The initiation step
starts when photoinitiator molecules absorb photons to form photoinitiator free radicals, I*.
The objectives of this project are to (a) develop a radiation intensity model to derive the intensity field characteristics in absorbing, reacting, and scattering reaction media in which the rate of the reaction initiation step
is expressed as a function of the local volumetric rate of energy absorption (LVREA); (b) develop a model for inactivation of microbes in a filter fiber media using mathematical and experimental data.
They are believed to be involved in the initiation step
of translation at high temperature and possibly a molecular chaperone.
After the initiation step
is complete, and individuals begin to react to common, everyday chemicals and substances, these reactions are termed "triggering.
v-Ha-ras transgene abrogates the initiation step
in mouse skin tumorigenesis: effects of phorbol esters and retinoic acid.
The number of monomer/oligomer molecules forming a polymer in initiation step
is negligible in the beginning.
In breast cancer, the initiation step
appears to occur sometime during puberty, during the development of the mammary gland, and does not appear to be related to diet.
As this coloration starts from the beginning of the polymerization, it can be related to a change in the chemical structure of DMAP in the initiation step
Solution pH influences the process primarily through the initiation step
The above results indicate that the sharper the notch the less effect the thermal history has on the fracture energy, or in other words, the crack initiation step
is more sensitive to the thermal treatment used in the foaming procedure than the crack propagation step.
Abraham Awolich, a coordinator at the steering committee secretariat said the initiation steps
would take more than a month.
