Brazilian agribusiness has a history of continuous generation of trade surpluses, even in adverse economic scenarios. To assess whether reference companies in the sector also showed favorable results in recessionary scenarios, without the occurrence of abnormal returns, it was verified whether, within a set of factors selected to explain the return of BrasilAgro and SLC Agrícola common shares, they would be val...
The combustion with fluidized bed reactors has as main advantages the best energy utilization of combustible materials and a lower generation of pollutants. The fluidization success depends on the characteristics of the particles that compose the bed. This research aimed to perform a preliminary evaluation and characterization of the energy potential and the fluidization curves in fluidized beds formed by binar...
A maioria do povo Brasileiro não tem habitualidade de investir em opções diferentes da poupança. Este artigo apresenta o objetivo de verificar qual o principal motivo dos Brasileiros não investirem com habitualidade em ações. Para tal, foi elaborado um instrumento de pesquisa e aplicado para cem brasileiros, entre 20 a 39 anos, de diferentes estados. Por fim, após a análise dos dados obtidos, foi constatado que...
The multi-enzyme complex (crude extract) of white rot fungi Pleurotus ostreatus, Pleurotus eryngii, Trametes versicolor, Pycnosporus sanguineus and Phanerochaete chrysosporium were characterized, evaluated in the hydrolysis of pretreated pulps of sorghum straw and compared efficiency with commercial enzyme. Most fungi complexes had better hydrolysis rates compared with purified commercial enzyme.
The objective of this work was to optimize the total cellulase activity of the crude extract cocktails from five white rot fungi produced by solid-state fermentation, by means of the central composite design. The white rot fungi Pleurotus ostreatus PLO 06, Pleurotus eryngii PLE 04, Trametes versicolor TRAM 01, Pycnosporus sanguineus PYC 02 and Phanerochaete chrysosporium PC were tested. For optimization process...
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior; Brazil is the main producer and exporter of sugar in the world. For 2008, its production is estimated to reach more than thirty million tons. One requirement for exportation of the sugar is its coloration, that must be in accordance with the International Commission for Uniform Methods in Sugar Analysis - ICUMSA. The color ICUMSA (sugar) can also be a...
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior; With the objective of replacing fossil fuels, at least partially, in recent decades the interest in alternative energy sources has increased. In this context, considering the increasing development of the Brazilian sugarcane industry, sugarcane straw has been gaining increasing prominence as a feedstock for biofuel production. Given the close recalcit...
Atualmente as castanhas têm recebido atenção especial, pois são fontes naturais de vitaminas, minerais, proteínas e ácidos graxos essenciais, podendo assim contribuir para a dieta humana e de animais. Pesquisas recentes confirmam que esses alimentos são fontes ainda de compostos bioativos, os quais podem trazer benefícios significativos à saúde humana. Este trabalho teve como objetivo avaliar a composição quími...
