We study the technological pre-conditions for a cost-minimizing choice of technique in the presence of government emission targets on by-products of production. Whether a by-product is a desirable commodity or an undesirable pollutant is determined endogeneously as part of the price-quantity equilibrium solution. Non-trivial counterexamples highlight the potential risk of over-ambitious polluti...

The theory of plasma emission and of electron cyclotron maser emission, and their applications to solar radio bursts and to Jupiter’s DAM and the Earth’s AKR are reviewed, emphasizing the early literature and problems that remain unresolved. It is pointed out that there are quantitative measures of coherence in radio astronomy that have yet to be explored either observationally or theoretically.

A simple and rapid method for the determination of 137Ba isotope abundances in water samples by inductively coupled plasma-optical emission spectrometry (ICP-OES) coupled with least-squares support vector machine regression (LS-SVM) is reported. By evaluation of emission lines of barium, it was found that the emission line at 493.408 nm provides the best results for the determination...

unlike other studies in which the autours have focused on testing the existence of an environmental kuznets curve, in this study, causality relationship between the energy consumption (oil equivalent), carbon emissions, gross domestic production, total labor force and fixed capital formation is investigated during 1960 to 2007 in iran. following an examination of stationary tests for all the va...
