The limestone with smaller particle size provides rapid correction of soil acidity. However, the limestone with large particles can promote bigger root growth, and may still have a residual effect on the soil. The aim of this study was to evaluate the residual effect of the application and incorporation of different limestone with a particle size bigger than 0.30 mm in root growth, nutrition and yield of maize in Cerrado soil. A randomized completed block utilized in this experiment, with five treatments and four replications. The grain sizes of dolomitic limestone incorporated into the Oxisol were: 0 (control, no-lime), 2.00-0.82 mm, 0.82-0.56 mm, 0.56-0.30 mm, 0.30-0.20 mm, in doses of 6.5 t·ha-1, 3.9 t·ha-1, 2.6 t·ha-1 and 1.3 t·ha-1 respectively. The limestone applied in introduction no-tillage. The maize were evaluated of root attributes, nutrition and grain yield in two years 2009 and 2010. The use of limestone particle size of 2.00-0.82 mm, and the quantity of 6.5 t·ha-1 applied to the soil and incorporated showed elongation and root growth of maize thin depth of 20-40 cm in the soil. In that, same proposed management of the limestone was the highest maize grain yield in the first year. The rooting characteristics evaluated correlated with leaf Ca and Cu and maizegrain yield.

AIM： To analyze the risk of cardiovascular complications in patients with indication for surgical treatment of Chagasic esophageal achalasia and to correlate the surgical risks with the degree of esophageal dilation, thereby proposing a risk scale index. METHODS： One hundred and twenty-four patients with Chagasic esophageal achalasia, who received surgical treatment at the Hospital das Clinicas of the Federal University of Goiás, were included in this study. The patients were mostly related to the postoperative complications due to the cardiovascular system. All the patients were submitted to：（1） clinical history to define the cardiac functional class （New York Heart Association）; （2） conventional 12-lead electrocardiogram at rest; and （3） contrast imaging of the esophagus to determine esophageal dilatation according to Rezende＇s classification of Chagasic megaesophagus. RESULTS： An assessment of the functional classification （FC） of heart failure during the preoperative period determined that 67 patients （54.03%） were assigned functional class Ⅰ （FC Ⅰ）, 46 patients （37.09%） were assigned functional class Ⅱ （FC Ⅱ）, and 11 patients （8.87%） were assigned functional class Ⅲ （FC Ⅲ）. None of the patients were assigned to functional class Ⅳ （FC Ⅳ）. There was a positive correlation between the functional class and the postoperative complications （FC Ⅰ×FC Ⅱ： P〈0.001; FC Ⅰ×FC Ⅲ： P〈0.001）. The ECG was normal in 44 patients （35.48%） and presented abnormalities in 80 patients （64.52%）. There was a significant statistical correlation between abnormal ECG （arrhythmias and primary change in ventricular repolarization） and postoperative complications （P〈0.001）. With regard to the classification of the Chagasic esophageal achalasia, the following distribution was observed： group Ⅱ, 53 patients （42.74%）; group Ⅲ, 37 patients （29.83%）; and group Ⅳ, 34 patients （27.41%）. There was a positive correlation between the degree of esophageal dilation and the increase in postoperative compli

Acoustic sensing is nowadays a very demanding field which plays an important role in modern society, with applications spanning from structural health monitoring to medical imaging. Fiber-optics can bring many advantages to this field, and fiber-optic acoustic sensors show already performance levels capable of competing with the standard sensors based on piezoelectric transducers. This review presents the recent advances in the field of fiber-optic dynamic strain sensing, particularly for acoustic detection. Three dominant technologies are identified - fiber Bragg gratings, interferometric Mach-Zehnder, and Fabry-Perot configurations - and their recent developments are summarized.

Acoustic emission monitoring is often used in the diagnosis of electrical and mechanical incipient faults in the high voltage apparatus. Partial discharges are a major source of insulation failure in electric power transformers, and the differentiation from other sources of acoustic emission is of the utmost importance. This paper reports the development of a new sensor concept - a fiber laser sensor based on a phase-shifted chirped fiber grating - for the acoustic emission detection of incipient faults in oil-filled power transformers. These sensors can be placed in the inner surface of the transformer tank wall, not affecting the insulation integrity of the structure and improving fault detection and location. The performance of the sensing head is characterized and compared for different surrounding media： air, water, and oil. The results obtained indicate the feasibility of this sensing approach for the industrial development of practical solutions.

AIM： To examine genetic variation of nucleotide oligomerization domain 1 （NOD/） and NOD2, their respective influences on Crohn＇s disease phenotype and gene-gene interactions. METHODS：（ND1＋32656＊1） NOD1 polymorphism and SNPS, SNP12 and SNP13 of NOD2 were analyzed in 97 patients and 50 controls. NOD2 variants were determined by reaction restriction fragment length polymorphism analysis. NOD1 genotyping and NOD2 variant confirmation were performed by specific amplification and sequencing. RESULTS： The distribution of NOD1 polymorphism in patients was different from controls （P = 0.045） and not altered by existence of NOD2 mutations. In this cohort, 30.92% patients and 6% controls carried at least one NOD2 variant （P 〈 0.001） with R702W being the most frequent variant. Presence of at least one NOD2 mutation was inversely associated with colon involvement （9.09% with colon vs 36.4% with ileal or ileocolonic involvement, P = 0.04） and indicative of risk of penetrating disease （52.63% with penetrating vs 25.64% with non-penetrating or stricturing behavior, P = 0.02）. L1007finsC and double NOD2 mutation conferred the highest risk for severity of disease （26.3% with penetrating disease vs 3.8% with non-penetrating or stricturing behavior presented L1007finsC, P = 0.01 and 21.0% with penetrating disease vs 2.5% with non-penentrating or stricturing behavior carried double NOD2 mutation, P = 0.007）. Exclusion of patients with NOD2 mutations from phenotype/NODl-genotype analysis revealed higher prevalence of ＊1＊1 genotype in groups of younger age at onset and colonic location.CONCLUSION： This study suggests population differences in the inheritance of risk NOD1 polymorphism and NOD2 mutations. Although no interaction between NOD1-NOD2 was noticed, a relationship between disease location and Nod-like receptor molecules was established.

Background: Measures to contain the COVID-19 transmission reached teaching routines of universities worldwide with possible mental health consequences for anxiety. This study assessed prevalence and risk factors for stress, depression, and anxiety (SDA) in medical students during quarantine by COVID-19. Methods: A cross-sectional observational study of medical students by means of the DASS-21 questionnaire. Risk factors for SDA were assessed based on epidemiologic questions related to COVID-19. Receiver Operating Characteristics (ROC) curves were calculated for each predictor, as well as sensitivity and specificity. Results: This survey reached 1009 responses. A prevalence of 77.5% for some SDA disorder was found, 63% being severe. Previous diagnosis of psychiatric disorder was a factor of risk for anxiety (OR 2.78 CI95% 1.44 - 14.25, p = 0.044), as well as for depression (OR 3.37 CI95% 1.98 - 6.02, p Conclusion: Psychiatric conditions as well as chronic illnesses were risk factors for high prevalence of anxiety, depression and stress during the COVID-19 pandemic among medical students.
