Remote estimation of aquatic sediment density in the presence of scatter.
… of the first few meters of shallow marine sediment. Normal incidence reflections from a 16 kHz omnidirectional source are collected using a single hydrophone directly above the source. An empirical relationship is then used to estimate the sediment density from the normal incidence …

The characterisation of actinomycetes isolated from diverse South African sources, with emphasis on the genus Kribbella
… isolated from the leaves of indigenous plants, aquatic sediment and soil samples, using alternative isolation methods to select for actinomycetes belonging to the rarer genera. Thirty actinomycete strains belonging to the genera Gordonia, Kineococcus, Kribbella, Micromonospora, Nocardia and …

Detection and Quantification of Single-walled Carbon Nanotubes in Environmental and Biological Samples for Evaluation of Fate, Transport and Bioaccumulation
… affinity for HOCs. Upon release of SWCNT into aquatic environment, SWCNT have the potential to affect the distribution of organic contaminants by acting as strong sorbent. </p><p>A significant barrier to studying toxicity of SWCNT to animal models is the lack of in vivo techniques to track and …

Investigations on the Phenomena of Accumulation and Mobilization of Heavy Metals and Arsenic at the Sediment-Water Interface by Electrochemically Initiated Processes
… and municipal effluents are discharged. Aquatic sediments/environments are often polluted by heavy metals due to the temporal variations in anthropogenic input of contaminants via atmospheric deposition, catchment runoff, effluent inflow and dumping from industrial transportation, mining, …
