11. Virtue Ethics, Bioethics, and the Ownership of Biological Material
Sammanfattning : The overall aim of this thesis is to show how some ideas in Aristotle’s Nicomachean Ethics can be interpreted and used as a productive way to approach a number of pressing issues in bioethics. Articles I-II introduce, and endorse, a social constructivist perspective on rights (as opposed to the more traditional natural rights idea). LÄS MER

13. Biomolecule Trapping With Stimuli-Responsive Polymer Coated Nanostructures
Sammanfattning : Trapping biomolecules in nanosized gaps is of great interest in novel systems for single molecule analysis and membranes, which filter biomolecules. Current platforms are lacking in full functionality to facilitate biomolecule trapping and transport in their native environment and without covalent tethering to surfaces. LÄS MER
14. Aspects of Porous Graphitic Carbon as Packing Material in Capillary Liquid Chromatography
Sammanfattning : In this thesis, porous graphitic carbon (PGC) has been used as packing material in packed capillary liquid chromatography. The unique chromatographic properties of PGC has been studied in some detail and applied to different analytical challenges using both electrospray ionization-mass spectrometry (ESI-MS) and ultra violet (UV) absorbance detection.

15. Ecology across Boundaries : Food web coupling among and within ecosystems
Sammanfattning : Cross-boundary movements of energy and material are ubiquitous. Freshwater ecosystems receive nutrients, dissolved, and particulate organic matter from adjacent terrestrial ecosystems, whereas terrestrial ecosystems mainly receive prey organisms and detritus deposited by physical processes such as floods from freshwater ecosystems.
