title: Transpiration Reduction Factor and Soybean Yield in Low Land Soil with Ridge and Chiseling

description: ABSTRACT Water and oxygen deficiencies in the soybean crop cultivated on lowland soils are an important topic of research. The objective of this study was to investigate changes in water and oxygen supply and soybean yield caused by soil management in lowland soils. A soybean crop was grown under four soil conditions: no-tillage (NT), chiseling (CH), ridge tillage on no-tillage (NTR), and ridge tillage on chiseling (CHR). Soil bulk density, total porosity, macro- and microporosity, air permeability, and saturated hydraulic conductivity were measured at 0.05, 0.15, 0.25, and 0.35 m depths. Soil volumetric water content was monitored at the same depths every 30 min during the soybean cycle. The transpiration coefficient was calculated from volumetric water content to express both water and oxygen deficiency. The groundwater level was monitored throughout the soybean cycle. Plant performance was evaluated by measuring plant population, shoot dry matter, yield, and taproot depth. Soil porosity, air permeability, and saturated hydraulic conductivity were most improved in CH and CHR, and less in NTR. Nonetheless, expected improvement in soil aeration in CH, CHR, and NTR was eliminated when the water table raised to near the soil surface. The transpiration coefficient indicated that CH decreased oxygen deficiency, but caused little water deficit. The CH also provided the highest yield (4,610 kg ha-1), which was not surpassed by the addition of ridge tillage on chiseled soil (CHR) (4,001 kg ha-1). The lowest yields were observed in NT (2,842 kg ha-1), and NTR (3,565 kg ha-1), in which oxygen deficiency was more severe. Lower oxygen deficiency for soybean in chiseled lowland soil is regulated by the water table. As the transpiration coefficient is dependent on all the processes determining soil water dynamics, it is more informative than soil structural properties regarding water and oxygen deficiency in soybean in lowland soil.

title: GENETIC DIVERSITY AND STRUCTURE OF MACAW PALM: IMPLICATIONS FOR GENETIC VARIABILITY SAMPLING

description: ABSTRACT The macaw palm, Acrocomia aculeata (Jacq.) Lodd. ex Mart., is a Brazilian native species with great potential for biofuel production. The aim of this work was to analyze macaw palm genetic diversity to structure and assist in the definition of sampling strategies for germplasm banks. Forty-six microsatellite markers, from which seven polymorphic markers were used to evaluate 103 macaw palm individuals collected from different Brazilian locations. The polymorphic markers were used to generate a dissimilarity matrix by weighted index. The imaging of genetic variability was realized by 3D projection of matrix dissimilarity. Sixty-seven individuals had their ITS region sequenced and aligned, and the mutations found were used to generate a haplotype network. The average genetic distance identified between individuals was 76.2%, ranging from 3.7 to 100%. Genetic variability structure was not found. ITS region sequencing of the 67 individuals revealed four polymorphic sites, defining four haplotypes. The results of this study suggest that historically, macaw populations were strongly connected, indicating a recent population expansion of the species. The results indicate that macaw genetic variety sampling should focus on effective collection in selected locations. Areas such as Caatinga and Humid Chaco however, could present new sources of genetic variability, and should be studied.

title: SPECTRUM AND VELOCITY OF DROPLETS OF SPRAY NOZZLES WITH AND WITHOUT AIR INDUCTION

description: ABSTRACT The aim of this study was to evaluate the spectrum and the velocity of droplets produced by nozzles with and without air induction, under different pressures and flow rates. The experiment was conducted in a completely randomized design with five replications, in a factorial 2 x 3 x 3 (two spray nozzles, three flow rates and three operating pressures). The spray nozzles with and without air induction of the Hypro manufacturer (GA and VP) were evaluated, with nominal flow rates of 0.76; 1.14 and 1.51 L min-1 and pressures of 200, 300 and 400 kPa. The spectrum and velocity of the droplets were determined directly, using a Visisize Portable P15 (Oxford Lasers, Imaging Division). The pressure increases further reduction of the VMD and the relative amplitude, and increases the droplet velocity. The droplets generated by the spray nozzles with air induction showed on average amplitude 1.54 times higher than the droplets generated by spray nozzles without air induction. The droplet velocity showed little variation between the nozzles with and without air induction with the same pressure and flow rate, however, spray nozzles with larger flow rates and pressures produced droplets with higher velocities.

title: Pellucid marginal degeneration: postponing penetrating keratoplasty for over a decade

description: Abstract Pellucid marginal degeneration (PMD) treatment can be challenging in moderate to advanced cases and penetrating keratoplasty should be avoided due to high risk of complications, such as graft rejection. We report a case of a 30-year-old female patient with PMD that was referred to our service with bilateral low visual acuity, worse in her right eye and contact lenses intolerance. We performed a corneal crescentic lamellar wedge resection that resulted in good useful vision and postponed the keratoplasty for eighteen years.

