title: FAO’S RURAL DEVELOPMENT AND EDUCATION PROPOSALS IN THE 1950’S AND TODAY: FORGING CONSENSUS AS SOCIAL DISGUISE

description: ABSTRACT: The Food and Agriculture Organization - FAO, a UN Agency - acts with expressiveness in hunger relief and rural development programs in Brazil, as well as in other countries in Latin America, the Caribbean and Africa. In this article we analyze the relationship between FAO’s rural development proposal and educational principles advocated by the agency during the 1950’s and also since 2005. The study was conducted through secondary and primary sources. Summarizing the conclusions, today, as in the 1950s, the organization supports campaigns that gather antagonistic social sectors around projects that promote insertion of countryside population subordinated to market’s logic, a strategy consistent with FAO’s methodology for the establishment of social consensus for rural and educational development.

title: READING CIÊNCIA HOJE DAS CRIANÇAS: THE MAGAZINE’S USAGE MODES AND OWNERSHIPIN CLASSROOM

description: ABSTRACT: This work deals with usage modes and magazine ownership of Ciência Hoje das Crianças in an elementary school’s early grade class. Theoretical and methodological perspective analysis are inspired by Bakhtin and Vygotsky’s conceptions of verbal interaction and “educational memory” in classroom events. The analysis indicates that using Ciência Hoje das Crianças in classroom helps circulate science communication language. It emphasizes the magazine’s importance in Science classes, given the level of involvement of children and teacher, learning scientific content and the quality of participation of all during pedagogical experience with the publication. However, this attitude is not built spontaneously and is related, among other things, to the access of the magazine in class and how the activities were conducted by the teacher.

title: INDIVIDUAL LEARNING, ORGANIZATIONAL SUPPORT AND PERCEIVED TEACHING PERFORMANCE: A STUDY WITH UNIVERSITY TEACHERS

description: ABSTRACT: This article analyzes university teachers’ perception about competences’ learning processes and their perceived performance, as well as the moderating role exercised by organizational support in the relationship between individual learning and perceived teaching performance. To explore the relationship among competency learning, support and job performance, a survey was carried out with 275 teachers from a federal university in the northeast of Brazil, that replied to the perception inventory of competency learning, transference support and teacher performance (ASOD). By analyzing the replies, it was confirmed that teacher learning in teaching, research, extension and management activities is the best predictor of performance perception. No evidence was found that the support moderates the relationship between teacher learning and perceived performance in the four activities.

title: Measurement of nitrogen content in rice by inversion of hyperspectral reflectance data from an unmanned aerial vehicle

description: ABSTRACT: The Nitrogen content of rice leaves has a significant effect on growth quality and crop yield. We proposed and demonstrated a non-invasive method for the quantitative inversion of rice nitrogen content based on hyperspectral remote sensing data collected by an unmanned aerial vehicle (UAV). Rice canopy albedo images were acquired by a hyperspectral imager onboard an M600-UAV platform. The radiation calibration method was then used to process these data and the reflectance of canopy leaves was acquired. Experimental validation was conducted using the rice field of Shenyang Agricultural University, which was classified into 4 fertilizer levels: zero nitrogen, low nitrogen, normal nitrogen, and high nitrogen. Gaussian process regression (GPR) was then used to train the inversion algorithm to identify specific spectral bands with the highest contribution. This led to a reduction in noise and a higher inversion accuracy. Principal component analysis (PCA) was also used for dimensionality reduction, thereby reducing redundant information and significantly increasing efficiency. A comparison with ground truth measurements demonstrated that the proposed technique was successful in establishing a nitrogen inversion model, the accuracy of which was quantified using a linear fit (R2=0.8525) and the root mean square error (RMSE=0.9507). These results support the use of GPR and provide a theoretical basis for the inversion of rice nitrogen by UAV hyperspectral remote sensing.

title: CURRICULUM PERSPECTIVES ABOUT PEDAGOGUE TRAINING FOR NON-SCHOOL EDUCATION

description: ABSTRACT: This paper presents reflections derived from a curriculum study guided by the goal of mapping demonstrative elements of the current framework of pedagogue training for professional performance in contexts of Non-School Education (NSE). The curriculum study covered Pedagogical Projects of Pedagogy Courses from 20 brazilian public universities and analytical procedures were structured by the use of categorial content analysis technique. Underlying framework in the analysis is based on the discussion of the epistemological character of Pedagogy, as well as the critical approach around curricular perspectives that constitute Pedagogy course’s traditions in Brazil. From analytical results, it is recognized the little expressiveness of specific knowledge relating to the NSE in Pedagogy courses’ curricular settings and, as a result, the challenges of structuring formation routes that are associated with the demands of new employability spaces for pedagogues.

