Abstract The scarcity of conventional fuel and stringent emission norms made researchers to look after alternative fuels run an internal combustion engine . One the possible alternatives for Compression Ignition is biodiesel. Although there are some challenges such as high viscosity, low calorific value, carbon deposit on injector nozzle , etc. To overcome these challenge nanoparticles added wh...

White rot fungi have one of the most efficient oxidative lignin degradation systems, and present an enzymatic complex that is responsible for digesting lignocellulosic matter. The aim this study was to evaluate production laccase total peroxidases by Ganoderma lucidum via solid-state fermentation using açaí seeds marupá (Simarouba amara) sawdust unsupplemented supplemented with wheat, corn rice...

Growth performance was assessed for a diverse suite of canopy and emergent tree species in a lowland neotropical rain forest (the La Selva Biological Station, northeastern Costa Rica). Species were evaluated based on annual diameter measurements of large samples of individuals in all post-seedling size classes, over a 12-yr period. The study species were seven non-pioneers (Minquartia guianensi...

O ensaio de flexão estática em três pontos, acordo com a norma ABNT NBR 7190-3:2022, permite determinação duas propriedades da madeira: o módulo elasticidade e valor convencional resistência. De esta norma, do deve ser por meio ciclos carregamentos que ocorrem entre 10 50% carga ruptura um corpo prova estimativa. Entretanto, é usual realização destes utilizando parâmetros flecha, normalmente L/...
