Local emissions term effects

The results of tests conducted using the pressure-atomizing nozzle with emulsified fuels are presented in Figures 11 and 12. They are expressed in terms of the effect of increased water addition on combustion eflBciency and pollutant emission rates. The data in Figure 11 indicate that combustion eflBciency increased with increased water addition, reaching a maximum at approximately 5% water added, and thereafter decreased, perhaps as a result of local quenching in the primary zone caused by water addition. A 15% increase in eflBciency relative to that attained with neat fuel was obtained using a 5% emulsion. The measured eflBciency for operation with No. 2 fuel oil is shown for comparison, and differences... 

A brief review and reassessment of data on the photophysics of benzene has been presented by Pereira. Evidence for the l E2g valence state has been obtained by u.v. two-photon spectroscopy.Slow electron impact excites fluorescence in thin films of benzene at 77 K as well as emission from isomers." The fluorescence yields and quenching by chloroform of alkyl-benzenes and 1-methylnaphthalene after excitation into Si, Sz, and S3 states and after photoionization have been measured. The channel-three process has been reconsidered in terms of the effects of local modes and Morse oscillator potentials. Excited-state dipole moments of some monosubstituted benzenes have been estimated from solvent effects on electronic absorption spectra, Structural imperfections influence the photochemistry of durene in crystals at low temperatures. Relaxation time studies on excited oxido-substituted p-oligophenylenes have been made by fluorescence depolarization... 

The improved forecast techniques can be used in two ways. Firstly, it can be the short-term episode forecasts for the next few days. Secondly, it is an integrated modelling system for long-term air quality management to predict future episodic pollution levels, taking into account estimated trends in local traffic and other emissions. In both ways the modelling system can be employed to evaluate alternative scenarios and to develop efficient strategies to reduce emissions, pollution levels, and PE to prevent health consequences in a cost-effective way. 

EM was quite extensively and successfully applied to model optical spectra of molecular crystals and aggregates. Extensions were discussed [18] to account for disorder, whose effects are particularly important in aggregates, and to include the coupling between electronic degrees of freedom and molecular vibrations [48], needed to properly describe the absorption and emission bandshapes. However, as it was already recognized in original papers [7, 46], other terms enter the excitonic Hamiltonian. Electrostatic interactions between local excitations can in fact be introduced as ...
