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

    Författare :Anna-Lena Robinson; Claes Olerud; Yohan Robinson; Bengt Lind; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.

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

    Författare :Yngve Gustafson; Gösta Bucht; Bengt Winblad; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

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

    Författare :Jörg Schilcher; Per Aspenberg; Ingemar Ivarsson; Karl Michaëlsson; Olle Svensson; Linköpings universitet; []

    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.

  4. 4. Analysis of transverse composite cross-ply laminates

    Författare :Janis Varna; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 5. Damage accumulation and stiffness degradation in composite laminates

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

    Sammanfattning : In the presented thesis analytical modeling of elastic properties degradation and modeling of damage evolution in composite laminates is performed. Transverse cracking initiation on a fiber/matrix level is briefly studied by testing model composites and cross-ply laminates. LÄS MER
