title: Absorption of nutrients by soursop seedlings in response to mycorrhizal inoculation and addition of organic compost1

description: ABSTRACT The use of organic composts and the inoculation of arbuscular mycorrhizal fungi (AMF) are management alternatives in organic production systems. This study aimed to evaluate the effect of AMF inoculation (Acaulospora scrobiculata, Acaulospora colombiana and without inoculation) and organic compost of cacao bark (0 g dm-3, 5 g dm-3, 10 g dm-3, 20 g dm-3 and 30 g dm-3) on the mycorrhizal efficiency and nutrient uptake, in 'Morada' soursop seedlings. The experimental design was completely randomized, in a 3 x 5 factorial arrangement (AMF x organic compost), with four replicates. A higher mycorrhizal efficiency was observed for the A. colombiana isolate, with the addition of 0 g dm-3, 5 g dm-3 and 10 g dm-3 of organic compost to the soil, in relation to the A. scrobiculata isolate, which differed statistically at the doses of 20 g dm-3 and 30 g dm-3 of organic compost. The AMF inoculation promotes increases in the N, P, K, Zn, Cu, Fe and Mn contents, when compared to plants without inoculation. The organic compost exerts an effect on the inoculation, mainly on the absorption of P. The AMF inoculation, together with the organic fertilization, promotes the growth and nutrition of seedlings.

title: The Objective Concept of a Mathematical Task for Future Teachers

description: Abstract Within the line of teacher training, we present in this work aspects of a research with future elementary school teachers, where we focus on understanding how students of the University of Granada interpret the objective as an analysis element of a school mathematical task, framed within the Didactic Analysis as a functional tool in the initial formation. A qualitative methodology has been followed through content analysis. The antecedents show the importance of the school tasks to favor mathematics learning and the results show us the difficulty that the future teachers present to establish and to define the objective of a school mathematical task.

title: Quality of sesame seeds produced under soil salinity levels1

description: ABSTRACT Sesame is considered an alternative crop for small and medium farmers in the Brazilian Northeast region. However, under the conditions of the northeastern semi-arid region, the scarcity of good quality water for irrigation may lead to a reduction in the quality of the final product. This study aimed to evaluate the physiological quality of sesame seeds produced under levels of soil salinity. The experiment was carried out in a completely randomized design, in a 5 × 5 factorial scheme, with three replicates, corresponding to sesame cultivars (BRS Seda, BRS G2, BRS G3, BRS G4 and BRS Anahi) and soil salinity levels with the following values for electrical conductivity: 0.6 dS m-1, 1.2 dS m-1, 1.8 dS m-1, 2.4 dS m-1 and 3.0 dS m-1. The physiological quality was characterized based on tests of germination, first germination count, germination speed index, radicle length, seed electrical conductivity, emergence, emergence speed index and seedling dry matter. BRS Seda, BRS G2 and BRS G3, cultivated under salinity levels, present seeds with a better physiological quality, demonstrating a higher tolerance to salt stress conditions. The BRS Seda and BRS G2 cultivars tolerate salinity levels of up to 2.4 dS m-1, while BRS G3 tolerates levels of up to 1.8 dS m-1. BRS G4 and BRS Anahi have the physiological quality of their seeds compromised by the increase in the soil salinity, during their production.

title: First mathematical model of cosmology: the concentric spheres of eudoxus

description: Abstract The cosmological model of Eudoxus of Cnidus (408 - 355 BC), the concentric spheres model, represents the first mathematical model of cosmology, which attempts to explain the motion of celestial bodies. Through the comments of Aristotle (384-322 BC), the writings of Simplicius (490-560 AD) and the approaches made by 19th century historians and mathematicians, the classical mathematical reconstruction of this model will be presented. We also use a modern mathematical method, the rotation matrix method, to illustrate the planetary motions that result from the Eudoxus model, and to determine the parametric equation of the hippopede. Due to the inexistence of the original historical records of the model, it is necessary to consider the main criticisms of this classic reconstruction of the nineteenth century, among them, the uniqueness of the reconstruction of the model. However, even with all the uncertainties in the reconstruction, over the centuries, the Eudoxus model presents itself as the first attempt to understand, with the observations and tools of mathematics of the time, the movements of the Sun, the Moon and the movements retrograde of the planets, and this work is dedicated to discuss these characteristics broadly, exhausting the main works presented in the literature.

