title: Performance of juice and wine grape cultivars in different training systems

description: Abstract The increase of rural tourism activities has led growers to use different grape cultivars for the production of wine and/or juice. Thus, the aim of this study was to evaluate the phytotechnical characteristics of grapevines and physicochemical characteristics of grape must obtained for Bordô, Isabel Precoce, BRS Violeta, Isabel and Concord cultivars in different training systems: vertical shoot position; Y-shaped trellis and V-shaped trellis with double spur cordon. The experimental design was randomized blocks for comparison of cultivars within each training system and analysis of the main components for productivity variables was carried out. BRS Violeta cultivar showed higher bunch weight values regardless of training system. Bordô cultivar showed lower yield values and soluble solids content in comparison to other cultivars. Isabel and Isabel Precoce cultivars in the evaluated training systems showed higher soluble solids content. Principal component analysis allowed verifying that in Y-shaped trellis and V-shaped trellis with double spur cordon training systems, cultivars were related to higher yield.

title: Spondias mombin and Theobroma grandiflorum in agroforestry system: productivity implications

description: Abstract In agroforestry systems, little is known about the influence of the dominant species on that located in the lower layer of the canopy. The aim of this study was to evaluate if S. mombin plants, when in consortium with T. grandiflorum, caused some type of depression in the performance of T. grandiflorum and also to identify the most favorable S. mombin clones for this interaction. The experiment started on February 2005. During 11 years, four levels of influence of S. mombin on T. grandiflorum caused by the proximity between species were evaluated. As response variables, the vegetative development of S. mombin and T. grandiflorum was measured; the production of eight vintages T. grandiflorum trees was computed, and the mortality rate of plants was recorded. The results showed that the competition exerted by S. mombin moderately affected the initial development of plants, as well as the production of fruits in the last harvests, and the survival rate. The most favorable S. mombin clones to be used in agroforestry systems with T. grandiflorum trees were identified. According to results presented here, it was possible to conclude that S. mombin can be indicated as a species to compose AFS with T. grandiflorum.

title: Relationship between soil organic matter fractions and cover plants in Olive post planting

description: Abstract Erosion is the main cause of soil degradation, compromising soil productivity and sustainability. As soil organic matter (SOM) is a key indicator of quality, this study aimed to evaluate the effect of different olive tree managements on SOM and its soil fractions in soil (Inceptisol) and erosion sediments. Five treatments were installed: bare soil, olive cultivation in bare soil, olive tree intercropped with jack bean, olive tree intercropped with pearl millet, and olive tree cultivated with spontaneous vegetation; a contiguous area of native vegetation was used as reference. Carbon in soil and sediment were determined by wet oxidation with external heating, while the fractionation of SOM was performed based on granulometry. The Carbon Management Index (CMI) was determined by the proportions of SOM fractions. The results indicated that SOM associated with minerals is the most present in soil and sediment erosion, regardless of the adopted management. Results on CMI showed that the systems olive tree intercropped with pearl millet or with spontaneous vegetation are the most favorable to increase the carbon stock in the soil.

title: The role of the exogenous supply of adenosine triphosphate in the expression of Bax and Bcl2L1 genes in intestinal ischemia and reperfusion in rats

description: Abstract Purpose: To investigate the role of the exogenous supply of adenosine triphosphate (ATP) in the expression of Bax and Bcl2L1 genes in intestinal ischemia and reperfusion (IR) in rats. Methods: The study was designed as a randomized controlled trial with a blinded assessment of the outcome. Eighteen adult male Wistar-EPM1 rats were housed under controlled temperature and light conditions (22-23°C, 12 h light/dark cycle). The animals were randomly divided into 3 groups: 1. Sham group (SG): no clamping of the superior mesenteric artery; 2. Ischemia and reperfusion group (IRG): 3. Ischemia and reperfusion plus ATP (IRG + ATP). ATP was injected in the femoral vein before and after ischemia. Afterwards, intestinal segments were appropriately removed and processed for Endothelial Cell Biology Rat RT2 Profiler PCR Array. Results: ATP promoted the upregulation of Bcl2L1 gene expression, whereas it did not have significant effects on Bax gene expression. In addition, the relation of Bax/Bcl2L1 gene expression in the IRG group was 1.39, whereas it was 0.43 in the IRG + ATP group. Bcl2L1 plays a crucial role in protecting against intestinal apoptosis after ischemia and reperfusion. Increased Bcl2L1 expression can inhibit apoptosis while decreased Bcl2L1 expression can trigger apoptosis. Conclusion: Adenosine triphosphate was associated with antiapoptotic effects on the rat intestine ischemia and reperfusion by upregulating of Bcl2L1 gene expression.

title: Planning a didactic sequence on electric power from the perspective of STS

description: Abstract: In this work, a didactic sequence was planned by linking the epistemological and pedagogical dimensions to Science, Technology and Society (STS) assumptions.. Electric power was defined as a theme due to the importance of the Furnas Hydroelectric Plant as energy matrix in the south of Minas Gerais (Brazil) which is part of the reality of students from this region. The difficulties of the teaching and learning process were established as well as the resources and strategies of teaching were defined in order to enhance the understanding of contents. It was considered that dimensions may widen the perception by the teacher about the theme and promote interactions which benefit the taking of decisions that enable reflection about the theme from the perspective of STS. Thus, the didactic sequence described might provide a better perception of teaching to the teacher who can explore scientific concepts from the theme related to the daily life of students.

