1. 11. Mathematical Modeling of the Muscle Effects on the Human Body Responses under Transient Loads - Example of the Head-Neck Complex

   Författare :Adam Wittek; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cervical spine; transient loads; muscle effects; Hill-type muscle models; finite element analysis; impact biomechanics; mathematical modeling;

   Sammanfattning : The goal of this study was to develop and apply a method that overcomes limitations of the currently available solutions for finite-element modeling of skeletal muscles and their effects on dynamic responses of the human body under transient loads. One of such limitations is that finite element codes commercially available in the field impact biomechanics do not contain any specific procedures for simulation of skeletal muscles. LÄS MER

3. 12. Biochemical and biomechanical modulation of the in vitro retina

   Författare :Linnéa Taylor; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retina; in vitro; modulation; biomechanics; glutamate; GDNF; stretch; Müller cells; Photoreceptors; gliosis;

   Sammanfattning : The porcine retinal explant culture paradigm offers the possibility to study retinal health, disease and development independently from the surrounding tissues of the eye. Retina-intrinsic effects of molecular and mechanical cues on the isolated retinal sheet can thus be studied with great precision. LÄS MER

4. 13. Brain injury biomechanics in closed-head impact : studies on injury epidemiology, tolerance criteria, biomechanics and traffic injury prevention

   Författare :David Viano; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Closed-head impact; brain injury; biomechanics; injury mechanisms; tolerance criteria; epidemiology; and primary prevention.;

   Sammanfattning : Permanent disability from traumatic brain injury is a devastating consequence of traffic crashes. Injury prevention is a fruitful approach to reduce the incidence and severity of disabling brain injury. LÄS MER

5. 14. Acute Achilles tendon rupture - The impact of calf muscle performance on function and recovery

   Författare :Annelie Brorsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Achilles tendon rupture; Rehabilitation; Heel-rise; Function; Recovery; Calf muscle; Ankle biomechanics; Endurance; Jump; Sex differences;

   Sammanfattning : There is an ongoing debate about the optimal treatment for patients with an acute Achilles tendon rupture. The overall purpose of this thesis was to acquire a greater knowledge of the way patients recover at different time points after the injury when treated with the currently recommended treatment protocols.

7. 15. Neck-Injuries in Rear-End Car Collisions: Sites and Biomechanical Causes of the Injuries, Test Methods and Preventive Measures

   Författare :Mats Svensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The present work addresses the problem of neck injuries following rear-end car collisions. Biomechanics and sites of the injuries have been investigated. A new dummy neck has been developed and used to study the influence of different seat properties on occupant kinematics. LÄS MER
