1. Sustained swimming improves fish dietary nutrient assimilation efficiency and body composition of juvenile Brycon amazonicus
ABSTRACT Sustained swimming (SS) usually promotes beneficial effects in growth and feed conversion of fishes. Although feed efficiency is improves at moderate water velocity, more information is required to determine the contributions of this factor on growth and body composition. Body composition and efficiency responses to the use of nutrients were determi

2. Utilization and fate of phosphorus of different sources applied to cohesive soil of Amazonian periphery
ABSTRACT In the Amazonian region, P is often a primary factor limiting sustainable agrosystems. We compared the efficiencies of local aluminous phosphate (ALP) and single superphosphate (SSP) under a cover of leguminous residues to determine the fate of P sources in an Amazonian soil with hardsetting characteristics. The experiment followed a randomized bloc

5. Avaliação eletroquímica do desempenho de células termogalvânicas empregando líquidos iônicos como meio eletrolítico e alumínio como eletrodos
Thermogalvanic cells are thermoconverter electrochemical devices where two electrodes, not necessarily chemically identical or reversible, are held at different temperatures. The temperature difference between the electrodes creates a potential difference that can be used to drive current to an external circuit. Thus, direct conversion from thermal energy to
