Sammanfattning : Bacterial chromosomes are highly dynamic, continuously changing with respect to gene content and size via a number of processes, including deletions that result in gene loss. How deletions form and at what rates has been the focus of this thesis. In paper II we investigated how chromosomal location affects chromosomal deletion rates in S. LÄS MER
3. Investigations of species richness effects on ecosystem functioning using stream-living macroinvertebrates as model organismsDetta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : The work in this thesis deals with effects of changed species richness on process rates among stream-living macroinvertebrates. Global biodiversity is decreasing rapidly and it is poorly known what the consequences of this loss may be for ecosystems and the services they provide. LÄS MER

Sammanfattning : Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. LÄS MER
5. Service Life Assessment of Harbor Structures - Case studies of chloride ingress into concrete and sheet piling corrosion ratesDetta är en avhandling från Division of Building Materials, LTH, Lund University
Sammanfattning : Popular Abstract in English The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where most steel sheet pile walls have cap beams of reinforced concrete. LÄS MER
