Passion fruit is one of the main fruit grown in Brazil and especially in the Northeast by favorable environmental conditions and economic value. In this region the same irrigation with restricted water use has become necessary to maintain adequate production levels, as well as chemical and organic fertilization. In this regard it was held July 2013 experiment to May 2014, seeking to assess the effects of salinity of the water, biofertilizer and bovine types of potassium, in the fertility and soil salinity, growth, mineral composition, gas exchange and production of BRS giant yellow passion fruit. The treatments were arranged in a randomized block design with three replications and 12 plants per plot with factorial 2 x 2 x 2, referring to the electrical conductivity values of irrigation water of 0.35 and 4.00 dS m-1, in the soil with and without bovine biofertilizer and fertilization with two sources of potassium (K2O 60 %), conventional potassium chloride and coated with organic polymers to slow the potassium release during plant growth. The holes were opened in the dimensions 40 x 40 x 40 cm, spaced planting 3 m 2.0 m between plants and between lines. The Irrigation with each type of water was performed every 48 hours with two drip emitters per plant, with a flow rate of 10 L h-1. Were evaluated the fertility were assessed, salinity, moisture and soil temperature, height growth, transplanting period pruning of the main stem and will prune the lateral branches, number of branches to 100 DAT, diameter, mineral composition of plants in macro and micronutrients , gas production and exchange. The irrigation with saline water reduces the average magnesium content in the layer of 21-40, potential acidity, CTC and provided increases in content edafic sodium, Saturation percentage for bases at 0-20 cm, electrical conductivity of the saturation extract in plant flowering period at the end of the drought, the rainy season and foliar nitrogen, iron and sodium. The biofertilizer contributed to the increase in phosphorus, calcium in the layer of 21-40 cm, magnesium and sodium in the 0-20 cm layer, sum of bases, potential acidity, soil organic matter, moisture and soil, soil electrical conductivity, but kept the PST values without sodicity risks, stimulated the growth of plants even in soil irrigated with saline water and foliar phosphorus and zinc, but reduced the foliar sulfur content. The fertilization with coated KCl provided increases in potassium levels, percentage of base saturation and soil organic matter in the 21-40 cm layer, pH of the soil saturation extract at the end of the dry season in the layer of 21-40 cm and rainy 0-20, stimulated the growth of plants irrigated with highly saline water and leaf boron content, but provided a reduction in potassium levels and manganese in comparison conventional KCl. Despite being in nutritional levels lower than recommended, the plants showed satisfactory levels of production components.

In cultivation of yellow passion fruit, the reduction in water application and losses is increasingly essential, has seen the depletion of the world hydric volume in quantity and quality, that associated with the use of organic inputs can help in maintaining the dynamics of edaphic attributes, development of plants, physiological aspects, production potential and fruit quality in the evaluated crops. In this context, an experiment was carried out during the period from November/2016 to October/2017 Remígio municipality , Paraiba State, Brazil, in order to evaluate the effects of irrigation depths reduction from 100 to 60% of evapotranspiration of culture and water losses on soil treated with doses of bovine manure on soil attributes, physiological aspects of plants, plants production and physic-chemical quality of Yellow Giant BRS passion fruit (BRS GA1).The experimental design was a randomized block with subdivided plot, with three replicates, using the factorial scheme 2 × (2 × 5), referring to irrigation depths of 60 and 100% of crop evatranspiration–ETc, pits without and with lateral protectionwith plastic film to reduce soil water losses by lateral infiltrationand doses of 0.0; 2.5; 5.0; 7.5 and 10.0 L of bovine manure per pit.The irrigation depths corresponded to the main plot and the combination between lateral protection of the pits and the doses of organic matter to the subplots. Increasing the dose of bovine manure stimulated the accumulation of nutrients, P, K+, Ca2+, Mg2+, Na+, Beyond the pH, organic matter content, sum of bases, cation exchange capacity, base saturation percentage and humidity, attenuating the temperature in the edaphic environment, especially us irrigated treatments when based on 100% of Etc. The association of bigger irrigation depth with the largest doses of organic matter promoted an increase in indexes of chlorophyll a, b and total, stomatal conductance, internal carbon concentration, photosynthetic, transpiratory rate, instantaneous carboxylation efficiency, production components and physical-chemical quality of fruits. The lateral lining of the pits did not influence in the edaphic attributes, except the organic matter content, but raised humidity and reduced the soil temperature, irrespective of the irrigation depth used. Despite the lateral protection of the pits with plastic film have influenced positively the stomatal conductance, the internal carbon dioxide concentration of the plant sand the average mass of the fruits did not increase the productivity of the crop.

