title: Estimation of Pico-Satellite Attitude Dynamics and External Torques via Unscented Kalman Filter

description: ABSTRACT: In this study, an Unscented Kalman Filter (UKF) algorithm is designed for estimating the attitude of a pico-satellite and the in-orbit external disturbance torques. The estimation vector is formed by the satellite's attitude, angular rates, and the unknown constant components of the external disturbance torques acting on the satellite. The gravity gradient torque, residual magnetic moment, sun radiation pressure and aerodynamic drag are all included in the estimated external disturbance torque vector. The satellite has magnetometers and gyros onboard as the attitude sensors. Because of the inherent nonlinear dynamics and the nonlinear measurement model, the UKF, which is a nonlinear version of the Kalman Filter, is selected as the filter algorithm. Performance of the proposed algorithm is demonstrated via simulations for a cube pico-satellite and the results are analyzed for different scenarios.

title: COEFFICIENT OF PERFORMANCE PREDICTORS OF SET VICTORY IN SCHOOL VOLLEYBALL

description: ABSTRACT Technical-tactical performance is essencial to victory in volleyball, so it is important to identify indicators associated with winning the set. Thus, the aim of this study was to identify and associate the technical-tactical coefficient of performance based on the result of the set in the school female volleyball. School athletes participated in the study (age between 12-14 years old). 27 match were analyzed, resulting in 57 sets, 7194 actions (serve= 2380, serve reception= 2157, set= 1358; and attack= 1299). Subsequently, the performance coefficient per action and set was calculated. Binary logistic regression was used to verify the association of the performance coefficients with victory of the set. The serve performance coefficient classified as "good" proved to be a major victory predictor set (OR= 29.46), followed by set classified as "good" (OR= 15.87), and attack classified as “good” (OR= 7.32). The serve is the major predictor in the present study, followed by serve and attack. These results suggest that serve should be prioritized in training, as it increases the chances of victory.

title: Famennian glaciation in the eastern side of Parnaíba Basin, Brazil: evidence of advance and retreat of glacier in Cabeças Formation

description: ABSTRACTGlaciotectonic features studied in the siliciclastic deposits of Cabeças Formation, Upper Devonian, represent the first evidence of Famennian glaciation in Southeastern Parnaíba Basin, Brazil. Outcrop-based stratigraphic and facies analyses combined with geometric-structural studies of these deposits allowed defining three facies association (FA). They represent the advance-retreat cycle of a glacier. There are: delta front facies association (FA1) composed of massive mudstone, sigmoidal, medium-grained sandstone with cross-bedding and massive conglomerate organized in coarsening- and thickening-upward cycles; subglacial facies association (FA2) with massive, pebbly diamictite (sandstone, mudstone and volcanic pebbles) and deformational features, such as intraformational breccia, clastic dikes and sills of diamictite, folds, thrust and normal faults, sandstone pods and detachment surface; and melt-out delta front facies associations (FA3), which include massive or bedded (sigmoidal cross-bedding or parallel bedding) sandstones. Three depositional phases can be indicated to Cabeças Formation: installation of a delta system (FA1) supplied by uplifted areas in the Southeastern border of the basin; coastal glacier advance causing tangential substrate shearing and erosion (FA1) in the subglacial zone (FA2), thus developing detachment surface, disruption and rotation of sand beds or pods immersed in a diamicton; and retreat of glaciers accompanied by relative sea level-rise, installation of a high-energy melt-out delta (FA3) and unloading due to ice retreat that generates normal faults, mass landslide, folding and injection dykes and sills. The continuous sea-level rise led to the deposition of fine-grained strata of Longá Formation in the offshore/shoreface transition in the Early Carboniferous.

title: MOTIVATIONAL PROFILE AND EMOTIONAL INTENSITY IN SCHOOL BASKETBALL: PREDICTOR VARIABLES

description: ABSTRACT This research investigated the capacity that game characteristics and protagonists have to predict emotional intensity, as well as motivational orientation (towards performance or outcome). A total of 183 elementary and high school students from four Spanish regions joined the study (boys = 43.7% and girls = 56.2%), aged 12 to 17 years old. Two 60-minute intervention sessions were carried out (15-20’ per game); emotional intensity was assessed at the end of the session using the GES, whereas motivational profiles were assessed through the BREQ3. For data analysis, the decision tree technique known as CHAID was employed. The findings allow highlighting that: a) competition result and game type can predict the participants' emotional intensity; b) result during the match, along with gender, can predict performance-oriented motivational profiles; and c) gender and result, in addition to sports background, help predict motivational profiles not oriented to performance.

