title: Social Security: reform or are there alternatives?

description: Abstract The situation of Social Security in Brazil has been widely questioned, mainly due to the proposal of the Constitutional Amendment 287/2016 that is processed in the National Congress. Given that the reform will create barriers to the access to social security benefits, the main objective of this study is to find out if the reform is indispensable to the continuity of Social Security or if there are alternatives without having to make such radical changes. In order to seek clarification on the existence or not of the deficit, we identified the different calculation methods used in the measurement of financial results of welfare and Social Security. Based on the conclusions, it is shown that the system is not deficient and that, initially, other measures should be adopted. The reason for this being that since the enactment of the Federal Constitution of 1988, the reforms have not proved enough to stop the government from using the discourse of the “unsustainability” of this system.

title: Presence of ascites in bullfrog breeders reared and kept on a frog farm

description: ABSTRACT Ascites is a pathology characterized by the extravasation of fluid from blood vessels and its accumulation in the abdominal cavity, caused by several associated factors. In this paper, we report the occurrence of this syndrome in breeding male and female Bullfrogs fed a commercial fish feed with 40% crude protein. Liver malformation was already observed due to lack of protein deposition in adult animals from the same spawning. The culture of ascitic fluid showed absence of bacterial growth. Kidney histopathology showed, in both sexes, a large number of tubular structures with strongly eosinophilic hyaline material suggesting colloid growth in both the cortical region and spinal cord. The analysis also revealed granulomas in various stages of development, many showing central necrotic material. The kidneys, glomerular, were mostly hypoplastic, with enlarged Bowman space, and many were hyalinized or hemorrhagic; the parenchyma showed dystrophic calcification, and many tubules containing fibrinoid material. The liver displayed a large amount of melanomacrophages in the parenchyma and foci of mono-lymphocytic hepatitis and marked cytoplasmic rarefaction, as well as several hepatocytes with pyknotic nuclei and necrotic cells and dissociation of the hepatic trabeculae. Ascites may be caused by the lesions observed in these organs.

title: Association of organized physical activity and levels of cardiorespiratory fitness with indicators of mental health in children

description: Abstract Aim: To verify the associations between organized physical activity out of school (PA) and cardiorespiratory fitness (CRF) with indicators of mental health in children. Methods: This is a cross-sectional study, with a sample of 226 students (47% girls) of public school in the south of Brazil aged between 6 to 11 years-old (8.36 ± 1.46). The cardiorespiratory fitness was measured by running and walking-test in six minutes, following the procedures of the “Brazil Sports Project”. PA was evaluated through a question and the Strengths and Difficulties Questionnaire assessed mental health indicators. Generalized linear regressions were used with a confidence interval of 95%. Results: Total difficulties (β = 2.691; 95%CI, 0.181 to 5.200) and emotional symptoms (β = 1.528; 95%CI, 0.609 to 2.448) were inversely associated with PA. Total difficulties (β = -0.013; 95%CI, -0.022 to -0.003), hyperactivity/attention deficit (β = -0.002; 95%CI, -0.010 to -0.002), and peer relationship problems (β = -0.002; 95%CI, -0.003 to -0.001) were associated with CRF in boys. Conclusion: A total of difficulties and emotional problems presented an inverse association with PA. Further, CRF was inversely associated with total difficulties, hyperactivity-inattention, and peer relationship problems.

title: The Surface Treatment of Niobium Superconducting Reentrant Cavities by Means of High Temperature Nitrogen Plasma Based Ion Implantation

description: High Temperature Nitrogen Plasma Based Ion Implantation (HT-NPBII) has been used to treat the surface of niobium superconducting reentrant cavities, which are part of parametric transducers in a resonant-mass gravitational wave detector. The aim is to enhance the corresponding electrical quality factors (Q-factors) which are closely related with the increase of the sensitivity of the system. In this experiment, the cavities are immersed in plasma and bombarded by energetic nitrogen ions, which are implanted into the surfaces of these heated substrates. The heating temperature of the cavities is controlled during the treatment and its level directly affects the N implantation depth profile due to the diffusion process. Additional tailoring of the nitrogen doping can be performed by the adjustment of the intensity and the duty cycle of the high negative voltage pulses used for ion implantation. For implantations performed at 5 kV /20 µs /300 Hz/ 700 °C, nitrogen atoms occupy interstitial spaces in the crystal lattice of niobium. The treatment of niobium superconducting cavities under these parameters caused the enhancement of two orders of magnitude of respective Q-factors. A set of characterization techniques was performed herein in order to help with the understanding of the underlying mechanism behind this phenomenon.