Peanut is an important leguminous at worldwide, widely cultivated in Brazil, mainly in Southeast region. The Northeast have potential for peanut crop, although face the climatic limitations, such as high temperatures and water deficit that could hazard the production. The improvement of cultivars adapted to these conditions is one of the main strategies adopted by breeders in order to leverage the crop in this region. The adoption of statistical tools are essentials, due provide estimates of the proportions of each variation source found in trials. The genetic variance, the coefficient of genetic variation, the heritability and the selective accuracy are the main estimators, meaning a basic assumption for selection procedures and consequent genetic gains. In this work, we estimated the gains obtained through selective practices in peanut genotypes, which findings are reported in two chapters. The first one reports on the selection gains of peanut families RC1F3, resulting from crossing between synthetic amphidioid (A. batizocoi K9484 x A. duranensis SeSn 2848)4x and a commercial cv. BR1 (A. hypogaea subsp. fastigiata), submitted to moderate water suppression aiming to selection of drought. Thirteen RC1F3 families were grown in the field and submitted to 21 days of water suppression. Two early and drought-tolerant cultivars (BR1 and Senegal 55 437) were used as tolerant controls. Eight agronomic traits were adopted to characterize the materials. The mixed models (REML / BLUP) and rank index selection index, proposed by Mulamba & Mock, were uses as selection procedures. We found a relative predominance of residual variance to the detriment of genotypic variance, meaning existence of segregation within the families. High accuracy values were found for most traits. Of the 13 families evaluated, three highlighted based on agronomic traits, with gains for: number of pods/plant, pod length and number of seeds/pod, and also increase of earliness in, at least, 1 day. The second chapter aimed to estimate the selection indexes and economic weights that enable maximum genetic gains in runner peanut. Eleven genotypes were evaluated through nine agronomic traits. The indices used were: Smith and Hazel (SH) classic index, Pesek and Baker (PB) index, Williams base index (W), Elston index (E), Subandi et al. index (S), Cruz index (GI), and the Index based on Sum of Ranks of Mulamba and Mock (MM). The economic weights were: main traits (MT), weight 1 (W1) for all the traits, coefficient of genetic variation (CGv), genetic standard deviation (GSD) and "B" coefficient, obtained through multivariate regression. We found a significant effect of genotypes for all traits (p<0.01), meaning genetic variability among materials. High heritability values were found for most traits (above 90%), indicating genetic progress with selection cycles. The SH-MT, SH-W1, SH-GSD, W-W1 and W-GSD combinations, followed by MM-MT, MM- x CGv, MM-GSD, GI-MT, GI-W1, GI- GSD and E, indicated higher gains for traits related to production, but with unsatisfactory values for Blooming and Cycle. In general, the Mulamba and Mock index was the most promising when applied with W1 in all traits. It was able to balance gains close to the maximum limits obtained through direct selection, for both production and earliness traits.

Brazil is one of the world's largest fruit producers, with a production of more than 41 million tons per year. However, several pests are responsible for causing negative impacts on Brazilian fruit crops, notably the damage caused by fruit fly Ceratitis capitata (WIED, 1824). Females lay their eggs in the fruits, which will be a food resource for the developing larvae, causing significant damage to their quality. New pest control techniques, such as the use of natural products, have been developed, mainly for their effectiveness and degradability. This work consists of two scientific articles. The first article evaluates the insecticidal action of essential oils and entomopathogenic fungi on different stages of fruit fly development, the second; verifies the repellent power of oils on the adult phase of insects and evaluates the chemical composition of guava fruits Psidium guajava L. variety "Paluma" treated with essential oils. The research was conducted at the Invertebrate Zoology Laboratory belonging to the Center of Agrarian Sciences of the Federal University of Paraíba. Citronella, Carnation and Copaíba essential oils and isolates of Metarhizium anisopliae and Beauveria bassiana were used. Topical applications of 2.0 μL of each product/concentration with micropipette aid were performed on 1st, 2nd and 3rd instar larvae and pupae. There was no significant difference between the different types of oils (citronella, clove and copaíba) on larval and pupal mortality when the larvae were treated in the 1st and 2nd instar. When treated in the 3rd instar, there was a significant effect on pupal mortality. The increase in citronella oil concentration continuously increased the repelling potential. The application of essential oils did not negatively influence fruit quality.

This study was conducted to evaluate Soil fauna as environmental bioindicator in Caatinga areas under goat grazing in the Northeast Brazilian semi-arid. The experiment was conducted during one year (October 2013 to September 2014), at the Experimental Farm, belonging to the Federal University of Paraiba, located in Sao Joao do Cariri – PB - Brazil. We used three contiguous areas of Caatinga corresponding to the treatments: T1 (10 goats), T2 (5 goats) and T3 (No goats), each area had a size of 3.2ha with 30 sample units distributed. Were used male goats, adults without defined breed. To organisms soil macrofauna monthly collections was used to trap the type Provid, they remained in the area for 96 hours. Along with this collection was performed the soil mesofauna collection, consisting of soil and litter areas removed with a metal ring help. At the laboratory, the organisms were identified about order. To evaluate the orders diversity were used Shannon and Equitability indices at Past program. The abundance, wealth, absolute and relative frequency was calculated by Excel program. Was collected a total of 16528 individuals of soil macrofauna distributed in 20 orders and 119 mesofauna individuals, distributed in 6 order. The area had no grazing goats had the highest number of macrofauna individuals, with 5993 and mesofauna with 44 individuals. The most common and abundant macrofauna orders groups were Hymenoptera, Coleoptera, Araneae and Scutigeromorpha, and mesofauna: Acarina, Psocoptera and Collembola. The greatest orders richness, diversity and uniformity were found in the area II for macrofauna. The mesofauna showed greater orders richness and diversity in the area III and greater uniformity in the area I. The soil fauna diversity and evenness can be used as an environmental bio-indicator auxiliary of quality in Caatinga areas under goat grazing.

