25. Optimization of the biodiesel synthesis of physic nut (jatropha curcas L.), via ethanol route, and determination of its uid-dynamic parameters / Otimização da síntese etanólica do biodiesel de pinhão manso (Jatropha curcas L.) e determinação de seus parâmetros fluidodinâmicos
The most applied process for biodiesel production is the transesterification reaction based on alkaline catalysts, due to their faster kinetics and appreciable conversion rate. Then, low cost catalysts (alkaline, alkaline earth and transition metal hydroxides), are often used. In such context, the present work aims to evaluate the catalytic activity of alkal

26. Mycorrhizal association on micropropagated plantlets of Jatropha curcas L. / Associação micorrízica arbuscular em plantas micropropagadas de Jatropha curcas L. (pinhão-manso)
The objective of this work was to evaluate the effects of the arbuscular mycorrhizal fungus (AMF), Glomus clarum, multiplied monoxenically in transformed carrot roots, on the growth, survival, mycorrhizal colonization and root development of micropropagated plantlets in different stages of rooting. Inoculation was performed in vitro and ex vitro conditions.

27. Phenology and photosynthetic capacity of the physic nut (Jatropha curcas L.) in different periods of the year in the state of Alagoas. / Fenologia e capacidade fotossintética do pinhão-manso (Jatropha curcas L.) Em diferentes épocas do ano no estado de Alagoas.
O pinhão-manso (Jatropha curcas L.), pertencente à família Euphorbiaceae, é uma planta nativa das Américas. Encontra-se em processo de domesticação, sendo considerado uma opção agrícola para Região Nordeste, por ser uma espécie xerófita que se adapta a áreas de solos pouco férteis e de clima desfavorável à maioria das culturas alimentares tr

28. Tortas de nabo forrageiro (Raphanus sativus) e de pinhÃo manso(Jatropha curcas): CaracterizaÃÃo e utilizaÃÃo como aditivos na ensilagem de capim elefante / Turnip (Raphanus sativus) and phisic nut (Jatropha curcas) cakes: characterization and use as additives in elephant grass silage
With the advent of biodiesel new by-products are being produced, bringing the need of studies about the viability of use of these alternative feed sources. The experiment was carried out in the Laboratory of Animal Nutrition of the Federal University of Lavras (UFLA) and with the objective to determinate the chemical composition and the in vitro dry matter d

29. Organic fertilization of lettuce with biodiesel co-products. / ADUBAÃÃO ORGÃNICA DE ALFACE COM CO-PRODUTOS DE BIODIESEL
Lettuce is the most consumed salad vegetable in Brazil. Organic production of vegetables is expanding for offering foods with high biological value and exempt of contamination. The acomplishment of this system of production demands the use of natural fertilizers and the like. Thus, studies that prove the quality of organic residues that may act as fertilizer

30. Fruit, seed and seedling characterization and embryo culture of physic nut (Jatropha curcas L.) / CaracterizaÃÃo de Frutos, Sementes e PlÃntulas e Cultivo de EmbriÃes de PinhÃo Manso (Jatropha curcas L.)
Physic nut has a medical and economical importance due to its pharmaceutical properties and increasing interest in fuel industry for biodiesel production, respectively. To be able to attend an increasing demand for Jatropha curcas L. seedlings and to better understand the species, this work aimed to describe its fruit and seed morphologies, its seedling deve
