   Abstract : The Causal Effect of Political Power on the Provision of Public Education: Evidence from a Weighted Voting SystemWe estimate how political power affects the provision of public education in local governments, using data from a nondemocratic society where voters received votes in proportion to their taxable income. This was the system used in Swedish local governments during the period 1862–1909. READ MORE

4. 2. Unraveling the importance of solid and adsorbed phase mercury speciation for methylmercury formation, evasion and bioaccumulation

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mercury; methylmercury; aquatic systems; estuary; Hg; MeHg; bioaccumulation; methylation; demethylation; evasion; sediment; water; terrestrial sources; atmospheric sources; climate change; eutrophication;

   Abstract : Monomethylmercury, MeHg, is formed under anoxic conditions in waters, sediments and soils and then bioaccumulated and biomagnified in aquatic food webs, negatively effecting both human and wildlife health. It is generally accepted that precipitation of mercury, Hg, and adsorption of Hg to e.g. READ MORE

   Abstract : Magnetic metamaterials consisting of arrays of densely packed, two-dimensional nanoscale magnetic islands have degrees of freedom on two separate length scales: inside the islands, and among them. These degrees of freedom can be tuned by e.g. size, shape, island separation and lattice geometry. READ MORE
