Sammanfattning : Thermal barrier coatings (TBC) are applied on hot components in airborne and land-based gas turbines when higher turbine inlet temperature, meaning better thermal efficiency, is desired. The TBC is mainly applied to protect underlying material from high temperatures, but also serves as a protection from the aggressive corrosive environment. LÄS MER
2. Failure of thermal barrier coatings under thermal and mechanical fatigue loading : microstructural observations and modelling aspects
Sammanfattning : Industrial and air-borne gas turbine hot components suffer from creep, oxidation, corrosion and microstructural degradation if not shielded from the hot and aggressive combustion gases. Two major strategies commercially available are adopted; film cooling by pressurised air and application of protective coatings. LÄS MER
Sammanfattning : Secondary, non-sample data, mainly from official statistics from 259 municipalities in Sweden, are used to investigate systematic variations in the consumptian of pharmaceuticals on the county and municipality level. The theoretical framework is taken from health economics. LÄS MER
4. Diagnostic and Prognostic Value of Exercise Electrocardiographic Test Variables in Coronary Artery Disease
Sammanfattning : The diagnostic performance of conventional analysis of the exercise electrocardiographic (ECG) test for the detection of coronary artery disease (CAD) is limited to 70-75%. The exercise ECG test is the most widely used non-invasive method for assessing CAD and even a small improvement in the diagnostic performance is important. LÄS MER
Sammanfattning : Gas turbines are widely used in industry for power generation and as a power source at hard to reach locations where other possibilities for electrical power supplies are insufficient. New ways of producing greener energy is needed to reduce emission levels. This can be achieved by increasing the combustion temperature of gas turbines. LÄS MER
