Kluyveromyces lactis β-galactosidase crystallization using full-factorial experimental design

Journal of Molecular Catalysis B: Enzymatic, 2008
Kluyveromyces lactis β-galactosidase is an enzyme with numerous applications in the environmental, food and biotechnological industries. Despite of its biotechnological interest, its three-dimensional structure has not yet been determined. The growth of suitable crystals is an essential step in the structure determination of a protein by X-ray ...

Full Factorial Design Approach to Hg(II) Adsorption onto Hydrogels

Arabian Journal for Science and Engineering, 2014
A 24 factorial design was used to evaluate the quantitative adsorption of Hg(II) ions in an aqueous solution onto radiation crosslinked poly(acrylic acid/acrylamide) hydrogels. The influence on the binding ratio (r) of variables such as pH, temperature, initial concentration of solution, and material was analyzed statistically using a suggested ...

Full Factorial Optimization of Concrete Mix Design for Hot Climates

Journal of Materials in Civil Engineering, 2001
This paper presents the results of a statistical analysis aimed to optimize a concrete mix design for hot climates. A full factorial experiment with 3 × 4 × 4 × 3 treatment combinations (432) samples) of 48 mixes at three levels of temperature was used. The influences of the water/cement ratio (0.4, 0.5, and 0.6), coarse aggregate/total aggregate ratio

Full Factorial Design to Study Material Parameters of Magnetorheological Fluid

Key Engineering Materials, 2013
This paper presents the effects of magnetorheological (MR) fluid parameters, bidisperse ratio, carrier fluid viscosity and particle volume fraction, on its mechanical behaviour using statistical investigation. Silicone oil-based MR fluid samples were compressed using universal testing machine (UTM) in a vertical direction.

Introduction to Full Factorial Designs with Two-Level Factors

2009
Factorial experiments with two-level factors are used widely because they are easy to design, efficient to run, straightforward to analyze, and full of information. This chapter illustrates these benefits. The standard regression models for summarizing data from full factorial experiments are introduced, and an example is given to illustrate the ...