The objective was to evaluate the effects of inclusion of sunflower cake in the diet of lambs in confinement on intake, digestibility, performance and economic analysis of lambs. The experiment was conducted in Aristophanes Fernandes Exhibition Centre, in the city of Parnamirim / RN, over a period of 60 days. 36 crossbred animals were used Santa Inês x Dorper, distributed in four treatments: 0%, 5%, 10% and 15% of sunflower cake inclusion in the diet. Was evaluated daily consumption of DM, OM, MM, CP, EE, NDF, TDN and energy, by-offered plenty of difference, as well as the apparent digestibility of nutrients and feeding behavior of the animals. The performance of the animals body was analyzed through the weight gain data obtained by weekly weighing, and ultimately obtained TWG, DAG and feed conversion. For system economic indicators, it calculated the gross income by the sum of proceeds from the sale of carcasses and no constituent of carcasses, gross margin as the difference between total operating costs-gross income and the cost / benefit of each treatment. The consumption per% BW in gDM / kg of BW and NFC intake showed statistical variation for the inclusion of the pie in the diet, other nutrients DM, OM, MM, CP, EE, NDF, TDN and DE did not differ, but remained according to the analysis of diets, as well as water intake did not differ but remained within the optimal parameters. The animals showed no behavioral differences intake of diet and the digestibility, only CDNFC that differ between levels. Corroborating this result the body animal performance was satisfactory for IW, DAG, CF and WF, with changes only in the WT, but all remained at the ideal weight for slaughter. The economic analysis showed most cost-effective in terms of inclusion of 5% of the pie in MS diets. It can add the sunflower cake in the diet of sheep up in accordance with this research to the level of 15%, and up to the level of 5% the best benefit / cost system.

In intensive sheep production systems, the organization of groups is carried out with the purpose to meet the nutritional requirements of individuals and when a resource is not enough to meet all the members of a particular group, the established hierarchical order allows certain individuals have access priority. Thus, this study aimed to verify the influence of the availability of space at the feeder, position and type of forage on food preference and dominance expression of Morada Nova sheep kept in confinement. We used 36 empty ewes Morada Nova distributed in a completely randomized design in a 3x2 factorial arrangement, three different densities of competition areas trough (0.15, 0.20 and 0.35 m / animal) and two types bulky (elephant grass silage and elephant grass hay) as treatments. The pecking order in each group was determined by feeding motivation test in pairs. The comments were of a type of focal animal sampling with the indirect observation method, using of video cameras (Hero3 GoPro® model) over a period of three continuous hours after delivery of the diet. The daily dry matter intake per animal varied to kind of bulky and animal density in the feeder line. The sheep spent more time feeding silage compared to hay, but there was no difference in the function of stocking density on feeding time in the feeder line. Aggressive behaviors numbers varied depending on the thickness and density was no interaction and social position. The number of aggressive behaviors was high when the sheep were given hay for high density and promoted by high social position animals. The density of 0.15 m / animal in the feeder line allows access to food to all sheep independent of the type of roughage used, but the welfare of animals is affected when offered hay, due to the increase in the level of agonistic interactions. Hay promoted greater food motivation to animals. The social position of Morada Nova sheep is determining when there are limited resources.

Cryptococcosis, leishmaniasis, and cervical adenocarcinoma are challenging diseases for medical chemistry. In order to bring new treatments for these diseases, the in silico studies (ADMET and molecular docking) and organic synthesis have been used to validate new molecular targets and to develop new drugs. Bearing in mind that 2-amino-thiophene and cyclic imides are shown as attractive pharmacophores for these 3 diseases, the aim of this work was to synthesize 2-amino-thiophene-imidic hybrids and perform in silico ADMET and molecular docking studies for new targets key molecules for growth and metabolism microorganisms Cryptococcus neoformans and leishmania and tumor cells like cervical adenocarcinoma, aiming the prediction of compounds potentially more active for these targets, for future conduction of biological tests. Firstly, several synthetic methodologies were tested, among which the solvent-free reaction method at 150ºC was chosen to obtain the different hybrid derivatives. Thiophene-imidic hybrids were synthesized with determined physicochemical characteristics and confirmed structures through 1H and 13C nuclear magnetic resonance spectroscopy, mass spectrometry and X-ray diffraction (for CNF08 and ESF-07). SwissADME and Osiris Property Explore software were used in the in silico ADMET studies, where it was observed that hybrids containing maleimides and phthalimides presented better bioavailability and gastrointestinal absorption profiles, with the CNMA-06 and ESMA-06 compounds showing the best value of drugscore. Most compounds have no potential for interaction with cytochrome CYP450 CYPCD6, CYPC3A4, or P-gp isoforms, especially bis-indolyl hybrids (for example ESDP-06 and IPDP-06). Only IPDP-06 and all bis-indolines may exhibit toxic effects. Molecular docking studies were conducted using Molegro Virtual docking 6.0 software, using 3 to 4 molecular targets for each disease. All molecules presented negative values of interaction energy, indicating great potential to bind with stability and affinity to the selected macromolecules. The best ligands for the targets were the isoindolinesic hybrids, especially bis-indolinic ones, which have -COOEt radical at the C-3 position of the thiophene nucleus. Relating the results in silico ADMET and molecular docking, it was observed that the compound ESFA-06 presented ideal profile for bioavailability and interaction with the macromolecules studied. In addition, bisimides, mainly IPBT-06, have a multi-target profile, for Cryptococcosis, Leishmania and cervical adenocarcinoma, which suggests a great therapeutic potential by stimulating the tests to confirm biological activities.

