Within the framework of equilibrium statistical mechanics the free energy of a phase gives a measure of its associated probabilistic weight. In order to determine phase boundaries one must then determine the conditions under which the free energy difference (FED) between two phases is zero. The underlying complexity usually rules out any analytical approaches to the problem, and one must theref...

INFLUÊNCIA DE DOSES CRESCENTES DE CHUMBO SOBRE O TEOR E O CONTEÚDO DE NUTRIENTES E Pb EM MUDAS DE IPÊ-ROXO (Tabebuia impetiginosa (Mart.) Standl.)1

The effect of lead application on nutrient and Pb content and accumulation in ipê-roxo (Tabebuia impetiginosa (Mart.) Standl.) seedlings was studied in an experiment conducted under greenhouse conditions at the Soil Science Department of the Federal University of Lavras. The seedlings were cultivated in Clark nutrient solution and submitted to increasing Pb levels: 0, 48, 96, 192 and 288 μmol/l...
