title: RAINFALL CHARACTERIZATION AND SEDIMENTOLOGICAL RESPONSES OF WATERSHEDS WITH DIFFERENT LAND USES TO PRECIPITATION IN THE SEMIARID REGION OF BRAZIL

description: ABSTRACT The objective of this work was to evaluated the precipitation characteristics (depth, I30 and erosivity) and their effects on sediment production in three watersheds under different managements of land use 35-year regenerating Caatinga (RC), thinned Caatinga (TC), which underwent thinning of trees with diameter smaller than 10 cm; and deforested Caatinga (followed by burning and pasture) (DC). The experimente was conducted in the central, tropical semiarid region of the State of Ceará, Brazil. The precipitation events, surface runoff and sediment production were monitored from 2010 to 2015. The precipitation characteristics were subjected to Pearson's correlation at 1 and 5% of significance and the events that produced sediments in each watershed were hierarchically grouped by hierarchical cluster analysis technique. Two hundred precipitation events were recorded, with 23 (RC), 18 (TC) and 43 (DC) events producing sediments. The use of thinning (TC) decreased the sediment production by 53.5%, while the deforestation, burn and pasture cultivation (DC) increased soil losses by 14%, compared with the RC. The sediment production was greatly correlated with the I30 in the three watersheds, denoting the erosion process great dependence on the precipitation intensity.

title: Soil Physical and Chemical Properties in Epigeal Termite Mounds in Pastures

description: ABSTRACT We characterized soil physical and chemical properties and soil organic matter in epigeal termite mounds in pastures to evaluate the changes promoted by termites in comparison to an adjacent area. We selected seven active epigeal termite mounds in the municipality of Seropédica, state of Rio de Janeiro, Brazil. Soil samples were collected from top, center and base positions of each mound, at 0.50 and 1.50 m distance from the base of the mound. We identified individuals of the genus Embiratermes, Velocitermes, and Orthognathotermes. The humin fraction predominated over the humic and fulvic acid fractions both in mounds and adjacent soil. The amount of organic matter and the mineral fractions (mineral-associated organic carbon - MOC) varied among builder species. The studied chemical attributes point to a higher concentration of nutrients in the mounds than in the adjacent soil.

title: Quantifying dilution caused by execution efficiency

description: Abstract In open pit mining, dilution is not always a factor systematically analyzed and calculated. Often it is only an adjusted number, for example, calculated or even empirically determined for a certain operational condition perpetuating along time in the form of a constant applied to calculating reserves or mine planning in attendance of audit requirements. Dilution and loss are factors that should be always considered for tonnage and grade estimates. These factors are always associated and can be determined considering several particularities of the deposit and the operation itself. In this study, a methodology was determined to identify blocks adjacent to the blocks previously planned to be mined. Thus, it is possible to estimate the dilution caused by poor operating efficiency, taking into account the inability of the equipment to perfectly remove each block, respecting its limits. Mining dilution is defined as the incorporation of waste material to ore due to the operational incapacity to efficiently separate the materials during the mining process, considering the physical processes, and the operating and geometric configurations of the mining with the equipment available.

title: Factors associated with morphometric brain changes in cognitively normal aging

description: OBJECTIVE: Cognitive impairment is associated with reductions in brain weight and volume. The factors related to morphometric brain changes in cognitively normal aging remain unknown. We aimed to identify which clinical factors are associated with morphometric brain changes in cognitively normal aging. METHODS: A cross-sectional study of 414 subjects, ≥50 years old submitted to clinical assessment and brain autopsy, after informed consent, was carried out at the São Paulo Autopsy Service, Brazil. Data on cognitive and functional evaluations were collected through structured interview applied to the next-of-kin. Brain weight (g) and volume (mL) measurements were obtained and adjusted for head circumference (cm). Associations between brain weight/volume and related factors were obtained through univariate and multivariate analysis. RESULTS: Participants were predominantly male (60.4%), Caucasian (69%), with mean age of 67.1 ± 10.9 years. Mean brain weight was 1219.2 ± 140.9 g, and mean brain volume was 1217.1 ± 152.3 mL. Head circumference was independently associated with low brain weight (p&lt;0.001) and volume (p&lt;0.001). Total and adjusted brain weight and volume decreased in some conditions. Female gender (p&lt;0.001), hypertension (p&lt;0.009), coronary artery disease (p&lt;0.013) and walking assistance (p&lt;0.011) were associated with lower adjusted brain weight while schooling was associated with higher adjusted brain weight (p&lt;0.003). Female gender (p&lt;0.001), age (p&lt;0.001) and hypertension (p&lt;0.011) were associated with low adjusted brain volume. CONCLUSION: Morphometric brain changes occur despite the absence of cognitive impairment and were predominantly associated with age, female gender, mobility impairment and cardiovascular conditions. Schooling may be a protective factor.