This study aimed to evaluate diets with different varieties of cactus forage resistant cochineal carmine performance of young goats without defined breed. The experiment was conducted at the Experimental Station of UFPB, located in São João do Cariri-PB. 40 young goats were used without defined breed, with average initial weight of 15 ± 0.96 kg and approximately five months of age in a randomized block design, 4 X 10, four diets and ten repetitions, duration the experiment were 80 days in which 15 were for adaptation diets. The treatments consisted of four diets: control (Tifton grass hay, corn bran and soy bean meal), and diets increased with the varieties of cactus forage (elephant ear, Baiana and miuda).The animals feeding was carried out 2 times a day for 7 h to 15 h. Each animal leftover samples were collected daily and the material offered every 15 days for subsequent determination of nutrient content. For the determination of total weight gain and daily, the young goats were weighed weekly and, for feed, was considered the dry matter intake in kg / day divided by average daily gain weight. To determine the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF) and total carbohydrates (TC), collections were made from animal feces in an in vivo digestibility trial for 5 dias. As observations concerning the feeding behavior of the animals were made into three distinct periods, over 24 uninterrupted hours. The observed and recorded behavioral variables were: idleness, eating, ruminating. The harvest of rumen fluid was performed every 30 days after the day of the beginning of the trial, four hours after the first food supply. After collecting pH readings were taken, and further analysis of AGV. and N-NH3.A collecting blood from all animals was taken to zero and four hours for subsequent biochemical analysis. Slaughter of achievement occurred when the block reached 22 kg of average body weight for carcass quantitative analysis. There were significant differences (P <0.05) for the CMS variables (g / day), CMS (% PC), nitrogen balance and weight gain. Having significance for CMS (P0,75), rumination time, rumination efficiency, pHruminal and NH3 (P <0.05). The N-NH 3 from the control diet showed higher concentrations compared diets with varieties of Baiana and palm miuda. Evaluated blood parameters did not differ between treatments. The use of diets with different varieties of cactus forage SPRD goats do not cause metabolic disorders such does not influence weight gain

Infrared thermography (IT) has been applied among athletes as an indicator of internal training load, with the advantages of being simple and non-invasive. However, its consistency has not yet been determined. The objective of this study was to compare the changes in skin temperature, through IT, induced by an exercise session (acute study - AS) and throughout a training season (chronic study - CS) with changes in physiological measures of inflammation, oxidative stress, muscle damage, autonomic modulation and referred sensation. The participants were 17 athletes (20.9 ± 3.2 years) and 13 athletes (20.4 ± 2.8 years), all of whom were from a semiprofessional basketball team. In AS, the athletes performed a circuit composed of 8 exercises with characteristics of strength, power, eccentricity and speed. Before the circuit, immediately after and after 2, 4, 24 and 48 hours, they were submitted to measurements of heart rate variability (HRV), blood samples for analysis of muscle damage markers creatine kinase (CK), lactate dehydrogenase (LDH), ultra-sensitive C-reactive protein (CRP-us), total antioxidant activity (TAA), malondialdehyde (MDA), and TI. The EC lasted 12 weeks, consisting of technical / tactical / physical training and competitive games. The AS assessments were replicated in the CS every four weeks, plus psychometric tests (mood state, overtraining questionnaire). To analyze the data, we used the ANOVA test for repeated measures and Spearman correlation. The physical exercises of the AD promoted increase of CK and / or LDH for up to 48h post training, but without alteration for PCR-us, CAT and MDA. There was also parasympathetic reduction (RMSSD) and sympathetic increase, but only at the moment immediately after training. At the same time, the whole body temperature (WBT), which was composed by the mean of all evaluated areas, showed a significant increase from 31.3 ± 0.4 ° C, to 32.0 ± 0.5 ° C 2h post training (PT) and 4h PT (31.5 ± 0.5 ° C), reducing PT 24h (30.7 ± 0.5 ° C) and returning values similar to the initial 48h PT (31.4 ± 0.6 ° W). These changes in WBT correlated with PT-CR immediately PT (r = -0.505, p = 0.039), CAT 4h PT (r = -0.533, p = 0.027), MDA immediately PT (r = -0.559, p = 0.020) and RMSSD 24h PT (r = -0.487, p = 0.048). In the EC, muscle damage was observed in the 4th and 8th weeks of training, but the other variables remained without indicating oxidative stress, autonomic disturbance or mood state. Meanwhile, TICI values started at 31.3 ± 0.4 ° C, rising to 31.1 ± 0.5 ° C 4 weeks later and increasing significantly to 31.7 ± 0.4 ° C with 8 weeks of training. The body temperature segmented by body temperature maintained similar behavior to the whole body, with a significant increase in the 8th week of the season. Correlations of TICI with CK (r = -0.487, p = 0.048) and yield (r = -0.487, p = 0.048) with 8 weeks of training and with vigor (r = -0.487, p = 0.048) after 12 weeks. It is concluded that TI data do not consistently follow the physiological indicators of muscle damage, oxidative stress, systemic inflammation, heart rate variability and mood states, either in EA or in CD, but because of some body follow-up, with one or another physiological variable at isolated moments.

