Several strategies were evaluated, including the use of those enzymes alone, in a mixture and under different conditions of temperature, time and substrate concentration.
Different conditions of extraction time (t), temperature (T), ethanol concentration (Et) and solid/liquid ratio (S/L) were combined in a circumscribed central composite design and optimized by response surface methodology.
Specifically, plasma oxidation was carried out under three different conditions of power and/or time of exposure.
SE was carried out in a high-pressure steam reactor under different conditions of temperature (180 °C 200 °C), time (5 min–10 min) and acid concentration (1 100 H2SO4 - 3 100 H2SO4 (on mass of dry wood)) according to a factorial design.
The adsorptive behaviors of 4NA and 2A3NP by γ-Al2O3-Silane-Cl from aqueous solutions were investigated using the batch technique and optimized in presence of different conditions of initial pH, contact time, nanosorbent dosage, initial concentration of nitro compounds and coexisting metal salts.
Figure 2 shows the absorption spectra of PTHA or oligo-THA obtained by polymerizing surface-bound THA on TiO2 electrodes at different conditions of polymerization temperature and time.
Open image in new window Fig. 2 Cavitation yield obtained under different conditions of sonication frequency and time using 0.1 wt% KI solution Open image in new window Fig. 3 Cavitation yield obtained under different conditions of sonication frequency and time using 1.0 wt% KI solution.
The hope was to catch fish and pastry crossing a finish line, in different conditions of doneness, at the same time: the pastry brown, crusty, crunchy, hot; the fish rosy-red, warm.
To ascertain the composition and the factors affecting the viscosity of RA, some samples were prepared in the case of different conditions of mixing temperature and processing time for different rubber dosage and rubber size.
The adsorption performance of MMT@C nanocomposites were systematically investigated and discussed using methylene blue (MB) as a model pollutant in aqueous solution by a batch technique under different conditions of initial dye concentration, contact time and solution pH.
The experiments were planned as per L27 orthogonal array to minimize the experiments, each experiment was performed under different conditions of pulse duration, pulse off time, servo voltage, flushing pressure and wire speed.
