1. The Role of Kidney Oxygen Homeostasis for the Development of Kidney Disease
Sammanfattning : The relation between oxygen supply and demand determines tissue oxygen tension (PO2). When intrarenal tissue PO2 decreases, any compensatory increase in oxygen supply via increased renal blood flow is likely to increase glomerular filtration rate. LÄS MER
2. Fate of Trace Elements in Thermochemical Conversion of Waste Fuels Using Oxygen Carriers
Sammanfattning : The metals zinc, copper and lead are amongst the more abundant trace elements in waste fuels. The fate of these elements is important to study because they can affect the thermochemical conversion process and end up in ashes. LÄS MER
3. Oxygen carrier aided combustion: Implementation of oxygen carriers to existing industrial settings
Sammanfattning : Utilization of biomass and waste to produce heat and power is necessary for a sustainable future energy mix. Thermal conversion of biomass is considered to yield CO2 neutral emissions and the utilization of waste reduces its volumes in a world struggling to dispose of ever-increasing amounts. LÄS MER
4. The Baltic Sea marine system - human impact and natural variations
Sammanfattning : The environmental state of the Baltic Sea system is influenced by both natural and anthropogenic factors. Water exchange with the adjacent ocean and within the system depend on large-scale atmospheric circulation and properties of the straits separating the different sub-basins. LÄS MER
5. Quantification of mineral weathering rates in sulfidic mine tailings under water-saturated conditions
Sammanfattning : Tailings are a fine-grained waste product produced during the metal recovery process. Tailings consist mostly of different silicates but also sulfides (e.g. pyrite), since 100 % metal recovery is not possible. LÄS MER
