title: Invasive Coronary Physiological Assessment in Symptomatic Middle-Aged Endurance Athletes

description: Abstract Despite the health benefits of routine exercise, coronary artery disease (CAD) is common among older competitive athletes and is an important cause of sudden cardiac death. Athletes with suspected or confirmed CAD routinely undergo conventional coronary angiography involving the performance of invasive coronary physiological assessment using the fractional flow reserve (FFR) or the instantaneous-wave free ratio (iFR). Data defining the role of invasive coronary physiological assessment, while robust in general clinical populations, are untested among older competitive athletes with CAD. The paper discusses the challenges and uncertainties surrounding the use of the FFR and iFR in this unique population with an emphasis on the need for future work to better define this approach.

title: Waiting for Cardiac Procedure in Congenital Heart Disease: Portrait of an a Hospital in the Amazonian Region

description: Abstract Background: Congenital heart disease is an important cause of morbidity and mortality in childhood, and in 50% of cases, surgery is required in the first year of life. A high deficit of surgical procedures is estimated in Northern Brazil. Objective: To analyze the waiting time for elective surgical treatment and/ or intervention in children with congenital heart disease in a Cardiology referral center, and to make considerations about heart diseases and forms of treatment in that institution. Methods: A cross-sectional study of all patients aged less than 14 years, with a diagnosis of congenital heart disease that were waiting for elective surgical or percutaneous cardiac treatment. Results: Among the 407 children with congenital heart defects, the most prevalent age group was &gt; 2 to 6 years (34.0%). The average waiting time was 23.1 ± 18.3 months, with a median of 19. The most frequent heart disease was ventricular septal defect (28.98%), patent ductus arteriosus (18.42%) and atrial septal defect (11.05%). Most children (63.4%) were not from the metropolitan area. The percutaneous interventions represented only 27.84% of the catheterization procedures and 14,85% of all heart treatments. Approximately 60% of the pediatric surgeries occurred in children who were not previously registered due to urgency cases. Conclusion: Most of the children waiting for a cardiac procedure were not from the metropolitan area and had malformations potentially treatable by catheterization. It is necessary to increase the capacity of the single referral center in the state of Pará, as well as decentralize the high-complexity cardiological care in the metropolitan region.

title: A robust fully automatic lumen segmentation method for in vivo intracoronary optical coherence tomography

description: Abstract Introduction: Intravascular optical coherence tomography (IVOCT) is an in-vivo imaging modality based on the introduction of a catheter in a blood vessel for viewing its inner wall using electromagnetic radiation. One of the most developed automatic applications for this modality is the lumen area segmentation, however on the evaluation of these methods, the slices inside bifurcation regions, or with the presence of complex atherosclerotic plaques and dissections are usually discarded. This paper describes a fully-automatic method for computing the lumen area in IVOCT images where the set of slices includes complex atherosclerotic plaques and dissections. Methods The proposed lumen segmentation method is divided into two steps: preprocessing, including the removal of artifacts and the second step comprises a lumen detection using morphological operations. In addition, it is proposed an approach to delimit the lumen area for slices inside bifurcation region, considering only the main branch. Results Evaluation of the automatic lumen segmentation used manual segmentations as a reference, it was performed on 1328 human IVOCT images, presenting a mean difference in lumen area and Dice metrics of 0.19 mm2 and 97% for slices outside the bifurcation, 1.2 mm2 and 88% in the regions with bifurcation without automatic contour correction and 0.52 mm2 and 90% inside bifurcation region with automatic contour correction. Conclusion This present study shows a robust lumen segmentation method for vessel cross-sections with dissections and complex plaque and bifurcation avoiding the exclusion of such regions from the dataset analysis.

title: YIELD AND QUALITY OF STRAWBERRY FRUITS FERTILIZED WITH BOVINE BIOFERTILIZER

description: ABSTRACT The objective of this study was to evaluate the effect of different doses of bovine biofertilizer on yield and post harvest of the strawberry crop in different growing environments. The experiment was carried out in two cycles of production, in Fortaleza, Ceará. The experimental design was in randomized blocks, arranged in subdivided plots, where the plots were of three cultivated environments (A1 = protected environment with screens, cold-water spraying, and white floor; A2 = environment with full sun, cold-water spraying, and white floor; A3 = environment with full sun, no cold-water spraying, and grey floor). The subplots consisted of five doses of biofertilizer (D1 = 0,0, D2 = 500, D3 = 750, D4 = 1000 and D5 = 1250 mL plant-1 week -1), with five replications. In the two-year period, the dose was higher in the protected environment of the weed type, with nebulization and on the white floor, at the dose of 500 mL week-1 plant-1 in the first cycle and 325 mL week-1 plant-1 in the second cycle. The dose of bovine biofertilizer of 1250 mL week-1 plant-1 promotes a longer duration and duration of the first cycle. During the second cycle, as the bovine biofertilizer doses of 585 and 620 provide higher and lower output than the protected environment. The environment without nebulization and on the floor without painting, the best soluble practices (Brix) in relation to the protected environment of the type screened and a full sun with nebulization.

