Studies of the Arctic Ocean sea ice cover and hydrothermal heat fluxes
(2012-10-26)Since reliable ice extent estimates from satellite data became available in 1979 the Arctic sea ice cover has followed a declining long term trend. Over the last decade the decline has accelerated with record low sea ice ... -
Detoxification Mechanisms in Fish - Regulation and function of biotransformation and efflux in fish exposed to pharmaceuticals and other pollutants
(2012-10-26)It is likely that fish in their natural environment are exposed to mixtures of several pharmaceuticals as well as other pollutants. This may result in adverse effects which are augmented due to the chemical interactions. ... -
Selectivity of dopamine D1 and D2 receptor agonists – A combined computational approach
(2012-10-26)Dopamine (DA) is an endogenous neurotransmitter acting in the central nervous system. DA plays a key role in many vital brain functions such as behavior, cognition, motor activity, learning, and reward. Dopamine receptors ... -
Formation and Distribution of Marine Biogenic Halocarbons with Emphasis on Polar Regions
(2012-10-19)It is well-established that marine micro- and macroalgae form volatile halogenated compounds (halocarbons). Production occurs throughout the world ocean with strong regional sources in coastal areas. In the atmosphere, ... -
Attenuation of acute inlammatory responses by surface nanotopography
(2012-10-04)The interaction between biology and non-viable surfaces is crucial for many organisms and cells. For example, bacterial cells need to adhere to mineral surfaces in the soil, plants climb and adhere to walls and marine ... -
Design, Synthesis, and Evaluation of Functionalized Chroman-4-one and Chromone Derivatives. Somatostatin receptor agonists and Sirt2 inhibitors
(2012-10-04)Peptides are involved in many physiological processes such as regulation of blood-pressure, food intake, pain transmission and blood-glucose levels. They consist of amino acids that are connected through amide bonds which ... -
Bonadsmåleri under lupp: Spektroskopiska analyser av färg och teknik i sydsvenska bonadsmålningar 1700-1870
(2012-10-02)The objects of this PhD thesis are Southern Swedish painted wall-hangings: folk art paintings from the 18th and 19th centuries. The aim and objective of the study are: to investigate the construction and manufacturing ... -
Proceedings of the 2nd Workshop on Experiences and Empirical Studies in Software Modelling
(2012-09-28)The International Workshop on Experiences and Empirical Studies in Software Modelling (EESSMod) is a satellite event of the ACM/IEEE International Conference on Model Driven Engineering Languages and Systems (MoDELS), ... -
Interaction and disorder in helical conductors
(2012-09-28)Different effects from electron-electron interactions and disorder in helical and quasi-helical conductors are studied using bosonisation and renormalisation group methods. The combined effects of Rashba spin-orbit ... -
Structural Insights at Sub-Ångstrom, Medium and Low Resolution: Crystallization of Trypsin, Bacterioferritin, Photosynthetic Reaction Center, and Photosynthetic Core Complex
(2012-09-28)The catalytic action of serine proteases depends on the interplay of a nucleophile, a general base and a general acid. The catalytic triad is composed of serine, histidine and aspartate residues. The serine acts as a ... -
Grazer-induced responses in marine phytoplankton
(2012-09-27)Phytoplankton are the most important primary producers in the world’s oceans, yet little is known of how they avoid the constant threats from the pelagic grazers. From land it is well known that plants defend themselves ... -
Space-Safe Transformations and Usage Analysis for Call-by-Need Languages
(2001)This thesis is concerned with the resource consumption of lazy functional languages. It touches upon two aspects: how to reason about the space-safety of program transformations, and how to apply usage analysis for compiler ... -
Cold-climate landforms on Mars and Earth-analogues in Svalbard
(2012-09-14)Periglacial landforms on Earth reflect cold-climate conditions and are intimately related to processes due to the presence of ground ice and perennially frozen ground, permafrost. The overall objective of this thesis is ... -
Plant Species Composition and Diversity in Cliff and Mountain Ecosystems
(2012-09-12)Ecosystems today are under increasing pressure from a rapidly changing climate, changes in land-use, habitat fragmentation and degradation and increasing anthropogenic disturbance. Studying drivers of biodiversity patterns ... -
Negotiating ‘Culture’, Assembling a Past: the Visual, the Non-Visual and the Voice of the Silent Actant
(2012-09-12)The aim of this thesis is to describe and analyse the processes surrounding the creation of a scientific visual representation, where, both in the practical creation of this visualisation and in the way it is communicated, ... -
Towards Formalizing Assumptions on Architectural Level: A Proof-of-Concept
(Departmen of Computer Science and Engineering, 2012-09-10)While designing an architecture, architects often make assumptions about different factors like execution environment, structural properties of the artifacts, properties of input/output data etc. Implicit and invalid ... -
Iron or Copper? - Method Development and Mechanistic Studies on Cross-Coupling Reactions
(2012-09-06)The area of catalysis has had an immeasurable impact on modern society. This has been acknowledged through several Nobel prizes during the 20th century ranging from Haber (1918) for the synthesis of ammonia to Richard ... -
Phylogenetic Inference and Allopolyploid Speciation - A Study of Silene section Physolychnis
(2012-08-31)The major theme of this thesis is allopolyploidization, with focus on Silene section Physolychnis. The evolutionary history of an allopolyploid species can be established by inferring the sister relationships of the ... -
Cellular Resilience and Fragility in Response to Environmental and Gene Expression Perturbations
(2012-08-30)Cells are constantly subjected to perturbations. Whether these are extracellular or intracellular, they can be detrimental to cellular fitness. The cell has evolved elaborate systems and mechanisms that allow it to remain ... -
En timmermans teorier om timring
