Sammanfattning : A main aspect of wellbore stability analysis is the selection of an appropriate rock failure criterion. The most commonly used criterion for brittle failure of rocks is the Mohr-Coulomb criterion. LÄS MER
Sammanfattning : With more people flying every year, new technologies are needed to reduce our impact on the environment. One option is to reduce the energy used in flight by introducing lighter materials such as carbon fibre reinforced polymers (CFRP). LÄS MER
3. Bridging the gap between clinical trials and clinical practice : sacubitril-valsartan in heart failure as a model
Sammanfattning : When novel treatments prove more effective than standard therapies, a swift and effective implementation is needed to reach cost-effectiveness and to benefit eligible patients. Meanwhile, women and elderly are often under-represented in clinical trials, which creates a knowledge gap on how to optimize treatment in clinical practice. LÄS MER
Sammanfattning : Background: Heart failure (HF) is a major health problem worldwide with exponentially increasing incidence with age and the majority of patients being elderly. In recent years, an increase in hospitalization and prevalence of HF in younger persons has been documented in Sweden and Denmark, in contrast to an overall decrease in older patients. LÄS MER
Sammanfattning : In this doctoral thesis work the relationship between the deformation and the initiation of failure around an underground excavation was studied. In this work data from observed failure and measured deformations was used. This work is based on information obtained from laboratory test, underground field cases and numerical analysis. LÄS MER
