title: Allometric models to biomass in restoration areas in the Atlantic rain forest

description: ABSTRACT The objective of the study was to present mathematical models and strategies for fitting equations to estimate dry biomass for tree species in forest restoration areas. The presence of outliers was analyzed in each fitted equation using values of the matrix H, leverage points, means of standard and studentized residuals, and of influential points through DFFITS, DFBETAS and COOK distance values. Furthermore, the normality, homoscedasticity and independence of residuals were checked. The accuracy of the fitted equations was evaluated by means of the R2adj., Syx, analysis of residuals, and AIC and BIC criteria. The results showed that the model for estimating dry biomass as a function of the variables Dc2, DBH2, Hc2 and DBH provides the more accurate solution, with Syx = 40.91% and R2adj. = 0.92. We concluded that the performance of this equation improves when adjusted to data stratified by classes of height-diameter ratio, which reduces the value of the estimated error.

title: CARDIOPULMONARY AND BLOOD GAS PARAMETERS IN SHEEP UNDER INHALATIONAL ANESTHESIA DURING DECUBITUS ALTERNATIONS

description: Abstract Sheep herds, especially Santa Ines breed, have grown in the Brazilian Midwest in recent years. Therefore, clinical cases have also grown, and along came the need of conducting major surgeries without pain associated with the use of inhalational anesthesia. This study evaluated the cardiopulmonary and blood gas parameters in sheep under inhalational anesthesia with controlled ventilation, and assessed the effect of decubitus alternations on the parameters. The animals were anesthetized with acepromazine and propofol, intubated and placed on inhalational anesthesia with isoflurane. The respiratory rates, blood pressure and blood gas concentrations were measured every for minutes for a total of 45 minutes during which the animals were alternated right, dorsal and left decubitus. The measured parameters showed no significant differences among the times and positions, concluding that inhalational anesthesia with isoflurane is valid and safe for sheep, as it keeps the cardiopulmonary parameters and arterial blood gases at safe levels.

title: Simulation of tailings release in dam break scenarios using physical models

description: Abstract This article presents an experimental study performed to evaluate the volume of material released from the reservoir during a tailings dam failure event using models. To verify the influence of the parameters related to the breach geometry and the undrained shear strength (Su) in a failure event, 20 scenarios were simulated considering the absence of water in the reservoir. The material used to simulate tailings was bentonite, due to the similarity between the properties of the mud and mineral tailings sludge. Geometry and undrained shear strength were adjusted considering a scale factor of 1: 500. Regarding the studied parameters, the geometry of the breach was based on data from literature, whose lateral slopes were 0.50 H: 1V, 0.51 H: 1V and 0.5467 H: 1V in the trapezoidal breaches and 1: 1 (L / H = 0.97) and 1: 1 (L / H = 1.1) in the rectangular ones. The undrained shear strength ranged from 0.030 to 0.20 kPa. The results allowed to conclude that the mobilization of material increases with the average aperture width of the trapezoidal breach, being this the distinct behavior in rectangular breaches. Although the rectangular breaches had smaller average widths compared to the trapezoidal breaches, their base widths were larger and it is possible to infer that the mobilized volume depends on the geometry and the average width of the breach.

title: Research ethics committees in Brazil: a study with coordinators

description: Abstract This study aimed to characterize the Research Ethics Committees in their profile and operationalization. An electronic questionnaire was sent to the 645 existing committees at the time and answered by 129 coordinators. The answers were categorized by frequency and mean of the answers and passed by a statistical test. The results indicated that most of the coordinators had a degree in Biological and Health Sciences, at Masters and PhD levels. The committees had been operating for more than nine years in higher education institutions, with insufficient institutional support. Members were empowered by readings of the Committee’s regulations and guidelines. The distribution of protocols was done by subject affinity and the group decision was given by consensus or vote. It is concluded that the committees are consolidated, comply with ethical regulations, but they need to dialogue more with researchers and with the National Commission of Ethics in Research.

title: Leaf Area Estimate of Erythroxylum simonis Plowman by Linear Dimensions

description: ABSTRACT This research aimed to determine an equation to estimate the leaf area of Erythroxylum simonis using the length and width of leaf blades. Two hundred leaf blades of this species were collected in Mata do Pau-Ferro, a State Park located in Areia, PB, Brazil. Regression analyses were used to determine the estimation equations. The linear, linear without intercept, quadratic, cubic, power and exponential statistical models were used. The criteria used for model selection were based on an examination of the coefficient of determination, the Akaike information criterion and standard error of the estimate. All the equations presented can be used to estimate the leaf area of E. simonis. From a practical point of view, the linear regression equation without intercept involving the product between length and width is recommended, using the equation Y=0.6426*LW, which corresponds to 64.26% of the product between length and width, with a coefficient of determination of 0.9936.

