Spectral properties of elliptic operators in singular settings and applications
(2019-05-22)The present thesis is focused on the investigation of the spectral properties of the linear elliptic operators in the presence of singularities. It is divided into three chapters. In the first chapter, we consider ... -
Production and Structural Dynamics of Microbial Rhodopsins
(2019-05-22)Rhodopsins are a family of membrane proteins that are found in a wide range of organisms and provide them with the ability to sense and react to light. When light is absorbed by these proteins, structural changes occur ... -
Double Inner-Shell Vacancies in Molecules
(2019-05-15)Molecular electronic states possessing a double core-vacancy, referred to as double-core-hole (DCH) states, were predicted more than thirty years ago, to have interesting properties, which would allow one to probe matter ... -
Multi-electron processes in atoms and molecules - Experimental investigations by coincidence spectroscopy
(2019-05-15)This thesis presents studies on multi-electron processes in atoms and molecules initiated by single-photon absorption. The experimental techniques used for these studies rely on synchrotron radiation offered at large scale ... -
Multi-Electron and Multi-Ion Coincidence Spectroscopy of Single-Photon Ionization Processes in Molecules
(2019-05-15)This thesis presents experimental investigations of multi-electron and multi-electron-multi-ion coincidence measurements of samples in the gas phase utilizing a versatile time-of-flight magnetic bottle spectrometer technique. ... -
Heathlands – A Lost World?
(2019-05-03)Heathland is a familiar landscape type in southwest Sweden. It is open with few trees, and the vegetation is dominated by dwarf-shrubs growing on nutrient-poor soils. Dry heaths with Heather Calluna vulgaris and wet heaths ... -
Polyploid Phylogenetics in Plants: Insights on non-model organisms in Fabaceae and Malvaceae
(2019-05-02)Genome duplication is a common phenomenon in angiosperms and advances in sequencing technologies and bioinformatics is now revealing its prevalence and significance. In a polyploidization event all genes in a genome are ... -
Microplastics in the aquatic environment: Insights into biological fate and effects in fish
(2019-03-26)According to the United Nations, plastic pollution in the natural environment has been identified as one of the biggest environmental challenges of this century and has become a cause for an emerging international concern. ... -
Structural and Interaction Studies of the Human Protein Survivin.
(2019-03-14)Cell division and cell death (apoptosis) are two essential processes to maintain the specific number of cells in all multicellular organisms. In humans, the misregulation of these processes leads to severe diseases, such ... -
Secondary Organic Aerosols: Composition, Gas-to-Particle Partitioning and Physical Properties
(2019-02-21)Atmospheric aerosols influence our climate and air quality. Aerosol particles in the atmosphere are transformed through many different physical and chemical reactions. A substantial fraction of the particles in the ... -
Kalkbruk - krympsprickor och historisk utveckling av material, metoder och förhållningsätt
(2019-01-31)I denna avhandling undersöks uppkomst av krympsprickor i puts. I undersökningen används våtsläckt sub- hydrauliska kalk. Den aktuella kalksorten har används i Sverige under 1800- och 1900-talet men också under 2000-talet ... -
I sökandet efter delaktighet. Praktik, aktörer och kulturmiljöarbete.
(2019-01-17)This dissertation concerns national heritage management as it is performed as an established institutional practice and a politically defined engagement. Since the late 1990´s an overarching political objective has been ... -
Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation
(2019-01-15)The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere ... -
Structure-Specific Vibrational Modes of Isolated Biomolecules Studied with Mid- and Far-Infrared Laser Spectroscopy
(2019-01-14)Biomolecular structure elucidation is crucial for our detailed understanding of various biological processes, since there is an intimate relationship between the biomolecular function and structure. In this respect, isolated ... -
Structural and Functional Studies of Membrane Proteins For Future Development of Antimicrobial Drugs
(2019-01-10)Antibiotic resistance is a world-wide occurring problem which threatens human health. Without development of any new and effective antibiotics, the rapid growth of antibiotic-resistant bacterial infections could put society ... -
Gräsbränning på Motala äng
