This study aims to characterize and evaluate seven models of turbulent flow nonself - compensating drippers available in the Brazilian market. The characterization of the emitters followed the pro- cedures of the standards NBR ISO 9261. The experiment was conducted at UNESP University Estadual Pau- lista, Botucatu Campus, Department of Rural Engineering. For the execution of the test one randomly took from each coil, segments containing 25 emitters. In the evaluation of hydraulic and technical characteristics of emitters were determined the following parameters: coefficient of manufacturing variation, coefficients of the characteristic equation of the emitter, thickness of the tube wall, internal diameter, spacing between emitters, water pressure resistance at ambient temperature and 40 o C, the tensile strength of the tube with a tension of 160 N and 180 N, and premature aging testing. The analysis of the drip tapes showed a coefficient of manufac- turing variation of less than 0.056 for all emitters. The exponents ( m ) of the equation pressure versus flow rate ranged from 0.431 to 0.575, classifying them as nonself - compensating. About the wall thickness, the internal diameter of the drip tapes and the spacing between emitters were found out that all measured values are within the required standard. From the results obtained, it can be stated that all products tested and available in the Brazilian market showed satisfactory performance and quality.

– The objective of this study was to evaluate the effects of different water depths and nitrogen fertilization levels applied by fertigation on the physical attributes of guava fruits cv. Paluma. The study was carried out taking into account factors water depths (1144, 1465, 1785 and 2106 mm) and nitrogen fertilization levels (50, 100, 150 and 200 kg ha-1 ). The water depths 1730 and 1750 mm increased production and the average weight of guava fruit in, respectively, 25.1 and 31.6%. The applications 178 and 152 kg N ha-1 increased at 67.1% in the production of fruits and 16.3% the average fruit weight. The combined application of 150 kg N ha-1 and 1789 mm of water amounted to 63.3% of the total weight of fruit. The equatorial diameter of the fruit was influenced by individual water depths applied evidencing an increase of up to 26.8%. Already combinations 200 kg N ha-1 and 1746 mm of water increased the longitudinal diameter of the fruits by 18.77%. The application of water depth to 1144 mm, associated with 143 kg N ha-1 gave index of the most satisfactory way to guava fruit.

Dehydration is an important alternative to making the most of the use the surplus of production and take advantage of the seasonality of tropical fruits. Thus, this study aimed to evaluate the physicochemical composition of the yellow mombin pulp ( Spondia mombin L.) powder, obtained by spray drying, and evaluate its sensory acceptance in the form of reconstituted juice. The physicochemical analyzes of the yellow mombin powder were: pH, soluble solids, titratable acidity, ascorbic acid and moisture, with all results in accordance with the current legislation. The addition of maltodextrin in the process reduced the sensory analysis values (color, appearance, and taste). The tested formulations, (powders with 25 and 27.05% maltodextrin) preserved, and even favored the aroma. These formulations had the following values (7.66 and 7.68) higher than the val- ues found for integral juice (6.60).

The aim of this study was to evaluate the effect of the sowing periods in production , productivity component and physiological quality of seeds of three soybean cultivars (TMG133RR, P98Y70RR and NS7670RR) in Orthic Quartzarenic Neosoil in the cerrado region. The design used was a randomized block a factorial scheme design with four repetitions, and each plot with useful space consisted of three rows of four meters length, spaced at 0.45 meters. Field evaluations were the final stand, the height of the plants, height of the first pod insertion, the mass of 100 seeds and productivity. Already in the lab seeds were evaluated for germination and vigor (first germination count, emergency, emergence speed index, length and dry mass of the aerial part of the plant and roots, electrical conductivity, accelerated aging and tetrazolium test). It concludes that it is possible to use Orthic Quartzarenic Neosoils , located in the Cerrado region at altitudes higher than 600 m, in years and places with good water distribution in the spring - summer seasons, for grain and soybeans production, but as a first goal, the crop should be sown in the first 20 days of November otherwise it should take place in early December.

This study aimed to characterize the lobation and describe the bronchial tree and vasculariza-tion of the lung collared peccaries. 12 animals that died in Multiplication Center of Wild Animals (CEMAS/UFERSA) were used. For analysis of the bronchial tree, the trachea was perfused with latex or vinyl and for identification of arterial vascularization, the pulmonary artery was perfused with red latex. For the visualization of the pulmonary veins, the left atrium was perfused in retrograde direction with blue latex. Likewise we pro-ceeded with perfusion with vinyl. The pieces injected with latex were fixed in 10% formaldehyde for 48 hours and then performed the dissections. Those perfused with vinyl were dipped in a solution of 30% H2SO4 until complete corrosion. The right lung was composed of the cranial, middle, caudal and accessory lobes, while the left lung by cranial (cranial and caudal portions) and caudal lobes. The trachea before of the bifurcation in left and right main bronchi, issued a tracheal bronchus towards the right cranial lobe. The right bronchus gave a branch to the middle lobe, one to accessory and another to the right caudal lobe, while the left bronchus gave a branch to the right cranial lobe (cranial and caudal portions) and another to the left caudal lobe. The study on bronchial and vascular segmentation is useful in clinical and surgical applications, in particular in cases of per-foration, and stenosis or tumors, which require the completion of partial lobectomy.

