The influence of climate on ozone risk for vegetation
(2011-05-11)Ground-level ozone (O3) is a harmful air pollutant causing reduced crop yield and quality, reduced forest growth and negative effects on human health in large parts of the world. O3 is generally seen as a regional scale ... -
Regulation of electron donation to photosystem 1
(2011-05-09)Photosynthesis is the process where energy from light is used to catalyze the formation of energy-rich molecules such as NADPH and ATP. These reactions are in fact the result of a long series of electron-transfer reactions ... -
Management of urban woodlands - effects on bird communities and recreational values
(2011-05-07)The ongoing urbanisation increases the pressure on urban nature. Urban woodlands are receiving growing attention as they provide valuable ecosystem services to urban citizens, mainly by providing areas for recreation but ... -
Urban Climate and Air Pollution in Ouagadougou, Burkina Faso
(2011-05-05)ABSTRACT Africa has recently been singled out by UN Habitat as the fastest urbanizing continent in the world. The most extreme case was found in the Sahelian city of Ouagadougou, Burkina Faso, where the population is ... -
AQUAPORINS: Production Optimization and Characterization
(2011-05-05)Aquaporins are water facilitating proteins embedded in the cellular membranes. Such channels have been identified in almost every living organism – including humans. They are vital molecules and their malfunction can lead ... -
Alien Fish Species in the Eastern Mediterranean Sea: Invasion Biology in Coastal Ecosystems
(2011-04-25)The spread of non-indigenous species (NIS) in the eastern Mediterranean Sea is an ongoing and accelerating process. Non-indigenous species are regularly reported from various coastal habitats in the eastern Mediterranean ... -
Systematics of Marionina (Annelida: Clitellata: Enchytraeidae)
(2011-04-25)This thesis is about species of segmented worms that previously were placed in the genus Marionina Michaelsen, 1890, within the family Enchytraeidae, class Clitellata and phylum Annelida. These species are closely related ... -
Absolute Asymmetric Synthesis
(2011-04-18)Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of ... -
Environmental and health hazards of chemicals in plastic polymers and products
(2011-04-15)Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has ... -
Ädelputs
(Hantverkslaboratoriet, Göteborgs universitet, 2011)Ädelputsen som introducerades under 1900-talets början hör till det moderna byggandet. Man har använt olika verktyg och hantverkstekniker, vilka präglar putsernas och arkitekturens uttryck. Man har också använt olika ... -
Homochiral Crystals for Selective Synthesis
(2011-04-13)Six new coordination compounds were prepared from monodentate sulfide ligands and copper(I) halides and their crystal structures were determined by single-crystal X-ray diffraction. The aim was to prepare coordination polymers ... -
The Importance of a Fifth Element in Transcription: Transcriptional Discrimination in Escherichia coli
(2011-04-08)Upon growth arrest of the bacterium Escherichia coli, RNA polymerase (Es70) is redirected from transcribing genes encoding the protein synthesizing system (PSS) to those involved in maintenance and stress resistance. The ... -
Seals and fisheries: a study of the conflict and some possible solutions
(2011-04-08)Interaction between seals and fisheries along the Swedish coast has serious environmental and economic consequences. This thesis describes the conflict as it affects four different small-scale coastal fisheries; the eel ... -
Index theory in geometry and physics
(2011-04-06)This thesis contains three papers in the area of index theory and its applications in geometry and mathematical physics. These papers deal with the problems of calculating the charge deficiency on the Landau levels and ... -
Structure and Function of Aqua(glycero)porins - A Path to Drug Design
(2011-04-05)Membrane proteins are a major class of the drug targets. Rational design of drugs requires knowledge about the structure and function of these proteins. Working with membrane proteins, however, is experimentally challenging ... -
Algorithms for analysis of NMR projections: Design, implementation and applications
(2011-03-29)With an increasing rate of protein expressions the need for fast protein characterization has become more important. Protein NMR has long been an important contributor for protein characterization; being one of a few ... -
Mesoscopic phenomena in the electromechanics of suspended nanowires
(2011-03-25)Over the last two decades nanotechnology has been a very active field of scientific research, both from fundamental perspectives as well as for applications in technology and consumer goods. In this thesis, theoretical ... -
Post-transcriptional regulation after stress in Schizosaccharomyces pombe
(2011-03-18)Post transcriptional regulation is part of the gene expression control and is important for many cellular processes. It influences how mRNAs are selected for translation, degradation or storage. In this thesis, I describe ... -
