16. X-ray scattering and spectroscopy of supercooled water and ice
Sammanfattning : This thesis presents experimental studies of water and ice at near-atmospheric pressures using intense x-rays only accessible at synchrotrons and free-electron lasers. In particular, it focuses on the deeply supercooled, metastable state and its implications on ice nucleation. LÄS MER
17. Single exposure phototesting and assessment of pigmented skin lesions : quantitative methods in terms of blood perfusion estimates
Sammanfattning : This thesis concerns the development of quantitative phototesting for the investigation of individual skin sensitivity to ultraviolet (UV) radiation, and the assessment of pigmented skin lesions (PSL) in terms of blood perfusion estimates. In both cases, laser Doppler perfusion imaging (LDPI) was used to quantify the perfusion. LÄS MER
18. Production scheduling and shipment planning at oil refineries : optimization based methods
Sammanfattning : In the oil refinery industry, companies need to have a high utilization of production, storage, and transportation resources to be competitive. This can only be achieved by proper planning The purpose of this thesis is to contribute to the development of optimization models and solution methods that support the scheduling and planning at refinery companies.

19. Application-oriented experiment design for industrial model predictive control
Sammanfattning : Advanced process control and its prevalent enabling technology, model predictive control (MPC), can today be regarded as the industry best practice for optimizing production. The strength of MPC comes from the ability to predict the impact of disturbances and counteract their effects with control actions, and from the ability to account for constraints. LÄS MER
20. Inhibition of 11 ß-HSD. Hemodynamic and hormonal response induced by liquorice
Sammanfattning : Introduction: The enzyme 11 ß-hydroxysteroid-dehydrogenas (11 ß-HSD) type 2 that converts the active hormone cortisol to the inactive cortisone is inhibited by glycyrrhetinic acid (GA), the active substance in liquorice. This leads to hypertension, hypokalaemia and sodium- and fluid retention, the syndrome of pseudo-hyperaldosteronism. LÄS MER
