1. Thermodynamics and Kinetics in Metallurgical Processes - with a Special Focus on Bubble Dynamics
Sammanfattning : Gas stirring is commonly used in the steelmaking processes to reinforce chemical reactions, kinetic transfer, and inclusion removal, etc. This dissertation concentrates on multiphase flows with gas bubbling to study fluid dynamics and thermodynamics in metallurgical processes.

2. Framåtsyftande bedömning i tidig läsundervisning : Teori och praktik
Sammanfattning : Syfte är att bidra med kunskap om hur framåtsyftande bedömning kan användas och används av lärare som underlag för pedagogiska åtgärder i tidig läsundervisning. I avhandlingen har jag ett pragmatiskt förhållningssätt till både teorier och metoder. Avhandlingen bygger på fyra artiklar. LÄS MER
3. Local Conditions for Long Cycles in Graphs
Sammanfattning : A Hamilton cycle in a graph is a cycle that passes through every vertex of the graph. A graph is called Hamiltonian if it contains such a cycle. The problem of determining if a graph is Hamiltonian has been studied extensively, and there are many known sufficient conditions both for Hamiltonicity and for other, related properties. LÄS MER
4. Quality in Learning in Rwandan Higher Education : Different stakeholders’ perceptions of students’ learning and employability
Sammanfattning : The aim of the thesis is to investigate quality in learning in higher education in Rwanda by focusing on students’ learning and their employability. This focus allows for an understanding of key challenges for Rwandan higher education to emerge, at a time when more and more students are enrolling. LÄS MER
5. Engineered ion-bombardment as a tool in thin film deposition
Sammanfattning : Energetic-ion bombardment has become an attractive route to modify the crystal growth and deposit high quality thin films. In high-power impulse magnetron sputtering (HiPIMS) where the discharge is characterized by a significant amount of ions of the sputter-ejected atoms, energetic-ion bombardment effects could not be underestimated.
