Sammanfattning : A deterministic approach based on a modal expansion and modal receptance method has been developed to evaluate the airborne sound insulation of aircraft panels with stringer and ring frame attachments. Furthermore, this method was extended to predict the noise radiation of stiffening panel subjected to TBL excitation. LÄS MER

Sammanfattning : ABSTRACTAlthough it is well known that fibre reinforcement acts as a crack arresting agent, there is still a need for deeper knowledge of the actual cracking behaviour, especially regarding cracks with widths smaller than 0.3mm. LÄS MER
Sammanfattning : Cardiovascular disease is a leading cause of morbidity and mortality worldwide. A large number of studies show that the risk of cardiovascular disease is increased in people born with low birth weight. LÄS MER
5. Epidemiological, mechanistic and genetic aspects of vascular ageing and arterial stiffness in the population
Sammanfattning : The core feature of vascular ageing is the age-associated stiffening of the large, elastic arteries, or arteriosclerosis. This results in a diminished volume-buffering function and is therefore central for the increase in systolic blood pressure and pulse pressure seen with advancing age. LÄS MER
