Modeling and monitoring pathogen transport through vegetated filter strips
… filter strips (VFS) on surface and subsurface transport of fecal oviform (FC) surrogates for bacterial pathogens released from a surface - applied bovine/swine manure. The study included a field-based lysimeter equipped with multi-sensor moisture probes to monitor real-time water content …

South African transport : an energy model until the year 2000
The South African transport industry is analysed sector by sector in terms of the transport service provided and fuel energy requirements. Taking cognisance of energy availability, technical, social and economic criteria, estimates are formed to predict the likely transport pattern and associated …

Heating of solid matter via laser generated electrons
… heating. This occurred due to inhomogeneous transport in the fast electron beam, which is not present in a 1-material design, e.g. Al, where a monotonically decreasing current density is found. While the exact reasons were not fully elcuidated, various investigations were carried out to …

Vanadium uptake and transport in higher plants
The uptake and transport of vanadium in several higher plant species has been examined. Studies utilizing excised Hordeum roots have revealed the uptake patterns of two different ionic species of vanadium (V02+ and V03) to be similar. Both ionic forms exhibited a large extracellular component in …

Design of <i>In Vivo</i> Assays for Study of Transport, Biocompatibility and Toxicity of Nanoparticles
… of new <em>in vivo</em> assays for study of transport, biocompatibility and toxicity of nanoparticles (NPs) in zebrafish embryos. We synthesized and purified spherical silver (Ag) NPs with diameters, ranging from 12 to 95 nm, that are stable (non-aggregated) in egg-water media. We developed …

Land use change through market dynamics : a Microsimulation of land development, the bidding process, and location choices of households and firms
… is a pressing issue for planners, policymakers, transportation engineers, air quality modelers and others. Due to significant environmental, traffic and other impacts, the process of land development highlights a need for land use models with behavioral foundations. Such models seek to anticipate …

Spatial mismatch in Cape Town : business location and the impacts on workers
… further by an inefficient and expensive public transport service, upon which they are fully dependent. By way of the interviews with businesses from various industrial areas in Cape Town, this thesis shows that many owners and management do not place much importance on where their workers, in …

Hydrodynamic Controls on Sedimentology and Geomorphology of Marine-Carbonate Ramps: Insights from a Holocene Analogue, Northern Yucatán Shelf, Mexico
… the impacts of oceanographic processes on facies patterns of ramps remains uncertain. To explore these understudied processes, this study examines carbonate ramp dynamics by integrating in situ field measurements, remote sensing data, and hydrodynamic modeling of the Holocene northeastern Yucatán …

Investigation of the Colloidal Properties of Extracellular Vesicles from Yeast and Bacteria: Implications for Environmental Transport
<p>When considering the complex communication patterns between diverse collections of organisms in the environment, extracellular vesicles must be considered. Extracellular vesicles (EVs) are nanoscale, colloidal particles that are secreted by all cell types. While the functions of EVs have been …

Sediment Transport and Morphodynamics at an Estuary Mouth: a Study using Coupled Remote Sensing and Numerical Modelling
… image processing and, combined with the sediment transport module, the full model has been used to understand the relative importance of the driving forces at the region. The iterative application of the hydrodynamic model and the video images, with the modelled water levels used as input to the …

The application of historical data and computational methods for investigating causes of long-term morphological change in estuaries : a case study of the Mersey Estuary, UK
… Changes to tidal flow and related sediment transport patterns outside the estuary resulting from training wall construction are examined with regard to the stability of the estuary system. The results from computational hydrodynamic models representing the years 1906, 1936 and 1977 …
