1. On the Late Saalian glaciation : A climate modeling study
Sammanfattning : This thesis focuses on the glaciation of the Late Saalian period (160 -140 ka) over Eurasia. The Quaternary Environment of the Eurasian North (QUEEN) project determined that during this period, the Eurasian ice sheet was substantially larger than during the entire Weichselian cycle and especially that of the Last Glacial Maximum (21 ka, LGM).

2. Understanding West African Monsoon Variability : Insights from Paleoclimate Modelling of Past Warm Climates
Sammanfattning : The Sahel, a water-vulnerable region in West Africa, relies heavily on rainfed agriculture. The region experienced pronounced droughts during the 20th Century, emphasising the socio-economic importance of understanding the drivers of the rainfall variability. LÄS MER
3. Numerical and experimental study of confluent jets supply device with variable airflow
Sammanfattning : In recent years, application of confluent jets for design of ventilation supply devices has been studied. Similarly, numerus studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. LÄS MER
4. Diagnosing hyper- and hypocortisolism using saliva samples : pitfalls and how to avoid them
Sammanfattning : Background: Cushing's syndrome (CS) is caused by high cortisol secretion whereas insufficient cortisol secretion is called adrenal insufficiency (AI). Both are rare diseases with substantial diagnostic delay, and high morbidity and mortality even though effective treatment is available. LÄS MER
5. Computational Modelling for Cavitation and Tip Vortex Flows
Sammanfattning : Cavitation often brings negative effects, such as performance degradation, noise, vibration, and material damage, to marine propulsion systems, but for optimum performance, cavitation is almost inevitable. Therefore, it is necessary to better understand cavitation in order to maximize the performance without encounter- ing severe problems. LÄS MER