title: INITIAL HEIGHT AND DEFERMENT PERIOD ON SIGNALGRASS PASTURES

description: Abstract This study aimed to evaluate the initial heights (10, 20, and 30 cm) and deferment periods (171, 141, and 109 days in 2010; and 131, 100, and 71 days in 2011) of Urochloa decumbens cv. Basilisk (signal grass). The factors were arranged in split plot, in a randomized complete block design with three replications. Pastures deferred for a short period had lower masses of forage (5,977 and 6,904 kg/ha of DM in 2010 and 2011, respectively). In 2010, pastures deferred for a short period had lower mass of live stem (942 kg/ha of DM), dead leaf blade (785 kg/ha of DM), and dead stem (1282 kg/ha of DM), higher number of vegetative tillers (797 tillers/m²), fewer reproductive tillers (2 tillers/m²), less falling index (1.4), higher mass of live leaf blade (655 kg/ha of DM). The higher pastures had fewer vegetative tillers (495 and 431 tillers/m² in 2010 and 2011, respectively), larger masses of forage (5,285 and 5,942 kg/ha of DM in 2010 and 2011, respectively), dead leaf blade (968 kg kg/ha of DM in 2010) and dead stem (1,902 kg/ha of DM in 2010). Based on the results obtained in the two years, for use in July, the signal grass can be deferred for 71-109 days with an initial height of 20 to 30 cm. The initial height of 10 cm is recommended when a deferral period above 130 days is adopted.

title: ETHOLOGICAL ANALYSIS RELATED TO THE PROCEDURE OF WEARING OR NOT THE TEETH OF PIGLETS IN MATERNITY

description: Abstract The objective of this study was to evaluate the behavior of piglets and sows regarding the treatment of wearing or not the teeth of the piglets. Sixty-seven swine matrices and 827 piglets were used. The experiment was performed in three locations and the behavioral data was obtained from the ethogram, in the directed form. Piglets were observed every ten minutes for four hours, three times a week. The data were analyzed in a completely randomized design with repeated measures in time. The mixed model was used with the fixed treatment effect, shift, period and their interactions, and the random batch effect using the MIXED procedure of SAS (2008). Fifteen structures of variance and covariance were tested, choosing the one that presented the lowest value for the Akaike Information Criterion (AIC). No significant effects were found for the agonistic, stereotyped, playful, and exploratory behavior in relation to the treatments as well as for the whole period evaluated (P&gt;0.05). Significant effects were identified on the suckling behavior, comparing the treatments (P≤0.05). No significant effects were found for the dietary behavior of the matrices (P&gt;0.05). The study differed from drinking for the period evaluated (P≤0.05). Permanence or not of the piglets' teeth can affect important behaviors such as suckling, which is responsible for the efficient weight gain. The wear of the teeth may be unnecessary due to the injuries caused as a result of the mismanagement of this practice. More studies on this theme, seeking further elucidations, are necessary

title: ASCORBIC ACID IN EXTENDER FOR CRYOPRESERVATION OF GOAT SEMEN

description: Abstract The objective of this study was to determine the optimal inclusion level of ascorbic acid in TRIS-yolk extenders for cryopreservation of goat semen. We used five ejaculates of three Anglo Nubian goats. Semen from each animal was divided into four 200µL aliquots, composing four treatments: no addition of ascorbic acid (control) and 0.0528, 0.1056, and 0.1584mg/mL of ascorbic acid in TRIS-egg yolk. We evaluated motility and sperm vigor after dilution, post-cooling, and post-thawing; membrane integrity (HOST); acrosomal integrity, and slow thermoresistance test (TRT). Data were subjected to regression analysis at 5% probability. There was no difference for the progressive motility and sperm vigor, respectively, in the post-dilution, after cooling and post-thawing, as well as the additional tests HOST and after 120 minutes of TRT, for motility and force, respectively, in post-thawing (P&gt;0.05). There was a quadratic effect with the addition of ascorbic acid to the acrosome integrity parameter, presenting a great maximum level of 0.1006 mg/mL ascorbic acid for acrosome integrity of 61.58% (P&lt;0.05). The addition of ascorbic acid was effective in maintaining sperm viability, especially acrosome integrity during the cryopreservation process until the level of 0.1006 mg/mL, and it may be an alternative composition of seminal extenders for goats.