title: Statin Treatments And Dosages In Children With Familial Hypercholesterolemia: Meta-Analysis

description: Abstract Background: Children with familial hypercholesterolemia may develop early endothelial damage leading to a high risk for the development of cardiovascular disease (CVD). Statins have been shown to be effective in lowering LDL cholesterol levels and cardiovascular events in adults. The effect of statin treatment in the pediatric population is not clearly demonstrated. Objective: To systematically review the literature to evaluate the effects of different statins and dosages in total cholesterol levels in children and adolescents with familial hypercholesterolemia. We also aimed to evaluate statin safety in this group. Methods: PubMed, EMBASE, Bireme, Web of Science, Cochrane Library, SciELO and LILACS databases, were searched for articles published from inception until February 2016. Two independent reviewers performed the quality assessment of the included studies. We performed a meta-analysis with random effects and inverse variance, and subgroup analyses were performed. Results: Ten trials involving a total of 1543 patients met the inclusion criteria. Our study showed reductions in cholesterol levels according to the intensity of statin doses (high, intermediate and low): (-104.61 mg/dl, -67.60 mg/dl, -56.96 mg/dl) and in the low-density lipoprotein cholesterol level: [-105.03 mg/dl (95% CI -115.76, -94.30), I2 19.2%], [-67.85 mg/dl (95% CI -83.36, -52.35), I2 99.8%], [-58.97 mg/dl (95% CI -67.83, -50.11), I2 93.8%. The duration of statin therapy in the studies ranged from 8 to 104 weeks, precluding conclusions about long-term effects. Conclusion: Statin treatment is efficient in lowering lipids in children with FH. There is need of large, long-term and randomized controlled trials to establish the long-term safety of statins.

title: Oxidation of Single-Walled Carbon Nanotubes under Controlled Chemical Conditions

description: Single-walled carbon nanotubes are oxidized in the presence of H2SO4/HNO3 mixtures containing distinct concentrations of the nitronium ion, [NO2+]. The spectroscopic analyses of the final samples suggest a higher structural disorder in the oxidized systems with increasing [NO2+]. This is due to a considerable oxygen amount on the tube surface, reaching up to 30%, depending on the reaction time and [NO2+]. Interestingly, if long reaction time is considered, the oxygen amount on the tube surface is maximum for low [NO2+] and reduces slightly for larger [NO2+]. On the other hand, the oxidation process occurs gradually at 4 h, allowing a fine control of the oxidation process. Therefore, if fine tuning of the oxidation degree is desirable, the reaction must be conducted during short time (4 h) using increasing [NO2+] as those obtained from 2:1, 2.5:1 and 3:1 H2SO4/HNO3 acid mixtures to produce increasing content of functionalization.

title: Potential area and limitations for the expansion of rainfed wheat in the Cerrado biome of Central Brazil

description: Abstract: The objective of this work was to locate and quantify, through geotechnologies, areas that are currently used for annual agriculture in the Cerrado biome of Central Brazil, located within the boundaries defined by the homogeneous region of adaptation of wheat cultivars 4 and that present favorable conditions for rainfed wheat (Triticum aestivum) cultivation. The following information layers were crossed: use and coverage of the Cerrado biome, digital elevation model, and water requirement satisfaction index for wheat in the Cerrado biome. In addition, different levels of water stress (low, moderate, and high), risk levels (20, 30, and 40%), available soil water capacities (ASWCs) (35, 55, and 75 mm), cultivar cycles (105, 115, and 125 days), and sowing dates (in February and March) were also considered. A greater favorable area was observed for sowing in early February, and group I of cultivars (105 days) presented the greatest favorable area. Above 800 m altitude, 2.7 million hectares were classified as favorable for the best combination of factors, i.e., sowing on February 5, ASWC of 75 mm, 105-day cycle, 20% risk level, and low and moderate impacts.

title: Prevalence of anxious and depressive symptoms in college students of a public institution

description: ABSTRACT Objective: Identify the prevalence of anxious and depressive symptoms and their correlations with sociodemographic and occupational characteristics in university students. Method: This is census, cross-sectional and analytical study, developed with nursing students of a federal public university in the Northeast of Brazil in the months of September and October 2016. 205 university students of all the periods of the course attended the study. Beck’s inventories for anxiety and depression were applied. Results: Most of the participants were female, single, native of the state capital and living with his parents. The prevalence of depression was 30.2% and of anxiety, 62.9%. Association between the level of depressive symptoms, work, sex and leisure was identified. Conclusion: The prevalence of symptoms of anxiety and depression was quite expressive, lacking, thus, more attention to the promotion of mental health of nursing students.

title: Anxiety and knowledge of patients before being subjected to orthognathic surgery

description: ABSTRACT Objective: to verify the correlation between anxiety level and degree of knowledge in patients before they are subjected to orthognathic surgery. Method: Descriptive cross-sectional study with 40 patients in the preoperative period before orthognathic surgery of a private clinic in the city of São Paulo. Results: IDATE-trait anxiety levels feature prevalence of medium-level anxiety with 72.5% (n=29), followed by low-level anxiety with 72.5% (n=29) and high-level level anxiety with 10% (n=4). In the pre-operative period, transitory IDATE-state anxiety levels feature medium-level anxiety with 65% (n=26), followed by high-level anxiety with 22.5% (n=9) and low-level anxiety with 10% (n=4). Pearson’s correlation coefficient resulted in negative r (−0.2) for anxiety-trait (p 0.197) and in negative r (−0.1) for anxiety-state (p 0.417). Conclusion: The data shows a weak correlation in which greater knowledge about the surgical procedure reduces levels of anxiety that may be related to the absence of appropriate guidance about the surgical procedure.
