This study aimed to evaluate the adaptability of Tibouchina granulosa aluminum application. The experiment was conducted in growth chamber using randomized blocks with 5 treatments (0 mg, 8 mg, 32 mg, 64 mg and 128 mg L-1 of aluminum) and 7 repetitions. The plants were influenced by the application of aluminum in the first 30 days after application, being observed a reduction of photosynthetic pigments. However, 45 days after the treatments was observed positive effect of aluminum, also observed that the application of 8 mg L-1 gave the increase of 34%, 71%, 56% and 35% chlorophyll content a, b total and carotenoids, respectively, compared to the control treatment. Therefore, Tibouchina granulosa plants adapted to the aluminum application, also showing that this species may possibly be used in areas of reforestation projects where the soil has high concentrations of aluminum, such as the cerrado soils.

The paper purpose was to examine the technology inclusion of the milk agro-industrial chain in the city of Patos de Minas, in Minas Gerais. It was a descriptive and quantitative research using three business segments. The research involved thirty farmers, two producers associations and two milk processing industries, totaling 34 interviews. The results showed that, in the investigated period, the sector suffered significant structural changes regarding technological diffusion, innovation and logistics, resulting in, among others, a decrease in the number of rural enterprises, improving infrastructure and increasing environmental certifications. Therefore, it can be seen that the environment has changed and that the incorporation of technological innovations by the surveyed sectors, as well as upgrading of the infrastructure have focused on improving the production and processing of milk.

This study was carried out in the Orchard of the Federal University of Lavras (UFLA) to verify the possibility of anticipation of the grafting point of rootstocks of peach tree 'Okinawa', when submitted to different stone- stratification periods (0, 30, 60 and 90 days) in refrigerator 5°C, absence and presence of gibberellin (500 mg L-1 of GA3/24h) and in three environmental conditions (greenhouse, mesh and open sky). After each stratification period, the stones were broken to remove the nuts, which were sown in foam trays and afterwards transplanted to plastic bags, which were maintained in the three environmental conditions. The experimental design was completely randomized factorial 4×2×3, four replicates and 14 nuts per plot. Characteristics evaluated: percentage of total emergence of the seeds, interval between the first and last emergence of seeds, average time to reach transplanting and grafting point. Follows that stones of peach tree 'Okinawa' need a minimum period of 60 day of stratification in damp cold for physiological dormancy of seeds to be overcome; the shortest emergency interval of seeds was obtained at 60 days of stratification and in the greenhouse and by increasing stratification period for 90 days, one manages to decrease the time for plants to reach transplanting point and ideal point for grafting. The use of Gibberellin to overcome dormancy of Okinawa 'peach has not replaced the stratification, not interfering in anticipation of the ideal point of grafting of rootstocks.

Seedling quality is essential for producing quality fruits and keeping the producer revenue. The main goal of this research was to investigate the effect of different environmental conditions and three grafting methods in the production of peach-tree seedlings (Prunus pérsica (L.) Batsch). The experiment took place at the Universidade Federal de Lavras, Minas Gerais State, Brazil. The experimental design was completely randomized, in a 3×3 factorial scheme (three environments: plastic greenhouse, mesh of 50% of shading, and open field; and three grafting methods: shield budding, patch budding, and cleft grafting), with four replications and 12 plants per plot. 'Okinawa' was the rootstocks used, and buddings and grafts originated from the 'Diamante' peach-tree cultivar. The features evaluated were graft- take (%) and time to reach the first formation pruning (days). It was concluded that the mean average graft-take percentage for all three grafting methods was 91.94%, independently of the environment. For all three environmental conditions studied, seedlings grafted according to the cleft grafting method were the fastest ones to reach the first formation pruning, while the patch budding method allowed less time for the first formation pruning, for the open field and mesh environments, when compared with the shield budding method.

Coffee (Coffea sp) is one of the most traditional crops of Brazilian agriculture and its cup quality has been the subject of several studies. The cup quality depends on the pre-processing operations, such as type of crop, stage of maturation of the grain, preparation and drying of coffee. In the coffee tree, the quality of grain depends on the amount of photoassimilates available, mainly in the growth phase or grain filling. Factors such as grain growth, the growth rate of culture, time of growth and grain storage capacity may be limiting the production of culture and the cup quality. The taste and aroma of coffee are complex parameters that are part of the cup quality. These parameters in turn depend on the chemical composition of grain. The accumulation of fotossintatos during the growth of fruit also becomes an important factor in the cup quality, because when the period of grain growth is reduced, a smaller accumulation of fotossintatos and thus a lower quality of drink.

