title: Effect of Breed and Caponisation on the Growth Performance, Carcass Composition, and Fatty Acid Profile in the Muscles of Greenleg Partridge and Polbar Breeds

description: ABSTRACT The aim of the study was to determine the impact of caponisation of Polbar (Pb) and Greenleg Partridge (Zk) breeds on the production performance, carcass composition, and the nutrient content and fatty acid profile in the breast and thigh muscles and abdominal fat. From 18 weeks of age to the end of the experiment, the Zk capons were significantly heavier than the cocks. The Zk capons had higher (p≤0.05) weight and share of breast and leg muscles. At 24 weeks of age, we noted an increase in the total content of n-3 PUFA and linolenic acid C18:3 in the breast muscles of the Zk and Pb capons. The content of PUFA and n-3 PUFA in thigh muscles and the n6/n3 ratio were reduced in the Pb capons at 24 weeks of age, compared with the Zk cocks. Caponisation of the Pb cocks had a beneficial effect on the final body weight, feed intake, and slaughter characteristics, in comparison with the non-caponised birds of this breed. A tendency towards an increased total share of PUFA and MUFA, a significantly higher content of n-3 PUFA, and a lower (p≤0.05) n-6/n-3 ratio were found for the breast muscles of the Pb capons. Both breeds are a good material for production of capons. The meat of the capons of both breeds exhibited a beneficial, higher PUFA/SFA ratio, higher n-3 PUFA and MUFA content, and a more favourable n-6/n-3 ratio.

title: Physical performance of particleboards using Castor oil-based adhesive

description: ABSTRACT Reconstituted wood panels are widely used in various branches of the wood industry, such as in the furniture sectors and various segments of urban and rural construction. In Brazil, agricultural and forestry residues are abundantly generated, making feasible the study, development and application of alternative and sustainable materials, produced from the use of these wastes. The aim of this study was to produce high-density homogenous panels with wood residues of Pinus elliottii and oat hulls (Avena sativa), pressed with two types of adhesive, castor oil-based polyurethane and melamine formaldehyde, and to evaluate the physical performance of these panels. The physical performance of the panels was evaluated based on the ABNT NBR 14810: 2006, ANSI A208.1: 1999 and BS EN 312: 2003 standards. Analysis of variance (ANOVA) was performed to test the influence of the factors percentage of oat hull, percentage of adhesive and type of adhesive, and the interactions between these factors on the physical properties of the panels. The results indicated physical properties, in some treatments superior to the requirements stipulated by the consulted standards. It was concluded that the panels produced with the castor oil-based polyurethane adhesive showed better physical performance when compared with the panels produced with the melamine formaldehyde adhesive.

title: TREATMENT OF WASTEWATER WITH HIGH FAT CONTENT EMPLOYING AN ENZYME POOL AND BIOSURFACTANT: TECHNICAL AND ECONOMIC FEASIBILITY

description: ABSTRACT The combination of 0.5% weight per volume (w/v) crude enzyme consortia produced by solid state fermentation with Penicillium brevicompactum and 27 milligrams per liter (mg/L) of rhamnolipid biosurfactant produced by submerged fermentation with Pseudomonas aeruginosa was employed to pretreat wastewater from a poultry slaughterhouse in bench upflow anaerobic sludge blanket (UASB) bioreactors. One bioreactor was fed with untreated wastewater (Control) and another with pretreated wastewater (Test). Under an organic loading rate of 11 kg COD/m3.d, the Test bioreactor showed higher specific methane production (67.8 mL CH4 (STP)/g COD removed), higher chemical oxygen demand (COD) (91.2%), and oil and grease (O&G) (95.8%) removal than the Control bioreactor, which produced 36.1 - 16.9 mL CH4 (STP)/g COD removed with 72.5% COD removal and 48% O&G removal. The Control bioreactor experienced five clogging episodes due to the accumulation of fat on the surface, while the Test bioreactor operated without operational problems. The scum of the Control bioreactor contained more than 10 times higher quantities of fat than the Test bioreactor. The economic analysis indicated that such alternative technology has lower costs than conventional technology.

