Thermogravimetric analysis show that the more thermally stable copolymers are random copoly ester-ether)s formed at higher reacopoly ester-ether
Using higher reaction time of 24 h, the average diameter of the nanoparticles increased from 60 to 80 nm (Fig. 1c).
But at high reaction time, increasing the percentage of 10 kDa mPEG in the mixture of mPEGs (5 and 10 kDa) from 0 to 100 caused an initial decrease in IL-2 secretion with a minimum point occurring at 63.68%.
On the other hand, high cost, unavailability, low activity and high reaction time of enzymes limit the use in industrial scale glycerolysis reactions for the production of food-based emulsifiers (i.e. monoglycerides).
The ratio of cycle-containing molecules reached 50% at high reaction time for the polyester without core molecule, but was much lower for the polyesters containing a core molecule.
Higher reaction time variability or performance inconsistency is also thought to indicate fluctuations or lapses in attention (Van de Molen 1996).
It is interesting to note that participants exhibited an overall worse performance (lower accuracy, higher reaction time and higher Weber fraction) in the temporal discrimination task.
The most consistent result was the association between the DRD4 gene and high reaction time variability, whereas many findings of association with other genes need replication.
Low P300 amplitudes and high reaction time variability point to decreases in auditory target processing in subjects with current nicotine use.
