title: Astronomy as a playful tool for physics teaching: kinetic theory of gases through star clusters

description: Abstract This interdisciplinary work proposes to use astronomical objects as a ludic tool to arouse student's curiosity, provide opportunities and enhance the teaching-learning process in Physics II and Statistical Mechanics classes. Its purpose is to discuss whether the Maxwell-Boltzmann velocity distribution law for ideal gases also describes the behavior of star velocities in star clusters. For this, the student's investigative thoughts it will be triggered by star velocity data, obtained through observations from the Blanco telescope and KPNO (Kitt Peak National Observatory), provided in the literature for the Omega Centauri globular cluster and the Pleiades open star cluster. It can be concluded that in dynamically relaxed globular clusters, although physically very different from ideal gases, stars follow Maxwell-Boltzmann's law of velocity distribution. This is because, in fact, any classical many-body system that satisfies the two assumptions used in the computations of velocity distribution will satisfy the Maxwell-Boltzmann distribution, regardless of whether the interaction between the bodies is of short or long-range and whether they are microscopic or macroscopic objects. Thus, by demonstrating that star clusters follow ideal gas-like laws, it became possible to use the ludic of astronomy to encourage students in the process of learning the content of the kinetic theory of gases.

title: Concurrent validity of handgrip strength between the jamar and bulb dynamometers in women with rheumatoid arthitis

description: Abstract Introduction: Rheumatoid arthritis (RA) is a progressive disease that causes deformation and constant joint damage. Handgrip strength (HGS) has been used by several health professionals in clinical practice as a mechanism for assessing muscle strength and overall performance. Objective: To perform the concordance analysis of handgrip strength measurements using a pneumatic dynamometer (Bulb) and a hydraulic dynamometer (Jamar) in women with rheumatoid arthritis. Method: The HGS measurements by the two dynamometers followed the norms of the American Society of Hand Therapists. The concordance between measurements was performed by the Bland-Altman method. Significance level was 5%. Results: In total, 41 women (60.63 ± 8.35 years) participated in the study. Analysis showed that the measures between the two dynamometers were not concordant (bias = 9.04, p &lt; 0.01), there was a linear relationship between the difference of the measures and the mean (r = 0.73, p &lt; 0.01), and the limits of agreement were very extensive (−2.74 to 20.81). Conclusion: Assuming that the rheumatoid arthritis compromises the hands, with a consequent decrease in HGS, further exploration of the subject is suggested in future studies to define the best measure for clinical practice at the different levels of health care. However, since there are many different dynamometers, we suggest to better explore the agreement between the measurements obtained by them in populations under different conditions.

title: Analysis of records by nursing technicians and nurses in medical records

description: ABSTRACT Objectives: to analyze the main non-conformities of the nursing records of a public hospital in Natal, Brazil. Methods: this is a descriptive, cross-sectional study, with a quantitative approach. This study was conducted in nursing departments of medical and surgical wards. The sample was composed of 120 medical records of inpatients between October and December 2016. The obtained data were tabulated and analyzed by simple statistics in absolute and relative frequency using the 2013 Microsoft Excel software. The Pareto Diagram was used to evaluate the non-conformities of the records. Results: the main problems in the nursing records were the absence of the professional category and the nursing council number, responsible for 41.8% of the non-conformities in the records of nursing technicians; for nurses’ records, the main non-conformities were the absence of time and the illegible handwriting, with 61.2%. Conclusions: the study showed that nursing professionals perform their records incompletely and often do not document the care provided.

title: Predictive model of hospitalization for children and adolescents with chronic disease

description: ABSTRACT Objectives: Describe a predictive model of hospitalization frequency for children and adolescents with chronic disease. Methods: A decision tree-based model was built using a database of 141 children and adolescents with chronic disease admitted to a federal public hospital; 18 variables were included and the frequency of hospitalization was defined as the outcome. Results: The decision tree obtained in this study could properly classify 80.85% of the participants. Model reading provided an understanding that situations of greater vulnerability such as unemployment, low income, and limited or lack of family involvement in care were predictors of a higher frequency of hospitalization. Conclusions: The model suggests that nursing professionals should adopt prevention actions for modifiable factors and authorities should make investments in health promotion for non-modifiable factors. It also enhances the debate about differentiated care to these patients.

title: POLITICAL TOLERANCE IN RECENT BRAZIL: evolution of indicators and conditioning factors

description: Combining public contestation with political participation, democracy is equally dependent on an environment of political tolerance. A quality democracy could not exist in an environment marked by strong intolerance, in which people do not have the opportunity to express their opinions and debate their ideals. This conditionality imposes difficulties for the process of improving Brazilian democracy, especially considering the troubled past years. The current political crisis, which began with the protests that culminated in the impeachment of President Dilma Rousseff and has not yet ended, has been marked by strong contentiousness and manifestations of intolerance by the different parties involved in the dispute. Given this scenario, this article presents a framework of political tolerance in recent Brazil. Using the Latin American Public Opinion Project’s (LAPOP) historical data series, we analyze the evolution of different indicators of politically tolerant attitudes and, beyond these general contours, explore possible socio-demographic, attitudinal and behavioral determinants. The data indicate that in all indicators, the opinion of Brazilians tends to be mostly tolerant for the set of measures adopted, however, there was a decline in all of them when observing the 2014 survey. Regarding the determinants of tolerance, we found evidence that such attitudes are related to higher levels of voter cognitive mobilization.

