16. Alternative NAD(P)H dehydrogenases in plant mitochondria - localisation, catalytic functions and physiological roles
Sammanfattning : In addition to complex I, the plant mitochondrial electron transport chain possesses several alternative NAD(P)H dehydrogenases, not present in animals. These enzymes allow nonenergy-conserving electron transfer from cytoplasmic and matrix NAD(P)H to ubiquinone. LÄS MER
17. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases
Sammanfattning : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. LÄS MER
18. A Play of Light and Spins: Excitation and Detection of Non-linear Magnetization Dynamics using Light
Sammanfattning : The excitation and detection of magnetization dynamics play key roles in the field of spintronics and magnonics. In this thesis, we investigate a contactless method of exciting nonlinear magnetization dynamics using a femtosecond pulsed laser, and study the same with a Brillouin Light Scattering (BLS) microscope.

19. Nonionic Microemulsions: Dependence on Oil Chain Length of the Surfactant Curvature Elastic Properties
Sammanfattning : The aim with this thesis has been to increase the knowledge about nonionic microemulsions and how they behave with increasing temperature. I have studied Nonionic Microemulsions made from C12E5, water and oil, with predominally hexadecane as oil, but also with octane, decane, dodecane and tetradecane as oil. LÄS MER
20. Light scattering in pulp and paper
Sammanfattning : The pulp and paper industry of today is facing a highly competitive market where manufacturers are constantly seeking ways to reduce costs as well as to improve product specifications and quality. On-line quality control is one of many areas being actively developed, from the wood delivered to the plant to the fibers in the finished product. LÄS MER
