title: Rainfall erosivity in Rondon do Pará, PA, Brazil from 1999 to 2015 and projected to 2035

description: This study determined the rainfall erosivity value for the urban area of Rondon do Pará in order to provide information about the city's soil loss. The study also determined the probability of erosion occurrence and the return period projected for the next 20 years. The annual distribution of the erosivity index was analyzed and an estimate was made of the correlation between the average monthly erosivity index and the rainfall coefficient. To accomplish this, two types of rainfall data were obtained: 1) data observed by the CMORPH satellites from 1999 to 2015; and 2) data modelled by the RegCM4 model from 2016 to 2035. Erosivity was calculated based upon these monthly and annual rainfall data. Frequency distributions of erosivity values and their return periods were calculated and probability curves were plotted. Regression analyses between precipitation and erosivity were completed. In the period from 1999 to 2015, the value of the R factor of Rondon do Pará was 16,390 MJ mm ha-1h-1ano-1, with a probability of 47% of being equaled or exceeded at least once each 2.1 years. In the period from 2016 to 2015, the R value was 13,038 MJ mm ha-1h-1year-1. Highest soil losses are probable between February and January from 1999 to 2015 and between January and April from 2016 to 2035. The regression mathematical models that had the best results were the potency and the polynomial models for the years from 1999 to 2015 and 2016 to 2035, respectively.

title: the question of comumunty land Sibaúma/RN

description: AbstractThe genesis of this work came from the reflection on the spatial dynamics of capital and the capital. The expansion and incorporation of territories by capital reveal, in part, the strategies of the capitalist mode of production, which are evident in the search for conditions of accumulation, expanding the alternative use of the land that occurs in a selective and uneven. We found in this study the mechanisms that capital uses to impose its practices through the agrarian structure and the appreciation of the land market, meaning, in our view, that the reproduction of inequalities happens often through land speculation intensified with the rapid valuation of land. Thus, the spatial area will Sibaúma the community, belonging to the municipality of Tibau do Sul, located in the state of Rio Grande do Norte. Through empirical observations in Sibaúma, we see expansion strategies, incorporation and appropriation of territory by capital. As a result of this practice is occurring valuing land and the disruption of community.

title: Science and Technology in Brazilian TV: an analysis of Globo TV programing

description: Abstract In this paper, we analyze how S&T issues appears on the TV Globo, the channel with the largest audience in Brazil. The methodology of "constructed week" was used to compose a sample of two weeks (14 days), representative of six months in 2013. We recorded and watched each day, a total of 336 hours. Through a content analysis, we found out that science appeared in 7.3% of TV Globo broadcast during the period analyzed and was in several television categories, from TV news to advertising, from soap operas to talk shows. Science was more related to issues of Medicine and Health. Scientists and experts were important sources of information, but citizens were heard about these issues as well. However, we found out that scientists were less represented on TV - and, when they appeared, there were more men than women scientists. In advertising,the most frequent television category in our corpus, science was used as a way to enforce credibility to the product, highlighting the social role of science.

title: Green banana pasta diet prevents oxidative damage in liver and kidney and improves biochemical parameters in type 1 diabetic rats

description: ABSTRACT Objective In this study, the effects of a green banana pasta diet on the oxidative damage from type 1 diabetes mellitus (DM) were investigated. Materials and methods Formulations containing 25 (F25), 50 (F50), and 75% (F75) of green banana pasta were prepared and included in a 12-week diet of Wistar rats with alloxan-induced type 1 DM. The effects of these formulations in preventing oxidative damage in kidneys and liver homogenates of rats were evaluated using the TBARS assay (lipid peroxidation in liver) and the DNPH assay (protein oxidation in liver and kidneys). Furthermore, the effects of the formulations on the fasting glycemia, fructosamine levels, renal function (creatinine), liver function (enzymes aspartate aminotransferase [AST] and alanine aminotransferase [ALT]), and lipid profile (total cholesterol and fractions) in the serum of rats were evaluated in addition to the evaluation of the centesimal composition and microbiological analysis of the produced green banana pasta. Results An F75 diet prevented hyperglycemia in diabetic rats (p &lt; 0.05) compared to the diabetic rats fed a standard diet (commercial feed). Notably, the protein oxidation in both the liver and kidneys were prevented in diabetic rats on the F50 or F75 diets compared to the control group, whereas the lipid peroxidation was only prevented in the liver (p &lt; 0.05). Moreover, all formulations prevented an increase in the amount of triglycerides in the serum of the rats. The F25 and F50 diet prevented the increase of cholesterol, and the F75-based diet of ALT and fructosamine (p &lt; 0.05) supported the anti-hyperglycemic effects and the protection against oxidative damage. Conclusion The green banana pasta (F75) diet showed great potential for preventing complications associated with diabetes.

