Microbially mediated insoluble technetium (Tc) formation was studied using surface water covering paddy fields. Surface water samples were collected from three kinds of flooded paddy soils: andosol, gley soil, and gray lowland soil. Insoluble Tc (> 0.2 μm in size) was formed in all surface water samples and the amounts ranged from 48.7 ± 2.2% of total Tc (gley soil) to 88.5 ± 3.1% (gray lowland...

The effect of felling on stream nitrate, ammonium and soluble reactive phosphate (SRP) concentrations is examined for acidic and acid sensitive Sitka Spruce afforested catchments with podzolic and gley soils in mid-Wales. For the streams draining the felled podzolic areas, the concentrations of nitrate can be up to an order of magnitude higher than pre-fell values and post-fell concentrations c...

An investigation was carried out aiming at assessing the potential of vis-NIR reflectance spectroscopy, through comparison with the conventional X-ray powder diffraction (XRPD) technique, for the characterization of synthetic gleys, obtained in laboratory starting from Fe0 and Fe2+ under different conditions of initial pH (5.5, 7.0 and 8.5). XRPD analysis showed that in any case goethite formed...

This work aims to contribute the interpretation of soil colors; mainly identify pigments that generate greenish colors in hydromorphic conditions (gley colors) vertisols coastal plain Río de la Plata estuary. These are cold hues, generally (olive-gray), and occur poorly drained soils with prolonged water accumulation. For this purpose, samples Bssg horizons from estuary were analyzed using rout...

In June of 2005 the term hormone completed a life span of one century. The word that Ernest Henry Starling included in one of his four lectures to the Royal Society of Physicians of London, given in June 1905, definitively established the permanent representation in terminology for the products secreted by the endocrine glands. Various attempts by physicians and medical writers to replace the t...
