  2. 1. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction

    Author : Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Andrew Barnes; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extractive waste characterisation; drainage water; ARD; NRD; ABA test; NAG test; SEM; Applied Geochemistry; Tillämpad geokemi;

    Abstract : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. READ MORE

  4. 2. Potential of fly ashes for neutralisation of acid mine drainage from coal mine waste rock

    Author : Asif Qureshi; Josef Mácsik; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Many countries around the world use coal as fuel for the purpose of power generation. The extraction of coal produces large volumes of waste rock (WR) that are sometimes sulphide rich (principally containing iron sulphides such as pyrite (FeS2) and pyrrhotite (Fe1-xS)), with varying quantities of trace elements such as As, Si, Cu, Zn, Ni, Co, Mo and Cr etc).

  5. 3. Influenza virus : protection and adaptation

    Author : Camilla Maria Mittelholzer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Human influenza A virus; DNA vaccine; Neutralisation test; Antigen drift;

    Abstract : Influenza is an acute respiratory disease caused by influenza type A and B viruses. Human influenza viruses may infect up to 15% of the total population during the seasonal epidemics, causing many cases of severe illness. Each year, approximately 350 million doses of influenza vaccine are produced for protection of those at risk of severe disease. READ MORE

  6. 4. Genetic and antigenic characterisation of Puumala virus in voles and man

    Author : Jan Hörling; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The present study has focused on the genetic and antigenic characteristics of Puumala (PUU) virus, the causative agent of nephropathia epidemica (NE). An assay for detection of neutralising antibodies to PUU virus was developed. READ MORE

  7. 5. Cytokine responses in metal-induced allergic contact dermatitis : Relationship to in vivo responses and implication for in vitro diagnosis

    Author : Jacob Minang; Marita Troye-Blomberg; Niklas Ahlborg; Rik Scheper; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metal allergy; Contact dermatitis; cytokines; ELISA; ELISpot; Flow cytometry; Immunology; Immunologi;

    Abstract : Transition metals such as nickel (Ni), cobalt (Co), palladium (Pd), chromium (Cr) and gold (Au) are widely used as alloys in jewelry and biomaterials such as orthodontic and orthopaedic appliances. These metals also cause cell-mediated allergic contact dermatitis (ACD) reactions in a significant proportion of the population upon prolonged direct exposure. READ MORE
