  1. 1. Axis Fractures in Elderly : Epidemiology and Treatment related outcome

    Författare :Anna-Lena Robinson; Claes Olerud; Yohan Robinson; Bengt Lind; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; odontoid fracture; treatment; elderly; cervical spine; axis fracture; Orthopaedics; Ortopedi;

    Sammanfattning : Background: Axis fractures are a common injury in the elderly population. Treatment is often complicated due to osteoporosis and patient comorbidity. Knowledge of the incidence of these fractures, as well as their treatment, outcome and mortality rate, will improve knowledge and decision-making processes for this fragile group of patients.

  3. 2. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites

    Författare :Erik Jungstedt; Lars Berglund; Sören Östlund; Bent Sørensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; fracture mechanics; strain field measurement; cohesive zone modeling; mechanical properties; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. LÄS MER

  4. 3. Acute confusional state (delirium) : clinical studies in hip-fracture and stroke patients

    Författare :Yngve Gustafson; Gösta Bucht; Bengt Winblad; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute confusional state; delirium; elderly; stroke; femoral neck fractures; acetylcholine; cortisol;

    Sammanfattning : Acute confusional state (ACS) or delirium according to DSM-III-R holds a central position in the medicine of old age. ACS is a common and sometimes the only symptom of diseases and medical complications in the elderly patient. LÄS MER

  5. 4. Epidemiology, Radiology and Histology of Atypical Femoral Fractures : Development of understanding

    Författare :Jörg Schilcher; Per Aspenberg; Ingemar Ivarsson; Karl Michaëlsson; Olle Svensson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE;

    Sammanfattning : Bisphosphonates have been used successfully in the prevention of osteoporosis-related fractures for over two decades. Only recently an association between bisphosphonate use and femoral insufficiency fractures – atypical femoral fractures – has been found.Bone remodeling is necessary to maintain a healthy skeleton.

  7. 5. Analysis of transverse composite cross-ply laminates

    Författare :Janis Varna; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Advanced polymer composites are commonly based on thin prepreg plies stacked at different angles to form a laminate. When the laminate is loaded, intralaminar transverse cracking in off-axis plies is one of the first damage modes. In the presented thesis, cross-ply laminates are used to study the transverse cracking phenomenon. LÄS MER
