Sorption efficiency arithmetical mean was calculated after different contact time with zeolite samples, to evaluate which contact time is most effective on sorption efficiency.
This efficiency can be enhanced by increasing contact time as in Zhang et al.
However, scientific advances have been made to the formulation of hydrogen peroxide products to associated weaknesses such as instability, limited antimicrobial efficacy and long surface contact times.
Table 4 summarizes the relationships between the shuttle run cutting time and trunk inclination angle and between the ground contact time and trunk inclination angle, respectively.
Contact time is defined as the contact time of oil with displacing fluid under reservoir conditions (pressure and temperature).
The reason that we can not get rather high acrylic acid yield with long contact time at elevated reaction temperature can be due to the occurrence of side reactions from lactic acid.
The ratio between the relative intensities of the resonances at -84 and -98 ppm for short contact time is about 0.

When identifying operations where a tool may run better without coolant, look for two main criteria: 1) short contact time in cut, or 2) thermal cycling of the cutting edge such as indexable milling tools or interrupted cuts in turning.
To address the barrier of lack of time, each of the four classes lasted one hour and the screening and individual consultation required approximately an hour and a half, therefore the total contact time commitment for the entire program was five and a half hours.
DHA removal was affected by tailoring the length of the cation chain (optimum C15 or higher), the pH (improved removal at lower pH), the treatment time (minimum contact time of 3 min), and the mineral dose.
