1. Modelling of Diffuse Brain Injury: Combining Methods to Study Possible Links between Transient Intracranial Pressure and Injury
Sammanfattning : The objectives of this research are the study of sagittal rotational acceleration induced diffuse brain injury mechanisms. Such injuries are common in vehicle accidents in particular; the consequences range from mild to severe symptoms and may lead to persistent neurological dysfunction. LÄS MER
2. Assessment of experimental neurotrauma
Sammanfattning : Model systems of closed head injury are designed to replicate aspects of traumatic brain injury, ischemia and epilepsy in man. The aim of this thesis was to (1) develop sensitive systems enabling analyses of the biochemical reactions, as reflected by leakage of marker compounds to the cerebrospinal fluid (CSF); and (2) develop and assess a new model for closed head injury and associated dynamic changes in the brain cell.

3. Physical Modeling of Brain and Head Kinematics
Sammanfattning : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. LÄS MER
4. Methods for Control of Liquid Slosh
Sammanfattning : Horizontal movement of liquid containers is a common operation in an industrial packaging machine. During the movement the acceleration of the container induces motion of the liquid within the container, this is referred to as liquid slosh or liquid vibration. LÄS MER
5. Brain injury biomechanics in closed-head impact : studies on injury epidemiology, tolerance criteria, biomechanics and traffic injury 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
