    Sammanfattning : Heterogeneous electrocatalysis is the usage of solid materials to decrease the amount of energy needed to produce chemicals using electricity. It is of core importance for modern life, as it enables production of chemicals, such as chlorine gas and sodium chlorate, needed for e.g. materials and pharmaceuticals production. LÄS MER

  3. 27. Studies on Vitamin A Signaling in Psoriasis : A Comparison Between Normal and Lesional Keratinocytes

    Författare :Teresa Karlsson; Jan Öivind Moskaug; Uppsala universitet; []
    Nyckelord :Medical sciences; Psoriasis; vitamin A; retinoids; retinoid receptor; differentiation; keratinocyte; skin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Dermatology and Venerology; dermatologi och venereologi;

    Sammanfattning : Vitamin A and metabolites (retinoids) are crucial for normal epidermal maturation. Physiological effects are mediated by retinoic acid (RA) that activates nuclear retinoic acid receptors (RARs) in complexes with retinoid X receptors (RXRs), resulting in altered gene transcription.Psoriasis is a common disease with unknown etiology.

  5. 29. Anorexia nervosa : treatment expectations, outcome and satisfaction

    Författare :Gunilla Paulson-Karlsson; Lauri Nevonen; Ingemar Engström; Jan Rosenvinge; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anorexia nervosa; treatment; adolescents; adults; expectations; outcome; predictors; weight increase; satisfaction; Medicine; Medicin;

    Sammanfattning : Anorexia nervosa is a serious mental disorder with high mortality. It has the lowest prevalence compared with other eating-disorder diagnoses and the onset is related to adolescence, with a majority of female patients. LÄS MER

  7. 30. Double Excitations in Helium Atoms and Lithium Compounds

    Författare :Marcus Agåker; Jan-Erik Rubensson; Leif Karlsson; David Ederer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Soft X-ray emission; resonant inelastic X-ray scattering; double excitations; lithium halide; helium; Atom- och molekylfysik;

    Sammanfattning : This thesis addresses the investigation of doubly excited 2l´nl states in helium atoms and double core excitations in solid lithium compounds.Measurements on He are made in field free environments and under the influence of electric and magnetic fields, using synchrotron based inelastic photon scattering.