The millet is a forage with high yield potential, mainly due to its high tolerance to water deficit and adaptation to soils of low fertility. Even being adapted to soils of low fertility, it is responsive to nitrogen fertilization. The objective was to evaluate the growth and nutritional efficiency of millet forage cultivars, due to nitrogen (N). The experiment was carried out in a greenhouse, in a typical Yellow Oxisol Dystrophic. The experimental design was a completely randomized design, arranged in a 4 x 2 factorial scheme with six repetitions. The factors were the control treatment (without fertilization with N) and three doses of N (75, 150 and 225 kg ha-1 ) in the form of urea and ammonium sulfate and two cultivars of pearl millet (BN2 and ADR500). The harvest was performed 80 days after the emergency. The higher production of dry matter of aerial part was obtained with the estimated dose of 179 kg ha-1 of N. The cultivar ADR500 showed the highest height and greater efficiency of translocation, while the BN2 showed higher N content of the aerial part and roots. The greater efficiency of use and translocation of N were achieved with doses estimated for 109 and 133 ha-1 of N for the cultivars ADR500 and BN2, respectively.

The objective of this study was to evaluate the development and the intrinsic growth rate (rm) of Euseius concordis on Tetranychus bastosi on physic nut (Jatropha curcas). The experiment was conducted in incubator BOD at 25 ° C and 70 % RH, with 12h photoperiod environment. The evaluations were performed twice daily for the biology of the mite, and once to the reproductive parameters. The average life cycle of fe-males was 6.3 ± 0.14 days and the males of 6.22 ± 0.14 days. The sex ratio was 0.64, and the average longevi-ty of females was 22.6 ± 2.22 days with an average production of 7,42 eggs per female. The parameters of the life table were obtained : net reproductive rate (Ro), 54,9 individuals ; average length of generations (T) , 7,77 days; intrinsic growth rate (rm), 0,22 female per female per day; finite rate of increase (λ), 1,24 female per fe-male; and in population doubling time (TD), 3,16 days. The E. concordis mite has developed satisfactorily when created with T. diet bastosi, with the short development cycle.

This study was conducted to evaluate seed cotton yield, fiber yield, and fiber quality traits of cotton cultivars grown under different irrigation levels in Brazil. The experiment was conducted over two years in the region of Apodi – RN, with sprinkler irrigation. Treatments comprised of 4 irrigation levels i.e., 130, 100, 70 and 40 % of the crop evapotranspiration (ETc) and 4 cotton cultivars i.e., FiberMax 993, BRS 286, BRS 336 and BRS 335. The experimental design was factorial with randomized complete block design and four replicates. Yield, lint percent and fiber quality traits determined were evaluated. Different responses were observed for cultivars at various irrigation levels. Cultivars grown under limited irrigation exhibited a decline in the seed cotton yield, lint percent, and fiber quality. Cultivars with the highest yield and lint percent were FiberMax 993 and BRS 286. Within irrigation level of 40 % ETc, the medium fiber cultivars produced short fibers whereas the long fiber cultivar, BRS 336, produced medium fiber length. Overall, the different levels of water deficits did not significantly affect fiber quality of the four cultivars tested as all fiber quality traits re- mained acceptable for the domestic textile industry.

The scarcity of the water resources has been becoming an aggravating factor in irrigation of agricultural crops, with that the utilization of treated wastewater arises as a viable alternative to meeting that demand. In this context, the present study aimed to evaluate the effect of the use of wastewater, on growth vari-ables and yield of cotton plants. The research was conducted at Experimental Station of Biological Treatments Sanitary Sewage – EXTRABES, in the city of Campina Grande – PB, in completely randomized design with five treatments and four repetitions. When the treatment 1 (T1) – consisted of irrigation with water refueling coming from CAGEPA; the treatment 2 (T2) – irrigation with effluent coming from the UASB reactor; the treatment 3 (T3) – irrigated with effluent coming from the series of filter; the treatment 4 (T4) – irrigated with effluent coming from the anaerobic filter; the treatment 5 (T5) – irrigated with effluent coming from the ponds of macrophytes. The incremented sodium content in soil at the end of the experiment was 812.9% afforded by irrigation with wastewater coming from the UASB reactor. The application of wastewater through irrigation in cotton culture coming from the UASB reactor and filter in series have increased the concentrations of phospho-rus, potash and organic matter in surface soil layer.

In order study the different management techniques stakes pomegranate 'Wonderful' for vegeta-tive propagation in the dry and rainy season, in the semiarid region of Paraiba. The survey was conducted in the greenhouse, in the Campus Center of Science and Agrifood Technology, Federal University of Campina Grande, in the City of Pombal-PB, Brazil. There were two experiments, one in the dry season, which com-prised from August to December 2012 (Experiment I), and another in the rainy season, from January to June 2013 (Experiment II). Experiments were conducted in a completely randomized design (CRD) with four repli-cations and five plants per replication. To monitor the growth and physiology of the plant was adopted factorial consisting of two factors, managements of cuttings (cuttings with leaves, cuttings without leaves and cuttings without leaves more base incision) in function evaluation times (Days after planting). The propagation material was purchased from commercial plants and cuttings of softwood type. The samples were standardized by size, standard length 15 cm. The management of the cuttings leafless more incision in the base is most suitable for the propagation of pomegranate 'Wonderful'. The management of the cuttings with leaves is not suitable for the propagation of the pomegranate 'Wonderful', in the dry season. The rainy season is the ideal time for the pro-duction of seedlings of the pomegranate 'Wonderful'. The ideal time to obtain saplings of pomegranate 'Wonderful' is 144 days after planting the cuttings.
