title: PHYSICAL AND PHYSIOLOGICAL ATTRIBUTES OF SAVED COWPEA SEEDS USED IN THE BRAZILIAN SEMI-ARID REGION

description: ABSTRACT This study evaluated the physical and physiological attributes of saved cowpea seeds (Vigna unguiculata L. Walp.) used in the Brazilian semi-arid area and compared them with certified seed varieties. The study tested 37 saved seed samples from the state of Rio Grande do Norte and two varieties of certified seeds (“BRS Guariba” and “BRS Pujante”) from the production field of Embrapa Products and Market, Petrolina, PE, Brazil. The seeds were tested for moisture, hectoliter weight, weight of 1,000 seeds, and physical purity to evaluate the physical quality. Germination, first germination count, field emergence, emergence rate index, shoot dry mass, and accelerated aging were tested for physiological quality. The saved cowpea seeds showed great differences, suggesting the influence of genetic variability and different growing environments. The use of saved cowpea seeds by small farmers in the semi-arid areas of Northeastern Brazil is impractical, because these seeds have inferior physical and physiological qualities compared to certified cowpea seeds.

title: Prebiotic and antibiotics as additives in the pre-and post-placement broilers

description: SUMMARY This study aimed to evaluate the use of feed containing prebiotic or antibiotic, in the pre and post accommodation on the performance of broilers. We used 720 day-old chicks, males, Cobb-500 strain, distributed in randomized blocks with four treatments with six replicates of 30 birds each. The treatments consisted of: Antibiotic - birds fed diet with added antibiotics in pre- and post-housing; Prebiotic - birds fed feed with added prebiotic in pre and post accommodation; No aditivo- birds fed without feed additive in pre- and post-housing; Fasting - birds fasted in the pre-stage housing and feed intake with antibiotics in the post-stage housing. The provision of pre-feed accommodation within the transport boxes started in the incubator, and the pre-accommodation time of 24 hours. For productive performance analysis of bird, have assessed the variables of: average weight, feed intake, weight gain, feed conversion, production factor and production viability. The use of pre-accommodation prebiotic or antibiotic property diet resulted in significant improvements (p&lt;0.05) in body weight and weight gain of chicks in step 1 to 7 days. This happened regardless of the use of additives in feed provided the pre-housing and pre-initial phase. The final performance of broilers was not affected (P&gt; 0.05) for the use of additives in the pre and post accommodation. Thus, it is concluded that the supply of prehousing portion is not required for broilers tested in fasting period.

title: Constructed Wetlands Systems Batch: removal of Biochemical Oxygen Demand and pH regulation for treatment dairy effluent

description: This work assessed the effectiveness of using constructed wetlands (CW's) to treat dairy effluent. The purpose of the research was to evaluate the influence of substrates and cultivated plants on the efficiency of Biochemical Oxygen Demand (BOD) removal and pH regulation in six experimental units operating at pilot scale. Six CW's for dairy sewage treatment were constructed in 100-liter High-Density Polyethylene Ethylene (HDPE) tanks. Three constructed wetlands containing fine gravel (0 mm) and another three with a mix of 20% sand and 80% fine gravel (0 mm) were used in the filtering stage. Four experimental units were planted with the macrophytes Typha dominguensis (cattail) and Hedychium coronarium (pond lily), the selected plants for this study, and two others were maintained as control units. A minimum average of 77.8% and a maximum of 95.2% BOD efficiency removal were achieved and a pH range of 5 to 9 was maintained as required by the Brazilian Resolution CONAMA N. 430 /2011 in order to release the effluent into a waterway. The six treatments showed similar removal of biodegradable carbonaceous compounds with no significant differences between the treatments at a 95% confidence level. This work showed that CW's operating in batch can be used to treat dairy raw water for BOD removal and pH regulation.

title: A concept-environment for computer-based augmentative and alternative communication founded on a systematic review

description: AbstractIntroductionLocked-In Syndrome is admittedly the worst case of motor and speech impairment, it seriously damages the ability of oral and gestural communication of patients. In recent years, alternative and augmentative communication technology has provided resources to restore these patients' ability to communicate.MethodsIn order to relate and classify the main methods with that purpose, this work conducted a systematic review on several journal databases.ResultsWe found 203 related papers and 55 of them were selected to compose the study. After that, we classified them into three major groups and we identified the main difficulties when using each approach.ConclusionIn order to overcome these difficulties, we propose a new system concept to develop an adaptive, robust and low cost communication environment. The proposed system is composed of five modules: data entry, communication, aid to the caregiver and external interaction.

title: State Education Councils in New State Education Plans

description: Abstract: This exploratory and descriptive study, based in the analysis of content, aims to examine the role that the State Education Councils (CEEs) eventually occupies in the State Education Plans (PEEs) aligned to the PNE 2014-2024, whether in relation to the state management of their education systems, either, more specifically, in terms of the development and implementation of the plan itself. As a more general conclusion, it was observed that the CEEs feature, since their creation, a declining historical trajectory, whose effects are observed in these plans: in the absence of leadership for their preparation, in draining of the competences as bodies of the State Education Systems, and in terms of the fragility of the system in supplying its structure.

