title: Tomato yield as a function of water depths and irrigation suspension periods

description: ABSTRACT Irrigation management is essential for tomato fruits yield and quality. Therefore, the aim of this study was to evaluate the yield of tomatoes for industrial processing, ‘BRS Sena’ hybrid, subjected to water depths and irrigation suspension periods before harvest, irrigated by subsurface drip irrigation, in Goiás, Brazil (17º 49’ 19.5” S and 49º 12’ 11.3” W), in 2015 and 2016. The experiments were conducted under a randomized complete block design, with four replications, in split plots. Five irrigation levels (50, 75, 100, 125 and 150% of crop evapotranspiration) were evaluated in the plots and five irrigation suspension periods (0, 7, 14, 21 and 28 days before harvest) were evaluated in the subplots. At 125 days after transplanting the seedlings, the yields of green, mature, rotten fruits and total yield, water productivity and percentages of green, mature and rotten fruits were evaluated. The highest total fruit yields (105.86 and 58.60 t ha-1) were obtained with water replacements ranging from 125.47 (615.09 mm) to 132.11 (564.00 mm) of crop evapotranspiration, in the first and second year of experiment, respectively. Growing plants under water deficit and excess increased the incidence of rotten fruits and decreased that of mature fruits. Pre-harvest irrigation suspension reduced crop yield and incidence of green fruits and increased the incidence of rotten fruits. The highest water productivity by the crop occurred under water deficit, management that may be interesting for regions with water restrictions.

title: Phosphorus sources associated with organic compound in broccoli production and soil chemical attributes

description: ABSTRACT Phosphorus is a finite natural resource and the use of gradual-release phosphate sources, associated with an organic compound may favor a more rational use of this nutrient, since organic matter protects P from soil fixation. The aim of this study was to evaluate the effect of phosphorus sources application, associated with organic compound at planting, on single inflorescence type broccoli production and soil chemical properties at the end of the cycle. Eight treatments were evaluated, in a 4 x 2 factorial scheme, using four phosphorus sources [thermophosphate (TM), natural phosphate (NP), reactive natural phosphate (RNP) and triple superphosphate (TSP)]; in the presence (55 t ha-1) and absence of organic compound Visafértil® at planting. The experimental design was randomized blocks, with four replicates. TSP source presented higher P contents. TM source showed, in the absence of organic compound, higher pH and contents of organic matter, Ca, Mg, SB and V%. In the presence of organic compound, NP source provided higher contents of organic matter and K. The addition of organic compound increased pH and resulted in higher contents of P, K, Ca, SB, CEC and V%. The presence of organic compound favored higher productivity for the sources TM, NP and TSP. Among these sources, TSP provided the highest production both in the presence or absence of organic compound, considering that NP source was the only one which did not differ from TSP for inflorescence fresh weight and productivity, both in the presence and in the absence of organic compound. We concluded that TSP and NP are the best P sources, associated with the application of organic compound.

title: ELEPHANT GRASS (Pennisetum purpureum Schumach) IS A PROMISING FEEDSTOCK FOR ETHANOL PRODUCTION BY THE THERMOTOLERANT YEAST Kluyveromyces marxianus CCT 7735

description: ABSTRACT Elephant grass (Pennisetum purpureum Schumach) is regarded as a promising feedstock for second generation ethanol production, due to its high cellulose content, biomass production and rapid growth. The yeast Kluyveromyces marxianus CCT 7735 is capable of producing ethanol from agroindustrial residues, such as lignocellulosic biomass. Therefore, this study aimed to establish the optimal conditions for ethanol production by K. marxianus CCT 7735 from elephant grass. Five factors were evaluated: temperature (35-45 ºC), pH (4.5-5.8), agitation (50-150 rpm), cellulase concentration (7.5-22.5 FPU/mL) and elephant grass biomass (8-16% w/v). Enzymatic concentration (22.5 FPU/mL), biomass concentration (16% w/v) and temperature (38 ºC) were the significant optimized factors. K. marxianus CCT 7735 produced a high ethanol concentration (around 45.5 g/L) under these optimized conditions, which is considered feasible in terms of energy requirements in the distillation step.

title: Shear strength analysis of slabs without transverse reinforcement under concentrated loads according to ABNT NBR 6118:2014

description: Abstract Concentrated loads in slabs without transverse reinforcement, usual in highway bridges, result in the horizontal spreading of the shear force towards the supports, situation in which not all the slab width contributes in the shear strength. Based on this, the analytical models of shear strength and punching capacity in slabs may not be suitable to deal with this loading. Since this topic is not widely discussed in the national technical literature, the paper aims to present contributions to these analyses with a focus on the accuracy level of the shear strength analytical models recommended by ABNT NBR 6118:2014. Therefore, the models available in the Brazilian code were applied to an experimental database with 118 test results and the results obtained by the Brazilian and European codes were compared. The results demonstrated that, as presented in the Brazilian code, shear strength model in one-way slabs can lead to unsafe resistance predictions while the punching capacity model can lead to very conservative predictions. From the analysis, it is concluded that considering the reduction of the shear force, in the case of loads distributed in small areas close to the support in slabs, and the use of more suitable procedures to define the effective width, it is possible to improve the level of accuracy of relations between experimental and theoretical values, but this still leads to high percentages of unsafe predictions of resistance (&gt; 40%).

