2. Determining the quality of natural gas and biomethane : Development of a correlative method and instrument prototype for measuring gas quality
Abstract : The composition of natural gas highly depends on its origin: natural gas from various deposits, substitute natural gas that can be produced from fossil fuels or renewable sources. The intermixing of gases from various supply sources during pipeline transportation also leads to more complicated and unpredictable gas composition variations at the consumption site. READ MORE

5. Sagittal synostosis - surgical outcomes and long-term follow up
Abstract : The overall aim of this thesis was to evaluate and compare surgical outcomes in patients with sagittal synostosis operated with the most commonly used surgical methods in Sweden: craniotomy combined with springs, pi-plasty, or H-craniectomy. Paper I is a systematic review that identified the evidence showing that spring-assisted surgery is as efficient as more extensive cranioplasties to be of very low quality, thereby emphasizing the need for more rigorous studies.
