It was assumed that the PI point is the point at which the volumes of both phases is equal [35] The value of conversion at which PI occurs in the simulated conditions is found to be approximately 12%, within the range reported in the literature [8].
n,PS] at the PI point is very slightly dependent on initiator concentration.
As regards grafting efficiencies at the PI point, it can be seen that cyclic initiators provide lower values than the linear initiator, indicating a lower selectivity toward grafting reactions with this type of initiators, as previously reported [22].
If the molecular structure at the PI point was correlated to the final product morphologies, this model could be used to find the optimum conditions of the prepolymerization stage (TPP, [[[I.
Moreover, using molecular weight data, dimension of the phases, viscosity of the reaction blend, and the relaxation time in models reported in the literature (18), (19), it was possible to obtain relevant information about the interfacial tension in the PI point.
wPS] is the average molecular weight of the PS, which is considered as the continuous phase at the PI point.
With the determination of the PI point through different characterization techniques, the [PS.
Between July and August, the skyscaper leapfrogged over 15 other towers to claim the top spot with an increase of 83 PI points.
The biggest jump for the tower came in July when it reached the second spot and pocketed 55 PI points, said its developer Tameer, citing the Bayut data.
Abu Dhabi has continued to lose PI points as well as its unique visitors which was 27,143 in July but dropped to 21,139 in August.
But Pi points out that scientists are hardly always objective: in their time they dismissed visionaries like Copernicus and Darwin.
OSIsoft protects existing investments that leverage PI Points and the PI Module Database (MDB), by allowing the user to migrate from MDB to AF without impacting existing deployments such as PI ACE calculations or other MDB-based applications.
