The oxidation process occurring until the time associated to derivate peak is considered the induction period
, and the biodiesel is already considerably no oxidized.
In this regime the samples experience a little increase in birefringence for a very short time after the induction period
then a relaxation during the rest of the annealing process.
The vitamin C content found in calli is high during the calli induction period
when low concentrations of Picloram/Kinetin are used.
To estimate the kinematic viscosity changes that occur in this stage, the assumption can be made that following the end of the induction period
a complex oil decomposition process occurs and the formation of new compounds begins.
Comparative cement paste deflocculant studies show (Hommer, Wutz 2005), that suspension without deflocculant hy-dration induction period
lasts about 30 minutes (later to begin a massive hydrate deposition), and the suspensions deflocculant induction period
lasts about 2-3 hours, depending on the side chain length.
On the other hand, at the end of the induction period
electron microscopy evidenced the presence of a great number of proembryos in the callus surface, which were formed by a small suspensor and embryogenic pole that was composed by no more than two cells.
Hence, Fatty acid profile and quality factors such as peroxide value, free fatty acids and iodine value and induction period
before and after storage of samples at 25 and 45[degrees]C for 20 and 60 days in presence or absence of PET pieces in three types of common oils from Iran's market were investigated.
The valve timing of the engine used which shows a valve overlap (Scavenge period of 90%) where the exhaust valve closes at 4.50Crank angle after TDC thus leaving an effective induction period
of (180+35.5+4.5)-9 = 220.
Therefore, determination and comparison of the substantial initiation parameters (ignition and flash ignition temperature, ignition and flash ignition induction period
and critical heat flux) enables us to make a relative comparison of materials or products from the point of fire dynamics.
The study found no change in rates from 1998-2003, the period when possible associations between cell phone use and cancer risk would likely be apparent, assuming an induction period
of 5-10 years.
During the induction period
(days 1 to 5), half of the forage was given in the morning (at 8:30 am) and the other half in the afternoon (at 3:00 pm), while the mixed feed was all given at noon.
After an induction period
, crosslinking began, which resulted in an increase in damping (the slope of the line gives an estimate of the relative rate of cure).
