Application of a discrete element model to the analysis of granular soil recovery in an offshore tubular vibrocore
… to grow and become ever more relevant. Seabed soil sampling is crucial in deep-water engineering projects or geological studies where a detailed knowledge of the seabed geology is required. Deep-sea vibrocoring is a relatively new offshore sampling technique. The system consists of a vertical, …

Exploratory studies in the use of microwave radiation to assist the extraction of pollutants from various matrices.
… in the transfer of microwave energy to the soil structure. The first portion of water added, adsorbs on the soil surface very strongly and the microwave field cannot move these adsorbed water molecules. As the water content increases, excitation of the loosely bound outer layers facilitates …

Timber Harvesting and Site Preparation Effects on Soil Quality for Loblolly Pine Growing on the Lower Coastal Plain of South Carolina
… of nearly-level topography, poorly-drained soils, and high rainfall, which results in a perched water table in some soils that inundates the surface several times each year. Harvesting timber under wet site conditions often results in extensive soil compaction, rutting, soil displacement, …
