title: Characterization of cowpea cultivars for grain size, color, and biofortification

description: ABSTRACT Cowpea crops have high socioeconomic importance in the Northeast region of Brazil. These crops generate employment and income; in addition, it is an excellent source of protein, minerals, vitamins, and dietary fiber, and contributes to the food security of thousands of people. Biofortification of cowpea with iron, zinc, and proteins can contribute to prevent the higher hunger. The objective of this work was to assess iron, zinc, and protein contents in cowpea grains of different cultivars and the effect of grain size and color on the contents of these nutrients. Twenty-four cultivars with variation in size and color of the seed coat were evaluated. Iron contents ranged from 7.12 to 8.60 mg 100 g-1, with an overall mean of 7.75 mg 100 g-1. Zinc contents ranged from 4.46 to 4.93 mg 100 g-1, with an overall mean of 4.71 mg 100 g-1. Protein contents ranged from 31.50 to 36.24 g 100 g-1, with an overall mean of 33.57 g 100 g-1. Grain size ranged from 13.55 to 37.88 g, with an overall mean of 21.50 g. The cultivars Caldeirão, BRS-Guariba, and Pingo-de-Ouro-1-2 have higher iron contents; BRS-Aracê and BRS-Imponente have higher zinc contents; BR-14-Mulato, BRS-Guariba, BRS-Aracê, and BRS-Inhuma, have higher protein contents; and BR-3-Tracuateua and BRS-Imponente have larger grain sizes. The size and color of the seed coat do not influence the iron, zinc and protein contents of the evaluated cowpea cultivars.

title: Adaptability and stability of corn hybrids for the south of the Amazon biome via GGE biplot

description: Abstract The objective of this work was to select maize hybrids using the GGE biplot analysis, as well as to evaluate their stability and adaptability in different environments of the North and Midwest regions of Brazil. Thirty-six maize hybrids were evaluated in 2018, in the following five environments in the Northern and Midwestern regions, respectively: in the municipality of Vilhena, in the state of Rondônia; and in the municipalities of Sorriso, Sinop, Alta Floresta, and Carlinda, in the Northern region of the state of Mato Grosso. The experimental design was a randomized complete block design. The analysis of variance was performed, and adaptability and stability were estimated by the GGE biplot method based on grain yield performance. A significant interaction between genotypes and environments was detected, and the biplot analysis was efficient in explaining 62.74% of the total variation in the first two principal components, with the formation of three macroenvironments. The 1P2227, 'BRS 3042', and 1P2265 hybrids showed high yield, responsiveness, and stability in the evaluated environments. The DKB310VTPRO2 hybrid was the most unstable genotype. The recommended hybrids are: DKB310 for the Sorriso and Vilhena macroenvironment; 1M1810 and 1O2106 for the Carlinda environment; and 1M1807 for the Sinop environment.

title: RECOVERING PROBABILITY FUNCTIONS WITH FOURIER SERIES

description: ABSTRACT The COS method was introduced in Fang & Oosterlee (2008) and then was applied to pricing a variety of stock options for continuous random variables. This paper adapts the Fourier-cosine series (COS) method to recover discrete probability mass functions. We approximate mixture and compound probability distributions with cosine series. Enormous precision and computational speed are the qualities of the function estimates here obtained. We also develop the pricing framework to trade derivatives subject to discrete random variables. We apply the method to calculate, for the first time, the price of an interest rate derivative of recent vintage introduced in the Brazilian financial market. Parameter calibration confirms the quality of the model.

title: Democracy through the spirit: the Universal Church and its interconnections with Brazilian democracy

description: Abstract The connection between Evangelical church actors and contemporary Brazilian federal politics has raised many speculations, especially regarding the association of these churches with neoliberalism and populist governments. In a different manner, this article aims to show how churches from the third wave of Pentecostalism, and the Universal Church in particular, engage in the most recent historical phase of Brazilian democracy that began in the late 1980’s. The grow of Universal Church and the democratic development of Brazil are investigated in parallel here, giving light to the different political connections and arrangements this church has been part of in the last decades. This makes it possible to understand what the alliances between the Universal Church and the country’s presidency actually mean for both the church institution and its common members.

