title: Physicochemical Properties and Bioactive Potential of a New Epoxy Resin-based Root Canal Sealer

description: Abstract The aim of this study was to evaluate physicochemical properties and bioactive potential of Sealer Plus, in comparison with MTA Fillapex, Sealapex and AH Plus. Setting time, flow, and radiopacity were evaluated based on ISO 6876 Standard. Flow was also assessed in area (mm²). The solubility and volumetric change of the sealers were evaluated after 7 and 30 days of immersion in distilled water. Solubility was evaluated by the difference in mass of materials before and after immersion. Volumetric change was evaluated by using microcomputed tomography (micro-CT). The bioactive potential was observed by Scanning Electron Microscopy (SEM) after immersion in PBS. Data were compared using ANOVA and Tukey tests (α=0.05). Sealer Plus presented the shortest setting time (196 min.) and Sealapex the longest (912 min.) (p&lt;0.05). AH Plus showed the highest radiopacity (9.5 mm Al) and MTA Fillapex the lowest (2.7 mm Al) (p&lt;0.05). All the sealers presented flow in accordance with ISO 6876/2012 (&gt;17 mm). Sealer Plus showed low solubility and volumetric change (&lt;1%), and MTA Fillapex showed the highest solubility (&gt;25%), and volumetric change (&gt;4%) after all time intervals (p&lt;0.05). MTA Fillapex was the only sealer that showed bioactive potential. In conclusion, Sealer Plus presented proper physicochemical properties. However, this sealer did not present a bioactive potential.

title: Fractions in the Continuing Formation of Teachers of the Early Years: fragments of a complexity

description: Abstract This work presents aspects of a qualitative research, of phenomenological approach, developed in the scope of the continuous formation of Mathematics teachers. Here, we present a training bias that recognizes teachers' estrangement as a triggering factor for the formative movement of sixteen teachers, in the theme of fractions as a school content. The analysis is based on the formative possibility of a four-hour meeting, which had as a starting point the perplexities of the teachers when they were asked what is familiar to each one of them when talking about the understanding of fraction. In a phenomenological posture, estrangement stands out as a philosophical attitude that moved the formation, allowing the arising of questions about school content and its teaching. In this perspective, the teachers' "realization" about the predominance of the technique and formal nomenclatures, with which they were launched to the attribution of fractional meanings, having as proposal the location in a number line. The study revealed the importance of a formation style in which the teacher is called by the anxieties that appear in the dialogue with their peers. Style, which considers the didactic technique, using a reorientation of the way of thinking, feeling and conceiving the world, given the uncertainty of learning each day how to be a teacher.

title: Edible iron yam and maize starch convenient food flavoring packaging films with lemon essential oil as plasticization

description: Abstract Lemon essential oil was used as plasticizers to prepare iron yam/maize starch edible films. Changes of physical, microcosmic and antimicrobial properties of films were studied. Results showed that the addition of lemon essential oil led to the decrease of moisture content, transparency, whiteness index, water vapor permeability, solubility and tensile strength and the increase of b*, elongation and haze values. With the increase of lemon essential oil content, the antibacterial activity increased, and the surface and internal microstructure of the film became more and more heterogeneous. Compared with the control group, the tensile strength, water content and WVP of IYM/2LO films decreased by 21.9%, 23.5%, and 23.6%, respectively. When surfactant was added, the antimicrobial activity, solubility, haze, surface coarseness and porosity increased significantly, and the tensile strength decreased from 11.8MPa (IYM/1LO) to 7.60MPa (IYM/1LO/0.1S) obviously. The iron yam/maize starch edible films with good physical and antibacterial properties can be considered as convenient food flavoring packaging materials.

title: Analog Models of Flanking Structures and a Natural Example in the Quadrilátero Ferrífero, Minas Gerais

description: ABSTRACT The aim of this study is to present analog models of flanking structures and to analyze the Fábrica Nova synform, Quadrilátero Ferrífero, Minas Gerais, from a geometric point of view. We set up seven models using a linear viscous silicone and produced flanking structures with a shear velocity of 2 cm h-1. At different initial orientations with respect to the shear zone boundary, a rigid cross-cutting element with lubricated boundaries was deformed via sinistral bulk flow at a shear strain of γ = 1.28. The most interesting features of our experiments are the geometries of the different marker lines, which are heterogeneous and resulted from thickening and thinning of the silicone at the cross-cutting element terminations. To compare our analog models and the Fábrica Nova synform, we analyzed the outermost marker line of the analog models and the top surface of the Cauê Formation in the Paleoproterozoic metasediments. The best comparisons between the experiments and the natural example were obtained by our CIS90 model in terms of the flexure shape near the cross-cutting element and the cross-cutting element orientation. Thus, we suggest that the cross-cutting elements in both situations act as obstacles and consequently produce local perturbations in laminar flow.

