title: Taxonomic Distinctness of the subterranean fauna from Peruaçu Caves National Park, state of Minas Gerais, eastern Brazil

description: Abstract: Limiting factors of subterranean environments, high relative air humidity and, especially, permanent darkness, represent ecological filters for organisms and biodiversity patterns of surface and subterranean communities display wide disparities. Subterranean diversity and singularity are, thus, better expressed when the common presence of rare and endemic species are considered. Our study aimed to describe the diversity of the cave fauna from 14 caves from Peruaçu Caves National Park (PCNP), eastern Brazil. We analyzed the regional diversity using the index that includes the average taxonomic distinction (TD - Δ +, AvTD). We recorded 1,674 individuals belonging to 10 Classes and 237 morphotypes, 11 troglobitic and two troglomorphic and possible troglobites. Greatest species abundance (N=330) and richness (s=76) were recorded at Lapa do Cipó cave, followed by Gruta Olhos d’Água (N=330, s=71), which shows the highest TD value (Δ + = 90.18) in relation to the others, including the richest Lapa do Cipó (Δ + = 85.24), consequence of the several taxonomic units with large number of species. The below-expected values of TD (Δ + = 87.70) may indicate anthropic impacts on these communities. Our results demonstrate that Gruta Olhos d’ Água and Lapa do Cipó caves are the most important sites for the occurrence of endemic and troglobitic species and may be part of a complex system that should be considered for a more efficient conservation planning.

title: Ideal harvesting point of ‘Limeira-IAC382’ trifoliate orange fruits for seed extraction

description: Abstract Trifoliate orange is one of the rootstocks most used worldwide mainly because it provides excellent quality fruit production. Harvest at the correct time is among factors that determine the physiological quality of seeds. The aim of this study was to identify physicochemical changes in ‘Limeira-IAC382’ trifoliate orange fruits, searching for the ideal harvest moment to obtain high quality seeds. Fruits were harvested at 180, 210 and 240 days after anthesis, stored in cold chamber and evaluated at 0, 15, 30 and 45 days of storage. The following variables were determined: mass loss, fruit color index, soluble solids, total titratable acidity and fruit juice ratio. Seeds were manually extracted and dried until reaching 30% water content. Seeds were used for the performance of germination, electrical conductivity and greenhouse seedling emergence tests. Seeds from fruits harvested at 240 DAA showed higher germination and greenhouse seedling emergence percentage compared to the other treatments until 30 and 45 days of storage in cold chamber, respectively. Storage for 45 days in cold chamber of fruits harvested at 210 DAA increases seed germination rate and the percentage of seedlings from seeds harvested at 180 DAA. It could be concluded that the harvesting of ‘Limeira-IAC382’ trifoliate orange fruits should be performed when fruits reached yellowish peel and low juice ratio, aiming at obtaining seeds with physiological quality.

title: In-row spacing and shoot thinning for ‘Chardonnay’ grapevines in the south of Minas Gerais, Brazil

description: ABSTRACT: The quality of sparkling wine reflects the climate and management of vineyard, since these factors affect grape development, berry composition, and base wine composition. ‘Chardonnay’ vines were subjected to five in-row spacing distances (0.5; 0.75; 1.0; 1.50; and 2.0 m) combined with and without shoot thinning. For each in-row spacing, vines were thinned to 5, 8, 10, 15, and 20 shoots per plant. Vegetative growth, yield, berry composition and base wine composition were analyzed for two years. Vines with decreased in-row spacing, presented fewer clusters and malic acid content in berries, mostly related to the shading effect. Shoot thinning increased bud fruitfulness and decreased leaf area per meter, leaf area per plant, and leaf layer number. In-row spacing from 1.5 m to 0.5 m showed promising results for the Southeast Brazil with higher yield per hectare and sufficient acidity to provide freshness in sparkling wines.

title: Modeling of H2S Dispersion in Brazil with Aermod: Case Study of Water Resource Recovery Facility In South of Brazil

description: Abstract Water Resource Recovery Facility (WRRF) can be source of odorous gases. We analyzed the emission and dispersion of hydrogen sulfide gas (H2S), odor indicator, produced during the anaerobic treatment of wastewaters, using WATER9 and AERMOD models for two distinct events: August 2013 and February-March 2014. Data from two WRRF in Brazil were used to feed the model and a statistical data validation was performed, followed by an evaluation of model results regarding H2S emission and dispersion. Daily peak events and averages over the two periods were calculated. Results show a good performance from the model in comparison to the observations. Moreover, odor plumes typically reached 2-4 km from their sources and they may be strongly affected by atmospheric stability/instability conditions in the events analyzed and, in general, only the residences at the vicinity of WRRF were affected by the pollutant odor. Finally, the methodology presented showed to be feasible and realistic for purposes of WRRF planning and management.

