The calcite saturation status of soil-water systems in semiarid regions was reexantined taking into consideration organic ligand alkalinity and Ca-organic complexation. These factors have been forwarded as the reason for earlier reports of calcite Supersaturation in soilwater systems. We examined groundwaters beneath irrigated lands, soil-water suspensions in the laboratory using four soils and...

Abstract. Motivated by recent discussions concerning differences of convective dynamics in polluted and pristine environments, the so-called invigoration particular, this paper provides an analysis factors affecting updraft buoyancy, such as in-cloud supersaturation, condensate precipitation loading, entrainment. We use deep period from simulations daytime convection development over land discu...

The fundamental behavior of sodium sulfate crystallization and induced decay in concrete and other building materials is still poorly understood, resulting in some misinterpretation and controversy. We experimentally show that under real world conditions, both thenardite (Na2SO4) and mirabilite (Na2SO4 10H2O) precipitate directly from a saturated sodium sulfate solution at room temperature (20°...
