Rheological behavior of Chlorella sp. e Scenedesmus sp. cultures in different biomass concentrations REA
Santos,Michel de O. dos; Martins,Márcio A; Coimbra,Jane S. dos R.; Gates,Richard S.; Corrêdo,Lucas de P..
Studies involving the use of microalgae are increasingly intensifying for the potential they present to produce biofuels, because they are a renewable energy source that does not compete directly with food production, and because they enable the obtaining of a fuel with less environmental impact when compared to fossil fuel. In this context, the use of microalgae is directly associated to its capacity to be produced on a large scale and to be extracted from the culture medium. Rheological studies are important for obtaining the information needed in the elaboration of projects and equipment that will be used in various operations existing in systems of production and extraction of algal biomass. In the evaluation of different levels of dry biomass...

SPATIAL VARIABILITY MAPPING OF SUGARCANE QUALITATIVE ATTRIBUTES REA
Ferraz,Marcos N.; Corrêdo,Lucas de P.; Wei,Marcelo C. Fu; Molin,José P..
ABSTRACT Spatial variability evaluation of qualitative attributes can be used as an excellent strategy to design forms of intervention that result in better crop profitability for some agricultural crops, for example, sugarcane. Based on the assumption that qualitative attributes of sugarcane present spatial variability and their distributions along the stems are uniform in different varieties, this study aimed to evaluate the distributions of the qualitative parameters of different sugarcane varieties and the spatial variability of these attributes in a commercial field. Samples of nine varieties were collected for laboratory quality analysis, and the Brix parameter was analyzed by a digital refractometer. The analysis of variance, the Tukey test, and...
