  1. 1. Traceability in continuous processes : applied to ore refinement processes

    Författare :Björn Kvarnström; Josse De Baerdemaeker; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Sammanfattning : Introduction and purpose: Traceability is central for the identification of the root cause(s) behind a product deviation and thus to achieve a product and process quality that is both high and even. Continuous processes contain several characteristics complicating traceability which are not usually discussed in the scientific literature. LÄS MER

  3. 2. Traceability methods for continuous processes

    Författare :Björn Kvarnström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Sammanfattning : The subject of this thesis is traceability in continuous processes, i.e. the ability to trace products or batches through a certain process. Examples of the benefits from traceability are that it minimises the extent to which products are affected by product recalls and assures lot uniformity in production. LÄS MER

  4. 3. Plant-availability of phosphorus removed from wastewater by different processes

    Författare :Elisabeth Kvarnström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : The objective of this thesis was to investigate the plant-availability of P removed from wastewater by different processes, with focus on agronomic aspects. Short-term P availability was assessed by greenhouse studies, utilizing four different filter substrates and a sludge-recovered iron phosphate. LÄS MER

  7. 5. Pathophysiological mechanisms and clinical manifestations in primary Sjögren’s syndrome and Systemic lupus erythematosus (SLE)

    Författare :Marika Kvarnström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Primary Sjögren’s syndrome (pSS) is a systemic inflammatory autoimmune condition. The etiology of pSS is mainly unknown, but it has been suggested that environmental factors trigger an immune response in genetically susceptible individuals. LÄS MER
