  2. 1. Static and Dynamic Correlation Effects in Atoms

    Author : Nils-Erik Dahlen; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic and optical properties; electrical; Condensed matter:electronic structure; relaxation; magnetic resonance; supraconductors; spectroscopy; Kondenserade materiens egenskaper:elektronstruktur; Atom- och molekylärfysik; Atomic and molecular physics; spektroskopi; magnetisk resonans; egenskaper elektriska; supraledare; magnetiska och optiska ; variational energies; double ionization; Electron correlation; laser-atom interaction; Fysicumarkivet A:2002:Dahlen; conserving approximations; Green s functions; GW-approximation;

    Abstract : The thesis considers the effects of electron correlation by studying the two opposite limits of atoms in the ground state and atoms in strong laser pulses. Computational methods and theoretical approaches differ significantly due to the different physical processes that are studied in these two cases. READ MORE

    Author : Ashk Dahlén; Yann Richard; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Languages and linguistics; Islam; Shi’i; Iran; sharīʿat; fiqh; uṣūl al-fiqh; ikhtilāf; qabḍwa basṭ; Surūsh; Jawādī-Āmulī; Mujtahid-Shabistarī; Rūmī; epistemology; hermeneutics; history of philosophy and science; postmodernism; modernity; mysticism; relativism; interpretation; Språkvetenskap; Languages and linguistics; Språkvetenskap; Iranska språk; Iranian Languages;

    Abstract : This study analyses the major intellectual positions in the philosophical debate on Islamic law that is occuring in contemporary Iran. As the characteristic features of traditional epistemic considerations have a direct bearing on the modern development of Islamic legal thought, the contemporary positions are initially set against the established normative repertory of Islamic tradition.

  5. 3. Genetic Characterization of Bone and Soft Tissue Tumors

    Author : Anna Dahlen; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical genetics; Klinisk genetik; cytogenetik; Genetik; cytogenetics; mesenchymal tumor; pericytoma; Genetics; chondroma; lipoma;

    Abstract : Bone and soft tissue tumors (BSTT) constitute a heterogeneous group of neoplasms of mesenchymal and neuroectodermal origin. Although many BSTT are rare, it has become clear that BSTT are characterized by recurrent acquired chromosomal aberrations, and the general aim of this thesis have been to apply molecular genetic and molecular cytogenetic techniques to further characterize recurrent breakpoints and deletions, and to search for candidate target genes.

  7. 5. Antigen presenting cells in autoimmune diabetes: phenotype, function and modulation by Linomide

    Author : Eva Dahlén; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; secreting systems; Endocrinology; Linomide; costimulation; TNF-a; dendritic cells; Diabetes; macrophages; diabetology; Endokrinologi; sekretion; diabetologi; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : The aim of this thesis was to better understand the role of antigen presenting cells (APC) in the development of diabetes in the nonobese diabetic (NOD) mouse. We have shown that DC and Mphi that infiltrate the islets of Langerhans produce tumour necrosis factor-a (TNF-a), a cytokine known to contribute to the pathogenesis in the early stages of diabetes development.
