The objective was to determine the adequate conditions for the microwave-assisted extraction of antioxidant compounds from the seed hull of sunflower hybrids. The existence of genetic and environmental variability in the phenolic content obtained under the selected extraction conditions was also analyzed. The extractions were carried out at 70 °C-20 and 90 °C-10 min, using water as solvent and a power...
High oleic hybrids of sunflower are widely cultivated around the world. The effect of temperature on oleic acid percentage of these hybrids is a concern, since oils with oleic acid percentage above a threshold receive a prime over the regular price. The objective of this work was to identify the main avenues for the genetic improvement of oleic acid percentage of high oleic hybrids of sunflower, both...
Reference markers still are required to achieve the highest accuracy in tracking applications. Geometrical patterns allow precisely recognizing objects in image processing techniques. However, researchers are looking for new techniques for the minimization of the error. Post-processing stage was implemented for the refinement of the 3D coordinates computed for flat markers. In our application the...
