1. Comparison between barley malt protein quantification methods
Abstract Brazil imports about 60% of all the malt used by the brewing industry which is spread throughout the country. Even though it is an agricultural country, only a small portion of the barley production has the characteristics to produce barley malt for brewing. Seeking supply to the ever-growing demand and reducing the dependency on other countries and

2. Prediction of quality parameters of food residues using NIR spectroscopy and PLS models based on proximate analysis
Abstract The real-time prediction in biorefinery industries has become essential. Models using partial least square regression (PLS) were developed to predict moisture, ash, volatile matter, fixed carbon and organic matter of coconut and coffee residues. In this study, 49 samples were collected and near infrared spectroscopy were applied to predict moisture,

4. Enrichment of Copper, Lead, and Tin by Mechanical Dry Processing of Obsolete Printed Circuit Board Residues
Waste printed circuit boards (WPCB) residues were mechanically processed to concentrate their metal content aiming to reduce costs of the subsequent recovery of copper, tin, and lead. A fully dry route was proposed to avoid the generation of liquid effluents that would require additional treatment. Firstly, 10.7% of the residue was segregated by magnetic sep

5. DESENVOLVIMENTO DE METODOLOGIA DE REVELAÇÃO DE IMPRESSÃO DIGITAL LATENTE COM CHALCONAS
Fingerprints are unique for each individual contributing to human identification in forensic cases. Visualization of latent fingerprints usually involves the use of a chemical substance that creates a contrast between fingerprint residues and the surface on which the print was deposited. Commercial powders used as fingerprint developers by papilloscopy have

6. Equipments to manage soil and irrigated rice straw for the sequential sowing of soybean in tropical floodplains1
RESUMO A presença de palha dificulta a semeadura de soja cultivada em sucessão a arroz, em áreas irrigadas por inundação. Objetivou-se avaliar a combinação de configurações de colhedora de arroz e operações subsequentes na demanda operacional e energética do manejo da palha de arroz e na rugosidade superficial do solo, visando ao cultivo da soja

7. Properties and Morphology of Polypropylene/Big Bags Compounds
In this work, compounds based on two grades of polypropylene (PP), i.e., PP H503 or PP H103 with residues of Big bag fabrics (RBB) were processed in a corrotational twin screw extruder with RBB content ranging from 10% to 50% of the weight. Then, their thermal properties were investigated through Differential Scanning Calorimetry (DSC) and Thermogravimetry (

8. Impact and management of diseases in the propagation of fruit plants
Resumo Mudas bem formadas e sadias são o sucesso econômico na fruticultura. A sanidade das mudas deve ser assegurada durante o processo de produção, evitando a morte de plantas e a disseminação de patógenos para novas áreas, tendo como consequência o aumento do custo de produção e a redução da produtividade, podendo determinados patógenos, inv

9. CAROTENOID-PRODUCING YEASTS IN THE BRAZILIAN BIODIVERSITY: ISOLATION, IDENTIFICATION AND CULTIVATION IN AGROINDUSTRIAL WASTE
ABSTRACT Different yeast strains from forests located in southern Brazil, with potential to produce carotenoids, were isolated. Three microorganisms were selected as potential carotenoid producers. Sporiodiobolus pararoseus, Rhodotorula mucilaginosa and Pichia fermentans were grown in Yeast Malt (YM) medium and the carotenoids produced identified as cryptoxa

10. Characterization of new selective coatings, made of granite and chrome, for solar collectors
ABSTRACT The depletion of fossil fuel reserves and climate change caused by atmospheric pollution has led the human being to seek alternatives that are less damaging to the environment. The concern and the awareness of the population open space for the study of renewable energies to be deepened, among them the best use of solar energy. The use of alternative

11. Balanço de Energia, Emissão Foliar e Eficiência do Uso da Radiação pela Cana-de-Açúcar em Cultivo sem e com Palhada
Resumo Nas últimas décadas houve mudança no sistema de colheita e manejo da palhada em canaviais de todo o Brasil, visando atender a legislação vigente e reduzir custos. A deposição de resíduos culturais sobre o solo, contudo, modifica as características micrometeorológicas do ambiente. Este trabalho reporta um estudo conduzido em Juazeiro-BA, para

12. Phosphate Sources and Filter Cake Amendment Affecting Sugarcane Yield and Soil Phosphorus Fractions
ABSTRACT: The use of mineral phosphate fertilizers associated with organic residues can improve fertilizer use efficiency and consequently decrease their usage costs. Soil application of filter cake (FC) can provide nutrients and enhance physical quality. This study aimed to evaluate the effects of different phosphate fertilizers [rock phosphate (RP) and tri
