The conditions for maximum Co precipitation were then chosen to study the effect of various parameters such as time and temperature of storage and initial cobalt concentration on extent of precipitation.
The effect of operational conditions such as the initial p-nitrophenol concentration, pH and catalyst concentration on the extent of degradation has been investigated using sonophotocatalysis.
The extent of control of enzyme concentration on the flux is expressed as the flux control coefficient and is estimated directly by experiments and by modeling techniques.
A sensitivity analysis was conducted to determine the effect of flue gas temperature, particle diameter, and SO2 concentration on the extent of sulfation.
No significant influence of homocysteine concentration on the extent of craving was found for either group with the use of the Spearman correlation (day 0: group A, r = −.076, P = .601; group B, r = .120, P = .148) and logistic regression analysis.
The results showed a statistically significant effect of pH and pulp density – and to a lesser extent temperature and initial Fe(II) concentration – on the rate of bioleaching of Zn.
The concentration on education was responsible, to a large extent, for the nature and speed of Japan's economic and social progress.
The upper time limit of short-time permeation data suitable for analysis with the time lag method was determined based on the extent of concentration variations across the membrane, and the onset time point of the long-time permeation data for analysis with the mass balance method was determined based on the time lag of the system.
The relative ratios among products and selectivity were found to be highly dependent on the nature of the electrolyte used, and to a lesser extent on substrate concentration.
A reciprocal dilution experiment was performed to determine the extent to which on-slide concentrations of an oligonucleotide were mimics of the effects of variable concentrations of the solution-phase cRNA partner in bi-molecular hybridization reactions and therefore suitable for normalizing experimental variations in cRNA hybridization.
The time that an antiseptic takes to act depends to some extent on its concentration, but the speed at which different antiseptics kill bacteria varies considerably; thus, the halogens (e.g., iodine and chlorine salts) act quickly, whereas mercurials, compounds of heavy metals, and dyes act slowly.
