title: Composition, density and biomass of fish community from the surf zone as a function of the lunar cycle at Miramar Beach in Cabedelo, Paraíba

description: ABSTRACT The influence of the moon cycles on the ichthyofauna has been little studied in the surf zone. In this study, the number of species, density and biomass were evaluated as a function of the moon. A total of 49 species distributed in 24 families were captured in two areas of Miramar beach. The mean density was significant high in the weaning and low in the new moon, while density and biomass together showed differences for areas. The most abundant species were Anchoa tricolor and Trachinotus falcatus (new moon), and Anchovia clupeoides showed significant differences in the waning moon. The RDA indicates that turbidity influenced significantly the presence of two species group. The group I were represented by Stellifer brasiliensis, Trachinotus goodei, A. clupeoides, Chilomycterus spinosus and Conodon nobilis that occurred on the waning and new phases in both areas, while the group II were represented by Polydactylus virginicus and Haemulopsis corvinaeformis in the full moon. The surf zones may also be strongly governed by the lunar phases. Therefore, the results found in this study, showed that the biological interactions between the species with turbidity and moon might explain the density and biomass variations for some species in the surf zone.

title: A Temporal Model of Perceived Control to Explain Service Failures

description: Abstract Research on service failure has neglected the temporal dimension of consumer-perceived control (i.e., past, present and future control). This paper introduces the temporal model of perceived control to service research and compares its explanatory power for consumers’ emotional and behavioural reactions after a service failure to that of the causal attribution model. The results of a correlational study show that the temporal model of perceived control has greater explanatory power than the causal attribution model (i.e., the former can better predict consumers’ regret, self-focused anger, and repurchase behaviour after a stressful service episode). This is the first empirical research to use a temporal model of perceived control to explain consumer reactions after service failures, showing that this model may be combined with others in a complementary way to provide a better understanding of consumer reactions.

title: Acquisition and completion of pregnant woman's medical booklet in four populational-based surveys

description: Abstract Objectives: to measure the prevalence of acquiring and evaluating the level of completion of the pregnant women's medical booklet on the occasion of childbirth in Rio Grande, Brazil. Methods: this is a cross-sectional study including all puerperals residing in this municipality in 2007, 2010, 2013 and 2016. The mothers were interviewed at the only two local maternities up to 48 hours after childbirth. The data from the pregnant woman’s medical booklet were copied on a standard form. The chi-square test was used to compare proportions. Results: 10,242 pregnant women were included in this study. Of these, 54.8% (CI95%=53.8%-55.7%) had their pregnant woman's medical booklet with them at the time of admission. The completion pattern of the pregnant woman's medical booklet is divided into three groups, namely: with at least 95%: date of the last consultation visit, maternal height and blood pressure verification, uterine height, cardio-fetal heart rate and the Rh factor; 85% or more: date of the last menstruation, qualitative urine test, VDRL and HIV; and less than 30%: performance of clinical breast examination and cytopathology of the uterine cervix. In the private sector, the acquisition of the pregnant woman's medical booklet was 41% lower than at the public sector (62% vs. 44%). Conclusions: the use of the pregnant woman's medical booklet and its completion were lower than expected on several items. Local managers need to work together with the health professionals and these health professionals should work with the mothers to promote the full use of this essential document for the maternal and child's health.

title: ASSESSMENT OF POLYHYDROXYALKANOATE SYNTHESIS IN SUBMERGED CULTIVATION OF Cupriavidus necator AND Burkholderia cepacia STRAINS USING SOYBEAN AS SUBSTRATE

description: ABSTRACT Polyhydroxyalkanoates (PHA) are biocompatible and biodegradable polyesters produced by prokaryotic microbes for energy storage and carbon reserve. These polymers are an option to diminish the massive impact caused by inadequate disposal of synthetic plastics. In this study, evaluation and characterization of PHA produced by Cupriavidus necator (IPT 026 and IPT 027) and Burkholderia cepacia (IPT 119 and IPT 400), using soybean as substrate, were carried out (soybean 15 g L-1, pH 7.0, 150 rpm, 72 hours). The highest polymer production was achieved using IPT 027 (0.84 ± 0.07 g L-1). All PHA produced showed the characteristic bands of polyester functional groups in the FTIR spectra. Polymers synthesized by Cupriavidus necator exhibited initial temperatures of degradation superior to 300oC and higher molecular weights than the ones produced by Burkholderia cepacia, which in turn, exhibited lower crystallinity (inferior to 30%), revealing high influence of the microorganism strain on PHA properties and production.

