1. Tracing pathways in the ocean circulation : A temperature and salinity perspective
Abstract : The ocean circulation plays an essential role in our climate system. It redistributes heat, salt, carbon and other tracers across the globe, making the climate of Earth more moderate. This thesis targets density differences that are driving the ocean circulation. These differences are caused by changes in temperature and salinity. READ MORE

3. Short-term effects of ambient temperature on daily deaths and hospital admissions
Abstract : Background: Incidence of death and hospitalizations have been observed to depend on short-term changes in weather and to increase with extreme temperatures. This thesis aims to strengthen the scientific knowledge on the relationship between temperature and daily deaths, but also the relationship between temperature and daily hospital admissions.

4. Neonatal water and heat exchange : The influence of environmental factors and infant maturity
Abstract : The environment provided by commonly used infant incubators, the effect of radiantheat and exposure to cold air on the exchange of water and heat between newborninfants and their environment, and the water loss through the skin of infants born at24-25 weeks of gestation were investigated. The evaporation of water from the skinwas measured by the gradient method. READ MORE

5. Combustion, Fluid Dynamics and Heat Transfer in Oxy-fuel and Air-Fired CFB boilers
Abstract : The studies described in this thesis develop and encode modeling tools for the design and scale-up of oxy-fuel circulating fluidized bed (CFB) boilers across a wide range of operational conditions. The modeling comprises fluid dynamics, combustion, and heat transfer and uses expressions that are proposed in this work or derived from the literature, together with experimental data obtained under both oxy-fuel-fired and air-fired conditions.
