  1. 1. Large and rare : An extreme values approach to estimating the distribution of large defects in high-performance steels

    Författare :Jens Ekengren; Jens Bergström; Christer Burman; Thomas Svensson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-metallic inclusions; Tool steel; Extreme value statistics; Distribution of defects; Generalized extreme values; Materialteknik; Materials Engineering;

    Sammanfattning : The presence of different types of defects is an important reality for manufacturers and users of engineering materials. Generally, the defects are either considered to be the unwanted products of impurities in the raw materials or to have been introduced during the manufacturing process. LÄS MER

  2. 2. Acoustofluidic rare cell sample preparation

    Författare :Maria Antfolk; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Acoustofluidics utilizes a combination of acoustics, in the form of ultrasound, and microfluidics to manipulate cells and particles. This has proven to be a versatile method that is gentle to the cells. In this thesis acoustofluidics has been used for processing rare cells in continuous flow. LÄS MER

  3. 3. Rare complications in cancer surgery

    Författare :Johan Björklund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Curative cancer surgery aims to reduce mortality and morbidity related symptoms caused by the cancer. The surgery is often done at a time when the patient is presenting lesser or no symptoms and at a time when the cancer is not presenting an immediate threat to the patient’s life. LÄS MER

  4. 4. Modeling and Optimization of Rare Earth Element Chromatography

    Författare :Mark Max-Hansen; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rare Earth Elements; Chromatography; Modeling; Optimization;

    Sammanfattning : The Rare Earth Elements are a group of metals, that are of growing technical and economical importance. Current separation techniques can be detrimental to the environment, and a clean technology for separation has been devised, based on analytical chromatography of the REEs. LÄS MER

  5. 5. Heredity in Parkinson's disease. From rare mutations to common genetic risk factors

    Författare :Andreas Puschmann; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson s disease; parkinsonism; genetics; alpha-synuclein; SNCA duplicaion; SNCA triplication; LRRK2; PARKIN; PARK2; VPS35; EIF4G1; rare variants; digenic inheritance; heritability;

    Sammanfattning : This study investigated genetic causes of Parkinson's disease (PD) and parkinsonism in southern Sweden. The extensive Lister Family with parkinsonism caused by duplications and triplications of the gene for alpha-synuclein (SNCA) was studied. Clinical, genetic and genealogical data were compiled and evaluated. LÄS MER