The elephant grass stands out among the other used for silage due to high productivity and higher chemical characteristics than the others, having higher soluble carbohydrate content. However, has characteristics that limit the production of silage fermentation profile with suitable, such as high humidity and high buffering capacity. In contrast, the sorghum is a crop for silage indicated by presenting good production and nutritional characteristics. The high content of soluble carbohydrates can trigger undesirable fermentations, increasing losses by changing the nutritional composition and stability of silages when exposed to air. The objective of this research was to evaluate the effects of different proportions of inclusion of sorghum in elephant grass silage on losses, the fermentation profile and aerobic stability of silage. The experiment was carried out in the Forage Section of the Federal University of Paraíba. The design used for the experiments was completely at random, composed of five treatments with four replications. The experiment was carried out in the Forage Section of the Federal University of Paraíba. The design used for the experiments was completely at random, composed of five treatments with four replications. The treatments were represented by different proportions of sorghum in grass silages: 0% (only grass); 25% (25% sorghum + 75% grass); 50% (50% sorghum + 50% grass); 75% (75% sorghum + 25% grass) and 100% (only sorghum), the natural material. They were divided into two experiments. For the first experiment, we used 20 silos for assessing losses of silage fermentation and chemical composition of the silage at the opening of the silos and after 48 hours of exposure to air. For the second experiment, another 20 silos were used; these were completely filled by the material to be ensiled for estimating the total losses during fermentation, and after 48 hours of opening. It was observed effect fermentation period over 30 days and periods of 24 and 48 hours after opening of the silo for enterobacteria, molds, yeasts and lactic acid bacteria. The variables were affected by the inclusion of sorghum proportions in grass silages. After analyzing the results it is believed that when the grass silages are added sorghum silage may improve its qualities. Realize a better performance in the fermentation profile, qualitative characteristics and microbiological profile was to include 50% of the sorghum silages showed satisfactory performance. The inclusion of 50% of sorghum silage promoted improvement in the nutritional value of sorghum silage and reducing nutrient losses in silage.

This thesis proposes the Adaptative Competencies model to analyze the dynamics of the professional's performance in software teams. This model includes a) the constructs and their measurement structure; b) the understanding that these constructs contribute to the transition, action and interpersonal processes of the team adaptive cycles; c) the comprehension that professionals assume different roles within the complex adaptive systems (CAS), in time and space, from the individual e contextual attributes interaction. Three objectives were defined to reach this model: 1) to characterize the competencies of professionals that work in software teams in the light of adaptability; 2) to identify the constructs that compose these competencies; 3) to analyze the relations among constructs to delimit the adaptive competencies model in software teams as CAS. The methodological trajectory involved two moments. First one, a qualitative approach was adopted in which 14 professionals were interviewed, and five teams are observed in a Hackathon event. From the thematic data analysis, it was possible to characterize the competent performance in the light of adaptability. The second moment followed a quantitative approach. The qualitative data has subsidized the construction of an adaptive competence measurement scale. This process included content and face validation from 21 specialists; the application in the first sampling with 233 Computer students for cleaning and adjustments; and a second sample, through a survey, with 454 professionals of software teams. This scale was submitted to validation and reliability evaluation based on exploratory and confirmatory factor analysis. Hence, seven constructs were identified: resilience, self-learning, seeking help, emotional control, problem-solving, coordination leadership, and cooperation leadership. Then, we analyzed the relations among constructs and the contextual team and project variables through Structural Equations Models (SEM), and other multivariate techniques. The findings evidenced the relevance of the technical domain to mobilize the competencies. Also, problem-solving mobilization is largely explained by selflearning, resilience, and seeking help. The problem-solving competency legitimizes the team member to put into action leadership competencies, which is emerging and informal. Besides, we identify five different profiles through cluster analysis that explain three possible roles that the professionals can assume within CAS. The first one is more proactive in which agent helps the system to adapt (adapter agent). The second one, more reactive role in which he/she remains functional even in the face of change (reactive agent). And the third one, in which the professional can create disruptions for the team adaptation (limiter agent). We consider this theoretical-empirical construction, materialized in the adaptive competencies model, brings innovation to the studies about competencies, and it contributes to the people management and IT areas. The constructs that compose the adaptive competencies model, as well as its measurement scale, serve as a starting point for software companies that intends to adopt a competency management model. At a micro level, team managers can better manage available resources to improve team performance since the understanding of agents’ perspective of CAS.

