    Sammanfattning : 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. LÄS MER

  3. 2. The effect of forest nutrients status on ectomycorrhizal growth and community structure in response to minerals

    Författare :Christoffer Berner; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Ectomycorrhiza are a symbiosis between trees and soil inhabiting fungi. The fungal hyphae ensheath the fine roots creating a mantle and grow in between root cells to create the Hartig net, where the exchange of carbon and mineral nutrients occurs. The ectomycorrhizal fungus is dependent on the host tree to receive the carbon it needs to grow. LÄS MER

  4. 3. Mineralogical, chemical and textural properties of the Malmberget iron deposit : a process mineralogically characterisation

    Författare :Cecilia Lund; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : This thesis combine two different but closely connected disciplines in a mining process to each other, ore geology and process mineralogy by studying mineralogical-textural features of the ore and the ore concentrate in an apatite iron ore deposit in Malmberget, Sweden. Apatite iron ore deposits (Kiruna type) exist in a few places around the world and the two most important deposits are mined by LKAB at Kiruna and Malmberget. LÄS MER