title: Ingestive behavior of heifers in sorghum implanted with different population arrangements

description: ABSTRACT The objective of the study was to evaluate the effects of sorghum pasture implantation with different population arrangements in animal behavior and pasture structure and their relationships. The treatments were the combination of two row lines and two seeds per hectare densities, 22 or 44cm between rows and 12 or 24kg ha -1 of seed. 36 heifers at 15 months of age and 262kg body weight were used. The E44D24 and E22D12 treatments showed higher time of grazing (469.33 and 467.78 minutes, respectively). The animals in E44D24 treatment had lower bit rate (23.99 bites minute -1 ) compared to treatment with E22D24, a higher bit rate (32.45 bits min -1 ). The animals in E44D12 treatment presented the largest number of stations minute -1 (9.21) and higher displacement rate (11.76 steps min -1 ). The row spacing of 22cm increases the number of bits station -1 . The increase in seed density and the use of larger planting row spacing’s increase the leaf density of the lower (0-30cm) and higher stratum (above 60cm) of pasture. The E44D12 and E22D24 treatment have higher amounts of stems in the upper stratum of the pasture.

title: Hypertension and maternal urinary tract infection and the metabolic conditions of preterm infants

description: ABSTRACT Objective: The present study evaluated the anthropometric and metabolic profiles of preterm infants (PT) born from mothers with urinary tract infections (UTI) and mothers with hypertensive disorders (HD). Method: This was a longitudinal prospective study conducted between May 2015 and August 2016. First, 59 mothers with premature birth were included; after excluding 29 mothers, two subgroups were created: UTI-mothers (n=12) and HD-mothers (n=18). The anthropometric and metabolic variables of mothers and their respective PT were analyzed at birth and at 6 months of corrected age (CA). Results: Plasma triglyceride levels were higher among HD-mothers and their respective PT in comparison with UTI-mothers and their PT at 6 m of CA. Conclusion: Plasma triglyceride level is an important metabolic biomarker in HD-mothers resulting in higher triglyceride levels among PT at the CA of 6 m, suggesting an early programming effect of maternal hypertension.

title: Revised formula for predicting the long-term deflection multiplier of normal and high strength concrete

description: Abstract High strength concrete (HSC) has found many applications in civil engineering structures such as in high-rise buildings, and bridges. The mechanical properties of HSC are sometimes different than of normal strength concrete (NSC). In particular, HSC possess lower creep strains compared to NSC. As a result, members constructed using HSC have been found to deflect less under sustained long-term loads. However, formulas used by current codes of practice such as ACI (318) code and Australian standard (AS-3600) for predicting the long-term deflections don’t account for effects of HSC. This study aims to present a theoretical formula to calculate the long-term deflections for reinforced concrete beams made from NSC and HSC, taking into account the influence of HSC. The formula was derived from curve fitting analysis of long-term deflections obtained from several experimental tests available in literature. The presented equation considers the effects of several factors, such as compressive strength of concrete, and reinforcement at compressive zone, found in the experiments to have a significant impact on long-term deflections. The results of the equation were compared with experimental results of other researchers, and a good agreement was obtained. Following a parametric study, the long-term deflections were found to decrease to about 50% when increasing the concrete’s compressive strength from 20 to 100 MPa. The compressive steel reinforcement was found less effective in the case of HSC.

