Education is the foundation for achieving sustainable development. The United Nations Decade of Education for Sustainable Development declared from January 2005 to December 2014 demands a concerted effort to expand environmental education around the world. The Young Masters Program is an international education course, which utilises the internet to connect students, teachers, and tutors in differ
In order to mimic dinuclear active sites of some non-heme diiron proteins, ten new polydentate and potentially dinucleating ligands have been synthesized. Each ligand contains a carboxylate moiety designed to bridge two metal atoms. These central carboxylate moieties are derived from substituted benzoic acids that in turn are linked to terminal nitrogen or oxygen donors by spacers so that framewor
An electrochemical cell has been developed enabling amperometric steady-state- and flow-injection measurements with screen-printed arrays consisting of eight working electrodes (circle divide = 1 mm) arranged radially around a printed Ag/AgCl reference electrode in the centre. The cell contained a rotator, providing similar hydrodynamics over all the working electrodes in the array, which was manu
The weighted oscillator strengths (gf) and the lifetimes presented in this work were carried out in a multiconfiguration Hartree-Fock relativistic approach. In this calculation, the electrostatic parameters were optimized by a least-squares procedure, in order to improve the adjustment to experimental energy levels. This method produces gf-values that are in better agreement with intensity observa
MRI and CT are modalities appropriate for liver imaging. To obtain higher sensitivity in diagnoses of focal lesions in the liver, contrast media (CM) are used. Non-specific extracellular CM are not optimal as they rapidly diffuse into both normal tissue and tumorous tissue. By two different mechanisms, the hepatobiliary route and targeting to the reticuloendothelial system, agents may accumulate i
Aim: To study the influence of specific factors and events during pregnancy and the perinatal period on the risk of children developing inflammatory bowel disease. Methods: Population-based national register study. Linkage between the Swedish Medical Birth Register and the Swedish Hospital Discharge Register during the period 1987 to 2000 identified 455 singleton infants who later developed inflam
The budding yeast species Saccharomyces castellii has provided important new insights into molecular evolution when incorporated in comparative genomics studies and studies of mitochondrial inheritage. Although it shows some diversity in the specific molecular details, several analyses have shown that it contains many genetic pathways similar to those of S. cerevisiae. Here we have investigated th

Popular Abstract in Swedish I denna avhandling studerar jag tvådimensionella geometriska optimeringsproblem. Gemensamt för många praktiskt och teoretiskt intressanta problemställningar inom området är att det är mycket svårt att ta fram optimala lösningar. Det tar helt enkelt alltför lång tid att undersöka alla möjligheter för probleminstanser med stora mängder indata då beräkningstiden växer expoIn this thesis I study two-dimensional geometric optimization problems for which it is difficult to find efficient, exact, deterministic algorithms. All known solutions to these problems require time that is exponential in the total size of the input. The work done in this thesis is a contribution to the research directed at attacking and coping with such NP hard problems in computational geometry
This study was undertaken to establish the most reliable breaker depth index formula that will yield satisfactory predictions for a wide range of hydraulic and beach conditions. The applicability of six existing formulas for computing the breaker depth index was examined with the use of a large amount of published laboratory data (524 cases collected from 22 sources). The behavior of these formula
Finding work for people with severe physical disabilities is not easy. This master thesis aims to investigate the possibility of creating new job opportunities for these people, using speech recognition. One possibility is to construct an application where a person works in a callcentre by using his/her voice. To test the idea a co-operation with the callcentre at Trygg Hansa in Malmö was initiate
To allow the user interface in a mobile phone more space, slide modules are implemented. The usage of slide modules introduces many new challenges when designing a mobile phone. New solutions to these challenges is the main scope for this thesis. Nokia currently has several different slide phones out on the market implementing some sort of slide module. The slide module provides extra space for th
The purpose of this Master’s Thesis was to examine different usage applications for animations and to develop one or several animated products for Sony Ericsson Mobile Communications AB. The overall objective was to develop an animated tool for information purposes and to investigate different interesting fields of application for the animated products. The goal was also to show the procedure of c
Patents on traditional knowledge and the issue of biopiracy has been a debated issue since the Uruguay Round in the early 1990s. In order to handle this problem, the United Nations established the Convention on Biological Diversity and a subsidiary working group on Access and Benefit Sharing. This is supposed to help traditional knowledge holders claim their rights to benefit sharing when commerci
A great number of studies have explored the motivations that drive software developers to devote their time and efforts to contribute to Open Source Software Development (OSSD) projects. Previous studies have stated that both intrinsic and extrinsic motivations are important, however there have been different opinions regarding their relative value. This study further researches OSSD motivations a
The purpose of this thesis is to study beam-cavity interactions, with a focus on how to maintain an unperturbed acceleration field in a conducting cavity with a proton beam present. The impact on a cavity acceleration field from different perturbation sources is investigated through computer simulations of a theoreti- cal model based on a resonant circuit. Perturbations from the RF input pulse to
I höst kommer rymdobservatoriet Gaia att sändas upp. Ett av dess mål är att mätapositionen av stjärnor med väldigt hög noggrannhet, denna positionsbestämning kallas astrometri. Gaias noggrannhet är såpass bra att det kommer bli möjligt att även mäta hur planeter när de färdas i sina banor runt stjärnor påverkar positionen av stjärnan. Astrometri kan inte ge en fullständig bild av hur planeten rörContext: The Gaia satellite will be provide astrometry with micro-arcsecond accuracy. This will allow for the determination of the orbital elements of exoplanets with measurable astrometric signature. Astrometry alone is not be able to disentangle an ambiguity in the orientation of planetary orbits, just as radial velocity is only able to give the mass of orbiting planets combined with multiplicat
