    Environmental tax reform in the Czech Republic

    Get PDF
    About the Czech environmental tax reform, it can be said that its concept is not very well known even to its principal stakeholders. The reason is the little promotion: the absence of explanatory campaigns. The support to dealing only with existing local environmental problems and the opposition to introducing an environmental tax reform aimed at combating climate change connected with consistent revenue recycling points at a certain short-sightedness, cause probably largely by the lack of awareness of the risks as well as advantages of the environmental tax reform approach where the revenues are fully recycled. It is here that foreign experience in terms of evaluating the environmental tax reform impacts on economies and environment may play a key role in the promotion and implementation of the Czech environmental tax reform. And also, further increases of the CO2 tax rates in the Czech Republic should be preceded by a quantification of its impacts on the Czech economy using e.g. CGE or the E3ME model, or other techniques.

    Extension of the Schiff theorem to ions and molecules

    Full text link
    According to the Schiff theorem the nuclear electric dipole moment (EDM) is screened in neutral atoms. In ions this screening is incomplete. We extend a derivation of the Schiff theorem to ions and molecules. The finite nuclear size effects are considered including Z^2 alpha^2 corrections to the nuclear Schiff moment which are significant in all atoms and molecules of experimental interest. We show that in majority of ionized atoms the nuclear EDM contribution to the atomic EDM dominates while in molecules the contribution of the Schiff moment dominates. We also consider the screening of electron EDM in ions

    Temperature-dependent Raman scattering of DyScO3 and GdScO3 single crystals

    Full text link
    We report a temperature-dependent Raman scattering investigation of DyScO3 and GdScO3 single crystals from room temperature up to 1200 {\deg}C. With increasing temperature, all modes decrease monotonously in wavenumber without anomaly, which attests the absence of a structural phase transition. The high temperature spectral signature and extrapolation of band positions to higher temperatures suggest a decreasing orthorhombic distortion towards the ideal cubic structure. Our study indicates that this orthorhombic-to-cubic phase transition is close to or higher than the melting point of both rare-earth scandates (\approx 2100 {\deg}C), which might exclude the possibility of the experimental observation of such a phase transition before melting. The temperature-dependent shift of Raman phonons is also discussed in the context of thermal expansion

The article continues a series of topics in depth by the author, and concludes by reminding us that the terrifying impact of modern Western world, does not cancel the truth that human history has been remarkably pluralistic, and there are no general laws of society, but only cultural agreements
