The way to lower the recurrence and complication rates is to use an adjuvant procedure such as chemical or physical resection (phenol, hydrogen peroxide, liquid nitrogen or argon beam) [ 16, 24], which results in a reduced recurrence rate by broadening the zone of tissue necrosis.
When the first bandgap is characterized by the negative EMD, the bandgap maximization can be formulated efficiently as a topology optimization problem to broaden the frequency zone of the negative EMD values.
However, it should be noted that the efficiency roll-off problem can occur at the NPB/Bepp2 interface, which may be alleviated if bipolar blue emitters are used because bipolar materials can broaden the excitation zone.
It is found that, the effects of NTC on hydrodynamic quantities are to lower the von-Neumann peaks of density, pressure, and velocity, to broaden the reaction zone, and to subdue the chemical reaction.
Experimental results revealed BCzVBi doped TcTa film functions as predominant light-emitting layer, while BCzVBi doped 26DCzPPy film functions as supplementary light-emitting layer, which helps to broaden the recombination zone, improve the trapping of carriers and balance the distribution of holes and electrons on emitter molecules.
For that reason there was no reason to broaden the evacuation zone which currently extends about 7.5 kilometres around the crater.
This implies that turbulence does not broaden the CH reaction zone, and that flamelet concepts are justified in modeling the reaction zone associated with fuel decomposition.
Furthermore, the double light-emitting layers with TcTa (4,4′,4″-tris(carbazol-9-yl triphenylamine) carbazol-9-yl triphenylaminebazol-9-yl)phenyl)pyridine) hosts broaden the excarbazol-9-yl triphenylaminepress efficiency roll-off.
In addition, the stepwise distribution in energy levels of host materials is instrumental in broadening the recombination zone, thus delaying the roll-off of EL efficiency.
He had kind words for President George W. Bush, saying he hoped to work with him to create a hemisphere-wide free-trade zone and broaden the Plan Colombia anti-narcotics program across the Andean region with economic projects appropriate for Peru.
