  1. 1. Radial head and neck fractures

    Författare :Pär Herbertsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General pathology; Elbow dislocation; Radial neck; Radial head; Fracture; Long-term; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Sammanfattning : All elbow fractures between 1969 – 1979 (n=2965) registered at the radiographic archives at the Malmö University Hospital, where all radiographs are saved since a century, were evaluated. Fractures of the radial head and neck were classified according to the by Broberg and Morrey modified Mason classification. LÄS MER

  3. 2. Prevention of Head Injuries - focusing Specifically on Oblique Impacts

    Författare :Magnus Aare; KTH; []
    Nyckelord :head injury; helmets; oblique impacts; FEM;

    Sammanfattning : The massive number of injuries sustained in trafficaccidents is a growing problem worldwide, especially indeveloping countries. In 1998, more than one million peoplewere killed in traffic accidents worldwide, while about tentimes as many people were injured. LÄS MER

  4. 3. FLOW FIELD IN A HIGH HEAD FRANCIS TURBINE DRAFT TUBE DURING TRANSIENT OPERATIONS

    Författare :Rahul Goyal; Michel J. Cervantes; Bhupendra K. Gandhi; Gabriel Ciocan; Lisa Prahl; Ramis Orlu; Gunilla Andree; Andrea Toffolo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Francis turbine; Steady state; Transient; Particle Image Velocimetry; Vortex Rope; Strömningslära; Fluid Mechanics;

    Sammanfattning : Hydroelectricity plays an important role to balance the stability of grid network.  In order to improve the stability of presently high loaded grids, hydropower plants are being operated over a wide range of operations and experiencing frequent start-stop, load rejection, and load acceptance.

  5. 4. Arthroplasty in Elbow Fracture Treatment

    Författare :Jens Nestorson; Lars Adolfsson; Carl Ekholm; Ola Wahlström; Simon Lambert; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Open reduction and internal fixation is the treatment of choice for distal humeral fractures. Stable fixation is required to allow early mobilisation and to reduce the risk of poor functional results. In an elderly patient with osteoporotic bone and with a comminuted intra-articular fracture stable internal fixation can be difficult to achieve. LÄS MER

  7. 5. Effects of boundary conditions and unsteadiness on draft tube flow

    Författare :Michel Cervantes; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The present research focuses on flow properties of the elbow draft tube. This element has a major function in low head turbines, since up to half of the losses may arise there at part load. The use of computational fluid dynamic (CFD) to redisign a draft tube necessitates detailed knowledged of the boundary conditions. LÄS MER
