1. 6. Ganglionic nerve fibres in ventral roots

   Författare :Magnus Karlsson; Mårten Risling; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : According to the law of Magendie, the ventral roots channel efferent nerve fibres from the spinal cord to the periphery, while the dorsal roots channel afferent axons from the periphery into the spinal cord. However, as sensory C-fibres have been observed in mammalian ventral roots outside the autonomic outflow, this law has been questioned. LÄS MER

3. 7. Phosphine ligands with triamine functionality - preparation and application in catalysis

   Författare :Magnus Karlsson; Enheten för fysikalisk och teoretisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; water soluble; palladium; amphiphilic; rhodium; Oorganisk kemi;

   Sammanfattning : Incorporation of the triamine, bis(2-diethylaminoethyl) amine as a side chain substituent on triphenylphosphine, (2S,4S)-4-diphenylphosphino-2-diphenylphosphino-methylpyrrolidine (PPM) or (R,R)-3,4-bis(diphenylphosphin)pyrrolidine (Pyrphos) gives the three new amphiphilic ligands N3P, N3PPM and N3-Pyrphos respectively. Because of the triamine functionality the distribution of the ligands and their complexes between water and an organic solvent is controlled by the pH of the aqueous phase. LÄS MER

4. 8. Själv men inte ensam : om självhjälpsgrupper i Sverige

   Författare :Magnus Karlsson; Töres Theorell; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; self-help group; mutual aid group; mutual understanding; mutual support; experiential knowledge; professional knowledge; voluntary work; Självhjälpsgrupper; Sverige; Self-help groups; Social support; socialt arbete; Social Work; Social work;

   Sammanfattning : In this thesis, self-help groups are defined as small, autonomous groups of people that meet regularly to cope with a shared problem through mutual aid. There is reason to believe that self-help group activity is increasing in Sweden. LÄS MER

5. 9. Static and Dynamic Modelling of the Drying Section of a Paper Machine

   Författare :Magnus Karlsson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pappers- och massateknik; Modelling; Wood; Paper; Multi-Cylinder; Simulation; Control; Steam; Air; Dew Point; Moisture Gradients; pulp and paper technology; Pressure Gradients;

   Sammanfattning : The paper making process involves chopping of wood, cooking and forming, followed by dewatering in a vacuum section, press section and drying section. Several models for the most important parts of the paper machine drying section are presented in this thesis to describe phenomena at steady state and during state transitions. LÄS MER

7. 10. The liberalisation of telecommunications in Sweden : Technology and regime change from the 1960s to 1993

   Författare :Magnus Karlsson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; telecommunications; liberalisation; deregulation; international regimes; national regimes; sociotechnical systems; large technical systems; technological convergence; Sweden; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : This study describes the liberalisation of telecommunications in Sweden and analyses the role of technology in this process. The stable and largely successful traditional monopoly regime was challenged in the 1980s by the development of new technologies and the general trend towards market orientation and competition.