title: Reinforced Transparencies for Aerospace Application – Case Description

description: ABSTRACT This paper describes the polycarbonate acrylic laminated development that can be applied in aeronautics and aerospace transparencies. The case studied is a laminated double-curved transparency (bubble form) used in an observation side window of a military aircraft. Side windows need strength and specific characteristics, similar to windshields, allowing the perfect visualization and image capture. Laminated transparencies composed by different materials have better qualities than the monolithic ones. This kind of transparency can offer high mechanical and chemical resistance, high transparency, no fragmentation and easy maintenance or recovery. A significant amount of information about materials and processes was jointed in order to build the reinforced transparency and validate this study. The final results were analyzed based on two points of view: mechanic resistance and, especially, optical quality.

title: The American Dream and the culture of appearances in Mervyn LeRoy’s Little Caesar

description: Abstract Known as the precursor of the gangster sound films from this genre’s “classic” period, Little Caesar, directed by Mervyn LeRoy in 1931, narrates Rico Bandello’s (Edward G. Robinson) path from his rise as a gang leader to his death. Little Caesar established the parameters followed by the gangster films in the 1930s and also contributed to the image of the gangster as an American icon due to its dissemination through the cultural industry, mainly in terms of films. My objective with this present article is to verify through the analysis of some of the scenes how the culture of appearances and the ideology of the American Dream are configured throughout the narrative.

title: The Physical Activity Level, Body Composition and Diabetes Mellitus Influence the Association Between Depression and Hypertension in Community-Dwelling Elders

description: Abstract Background: Depression and hypertension are highly prevalent among elderly people. Although the relationship between these conditions is well recognized, however, the factors that may influence such association are not clearly understood. Objective: To analyze the association between depression and hypertension in community-dwelling elders. Methods: Two-hundred and thirty-one community-dwelling elders provided information regarding the following variables: sex, age, ethnicity, smoking habit, physical activity level (PA), body mass index (BMI) and diabetes mellitus (DM). These variables can potentially influence depression and hypertension, as well as its relationship. Screening for depression was made using the Geriatric Depression Scale (GDS). The presence of hypertension was defined based on self-reported data and/or the use of antihypertensive drugs. The logistic regression technique was applied, using hypertension as the dependent variable and depressive state as a predictive variable. Logistic regression was applied with and without adjustment for the potential intervening variables. Results: The prevalence of depressive state and hypertension in the studied population was 14% and 59%, respectively. The association between depression and hypertension without adjustments was not significant (odds ratio [OR] = 2.28, 95% confidence interval [95%CI] = 0.98 - 5.32; p = 0.06). However, after adjusting for PA, BMI and DM, the strength of association between depression and hypertension significantly increased (OR = 3.08, 95%CI = 1.12 - 8.46; p = 0.03). Conclusion: The association between depression and hypertension in the elderly is directly influenced by PA, BMI and DM. This finding may guide strategies to increase the adherence to a healthier lifestyle.

title: Association of Fusarium and Phomopsis with Peroba Rosa Seeds

description: ABSTRACT Peroba rosa (Aspidosperma polyneuron) is a native forest species endangered due to intense predatory exploitation. The objective of this study was to evaluate the association and fungi transmission in peroba rosa seeds from four regions of Paraná. Germination and vigor were evaluated using the paper roll method. Sanitary analysis consisted of the detection of endophytic and epiphytic fungi using potato-dextrose-agar medium and Fusarium selective medium. For transmission, non-disinfested seeds were sown in vermiculite and kept in greenhouse. Germination ranged from 9.3% to 60%. Fusarium sp. and Phomopsis sp. were found as epiphytic and also as endophytic. There was transmission of Fusarium sp. and Phomopsis sp. from seeds to seedlings, causing malformation and necrosis on roots and cotyledons.

title: Carotid Atherosclerosis in Pre- and Post-Menopausal Women with a History of Pregnancy-Induced Hypertension: Case-Control Study

description: Abstract Background: Cardiovascular disease mortality among women remains high. Observational studies are controversial about the participation of a history of gestational hypertensive disorder in cardiovascular risk. Objective: To verify the association between carotid atherosclerosis in menopausal women who had pregnancy-induced hypertension. Methods: Case-control study, with cases consisting of women with carotid atherosclerosis, defined as carotid intima-media thickness &gt; 1 mm and/or presence of carotid plaques; the controls did not have these alterations. The significance level was set at 95%. Results: A total of 504 women without previous cardiovascular disease were assessed, 126 cases and 378 controls. Of the total, 67% were hypertensive; 76% were dyslipidemic; and 16% were diabetic. Approximately 10% reported a history of hypertension during pregnancy. Women with carotid atherosclerosis had higher values of systolic blood pressure (134.18 mmHg vs. 128.59 mmHg, p = 0.008) and LDL-cholesterol (156.52 mg% vs. 139.97 mg%; p = 0.0005). No statistical difference was found regarding the presence of carotid atherosclerosis and history of hypertension during pregnancy (OR 1.672, 95% CI: 0.883-3.131). Conclusion: The history of hypertension during pregnancy was not associated with subclinical carotid atherosclerosis in menopausal women. However, an association was observed between carotid atherosclerosis and classic risk factors, such as elevated systolic blood pressure and LDL-cholesterol levels.