title: Assessment of feedback for the teaching of nursing practice

description: ABSTRACT Objective: to analyze the self-reported knowledge of professors in the use of feedback in the teaching of nursing practice; train professors to use this process; and evaluate the results of this training. Method: a qualitative study of research-action type. The focus group technique was used with seven collaborators of a nursing technical school. For content analysis, the Bardin framework was used and, for intervention, the Problematization Methodology supported by Pendleton’s Rules. Results: most present in their curricula training to teach. It is pointed out that feedback is a simple and essential assessment tool, although universal discourse does not express the exact dimension of feedback potentialities. The intervention was effective to solidify feedback. Final Consideration: this study shows that feedback should be disseminated and consolidated among the teaching staff of nursing technical education.

title: Influence of the social context in smoking during pregnancy

description: ABSTRACT Objective: to know the social and family relationships of pregnant women and to analyze their influence in keep smoking during pregnancy. Method: it is a descriptive-exploratory study with a qualitative approach, which had as subjects 10 pregnant smokers. Data were collected from January to March / 2015, through interviews, and organized into graphical representations of the genogram/ecomap and discourse units. Results: pregnant women had low educational level, precarious insertion in the work market and relations of great dependence of the family. Tobacco consumption integrates the family environment and is viewed naturally in the sociocultural environment. In prenatal care, there was no coordinated and longitudinal intervention for smoking cessation. Conclusion: smoking cessation is strongly influenced by the social environment, and the family is an important component of this network. In this sense, strategies to approach smoking should allow a reflection of the norms and rules of the family.

title: Hammock and nesting in preterm infants: randomized controlled trial

description: ABSTRACT Objective: To compare the physiological variables and the sleep-wake pattern presented by preterm in nesting and hammock positions after diaper change. Method: This is a crossover randomized controlled trial. It was conducted with 20 preterm infants who, after diaper change, were placed in nests or hammocks. These preterm infants were evaluated for physiological variables (heart rate and oxygen saturation) and behavioral variables (sleep and wakefulness). Results: There was no statistically significant difference in the studied variables between nesting and hammock positions. However, regarding the categorical variable sleep, the comparison between the research phases for the hammock position showed differences between the baseline phase and the immediate recovery (p=0.00), baseline and late recovery (p=0.00), response and immediate recovery (p=0.00), response and late recovery (p=0.00). Conclusion: No differences were identified between the nest and the hammock; however, the use of the hammock favored the sleep of preterm infants compared to its non-use.

title: Genotype by environment interaction and adaptability of photoperiod-sensitive biomass sorghum hybrids

description: ABSTRACT Biomass sorghum is an alternative feedstock to cogenerate energy and produce second-generation ethanol. The aim of this study was to evaluate the Genotype by Environment Interaction (GEI) in biomass sorghum and to identify the hybrids that associate high adaptability and stability using the Toler nonlinear regression, the Genotypes plus Genotype by Environment (GGE) biplot, and the Annicchiarico recommendation index. Thirty-three experimental photoperiod-sensitive single-cross hybrids and three checks were evaluated in relation to the traits: flowering time, plant height, moisture content, green mass yield, and dry mass yield. It was observed that the effects of hybrids, environment, and GEI were expressive. The GEI was predominantly complex for the traits related to the biomass yield. The Toler, GGE biplot and Annicchiarico methods show complementarity. The experimental hybrids 1, 8, 22, 31 and 33 are promising because of associating stability and lower recommendation risk. The hybrids 1 and 8 present broad adaptability, while the hybrids 22, 31 and 33 exhibit specific adaptability to high quality environments.

title: Looking for consensual protection categories to reduce conservation conflicts in protected áreas

description: ABSTRACT: Decision-making in protected areas is often difficult due to an unclear definition of management objectives and indicators for their monitoring. This is frequently related to the coexistence of systems of protected areas at national and regional levels for which management objectives are ambiguous or that are not directly related to protected areas classification standards. In this study, we proposed a participative model based on PROMETHEE II to find consensual protected areas categories based on IUCN framework. This model involved the stakeholder’s assessments of management objectives in a protected area and their aggregation based on distance comparisons with objectives of international protected areas standards. The model was tested in the Albufera de Valencia Natural Park, a strongly human-modified wetland located in Eastern Spain and it allowed the identification of consensual management priorities and the IUCN category V as the equivalent international protected area category for this regional protected area.
