The present study was carried out to evaluate the antioxidant activity of and the content of bioactive compounds in camu-camu fruits harvested at different maturation stages and stored. The fruits were harvested in the municipality of Cantá, Roraima State, Brazil. The experimental design was completely randomized, with three replications, in a factorial arrangement consisting of three different maturation stages (immature, semi-mature and mature) and eight days of storage (3 x 8). The fruits were analysed every day regarding total vitamin C, carotenoids, anthocyanins, flavonoids, total phenolic compounds, and antioxidant activity (FRAP and DPPH). According to the results obtained, the interaction of maturation stages x eight days of storage had a significant effect according to the F test at 5% probability. The highest antioxidant activity (FRAP) was observed in the fruits harvested in the semi-mature stage, providing a longer shelf life. The carotenoid pigment, flavonoid, anthocyanin, and vitamin C contents were higher in the fruits harvested in the mature stage, and this stage was the most suitable for obtaining these functional biocompounds. Additionally, in mature fruits, the highest mean content of total phenolics and antioxidant activity (DPPH) were observed during storage. It was concluded that the mature stage is the most recommended for the extraction of pigments and antioxidant biocompounds from camu-camu fruits. |

Along the past years, many interaction devices had been introduced to support the interaction between humans and computers, as the digital pen, touch sensitive devices and, more recently, gesture recognition devices. The last one allows a human-computer interaction using only the user's body movement, turning the interaction more "natural". However, these natural user interfaces (NUI) are still based on a pre-defined set of commands and are still not as natural as we desire. In this work, we questioned the benefits of the NUI over the mouse and keyboard combination. This work presents some improvements on the NUI system for Geographic Information Systems (GIS), the NInA framework. Results showed that a NUI approach demands a short learning time, with just a couple of interactions and instructions, and the user is ready to go. Moreover, the users demonstrated greater satisfaction, leading to productivity improvement. |
