Abstract. Estimating the impact of ship emissions on local air quality is a topic high relevance, especially in large harbor cities. For chemistry-transport modeling studies, initial plume rise and dispersion play crucial role for distribution pollutants into vertical model layers. This study aims at parameterizing downward near field prototype cruise ship, depending several meteorological tech...

The Stolt migration extension to a varying velocity case (Stolt stretch) implies describing a vertical heterogeneity by a constant parameter (W ). This paper exploits the connection between modified dispersion relations and traveltime approximations to derive an explicit expression for W . The expression provides theoretically the highest possible accuracy within the Stolt stretch framework. Ap...

The role of coherent population oscillations is evidenced in the noise spectrum of an ultralow noise laser. This effect is isolated in the intensity noise spectrum of an optimized single-frequency vertical external cavity surface-emitting laser. The coherent population oscillations induced by the lasing mode manifest themselves through their associated dispersion that leads to slow light effect...

Laminar miscible displacement flows in narrow, vertical, eccentric annuli show a wide range of interesting physical phenomena, e.g. static layers and channels, dispersive spikes/fronts various instabilities. These are relevance to the primary cementing wells, where gas leakage greenhouse emissions can result from ineffective cementing. The current popular way model this process is via Hele-Shaw...

today, the cement industry is one of the major air polluting industries in the world. hence, in this study, owing to the importance and role of contaminants from the plant, an appraisal of the emission contributions in addition to other factors have been discussed. there are several reasons behind the importance of modeling air pollutants. first, the assessment of standards for air pollution, a...

This study introduces vertical pay dispersion, a prevailing equity issue in discussions of organizations and society, to public management research. Bridging tournament theory with the publicness debate, analyses role dimensions —ownership, funding, control— for manager-to-worker ratios state-owned enterprises (SOEs). The results show that, unique five-year data set, ownership partly affects ef...