title: A Influência da Reeleição nas Políticas Fiscais Subnacionais

description: Abstract This paper presents an empirical investigation on the potential effect of the end of the executive branch’s reelection on municipalities’ public finances. An econometric analysis based on a panel of Brazilian cities from the year 2001 up to 2012 shows that first-term mayors that compete for reelection are more fiscally responsible when compared to second-term mayors or first-term mayors that don’t compete for reelection. This result confirms the existing literature on career concerns, which suggests that reelection works as an instrument that voters can use in order to control the fiscal behavior of elected executive incumbents. Moreover, it highlights the risk of excessive subnational budgetary deficits in case reelection is forbidden in Brazil.

title: Inter-municipal cooperation in Latin America: current situation and future research challenges

description: Abstract This article offers an overview of Latin American research on inter-municipal cooperation, a phenomenon that has gained empirical relevance in the region since the 1990s. Based on a systematic literature review and content analysis of 47 articles published between 2005 and 2016 selected from indexed journals (WOS, Scopus, and LatinIndex), this article reports the progress of research, the complexities of the operation, and the different effects of inter-municipal cooperation in Latin American countries. The results identify the main gaps in studies about causes and determinants of ‘collaboration’ as an organizational model and territorial governance, as well as the lack of studies on the effectiveness of these arrangements. By identifying these gaps it is possible to guide the future research agenda on cooperation between municipalities.

title: Robotic Mitral Valve Surgey Combined with Left Atrial Reduction and Ablation Procedures

description: Abstract Introduction: This study aimed to evaluate the feasibility and efficacy of robotically assisted, minimally invasive mitral valve surgery combined with left atrial reduction for mitral valve surgery and elimination of atrial fibrillation (AF). Methods: Eleven patients with severe mitral regurgitation, AF, and left atrial enlargement who underwent robotic, minimally invasive surgery between May 2013 and March 2018 were evaluated retrospectively. The da Vinci robotic system was used in all procedures. The patients’ demographic data, electrocardiography (ECG) findings, and pre- and postoperative transthoracic echocardiography findings were analyzed. During follow up ECG was performed at postoperative 3, 6, and 12 months additionally at the 3rd month trans thoracic echocardiography was performed and functional capacity was also evaluated for all patients. Results: All patients underwent robotic-assisted mitral valve surgery with radiofrequency ablation and left atrial reduction. Mean age was 45.76±16.61 years; 7 patients were male and 4 were female. Preoperatively, mean left atrial volume index (LAVI) was 69.55±4.87 mL/m2, ejection fraction (EF) was 54.62±8.27%, and pulmonary artery pressure (PAP) was 45.75±9.42 mmHg. Postoperatively, in hospital evaluation LAVI decreased to 48.01±4.91 mL/m2 (P=0.008), EF to 50.63±10.13% (P&gt;0.05), and PAP to 39.02±3.11 mmHg (P=0.012). AF was eliminated in 8 (72%) of the 11 patients at the 1st postoperative month. There were significant improvements in functional capacity and no mortality during follow-up. Conclusion: Left atrial reduction and radiofrequency ablation concomitant with robotically assisted minimally invasive mitral valve surgery can be performed safely and effectively to eliminate AF and prevent recurrence.

title: Time of metamitron application and concentration in the chemical thinning of ‘Maciel’ peach

description: Abstract In the peach tree cultivation, the producer has the challenge of obtaining good quality fruits and maintaining production in a balanced way over the years. Thinning favors these parameters and reduces the fruit load on plants. Manual thinning commonly practiced on peach trees requires high labor and increases production costs. Chemical thinning as an alternative to manual thinning, which depending on the species, time and concentration, has demonstrated high efficiency. The aim of this study was to evaluate the effect of metamitron applied at different seasons and concentrations on the chemical thinning of peach trees in southern Brazil. Experiments were conducted in a commercial peach orchard (‘Maciel’ cultivar), in the municipality of Morro Redondo, Rio Grande do Sul, Brazil, during the 2015 and 2016 harvests. In experiment 1, metamitron at concentration of 200 mg L-1 was applied at 20, 30, 40, 50 and 60 days after full bloom and manual thinning performed at 40 days after full bloom. In experiment 2, metamitron was applied at concentrations of 100 mg L-1, 200 mg L-1, 300 mg L-1 and 400 mg L-1 and manual thinning at 40 days after full bloom, in addition to control plants. Fruit abscission, fruit set, total number of fruits per plant, yield per plant, average mass and fruit diameter were evaluated. Metamitron at concentration of 200 mg L-1 has thinning effect when applied before 40 days after full bloom. Metamitron concentration of 100 mg L-1 applied at 40 DAFB promoted fruit abscission superior to manual thinning. Therefore, the application of metamitron to ‘Maciel’ peach trees close to full bloom at concentration of 100 mg L-1 results in thinning practice similar to manual thinning.