title: Reduction of flammability of Pinus elliottii wood modified with TiO2 particles

description: ABSTRACT Wood is composed by polymeric materials, with fire susceptibility. For applications, wood with better ignition resistance and lower fire stenght reduction is desirable. Enhancing of wood thermal properties can be achieved by means of right modification of wood by treatment. Thus, the microwave-assisted solvotermal process was implemented to modify the surface of the Pinus elliotttii wood with TiO2 in order to increase the resistance to flammability and thermal degradation through the retardation of carbonization. An alcoholic precursor solution with titanium isopropoxide was prepared and nanoparticles of TiO2 were crystallized to anatase on wood surface and interior at 140°C, for 60 minutes. Using Scanning Electron Microscopy, it was possible to demonstrate the uniform and homogeneous coating, and by Fourier transform infrared spectroscopy, it was possible to indicate presence of hydrogen bonds between the two materials. The formation of protective particle layer afforded greater stability and thermal resistance due to the ceramic character of TiO2. From the thermogravimetric analysis, 70% of weigh loss at 380°C and 11% of residual content at 700°C was verified, differently from the modified wood that at these temperatures reached 45% and 46%, respectively. Corroborating with these results, it was evident from the flame tests that wood with the presence of particles delayed about 7 times the moment of ignition. Thus, the microwave-assisted solvotermal process has great potential to transform wood and other porous materials into a less flammable material, maintaining its entire structure for a longer time when exposed to adverse conditions

title: Rational Use of Mechanical Circulatory Support as a Bridge to Pediatric and Congenital Heart Transplantation

description: Abstract Introduction: Donor shortage and organ allocation is the main problem in pediatric heart transplant. Mechanical circulatory support is known to increase waiting list survival, but it is not routinely used in pediatric programs in Latin America. Methods: All patients listed for heart transplant and supported by a mechanical circulatory support between January 2012 and March 2016 were included in this retrospective single-center study. The endpoints were mechanical circulatory support time, complications, heart transplant survival and discharge from the hospital. Results: Twenty-nine patients from our waiting list were assessed. Twelve (45%) patients were initially supported by extracorporeal membrane oxygenation (ECMO) and a centrifugal pump was implanted in 17 (55%) patients. Five patients initially supported by ECMO were bridged to another device. One was bridged to a centrifugal pump and four were bridged to Berlin Heart Excor®. Among the 29 supported patients, 18 (62%) managed to have a heart transplant. Thirty-day survival period after heart transplant was 56% (10 patients). Median support duration was 12 days (interquartile range [IQR] 4 - 26 days) per run and the waiting time for heart transplant was 9.5 days (IQR 2.5-25 days). Acute kidney injury was identified as a mortality predictor (OR=22.6 [CI=1.04-494.6]; P=0.04). Conclusion: Mechanical circulatory support was able to bridge most INTERMACS 1 and 2 pediatric patients to transplant with an acceptable complication rate. Acute renal failure increased mortality after mechanical circulatory support in our experience.

title: Drying kinetics of blackberry leaves

description: ABSTRACT Blackberry leaves have some pharmacological properties and one of the most widespread and studied uses is to relieve symptoms of the climacteric and other symptoms during the premenstrual period. Thus, drying becomes important for the conservation and storage of the product until its use or processing. The present study aimed to evaluate the drying kinetics of blackberry leaves, as well as to determine the effective diffusion coefficient and the activation energy during the drying process. Blackberry leaves were dried in an experimental fixed-bed dryer under four controlled temperature conditions (40, 50, 60 and 70 °C) and two drying air speeds (0.4 and 0.8 m s-1). With the experimental data of moisture ratio, eight mathematical models were fitted to represent the process of thin-layer drying of agricultural products. Based on the obtained results, it was found that the Midilli model represented best the phenomenon of drying of blackberry leaves. The increase in temperature and air speed reduced the drying time of blackberry leaves and increased the values of the effective diffusion coefficient. This relation can be described by the Arrhenius equation, which has an activation energy for the liquid diffusion during drying of 65.94 and 66.08 kJ mol-1, for drying air speeds of 0.4 and 0.8 m s-1, respectively.

title: Photosynthetic responses of species of Anibae exposed to contrasting light environments

description: Abstract Photosynthesis of species of Anibae in response to the exposure to contrasting light environments. Ecophysiological traits and the light environment have implications for the establishment of forest plantations. The aim of this study was to investigate the photosynthetic activity of Aniba canelilla and A. rosaeodora in response to changes in the availability of light in the field. Gas exchange, content of chlorophylls (ICC) and photochemical performance (FV/FM) were measured in leaves acclimated in the shade during 300 days, after in the full sun (28 days) and again in the shade by 28 days. The photosynthesis, ICC and FV/FM of A. Canelilla and A. rosaeodora were negatively affected in full sunlight, but the plants recovered when submitted to shade. Photosynthesis, ICC and FV/FM were twice as high in shade plants. Aniba rosaeodora presented photosynthetic performance twice higher than A. canelilla. Differences in photosynthetic responses to light suggest that species could occupy different succession “niches” in enrichment plantation, and plasticity (recovery-mediated) implies acclimatization under variable light environments. The fact that the studied species of Anibae have differences in plasticity for light should be viewed with caution to suggest conventional plantations, but it reinforce the indication for enrichment plantations in forest sites with variations in the availability of light.
