In the Eulerian approach the behavior of the atmospheric pollutants is described relative to a fixed coordinate system. Thus the pollutant concentration is a function depending on the system coordinates and must satisfy the material balance taken over a volume element. Expressed mathematically,...

In the current document we are referring to the existing data concerning the impact that benzene - which is one of the most important components of different types of fuels - has on Bucharest and on its inhabitants. We are also trying to present possible solutions to this serious problem which...

In the Lagrangian approach to the turbulent diffusion the species concentrations are described relative to the moving fluid. This approach is concerned with the behavior of the fluid particle existing in a carrying turbulent fluid. Lagrangian theory describes the statistics of the pollutant...

New tax rules with effect from 1 May 2009 with a series of changes on the tax deductibility of the value added acquisitions related to transport and fuel use. The measure is very obvious nature of politics in order to bring the state budget amounts as required under the current government crisis...
