1. Steam Turbine Optimisation for Solar Thermal Power Plant Operation
Sammanfattning : The provision of a sustainable energy supply is one of the most important issues facing humanity at the current time, given the strong dependence of social and economic prosperity on the availability of affordable energy and the growing environmental concerns about its production. Solar thermal power has established itself as a viable source of renewable power, capable of generating electricity at some of the most economically attractive rates. LÄS MER
2. Induced hypothermia after cardiac arrest
Sammanfattning : This thesis is based on studies of the clinical use of induced hypothermia as an intervention to reduce mortality and neurological impairment after cardiac arrest. After the publication of two trials indicating benefit of induced hypothermia, we developed a registry to assess outcome, possible adverse events and conduct of induced hypothermia when this intervention was implemented in a clinical population of cardiac arrest patients.

3. Severe Hemodilution - Clinical and Experimental Studies
Sammanfattning : In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23 occasions in 19 children, 1-17 years of age, with healthy hearts and lungs.

4. On the polymer-based nanocomposites for electrical switching applications
Sammanfattning : Recent research demonstrated that polymer based nanocomposites (PNCs) have been engineered in order to improve the arc interruption capability of the circuit breakers. PNCs are the combination of nano-sized inorganic nanoparticles (NPs) and polymers, opened up new developments in materials science and engineering applications. LÄS MER
5. Cooling and dopamine
Sammanfattning : There is little knowledge about the circulatory effects of dopamine in hypothermia. Induced hypothermia has been shown to improve outcome in various settings. Hypothermia is also used for preservation of organs that are harvested for transplantation. LÄS MER
