    Sammanfattning : Inverse problems arise in any scientific endeavor. Indeed, it is seldom the case that our senses or basic instruments, i.e., the data, provide the answer we seek. LÄS MER

  3. 3. Developing into early adulthood: The role of identity and personality

    Författare :Py Liv Eriksson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :identity development; identity process; narrative identity; personality development; ego resiliency; ego control; early adulthood; cultural context;

    Sammanfattning : The overall aim of this thesis was to investigate the development into early adulthood, focusing on identity and personality. The aim of Study I was to explore the developmental course and implications of the two meta-traits ego resiliency (i.e., individuals’ capacity to adjust to their environment) and ego control (i.

    Sammanfattning : Apoptosis is one of the most common types of cell death. Under physiological conditions, it plays an essential role in removal of damaged and potentially harmful cells. Excessive apoptosis has however been linked to a number of diseases including proteinuric kidney disease and DKD, and is believed to enhance the disease progression. LÄS MER

  5. 5. A clinical study of uncemented hip arthroplasty : Radiological findings of host-bone reaction to the stem

    Författare :Henrik Bodén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Arthroplasty; bone remodelling; DEXA; fixation; geometrical design; hydroxyapatite; osteoarthritis; scintigraphy; stem size; stress-shielding; tapered; titanium; uncemented; weight-bearing.;

    Sammanfattning : In total hip arthroplasty (THA), the main reason for failure leading to revision is aseptic loosening. Both mechanical and biological effects act in the loosening process, the factors may be implant design, fixation mode or technique, as well as biological factors unique to the individual. LÄS MER