title: Evapotranspiration from Remote Sensing to Improve the Swat Model in Eastern Amazonia

description: ABSTRACT In this study, we estimated the evapotranspiration from orbital images - MODIS (Moderate Resolution Imaging Spectroradiometer) for assimilation in the hydrological modeling of the SWAT (Soil Water Assessment Tools) model. The data used include the period between October 2003 and December 2006 of the sub-basin of the Lajeado River, located in the Tocantins-Araguaia River basin in Tocantins state. Overall, the results of the use of heat flows estimated by remote sensors in the SWAT model can be considered satisfactory. The values of the COE (coefficient of efficiency of Nash-Sutcliffe) ranged from -0.40 to 0.91 in the comparison with the daily flow data and from 0.17 to 0.77 with the monthly flow data, with the assimilation of evapotranspiration from orbital images. These results indicate benefit to the model adjustment due to improvement in the data assimilated of approximately 0.91 in the COE on daily scale and 0.60 in the CEO on monthly scale.

title: Macroeconomic and Institutional Factors, Debt Composition and Capital Structure of Latin American Companies

description: ABSTRACT The objective of this research was to examine the influence of macroeconomic and institutional factors when determining the capital structure of Latin American companies from 2009 to 2014, and also analyze if the significance of these factors to explain the capital structure of the companies is changed taking into account the financing composition. We used hierarchical linear modeling to process data. The main results pointed that, both the representative variables of characteristics of the firm and representative variables of countries are important determinants of the capital structure of the companies. However the variables of the firm explain a much higher percentage of variance of leverage. Thus, we emphasize that there is still much to be done in order to analyze the effects of macroeconomic and institutional factors. We expect that this study has created contributions to the national literature, by using a theoretical and also econometric approach that has not been much explored so far. As well as for market agents to examine the determinants of capital structure, considering the institutional aspects.

title: The Many Graveyard Books: Artistic Collaborations and Possible Multiple Readings in Illustrated Works

description: Abstract: This article investigates how diverse layers of meanings can be seen in different interactions of the same work, as it is illustrated or adapted by different artists. Starting from a single source material, Neil Gaiman’s The Graveyard Book (2008), we analyze two versions and one adaptation of the text: one novel illustrated by Dave Mckean (2008) and another by Chris Riddell (2009); and a graphic novel (2014), adapted by P. Craig Russell. We draw our analysis from authors in the fields of Children's Literature and Comics Studies to discuss the construction of meanings between the interplay of written and visual texts. Such interactions have a range of variation taking into consideration both the format of the work (novel or graphic novel), the choice of a scene to be illustrated, and stylistic approaches.

title: ORGANIC MATTER AND SOIL FERTILITY IN DIFFERENT SUCCESSIONAL STAGES OF SEASONAL SEMIDECIDUAL FOREST

description: ABSTRACT The accumulation and transformation of organic matter in the soil are fundamental for the maintenance and improvement of the chemical, physical, and biological attributes of the soil, and consequently, for the tropical forests functioning. The objective of this study was to evaluate the influence of secondary forests with different successional stages on soil organic matter, carbon and nitrogen stocks, and soil fertility. Three areas of seasonal semideciduous forest, located in Pinheiral - RJ, with different successional stages were selected: initial stage forest - ISF, medium stage forest - MSF, and advanced stage forest - ASF. The values of total carbon and nitrogen, C and N stocks, δ13C (‰) isotope, chemical and granulometric fractionation of soil organic matter, and soil fertility were determined. Based on the values of δ 13C (‰), it was verified that most of the soil carbon of the different successional stages comes from forest species (C3 plants). The areas with the highest succession time (MSF and ASF) possess higher levels of carbon and nitrogen contents and stocks, and carbon associated with minerals compared to ISF. In addition, ASF showed increased phosphorus, fulvic acid, humic acid, whereas soil density exhibited reduced values when compared to that of other areas. The MSF showed, in general, greater fertility of the soil. This study emphasizes the importance of secondary forests that, even in the initial stages of succession, have great potential to store and stabilize organic carbon in the soil.

title: Reproductive biology and production of seeds and seedlings of Campomanesia pubescens (DC.) O. Berg.

description: Abstract: Pollination is a fundamental process to produce food and maintain biodiversity in natural areas, since the production of seeds is related to its efficiency. Studies can determine the influence of reproductive systems on seed and seedlings quality and, consequently, on the structure of populations, helping the management, plant breeding and preservation of species. Campomanesia pubescens (DC.) O. Berg. (guabiroba) is a Brazilian shrub, pollinated by bees and occasionally by dipterans. This work aimed at evaluating the influence of pollination and reproductive system on seed production and germination and on the seedlings quality of C. pubescens. Phenology and floral biology were studied, and fruits from controlled pollinations were collected, in the Mogi Guaçu Biological Reserve, São Paulo State. The germination of seeds originated from self- and cross-pollination were analyzed, as well as the development of seedlings up to 180 days after germination. Seeds from self-pollination produced seedlings with lower development than the ones from cross-pollination, and they were more susceptible to mortality in laboratory and in greenhouse.
