While the sources of releasing dioxins have received much attention, the health risks of incinerators are studied considerably more than those of other sources, such as metallurgical industry. Furthermore, risk assessments focus primarily on the effects of single sources; few have addressed the aggregate risks from multiple sources in a region. When many sources of dioxins exist in an area, suc...

Source separation, recycling, combustion, and bene­ ficial use of ash residues are important components of plans for management of household and commercial wastes in order to minimize the cost and risks of landfilling. Municipal incinerators, originally built to avoid unsanitary landfills, are now becoming efficiently operated power plants. However, in order to obtain permits to build and opera...

This paper presents experimental investigations of the in situ diagnosis of the alkali metals in the municipal solid waste (MSW) flame of an industrial grade incinerator using flame emission spectroscopy. The spectral radiation intensities of the MSW flame were obtained using a spectrometer. A linear polynomial fitting method is proposed to uncouple the continuous spectrum and the characteristi...

This paper analyses the problem of sub-national revenue mobilization in Peru and proposes several policy reforms to improve collection performance while maintaining a sound revenue structure. We analyze the current revenues of regional and municipal governments and identify the main priorities of reform. Among the most important problems are the acute inequalities and inefficiencies associated ...

WiFi offloading has been recently proposed as a cost-effective solution for coming up against the unprecedented increase in the mobile data traffic volume. However, apart from reducing the operational costs of a network operator, WiFi offloading can be also promoted as an alternative low-cost access service for users with low willingness-to-pay. In this paper, we consider a monopolistic scenari...