title: Dust of progress calls for passage: nature and development images in the Amazon Rainforest

description: ABSTRACT Between 1958 and 1960, the main project of the government of Juscelino Kubitschek for the Amazon region was built: the Transbrasiliana, or Belém-Brasília Highway. With the opening of more than two thousand kilometers of road in the middle of the Amazon rainforest, the project was criticized by opposition media. Faced with this question, the press in favor of the Kubitschek government was activated to produce materials favorable to the enterprise. This article aims to analyze the images produced by these reports. Through them, it is also possible to analyze the relationships between the development projects of this period and the nature, as well as how the Amazon region was seen by the Kubitschek government.

title: Formation of ternary organic acids-Fe-P complexes on the growth of wheat (Triticum aestivum)

description: ABSTRACT Phosphorus (P) reacts with chemical and mineralogical constituents in the soil, mainly in tropical and subtropical soils. Therefore, strategies have been used to reduce the adsorption of P to the soil, among them, the formation of complexes that could decrease P adsorption to the soil. Two experiments were carried out to evaluate the formation of organic acid-Fe-P complexes in the laboratory and the efficiency of these complexes on the growth of wheat plants (T. aestivum) grown under greenhouse conditions. In experiment 1, seven low-molecular-weight organic acids (OA) were selected and a protocol for the formation of complexes between organic acid and Fe3+ at pH 4.0 was performed. After stirring, P was added to the organic acid-Fe complex to form the ternary complex. The remaining P was evaluated to determine the amount of P in the complex. In experiment 2, the three OAs which had the largest amount of complexes were selected, together with a treatment with soluble P and a control. Wheat was grown in potted soil in a greenhouse for 34 days. The amount of ternary organic acid-Fe-P complexes formed varied from 5 to 42% of the added P. However, when these complexes were added to the soil, in treatments with greater amount of complex formed there was lower growth of wheat. Thus, the ternary complex with organic acid-Fe-P has little effect on the performance of wheat plants.

title: DENSITY, VISCOSITY AND EXCESS PROPERTIES OF BINARY MIXTURES OF PROTIC IONIC LIQUID (2-HDEAF, 2-HDEAA) + WATER AT DIFFERENT TEMPERATURES

description: Abstract Over the last decade, ionic liquids (IL) have attracted considerable attention for their potential to replace traditional volatile organic solvents due to their well-known physico-chemistry properties. This is an important topic for industrial applications today, and have been the subject of extensive literature studies. Nevertheless, there is still a lack of experimental thermodynamics data on aqueous mixtures, i.e., ionic liquids + water, especially volumetric and transport properties. These data could provide essential information about interactions and molecular phenomena in such mixtures. To investigate volumetric and transport properties for ionic liquids + water, density and viscosity data of the protic ionic liquids 2-hydroxydiethanolamine formate (2-HDEAF), 2-hydroxydiethanolamine acetate (2-HDEAA), water and their binary mixtures were measured at T = (293.15 to 343.15) K and atmospheric pressure. Excess molar volumes and deviation of viscosity were computed from experimental density and viscosity values and were fit to the Redlich-Kister equation. We observed a negative behavior for both ionic liquids + water mixtures that can be attributed to a shrinkage of the mixtures.

title: “Science Popularly Treated, and not Science Professionally Discussed Will Be our Writing System” The Press and the Popularization of Science in Brazil in the Second Half of the Nineteenth Century

