1. 21. Nanosized Bilayer Disks as Model Membranes for Interaction Studies

   Författare :Anna Lundquist; Katarina Edwards; Marja-Liisa Riekkola; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Disk; disc; lipid bilayer; PEG-lipid; model membrane; interaction; partitioning; drug; liposome; cryo-TEM; neutron scattering; capillary electrophoresis; immobilization; biosensor; membrane protein; melittin; Chemistry; Kemi;

   Sammanfattning : PEG-lipid stabilized bilayer disks have been found in lipid mixtures containing polyethylene glycol (PEG)-lipids where the combination of a high bending rigidity and low PEG-lipid/lipid miscibility favours disk formation. The disks are planar and circular in shape and their long-term stability is excellent. LÄS MER

3. 22. Outcome Assessment in Lumbar Spine Surgery

   Författare :Gustavo Zanoli; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Surgery; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi; Spinal stenosis; Disc; Questionnaire; Outcome assessment; Lumbar spine; Kirurgi; traumatology; orthopaedics; ortopedi;

   Sammanfattning : No consensus regarding outcomes assessment in spine patients exists. Health-Related Quality of Life (HRQoL) questionnaires are increasingly used. The objective of this thesis was the evaluation of HRQoL measures before and after lumbar spine surgery, and their relation to other evaluation parameters as well as relevance of differences.

4. 23. Psychosocial factors in patients with lumbar disc herniation : enhancing postoperative outcome by the identifiction of predictive factors and optimised physiotherapy

   Författare :Ann-Christin Johansson; Steven J. Linton; Karin Harms-Ringdahl; Örebro universitet; []
   Nyckelord :Lumbar disc herniation; surgery; psychosocial factors; physio-therapy; expectations; MEDICINE; MEDICIN; Medicin; Medicine;

   Sammanfattning : Psychosocial factors have been advanced as an explanation for the development of chronic disability in 20 to 30% of patients treated by lumbar disc surgery. Aims: The overall aim of this thesis was to study the role of psychosocial factors in patients undergoing first-time lumbar disc surgery in relation to the outcome of both surgery and subsequent physiotherapy.

5. 24. Improved energy efficiency in double disc chip refining

   Författare :Dino Muhic; Per Engstrand; Lars Sundström; Mats Ullmar; Christer Sandberg; Hans Höglund; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical pulping TMP ; double disc refining; high intensity; Chemical engineering; Kemiteknik;

   Sammanfattning : The electrical energy consumption in thermomechanical pulping (TMP) is very high, in the range of 2 – 3 MWh/adt depending on process solution and on the product quality specifications for the paper product. Both pulpwood and energy prices have increased rapidly for some time. LÄS MER

7. 25. Novel Materials and Implant Designs for the Treatment of Degenerative Disc Disease

   Författare :Salim Ghandour; Cecilia Persson; Donal McNally; Uppsala universitet; []
