  1. 1. Soft Tissue Aspects of the Shoulder Joint

    Författare :Shwan Khoschnau; Hans Rahme; Karl Michaelsson; Lars Adolfsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cruciate ligament; shoulder dislocation; polymorphism; collagen; biomechanical properties; rotator cuff tear; shoulder ultrasound; adhesive capsulitis; MRI;

    Sammanfattning : The aim of this thesis was to study different aspects of the soft tissues of the shoulder joint. The variation in the quality of the tendons and ligaments can be explained by genetic factors. LÄS MER

  3. 2. On the bone response to oxidized titanium implants. The role of microporous structure and chemical composition of the surface oxide in enhanced osseointegration

    Författare :Young-Taeg Sul; Göteborgs universitet; []
    Nyckelord :Oxidized titanium implants; micro arc oxidation; oxide growth; surface oxide properties; bone; biomechanical tests; histomorphometry; enzyme histochemistry.;

    Sammanfattning : Background: Titanium implants have been widely used clinically for various types of bone-anchored reconstructions. A thin native oxide film, naturally formed on titanium implants contacts with bone tissue and has been considered to be of great importance for successful osseointegration. LÄS MER

  4. 3. Geometric, biomechanical and molecular analyses of abdominal aortic aneurysm

    Författare :Moritz Lindquist Liljeqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Abdominal aortic aneurysm (AAA) is defined as a dilatation of the abdominal aorta of 30 mm in diameter or more. Main risk factors are smoking, age and male sex. Pathophysiological features include inflammation, smooth muscle cell loss and destruction of the extracellular matrix. LÄS MER

  5. 4. Biomechanical Analysis of Fall Injuries using Finite Element Modeling

    Författare :Pooya Sahandifar; Svein Kleiven; Viveca Wallqvist; Yunhua Luo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fall induced injury; finite element analysis; rubberized asphalt mixture; shock-absorbing pavement; hip fracture; elderly; sideways fall; whole-body model;

    Sammanfattning : A fall is a serious health issue for the elderly. Among different fall types, the sideways fall is considered to be more severe concerning the injury outcome. LÄS MER

  7. 5. Computational Modeling of the Vocal Tract : Applications to Speech Production

    Författare :Saeed Dabbaghchian; Olov Engwall; Sidney Fels; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vocal tract; upper airway; speech production; biomechanical model; acoustic model; vocal tract reconstruction; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : Human speech production is a complex process, involving neuromuscular control signals, the effects of articulators' biomechanical properties and acoustic wave propagation in a vocal tract tube of intricate shape. Modeling these phenomena may play an important role in advancing our understanding of the involved mechanisms, and may also have future medical applications, e. LÄS MER