description: Abstract In the second half of the 19th century, the concept of ‘scientific popularization,’ which referred primarily to the idea of communicating science to lay people, was used considerably in Brazil. Popularizers of sciences sought, through books, magazines, journals, conferences, and exhibitions, to communicate the knowledge of science to the general public, especially to the working class and children. The number of periodicals expanded, covering a wide variety of themes and publics. Imbued in these publications was the idea of science for all and the conviction that the cultivation of science was an instrument to obtain knowledge about new nations and to educate the population. Here we will highlight some Brazilian journals which, in the second half of the nineteenth century, were edited and/or written by popularizers, the so-called ‘intellectual mediators,’ who dedicated their pages to the popularization of Science. These include A semana. Jornal litterario, scientifico e noticioso (Rio de Janeiro, 1855); Academia popular. Semanário de Instrucção e Recreio para o Povo (Recife, 1863); Illustração Popular (Rio de Janeiro, 1876); Revista do Rio de Janeiro (Rio de Janeiro, 1876); O Vulgarisador. Jornal dos conhecimentos uteis (Rio de Janeiro, 1877); Sciencia para o povo. Serões instructivos (Rio de Janeiro, 1880); and Barão de Macahubas. Periodico scientifico, litterario e noticioso (Bahia, 1886).

title: THE USE OF COMPRESSED FLUIDS TO OBTAIN BIOCOMPOSITES FROM PALM OIL FIBER (Elaeis sp.)

description: Abstract Empty fruit bunch fiber (EFBF) is a lignocellulosic waste generated by the palm oil agribusiness. The amount of EFBF produced is equal to the oil obtained, and it can be used as raw material to obtain biocomposites. The objective of this work is to fragment the EFBF employing pressurized fluids in a semi-continuous system to obtain different biocomposites. For this, pure water and a mixture of water/carbon dioxide were employed as solvent to obtain sugar monomers and a mixture of compressed water/ethanol (1:1 vol.) to obtain crystalline cellulose. The experiments were conducted in the temperature range of 120 to 240 ºC, using reaction times between 5 and 15 min at 60 bar, and solvent flow rate of 0.75 mL.min-1. A maximum of 30.47 mg.mL-1 of xylose was obtained at 210 ºC for 15 min of reaction with pure water as solvent. The best condition to obtain crystalline cellulose was 240 ºC for 30 minutes of reaction, obtaining 38.2% of cellulose from palm oil EFBF.

title: Comparison of tools for assessing fatigue in patients with heart failure

description: ABSTRACT Objective: To compare the distributions of measurements of the Dutch Fatigue Scale (DUFS), Dutch Exertion Fatigue Scale (DEFS), and Fatigue Pictogram tools, according to the New York Heart Association (NYHA) Functional Classification and left ventricular ejection fraction (LVEF). Method: Methodological, cross-sectional study with 118 patients with heart failure. Variance analysis, Pearson's correlation, and Fisher's exact tests were carried out, with a significance level of 0.05. Results: There was an increase in the DUFS and DEFS means with worsening of the NYHA-FC (p&lt;0.001, for both tools). Correlations among the LVEF resulted in positive and weak magnitude for the DEFS (r=0.18; p=0.05) and for the DUFS (r=0.16; p=0.08). Just the item A on the Fatigue Pictogram had an association with the NYHA-FC (p&lt;0.001) and the LVEF (p=0.03). Conclusion: Three tools detected worsening in fatigue levels according to the illness severity assessed by the NYHA-FC.

title: OPTIMIZATION OF KINETIC LUMPING MODEL PARAMETERS TO IMPROVE PRODUCTS QUALITY IN THE HYDROCRACKING PROCESS

description: Abstract In this study a typical continuous lumping model with five parameters has been used for kinetic modeling of thermal and catalytic hydrocracking. Model parameters have been optimized according to experimental product distributions using a particle swarm optimization (PSO) algorithm. Experimental data from the hydrocracker setup have been employed to validate the proposed model. In this setup hydrogen and vacuum gasoil feed were introduced from the top of a vertical reactor and, after passing through a catalyst bed, the liquid and gas products were separated and analyzed. Temperature of the reactor was adjusted in the range of 440-470°C for thermal hydrocracking, and 410-430°C for catalytic hydrocracking. Liquid hourly space velocities (LHSV) were in the range of 0.5-1.5 feed flow rate per catalyst volume in both sets of experiments. Results of optimization showed that the parameters were only temperature dependent. The comparison between model results and experimental data indicates that the model is capable of predicting product yield with maximum errors of 0.986 and 0.041 for RMSE and AARE values, respectively.
