Sentence examples for concentration only about from inspiring English sources

However, for the 1 × 10-4 mol/L and MB concentration, only about 10% was degraded after 240 min. Therefore, it seems that the photodegradation efficiency of the MB photocatalyzed by the CNT-CdSe composite decreased as the original MB concentration increased.

At higher BSA concentrations the saturation kinetics indicated that the amount of solid curcuminoids available for solubilization in BSA was the limiting factor, although at a 1400 μM curcuminoid concentration only about 1.7% of the total added curcuminoids had actually been solubilized.

An unreported feature of this apparatus is that in rich concentrations only about half the dust injected is burned in the explosion, while the overpressures remain high.

Uranium is dissolved in seawater at very low concentrations, only about 3 parts per billion (3 micrograms/liter or 0.00000045 ounces per gallon).

However, at these concentrations only about 5% of the gntro-expressing cells survived.

And while CFC-11 concentrations in the atmosphere are decreasing overall, this study found the decrease to be slowing; CFC-11 concentrations decreased only about half as fast over the last three years as they did in the last decade.

In fact, Wood's metal concentration in the interior is only about 4%% under high pressures, which indicates that only a limited number of the interior pores are connected to the outside by a continuous pathway.

However, the data depicted in Figure 4 and corresponding reports for low doxorubicin doses [ 21] indicate that the drug export lowers the intracellular concentration only by a factor of about 2. This means that some other factors must be responsible for the MDR resistance that corresponds to additional 20-30 foldrugug concentration change.

A single, subcutaneous injection of 150 mg recombinant IL-1Ra in humans achieves a peak plasma concentration of only about 1.6 μg IL-1Ra/ml, and concentrations superior or equal to 1 μg IL-1Ra/ml exist only for about 14 hours.

Photo-DSC exotherm results for relatively thick films (∼150 μm) showed an increase in the polymerization reactivity (R) up to a concentration of only about 2 mol% N-aliphaticmaleimide. RTIR analysis was used to determine that the reactivity of a diacrylate thin film (∼10 μm) increased continually as the concentration of AcOEMI increased from 0.1 to 30 mol%.

Under the influence of micro wave energy high product yield was achieved in very short time and the required catalytic concentration was only about one tenth compared to that required to carry out standard MBH reaction.
