  1. 6. Alternative Methods for Assessment of Split Renal Function

    Författare :Henrik Björkman; Anders Magnusson; Jonas Wadström; Torbjörn Andersson; Uppsala universitet; []
    Nyckelord :Radiology; Split renal function; Live kidney donor; CT; Renography; Dynamic MRI; Renal volume; Respiratory triggering; Radiologisk forskning;

    Sammanfattning : Living kidney donation is a clinical situation with unique features in the sense that healthy individuals voluntarily expose themselves to certain risks and inconveniences. Therefore, eliminating as much of the associated discomfort as possible is crucial. LÄS MER

  3. 7. Accurate Finite Difference Methods for Option Pricing

    Författare :Jonas Persson; Lina von Sydow; Per Lötstedt; Johan Tysk; Jari Toivanen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Finite differences; Option pricing; Adaptive methods; Numerical Analysis; Numerisk analys;

    Sammanfattning : Stock options are priced numerically using space- and time-adaptive finite difference methods. European options on one and several underlying assets are considered. These are priced with adaptive numerical algorithms including a second order method and a more accurate method. LÄS MER

  4. 8. Anterior shoulder dislocation : Aspects of alternative methods of treatment and MR imaging

    Författare :Göran Wintzell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Shoulder; traumatic primary dislocation; arthroscopic lavage; non-operative regime; Indirect MR arthrography; apprehension position; ABER position; Bankart operation; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : Sixty patients (16-30 years) with traumatic primary anterior shoulder dislocation were allocated to arthroscopic lavage or non-operative treatment. The arthroscopic lavage group had a lower recurrence rate, better functional outcome and anterior stability after one year. LÄS MER

  5. 9. Towards low-emitting and sustainable particle and fibreboards : Formaldehyde emission test methods and adhesives from biorefinery lignins

    Författare :Venla Hemmilä; Stergios Adamopoulos; Luísa Maria Hora Carvalho; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Wood board industry; chamber methods; dynamic microchamber DMC ; bio-based adhesives; lignosulfonates; supercritical water hydrolyzed lignin; crosslinkers; fibreboards; particleboards; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : High volumes, fast production speed, and low material costs have been historically the driving factors of the particle- and fibreboard industries. However, in recent years the fossil-fuel dependency and health issues of the formaldehyde-containing adhesives used in the production have gained attention from both legislators and consumers.

  7. 10. Optimization Models and Methods for Telecommunication Networks using OSPF

    Författare :Peter Broström; Michal Pióro; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Telecommunication; OSPF; LP-duality; Polynomial methods; MATHEMATICS; MATEMATIK;

    Sammanfattning : The routing in OSPF Telecommunication networks is determined by computing shortest paths with respect to link weights set by the network operator. All shortest paths to a destination are used by the routers when traffic is routed, and the routers split the traffic evenly when alternative shortest paths exist. LÄS MER
