    Abstract : This dissertation aims to advance the current understanding of the general conditions affecting the likelihood of military conflicts and wars between states. To that end, the dissertation develops a Darwinian theory of international conflict. READ MORE

  6. 4. Molecular perspectives on goethite dissolution in the presence of oxalate and desferrioxamine-B

    Author : Anna A. Simanova; John Loring; Owen Duckworth; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : Iron, an essential nutrient, is primarily present in soils in the form of iron-bearing minerals characterized with low solubilities. Under iron deficient conditions, some plants and microorganisms exude a mixture of iron-complexing agents, including carboxylates and siderophores, that can cause minerals to dissolve and increase iron solubility.