title: The effect of matinal active walking on cognitive, fine motor coordination task performances and perceived difficulty in 12-13 young school boys

description: Abstract Aim: The current study examined the relationship between cognitive performances (executive function, selective attention and reaction time), fine motor coordination skills and perceived difficulty after active transport to school. Method: Fifteen right-handed children’s underwent session, 15-min walking session at 30% (WS1) and 15-min walking session (WS2) at 50% of maximal aerobic speed. Subjects performed tests to evaluate executive function, reaction time and selective attention. After each trial, a questionnaire of perceived difficulty (PD) was completed. Results: Average time in TMT part A (F(2,22) = 4.44; p = 0.024; η2= 0.288) and TMT part B (F(2,22) = 4.54; p = 0.022; η2= 0.292), and committed errors (F(2,22) = 7.78; p = 0.003; η2= 0.414) was improved after walking sessions in comparison by CS. The mean scores were significantly higher after walking sessions for both long and short-distance throws (p &lt; 0.05). Moreover, a significant negative correlation was found between committed errors (TMT part B) and both dart throwing consistency and accuracy (r = - 0.6; r = - 0.64; p &lt; 0.05) (respectively). Post-hoc analysis showed that PD was better after walking sessions with low intensity for both short and long throwing distance. However, it seems that walking session with sustained intensity allows speed and accuracy improvement of cognitive processing. Conclusion: Thus, active walking to school with low intensity was sufficient to produce positives changes in psychomotor performance and decrease in perceived difficulty scores. By including individual differences in gross motor coordination as well as physical activity level, the exact nature of the link between psychomotor skills and cognitive performance could be more addressed.

title: Phenotypic plasticity in a soybean cultivar with indeterminate growth type

description: Abstract: The objective of this work was to evaluate how branch and stem variables contribute to grain yield in individual soybean (Glycine max) plants, cultivated at different planting densities, in a modern cultivar with indeterminate growth type. A field experiment was carried out during the 2013/2014 and 2014/2015 crop seasons, in a randomized complete block design with 12 replicates, using the cultivar NK7059 RR at four planting densities: 135, 235, 315, and 440 thousand plants per hectare. Grain yield per plant was evaluated and represented phenotypic plasticity, while the number of branches per plant, percentage of grain production in branches, and separate yield components from branches and stems were considered as the independent variables. The number of pods in branches per plant was found to be the most important variable for soybean plasticity. In addition, the number of pods per plant on stems, number of branches per plant, and the percentage of grain production in branches were also associated with plasticity. Contrastingly, the number of grains per pod and the mass of a thousand grains in the branches and stems contributed little to plasticity in 'NK7059 RR' soybean.

title: Mortality for Critical Congenital Heart Diseases and Associated Risk Factors in Newborns. A Cohort Study

description: Abstract Background: Congenital heart diseases are the most common type of congenital defects, and account for more deaths in the first year of life than any other condition, when infectious etiologies are ruled out. Objectives: To evaluate survival, and to identify risk factors in deaths in newborns with critical and/or complex congenital heart disease in the neonatal period. Methods: A cohort study, nested to a randomized case-control, was performed, considering the Confidence Interval of 95% (95% CI) and significance level of 5%, paired by gender of the newborn and maternal age. Case-finding, interviews, medical record analysis, clinical evaluation of pulse oximetry (heart test) and Doppler echocardiogram were performed, as well as survival analysis, and identification of death-related risk factors. Results: The risk factors found were newborns younger than 37 weeks (Relative Risk - RR: 2.89; 95% CI [1.49-5.56]; p = 0.0015), weight of less than 2,500 grams (RR: 2.33 [; 95% CI 1.26-4.29]; p = 0.0068), occurrence of twinning (RR: 11.96 [95% CI 1.43-99.85]; p = 0.022) and presence of comorbidity (RR: 2.27 [95% CI 1.58-3.26]; p &lt; 0.0001). The incidence rate of mortality from congenital heart disease was 81 cases per 100,000 live births. The lethality attributed to critical congenital heart diseases was 64.7%, with proportional mortality of 12.0%. The survival rate at 28 days of life decreased by almost 70% in newborns with congenital heart disease. The main cause of death was cardiogenic shock. Conclusion: Preterm infants with low birth weight and comorbidities presented a higher risk of mortality related to congenital heart diseases. This cohort was extinguished very quickly, signaling the need for greater investment in assistance technology in populations with this profile.

title: Magnetic drag and Foucault currents: a low cost experiment with video analysis

description: Abstract In this work, we present a low-cost experiment to study the phenomenon of magnetic drag. It is a difficult subject to be studied experimentally, especially in schools that do not have a laboratory. The experiment makes possible the discussion about the Faraday's Law and the Foucault currents, in a practical way and using only few physical resources. The data acquisition is carried out through a smartphone. The data processing is performed by the association of a video-analysis tool, the free software Tracker, and a data analysis tool, the free software LibreOfficeCalc. In this way, the experimental activity proposed in this text can be adpated to the most diverse school realities.
