A series of flow-through reactor experiments were undertaken to assess the potential effect of porewater advection and dissolved inorganic phosphorus (DIP) concentration on benthic DIP dynamics in permeable sediments collected from the Weizhou Island, northern South China Sea. The flux of DIP ranged from -0.13 to 0.05 mmol m-2 h-1, and the reversal...

This is the version of the toyCTM model used by Mailler et al. 2020, "Using an antidiffusive transport scheme in the vertical direction: a promising novelty for chemistry-transport model'. In this preliminary version, only zonal and vertical transport is fully functional. The chemistry solver is only preliminar. This model is written in Python and ...

The random-walk method is inherently simple and numerically stable. However, when used in hydro-environmental analyses, most of the existing random-walk methods ignore the influence of the non-uniform water depth and only consider the transport of inert materials, hence the inability of modelling biochemical reactions. In addition, they mainly exam...

Beginning with Turing's seminal work [1], decades of research have demonstrated the fundamental ability of biochemical networks to generate and sustain the formation of patterns. However, it is increasingly appreciated that biochemical networks also both shape and are shaped by physical and mechanical processes [2, 3, 4]. One such process is fluid ...

Current state-of-the-art models for estimating the pharmacokinetic parameters do not account for intervoxel movement of the contrast agent (CA). We introduce an optimal mass transport (OMT) formulation that naturally handles intervoxel CA movement and distinguishes between advective and diffusive flows. Ten patients with head and neck squamous cell...

Three representative earthen canals from urban, peri-urban, and rural-urban fringe of Sri Lanka were studied for a 2-year period against different seasons to capture insights important in ecological rehabilitation. Only the canal from rural-urban fringe showed a better water quality in wet season; elucidating, the impact of contaminated catchment r...

Respiratory syncytial virus can lead to serious lower respiratory infection (LRI), particularly in children and the elderly. LRI can cause longer infections, lingering respiratory problems, and higher incidence of hospitalization. In this paper, we use a simplified ordinary differential equation model of viral dynamics to study the role of transpor...

Three kinetic and equilibrium partitioning column experiments were performed to determine the rates and extent of desorption of five chlorinated hydrocarbons (1,2 cis-dichloroethylene (DCE), 1,2,2-trichloroethane (TCA), trichloroethylene (TCE), 1,2,3,4-tetrachloroethylene (PCA) and chlorobenzene) found in the contaminated sediments in a former brow...

A reaction–diffusion–advection equation with strong Allee effect growth rate is proposed to model a single species stream population in a unidirectional flow. Here random undirected movement of individuals in the environment is described by passive diffusion, and an advective term is used to describe the directed movement in a river caused by the f...