The objective of this study was to evaluate the effect of the application of silicon in the soybean crop. An experiment was carried out in a red latosol soil from December 2007 to April 2008. The estatistical design of the experiment was complete randomized blocks with four treatments (T 1, untreated plot; T 2, a silicon foliar application; T 3, two silicon foliar applications, and T 4, three silicon foliar applications) with three replicates. Each application was 500 ml per hectare of "Silício Samaritá". The first silicon application was carried out in the stage V8 (46 days after the sowing), the second in R 1 (60 days after the sowing) and the third in R 5.1 (88 days after the sowing). Only the third application of the silicon affected the cumulative dry mass of the plants, except for root dry mass. The plants that received three silicon applications presented thicker leaves with the decrease of the specific leaf area (16%, 17.5% and 9.9%) in relation to T 1, T 2 and T 3, respectively. The conclusion is that only as of the third application (T 4) the silicon accumulated in adequate levels for the plant and promoted an increase in the accumulatioon of dry weight and productivity, which was over 20, 18 and 20 bags per hectare in relation to treatments T 1, T 2 and T 3, respectively.

Achieving quality of service (QoS) in IEEE 802.16 networks depends, among other factors, on mechanisms for traffic policing at the base station (BS) and subscriber stations (SSs). Since IEEE 802.16 does not include a mandatory policing, this paper proposes a policing mechanism for the SS in the uplink traffic which uses the leaky bucket mechanism (token bucket). The performance evaluation studies based on modeling and simulation have shown that the proposed mechanism is able to ensure satisfactory levels of QoS to applications, meeting their average limited delay requirements, minimum sustainable throughput and limited packet drop rate. © 2012 IEEE.

The aim of this study was to evaluate the allelopathic effect of soil samples collected under the canopies of three specimens of Copaifera langsdorffii the germination of Lactuca sativa and survey the natural seed bank according to seasonality. To test the allelopathic effect was carried experiments of pre and post-emergence with seeds of L. sativa and to quantify the stock of seeds, soil samples were collected from three specimens at three distances from the stem (1, 2 and 3 m) and at three depths (0-5, 5-10 and 10-15cm) in the region of savanna in the dry and wet seasons. The samples tested in bioassay of pre-emergence no significant influence on germinability, mean germination time and mean germination speed, but showed a difference in the synchronism of germination, these data were independent of sampling station. In test for post-emergence was observed statistical difference in the parameters evaluate (length of primary roots and hypocotyls) in both seasons. To quantify the natural seed bank were macroscopic analysis of each soil sample with the help of stereoscopic microscope. The analysis of the natural seed bank showed a larger number of seeds in the 0-5cm and in distance of 2m for both seasons. The results suggest the presence of allelochemical substances in soil samples collected under the canopy of Copaifera langsdorffii.

The use of Brain-Computer Interfaces (BCI) grows after each passing day. The technology is mainly used for rehabilitation and social inclusion platform in favor of disabled individuals. Using BCI as a method of treatment, one can observe considerable improvements in the functionality of the affected limb which goes as far as enabling once thought impossible tasks. This article consists of a study about BCI and the validation of the obtained knowledge through the development of a 3D simulation system controlled by the BCI, with the main objective of rehabilitating people with upper body limitations. The methodology consists in capturing brain waves and cognitive information with a neural headset, which sends the data to an application to analyze and convert said data into various actions the 3D simulator can execute. Then, the user undergoes a series of neural tests, where he can move two virtual arms with the power of thought interacting with the simulated environment. To increase the realism and immersion of the environment, virtual reality goggles were integrated into the simulator. The results obtained were mostly satisfactory. It can be concluded that the BCI can help in the rehabilitation of people with upper body limitations in a more dynamic way, with the added possibility of reutilizing the developed BCI in other types of analysis or rehabilitation. © 2016 IEEE.
