21. Biomass, community structure and phosphorus uptake of ectomycorrhizal fungi in response to phosphorus limitation and nitrogen deposition
Abstract : High levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching. READ MORE

22. Modulating the anion ordering in apatites
Abstract : Hydroxyapatite constitutes the main inorganic part of the skeleton, and since the beginning of the seventies, synthetic apatite has been used in implants. The physical properties of this crystalline material are directly dependent on its atomic arrangement. If a better understanding of apatite chemistry is sought, important for e.g. READ MORE

23. The Growth of External Ectomycorrhizal Mycelia in the Field in Relation to Host Nutrient Status and Local Addition of Mineral Sources
Abstract : A method based on ingrowth mesh bags was developed to study the production of EMM. These bags were made of nylon mesh with a mesh size of 50 mu-m, which allows colonisation by fungal mycelia but excludes the tree roots. READ MORE

24. Genesis and Diagenesis of the Phosphatic Hardground of the Holm Dal Formation (Late Middle Cambrian), North Greenland
Abstract : The phosphatic hardground of the Holm Dal Formation (late Middle Cambrian) of North Greenland is composed of two parts: one basal with abundant allochthonous material and an upper part without an allochthonous component. It was formed by release of phosphate, by bacterial degradation, from organic matter which accumulated in lime mudstones on which the hardground developed. READ MORE

25. Biomimetic Deposition of Hydroxyapatite on Titanium Implant Materials
Abstract : The clinical success of a bone-anchored implant is controlled by many factors such as implant shape, chemical composition, mechanical and surface properties. The surface properties (e.g. READ MORE
