1. Study of Catalytic Pyrolysis of Biomass Sorghum (Sorghum bicolor L. Moench) Using Design of Experiments and Surface Response Methodology
This study proposes a screen of variables that have an influence on the modification of the bio-oil chemical composition as a unique critical quality attribute (CQA) throughout the pyrolytic process (zeolite, ZSM-5) by using a 24 full factorial design, followed by optimization through a response surface methodology (RSM) based on central composite design (CC

2. Water uptake of soybean pods and seeds with different lignin contents
ABSTRACT The identification of pod- and seed-related traits of soybean genotypes and their interaction with water uptake can be applied in breeding programs with a view to establishing cultivars developed for the production and maintenance of high-quality seeds. The objective was to evaluate the water uptake of pods and seeds of soybean cultivars with differ

3. Multivariate Optimization of Extraction Variables of PAH in Particulate Matter (PM10) in Indoor/Outdoor Air at Campos dos Goytacazes, Brazil
Polycyclic aromatic hydrocarbons (PAH) are products of incomplete combustion of biomass and fossil fuels, that are produced on a larger scale by anthropogenic sources. Burning sugarcane plantations can be a source of atmospheric PAH in regions where this culture predominates. Campos dos Goytacazes, Brazil, is surrounded by sugarcane crops that still use fire

4. Optimization and characterization of vinegar produced from rice bran
Abstract The vinegar is a millenary food, appreciated by consumers worldwide. The rice bran is a rice-processing by-product produced in a large scale, mainly employed in feed. This study describes a method for defatted rice bran (DRB) vinegar production by submerged fermentation, with optimized aeration and stirring conditions, evaluating its physico-chemica

6. Obtaining and characterization of anthocyanins from Euterpe oleracea (açaí) dry extract for nutraceutical and food preparations
Abstract The main constituents of the Euterpe oleracea Mart., Arecaceae, fruits (açaí) are anthocyanins. This paper aimed to standardize the extraction process and characterize an anthocyanin-rich dry extract obtained from this fruit. A 23 full factorial design was used. The volumes of ethanol 92% and acetic acid and the extraction time were used as factor

7. Effect of resin content and pressing temperature on banana pseudo-stem particle boards properties using full factorial design
Abstract: The volume of global gross banana exports reached a record of 117.9 million tonnes in 2015 (FAO 2017), which agro-industrial wastes derived as the pseudo-stem, rachis and leaves do not have an industrial application instead they are discarded. This research study applies full factorial design and response surface methodology to determine the effect

8. Luminosity levels and substrates composition on Bermuda Grass development
Resumo Gramado é parte fundamental na composição de campos esportivos. Alguns aspectos devem ser levados em consideração no processo de escolha da espécie a ser utilizada, como a utilização do gramado (tolerância ao pisoteio), manejo do gramado, condições físico-químicas do solo e tolerância ao sombreamento. Com a realização de eventos esport

9. Effects of nickel fertilization on soybean growth in tropical soils
ABSTRACT Although nickel (Ni) is recognized as plant nutrient since the turn of the 21st century, uncertainty remains about its optimum application rates and forms. This paper focuses on Ni application in soils, relating to its effect as a plant micronutrient. Specifically, the effect of Ni on the activity of urease in soybean plants is examined. The effects

10. Agronomic performance of beet cultivars as a function of phosphorus fertilization
RESUMO A carência do fósforo no solo afeta o desenvolvimento e a produtividade das plantas; no entanto, para que as mesmas expressem todo o potencial, faz-se necessário o fornecimento deste nutriente. Objetivou-se no trabalho definir doses adequadas de fósforo, que maximizem a produtividade e qualidade de quatro cultivares de beterraba, e identificar ent

11. Determination of Antibiotics Residues in Milk Using a QuEChERS Method Using Full Factorial Design and Liquid Chromatography-Tandem Mass Spectrometry
This study evaluated different methods of extraction based on quick, easy, cheap, effective, rugged and safe (QuEChERS) method for analysis of the antibiotics ceftiofur, cloxacillin and enrofloxacin in milk using ultra-performance liquid chromatography-tandem mass spectrometry. The QuEChERS acetate method has been shown to be inefficient for extracting such

12. Environmental and physiological effects on cross-ability and seed production of greenhouse cucumber
Resumo: A qualidade das sementes depende de muitos fatores. Neste estudo, foram realizados dois experimentos independentes para investigar os efeitos do horário da polinização, espaçamento dos nós cruzados, idade da flor masculina, número de cruzamentos em cada planta e deleção ou não de outros frutos dos nós sobre a capacidade de cruzamento e prod
