This paper presents a brief literature review concerning the costs and benefits of electric vehicles and hybrid electric vehicles, highlighting their advantages in terms of greenhouse gas emissions reductions. Even though electric and electro-hybrid vehicles must still overcome many cultural and...

The Southeastern Pará has been an area of extraordinary dynamics in the Brazilian Amazonia. There were allocated the great cattle ranching projects financed by SUDAM in the sixties and seventies, which confronted the moving frontiers of both peasants and gold miners. Main area of the Vale do...

This paper investigates if pollution permit markets are harmful for employment within a Wage Setting-Price Setting (WS-PS) model. The employment level is determined according to several financing unemployment benefits: a wage tax or the revenue of the pollution permit auction. We first show that...

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...

A discussão atual sobre a emissão de carbono associada ao uso agropecuário da terra em prejuízo de florestas se recente de uma visão sistêmica. Dado que os esquemas de compensação implicam em entrada e saída de recursos em contextos econômicos amplos e sistêmicos, é fundamental...

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...
