2. Investigation on Prospective Energy Power from Corncob Husk Biomass and its Biochars by Kinetic Parameters and Isoconversional Models
The biofuel properties of biomass play an important role in achieving their utilization on agro-systems and industries. In this context the biomass waste of maize, corncob husk, and its biochars were taken into account to be investigated by thermogravimetric analysis, thermodynamic parameters for non-isothermal analyses using the Ozawa-Flynn-Wall kinetic iso

4. Morphogenesis of dwarf elephant grass clones in response to intensity and frequency of defoliation in dry and rainy seasons
The aim of this study was to evaluate during the dry and rainy seasons the morphogenesis traits of two clones of dwarf elephant grass under different management strategies. The study was conducted in a factorial 2 × 2 × 3 design, using two clones, one green and one purple, two residual heights, 25 and 45 cm, and three frequencies of defoliation according t

11. Fertilizantes de leguminosas: tecnologia inovadora de adubação verde para provisão de nitrogênio em sistemas orgânicos de produção. / Legume fertilizers: innovative technology of green manuring for nitrogen supply in organic farming systems.
One of the main limitations to the organic food production is the reduced availability of low cost and efficient nitrogen (N) sources. Green manuring practices, in rotation or intercropped, have been used, but hardly are they able to supply crop needs. This dissertation presents an innovative technology of green manuring, derived of the cutting, dehydration

12. Study of fast pyrolysis of sugarcane bagasse in a bubbling fluidized bed / Estudo da pirolise rapida de bagaço de cana em reator de leito fluidizado borbulhante
The energy content of biomass can be exploited by direct combustion or after conversion by physical, biological and thermochemical processes. Among the thermochemical processes there is the pyrolysis that is an attractive process because it provokes the conversion of solid biomass into liquids products. Such conversion presents many advantages in transport,
