title: The Great Acceleration and Hydroelectric Dam Building in Brazil

description: Abstract In current debates about the planet's environmental future, the issue of energy uses is central, and its spatial distribution and speed of development will determine the evolution of climate change. Brazil is one of the countries that build the most dams in the world and the second greatest generator of hydroelectric power, after China. Generation of electric power from rivers has been privileged in the country since the government of Getúlio Vargas. Henceforth, the Brazilian federal state systematically promoted the development of hydroelectricity. In line with the global context, the construction of hydroelectric power stations in Brazil grew from the late 1950s onwards, especially after the military regime. This article proposes a reflection on the Brazilian electrification process from the point of view of hydroelectricity, from the introduction of this technology to the end of the military regime, adopting a multiplicity of scales. In this sense, the research seeks to clarify the factors that favored and those that restrained the hydroelectric expansion in twentieth-century Brazil and to contextualize the "great acceleration" of dam construction in the country.

title: Gastrointestinal parasites among felids inhabiting the Serra dos Órgãos National Park, Rio de Janeiro, Brazil

description: Abstract This study aimed to investigate the species of felids that inhabit the Serra dos Órgãos National Park (Parnaso) and gastrointestinal parasites at various stages of their life cycles in the feces of these animals. Between 2013 and 2015, felid feces were collected from trails in Parnaso. The sampling points were georeferenced. A total of 82 fecal samples were processed, of which 79 were collected on the ground, two from captured felids and one from a necropsied animal. All samples underwent coproparasitological techniques. Samples collected from the environment underwent additional trichological analysis. Fur patterns corresponding to Leopardus guttulus, Leopardus pardalis, Leopardus wiedii and Puma yagouaroundi were observed in 32 of the samples collected on the soil. High frequency of potentially parasitic evolving forms (88.6%) was observed in felid feces, particularly eggs of the family Diphyllobothriidae (68.6%). Besides, were also detected, eggs of superfamily Ascaridoidea (42.9%), nematode larvae (28.6%), eggs of order Strongylida (28.6%), Capillaria sp. (8.6%), Trichuris sp. (8.6%), eggs of order Spirurida (2.9%), unsporulated coccidian oocysts (8.6%) and Eimeria sp. (2.9%). Felid feces presented higher frequency of polyparasitism (60%) than monoparasitism (28.6%).

title: Sheep polyclonal antibody to map Haemonchus contortus mimotopes using phage display library

description: Abstract The aim of this study was to evaluate phage display technology for mapping Haemonchus contortus mimotopes. We screened the PhD-7 Phage Display Peptide Library Kit with a sheep polyclonal antibody against H. contortus. After four rounds of selection, 50 phage peptide clones were selected by biopanning and sequenced. Two clones displaying peptide mimotopes of H. contortus proteins were chosen for sheep immunization: clone 6 - mimotope of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and clone 17 - mimotope of a disorganized muscle family member (Dim 1). Twelve sheep were allocated into 3 groups of 4 animals as follow: G1: control group; G2/GAPDH: immunized with clone 6; and G3/Dim1: immunized with clone 17. Four immunizations were performed at intervals of seven days (0, 7, 14, and 21 days). On day 28 post initial vaccination, all groups were orally challenged with 2500 H. contortus infective larvae. The mimotope peptides selected by phage display were recognized by IgG from sheep naturaly infected with H. contortus. The immunization protocol showed an increasein IgG anti-M13 phage titers, but no effect was observed in IgG-specific for the anti-mimotope peptides. This is the first report of successful use of a phage display library for the identification of mimotopes of H. contortus proteins.

title: Notes on systemic functional linguistics, context of situation and transitivity with examples from children’s picture books

description: ABSTRACT Systemic functional Linguistics has contributed to studies in Applied Linguistics and other related areas of study. Thus, in this paper I first present an overview of SFL, the context of situation and the metafunctions, and then I move to the system of transitivity, with examples of material, mental and relational processes, drawn from the corpus of children and teenage picture books from the project entitled ‘Social practices in contemporaneity: multiliteracies, identities and multimodal narratives’. As a theoretical and methodological support for the analysis of texts produced in different media and social contexts, SFL can contribute to an understanding of language as a multissemiotic social practice in educational contexts.

title: Wildlife species, Ixodid fauna and new host records for ticks in an Amazon forest area, Rondônia, Brazil

description: Abstract The objective of this work was to evaluate the diversity of ticks associated with free-living animals and to investigate new host records for ticks. Ticks were collected from animals rescued during the flood of the Jamari River in the municipality of Ariquemes, state of Rondônia, North Region of Brazil. A total of 39 animals were captured, out of which 10 were amphibians, 19 were reptiles and 10 were mammals. A total of 127 ticks of the Amblyomma genus were collected from these animals, distributed among seven species: Amblyomma dissimile, Amblyomma geayi, Amblyomma humerale , Amblyomma longirostre, Amblyomma nodosum , Amblyomma rotundatum and Amblyomma varium. In addition, one specimen of Rhipicephalus (Boophilus) microplus was collected. Among these specimens, 85 were adults and 42 were nymphs, with A. rotundatum being the most prevalent species. An Amblyomma spp. larvae was also collected from a lizard (Uranoscodon superciliosus), and one Amblyomma calcaratum and one Amblyomma dubitatum were recovered from the environment, thus totaling 130 ticks. Among the Ixodidae collected from different hosts, we provide the first report for the species A. rotundatum parasitizing Rhinella major, U. superciliosus, Leptophis ahaetulla, Chironius multiventris, and Mastigodryas boddaerti, as well as of A. humerale parasitizing U. superciliosus, A. geayi parasitizing Choloepus didactylus, and Rhipicephalus (B.) microplus parasitizing Alouatta puruensis.