title: Ethical conflicts and limitations of medical care for women victims of gender violence

description: Abstract Domestic violence is the most common type of violence against women, resulting in sequelae in the physical, emotional, family, and economic domains, constituting a public health problem. However, the issue is treated negligently by health professionals, which contributes to its invisibility. Based on a review of the literature, the objective of this study was to identify the main difficulties, including ethical conflicts, found by physicians in the approach to patients who are victims of this type of violence. The basic obstacles are grouped in 3 main axes: issues related to the health professional, to the structure of the health system and to the victims of violence. It is concluded that the greatest obstacle comes from the health professionals themselves, and involves factors ranging from inadequate training to the occurrence of moral and ethical conflicts that culminate in blaming and accountability of the victims for the situation of violence in which they were found.

title: Quantification of Tannins from Curupay Bark

description: ABSTRACT This study aimed to assess the influence of time and sodium sulfite concentration on tannin yield in Curupay bark and propose better extraction conditions. The extractions were performed using 100 g of dried bark and 1500 mL of water at 70 °C, with extraction times of 2, 3, and 4 h and amount of extractor salt at the concentrations of 0, 1, 2, 3, and 4%. The following parameters were evaluated: content of total solids, total yield of solids, Stiasny index, and gravimetric yield of condensed tannins and non-tannins. Results show that the higher the concentration of sodium sulfite, the higher the content and yield of solids, as well as the higher the extraction of non-tannin compounds. Three-hour extraction time at 3.0% sodium sulfite concentration was the best condition to extract tannins from Curupay bark, under which a condensed tannin yield of 20.46% was obtained.

title: The hospital routine of children with prolonged hospitalizations: between body-care and possible mediations

description: This ethnographic study reflected upon the experiences of prolonged hospitalization among children with chronic and complex conditions (CCC). Data was collected from the patients’ medical records, participant observation, and interviews conducted with the parents of children hospitalized in two pediatric units. The findings reveal that the patients’ daily lives were engendered by an intimate relationship between the body and environment and the importance of the mediation of parents and health professionals in this setting. A number of considerations are suggested, including the fact that the health needs of children with CCC extend beyond medication and techniques. It is vital to understand that the daily life of these children is played out temporarily in the hospital and therefore theses settings require the active presence of mothers and the provision of spaces and activities to optimize the daily lives of these children.

title: AGRARIAN POLICY AND TERRITORIAL ORDINATION IN MARAJÓ, PARÁ

description: ABSTRACT Current Brazilian legislation has fundamental elements for the recognition of the territories of traditional populations, in particular in the Amazon, such as the Second National Plan of Agrarian Reform (PNRA). The objective of this study is to analyze the agrarian reform policy stemming from II PNRA and its developments in Marajó, State of Pará. In addition to document analysis and a review of the relevant bibliography, the methodology used was a comparative study, which helps analyze processes of social change and public policy. It was found that despite the efforts of social movements and the consequent inclusion of a number of families in the federal government program, in itself a significant conquest, exogenous interests have prevailed to the detriment of the real recognition of those Marajoara families waiting for a better effectuation of an agrarian reform policy in the region. The study also considered that the limitations in the implementation of this Plan in Marajó has enabled: (i) the continuity of the logging business, a low-income economic activity that causes a large environmental liability, (ii) a platform for political-electoral interests and (iii) the arrival of the agricultural frontier and the structuring of agribusiness.

title: Viability of Brazilwood seeds (Caesalpinia echinata Lam.) stored at room temperature in controlled atmospheres

description: Seed storage at room temperature is an important and low-cost tool for ex situ conservation. However, the high rates of seed deterioration could reduce the potential for storage in this condition. Therefore, the knowledge of the suitable water content for this type of storage plays a critical role. This study aimed to assess the time required to stabilize the relative humidity (RH) in sealed flasks with saturated salt solutions, with or without the introduction of seeds of Caesalpinia echinata, as well as to assess the viability of these seeds stored in environments with different hygroscopic equilibrium. The results showed that 2 and about 12 days are needed to stabilize the RH, respectively, without or with the seeds. The amount of saturated salt solutions in this airtight environment influences both the speed to equilibrate the RH and the final values of the RH. Seeds of Caesalpinia echinata tolerate drying up to 5% water content (wet basis); however, the viability of these seeds at room temperature is maintained for short periods even at low water content.
