    Sammanfattning : It is often said, among practicians and theorists, that doing business is about taking risks. Thisthesis is focused on the relationship between doing business, and thereby earning a return, andthe inherent risk taking. LÄS MER

  4. 3. Cementation of cyanidation tailings – effects on the release of As, Cu, Ni and Zn

    Författare :Roger Hamberg; Christian Maurice; Lena Alakangas; Mamadou Fall; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geochemistry; Tillämpad geokemi;

    Sammanfattning : Knowledge about mineralogy and chemical composition in sulfidic tailings is essential to predict how tailings management may affect the future leachate quality. At a gold mine in the north of Sweden, gold was extracted from inclusions in arsenopyrite and pyrrhotite by the use of cyanide. LÄS MER

  5. 4. Characterization and solidification of arsenic-rich cyanided tailings

    Författare :Roger Hamberg; Lena Sultan; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Information on the occurrence of As species and iron sulphide minerals in tailings is essential for predicting therelease of As over extended period of time. Tailings originating from a goldmine in northern Sweden with low content of trace elements except for As were used for this purpose. The dominating sulphides were pyrrhotite and arsenopyrite.

  7. 5. Enzyme selectivity as a tool in analytical chemistry

    Författare :Anders Hamberg; Karl Hult; Harry Brumer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; substrate specificity; competing substrates; enantiomeric excess analysis; library screening; ladder sequencing; carboxypeptidase Y; 2-pyridylmethylamine; MALDI; Candia antarctica lipase B; pig liver esterase; horse liver alcohol dehydrogenase; acylated cyanohydrins; Biochemistry; Biokemi;

    Sammanfattning : Enzymes are useful tools as specific analytical reagents. Two different analysis methods were developed for use in the separate fields of protein science and organic synthesis. Both methods rely on the substrate specificity of enzymes. Enzyme catalysis and substrate specificity is described and put in context with each of the two developed methods. LÄS MER