title: Influence of Zirconia-Coated Bioactive Glass on Gingival Fibroblast Behavior

description: Abstract The objective of this study was the development of a bioactive glass coating on zirconia (Zr) to modulate the gingival fibroblast phenotype. For this purpose, Biosilicate® (BS) particles in a water/isopropyl alcohol (1:1) vehicle (6 mg/mL) were applied to zirconia discs followed by thermal treatment at 1100 °C for 20 min. The surface topography (SEM), chemical composition (EDX), surface roughness (Ra; confocal microscopy), surface free energy (goniometry), and color alteration (UV-vis spectrophotometry) were assessed (n=6). Thereafter, L929 fibroblasts were seeded onto Zr and Zr+BS discs, and cell proliferation (Alamar Blue; n=6), morphology (SEM; n=2), migration (wound healing; n=4), and collagen synthesis (Sirius Red; n=6) were evaluated up to 7 days. Data were analyzed by ANOVA/Tukey tests (a=5%). A homogeneous coating consisting of Si, Na, O, and Ca was detected on the Zr surface after thermal treatment with BS, which led to a significant increase in surface roughness and free energy (p&lt;0.05). No change in color parameters was observed (p&gt;0.05). Cells seeded on the Zr+BS surface featured increased proliferation, collagen expression, and migration capability in comparison with those cultured on plain Zr (p&lt;0.05). SEM images revealed that cell spreading occurred faster in the presence of BS. Therefore, it was concluded that thermal treatment of the Zr surface with BS led to the deposition of a bioactive coating, which induced gingival fibroblast spread, proliferation, migration, and collagen expression in vitro.

title: Production and quality of grafted watermelon in saline soil

description: ABSTRACT Salinity of soil in arid and semiarid regions is a problem that affects the production and quality of fruit. That’s while we evaluated grafting on watermelon plants as an alternative to reduce the salinity effects. The experimental design was of randomized blocks, three treatments (cultivars Sangria, Summer Flavor 800 and Summer Flavor 840) with three repetitions. The cultivars were evaluated in grafted and ungrafted condition. The rootstock used for grafting was the interspecific hybrid Strong Tosa (C. maxima x C. moschata). In average terms for the three cultivars, grafting increased commercial production, weight, length and diameter of fruits in 160.5%, 36.5%, 12.0% and 7.5%, respectively. Sangria presented the best answer in production with 57.1 t ha-1, weight 5.8 kg, length 35.0 cm and diameter 17.8 cm of fruits. Also, grafting favored in 6.3% the luminosity and reduced 6.4% Hue angle. Summer Flavor 840 showed the best result in luminosity with 48.3 and hue angle 26.4°. Firmness, °Brix and lycopene content were not modified by grafting. Grafting represents an alternative for watermelon production in saline soils, improving yield and quality of the fruits.

title: Shrinkage and porosity in concretes produced with recycled concrete aggregate and rice husk ash

description: Abstract The admixture of recycled concrete aggregates (RCA) in new concretes is an interesting alternative in the efforts to mitigate environmental impacts. RCA may increase porosity and change properties of concretes. Rice husk ash (RHA) is employed as supplementary cementitious material may improve concrete properties. The present study investigated the shrinkage of concrete prepared with RCA and RHA, proposing a mathematical model to explain the phenomenon. Concretes were produced with 25% and 50% of coarse recycled aggregate as replacement of natural aggregate, 0%, 10%, and 20% of RHA as replacement of cement, and a water-to-binder ratio of 0.64. Water absorption and capillary and total porosities were analyzed on day 28. Shrinkage tests were conducted on days 1, 4, 7, 14, 28, 63, 91, and 112. The results point to a significant interaction between RHA and RCA.

