“…Among these species, Prosopis sp. stands out due to its forage, timber and firewood uses (Andrade et al 2010), as well as Ricinus communis, used for biofuel (Tabile et al 2009), and Cenchrus ciliaris, used for forage (Silva et al 1984).…”

This paper is the result of a survey of the alien flora present on fluvial islands in the São Francisco River, northeastern Brazil. The floristic similarities between the islands wereassessed, as well as the relationship between area size and species richness. The study covered eight islands in the São Francisco River Valley and was carried out in a period of eight months. Thirty one alien species were registered, six of them (Amaranthus viridis, Calotropis procera, Cenchrus ciliaris, Enneapogon cenchroides, Prosopis pallida and Ricinus communis) present on all islands. The highest number of invasive alien species (26) was recorded on Massangano Island. The floristic similarity between the islands varied between medium and very high, while the number of alien species present was positively correlated with area size. The study demonstrates that the biodiversity on these eight fluvial islands is endangered, especially due to the presence of alien species capable of invading natural areas.

“…De acordo com Tabile et al (2009), diversos estudos sobre o desempenho operacional de motores utilizando biodiesel não apontaram indícios de aumento de desgaste, comprometimento de potência ou redução na durabilidade; entretanto, vários autores observaram aumento no consumo de combustível à medida que se aumenta a proporção de uso do biocombustível. Castellanelli et al (2008), trabalhando com misturas de biodiesel etílico de soja em motor de injeção direta, constataram que as misturas de biodiesel B2, B5 e B10 apresentaram desempenho semelhante ao do diesel, e o biodiesel B20 apresentou desempenho superior ao do diesel.…”

ResumoA crise energética, associada ao aumento da demanda por combustíveis e à crescente preocupação com o meio ambiente, tem levado à busca por fontes alternativas de energia. Além disso, a entrada de novos equipamentos e máquinas agrícolas altamente competitivos, em termos de custo, vem despertando o interesse dos agricultores. No entanto, tais equipamentos, pela sua recente inserção no mercado, ainda não apresentam parâmetros que os remetam à confiabilidade. Nesse contexto, este estudo visou ao ensaio dinamométrico de tomada de potência (TDP) de um trator agrícola da marca Green Horse, modelo 204, para obtenção de suas curvas de desempenho, utilizando como combustível misturas de óleo diesel e biodiesel de soja, nas proporções B2, B5, B20 e B100 . Os resultados mostraram que o trator apresentou desempenho motor compatível com outros modelos de mesma potência utilizados no país, apresentando o melhor desempenho com o uso do combustível B5 . Palavras-chave: Biocombustível. Motor diesel. Máquinas agrícolas.

“…is an oleaginous of high socioeconomic value, in Brazil the commercialization of production, in 2015 generated approximately R$ 67 million (IBGE, 2015). Its products and by-products are used in industry and agriculture, as well as presenting perspectives of use as an energy source in the form of biodiesel (Tabile et al, 2009).…”

Article AbstractThe choice of the most appropriate method is determined by the precision desired by the researcher, by the ease of the analysis, as well as by the way of obtaining the data. In order to select lineages of low size and high productivity this study aimed to evaluate different methods of cluster analysis in the representation of genetic divergence, compared to univariate methods. The analyzed variables were grain yield, plant size and oil yield of 24 lineages of castor beans cultivated in the years 2014 and 2015. The Single and Average methods presented similar results in the formation of groups and different from the Complete. Evaluating the purpose of this research the Complete method and principal components analysis, together with the discriminant analysis, were considered the most appropriate methods to evaluate the genetic divergence of the castor bean crop. Lineages 18, 19 and 20 showed average grain yields above 1555 kg.ha -1 , high oil content (above 46.9%), and low size plants (below 116 cm).
