1. 1. Shoulder instability : a clinical and MRI-based analysis

   Författare :Björn Salomonsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Shoulder instability; Shoulder instability classification; Shoulder arthroscopy; MRI; MR-arthography; Shoulder instability surgery; Shoulder instability assessment; Outcome instruments;

   Sammanfattning : Shoulder instability is a common but complex and challenging area of shoulder pathology, and new diagnostic methods and treatments are continuously developed. We conducted this study to evaluate the clinical outcome of shoulder instability with respect to different diagnostic possibilities and surgical treatments. LÄS MER

3. 2. Effects of disorder in metallic systems from First-Principles calculations

   Författare :Christian Asker; Igor Abrikosov; Jörg Neugebauer; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Iron; Nickel; Magnesium; Manganese; Molybdenum; Zirconium; Elastic Constants; High pressure; Earth s core; Density-functional theory; Ab-initio; First-Principles; Core-level shifts; Molecular Dynamics; Phonons; Dynamical Instability; Condensed matter physics; Kondenserade materiens fysik; Computational physics; Beräkningsfysik;

   Sammanfattning : In this thesis, quantum-mechanical calculations within density-functional theory on metallic systems are presented. The overarching goal has been to investigate effects of disorder. In particular, one of the properties investigated is the bindingenergy shifts for core electrons in binary alloys using different theoretical methods. LÄS MER

4. 3. From Oxygen to Oxide: First-Principles Study of Some Key Aspects

   Författare :Behrooz Razaznejad; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; potential-enrgy surface; one-dimensional electron gas; adsorption; density functional theory; oxidation; Peierls instability; molecule-surface interaction; plane waves;

   Sammanfattning : Having important technological applications and interesting fundamental science aspects, oxidation of aluminum has received impressive attention. Technologically, the main reason for the great interest is the fact that the oxide film which forms on aluminum protects the surface against further oxidation and corrosion. LÄS MER

5. 4. Knee and ankle kinesiology and joint instability

   Författare :Håkan Gauffin; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : This study, comprising 7 separate papers, is concerned with the additional information supplied by a kinesiological approach for evaluation of patients with instability due to old ligamenta us injury to the knee or ankle joint. This approach required development of new methods for kinesiological analysis. LÄS MER

7. 5. Ankle sprain : subjective and objective measures of functional impairment and treatment

   Författare :Johan Leanderson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Ankle sprain; epidemiology; postural sway; muscle torque; muscle imbalance; proprioception; joint position sense; figure-of-eight running; sick leave; ankle brace treatment; functional instability; basketball; ballet; soccer; taping; Sickness Impact;

   Sammanfattning : This thesis is based upon a series of studies were performed in order to provide more information about the etiology of late symptoms after ankle sprain, most often referred to as functional instability of the ankle joint. In a retrospective study of basketball players, the incidence of ankle sprains and the prevalence of late symptoms after such an injury were investigated. LÄS MER
