Análise da influência da temperatura sobre propriedades físico-químicas de amostras de diesel, biodiesel e suas misturas
(Universidade Tecnológica Federal do ParanáMedianeiraPrograma de Pós-Graduação em Tecnologias Ambientais, 2015-03-30)
Fuel quality is a major factor affecting the performance of internal combustion engines and it is characterized by a combination of physical and chemical properties. In this study, the influence of temperature on some ...
Structure of a glycoglucuronomannan from the low-viscosity gum of Vochysia lehmannii
(Elsevier B.V., 2004-09-13)
The polysaccharide (VSP) from the gum exudate of quaruba (Vochysia lehmannii) had two components of almost identical M. centred at 24,800, as shown by HSPEC-MALLS. The presence of aggregates was shown since carboxy-reduction ...
