  1. 1. A thesis on fire : Studies of work engagement, Type A behavior and burnout

    Författare :Ulrika Eriksson Hallberg; Gunn Johansson; Wilmar Schaufeli; Irene Jensen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Work engagement; Type A behavior; burnout; construct validity; job stress; ‘on fire’; Psychology; Psykologi;

    Sammanfattning : The overall address of the present thesis is the relationship between being ‘on fire’ and burning out. More specifically, the thesis focused largely on two representations of involvement in work (work engagement and Type A behavior) and their respective relationships to burnout. LÄS MER

  3. 2. Applanation Resonance Tonometry for Intraocular Pressure Measurement

    Författare :Per Hallberg; Olof A. Lindahl; Anders Eklund; Christina Lindén; Per Ask; Umeå universitet; []
    Nyckelord :Physics; Resonance; applanation; tonometry; glaucoma; Goldmann; biomechanical; Intraocular; ART; Fysik; fysik; Physics;

    Sammanfattning : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. LÄS MER

  4. 3. Disassembly and reassembly of the nuclear pore complex

    Författare :Evgeny A. Onischenko; Einar Hallberg; Paul R. Clarke; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The nuclear pore complexes (NPCs) are multiprotein communicative channels spanning the nuclear envelope. In higher eukaryotes NPCs reversibly disassemble during mitosis into distinct nucleoporin subcomplexes. Some cell types (e.g. LÄS MER

  5. 4. The functional organization of nuclear membrane proteins and development of new technology for studies of cell signaling

    Författare :Ricardo A. Figueroa; Einar Hallberg; Yosef Gruenbaum; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Sammanfattning : The eukaryotic cell is defined by the nucleus, which is delimited by a double membrane structure termed the nuclear envelope (NE). The NE is implicated in a multitude of different processes, for example chromatin organization. LÄS MER

  7. 5. Regioselective Heck Coupling Reactions : Focus on Green Chemistry

    Författare :Karl S. A. Vallin; Anders Hallberg; Mats Larhed; Walter Cabri; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Medicinal Chemistry; läkemedelskemi;

    Sammanfattning : Carbon-carbon bond formation reactions are among the most important processes in chemistry, as they represent key steps in the synthesis of more complex molecules from simple precursors. This thesis describes mainly the development of novel regioselective applications of the mild and versatile palladium-catalyzed carbon-carbon coupling method, commonly known as the Heck reaction.
