  3. 2. Synaptic elimination and the complement system in Alzhaimer's disease

    Författare :Jonny Daborg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Synapse; Alzheimer s disease; Genetics; CSF; Complement; RAGE;

    Sammanfattning : The mechanisms behind Alzheimer’s disease (AD) are largely unknown. The disease is to a large extent hereditary, and the best pathophysiological correlate to the severity of the symptoms is loss of synapses. LÄS MER

  4. 3. Kalkbruk-krympsprickor och historisk utveckling av material, metoder och förhållningsätt

    Författare :Jonny Eriksson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Våtsläckning; krympsprickor; kalkbruk; puts; murhantverk; osläckta partiklar;

    Sammanfattning : I denna avhandling undersöks uppkomst av krympsprickor i puts. I undersökningen används våtsläckt sub- hydrauliska kalk. Den aktuella kalksorten har används i Sverige under 1800- och 1900-talet men också under 2000-talet i samband med putsrestaureringar. LÄS MER

  5. 4. Elasto-hydrodynamic film formation in heavily loaded rolling-sliding contacts : Influence of surface topography on the transition between lubrication regimes

    Författare :Jonny Hansen; Roland Larsson; Marcus Björling; Guillermo Morales-Espejel; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : To meet the stringent demands set on future gear transmissions, and to allow for manufacturers to make them more efficient and durable, it is essential to understand what mechanisms that govern their performance. This work was launched with the chief targets of establishing key competence in gear lubrication. LÄS MER

  7. 5. Development of methods and strategies for optimisation of x-ray examinations

    Författare :Jonny Hansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optimisation; visual grading; VGC Analyzer;

    Sammanfattning : The overall aim of the work presented in this thesis was to develop methods and strategies for the optimisation process prescribed by legal authorities for medical X-ray imaging. This overall aim was divided into four detailed aims: 1) to analyse and describe the conditions for the optimisation of a given projectional X-ray examination in a digital environment, 2) to develop an overall strategy for the optimisation work in a radiology department, 3) to develop and implement a suitable method for statistical analysis of visual grading characteristics (VGC) data, and, 4) to evaluate the characteristics of the new statistical method by comparison with receiver operating characteristics (ROC) statistical methodology and by simulations.
