2. 1. Electronic structure and spectroscopy calculations in fuel cell catalysis

   Author : Henrik Öberg; Lars G.M. Pettersson; Göran Lindbergh; Stockholms universitet; []
   Keywords : Chemical Physics; kemisk fysik;

   Abstract : This thesis presents joint experimental and theoretical studies of surface phenomena at an electronic structure level in proton exchange membrane fuel cells (PEM-FC's). The fuel cell activity can be related to the oxygen reduction taking place at the cathodic surface through the oxygen reduction reaction (ORR). READ MORE

4. 2. Surface reactions and chemical bonding in heterogeneous catalysis

   Author : Henrik Öberg; Lars G. M. Pettersson; Philippe Sautet; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

   Abstract : This thesis summarizes studies which focus on addressing, using both theoretical and experimental methods, fundamental questions about surface phenomena, such as chemical reactions and bonding, related to processes in heterogeneous catalysis. The main focus is on the theoretical approach and this aspect of the results. READ MORE

5. 3. Fighting for Aid : Foreign Funding and Civil Conflict Intensity

   Author : Daniel Strandow; Magnus Öberg; Michael G. Findley; Kristian Skrede Gleditsch; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aid; foreign aid; foreign assistance; relief; humanitarian; conflict; civil war; civil conflict; geographic concentration; intra-state; violence; military; contest; low-intensity; guerrilla; irregular; conventional; decision theory; contest success function; geo-coding; geo-referencing; territorial control; propensity score; Africa; South of the Sahara; Peace and Conflict Research; Freds- och konfliktforskning;

   Abstract : This dissertation focuses on the sub-national impact of foreign aid on civil conflicts by asking the question: How does foreign aid committed to contested areas affect the intensity of violence in those areas? The main theoretical contribution is to focus on how aid influences warring parties’ decisions to engage in contests over territorial control and how that in turn influences violence intensity. The study introduces two concepts: funding concentration and barriers to exploiting aid. READ MORE

6. 4. Persistent Organic Pollutants and the Environment : A Chemometric Approach to the Study of Halogenated Aromatics

   Author : Tomas Öberg; Bo Bergbäck; Bo Wiman; Jaakko Paasivirta; Högskolan i Kalmar; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

   Abstract : Concern is growing about the environmental and health effects of persistent organic pollutants (POPs), many of which are halogenated aromatic compunds. The research reported in this thesis focuses on factors determining their behaviour and release into the environment. READ MORE

7. 5. Health consequences of adverse fetal growth : studies in twins

   Author : Sara Öberg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Findings of associations between birth weight and adult health outcomes have been taken to indicate that fetal growth – and fetal nutrition in particular – may program future health and disease in the developing individual. However, the study of prenatal exposures in humans is challenging, and most of the evidence to support fetal programming thus rests on proxy measures, such as birth weight and birth weight for gestational age.
