title: Effect of different light curing units and immersion media on roughness and color of a nanofill composite

description: Abstract Introduction The excessive consumption of soft drinks seems to change the properties of composites and may be associated with the light curing unit. Objective To evaluate changes in surface roughness (ΔR) and color (ΔE) of one composite polymerized with different light sources, immersed in distilled water or in Coca-Cola®. Methodology Sixty samples of nanofilled resin (FiltekMR Z350 XT, 3M) were distributed into following light curing units: a) quartz-tungsten-halogen (QTH) light; b) light emitting diode (LED) with polymer tip (LED 1) and c) LED with optic fiber tip (LED 2). Half of each group (n=10) was kept in water or immersed in Coca-Cola® for 20 minutes 2x/day during 14 days. Data were submitted to the Mann-Whitney and Kruskal-Wallis tests (p≤0.05). Result The ΔR was not significant among groups: in water: QTH = 0.006; LED 1 = 0.019; LED 2 = 0.010 (p=0.33); in soft drink: QTH = 0.021; LED 1= 0.011; LED 2 = 0.030 (p=0.86). The ΔE was not significant among light curing units: in water: QTH = 1.40; LED 1 = 1.80; LED 2 = 1.60 (p=0.31); in soft drink: QTH = 2.51; LED 1= 1.91; LED 2 = 2.61 (p=0.41), but was significant compared the immersion media (p=0.01), except for LED 1 (p=0.54). Conclusion The light curing lights did not interfere with the surface roughness and with color of nanofilled composite. Daily dives in soft drinks did not change smoothness, but the color changed to visually perceptible way, though clinically acceptable, according to the scientific literature parameters.

title: MINERAL NUTRITION OF CRISPHEAD LETTUCE GROWN IN A HYDROPONIC SYSTEM WITH BRACKISH WATER

description: ABSTRACT Water availability in the Brazilian semiarid is restricted and often the only water source available has high salt concentrations. Hydroponics allows using these waters for production of various crops, including vegetables, however, the water salinity can cause nutritional disorders. Thus, two experiments were conducted in a greenhouse at the Department of Agricultural Engineering of the Federal Rural University of Pernambuco, to evaluate the effects of salinity on the mineral nutrition of crisphead lettuce, cultivar Taina, in a hydroponic system (Nutrient Film Technique), using brackish water in the nutrient solution, which was prepared by adding NaCl to the local water (0.2 dS m-1). A randomized blocks experimental design was used in both experiments. The treatments consisted of water of different salinity levels (0.2, 1.2, 2.2, 3.2, 4.2 and 5.2 dS m-1) with four replications, totaling 24 plots for each experiment. The water added to compensate for the water - depth loss due to evapotranspiration (WCET) was the brackish water of each treatment in Experiment I and the local water without modifications in Experiment II. The increase in the salinity of the water used for the nutrient solution preparation reduced the foliar phosphorus and potassium contents and increased the chloride and sodium contents, regardless of the WCET. Foliar nitrogen, calcium, magnesium and sulfur contents were not affected by increasing the water salinity used for the nutrient solution preparation.

title: Reviewing, twisting, reversing and resuming images: film communities and cosmopolitics

description: Abstract This paper observes communities of spectators in its actual appearance in films directed by (or in co-authorship with) indigenous groups. Indeed, this production (particularly within Video in the Villages project) shows that beyond of a method or procedure, exhibiting films for a unique community assumes the statute of a dispositive, which has not only cinematic implications but also cosmopolitical ones. In movies such as A arca dos Z’oé (1993), De volta à terra boa (2008), Pirinop – meu primeiro contato (2007), Tava – casa de pedra (2012) e Pele de branco (2012), “communities of cinema” are formed, integrating the mise-en-scène and forging a complex image, in which the group recognizes itself at discrepancy delaying.

title: In vitro evaluation of the sensitivity of strains ofStaphylococcus spp. isolated from goat mastitis against commercial disinfectants

description: The use of disinfectants in the prophylaxis of mastitis is a practice adopted in its control program. The use of post milking teat antisepsis (post-dipping) has been shown to reduce the rates of mammary infections by reducing the colonization by microorganisms on the skin of the teats. The aim of this study was to evaluate the in vitro susceptibility of 101 strains ofStaphylococcus spp. isolated from goat mastitis against four disinfectants: iodine 2, 1 and 0.5%, sodium hypochlorite 2.5, 1.25 and 0.62%, chlorhexidine 2.0, 1.0 and 0.5% and quaternary ammonia 0.68, 0.34 and 0.17%. It was found that all concentrations of disinfectants were effective for complete removal of the agent at the times of 30 and 60 minutes. We observed the following percentages of resistance to disinfectants: 15.8% to iodine in a 0.5% concentration; 10.8% to sodium hypochlorite (0.62%) and 7.9% to the quaternary ammonium (0. 17%). Chlorhexidine has demonstrated to eliminate 100% of the strains of staphylococci in vitro, at all times and concentrations tested, showing a broad spectrum of action without causing irritation to the skin of animals. As it provides a low cost disinfection, it becomes an economically viable product to be used in the goat mastitis control program.

