We consider a one-dimensional model biodegradation system consisting of two reaction–advection equations for nutrient and pollutant concentrations and a rate equation for biomass. The hydrodynamic dispersion is ignored. Under an explicit condition on the decay and growth rates of biomass, the system can be approximated by two component models by setting biomass kinetics to equilibrium. We deriv...

semi-regular locales are extensions of the classical semiregularspaces. we investigate the conditions such that semi-regularizationis a functor. we also investigate the conditions such that semi-regularizationis a reflection or coreflection.

Considering the increase in number of offshore oil production projects and for better understanding of plume dynamics in accidental underwater oil blowouts, a series of laboratory experiments in a square cross section open top basin were carried out to investigate the effect of changes in seawater stratification and water column stability on plume dynamics and peeling height.  Accordingly the o...

In this paper, we study the asymptotic profile of the steady state of a reactiondiffusion-advection model in ecology proposed in [13, 17]. The model describes the population dynamics of a single species experiencing a uni-directional flow. We show the existence of one or more internal transition layers and determine their locations. Such locations can be understood as the upstream invasion limi...
