title: Hypertension as a risk factor for female sexual dysfunction: cross-sectional study

description: ABSTRACT Objective: to evaluate the sexual dysfunction in hypertensive patients compared to normotensive patients. Method: this was a cross-sectional study. Samples were composed of 54 hypertensive patients and 54 normotensive patients. The female sexual dysfunction was evaluated by the Female Sexual Function Index (FSFI). Results: the average FSFI score differed highly between hypertensive and normotensive patients (22.4± 7.4 versus 26.8 ±5.4, p&lt; 0.001). Among hypertensive patients, 63% showed sexual dysfunction in opposition to 39% of normotensive patients (p=0.02). Hypertensive women had 1.67 more chances of showing the dysfunction than women with normal blood pressure. Conclusion: the sexual dysfunction prevalence is higher in hypertensive than in normotensive women hence, hypertension is a potentiator factor for female sexual dysfunction.

title: SOFT SENSOR MODELS FOR A FRACTIONATION REFORMATE PLANT USING SMALL AND BOOTSTRAPPED DATA SETS

description: Abstract In refinery plants key process variables, like contents of process stream and various fuel properties, need to be continuously monitored using adequate on-line measuring devices. Such measuring devices are often unavailable or malfunction and, hence, laboratory assays which are irregular and time consuming and therefore not suitable for process control are inevitable alternatives. This research shows a comparison of different soft sensor models developed from a small industrial data set with soft sensor models developed from data generated by a bootstrap resampling method. Soft sensors were developed applying multiple linear regression, multivariable adaptive regression splines (MARSpline) and neural networks. The purpose of the developed soft sensors is the assessing of benzene content in light reformate of a fractionation reformate plant. The best results were obtained by the neural network-based model developed on bootstrapped data.

title: Description of the final instar larva of Argia serva Hagen in Selys, 1865 (Odonata Coenagrionidae)

description: Abstract The American genus Argia, with more than 100 species described, is the most speciose genus of Odonata in the world. In this contribution, the final stadium larva of Argia serva, the southernmost distributed species of Argia, is described and diagnosed based on reared material from Martín García island, Buenos Aires, Argentina. The larva of this species can be easily separated from the other Argentinean Argia by the following combination of characters: sternum of S8 covered with spines (bare in A. translata); antennal segment 3 longer than 1+2 (equal to or shorter than 1+2 in A. joergenseni and A. jujuya); palpal setae absent (present in A. croceipennis). A key to the known larvae of Argia of the Southern Cone is provided.

title: Process optimization, physicochemical characterization and antioxidant potential of novel wine from an underutilized fruit Carissa spinarum L. (Apocynaceae)

description: Abstract Carissa spinarum L., is a tropical underutilized fruit abundantly available during summer season, which is delicious to taste with an astringency flavor and fruity aroma. Hence, the present investigation was aimed at optimizing fermentation conditions for the production of wine and to assess its physiochemical composition and antioxidant activity. Response surface methodology coupled with central composite design was employed for the optimization studies. It was determined that fermentation temperature of 25°C, pH of 3.5 and inoculum size of 10% (v/v) resulted in quality wine with 8.3% (v/v) of ethanol content. Further, physicochemical composition and antioxidant activity of the optimized wine was found to be significantly higher or on par with other tropical fruit wines reported previously. Sensory analysis indicated that wine was good in terms of overall acceptability. Thus, availability of C. spinarum fruits during their glut season can be utilized for winemaking and could generate revenue among rural households further adding significant input to the economy of fruit wine market.

title: Nutritional and protein quality of dry Brazilian beans (Phaseolus vulgaris L.)

description: Abstract Brazil is the world's largest producer of common beans (Phaseolus vulgaris L.), which are one of the most widely consumed grain legumes in the world. Seven improved genotypes of dry, coloured, Brazilian common beans were analysed for their nutritional (chemical composition, oligosaccharides, phenolic compounds and antioxidant capacity) and protein quality (amino acid profile, amino acid score, trypsin inhibitor activity and in vitro protein digestibility). The grain bean cultivars studied showed a high content of fibre, with some aromatic amino acids present at higher levels than the Food and Agriculture Organization reference protein. The dry beans had intermediate protein digestibility, ranging from 50.3% in the BRS Notável cultivar to 66.9% in the Jalo Precoce cultivar. The studied dry beans contained anti-nutritional and flatulence factors, such as trypsin inhibitors and oligosaccharides. However, total phenolic compounds and antioxidant activity were high. Improved grain beans have important nutritional characteristics that need to be preserved, and some negative, anti-nutritional characteristics. The results presented in this study can be used to assist the identification of appropriate processing techniques that maintain the positive features of dry beans and eliminate their negative attributes.