title: Modeling and mapping basal area of Pinus taeda L. plantation using airborne LiDAR data

description: ABSTRACT Basal area (BA) is a good predictor of timber stand volume and forest growth. This study developed predictive models using field and airborne LiDAR (Light Detection and Ranging) data for estimation of basal area in Pinus taeda plantation in south Brazil. In the field, BA was collected from conventional forest inventory plots. Multiple linear regression models for predicting BA from LiDAR-derived metrics were developed and evaluated for predictive power and parsimony. The best model to predict BA from a family of six models was selected based on corrected Akaike Information Criterion (AICc) and assessed by the adjusted coefficient of determination (adj. R²) and root mean square error (RMSE). The best model revealed an adj. R²=0.93 and RMSE=7.74%. Leave one out cross-validation of the best regression model was also computed, and revealed an adj. R² and RMSE of 0.92 and 8.31%, respectively. This study showed that LiDAR-derived metrics can be used to predict BA in Pinus taeda plantations in south Brazil with high precision. We conclude that there is good potential to monitor growth in this type of plantations using airborne LiDAR. We hope that the promising results for BA modeling presented herein will stimulate to operate this technology in Brazil.

title: Acute effect of passive cycloergometry on the cardiovascular system and respiratory mechanics of critically ill patients: a randomized controlled trial

description: Abstract Introduction: The rehabilitation of critical patients usually occurs in the bed and is classified as low cardiovascular intensity. Therefore, it is essential to understand the physiological effects of these resources that we apply in clinical practice. Objective: Evaluate the acute effect of passive cycloergometry of lower limbs on respiratory mechanics and cardiovascular parameters in critically ill patients. Method: This was a labeled, randomized, controlled trial conducted in two intensive care units in the city of Recife, between August 2016 and May 2017. Patients were divided into two groups: (i) passive cycloergometry group (n = 16), where the patient performed a lower limb cycloergometry session for 20 minutes, and (ii) control group (n = 14), where the patient did not perform any therapeutic intervention, except during the application of the protocol. Cardiovascular parameters and respiratory mechanics were evaluated before, during and after their applicability. Results: No demographic differences were found between the two groups, showing the homogeneity between them. Regarding cardiovascular parameters, there were no differences between groups before, during and after the protocol. Regarding respiratory mechanics, there was a slight elevation of the resistance of the respiratory system in the cycloergometry group and a reduction of the same in the control group. Conclusion: The results suggest that passive cycloergometry applied to the critical patient did not promote significant cardiovascular changes and respiratory mechanics, being considered a safe and effective technique in clinical practice that can be applied without causing harm to patients under mechanical ventilation.

title: Homeless people and public policies: representations in Folha de São Paulo

description: ABSTRACT In this paper, we discuss the representation of homelessness in the news about public policies published in the Folha de S. Paulo (FSP) portal between 2011 and 2013. Our objective is to reflect on how these representations influence the perception of the social problem as the focus of public action and its agenda in the public agenda. For this, we have mapped 105 texts on public policies of the 460 collected on homelessness. To analyse this corpus, we have used the software NVivo. Based on critical discourse studies, we mainly investigate which voices are summoned to speak about / in the name of this population and how the group is evaluated in this thematic context. The analysis allows to conclude that the representation of homelessness is prejudiced and to suggest that this vision can contribute to the definition of hygienist public policies and their social acceptance.

title: Intensive Neuromotor Therapy improves motor skills of children with Cornelia de Lange Syndrome: case report

description: Abstract Introduction: The Cornelia de Lange Syndrome (CdLS) is a rare genetic syndrome. Children with CdLS usually require physical therapy, however the efficacy of physical therapy intervention in this population is lacking in the research literature. Objective: The aim of this study was to report the effect of Intensive Neuromotor Therapy (INMT) on gross motor function and participation of a child with CdLS using the International Classification of Functioning, Disabilities and Health (ICF) model. Method: A Brazilian child with CdLS was followed for over seven months while undergoing three modules of INMT. Results: The child demonstrated an evolution of gross motor function with gains of 11.28% in the first module, 9.22% in the second module, and 10.29% in the third module of INMT. Conclusion: INMT resulted in improvements in gross motor function and participation during daily activities in a child with CDLS. Further studies of larger cohorts are needed to investigate the efficacy of INMT in children with CdLS.

