1. Med livet på schemat : om skolämnet livskunskap och den riskfyllda barndomen
Sammanfattning : Skolämnet livskunskap har vuxit fram i svenska skolor under det senaste decenniet, ofta utifrån en ambition att främja hälsa och att konkretisera skolans värdegrundsarbete. Mot bakgrunden att livskunskap inte är obligatoriskt i svensk skola och därför saknar nationella riktlinjer har ämnet i den lokala skolpraktiken kommit att omfattas av en mängd olika arbetssätt och program.

2. Scattering Studies of Macromolecules in Solution
Sammanfattning : The sphere-to-rod transition of nonionic micelles of the PEO-PPO-PEO triblock copolymer P123 and the surfactant C12EO6 was studied using dynamic and static light scattering, small angel X-ray scattering, rheology and calorimetry. The transition temperature was dependent of the C12EO6/P123 molar ratio, which means that a larger content of C12EO6 yields a higher transition temperature. LÄS MER
3. Epidemiological studies of reproductive performance indicators in Swedish dairy cows
Sammanfattning : Reproductive efficiency in dairy cows is a key factor for milk producers, and numerous studies have identified impaired reproductive performance as a major cause of reduced production efficiency in the dairy industry. The overall aim of this thesis was to gain knowledge of factors affecting the reproductive performance indicators currently used by herd advisory services and to find other, possibly more efficient, ways to measure reproductive performance in dairy cows.

4. Parallelizing the Method of Conjugate Gradients for Shared Memory Architectures
Sammanfattning : Solving Partial Differential Equations (PDEs) is an important problem in many fields of science and engineering. For most real-world problems modeled by PDEs, we can only approximate the solution using numerical methods. Many of these numerical methods result in very large systems of linear equations. LÄS MER
