Lime treatment is a widely applied technique in improving the workability and geotechnical properties of soil. The water retention property microstructure are highly related to hydro-mechanical behaviour unsaturated lime-treated In this study, evolution pore size distribution (PSD) along curves (during drying) were studied for soil, with emphasis put on curing time salinity effects. Two soil po...

Thirsty rats, previously trained to approach a white card and avoid an adjacent black card to obtain water, sustained discrete bilateral lesions to certain brainstem sites and were subsequently tested for retention. Those lesion placements producing retention deficits on this appetitively motivated visual discrimination problem closely corresponded with those producing retention deficits on ave...

Postoperative salt and water retention has been recognized for most of this century. Does it matter? Can or should it be avoided? These are still questions about which debate continues. Pringle, in 1905, observed reduced urine volumes and weight gain in postoperative patients [31]. Wilkinson studied 27 patients perioperatively and observed a decrease in urinary concentrations of sodium and chlo...

Fractal models of porous media are of interest in numerous scientific disciplines, including hydrology and soil science. This interest arises in part from the ability of these models to parsimoniously produce highly complex and richly structured geometries. Examination of the soil hydrology literature suggests that there are at least two different ways these models are being constructed. We rev...

[1] Measurements have been made of the effect of compaction on water retention, saturated hydraulic conductivity, and porosity of two English soils: North Wyke (NW) grassland clay topsoil and Broadbalk silty topsoil, fertilized inorganically (PKMg) or with farmyard manure (FYM). As expected, the FYM topsoil had greater porosity and greater water retention than PKMg topsoil, and the NW clay tops...

Pastures are an extensive land cover type; however, patterns in pasture greenhouse gas (GHG) exchange vary widely depending on climate and land management. Understanding this variation is important, as pastures may be a net GHG source or sink depending on these factors. We quantified carbon dioxide (CO2 ) and methane (CH4 ) fluxes from subtropical pastures in south Florida for three wet-dry sea...

Hypohydration occurs during cold-air exposure (CAE) through combined effects of reduced fluid intake and increased fluid losses. Because hypohydration is associated with reduced physical performance, strategies for maintaining hydration during CAE are important. Glycerol ingestion (GI) can induce hyperhydration in hot and temperate environments, resulting in greater fluid retention compared wit...

Chemical factors and physical constraints lead to coupled effects during particle transport in unsaturated porous media. Studies on unsaturated transport as typical for soils are currently scarce. In unsaturated porous media, particle mobility is determined by the existence of an air-water interface in addition to a solid-water interface. To this end, we measured breakthrough curves and retenti...