title: Impact of Arterial Procedures on Coagulation and Fibrinolysis - A Pilot Study

description: Abstract Objective: The main goal of our study was to assess the impact of vascular procedures on the activity of hemostatic and fibrinolytic pathways. Methods: We enrolled 38 patients with ≥ 45 years old undergoing surgery for abdominal aortic aneurysm or peripheral artery disease under general or regional anesthesia and who were hospitalized at least one night after the procedure. Patients undergoing carotid artery surgery and those who had acute bypass graft thrombosis, cancer, renal failure defined as estimated glomerular filtration rate &lt; 30 ml/min/1.73m2, venous thromboembolism three months prior to surgery, or acute infection were excluded from the study. We measured levels of markers of hemostasis (factor VIII, von Willebrand factor:ristocetin cofactor [vWF:CoR], antithrombin), fibrinolysis (D-dimer, tissue plasminogen activator [tPA], plasmin-antiplasmin complexes), and soluble cluster of differentiation 40 ligand (sCD40L) before and 6-12h after vascular procedure. Results: Significant differences between preoperative and postoperative levels of factor VIII (158.0 vs. 103.3, P&lt;0.001), antithrombin (92.1 vs. 74.8, P&lt;0.001), D-dimer (938.0 vs. 2406.0, P=0.005), tPA (10.1 vs. 12.8, P=0.002), and sCD40L (9092.9 vs. 1249.6, P&lt;0.001) were observed. There were no significant differences between pre- and postoperative levels of vWF:CoR (140.6 vs. 162.8, P=0.17) and plasmin-antiplasmin complexes (749.6 vs. 863.7, P=0.21). Conclusion: Vascular surgery leads to significant alterations in hemostatic and fibrinolytic systems. However, the direction of these changes in both pathways remains unclear and seems to be different depending on the type of surgery. A study utilizing dynamic methods of coagulation and fibrinolysis assessment performed on a larger population is warranted.

title: AUTISM SPECTRUM DISORDER AND POSTNATAL FACTORS: A CASE-CONTROL STUDY IN BRAZIL

description: ABSTRACT Objective: To estimate the magnitude of the association between Autism Spectrum Disorder (ASD) and postnatal factors in a Brazilian population. Methods: A case-control study was performed with 253 individuals diagnosed with ASD and 886 individuals without signs of the disorder. A semi-structured questionnaire and the multiple logistic regression model were adopted in the data analysis. To estimate the magnitude of associations, the crude and adjusted Odds Ratio (OR) was used. Results: An association with the following factors was found: having been born with congenital malformation (OR 4.24; confidence interval of 95% - 95%CI 1.92-9.34), neonatal jaundice (OR 1.43; 95%CI 1.01-2.02), absence of crying at birth and seizure episode in childhood (OR 5.75; 95%CI 3.37-9.81). The magnitude of the association was higher in the children/adolescents who had two or more postnatal complications (OR 6.39; 95%CI 4.10-10.00). Conclusions: The findings of the present study suggest that malformation, neonatal jaundice, absence of crying at birth and seizure episodes in childhood are important factors to be considered when studying the etiology of ASD.

title: Is allergic rhinitis related to migraine disability in adults?

description: ABSTRACT Migraine is a chronic condition with complex pathophysiology. Although immunologic disturbances have been linked to migraine, only few attempts have been made to assess the possibility of allergic rhinitis as a worsening factor of migraine in adults. Objective This survey aimed to compare migraine disability between adult migraineurs with and without current allergic rhinitis. Methods This cross-sectional study comprised 118 adult migraineurs who were consecutively assisted at an outpatient clinic. After ordinary neurological evaluation, participants were evaluated for headache disability using the Migraine Disability Assessment (MIDAS). The presence of current allergic rhinitis, allergic rhinoconjunctivitis and seasonal allergic rhinitis was scored for each participant according to the International Study of Asthma and Allergies in questionnaire. Results There was no significant difference between the MIDAS scores of those with current allergic rhinitis, allergic rhinoconjunctivitis, or seasonal allergic rhinitis and nonatopic migraineurs. The disability caused by allergic symptoms also did not influence the MIDAS scores of patients with allergic rhinitis. The frequency of headache days during the last three months was higher in the subset of patients without allergic rhinitis (median and interquartile range 12 [8–19.2] vs. 8 [4–14]; p = 0.03). Conclusions Our results suggest that current allergic rhinitis, allergic rhinoconjunctivitis, and seasonal allergic rhinitis are not related to headache disability in adults with episodic migraine.
