title: Optimization of the use of axial turbines in small hydro power plants in the Amazon

description: ABSTRACT The technical and economic optimization of electricity generation by small hydropower plants (SHP) with a low head in the Amazon is studied, in order to contribute to hydro energy studies of these SHP. The flow duration curves (FDC) needed to design hydropower generation were simulated using the Nonlinear Hydrological Model Simple with Sigmoidal Gain Factor (SVM). Due to seasonality inherent to the Amazon, SHP generation was considered using two axial turbines operating in parallel. For technical optimization the CARTHA program was used to obtain the axial turbine load curves, allowing the study of the influence of the type of regulation and the relationship of the powers of the turbines on the energy efficiency of SHP. Plants with double regulation turbines presented an efficiency of 80%, for rotor regulation 72% and for distributor regulation 65%. Three market scenarios were studied for economic optimization: sluggish, neutral and hot. The best technical and economic results were obtained for SHP with total power on the order of 30MW, equal turbines equipped with rotor regulation only, sluggish market, resulting to the return period of 1.7 years and profitability of 222%.

title: Influence of a heating device and adhesive temperature on bond strength of a simplified ethanol-based adhesive system

description: Abstract Introduction Increased adhesive temperature has been reported to promote solvent evaporation, reduce viscosity, and improve monomeric permeation into dentin. Objective The aim of this study was to determine the influence of different heating methods on the microtensile bond strength of an etch-and-rinse adhesive to dentin. Material and method Twenty-four caries-free extracted human third molars were transversally sectioned to expose a flat dentinal surface. The samples were etched with 37% phosphoric acid gel and divided into three groups (n = 8): 1) Control - the adhesive system (Adper Single Bond 2; 3M ESPE) was applied at room temperature; 2) Warming device - the adhesive was warmed to 37°C in a custom device before application; and 3) Warm air - the adhesive was warmed to 50°C with an air jet after application on dentin. The specimens were restored with a composite resin (Filtek Z250 A2, 3M ESPE) and prepared for microtensile bond strength testing, after 24 h in water storage. The data were subjected to one-way ANOVA and Tukey's test (p &lt; 0.05). Result There was no significant difference among the groups (p &gt; 0.05). The mean bond strength values in the control, the warming device, and the warm air groups were 48.5 (± 5.2), 40.35 (± 4.9), and 47.2 (± 5.3) MPa, respectively (p = 0.05). Conclusion The different heating methods had no significant influence on the immediate microtensile bond strength of an etch-and-rinse ethanol-based adhesive to dentin.

title: Molecular Imaging in the Diagnosis of Infectious Endocarditis - the Role of PET and SPECT

description: Abstract 18-fluorine-fluorodeoxyglucose positron emission computed tomography (18F-FDG PET/CT) and singlephoton emission computed tomography (SPECT) using radiolabeled white blood cells (WBC) are non-invasive techniques widely used in the diagnosis of infections, like endocarditis. The aim of our paper was to provide a systematic review of the published data on the use of 18F-FDG PET/CT and SPECT in infective endocarditis (IE). A comprehensive literature search of the PubMed/ MEDLINE, Scopus, Embase and Cochrane library databases was conducted to find relevant published articles about the diagnostic performance of SPECT using WBC and 18F-FDG PET/CT in the diagnosis of infectious endocarditis. Twenty papers were included, with a total of 1,154 patients (166 studies with WBC SPECT and 988 with 18F-FDG PET/CT). From the analyses of the studies, the following results were obtained: both SPECT and PET/CT had good diagnostic accuracy in the study of endocarditis. 18F-FDG PET/CT had good specificity (85.8%) and lower sensitivity (68%), with high heterogeneity among the studies; WBC SPECT/ CT had an overall sensitivity of 80% and specificity of 98%. Specific preparations for PET/CT can affect the diagnostic accuracy of the test. Both 18F-FDG PET/CT and WBC SPECT are useful for the diagnosis of IE, and WBC SPECT appears to be slightly more specific than 18F-FDG PET/CT. A specific diet could influence the diagnostic performance of PET/CT.

