title: SQUAMOUS CELL CARCINOMA IN OVINES IN THE STATE OF ACRE

description: ABSTRACT: The squamous cells carcinoma (SCC), also known as epidermoid carcinoma, is a malign neoplasia of the squamous layer of the skin's epidermis, very common in bovines of tropical countries such as Brazil, due to the chronic exposure of animals to ultraviolet radiation. The objective of this work was to describe SCC cases in sheep (Ovis aries ), because it is known that this disease is rare in this species. A standard animal of approximately six years old was assisted in the municipality of Rio Branco, State of Acre, in Brazil, presenting cachectic state and multifocal tumors. Despite the rarity of this neoplasia in sheep, it is important to use preventive measures, such as: avoiding acquisition of depigmented animals, with absent or sparse fur coverage and, mainly avoiding prolonged exposure to ultraviolet lights, which could cause the appearance of this morbid disease.

title: Cationic flotation of smithsonite and dolomite from Brazilian Ambrósia Norte Deposit

description: Abstract The flotation of low-grade oxidized zinc ores has been commonly used to produce marketable concentrates for many years. Several flotation routes are being successfully used: cationic, anionic and a mixture of anionic and cationic. The choice of the route taken is dependent on the major zinc-bearing minerals in the deposit of interest and its associated gangue. Since both the mineralogical composition of zinc ores and the chemical composition of smithsonite and dolomite vary between deposits, the physico-chemical conditions under which selective flotation processes are determined must be established for each unique case. In this study, cationic flotation tests were performed using smithsonite and dolomite samples from an unstudied oxidized zinc deposit in Brazil, using Na2S as the sulfidizing agent, sodium silicate as the depressant and amine as the collector. The surface charges of both minerals were investigated with and without reagents. These tests showed that the optimum conditions of flotation were reached at pH 11. Na2S allowed a significant increase in the recovery of smithsonite, which implies lower amine consumption. Sodium silicate functioned as a dolomite depressant at concentrations up to 6.0 mg/L. The results for both flotation and the zeta potential of the minerals were analyzed using specimen diagrams of the reagents and compared with studies published in previous literature.

title: Epidemiological and spatial analysis of cases of gestational and congenital syphilis

description: ABSTRACT The aim of the present study was to analyze the epidemiological profile and spatial distribution of gestational and congenital syphilis cases. This is a descriptive, exploratory and retrospective research, with a quantitative approach, conducted in Caxias (MA). Data from case reports confirmed by gestational and congenital syphilis of the Notification Recording Information System from 2013 to December 2017 were used. With the Global Positioning System technology, case coordinates were collected, and with the Quantum GIS program, version 1.7.0, the maps were built. There were 149 cases of gestational syphilis, presenting a growth of 73% in the period. The highest prevalence occurred in young, brown women with low schooling and housewives. Higher frequency of diagnosis in the third gestational trimester was evidenced, with higher prevalence of primary syphilis. There were 18 cases of congenital syphilis, with a 33% reduction in detection rate and age prevalence between 1 and 28 days of life. In the spatial analysis, the West and East zones, outskirts of the municipality, concentrated the largest number of cases. It reveals the fragility in the research management, making it detrimental to permanent education, to qualify the professionals, in order to institute early identification, timely treatment and effective follow-up.

title: Formation of monazite-(Ce, La) by fluid-apatite interaction: the Floresta Azul Alkaline Complex, Bahia, Brazil

description: ABSTRACT: Monazite is a common accessory mineral in the Floresta Azul Alkaline Complex, occurring in three different rock types, which form this batholith: nepheline syenite, granite and fenite. Two compositional types of monazite can be found: monazite-(Ce) and monazite-(La), the latter being found only in syenites. Monazite occurs in close association with apatite as anhedral crystals ranging in size from 0.1-100 µm, and textures indicate different genetic processes. In nepheline syenite, monazite is closely related to ancylite and apatite, as a late crystallizing phase. Monazite occurs in granites as pore fillings in apatite and was formed by the remobilization of rare earth elements (REE) from apatite by late CO 2 - rich fluids. In fenite, monazite appears as acicular crystals, parallel to apatite’s crystallographic c-axis formed by exsolution from apatite by metamorphism. The data show that the monazite genesis was closely related to the activity of fluids associated either with the final stages of crystallization of nepheline syenite and granite or with fenitization of country rock.

title: CARBON SOURCES AND C:N RATIOS ON WATER QUALITY FOR NILE TILAPIA FARMING IN BIOFLOC SYSTEM

description: ABSTRACT The use of biofloc technology (BFT) can improve fish production in regions with low water availability. Therefore, information on dynamics of water quality is essential for success in fish rearing. Thus, the objective of the present study was to evaluate the water quality for Nile tilapia farming in a system without water exchange, during the fingerling stage, using different sources of carbon and C:N ratios. A completely randomized experimental design was used in a 2x3 factorial arrangement, with two carbon (C) to nitrogen (N) ratios (10:1 and 20:1) and three carbon sources (sugar, molasses and cassava starch). The C:N ratio and carbon source affected the variables alkalinity, settleable solids (SS), turbidity and total suspended solids (TSS), showing significantly higher values at C:N ratio of 20:1 (P &lt; 0.05). The best carbon source for microbial floc formation were the molasses and sugar, under C:N ratios of 10:1 and 20:1. The stability of the monitored water quality parameters occurred from 6 to 7 weeks of rearing. The growth performance of Nile tilapia in BFT system fertilized with different organic carbon sources was not significantly different (P &lt; 0.05) between treatments. The use of molasses to fertilize BFT systems can reduce costs of production in regions where this product is available.