title: Comparative Productivity and Seed Nutrition of Cotton by Plant Growth Regulation under Deficient and Adequate Boron Conditions

description: ABSTRACT: Plant growth regulators (PGRs) potentially improve the productivity and nutritional quality of crops through modulation of morphology, physiology and nutrient dynamics within plants. However, the effect of PGRs may differ under environments with deficient and adequate nutrients. Here the role of mepiquat chloride (MC) on the yield and seed nutritional quality of cotton was explored under boron (B) deficiency and adequate conditions in a two-year field study. Mepiquat chloride was foliar-applied at different dosages (0 and 70 mg L-1) and growth stages (squaring and flowering) and B was applied into soil (0, 1, 1.5, 2 and 2.5 kg ha-1) to establish B deficiency and adequate levels. Seed cotton yield and seed nutritional quality were substantially higher under adequate B conditions, compared to B deficiency. Nonetheless, MC applications improved the seed cotton yield, seed oil yield, seed protein yield and concentration of seed mineral nutrients (N, P, K, B, Zn and Fe except for Mn) under both B deficiency and adequate conditions. Nonetheless, the improvement in all traits caused by MC application was greater under adequate B conditions (2-2.5 kg ha-1 B), compared to B deficiency conditions. Furthermore, the application of MC at squaring proved more beneficial in improving the seed cotton yield and nutritional quality, compared to the flowering stage. In conclusion, MC application improves seed cotton yield and cotton seed nutritional quality under both deficient and adequate B conditions, through an improved nutrient accumulation in seed tissues; however, the efficacy of MC is affected by B deficiency.

title: Punching shear resistance of reinforced concrete footings: evaluation of design codes

description: Abstract Punching is a possible failure mode for slender footings and it may lead a structure to ruin through progressive collapse. Although footing present different geometric characteristics, their punching shear design is based on the empirical methods used for flat slabs. This paper uses experimental results from 216 tests to evaluate the performance of design code recommendations presented by ACI 318 (2014), ABNT NBR 6118 (2014) and Eurocode 2 (2010) to estimate the punching shear resistance of reinforced concrete footings. Great dispersion between theoretical and experimental results was observed, being evident that the test system affects the punching shear capacity of footings. The more complex method proposed by Eurocode 2 resulted in a better correlation with experimental results.

title: Colorimetric Analysis of Cotton Textile Bleaching through H2O2 Activated by UV Light

description: The bleaching process is one of the steps of cotton fabric manufacture. Traditionally, the most common bleaching procedure is based on the use of a hydrogen peroxide (H2O2) solution in alkali pH associated with high temperature. In this study, we investigated the possibility of applying a photolysis technique, combining ultraviolet (UV) light and H2O2 in acidic pH to promote raw cotton fabric bleaching, without adding heat and stabilizers to the process. A colorimetric analysis was performed to assess the bleaching procedure in the samples. The experiment consisted in moistening cotton fabric samples with H2O2 and then illuminating them with UV light with different doses, ranging from 0.6 to 36 J cm-2. Our findings have shown that it is important to balance the hydrogen peroxide and the amount of delivered UV light to the cotton fabric in order to achieve a satisfactory whiteness without compromising the fabric mechanical properties.

title: HARVESTING FRUITS USING A MOBILE PLATFORM: A CASE STUDY APPLIED TO CITRUS

description: ABSTRACT Harvesting fruits and vegetables has been a challenge. Mobile platforms for harvesting vegetables and fruits have been used, but with some limitations, such as their applicability for a certain time of the year and for a specific crop. A mobile platform was initially developed for harvesting fresh market tomatoes, mainly staked in Brazil. However, after field trials, many problems were identified, such as crop use limitation and machine structure problems. Therefore, the initial project was reformulated to assume different functions, with a retractable and smaller frame and the possibility of adding on other devices, expanding crop harvest and farm use. The concept of a hybrid vehicle with one electric power generator to drive all four wheels with electric motors was kept. The main goal of this article is to describe the development of the mobile platform machine structural details and integration of electrical, hydraulic, and mechanical project and field tests performed in a commercial orange orchard, comparing harvest types, evaluating yield and machine performance. Tests with the mobile laboratory prototype show its potential application to assist harvest and to other farm operations, especially due to its mobility. Harvest productivity through machine was higher, though not significantly different from manual harvest.
