A bioengineered approach for sustainable crude oil pollution treatment via entrapment, dispersal and removal using Nano-CarboScavenger
… for a multipurpose oil sequestration and dispersion agent that is environmentally undisruptive. NCS distribution on crude oil contaminated water was found to combine both absorption and dispersion mechanisms to treat a maximum of 80% of the pollution, while NCS distribution on a petroleum …

Van Der Waals Interactions Based Rheological Analysis for Electrosterically Stabilized Nano-Sized Alpha Silicon Carbide-Lactobacillus Gg Dispersions
… rate, shear stress and viscosity that alter the dispersion mechanisms are also presented and discussed. The concurrence of the experimental analysis with the mathematical modeling is also presented. The rheological analysis in these systems for determining of the optimum amounts of dispersant, …

Ultra-Wideband Channel Modeling using Singularity Expansion Method
… models do not account for all the identified dispersion mechanisms namely the frequency dispersion, the resonant dispersion and the multipath dispersion. The objective of this research is to model resonant dispersion based on the Singularity Expansion Method (SEM) and provide guidelines for …

Flow Dynamics in Large River Basins: Self -Similar Network Structure and Scale Effects
… spatially invariant celerities and hydrodynamic dispersion coefficients. The presence of spatially varying celerities induces a dispersion effect, identified as kinematic dispersion, on the network travel time distribution. Its contribution to the total dispersion is comparable to that due to the …

Microbial instrumentation utilizing microfluidics
… are present in air yet little is known about the mechanisms that lead to their dispersion. We have elucidated one such dispersion mechanisms involving rain and soil bacteria. The experimental system replicates the process of raindrops impinging on soil surfaces that contain bacteria. It is …

Nano- to catchment-scale investigations of metal transport processes in mining-impacted river systems
… the variability of processes which control metal dispersion. This thesis aims to identify nano- to catchment-scale drivers of metal dispersion by: assessing the role of river catchment geomorphology in metal storage; quantifying metal sources across streamflow conditions; and investigating the …

Improved understanding and prediction of the hydrologic response of highly urbanized catchments through development of the Illinois urban hydrologic model (IUHM)
… been shown in natural watersheds that there are dispersion mechanisms that contribute to the impulse response function of the catchment: hydrodynamic dispersion, geomorphologic dispersion and hydrodynamic dispersion. We introduce a fourth dispersion mechanism, intra-state dispersion, that …

Modelling the transport of iron-based colloids in saturated porous media
… Colloid transport is governed by advection-dispersion mechanisms, filtration, particle-particle and particle-soil interactions. The latter result in dynamic deposition of the particles on (and release from) the grains of the porous medium. Hydrochemical parameters are known to greatly …