title: PRODUCTIVITY OF PEARL MILLET THREE SOWING DENSITIES AND TWO CUTTING HEIGHTS

description: Abstract To evaluate the production of pearl millet (Pennisetum glaucum (L.)) at different sowing densities and managed under different cutting heights, a field trial was carried out in the experimental farm of Universidade Federal de Goiás, from March to July (off season crop) after the soybean harvest. A completely randomized block experimental design in a factorial arrangement (3x2) with three sowing densities (10, 15, and 20 kg.ha-1) and two cutting heights (50 and 70 cm) was used. Data were analyzed with SAS® 9.2 (SAS Institute Inc., Cary, NC), considering the density effect in the plot and the height in the subplot. Means were compared by Tukey test. The sowing density did not affect (P&lt;0.05) green mass and dry matter (DM) production. In the comparison between cutting height, the height of 70 cm had higher DM production. However, the total production of the period was not affected (P&gt; 0.05) by sowing density and height management. Total production per hectare was similar between densities and cutting heights. As the cutting height did not affect DM production and allowed a longer period of pasture utilization and lower deployment cost, we recommend a sowing density of 10 kg.ha-¹ and millet cut at 50 cm.

title: SWARD STRUCTURE AND TILLER CHARACTERISTICS IN PIATÃ GRASS PASTURES MANAGED WITH VARIABLE NITROGEN DOSES AND DEFERMENT PERIODS

description: Abstract This study was conducted from Feb. 25th, 2012 to Jul. 1st, 2012 to recommend nitrogen doses and deferment periods that result in deferred Brachiaria brizantha cv. Piatã (piatã grass) pastures with structural characteristics suitable for animal consumption. Combinations were evaluated between deferment periods and nitrogen fertilization conditions. The deferment periods were long (127 days) and short (79 days). Nitrogen doses were 0, 40, 80, and 120 kg/ha. The experimental design was a randomized block with three replications. The leaf area index (LAI) and light interception (LI) increased with the application of nitrogen. In the absence or at a small nitrogen dose, pasture deferred for short periods presented lower LAI and LI than pasture managed with long deferment period. The nitrogen only influenced the density of vegetative basal tillers. The lower deferment period resulted in a greater number of basal tillers and vegetative air, as well as fewer reproductive basal tillers. Nitrogen increased the length of the leaf blade and the vegetative tiller stem. Long deferral period resulted in longer stem and leaf blade and a larger number of dead leaves. Piatã grass can be deferred for 80 days, with application of 80 kg/ha of nitrogen at the beginning of the deferment period.

title: MEAT QUALITY OF RODHE ISLAND RED POULTRY REARED IN ALTERNATIVE SYSTEM

description: Abstract This study aimed to characterize the quality of the meat from Rodhe Island Red poultry, considering the type of cut and sex. We used 30 birds in a completely randomized design in a factorial arrangement (2 x 2), two cuts (breast and thigh) and both sexes, with five replicates per treatment. The birds were slaughtered at 105 days to carry out the physical and chemical analysis, chemical composition and lipid profile of breast and thigh. The thigh showed the highest mean final pH, redness (a*) and shear force (SF). For brightness (L*), the breast had the highest average as well as females presented the highest SF average. The thigh presented the highest amount of ether extract (EE) and humidity. The breast presented the highest amount of saturated fatty acids. Females showed the highest amount of ω3 and the lowest ω6 / ω3 relation. There was a higher thrombogenicity index in breast meat. The thigh showed the lowest content of saturated fatty acids and a lower thrombogenicity index. Females had higher content of ω3. The cut showed greater influence then sex on the studied parameters and the thigh showed better physical and chemical aspects and lipid profile for poultry meat in such production system regarding the meat quality as desirable by the consumers.
