  1. 1. Ab initio modeling of xanthate adsorption on ZnS surfaces

    Författare :Pär Hellström; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Teknisk-vetenskapliga beräkningar;

    Sammanfattning : Modeling surface adsorption requires systems of hundreds of atoms. To model such systems at an ab initio level successfully, we need to avoid traditional quantum chemical methods. LÄS MER

  3. 2. Ab initio modelling of xanthates adsorbed on Ge and ZnS surfaces

    Författare :Pär Hellström; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Teknisk-vetenskapliga beräkningar;

    Sammanfattning : The motivation for this modelling work, in close collaboration with experimentalists, is to contribute to the understanding of xanthate adsorption on ZnS surfaces in the flotation process. Adsorption of xanthates on Ge surfaces is investigated, which also have been studied experimentally in the Agricola Research Centre. LÄS MER

  5. 4. Gut microbiota in colorectal cancer : The importance of Parvimonas micra

    Författare :Thyra Löwenmark; Richard Palmqvist; Sofia Edin; Pär Larsson; Michael Dahlberg; Per Hellström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; mucosal microbiota; Parvimonas micra; Fusobacterium nucleatum; immunity; survival; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Sammanfattning : Colorectal cancer (CRC) is a heterogenous disease consisting of multiple molecular subtypes, each of which has diverse treatment responses and prognoses. The importance of the gut microbiota in CRC development and progression has undergone increasing recognition in recent years, with a structural segregation in terms of microbial composition between CRC patients and healthy controls.

  7. 5. "VEM är jag?" : Det lyriska subjektet och dess förklädnader i Tomas Tranströmers författarskap

    Författare :Magdalena Slyk; Håkan Möller; Pär Hellström; Anders Cullhed; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; the lyrical subject; autobiography; memoirs; Tomas Tranströmer; Literature; Litteraturvetenskap; Literature; Litteraturvetenskap;

    Sammanfattning : The aim of this dissertation is to examine how the lyrical subject is presented in Tomas Tranströmer’s poetry and prose.  Crucial concepts such as the lyrical subject, autobiography, and the memoir are thoroughly discussed and defined based on modern research. The first chapter is devoted entirely to Tranströmer’s prose. LÄS MER