This research had as main objective to analyze the effect that the cultural distance and the peculiarities of market provoke in the economic-financial performance of the companies involved in cross-border mergers and acquisitions processes. The sample consisted of 111 cross-border mergers and acquisitions in the Brazilian market during the period from 2011 to 2016. The survey data were collected from the Thomson Reuters database. In order to capture the effects of cultural distance and market peculiarities on economic and financial performance, the regression model was used with panel data by fixed effects and random effects. In all, two panels were constructed, with about 888 observations for each model variable. From the obtained results it was possible to observe that both the cultural distance and the geographic distance did not present statistically significant values sufficient to infer its influence in the economic-financial performance. However, the positive coefficient of both variables is indicative that a greater cultural and geographical distance would be associated with a higher performance of the companies. In addition, it was found that the level of indebtedness and companies considered to be negatively related to performance and cashfinanced operations produced a positive impact on corporate performance. The evidence indicated that size was an important determinant for the performance of the companies considered in the research. It was also observed that the level of development of the countries also did not report statistically significant values, and it is not possible to confirm their influence on the performance obtained after the merger. On the other hand, the performance tended to be higher when one observes higher level of corporate governance and positive exchange rate effect. With regard to business freedom and commercial freedom, the results were inconclusive and no evidence was found that a greater volume of market capitalization impacts the performance of companies. In this way, it is possible to emphasize that cultural distance and the level of market development do not justify international investment patterns and that possible variations in post-merger performance can be explained by factors commonly explored in the literature, such as size, indebtedness, governance performance and exchange variation, as well as other factors not considered in this research.

The objective was to evaluate the effect of mineral supplementation, organic and inorganic, in the feed of laying Japanese quails and on performance, bone strength, quality and shelf life of eggs. Two experiments were conducted, with 320 layers of Dekalb White lineage distributed in a completely randomized design with two treatments, ten replicates with 16 birds each; and another with 192 Japanese quails also distributed in a completely randomized design with two treatments, six replicates of 16 birds per experimental plot. The treatments consisted of a basal diet formulated to meet the requirements of the birds, supplemented with trace mineral premix in organic form (carbo-amino-phospho chelate) and inorganic (sulfate). The trace elements present in the premix were selenium, iron, manganese, copper and zinc. Statistical analysis of performance data, quality and bone strength were compared by Student's t-test at 5% probability and the nonparametric Kruskal Wallis, and shelf-life data was submitted to the T-Student test function of the mineral source, and function in regression of storage days. In the first experiment, the mineral springs influenced (p> 0.05) feed intake (CR, g), egg weight (PO, g) and mass of eggs (MO, g) of laying; all the quality variables of the eggs were influenced (p> 0.05), except the yolk weight (PG, g) and percentage of peel (PORC%) and the variables on the shelf life also was no influence (p > 0.05) of mineral and interaction between time and source of the mineral sources were observed. In the second experiment, with Japanese quails, there were no differences (p <0.05) in the performance of the birds, the egg quality variables, only Haugh unit (HU) and the shell thickness (EC, mm) were affected ( p> 0.05) and the shelf life variables were influenced (p> 0.05) by mineral sources. The organic source improves the performance and quality of laying eggs and Japanese quails, especially in the variables related to the shell and to maintain the internal and external egg quality in shelf life.

The action of deciding on the basis of diverse information and opinions is one of the great challenges of managers in recent decades. Many relational structures are present in decisions, especially those of a collective nature, that is, decisions made by people at collegiate level. In these types of decisions, social interaction is central when the models and legislation available to support the decision, though in large numbers, are not always sufficient to promote support. When decisions involve legal differences and ethical dilemmas, the manager has to use more deliberative reasoning based on experience and integrative thinking. This thought when socially constructed in collective decisions has a character of action, of emergent conception and complementarity, as a social practice. The idea of practical wisdom - phronesis - of Aristotle (2014) allows understanding the judgments that do not find in the legislation sufficient parameters to mark the decision. Phronesis is a decision subsidy as a practice, considering the common good, or the good of the majority involved with the processes. I understood how opportune to carry out an empirical research in a higher council that makes collective decisions in a public university institution. The Higher Council for Teaching, Research and Extension (COUNI) is a superior deliberative body of a Brazilian Federal University in matters of academic nature, which makes decisions regarding teaching, research and extension in the institution. Thus, this study had the general objective to understand how decision-making takes place as a practice in a superior council of a Brazilian federal university. The structuring of the methodological path was made through observations, interviews and vignettes which were analyzed through the connections between discourse, context and act. This method allowed understanding the decision as a practice, mainly from its involvement with collective phronesis. Authors such as Kinsella (2012), Melé (2010) and Schon (1987), with their empirical evidence on phronetical decisions were taken as a basis for research, as well as Aristotle (2014). The results show the practice of the decision as having four activities that form its nexus: the creation of the processes, the management of the processes by the Secretariat of Administration of the Deliberative Organs of the investigated Institution, the report of the process and the council meeting. In such activities, there are discussions and statements about the interpretation of stakeholder requests, for purposes of both counselors and stakeholders, as well as influencing the rapporteur of their case with documents additional to the request. The legislation that governs the council is also part of the practice, as well as a know-how that guides the activities as an example of stakeholder participation in the meetings. The decision making practice in the council has emotions such as stakeholder anxiety and friendly relations between counselors. In this practice, phronesis occurs in the joint interpretations of the counselors, in the debates, in the actions of each activity propitiated by sagacity, experience, pragmatic resource, dialogical intersubjectivity. However, the decisions of COUNI are not all phronetical. Some deliberative reasoning has no ethical basis for the common good. Theoretical and practical notes justify this result. The main conclusion of this study is that collective decisions and their characteristics are constructors of reality. This reality has nuances, ethical aspects situated, which are influenced by several agents of the practice of the decision for its maintenance over time.