title: evaluation of data acquisition methodology representing morphological features of sandy beach through digital elevation model

description: AbstractIn the northeastern coast of Rio Grande do Norte (RN), the coastal dynamicshas been analyzed trough the multitemporal comparison of Digital Elevation Models (DEMs) generated by geodesic method based on the position and on the GNSS altimetry in relation to the Brazilian Geodesic System.That analysis has made it possible to measure the short-term morphological changes (intrannual) in regional scale. In order to validate the reliability level of the geodesic methodology, a case study has been accomplished on Soledade beach, in Macau/RN, in which the geodesic method has been compared to the topographic one by measuring distances and angles, considered as references. During the qualitative analysis, it was observed that both models demonstrated enough sensibility to represent the beach morphological features of the studied area. Quantitavely, the differences between the orthometric altitudes in relation to the standard ones have had decimeter accuracy in both models in nine external control points, with an average of -0.244m for the topographic model and 1.139m for the geodesic pattern.

title: U-Pb zircon geochronology of intrusive and basement rocks in the Jacurici Valley region, São Francisco Craton, Bahia

description: ABSTRACT The Jacurici Complex, located in the NE of the São Francisco Craton, is constituted by several Cr-mineralized mafic-ultramafic N-S bodies, possible fragments of a single sill disrupted during deformation. Some works suggest it is intruded on the Serrinha Block while others consider it in the Salvador-Curaçá Belt. The basement on this region is informally divided into paragneisses and orthogneisses; the latter is supposed to be younger considering it is less deformed. Petrography revealed that some of the paragneisses are alkali-feldspar granite strongly milonitized. The orthogneisses occur at the north and consist, at least in part, of monzogranites with heterogeneous deformation, locally of low temperature. U-Pb zircon dating were performed for five representative samples. Just three provided good concordia ages. A mafic rock produced a 2102 ± 5 Ma age and it is petrographically similar to the metanorites described in the Jacurici Complex, being interpreted as the record of the first pulses of the mafic magmatism. A monzogranite yielded a 2995 ± 15 Ma age, older than expected, related to the Serrinha Block. The alkalifeldspargranite yielded a 2081 ± 3 Ma age. The Itiúba Syenite and the pegmatites that crosscut the JacuriciComplex have similar ages. Considering the lack of information about the supracrustal sequence that hosts the intrusive alkaline and mafic-ultramafic rocks at the Ipueira and the Medrado areas, it is possible that part of the terrain belongs to the Salvador-Curaçá Belt. We suggest that the Jacurici Complex could be intruded after the tectonic amalgamation between the Serrinha Block and the older part of the Salvador-Curaçá Belt and, therefore, could be hosted by both terrains.

title: Space time evolution of the trophic state of a subtropical lagoon: Lagoa da Conceição, Florianópolis Island of Santa Catarina, Brazil

description: ABSTRACT High levels of eutrophication in coastal lagoons due to human activity have been documented worldwide. Among the main impacts observed are anoxia, hypoxia, toxic algal blooms, fish kills, loss of biodiversity and loss of bathing. This study aimed to evaluate the evolution of the trophic state of Lagoa da Conceição, a subtropical lagoon located in an urbanized watershed on the island of Santa Catarina - Brazil. Spatio temporal patterns of stratification and eutrophication were investigated to understand the main biochemical changes over time. The water quality data were obtained from field campaigns supplemented with literature of the last 15 years. The vertical structure of the water column and the trophic state were evaluated by the stratification index and the TRIX index, respectively. Analyses of variance were performed in order to identify possible temporal variations in vertical stratification and trophic level. Eutrophication effects on biogeochemical cycles were verified through a multi-dimensional cluster analysis (MDS) and correlations between variables related to physical, chemical and biological processes were verified by principal component analysis (PCA). The results showed that the water column is homogeneous in all regions except in the central region of the lagoon, and the highest ammonia concentrations and lowest dissolved oxygen concentrations with periods of anoxia are observed in bottom waters. The study looked at the high trophic level of the lagoon and its inability to process the biogeochemical changes imposed by urban development.

title: NON-CARCASS COMPONENTS OF NELLORE BOVINES SLAUGHTERED WITH DIFFERENT WEIGHTS

description: AbstractThe objective of the experiment was to evaluate byproducts yield of non-castrated Nellore males slaughtered at different weights. Forty Nellore males with average weight of 350 kg at the beginning of the feedlot were used. In a completely randomized design, the animals were divided into four groups: 0 to 2-teeth animals with carcass weight up to 238.0 kg (young and light carcasses); 2-teeth animal with carcass weights ranging from 238.1 to 258.0 kg (young and middle weight carcasses); 2-teeth animal with carcass weight over 258.0 kg (young and heavy carcasses) and animals with four or six teeth, regardless of carcass weight (adults). Animals were fed during 84 days with diet calculated to reach average weight gain of 1.2 kg/day. Hide weight was higher for young and heavy animals in relation to young and light and adult animals. Regarding the non-carcass components yield, we verified difference for liver percentage, which was higher for young and heavy animals (1.91%) in relation to young with middle weight carcasses (1.49%). Economic analysis showed that the non-carcass components of young animals with heavy carcass result in higher income (R$ 208.00), followed by young animals with middle weight carcasses (R$ 193.56), and the incomes of adult and of young and light animals, respectively, R$ 21.42 and R$ 23.42 lower than the first one. No carcass components add to industry from R$ 0.71 to R$ 0.80 per carcass kilogram.
