  1. 1. Hopf and Frobenius algebras in conformal field theory

    University dissertation from Karlstad : Karlstad University Press

    Author : Carl Stigner; Jürgen Fuchs; Jens Fjelstad; Ingo Runkel; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conformal field theory; category theory; Hopf algebra; Frobenius algebra; coends; mapping class group; defect lines; factorization constraints; Physics; Fysik;

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

  3. 3. Molecular and cellular analysis of Lhx2 function in hematopoietic stem cells

    University dissertation from Umeå : Umeå centrum för molekylär medicin (UCMM)

    Author : Karin Richter; Leif Carlsson; Andrew Elefanty; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hematopoietic stem cells; Lhx2; cell lines; self renewal; SCF; IL-6; chronic myeloproliferative disorder; global gene expression analysis; NATURAL SCIENCES Chemistry Biochemistry Molecular biology; NATURVETENSKAP Kemi Biokemi Molekylärbiologi;

    Abstract : 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. 4. Spectroscopic studies of irradiation induced defects in SiC

    University dissertation from Linköping : Linköpings universitet

    Author : Fredrik Carlsson; Peter Deák; [2003]

    Abstract : 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. READ MORE

  5. 5. Diamond-Blackfan Anemia: Erythropoiesis Lost in Translation

    University dissertation from Faculty of Medicine, Lund University

    Author : Johan Flygare; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Hematologi; Haematology; RNA interference; Erythropoiesis; Lentiviral vectors; Nucleolus; Diamond-Blackfan anemia; Gene therapy; extracellulära vätskor;

    Abstract : 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. READ MORE