The main objective of this study is to analyze the relationship between success in project management, social and emotional competencies and the engagement of managers. The analysis of the project management environment is intended to contribute to understanding the relationships with social and emotional competencies in managers that is not yet so much discussed in the literature as well as the engagement. The theoretical framework involved three sections: The first one deals with project managers and their competencies. The second presents the socio and emotional competences: concept, dimensions and main authors who collaborated with the construct. The third part deals with the understanding of work engagement, followed by a discussion of the links between success in project management, social and emotional competencies and engagement. To achieve the objectives, a quantitative, exploratory and descriptive research was conducted , using the survey method. The research was developed with project managers affiliated or not to PMI (Project Management Institute) in Brazil. In total, 151 professionals belonging to 15 communities of practice in project management linked to the PMI, as well as professionals working in the project management field but not affiliated. The questionnaire was made available to managers through LimeSurvey software, through the internet with dissemination from a social networking business called LinkedIn. Data analysis was supported by SPSS and R software, through a descriptive analysis, relationship tests, correlation, factor analysis and ANOVA. The results show that there is a relationship between the social and emotional competences of project managers with an engagement that reflects in the better management of the processes in achieving the success of the project. As well as, engagement is a determinant factor in project management, while to achieve project success, the manager sticks to the initial scope of social and emotional competencies that lead to improvements in the project management process. The result of this work may help in the construction or management of the career of these professionals, as well as in the training of future professionals in the development of socio and emotional competencies applied to the context of projects managements that suggest improvement in performance and engagement in the effective work environment. One of the contributions of the study involves the validation of a scale of success in project management. Future studies may use this scale to analyze their relationship with other constructs such as self-leadership and adaptative competences.

El estudio investiga el Programa Nacional Biblioteca de la Escuela (PNBE) articulado a la formación docente en el contexto de las políticas públicas educativas en Brasil, teniendo como objetivo general, analizar el PNBE como instrumento de incentivo y ampliación de los sujetos lectores en la comunidad escolar. Para ello, constituimos los siguientes objetivos específicos: identificar los programas y proyectos referentes a la difusión de libros en la escuela; entender cómo se da la discusión académica acerca del PNBE en Brasil; describir los espacios utilizados para la formación de lectores en las escuelas investigadas y problematizar el acceso y utilización del material suministrado a los profesores a través del PNBE. La investigación se desarrolla a partir de análisis de documentos e investigación de campo, siendo utilizado como instrumento para la recolección de datos, la observación de bibliotecas escolares en dos escuelas públicas ubicadas en la ciudad de João Pessoa, Paraíba. Nos inquietó a descubrir: ¿cómo se da la discusión acerca del PNBE por Brasil? Los objetivos del programa están siendo atendidos? ¿Los profesores de las escuelas encuestadas tienen acceso al material? ¿Cómo se constituye el espacio en estas escuelas para la utilización de las obras? Objetivamos percibir cómo el PNBE y la biblioteca están presentes en el cotidiano de los profesores de dos escuelas del municipio de João Pessoa. Para presentar los resultados de la investigación de naturaleza cualitativa, el presente texto está estructurado en tres secciones. En la primera, identificamos el PNBE en el escenario de las producciones académicas en Brasil entre mediados de 2009 a 2014. En la segunda sección presentamos un breve relato sobre las políticas educativas y el PNBE en Brasil. En la tercera sesión finalizamos la discusión abordando la perspectiva fundamentada a partir de la experiencia vivenciada durante la investigación entrelazando el estudio teórico y la observación de la biblioteca en el espacio escolar de las escuelas analizadas, trazando consideraciones acerca de las experiencias encontradas en el conjunto de los datos e indicando aspectos que aún necesitan ser investigados en la temática abordada.

