In this paper, we investigated the corrected plasmon dispersion relation for graphene in presence of a constant magnetic field which it includes a quantum term arising from the collective electron density wave interference effects. By using quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, the longitudinal plasmons ar...

We challenge the assumption that within-team variability in team efficacy is simply a methodological concern and statistical prerequisite. We do so by developing a theoretical model and research agenda for the study of dispersion in team efficacy. We construct a taxonomy that distinguishes four distinct forms of dispersion in team efficacy, discuss the antecedents to these forms of dispersion, ...

A method based on a statistical approach of estimating uncertainty in simulating the transport and dispersion of atmospheric pollutants is developed using observations and modeling results from a tracer experiment in the complex terrain of the southwestern USA. The method takes into account the compensating nature of the error components by representing all terms, except dispersion error and va...

Nowadays, utilisation of Nano-materials as one of the most recent methods of bitumen modification has attracted attention of many researchers. However, not enough research has been pursued on their mixing with bitumen, because of their dimensions and specific properties. In this study, the carbon Nano-tubes were mixed with bitumen using different mixers and some images were recorded employing a...