title: PHYSICAL PROPERTIES OF PEANUT FRUITS DURING DRYING

description: ABSTRACT: The present work was accomplished with the objective of evaluating the drying effect on the peanut fruits physical properties. Peanut fruits with an initial moisture content of 0.63 decimal db were dried with a temperature of 40 ºC. Bulk density, true density, porosity, thousand-grain weight, sphericity, circularity, projected area, surface area and surface/volume ratio physical properties were determined. Based on these results, it is concluded that reducing the moisture content promotes reduction in all the physical properties of peanut fruits, except the surface/volume ratio that have their values increased with the moisture content reduction. The circularity as sphericity of the peanut fruit values was reduced during the drying process.

title: Taren, eren and panton: Macuxi oral poethnicity

description: abstract Taren, eren and panton are terms from the Macuxi language that mean, respectively, enchanted word, song and narrative. Macuxi are Carib indians who designate themselves as Pemon (people). They live in the Circum-Roraima region, on the triple border among Brazil-Venezuela-Cooperative Republic of Guyana. This work proposes these three Macuxi terms as an expression of an oral poetics of this indigenous people, who are troubled by the disregard towards Brazilian oral poetics.

title: The genera Turnera and Piriqueta (Passifloraceae sensu lato) in the state of Pernambuco, Brazil

description: Abstract A taxonomic treatment of the genera Turnera and Piriqueta in the state of Pernambuco, northeastern Brazil, is presented. Fourteen species of Turnera and six species of Piriqueta were found in the Atlantic Forest and Caatinga, of which nine are endemic to Brazil. Turnera pernambucensis is threatened and restricted to the Atlantic Forest of Pernambuco, while T. joelii is a new record for the state. The species predominate in steppe savanna and semideciduous seasonal forest, but several of them grow naturally in anthropized areas. Catimbau National Park is the locality with the highest species richness. Tristyly is recorded for the first time in Piriqueta guianensis. Identification keys, descriptions, illustrations, distribution maps, and comments about habitat, flowering, fruiting, and morphological relationships are provided.

title: Vetiver growth with different fertilizations in quartzite mining tailings

description: ABSTRACT The objective of this work was to evaluate the behavior of Vetiveria zizanioides when grown in tailings from quartzite mining. A greenhouse experiment was conducted in a completely randomized experimental design with four replicates. The treatments consisted of five combinations of organic (OF) and mineral fertilization (MF) and an additional treatment of the tailings without OF or MF (control). The combinations were 0%OF/100%MF, 25%OF/75%MF, 50%OF/50%MF, 75%OF/25%MF, and 100%OF/0% MF. The doses of 100% of MF and OF were 0.025 g N, 0.025 g P2O5, 0.020 g K2O, and 5 g of corral manure per kg of quartzite tailings. V. zizanioides responded to MF at the recommended doses of 0.025 g N, 0.025 g P2O5, and 0.020 g K2O per kg of tailings. It is concluded that quartzite tailings form a favorable habitat for V. zizanioides growth, mainly after being altered by MF.