title: The Use of Intraoperative Extracorporeal Membrane Oxygenation in Lung Transplantation: Initial Institutional Experience

description: ABSTRACT Introduction: Lung transplantation is the final treatment option for end-stage lung disease, and extracorporeal membrane oxygenation (ECMO) is increasingly being used during lung transplantation. Objective: The present study aimed to review our initial experience with patients who underwent lung transplantation with or without ECMO since the implementation of the lung transplantation program at our center. Methods: Data were prospectively collected on all patients between December 2016 and December 2018. Patients undergoing ECMO as a bridge to lung transplantation were excluded. Results: A total of 48 lung transplants were performed, and ECMO was used in 29 (60.4%) cases. Twenty (83%) patients were female. The median age was 48.5 (range, 14-64) years. The most common indications were idiopathic interstitial pneumonia in 9 (31%) patients, chronic obstructive pulmonary disease in 7 (24.1%) patients, and bronchiectasis in 6 (20.7%) patients. Sequential bilateral lung transplantation was performed in all patients. The 30-day mortality was 20.6% (6/29) for patients with ECMO, however, it was 10.5 (2/19) for patients without ECMO (P=0.433). The median length of stay in the intensive care unit (ICU) was 5 (range, 2-25) days. The ECMO weaning rate was 82.8% (24/29). One-year survival was 62.1% with ECMO versus 78.9% without ECMO, and the 3-year survival was 54.1% versus 65.8%, respectively (P=0.317). Conclusions: ECMO is indicated for more severe patients who underwent lung transplantation. The use of ECMO provides adjuvant support during surgery and the mortality rate is acceptable. Survival is also as similar as non-ECMO patients. ECMO is appropriate for critically ill patients.

title: Management of mechanized harvesting through operational modeling

description: ABSTRACT The activity of agricultural experimentation may require high budget and long periods of time for obtaining data. Due to production features, decision-making processes within agro-industrial mills that use sugarcane as raw material must be optimized. In this scenario, modeling operating systems that use embedded technology as agricultural automation enables the optimization of decision-making and influences operational performance and costs. This article presents a model for receiving and processing sugarcane based on its harvesting capacity, considering the harvestability index and the nominal capacity of the harvester. Sensitivity analysis enables the assessment of potential offenders and the reallocation of assets, thus optimizing resources and ensuring plant operation. This analysis also enables new possibilities, such as harvesting under different row spacings and harvesting simultaneously different rows.

title: Endo-β-mannanase and superoxide dismutase as enzymatic markers for lettuce seeds thermotolerance

description: Abstract: At higher temperatures, lettuce seeds may not germinate, resulting in problems for crop establishment in the field and production. This study aimed to evaluate the maternal effect for thermotolerance on lettuce seeds and find enzymatic markers. We used the thermoinhibition tolerant cultivar ‘Everglades’, the sensitive ‘Verônica’, their reciprocal hybrids, F1 and F2 generation. Seeds were submitted to germination and enzymatic tests (catalase, superoxide dismutase, ascorbate peroxidase, and endo- β-mannanase). Germination (first and final counting) and speed index were compared through Tukey’s test. ‘Everglades’ and its reciprocal hybrids, have not been influenced by temperature regarding germination compared to the other treatments. Also, the maternal effect was observed for the F1 generation. Higher temperatures interfere with the activity of all enzymes evaluated, consequently in the physiological parameters. However, superoxide dismutase and endo- β-mannanase have shown direct and more expressive correlation with changes on the physiological parameters compared to the other enzymes. Thus, it is possible to conclude that those enzymes can be used as markers for thermotolerant genotype selection.

title: Adaptation, calibration, and validation of the agro-ecological zone model for Urochloa humidicola pastures

description: ABSTRACT The agro-ecological zone model (AZM-FAO) is used to describe agricultural scenarios and the impact of climate risk on crops and, when adapted, can be used to simulate the yield of forage species under adverse conditions. The study aimed to test the performance of the AZM-FAO model to simulate the yield of Urochloa humidicola grass in Mato Grosso. The model was adapted for two locations with different soil and climate conditions, with data from two experiments (E1 and E2). The morphophysiological variables of the pastures, the physical-hydric variables of the soil, and the meteorological data of the experimental period were analyzed. The model calibration was based on changes in the yield response coefficient to water (Ky) and the minimization of deviations between simulated and observed data. The model presented a satisfactory performance for the two analyzed locations. In experiment E1, the RMSE was 29.86% (acceptable), and the c index was 0.86 (optimal) in the calibration phase, maintaining the same results in the validation. In E2, there was an improvement in the performance of the model, with RMSE and c index going from 30.74% (poor) and 0.84 (very good) in the calibration to 17.50% (good) and 0.92 (very good) in the validation step, respectively. The AZM-FAO model adapted for Urochloa humidicola grass can be used with good accuracy to simulate the forage yield of this forage in the southern region of Mato Grosso.