title: Factors associated with body balance of long living elders

description: Abstract Introduction: It is estimated that the elderly life is related to disturbances of balance, freedom in activities and social isolation. Objective: Measures to balance the body in the long-lived elderly. Method: An analytical cross-sectional study was performed on patients aged 80 and over, male and female. Patients underwent clinical assessment and physical-medical tests: Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Timed Up and Go (TUG) test and sit to stand test. Descriptive analyses singles with the testing of Mann-Whitney and Kruskal-Wallis, consecutively by the Dunn test and Spearman’s alpha coefficient &lt; 0.05. Results: There was a significant association between BBS and the following variables: fear of falling (p = 0.029), use of walking aid (p = 0.001), physical activity (p &lt; 0.001), stroke episode (p = 0.007), musculoskeletal diseases (p = 0.027) and pain (p = 0.045). Significant correlations are variables between the BBS scores and the quantitative variables such as age (ρ = -0.316, p &lt; 0.001), number of diseases (ρ = -0.26663, p = 0.0062), number of falls (ρ = -0,214, p = 0,0279), DGI (ρ = 0,713, p &lt; 0,0001), sit to stand test (ρ = -0.418, p &lt; 0.001), and TUG (ρ = -0.658, p &lt; 0.05). The results were statistically significant (p &lt; 0.01) 0.001). Conclusion: Body balance in the elderly gets more compromised with age, higher number of diseases, more falls, worse gait performance, decreased strength in the lower limb and mobility, stroke and musculoskeletal disorders, presence of complaints, use of marching support, fear of falling and not doing physical activity.

title: Erosion of the nocturnal boundary layer in the central Amazon during the dry season

description: ABSTRACT In this study, the erosion of the nocturnal boundary layer (NBL) was analyzed in the central Amazon during the dry season of 2014, using data from the GoAmazon 2014/5 Project and high-resolution model outputs (PArallelized Les Model - PALM). The dataset consisted of in situ (radiosonde) and remote sensing instruments measurements (Ceilometer, Lidar, Wind Profiler, microwave radiometer, and SODAR). The results showed that the NBL erosion occurred, on average, two hours after sunrise (06:00 local time), and the sensible heat flux provided more than 50% of the sensible heating necessary for the erosion process to occur. After the erosion, the convective phase developed quickly (175.2 m h-1). The measurements of the remote sensors showed that the Ceilometer, in general, presented satisfactory results in relation to the radiosondes for measuring the height of the planetary boundary layer. The PALM simulations represented well the NBL erosion, with a small underestimation (≈ 20 m) at the beginning of this phase. In the final phase of NBL erosion and in the initial stage of the development of the convective boundary layer (CBL), the model presented satisfactory results, with heights of CBL ranging from 800 m to 1,650 m, respectively.

title: Epidemiological and clinical aspects of snakebites in the upper Juruá River region, western Brazilian Amazonia

description: ABSTRACT This study addresses the clinical and epidemiological aspects of envenoming cases resulting from snakebites treated at a hospital in Cruzeiro do Sul, in the upper Juruá River region, western Brazilian Amazonia. The specific identity of snakes that caused the envenomings was inferred (a) from the diagnosis of patient symptoms and signs upon hospital admission, (b) by enzyme immunoassay for detection of Bothrops atrox and Lachesis muta venom from serum samples taken from patients before antivenom therapy, or (c) by direct identification of the snake, when it was brought along to the hospital or photographed. There were 133 snakebites (76.2 cases per 100,000 inhabitants) registered during one year (July 2017 to June 2018). Most snakebites (88.7%) were caused by Bothrops spp., and the rest by non-venomous snakes or dry bites. Snakebites tended to occur more often during the rainy season, coinciding with the period of greater reproductive activity of the snakes and greater availability of their prey. In addition, the increase in the water level of rivers and lakes during the rainy season tends to concentrate snakes in dry places and, thus, to increase encounters with humans. Information campaigns on prevention and first aid, specially among the most vulnerable groups (indigenous people, farmers, and children and teenagers in rural areas), and the importance of using protective equipment (boots, leggings, leather gloves) in certain high risk activities (e.g. agriculture and extractivism in forests) are fundamental for the reduction of snakebite morbidity.