title: INSECT DIVERSITY IN AN EXPERIMENTAL VINEYARD IN THE STATE OF RIO GRANDE DO NORTE, BRAZIL

description: ABSTRACT: The objective of this work was to survey the entomofauna in an experimental vineyard (Vitis spp.) in the semiarid of the State of Rio Grande do Norte (RN), Brazil. The survey was conducted from November 2012 to January 2013 at the Rafael Fernandes experimental farm of the Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró, RN, in an area of 2,500 m2, cultivated with the Italia, Niagara Rosada and Isabel grapevine varieties. The insect collection was performed weekly during the grapevine flowering and fruiting periods, through a passive method, using four Pitfall traps, and an active method, collecting insects from the tree canopies (branches, leaves, flowers and fruits) using entomological net, tweezers and brushes. In the passive collection, 1,598 insects from five orders and 25 families were collected, especially from the Formicidae (83%), Dolichopodidae (5.9%) and Cicadellidae (1.9%) families, which were the most abundant. In the active collection, 288 insects from five orders and 14 families were collected, especially from the Vespidae (160 specimens) and Apidae (78 specimens) families, which were the most abundant, representing 82.7% of the total collected insects. The greater diversity (13 families) and greater number of insects collected (186 specimens) were observed in the grapevine variety Isabel.

title: Quality of life of Brazilian immigrant women living in Portugal

description: ABSTRACT This article aims to evaluates the Quality of Life (QoL) of Brazilian women living in Portugal. The 'Medical Outcomes Study: 36-Item Short Form Survey' (SF-36) and a sociodemographic questionnaire were applied to the sample of 682 Brazilian women over 18 years old. The average values for the predictors of QoL were higher for the dimension 'functional capacity'; whereas 'emotional aspects', 'mental health', and 'vitality' showed lower values. It was found that the processes of migration and QoL constitute an agenda of continuous research for health promotion in the hosting country.

title: Comparative Assessment of stabilised Polybutadiene Binder under Accelerated Ageing

description: ABSTRACT Polybutadiene elastomers are versatile materials, being employed at several applications from rocket propellant binder to adhesives and sealants. The elastomers derived from hydroxyl-terminated polybutadiene are usually stabilised with antioxidants to prevent degradation. In this study, a comparative assessment among 2,2’-methylene-bis (4-methyl-6-tert-butylphenol) (AO2246), 2,6-di-tert-butyl-4-methylphenol (BHT), p-phenylenediamine (pPDA), and triphenylphosphine (TPP) regarding stabilisation of hydroxyl-terminated polybutadiene binder under accelerated ageing (six months at 65 °C) was carried out. Evaluation of antioxidants effectiveness was examined through Oxidation Induction Time, sol/gel extraction, swelling and mechanical testing, dynamic mechanical analysis, and mass variation measurement. AO2246 yielded the best performance, meanwhile BHT was poorly protective. TPP acted as prooxidant, causing a severe degradation of the binder, and pPDA was not manageable to be assessed due to the lower curing degree of the resulted polyurethane.

title: Epidemiological study of metabolic syndrome in Brazilian soldiers

description: ABSTRACT Objective: The aim of this study was to carry out an epidemiological analysis of metabolic syndrome among Brazilian Army soldiers. Subjects and methods: Two thousand seven hundred and nineteen male soldiers of the Brazilian Army were evaluated from 2014 to 2016. Characteristics: age = 27.77 (± 8.59) years and BMI = 25.15 (± 3.41) kg/m2. Blood tests and anthropometric measures were performed following the criteria of the International Diabetes Federation Task Force on MS Epidemiology and Prevention, 2009. The epidemiological analysis was based on Odds ratio (OR) with confidence interval (CI). Results: The prevalence of MS found was 12.21%. Both WC and BMI proved to be good predictors of changes in MS physiological markers. Increased WC and BMI were strongly associated with all physiological markers. Soldiers with WC ≥ 90 were more likely to present MS with OR = 33.37 (24.37-45.7). Soldiers with WC ≥ 90 also presented high risk of: high triglycerides with OR = 5.98 (4.69-7.61); low HLD-c with OR = 1.78 (1.47-2.16); and increased systolic blood pressure OR = 3.10 (2.55-3.76). Soldiers with BMI ≥ 30 had a high risk of: increased glucose with OR = 2.69 (1.93-3.75); and increased diastolic blood pressure with OR = 3.02 (2.22-4.10). Conclusion: Both WC and BMI can be considered as good predictors of changes in MS physiological markers. We believe that WC and BMI should be used as screening tools to indicate the soldiers that must undergo blood tests to monitor MS prevalence.
