Experimental design and data analysis: methods for the response optimization and applications using R. Author(s): OLIVEIRA, T. A.; LEAL, C.; LIMA, R. Repository: BDPA Publication year: 2015
Two-stage inference in experimental design using DEA: an application to intercropping and evidence from randomization theory. Author(s): GOMES, E. G.; SOUZA, G. da S. e; VIVALDI, L. J. In this article we propose the use of Data Envelopment Analysis (DEA) measures of efficiency, under constant returns to scale and input equal to unity, in the analysis of multidimensional nonnegative... ...

Chromium speciation in organic fertilizer by cloud point extraction and optimization through experimental Doehlert design as support for legislative aspects. Author(s): SÁ, I. P. de; SOUZA, G. B. de; NOGUEIRA, A. R. de A. Brazilian and EU legislation establishes 2 mg kg?1 as the maximum limit of Cr(VI) in organic fertilizers. A procedure involving chromium speciation was developed. With this approach, the interference... ... Repository: BDPA Publication year: 2021
Use of an experimental design for optimizing the formulation of a clarified fruit juice mixture. Author(s): NASCIMENTO, R. M.; ROSA, L. O. L.; FREITAS, D. G. C.; MATTIETTO, R. A.; MATTA, V. M. Repository: BDPA Publication year: 2012
Design of experimental design as a tool for the processing and characterization of HDPE composites with sponge-gourds (Luffa-Cylindrica) agrofiber residue. Author(s): SOUSA, A. M. F.; ESCÓCIO, V. A.; PACHECO, E. B. A. V.; VISCONTE, L. L. Y.; CAVALCANTE, A. P.; SOARES, A. G.; FREIRE JUNIOR, M.; MOTTA, L. C. C.; BRITO, G. F. C. Sponge-gourd (Luffa-Cylindrica) agrofiber residue (LC)-HDPE composites were manufactured by extrusion and injection moulding. The effects of fiber content, fiber size, screw speed and barrel zones tem... ... Repository: BDPA Publication year: 2013
Production of grape pomace extracts with antioxidant properties: a study based on process optimization by experimental design. Author(s): OLIVEIRA, A. H.; SOUZA, S. O. de; GOTTSCHALK, L. M. F.; TONON, R. V.; CABRAL, L. M. C.; CASTRO, R. J. S. de Repository: BDPA Publication year: 2019
Lipase production by Aspergillus niger 11T53A14 in wheat bran using experimental design methodology. Author(s): SANTOS, R. R. dos; MURUCI, L. N. M.; DAMASO, M. C. T.; SILVA, J. P. L. da; SANTOS, L. O. Lipases have various industrial applications and their production by filamentous fungi in solid state fermentation (SSF) process is of interest. In this work the lipase enzyme production by the mutant... ... Repository: BDPA Publication year: 2014
Flow injection system for hydrolysable tannin determination. Author(s): BOSSU, C. L.; FERREIRA, E. C.; CHAVES, F. S.; MENEZES, E. A.; NOGUEIRA, A. R. de A. A flow injection system was proposed to evaluate tIle transient product of a colorimetric reaction between hydrolysable tannin and potassium iodate (KIO3) solution. The system optimization was accompl... ... Repository: BDPA Publication year: 2006