title: Professional who attended childbirth and breastfeeding in the first hour of life

description: ABSTRACT Objectives: To investigate the association between the professionals who attended vaginal delivery and breastfeeding in the first hour of life. Methods: This is a cross-sectional study with data from the Nascer no Brasil (Born in Brazil) survey, conducted in the 2011-2012 period. Data from 8,466 puerperae were analyzed using a logistic regression model with a hierarchical approach. Results: The proportion of mothers who breastfed at birth was higher in deliveries attended by nurses (70%). A nurse-assisted delivery was 64% more likely to breastfeed in the first hour of life. Other factors associated with the outcome: residing in the North; age less than 35 years; multiparity; prenatal guidance on breastfeeding in the first hour of life; birth at Baby-Friendly Hospital; companion at birth; and female newborn. Conclusions: Obstetrician nurse/nurse-assisted delivery was a significant independent factor associated with breastfeeding in the first hour of life, suggesting the importance of strengthening the role of the obstetrician nurse.

title: INFLUENCE OF DRAINAGE METHODS ON SOYBEAN DEVELOPMENT IN LOWLANDS

description: ABSTRACT The need for crop rotation and profitability in lowland areas are the two main reasons for the introduction of soybean cultivation in the state of Rio Grande do Sul, Brazil. These areas have poor natural drainage, which impedes proper soybean growth. In this sense, this study aimed to assess the efficiency of using broad base ridges in comparison to the surface drainage for soybean cultivation in lowlands. The study was conducted during the 2014/2015 and 2015/2016 growing seasons in São João do Polêsine, RS, Brazil. The assessed drainage methods were the use of broad base ridges with different width dimensions (22.5, 15.0, and 7.5 m) and surface drainage. The results showed that the shoot dry matter and leaf area index have similar behavior. The broad base ridge was better than the surface drainage method for these variables. The 7.5-m broad base ridge stood out among the treatments when compared to the others, as it had the best results for the leaf area index (8.66), plant height (102.5 cm), and shoot dry matter (33.06 g).

title: Effects of coexistence of marketing and operations on product innovation performance

description: Abstract: The present study aimed at investigating the impact of the coexistence of marketing and operations on product innovation performance in the flexible plastic packaging industry in Brazil. To this end, the study was conducted in two stages: one, exploratory and qualitative, and the other, descriptive and quantitative. In the first stage, a construct was chosen and validated to identify the effect of integrating the functions of innovation and develop an instrument for data collection. In the second stage, we defined the research population, collected data, and performed statistical analysis of the results. To measure the relationship of marketing and operations, we used a theoretical construct which investigates the level of integration in the four phases of the new product development process and innovation performance, considering both financial and non-financial dimensions. Data were collected through a structured questionnaire and statistically analyzed through linear regression and correlations between variables. The results showed that the integration of these areas has a positive and significant impact on the success of innovation, indicating that information-sharing in the initial and final stages of the product innovation process is a driver for achieving better performance. One of the main findings of this study is that, in isolation, the field of marketing does not perceive the impact of the integration of functions on innovation.

title: Do local environmental factors structure the trophic niche of the splash tetra, Copella arnoldi? A test in an Amazonian stream system

description: ABSTRACT Environmental variation affects the availability of spatial and trophic resources in Amazonian streams and may be important factors structuring the diet of fishes. We analyzed the diet composition and trophic niche breadth of the lebiasinid splash tetra, Copella arnoldi, aiming to evaluate how environmental variation in Amazonian streams affects the species’ trophic niche. Fish were captured and environmental factors were recorded in 20 streams in the Caxiuanã National Forest, in the eastern Amazon, in November 2010. We made a semi-quantitative analysis of stomach contents of 200 individuals. Copella arnoldi exhibited an omnivorous diet composed mainly of detritus and allochthonous invertebrates. Environmental variation (stream width, stream depth, canopy cover and flow) did not affect the diet composition or trophic niche breadth of the species, possibly due to the regional integrity of the forest within the boundaries of the protected area. Riparian cover probably minimizes the effect of the small-scale variations in food resources, thus leading to a locally homogeneous diet composition in the splash tetra C. arnoldi.

title: Sampling of cashew nuts from cashew tree clones

description: Abstract The aim of this work was to estimate sample sizes to assist the genetic improvement of the cashew tree (Anacardium occidentale L.). Stratified sampling, comprising five strata (S5, S4, S3, S2, and S1) of five cashew clones (BRS 274, BRS 275, BRS 226, BRS 189 and CCP 76), was effective for estimating the different sample sizes of the nut. Sample size for each clone depends on the weight-nut variance, the margin of error B permitted in the estimates and the desired precision of the results. The increases in sample size with clone variance, lowered the permitted margin of error B, and increased the desired precision of the results. These clones required different sample sizes for a morphological study of the nuts. Larger nuts require larger samples for the same margin of error B. For an error B of 0.2g, the sample size for clones S5, S4 and S3 were n5 = 84, n4 = 49 and n3 = 37 nuts. For clones BRS 274 (S5) and BRS 275 (S4), with better nut classification, the mean weights were respectively 16.79 and 12.78g. Clones BRS 189 (S2) and CCP 76 (S1), with smaller nuts, have a smaller variances, s22 = 0.7638 and s12 = 1.0712, where the mean weight was 8.29 and 7.81g respectively.
