Popular Abstract in Swedish Större delen av den kunskap vi har om Universum får vi genom att undersöka det ljus som olika kosmiska objekt sänder ut. Det synliga ljuset från en stjärna består av kontinuerlig strålning (Planckstrålning) vars färg ger ett mått på temperaturen av stjärnans yta på samma sätt som färgen hos upphettade metallföremål. Vid en närmare undersökning av stjärnans spektrum kan The new generation of high resolution astronomical instruments such as the Hubble Space Telescope (HST) or the Very Large Telescope (VLT) has renewed the demand for accurate atomic parameters like wavelengths, oscillator strengths and line profiles accompanied by reliable uncertainty estimates. Fourier transform spectroscopy has proven to be a powerful tool when measuring these parameters. In this

Nematophagous fungi are parasites of nematodes, thus they have been considered and tested for biological control of parasitic nematodes, but so far with limited success. Due to the fact that the nematode cuticle is composed of proteins it is likely that fungal extracellular proteases are involved in the infection of nematodes. I have isolated a gene (designated PII) encoding an extracellular cutic

Design starts with a cognitive model and ends with a solution worked out in a way that fits into the human context of meaning which is socially decided. The bridge between the cognitive model and the final system, or thing, is a proper description that has to be possible to socially communicate. The necessary description part leads to the understanding that design, like sciences, is a kind of lear

Popular Abstract in Swedish Stora förändringar har skett i jordbrukslandskapet under det senaste drygt halva århundradet. Ett allt intensivare jordbruk med krav på större skördar för att möta en allt större efterfrågan på livsmedel har satt sina spår. För att klara de högre kraven, men också som en följd av den teknologiska utvecklingen, så har jordbruket rationaliserats. Landskapet har strukturerAgricultural intensification has caused severe declines among biodiversity in European farmland over the last half century. The transformation of the agricultural landscape has led to reduced availability of key resources such as food, nesting habitat and shelter. In this thesis I have investigated a way of ameliorating the negative effects of agricultural intensification, through the creation of

An anthology of letters from church fathers and their Christian contemporaries, third to sixth centuries. Translated in full from the original Latin and Greek into Swedish.

The concept of vandalism is analyzed as a symbolic act. An analysis of vandalism from a situational-positivistic, or a motivational-psychological, approach hardly gives an understanding of vandalism as a meaningful individual and social act. A humanistic and cultural perspective can supply ways to understand a nonprescribed behavior such as vandalism. The original meaning of vandalism is plunderin

The performance and convergence behavior of the iterative schemes for decoding two-dimensional product codes are investigated. The decoding trajectories of the extrinsic and the a posteriori information are used as a main tool for predicting and explaining the behavior of the iterative decoding process. The component-wise optimal BCJR decoder is compared to the suboptimal max-log-MAP decoder and t

Many stream ciphers use irregular clocking to introduce nonlinearity to the keystream. We present three distinguishers on irregularly clocked linear feedback shift registers. The general idea used is to find suitable linear combinations of keystream bits, here called samples, that are drawn from a biased distribution. We describe how to place windows around the estimated positions around members

Popular Abstract in Swedish Modern gastroenterologi är till stora delar helt beroende av resultat från gastrointestinal endoskopi och många av de sjukdomar som hänförs till denna specialitet kan också behandlas med modern endoskopisk och minimal invasiv teknik. Gastroskopi är förstahandsundersökning av patienter med såväl kroniska som akuta symptom från övre gastrointestinalkanalen. Den gastroskopChromoendoscopy, endoscopic tissue staining, is an adjunctive method using chemical agents applied to the mucosal surface in order to aid gastrointestinal endoscopic diagnosis and therapy. Acid producing mucosa in the GI tract may be visualized endoscopically by Congo red staining in combination with stimulation of gastric acid production. Congo red is a reactive indicator dye that changes color f
