Magonia pubescens is a tree species originally from the Brazilian Cerrado that bears fruit with winged seeds from which fixed oil can be extracted. This study aimed to analyze the physical and chemical properties of the oil extracted from these seeds and the biodiesel produced thereof. Methods from the Adolfo Lutz Institute, American Oil Chemists Society, and American Society for Testing and Materials were used. Seven fatty acids (oleic, arachidic, gadoleic, palmitic, palmitoleic, linoleic, and stearic acids) were found in the oil. ).

Abstract. New alternative energy has been an interesting field for research and development in attempt to diminish the environmental imbalance that has occasioned several climatic changes occurred over the past decades. This research area has obtained a great advance in methodologies to produce alternative energies, where is possible to produce energy through alternative sources that usually are less polluting and are useful to replace the crude oil and petroleum derivatives. These alternative energy sources have become an important tool in the fight against pollution. Among some alternatives energy, stands out biodiesel an available alternative fuel, which is capable to diminish problems related to important areas as environmental and social development. From this point INMETRO, has developing, in line with the policy of the Brazilian government, studies to obtain alternative and renewable sources of energy as bioethanol and biodiesel. This work shows a methyl biodiesel short-time stability study in attempt to observe how much temperature can affect the biodiesel quality. Were used two methodologies to verify the biodiesel quality, the oxidative stability by Rancimat method and Iodine Index.

“…In the last few decades, the Brazilian agribusiness became the main economic activity in the country, mainly because of the gains in crop yields, motivated by the technological advances promoted by the intensive investments on agricultural research and development. Among the crops with high importance for the country, soybean [ Glycine max (L.) Merrill] is the most valuable, being exported for several countries around the world and also used internally in the agroindustry, for oil production and animal feeding, as well as in the chemical and food industry (Costa Neto and Rossi, ; EMBRAPA, ; Gomes, ).…”

Alternative sowing dates as a mitigation measure to reduce climate change impacts on soybean yields in southern Brazil

ABSTRACT:The climate and its variability is the main risk factor for the success of soybean crop in southern Brazil. Such aspect becomes even more important under the future climate scenarios, in which global warming is expected. Based on that, the objectives of this study were to identify the impacts of raising temperatures on soybean yields in southern Brazil and how management strategies represented by changing sowing dates could be able to mitigate them. The soybean yields for the present and future scenarios were estimated by the crop simulation model CROPGRO-Soybean calibrated for southern Brazil. The simulations were done for 13 locations distributed in the states of Paraná, Santa Catarina and Rio Grande do Sul, considering climatic series of 31 years. The future climate scenarios were built based on downscaling temperature changes from ETA and PRECIS models for the periods: 2013-2043 (D25) and 2041-2071 (D55), without considering the increase in the atmospheric CO 2 concentration. The soybean potential (Y p ) and attainable (Y a ) yields and their relationship (Y a /Y p ) were estimated for all scenarios and used to determine the climatic risk for the crop. In order to investigate how to mitigate the global warming impacts on soybean yields, different sowing dates, two earlier and two later than the present recommendation, were simulated in the crop model and resulting yields were compared. In general, raising temperature will lead soybean crop in southern Brazil to lower yields, for both Y p and Y a , with higher impact on Y a , independently of the climate model used. Also, the climatic risk for the crop will increase in the future climates scenarios. The strategy of changing the sowing date showed to be feasible to reduce the impacts of raising temperatures on soybean yields, but only when it is delayed in relation to the sowing period presently recommended for this crop in the region.