title: The Belterra Clay on the bauxite deposits of Rondon do Pará, Eastern Amazon

description: ABSTRACT: Bauxite deposits in the Amazon region are commonly covered by yellowish clays which can reach up to 25m thick, known as Belterra Clay (BTC). In Rondon do Pará, Eastern Amazon, BTC is 13m thick and covers world-class bauxite reserves. Three pilot bauxite mines were investigated in Rondon do Pará for an initial characterization of the local BTC. In discordant contact with the lateritic profile, the BTC has reddish brown colors at its base to ocher tones towards the top. It has a massive structure with silt-clayey texture and nodular bauxitic fragments at its base. Rietveld mineral quantification of the material attests that it is dominated by kaolinite, with goethite, gibbsite, hematite, anatase and residual quartz. The thermal behavior of the material also confirms its mineralogical composition. Kaolinite is of low structural order, which was considered the main difficulty in the application of the Rietveld method. Goethite has up to 33 mol% of Al. As observed by scanning electron microscopy (SEM), the minerals represent pseudo-hexagonal crystals measuring from 150 to 700 nm. The BTC in the studied area is correlated to BTC on others bauxitic deposits of the Amazon region, suggesting this material experienced the same genesis and geological evolution, probably during the Pliocene.

title: Objective and subjective prior distributions for the Gompertz distribution

description: Abstract This paper takes into account the estimation for the unknown parameters of the Gompertz distribution from the frequentist and Bayesian view points by using both objective and subjective prior distributions. We first derive non-informative priors using formal rules, such as Jefreys prior and maximal data information prior (MDIP), based on Fisher information and entropy, respectively. We also propose a prior distribution that incorporate the expert’s knowledge about the issue under study. In this regard, we assume two independent gamma distributions for the parameters of the Gompertz distribution and it is employed for an elicitation process based on the predictive prior distribution by using Laplace approximation for integrals. We suppose that an expert can summarize his/her knowledge about the reliability of an item through statements of percentiles. We also present a set of priors proposed by Singpurwala assuming a truncated normal prior distribution for the median of distribution and a gamma prior for the scale parameter. Next, we investigate the effects of these priors in the posterior estimates of the parameters of the Gompertz distribution. The Bayes estimates are computed using Markov Chain Monte Carlo (MCMC) algorithm. An extensive numerical simulation is carried out to evaluate the performance of the maximum likelihood estimates and Bayes estimates based on bias, mean-squared error and coverage probabilities. Finally, a real data set have been analyzed for illustrative purposes.

title: PRODUCTION OF CASTOR OIL MALEATE USING DI-TERT-BUTYL PEROXIDE AS FREE RADICAL CATALYST

description: Abstract Castor oil maleate is used in healthcare products, synthetic lubricants, drying oils, water-soluble paints and as a monomer in several polymers. This compound is formed by direct reaction between castor oil and maleic anhydride, which can be accelerated using free radical catalysts. In this work, the influence of processing temperature and the concentration of di-tert-butyl peroxide (DTBP) in the production of castor oil maleate was studied applying response surface methodology. The results showed that the use of the radical initiator increased the rate of reaction, leading to a shorter reaction time and higher productivity. The optimal operating condition was found at 120ºC, 1 mol of maleic anhydride/mol of castor oil and 0.005 mol of DTBP/mol of castor oil, yielding 90.2% of castor oil maleate in 90 min.

title: Electrocardiogram in Chagas disease

description: Abstract Since the initial descriptions of Chagas cardiomyopathy (ChCM), the electrocardiography has played a key role in patient evaluations. The diagnostic criterion of chronic ChCM is the presence of characteristic electrocardiographic (ECG) abnormalities in seropositive individuals, regardless of the presence of symptoms. However, these ECG abnormalities are rarely specific to ChCM and, particularly among the elderly, can be caused by other simultaneous cardiomyopathies. ECG abnormalities can predict the occurrence of heart failure, stroke, and even death. Nevertheless, most prognostic studies have included Chagas disease (ChD) populations and, not exclusively, ChCM. Thus, more studies are required to evaluate the efficacy of ECG in predicting reliable prognoses in established chronic ChCM. This review exclusively discusses the role of the 12-lead ECG in the clinical evaluation of chronic ChD.

title: Secondary Education reform in the Temer administration: corrosion of the right to education in the context of a financial crisis in Brazil

description: ABSTRACT This paper analyzes the secondary education reform initiated with the provisional measure n. 746/2016 and its relation with the financial crisis. Other than pointing out contradictions between law n. 13.415/2017 and other education laws, a counterpoint was made between the first reactions of the progressive field of education and the arguments representing neoconservative and neoliberal elites that took the power through the political-media-aided-juridical coup in August 2016. The flexibility and the hollowing out of the secondary school curriculum can result in the corrosion of the right to education. Restrictive measures of primary expenses by the State (DRU, PEC 241/55 and both welfare and labor reforms) aim to stifle the state’s “expenditures” on welfare in order to deepen fiscal adjustment and guarantee better accumulation conditions by rentier sectors of the capital.