ABSTRACT Based on three volumes of the Almanach Illustrado do Brasil-Portugal, which totals 610 pages permeated by illustrations, chronicles and a variety of texts destined to the PortugueseBrazilian intellectuals who had the intention to educate and civilize the readers, above all, observing the civic-educational elements present in the almanacs. Produced and edited in Lisbon, these almanacs circulated throughout Brazil, and although a considerable part of the collaborators were Portuguese descent, there was a marked presence of Brazilians in the main sections, as well as correspondents and collaborators spread throughout certain regions of the country. Under the bias of the interdisciplinary approach between cultural history and the history of education, through a qualitative research with a temporal cut from 1899 to 1903, it was emphasized the importance of understanding the civilizing element that substantiated the Portuguese-Brazilian historical relations in relation to sociability networks formation (SIRINELLI, 1996; GOMES, 1993) and the actuation of these intellectuals as cultural mediators (GOMES; HANSEN, 2006), learning with the knowledge of great researchers such as Justino Magalhães (2003, 2010), André Botelho (2002) and Norbert Elias (1993). Among the resources which were used, in addition to the consultation of periodicals published between the end of the nineteenth century and the beginning of the twentieth, BrazilPortugal: revista quinzennal illustrada is also analyzed, highlighting the numbers published in the year 1900, on commemorative matters produced to the IV Centenary of Discovery of Brazil. About the collective profile of Almanach's collaborators, the data point to a group mostly composed of male writers born in the 1850s, concentrating on the age group between 41 and 60 years old, of Portuguese nationality, in which all collaborated in at least one yournal beyond the almanacs and 94% had published books.As a criterion for selecting and analyzing the sources, the trajectory of the Portuguese and Brazilian intellectuals who linked themselves to the magisterium related to their professional activities, as a guideline for the materiality of the almanacs, regarding the categories of education, civilization and produced in the three annuals. It was considered that these categories are intertwined in a PortugueseBrazilian culture with an elitist and Eurocentric veneer, marked by the defense of national education, which had as its background the civilizing discourse, oriented towards progress and modernization. Education assumes the central place as an adequate instrument to attend to the moral and civic values of the society, along with the liberal, conservative and positivist criteria that cultivated and disseminated normative rules for the society in question. Thus, it is concluded that the Portuguese and Brazilian intellectuals in the figure of cultural mediators integrated in networks of sociability – constructed in multiple spatial-temporal dimensions – were involved in the pedagogical and civilizing mission to instruct the public to which they were destined, besides the limits of almanacs. These almanacs bring to light civic-educational elements that, through the propagation of a liberal culture, make possible the multiplication of political and cultural exchanges between Portugal and Brazil, having the language and the common language as an important element of connection and approximation between the two nations.

ABSTRACT This study represents the interest in the play riddles, being this a state of grace and poetry. It brings propositions about the “act of educate” under a ecologic perspective, rising up creativity, the socioenviromental interaction, the emotional-solidary compromise and the reference of poplar tradition knowledge, the main strands for a Eco-educational practice. Sustaining the reflections under a phenomenological bias, the ludic appears from the concept of a creative living that is fuller and more integrated to the life flow. Considering the field experience and the dialectic fruition found in practice with the theory, the reflections land on the learning process. Capoeira Angola, a popular traditional game, appears as the study‟s epicenter. It‟s philosophy, covered by a set of traditional knowledge, basetheir own and free autonomy to the sense of community and the selfimprovement, aspects addressed in the research and developed in a participatory way with children of different ages. This action aimed the strengthening of the premise that the practice of capoeira at school greatly helps the implementation of Laws 10.639/2003 and 11.645/2008, which deal with the theme "Afro-Brazilian and Native History and Culture". Besides acting in a significant way in the generation of a more sustainable and harmonious posture, facing the challenges of coexistence with the world. It was in the interest of the study to try out coordinated pedagogical actions adopted in alternative perspectives to the prevalent teaching model in Brazilian private or public schools. We address in the study the problem of a failed, precarious educational system that, instead of uniting, fragments, "diaspora". The research took place in a university extension format and featured the partnership of schools in the city of João Pessoa / Brazil. Reaching about 120 children in the process of basic institutional education, the project, entitled Brincando Capoeira, started with the premise that capoeira angola keeps in itself an ecological educational cultural power. Thus, we discuss an ideal school dedicated to teaching children and young people as a territory that is potentially friendly to self-expression, to more interactive and integrated living with others, and to less altered nature. Starting from methods based on action-research and ethnography, it traces back to narratives corresponding to the situations experienced in daily praxis, being the experience reports, notes in field journals, as well as transcriptions of speeches from masters and educators we have been in learning situations essential during the process. We presented an ecological concept of the Capoeira Angola Game as a thesis and pedagogicaldidactic proposal. Considered as iconic-imagery data, the photographic records of the classroom situations with the children traced the interpretive impressions of the playful situations, made from the emotional memory resulting from the experiences lived. The expectancy is that this work may serve, in addition to inspiring the belief in the Human Being, in its most sensitive presence to the world, to strengthen capoeira - this Circle of Knowledge – at the schools and other similar spaces, revolutionizing thoughts, re-civilizing people, transforming corporeities.

With the continuous growth in microgeneration processes, studies of electric vehicles and systems that require the process of conversion of the electric voltage, studies of the various elements that compose those systems are necessary. One of them is the DC-DC converter, which will adapt the voltage from a generator system to a value that may be higher or lower than the original, depending on the designed system. Thus, in this work, the study of a DC-DC converter with bidirectionality will be presented, being able to operate with two directions of power flow: from the low voltage side to the high voltage side and vice versa. The topology of the converter chosen was the three-phase push-pull, with the control made by PI controllers and PWM modulation. Simulation results validate the proposed system, also an experimental study is shown.
