Forest and land use mitigation and adaptation in Sri Lanka – Aspects in the light of international climate change policies
(2012-03-05)As a developing island nation, Sri Lanka is vulnerable to the possible impacts of climate change. The land use and forestry sector accounts for a large part of Sri Lanka’s greenhouse gas emissions and can play a major ... -
Lärares formande av en yrkesidentitet relaterad till hållbar utveckling
(2011)Swedish schools are required to educate for sustainable development (ESD). The challenges for the teachers are demanding as the content is controversial and complex. This study focuses on exploring the different ways ... -
Assessment of dietary patterns and prey consumption of marine mammals: Grey seals (Halichoerus grypus) in the Baltic Sea
(2012-02-09)The Baltic Sea has been severely affected by pollution and resource overexploitation during the last centuries. The grey seal (Halichoerus grypus) is a good example of how a species can be affected by such changes. In the ... -
Thermal properties of clusters and molecules - Experiments on evaporation, thermionic emission, and radiative cooling
(2012-02-03)This thesis presents experiments performed on clusters and molecules, where the three channels of unimolecular decay have been studied. Evaporation from protonated and negatively charged water cluster have yielded size ... -
Design and Synthesis of Chalcone and Chromone Derivatives as Novel Anticancer Agents
(2012-01-23)This thesis comprises the design and synthesis of chalcone and chromone derivatives and their use in various biological applications, particularly as anticancer agents (targeting proteins associated with cancer pathogenesis) ... -

Symmetry of Halonium Complexes in Solution
(2012-01-13)In this thesis the symmetry of two interaction types involving electropositive halogens have been studied in solution; the N-X+-N halogen bond (X = Br or I), and the C-X+-C interaction of previously characterised, cyclic, ... -
Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution
(2012-01-12)Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic ... -
Byggnaden som kunskapskälla
(2012-01-10)Buildings are indeed mute, yet many historians and architects claim that they can nevertheless speak. The challenge is to understand their language. This thesis examines the building as a source of knowledge. Setting out ... -
Nanoelectromechanical systems from carbon nanotubes and graphene
(2012-01-02)Carbon nanotubes and graphene have many interesting properties. To exploit the properties in applications their synthesis and incorporation in devices has to be understood and controlled. This thesis is based on experimental ... -
MECHANISTIC INVESTIGATIONS OF TRANSITION METAL CATALYZED REACTIONS
(2011-12-14)Transition metal catalyzed reactions have had a large impact on the human progress for the last century. Several extremely important areas, such as the agricultural industry and the plastic industry, have benefited from ... -
Chiral Lithium N,P-amide Complexes. Synthesis, Applications and Structural Studies by NMR and DFT.
(2011-11-28)Enantiospecific synthesis reactions are of intense interest, owing to the increasing request for enantiopure compounds in both research and industry. Lithium amides containing a secondary chelating group are a class of ... -
Percolation: Inference and Applications in Hydrology
(2011-11-25)Percolation theory is a branch of probability theory describing connectedness in a stochastic network. The connectedness of a percolation process is governed by a few, typically one or two, parameters. A central theme ... -
Influence of resuspension on sediment-water solute exchange and particle transport in marine environments
(2011-11-24)Marine sediments contain a large pool of nutrients, which if released would contribute to increased eutrophication, in spite of decreased nutrient loads from land and atmosphere. Resuspension is a process, which might ... -
Spatial distribution and conservation planning of seabed biological diversity
(2011-11-18)Knowledge of spatial patterns of biota has become a commodity for conservation practitioners and spatial ecologists alike. This type of information enables the identification of representative and unique biological features ... -
Environmental, nutritional and endocrine regulation of metabolic processes in fish
(2011-11-18)Due to seasonal variations in temperature and food availability, fish in temperate regions should be able to make metabolic adjustments to ensure that enough energy is available for the maintenance of basal processes. ... -
New insights in contact allergy and drug delivery. A study of formulation effects and hapten targets in skin using two-photon fluorescence microscopy
(2011-11-08)The skin is a remarkable barrier, protecting us from invasion of e.g. harmful microorganisms and UV-radiation. However, the skin is not adopted to resist repeated exposure to the multitude of xenobiotics introduced into ... -
Conformational Dynamics of Rhodopsins Visualized by Time-resolved Wide Angle X-ray Scattering
(2011-10-27)Rhodopsins are a family of light-sensitive proteins found in the cellular membranes of a wide range of living organisms. These membrane proteins share a common molecular architecture and are able to use light energy ... -
