1. Influence of water conditions on growth and mineral nutrient uptake of native plants on clacareous soil
Sammanfattning : The studies presented in Papers I to IV illustrate the importance of soil moisture in soil solution chemistry and response of native plants to the changes induced by change in moisture regime. With the help of glasshouse experiments I tried to study the influence of different treatments of soil moisture conditions on the mineral uptake by native plants of calcareous soil. LÄS MER
2. Thermodynamic properties of humid air and their application in advanced power generation cycles
Sammanfattning : Water or steam is added into the working fluid (often air) in gas turbines to improve the performance of gas turbine cycles. A typical application is the humidified gas turbine that has the potential to give high efficiencies, high specific power output, low emissions and low specific investment. LÄS MER
3. Diffusion tests for assessing leaching from incineration residues
Sammanfattning : Increasing amounts of incineration residues need to be disposed, reused or treated, which calls for reliable characterisation methods. Leaching tests are often used for an assessment of release of pollutants from wastes under a variety of leaching factors. LÄS MER
4. Global Savannah Phenology : Integrating Earth Observation, Ecosystem Modeling, and PhenoCams
Sammanfattning : Savannahs are land areas where grass and trees co-exists to create a landscape that is neither a grassland nor a forest. It is estimated that savannahs cover approximately one sixth of the global land surface. They also play an important role in the global carbon cycle due to their total size. LÄS MER
