The effect of different winter cover crops on sorghum nutritional status and dr...

Growing winter cover crops has a great agroecological meaning, since it allow maintaining the residual inorganic N in the soil/plant system, thus avoiding leaching of N (Rodrigues et al., 2002). As winter cover crops, it can be grown diverse species (Jensen, 1992). If legume species were used, they can access atmospheric N through the establishment of a symbiotic relationship with N-fixing bacteria (Russelle, 2...

Ulcerações Dolorosas do Couro Cabeludo

A arterite temporal é um vasculite sistémica que afecta vasos de médio e grande calibre, em particular a artéria temporal. Os autores apresentam o caso de um doente observado por ulcerações extensas e dolorosas da região parieto-temporal direita, com cefaleia hemicraniana homolateral, amaurose fugaz e claudicação mandibular. As artérias temporais eram espessadas, dolorosas e sem pulso à palpação. Analiticamente...

Copper, nickel and zinc removal by peanut hulls: batch and column studies in mo...

The main goal of this research study was the removal of Cu(II), Ni(II) and Zn(II) from aqueous solutions using peanut hulls. This work was mainly focused on the following aspects: chemical characterization of the biosorbent, kinetic studies, study of the pH influence in mono-component systems, equilibrium isotherms and column studies, both in mono and tri-component systems, and with a real industrial effluent f...
