Techniques are disclosed that enable an application to prioritize its traffic in an application-specific manner, such that traffic which is most important to this application can be prioritized over traffic that is less important to this application, where this prioritization information is reflected in differential treatment of the traffic within the network. The ferroelectric film includes a first ferroelectric film part having a first crystal system and formed along at least one interface with at least one of the lower electrode and the upper electrode and a second ferroelectric film part having a second crystal system that is different from the first crystal system. The openings for admitting flue gas to the convection sections can be at the top or the bottom of the heating section. An internally threaded bore in the keeper has a longitudinal axis. 1 wt % of bactericide into 50-90 wt % of vegetable oil and then mixing the obtained mixture to be homogeneous for use as dispersant, adding 2-25 wt % of separant into 10-40% of extra-high-molecular \u03b1-olefin-styrene polymer based drag reduction polymer and crushing them into powders at a temperature of lower than \u221290\xb0 C. The method uses finishing control subsystem having a multiplicity of operative process sensors along with tracked information to improve in situ control of finishing.