title: Biochemical descriptors: importance of the genetic divergence study in peppers

description: ABSTRACT The genetic diversity of pepper genotypes is usually evaluated based on morphological and molecular descriptors. However, studies using biochemical descriptors of peppers are still incipient. Thus, the objective of this study was identify biochemical descriptors of Capsicum spp. with antioxidant action, most responsive to the selection of superior genotypes, and evaluate the correlation between concentrations of the parameters using principal components analysis. The experiment was conducted in the city of Cáceres, southwest Mato Grosso, Brazil. Seventy-eight pepper accessions from the Active Germplasm Bank of UNEMAT were planted in randomized block design. The harvested fruits were immersed in liquid nitrogen for two minutes, and the following biochemical analyses were performed: titratable acidity, ascorbic acid, total phenols, flavonoids, anthocyanins, carotenoids, chlorophyll a, chlorophyll b, and antioxidant activity. Biochemical descriptors that best estimated the genetic variability of the accessions were flavonoids, total phenols, chlorophyll a, and ascorbic acid. Chlorophyll a and chlorophyll b were the compounds that showed the highest degree of correlation. Except chlorophyll a with ascorbic acid, all other vectors showed correlation ranging from moderate to strong.

title: Revisitando a Mobilidade Intergeracional de Educação no Brasil

description: Abstract In this article we present recent evidence about intergenerational mobility in Brazil. We verified that the degree of educational persistence has decreased substantially since the 1990s, for all regions, races and household situations. This is explained by the increase in educational attainment of the children of the schooled parents and by the stabilization of educational attainment of the children of more schooled parents around 11 years of schooling. Despite this, mobility is still lower for the children of less schooled parents. Finally, we report an increase in educational mobility among younger generations.

title: Effects of Future Expectations on Organizational Commitment and Intention to Leave

description: Abstract Expectations are a relevant part of working life, but their effect on other variables in the field of organizational behavior remain poorly explored. Thus, this research tested a model in which organizational future expectations and career expectations in the organization acted as antecedents of affective organizational commitment and intention to quit. Professionals from several organizations (n=370) answered scales validated in Brazil. Organizational future expectations were related to affective organizational commitment and career expectations in the organization. The latter variable acted as an antecedent of affective organizational commitment and intention to quit. The organization’s sector and the future expectations of the participants act as moderates in the model. The discussion analyzes the temporal dimension of the individual-organization relationship and its importance to human resource management.

title: Isoflavone, anthocyanin, and fatty acid contents of vegetable-type soybean grains at different maturity stages

description: Abstract: The objective of this work was to determine the oil, protein, fatty acid, isoflavone, and anthocyanin contents in soybean grains of different breeding lines and maturity stages. Evaluations were performed for the chemical profiles of black- (BRM09-50995) and of yellow-seed-coat (BRM11-51428 and BRM08-50643) breeding lines, harvested at the R6 (immature seeds), R7 (physiological maturity), and R8 (full maturity) maturity stages. Oil and protein contents increased from the R6 to the R8 stage, and BRM11-51428 showed the highest protein content. Palmitic, stearic, and linolenic fatty acids were higher at R6, and linoleic and oleic acids were higher at R7 and R8, respectively. At the R8 growth stage, BRM11-51428 and BRM 09-50995 showed the highest contents of oleic and linoleic acids, respectively, and the lowest content of linolenic acid. The amounts of isoflavone glucosides and aglucones were higher at R8, while malonyl forms were higher at R7. Total aglucones increased about three times from R6 to R8. BRM09-50995 showed the highest content of total isoflavones and anthocyanins, mainly at the R8 stage, which makes this lineage an option to process functional soybean food.

title: Prosthesis-Patient Mismatch after Surgical Aortic Valve Replacement: Neither Uncommon nor Harmless

description: Abstract Prosthesis-patient mismatch (PPM) after surgical aortic valve replacement (SAVR) is an issue that has been overlooked (not to say neglected). Cardiac surgeons must bear in mind that this is a real problem that we must tackle. The purpose of this paper is to be a wake-up call to the surgical community by giving a brief overview of what PPM is, its incidence and impact on the outcomes. We also discuss the increasing role played by imaging for predicting and assessing PPM after SAVR (with which surgeons must become more acquainted) and, finally, we present some options to avoid PPM after the surgical procedure.