title: Contribution of public squares to the reduction of urban flooding risk

description: Abstract Urbanization is directly linked to the process of impermeabilization of the soil in urban areas that contributes to the emergence of flood risks. The purpose of this study was to determine the hydrodynamic properties of the public squares in a flood-prone Brazilian city and determine to what extent they could contribute to the reduction of flooding. The Beerkan method was used to determine the hydrodynamic properties of the soil in nine squares located at critical flooding points in the city of Recife. This method uses simple ring infiltration and the collection of soil samples to obtain the soil granulometric distribution, thereby generating the soil water retention curve θ(h) and the hydraulic conductivity K(θ). The squares studied have similar hydrodynamic characteristics because of their similar soil texture classes, such as Loamy Sand and Sandy Loam. This made it possible for eight of the nine squares studied to be able to contribute positively to the reduction of flood risks by adapting them into micro infiltration basins that can receive the surface flows that overload the drainage network.

title: Occupy with cinema – writing the history of urban struggles in Ressurgentes – um filme de ação direta

description: Abstract The article analyses the retaking of archives of about 10 years of urban struggles conducted by autonomous movements of Brasília and its articulation through the editing in the documentary Ressurgentes – um filme de ação direta. We are interested in pointing out how the association of these heterogeneous archives with the testimonies of militants beget a peculiar writing of the history of urban problems experienced in Brasilia in the last decade and their possible relations to common events to other cities, such as June’s 2013 manifestations.

title: PREPARING FOR THE COMPLEXITIES OF TEACHING: MODELING CONCEPTUAL THINKING IN POST-OBSERVATION CONFERENCES

description: In order for teacher educators to prepare teachers for complexities of language teaching, their nature needs to be understood. Vygotskian sociocultural theory offers a useful framework for construing such complexities. Vygotsky distinguished between everyday and scientific concepts, and saw the interaction of the two as conceptual thinking, the basis for higher order cognitive skills. Johnson (2009) frames learning to teach as the development of conceptual thinking and considers the nature of the dialogue in teacher education activities as crucial to this development. Drawing on longitudinal data from a semester-long case study of the dialogic interactions between a teacher and teacher educator, this study illustrates how the teacher educator modeled conceptual thinking in her language. We propose a taxonomy of conceptualizations about language teaching that may help teacher educators be more purposeful in designing activities for and interacting with novice teachers.

title: Activated carbon loaded with manganese and iron for glyphosate adsorption: Kinetics, isotherms and thermodynamic studies

description: Abstract Granular activated carbon was loaded with 0.5% manganese and 1.0% iron (m/m) for glyphosate removal from aqueous solutions. The adsorbent material was characterized by scanning electron microscopy, dispersive energy spectrometry, nitrogen adsorption techniques and zeta potential analyses. Batch studies were performed to investigate the adsorption equilibrium, kinetics mechanisms and to obtain thermodynamic information. Glyphosate adsorption increased with the contact time and achieved equilibrium within 24 h, with a maximum adsorption capacity of 9.19 mg g-1 at 45°C. Batch kinetic experimental data obeyed the pseudo-second-order model with R2&gt;0.99. Adsorption isotherm experiments were carried out at 5, 15, 25, 35 and 45°C. The adsorption isotherms presented a better fitting using the Freundlich model (R2&gt;0.98), indicating a multilayer adsorption of glyphosate. Thermodynamics studies showed that the adsorption of glyphosate onto granular activated carbon loaded with manganese and iron was spontaneous and feasible with negative values of ΔG°, endothermic with ΔH° of 20.924 kJ mol-1 and ΔS° of -73.250 J mol-1 K-1, suggesting a decrease in randomness at the solid-liquid interface between glyphosate and the adsorbent. The experimental results demonstrated that activated carbon loaded with manganese and iron may be an alternative for glyphosate removal in water, wastewater treatment and purification processes.
