1. The role of microclimate for the performance and distribution of forest plants
Sammanfattning : Microclimatic gradients may have large influence on individual vital rates and population growth rates of species, and limit their distributions. Therefore, I focused on the influence of microclimate on individual performance and distribution of species. LÄS MER
2. A numerical and experimental investifgation on surface and sub-surface initiation of contact fatigue cracks at cylindrical contacts
Sammanfattning : .... LÄS MER
3. Parents, Children and Childbearing
Sammanfattning : This doctoral thesis provides a set of studies of social influences on fertility timing. Swedish register data are used to link individuals to their parents and siblings, thereby allowing the study of impacts of family of origin, social background, and parental death on fertility.

4. Genetic Cartography at Massively Parallel Scale
Sammanfattning : Massively parallel sequencing (MPS) is revolutionizing genomics. In this work we use, refine, and develop new tools for the discipline.MPS has led to the discovery of multiple novel subtypes in Acute Lymphoblastic Leukemia (ALL). In Study I we screen for fusion genes in 134 pediatric ALL patients, including patients without an assigned subtype. LÄS MER
5. On the asperity point load mechanism for rolling contact fatigue
Sammanfattning : Rolling contact fatigue is a damage process that may arise in mechanical applications with repeated rolling contacts. Some examples are: gears; cams; bearings; rail/wheel contacts. The resulting damage is often visible with the naked eye as millimeter sized surface craters. LÄS MER
