2. Silicon δ-doping and Isoelectronic Doping in GaAs ans GaN Layers Grown by MBE
Sammanfattning : This work concerns MBE-grown material, particularly physical effects due to controlled impurities of Si and N in arsenides, and the growth of nitrides and studies of Al- and As-impurities in them. Apart from interesting physical phenomena there are important device applications. The first part is devoted to studies of Si .delta. LÄS MER

4. Antioxidants in Andean food and meals
Sammanfattning : Abstract The constant need to improve health and to prevent disease in Bolivia, especially in the Andean region with its extreme environmental conditions (high altitude and lower temperatures), motivated us to extend studies of antioxidant sources in foods and plants, since antioxidants are believed to have major health benefits. Spectrophotometric methods, such as ABTS (2, 2’- azinobis-3-ethylbenzotiazoline-6-sulfonic acid) and FRAP (ferric reduction antioxidant power), were used to evaluate antioxidant activity. LÄS MER
5. Efficient Trading in the Short-term Electricity Markets for Integration of Renewable Energy Sources : Multistage Stochastic and Agent-based Modeling Approaches for Continuous Intraday Electricity Market
Sammanfattning : This thesis investigates the role of different short-term electricity market design aspects that can facilitate better coordination of resources within the power system. The work also emphasizes on better cross-border integration of the short-term markets to improve the market liquidity, competition, social welfare, and flexibility in the system, which is essential for facilitating the integration of renewable sources.
