1. Peroxyoxalate Chemiluminescence for Miniaturized Analytical Flow Systems
Sammanfattning : This thesis deals with the peroxyoxalate chemiluminescence (POCL) reaction and its application as a detection technique in flow systems for chemical analysis. Particularly, miniaturized flow systems aimed for separation of molecules. LÄS MER
2. Cut finite element methods on parametric multipatch surfaces
Sammanfattning : .... LÄS MER
3. Cut isogeometric methods on trimmed multipatch surfaces
Sammanfattning : Partial differential equations (PDE) on surfaces appear in a variety of applications, such as image processing, modeling of lubrication, fluid flows, diffusion, and transport of surfactants. In some applications, surfaces are drawn and modeled by using CAD software, giving a very precise patchwise parametric description of the surface. LÄS MER
4. The Role of Fibroblast Growth Factor 23 in Phosphate Homeostasis
Sammanfattning : The regulation of serum phosphate (Pi) concentrations is a complex process and our current models are far from complete. Due to major advancements in biotechnology and the development of more powerful research tools, recent advances in the field of genetics has led to the identification of several candidates for the long sought-after phosphatonin(s), or Pi regulating hormones.

5. Fibroblast growth factor-23 and Klotho in bone/mineral and parathyroid disorders
Sammanfattning : Fibroblast growth factor-23 (FGF23) is a novel, bone-produced hormone that regulates renal phosphate (Pi) reabsorption and calcitriol metabolism. Disorders of mineral and bone metabolism, such as autosomal dominant hypophosphatemic rickets (ADHR) and hyperostosis-hyperphosphatemia syndrome (HHS), witness the importance of well-balanced serum levels of FGF23.
