  1. 16. Anchorage of naturally-corroded, plain bars in Reinforced Concrete structures

    Författare :Samanta Robuschi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bond; corrosion; concrete; anchorage; plain reinforcement bars;

    Sammanfattning : Reinforced Concrete (RC) is the most common construction material in existing structures. However, RC structures are susceptible to deterioration over time, with corrosion of the reinforcing steel as most common mechanism. Corrosion reduces strength and ductility provided by the reinforcement bars and affects their interaction with the concrete. LÄS MER

  3. 17. On costochondral grafts replacing mandibular condyles in juvenile chronic arthritis. A clinical, histological and experimental study

    Författare :Börje Svensson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; juvenile chronic arthritis; temporomandibular joints; temporomandibular disorders; costochondral grafts; growth; revascularisation; microangiography; fluorochrome labelling.;

    Sammanfattning : In children with juvenile chronic arthritis (JCA), disturbances of mandibular growth and function may result in involvement of the temporomandibular joints (TMJs). The aim of this thesis was to study the stomatognathic system in JCA children and long-term effects on facial growth of treatment comprising replacement of arthritic mandibular condyles with autogenous costochondral grafts (CCGs) during growth.

  4. 18. Human Body Model Morphing for Assessment of Crash Rib Fracture Risk for the Population of Car Occupants

    Författare :Karl-Johan Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; crash; human body model; morphing; SAFER HBM; rib fracture risk; vehicle safety;

    Sammanfattning : Fractured ribs are prevalent injury outcomes for vehicle occupants involved in crashes. Sex, age, and anthropometry of an occupant influences the risk to sustain rib fractures. LÄS MER

  5. 19. Comparative study of Radiation Therapy of Targets in the Upper Abdomen with Photon- or Scanned Proton-beams

    Författare :Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photon radiotherapy; proton beam radiotherapy; gastric cancer; liver metastases; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : Recently, there has been an increase in the number of proton beam therapy (PBT) centers operating worldwide. For certain cases, proton beams have been shown to provide dosimetric and radiobiological advantages when used for cancer treatment, compared to the regular photon-beam based treatments. LÄS MER

  7. 20. Novel skeletal stem and progenitor cells and their regulation

    Författare :Baoyi Zhou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The development of bone and cartilage, which provide the framework of the skeletal system, is complex. In this context stem and progenitor cells play a crucial role by producing differentiated cells. Hormones are important regulators of this process, with growth hormone (GH) acting as the major endocrine regulator of longitudinal bone growth. LÄS MER