title: Radiographic analysis for the evaluation of polyembryony in Swingle citrumelo seeds

description: Abstract: The polyembryony rate is a very important factor to consider when choosing a commercial rootstock. Currently, automated systems are used to improve seed quality analyses. X-ray testing is a fast, simple, non-destructive, high-precision test that allows to examine in detail the internal morphology of the seeds to identify damaged areas, their location and types of damage. In this context, the present research aimed to verify the possibility of using X-ray test to evaluate the polyembryony in Swingle citrumelo seeds. Seeds from seven lots were submitted to X-ray tests, direct method (embryo counts) and indirect method (germination). According to the results obtained, it was observed that there was a high coincidence between the number of embryos per seed analyzed using X-ray test and the direct method. Radiographic image analysis is efficient to evaluate the polyembryony in seeds of Swingle citrumelo.

title: Academic Literacy and Genres in University Learning Communities

description: Abstract The study of genre through different perspectives has contributed to a better understanding of how writing performs a major role in the enculturation process students must undergo when entering the university context. Considering that written genres instantiate the specific practices of disciplines, their different ways of doing and knowing (Carter, 2007), this study aims, by means of a qualitative approach, at exploring the way literacy in academic writing is addressed, according to the discourse of teachers and students of five different disciplinary communities at a Chilean university, based on the approach to their particular genres. The results reveal that, in the communities addressed, literacy in academic writing is conceived under two distinctive orientations: a formative and a prescriptive one, each of them associated to genres displaying expert and instructional characteristics, respectively.

title: GREENHOUSE GAS FROM CASTOR BEAN PRODUCTION AND THEIR SUBPRODUCTS

description: ABSTRACT: The largest production of castor bean (Ricinus communis L.) focuses on Bahia savanna, where the change of land use to their cultivation has been considered a strategy of degraded areas recovery. However, changes in the native soil can arise environmental impacts as greenhouse gases (GHG) emissions. We have assumed that higher GHG emissions come from a change of land use for castor bean cultivation and their sub-products contribute to GHG emissions. The objective of this study was to make the inventory of the emission of GHG resulting from the castor bean cultivation and their sub-products. It was done a study in the municipality of Irecê-BA and were evaluated: changes in carbon (C) soil stocks in cultivated areas with castor bean and Local native forest; a number of senescent leaves and the biomass produced epigeal; GHG emissions from the sub- products of castor bean. The results showed that the sum of senescent leaves and epigeal biomass obtained by castor bean pruning is more than 1.6 Mg ha-1ano-1 and the castor bean residues used in this soil presented N2O emissions close to 600 µg m-2. The emissions from the use of castor oil biodiesel represented less than 10% of the emissions. The change in land use handled high emissions of greenhouse gases, accounting for 87% of the total in CO2eq. Compared to emissions estimated for sugarcane ethanol, castor biodiesel showed emissions 32% lower.

title: USE OF ALTERNATIVE EXTENDERS AND TEMPERATURES IN LONG TERM STORAGE OF BOAR SEMEN

description: Abstract The use of appropriate extenders is important for the success of an artificial insemination program. The objective of this study was to evaluate the efficiency of alternative extenders for swine semen at different temperatures (17 to 10 °C). The following extenders were used: Beltsville Thawing Solution (BTS), powdered coconut water (ACP-103®), and skimmed milk powder (LPD). The 50 ejaculates were analyzed daily, in natura and after dilution, during the 5-day period of semen preservation (D0 to D4), regarding spermatic vigor and motility. Acrosome integrity and sperm viability were evaluated on D0 and D4. Data were analyzed using Mann-Whitney, Students, Tukey and chi-square tests (p&lt;0.05). The LPD extender at 10 °C presented higher motility and sperm vigor compared to BTS and ACP until D2, and to treatments stored at 17 °C. Acrosome vitality and integrity remained higher (p&lt;0.001) with LPD at 10 °C on D0 and D4. LPD showed to be a good extender for the swine semen at lower temperature (10 °C). Furthermore, it provided better protection to sperm cells, by allowing greater integrity and vitality of the acrosome.