title: Wood and Briquette Density Under the Effect of Fertilizers and Water Regimes

description: ABSTRACT The aim of this study was to evaluate the effects of potassium and sodium fertilization (control: 4.5kmol.ha-1 of KCl and 4.5kmol.ha-1 of NaCl), and water regimes (100% and 63% rainfall with artificial exclusion) on wood and briquette density in Eucalyptus grandis trees at 5 years, and the application of X-ray densitometry on the quality of briquettes. Tree trunk samples were obtained to determine wood density, production and briquette density by X-ray densitometry and stereometric. The artificial exclusion of rainwater promoted an increase in wood density, and the fertilization treatments versus water availability did not affect the density of briquettes. The method used to determine the briquette density influenced the average values, with an increase of 12% in the X-ray densitometry to the stereometric.

title: Reading Aloud: Linguistic Variation and Success in Reading Early Learning

description: Abstract: In an interface between psycholinguistics and sociolinguistics, considering stylistic monitoring (speech ( oral activities ( reading aloud) and the necessary conditions for early literacy, this paper presents the reading profiles of 3rd grade students from elementary school and relates them to performance on a reading comprehension test and to the occurrence of variable features of speech in reading aloud. The results show that the reading aloud which presents variable features of speech cannot be considered “inaccurate”; instead, these features occurred only in proficient and word-to-word types of reading, and only by students who reached higher levels on the test.

title: Forests of the Iguaçu National Park: Structure, Composition, and Richness

description: Abstract Considering the importance of the Iguaçu National Park for the conservation of the Atlantic Forest and the absence of scientific or technical studies characterizing the ecology of forest species after seven and a half decades of its existence, a phytosociological survey of the arboreal vegetation was conducted to identify the various existing species and their successional stages. A total of 54 families, 135 genera, and 218 species were found in this survey. Euterpe edulis Mart. was the most frequently occurring species, which together with Aspidosperma polyneuron Müll. Arg., characterize the seasonal forests in the central and south regions of the park. In the north region, located 700 m asl, Araucaria angustifolia (Bertol.) Kuntze and Ilex paraguariensis A. St.-Hil. were observed along with some seasonal species, characterizing a transitional environment between seasonal and ombrophillous forests. In general, forests in the park were classified in advanced stages of ecological succession.

title: Differential Susceptibility of MDF and Commercial Wood to Coptotermes gestroi

description: ABSTRACT The present study evaluated the foraging and feeding preferences of Coptotermes gestroi (Blattodea: Rhinotermitidae) in wood from four forest species and Medium Density Fiberboard (MDF) in urban areas of the municipalities of Rio de Janeiro, São Gonçalo and Seropédica, RJ, Brazil. Wooden and MDF stakes were buried in the soil in the presence of C. gestroi foragers, in multiple choice assays, where the stakes remained for 15, 30, 60 and 90 days. The highest occurrence of foragers was in Alcântara 2 (São Gonçalo). In three areas, the stakes presented no foraging at any time during the exposure period. Generally, the longer the exposure period, the greater the occurrence of C. gestroi in the stakes and their loss of mass. The Pinus elliottii stakes had a greater loss of mass caused by C. gestroi, followed by the MDF, suggesting the need for preservative treatment of these materials prior to use.

title: Digital Approach for Measuring Tree Diameters in the Amazon Forest

description: ABSTRACT Buttresses and other natural structures modify the shape of stems in Amazonia and change the diameter at breast height (DBH) measured at 1.3 m at ground level. The lack of adequate measurement techniques affects negatively forest dynamics analyses and biomass estimating. The study evaluated an indirect method of measuring diameters in trees with DBH &gt; 40 cm using principles of digital photogrammetry. The results obtained with two cameras (smartphone and Sony) were compared with direct measurements using diametric tape and a ladder. The technique is adequate to measure the diameters of trees with measurement point above 2 m of ground, with a confidence interval of ±1cm. The use of photogrammetry as a supplementary tool to the diametric tape (IC ± 0.24 cm) is recommended, helping to measure trees with diameter above the reach of the technician in forest inventories.
