean operators with general positive kernels are derived. Our approach is mainly to use a convexity argument and the results obtained improve some known ...

The pricing of seasonal and perishable crops such as tomatoes is of paramount concern to emerging economies. In this paper, we have formulated a model for the prices of tomatoes in the Ashanti Region of Ghana. We applied ...

This research was conducted at three fish smoking sites and three marketing centres in the Tema municipality, to compare the microbial load of smoked sardine (Sardinella aurita). Microbial load of smoked sardine were ...

In this study, we develop an advection-reaction-difusion system of partial diferential equations (PDEs) to describe interactions between tumor cells and extracellular matrix (ECM) at the macroscopic level. At the subcellular ...

This paper is devoted to the effects of surface roughness during hydrodynamic lubrication. In the numerical analysis a very fine mesh is needed to resolve the surface roughness, suggesting some type of averaging. A rigorous ...

In this paper we prove the homogenization of the Stokes e-quation by the method of multiple scale expansion. In particular the cell problems are clearly defined and an algorithm for obtaining the homogenized solution is ...

Resistance to thaumasite form of sulphate attack of blended cement mortars This study concerns the resistance against thaumasite form of sulphate attack on Portland cement reference with high volume ground granulated ...

We prove the existence of solutions for the neutral periodic integro-diferential equation with infnite delay x 0 ( t) = G(t, x(t), x(t − τ (t))) + d dt Q(t, x(t − τ (t))) + Z t −∞ Xn j=1 gj (t, s) x(t + T) ...
