15. Liquid-liquid equilibria in aqueous two-phase ethanol/salt systems at different temperatures and their application to anthocyanins extraction
Abstract Aqueous two-phase systems (ATPS) are formed by mixtures of chemical species that, under certain conditions, separate into two immiscible phases, with water as the major component in global terms and, at lower concentrations, polymers, salts, ionic liquids and alcohols, depending on the system type. Different parameters influence ATPS equilibrium suc

19. Efecto de la concentración del silano MTMO sobre la protección contra la corrosión de acero electrocincado
ABSTRACT Superficial pretreatments based on silanes are one of the prominent alternatives to replace chromates as temporary protectors from the action of aggressive environments to metallic substrates. The barrier effect afforded by the silane film makes porosity, thickness and film homogeneity important issues in the protective effect. In the present work,

20. Soil organic matter fractions affected by N-fertilizer in a green cane management in Brazilian Coastal Tableland
ABSTRACT The recent approach of eliminating the use of fire for sugarcane harvesting (green cane) resulted in managing the crop on a trash-blanketed soil, which changed the content and dynamic of carbon and the nitrogen requirement. These alterations are relevant due to economic and environmental aspects of sugarcane production systems. This study aimed to e

21. UM NOVO COMPLEXO HÍBRIDO FORMADO A PARTIR DE PIPLARTINA E O ÍON VANADILA: SÍNTESE, CARACTERIZAÇÃO E ESTUDO DA ATIVIDADE BIOLÓGICA
The synthesis, characterization and antimicrobial activity of novel vanadium (IV) complex derived of amide natural piplartine is reported. The minimum inhibitory concentrations (MIC) of complex, piplartine and vanadyl sulphate used in the synthesis were determined against six bacteria and one fungus. The complex exhibited good activity with minimal inhibitor

22. Agronomic performance of green cane fertilized with ammonium sulfate in a coastal tableland soil
ABSTRACT The recent approach of eliminating the usage of fire for sugarcane harvesting resulted in managing the crop on a trashblanketed soil, to which a proper recommendation of N fertilization is lacking, a problem that remains in the coastal tablelands of the Espírito Santo State, Brazil. This study aimed at evaluating the effect of increasing N rates on
