1. 1. Solubility of Np(IV), Zr(IV), and Reactive Transport Modeling with Uncertainty Calculations

   Författare :Göran Källvenius; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Sweden, as some other countries, is planning to construct a repository for long-lived low and intermediate level radioactive waste. The planned repository is a concrete construction in the bedrock a few hundreds of meters below the surface. LÄS MER

3. 2. The Use of Aliquat-336 in a Partitioning and Transmutation Process and a Kinetic Study of the Oxidation of U(IV) to U(VI)

   Författare :Anders Landgren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; partitioning; quaternary ammonium salts; transmutation; hydrolysis; Aliquat-336; liquid-liquid extraction; kinetics; oxidation; uranium IV ;

   Sammanfattning : Spent nuclear fuel contains several long-lived radionuclides that must be stored in a safe manner for a long time. Transmutation of these radionuclides into short-lived or stable nuclides reduces the necessary storage time by several orders of magnitude. The nuclides most suitable for transmutation are those of the actinides. LÄS MER

   Sammanfattning : This thesis investigates the anti-leukemic activity of terpenoids isolated from medicinal mushrooms and marine sponges, as well as their possible targets and mechanisms of action.In the first section, we focused on studying the triterpenoidal components of three triterpenoid-enriched medicinal mushrooms Antrodia cinnamomea, Ganoderma lucidum, and Poria cocos, which have been used in folk medicine for centuries and also developed into several contemporary marketed products.

5. 4. Effects of intervertebral disc cells on neural tissue. In vitro and in vivo experimental studies

   Författare :Karin Larsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intervertebral disc; nerve damage; nucleus pulposus; notochordal cells; chondrocyte-like cells;

   Sammanfattning : Introduction: Lumbar disc herniation and sciatica are common conditions that involve interactions between intervertebral discs (IVDs) and neural tissue. The nucleus pulposus (NP) of an IVD contains at least two cell populations, notochordal cells and chondrocyte-like cells. LÄS MER

7. 5. The effects of aerobic exercise and the impact of migraine and co-existing tension-type headache and neck pain

   Författare :Lotte Skytte Krøll; Människan i rörelse: hälsa och rehabilitering; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; migraine; tension-type headache; neck pain; aerobic exercise; impact; pain perception; validation;

   Sammanfattning : The overall aims of this thesis were to investigate the effects of an aerobic exercise program and the impact of migraine and co-existing TTH and NP in persons with these combined conditions. This thesis is based on four studies.In study I, a new questionnaire, Impact of Migraine, TTH and NP (Impact M-TTH-NP), was developed. LÄS MER
