1. Hopf and Frobenius algebras in conformal field theory
Sammanfattning : There are several reasons to be interested in conformal field theories in two dimensions. Apart from arising in various physical applications, ranging from statistical mechanics to string theory, conformal field theory is a class of quantum field theories that is interesting on its own. First of all there is a large amount of symmetries. LÄS MER
2. Magneto-optical studies of dilute nitrides and II-VI diluted magnetic semiconductor quantum structures
Sammanfattning : This thesis work aims at a better understanding of magneto-optical properties of dilute nitrides and II-VI diluted magnetic semiconductor quantum structures. The thesis is divided into two parts. The first part gives an introduction of the research fields, together with a brief summary of the scientific results included in the thesis. LÄS MER
3. Molecular and cellular analysis of Lhx2 function in hematopoietic stem cells
Sammanfattning : The formation of blood, hematopoiesis, is a dynamic process originating from a small number of hematopoietic stem cells (HSCs). To sustain hematopoiesis throughout life HSCs have the unique capacity to differentiate into all mature hematopoietic lineages as well as generating more HSCs by a mechanism referred to as self-renewal.

4. Spectroscopic studies of irradiation induced defects in SiC
Sammanfattning : Silicon carbide (SiC) with its applications has the potential to affect the everyday life of most citizens. As a material it has some outstanding properties concerning its mechanical and chemical toughness as well as its electrical properties for high power and high frequency applications. LÄS MER
5. Diamond-Blackfan Anemia: Erythropoiesis Lost in Translation
Sammanfattning : Diamond-Blackfan anemia (DBA) is a congenital erythroid aplasia that usually presents as macrocytic anemia during infancy. Linkage analysis suggests that at least four genes are associated with DBA of which two have been identified so far. LÄS MER
