In this formula, B was Na2S2O3 consumption of control sample; A was Na2S2O3 consumption of control sample; N was equivalent concentration of Na2S2O3; 0.51 was a constant meaning that 1 mg equivalent Na2S2O3 equal to 0.51 mg equivalent free galacturonic acid; S was the total reaction liquid volume for keeping warm; E was used enzyme volume; t was the holding time; M was absorbing reaction quantity.
Compared with the previous simulation without consideration of coke distribution, this approach increases the computational time by a factor of 36% and shows no influence on hydrodynamic predictions, but the reaction quantities such as methanol conversion, mass fractions of gaseous products and selectivity of light olefins, are better predicted.
Moreover, according to these two reactions, the quantity of bridgehead C atoms should be increased simultaneously, which is also verified by the AD profile in Fig. 4.
Predictor variables included in a generalized linear regression were number of sequences, number of attempted PCR reactions, DNA quantity, and age of samples.
In order to establish the most appropriate conditions for the reaction the quantity of sample template was tested.
In order to determine the limit of background human DNA tolerated by the RPA and PCR reactions, varying quantities of human genomic DNA (100, 200 and 400 ng) were added to reactions containing 50, 20 or 4 S.
For the binding reactions, equal quantities of nuclear extracts (1 4 μg) were incubated with 10 000 c.p.m. of end-labeled NF-κB oligonucleotide and 1 μg of poly dI dC (GE Health Care, Buckinghamshire, UK) in the binding buffer (20 mm Hepes, pH 7.6, 20% (w/v) glycerol, 100 mm NaCl, 10 mm MgCl2, 0.2 mm EDTA, 1% (w/v) Triton X-100, 1 mm dithiothreitol).
The catalyst quantity, reaction temperature and reaction time were optimized to apply them in the conditions of a reactive extrusion process with a co-rotating twin screw extruder.
The efficiency of the dehydrogenation reactions and the quantity of products depend on the catalyst used.
Furthermore, the ways for conducting inorganic precipitation reactions and the quantity of Ag deposited also affect the surface morphologies of the composite microspheres [ 29].
