  1. 1. Stability of aligned maxillary anterior teeth after orthodontic treatment : amount of changes with different retention methods and without retention

    Författare :Sasan Naraghi; Vaska Vandevska-Radunovich; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Well-aligned anterior teeth are the major reason for the patients seeking orthodontic treatment, and keeping teeth aligned and stable afterwards is a goal for the orthodontist and the patient. Relapse after treatment is a common problem, and it is defined as when teeth go back to their previous positions. LÄS MER

    Sammanfattning : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. LÄS MER

  4. 3. What’s in a name? : Sub-fractionation of common lymphoid progenitors

    Författare :Sasan Zandi; Mikael Sigvardsson; Avinash Bhandoola; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The hematopoietic system is a highly dynamic organ developed in many multi-cellular organisms to provide oxygen, prevent bleeding and to protect against microorganisms. The blood consist of many different specialized cells that all derive from rare hematopoietic stem cells (HSCs) located in the bone marrow in mice and humans. LÄS MER

  5. 4. High quality frequency modulated halftoning

    Författare :Sasan Gooran; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The fact that most printing devices, such as laser printers, are restricted to very few colors has led to an increased interest in finding efficient techniques that transform a continuoustone image into a binary one. Such techniques are referred to as halftoning methods. LÄS MER

  7. 5. Numerical study on instability and interaction of wind turbine wakes

    Författare :Sasan Sarmast; Dan. S. Henningson; Per-Åge Krogstad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind turbine wakes; Stability; interaction; POD; DMD; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Numerical simulations of the Navier-Stokes equations are conducted to achieve a better understanding of the behavior of wakes generated by the wind turbines. The simulations are performed by combining the in-house developed code EllipSys3D with the actuator line technique. LÄS MER