title: Seroprevalence of cytomegalovirus and its coinfection with Epstein-Barr virus in adult residents from Manaus: a population-based study

description: Abstract INTRODUCTION: This study assessed the seroprevalence of cytomegalovirus, associated factors, and Epstein-Barr virus coinfection among adult residents of Manaus. METHODS: Using a cross-sectional study design, we collected blood samples from 136 individuals in a household survey in 2016. Prevalence ratios were calculated using Poisson regression. RESULTS: Cytomegalovirus and Epstein-Barr virus seroprevalences were 67.6% (95% CI: 9.7-75.6%) and 97.8% (95% CI: 95.3-100.0%), respectively. Coinfection was observed in 66.2% (95% CI: 58.1-74.2%) of participants. Bivariate analysis showed no statistical association. CONCLUSIONS: Seroprevalences were high among participants and approximately 7 out of 10 individuals had cytomegalovirus and Epstein-Barr virus coinfection.

title: Indigenous Amazonia: the forest as a subject

description: Abstract Managed and cultivated by humans for millennia, the Amazon rainforest was altered, but (as the subject of its own renovation) is still a forest. In other words, Amazonia became ‘anthropogenic’ – both cultural and natural, the result ofa two-way relationship between subjects: Man and the Forest, with the activities of one not nullifying those of the other. Thanks to anthropology, we know that the indigenous societies of Amazonia confer the dignity of a person or subjecton non-humans. The relationship between subjects (symmetrical, dialogic, reciprocal) is an ethical as well as poetical relationship. On the other hand, what prevails in western civilization is the subject-object relationship (asymmetrical, authoritarian, dominating), which generates Nature as an object, opposed to Man as a subject, the sole bearer of Culture. Meanwhile, “the other as an object” means denying the other and denying ethics. This is the substance ofthe radical alterity of indigenous ways of being and thinking with regard to the West; this “indigenous alterity” for us is a treasure of wisdom. Yet there is a childlike, poetic West that recognizes itself in the indigenous people and in their experience of the world.

title: Do as I Do, Not as I Say: Incentivization and the Relationship Between Cognitive Ability and Risk Aversion

description: Abstract We study the relationship between cognitive ability and risk aversion under real and hypothetical choice conditions. Our experimental results suggest that the statistical relationship between cognitive ability and risk aversion is sensitive to incentive conditions of the choice problems used to elicit risk preferences. Individuals in the upper tail of the cognitive ability distribution are willing to take more risks. However, this holds only when choices involve hypothetical payoffs. When choices envolve monetary incentives, this correlation is not significant. Results are robust to using alternative measures of cognitive ability.

title: Influence of Meteorology on Fine Particles Concentration in Vitória Metropolitan Region During Wintertime

description: Abstract Fine particles (PM2.5) are harmful to human health especially during periods of limited dispersion when the concentrations build up. This is a common occurrence in Southern Brazil in the dry season when high-pressure stationary systems inhibit vertical dispersion and reduce wind speed. The objective of this study was to evaluate the PM2.5 concentrations in the Region of Greater Vitória during the winter of 2013, and to assess the influence of the large-scale meteorological circulation on its concentration. An experimental campaign was carried out to determine the mass of PM2.5 at six urban sites and particle number concentration. The average PM2.5 concentrations varied from 9.70 μg m-3 to 14.36 μg m-3 with the average daily maximum reaching 29.35 μg m-3, exceeding the World Health Organization guideline (24-h average: 25 μg m-3). The particle size distribution showed a larger number of particles from 18 to 21 h (local time), indicating that the main vehicular emissions are the main sources. During the winter, rainfall associated with cold fronts were responsible for a decrease in the particulate concentrations. In contrast, the occurrence of high-pressure systems led to an increase in particle concentrations, due to stagnant conditions.

title: Mechanical and Microstructural Characterization of AS-CAST Ti-12Mo-xNb Alloys for Orthopedic Application

description: The development of β-metastable titanium alloys that combine low Young’s modulus, good mechanical properties, corrosion resistance and biocompatibility has attracted industry interest. This type of alloy is an alternative to commercial alloys such as Ti-6Al-4V, avoiding the cytotoxic effect that occurs with Al and V in the human body in the manufactured orthopedic prostheses. In this scenario, the present work aims to characterize the effect of Nb concentration in the properties of Ti alloys based on the Ti-12Mo-xNb stoichiometry (x = 0, 3, 8, 13, 17 and 20). All alloys were produced by arc melting with non-consumable tungsten electrode in an argon atmosphere and the ingots were characterized by x-ray diffraction (XRD), optical microscopy (OM), Vickers microhardness and Young’s modulus was measured by impulse excitation and density was measured using the Archimedes’ principle. The Ti-12Mo alloy and the Ti-12Mo-20Nb alloy showed the lowest Young’s modulus. The best hardness/modulus was found for the Ti-12Mo-3Nb alloy. All the alloys studied in this work showed hardness/modulus ratio above the traditional Ti-6Al- 4V alloy (2.85), presented great potential for the biomedical application.
