Optimization of the ethanolysis of Raphanus sativus (L. Var.) crude oil applying the response surface methodology.
A quadratic model was investigated to improve the poor predictability of the linear model and resulted in a response surface that was able to predict 97.75% of the total variance of the system. Expand
The influence of BHA, BHT and TBHQ on the oxidation stability of soybean oil ethyl esters (biodiesel)
The effect of synthetic antioxidants such as BHT (butyl-hydroxytoluene), BHA (butyl-hydroxyanisol) and TBHQ (t-butyl-hydroxyquinone) was evaluated on the induction time of soybean oil ethyl estersExpand
(1R,2S,6R)-Papayanol, Aggregation Pheromone of the Guava Weevil, Conotrachelus psidii
Y-tube olfactometer bioassays revealed a strong attractiveness of the papayanol to male and female weevils considering the presence of the plant volatiles. Expand
Esterification and transesterification reactions catalysed by addition of fermented solids to organic reaction media
Abstract We report for the first time both the production of the lipase of Burkholderia cepacia in solid-state fermentation and the biocatalysis of esterification and transesterification reactionsExpand
Identificaton of the Alarm and Sex Pheromones of the Leaf-Footed Bug, Leptoglossus zonatus (Heteroptera: Coreidae)
It is proposed that males are responsible for emission of a sex pheromone in this species, Leptoglossus zonatus, which is mainly found in maize fields in Brazil. Expand
Cuticular Compounds Recognition and Mating Behavior of the Rice Water Weevil Oryzophagus oryzae (Coleoptera, Curculionidae)
Bioassays suggested that males recognized females by their cuticle composition, and couples had intense sexual activity in the first 3 h of photophase and scotophase, meaning water was important for couples to find each other. Expand
