  1. 1. Radial head and neck fractures

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

    Abstract : 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. READ MORE

  2. 2. Conduits in coronary artery bypass grafting surgery : Saphenous vein, radial and internal thoracic arteries

    Author : Mats Dreifaldt; Domingos Souza; Lars Norgren; Mats G. Karlsson; Michael R. Dashwood; Anders Jeppson; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac surgery; Coronary artery bypass; Saphenous vein; Radial artery; Internal thoracic artery; Vasa vasorum; Nitric oxide; Graft patency; Medicine; Medicin;

    Abstract : A novel technique for saphenous vein (SV) graft harvesting, the No-touch technique (NT), has been developed at the Dept. of Cardiovascular surgery, Örebro University hospital. With NT the SV is harvested with a pedicle of surrounding tissue. This avoids graft spasm and eliminates the need for distension. READ MORE

  3. 3. Radial Velocities Without Spectroscopy -Astrometric determination of stellar radial motion

    Author : Søren Madsen; Astronomi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Astronomi; Hipparcos; Astronomy; space research; cosmic chemistry; astrometry; stellar astrophysics; N-body simulations; Open clusters and associations; cluster kinematics and dynamics; rymdvetenskap; kosmisk kemi;

    Abstract : This work demonstrates the determination of absolute stellar radial velocities from geometrical principles, i.e. using astrometry. Such `astrometric radial velocities' are obtained independently of spectroscopic information. READ MORE

  4. 4. Engine Optimized Turbine Design

    Author : Nicholas Anton; Anders Christiansen-Erlandsson; Magnus Genrup; Marc Gugau; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Turbocharger; Heavy-duty; Turbine; Axial; Radial; Machine Design; Maskinkonstruktion;

    Abstract : The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. READ MORE

  5. 5. Numerical computations of the unsteady flow in a radial turbine

    Author : Fredrik Hellström; Laszlo Fuchs; Jonas Bredberg; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulsatile flow; radial turbines; pipe flow; effects of inlet conditions; Fluid mechanics; Strömningsmekanik;

    Abstract : Non-pulsatile and pulsatile flow in bent pipes and radial turbine has been assessed with numerical simulations. The flow field in a single bent pipe has been computed with different turbulence modelling approaches. READ MORE
