16. Dynamic response reconstruction using passive components
Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER
17. Carbohydrate and metabonomic studies by NMR spectroscopy
Sammanfattning : NMR spectroscopy can be used to investigate organic and biomolecular structures, both as pure compounds and in complex mixtures. In this thesis NMR spectroscopy was used for carbohydrate and metabonomic studies. LÄS MER
18. Exploring Unorthodox Aquaporins : Characterization of NbXIPs & AtNIPs
Sammanfattning : AbstractAquaporins are membrane integral proteins that facilitate the transport of waterand/or other small neutral molecules across biological membranes in cells in allforms of life. Among the subfamilies of aquaporins in higher plants, the X IntrinsicProteins (XIPs) are the most recently discovered subfamily and the leastcharacterized. LÄS MER
19. Thiopurine S-methyltransferase - characterization of variants and ligand binding
Sammanfattning : Thiopurine S-methyltransferase (TPMT) belongs to the Class I S-adenosylmethionine-dependent methyltransferase (SAM-MT) super family of structurally related proteins. Common to the members of this large protein family is the catalysis of methylation reactions using S-adenosylmethionine (SAM) as a methyl group donor, although SAM-MTs act on a wide range of different substrates and carry out numerous biologically important functions.

20. Functional and structural characterizations of phytoplankton-bacteria interactions in response to environmental challenges
Sammanfattning : Microorganisms, such as phytoplankton and bacteria, make up ≈70% of aquatic biomass and contribute 50-85% of the oxygen in Earth’s atmosphere. The microbial loop concept and the discovery of the large diversity in microbial communities acknowledge that biotic interactions between microorganisms in addition to resource competition enable the recycling of energy and nutrients in aquatic food webs.