title: A Practical Fluorescence-Based Screening Protocol for Polyethylene Terephthalate Degrading Microorganisms

description: We propose a practical, low-cost and selective fluorescence-based protocol adapted to identify polyethylene terephthalate (PET) degrading microorganisms. The microbial hydrolysis of PET nanoparticles was monitored by 2-hydroxyterephthalate, a fluorophore produced in situ after radical hydroxylation of terephthalic acid (TPA), the final hydrolysis product, by the Fenton reaction. Seven fungi presenting promising PET hydrolytic potential using the proposed microscale screening assay were identified. The strains evaluated presented a substantial increase of up to 18-fold in PET nanoparticles conversion, such as obtained by the fungus Trichoderma sp. C70, after their cultivation in a PET-enriched medium. The formation of other hydrolysis products, along with TPA, was observed using matrix assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS).

title: OPERATOR EFFORT ON THE OPERATION OF THE KNAPSACK SPRAYER PUMPING LEVER

description: ABSTRACT Several equipments are used in the application of agrochemicals by small scale farmers, with emphasis on the knapsack hand sprayer due to the low cost of acquisition and viability of use in different operating conditions. Although it is an equipment widely used, few studies have been developed in order to ascertain its functional characteristics. This study has the objective of presenting a methodology to measure the effort to which the operator is subjected in the activation of the pumping lever of knapsack hand sprayer verifying if these machines fit within the limitations foreseen by the Brazilian laws and international regulations. The methodology used was adequate to measure the operator's required efforts for the activation of knapsack hand sprayer. All sprayers tested with water have achieved satisfactory results by national standards, but only two by international regulations.

title: Internal carotid artery aneurysm mimicking normal-tension glaucoma

description: ABSTRACT Differentiating glaucomatous from nonglaucomatous optic disc cupping remains challenging. We present a case of a 48-year-old woman with an internal carotid aneurysm of approximately 3.5 mm × 6.5 mm that mimicked normal-tension glaucoma. The patient had a 2-year history of low vision acuity in her left eye and frontal oppressive headache. Owing to the carotid aneurysm, she developed an asymmetric vertical cup-to-disc ratio above 0.2, and marked inferotemporal neuronal rim loss and pallor of the residual rim were noted in the left disc. She also developed a visual field defect with an arcuate scotoma in the left eye. The patient was referred to a neurosurgeon and underwent endovascular aneurysm occlusion. This case highlights the diagnostic importance of recognizing that many neurological defects remain underdiagnosed.

title: Analysis of the frequency of uveitis in spondyloarthritis patients and associations with clinical parameters of the disease

description: Abstract Objective: Acute anterior uveitis (AAU) is the most common extra-articular manifestation of spondyloarthritis. The aim of this study is to analyze if the presence of uveitis is associated with a diferent clinical manifestation, laboratorial, radiological and therapetiuc among spondyloarthritis patients. Methods: This was a observational retrospective study with 153 patients with spondyloarthritis attended in the period from 1997 to 2017 in Florianopolis, Brazil. It was analyzed demografical, laboratorial, clinical and therapeutic data in spondyloarthritis patients with or without uveitis. Results: 26,8% of the patients with spondyloarthritis presented uveitis. The presence of complications was rare, with cataract occurring in only four patients and glaucoma in two of them. A higher frequency of acute anterior uveitis in males (p = 0.06) was observed in patients with a family history (p = 0.19) and HLA-B27 positive (p = 0.14). Patients with spondyloarthritis and uveitis more frequently used anti-TNF (p = 0.04) and presented sacroiliitis on imaging tests (p = 0.02). There was no association between uveitis and cardiovascular (p = 0.44), cutaneous (p = 0.13) or gastrointestinal involvement (p = 0.10). Conclusion: Uveitis in patients with spondylarthritis is common, predominantly in males, and more frequently in HLA-B27 positive patients. The use of immunobiological agents such as anti-TNF is common in patients with uveitis.

title: Technical Indicators registered as a function of the playing time in Brazilian basketball

description: Abstract Basketball performance analysis using technical indicators dissociated from the moment they occurred in the game seems to no longer respond to emerging issues of the game as it does not identify the periods when a team’s offensive efficiency has increased or decreased. The aim was to characterize and compare the technical indicators in the positive and negative periods and in the whole game of winning and losing teams in men’s professional basketball. Fourteen games of professional men’s teams of the “Novo Basquete Brasil” Championship in the regular 2011/2012 season were filmed and analyzed. The Kolmogorov-Smirnov test was used to verify data normality. The independent T test was used for variables with normal distribution and the Mann-Whitney test for variables that did not present normal distribution, in order to compare teams’ performance. Analysis in the whole game showed that winning teams had significantly higher averages in successful 3-point field goals but in the positive periods, they showed higher averages for successful free throws, successful layups, defensive rebounds and defensive fouls, and in negative periods, losing teams made more defensive and offensive fouls. The teams’ performance in the whole game may not elucidate the determinant indicators for building the difference in the scoreboard. It is suggested that coaches should identify the periods of best and worst teams’ performance in the game and the indicators involved, preparing teams to overcome the negative periods and obtain more positive periods in the game.
